Background

Fractures are an important symptom of physical violence that will negatively affect the woman's quality of life in the coming years. However, there is limited information in the literature about fractures in women exposed to domestic violence (DV). The aim of this study was to compare fracture development rates and age distributions in women exposed to DV and intimate partner violence (IPV), a component of DV, and women exposed to other physical violence (OV), to determine the incidence of DV cases with and without fractures, and to determine fracture locations in DV cases and to identify diagnostic lesions accompanying fractures.

Methods

A retrospective review was made of patients injured as a result of IPV, other domestic violence (ODV) and OV. The data of cases with fracture were analyzed in terms of age groups of the victims and according to location and types of fractures.

Results

Of the 854 female patients aged >18 years who were admitted to the hospital due to violence, 55.2% were exposed to DV. Most DV victims (87.9%) were assaulted by intimate partners. The incidence of fractures in IPV cases (7.2%), was nearly twice that of ODV and OV cases. The mean age of IPV cases with fractures (42.1 ± 12.1 years) was significantly higher than that of IPV cases without fractures (33.1 ± 11.8 years) (p < 0.05). Most IPV cases (61.8%) were aged <35 years. Most DV cases with fractures (75%) were aged <50 years. Facial/neck injuries (41.5%) and facial fractures (52.6%) were prominent in DV cases.

Conclusion

The results of this study of the presence of facial fractures, especially in women aged <50 years, is an important finding that can alert doctors to potential cases of domestic violence.

Liposuction is a surgical procedure performed worldwide. Although many fatal complications of liposuction have been reported, to our knowledge, no cases of fatal liposuction complications specifically related to the face region have been reported. Here, we present a case of a woman in her 30s who developed a cervical hematoma and upper airway obstruction following facial liposuction. We present this unique case to highlight the rare occurrence of fatal complications specific to facial liposuction.

The patient underwent liposuction during surgery at a cosmetic surgical clinic and awoke from anesthesia after the procedure. Two hours later, she developed a neck swelling and dyspnea. While the anesthesiologist managed her airway, she went into cardiopulmonary arrest. She was then transferred to the emergency room but died on day 7 of hospitalization. The autopsy revealed swelling of the right cheek and mandible, a subcutaneous hematoma in the same area, and laryngeal edema. A damaged facial artery branch was identified, which was consistent with the computed tomography (CT) findings on admission. CT also showed that the hematoma compressed the right internal jugular vein, suggesting that venous outflow impairment caused by the hematoma may have exacerbated the airway obstruction.

This case reveals that cervical hematoma caused by facial liposuction can cause fatal upper airway obstruction and the onset of the hematoma may be gradual.

Peer review of medical opinions provided in cases of suspected child physical abuse is generally considered to be best practice for pediatricians engaged in this field. However, there are no published standardized guidelines on how pediatricians should undertake physical abuse peer review including case selection and process. Due to the high-stakes nature in the field of child abuse pediatrics, rigorous quality assurance practices and oversight mechanisms are essential to safeguard children, families, health care providers, and intersecting systems. The Suspected Child Abuse and Neglect program at The Hospital for Sick Children, Toronto, Canada developed a structured peer review process for cases of suspected physical abuse. Included in the process is an approach for the evaluation of institutional complaints received related to a child abuse pediatrician's medical opinion. This quality assurance process is presented so that other child abuse pediatricians and programs may replicate or adapt the protocol for their own local context.

Penetrating head injury to accomplish suicide by a non-ammunition-related projectile discharged from a nail-gun is a very rare entity. The authors describe even much rarer, and the first reported case of a suicide penetrating head injury by a construction nail discharged from a blank cartridge of a pistol. The absence of beveling and muzzle impression, the non-ejection of the discharged cartridge, and the exit of just the tip of the nail from the other side of wound were the atypical features in this firearm fatality sustained at a contact-range. The entry wound prototypes like abrasion and grease collar, and blackening were absent. An improvisation to insert a construction nail into the chamber of firearm, for utilization as a projectile was another unique highlight here. The deceased was a construction builder. Being debt-ridden, he probably could not manage to purchase even one live cartridge for his licensee pistol to bring suicidal ideation to culmination.

