Spindle and chromosome configurations of in vitro-matured oocytes from polycystic ovary syndrome and ovulatory infertile women: a pilot study

To evaluate the meiotic spindle and chromosomal distribution of in vitro-matured oocytes from infertile nonobese women with PCOS and male or tubal causes of infertility (controls), and to compare in vitro maturation (IVM) rates between groups. Seventy four patients (26 with PCOS and 48 controls) undergoing stimulated cycles of oocyte retrieval for ICSI were selected prospectively. Thirteen PCOS patients and 27 controls had immature oocytes retrieved submitted to IVM. After IVM, oocytes showing extrusion of the first polar body were fixed and processed for evaluation of the meiotic spindle and chromosome distribution by immunofluorescence microscopy. There were no differences between PCOS and control groups with respect to IVM rates (50.0% and 42.9%, respectively) nor the percentage of meiotic abnormalities in metaphase II oocytes (35.3% and 25%, respectively). In vitro-matured oocytes obtained from stimulated cycles of nonobese PCOS did not have an increased ratio of meiotic abnormalities.

Thiele massage as a therapeutic option for women with chronic pelvic pain caused by tenderness of pelvic floor muscles

Aims and objectives Musculoskeletal system has been found to be involved in genesis and perpetuation of chronic pelvic pain (CPP) and has strong evidences that up to 80% of women with CPP present dysfunction of the musculoskeletal system. In this study, we report a series of women with CPP caused by tenderness of pelvic floor muscles successfully treated with Thiele massage. Methods Were included in this study six women with CPP caused by tenderness of the levator ani muscle that underwent transvaginal massage using the Thiele technique, over a period of 5 minutes repeated once a week for 4 weeks. After 1 month, the women returned for follow-up. Results The median tenderness score for the six women evaluated was 3 at the first evaluation and 0 after 1 month of follow-up (P < 0.01). The mean Visual Analogue Scale and McGill Pain Index scores were 8.1 and 34, respectively, at the first evaluation, and 1.5 and 16.6 at follow-up (P < 0.01). Conclusion Thiele massage appears to be very helpful for women with CPP caused by tenderness of the levator ani muscle. However, these results are preliminary and a larger number of women are necessary to obtain more conclusive results.

Increased basal FSH levels as predictors of low-quality follicles in infertile women with endometriosis

Objective: To determine whether basal levels of follicle-stimulating hormone (FSH) and anti-mullerian hormone (AMH), antral follicle count (AFC), and the numbers of dominant follicles, oocytes, and mature oocytes retrieved after ovarian stimulation differed between infertile women with endometriosis and healthy women undergoing assisted reproduction techniques (ART). Method: Of 77 consecutive ART candidates, 27 were infertile and had endometriosis. A male factor caused the infertility of the other 50, who acted as controls. Results: The AMH and AFC levels were similar in the 2 groups. The FSH levels were higher (8.28 mIU/ML [range, 5.25-24.1 mIU/ML] vs 5.91 mIU/mL [range, 2.47-18.7 mIU/ML]; P<0.01) in the study group. And the numbers of retrieved (n = 5 [range, 0-12] vs n = 9 [range, 0-27]; P<0.05) and mature oocytes (n = 4 [range, 0-11] vs n = 5 [range, 0-16]; P<0.05) were less in the study group. Conclusion: Because AMH levels were unchanged, endometriosis seems not to damage the primordial pool of follicles and oocytes, but to lessen the quality of the ovarian response to the hCG injection. Basal FSH levels may be of value in predicting ART success in women with the disease. (C) 2010 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

Basal levels of DNA damage detected by micronuclei and comet assays in untreated breast cancer patients and healthy women

