RESUMO

INTRODUCTION: Mitotane is an adrenolytic drug that is used as an adjuvant to treat adrenocortical carcinoma. This study aimed to evaluate the clinical course and pathogenetic mechanisms underlying ovarian cyst formation in women of reproductive age diagnosed with adrenocortical carcinoma and being treated with mitotane as an adjuvant to surgery. MATERIAL AND METHODS: Five women presented with stage III-IV adrenocortical carcinoma and ovarian cyst formation during mitotane treatment. The clinical course of the disease was followed during and after treatment. The effects of mitotane on progesterone production and cell proliferation were studied in cultured human ovarian granulosa cells. RESULTS: Computed tomography and vaginal ultrasonography during mitotane treatment repeatedly demonstrated ovarian cysts of varying size without solid intralocular structures. Two women became amenorrheic during the treatment period. After mitotane cessation, the ovarian cysts disappeared and normal menstrual cycles resumed. One woman had an uncomplicated pregnancy two years after mitotane treatment. In one woman, who underwent salpingo-oophorectomy, histological analysis demonstrated benign ovarian cysts. Mitotane impeded the synthesis of progesterone, reduced the stimulatory effect of gonadotropins on progesterone formation, and reduced labeling with [3 H]thymidine in cultured granulosa cells. CONCLUSIONS: Therapeutic concentrations of mitotane are associated with the formation of benign ovarian cysts and amenorrhea. Mitotane-induced suppression of ovarian steroidogenesis and impediment of the proliferative capacity of steroid-producing cells are suggested potential pathogenetic mechanisms underlying mitotane-induced ovarian dysfunction and cyst development. Mitotane treatment does not compromise future ovarian function.

RESUMO

OBJECTIVE: To investigate whether electro-acupuncture or physical exercise influence serum anti-Müllerian hormone (AMH), antral follicle count (AFC) or ovarian volume in women with polycystic ovary syndrome (PCOS). DESIGN: Secondary analyses of a prospective, randomized controlled clinical trial. SETTING: University Hospital, Sweden. PATIENTS: Seventy-four women with PCOS recruited from the general population. INTERVENTIONS: Women with PCOS were randomized to 16 weeks of electro-acupuncture (14 treatments), exercise (at least three times/week), or no intervention. MAIN OUTCOME MEASURES: Serum AMH recorded at baseline, after 16 weeks of intervention, and at follow up at 32 weeks. AFC, and ovarian volume assessed by magnetic resonance imaging at baseline and at follow up at 32 weeks. RESULTS: After 16 weeks of intervention, serum levels of AMH were significantly decreased in the electro-acupuncture group by 17.5% (p < 0.001), and differed from the change in the exercise group. AMH remained decreased by 15% (p = 0.004) also at follow up at 32 weeks, but did not differ from the exercise or the no intervention groups. There was a decrease by 8.5% (p = 0.015) in ovarian volume between baseline and follow up in the electro-acupuncture group, and by 11.7% (p = 0.01) in AFC in the physical exercise group. No other variables were affected. CONCLUSIONS: This study is the first to demonstrate that acupuncture reduces serum AMH levels and ovarian volume. Physical exercise did not influence circulating AMH or ovarian volume. Despite a within-group decrease in AFC, exercise did not lead to a between-group difference.

