Burn pain is known as the most difficult type of pain to manage. In order to improve patient outcomes, nurses must be aware of burn pain and the conditions that affect it. This study aimed to evaluate the influence of burn-specific pain anxiety on pain experienced by adult outpatients with burns during burn wound care. This was a single-center, prospective, and descriptive study. The study was conducted with 60 adult outpatients with burns between March 2021 and April 2021 in a burn centers' outpatient service in Ankara. Personal information form, burn-specific pain anxiety scale, numerical rating scale, and verbal category scale were used for data collection. The mean age of the patients was 38.50 ± 14.27 years, and 53.33% patients were females. The primary cause of burns was home accidents (80%), and patients generally suffered from scalding-type burns (73.33%). This study demonstrated that the patients reported high pain anxiety associated with burns (59.85 ± 15.71), the mean pain score experienced during wound care was 6.33 ± 2.14 and the pain was primarily classified as disturbing (35%) based on the verbal category scale. In this study, it was found that burn-specific pain anxiety affects the pain experienced during burn wound care in adults receiving outpatient treatment. Hence, nurses should provide effective pain management to patients with burn injuries. In addition, the inclusion of anxiety-reducing practices in the care plans of such patients is recommended, and further studies are needed to identify and meet the care needs of patients with severe burns.

Patients with burns should be provided with holistic nursing care that considers all systems of the body. The Neuman Systems Model (NSM) is especially suited to holistic care as it proposes an open system approach and addresses five major interacting variables. This study aimed to investigate the applicability of the NSM when caring for a patient with electrical burns. In this case study, we planned and applied nursing care for a 20-year-old man with electrical burns based on the NSM. The study was conducted between November 25, 2018, and January 10, 2019. We used the six-item Neuman Diagnostic Tool (NDT) developed by Neuman in our interviews with the patient. We found that the electrical burns had caused multiple physiological, psychological, and sociocultural problems for our patient, most of which were physical problems, including the burn injury and subsequent limb amputation. The NDT guided our data collection and aided in our ability to determine stressors and formulate appropriate nursing diagnoses. The NSM strengthened the patient's flexible line of defense for coping individually and facilitated the identification of deficiencies in the normal and resistance lines of defense. The NSM provides a theoretical framework for nurses caring for patients with burns where entire systems are affected.

Nausea and vomiting are common postoperative complications that occur within the first 24 h in adults. Clinical practice guidelines and a Cochrane review recommend stimulating the P6 acupoint to prevent or reduce postoperative nausea and vomiting. However, there are currently no standards and optimal timing is not known.The purpose of this study was to evaluate the effect of acupressure application on the P6 acupoint, using acupressure wristbands, in the prevention of postoperative nausea and vomiting and the antiemetic drug requirement in patients who had high postoperative nausea and vomiting risk related to laparoscopic cholecystectomy.This was a longitudinal, randomized controlled clinical study.The study was conducted in the general surgery department of a training and research hospital (105 beds), from March 2015 to March 2016.A total of 111 female patients who underwent laparoscopic surgery were divided into three groups of 37, using a block randomization method.Training on acupressure wristband use was provided to the intervention group and an acupressure wristband with a plastic cap was placed at the P6 acupoint. A wristband with the same appearance as the acupressure wristband, but without a cap, was used in the placebo group. No intervention was used in the control group. The wristband was placed approximately one hour before the surgery and removed six hours after the surgery in both the intervention and placebo groups. The data were collected at the 2nd, 6th, and 24th postoperative hours.The application of the acupressure wristband to the P6 acupoint in patients who underwent laparoscopic cholecystectomy was found to be more effective in decreasing the severity of nausea at the 2nd postoperative hour and the nausea incidence at 2-6 h, postoperatively, when compared to the placebo group (p 0.05). However, there was no statistically significant difference between the intervention group and the control group. Therefore, acupressure application to the P6 acupoint was not found to be clinically effective in decreasing postoperative vomiting, antiemetic drug requirement, and in decreasing pain, anxiety, or the need for analgesic drugs (p 0.05).We did not find the stimulation of the P6 acupoint with an acupressure wristband to be clinically effective in reducing postoperative nausea and vomiting or antiemetic drug requirement in patients who underwent laparoscopic cholecystectomy.

