Review
Congenital adrenal hyperplasia due to 21-hydroxylase deficiency is an autosomal recessive disorder caused by gene mutations, and its molecular diagnosis is widely used in clinical practice to confirm the hormonal diagnosis. Hence, considering the miscegenation of the Brazilian population, it is important to determine a mutations panel to optimise the molecular diagnosis. The objective was to review the mutations' distribution among Brazilian regions. Two reviewers screened Brazilian papers up to February 2020 in five databases. The pair-wise comparison test and Holm method were used in the statistical analysis. Nine studies were selected, comprising 769 patients from all regions. Low proportion of males and salt-wasters was identified in the North and Northeast regions, although without significant difference. Large gene rearrangements also had a low frequency, except in the Center-West and South regions (p < 0.05). The most frequent mutations were p.I172N, IVS2-13A/C>G, p.V281L and p.Q318X, and significant differences in their distributions were found: p.V281L was more frequent in the Southeast and p.Q318X in the Center-West and Northeast regions (p < 0.05). Thirteen new mutations were identified in 3.8%-15.2% of alleles, being more prevalent in the North region, and six mutations presented a founder effect gene. Genotype-phenotype correlation varied from 75.9%-97.3% among regions. The low prevalence of the salt-wasting form, affected males and severe mutations in some regions indicated pitfalls in the clinical diagnosis. The good genotype-phenotype correlation confirms the usefulness of molecular diagnosis; however, the Brazilian population also presents significant prevalence of novel mutations, which should be considered for a molecular panel.

Meta-Analysis
BACKGROUND
Congenital adrenal hyperplasia (CAH) is an autosomal recessive condition which leads to glucocorticoid deficiency and is the most common cause of adrenal insufficiency in children. In over 90% of cases, 21-hydroxylase enzyme deficiency is found which is caused by mutations in the 21-hydroxylase gene. Managing individuals with CAH due to 21-hydroxylase deficiency involves replacing glucocorticoids with oral glucocorticoids (including prednisolone and hydrocortisone), suppressing adrenocorticotrophic hormones and replacing mineralocorticoids to prevent salt wasting. During childhood, the main aims of treatment are to prevent adrenal crises and to achieve normal stature, optimal adult height and to undergo normal puberty. In adults, treatment aims to prevent adrenal crises, ensure normal fertility and to avoid the long-term consequences of glucocorticoid use. Current glucocorticoid treatment regimens can not optimally replicate the normal physiological cortisol level and over-treatment or under-treatment is often reported.
OBJECTIVES
To compare and determine the efficacy and safety of different glucocorticoid replacement regimens in the treatment of CAH due to 21-hydroxylase deficiency in children and adults.
SEARCH METHODS
We searched the Cochrane Inborn Errors of Metabolism Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews, and trial registries (ClinicalTrials.gov and WHO ICTRP). Date of last search of trials register: 24 June 2019.
SELECTION CRITERIA
Randomised controlled trials (RCTs) or quasi-RCTs comparing different glucocorticoid replacement regimens for treating CAH due to 21-hydroxylase deficiency in children and adults.
DATA COLLECTION AND ANALYSIS
The authors independently extracted and analysed the data from different interventions. They undertook the comparisons separately and used GRADE to assess the quality of the evidence.
MAIN RESULTS
Searches identified 1729 records with 43 records subject to further examination. After screening, we included five RCTs (six references) with a total of 101 participants and identified a further six ongoing RCTs. The number of participants in each trial varied from six to 44, with participants' ages ranging from 3.6 months to 21 years. Four trials were of cross-over design and one was of parallel design. Duration of treatment ranged from two weeks to six months per treatment arm with an overall follow-up between six and 12 months for all trials. Overall, we judged the quality of the trials to be at moderate to high risk of bias; with lack of methodological detail leading to unclear or high risk of bias judgements across many of the domains. All trials employed an oral glucocorticoid replacement therapy, but with different daily schedules and dose levels. Three trials compared different dose schedules of hydrocortisone (HC), one three-arm trial compared HC to prednisolone (PD) and dexamethasone (DXA) and one trial compared HC with fludrocortisone to PD with fludrocortisone. Due to the heterogeneity of the trials and the limited amount of evidence, we were unable to perform any meta-analyses. No trials reported on quality of life, prevention of adrenal crisis, presence of osteopenia, presence of testicular or ovarian adrenal rest tumours, subfertility or final adult height. Five trials (101 participants) reported androgen normalisation but using different measurements (very low-quality evidence for all measurements). Five trials reported 17 hydroxyprogesterone (17 OHP) levels, four trials reported androstenedione, three trials reported testosterone and one trial reported dehydroepiandrosterone sulphate (DHEAS). After four weeks, results from one trial (15 participants) showed a high morning dose of HC or a high evening dose made little or no difference in 17 OHP, testosterone, androstenedione and DHEAS. One trial (27 participants) found that HC and DXA treatment suppressed 17 OHP and androstenedione more than PD treatment after six weeks and a further trial (eight participants) reported no difference in 17 OHP between the five different dosing schedules of HC at between four and six weeks. One trial (44 participants) comparing HC and PD found no differences in the values of 17 OHP, androstenedione and testosterone at one year. One trial (26 participants) of HC versus HC plus fludrocortisone found that at six months 17 OHP and androstenedione levels were more suppressed on HC alone, but there were no differences noted in testosterone levels. While no trials reported on absolute final adult height, we reported some surrogate markers. Three trials reported on growth and bone maturation and two trials reported on height velocity. One trial found height velocity was reduced at six months in 26 participants given once daily HC 25 mg/m²/day compared to once daily HC 15 mg/m²/day (both groups also received fludrocortisone 0.1 mg/day), but as the quality of the evidence was very low we are unsure whether the variation in HC dose caused the difference. There were no differences noted in growth hormone or IGF1 levels. The results from another trial (44 participants) indicate no difference in growth velocity between HC and PD at one year (very low-quality evidence), but this trial did report that once daily PD treatment may lead to better control of bone maturation compared to HC in prepubertal children and that the absolute change in bone age/chronological age ratio was higher in the HC group compared to the PD group.
AUTHORS' CONCLUSIONS
There are currently limited trials comparing the efficacy and safety of different glucocorticoid replacement regimens for treating 21-hydroxylase deficiency CAH in children and adults and we were unable to draw any firm conclusions based on the evidence that was presented in the included trials. No trials included long-term outcomes such as quality of life, prevention of adrenal crisis, presence of osteopenia, presence of testicular or ovarian adrenal rest tumours, subfertility and final adult height. There were no trials examining a modified-release formulation of HC or use of 24-hour circadian continuous subcutaneous infusion of hydrocortisone. As a consequence, uncertainty remains about the most effective form of glucocorticoid replacement therapy in CAH for children and adults. Future trials should include both children and adults with CAH. A longer duration of follow-up is required to monitor biochemical and clinical outcomes.

