[PMID: 38033366 PMCID: PMC10682119 DOI: 10.1016/j.mtbio.2023.100849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 10/24/2023] [Accepted: 10/26/2023] [Indexed: 12/02/2023] Open
Abstract
There is a high demand for an optimal drug delivery system to treat androgenetic alopecia. Topical application of ISX9, which is a neurogenesis inducer, has been found to stimulate hair follicle (HF) regrowth by upregulating the Wnt/β-catenin signaling pathway, an essential pathway involved in initiating HF growth and development. In the present study, a temperature-sensitive, biopolymer-based, biocompatible, and eco-friendly drug-delivery system was synthesized. This system comprised chitosan-grafted poly(glycidyl methacrylate-co-N-isopropyl acrylamide) (Poly(GMA-co-NIPAAm)@CS-PGNCS) as the shell component and PF127 as the core polymer. The hydrophobic nature of the PF127 block copolymer efficiently dissolved the partially water-soluble drug, ISX9, and the thermos-responsive shell polymer effectively released the drug at a definite skin temperature. The optimized spherical nanoparticles demonstrated the lowest critical solution temperature (LCST) at 32 ± 2 °C with a diameter of 100-250 nm, which delivered encapsulated ISX9 with greater precision than topical ISX9. In a series of in vivo experiments, we demonstrated that ISX9-coated TBNPs upregulated the expression of β-catenin, active β-catenin, Wnt target genes, stemness marker genes, proliferating cell nuclear antigen, HF stem cell markers, and HF markers including VEGF, TGF, and IGF-1 more effectively than topical ISX9. These results suggest that TBNPs could be employed as a platform for effective transdermal delivery of various hydrophobic drugs.

A systematic review and meta-analysis of the association between cyproterone acetate and intracranial meningiomas. Sci Rep 2022; 12:1942. [PMID: 35121790 PMCID: PMC8816922 DOI: 10.1038/s41598-022-05773-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Accepted: 01/17/2022] [Indexed: 12/22/2022] Open
Abstract
The influence of exposure to hormonal treatments, particularly cyproterone acetate (CPA), has been posited to contribute to the growth of meningiomas. Given the widespread use of CPA, this systematic review and meta-analysis attempted to assess real-world evidence of the association between CPA and the occurrence of intracranial meningiomas. Systematic searches of Ovid MEDLINE, Embase and Cochrane Controlled Register of Controlled Trials, were performed from database inception to 18th December 2021. Four retrospective observational studies reporting 8,132,348 patients were included in the meta-analysis. There was a total of 165,988 subjects with usage of CPA. The age of patients at meningioma diagnosis was generally above 45 years in all studies. The dosage of CPA taken by the exposed group (n = 165,988) was specified in three of the four included studies. All studies that analyzed high versus low dose CPA found a significant association between high dose CPA usage and increased risk of meningioma. When high and low dose patients were grouped together, there was no statistically significant increase in risk of meningioma associated with use of CPA (RR = 3.78 [95% CI 0.31–46.39], p = 0.190). Usage of CPA is associated with increased risk of meningioma at high doses but not when low doses are also included. Routine screening and meningioma surveillance by brain MRI offered to patients prescribed with CPA is likely a reasonable clinical consideration if given at high doses for long periods of time. Our findings highlight the need for further research on this topic.

Abstract
The approach to hyperandrogenism in women varies depending on the woman's age and severity of symptoms. Once tumorous hyperandrogenism is excluded, the most common cause is PCOS. Hirsutism is the most common presenting symptom. The woman's concern about her symptoms plays an important role in the management of disease. Although measurement of testosterone is useful in identifying an underlying cause, care must be taken when interpreting the less accurate assays that are available commercially. Surgical resection is curative in tumorous etiologies, whereas medical management is the mainstay for non-tumorous causes.

Abstract
The gut microbiota is a complex system, consisting of a dynamic population of microorganisms, involved in the regulation of the host's homeostasis. A vast number of factors are driving the gut microbiota composition including diet, antibiotics, environment, and lifestyle. However, in the past decade, a growing number of studies also focused on the role of sex in relationship to changes in the gut microbiota composition in animal experiments as well as in human beings. Despite the progress in investigation techniques, still little is known about the mechanism behind the observed sex-related differences. In this review, we summarized current knowledge on the sex-dependent differences of the intestinal commensals and discuss the probable direct impact of sex hormones and more indirect effects such as dietary habits or antibiotics. While we have to conclude limited data on specific developmental stages, a clear role for sexual hormones and most probably for testosterone emerges.