RESUMO

OBJECTIVE: To characterize ovarian morphology and perfusion by magnetic resonance imaging (MRI) in women with and without polycystic ovary syndrome (PCOS) and to investigate associations with antimüllerian hormone (AMH), free T, and glucose disposal rate (GDR). DESIGN: Explorative cross-sectional study. SETTING: University hospital. PATIENT(S): Fifty-eight women with PCOS and 31 controls from the general population. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Antral follicle count (AFC), ovarian/stromal volume, perfusion, AMH, free T, and GDR. RESULT(S): Antral follicles of 1-3 and 4-6 mm, but not 7-9 mm, were more numerous, and total AFC (1-9 mm) was higher in women with PCOS. Ovarian volume was larger in women with PCOS. AMH and free T were higher and GDR was lower in women with PCOS. All values were more deranged in classic compared with nonclassic PCOS. There was a positive correlation between AMH and AFC, 1-3 mm (r = 0.81), and between AMH and total AFC (r = 0.87). In receiver operating characteristic analyses, the area under the curve was 0.89 for total AFC, 0.86 for AMH, and 0.90 for free T. PCOS was independently associated with AFC and free T but not with AMH or GDR when adjusted for age and body mass index. CONCLUSION(S): Counting antral follicles down to 1 mm in size by MRI yielded higher AFCs than previously reported. AFC, AMH, and free T discriminated with high accuracy between women with PCOS and controls, but AMH was not independently associated with PCOS. CLINICAL TRIAL REGISTRATION NUMBER: NCT00484705.

RESUMO

BACKGROUND: Women with polycystic ovary syndrome (PCOS) have symptoms of depression and anxiety and impaired health related quality of life (HRQoL). Here we test the post-hoc hypothesis that acupuncture and exercise improve depression and anxiety symptoms and HRQoL in PCOS women. METHODS: Seventy-two PCOS women were randomly assigned to 16 weeks of 1) acupuncture (n = 28); 2) exercise (n = 29); or 3) no intervention (control) (n = 15). Outcome measures included: change in Montgomery Åsberg Depression Rating Scale (MADRS-S), Brief Scale for Anxiety (BSA-S), Swedish Short-Form 36 (SF-36), and PCOS Questionnaire (PCOSQ) scores from baseline to after 16-week intervention, and to 16-week post-intervention follow-up. RESULTS: A reduction in MADRS-S and BSA-S from baseline to 16-weeks post-intervention follow-up was observed for the acupuncture group. The SF-36 domains role physical, energy/vitality, general health perception and the mental component of summary scores improved in the acupuncture group after intervention and at follow-up. Within the exercise group the role physical decreased after treatment, while physical functioning and general health perception scores increased at follow-up. The emotion domain in the PCOSQ improved after 16-weeks of intervention within all three groups, and at follow-up in acupuncture and exercise groups. At follow-up, improvement in the infertility domain was observed within the exercise group. CONCLUSION: There was a modest improvement in depression and anxiety scores in women treated with acupuncture, and improved HRQoL scores were noted in both intervention groups. While not a primary focus of the trial, these data suggest continued investigation of mental health outcomes in women treated for PCOS.

RESUMO

OBJECTIVE: To investigate the possible effects of low-frequency electroacupuncture (EA) and physical exercise on markers of coagulation and fibrinolysis, insulin sensitivity, and adipose tissue characteristics in women with polycystic ovary syndrome (PCOS). DESIGN: Secondary analyses of a prospective, randomized controlled clinical trial. SETTING: Department of Physiology and Department of Obstetrics and Gynecology, University of Gothenburg. PATIENT(S): Eighty-four women with PCOS were randomized. INTERVENTION(S): Women with PCOS were randomized to 16 weeks of low-frequency EA (14 treatments), physical exercise (at least 3 times/wk), or no intervention. MAIN OUTCOME MEASURE(S): Anthropometrics, circulating coagulation and fibrinolytic markers, insulin sensitivity (euglycemic hyperinsulinemic clamp), hemodynamics, and adipose tissue morphology/function recorded at baseline, after 16 weeks of intervention, and after a 16-week follow-up. RESULT(S): In the low-frequency EA group, circulating plasminogen activator inhibitor 1 activity decreased by 21.8% after 16 weeks of intervention and by 31.1% at the 16-week follow-up and differed from the physical exercise and the no intervention groups. The EA group had decreases in circulating fibrinogen and tissue plasminogen activator (t-PA), sagittal diameter, and diastolic blood pressure after treatment, and fibrinogen remained lower at the 16-week follow-up. In the physical exercise group, lipoprotein lipase activity increased and diastolic blood pressure decreased after treatment, and both diastolic and systolic blood pressure were lower at follow-up. No other variables were affected. CONCLUSION(S): Low-frequency EA counteracted a possible prothrombotic state in women with PCOS, as reflected by a decrease in plasminogen activator inhibitor 1 activity. Despite within-group improvements, there were no between-group differences in anthropometric, metabolic, or hemodynamic variables after 16 weeks of EA or physical exercise at the dose/intensity studied.

