Genotype-Phenotype Correlations in 30 Japanese Patients With Congenital Hypothyroidism Attributable to TG Defects.

Context: Thyroglobulin (Tg), encoded by TG, is essential for thyroid hormone synthesis. TG defects result in congenital hypothyroidism (CH). Most reported patients were born before the introduction of newborn screening (NBS).

A Case of Salt-Wasting 21-Hydroxylase Deficiency With Resistance to Aldosterone due to Urinary Tract Infection.

Classic salt-wasting 21-hydroxylase deficiency (21-OHD) often requires fludrocortisone (FC) replacement. However, the optimal dose of FC varies between patients and the dose needs to be adjusted depending on the degree of symptoms. Further, the aldosterone resistance due to urinary tract infections causes salt-wasting symptoms.

High-fat diet accelerates extreme obesity with hyperphagia in female heterozygous Mecp2-null mice.

Rett syndrome (RTT) is an X-linked neurodevelopmental disorder caused by mutation of the methyl-CpG-binding protein 2 (MECP2) gene. Although RTT has been associated with obesity, the underlying mechanism has not yet been elucidated. In this study, female heterozygous Mecp2-null mice (Mecp2+/- mice), a model of RTT, were fed a normal chow diet or high-fat diet (HFD), and the changes in molecular signaling pathways were investigated.

Decrement in bone mineral density after parathyroidectomy in a pediatric patient with primary hyperparathyroidism.

Primary hyperparathyroidism (PHT) causes increased bone turnover, leading to reduction in bone mineral density (BMD). Parathyroidectomy is a definitive therapy and improves BMD in adult patients with PHT. However, there are no reports regarding alterations of BMD in pediatric or adolescent patients with PHT.

Erythropoietin (EPO) ameliorates obesity and glucose homeostasis by promoting thermogenesis and endocrine function of classical brown adipose tissue (BAT) in diet-induced obese mice.

Erythropoietin (EPO), clinically used as a hematopoietic drug, has received much attention due to its nonhematopoietic effects. EPO reportedly has beneficial effects on obesity and diabetes mellitus. We investigated whether interscapular brown adipose tissue (iBAT: main part of classical BAT) could play a role in EPO's anti-obesity and anti-diabetic effects in diet-induced obese mice.
