Path analysis of mediating effect of perceived stress affecting impact of event in rehabilitation patients with traumatic injury / 中国康复理论与实践

ObjectiveTo explore the effect of perceived stress on the impact of event in rehabilitation patients with traumatic injury, and the mediating role of difficulties in emotion regulation, rumination and sleep. MethodsFrom March, 2022 to March, 2023, using the convenient sampling method, a questionnaire survey was conducted on 192 rehabilitation patients with traumatic injury from Southwest Hospital, Xinqiao Hospital and Daping Hospital. Assessment tools included Perceived Stress Scale, Difficulties in Emotion Regulation Scale, Brief Ruminative Response Scale, Self-Rating Scale of Sleep, and Impact of Event Scale-revised. ResultsPerceived stress, difficulties in emotion regulation, rumination, sleep and the impact of event were correlated with each other in rehabilitation patients with traumatic injury (r = 0.447~0.684, P < 0.01). Perceived stress significant positively predicted the impact of event (β = 0.49, P < 0.001), as well as difficulties in emotion (β = 0.70, P < 0.001), rumination (β = 0.21, P < 0.05) and sleep (β = 0.29, P < 0.001). The direct effect of perceived stress on the impact of event was not significant, but it affected the impact of event through seven mediation paths, among which the independent mediation effect size of difficulties in emotion regulation, rumination and sleep accounted for 24.41%, 11.91% and 24.82%, respectively; the chain mediation effect size of difficulties in emotion regulation and rumination accounted for 13.88%, the chain mediation effect size of difficulties in emotion regulation and sleep accounted for 18.08%, the chain mediation effect size of rumination and sleep accounted for 3.17%, and the chain mediation effect size of difficulties in emotion regulation, meditation and sleep accounted for 3.70%. ConclusionPerceived stress affected the impact of event in rehabilitation patients with traumatic injury through the independent mediation and chain mediation of difficulties in emotion regulation, rumination and sleep.

Quantifying Maxillofacial Traumatic Injury for Holistic Management.

Introduction: The maxillofacial region serves many essential functions of human body. Maxillofacial traumatic injury (MFTI) or sometimes called as facial trauma is the injury to the face, jaws and related structures such as head. Hard tissue / soft tissue injury may range from simple nasal bone fracture to gross facial comminution. The complex maxillofacial trauma has the potential to cause facial disfigurement and difficulty in jaw movement. This study focused on relationship between existing scoring systems as the clinical assessment for MFTI, as a tool for predicting prognosis, morbidity, social and psychological impact. Materials and Method: Data collection included demographics, etiology, MFTI clinical parameters, treatment and psychosocial loss. Data was obtained from the medical records, patient interview at each hospital visit and telephonic interviews as required. A predefined question was prepared containing closed and open ended questions and published scales. Results and conclusion: Mandibular fractures were observed in 69% MFTI cases of which 50% were mandibular only fractures. Need for holistic treatment and management approach was observed. Existing widely used FISS score was found to be predictor for few of the parameters only. Other factors required for holistic treatment approach and planning not predictable by FISS score have also been identified.

Informe de caso: Resultado clínico de TOE conservado después de un evento traumático de pie / Case report: Clinical outcome of TOE preserved after Traumatic event of foot

Introduction: Decision making in determining management of post-trauma patient is very important, especially for traumatic in the small bones, fingers and toes. The global predictor to determine the management of retaining or amputating the limb is using the Mangled Extrimity Severity Score (MESS) scoring system, values above 7 are the indication for amputation. The decision maker have to pay attention for the end result of the actions which were performed in the initial management. Material and Methods: One case is reported from Orthopaedic emergency department Hospital in Makassar, South Sulawesi, Indonesia. A 39-year old male with motor vehicle accident trauma at left foot region since 6 hours before admitted to hospital, later was diagnosed with open comminutive fracture shaft proximal phalang of left 5th toe, the Mangled Extrimity Severity Score (MESS) was 8. Patient underwent emergency debridement and retained the toe by performed Open Reduction Internal Fixation (ORIF) K-Wire. Results: This patient has a good clinical outcome by following up 2 weeks and 8 months after surgery by retain the affected side with debridement and Open Reduction Internal Fixation (ORIF) K-Wire. Patient can ambulate normally with full weight bearing, and there is no difficulty to wearing shoe or sandal. Conclusions: Determination of action by retaining the traumatized limb needs to be considered for the good of the patient, but it is necessary to provide informed consent to the patient and family that there will be a possibility of tissue death with the worst possibility of limb amputation

Child injured by suspected catfish (Cetopsis sp. ) bite in river, Humaitá, Amazonas, Brazil

Abstract We present the first recent reported case of traumatic injury caused by catfish in the Americas. Although 66.2% of fish-related injuries occur in the Amazon Region, they are scarcely reported. We report a traumatic injury in a 2-year-old boy who entered Madeira River. The use of traditional methods to treat the injury and his incomplete vaccination history reflect the weakness of the health system. Further, the fact that it was the second time that such an incident had occurred in the locality in 3 weeks during the dry season suggests that this could be a frequent occurrence during this period.