Abstract
OBJECTIVE To update the "Evaluation and Treatment of Hirsutism in Premenopausal Women: An Endocrine Society Clinical Practice Guideline," published by the Endocrine Society in 2008. PARTICIPANTS The participants include an Endocrine Society-appointed task force of seven medical experts and a methodologist. EVIDENCE This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation system to describe the strength of recommendations and the quality of evidence. The task force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies. CONSENSUS PROCESS Group meetings, conference calls, and e-mail communications facilitated consensus development. Endocrine Society committees, members, and cosponsoring organizations reviewed and commented on preliminary drafts of the guidelines. CONCLUSION We suggest testing for elevated androgen levels in all women with an abnormal hirsutism score. We suggest against testing for elevated androgen levels in eumenorrheic women with unwanted local hair growth (i.e., in the absence of an abnormal hirsutism score). For most women with patient-important hirsutism despite cosmetic measures (shaving, plucking, waxing), we suggest starting with pharmacological therapy and adding direct hair removal methods (electrolysis, photoepilation) for those who desire additional cosmetic benefit. For women with mild hirsutism and no evidence of an endocrine disorder, we suggest either pharmacological therapy or direct hair removal methods. For pharmacological therapy, we suggest oral combined estrogen-progestin contraceptives for the majority of women, adding an antiandrogen after 6 months if the response is suboptimal. We recommend against antiandrogen monotherapy unless adequate contraception is used. We suggest against using insulin-lowering drugs. For most women who choose hair removal therapy, we suggest laser/photoepilation.

Abstract
OBJECTIVE To provide consensus recommendations for health-care providers on the use of oral contraceptive pills (OCPs) in polycystic ovarian syndrome (PCOS) women in India. PARTICIPANTS Extensive deliberations, discussions, and brainstorming were done with different fraternities (specialists) being involved. These included endocrinologists, gynecologists, reproductive endocrinologists, dermatologists, public health experts, researchers, and a project manager with a team to develop the guideline. EVIDENCE Published literature was retrieved through searches of Medline and The Cochrane Database from January 2003 to December 2017 using appropriate-controlled vocabulary (e.g., oral contraceptive pills, polycystic ovarian syndrome, long term outcomes, infertility). Clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies' publications and data were also reviewed to suggest the recommendations. PROCESS The working group for guideline committee included members from the PCOS Society (India), Indian Society for Assisted Reproduction, The Mumbai Obstetric and Gynecological Society, The Endocrine Society of India, Indian Association of Dermatologists, Venereologists and Leprologists, Cosmetic Dermatology Society (India), Academicians from Medical Colleges, National Institute for Research in Reproductive Health, and a Research Associate. The core team included five reproductive endocrinologists, five gynecologists, five dermatologists, three endocrinologists, two public health experts and one research associate. CONCLUSIONS This consensus statement provides the guidance/recommendations for Indian practitioners regarding the use of OCP in women with PCOS. PCOS is one of the common endocrinopathies encountered in gynecological/endocrine practice. The spectrum of this disorder may range from prepubertal girls with premature pubarche, young girls with hirsutism, acne and anovulatory cycles, married women with infertility, and elderly women. Although obesity is a common feature for most PCOS patients, 'lean PCOS' also exists. For several years, OCPs have played an important role in the symptom management of PCOS women. This is due to the fact that OCPs decrease the luteinizing hormone, reduce androgen production, and increase sex hormone-binding globulin, which binds androgens. Several new formulations of OCPs have been developed to decrease the side effects. This includes use of less androgenic progestins and lower doses of ethinyl estradiol. These consensus recommendations help the health provider to choose the right type of OCPs, which will alleviate the symptoms with least side effects. It also gives insight into the indications, contraindications, and concerns regarding its short, intermediate and long-term use.

