Spreading depolarizations (SDs) occur spontaneously in the cerebral cortex of subarachnoid hemorrhage, stroke or traumatic brain injury patients. Accumulating evidence prove that SDs exacerbate focal ischemic injury by converting zones of the viable but non-functional ischemic penumbra to the core region beyond rescue. Yet the SD-related mechanisms to mediate neurodegeneration remain poorly understood. Here we show in the cerebral cortex of isoflurane-anesthetized, young and old laboratory rats, that SDs propagating under ischemic penumbra-like conditions decrease intra and- extracellular tissue pH transiently to levels, which have been recognized to cause tissue damage...

Hanging is a common method of suicide that is being reported more frequently in many countries. Several complications including injuries to the cervical spine, neck vessels, and brain can occur after attempted suicide by hanging. There are only a few reports of brain computed tomography and magnetic resonance imaging of hanging victims. The most common abnormality was diffuse cerebral edema. A subarachnoid hemorrhage is an atypical complication by suicidal hanging. We report a case of a female patient who presented to an emergency department with altered mental status after attempting suicide by incomplete hanging...

Uncontrolled massive bleeding with subsequent derangement of the coagulation system is a major challenge in the management of both surgical and seriously injured patients. Under physiological conditions activators and inhibitors of coagulation regulate the sensitive balance between clot formation and fibrinolysis. In some cases, excessive and diffuse bleeding is caused by systemic activation of fibrinolysis, i. e. hyperfibrinolysis (HF). Uncontrolled HF is associated with a high mortality. Polytrauma patients and those undergoing surgical procedures involving organs rich in plasminogen proactivators (e...

Trauma-induced acute kidney injury (AKI), such as after hemorrhagic shock (HS) or burn, remains a significant problem in the intensive care unit and is associated with increased mortality. The pathophysiology that drives AKI post-trauma is multi factorial, and includes both inflammatory and metabolic alterations. Identifying the systemic profile that contributes to AKI is crucial not only for early diagnosis, but also for identifying treatments that improve kidney function and maintaining long-term patient health...

BACKGROUND: Little is known about the long-term course of headache in patients with moderate-to-severe headache due to traumatic brain injury (TBI). We evaluated the course of headache in patients with moderate-to-severe headache due to mild TBI. METHODS: Since September 2009, patients with TBI prospectively rated their headache using a numeric rating scale (NRS). From the database containing 935 patients with TBI between September 2009 and December 2013, 259 patients were included according to following criteria: (1) newly onset moderate-to-severe headache (NRS ≥ 4) due to head trauma; (2) age ≥ 15 years; (3) Glasgow Coma Scale ≥ 13; (4) transient loss of consciousness ≤ 30 min; and (5) radiographic evaluation, such as computed tomography or magnetic resonance image...

We present the spontaneous causes of mortality for 137 chimpanzees (Pan troglodytes) over a 35-year period. A record review of the pathology database was performed and a primary cause of mortality was determined for each chimpanzee. The most common causes of mortality were as follows: cardiomyopathy (40% of all mortalities), stillbirth/abortion, acute myocardial necrosis, chimpanzee-induced trauma, amyloidosis, and pneumonia. Five morphologic diagnoses accounted for 61% of mortalities: cardiomyopathy, hemorrhage, acute myocardial necrosis, amyloidosis, and pneumonia...

BACKGROUND: In Japan, the number of hemodialysis patients increases every year, along with the average age of this patient population. Further, certain complications of hemodialysis make the care of traumatic head injury(THI)patients particularly difficult. OBJECTIVE: This study was aimed at investigating the occurrence of and risk factors for post-traumatic seizures in hemodialysis patients with a history of THI, and determining patient outcomes. METHODS: Subjects were selected from patients who were admitted to Yaizu Municipal Hospital in Shizuoka, Japan for traumatic intracranial hemorrhage(TICH)...

REVIEW
Babita Gupta, Neha Garg, Rashmi Ramachandran
The priority in the management of patients with traumatic hemorrhagic shock is to control the bleeding with simultaneous volume resuscitation to maintain adequate tissue perfusion. Fluid replacement remains the mainstay of initial resuscitation in hemorrhagic shock. Traditionally, vasopressors are contraindicated in the early management of hemorrhagic shock due to their deleterious consequences, although vasopressors may have a role in resuscitation when vasoplegic shock ensues and blood pressure cannot be maintained by fluids alone...

