Epidemiology of Burns in Rural Bangladesh: An Update

Trends in disease characteristics and premature mortality among hospitalised middle-aged patients in Anhui Southern Area, China, between 2011 and 2020: a cross-sectional study

OBJECTIVES

We aimed to explore the characteristics of age, disease and premature mortality among middle-aged inpatients.

DESIGN

Cross-sectional.

SETTING

Data were gathered from the electronic medical records system of the hospitals between 2011 and 2020: a regional study.

PARTICIPANTS

A total of 151 320 patients, aged 45-59 years, underwent hospitalisation.

PRIMARY OUTCOME MEASURES

We analysed the characteristics of age and disease using the database from the electronic medical record system. Moreover, a binary logistic regression model was adopted to investigate the risk factors for premature mortality.

RESULTS

We identified 151 320 eligible inpatients, 53.0% of whom were female. The proportion of middle-aged inpatients increased alarmingly over a decade from 6.4% in 2011 to 28.3% in 2020. The incidence rate of inpatients aged 45 to 50 years increased perpendicularly, with its peak observed at the age of 50. The prevalence tended to decrease after the age of 50; however, it increased at the age of 59. Overall, cancer had the highest incidence rate (22.7%), followed by accidental injury, digestive system disease, cardiovascular disease and cerebrovascular disease (9.0%, 7.9%, 6.3% and 4.5%, respectively). The overall mortality among the middle-aged inpatients was 0.5%. Logistic regression analysis showed that sex, marital status and comorbidity were the factors contributing to mortality in hospitalised patients, with male, divorced and more than two comorbidities being risk factors for death.

CONCLUSIONS

A rising trend in the number of middle-aged inpatients was observed during the study period. The number of hospitalisations reaches its peak at the age of 50. Being male, divorced and having more than two comorbidities are risk factors for premature mortality. So prevention, early detection and appropriate treatment of comorbidities are beneficial in improving health and reducing mortality.

Burn injuries and acute burn management in the rural areas in northern Bangladesh - A household survey

INTRODUCTION

Burn injuries pose a significant public health challenge, especially in low- and middle-income countries (LMICs). In Bangladesh, burn injuries are prevalent and often result in severe disability or death. However, knowledge regarding the causes of burn injuries, acute burn management, and barriers to seeking burn care in the riverine areas of northern Bangladesh is limited.

METHODS

We conducted a questionnaire-based study in eight subunits and five selected districts in northern Bangladesh to determine the prevalence, causes, and management of burn injuries in these areas. A total of 210 individuals from different households were interviewed, which represented a population of 1020 persons.

RESULTS

Among the respondents, 55% reported that at least one member of their household suffered from a burn injury in the past. The most common causes of burn injuries were open fire (41%) and hot fluids (30%). More than 40% of burns were not rinsed with water directly after sustaining the injury. Additionally, almost 30% of respondents did not seek medical care immediately after the injury, with financial constraints being the most commonly cited reason.

DISCUSSION

We found a low rate of adequate cooling and seeking medical care. The need for basic knowledge on prevention and treatment of burn injuries and improved access to affordable health care services in the region is high.

The Perceived Informational Needs of Family Caregivers of Children Hospitalized in a Burn Department: A Cross-sectional Study

Children are most vulnerable to burn injuries, and their families are their most important source of support. Therefore, it is necessary to identify the information needs of such parents and support them to help children adapt to the new situation, recover to pre-accident conditions, and reintegrate into school and society. This study aimed to investigate the perceived information needs of family caregivers of children admitted to the burn wards of hospitals. This cross-sectional study was conducted on 200 family caregivers of children admitted to the burn ward of a hospital in Tabriz, Iran. Participants were selected through convenience sampling, and the required data were collected by using questionnaires on socio-demographic information, information needs, information resources, and information acquisition methods. The obtained data were analyzed statistically using descriptive statistics (mean, standard deviation, frequency, and percentage) and inferential statistics (Mann-Whitney, Kruskal-Wallis, and Spearman correlation tests). Results indicated that the greatest informational need among family caregivers was related to the child's condition. The treatment team was identified as the most important source of information for them. It was found that information should be provided in a comprehensive and understandable manner, while maintaining honesty and human dignity. The study findings contribute to our understanding of the specific information needs of family caregivers in managing the medical care of children with burns. These findings can serve as a basis for interventions and support services aimed at meeting the needs of these families and improving the quality of care for children with burns.

