Dear readers,
LETTER FROM THE EDITORS
Welcome to the fourth edition of The Medical Decoder (MD). As Editors-in-Chief of this rapidly growing publication, we wanted to take the time to reflect upon the whirlwind journey that has culminated in the great success of this journal. The MD was founded just over a year ago by three pre-medical students with a vision and a Microsoft Word document. This vision was a powerful one: to help busy students stay aware of the changes occurring in the fields of medicine and health care and to provide an outlet to share concerns, passions, and experiences. The Word document was less impressive; the first draft employed uninspired fonts and simple Clip Art. As often happens with new ideas, translating our original vision to a reality took time, patience, and hard work. However, the most pleasant realization along this journey was that our vision was a shared one; students were excited to get involved on all fronts, whether through writing, editing, designing, or just spreading the word. Throughout the development of the MD, we have learned that when a diverse group of students shares a vision, they can empower each other to generate a voice that resonates louder than any one could have individually. As students who plan on entering health-related fields, it is important to express ourselves and connect with others who have similar aspirations. Learning more about our fields and keeping up with contemporary medical practices through easyto-read and engaging articles empowers us to “decode” information related to health care. This will allow us to become better leaders and doctors in the future. As the world around us continues to change, it is crucial that we fully understand the fields that we will be entering, continue to share our concerns, and advocate for change when it is necessary. This fourth installment of The Medical Decoder will be the last edition for both of us as Editors-in-Chief. It has been a joy to see how this publication has grown, and we are very excited to see where the next Editors-in-Chief will take the journal. Thank you for your continued interest in our publication. Your support over the past year has been vital to our success, and we greatly appreciate your help in spreading our message. On behalf of Phi Delta Epsilon IL Gamma as well as the rest of the MD team, we would like to welcome you to the fourth edition of The Medical Decoder.
Sincerely, Aditya Ghosh & Sarah Smith

physicians see around 100 patients per week, and many see thousands of patients annually.4 Therefore, it is imperative that doctors practice what they preach, not only so that patients will heed their medical advice, but also to serve as role models. Physicians, however, are only human. With lengthy shifts and packed schedules, it is understandable why they may occasionally overlook their own health. One of the best examples of this can be seen during a doctor’s residency. Second-year residents can work for up to 28 consecutive hours.9 This workload, along with expensive student loans and a salary averaging at about $50,000, can limit both the time and resources one needs to maintain a healthy lifestyle.10 These factors also contribute to stress. One physiological response to long-term stress is
the release of cortisol, which can lead to excess fat accumulation over extended periods of time.11 This added weight could put a physician at a risk for a slew of chronic diseases, just as it could for his or her patients.1 As we continue moving forward with wellness initiatives in health care, it is necessary that the next generation of doctors is mindful of maintaining healthy lifestyles. There is also an important takeaway for patients: busy work hours, salary, and stress are all contributing factors to why certain physicians may fail to follow healthy behaviors. Like many sensitive issues, the importance of physicians practicing what they preach has two sides. Patients should acknowledge the importance of following their doctors’ recommendations regardless of their doctors’ physical appearance. Additionally, physicians must also recognize the negative impact that their actions can have, and their potential to inspire positive behaviors in their patients by leading healthy lifestyles.

Early Intervention for Autism Treatment By Sarah Laudon
A
utism spectrum disorder (ASD), according to the Centers for Disease Control (CDC), is a group of developmental disabilities that can cause significant social, communicative, and behavioral challenges.1 These challenges can range from difficulty maintaining a conversation or eye contact with somebody to struggling with transitions to new things. Autism contains a wide spec-
trum of symptoms that often comes with co-diagnoses of developmental, psychiatric, neurological, chromosomal and genetic conditions.1 Because ASD covers a vast array of conditions and symptoms, multiple fields including pediatrics, primary care, psychology, and neurology are involved in the treatment of this disease. Therefore, it is all the more important that future health care providers become cognizant of this disorder and its available therapies. Human Interest ■ Volume 4 ■ Fall 2014 ■ 9

