ABSTRACT

Introduction: Facial injuries are a common occurrence at the emergency room. Treatment for this type of trauma is complex in terms of re-establishing good oral and facial function, plus aesthetics. Objective: This paper aims to report a clinical case of aesthetic and functional rehabilitation using triamcinolone in a patient affected on the face by a fireworks explosion. Case report: A 26-year-old man was admitted to the oral and maxillofacial surgery service of the Sergipe Urgency Hospital presenting trauma after the explosion of a "Firework rocket" in his face. The patient had extensive soft tissue injury in gingival mucosa, right labial commissure, and tongue. There was also inferior incisive avulsion and dentoalveolar fracture. His clinical and tomographic evaluation presented comminuted mandibular fracture. After eighteen days he was discharged and sent to the dentistry service of the Federal University of Sergipe for aesthetic and functional rehabilitation of his facial damages. Two months later, the patient attended a University dental service to begin aesthetic and postoperative functional rehabilitation. First, the necrotic bone was removed, following intralesional infiltration of hexacetonide triamcinolone 20mg/mL into the scar of the labial region and the commissure of the lips was performed. Each application was performed after twenty days of interval. Later, lingual frenectomy and glossosplasty were done for improving his lingual mobility and then hexacetonide triamcinolone 20mg/mL infiltrations were also done in the tongue base in the following sessions. Conclusions: After five infiltrations, it was observed an improvement in the scar appearance and texture, which also had a lower contracture, as well as a lingual motricity improvement(AU)


Introducción: Las lesiones faciales son frecuentes en el servicio de emergencia. El tratamiento para este tipo de trauma es complejo en términos de restablecer una buena función bucal y facial, además de la estética. Objetivo: Reportar un caso clínico de rehabilitación estética y funcional a través del uso de hexacetónido de triamcinolona en un paciente afectado por una explosión de fuegos artificiales en su rostro. Caso clínico: Hombre de 26 años ingresado en el servicio de cirugía oral y maxilofacial del Hospital de Urgencia de Sergipe por presentar un traumatismo después de la explosión contra su rostro de un cohete de fuegos artificiales. El paciente tenía una lesión extensa de partes blandas en la mucosa gingival, comisura labial derecha y lengua. También hubo avulsión incisiva inferior y fractura dentoalveolar. A través de la evaluación clínica y de tomografía, fue posible observar fragmentación múltiple ósea en el sitio de la fractura, compatible con fractura mandibular conminuta. Después de dieciocho días fue dado de alta y enviado al servicio de odontología de la Universidad Federal de Sergipe para la rehabilitación estética y funcional de sus daños faciales. Dos meses después, el paciente asistió al servicio dental de la universidad para comenzar la rehabilitación funcional estética y posoperatoria. Primero, se retiró el hueso necrótico, luego se realizó la infiltración intralesional de hexacetónido de triamcinolona 20 mg/mL en la cicatriz de la región labial y se realizó la comisura de los labios; con un intervalo de 20 días entre cada aplicación. Posteriormente, se realizaron frenectomía lingual y glososplastia, para mejorar su movilidad lingual, y luego se realizaron infiltraciones de 20 mg/mL de hexacetónido de triamcinolona en la base de la lengua en las sesiones siguientes. Comentarios principales: Después de cinco infiltraciones se observó una mejora en el aspecto y la textura de la cicatriz, que también tenía una contractura más baja, así como una mejora de la motricidad lingual(AU)

ABSTRACT

Objective@#To observe the dynamic impacts of shock waves on the severity of lung injury in rats with different injury distances.@*Methods@#Simulate open-field shock waves; detect the biomechanical effects of explosion sources at distances of 40, 44, and 48 cm from rats; and examine the changes in the gross anatomy of the lungs, lung wet/dry weight ratio, hemoglobin concentration, blood gas analysis, and pathology.@*Results@#Biomechanical parameters such as the overpressure peak and impulse were gradually attenuated with an increase in the injury distance. The lung tissue hemorrhage, edema, oxygenation index, and pathology changed more significantly for the 40 cm group than for the 44 and 48 cm groups. The overpressure peak and impulse were significantly higher for the 40 cm group than for the 44 and 48 cm groups ( < 0.05 or < 0.01). The animal mortality was significantly higher for the 40 cm group than for the other two groups (41.2% . 17.8% and 10.0%, < 0.05). The healing time of injured lung tissues for the 40 cm group was longer than those for the 44 and 48 cm groups.@*Conclusions@#The effects of simulated open-field shock waves on the severity of lung injuries in rats were correlated with the injury distances, the peak overpressure, and the overpressure impulse.

