1/17. Massive osteolysis of the mandible: report of a case with multifocal bone loss.osteolysis of the jaws has been reported in association with infection, cysts, neoplasia, and metabolic, endocrine, or hematologic abnormalities. Rare cases of idiopathic osteolysis have also been recorded. We report the case of a 10-year-old girl with mandibular basal and alveolar bone resorption that has continued over a period of 9 years. The patient has subsequently developed bilateral resorption of the ascending rami and condyles. The maxilla is uninvolved. Investigations included radiology, computerized tomography, scintigraphy, hematology, serum chemistry, endocrinology, histopathology, microbiology, and immunology. Neutrophil chemotaxis, chemiluminescence, and random migration values were low but within the normal range. These findings are interpreted as indicating an unusual variant of massive osteolysis.- - - - - - - - - - ranking = 1keywords = endocrine (Clic here for more details about this article) |
2/17. Decisive diagnosis of infected mandibular osteoradionecrosis with a Tc-99m-labelled anti-granulocyte Fab'-fragment.The accepted golden standard for detection of inflammatory bone disease is conventional three-phase bone scanning. Hyperperfusion, a high blood-pool activity and elevated bone metabolism are typical signs for an acute osteomyelitis. However, in case of subacute, chronic inflammation, neither elevated blood flow nor high blood-pool activity may be seen. This may cause difficulties in differentiating such cases from neoplastic or postoperative changes. This case report verifies the possible advantage of immunoscintigraphy with Tc-99m-labelled anti-granulocyte Fab'-fragments (LeukoScan) in a patient with infected mandibular osteoradionecrosis, who had equivocal clinical symptoms and questionable radiographic results. LeukoScan is shown to be more sensitive in case of subacute bone inflammation compared with three-phase bone scanning. However, acquisition of delayed images after 24 hours including SPECT is inevitable in case of negative scans during the first hours of investigation.- - - - - - - - - - ranking = 377.85033707401keywords = bone disease (Clic here for more details about this article) |

4/17. Otolaryngological complications of osteopetrosis.osteopetrosis is a rare inherited bone disease that affects both humans and various mammals. The authors report on two cases of osteopetrosis with otolaryngological complications. One patient had the childhood form and presented with chronic otitis media and brain abscess. The second patient had the adult form and presented with sinusitis from tooth extraction which developed into chronic osteomyelitis of the maxillary bone.- - - - - - - - - - ranking = 377.85033707401keywords = bone disease (Clic here for more details about this article) |
5/17. Brown tumor in children with normocalcemic hyperparathyroidism: a report of two cases.Brown tumor is an important sign of a number of metabolic bone diseases. Normocalcemic hyperparathyroidism, a rare childhood pathologic finding, reveals itself with brown tumors as the only initial sign. In this study, two cases of normocalcemic hyperparathyroidism accompanied by mandibular brown tumors are presented.- - - - - - - - - - ranking = 377.85033707401keywords = bone disease (Clic here for more details about this article) |
6/17. cherubism in siblings: a case report.cherubism is a non-neoplastic bone disease characterized by clinically evident bilateral, painless enlargements of the jaws that are said to give the patient a cherubic appearance. cherubism may appear in solitary cases or in many members of the same family, often in multiple generations. On radiography, the lesions exhibit bilateral multilocular radiolucent areas. Histopathologic evaluation reveals proliferating fibrous connective tissue containing numerous multinucleated giant cells. Since the first description of this condition in 1933, almost 200 cases have been reported. We describe cherubism in 2 siblings and briefly review the literature on this subject.- - - - - - - - - - ranking = 377.85033707401keywords = bone disease (Clic here for more details about this article) |
7/17. Vanishing bone disease in a five year old: report of a case and review of the literature.Vanishing bone disease is a rare condition of unknown aetiology. It can affect almost any bone, including those of the maxillofacial region. It is most commonly seen in the second and third decades of life. To the author's knowledge, this is the second case reported in the maxillofacial region of a child within the first decade of life, and the first who survived.- - - - - - - - - - ranking = 1889.2516853701keywords = bone disease (Clic here for more details about this article) |
