      Pig half-carcasses were shot in scapulae, ribs and mandibles with either 0.243 hunting rifle using high velocity expanding ammunition (N = 30) or AK47 using full metal jacketed (FMJ) ammunition (N = 12) from a range of either 5 or 20 m. Fracture patterns related to distance of fire and ammunition type were compared on de-fleshed, macerated, and reconstructed bones. For expanding ammunition, location of fracture on ribs affected the resulting pattern. Scapulae shot from 5 m presented a comminuted pattern different from those shot from 20 m. Mandibles shot from 20 m showed a characteristic radiating pattern at entrance with the opposite ramus un-fractured; those shot from 5 m exhibited fractures to both rami. Using decision tree analysis provided accuracies of 93.8% for scapulae and 87.5% for mandibles. For FMJ, no distance dependent fracture differences were apparent in any bone. Decision tree analysis facilitated the interpretation of fracture patterns caused by projectile trauma.

      Background There are many studies of bunk bed injuries, but none specifically addressing those occurring in jails. It was the purpose of this study to investigate the magnitude and patterns of bunk bed injuries occurring in correctional institutions. Methods The National Electronic Injury Surveillance System (NEISS) data for the 10 year period 2006 through 2015 due to bunk beds was accessed. Injuries involving bunk beds were identified and the mechanism of injury determined. Statistical analyses were performed with SUDAAN 10™ software. A p < 0.05 was considered statistically significant. Results There were an estimated 639,505 ED visits for bunk bed associated injuries; 51,204 occurred in jail. All jail cases occurred in the age groups ≥10 years (177,165); 29% of these 177,165 sustained the injury in jail. Those who sustained a bunk bed injury in jail compared to those who did not were older, more commonly male, seen in smaller hospitals, more likely admitted, and more frequently associated with a seizure. For those injuries occurring in jail, the most common injury in the trunk and lower extremity was a strain/sprain; the upper extremity a contusion/abrasion; and the head/neck a laceration or traumatic brain injury. A fall off the bunk bed accounted for 71.8% of the injuries, had the highest hospital admission rate (7.4%), accounted for all of the spine injuries, 96% of the head injuries, and had the highest proportion of fractures (14.4%). Inmates having a seizure before the injury sustained fewer fractures, more lacerations, and more head/neck injuries. Conclusions Injuries in jail account for 29% of all bunk bed injuries resulting in an ED visit in the USA in those age groups ≥10 years. A fall from the bed occurred in 72% and a seizure disorder was 4.5 times more common in jail inmates compared to non inmates. Possible prevention strategies include railings/ladders to reduce the incidence of falls, changes in flooring surfaces, and seizure education and placing inmates with seizure and/or alcohol related disorders on the bottom bunk. This will require a multidisciplinary approach involving the disciplines of medicine, material engineering, and criminal justice.

      Objective The aim of this article was to assess the effects of child sexual abuse (CSA) on emotion regulation (ER) in adolescents and to evaluate the relationships between non suicidal self-injury (NSSI), emotional eating, insomnia and emotion disregulation (ED). Method Fifty two adolescents, aged 10–18 years, without who weren't diagnosed a psychiatric disease before abuse and completed 6-months of follow-up after abuse included the study. Control group consisted of 33 healthy voluntary participants without any known psychiatric disorders. Patients and volunteers who participated in the study were assessed with the Inventory of Statements About Self-injury (ISAS), Dutch Eating Behavior Questionnaire (DEBQ), Pittsburgh Sleep Quality Index (PSQI), Insomnia severity index (ISI), and the Difficulties in Emotion Regulation Scale (DERS). Results In our study, PSQI scores, DERS total scores and DEBQ emotional eating subscores were significantly higher in the CSA victims (In orderly; p = 0,034, p < 0.001, p = 0,023). 55.7% of the CSA victims reported self-injurious behavior, while 15.5% of healthy voluntary participants reporting self-injurious behavior. The CSA victims reporting NSSI had higher DERS scores than CSA victims without NSSI. (p = 0.024). The CSA victims with post-traumatic stress disorder (PTSD) and CSA victims without PTSD had a positive correlation between DEBQ emotional eating subscores and DERS total scores (In orderly: r = 0.762, p = 0.031; r = 0.872, p < 0.001). There was a positive correlation between the PSQI scores and DERS scores in the CSA victims with PTSD (r = 0.827, p = 0.023). Conclusion Further studies are needed to assess the relationship between self-injury, emotional eating, insomnia and ED, and to determine how sexual abuse effect the ER in a clinical sample of CSA.

      The main goal of this study was to evaluate the association between daily cases of hanging suicides and meteorological conditions in São Paulo, Brazil. We considered a retrospective observational study based on the analysis of all necroscopic medical-expert reports available in digital form from the central unit of the Instituto Médico Legal (Medical Legal Institute) of São Paulo between July 1, 2006 and June 31, 2007. The meteorological variables were combined via Principal Components Analysis. In order to explain their association with the frequency of suicides, Poisson regression models were employed. The analysis suggests that hotter and brighter days are associated with higher incidence of hanging suicides.

      There is inevitable need for data regarding anthropometric measurements of each community's population. These anthropometric data have various applications, including health assessment, industrial designing, plastic & orthopedic surgery, nutritional studies, anatomical studies and forensic medicine investigations. Anthropometric parameters vary from race to race throughout the world, hence providing an anthropometric profile model of residents of different geographic regions seems to be necessary. To our knowledge, there is no report of bone parameters of the Iranian population. The present study was carried out to provide data on anthropomorphic bone parameters of the Iranian population, as a basis for future relevant studies. We calculated most of the known anthropometric parameters including skull, mandible, clavicle, scapula, humerus, radius, ulna, sacrum, hip, femur, tibia and fibula of 225 male corpses during a period of 2 years (2014–2016). Data expression was done as mean ± standard deviation. The results consist the first documented report on anthropometric bone measurement profile of Iranian male population, that can be considered a valuable source of data for future research on Iranian population in this regard.

      Histological studies of healed bone tissue following amputation are relatively rare in the literature. This study describes the histomorphological features of femoral thin sections from six uni- and bi-lateral amputees of documented age and sex. Thin sections were cut from the midshaft of both the right and left femora from each amputee and analyzed following standard forensic methods for histological estimation of age at death from the human femur. The histological age at death estimations for the thin sections from amputated bone were consistently lower than the actual chronological age of each individual, suggesting that the effects of amputation prohibit the effective use of age at death estimation methods. The nature of each amputation is unknown, which suggests that alternative factors could be responsible for the slowed bone turnover seen in the thin sections from the amputated bone. First, it is reasonable to assume that the amputations in this sample could have resulted from complications of diabetes mellitus rather than trauma so the possible effects on bone remodeling due to disease are explored. Second, the mobility of the decedents following their amputations is unknown so the histomorphological results could be due to disuse osteoporosis.

