Background: The MC2R gene (MC2R) encodes the receptor for ACTH, and MC2R mutations cause ACTH resistance. We describe a MC2R mutation-carrying ACTH resistance patient, who exhibited generalized hyperpigmentation at birth.Objective and hypotheses: The MC2R encodes the receptor for ACTH, and MC2R mutations cause ACTH resistance. We describe a MC2R mutation-carrying ACTH resistance patient, who exhibited generalised hyperpigmentat...

Background: Lipoid congenital adrenal hyperplasia (LCAH) is caused by mutations in STAR and characterized by defect in adrenal and gonadal steroidogenesis and lipid droplet accumulation in steroidogenic cells. 46,XY patients with classic LCAH typically present with female-type external genitalia, while those with nonclassic LCAH have masculinized external genitalia. The rarity of the nonclassic form precludes the clarification of pubertal and reproduc...

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...

Case: An 8-year-old boy with Down syndrome. He was born at 36 week of gestation, birth weight was 1668 g (-2.5 SD). He complicated transient hyperinsulinemia (THI) treated with diazoxide for 2 months and hypothyroidism continuing treatment with levothyroxine. He was not detected transient abnormal myelopoiesis at neonatal period. He was diagnosed with precursor B-cell acute lymphoblastic leukemia (ALL) at age 8 years and started chemotherapy with a steroid, an...

Background: The metabolic outcome in adult life is known to be determined during fetal life. Prenatal poor nutrition also affects growth and maturation, formation of insulin resistance during childhood. Little is known about the effect of maternal gestational diabetes mellitus (GDM) on early metabolic and growth outcome of their children.Objective and hypotheses: To investigate growth, glucose metabolism, and blood pressure in children of mothers with GD...

Background: In Japan, diabetic screening for school children using urinalysis has been performed to detect diabetes mellitus during childhood throughout the country. However, inadequate follow-up system after urinary screening caused several problems. The rate of participation in workup examination still remains less than 30%. Also, accurate annual incidences of children with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) detected by screening of urine glu...
