Timing and type of chemoprophylaxis (CP) that should be used in patients with traumatic brain injury (TBI) remains unclear. We reviewed our institutions experience with low-molecular-weight heparin (LMWH) and unfractionated heparin (UFH) in TBI. ⋯ LMWH is an effective method of CP in patients with TBI, providing a lower rate of venous thromboembolic and hemorrhagic complications when compared with UFH. A large, prospective, randomized study would better evaluate the safety and efficacy of LMWH in patients suffering blunt traumatic brain injury.

Infection is a major complication associated with combat-related injuries. One strategy to decrease infections is immediate delivery of antimicrobials at or near the point-of-injury by the casualty or the first medical responder. The 75th Ranger Regiment systematically collects data on prehospital battlefield care, including antimicrobial administration. We review infectious complications and colonization rates associated with delivery of point-of-injury antimicrobial therapy. ⋯ Although limited by population size, a significant difference in infection rates and multidrug-resistant pathogen colonization was not seen in those casualties who received single-dose broad-spectrum antimicrobials at the point-of-injury, confirming neither benefit nor harm. Overall adherence with initiating point-of-injury antimicrobials was low.

During the initial development of an Emergency General Surgery (EGS) service, severity of illness (SOI) can be expected to be high and should decrease as the service matures. We hypothesize that a matured regional EGS service would show decreasing mortality and length of stay (LOS) over time. ⋯ Despite consistently high SOI, a dedicated and matured EGS service demonstrated a decrease in mortality and LOS.

Nanofibers consisting of poly-N-acetyl glucosamine (pGlcNAc), as the functional component of products for surface hemostasis, have been shown to activate platelets and thereby the clotting mechanism. The nanofiber-activated platelets provide a catalytic surface for acceleration of the intrinsic coagulation cascade, thrombin generation, and fibrin polymerization. ⋯ These results provide evidence that pGlcNAc nanofibers activate platelets and accelerate the clotting of blood, and on how best to achieve surface hemostasis when patients are coagulopathic because of shock and/or to treatment with antiplatelet drugs.

Neer IIB distal clavicle fracture is associated with disruption of the coracoclavicular ligament and a variable degree of displacement. Surgical treatment using various implants such as intramedullary wires, screws, and plates has been described in the literature with satisfactory results. ⋯ Minimally invasive surgery using titanium cable seems to be a good option for the treatment of Neer IIB distal clavicle fractures, with early functional recovery and no requirement for revision surgery.
