Abstract
Congenital adrenal hyperplasias (CAH) are a group of autosomal recessive defects in cortisol biosynthesis. Substantial progress has been made since the description of the first report, 150 years ago. This article reviews some of the recent advances in the genetics, diagnosis and treatment of CAH. In addition, we underline the aspects where further progress is required, including, among others, better diagnostic modalities for the mild phenotype and for some of the rare forms of disease, elucidation of epigenetic factors that lead to different phenotypes in patients with identical genotype and expending on treatment options for controlling the adrenal androgen excess.

Abstract
Approximately 20-30% of PCOS women demonstrate excess adrenal precursor androgen (APA) production, primarily using DHEAS as a marker of APA in general and more specifically DHEA, synthesis. The role of APA excess in determining or causing PCOS is unclear, although observations in patients with inherited APA excess (e.g., patients with 21-hydroxylase deficient congenital classic or non-classic adrenal hyperplasia) demonstrate that APA excess can result in a PCOS-like phenotype. Inherited defects of the enzymes responsible for steroid biosynthesis, or defects in cortisol metabolism, account for only a very small fraction of women suffering from hyperandrogenism or APA excess. Rather, women with PCOS and APA excess appear to have a generalized exaggeration in adrenal steroidogenesis in response to ACTH stimulation, although they do not have an overt hypothalamic-pituitary-adrenal axis dysfunction. In general, extra-adrenal factors, including obesity, insulin and glucose levels, and ovarian secretions, play a limited role in the increased APA production observed in PCOS. Substantial heritabilities of APAs, particularly DHEAS, have been found in the general population and in women with PCOS; however, the handful of SNPs discovered to date account only for a small portion of the inheritance of these traits. Paradoxically, and as in men, elevated levels of DHEAS appear to be protective against cardiovascular risk in women, although the role of DHEAS in modulating this risk in women with PCOS remains unknown. In summary, the exact cause of APA excess in PCOS remains unclear, although it may reflect a generalized and inherited exaggeration in androgen biosynthesis of an inherited nature.

Abstract
Background Adrenal androgen excess is frequently observed in PCOS. The aim of the study was to determine whether adrenal gland function varies among PCOS phenotypes, women with hyperandrogenism (H) only and healthy women. Methods The study included 119 non-obese patients with PCOS (age: 22.2 ± 4.1y, BMI:22.5 ± 3.1 kg/m2), 24 women with H only and 39 age and BMI- matched controls. Among women with PCOS, 50 had H, oligo-anovulation (O), and polycystic ovaries (P) (PHO), 32 had O and H (OH), 23 had P and H (PH), and 14 had P and O (PO). Total testosterone (T), SHBG and DHEAS levels at basal and serum 17-hydroxprogesterone (17-OHP), androstenedione (A4), DHEA and cortisol levels after ACTH stimulation were measured. Results T, FAI and DHEAS, and basal and AUC values for 17-OHP and A4 were significantly and similarly higher in PCOS and H groups than controls (p < 0.05 for all) whereas three groups did not differ for basal or AUC values of DHEA and cortisol. Three hyperandrogenic subphenotypes (PHO, OH, and PH) compared to non-hyperandrogenic subphenotype (PO) had significantly and similarly higher T, FAI, DHEAS and AUC values for 17-OHP, A4 and DHEA (p < 0.05). All subphenotypes had similar basal and AUC values for cortisol. Conclusion PCOS patients and women with H only have similar and higher basal and stimulated adrenal androgen levels than controls. All three hyperandrogenic subphenotypes of PCOS exhibit similar and higher basal and stimulated adrenal androgen secretion patterns compared to non-hyperandrogenic subphenotype.

Abstract
OBJECTIVE To review all available data and recommend a definition for polycystic ovary syndrome (PCOS) based on published peer-reviewed data, whether already in use or not, to guide clinical diagnosis and future research. DESIGN Literature review and expert consensus. SETTING Professional society. PATIENTS None. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) A systematic review of the published peer-reviewed medical literature, by querying MEDLINE databases, to identify studies evaluating the epidemiology or phenotypic aspects of PCOS. RESULT(S) The Task Force drafted the initial report, following a consensus process via electronic communication, which was then reviewed and critiqued by the Androgen Excess and PCOS (AE-PCOS) Society AE-PCOS Board of Directors. No section was finalized until all members were satisfied with the contents, and minority opinions noted. Statements were not included that were not supported by peer-reviewed evidence. CONCLUSION(S) Based on the available data, it is the view of the AE-PCOS Society Task Force that PCOS should be defined by the presence of hyperandrogenism (clinical and/or biochemical), ovarian dysfunction (oligo-anovulation and/or polycystic ovaries), and the exclusion of related disorders. However, a minority considered the possibility that there may be forms of PCOS without overt evidence of hyperandrogenism, but recognized that more data are required before validating this supposition. Finally, the Task Force recognized and fully expects that the definition of this syndrome will evolve over time to incorporate new research findings.

Abstract
The polycystic ovary syndrome (PCOS) is a common disorder in premenopausal women, characterized by the presence, among other traits, of hyperandrogenism, insulin resistance, and hyperinsulinism. The familial aggregation of PCOS lead the interest to the molecular genetic basis of this syndrome, especially to the genes encoding proteins involved in androgen synthesis and the regulation of insulin synthesis and action. Considering the relationship between insulin resistance and chronic inflammation, and the clustering of inflammatory markers in PCOS patients, recent studies focused on the involvement of proinflammatory genotypes on the pathogenesis of PCOS. Mounting evidence suggest at present a complex model of inheritance for PCOS, in which predisposing and protecting genomic variants interact with environmental factors such as obesity and a sedentary lifestyle, finally leading to the classic phenotype of this syndrome. Moreover, the association of hyperandrogenism, insulin resistance and chronic inflammation raised the possibility of an increase risk of cardiovascular disease in women suffering from PCOS. In the present review we will summarize the most important findings published to date regarding the molecular genetic mechanisms underlying the association of PCOS with insulin resistance and chronic inflammation, and the possible interaction of these mechanisms with environmental factors.