Abstract
BACKGROUND Hirsutism occurs in 5% to 10% of women of reproductive age when there is excessive terminal hair growth in androgen-sensitive areas (male pattern). It is a distressing disorder with a major impact on quality of life. The most common cause is polycystic ovary syndrome. There are many treatment options, but it is not clear which are most effective. OBJECTIVES To assess the effects of interventions (except laser and light-based therapies alone) for hirsutism. SEARCH METHODS We searched the Cochrane Skin Group Specialised Register, CENTRAL (2014, Issue 6), MEDLINE (from 1946), EMBASE (from 1974), and five trials registers, and checked reference lists of included studies for additional trials. The last search was in June 2014. SELECTION CRITERIA Randomised controlled trials (RCTs) in hirsute women with polycystic ovary syndrome, idiopathic hirsutism, or idiopathic hyperandrogenism. DATA COLLECTION AND ANALYSIS Two independent authors carried out study selection, data extraction, 'Risk of bias' assessment, and analyses. MAIN RESULTS We included 157 studies (sample size 30 to 80) comprising 10,550 women (mean age 25 years). The majority of studies (123/157) were 'high', 30 'unclear', and four 'low' risk of bias. Lack of blinding was the most frequent source of bias. Treatment duration was six to 12 months. Forty-eight studies provided no usable or retrievable data, i.e. lack of separate data for hirsute women, conference proceedings, and losses to follow-up above 40%.Primary outcomes, 'participant-reported improvement of hirsutism' and 'change in health-related quality of life', were addressed in few studies, and adverse events in only half. In most comparisons there was insufficient evidence to determine if the number of reported adverse events differed. These included known adverse events: gastrointestinal discomfort, breast tenderness, reduced libido, dry skin (flutamide and finasteride); irregular bleeding (spironolactone); nausea, diarrhoea, bloating (metformin); hot flushes, decreased libido, vaginal dryness, headaches (gonadotropin-releasing hormone (GnRH) analogues)).Clinician's evaluation of hirsutism and change in androgen levels were addressed in most comparisons, change in body mass index (BMI) and improvement of other clinical signs of hyperandrogenism in one-third of studies.The quality of evidence was moderate to very low for most outcomes.There was low quality evidence for the effect of two oral contraceptive pills (OCPs) (ethinyl estradiol + cyproterone acetate versus ethinyl estradiol + desogestrel) on change from baseline of Ferriman-Gallwey scores. The mean difference (MD) was -1.84 (95% confidence interval (CI) -3.86 to 0.18).There was very low quality evidence that flutamide 250 mg, twice daily, reduced Ferriman-Gallwey scores more effectively than placebo (MD -7.60, 95% CI -10.53 to -4.67 and MD -7.20, 95% CI -10.15 to -4.25). Participants' evaluations in one study with 20 participants confirmed these results (risk ratio (RR) 17.00, 95% CI 1.11 to 259.87).Spironolactone 100 mg daily was more effective than placebo in reducing Ferriman-Gallwey scores (MD -7.69, 95% CI -10.12 to -5.26) (low quality evidence). It showed similar effectiveness to flutamide in two studies (MD -1.90, 95% CI -5.01 to 1.21 and MD 0.49, 95% CI -1.99 to 2.97) (very low quality evidence), as well as to finasteride in two studies (MD 1.49, 95% CI -0.58 to 3.56 and MD 0.40, 95% CI -1.18 to 1.98) (low quality evidence).Although there was very low quality evidence of a difference in reduction of Ferriman-Gallwey scores for finasteride 5 mg to 7.5 mg daily versus placebo (MD -5.73, 95% CI -6.87 to -4.58), it was unlikely it was clinically meaningful. These results were reinforced by participants' assessments (RR 2.06, 95% CI 0.99 to 4.29 and RR 11.00, 95% CI 0.69 to 175.86). However, finasteride showed inconsistent results in comparisons with other treatments, and no firm conclusions could be reached.Metformin demonstrated no benefit over placebo in reduction of Ferriman-Gallwey scores (MD 0.05, 95% CI -1.02 to 1.12), but the quality of evidence was low. Results regarding the effectiveness of GnRH analogues were inconsistent, varying from minimal to important improvements.We were unable to pool data for OCPs with cyproterone acetate 20 mg to 100 mg due to clinical and methodological heterogeneity between studies. However, addition of cyproterone acetate to OCPs provided greater reductions in Ferriman-Gallwey scores.Two studies, comparing finasteride 5 mg and spironolactone 100 mg, did not show differences in participant assessments and reduction of Ferriman-Gallwey scores (low quality evidence). Ferriman-Gallwey scores from three studies comparing flutamide versus metformin could not be pooled (I² = 62%). One study comparing flutamide 250 mg twice daily with metformin 850 mg twice daily for 12 months, which reached a higher cumulative dosage than two other studies evaluating this comparison, showed flutamide to be more effective (MD -6.30, 95% CI -9.83 to -2.77) (very low quality evidence). Data showing reductions in Ferriman-Gallwey scores could not be pooled for four studies comparing finasteride with flutamide as the results were inconsistent (I² = 67%).Studies examining effects of hypocaloric diets reported reductions in BMI, but which did not result in reductions in Ferriman-Gallwey scores. Although certain cosmetic measures are commonly used, we did not identify any relevant RCTs. AUTHORS' CONCLUSIONS Treatments may need to incorporate pharmacological therapies, cosmetic procedures, and psychological support. For mild hirsutism there is evidence of limited quality that OCPs are effective. Flutamide 250 mg twice daily and spironolactone 100 mg daily appeared to be effective and safe, albeit the evidence was low to very low quality. Finasteride 5 mg daily showed inconsistent results in different comparisons, therefore no firm conclusions can be made. As the side effects of antiandrogens and finasteride are well known, these should be accounted for in any clinical decision-making. There was low quality evidence that metformin was ineffective for hirsutism and although GnRH analogues showed inconsistent results in reducing hirsutism they do have significant side effects.Further research should consist of well-designed, rigorously reported, head-to-head trials examining OCPs combined with antiandrogens or 5α-reductase inhibitor against OCP monotherapy, as well as the different antiandrogens and 5α-reductase inhibitors against each other. Outcomes should be based on standardised scales of participants' assessment of treatment efficacy, with a greater emphasis on change in quality of life as a result of treatment.

