Background: Hyperinsulinism is a common cause of persistent hypoglycaemia in infant. Insulin secretion from pancreatic β-cells is unregulated and inappropriate for the level of blood glucose, causing glucose into the insulin-sensitive tissues, such as the muscle, liver and adipose tissue, leading to hyperinsulinaemic hypoglycaemia. But congenital portosystemic shunt, a rare vascular malformation, can cause hyperinsulinaemic hypoglycaemia rarely because glucose from portal...

Introduction: 5-α-Reductase type 2 deficiency (5αRD2) is 46,XY disorder of sex development that requires androgen treatment for normal male external genitalia development. Despite concerns regarding precocious puberty and stunted growth associated with androgen treatment, limited research has been conducted on its effects on individuals with 5αRD2. The present study aims to evaluate the impact of androgen treatment on bone age (BA) and height...

Hypophosphatasia (HPP) is a genetic skeletal disease caused by loss-of-function mutations of ALPL encoding tissue-nonspecific alkaline phosphatase (TNSALP). The clinical presentation of HPP varies greatly, ranging from stillbirth without bone mineralization to findings in later life, such as delayed walking, short stature, skeletal deformities, bone pain, and pathologic fractures. The diagnosis is based on clinical examination, radiographic findings, biochemical parameters of ...

Hypochondroplasia (HCH) is an autosomal dominant inherited skeletal dysplasia with abnormal growth pattern and inadequate pubertal growth spurt. Achondroplasia and HCH have many similar phenotype, however, HCH show the mildest phenotype among FGFR3-associated skeletal dysplasia, and the radiologic findings are usually so subtle. We investigated to evaluate clue for the hypochondroplasia, and clinical and genetic characteristics of eleven Korean patients with HCH. We a...

Background: Glycogen storage disease (GSD) is an inherited metabolic defect of metabolic defect of glycogenolysis and gluconeogenesis. Patients with GSDs are associated with endocrine abnormalities such as short stature, delayed puberty, fasting hypoglycemia, and dyslipidemia. In addition, patients with GSD 1b are also at risk of autoimmune hypothyroidism. Therefore, this study was performed to investigate endocrine complications in patients with GSD.<p cl...

Purpose: We investigated the difference of body mass index (BMI) score before and after gonadotropin-releasing hormone agonist (GnRHa) treatment in central precocious puberty girls (CPP).Methods: Medical records of 188 girls with CPP treated with GnRHa were reviewed. All patients completed the therapy. The patients were categorized into two groups according to initial BMI; normal weight group (BMI < 85 percentile) an...

Purpose: Growth hormone (GH) treatment has become common practice in Turner syndrome (TS) to improve final adult height. However, there are only a few studies on the analysis of good responders to GH treatment in TS. The aim of this study is to predict the responsiveness to growth hormone therapy in Turner syndrome.Methods: Among 197 TS patients registered in LG Growth study, 92 patients were excluded because of systemic illness or hypothyroidism. The cl...

Purpose: Patients with mixed gonadal dysgenesis (MGD) and ovotesticular disorders of sex development (DSD) usually present with asymmetric gonads. Differential diagnosis of these conditions is based on karyotype and pathological findings of gonads. However, it is difficult to determine sex of rearing and to predict long-term outcomes. This study investigated the clinical features, karyotype, sex of rearing, and pubertal outcomes of patients with MGD and ovotesticular DSD.<...

Background: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by a defect in cortisol biosynthesis. The most common form of CAH is the 21-hydroxylase deficiency (21-OHD), however, the incidence and the etiologic spectrum of other forms of CAH were not reported.Objective and hypotheses: This study describes the etiological distribution and clinical characteristics of CAH in a single academic centre.<p class...

Background: Pseudohypoparathyroidism (PHP) is a heterogeneous group of disorders characterized by hypocalcemia, hyperphosphataemia and Albright hereditary osteodystrophy (AHO), resulting from abnormalities of GNAS.Objective and hypotheses: This study investigated clinical features, outcomes, molecular characteristics of patients with PHP and pseudopseudohypoparathyroidism (PPHP).Method: Thirty one patients (15 males and 16...
