RESUMO
Mammary Paget's disease is one clinical expression of an underlying breast carcinoma. It manifests as persistent erythema, oozing and scaling of the nipple, areola or both. The occurrence of this disease in men is uncommon. This is a report of a pigmented lesion of Paget's disease occurring on the breast of a man. This presentation is unusual and may be confused with melanoma. Its early recognition is important so that adequate therapy may be instituted when the disease has a favorable prognosis

Available information indicates that antibiotic resistance is increasing throughout the world and that it is a greater problem in developing countries than in the more developed countries. A comparison of antibiotic susceptibility of gram negative aerobic bacilli from Holberton Hospital in St. John's, Antigua and Genessee Hospital in Rochester, New York, USA was undertaken to test that hypothesis. Escherichia coli, Klebsiella spp and Enterobacter spp isolates had antibiotic susceptibility tested by the disk diffusion method. Antibiograms of isolates from similar sources from both institutions from 1992 to 1995 were compared: ampicillin, gentamicin and cotrimoxazole. Results reveal that E. coli isolates in Antigua in 1992 had a higher prevalence of resistance to ampicillin (71 percent vs 31 percent, p=0.001) and no significant difference in resistance to gentamicin (4 percent vs 2 percent, p=NS) or co-trimoxazole (20 percent vs 11 percent, p=NS) compared to Rochester. By 1995, the prevalence of resistance was significantly greater for all three drugs (ampicillin 76 percent vs 31 percent, p=0.001, gentamicin 21 percent vs 2 percent p=0.001, co-trimoxazole 34 percent vs 9 percent, p=0.001) in Antigua compared with Rochester. Klebsiella and Enterobacter isolates in Antigua had a higher rate of resistance early and late compared with Rochester. Isolates from Holberton Hospital in Antigua developed a higher prevalence of resistance between 1992-3 and 1994-5, with E. coli having more resistance to gentamicin (4 percent vs 20 percent, p=0.01) and Klebsiella having more resistance to gentamicin (16 percent vs 43 percent, p=0.001) and co-trimoxazole (34 percent vs 57, p=0.001). In no instance did the resistance of any bacilli to any antibiotic improve significantly in that interval in Antigua. These data show that antibiotic resistance in Antigua is more prevalent than in Rochester and that the gap is widening.(AU)

Se investiga la susceptibilidad a la rubeola en 200 mujeres de un nivel socioeconomico alto, encontrandose que el 44% no tenian titulaciones por IH. El diagnostico clinico no fue corroborado por IH en el 55,5% de los casos que supuestamente padecieron de rubeola.Solo el 10,5% de la muestra, fue vacunada anteriormente, pero el 38,2% carecia de titulaciones por IH

The purpose of the study was to demonstrate that the supplementary effect of soybean protein to corn depends on the protein quality of the soybean product and of the corn products used. Four types of corn flour of different protein quality were used, which included two whole corn flours produced from common corn, one from Opaque-2 corn, and one from degerminated corn. Likewise, three soybean products were tested, including a solvent-extracted soybean flour, a texturized soybean product and a soybean protein isolate. The study was carried out with weanling rats and the effects were measured by PER assays. The results corroborated the hypothesis that the protein quality of the ingredients controls the response observed. The supplementary effects were more evident for low-quality corn flours. Furthermore, large increments in quality were observed with additions of 5% soy protein, which became smaller as this level increased, independent of the corn flour used.

Dietary intake information was collected on 2,426 rural and 5,828 urban men free of coronary heart disease in the Pureto Rico Heart Health Program. Serum cholesterol and triglyceride, body weights, and related parameters were measured during a detailed cardiovascular examination. There were statistically significant differences between rural and urban values with respect to lipids, relative weight, and intake of many nutrients. Rural subjects had lower lipids and relative weights. Serum cholesterol was associated with relative weight in both rural and urban areas. In the urban areas, serum cholesterol was associated with intake of total fat, saturated fatty acids, polyunsaturated fatty acids, total carbohydrate, and starch (all measured as percent of calories). It was also related to percent carbohydrate from starch and dietary cholesterol intake, even after relative weight was taken into account. The associations were of a low order, although statistically significant. The association of fasting triglycerides with some of the carbohydrate variables was statistically significant after relative weight was taken into account in the urban area. Overall, diet and relative weight can account for at most 6% of the variability in serum cholesterol observed, with at most 2.5% of the variability due diet alone.
