The assessment of maternal and umbilical cord homocysteine levels in obese pregnant women.

PURPOSE: The aim of this study was to compare the maternal plasma and umbilical cord blood homocysteine levels in obese and non-obese pregnant women. MATERIALS AND METHODS: One hundred-ten term pregnant women, who completed their 3711, gestational weeks and were not in active labor, were enrolled in the study. While 41 out of them were obese (BMI ≥ 30 kg/m(2)), 69 were non-obese (BMI < 30 kg/m(2)). The maternal plasma and umbilical cord homocysteine levels and umbilical cord pH values were compared between the groups. The statistical analyses were performed using t-test, Mann Whitney test, and Chi-square test. Ap < 0.05 value was set as statistically significant. RESULTS: The mean of age was higher in obese group in borderline significance (26.8 ± 5.4 vs. 28.8 ± 5. l,p = 0.049). The mean of gestational weeks, birthweight, the mode of delivery, and umbilical cord pH values were similar between the groups (p > 0.05). The maternal plasma homocysteine levels [median (interquartile range); 7.6 (4.1) vs. 7.1 (4.9)] and umbilical cord homocysteine values were not statistically different [8.6 (4.2) vs. 8.8 (4.5)] between the groups (p > 0.05). CONCLUSION: The maternal and umbilical cord blood homocysteine levels are not different in obese and non-obese pregnant women.

Dynamic thiol-disulfide homeostasis in hyperemesis gravidarum.

OBJECTIVE: To determine serum thiol-disulfide homeostasis in hyperemesis gravidarum. STUDY DESIGN: Twenty-six pregnant women with hyperemesis gravidarum and 37 healthy pregnant women were included in the study. Native thiol, disulfide and total thiol concentrations were measured with a novel automated method. RESULTS: Serum disulfide levels were 15.68±4.41 µmol l(-1) in the hyperemesis gravidarum group and 13.49±2.81 µmol l(-1) in the healthy group (P=0.031). Native thiol levels were 213.86±26.29 µmol l(-1) in the hyperemesis gravidarum group and 232.18±19.21 µmol l(-1) in healthy group (P=0.004), and total thiol levels were 245.23±28.58 µmol l(-1) in the hyperemesis gravidarum group and 259.17±19.94 µmol l(-1) in the healthy group (P=0.038). CONCLUSION: Native and total thiol were deficient in the hyperemesis gravidarum group and this deficiency was correlated with the severity of the disease. The thiol-disulfide balance has shifted to the oxidative side. This metabolic disturbance may have a role in the pathogenesis of hyperemesis gravidarum.

Reduced total antioxidant status in postterm pregnancies.

BACKGROUND: The placenta is the major source of oxidative stress in normal human pregnancy. The placental tissue is typically functional in postterm pregnancies. We hypothesized that such pregnancies experience deteriorating oxidative balance and increasing oxidative stress. In this case-control study, our aim was to investigate the oxidative status in postterm pregnancies comparing with term by using total antioxidant status (TAS) measurement. METHODS: Fifty pregnant women who were in their 41st gestational week (GW) and whose labor had not yet started were selected for the study group. Fifty subjects whose spontaneous labor onset and who delivered before their 41st GW were included for control group. Venous blood samples were obtained from each participant before the onset of labor. A premixed reagent was used to obtain serum TAS measurements from the blood samples. The Mann-Whitney test was used to compare the groups. RESULTS: Age, gravity, and parity of the subjects were similar between the groups (p> 0.05). Body mass index (BMI) were statistically higher in postterm group (p =0.011). The median (interquartile range) TAS level was lower in the pregnancies beyond 41 weeks than term pregnancies [1.69 (0.12) mM vs 1.75 (0.20) mM, (p< 0.05)]. CONCLUSIONS: A lower total antioxidant status in past days pregnancy suggests an association with decreased oxidative status compared to term. It can be speculated that pregnancies beyond 41 weeks are associated with decreased oxidative stress and this may be play a role in the etiology of the prolonged pregnancy.

Increased frequency of MEFV gene mutations in patients with primary dysmenorrhea.

OBJECTIVES: Familial Mediterranean fever (FMF) is an autoinflammatory disease characterized by recurrent attacks of fever and polyserositis and an autosomal recessive inheritance mode. Up to 15 % of FMF patients are reported to experience perimenstrual attacks. Primary dysmenorrhea could be an incomplete abdominal attack, or patients with dysmenorrhea may have increased frequency of MEFV gene mutation carriage. Therefore, we aimed to evaluate the frequency of MEFV gene mutations in patients with dysmenorrhea. METHODS: Eighty-four patients with primary dysmenorrhea attending consecutively to our gynecology department and 73 healthy female controls selected from hospital staff were included in the study, and MEFV gene mutations were analyzed. RESULTS: The prevalence of total allelic variants was significantly increased in dysmenorrhea patients (p = 0.015); analysis of individual variant rates revealed a significant increase in the frequency of MEFV gene mutations in dysmenorrhea patients compared with the control group (p = 0.036). CONCLUSION: Gynecologists and primary care physicians must be aware of FMF in the differential diagnosis of dysmenorrhea.

Haemorrhoids during pregnancy.