RESUMO

CONTEXT: Affective symptoms are poorly understood in polycystic ovary syndrome (PCOS). Clinical signs of hyperandrogenism and high serum androgens are key features in PCOS, and women with PCOS are more likely to be overweight or obese, as well as insulin resistant. Further, PCOS is associated with high sympathetic nerve activity. OBJECTIVE: To elucidate if self-reported hirsutism, body mass index (BMI) and waistline, circulating sex steroids, sex hormone-binding globulin (SHBG), insulin sensitivity and sympathetic nerve activity are associated with depression and anxiety-related symptoms in women with PCOS. DESIGN AND METHODS: Seventy-two women with PCOS, aged 21-37 years, were recruited from the community. Hirsutism was self-reported using the Ferriman-Gallway score. Serum estrogens, sex steroid precursors, androgens and glucuronidated androgen metabolites were analyzed by gas and liquid chromatography/mass spectroscopy (GC-MS/LC-MS/MS) and SHBG by chemiluminiscent microparticle immunoassay (CMIA). Insulin sensitivity was measured with euglycemic hyperinsulinemic clamp. Sympathetic nerve activity was measured with microneurography. Symptoms of depression and anxiety were self-reported using the Montgomery Åsberg Depression Rating Scale (MADRS-S) and the Brief Scale for Anxiety (BSA-S). RESULTS: Circulating concentrations of testosterone (T) (P=0.026), free T (FT) (P=0.025), and androstane-3α 17ß-diol-3glucuronide (3G) (P=0.029) were lower in women with depression symptoms of potential clinical relevance (MADR-S≥11). The odds of having a MADRS-S score ≥11 were higher with lower FT and 3G. No associations with BSA-S were noted. CONCLUSION: Lower circulating FT and 3G were associated with worse self-reported depression symptoms. The relationship between mental health, sex steroids and corresponding metabolites in PCOS requires further investigation.

RESUMO

CONTEXT: Studies of fibrinolysis/coagulation status in women with polycystic ovary syndrome (PCOS) are contradictory. OBJECTIVES: The aim of the study was to investigate whether women with PCOS have disturbed circulating levels of fibrinolysis/coagulation markers and, if so, whether the disturbances are related to hemodynamics, metabolic variables, sex steroids, SHBG, lipids, and inflammatory variables in women with PCOS. DESIGN/MAIN OUTCOME MEASURES: Anthropometric variables, hemodynamics, circulating hemostatic and inflammatory markers, and serum lipid profile were measured in women with untreated PCOS (n = 74) and controls (n = 31). RESULTS: After adjustments for age and body mass index (BMI), circulating plasminogen activator inhibitor 1 (PAI-1) activity and fibrinogen levels were higher in women with PCOS than controls; lipid profile, blood pressure, and levels of D-dimer, von Willebrand factor, factor VIII, tissue plasminogen activator, and inflammatory markers were comparable in the two groups. In multiple linear regression analyses including women with PCOS, low SHBG and high insulin predicted high PAI-1 activity (R(2) = 0.526; P < 0.001); elevated high-sensitivity C-reactive protein and soluble E-selectin in combination with heart rate predicted high fibrinogen (R(2) = 0.333; P < 0.001). Differences in PAI-1 activity were not significant after adjustments for age, BMI, SHBG, and insulin. CONCLUSIONS: PCOS is characterized by a prothrombotic state, as reflected by increased PAI-1 activity and fibrinogen, without signs of dyslipidemia or a proinflammatory state. Low SHBG and high insulin may partly explain the BMI-independent difference in PAI-1 activity between women with PCOS and controls. High-sensitivity C-reactive protein and E-selectin may be involved in regulating fibrinogen in PCOS.

