Intravenous albumin for the prevention of severe ovarian hyperstimulation syndrome in an in vitro fertilization program: a prospective, randomized, placebo-controlled study.

OBJECTIVE: To evaluate the efficacy of i.v. administration of human albumin solution for the prevention of severe ovarian hyperstimulation syndrome (OHSS). DESIGN: A prospective, randomized, placebo-controlled study comparing the effects of i.v. administration of human albumin solution versus sodium chloride 0.9% solution at the time of oocyte retrieval with patients undergoing IVF-ET who are at high risk for the development of severe OHSS. SETTING: Specialized assisted reproduction unit. PATIENTS: Thirty-one patients undergoing IVF-ET who had serum E2 levels of 1,906 pg/mL (> 7,000 pmol/L) and multiple follicular development on the day of hCG administration. INTERVENTIONS: After hCG administration, patients were randomized to receive i.v., either 50 g of human albumin diluted in 500 mL of sodium chloride 0.9% or 500 mL of sodium chloride 0.9% at the time of oocyte retrieval. MAIN OUTCOME MEASURES: Ovarian size as measured by pelvic ultrasonography, development of ascites, serum E2 concentrations during the luteal phase, and results of the IVF-ET cycles. RESULTS: Although no patient who had received human albumin solution developed severe OHSS, there were four such cases in the control group. All four were hospitalized with marked ascites and ovarian enlargement. There were no significant differences between the two groups comparing serum E2 levels on the day of hCG administration and during the luteal phase, the number of oocytes retrieved, fertilization, and pregnancy rates. CONCLUSIONS: Our preliminary results suggest that the administration of human albumin solution may help to prevent the development of severe OHSS in high-risk patients. Further research is needed to assess the potential of this novel approach.

Diffuse Lewy body disease with immediate post-partum onset.

A previously healthy 27 years-old woman developed psychotic depression and parkinsonism shortly after delivery of her first child. Her neuropsychiatric symptoms progressed to dementia and she died 5 years after onset. Diffuse Lewy body disease was found at autopsy. This case is unusual because of the early age of onset and the abrupt development of symptoms following pregnancy.

Vaginal delivery of breech-vertex twins.

The safety of vaginal birth for breech-vertex twins has not been addressed directly before. We retrospectively compared the perinatal outcome of two groups of breech-vertex twins: 24 delivered vaginally and 35 delivered abdominally. Vaginal delivery was allowed under the same protocol developed for singletons in breech presentation. Both groups had similar maternal and neonatal characteristics except for a significantly higher rate (P = .003) of pregnancies after infertility in the abdominal delivery group. Intergroup differences in perinatal outcome, as measured by Apgar scores and morbidity and mortality cases, were not significant. Our data suggest that if measures for safe vaginal delivery are taken, this route appears to incur no morbidity and mortality for breech-vertex twins.

Aspiration of ectopic pregnancy under guidance of vaginal ultrasonography.

This case report describes the treatment of tubal pregnancy by aspiration of the gestational sac content and injection of methotrexate by transvaginal sonographic guidance. The confirmation of the embryo aspiration as indicated by disappearance of the embryo with its heart beat and the resulting 46,XY karyotype, raises the question whether methotrexate injection is necessary.

Endometrial morphology and hormonal profiles in in vitro fertilization patients.