Providing the students

with something that they want increases the likelihood that these behaviors will continue.2 All therapy at the RCA is performed with one therapist and one student paired together during the day. The training process for therapists at the RCA is intensive. Before a therapist and child are paired together, the new therapist must spend several days shadowing an experienced staff member, playing with the child, observing all academic programs and behaviors, and learning the behavior plans. When the new therapist is ready, he or she is observed by a trained therapist and given constructive feedback. An essential component of the pairing
process is for the child to recognize, before he or she is subjected to any demands, that the therapist is a fun person to be with. As the relationship builds between the new therapist and child, the therapist slowly places demands. This creates a positive relationship and sets the child up for success. One of the most important skills the center teaches is how to “mand” items. The term “mand” is commonly used in autism therapy, and it simply means to request. Teaching an autistic child how to request helps develop language and communication skills. American Sign Language or pictures will often be used to ask for items such as a ball, swing, or water. As the student becomes familiar with requesting what he or she wants, the therapist begins to work on developing vocal skills. Many of the students, including one of my own, begin at the center with sign language and later develop vocal skills. Getting a child to mand is not difficult. Before giving a child what he or she wants, the therapist has Human Interest ■ Volume 4 ■ Fall 2014 ■ 11
him or her request it. An example of this is stopping a swing and having the child request “swing” before giving him or her another push. Most of the students at the center require a daily mand track, where therapists write down their mands and prompt levels. Prompt levels vary for the types of manding - vocal, sign language, and pictures. Here are a few types prompt levels: Independent: When the child requests the item all on their own; this can be with pictures, vocalizations, and sign language. Vocal prompt: When a child requires the therapist to tell them vocally to request the item; this can be with pictures, vocalizations, and sign language. Partial physical prompt: Having to assist the child in a sign placement or slightly moving their hand to the desired picture; this can be with sign language and pictures. Full physical prompt: This requires full help from the therapist to select the picture of the item or create the desired sign; this can be with sign language and pictures.
By tracking mands and prompt levels daily, it is easy to see the child’s progress. The therapist records the student’s speech so he or she can monitor the child’s improvement in word clarity. An example would be saying the word “computer” to have the therapist turn it on or play a game. A child might start out saying “puter” and then as time progresses, will begin saying “caputer” and eventually “computer.” There are many different programs at the center, ranging from social to academic. The style of teaching utilized is unique in that it is built into 15 minutes intervals. Programs are designed to be completed in 15 minutes, so that the programming can be broken up into smaller time chunks with breaks in between. In order to monitor the progress of a child, a baseline is established by collecting data on how the child per-

A Typical Schedule at the
n order to portray an average morning for a student at the center, I followed around one of my students, Cheyenne, from 9:00am-noon. Cheyenne is 6 years-old and has been at the center for a couple of years. I was put on her team this summer, and it has been a joy to watch her develop! 9:00-9:05am: Cheyenne checks into the center, just like one would at school. Cheyenne takes her lunch box to the kitchen and puts it in the fridge. 9:05-9:20am: After a morning bathroom break, the therapist begins playing with Cheyenne before running morning programs. These games are fun for Cheyenne! 9:20-9:35am: The cold probe is run and Cheyenne takes part in her first program of the day. 9:40am: Cheyenne requested to use the bathroom and because she asked, she gets her highest reinforcement: the swing! 9:55 am: The therapist runs a morning mand track for Cheyenne, and Cheyenne requests the computer. Cheyenne waits in line. She later requests “Care Bears” and watches a video on YouTube. The therapist pauses the video every 20 seconds or so for Cheyenne to mand for “play” or “computer.” 10:15 am: Cheyenne requests to play in the toy room. 14 ■ The Medical Decoder ■ Phi Delta Epsilon IL Gamma
Rochester Center for Autism 10:30am: After the mand track is over, Cheyenne’s therapist runs a NET program where Cheyenne must follow instructions. This specific program requests that Cheyenne go to two different therapists on her team and complete two actions. Today, the request was to “give Ashley a hug and Sarah a high five.”
10:45am: A table session is run. Because the cold probe is finished, the therapist runs an errorless session. An errorless session consists of the same program as the cold probe, but if the student is about to make an error, the therapist will interject and prompt the correct answer. 11:00am: The therapist gives Cheyenne an option of trampoline or books. Cheyenne chooses books. The therapist waits before turning each page for Cheyenne to mand “turn the page.” 11:20am: Cheyenne requests to go to the ball pit, and then changes her mind to go to the indoor swing instead. When choosing activities, it is important to keep the 80-20 rule in mind- 80% of the activities are the student’s choice, 20% are the therapist’s choice. This is to make sure the student is learning to transition and engage in activities that are not always his or her immediate preference. Again, the therapist at the swing waits to push until Cheyenne mands “swing.” 11:40am: Cheyenne and the therapist return back to the table for another round of errorless. While the therapist is marking down a round of errorless and preparing for the program, Cheyenne reads a story. Noon: Cheyenne heads off to lunch! ÌMD For references, see page 52.

