Efficacy of pulsed estrogen therapy in relatively younger patients with surgically induced menopause.

BACKGROUND: Pulsed estrogen therapy is a new approach in estrogen replacement therapy. We carried out a prospective study to evaluate the efficacy of pulsed estrogen therapy in relatively younger patients with surgically induced menopause. METHODS: Patients (n=138) <45 years old and suffering from severe vasomotor symptoms secondary to surgically induced menopause were included in the study. After the initiation of pulsed estrogen therapy (300 microg/day), the patients were re-evaluated every 4 weeks. The dose was increased at each follow-up, if necessary (to a maximum of 600 microg/day). The patients who preferred another method after the first 12 weeks were prescribed oral conjugated estrogen (0.625 mg/day) and at the end of the second 12 weeks their satisfaction levels were assessed. RESULTS: At the end of the first 12 weeks, 26 patients were completely satisfied (18.8%) and 47 were moderately satisfied (34.1%), whereas 65 concluded that the pulsed estrogen therapy they received was ineffective (47.1%). At the end of the second 12 weeks, all the patients were completely satisfied. CONCLUSION: Pulsed estrogen therapy for 12 weeks reduced the frequency of hot flushes in relatively younger patients with surgically induced menopause; however, 81.2% of patients were not completely satisfied at the end of this period.

Evaluation of bone turnover in postmenopausal patients with type 2 diabetes mellitus using biochemical markers and bone mineral density measurements.

Although osteoporosis is reported as a potential complication of type 1 diabetes mellitus (DM), the effects of type 2 DM on bone mass are conflicting. Most of the studies conducted in recent years reveal that bone mineral density (BMD) values of type 2 DM patients are not decreased and even increased when compared with healthy control groups. In this study we evaluated bone turnover in 57 postmenopausal type 2 DM patients utilizing biochemical markers for bone formation and resorption, and BMD measurements. We found that BMD values in diabetic patients (0.91 +/- 0.11 g/cm(2) for lumbar region, 0.89 +/- 0.14 g/cm(2) for hip region) were higher than healthy postmenopausal control group (0.81 +/- 0.12 g/cm(2) for lumbar region, 0.76 +/- 0.10 g/cm(2) for hip region). Serum alkaline phosphatase values were similar to the control group, whereas serum osteocalcin and N-telopeptide/creatinine (NTx/Cr) values were significantly lower than the control group (osteocalcin: 8.82 +/- 4.03 ng/ml, NTx/Cr: 122.70 +/- 81.76 nMBCE/mMCr) in diabetic patients (osteocalcin: 4.44 +/- 3.53 ng/ml, NTx/Cr: 42.24 +/- 29.97 nMBCE/mMCr). Also a significant correlation was observed between body mass index and BMD values. Our findings suggested that the bone turnover rate is remarkably lower in type 2 DM patients compared to healthy postmenopausal patients.

Risk factors and infant outcomes associated with umbilical cord prolapse.

OBJECTIVES: Our goal was to identify risk factors associated with umbilical cord prolapse and to review the perinatal outcome of cases of cord prolapse. METHODS: During the study years 77 cases were identified retrospectively. Associations between cord prolapse and potential risk factors were evaluated by means of the odds ratio. RESULTS: Of the 77 fetuses with umbilical cord prolapse 9.1% had a fetal weight of < 2500 gas compared with 9.4% for fetuses in control group (P > 0.05). The umbilical cord prolapse occurred in association with vertex presentation 66 times (85.7%), breech presentation nine times (11.7%) and transverse presentation two times (2.6%). The occurrence of breech presentation among the control cases was 2.6%, and that of transverse lie was 1.7% (P < 0.01). Case mothers were 1.6 times more likely to be multiparas compared with the control group (P < 0.01). The perinatal mortality rate was 39/1000. CONCLUSIONS: Our study showed that abnormal fetal presentation and multiparity are associated with an increased risk of umbilical cord prolapse. The association of risk of cord prolapse with low birth weight was statistically insignificant (P > 0.05). We suggest that the cesarean delivery decreased the risk of perinatal mortality among cases of cord prolapse.

Inevitable hysterectomy despite conservative surgical management in advanced cervical pregnancy: a case report.

A 35-year-old woman was diagnosed to have cervical pregnancy of 10.2 weeks duration. Methotrexate therapy was not chosen due to the presence of active tuberculosis. Since the patient had gradually increasing vaginal hemorrhage, she was taken to the operating room. A dilatation and curettage could not control the hemorrhage. A laparotomy was performed and the uterine arteries were ligated. A cervical hysterotomy was also performed to evacuate the products of conception. There was active bleeding in the cervix although no products of conception were observed. Two purse string sutures were placed, but the persistence of profuse bleeding despite these measures necessitated total hysterectomy.

Reasons why women have induced abortions in a developing country.

OBJECTIVE: The immediate explanation that women often give for seeking induced abortion is that the pregnancy was unplanned or unwanted. However, the myriad social, economic and health circumstances that underlie such explanations have not yet been fully explored. We wanted to evaluate these factors that lead one to have an abortion. STUDY DESIGN: This prospective study was performed on 588 women applied to our family planning unit to obtain an abortion. Analysis is based on the records of the women's age, educational level, their contraceptive usage and the reasons that they give for having an abortion. We also examined how these reasons were related to women's age, educational attainment and contraceptive choices. RESULTS: The desire to postpone a birth or to stop childbearing is a very common reason given by the women seeking abortion. It is seen that despite the women's desire to postpone or stop childbearing, the majority of them were not using an effective contraceptive method. Women's age is closely related to their reasons for seeking an abortion. On the other hand, we have found no clear association between women's educational level and their main reasons for seeking an abortion. CONCLUSION: Reasons women give for why they seek abortion are often far more complex than simply not intending to become pregnant. While improved contraceptive use can help reduce the unintended pregnancy and abortion, some abortions will remain difficult to prevent, because of limits to women's ability to determine and control all circumstances of their lives.