A Retrospective Study To Evaluate The Impact Of Traumatic Dental Injury On Quality Of Life Of Children And Their Parents

An injury to the anterior teeth can affect a perfect smile and thus have an adverse effect on the psychology of the individual. Traumatic injuries to the anterior teeth among the young children are tragic but often an ignored problem. The aim of the study is to determine the impact of traumatic dental injuries to permanent anterior teeth on the quality of life of children of 7–14years of age and their parents. A cross sectional survey was conducted in 25 schools in and around Mangalore South. The study participants included parents of children with age group of 7–14 years. Participants will be informed about the purpose of the study and a questionnaire will be distributed to the children who have undergone traumatic dental injury. The results of this study showed that 94.6% children did not miss school due to traumatic injury but 5.4% children missed the school. Similarly, on evaluating the impact on the parents, 99.1% parents did not leave from work for this same reason. This study shows that there is no impact on the quality of life of the children and their parents. The parents and children should be given awareness on the importance of trauma to the teeth and its management.

Sepsis-related acute kidney injury after traumatic injury / 解放军医学杂志

The mechanisms of traumatic injury-induced acute kidney injury (AKI) are very complicated. Among these mechanisms, sepsis-related AKI is the most harmful and the most difficult to treat. The medical community gave a high priority on this disease, dedicated to raise the level of awareness and treatment through its pathogenesis, early diagnosis ideas and biomarkers, and standardization of treatment. There has been some consensus on the classification of sepsis, AKI, and treatments of antiinfection, fluid resuscitation, renal replacement therapy. A series articles and guidelines have also been published and the survival status of patients have been improved, but many basic and clinical issues are still controversial and need to be answered by further trails. This article focuses on the progress of pathogenesis, diagnosis and treatment about sepsis-related AKI, and tries to raise the understanding level of early diagnosis and standardized treatment of it.

Recognition of Association Between Blood Stasis Syndrome and Traumatic Injury among Doctors of Korean Medicine: A Cross-Sectional Observation Study / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the diagnostic indicators and herbal treatments for blood stasis syndrome (BSS) patients with traumatic injuries and to identify the association between BSS and traumatic injury in Korea.</p><p><b>METHODS</b>Two-hundred and four patients with traumatic injury were recruited from the Gangnam and Daejeon branches of Jaseng Hospital of Oriental Medicine between June 2014 and December 2014. Two independent doctors of Korean medicine (DKMs) determined the diagnosis of BSS or non-BSS based on the subjects signs and symptoms. The scores assigned to BSS symptoms and DKMs' reasons for diagnosing BSS in patients with traumatic injury were investigated. Both medication and herbal prescription records from a 3-month period were collected for all patients diagnosed with BSS by both DKMs.</p><p><b>RESULTS</b>A total of 169 of 204 (82.8%) patients received consistent diagnosis related to BSS by two DKMs. Among them, 54.4% (92 cases) were diagnosed with BSS, and 45.6% (77 cases) were not diagnosed with BSS. DKMs most frequently cited symptoms of recent traumatic injury as justifications for BSS diagnoses, and also selected pain-related indicators such as abdominal pain, sharp pain and nocturnal pain as important reasons in diagnosing BSS. In addition, an inconsistency in the pattern identification theory with respect to traumatic injury was observed. Although only 92 cases (54.4%) of patients were diagnosed with BSS, 77.6% of them were prescribed decoctions for BSS.</p><p><b>CONCLUSIONS</b>DKMs considered traumatic injury could cause BSS, and utilized decoction for BSS in patients with traumatic injury without confirming a diagnosis of BSS because they assumed the main symptoms or pathologies of traumatic injury to be closely related to BSS.</p>

Heterotopic Ossification of the Xiphoid Process after Abdominal Surgery for Traumatic Hemoperitoneum

Heterotopic ossification of the xiphoid process is extremely rare, with only three cases previously reported. However, the surgical pathology for postoperative elongation of the xiphoid process after abdominal surgery has not yet been reported. We report a case of the postoperative elongation of the xiphoid process, 8 years after abdominal surgery for traumatic hemoperitoneum in a 53-year-old man. The patient underwent surgical excision of the elongated mass of the xiphoid process. Histopathology revealed multiple exostoses. Heterotopic ossification can occur after surgical trauma to soft or bone tissue. Surgical excision with primary closure is the treatment of choice for symptomatic heterotopic ossification.

