1/9. Midfacial complications of prolonged cocaine snorting.Acute and chronic ingestion of cocaine predisposes the abuser to a wide range of local and systemic complications. This article describes the case of a 38-year-old man whose chronic cocaine snorting resulted in the erosion of the midfacial anatomy and recurrent sinus infections. Previously published case reports specific to this problem are presented, as are the oral, systemic and behavioural effects of cocaine abuse.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
2/9. Glandular odontogenic cyst. A rare entity with aggressive biological behaviour. A case report.Glandular Odontogenic cyst is an apparently rare jaw cyst characterised by typical histopathological features, propensity to reach large size and high rate of local recurrence, if not adequately treated. Identification of this cyst as a separate entity is important because of the difference in biological behaviour. We report a case of Glandular Odontogenic cyst occurring in maxilla.- - - - - - - - - - ranking = 5keywords = behaviour (Clic here for more details about this article) |
3/9. Unusual jaw lesions in the paediatric and adolescent patient: a management challenge.While major maxillofacial pathology in the young patient is relatively uncommon, non-malignant conditions may pose a significant treatment dilemma due to their aggressive or unpredictable behaviour. Several such diseases managed by the Oral and Maxillofacial Surgery Unit at the Royal Children's Hospital of Melbourne have been selected for review. Illustrative case reports to highlight the principles of management are presented.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
4/9. Radiological features of glandular odontogenic cyst.OBJECTIVES: To present five new cases of glandular odontogenic cyst (GOC) and to review the radiological features at presentation as reported in the English literature. methods: From 1993 to 2002, five patients in our department were diagnosed with GOC based on histopathological findings and supported by radiography and CT. The radiographic features of the new GOC cases were analysed in addition to 51 literature cases. RESULTS: There were 31 male and 25 female patients, aged 14-90 years (mean 50 years). The mandible was involved in 80% and the maxilla in 20%; most of the lesions were located in the anterior jaw. Radiographically, 52% of the lesions were unilocular and 48% were multilocular; 94.5% showed well defined borders, which were sclerotic in 7.7% and scalloped in 13%. Information on cortical plate integrity was available in only 24 cases: 50% showed perforation, 8.3% erosion of the cortical plates and 8.3% thinning of the cortical plates. root resorption was reported in 22% of patients and tooth displacement in 24.4%. CONCLUSIONS: Data collected indicate that GOC has potentially aggressive behaviour, with expansion and perforation in a significant number of cases. We recommend the use of multiple plane radiographs, with CT reserved for large lesions, especially those that are multilocular or involve extragnathic structures.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
5/9. Odontogenic keratocyst in maxillary sinus with invasive behaviour.Odontogenic keratocyst is a cystic lesion characterized by a high rate of recurrence. This report describes a rare case of ciliated epithelium-lined odontogenic keratocyst in the maxilla of a 27-year-old female. Panoramic radiography showed a lytic lesion on the right maxilla associated with an impacted molar tooth. Computerized tomography image revealed the involvement of the lesion with the right maxillary sinus, destroying the sinus floor. Histopathologically, the typical keratinized epithelial-lined cyst of odontogenic keratocyst abruptly changed into a ciliated epithelium, suggesting the fusion of both these epithelia rather a metaplastic transformation. The biological behaviour of odontogenic keratocysts is discussed.- - - - - - - - - - ranking = 5keywords = behaviour (Clic here for more details about this article) |
6/9. Limited regression of central giant cell granuloma by interferon alpha after failed calcitonin therapy: a report of 2 cases.Central giant cell granuloma (CGCG) is a benign lesion of the jaws with a sometimes locally aggressive behaviour. The most common therapy is surgical curettage which has a high recurrence rate, especially in lesions with aggressive signs and symptoms (i.e. pain, paresthesia, root-resorption and rapid growth). Alternative therapies such as interferon alpha (INFalpha) or calcitonin are described in the literature. In this study 2 patients with an aggressive CGCG are presented who were treated with INF mono-therapy. INF mono-therapy was capable of terminating the rapid growth of the lesion in both patients and induced a partial reduction. Total resolution, however, was not obtained and alternative treatment is still necessary.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
7/9. Odontogenic keratocyst of the maxilla: a case report.Remnants of odontogenic epithelium persist in oral tissues after odontogenesis is complete, and from these remnants a variety of tumours and cysts can arise. Squamous metaplasia can occur in this epithelium which in turn may produce keratin. Although keratin production is a feature of many odontogenic cysts, a specific entity, the odontogenic keratocyst has been defined. The term was first introduced by Philipsen in 1956 and has been used synonymously with that of the primordial cyst. Its capacity for aggressive growth and recurrence even after many years makes it of special interest. In this case report these behavioural characteristics are well demonstrated. The long natural history of the condition in this case and its site and size involved oral, ophthalmic and ultimately otolaryngologic surgeons.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
8/9. Orthokeratinized odontogenic cyst: a clinicopathological and immunocytochemical study of 15 cases.AIMS: Intraosseous jaw cysts with a solely orthokeratinized lining epithelium have been suggested to differ from the typical odontogenic keratocysts (OKC) by exhibiting a less aggressive behaviour. We report 15 cases of such cyst type under the term of 'orthokeratinized odontogenic cyst (OOC)' and compared their clinical, histological and immunocytochemical features with that of OKC. methods AND RESULTS: The cysts of the present series were all solitary lesions, occurred mostly in young male patients, and showed a predilection for the posterior mandible areas. Follow-up of 14 patients, nine of whom were treated by simple enucleation, revealed no recurrence over a period of 3.5-12 years after surgery. None of the patients had any association with the naevoid basal cell carcinoma syndrome. Furthermore, histological and immunocytochemical comparison between OOC and OKC revealed marked differences in their morphology and epithelial expression. The lining epithelium of OOC lacked the typical features of OKC and appeared to show a lower proliferative activity. CONCLUSION: These findings suggest that OOC is clinicopathologically separate from other types of odontogenic cysts and may thus constitute a distinct clinical entity.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
9/9. Fibrous dysplasia of the jaw bone: a review of 15 new cases and two cases of recurrence in jamaica together with a case report.The authors reviewed 15 new cases of fibrous dysplasia of the jaw bone and two cases of recurrence seen in jamaica between 1980 and 1995. Only cases which had a histological confirmation of fibrous dysplasia were included. The clinical behaviour and radiological findings of these cases were studied from the case files, either at the Cornwall Regional Hospital or the Kingston Public Hospital in jamaica.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