Endometrial biopsy was performed in 27 infertile women participating in the IVF program. Their mean age was 31.8 years, 33% of the women being over 35 years old. The average duration of infertility was 6.9 years. The superovulation protocol consisted of hMG/hCG in 5 cases, of combined GnRH analog/gonadotropin therapy in 20 women, and 2 patients received combined contraceptive pill/gonadotropin treatment. Judging by hormonal profiles, follicular growth rate and number of oocytes retrieved, the response to stimulation was normal. The mean estradiol (E2) levels increased from 132.7 pg/ml on day -5 (SEM = 9.67) to 1272 pg/ml (SEM = 103.7) on the day of hCG administration and to 1813 pg/ml (SEM = 209.6) 1 day later. One day before the hCG application, the mean progesterone and LH levels were 1.34 ng/ml and 8.38 IU/ml, respectively. Only one patient had clinical hyperstimulation syndrome. Ova were harvested in all women, the mean number of oocytes being 7.7 (SEM = 0.83) per patient. In all 27 cases lack of fertilization or faulty ovum cleavage were observed. Thus, an endometrial biopsy (EB) was performed 72 h after oocytes retrieval. The mean estrogen and progesterone levels on the EB day were 610.9 pg/ml (SEM = 78.44) and 45.4 ng/ml (SEM = 7.53), respectively. Histologic examination of the endometrium showed normal secretory endometrium consistent with day 16-17 of spontaneous ovulatory cycle. Two women who received combined contraceptive pills/gonadotropin therapy showed inactive endometrium with subnuclear vacuoles and decidual reaction in the stroma similar to that observed in women on estrogen-progestin birth control medication.(ABSTRACT TRUNCATED AT 250 WORDS)

Perinatal outcome of twin pregnancies complicated with preeclampsia.

Twenty-five mild and 19 severe preeclampsia cases in twin pregnancies (12.5%) were compared to 44 matched for gestational age controls. All three groups were similar with respect to maternal age, intertwin birthweight differences, and rates of abdominal deliveries and low (less than 7) 5-minute Apgar scores. The frequency of primiparas in the severe preeclampsia group was significantly higher compared with controls (p less than 0.03). Severe preeclampsia patients delivered at a significantly earlier gestational age (p less than 0.005) and had a significantly lower mean twin birthweight (p less than 0.003) compared with the mild preeclamptic group. The mean twin birthweight of the severe preeclamptic cases was also significantly lower compared with that of controls. All three neonatal deaths occurred in severely discordant second twins born to severe preeclamptic patients. It is concluded that adverse perinatal outcome is associated with severe but not with mild preeclampsia in twin gestations.

Diffuse Lewy body disease and progressive dementia in a young woman.

This report details the emergence of a progressive parkinsonian syndrome, dementia and behavioural disturbance in a 33 year-old woman which can be dated to the delivery of her first child. The findings of this case indicate that cortical Lewy body disease should be considered in any patient with temporoparietal dementia and idiopathic Parkinson's disease irrespective of the age of onset.

The importance of the endopelvic fascia repair during vaginal hysterectomy.

During 1985 to 1989, 177 vaginal hysterectomies were performed in the Department of Gynecology, Kaplan Hospital, Rehovot, Israel, using the Porges technique with some modifications. Ninety patients had some degree of loss of the pelvic support--anterior or posterior wall relaxation, enterocele or uterine prolapse in various degrees. The patients were allocated to two groups, in which two different techniques were compared: group 1, with repair of the pubocervical and pararectal fascia and group 2 without the repair. The repair of the pubocervical and pararectal fascia after vaginal hysterectomy prevented vaginal vault prolapse (zero versus 15 percent, p < 0.01) and reduced the incidence of recurrent rectocele (23 versus 55 percent, p < 0.05) and recurrent cystocele (14 versus 45 percent, p < 0.005). Recurrent genuine stress incontinence was found in 9 percent of patients in group 1 and 18 percent of patients in group 2 (not statistically significant; p = 0.163). Optimal management of relaxation of the vaginal wall during vaginal hysterectomy requires clinical suspicion and precise preoperative diagnosis and therapeutic plan. In the present study, the need for careful repair of the pubocervical and pararectal fascia during vaginal hysterectomy to prevent vaginal vault prolapse is emphasized. This procedure does not prolong the operation significantly (92 +/- 15 versus 84 +/- 17 minutes) and has no deleterious postoperative complications.

[Ultrasonically-guided aspiration of clear pelvic cysts].

In 33 women aged 13-80, clear pelvic cysts were aspirated. The diameter of the cysts was between 4-11 cm and the aspiration, by either the vaginal or abdominal routes, was ultrasonically guided. In 25 cases (76%) there was no recurrence of a cyst during continuing follow-up. In 8 cases in which a cyst recurred, 4 were operated on and benign tumors were found. Ultrasonically guided aspiration is appropriate treatment for clear pelvic cysts.