      The General Medical Council (United Kingdom) advocates development of non-core curriculum Student Selected Components and their inclusion in all undergraduate medical school curricula. This article describes a rationale for the design, delivery, assessment and evaluation of Student Selected Components in Forensic and Legal Medicine. Reference is made to the available evidence based literature pertinent to the delivery of undergraduate medical education in the subject area. A Student Selected Component represents an opportunity to highlight the importance of the legal aspects of medical practice, to raise the profile of the discipline of Forensic and Legal Medicine amongst undergraduate medical students and to introduce students to the possibility of a future career in the area. The authors refer to their experiences of design, delivery, assessment and evaluation of Student Selected Components in Forensic and Legal Medicine at their respective Universities in the Republic of Ireland (Galway) and in the United Kingdom (Oxford).

      Excessive alcohol consumption is a serious public health issue, because drunkenness affects critical judgment and self-control which could trigger violent and self-harm behavior, with thus a potential association between alcohol consumption and suicide deaths. The objective of the present study was to assess the association between alcohol consumption and suicide deaths in the city of Sao Paulo, Brazil, from 2011 to 2015, and its relationship with socio-demographic characteristics of the victims and the circumstances of the suicide. A cross-sectional retrospective study was conducted by collection of data from 1,700 suicide victims subjected to examination of blood alcohol concentration (BAC) from toxicology reports from the Institute of Legal Medicine of the State of Sao Paulo, Brazil. Alcohol was detected in blood samples of 30.2% of the victims and mean BAC levels were 1.73 ± 0.08 g/L. The mean age of the victims was 39.90 ± 0.75 years. The majority of the victims were male (74.6%) and the prevalence of positive BAC was higher amongst men (34.7%) than women (17.1%), p<0.05. The majority of the victims were white skinned (64.7%), but there was a higher proportion of victims with positive BAC among mulatto and black individuals, p<0.05. Hanging was the most prevalent suicide method in the sample (48.7%) and amongst men (55.4%), but amongst women it was jumping from a height (35%), p < 0.05.

      Introduction Determining the time of death of bodies recovered from water can be difficult. A feature of drowning is the presence of external foam. This study describes the presence of external foam in relation to the post-mortem period. Method The study utilizes a database of death reports dated between January 2011 and July 2016. For bodies recovered from fresh water, the presence or absence of external foam was noted. Results In this study, 112 death reports are included. Of these reports, 18 mentioned external foam, which account for 16.1% of the entire study population. In the population with a post-mortem period of less than 24 h, external foam was detected in 27.7% of cases. All 18 incidents with external foam had an estimated post-mortem period of less than 24 h. Conclusion In our study, external foam was only present in freshwater drowning cases with a post-mortem period of less than 24 h. Based on this finding, the presence of external foam may be useful as an additional indicator when estimating the time of death in freshwater drowning.

      Purpose The objectives of this study were to describe fracture morphology resulting from common loading mechanisms such as bending and torsion in immature bone and to identify differences in the energy required to produce various fracture types under these two loading mechanisms using an immature porcine animal model. Methods Twenty-six in vitro immature porcine femora were mechanically tested in 3-point-bending and torsion. Femur specimens were tested with and without soft tissue and at both quasi-static and dynamic loading rates. Bone geometry and density measures were determined for each femur using dual-energy x-ray absorptiometry and plain film x-rays. Failure load, stiffness, and energy to failure were determined for each specimen from the load-displacement history from mechanical tests. Results 3-point bending tests resulted in 10 transverse fractures and 2 oblique fractures. Torsion tests resulted in spiral fractures. Mean energy required to produce transverse fractures (3.32 Nm) was double that associated with spiral fractures (1.66 Nm). In bending, specimens with soft tissue intact required significantly greater energy to fracture (4.40 Nm) than specimens with soft tissue removed (2.92 Nm). Torsional loading rate did not significantly affect energy to fracture. Conclusions Fracture morphology is dependent upon loading conditions. Energy to failure allows for comparison across various loading conditions, and thus offers an effective means of characterizing fracture thresholds for a wide range of scenarios. Consideration should be given to whether or not soft tissue is left intact when conducting experiments using whole bone specimens given its influence on energy to failure.

      Old age should be examined separately from other stages of life in terms of ratio, method and motives for suicide. With some variation, epidemiological studies suggest suicides increase with age in virtually every society. This study examines demographic data (age, sex and marital status), and other factors related to 20-years (1997–2016) of completed elder suicides in Eskisehir, Turkey. The 74 cases of those 65 and over were evaluated with regard to method, tool and location of the suicide. Annual distributions illustrate gradual increases in this fatal self-harm over time. The vast majority of cases were male (74.3%), compared to female (25.6%). Elders in the 80–84 age range were most likely to kill themselves. Deaths were frequently caused by hanging, followed by other methods and took place in the home. Reasons associated with suicidal behavior included despair as a result of bereavement, mental illnesses, chronic physical conditions and living alone. The researchers cite potential prevention strategies through the use of early mental health treatment for elders, along with inclusion in social services and activities.

      The exposure time of carcasses in insect succession studies are generally not consistent and more than 40% studies start in the morning. How such an arrangement affects the succession of insects is worth evaluating. In this study, six piglet carcasses (15–17 kg) were exposed at 6 time points during the day: 11:00, 15:00, 19:00, 23:00, 03:00 and 07:00 on July 20th-July 21st 2006 in Guangzhou, China to investigate the potential effects of the time of day of carcass exposure on body decomposition and insect succession, and also to provide fundamental data on insect succession in summer for this area. The results showed that there were negligible differences in the decay process among the carcasses. We found the carcasses synchronized their decay stage after entering the bloated stage on July 21st. All 6 carcasses entered the remains stage on August 3rd (approximately 14 d after carcass placement). The carcasses yielded 30 species of arthropods, representing 3 orders and 12 families, and no obvious differences were found in species composition between the carcasses. However, we found that there were significant differences in the arrival and colonization of Calliphoridae. We found two batches of Chrysomya megacephala (Fabricius) larvae with significant differences in body length and instar on the carcasses placed at the site at 11:00, 15:00 and 19:00. By contrast, there was only one batch of C. megacephala larvae having similar body length and instar on the carcasses placed at the site at 23:00, 03:00 and 07:00. These observations have potential use for estimating the postmortem interval in forensic entomology.

