Abstract
BACKGROUND AND AIM Anogenital distance (AGD) can serve as a life-long indicator of androgen action in gestational weeks 8-14. AGD has been used as an important tool to investigate the exposure to endocrine-disrupting compounds in newborns and in individuals with male reproductive disorder. Endometriosis and polycystic ovary syndrome (PCOS) are two common gynecological disorders and both are related to prenatal androgen levels. Therefore, we performed a systematic review to evaluate the relationships of AGD with these gynecological disorders. METHODS PubMed, Web of Science, and Embase were searched for published studies up to January 25, 2021. No language restriction was implemented. RESULTS Ten studies were included in this review. Five focused on women with endometriosis, and six investigated women with PCOS. According to these studies, PCOS patients had longer AGD than controls, while endometriosis patients had shorter AGD than controls. In conclusion, this study provides a detailed and accurate review of the associations of AGD with endometriosis and PCOS. CONCLUSION The current findings indicate the longer AGD was related to PCOS and shorter AGD was related to endometriosis. However, further well-designed studies are needed to corroborate the current findings.

Abstract
INTRODUCTION Congenital Adrenal Hyperplasia (CAH) is the most common reason for undifferentiated genital appearance in new-borns. Psychosexual outcome in women with CAH has been rarely evaluated, but it seems to be one of the most important factors determining the indications for the surgical treatment of CAH. OBJECTIVE This is to assess sexual function and the health status (HS) in adult females with CAH who had feminizing genitoplasty in childhood. MATERIAL AND METHOD The protocol was approved by the Ethical Committee, and the hospital database was searched for patients with CAH who had genitoplasty between 1975 and 2000. 57 adult patients were identified, and 9 (18%) patients agreed to participate in the study. Mean age at operation was 5.4 years, and mean follow-up duration was 10.9 years. The Female Sexual Function Index (FSFI) was used to evaluate sexual function, and the 36-item Short Form Health Survey (SF-36) was used to evaluate their health status (HS). A FSFI score < 26,55 was classified as Female Sexual Dysfunction (FSD). The control group consisted of 10 adult female volunteers of comparable age, without any oncological or chronic diseases. Fisher's exact test was used for statistical analysis. RESULTS All patients in the CAH group had female gender identity. One was homosexual, and one reported not having any sexual activity. In the control group, all patients had female gender identity. All were heterosexual and one reported not having any sexual activity. The sexual function in five domains and total score were similar in both groups. More pain was reported in the CAH group as compared with the control group, and it was statistically significant. In the CAH group, 5/9 patients had FSD. In the control group, 4/10 patients had FSD. The difference was statistically insignificant (p = 0.66). Mean SF-36 score in the CAH group was 47.1 points, while it was 46.7 points in the control group. The testosterone level in all CAH patients was within the normal range (0.13-1.1 ng/ml). The 17-OH progesterone level was above normal range in 5/9 (55.6%) patients with CAH. All women in the CAH group were hormonally treated. In the control group, all patients had a normal testosterone level (0.15-0.68 ng/ml); the 17-OH progesterone level was in normal range in this group. DISCUSSION We compared our results with the literature data, which used the same questionnaires as in our study. CONCLUSIONS Health status and sexual function in the traceable CAH patients didn't differ from the control group.

Long-term prednisone versus hydrocortisone treatment in children with classic Congenital Adrenal Hyperplasia (CAH) and a brief review of the literature. ACTA BIO-MEDICA : ATENEI PARMENSIS 2019; 90:360-369.

