This study aimed to evaluate the cause and burn patterns in self-immolated patients referred to Shahid Motahari Trauma and Burn Hospital in Tehran, Iran. </span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:16.0pt"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:9.0pt">Materials & Methods</span></i></b><b><span style="font-size:9.0pt">:</span></b><span style="font-size:9.0pt"> This cross-sectional study was conducted on 282 patients who were hospitalized, due to self-immolation, in the above-mentioned hospital between 2014 and 2020. During the study, information such as patients&rsquo; demographic data, burn percentage, burn grade, and organs involved due to self-immolation, duration of hospitalization, and infection and mortality rates following self-immolation were recorded. </span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:16.0pt"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:9.0pt">Results</span></i></b><b><span style="font-size:9.0pt">:</span></b><span style="font-size:9.0pt"> The mean age of self-immolated people was 35.5 &plusmn; 12.5 years, and the majority were male (58.2%) and married (61.7%) with non-university education (89.7%) and poor financial status (90.4%). Most of the patients (94%) had used caustic agents. The cause of self-immolation in 84% of people was family disputes and in 13.4% mental illnesses, and 51.1% finally died. The gender of the patients had a statistically significant relationship only with marital status (P = 0.001) and whole-body burns (P = 0.01). </span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:16.0pt"><span new="" roman="" style="font-family:" times=""><b><i><span style="font-size:9.0pt">Conclusion</span></i></b><b><span style="font-size:9.0pt">: </span></b><span style="font-size:9.0pt">According to our findings, self-immolation is prevalent in men, especially in upper limbs, and the most common cause of self-immolation is family disputes. Self-immolation mostly results in grade 3 burns in both genders. In the hospital, infection after burn is of great importance; therefore, prevention and control measures of nosocomial infection are necessary.</span></span></span></span> Burn Pattern, Self-Immolation, Suicide 82 89 http://hsm.umsu.ac.ir/browse.php?a_code=A-10-143-1&slc_lang=en&sid=1 Siamak Soltani azadeh.memarian.fornsic@gmail.com 10031947532846001422 10031947532846001422 No Department of Forensic & Legal Medicine, School of Medicine, Rasoul Akram hospital,Iran University of Medical Sciences, Tehran, Iran Azadeh Memarian azadeh.memarian.fornsic@gmail.com 10031947532846001423 10031947532846001423 Yes Assitant of Clinical Toxicology,Shahid Beheshti University of Medical Sciences, Associte professor,Department of Emergency Medicine, Faculty of Medicine, Mazandaran University of Medical Sciences, Sari, Iran Kamran Aghakhani azadeh.memarian.fornsic@gmail.com 10031947532846001424 10031947532846001424 No Department of Forensic & Legal Medicine, School of Medicine, Rasoul Akram hospital,Iran University of Medical Sciences, Tehran, Iran Leyla Abdolkarimi azadeh.memarian.fornsic@gmail.com 10031947532846001425 10031947532846001425 No Shahid Rajaei Cardiovascular Medical and Research Center, Tehran, Iran Farrokh Taftachi azadeh.memarian.fornsic@gmail.com 10031947532846001426 10031947532846001426 No Shahid Rajaei Cardiovascular Medical and Research Center, Tehran, Iran
