Expression of Bcl-2 may play a dual role in tumor development and progression. Increased cell proliferation in the epithelium may present a predisposition to cancer in OLP. The expression of Ki-67 can be considered as an adjunct marker for proliferative activity in lesions with malignant potential. The prognostic value of these immunomarkers in the evaluation of precancerous oral lesions requires further investigation.
Our results demonstrated that M. alternifolia oil inhibited the growth of C. albicans. Moreover, both oils promoted significant adhesion reduction in the tested strains. These findings suggest the possibility of using these oils in prophylaxes against candidiasis.
Microscopic recognition of PLGA is facilitated by a characteristic combination of multiple architectural patterns of growth, infiltration of adjacent tissues and cytological aspects. These features are present even in small biopsy samples. The association of histopathological aspects with CK7, CK14, vimentin, S100 and α-SMA immunoexpression is helpful in reaching the diagnosis of doubtful cases.
Radiotherapy applies ionizing radiation at predetermined doses for a limited period of time in order to destroy tumors. The oral cavity, which has a high rate of cell renewal, is affected by the side effects of radiotherapy including osteoradionecrosis (ORN). This condition occurs due to irradiated bone tissue that becomes devitalized and exposed in the oral cavity. Conservative therapies are recommended for ORN lesions that are not extensive or in an early stage. Surgical intervention is necessary for extensive areas affected by necrosis. This study reports a case of ORN in the left mandibular body which resulted in a pathological fracture. The treatment consisted of segmental mandibulectomy and the use of a reconstruction plate. Also, low-level laser therapy around bone exposure was performed. After surgery, the patient underwent 6 months of follow-up and was satisfied with the outcome. However, the patient died before control of ORN was achieved due to a heart attack.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
