Introduction: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders of the steroid biosynthesis. 21-hydroxylase deficiency (21-OHD) represents 90–95% of CAH patients and causes adrenal insufficiency and virilization. Although most patients are diagnosed in childhood, the diagnosis of some classical CAH cases are extremely delayed up to sixth and seventh decades of life. Herein, we report a 46, XX patient with 21-OHD diagnose...

Introduction: Increasing incidence of male reproductive disorders may be due to fetal exposure to putative endocrine disruptor chemicals (EDCs), such as phthalates and phenols. Anogenital Distance (AGD) is a biomarker of fetal androgen action in animals, and has recently been linked to testicular dysgenesis syndrome in humans.Objective: To examine the relationship between prenatal phthalate and phenol exposure and birth AGD in male infants.<p class="...

Background: Glucose monitoring is vital in children with persistent hypoglycaemia to reduce the risk of adverse neuro-behavioural outcomes1. Continuous glucose monitoring (CGM) systems provide real-time glucose levels however; information on its usefulness in monitoring glucose levels in this cohort is limited2, 3.Objective: To ascertain the effectiveness of CGM and to evaluate parents’ experie...

Background: GH insensitivity is caused by disturbances of GH receptor function or inability to transduce the hormone signal. Affected children are severely growth retarded and may also present immune complications when the transducer STAT5B is defective. Only autosomal-recessive STAT5B mutations have been described to date.Clinical case: Two male 14.5 year monozygotic twins presented with heights of 131.5 cm (−5.3 SDS). Bone age of the ind...

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: Osteogenesis imperfecta (OI) is a genetic disorder characterized by diffuse osteoporosis, recurrent fractures, and resulting deformities. Bruck syndrome (BS) is a rare autosomal recessive disease that manifests with many symptoms of OI. In addition to the deficiency of type I collagen in OI, congenital joint contractures also occur in BS. BS is caused by mutations of FKBP10 (BS type 1) and PLOD2 (BS type 2) genes encoding the chaperone-collagen com...

Introduction: SHOX deficiency is the most common cause of monogenic short stature and results in short stature with a highly variable phenotype. In this study, we aimed to detect SHOX gene pathologies in patients who applied to the pediatric endocrine outpatient clinic with short stature and who were found to have Madelung deformity on hand-wrist radiography, and to evaluate the clinical, laboratory features and responses to growth hormone (GH) treatment.<...
