Gynecologic and obstetric investigation

The sonographic and histologic findings observed in 11 cases of ovarian fibrothecoma were compared, and an attempt was made to find a correlation between each histologic type of the tumor (pure thecoma, predominantly fibrous fibrothecoma, mixed fibrothecoma) and its sonographic appearance. The presence of a homogeneous echogenic pattern, with marked posterior acoustic shadowing, in the absence of any calcification, was highly suggestive of a predominantly fibrous ovarian fibrothecoma; the presence of a diffusely hypoechoic ovarian mass, with no posterior echo enhancement, was strikingly correlated with pure thecomas; mixed fibrothecomas were characterized by the presence of an echogenic pattern with no posterior acoustic shadowing. Sonographic findings, even though nonspecific, can provide the clinician with useful information which permits to detect these rare neoplasms preoperatively.

Effect of oxytocics on prostaglandin levels in the third stage of labour.
The levels of prostaglandin F2 alpha metabolites (PGFM) in the peripheral blood were measured during third stage in a group of patients not given any oxytocic and this was compared with the levels produced in other groups given different oxytocics. There was a significant rise in PGFM within 5 min of delivery in all groups but there was no statistical difference in the serum concentrations of PGFM between the different groups. This suggests that oxytocics given during third stage do not act through release of prostaglandins.

Randomized Controlled Trial Clinical TrialPrevention of a side effect of epidural morphine by epidural steroid administration in cesarean section.
In order to evaluate the effect of preventive corticosteroid on the occurrence of pruritus after epidural anesthesia with morphine, we studied 95 patients undergoing cesarean section. Thirty-seven patients (group I) were given 20 mg of bupivacaine 0.5% for the operation and 2 mg of morphine hydrochloride with 50 mg of Ultracortene-H immediately after the operation and 24 h later, and 58 patients (group II) were given epidural bupivacaine during the operation and epidural morphine hydrochloride immediately after the operation and 24 h later without Ultracortene-H. Only 8.1% of group I patients had pruritus after the injection compared to 20.6% in group II. We suggest that the addition of 50 mg Ultracortene-H to 2 mg epidural morphine analgesia after the operation might prevent severe forms of pruritus.

Acupuncture before delivery: effect on pain perception and the need for analgesics.
Pain experience and the amount of analgesics needed during labor were studied in 32 primiparous women who had received repeated treatment with acupuncture (AP) during the month prior to term and in 16 nontreated primiparous women. The women's psychological profiles were evaluated by a psychiatric interview at week 38 of pregnancy. Treatment with AP did not reduce the need for analgesics in labor. ⋯ Experience of pain was not reduced in subjective assessments in women treated with AP. There was a strong correlation between assessments of pain made during labor and 6 months after delivery. In the group that did not receive AP, cerebrospinal fluid dynorphin A was significantly lower in parturients who chose epidural anesthesia.

Efficiency of transvaginal scanning in obstetric and gynecologic fields.
Transvaginal ultrasonography was done on 26 pregnant women ranging from 5 to 27 weeks of gestation and 12 patients with gynecologic diseases. In early gestation, significant correlations were found among gestational age, crown-rump length, diameter of yolk sac and fetal heart rate. ⋯ Fine structures and individual organs were better evidenced transvaginally. Therefore, transvaginal ultrasound affords pertinent information complementary to that obtained with the transabdominal technique.