Abstract
The purpose of this study was to determine if postmenopausal women with type 2 diabetes have clinical and biochemical evidence of androgen excess as a potential contributor to an increase in risk for coronary heart disease when compared with women without diabetes. Fasting glucose, insulin, lipids, sex hormone-binding globulin (SHBG), and sex steroids (from pooled samples) (total testosterone and free testosterone [non-SHBG-T], androstenedione [A-dione], total estrogens) were measured at baseline in 16 postmenopausal women with type 2 diabetes treated with diet or a sulfonylurea and 17 age-matched controls. Measurements of glucose, insulin, and sex steroids were repeated at hourly intervals for 3 hours after oral glucose administration. Hirsutism scores and insulin sensitivity (homeotasis model assessment [HOMA] insulin [SI]) were obtained. Women with type 2 diabetes were more hyperglycemic, hyperinsulinemic, and insulin-resistant (HOMA SI, 46.7 +/- 7.0 vs 12.9 +/- 2.0, P < .001), and had higher total to high-density lipoprotein cholesterol (TC/HDL) ratios, lower SHBG (20.8 +/- 3.5 vs 59.3 +/- 14.4 nmol/L, P < .05), higher non-SHBG-T (0.225 +/- 0.025 vs 0.135 +/- 0.021 nmol/L, P < .05), and higher hirsutism scores (1.1 +/- 0.3 vs 0.3 +/- 0.2, P = .004) than those without diabetes. No changes in sex steroids occurred after the oral glucose challenge. HOMA SI and area under the curve for glucose correlated significantly with SHBG (r = -0.42), non-SHBG-T (r = 0.40), and TC/HDL (r = 0.41) (all P < .05) in the combined groups. Postmenopausal women with type 2 diabetes have both clinical and biochemical evidence of androgen excess that may contribute to more adverse cardiovascular risk profiles.

Abstract
The genetic mechanisms underlying functional hyperandrogenism and the polycystic ovary syndrome (PCOS) remain largely unknown. Given the large number of genetic variants found in association with these disorders, the emerging picture is that of a complex multigenic trait in which environmental influences play an important role in the expression of the hyperandrogenic phenotype. Among others, genomic variants in genes related to the regulation of androgen biosynthesis and function, insulin resistance, and the metabolic syndrome, and proinflammatory genotypes may be involved in the genetic predisposition to functional hyperandrogenism and PCOS. The elucidation of the molecular genetic basis of these disorders has been burdened by the heterogeneity in the diagnostic criteria used to define PCOS, the limited sample size of the studies conducted to date, and the lack of precision in the identification of ethnic and environmental factors that trigger the development of hyperandrogenic disorders. Progress in this area requires adequately sized multicenter collaborative studies after standardization of the diagnostic criteria used to classify hyperandrogenic patients, in whom modifying environmental factors such as ethnicity, diet, and lifestyle are identified with precision. In addition to classic molecular genetic techniques such as linkage analysis in the form of a whole-genome scan and large case-control studies, promising genomic and proteomic approaches will be paramount to our understanding of the pathogenesis of functional hyperandrogenism and PCOS, allowing a more precise prevention, diagnosis, and treatment of these prevalent disorders.

Abstract
Congenital adrenal hyperplasia due to 3beta-hydroxysteroid dehydrogenase/Delta(5)-Delta(4)-isomerase (3betaHSD), a rare autosomal recessive disorder that affects both sexes, has a heterogeneous clinical presentation ranging from the severe salt-wasting to the non-salt-wasting forms and results from mutations in the HSD3B2 gene. The hormonal criteria for diagnosing the mild variant of 3betaHSD deficiency have been controversial because the initial studies were not based on genetic evidence. We investigated the relationship between the hormonal phenotype and HSD3B2 genotype in 22 patients with clinical and/or biochemical features suggestive of 3betaHSD2 deficiency, including nine female children with premature pubarche, 12 hirsute females, and one boy with salt-wasting and ambiguous genitalia. Serum 17-hydroxypregnenolone (Delta5-17P), cortisol (F), 17-hydroxyprogesterone, dehydroepiandrosterone, and androstenedione levels were determined by RIA and were compared with Tanner pubic hair stage-matched control groups. The genomic DNA was extracted, and the entire HSD3B2 gene was amplified by PCR followed by automatic sequencing. Besides two different mutations previously observed in three patients (T259M and G129R/P222Q mutations), we observed the P222Q mutation in the male patient with salt-wasting form of 3betaHSD2 deficiency. Basal and ACTH-stimulated Delta5-17P levels (nanomoles per liter) ranged from 4-41 (-0.2 to 14 sd) and 36-97 (3.5-15.5 sd), respectively, in patients without mutation in HSD3B2 and from 69-153 (25-57 sd) and 201-351 (36-65 sd), respectively, in patients with mutation in HSD3B2. Basal and ACTH-stimulated Delta5-17P to F ratios ranged from 11-159 (0.5-25 sd) and 42-122 (2.4-11.3 sd), respectively, in patients without mutation in HSD3B2 and from 181-1700 (29-282 sd) and 487-1523 (52-167 sd), respectively, in patients with mutation in HSD3B2. The hormone findings in the genotype-proven patients suggest that the following hormonal criteria are compatible with 3betaHSD2 deficiency in children with premature pubarche: ACTH-stimulated Delta5-17P and Delta5-17P to F ratios at or greater than 201 and 487 nmol/liter, respectively, equivalent to or greater than 36 and 52 sd above matched control mean. Basal and ACTH-stimulated Delta5-17P and Delta5-17P to F ratios in all genotype-proven patients in childhood were unequivocally higher than the levels of either genotype-normal patients. All the other parameters overlapped between the patients with and without mutations in the HSD3B2 gene. In conclusion, genotyping more patients in the present study, we confirm that patients with mutations in the HSD3B2 gene have extremely elevated basal and ACTH-stimulated Delta5-17P levels and Delta5-17P to F ratios. Therefore, these data refine the hormonal criteria proposed to predict more accurately 3betaHSD2 deficiency.

Abstract
Late onset congenital adrenal hyperplasia (LO CAH) can be seen in association with polycystic ovary syndrome (PCOS) or idiopathic hirsutism (IH). The study aimed to find out the prevalence of LO CAH in Central Anatolia among hirsute women. Sixty-three patients with hirsutism were evaluated to determine the frequency of LO CAH by comparing them with their age and body mass index matched 28 healthy controls. Of those 63 hirsute women, 43 were diagnosed as PCOS, and 20 were diagnosed as IH. Following basal hormonal evaluation, all subjects underwent ACTH stimulation test and ACTH stimulated 17-hydroxyprogesterone (17-OH P), 11-desoxycortisol (11-DOC), cortisol (F), and dehydroepiandrosterone sulfate (DHEA-S) levels were determined in all subjects. ACTH stimulated 17-OH P, 11-DOC, and DHEA-S levels did not differ between groups. However, stimulated F levels were found to be higher in hirsute women (p<0.001). Six out of 63 (9.52%) patients with hirsutism met the criterion for 21 hydroxylase deficiency. We found no subject presumed to have 11-beta hydroxylase deficiency, but one subject in control group (3.57%) and two patients among PCOS subjects (4.65%) had exaggerated DHEA-S response which was suggestive of mild 3-beta hydroxysteroid dehydrogenase deficiency. In conclusion, the most frequent form of LO CAH seems to be due to 21 OH deficiency among women with PCOS and IH in Central Anatolia. Mild 3-beta HSD deficiency may also be an underlying cause for hirsutism and it may be seen without any clinical presentation. Adrenal hyperactivity is likely to be the main reason of hyperandrogenemia in women with hirsutism.

