Individuals that suffer injury to the spinal cord can result in long-term, debilitating sequelae. Spinal cord injured patients have increased risk for the development of metabolic disease which can further hinder the effectiveness of treatments to rehabilitate the cord and improve quality of life. In the present study, we sought to understand the impact of high-fat diet induced obesity on spinal cord injury (SCI) by examining transcriptome changes in the area of the injury and rostral and caudal to site of damage 12 weeks after injury...

Increased levels of S100A12 and activated matrix metalloproteinase 2/9 (MMP-2/9) produced by human aortic smooth muscle cells (HASMCs) have recently implicated in the development of thoracic aortic disease. In the present study, we investigated the effect of S100A12 on HASMCs and identified the intracellular signal pathways involved by western blot. The results were shown that up-expression of S100A12 in HASMCs induced cell apoptosis and inhibited cell proliferation. Additionally, S100A12 significantly increased the expression of MMP-2, MMP-9 and VCAM-1 in HASMCs at translational levels...

BACKGROUND: Thoracic injuries are a leading cause of death in polytrauma patients. Early diagnosis and treatment are of paramount importance. Whole-body computed tomography (WBCT) has largely replaced traditional imaging techniques such as conventional radiographs and focused computed tomography (CT) as diagnostic tools in severely injured patients. It is still unclear whether WBCT has led to higher rates of diagnosis of thoracic injuries and thus to a change in outcomes. METHODS: In a retrospective study based on the trauma registry of the German Trauma Society (TraumaRegister DGU(®)), we analysed data from 16,545 patients who underwent treatment in 59 hospitals between 2002 and 2012 (ISS ≥ 9)...

Of all the detrimental effects of spinal cord injury (SCI), one of the most devastating is the disruption of the ability to perform functional movement. Very little is known on the recovery of hindlimb joint kinematics after clinically-relevant contusive thoracic lesion in experimental animal models. A new functional assessment instrument, the dynamic feet distance (DFD) was used to describe the distance between the two feet throughout the gait cycle in normal and affected rodents. The purpose of this investigation was the evaluation and characterization of the DFD during treadmill locomotion in normal and T9 contusion injured rats, using three-dimensional (3D) instrumented gait analysis...

Most body wall injuries in small animals are caused by bite wounds or vehicular trauma. Penetrating gunshot wounds are less common. Bite wounds are characterized by massive trauma to the body wall with associated defects, but fewer internal injuries, whereas gunshot wounds are associated with a high number of internal injuries. Vehicular accident injuries are caused by blunt force trauma and can lead to both body wall defects and internal organ damage. Impalement injuries are rare and are typically associated with internal damage...

The safety and efficacy of pharmacologic and cellular transplantation strategies are currently being evaluated in people with spinal cord injury. In studies of people with chronic spinal cord injuries, it is thought that functional recovery will be best achieved when drug or cell therapies are combined with rehabilitation protocols. However, any functional recovery due to the therapy may be confounded by the conditioned state of the body and by training-induced effects on neuroplasticity. For this reason, we sought to investigate the effects of a multi-modal training program on several body systems...

Shoulder pain in young athletes generally is a result of poor sports technique and overuse. A number intrinsic causes of shoulder pain have been identified. Pain may also be referred to shoulder area from cervical spine, neck and chest pathology. Overuse stress injury of the proximal humeral physis is important to recognize early in order to prevent later complications. Shoulder impingement syndrome is a general term used to describe multiple underlying lesions and relatively uncommon in young athletes. In adolescent athletes, glenohumeral instability is an important underlying pathomechanical basis for shoulder pain...

Streptococcus pneumoniae (S. pneumoniae), otherwise known as 'the pneumococcus', is a fascinating microbe that continues to pose a significant problem to public health. Currently there are no specific National Institute for Clinical Excellence (NICE) or British Thoracic Society (BTS) clinical guidelines referring to the treatment of invasive pneumococcal infection. NICE clinical guidelines suggest the use of lytic β-lactam antibiotic regimens for the management of community-acquired pneumonia and bacterial meningitis; infections for which S...

Undesirable exposure of diaphragm to radiation during thoracic radiation therapy has not been fully considered over the past decades. Our study aims to examine the potential biological effects on diaphragm induced by radiation. One-time ionizing irradiation of 10 Gy was applied either to the diaphragmatic region of mice or to the cultured C2C12 myocytes. Each sample was then assayed for muscle function, oxidative stress, or cell viability on days 1, 3, 5, and 7 after irradiation. Our mouse model shows that radiation significantly reduced muscle function on the 5th and 7th days and increased reactive oxygen species (ROS) formation in the diaphragm tissue from days 3 to 7...

Postoperative chylothorax is a relatively rare but potentially fatal complication caused by iatrogenic injury to thoracic duct system, with an incidence ranging from 2 to 4% after major lung surgery or esophagectomy. The pathophysiologic features of chylothorax include dehydration, loss of nutrients and immunological components. Intraopreative prevention is the first step for the management, and treatment options include conservative therapy, percutaneous intervention, and redo-operation. Although the treatment algorithm has not been standardized, chylothorax which is refractory to conservative treatment, or that with high output greater than 1,000 ml/day should be treated aggressively with thoracic duct embolization or redo-operation in a timely fashion...

BACKGROUND: Spinal cord transection is a radical but effective treatment for highly selective cases of symptomatic spinal re-tethering in paraplegic spina bifida patients. Autonomic dysreflexia (AD) is a potentially life-threatening syndrome involving a dysregulated sympathetic discharge reflex commonly seen following cervical and high thoracic spinal cord injury leading to a disconnect between autonomic pathways above and below the lesion that can lead to severe complications including uncontrolled hypertension, bradycardia, stroke, and potentially death...

Spinal cord injury (SCI) is a complex and devastating condition characterized by disruption of descending, ascending, and intrinsic spinal circuitry resulting in chronic neurologic deficits. In addition to limb and trunk sensorimotor deficits, SCI can impair autonomic neurocircuitry such as the motor networks that support respiration and cough. High cervical SCI can cause complete respiratory paralysis, and even lower cervical or thoracic lesions commonly result in partial respiratory impairment. Although electrophrenic respiration can restore ventilator-independent breathing in select candidates, only a small subset of affected individuals can benefit from this technology at this moment...

INTRODUCTION: We report a pure distraction injury of the upper thoracic spine and uncontrolled hyperthermia without an infectious cause. Quad fever appears in the first several weeks to months after a cervical or upper thoracic SCI and is characterized by an extreme elevation in body core temperature beyond 40 °C without an infectious cause. Discriminating between infectious and noninfectious causes is important, and a thorough clinical assessment is required. MATERIALS AND METHODS: A 52-year-old male visited the emergency room complaining of back pain with complete paralysis [American Spinal Injury Association (ASIA) A] of both lower extremities after a pedestrian-motor vehicle accident...
