Turner's syndrome with sex chromosome mosaicism.

The increased risk of gonadal neoplasia in cases of Turner's syndrome with sex chromosome mosaicism and the presence of Y chromosome material emphasises the need for a diligent search and removal of the streak gonads. One such case is reported here.

Abortion due to infection with Chlamydia psittaci in a sheep farmer's wife.

A farmer's wife who had helped with lambing aborted spontaneously in March after a short febrile illness in the 28th week of her pregnancy. She developed disseminated intravascular coagulation post partum with acute renal failure and pulmonary oedema. Recovery was complete after two weeks of hospital care.

Postpartum decline in serum concentration of placental proteins in an abdominal pregnancy.

The alpha and the beta forms of Schwangerschaftsprotein 1 (SP1) and chorionic gonadotrophin (hCG) were measured after delivery in an abdominal pregnancy with the placenta left in situ. All three proteins declined more slowly than after normal delivery; the half-lives ranging from 6.2-6.

Measurement of plasma placental proteins and estriol in the detection of intrauterine growth retardation.

This study was designed as an assessment of the clinical value of total estriol, placental lactogen (hPL), pregnancy specific glycoprotein (SP1), pregnancy-associated plasma protein-A (PAPP-A) and placental protein 5 (PP5), measured in a single sample of maternal serum, in the detection of intrauterine growth retardation (IUGR) in a large series of high risk pregnancies. Our results show the highest detection rate with SP1 (51%) and second highest with hPL (35%); estriol was less useful while PAPP-A and PP5 were of no value. However, there was 31% of false positives with SP1 compared with 14% for hPL.
