Background: Patients with homozygous and compound heterozygous familial hypercholesterolemia (FH) have markedly elevated plasma LDL cholesterol (LDL-C) from birth. If untreated, patients develop cardiovascular atherosclerosis resulting in death before the second decade of life. Medication and apheresis are only partially effective in reducing LDL-C levels, and do not significantly improve the prognosis. Liver transplantation (LT) can nearly normalize the cholesterol metabolism...

Background: Late preterm birth (defined as infants born between 34 and 36 weeks of gestational age) is increasing worldwide. Their postnatal growth has not been fully investigated.Objective and hypotheses: To identify the characteristics of postnatal growth and biochemical markers in late preterm infants.Method: Among 2014 children in the birth cohort study conducted from 2010, 51 children were born late preterm with birth weight a...

Background: Childhood obesity starts in early childhood. The natural history of childhood obesity has not been reported and it is unknown how obese children in early childhood improve to become non-obese adolescents.Objective and hypotheses: To investigate the natural history of obese children from early childhood to puberty and identify patterns and trends in this process.Method: 1207 children (614 boys and 593 girls) born in Fuji...

Background: Pituitary abscess is a rare disorder, representing less than 1% of pituitary lesions. Preoperative diagnosis is often difficult due to non-specific symptoms and image findings.Case Report: Here, we report the case of a 10-year-old girl with a pituitary abscess. She presented with polyuria and polydipsia and headache for the past year. Magnetic resonance imaging revealed polycystic lesion in the sella turcica ...

Background: Progeria syndromes caused by LMNA gene variants consist of Hutchinson-Gilford progeria syndrome (HGPS) and Atypical progeroid syndrome (APS). Various phenotypes of APS are previously reported, whereas HGPS shows relatively unique phenotype.Objective: To investigate the spectrum of clinical manifestations in three cases of Progeria syndrome.Methods: The history ...

Abnormal expression of imprinted genes leads to imprinting disorders (IDs). Silver-Russell syndrome (SRS) and Prader-Willi syndrome (PWS) are representative IDs showing small for gestational age and short stature (SGA-SS).Temple syndrome (TS14) caused by abnormal gene expression at the 14q32.2 imprinted region, maternal uniparental disomy of chromosome 6 (UPD(6)mat), 16 (UPD(16)mat), and 20 (UPD(20)mat) are also associated with SGA-SS. Fuethermore, some copy number variations ...

Background: Wiedemann–Steiner syndrome (WSS) is a rare autosomal dominant disorder characterized with hypertrichosis cubiti, dysmorphic facial appearance (hypertelorism, thick eyebrows, and narrow palpebral fissures), psychomotor delay, and short stature. WSS is caused by a mutation in the KMT2A gene. The timing of secondary sexual characteristics in patients with WSS is not well known. To our knowledge, two patients (one boy and one girl) with W...

Background: Partial Androgen Insensitivity Syndrome (PAIS) is characterized by varying degrees of masculinization defects due to impaired androgen action, resulting in a wide range of physical and psychological phenotypes.Case 1: 18-year-old with a male social gender. The patient presented with hypospadias, micropenis, and cryptorchidism during the neonatal period, and received testosterone therapy during infancy, but sh...

Background: Maternal uniparental disomy of chromosome 16 (UPD(16)mat) is defined as the presence of two homologous chromosomes 16 inherited from only the mother. To our knowledge, 49 live-born UPD(16)mat patients without chromosomal abnormalities other than that in chromosome 16 have been reported. UPD(16)mat patients presented with non-specific clinical features such as preterm birth, growth retardation, congenital heart diseases (CHDs) and hypospadias. Silver-Russell syndrom...

Background: Abdominal fat distributions are reportedly strongly associated with metabolic risks in type 2 diabetes mellitus. However, research on fat distribution in adolescents with type 2 diabetes mellitus has been limited.Aim: To investigate fat distribution characteristics in adolescents with type 2 diabetes mellitus for comparison to those with simple obesity in Japan.Design/Methods</s...
