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.

Medical Students' Perceptions Towards Online Teaching During the Covid-19 Pandemic: A Cross-Sectional Study from Saudi Arabia

Background

The Covid-19 has made a huge impact on higher education. Online teaching and learning became essential to deliver educational activities in all areas including medical education. In this study, we aimed to investigate medical students' perceptions on the role of online teaching and learning in facilitating medical education.

Material and Methods

A cross-sectional study using a self-administered online questionnaire was conducted. Students eligible were medical students across all years at Imam Abdulrahman Bin Faisal University, Saudi Arabia. Perceptions analysis was conducted using SPSS software.

Results

A total of 563 students participated in the study (prominent category female 64%, n = 361). There was a significant increase in the number of hours devoted to online learning during the pandemic. Live lectures/tutorials platform via zoom showed the highest rate of interaction compared to pre-recorded lectures and learning materials uploaded on blackboard. 50% of the students disagreed that online teaching is as effective as face-to-face teaching. The greatest perceived enjoyable aspect included the online accessibility of materials. Whereas the most frequent perceived barrier to online learning included internet connection. 17% of students reflected a poor understanding of scientific materials through online PBL. More than 50% of students revealed that online theoretical lectures are as good as classroom or better. Whereas the majority (70%) were unable to learn clinical skills online. The results indicated high impact on students' physical activities (80%). Impacts were higher on pre-clinical students' health and social life than on clinical students.

Conclusion

Our findings reported that during emergency situations due to the pandemic, online teaching enables the continuity of medical education and provides adequate efficiency. The use of live online platforms showed high level of interaction. However, some barriers need to be addressed especially at the clinical skills development level to maximize the benefit of online teaching and learning.

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.

Stature estimation from the hand dimensions in the Eastern Saudi Arabian adult male population

BACKGROUND AND AIM

Anthropometry is widely used in preliminary forensic investigations involving the identification of unknown dismembered body parts. Stature estimation is an important indicator of forensic identification considered during such initial investigations. Different populations have different body sizes and proportions that affect the forensic anthropometric estimation of stature. Hence, the need for population-specific databases and analyses. The present study was conducted with the objective of estimating stature from the hand dimensions in the Eastern Saudi Arabian adult male population.

METHODS

The present study included 200 Eastern Saudi Arabian males aged from 20 to 56 years. Stature and hand dimensions of hand length, palm length, and hand breadth were measured as per standard anthropometric procedures. Linear and multiple regression equations were derived to estimate stature from the aforementioned hand dimensions.

RESULTS

Correlation coefficients between stature and the aforementioned hand dimensions were found to be statistically significant. The hand length and palm length showed higher correlation coefficients than the hand breadth. Single variable linear regression and multi-variable linear regression equations were derived to estimate stature from the hand dimensions. Higher correlation coefficients were obtained for multi-variable linear regression than single variable linear regressions.

CONCLUSIONS

In conclusion, hand dimensions can be used as a reliable predictor to estimate stature in the Eastern Saudi Arabian adult male population. (www.actabiomedica.it).

Postmortem findings in COVID-19 fatalities: A systematic review of current evidence

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the ongoing pandemic of coronavirus disease 2019 (COVID-19). Almost 17 months after the first COVID-19 case was reported, the exact pathogenesis of the virus is still open to interpretation. Postmortem studies have been relatively scarce due to the high infectivity rate of the virus. We systematically reviewed the literature available for studies that reported gross, histological, microscopic, and immunohistochemical findings in COVID-19 fatalities with the aim of reporting any recurrent findings among different demographics. PubMed and Scopus were searched up till the second of May 2021 and 46 studies with a total of 793 patients were shortlisted after the application of inclusion and exclusion criteria. The selected studies reported gross, histological, microscopic, and immunohistochemical autopsy findings in the lungs, heart, liver, gallbladder, bowels, kidney, spleen, bone marrow, lymph nodes, CNS, pancreas, endocrine/exocrine glands, and a few other miscellaneous locations. The SARS-CoV-2 virus was detected in multiple organs and so was the presence of widespread microthrombi. This finding suggests that the pathogenesis of this highly infectious virus might be linked to some form of coagulopathy. Further studies should focus on analyzing postmortem findings in a larger number of patients from different demographics in order to obtain more generalizable results.

Research trends in forensic anthropology: A bibliometric analysis

This paper aims to examine the worldwide research development and trends in forensic anthropology by using bibliometric analysis. Scopus database was used to identify published papers on forensic anthropology from 1948 to 2020. A total of 4,499 records were analyzed for yearly publication productivity, authorship and citation pattern, types of documents, most productive journals, organizations, authors, and countries, frequently cited papers, most used keywords, countries of collaboration, and three-field plot analysis in the domain of forensic anthropology. The results indicated that the highest grand total publications were between the years 2016 and 2019, while the highest multi-authored publications were in the year 2018. The most productive journal, author, organization, and country were the 'Journal of Forensic Sciences' with grand total publications of 934, 'Cattaneo, C.' with 97 publications, 'Centre National de la Recherche Scientifique' with 130 publications, and the United States with 1020 total cited papers, respectively. The document with the highest number of citations was 'Buckberry and Chamberlain, 2002, Am J Phys Anthropol' with a total of 387. Three-field plot analysis regarding the most outstanding keyword-source-country was "Forensic anthropology"- "Journal of Forensic Sciences" and "Forensic Science International"- "USA", "France", and "UK". The predomination of certain countries over others in the field of forensic anthropology limits its prosperity as ethnic variety is of important regard. Research collaborations were mainly observed between the United States and European countries, which highlights the need for strengthening collaborations between developed and developing nations.

Workplace hazards in forensic mortuaries in Saudi Arabia: A survey of forensic mortuary personnel

Forensic mortuaries have always presented a potential threat to workers who come into contact with dead bodies. This research aims to identify hazards faced by forensic mortuary personnel, including forensic pathologists and technicians working in forensic mortuaries in forensic medicine centres throughout Saudi Arabia, to recognise the prevalence of exposure to workplace hazards and to discover the degree of awareness and use of safety practices. A descriptive, cross-sectional study was conducted in a total of 20 forensic medicine centres, using an online questionnaire distributed among forensic mortuary personnel. A total of 113 participants responded to the questionnaire. Just over half (53%) of workplaces always provided personal protective equipment, and 75% of participants always used them. The most common hazards were needle-prick wounds and accidental slips or falls. Almost two thirds (64%) of participants witnessed or experienced a work-related accident in the forensic mortuary. The lack of previous studies concerning hazard exposure among forensic mortuary personnel in Saudi Arabia means that this study provides foundational evidence for future research concerning forensic autopsy-related work accidents in Saudi Arabia.

