The efficacy of mupirocin ointment and chlorhexidine body scrubs in the eradication of nasal carriage of Staphylococcus aureus among patients undergoing long-term hemodialysis.

BACKGROUND: Patients undergoing long-term hemodialysis have a high prevalence of Staphylococcus aureus nasal carriage, which may lead to serious infections. Mupirocin ointment has been used intranasally to eradicate S. aureus carriage in health human volunteers and health care workers. Chlorhexidine, an antiseptic with excellent antistaphylococcal activity, is widely used for handwashing and skin cleansing. METHODS: Anterior nares cultures were obtained from patients older than 18 years who were undergoing long-term hemodialysis. Patients with S. aureus nasal carriage were enrolled in the study. Axillae and groins were cultured. Patients were given mupirocin ointment intranasally twice per day for 7 days and chlorhexidine body scrubs daily for the first 3 days. Follow-up cultures were obtained from anterior nares, axillae, and groins at 1 day, and 1, 4, 8 and 12 weeks after treatment. RESULTS: One day after completion of treatment nasal carriage was eradicated in 83% of patients (15/18). After 12 weeks, 69% of patients (11/16) were free of nasal carriage. CONCLUSIONS: Success rates of eradication were excellent compared with those in other published reports. This simple and effective regimen had no major side effects.

The medical investigation of airship accidents.

A review of the autopsy reports for 18 of 21 victims in 3 of the 4 nonrigid Navy airship accidents during the period 1955 to 1966 revealed that the patterns of injury, complicated by postcrash entrapment, immersion, or fire, are similar to the injuries observed in the low-speed, low-altitude crashes of rigid airships and of light aircraft. With the renewed interest in the development of airships for military purposes, there is a need for improved design related to crashworthiness and to aircrew habitability, safety, restraint, and egress in order to enhance the chance for survival in the event of an accident.

The incident at Tuol Chrey: pathologic and toxicologic examinations of a casualty after chemical attack.

The results of the pathologic and toxicologic examinations of specimens from a casualty who died several weeks after a chemical attack in Kampuchea are discussed. While the effects of tricothecene mycotoxins have been described in domestic and experimental animals, there is a paucity of information about the pathologic effects of these toxins in humans. The possible effects of endemic diseases such as falciparum malaria, viral hepatitis, and nutritional deficiencies, as well as of the sudden, unexpected death syndrome among refugees from Southeast Asia, have been reviewed. If the results of the histologic examinations in this case are considered alone, it is not possible to establish a cause-effect relationship. However, the circumstances of injury, the relationship of pathologic findings to the studies of experimental animals, and the results of the toxicologic examinations of environmental and biologic specimens indicate that the combinations of tricothecene mycotoxins detected are not consistent with natural occurrence and provide evidence that the pathologic effects are related to a toxic agent.

Ballistic studies and lethal potential of tear gas pen guns firing fixed metallic ammunition.

Illegal older model and foreign-made tear gas pen guns as well as illicitly manufactured pen guns were used to fire revolver or pistol cartridges of calibers .22, .25, .32, .38, .44 Special, and .44 magnum, as well as rifle cartridges of caliber .270. Velocity, range of accuracy, impact kinetic energy, and gelatin block penetrability of bullets fired from the various cartridges are presented. The characteristics of recovered bullets, cartridge casings, and firing pin impressions are described, and the hazards of these weapons to users and potential victims are discussed.