      Forensic evidence often relies on a combination of accurately recorded measurements, estimated measurements from landmark data such as a subject's stature given a known measurement within an image, and inferred data. In this study a novel dataset is used to explore linkages between hand measurements, stature, leg length and stride. These three measurements replicate the type of evidence found in surveillance videos with stride being extracted from an automated gait analysis system. Through correlations and regression modelling, it is possible to generate accurate predictions of stature from hand size, leg length and stride length (and vice versa), and to predict leg and stride length from hand size with, or without, stature as an intermediary variable. The study also shows improved accuracy when a subject's sex is known a-priori. Our method and models indicate the possibility of calculating or checking relationships between a suspect's physical measurements, particularly when only one component is captured as an accurately recorded measurement.

      Background The yew (Taxus baccata) is a common evergreen tree containing the toxin taxine B. Between 42 and 91 g of yew leaf is lethal to a 70-kg adult. The objective of this article is to present an overview of findings in fatal yew intoxications. Methods A search using MeSH terms was performed in PubMed for yew intoxications in the period between January 1960 and August of 2016. Results We describe a total of 22 cases. Fatal intoxications can be divided into intoxications by leaves, by pulp, by bark and by yew tea. Recognizing yew tea intoxication is difficult since tea no longer contains any botanically recognisable parts. In autopsy and external examination no characteristic findings are reported, regarding the presence of parts of plants. Conclusions Indications for yew tree intoxications at a post-mortem examination and autopsy are limited to finding parts of yew tree. The absence of recognisable parts can result in yew intoxications being overlooked. Therefore toxicological screening is recommended in unexplained deaths.

      Purpose The aim of this study was to compare pathological findings after traumatic brain injury between autopsy and ante-mortem computed tomography (CT). A second aim was to identify changes in these findings between the primary posttraumatic CT and the last follow-up CT before death. Methods Through the collaboration between clinical radiology and forensic medicine, 45 patients with traumatic brain injury were investigated. These patients had undergone ante-mortem CT as well as autopsy. During autopsy, the brain was cut in fronto-parallel slices directly after removal without additional fixation or subsequent histology. Typical findings of traumatic brain injury were compared between autopsy and radiology. Additionally, these findings were compared between the primary CT and the last follow-up CT before death. Results The comparison between autopsy and radiology revealed a high specificity (≥80%) in most of the findings. Sensitivity and positive predictive value were high (≥80%) in almost half of the findings. Sixteen patients had undergone craniotomy with subsequent follow-up CT. Thirteen conservatively treated patients had undergone a follow-up CT. Comparison between the primary CT and the last ante-mortem CT revealed marked changes in the presence and absence of findings, especially in patients with severe traumatic brain injury requiring decompression craniotomy. Conclusion The main pathological findings of traumatic brain injury were comparable between clinical ante-mortem CT examinations and autopsy. Comparison between the primary CT after trauma and the last ante-mortem CT revealed marked changes in the findings, especially in patients with severe traumatic brain injury. Hence, clinically routine ante-mortem CT should be included in the process of autopsy interpretation.

      Foot impressions are of utmost importance in crime scene investigations. Foot impressions are available in the form of barefoot prints, sock-clad footprints, and as impressions within footwear. Sometimes suspects leave their footwear at the crime scene, and the insole of this footwear may contain the foot impression of the suspect which may be important evidence linking him or her to the crime. The task of identification based on the analysis of footprints can be challenging when the footprints belonging to one of the identical twin is available for examination. The present study is based on the quantitative measures of the foot impressions in the footwear of adult identical twins. The study was conducted on four sets of female monozygotic twins from the United States of America. A total of 17 length and breadth measurements were taken on each foot impression. A combination of Reel Method and Extended Gunn Method was utilized to produce the measurements. The measurements of the foot impressions were compared among the twins on the right and the left side. Differences were found in the various footprint measurements among the twins. The study's sample size was not large enough to apply robust statistical tests, but the study is significant in that it presents the first detailed comparative analysis of a large number of measurements of insole foot impressions of adult twins. The observations derived from the study are likely to assist forensic investigations in cases involving the foot impressions of the twins.

      Dental age (DA) has been widely accepted as a way to evaluate chronological age (CA) in recent years. However, the applicability of Willems method, as one of the most popular radiographic ways, still remains controversial in different areas. The aim of this study is to assess the difference between DA and CA with Willems method. Relevant studies published up to February 28th, 2017 were selected via PubMed, Embase, the Cochrane Library, CNKI, CBM and manual search. Studies that examined Willems dental age and chronological age were selected. 11 articles with 9347 individuals whose age ranged from 3.0 to 18.9 years old were ultimately included in this study. The general polled data indicated that Willems method overestimated CA by 0.18 years and 0.06 years for males and females respectively. Subgroup analysis for ethnicity showed significant difference for different ethnicities. Our aggregated data demonstrated that Willems method may not be an overall applicable tool to estimate chronological age for the reason of the difference of ethnicity and rational validity is suggested when necessary.

      Background Since decades, Forensic Medicine is mainly taught by didactic methods but in last couple of years some other teachinglearning and assessment methods are also introduced at some places which also lacks uniformity. Feedback from learners is most fundamental aspect to assess effectiveness of applied methods, but is not implemented in practice at most medical schools in India. Unfortunately, medical students are deprived of this practical empowerment and thus may not be efficient enough to contribute potentially to the justice system during their professional life. In order to improve their efficiency in the field, we introduced few innovative teaching-learning methods and documented their perceptions. Materials and Methods This pilot study was carried out with students who had completed their second professional year (5th semester) of medical curriculum. Students were exposed to few innovative teaching-learning and assessment approaches in addition to conventional methods during their Forensic Medicine term. These approaches were interactivity in large group lecturing, small group activities, student led objective tutorial, court visit in real scenario, practical records book, surprise tests, structured theory question papers, model answers, objective structured practical examinations and structured oral viva. Their perceptions were documented later through structured questionnaire. Results Students reported all methods as 'interesting' except 'surprise tests'. Court visits were rated highest for generating interest (98%). Clarity of concept was experienced through all methods (range of 71–95%). Interactive large group lectures reported highest (by 95%students) for clarifying concepts, although this is not a typical characteristic of large group teaching. Enhanced learning experience was reported in 75–92.5% for different methods. Student Led Objective Tutorials seemed to facilitate enhance learning most (92.5%). Conclusion Innovations in teaching-learning are need of hour especially in subject like Forensic Medicine which has direct implications to add into administration of justice in the court of law. This pilot study has given us ideas for making teaching-learning and assessment more student centric considering emerging societal needs.

