A Meta-analysis on efficacy of auto fluorescence in detecting the early dysplastic changes of oral cavity.

BACKGROUND: Light-based detection agents using autofluorescence may be helpful in the detection of early dysplasia, which would otherwise be misdiagnosed as nondysplastic by conventional oral examination (COE) with white light. Visually-enhanced lesion scope (VELscope) is one of such an aid used for the purpose. A meta-analysis was carried out on the sensitivity and specificity of VELscope that would enable in providing evidence of its usage in oral dysplasia. MATERIALS AND METHODS: MeSH terms such as auto florescence in oral dysplasia, VELscope, Oral ID, Identifi, in a different medical database such as PubMed, Cochrane, EBSCO, and Google scholar was carried out by four research associates. The total articles available were 242, of which, 230 were excluded based on strict criteria of randomized control trials and proper design. Finally, only 12 studies were chosen for the present analysis. Of 1643 patients from 12 studies, 1264 patients had undergone the autofluorescence examination after the COE. Only 774 patients have shown the loss of fluorescence with VELScope examination and 487 had retained the fluorescence. Biopsy was performed on 1176 patients after the autofluorescence examination in the areas where there was the loss of fluorescence. The available data were subjected to software Review Manager for analysis. RESULTS AND DISCUSSION: Of the 11 studies analyzed, majority of them showed that the autofluorescence device were sensitive enough > 0.70; however, the values of sensitivity and specificities varied significantly. With the VELscope the diagnostic performance of the inexpert examiner was not improved, obtaining a sensitivity of 0.40 (95% of confidence interval [CI]: 0.406-0.773) and a specificity of 0.80 (95% CI: 0.614-0.923). CONCLUSION: The new technique may help as an adjunct to histopathology in detecting the dysplasia initially and stop further progression to the carcinoma.

Virtopsy: Touch-free autopsy.

The word "autopsy" denotes "to see with own eyes." Autopsy (postmortem) is a process that includes a thorough examination of a corpse noting everything related to anatomization, surface wounds, histological and culture studies. Virtopsy is a term extracted from two words "virtual" and "autopsy." It employs imaging methods that are routinely used in clinical medicine such as computed tomography and magnetic resonance imaging in the field of autopsy, to find the reason for death. Virtopsy is a multi-disciplinary technology that combines forensic medicine and pathology, roentgenology, computer graphics, biomechanics, and physics. It is rapidly gaining importance in the field of forensics. This approach has been recently used by forensic odontologists, but yet to make its own mark in the field. This article mainly deals with "virtopsy" where in various articles were web searched, relevant data was selected, extracted, and summarized here.

Low Level Laser Therapy to Reduce Recurrent Oral Ulcers in Behçet's Disease.

Behçet's disease (BD) is a chronic, relapsing multisystemic vascular condition. Behçet's disease was described by Hulusi Behçet in 1937. This rare multisystem relapsing-remitting inflammatory disease is poorly understood but is thought to be an autoimmune inflammatory vasculitic process in a genetically predisposed population. Diagnosis of Behçet's disease is based on International Criteria of Behçet's Disease (ICBD). The present paper describes a case report of Behçet's syndrome where aphthous stomatitis was treated with low level laser therapy.

Knowledge and Awareness of Teledentistry among Dental Professionals - A Cross Sectional Study.

BACKGROUND: The use of technology in the form of smart phones and other electronic media in day to day life has become an integral part of life today. Technology today is seeing a paradigm shift towards better inter-professional communications which can help doctors, patients and the masses as a whole. Putting these technological advancements to good use evolves as a major milestone in medicine/ dentistry in the form of telemedicine/teledentistry. AIM: The present study was aimed at knowing the knowledge and awareness of teledentistry among dental professionals of a dental college in India. SETTINGS AND DESIGN: The study was conducted in a dental college in India and was circulated among dental professionals. MATERIALS AND METHODS: A questionnaire was prepared to assess the knowledge and awareness of teledentistry and was circulated among dental professionals in a dental college. The data thus collected was statistically analysed and results obtained. STATISTICAL ANALYSIS: The data collected was statistically analysed using SPSS software. RESULTS: A total of 406 persons responded to the questionnaire. In the present study it was found that the knowledge and awareness about teledentistry was very low among post graduates (7.23%) and interns (9.38%) when compared to I & II BDS while most of them agreed that teledentistry is a practice of dentistry through various media options with limited application in dentistry without a legal issue. CONCLUSION: In the present study, it was apparent that most of the respondents were lacking adequate knowledge and awareness on teledentistry. Hence, there is an immense need to create awareness among dental professionals on teledentistry as the future lies in technological advancement. Tele dentistry can mark the beginning of a new era in dentistry. This can be achieved by conducting CDE programs and awareness campaigns/programs which helps in various levels.

Rare Case of Spindle Cell Haemangioma.

Spindle cell haemangioma (SCH) is a benign vascular lesion which usually occurs on distal extremities. It was previously regarded as haemangioendothelioma and was initially perceived to be low grade angiosarcoma.They are characterized by cavernous blood vessels and spindle cell proliferation. It is now considered as a reactive lesion and conservative surgical excision is preferred treatment. Intraoral occurrence is rare; hence we present a case of SCH in a 33-year-old male that presented as a swelling below the tongue. Histopathology showed well circumscribed proliferating spindle cells attached to vessel walls, dilated vascular spaces. The lesion was positive for CD31 and CD34 markers suggesting it to be of endothelial cell origin.

Fulminant mucormycosis involving paranasal sinuses: a rare case report.

Mucormycosis is an opportunistic fulminant fungal infection, which has the ability to cause significant morbidity and frequently mortality in the susceptible patient. Common predisposing factors include diabetes mellitus and immunosuppression. The infection begins in the nose and paranasal sinuses due to inhalation of fungal spores. The fungus invades the arteries leading to thrombosis that subsequently causes necrosis of the tissue. The infection can spread to orbital and intracranial structures either by direct invasion or through the blood vessels. Here we describe a case of mucormycosis of maxillary antrum extending to ethmoidal and frontal sinus and also causing necrosis of left maxilla in an uncontrolled diabetic individual to emphasize early diagnosis and treatment of this fatal fungal infection.
