7th May 2011, Saturday Breaking News: Person Revived after 96 Minutes of CPR CA 54-year-old man with post MI ventricular fibrillation regained spontaneous circulation after a dozen defibrillator shocks and continuous CPR for 96 minutes with full physical and neurological recovery reports Dr Roger D. White at the Mayo Clinic in Rochester, Minn in a case report published online April 20 in the Mayo Clinic Proceedings. The patient was resuscitated for initial 31 minutes by the emergency staff along with DC shocks. At the 31st minute a helicopter transport crew arrived and continued applying defibrillator shocks to the man who did not have a pulse, yet showed signs of systemic blood flow as measured by an end-tidal carbon dioxide sensor. The team administered a total of 12 defibrillator shocks and kept the patient’s blood flowing with continuous chest compressions. A key piece of technology on the scene was capnography, which measures how much blood is flowing through the lungs and subsequently to other organs. Capnography has been used to monitor patients in operating rooms but is not often used by ER when treating cardiac arrest. As the measurement remained sufficiently high, the rescuers were encouraged to continue resuscitation efforts. At the hospital, he was stabilized and taken to the cath lab and was stented for 100% occlusion in the mid-left anterior descending coronary artery. The persistent low blood pressure was stabilized with an intra-aortic balloon pump. The patient was discharged after 10 days with no neuro damage. Lessons learned • It’s the only case where a person has been revived after 96 minutes of clinical death • We had a similar case where CPR was continued for 45 minutes • GB Pant reports a similar case with revival after an hour and with stenting (Dr Vijay Trehan) • Medicolegal implications: Do not stop resuscitation for up to 100 minutes and make sure you measure E tube CO2 levels • Transport the patient to nearest cardiac hospital for possible angiography and IABP (intra aortic balloon pump), if required.
Data from well-known medical journals across the world document emergence of similar metallo-b-lactamases bacteria from at least 28 countries including South Korea, Japan, China, Greece, Brazil, Australia, Italy, Portugal and Spain. Detection of NDM-1 is important as it shows an increasing presence of drug-resistant bacteria. —Indian Express

Obesity Update Life after Bariatric Surgery Post operative (Stage I) Full liquids: Once clear liquids are tolerated, a full liquid diet is started. This will last for one week. Foods in this stage should be smooth (no lumps or seeds). Thicker foods such as plain or ‘lite’ yogurt, sugar free pudding, or baby food in small frequent meals (i.e., 1/4 cup of low fat milk). are usually tolerated. Protein supplement is crucial at this point.
NDM-1 in Pune: Researchers Superbug gene detected in 20 patients Researchers from the government-run B J Medical College (BJMC) and the National Centre for Cell Science (NCCS), in preliminary findings of a study to find the New Delhi metallobeta lactamase1 (NDM-1) incidence in Pune, reported the strain in the city in 20 cases. In Pune, clinical microbiologists at the government-run BJMC and Sassoon General Hospital and the NCCS collected samples of blood, urine and pus from 3,172 patients at Sassoon General Hospital in the last two months and found that 885 had gram negative bacilli (bacteria which causes a majority of infections). Of these 885 as many as 181 patients were resistant to the carbapenem family of drugs while 20 were detected with the NDM-1 gene. NDM-1 is an enzyme that makes bacteria resistant to a broad range of beta-lactam antibiotics including antibiotics of the carbapenem family, a mainstay for treatment of antibiotic-resistant bacteria. The gene for NDM-1 is a member of a large gene family that encodes beta-lactamase enzymes called carbapenemases. Infections with these bacteria are hard to treat successfully, say microbiologists.
WHO Warns of Enormous Burden of Chronic Disease Chronic illnesses like cancer, heart disease and diabetes have reached global epidemic proportions and now cause more deaths than all other diseases combined, the World Health Organization (WHO) said on Wednesday. In its first worldwide report on so-called noncommunicable diseases, or NCDs, the United Nations health body said the conditions caused more than half of all deaths in 2008 and pose a greater threat than infectious diseases such as malaria, HIV and tuberculosis (TB) – even in many poorer countries. NCDs, which include heart disease, lung diseases, cancer and diabetes, accounted for 36 million, or 63 percent, of the 57 million deaths worldwide in 2008. Millions of lives could be saved and much suffering avoided if people did more to avoid risk factors like smoking, drinking and being overweight, the WHO said. Pediatric Update What is Candida Score? In non–neutropenic critically ill patient Multifocal colonization 1 point Surgery 1 point TPN 1 point Severe sepsis 2 points Cut off value 2.5 Sensitivity 81%, specificity 74% Score >2.5 - sensitive indication of proven infection (7.75 times more likely to have infection). −Dr. Neelam Mohan, Director Pediatric Gastroenterology, Hepatology and Liver Transplantation, Medanta - The Medicity

Medi Finance Update Investment tips An investment in bank’s fixed deposits (FDs) has low risk but minimum gain. A bank gives 6% interest with inflation of 5%; the yield is only 1%. Company FDs can be invested in only after thorough analysis of the company. Lab Update Complete Blood Count (CBC) CBC measures the amount of various types of blood cells in a sample of your blood. Blood cancers like AML, ALL, CML, CLL may be detected using this test if too many or too few of a type of blood cell or abnormal cells are found. —Dr Arpan Gandhi and Dr Navin Dang

Broccoli Compound may Combat COPD
I
n chronic obstructive pulmonary disease (COPD), damage to immune cells limits the lungs’ ability to fight off bacterial infections. According to a new study, boosting the activity of a specific molecule in these cells can restore their defensive powers. In patients with COPD, immune cells called macrophages lose their ability to engulf and remove bacteria, making the lungs more vulnerable to infection. Until now, no one knew how to reverse this damage to the macrophages. A team of scientists at Johns Hopkins University, led by Drs Shyam Biswal and Robert Wise, investigated why macrophages don’t work properly in COPD patients. Previous research suggested that a process called oxidative stress might be to blame. Oxidative stress occurs when the body can’t effectively neutralize damaging compounds called peroxides and free radicals.

A molecule called Nrf2 can cause cells to make more antioxidants, which neutralize these harmful compounds. Previous studies found reduced Nrf2 activity in severe COPD. The scientists suspected that increasing Nrf2 activity might restore the ability of macrophages to remove bacteria. To test their theory, the team used a chemical called sulforaphane, which is known to activate Nrf2. A precursor of sulforaphane is found in broccoli. The research was cosponsored by NIH’s National Heart, Lung and Blood Institute (NHLBI) and National Institute of Environmental Health Sciences (NIEHS). The results appeared in the April 13, 2011, issue of Science Translational Medicine. The researchers first took macrophages from the lungs of patients with moderate COPD. When they treated these macrophages with sulforaphane, they saw higher Nrf2 levels in the cells. Sulforaphane treatment also boosted the ability of cultured macrophages to clear 2 of the major types of bacteria that infect COPD patients. Macrophage uptake of bacteria rose 300% after treatment, whether the cells came from smokers or nonsmokers. Experiments in mouse and human cells revealed that sulforaphane, through Nrf2, increases levels of a receptor called MARCO on macrophages. MARCO activity was necessary for macrophages to engulf bacteria after sulforaphane treatment. Mice exposed to smoke had lower levels of MARCO. Furthermore, smoke-exposed mice genetically engineered to lack Nrf2 had more lung inflammation and higher levels of bacteria. The team gave sulforaphane with a nebulizer to mice exposed to smoke and found that the mice’s lungs showed reduced inflammation and bacterial burden. The researchers also gave human COPD patients broccoli sprout extract enriched with sulforaphane for two weeks. The patients taking the extract had higher levels of MARCO and Nrf2-controlled antioxidants in their blood cells. A NHLBI-sponsored clinical trial is now being conducted to test if sulforaphane can provide relief to patients with COPD. n

Liv.52 DS Syrup in the Management of Alcoholic Hepatitis: An Open Label Study S Ganesh*, D Palaniyamma**, Suprabha Hegdeâ€
Abstract The course of alcoholic liver disease is prolonged and variable and hence evaluation of beneficial effects of therapy is essential. The aim of the present study was to evaluate clinical efficacy and safety of Liv.52 DS syrup in patients suffering from alcoholic hepatitis (AH). An open clinical study was carried out in 50 patients with AH; all patients were given orally Liv.52 DS syrup (2 tsp) t.i.d. for two months. Patients were evaluated at monthly intervals. The parameters used were: Jaundice, anorexia, nausea/vomiting, fever, pruritus and liver function tests. Routine hematology was done before and after treatment to assess the safety profile. Treatment with Liv.52 DS syrup significantly improved clinical signs and symptoms as well as biochemical parameters. There were no drop outs in the trial period, indicating excellent patient compliance. There were no adverse drug reactions. No difference in hematological parameters was observed after treatment, which clearly indicates safety of the drug. The overall impression by the investigator showed marked improvement in 50%, moderate improvement in 28%, slight improvement in 10% and no change in 12% cases. Overall impression by the patients showed marked improvement in 56%, moderate improvement in 22%, slight improvement in 6% and no change in 16%. So, it can be concluded that Liv.52 DS syrup is safe and effective in patients suffering from AH. Key words: Alcoholic hepatitis, Liv.52 DS syrup

lcoholic liver disease (ALD) encompasses a spectrum of injury, ranging from simple steatosis to frank cirrhosis. It is common for patients with ALD to share risk factors for simultaneous injury from other liver insults (e.g., coexisting nonalcoholic fatty liver disease, or chronic viral hepatitis).1 The term alcoholic hepatitis (AH) was first used by Beckett et al in 1961.2 Despite this longstanding observational relationship between alcohol consumption and liver disease, significant work has been required to determine quantity of alcohol to be consumed to cause liver disease, and which cohort of patients are at highest risk of developing significant liver injury.2,3 AH is a common and life-threatening cause of liver failure, especially when severe. It is usually subacute and has been developing for weeks to months before it becomes clinically apparent. Patients with AH usually have a history of drinking heavily for many years.4