8/17. Total mandibular reconstruction for massive osteolysis of the mandible (Gorham-Stout syndrome).Massive osteolysis (Gorham-Stout syndrome) is a rare condition of unknown aetiology that is thought to result from a localised endothelial proliferation of lymphatic vessels resulting in destruction and absorption of bone. The diagnosis of Gorham-Stout syndrome can be made only after first excluding osteolysis from infection, inflammation, endocrine disease, and cancer. The syndrome is rarely seen in the facial skeleton and has a variable prognosis. Many treatments have been advocated but only surgery and radiotherapy have had some success. We present a case of massive osteolysis of the entire mandible, which was reconstructed with a free vascularised fibular graft and bilateral prosthetic replacements of the temporomandibular (TMJ) joints. Four years later the fibular graft had been absorbed requiring further reconstruction with another fibula graft.- - - - - - - - - - ranking = 1keywords = endocrine (Clic here for more details about this article) |
9/17. Gorham's disease of the mandible mimicking periodontal disease on radiograph.BACKGROUND: Gorham's disease is a rare disorder characterized by spontaneous and progressive osteolysis of one or more skeletal bones. The radiographic findings associated with Gorham's disease are particularly dramatic, as in some cases a complete resorption of the involved bone can occur, leading to the definition of phantom bone, vanishing bone, or disappearing bone disease. MATERIAL AND methods: A 24-year-old female patient with a previous diagnosis of periodontal disease and progressive mandibular alveolar bone loss was referred to our oral medicine section. The initial radiographic picture showed infrabony defects and horizontal bone loss. RESULTS: After further extensive local and systemic evaluation, including histopathological, laboratory and imagine techniques investigations, the patient was diagnosed to be affected by Gorham's disease. Meanwhile the progression of the osteolytic process had caused the loosening of all the left mandibular teeth and a pathologic fracture. Appropriate medical therapy was successful in stabilizating the resorptive process, with no evidence of further progressive disease. CONCLUSIONS: When Gorham's disease involves the mandible, the role of the periodontologist is extremely important in diagnosing promptly the disorder and preventing the functional and aesthetic consequences of advanced and extensive bone loss. Gorham's disease should be included among the pathologic entities mimicking periodontal disease on radiograph, such as inflammatory disease (e.g. osteomyelitis), endocrine disease (e.g. hyperparathyroidism), intra-osseous malignancies or metastases, lymphoma, histiocytosis X, mainly eosinophilic granuloma, infective process (e.g. tuberculosis and actinomycosis), odontogenic tumours.- - - - - - - - - - ranking = 378.85033707401keywords = bone disease, endocrine (Clic here for more details about this article) |
10/17. jaw bone necrosis without previous dental extractions associated with the use of bisphosphonates (pamidronate and zoledronate): a four-case report.jaw bone necrosis is a clinical condition associated with defects in vascularization of the maxilla or the mandibular bone, usually present following head and neck radiotherapy and/or oral surgical interventions. Bisphosphonates are synthetic analogues of pyrophosphate used in the treatment of patients with hypercalcemia as a result of malignancy, bone metastasis and for the treatment of other disorders such as metabolic bone diseases, Paget's disease and osteoporosis. Over last 10 years, cases of jaw bone necrosis have been associated with the use of bisphosphonate therapy. In particular, Ruggiero et al. (J Oral Maxillofac Surg 2004; 62: 527-534) in 2004 described a large group of patients (63) with jaw bone necrosis probably related to the use of these drugs. It should be noted that all the patients in the group described either underwent head and neck radiotherapy or had a dental extraction while taking bisphosphonates. In the present study, we reported four cases of jawbone necrosis in patients taking pamidronate (Aredia) and zoledronate (Zometa) without having undergone any kind of radiotherapy or dental surgery. All the patients were females between the ages of 56 and 71 years; three were treated with bisphosphonates for bone metastasis and one for multiple myeloma. All the patients received surgical treatment with bone curettage, with partial and/or temporary improvement of the lesions. Although a treatment for bisphosphonate-induced bone lesions has not yet been established, we suggest careful evaluation of the patients' oral health before prescribing bisphosphonate treatment.- - - - - - - - - - ranking = 377.85033707401keywords = bone disease (Clic here for more details about this article) |