There is no pooled information about pelvic floor parameters (muscle assessment, disorders) of women with gynecologicaL endocrinopathies (eg. polycystic ovary syndrome, congenital adrenal hyperplasia, premature ovarian insufficiency). Given that, a systematic review was performed on the Pubmed, Scopus, Google Scholar, Scielo and PEDro databases regarding the main gynecological endocrinopathies [polycystic ovary syndrome (PCOS), premature ovarian insufficiency (POI), congenital adrenal hyperplasia (CAH) and hyperprolactinemia (HPL)] since their inception to April 2020. Data quality assessment was made by the Newcastle-Ottawa Scale (NOS) adapted for cross-sectional studies. A total of 4,272 results were retrieved from all databases. After excluding duplicate results and screening by title and abstract, nine studies were selected for quantitative analysis. Seven studies were performed with women with PCOS and two studies with POI. Women with PCOS presented a higher prevalence of urinary incontinence (UI) among obese women, a higher thickness of the levator ani muscle, and higher levels of muscle activity measured by surface electromyograph when compared to the control women. Regarding POI, there was no association with UI, FI, and POP. NOS found that the quality assessment for these selected studies ranged from 5 to 8. We concluded that higher pelvic muscle activity and volume were found in women with PCOS, with further studies needed to confirm this data. Literature was scant about POI, CAH, and HPL.

