A Disease Scattered to the 4 Winds

Publish Date

In 2013, a mother arrived at a Texas clinic with her 4-year-old son in tow. Three weeks earlier, he had been diagnosed with ringworm and given an antifungal (griseofulvin), but he had recently stopped eating. Concerned about his loss of appetite, she patiently waited for a doctor to see her son. When the doctor finally saw them, she informed him that it had been 2 days since her son ate. He also had begun to develop a rash on his face, trunk, and extremities and had some nasal congestion and an occasional cough. The doctor conducted a physical exam on the boy but there was nothing extraordinary other than his presenting symptoms: a sand paper–like erythematous rash and reddish mucosal tissue in his mouth and throat. He wasnt feverish, his cough was not persistent, and a rapid strep test was negative. Believing he had contracted a virus, the doctor sent him home to rest.

Death During Sex

Publish Date

Over-activity of the sympathetic nervous system (which controls ejaculation as well as the actions of the heart and blood vessels) can bring on sudden death due to cardiac arrest during or shortly after sexual activities. In 2011, Dr. Issa Dahabreh, affiliated with Tufts Medical Center in Boston, conducted an analysis of 14 studies along with a colleague, Jessica Paulus, to quantify the risk of having a heart attack or sudden cardiac death brought about by sex. The team of doctors discovered that people are 2.7 times more likely to have a heart attack either during or shortly after sex compared to when they are inactive. However, they point out that the period of risk is brief, that is, either during the act itself or about 1 to 2 hours after sexual activity. They go on to report that individual risk is minimal. The researchers further highlight the fact that other studies have shown that regular physical activity reduces the risk of heart attacks or sudden cardiac death by 30%.