Abstract
Polycystic ovary syndrome is a heterogeneous clinical syndrome, which has been defined as the association of hyperandrogenism with chronic anovulation in women without specific adrenal and pituitary gland disease. A family history of polycystic ovary syndrome may be present in a subset of patients; however, the genetic basis of the syndrome remains unclear. Most often, the age of onset is perimenarchal and it is characterized by the appearance of menstrual disturbances, hirsutism, acne, and more rarely, a male pattern of alopecia. In some cases, premature adrenarche may present as a precursor to the development of the syndrome. Polycystic ovary syndrome is also associated with metabolic disturbances, such as obesity and insulin resistance with hyperinsulinemia, for which the pathophysiological role in the development of the syndrome has been recognized. The therapeutic approaches to polycystic ovary syndrome include lifestyle modifications, dietary-induced weight loss, insulin-sensitizing agents, antiandrogens, and oral contraceptives. These treatments may improve the clinical manifestations of excess androgen production and normalize menses in many adolescents and young women with polycystic ovary syndrome. Early recognition of the syndrome and thus, early treatment, may prevent and possibly ameliorate all the symptoms and the potential later development of metabolic and cardiovascular complications.

Abstract
Adrenal androgen excess affects approximately 25% of PCOS patients. The exact etiology of this excess in PCOS patients is unclear. Some evidence that adrenal androgen excess may be a genetic trait. The adrenal androgen response to ACTH is highly individualized, and the relative response seems to be constant over time. In addition, there is a strong familial component to adrenal androgen levels in normal individuals and PCOS patients. It is possible that the tendency to overproduce adrenal androgens is an inherited risk factor for the development of PCOS. Overall, few hyperandrogenic patients actually have isolated deficiencies of 3 beta-hydroxysteroid dehydrogenase, 21-hydroxylase, and 11-hydroxylase. The ovarian hormonal secretion in PCOS can affect adrenal androgen secretion and metabolism, although this factor accounts for only part of this abnormality. More likely, the adrenal androgen excess results from a generalized hyperresponsiveness of the adrenal cortex to ACTH, but without an increase in CRH or ACTH sensitivity. Although glucocorticoid administration may improve the ovulatory function of these patients, the results are modest and cannot be predicted by the circulating androgen levels.

Abstract
OBJECTIVE To determine the role of heterozygosity for mutations in the 21-hydroxylase gene (CYP21) in the pathogenesis of hyperandrogenism. DESIGN Controlled clinical study. SETTING Tertiary care institutional hospital. PATIENT(S) Forty hirsute women and 13 healthy control women. INTERVENTION(S) The source of androgen excess was determined by the changes in serum testosterone levels in response to a single 3.75-mg i.m. dose of triptorelin. MAIN OUTCOME MEASURE(S) CYP21 molecular genetic analysis and serum 17-hydroxyprogesterone levels. RESULT(S) Eight patients and one control were heterozygous carriers of CYP21 mutations. Two patients with adrenal hyperandrogenism and one patient with ovarian hyperandrogenism, who carried the V281L mutation had an increased ACTH-stimulated 17-hydroxyprogesterone level (>4.1 ng/mL) that persisted during gonadal suppression. Another patient with adrenal hyperandrogenism carried the V281L mutation, and her ACTH-stimulated 17-hydroxyprogesterone level was elevated only during gonadal suppression. Four patients (three with idiopathic hirsutism, one with ovarian hyperandrogenism) and one control were carriers of CYP21 mutations typically associated with classic congenital adrenal hyperplasia but had normal basal and ACTH-stimulated 17-hydroxyprogesterone levels. Nine patients without CYP21 mutations had increased ACTH-stimulated 17-hydroxyprogesterone levels; these decreased to normal in six of the patients during gonadal suppression. CONCLUSION(S) The response of serum 17-hydroxyprogesterone to ACTH does not predict CYP21 carrier status. No clear concordance was found between the CYP21 genotype and the functional origin of androgen excess.

Abstract
OBJECTIVE We sought to determine the prevalence of 3beta-hydroxysteroid dehydrogenase-deficient nonclassic adrenal hyperplasia among adult hyperandrogenic women with dehydroepiandrosterone sulfate excess. STUDY DESIGN Thirty consecutive hyperandrogenic women with hirsutism, oligomenorrhea, or both and dehydroepiandrosterone sulfate levels of >8.5 micromol/L and 24 control subjects were studied. Basal sex hormone binding globulin, total and free testosterone, dehydroepiandrosterone sulfate, 17-hydroxyprogesterone, and basal and 60-minute corticotropin-stimulated 17-hydroxypregnenolone and dehydroepiandrosterone were measured, and the increment (change from basal to 60-minute value) was calculated. RESULTS Twenty-six (87%) and 25 (83%) of the 30 hyperandrogenic patients studied had 60-minute dehydroepiandrosterone and change in 0- to 60-minute dehydroepiandrosterone levels greater than the mean + 2 SD of control subjects, respectively. Six (20%) and 6 (20%) of the 30 hyperandrogenic patients had 60-minute 17-hydroxypregnenolone and 0- to 60-minute change in 17-hydroxypregnenolone levels greater than the mean + 2 SD of control subjects, respectively. However, none of the subjects had either 60-minute 17-hydroxypregnenolone levels or 60-minute dehydroepiandrosterone levels or both associated with the diagnosis of genetically proved 3beta-hydroxysteroid dehydrogenase deficiency (>5-fold of the control mean value). CONCLUSION 3beta-Hydroxysteroid dehydrogenase-deficient nonclassic adrenal hyperplasia is rare even among adult hyperandrogenic patients with adrenal androgen excess.

Abstract
Androgens are secreted by both the ovaries and adrenal glands in response to their respective trophic hormones LH and ACTH. Androgens in women are not specifically under negative feedback control by these pituitary hormones because they are by-products of estradiol and cortisol secretion. Rather, androgen secretion seems to be regulated mostly by intraglandular mechanisms. Functional ovarian hyperandrogenism is found in about 70% of patients with PCOS. It is characterized by excessive secretion of 17-hydroxyprogesterone in response to GnRH agonist or hCG stimulation. Failure of dexamethasone to suppress plasma free testosterone normally in the presence of normal adrenocortical suppression is also typical. Functional adrenal hyperandrogenism is found in about half of patients with PCOS. It is most often characterized by moderately increased secretion of the 17-ketosteroid DHEA in response to ACTH. The most likely cause of the excessive androgen secretion by both glands seems to be abnormal regulation (dysregulation) of the 17-hydroxylase and 17,20-lyase activities of P-450c17, the rate-limiting step in androgen biosynthesis. There are also subtle generalized disturbances of steroid metabolism, including tendencies toward excessive estrogen and cortisol secretion. The cause of dysregulation of steroidogenesis is unknown. The hyperinsulinemia that is compensatory for resistance to the glucose-metabolic effect of insulin seems to have a role in many cases. In most cases, intrinsic intraovarian or intra-adrenal autocrine or paracrine regulatory mechanisms are most likely malfunctioning.

