Medroxyprogesterone acetate in the treatment of pelvic pain due to venous congestion.

Ovarian function was suppressed with 30 mg of medroxyprogesterone acetate, daily for 6 months, in 22 women with lower abdominal pain due to pelvic congestion. There was reduction in pelvic congestion demonstrated by venography in 17 of the 22 women, and in 16 this was associated with induction of amenorrhoea which suggests that effective ovarian suppression is an important component of successful treatment. In the 17 women who showed a reduction in venogram score, the median change in pain score was 75% compared with only 29% in the five women with no change in venogram score (P less than 0.01). This significant association between reduction in pelvic congestion and pain indicates that pelvic congestion is likely to be the cause of pain in these women and that treatment with medroxyprogesterone acetate could be of value.

A randomized controlled trial of medroxyprogesterone acetate and psychotherapy for the treatment of pelvic congestion.

The value of medroxyprogesterone acetate (MPA) and of psychotherapy in the treatment of lower abdominal pain due to pelvic congestion was assessed in a randomized controlled trial. Eighty-four women with abnormal pelvic venography were assigned to one of four treatment groups: MPA alone, MPA plus psychotherapy, placebo alone, and placebo plus psychotherapy. Women were treated for 4 months and thereafter followed up regularly for 9 months with pain assessments, pelvic ultrasound scanning, and hormone measurements. During treatment, MPA showed a significant benefit in terms of a reduction in visual analogue scale pain score, with 73% of women reporting at least 50% improvement compared with 33% of those treated with placebo. At 9 months after the end of therapy there was no overall significant effect of MPA or psychotherapy, but there was an interaction between MPA and psychotherapy, with 71% of the women in this group showing a greater than or equal to 50% reduction in pain score. Therapy with MPA is a useful first-line therapy for women with pain associated with demonstrable pelvic congestion.

Doppler ultrasound in the nonpregnant pelvis.

The reproducibility of Doppler ultrasound waveforms within gynecology has not been previously assessed. A study was conducted of Doppler ultrasound signals from the uterine and ovarian arteries in nonpregnant women. The aim of the study was to compare the results of two different observers and also to determine the influence of a time delay (30 minutes later). A second aim was to observe the influence of the menstrual cycle on Doppler ultrasound signals. Pulsatility indices were calculated for each series of Doppler signals. The results show that the technique has a large interobserver difference and its use in the deep pelvic vessels for research purposes is of doubtful value at present.

Factors predisposing to and outcome of gestational diabetes.

Two hundred thirteen women with abnormal glucose tolerance tests (GTTs) were diagnosed over 9 years by a screening program involving the total antenatal population. Each subject was matched for age, parity, and ethnic group with a control. The gestational diabetics were subdivided into classes A1 or A2 based on the fasting plasma glucose value of their GTT: A1 when below 6.0 mmol/L (108 mg/dL) and A2 when 6.0 mmol/L (108 mg/dL) or higher. All received treatment with dietary advice and some with insulin. Birth weight was not related to maternal age or severity of diabetes, but was related to maternal obesity. However, neonatal morbidity indices such as admission to the special care baby unit for longer than 48 hours and polycythemia (hematocrit above 65%) were related significantly to the severity of the diabetes and not to maternal age or obesity.

Interrelationships among abnormal cardiotocograms in labor, meconium staining of the amniotic fluid, arterial cord blood pH, and Apgar scores.

