Acridine Orange Fluroscence Study of Lung - Histopathology in Autopsy Cases of Burns

Background: The major cause of death in the burn patients includes multiple organ failure and septicemia but, sometimes the exact cause of death in many fatally burn patients is difficult to detect. Aim: The aim was to study various histopathological changes in lung in the post-mortem cases of burns, by using routine Haematoxylin and Eosin stain (H&E stain). Periodic and Schiff ’s Stain (PAS) stain to study the role of acridine orange fluorescence study, to explore the forensic utility of this study and to find out the relationship between duration of survival and histopathological changes observed. Material & Methods: Total 32 cases of death due to burns were autopsied at mortuary from october 2010 to september 2012, department of Forensic Medicine and Toxicology in our hospital. These were forwarded to Department of Pathology for histopathological examination. Result: In the present study, maximum number of burns cases in 21-30 years of age group & female predominance. Grossly, 19 cases (59.38%) showed congestion while microscopy showed diffuse alveolar damage (34.38%). The sections stained by acridine orange and observed under fluorescent microscope were negative in 28 cases (87.50%) and lightly positive in 04 cases (12.50%). Conclusion: Routine microscopy does help us in getting specific lesions in lung due to burns. But PAS and Acridine orange fluorescence do not add anything further in our knowledge of pathology due to burns. However, none of these add any new tool to resolve any forensic issues of burns. Therefore, microscopy (including PAS and fluorescent), if done would be redundant
