An increase of HLA-DR1 has been observed in schizophrenia patients from the Japanese population. A decrease of DR4, which was reported in Caucasian patients, has also been found in some of the Japanese studies. This small study further investigated frequencies of HLA-DR1 and DR4 in unrelated Japanese patients with schizophrenia (n = 45) and healthy(More)
OBJECTIVES To develop a clinically significant and practical enzyme-linked immunosorbent assay (ELISA) for the detection of MxA protein in human whole blood, a biological marker of viral infection. DESIGN AND METHODS A sandwich ELISA suitable for the measurement of human MxA protein in whole blood was developed using mouse monoclonal antibodies (mAbs)(More)
OBJECTIVE Five Japanese studies, to the authors' knowledge, without exception, have consistently shown an increased frequency of human leukocyte antigen (HLA)-DR1 in patients with schizophrenia. This suggests an association between HLA-DR1 and schizophrenia in the Japanese population. The mechanism of the association is unknown; however, prenatal infections(More)
Obesity may increase the risk of subsequent asthma. We have previously reported that there is a clear association between obesity and asthma in Japanese school-aged children. To evaluate whether a similar association exists in younger children, a nationwide cross-sectional questionnaire-based survey was performed focusing on children aged 4-5 yr. A child(More)
Standard exhalation time for measuring fractional exhaled nitric oxide (FeNO) is 10 sec, but this is not easy for younger children. We aimed to investigate the agreement between FeNO values during 10-sec (FeNO-10) and 6-sec (FeNO-6) exhalation and the feasibility of measuring FeNO-6, using a hand-held analyzer, NIOX-MINO®. FeNO values measured during 10-(More)
OBJECTIVE The Childhood Asthma Control Test (C-ACT), a seven-item, self-administered questionnaire, has been used as a tool to assess the control level in children with asthma. The aim of this study was to determine whether the C-ACT reflects airflow limitation and airway inflammation in addition to clinical manifestations. METHODS Asthmatic children aged(More)
BACKGROUND   Most studies regarding the association of obesity with asthma have been performed in the Western countries. This study is a nationwide survey conducted in Japan. METHODS   A cross-sectional and questionnaire-based survey was performed among children aged 6-7, 13-14, and 16-17 years, using the ISAAC questionnaire. Overweight was defined as BMI(More)
Febrile children are often given antibiotics empirically and unnecessarily. MxA is a protein induced in peripheral lymphoid cells by type 1 interferons during active viral infection. The ability of a whole blood ELISA assay for MxA to identify children with viral illness was studied in 122 children who presented with acute onset fever and 52 age-matched(More)
We present a case of mite-ingestion-associated exercise-induced anaphylaxis mimicking wheat-dependent exercise-induced anaphylaxis (WDEIA). A 17-year-old boy was referred for an episode of anaphylaxis while jogging, 1.5 h after having eaten okonomiyaki (a Japanese pancake). Laboratory measures revealed a slightly elevated specific immunoglobulin E (IgE)(More)
BACKGROUND A new electronic mesh nebulizer, eMotion is known to have higher performance compared to conventional nebulizers. However, there are some concerns about whether too much delivered dose might cause side effects with higher frequency. METHODS To evaluate the safety and usefulness of the nebulizer, we measured changes in heart rates and lung(More)