This study aimed to evaluate the efficacy and adverse effects of dienogest for the treatment of endometriomas. Dienogest (2 mg/day) was administered to patients with endometrioma continuously through the 6-month study period. The patients were prospectively examined on the efficacy and side effects at baseline, at third months, and sixth months of the treatment. Twenty-four out of 30 patients were able to complete the study. The mean volume of the endometrioma decreased significantly from 112.63 ± 161.31 cm³ at baseline to 65.47 ± 95.69 cm³ at a 6-month follow-up (-41%) (

Since burns affect body image, they cause appearance anxiety. Interventions designed to reduce appearance anxiety that can cause psychological problems such as depression are important. This study aimed to determine the social appearance anxiety of individuals following burns and the factors affecting it and to examine the relationship between social appearance anxiety and perceived social support.This descriptive study was conducted between November 2018 and November 2019 with 106 adult patients with burns. Data were collected using a Personal Information Form, the Social Appearance Anxiety Scale, and the Multidimensional Scale of Perceived Social Support. Shapiro-Wilk test, Independent Two Samples T-Test, One Way Analysis of Variance, Duncan's test, Pearson's correlation analysis, multiple linear regression analysis, the Q-Q plot, and the Durbin-Watson statistics were used in data analysis.The social appearance anxiety scores were moderate (39.38 ± 17.71). Being single; having a high level of education; burns on the face, head, or neck; burn-related amputation; and passing the one-week after injury period were found to significantly increase social appearance anxiety (p0.05). Although the perceived social support scores of the individuals with burns were high (68.34 ± 18.08), they were found to have no correlation with social appearance anxiety (p0.05).The results of this study show that social support does not affect social appearance anxiety. In this respect, we recommend that interventions such as reconstruction and professional psychological support initiatives be prioritized for individuals with burn trauma who are evaluated to have high social appearance anxiety by the appearance anxiety scales.

BACKGROUND Polycystic ovary syndrome (PCOS) is the most frequent cause of anovulatory infertility. In women with PCOS, effective ovulation induction serves as an important first-line treatment for anovulatory infertility. Individual participant data (IPD) meta-analysis is considered as the gold standard for evidence synthesis which provides accurate assessments of outcomes from primary randomised controlled trials (RCTs) and allows additional analyses for time-to-event outcomes. It also facilitates treatment–covariate interaction analyses and therefore offers an opportunity for personalised medicine. OBJECTIVE AND RATIONALE We aimed to evaluate the effectiveness of different ovulation induction agents, in particular letrozole alone and clomiphene citrate (CC) plus metformin, as compared to CC alone, as the first-line choice for ovulation induction in women with PCOS and infertility, and to explore interactions between treatment and participant-level baseline characteristics. SEARCH METHODS We searched electronic databases including MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials up to 20 December 2018. We included RCTs comparing the following interventions with each other or placebo/no treatment in women with PCOS and infertility: CC, metformin, CC plus metformin, letrozole, gonadotrophin and tamoxifen. We excluded studies on treatment-resistant women. The primary outcome was live birth. We contacted the investigators of eligible RCTs to share the IPD and performed IPD meta-analyses. We assessed the risk of bias by using the Cochrane risk of bias tool for RCTs. OUTCOMES IPD of 20 RCTs including 3962 women with PCOS were obtained. Six RCTs compared letrozole and CC in 1284 women. Compared with CC, letrozole improved live birth rates (3 RCTs, 1043 women, risk ratio [RR] 1.43, 95% confidence interval [CI] 1.17–1.75, moderate-certainty evidence) and clinical pregnancy rates (6 RCTs, 1284 women, RR 1.45, 95% CI 1.23–1.70, moderate-certainty evidence) and reduced time-to-pregnancy (6 RCTs, 1235 women, hazard ratio [HR] 1.72, 95% CI 1.38–2.15, moderate-certainty evidence). Meta-analyses of effect modifications showed a positive interaction between baseline serum total testosterone levels and treatment effects on live birth (interaction RR 1.29, 95% CI 1.01–1.65). Eight RCTs compared CC plus metformin to CC alone in 1039 women. Compared with CC alone, CC plus metformin might improve clinical pregnancy rates (8 RCTs, 1039 women, RR 1.18, 95% CI 1.00–1.39, low-certainty evidence) and might reduce time-to-pregnancy (7 RCTs, 898 women, HR 1.25, 95% CI 1.00–1.57, low-certainty evidence), but there was insufficient evidence of a difference on live birth rates (5 RCTs, 907 women, RR 1.08, 95% CI 0.87–1.35, low-certainty evidence). Meta-analyses of effect modifications showed a positive interaction between baseline insulin levels and treatment effects on live birth in the comparison between CC plus metformin and CC (interaction RR 1.03, 95% CI 1.01–1.06). WIDER IMPLICATIONS In women with PCOS, letrozole improves live birth and clinical pregnancy rates and reduces time-to-pregnancy compared to CC and therefore can be recommended as the preferred first-line treatment for women with PCOS and infertility. CC plus metformin may increase clinical pregnancy and may reduce time-to-pregnancy compared to CC alone, while there is insufficient evidence of a difference on live birth. Treatment effects of letrozole are influenced by baseline serum levels of total testosterone, while those of CC plus metformin are affected by baseline serum levels of insulin. These interactions between treatments and biomarkers on hyperandrogenaemia and insulin resistance provide further insights into a personalised approach for the management of anovulatory infertility related to PCOS.

