The association of anovulation and endometriosis in the infertile female.

Ninety-six infertile patients with endometriosis were studied and their endometriosis staged according to the Revised American Fertility Society Classification. Anovulation was detected in 19% of the 32 patients with Stage 1 disease but in only 3% in the remaining 64 patients with Stage II, III and IV disease. These results show that contrary to traditional belief, anovulation does occur in a significant number of patients with endometriosis, especially in minimal or mild disease.

Maternal height, birthweight, obstetric conjugate and their influence on the management of parturients with a previous cesarean scar.

A retrospective analysis was made of the second deliveries of 492 women who had previously undergone emergency cesarean section with a clinical indication of cephalopelvic disproportion and had undergone X-ray pelvimetry. In their index (second) pregnancy, 234 (47%) had an elective cesarean section; 122 (25%) gave birth vaginally and 136 (28%) had undergone an emergency cesarean section. Maternal height had a moderate value as a surrogate measure of pelvic capacity. A trial labor was more often allowed in women with larger obstetrical conjugate (inlet) measurements but likelihood of a successful outcome of labor was not influenced by the above pelvic measurements. A baby weighing more than 4000 g was associated with a greatly reduced chance of a vaginal delivery. The study confirms the limitations of X-ray pelvimetry measurements and proposes that antenatal estimation of fetal size may be of benefit in determining the likelihood of success in a trial labor.

The accuracy of measurements of ovarian follicular scanning by inexperienced observers using real-time sector scanning.

Three inexperienced operators (2 midwives and one obstetric registrar) were given ten sessions of training in ovarian follicular scanning. During each session, five patients were examined jointly. Once the inexperienced observers had received sufficient training the prospective study was started. Twenty measurements by each inexperienced observer were compared to measurements made by an experienced observer. In 17% of measurements the error was greater than 3 mm, the errors being evenly distributed among the three observers. After a further five sessions of instructions, another set of sixty measurements was generated: 93% of these measurements correlated exactly among the inexperienced operators and between the inexperienced and the experienced operator. This study suggests that after a supervised training of 15 sessions, obstetricians and midwives with prior obstetric scanning experience can produce reliable ovarian follicular measurements.

A prospective comparative study of transvaginal ultrasonography and digital examination for cervical assessment in the third trimester of pregnancy.

Digital examination of the cervix has traditionally been the "gold standard" for cervical assessment. However, it can be subject to inter- as well as intra-observer variation. The usefulness of transvaginal ultrasonography for cervical assessment is examined in this study. Although differences between measurements of transvaginal ultrasonography and digital examinations were observed, transvaginal ultrasonography appears to be a potentially useful and reproducible technique for assessing cervical changes in pregnancy and for prediction of onset of labor.

Maternal height, shoe size, and outcome of labour in white primigravidas: a prospective anthropometric study.

A total of 563 white primigravid patients at Raigmore Hospital, Inverness, were recruited in a prospective study to examine the association between maternal height, shoe size, and the outcome of labour. There was a significantly increased caesarean section rate in women of short stature but no association between mode of delivery and shoe size. Babies born vaginally had heavier birth weights with increasing height and shoe size. Babies born by caesarean section were heavier than those born vaginally, but their birthweight showed no relation with either height or shoe size. Shoe size is not a useful clinical predictor for the probability of cephalopelvic disproportion, and, although maternal height is a better clinical guide to pelvic adequacy in labour, 80% of mothers less than 160 cm tall delivered vaginally. A well conducted trial of labour should be considered in all primigravid patients with cephalic presentation irrespective of maternal height or shoe size if no obstetric complication exists.