Food Security as a Predictor of Global Pediatric Postburn Mortality

Food security (FS) is defined as access to sufficient and nutritious food. Children, especially those in low- and middle- income countries (LMICs), are disproportionately affected by low FS. We hypothesized high FS would be predictive of decreased pediatric postburn mortality in LMICs. Publicly-available, deidentified datasets were obtained from the World Health Organization's Global Burn Registry (GBR) and Economist Intelligence Unit's Global FS Index (GFSI). The GFSI calculates FS scores annually from intergovernmental organization data reviewed by a panel of experts. FS scores are reported on a 0 to 100 scale with 100 indicating the highest FS. Patients aged 0 to 19 yr were included; after linking GBR and GFSI datasets, countries with <100 burn patients were excluded. Data were analyzed with descriptive statistics and bivariate analyses. Multiple logistic regression controlling for confounders was used to quantify associations between mortality and FS score. Significance was set at P < 0.05. From 2016 to 2020, there were 2,246 cases including 259 deaths (11.5%) over nine countries. Those who died had a higher median age (7 [IQR 2, 15] vs 3 [2, 6] years, P < 0.001), higher proportion of females (48.6% vs 42.0%, P =0.048), and lower median FS score (55.7 [IQR 45.3, 58.2] vs 59.8 [IQR 46.7, 65.7], P < 0.001). Increasing FS score was associated with decreased odds of postburn mortality [multivariable odds ratio 0.78 (95% confidence interval 0.73 to 0.83), P < 0.001]. With the association between FS and mortality, international efforts to increase FS in LMICs may help improve pediatric burn patient survival.

A Review of Petrol Burns in Australia and New Zealand

Petrol-related thermal burns cause significant morbidity and mortality worldwide and it has been established that they affect young males disproportionately. Beyond this, we sought to identify the difference in the characteristics and outcomes of burns between males and females in an international population. Such differences may highlight areas for future preventative strategies. The Burns Registry of Australia and New Zealand was used. Petrol burns that resulted in a hospital admission in those 16 years or older between January 2010 and December 2019 were included. A total of 2833 patients were included. The median age was 35 years with most patients being male (88%). Burns from a campfire or burnoffs were most common. Females were more likely to suffer burns due to assault or from deliberate self-harm. The total body surface area affected by burns was higher for females than males (10% vs 8%). Furthermore, females more frequently required ICU admission, escharotomies, and had a longer hospital length of stay. The unadjusted mortality rate for females was more than double the rate for males (5.8% vs 2.3%). This international study demonstrates that whilst men more frequently suffer petrol burns, women suffer more severe burns, require more intensive and longer hospitalizations and have a higher mortality rate. These findings may inform changes in preventative health policies globally to mitigate against these concerning findings.

Nosocomial Infection Among Burn Patients Admitted to a Tertiary Care Hospital of Bangladesh: A Cross-Sectional Study

Nosocomial infection is a major challenge for the appropriate management of burns. The present study aimed to investigate incidence, risk factors, and causative organisms of nosocomial infection in burn patients of Khulna, Bangladesh. This cross-sectional study was conducted among patients admitted to the Burn and Plastic Surgery Department of Khulna Medical College Hospital (KMCH) from January to December 2020. Relevant data were collected from the patients' hospital records. Samples of wound swabs and blood were collected and cultured in the microbiology laboratory of KMCH. Logistic regression models were used to determine risk factors for infective complications in burn patients. All statistical analyses were carried out using SPSS version 26.0. A total of 100 burn patients were included. Mean age was 29.2 years with a male-female ratio of 1.3:1. Flame burns were most prevalent among the patients (41%), followed by scald (23%) and electric burns (15%). Almost 40% patients had full thickness burn. The incidence of nosocomial infection was 42% (wound infection 33% and septicemia 9%). Total body surface area of burn >40% (OR 7.56, 95% CI 2.89-19.81), full thickness burn (OR 34.40, 95% CI 3.25-97.14) and prolonged hospital stay (aOR 1.31, 95% CI 1.15-1.51) were significant risk factors for nosocomial infection. Staphylococcus aureus was the most commonly isolated organism (45%), followed by Streptococcus (24%), Pseudomonas aeruginosa (19%) and Escherichia coli (12%). As the epidemiology of nosocomial infection is not the same in different health facilities, a facility-based comprehensive burn management protocol considering the local epidemiology and causative organisms of burn wound infection is crucial for the prevention and management of nosocomial infections in burn patients.

Behavioural and environmental risk factors for household injuries: semistructured interviews with health professionals and mothers in Iran

BACKGROUND

Injuries are increasing global public health problems, causing disability and death among children. This has considerable financial, emotional and social effects on families and society. This study aimed to investigate the behavioural and environmental factors leading to unintentional home injuries and attempts to highlight the pivotal role of mothers' behaviour and performance to provide a safe place for children at home.

METHODS

The current research is a qualitative study of a directed content analysis type. The data were gathered through semistructured interviews conducted in participants' workplaces, namely universities, research centres and health centres. In some cases, telephone interviews were conducted within 3 months, from February 2021 to May 2021 in Tehran, Iran. The participants were selected through non-probability and purposive sampling. All the recorded interviews and notes were accurately evaluated, and data analysis was performed based on the content analysis. There were 29 interviews in total: 12 interviews with mothers, 9 with treatment and prevention specialists, and 8 with researchers.

RESULTS

A total of 66 factors, 6 subcategories and 2 main categories were extracted after analysing the interviews. The main categories included environmental and behavioural factors. The subcategories included house infrastructure, house equipment/furniture, children's equipment/furniture, provision of precarious conditions, access to hazardous substances and appliances, and unsafe arrangement of furniture.

CONCLUSION

Despite the existing obstacles such as the long-term implementation, financial difficulties and overcomplicated policy-making process, health interventions can make it possible for mothers of children under the age of seven to adopt preventive measures through appropriately designed instructions and optimal use of existing facilities.