Abstract
BACKGROUND Debate still exist about the safety of long-term use of prednisone (PD) versus hydrocortisone (HC) for treating children with congenital adrenal hyperplasia -21OH D (CAH). Despite recent developments in congenital adrenal hyperplasia -21OH D (CAH), several issues related to patient growth and final height remain unsolved. Debate still exist about the safety of long-term use of PD versus HC for treating children with CAH. The mechanism by which glucocorticoid therapy interferes with growth is complex and multifactorial. Relatively slight supra-physiologic levels may be enough to blunt growth velocity. An increased risk of developing obesity is another possible consequence of hyper-cortisolism in children with CAH. OBJECTIVES OF THE STUDY To evaluate the anthropometric and biochemical effects of long-term PD versus HC treatment in children with CAH-21OHD. A brief review of the literature is also reported. PATIENTS AND METHODS This retrospective study evaluated linear growth and biochemical data of thirty children with classic CAH (19 females and 11 males), who were on PD (n=22) or HC (n=8) treatment, since their first diagnosis. Clinical data included age, gender, duration of therapy, dose of HC and or equivalent dose of HC in the PD group, blood pressure, height (Ht) and weight. Ht-SDS and BMI were also calculated. Biochemical data included measurement of 17- OH progesterone, cholesterol, triglycerides (TG), HDL, LDL, fasting glucose, and insulin concentrations. HOMA-IR was calculated. Carotid intima-media thickness (CIMT) was measured using high-resolution B-mode ultrasonography. Thirty normal age matched children were used as controls for the anthropometric and CIMT data. RESULTS The age of children and duration of treatment did not differ among the two treatment groups. After a mean of 6 years of treatment, the Ht-SDS and BMI did not differ between the three groups of children. The equivalent hydrocortisone dose of children on prednisone was significantly higher than the dose for the hydrocortisone group. Both systolic and diastolic blood pressures (BP) of children on PD was slightly higher compared to those on hydrocortisone group. However, the BP of the 2 treatment groups was not different compared to control children. Fasting blood glucose, homeostatic model assessment insulin resistance (HOMA-IR), plasma TG, HDL, and cholesterol did not differ among the two treatment groups. LDL levels were significantly higher in the PD group versus the HC group. The mean CIMT did not differ among the two treatment groups but was significantly higher in the treated groups versus controls. There was a significant linear correlation between BMI-SDS and CIMT (r=0.37, p=0.047). CONCLUSIONS Children with CAH-21OHD who were kept on PD therapy for 6.4±2.7 years, since the beginning of diagnosis, have maintained normal linear growth. No difference in BMI, HOMA-IR, or CIMT was detected among the two treated groups. The efficiency, safety and convenience of a single daily dose of PD could be a good and relatively safe alternative to HC for the continuing medical treatment of patients with CAH-21OHD. However, more prospective studies across childhood and adolescence are necessary to draw definitive conclusions.

Abstract
OBJECTIVE An important goal in treating children with congenital adrenal hyperplasia (CAH) is to achieve a normal final adult height (FH). The aim of this study was to describe the clinical presentations and evaluate linear growth and possible factors affecting it in children with CAH. METHODS This is a retrospective study of 56 patients with CAH followed up in a tertiary center for 11 years. Patient's data including demographics, clinical, anthropometric, and laboratory information at presentation and during follow-up period were collected from medical records. RESULTS Fifty-six children (31 females) with CAH were seen at KAMC-Jeddah over 11-year period and 91% were 21-hydroxylase deficient. Of these, 46.4% had hyponatremia and 28.6% had hyperkalemia (21.4% had hyponatremia and hyperkalemia) at presentation. Positive family history was documented in 53.6%. Ambiguous genitalia were present in 72% of females and the majority required corrective surgery. Males had significantly decreased HtSDS versus females and females had significantly higher body mass index. The HtSDS of children who had had higher 17OHP or salt-losing crisis during treatment was significantly lower than those who had normal 17OHP and those who did not have salt-losing crisis, respectively. CONCLUSION The final height outcome in our patients with CAH treated with glucocorticoids is lower than the population norm. Proper control of the disease clinically and biochemically through strict compliance to medical therapy as well as close clinical and laboratory monitoring is an important key to achieve normal final adult height in these patients. Side effects, including overweight, obesity, and hypertension are true risk associations and need timely diagnosis and early management.