Characteristics of Medico-Legal Cases and Errors in Medico-Legal Reports at a Teaching Hospital in Saudi Arabia

Introduction

A medico-legal case (MLC) involves any injury or medical condition in which law enforcement agencies investigate and fix the responsibility regarding of an injury or medical condition. Incorrect or incomplete medico-legal reports (MLRs) may trigger a pause or delay in legal proceedings and patients’ rights could be violated. The aim of this study is to describe the characteristics of MLCs and to identify errors in the MLRs.

Materials and Methods

This retrospective, descriptive study was conducted in a teaching hospital in the Eastern Province of Saudi Arabia. In total, 418 MLRs furnished during a 6-month period and reviewed for characteristics of MLCs and identification of errors.

Results

A total of 418 MLRs were included in the present study. Fights or physical assault and battery formed the major proportion of MLCs amounting to 83% of MLCs. Blunt injury was the dominant type of injury in most of the cases (81.8%). In relation to errors in MLRs, no MLR in the present study were without errors.

Conclusion

Fights or physical assault and battery formed the major proportion of MLCs. Multiple errors were identified in the MLRs furnished by the physicians. Writing MLRs must follow standardized guidelines as it has a bearing on legal proceedings and patients’ rights. We recommend training for physicians in writing MLRs in the interest of proper administration of justice.

Medical Students’ Knowledge of the Cause-of-Death Certification: A Descriptive, Cross-Sectional Study from Saudi Arabia

Background

The medical certificate of cause-of-death is an important document of medicolegal significance. Errors in the completion of the death certificate by doctors are not uncommon. Therefore, it is important for medical students, the future doctors, to be trained in completing the medical certificate of cause-of-death. This study aimed to investigate the understanding of final-year medical students of the cause-of-death certification and to assess their ability to complete the cause-of-death statement.

Material and Methods

The final-year medical students of Imam Abdulrahman Bin Faisal University, of the academic year 2020–21 formed the cohort of medical students that participated in the current descriptive, cross-sectional study wherein a self-administered online questionnaire was used.

Results

A total of 174 students provided complete responses. The immediate cause of death in the given case scenario was answered correctly by 107 (61.5%) of the students. The underlying cause of death was answered correctly by only 20 (11.5%) students. It was apparent that the chain of events leading to death in the given case scenario was wrongly understood by the majority of the students. Nonetheless, the other significant condition contributing to death was answered correctly by 151 (86.8%) students. Other errors included the use of abbreviations, mention of the mechanism of death as a cause of death, mention of clinical features or irrelevant causes of death and mention of the incorrect time interval between the onset of a cause of death and death.

Conclusion

The current study found that the overall performance of final-year medical students was reasonably good except for the fact that most misunderstood the underlying cause of death in the given case scenario. The majority of the students had attended a tutorial on medical certification of cause-of-death before participating in the current study, which suggests that continuous training might be required.

Burden of Transport-Related Injuries in the Eastern Mediterranean Region: A Systematic Analysis for the Global Burden of Disease Study 2017

BACKGROUND

Transport-related injuries (TIs) are a substantial public health concern for all regions of the world. The present study quantified the burden of TIs and deaths in the Eastern Mediterranean region (EMR) in 2017 by sex and age.

METHODS

TIs and deaths were estimated by age, sex, country, and year using Cause of Death Ensemble modelling (CODEm) and DisMod-MR 2.1. Disability-adjusted life years (DALYs), which quantify the total burden of years lost due to premature death or disability, were also estimated per 100000 population. All estimates were reported along with their corresponding 95% uncertainty intervals (UIs).

RESULTS

In 2017, there were 5.5 million (UI 4.9-6.2) transport-related incident cases in the EMR - a substantial increase from 1990 (2.8 million; UI 2.5-3.1). The age-standardized incidence rate for the EMR in 2017 was 787 (UI 705.5-876.2) per 100000, which has not changed significantly since 1990 (-0.9%; UI -4.7 to 3). These rates differed remarkably between countries, such that Oman (1303.9; UI 1167.3-1441.5) and Palestine (486.5; UI 434.5-545.9) had the highest and lowest age-standardized incidence rates per 100000, respectively. In 2017, there were 185.3 thousand (UI 170.8-200.6) transport-related fatalities in the EMR - a substantial increase since 1990 (140.4 thousand; UI 118.7-156.9). The age-standardized death rate for the EMR in 2017 was 29.5 (UI 27.1-31.9) per 100000, which was 30.5% lower than that found in 1990 (42.5; UI 36.8-47.3). In 2017, Somalia (54; UI 30-77.4) and Lebanon (7.1; UI 4.8-8.6) had the highest and lowest age-standardized death rates per 100,000, respectively. The age-standardised DALY rate for the EMR in 2017 was 1,528.8 (UI 1412.5-1651.3) per 100000, which was 34.4% lower than that found in 1990 (2,331.3; UI 1,993.1-2,589.9). In 2017, the highest DALY rate was found in Pakistan (3454121; UI 2297890- 4342908) and the lowest was found in Bahrain (8616; UI 7670-9751).

CONCLUSION

The present study shows that while road traffic has become relatively safer (measured by deaths and DALYs per 100000 population), the number of transport-related fatalities in the EMR is growing and needs to be addressed urgently.

Homicidal Pesticide Poisoning - An Overview

Pesticides are chemical or biological agents used to repel or kill pests. Pesticides are potent and lethal toxic substances that are also being infamously used for homicidal purposes due to their easy availability and rapid action. In this review, we look at 21 articles related to homicidal pesticide poisoning in the literature with an emphasis on fatal doses, routes of administration, and profiles of victims and perpetrators. Organophosphates and rodenticides were the most commonly used classes of pesticides, and ingestion was the most common route of administration; however, other modes of administration, such as through intraperitoneal injection, were also reported. Interestingly, we have noticed that victims involved in homicidal poisoning were mostly in close relationships with perpetrators. Most perpetrators were either spouses or other immediate family members. Abiding by the regulations that govern the production, sale, and use of pesticides and proper documentation of the related trail can help control the prevalence of homicidal pesticide poisoning. Recognition of the distinct morbid anatomy of the poisoning cases, alongside a high index of suspicion in cases that fit the profile, is essential for forensic analysis.