Fire burns matter: A case-control study of severe accidental burns in pediatric patients

<b>Objective: </b>We aimed to identify factors associated with severe accidental burns in patients ≤12 years old.<br /> <b>Materials and methods: </b>We conducted a matched case-control study, in which we retrospectively reviewed the medical records of children treated in a single institution from 2014-2016. We classified the cases (patients with severe burns) and controls (patients with non-severe burns) according to the criteria of the American Burn Association. We used multivariate conditional logistic regression analysis to identify the relationship between the etiology of burns and their severity.<br /> <b>Results: </b>We reviewed 180 cases and 90 controls. The most common etiology of burns was boiling water in both cases (65.6%) and controls (83.3%). Most burns occurred inside the home (84.1%) and in the afternoon (37.4%). Multivariate analysis identified that severe burns were mainly due to exposure to fire (odds ratio [OR]: 3.22, 95% confidence interval [CI]: 1.53-6.81). Similarly, these patients were more likely to live in a rural area (OR: 2.96, 95% CI: 1.17-6.19).<br /> <b>Conclusions: </b>In pediatric patients ≤12 years of age severe accidental burns are more likely to be caused by fire compared to boiling water. Public health interventions should focus on populations located in rural areas.

Pediatric First-Degree Burn Management With Honey and 1% Silver Sulfadiazine (Ag-SD): Comparison and Contrast

Background The cardinal area of managing fire wounds is guided by adequately evaluating the burn-induced lesion's profundity and size. Superficial second-degree burns are often treated through daily reinstating with fresh sterile bandaging with appropriate topical antimicrobials to allow rapid spontaneous epithelialization. Around the world, a wide variety of substances are used to treat these wounds, from honey to synthetic biological dressings. Objective This study intended to determine honey's therapeutic potential compared with 1% silver sulfadiazine (Ag-SD) in arsenal-caused contusion medicament fulfillment. Methods A total of 70 cases were evaluated in this research work after fulfilling the required selection criteria during the study period of January 2014 to December 2014 and January 2017 to December 2017. Purposive selection criteria were adopted in the study to select research patients. The patients in Group-1 (n = 35) relied on honey as medication, while patients in Group-2 (n = 35) relied on 1% Ag-SD. Results In Group-1, exudation (68.4%) and sloughing (82.9%) were substantially reduced by Days 3 and 5 of therapeutic intervention, respectively. However, in Group-2, a reduction of exudation (17.1%) and sloughing (22.9%) occurred after Days 3 and 5 of treatment, respectively. Completion of the epithelialization process was observed among Group-1 and Group-2 cases. It was detected after Days 7 and 10 of treatment at 36.3% and 77% (Group-1) and 27% and 67% (Group-2), respectively. Around 3 ml of 1% honey was required per body surface area per dressing in Group-1. On the other hand, in Group-2, 2 gm Ag-SD was needed per body surface area per dressing. Conclusion Patients treated with honey found better clinical outcomes in managing superficial partial-thickness burns.

Epidemiology of non-fatal burn injuries in children: evidence from Bangladesh Health and Injury Survey 2016

BACKGROUND

Burn is a major cause of childhood injury-related morbidity and mortality. Global estimates suggest that 90% of all cases occur in low-income and middle-income countries and over half of the disability-adjusted life-years are lost from fire-related burns in children. In Bangladesh, there is a scarcity of data on childhood burn injuries. The goal of the study was to describe the epidemiology of non-fatal burns in Bangladeshi children, including incidence estimates and identify high-risk groups.

METHODS

Bangladesh Health and Injury Survey 2016 was a large scale cross-sectional survey. The survey was conducted among 299 216 population utilising a multistage cluster sampling method. Among the 100 842 children, there were 437 non-fatal burn cases.

RESULTS

Among different injury mechanisms in children, burn was ranked fifth (7.4%). The overall yearly incidence rate (IR) of burns was 866.7 per 100 000 children (95% CI 785.6 to 947.8) in Bangladesh. The incidence was highest among 1-4 years old children (IR 2028.3, 95% CI 1761.1 to 2334.7) and had a 3.5 times higher risk of burns compared with the 15-17 years age group. Females had a much higher IR of non-fatal burns than males between the ages of 10-15 years (1655.2 vs 482.2). About 70% of burns occurred in rural areas. Hot liquid (44.7%), flames (32.5%) and hot objects (20.7%) were identified as the main causes of burns. The kitchen (60.9%), yards (20.8%) and bedroom and living room (10.5%) were the three most common places for burns. According to the study, 34.8% of burn incidences occurred between the hours of 7:00 and 10:00.

CONCLUSION

Children in Bangladesh suffer from a high rate of non-fatal burns. The high-risk category was identified as preschool-aged boys and adolescent girls. The majority of the incidents occurred in the morning and inside the kitchen. These findings will help raise awareness and create intervention measures to reduce the high incidence of non-fatal childhood burns in Bangladesh.

Evaluation of patterns, cause and risk factors of burns in patients with seizure

BACKGROUND

Burns following convulsion could be an important problem for patients with epilepsy. In the present study we aimed to identify the pattern and the cause of burns in these patients.