Abstract
Objectives: To evaluate the growth parameters in congenital adrenal hyperplasia patients in Jeddah, Saudi Arabia. Methods: This is a descriptive retrospective study over the period of 5 years. Data analysis was using Statistical Package for Social Science. The study included 90 participants in which 61 were girls and 29 were boys aged 0 to 18 years . They were evaluated in Pediatric Endocrinology Clinic at King Abdulaziz University Hospital in Jeddah, Saudi Arabia, between January 2012 and January 2017. Results: A total of 90 subjects, of which 67.8% were females and 32.2% were males. Subjects who were underweight constituted 19.1% of the population, while those who were obese were estimated up to 17.6% of the population. Of the children, 25.7% were suffering from short stature and 74.3% had normal height. Approximately 11.8% of the children who suffered from short stature also suffered from hypothyroidism. Mid-parental height of those who suffered from short stature is 159.8 cm. Conclusion: This study showed a significant effect of congenital adrenal hyperplasia on both height, weight, and body mass index. Risk factors includes glucocorticoids dosage, compliance to treatment, and regular follow up. Personalized treatment approach should be followed with all patients diagnosed with congenital adrenal hyperplasia as well as close monitoring and targeted therapy.

Abstract
The maternal-fetal environment plays an important role in developmental programming of adult disease. Metabolic and hormonal dysfunction during human fetal development accompanies gestational diabetes as a common occurrence in mothers with polycystic ovary syndrome (PCOS), while human fetal androgen excess from congenital adrenal hyperplasia or virilizing tumors precedes PCOS-like symptoms after birth. To date, clinical studies of infant blood levels at term have yet to confirm that human fetal androgen excess promotes PCOS development after birth. Earlier in development, however, circulating androgen levels in the second trimester female human fetus can normally rise into the male range. Furthermore, midgestational amniotic testosterone levels are elevated in female fetuses of PCOS compared with normal mothers and might influence fetal development because experimentally induced fetal androgen excess in animals produces a PCOS-like phenotype with reproductive and metabolic dysfunction. Such alterations in the maternal-fetal environment likely program adult PCOS by epigenetic modifications of genetic susceptibility of the fetus to PCOS after birth. Understanding this phenomenon requires advanced fetal surveillance technologies and postnatal assessment of midgestational androgen exposure for new clinical strategies to improve reproduction in PCOS women, optimize long-term health of their offspring, and minimize susceptibility to acquiring PCOS in future generations.

Abstract
OBJECTIVE: The purpose of this study was to identify factors that might interfere with reaching the final height in patients with 21-hydroxylase deficiency (21-OHD). SUBJECTS AND METHODS: Thirty-one patients with classical 21-OHD who reached their FH in our Institution were evaluated in order to compare the Z score for final height (FHZ) with: (1) the target height, (2) the standard height for the population, and (3) the hydrocortisone treatment schedule. RESULTS: The FHZ of -2.13 ± 1.11 had a significant negative correlation with the hydrocortisone doses used throughout the period of study. Patients who reached FH within the normal population range were those who received lower doses of hydrocortisone, as compared to those whose FH remained below -2 SDS. CONCLUSION: We conclude that careful treatment adjustments have a major influence on growth of children with CAH, and that the dose range for hydrocortisone replacement that does not lead to side effects is relatively narrow. The better height outcome was achieved in 21-OHD patients who received lower doses of hydrocortisone.

