Background: Oral squamous cell carcinoma is a major health issue worldwide. Screening and early diagnosis are the key elements for the better prognosis of potentially malignant oral disorders. Objectives: This study establishes the effectiveness of fluorescence imaging device in the early detection and precise examination of the normal-appearing oral mucosa of tobacco chewer patients in white light and fluorescence light. Materials and Methods: The study consists of a total of 150 patients equally categorized into frequent tobacco chewers with normal mucosa, precancerous lesion, and cancerous lesion. Out of which 10 cases were excluded due to technical errors and consent-related issues. The correlation between examined oral mucosa under white light and fluorescence light was evaluated through a 2 x 3 contingency table Chi-square test. Results: Out of 140 participants with a positive cancer diagnosis, there are 43 and 53 patients were sensitive to white light andfluorescence light, respectively. The estimated values for sensitivity and specificity were 0.83 (95% confidence interval: 0.736-0.906) for biopsy report diagnosis. Conclusions: Although autofluorescence device plays a critical role in the diagnosis of precancerous oral mucosal lesions in the early stages, the histopathological evaluation remains the gold standard diagnostic approach for this life-threatening disease. Due to the high sensitivity of autofluorescence examination, it has a vital role in determining high-risk oral lesions (precancerous) and oral cancer in mass screening programs for the cancer-prone population.

Background: The prevention of new infections in high-risk groups is a major thrust in National AIDS Control Program. There is enough evidence that many epidemiological and behavioral determinants which make High Risk Group vulnerable to HIV transmission. The most effective means of controlling the spread of HIV is through the implementation of Targeted Interventions (TIs) efforts by which services are catered to them. Furthermore, stigma and marginalization are often linked to this population, which may lead to difficulties while accessing social and health services (SHS) due to behavioral, cultural and language barriers or lack of knowledge of the system. So, finding the sociodemographic & behavioral profile can give a breakthrough in improving the quality of life of HIV high risk groups., Material and Methods: A cross sectional study was conducted during September to December 2019 in two districts (i.e., Raipur & Durg) among HRGs of Chhattisgarh. Training cum sensitization of survey team e.g., peer educators, outreach workers, counselors, project managers prior to the survey was done for data collection., Results: A Total of 3963 HRGs were registered with TI NGOs, 3418 (86.2%) were screened. The mean age of study participants was 27.69 ± 6.1. Compliance of participation was 86.2%. HRGs were observed to have malnutrition (BMI <18.5 &> 25.0). 7 cases of Pulmonary TB were found among IDUs. Prevalence of diabetes and Hypertension was 1.2% and 1.1% respectively. Substance abuse (i.e., for Alcohol and Tobacco) was significantly higher among IDUs and FSWs., Conclusion: This study reinforces the fact that for accessing High Risk Groups and retrieval of relevant information can best be obtained by their care givers i.e., TI NGOs personnel. Also understanding the sociodemographic and behavioral profiles are central to designing targeted HIV prevention interventions for them., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Family Medicine and Primary Care.)