Establishing a Nexus Between Public Health and Clinical Practice By Jane Wang
T
he relationship between public health and clinical practice is easy to overlook. The former is often associated with an overarching, big-picture approach that addresses issues plaguing populations, while the latter is seen as more individualized and personal. However, despite such distinctions, the two are inextricably linked. This link is often apparent in the treatment of diseases, a primary duty of physicians. While treating illnesses is an important part of maintaining health, well-being stems from a complex web of factors that relate to public health issues, such as access to healthy food, neighborhood safety, exercise, stress, and education.
The mutually dependent nature of the two fields is especially apparent in underserved neighborhoods. For example, neighborhoods of lower socioeconomic status are more likely to be food deserts, areas where it is difficult to purchase nutritious, healthy produce. According to the United States Department of Agriculture (USDA), a neighborhood is officially deemed a food desert if “at least 500 people and/or at least 33% of the census [region’s] population resides more than one mile from a supermarket or large grocery store.”1 Low access to healthy food means that residents of these neighborhoods are more likely to resort to fast food for sustenance, a habit that has adHealth Care & Policy ■ Volume 4 ■ Fall 2014 ■ 17

soup kitchens because they did not have sufficient food for themselves and their families on a day-to-day basis. Other patients could not afford transportation to and from doctor appointments; it was not uncommon to see people miss appointments for this reason. To address these issues, the nonprofit organization (NPO) that placed me at this clinic forged a partnership with the physicians there. After the doctors saw patients for their medical needs, volunteers from the NPO would speak to patients to address any non-medical resources they needed, including food and employment. In this way, fundamental necessities that impact health were addressed in addition to the actual illness. To see people from all areas of the health care sphere – physicians, MBA grad-
uates, college students, and social workers – work together to improve the health of patients was humbling. It made me realize that physicians, although immensely important for maintaining health, are ultimately part of a wider web of support for their patients. Health cannot be viewed through a narrow lens that only focuses on the immediate problems presented by a patient. Well-being is impacted by a myriad of factors and circumstances, all of which combine to weave a complete picture of patient health. Choosing to only treat immediate health concerns rather than to address overarching issues allows fundamental problems to go unnoticed. Thus, although the domains of public health and clinical practice are often viewed as separate spheres, it is imperative that a nexus between the two be established in order to address issues that impact both individuals and populations.