RESUMO

Polycystic ovary syndrome (PCOS), the most common endocrine disorder in women of reproductive age, is characterized by hyperandrogenism, oligo/amenorrhea, and polycystic ovaries. We aimed to determine whether low-frequency electro-acupuncture (EA) would decrease hyperandrogenism and improve oligo/amenorrhea more effectively than physical exercise or no intervention. We randomized 84 women with PCOS, aged 18-37 yr, to 16 wk of low-frequency EA, physical exercise, or no intervention. The primary outcome measure changes in the concentration of total testosterone (T) at week 16 determined by gas and liquid chromatography-mass spectrometry was analyzed by intention to treat. Secondary outcome measures were changes in menstrual frequency; concentrations of androgens, estrogens, androgen precursors, and glucuronidated androgen metabolites; and acne and hirsutism. Outcomes were assessed at baseline, after 16 wk of intervention, and after a 16-wk follow-up. After 16 wk of intervention, circulating T decreased by -25%, androsterone glucuronide by -30%, and androstane-3α,17ß-diol-3-glucuronide by -28% in the EA group (P = 0.038, 0.030, and 0.047, respectively vs. exercise); menstrual frequency increased to 0.69/month from 0.28 at baseline in the EA group (P = 0.018 vs. exercise). After the 16-wk follow-up, the acne score decreased by -32% in the EA group (P = 0.006 vs. exercise). Both EA and exercise improved menstrual frequency and decreased the levels of several sex steroids at week 16 and at the 16-wk follow-up compared with no intervention. Low-frequency EA and physical exercise improved hyperandrogenism and menstrual frequency more effectively than no intervention in women with PCOS. Low-frequency EA was superior to physical exercise and may be useful for treating hyperandrogenism and oligo/amenorrhea.

RESUMO

CONTEXT: Females with congenital adrenal hyperplasia (CAH) due to a CYP21A2 deficiency are exposed to androgens during fetal development, resulting in virilization of the external genitalia. Little is known about how these women feel that the disease has affected their lives regarding surgery and psychosexual adaptation. OBJECTIVE: Our objective was to investigate the correlation between the surgical results, the self-perceived severity of the disease, and satisfaction with sexual life and relate the results to the CYP21A2 genotype. DESIGN AND PARTICIPANTS: Sixty-two Swedish women with CAH and age-matched controls completed a 120-item questionnaire, and a composite score for sexual function was constructed. The surgical outcome, including genital appearance and clitoral sensitivity, was evaluated by clinical examination. The patients were divided into four CYP21A2 genotype groups. RESULTS: The sexual function score, but not for genital appearance, was higher in the patients satisfied with their sexual life. This was also true of the patients who were satisfied with the surgical result. There were discrepancies between the patients' perception of the impact of the condition on their sexual life and what health professionals would assume from clinical examination. The patients in the null genotype group scored lower on sexual function and satisfaction with their sexual life and had more surgical complications, also compared with the slightly less severe I2-splice genotype group. CONCLUSION: Our data show that the null genotype group was considerably more affected by the condition than the other groups and should be regarded as a subgroup, both psychologically and from a surgical perspective. Genotyping adds clinically valuable information.

