12/261. Florid osseous dysplasia of the mandible: report of a case.In 1986, a 60-year-old African American woman visited the Marquette University School of dentistry with a complaint of a vague, dull pain in her lower left quadrant. tooth No. 19 was extracted 10 years earlier because of extensive decay, and tooth No. 18 had received root canal therapy. A panoramic radiograph revealed the presence of ill-defined, multilocular, mixed (radiopaque-radiolucent) lesions present throughout the lower jaw. She was treated with antibiotics and scheduled for follow-up visits. When the symptoms persisted, tooth No. 18 was re-treated with root canal therapy and a representative biopsy was taken from the left mandibular area. The biopsy showed the presence of chronic osteomyelitis. The patient was treated with antibiotics and was scheduled for periodic check-up visits. In February 1995, she returned with the same symptoms in the left mandible. A panoramic radiograph showed persistence of the mixed radiopaque-radiolucent lesions throughout her mandible; however, the mass on the left side was more radiopaque and had assumed a "cotton wool" appearance. tooth No. 18 was extracted and a biopsy was taken from the area. After correlating the clinical behavior, radiographic appearance, and histopathologic features, a diagnosis of florid osseous dysplasia with osteitis was made. This case represents a classic example of the difficulty in diagnosing fibro-osseous lesions using radiographic interpretation alone and the need to correlate the clinical, radiographic, and histopathologic features to reach a diagnosis. Additionally, the present case clearly shows treatment problems of an otherwise self-limiting condition when secondary involvement with osteomyelitis is also present. A brief description of the conditions that were included in the differential diagnosis and their management is presented.- - - - - - - - - - ranking = 6.027390920936keywords = mandible, jaw, lower (Clic here for more details about this article) |
13/261. Resorption and regeneration of alveolar bone in acute osteomyelitis of the mandible.A 12-year-old boy developed osteomyelitis of the anterior part of the mandible subsequent to a blow on the mouth. The condition resulted in loosening of the lower incisors and considerable loss of alveolar bone. Under conservative treatment the condition subsided and the bone regenerated completely. Radiographs taken at various stages in the treatment show the loss of bone and its gradual regeneration.- - - - - - - - - - ranking = 5.0021162499813keywords = mandible, lower (Clic here for more details about this article) |
14/261. Report of a kindred with bone lesions and subcutaneous abscesses of unknown etiology.This case report concerns a 12-year-old boy who had a 9-year history of mandibular lesions of unknown origin. The mandible showed changes resembling chronic osteomyelitis. The tibia and temporal bone also exhibited radiolucencies. Many subcutaneous abscesses were present. The boy died at the age of 14 years as a result of rupture of the aorta. In his family, there were seven members who had bone lesions and eleven who suffered from skin abscesses.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
15/261. Diffuse chronic sclerosing osteomyelitis and the synovitis, acne, pustolosis, hyperostosis, osteitis (SAPHO) syndrome in two sisters.Two sisters with diffuse chronic sclerosing osteomyelitis of the mandible and the humerus and the synovitis, acne, pustolosis, hyperostosis and osteitis syndrome (SAPHO syndrome) are presented. The diagnoses of diffuse chronic sclerosing osteomyelitis at the age of 12 years and 27 years, respectively, were based on typical medical history, clinical symptoms and radiographic, histologic and scintigraphic findings. Because skin lesions and scintigraphic enhancement of the sternoclavicular joints with hyperostosis were present, a SAPHO syndrome was diagnosed in both sisters. Microbiological cultures of biopsy specimens revealed coagulase-negative staphylococcus aureus at the humerus and haemophilus parainfluenzae, streptococcus, actinomyces and Veilonella species at the mandible. Repeated operative procedures, including decortications, resection and reconstruction, and multiple histologic and microbiologic studies were performed over a period of up to 20 years. Since HLA typing yielded identical gene loci, we suggest that hereditary and autoimmune factors may play a role in the pathogenesis of these cases.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
16/261. Mandibular osteomyelitis caused by Blastoschizomyces capitatus in a child with acute myelogenous leukemia.A 6-year-old girl with acute myelogenous leukemia (AML) developed fungal mandibular osteomyelitis during chemotherapy. Blastoschizomyces capitatus was recognized histologically by its yeast-like morphology and formation of annelloconidia, and was confirmed by culture. The fungal osteomyelitis of the mandible was treated successfully with prolonged antifungal medication, extensive surgical debridement and an oral care program, without interrupting leukemia chemotherapy. B. capitatus osteomyelitis of the mandible may occur during chemotherapy in AML patients with poor dental condition. Successful treatment can be achieved by careful management without interruption of antineoplastic chemotherapy.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