Abstract
BACKGROUND Early prenatal androgenization (PA) accelerates follicle differentiation and impairs embryogenesis in adult female rhesus monkeys (Macaca mulatta) undergoing FSH therapy for IVF. To determine whether androgen excess in utero affects follicle development over time, this study examines whether PA exposure, beginning at gestational days 40-44 (early treated) or 100-115 (late treated), alters the decline in serum anti-Mullerian hormone (AMH) levels with age in adult female rhesus monkeys and perturbs their ovarian response to recombinant human FSH (rhFSH) therapy for IVF. METHODS Thirteen normal (control), 11 early-treated and 6 late-treated PA adult female monkeys had serum AMH levels measured at random times of the menstrual cycle or anovulatory period. Using some of the same animals, basal serum AMH, gonadotrophins and steroids were also measured in six normal, five early-treated and three late-treated PA female monkeys undergoing FSH therapy for IVF during late-reproductive life (>17 years); serum AMH also was measured on day of HCG administration and at oocyte retrieval. RESULTS Serum AMH levels in early-treated PA females declined with age to levels that were significantly lower than those of normal (P < or = 0.05) and late-treated PA females (P < or = 0.025) by late-reproductive life. Serum AMH levels positively predicted numbers of total/mature oocytes retrieved, with early-treated PA females having the lowest serum AMH levels, fewest oocytes retrieved and lowest percentage of females with fertilized oocytes that cleaved. CONCLUSIONS Based on these animals, early PA appears to program an exaggerated decline in ovarian reserve with age, suggesting that epigenetically induced hormonal factors during fetal development may influence the cohort size of ovarian follicles after birth.

Abstract
Hydrocortisone acetate is usually employed in the treatment of classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. In Brazil, however, oral hydrocortisone acetate is only available from manipulation pharmacies. Prednisolone has stable oral pharmaceutical formulations commercially available, with the advantage of a single daily dose. The aim of this study was to compare the efficacy of oral prednisolone and oral hydrocortisone in the treatment of CAH due to 21-hydroxylase deficiency. Fifteen patients with mean (SD) chronological age of 7.2 (3.6) years, were evaluated in two consecutive 1-year periods. In the first year, hydrocortisone (17.5 mg/m2/day, divided in three doses) was used in the treatment, followed by the use of prednisolone (3 mg/m2/day, once in the morning) in the second year. The comparison between the two treatments was assessed after a one-year treatment period by: variation of height standard deviation score (SDS) (delta Height SDS), variation of height SDS according to bone age (delta BA SDS), variation of body mass SDS (delta BMI SDS) and serum levels of androstenedione. No significant difference was observed in relation to the delta Height SDS, delta BA SDS and delta BMI SDS. No significant difference was observed in the serum levels of androstenedione. We conclude that the efficacy of prednisolone administered once a day orally is comparable to the oral use of hydrocortisone three times a day. Oral prednisolone may be an option for patients with CAH due to 21-hydroxylase deficiency.

Abstract
Infertility in women has many possible causes and must be approached systematically. The most common cause of medically treatable infertility is the polycystic ovary syndrome (PCOS). This syndrome is common in young women and is the cause of anovulatory infertility in 70% of cases. It is therefore an important condition to screen and manage in primary care medical settings. In the past 10 years, insulin sensitization with weight loss or metformin has been shown to be a safe and effective treatment for PCOS infertility that eliminates the risk of multiple pregnancy and may reduce the risk of early pregnancy loss as compared with ovulation-inductor drugs. The authors believe metformin should be considered as first-line therapy because it has the advantage to allow for normal single ovulation, for reduced early pregnancy loss, and, most importantly, lifestyle modifications and weight loss before pregnancy. Losing weight not only improves fertility but also reduces adverse pregnancy outcomes associated with obesity.

Abstract
The prenatal testosterone (T)-treated adult female rhesus monkey is one animal model of polycystic ovary syndrome (PCOS) in women, with early prenatal T excess programming a permanent PCOS-like phenotype characterized by luteinizing hormone (LH) hypersecretion from reduced hypothalamic sensitivity to steroid negative feedback and relative insulin excess from increased abdominal adiposity. These combined reproductive and metabolic abnormalities are associated with ovarian hyperandrogenism and follicular arrest in adulthood, as well as premature follicle differentiation and impaired embryo development during gonadotropin therapy for in vitro fertilization (IVF). A second animal model for PCOS, the prenatal T-treated sheep also is characterized by LH hypersecretion from reduced hypothalamic sensitivity to steroid negative feedback, persistent follicles and insulin resistance, but also is associated with intrauterine growth retardation and compensatory growth after birth. The ability of prenatal T excess in both species to alter the developmental trajectory of multiple organ systems in utero provides evidence that the hormonal environment of intrauterine life programs target tissue differentiation, raising the possibility that T excess in human fetal development promotes PCOS in adulthood. Such a hypothesis must include data from clinical studies of PCOS women to clarify the homology between these PCOS-like animal models and PCOS per se in reproductive and metabolic function. Future studies should develop new clinical strategies that improve pregnancy outcome and minimize pregnancy loss in women with disorders of insulin action, including PCOS, obesity and diabetes mellitus as well as minimize transgenerational susceptibility to adult PCOS and its metabolic derangements in male close relatives.

