When Clopidogrel Fails…

Marisa Mizus

Faculty peer reviewed

Clopidogrel (Plavix) has been the standard of care for patients with coronary artery disease following percutaneous coronary intervention (PCI) for the past decade.  Although it is a successful antiplatelet treatment in many patients, like any hero, it has a weakness: formation of its active metabolite depends on two hepatic cytochrome P450 (CYP450)-dependent steps.  Clopidogrel resistance, or non-response, is correlated with an increased risk of major adverse cardiovascular events, including reinfarction and stent thrombosis.(1)  It is often unclear why a patient …

When Minutes Matter: Why Do Patients Wait to Seek Treatment Following a Stroke or Heart Attack?

Laurel Geraghty

Faculty peer reviewed

Both stroke and heart attack require rapid treatment following the onset of symptoms to minimize morbidity and mortality, but few patients seek help in a timely manner. Only about half of patients with acute myocardial infarction (AMI) or stroke arrive to the emergency department within four hours of the onset of symptoms.,,, Every 30-minute delay in treatment following AMI increases one-year mortality by 7.5%, and almost half of the 167,000 annual stroke deaths in this country occur before the patient …

Zinc Cold Remedies: Are They Safe and Effective–Who Nose?

Amanda Benkoff

Faculty peer reviewed

Each year doctors are presented with the dilemma of the common cold. Adults in the U.S. experience an average of 3 colds per year, and children up to 8-10, resulting in over 500 million colds annually.(1) Patients often visit the doctor with cold symptoms requesting antibiotics. Since the etiology of the common cold is viral, antibiotic therapy is ineffective and inappropriate, and only contributes to bacterial antibiotic resistance. More than 200 viruses can cause the common cold, including rhinoviruses, coronaviruses, …

Carly Oboudiyat

Faculty peer reviewed

You finally have the “dizzy” patient whose eyes actually beat torsionally upwards when you do that silly maneuver you have done countless times to no avail. Hallelujah, you think, a positive Dix-Hallpike sign, reassuring you that you have a case of benign paroxysmal positional vertigo (BPPV). But now what? Do you try that other acrobatic maneuver to reposition the canaliths in the posterior canal, or should you give meclizine?

Faculty Peer Reviewed

The incidence of male pattern hair loss can reach almost 100% in some ethnic groups.1, 2 While treatment of the condition is usually deferred to dermatologists, it is often the primary care physician (PCP) who is first approached for advice. Several medical and surgical treatments exist for male pattern hair loss. Herbal supplements and products on infomercials make cursory non-FDA-approved claims of hair growth. Minoxidil, once developed for hypertension, is available over the counter as a scalp treatment. Finasteride and …

Guidelines for Colorectal Cancer Screening and the Recent Evidence Behind Them

 Nazia Hasan, MD MPH

Faculty peer reviewed

For most residents, screening for colorectal cancer (CRC) may seem as established as that for breast and cervical cancer. In reality, the use of CRC screening has only recently approached that of screening for those other malignancies. We have seen recently changes to the CRC screening guidelines last published by The American College of Gastroenterology in 2000. The updated screening guidelines for colorectal cancer became available in …

Meeting Perspectives: American Heart Association Scientific Sessions 2009

Steven Sedlis, MD

 

The annual scientific session of the American Heart Association (AHA) was held in Orlando on November 14-18 2009. It felt like a ghost town. I ran into Ira Schulman, my medicine resident at Bellevue when I was a third year medical student; we looked at one another and simultaneously blurted out “where is everybody?” Well Ira remains my role model and hero and it goes to show that although attendance at major medical meetings may wax and wane, the impact of a …
