The eye in forensic practice: In the living.

Eye examination plays an important role when living individuals are forensically investigated. The iris colour, retinal scans and other biometric features may be used for identification purposes while visual impairments may have legal implications in employment, driving and accidents. Ocular manifestations provide clues regarding substance abuse, poisoning and toxicity, and evidence of trauma, abuse or disease can be revealed along with psychological traits and lifestyle. Thus, the eye is a valuable tool in forensic investigations of living subjects, providing identifying characteristics along with health information. This review focuses on the medico-legal aspects of the eye's contribution when the living are subjected to forensic examination.

Striving toward safe abortion services in Nepal: A review of barriers and facilitators.

Background and Aims: Despite the decriminalization of abortion in Nepal in 2002, unsafe abortion is still a significant contributor to maternal morbidity and mortality. Nepal has witnessed a significant drop in abortion-related severe complications and maternal deaths owing to the legalization of abortion laws, lowered financial costs, and wider accessibility of safe abortion services (SAS). However, various factors such as sociocultural beliefs, financial constraints, geographical difficulties, and stigma act as barriers to the liberal accessibility of SAS. This review aimed to determine key barriers obstructing women's access to lawful, safe abortion care and identify facilitators that have improved access to and quality of abortion services. Methods: A systematic search strategy utilizing the databases PubMed, CINAHL, Scopus, and Embase was used to include studies on the accessibility and safety of abortion services in Nepal. Data were extracted from included studies through close reading. Barriers and facilitators were then categorized into various themes and analyzed. Results: Of 223 studies, 112 were duplicates, 73 did not meet the inclusion criteria, and 18 did not align with the research question; thus, 20 studies were included in the review. Various barriers to SAS in Nepal were categorized as economic, geographic, societal, legal/policy, socio-cultural, health systems, and other factors. Facilitators improving access were categorized as economic/geographic/societal, legal/policy, socio-cultural, and health systems factors. The patterns and trends of barriers and facilitators were analyzed, grouping them under legal/policy, socio-cultural, geographic/accessibility, and health systems factors. Conclusion: The review identifies financial constraints, unfavorable geography, lack of infrastructure, and social stigmatization as major barriers to SAS. Economics and geography, legalization, improved access, reduced cost and active involvement of auxiliary nurse-midwives and community health volunteers are key facilitators.

Differentiating suicide from homicide in sharp-force fatalities with stab and/or incised wounds: A scoping review.

The majority of sharp-force fatalities with stab and/or incised wounds are homicides. However, suicidal sharp-force fatalities with stab and/or incised wounds are also reported. Thus, distinguishing suicidal stab and/or incised wounds from homicidal stab and/or incised wounds is significant from the forensic perspective. This scoping review primarily summarizes the existing research findings on the differentiation of suicide from homicide in sharp-force fatalities with stab and/or incised wounds. The literature was systematically searched on February 28, 2023, using the PubMed database. A search string formed by a combination of keywords related to suicide, homicide, and stab and incised wounds yielded 23 records. After applying the eligibility criteria, six records/studies met the inclusion criteria and were included in the present scoping review. Results showed that the predictive strength of various parameters, either individually or collectively, in diagnosing the manner of sharp-force fatality as suicide or homicide is not always hundred percent accurate. Some of the important predictors of the homicidal manner of death in sharp-force fatalities include clothing damage, presence of defense injuries, presence of injuries caused by another type of violence other than sharp-force, vertically oriented chest stabs, and sharp-force injuries in the head and back anatomical sites. Some of the important predictors of the suicidal manner of death in sharp-force fatalities include the presence of tentative injuries, sharp-force injuries to the wrist, and the presence of a suicide note.

Systematic review of laryngohyoid fractures in fatal falls: A potential mimicker of strangulation.