Possible factors that affect development of liver injury include the dose, duration and type of alcohol consumption, drinking patterns, ethnicity and associated risk factors including obesity, iron overload, concomitant infection with viral hepatitis, and genetic factors. Geographic variability exists in the patterns of alcohol intake globally.5 The majority drink small or moderate amounts and do so without evidence of clinical disease.6-8 A subgroup, however, drinks excessively, develop physical tolerance and withdrawal, and are diagnosed with alcohol dependence.9 A second subset, alcohol abusers and problem drinkers, includes those who engage in harmful use of alcohol, defined by the development of negative social and health consequences of drinking (e.g., unemployment, loss of family, organ damage, accidental injury or death).10 ALD takes a prolonged and varied course; hence, evaluation of beneficial effects of therapy has been difficult. Multiple stages of the disease may be present simultaneously in a given individual.11,12 These are often grouped into three histological stages of ALD: Fatty liver or simple steatosis, AH and chronic hepatitis with hepatic fibrosis or cirrhosis. These latter stages may also be associated with several histologic changes (which have varying degrees of specificity for ALD), including the presence of Mallory’s hyaline, megamitochondria or perivenular and perisinusoidal fibrosis.11 Fatty 645
original study liver develops in about 90% of individuals who drink >60 g/day of alcohol,13 it may also occur in individuals who drink less.14 Uncomplicated fatty liver is usually asymptomatic and self-limited, and may be completely reversible with abstinence after about 4-6 weeks.15 Despite abstinence, progression to fibrosis and cirrhosis occurs in 5-15%. In a study, continued alcohol use (40 g/day) increased the risk of progression to cirrhosis to 30%, and fibrosis or cirrhosis to 37%.16 Fibrosis starts in the perivenular area and is affected by the amount of alcohol ingested.17,18 Perivenular fibrosis and deposition of fibronectin occurs in 40-60% of patients who ingest >40-80 g/day for an average of 25 years. The diagnosis of ALD is based on a combination of features, including a history of significant alcohol intake, clinical evidence of liver disease and supporting laboratory abnormalities.19 The diagnosis of ALD is made by documentation of alcohol excess and evidence of liver disease.20 Many laboratory abnormalities, including elevated serum aminotransferases, have been found in patients with alcoholic liver injury, and used to diagnose ALD.21 In severe AH, serum aspartate aminotransferase (AST) is typically elevated to a level of 2-6 times the upper limits of normal. AST levels >500 IU/l or an alanine aminotransferase (ALT) >200 IU/l are uncommon in AH (other than alcoholic foamy degeneration, or concomitant acetaminophen overdose),22 and should suggest another etiology. AST/ALT ratio is >2 in about 70% patients, but this may be of greater value in patients without cirrhosis.23-25 Ratios >3 are highly suggestive of ALD.26 Palpation of the liver may be normal in ALD, and does not provide accurate information regarding liver volume.27 Physical findings more commonly observed are: Parotid enlargement, Dupuytren’s contracture and especially those signs associated with feminization.28 Specific features associated with an increased risk of mortality over one year: Hepatic encephalopathy (4.0), presence of visible veins across the anterior abdominal wall (2.2), edema (2.9), ascites (4.0), spider nevi (3.3) and weakness (2.1).29 An hepatic bruit in the setting of AH has been reported.30 ALD does not exist in isolation; other organ dysfunction related to alcohol abuse may coexist, including cardiomyopathy,31,32 skeletal muscle wasting,33 pancreatic dysfunction and alcoholic neurotoxicity.34 These should be looked for during clinical examination for appropriate treatment of the same.35 The diagnosis of fatty change, established cirrhosis and 646
hepatocellular carcinoma may be suggested by ultrasound, CT scan or magnetic resonance imaging (MRI) and confirmed by other laboratory investigations.36,37 Therapy of ALD is based on the stage of disease and the specific goals of treatment.38,39 Complications of cirrhosis, including evidence of hepatic failure (encephalopathy) as well as portal hypertension are treated as in patients with non-ALD, with additional attention given to other organ dysfunction associated specifically with alcohol.39 Abstinence is the most important therapeutic intervention for patients with ALD.40 It improves outcome and histological features of hepatic injury, reduces portal pressure and decreases disease progression40-43 but over one year, relapse rates range from 67 to 81%.44 Several medications have been used to help sustain abstinence. One of the first agents to be used was disulfiram. Naltrexone is a pure opioid antagonist and controls alcohol craving. However, it can also cause hepatocellular injury. Acamprosate (acetylhomotaurine) is a novel drug with structural similarities to the inhibitory neurotransmitter gamma-aminobutyric acid (GABA), and is associated with a reduction in withdrawal symptoms.45 Pentoxifylline, a nonselective phosphodiesterase inhibitor, has a moderate anticytokine effect attributed to reduced transcription of the tumor necrosis factor (TNF) gene.46 Anti-TNF antibody infliximab, the chimeric human and mouse monoclonal antibody, binds to TNF and blocks its biological effects.47 Other measures include nutritional supplements, corticosteroids, antioxidants and in severe acute cases, liver transplantation.48-51 Liv.52 DS syrup, a polyherbal formulation, was evaluated in patients with AH. It is a hepatospecific formulation, designed for the management of liver disorders. It restores metabolic efficiency of liver in various forms of hepatocellular jaundice like infective and chronic active hepatitis, druginduced hepatitis and alcohol-induced hepatic damage. Aim To evaluate the clinical efficacy and safety of Liv.52 DS syrup in patients suffering from AH. Material and Methods Study Design
An open clinical study in 50 patients with AH and attending the Malar Hospitals, Chennai, Tamil Nadu, India, after obtaining Ethics Committee approval and applicable regulatory authorities. Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011
original study Inclusion criteria: Fifty patients with AH aged >18 years with signs and symptoms of hepatitis (jaundice, anorexia, nausea/vomiting, fever, pruritus) and abnormal liver function tests (LFT) provided they could attend on all the specified assessment visits and willing to give the informed consent, and comply with the study procedures.
test or paired student’s t-test. The minimum level of significance was fixed at p < 0.05. Statistical analysis was carried out using GraphPad Prism Software (Version 4.01).
Exclusion criteria: Severe hepatic cirrhosis, hepatic encephalopathy, esophageal varices, severe systemic illness and those who were not ready to provide informed consent or comply with the study procedures.
Fifty male patients (mean age of 50.36 ± 8.46 years) were included in the study. Duration of alcohol use was 10.85 ± 5.72 years and baseline weight was 75.78 ± 6.40. All patients received Liv.52 DS syrup in recommended doses for two months (Table 1). At entry, 21 patients had jaundice, which improved with treatment; symptoms persisted in only 10 patients at one month (p < 0.03) and seven patients at two months (p < 0.003). All 50 patients had anorexia and nausea, which improved significantly at one month (p < 0.0001) and at two months (p < 0.0001). Four patients had fever that subsided within 3-4 days of treatment as elicited by the subjects at one month. Pruritus, present in eight cases at entry, reduced to three cases at one month and two cases at two months (Table 2). LFT parameters (SGOT, SGPT, serum bilirubin, total protein, albumin and globulin) showed improvement. SGOT, SGPT and serum bilirubin showed a significant reduction (p < 0.0001) at the end of study period versus the baseline values (Table 3).
Study Procedure
Study subjects were explained the nature of study; written consent was obtained. Detailed history of alcohol consumption including medical history was noted. Clinical examination was done, following which the patients were given orally Liv.52 DS syrup (2 tsp) t.i.d. for two months. Follow-up and Assessment
Patients were evaluated at monthly intervals for study period. Assessment was done using subjective and objective parameters, which were scored arbitrarily. Parameters evaluated were jaundice, anorexia, nausea/ vomiting, fever, pruritus and LFT. Adverse effects (AE), as volunteered by the patients, were recorded. Scoring was done as follows: 0-Nil, 1-Mild, 2-Moderate and 3-Severe. Primary endpoints: Clinical recovery from the signs and symptoms and normalization of LFTs. Secondary endpoints: Incidence of any AE and the overall compliance to Liv.52 DS syrup.
Results
The overall impression by the investigator showed marked improvement in 50%, moderate improvement in 28%, slight improvement in 10% and no change in 12%. The overall impression by the patients showed marked improvement in 56%, moderate improvement in Table 1. Demographic Details Particulars

22%, slight improvement in 6% and no change in 16%. On clinical examination, pulse (76.88 ± 4.61), blood pressure (120.96 ± 4.59/80.36 ± 4.83) and other systemic examination were normal in all patients. There were no changes in routine hematological tests (hemoglobin, white cell count). No AE were reported following treatment, which clearly indicates the safety of the drug. No drop out was observed during the trial period indicating excellent patient compliance. Discussion In the present study, there were significant improvements in clinical and liver function parameters of AH with Liv.52 DS syrup treatment. Its efficacy is due to the synergistic actions of the potent constituent hepatoprotective herbs, which include: Capparis spinosa, Cichorium intybus, Solanum nigrum, Terminalia arjuna, Cassia occidentalis, Achillea millefolium and Tamarix gallica. P-Methoxybenzoic acid from C. spinosa has potent hepatoprotective activity against chemically-induced hepatotoxicity and prevents rise of malondialdehyde 648
(plasma and hepatic) and enzymes (AST and ALT).52-54 It improves functional efficiency of liver; has protective action on liver histology, and a salutary effect on liver glycogen and serum proteins.55 Flavonoids of C. spinosa have significant antioxidant activity.56 C. intybus increases circulating leukocytes, splenic plaqueforming cells, hemagglutination titers, secondary IgG antibody response, phagocytic activity, natural killer cell activity, cell proliferation and interferon-g secretion.57,58 It hepatoprotective activity suppresses oxidative DNA degradation in tissue debris.59 It also has potent antioxidant action.60,61 S. nigrum protects DNA against oxidative damage62 and is also a potent scavenger of hydroxyl and diphenylpicrylhydrazyl radicals.63 Significant inhibition of cytotoxicity, and hydroxyl radical scavenging potential against gentamicin-induced toxicity has been noted.64 T. arjuna reduces cholesterol levels and is also useful in liver disorders.65,66 It has potent antioxidant activity.67 Arjunaphthanoloside inhibits nitric oxide (NO) production, and terminoside A decreases inducible NO synthase levels in lipopolysaccharide-stimulated peritoneal macrophages.68 It has antiviral and antibacterial activities.69,70 C. occidentalis exerts significant hepatoprotective effects in chemically-induced liver damage by modulating hepatic enzymes.71,72 A. millefolium is beneficial in chronic hepatitis73 and has antihepatoma activity.74 T. gallica is a hepatic stimulant, digestive and hepatoprotective, and has a salutary effect on liver glycogen and serum proteins.75 Liv.52 DS syrup restores metabolic efficiency of the liver by protecting the parenchyma and promoting hepatocellular regeneration. The antiperoxidative activity of Liv.52 DS syrup prevents loss of functional integrity of the cell membrane, maintains cytochrome P450 enzyme system, shortens the disease recovery period, and ensures early restoration of hepatic functions in infective hepatitis.76 It protects against alcohol-induced hepatic damage by facilitating rapid elimination of acetaldehyde, the toxic intermediate metabolite of alcohol metabolism.77,78 It decreases lipotropic activity in chronic alcoholism, and prevents fatty infiltration of the liver. As a daily health supplement, it improves appetite, digestion and assimilation processes, and promotes weight gain. As a whole, Liv.52 DS syrup has hepatoprotective, antioxidant, antimicrobial and anti-inflammatory properties. Conclusion This clinical study has clearly shown significant improvement in clinical as well as biochemical parameters Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011
original study of AH with Liv.52 DS syrup. No differences in hematological parameters and no adverse drug reactions reported following treatment for the study period clearly indicate its safety.

