Non-organic Vision Loss in the Afghanistan and Iraq Conflicts.

Non-organic visual loss (NOVL), defined as a decrease in visual acuity or field without an identifiable organic cause, can be challenging to diagnose, especially in patients whose NOVL is superimposed on some component of true organic pathology. Exposure to combat puts soldiers at risk of emotional distress and physical trauma, which can contribute to the development of NOVL with conversion disorder or malingering. This case series describes six patients with NOVL who sustained ocular or non-ocular injuries while serving in combat operations in Iraq and Afghanistan, and highlights diagnostic pearls and components of inter-disciplinary management in the unique military context.

Hemorrhagic Stroke in a Young Healthy Male Following Use of Pre-Workout Supplement Animal Rage XL.

So-called "pre-workout" supplements are substances marketed as natural dietary supplements with claims of helping athletes achieve more focused and intense workouts. The use of such products remains popular among American youth as a whole, but is especially high among active duty service members. Supplements are minimally regulated by the Food and Drug Administration (FDA), and unlike pharmaceuticals, supplements are often brought to market without any testing to show neither efficacy nor safety. Several case reports have documented serious adverse events and raise the question of whether supplement use was a causative factor. Reported events occurring after use of pre-workout supplements include, among others, ischemic stroke, hemorrhagic stroke, myocardial infarction, hepatitis, and death. Here, we present the case of a healthy 25-year-old active duty male who experienced a bilateral cerebellar hemorrhagic stroke occurring shortly after taking a supplement named Animal Rage XL. Hemorrhagic stroke occurring in a healthy 25-year-old male with no risk factors is exceedingly rare. This is the first known case of stroke temporally associated with this particular supplement, which is currently available for purchase at military exchanges. Additionally, several of the active ingredients in this supplement have been shown to cause hypertension, tachycardia, and vasospasm. All of these effects could increase the likelihood and severity of a hemorrhagic stroke. The investigated ingredients in this abstract include ß-phenethylamine, creatine-monophosphate, and caffeine.