Fractures of the laryngohyoid complex are classically associated with deaths due to strangulation. Recent studies, however, indicate the possible presence of such fractures in fatal falls. The primary focus of this systematic review is to analyze the characteristics of laryngohyoid fractures in the context of falls to aid in a more accurate interpretation of autopsy findings. Search for relevant literature occurred on PubMed on the 26th of October 2022, and Embase and Web of Science on the 5th of November 2022. Inclusion criteria included being a primary study, published in English, involving fatal falls and injuries to the laryngohyoid complex, and presenting sufficient details about the relevant cases. Four case reports and six descriptive retrospective studies were included in the final analysis yielding a sum of 38 cases. The risk of bias was assessed using the Joanna Briggs Institute (JBI) critical appraisal tools. Potential limitations of this study include the inclusion of case reports and studies published in English only. The cumulative male-to-female ratio was 23:15 with a mean age of 48 years old. The fall height ranged from standing height to 60 m. Forty-three fractures to the laryngohyoid complex were identified with the thyroid cartilage most commonly affected, followed by fracture of the hyoid bone, and finally the cricoid cartilage. While cases of falls did indeed display hallmark laryngohyoid findings classically displayed in strangulation, they also featured unique presentations such as fractures of the clavicle and a reduced prevalence of conjunctival petechiae.

School violence in Saudi Arabia: A scoping review.

School violence comprises a broad spectrum of physical, psychological, and sexual acts that impact children and adolescents physically, psychologically, and academically. The aim of this article is to provide a scoping review of school violence in Saudi Arabia. The adversities of school violence and related forensic, legal, and social aspects from a Saudi Arabian perspective are discussed. The articles were extracted through the Medline, Embase, and Web of Science databases in a comprehensive criteria-based search strategy using relevant MeSH terms to identify papers related to school violence in Saudi Arabia from inception to October 6, 2022, and a total of 14 studies have been extracted and discussed. There were indicates that male students tend to engage in physical violence while females tend to engage in verbal violence. The consequences included having a significant impact on students' mental wellbeing, followed by a decrease in academic performance. Therefore, this study will identify the risk factors and present the preventive methods that can guide local institutions to establish new policies to increase awareness and implement culturally acceptable, community-based programs against school violence in Saudi Arabia.

Human sacrifice: From religious ritual to legal sentence in Nepal.

Human sacrifice is a gruesome and controversial practice where one or more individuals are killed as part of a religious ceremony or as a gift to a deity. While the practice has been widely condemned globally, it still persists in some communities in some countries. Nepal, in particular, has a history of animal sacrifice with larger offerings taking place every five years. While animal sacrifice is legal, the ultimate punishment for engaging in human sacrifice is a legal sentence. This article examines the historical and cultural context of sacrifice in Nepal and explores some contemporary cases of human sacrifice reported in the media. The article also considers the impact of superstitious beliefs and the need for evidence-based attitudes to support human rights.

Suicidal Ideation Among Medical and Nursing Students.

BACKGROUND: Suicidal ideation is a major predictor of suicide attempts. The present study was conducted to compare the prevalence of suicidal ideation and its risk factors among medical and nursing students in Nepal. METHODS: An online survey was carried out among a cohort of medical and nursing students of Lumbini Medical College using questions derived from General Health Questionnaire-28 and Patient Health Questionnaire-9. RESULTS: 153 medical and 148 nursing students participated in the study. Lifetime suicidal ideation was present in 20.6%(n=62) medical and 13.95%(n=42) nursing students. Suicidal ideation in the last one year was present in 48 medical and 36 nursing students. There were higher odds of suicidal ideation in medical students who had parental neglect, psychiatric disorder, physical and sexual abuse, substance abuse, and academic performance dissatisfaction (p<0.05), whereas the odds were higher in nursing students with psychiatric disorder, parental demands, alcohol consumption, and academic performance dissatisfaction but was not statistically significant. Thematic analysis of the responses for open-ended question for reasons for previous suicide plans or attempts among four medical and eight nursing students revealed relationship issues, history of adverse childhood experiences, academics-related circumstances, and other individual problems as suicide antecedents. CONCLUSIONS: Periodic motivational speeches and counselling sessions during all the semesters of professional schooling would help decrease suicidal ideation. Mental health awareness programs for medical and nursing students should be aimed at reducing mental illness-associated stigma and promoting timely professional help-seeking behavior.