The Effects of the Anti-Vaccination Campaign:
A Retrospective Look By Danielle Yin

never enjoyed receiving shots at the doctor’s office. Although I can handle that painful prick of the needle without causing a scene, I cannot help but feel a momentary spark of anger at my parents and my doctors whenever I have to endure that uncomfortable experience. Still, my dislike for receiving vaccinations is outweighed by my appreciation for what they have done for society, as they have virtually eliminated many preventable diseases. However, not everyone shares my appreciative sentiment. The recent uprising of anti-vaccination campaigns has alarmed physicians across the United States and the United Kingdom. As the facts regarding the harmful effects of these campaigns emerge, it is essential to educate ourselves on the origins of these movements and on the importance of public vaccination.

to evade the vaccination requirements set by many schools, citing personal or religious reasons. Despite evidence supporting the effectiveness of vaccines, many parents also doubt the effectiveness of vaccines, calling into question whether or not these immunizations actually prevent the diseases they claim to. Studies have found that the chance of outbreaks of diseases such as pertussis, commonly known as whooping cough, is 2.5 times greater in areas that permit personal-belief exemptions.3 The decline in vaccination rates has also caused an increase in mumps cases. In early 2005, almost 5,000 cases of mumps were reported, a dramatic increase compared to the few cases that were present in the late 1990s.4 While some parents claim that it is their right to choose whether or not their children get vaccinated, they fail to comprehend the nature of how infectious diseases are spread. By sending their unvaccinated children into the general population, parents damage the concept of herd immunity. In order to protect those who cannot be vaccinated for reasons such as pregnancy, age, or health, 95% of the population must be immunized.5 When this percentage falls, previously avoidable diseases like polio or measles can re-emerge. This has already been seen in California, where only 91% of kindergarteners were vaccinated in 2010. These lower vaccination rates played a major role in a massive pertussis outbreak.5 The harmful effects of anti-vacci-
nation campaigns have manifested in the rising rates of preventable illness. From 2011 to 2012 in the US, whooping cough cases increased more than threefold in 21 states.6 Looking forward, easily preventable diseases may re-emerge, causing unnecessary danger to both patients and the health care system. It may be time to make changes to the way doctors approach the topic of vaccines with their patients. Instead of waiting until the typical two-month checkup, a pediatrician can address the subject during pregnancy so expecting parents can have time to do research and make an informed decision regarding vaccinations. To emphasize the necessity of vaccination, doctors should share facts as well. For example, recent studies involving children in Colorado showed that unvaccinated children were nine times more likely to contract chicken pox and six times more likely to end up hospitalized with pneumonia.7 Parents need to be reassured of the quality of testing utilized in vaccine safety studies, a system that operates independently from the pharmaceutical companies that manufacture them.7 As the next leaders in health care, it is our responsibility to educate future parents in order to prevent the anti-vaccination trend from causing lasting harm.

enicillin. Ibuprofen. Aspirin. These are just a few examples of drugs that have benefited our society. It is incredible how far drug discovery has come; we can manipulate biology and use organic molecules as vehicles to treat and cure various diseases. With these advancements, we can selectively target various symptoms and extend the average lifespan. While these treatments have greatly contributed to society, they also are tremendously costly to develop and produce. This applies not only to consumers who purchase these drugs,
but also to the researchers and pharmaceutical companies that spend years trying to develop effective medications. The process of discovering and developing pharmaceuticals is extremely complex.

still developing. Sometimes, the program may predict activity, while in reality the chemical is inactive. The program might also fail to predict certain chemicals that could effectively treat a disease. Even with this technology, hundreds of chemicals still need to be synthesized before finding the one that has the desired activity in a biological model. When a drug has shown promise, it is tested in animal studies to further examine the properties of the compound. One important step towards achieving a better understanding of the compound’s characteristics is determining the pharmacokinetics of the drug, which means determining what happens to the drug once it enters an animal’s body. To comprehend the pathways a drug follows, researchers must investigate its absorption rate into the bloodstream, distribution to the various tissues, degradation, and elimination from the body. It is also important to note that even if the drug shows activity in the initial biological model, this does not guarantee that the compound will show activity in the animal model.
Each stage brings a new layer of complexity, progressing from a single cell model, to an animal, and eventually to a human being. If the drug is successful in the animal models and is shown to be nontoxic, it is then moved on to clinical trials. From the hundreds of thousands of chemicals in the initial chemical library, only a handful of compounds actually enter this stage. However, many do not make it through the clinical trial. With each phase, the number of patients tested increases, and the drug has to pass more rigorous tests. While drugs may have shown promising results in the animal studies, they may fail to produce similar results in human trials. For example, some drugs have ap-

