Comparison between fluproquazone and indomethacin in treatment of primary dysmenorrhoea.

Two prostaglandin synthesis inhibitors, fluproquazone (100 mg) and indomethacin (25 mg), were compared in a double-blind, crossover study for treatment of primary dysmenorrhoea in 31 patients. Each drug was used during two consecutive menstruations in randomized order. Both treatments significantly relieved spasmodic pains and other dysmenorrhoeic symptoms. No significant differences were found between the treatments in regard to the overall efficacy assessed at the end of each treated cycle. However, 20 patients preferred indomethacin and 7 patients fluproquazone. Three patients reported mild side-effects with fluproquazone as compared to five patients wih indomethacin. It is concluded that both treatments can be used for treatment of primary dysmenorrhoea.

Comparison between naproxen tablets and suppositories in primary dysmenorrhea.

Naproxen tablets and suppositories were compared, in the treatment of primary dysmenorrhea, in a double-blind cross-over trial. The results on 32 patients treated during 128 menstruations with either tablets and suppositories were analysed. Both naproxen tablets and suppositories produced a significant but similar overall relief of dysmenorrhea, although the tablets had a better effect in relieving spasmodic pain than the suppositories (p < 0.05). Occasions of failure to obtain relief were not related to the occurrence of vomiting or diarrhea during the trial. Vomiting seems not to be responsible for the therapeutic failures of oral treatments with prostaglandin-synthetase inhibitors in primary dysmenorrhea.

Results in the operative treatment of pelvic endometriosis.

Two hundred and eight patients treated surgically for endometriosis were reviewed one to four years later. The incidence of endometriosis in this survey was 17 per cent of all gynecological laparotomies. After operation, 30 per cent of the patients were symptomless, 60 per cent estimated the alleviation as good or moderate, and only 10 per cent had no benefit from the operation. In the 32 cases where infertility was the main indication for operation and other factors affecting fertility were excluded, 20 pregnancies of 19 women were achieved after operation.

Serum ferritin in the evaluation of iron status in young healthy women.

The iron stores of 17 healthy young women were evaluated by a serum ferritin assay and by bone marrow iron determinations. Iron stores were absent or scanty in about 70% of subjects. A high degree of correlation was demonstrated between serum ferritin concentration and bone marrow iron stores. The mean serum ferritin level in women with absent iron stores was 26 microgram/l, compared with 114 microgram/l in women with sufficient bone marrow iron stores. Repeated measurements of serum ferritin, iron, transferrin and blood hemoglobin during the menstrual cycle revealed no significant changes in these parameters.

Serum ferritin as a measure of iron stores during and after normal pregnancy with and without iron supplements.

The iron stores of 32 healthy pregnant women were evaluated longitudinally during pregnancy and 6 months post partum by serum ferritin assay and by bone marrow iron content. Half of the women were receiving oral iron while the others were not given iron supplementation. Women receiving iron could maintain their iron stores throughout the pregnancy. By contrast, women without iron therapy had low serum ferritin values, pointing to the absence of iron stores during the last trimester, and 6 of these 16 women developed anemia. This was confirmed by estimation of the quantity of stainable iron in the bone marrow. In addition serum iron, transferrin and red cell MCV values indicated iron deficient erythropoesis. During a 6-month period after pregnancy the women receiving supplemental iron during pregnancy had a significant increase in their serum ferritin concentrations, indicating restoration of iron stores. Women not receiving iron during pregnancy had exhausted iron stores at term and serum ferritin values stayed low even at 6 months after delivery. If iron therapy was instituted after parturition, serum ferritin assays indicated restoration of iron stores within the ensuing 6 month. To prevent iron deficiency anemia during pregnancy supplemental iron is advisable for all pregnant women in our country.

Evaluation by serum ferritin assay of the influence of maternal iron stores on the iron status of newborns and infants.

Serum ferritin concentration was measured in 47 paired maternal and newborn (umbilical cord sample) blood specimens during delivery. The serum ferritin concentration was also measured in 31 of the above babies at the age of six months. Serum ferritin concentration of the newborn babies (mean 222 microgram/l) born to the mothers with a low serum ferritin content at term (mean 28 microgram/l) was significantly lower (p < 0.05) than that of those (mean 324 microgram/l) born to the mothers with a normal ferritin concentration (mean 102 microgram/l). The difference between the two groups of infants persisted for at least the whole study period of 6 months (mean at 6 months of age 99 microgram/l and 150 microgram/l, respectively).

Serum ferritin in the diagnosis of anemia during pregnancy.

Measurements of serum ferritin were correlated with bone marrow iron content and other laboratory hematological indices in 44 anemic (B-Hb < 110 g/l) pregnant women. Seventy-two % of patients classified as iron deficient by the absence of bone marrow iron had diagnostically low serum ferritin concentrations, which percentage is about double compared with those revealed by measurements of serum transferrin, TIBC, transferrin saturation, serum iron, blood hemoglobin and red cell indices. It is also important that serum ferritin was the only one of these measurements which was able to differentiate between iron deficiency, and anemia due to infection. Seven out of 8 patients with anemia due to infection had elevated serum ferritin levels. In 17% of patients no reason for the fall of blood hemoglobin could be shown. A plausible explanation for the low blood hemoglobin is extensive hemodilution.