Cerebrovascular disease in COVID-19: a systematic review and meta-analysis.

Background: The association between COVID-19 and acute cerebrovascular disease (CVD) has not been explored extensively. New data has come to light which may change previous results. Methods: We queried the PubMed electronic database from its inception until February 2022 for studies evaluating the incidence of stroke in COVID-19 patients. Results of the analysis were pooled using a random-effects model and presented as odds ratios (ORs) with 95% confidence intervals (95% CIs). Results: 37 studies consisting of 294,249 patients were included in our analysis. Pooled results show that the incidence of acute CVD events in COVID-19 positive patients is 2.6% (95% CI: 2.0-3.3; P<0.001). Cardioembolic (OR=14.15, 95% CI: 11.01 to 18.19, P<0.00001) and cryptogenic (OR=2.87, 95% CI: 1.91 to 4.32, P<0.00001) etiologies were associated with COVID-19 positivity. Risk factors for CVD events in patients with COVID-19 were atrial fibrillation (OR=2.60, 95% CI: 1.15 to 5.87, P=0.02), coronary artery disease (OR=2.24, 95% CI: 1.38 to 3.61, P=0.0010), diabetes (OR=2.46, 95% CI: 1.36 to 4.44, P=0.003) and hypertension (OR=3.65, 95% CI: 1.69 to 7.90, P=0.005). Conclusion: COVID-19 infection is associated with an increased risk for acute CVD and is associated with cardioembolic and cryptogenic etiologies and the risk factors of atrial fibrillation, coronary artery disease, diabetes and hypertension in COVID-19 positive patients.

The medico-legal death investigation system in Nepal.

In Nepal, police inquests have several limitations. When they receive information about a death, the police visit the crime scene and write an inquest report. Then, they arrange for the body to be autopsied. However, most autopsies are performed by medical officers in government hospitals who lack specialised training in conducting autopsies. Although all Nepalese medical schools teach forensic medicine to undergraduate students and require them to witness some autopsies, most private institutions are not authorised to perform them. Autopsies performed without expertise can be subpar and, even when trained personnel are available, these facilities are inadequately equipped. In addition, there is a lack of sufficient manpower to provide expert medico-legal services. The Honourable Judges and District Attorneys of all district courts believe that the medico-legal reports prepared by the doctors are inappropriate, incomplete and inadequate for use as evidence in court. Moreover, the police are more concerned with establishing criminality than other aspects of medico-legal death investigation, such as autopsies. Therefore, the quality of medico-legal investigations, including death investigations, will not improve until government stakeholders recognise the importance of forensic medicine in the judiciary and for the resolution of crimes.

The tragic consequence of false honour: Understanding the phenomenon of "honour-killings" and its legal implications in Nepal.

"Honour-killings" are the intentional execution of women who are perceived to have disrespected their families; in Nepal this is frequently considered socially acceptable while the United Nations condemns them as arbitrary executions that violate the right to life. In Nepal, "honour-killing" is typically a caste-based hate crime which is not limited to women as there have been reports of male victims as well. The perpetrators are sentenced to life imprisonment for murder, with the perpetrator serving 25 years. Pride-killing is common in the animal kingdom, but there is no logic in killing a family member to maintain family pride in a civilised human society.

Assessment of quality of life (QOL) in cancer patients attending oncology unit of a Teaching Hospital in Bangladesh.

BACKGROUND: The quality of life (QoL) of a cancer patient is their perception of their physical, functional, psychological, and social well-being. QoL is one of the most important factors to consider when treating someone with cancer and during follow-up. The aim of this study was to understand the state of QoL among cancer patients in Bangladesh and to determine the factors that affect it. METHODS: This cross-sectional study was conducted on 210 cancer patients who attended the oncology unit of Delta Medical College & Hospital, Dhaka during the period between 1 May 2022 and 31 August 2022. Data were collected using the Bengali version of the European Organization for Research and Treatment of Cancer (EORTC) questionnaire. RESULTS: The study reported a high number of female cancer patients (67.6%), who were married, Muslims by religion, and non-residents of Dhaka. Breast cancer was more common among women (31.43%), while lung and upper respiratory tract cancer was more prevalent among men (19.05%). The majority of the patients (86.19%) were diagnosed with cancer in the past year. The overall mean score for functional scales was higher for physical functioning (54.92) whereas it was lower for social functioning (38.89). The highest score on the symptom scale was for financial problems (63.02), while the lowest was for diarrhea (33.01). The overall QoL score of cancer patients in the study was 47.98 and it was lower for males (45.71) compared to females (49.10). CONCLUSIONS: The overall QoL was poor among Bangladeshi cancer patients compared to those in developed countries. A low QoL score was observed for social and emotional functions. Financial difficulty was the main reason behind the lower QoL score on the symptom scale.

