Background: A total of 456 skeletal dysplasias have been classified by molecular, biochemical and/or radiological criteria, into 40 groups. Despite this, the precise, final diagnosis is often difficult due to the high phenotypic and genotypic variability.Objective: To improve the molecular and clinical diagnosis of skeletal dysplasias using a custom-designed next-generation sequencing (NGS) panel.Method: A total of 56 skeletal dysp...

Background: Low birth weight (LBW) followed by a rapid postnatal catch-up in weight predisposes individuals to a central distribution of body fat, which is reverted by metformin. Growth-and-differentiation-factor-15 (GDF15) plays an important role in the regulation of energy homeostasis, reducing food intake and lowering body weight. We aimed to assess whether GDF15 concentrations are raised by long-term metformin treatment in LBW/catch-up girls with precociou...

Background: Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes (T1DM). Although dehydration and electrolyte imbalance can be present in patients with DKA and T1DM, gastrointestinal tract complication remains unusual, especially in children. We report a child case of newly onset T1DM who developed acute ischemic intestinal necrosis with severe DKA combined with hypernatremic hyperosmolarity.Case re...

Background: Type 1 diabetes (T1D) is one of the most common chronic diseases in childhood and adolescence. Diabetic ketoacidosis (DKA) and severe hypoglycemia are complications of T1D and are associated with significant morbidity and mortality.Objective and hypotheses: The aim of this study was to determine the prevalence of acute metabolic complications in children with T1D admitted to the children hospital in Qazvin during 2005–2014.<p class="...

Background: There is high prevalence of Vitamin D deficiency (VDD) in Hashimoto’s thyroiditis (HT) as reported in literature. However, it is uncertain whether VDD is a cause or effect of HT. The effect L-thyroxine replacement on vitamin D levels in children with HT has not been studied.Objective and hypotheses: To study vitamin D level of newly diagnosed children with HT and to observe the change in vitamin D level after L-thyroxine therapy.<p c...

Background: Autoimmune polyglandular syndrome type 1 (APS1) is a monogenic autoimmune disease caused by defects in autoimmune regulator gene (AIRE). The classic clinical triad is composed of Addison disease, hypoparathyroidism, and chronic mucocutaneous candidiasis, however other endocrine and non-endocrine features of APS1 may occur.Objective: To describe an unusual clinical manifestation of APS1.Methods: Congenital lipodystrophy ...

Background: 5α-reductase-deficiency is an autosomal recessive disorder with clinical spectrum ranges from a male phenotype with hypospadias to a female phenotype. Many different mutations of SRD5A2 gene has been described in affected patients and clinical signs can vary depending on the degree of enzyme deficiency.Case presentation: 14-years-old girl admitted to our clinic because of feeling as a boy since 8-years-old. Parents were first degree cous...

Objectives: To discuss all challenges involved with providing children (including the very young) and adolescents with diabetes (CwD) with the latest appropriate technology, such as automated insulin delivery systems (AIDs), to manage their blood glucose and help improve their quality of life and suggest ways in which access to new types of devices available to adults can be improved for children with T1D.Methods: In con...

Background: The International Congenital Adrenal Hyperplasia (CAH) Registry provides rich longitudinal data from CAH patients with 21 Hydroxylase deficiency. We estimated the average total causal effect of fludrocortisone on blood pressure in patients with CAH by modelling within a causal inference framework.Methods: We constructed a directed acyclic graph (DAG) with domain experts (using Dagitty.net) to establi...

Objectives: To evaluate the effect of combined treatment with GnRH analogue (GnRHa) and recombinant human GH (rhGH) on the linear growth in mid/late pubertal girls at great bone ages with central precocious puberty (CPP) or early and fast puberty (EFP). To investigate the relation between C-type natriuretic peptide (CNP) signaling pathway and GH’s effect on linear growth in these girls. Methods 22 girls were diagnosed as CPP or EFP, whose bone ages were older than 11.5 ye...