Professionals in the justice system are particularly susceptible to occupational stress and burnout due to factors intrinsic to their profession. The Forensic Professional's Stress Inventory (FPSI) was designed to assess stress and psychological distress specifically in justice system professionals. A preliminary 41-item scale was administered to a sample of 690 forensic professionals (i.e., judges, lawyers, and attorneys). Exploratory factor analysis, exploratory structural equation modeling, and confirmatory factor analysis were conducted to find the most interpretable and parsimonious factor solution for FPSI. The 25-item bifactor model (with four first-order factors) demonstrated the most adequate fit to the data. Overall, FPSI revealed adequate psychometric properties and would be a useful instrument for assessing psychological strain and stress in forensic professionals.

Since 2019, the number of children apprehended by the United States Custom and Border Patrol at the southern border continues to increase. Many of these children are fleeing violence and extreme poverty and qualify for several forms of humanitarian relief. Trained pediatric health professionals have an essential role to play in documenting evidence to support their petitions. The goal of a forensic medical and psychological evaluation is to establish the facts related to the reported incident(s), provide forensic evidence to support these claims, and provide an expert opinion on the degree to which a finding correlates with the client's reports through a written affidavit. Research studies have demonstrated a significant increase in asylum grant rate for cases that include an evaluation. As demand for forensic evaluations has grown, multiple clinic models have emerged, including volunteer networks, student-led clinics, and faculty-led clinics. The Forensic Assessment for Immigration Relief (FAIR) Clinic offers a sustainable infrastructure while emphasizing the training of pediatric healthcare professionals on the conduct of trauma-informed, culturally attuned, and developmentally appropriate forensic evaluations. This paper outlines the year-long process of developing and launching a clinic specializing in pediatric forensic medical and psychological evaluations as a blueprint for replication.

Objective

A comparison between Cinematic Rendering Technique (CRT) and Volume Rendering Technique (VRT) in cases with postmortem CT-angiography (PMCTA) was carried out.

Methods

For different injuries seen in PMCTA, a VRT and a CRT image of exactly the same pathological section was generated. Two questionnaires were created, one with CRT and one with VRT reconstructions, with the same questions per 3D-image. The questionnaires were sent to forensic pathologists, lawyers and police officers. In total eleven different injuries had to be analyzed.

Results

In total 109 questionnaires were answered fully. Of these returnees, 36 stated that they were forensic pathologists. Seventy-three people were assigned to the group of medical laypersons, in the study this group consists mainly of police officers, judges and lawyers. Between the two software programs CRT and VRT that were compared, no significant difference could be identified in any of the participating groups with regard to the assessment of the life-threatening nature of the injury images shown. When asked about the comprehensibility of pathology, there was a significant difference in favour of CRT. This advantage was apparent to named medical laypersons and to forensic pathologists.

Conclusions

The study showed a positive trend that CRT may be more understandable than VRT. Not only the medical laypersons, but also the forensic physicians found CRT to be beneficial.

In the United States, the governance of unnatural death certification varies greatly by state. Although cross-sectional research has linked mortality data quality with variation in medicolegal death investigation systems across states-especially with regards to drug-related deaths-this relationship has not be sufficiently tested using longitudinal data. This research assesses the impact of system governance reform on the quality of drug mortality data by assessing the impact of transitioning from a coroner system to a medical examiner system on data quality. The research finds no evidence that system-level reform is associated with improved drug-related mortality data quality. These findings suggest that alternative methods should be examined for improving public health data concerning drug-related mortality. These likely include focusing on individual-level characteristics and practices of officials and offices, rather than system-level variables.

Background

Sexual assault (SA) poses a threat to all areas of contemporary society. Although older individuals represent a vulnerable demographic, a considerable gap exists in the literature regarding the context in which older individuals experience SA. This study aims to provide a comprehensive description of older individuals' attendances at the Sexual Assault Treatment Unit (SATU) network in the Republic of Ireland.