Differentiation and Diagnosis of Tremor Paul Crawford, Ethan E. Zimmerman
Abstract Tremor, an involuntary, rhythmic, oscillatory movement of a body part, is the most common movement disorder encountered in clinical practice. Rest tremors occur in a body part that is relaxed and completely supported against gravity. Action tremors occur with voluntary contraction of a muscle and can be further subdivided into postural, isometric, and kinetic tremors. All persons have low-amplitude, high-frequency physiologic tremors at rest and during action that are not reported as symptomatic. The most common pathologic tremor is essential tremor. In one-half of cases, it is transmitted in an autosomal dominant fashion, and it affects 0.4 to 6 percent of the population. More than 70 percent of patients with Parkinson disease have tremor as the presenting feature. This tremor is typically asymmetric, occurs at rest, and becomes less prominent with voluntary movement. Features consistent with psychogenic tremor are abrupt onset, spontaneous remission, changing tremor characteristics, and extinction with distraction. Other types of tremor are cerebellar, dystonic, drug- or metabolic-induced, and orthostatic. The first step in the evaluation of a patient with tremor is to categorize the tremor based on its activation condition, topographic distribution, and frequency. The diagnosis of tremor is based on clinical information obtained from a thorough history and physical examination. For particularly difficult cases, single-photon emission computed tomography to visualize the integrity of the dopaminergic pathways in the brain may be useful to diagnose Parkinson disease. Key words: Tremor, Parkinson disease, single-photon emission computed tomography

remor is an involuntary, rhythmic, oscillatory movement of a body part. It is the most common movement disorder encountered in clinical practice.1-3 There is no diagnostic standard to distinguish among common types of tremor, which can make the evaluation challenging. However, establishing the underlying cause is important because prognosis and specific treatment plans vary considerably. History and physical examination can provide a great deal of certainty in diagnosis. The most common tremor in patients presenting to primary care physicians is enhanced physiologic tremor, followed by essential tremor and parkinsonian tremor.1,3-6 All tremors are more common in older age.7 Classification
completely supported against gravity (e.g., when resting an arm on a chair). It is typically enhanced by mental stress (e.g., counting backward) or movement of another body part (e.g., walking), and diminished by voluntary movement of the affected body part.3,9,10 Most tremors are action tremors, which occur with voluntary contraction of a muscle. Action tremors can be further subdivided into postural, isometric, and kinetic tremors.8,9 A postural tremor is present while maintaining a position against gravity. An isometric tremor occurs with muscle contraction against a rigid stationary object (e.g., when making a fist). A kinetic tremor is associated with any voluntary movement and includes intention tremor, which is produced with target-directed movement.2
Tremors are classified as either resting or action.8 A rest tremor occurs in a body part that is relaxed and

Review ARticle essential tremor often causes severe social embarrassment, and up to 25 percent of those afflicted retire early or modify their career path.8 Essential tremor is an action tremor, usually postural, but kinetic and even sporadic rest tremors have also been described.3,11 It is most obvious in the wrists and hands when patients hold their arms in front of themselves (resisting gravity); however, essential tremor can also affect the head, lower extremities, and voice.12 It is generally bilateral, is present with a variety of tasks, and interferes with activities of daily living.1,5 In a series of 200 Italian patients referred to a neurologist for evaluation of tremor, 15 percent had uncommon clinical features that included postural, action, rest, orthostatic, and writing tremors, and 10 percent had tongue or facial dyskinesia.13 Diagnostic criteria have been proposed, but none have been accepted universally. Persons with essential tremor typically have no other neurologic findings; therefore, it is often considered a diagnosis of exclusion.12 If the tremor responds to a therapeutic trial of alcohol consumption (two drinks per day), the diagnosis of essential tremor is assured. Parkinsonism
Parkinsonism is a clinical syndrome characterized by tremor, bradykinesia, rigidity, and postural instability. Many patients will also have micrographia, shuffling gait, masked facies, and an abnormal heelto-toe test.10,14-16 Causes of parkinsonism include brainstem infarction, multiple system atrophy, and medications that block or deplete dopamine, such as methyldopa, metoclopramide, haloperidol, and risperidone.9,10 Idiopathic Parkinson disease is a chronic neurodegenerative disorder; its prevalence increases with age. It is the most common cause of parkinsonism.17 More than 70 percent of patients with Parkinson disease have tremor as the presenting feature. The classic parkinsonian tremor begins as a low-frequency, pillrolling motion of the fingers, progressing to forearm pronation/supination and elbow flexion/extension. It is typically asymmetric, occurs at rest, and becomes less prominent with voluntary movement. Although rest tremor is one of the diagnostic criteria for Parkinson disease, most patients exhibit a combination of action and rest tremors.3,11 652
Enhanced Physiologic Tremor
A physiologic tremor is present in all persons. It is a low-amplitude, high-frequency tremor at rest and during action that is not reported as symptomatic. This tremor can be enhanced by anxiety, stress, and certain medications and metabolic conditions. Patients with a tremor that comes and goes with anxiety, medication use, caffeine intake, or fatigue do not need further testing.1,8 Drug- and Metabolic-induced Tremors
Dozens of medications can cause or exacerbate tremor (Table 1).1,3,8 Patients with new-onset tremor should have a comprehensive medication review with specific attention to medications (prescribed and over-the-counter) started proximal to the onset of tremor.8 Medications particularly prone to inducing or exacerbating tremor are those that stimulate the sympathetic nervous system (e.g., amphetamines, terbutaline, pseudoephedrine) and psychoactive medications (e.g., tricyclic antidepressants, haloperidol, fluoxetine).1,8,12 When medication review reveals a likely culprit, a trial off of this medication should be attempted. Metabolic causes of tremor are varied.8 Initial workup of tremor may include blood testing for hepatic encephalopathy, hypocalcemia, hypoglycemia, hyponatremia, hypomagnesemia, hyperthyroidism, hyperparathyroidism, and vitamin B12 deficiency.8 Table 1.

Review ARticle Cerebellar Tremor
The classic cerebellar tremor presents as a disabling, low-frequency, slow intention or postural tremor, and is typically caused by multiple sclerosis with cerebellar plaques, stroke, or brainstem tumors. Other neurologic signs include dysmetria (overshoot on finger-to-nose testing), dyssynergia (abnormal heel-to-shin testing and/or atraxia), and hypotonia.8,18 Psychogenic Tremor
Differentiation of organic from psychogenic tremor can be difficult. Features consistent with psychogenic tremor are abrupt onset, spontaneous remission, changing tremor characteristics, and extinction with distraction8,19 (Table 28,18). Often, there is an associated stressful life event.3 Based on clinical experience, the prevalence of psychogenic tremor is thought to be high, but there are no precise estimates.10 Dystonic Tremor
Dystonic tremor is a rare tremor found in 0.03 percent of the population.20 It typically occurs in patients younger than 50 years. The tremor is usually irregular and jerky, and certain hand or arm positions will extinguish the tremor. Other signs of dystonia (e.g., abnormal flexion of the wrists) are usually present.8,20 Wilson Disease
Wilson disease is a rare, autosomal recessive disorder that manifests in persons five to 40 years of age, sometimes with a â&#x20AC;&#x153;wing-beatingâ&#x20AC;? tremor (see http://
www.youtube.com/watch?v=JgDvQUwUOo0 for an example of this tremor). Serum ceruloplasmin level and 24-hour urinary copper excretion should be considered in young patients presenting with tremor to exclude this potentially life-threatening disease.17,21 Diagnostic Approach The diagnosis of tremor is based on clinical information obtained from a thorough history and physical examination.2,17 Although there is overlap and variability among the individual tremor syndromes, the intrinsic features of the tremor usually provide key diagnostic clues (Figure 12,8,10,17,19; Table 3)1,3,8,10. The first step in the evaluation of a patient with tremor is to categorize the tremor based on its activation condition, topographic distribution, and frequency. The activation condition should be described as rest, kinetic (or intention), postural, or isometric. The examiner can have the patients sit with their hands in their laps to check for rest tremor. A sequential test for postural and kinetic tremors can be done by having the patient stretch his or her arms and hands out, followed by a simple finger-tonose test.2,3 A rest tremor is virtually synonymous with parkinsonism, whereas an intention tremor often indicates a cerebellar lesion.1,10 Frequency is generally classified as low (less than 4 Hz), medium (4 to 7 Hz), or high (more than 7 Hz). The topographic distribution of the tremor (e.g., limbs, head, voice) can also provide useful information. For example, a high-frequency tremor that involves the head is much more likely to be essential tremor than parkinsonian tremor.2,3 Several historical clues

can play important roles in the differentiation of tremors (Figure 22,8,10,17,19). Tremor in older patients is more likely to be parkinsonian or essential tremor. Patients with sudden onset of tremor should be evaluated to determine if the tremor is caused by 654
medications, toxins, a brain tumor, or a psychogenic cause. Patients with a gradual onset of tremor should prompt questions about Parkinson disease. Most tremors are symmetric, but brain tumors can cause tremors to lateralize to one side. Caffeine and Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011