Abstract
Adrenal function may be abnormal in women with polycystic ovary syndrome (PCOS). This study aims to evaluate adrenal steroid response to the adrenocorticotropic hormone (ACTH) stimulation test and to find out the effect of high serum testosterone levels on adrenal response. We have also investigated any subtle enzyme deficiency by extending blood sampling to 2 h with 30 min intervals following ACTH administration. Twenty-eight women with PCOS and 18 healthy controls without hirsutism and oligomenorrhea were included in the study. After determining their serum basal levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, dehydroepiandrosterone sulfate (DHEAS), 17-hydroxyprogesterone (17-OHP), and progesterone, ACTH stimulation test was performed. The change in serum 17-OHP and the summed rate of change in serum 17-OHP and progesterone levels were estimated and 95th percentile for each value was computed. Women with PCOS were heavier and more hirsute than controls (p < 0.01, p < 0.001, respectively). Serum basal LH, LH:FSH ratio, testosterone (p < 0.001, for all), DHEAS (p < 0.01), and 17-OHP (p < 0.05) were higher in women with PCOS. All of the 17-OHP measurements, including basal and each 30 min interval after the administration of ACTH, were higher in women with PCOS than those of healthy controls (p < 0.05, p < 0.002, p < 0.001, p < 0.015, p < 0.018, respectively). However, the incremental changes in serum 17-OHP30-0, 17-OHP60-0, 17-OHP90-0, 17-OHP120-0, and the summed rate of change in serum 17-OHP and progesterone in women with PCOS were not different from those in healthy controls. The incremental response in terms of serum progesterone, DHEAS, and testosterone levels to the ACTH stimulation test for each 30 min interval was not different in women with PCOS than in healthy controls. We were not able to show any critical value for serum basal testosterone and DHEAS levels that would effect response to ACTH stimulation in terms of 17-OHP levels. We have concluded that extending the duration of blood sampling up to 2 h has no advantage in evaluating adrenal steroid response to ACTH stimulation. Since serum 17-OHP levels remain within normal limits in response to ACTH stimulation, the origin of elevated serum basal 17-OHP levels may be polycystic ovaries. Elevated serum testosterone level does not have any adverse effect on adrenal function. Serum progesterone measurement seems to have no place in the diagnosis of 21-hydroxylase deficiency. Adrenal androgenic response to ACTH stimulation is normal in women with PCOS.

Abstract
To ascertain the potential role of heterozygosity for 3beta-hydroxysteroid (3beta-HSD) deficiency in children with premature pubic hair and adolescent girls with hyperandrogenism, we performed single-strand conformational polymorphism (SSCP) analysis of the 3beta-hydroxysteroid dehydrogenase type 2 (3beta-HSD2) gene in 34 hyperandrogenic patients. Three sequence variants, two missense mutations and a 3'-UTR sequence variant, were detected among seven patients and in none of 100 healthy control subjects. One of these seven patients carried Leu236 --> Ser on one 3beta-HSD2 allele and Glu318 --> STOP on one 21-hydroxylase (CYP21) allele. ACTH stimulation tests were performed in 5/7 patients with sequence variants and were compatible with decreased 3beta-hydroxysteroid dehydrogenase activity in three. Thus, 7 of 34 (20.6%) mildly hyperandrogenic patients carry heterozygous sequence variants of the 3beta-HSD2 gene. Since obligate heterozygotic carriers for congenital adrenal hyperplasia are typically asymptomatic, other genetic or environmental influences may contribute to the expression of hyperandrogenic symptoms in our patients.

Abstract
STUDY OBJECTIVE To determine whether human chorionic gonadotropin (hCG) stimulation elicits an exaggerated 17-hydroxyprogesterone (17-OHP) response in patients with functional ovarian hyperandrogenism. METHODS In this clinical study, healthy volunteers and hyperandrogenic patients in an outpatient General Clinical Research Center (GCRC) setting were studied. Five adolescent girls with functional ovarian hyperandrogenism were studied. Six healthy women with regular menstrual cycles volunteered for this study. Steroid hormone responses to hCG stimulation were measured before and 30, 240, and 300 minutes after hCG injection. Congenital adrenal hyperplasia was excluded through ACTH stimulation testing and molecular genetic analysis. MAIN OUTCOME MEASURE 17-OHP responses. RESULTS Mean basal 17-OHP concentrations were greater in the hyperandrogenic patients, 110.4+/-41.2 ng/dL versus 61.8+/-28.6 ng/dL. After hCG stimulation, 17-hydroxyprogesterone concentrations significantly increased in the patients and were unchanged in the healthy controls. CONCLUSION hCG stimulation elicited greater 17-hydroxyprogesterone responses in adolescent girls with functional ovarian hyperandrogenism compared with healthy controls. hCG stimulation may be helpful to confirm ovarian hyperandrogenism.

Abstract
The purpose of this prospective study was to determine the incidence of any form of 21 alpha-hydroxylase deficiency among Greek women with hyperandrogenic symptoms, and to test the predictive value of basal serum 17-hydroxyprogesterone (17-OHP) in the early follicular phase as a screening index for patient preselection to adrenocorticotropic hormone (ACTH) testing. Eighty-eight unselected women with hyperandrogenic symptoms were examined in the Gynecological Endocrinology Unit of the Second Department of Obstetrics and Gynecology of Athens University. Using the ACTH-stimulated 17-OHP values at 60 minutes (17-OHP60) the study population was divided into four groups (A, B, C and D). Clinical and basal hormonal parameters as well as serum 17-OHP60 values and human leukocyte antigens were studied. Both clinical and basal hormonal parameters could be used to distinguish only patients with severe 21 alpha-hydroxylase deficiency (group A). In contrast, patients with moderate non-classical congenital adrenal hyperplasia (NC-CAH; group B), heterozygotes for NC-CAH (group C), and unaffected females (group D) can be diagnosed and classified only by serum 17-OHP60 values. In conclusion, the incidence of NC-CAH in Greek females with hyperandrogenic symptoms is 3.4%. The positive predictive value of basal 17-OHP is only 13% for this disease. Only 17-OHP60 helps to diagnose and classify moderate and mild forms of NC-CAH. Thus, it seems that ACTH testing is imperative in every subject suspected of this enzymatic disorder.

