This study examined the content of self-defining autobiographical memories in different identities in patients with Dissociative Identity Disorder (DID) and comparison groups of patients with PTSD, healthy controls, and DID simulators. Consistent with the DID trauma model, analyses of objective ratings showed that DID patients in trauma identities retrieved more negative and trauma-related self-defining memories than DID patients in avoidant identities. Inconsistent with the DID trauma model, DID patients' self-rated trauma-relatedness of self-defining memories and future life goals did not differ between trauma identities and trauma avoidant identities...

Determining the mechanical properties of brain tissues is essential in such cases as the surgery planning and surgical training using virtual reality based simulators, trauma research and the diagnosis of some diseases that alter the elastic properties of brain tissues. Here, we suggest a protocol to measure the temperature-dependent elastic properties of brain tissues in physiological saline using the shear wave elastography method. Experiments have been conducted on six porcine brains. Our results show that the shear moduli of brain tissues decrease approximately linearly with a slope of -0...

Traumatic brain injury is the leading cause of death and severe disability for young people and a major public health problem for elderly. Many patients with intracranial bleeding are treated too late, because they initially show no symptoms of severe injury and are not transported to a trauma center. There is a need for a method to detect intracranial bleedings in the prehospital setting. In this study, we investigate whether broadband microwave technology (MWT) in conjunction with a diagnostic algorithm can detect subdural hematoma (SDH)...

BACKGROUND: Junctional hemorrhage (i.e., between the trunk and limbs) are too proximal for a tourniquet and difficult to compress. These hemorrhages are responsible for 20% of preventable deaths by bleeding on the battlefield. The majority of these involve the groin area. Devices allowing a proximal compression for arterial axes have been recently developed. OBJECTIVE: The purpose of this study was to compare the use of two junctional- tourniquet models, the Combat Ready Clamp (CRoC®) and the SAM® Junctional Tourniquet (SJT), in simulated out-of-hospital trauma care when tourniquets were ineffective to stop the arterial flow...

OBJECTIVES: To develop a novel assessment tool for trainees-led trauma resuscitation. Assess psychometric properties of the proposed tool. Evaluate feasibility and utility of the tool. INTRODUCTION: Trauma resuscitation is a structured and complex process involving unique sets of skills. There is currently no published structured formative evaluation tool for trauma trainees. Therefore, many trauma trainees rely upon limited, unstructured feedback on their performance...

We evaluated the effects of chitosan membrane, a highly absorbable and viscous material, in the prevention of intra-articular adhesions after anchoring of the disc in the temporomandibular joints (TMJ) of six adult goats (12 joints). To simulate anterior displacement of the disc and TMJ trauma, we cut off the retrodiscal attachment and damaged the surface of the condylar bone, then randomly divided the goats into two groups: the control group (n=2) and the experimental group (n=4). In the experimental group we covered the condylar surfaces on both sides of the animals with chitosan membranes...

Repetitive mild traumatic brain injury (rmTBI), resulting from insults caused by an external mechanical force that disrupts normal brain function, has been linked to the development of neurodegenerative diseases, such as chronic traumatic encephalopathy and Alzheimer disease; however, neither the severity nor frequency of head injury required to trigger adverse behavioral outcomes is well understood. In this study, the administration of 30 head impacts using two different weights to lightly anesthetized, completely unrestrained mice established a paradigm that simulates the highly repetitive nature of sports- and military-related head injury...

This paper investigates multiple imputation methods for regression models with interacting continuous and binary predictors when continuous variable may be missing. Usual implementations for parametric multiple imputation assume a multivariate normal structure for the variables, which is not satisfied for a binary variable nor its interaction with a continuous variable. To accommodate interactions, missing covariates are multiply imputed from conditional distribution in a manner consistent with the joint model...

INTRODUCTION: The high prevalence of deep vein thrombosis (DVT) reported in prospective studies and the unreliability of clinical diagnosis mandates prospective screening for DVT in burn patients. Our study seeks to compare D-dimer and Doppler ultrasound (DUS) in search for a practical, inexpensive and a reliable screening tool. METHODS: One hundred burn patients (inclusion criteria: 30-60% TBSA burn, >18 years of age, admitted within 48h of burn) were computer randomized into two equal groups...

A battery-operated active cooling/heating device was developed to maintain thermoregulation of trauma victims in austere environments while awaiting evacuation to a hospital for further treatment. The use of a thermal manikin was adopted for this study in order to simulate load testing and evaluate the performance of this novel portable active cooling/heating device for both continuous (external power source) and battery power. The performance of the portable body temperature conditioner (PBTC) was evaluated through cooling/heating fraction tests to analyze the heat transfer between a thermal manikin and circulating water blanket to show consistent performance while operating under battery power...

BACKGROUND: A lateral approach with open reduction and internal fixation with a plate is a very effective technique for the majority of distal fibular fractures. However, this open approach for ankle fixation may be complicated by wound dehiscence and infection, especially in high-risk patients. An alternative to plating is an intramedullary implant, which allows maintenance of length, alignment, and rotation and which allows for decreased soft tissue dissection. While there has been clinical data suggesting favorable short-term outcomes with these implants, there is no current biomechanical literature investigating this technology in this particular fracture pattern...

INTRODUCTION: Leadership skills are described by the American College of Surgeons' Advanced Trauma Life Support (ATLS) course as necessary to provide care for patients during resuscitations. However, leadership is a complex concept, and the tools used to assess the quality of leadership are poorly described, inadequately validated, and infrequently used. Despite its importance, dedicated leadership education is rarely part of physician training programs. The goals of this investigation were the following: 1...

BACKGROUND: Urinary catheter insertion is a common procedure performed in hospitals. Improper catheterization can lead to unnecessary catheter-associated urinary tract infections and urethral trauma, increasing patient morbidity. To prevent such complications, guidelines were created on how to insert and troubleshoot urinary catheters. As nurses have an increasing responsibility for catheter placement, resident responsibility has shifted to more complex scenarios. This study examines the clinical decision-making skills of surgical residents during simulated urinary catheter scenarios...

Careful examination of the skin and soft tissues is a routine part of the forensic autopsy to identify and characterise traumatic lesions. Three cases are reported where benign vascular lesions presented as bruises. In case 1, a 44-year-old man with a history of epilepsy was found dead on the floor. Dissection of the neck revealed a haemorrhagic area 15 mm × 1.5 mm, deep to the left thyrohyoid muscle. In case 2, an 87-year-old man was found dead with a plastic bag over his head attached to an opened cylinder of nitrogen gas...