fatigue are often exacerbating factors in essential tremor; alleviating factors are difficult to find. A search must be made for associated diseases (e.g., sleep disorders because fatigued muscles may amplify physiologic tremor; polyneuropathy because lack of innervations may cause small involuntary movements that are interpreted as tremor). A family history of neurologic disease or tremor suggests a genetic component, as is often seen in essential tremor. A thorough medication history should be obtained to rule out drug-induced tremor. The patient should also be screened for drugs of abuse and alcohol consumption because alcohol overuse and withdrawal can cause tremor. Conversely, small amounts of alcohol can temporarily relieve essential tremor and can be a clue to the diagnosis.2,3 The assessment of tremor also includes a careful examination for signs associated with tremor syndromes. Bradykinesia and postural abnormalities strongly suggest parkinsonism. Difficulty rising from a seated position, micrographia, reduced arm swing while walking, and masked facies are also features of bradykinesia. Postural Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011
abnormalities can be demonstrated by a positive pull test, which is when the patient stands in a neutral position and the examiner causes him or her to fall by pulling on the upper arms from behind. This can help isolate cerebellar tremor and prompt evaluation for multiple sclerosis or stroke.22 Similarly, the coactivation sign is resistance during passive movement of a tremulous limb, but with disappearance of the tremor, which indicates psychogenic tremor. The examiner should search for dystonia (i.e., sustained muscle contraction), cerebellar signs (e.g., ataxia, uncoordination), pyramidal signs, neuropathic signs, and signs of systemic disease (e.g., thyrotoxicosis). A shuffling gait is consistent with parkinsonism, whereas an unsteady stance with normal gait can indicate orthostatic tremor (a rare lower extremity disorder that produces subjective unsteadiness on standing).2,8 Videos that illustrate different features of tremor are available on the Internet. Some of the more common examples are essential tremor (http://www.youtube. com/watch?v=xVRKO-Sz0x4), parkinsonian tremor (http://www.youtube.com/watch?v=DaIN2zRQn8w), 655
Review ARticle and intention tremor (http://www.youtube.com/ watch?v=GQm8klm6ub8). Tremor in Children The diagnosis of tremor in children is poorly understood. A variety of genetic conditions are associated with tremor in children, including spinal muscular atrophy, mitochondrial diseases, Huntington disease, and fragile X syndrome. Brain tumors, hydrocephalus, nutritional deficiencies (e.g., vitamin B12), heavy metal poisoning, prescription medications, pyruvate carboxylase deficiency, and homocystinuria can also cause tremor in children. Tremor in children is potentially serious; patients should be promptly referred to a neurologist.23 Childhood tremor should also prompt an in-depth investigation to elucidate its cause.23 Imaging A variety of imaging modalities have been studied to help differentiate causes of tremor. Currently, the diagnosis of tremor remains primarily clinical, but for particularly difficult cases, single-photon emission computed tomography (SPECT) to visualize the integrity of the dopaminergic pathways in the brain may be useful to diagnose Parkinson disease. A metaanalysis found that SPECT with presynaptic radiotracers successfully differentiated Parkinson disease in an early phase from normalcy (odds ratio = 60), Parkinson disease from essential tremor (odds ratio = 210), and Parkinson disease from vascular parkinsonism (odds ratio = 105).24 The large odds ratios in this metaanalysis are caused by spectrum bias from the casecontrol design of the underlying studies. In a subsequent series of 99 patients with suspected, yet undiagnosed Parkinson disease, baseline scanning with a different type of SPECT ([123I]FP-CIT SPECT) was 78 percent sensitive and 97 percent specific, with a positive likelihood ratio of 26 and negative likelihood ratio of 0.23. Thus, positive SPECT was very good at ruling in a final diagnosis of Parkinson disease three years later.25 Plain computed tomography and magnetic resonance imaging are good choices to rule out secondary causes of tremor (e.g., multiple sclerosis, stroke) when the diagnosis of tremor is not obvious from history and physical examination.26 656

Drugs and Dreams Sarita Goyal*, Jyoti Kaushal**, MC Gupta†, Savita Verma‡
Abstract Dreams are a series of images, ideas, thoughts, emotions and sensations occurring involuntarily in the mind during certain stages of sleep. They have been described physiologically as a response to a neural process when the person is asleep while the psychological basis proposed is that they are because of reflection of the subconscious mind. Pharmacologists are of the view that medications, many hormones, neurotransmitters, herbs and supplements can alter dreams and make them more or less vivid.

reams are a series of images, ideas, thoughts, emotions and sensations occurring involuntarily in the mind during certain stages of sleep.1 The content and purpose of dreams are not fully understood although they have been a topic of interest since ages. The scientific study of dreams is known as oneirology.1 Dreams have a long history. They have been a subject of controversy and disagreement as different individuals have tried to describe in their own manner. They have been described physiologically as a response to a neural process when the person is asleep while the psychological basis proposed is that they are because of reflection of the subconscious mind. The spiritual people ascribe them to as messages from Gods. Pharmacologists are of the view that medications, many hormones, neurotransmitters, herbs and supplements can alter dreams and make them more or less vivid.2 Dreams can be of various forms i.e., pleasant dreams or frightening dreams. Frightening dreams can be either in the form of a nightmare or a night terror. A nightmare is a type of dream that arouses feelings of intense, inescapable fear, terror, distress or extreme anxiety that usually awakens the sleeper. It results in the dreamer *Demonstrator **Professor †Senior Professor and Head ‡Associate Professor Dept. of Pharmacology, Pt.

waking with full or partial recall of the dream itself. Recurrent nightmares can be because of post-traumatic stress disorders or due to other psychiatric illnesses. Nightmares are more common in women and are associated with an increase in nocturnal awakenings, sleep onset insomnia and day time memory impairment and anxiety following poor sleep.3 Night terror is an arousal disorder that usually occurs early in the sleep period. It is an episode of extreme fright during sleep without any recollection of a dream. Both nightmares and night terrors strike children much more often than adults.3 Sleep Patterns and Dreams As indicated by Davidson, Duffy and Osselton, sleep may be divided into two alternative phases: Rapid eye movement (REM) sleep and nonrapid eye movement (NREM) sleep. Although, dreams can occur in both the phases, but they primarily take place in the REM phase which is associated with lowvoltage electroencephalogram.4 NREM sleep is further divided into four stages (stage 1 to stage 4). Stage 3 and 4 constitute the deep sleep. It is reported that 80% of persons have dreams during REM sleep and sleep onset (stages 1 and 2) while 20% persons have dreams during deep sleep.5 Patients report that dreams experienced during REM sleep tend to be bizarre and detailed, with storyline plot associations. Unpleasant or frightening dreams usually occur in this period. In contrast, dreams experienced in deep sleep are more diffuse (e.g. dreams about a color or an emotion). Night terrors may occur at this time. The dreams of stages 1 and 2 are simpler, shorter and have fewer associations Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011
Review ARticle than the dreams of REM sleep.5 These phases of sleep, especially REM sleep, can be affected by a variety of drugs and hormones.6 A number of drugs used in various diseases can affect the sleep pattern and can cause dreams. Nightmares including night terrors are also associated with the use of medications which affect the neurotransmitters e.g., adrenergic, cholinergic, dopaminergic, serotonergic and gabaminergic, etc. It has been observed that almost all psychiatric drugs can influence our dreaming but even medications that would not seem suspected, such as blood pressure affecting drugs, may have an effect, some of them reducing nightmares and some increasing them. Individual differences are of course always possible. Not only the drugs used in pharmacotherapeutics lead to dreams, but even the drugs of abuse can be responsible for change in sleeping pattern and dreams.2 Pharmacotherapeutic Drugs and Dreams
Prescribed drugs used in various disease states can alter the sleeping patterns leading to dreams by affecting one or the other neurotransmitters. Drugs influencing adrenergic, aminergic, dopaminergic and cholinergic neurotransmitters have prominent role on dreams and nightmares.7 These neurotransmitters may function by modulation of the cardinal sleep stages - REM and NREM sleep.8 Antihypertensive Agents
Antihypertensive agents, in general use, affect adrenergic receptors. β-blockers and adrenergic neuron blocking agents are responsible for 34% of clinical trials in which nightmares are reported as an adverse effect.8 β-blockers which cause nightmares or dreams are: Propranolol, atenolol, betaxolol, bisopropolol, labetalol. They are known to be NREM suppressants. Adrenergic neuron blockers-guanethidine, and reserpine have probable association with nightmare reports. These drugs have been shown to affect REM sleep and thus cause dreams. Decrease in dream recall occurs with the use of both adrenergic neuron blockers (REM suppressant) and β-blockers (NREM suppressants).9 Other antihypertensive agents which may cause dreams are angiotensin-converting enzyme inhibitors (captopril, enalapril and quinapril), angiotensin receptor blocker (losartan) and calcium channel blocker (verapamil).8 Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011
Hypolipidemic Agents
Nightmares may also be a rare class effect of the statins: Simvastatin, pravastatin, fluvastatin and atorvastatin, which may be linked to REM sleep suppression.8 Drugs used in Alzheimer ’s Disease
REM sleep is affected by pharmacological alteration of cholinergic activity in the central nervous system (CNS).8 Many lines of study support the hypothesis that brainstem cholinergic neurons can be excited to induce REM sleep.10 Cholinergic agents (anticholinestrases) such as donepezil, rivastigmine and tacrine are likely to increase the percentage of REM sleep, while cholinergic antagonists have a tendency to decrease REM sleep.11 Anticholinestrases affecting acetylcholine neuroreceptor system thus have a possible association with drug-induced nightmares. Memantine, which is a N-methyl-d-aspartate (NMDA) receptor antagonist, may cause surreal or unpleasant dreams, sometimes nightmares.2 Antidepressants Agents
All drugs that alter serotonin levels may affect sleep and dreaming. This effect is greatest for the monoamine oxidase inhibitors (MAOIs) followed by tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs).12 Intense visual dreaming and nightmares are associated with clomipramine; REM sleep rebound occurring after the withdrawal of these REM sleep suppressant agents.13 Fluoxetine, citalopram, as well as atypical antidepressant mirtazapine can also cause very peculiar, sometimes disturbing dreams.2 Antipsychotics Agents
Antipsychotic (neuroleptic) drugs e.g.; chlorpromazine, thiothixene and clozapine can increase vividness of dream but often decrease dream recall.2 Antiparkinsonian Drugs
Dopamine receptor stimulation may be another common mechanism resulting in drug-induced nightmares. Dopamine agonists - levodopa, bromocriptine, pergolide, amantadine, selegiline and rasagiline, used to treat Parkinson disease may cause vivid dreams, sometimes of sexual nature.14 Antiepileptic Drugs
Drugs known to affect the gamma-aminobutyric acid 659
Review ARticle (GABA) receptor (agonist, modulators and reuptake inhibitors) can cause nightmares and abnormal dreaming. Gabapentin, valproic acid and tiagabine are few examples related to GABA neurotransmitter. Other antiepileptics like lamotrigine and ethosuximide also cause dreams.15 Sedative Hypnotic Drugs
Nightmares and intense dreaming have been associated with the REM sleep rebound associated with withdrawal from REM sleep suppression agents-barbiturates. Benzodiazepines (diazepam, flunitrazepam, nitrazepam) and nonbenzodiazepine hypnotic, zolpidem can also induce dreams and night terrors by increasing REM sleep.16 General Anesthetic Agents
These agents may also induce nightmares. An increased incidence of pleasant dreams is reported with propofol use,17 while thiopental, midazolam, isoflurane and ketamine have been reported to produce disordered dreaming and nightmares.18 Antihistaminic Drugs
Chlorpheniramine has been reported to induce nightmares suggesting a potential role for histamine as a modulator of dreaming.19 Antimicrobial and Immunosuppressant Agents
Viral and bacterial infections can be associated with large increase in NREM sleep. In some studies, several agents like fleroxacin, erythromycin and ciprofloxacin, which are used for the treatment of bacterial infections, are reported to induce nightmares.19 Antiviral agents such as ganciclovir and amantadine may also lead to dreams. Even gusperimus, which is an immunologic response suppressant, is also reported to induce nightmares.7 Analgesic Drugs
People taking opioids as painkillers (morphine, buprenorphine) often report vivid dreams especially in the beginning of their use. Nonopioid pain killer, naproxen may also affect dreams.2 Endocrinal Agents
The hormones dehydroepiandrosterone (DHEA) and testosterone may cause nightmares if the dose is too large.2 660
Miscellaneous Drugs
Other drugs modulating the various neurotransmitters i.e., orexin, adenosine, histamine, glycine, glutamate, nitric oxide and neuropeptides may also be associated with varied dreams.20 Riluzole and dextromethorphan which are NMDA receptor antagonists may lead to unpleasant dreams, sometimes nightmares. Drug used for smoking cessation i.e., vareniciline which is a nicotine receptor partial agonist may also be responsible for nightmares.2 Herbal Drugs
Many herbal drugs influence dreaming, especially those with psychotropic effects like Kava-Kava, St. Johnâ&#x20AC;&#x2122;s Wort, Valerian, Licorice root, Jasmine, Lavender, Cardamom, Ginkgo biloba, Cinnamon, Marigold, Nutmeg, Peppermint and Passion flower. The Ayurvedic herb Ashwagandha is also well-known for creating surreal dreams.2 Drugs of Abuse and Dreams There are many drugs, such as opium, cocaine, cannabis, coal tar products and alcohol, which have an abuse potential, may have an influence upon dreams. Dreams caused by such drugs are, however, influenced by the physiological action of the drug taken, the amount used, the idiosyncrasies of the individual and the mentality. Drugs as opium and cocaine, when taken in medicinal doses, produce a sense of well-being and comfort and so tend to promote pleasurable fancies. These drugs, when taken in sufficient doses, cause sleep dreams which are not remembered. Many persons are much distressed by these drugs; and others, in place of awaking refreshed, awake tired and dimly conscious of disturbing dreams.21 CNS stimulant drugs e.g., amphetamines and caffeine may also lead to dreams. Amphetamines are associated with vivid and unpleasant dreams whereas caffeine has been used to induce lucid dreaming, because it makes one sleep lighter.22 Dreams are, thus, reflections of subconscious mind and are caused by a variety of pharmacological agents. These agents act via a variety of neurotransmitters i.e., adrenergic, cholinergic, dopaminergic, serotonergic and gabaminergic, etc. These drugs are either pharmacotherapeutic drugs prescribed for the treatment of various diseases or are the drugs of abuse. These drugs may be responsible Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011
Review ARticle for causation of dreams which are either pleasant in nature or may be in the form of nightmares. From the clinician point of view, various strategies can be adopted for the management of varied types of dreams especially nightmares and night terrors. Of foremost importance is the behavioral therapy. Nightmares and night terrors are usually disturbing to family members; therefore, proper diagnosis and education of family members are important components of management. Dreams disorders may respond to medication e.g., fluoxetine for posttraumatic stress disorder, clonazepam for night terrors3 and benzodiazepines for ketamine23 induced dreams but behavioral treatment approaches in the form of reassurance and support have shown excellent results, particularly in patients with post-traumatic stress disorder and recurrent nightmares. This therapy reduces the incidence of nightmares in about 70% of patients. If still the patient is not relieved, changing the suspect agent with a suitable alternative or withdrawal of the drug may help. Inspite of all the above mentioned treatment strategies, still, there is controversy as to what is the best option for the patient and thus research is going on to find the best approach.