Management of congenital adrenal hyperplasia (CAH) requires both glucocorticoid replacement and suppression of adrenal androgen synthesis. It is recommended that children with CAH be treated with hydrocortisone, but the appropriate glucocorticoid regimen in adults is uncertain. In order to review the outcomes of different glucocorticoid regimens in the management of CAH, a systematic search of PubMed/MEDLINE and Web of Science was conducted, including reports published up to 25 February 2019. Studies that compared at least two types of glucocorticoid preparation were included. The following information was extracted from each study: first author, year of publication, number and characteristics of patients and control subjects, types and doses of glucocorticoid regimen used, study design and outcomes [ biochemical tests, weight, height, body mass index (BMI), bone mineral density (BMD)]. A total of 23 studies were included in the qualitative synthesis, with 19 included in the quantitative synthesis. Dexamethasone was associated with the greatest degree of adrenal suppression; there was no significant difference in 17-hydroxyprogesterone (17OHP) and androstenedione levels between patients treated with hydrocortisone or prednisolone. Patients treated with dexamethasone had the lowest BMD and the highest BMI. Although dexamethasone therapy is associated with significantly lower 17OHP and androstenedione levels, it is also associated with more adverse effects. There do not appear to be significant differences between hydrocortisone and prednisolone therapy, and the choice of agent should be based on individual patient factors.

INTRODUCTION
There are increased calls to address psychosocial needs among individuals with classical congenital adrenal hyperplasia (CAH). However, cross-cultural disparities exist in treatment practices and psychosocial outcomes that impact the generalizability of evidence-based recommendations. To date, this disparity has not been quantified. The present scoping review uses a dual approach to contrast rates of CAH diagnosis with CAH psychosocial research rates across countries.
METHODS
Six electronic database searches were conducted for: (1) CAH incidence/birth/prevalence rates; and (2) psychosocial research with affected individuals and their families. Two authors reviewed each abstract for inclusion criteria.
RESULTS
Sixty-eight and 93 full-text articles, respectively, were evaluated for incidence and country. The countries/regions with the highest reported CAH rates are Thailand, Ghana, and India. Those with the greatest portion of psychosocial publications are the USA, Germany, and the UK.
CONCLUSION
A discrepancy exists between those countries with the highest CAH rates and those publishing psychosocial research. Specifically, increased rates of CAH are seen in non-Western countries/regions, whereas most psychosocial research arises out of Western Europe and the USA. Due to cultural differences between these regions, increased global collaboration is needed to both inform psychosocial research and translate findings in ways that are representative worldwide.

Congenital adrenal hyperplasia (CAH) is a genetic condition of the steroidogenic enzymes in the adrenal cortex normally leading to variable degrees of cortisol and aldosterone deficiency as well as androgen excess. Exposure to androgens prenatally might lead to ambiguous genitalia. The fetal brain develops in traditional male direction through a direct action of androgens on the developing nerve cells, or in the traditional female direction in the absence of androgens. This may indicate that sexual development, including sexual orientation, are programmed into our brain structures prenatally. The objective of this study was to perform a systematic review of the literature, investigating sexual orientation in individuals with CAH. The study also aimed at identifying which measures are used to define sexual orientation across studies. The review is based on articles identified through a comprehensive search of the OVIDMedline, PsycINFO, CINAHL, and Web of Science databases published up to May 2019. All peer-reviewed articles investigating sexual orientation in people with CAH were included. Quantitative, qualitative, and mixed methods were considered, as well as self-, parent-, and third-party reports, and no age or language restrictions were enforced on publications. The present review included 30 studies investigating sexual orientation in patients with CAH assigned female at birth (46, XX) ( = 927) or assigned male at birth (46, XY and 46, XX) ( = 274). Results indicate that assigned females at birth (46, XX) with CAH had a greater likelihood to not have an exclusively heterosexual orientation than females from the general population, whereas no assigned males at birth (46, XY or 46, XX) with CAH identified themselves as non-heterosexual. There was a wide diversity in measures used and a preference for unvalidated and self-constructed interviews. Hence, the results need to be interpreted with caution. Methodological weaknesses might have led to non-heterosexual orientation being overestimated or underestimated. The methodological challenges identified by this review should be further investigated in future studies.