Breast cancer is the second most frequent type of cancer worldwide and is the most common malignant disease among women. Risk factors for breast cancer include early menarche, late menopause, hormonal therapies, exposure to environmental pollutants, smoking and alcohol use. However, increased or prolonged exposure to estrogen is the most important risk factor. It has been suggested that accumulation of DNA damage may contribute to breast carcinogenesis. Epidemiological studies suggest that cytogenetic biomarkers such as micronuclei in peripheral blood lymphocytes may predict cancer risk because they indicate genomic instability in target tissues. The objective of the present study was to evaluate the frequencies of micronuclei and the extent of DNA damage detected by comet assay in peripheral blood lymphocytes of untreated breast cancer patients and healthy women. The study was conducted using peripheral blood lymphocytes from 45 women diagnosed for Ductal ""in situ"" or invasive breast carcinoma and 85 healthy control women. Micronuclei and comet assays were performed to detect spontaneous DNA damage. The results showed that micronuclei frequencies and tail intensity, detected by comet assay, were significantly higher in the breast cancer group than in controls. The levels of DNA damage were similar in smokers and non-smokers, and aging did not influence the frequencies of micronuclei or tail intensity values observed in either group. In conclusion, the present work demonstrates higher levels of DNA damage in untreated breast cancer patients than in healthy women.

Effect of low-dose combined oral contraceptive on aerobic capacity and anaerobic threshold level in active and sedentary young women

Background: The purpose of this study was to evaluate the effect of long-term use of oral contraceptives (DC) containing 0.20 mg of ethinylestradiol (EE) combined with 0.15 mg of gestodene (GEST) on the peak aerobic capacity and at the anaerobic threshold (AT) level in active and sedentary young women. Study Design: Eighty-eight women (23 +/- 2.1 years old) were divided into four groups active-OC (G1), active-NOC (G2), sedentary-OC (G3) and sedentary-NOC (G4) and were submitted to a continuous ergospirometric incremental test on a cycloergometer with 20 to 25 W min(-1) increments. Data were analyzed by two-way ANOVA with Tukey post hoc test. Level of significance was set at 5%. Results: The OC use effect for the variables relative and absolute oxygen uptake VO(2) mL kg(-1) min(-1); VO(2), L min(-1), respectively), carbon dioxide output (VCO(2), L min(-1)), ventilation (VE, L min(-1)), heart rate (HR, bpm), respiratory exchange ratio (RER) and power output (W) data, as well as the interaction between OC use and exercise effect on the peak of test and at the AT level did not differ significantly between the active groups (G1 and G2) and the sedentary groups (G3 and G4). As to the exercise effect, for all variables studied, it was noted that the active groups presented higher values for the variables VO(2), VCO(2), VE and power output (p<.05) than the sedentary groups. The RER and HR were similar (p>.05) at the peak and at the AT level between G1 vs. G3 and G2 vs. G4. Conclusions: Long-term use of OC containing EE 0.20 mg plus GEST 0.15 mg does not affect aerobic capacity at the peak and at the AT level of exercise tests. (C) 2010 Elsevier Inc.

Importance of Pelvic Muscle Tenderness Evaluation in Women with Chronic Pelvic Pain

Objective. To determine the prevalence of pelvic muscle tenderness in women with chronic pelvic pain (CPP) and to assess the importance of evaluating muscle tenderness in such women. Design. Observational study of 48 healthy female volunteers and 108 women with CPP, who were clinically evaluated for pelvic muscle tenderness by two researchers blinded to all clinical data. Results. The frequency of clinically detected pelvic muscle tenderness was significantly higher in women with CPP than in healthy volunteers (58.3% vs 4.2%, P < 0.001). Among women with CPP, those with pelvic muscle tenderness had higher Beck Depression Index scores (22 [6-42] vs 13 [3-39], P = 0.02) and higher rates of dyspareunia (63.5% [40/63] vs 28.9% [13/45], P < 0.004) and constipation (46.0% [29/63] vs 26.7% [12/45], P = 0.05) than those without pelvic muscle tenderness. Conclusion. Tenderness of pelvic muscles was highly prevalent among women with CPP and was associated with higher BDI scores and higher rates of dyspareunia and constipation. Determination of pelvic muscle tenderness may help in identifying women who require more intense treatment for CPP.

