Analysis of Underwear Used with Protective Clothing Worn by Metallurgy Workers and Welders – Research Survey

Employees of the metallurgy industry and welders are constantly exposed to a hot factors and hot microclimate in working environment. Difficult working conditions associated with expose employees to hot factors occurring in the form of flame, contact heat, convective heat, and splashes of molten metal may consequently lead to extensive body burns and even death. Scientific publications have proven that the temperature of the working environment is an important factor affecting human safety and performance. Improved comfort and safety can be achieved by using properly selected clothing and underwear/undergarment, meeting the requirements for a specific occupational group. In order to obtain information regarding underwear/undergarments usually used under protective clothing as well as to get acquainted with expectations regarding the subject matter, questionnaire surveys were conducted among two professional groups, namely employees of the metallurgy and welders, who are constantly exposed to a hot factors and hot microclimate.

Epidemiology and factors associated with acute stress disorder in burned patients: a case-control study

IntroductionA burn injury is a very painful experience, with subsequent emotional problems, which have been gaining relevance to the extent that survival from burns has improved. Among the alterations of the mental sphere in this population is Acute Stress Disorder (ASD) that has been described in up to one-third of patients with major burns. MethodologyA nested case-control study was carried out in a cohort of hospitalized patients in a burn referral unit, in patients over 16 years of age. A total of 135 patients, 41 cases, and 94 controls were included. All of them underwent a psychiatric interview, a standardized form was filled out on sociodemographic and clinical information, and the PID-5-BF scale was applied to evaluate associated personality elements. The diagnosis of acute stress was made with the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria. ResultsThe incidence of acute stress was 23.4%. When the clinical and sociodemographic characteristics of both the cases and the controls were compared, the risk factors were subsidized insurance, flame burn, burn in a special area, third-degree burn, high pain, stay in the Intensive Care Unit (ICU), peritraumatic amnesia and life threat. Patients also had a higher percentage of burned body surface, higher average pulse, longer hospital length of stay, higher average in the negative affect variable and in the psychoticism variable of the PID-5-BF scale. But for the multivariate analysis using logistic regression, the model that best explains the presence of acute stress only includes the variables life threat (Odds Ratio adjusted (ORa): 117.0; Confidence Interval (CI): 10.9–1258.5), severe pain (ORa: 9.9; CI: 1.8–52.8), electrical burn (ORa: 20.8; CI: 17.2–250), burn in a special area (ORa: 8.9; CI: 1, 0–76.8), third-degree burn (ORa: 10.4; CI: 0.7–166.7). ConclusionAcute stress disorder is frequent in the hospitalised burn population, and is more frequent than in other types of trauma. Associated factors with the presentation of Acute Stress Disorder are the feeling of life threat at the time of the burn, having pain classified as strong (Visual Analog Scale (VAS) 5–10), electrical burn, and burns in special areas.

Characterization of severely burned patients and evaluation of factors associated to mortality. An observational retrospective cohort study in San Vicente Fundación Hospital

Introduction Burns are common in developing countries and place a large burden on the medical and social care systems. However, information about management and outcomes from such countries is scarce. The purpose of this study was to analyze the epidemiology and main factors related to the mortality in severely burned patients at the Hospital Universitario San Vicente Fundación in Medellín, Colombia. Methods An observational retrospective cohort study was conducted. To establish prognostic factors associated with mortality, we analyzed variables such as age, sex, burned surface, and degree of burn, among others. Demographic, clinic, and management features as well as complications and factors associated with mortality were analyzed using logistic regression. Results 4516 clinical histories were reviewed, 225 were included in the study. 76.9% were men, with a median age of 35 years; 64.9% were fire burns. The median burned body surface area was 42%. There were inhalation injuries in 135 patients and ocular in 106 patients. The main complication was infection followed by rhabdomyolysis. The overall hospital stay was 27 days, and the median length of stay at the intensive care unit was 7 days with in-hospital mortality of 30.7%. The variables associated with mortality were age, burned body surface area, degree of burn, and kidney injury. Surgical intervention was protective. Conclusions Severely burned patients in our hospital have similar outcomes and, in some cases, better outcomes than those reported in the literature in countries with similar characteristics, and we have seen that in the last years, there has been a better experience in the management of these patients. Elderly, extension, and depth of burnt tissue are markers of poor outcomes. Early surgery and intubation have shown better outcomes, probably due to infection control and removal of necrotic tissue, airway management, and ventilatory support for metabolic and hemodynamic derangement.

