Altered cardiac rhythm in infants with bronchiolitis and respiratory syncytial virus infection.

Background: Although the most frequent extra-pulmonary manifestations of respiratory syncytial virus (RSV) infection involve the cardiovascular system, no data regarding heart function in infants with bronchiolitis associated with RSV infection have yet been systematically collected. The aim of this study was to verify the real frequency of heart involvement in patients with bronchiolitis associated with RSV infection, and whether infants with mild or moderate disease also risk heart malfunction.

Methods: A total of 69 otherwise healthy infants aged 1-12 months with bronchiolitis hospitalised in standard wards were enrolled.

Comparison of nasopharyngeal nylon flocked swabs with universal transport medium and rayon-bud swabs with a sponge reservoir of viral transport medium in the diagnosis of paediatric influenza.

This study compared a kit containing a nasopharyngeal nylon flocked swab and a tube with a liquid universal transport medium (UTM) with a kit containing a plastic-shafted rayon-budded swab with a sponge reservoir of viral transport medium for the molecular detection of influenza viruses in children. Respiratory samples were collected from 314 children aged <5 years with influenza-like illness (186 males; mean age 2.32+/-2.

Vaccines and preterm neonates: why, when, and with what.

This review analyses what is known concerning the immune response of preterm (PTIs) and low birth weight infants (LBWIs) to widely used vaccines, the protection they receive from routine immunisation, and the safety and tolerability of the vaccines themselves. It shows why PTIs and LBWIs should be vaccinated using the same schedules as those usually recommended for full-term infants (FTIs), except in the case of hepatitis B vaccine, whose schedule should be repeated in infants who received the first dose during the first days of life when they weighed less than 2000 g because of their reduced immune response. Vaccines are immunogenic, safe and well tolerated in PTIs and LBWIs, in whom early active immunisation is particularly important because they are among the most vulnerable subjects for pediatric infectious diseases.

Discontinuation of secondary prophylaxis for Pneumocystis pneumonia in human immunodeficiency virus-infected children treated with highly active antiretroviral therapy.

This study shows the long term safety of discontinuing secondary prophylaxis for Pneumocystis pneumonia in 5 human immunodeficiency virus-infected children who had recovered from a confirmed episode of Pneumocystis pneumonia, had <15% of CD4 cells at the time of starting highly active antiretroviral therapy and whose CD4 cell counts increased to >15% for >or=3 months during highly active antiretroviral therapy.

Evaluation of a rapid bedside test for the quantitative determination of C-reactive protein.

Regardless of its origin, any condition associated with inflammation is accompanied by an increase in serum C-reactive protein levels. This study compared the results of a rapid test for the bedside assay of C-reactive protein (QuikRead CRP, Orion Corporation, Orion Diagnostica, Espoo, Finland) with those of a standard laboratory assay in samples taken from 231 children aged less than 14 years (126 males; median age 4.7 years) attending the Emergency Department of Milan University's Institute of Pediatrics because of acute respiratory infection.