Acardiac twinning where the pump twin dies in utero due to thrombosis in the umbilical arteries.

A case of acardiac twinning where the pump twin dies in utero due to massive thrombotic occlusion of umbilical arteries at a site of umbilical cord stricture of the intact twin. In acardiac twinning the morbidity and mortality of the pump twin can be reduced by some invasive or medical approaches. The authors believe that in this interesting case the death of the pump twin could not be prevented by antenatal treatment.

Outcome of 1040 consecutive breech deliveries: clinical experience of a maternity hospital in Turkey.

OBJECTIVE: To determine the optimal route of delivery in breech presentation. METHOD: One-thousand and forty singleton breech deliveries among a total of 41785 deliveries that occurred at Zubeyde Hanim Maternity Hospital between 1990 and 1994 were analyzed. RESULT: The breech deliveries accounted for 2.4% of all deliveries. Of the patients, 572 (56.3%) were delivered vaginally and 468 (43.7%) were delivered by cesarean section. The mean ages of vaginal and cesarean delivery groups were 25.2 and 24.6 years, respectively. Forty-one (3.9%) of the fetuses had congenital anomaly. The leading congenital anomalies were meningocele in seven and hydrocephalus in six patients. Mullerian anomalies were encountered in 29 (6.1%) patients at cesarean section. Fetal morbidity observed in cesarean deliveries were fracture of the humerus in one and fracture of the femur in one and soft tissue injury in four cases. Fracture of the humerus was observed in two, Erb's paralysis in four, facial paralysis in one and soft tissue injury in 43 fetuses delivered vaginally. The leading causes of puerperal maternal morbidity were genital tract lacerations in vaginal delivery group and wound infection in cesarean delivery group. The overall perinatal mortality of this series was 54.8/1000 (57/1040). The corrected figures for cesarean delivery and vaginal delivery groups were 8.5/1000 (4/467) and 57.9/1000 (32/552), respectively. CONCLUSION: We favor a selective approach for mode of delivery in patients with breech presentation in order to balance the fetal morbidity associated with vaginal delivery and maternal morbidity and cost associated with cesarean delivery.

Emergency postpartum hysterectomy.

Twenty-two deliveries were followed by emergency postpartum hysterectomy among 109,842 deliveries in the last 10 years, an incidence of 1 in 4992 deliveries (20/100,000). The leading causes of emergency postpartum hysterectomy were uterine rupture in 8 (36.3%), uterine atony in 7 (31.8%), and abnormally adherent placenta in 6 (27.3%) patients. Five of the uterine rupture cases followed previous cesarean births, whereas the other 3 followed dystocia. Of the 7 patients with uterine atony, 4 were after vaginal delivery and 3 were after cesarean birth. Of the 6 patients with adherent placenta, 4 had repeat cesarean deliveries and the other 2 were subjected to cesarean section for postterm pregnancies. The maternal mortality rate was found to be 4.5% (1/22). The perioperative morbidity included blood transfusion in 72.2%, febrile morbidity in 40.9%, and wound infection in 13.6% of the patients. Fetal mortality rate was 45.4%.

Maternal mortality in a maternity hospital in Turkey.

BACKGROUND: To determine the leading causes of maternal mortality in a large maternity hospital and to define priorities regarding this subject throughout Turkey. METHODS: Retrospective, institutional study among 100,531 live births between 1983 and 1992. RESULTS: Seventeen maternal deaths took place in this institution. Thus, the overall maternal mortality ratio was 16.9 per 100,000. The leading causes of maternal mortality were hemorrhage in seven (41.2%) and pulmonary embolism in six (35.3%) patients. The majority of deaths were observed in the 25-29 and 30-34 age groups and in patients with parity more than two. CONCLUSION: The relatively low figure of 16.9/100,000 for maternal mortality may be seen as a promising health index. However, obstetric hemorrhage is still the leading cause of this series. Pregnant women less than 20 years old and greater than 35 years old, and grand multiparous women as well as women with hypertension and heart disease are at high mortality risk. The observation of such cases demands further efforts for improved obstetric care in the hospital and throughout Turkey.

Primary twin ovarian pregnancy.

A 20-year-old-woman, gravida II, para I, was admitted to the hospital with vaginal bleeding 17 weeks after her last menstrual period. Her pelvic examination was found to be compatible with 3.5 months of pregnancy by the attending physician. Ultrasonographic examination revealed an empty uterus and two dead fetuses with biometric data consistent with 14 weeks of pregnancy located in the left ovarian region. She was subjected to an explorative laparotomy and an intact gestational sac including the left ovary with normal tubes was observed; a unilateral salpingo-oophorectomy was carried out. Histologic studies confirmed a twin ovarian pregnancy. Although rare, ovarian pregnancy should be considered when approaching a case of ectopic pregnancy. Early diagnosis is generally based on ultrasonographic findings. Advanced cases with unruptured sac and multiple gestations may also be present.
