Epstein-Barr virus in oral proliferative verrucous leukoplakia and squamous cell carcinoma : a preliminary study
The aim of this study was to analyze proliferative verrucous leukoplakia (PVL) and oral squamous cell carcinoma (OSCC) for the possible presence of Epstein-Barr virus (EBV). We studied three groups: Sub-Group 1 was composed of 10 patients with PVL, (6 of whom had developed OSCC); Sub-Group 2 comprised 5 patients with OSCC but no preceding PVL; and Sub-Group 3 were 5 controls with clinically normal oral mucosa. Oral biopsies from all cases were examined for Epstein-Barr virus (EBV) by nested PCR. EBV was detected in 60% of Sub-Group 1 patients (PVL ) and in 40% of Sub-Group 2 (OSCC), but in 0% of SubGroup 3 (controls).
Benign tumors of the oral mucosa: A study of 300 patients
Objectives: To analyze the frequency and type of the most common benign tumors of the oral mucosa found at the Hospital Stomatology Service, and to study the clinical characteristics and possible etiological factors. Material and Methods: This is a retrospective study of 300 patients with histologically diagnosed benign tumors of the oral mucosa. Data was compiled for each case, documenting information relating to age, gender, medication, habits (smoking, oral hygiene), anamnesis (reason for consultation, symptomatology, evolution), and the characteristics of the lesion (site, color, size, surface, consistency, and base). Results: Of all the tumors studied, 53% were histologically diagnosed…
Multiple sclerosis as first manifestation in oral and facial area: presentation of four cases.
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system, whose etiology is unknown, and which is characteristic by the appearance of a diverse neurological symptomatology consisting of outbreaks or gradual deterioration and lesions in any location of the brain?s white matter which may provoke the after-effect of a definitive demyelination of the area. The disease affects young people, with its appearance being most frequent between 20 and 40 years of age, in temperate and cold climates, and with a man-woman rate of 0.46 / 0.67. The magnitude of this disease lies in the fact that it is the primary cause for permanent disablement among young adults. We are pres…
