Rhabdomyosarcoma of the uterus: report of two cases, including one of the spindle cell variant.

Most uterine sarcomas fall into the category of leiomyosarcoma, endometrial stromal sarcoma, or undifferentiated sarcoma. Pure rhabdomyosarcomas are extremely rare, although a rhabdomyosarcomatous element may be present as a component of an adenosarcoma or carcinosarcoma (malignant mixed müllerian tumor). This report describes two uterine rhabdomyosarcomas in 28- and 67-year-old women.

Benign, borderline, and malignant endometrioid neoplasia arising in endometriosis in association with tamoxifen therapy.

Tamoxifen therapy may result in a variety of endometrial proliferative lesions, including adenocarcinoma, and as recently suggested, proliferative changes within endometriosis. This report describes an endometrioid adenocarcinoma arising in ovarian endometriosis in a patient taking tamoxifen. There were also foci of benign and borderline endometrioid adenofibroma in the same ovary and a synchronous endometrioid endometrial adenocarcinoma in the uterus.

Bilateral ovarian cysts with squamous intraepithelial neoplasia.

We report a case of bilateral ovarian cysts lined exclusively by squamous epithelium showing multifocal intraepithelial neoplasia. The cervix showed synchronous high-grade intraepithelial neoplasia (CIN III). We interpreted the ovarian lesions as squamous carcinoma of borderline malignancy and believe that they are part of a "field change" that also involves the cervix.

Pregnancy complicated by maternal heart disease. A review of 519 women.

Between 1970 and 1983, 519 pregnancies in 405 women with heart disease were managed at the Royal Maternity Hospital, Belfast, Northern Ireland, a rate of 1.3 per 100 deliveries. In 312 (60%) the heart disease was of rheumatic origin, in 161 (31%) congenital, and the remaining 46 (9%) were a miscellaneous group that included arrhythmias, ischaemic heart disease and cardiomyopathies.

The prognostic value in threatened abortion of plasma progesterone values and the cornification index of vaginal smears.

The predictive values of plasma progesterone levels in 70 patients threatening to abort was investigated. It was found that no patient aborted whosed plasma progesterone level remanined above 35 nmol/l between 7 and 16 weeks of pregnancy, whereas if the plasma progesterone level was less than this, subsequent abortion always occurred. The predictive value of cornification index in vaginal smears was also examined: many smears were unsatisfactory for assessment and in patients with threatened abortion there was a 14 per cent incidence of falsely optimistic and 29 per cent of falsely pessimistic predictions.

A study of plasma diazepam levels in mother and infant.

A 10 mg dose of diazepam was given intravenously to mothers at 15 to 205 minutes before delivery, and plasma diazepam concentrations were measured by gas-liquid chromatography in mothers and infants at delivery and again 24 hours later. The plasma levels in the infants were always significantly higher than in the mothers but there was no evidence to suggest that the newborn were unable to metabolize the drug. All infants had a good Apgar score at birth.