17/261. osteomyelitis of the skull base with atypical onset and evolution.skull base osteomyelitis arises as a complication of malignant external otitis, but it can be also due to middle ear and/or mastoid infection. Other causes can be infections of the paranasal sinuses or of the mandible or maxilla due to odontic caries. Generally, osteomyelitis involves elderly patients affected by diabetic immunodeficiency or microvascular disease. In this paper, we present 3 new cases of skull base osteomyelitis with atypical onset and evolution. The difficulties of diagnosis and details of the management are discussed.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
18/261. Aggressive thoracic actinomycosis complicated by vertebral osteomyelitis and epidural abscess leading to spinal cord compression.STUDY DESIGN: Report of a successfully diagnosed and treated case of spinal cord compression due to epidural actinomycosis. OBJECTIVE: To illustrate that proper use of imaging strategy can greatly facilitate diagnosis and management of this rare condition. SUMMARY OF BACKGROUND DATA: Spinal actinomycosis causing epidural abscess and significant spinal cord compression is an uncommon condition. Although diagnosis is difficult, favorable results are widely reported when specific therapy is instituted. methods: A 32-year-old Chinese man had extensive dorsal thoracic soft tissue swelling and lower limb weakness. Collapse of the T5 vertebral body was found on plain radiographs with mediastinal infiltrates on chest radiograph. It took magnetic resonance imaging (MRI) to fully delineate the epidural abscess and dorsal muscular abscesses, which were not depicted by computed tomographic (CT) scan. diagnosis was made by examination of CT-guided aspirate and tissue recovered during surgery by a microbiologist. The patient received high-dose intravenous penicillin and prompt spinal decompression once diagnosis of actinomycosis was confirmed. RESULTS: The dorsal muscular abscesses and upper thoracic epidural abscess resolved rapidly after intravenous antibiotics and surgical drainage. This was well documented by follow-up MRI and the full recovery of motor power and lower limb sensation in the patient. CONCLUSIONS: High clinical suspicion and proper use of imaging data led to timely diagnosis of this rare case of mediastinal, epidural, and intramuscular thoracic actinomycosis. Specific antibiotic therapy and timely, well-targeted surgical intervention greatly improve the outcome of this condition.- - - - - - - - - - ranking = 0.0042324999625133keywords = lower (Clic here for more details about this article) |
19/261. osteomyelitis of the spine and abscess formation in the left thigh after stent-graft implantation in the superficial femoral artery.PURPOSE: To present a rare case of abscess formation around a covered stent in the superficial femoral artery. methods AND RESULTS: Two weeks after balloon dilation of a left superficial femoral artery (SFA) occlusion, during which a Hemobahn covered stent had been placed to treat dissection, a 77-year-old nondiabetic male developed intolerable pain and swelling of his left thigh. An abscess had formed around the stent, which was patent; intravenous antibiotic therapy quelled the symptoms, and the patient discontinued his oral antibiotic regimen weeks after discharge. General septicemia ensued. Acute lower limb ischemia and excruciating back pain prompted readmission. The SFA stent-graft occlusion required femoropopliteal bypass; the abscess and spondylodiskitis that had developed in the T12 and L1 vertebrae responded to intravenous antibiotics. The patient is without signs of infection at 6 months. CONCLUSIONS: Local and systemic infections associated with intraluminal prostheses are rare, and prophylactic antibiotic therapy is not commonly employed. Balloon- or device-induced arterial injury may expose the arterial wall to bacterial colonization, suggesting that patients receiving lengthy stents or experiencing arterial injury during angioplasty should receive antibiotics as a precautionary measure.- - - - - - - - - - ranking = 0.0021162499812566keywords = lower (Clic here for more details about this article) |
20/261. A fractured mandible, from initial operation to removal of tantalum mesh. Report of a case.Report is made of a case of fracture of the angle of the mandible. Treatment was attempted with the Sampson pericortical bone clamp, but was unsuccessful. Routine use of intraosseous wire led to a localized osteomyelitis, without union of the fracture. Treatment then was made with a particulate marrow graft contained within a tantalum mesh screen. The screen was removed 30 months postoperatively.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
