BACKGROUND Pressure ulcers represent a particularly difficult disease process and remain a financially important entity. The underlying bone in advanced ulcers may harbor osteomyelitis. Radiologic diagnosis of osteomyelitis is confounded by chronic pressure and shear. We sought to determine the test characteristics of preoperative magnetic resonance imaging (MRI) in the diagnosis of osteomyelit...

BACKGROUND The most common cause of perihilar obstruction is cholangiocarcinoma, especially in Thailand. Benign perihilar stricture represents less than 20% of cases. IgG4-related disease and IgG4-related sclerosing cholangitis, however, have been receiving increased recognition. Isolated IgG4-related sclerosing cholangitis is less common. The preoperative diagnosis of IgG4-related sclerosing c...

This report describes a rare case of chronic osteomyelitis in a 60 year old man mimicking a soft tissue sarcoma. Chronic osteomyelitis is an infrequent cause of a soft tissue mass and is usually diagnosed clinically by a combination of radiology and microbiology. Rarely, COM can mimic a primary bony neoplasm, but this is the first reported case where it mimicked a soft tissue sarcoma. The clini...

Tuberculosis osteomyelitis of foot bones is uncommon and may evade the diagnosis for long time because of atypical presentation, paucibacillary nature and relatively normal picture on laboratory investigations. As tuberculosis of bone mimic like chronic osteomyelitis, clinical picture with confection by other organism lead to misdiagnosis. A case of tubercular osteomyelitis of talus reported he...

Osteomyelitis is a bone infection caused by bacteria or other germs. Gram-positive cocci are the most common etiological organisms of calcaneal osteomyelitis; whereas, non-tuberculous mycobacteria (NTM) are rarely documented. We reported a case of NTM calcaneal osteomyelitis in a 51-year-old female patient. She had been previously treated in many local clinics with multiple local steroid inject...

We describe 22 patients who presented between the ages of 4 and 14 years with gradual onset of malaise and pain at the sites of multiple bone lesions. The symptoms from the bone lesions were sometimes sequential in onset and often relapsing. The radiological findings were typical of osteomyelitis. Radioisotope bone scans identified some clinically silent lesions. Bone biopsies were performed in...

Chronic osteomyelitis of maxilla and mandible is rare in industrialized countries and its occurrence in developing countries is associated with trauma and surgery, and its microbial etiology has not been studied thoroughly. The aim of this investigation was to evaluate the microbiota associated with osteomyelitis of mandible or maxilla from some Brazilian patients. After clinical and radiograph...

In the bone microenvironment, tumour necrosis factor (TNF) has long been established as a stimulator of osteoclasts, hence leading to bone resorption, yet it also induces osteoblasts, the bone-forming cells, to proliferate, which may have longer term influences on bone formation. A disturbance in the finely balanced processes of bone resorption and formation, termed remodelling, results in a di...

INTRODUCTION Idiopathic sclerosing orbital inflammation is a rare and ill-defined heterogeneous entity, and a distinct subset of orbital inflammation. Recently, attention has been focused on immunoglobulin G4-related disease complicated with fibrotic changes in some other organs with high serum immunoglobulin G4 levels. This report presents a case of suspected idiopathic sclerosing orbital infl...