A prospective study of the relationships among fetal heart rate pattern, meconium staining of the amniotic fluid, umbilical cord artery pH, and Apgar score was carried out in 1219 consecutive births. Interpretable cardiotocogram patterns and cord arterial pH and blood gas analysis were obtained in 698 cases. The sensitivity of an abnormal cardiotocogram at any time for acidosis (more than 1 SD below the mean, pH less than 7.17) was 80%, and for severe acidosis (more than 2 SDs below the mean, pH less than 7.085) was 83%. However, the predictive value was low, and 32% of fetuses had an abnormal cardiotocogram but no acidosis. If only cardiotocogram abnormality in the first stage of labor was considered, sensitivity was still 47% for acidosis and 67% for severe acidosis, and the false-positive rate was reduced to only 14%. We attempted to improve the prediction of acidosis by including meconium staining of the amniotic fluid, but 65% of the variation in umbilical cord artery pH and 72 and 86% of the variation in 1- and 5-minute Apgar scores, respectively, remained unexplained. In light of these poor correlations, the current practice of considering cardiotocogram abnormality, meconium staining of the amniotic fluid, acidosis, and low Apgar scores as indicating one single disorder, "fetal distress," is not valid.

Validation of thermal techniques for measurement of pelvic organ blood flows in the nonpregnant sheep: comparison with transit-time ultrasonic and microsphere measurements of blood flow.

Data obtained from a thermal system capable of measuring changes in organ temperature as well as tissue thermal clearance in the uterus and vagina have been compared with blood flow measured continuously with a transit-time ultrasound volume-flow sensor placed around the common internal iliac artery and intermittently with radioactive microspheres in the chronically instrumented nonpregnant sheep. Temperature changes in both the uterus and the vagina correlated well with blood flow changes measured by both techniques after intravenous administration of estradiol or norepinephrine. Thermal clearance did not correlate well with blood flow in the vagina or uterus. These methods may have value in the investigation of blood flow patterns in various clinical situations such as the pelvic pain syndrome and early pregnancy.

Clinical features of women with chronic lower abdominal pain and pelvic congestion.

The clinical features of 35 women with pelvic pain and demonstrable congestion on pelvic venography have been characterized by comparing their symptoms and signs with those of 22 women with pelvic pain due to classical pathology. Women with pelvic pain and congestion had a mean age of 32.4 years, were more often multiparous and had had symptoms for 6 months to 20 years. The pain was dull and aching with sharp exacerbations. In individual women it commonly occurred on one side of the abdomen but unlike the pain due to 'classical pathology', it could occur on the other side. The pain was exacerbated by postural changes, and walking. Congestive dysmenorrhoea, deep dyspareunia and postcoital ache were common findings in women with pelvic congestion and 60% had evidence of significant emotional disturbance. The combination of tenderness on abdominal palpation over the ovarian point and a history of postcoital ache was 94% sensitive and 77% specific for discriminating pelvic congestion from other causes of pelvic pain.

Intravenous dihydroergotamine to relieve pelvic congestion with pain in young women.

The selective venoconstrictor dihydroergotamine (DHE) was given intravenously to 12 women with evidence of pelvic congestion. In 6 the effect of the drug on pelvic veins was observed by pelvic venography. After DHE there was a mean reduction of 35% in the diameter of the pelvic veins measured and the contrast medium cleared rapidly, with a visible reduction in pelvic congestion. In the other 6 women DHE was given during an acute attack of pelvic pain. The effect of the drug on pain relief was assessed by a single-blind crossover trial with intravenous saline as the placebo and by a visual analogue scale to assess the intensity of pain. Pain was significantly lower post-DHE 4 and 8 h and 2 and 4 days after treatment than after placebo. The results confirm a close association between demonstrable pelvic congestion and pelvic pain.

Outcome of pregnancies progressing beyond 28 weeks gestation in women with a history of recurrent miscarriage.

Ninety-seven women who had had three or more miscarriages had also had at least one pregnancy with a singleton birth that had reached 28 weeks gestation. Information was available on these 118 babies: 30% were small-for-gestational age (birthweight less than or equal to 10th centile using figures from Scotland 1973-79), 28% were born preterm, and the perinatal mortality rate (excluding babies of less than 28 weeks gestation) was 161/1000 births, all of which are significantly increased above the prevalence for a normal obstetric population. These observations may serve to alert the clinician to the increased risk of these complications when dealing with women who have a history of recurrent miscarriage.