Abstract
Severe 3beta-hydroxysteroid dehydrogenase (3beta-HSD) deficiency in the adrenals and gonads is a well known cause of salt-wasting and non-salt-wasting forms of congenital adrenal hyperplasia (CAH), male pseudohermaphroditism and mild androgen excess symptoms in children and older females. A mild spectrum of Delta5 steroid abnormality in young children with premature pubarche and older females with hirsutism and menstrual disorder was presumed to be due to a mild variant of 3beta-HSD deficiency CAH. Recent studies of the type II 3beta-HSD gene encoding adrenal and gonadal 3beta-HSD have indicated that only the severe 3beta-HSD deficiency CAH results from a deleterious mutation in the gene. This indicates that the mild Delta5 steroid abnormality is not due to a variant of 3beta-HSD deficiency CAH. The hormonal criteria for bona fide mild variants of 3beta-HSD deficiency and etiology of mild Delta5 steroid abnormality in the patients remain to be investigated.

Abstract
Carney syndrome is a rare, autosomal dominant, multi-system disorder comprising 8 well-characterized findings, only 2 of which need be present for a definitive diagnosis. Benign neoplasms are frequent, but malignancies are thought to be uncommon. We have studied a family to clarify the diagnosis and spectrum of clinical manifestations of the syndrome and to develop guidelines for management. The proposita, a 34-year-old woman had classic findings of Carney syndrome, invasive follicular carcinoma of the thyroid gland, Barrett metaplasia of the esophagus, neoplastic colonic polyps, bipolar affective disorder, and atypical mesenchymal neoplasm of the uterine cervix distinct from the myxoid uterine leiomyoma usually seen in this syndrome. Although thyroid gland neoplasm is rare in Carney syndrome, this patient's most aggressive manifestation was her thyroid carcinoma. The diagnosis of Carney syndrome was established in her 9-year-old son and is a probable diagnosis in her 12-year-old daughter. Endocrine manifestations were prominent in the family with at least 9 relatives in 3 generations affected with various endocrine abnormalities. The findings in this family indicate that the spectrum of manifestations in this pleiotropic gene apparently includes a malignant course with premalignant and endocrinologic disorders not previously recognized.

Abstract
Cogenital adrenal hyperplasia (CAH) is a family of genetic disorders from a deleterious mutation in a gene encoding adrenal steroidogenic enzyme essential for cortisol biosynthesis. Recent molecular advances have provided the genetic basis for the phenotypic variability in CAH, a means for accurately genotyping family members of CAH patients including prenatal prediction of the genotype in fetuses at risk of the disorder, and have helped to better define the hormonal criteria for the varying spectrum of CAH disorders. Biochemical advances have simultaneously aided the diagnosis and therapeutic monitoring of CAH patients. Prenatal maternal dexamethasone therapy for fetal CAH prevents or minimizes virilizing sequelae in the majority of prenatally treated affected females, but was associated with significant maternal side effects. Newborn screening for CAH has contributed to the prevention of morbidity of delayed diagnosis of CAH in more than two third of affected neonates. Current treatment methods, however, may not be optimal for achieving normal genetic height and appropriate weight in CAH patients, and more effective approaches to CAH therapy remain to be explored.

Abstract
OBJECTIVE To investigate the presence of a dysregulation in steroid biosynthesis in women from southern Italy. DESIGN Controlled clinical study. SETTING Normal and hyperandrogenic women referred to the Endocrinology Unit of Federico II University Medical School of Naples. PATIENT(S) One hundred fifty untreated young hyperandrogenic women and 50 normal age-matched women. INTERVENTION(S) Morning (basal) blood samples obtained in the early follicular phase and after a long (360 minute) ACTH stimulation test. MAIN OUTCOME MEASURE(S) The adrenal maximal response was calculated as stimulus under curve areas (AUCa), and all steroids were assayed using RIA methods. RESULT(S) A dysregulation of 21-hydroxylase was found in 22 patients (14.7%), with a prevalent increase of 17 alpha-hydroxyprogesterone AUC, whereas in 9 hirsute women (6%), there was a prevalent significant increase in 11-deoxycortisol AUC. In 5 women (3.3%), DHEA and DHEAS basal and AUCs plasma levels were increased, suggesting an impaired 3 beta-olo-dehydrogenase activity. The remaining 114 hyperandrogenic women (76%) compose the nonadrenal group, with a probable diagnosis of primitive functional ovarian hyperandrogenism. CONCLUSION(S) Considering the high prevalence of hirsutism and oligomenorrhea in our female hyperandrogenic population, we suggest an adrenal hyperresponsiveness likely due to a dysregulation in enzymes related to androgen adrenal steroidogenesis.

Abstract
In an effort to elucidate the aetiology of female-to-male transsexualism (FM-TS) 12 out of an annual sample of 16 untreated female-to-male transsexuals (FMT), aged 19 years 7 months (19;7) to 44 years 8 months (44;8) [median age (M) 27;5] were assessed by means of sexual-medical questionnaires, physical and endocrinological examination. The control group consisted of 15 healthy women (CF), aged 19 years 2 months (19;2) to 36 years 1 month (36;1) (M 22;7) without gender identity disorder, who were not under hormonal medication (including contraceptives). Baseline levels of testosterone (T; ng/dl), androstenedione (A4; ng/dl), dehydroepiandrosterone sulfate (DHEAS; ng/ml), luteinizing hormone (LH; IU/l), follicle stimulating hormone (FSH; IU/l), and sex-hormone binding globuline (SHBG; microgram/dl) were measured. A standard single-dose ACTH stimulation test (250 micrograms ACTH IV; Synacthen) was performed with all subjects. Aldosterone (ALDO), corticosterone (B), deoxycorticosterone (DOC), progesterone (PROG), 17-hydroxyprogesterone (17OHP), 11-deoxycortisol (S), cortisol (F), cortisone (E), pregnenolone (PREG) and 17-hydroxypregnenolone (OHPREG) were assessed before and 60 min after ACTH stimulation. Transvaginal ultrasound was performed in nine out of 12 FMT (20;11 to 44;8, M 27;5; m 29.1 +/- 7.5) but not in CF. Results showed that 10 FMT (83.3%) and five CF (33.3%) were above normal values for at least one of the measured androgens. Baseline levels of T and A4 were significantly higher in FMT than in CF (T: 54.0 +/- 13.8 vs. 41.1 +/- 12.8; A4: 244.8 +/- 73.0 vs. 190.5 +/- 49.3; p < .05), whereas DHEAS, SHBG, LH and FSH did not differ between the groups. Unbound T (T/SHBG ratio) was higher in FMT (72.0 +/- 67.6) than in CF (26.4 +/- 15.1). Baseline levels of 17OHP, OHPREG and DOC were higher in FMT than in CF (p < .05). After ACTH stimulation 17OHP and OHPREG remained higher in FMT than in CF (p < .05). Single case analysis of ACTH stimulation test together with physical examination revealed symptoms for non-classical congenital adrenal hyperplasia (NC-CAH) in six FMT (50%) and two CF (13.3%). Eight out of nine FMT who were assessed by means of transvaginal ultrasound (i.e. 88.9%; 50.0% of 16) had polycystic ovaries (PCO). Oligomenorrhoea or menstrual dysregularities (81.7% of 16 FMT vs. 0% of CF), hirsutism (56.2% of 16 FMT vs. 13.3% of 15 CF) and adiposity (25.0% vs. 0%) were frequent in FMT, but not in CF. Hyperandrogenism with polycystic ovarian syndrome (PCOS) and adrenocortical hyperresponsiveness to ACTH seems to be a common finding in FMT. This offers support for a hormonal factor in the genesis of FM-TS. Because the prevalence of PCOS and NC-CAH in the female population is higher than FM-TS, the true nature of this factor and its interaction with environmental influences remains unknown.

