"Defense" type wounds are sustained when a victim is attempting to ward off an attacker, or a weapon. A 39-year-old woman is reported who was found deceased with incised wounds to the dorsa of both hands that resembled defense wounds. Examination of the flexor surfaces of both wrists, however, revealed horizontal incised wounds typical of self-infliction. Perfusion of the subclavian arteries produced leakage of water from peripheral veins within wounds on both hands and the right wrist. Death was due to exsanguination from incised wounds of the hands and right wrist; manner suicide...

BACKGROUND: Liver failure results in hyperammonaemia, impaired regulation of cerebral microcirculation, encephalopathy and death. However, the key mediator that alters cerebral microcirculation remains unidentified. In this study we show that topical ammonium significantly increases periarteriolar adenosine tone on the brain surface of healthy rats and is associated with a disturbed microcirculation. METHODS: Cranial windows were prepared in anaesthetized Wistar rats...

INTRODUCTION: Damage control laparotomy with vacuum assisted closure (VAC) is used for selective cases in trauma. In liver transplantation, VAC has also been applied for management of intra-operative hemorrhage. The primary objective was to evaluate peri-operative blood loss and blood product utilization in VAC compared to primary abdominal closure (PAC) at the index transplant operation. METHODS: Retrospective review of all adults undergoing deceased donor liver transplantation (2007-2011) at a single center tertiary care institution...

Conditions of systemic stress can lead to increased reactive oxygen species production, mitochondrial dysfunction, systemic inflammation, and multiorgan dysfunction. Triphenylphosphonium (TPP+) is a lipophilic cation used to target therapeutics to mitochondria. We sought to determine the effects of TPP+ on mitochondrial integrity. Male rats were anesthetized and TPP+ (5 mg/kg) or vehicle (saline) was administered intravenously 30-minutes after anesthesia initiation and intraperitoneally (20 mg/kg) 60-minutes later...

Neurologic deficit subsequent to cardiac surgery remains a cause of postoperative morbidity and mortality. Although myriad risk factors for postoperative cognitive decline have been identified, their individual influence remains undefined. Although less emphasis is now placed on the heart lung machine as the major source of postoperative cognitive decline, the conduct of cardiopulmonary bypass and, in particular, the management of the bypass circuit remain key to patient safety. We present a case of inadvertent intraoperative exsanguination of a patient following open heart surgery for implantation of a left ventricular assist device...

The gastrointestinal tract is a common site for the occurrence of non-Hodgkin's lymphoma (NHL). NHL with gastrointestinal lesions may lead to clinically relevant intestinal complications such as obstruction, perforation, and exsanguination during the course of the disease. Consequently, patients with NHL are often examined by means of upper and lower gastrointestinal endoscopy at the initial visit. There are no clear guidelines regarding which patients should undergo capsule endoscopy (CE) and balloon enteroscopy for detecting small intestinal lesions...

We hypothesized that abomasal infusion of glucose would promote de novo fatty acid biosynthesis from glucose in vitro in bovine intramuscular (i.m.) and subcutaneous (s.c.) adipose tissues to a greater extent than ruminal infusion of acetate, propionate, or glucose. Angus crossbred steers (n = 24), 22 mo of age, were fitted with ruminal cannulas, and steers were adapted to another corn/sorghum finishing diet over a 2-wk period while recovering from the placement of the cannulas. After the adaptation period, the steers were fed the second finishing diet at 130% of their voluntary intake and were infused with isocaloric amounts (3...

Damage control surgery (DCS) began as an adjunct approach to hemorrhage control, seeking to facilitate the body's innate clotting ability when direct repair or ligation was impossible, but it has since become a valuable instrument for a broader collection of critically ill surgical patients in whom metabolic dysfunction is the more immediate threat to life than imminent exsanguination. Modern damage control is a strategy that combines the principles of DCS with those of damage control resuscitation. When used correctly, damage control may improve survival in previously unsalvageable patients; when used incorrectly, it can subject patients to imprudent risk and contribute to morbidity...

In this study, we present two cases of sudden deaths of people with end-stage kidney with arteriovenous fistulas for long-term hemodialysis treatment. This procedure is associated with a number of known complications. While stenosis, thrombosis, and infection are well known, lethal hemorrhage from arteriovenous fistula is much less commonly encountered. Inspection of the bodies at the scene of the death by a medical examiner suggested that the deaths were due to exsanguination. Autopsies revealed visible defects on the front wall of the arteriovenous fistulas...

BACKGROUND: Difficult-airway prediction tools help identify optimal airway techniques, but were derived in elective surgery patients and may not be applicable to emergency rapid sequence intubation (RSI). The HEAVEN criteria (Hypoxemia, Extremes of size, Anatomic abnormalities, Vomit/blood/fluid, Exsanguination, Neck mobility issues) may be more relevant to emergency RSI patients. OBJECTIVE: To validate the HEAVEN criteria for difficult-airway prediction in emergency RSI using a large air medical cohort...

