Introduction: The Sonic hedgehog (SHH) signaling pathway plays a crucial role in development of the forebrain and pituitary. Mutations in SHH signaling related genes are well known to be the cause of Holoprosencephaly (HPE), which results from developmental field defect or impaired midline cleavage of the embryonic forebrain, and is frequently associated with hypopituitarism. This study aimed to define the prevalence of congenital hypopituitarism (CH) in terms...

Introduction: Wolfram syndrome (WS) is a rare progressive neurodegenerative disease that shows autosomal recessive inheritance characterized by diabetes insipidus, diabetes mellitus (DM), optic nerve atrophy and deafness. WFS1 gene encoding a protein, wolframin, which is essential to the function of the endoplasmic reticulum, is identified as main causative gene of the disease. We report here a sibling case suspected WS with insulin-dependent DM and optic atrophy in early chil...

Background: Achondroplasia is the most common form of human short-limbed dwarfism. The most serious complication in individuals with achondroplasia is narrowing of foramen magnum (FM) that results in cervicomedullary compression and sudden infant death. To avoid sudden infant death, early monitoring and implementation of the necessary medical intervention are important. However, the optimal method of screening for cervicomedullary compression continues to be debated.<p cla...

Background: Hashimoto thyroiditis (HT) is characterized by autoimmune-mediated destruction of the thyroid gland. Ca metabolism disturbance due to hypoparathyroidism among HT patients remains to be clarified.Objective: To clarify the relationship between HT and primary hypoparathyroidism.Patients and Methods: Serum levels of Ca, albumin, and whole PTH (wPTH, ECLIA) were measured in ...

Background: Adrenal hypoplasia congenita (AHC) is a rare disorder with an estimated frequency of 1 case per 12,500 live births. AHC causes 46,XY disorders in sex development (DSD) due to adrenal androgen deficiency.Objective: Case report ona male AHC patient with no external genitalia abnormalities.Case report: The baby was born at 37 weeks'gestation with a height of 46.5 cm (-...

Background: Septo-optic dysplasia (SOD) is a rare disorder characterized by optic nerve hypoplasia, anterior midline abnormality and pituitary hormone deficiency. Mutations of several genes are known to cause SOD related condition, such as HESX1, SOX2, SOX3, and OTX2, but mutations of WDR11 has not been reported in SOD.Objective: Reporting the first SOD patient identified a mutation in WDR11.<p cl...

Background: While existing guidelines recommend long-term follow-up of childhood cancer survivors (CCS), their fertility has not been clarified in Japan.Objective and hypotheses: To address this issue, we organized a working panel to compile evidence from CCSs. The team consisted of various medical specialists in foundation hospitals.Method: We had conducted the questionnaire surveys targeting pediatric endocrinologists regarding r...

Cytochrome P450 oxidoreductase deficiency (PORD) is a disorder of steroidogenesis that causes various symptoms such as skeletal malformations, disorders of sex development, and adrenal insufficiency. The aim of this study was to elucidate the clinical characteristics, especially age at diagnosis and treatment, of PORD from the perinatal period to adulthood in Japan. The first questionnaire was sent to 183 council members of the Japanese Society for Pediatric Endocrinology on 1...
