ABSTRACT
La hernia incisional es una complicación frecuente de la cirugía abdominal y una importante fuente de morbilidad. A pesar del creciente progreso de la cirugía moderna, el tratamiento quirúrgico óptimo de esta entidad es aún un problema no resuelto. Cuando se realiza un análisis de la literatura se encuentra gran cantidad de información con este tema; pero no es posible encontrar un tratamiento globalmente estandarizado. En la actualidad se utilizan diferentes y variadas técnicas de hernioplastias tales como la sutura simple, cierre con técnica de Mayo, utilización de prótesis en forma abierta o laparoscópica, siendo estas últimas las que presentan las menores tasas de recidiva, haciéndolas aparecer como la alternativa más recomendable en el tratamiento de esta patología.

Evaluation of desinsectation programs carried out in the two Health Services from the V Region, was undertaken by comparing serologic prevalences of T. cruzi infection age groups exposed to the risk of infection in rural areas during the antivectorial campaign activities (1982 vs 1995). Thus, were studied 2,193 blood samples from children under 10 years of age, proceeding from six chagasic endemic provinces in which antitriatomic domiciliary insecticide sprayings had been performed. Indirect hemagglutination and ELISA tests were carried out to each of the blood samples. A total de 42 (1.9%) children resulted positive. As in five counties no positive cases were detected in the last five years it is possible to assume that vector transmission of T. cruzi should have been interrupted in them. When comparing prevalences existing in 1982 with the present ones, it is possible to observe a 63.5% of reduction of transmission in the V Region, been this reduction higher in the Aconcagua Health Service with 79.6% and lower in the Viña del Mar--Quillota Health Service with 55.6%. According to these results, comparison of prevalence of T. cruzi infection in children less than 10-year-old in diverse periods, allows evaluate the vectorial control of Triatoma infestans programs.

In order to contribute to the knowledge of intestinal parasite infection a survey was performed in 462 primary school children from eight rural localities sited in two islands of the Chiloe archipelago. Stool samples and perianal scotch tape scrapings for intestinal protozoa and helminths were microscopically examined. The prevalence rates of the main species found were: Ascaris lumbricoides 43.3%, Trichuris trichiura 26.8%, Enterobius vernicularis 20.1%, Entamoeba histolytica 5.6%, Giardia intestinalis 20.6% and Blastocystis hominis 63.2%. Poverty, deficiencies in hygienic practices and poor basic environmental sanitation are the contributing factors in the maintenance of the high prevalence of the intestinal parasitic infections found. A health education program, improvement of basic sanitary conditions and eventual treatment of infected people may contribute to control this undesirable situation.