Mucormycosis SA Kareem*, Valluvan**
Abstract Mucormycosis is one of the most aggressive fungal infections with very high mortality rate. Mucormycosis, also called â&#x20AC;&#x2DC;zycomycosisâ&#x20AC;&#x2122; is a serious and lethal invasive mycoses involving respiratory tract, gastrointestinal tract, skin and spreading to nearby structures like sinuses, orbit and brain. The spores of these fungi are inhaled. In poorly controlled diabetic patients and immunocompromised patients, the spores form hyphae and invade the surrounding tissues and blood vessels, leading to thrombosis and tissue necrosis. The black eschar of the palate is widely described as a hallmark of rhino-orbital mucormycosis. The angioinvasion of the retinal artery results in blindness, cranial nerve involvement, ptosis and later mass lesion resulting in proptosis. Proper management consists of treating the immunocompromised conditions, aggressive surgical debridement and aggressive antifungal therapy. Careful follow-up should continue for at least one year to confirm that there is no evidence of recurrent infection. Key words: Mucormycosis, apex syndrome, immunocompromised, antifungal treatment

ucormycosis is one of the most aggressive fungal infections with very high mortality rate. The list of immunocompromised patients is becoming long day-by-day, as they survive longer due to better treatment modalities. The treating doctors should have high degree of suspicion and skill to diagnose and manage these cases or else, in no time, this infection spreads to the brain. These cases may land in any department like Internal Medicine, Eye, ENT and Neurology depending upon the organs involved and extension. We are reporting two cases seen in our department with orbital apex syndrome due to mucormycosis.
Case Reports First case, a male patient aged 62 years, came with ptosis, diplopia, proptosis and pain left eye for past one week. He was a known diabetic patient for past 12 years, under oral hypoglycemic agents, on irregular treatment and poor glycemic control. On examination, vision right eye, 6/12 with pseudophakia, otherwise NAD, vision left eye no perception of light, ptosis with total ophthalmoplegia, with no corneal sensation and lens mature cataract. Other cranial nerves were normal.

Oral cavity examination showed palatal ulceration, with black eschar, with surrounding hyperemia. Mucormycosis was suspected and urgent CT scan was done. CT showed opacification and destruction of maxillary antrum with extension into the nasal cavity and orbit. ENT and neurosurgical consultations were done and clinical diagnosis of ororhino-orbital mucormycosis was made. The case was admitted and managed by a team of experts from Internal Medicine, ENT, Ophthalmology and Neurology. His diabetes mellitus (DM) was brought under control with insulin and antifungal oral itraconazole 200 mg b.i.d. PO was given. Amphotericin B, the first drug of choice could not be given, because his renal function showed abnormally high values. Aggressive surgical debridement of the palatal lesion, maxillary antrum and nasal cavity was done by ENT surgeon and histopathological examination showed Rhizomucor. He was under our treatment for 15 days, his proptosis became less and DM was controlled well. As he was showing good improvement, he wanted to go home because of some urgent personal problem and promised to come back after his family problem was over. But he did not come back. The second case was a female patient aged 65 years who presented with headache, proptosis and ptosis for past five days. She was a known patient of DM for past 12 years, under oral hypoglycemic agents, irregular in treatment and poor control of blood sugar. Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011

Discussion Mucormycosis, also called â&#x20AC;&#x2DC;zycomycosisâ&#x20AC;&#x2122; is a serious, aggressive and lethal invasive mycoses involving respiratory tract, gastrointestinal tract, skin and spreading to nearby structures like sinuses, orbit and brain. Mucor is not the most common, rather 663
Case Report Rhizomucor are the genera usually present in these patients. The spores of these fungi are found in the soil and, usually nonpathogenic. They are inhaled and in normal persons, the spores are prevented to germinate into hyphae by alveolar macrophages. In poorly controlled diabetic patients and immunocompromised patients, the spores form hyphae and invade the surrounding tissues and blood vessels, leading to thrombosis and tissue necrosis. In this devitalized tissue, the hyphae continue to grow and angioinvasion gives rise to black eschar. The black eschar of the palate is widely described as a hallmark of rhinoorbital mucormycosis. The angioinvasion of the retinal artery results in blindness, cranial nerve involvement, ptosis and later mass lesion resulting in proptosis. The infection further progresses into the brain resulting in the formation of brain abscesses. Proper management consists of treating the immunocompromised conditions, aggressive surgical debridement and aggressive antifungal therapy. Careful follow-up should continue for at least one year to confirm that there is no evidence of recurrent infection. Conclusion Mucormycosis cases, even though appear to be rare now, are bound to be more common in the future due to various causes like high incidence of diabetes, AIDS,
organ transplantation, radiotherapy and chemotherapy. These cases may come to any specialty depending upon the organs involved. Proper clinical examination and suspicion, especially in immunocompromised patients can save the life of the patients. Suggested Reading 1. Liang KP, Tleyjeh IM, Wilson WR, Roberts GD, Temesgen Z.

