RESUMO
We assessed myocardial perfusion (blinded interpretation of a single-photon emission computed tomography) and known risk factors for atherosclerosis in 105 randomly selected human immunodeficiency virus (HIV)-infected patients in a clinic in Mexico City and in a community sample of 105 age and gender-matched infection-free subjects. An abnormal scan was obtained in 4.8% of the infected and in 7.6% of the non-infected subjects. Severity of scintigraphic abnormalities was similar in both groups. In these Mexican HIV-infected patients, despite a long time of infection and of exposure to combined antiretroviral therapy and to other classical risk factors for atherosclerosis, there was no evidence of increased risk for abnormal myocardial perfusion. Dissimilar magnitude in the hazard of coronary heart disease may occur among infected populations with different frequencies of traditional predisposing factors for cardiovascular illness.

BACKGROUND/PURPOSE: To report a case of toxic epidermal necrolysis (TEN) involving 90% body surface area, successfully treated with a nanocrystalline silver dressing (Acticoat, Smith & Nephew, Largo, FL). METHODS: A review of the hospital and acute wound center patient records and the recent English medical literature regarding TEN and nanocrystalline silver dressing. RESULTS: We found only 1 report of TEN treated with a nanocrystalline silver dressing. The nanocrystalline silver dressing was both effective in preventing wound infection and convenient for treating our patient with TEN. CONCLUSION: The use of nanocrystalline silver dressing should be considered for the treatment of TEN.
