As early as 1826, divers diving to great depths noted that descent often resulted in a phenomenon of intoxication and euphoria. In 1935, Albert Behnke discovered nitrogen as the cause of this clinical syndrome, a condition now known as nitrogen narcosis. ⋯ The syndrome remains relatively unchanged in modern diving when compressed air is used. Behnke's use of non-nitrogen-containing gas mixtures subsequent to his discovery during the 1939 rescue of the wrecked submarine USS Squalus pioneered the use of non-nitrogen-containing gas mixtures, which are used by modern divers when working at great depth to avoid the effects of nitrogen narcosis.

Occasionally, difficulty with standard urethral catheterization is encountered. ⋯ In some male patients in whom performing standard urethral catheterization is difficult, TAUS reveals the tip of the catheter and TAUS-guided catheterization with transrectal pressure can be safe and useful.

Diarrhea and chest pain are common symptoms in patients presenting to the emergency department (ED). However, rarely is a relationship between these two symptoms established in a single patient. ⋯ Campylobacter-associated myocarditis is rare, but performing the appropriate initial diagnostic testing, including stool cultures, is critical to making the diagnosis. Identifying the etiology of myocarditis as bacterial will ensure that appropriate treatment with antibiotics occurs in addition to any cardiology medications needed for supportive care.

Case Reports
Recurrent Posterior Reversible Encephalopathy Syndrome in a Pediatric Patient With End-stage Renal Disease.
Posterior reversible encephalopathy syndrome (PRES) is a condition manifested by altered mental status, seizures, headaches, and visual loss. Specific abnormalities are seen by computed tomography or magnetic resonance imaging. Awareness of this syndrome is important for Emergency Physicians because visual loss can be reversible with prompt treatment of the underlying cause. ⋯ PRES should be considered in all patients presenting to the ED with visual loss, seizures, or headache, and can be recurrent in some individuals. Prompt treatment can help prevent permanent vision loss.