Variations of Jitter and Shimmer Among Women in Menacme and Postmenopausal Women

The objective of the study was to analyze comparatively the jitter and shimmer values of spoken voice among women in menacme and menopausal women using or not hormonal replacement therapy (HRT). Forty-five women were studied, divided into the following groups: Control Group (CG), 15 women aged 20-40 years with regular menstrual cycles who did not take hormonal contraceptives, Treated Group (TG), 15 women aged 45-60 years with at least 2 years of menopause, under continuous HRT with I mg estradiol valerate + 90 mu g norgestimate per day for at least 6 months; Untreated Group (UG), 15 women aged 45-60 years with at least 2 years of menopause who did not use HRT. Mean age was 30.3, 54.5, and 56.5 years for CG, TG, and UG, respectively. All subjects were submitted to acoustic analysis of jitter and shimmer for the sustained vowels /e/ and /i/. Mean jitter values were 0.56%, 0.64%, and 0.56% for the vowel /e/ and 0.88%, 0.79%, and 0.68% for the vowel /i/ for CG, TG, and UG, respectively. Mean shimmer values were 4.17%, 4.38%, and 4.77% for the vowel /e/ and 5.19%, 4.59%, and 5.37% for the vowel /i/ for CG, TG, and UG, respectively. There were no significant differences between the groups studied. The results obtained here by the methodology used suggest that there were no significant differences in jitter and shimmer when we assessed the sustained vowels /i/ and /e/ between menopausal women using or not HRT or between young and menopausal women treated or not.

Increased arterial stiffness in nonobese women with polycystic ovary syndrome (PCOS) without comorbidities: one more characteristic inherent to the syndrome?

Background Polycystic ovary syndrome (PCOS) is associated with adverse metabolic effects. Some cardiovascular disease (CVD) risk markers are increased in women with PCOS. However, early markers of atherosclerosis are also associated with obesity and insulin resistance, which are related to PCOS. These markers may result either directly from PCOS or indirectly as a consequence of the comorbidities associated with the syndrome. Context To assess the presence of early CVD markers in young, nonobese women with PCOS. Patients Forty women with PCOS and 50 healthy women with regular menstrual cycles, matched for age and body mass index (BMI). Measurements The following CVD markers were assessed by ultrasonography: common carotid artery (CCA) stiffness index (beta), distensibility and intima-media thickness (IMT), and brachial artery flow-mediated dilatation (FMD). Inflammatory markers, including interleukin (IL)-6, tumour necrosis factor (TNF)-alpha, homocysteine, C-reactive protein (CRP), glycaemia, lipid profile and insulin, were also assessed. Results CCA beta was higher in PCOS than in control women (3 center dot 72 +/- 0 center dot 96 vs. 3 center dot 36 +/- 0 center dot 96, P = 0 center dot 04) and CCA distensibility was lower (0 center dot 31 +/- 0 center dot 08 vs. 0 center dot 35 +/- 0 center dot 09 mmHg(-1), P = 0 center dot 02). Waist circumference, total testosterone and the Free Androgen Index (FAI) were higher in PCOS patients than in controls (78 center dot 2 +/- 10 center dot 0 vs. 71 center dot 5 +/- 7 center dot 2 cm, P = 0 center dot 001; 88 center dot 1 +/- 32 center dot 4 vs. 57 center dot 1 +/- 21 center dot 2 ng/dl, P < 0 center dot 01; 12 center dot 7 +/- 15 center dot 7%vs. 4 center dot 7 +/- 2 center dot 3%, P < 0 center dot 01, respectively), while SHBG was reduced (37 center dot 9 +/- 19 center dot 1 vs. 47 center dot 8 +/- 18 center dot 3 nmol/l, P = 0 center dot 01). The remaining variables did not differ between the groups. Conclusions Young women with PCOS exhibit changes in vascular elasticity even in the absence of classical risk factors for CVD, such as hypertension and obesity.

Distribution of fentanyl in the placental intervillous space and in the different maternal and fetal compartments in term pregnant women

Fentanyl is used in obstetrical practice to promote analgesia and anesthesia during labor and in cesarean delivery, with rapid and short-term effects. To determine fentanyl concentrations in maternal plasma, in the placental intervillous space, and in the umbilical artery and vein in term pregnant women. Ten healthy pregnant women underwent epidural anesthesia with fentanyl plus bupivacaine and lidocaine, and fentanyl concentrations were determined in the various maternal and fetal compartments, including the placental intervillous space, which has not been previously studied in the literature. The ratios of fentanyl concentrations in the various maternal and fetal compartments revealed an 86% rate of placental fentanyl transfer. The highest fentanyl concentrations were detected in the placental intervillous space, being 2.19 times higher than in maternal plasma, 2.8 times higher than in the umbilical vein and 3.6 times higher than in the umbilical artery, with no significant differences between the umbilical vein and artery, demonstrating that there was no drug uptake by fetal tissues nor metabolism of the drug by the fetus despite the high rates of placental transfer. The present study demonstrated that the placental intervillous space acted as a site of fentanyl deposit, a fact that may be explained by two hypotheses: (1) the blood collected from the placental intervillous space is arterial and, according to some investigators, the arterial plasma concentrations of the drugs administered to patients undergoing epidural anesthesia are higher than the venous concentrations, and (2) a possible role of P-glycoprotein (P-gp).

