BACKGROUND S-1 is an oral fluoropyrimidine whose antitumor effects have been demonstrated in treating various gastrointestinal cancers, including metastatic colon cancer, when administered as monotherapy or in combination chemotherapy. We conducted a randomized phase III study investigating the efficacy of S-1 as adjuvant chemotherapy for colon cancer by(More)
We report the case of a male patient with infantile hypophosphatasia associated with severe hypercalcaemia and mild respiratory insufficiency. At the age of 2 months, severe hypercalcaemia, low levels of serum alkaline phosphatase activity, and elevated urinary excretion of calcium and phosphoethanolamine were noted. Radiological findings showed generalized(More)
We report on two Japanese brothers with hereditary deficiency in γ-glutamyl transpeptidase. The propositus was 48 years old when he first visited our medical center and had a 51-year-old brother. The brothers were both tall and slender and had long limbs; the younger was diagnosed as having Marfan syndrome. Both patients both showed a tendency to retarded(More)
CONTEXT Natriuretic peptide receptor-B (NPR-B, GC-B in rodents; gene name NPR2) is a guanylyl cyclase-coupled receptor that mediates the effect of C-type natriuretic peptide. Homozygous mutations in human NPR-B cause acromesomelic dysplasia, type Maroteaux (OMIM 602875), an autosomal recessive skeletal dysplasia. NPR-B has an intracellular kinase homology(More)
The optic-spinal form of multiple sclerosis (OSMS), characterized by recurrent involvement of optic nerve and spinal cord with rare brain magnetic resonance imaging lesions, is relatively common among Asians. While individual cases of OSMS with anti-thyroid autoantibodies (ATABs) have been reported, the frequency of ATAbs in OSMS and classical multiple(More)
Although short-stature homeobox-containing gene (SHOX ) haploinsufficiency is responsible for Léri-Weill dyschondrosteosis (LWD), the molecular defect has not been identified in approximately 20% of Japanese LWD patients. Furthermore, although high prevalence of microdeletions affecting SHOX is primarily ascribed to the presence of repeat sequences such as(More)
We describe an infant with molybdenum cofactor deficiency, initially diagnosed as cerebral palsy. Clinical features of molybdenum cofactor deficiency, e.g., neonatal seizures, hypertonus/hypotonus, and feeding and respiratory difficulties, resemble those of neonatal hypoxic-ischemic encephalopathy. Our patient, a 2-year-old boy, presented with spastic(More)
The mechanism underlying the development of osteopenia or osteoporosis in longstanding phenylketonuria (PKU) remains to be clarified. We investigated the details of bone metabolism in 21 female and 13 male classical PKU patients aged 20–35 years. Vitamin D (VD), parathyroid hormone (PTH), bone turnover markers, and daily nutrient intake were examined. The(More)
Sirs, We have read with great interest the articles in this journal by Chiu [1] and Bircan [2] regarding poststreptococcal glomerulonephritis with pulmonary edema. Chiu et al. [1] described six school-age children with acute poststreptococcal glomerulonephritis (APSGN) and pulmonary edema which initially were misinterpreted as pneumonia. Similarly, Bircan(More)