Introduction and Purpose: The aim of this study is to investigate the factors affecting University students' attitudes toward aesthetic surgery. Materials and Methods: This descriptive study was carried out in the spring semester of the 2018-2019 academic year with the students of the nursing Karabuk University. A form determining the sociodemographic characteristics of the students, the Cosmetic Surgery Acceptance Scale, and the Social Appearance Anxiety Scale were used to collect the study data. Results: The mean age of the students participating in the study was 21 ± 1.9 years, the mean body mass index was 22.54 ± 3.8, 72.5% were female, and 97.2% were single. The mean scores of the students obtained from the Cosmetic Surgery Acceptance Scale and Social Appearance Anxiety Scale were 45.73 ± 17.68, 34.85 ± 10.05, respectively. A significant relationship was determined between the mean of the Cosmetic Surgery Acceptance Scale and the ages of the students (P < 0.0001). In addition, there was a positive and strong relationship between the mean scores of the sub-dimensions of the Cosmetic Surgery Acceptance Scale (personal, social, and intellectual levels) and the mean score of the Social Appearance Anxiety Scale (P < 0.0001). Conclusion: In this study, it was determined that age and social appearance anxiety among university students are the factors that increase the possibility of opting for aesthetic surgery. Before aesthetic surgery interventions, determining psychological factors such as aging anxiety and social appearance anxiety that affect attitude toward aesthetic surgery in psychosocial evaluations and integrating the necessary interventions into nursing care will be beneficial in evaluating the suitability of patients for surgical intervention more accurately, applying more qualified nursing care, and increasing patient satisfaction.

Aim The aim of this study was to assess the results of conservative treatment of cervical ectopic pregnancy (CEP). Methods We retrospectively reviewed all cervical ectopic pregnancies diagnosed at the present department between January 2010 and July 2015. Patients with CEP who were treated with either systemic or intra-amniotic methotrexate (MTX) injection were included in the study. Results Ten CEP patients were identified. Median maternal age was 33 years (range, 23–40 years). Median gestational age at diagnosis was 47 days (range, 44–58 days). Before treatment, overall mean serum beta-human chorionic gonadotrophin (β-hCG) was 29 706.9 ± 19 695.2 mIU/mL. Mean gestational sac size was 29.0 ± 6.24 mm. Eight patients had viable fetuses with detected cardiac activity. Six patients were treated primarily with systemic MTX, and four were treated with local MTX injection. One patient in the systemic MTX injection group was switched to local MTX treatment due to severe oral ulceration and increasing β-hCG titers after the fourth dose. One patient in the local treatment group had severe hemorrhage 7 days after local MTX. Three of six women achieved spontaneous pregnancy and gave birth to term, healthy infants after treatment. Conclusion Conservative treatment of CEP with both systemic and local MTX is generally successful with regard to maternal morbidity and reproductive function, but these patients must be closely followed due to the small but real risk of late hemorrhage.