peared to “cure” diseases such as ALS in animals, but fail to have the same effect in clinical trials. The process of drug discovery can be long and tedious, with countless obstacles prior to introduction into the market. Unsurprisingly, such a process requires a great deal of money to fund the work and time it entails. A recent Forbes study has shown that larger pharmaceutical companies spend up to $6.3 billion
per drug, while smaller companies spend up to $2.8 billion.2 Due to the extremely high cost in researching and developing medicine, most of the research is performed industrially, as opposed to in an academic environment. Large pharmaceutical companies such as Johnson & Johnson and Pfizer, Inc. dominate this industry, as they possess the money to fund this type of research.
Developing LyricaTM: Silverman Strikes Gold Success stories in the realm of academic drug development do exist. Dr. Richard B. Silverman’s discovery of LyricaTM, also known as pregabalin, serves as an example of academic drug research that made the leap into industry. Silverman’s path to successful drug discovery highlights the time, effort, and potential payoff of academic drug research. Silverman joined the chemistry department at Northwestern University in 1976 and began researching various small molecules that affect the level of gamma-aminobutyric acid (GABA) in the body. It has been shown that “when GABA levels fall too low in some people, it can trigger epileptic seizures.”3 Therefore, Silverman’s lab developed various compounds to increase GABA production in the body. However, the drug that brought acclaim to Silverman and his research did not actually alter GABA levels. In fact, the discovery of LyricaTM was a surprising one. According to The Chicago Tribune, “Silverman’s experience suggests finding a chemical that turns into a billion-dollar drug takes as much luck as winning the lottery.”4 While it did not affect
28 ■ The Medical Decoder ■ Phi Delta Epsilon IL Gamma
GABA levels as was initially hypothesized, LyricaTM still showed incredible efficacy in the treatment of epileptic seizures as well as other illnesses, such as neuropathic pain and fibromyalgia. In November 1990, Silverman applied for a patent, which was not approved until March 2001. When Silverman first noticed a few compounds that showed great results in affecting GABA levels, he began to look for companies that would be interested in partnering with him to continue the study of these chemicals. Two companies demonstrated interest in this study: Upjohn Pharmaceuticals and Parke-Davis Pharmaceuticals.6 Upjohn only asked Silverman for the compound with best activity, whereas Parke-Davis asked for all of the compounds. The drug initially thought to be the best candidate was not effective when studied further. However, one of the compounds in the library of chemicals sent to Parke-Davis showed high potential. Though Dr. Richard Silverman of Northwestern University its official mechanism of action was not yet fully understood, the performance of the compound proved to be so convincing that Parke-Davis and Northwestern proceeded to sign a patent option agreement in December 1991. Over the next six months, Parke-Davis used the compound to perform many animal studies such as pharmacokinetics and metabolism experiments. Afterwards, another two years were spent on studying an-
Science & Technology ■ Volume 4 ■ Fall 2014 ■ 29
imal toxicology and on synthesizing a specific enantiomer. In December 1995, Parke-Davis filed an investigational new drug application, which allows for clinical studies on a compound before approval by the US Food and Drug Administration (FDA). Phase I of clinical trials started in late 1995 and lasted for two and a half years. A combined Phase II/III trial was then performed from 1999-2003, which involved 100 different clinical trials and tested over 10,000 patients. In 2000, Pfizer bought Warner-Lambert, which had acquired Parke-Davis in 1970, so Pfizer continued studies on the compound. It was also around this time that the compound started being referred to as “LyricaTM”. When PfizThe Richard and Barbara Silverman Hall for Molecular er took control of Therapeutics and Diagnostics at Northwestern University. the research, they pushed aside Silverman, the initial inventor. As Silverman said, “I became an outsider... There was no longer the possibility to talk with their scientists. No comments. They had a launch party for the drug, and I asked to come. Nope. No party for me. They take your stuff and tell you to go away.”4 This is where academic and industrial research part paths and utilize different ideologies. Large pharmaceutical industries are able to research new
30 ■ The Medical Decoder ■ Phi Delta Epsilon IL Gamma
medications as long as they have exclusive profit rights, which requires secrecy about what they are doing. In academia, innovative science, which includes collaboration and publication, is the principal driving force. After continuous success, Pfizer filed a New Drug Application in October 2003 to request approval for LyricaTM to become a commercial product. This was approved by the FDA in 2004. In 2006, during the drug’s first full year on the market, LyricaTM had $1.2 billion in global sales. The next year, Northwestern sold a sizable amount of the royalty interest of LyricaTM to Royalty Pharma for $700 million. With this, Silverman donated part of his royalties to Northwestern to help build a new building for molecular therapeutics and diagnostics. His goals were to broaden the research environment and continue to bring great professors from around the world to the university. Although Silverman hit a scientific jackpot, he continues to perform outstanding research on drug development and hopes to help find treatments for various neurodegenerative diseases such as Parkinson’s, ALS, and Huntington’s. In a competitive research environment dominated by major pharmaceutical companies, Silverman’s development of LyricaTM serves as a source of inspiration to other academic drug researchers. While few drugs go on to become blockbuster drugs like LyricaTM, advancements in technology and a greater understanding of the human body offer promising developments. Drug development, whether academic or industrial, offers hope for the future of medicine to cure disease and even extend longevity. With creativity, imagination, hard work, diligence, and perhaps a little luck, major drug discoveries can be made in an academic setting. ÌMD For references, see page 53.

