Staphylococcal necrotizing fasciitis in the mammary region in childhood: a report of five cases.

Objective: Necrotizing fasciitis is a highly lethal soft tissue infection rarely reported in childhood. The initiating site is usually a local trauma or a surgical wound. We observed five cases of necrotizing fasciitis the initiating site for which was the mammary region and discuss their management.

[The immotile cilia syndrome. A rare form of male infertility].

A man presented with 100% immotile spermatozoa. Transmission electron microscopy showed the absence of both central tubules in all sperm tails; the nine peripheral tubules, dynein arms, radial spokes and other structures of the sperm tail were normal. Immotile cilia syndrome of the 9 + 0 tubular pattern was diagnosed.

Adherence of Escherichia coli to sperm: a mannose mediated phenomenon leading to agglutination of sperm and E. coli.

Objective: To investigate the mechanism of adherence between Escherichia coli and sperm.

Design: Experimental study performed with donor sperm and male genital tract-derived E. coli.

Comparison of three methods to detect white blood cells in semen: leukocyte esterase dipstick test, granulocyte elastase enzymeimmunoassay, and peroxidase cytochemistry.

Comparison of three methods for the detection of WBC in semen revealed a low concordance of positive test results. Among 557 semen samples, most positives were observed with the leukocyte esterase dipstick test (n = 95; 17.1%) followed by the peroxidase test (n = 51; 9.
