Drug-induced burning mouth syndrome: a new etiological diagnosis
2008
Burning mouth syndrome (BMS) is defined as a burning sensation of the oral mucosa, in the absence of specific oral lesions. The underlying etiology remains unclear. Peripheral alterations may be related to the density or reactive capacity of the oral mucosal membrane receptors - these being largely influenced by BMS-related risk factors such as stress, anxiety, the female gender, climacterium and advanced age. The present study compiles the cases of BMS induced by drugs reported in the literature, and attempts to draw a series of conclusions. A search was conducted in the PubMed® database using the following key words: burning mouth syndrome, drug-induced, antihypertensive and chemically-in…
Oral complaints in progressive systemic sclerosis : two cases report
2008
Progressive systemic sclerosis is a chronic sclerotic disease which causes diffuse, increased deposition of extracellular matrix in connective tissue with vascular abnormalities, resulting in tissue hypoxia. Aesthetic and facial dysfunction are followed by important oral and facial manifestation of disturbances such as xerostomia, the lack of saliva in the mouth, and its associated complications. Most clinical manifestations begin with tongue rigidity. The facial skin changes and bone resorption of mandible angle are often reported. Other systemic changes include the involvement of internal organs which leads to serious complications as well as disorders in the cardiac muscle and Raynaud´s …
Oncocytic metaplasia in inflammatory fibrous hyperplasia : histopathological and immunohistochemical analysis
2008
Oncocytic metaplasia (OM) is not a well-known feature in inflammatory fibrous hyperplasia (IFH) lesions, although it may be common, as proposed in our previous study about this lesion. In the present paper, we assessed the histopathological and immunohistochemical features of 18 cases of IFH containing OM areas. All the samples were examined on haematoxylin and eosin stained sections and cytokeratins (AE1/AE3, 34ßE12, CK5, CK7, CK8, CK13, CK14 and CK19), CD15, CD20, CD68, CD45Ro, and LCA primary antibodies were used. The vast majority of IFH occurred in women (n=14) and the most common site of presentation was the buccal vestibule. Oncocytic and salivary duct cells showed uniform immunoreac…
Oral implants in patients receiving bisphosphonates : a review and update
2008
This rewiew was mad to establish the convenience of dental implant treatment in patients receiving bisphosphonates or programmed to receive such drugs, with a description of their mechanisms of action and the way in which they can affect the mandibular or maxillary bone of dental implant candidates. In turn, a description is provided of the key elements for evaluating the benefit-risk ratio in patients treated with bisphosphonates who require oral surgery. Clinicians must be aware of the potential risk of osteonecrosis in patients treated with bisphosphonates via the oral or intravenous route. When bisphosphonates are administered via the intravenous route, all invasive oral procedures (inc…
Adenoid cystic carcinoma of the dorsum of the tongue : presentation of a case
2006
Adenoid cystic carcinoma is the most frequent malignant neoplasm of minor salivary glands (76.5%); it is clinically characterized by slow growth, and its most frequent localization is the hard palate. Histopathologically it presents three patterns, cribriform, tubular and solid; the solid type is related to a poor prognostic contrary to the cribriform type, which has a better prognosis. Surgical excision with wide margins is the treatment of choice, if it metastasizes to lymph nodules, post surgical radiotherapy is recommended. A 19 year-old man presented a recurrent lesion on the dorsum of the tongue previously diagnosed as monomorphic adenoma. In a second biopsy it was diagnosed as adenoi…
Prognostic significance of the anatomical location and TNM clinical classification in oral squamous cell carcinoma
2008
Objetives: The aim of this study was to investigate the existence of correlation between the TNM clinical classification, anatomical location and prognosis of oral squamous cell carcinoma. Study design: A total of 130 oral squamous cell carcinomas were selected from the files of the Dr. Luiz Antonio Hospital (Natal, Rio Grande do Norte, Brazil). Data concerning TNM clinical classification, anatomical location and prognosis were obtained. Pearsons correlation test was applied for the statistical analysis of data. Results: It revealed a statistically significant correlation (p = 0.01) between TNM clinical classification and prognosis. It also revealed correlation between TNM classification an…
Salivary concentration of TNF?, IL1?, IL6, and IL8 in oral squamous cell carcinoma
2008
Objectives: The aim of this study was to compare the concentration of tumor necrosis factor ?, interleukin 1?, 6, and 8 in the saliva of oral squamous cell carcinoma patients with control group. Study design: In this study 18 subjects were involved, nine patients with oral squamous cell carcinomas and nine age-sex-matched healthy individuals that were matched for gingival conditions too. Active dental abcesses, collagen vascular diseases, and infectious diseases during one month before saliva sampling were considered as exclusion criteria. Unstimulated whole saliva was collected and after processing the samples were analyzed by Enzyme Linked Immune Assay. Results: The concentration of saliv…
Dental management in renal failure : patients on dialysis
2008
Chronic renal failure is an important health care problem throughout the world, with an incidence of 337, 90, 107 and 95 new cases per million inhabitants/year in the United States, Australia, New Zealand and the United Kingdom, respectively. These figures moreover invariably tend to increase. During the progression of renal damage, clinical manifestations are noted in practically all body organs and systems, and 90% of all affected patients experience oral symptoms. The existing management options range from simple measures based on changes in diet and life style, to different forms of dialysis (hemodialysis and peritoneal dialysis), and also kidney transplantation. Given the multiple oral…
Classic Kaposi?s sarcoma presenting in the oral cavity of two HIV-negative Quechua patients
2007
Traditionally, classic KS lesions have a general distribution, often involving the skin of the feet and legs, and to a lesser extent, that of the hands, arms, and trunk. Oral involvement is a rare manifestation. Initial oral involvement is an even rarer occurrence. We report two unusual cases of classic KS presenting in the oral cavity of two patients from indigenous origin; the first patient with primary oral KS lesion on the hard palate, with no other signs of the condition in any other region of the body; the second patient with generalized dermal KS lesions with lymph node and lower lip involvement. In conclusion, clinicians and pathologists should be aware of the typical clinical, gros…
Gorlin-Goltz syndrome : Clinicopathologic aspects
2008
Gorlin-Goltz syndrome, also known as nevoid basal cell carcicoma syndrome, comes into being due to a genetic alteration produced by a mutation in the ?Patched? tumour suppressor gene, and it is inherited in a dominant autosomal way, though sporadic cases have been found. This syndrome shows a high penetrance and variable expressiveness. It is about a multisystemic process that is characterised by the presence of multiple pigmented basocellular carcinomas, keratocysts in the jaws, palmar and/or plantar pits and calcification of the falxcerebri. Together with these major features a great number of processes considered as minor features have also been described. The latter include numerous ske…