Objective Acne is not solely a cosmetic problem. The clinical importance of acne in the estimation of androgen excess disorders is controversial. Recently, the Amsterdam ESHRE/ASRM-sponsored third PCOS Consensus Workshop Group suggested that acne is not commonly associated with hyperandrogenemia and therefore should not be regarded as evidence of hyperandrogenemia. Our aim was to investigate whether acne is a sign of androgen excess disorder or not. Study design This is a cross sectional study that was performed in a university hospital involving 207 women, aged between 18 and 45 years, suffering mainly from acne. The women were assigned as polycystic ovary syndrome (PCOS), idiopathic hirsutism (IH), idiopathic hyperandrogenemia (IHA). Women with acne associated with any of the androgen excess disorders mentioned above were named as hyperandrogenemia associated acne (HAA). Women with acne but without hirsutism and hyperandrogenemia and having ovulatory cycles were named as “isolated acne”. Serum luteinizing hormone, follicle stimulating hormone, estradiol, progesterone, 17-hydroxyprogesterone, dehydroepiandrosterone-sulfate (DHEAS), androstenedione, total testosterone and lipid levels were measured. Results Acne score was similar between the women with isolated acne and HAA. The most common cause for acne was PCOS and only 28% of the women had isolated acne. 114 (55%) women had at least one raised serum androgen level. Conclusions In this study, 72% of acneic women had clinical and/or biochemical hyperandrogenemia. In contrast to the suggestion of ESHRE/ASRM-sponsored third PCOS Consensus Workshop Group, our data indicate that the presence of androgen excess disorders should be evaluated in women presenting with acne.

Objective To investigate whether there is any relation between oxidative stress and the antioxidant system in the development of polycystic ovary syndrome (PCOS) by measuring serum nitric oxide (NO) levels and xanthine oxidase (XO) activity (a generator of reactive oxygen species) and antioxidant status by measuring serum thiol levels and glutathione peroxidase (GSHPx) and paraoxonase 1 (PON1) activities. Design Prospective case-control study. Setting University hospital in Turkey. Sample Thirty women with polycystic ovary syndrome and 20 age- and sex-matched healthy control subjects were included. Methods Serum XO, PON1 and GSHPx activity and NO and thiol levels were determined by spectrophotometric methods. Main outcome measures Activity of serum XO, PON1 and GSH, as well as NO and thiol levels. Results Serum XO activities were higher in women with PCOS than in the control women (p 0.05). Serum PON1 activities were negatively correlated with serum XO activities and NO levels. Conclusion Increased oxidant XO activity and decreased lipid antioxidant PON1 activity, along with the observed negative correlation between these parameters, suggests that women with PCOS are under oxidative stress and that there is XO-mediated lipid peroxidation, which may be related to increased atherosclerosis seen in later life in such women.

Objectives: The aim of the study was to compare the effects of uterine size and surgeon experience on the surgical out­comes of laparoscopically-assisted vaginal hysterectomy (LAVH) for benign gynecological conditions. Material and methods: This was a retrospective analysis of 184 LAVH cases. All hysterectomies were performed by the same surgeon and divided into two groups, with uterine weight of 280 g (group 2). The groups were compared in terms of the effects of the uterine size and surgeon experience vs. the operative outcomes (operative time, change in hemoglobin levels, hospital stay, and perioperative complications). Results: No significant differences in mean age, parity, history of chronic systemic diseases and previous surgery history were observed between the two groups. However, operative time was significantly greater in group 2 as compared to group 1 (132.1 ± 42.7 minutes vs. 111.5 ± 30.4 minutes, p < 0.05). There were no differences in the hospital stay and perioperative complications between the two groups. One case of bladder injury occurred in each group and one patient underwent a second laparoscopic surgery for postoperative bleeding in group 2. Greater surgeon experience was demonstrated to be associated with decreased operative bleeding and, consequently, smaller differences between preoperative and postop­erative hemoglobin levels. Operative time was also reduced as the surgeon was getting more experienced but the effect did not reach statistical significance. Conclusions: Our study supports the thesis that LAVH is a safe and effective procedure for managing benign gynecologi­cal conditions. Despite increased operative time, LAVH can be safely performed for enlarged uterus in conjunction with increased surgeon experience.

