Aim and Method: Diagnosis of type 1 diabetes (T1DM) may be delayed in some children, despite seeking medical care by the family. In this prospective/observational study, the time and process from consulting with a doctor to getting diagnosed with diabetes was investigated in patients hospitalized for newly diagnosed T1DM between 2021-2022.Results: During the study period total of 114 newly diagnosed T1DM patients (49%F, ...

Donohue syndrome(DS) is a rare and often lethal autosomal recessive disease. Its prevalence is estimated less than one in a million live births. Mutations in the insulin reseptor (INSR) gene cause rare severe INSR-related insulin resistance syndromes such as DS. It is characterized by severe insulin resistance (hyperinsulinemia, fasting hypoglycemia and postprandial hyperglycemia), intrauterine and postnatal growth retardation, hypotonia, organomegaly including heart, liver, k...

Background: Bronchiectasis is a result of recurrent pulmonary infections and chronic inflammation.Objective and hypotheses: Chronic inflammation may lead some endocrinological disorders. The consequences of the bronchiectasis on the endocrinological system and on the bone health in childhood were investigated in this study.Method: The medical records of the 64 children with bronchiectasis (32 females and 32 males) at the mean age o...

Background: Hereditary 1,25-dihydroxyvitamin D resistant rickets (HVDRR) caused by vitamin D defective receptor.Objective and hypotheses: We performed VDR gene analysis four patients with alopecia, skeletal dysplasia, and hypocalcaemia.Method: Genomic DNA extracted from peripheric blood. Whole gene sequence analysis was performed.Results: We found homozigot p.Q152* (c.454G>T) mutation three patients. Two ...

Context: Assessment of breast development by physical examination(PE) can be difficult especially in overweight girls and in early stages. We aimed to study ultrasonography(USG) on evaluation of breast tissue in girls with breast development< 8 years of age.Patients and Methods: In this prospective study, 125 girls (age 7.1&pm;1.5 years) with early breast development were evaluated by breast USG for ultrasonographic b...

Background: Hereditary hypophosphatemia (HH), is a rare condition related to decreased renal tubular phosphate reabsorption. Although X-linked hypophosphatemia (PHEX mutation) is the most frequent cause of HH, recent advances in the next-generation sequencing (NGS) techniques enable the identification of various genetic etiologies. Our study aims to determine the molecular etiology of patients with hypophosphatemia and to identify new candidate genes....

A worldwide increase in pediatric thyroid cancers incidence over the years has been observed. Although pediatric thyroid cancers tend to have a more aggressive course compared to adults, the survival rate is better. In this study, we aimed to examine the demographic, clinical, pathological, and laboratory characteristics, prognostic and risk factors of children with thyroid cancer.Methods: We retrospectively analyzed 39 children with thy...

Context: The 45,X/46,XY mosaicism poses a great clinical challenge influencing gonadal development, histology, hormonal balance, and growth. Patients present a wide spectrum of phenotypes with varying degrees of genital ambiguity from Turner Syndrome to male. Here, we present five children with 45,X/46,XY mosaicism presenting with different clinical phenotypes.Case Descriptions:Case 1:</str...

Background: Hypersensitivity reactions to gonadotropin releasing hormone analogues (GnRHa) is a rare but serious side effect . Besides, local reactions, urticaria, anaphylaxis, serum disease, Henoch Schonlein Purpura (HSP) have been reported during GnRHa treatment.. Clinicians should be aware of the potential association of GnRHa with systemic hypersensitivity reactions.Case reports: Here, we report nine girls with syste...

Background: Vitamin D Dependent Rickets Type IA (VDDR-IA) is the most common type of VDDR and caused by mutations in CYP27B1. Here, we aimed to analyze the genotypic and phenotypic features of our VDDR-IA patients.Materials and Methods: The patients with a clinical diagnosis of VDDR-IA were enrolled and analyzed for CYP27B1 gene mutations.Results: 12 (5 males) pat...
