Body Mass Index and Age at Natural Menopause

A population of 1.076 women aged between 40 and 54 years has been studied using the method of cluster-stratified and random sampling. The median age at menopause was 46.24 +/- 0.13 (mean +/- SEM) years. Obese women reach menopause on an average of 1.7 years earlier than women with chronic energy deficiency (p < 0.01). Other potential correlative measures, education, marital status, number of children, and urban/rural residence were found to have an effect on the age at menopause.

A retrospective analysis of adolescent pregnancies

Pregnancy in adolescence has been and continues to be a problem in public health. A retrospective study of 562 mothers, 18 years of age and below, was carried out. This study has shown a high incidence of preeclampsia (9.9%), low birth weight infants (17.2%), and preterm delivery (9.3%). It is imperative to institute a medical and educational survive with comprehensive prenatal care for adolescent mothers in order to improve the outcome of their pregnancies.

Maternal outcome in HELLP syndrome requiring intensive care management in a Turkish hospital

CONTEXT AND OBJECTIVE Despite the development of tertiary care facilities, intensive care and advanced blood banking techniques, pregnancy-related hypertensive disorders are the main cause of maternal mortality in most countries. Our purpose was to determine maternal outcome in pregnancies complicated by HELLP syndrome (hemolysis, elevated liver enzymes and low platelet count) that required intensive care management. DESIGN AND SETTING Retrospective study at Department of Obstetrics and Gynecology, and Department of Anesthesiology and Reanimation, Karadeniz Technical University, Trabzon, Turkey. METHODS 37 patients with HELLP syndrome admitted to the obstetric intensive care unit were analyzed retrospectively from 1992 to 2004. RESULTS All patients were hypertensive, with mean Glasgow coma score (GCS) of 11 +/- 3.96. Mean gestational age at delivery was 32 +/- 4.09 weeks. Delivery was vaginally in nine and by cesarean section in 27 patients. General anesthesia was used in 12 and spinal anesthesia in 25 patients. Maternal morbidity included acute renal failure (11%), disseminated intravascular coagulation (5%), acute lung edema (3%), severe ascites (11%), pleural effusion (3%), adult respiratory distress syndrome (11%), abruptio placenta (11%), cerebral edema (8%) and cerebral hemorrhage (40%). All patients required transfusions using blood products. There were 11 maternal deaths (30%). CONCLUSION Because of high maternal mortality and morbidity found among patients with HELLP syndrome, standard antenatal follow-up protocols should be applied, so as to obtain early diagnosis and improve the speed of transfer to obstetric departments with expertise in this field.

Coagulation inhibitors in preeclamptic pregnant women.

ObjectiveOur objective was to detect clinical evaluation of coagulation inhibitors in preeclamptic and normotensive pregnant women and to determine their important role in pathogenesis of preeclampsia.MethodsA total of 20 mild, 20 severe preeclamptic and 45 normotensive pregnant women were included in this study. The plasma value of antithrombin III (AT-III) activity, proteins C and S activity, PT, PTT, fibrinogen and platelet counts were determined.ResultsThe values AT-III were lower in women with severe preeclampsia than in controls (p<0.05). In all groups, there was no significantly difference in the concentration of protein C activity, protein S and fibrinogen (p>0.05). The plasma thrombocyte counts were significantly lower in severe preeclamptic women than in normotensive women (p<0.05). There was no significant difference in the prothrombin time value in all groups, but a significantly difference with regard to partial thromboplastin time between severe preeclamptic and the control group (p<0.0001). It was longer than the control.ConclusionThe markers of hemostasis activation such as protein S, protein C activity together with fibrinogen levels are not useful tools but the reduction of AT-III and platelet counts would seem useful in different pathological situations in pregnancy to predict and monitor the severity of the condition.

Comparison between HELLP syndrome, chronic hypertension, and superimposed preeclampsia on chronic hypertension without HELLP syndrome

Abstract Aim: To compare perinatal outcome of patients with HELLP syndrome to that of patients with chronic hypertension and superimposed preeclampsia on chronic hypertension without HELLP syndrome. Methods: We retrospectively evaluated the perinatal outcome of 147 pregnancies complicated by the HELLP syndrome, chronic hypertension, and superimposed preeclampsia on chronic hypertension without HELLP syndrome. Results: Gestational age at delivery and birthweights were lower among women with HELLP syndrome than among women with superimposed preeclampsia and chronic hypertension (P < 0.05). There were no statistically significant differences among the three groups with respect to intrauterine growth retardation, respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, Apgar score, admission to neonatal intensive care unit, overall rate of cesarean delivery and cesarean delivery rate for fetal distress. The total perinatal mortality rate was 17% (28/147) and was more frequent in the HELLP group (27%). Multivariate logistic regression analysis showed that gestational age at delivery (RR 0.45) and birthweight (RR 0.99) were risk factors for adverse outcome. Conclusions: Perinatal outcome is primarily influenced by gestational age at delivery and birthweight independent of the severity of the hypertensive status of pregnant women.