Burn depth assessment using hyperspectral imaging in a prospective single center study

The assessment of thermal burn depth remains challenging. Over the last decades, several optical systems were developed to determine burn depth. So far, only laser doppler imaging (LDI) has been shown to be reliable while others such as infrared thermography or spectrophotometric intracutaneous analysis have been less accurate. The aim of our study is to evaluate hyperspectral imaging (HSI) as a new optical device. Patients suffering thermal trauma treated in a burn unit in Germany between November 2019 and September 2020 were included. Inclusion criteria were age ≥18 years, 2nd or 3rd degree thermal burns, written informed consent and presentation within 24 h after injury. Clinical assessment and hyperspectral imaging were performed 24, 48 and 72 h after the injury. Patients in whom secondary wound closure was complete within 21 days (group A) were compared to patients in whom secondary wound closure took more than 21 days or where skin grafting was indicated (group B). Demographic data and the primary parameters generated by HSI were documented. A Mann Whitney-U test was performed to compare the groups. A p-value below 0.05 was considered to be statistically significant. The data generated using HSI were combined to create the HSI burn index (BI). Using a logistic regression and receiver operating characteristics curve (ROC) sensitivity and specificity of the BI were calculated. The trial was officially registered on DRKS (registration number: DRKS00022843). Overall, 59 patients with burn wounds were eligible for inclusion. Ten patients were excluded because of a poor data quality. Group A comprised 36 patients with a mean age of 41.5 years and a mean burnt body surface area of 2.7%. In comparison, 13 patients were allocated to group B because of the need for a skin graft (n = 10) or protracted secondary wound closure lasting more than 21 days. The mean age of these patients was 46.8 years. They had a mean affected body surface area of 4.0%. 24, 48, and 72 h after trauma the BI was 1.0 ± 0.28, 1.2 ± 0.29 and 1.55 ± 0.27 in group A and 0.78 ± 0.14, 1.05 ± 0.23 and 1.23 ± 0.27 in group B. At every time point significant differences were demonstrated between the groups. At 24 h, ROC analysis demonstrated BI threshold of 0.95 (sensitivity 0.61/specificity 1.0), on the second day of 1.17 (sensitivity 0.51/specificity 0.81) and on the third day of 1.27 (sensitivity 0.92/specificity 0.71). Changes in microcirculation within the first 72 h after thermal trauma were reflected by an increasing BI in both groups. After 72 h, the BI is able to predict the need for a skin graft with a sensitivity of 92% and a specificity of 71%.

Response of Aerobic Capacity to Low-Level Laser Therapy in Burned Patients.

Severe burns lead to decreased pulmonary function and impaired aerobic capacity for long periods postinjury. Low-level laser therapy is a modality used to improve aerobic capacity, enhance exercise performance, and increase the time until fatigue when used before aerobic exercises. This work aims to determine the impacts of pre-exercise low-level laser therapy on aerobic capacity in burn cases. Sixty adults burned cases of both sex, aged from 25 to 40 years, with second-degree healed thermal burns, and the total burned body surface area ranged from 20 to 40% participated in this study after complete wound healing. They were randomly categorized into two groups of equal numbers. The study group received low-level laser therapy before aerobic exercises, three sessions per week for 12 weeks, while the control group performed aerobic exercises three times weekly for 12 weeks. All cases received the routine physical treatment program. Aerobic capacity was assessed for both groups by measuring maximum oxygen consumption and time to exhaustion at baseline and 12 weeks following interventions. There was a statistically significant rise in the mean values of maximum oxygen usage and time to fatigue after 12 weeks of treatment in both groups. However, after comparison, the improvements in the study group were statistically significant than those in the control group with P < .01 and P < .05, respectively. Low-level laser therapy has a beneficial therapeutic impact on promoting aerobic capacity, improving maximum oxygen consumption, and increasing treadmill time in burned cases when preceding aerobic exercises.