Abstract
BACKGROUND Hirsutism has a relatively high prevalence among women. Depending upon societal and ethnic norms, it can cause significant psychosocial distress. Importantly, hirsutism may be associated with underlying disorders and co-morbidities. Hirsutism should not simply be looked upon as an issue of cosmesis. Patients require appropriate evaluation so that underlying etiologies and associated sequelae are recognized and managed. Treatment of hirsutism often requires a multidisciplinary approach, and a variety of physical or pharmacologic modalities can be employed. Efficacy of these therapies is varied and depends, among other things, upon patient factors including the underlying etiology, hormonal drive, and local tissue sensitivity to androgens. OBJECTIVE The objective of this paper is to review and summarize current evidence evaluating the efficacy of various treatment modalities for hirsutism in premenopausal women. METHODS Online databases were searched to identify all relevant prior systematic reviews and meta-analyses as well as recently published (2012-present) randomized controlled trials (RCTs) on hirsutism treatment. RESULTS Four recently published RCTs met criteria for inclusion in our review. In addition, one meta-analysis and one systematic review/treatment guideline were identified in the recent literature. Physical modalities and oral contraceptive pills (OCPs) remain first-line treatments. Evidence supports the use of electrolysis for permanent hair removal in localized areas and lasers (particularly alexandrite and diode lasers) for permanent hair reduction. Topical eflornithine can be used as monotherapy for mild hirsutism and as an adjunct therapy with lasers or pharmacotherapy in more severe cases. Combined OCPs as a class are superior to placebo; however, antiandrogenic and low-dose neutral OCPs may be slightly more efficacious in improving hirsutism compared with other types of OCPs. Antiandrogens are indicated for moderate to severe hirsutism, with spironolactone being the first-line antiandrogen and finasteride and cyproterone acetate being second-line antiandrogens. Due to its risk for hepatotoxicity, flutamide is not considered a first-line therapy. If used, the lowest effective dose should be administered with careful monitoring of liver enzymes. Monotherapy with an insulin sensitizer does not significantly improve hirsutism. While insulin sensitizers improve important metabolic and endocrine aberrations in polycystic ovary syndrome, they are not recommended when hirsutism is the sole indication for use. Lifestyle modification counseling is recommended. Gonadotropin-releasing hormone analogs and glucocorticoids are only recommended in specific circumstances. Additional therapies without sufficient supportive evidence of efficacy are ovarian surgery, statins (HMG-CoA reductase inhibitors), and vitamin D supplementation. LIMITATIONS In general, most therapies garner recommendations that are weak (where the estimates of benefits versus risks of therapy are either closely balanced or uncertain) and are based on low- to moderate-quality evidence. CONCLUSIONS Risks and benefits of treatment must be carefully considered and discussed with the patient. Expectations for efficacy should be appropriately set. A minimum of 6 months is required to see benefit from pharmacotherapy and lifelong treatment is often necessary for sustained benefit.

