Beta-blockers in Uncomplicated Hypertension: Is it Time for Retirement?

By Robin Guo, MD

Peer Reviewed 

Beta-blockers were one of the first modern medications used for the treatment of blood pressure. Before 1950, treatment options for hypertension were limited. The alphabet soup of medications—reserpine, pentaquine, hydralazine, and guanethidine—were notorious for inducing orthostasis, sedation, constipation, impotence, or blurry vision . Then in the 1960s, propranolol and chlorothiazide were developed. Initially designed to treat angina pectoris, propranolol was serendipitously discovered to also lower blood pressure. Oddly, propranolol, like the other beta-blockers in its generation and thereafter, did …

Obesity-related health conditions, including diabetes, heart disease, certain types of cancer, and stroke are among the leading causes of preventable death. Yet, obesity is not the sole contributor to these diseases. Other health risk behaviors, including smoking, alcohol abuse, and lack of physical activity all interact to …

Chronicles of a Second Year Medical Student

Day 1 of the medicine rotation: complete. I was on long call today, which meant three things. One, the hours during which I had to pretend I knew something were longer. Two, I saw a lot of things I had never seen before, from more common things like COPD exacerbations and acute pancreatitis to more obscure things like erythrodermic psoriasis and multiple brain abscesses. And third, it’s 8 PM and I am absolutely exhausted.

As I lie down and start …

By: Miguel A. Saldivar, MD

“Indeterminate.” Many clinicians have expressed frustration when reading this word on a Quantiferon-TB Gold test result. The obligate follow-up question is: what is the next best step? Repeat the Quantiferon? Ignore it altogether and perform a Tuberculin Skin Test (TST) instead? Even worse, what happens when both tests are performed with discordant results? In order to answer some of these questions, this article begins with a very brief overview of Mycobacterium tuberculosis (TB) infection epidemiology. This is followed …

Yet recently, writer Markham Heid informed coffee addicts all over the world, “Drink Coffee, Lower Your Diabetes Risk” . To add to that, it’s not just coffee; tea and decaf can do it too, or so his article proclaims. Skeptical? Let’s review the evidence and judge for ourselves.

The Rise in Tick-Borne Diseases: Is Climate Change Responsible?

By Nadia Jafar

As a resident of Connecticut, I grew up acutely aware of tick-borne diseases. Nonetheless, I was surprised to see at least 3 cases of tick-borne infections during the month of my Medicine clerkship. This drove me to research the incidence of tick-borne diseases, specifically in the US, and the possible factors contributing to their increased prevalence.

In 1998, the list of reportable tick-borne pathogens in the US included Rocky Mountain spotted fever, tularemia, Lyme disease, human granulocytic ehrlichiosis/anaplasmosis, and human …
