Plasma concentrations of immunoreactive corticotrophin (ACTH) have been determined in 14 patients with untreated Addison's disease and in 42 patients with secondary adrenocortical insufficiency. Basal morning plasma ACTH levels were markedly raised in those with Addison's disease but were either in the normal range or undetectable in the group with secondary adrenocortical insufficiency. In the group with Addison's disease circulating ACTH values showed a definite nyctohemeral rhythm, a pronounced rise in response to insulin-induced hypoglycaemia, and an immediate fall following the intravenous injection of corticosteroids, with a half-life of between 13.5 and 44.2 minutes. When assays were performed with antisera directed against the portion of the ACTH molecule responsible for corticosteroidogenesis (the N-terminal portion) the apparent ACTH concentrations were lower than with antisera directed against the non-steroidogenic (C-terminal) portion of the molecule. This emphasizes that different antisera may give different apparent hormone concentrations, and that the ranges of values obtained in normal and abnormal states must be established for each antiserum.

Signs of virilization, such as clitoromegaly, labio-scrotal fusion, and urogenital sinus may be observed in females with 21-hydroxylase deficiency (21-OHD) and other rare virilizing forms of congenital adrenal hyperplasia (CAH). This makes sex determination difficult, and multiple reconstructive surgeries in the postnatal period may be required. As 21-OHD is an autosomal recessive disease, the chance of any child being affected is one in four and so only one in eight will be an affected female.

Background: Immune checkpoint inhibitors (ICIs) are emerging as important drugs for patients with locally advanced esophageal cancer (EC). Yet, immune-related adverse events (irAEs) may be a major obstacle for these population. Multidisciplinary team (MDT) is an efficient way to deal with such conditions.

Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation (ROHHAD) is a rare syndrome presenting in early childhood associated with a high risk of mortality between 50 and 60%. It is characterised by rapid, early onset of obesity between 1.5-7 years, along with central hypoventilation and hypothalamic dysfunction, such as central hypothyroidism, hyperprolactinemia, disorders of sodium and water balance, growth hormone deficiency, adrenocortical insufficiency, or disorders of puberty and features of autonomic dysregulation.