Decreased intervillous and unchanged myometrial blood flow in supine recumbency.

The supine position in late pregnancy is associated with many hemodynamic changes caused by compression of the inferior vena cava and a resulting fall in cardiac output. To investigate the effect of this position on uteroplacental blood flow, 22 women with normal (N = 12) or hypertensive (N = 10) pregnancy were investigated using the intravenous 133Xe washout method, in both the supine and left-tilted (45-degree) lateral positions. The intervillous blood flow (113 +/- 48 ml/min/dl) was lower in the supine position than in the left-tilted position (141 +/- 48 ml/min/dl) (P less than 0.01), while the myometrial blood flow was similar in both (9.0 +/- 3.3 ml/min/100 g in supine and 8.7 +/- 2.7 ml/min/100 g in left-tilted position). The results suggest that the autoregulation system for uteroplacental circulation is operative only in the nonplacental component of the pregnant uterus.

The refief of primary dysmenorrhea by ketoprofen and indomethacin.

The prostaglandin biosynthesis inhibitors ketoprofen and indomethacin were compared in the treatment of primary dysmenorrhea in a double-blind, cross-over trial involving 23 patients. Each drug was used for 2-4 days during 3 consecutive menstruations in randomized order. Good or moderate overall relief was obtained in 60 of the 68 ketoprofen-treated menstruations (88%). A dysmenorrhea score, based on subjective estimations of 8 symptoms, similarly decreased from a mean (+/- S.E.M.) basal level of 9.6 +/- 0.6 to 3.6 +/- 0.3 during ketoprofen treatment and to 4.0 +/- 0.3 during indomethacin. Both drugs relieved pelvic and lower back pains and eliminated vomiting and diarrhea in 82-97% of the cycles whereas headache, fatigue and nervousness were less frequently alleviated (40-67%). Eighteen of the 23 women (78%) had been unable to work during the first day of menstruation, the rate of working days lost was reduced to 4% with ketoprofen and 9 with indomethacin. Mild side-effects occurred during 12 ketoprofen and 14 indomethacin therapies. Ketoprofen thus seems to be as effective and tolerable as indomethacin in the treatment of primary dysmenorrhea.

Prostaglandin biosynthesis inhibitors and endometriosis.

Prostaglandins (PGs) may be involved in the development of the symptoms of endometriosis. Therefore 18 patients with pelvic endometriosis were treated in placebo controlled double-blind trial with different prostaglandin biosynthesis inhibitors. These drugs were: acetylsalicylic acid (0.5 g x 3) exerting a weak PG-synthetase inhibition, indomethacin (25 mg x 3) inhibiting PG-synthetase, and as a representative of fenamates, tolfenamic acid (200 mg x 3), which both inhibits PG-synthetase and antagonizes PGs at the target level. The therapeutic effect was evaluated using a specific endometriosis score separately during menstruation and in premenstrum. Prostaglandin biosynthesis inhibitors did not alleviate premenstrual complaints better than placebo. During menstruation tolfenamic acid relieved endometriotic symptoms more effectively than placebo while indomethacin and acetylsalicylic acid did not differ from placebo. A drug which inhibit both the synthesis and action of PGs can thus be used in the alleviation of secondary dysmenorrhea due to endometriosis.

Serum gonadotrophins, prolactin and ovarian steroids in primary dysmenorrhoea.

Serum samples were collected from 27 women with incapacitating primary dysmenorrhoea and from 16 normal women in the early part of the cycle (between day 3 to 6), at midcycle (between days 13 to 16) and in the late part of the cycle (between days 23 to 26) for determination of FSH, LH, prolactin (PRL), 17 beta-oestradiol (E2) and progesterone (P). The gonadotrophin and P levels showed normal and similar ovulatory patterns in both groups. The PRL concentrations (mean +/- SD) in dysmenorrhoeic women were lower than normal in the early part (9.2 +/- 4.0 ng/ml vs 14.5 +/- 7.3 ng/ml, p less than 0.01) and in the late part of the cycle (11.7 +/- 5.2 ng/ml vs 16.5 +/- 10.2 ng/ml, p less than 0.05), but not so at midcycle (9.1 +/- 2.8 ng/ml vs 10.4 +/- 4.4 ng/ml, p greater than 0.05). The E2 level was higher than normal in dysmenorrhoeic women in the late cycle (163.0 +/- 76.7 pg/ml vs 93.3 +/- 64.3 PG/ML, p less than 0.01), but apart from this the ratio of E2/P did not differ between the groups. These hormonal changes may be related to an excessive production of endometrial prostaglandins in primary dysmenorrhoea.

Maternal and foetal plasma bupivacaine concentrations in labour with segmental epidural analgesia.

Maternal and foetal plasma bupivacaine concentrations were assayed following segmental epidural analgesia during the first stage of 14 normal labours. Analgesia was accomplished with 20 mg of 0.5% bupivacaine. 10 mothers received only one dose and four mothers two doses. The maternal and foetal plasma bupivacaine levels remained very low and the foetomaternal ratios were about 1:4 during the labour. At delivery, the foeto-maternal ratio increased, showing that the decline of bupivacaine concentrations is slower in foetal than in maternal plasma.