To compare the surgical outcomes of vaginal hysterectomy and prophylactic oophorectomy in women with a uterine size12 weeks' gestation and 12-20 weeks' gestation, without decensus.In this prospective comparative study, 241 consecutive vaginal hysterectomies were planned for women with benign disease of the uterus. All hysterectomies were performed by the same surgeon (author), and divided into 2 groups: a uterine weight280 g (n=83, 280-1150 g) and a uterine weight280 g (n=158). The 2 groups were compared for success rates of hysterectomy and bilateral oophorectomy vaginally, operative time, change in haemoglobin, haemorrhage, length of hospital stay, operative complications, and febrile morbidity.All 241 hysterectomies were completed successfully vaginally, and no patients required laparotomy or additional procedures in both groups. No significant intra- and post-operative complications requiring admission to the hospital were encountered in either group. Mean operating time was significantly longer in the uteri/=280-g group than in the280-g group (69.4+/-24.4 versus 108.2+/-41.2 min, p0.0001). The rate of intraoperative haemorrhage (8.43 versus 1.2%) and the change in haemoglobin were significantly higher in the/=280-g group compared with the280-g group (p0.01). Significant positive linear correlation between uterine weight and operative time was seen in all 241 hysterectomies (p0.001). The rate of bilateral oophorectomy was similar between the uteri/=280-g group (89.8%) and the280-g group (92.9%). The main intraoperative complication of the 241 vaginal hysterectomies was bladder injury that occurred in 1 case (0.4%) in the280-g group. There were no statistically significant differences in intra- and post-operative complications, febrile morbidity, and postoperative hospital stay between the groups.Our findings demonstrate that despite the prolonged operating time and increased intraoperative blood loss, vaginal hysterectomy can be safely performed on a large uterus. Routine bilateral prophylactic oophorectomy can be performed in all patients who have sufficiently long infundibulopelvic ligaments to permit removal of the entire ovary.

Objecti{dotless}ve: To investigate the prevalence of polycystic ovary syndrome (PCOS) and polycystic ovary (PCO) among premenopausal women with type 2 diabetes mellitus (DM). Desi{dotless}gn: Case-control study of women with type 2 DM. Setti{dotless}ng: Tertiary referral university hospital. Pati{dotless}ent(s): Ninety-two premenopausal women with DM, ?30 years of age, and 20 age- and body mass index-matched healthy premenapousal eumenorrheic women were recruited into the study. Interventi{dotless}on(s): An oral glucose tolerance test was performed according to the American Diabetes Association criteria for each healthy woman. After an overnight fasting, blood samples were obtained for the determination of fasting blood glucose, LH, FSH, free T, androstenedione (A4), 17-hydroxyprogesterone (17-OHP), DHEAS, PRL, free T4, TSH, E2, and sex hormone-binding globulin (SHBG) levels. A GnRH analog (buserelin) test was carried out in 36 patients with DM and PCO (including PCOS subjects), 20 patients with DM without PCO or PCOS, and 20 healthy subjects. Mai{dotless}n Outcome Measure(s): The prevalence of PCO and PCOS in women with type 2 DM. Result(s): Fifty-seven (62%) of diabetic patients had normal ovaries, 31 (33.7%) had PCO, and 4 (4.3%) had PCOS. The women with DM (n = 92) and healthy women (n = 20) had similar basal A4, FSH, E2, 17-OHP, free T, and DHEAS levels. The LH and SHBG levels were lower and the hirsutism score higher in diabetic patients than in healthy women (P

OBJECTIVE: To compare the clinical efficacy and safety of the combination of spironolactone (100 mg/day) plus finasteride (5 mg/day) and spironolactone (100 mg/day) alone in the treatment of hirsutism. PATIENTS AND MEASUREMENTS: Sixty-five hirsute women were randomly assigned to one of these two treatment groups. Hirsutism score was measured according to the modified Ferriman-Gallwey scoring system. Baseline and post-treatment assessments were carried out in each subject by an investigator blinded to the therapy. Both groups had similar demographic properties at baseline. The serum levels of total and free testosterone, dehydroepiandrosterone sulphate and sex hormone-binding globulin were measured at the beginning and after 1 year of therapy. Blood chemistry and side-effects were evaluated during the study. Hirsutism scores were decreased significantly in both groups at the end of the year. RESULTS: The mean percentage change in hirsutism scores from baseline in the spironolactone plus finasteride-treated group (51.3%) was significantly (P

