Langerhans cell histiocytosis (LCH) is a rare disorder of unknown etiology affecting the mononuclear phagocyte system. It is characterized by clonal uncontrolled proliferation and accumulation of immature dendritic cells in different organs. Affected cells express CD1-alpha and/or CD207 (Langerin) on immunohistochemistry. Although bone is the most commonly affected organ (80%), all other organs can be affected either alone or in combination. LCH is classified into Single syste...

Introduction: Polydipsia and polyuria are one of the common chief complaints in the field of pediatric endocrinology. The differential diagnosis of polydipsia and polyuria are various diseases including diabetes mellitus (DM), central diabetes insipidus (CDI), and primary polydipsia (PP). Although DM is not difficult to diagnose, between DI and PP is sometimes difficult.Aim: The objective of our study is to reveal the in...

Background: Polyuria and polydipsia syndrome (PPS) workup is not straightforward, especially in children. Basal investigations are often not reliable in distinguishing among diabetes insipidus (DI), central (CDI) or nephrogenic (NDI), and primary polydipsia (PP). Water deprivation test (WDT) is often essential, although uncomfortable and not always reliable enough to recognize partial DI. Plasma AVP investigation is not routinely used in the diagnostic pathway...

Background: Sea-blue histiocytosis is a morphological finding that can be associated both with acquired conditions of increased cellular turnover and inborn errors of lipid metabolism.Objective and hypotheses: To present a Chinese boy of hypertension and sea-blue histiocytosis secondary to Niemann–Pick disease type B.Methods: Diagnosis was confirmed by the bone marrow aspiration and the specific enzyme assay of leukocytes (def...

Introduction: The annual incidence of Langerhans cell histiocytosis (LCH) is 5 per million in admission with a diagnosis of isolated central diabetes insipidus (CDI) in children under the age of 15. Here, the process leading to the diagnosis of LCH at presentation with isolated CDI, imaging findings, and the sellar erosion, which has not been previously reported in the literature, will be discussed.Case presentation: A 4-year-5-month-old...

Introduction: Diabetes insipidus (DI) is a rare disease in children. In most cases it is acquired and central in origin (CDI). The most frequent cause of acquired CDI is brain tumor and idiopathic forms represent between 20-50% of cases, depending on the series. Autoimmune hypophysitis is a rare cause of DI and is a presumptive diagnosis with a suggestive brain MRI and ACTH and TSH deficiencies as the most common hormonal involvement, although it can manifest ...

Background: Childhood craniopharyngiomas are known to be associated with an increased risk of excessive weight gain and hypothalamic obesity. Atypical clinical manifestations include the development of a diencephalic syndrome (DS) with a failure to thrive or weight loss.Objective and hypotheses: In a retrospective study we analyzed 21 of 485 childhood craniopharyngioma patients (4.3%) who presented with a low weight (<−2 BMI SDS) at time of dia...

Background/aims: Obese girls experience precocious puberty which could influence their final height. We studied the effect of metformin on their body weight, final height, onset of menarche, and bone age.Methods: In a prospective study, 63 obese girls aged between 8 -13 years old were treated with metformin (500-1000 mg/daily and compared with control at the outpatient pediatric endocrine clinic of Loghman Hakim Hospital...

Background: Non-alcoholic fatty liver disease (NAFLD) is considered the hepatic manifestation of metabolic syndrome. Accelerated catch-up in weight during infancy in subjects born term has been associated with increased risk for NAFLD in adulthood, but this association has not been studied in subjects born preterm.Objective and hypotheses: To investigate the associations of birth weight, gain in weight for length and accelerated catch-up in weight in the...

Introduction: Placental hormones can control the transfer of maternal nutrients to the fetus and modulate fetal and neonatal growth. Data about the interaction between maternal, placental and fetal IGF1/IGFBP in relation to newborn size is not clear,Aim: To review research paper published in Pubmed, Google scholar, Research gate, and Scopus in the past 20 years on the relation between maternal, placental and fetal/infant...