ABSTRACT

The burn center in our hospital is a national and regional (Southeast Asia) center. Of all admissions, 10% are related to blast explosions, and 8% due to chemical burns. In the acute burn management protocol of Singapore General Hospital, early surgical debridement is advocated for all acute partial-thickness burns. The aim of early surgical debridement is to remove all debris and unhealthy tissue, preventing wound infection and thereby expediting wound healing. In chemical burns, there can be stubborn eschars that are resistant to traditional debridement. We would like to present a novel technique using the diathermy scratch pad as a cheap and efficient tool for the dual purpose of surgical debridement and dermabrasion.

ABSTRACT

PURPOSE: The Iri station explosion that occurred in 1977 was a major social disaster in Korea, caused by a fire in a train equipped with explosives. The purpose of this study was to investigate the social disaster adaptation experiences of railroad workers. METHODS: This study was based on qualitative research using phenomenological methodology. Participants were six railroad workers who experienced the Iri station explosion. Data were collected through in-depth interviews with individual workers from March to June, 2018. The data analysis method was based on Colaizzi's approach. RESULTS: Experiences of railroad workers were categorized into 12 themes and the following 6 theme clusters: (1) Anxiety due to the extreme vibration and crash, (2) Terror regarding the horrible situation that one cannot face, (3) Anger about the cause of the explosion and a sense of relief about survival, (4) Confusion regarding different rumors, (5) Various efforts to return to daily life, and (6) Trauma that continues to exist. CONCLUSION: The findings of this study recommend that railroad organizations and managers should pay attention to enhance disaster preparedness and develop organizational disaster coping guidelines for members. The results of this study can help us to better understand the various aspects of the Iri station explosion of 1977.

ABSTRACT

Although the rare earth elements (REEs) recycling industry is expected to increase worldwide in high-tech industry, regulations for worker safety have yet to be established. This study was conducted to understand the potential hazard/risk of REE recycling and to support the establishment of regulations or standards. We review the extensive literature on the toxicology, occupational safety, and health issues, and epidemiological surveys related to the REEs, and propose suitable management measures. REE recycling has four key steps such as collection, dismantling, separation, and processing. In these processes, hazardous substances, such as REEs-containing dust, metals, and chemicals, were used or occurred, including the risk of ignition and explosion, and the workers can be easily exposed to them. In addition, skin irritation and toxicities for respiratory, nervous, and cardiovascular systems with the liver toxicity were reported; however, more supplementary data are needed, owing to incompleteness. Therefore, monitoring systems concerning health, environmental impacts, and safety need to be established, based on additional research studies. It is also necessary to develop innovative and environment-friendly recycling technologies, analytical methods, and biomarkers with government support. Through these efforts, the occupational safety and health status will be improved, along with the establishment of advanced REE recycling industry.

ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the characteristics of the emergency medical services (EMS) response and clinical information on mass casualty chemical incidents in Korea. METHODS: This retrospective observational study analyzed the integrated data of the EMS rescue records and EMS-treated severe trauma registry from January 2012 to December 2013. Two databases were integrated using the unique accident identification number. Chemical incidents were defined by an in-depth review of the EMS rescue records according to a previous study. Mass casualty incidents were defined as more than 6 injured individuals. The rescue, EMS, and hospital variables of mass casualty chemical incidents were analyzed. RESULTS: A total of 8 mass casualty chemical incidents and 73 patients were included. The mean responded rescue vehicles and EMS vehicles were 2.4 and 3.5, respectively. The 4 incidents were an oil spill due to traffic accidents and most patients suffered minor trauma. A carbon monoxide leak caused the largest number of patients (23 people). The explosion caused by flammable polyethylene leaks showed the highest severity. In that explosion, the mortality rate was 40% and 8 patients had a disability at discharge. CONCLUSION: This study evaluated the characteristics of the EMS response and clinical information on mass casualty chemical incidents in Korea.

ABSTRACT

Sex determination is the preliminary step in every forensic investigation and the hard palate assumes significance in cranial sexing in cases involving burns and explosions due to its resistant nature and secluded location. This study analyzes the sexing potential of incisive foramen to posterior nasal spine length, palatine process of maxilla length, horizontal plate of palatine bone length and transverse length between the greater palatine foramina. The study deviates from the conventional method of measuring the maxillo-alveolar length and breadth as the dimensions considered in this study are more heat resistant and useful in situations with damaged alveolar margins. The study involves 50 male and 50 female adult dry skulls of Indian ethnic group. The dimensions measured were statistically analyzed using Student's t test, binary logistic regression and receiver operating characteristic curve. It was observed that the incisive foramen to posterior nasal spine length is a definite sex marker with sex predictability of 87.2%. The palatine process of maxilla length with 66.8% sex predictability and the horizontal plate of palatine bone length with 71.9% sex predictability cannot be relied upon as definite sex markers. The transverse length between the greater palatine foramina is statistically insignificant in sexing crania (P=0.318). Considering a significant overlap of values in both the sexes the palatal dimensions singularly cannot be relied upon for sexing. Nevertheless, considering the high sex predictability of incisive foramen to posterior nasal spine length this dimension can definitely be used to supplement other sexing evidence available to precisely conclude the cranial sex.