Haemorrhoids are varicose veins of the rectum covered by mucosa at or near the anal canal. They are normally asymptomatic, can occur at any age and affect both males and females. In this review, we address the issue of the approach of the obstetrician to haemorrhoids and their management. Haemorrhoids are common in young women and commoner during pregnancy and the puerperium. Obstetricians and gynaecologists should be familiar with haemorrhoids, a proctological disease, diagnosis and their treatment, but they have little experience regarding the impact of pregnancy on haemorrhoids. The obstetrician must be able to relieve symptoms in patients who are pregnant, or who have just delivered.

Vaginitis in Turkish women: symptoms, epidemiologic - microbiologic association.

OBJECTIVE: To determine the relationship between clinical-epidemiologic findings and microbiologic results in vaginitis. METHODS: A prospective study of 212 women with vaginal symptoms was undertaken. Each patient underwent an evaluation that included standardized history, interview after pelvic examination and vaginal culture. RESULTS: Only 45% of patients received diagnosis. Only two symptoms were more frequently noted with diagnosis. Itching was more frequent in vulvovaginal candidiasis (VCC) whereas odor was more frequent in Bacterial vaginosis (BV). BV was associated with a history of spontaneous and induced abortion, increased number of pregnancy, vaginal douching practice and intrauterine contraceptive device usage. VVC was found to be associated with no contraceptive usage and previous vaginitis history. CONCLUSION: Presenting symptoms alone or with microbiologic studies has limited value, and that of the women with vaginal symptoms may lack a microbiologic diagnosis. Evidence-based approaches that produce highly accurate diagnostic and effective treatment regimens would be expected in the future.

Maternal serum levels of dehydroepiandrosterone sulfate and labor induction in postterm pregnancies.

OBJECTIVES: To study the relationship between maternal endogenous dehydroepiandrosterone sulfate (DHEAS) levels, success of labor induction, and Bishop scores in postterm pregnancies. METHODS: There were 65 postterm pregnancies. Group 1 consisted of women spontaneously in the active phase of labor, and group 2 of women with hypotonic uterine contractions whose labor was inducted by oxytocin. Levels of DHEAS were studied from venous blood samples. Demographic data and Bishop scores were recorded. RESULTS: The demographic characteristics of patients were similar, but DHEAS levels were higher in group 1 than in group 2 (P<0.001). Linear regression analysis showed a significant relationship between DHEAS and Bishop scores. DHEAS levels in women delivered vaginally were significantly higher than in women delivered by cesarean section. From the receiver operating characteristics (ROC) curve, DHEAS levels might determine the mode of delivery and success of labor induction; however, Bishop scores do not. CONCLUSIONS: DHEAS levels may be an important factor influencing the efficiency of labor and the success of labor induction in postterm pregnancies.

Pethidine versus tramadol for pain relief during labor.

OBJECTIVE: To evaluate and compare the analgesic efficacy and adverse effects of tramadol and pethidine in labor. METHOD: Fifty-nine full term parturients were randomly assigned to one of two groups in active labor. Group 1 received 100 mg pethidine; group 2, 100 mg tramadol, intramuscularly. Analgesic efficacy, maternal side effects, changes in the blood pressure, heart rate, and duration of labor were assessed. RESULT: At 30 and 60 min after drug administration, pain relief was greater in the pethidine group than in tramadol group. The incidence of nausea and fatigue was higher in the tramadol group. Following drug administration the decrease in systolic and diastolic blood pressure and the increase in heart rate were statistically significant in both groups. No significant difference was found between the groups when compared for duration of labor and Apgar scores. None of the neonates developed respiratory depression. CONCLUSION: Pethidine seems to be a better alternative than tramadol in obstetric analgesia because of its superiority in analgesic efficacy and low incidence of maternal side effects.

Effects of diphenhydramine HCl and methylprednisolone in the prevention of abdominal adhesions.

OBJECTIVE: The purpose of this study was to determine the effects of diphenhydramine hydrochloride and methylprednisolone in peritoneal adhesions. MATERIALS AND METHODS: Forty-eight male rats were used in the study. The rats were anesthetized by 5 mg/kg ketamine hydrochloride. After opening the abdomen, 10 longitudinal incisions of 2 to 3 cm in length were made on the right parietal peritoneum, and a 2 cm(2) peritoneal layer was excised from the left abdominal wall. The abdomen was closed with 3/0 silk suture. Group I was the control group, group II was given 10 mg/kg diphenhydramine intravenously, group III was given 20 mg/kg methylprednisolone intravenously, and group IV was administered both of the drugs in the above doses. A blood sample of 2 mL was taken from the rats on the 14th day after the operation. The animals were then sacrificed. The abdomen was opened and abdominal adhesions were examined. A tissue sample of 1 g was taken from the abdominal incision line. Albumin, zinc, and hemoglobin levels and leucocyte counts in the blood were determined as well as hydroxyproline levels in the tissue. RESULTS: Numbers of adhesions were as follows: 9 in group I, 3 in group II, and 2 in group III. No adhesion was observed in group IV. Albumin, zinc, and hemoglobin levels and leucocyte counts were found to be similar in all groups. Hydroxyproline levels in the tissue were significantly lower in groups III and IV than in groups I and II (P <0.05). CONCLUSIONS: Diphenhydramine and methylprednisolone reduced postoperative adhesions significantly in rats. Further investigations are needed in order to use these drugs as antiadhesive agents in humans.
