[Prevention of viral infections transmitted by semen in volunteer donors for assisted reproduction. 2 years' experience].

During a 2 years period the serological markers of viral infections were evaluated in the semen of 24 donors who were involved in assisted reproduction techniques. The presence of cytomegalovirus, hepatitis B virus and human immunodeficiency virus were investigated. The results were as expected, no data of viral infection at the time of donation being found because the study population was a highly selected one. Taking into account all the known microorganisms that can be transmitted through semen, a protocol for the prevention of infections in the mother and in the prospective newborn is suggested.

Natural immunity to measles, rubella and mumps among Spanish children in the pre-vaccination era.

Prior to the start of mass vaccination campaigns against measles, rubella and mumps, a prevalence study of natural immunity to these diseases was undertaken in a sample of 1700 unvaccinated Spanish children. They were representative of the 3-7 year-old population in terms of age, regional distribution and urban or rural environment. Measles infection prevalence was significantly higher than that for rubella and mumps from 3 (48.3%, 14.2%, 25.5%, respectively) through 7 years of age, (64%, 40.9%, 39%). As a function of age, naturally-acquired immunity increased according to parabolic progressions. In the 3-5 year-old group, rural environment, low socioeconomic status, no school attendance and lack of brothers were associated with statistically lower levels of measles, rubella, or mumps infection. In the 6-7 year-old group, only 12% of the children showed antibodies against the three diseases and 18.7% exhibited triple susceptibility.

Three-year prospective study of intestinal pathogens in Madrid, Spain.

During the period July 1980 through June 1983, in a General Hospital in Madrid, the following organisms were detected from 6,970 patients with gastroenteritis: 710 Salmonella spp. 506 Campylobacter jejuni, 379 Shigella spp., 12 Yersinia enterocolitica, 1,466 rotavirus, 134 Giardia lamblia, and 4 Entamoeba histolytica. Chloramphenicol showed good activity against most tested strains of Salmonella spp., Shigella spp., and C. jejuni. The incidence of Salmonella spp. and Shigella spp. was very marked in the hot dry months of the year, rotavirus predominated during the cold months, and no seasonal variations of importance were seen for C. jejuni and G. lamblia.

[Campylobacter neonatal enteritis (author's transl)].

Authors communicate four cases of bloody diarrhea in neonates, with Campylobacter fetus jejuni in the stools. In one case, the same bacteria was isolated from the mother and, in another case, existed possibility of a cross-infection. The mildness of the evolution is marked, specially in those cases in which maternal feeding was continued. Some diagnostic and epidemiological aspects, concerning the neonatal period, are commented.