RESUMO

CONTEXT: Despite the high prevalence of hyperandrogenemia, the principal biochemical abnormality in women with polycystic ovary syndrome (PCOS), a definitive endocrine marker for PCOS has so far not been identified. OBJECTIVE: To identify a tentative diagnostic marker for PCOS, we compared serum levels of sex steroids, their precursors, and main metabolites in women with PCOS and controls. DESIGN AND METHODS: In this cross-sectional study of 74 women with PCOS and 31 controls, we used gas and liquid chromatography/mass spectrometry to analyze serum sex steroid precursors, estrogens, androgens, and glucuronidated androgen metabolites; performed immunoassays of SHBG, LH, and FSH; and calculated the LH/FSH ratio. RESULTS: Androgens and estrogens, sex steroid precursors, and glucuronidated androgen metabolites were higher in women with PCOS than in controls. In multivariate logistic regression analyses, estrone and free testosterone were independently associated with PCOS. The odds ratios per sd increase were 24.2 for estrone [95% confidence interval (CI), 4.0-144.7] and 12.8 for free testosterone (95% CI, 3.1-53.4). In receiver operating characteristic analyses, the area under curve was 0.93 for estrone (95% CI, 0.88-0.98) and 0.91 for free testosterone (95% CI, 0.86-0.97), indicating high sensitivity and specificity. CONCLUSION: Women with PCOS have elevated levels of sex steroid precursors, estrogens, androgens, and glucuronidated androgen metabolites as measured with a specific and sensitive mass spectrometry-based technique. The combination of elevated estrone (>50 pg/ml) and free testosterone (>3.3 pg/ml) appeared to discriminate with high sensitivity and specificity between women with and without PCOS.

RESUMO

We have recently shown that polycystic ovary syndrome (PCOS) is associated with high muscle sympathetic nerve activity (MSNA). Animal studies support the concept that low-frequency electroacupuncture (EA) and physical exercise, via stimulation of ergoreceptors and somatic afferents in the muscles, may modulate the activity of the sympathetic nervous system. The aim of the present study was to investigate the effect of these interventions on sympathetic nerve activity in women with PCOS. In a randomized controlled trial, 20 women with PCOS were randomly allocated to one of three groups: low-frequency EA (n = 9), physical exercise (n = 5), or untreated control (n = 6) during 16 wk. Direct recordings of multiunit efferent postganglionic MSNA in a muscle fascicle of the peroneal nerve before and following 16 wk of treatment. Biometric, hemodynamic, endocrine, and metabolic parameters were measured. Low-frequency EA (P = 0.036) and physical exercise (P = 0.030) decreased MSNA burst frequency compared with the untreated control group. The low-frequency EA group reduced sagittal diameter (P = 0.001), while the physical exercise group reduced body weight (P = 0.004) and body mass index (P = 0.004) compared with the untreated control group. Sagittal diameter was related to MSNA burst frequency (Rs = 0.58, P < 0.005) in the EA group. No correlation was found for body mass index and MSNA in the exercise group. There were no differences between the groups in hemodynamic, endocrine, and metabolic variables. For the first time we demonstrate that low-frequency EA and physical exercise lowers high sympathetic nerve activity in women with PCOS. Thus, treatment with low-frequency EA or physical exercise with the aim to reduce MSNA may be of importance for women with PCOS.

RESUMO

OBJECTIVE: To study the association between hormonal infertility treatment and ovarian neoplasia. DESIGN: Historical cohort study. SETTING: Three university hospitals in Sweden. PATIENT(S): A total of 2,768 women assessed and treated for infertility and infertility-associated disorders between 1961 and 1975. INTERVENTION(S): Exposed women received clomiphene citrate and/or gonadotropins. MAIN OUTCOME MEASURE(S): Incidence of ovarian neoplasia. RESULT(S): No overall excess risk of invasive ovarian cancer emerged compared with the general population. In women with gonadotropin treatment for non-ovulatory disorders, the risk was elevated (standardized incidence ratio [SIR] = 5.89; 95% confidence interval [CI] 1.91-13.75); four of the five cases reported hCG treatment only, rendering the biological plausibility uncertain. Multivariate analysis within the cohort indicated that treatment with gonadotropins only was associated with an increased risk of invasive cancer (relative risk = 5.28; 95% CI 1.70-16.47). For borderline tumors, a more than threefold overall increase of tumors (SIR = 3.61; 95% CI 1.45-7.44) was noted; women exposed to clomiphene because of ovulatory disorders showed the highest risk (SIR = 7.47; 95% CI 1.54-21.83). CONCLUSION(S): Our findings of increased risk of ovarian cancer after gonadotropins and of borderline tumors after clomiphene treatment need to be interpreted with caution. However, concern is raised, and further research on the long-term safety particularly of modern hormonal infertility treatment in IVF programs is warranted.

