RESUMEN
Penile and/or genital involvement may be an early manifestation of AIDS-related Kaposi sarcoma. Diagnosis may be suggested by history, and epidemiologic and sociologic data. Precise diagnosis can be documented by the urologist by early recognition and biopsy of genital lesions. Early awareness and treatment may control this potentially virulent disease.

The radiographic appearance of the hydronephrotic upper urinary tract due to congenital ureteropelvic junction obstruction may not return to normal even though the obstruction is relieved by surgical repair. We present a case of ureteropelvic junction obstruction in which the success of the repair was demonstrated dramatically only by diuretic radionuclide urography.

Residues of DDT (1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane) were measured quarterly during 1983-84 in bottom sediments and benthic macroinvertebrates from heavily contaminated sections of Huntsville Spring Branch (HSB) and Indian Creek (IC), backwater streams on Wheeler Reservoir (Alabama). Bottom muds from both channel and overbank locations contained mean concentrations of DDTR (DDT and its metabolites) ranging from 12 to 2,730 ppm (dry weight). Sediment DDTR were highest in HSB at stations closest to the original DDT source. Stations in IC, downstream from HSB, had progressively lower DDTR as distance from the DDT source increased. Macroinvertebrate DDTR measured from several stations suggested bioaccumulation of residues mainly through food webs; however, at the most contaminated locations, substrate and mode of life appeared to override trophic level effects in determining DDTR in the benthos. There is apparently an upper limit to the amount of DDTR these organisms usually accumulate. For example, detritivore DDTR from channel sediments at two stations just downstream from the DDT source averaged 125.1 and 157.9 ppm, respectively, although sediment DDTR at these two sites averaged 2,730 ppm and 96 ppm, respectively. Benthic macroinvertebrates in the highly contaminated sediments of HSB and IC apparently acquire DDTR from water, sediments, and food.

How are government controls affecting healthcare foodservices?Are growing elderly & outpatient populations changing foodservices' missions. What are the hottest trends? As members of the American Society for Hospital Food Service Administrators prepared for their annual meeting in Orlando, FM queried 11 Southeastern directors to learn their most pressing concerns & how they are positioning their departments for the future.