Methods

A 7-year national cross-sectional study was performed to analyse the attendances of older people (≥65 years old) to the SATU network, and to compare them with younger attendances (<65 years old), with a more in-depth subset analysis of Dublin SATU attendances.

Results

During the study period, there were 6478 attendances to the SATU network, of which 0.93 % (n = 60) were older people. These included 59 females and 1 male, with the average age of 76.05 years ± 8.16. Forensic examinations were performed in 81.7 %, with the majority seeking assistance within 7 days (80 %). Comparison of older (≥65 years) and younger (<65 years) attendees revealed older individuals were more uncertain whether a sexual assault had occurred (35.5 % vs. 14.4 %, p < 0.001) but more likely to report the incident to the police (78.3 % vs. 64.3 %, p = 0.02). Assault by a person in authority was significantly more common in older age groups (11.7 % vs. 1.8 %, p < 0.001). Older individuals were significantly more likely to be assaulted in their own home (33.3 % vs. 21.5 p < 0.03) or in ‘other-indoors' settings (e.g. nursing home/hospital) (43.3 % vs. 23.4 % p < 0.001). They were less likely to be assaulted in the assailant's home (5.0 % vs. 22.9 %, p < 0.001) or outdoors (5.0 % vs. 19.7 %, p = 0.004).

In our subset analysis of 19 cases, 73.7 % occurred in healthcare facilities, 63.2 % had dementia, and 42.1 % were care dependent. Genital injuries were present in 44.4 % of patients and extra-genital injuries in 22.2 %.

Conclusion

Unique patterns are evident in sexual assault experienced by older people, underscoring the necessity for tailored interventions and effective support systems for reporting and addressing this vulnerable demographic. This is especially crucial in healthcare environments, where a notable proportion of cases occur, frequently involving individuals with dementia and requiring care assistance.

The pattern of neck injuries sustained in fatal cases of external compression to the neck is recorded during Post Mortem Examinations (PME), to assist in the interpretation of the circumstances that led to death. In this study, the PMEs performed for 298 cases of hanging and strangulation occurring between 2016 and 2020 in Ireland were retrospectively reviewed for the purpose of recording and collating the external and internal neck injuries observed during each PME, as well as the toxicology results for each decedent. Statistical analysis was performed to investigate potential novel associations between anthropometric variables pertaining to the decedents and the PME findings in cases of hanging and strangulation, serving to add further data to the existing body of research in this area and to assist in the resolution of future cases of hanging or strangulation where there are conflicting findings. In completing statistical analysis, it was found that there was no discernible association between the occurrences of cartilaginous neck fractures (CNFs) with increasing ligature width. Positive associations between increasing weight and BMI of the decedents were identified, and a significantly positive association between the increasing height of the decedent and the incidence of CNFs were identified. Analysis of the toxicology demonstrated that antipsychotics were implicated most frequently in cases of incomplete and complete hanging associated with CNFs and that opioids were implicated most frequently in cases of manual and ligature strangulation associated with CNFs.

Objective

To record the pattern of neck injuries sustained in retrospective cases of hanging and manual/ligature strangulation and to collate these findings so as to provide scientific evidence to support the interpretation of the findings in future cases of suicidal hanging and homicidal manual/ligature strangulation for the purpose of medicolegal investigation. To analyse the associations between the occurrence of neck fractures and anthropometric variables pertaining to the victims in cases of complete hanging.

Study design

The reports of 298 Post Mortem Examinations (PMEs) performed for cases of hanging and manual/homicidal ligature strangulation between 2016 and 2020 in Ireland were retrospectively reviewed. Pseudoanonymised data sets were recorded for each report, which included the following parameters: neck injuries (soft tissue and cartilaginous), weight, height, BMI and ligature width, toxicology, noose position, ligature material, tongue protrusion, sex and age. Permission for the use of this data was sought from the pathologists and coroners involved in these cases. The data was analysed according to descriptive statistical methods and logistic regression analysis.

Results

Logistic regression analysis was undertaken to examine the associations between unit increases in ligature width and inc
