Clinical, endocrine, and metabolic effects of acarbose, a alpha-glucosidase inhibitor, in overweight and nonoverweight patients with polycystic ovarian syndrome.

OBJECTIVE: To determine the clinical, endocrine, and metabolic effects of acarbose use in overweight and nonoverweight patients with polycystic ovarian syndrome (PCOS). DESIGN: Prospective analysis. SETTING: Gynecology and infertility clinic of a tertiary care medical center. PATIENT(S): Seventy-four patients with PCOS and 30 healthy women. INTERVENTION(S): Acarbose use. MAIN OUTCOME MEASURE(S): Clinical findings of hyperandrogenism, body mass indices, LH, FSH, DHEAS, total T, PRL, basal insulin, fasting glucose/insulin levels, and lipid profiles. RESULT(S): Acarbose treatment improved LH/FSH levels, decreased total T, DHEAS, basal insulin, low-density lipoprotein, very low-density lipoprotein, and triglyceride levels, and increased high-density lipoprotein levels in patients with PCOS. Basal insulin and fasting glucose/insulin levels reacted more significantly in overweight patients undergoing acarbose treatment. CONCLUSION(S): Acarbose has been found to improve insulin levels and thus glucose/insulin ratios more effectively in overweight patients compared with nonoverweight patients with PCOS. This drug seems to be an effective drug to be used in overweight as well as nonoverweight patients with PCOS.

Effects of epidural analgesia using ropivacaine on the mother and the newborn during labor.

OBJECTIVE: To evaluate the effects of epidural analgesia using 0.2% Ropivacaine on the mother, newborn and during labor. METHODS: This study was conducted at the Zeynep Kamil Obstetric, Gynecology, and Pediatric Research and Training Hospital in Istanbul, Turkey, between July 2003 and April 2004. Eighty pregnant women of 37-41 weeks' gestation were enrolled in the study. Forty cases received epidural analgesia (group 1) and the control group composed 40 cases (group 2). Duration of labor, systolic and diastolic blood pressures at initial, 15th, 30th, 45th and 60th minutes, and number of breathing per minute, pulse rates, fetal heart rates and presence of motor block were recorded. Blood gas assessments from the umbilical cord, 1st and 5th minute Apgar scores were noted following the delivery. Way of delivery, adverse effects and complications of the epidural analgesia were recorded. RESULTS: Mean age of the cases was 24.79 +/- 4.72 years. Duration between full cervical dilation and delivery (phase 2) was significantly longer in group 1 (p<0.01). Sixty minutes systolic arterial pressure was significantly lower in group 1 (p<0.05). In group 1, diastolic arterial pressures at 15th, 45th, 60th minutes (p<0.01) and 30th minute (p<0.05) were significantly lower when compared to the initial values. No significant differences were recorded in terms of breathing rates, umbilical cord CO2, O2, pH levels and Apgar scores between the 2 groups. The most common adverse effect of epidural analgesia was sedation (59%). The second dose of Ropivacaine was needed in 24 (61.5%) cases in group 1. In group 1, 29 (74.4%) patients expressed their pleasure as very good regarding the epidural analgesia. CONCLUSION: Epidural analgesia, if administered by a specialist to a properly selected patient at proper time, leads to a comfortable delivery by relieving the pain. It can be performed safely after taking an informed consent.

Efficacy of laparoscopically-assisted extracorporeal cystectomy in patients with ovarian endometrioma.