Pulmonary tuberculosis in a cohort of forensic autopsies: a preliminary study from Saudi Arabia

Aims

The purpose of this study was to identify any cases of previously undiagnosed pulmonary tuberculosis during autopsy.

Methods

This prospective study investigated a cohort of deceased individuals that underwent a full external and internal postmortem examination at the Forensic Medicine Centre, Dammam, Saudi Arabia. Gross pathology, histopathology and molecular pathology were used to identify pulmonary tuberculosis in forensic autopsy samples from the lungs.

Results

A total of 82 cases autopsied were included in the study. The mean ± SD age of the study cohort was 35.5 ± 10.3 years (range, 20–80 years). Males (n = 70; 85.37%) outnumbered females. The deceased were from 15 different countries. The number of Saudis was 16 (19.51%). The maximum number of non-Saudis was from India with 26 cases (31.71%). There were no cases of undiagnosed pulmonary tuberculosis detected for the first time at autopsy.

Conclusions

Although the prevalence of pulmonary tuberculosis in forensic autopsy cases in this preliminary study was nil, we recommend further studies to be conducted on a larger scale and in different autopsy centres throughout Saudi Arabia to get an insight into the burden of clinically undiagnosed tuberculosis in the entire country.

Measuring universal health coverage based on an index of effective coverage of health services in 204 countries and territories, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Achieving universal health coverage (UHC) involves all people receiving the health services they need, of high quality, without experiencing financial hardship. Making progress towards UHC is a policy priority for both countries and global institutions, as highlighted by the agenda of the UN Sustainable Development Goals (SDGs) and WHO's Thirteenth General Programme of Work (GPW13). Measuring effective coverage at the health-system level is important for understanding whether health services are aligned with countries' health profiles and are of sufficient quality to produce health gains for populations of all ages.

METHODS

Based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we assessed UHC effective coverage for 204 countries and territories from 1990 to 2019. Drawing from a measurement framework developed through WHO's GPW13 consultation, we mapped 23 effective coverage indicators to a matrix representing health service types (eg, promotion, prevention, and treatment) and five population-age groups spanning from reproductive and newborn to older adults (≥65 years). Effective coverage indicators were based on intervention coverage or outcome-based measures such as mortality-to-incidence ratios to approximate access to quality care; outcome-based measures were transformed to values on a scale of 0-100 based on the 2·5th and 97·5th percentile of location-year values. We constructed the UHC effective coverage index by weighting each effective coverage indicator relative to its associated potential health gains, as measured by disability-adjusted life-years for each location-year and population-age group. For three tests of validity (content, known-groups, and convergent), UHC effective coverage index performance was generally better than that of other UHC service coverage indices from WHO (ie, the current metric for SDG indicator 3.8.1 on UHC service coverage), the World Bank, and GBD 2017. We quantified frontiers of UHC effective coverage performance on the basis of pooled health spending per capita, representing UHC effective coverage index levels achieved in 2019 relative to country-level government health spending, prepaid private expenditures, and development assistance for health. To assess current trajectories towards the GPW13 UHC billion target-1 billion more people benefiting from UHC by 2023-we estimated additional population equivalents with UHC effective coverage from 2018 to 2023.

FINDINGS

Globally, performance on the UHC effective coverage index improved from 45·8 (95% uncertainty interval 44·2-47·5) in 1990 to 60·3 (58·7-61·9) in 2019, yet country-level UHC effective coverage in 2019 still spanned from 95 or higher in Japan and Iceland to lower than 25 in Somalia and the Central African Republic. Since 2010, sub-Saharan Africa showed accelerated gains on the UHC effective coverage index (at an average increase of 2·6% [1·9-3·3] per year up to 2019); by contrast, most other GBD super-regions had slowed rates of progress in 2010-2019 relative to 1990-2010. Many countries showed lagging performance on effective coverage indicators for non-communicable diseases relative to those for communicable diseases and maternal and child health, despite non-communicable diseases accounting for a greater proportion of potential health gains in 2019, suggesting that many health systems are not keeping pace with the rising non-communicable disease burden and associated population health needs. In 2019, the UHC effective coverage index was associated with pooled health spending per capita (r=0·79), although countries across the development spectrum had much lower UHC effective coverage than is potentially achievable relative to their health spending. Under maximum efficiency of translating health spending into UHC effective coverage performance, countries would need to reach $1398 pooled health spending per capita (US$ adjusted for purchasing power parity) in order to achieve 80 on the UHC effective coverage index. From 2018 to 2023, an estimated 388·9 million (358·6-421·3) more population equivalents would have UHC effective coverage, falling well short of the GPW13 target of 1 billion more people benefiting from UHC during this time. Current projections point to an estimated 3·1 billion (3·0-3·2) population equivalents still lacking UHC effective coverage in 2023, with nearly a third (968·1 million [903·5-1040·3]) residing in south Asia.

INTERPRETATION

The present study demonstrates the utility of measuring effective coverage and its role in supporting improved health outcomes for all people-the ultimate goal of UHC and its achievement. Global ambitions to accelerate progress on UHC service coverage are increasingly unlikely unless concerted action on non-communicable diseases occurs and countries can better translate health spending into improved performance. Focusing on effective coverage and accounting for the world's evolving health needs lays the groundwork for better understanding how close-or how far-all populations are in benefiting from UHC.

Global age-sex-specific fertility, mortality, healthy life expectancy (HALE), and population estimates in 204 countries and territories, 1950-2019: a comprehensive demographic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Accurate and up-to-date assessment of demographic metrics is crucial for understanding a wide range of social, economic, and public health issues that affect populations worldwide. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 produced updated and comprehensive demographic assessments of the key indicators of fertility, mortality, migration, and population for 204 countries and territories and selected subnational locations from 1950 to 2019.