      Introduction Clinical and forensic autopsies are the best methods for determining cause of death. The aim of this study was to determine demographic and etiologic characteristics in geriatric forensic cases analyzed in Erzurum, Turkey. Materials and methods Autopsy reports and prosecution documents of decedents aged 65 and older autopsied in the Morgue Specialization Department of the Forensic Medicine Institute, Erzurum Division between January 1, 2010 and December 31, 2015 were screened retrospectively. Results The study included 399 subjects with a mean age of 74.38 ± 7.28 years. A large proportion of the subjects were in the young and middle old age group (n = 218, 54.63%) and male (n = 286, 71.68%). Autopsy was performed on 198 (49.62%) of the subjects, cause of death was determined by post-mortem external examination in 199 (49.87%), and documents were unavailable for 2 subjects. Cause of death was determined as natural in 130 (32.58%) of the decedents and unnatural in 269 (67.42%). The most common natural cause of death was cardiovascular disease (n = 94, 76.4%). Unnatural causes of death included accident in 223 (82.90%), suicide in 25 (9.30%) and homicide in 21 (7.80%) of the decedents. A large proportion of the accidents were traffic accidents (n = 120, 53.80%). The most common method of committing suicide was hanging (n = 15, 60%), whereas homicides were most often committed by blunt force trauma (n = 9, 42.86%). Conclusion Our data are consistent with the literature, allowing for some variation based on regional sociocultural characteristics.

      Sexual and family violence are highly prevalent problems with numerous negative health consequences. Assault centres, such as the Centre for Sexual and Family Violence (CSFV) in the Netherlands, have been set up to provide optimal care to victims. We wanted to gain insight into characteristics of the population that presented to the Centre in order to customize care to their needs. File analysis was conducted of victims who attended the CSFV between 2013 and 2016. Data were analyzed in SPSS. A total of 121 victims entered the Centre, 93% of them being female. Forty-two per cent were adult victims of sexual violence, 28% minor victims of sexual violence and 30% adult victims of family violence. One-third of sexual and two-third of family violence victims had experienced prior abuse. Current use of psychosocial services and psychiatric medication was high, and a cognitive disability was present in 18% of the sexual violence victims. Half the victims reported, but when the perpetrator was a recent contact, e.g., someone met at a party, reporting rates went down. Sexual and family violence victims share characteristics that indicate vulnerability, suggesting that care for both groups might best be combined in one single assault centre. In this way, victims can make use of the same services and knowledge of gender-based violence. One of the major aims of assault centres is to provide psychosocial follow-up care and facilities for reporting. The victims' needs in these matters deserve further research.

      The study of carrion fauna associated with buried human corpses from a forensic perspective could provide useful information in criminal investigations. Insects and other arthropods remains sampled of 44 legally exhumed infant skeletons from La Plata (Buenos Aires, Argentina). They were identified at different taxonomic levels depending on the state of preservation. The specific diversity, abundance and frequency were analyzed and each taxon was assigned to the hypothetical colonization sequence: burial colonization, post-exhumation contamination at cemetery deposit or soil fauna. The phorid Dohrniphora sp. is mentioned for the first time in Argentina as carrion fauna of underground colonization, and the assemblage of Dohrniphora sp., Megaselia scalaris and Hydrotaea aenescens is proposed as indicator of buried cadavers. These findings provide new useful data to be applied in forensic entomology research.

      Objective In recent years, suicide in children and adolescents has increased considerably, becoming the second cause of death in this age group. Therefore, the aim of this study was to identify characteristics and factors that could precipitate deaths by suicide in children and adolescents. Methods Using the psychological autopsy method, we studied 28 suicide cases of children and adolescents between 10 and 17 years old. Socio-demographic factors, characteristics of the suicide and family history were documented. Results The proportion of deaths by suicide was the same in females and males (50% each). Most of the suicides were performed at the child/adolescent's home (78.6%) and no history of previous suicide attempts were registered (85.7%). Also, the majority of suicidal individuals came from a dysfunctional family (60.7%). Conclusions Our results identified characteristics of children and adolescents that had died by suicide, such as dying at their homes and coming from dysfunctional families. Knowing the characteristics of children and adolescents that had ended their lives by suicide should be considered in future studies to help developing preventive programs and strategies for treating suicidal behaviors in Mexican children and adolescents.

      The aim of postmortem medicolegal examination in pediatric death is primarily to establish the circumstances and causes of death and to exclude child abuse. In France, pediatric death is systematically documented by medicolegal or medical autopsy. In case of medicolegal autopsy, the complementary examinations, requested and financed by justice, are rarely limited to a histopathological examination. However in medical autopsies other tools are available to the pathologist as toxicology, biochemistry and molecular biology. The purpose of this article is to evaluate the efficacy of forensic histopathology in pediatric forensic autopsies. We analyze the main causes of pediatric death in a forensic context. Between 2004 and 2015, 157 infant deaths were identified in Marseille university hospital. The forensic histopathology and autopsy reports of all 157 cases were available for systematic review. Medical or surgical causes represented 41,3% of deaths in our center, accidental causes 8.1% and child abuse 28,8%. The definitive diagnosis was made at autopsy in 30% of cases and at histopathological examination in 70% highlighting that forensic histopathology is an indispensable tool in pediatric medicolegal autopsies. Significant histological abnormalities may be detected in selected organs such as the brain, lungs, heart, liver, adrenal glands and kidneys in spite of macroscopically normal appearances. This justifies systematic sampling of all organs. Despite the implementation of the French sudden infant death protocol which recommends medical autopsies, too many pediatric autopsies are carried out in a medicolegal context. 30% of the cases remain without diagnosis at the end of the autopsy and histological examination. This number could be reduced by the contribution of others laboratory investigation.

      Cranial suture closure, one of the most commonly used age estimation methods, for decades, however, is often viewed with caution and its reliability is still debated. Few methods of estimating age using the skeleton, especially cranial suture, have been tested on Thais. This study aims to test the traditional aging techniques using cranial suture closure on Thai individuals in order to identify the error rate of each method when applied to a Thai sample. Meindl and Lovejoy (1985), Acsádi and Nemeskéri (1970), and Mann (1991) methods were applied to 175 Thai dry crania. Bias and inaccuracy in the Meindl and Lovejoy, Acsádi and Nemeskéri, and Mann methods resulted in overestimation in young adults and underestimation in older individuals with an inaccuracy range of approximately 13–22 years. The Mann method approached 100% in predicting age in older males, but the method did not fare as well on Thai females. The results confirm inter-population variation does exist. Additionally, differences in age composition between populations used to develop the methods and Thais may lead to an increase in error. This study indicates that these three aging methods should be used in conjunction with other techniques. Further research which develops specific methods for Thais might give better results for age estimation.