Case Report Discussion Holt-Oram syndrome was discovered by Mary Holt and Samul Oram in 1960. Clinical features of Holt-Oram syndrome vary depending upon the severity of cardiac and limb malformations. Musculoskeletal Defects
Figure 1. Inspection of the body revealed findings suggestive of Holt-Oram syndrome.
Upper limbs are usually affected. Although bilateral, the left side is more commonly affected. The most severe form is phocomelia with rudimentary limbs. Mildest forms include clinodactyly, limited supination and sloping shoulders. The most common defects include radial thumb anomalies ranging from absent thumbs to displaced duplicated or triphalangeal thumbs. Hypoplasia of the radius manifests as short deformed forearm. Sprengel deformity (upward displacement of the scapula) and hypoplasia of the shoulders and clavicles may also be present. Associated muscular hypoplasia involves the hypothenar, wrist extensor, supinator, biceps brachii and triceps brachii. Heart Defects
X-ray of spine - hemivertebra (Fig. 2)
X-ray of chest - normal
The reported incidence ranges from 50 to 95%. The most common lesion is a secundum atrial septal defect. Other lesions include ventricular septal defect, atrioventricular block (AV block), pulmonic stenosis and mitral valve prolapse. Approximately 17% of patient have more complex cardiac malformations, such as tetralogy of Fallot, hypoplastic left heart, endocardial cushion defect and truncus arteriosus. Cardiac arrhythmias including paroxysmal tachycardia, prolonged PR interval, wandering atrial pacemaker, atrial ectopics, AV block and sinus bradycardia may be present. According to Mglinets, a specific feature of the syndrome is a changes in the main palmar lines and their termination on the radial border of the hand. Pulmonary hypoplasia has occasionally been reported and can present with neonatal respiratory distress.

Pathophysiology
Defective development of the embryonic radial ray (aplasia, hypoplasia, fusion) results in a wide-spectrum of phenotypes, including triphalangeal or absent thumb, foreshortened arms and phocomelia. The syndrome is associated with defective development of cardiac structures that results in atrial septal defect, most commonly, secundum type; heart block of varying degree or both. The responsible gene has been mapped to band 12q 24.1, which encodes the human transcription factor TBX-5. One of the recently added loci is c.373 G > A, with results in the missense mutation p.Gly125 Arg, a novel mutation. A cardiomelic developmental field has also been postulated to relate the genetic heterogeneity of Holt-Oram syndrome, to a cascade of molecules, including the brachyury, sonic hedgehog homolog, bone morphogenetic protein,

Biopsy of Skin Diseases in Urban and Suburban Population Amar Ranjan
Abstract Objective: To highlight the importance of histopathology in clinical practice of skin diseases specially in developing countries. Study design: Data of skin biopsy cases collected retrospectively (of previous years). It was analyzed in terms of number and kinds of cases which required skin biopsy for diagnosis and differential diagnosis. Result: Seventy percent of biopsy cases correlated with 2-4 provisional diagnoses given by the clinicians. Rest 30% couldn’t be diagnosed with confirmation, which needed follow-up. It showed mostly cases of psoriasis, lichen planus, leprosy and tuberculosis in decreasing order. Conclusion: Promotion of skin biopsy practices will improve the diagnostic accuracy in dermatology practices. Key words: Skin diseases, urban population, suburban population, developing countries
S
kin diseases have only recently been considered as a possible health problem in developing countries. Data supporting this issue is sparse. The available data are mostly on the clinical ground. The general concept in the developing countries about the skin diseases is ‘it is incurable and the patient has to visit the doctor frequently’. And, this is a costly affair in terms of money, time and labor. Drugs used in dermatological practice are costly and are taken for longer duration and/or at frequent intervals. Such kind of concept of general population needs to be taken seriously and trial must be done to ameliorate it. This study has tried to improve the diagnostic accuracy by using different diagnostic modalities in dermatological practice specially ‘skin biopsy’. This study specially presents a report of the experience of a superspecialized dermatological center in New Delhi, India, which has a well-equipped histopathology center.
Material and Methods This study has been conducted in a superspecialized hospital of skin diseases in Delhi. This study has been conducted from the data of skin biopsy cases done from August 2003 to February 2004 (seven months)

retrospectively. Cases for skin biopsies were received in the laboratory, which were sent by 8-10 different dermatologists working at the center. The cases were mainly from Delhi and NCR, as this hospital has two subcenters in Delhi and NCR. Some cases were also referred from different cities of other states in India. Cases were of all age group and of both sexes. We received the prescribed form with brief of clinical presentation and 2-4 provisional diagnoses. It is obvious that the cases which were clinically diagnosed accurately by the dermatologists alone and responded well by drug therapy, were not sent for histopathological examination (HPE). We in the laboratory, examined the case and investigated according to the need of the patient and as advised by the clinicians. We did hematological, biochemical and serological investigations. We did special tests for skin diseases as Tzanck smear, India ink preparation, KOH preparation, skin smear examination and Wood Lamp examination. We also used dark ground microscopic examination of smears for the diseases pertaining to Spirochete group. We lastly came to skin biopsy for HPE. We did ‘punch biopsy’ using disposable punch blade measuring 0.5 × 0.5 cm size (length and diameter). Punches were made by taking the inflamed skin together with normal one. Tissues were processed and routine hematoxylin and eosin (H&E) staining was done. It was examined by light microscopy. The final HPE report was made by the same histopathologist. The second opinion was taken by a Dermatopathologist working at the center whenever needed. In most of the cases provisional 669
Clinical study diagnoses given by the dermatologists correlated well with the clinical diagnoses. Histopathologist also suggested possible diagnoses to the dermatologists (clinicians) after looking at the histopathological picture wherever it was possible, i.e., there was a good correlation between the pathologist and the clinicians. All the biopsy specimens were examined by using routine H&E stain. Special stains were done wherever needed. These are Verhoeff-Van Gieson stain and Periodic Acid-Schiff stain for collagen fibers, Zeihl-Neilsen stain for tuberculous and lepra bacilli. Serial sectioning was also done wherever required. Special cases were confirmed by immunofluorescence technique as well. Results We performed skin biopsies of total 622 cases. It was noticed that out of 622 cases, in 430 (69.2%) cases, the histopathological report matched well with any one of the provisional diagnoses given by the clinicians. This figure included the diagnoses suggested by the dermatologist to the pathologist or vice versa. In the rest 192 cases (30.8%), provisional clinical diagnoses couldn’t be correlated with histopathological report. In the cases where the diagnosis couldn’t be made either clinically or histopathologically, was reported as ‘Descriptive’. This study has focused over the diagnosed cases histopathologically as well as clinically. The important skin diseases are shown in Table 1. Discussion It has been noted that a large number cases in dermatological practices need confirmation by histopathology. As in this case, clinicians put 2-4 provisional diagnoses. In approximately 70% of cases any one of the provisional diagnoses were confirmed by HPE. The rest 30% cases couldn’t be confirmed. These cases were kept under close follow-up. Reason behind these undiagnosed cases may be the partial treatment of the cases, which may have morphed the lesion. Secondly, the disease may be in early or late stage. As the tertiary care center received a number of referred cases. So, there is the possibility that they had been already treated by dermatologists in their primary 670
phase of treatment. Now, we look at the diagnosed cases. Current study (based on biopsy) has been summarized in Table 2. Similar kind of study was conducted in a Karnataka village area by Kuruvilla1 et al in 1997, which has been shown in Table 3. In the current study (Table 2), psoriasis and lichen planus top the list where as the Table 3 shows these two as minor problem. This is because the skin diseases have been categorized on the basis of clinical diagnoses mainly. Biopsy was also done in the required cases in this study as well. Our study reflects the cases, which were sent for HPE only. Clinically diagnosed cases or cases diagnosed by minor noninvasive procedures e.g. Tzanck smear; were excluded from our study. Like scabies can be diagnosed on history and clinical ground only. Study from rural area of Assiut Governorate, Upper Egypt (AbdelHafez3 et al 2003) gave data (in descending order of prevalence), which have been shown in Table 4. This data is more or less similar to the findings of Table 3, as eczema and fungal infection top the list. The increased incidence of pigmentary lesions and nevoid diseases may be due to racial and geographical variation in the pattern of skin diseases. Infectious diseases are directly associated with personal hygiene, socioeconomic status and overcrowding. Data, form a study conducted at University Teaching Hospital, Addis Ababa, Ethiopia by Shibeshi6 in 2000, has been shown (in descending order of prevalence) in Table 5. As marked in data, most of the allergic and infectious diseases do not need biopsy and are made on clinical ground as well as by hematological and biochemical investigations e.g., IgE level, C-reactive protein and ESR, etc. Data from another study conducted in a hospital in southwestern Saudi Arabia (Shelleh2 et al 2000) has been shown (in decending order of prevalence) in the Table 6. Most of the cases in this study is based on clinical diagnoses considering age, history of contact, etc. Pattern of skin diseases in Imphal, India, studied by Devi7 2006 has been shown in Table 7. This study is also based on clinical diagnoses. Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011

Diagnoses are based on clinical ground in developing countries like India and skin disease is a major health problem. A general conception is that there is no permanent cure of skin disease. Only selected patients visit the dermatologist. Dermatologists make a diagnosis clinically and try to cure. Blind trial of the drugs results in long-term treatment and treatment costs are high. Even after that a satisfactory result is usually not obtained. General histopathologists have difficulty in diagnosing dermatological diseases. In India, there is 671

no separate specialization for dermatopathology. Whereas in developed countries there is superspecialized branch of dermatopathology. As per author’s search on internet for articles on skin diseases based on skin biopsy, no literature is available. This kind of study may provide some hidden findings in the field of dermatology. If, we move on to better diagnostic techniques like skin biopsy, the number of diagnosed cases will 672

improve and finally cure rates will increase. This study shows approximately 31% of diagnostic failure even after practice of skin biopsy. So, it can be assumed that what will be the percentage of diagnostic failure for the dermatologists who don’t use skin biopsy for diagnosis. The commonly used skin biopsy technique is ‘punch biopsy’, which is an outdoor procedure and doesn’t need any kind of anesthesia. This can be easily be performed by dermatologists himself. However, it is not practiced much in our country. Summary Lichen planus and psoriasis are an important health problem in India. They both need skin biopsy for correct diagnosis.

To promote dermatopathological practices by dermatolosists as well as by histopathologists. To provide knowledge of dermatopathology to postgraduate students at institutional level. In the condition of unavailability of dermatopathologist, dermatologists must keep in mind the pattern of skin diseases in our country. Pattern of skin diseases are different in India in comparison to other countries as shown by the articles published in journals. A close correlation between pathologist and dermatologist can give better results.

