amenorrhea, an absence of menses is a symptom that generally brings teenagers for evaluation. this study was undertaken to determine the etiology of primary amenorrhea with especial concern to non classic congential adrenal hyperplasia (nc-cah)-due 21 hydroxylase deficiency among female adolescents refered to clinics of pediatric endocrinology of tehran and iran university of medical sciences a...

in this study 93 hirsute females (ferryman and gallway score > 8) referred to institute of endocrinology & metabolism and office were assessed. baseline testosterone (tes), dehydroepiandrosterane sulfate (dhea-so4). follicular stimulating hormone (fsh). leuteinizing hormone (lh), prolactin (prl), thyroid stimulating hormone (tsh), baseline 17 hydroxyprogesterone (17 ohp) and in some cases acth ...

Congenital adrenal hyperplasia is attributed to inherited enzyme defects in the adrenal cortex. The classical form results in reduced production of cortisol and aldosterone, accompanied by an increase in production of adrenal cortical androgens. This causes virilisation in girls, adrenocortical failure and early puberty in both sexes. This article describes the genetics, clinical picture, diagn...

Congenital adrenal hyperplasia (CAH) is a rare congenital disorder, which in cases of female genotype may result in virilization. Specific enzyme deficiencies in adrenocorticoid hormones biosynthetic pathway lead to excess androgen production causing virilization. Classic type presents early in infant life as salt losing or simple virilizing type, whereas non classic form presents late at puber...

Congenital adrenal hyperplasia (CAH) is a heterogeneous group of autosomal recessive disorders due to defects in steroid biosynthesis. In about 90% patients, CAH caused by pathogenetic variants CYP21A2 gene, impairing the function 21-hydroxylase (21-OH) enzyme. can present as classical form (simple virilizing or salt wasting) non-classical (NC-CAH). NC-CAH gene that result 20–70% residual activ...

The ACTH test has been used to confirm the diagnosis of adrenal insufficiency and the classic and the non-classic adrenal hyperplasia due to the 3-HSD, 21 OH e 110H deficiencies. This article reviews the historical aspects of the use of ACTH in the diagnosis of hirsutism and points out its mains indications. In spite of new biological molecular advances in the diagnosis of adrenal enzymatic def...

Congenital adrenal hyperplasia was once considered a rare inherited disorder with severe manifestations. Mild congenital adrenal hyperplasia, however, is common, affecting one in 100 to 1,000 persons in the United States and frequently eluding diagnosis. Both classic and nonclassic forms of the disease are caused by deficiencies in the adrenal enzymes that are used to synthesize glucocorticoids...
