BACKGROUND Myocarditis (MC) is an important cause of cardiac dysfunction in children. Fulminant MC is sometimes fatal, and sequelae may develop during follow-up. We conducted a nationwide survey to determine the clinico-epidemiological features of MC in Japanese children and adolescents. METHODS AND RESULTS Survey questionnaires were mailed to 627(More)
Congenital heart defects (CHD) are very common in patients with trisomy 18 (T18) and trisomy 13 (T13). The surgical indication of CHD remains controversial since the natural history of these trisomies is documented to be poor. To investigate the outcome of CHD in patients with T18 and T13, we collected and evaluated clinical data from 134 patients with T18(More)
Our purpose is to study the effect on the blood flow caused by the valve in blood vessel. We examine the possibility that thrombosis is caused by pressing the artificial valve. We tried to solve the flow of blood by numerical analysis with an incompressibility Navier-Stokes equation. We supposed the static boundary condition about vessel shape, although(More)
BACKGROUND Aseptic meningitis is a serious adverse reaction to intravenous immunoglobulin (IVIG) therapy. We studied the clinical characteristics of patients with acute Kawasaki disease (KD) who developed IVIG-induced aseptic meningitis. METHODS A retrospective analysis of the medical records of patients with KD who developed aseptic meningitis after IVIG(More)
BACKGROUND There is little data on the long-term effects of continuous intravenous epoprostenol for children with idiopathic pulmonary arterial hypertension (IPAH) in Japan. METHODS AND RESULTS Thirty-one IPAH patients younger than 18 years old who had begun epoprostenol therapy at Toho University Omori Medical Center between January 1999 and June 2004(More)
BACKGROUND Previous studies have reported a high prevalence of autoimmune thyroid disease (AITD) in adult patients with pulmonary arterial hypertension (PAH). The aim of this retrospective study was to determine the prevalence of AITD in children and adolescents with idiopathic PAH (IPAH). METHODS AND RESULTS The study group included 16 patients who had(More)

It is well known that the pathogenesis of essential hypertension is multi-factorial, and that the environmental and genetic factors and their interaction play important roles on pathogenesis of hypertension. The environmental factors consist of natural environmental factors, such as weather, seasons, temperature, soil and water, and social environmental(More)
Future Japanese population pyramid and death toll are similarity. According to the national census performed in last October, Japan entered population decline society. A trend of population of man and woman is shown until 2060. A calculation results are shown every five years. The population is classified in an age-grade every 5 years old. The population of(More)
Female adnexal tumors of probable wolffian origin (FATWO) are rare neoplasms believed to originate from mesonephric (wolffian) remnants. Rarity and variable location of FATWO make the diagnosis difficult. Although most cases follow a benign clinical course, approximately 10% of them either recur or metastasize and are thought to be resistant to(More)
This study analyzed the direct and indirect CO 2 emissions of the energy-intensive basic metals industry, in particular steels, using the distributions of various energy sources, including coal/peat, oil, and electricity, from an input–output table. An analysis of five major steel producing countries indicated that direct CO 2 emissions increased 1.4-fold(More)