Glycodelin expression in the endometrium of healthy women and in the eutopic and ectopic endometrium of women with endometriosis

Objective: To analyze the expression of the glycodelin gene to better understand the molecular environment of endometriotic lesions and to elucidate the potential mechanisms that underlie the complex physiopathology of endometriosis. Design: Prospective laboratory study. Setting: University hospital. Patient(s): Eleven healthy fertile women and 17 patients with endometriosis in the early proliferative phase of the menstrual cycle. Intervention(s): Endometrial biopsy specimens were obtained from the endometrium of healthy women without endometriosis (controls) and from eutopic and ectopic endometrium tissues (pelvic and ovarian endometriotic implants) of endometriosis patients. Main Outcome Measure(s): The glycodelin relative expression level by real-time polymerase chain reaction (PCR) analysis. Result(s): The glycodelin down-regulation found in the endometriotic lesions was 332.26 and 123.17-fold lower, respectively, when compared with the eutopic tissue and the control endometrium. Conclusion(s): Glycodelin may be one of the molecules that contributes to the loss of cellular homeostasis in endometriotic lesions. (Fertil Steril (R) 2009;91:1676-80.

High levels of anxiety and depression have a negative effect on quality of life of women with chronic pelvic pain

Chronic pelvic pain (CPP) is a common and complex disease whose cause is often clinically inexplicable, with consequent difficulty in diagnosis and treatment. Patients with CPP have high levels of anxiety and depression, with a consequent impairment of their quality of life. The objective of this study was to determine the prevalence of anxiety and depression and their impact on the quality of life of women with CPP. A cross-sectional controlled study was conducted on 52 patients with CPP and 54 women without pain. Depression and anxiety were evaluated by the Hospital Anxiety and Depression Scale, and quality of life was evaluated by the World Health Organization Quality of life Whoqol-bref questionnaire. Data were analysed statistically by the Mann-Whitney U-test, the Fisher exact test, chi-square test and Spearman correlation test. The prevalence of anxiety was 73% and 37% in the CPP and control groups, respectively, and the prevalence of depression was 40% and 30% respectively. Significant differences between groups were observed in the physical, psychological and social domains. Patients with higher anxiety and depression scores present lower quality of life scores. The fact that DPC is a syndromic complex, many patients enter a chronic cycle of search for improvement of medical symptoms. The constant presence of pain may be responsible for affective changes in dynamics, family, social and sexual. Initially the person is facing the loss of a healthy body and active, to a state of dependence and limitations. In this study, patients with higher scores of anxiety and depression scores had lower quality of life and patients with lower scores of anxiety and depression had scores of quality of life. These results show that perhaps the depression and anxiety may be related to the negative impact on quality of life of these patients. In view of this association, we emphasise the importance of a specific approach to the treatment of anxiety and depression together with clinical treatment to improve the quality of life of these patients.

Tibolone in postmenopausal women with systemic lupus erythematosus: A pilot study