Abstract
Excessive hair growth in women is common and due to a broad spectrum of causes. Management options comprise different pharmaceuticals, epilation methods, and aesthetic approaches. Because excessive hair growth in women may cause psychological and psychosocial problems, a holistic treatment approach, including support and emotional coping strategies, should be recommended. In this article, diagnostic procedures and treatment options for excessive hair growth in female patients are discussed.

Abstract
Hirsutism is a common clinical condition seen in female patients of all ages. It affects around 5-10% of the women and is a common presenting complaint in the dermatological out patient department for cosmetic reasons. The cause is mainly hyperandrogeneism, which may be ovarian or adrenal. It may be part of a rare metabolic syndrome, drug induced, or just idiopathic. Hirsutism has a huge psychosocial impact, especially in the young females. This article reviews the current evaluation guidelines and management of hirsutism.

Abstract
BACKGROUND Hirsutism is the presence of excessive hair growth in women and is an important cosmetic condition often resulting in severe distress. The most common cause is by increased production of male sex hormones (androgens). It is also affected by increased sensitivity to androgens in the hair follicles, and secretory glands around hair follicles (sebaceous glands). Spironolactone is an antiandrogen and aldosterone antagonist used to treat hirsutism. OBJECTIVES The objective was to investigate the effectiveness of spironolactone and/or in combination with steroids (oral contraceptive pill included) in reducing excess hair growth and/or acne in women. SEARCH STRATEGY The Cochrane Menstrual Disorders and Subfertility Group (MDSG) trials register was searched (April 2008). The Cochrane MDSG register is based on regular searches of MEDLINE, EMBASE, CINAHL, PsycINFO and CENTRAL, handsearching of 20 relevant journals and conference proceedings, and searches of several key grey literature sources. In addition, all reference lists of relevant trials were searched and drug companies contacted for details of unpublished trials. SELECTION CRITERIA All randomised controlled comparisons of spironolactone versus: placebo, steroids (oral contraceptive pill included), spironolactone of varying dosages, or spironolactone and steroids versus steroids alone when used to reduce hair growth and acne in women. DATA COLLECTION AND ANALYSIS Nine trials were included in the review, eight trials were excluded. Two other trials are awaiting assessment. Only one trial studied acne as an outcome, the remainder were concerned with hirsutism. Major outcome measures include the following: subjective observations, Ferriman and Gallwey hair scores, hormonal and biochemical parameters, side effects, sebum production measurement. MAIN RESULTS In the two trials that compared 100 mg of spironolactone with placebo significant differences were reported for subjective improvements in hair growth (OR 7.18, 95% CI 1.96 to 26.28), although not the Ferriman-Galwey score (WMD 7.20, 95% CI -10.98 to -3.42)). Data could not be otherwise pooled as only one trial reported an outcome. AUTHORS' CONCLUSIONS From the studies included in this review, there is some evidence to show that spironolactone is an effective treatment to decrease the degree of hirsutism but there was no evidence for effectiveness for the treatment of acne vulgaris. Studies in this area are scarce and small. Individual study data indicates some superiority of spironolactone over other drugs but results cannot be generalised.