METHODS

8078 country-years of vital registration and sample registration data, 938 surveys, 349 censuses, and 238 other sources were identified and used to estimate age-specific fertility. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate age-specific fertility rates for 5-year age groups between ages 15 and 49 years. With extensions to age groups 10-14 and 50-54 years, the total fertility rate (TFR) was then aggregated using the estimated age-specific fertility between ages 10 and 54 years. 7417 sources were used for under-5 mortality estimation and 7355 for adult mortality. ST-GPR was used to synthesise data sources after correction for known biases. Adult mortality was measured as the probability of death between ages 15 and 60 years based on vital registration, sample registration, and sibling histories, and was also estimated using ST-GPR. HIV-free life tables were then estimated using estimates of under-5 and adult mortality rates using a relational model life table system created for GBD, which closely tracks observed age-specific mortality rates from complete vital registration when available. Independent estimates of HIV-specific mortality generated by an epidemiological analysis of HIV prevalence surveys and antenatal clinic serosurveillance and other sources were incorporated into the estimates in countries with large epidemics. Annual and single-year age estimates of net migration and population for each country and territory were generated using a Bayesian hierarchical cohort component model that analysed estimated age-specific fertility and mortality rates along with 1250 censuses and 747 population registry years. We classified location-years into seven categories on the basis of the natural rate of increase in population (calculated by subtracting the crude death rate from the crude birth rate) and the net migration rate. We computed healthy life expectancy (HALE) using years lived with disability (YLDs) per capita, life tables, and standard demographic methods. Uncertainty was propagated throughout the demographic estimation process, including fertility, mortality, and population, with 1000 draw-level estimates produced for each metric.

FINDINGS

The global TFR decreased from 2·72 (95% uncertainty interval [UI] 2·66-2·79) in 2000 to 2·31 (2·17-2·46) in 2019. Global annual livebirths increased from 134·5 million (131·5-137·8) in 2000 to a peak of 139·6 million (133·0-146·9) in 2016. Global livebirths then declined to 135·3 million (127·2-144·1) in 2019. Of the 204 countries and territories included in this study, in 2019, 102 had a TFR lower than 2·1, which is considered a good approximation of replacement-level fertility. All countries in sub-Saharan Africa had TFRs above replacement level in 2019 and accounted for 27·1% (95% UI 26·4-27·8) of global livebirths. Global life expectancy at birth increased from 67·2 years (95% UI 66·8-67·6) in 2000 to 73·5 years (72·8-74·3) in 2019. The total number of deaths increased from 50·7 million (49·5-51·9) in 2000 to 56·5 million (53·7-59·2) in 2019. Under-5 deaths declined from 9·6 million (9·1-10·3) in 2000 to 5·0 million (4·3-6·0) in 2019. Global population increased by 25·7%, from 6·2 billion (6·0-6·3) in 2000 to 7·7 billion (7·5-8·0) in 2019. In 2019, 34 countries had negative natural rates of increase; in 17 of these, the population declined because immigration was not sufficient to counteract the negative rate of decline. Globally, HALE increased from 58·6 years (56·1-60·8) in 2000 to 63·5 years (60·8-66·1) in 2019. HALE increased in 202 of 204 countries and territories between 2000 and 2019.

INTERPRETATION

Over the past 20 years, fertility rates have been dropping steadily and life expectancy has been increasing, with few exceptions. Much of this change follows historical patterns linking social and economic determinants, such as those captured by the GBD Socio-demographic Index, with demographic outcomes. More recently, several countries have experienced a combination of low fertility and stagnating improvement in mortality rates, pushing more populations into the late stages of the demographic transition. Tracking demographic change and the emergence of new patterns will be essential for global health monitoring.

Suicidal Ideation Among Medical Students in Dammam, Saudi Arabia

Background: Medical students are at high risk of suicidal ideation. Aim: We aimed to obtain information on suicidal ideation among medical students in Dammam located in the Eastern Province of Saudi Arabia. Method: This cross-sectional study was conducted at the College of Medicine affiliated with Imam Abdulrahman Bin Faisal University in the Eastern Province of Saudi Arabia. Suicidal ideation in the past 12 months was assessed based on responses to four questions in the depression subscale of the General Health Questionnaire 28 (GHQ-28). In addition, data were collected to examine the association of suicidal ideation with various factors. Results: We found that 1 in 3 medical students in the study had suicidal ideation in the past 12 months, while around 40% had lifetime suicidal ideation. Suicidal ideation was associated with feelings of parental neglect, history of physical abuse, and dissatisfaction with academic performance. Limitations: The cross-sectional nature of this study limits its ability to determine causality regarding suicidal ideation. Conclusion: These rates are considerably high when compared with rates from studies in other countries around the world. This study provides a reference in the field of suicidology for this region of Saudi Arabia.

Estimating global injuries morbidity and mortality: methods and data used in the Global Burden of Disease 2017 study

BACKGROUND

While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria.

METHODS

In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation. In summary, these methods included estimating cause-specific mortality for every cause of injury, and then estimating incidence for every cause of injury. Non-fatal disability for each cause is then calculated based on the probabilities of suffering from different types of bodily injury experienced.

RESULTS

GBD 2017 produced morbidity and mortality estimates for 38 causes of injury. Estimates were produced in terms of incidence, prevalence, years lived with disability, cause-specific mortality, years of life lost and disability-adjusted life-years for a 28-year period for 22 age groups, 195 countries and both sexes.

CONCLUSIONS

GBD 2017 demonstrated a complex and sophisticated series of analytical steps using the largest known database of morbidity and mortality data on injuries. GBD 2017 results should be used to help inform injury prevention policy making and resource allocation. We also identify important avenues for improving injury burden estimation in the future.

Epidemiology of injuries from fire, heat and hot substances: global, regional and national morbidity and mortality estimates from the Global Burden of Disease 2017 study

BACKGROUND

Past research has shown how fires, heat and hot substances are important causes of health loss globally. Detailed estimates of the morbidity and mortality from these injuries could help drive preventative measures and improved access to care.

METHODS

We used the Global Burden of Disease 2017 framework to produce three main results. First, we produced results on incidence, prevalence, years lived with disability, deaths, years of life lost and disability-adjusted life years from 1990 to 2017 for 195 countries and territories. Second, we analysed these results to measure mortality-to-incidence ratios by location. Third, we reported the measures above in terms of the cause of fire, heat and hot substances and the types of bodily injuries that result.

