Abstract
Ectopia of nodular adrenocortical tissue is very frequently found in the periadrenal region. It corresponds to accessory adrenal tissue and is a normal variant. Ectopia in more distant regions are found in inner male or female genitalia. Strong long-lasting hyperstimultions induce hyperplasia and simulate true tumors ("adrenal rest tumors"). Real autonomic tumors from ectopic adrenal tissue with or without hyperfunction are rare. Ectopia of adrenomedullary tissue are nearly exclusively found in the surroundings of normal medulla. Ectopia in the adrenals corresponds almost exclusively with thyroid tissue. Ectopic secretion of hormones, mostly ACTH, can be found in pheochromocytomas and induces hyperfunction (Cushing's syndrome).

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH) consists of a group of diseases characterized by an enzyme deficiency, particularly 21-hydroxylase deficiency. The condition may present in the simple virilizing form or in the salt-wasting form, with varying degrees of genital ambiguity. The non-heterosexual orientation is used in gender studies fields and includes bisexual, homosexual, Lesbians, gays, bissexuals, transgender, intersex, and others. OBJECTIVE The objective of this study was to evaluate the frequency of non-heterosexual orientation in patients with CAH, in an attempt to identify biological factors possibly associated with this occurrence. METHODS This was a descriptive review of observational studies on the sexual orientation of patients with CAH published between 1985 and 2016, as listed in PubMed. RESULTS Various studies have been performed to establish the relationship between CAH and non-heterosexual orientation. Non-heterosexual orientation is more prevalent in patients with more advanced Prader stages and those with the null and I2-splice genotype. CONCLUSION The prevalence of homosexuality and bisexuality is greater in patients with CAH in relation to the general population.

Abstract
The autopsy findings of an adult patient with 21-hydroxylase deficiency are presented. Genetic analysis of the 21-hydroxylase gene (CYP21A2) was performed for accurate diagnosis of congenital adrenal hyperplasia (CAH), and bilateral testicular tumors were characterized. We report a 29-year-old Japanese man who was diagnosed with CAH (21-hydroxylase deficiency) in infancy and had continued steroid therapy until the age of 28. However, for more than one year, he had not been treated for CAH and was found dead. In the medico-legal autopsy findings, both adrenal glands were enlarged, and hypertrophy of adrenal cortices and bilateral testicular tumors positive for melan-A were observed. Genomic DNA was prepared from cervical lymph nodes collected during autopsy, and CYP21A2 was PCR amplified and sequenced directly using newly designed primers. From the morphological findings, the bilateral testicular tumors were considered to be adrenogenital syndrome (TTAGS). Through the whole sequence of CYP21A2, the intron 2 splice mutation (656)A to (656)G was found. TTAGS were thought to be adrenal rests enlarged by ACTH stimulus. From the autopsy findings and the result of genetic analysis, he was diagnosed with the salt-wasting form of 21-hydroxylase deficiency and his cause of death was presumed to be heart failure based on abnormal electrolytes.

Abstract
To determine the influence of age, gestational age, gender and methodological protocol on serum 17OHP and cortisol concentrations. 17OHP in non-extracted (NE) and extracted (E) sera was measured by RIA in 319 full-term (FT) (1 d-5 yr) infants, 38 pre-term (PT) and in 19 neonates with classical CAH at diagnosis. 17OHP (NE- and E-) decreased with age in normal children. The extraction procedure significantly reduced 17OHP by eliminating interfering steroids in children < 1 year. Sexual dimorphism was only observed in NE-17OHP. 17OHP in PT was always higher than in FT up to 2 months of age (p < 0.001). Neither NE- nor E-17OHP in CAH overlapped with those of FT or PT (p < 0.001) allowing to omit the extraction procedure to confirm CAH diagnosis. Cortisol levels were within normal range in neonates with CAH, thus not adding useful information about adrenal function. Chronological and gestational age, gender, and extraction for 17OHP measurement are important factors to know when assessing adrenal function during the first year of life.

Abstract
UNLABELLED Polycystic ovary syndrome (PCOS) is a common disorder of reproductive-aged women. It affects between 3.4-6.8% of this population. Common clinical symptoms of PCOS include menstrual irregularities, hirsutism, and often obesity. Long-term sequelae include anovulatory infertility, endometrial carcinoma, and an increased risk for cardiovascular disease due to type II diabetes mellitus, dyslipidemia, and systolic hypertension. The diagnosis of PCOS is one of exclusion and is defined by the Rotterdam criteria which were established in 2004. However, several other endocrine disorders can closely resemble PCOS. It is important for practitioners to recognize and distinguish PCOS from other disorders in its differential. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader should be able to summarize the short-term reproductive and long-term metabolic consequences of polycystic ovary syndrome (PCOS), point out the importance of meeting the current criteria for diagnosis, and recall the recommended treatment related to the clinical presentation of the patient.

