Introduction: Over-production of androgens is linked to prostate cancer (PCa) in men and polycystic ovary syndrome (PCOS) in women. CYP17A1 produces dehydroepiandrosterone (DHEA), the precursor for androgens, via its 17,20 lyase activity. CYP17A1 lyase activity is regulated by the amount of P450 reductase for electron transfer; the presence of cytochrome b5; and protein phosphorylation. High androgen levels were linked to the phosphorylation of CYP17A1 protein...

Background: Low-dose adrenocorticotropic hormone stimulation test (LDST) is widely used to assess patients for adrenal insufficiency. However, the predictive power of basal cortisol for the performance of LDST is not clear.Objective: To determine the appropriate basal serum cortisol cutt-off values that predict a positive or negative LDST.Design: A single-centre retrospective study...

Introduction: Early initiation of diazoxide (DZX) treatment in neonates with HH can prevent permanent hypoglycaemic brain injury. The DZX standard therapeutic dose (STD) is 5 mg/kg/day, and rarely associated with adverse events. There are limited data for the effectiveness and safety of DZX low-dose (<5mg/kg/day) for the treatment of HH neonates.Aim: To assess efficacy and safety of low-dose DZX in HH newborns.<p ...

Anorexia nervosa (AN) manifests in the restriction of energy intake relative to energy output. Atypical AN includes those who meet the criteria for AN but are not underweight. Hypothalamic amenorrhea can be a presenting symptom in AN, and the return of menses is part of recovery. It can take more than a year for menses to return after weight restoration and nutritional rehabilitation. Hypercortisolemia is common in AN, but usually does not cause cushingoid symptoms We describe...

Introduction: There is considerable variation in practice when assessing adrenal function in adrenal insufficiency; duration of glucocorticoid defined to confer risk, early morning cortisol assay (EMC), Synacthen test (ST) - both low dose (LDST) (1microgram) or standard dose (SDST) (36microgram/kg [maximum 250micrograms]) and symptomatology. At our tertiary children’s hospital, even between departments, there is variation in those identified as being at ...

Objective: To report a family with MODY2 associated with GCK gene mutation and improve clinicians' understanding of this gene mutation.Methods: The clinical manifestations, laboratory examinations and genetic test results of a MODY2 family diagnosed and treated in our hospital were analyzed retrospectively, and the related literatures were reviewed.Results: The patient is a 6-...

Turner syndrome (TS) affects 25-50 per 100,000 females and can involve multiple organs through all stages of life, necessitating a multidisciplinary approach to care. Numerous important advances have been noted during recent years. These advances cover all specialty fields involved in the care of girls and women with TS. This new international guideline is based on an international effort with emphasis on 1) diagnostic and genetic issues, 2) growth and development during child...

Background: Transgirls (female-identifying adolescents assigned male at birth) can be treated with GnRH (gonadotropin releasing hormone analogs) followed by the addition of estrogens.Recently in a small cohort of 25 transgirls their average final height was reported to be +1.9 SDS (standard deviation score) calculated for adult Dutch females.High dosage estrogens can be used to stimulate bone maturation, thereb...

Introduction: Primary congenital hypothyroidism (PCH), defined as thyroid hormone deficiency, can be viewed as an anatomical, clinical, biochemical and radiological spectrum.Its etiology includes thyroid dysgenesis (85%) with defects in thyroid gland development and thyroid dyshormonogenesis (15%) with inborn error of thyroxine synthesis or release.There is growing evidence that precise characterization of ...

Background: Paragnagliomas and pheochromocytomas are rare neuroendocrine tumors that originate from the paraganglionic cells of the autonomic nervous systems. These tumors may be extra or intra-adrenal in site. The use of antihypertensive medications is usually challenging in these patients. Long acting alpha and beta blockade can be quite useful preoperatively but challenging postoperatively. We present a case of familial paraganglioma that was successfully t...