mine, a neurotransmitter important in the nervous system’s pathways responsible for producing feelings of satisfaction and fulfillment.4,9 This shortage in ADHD patients is caused by a high density of active transporters that remove dopamine from the brain. Prescription stimulants raise dopamine levels in the brain by in-
hibiting the ability of the transporter to remove the dopamine, thus improving focus in ADHD patients.4,10 Unfortunately, these medications, touted to bolster concentration, are frequently abused by nonprescription users. Improper use of ADHD medications, like Adderall, is especially observed among college students. Misuse of prescription stimulants on college campuses is a major concern.4 Abuse rates range across colleges; 6.9 to 34% of undergraduate students report illicit use of prescription stimulants during their lifetimes.5,12,13 Frequently cited reasons for stimulant misuse include improving concentration and alertness when studying and attaining a “high” akin to that of cocaine.4,13 Despite widespread use in universities, many illicit users of prescription stimulants are unaware of the effects of these drugs.11 Students who use stimulants often rely on friends’ testimonials rather than medical literature in their assessments of the drug’s risks.11 Furthermore, the prescription of these medications for ADHD patients by doctors can lead people to falsely believe these drugs are safe for anyone to consume.11 The United States Drug Enforcement Agency rates medications and recreational drugs on a scale of Schedules Science & Technology ■ Volume 4 ■ Fall 2014 ■ 35

