Clinical effectiveness of four neuraminidase inhibitors (oseltamivir, zanamivir, laninamivir, and peramivir) for children with influenza A and B in the 2014-2015 to 2016-2017 influenza seasons in Japan.

The clinical effectiveness of four neuraminidase inhibitors (NAIs) (oseltamivir, zanamivir, laninamivir, and peramivir) for children aged 0 months to 18 years with influenza A and B were investigated in the 2014-2015 to 2016-2017 influenza seasons in Japan. A total of 1207 patients (747 with influenza A and 460 with influenza B) were enrolled. The Cox proportional-hazards model using all of the patients showed that the duration of fever after administration of the first dose of the NAI was shorter in older patients (hazard ratio = 1.

Therapeutic efficacy of azithromycin, clarithromycin, minocycline and tosufloxacin against macrolide-resistant and macrolide-sensitive Mycoplasma pneumoniae pneumonia in pediatric patients.

Objective: To clarify therapeutic effects of azithromycin, clarithromycin, minocycline and tosufloxacin against macrolide-resistant Mycoplasma pneumoniae (MRMP) pneumonia and against macrolide-sensitive Mycoplasma pneumoniae (MSMP) pneumonia in pediatric patients.

Methods: A prospective, multicenter observational study was conducted from July 2013 to August 2015. The therapeutic effects of azithromycin, clarithromycin, minocycline and tosufloxacin were evaluated in 59 patients with pneumonia caused by MRMP and in 50 patients with pneumonia caused by MSMP.

Regional Differences in Prevalence of Macrolide Resistance among Pediatric Mycoplasma pneumoniae Infections in Hokkaido, Japan.

Recently, macrolide-resistant (MR) Mycoplasma pneumonia appeared, and prevalence of macrolide resistance among M. pneumoniae infections varies by country. However, reports on regional differences in the prevalence of MR M.

Sensitivity and Specificity of a Loop-Mediated Isothermal Amplification Assay for the Detection of Mycoplasma Pneumonia from Nasopharyngeal Swab Samples Compared with those of Real-time PCR.

Background: The aim of this study was to determine the sensitivity and specificity of a loop-mediated isothermal amplification (LAMP) assay kit for the detection of Mycoplasma pneumonia (Eiken Chemical Co., Ltd, Tokyo, Japan) from nasopharyngeal swab samples compared with those of real-time PCR.

Methods: Nasopharyngeal swab samples taken from 223 patients aged 3 - 18 years who were suspected of having respiratory tract infections associated with Mycoplasma pneumonia were used in this study.

Comparison of the clinical effectiveness of zanamivir and laninamivir octanoate for children with influenza A(H3N2) and B in the 2011-2012 season.

Objectives: To evaluate the clinical effectiveness of the two inhaled neuraminidase inhibitors (NAIs), zanamivir (ZN) and laninamivir octate (LO), for influenza A(H3N2) and B virus infections.

Design: A prospective, multicenter observational study was conducted from January to April in 2012.

Setting: Outpatients aged 5-18 years who had a temperature of 37.

Detection of human bocaviruses 1 to 4 from nasopharyngeal swab samples collected from patients with respiratory tract infections.

Human bocaviruses (HBoV) 1, 2, 3, and 4 (HBoV1-4) were detected in 132 (15.5%), 5 (0.6%), 3 (0.

Prolonged anemia by superinfection of parvovirus B19 in a boy with enterohemorrhagic Escherichia coli O157-associated hemolytic uremic syndrome.

We report a 3-year-old boy with enterohemorrhagic Escherichia coli (EHEC) O157-associated hemolytic uremic syndrome (HUS). His anemia was associated with decreased reticulocyte count and persisted after the recovery from HUS. Superinfection of parvovirus B19 (PVB19) was proven by a transient febrile episode associated with IgM antibodies to the virus and the delayed appearance of IgG antibodies and typical rashes.