METHODS

This is a cross-sectional study that was performed in 2017-2019 in Guilan on 40 patients with burns following seizure. The information in the records of patients were reviewed. We collected data including age, sex, marital status, occupation, place of residence, length of hospital stay, anatomy of the burn site, percentage of burn, degree of burns, cause of burns and disease outcome.

RESULTS

The mean age of the patients was 42.2±2.99 years. Seven cases (17.5%) had burns due to fire, 5 cases (12.5%) due to gas explosion, 3 cases (7.5%) due to electrocution, 15 cases (37.5%) with hot water, 1 case (2.5%) with hot liquids, 5 cases (12.5%) with hot surface, 1 case (2.5%) with hot bath, 2 cases (5%) with hot food and 1 case (2.5%) with hot glue. The mean burning percentage of patients was 19.3±3.18%. The most common patterns of burns were observed as 7 (17.5%) upper limbs and 7 (17.5%) lower limbs. The mean duration of hospitalization was 5.05±0.69 days ranging from 1 to 18 days. 37 patients (92.5%) recovered partially and 3 patients (7.5%) died.

CONCLUSION

Hot water, fire and hot surface are most common causes of burns and there were significant direct correlations between age with percentage of burns and duration of hospitalization. We believe further studies should evaluate the preventive strategies in this regard.

Tolerance to Glucose and Lipid High Metabolic Reactions After Burns in an Obese Rat Model

The goal of this study was to determine what effect obese body weight and a burn injury can have on the metabolism of glucose and lipids in rats. We used a 3 * 3 factorial model design to provide basic glucose and lipid metabolic data characterizing the interaction between different weight and burn injury groups. Two hundred Sprague Dawley rats were categorized into three weight groups (normal, overweight, obese) and then further divided into control, second-degree, and third-degree burn groups. Our model compared interactions between weight and burn injury factors according to the above groups. Blood glucose and lipid metabolism indicators were monitored on the 1st, 3rd, 7th, and 14th days after burn injury occurred, and burned skin and blood samples were collected for testing. Compared with the normal weight group, the overweight group's fast blood glucose, fast insulin, and homeostasis model assessment of insulin resistance were higher (P < .05), and FBG in the obese group was higher than the normal weight group (P < .05). Burn injuries combined with obese body weight had an interactive effect on fast blood glucose, fast insulin, and homeostasis model assessment of insulin resistance after burn injury (P < .05). Burn injury combined with obese body weight had an interaction on low-density lipoprotein cholesterol on the 3rd day after burn injury (P < .05). Burn injury combined with obese weight had no interaction on triglyceride, total cholesterol, and high-density lipoprotein cholesterol (P > .05). Rats in the overweight and obese weight groups were observed to develop an adaptation and tolerance to a higher metabolic rate after burn injuries occurred.

Exploration of Potential Molecular Targets of Dexmedetomidine in the Intestinal Repair of Burnt Rats

Background

More and more burn survivors were suffering from varying degrees of damage to the intestinal barrier. Dexmedetomidine (Dex) was frequently used as sedative in more cases, but it was found to have repair effect on intestinal barrier dysfunction recently. This study aimed to explore the potential specific targets of Dex in intestinal barrier repair in burn rats model.

Methods

Male adult SD rats were used to establish 40% TBSA III degree scald model in our study. The samples were divided into four groups: burn rats (Burn), burn rats with Dex medication (Burn-Dex), sham rats (Sham) and sham rats with Dex medication (Sham-Dex). And plasma FITC-dextran and diamine oxidase (DAO) were detected to determine the intestinal permeability. Differentially expressed proteins were further adopted to protein-protein interaction network analysis, Gene Ontology analysis (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis.

Results

It showed that 40% TBSA III degree scald model was successfully constructed. And plasma FITC-dextran and DAO decreased significantly after Dex administration. Additionally, differentially expressed genes Psmb10, Psmb7 among the experimental groups were screened, which were significantly enriched in proteasome and other several pathways.

Conclusion

The results above suggested that Q4KM35 and Q9JHW0, which are encoded by Psmb10 and Psmb7, respectively, are two possible protein targets of Dex in intestinal barrier repair.

Global Burn Registry Perspective on Head and Neck Burns

INTRODUCTION

As exposed regions of the body, the head and neck are at increased risk of burn injury. The cosmetic and functional importance of these anatomical regions means that burns can result in substantial morbidity and mortality. Our objective was to characterize predictive factors for surgery and discharge condition in patients with head and neck burns internationally.

METHODS

We conducted an epidemiological study of all head and neck burns in 14 countries reported in the World Health Organization Global Burn Registry. Multivariate regression was used to identify variables predictive of surgical treatment and discharge condition.

RESULTS

We identified 1014 patients who sustained head and neck burns; the majority were adults (60%). Both adults and children admitted to hospital with head and neck burn injuries were less likely to be treated surgically in lower-middle-income countries (LMIC) than in higher-income countries (P < 0.001). Increasing age and greater total surface body area (TBSA) were significant predictors of surgical intervention in children with head and neck burn injuries (P < 0.001). Total surface body area, associated injuries, ocular burns, female sex, and LMIC residency were all significant predictors of mortality in adult patients with head and neck burns (P < 0.050). Conversely, TBSA was the only variable that independently increased the risk of death in children with head and neck burns (P < 0.001).