Effect of postmortem interval and conditions of teeth on STR based DNA profiling from unidentified dead bodies

Teeth are important exhibits to establish the identity of unidentified dead bodies by DNA profiling. Tooth acts as a cage to protect DNA from harsh environmental conditions. Unidentified bodies are sometimes found many years after death causing loss of valuable soft tissues which can be used for DNA extraction. Skeletal remains and dental evidence provide the best alternative when decomposed or burnt bodies are examined to establish the identity. In this study, the powder-free method was used to extract DNA from ninety-five teeth of unidentified dead bodies across seven years (2014–2020). Intact and broken dental remains were analyzed majorly from decomposed remains. The present study reports successful STR profiles obtained from dental evidence using powder free method. Complete DNA profiles were obtained from intact teeth while damaged teeth either gave partial profiles or no results. This data suggest that intact teeth are excellent samples for DNA profiling from decomposed unidentified dead bodies even with greater post mortem interval. Findings from this study can hence be useful in establishing the identity in forensic and archeological casework.

Wound healing activity of Allium cepa L. bulbs in a second-degree burn wound model in Holtzman rats

Background: The bulb of Allium cepa Linnaeus (onion) is used in traditional medicine as an antidiabetic, antioxidant, antihypertensive, anti-inflammatory, and antihyperlipidemic, among others. The lack of information or little knowledge about the effects of Allium cepa L. on skin lesions, specifically burn wounds, arouses interest in studying its effects on these skin disorders. Objective: This study assessed the wound healing activity of Allium cepa L. on second-degree burns induced in Holtzman rats. Method: Thirty-two albino rats were randomly distributed into four groups of 8 rats each, including the Healthy group, the Control group, the Experimental group (Allium cepa L.), and the Standard group (1% silver sulfadiazine). Burn wounds were induced, and topical treatments were performed daily for 21 days. The reduction of the burned body area (mm2) was determined during the experimental time. Albino rats were sacrificed with an excess of surgical anesthesia to obtain tissue samples for histopathological analysis. Results: Standard and experimental groups significantly reduced burned body area (p&lt;0.01) compared to the control group. Histopathological studies showed hyperemic chorion in the Control group, fibroblasts, and collagen in the Standard group, and dermis composed of a reticular stratum of fibroblasts, collagen, and few blood vessels in the Experimental group. Conclusion: Allium cepa L. revealed wound-healing activity on burns induced in Holtzman rats and reduced the damage produced by burns.

Facial Burns: A One Year Audit at a Tertiary Hospital in Dar Es Salaam, Tanzania

Abstract Background: Facial burn injuries have plagued mankind since time immemorial and till the present day, they remain among the major public health problems. Since the face carries the identity of an individual, it is the most psychologically significant area of the body. Therefore, any disfigurement to the face such as that caused by burns has potential psychosocial consequences to the victim. The present study aimed at determining the etiology, pattern of occurrence and management of facial burns among patients attended at Muhimbili National Hospital, Dar es Salaam Tanzania. Material and methods: This was a one-year prospective study of all consecutive patients with facial burns who attended treatment at the Muhimbili National Hospital (MNH). The variables examined included socio-demographic characteristics, etiology, clinical features and management of facial burns. The data were analyzed using SPSS software for windows version 23 (IBM Corporation Chicago, IL, USA). Fisher's t-test was used and associations were considered significant when p < 0.05. Results: A total of 112 patients with body burn injuries were attended during the period of this study where by 29.5% of the patients had burn injuries to the facial region. The male to female ratio was 2:1 and patient's age ranged from 17 to 70 years, with a mean age of 30.6 (SD 12.3) years. The etiological factors included open fire that affected (78.8%) of the patients followed by scalding (12.1%) and electricity (9.1%). Majority (81.8%) of the burn injuries were accidental in nature. The most frequently burnt facial aesthetic zones were the zygomatic region followed by the orbits. More than 80% of the participants had complications where by hypo-pigmentation was the commonest (51%) complication of burn injuries encountered. Conclusion: Facial burns affected males twice more than females. Open fire was the most common etiological factor and the zygoma was the most frequently affected facial esthetic zone. Majority of the patients had complications due to burn injury, of which the facial skin hypo-pigmentation was the commonest followed by death.

