Multicenter Study
Inter-observer variation in the interpretation of chest radiographs for pneumonia in community-acquired lower respiratory tract infections.
To assess inter-observer variation in the interpretation of chest radiographs of individuals with pneumonia versus those without pneumonia. ⋯ The overall inter-observer agreement adjusted for chance was moderate. Inter-observer agreement in cases with pneumonia was much worse than the agreement in negative (i.e. non-pneumonia) cases. A general practitioner's selection of patients with a higher chance of having pneumonia for chest radiography would thus not improve the observer agreement.

To evaluate the factors associated with delayed diagnosis of foreign body aspiration (FBA) in children and to compare clinical, radiological and bronchoscopic findings in the patients with suspected FBA. ⋯ To prevent delayed diagnosis, characteristic symptoms, signs and radiological findings of FBA should be checked in all suspected cases. As clinical and radiological findings of FBA in delayed cases may mimic other disorders, the clinician must be aware of the likelihood of FBA. Regardless of radiological findings, bronchoscopy should be considered in patients with an appropriate history.

To investigate the short-term outcome and associated injuries of bone bruising in the acutely injured knee. ⋯ Bone bruises persist for at least 12-14 weeks, which is longer than previously quoted. Two discrete patterns of bone bruise resolution have been demonstrated. The size and persistence of bone bruising is not related to the presence or absence or type of associated ligamentous injuries.

To establish the relationship between the tip position of tunnelled central venous catheters (CVC) and the incidence of venous thrombosis. ⋯ Distal placement of tunnelled CVC, either in the distal third of the SVC or proximal RA is optimal.
