Community-acquired pneumonia is the presence of signs and symptoms of lower respiratory tract infection acquired outside of the hospital.
The most common bacterial cause of childhood pneumonia is Streptococcus pneumoniae. It usually causes about 1/3 of radiographically-confirmed pneumonia in children <2 years of age.
Viruses commonly affect children <1 year of age than those aged >2 years, respiratory syncytial viruses (RSV) being the most frequently detected virus.
Mixed infection may occur in 8-40% of community-acquired pneumonia cases.
Intraoperative epidural analgesia, perioperative opioid and total dose of volatile agent appear to show some “clinically meaningful associations” with relapse-free survival (RFS) in children with solid organ tumour, particularly in paediatric sarcoma patients, according to a Singapore study. However, no statistically significant association exists between epidural use and an improved RFS.