Therapeutic polymers have the potential to improve the standard of care for hemorrhage, or uncontrolled bleeding, as synthetic hemostats. PolySTAT, a fibrin-crosslinking peptide-polymer conjugate, has the capacity to rescue fibrin clot formation and improve survival in a model of acute traumatic bleeding. PolySTAT consists of a synthetic polymer backbone to which targeting fibrin-binding peptides are linked. For translation of PolySTAT, the optimal valency of peptides must be determined. Grafting of fibrin-binding peptides to the poly(hydroxyethyl methacrylate)-based backbone was controlled to produce peptide valencies ranging from 0 to 10 peptides per polymer...

BACKGROUND: Hemorrhage is a major cause of early mortality following a traumatic injury. The progression and consequences of significant blood loss occur quickly as death from hemorrhagic shock or exsanguination often occurs within the first few hours. The mainstay of treatment therefore involves early identification of patients at risk for hemorrhagic shock in order to provide blood products and control of the bleeding source if necessary. The intended scope of this review is to identify and assess combinations of predictors informing therapeutic decision-making for clinicians during the initial trauma assessment...

Andrew M Choo, Patrick C Schottel, Andrew R Burgess
Scapulothoracic dissociation is a rare, potentially limb- and life-threatening injury of the shoulder girdle. The injury is characterized by lateral displacement of the scapula resulting from traumatic disruption of the scapulothoracic articulation. The typical physical examination findings consist of substantial swelling of the shoulder girdle, along with weakness, numbness, and pulselessness in the ipsilateral upper extremity. Radiographic evaluation includes measurement of the scapular index on a nonrotated chest radiograph and assessment for either a distracted clavicle fracture or a disrupted acromioclavicular or sternoclavicular joint...

Tearing of the parasagittal bridging veins (BVs) is thought to be a source of extra-axial hemorrhage (EAH) associated with abusive traumatic brain injuries (TBIs) in children. However, the pediatric BV mechanical properties are unknown. We subjected porcine adult, porcine newborn, and human infant BVs to either a low rate pull to failure, a high rate pull to failure, or 30 s of cyclic loading followed by a pull to failure. An additional subset of human infant BVs was examined for viscoelastic recovery between two cycling episodes...

The present article was designed to report the results of the analysis of the cases of traumatic and spontaneous ruptures of the organs affected by the tumours based on the original observations and the literature data. It is shown that the probability of the tumour rupture depends on its histological type, localization, the size, and the distance from the capsule of the affected organ, the degree of involvement of the major blood vessels, the severity of the necrotic changes, the presence of cysts in the neoplasm, and the regimens of radio- and chemotherapy...

Paolo Alboni, Nicola Stucci, Elena Cojocaru, Andrea Ungar
At present, the efficacy and safety of anticoagulants, warfarin, or new oral anticoagulants in frail patients remain unknown, as these patients have largely been excluded from both randomized trials and "real-world" studies; as a result, the guidelines do not provide guidance for the management of this population. Frail patients with atrial fibrillation (AF) are significantly less likely to receive oral anticoagulants compared to their nonfrail counterparts; is that an expression of reasonable prudence or malpractice? In this regard, some aspects of physical frailty should be considered: (i) increased vulnerability to stressors, including pharmacological agents with potential severe adverse effects; (ii) frail elderly patients are at high risk of falls and, therefore, of severe traumatic hemorrhages on oral anticoagulation; (iii) frail patients are more likely to have complications during intercurrent affections, potentially responsible for hemorrhages...

A man in his late forties had lived as a recluse for more than ten years. He was found dead in his room. At autopsy, subarachnoid hemorrhage (SAH) was detected at the base of the brain, which weighed 1333 g. The cerebellar tonsil was swollen. The cerebral ventricle was enlarged and filled with blood. A hematoma was observed in the upper part of the left side of the cerebellar hemisphere. The location and size of SAH in this case indicated that the rupture of a cerebral aneurysm (CA) had occurred; however, CA was not detected...

BACKGROUND: Traumatic cardiac arrest studies have reported improved survival rates recently, ranging from 1.7-7.5%. This population-based nationwide study aims to describe the epidemiology, interventions and outcomes, and determine predictors of survival from out-of-hospital traumatic cardiac arrest (OHTCA) in Qatar. METHODS: An observational retrospective population-based study was conducted on OHTCA patients in Qatar, from January 2010 to December 2015. Traumatic cardiac arrest was redefined to include out-of-hospital traumatic cardiac arrest (OHTCA) and in-hospital traumatic cardiac arrest (IHTCA)...