      Background Carbon monoxide (CO) poisoning is a common cause of emergency department (ED) visits worldwide with high levels of morbidity and mortality. No inclusive nationally statistics of CO poisoning in Iran is available. The present review aimed to describe and review the pattern of CO poisoning in Iran. Methods The search of Medline, SCOPUS, Cochrane library, Google Scholar, Magiran, IranDoc and SID (Scientific Information Database) yielded only 10 studies discussing the epidemiology of CO poisoning in Iran. Outcomes of interest were determining the demographic characteristics, prevalence and mortality rates, annual trends, main sources and mechanisms, location of incidents of CO poisoning as well as providing the safety awareness and precautions. Results Totally, 10 studies including 6372 victims of CO poisoning were reviewed. The estimated incidence rate of CO poisoning was 38.91 per 100,000, the proportionate mortality rate was 11.6 per 1000 death and the pooled case fatality rate of was 9.5% (95% CI 6.3%–14.30%). Of the total 5105 individuals with CO poisoning, 2048 (40.12%) were male and 3057 (59.88%) were female. In addition, of 5105 poisoned, 4620 (90.50%) were alive and 485 (9.50%) were dead. The number of fatal CO poisoning cases among men and women were 259 (5.07%) and 226 (4.43%) victims, respectively; while the number of non-fatal CO poisoning cases among men and women were 1790 (35.06%) and 2830 (55.44%) individuals, respectively. The mean age of victims was about 30 years. Most of the victims (36.37%) had the educational level of secondary school, marital status of single (52.74%), and occupational status of housekeeper (27.48%). Conclusion The incidence, proportionate mortality and case fatality rates of CO poisoning is high in Iran, particularly in young individuals. It seems that preventive strategies should be taught by health care providers more thoroughly and implemented by policy makers more strictly as a mandatory law.

      National statistics on female homicide could be a useful tool to evaluate the phenomenon and plan adequate strategies to prevent and reduce this crime. The aim of the study is to contribute to the analysis of intentional female homicides in Italy by comparing Italian trends to German and United States trends from 2008 to 2014. This is a population study based on data deriving primarily from national and European statistical institutes, from the U.S. Federal Bureau of Investigation's Uniform Crime Reporting and from the National Center for Health Statistics. Data were analyzed in relation to trends and age by Chi-square test, Student's t-test and linear regression. Results show that female homicides, unlike male homicides, remained stable in the three countries. Regression analysis showed a higher risk for female homicide in all age groups in the U.S. Middle-aged women result at higher risk, and the majority of murdered women are killed by people they know. These results confirm previous findings and suggest the need to focus also in Italy on preventive strategies to reduce those precipitating factors linked to violence and present in the course of a relationship or within the family.

  • Determining when a fracture occurred: Does the method matter' Analysis
           of the similarity of three different methods for estimating time since
           fracture of juvenile long bones

      Radiographic fracture date estimation is a critical component of skeletal trauma analysis in the living. Several timetables have been proposed for how the appearance of radiographic features can be interpreted to provide a likely time frame for fracture occurrence. This study compares three such timetables, by Islam et al. (2000), Malone et al. (2011), and Prosser et al. (2012), in order to determine whether the fracture date ranges produced by using these methods are in agreement with one another. Fracture date ranges were estimated for 112 long bone fractures in 96 children aged 1–17 years, using the three different timetables. The extent of similarity of the intervals was tested by statistically comparing the overlap between the ranges. Results showed that none of the methods were in perfect agreement with one another. Differences seen included the size of the estimated date range for when a fracture occurred, and the specific dates given for both the upper and lower ends of the fracture date range. There was greater similarity between the ranges produced by Malone et al. (2011) and both the other two studies than there was between Islam et al. (2000) and Prosser et al. (2012). The greatest similarity existed between Malone et al. (2011) and Islam et al. (2000). The extent of differences between methods can vary widely, depending on the fracture analysed. Using one timetable gives an average earliest possible fracture date of less than 2 days before another, but the range was extreme, with one method estimating minimum time since fracture as 25 days before another method for a given fracture. In most cases, one method gave maximum time since fracture as a week less than the other two methods, but range was extreme and some estimates were nearly two months different. The variability in fracture date estimates given by these timetables indicates that caution should be exercised when estimating the timing of a juvenile fracture if relying solely on one of the published guides. Future research should be undertaken to compare these methods on a population of known fracture timing, and to better understand the relationship between age of the individual, skeletal health, fracture healing rates, and radiographic characteristics of fracture healing.

      While the physiologic effects of conducted electrical weapons (CEW) have been the subjects of numerous studies over nearly two decades, their effects on neurocognitive functioning, both short-term and long-term, have only recently been studied. In a 2014 study involving use-of-force scenarios, including a CEW scenario, we found that there was a decline in neurocognitive performance immediately post-scenario in all groups; however this effect was transient, of questionable clinical/legal significance, not statistically different between the groups, and, returned to baseline by one hour post-scenario. Two subsequent studies by other authors have also found transient neurocognitive effects in the immediate post-exposure period; however, in one study, the effect was greater in one measure (of 5) for the CEW compared to exertion, and the authors suggested that this effect could have implications for the Miranda waiver obtained before custodial interrogation as well as consent. In our current study, we compared the neurocognitive effects of an exposure to a CEW to another exertion regimen, as well as to alcohol intoxication given the latter has significant established case law with regard to the Miranda waiver and consent. Such a comparison may offer more insight into the clinical/legal significance of any measured changes. As with the prior studies, the neurocognitive performance decrements of the CEW and exertion regimens, found only in one measure in this study (of three), were transient, and here, non-significant. Only alcohol intoxication resulted in statistically significant performance declines across all measures and these were persistent over the study period. Given that the neurocognitive changes associated with the CEW were non-significant, but were significant for alcohol intoxication, and given that current case law does not use intoxication as a per se or bright line barrier to Miranda and consent, our results do not suggest that a CEW exposure should preclude waiving of Miranda rights or obtaining consent.

      Ethanol determination in postmortem blood is one of the most frequently requested analyses in legal medicine and forensic toxicology. Ethyl glucuronide is a non-oxidative ethanol metabolite. It is also a useful marker of ante-mortem alcohol ingestion when ethanol itself has been completely eliminated from the body and could be considered in autopsy cases to obtain more reliable indications. The aim of the present study was to investigate the ethyl glucuronide distribution in postmortem specimens from autopsy cases found to be positive for ethanol. We presented 21 autopsy cases in which central blood, peripheral blood and liver samples were available. Specimens were analyzed for ethyl glucuronide by liquid chromatography tandem mass spectrometry; we also recorded postmortem interval, case history, cause of death, use of drugs, metabolic disorders if present, putrefaction if present, history of ethanol abuse and information about ethanol intake before death. Our aim was to evaluate and to compare the ethyl glucuronide levels in different matrices taken from the same subject in order to provide a better understanding of the interpretation of postmortem ethyl glucuronide concentrations.

