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…

Are continuous glucose monitors the answer for better glucose control in diabetes?

A poorly controlled type 2 diabetic who is non-compliant with his at-home glucose monitoring comes to Bellevue’s Adult Primary Care Clinic requesting a prescription for a needle-less glucose monitor…

Self-monitoring of glucose levels is a necessary evil of diabetes treatment. As the prospect of numerous needle-sticks each day in perpetuity is daunting to patients, researchers have been developing non- or minimally-invasive methods to measure blood sugar in hopes…

What is the Role of Drug Therapy in Treating Obesity?

Arlene Chung

Faculty Peer Reviewed

Despite the high prevalence of obesity1 and its associated morbidity2 and mortality 3,4, it represents one of the most difficult chronic conditions to treat. Barriers include a metabolically toxic environment, a history of ill-fated weight-loss regimens, and a general view of obesity as primarily a social, not a medical problem. 5 Deep down, the belief that obesity really is the result of gluttony and sloth probably persists. However, as we learn more about the…

Breaking News: FDA issues new warning for Exenatide (Byetta®)

Kanika Ballani, Pharm.D.
Diana Hubulasvili, Pharm.D.

 Developed by Amylin Pharmaceuticals, Exenatide (Byetta®) is an incretin mimetic that is used as an adjunctive therapy with metformin, a sulfonylurea or a thiazolidinedione to improve glycemic control in type 2 diabetic patients. Mechanistically, Exenatide mimics the actions of endogenous incretin hormone, glucagon-like peptide (GLP-1), causing an increase in insulin secretion which slows gastric emptying and leads to a decrease in food intake. On November 3rd 2009, the FDA issued a safety warning on Exenatide associating…

The Utility of GlycoMark ™: 1,5 Anhydroglucitol as a Marker for Glycemic Control

David R. Friedmann MD

Faculty Peer Reviewed

Hemoglobin A1 (Hb A1c) is the standard method for monitoring diabetic patients’ long-term glycemic control by indicating average blood glucose levels over a period of two months, or half of the average life span of red blood cells. A new biochemical marker GlycoMarkTM is a test that measures serum levels of 1,5-anhydroglucitol (1,5-AG), a monosaccharide derived from ingestion of food, slightly different in structure from glucose. The test has been available in…

A 42 year-old male phlebotomist with a history of anxiety presented to the emergency room complaining of four hours of dizziness and diaphoresis. He denied taking any medications.

His chest X-ray, EKG, and laboratory results, with the exception of plasma glucose, were within normal limits.

Class Act: Soy and Breast Cancer – What’s the Connection?

Commentary by Alexis Melnick, NYU School of Medcine Class of 2009

Faculty peer reviewed

With the increasing popularity of soy foods in the American diet, there has been considerable debate over the link between soy and the risk of cancer, particularly cancer of the breast. The interest in this association stems from soy-containing isoflavones, soybean-derived compounds with chemical structures similar to estrogens that act as weak partial agonists at estrogen receptors. Initial data supported the chemopreventive potential of soy and were based on several findings: the…