ABSTRACT

PURPOSE: The purpose of this study was to examine the burn characteristics of female patients hospitalized in a burn center. METHODS: This is a retrospective descriptive study. The subjects were 222 female patients aged over 19 years old having burn injuries from work sites between January 1, 2012 and December 31, 2014. Data were collected using electronic medical records about the burn-related characteristics. The data were analyzed descriptively. RESULTS: Many of the subjects were in their forties and fifties. Most subjects showed burns with an area of less than 10% of the body surface with a severity of second degree. Scalding burns were the most frequent. Contact burns were usually of third-degree severity and occurred on hands and wrists. Flame burns affected the largest body surface area and frequently occurred on the face and mainly caused by explosion of a stove or kitchen gas. Chemical burns frequently occurred on the lower limbs. CONCLUSION: Female workers are exposed to the hazards of burn injuries in industrial accidents. Types of burn differ depending on the workplace conditions. Therefore, preventative measures for burn injuries should be established in accordance with the characteristics of each industry to which female workers belong.

ABSTRACT

The prevalence of obesity is rapidly increasing worldwide, and its complications such as type 2 diabetes and cardiovascular disease are also increasing. To avoid long-term damage caused by obesity and its complications, we must develop preventive measures and therapeutic agents based on the pathophysiology of human obesity. However, genetically-modified rodents are mainly used for obesity research. This type of animal model is not very suitable for the study of human obesity because environmental factors such as excessive food intake and sedentary lifestyle are major causes of the recent explosion in human obesity. Therefore, diet-induced obesity rodent models are more appropriate for research in human obesity. Type of diet, animal species, duration of food intake, age, and sex can play a role in determining body weight and levels of glucose, insulin, triglycerides, and leptin. Animal housing conditions such as the number of animals per cage, ambient temperature, and length of the light-dark cycle also influence body weight and metabolic parameters. As a result, many influencing factors should be considered in the development of an appropriate diet-induced obesity rodent model for successful obesity research.

ABSTRACT

The search for new instruments to promote an appropriate cervical preparation has led to the development of new rotary instruments such as TripleGates. However, to the best of the authors' knowledge, there is no study evaluating TripleGates effect on the “risk zone” of mandibular molars. Objectives : The aim of this study was to evaluate the effects of a crown-down sequence of Gates-Glidden and TripleGates burs on the remaining cervical dentin thickness and the total amount of dentin removed from the root canals during the instrumentation by using cone beam computed tomography. The number of separated instruments was also evaluated. Material and Methods : Mesial roots of 40 mandibular first molars were divided into 2 equal groups: crown-down sequence of Gates-Glidden (#3, #2, #1) and TripleGates burs. Cervical dentin thickness and canal area were measured before and after instrumentation by using cone beam computed tomography and image analysis software. Student’s t-test was used to determine significant differences at p<0.05. Results : No significant differences (p>0.05) were observed between the instruments, regarding the root canal area and dentin wall thickness. Conclusion : Both tested instruments used for cervical preparation were safe to be used in the mesial root canal of mandibular molars. .

ABSTRACT

<p><b>OBJECTIVE</b>The 8.12 Tianjin Port Explosion in 2015 caused heavy casualties. Pingjin Hospital, an affiliated college hospital in Tianjin, China participated in the rescue activities. This study aims to analyze the emergency medical response to this event and share experience with trauma physicians to optimize the use of medical resource and reduce mortality of critical patients.</p><p><b>METHODS</b>As a trauma centre at the accident city, our hospital treated 298 patients. We retrospectively analyzed the data of emergency medical response, including injury triage, injury type, ICU patient flow, and medical resource use.</p><p><b>RESULTS</b>There were totally 165 deaths, 8 missing, and 797 non-fatal injuries in this explosion. Our hospital treated 298 casualties in two surges of medical demand. The first one appeared at 1 h after explosion when 147 wounded were received and the second one at 4 h when 31 seriously injured patients were received, among whom 29 were transferred from Tianjin Emergency Center which was responsible for the scene injury triage. After reexamination and triage, only 11 cases were defined as critical ill patients. The over-triage rate reached as high as 62.07%. Seventeen patients underwent surgery and 17 patients were admitted to the intensive care unit.</p><p><b>CONCLUSIONS</b>The present pre-hospital system is incomplete and may induce two surges of medical demand. The first one has a much larger number of casualties than predicted but the injury level is mild; while the second one has less wounded but almost all of them are critical patients. The over-triage rate is high. The hospital emergency response can be improved by an effective re-triage and implementation of a hospital-wide damage control.</p>
