RESUMEN
The aim of this work was to determine Giardia and Cryptosporidium levels in surface water used either as recreational or drinking water source, and to estimate the relationship with bacteriological and physicochemical parameters determining water quality. This study was carried out during 22 months, in Santa Fe and Santo Tomé cities (Santa Fe Province, Argentina). Cryptosporidium from 100% of the recreational samples (44-2404 oocysts/100 l) and from 92% of water sources (< 20-539 oocysts/100 l) was detected, while Giardia was found in lower concentrations and frequencies: 72% (< 20-670 cysts/100 l) and 31% (< 20-65 cysts/100 l), respectively. Statistically significant relationships were found between these parasites and organic matter, turbidity and bacteriological indicators of contamination (Escherichia coli, streptococci, Enterococcus spp, Pseudomonas aeruginosa). These relationships, however, vary according to the sampling place, the source and levels of contamination.

RESUMEN
Se presentan 120 casos de traumatismos del torax tratados entre agosto de 1978 y julio de 1982. Se destaca el alto porcentaje de casos con grave descompensacion cardiorrespiratoria al ingreso (46%), el alto numero de curaciones (115 casos, 95,8%) y el bajo numero de toracotomias de urgencia o tardias realizadas

En 7 casos con hernia hiatal comprobada radiologicamente se realizo centellograma esofagogastrico. Se describe la tecnica utilizada. En 6 se obtuvo evidencia centellografica de reflujo, mientras que la radiografia simple habia detectado 4. Resulta un metodo confortable para los pacientes ya que elimina el uso de la sonda nasogastrica