Dexketoprofen trometamol (DT), a nonsteroidal anti-inflammatory drug, is a highly water-soluble salt and active enantiomer of rac-ketoprofen. Its parenteral form is commonly used for acute pain management in emergency departments of our country. Side effects such as diarrhea, indigestion, nausea, stomach pain, and vomiting may be seen after the use of DT. Anaphylactic shock (AS) secondary to infusion of DT is very rare and, to our knowledge, it is the first case report describing this side effect. This case report was presented to emphasize that AS may be seen after the use of DT. Keywords: Anaphylactic shock, Dexketoprofen trometamol, Intravenous infusion (MeSH database)

OBJECTIVE: Numerous studies have found elevated androgen production by the adrenal glands in patients with polycystic ovary syndrome (PCOS). However, the role and the mechanisms responsible for the adrenal androgen excess in women with PCOS are not well understood. DESIGN: Our aim was to compare 17-hydroxyprogesterone (17-OHP), androstenedione, dehydroepiandrosterone sulfate (DHEAS) and cortisol responses to a low dose (1 microg) ACTH stimulation test (LDT) with the responses to a standard dose (250 microg) ACTH stimulation test (SDT) in patients with PCOS. METHODS: Fifty women with PCOS (mean age 25.4+/-0.7 years) and 20 healthy women (mean age 27.3+/-2.2 years) were included in the study. The patients and controls underwent ACTH stimulation tests with 1 microg and 250 microg synthetic ACTH in the follicular phase of their cycles. Venous blood was drawn at 0, 30 and 60 min for determination of serum cortisol, 17-OHP, androstenedione and DHEAS levels. RESULTS: In PCOS subjects, peak and area under the curve (AUC) 17-OHP (9.3+/-0.3 nmol/l, 378.4+/-61 nmol/lx60 min), androstenedione (15.6+/-0.6 nmol/l, 806.4+/-52 nmol/lx60 min) and DHEAS (7.5+/-0.4 micromol/l, 385.6+/-25.5 micromol/lx60 min) responses to SDT were significantly higher than the levels in healthy women (respectively 5.7+/-0.3 nmol/l and 249.4+/-52.2 nmol/lx60 min for 17-OHP; 9.1+/-0.3 nmol/l and 413.7+/-31.6 nmol/lx60 min for androstenedione; 4.3+/-0.4 micromol/l and 224.9+/-24.5 micromol/lx60 min for DHEAS) (P

Tumor necrosis factor alpha (TNF-alpha) and other cytokines have been implicated in the pathogenesis of ovarian hyperstimulation syndrome (OHSS). Pentoxifylline, a methylxanthine derivative, was found to inhibit TNF-alpha synthesis. The aim of this study was to evaluate whether the use of pentoxifylline would prevent the occurrence of OHSS in a rabbit model. Thirteen rabbits were divided into two groups. The first group (n = 6) were given pentoxifylline 15 mg/kg intravenously and the second group (n = 7) were given physiological serum 15 mg/kg before ovulation induction. Ovarian hyperstimulation was induced in rabbits by 200 IU equine chorionic gonadotropin on day 1 and 100 IU human chorionic gonadotropin on day 3. Blood samples were analyzed for TNF-alpha on days 1, 3 and 5. All animals were autopsied on day 6 to evaluate the ovarian weight, ascites formation and histopathological changes. There was no difference between groups regarding weight gain, ascites formation and plasma TNF-alpha levels (p0.05). Ovarian weight and number of ovulations were significantly lower in the pentoxifylline group than the control group (p0.05). Pentoxifylline did not prevent ascites formation despite the observed decrease in ovarian weight and number of ovulations in OHSS in a rabbit model.