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
During the past 50 years since the discovery of cortisone therapy as an effective treatment for CAH, many advances have been made in the management of 21-hydroxylase deficiency. Despite these advances, the clinical management of patients with CAH is often complicated by abnormal growth and development, iatrogenic Cushing's syndrome, inadequately treated hyperandrogenism, and infertility. New treatment approaches to classic CAH represent potential solutions to these unresolved issues. At the National Institutes of Health, a long-term randomized clinical trial is investigating a new treatment regimen: a reduced hydrocortisone dose, an antiandrogen, and an aromatase inhibitor. Peripheral blockade of androgens may also be helpful in the adult woman with CAH and PCOS. Other promising new treatment approaches include LHRH agonist-induced pubertal delay with or without growth hormone therapy, alternative glucocorticoid preparations or dose schedules, CRH antagonist treatment, and gene therapy. The applicability and success of these new approaches await the results of current research.

Abstract
The aim of this study was to describe the ovarian structure (OS) and its relationship with hyperandrogenism in girls with premature pubarche (PP). A pelvic ultrasound was carried out in 23 girls with PP and in 57 prepubertal age-matched controls (C), and the OS was subdivided into five classes (c): 1-homogeneous; 2-microcystic, 3-multicystic, 4-polycystic and 5-follicular. In the girls with PP, an ACTH test was performed, and the presence of hormonal levels >3 SD of postpubertal normal levels and not compatible with late-onset congenital adrenal hyperplasia were considered an exaggerated response. The fasting levels of glucose (G) and insulin (I) were measured and the fasting I to G ratio (FIGR) was calculated. FIGR >22 was suggestive of I resistance (IR). The microcystic structure (c2) was more frequently found in the PP than in the C group (63% vs 35%, p=0.03). In the PP group, we observed the following OS: cl (n=6), c2 (n=15), c3 (n=1) and c4 (n=1). 11-Deoxycortisol--both basal and after ACTH--was greater in the PPc2 group than in PPc1 (p=0.04, p=0.0008, respectively). We also observed an exaggerated response to ACTH in 87% of the girls with PP, greater in the PPc2 group than in PPc1 (p=0.04). The FIGR showed IR in 44% of girls with PP, but I levels and FIGR were similar between PPc1 and PPc2. These findings suggest generalized adrenocortical hyperresponsiveness in girls with PP, which is more accentuated in PPc2. Long-term follow-up of girls with PP into adulthood is warranted to ascertain whether microcystic ovarian structure precedes functional ovarian hyperandrogenism.

Abstract
The functions of the hypothalamic-pituitary-ovarian and -adrenal axes are intertwined, and molecular defects in either axis may cause ovarian dysfunction. Advances in molecular genetics have allowed new insights into the pathophysiology of ovarian disorders. Specific gene mutations causing delayed puberty and/or ovarian failure, and heterosexual or isosexual precocious puberty have recently been described. The molecular insights gained into ovarian dysfunction have already led to rational therapies for some of these conditions.

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
The hyperandrogenism of polycystic ovary syndrome (PCOS) appears to be due to dysregulation of steroidogenesis within the ovaries and adrenal glands. P450c17 is the key enzyme that regulates androgen synthesis. It is the only enzyme known to have the capacity to convert C21-precursors to the androgen pre-hormones, the 17-ketosteroids. It is a single enzyme with two activities, 17-hydroxylase and 17,20-lyase. Thus, its regulation is a significant factor in the expression of hyperandrogenism. Androgen secretion is LH-dependent in the ovary and ACTH-dependent in the adrenal glands. The androgenic response to each of these tropic hormones seems to be modulated by intra-ovarian or intra-adrenal autocrine and paracrine mechanisms. This modulation serves to regulate steroid hormone secretion in tissue-specific ways. Insulin, IGFs and inhibin are among the many growth factors capable of augmenting the response to LH and ACTH. The insulin/IGF system stimulates P450c17 mRNA expression and activities in the ovaries and adrenal glands. An integrating link between insulin resistance and hyperandrogenemia may be serine phosphorylation, which inhibits activity of the insulin receptor and promotes the 17,20-lyase activity of P450c17. However, it must be kept in mind that there is some evidence for the existence of P450c17-independent pathways of androgen biosynthesis.

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.