BACKGROUND AND OBJECTIVES
11-deoxycorticosterone overproduction due to an adrenal tumor or hyperplasia is a very rare cause of mineralocorticoid-induced hypertension. The objective is to provide the most relevant clinical features that clinicians dealing with patients presenting with the hallmarks of hypertension due to 11-deoxycorticosterone-producing adrenal lesions should be aware of.
DESIGN AND METHODS
We report the case of a patient with an 11-deoxycorticosterone-producing adrenal lesion and provide a systematic review of all published cases (PubMed, Web of Science and EMBASE) between 1965 and 2021.
RESULTS
We identified 46 cases (including ours). Most cases (31, 67%) affected women with a mean age of 42.9 ± 15.2 years and presented with high blood pressure and hypokalemia (average of 2.68 ± 0.62 mmol/L). Median (interquartile range) time from onset of first suggestive symptoms to diagnosis was 24 (55) months. Aldosterone levels were low or in the reference range in 98% of the cases when available. 11-deoxycorticosterone levels were a median of 12.5 (18.9) times above the upper limit of the normal reference range reported in each article and overproduction of more than one hormone was seen in 31 (67%). Carcinoma was the most common histological type (21, 45.7%). Median tumor size was 61.5 (60) mm. Malignant lesions were larger, had higher 11-deoxycorticosterone levels and shorter time of evolution at diagnosis compared to benign lesions.
CONCLUSIONS
11-deoxycorticosterone-producing adrenal lesions are very rare, affecting mostly middle-aged women with a primary aldosteronism-like clinical presentation and carcinoma is the most frequent histological diagnosis. Measuring 11-deoxycorticosterone levels, when low aldosterone levels or in the lower limit of the reference range are present in hypertensive patients, is advisable.

Meta-Analysis
BACKGROUND
Congenital adrenal hyperplasia (CAH) is a group of congenital genetic diseases caused by defective steroidogenesis. Our study aims to systematically analyze the screening results for CAH in Chinese newborns.
METHODS
Studies were searched from PubMed, Web of Science, Cochrane library and some Chinese databases up to September, 2020. Meta-analysis was performed after quality assessment and data extraction.
RESULTS
After a review of 2 694 articles, we included 41 studies enrolling 7 853 756 newborns. In our study, we found that the incidence of CAH in China was 0.43‱ [95% confidence intervals(CI), (0.39‱, 0.48‱)], or 1/23 024 [95%CI, (1/25 757,1/20 815)]. 27 studies were included for analysis of the screening positive rate, which gave a rate of 0.66% [95%CI, (0.54%, 0.78%)]. As for the recall rate of positive cases, 17 studies were included and showed that the recall rate reached 86.17% [95%CI, (82.70%, 89.64%)]. Among the CAH patients, the ratio of males to females was 1.92:1 (119:62), and the ratio of salt wasting (SW) to simple virilization (SV) type was 3.25:1 (104:32). The average 17-hydroxyprogesterone (17-OHP) value of CAH was 393.40 ± 291.85 nmol/L (Range 33-1 300 nmol/L); there was no significant difference between male and female patients (437.17 ± 297.27 nmol/L v.s. 322.25 ± 293.04 nmol/L, =0.16), but a significant difference was found between SW and SV patients (483.29 ± 330.07 nmol/L v.s. 73.80 ± 7.83nmol/L, =0.04).
CONCLUSION
We systematically analyzed the current situation of neonatal CAH screening in China, which will deepen our understanding for future CAH screening and early diagnosis.

PURPOSE
Congenital adrenal hyperplasia (CAH) has been shown to potentially affect psychological adjustment. However, most research has focused on females, and knowledge about psychological challenges in males remains sparse. The aim of this systematic review was therefore to assess these in males with CAH.
METHODS
We systematically searched the OVID Medline, PsycINFO, CINAHL, and Web of Science databases, for articles published up to April 20, 2018, investigating psychological adjustment in males with CAH.
RESULTS
Eleven studies were included in the review. Three main health domains were identified: psychological and psychiatric health, quality of life (QoL), and self-perceptions of reproductive health. Some studies covered more than one health domain. Seven studies explored psychological adjustment and/or the presence of psychiatric symptoms or disorders. Results indicated that males with CAH had more problems related to internalizing behaviors (negative behaviors directed toward the self) and more negative emotionality compared to reference groups. Six studies examined QoL, five of them reporting reduced QoL compared to reference groups. Three studies explored the impact of fertility and sexual health issues on psychological health with varying results from impaired to normal sexual well-being.
CONCLUSIONS
CAH seems to have an impact on males' psychological health. However, the number of identified studies was limited, included few participants, and revealed divergent findings, demonstrating the need for larger studies and highlighting a number of methodological challenges that should be addressed by future research.
