This study investigates the pattern of hand injuries presenting to a UK regional tertiary centre. All referrals to our Hand Surgery Unit in 2019 were reviewed. Subgroup analyses of sex, deprivation, occupational injuries and assault cases were carried out. Over the study period, 4216 cases were referred. Most were male (70%), with a median age of 36 years and from a deprived area (75.2%). Soft tissue injury was documented in 53.6% and bone injury (fracture/dislocation) in 52.4%. Surgical management was required in 2214 (52.5%) cases. Work-related injuries accounted for 16.7% of cases and were more likely to require surgery. Assault-related injuries accounted for 8% of cases, with a male preponderance. Our findings can help facilitate service provision and guide regional and national prevention policies.Level of evidence: III.

BACKGROUND: Workplace violence (WPV) against health-care professionals has been a concern worldwide as it strains the relationship between the patient and healthcare professionals. Implementing mitigation interventions to help the healthcare professionals to prevent and manage these violent episodes might make the workplaces more secure.
OBJECTIVE: This study aimed to synthesize the recent evidence on intervention strategies for workplace violence.
METHODS: Four electronic databases (PubMed, Wiley, Cochrane and Google Scholar) were searched for peer-reviewed intervention studies published in the last 11 years to mitigate workplace violence. A qualitative synthesis of the findings from included studies was done.
RESULTS: A total of 17 studies were identified based on prevention and management of workplace violence. The interventions were mainly educational in nature based on a workshop format. These interventions were found to be effective in improving the perceived ability to deal with situations that lead to violence.
CONCLUSIONS: Strategies to mitigate violent episodes could be helpful to health-care professionals and administrators in their attempts to make safer workplaces in the health-care settings.

BACKGROUND: Community assault is an interpersonal violence frequently seen in the emergency centres around South Africa. Its aim is to inflict serious injuries to a suspected perpetrator. Data has not been published in Mamelodi Regional Hospital setting whereas the cases have been observed in the emergency centre (EC). The study objectives were to determine the incidence and factors associated with being a victim of community assault in the EC in a regional hospital in Pretoria and clinical outcomes.
METHODS: We retrospectively reviewed the medical records of adult patients who were treated for assault in the EC of Mamelodi Regional Hospital between 5 March 2017 and 5 March 2018. EC electronic registries and medical file were used to identify all patients who presented with body injuries due to assault.
RESULTS: Only 807 of 1070 medical records had complete data on the exposure variables of study interest. Of the 807 participants who presented with body injury due to assault, 77 (9.544% (95% CI 7.52 to 11.57)) were due to community assault. The majority of the victims were young adults, of male gender and not married. More than half of the participants were unemployed. Young adult age doubled the odds of being a victim of community assault odds ratio (OR) 2.19 (95% CI 1.02 to 4.70). The odds of being a victim of community assault for males were 11 times the odds of females OR 11.30 (95% CI 2.74 to 46.49). Of the 77 victims of community assault, 45 (58%) were admitted, 25 (32%) were discharged after receiving treatment, 6 (8%) refused treatment and 1 (1%) died.
CONCLUSIONS: We describe the incidence of, and factors associated with, community assault in the EC of Mamelodi Regional Hospital in Pretoria. Our findings suggest that a modest incidence rate of being a victim of community assault. Young adult males are mostly the target victims of community and non-community assault. Further research is needed to understanding factors precipitating community assault and to test potential community and non-community assault prevention interventions, targeting young adult males.

When staff experience responsive behaviors from residents, this can lead to decreased quality of work life and lower quality of care in long-term care homes. We synthesized research on factors associated with resident responsive behaviors directed toward care staff and characteristics of interventions to reduce the behaviors.
We conducted a mixed-methods systematic review with quantitative and qualitative research. We searched 12 bibliographic databases and \"gray\" literature, using 2 keywords (long-term care, responsive behaviors) and their synonyms. Pairs of reviewers independently completed screening, data extraction, and risk of bias assessment. We developed a coding scheme using the ecological model as an organizing structure and prepared narrative summaries for each factor.
From 86 included studies (57 quantitative, 28 qualitative, 1 mixed methods), multiple factors emerged, such as staff training background (individual level), staff approaches to care (interpersonal level), leadership and staffing resources (institutional level), and racism and patriarchy (societal level). Quantitative and qualitative results each provided key insights, such as qualitative results pertaining to leadership responses to reports of behaviors, and quantitative findings on the impact of staff approaches to care on behaviors. Effects of interventions (n = 14) to reduce the behaviors were inconclusive.
We identified the need for an enhanced understanding of the interrelationships among factors associated with resident responsive behaviors toward staff and processes leading to the behaviors. To address these gaps and to inform theory-based effective interventions for preventing or mitigating responsive behaviors, we suggest intervention studies with systematic process evaluations.