Brigham Young University study also found that the most frequently reported adverse effects of Adderall use on students were sleep deprivation and loss of appetite.16 Nonprescription consumption of stimulants for academic advancement is also of questionable integrity. For this reason, the use of stimulants to heighten performance in academic settings is now seen as being comparable to the use of anabolic steroids in professional sports.11 In line with this thinking, Duke University recently listed “the unauthorized use of prescription medication to enhance academic performance” under “cheating” in its classification of academic dishonesty.4,18,19 This ban could reduce the incidence of these medications’ misuse and in turn limit the frequency of negative side effects. So, does using stimulant medication without an ADHD diagnosis really improve academic performance? The short answer is no. The majority of studies exploring stimulant use by nonADHD patients have shown little to no performance gains. Recently published research has demonstrated that stimulants are effective primarily in patients with ADHD and serve to bring patients back to “baseline” rather than bolster already normal performance.4 Additionally, studies have shown that there is a placebo effect among nonprescription users of Adderall. According to a 2011 study published in Experimental & Clin-
ical Pharmacology, certain students became more attentive after receiving a placebo, because they believed they were being given stimulants.4 However, a lot remains unknown about the effects of stimulants in nonADHD patients, largely due to the fact that stimulant abuse for the sake of enhancement has been stigmatized in medical circles.20 There seems to be a common misconception between concentration and performance; while stimulants may increase alertness or concentration, experiments have failed to show a clear correlation to increased performance. Furthermore, the dangers incurred by stimulant abuse seem to far outweigh possible benefits. While possible gains from drug abuse remain hazy, the risks, both medical and legal, are real. Ultimately, the nonprescription use of ADHD stimulants such as Adderall is not effective in improving academic performance in individuals without the disorder. Misusing these medications exposes students to medical and legal risks with minimal benefit. It is important that students gain insight into the misinformation that circulate on college campuses regarding the use of ADHD stimulants in order to protect their health, avoid potential legal problems, and maintain academic integrity.

The Fusion of Medicine and Technology What can we envision for the Future of Health Care? By Elizabeth Zborek
T
he past decade has seen a rise in the use of electronic health records (EHR), electronic referrals to specialists, and e-prescriptions to pharmacies. This transition towards a more electronically-focused approach to health care demonstrates the growing influence of health information technology (HIT). HIT encompasses any technological advancement that is employed to collect, store, analyze, and share health information.1 HIT has manifested through many technological innovations, such as the digitalization of medical diagnostics and the advent of mobile health applications. The HIT era emerged as a means to address the issues of health care costs, medical errors, and the disconnect between health care providers.2 Its growth can be traced to the 1960s when the Medicaid and Medicare programs were enacted, and the need for an organized
billing process was met with mainframe computers and centralized processing.3 Smaller and more affordable microcomputers (PCs) emerged in the 1980s, and became increasingly used for clinical information systems and for maintaining billing information.3 The 1990s saw the dawn of the Internet, and health care workers took advantage of it as a potential form of communication between providers.3 More recently, The American Recovery and Reinvestment Act and The Health Information Technology for Economic and Clinical Health Act (HITECH) of 2009 introduced financial incentives for professionals who demonstrated proficiency in a certified EHR program.5 These incentives were offered in hopes of achieving improvements in care delivery, enabling patients to be engaged in the health care process, and helping providers avoid preventable medical er-

iTriage helps patients narrow down the cause of their symptoms, identify local providers, clinics, and hospitals, and stay up to-date-with latest health news.
HealthTap
This app helps doctors and clinics attract and educate new patients while improving the quality of health information online. Additionally, it connects patients with doctors to give them the best health information.
palmEM
palmEM covers hundreds of the most commonly encountered conditions in emergency medicine. The app contains quick medication references and helps doctors with clinical decision- making. Many similar apps have appeared on the market, in order to help physicians and residents quickly and efficiently give a patient a diagnosis.
InQuicker
Not exactly a typical mobile app, InQuicker is a site that can be used on all mobile devices, much like Patient Portal. It reduces the time that hospital personnel spend on data input by allowing patients with non-life threatening illnesses to check into the emergency room from home. Patients can wait at home instead of a crowded waiting room until they are called in to be seen by a health care provider.
Doctor on Demand
Patients utilize this app in order to get in contact with board-certified doctors for non-emergency medical purposes. They pay a $40 fee for each video visit, and doctors are able to diagnose patients and prescribe medications when clinically appropriate. ÌMD For references, see page 55.

