Background: Thyroid cancer before 20 years of age constitutes less than 2% of thyroid malignancies. Adult guidelines have been used in evaluation and follow-up of children until 2015. Features and long-term results of more children with PTC are needed to improve the ATA guideline for children. The aim of this study is to evaluate children with PTC in the last 15 years in a single reference-center, and assess the convenience of ATA 2015 guideline in practice.</...

Objective: Hereditary hypophosphatemic rickets is a rare renal phosphate wasting disorder causing burden on pediatric patients despite conventional treatment of phosphate and calcitriol. The aim of this study is to analyze genetic and clinical variability of children with X-linked hypophosphatemic rickets (XLHR), focusing on short term, long term and pubertal impact of conventional treatment. Design: Retrospective cohort studyMet...

Background: Premature adrenarche (PA) is characterized by an advanced bone age (BA) relative to chronological age (CA); nevertheless, clinical importance of this is not entirely understood. Literature contains few data on the impact of increased BA on adult height (AH) in PA. Objective of this study is to assess AH in girls with PA, and factors influencing AH.Methods: Retrospective analysis was carried out on 477 girls w...

Background: Subclinical hypothyroidism is defined as elevated TSH levels while T4 or FT4 levels are normal. Elevated TSH levels are linked with obesity in adults. In a recent meta-analysis in Iran, 6.1% of children below 18 had obesity. Due to the low number of studies on the subject in children we, designed the study to assess the relation between BMI Z-score and TSH levels in children and adolescence.Method: This c...

Introduction: Autoimmune polyendocrinopathy type 1 (APECED) is an autosomal recessive disease caused by loss of function mutations of autoimmune regulatory (AIRE) gene. Characteristically, early onset ectodermal dysplasia, mucocutaneus candidiasis is followed by hypoparathyroidism and primary adrenal insufficiency usually within the first two decades. Although clinical features may be variable, recently, it is suggested that population characteristics and natu...

Calcineurin inhibitors (CNIs) are widely used in pediatric transplantation for prevention of graft rejection, prophylaxis and treatment of graft versus host disease. Though hyperkalemia is a common adverse effect (10-45%), alterations in renin-angiotensin-aldosterone system in CNI-induced hyperkalemia are not well elucidated. Consequently, CNIs vital to transplantation are usually switched. Here, we describe two cases with CNI-induced hyperkalemia due to hyporeninemic hypoaldo...

Introduction: This study evaluated the postnatal growth of infants born with extremely low birth weight (ELBW) < 1 kg for 3 years.Method: Anthropometric measures (z scores) from birth, 2,4.6,12,18,24, and 36 months were measured in 87 randomly selected infants who were born with a birth weight below 1 kg (9-2016: 9-2018). Their growth data were compared to standard growth for normal age and sex using WHO growth standa...

Cafe au-lait skin macules, Cushing syndrome (CS), hyperthyroidism, liver and cardiac dysfunction have been described as presenting features of neonatal McCune Albright Syndrome (MAS). Despite being defined, neonatal diabetes mellitus due to hypercortisolism is a rare presenting feature. Outcome of patients presenting in neonatal period is usually unfavorable, tthough spontaneous resolution of hypercortisolism have been reported. Newborn girl was born at 38 weeks of gestation v...

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...

Background: Endocrine-disruptor compounds (EDCs) like phthalates and bisphenol A (BPA) can have long term effect on children's physical growth. Studies have reported that effect of EDCs exposure on concurrent physical parameters like weight. But there is a knowledge gap with regards to long term effects of EDCs exposure on children's physical growth. Thus, in this study we evaluated the prenatal exposure of EDCs: BPA and phthalates and their influence ...
