Introduction: Osteopetrosis (OP) is a rare genetic disorder that is characterized by abnormal osteoclast function resulting in dense bones and marrow failure. The only definitive cure for OP is stem cell transplantation (SCT). Hypercalcemia is a well described complication in children with OP undergoing SCT. This study describes the calcium profile and treatment modalities used to maintain normocalcemia in children with OP undergoing SCT.<p class="abstext"...

Background: In males with congenital hypogonadotropic hypogonadism (CHH), LH/FSH stimulation of gonads is deficient. In clinical practice, two hormone replacement strategies are employed to induce and maintain virilisation: Treatment with testosterone and gonadotropin replacement with hCG/rFSH.Objective: To delineate the role of gonadotropins in pathways of male androgen biosynthesis and to thereby better define the gona...

Background: Aldosterone synthase deficiency (ASD) is caused by biallelic inactivating CYP11B2 variants. Infants mainly present with failure to thrive and salt wasting in early infancy. Moreover, different factors may cause downregulation of aldosterone synthase and secondary deficiency.Objective and Hypotheses: We present a toddler with polyuria and polydipsia and steroid hormone precursors suggestive of ASD, bu...

Aim: To study the clinical profile of Neonatal Diabetes Mellitus (NDM) at our centreObjectives: 1. To study follow-up data on growth, glycemic control2. To review genetic analysisIntroduction: NDM is rare and occurs at a frequency of 1:1,00,000. There is scarce literature on follow up of these patients although genetic data is well established (1). Developing...

Background: Congenital Hyperinsulinism (CHI), a condition characterised by dysregulation of insulin secretion from the pancreatic beta cells, remains one of the most common causes of hyperinsulinemic, hypoketotic hypoglycaemia in the newborn period. Mutations in ABCC8 and KCNJ11 constitute the majority of genetic forms of CHI. Biallelic inactivating mutations (homozygous or compound heterozygous) in ABCC8 and KCNJ11 are know...

Background: Growth hormone deficiency (GHD) requires long-term daily injections with GH replacement therapy and is associated with considerable treatment burden by patients and caregivers. Somapacitan is a long-acting GH derivative that is being developed for once-weekly dosing in adults and children with GHD. A well-established protraction method, which is successfully in use to extend the half-life of insulin and glucagon-like peptide (GLP)-1, has been applied in developing ...

Introduction: The Short Synacthen Test (SST) is the most popular diagnostic investigation of adrenal insufficiency (AI) amongst adult and paediatric endocrinologists. AI can present insidiously and symptoms may be non-specific. The number of medical indications for glucocorticoids is growing and SST usage is correspondingly increasing. There is evidence that an early morning plasma cortisol (EMC) of below ~100–150 nmol/l is highly predictive of failing the SST and the cor...

Introduction: The Short Synacthen Test (SST) is the most popular diagnostic investigation of adrenal insufficiency (AI) worldwide. Symptoms of AI are frequently non-specific, often delaying diagnosis, however fortunately cases of adrenal crisis remain relatively rare. Diagnostic cut-offs for plasma cortisol on SST are controversial, made more complicated by modern assays and paediatric normative values extrapolated from adult data. Some advocate a division between biochemical ...

Background: Steroidogenic factor (SF1, NR5A2) regulates multiple genes known to be involved in gonadal development, adrenal development, steroidogenesis, and gonadotroph development. Heterozygous mutations in the NR5A1 gene have been described in association with mild to severe gonadal dysgenesis with or without adrenal failure. Homozygous mutations are rare and have also been described in association with gonadal dysgenesis with or without adrenal failure.<p class="abstex...

Introduction: Only 1.8% of thyroid malignancies occur during childhood, explaining very limited pediatric data. Most frequent in children are papillary thyroid carcinoma (PTC), occurring after exposure to radiation, and presenting as a thyroid nodule ± cervical lymph nodes. PTC may present as diffusely infiltrating disease of the thyroid with microcalcifications. We report an uncommon presentation of a PTC in a 7 year old boy.Case report: The boy wa...