AAP Reports on Use of Probiotics and Prebiotics in Children
I
n recent years there has been increased interest in adding probiotics and prebiotics to nutritional products to optimize intestinal microflora. However, as with antibiotics, the use of these supplements should be supported by evidence-based medicine. The American Academy of Pediatrics (AAP) recently reviewed the medical uses of probiotics and prebiotics to help guide physicians in counseling parents about the use of these products as dietary supplements added to foods for children, including infant formula. Infants have sterile gastrointestinal tracts at birth, but bacterial colonization occurs rapidly. Gestational age, mode of delivery, and diet seem to have significant effects on this process. Dysregulation of the intestinal mucosal defense system early in life is believed to be a factor in many chronic conditions, such as atopic diseases (e.g., asthma, eczema, allergic rhinitis) and autoimmune diseases (e.g., multiple sclerosis, type 1 diabetes mellitus, chronic inflammatory bowel disease). Because of their influence on intestinal microflora colonization and immune function, an infantâ&#x20AC;&#x2122;s early diet and intestinal microbial environment are thought to be pivotal factors in his or her overall health. Probiotics Probiotics are supplements containing organisms that change the microflora of the host. These organisms are typically Lactobacillus, Bifidobacterium, and Streptococcus species. They are able to predominate and prevail over potential pathogenic microorganisms in the human digestive tract, and are thought to produce metabolic byproducts that function as immune modulators. As of December 2010, at least two infant formulas that contained probiotics were being sold in the United States. One contained Bifidobacterium lactis, and the other contained Lactobacillus rhamnosus GG (LGG). The addition of probiotics to powdered infant formula Source: Adapted from Am Fam Physician. 2011;83(7):849-852.
676
has not been proven harmful to healthy term infants. However, there is no evidence of clinical effectiveness, and the routine use of these formulas is not recommended. No studies have compared the health benefits of using these formulas versus breastfeeding. Probiotics should not be given to children who are seriously or chronically ill until the safety of these products has been established. The optimal duration of probiotic supplementation is not known, nor is the optimal dosage or species. The long-term effects on intestinal microflora in children also are not known. Acute Infectious Diarrhea
The use of probiotics early in the course of diarrhea from acute viral gastroenteritis may reduce its duration by one day in otherwise healthy infants and young children. This benefit is strain-dependent; LGG is the most effective probiotic reported. However, the evidence does not support the routine use of probiotics to prevent infectious diarrhea unless there are special circumstances (e.g., in child care centers). The use of the new pentavalent rotavirus vaccine will likely be more effective than the use of probiotics in preventing the most common form of acute infectious diarrhea in infants. Antibiotic-associated Diarrhea
There is some evidence to support the use of probiotics to prevent antibiotic-associated diarrhea, but there is no evidence that it is effective for treatment. LGG, B. lactis, Streptococcus thermophilus, and Saccharomyces boulardii were the most common probiotics used in randomized controlled trials (RCTs). There have been no RCTs examining the effects of probiotic use in children with Clostridium difficile antibiotic-associated diarrhea. Atopic Diseases
The intestinal bacterial flora of children with atopic disease has been proven to have more Clostridium and Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011
practice guidelines fewer Bifidobacterium organisms than that of children without atopic disease. For this reason, it has been hypothesized that the administration of probiotics to infants at risk of atopic disease—particularly those who are formula fed—would be beneficial. There is some evidence supporting the prophylactic maternal use of probiotics during pregnancy and the continuation of therapy in the mother and infant during lactation, but further studies are needed. Probiotic use has not been proven effective in the treatment of eczema. Necrotizing Enterocolitis
Preterm infants often have delayed and aberrant acquisition of normal digestive microflora, possibly because of restricted enteral feedings and frequent administration of antibiotics. These factors are thought to contribute to an increased risk of necrotizing enterocolitis in preterm infants. There is some evidence to support the use of probiotics in very low-birthweight infants (birth weight of 1,000 to 1,500 g [2 lb, 4 oz to 3 lb, 5 oz]). However, the amount and specific type of probiotic are difficult to determine. Chronic Inflammatory Bowel Disease
It is estimated that up to 70 percent of children and adults with chronic inflammatory bowel disease (i.e., Crohn disease or chronic ulcerative colitis) routinely use complementary and alternative medicine, including probiotics, as adjunctive or replacement therapy for prescribed medications. Theoretically, probiotics may be beneficial in the treatment of these conditions. However, the long-term benefit of using probiotics to treat Crohn disease requires further study and is not recommended in children. The results of RCTs in which probiotics were used to treat chronic ulcerative colitis are encouraging, but require further confirmation.
Other Conditions
The sustained or long-term benefit of using probiotics to treat disorders such as irritable bowel syndrome, constipation, and extraintestinal infections requires further study; currently, use is not recommended in children. There is some evidence that probiotics may be beneficial in treating children with Helicobacter pylori gastritis and infantile colic; however, further study is needed before recommendations can be made. Probiotics have not been proven beneficial in treating or preventing cancer. There are safety concerns with the use of probiotics in infants and children who are immunocompromised, chronically debilitated, or seriously ill and who have indwelling medical devices. Prebiotics Prebiotics are supplements containing a nondigestible ingredient—usually in the form of oligosaccharides— that selectively stimulates the favorable growth or activity of indigenous probiotic bacteria. Although prebiotics are indigestible, their presence in the digestive tract enhances the proliferation of probiotic bacteria in the colon, especially Bifidobacterium species. Human milk contains substantial quantities of prebiotics and is preferred for infants up to six months of age. The addition of oligosaccharides as prebiotics to infant formula is not unreasonable, but lacks evidence showing clinical effectiveness. It is not known whether their use is cost-effective. The use of prebiotics in preventing or treating diseases in children has not been tested extensively in RCTs, but the available evidence shows that there may be some long-term benefit for the prevention of atopic eczema and common infections in healthy infants. However, confirmatory studies, especially in children who are given formula that is not partially hydrolyzed, are needed before recommendations can be made. n

Research Review
From the Journals ...
Valsartan may Decrease the Incidence of Diabetes Mellitus Background: Several trials have reported that inhibiting the renin-angiotensin system (i.e., with angiotensin-converting enzyme [ACE] inhibitors or angiotensin receptor blockers [ARBs]) may prevent patients with hypertension or other cardiovascular disease from developing diabetes mellitus. However, this effect was not a primary outcome of most trials, and results were not confirmed by systematic glucose measurements. McMurray and colleagues used the NAVIGATOR (Nateglinide and Valsartan in Impaired Glucose Tolerance Outcomes Research) trial to study the effectiveness of ACE inhibitors and ARBs at reducing the risk of diabetes and cardiovascular events in patients with impaired glucose tolerance. The Study: Investigators randomized 9,306 patients to receive valsartan in dosages of 80-160 mg daily or placebo. All patients participated in a lifestyle intervention program designed to reduce the risk of diabetes. In addition to having impaired glucose tolerance, all eligible participants had preexisting cardiovascular disease or at least one risk factor for cardiovascular disease. Exclusion criteria included the use of antidiabetic medications within the previous five years, or the use of an ACE inhibitor or ARB for hypertension. Three coprimary outcomes were evaluated: the incidence of diabetes; a composite cardiovascular outcome including development of heart failure, nonfatal myocardial infarction or stroke, unstable angina, arterial revascularization, or cardiovascularassociated death; and a similar composite cardiovascular outcome that excluded unstable angina and the need for revascularization. Results: Diabetes was less likely to develop in the valsartan group than in the placebo group (33.1 versus 36.8 percent, respectively; hazard ratio = 0.86). Fasting and two-hour postload glucose levels were also lower in the valsartan group (â&#x2C6;&#x2019;0.59 mg per dL [0.03 mmol 678
per L] versus â&#x2C6;&#x2019;3.15 mg/dL [0.17 mmol per L] in the placebo group). However, cardiovascular outcomes remained similar between the groups (14.5 versus 14.8 percent for placebo). Conclusion: The authors conclude that valsartan therapy (in a dosage up to 160 mg daily) reduces the likelihood that patients with impaired glucose tolerance will develop diabetes (relative risk reduction = 14 percent). This translates into roughly 26 patients needing to be treated for five years to prevent one new case of diabetes. However, valsartan does not reduce the risk of cardiovascular events.

Probiotics vs Antibiotics to Treat Lactation-associated Mastitis Background: Mastitis affects up to 33 percent of lactating mothers and is a common reason why women stop breastfeeding. It can also be difficult to treat because of its polymicrobial nature. Several strains of lactobacilli have shown promise as probiotic agents that might be useful in treating mastitis. Arroyo and colleagues compared the effectiveness of probiotic and antibiotic therapies in women with lactationassociated mastitis. The Study: A total of 352 women with mastitis symptoms were randomized to receive one of three treatments: a daily capsule with 200 mg of a freezedried probiotic containing 9 log10 colony-forming units (CFUs) per mL of Lactobacillus fermentum (CECT5716), a similar amount of Lactobacillus salivarius (CECT5713), or an antibiotic prescribed by their physician. Patients were followed for 21 days, with pain scores and breast milk samples obtained at the beginning and end of the study. All patients had breast inflammation, painful breastfeeding, and initial milk bacterial counts of more than 4 log10 CFU per mL. Women with mammary abscesses, Raynaud syndrome, or any other breast-related pathology were excluded. Results: Initial pain scores and bacterial counts were similar among the three groups. The three most Indian Journal of Clinical Practice, Vol. 21, No. 12, May 2011
Research Review common bacterial species identified were Staphylococcus epidermidis, Staphylococcus aureus, and Streptococcus mitis in statistically similar proportions among groups. By day 21, a greater bacterial reduction occurred in women receiving probiotics compared with antibiotics, with the greatest reduction in the L. salivarius group. Breast pain scores were also significantly lower in the probiotic groups, with complete recovery in 88 percent of the L. fermentum and 85 percent of the L. salivarius group by day 21, compared with 28.7 percent of the antibiotic group. Recurrence of mastitis was also significantly more common in the antibiotic group than in the L. fermentum or L. salivarius group (30.7, 10.5, and 7.1 percent, respectively). Conclusion: The authors conclude that L. fermentum or L. salivarius is an effective alternative to antibiotics for the treatment of infectious mastitis during lactation. Am Fam Physician. 2011;83(3):311-316.
Early vs Delayed Treatment of Anterior Cruciate Ligament Tears Background: An anterior cruciate ligament (ACL) tear is associated with joint instability, decreased activity, and an increased risk of developing osteoarthritis of the knee. Although treatment usually involves early surgical reconstruction combined with physical therapy, it is unclear whether this improves clinical outcomes. Frobell and colleagues performed a randomized controlled trial to determine if rehabilitation with early ACL reconstructive surgery was more effective than rehabilitation with delayed ACL reconstructive surgery.
The Study: The authors recruited 121 healthy persons 18 to 35 years of age presenting with a new ACL injury to participate in the Knee Anterior Cruciate Ligament, Non-surgical versus Surgical Treatment Study. All participants received physical rehabilitation, but were randomized to receive early ACL reconstructive surgery within 10 weeks postinjury, or to be monitored for up to two years with the option for ACL repair surgery if they remained symptomatic. Persons with total collateral ligament rupture and full-thickness knee cartilage lesions were excluded. The primary outcome was the change from baseline to two years in the average Knee Injury and Osteoarthritis Outcome Score regarding pain, symptoms, difficulty in sports and recreational activities, and quality of life. Results: Of the 59 participants in the delayed reconstruction group, 23 ultimately received ACL reconstructive surgery an average of 11.6 months after randomization. Both groups showed similar clinical improvement, with no significant differences in the score between groups during the two-year period. No differences were noted between groups regarding kneerelated outcomes or the return to preinjury activity levels. Conclusion: The authors conclude that for acute ACL tears in young, active adults, structured rehabilitation with optional delayed reconstructive surgery results in similar clinical outcomes compared with an early ACL repair strategy. In this study, surgery was avoided in 61 percent of the delayed reconstruction group, without adversely affecting outcomes. Am Fam Physician. 2011;83(7):842-844.

