There was no history of cardiac, respiratory, gastrointestinal, or urinary symptoms.\n\nHector mistrusts \u201callopathic\u201d medicine and relies on homeopathy. His homeopathic practitioner prescribed a one-week course of chamomile drops at the start of his illness. Hector\u0027s symptoms continued to persist; and finally, his brother persuaded him to visit your hospital.\n\nHector\u0027s medical, surgical, and family histories are unremarkable. His allergic history is significant for allergy to penicillin. His social history is significant for intravenous (IV) drug abuse for 3 years, predominantly heroin and cocaine. He claims to have been drug free for the past 6 months after the pastor of his church helped him \u201cfind his true path\u201d.\n\nHector has a single stable female sexual partner. He has had a total of 4 different partners over the years. He was persuaded to undergo HIV testing 3 months ago, which was negative. He has a 10-pack-year smoking history. He has also consumed alcohol regularly since the age of 21, with an estimated consumption of 3 to 4 units per week, on average.\n"}]}

General examination was significant for multiple old needle marks on both arms and thighs; grade 2 clubbing of all fingers and toes; darkened linear streaks running from the tip to the nail bed of the right second finger and left second and third fingers; and multiple small painless erythematous lesions on the soles of both feet. \n\nCardiovascular examination revealed a grade 3\/6 holosystolic murmur that was loudest over the left lower sternal border. Abdominal, respiratory, and central nervous system examinations were normal.\n"}]}
