Biodosimetric analysis of head and neck cancer patients undergoing radiotherapy by dicentric chromosome aberration assay.

Background: Biodosimetry is the quantification of absorbed radiation dose using biological material obtained from an exposed individual. Radiation can cause different types of chromosomal aberrations, including stable aberrations like translocations and unstable ones like micronuclei, dicentric chromosomes (DC), acentric, and ring forms. Dicentric chromosome assay has become the "gold standard" for cytogenetic biodosimetry due to its reproducibility, specificity (low baseline rates), and sensitivity to low doses.

Late onset Wilson Disease with normal neuro-psychiatric status: A case report.

Introduction: Late onset Wilson disease (WD) is a rare form of WD. WD has variability of clinical presentations from acute liver failure to chronic liver disease (CLD). The hepatic and neurological variants of WD have wider variations.

Salivary metabolite signatures of oral cancer and leukoplakia through gas chromatography-mass spectrometry.

Background: Saliva contains a large array of metabolites, many of which can be informative for the detection of diseases. Gas chromatography-mass spectrometry (GC-MS) is a system that has long been used for metabolite profiling owing to its sensitivity, specificity, reproducibility and synchronized analysis; it has relatively broad coverage of compound classes including sugars, sugar alcohols, glycosides and lipophilic compounds.

Aim And Objectives: The present study was conducted to explore the use of GC-MS in assessing variation in salivary metabolites and to recognize the metabolites which can be used as disease diagnostic tools and metabolite markers for detection of oral squamous cell carcinoma.

Highly aggressive gastric adenocarcinoma with multiple skin nodule and supraclavicular node in a 19-year-old patient: A rare presentation in such young age.

Although gastric adenocarcinoma is common in middle- and old-aged population, it is rare in young people. Development of cutaneous metastasis during presentation is even rarer in any age group. We report the case of a 19-year young man with gastric adenocarcinoma who had multiple skin nodules over the trunk during presentation.
