Background: Childhood pineal and/or suprasellar intracranial germ cell tumours (IGCT) are highly curable (>90%) with neuraxial radiation alone; international (SIOP) trials have aimed to decrease late radiation-induced neuroendocrine morbidity by substituting chemotherapy. However, without longitudinal study, disease and treatment contributions to long term outcomes remain unknown.Objective: To define tumour and treatment factors implicated in neuroen...

Introduction: Standard dose for GH deficient children is 0.025 mg/kg per day given subcutaneously once daily. Inborn panhypopituitarism is a special subset of GH deficiency. Its management is difficult because several hormones need to be replaced. We present three patients with perinatal onset panhypopituitarism.Case reports: Case 1 is a 7-year-old boy who had hypoglycaemic seizure with reanimation due to circulatory arrest shortly after birth. Panhypopi...

Background: Congenital nephrogenic diabetes insipidus (arginine vasopressin resistance) is a rare inherited disorder characterized by insensitivity of the kidney to the antidiuretic effect of vasopressin. About 90% cases nephrogenic diabetes insipidus is an X-linked recessive disorder caused by variants in the AVP V2 receptor gene (AVPR2). In the remaining cases (10%) the disease is autosomal recessive or dominant and, for these patients, variants in ...

Background: 5-α-reductase type 2 enzyme catalyzes the conversion of testosterone into dihydrotestosterone, a potent androgen responsible for male sexual development during the fetal period. From 2017 to 2019, a homozygous hg38_chr2:31529414 C>T variant in SRD5A2 gene have been identified in 3 unrelated patients with DSD 46,XY of Buryat origin. The variant has been previously reported in one patient from China (Song et al, 2019) and l...

Background: Immunoglobulin superfamily, member 1 (IGSF1) was originally proposed to function as an inhibin co-receptor in pituitary gonadotroph cells. More recently, however, loss of function mutations in the human IGSF1 gene were linked to a novel syndrome of central hypothyroidism, testicular enlargement, and variable prolactin-deficiency. Igsf1-deficient mice are also centrally hypothyroid, with reduced pituitary thyrotropin-releasing hormone receptor (<em...

Background: Crohn’s disease is a relapsing systemic inflammatory disorder with inflammatory bowel disease (IBD) due to up-regulation of pro-inflammatory cytokines including TNFα. More than 80% of newly diagnosed children present with growth failure Paediatric gastroenterology units in the UK submit data to the UK IBD database which can be accessed when required. One aim of current treatment protocols is to promote growth. Studies on the use of anti-TNFα antibodi...

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare pediatric disorder. The classic form occurs in 1:15,000 births worldwide. Osteogenesis imperfecta is a rare bone disease occurring in 1 in 15,000 to 20,000 births. Cow’s milk allergy (CMA) is of the commonest food allergies in early life. Our case presents the co existence of the abovementioned entities in a patient.Case report:</str...

Background: Research on the impacts of achondroplasia on children's functioning and well-being is limited. The purpose of the study was to investigate the impacts of achondroplasia on children's daily lives to support the development of an impact measure of achondroplasia on children's functioning and well-being.Methods: Individual telephone interviews and one parent focus group were conducted in the United S...

Case Description: We report a case of a 7-month old Vietnamese boy who presented with failure to thrive and a Cushingoid appearance from 1 month old. There was no history of exogenous steroid use. On examination, height and weight were <3rd centile. He was Cushingoid with motor development delay. There were multiple large café-au-lait lesions over the sacral region but no limb asymmetry to suggest fibrous dysplasia.En...

Background/Objective: Smoking during pregnancy is known to influence prenatal/postnatal growth of the offspring. We investigated the impact of smoking in the Swedish reference population for new reference for height, weight and BMI, the GrowUp1990Gothenburg cohort.Material/Methods: The study was based on 1907 healthy children (918girls/989boys) born at term in Sweden with Nordic parents and longitudinal growth measurements. 155girls/180b...