Methotrexate and misoprostol used alone or in combination for early abortion

The purpose of this study was to compare the outcome and side effects of using the drugs methotrexate and misoprostol, alone or in combination, to induce abortion. A total of 108 subjects who had requested elective termination of pregnancy and medical abortion at 9 weeks gestation or less were randomized into three groups. The first group received 50 mg/m2 intramuscular (i.m.) methotrexate on day 1 and, if the hCG level had risen by > 50% of the initial level on day 4, a second dose was given. They were then followed-up at weekly intervals up to day 21. Group 2 received 800 micrograms vaginal misoprostol on day 1 and, if ultrasound showed a gestational sac on day 4, they received a repeat dose and were re-examined on day 7. Group 3 received 50 mg/m2 methotrexate intramuscularly followed 3 days later by 800 micrograms vaginal misoprostol and were re-examined on day 7. Complete abortion occurred in 25 (69%) of the 36 subjects in group 1, 21 (58%) of the 36 subjects in group 2, and 32 (89%) of the 36 subjects in group 3. The complete abortion rate in group 3 was significantly higher than that of both group 1 and group 2 (p < 0.05). The incomplete abortion rate was significantly higher in group 2 as compared with both of the other groups (p < 0.05). There were significant differences between the mean gestational age of the successful abortions and the failures in group 1 (no abortion occurred at more than 49 days gestation), but not in groups 2 or 3. Vaginal bleeding in subjects who successfully aborted began within 16 +/- 4 days in group 1 after the first dose, and within 24 h in 18 (86%) of the 21 subjects in group 2 and 27 (84%) of the 32 subjects in group 3 after the misoprostol dose. The drugs caused no serious or prolonged side effects. The combination of methotrexate and misoprostol is a more effective abortifacient regimen than when either drug is used alone.

Effect of different preparations of hormone therapy on sexual dysfunction in naturally postmenopausal women.

Objective To compare the effect of different formulations of continuous combined hormone therapy on sexual performance in naturally postmenopausal women. Material and methods A total of 158 postmenopausal women were enrolled and prospectively randomized to the single-blind study. Fifty-four women received tibolone 2.5 mg, 53 received 2 mg estradiol and 2 mg dienogest (E2/dienogest), and 51 did not receive any menopausal therapy. The patients were monitored after 6 months. Attitudes of sexuality were evaluated by using the Rosens female sexual function index. Results Compared with E2/dienogest and the control group, tibolone treatment was associated with more improvement of sexual performance, including sexual desire, sexual arousal and satisfaction. Both of the hormone therapies decreased frequencies of vaginal dryness and painful intercourse. Conclusions Tibolone has more positive effects on the sexual dysfunction of postmenopausal women and may be an alternative to the E2/dienogest preparation in postmenopausal women with sexual dysfunction.

Acute Alterations in Biochemistry, Morphology and Contractility of Rat Isolated Urinary Bladder via Increased Intra-Abdominal Pressure

Objective: To determine the acute effects of increased intra-abdominal pressure (IAP) on the biochemistry, morphology and contractility of the rat isolated urinary bladder using an experimental laparoscopy model. Methods: We divided 24 adult female Sprague–Dawley rats into three groups. The control group (group I) was not subjected to increased IAP. In groups II and III, IAPs of 10 and 20 mm Hg, respectively, were established by carbon dioxide pneumoperitoneum for 60 min. Thirty minutes after desufflation, the rat urinary bladder dome was removed for in vitro pharmacological investigation, measurement of malondialdehyde (MDA) levels and histopathological examination. Statistical comparisons between groups were performed. Results: Tissue MDA levels in groups II and III were significantly higher than in the control group. In group II, only the lamina propria was significantly damaged. However, the epithelium, lamina propria, and serosa were significantly damaged in group III. Acetylcholine potentiated contractions in both IAP groups. Increased responses to electrical field stimulation in the IAP groups were significant only in group II. Conclusions: In this experimental model, 10 and 20 mm Hg of IAP induced by pneumoperitoneum increased MDA levels and caused important changes in the morphology and contractile response of the urinary bladder.

Objective:  To compare the cerebral magnetic resonance (MR) and electroencephalogram (EEG) findings in pre‐eclamptic and eclamptic pregnant women.

Thoracopagus Conjoined Twins: A Case Report

Objective. Conjoined twin is a rarely seen congenital anomaly together with severe mortality and morbidity. The more common types of conjoined twins include the thoracopagus type, where the fusion is anterior, at the chest, and involves the heart. We are reporting one case of conjoined thoracopagus twins diagnosed by ultrasonography at 11 weeks. Case Report. In a multigravid pregnant woman who has been admitted to our clinic with a diagnosis of conjoined twins, thoracopagus, by ultrasonography at an 11-week gestation, termination of the pregnancy was performed. Conclusion. Making an early diagnosis with ultrasonographic examination gives the parents a chance to elect pregnancy termination.
