Objective: In the present study, it was aimed to investigate the concomitance of additional cardiac problems, mainly mitral valve prolapse, in adolescents and pediatric patients with Hashimoto’s thyroiditis, by screening autoimmune markers.Methods: Euthyroid 57 patients, who applied to the Pediatric Endocrinology clinic at our institution with marked symptoms of hypothyroidism at the time of diagnosis, and were diagnosed and treated for Hashimoto&#1...

Background: 5α-Reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT) in peripheral tissues. DHT is responsible for the differentiation of male external genitalia. Mutations in the 5α-steroid reductase type 2 gene (SRD5A2) result in incomplete masculinisation of the external genitalia in subjects with a 46,XY karyotype. The clinical spectrum of a 46,XY individual with 5α-reductase deficiency at birth can range from complete femal...

Background: Thrombocyte volume parameters such as mean thrombocyte volume (MPV) and PDW (thrombocyte distribution volume) are parameters used in evaluation of thrombocyte size which have hemostatic importance. The increased thrombocyte volume is a marker of thrombocyte activation. The thrombocyte activity is important in pathophysiology of diseases with a tendency of thrombosis and inflammation. In adult studies it has been reported that MPV increases in thrombotic diseases su...

Background: Local oestrogen production in the brain regulates critical functions including neuronal development, gonadotropin secretion and sexual behaviour. In the mouse brain, a 36 kb distal promoter (l.f) regulates the Cyp19a1 gene that encodes aromatase, the key enzyme for oestrogen biosynthesis. In vitro, promoter l.f interacts with oestrogen receptor alpha (Esr1) and Progesterone receptor (Pgr) to mediate Cyp19a1 mRNA expressi...

Background: An optimal vitamin D status is important for the growth and development of bones in children and adolescents. The prevalence of vitamin D deficiency is still high, even in low-latitude and industrialized countries, and vitamin D deficiency in childhood is reemerging as major public health issue.Objectives: To determine the frequencies of 25-hydroxyvitamin D (25(OH)D) deficiency and insufficiency in children and adolescents.<p class="abste...

Introduction: Brain-lung-thyroid syndrome (BATS) is a rare autosomal dominant inherited syndrome that develops due to mutations in the NKX2-1 gene, which is a thyroid transcription factor, and is characterized by respiratory distress in the neonatal period, congenital hypothyroidism, and choreatetosis. Approximately half of affected patients have the complete triad, with 30% affected by the neurological phenotype (motor developmental delay, gait difficulties, choreatetosis, hy...

Background: Mutations in the nicotinamide nucleotide transhydrogenase (NNT) gene are a rare cause of primary adrenal insufficiency (PAI), as well as cardiomyopathies and functional impairment of the gonads.Objective: Despite the description of different NNT mutations in homozygosis and compound heterozygosis in PAI patients, it remains to be clarified to which extent the function and expression of the m...

Background and hypothesis: Mitochondrial disorders are multisystemic conditions associated with sensorineural hearing loss, encephalomyopathy, lactic acidosis, and non-autoimmune diabetes. The majority of molecular etiologies involve mutations in the genes encoding the oxidative phosphorylation system's components. Superoxide generation is significantly increased and causes oxidative damage in the affected tissues in these disorders. The establishment of ...

Introduction: Ovarian torsion (OT) occurs with partial or complete obstruction of blood flow as a result of rotation of the ovary around the infundibulopelvic ligament and/or utero-ovarian ligament. OT is very rare in the pediatric population. Although the most common form of presentation is abdominal pain, the unclear symptom profile in children can often result in missed diagnosis or late diagnosis. For the preservation of ovarian functions and future fertil...

Background: In adult studies, serum uric acid level (SUA) has been shown to be associated with cardiometabolic anomalies of metabolic syndrome such as insulin resistance, hypertension, increased carotid intima thickness, and hyperuricemia is considered as an independent risk factor for atherosclerosis and cardiovascular disease. Early cardiovascular changes in obese children and studies on the relationship between metabolic syndrome and hyperuricemia are quite...
