[Dysgenetic male pseudohermaphroditism].

Dysgenetic male pseudohermaphroditism is the result of a defect of testis development that encompasses a large clinical heterogeneity. It is characterized by bilateral dysgenetic testis, absence of mullerian regression, ambiguous genitalia and/or stigmata of Turner's syndrome in the majority of the cases. Typically, these individuals have either a 46,XY or 45,X/46,XY karyotype. The authors present four cases of dysgenetic male psudohermaphroditism, with ages of diagnosis between 1 month and 17 years old. The first had a male phenotype with stigmata of Turner's syndrome and the others ambiguous genitalia. Two patients were 45,X/46,XY and 45X/47,XYY mosaics and the other two were 46,XY. Gonadal karyotyping showed mosaicism (45,X/46,XY) in all four cases. In the first case was programed orquidectomy; all the others assigned a male gender, with regular follow-up until the puberty.

Cryptosporidium, isospora and strongyloides in AIDS.

BACKGROUND: Diarrhoea is a common presentation in patients with AIDS. It occurs due to a number of parasites which are seldom seen in immunocompetent hosts. METHODS: Between January 1993 and July 1994, faecal specimens from 77 patients with AIDS presenting with diarrhoea of more than a month's duration were examined by direct wet mount microscopy of saline and iodine preparations and by the modified Ziehl-Neelsen stain. RESULTS: Cryptosporidium, Isospora and Strongyloides stercoralis alone or in combination were present in 29 of the 77 patients. CONCLUSION: The presence of these parasites highlights their pathogenic potential for immunocompromised patients with AIDS. Diarrhoea due to Isosporais responsive to treatment, hence their identification has therapeutic implications as well.

A pilot programme of MRSA surveillance in India. (MRSA Surveillance Study Group).

This surveillance study was conducted simultaneously at three centres across India. A total of 13,610 test samples from various sites were obtained. Microbiological methods employed were similar at the three centres. Identification of S aureus was based on the recognition of the production of coagulase with positive isolates being recorded as S aureus. Both tube coagulase tests and slide coagulase test were performed. Antimicrobial susceptibility testing of the isolated strains of staphylococcus aureus and staphylococcus epidermidis to various antimicrobial discs were carried out according to standardized disk diffusion method recommended by NCCLS. Of the total 739 cultures of S aureus, 235 (32%) were found to be multiply resistant with the individual figures for resistance being 27% (Bombay), 42.5% (Delhi) and 47% (Bangalore). MRSA is emerging to be a significant problem pathogen in the surgical setting with vancomycin probably the only reliable choice for these infections.