RESULTS

Globally, there were 8 991 468 (7 481 218 to 10 740 897) new fire, heat and hot substance injuries in 2017 with 120 632 (101 630 to 129 383) deaths. At the global level, the age-standardised mortality caused by fire, heat and hot substances significantly declined from 1990 to 2017, but regionally there was variability in age-standardised incidence with some regions experiencing an increase (eg, Southern Latin America) and others experiencing a significant decrease (eg, High-income North America).

CONCLUSIONS

The incidence and mortality of injuries that result from fire, heat and hot substances affect every region of the world but are most concentrated in middle and lower income areas. More resources should be invested in measuring these injuries as well as in improving infrastructure, advancing safety measures and ensuring access to care.

Global injury morbidity and mortality from 1990 to 2017: results from the Global Burden of Disease Study 2017

BACKGROUND

Past research in population health trends has shown that injuries form a substantial burden of population health loss. Regular updates to injury burden assessments are critical. We report Global Burden of Disease (GBD) 2017 Study estimates on morbidity and mortality for all injuries.

METHODS

We reviewed results for injuries from the GBD 2017 study. GBD 2017 measured injury-specific mortality and years of life lost (YLLs) using the Cause of Death Ensemble model. To measure non-fatal injuries, GBD 2017 modelled injury-specific incidence and converted this to prevalence and years lived with disability (YLDs). YLLs and YLDs were summed to calculate disability-adjusted life years (DALYs).

FINDINGS

In 1990, there were 4 260 493 (4 085 700 to 4 396 138) injury deaths, which increased to 4 484 722 (4 332 010 to 4 585 554) deaths in 2017, while age-standardised mortality decreased from 1079 (1073 to 1086) to 738 (730 to 745) per 100 000. In 1990, there were 354 064 302 (95% uncertainty interval: 338 174 876 to 371 610 802) new cases of injury globally, which increased to 520 710 288 (493 430 247 to 547 988 635) new cases in 2017. During this time, age-standardised incidence decreased non-significantly from 6824 (6534 to 7147) to 6763 (6412 to 7118) per 100 000. Between 1990 and 2017, age-standardised DALYs decreased from 4947 (4655 to 5233) per 100 000 to 3267 (3058 to 3505).

INTERPRETATION

Injuries are an important cause of health loss globally, though mortality has declined between 1990 and 2017. Future research in injury burden should focus on prevention in high-burden populations, improving data collection and ensuring access to medical care.

The Islamic perspective on physician-assisted suicide and euthanasia

Physician-assisted suicide (PAS) and euthanasia can be debated from ethical and legal perspectives, and there are a variety of views regarding their acceptability and usefulness. Religion is considered an important factor in determining attitudes towards such practices. This narrative review aims to provide an overview of the Islamic perspective on PAS and euthanasia and explore the Islamic approach in addressing the related issues. The PubMed database was searched to retrieve relevant articles, then the references listed in the selected articles were checked for additional relevant publications. Additionally, religious books (Quran and hadith) and legal codes of selected countries were also consulted from appropriate websites. The Islamic code of law discusses many issues regarding life and death, as it considers any act of taking one's life to be forbidden. Islam sanctifies life and depicts it as a gift from God (Allah). It consistently emphasises the importance of preserving life and well-being. Therefore Muslims, the followers of Islam, have no right to end their life. All Islamic doctrines consider PAS and euthanasia to be forbidden. However, if the patient has an imminently fatal illness, withholding or withdrawing a futile medical treatment is considered permissible. From a legal perspective, Islamic countries have not legalised PAS and euthanasia. Such practices are therefore considered suicides when patients consent to the procedure, and homicides when physicians execute the procedure.

Histologic Reliability of Tissues from Embalmed Cadavers: Can They be Useful in Medical Education?

Background:

Current trends in medical curricula are shifting from teaching histology and pathology as stand-alone disciplines. Therefore, it would be useful to examine the potential value of integrating these into the anatomical dissection experience.

Objectives:

The aim of this study was to assess the histologic reliability of tissues taken from embalmed cadavers in an anatomy laboratory.

Materials and Methods:

A total of 112 tissue samples were obtained using standard autopsy techniques from various organs (heart, lung, thyroid, skeletal muscle, bone and skin) of 11 cadavers available at the anatomy laboratory of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia, in 2019. Samples were prepared using the standard paraffin procedure followed by cutting sections at 4-μm thickness and staining with standard hematoxylin and eosin stain. Using predefined criteria, the quality of the samples was evaluated by two board-certified histopathologists and each slide was categorized as good, satisfactory or poor.

Results:

Overall, 34.2% and 60.3% of the slides were of good and satisfactory quality, respectively. A significant difference in tissue quality was found between various organs. Thick skin and bone tissues had the highest “good” rating (84.6% and 81.8%, respectively), while thyroid and lung tissues had the highest “poor” rating (20% and 13.6%, respectively).

Conclusion:

Most of the tissues acquired from the embalmed cadavers were of good or satisfactory quality, thereby indicating the beneficial use of histological tissue from cadavers for educational purposes. Future research into how these findings translate into meaningful medical education would be beneficial.

Landmark publications on Sudden Infant Death Syndrome: A bibliometrics analysis

Sudden infant death syndrome (SIDS) is a poorly understood disorder, and its pathophysiology and risk factors remain unclear. Research in the area is the key to combating the pervasive prevalence of this fatal disorder. We sought to identify the top 50 articles concerning SIDS and study their bibliometric characteristics to gain an insight into the research trends in this area. Using the Scopus database, two independent reviewers conducted a literature search using a prespecified search string. Results were arranged according to the citation count, and the top 50 relevant articles were selected. No time restrictions were set, and all types of articles were included. A detailed analysis was carried out to identify the trends and characteristics of the top 50 articles. The top 50 articles were published between 1972 and 2011, with the most productive 5-year interval being 1991-1995. These 50 papers accumulated a total of 13,703 citations (median = 236 citations per paper). Among these, about 9% were self-citations. The citations received by these core papers seemed to decline post-2009. The top 50 articles were published in 21 different journals, with Pediatrics contributing the most (n = 15). US authors were listed for 60% of the articles (n = 30). None of the articles originated from Asian authors. Our manuscript highlights the characteristics of impactful articles on SIDS - and this can act as a directive for researchers aiming to publish on this topic. Bibliometric parameters suggest a decreasing research interest in the fi eld of SIDS, which is concerning, and efforts should be made to promote research. Furthermore, the lack of influential research from Asian authors is also troubling. Funding should preferably be directed toward Asian researchers to bridge the gap in knowledge.

