Chronic nonbacterial osteomyelitis is an autoinflammatory disease occurring mainly in children and adolescents, typically involving recurrent or persistent osteitic foci. The symptom is bone pain, possibly accompanied by soft tissue tenderness. Some patients exhibit symptoms of systemic inflammation. The. precise etiology of the disease is not known, but an imbalance of inflammatory and anti-inflammatory cytokines is presumed to play a role in the development of the disease. While an anti-inflammatory analgesic is in most cases sufficient to calm down the osteitis, the use of corticosteroids, anti- TNF-a inhibitors or bisphosphonates is required in some cases.

Background: The quality of workstation displays and viewing conditions affect the diagnostic information visible from digital radiographs., Materials and Methods: The image viewing practice at health centers in Northern Finland were surveyed with a questionnaire filled by 91 physicians. The quality of 23 monitors at ten health centers was measured., Results: Display performance and viewing conditions were poor. Sixty percent of radiographic exams remained without a statement from a radiologist. Only few physicians assessed the quality of displays., Conclusions: Health centers should invest into displays of diagnostic quality, consider the viewing conditions and perform systematic quality assurance of medical displays.