CONCLUSIONS

Certain groups are at increased risk of an adverse outcome after admission with a head and neck burn injury. Given the reduced incidence of surgical intervention and the elevated mortality risk in LMICs, global health initiatives should be targeted to these countries.

Perceptions of injury risk in the home and workplace in Nepal: a qualitative study

OBJECTIVE

Injuries are a global health problem. To develop context-specific injury prevention interventions, one needs to understand population perceptions of home and workplace injuries. This study explored a range of views and perceptions about injuries in a variety of settings and identified barriers and facilitators to injury prevention.

DESIGN

Qualitative study: interviews and focus groups.

SETTING

Three administrative areas: Hetauda submetropolitan city, Thaha municipality and Bakaiya rural municipality in Makwanpur, Nepal.

PARTICIPANTS

Nine focus groups (74 participants) and nine one-to-one interviews were completed; workers from diverse occupations, residents (slum, traditional or modern homes) and local government decision-makers participated in the study between May and August 2019. The interviews and discussions were audio-recorded, transcribed verbatim, translated to English and analysed thematically.

RESULTS

Six themes were developed: unsafe home and workplace environment; inadequate supervision and monitoring; perceptions that injuries are inevitable; safety takes low priority: financial and behavioural considerations; safety education and training; and government-led safety programmes and enforcement. Key barriers to injury prevention were perceived to be lack of knowledge about injury risk and preventive measures both at the community level and at the workplace. Facilitators were community-level educational programmes and health and safety training to employees and employers. Participants stressed the importance of the role of the government in planning future injury prevention programmes in different environments.

CONCLUSIONS

This study highlighted that both home and workplace injuries are complex and multifactorial. Lack of knowledge about injury risks and preventive measures, both at the community level and at the workplace, was found to be a common barrier to injury prevention, perceived to be mitigated by educational programmes. Together with previously published epidemiological evidence, the barriers and facilitators identified in this study offer useful basis to inform policy and practice.

Animal-related injuries and fatalities: evidence from a large-scale population-based cross-sectional survey in rural Bangladesh

OBJECTIVE

This study determines the magnitude and pattern of animal-related injury mortalities and morbidities in rural Bangladesh.

DESIGN AND SETTING

A cross-sectional survey was conducted in 51 Unions of 7 subdistricts of Bangladesh from June 2013 to September 2013.

PARTICIPANTS

A total of approximately 1.17 million individuals across all age and gender profiles were included in the survey. The participants had to be residents of the seven subdistricts and have provided consent to participate in the study.

PRIMARY AND SECONDARY OUTCOME MEASURES

Animal-related injury characteristics and demographic information was collected in the study. Frequency, proportion and 95% CIs of variables such as type of animal, type of animal attack, activity of the person prior to attack and the seasonality of the injury were reported. Data was then statistically analysed for associations between injury and sociodemographic characteristics.

RESULTS

The incidence rate of fatal and non-fatal animal-related injuries across all ages were 0.7 (95% CI 0.4 to 1.4) and 1635.3 (95% CI 1612.0 to 1658.0) per 100 000 populations, respectively. Non-fatal animal-related injury rates were highest among adults 18 years and older (1820.6 per 100 000 population (1777.2 to 1865.1)), and in males across all age groups. The most common animal injury was wasp/hornet/bee sting (49%), followed by cow/buffalo (25%), dog bite (9%) and snake bites (9%).

CONCLUSIONS

Animal-related injuries are an important public health issue in rural Bangladesh. The incidence of animal-related morbidities was found high in the study area. Males, school-going and productive age groups were at high risk. Immediate attention should be given to prevent these events.

Burden of Lesser-Known Unintentional Non-Fatal Injuries in Rural Bangladesh: Findings from a Large-Scale Population-Based Study

Around 90% of all fatal and non-fatal unintentional injuries occur in low- and middle-income countries (LMICs). The magnitude of unintentional injuries is unclear due to limited research and data. This paper describes the burden of lesser-known injuries (LKIs-cut injuries, unintentional poisoning, machine injuries, electrocution, injury by blunt objects, and suffocation) in rural Bangladesh, using data from the Saving of Lives from Drowning (SoLiD) project in Bangladesh. Descriptive statistics were used to report counts and rates of injuries by socio-demographic factors, injury characteristics, and circumstantial details. The annual morbidity rate of LKIs was 6878 injuries per 100,000 persons, involving 3.4% (40,520) of the population. Cut injury (44,131.2/100,000 per year) and injury by blunt objects (19768.6/100,000 per year) attributed in large numbers to the overall burden of LKIs. Males (66.1%) suffered more injuries than females. More than half (52.9%) occurred among people aged 25 to 64 years. Those involved in agriculture suffered the most injuries, mainly cut injuries (9234.1/100,000 per year) and machine-related injuries (582.9/100,000 per year). Most injuries occurred in the home setting. Increased awareness about packaging, storage, and the proper handling of appliances can help lower the frequency of LKIs. Safe architecture and awareness about home injuries is required to reduce injuries occurring in the home environment.