The burden of unintentional drowning: global, regional and national estimates of mortality from the Global Burden of Disease 2017 Study

Background

Drowning is a leading cause of injury-related mortality globally. Unintentional drowning (International Classification of Diseases (ICD) 10 codes W65-74 and ICD9 E910) is one of the 30 mutually exclusive and collectively exhaustive causes of injury-related mortality in the Global Burden of Disease (GBD) study. This study’s objective is to describe unintentional drowning using GBD estimates from 1990 to 2017.

Methods

Unintentional drowning from GBD 2017 was estimated for cause-specific mortality and years of life lost (YLLs), age, sex, country, region, Socio-demographic Index (SDI) quintile, and trends from 1990 to 2017. GBD 2017 used standard GBD methods for estimating mortality from drowning.

Results

Globally, unintentional drowning mortality decreased by 44.5% between 1990 and 2017, from 531 956 (uncertainty interval (UI): 484 107 to 572 854) to 295 210 (284 493 to 306 187) deaths. Global age-standardised mortality rates decreased 57.4%, from 9.3 (8.5 to 10.0) in 1990 to 4.0 (3.8 to 4.1) per 100 000 per annum in 2017. Unintentional drowning-associated mortality was generally higher in children, males and in low-SDI to middle-SDI countries. China, India, Pakistan and Bangladesh accounted for 51.2% of all drowning deaths in 2017. Oceania was the region with the highest rate of age-standardised YLLs in 2017, with 45 434 (40 850 to 50 539) YLLs per 100 000 across both sexes.

Conclusions

There has been a decline in global drowning rates. This study shows that the decline was not consistent across countries. The results reinforce the need for continued and improved policy, prevention and research efforts, with a focus on low- and middle-income countries.

Clinicians' Attitudes Towards Do-Not-Resuscitate Directives in a Teaching Hospital in Saudi Arabia

The Do-Not-Resuscitate (DNR) directive has provided a major leap in end-of-life care. To demonstrate the factors influencing physicians' DNR decisions in King Fahd University Hospital in the Eastern Province of Saudi Arabia, 42 physicians from the medical and surgical departments of the same center were requested to participate in a cross-sectional survey. Thirty-six questionnaires were completed and returned from a total of 42 distributed among physicians, making a response rate of 85.7%. Certain diagnostic categories increase the likelihood of issuing a DNR order for a patient. Neurological (58.3%) and cardiovascular (41.7%) diseases were the highest response among other diseases in influencing physicians' decisions. In addition, other factors like lack of comorbidities (55.5%), age (52.7%), and previous intensive care unit (ICU) admissions and resuscitation (44.4%) showed an effect on the directive decisions of DNR among investigated physicians. However, weak palliative care in the hospital (11.1%), religious beliefs (5.5%), and gender (2.7%) were the least associated factors affecting physicians' DNR decisions. This study addresses the influencing factors of DNR orders issuance among King Fahd Hospital of the University physicians. Physicians noted that cultural standards and religious beliefs do play a role in their decision-making but had less of an effect as compared to other clinical data such as comorbidities, age, and previous ICU admissions.

Global, Regional, and National Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life-Years for 29 Cancer Groups, 1990 to 2017: A Systematic Analysis for the Global Burden of Disease Study

Importance

Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data.

Objective

To describe cancer burden for 29 cancer groups in 195 countries from 1990 through 2017 to provide data needed for cancer control planning.

Evidence Review

We used the GBD study estimation methods to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs). Results are presented at the national level as well as by Socio-demographic Index (SDI), a composite indicator of income, educational attainment, and total fertility rate. We also analyzed the influence of the epidemiological vs the demographic transition on cancer incidence.

Findings

In 2017, there were 24.5 million incident cancer cases worldwide (16.8 million without nonmelanoma skin cancer [NMSC]) and 9.6 million cancer deaths. The majority of cancer DALYs came from years of life lost (97%), and only 3% came from years lived with disability. The odds of developing cancer were the lowest in the low SDI quintile (1 in 7) and the highest in the high SDI quintile (1 in 2) for both sexes. In 2017, the most common incident cancers in men were NMSC (4.3 million incident cases); tracheal, bronchus, and lung (TBL) cancer (1.5 million incident cases); and prostate cancer (1.3 million incident cases). The most common causes of cancer deaths and DALYs for men were TBL cancer (1.3 million deaths and 28.4 million DALYs), liver cancer (572 000 deaths and 15.2 million DALYs), and stomach cancer (542 000 deaths and 12.2 million DALYs). For women in 2017, the most common incident cancers were NMSC (3.3 million incident cases), breast cancer (1.9 million incident cases), and colorectal cancer (819 000 incident cases). The leading causes of cancer deaths and DALYs for women were breast cancer (601 000 deaths and 17.4 million DALYs), TBL cancer (596 000 deaths and 12.6 million DALYs), and colorectal cancer (414 000 deaths and 8.3 million DALYs).

Conclusions and Relevance

The national epidemiological profiles of cancer burden in the GBD study show large heterogeneities, which are a reflection of different exposures to risk factors, economic settings, lifestyles, and access to care and screening. The GBD study can be used by policy makers and other stakeholders to develop and improve national and local cancer control in order to achieve the global targets and improve equity in cancer care.

Uterine Transplant: A Risk to Life or a Chance for Life?

Being inherently different from any other lifesaving organ transplant, uterine transplantation does not aim at saving lives but supporting the possibility to generate life. Unlike the kidneys or the liver, the uterus is not specifically a vital organ. Given the non-lifesaving nature of this procedure, questions have been raised about its feasibility. The ethical dilemma revolves around whether it is worth placing two lives at risk related to surgery and immunosuppression, amongst others, to enable a woman with absolute uterine factor infertility to experience the presence of an organ enabling childbirth. In the year 2000, the first uterine transplantation, albeit unsuccessful, was performed in Saudi Arabia from where it has spread to the rest of the world including Sweden, the United States and now recently India. The procedure is, however, still in the preclinical stages and several ethical, legal, social and religious concerns are yet to be addressed before it can be integrated into the clinical setting as standard of care for women with absolute uterine factor infertility.