Effects of Potentilla fulgens on the changes made in the retinal damage induced by traumatic head injury / Efectos de Potentilla fulgens en los cambios producidos debido al daño retinal inducido por lesión traumática en la cabeza

Traumatic head injury is a leading cause of mortality and morbidity. As a result of head trauma occurring in the retina of the various biochemical, histological and immunohistochemical effects were investigated. Sprague­Dawley rats were subjected to traumatic brain injury with a weight-drop device using 300 g-1 m weight­height impact. Twenty one rats were divided into three groups, as group 1 (vehicle-treated control), group 2 (vehicle-treated trauma) group 3 trauma + Potentilla fulgens ( P. Fulgens) 400 mg/kg/day, i.p.). Distilled water was used as vehicle. All rats were decapitated 5 days after the induction of trauma, and the protective effects of P. Fulgens were evaluated by histological, immunohistochemical and biochemical analyses. Although further studies are necessary to evaluate the time-and dose-dependent neuroprotective effects of P. Fulgens. Depending on whether trauma inhibits apoptosis of photoreceptor cells, ganglion cells, it is thought that the the support against the degeneration of neural connections can be considered. This study indicates that P.Fulgens is potentially useful for the treatment of eye disorders induced by traumatic brain injury.

El trauma de cráneo es una de las principales causas de morbilidad y mortalidad. Como resultado de un traumatismo craneal, la retina puede sufrir diversos efectos bioquímicos, histológicos e inmunohistoquímicos. Veintiún ratas Sprague-Dawley fueron sometidas a lesión craneal traumática con un dispositivo, de caída de peso, usando un impacto de 300 g-1 m de peso-altura. Las ratas fueron divididas en tres grupos: grupo 1 (control), grupo 2 (traumatismo) y grupo 3 trauma + Potentilla fulgens (400 mg / kg / día, i. p.). Se usó agua destilada como vehículo en todos los grupos. Las ratas fueron decapitadas 5 días después de la inducción del trauma, y se evaluaron los efectos protectores de P. Fulgens mediante análisis histológicos, inmunohistoquímicos y bioquímicos. Es necesario realizar más estudios para evaluar los efectos neuroprotectores, dependientes del tiempo y la dosis, de P. Fulgens. Dependiendo si el trauma inhibe la apoptosis de las células fotorreceptoras, se estima que la disposición de las células ganglionares ayuda contra la degeneración de las conexiones neuronales. P. Fulgens ha demostrado ser efectivo para el tratamiento de los trastornos oculares inducidos por lesión cerebral traumática.

Rol de la endoscopía en la lesión traumática de la vía aérea / Role of endoscopy in traumatic airway injury

Las lesiones del árbol traqueobronquial (aTB) es un evento no frecuente, pero con un alto riesgo de vida. La causa puede ser iatrogénica, secundaria a procedimientos médico y traumática por trauma cerrado o penetrante. Su incidencia no se conoce exactamente. La dificultad para establecer la incidencia de la lesión traumática se debe a que un 30 a 80% de las víctimas de trauma fallecen en el lugar del accidente por las lesiones asociadas. El pronóstico de los pacientes que logran llegar al hospital va a depender esencialmente de las características de la lesión en la vía aérea (VA) y las lesiones asociadas.

Injuries to the tracheobronchial tree (aTB) is an uncommon event, but with a high risk of life. The cause can be iatrogenic, secondary to medical and traumatic procedures by closed or penetrating trauma. Its incidence is not exactly known. The difficulty in establishing the incidence of the traumatic injury is due to the fact that 30 to 80% of trauma victims die at the scene of the accident due to the associated injuries. The prognosis of patients who reach the hospital will depend essentially on the characteristics of the airway (VA) lesion and associated lesions.

