Nosocomial varicella. Part I: outbreak in oncology patients at a children's hospital.

Twenty cases of varicella occurred in patients or siblings of patients in a 41-day period in a children's hospital. Most cases were among oncology patients, with transmission occurring in both the inpatient and outpatient areas. One patient died after visceral dissemination of varicella. Neither pooled immunoglobulin nor zoster immune plasma was effective in preventing clinical varicella, although zoster immune plasma appeared to ameliorate the illness. Recommended control measures included strict isolation or discharge of infected patients, and respiratory isolation or discharge of exposed susceptibles. Although apparently too late to be effective in this outbreak, similar measures are warranted should nosocomial outbreaks of varicella occur elsewhere.

Diagnosis and treatment of Amanita phalloides-type mushroom poisoning: use of thioctic acid.

The number of cases of mushroom poisoning is increasing as a result of the increasing popularity of "wild" mushroom consumption. Amanitin and phalloidin cytotoxins found in some Amanita and Galerina species produce the most severe and frequent life-threatening symptoms of Amanita phalloidestype poisoning. Delay in onset of symptoms, individual susceptibility variation and lack of rapid and reliable identification have contributed to the significant morbidity and mortality of this type of poisoning.A rapid chromatographic assay for identifying the potent cytotoxins and apparently successful management using thioctic acid of two cases of A. phalloides-type mushroom poisoning are reported. All known cases of A. phalloides-type mushroom poisoning treated with thioctic acid in the United States are summarized.

Pulmonary air leaks resulting from outdoor sports. A clinical series and literature review.

The occurrence of pulmonary air leaks consequent to recreational sports is considered to be rare. We performed a retrospective records review for cases of pulmonary air leaks for the 5-year period 1993 to 1997 at a community hospital that serves a popular tourist destination area having intense year-round outdoor recreational activities. We identified 20 patients who had sustained a spontaneous or traumatic pulmonary air leak while engaged in an outdoor sport. All but one case (95%) were due to blunt chest trauma. A total of nine different sports were involved, but the majority of cases (11, or 55%) occurred during skiing or snowboarding. Three (15%) patients died. Nine (53%) of the surviving 17 patients sustained injuries serious enough to require hospitalization for tube thoracostomy and other trauma care. We concluded that pulmonary air leaks due to blunt chest trauma occur more frequently in outdoor sports than the literature suggests.
