Elevated tissue nitric oxide in oral squamous cell carcinoma.

Context: Nitric oxide (NO) is a diatomic molecule that has been implicated in tumor progression of oral squamous cell carcinoma (OSCC). However, the mechanism of NO affecting tumor growth and progression remains unknown. Tumor progression has been recently received considerable attention, and there is increasing evidence of correlation of tumor biology and behavior.

Juvenile nasopharyngeal angiofibroma.

Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign tumor arising predominantly in the nasopharynx of adolescent males. It is an aggressive neoplasm and shows a propensity for destructive local spread often extending to the base of the skull and into the cranium. Clinically, however, it is obscure with painless, progressive unilateral nasal obstruction being the common presenting symptom with or without epistaxis and rhinorrhea.

Van der Woude syndrome with an unusual intraoral finding.

Orofacial manifestations of Van der Woude syndrome (VWS) include cleft lip or palate, lower lip pits, hypodontia, hypernasal voice, cleft or bifid uvula, syngnathia, narrow high arched palate, and ankyloglossia. Extraoral manifestations include limb anomalies, popliteal webs, accessory nipples, congenital heart defects, and Hirschsprung disease. We report an interesting case of VWS with characteristic orofacial features along with an unusual additional finding of fusion of primary mandibular left lateral incisor and canine in a 7-year-old boy.

Role of forensic odontology in the world's major mass disasters: facts and figures.

Unlabelled: Forensic identification of the victims in mass disasters is essential, not only for humanitarian reasons, but also for civil or criminal investigative need. The number of victims identified with the help of forensic odontology in various mass disasters in the world has been analysed and discussed. The result depicts the necessity of keeping proper dental records at institutional and individual level.
