Background: Congenital adrenal hyperplasia (CAH) is a rare condition characterised by adrenal insufficiency and a life-long risk of adrenal crises. There is a paucity of information on the epidemiology of acute adverse events in this population.Objective: To investigate the frequency, aetiology and consequences of acute adverse events attributed to adrenal insufficiency in CAH.Methods</stro...

Aims: Historical I-CAH data shows considerable variation in the management of 21-hydroxylase deficiency (21-OHD) congenital adrenal hyperplasia (CAH) in infancy despite existence of several guidelines. Using the I-CAH registry we analysed contemporary early infancy natural history data, creating benchmarks as part of continuous quality improvement.Methods: Of 136 infants born in 2018-2023 and treated for 21-OHD CAH withi...

Background: Monogenic diabetes mellitus (DM) is an early-onset, non- autoimmune diabetes. Genetic diagnosis can personalize patient management and lead to prevention. We describe four generations of DM in one family, caused by a heterozygous mutation in the RFX6 gene. RFX6 (Regulatory factor X, 6) is essential for the development of the endocrine pancreas. Mutations in RFX6 can cause neonatal (Mitchell-Riley syndrome) as well as childhood DM,...

Introduction: 17α-hydroxylase deficiency (17OHD) is a rare form of congenital adrenal insufficiency characterized with decreased cortisol and sex steroid biosynthesis, overproduction of ACTH, and increased mineralocorticoids. The overproduction of corticosterone hinders the symptoms of glucocorticoid deficiency and causes sodium retention, hypertension, and hypokalemia in severe cases. Affected 46,XX and 46,XY individuals are phenotypically female in the...

Introduction: Although the majority of the cases with obesity have a multifactorial etiology, rare monogenic forms of obesity exist. Several genetic disorders have been described that lead to early onset monogenic obesity. Leptin (LEP), leptin receptor (LEPR), melanocortin 4 receptor (MC4R), proprotein converting protein subtilisin / kexin-type 1 (PCSK1) and proopiomelanocortin (POMC) are the genetic mutations that have been most frequently shown to cause mono...

We report a case of hereditary hypophosphatemic rickets with hypercalciuria (Hereditary Hypophosphatemic Rickets with Hypercalciuria, HHRH) in a 13-year-old boy, referred for evaluation due to the onset of bilateral knee pain for about two years. Pain was intermittent and walking limiting and negatively affected quality of life. Negative family history of bone/joint pathologies and kidney stones. The parents are consanguineous (first cousins), have normal stature and no histor...

Homozygous loss-of-function mutations of the calcium-sensing receptor gene (CaSR) are associated with neonatal severe hyperparathyroidism (NSHPT), a life-threatening condition with a challenging treatment approach.We report a 7-day-old-female infant who was admitted to our Pediatric Department due to poor sucking. On examination she was lethargic and hypotonic. Laboratory evaluation revealed extreme hypercalcemia of 23.54 mg/dL (N: 7.6–10.4...

Introduction: Virilization and hirsutism are clinical findings of androjen excess in females mostly due to polycystic ovary syndrome, although androgenic drugs, nonclassic congenital adrenal hyperplasia and androgen secreting adrenal/ovarian lesions are also implicated. 46, XX ovotesticular disorder of sex development (DSD) is the rarest form of DSD with an incidence of less than 1 in 20000.Case report: A 15-year-old ado...

Objective: The aim of the study was to describe the etiologic diagnosis, clinical characteristics in children with 46,XY disorder of sexual development (DSD).Methods: The 125 46, XY patients were included the retrospective study. The definitive diagnosis was made by presentations and clinical findings, gonadal morphology and genital anatomy of patients, basal and stimulated hormone results, imaging methods and molecular ...

Introduction: Congenital lipoid adrenal hyperplasia is the most severe form of congenital adrenal hyperplasia and is rarely seen. Steroid synthesis cannot be done in the adrenal gonads. Adrenal glands have hyperplasia and lipid accumulation. Male babies are born to girls. Most of the cases are lost with severe adrenal insufficiency. Patients diagnosed and treated at supraphysiological doses during neonatal period. Here we present a case of lipoid adrenal hyperplasia diagnosed ...