BACKGROUND Forensic odontology is a branch of dentistry which deals with appropriate handling and examination of dental evidences and with the proper evaluation and presentation of dental findings in the interest of justice. Identification of an individual is a prerequisite for certification of death and for personal, social and legal reasons. Palatal rugae are permanent and unique to each person, and can be used by clinicians and scientists to establish identity. It can be of special interest in edentulous cases and also in certain conditions, such as burned bodies or bodies that underwent severe decomposition. Thus the uniqueness, postmortem resistance, overall stability and additionally low utilization cost makes palatal rugae ideal forensic identification parameters. We wanted to compare the various palatal rugae patterns between dentate and edentulous subjects and also determine the comparison of the distribution of rugae number, length, shape, direction, unification between dentate and edentulous subjects. METHODS The study sample consisted of 60 subjects, 30 dentulous and 30 edentulous from JSS Dental College &amp; Hospital, Mysuru. The study group was equally divided between the sex, and was observed for number, length, shape, direction and unification of all palatal rugae. RESULTS The total number of rugae was higher in the dentulous group than in the edentulous group. In edentulous group, shorter lengths, lesser complexity rugae were seen compared to dentulous subjects. The total number of rugae on the right side in dentulous casts were 4.20 ± 1.06, while the total number on right side in Edentulous casts were 4.16 ± 0.79. On the left side mean total number of rugae in dentulous casts was 4.46 ± 0.79 whereas the mean total number of rugae in edentulous casts was 3.76 ± 0.77. CONCLUSIONS Palatal rugae pattern changed greatly after aging and loss of teeth regardless of time of edentulism and wearing denture.

Face Burns: A 4-Year Experience.

Burns on the face pose unique management challenges because they are in a place that is constantly visible, so scars are hard to hide. The goal of this study was to review our experience of adult patients who had face burns. We performed a retrospective review of adult patients (≥18 years old) who were admitted to a regional burn center from July 2015 to June 2019 with face burns. Sex, age, ethnicity, burn etiology, burn size, and discharge status were collected from electronic medical records of the patients who met study criteria. Descriptive statistics, Student's t-tests, and chi-square tests were performed in Stata/SE 16.1. Significance was defined as a P-value < .05. In 4 years, 595/1705 patients (~35% of admissions) were admitted with face burns. The mean age was 44.9 ± 17.0 (mean ± SD) years, with the majority being men (475, 80%). The mean burn size was 19.8 ± 20.9% TBSA with 10.1 ± 19.8% TBSA being third degree. The mean head burn size for any face burn was 2.8 ± 1.8% TBSA. The majority of burns were due to flames (478, 80%) and of those 122 (21%) were from accelerant use and 43 (7%) resulted from propane or butane use. Scalds caused 53 (9%), electric 25 (4%), hot tar 5 (1%), and chemical 5 (1%). Overall, 208 (35%) patients had grafting of some portion of their body, but only 31 patients (5.2%) had face grafting. The mean age of those with face grafting compared with patients who did not need grafting was 45.9 ± 13.8 and 44.9 ± 17.2 years, respectively. Patients who needed grafting had a mean third-degree burn size of 31.7 ± 25.4% TBSA and a mean head (including face) burn size of 4.7 ± 2.0% TBSA, whereas patients who did not need grafting had a mean third-degree burn size of 8.9 ± 18.7% TBSA and a mean head burn size of 2.7 ± 1.8% head TBSA. Patients requiring face grafts had longer lengths of stay, intensive unit stays, ventilator days, and mortality than those whose face burns healed spontaneously. Overall, head burns in adults were common within the 4-year time span we studied, but only a small fraction (5%) had face grafts. The patients who needed grafting for their head burns had significantly larger total body and face burns and had a 2.4-fold higher mortality rate compared to patients who did not need grafting. Most face burns were caused by flame, especially the use of accelerants or flammable gases. Prevention efforts should focus on avoiding the use of accelerants and being careful with flammable gases.