Trauma dental e protetor bucal: conhecimento e atitudes em estudantes de graduação em Educação Física / Dental trauma and mouthguard: knowledge and attitudes in Physical Education undergraduates

Resumo Este estudo objetivou avaliar o conhecimento e as atitudes de estudantes de Educação Física de Universidades públicas do Estado do Rio de Janeiro, Brasil, em relação ao traumatismo dentário e uso de protetor bucal. Foram entrevistados 373 graduandos de três universidades públicas do Rio de Janeiro, através de questionário semiestruturado e padronizado. Os dados foram tabulados e analisados (SPSS 16.0), sendo obtida a frequência (%) e a relação dos mesmos (Teste qui-quadrado, p < 0,05). Apenas 3,21% dos entrevistados haviam recebido informação sobre traumatismo dentário e utilização do protetor bucal durante a graduação. Com relação à atitude dos graduandos, responderam corretamente apenas 19,83% a conduta frente a uma avulsão; 54,69% ao manuseio do dente avulsionado e 7,77% ao transporte do dente avulsionado. Ao se comparar essas atitudes em razão do período de graduação (< 5º período ou ≥ 5º período), informações prévias de trauma e experiências prévias de trauma, não se observou diferença significativa (p > 0,05). Tratando de prevenção, 89,81% conheciam o protetor bucal, embora apenas 17,96% o utilizavam durante atividades esportivas. Conclui-se que os alunos não recebem tais informações durante a graduação, mesmo possuindo em sua grade curricular a disciplina de primeiros socorros. Cabe aos cirurgiões dentistas desenvolver ações para que este conhecimento supra as necessidades dos futuros profissionais de educação física.(AU)

Abstract To evaluate the knowledge and attitudes in a group of Brazilian physical education undergraduate students, relative to dental trauma and use of mouthguard. A total of 373 undergraduates from three public universities of Rio de Janeiro were interviewed by means of a semi-structured standardised questionnaire. The data were tabulated and analyzed using the statistical program SPSS, 17.0. Frequency was performed and it was also applied the qui-quadrado (p < 0.05) test, to establish a relation between variables of interest. Only 3.21% of the interviewees had been given information on dental trauma and use of mouth protector during their undergraduate course. With regard to their attitudes, only 19.83% responded correctly about how to act towards a tooth avulsion; 54.69% about how to manage the avulsed tooth, and 7.77% about how to transport the avulsed tooth. By comparing these attitudes in relation to the undergraduate period (before or after the 5th semester), previous information and experience on dental trauma, it was observed no significant difference (p > 0.05). With regard to prevention, 89.81% knew mouthguard although only 17.96% wore it during sport activities. The students were given no information during their undergraduation course, even though the curriculum has the discipline of first aid. The dentist are supposed to develop actions so that such knowledge meets the needs of the future physical education practitioners.(AU)

Use of ultrasound Doppler to determine tooth vitality in a discolored tooth after traumatic injury: its prospects and limitations

When a tooth shows discoloration and does not respond to the cold test or electric pulp test (EPT) after a traumatic injury, its diagnosis can be even more difficult due to the lack of proper diagnostic methods to evaluate its vitality. In these case reports, we hope to demonstrate that ultrasound Doppler might be successfully used to evaluate the vitality of the tooth after trauma, and help reduce unnecessary endodontic treatments. In all three of the present cases, the teeth were discolored after traumatic injuries and showed negative responses to the cold test and EPT. However, they showed distinctive vital reactions in the ultrasound Doppler test during the whole observation period. In the first case, the tooth color returned to normal, and the tooth showed a positive response to the cold test and EPT at 10 wk after the injury. In the second case, the tooth color had returned to its normal shade at 10 wk after the traumatic injury but remained insensitive to the cold test and EPT. In the third case, the discoloration was successfully treated with vital tooth bleaching.

Risk Factors of Past Injuries among of the Sports Climbing Athletes Who Participated in the National Sports Festival / 대한스포츠의학회지

The purpose of this study is to evaluate the risk factors regarding the injuries from sports climbing through an epidemiologic study. We performed a questionnaire survey on sports climbers who participated in the 93th Annual Sports Festival in Daegu, in October 2012. Sixty-nine climbers (male: 57, female: 12) responded to the survey. The t-test was used for comparisons of the incidence of injury, according to sex and career. The multiple linear regression analysis and the logistic regression analysis were used for the evaluation of risk factors that affected the occurrence of injury. Overall, 58 (84.06%) climbers had history of injury. The incidences of climbing related injuries were higher than the incidences of cross-training related injuries. However, there were no significant difference (p=0.680). Also, there was no significant difference between males and females (p=0.467), and professionals and amateurs (p=0.076). Fifty (72.46%) out of 69 climbers had history of traumatic injuries, and 40 (57.97%) climbers had history of overuse injuries. Significant risk factors for traumatic injuries are leading (odds ratio, OR=17.854), speed (OR=45.246), and bouldering (OR=13.595). Significant risk factors for overuse injuries are leading (OR=23.252) and bouldering (OR=41.260). Significant risk factors for middle phalanx injuries, which happens most frequently in climbing related injuries, are leading (OR=20.625) and bouldering (OR=25.756). For traumatic injuries, leading, speed, and bouldering are prone to cause injuries, and leading and bouldering are significant factors for overuse injuries. Therefore, it is considered that the systematic organized training can help reduce the incidence of injury.