Objective Polycystic ovary syndrome (PCOS) is a form of functional ovarian hyperandrogenism and affects approximately 5-10% of women of reproductive age. Insulin resistance and hyperinsulinaemia appear to be almost universal feature of the polycystic ovary syndrome. Abnormal regulation of cytochrome P450c17alpha causes the exaggerated secretion of ovarian androgens in PCOS. The aim of the present study was to determine whether reduction of insulin levels by metformin would attenuate FSH, LH, 17-Hydroxyprogesterone (17-OHP) and androstenedione hyperresponsiveness to buserelin testing in PCOS women. Design The presence of hyperinsulinaemia in 16 women with PCOS was demonstrated by an oral glucose tolerance test (OGTT) and results were compared with 13 healthy women. PCOS women were also evaluated with insulin tolerance test (ITT) for the assessment of insulin sensitivity. FSH, LH, 17-OHP and androstenedione responses to buserelin testing were measured in all the women with PCOS. PCOS patients were given metformin (500 mg, orally, two times daily) for 12 weeks and re-evaluated at the end of the treatment period. Results Women with PCOS were hyperinsulinaemic (basal insulin 92.1+/-14.3 vs. 44.0+/-4.0 pmol/l; AUCinsulin 68087.4+/-8862.3 vs. 13075.5+/-1327.6 pmol/lx120 min) compared with healthy women. Metformin therapy improved menstrual disturbances in 25% of the women with PCOS and also resulted in some improvement in insulin sensitivity and reduced basal and post glucose load insulin levels. However, FSH, LH, 17-OHP and androstenedione responses to buserelin testing were unaltered in response to metformin. Conclusion It is clear that PCOS is often associated with profound insulin resistance and hyperinsulinaemia. These abnormalities explain the increased prevalence of glucose intolerance in women with PCOS and metformin has beneficial effects on insulin sensitivity in women with PCOS. Amelioration of hyperinsulinaemia has no significant effect on ovarian cytochrome P450c17alpha enzyme activity. However, it can be used in obese women with PCOS as an adjuvant therapy and long term studies should be performed to evaluate the endocrine effects of metformin in women with PCOS.

OBJECTIVE: To determine whether metformin. when given to non-diabetic women with polycystic ovary syndrome (PCOS), results in a reduction of insulin resistance and hyperinsulinemia while body weight is maintained. Also we aimed to see whether the reduction in insulin levels attenuates the activity of adrenal P450c17alpha enzyme in patients with PCOS. DESIGN: We investigated the 17-hydroxyprogesterone (17-OHP) and androstenedione responses to ACTH, insulin responses to an oral glucose tolerance test (OGTT) and glucose disposal rate in an insulin tolerance test before and after metformin therapy (500 mg, orally, twice daily, for 12 weeks). METHODS: The presence of hyperinsulinemia in 15 women with PCOS was demonstrated by an OGTT and results were compared with those of 10 healthy women. Insulin sensitivity was measured by the rate of endogenous glucose disposal after i.v. bolus injection of insulin. 17-OHP and androstenedione responses to ACTH were measured in all the women with PCOS and the normal women. RESULTS: Women with PCOS were hyperinsulinemic (102.0+/-13.0 (S.E.M.) VS 46.2+/-4.4 pmol/l) and hyperandrogenemic (free testosterone 15.3+/-1.7 vs 7.9+/-0.6 nmol/l; androstenedione 11.8+/-0.8 vs 8.2+/-0.6 nmol/l) and more hirsute (modified Ferriman-Gallwey score, 17.7+/-1.6 vs 3.0+/-0.3) than healthy women. In addition, women with PCOS had higher 17-OHP and androstenedione responses to ACTH when compared with healthy women. Metformin therapy resulted in some improvement in insulin sensitivity and reduced the basal and post-glucose load insulin levels. But 17-OHP and androstenedione responses to ACTH were unaltered in response to metformin. CONCLUSIONS: PCOS is characterized by hyperactivity of the adrenal P450c17alpha enzyme and insulin resistance. It seems that there is no direct relationship between insulin resistance and adrenal P450c17alpha enzyme dysregulation.

The aim of this study was to compare the clinical efficacy and safety of low dose cyproterone acetate-estrogen combination (Diane(R)) and the 5 alpha-reductase inhibitor finasteride in the treatment of hirsutism. Fourty-two women with hirsutism were included in the study. Twenty-one patients treated with cyproterone acetate (CPA) 2 mg and ethinyl estradiol (E) 35 mu g daily on days 5-25 of the menstrual cycle, 21 with finasteride 5 mg daily. Hirsutism score, hormone levels, multiscreen blood chemistry and side effects were evaluated at three-monthly intervals for 9 months. A significant decrease in hirsutism score as compared to baseline was observed after 9 months with either CPA+E (Diane(R)) (mean +/- SE, 15.81+/-1.19 vs 8.38+/-1.21) or finasteride treatment (17.81+/-1.05 vs 10.86+/-0.91) (p