RESUMO

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disturbance among women of reproductive age and is proposed to be linked with size at birth and increased prevalence of cardiovascular disease. A disturbance in the sympathetic nervous system may contribute to the etiology of PCOS. This study evaluates sympathetic outflow in PCOS and its relation to size at birth. Directly recorded sympathetic nerve activity to the muscle vascular bed (MSNA) was obtained in 20 women with PCOS and in 18 matched controls. Ovarian ultrasonographic evaluation, biometric, hormonal, and biochemical parameters were measured, and birth data were collected. Women with PCOS had increased MSNA (30 +/- 8 vs. 20 +/- 7 burst frequency, P < 0.0005) compared with controls. MSNA was positively related to testosterone (r = 0.63, P < 0.005) and cholesterol (r = 0.55, P = 0.01) levels in PCOS, which, in turn, were not related to each other. Testosterone level was a stronger predictor of MSNA than cholesterol. Birth size did not differ between the study groups. This is the first study to directly address sympathetic nerve activity in women with PCOS and shows that PCOS is associated with high MSNA. Testosterone and cholesterol levels are identified as independent predictors of MSNA in PCOS, although testosterone has a stronger impact. The increased MSNA in PCOS may contribute to the increased cardiovascular risk and etiology of the condition. In this study, PCOS was not related to size at birth.

RESUMO

CONTEXT: In congenital adrenal hyperplasia (CAH) caused by different mutations, feminizing surgery is mostly performed in childhood, and many patients are lost to follow-up. OBJECTIVE/PATIENTS: A follow-up study on 62 CAH women aged 18-63 yr and 62 age-matched controls to correlate findings of both operative method and mutation was performed. DESIGN: Semistructured interviews were performed in cases and controls, as well as a gynecological examination in the cases. The results were correlated with disease-causing mutations and earlier surgical procedures if performed. SETTING: The study was conducted at university hospital referral clinics. MAIN OUTCOME MEASURES: Gynecological examination in all cases correlated to previous surgery (n = 49), type of mutation, and questionnaire responses. RESULTS: Half of the CAH women claimed that the disease affected their sex life. The women were less satisfied with their genitals, whether operated or not. Clitoris size and functions were affected by the surgical method. Five women had a clinically evident vaginal stenosis on examination. However, almost half of patients experienced a narrow vagina. The overall psychosexual aspects of life were affected in these patients with later sexual debut, fewer pregnancies and children, and an increased incidence of homosexuality. These quality of life factors were correlated to the severity of the mutations. CONCLUSIONS: The overall quality of life in adult women with CAH is affected both by the type of mutation and operative procedure. Indications for clitoroplasty should be restrictive. Medical, surgical, and psychological treatment should be centralized.

RESUMO

BACKGROUND: The primary aims were to compare the pain-relieving effect and post-operative well-being between electro-acupuncture analgesia (EA) and conventional analgesia (CA) comprising opiates. Further aims were to compare time for mobilization, and costs for time and drug consumption. METHODS: In all, 160 women undergoing IVF were randomized, according to a computer-generated list, to EA or CA. Well-being was evaluated with the State Trait Anxiety Inventory (STAI). Pain and subjective expectations and experiences were recorded on a visual analogue scale (VAS). Time and drug consumption were recorded. RESULTS: Although VAS pain ratings were significantly higher at oocyte aspiration (P < 0.0001) and after retrieval (P < 0.01) in the EA than in the CA group, they were similar 60 min after surgery. Both groups had similar STAI well-being scores. The EA group was significantly less tired and confused than the CA group after oocyte aspiration. No significant differences in time and costs for drug consumption were noted. CONCLUSION: EA cannot generally be recommended as a pain-relieving method at oocyte aspiration but might be an alternative for women desiring a non-pharmacological method. An advantage of EA is less post-operative tiredness and confusion compared with CA.

