Anatomical and anthropological study of hyoid bones could be used in the sex prediction from skeletal remains. The aim of this study is to examine the morphometrical parameters of the hyoid bone individuals of the Iranian population. The study was carried out on 248 hyoid bones taken from cadavers Referred to Kahrizak Legal Medicine Center in 2020. Four anthropometric indices of hyoid bone were studied and have been associated with the sex and height of the individuals. The study included 179 (72.2%) males and 69 (27.8%) female cases. No significant difference was observed between the two gender groups in terms of age (P=0.678). The indexes of hyoid bones measured were compared between male and female genders, and the results show that the transverse distance between the tubercle of the greater horn, the Anterior/posterior dimension of the body, the distance between the upper and lower margin of the body in the middle (height) and the maximum depth of concavity on the posterior surface of the body, was associated with the sex determination (P<0.001). The four hyoid bone indexes measured in this study were higher in males compared with females, which indicates that hyoid bone morphometry can be used for sex determination in the Iranian population.

Background: Carbon monoxide (CO) poisoning is the leading cause of death as a result of poisoning. Objective: This study aimed to investigate the epidemiology and prevalence of CO poisoning in Mazandaran province from 2016 to 2018. Methods: This is a descriptive-analytical and retrospective study on the information obtained from the files of the deceased individuals who died because of CO poisoning in the forensic medicine department of Mazandaran province during the years 2016 to 2018. Results: In this study, 83 deaths due to CO poisoning were recorded. 32.5% of these people were over 50 years old, 81.9% of them were men, and 61.4% of them were married. The level of education in 92.8% of them was reported to be less than a bachelor's degree and the bedroom (66.3%) was the main place of poisoning. 56.6% of these poisonings were due to city gas poisoning and 56.6% of deaths were reported as groups death. The bruises color was rosette in 53% of the deaths. The carboxyhemoglobin levels in most of them were +2 (63.9%) and most deaths occurred in January (19.3%). The age group, source of CO, place of poisoning, carboxyhemoglobin level, education level, and the month of poisoning was significantly different among these three years. Conclusion: CO poisoning is still a substantial public health issue. City gas is defined as the main source of CO poisoning. Low educational level was related to CO deaths. Raising the awareness of the people can reduce the number of Co poisoning cases in the Mazandaran. [ABSTRACT FROM AUTHOR]

Introduction: Job satisfaction is a main factor to increase efficiency, productivity, and individual satisfaction in the organization. The purpose of this study is to determine the forensic expertise amount of job satisfaction and to compare them with other specialists in different. Materials and Methods: In this cross-sectional study, 150 individuals were included in three groups of specialists including forensic, internal medicine, and pediatric. Data were collected by Brayfield and Rothe Job Satisfaction Questionnaire. SPSS software version 23 was used for statistical analysis. Results: High levels of job satisfaction among forensic professionals were higher than low job satisfaction, but the same was true for the other two groups. In this study, job satisfaction status in the three groups of specialists was not significantly correlated with their type of expertise (P = 0.19). There was no significant relationship between job satisfaction and gender (P = 0.19). In addition, the mean age of the specialists with low and high job satisfaction was not significantly different (P = 0.99). In this study, although the mean of work experience in professionals with high job satisfaction was higher than those with low job satisfaction, this difference was not significant (P = 0.23). Conclusion: The results of this study showed that job satisfaction was high among forensic medical professionals and was not significantly different from other specialist groups including pediatric and internal medicine. In addition, job satisfaction was not significantly different in terms of age, gender, and work experience. [ABSTRACT FROM AUTHOR]

Background Gender determination from skeletal remains is one of the primary factors in forensic medicine. This study aimed to identify the gender of patients referred to the radiology ward of the Rasoul Akram Hospital of Tehran using anteroposterior pelvic radiography. Methods A total of 200 patients (100 male and 100 female) referred to the radiology ward of the Rasoul Akram Hospital for anteroposterior pelvic radiography during 2013–2014 were included in this study. After taking a standard radiographic image of all patients in the supine position and an anteroposterior view of the pelvis, factors including subpubic angles, pubic angle, X angle, ischiopubic index, ratio of the length of the symphysis pubis to the mid and minimum width of the pubis body, and ratio of the length of the symphysis pubis to the minimum width of the pubic superior ramus were measured on radiographs. The Student t test and receiver operating characteristic curve were used to compare the data of male and female patients. Values were significant at p < 0.05. Results All the evaluated variables were significantly different in male and female patients ( p = 0.000), with the highest level of measurement accuracy noted in the subpubic angle, Pubic Angle 1, X angle, Pubic Angle 2, minimum width of the pubic superior ramus, and ischiopubic index. Length of the symphysis pubis, length of the pubis, and ratio of the length of the pubis to the minimum width of the pubic superior ramus showed the lowest accuracy. Conclusion The results of this study revealed that the evaluation of the radiographic images of pelvic bones by assessing the mentioned factors can be useful for sex determination from skeletal remains. However, ethical considerations should also be taken into account while using these factors. [ABSTRACT FROM AUTHOR]

Background: Determining the association between mechanism of trauma, and the type of spine column fracture is a useful approach for exactly describing spine injury on forensic medicine field. We aimed to determine mechanism of trauma based on distribution of the transition of spinal column fractures.Methods: This cross-sectional survey was performed on 117 consecutive patients with the history of spinal trauma who were admitted to emergency ward of Rasoul-e-Akram Hospital in Tehran, Iran from April 2015 to March 2016. The baseline characteristics were collected by reviewing the hospital recorded files.Results: With respect to mechanism of fracture, 63.2% of fractures were caused by falling, 30.8% by collisions with motor vehicles, and others caused by the violence. Regarding site of fracture, lumbosacral was affected in 47.9%, thoracic in 29.9%, and cervical in 13.7%. Regarding type of fracture, burst fracture was the most common type (71.8%) followed by compressive fracture (14.5%). The site of fracture was specifically associated with the mechanism of injury; the most common injuries induced by falling from height were found in lumbosacral and cervical sites, and the most frequent injuries by traffic accidents were found in thoracic site; also the injuries following violence were observed more in lumbar vertebrae. The burst fractures were more revealed in the patients affected by falling from height and by traffic accidents, and both burst and compressive fractures were more observed with the same result in the patients injured with violence (p = 0.003).Conclusion: The type of spine fracture due to trauma is closely associated with the mechanism of trauma that can be helpful in legal medicine to identify the mechanism of trauma in affected patients.
