By Tyler Litton, MD

Oropharyngeal squamous cell carcinoma (OPSCC) is relatively rare but incidence has increased in the US over the past 40 years.

Stroke 2.0: Novel methods of Detection, Selection and Intervention in Acute Cerebral Ischemia

By David Valentine, MD

Stroke is among the costliest disorders in the world for both individuals and society. Every hour of an evolving stroke kills 120 million neurons, destroys 830 billion synapses and degrades 714 kilometers of myelinated fibers, aging the brain by 3.6 years in those 60 minutes1. It is the leading cause of adult disability in the USA, currently costing $70 billion a year2 with $2.2 trillion more projected over the next forty years3. The global burden is even higher.

The Brain’s Effect on the Heart After a Stroke

By Rory Abrams, MD

Peer Reviewed 

The heart and brain are hopelessly intertwined. Their connection is greater than the tissues and sinews that physically tether them to the human body, and can be understood in three ways: 1) how the heart affects the brain, 2) how the brain affects the heart, and 3) how the heart and brain are both affected by various neuro-cardiac syndromes.  The heart’s effects on the brain are illustrated when there is hypoperfusion of the brain resulting in syncope, or when …

Outpatient Rhythm Monitoring: Available Options and Diagnostic Yield

By Iulia Giuroiu, MD

Peer Reviewed

A 70-year-old woman with hypertension, early dementia, and non-specific chest pain of unclear etiology presents with recurrent left-sided chest pain. Unfortunately, she is a poor historian; it appears that her chest pain is similar to past episodes. Prior workups, which included an echocardiogram, had been unremarkable. To confound matters further, the patient’s current pain appears to be reproducible when pressure is applied to her chest. She is admitted overnight for close observation. No electrocardiogram (ECG) changes are found and …

PTH versus PTHrP — Small Differences, Big Implications

Samantha Kass Newman, MD

Peer Reviewed 

A 48-year-old depressed male smoker with a bit of an alcohol problem presents to the emergency department with worsening fatigue, severe lower back pain, constipation, abdominal pain, and 4 days of coffee ground emesis.

This could be anything. Viral gastroenteritis? Perhaps. Food poisoning? Probably not. Upper GI bleed? Likely, given his alcohol use. You send off routine labs, and then are called for a critical value: his calcium is 13.8 mg/dL. The albumin is normal. Next, you check the …

In July 2010, the much-anticipated “National HIV/AIDS Strategy for the United States” was released to the public. In its introduction, the president declared, “Our Nation is at a crossroads…unless we take bold actions, we face a new era of rising infections, greater challenges in serving people living with HIV, and higher health care costs” . Indeed, the incidence of HIV infection in the U.S. has fallen dramatically over the last few decades, from initially 130,000 new infections annually in …

Is It Time to Reconsider Who Should Get Metformin?

By Lauren Strazzulla

Current FDA guidelines for the use of metformin stipulate that it not be prescribed to those with an elevated creatinine (at or above 1.5 mg/dL for men and 1.4 mg/dL for women). It is also contraindicated in patients with heart failure requiring pharmacologic treatment, and people over age 80, unless their creatinine demonstrates that renal function is not reduced. These guidelines are in place to prevent lactic acidosis, an understandably feared complication of metformin. However, metformin is, by consensus, the initial drug …
