Described herein is the utilization of the hospital's Emergency Operations Plan and incident command structure to mitigate damage caused by the sudden loss of the heating, ventilation, and air conditioning system within the entire operating room suite. The ability to ameliorate a devastating situation that occurred during working hours at a busy Level II trauma center can be ascribed to the dedication of the leadership and clinical teams working seamlessly together. Their concerted efforts were augmented by adherence to an established protocol that had been thoroughly substantiated and practiced during numerous training simulations...

In recent research, microwave sensors have been used to follow up the recovery of lower extremity trauma patients. This is done mainly by monitoring the changes of dielectric properties of lower limb tissues such as skin, fat, muscle, and bone. As part of the characterization of the microwave sensor, it is crucial to assess the signal penetration in in vivo tissues. This work presents a new approach for investigating the penetration depth of planar microwave sensors based on the Split-Ring Resonator in the in vivo context of the femoral area...

Bone responds to mechanical stimulus and a range of pre-existing finite element models have been suggested to reproduce the internal physiological structure of bone. Inflammation effects are not included in these models, yet inflammation is a key component of bone repair in trauma. Therefore, a model is proposed and tested here that extends these methods to include parameters that could be considered to represent the behaviour of bone remodelling when influenced by inflammation. The proposed model regulates remodelling based on findings from recent studies into the nature of heterotopic ossification, the formation of heterotopic bone, which have revealed information about the nature of bone after high levels of trauma...

The aim of this article is to describe the role of second-level imaging techniques after an initial ultrasonography evaluation in the assessment of scrotal diseases. While ultrasonography remains central as the primary imaging modality for the evaluation of pathologic conditions of the scrotum, the role of magnetic resonance imaging continues to evolve: it can actually be valuable as a problem-solving tool when sonographic findings are equivocal or inconclusive. Magnetic resonance imaging of the scrotum may provide accurate detection and characterization of scrotal diseases, well depicting the precise location of scrotal masses (intratesticular or extratesticular) and reliably characterizing benign conditions simulating neoplastic processes, thus preventing unnecessary radical surgery...

A transverse-plane hyperelastic micromechanical model of brain white matter tissue was developed using the embedded element technique (EET). The model consisted of a histology-informed probabilistic distribution of axonal fibers embedded within an extracellular matrix, both described using the generalized Ogden hyperelastic material model. A correcting method, based on the strain energy density function, was formulated to resolve the stiffness redundancy problem of the EET in large deformation regime. The model was then used to predict the homogenized tissue behavior and the associated localized responses of the axonal fibers under quasi-static, transverse, large deformations...

Central nervous system (CNS) diseases can cause a series of neuronal lesions, which may be improved by the anti-apoptotic neuroprotection of transforming growth factor-beta 1 (TGF-β1). In neurons, L-type Ca2+ channels (LTCC) are mainly composed of Cav1.2 subunits. Given the implication of TGF-β1 in numerous CNS diseases, we examined the neuroprotective effects of TGF-β1 on the Cav1.2 channel in the CNS. To simulate acute mechanical traumatic brain injury (TBI), we used a needle to create parallel scratches across plates, which were cultured for 9 h...

Trauma care at an accident site is of great importance for patient survival. The purpose of the study was to observe the compliance of ambulance nurses with the Prehospital Trauma Life Support (PHTLS) concept of trauma care in a simulation situation. The material consisted of video recordings in trauma simulation and an observation protocol was designed to analyze the video material. The result showed weaknesses in systematic exam and an ineffective use of time at the scene of injury. Development of observation protocols in trauma simulation can ensure the quality of ambulance nurses' compliance with established concepts...

As animal models fall out of favor, there is demand for simulators to train medical personnel in the management of trauma and hemorrhage. Realism is essential to the development of simulators for training in the management of trauma and hemorrhage, but is difficult to achieve because it is difficult to create models that accurately represent bleeding organs. We present a simulation platform that uses real-time mathematical modeling of hemodynamics after hemorrhage and trauma and visually represents the injury described by the model...

OBJECTIVES: The military uses "just-in-time" training to refresh deploying medical personnel on skills necessary for medical and surgical care in the theater of operations. The burden of pediatric care at Role 2 facilities has yet to be characterized; pediatric predeployment training has been extremely limited and primarily informed by anecdotal experience. The goal of this analysis was to describe pediatric care at Role 2 facilities to enable data-driven development of high-fidelity simulation training and core knowledge concepts specific to the combat zone...

Mucormycosis of the scalp is a rare cutaneous presentation of the disease. It is also an unusual infection in children. We present the case of a 4-year-old girl with acute lymphoblastic leukemia, who presented with atypical cutaneous mucormycosis simulating an ecthyma gangrenosum lesion. Risk factors for the infection are diabetes, neoplastic diseases, immunosuppression in organ transplant recipients, and neutropenia. The cutaneos forms have been associated with trauma, burns and surgical wounds. First line treatment is amphotericin B...