Age Related Lumbar Trabecular Bone in a Thai Population

Within spinal column, the lumbar vertebrae are the most durable and usually left behind in severely burnt body. European studies have reported that these vertebrae are useful for age estimation. However, it is widely acknowledged that different ancestry necessitates different methods and includes a range of variables, therefore a study specific to Thai population is needed for accuracy in the identification of Thai individuals. To investigate the correlation between lumbar vertebrae, and age of the individual, L1-L5 drilled out from 75 Thai cadavers. After undergoing histological processing each slide was photographed. The images were processed using an image processing technique to calculate the percentage of trabecular bone area over total area (%TBA/TA). Using the Statistical Package for the Social Sciences (SPSS) program, %TBA/TA of L1-L5 was calculated. The %TBA/TA of L1-L5 showed a negative correlation to age in both male and female groups. The %TBA/TA of L2 in the male group decreased most significantly with increase in age (r=-0.775) whereas in the female group, L3 showed the strongest negative correlation with age (r=-0.75. In the conclusion, it was found that trabecular bone of L2 showed the most significant correlation to increase in age in males whereas L3 showed the strongest correlation in females. Keywords: Age, Image segmentation, Lumbar, Thai population, Trabecular bone

Health-Related Quality of Life and Its Associated Factors Among Burn Patients at Governmental Referral Hospitals of Amhara Regional State, Northwest Ethiopia, 2020: Institutional-Based Cross-Sectional Study.

IntroductionBurns can have a considerable negative impact on physical and psychosocial functioning that affects the quality of life. The physical and psychological manifestations may compromise the quality of life of burned patients. The aim is to assess health-related quality of life and associated factors among burn patients at Amhara regional state governmental referral hospitals, Northwest Ethiopia, 2020.MethodsInstitution-based cross-sectional study was conducted from June 01 to July 15, 2020, in Amhara National regional state governmental referral hospitals. Systematic random sampling technique was used, and data were collected using structured Burn Specific Health Scale Brief Questionnaire through face-to-face interview and document review from patients time since burn 15 days and above. Data were entered into Epidata, and analysis was done by SPSS version 25. Descriptive statistics were computed, and binary logistic regression analysis was used to determine the association between the dependent and independent variables. Variables with a p-value of ≤0.05 in the multivariable analysis were considered statistically significant.ResultsOf 423 study participants, 95.7% responded completely. Among the respondents, 58.8% (group mean and median of 18.38 and 21) for physical domain and 57% (group mean and median of 44.73 and 53) for generic domains had a poor health-related quality of life. Overall poor health-related quality of life was 57.5% with a mean of 63.12. Third-degree burn, exposed burnt body part, total body surface area burned ≥20%, having an amputation and having a co-morbid illness with (P = 0.001) were associated with poor health-related quality of life.Conclusion and RecommendationThis study revealed that more than half of the burn survivors had poor health-related quality of life. There shall be strengthened long-term physical and psychosocial domains (generic) intervention for burn survivors by giving more concern for those with the identified risk factors.

Technical and Medical Aspects of Burn Size Assessment and Documentation.

