Alternative sampling methods for detecting bacterial pathogens in children with upper respiratory tract infections.

Nasopharyngeal sampling is used for detecting bacteria commonly involved in upper respiratory tract infections, but it requires training and may not always be well tolerated. We sampled children (n = 66) of ages 0 to 4 years, with rhinorrhea, by using a nasopharyngeal swab, a nasal swab, and nose blowing/wiping into a paper tissue. Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Staphylococcus aureus were cultured at similar rates across methods with high concordance (80 to 97%), indicating that they are reliably detected by alternative means.

The sleep position trainer: a new treatment for positional obstructive sleep apnoea.

Background: Positional obstructive sleep apnoea (POSA), defined as a supine apnoea-hypopnoea index (AHI) twice or more as compared to the AHI in the other positions, occurs in 56 % of obstructive sleep apnoea patients. Positional therapy (PT) is one of several available treatment options for these patients. So far, PT has been hampered by compliance problems, mainly because of the usage of bulky masses placed in the back.