Suicide attempts due to child abuse: A perspective into the Nepalese legal framework and societal norms.

Children who experience violence are more prone to develop high-risk behaviour, mental illness and anxiety disorder. Nepalese law is against any form of physical violence but corporal punishment by parents on children continues in patriarchal Nepalese society. We describe a case of a young boy who attempted suicide twice due to maltreatment and discuss the legal and social issues involved.

Patients' awareness of their rights: An insight from a teaching hospital in Saudi Arabia.

BACKGROUND AND AIM: Knowledge and awareness of patients' rights are essential to reach the highest quality of care. In 2006, the Saudi Arabian government formulated "The Patients' Bill of Rights" to ensure that healthcare delivery is at its highest standard. Despite their efforts, several studies revealed patients' lack of awareness. In this study, we aim to investigate the patients' awareness of their rights according to the policy of a teaching hospital in Saudi Arabia. METHODS: A cross-sectional study was conducted where the participants (n= 384) were in-patients and out-patients of a tertiary care teaching hospital in the Eastern Province of Saudi Arabia. Informed consent was obtained, and confidentiality was maintained. The questionnaire consisted of 23 questions. Data were analyzed using Statistical Package Social Software version 26. RESULTS: Most of the participants were males (70.1%), in-patients (63.3%), and Saudi nationals (84.5%) with a mean age of 32 years. The mean awareness score was satisfactory (>7/14). However, more than half of the participants were unaware of their right to know the risks and benefits of treatment (55.1%), to know the identity of their healthcare providers (61.9%), to deny participation in research (58%), and appoint a healthcare proxy (64.8%). CONCLUSIONS: The present study revealed the lack of awareness of certain aspects of patients' rights that require action in the means of hospital awareness campaigns and educational materials. Further research is required to generalize a consensus on the Saudi population's level of awareness and consequent steps to optimize the delivery of healthcare in the country.

Video games and violence among children and adolescents in the Arab world: A systematic review.

BACKGROUND AND AIM: Video gaming has witnessed tremendous growth in recent years. Video games have been associated with various negative effects on players, such as aggressive behavior and reduced apathy. The present review aims to investigate the association between video games and violence among children and adolescents in the Arab world, while highlighting the influence of the type of video games played, time spent playing, and other possible associated factors. METHODS: A literature search was performed on PubMed and Web of Science electronic databases. All studies assessing video games and violence among children and adolescents written in English were eligible for inclusion in the review. A total of 9 studies were included in this systematic review. RESULTS: Six studies investigated the relationship between video games and aggression, five of which found a significant association. Several factors have been studied to assess their role in mediating the association between the two. A statistically significant association was found between aggression and age and sex of the players, with a predominance among early adolescents and males. Longer durations spent playing video games were found in three studies to be significantly associated with a greater risk of aggression. CONCLUSIONS: In the Arab world, studies addressing this subject are limited. The discrepancy of reported results between video games and amount of violence could be attributed to the lack of standardization across studies. Therefore, it becomes imperative to further explore the association through conclusive studies with standardized measures.(www.actabiomedica.it).

Emergency Physicians' Awareness of Medico-Legal Case Management: A Cross-Sectional Study from Saudi Arabia.