In burn medicine, the percentage of the burned body surface area (TBSA-B) to the total body surface area (TBSA) is a crucial parameter to ensure adequate treatment and therapy. Inaccurate estimations of the burn extent can lead to wrong medical decisions resulting in considerable consequences for patients. These include, for instance, over-resuscitation, complications due to fluid aggregation from burn edema, or non-optimal distribution of patients. Due to the frequent inaccurate TBSA-B estimation in practice, objective methods allowing for precise assessments are required. Over time, various methods have been established whose development has been influenced by contemporary technical standards. This article provides an overview of the history of burn size estimation and describes existing methods with a critical view of their benefits and limitations. Traditional methods that are still of great practical relevance were developed from the middle of the 20th century. These include the “Lund Browder Chart”, the “Rule of Nines”, and the “Rule of Palms”. These methods have in common that they assume specific values for different body parts’ surface as a proportion of the TBSA. Due to the missing consideration of differences regarding sex, age, weight, height, and body shape, these methods have practical limitations. Due to intensive medical research, it has been possible to develop three-dimensional computer-based systems that consider patients’ body characteristics and allow a very realistic burn size assessment. To ensure high-quality burn treatment, comprehensive documentation of the treatment process, and wound healing is essential. Although traditional paper-based documentation is still used in practice, it no longer meets modern requirements. Instead, adequate documentation is ensured by electronic documentation systems. An illustrative software already being used worldwide is “BurnCase 3D”. It allows for an accurate burn size assessment and a complete medical documentation.

Severe Altered Immune Status After Burn Injury Is Associated With Bacterial Infection and Septic Shock

Introduction: Burn injury is associated with a high risk of death. Whether a pattern of immune and inflammatory responses after burn is associated with outcome is unknown. The aim of this study was to explore the association between systemic immune and inflammatory responses and outcome in severely-ill burn patients.Materials and Methods: Innate immunity, adaptive immunity, activation and stress and inflammation biomarkers were collected at admission and days 2, 7, 14, and 28 in severely-ill adult burn patients. Primary endpoint was mortality at day 90, secondary endpoint was secondary infections. Healthy donors (HD) served as controls. Multiple Factorial Analysis (MFA) was used to identify patterns of immune response.Results: 50 patients were included. Age was 49.2 (44.2–54.2) years, total burn body surface area was 38.0% (32.7–43.3). Burn injury showed an upregulation of adaptive immunity and activation biomarkers and a down regulation of innate immunity and stress/inflammation biomarkers. High interleukin-10 (IL-10) at admission was associated with risk of death. However, no cluster of immune/inflammatory biomarkers at early timepoints was associated with mortality. HLA-DR molecules on monocytes at admission were associated with bacterial infections and septic shock. Later altered immune/inflammatory responses in patients who died may had been driven by the development of septic shock.Conclusion: Burn injury induced an early and profound upregulation of adaptive immunity and activation biomarkers and a down regulation of innate immunity and stress/inflammation biomarkers. Immune and inflammatory responses were associated with bacterial infection and septic shock. Absence of immune recovery patterns was associated with poor prognosis.

RETRACTED: Genetic Algorithm to Optimize the Design of High Temperature Protective Clothing Based on BP Neural Network

For the clothing design for high-temperature operation, the theory or method such as partial differential, nonlinear programming and finite difference method was first applied to construct the overall heat transfer model of “high temperature environment--clothing--air layer--skin” and draw the temperature distribution map. Secondly, according to the human body burn model, the optimal parameters of fabric thickness are obtained preliminarily. Finally, the weights and thresholds of BP neural network were optimized by genetic algorithm, and these optimized values were assigned to the optimized BP neural network, and the nonlinear thickness function was approximated and optimized with MATLAB.

