Osteomyelitis
Updated: Wikipedia source
Osteomyelitis (OM) is the infectious inflammation of bone marrow. Symptoms may include pain in a specific bone with overlying redness, fever, and weakness. The feet, spine, and hips are the most commonly involved bones in adults. The cause is usually a bacterial infection, but rarely can be a fungal infection. It may occur by spread from the blood or from surrounding tissue. Risks for developing osteomyelitis include diabetes, intravenous drug use, prior removal of the spleen, and trauma to the area. Diagnosis is typically suspected based on symptoms and basic laboratory tests as C-reactive protein and erythrocyte sedimentation rate. This is because plain radiographs are unremarkable in the first few days following acute infection. Diagnosis is further confirmed by blood tests, medical imaging, or bone biopsy. Treatment of bacterial osteomyelitis often involves both antimicrobials and surgery. Treatment outcomes of bacterial osteomyelitis are generally good when the condition has only been present a short time. In people with poor blood flow, amputation may be required. Treatment of the relatively rare fungal osteomyelitis as mycetoma infection entails the use of antifungal medications. In contrast to bacterial osteomyelitis, amputation or large bony resections is more common in neglected fungal osteomyelitis (mycetoma) where infections of the foot account for the majority of cases. About 2.4 per 100,000 people are affected by osteomyelitis each year. The young and old are more commonly affected. Males are more commonly affected than females. The condition was described at least as early as the 300s BC by Hippocrates. Prior to the availability of antibiotics, the risk of death was significant.