      Handprints and dismembered hands are commonly found during crime scene investigations and disaster victim identifications, respectively. It has been indicated that the accuracy of handprint and hand measurements for estimating stature maybe population specific. Since Iban is the largest ethnic population in Sarawak, Malaysia and because the application of anthropometry of hand and handprint within this population as well as other populations within the Southeast Asian countries remain unreported, this present study that investigated the reliability and accuracy of these two anthropometric aspects acquires forensic significance. Upon measuring the height, 21 measurements were recorded on each hand and the corresponding handprint of 50 male and 52 female consented adult Iban subjects. Using univariate statistics as well as simple and multiple regression analyses, interpretation of the measurements examined here was attempted. Results revealed that lengths of hand and handprint are the more reliable traits for estimating stature in both the male and female Iban subjects (p < 0.05) with correlation strength ranging from 0.60 to 0.76. Comparable to the established skeletal standards for hand, the stature prediction accuracy using hand and handprint measurements investigated in this research ranged between 4.29 and 5.78 cm. Hence, this research provided the first forensic standard for estimation of stature among the Iban population in Sarawak that may prove useful for crime scene investigations and disaster victim identifications in Malaysia.

      Aging in custody and the rising population of elderly prisoners are creating compelling challenges for criminal justice, prison and public healthcare systems. Geriatric syndrome and higher prevalence of co-morbidities amongst older inmates result in heightened vulnerability in prison environments. Empirical research addressing older adults' access to medical care in detention is scarce; therefore, this study assessed access to medical care in prison from the perspective of older prisoners in Switzerland. We interviewed a sample of 35 older inmates (average age 61 years) on their experience of healthcare accessibility in prison; data were qualitatively analysed and major themes regarding evaluation of their access to medical services were extracted. Our findings identified three barriers to accessing health services in prison including psychological obstacles, negative consequences of healthcare utilisation, and environmental hurdles. We advocate facilitating older inmates' access to medical care in order to relieve the psychological burden of seeking health services in detention and adequately informing them of their right to demand these services, thereby lessening the negative consequences of their requests. We suggest further training of prison and medical staff for better management of age-related issues in prison can ease the environmental obstacles.

      Head trauma is one of the leading causes of death and disability worldwide. Combined head lesions consist of more than one form of lesions. Biochemical markers of brain injury are used in determining the extent of brain injury and predicting its outcomes.The aim of this study was to investigate the forensic and clinical significance of serum amylase, lipase and gamma glutamyl transferase (GGT) as predictors of the outcome in head injured patients. Patients and methods Sixty head injured patients were enrolled and subjected to personal history taking, general and local physical examination. Glasgow coma scale (GCS), head computed tomography scan and pelvi-abdominal ultrasound were performed. Two blood samples (each 3 mL) were drawn at the time of admission and after 24 h for measuring serum amylase, lipase and GGT levels using special kits. Results Most cases of head trauma occurred accidentally during daytime, in the street as a result of falls and road traffic accidents (RTA). Significant increase of serum amylase, lipase and GGT levels on re-evaluation after 24 h from admission were demonstrated in combined head lesions. There was a high significant negative correlation between GCS and these enzymes both on admission and 24 h after admission. Serum levels of measured enzymes were significantly higher in non-survivors as compared to survivors. Conclusion serum amylase, lipase and GGT are good predictors of the outcome in head injured patients. This could be useful for forensic experts to deduce that the poor outcome of the victims was primarily related to the effects of head trauma and its sequences.

      Recognizing and identifying an individual based on his or her face is a technical and scientific challenge and the objective of our investigation. This article's goal is to establish a method, a foundation and an instrument for carrying out the process of recognizing and identifying an individual. Both the construction of the term and the deepening, conceptualization and epistemology of the process of describing and representing the face through a particular method of recognizing and identifying individuals are described in this article. The proposal of the Prosoporecognographical Chart is an important step in the facial-identification process, establishing taxonomic parameters for the phenotypic manifestations of the elements constituting the face. Based on the proposal presented here, the construction of a protocol for the process of recognizing and identifying an individual can be implemented computationally.

      Introduction The Genital Injury Severity Scale (GISS) is a clinimetrically-tested tool in use for quantifying and qualifying external genital injury after sexual intercourse. Purpose To evaluate inter- and intra-rater agreement of the GISS amongst examiner/raters in an urban, ethnically diverse, emergency department based sexual assault center. Methods The study was conducted in three phases. Six examiners with various years of experience rated their own cases and each others' cases greater than one year after the initial exam. They rated the photographs and documentation of each case at least one year apart. Another six raters utilized a combination of the photos and documentation simultaneously from the same cases. The evaluation method was the completion of the GISS for each phase. Results Based on the experience level of the rater, the differences in overall agreement were not significant. Strength of agreement was highest with the combination of photos and documentation with W ranging from 0.60501 (substantial) to 0.91056 (almost perfect). The GISS variables with the highest level of agreement were tissue break type and toluidine blue uptake type, both with photo evaluation alone and combination of documentation and photos (W = 0.72051 and 0.74599, respectively). Conclusion The Genital Injury Severity Scale is a reliable tool to quantify and qualify the severity of external genital injury when used to evaluate a combination of photos and documentation utilizing midlevel providers trained as sexual assault forensic examiners with various years of experience.

      After an acute sexual assault, children and adolescents often present for medical evaluation and treatment. Physicians have an important role in both the medical and legal components of these cases. Careful physical examination and questioning are important in determining the origin of the trauma. In the presented case report, genital trauma after an acute sexual assault was noted and attributed to the alleged offender's penis piercing. The genital trauma caused by the piercing provided physical evidence linking offender to victim and may have implications for the victim's risk of HIV infection and other blood borne pathogens.

      The history of child abuse pediatrics reflects the development of medicine as a profession influenced by social movements reacting to poverty, economic exploitation, and child maltreatment. As physicians began to specialize in caring for children, egregious cases led them to recognize children were affected by special medical problems and diseases which were compounded by poor conditions and abuse and neglect. They developed the fields of pediatrics and child abuse pediatrics to advocate for their needs in courts and communities. Using a history of prominent physicians and cases, the objectives of this article are to: (1) rediscover the founding of pediatrics in NYC in the context of the environment which served as the setting for its development; (2) highlight our early understanding of the medical issues surrounding child maltreatment, with advocacy and forensic medicine becoming a growing part of medical care for children; and (3) explore the development of child abuse pediatrics in light of prominent physicians making major contributions to child protection. Timelines show the early interplay among social problems, publicized cases, private and governmental agencies, and the development of child abuse pediatrics. The article concludes with potential lessons to be learned and further questions about this interplay of child protection systems and the development of child abuse pediatrics.

