Human papillomavirus: Its identikit and controversial role in oral oncogenesis, premalignant and malignant lesions (Review)
2007
Human papillomaviruses (HPVs) are a group of host-specific DNA viruses, with a remarkable epithelial cell specificity: they have been reported principally in the ano-genital tract, urethra, skin, larynx, tracheo-bronchial and oral mucosa. More than 100 different HPV types have been identified and classified as high (e.g. 16, 18, 31) or low (e.g. 11, 42, 36) -risk (HR and LR), based on their association with cervical carcinoma. The carcinogenic role of HR-HPV revolves mainly around two of its oncoproteins: HPV-E6 which promotes degradation of the p53 tumour suppressor gene product and HPV-E7 which modifies the pRb tumour suppressor gene product, inhibiting the activity of TGF-beta2. Since th…
Bcl-2 as prognostic factor in head and neck squamous cell carcinoma
2005
A series of 66 cases of oral squamous cell carcinoma (OSCC) was retrospectively analyzed by immunohisto-chemistry for bcl-2 expression to verify its predictive value for clinical outcome in patients with OSCC. After grouping for bcl-2 expression, OSCCs were statistically analyzed for the variables age, gender, histological grading (G), TNM, staging, recurrence, and overall survival rate. Univariate and multivariate (Cox regression) analyses were performed. Thirty-six OSCC (54.5%) showed expression for bcl-2, whereas 30 (44.5%) were negative. No statistical association was found between bcl-2 expression and any variables considered at baseline. Overall disease-specific survival rate at 72 mo…
HPV in oral squamous cell carcinoma vs head and neck squamous cell carcinoma biopsies: a meta-analysis (1988-2007).
2008
Abstract INTRODUCTION: In the literature, there exists a wide range of human papillomavirus (HPV) DNA prevalence for head and neck squamous cell carcinoma (HNSCC), especially in relation to methods of viral detection and the lesion site. We estimated the pooled prevalence of HPV DNA in biopsies of HNSCC generically grouped versus oral squamous cell carcinoma (OSCC) in relation to the method of viral DNA detection, with the primary end point of verifying if these two variables (specification of tumour site and method of HPV DNA identification) influence the datum on HPV assay. METHODS: By means of MEDLINE/PubMED/Ovid databases, we selected studies examining paraffin-embedded (PE) biopsies of…

Malattia parodontale e malattia cardiovascolare: correlazione o semplice coincidenza? Revisione della letteratura

The present paper reviews relationship between chronic periodontitis and cardiovascular diseases. Original papers on this subject, published in English in the period between 2001 and the first semester 2006, were located in the MEDLINE/PubMed database. Additional studies were obtained by searching reference lists of previously published papers. Periodontal infection provides a chronic reservoir of inflammatory mediators and cytokines, lipopolysaccharide, which contribute to the formation of atheroma. Moreover, periodontal pathogens can penetrate the epithelial barrier of the periodontal tissues and reach the blood stream, carrying out a local atherogenic activity. Some studies indicated tha…
