Placental abnormalities associated with human immunodeficiency virus type 1 infection and perinatal transmission in Bangkok, Thailand.

The effects of human immunodeficiency virus (HIV) type 1 on the placenta and the role of the placenta in mother-to-child HIV-1 transmission are not well understood. Placentas from 78 HIV-infected and 158 HIV-uninfected women were examined as part of a prospective perinatal HIV transmission study in Bangkok. HIV-infected women were more likely than HIV-uninfected women to have chorioamnionitis (odds ratio [OR], 2.1; P=.03), placental membrane inflammation (PMI; OR, 2. 7; P=.02), and deciduitis (OR, 2.3; P=.03) and less likely to have villitis (OR, 0.3; P=.02). However, among HIV-infected women, fewer women who transmitted infection to their child had chorioamnionitis (relative risk [RR], 0.2; P=.03), funisitis (RR, 0.4; P=.1), or PMI (RR undefined; P=.03). These findings suggest that, in this population, HIV-infected women are at increased risk for placental membrane inflammatory lesions, but that placental inflammatory lesions are not associated with increased perinatal HIV transmission.

Embryonic testicular regression syndrome: a case report.

A case of testicular regression syndrome was reported. The patient was an 18 year old girl presenting with primary amenorrhoea. Physical examination revealed normal female external genitalia and underdeveloped secondary sexual characteristics. Hormonal profile indicated gonadal failure. Chromosome analysis revealed 46,XY karyotype. Diagnostic laparoscopy demonstrated undeveloped internal genital organs. Remnants of epididymis, vas deferens and seminiferous tubule were uncovered during exploratory laparotomy. Ontogeny of sexual differentiation and pathogenesis of testicular regression syndrome were reviewed and discussed.
