Backround: Hereditary inborn errors of thyroid hormone synthesis account for 10-15% of congenital hypothyroidism (CH). Thyroid peroxidase (TPO) deficiency is the most common enzymatic defect with a frequency of 50-90%.Aim: In the present study our objective was to characterize the long-term clinical outcome in patients with TPO deficiency and to assess the association between development of multinodular goiter (M...

Background: A high rate of hearing impairment has been reported in patients with congenital hypothyroidism (CH). However, this association has only been explored in a few studies with inconclusive findings.Objectives: To assess the prevalence of hearing impairment among patients with CH and determine whether hearing impairment is related to delay in supplemental therapy, etiology of CH or other parameters.Methods: Audiometry was un...

Homozygous loss-of-function mutations of the calcium-sensing receptor gene (CaSR) are associated with neonatal severe hyperparathyroidism (NSHPT), a life-threatening condition with a challenging treatment approach.We report a 7-day-old-female infant who was admitted to our Pediatric Department due to poor sucking. On examination she was lethargic and hypotonic. Laboratory evaluation revealed extreme hypercalcemia of 23.54 mg/dL (N: 7.6–10.4...

Background: Disorders of sex development (DSD) are classified as a congenital discrepancy between external genitalia, and gonadal and chromosomal sex. Despite extensive laboratory and imaging investigations, the etiology of DSD is unknown in more than 50% of patients. We aimed to evaluate the etiology of DSD using whole exome sequencing (WES) technique.Methods: Eleven patients with DSD (ten with 46,XY and one with 46...

Background: Neonatal hyperthyrotropinaemia (HT) is defined by elevated thyroid stimulating hormone (TSH) and normal free-thyroxine (FT4) level. Persistent HT in the neonatal period is often a diagnostic dilemma for clinicians to either treat to prevent subclinical hypothyroidism or to wait and monitor thyroid function tests (TFTs).Methods: As part of an audit, 1,449 term infants who had TFTs undertaken as part of a prolo...

Background: Patients with TS frequently demonstrate impairments in social cognition difficulties, visual-spatial processing, face and emotion perception.Objective and hypotheses: We examined face perception in the context of perceptual visual dysfunctions and social cognition skills in TS.Method: 26 young women with TS on estrogen replacement therapy, and 26 control participants. They were tested on various cognitive and psychologi...

Background: Primary care pediatricians (PCPs) use thyroid function tests (TFT) as screening tests in children and adolescents with various health complaints. Thus, it is crucial to evaluate the results according to appropriate cut-offs individualized to the child characteristics. Such references values, which are missing in the pediatric age group, are needed for proper evaluation of the thyroid functions.Objective and hypotheses: To determine normal TSH...

Background and aims: Achieving good glycemic control is a major challenge for adolescents with type 1 diabetes (TID). The introduction of the MiniMed 780G system, an advanced hybrid closed-loop (AHCL), that enables an automatic correction of insulin, gave hope for improved glycemic outcomes in adolescents. We assessed specific characteristics associated with glycemic measures in youth with T1D switching to Minimed 780G.Methods:</...

Background: Type 1 Diabetes (T1D) is a chronic disease resulting from autoimmune destruction of insulin-secreting pancreatic β cells. Viruses are known to play a role in the pathogenesis of T1D. There is no consistent evidence that SARS-CoV-2 induces T1D in children or adults. Nevertheless, evidence suggests that the SARS-CoV-2 affects β cell function, suggesting a role for the virus in the pathogenesis of the disease. It is thus plausible that the e...

Shox gene deficiency which causes short stature is a known indication for treatment with growth hormone. The prevalence of shox deficiency among children with idiopathic short stature has a high variability in different studies and ranges between 1.5-17%. We aimed to determine the incidence of SHOX haploinsufficiency in our region and to assess the genotype-phenotype relation which may help with setting criteria in the decision to which patients should we offer this genetic te...