Characterization of burn wound healing gel prepared from human amniotic membrane and Aloe vera extract

Background

Skin burn wound is a notable medical burden worldwide. Rapid and effective treatment of burnt skin is vital to fasten wound closure and healing properly. Amniotic graft and Aloe vera are widely used as wound managing biomaterials. Sophisticated processing, high cost, availability, and the requirement of medics for transplantation limit the application of amnion grafts. We aim to prepare a novel gel from amnion combined with the Aloe vera extract for burn wound healing which overcome the limitations of graft.

Methods

Two percent human amniotic membrane (AM), Aloe vera (AV) and AM+AV gels were prepared. In vitro cytotoxicity, biocompatibility, cell attachment, proliferation, wound healing scratch assays were performed in presence of the distinct gels. After skin irritation study, second-degree burns were induced on dorsal region of Wistar rats; and gels were applied to observe the healing potential in vivo. Besides, macroscopical measurement of wound contraction and re-epithelialization; gel treated skin was histologically investigated by Hematoxylin and eosin (H&E) staining. Finally, quantitative assessment of angiogenesis, inflammation, and epithelialization was done.

Results

The gels were tested to be non-cytotoxic to nauplii and compatible with human blood and skin cells. Media containing 500 μg/mL AM+AV gel were observed to promote HaCaT and HFF1 cells attachment and proliferation. In vitro scratch assay demonstrated that AM+AV significantly accelerated wound closure through migration of HaCaT cells. No erythema and edema were observed in skin irritation experiments confirming the applicability of the gels. AV and AM+AV groups showed significantly accelerated wound closure through re-epithelialization and wound contraction with P < 0.01. Macroscopically, AM and AM+AV treated wound recovery rates were 87 and 90% respectively with P < 0.05. Histology analysis revealed significant epitheliazation and angiogenesis in AM+AV treated rats compared to control (P < 0.05). AM+AV treated wounds had thicker regenerated epidermis, increased number of blood vessels, and greater number of proliferating keratinocytes within the epidermis.

Conclusion

We demonstrated that a gel consisting of a combination of amnion and Aloe vera extract has high efficacy as a burn wound healing product. Amniotic membrane combined with the carrier Aloe vera in gel format is easy to produce and to apply.

Epidemiological, demographic and outcomes of burns among females at reproductive age in Baghdad/Iraq

BACKGROUND

Burns remained a major health problem in most developing countries which have increased the mortality and morbidity among the people. This study aimed to describe the epidemiology and outcomes of burn among females at reproductive age and investigate the factors that associated with mortality during the study period in in Baghdad/Iraq.

METHODS

A retrospective cohort study was undertaken at Al-Karama academic Hospital in Baghdad. Four hundred and thirty-seven females were admitted to this center from 1st of January 2017 to the end of October 2018. Data were collected from the records and patient file at the department of statistics. The information was including the age, education, marital status, occupation, TBSA, degree of burn, length of stay in hospital, causes, and patient condition. Software of STATA version 13 was used to analysis this data.

RESULTS

The mean age was 27.1 and SD 0.34 with 95% CI (26.4358 to 27.8067). the fire 64.8% (283/437) were the most cause of burn among females. Housewives 65% (284/437) were more probably exposed to burn than others with the mechanism of burning and females with primary education 42.8% (187/437) were more probability of burn than others group. Regard to length of stay, the mean was 7 days and the 95% CI [6.489-7.629]. Thus, 79.2% (346/437) of females that stayed in the hospital for less than 10 days had higher percentage of burn comparing with another period. Mean and SE of TBSA was 57.8 and 1.2 with the 95% CI [55.4051-60.2516]. A significant relationship was found between occupation, education status, TBSA, length of stay, causes of burn and outcomes at the p. value <0.05. The time at risk was 3085 with the incidence rate. 14. The survivor function in one day (Kaplan Meier estimate) was 0.8970 and SE 0.0144 with 95% CI [0.8645-0.9221].

CONCLUSION

The patients at age 26-45 years have equal hazard ratio of death (HR=1) at all the times of follow-upping. There is not statistically significant have been found at the (p. value =0.486), the 95% CI for the HR includes the null value of 1. As well the causes of burn, the patients with fire cause have a higher hazard of death HR=1.1 with the (p. value =0.012). Half of cases were single. A significant relationship has been found between the marital status and the age groups of the p. value 0.000. Also, a significant result of the intent status with causes of burn at the p. value 0.000.

