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...

Central precocious puberty (CPP) in girls is a diagnosis increasingly made by the Pediatric Endocrinologists worldwide. Although it is most frequently of idiopathic origin, magnetic resonance imaging (MRI) of the brain is recommended to rule out organic lesions causing CPP. However, controversy exists regarding the age limits for routinely performing MRI in girls with CPP.Objective: To evaluate the outcome of brain MRI in girls diagnosed...

Context: Type 1A pseudohypoparathyroidism (PHP-1A) is characterized by target organ resistance to PTH and Albright’s hereditary osteodystrophy (AHO). Basal ganglia calcifications and subcutaneous ossifications can be seen in PHP-1A. Acetazolamide, a carbonic anhydrase inhibitor, causes metabolic acidosis by increasing bicarbonate excretion from the proximal renal tubule thereby diminish precipitation of calcium and phosphorus. Acetazolamide had been used ...

Background: Primary hypoparathyroidism (HP) is a rare disease characterized by hypocalcemia, hyperphosphatemia and low/inappropriately normal parathyroid hormone (PTH) levels. We aim to characterize the clinical findings and molecular aetiology of childhood HP in our cohort.Method: DiGeorge-VCFS FISH analysis was performed on all patients (n=28) as the initial step after the diagnosis. In whom, FISH analysis was...

Background and Aim: Cystic fibrosis-related diabetes (CFRD) is a common extrapulmonary comorbidity in patients with cystic fibrosis (CF). Since CFRD is clinically silent in the early period, it is recommended to evaluate glucose metabolism with an oral glucose tolerance test (OGTT) annually in CF patients aged 10 years and older. Insulin therapy is thought to improve lung function and nutritional status in patients with CFRD. In this study, we aimed to evaluat...