Background: Emergency department physicians often encounter medico-legal cases when patients initially present to the hospital, and thus there is a strong need for them to have robust medico-legal management and reporting knowledge. Objective: To assess the awareness of emergency department physicians of two major hospitals in the Eastern Province of Saudi Arabia in managing medico-legal cases. Methods: This descriptive cross-sectional survey-based study included all adult and pediatric emergency physicians working at King Fahd Hospital of the University and King Fahd Specialist Hospital, two major government hospitals in the Eastern Province of Saudi Arabia. The questionnaire included questions about demographic information, the workload in the emergency department, previous medico-legal training, and information about physicians' perspectives regarding medico-legal situations. Results: A total of 85 physicians completed the questionnaire, with most being Saudis (78.8%) and consultants (44.7%). Most participants (84.7%) immediately notified the police authority through the official procedure on suspicion of a case being criminal. However, only 28.2% of the participants were aware of how to complete the medico-legal report, and the majority (82.4%) had not received any specific training or attended specific courses in writing medico-legal reports. Most participants (91.8%) expressed the need for additional medico-legal case training programs, with continuous education (29.4%) being the preferred mode. In addition, 60% of the consultants were dissatisfied with the current medico-legal reporting and management workflow in their hospital. About half of the participants did not obtain photographs in medico-legal cases and did not know if their workplace provided a protocol for collecting evidentiary material such as clothes, swabs, bullets, remnants of foreign bodies, etc. Conclusions: The results of the present study indicate the necessity to consider periodical continuing medical education programs and workshops for emergency department physicians in the Eastern Province of Saudi Arabia to help them in appropriately handling medico-legal cases.

Bibliometric analysis of the literature on von Willebrand disease: Research status and trends.

BACKGROUND AND AIM: Von Willebrand disease (VWD) is considered the most prevalent inherited bleeding disorder. The current study aims to demonstrate the research status and trends on VWD worldwide. METHODS: Bibliometric analysis was used to investigate the global research productivity and trends on VWD. The publications on VWD from 1956 to 2021 were extracted using the Web of Science database. In the VWD domain, a total of 3,643 records were analyzed for authorship and collaboration patterns, yearly productivity, highly cited documents, relevant source of publication, most prolific scholars, productive countries, and organizations. RESULTS: The most productive journal, author, organization, and country were 'Haemophilia' with 439 publications, 'Favaloro EJ' with 119 publications, the 'University of Milan' with 192 publications, and the United States of America (USA) with 1,048 publications, respectively. The document with the highest citations was 'Srivastava A, 2013, Haemophilia,' which received 1,154 citations in total. In 2016, the highest number of publications shared by two author patterns was 28. With 199 publications, the year 2021 remained on the top, while the citation-wise analysis identified 2006 as the top year with 5,379 citations. CONCLUSIONS: Research productivity and publication trends on VWD revealed that the USA emerged as the most significant contributing country. The 'University of Milan' was the most significant contributing organization, while 'Favaloro EJ' was the most significant author. 'Hemophilia' was found to be the most significant journal in the field of VWD. It is recommended that researchers from countries with significant contributions to the field should collaborate with researchers from Asian countries and other countries that lack behind in research in the domain of VWD.(www.actabiomedica.it).

Asymptomatic pellet in the maxillary sinus: Medico-legal perspective.

Air guns used for plinking are weapons with a short range and low velocity. Because of their low velocity, the ammunition usually enters the body without causing any immediate life-threatening complications. Lead toxicity is a potential side effect of a pellet lodged in the body. However, there are cases where blood lead level was below the reference value even after decades of an air gun pellet remaining in the body. We report a case of 40-year-old man whose X-ray of the skull revealed a metallic foreign body that appeared to be an air gun pellet in the maxillary sinus. The patient recalled receiving a gunshot wound to his left cheek ten years ago. The wound healed, the pain subsided, and the patient was symptom-free, so he did not seek medical attention. The present case study illustrates the incidental finding of impacted foreign body and its medico-legal aspects in the Nepalese context.

Iatrogenic Causes of Cardiac Tamponade Resulting From Surgical Procedures: An Overview.