RESUMO

This article summarizes the experience gained so far of uterine artery embolization (UAE) for symptomatic fibroids, reviewing publications related to this issue. More than 10 years have past since Ravina et al started to treat uterine fibroids with UAE. To date thousands of women have been embolized with excellent results and few serious complications. UAE is a successful alternative to hysterectomy for women wishing uterine preservation. Several cases of pregnancy and partus have been reported after UAE, and the method may be considered in women desiring future fertility, if the only remaining surgical option is complicated multiple myomectomy or hysterectomy. So far, recurrence after initially successful UAE has not been reported, but long-term results are yet to be determined.

RESUMO

Androgens are suggested to interact with leptin production and with insulin sensitivity in both polycystic ovary syndrome (PCOS) and obesity. The aim of the study was to follow these interactions along with two forms of antiandrogen treatment. Twenty women with PCOS were treated with ethinylestradiol and high dose of cyproteroneacetate (EE-CA) and 8 with the gonadotrophin-releasing hormone (GnRH) analogue goserelin for 6 months. The patients were divided into a low and a high body weight group and compared with a group of overweight women without PCOS. Both treatments resulted in a significant reduction of free testosterone but the concentration of leptin remained unchanged. EECA treatment resulted in deterioration and GnRH in improvement of insulin sensitivity. Serum leptin correlated only with body weight and body fat. It is concluded that leptin levels do not adequately reflect changes in insulin sensitivity or androgen levels after short-term antiandrogen or antigonadotropin treatment.

RESUMO

Previous studies on the effect of repeated electro-acupuncture (EA) treatments in rats with steriod-induced polycystic ovaries (PCO), EA has been shown to modulate nerve growth factor (NGF) concentration in the ovaries as well as corticotropin releasing factor (CRF) in the median eminence (ME). In the present study we tested the hypothesis that repeated EA treatments modulates sympathetic nerve activity in rats with PCO. This was done by analysing endothelin-1 (ET-1), a potent vasoconstrictor involved in ovarian functions, as well as NGF and NGF mRNA expression involved in the pathophysiological process underlying steroid-induced PCO. The main result in the present study was that concentrations of ET-1 in the ovaries were significantly lower in the PCO group receiving EA compared with the healthy control group (p < 0.05). In the hypothalamus, however, ET-1 concentrations were found to be significantly higher in the PCO group receiving EA than in the healthy control group (p < 0.05). Concentrations of ovarian NGF protein were significantly higher in the PCO control group compared with the healthy control group (p < 0.001), and these concentrations decreased significantly after repeated EA treatments compared with those in the PCO control group (p < 0.05) and were found to be the same as those in the healthy control group. In conclusion, these results indicate that EA modulates the neuroendocrinological state of the ovaries, most likely by modulating the sympathetic nerve activity in the ovaries, which may be a factor in the maintenance of steroid-induced PCO.

RESUMO

The early detection of Y-chromosomal material in women with Turner syndrome (TS) is of great importance due to a relatively high risk of gonadal tumour development. Using fluorescence in situ hybridisation (FISH) analysis, we studied the presence of three different Y-specific sequences (SRY, Ycen and Yq12) in three different tissues (oral epithelial cells, lymphocytes and ovarian tissue) of twelve TS women. We have also described their ovarian histology. Two of the women (17%) had gonadal tumours. In five women where ovarian tissue was available, the presence of Y-chromosomal material in oral epithelial cells and lymphocytes correlated to the presence of Y-chromosomal material in the gonads. We therefore conclude that FISH analysis of oral epithelial cells and/or lymphocytes is a valuable complement to karyotyping for the early detection of Y-chromosomal material in TS women.
