HESX1/Hesx1 is a member of the paired-like class of homeobox genes and is essential for pituitary and forebrain development. Mice with a targeted homozygous deletion of the Hesx1 show severe central nervous system defects, absence of optic vesicles, and a very small anterior pituitary gland. This phenotype is similar to the abnormalities observed in the(More)
Gitelman syndrome is a renal disorder characterized by hypokalemia, hypomagnesemia, metabolic alkalosis and hypocalciuria due to the defective tubular reabsorption of magnesium and potassium. This disease is caused by mutations of thiazide-sensitive Na-Cl cotransporter (TSC) gene. Gitelman syndrome is usually distinguished from Bartter syndrome by the(More)
A single giant geode at the olecranon in a patient with rheumatoid arthritis (RA) is relatively rare, and may cause diagnostic difficulties or cause a spontaneous pathological fracture owing to weakness of the cortical bone associated with osteoporosis. We report two cases of patients presenting with single giant geodes at the olecranon. In one case we(More)
Mutations of DSS (dosage sensitive sex reversal)-AHC critical region on the X chromosome, gene 1 DAX-1(NROB1)] results in X-linked adrenal hypoplasia congenita (AHC) and hypogonadotropic hypogonadism (HHG). Here we report four Japanese patients with AHC and HHG caused by the mutations of the DAX-1 gene. All patients manifested adrenal crisis at early(More)
Congenital lipoid adrenal hyperplasia (lipoid CAH) is the most severe form of CAH in which the synthesis of all gonadal and adrenal cortical steroids is markedly impaired. Lipoid CAH may be caused by the defect in either the steroidogenic acute regulatory (StAR) protein or the P450scc. More than 34 different mutations in StAR gene have been identified.(More)
Wrist arthrodesis is indicated for the rheumatoid hand especially in cases with severe destruction of the carpal bones. In the arthrodesis procedure for the rheumatoid wrist, autogenous iliac bone grafting is required in most cases. However, autogenous iliac bone graft necessitates the additional surgical intervention, and can be associated with the problem(More)
Recent advances in biologic therapy have enabled reduction of the progression of destructive arthritis in rheumatoid arthritis. Once destroyed, however, the affected bones and cartilage are not fully repaired. We describe the case of an 8-year-old girl with anti-citrullinated peptide antibody (ACPA)-positive polyarticular juvenile idiopathic arthritis(More)
Long-term results of open synovectomy of the elbow with rheumatoid arthritis (RA) were reviewed in 15 elbows. The subjects were evaluated at two time points with average follow-up periods of 4 and 8.7 years, and the results were compared between the two follow-ups. The Mayo Clinic performance score showed significant improvement in pain, motion, and daily(More)
Clinical squeal of the treatment of rheumatoid arthritis patients with methotrexate (MTX) according to the Japanese government recommended dose of 8 mg/week was evaluated prospectively. A total of 176 patients with active RA attending Konan Kakogawa Hospital and Kobe University Hospital were enrolled. Patients' profile at the start of study was Class 2.0(More)
CONTEXT Genomic rearrangements at 15q21 have been shown to cause overexpression of CYP19A1 and resultant aromatase excess syndrome (AEXS). However, mutation spectrum, clinical consequences, and underlying mechanisms of these rearrangements remain to be elucidated. OBJECTIVE The aim of the study was to clarify such unsolved matters.