Abstract
Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a common autosomal recessive disorder characterized by impaired adrenocortical and adrenomedullary function, and adrenal hyperandrogenism. Compared to normal subjects, patients with classic CAH have increased incidence of obesity and visceral adiposity, hyperinsulinism and insulin resistance, hyperleptinemia, hypertension, and hyperandrogenism. It is likely that the impaired adrenomedullary function and intermittent treatment-related hypercortisolism may account for the above abnormalities, and may predispose these subjects to the development of metabolic syndrome-related endothelial dysfunction and atherosclerotic cardiovascular disease in adulthood. Nonpharmacologic and pharmacologic interventions targeting obesity and/or insulin resistance may offer an improved outcome in terms of cardiovascular morbidity.

Abstract
The prenatally androgenised female rhesus monkey has become a model for polycystic ovary syndrome (PCOS) in women, with early prenatal androgenisation entraining a permanent PCOS-like phenotype characterised by luteinising hormone (LH) hypersecretion due to reduced hypothalamic sensitivity to steroid negative feedback and relative insulin excess associated with increased abdominal adiposity. These combined reproductive and metabolic abnormalities occur in combination with ovarian hyperandrogenism and follicular arrest in adulthood, and with premature follicle differentiation and impaired embryo development during gonadotrophin therapy for in vitro fertilization (IVF). The ability of prenatal androgen excess in fetal rhesus monkeys to entrain multiple organ systems in utero provides evidence that the hormonal environment of intrauterine life programmes target tissue differentiation, raising the possibility that hyperandrogenism in human fetal development promotes PCOS in adulthood. This hypothesis developed in prenatally androgenised female rhesus monkeys, however, also must include data from clinical studies of PCOS to clarify the homology between human and non-human primates in intrafollicular steroidogenesis and its impact on oocyte developmental competency. By doing so, future studies promise to develop new clinical strategies that will lead to improved pregnancy outcome and reduced pregnancy loss in women with disorders of insulin action, including PCOS, obesity and diabetes mellitus.

Abstract
OBJETIVOS: identificar a percepção e os mecanismos de enfrentamento utilizados por pais frente à ambigüidade genital de seus filhos em suas diversas etapas evolutivas. MÉTODOS: estudo qualitativo, baseado nos relatos de 15 pais, todos de diferentes famílias, sobre seus anseios no desenvolvimento da criança. Realizado no ambulatório de patologias endócrino-genéticas do Hospital Geral César Cals, no Ceará, em 2004. RESULTADOS: as categorias que emergiram através do discurso dos sujeitos foram: o medo e a ansiedade, e os mecanismos de enfrentamento foram: a negação; a fuga; a regressão/projeção e a racionalização. Observou-se que as tensões e angústias no período neonatal são expressas através do medo da morte, da doença incurável e dos medicamentos. No período infantil, do procedimento cirúrgico (genitália ambígua) e da sexualidade (homossexualismo). Na projeção da fase puberal e adulta há o temor da marginalização, do preconceito, da homossexualidade e da infertilidade. As angústias relatadas foram de quem seria a culpa, a definição sexual (ambigüidade) e a necessidade do segredo. CONCLUSÕES: a genitália ambígua consiste em uma patologia de alta complexidade, que desestabiliza a harmonia psicológica familiar. Nas situações de ambigüidade genital, a detecção e desmistificação dos medos e anseios dos pais devem fazer parte do plano terapêutico.

