Sexually Transmitted Infections and Human Immunodeficiency Virus.

The human immunodeficiency virus (HIV) and sexually transmitted infections (STIs) are considered epidemics in the United States. Research on the association between STIs and HIV infectiousness and susceptibility has shown that STIs promote HIV acquisition and transmission via mucosal inflammation and ulceration caused by viral or bacterial pathogens. Some of the most common STIs associated with HIV are chlamydia, gonorrhea, syphilis, and herpes simplex virus type 2.

Management of Chronic Migraine and Occipital Neuralgia in Post 9/11 Combat Veterans.

Introduction: The rate of chronic migraine (CM) has been shown to be 20% or greater in the post 9/11 combat veteran population with a history of traumatic brain injury, while the rate is much lower at 3-5% in the general population. Studies have shown that medications such as oral topiramate or intramuscular injections of onabotulinum toxin A (Botox) have been used for CM prevention, and occipital blocks have been shown to be helpful in treating occipital neuralgia and short-term relief of CM. However, there are no known studies that have specifically evaluated the use of Botox and occipital blocks for reducing headache frequency in the US veteran population.

Mesenteric Ischemia.

Mesenteric ischemia is an uncommon disease most often seen in the elderly. This disease results from blood flow in the mesenteric circulation that inadequately meets metabolic needs of the visceral organs and, if untreated, eventually leads to necrosis of the bowel wall. Mesenteric ischemia is divided into 2 types: acute mesenteric ischemia (AMI) and chronic mesenteric ischemia (CMI).
