Introduction: Gynecomastia is common in boys at early-mid puberty, while prepubertal gynecomastia is a rare condition. Sertoli cell tumors (SCTs) account for 2% of prepubertal testicular tumors. Most of the SCTs in prepubertal boys, which are generally bilateral and diffuse, are in the content of Peutz-Jeghers Syndrome (PJS) or other familial syndromes (Carney complex). Large cell calcifying Sertoli cell tumor (LCCSCT) is a variant of SCT and is seen in PJS. I...

Background: Rare genetic diseases of obesity can be caused by genetic variants leading to disrupted activity of the melanocortin-4 receptor pathway (MC4R). Setmelanotide, an MC4R agonist, is being investigated in a basket study of populations with rare variants in different genes in the MC4R pathway who have early-onset, severe obesity and hyperphagia.Methods: This ongoing, Phase 2, open-label study (NCT03013543) enrolle...

Keywords: children, primary osteoporosis, next-generation sequencingBackground: Primary osteoporosis (POP) is a rare bone fragility disorder of childhood and is mainly related to osteogenesis imperfecta (OI). However, patients without clinical OI features with recurrent long bone and/or vertebral fractures who comply with the osteoporosis criteria are considered to have non-OI POP. Diagnosis and classification of non-OI ...

Background: Next-generation sequencing (NGS) technologies have improved our knowledge about the genetic basis of congenital hypothyroidism (CH). The objective of our study was to evaluate the molecular genetic etiology in our primary CH cohort by using the NGS-based panel.Subjects and Methods: The clinical and genetic characteristics of 147 patients (61 female) from 129 unrelated families were evaluated. The patients wer...

Introduction: Euvolemic hyponatremia is a typical feature of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Excessive secretion of antidiuretic hormone (ADH) leads to activation of the type 2 vasopressin receptor (AVPR2) in the kidneys, which plays a role in concentrating urine. Etiologies of SIADH include cranial surgery, intracranial malignancy, meningitis-encephalitis, cerebral hemorrhage, other cerebral pathologies, pulmonary path...
