Effects of induced menopause on Burch colposuspension for urinary stress incontinence.

The clinical and urodynamic short term results after colposuspension for urinary stress incontinence has been studied in a group of young patients in whom menopause was induced surgically and compared with a similarly treated group who did not undergo surgical castration. Clinically, no differences were found in the incidence of diurnal frequency, nocturia, urgency, urge incontinence or stress incontinence between the groups. No urodynamic changes in the cystometric, uroflowmetry and urethral pressure profile measurements were found post-operatively between the two groups. It is concluded that surgically induced menopause in the absence of aging has no effect on the results of colposuspension for urinary stress incontinence in the short term.

Obstetric outcome in women with congenital uterine malformations.

Ninety-eight cases of congenital uterine malformations were diagnosed with hysterosalpingography (HSG). Symmetric uterine malformations, composed of bicornuate uterus, uterus didelphys and septate uterus, constituted 80% of the cases. Of them, 75% were of the bicornuate type. Infertility (55%) and a suggestion of cervical incompetence (24%) were the main indication for HSG. Premature deliveries (29%), spontaneous first-trimester abortions (24%), ectopic pregnancies (3%), abnormal fetal presentations (23%) and a high cesarean section rate (27.5%) occurred in those patients. The highest rate of first-trimester abortions (47%) and the lowest rate of term deliveries (21%) occurred in the group with T-shaped uteri as compared to a 7% rate of early abortions (P less than .05) and 61% rate of term deliveries (P less than .03) in the unicornuate uterus group. In 30% of the patients with uterine malformations, cervical incompetence was diagnosed. Improved obstetric outcomes occurred in patients treated with cervical cerclage. There was a statistically significant difference between the number of premature deliveries and spontaneous late abortions in the group without cerclage (50%) and that with cerclage (21%) (P less than .001).

Clear ovarian cyst aspiration guided by vaginal ultrasonography.

Thirty patients with clear ovarian cysts underwent aspiration guided by vaginal ultrasound. In 23 cases a complete aspiration was accomplished. In 4 only partial aspiration was possible, and in the remaining 3 failed aspiration led to surgery. Histological findings correspond to retroperitoneal lipoma and mucinous cystadenoma (2 cases). Malignant cells were not detected in the fluid of any of the 27 aspirates. Eight of the ten patients presenting with abdominal pain experienced a relief following aspiration. Recurrence of the cyst occurred in 12 cases (40%) with significantly smaller dimensions (P less than 0.01). Vaginal ultrasound aspiration of clear cyst is easy and safe and can be considered as an outpatient procedure.

Nonsurgical management of tubal pregnancy. Necessity in view of the changing clinical appearance.

The incidence of ectopic pregnancy is definitely increasing. Ectopic pregnancies are diagnosed earlier these days because of the improvement in diagnostic means and the increasing awareness of the condition. It seems that there is a dramatic change in the clinical presentation of this disease; it used to be a grave and life-threatening condition, and now it is a more benign presentation. The vast majority of the diagnosed ectopic pregnancies are unruptured. This has stimulated various investigators to attempt nonsurgical methods of treatment such as systemic administration of methotrexate or RU 486 (mifepristone) or local injection of methotrexate, potassium chloride, or prostaglandins under laparoscopic or ultrasonographic guidance. Most of these conservative, nonsurgical measures proved efficient in 80% to 90% of cases. Expectant management, which was practiced in some cases, proved to be equally successful. We believe that the ideal mode of treatment in early unruptured ectopic pregnancy is still to be determined. The answer probably lies in proper selection.

Fertility before and after surgery for primary ovarian pregnancy.

Primary ovarian pregnancy usually occurs in parous fertile women. It is an accidental event probably related to the presence of the IUD affecting implantation rather than an indicator of altered fertility. Reproductive performance postoperatively remains unmodified.

Delayed fertilization and poor embryonic development associated with impaired semen quality.

Delayed fertilization is common in cycles with immature oocytes. This phenomenon was observed in 42 of 423 with mature oocytes. Of the 42 cycles, 16 were excluded because of the presence of sperm autoantibodies. Sperm parameters of the remaining 26 (6.1%) cycles (group A) were compared with those in cycles with no fertilization at all (group B) and those in the control group (group C). The percentage of normal forms was 15% in group B and 24% in group A compared with 51% in group C. Fertilization rates were 32% in group A compared with 81% in group C. The incidence of poor embryonic morphology was 82% in group A compared with 29% in group C. Delayed fertilization and poor embryonic morphology associated with impaired sperm quality is of clinical and prognostic importance.

The absence and effect of induced menopause by gonadotropin-releasing hormone analogs on lower urinary tract symptoms and urodynamic parameters.

The clinical and urodynamic relationship between the onset of menopause and the appearance of lower urinary tract symptoms has been studied in 12 premenopausal urinary symptom-free patients in whom hypoestrogenism was induced by treatment with gonadotropin-releasing hormone analogs. No urodynamic changes in the cystometric, uroflowmetry, and urethral pressure profile measurements were found after 6 months of treatment. Clinically, only one patient had diurnal frequency after treatment. We conclude that estrogen deficiency in the absence of aging and other factors leading to urinary symptoms is probably of minimal significance as a cause of lower urinary tract disability in the immediate menopausal period.