Abstract
Diagnostic categories in hyperandrogenism include polycystic ovary syndrome (PCOS) and its variants, adrenal and ovarian steroidogenic enzyme deficiencies, adrenal and ovarian androgen secreting tumours and other endocrine disorders such as hyperprolactinaemia, Cushing syndrome and acromegaly. About 95% of hyperandrogenic women will have PCOS. Endometrial hyperplasia can be prevented in hyperandrogenic, anovulatory women by the oral contraceptive pill or progestins. Hirsutism is best treated by a combination of the oral contraceptive pill and an anti-androgen. The first line of therapy for ovulation induction is clomiphene citrate, with human menopausal gonadotrophins (hMG) or laparoscopic ovulation induction reserved for clomiphene failures. hMG together with gonadotrophin-releasing hormone agonist may decrease the risk of spontaneous abortion following ovulation induction in PCOS. Weight loss should be vigorously encouraged to ameliorate the metabolic consequences of PCOS.

Abstract
Solvent inhalation is a well-documented form of drug abuse that can cause euphoria and hallucinations. Sudden death involving a volatile substance is most commonly caused by cardiac arrythmias, asphyxia, direct drug effects, and trauma. The victim in this paper suffered superficial partial thickness (12% total body surface area) burns from a flash fire that occurred when lighting a match after inhaling butane in an enclosed vehicle. The victim was admitted to the hospital for 2 days of observation but did not develop any respiratory symptoms under 2 days following her release. The victim died during her readmission, 9 days after the flash fire. Postmortem examination showed extensive epithelial injury from the upper airway and trachea to the terminal bronchioles, most likely due in part to both the initial inhalation injury and the resulting adult respiratory distress syndrome (ARDS) and staphylococcal infection. Many victims with superficial burn injuries may not seek medical attention owing to either embarrassment or fear of legal prosecution. Even those who do seek medical assistance may not reveal solvent abuse as the cause of their injuries. It is possible that delayed death may occur at home following volatile substance abuse but may remain unrecognized even with a thorough scene investigation.

Abstract
A clinical spectrum, varying from prenatal onset to postnatal onset of symptoms, exists in all hyperandrogenic forms of congenital adrenal hyperplasia (CAH). Postnatal onset hyperandrogenic symptoms such as premature pubarche, clitoromegaly, hirsutism, menstrual disorders and infertility are well known manifestations of CAH due to 21-hydroxylase deficiency, 3 beta-hydroxysteroid dehydrogenase deficiency or 11 beta-hydroxylase deficiency. These hyperandrogenic symptoms of CAH are clinically indistinguishable from other causes of hyperandrogenism. The molecular data has proven the genetic basis for the phenotypic variability of CAH disorders. Specific hormonal criterion(a) defined by the molecular proof of the disorder should aid in discriminating between symptomatic patients due to CAH and other causes, and between those with mild and severe CAH disorders. Prevalence of the hyperandrogenic forms of CAH, as well as pubertal maturation and reproductive function in women with hyperandrogenic forms of CAH, are discussed.

Abstract
It is now known that there are major differences in the systemic and cellular mechanisms that mediate hair loss in women versus men. The severity or degree of hair loss in women with androgenetic alopecia is usually much less than in men. It is usually assumed that the hormonal basis for androgenetic alopecia in women is the same as in men; that is, the same target tissue-active androgens, testosterone and dihydrotestosterone, are being produced systemically to aggravate scalp hair follicles, resulting in hair loss. This article reviews some of the latest findings in androgenetic alopecia for both men and women, along with new and old treatments and drugs, doses, and effectiveness. Research findings indicate that levels of androgen-metabolizing enzymes and receptors differ in the scalps of women versus men, which may be important in formulating more effective hair growth treatments in the future.

Abstract
OBJECTIVE To evaluate ovarian and adrenal steroid secretion in women with severe hyperandrogenism. DESIGN A prospective study. SETTING The Gynecological Endocrine Research Unit of the University Central Hospital, Oulu, Finland. PATIENTS Thirteen obese, hirsute women with severe hyperandrogenism. INTERVENTIONS Adrenocorticotropin hormone stimulation and dexamethasone suppression tests and selective catheterizations of the left ovarian and adrenal veins were performed. MAIN OUTCOME MEASURES The concentrations of insulin, P, 17-hydroxyprogesterone (17-OHP), androstenedione (A), T, DHEA, DHEAS, and cortisol were measured. RESULTS The secretory gradients of T and its precursors, P, 17-OHP, A, and DHEA in the selective catheterizations showed the adrenal to be the main source of excessive steroid production in these patients. The concentrations of P (r = 0.82), 17-OHP (r = 0.89), A (r = 0.84), T (r = 0.86), and cortisol (r = 0.87) in the adrenal vein showed a strong correlation with insulin measured from the same samples. CONCLUSIONS Excessive androgens were secreted mainly by the adrenals in these obese hyperinsulinemic women. Correlation analyses suggested that insulin stimulates adrenal androgen and cortisol secretion, which may constitute an important component of the pathogenetic mechanisms of hyperandrogenism and the polycystic ovary syndrome.

Abstract
The available evidence reviewed does not allow definitive response to the question of a primary versus secondary role of sex hormone perturbations in RA. However, this conclusion should not be discouraging in view of the relatively recent focus upon this facet of the physiopathogenesis of RA and the enormous complexities of sex hormone biology and this disease. Specifically, data on the incidence of RA as well as life cycle changes in serum androgenic-anabolic (A-A) and sex hormone levels suggest important risk correlations. Furthermore, HLA-susceptibility markers for RA, gender, menopause and older age are all factors which significantly relate to the risk of developing RA and each has been shown to associate with sex hormone status. Whether or not HPG-AA hormonal status may modulate RA risk (or its course) primarily and independently or merely be predictive markers of other biological mechanisms was critically considered and requires further study. Sex hormone influences on cellular and humoral immunological reactivity and vascular pathogenetic mechanisms in RA were summarized. Androgens generally suppress immunoreactivity and cartilage responses to inflammation-mediated injury processes and may enhance synovial macrophage-like lining cell apoptosis. Oestrogens generally enhance immunoreactivity, offer some protection to inflammation-mediated cartilage damage (but less than androgens) and may inhibit apoptosis in certain in vitro cell models. Scant information is available on the balance of sex hormones (and glucocorticoids) in RA or its presumed pathogenetic mechanisms. Data were reviewed which support the concept of a spectrum of androgenicity in the normal population, particularly among women. A simplified schema of trophic and tropic steroidogenic mechanisms was proposed which could influence androgenic-anabolic (A-A) status and might relate to RA. Serum concentrations of DHAS (mumol/l), T (nmol/l) and O2 (pmol/l) span several orders of magnitude in normal physiology. The effects of alterations in the individual levels of these sex hormones and deviations from their normal physiological balance are not well understood. Critical attention to their biological functions is needed in RA as well as in health and disease generally. Such focused clinical and experimental investigations of HPG-AA functions promise to clarify the complex physiopathology of RA and contribute to its improved long-term management.

