Survival from acute renal failure after severe burns

We describe a patient with 50 per cent, third degree flame burns who had a history of paint thinner inhalation for over 10 years. Moreover, chlorpromazine had been administered for the treatment of insomnia caused by chronic thinner intoxication. He developed oliguric acute renal failure soon after the burn injury, although adequate resuscitation therapy was given, and survived following frequent haemodialysis. Although survival from acute renal failure after severe burns is rare, once the diagnosis of acute renal failure has been made, haemodialysis should be instituted as early as possible. Furthermore, in a severely burnt patient with episodes of chronic and acute intoxication from organic chemicals or drugs which may have caused renal damage, acute renal failure may occur, so that careful observation is advised.     

Hepatitis B exposure in emergency medical personnel: Prevalence of serologic markers and need for immunization

To assess the occupational risk of hepatitis B infection in emergency medical personnel, a seroepidemiologic survey of 87 emergency medical technicians and paramedics was conducted. Serologic markers indicating exposure to hepatitis B virus were detected in 18 percent. The prevalence of markers was associated with race (p = 0.006), with a relative risk of 3.5 (95 percent confidence interval 1.42 to 8.63) for nonwhites. Seropositivity was not associated with age, sex, previous clinical hepatitis, or blood transfusion. There was a suggestion that duration of employment as an emergency medical technician was related to the prevalence of hepatitis B markers (p = 0.11). Efforts to control the risk of hepatitis B infection in this profession are complicated by unique problems with postexposure prophylaxis and uncontrolled exposure to blood. Immunization with hepatitis B vaccine would be the optimal strategy to reduce infection in this high-risk occupation.     

Metastatic bronchogenic carcinoma masquerading as a felon

This report describes a rare occurrence of a subcutaneous metastatic bronchogenic carcinoma to the distal fingertip. The original clinical presentation suggested an infectious process. Subsequent roentgenograms, sterile cultures, and positive biopsy material revealed that the lesion started as a subcutaneous metastasis that secondarily involved adjacent bone. Amputation of the digit was performed.