Mifepristone (RU486) alone or in combination with a prostaglandin analogue for termination of early pregnancy: a review.

The availability of a medical mode of termination of early pregnancy by the administration of RU486, an antiprogesterone alone, or in combination with one of the PG analogues significantly reduces the maternal morbidity and mortality associated with the classical surgical abortion. RU486 given alone in early pregnancy induces complete abortion in 60% to 85% of cases, and when combined with prostaglandin analogues, gemeprost or sulprostone, reaches a success rate of 95% to 99%. RU486 may also be of potential value in the medical treatment of ectopic pregnancy. Its use as a postcoital contraception is suggested, but further research is required to determine whether RU486 can be used on a once-a-month basis for contraception.

The effect of prostaglandins and aspirin--an inhibitor of prostaglandin synthesis--on adhesion formation in rats.

The effect of intraperitoneal application of prostaglandins E2 and F2 alpha and of aspirin, a non-steroidal anti-inflammatory drug, on the formation of intraperitoneal adhesions was investigated in rats, in view of the main role of the body's reaction in adhesion formation. Intraperitoneal adhesions were induced by inflicting uniform trauma to the uterine serosa. It was demonstrated that prostaglandin E2 may increase adhesion formation and that intraperitoneal aspirin is able to inhibit its formation.

The dilemma of the optimal surgical procedure in ectopic pregnancies occurring in in-vitro fertilization.

Ectopic pregnancy remains one of the undesired sequelae of in-vitro fertilization (IVF) treatment. It seems that mechanical infertility increases the risk of this complication in IVF. Thus, the surgeon treating such a case faces the dilemma of the optimal surgical procedure because of the increased risk for repeated ectopic pregnancy in subsequent IVF cycles. Two cases are presented with repeated ectopic pregnancy occurring in IVF. One case underwent salpingectomy on the first occasion and eventually developed a contralateral repeat ectopic gestation ending with salpingectomy. The second case underwent a conservative salpingotomy in the first event and developed a repeated ectopic gestation on the same side, undergoing bilateral salpingectomy. In order to prevent repeated ectopic pregnancies in an IVF programme, a definitive surgical procedure, such as bilateral salpingectomy, should be considered in the first episode in patients referred for IVF because of tubal pathology.

Gonadotropins and combined gonadotropin-releasing hormone agonist--gonadotropins protocols in a randomized prospective study.

A prospective study was designed to compare cycles stimulated by human menopausal gonadotropin (hMG) (group A) with cycles pretreated with gonadotropin-releasing hormone agonist causing pituitary desensitization followed by hMG stimulation (group B). Three hundred two cycles were randomly allocated to each group. Cancellation rate was 27.2% in group A compared with only 3.3% in group B. Significantly less hMG ampules for a shorter period were needed in group A patients. Lower estradiol and higher luteinizing hormone levels were detected in the hMG group. Patients in group B yielded significantly more oocytes and more embryos per retrieval. A significantly higher pregnancy rate per cycle was obtained in group B (27%) as compared with that of group A (13%). Moderate and severe ovarian hyperstimulation syndrome was significantly more frequent in group B than in group A.

Iatrogenic injuries to the ureter during gynecologic and obstetric operations.

Iatrogenic injuries to the ureter are hazardous complications of pelvic and vaginal operations, causing severe morbidity and even mortality. Eighteen such instances that occurred during the last 30 years are analyzed. Most of the injuries were associated with attempts to achieve hemostasis without proper identification of the ureter. The incidence of ureteral injuries declined during the years concomitantly with the improvement of surgical techniques. The proper identification and, when necessary, isolation of the ureter during operations in which there is a risk is crucial in reducing the incidence of ureteral injuries. Those diagnosed at the time of injury and treated with end to end anastomosis had the best results. Delayed diagnosis and treatment were associated with poor end results. The English literature is reviewed.

Outcome of continued pregnancies after first- and second-trimester cervical dilatation by laminaria tents.

In 21 pregnant women (seven in the first trimester and 14 in the second trimester), laminaria tents inserted for induction of elective abortion were removed after dilatation had been achieved, but upon the patient's request, the abortion was not carried out. Four patients again changed their minds and had uncomplicated induced abortion after reinsertion of the laminaria tents. Seventeen patients continued their pregnancies: Fourteen had term deliveries, two had premature deliveries, and one had a spontaneous abortion at 10 weeks' gestation, 2 weeks after laminaria removal. None of the patients suffered infectious morbidity, including three untreated patients with positive cervical cultures for chlamydia, who experienced normal pregnancies and deliveries.

The frequency of the delta F508 mutation on cystic fibrosis chromosomes in Israeli families: correlation to CF haplotypes in Jewish communities and Arabs.

We have analysed the distribution of the delta F508 mutation and the haplotypes of cystic fibrosis (CF) bearing chromosomes among the Israeli CF population. The population was classified according to its ethnic origin and included 3 groups, Ashkenazi Jews, Sephardic/Oriental Jews and Arabs. Haplotype B (KM19 allele 2, XV2c allele 1) was found to be the predominant haplotype in all groups but in each of them the haplotype distribution was different. The delta F508 mutation was present in all groups and accounts for 32% of the CF mutations. It was mainly associated with the B haplotype but only one third of the CF chromosomes with this haplotype carry the delta F508 mutation.
