Reproductive outcomes following hysteroscopic resection of endometrial polyps of different location, number and size in patients with infertility.

We aimed to assess the pregnancy rates after hysteroscopic polypectomy in infertility patients with endometrial polyps and to compare pregnancy rates among subgroups with polyps of different location, size and number. All patients who underwent hysteroscopic evaluation which revealed endometrial polyps were included. Patients with any intrauterine pathology other than polyp and those undergoing frozen embryo transfer (ET) cycles were excluded. Patients were evaluated according to polyp location, size and number. Rates of ß-hCG positivity and clinical pregnancy were compared. Clinical pregnancy rates after polypectomy was 41.7% for multiple polyps, 30.8% for isthmus zone polyps, 28.6% for anterior wall polyps, 27.3% for cornual zone, 22.2% for posterior uterine wall polyps and 11.8% for fundal polyps (p = 0.532). There appears no difference regarding reproductive outcomes after hysteroscopic resection of polyps situated in different intrauterine locations. Similarly, chance of conceiving seems not to change after hysteroscopic treatment of polyps of different size and number.

Intrinsic factors rather than vitamin D deficiency are related to insulin resistance in lean women with polycystic ovary syndrome.

OBJECTIVE: To investigate the correlation between insulin resistance (IR) and serum 25-OH-Vit D concentrations and hormonal parameters in lean women with polycystic ovary syndrome (PCOS). PATIENTS AND METHODS: 50 lean women with PCOS and 40 body mass index (BMI) matched controls were compared in terms of fasting insulin and glucose, homeostatic model assessment insulin resistance (HOMA-IR), 25-OH-Vit D, high sensitivity C-reactive protein (hs-CRP), luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone, dehydroepiandrosterone sulfate (DHEA-S), total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides and Ferriman-Gallway (FG) scores. Correlation analyses were performed between HOMA-IR and metabolic and endocrine parameters. RESULTS: 30% of patients with PCOS demonstrated IR. Levels of 25-OH-Vit D, hsCRP, cholesterol, HDL, LDL, triglyceride and fasting glucose did not differ between the study and control groups. Fasting insulin, HOMA-IR, LH, total testosterone, and DHEA-S levels were higher in PCOS group. HOMA-IR was found to correlate with hs-CRP and total testosterone but not with 25-OH-Vit D levels in lean patients with PCOS. CONCLUSIONS: An association between 25-OH-Vit D levels and IR is not evident in lean women with PCOS. hs-CRP levels do not indicate to an increased risk of cardiovascular disease in this population of patients. Because a strong association between hyperinsulinemia and hyperandrogenism exists in lean women with PCOS, it is advisable for this population of patients to be screened for metabolic disturbances, especially in whom chronic anovulation and hyperandrogenism are observed together.

Hysterectomy with preservation of both ovaries does not result in premature ovarian failure.

This study investigated ovarian function and adnexial pathology following total abdominal hysterectomy with preservation of both ovaries compared with that in a control group. Data from 29 patients who had undergone total abdominal hysterectomy at age < or =40 years and 42 menopausal patients with no previous ovarian pathology were evaluated retrospectively. The mean (+/- SD) age of menopause was 49.7 +/- 1.5 years in the total abdominal hysterectomy group and 50.1 +/- 1.3 years in the control group; this difference was not statistically significant. The incidences of cyst and hydrosalpinx were 31% and 6.9%, respectively, in the total abdominal hysterectomy group and 44.8% and 0%, respectively, in the control group. The increased incidence of cysts in the total abdominal hysterectomy group was statistically significant. In conclusion, patients who undergo total abdominal hysterectomy without oophorectomy do not experience premature menopause. Preservation of the ovaries may avoid the disadvantages of hormone replacement therapy at the expense of a higher risk of developing adnexial pathology.

Reliability of second trimester triple screening for Down syndrome in rhesus-negative women.

