Verruciform xanthoma is a very uncommon papillary growth seen chiefly in the oral mucosa. The presence of foam cells in the connective tissue papillae between the epithelial rete ridges forms the hallmark in its diagnosis. There has been wide speculation and various hypotheses put forth in explaining the etiopathogenesis of verruciform xanthoma and the origin of foam cells. This article aims to update the different hypotheses in understanding the pathogenesis of the lesion.
Background: Hepatitis B virus (HBV) infection is a major worldwide public health problem. Nearly 45% of the world's population lives in areas of high endemicity, with India being a country of intermediate endemicity. Objective: To assess the knowledge, attitude, and practices of dental students about HBV infection at a private dental institution in Mysore, Karnataka, India. Materials and Methods: A cross-sectional survey was conducted using a pretested, structured, and validated questionnaire containing 16 questions on awareness, transmission, prevention, diagnosis, treatment, vaccination status, and postexposure prophylaxis of HBV infection. Descriptive statistics were carried out along with chi-square test and contingency coefficient. Result: The response rate was 100% (n = 486). A total of 88.7% of the students knew about the transmission of HBV infection. Only 64% students were immunized against HBV. Majority of the students (91.1%) agreed for vaccination against HBV infection. Only 28.4% students knew about the postexposure treatment against HBV infection. About 58.8% students knew about the preventive measures against HBV infection. Conclusion: The overall awareness regarding HBV disease was found to be lacking among the dental students.
Aim: Globally, India accounts for the highest number of oral cancer cases. The survival rates are about 30% lower than those in developing countries. The main reason for these dismal figures is the late presentation of patients. In order to downstage oral cancer in such a scenario, screening and diagnosis at an early stage is warranted. A pragmatic approach is needed for an oral cancer screening program, hence a mobile health (mHealth) approach was used. In this approach, health workers were empowered with mobile phones with decision-based algorithm. Risk stratification of tobacco habit enables us to identify lesions associated with particular habits.
Materials and methods:A specific cohort of factory employees who predominantly had pure tobacco chewing habit was chosen to examine the effect of pure tobacco on oral mucosa. One thousand three hundred and fifty-seven subjects were screened in two phases. In the first phase, habits and oral lesions were identified and photographed. The photographs were remotely diagnosed by an oral medicine specialist and those subjects requiring biopsy were recalled for phase II. Cytology and biopsy were performed in phase II.
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.
