Closed mitral valvotomy in pregnancy--a Malaysian experience.

Our experience from 1968 to 1985 in 12 women requiring closed mitral valvotomy during pregnancy is reviewed. All patients had severe mitral stenosis and were in functional class 3 (2 patients) or class 4 (10 patients). Mitral valvotomy was performed between the 18th and the 30th week of pregnancy using a transventricular dilator. Improvement in functional class was noted in all patients postoperatively. One patient had postvalvotomy mitral regurgitation and heart failure, which responded to diuretics; the subsequent course was uneventful. Eleven patients had normal deliveries; whilst one patient had a Caesarean section for an obstetric indication. All babies were normal and there was no maternal death. This series confirms that closed mitral valvotomy can be performed with an acceptable degree of safety during pregnancy, when indicated.

Intestinal obstruction following previous myomectomy and the use of beta-sympathomimetics in pregnancy.

Two cases of intestinal obstruction in pregnancy following previous myomectomy are reported. The use of tocolytic agents to suppress premature uterine contractions may be a predisposing factor and probably intensifies the obstruction. As the symptoms mimic the normal side-effects of pregnancy, the diagnosis is often delayed. Laparotomy was done, as initial conservative treatment was unsuccessful in both instances. A live baby was delivered in the first case, whilst the second case ended in an abortion.

Illegal abortion: an attempt to assess its cost to the health services and its incidence in the community.

This article describes a study designed to test a method for assessing the cost to the health services of illegally induced abortion and the feasibility of estimating the incidence of induced abortion by a field interviewing approach. The participating centers included three hospitals in Ankara, Turkey; three hospitals in Ibadan, Nigeria; one hospital in Caracas and one in Valencia, Venezuela; and two hospitals in Kuala Lumpur, Malaysia. Hospitalized abortion cases were classified as induced or spontaneous or as "probably induced," "possibly induced," or "unknown" according to a classification scheme comprising certain medical criteria. The sociodemographic characteristics of induced and spontaneous abortion cases were subjected to discriminant function analysis and the discriminating variables best characterizing the induced versus the spontaneous abortion groups were identified for each center. On the basis of this analysis, the "probably" and "possibly" induced and "unknown" categories were further classified as induced or spontaneous abortion, with stated probabilities. Thus an overall estimate is made of the proportion of all hospitalized abortions that can be considered illegally induced outside the hospital. Selected results on costs of induced and spontaneous abortion are shown. The method further tested the feasibility of obtaining valid survey data on abortion from the communities studied by re-interviewing the women hospitalized for induced and spontaneous abortion six months later in their homes. This exercise showed a degree of under-reporting of abortion that varied widely among centers, even among women who had admitted illegal induction at the time of hospitalization. The feasibility of estimating the incidence of illegal abortion by field studies is discussed in the light of these findings.

A multicenter randomized comparative investigation of ML Cu250, TCu-220C and Cu7 IUDs.

The final analysis of 1725 interval insertions of the 3 IUDs is presented. The earlier observations were confirmed at: at 24 months, no significant differences were found between the TCu-220C and ML Cu250 IUDs though the TCu-220C had a lower gross pregnancy rate (2.0 versus 2.9) and the ML Cu250 had a lower expulsion rate (2.3 versus 4.1). Expulsions were more common with the Cu7 when compared to the ML Cu250 (p 0.001) and T-220C (p 0.01); pregnancy rates were also higher with p values of 0.05 and 0.01 respectively. Other use-related terminations were not significantly different among the 3 IUDs and continuation rates at 24 months were: Cu7, 69, TCu-220C, 73, and ML Cu250, 74.

A randomised comparative evaluation of the copper 7, multiload copper 250 and T copper-22OC IUDs.

Two new Cu-IUDs, the TCu-22OC and Multiload Cu250, were evaluated against the Cu7 in 1,199 subjects in a randomised, multicentric trial using a common study protocol. During the 2 years following insertion, cumulative first-segment rates for total use-related terminations showed no significant differences between the 3 devices; however, the Cu7 had a significantly higher termination rate for accidental pregnancy compared to the TCu-22OC and its expulsion rate was significantly higher than the ML Cu250. The rate of accidental pregnancy was higher and the expulsion rate lower with the ML Cu250 compared to the TCu-22OC but these differences were not significant. The results are discussed in relation to IUD design and their application in family planning.

A study of menstrual patterns following laparoscopic sterilization with silastic rings.

The menstrual patterns of 281 women undergoing laparoscopic sterilization with silastic rings were studied prospectively. A significant increase in dysmenorrhea and irregular periods was seen soon after sterilization but this was transient, returning to presterilization levels by 12 months. Menorrhagia was not observed and the amount of menstrual blood loss showed a trend towards normal following sterilization. No permanent adverse effects on menstrual patterns were seen in the 1st year after sterilization. It is suggested that factors other than the sterilization procedure may be responsible for the high prevalence of menstrual dysfunction that has been reported following sterilization.
