Comparison of silver sulfadiazine and gentamicin for topical prophylaxis against burn wound sepsis.

Daily prophylactic application of either 1.0% silver sulfadiazine cream or 0.1% gentamicin cream was compared for effectiveness in preventing bacterial colonization of burn wounds and sepsis. Pseudomonas aeruginosa colonized the wounds of 37% of the 38 patients treated with silver sulfadiazine and 30% of the 33 patients treated with gentamicin; gentamicin-resistant P. aeruginosa colonized the wounds of 21% of the patients treated with gentamicin. Staphylococcus aureus colonization occurred in 55% of the patients treated with silver sulfadiazine, whereas colonization with Candida species occurred in 58% of the patients treated with gentamicin. Although gentamicin-resistant organisms caused no deaths their repeated appearance resulted in discontinuation of prophylaxiz with gentamicin cream. The next year P. aeruginosa strains resistant to gentamicin were isolated from burn wounds of only two patients who had not previously received parenteral therapy with gentamicin or tobramycin. Gentamicin cream should be reserved for treating patients with wounds infected by gentamicin-sensitive P. aeruginosa and those allergic to sulfa drugs. For most patients with burn wounds silver sulfadiazine is safe and effective as an antibacterial agent for topical prophylaxis.

Perspectives of radioactive contamination in nuclear war.

The degrees of risk associated with the medical, industrial and military employment of nuclear energy are compared. The nature of radioactive contamination of areas and of persons resulting from the explosion of nuclear weapons, particularly the relationship between the radiation exposure and the amount of physical debris, is examined.Some theoretical examples are compared quantitatively. It is concluded that the amount of radio-activity that may be carried on the contaminated person involves a minor health hazard from gamma radiation, compared to the irradiation arising from contaminated areas.

Abomasal ulcers in captive white-tailed deer (Odocoileus virginianus).

Abomasal ulceration was noted in 32 of 200 white-tailed deer. Ulceration was most common in the abomasal pylorus and at the abomasal-duodenal junction. Abomasal ulceration was characterized by focal to multifocal, sharply demarcated areas of coagulation necrosis and haemorrhage extending through the mucosa, with fibrin thrombi in mucosal blood vessels of small diameter. Ulcerated areas were often covered by a mixture of mucus, debris and neutrophils. Visible bacteria were not associated with ulcerative lesions. All deer with abomasal ulceration had intercurrent disease, including bacterial pneumonia, enterocolitis, intussusception, chronic diarrhoea, capture myopathy, or experimentally induced tuberculosis. The anatomical distribution of abomasal ulcers in this population of captive white-tailed deer resembled that seen in veal calves.