GATA transcription factor is a family of DNA-binding proteins that can recognize and bind to sequence of (A/T) GATA (A/G). In the present study, a GATA-like protein (named as EsGLP) was characterized from Eriocheir sinensis, including an 834 bp full length open reading frame of EsGLP, encoding a polypeptide of 277 amino acids. The deduced amino acid sequence of EsGLP contained one conserved GATA-type zinc finger of the form Cys-X2-Cys-X17-Cys-X2-Cys, with four cysteine sites. The EsGLP mRNA transcripts were mainly detected in the hematopoietic tissue, hepatopancreas and gonad...

The mechanism that maintains a stable blood flow in the brain despite changes in cerebral perfusion pressure (CPP), and therefore guaranties a constant supply of oxygen and nutrients to the neurons, is known as cerebral autoregulation (CA). In a certain range of CPP, blood flow is mediated by a vasomotor adjustment in vascular resistance through dilation of blood vessels. CA is known to be impaired in diseases like traumatic brain injury, Parkinson's disease, stroke, hydrocephalus and others. If CA is impaired, blood flow and pressure changes are coupled and the oxygen supply might be unstable...

Successful replantation of distal digital segments necessitates the establishment of sufficient outflow to minimize congestion and progressive tissue necrosis. In cases where only arterial anastomosis is feasible, an artificial outlet must be provided to maintain physiological requirements until microvenous circulation regenerates. This can be accomplished using any number of "exsanguination techniques" designed to facilitate egress through ongoing passive blood loss. Although reportedly effective, these measures are imprecise and carry a substantial risk of infection, scarring, and/or uncontrolled hemorrhage...

PURPOSE: Despite using a multidisciplinary treatment approach, the mortality rate of patients with hemodynamic instability from severe pelvic fractures is still 40-60%. We evaluated the improvement of outcomes in this patient population after the establishment of a regional trauma center in Korea. METHODS: We retrospectively reviewed the medical charts of 50 patients with hemodynamic instability due to pelvic fractures between March 2011 and November 2016. Patients were divided into two groups: the pre-trauma center (PTC) group (n = 23) and trauma center (TC) group (n = 27)...

BACKGROUND: Digit tourniquets are widely used in the operating room and even more often in the emergency department to allow the exploration of injuries. A rolled surgical glove finger or silicone catheter placed at the base of the digit is a common method. However, rolled glove tourniquets are easily forgotten under the dressing and may then cause ischaemia, which may require amputation. Silicone catheters are expensive single-use devices that may fail to provide effective exsanguination and must be removed by cutting, which may result in skin lesions...

REVIEW

Massive hemoptysis is a life-threatening condition often defined as coughing up 300-600mL of blood in 24 hours in an adult, or >8mL/kg in 24 hours in a child. Although the definition is controversial, one should view massive hemoptysis as any volume of expectorated blood that can cause respiratory failure. This is because mortality in the setting of hemoptysis is usually associated with asphyxiation, rather than exsanguination. Massive hemoptysis accounts for only about 5% of cases of hemoptysis, but when treated conservatively, has a reported mortality rate between 50% and 85%...

A contribution of pulmonary blood distension to alveolar opening was first proposed more than 100 years ago. To investigate the contribution of blood distension to lung mechanics, we studied control mice (normal perfusion), mice after exsanguination (absent perfusion) and mice after varying degrees of parenchymal resection (supra-normal perfusion). On inflation, mean tracheal pressures were higher in the bloodless mouse (4.0 ± 2.5 cm H2O); however, there was minimal difference between conditions on deflation (0...

Objective Alveolar macrophages play a key role in the development and resolution of acute respiratory distress syndrome (ARDS), modulating the inflammatory response and the coagulation cascade in lungs. Anti-coagulants may be helpful in the treatment of ARDS. This study investigated the effects of nebulized heparin on the role of alveolar macrophages in limiting lung coagulation and inflammatory response in an animal model of acute lung injury (ALI). Methods Rats were randomized to four experimental groups...

Cyclin-dependent kinases (CDKs), a family of cell cycle-related serine/threonine kinases, participate in various biological processes, and play crucial roles in the innate immunity. In the present study, a CDK2 (designed as EsCDK2) with a serine/threonine protein kinase catalytic domain was identified from Chinese mitten crab (Eriocheir sinensis). The full-length cDNA sequence of EsCDK2 was of 2405 bp with an open reading frame (ORF) of 909 bp. EsCDK2 shared 66%-81% sequence similarities with previously identified CDK2s...

The purpose of this study was to test if associations exist between plasma indicators of acute and chronic stress and lamb loin Warner Bratzler Shear Force (WBSF). Blood was collected at exsanguination from 2877 lambs from the Meat and Livestock Genetic Research flock with a suite of indicators analysed. Loin (M. longissimus lumborum) WBSF was measured after 5days aging. Plasma indicators of stress did not relate to WBSF, however a positive association was found between WBSF and kill order, indicating that immediate pre-slaughter factors may be causing reduced tenderness in lamb...