Abstract
The aetiology of polycystic ovary syndrome (PCOS) remains unknown. This familial syndrome is prevalent among reproductive-aged women and its inheritance indicates a dominant regulatory gene with incomplete penetrance. However, promising candidate genes have proven unreliable as markers for the PCOS phenotype. This lack of genetic linkage may represent both extreme heterogeneity of PCOS and difficulty in establishing a universally accepted PCOS diagnosis. Nevertheless, hyperandrogenism is one of the most consistently expressed PCOS traits. Animal models that mimic fetal androgen excess may thus provide unique insight into the origins of the PCOS syndrome. Many female mammals exposed to androgen excess in utero or during early post-natal life typically show masculinized and defeminized behaviour, ovulatory dysfunction and virilized genitalia, although behavioural and ovulatory dysfunction can coexist without virilized genitalia based upon the timing of androgen excess. One animal model shows particular relevance to PCOS: the prenatally androgenized female rhesus monkey. Females exposed to androgen excess early in gestation exhibit hyperandrogenism, oligomenorrhoea and enlarged, polyfollicular ovaries, in addition to LH hypersecretion, impaired embryo development, insulin resistance accompanying abdominal obesity, impaired insulin response to glucose and hyperlipidaemia. Female monkeys exposed to androgen excess late in gestation mimic these programmed changes, except for LH and insulin secretion defects. In utero androgen excess may thus variably perturb multiple organ system programming and thereby provide a single, fetal origin for a heterogeneous adult syndrome.

Abstract
The medical management of children with congenital adrenal hyperplasia (CAH) can be challenging with regard to optimizing final height. Insufficient glucocorticoid suppression of adrenal hormone production will result in acceleration of bone maturation and premature epiphyseal fusion, while appropriate or excessive glucocorticoid therapy can be accompanied by suppression of the growth axis. The extent of the growth suppression appears to be affected by the type and dose of glucocorticoid. Some studies suggest that such growth suppression can be ameliorated through concomitant use of growth hormone (GH) therapy. Available data published over the last 10 years on height outcomes in CAH patients treated with glucocorticoids will be reviewed.

Abstract
Replacement schedules with hydrocortisone (HC) to treat 21OHD are generally unsatisfactory and partially successful regarding growth. Noncompliance is common since its short half-life requires TID administration. Even multiple daily HC doses do not reproduce cortisol chronobiology and may disturb hypothalamic-mediated rhythms. Because synthetic glucocorticoids could improve clinical control, we evaluated the possible benefits of a one-year treatment period with a single morning oral dose of prednisolone (PD) phosphate in 44 patients with 21OHD randomized to two sex and age-matched groups: one (n=23) receiving PD (2.4-3.5 mg/m2 BSA) and the other (n=21) TID HC (10-15 mg/m2 BSA). After one year, bone maturation ratio was kept stable in the PD group (from 1.20 to 1.14), whereas a slight increase was seen in the HC group (from 1.21 to 1.29). Growth velocity (SDS) was preserved in the PD group (from 1.2 to 1.2 in all; 0.79 to 1.13 in pre-pubertals), whereas a slight increase occurred in the pre-pubertal HC-treated patients (from 1.1 to 1.9); height SDS for BA increased significantly in the PD group. Thus, patients with 21OHD treated for one year with a single morning dose of PD appear to achieve a better clinical and hormonal control than those on TID HC, permitting a reduction of the replacement dose. The current PD schedule used by our group (1.5-3 mg/m2 BSA/day) suggests a higher HC:PD bioequivalence ratio of 6-8:1.