Objective: To determine the influence of the use of tibolone on the frequency of flares of systemic lupus erythematosus (SLE) in postmenopausal patients. Methods: Thirty patients with inactive or controlled SLE were included in the study. Patients were randomized to receive a 12-month course of either tibolona (2.5 mg/day) or placebo. The following were investigated: hypoestrogenism symptoms by Kupperman index, weight; anti-dsDNA antibodies; SLE flares (frequency) assessed by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI); and biochemical profile (total cholesterol, high-density lipoprotein cholesterol [HDL-C], triglycerides, complement components [C3/C4], alpha 1-acid glycoprotein, urea, creatinine, 24-h proteinuria, C-reactive protein and erythrocyte sedimentation rate). Results: The reduction in Kupperman index was greater in the patients using tibolone than in those using placebo. I-lie mean SLEDAI was not different between the groups during the study as well as SLE flare frequency (tibolone: 2/15 [13.3%] vs. placebo: 1/15 [6.7%]; p = 0.54). All cases of flares were considered mild to moderate. Although the groups were similar at the baseline evaluation, after 6 and 12 months of treatment lower values were found in the tibolone group for triglycerides (6 months: 161.6 +/- 30.9 mg/dl vs. 194.4 +/- 46.5: p = 0.04: 12 months 163.7 +/- 29.8 mg/dl vs. 204.1 +/- 49.9 mg/dl; p = 0.02: tibolone vs. placebo group, respectively) and for HDL-C (6 months: 40.7 +/- 10.7 mg/dl vs. 53.4 +/- 16.5; p = 0.02; 12 months: 47.2 +/- 7.9 mg/dl vs. 63.2 +/- 16.3 mg/dl; p < 0.01: tibolone vs. placebo group, respectively). There were no differences between the two groups in any of the remaining variables. Conclusion: In patients with inactive or stable SLE, the short-term use of tibolone did not significantly affect the frequency of flares. In addition, tibolone was well tolerated and effective to control hypoestrogenism related symptoms in SLE patients. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

Increased Capsaicin Receptor TRPV1 in the Peritoneum of Women With Chronic Pelvic Pain

Objective: To investigate the expression of capsaicin receptor [transient receptor potential vanilloid type-1 (TRPV1)] in the peritoneum of women with chronic pelvic pain (CPP). Methods: A case-control study was conducted on 25 women with CPP and 10 controls. Samples of the rectouterine excavation (2 cm 2) were obtained by laparoscopy, fixed in 4% formaldehyde, and underwent immunohistochemistry analysis using rabbit anti-TRPV1 (1:400) polyclonal antibodies and anti-protein gene product 9.5 (PGP 9.5) (1:2000) as a neuronal marker. Ten sequential images of high magnification fields ( x 40) were captured from each slide and the area identified with the antibody was calculated with Kontron V2.0 software. Results: Immunoreactivity to TRPV1 was sparsely detected in the nervous tissue and epithelium of endometriotic lesions. The percent area of immunoreactivity for TRPV1 [expressed as median (range)] was greater in specimens from women with CPP, 1.02% (0.54 to 2.93), than from women without the disease, 0.14% (0.07 to 1.12) (P<0.0001). This greater expression was not secondary to an increase in neuronal fibers because there was also a significant difference in the percent area TRPV1:PGP 9.5 ratio between women with CPP, 1.18 (0.26 to 4.63), and controls, 0.15 (0.06 to 0.95) (P = 0.0003). Discussion: TRPV1 may play an important role in the maintenance and perpetuation of symptoms in women with CPP. In view of the immunoreactivity detected for TRPV1, the endometriotic lesion may have the ability to interfere with nociception or with the inflammatory peritoneal environment in women with CPP. Further Studies are needed to elucidate the participation of TRPV1 in CPP and its association with endometriosis.

Supplemented tissue culture medium 199 is a better medium for in vitro maturation of oocytes from women with polycystic ovary syndrome women than human tubal fluid

Objective: To compare oocyte maturation, fertilization and cleavage rates, and embryonic developmental quality after culture of human immature oocytes from polycystic ovary syndrome (PCOS) patients in human tubal fluid (HTF) or tissue culture medium (TCM) 199. Design: Prospective, randomized, controlled trial. Setting: University hospital. Patient(s): Thirteen women undergoing 23 in vitro maturation cycles, from whom 119 oocytes were retrieved. Intervention(s): Cumulus-enclosed germinal vesicle-stage oocytes matured in TCM-199-supplemented or HTF-supplemented media. Main Outcome Measure(s): Oocyte maturation and fertilization rates, embryonic developmental quality. Result(s): Significant differences were observed between TCM 199 and HTF regarding maturation rate (82% vs. 56.9%), fertilization rate (70% vs. 39.4%), and embryo quality (81.3% vs. 41.7%). Conclusion(S): Human tubal fluid medium, although widely used for embryo fertilization and maintenance in IVF techniques, is not,in appropriate medium for the maturation of oocytes obtained from PCOS patients in nonstimulated cycles.