EPIDEMIOLOGICAL PROFILE OF CHILDREN VICTIMS OF BURNS ATTENDED IN A REFERENCE HOSPI-TAL IN THE AMAZON

Background: Burns represent a traumatic situation in children. Such trauma is experienced after hospital discharge, when the child finds it difficult to interact in his social and family environment. Information is the most effective way to reduce the consequences generated by the burn. Objectives: To trace the epidemiological profile of children victims of burns who enter a referral hospital in the Amazon. Methods: This study was retrospective, descriptive, observational, cross-sectional and documentary, of a quantitative nature, carried out through analyzes in hospital records, from January 2016 to December 2018. Results: Of the 403 records analyzed, the gender male stood out with 237 (59%) and female 166 (41%); the burned body surface index was 0 to 10% with 210 (52%); the burn depth was 2nd degree, with 370 (92%) of the total cases; medical drug treatment, tramadol as the most used 180 (53%). As for clinical treatment with intervention, debridement indicated a higher prevalence 340 (84%) of cases. In physical therapy treatment, 255 (63%) did not undergo any type of physical therapy intervention, 389 (97%) did not present any complications during hospitalization. Conclusions: Studies to date are scarce with specific and detailed data on the subject, so that effective intervention strategies are provided in order to reduce this trauma in children, especially in the most prevalent age group of this study.

Tratamento ortodôntico em paciente com queimadura facial – relato de caso

Numerous variables are considered in a normal occlusion, one of those is the homeostasis of the facial musculature and its harmony with bones and teeth. Several factors can lead to change in muscle functionality. An example is the facial burn injury in which it is common formation of hypertrophic scars that cause muscle structures dysfunction and impact on facial growth and dentition development. Patient K.R.S, 15-years-old, female, sought treatment at the Center for Attention and Research of Craniofacial Anomalies (CEAPAC) complaining of “crooked teeth”. She reported during anamnesis that when she was a child, she suffered a domestic accident which caused facial, and body burn injury. The patient had Angle Class I malocclusion and upper and lower incisor lingualization. Dental arch atresia and moderate crowding were observed. Rapid maxillary expansion and lower dental expansion were performed with the lip bumper, followed by teeth alignment and leveling with a fixed appliance. n the retainment phase, Hawley plates (upper and lower) were used in addition to a fixed lower retainer. The treatment of arch expansion and alignment proved to be viable and predictable, however, the stability has a dubious prognosis, which led the authors to indicate the use of retainers indefinitely.

Psychotraumatism in Burning Accident Victims: About 50 Patients at the Abidjan Burns Center

Among the potentially traumatic events, burn accidents have the particularity of damaging the physical integrity of the victims while leaving psychological scars. The objective of this study is to investigate the attribution of post-traumatic stress disorder (PTSD) to the presence of extensive body burn. This was a cross-sectional descriptive and analytical study that took place from May to August 2017 and which involved (50) fifty patients labeled severe burns. The burns were second degree superficial (63.50%) and affected between 1 and 10% of the body surface in 72% of cases. The event appealed to a sense of horror at the mention (28%). Post-traumatic stress disorder was found in 6% of victims. The chi-square test found a significant dependence with a P-value of 0.0043 between the PTSD score and the body surface area burned. The extent of the burn injuries in the victims, in addition to reflecting the severity of the accident, is a risk factor associated with the occurrence of psychotrauma. In a dual preventive and therapeutic approach, psychotraumatological follow-up should be offered to any major burn victim.

Life, death, and the destruction of architecture: Hunter-gatherer mortuary behaviors in prehistoric Jordan

The end of the Pleistocene in Southwest Asia is widely known for the emergence of socially-complex hunter-gatherers—the Natufians—characterized by a rich material culture record, including elaborate burials. In comparison, human interments that predate the Natufian are rare. The discovery and excavation of a hut structure at the 20,000-year-old Epipalaeolithic site of Kharaneh IV in eastern Jordan reveals the remains of an adult female intentionally placed in a semi-flexed position on one of the structure’s floors. The structure was burned down shortly after her deposition, extensively charring the human remains. The burying of the dead within structures and the burning of domestic structures are well-known from later Neolithic periods, although their combination as a mortuary practice is rare. However, for the Early Epipalaeolithic, the burning of a structure containing the primary deposition of human remains is novel and signifies an early appearance for the intentional burning of bodies as a mortuary treatment and symbolic behaviors associated with the interrelated life histories of structures and people.