Abstract
As part of a larger study of psychosexual development and sexual functioning in women with congenital adrenal hyperplasia (CAH), we assessed self-reported sexual arousability with the Sexual Arousability Inventory-Short Form (SAI-SF; Hoon & Chambless, 1998). Compared to their unaffected sisters/female cousins (n = 15), women with CAH (n = 30) reported significantly lower sexual arousability on the SAI, with an effect size, using Cohen's d, of 1.16. For both the CAH women alone and combined with the controls, higher self-reported sexual arousability was significantly associated with (a) relationship status (married or cohabitating with a man versus being single or not in a relationship); (b) higher levels of sexual attraction to men in fantasy in the past 12 months on the Erotic Response and Orientation Scale (Storms, 1980); (c) higher Kinsey interview ratings of a heterosexual orientation in behavior in the past 12 months; and (d) more sexual experiences with men, according to a modified version of the Zuckerman (1973) Heterosexual Experience Scale (HES), in the past 12 months and lifetime (all ps < .001-.05). CAH women who were simple virilizers (versus salt-wasters) and those assigned female at birth (versus delayed or male) tended to report higher levels of sexual arousability (p < .10). Self-reported degree of satisfaction with genital surgery and genital function was also associated with higher levels of arousability. For CAH women and both groups combined, multiple regression analysis showed that the sole predictor of self-reported sexual arousability was HES lifetime sexual experiences with men. We discuss the results in the context of assessing sexual function and dysfunction in women with CAH.

Abstract
OBJECTIVE The management of children with congenital adrenal hyperplasia (CAH) remains a challenge, especially with regard to growth potentials. The objective of our analysis was to uncover the factors that influence the growth and final height of patients with CAH. DESIGN The linear growth pattern and body mass index (BMI) at different developmental stages (birth to 2 years, 2 years to puberty initiation and puberty initiation to final height) and the final height achieved were analysed retrospectively in 48 patients with 21-hydroxylase deficiency; 17 with the salt-wasting (SW) form, 25 with the simple virilizing (SV) and six with the nonclassical (NC) form. RESULTS Mean final height (FH) and FH-SDS were, respectively, 170.8 +/- 5.6 m and -0.57 +/- 0.8 in males and 156.7 +/- 6 cm and -0.61 +/- 1 in females with the SW form, 166.1 +/- 6.1 cm and -1.05 +/- 1 in males and 151.6 +/- 5.4 cm and -1.4 +/- 1 in females with the SV form and 159.7 +/- 6.9 cm and 0.3 +/- 1.4 in females with the NC form. In subjects with the SW form, height SDS at 2 years, at puberty initiation and at FH were -0.18 +/- 0.9, 0.11 +/- 1.28 and -0.6 +/- 1.0, respectively. FH achieved was not different from target height (TH) in the SW group, but it was significantly lower than TH in the SV group (P = 0.003). FH in the SW group showed a positive correlation to the height achieved at 2 years of age (r = 0.68, P = 0.019), and height at 2 years was negatively related to the hydrocortisone dose in the birth to 2-year period (r = -0.79, P = 0.011). FH showed no correlation to hydrocortisone dose at any of the three developmental periods studied. BMI-SDS were not different in the various forms of CAH and showed no correlation to FH or hydrocortisone dose. Age at menarche was comparable to that in our general population. CONCLUSIONS Under our conditions of management, the final height of patients with the salt-wasting form was comparable to the target height and to the most favourable literature data. The patients with the simple virilizing form fare less well, mainly due to delayed diagnosis and consequent advancement of bone age and early puberty. In salt-wasting patients, height at 2 years is comparable to normals, it is influenced by the hydrocortisone dose and is related to the final height. Some height is lost during puberty. Hence, monitoring treatment over the first 2 years and during puberty is critical for the outcome in these patients.

