The mechanism is complicated and varied depending on thesituation, not only the asphyxia in submersion. It is believed as the firstproblem of public health, and early studied because of social valuation.In evaluation of WHO, the proportion of drowning is 5.6/100.000population, two third is accidental, 1/3 suicidal drowning, rarelyhomicidal drowning. Most of victims are children or young people. Vietnam is a tropical country, there are a large number of lakes andrivers, long beach which are potential for drowning, especially inhurricane season. As others countries, the most common cause isoccupational or daily activity. Others are homicidal or suicidal cause. In Military Institute of Forensic Medicine, the proportion ofdrowning is high. However, there is no research of epidemiology,pathology and victims identification. In forensic examination, there are some problems for solving: - Who is the victim? The cause of death? The cause of death isdrowning or not? Which examination or test to confirm the drowning cause? - Could the patient be identified ? Which test for identification?. In order to do so, the forensic examiner has to fully collect theprimary evidences, analysis the scene, and forensic results, incombination with proper identification method. Therefore, the study “Assessment the forensically pathologiccharacteristics and identification method of drowning victims” aims to: 1. Description of the pathologic signs and characteristics of drowning victims. 2. Application of DNA analysis in identification of drowning victims. 21. The need of the thesis The thesis is an answer for debating question regarding ofpathologic characteristics of drowning and proposes the DNA analysisfor identification method. The description study concluded the valuablepathologic signs and characteristics for diagnosis. In this study, the DNAanalysis was applied for victims identification.2. The contribution of the thesis Statistical description of general characteristics of drowning such as:conjunctivitis (100%), lividity pattern (74.6%), rigor mortis (89.4%),froth (66.4%), wrinkle skin (58.1%), exophthalmos (100%), flared mouth(78.8%), peeling skin (72%), fluid and foam in the airway (54.8%),pulmonary edema (88.5%), the foreign body in airway (35.5%), water instomach (30.8%), the laceration of aveoli (88.5%), rupture RBC invessels and organs (50%). Diatom test plays an important role indiagnosis confirmation and location of drowning. The application of DNA analysis is an appropriate method tovictims identification: there was 18.02% victims need to DNA analysisfor identification, successful identification was 100% (31/31); from 1-4postmortem days, most of victims were identified by the normal method(83.3%-84.2%); 85% victims was required the DNA analysis foridentification from 5-9 days postmortem. From 1-4 days postmortem, thenucleus analysis was used for every victim. From 5-15 postmortem, themitochondrial analysis was more preferred, After 15 days postmortem,most victims was identified by mitochondrial analysis.3. The structure of the thesis The thesis includes 108 pages. General description (02 pages),Conclusion (02 pages), and proposal (01 page). Four chapters : Chapter1 : General description (31 pages), Chapter 2 : Objects and Methodology(13 pages), Chapter 3: Results (22 pages), Chapter 4: Discussion (37pages). It also includes 26 tables, 04 images, 09 charts, 73 referencematerials, study form and victims list, the image illustrates. 3 ...