Abstract
Polycystic ovary syndrome (PCOS) is a syndrome, which can be defined as a group of recognisable patterns of symptoms or abnormalities that indicate a particular medical situation. The current definition of PCOS requires the presence of two of the following three conditions: (i) oligo- and/or anovulation; (ii) clinical and/or biochemical signs of hyperandrogenism; and (iii) polycystic ovaries--and the exclusion of other aetiologies. It is generally accepted that the prevalence of PCOS is approximately 5-10%, and that of polycystic ovaries alone is 21-23%. Other features of PCOS are obesity, insulin resistance, impaired glucose tolerance and type 2 diabetes mellitus, dyslipidaemia, cardiovascular disease, obstructive sleep apnoea and infertility. An approach to a patient with possible PCOS should be directed towards making a diagnosis and screening for associated endocrine abnormalities. Therapeutic interventions are directed towards addressing the needs of the patient at present and towards preventing long-term complications of the syndrome. Body mass index, which is a primary mediator in the relationship between PCOS and health-related quality of life in obese PCOS adolescents, may play a similar role in other PCOS patients. Any intervention directed at reducing central obesity will not only improve quality of life but also correct hyperinsulinism and improve fertility and lipid and androgen profiles. It is also the only currently available intervention that can have a lifelong impact on reducing possible long-term complications of the syndrome. Lifestyle modification is the cardinal intervention. Pharmacological treatments are available for specific indications. Infertility can be treated with clomifene (clomiphene citrate), metformin, gonadotropins or surgery to the ovaries. Cyproterone (alone or in combination with ethinylestradiol) and spironolactone are the main drugs used in the treatment of hirsutism. Other drugs that can be considered include flutamide, ketoconazole and finasteride. Women with PCOS require ongoing surveillance to detect impaired glucose tolerance, hyperlipidaemia, endometrial hyperplasia and consequent complications. Obese women, in particular, require regular glucose tolerance testing because of the potential for rapid progression from normal to impaired glucose tolerance and diabetes. The focus of this article is the epidemiology, diagnosis and management of this common endocrine disorder. Diagnostic and co-morbid features are discussed separately to facilitate understanding of PCOS. Symptom-directed strategies, as well as short- and long-term goals of treatment, are outlined.

Abstract
The pilosebaceous unit (PSU) response to androgen is variable. Certain population of PSU respond to androgen in a distinctive pattern that results in sexual hair development in some, sebaceous gland development in others. Furthermore, androgen excess is variably manifest in women as hirsutism, acne vulgaris, seborrhea, or pattern alopecia. Although sebaceous cells act as intracrine cells, activating pro-hormones to potent androgens that act within the sebocyte, hair follicle metabolism predominantly inactivates testosterone. Androgen action in the sexual hair follicle appears to be mediated by the dermal papilla and possibly, by inducing expression of a specific keratin, hHa7, in the hair medulla. The data do not clearly support a relationship between idiopathic hirsutism, the hirsutism that occurs in the absence of androgen excess, and variations in androgen mechanism of action. Androgens are prominent among the hormones that modulate the biological mechanism regulating the hair cycle. However, the basis for the variable pattern of PSU response to androgen is unclear, as is the basis for the variable development of hirsutism in response to androgen excess and the incomplete reversal of hirsutism by anti-androgen treatment. Improved treatment of hirsutism awaits improved understanding of the nature of the interaction between androgens and other determinants of hair follicle biology.

Abstract
BACKGROUND Women with polycystic ovarian syndrome (PCOS) commonly consult endocrinologists or gynaecologists and it is not known whether these specialty groups differ in their approach to management. OBJECTIVE To compare the investigation, diagnosis and treatment practices of endocrinologists and gynaecologists who treat PCOS. DESIGN AND SETTING A mailed questionnaire containing a hypothetical patient's case history with varying presentations--oligomenorrhoea, hirsutism, infertility and obesity--was sent to Australian clinical endocrinologists and gynaecologists in teaching hospitals and private practice. RESULTS Evaluable responses were obtained from 138 endocrinologists and 172 gynaecologists. The two specialty groups differed in their choice of essential diagnostic criteria and investigations. Endocrinologists regarded androgenization (81%) and menstrual irregularity (70%) as essential diagnostic criteria, whereas gynaecologists required polycystic ovaries (61%), androgenization (59%), menstrual irregularity (47%) and an elevated LH/FSH ratio (47%) (all P-values < 0.001). In investigation, gynaecologists were more likely to request ovarian ultrasound (91%vs. 44%, P < 0.001) and endocrinologists more likely to measure adrenal androgens (80%vs. 58%, P < 0.001) and lipids (67%vs. 34%, P < 0.001). Gynaecologists were less likely to assess glucose homeostasis but more likely to use a glucose tolerance test to do so. Diet and exercise were chosen by most respondents as first-line treatment for all presentations. However, endocrinologists were more likely to use insulin sensitizers, particularly metformin, for these indications. In particular, for infertility, endocrinologists favoured metformin treatment whereas gynaecologists recommended clomiphene. CONCLUSIONS There is a lack of consensus between endocrinologists and gynaecologists in the definition, diagnosis and treatment of PCOS. As a consequence, women may receive a different diagnosis or treatment depending on the type of specialist consulted.