      Estimation of age and vitality of burn injury both in the living and dead is essential in forensic practice. Nitric oxide and interleukin-6 (IL-6) play an important role in skin burn healing. In this study, the expression of inducible nitric oxide synthase (iNOS) and IL-6 proteins during skin burn healing in rats was studied for purposes of burn dating and to differentiate between ante-mortem and post-mortem burn. Ante-mortem skin burns were created on forty five rats. Normal and burnt skin samples were taken at 1, 3, 5, 7, 9, 11, 13, 15 and 21 days following burn induction (5 rats for each stage). Post-mortem burn was inflicted 6 h after scarification in another five rats. There was a statistically significant difference in both iNOS and IL-6 expression between the different time intervals of the ante-mortem burn. Expression of both iNOS and IL-6 decreased remarkably in the post-mortem burn with a statistically significant difference from ante-mortem intervals. A statistically significant positive association between the two markers was found. These results indicate that both iNOS and IL-6 expression in ante-mortem burnt skin was time dependent and significantly differed from post-mortem burn. Further research on humans is recommended.

      Background In forensic sciences to determine one's sex is quite important during the identity defining stage. The reliability of sex determination depends on the completeness of the remains and the degree of sexual dimorphism inherent in the population. Computed Tomography is the imaging modality of choice for two- and three-dimensional documentation and analysis of many autopsy findings. Objective The aim of the present work was to assess the reliability of Three-dimensional Multislice Computed Tomography (3D MSCT) to determine sexual dimorphism from certain chest measurements; sternum and fourth rib using the 3D MSCT and to develop equations for sex determination from these bones among adult Egyptians sample. Subjects and methods The present study was performed on 60 adult Egyptians. Their age ranged from 21 up to 74 years and they were equally divided between both sexes. Sixty virtual chests (reconstructed Multislice Computed Tomography 3D images) were examined for detection of Sternal measurements; Manubrium length (ML), Sternal body length (BL), Manubrium width (MW), Sternal body widths(BWa&BWb), Sternal area (SA) [(ML + BL) × (MW + BWa + BWb)/3]and Fourth rib width (FRW). Results All the studied measurements were significantly higher in males than in females. Multiple regression analysis was used to and three significant regression equations were developed for predicting sex using the different studied chest measurements; the sternal measurements, the sternal area and the widths of the right and left fourth ribs with their accuracies 96.67%.95.0%.72.68% respectively. Conclusion Sterunm and fourth rib width revealed significant metric sex differences with the use of Multislice Computed Tomography 3D images thus provide a great advantage in the analysis of skeletal remains and badly decomposed bodies.

      Traumatic (crush) asphyxia is a rare condition caused by severe compression of the chest and trunk leading to often extreme so-called asphyxial signs, including cyanosis in head and neck regions, multiple petechiae, and subconjunctival haemorrhage as well as neurological manifestations. Aims To investigate the neuropathology and brain weight in traumatic asphyxia caused by different accidents such as industrial accidents and road traffic collision. Material and Methods Post mortem records of 20 cases of traumatic asphyxia (TA) resulting from different causes of which four brains are available for comprehensive neuropathological examination. The expected brain weights for given body height and associated 95% confidence range were calculated according to the following formula: baseline brain weight (BBW) + body height x rate (g/cm). The 95% confidence range was calculated by adding and subtracting the standard error (SE) x 1.96 (7–8). Results There was a trend for higher brain weight in the TA cohort but it was not significant (1494 g vs 1404 g, p = 0.1). The upper limits of the brain weight of 95% confidence was 1680 g vs 1660 g, p = 0.9). The neuropathological examination of four available brains from the TA cohort showed severe congestion of blood vessels, perivascular haemorrhages and occasional βAPP deposits consistent with early axonal disruption. Conclusion Brain examination is informative as part of investigation of TA. Developing ischaemic changes and an increase in brain weight are the most likely indicators of a prolonged period of patient's survival.

      Background Age estimation from dental developmental stages is considered comparatively more accurate, reliable and precise than other methods used in forensic sciences. Willems method is the revised version of Demirjian method, based on modified dental maturity scores to estimate age of children in years for both the sexes. Aims To test the applicability and accuracy level of Willems method of dental age estimation in diverse population samples by quantifying the variations between the chronological and estimated ages of an individual. Methodology A systematic search of online databases (Pubmed, Scopus, Embase, Medline, Trip and Web of Science) was performed for identifying the articles utilizing Willems dental maturity scaling method for age estimation in children. All the research articles published in peer-reviewed English language journals between 2001 and January 2017 were included for present systematic review and meta-analysis. Results Out of the total 973 selected articles; thirty one studies were recruited for qualitative analysis and out of them, 15 studies were selected/identified for quantitative and meta-analysis. It was found that Willems method overestimates the age of children to a comparatively lesser extent (−0.04 and −0.02 years) than the Demirjian method (around six months). Conclusion Willems method of dental age estimation gives comparatively lesser overestimations of age than other methods reported in the available literature and is thus, accurate and reliable enough to be utilized for forensic purposes.

      A 4-year-old girl who had been treated for asthma since the age of 2 years had a severe coughing fit and died suddenly. The patient had a history of occasional severe coughing fits, and these fits had been worsening in severity during the week before her death. Prior to death, she was taken to a clinician, and thymic hypertrophy was suspected based on chest X-ray findings. The clinician recommended that she visit a general hospital at a later date; however, she died that night. Postmortem radiology and autopsy revealed a large mass in the anterior mediastinum compressing the heart and airway, and no other findings attributable to sudden death were observed. Therefore, we concluded that the patient's death was attributable to acute respiratory and cardiac circulatory failure secondary to the pressure induced by the mass. Microscopically, the mass showed a cavernous structure composed of cystically dilated, thin-walled large vessels filled with blood. The final diagnosis was a cavernous hemangioma. Hemangiomas are the most common benign vascular anomalies seen in young children; however, mediastinal hemangiomas are rare and can cause life-threatening complications because of their size and location. Therefore, forensic pathologists should include hemangioma as a differential diagnosis in children with anterior mediastinal masses.