Sanitary Worker's Death Unnerves Pakistan's Health Care Ethics to the Core

Health care ethics is a sensitive domain, which if ignored, can lead to patient dissatisfaction, weakened doctor-patient interaction and episodes of violence. Little importance has been paid to medical ethics within undergraduate medical education in developing countries such as Pakistan. Three doctors in Pakistan are currently facing an official police complaint and arrest charges, following the death of a sanitary worker, who fell unconscious while cleaning a drain and was allegedly refused treatment as he was covered in sewage filth. The medical license of the doctors in question should be cancelled, if found guilty following a thorough investigation into the case. The 'right to life' has been universally assured by all moral, cultural and legal codes and no society can ever argue against the sacredness of a human life. It is quite clear that the aforesaid doctors' actions are not only against the core principles of the physicians' code, but also go against the doctrine of human rights. If serious efforts on an urgent basis are not made by the regulatory and governing bodies, one can definitely expect similar incidents for at least a few more decades before any noticeable change is seen.

Cerbera odollam toxicity: A review

Cerbera odollam is a plant species of the Apocynaceae family. It is often dubbed the 'suicide tree' due to its strong cardiotoxic effects, which make it a suitable means to attempt suicide. The plant grows in wet areas in South India, Madagascar, and Southeast Asia; and its common names include Pong-Pong and Othalanga. The poison rich part of the plant is the kernel which is present at the core of its fruit. The bioactive toxin in the plant is cerberin, which is a cardiac glycoside of the cardenolide class. Cerberin has a mechanism of action similar to digoxin; hence, Cerbera odollam toxicity manifests similar to acute digoxin poisoning. Ingestion of its kernel causes nausea, vomiting, hyperkalemia, thrombocytopenia, and ECG abnormalities. Exposure to high doses of Cerbera odollam carries the highest risk of mortality. Initial management includes supportive therapy and administration of atropine followed by temporary pacemaker insertion. Administration of digoxin immune Fab may be considered in severe cases, although efficacy is variable and data limited to isolated case reports.

Abortion of Fetus with Down's Syndrome: India Joins the Worldwide Controversy Surrounding Abortion Laws

Abortion continues to be a moral and ethical dilemma in medicine. While abortions in general have always faced social stigmas, the abortion of fetuses with Down's syndrome in particular remains the subject of debate across the globe. In India, under the Medical Termination of Pregnancy Act, abortion is legal under prescribed circumstances only till 20 weeks of gestation. Laws for abortion after 20 week of gestation are ill defined. In a recent ruling of the Supreme Court in India, a woman was denied the right to abortion of her 26 week old fetus. With this ruling, India has joined the rest of the world in the debate surrounding abortion laws and the ethics of abortion.

Gastrointestinal causes of sudden unexpected death: A review

Gastrointestinal conditions are a less common cause of sudden unexpected death when compared to other conditions such as cardiovascular conditions, but they are equally important. Various congenital and acquired gastrointestinal conditions that have resulted in sudden unexpected death are discussed. The possible lethal mechanisms behind each condition, along with any associated risk factors or secondary diseases, have been described. Through this article, we aim to highlight the need for physicians to prevent death in such conditions by ensuring that subclinical cases are diagnosed correctly before it is too late and by providing timely and efficacious treatment to the patient concerned. In addition, this review would certainly benefit the forensic pathologist while dealing with cases of sudden unexpected death due to gastrointestinal causes. This article is a review of the major gastrointestinal causes of sudden unexpected death. In addition, related fatal cases encountered occasionally in forensic autopsy practice are also included. There are several unusual and rare causes of life-threatening gastrointestinal bleeding that may lead to sudden unexpected death to cover all the entities in detail. Nevertheless, this article is a general guide to the topic of gastrointestinal causes of sudden unexpected death.

Breaking your heart-A review on CPR-related injuries

Cardiopulmonary resuscitation (CPR) has been shown to increase survival after cardiac arrest, but is associated with the risk of acquired injuries to the patient. While traumatic chest wall injuries are most common, other injuries include upper airway, pulmonary and intra-abdominal injuries. This review discusses the risk factors and prevalence of CPR-related injuries.

Personalized Medicine in a New Genomic Era: Ethical and Legal Aspects

The genome of two completely unrelated individuals is quite similar apart from minor variations called single nucleotide polymorphisms which contribute to the uniqueness of each and every person. These single nucleotide polymorphisms are of great interest clinically as they are useful in figuring out the susceptibility of certain individuals to particular diseases and for recognizing varied responses to pharmacological interventions. This gives rise to the idea of 'personalized medicine' as an exciting new therapeutic science in this genomic era. Personalized medicine suggests a unique treatment strategy based on an individual's genetic make-up. Its key principles revolve around applied pharmaco-genomics, pharmaco-kinetics and pharmaco-proteomics. Herein, the ethical and legal aspects of personalized medicine in a new genomic era are briefly addressed. The ultimate goal is to comprehensively recognize all relevant forms of genetic variation in each individual and be able to interpret this information in a clinically meaningful manner within the ambit of ethical and legal considerations. The authors of this article firmly believe that personalized medicine has the potential to revolutionize the current landscape of medicine as it makes its way into clinical practice.

Commotio cordis: A review

Commotio cordis is an increasingly reported fatal mechano-electric syndrome and is the second most common cause of sudden cardiac death in young athletes. It is most commonly associated with a sports-related injury, wherein, there is a high-velocity impact between a projectile and the precordium. By virtue of this impact, malignant arrhythmias consequently develop leading to the individual's immediate demise, accompanied by a relatively normal post-mortem analysis. The importance of an autopsy remains paramount to exclude other causes of sudden death. With increasing awareness and reporting, survival rates are beginning to improve; however, prevention of the development of this condition remains the best approach for survival.