Abstract
BACKGROUND Hirsutism is the presence of excessive hair growth in women and is an important cosmetic condition often resulting in severe distress. Hirsutism is most often caused by increased production of male sex hormones also known as androgens. It is also affected by increased sensitivity to androgens in the hair follicles, and the secretory glands around the hair follicles, called sebaceous glands. Spironolactone is an antiandrogen and aldosterone antagonist used to treat hirsutism. OBJECTIVES The objective of this review was to investigate the effectiveness of spironolactone and/or in combination with steroids (oral contraceptive pill included) in reducing excess hair growth and/or acne in women. SEARCH STRATEGY We searched the Cochrane Menstrual Disorders and Subfertility Group trials register (searched 12 June 2003). The Cochrane Menstrual Disorders and Subfertility Group register is based on regular searches of MEDLINE, EMBASE, CINAHL, PsycINFO and CENTRAL, the handsearching of 20 relevant journals and conference proceedings, and searches of several key grey literature sources. In addition, all reference lists of relevant trials were searched and drug companies contacted for details of unpublished trials. SELECTION CRITERIA All randomised controlled comparisons of spironolactone versus: placebo, steroids (oral contraceptive pill included), spironolactone of varying dosages, or spironolactone and steroids versus steroids alone when used to reduce hair growth and acne in women. DATA COLLECTION AND ANALYSIS Seven trials were included in the review, eight trials were excluded. Two other trials are awaiting assessment. All included trials were small (no more than 41 participants) randomised and controlled. Only one trial studied acne as an outcome, the remainder were concerned with hirsutism. Two trials investigated spironolactone versus placebo; one trial was a dosage studies of spironolactone; one trial compared spironolactone with spironolactone in combination with dexamethasone; one trial used topical spironolactone for the treatment of acne, one trial compared three treatments; spironolactone, finasteride, cyproterone acetate. Major outcome measures include the following: subjective observations, Ferriman and Gallwey hair scores, hormonal and biochemical parameters, side effects, sebum production measurement. MAIN RESULTS All sample populations were small and confidence intervals were wide. In the two trials that compared 100 mg of spironolactone with placebo significant differences were reported for subjective improvements in hair growth (OR 7.18, 95% CI 1.96 to 26.28), Ferriman-Galwey score (WMD 7.20, 95% CI -10.98 to -3.42)). The remaining comparisons were not statistically significant. There were statistically significant improvements in Ferriman-Galwey scores 12 months after the end of treatment in those women who received 100mg/day spironolactone compared to 12.5 mg/day cyproterone acetate (first 10 days of cycle) (WMD -1.18, 95% CI -2.1 to -0.26) and 5mg/day finasteride (WMD -2.34, 95% CI -3.23 to -1.45). REVIEWER'S CONCLUSIONS Six months treatment with 100 mg/day spironolactone compared with placebo was associated with a statistically significant subjective improvement in hair growth and a decrease in Ferriman-Galwey scores. Spironolactone 100mg/day is superior to finasteride 5 mg/day and low dose cyproterone acetate 12.5 mg/day (first 10 days of cycle) up to 12 months after the end of treatment. The effectiveness of treatment for acne vulgaris cannot be determined due to the small sample populations involved in the trials. Its value in clinical practice is difficult to assess from currently available research.