Abstract
It has been recently reported that many hirsute women are affected with functional ovarian hyperandrogenism (FOH)-a term that encompasses the heterogeneous polycystic ovary syndrome- and show an abnormal ovarian steroidogenic response to gonadotropin-releasing hormone (Gn-RH) agonists. The aims of the present study were to determine the prevalence of FOH by the assessment of 17-hydroxyprogesterone (17-OHP) response to the Gn-RH agonist buserelin, to correlate these abnormal responses to other parameters suggestive of PCOS, and to assess the possible adrenal origin of hyperandrogenism. Therefore, in 33 consecutive women with hirsutism serum LH, FSH, 17-OHP, dehydroepiandrosterone sulfate (DHEA-S), androstenedione (A), cortisol levels were evaluated in basal conditions and after the administration of buserelin (0.5 mg sc) and ACTH (tetracosactide 0.25 mg iv). Two patients were affected with a non classic congenital adrenal hyperplasia (CAH)-21OH deficiency. In 5 other women ACTH test caused a rate increase 17-OHP (30-0)/30 min > 19 nmol/L/min (0.25 +/- 0.03; mean +/- SE), suggesting the possible existence of heterozygote non classic CAH-21OH. One patient showed a DHEA-S response to ACTH (from 10.3 to 17.2 mumol/L), which was compatible with late-onset 3 beta-Hydroxy-delta 5 steroid dehydrogenase deficiency. Out of the 25 patients with normal responsiveness to ACTH, 11 women (group A) showed higher 17-OHP and A levels, in comparison to normal women, both in basal conditions (17-OHP = 4.18 +/- 0.72 vs 1.74 +/- 0.34 nmol/L, p < 0.005; A = 11.8 +/- 1.2 vs 6.0 +/- 0.7 nmol/L, p < 0.05) and after buserelin (17-OHP = 15.61 +/- 1.31 vs 6.96 +/- 0.9 nmol/L; A = 19.0 +/- 1.9 vs 7.5 +/- 0.8 nmol/L; p < 0.001). In 6 of these 11 patients basal and buserelin-stimulated LH levels were higher than in normals. The remaining 14 patients (group B) showed normal baseline and buserelin-stimulated 17-OHP and A concentrations. In this group only 2 patients had high basal and stimulated LH levels. An augmented LH/FSH ratio was present in 5 and 1 cases of groups A and B, and polycystic ovaries at ultrasonography were observed in 7 and 8 cases of groups A and B, respectively. It is to note that an abnormal 17-OHP response to buserelin was present also in 3 of the 5 patients with abnormal 17-OHP rise after ACTH test, suggesting an adrenal and ovarian cause of hyperandrogenism. In conclusion, an abnormal response to one or both stimulation test was present in 57% of cases: an adrenal origin of hirsutism was detected in 15%, a combined adrenal and ovarian origin was found in 9% and an ovarian cause was present in 33%. Buserelin testing is an useful means to reveal the presence of FOH.

Abstract
OBJECTIVE The standard ACTH test in clinical use employs a pharmacological dose of ACTH which assesses the maximum secretory capacity of the adrenal cortex. We have investigated the responses of plasma adrenocortical steroids including cortisol, aldosterone and dehydroepiandrosterone (DHEA) to physiological doses of ACTH (ACTH 1-24, tetracosactide, Cortrosyn) and determined the minimal dose which induces a response equivalent to that induced by a pharmacological dose of ACTH. DESIGN Rapid ACTH tests at various physiological (0-1, 0.5, 1 and 5 micrograms) and standard pharmacological (250 micrograms) intravenous doses. SUBJECTS Seven healthy normal volunteers. MEASUREMENTS Plasma cortisol, aldosterone and DHEA were measured. Peak value and the increment from basal value were used as indices of responses. RESULTS Each steroid responded to physiological doses of ACTH in a dose dependent manner. The minimum dose inducing an equivalent response to 250 micrograms ACTH was 0.5 micrograms for peak and incremental values in cortisol and DHEA, while that for aldosterone was 0.1 microgram. The time to peak for each steroid was delayed as the dose increased. Plasma aldosterone and DHEA peaked significantly earlier than plasma cortisol in 1-5 micrograms and 0.5-5-micrograms ACTH tests, respectively. CONCLUSIONS These results suggest that the sensitivity of secretion to physiological doses of ACTH in descending order is aldosterone > DHEA = cortisol. When peak and incremental values are used, sufficient doses of ACTH are 0.1 microgram for plasma aldosterone and 0.5 microgram for plasma cortisol and DHEA in the rapid ACTH test.

Abstract
OBJECTIVE To investigate the basal levels of gonadotrophins and sex steroids, with special reference to the effects of obesity and body fat distribution, in premenopausal women, both those with polycystic ovary syndrome (PCOS) and those with normal ovaries and regular menstrual cycles. DESIGN Cross-sectional study. The separate effects of obesity (and body fat distribution and fasting insulin levels) and PCOS on endocrine variables were evaluated by means of analysis of covariance. PATIENTS Sixty-seven women with anovulatory menstrual cycles and polycystic ovaries according to ultrasonography and 59 women with normal ovaries and regular cycles, both groups covering a wide range of body mass index (BMI, PCOS, 17.6-37.4, mean 25.7 kg/m2; controls, 18.8-40.9, mean 25.1 kg/m2). MEASUREMENTS Serum levels of gonadotrophins, sex steroid hormones, prolactin and GH obtained in the early follicular phase in the controls, fasting insulin levels, anthropometric measures (BMI, skinfolds, waist hip ratio). RESULTS Mean serum concentrations of LH, androstenedione, testosterone, the free androgen index (FAI; all P < 0.0001) and DHEAS (P < 0.01) were higher, and serum FSH (P < 0.01) and serum SHBG levels lower (P < 0.0001), in the PCOS group than in the controls. Women with PCOS had a more pronounced upper body fat distribution and higher fasting insulin levels than the controls. Independent of PCOS, BMI was positively associated with serum levels of FSH (P < 0.001) and negatively with levels of LH (P < 0.05), LH/FSH ratio (P < 0.0001), SHBG (P < 0.0001) and androstenedione (P < 0.01), whereas for levels of testosterone, FAI and DHEAS the impact of obesity differed significantly between the groups. Thus, in the PCOS group, testosterone levels (P < 0.05) and the FAI (P < 0.001) were positively associated with BMI, whereas they were constant throughout the entire range of BMI in the controls. DHEAS levels were positively associated with BMI in the PCOS group (P < 0.05) and negatively in the controls (P < 0.01). Measures of upper body fat were related to testosterone and FAI levels, independent of BMI. CONCLUSIONS Lower FSH levels were found in women with PCOS than during the early follicular phase of normally ovulating women, suggesting a role in anovulation in PCOS. Obesity itself exerted effects on endocrine variables, with the net result of a reduced LH/FSH ratio and lower serum levels of androstenedione and SHBG in both groups; obesity was associated with increased levels of DHEAS, testosterone and FAI exclusively in the women with PCOS. The results underline the endocrine impact of obesity and body fat distribution and the necessity of applying reference values of BMI matched subjects when establishing the endocrine profile of women with PCOS.