Abstract
Classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency is characterized by a defect in cortisol and aldosterone secretion and adrenal hyperandrogenism. Current treatment is to provide adequate glucocorticoid and mineralocorticoid substitution to prevent adrenal crises and to suppress excess adrenal androgen secretion. Satisfactory adrenocortical suppression often requires supraphysiological doses of hydrocortisone, which may produce an unacceptable degree of hypercortisolism. A new four-drug treatment regimen of flutamide, testolactone, reduced hydrocortisone dose, and 9alpha-fludrocortisone has been shown to achieve normal growth and development after 2 yr of therapy and may, therefore, represent a potential alternative approach to the treatment of children with classic congenital adrenal hyperplasia. We investigated the effect of flutamide and testolactone, and flutamide alone, on cortisol clearance by performing clearance studies twice in 13 children (6 males and 7 females; age range, 7.0-14.5 yr) with classic 21-hydroxylase deficiency. All studies were conducted at least 3 months after institution of the four-drug treatment regimen. In eight patients (group 1), the first cortisol clearance study was performed on the four-drug regimen, and the second study was performed after a 48-h washout period off flutamide and testolactone. In five patients (group 2), the first study was conducted 1 wk after discontinuation of testolactone and while patients were receiving flutamide, hydrocortisone and 9alpha-fludrocortisone, and the second study was performed after a 48-h washout period off flutamide. Oral hydrocortisone was held on the day of the clearance studies, and all patients received a continuous infusion of hydrocortisone (0.6 mg/m(2).h) from 1800 h to 0200 h, with cortisol concentrations measured once hourly. In addition, an in vitro study was conducted to exclude the possibility of an analytical interference of flutamide, 2-hydroxyflutamide, and testolactone with the serum cortisol immunoassay. Total body cortisol clearance was significantly lower during treatment with the four-drug regimen than during treatment with hydrocortisone and 9alpha-fludrocortisone (153.5 +/- 26.8 vs.355.4 +/- 65.8 ml/min; P = 0.001). Similar results were obtained comparing flutamide, hydrocortisone, and 9alpha-fludrocortisone therapy to hydrocortisone and 9alpha-fludrocortisone therapy (155.8 +/- 26.5 vs. 281.8 +/- 96.2 ml/min; P = 0.037). The in vitro study indicated that an interference with the serum cortisol immunoassay was unlikely. These findings indicate that the addition of flutamide and testolactone to the treatment regimen of hydrocortisone and 9alpha-fludrocortisone decreases cortisol clearance in patients with classic 21-hydroxylase deficiency, and this effect seems to be due to flutamide. Glucocorticoid replacement doses should be reduced when flutamide is added to the treatment regimen of patients receiving hydrocortisone.

Abstract
Cognition in patients with CAH has not been as well studied as other aspects of psychologic function. Nevertheless, it is possible to make some conclusions and to offer a number of hypotheses for further study (Table 1). First, patients with CAH do not seem to have an overall intellectual advantage as a direct consequence of the disease. The high IQs reported in some groups of patients with CAH are also reported in their siblings and probably reflect sampling bias. Second, it is possible that, on average, patients with salt-wasting CAH have lower overall ability than patients with the simple-virilizing form, but both groups are well within the normal range, and there is considerable variability among both groups. Third, the evidence to date does not confirm that patients with CAH are more likely to have diagnosable learning disabilities when compared with their unaffected relatives, but this issue has not been well studied with the appropriate psychoeducational assessments. It is unlikely that patients with CAH are at substantially increased risk for frank learning disabilities, but they may be likely to have problems in specific areas. Fourth, females with CAH seem to have enhanced spatial ability as a result of exposure to high levels of androgens early in development. The neural substrate of this advantage is unknown but a subject of active research. It is unclear whether when compared with their unaffected siblings, females with CAH are better in other abilities that are typically performed best by males or worse in abilities typically performed best by females. Fifth, it is likely that patients with CAH have other cognitive changes as a consequence of disease characteristics (besides androgens) and of the treatment of the disease. Some evidence suggests that patients with CAH are more likely to have white-matter brain changes produced by the disease and its treatment. This has not been well studied but should be because of the potential clinical implications. It is reasonable to hypothesize that there will be cognitive changes that reflect effects of undertreatment (e.g., ACTH effects on attention) and other changes that reflect effects of overtreatment (e.g., glucocorticoid effects on memory). Some of these effects may be transient, reflecting acute brain changes, whereas others may become chronic as a result of permanent brain changes with repeated exposure. There is need for continuing study of cognition in patients with CAH. Such studies will provide basic information about hormonal effects on cognition and the neural mechanisms that mediate those effects. They will also provide important clinical information to guide psychologic and medical treatment of patients.