OBJECTIVE: To find out whether there is considerable influence on second trimester serum concentrations owing to the rhesus status. STUDY DESIGN: This retrospective cohort study was performed at the Perinatology Unit of the GATA Haydarpasa Teaching Hospital. During the study interval, 2265 pregnancies met inclusion criteria. The blood samples were collected in 117 pregnancies with a maternal rhesus-negative blood group status. The control group consisted of 2148 pregnancies with a maternal rhesus-positive blood group status. Statistical analysis was performed by SPSS 11.0 statistical software. RESULTS: Pregnancies with a maternal rhesus-negative blood group status were identified in 117 patients. The overall prevalence of pregnancies with a maternal rhesus-negative blood group status were 5.1% in our study. Only unconjugated estriol multiples of the median values were significantly decreased in rhesus-negative women (P<0.001). Alpha-fetoprotein and human chorionic gonadotrophin multiples of the median values did not differ significantly (P>0.05). CONCLUSION: We conclude that if second trimester screening test to be used in Rh negative pregnancies, either the corrected value should be referred or double test result should be considered ignoring the unconjugated estriol result. Another option is the first trimester Down syndrome screening test.

Combination of hypoosmotic swelling/eosin Y test for sperm membrane integrity evaluation: correlations with other sperm parameters to predict ICSI cycles.

The objective of our study was to evaluate the accuracy of the combination of hypoosmotic swelling (HOS) and eosin Y (Ey) exclusion tests to predict the ICSI cycles' outcome and its correlations with other sperm parameters. The functional and structural integrity of sperm membrane was evaluated with the combined HOS/Ey test in 95 ICSI cycles and the results were correlated with other sperm parameters, including concentration, motility, strict morphology, and total motile sperm count. The combined HOS/Ey test was evaluated for the prediction of the ICSI cycles' outcome parameters including fertilization, cleavage, and pregnancy rates. The HOS/Ey test presented significant relationships with concentration, motility, and strict morphology (p < 0,0001) but it couldn't predict the fertilization, cleavage, and pregnancy outcomes of ICSI cycles. The combined HOS/Ey test has strong correlations with motility and strict morphology parameters of sperm samples but is not sufficiently sensitive to estimate the outcome of ICSI cycles.

P-wave dispersion is increased in pregnancy due to shortening of minimum duration of P: does this have clinical significance?

Most pregnant women complain of palpitation, and various kinds of arrhythmias can be observed during pregnancy. We investigated P-wave and QT dispersion during pregnancy. Healthy pregnant women (n=162) and healthy age-matched, non-pregnant women (n=150) were included. We performed electrocardiography and transthoracic echocardiography and determined serum oestradiol levels in both groups, and performed Holter monitoring in the pregnant group only. Resting heart rate, P-wave dispersion, left ventricular diastolic diameter, left atrial diameter and serum oestradiol levels in the pregnant group were significantly higher than in the control group. Minimum P-wave duration was shorter in the control group than in the pregnant group; however, there was no statistically significant difference in maximum P wavelength and corrected QT dispersion between the groups. No atrial fibrillation was detected in the pregnant group during Holter monitoring. Shortening of the minimum P-wave duration leads to increased P-wave dispersion during pregnancy. In contrast to other pathologies with increased P-wave dispersion, paroxysmal atrial fibrillation is absent in pregnant women; this may be a result of the stable maximum P wavelength that is present during pregnancy.

Comparison of letrozole and clomiphene citrate in women with polycystic ovaries undergoing ovarian stimulation.

Letrozole was compared with clomiphene citrate (CC) as a first-line treatment for ovulation induction in women with polycystic ovaries (PCOs). A total of 106 women with primary infertility and a diagnosis of PCOs were randomized to receive either 100 mg CC (n = 55) or 2.5 mg letrozole (n = 51) daily for 5 days. Human chorionic gonadotrophin (hCG) at a dose of 10000 IU was administered when at least one follicle with a mean diameter > or = 18 mm was observed using transvaginal ultrasound. The number of mature follicles was significantly lower, but endometrial thickness and ovulation and pregnancy rates were significantly higher in the letrozole group than in the CC group. In conclusion, letrozole is associated with a higher pregnancy rate than CC in PCO patients and may have a role as a first-line treatment for anovulatory patients with PCOs.