Abstract
OBJECTIVE Various studies have demonstrated coexistence of ovarian and adrenal hyperandrogenism in women. This study was designed to determine whether testosterone can increase the response of the adrenal gland to stimulation by adrenocorticotrophin (ACTH). DESIGN Non-randomized intervention in a university teaching hospital. PATIENTS Twenty androgen-treated female-to-male transsexual patients (10 ovariectomized and 10 non-ovariectomized) and 10 normal female controls. MEASUREMENTS ACTH stimulation tests were performed in all subjects. Baseline values and the increase above baseline values after ACTH stimulation were assessed for cortisol and the adrenal androgens androstenedione, dehydroepiandrosterone and dehydroepiandrosterone-sulphate. RESULTS Increases in levels of cortisol, androstenedione and dehydroepiandrosterone after administration of ACTH were greater in testosterone-treated transsexual patients than controls. CONCLUSION We conclude that testosterone increases the response of the adrenal gland to stimulation by ACTH.

Abstract
Disorders of androgen excess in women are common in the practice of dermatology. The literature regarding the evaluation and treatment of women with cutaneous hyperandrogenism (acne, hirsutism, and alopecia) is vast and is contained in numerous subspecialty journals. At first glance, the basic science knowledge required to understand androgen biology appears exceedingly complex. However, an understanding of androgen physiology and a familiarity with the relevant literature are the basis of appropriate evaluations and treatment recommendations. In the first of this two-part series, we review the basic science of androgen biology and pathophysiology in women. The second part of this series will cover the evaluation of suspected hyperandrogenic women and the therapeutic modalities that are available.

Abstract
OBJECTIVE We explored the hypothesis that activation of the hypothalamo-pituitary-adrenal axis is involved in the pathogenesis of hyperandrogenism in the polycystic ovary syndrome. PATIENTS Seven women with polycystic ovary syndrome (mean age 27.6 +/- 1.6 (SEM) years) (hirsutism, oligo/amenorrhoea and elevated serum testosterone and dehydroepiandrosterone sulphate) and nine normal female controls (mean age 24.6 +/- 1.5 years) were studied. To exclude anovulation as a confounding factor, four of these normal women were studied in both the follicular and luteal phase of the menstrual cycle. DESIGN AND MEASUREMENTS Plasma ACTH and cortisol levels were measured at 15-minute intervals between 0600 h and 1800 h. ACTH and cortisol mean levels, pulse number and amplitude were calculated using established computer software, programmed to identify ACTH and cortisol peaks. RESULTS With the exception of mean plasma levels of ACTH over the 12-hour period, which were reduced in the luteal phase of the menstrual cycle (1.8 +/- 0.3 pmol/l) compared to the follicular phase (2.3 +/- 0.2 pmol/l, P < 0.05), there were no differences in the pattern of ACTH or cortisol secretion across the normal cycle. In polycystic ovary syndrome, 12-hour ACTH pulse frequency was reduced (3.6 +/- 0.7) compared with controls (5.9 +/- 0.6, P < 0.05), but cortisol pulsatility and ACTH and cortisol mean levels were similar in both groups. CONCLUSION The hyperandrogenism of polycystic ovary syndrome cannot be explained by enhanced ACTH secretion. Normal circulating cortisol levels, yet elevated dehydroepiandrosterone sulphate levels, suggests that polycystic ovary syndrome is yet another example of discrepant adrenal glucocorticoid and androgen secretion, and provides further evidence for a putative adrenal androgen stimulating factor.

Abstract
Cardiovascular diseases are the most important cause of mortality in industrialised countries. Contrary to cancer research, cardiovascular research mostly ignores toxic effects, apart from nicotine, caffeine, alcohol, a few pharmaceutical drugs, and the (in our countries) minor workplace problems carbon disulfide, nitrate esters, and carbon monoxide. But many workplace chemicals are known to be harmful to the cardiovascular system; beside the mentioned, also organic solvents, metals, pesticides, vinyl chloride, polychlorinated biphenyls, etc. Several toxic mechanisms in the cardiovascular system are already known: e.g., long-term development of atherosclerosis, hypertension, coronary heart disease, cardiomyopathy, and arrhythmia. To neglect cardiovascular toxicity is contrary to logic; for many cardiovascular diseases toxic effects may be constitutive; more of these effects may be seen in the future.

Abstract
The postpubertal clinical presentation of 3 beta-hydroxysteroid dehydrogenase deficiency (3B-HSD deficiency) is less well-defined for adult males than for adult females, who often present with hirsutism. We describe a male with normal puberty who presented with new-onset gynecomastia at age 24. Common causes of gynecomastia were excluded. Dehydroepiandrosterone-sulfate (DHEA-S), estradiol, estrone, and 24-hour urinary 17-ketosteroid levels were elevated. A feminizing tumor was considered; biochemical tumor markers, chest x-ray, ultrasound of testes, and abdominal computed tomography (CT) scan were negative. Dexamethasone-suppression testing showed normal suppression of 24-hour urinary adrenal steroids. Cosyntropin-stimulation testing showed normal cortisol, 11-deoxycortisol, 17-OH progesterone (17-OHP), and aldosterone levels, but significant elevations of pregnenolone (preg), 17-OH preg, progesterone, DHEA, and androstenedione (A) levels. The sperm count was high and gonadotropin-releasing hormone (GnRH)-stimulation testing showed a normal increase in testosterone (T) level, suggesting that the defect did not involve the testes. It is concluded that this patient's gynecomastia is due to 3B-HSD deficiency with an associated alteration in sex hormone ratios. To our knowledge, this is the first well-described adult male with normal gonadal function presenting with postpubertal gynecomastia due to 3B-HSD deficiency. This defect may be a frequently unrecognized cause of gynecomastia.
