BACKGROUND The aim of the study was to estimate the left ventricular contractility using the ratio of left ventricular end-systolic wall stress to left ventricular end-systolic volume index in patients with iron deficiency anemia, for which there are no previous reports. METHODS Cardiovascular functions were evaluated using echocardiography and pulsed(More)

ISSN 0001-5555 Sir, Acquired reactive perforating collagenosis (ARPC) is associated with diabetes mellitus and/or chronic renal failure. The disease lesions consist of many dome-shaped nodules, which have a central umbilication containing firm keratotic(More)
BACKGROUND Vitamin D is an immunomodulatory molecule related to innate immunity that may contribute to the increased occurrence of acute lower respiratory infection (ALRI) in children, one of the most common reasons for hospitalization and intensive care unit admission. In the present study, the association between vitamin D deficiency and the severity of(More)
We investigated myocardial ischemia and old myocardial infarction noninvasively using signal-averaged electrocardiographic late potentials (LPs) in patients with Kawasaki disease. Patients were divided into 4 groups: a noncoronary artery lesion group (n=136), a coronary artery lesion group (without myocardial ischemia and an old myocardial infarction;(More)
BACKGROUND Dalteparin, a low-molecular-weight heparin, has anticoagulant and anti-angiogenic activity. This study investigated whether dalteparin reduced coronary artery lesion (CAL) prevalence, and resistance to intravenous immunoglobulin (IVIG) therapy in Kawasaki disease (KD). METHODS This retrospective study comprised two parts. In the first cohort,(More)
Although the DEAD-box RNA helicase family is ubiquitous in eukaryotes, its developmental role remains unelucidated. Here, we report that cooperative action between the Arabidopsis nucleolar protein RH10, an ortholog of human DEAD-box RNA helicase DDX47, and the epigenetic repressor complex of ASYMMETRIC-LEAVES1 (AS1) and AS2 (AS1-AS2) is critical to repress(More)
Fundamental and clinical evaluations were made on cefoxitin, a new cephamycin antibiotic, and the following results were obtained. 1) MIC of the drug to clinical isolates was determined and was higher than that of cefazolin to Gram-positive bacilli. Among Gram-negative rods, the drug showed a sufficient antibacterial activity even to cefazolin-resistant(More)
We report a 74-year-old woman who presented to hospital with fever, vomiting, diarrhea, and 2 weeks later developed erythema nodosum (EN) on the legs, and was diagnosed with Yersinia enterocolitica infection based on her clinical course and microbiological examination of the stool. She also had a complication of pancreatitis, which made the diagnosis(More)
A simple modified Roux-en-Y anastomosis--esophagojejunoduodenostomy with circuit duodenal loop (circuit Roux-en-Y anastomosis) after total gastrectomy--has been performed in ten consecutive patients without any operative death or complications. The simplicity and safety of this procedure may well be more worthwhile than other forms of alimentary tract(More)
A 5-week-old male infant who was referred to our hospital because of tachypnea and poor feeding. An electrocardiogram showed a deep Q wave in lead aVL, negative T waves in leads I, II, III, aVF and V6 and a positive T wave in VL. Echocardiography revealed severely impaired left ventricular function. Aortography confirmed with a diagnosis of anomalous origin(More)
