Is serum procalcitonin a reliable diagnostic marker in children with acute respiratory tract infections?
Taken the results of this retrospective analysis, serum PCT values below 0.1 ng/ml might be a marker to identify children with acute respiratory tract infection in whom antibiotic treatment could be withheld. However, only a prospective intervention trial will prove the general safety of this limit.
The findings from this study add to the body of literature which suggests the importance of socioeconomic factors as an influence on health, including resultant disability related to chronic musculoskeletal conditions such as back pain. Work status was particularly dominant in our findings and may suggest that helping patients with back pain back to work where appropriate, is an especially important part of the management process.