From 85348 inmates in England and Wales, over 26,000 incidents of assault and 40,000 of self-harm were reported from within prisons in 2016. This study focuses primarily on burn injuries in prison, determining the predominant aetiology as well as clinical outcomes of these injuries.
Data was retrieved retrospectively and a case series performed, including all burns referred from regional prisons to our centre from 2007 to 2017 and comprising patient demographics, mechanism of injury, total body surface area affected, management, and outcome. Cost analysis of care was conducted using a previously published framework.
18 cases from three regional prisons were recorded, with 67% from a single prison. Referrals rose exponentially over time, with 44% occurring in 2017. 94% were scald burns, and 56% secondary to assault, primarily through the use of kettles and mostly targeting the face and trunk. The mean TBSA of burn was 2.89% (<1-8%), and 80% received first aid. 72.2% were admitted to hospital for an average of 4 days. All burns were managed nonoperatively with dressings and underwent on average 2 outpatient reviews (1-8).
The disproportionate spread of referrals across the prisons correlates partly with the respective populations, but may also represent contrasting medical provisions. The recurring method of assault reflects the relative ease of access to hot water as a harmful agent, predominantly presenting with scalds affecting more critical areas, and with concurrent physical trauma in nearly half of cases which presents management challenges.
Targeted education is recommended to reduce the incidence and ensure adequate management of burns in prison, referrals for which are demonstrably rising. Accordingly, the Burns Outreach team can provide training to in-house prison health staff and review referrals to specialist Burns services, aiming to ensure equitable care while alleviating costs associated with transfer to and management in hospital.

UNASSIGNED: Jael\'s syndrome, an intentional injury caused by a knife in the face or skull is a rare encounter in clinical and forensic practice, rarely involving an impacted knife. Clinical and radiographic diagnosis is essential to identify severity of injury and location of the retained knife. To the best of our knowledge, this is the first reported novel case of Jael\'s syndrome in Tanzania.
METHODS: We present the case of a 31-year old man admitted at Muhimbili National Hospital following an impacted knife. The stab wound extended to the medial wall of left orbit and ended just before the optic foramen associated with vitreous hemorrhage and the retained knife caused superoposterior displacement of the globe. Multidisciplinary management was instituted including prompt evaluation, imaging and surgical removal of the knife under general anesthesia.
UNASSIGNED: Plain skull X-ray revealed an extensive retained blade and computerized tomography (CT) showed the tip of the blade adjacent to the right styloid process with no neurovascular compromise. Initial concern was the left eye that was reported to be viable by ophthalmologists. Incredibly, the patient had no initial sequelae from such an extensive injury and had unremarkable recovery with no complications apart from the wound to left inferior rectus muscle that was conservatively managed. Simple withdrawal of the retained knife was successful.
CONCLUSIONS: Craniofacial retained knives are rare. Thorough prompt initial evaluation and intervention is vital since improper management can be devastating.