STUDY OBJECTIVE: To investigate the usefulness and effectiveness of the extracorporeal surgical technique in the treatment of endometriomas. DESIGN: Retrospective evaluation (Canadian Task Force Classification II-2). SETTING: Department of gynecology in a tertiary care faculty hospital and training hospital. PATIENTS: Of 89 patients with endometrioma, 53 had laparoscopic stripping, and 36 had laparoscopically-assisted extracorporeal cystectomy. INTERVENTIONS: Laparoscopic stripping and laparoscopically-assisted extracorporeal cystectomy were performed for the treatment of endometriomas diagnosed laparoscopically. MEASUREMENTS AND MAIN RESULTS: The size of the endometrioma diagnosed by the ultrasonographic examination was not statistically related to the severity of the endometriosis (p = .42). Conversion to extracorporeal technique was required in 17 of 58 cases with moderate endometriosis and 14 of 31 cases with severe endometriosis (p = .04). Operation time, visual analogue pain score, and hospitalization periods were similar between the 2 techniques. Among 53 specimens obtained with laparoscopic stripping, 29 (55%) had no ovarian tissue, and 24 (45%) had ovarian tissue with follicles. Of 36 specimens obtained with extracorporeal technique, 19 (52%) had no ovarian tissue, and 17 (48%) had ovarian tissue with follicles. Preservation of the ovarian tissue was not significantly different between both surgical techniques. CONCLUSIONS: Extracorporeal technique with laparoscopically-assisted minilaparotomy is a valuable alternative for laparoscopic stripping in selected cases.

The effects of oxidative stress on outcomes of assisted reproductive techniques.

PURPOSE: To investigate the impact of oxidative stress on pregnancy success by monitoring malondialdehyde levels in follicular fluid. METHODS: Forty five couples were enrolled in this prospective study. Following long protocol of GnRH analogues and r-FSH treatment, oocyte retrieval and intracytoplasmic sperm injection were performed. Malondialdehyde levels were assayed by thiobarbutiric acid reacting substances test. Student's t-test and chi(2) test were used for statistical analysis. RESULTS: Patients were divided into two groups; group I (pregnancy positive, n = 20), group II (pregnancy negative, n = 25). There was no statistical significant difference in terms of age, infertility period, FSH levels on the third day, number of oocytes retrieved and fertilization rates between the two groups. Pregnancy rates were found to be decreasing in higher malondialdehyde levels. CONCLUSION: Malondialdehyde can be used as a marker of oxidative stress and a potential marker in predicting assisted reproductive techniques outcome.

Ratio of middle cerebral to umbilical artery blood velocity in preeclamptic & hypertensive women in the prediction of poor perinatal outcome.

BACKGROUND & OBJECTIVES: Doppler velocimetry studies of placental and foetal circulation can provide important information regarding foetal well-being providing an opportunity to improve foetal outcome. The present study was undertaken to evaluate the role of middle cerebral to umbilical artery blood velocity waveform's systolic/diastolic ratio (MCA/UA) and biophysical profile as a predictor of perinatal outcome in hypertensive and preeclamptic pregnant women during the late third trimester. METHODS: Fifty preeclamptic pregnant women selected randomly in the last three weeks of the third trimester were stratified into two groups based on the MCA/UA ratio. All women were evaluated by foetal biophysical profile scoring. Thirty four women with foetal MCA/UA ratios > 1 and 16 with < or =1 were recruited in groups A and B respectively. The results of the ratio, and biophysical profile were evaluated with respect to the outcome of the infants and adverse perinatal outcome, defined as perinatal death, foetal cord blood gas analyses, cesarean delivery for foetal distress, admission to the neonatal intensive care unit, days in the neonatal intensive care unit (NICU) or low Apgar score. RESULTS: Rate of cesarean delivery was significantly (P<0.001) higher in group B than group A. There was a statistically significant increase in perinatal morbidity in B group. Apgar scores at 1 and 5 min were found to be lower in group B than group A. Umbilical cord blood partial oxygen pressure (pO2), partial carbon dioxide pressure (pCO2) was not different in the two groups; whereas, pH was lower in group B. In group A two neonates (5.9%) and in group B 12 neonates (75%) required admission in neonatal intensive care unit. Best cut-off levels of MCA, MCA/UA ratios were found to be 3 and 1, respectively. INTERPRETATION & CONCLUSION: The MCA/UA was valuable for predicting the outcome of preeclamptic and hypertensive pregnancies. When the ratio was <1, foetal prognosis was poor.
