Severe trauma initiates a systemic inflammatory cascade and that involves early activation of complement and cleavage of C5 into C5a (anaphylatoxin) and C5b (C5b-9 membrane attack complex). We examined activation of C5 in non-human primate (NHP) models of hemorrhagic shock. Blood plasma concentrations of C5b-9 were significantly increased in NHPs in response to hemorrhage alone and were further increased with the addition of tissue trauma. The onset of increased C5 cleavage was accelerated in NHPs that experienced decompensated poly-traumatic hemorrhagic shock...

BACKGROUND: Recognizing patients at risk for pulmonary complications (PC) is of high clinical relevance. Migration of polymorphonuclear leukocytes (PMN) to inflammatory sites plays an important role in PC, and is tightly regulated by specific chemokines including interleukin (IL)-8 and other mediators such as leukotriene (LT)B4. Previously, we have reported that LTB4 indicated early patients at risk for PC after trauma. Here, the relevance of LTB4 to indicating lung integrity in a newly established long-term porcine severe trauma model (polytrauma, PT) was explored...

Penile cancer accounts for 1-10% of men neoplastic diseases and 30-60% of patients have inguinal metastases at the time of diagnosis. Inguinal metastases of penile cancer with femoral vessel involvement could lead to vascular fistula and hemorrhagic shock. We present 3 consecutive patients with inguinal metastases of penile cancer complicated by infection and hemorrhage from femoral vessels invaded by the tumor. Simultaneous extra-anatomical axillo-femoral bypass graft, wide excision of tumor and groin defect reconstruction was used to achieve "tumor-free" oncologic aim and to save the lower limb...

Dengue infections are among the most frequent causes of febrile disease in tropical climates. Infections are caused by a flavivirus transmitted by the Aedes mosquito. Aedes aegypti mosquitos are the main transmitters of Dengue viruses. Since these insects are both diurnal and container breeders, particular prevention and control measures are required. Symptom severity varies and can range from a mild, flu-like clinical picture to severe hemorrhage and shock. The most common symptoms experienced by travelers include fever, muscular pain, headaches and skin rash...

Michel R Popoff
Clostridium difficile and Clostridium sordellii produce related potent toxins (C. difficile toxin A (TcdA) and toxin B (TcdB), C. sordellii lethal toxin (TcsL) and hemorrhagic toxin (TcsH)) which belong to the large clostridial glucosylating toxin (LCGT) family. TcsL is the main C. sordellii toxin as most of toxigenic C. sordellii strains only synthesize this toxin. Intestinal colonization by C. difficile subsequently to unbalanced microbiota is accompanied by release of toxins which induce local tissue destruction and severe inflammatory response...

BACKGROUND: Systemic inflammation and coagulopathy are major drivers of injury progression following hemorrhagic trauma. Our aim was to examine the effect of small-volume 3% NaCl adenosine, lidocaine and Mg2+ (ALM) bolus and 0.9% NaCl/ALM 'drip' on inflammation and coagulation in a rat model of hemorrhagic shock. METHODS: Sprague-Dawley rats (429±4 g) were randomly assigned to: 1) shams, 2) no-treatment, 3) saline-controls, 4) ALM-therapy, and 5) Hextend®. Hemorrhage was induced in anesthetized-ventilated animals by liver resection (60% left lateral lobe and 50% medial lobe)...

Glucose metabolism status may play a predictive role in the severity of the complications among patients with type 2 diabetes mellitus (DM). However, few studies have focused on the prognostic value of glycosylated hemoglobin (HbA1c) and Homeostatic Model Assessment 2 for Insulin Resistance (HOMA2-IR) in patients with DM, non-ST-segment elevation infarction (NSTEMI), and single concomitant chronic total occlusion (CTO) following primary percutaneous coronary intervention (PCI). Short- and long-term prognostic value of HbA1c and HOMA2-IR in patients with DM with NSTEMI and single CTO who received primary percutaneous transluminal coronary intervention (pPCI)...

Kyle J Kalkwarf, Bryan A Cotton
Hemorrhage is the leading cause of preventable deaths in trauma patients. After presenting a brief history of hemorrhagic shock resuscitation, this article discusses damage control resuscitation and its adjuncts. Massively bleeding patients in hypovolemic shock should be treated with damage control resuscitation principles including limited crystalloid, whole blood or balance blood component transfusion to permissive hypotension, preventing hypothermia, and stopping bleeding as quickly as possible.

In their post-traumatic course, trauma patients suffering from multiple injuries have a high risk for immune dysregulation, which may contribute to post-injury complications and late mortality. Monocytes as specific effector cells of the innate immunity play a crucial role in inflammation. Using their Pattern Recognition Receptors (PRRs), notably Toll-Like Receptors (TLR), the monocytes recognize pathogens and/or pathogen-associated molecular patterns (PAMPs) and organize their clearance. TLR2 is the major receptor for particles of gram-positive bacteria, and initiates their phagocytosis...

Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) are an increasingly established advanced therapy for emerging severe lung and/or cardiocirculatory dysfunction or failure. Several reports have provided evidence for a potential benefit in prognosis by ECLS in cases of cardiogenic shock including cardiopulmonary resuscitation. Routine use in specialized centers reduces the incidence of negative side effects (e.g., vascular/ischemic, embolic, hemorrhagic, hemolytic and, furthermore, septic)...