Ethanol and Methanol Burn Risks in the Home Environment

Biofuel heaters and fireplaces have in recent years been introduced for indoor and outdoor use. Due to their simplicity, they are usually equipped with few or no safety features. Worldwide, incidents resulting in major skin burn injury and long hospitalization periods have occurred when using such biofuel units. The present study analyses the characteristics of the liquids ethanol and methanol to get a scientific background for understanding related accidents. The comparably heavy vapors, especially from ethanol, may generate a pillow of combustible gas in the vicinity of the unit, particularly in quiescent indoor air conditions. It is also revealed that these fuels represent a potential severe risk, since the equilibrium vapor pressures are close to the stoichiometric fuel–air composition at normal room temperatures. Selected incidents were reviewed to understand the mechanisms involved when severe burns were received by the users. It turns out that the most severe incidents were related to refilling operations and included ignition of the fuel container vapor phase. When ignited, the container gas phase expansion propelled burning fuel from the bottle or container onto the user or other persons in the vicinity. Similar incidents involving refilling methanol for chemistry demonstrations and ethanol for endodontic (dentistry) treatment were also studied and it was shown that these accidents followed similar accident mechanisms. It may be concluded that the main contributors to burn risk are the near-stoichiometric vapor pressure of these liquids at room temperature and the close proximity of the fuel container to burning fuel. Research needs and possible technical barriers are suggested to reduce this risk for the future.

Exploring perceptions of common practices immediately following burn injuries in rural communities of Bangladesh

Background

Burns can be the most devastating injuries in the world, they constitute a global public health problem and cause widespread public health concern. Every year in Bangladesh more than 365,000 people are injured by electrical, thermal and other causes of burn injuries. Among them 27,000 need hospital admission and over 5600 people die. Immediate treatment and medication has been found to be significant in the success of recovering from a burn. However, common practices used in the treatment of burn injuries in the community is not well documented in Bangladesh. This study was designed to explore the perception of local communities in Bangladesh the common practices used and health-seeking behaviors sought immediately after a burn injury has occurred.

Methods

A qualitative study was conducted using Focus Group Discussions (FGD) as the data collection method. Six unions of three districts in rural Bangladesh were randomly selected and FGDs were conducted in these districts with six burn survivors and their relatives and neighbours. Data were analyzed manually, codes were identified and the grouped into themes.

Results

The participants stated that burn injuries are common during the winter in Bangladesh. Inhabitants in the rural areas said that it was common practice, and correct, to apply the following to the injured area immediately after a burn: egg albumin, salty water, toothpaste, kerosene, coconut oil, cow dung or soil. Some also believed that applying water is harmful to a burn injury. Most participants did not know about any referral system for burn patients. They expressed their dissatisfaction about the lack of available health service facilities at the recommended health care centers at both the district level and above.

Conclusions

In rural Bangladesh, the current first-aid practices for burn injuries are incorrect; there is a widely held belief that using water on burns is harmful.

Modeling Skin Injury from Hot Rice Porridge Spills

The present work analyzes skin burns from spills of hot rice and milk products. The traditional Norwegian rice porridge serves as an example. By testing spills on objects emulating an arm, it was concluded that spills were seldom thinner than 3 mm, and stayed in place due to the viscosity of the porridge for more than one minute. The Pennes bioheat equation was solved numerically for such spills, including heat conduction to the skin and convective heat losses from the porridge surface. Temperatures were analyzed in the porridge and skin layers, and the resulting skin injury was calculated based on the basal layer temperature. Parameters influencing burn severity, such as porridge layer thickness, porridge temperature, removal of the porridge and thermal effects of post scald tempered (15 °C) water cooling were analyzed. The spilled porridge resulted in a prolonged heat supply to the skin, and the skin injury developed significantly with time. The porridge temperature turned out to be the most important injury parameter. A 70 °C porridge temperature could develop superficial partial-thickness burns. Porridge temperatures at processing temperatures nearly instantly developed severe burns. It was demonstrated that prompt removal of the hot porridge significantly reduced the injury development. The general advice is to avoid serving porridge and similar products at temperatures above 65 °C and, if spilled on the skin, to remove it quickly. After such scald incidents, it is advised to cool the injured area by tempered water for a prolonged period to stimulate healing.

Childhood injuries in Oman: retrospective review of a multicentre trauma registry data

OBJECTIVES

Injuries are among the top causes of hospital-based mortality for adults in Oman. However, little is known about the distribution and risk of injuries among children. This paper describes the epidemiology and risk factors for childhood injuries (0-15 years of age), in two hospitals of Oman.

METHODS

Data were collected between November 2014 and April 2015 at Khoula and Nizwa Hospitals. All patients between 0 and 15 years with a diagnosis of injury/trauma admitted to the hospital, and those who had trauma team activation in the emergency department were included in the analysis. Descriptive and multivariable Poisson regression analyses were conducted to generate sociodemographic risk factor profiles associated with the need for surgical management of injuries.

RESULTS

Out of 795 cases, 59% were under 5 years of age; 67% were males. Around 50% injuries were fall related, followed by exposure to inanimate mechanical forces and transport injuries. Burn injuries were more prevalent in females than males. Three-fourths of all injuries occurred in private residences. Almost 92% injuries were minor (Injury Severity Score <9). Of children with all types of injuries, 303 (40.9%) received surgical treatment. Patients suffering from head injuries (RR 8.8: 95% CI 4.9 to 15.3) or being involved in a burn injury (RR 1.5: 95% CI 0.3 to 7.5) were at increased risk of undergoing surgical treatment.

CONCLUSION

In this study, >30% of injury admissions were children 0-15 years of age. The high incidence of falls, home injuries and burns highlight the need for age-targeted interventions and injury control programmes. Although infrequent, transport injuries and head injuries put children in need of surgical management and prolonged hospital care.