Risk Factors of Past Injuries among of the Rowing Athletes Who Participated in the National Sports Festival / 대한스포츠의학회지

The purposes of this study were basic data collection and evaluation of the risk factors regarding rowing injuries through an epidemiologic study. We performed a questionnaire survey from rowers who participated in the 91th Annual Sports Festival in Jinju, Gyeongnam, in October 2010. 145 rowers (male: 84, female: 61) responded to the survey. The t-test was used for comparisons for the type of injury, age, and gender. The multiple linear regression analysis and the logistic regression analysis was used for the evaluation of risk factors. Overall, 100 (69.0%) rowers had a history of injury. The incidence of overuse injuries was significantly higher than the incidence of traumatic injuries (2.07+/-2.59/rower vs. 1.46+/-2.08/rower, p=0.027). The incidence of injuries for the adult group was significantly higher than those in the youth group (4.42+/-4.45/rower vs. 2.61+/-3.63/rower, p=0.008). There was no significant difference between males and females (3.85+/-4.33/rower vs. 3.08+/-3.87/rower, p=0.275). Also, the incidence of cross-training related injury was significantly higher in traumatic injuries rather than in overuse injuries (0.92+/-1.54/rower vs. 0.5+/-1.07/rower, p=0.008). In addition, rowing injuries were more related with overuse injuries. Risk factors regarding overall rowing injuries were training time, and training using stairs. Traumatic injuries were related with diverse cross-training and time spent cross-training. Therefore, in order to reduce the incidence of rowing injuries, time and the number of cross-training sessions should be reduced. Moreover, highly risky training such as using stairs should be replaced with other low risk training methods.

Sialocele: An unusual case report and its management.

A post traumatic parotid sialocele is an acquired lesion that arises from extravasation of saliva into glandular or periglandular tissues secondary to disruption of the parotid duct or parenchyma. Facial trauma and surgery in the parotid region are the most common causes of this rare condition. This paper presents an unusual incidence of post traumatic parotid sialocele after Le-Fort II fracture reduction and its management by relatively simple and cost-effective technique which can be carried out in routine dental surgery suite. The results achieved justify our recommendation of scalp vein cannula for the treatment of sialocele in clinical practice.

Apoptosis neuronal: la diversidad de señales y de tipos celulares / Neuronal apoptosis: signal and cell diversity

La muerte celular programada es un evento fisiológico durante el desarrollo. En el encéfalo y la médula espinal, este proceso determina el número y la localización de los diferentes tipos celulares. En el sistema nervioso del adulto, la muerte celular programada o apoptosis está más restringida, pero puede jugar un papel determinante en enfermedades crónicas o agudas. Al contrario de otros tejidos en los cuales la apoptosis está documentada ampliamente desde el punto de vista morfológico, en el sistema nervioso central la evidencia en este sentido es escasa. A pesar de esto, existe consenso acerca de la activación de diferentes sistemas de señalización apoptótica. En el presente artículo se intenta resumir las principales vías de señalización apoptótica identificadas en el tejido nervioso. Considerando que las vías apoptóticas son múltiples, los tipos neuronales diversos y especializados y que la respuesta neuronal a la lesión y la supervivencia dependen del contexto de la célula en el tejido (preservación de la conectividad, integridad glial y matriz extracelular, flujo sanguíneo y disponibilidad de factores tróficos), lo que es relevante en el proceso apoptótico en un sector del cerebro puede no serlo en otro.

Programmed cell death occurs as a physiological process during development. In the brain and spinal cord this event determines the number and location of the different cell types. In adulthood, programmed cell death or apoptosis is more restricted but it may play a major role in different acute and chronic pathological entities. However, in contrast to other tissues where apoptosis has been widely documented from a morphological point of view, in the central nervous system complete anatomical evidence of apoptosis is scanty. In spite of this there is consensus about the activation of different signal systems associated to programmed cell death. In the present article we attempt to summarize the main apoptotic pathways so far identified  in nervous tissue. Considering that apoptotic pathways are multiple, the neuronal cell types are highly diverse and specialized and that neuronal response to injury and survival depends upon tissue context, (i.e., preservation of connectivity, glial integrity and cell matrix, blood supply and trophic factors availability) what is relevant for the apoptotic process in a sector of the brain may not be important in another.