      The current study describes the incidence and epidemiological characteristics of eldercide (homicides among victims aged 60 years and older) in Johannesburg for the period 2001 to 2010. A retrospective population-based study was conducted on cases drawn from the National Injury Mortality Surveillance System. A total of 557 eldercides were recorded by NIMSS for the study period with an average annual rate of 23.1 per 100 000. The average annual rate for males was 42.4 per 100 000 and 8.9 per 100 000 for females. There was little variation in the rates by race. Eldercide victims were predominantly male (77.4%), black (48.3%) or white (43.2%), and were mainly killed by firearms (44.8%) or the use of blunt force (27.8%), in a private residence (66.0%), on a week day (53.8%) and during the day (56.1%). The study also found that the characteristics of eldercide varied across males and females, and across black and white race groups. The high incidence of eldercides points to the need for interventions that give special attention to the risk configurations and circumstances associated with these violent deaths.

      Background Case reports of cardiac arrest in temporal proximity to Conducted Electrical Weapon(CEW) exposure raise legitimate concerns about this as a rare possibility. In this pilot study, we respectfully navigate the oversight and regulatory hurdles and demonstrate the intra-shock electrocardiographic effects of an intentional transcardiac CEW discharge using subcutaneous probes placed directly across the precordium of patients with a previously implanted intracardiac EKG sensing lead. Methods Adults scheduled to undergo diagnostic EP studies or replacement of an implanted cardiac device were enrolled. Sterile subcutaneous electrodes were placed at the right sternoclavicular junction and the left lower costal margin at the midclavicular line. A standard police issue TASER Model X26 CEW was attached to the subcutaneous electrodes and a 5 s discharge was delivered. Continuous surface and intracardiac EKG monitoring was performed. Results A total of 157 subjects were reviewed for possible inclusion and 21 were interviewed. Among these, 4 subjects agreed and completed the study protocol. All subjects tolerated the 5 s CEW discharge without clinical complications. There were no significant changes in mean heart rate or blood pressure. Interrogation of the devices after CEW discharge revealed no ventricular pacing, dysrhythmias, damage or interference with the implanted devices. Conclusions In this pilot study, we have successfully navigated the regulatory hurdles and demonstrated the feasibility of performing intracardiac EKG recording during intentional precordial CEW discharges in humans. While no CEW-associated dysrhythmias were noted, the size of this preliminary dataset precludes making conclusions about the risk of such events. Larger studies are warranted and should consider exploring variations of the CEW electrode position in relation to the cardiac silhouette.

      The assessment of sex is of paramount importance in the establishment of the biological profile of a skeletal individual. Femoral relevance for sex estimation is indisputable, particularly when other exceedingly dimorphic skeletal regions are missing. As such, this study intended to generate population-specific osteometric models for the estimation of sex with the femur and to compare the accuracy of the models obtained through classical and machine-learning classifiers. A set of 15 standard femoral measurements was acquired in a training sample (100 females; 100 males) from the Coimbra Identified Skeletal Collection (University of Coimbra, Portugal) and models for sex classification were produced with logistic regression (LR), linear discriminant analysis (LDA), support vector machines (SVM), and reduce error pruning trees (REPTree). Under cross-validation, univariable sectioning points generated with REPTree correctly estimated sex in 60.0–87.5% of cases (systematic error ranging from 0.0 to 37.0%), while multivariable models correctly classified sex in 84.0–92.5% of cases (bias from 0.0 to 7.0%). All models were assessed in a holdout sample (24 females; 34 males) from the 21st Century Identified Skeletal Collection (University of Coimbra, Portugal), with an allocation accuracy ranging from 56.9 to 86.2% (bias from 4.4 to 67.0%) in the univariable models, and from 84.5 to 89.7% (bias from 3.7 to 23.3%) in the multivariable models. This study makes available a detailed description of sexual dimorphism in femoral linear dimensions in two Portuguese identified skeletal samples, emphasizing the relevance of the femur for the estimation of sex in skeletal remains in diverse conditions of completeness and preservation.

      Each individual regardless of sex, age and caste has a particular identification mark present on their body. This study is mainly an attempt to understand the distribution pattern of different types of acquired body marks present on the body which can be used as a marker for individual identification in Forensics. Data was collected by means of observation, interview schedule and interviews from 160 individuals of 6 multi-caste villages of Udaipur in Rajasthan, India. A wide variation was observed in the distribution patterns of various acquired body marks. Scars were the most prevalent (87.5%) followed by body piercing (66%), occupational marks (38.5%), tattoo marks (27.5%) and body deformity (5%). There is a strong association between sex of an individual and presence of tattoo and occupational marks. Type of occupation is associated with the presence of scar and occupational marks. Age also has its influence on the presence and type of - tattoo and occupational marks. This wide variation in the distribution of acquired body marks based on sex, age, educational status, occupation, religion etc. of an individual need to be considered and included as a method of identification of unknown in Forensic Science.

      Background Peripheral nerve injuries (PNI) are relatively common pathologies in clinical practice. PNIs are rare in the lower extremity but have worse prognosis than those in the upper extremity. Electrodiagnostic studies could help better understanding PNIs. In this study, we aimed to evaluate the distribution of lower extremity PNI in traumatic patients in northwest of Iran. Methods In this prospective study, 74 patients (62 male and 12 female with mean age of 38.39 ± 14.42 years) with possible lower or lumbosacral peripheral nerve injury were studied. Patients' demographic information and physical examination findings were recorded. Electrodiagnostic investigations including electromyography and Nerve Conduction Study were performed for all subjects. Results Common chief complaints were pain and weakness. Impairment in the sensory function was present in 59.5% and muscle force reduction in 47.3%. PNIs were present in 23.0% and mostly were severe. Injuries in sciatic nerve were the most common PNIs (16.2%). Electrodiagnostic studies showed radiculopathy in 48.7% and plexopathy in 8.10% of cases. In 52 patients (70.3%), the physical examination findings were compatible with Electrodiagnostic studies. Conclusion Not all patients presenting with traumatic injuries have lower extremity PNIs. Due to the nature of the trauma and the anatomical course of the nerves, sciatic nerve is more susceptible to traumatic injuries.

      The GlobalFiler™ (Life Technologies), Investigator® 24plex QS (Qiagen), and PowerPlex® Fusion 6C (Promega) kits are the latest generation 6-dye fluorescent chemistry STR-PCR amplification kits. These kits allow for the simultaneous amplification of the CODIS core loci and the European Standard Set loci, as well as a few Y-STR loci in addition to the standard sex-determining marker Amelogenin. The present study was designed to be a preliminary evaluation of the three STR-PCR kits in terms of sensitivity, profile recovery from degraded DNA samples, tolerance to PCR inhibitors, and detection of minor components in DNA mixtures. The results showed that the three STR-PCR kits had relatively similar performance with each kit faring better for the different aspects studied. The PowerPlex® Fusion 6C and the Investigator® 24plex QS kits were shown to tolerate inhibitors better, while the GlobalFiler™ kit appeared to have a higher mean percentage recovery of alleles from low template DNA samples and for minor components in DNA mixtures.