Modeling Skin Injury from Hot Spills on Clothing

The present work analyzes scald burns from hot beverages, such as coffee and tea, spilled on the lap, i.e., an incident that may occur in daily life. The Pennes bioheat equation is solved numerically for small spills wetting the clothing, i.e., the fabric prevents the spilled liquid from draining away. Temperatures are analyzed in the wetted fabric and the skin layers and the resulting skin injury is calculated based on the basal layer temperature. Parameters influencing burn severity, such as clothing thickness, liquid temperature, removal of fabric and thermal effects of post scald water cooling are analyzed. The fabric cools the water some but represents a threat since the entrapped water results in a prolonged heat supply. The liquid temperature turned out to be the most important injury parameter, where liquid temperature of about 80–85 °C seems to be a limit for developing superficial partial-thickness burns in the present minimum case, i.e., where the liquid just wets the fabric. Spilling water in excess of just wetting the fabric, more severe burns will develop at lower liquid temperatures due to the prolonged heat supply. Higher liquid temperatures will nearly instantly develop more severe burns. It is demonstrated that removal of the clothing within the first seconds after the spill may significantly reduce the scalding severity. The general advice is therefore to avoid excessive heating of beverages and, if the beverage is spilled, to quickly remove the wetted clothing. Prolonged tempered water cooling is advised to improve the healing processes.

Pattern of Road Traffic Injuries in Rural Bangladesh: Burden Estimates and Risk Factors

Globally, road traffic injury (RTI) causes 1.3 million deaths annually. Almost 90% of all RTI deaths occur in low- and middle-income countries. RTI is one of the leading causes of death in Bangladesh; the World Health Organization estimated that it kills over 21,000 people in the country annually. This study describes the current magnitude and risk factors of RTI for different age groups in rural Bangladesh. A household census was carried out in 51 unions of seven sub-districts situated in the north and central part of Bangladesh between June and November 2013, covering 1.2 million individuals. Trained data collectors collected information on fatal and nonfatal RTI events through face-to-face interviews using a set of structured pre-tested questionnaires. The recall periods for fatal and non-fatal RTI were one year and six months, respectively. The mortality and morbidity rates due to RTI were 6.8/100,000 population/year and 889/100,000 populations/six months, respectively. RTI mortality and morbidity rates were significantly higher among males compared to females. Deaths and morbidities due to RTI were highest among those in the 25–64 years age group. A higher proportion of morbidity occurred among vehicle passengers (34%) and pedestrians (18%), and more than one-third of the RTI mortality occurred among pedestrians. Twenty percent of all nonfatal RTIs were classified as severe injuries. RTI is a major public health issue in rural Bangladesh. Immediate attention is needed to reduce preventable deaths and morbidities in rural Bangladesh.

Epidemiology of Fall Injury in Rural Bangladesh

Globally, falls are the second leading cause of unintentional injury deaths, with 80% occurring in low-and middle-income countries. The overall objective of this study is to describe the burden and risk factors of falls in rural Bangladesh. In 2013, a large household survey covering a population of 1,169,593 was conducted in seven rural sub-districts of Bangladesh to assess the burden of all injuries, including falls. The recall periods for non-fatal and fatal injuries were six and 12 months, respectively. Descriptive, bivariate and multiple logistic regression analyses were conducted. The rates of non-fatal and fatal falls were 36.3 per 1000 and 5 per 100,000 population, respectively. The rates of both fatal and non-fatal falls were highest among the elderly. The risk of non-fatal falls was higher at extremes of age. Lower limb and waist injuries were frequent following a fall. Head injuries were frequent among infants (35%), while lower limb and waist injuries were frequent among the elderly (>65 years old). Injuries to all body parts (except the waist) were most frequent among men. More than half of all non-fatal falls occurred in a home environment. The injury patterns and risk factors of non-fatal falls differ by sociodemographic factors.

Care-Seeking Patterns and Direct Economic Burden of Injuries in Bangladesh

This study provides a comprehensive review of the care-seeking patterns and direct economic burden of injuries from the victims’ perspective in rural Bangladesh using a 2013 household survey covering 1.17 million people. Descriptive statistics and bivariate analyses were used to derive rates and test the association between variables. An analytic model was used to estimate total injury out-of-pocket (OOP) payments and a multivariate probit regression model assessed the relationship between financial distress and injury type. Results show non-fatal injuries occur to 1 in 5 people in our sample per year. With average household size of 4.5 in Bangladesh--every household has an injury every year. Most non-fatally injured patients sought healthcare from drug sellers. Less than half of fatal injuries sought healthcare and half of those with care were hospitalized. Average OOP payments varied significantly (range: $8–$830) by injury type and outcome (fatal vs. non-fatal). Total injury OOP expenditure was $355,795 and $5000 for non-fatal and fatal injuries, respectively, per 100,000 people. The majority of household heads with injuries reported financial distress. This study can inform injury prevention advocates on disparities in healthcare usage, OOP costs and financial distress. Reallocation of resources to the most at risk populations can accelerate reduction of preventable injuries and prevent injury related catastrophic payments and impoverishment.
