RESUMO
Se discute el estado actual del conocimiento sobre los cuadros clínicos de eosinofilia por helmintiasis parenteral, quedando aquí englobados los síndromes de Löeffler, eosinofilia tropical, granulomatosis larvaria, endoftalmitis por nemátodos y de Friess-Pierrou. Se revisan los posibles diagnósticos etiológicos en estos pacientes. Se presenta el caso de una niña de 18 meses de edad con gran eosinofilia y hepatomegalia, en la que se encontró una larva de 427 µ de largo en el hígado. Se determinó que la larva no corresponde a un parásito habitual del hombre ni a parasitos de animales que ya se hayan encontrado en el hombre. Se opinó que tal larva puede ser un nemátodo parásito de plantas o de insectos, o quizá del género Logibucca, parásito de serpientes y murciélagos. Sea cual sea su posición taxonómica, agranda enormemente las posibilidades etiológicas del síndrome aquí estudiado

A study was made of the viability of Cysticercus cellulosae at different temperatures. It was found that the type of casing did not affect survival, but that the parasites remained alive longer in large cuts of meat. Data are given on the survival of cysticerci at various temperatures. The recommended method of destruction, which does not affect the characteristics of the meat, is refrigeration at -20 degrees centigrades for not less than 12 hours. This procedure is more advantageous than frying, the method presently employed, and it can be financially beneficial to the meat industry. Furthermore, if it were compulsory as a prophylactic measure for all pork, it would prevent teniasis and cysticercosis in humans, because it would destroy the parasites in meat which, because it is only slightly infested, passes as wholesome at meat inspections
