RESUMEN
La utilización del estimulador vagal constituye una alternativa válida de tratamiento paliativo en aquellas epilepsias refractarias que no pueden ser tratadas mediante técnicas quirúrgicas a cielo abierto (lobectomias, lesionectomías, desconexiones). Se describen fundamentos del procedimiento, indicaciones del mismo, técnica quirúrgica y experiencia de los autores.

The purpose of this study was to determine if there are racial differences in the blood pressure patterns among urban adolescents. Blood pressure (BP) was measured according to Task Force guidelines in health-screening and education sessions conducted in urban public and parochial high schools. The prevalence of BP > or = 95th% (HBP) on initial screening was determined in a population of 3,349 students. Differences in prevalence of HBP among race, sex, and age groups were tested for significance by chi 2 analysis. The overall prevalence of HBP in this urban adolescent population was 8.1%. Significant race differences were present in females (blacks = 6.6% versus non-Hispanics = 2.9%, p < 0.01). Within the black females, HBP occurred more frequently among the girls attending predominantly black public schools (7.7%) compared to an interracial parochial school (2.0%) p < 0.001. This difference could not be explained by weight, height, or the occurrence of obesity. The observed BP differences within black females, by school, may reflect a family-environment effect on cardiovascular risk.

In conjunction with an ecological study of jaguars in the Cockscomb Basin of Belize, Central America, fecal samples from jaguars (Panthera onca), jaguarundis (Felis yagouaroundi), ocelots (Felix pardalis), and pumas (Felix concolor) were examined for parasite products (eggs, larvae, and oocysts). Of the 45 samples examined, 39 (86.7%) were positive for parasite products, 23 of 25 (92%) jaguar samples were positive, as were all of the puma (4/4) and ocelot (8/8) samples. Four of 6 samples from unknown species were positive (66.7%). Two jaguarundis samples were negative. The following were identified in the samples: Paragonimus sp. eggs, Taeniidae eggs, Strongylate eggs, Toxocara cati eggs, Toxascaris sp. eggs, Capillaria sp. eggs, Spiruridae eggs, Aelurostrongylus sp. larvae, Oncicola sp. eggs, Hammondia pardalis oocysts, Isospora sp. oocysts, Toxoplasma gondii-like oocysts and Sarcocystis sp. sporocyst.
