Congenital hyperinsulinemia occurs due to inappropriate insulin secretion from beta cells of the pancreas. It is the most common cause of resistant and recurrent hypoglycemia in neonates and infants and the threatment is very difficult. Although the incidence is reported as 1/50000, it is seen more frequently in consanguineous countries. Patients may present with lethargy, nourishment, irritability and seizures. If it is not treated, severe hypoglycemia may result in severe ne...

Objective: According to the etiology of hyperparathyroidism, it is divided into primer and secondary (uremic). It usually develops due to CaSR mutation in the infancy period. On the other hand, it usually emerges secondary to a parathyroid adenoma in adolescents. Parathyroid adenomas seen in childhood are commonly associated with familial multiple neoplasia syndromes (MEN). Patients may present with bone pain, proximal myopathy, fractures, renal stone, pancreatitis or they can...

Background: Type 2 diabetes is a heterogeneous disorder characterized by the defective of insulin, which can not progressively compensate for insulin resistance, due to the influence of environmental factors on the basis of genetic susceptibility. Hyperglycemia, which starts with insulin resistance, is thought to show toxic effects (glucotoxicity) on β cells and ultimately impairs beta cell function., Although many factors play a role in etiology, obesity is the most comm...

Background: 4p duplication syndrome is a very rare chromosomal disorder. In the literature; dysmorphic facial features, learning disability, speech retardation, overgrowth, musculoskeletal abnormalities, attention deficit hyperactivity disorder and autism syndrome have been reported to be associated with 4p16.3 duplication. Here we present a patient who admitted to our clinic with complaints of growth in hands and feet along with delayed speech and mental retardation. The gene...

Aim: Premature pubarche is defined as the start of axillary and pubic hair before age 9 in boys and 8 in girls. 10 times more common in girls than boys. Central precocious puberty is a condition due to early activation of hypothalamic-pituitary- gonadal axis associated with breast development before age 8 in girls and testicular volume growth before age 9 in boys. Despite this axle is not known exactly which hormones are respnsible for the activation, the role of kisspeptin&#1...

Background:In children and adolescents suffered form primary intracranial germ cell tumors, bifocal GCTs are rare and were reported a bad prognosis. In this study, we report a case and summarize the clinical characteristics and prognosis.Methods: A boy suffered form bifocal GCTs (Basal ganglia and pineal region) was diagnosed in our hospital and accepted chemotherapy+radiotherapy, and was followed up.<p class="abstex...

The DHX37 gene has been identified to cause 46, XY disorders of sex development (DSD), yet there are no reports in China. Here, we report a Chinese pediatric case of 46, XY DSD identified by Whole-exome sequencing which carried a heterozygous missense mutation c.2020 C > T (P.R674 W) in DHX37 gene (NM _ 032656) inherited from the mother. Gonadal pathology showed that the left gonad was structured with a vas deferens and epididymal duct, and the right gonad had vas deferens,...

Background: Insulin resistance in obesity and type 2 diabetes is associated with abnormalities in mitochondrial oxidative phosphorylation in skeletal muscle. Whether mitochondrial function changes in hepatocytes with hereditary insulin resistance is not clear. Type A Insulin Resistance Syndrome (TAIRS) is a rare disorder characterized by severe insulin resistance, a condition in which the body's tissues and organs do not respond properly to the hormone ins...

Objective: Thyroxine binding globulin (TBG) is the most important thyroid hormone transporter in humans and is encoded by the SERPINA7 gene located on chromosome Xq22.2. By analyzing the genes of TBG-deficient patients, we aim to find a new molecular basis for the possible etiology of the disease.Design and Methods: 10 groups of subjects were enrolled in the pediatric department of the First Affiliated Hospital of Zhejia...

Objective: We aim to investigate the association among progranulin (PGRN), high-mobility group box 1 (HMGB1), and obesity related markers in young rat model of high fat diet-induced obesity.Materials and Methods: 20 Male Sprague-Dawley (SD) rats at the age of 21 days were divided into two groups randomly. The rats were fed with normal diet (NC group) or high-fat diet (OB group). The NC group and OB group were sacrificed ...
