Did Abraham Lincoln Have Marfan Syndrome?

By Anna Krigel

Faculty Peer Reviewed

The iconic image of Abraham Lincoln is ubiquitous in our lives, from his small face on the penny to his large figure looming over the National Mall in Washington, D.C. Lincoln fascinates historians because of his significant role in American history when our nation was bitterly divided, but he intrigues physicians because of his remarkable stature. A reporter once described the 16th president as a “tall, lank, lean man considerably over six feet in height with stooping shoulders, long…

“Red Meat Kills.” “Red Meat a Ticket to Early Grave.” “A Hot Dog a Day Raises Risk of Dying.” Such were the headlines circulating in popular press last year when the Annals of Internal Medicine released details of an upcoming article out of Frank Hu’s research group at the Harvard School of Public Health . Analyzing long-term prospective data from two large cohort studies, researchers found that individuals who ate a serving of unprocessed red meat each day…

White Coat Hypertension: Are Doctors Bad for Your Blood Pressure?

By Lauren Foster

Faculty Peer Reviewed

Hypertension is a pervasive chronic disease affecting approximately 65 million adults in the United States, and a significant cause of morbidity and mortality . Antihypertensives are widely prescribed due to their effectiveness in lowering blood pressure, thereby reducing the risk of cardiovascular events. However, the phenomenon of the “white coat effect” may be a complicating factor in the diagnosis and management of hypertensive patients. It is well established that a considerable number of people experience an elevation of their…

Morgellons: Real Disease or Delusion Turned Internet Meme?

By Robert Mazgaj

Faculty Peer Reviewed

Morgellons disease is an “unexplained dermopathy” characterized by fibers emerging from skin lesions, and associated with various cutaneous sensations. Inspired by a curious medical condition reported by a 17th century English physician, Morgellons was actually named in 2002 by Mary Leitao, a layperson, to describe the mysterious set of symptoms reportedly suffered by her then 2-year-old son. Leitao then launched the not-for-profit Morgellons Research Foundation (MRF) along with a (no longer active) website, www.morgellons.org. MRF successfully petitioned members of…

Are Dentists Really Causing Infective Endocarditis?

By Jeffrey Krutoy, DDS

Faculty Peer Reviewed

Bacterial infective endocarditis is a potentially devastating disease, and while it may be an easy tradition to blame the dentist, recent research and new guidelines from the American Heart Association (AHA) indicate that it may not be so simple.

Infective endocarditis (IE), while relatively uncommon (with yearly incidence rates ranging from 2 to 6 cases per 100,000 people), results in high rates of morbidity and mortality even when treated. For this reason, physicians have emphasized the importance…

Should We Measure Apolipoproteins to Evaluate Coronary Heart Disease Risk?

By Navya Nair, MD

Faculty Peer Reviewed

Coronary heart disease (CHD) is the major cause of mortality worldwide. Lipoproteins play a major role in the development of this disease. Current guidelines advocate that low-density lipoprotein (LDL) cholesterol should be the primary target for lipid lowering therapy. However, there is a growing literature on the atherogenic potential of apolipoprotein B (apo B)-containing lipoproteins and the protective effect of apolipoprotein A-one (apo AI)-containing lipoproteins. Many studies suggest that these apolipoproteins be used as markers to evaluate risk…

Should I Consider Antibiotics in My Patient with Irritable Bowel Syndrome?

By Jason Chalifoux

Faculty Peer Review

The story of a patient with multiple office visits due to uncontrolled abdominal pain, bloating and diarrhea/constipation is common among primary care doctors and gastroenterologists. The workup is often extensive and rules out many etiologies. After discovering no metabolic, inflammatory, or anatomic pathology, physicians use the Rome III criteria to diagnose irritable bowel syndrome (IBS). IBS is a functional bowel disorder that is diagnosed by symptoms of recurrent abdominal pain or discomfort for at least 3 days per month…

Is a VBG just as good as an ABG?

By Sunnie Kim, MD

Faculty Peer Reviewed

A rapid response is called overhead. As white-coated residents rush to the patient’s bedside, the medical consult starts to shout out orders to organize the chaos. “What’s the one-liner?” “Whose patient is this?” And of course, “Who’s drawing the labs?” Usually, at this point, the intern proceeds to collect the butterfly needle, assorted colored tubes, and the arterial blood gas (ABG) syringe. If lucky, there’s a strong pulse. The intern pauses, directs the needle, and hopes for that…

Excessive consumption of ethanol (EtOH) has many deleterious effects on the human body. The heart is a target of damage from EtOH consumption, as chronic consumption of EtOH leads to decreased cardiac function and structural heart disease, including dilated cardiomyopathy.(1) The exact mechanism by which EtOH exerts its deleterious effects on the heart remains poorly understood and is an area of active…