Cardiac tamponade is one of the most severely life-threatening emergencies encountered, mainly because of its significant impact on the pumping capacity of the heart by compressing the cardiac chambers due to the rapid accumulation of blood, fluid, pus, or clots in the pericardial sac. These accumulations may be collected following traumas, malignancies, uremia, and many other medical conditions as well as surgical procedures. Numerous errors and medicolegal aspects have been identified in diagnosing and treating cardiac tamponade associated with cardiac-related procedures such as valve replacement surgeries, cardiac pacemaker implantation, pericardiocentesis, and other non-cardiac related procedures such as peri-hiatal surgeries. Patients taking anticoagulants or anticancer medications are especially susceptible to developing cardiac tamponade when undergoing surgical procedures, raising the question of preoperative screening to avoid errors. Misdiagnosis, treatment delay or failure to deliver the utmost quality of treatment, lack of complication screening and follow-ups for those at risk, surgeons rushing to complete cases, burnout, and other human factors are predispositions to the development of cardiac tamponade. Fortunately, most of these errors occurring within healthcare settings are avoidable and must be prevented for eliminating any risks to reduce the incidence and mortality of cardiac tamponade cases resulting from iatrogenic etiology. It is an intricate condition where precision and caution are crucial.

Postmortem Genetic Testing in Sudden Unexpected Death: A Narrative Review.

Sudden unexpected death (SUD) is one of the challenging situations encountered in forensic medicine. As a rule, a comprehensive forensic assessment is performed to identify the cause of death in such cases; however, the absence of findings suggestive of a cause, i.e., a negative autopsy, warrants further investigation such as a molecular autopsy. In this review, we aim to highlight the genetic causes of SUD, tools used in a molecular autopsy, and the role of screening in surviving relatives. As per several guidelines, the most preferred samples for DNA extraction are whole blood and fresh frozen tissues. Furthermore, Sanger sequencing and next-generation sequencing are the technologies that are used for genetic analysis; the latter overcomes the former's drawbacks in terms of cost-effectiveness, time consumption, and the ability to sequence the whole exome. SUD have diverse etiologies; we can generally classify them into cardiac and non-cardiac causes. Regarding cardiac causes, many conditions having an underlying genetic basis are included, such as channelopathies and cardiomyopathies. Regarding non-cardiac causes of SUD, the main etiologies are epilepsy and metabolic disorders. Nevertheless, it has been proposed that there is a genetic overlap between channelopathies, especially long QT syndromes and epilepsy. Additionally, fatty acid oxidation disorders are major metabolic conditions that are caused by certain genetic mutations that can lead to SUD in infancy. Since many SUD causes have an underlying genetic mutation, it is important to understand the genetic variations not only to recognize the cause of death but also to undertake further preventive measures for surviving relatives. In conclusion, a molecular autopsy has a major role in the forensic examination of cases of SUD.

The Use of Volatile Substances in Drug-Facilitated Sexual Assault: A Systematic Review.

Drug-facilitated sexual assault (DFSA) is a significant crime that is increasing in incidence. The employment of volatile substances such as chloroform and aromatic petroleum hydrocarbons in DFSAs is quite an unusual choice. The objective of this review is to explore the use of volatile substances in DFSAs. Using the PubMed database, a systematic review of the literature was conducted. Thereafter, citation searching was carried out within the included studies from the primary search. A total of five studies were eligible for inclusion. Chloroform was the drug used in the DFSA in three of the included studies, and aromatic hydrocarbons in the remaining two. Two of the offenders who employed chloroform possessed a unique way to access the drug: their degrees. The evidence found in the DFSA cases included a chloroform-scented scarf and a solvent-immersed cloth. Headspace gas chromatography-mass spectrometry, liquid chromatography-electrospray coupled tandem mass spectrometry, toxicology assays of blood and urine, and solvent or hydrocarbon gas chromatography flame-ionization detection followed by gas chromatography-mass spectrometry were among the investigations performed to detect the volatile substances. The implementation of stricter regulations on chloroform for employees in chemical industries and laboratories is recommended. In cases where the autopsy is unclear and there are conspicuous facial and airway injuries, it is prudent to collect an early sample for volatile substance analysis.
