RESUMEN
Inguinal hernias were diagnosed at 42 and 38 weeks' postconceptional age in 2 premature girls. The hernial sac contained the uterus, one Fallopian tube, and one ovary. The diagnosis was made by physical and sonographic examination and was confirmed during surgical correction. We suggest sonography in the diagnostic workup in (premature) female infants with an inguinal hernia.

When the H1N1 subtype of influenza reappeared in the Northern Hemisphere during 1977, after a 20-year absence, it behaved very differently from the H3N2 subtype still in circulation. In Sydney, we studied the incidence of both subtypes of laboratory-proven influenza type A in 287 unvaccinated volunteers whose serum antibody titres were measured before and after each winter, to facilitate the detection of subclinical as well as clinical infection. During a 1977 epidemic, the A/Victoria/3/75 strain of the H3N2 subtype attacked participants of all age groups, whereas during epidemics of 1979 and 1981, the A/USSR/90/77 and A/Brazil/11/78 strains of the H1N1 subtype attacked only subjects born after 1950. The older participants apparently possessed homologous protection, acquired as a result of exposure to H1N1 more than 20 years earlier and not dependent upon strain-specific haemagglutination inhibition antibody.
