Background: Congenital hypothyroidism (CH) is divided into two main groups as ‘permanent’ and ‘transient’. Diagnosis of transient hypothyroidism is important to avoid lifelong unnecessary therapy with its possible side effects.Objective and hypotheses: We aimed to determine the rate of transient and permanent congenital hypothyroidism of the newborns referred to our clinic from the neonatal screening program in this study.</st...

Background: Various studies, mostly conducted in adults, evaluated the hormonal axis in primary empty sella (PES), and reported different forms of pituitary deficiencies. We report our 10-year experience of pediatric cases with PES, investigating the pituitary function, associated impairments, and responses to treatments.Materials and Methods: We reviewed 10,560 cranial and 325 pituitary magnetic resonance imagings (MRIs) performed in ou...

Background: Obesity is a multifactorial disease caused by environmental and genetic factors. Single gene defects explain approximately 5-13% of early-onset obesity and these rates vary according to genetic panel used and the rate of consanguinity in the population studied. As the new treatment modalities emerge for monogenic obesity, it is important to identify the molecular etiology of obesity.Materials and Methods: Buc...

Introduction: Metaphyseal dysplasia, Spahr type(MDST) is an autosomal recessive primary skeletal dysplasia characterized by postnatal short stature, progressive bowing deformity, waddling gait, with an incidence of <1/1 million. MDST is caused by mutations in Matrix metallopeptidase 13(MMP13) gene. The MMP13 plays a role in the degradation of extracellular matrix proteins. It is required for embryonic bone development and ossification. It may be involved in...

Introduction: Craniopharyngiomas can lead to pituitary insufficiency and long-term endocrine complications due to the location, invasive character and risk of recurrence, besides they known as histologically benign.Aim: In this study, we aimed to evaluate the demographic, clinical features, endocrinological problems and follow-up findings in patient with craniopharyngioma in childhood.Metho...

Background: Actual surgical procedures for the treatment of patients with VSD (Variation of Sex Development), in particular severe hypospadias, are associated with frequent post-operative complications.Objective and hypotheses: Tissue engineered collagen tubes are a promising alternative.Method: We elaborated a new, two layered, collagen based tube that can be sutured. Mechanical testing proved a better resistance of those tubes co...

Background: Inactivating mutations in the calcium sensing receptor (CASR) may result in disorders of calcium homeostasis manifesting as familial benign hypocalciuric hypercalcemia (FBHH) and neonatal severe hyperparathyroidsm (NSHPT).Objective and hypotheses: We report two cases with NSHPT together with their treatment and long-term follow-up.Method: Two cases were referred with severe hypercalcemia in the neonatal period....

Background: Proopiomelanocortin (POMC) deficiency is characterized by early-onset obesity, adrenal failure, red hair and pale skin. The first genetic mutation in the POMC gene was demonstrated in 1998. This disorder is rare, but has increased our insight into the important role of the leptin-melanocortin pathway in energy balance. POMC deficiency causes obesity due to the inadequate production of alpha and beta MSH from POMC, which normally activate the melanocortin 3 receptor...

Background: Variants in SH2B1 or a 220–kilobase pair distal deletion of chromosome 16p11.2, including SH2B1, are associated with severe, early-onset obesity and hyperphagia. The melanocortin-4 receptor (MC4R) agonist setmelanotide is being investigated in individuals with rare variants in genes in the MC4R pathway.Methods: This ongoing, Phase 2 study (NCT03013543) enrolled individuals aged ≥6...

Introduction: Primary osteoporosis (POP) is a rare and important problem in childhood that can cause serious skeletal deformities and morbidity. In this study, we aimed to reveal the spectrum of POP in childhood, and also to assess the effectiveness and safety of bisphosphonates in increasing BMD, reducing fractures, and improving quality of life.Method: Patients with POP and who received at least one course of pamidrona...