research participant enters a room and takes a seat in a reclined chair. She gazes nervously at the computer screen in front of her. She is about to begin a standard, decades-old procedure for ameliorating fears associated with blood, injection, and injury, referred to as BII phobia. The researcher displays photos on the computer screen for the participant. These images begin with a photo of a syringe and progress towards more fear-inducing images, such as pictures of open wounds and surgical procedures. After viewing each photo, the research participant is asked to rate her level of distress and to describe her physiological symptoms. Her palms be-

This participant was part of a psychology research study conducted at Northwestern University by Ph.D. candidate Nehjla Mashal in order to observe the effects of BII phobia.1 According to the DSM-IV-TR, a manual that health professionals use to classify mental diseases, BII phobia is an anxiety disorder characterized by a marked and persistent fear induced by the presence or anticipation of blood, injuries, wounds,

or receiving an injection.2 Although the person recognizes that the fear is excessive or unreasonable, the individual attempts to avoid situations that will instigate this phobia. If unavoidable, he or she endures the phobic stimulus with intense anxiety or distress.2 About 4% of the population in the US has the BII phobia.3 Unlike other disorders and phobias, which simply result in high levels of anxiety, the BII phobia can actually induce fainting. When confronted with the feared stimuli, a person with this condition usually undergoes a two-phase reaction. In the first phase, the person experiences the sympathetic fight-or-flight response, which is typical in most anxiety disorders and phobias. This response is accompanied by an increase in blood pressure and heart rate. The second phase is unique to BII phobia and consists of a rapid fall in heart rate and a rapid decrease in blood pressure that causes a reduction in blood flow to
the brain.3 This second phase produces the symptoms that can lead to fainting. Slightly more than 50% of people with needle phobias and 70% of people with blood phobias have a history of fainting during an injection or during exposure to blood, respectively.4 Although the BII phobia includes fear of blood, injury, and receiving an injection, the specific triggers depend on the person. Additionally, studies have shown that not all patients with BII phobia have identical physiological responses.3 According to Mashal, those with BII phobia “come to associate stimuli, like needles and blood, with that unpleasant physiological response, which potentiates the phobia.”1 Although the phobia may not immediately interfere with one’s life, suffering from BII can create substantial problems for individuals as they get older. “One of the motivations for people to get help is that it’s getting in the way of getting medical care. It may not be a big deal in your twenties, but it’s a big deal when you get older and need more regular tests,” Mashal explained.1 In addi-

Treat Patients, Not Diseases By Paulo Tabera-Tarello
A
s medical students, it is easy to believe that after years of undergraduate study and hard work, we are ready to be great physicians. However, becoming a successful doctor is not something that can be achieved solely through studying textbooks or scoring well on exams. While these are certainly important components, some of the qualities that make physicians great are acquired through observations and experiences in a hospital. I will recall my time in medical
school as an anthology of experiences and clinical tales that will allow me to shape my judgment as a physician. Thus far, I have learned that failure can instruct better than success, and a single bad decision can shape you in a way that fifty good decisions never could. I will look back on these memories, both the good and the bad, when the time comes for me to treat patients on my own.

that by the end of our education, we are capable of caring for our patients while always trying to achieve the best outcome for their health. However, we learn to do all this from a perspective that can fail to accurately depict the effects that diagnoses have on patients and their families. To a busy doctor, the pain that a difficult diagnosis brings upon a patient and his or her family can all too often become abstract and distant. Physicians must realize that when they take the time to truly empathize and identify with their patients’ situations, they can provide more holistic care.
The medical profession is not just a typical nine-to-five job; this profession is about understanding the complex systems of the human body in order to ultimately come to the aid of the patient and ease his or her pain. However, throughout all the years of medical school training in Mexico, we still do not have a class where we learn how patients cope with these unfortunate circumstances. We start learning how to be doctors without understanding the patient perspective. Though my experiences as a student in Mexico may be unique, medical students and doctors universally may not fully comprehend the scope of a patient’s experience with illness. When we choose to realize the crucial role that empathy for the patient has in health care, we can start changing the paradigms of the health profession. These changes to the overall mindset of doctors will be essential because, after all, we treat patients, not diseases. ÌMD