WHAT IS KNOWN ON THE SUBJECT?: Trauma among psychiatric nurses and other healthcare workers is related to workplace violence, but other risk factors may also contribute, including those occurring before, during or after workplace violence. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: Most previously identified PTSD risk factors were not tested or supported in research with psychiatric nurses, although there is promising evidence for risk factors including severe or injurious assault, cumulative exposure, burnout, and other worker characteristics. We identify directions for research needed to improve knowledge, including collecting data before nurses experience workplace violence, defining workplace risk factors consistently and conducting and reporting qualitative analysis. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Provide training in risk assessment and violence prevention to psychiatric nurses. Offer mental health support to those exposed to violence, especially with cumulative exposure. ABSTRACT: Introduction Psychiatric nurses are at risk of workplace violence and post-traumatic stress disorder (PTSD). There is limited understanding of pre-trauma and post-trauma risk factors. Aim Our aim was to review factors associated with workplace PTSD in psychiatric nurses. Method We searched quantitative and qualitative studies from 1980 to 2019 in 23 databases plus abstracts for studies on psychiatric hospital nursing staff, potentially traumatic workplace events, workplace factors and PTSD. Following duplicate abstract (n = 10,064) and full-text (n = 199) screening, data were extracted in duplicate from 19 studies. Using best-fit framework synthesis, we identified workplace violence, pre-trauma and post-trauma risk factors. Results Six variables yielded evidence in at least two empirical studies scoring at least 6/8 on a quality measure, or one such study plus more than one other study (\"promising\": severe/injurious assault, cumulative exposure, burnout, poor mental health, low compassion satisfaction, neuroticism). Four were supported by at least one better quality study or at least two others (\"suggestive\": gender, poor training, any physical aggression exposure, compassion fatigue). Discussion Pre-trauma measures, consistent definitions of workplace exposures and thorough reporting of quantitative results are needed to improve research. Implications for Practice Violence prevention and mental health care for exposed nurses appear the most promising targets for PTSD prevention. Therefore, it is particularly important to understand workplace violence and mental health among nurses working in psychiatric hospitals.

Ocular surface chemical injury (OSCI) is a common type of ocular emergency that can potentially cause significant and permanent visual impairment. However, the global prevalence, demographic factors, socioeconomic burden, and psychological impact of OSCI have not been well investigated or reported. This review aims to provide a comprehensive overview of these aspects, highlight gaps in the literature, and advocate key strategies in reducing the incidence of OSCI. OSCI was responsible for 0.1-15% of all ocular emergency presentations, with an estimated incidence of 5.1-50 per 100,000 population-year. Young working adult men were the most at-risk group, though high rates of OSCI were also observed in young children in developed countries, especially from detergent pods. Low- and middle-income countries were noted to have higher proportions of assault-related and pediatric OSCI cases, often with more severe presentations. Direct and indirect costs for some hospitalized patients led to loss of all personal and household income after the injury. Emergency department costs in the United States were estimated at $106.7 million over four years and costs of treating long term complications such as glaucoma were estimated to be as high as $93,003 over five years. Significant negative impacts on visual and health-related quality of life and psychological well-being have been reported after injury, with higher rates of anxiety, depression, and psychological distress compared to the general population.

BACKGROUND: Ocular trauma is a common occurrence in trauma settings but often occurs with little to no effect on the vision of the patient. Traumatic enucleation is a rare but devastating injury.
METHODS: A 40-year-old male presented to our trauma center after an assault resulting in right globe enucleation. CT confirmed absence of the globe with disruption of the ipsilateral orbital contents and distal optic nerve disruption. The patient was started on intravenous antibiotics and the right orbit was packed. He was taken to the operating room for exploration of the right orbit and placement of an implant. His remaining hospital course was unremarkable.
CONCLUSIONS: Documented mechanisms of injury for traumatic enucleation are diverse, but often involve significant retro-ocular force to completely dislodge the globe from the orbit. Optic nerve avulsion may cause associated optic nerve chiasm damage leading to temporal hemianopia in the uninjured contralateral eye. Treatment involves stabilization and preparation for future implant placement.
CONCLUSIONS: Traumatic enucleation is extremely rare. Development of a grading system applicable to traumatic enucleation may be helpful in guiding management in this complex patient population.

The development of the law of consent has led to much discussion within the dental literature as to how these changes might impact practice. The move from a practitioner-focused standard of consent to a patient-focused standard has altered the nature of the framework required to support a patient\'s decision-making to avoid an allegation or finding of a negligent consent process. Contrastingly, there has been little in the way of exploration as to how the law of battery (in civil matters) and assault (in criminal cases), where consent is entirely absent, might apply to dentistry and the practice of the profession. This article considers the law of consent, using several key examples from dentistry, as well as providing an update of recent case law of relevance to dental practice.