Consented Autopsy and the Middle-East

Consented autopsy is almost non-existent in the Middle-East where established social and cultural beliefs regarding the procedure might discourage family members from requesting a consented autopsy. Evidence suggests that new information is obtained from consented autopsies. It would not be in the best interest of medicine if social and cultural misconceptions succeed in erasing the existence of consented autopsies entirely.

Post-mortem CT evaluation of atlanto-occipital dissociation

Atlanto-occipital dissociation injury is an important injury in forensic pathology practice. Radiological diagnosis of atlanto-occipital dissociation clinically is assessed by direct measurement of occipito-vertebral skeletal relationships. Different measurements may be used to diagnose atlanto-occipital dissociation, including the basion-dens interval (BDI) and basion-axial interval (BAI). It is not known whether the normal ante-mortem measurements of BDI and BAI described in the literature are applicable to post-mortem CT images of the occipito-cervical junction (OCJ) or whether these measurements could be affected by early post-mortem changes. This study aims to compare post-mortem BDI and BAI measurements with ante-mortem values. Post-mortem CT scans of the cervical spines of 100 deceased adults were reviewed, and the BDI and BAI were measured. Different parameters were recorded in each case. The results from this study suggest that there are no effects of post-mortem changes on the measurement of BAI as relied upon clinically. There appear to be some effects of fully established rigor mortis on BDI measurement, shortening it. This may have consequences for the post mortem diagnosis of atlanto-occipital dissociation.

Lobed spleen: an autopsy case report with emphasis on surgical anatomy

During the medico-legal autopsy of a male aged 45 years, a bilobed morphology of the spleen was observed. An oblique fissure was located longitudinally at the mid-region of the diaphragmatic surface of the spleen. The fissure was partially deep and observed throughout the diaphragmatic surface. The clinician should be aware of the developmental anomalies of the spleen; as such anomalies may cause confusion during the procedures like splenic biopsy and splenectomy. We believe that, the present case report is important to the radiologists and clinicians involved in the diagnosis and management of splenic pathology. The knowledge is also enlightening to the morphologists and embryologists. The radiologist and clinician should make sure that the fissure in a spleen is not misinterpreted as a laceration or rupture.

Authorship: Few Myths and Misconceptions

This article seeks to address and dispel some of the popular myths and misconceptions surrounding authorship of a scientific publication as this is often misconstrued by beginners in academia especially those in the developing world. While ethical issues in publishing related to authorship have been increasingly discussed, not much has been written about the myths and misconceptions of who might be an author. Dispelling these myths and misconceptions would go a long way in shaping the thoughts and plans of students, junior faculty and researchers in academia especially in the developing world.

Undergraduate teaching of forensic medicine in Saudi Arabia

Medico-legal tasks are not exclusive to forensic medical experts -any physician may face medico-legal issues in his career. Hence, the practice of medicine requires education in legal issues. In Saudi Arabia, there are 30 universities with medical colleges, but we do not know how they teach undergraduate forensic medicine and medico-legal issues. The aim of this study was to discover undergraduate training courses in forensic medicine in Saudi universities. We conducted a cross-sectional study involving all colleges of medicine in Saudi Arabia. A structured, self-administered questionnaire containing 13 items relating to the undergraduate forensic medicine course was distributed. Out of a total of 30 universities, 27 universities responded. Of these 27 universities, 16 (59.26%) teach forensic medicine to undergraduate medical students, and 11 (40.74%) do not teach forensic medicine in their undergraduate curriculum. Of the 27 universities that responded, none has a department of forensic medicine. Eleven universities that do not teach forensic medicine have no forensic medicine unit/division or faculty at all. Forensic medicine belongs to the pathology department in 11 universities, while it belongs to different departments in five universities. There is variation in teaching methods, years where the course is taught and length of the course. Practical and morgue visits take place in 7/16 (43.8%) universities, while 9/16 (56.3%) universities only teach the theoretical aspects of forensic medicine. All 16 universities teach forensic medicine only to medical students and do not teach it to students in other colleges such as dentistry and nursing.

Research at an Undergraduate Level - An Insight into its Importance

In the world of evidence-based medicine, the need for research cannot be overstated. While the helm of such research if being conducted by trained scientists in secluded labs, one often forgets that these scientists were students too at one point in time. If their interest was not honed then, we might still be fighting polio today. Thus with this editorial we hope to usher more students into research at the undergraduate level.

Chemical crowd control agents

Chemical crowd control agents are also referred to as riot control agents and are mainly used by civil authorities and government agencies to curtail civil disobedience gatherings or processions by large crowds. Common riot control agents used to disperse large numbers of individuals into smaller, less destructive, and more easily controllable numbers include chloroacetophenone, chlorobenzylidenemalononitrile, dibenzoxazepine, diphenylaminearsine, and oleoresin capsicum. In this paper, we discuss the emergency medical care needed by sufferers of acute chemical agent contamination and raise important issues concerning toxicology, safety and health.

Evaluation of the mastoid triangle for determining sexual dimorphism: A Saudi population based study

Demographic assessment of skeletal remains in forensic investigations includes identification of sex. The present study aimed to develop population-specific, sex-discriminating anthropometric standards for the mastoid triangle of a documented Saudi population using computed tomographic (CT) images of the lateral aspect of the skull. The present study was performed on 206 CT images of a documented Saudi population of known sex and age. The clinical CT images of subjects visiting the Department of Radiology, Dammam Medical Complex, Dammam, Saudi Arabia (KSA) were evaluated to know the validity of the metric assessment of the mastoid triangle for identification of sex in a Saudi population. The distance between asterion to porion (AP), asterion to mastoidale (AM), porion to mastoidale (PM) were measured and the area of the mastoid triangle (AMT) was calculated using these measurements. Discriminant function procedure was used to analyze the data for sexual dimorphism. In conclusion, the results of the present study indicate that all the 3 sides of the mastoid triangle and AMT were sexually dimorphic in the sampled Saudi population with PM being the best individual parameter in discriminating sex with an accuracy of 69.4%. Whereas, all the parameters combined showed the highest accuracy (71.4%).

Publication ethics

High-quality scientific literature is the cornerstone of scientific progress and is highly regarded by academia. However, scientific literature is often marred by plagiarism, data fabrication and falsification, redundant publication and illegitimate authorship. These problems are discussed in this article.