Biomarker Predicts Colon Cancer Survival in Obese Patients A protein biomarker may predict better chances of survival for obese patients with colorectal cancer, but the biomarker held no prognostic value for nonobese patients, researchers found (April 27 issue of the Journal of the American Medical Association). Patients with a body mass index of 30 kg/m2 or more were 76% less likely to die from colorectal cancer when positive for cadherin-associated protein beta-1 (CTNNB1 or betacatenin, p < 0.001 for interaction) in analysis of nearly 1,000 prospectively-followed patients. Antifibrotic may Slow Diabetic Nephropathy Diabetic nephropathy may not just slow but may actually improve with the novel antifibrotic agent pirfenidone, researchers found in a preliminary study. Kidney function continued to drop in diabetic kidney disease patients without treatment, but rose significantly with a low-dose of pirfenidone over one year, Kumar Sharma, MD, of the University of California San Diego and VA Medical Center in La Jolla, Calif., and colleagues reported online in the Journal of the American Society of Nephrology. Some Benefit Seen for Ovary Removal at Hysterectomy Removing the ovaries at the same time as the uterus made a small risk of subsequent ovarian cancer even smaller without significantly increasing other risks, results of a large observational study showed. Breaking News: Person Revived after 96 Minutes of CPR A 54-year-old man with post-MI ventricular fibrillation regained spontaneous circulation after a dozen defibrillator shocks and continuous CPR for 96 minutes with full physical and neurological recovery reports Dr Roger D White at the Mayo Clinic in Rochester, Minn in a case report published online April 20 in the Mayo Clinic Proceedings. 680
The patient was resuscitated for initial 31 minutes by the emergency staff along with DC shocks. At the 31st minute a helicopter transport crew arrived and continued applying defibrillator shocks to the man who did not have a pulse, yet showed signs of systemic blood flow as measured by an end-tidal carbon dioxide sensor. The team administered a total of 12 defibrillator shocks and kept the patient’s blood flowing with continuous chest compressions. A key piece of technology on the scene was capnography, which measures how much blood is flowing through the lungs and subsequently to other organs. Capnography has been used to monitor patients in operating rooms but is not often used by ER when treating cardiac arrest. As the measurement remained sufficiently high, the rescuers were encouraged to continue resuscitation efforts. At the hospital, he was stabilized and taken to the cath lab and was stented for 100% occlusion in the mid-left anterior descending coronary artery. The persistent low blood pressure was stabilized with an intra-aortic balloon pump (IABP). The patient was discharged after 10 days with no neuro damage. Lessons Learned
It’s the only case where a person has been revived after 96 minutes of clinical death. We had a similar case where CPR was continued for 45 minutes. GB Pant reports a similar case with revival after an hour and with stenting (Dr Vijay Trehan) Medicolegal implications: Do not stop resuscitation for upto 100 minutes and make sure you measure E tube CO2 levels Transport the patient to nearest cardiac hospital for possible angiography and IABP, if required.

Young Indian Adults Developing more Risk Factors for Heart Disease Increasingly, young adults residing in urban areas of India are developing hypertension, obesity and diabetes, which suggests that the country may soon experience an increase in heart disease rates, according to a study published in the Journal of the American College of Cardiology. Higher Death Rates Seen in Kidney Failure Patients through Central Line Catheter Ass per the American Society of Nephrology wrote, Patients on peritoneal dialysis (PD) typically have a higher early survival rate than patients on hemodialysis (HD). New data suggest that this difference may be explained by a higher risk of early deaths among patients undergoing HD with central venous catheters, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology. Access Type may Impact Hemodialysis Patient Survival Central venous catheters may account for the poorer survival among HD patients, according to an analysis, which included 40,526 adults, in the Journal of the American Society of Nephrology. Use of a central port for dialysis was associated with 80% elevated one-year mortality risk compared with PD, the researchers found. An Inspirational Story Reach for Your Star

WHO Warns of Enormous Burden of Chronic Disease Chronic illnesses like cancer, heart disease and diabetes have reached global epidemic proportions and now cause more deaths than all other diseases combined, the World Health Organization (WHO) said on Wednesday. In its first worldwide report on so–called noncommunicable diseases, or NCDs, the United Nations health body said the conditions caused more than half of all deaths in 2008 and pose a greater threat than infectious diseases such as malaria, HIV and tuberculosis (TB) - even in many poorer countries. NCDs, which include heart disease, lung diseases, cancer and diabetes, accounted for 36 million or 63%, of the 57 million deaths worldwide in 2008. Millions of lives could be saved and much suffering avoided if people did more to avoid risk factors like smoking, drinking and being overweight, the WHO said. First Autologous Organ The race is on to build the first complex organ. Describing what it will take to achieve this momentous milestone was Doris Taylor, PhD, Director of the Center for Cardiovascular Repair, Medtronic Bakken Professor of Integrative Biology and Physiology, and Professor of Medicine at the University of Minnesota, during Monday’s State-of-the-Art Address, ‘Rebuilding Autologous Organs: Cells, Scaffold, Organ.’ Rebuilding an organ involves collecting appropriate types and numbers of cells, selecting the right scaffold, decellularizing the scaffold and seeding the scaffold with the cells. When this concept works, the end result is an organ that performs its appropriate function (American Transplant Congress, 2100). 681
emedinews Section Neglect, Under Treatment Ails Headache Disorders Three in every four adults, aged between 18 and 65, suffered from some form of headache disorder, including migraine and tension-type headaches, last year. WHO says headaches are the most common health disorders across the world, but they are often neglected and under-treated. According to the world’s first ‘Atlas of Headache Disorders 2011’ brought out by the WHO, 50% suffering from headaches opt for self-medication, oblivious to bouts of pain. Neurologists examine only 10% headache patients, and the rate is even lower in Africa and South-East Asia. The report says, over 10% of those suffering frequent headaches have migraine, and 1.7-4% of the adult population is affected by headache for 15 or more days every month. Information on the societal impact of headache exists in only 18% of countries that responded for the report. Three types of headache disorders have been underlined as most frequent - migraine, tensiontype and those caused by medication-overuse. —Source: TOI, May 5, 2011

General - Fit Facts and Tips for Specific Populations
Regular physical activity reduces the risk of many adverse health outcomes. Some physical activity is better than none. For most health outcomes, additional benefits occur as the amount of physical activity increases through higher intensity, greater frequency and/or longer duration. Most health benefits occur with at least 150 minutes (2 hours and 30 minutes) a week of moderate-intensity physical activity, such as brisk walking. Additional benefits occur with more physical activity. Both aerobic (endurance) and musclestrengthening (resistance) physical activity are beneficial. Health benefits occur for children and adolescents, young and middle-aged adults, older adults and those in every studied racial and ethnic group. The health benefits of physical activity occur for people with disabilities. The benefits of physical activity far outweigh the possibility of adverse outcomes.
Pediatric Update What is the Classical Presentation of Appendicitis in a Child?
Pain begins in periumbilical or epigastric region, due to appendiceal distension and referred pain. Pain localizes to the RLO as the parietal peritoneum in the area becomes irritated. Anorexia and nausea occur almost uniformly after the pain.
The classical presentation occurs in only 50% of patients. —Dr. Neelam Mohan, Director, Pediatric Gastroenterology, Hepatology and Liver Transplantation, Medanta – The Medicity

igh doses or long-term use of PPIs or proton-pump inhibitors can lead to an increased risk of bone fractures. This holds especially true for those over the age of 50, and for people on the high dose. The latest warning is based on a FDA review of several studies of the treatment. These epidemiologic studies revealed an elevated fracture risk at the hip, wrist and spine. But the studies do not, definitively prove that PPIs are the cause of the fractures.
www.ijcpgroup.com
FDA has instructed the manufacturers of the drugs to change the labels for both the prescription and the over-the-counter versions of the PPIs. The FDA said they should only be taken for 14 days to help ease frequent heartburn and under no circumstances should over-the-counter PPIs be taken for more than three 14-day periods in a year.
Asian Journal of
Ear, Nose Throat
Most researchers believe that more fractures are due to decreased calcium absorption from the diet because of the reduced stomach acid. But, it’s also possible that these drugs interfere with bone maintenance. Notably, PPIs have previously been linked to an increased risk of contracting pneumonia and the troublesome bacterium Clostridium difficile, as well as to an increased risk of dementia.

iddle-aged women who move around more in their daily life have lower levels of intra-abdominal fat, a risk factor for heart disease. Minor modifications in daily routine such as reducing the time watching TV or increasing the walk time to work, can make a difference in the long-term health. Visceral fat is a hot topic because of metabolic syndrome, which predisposes people to disease. Intra-abdominal fat, or the fat that wraps around the organs in the abdomen and chest, tends to accumulate at midlife and can contribute to developing diabetes, hypertension and heart disease. The fat around the organs is known to be more related to heart disease and diabetes. A woman does not need to appear outwardly heavy to have a potentially troublesome extra ‘tire’ around her organs. Exercise for long has been known to reduce the amount of intra-abdominal fat.
