Staphylococcus aureus is a leading cause of skin and soft tissue infections, foreign body infections, and infective endocarditis. In case of endovascular infection with S. aureus, higher rates of cardiac valve destruction, embolic complications, severe sepsis, and death occur. The unique capacity of S. aureus to induce clotting has been known for over a century; however, its role in virulence has long been controversial. S. aureus secretes two coagulases, staphylocoagulase and von Willebrand factor binding protein that both activate prothrombin to generate fibrin...

BACKGROUND: Staphylococcus epidermidis (S. epidermidis) has emerged as one of the leading pathogens of biomaterial-related infections. Vascular adhesion protein-1 (VAP-1) is an inflammation-inducible endothelial molecule controlling extravasation of leukocytes. Sialic acid-binding immunoglobulin-like lectin 9 (Siglec-9) is a leukocyte ligand of VAP-1. We hypothesized that (68)Ga-labeled 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid-conjugated Siglec-9 motif containing peptide ((68)Ga-DOTA-Siglec-9) could detect inflammatory response due to S...

Heparin may cause hyperkalemia by blocking aldosterone biosynthesis in the adrenal gland. Dizygotic twin sisters were born by Cesarean section at 25 weeks' gestation. The younger sister developed acute hyperkalemia (7.4 mEq/L) at 10 days of age. At the time of the development of the hyperkalemia, there were no signs of systemic infection, cardiac or renal failure, adrenal insufficiency, or sudden anemia. She was receiving no medication other than heparin to maintain the vascular catheter. Heparin was changed to dalteparin at 12 days of age...

Clostridium sordellii is a toxin producing ubiquitous gram-positive anaerobe, mainly associated with trauma, soft tissue skin infections, and gynecologic infection. We report a unique case of a new strain of Clostridium sordellii (not present in the Center for Disease Control (CDC) database) infection induced toxic shock syndrome in a previously healthy two-year-old male with colitis-related hemolytic uremic syndrome (HUS). The patient presented with dehydration, vomiting, and bloody diarrhea. He was transferred to the pediatric critical care unit (PICU) for initiation of peritoneal dialysis (PD)...

OBJECTIVE: The ethanol lock technique has shown great potential to eradicate organisms in biofilms and to treat or prevent central venous catheter related infections. Following instillation of ethanol lock solution, however, the inherent density gradient between blood and ethanol causes gravity induced seepage of ethanol out of the catheter and blood influx into the catheter. Plasma proteins so are exposed to highly concentrated ethanol, which is a classic agent for protein precipitation...

Arterial cannulation in neonates is usually performed for frequent blood pressure monitoring and blood sampling. The procedure, while easily executed by skilled neonatal staff, can be associated with serious complications such as vasospasm, thrombosis, embolism, hematoma, infection, peripheral nerve damage, ischemia, and tissue necrosis. Several treatment options are available to reverse vascular induced ischemia and tissue damage. Applied interventions depend on the extent of tissue involvement and whether the condition is progressive and deemed life threatening...

BACKGROUND: Cannulation of the radial artery is frequently performed for invasive hemodynamic monitoring. Complications arising from indwelling catheters have been described in small case series; however, their surgical management is not well described. Understanding the presentation and management of such complications is imperative to offer optimal treatment, particularly because the radial artery is increasingly accessed for percutaneous coronary interventions. METHODS: We conducted a retrospective review to identify patients who underwent surgical intervention for complications arising from indwelling radial artery catheters from 1997 to 2011...

Patients with cancer are at high risk for developing venous thromboembolism (VTE), and the presence of a central venous catheter (CVC) further increases this risk. CVC-related VTE has serious implications related to the loss of vascular access, development of pulmonary embolism, recurrent VTE, infections and post-thrombotic syndrome. The pathogenesis of CVC-related VTE is complex and multifactorial, with risk factors associated with the catheter, the vessel selected for insertion and the underlying cancer as well as the anti-cancer therapy...

Adherence of proteins, cells, and microorganisms to the surface of venous catheters contributes to catheter occlusion, venous thrombosis, thrombotic embolism, and infections. These complications lengthen hospital stays and increase patient morbidity and mortality. Current technologies for inhibiting these complications are limited in duration of efficacy and may induce adverse side effects. To prevent complications over the life span of a device without using active drugs, we modified a catheter with the nonleaching polymeric sulfobetaine (polySB), which coordinates water molecules to the catheter surface...

The permanent central venous catheter (CVCp) for vascular access is increasingly common in patients on hemodialysis. The main problem related to CVCp is the biofilm, which leads to malfunction and an increased risk of infections. In recent years lock solutions for the CVCp have become popular. Heparin should be abandoned because it induces rapid biofilm development and exposes the patient to the risk of bleeding due to overspill of heparin into the bloodstream. Citrate solution (3.8%) is associated with the best risk/benefit ratio for CVC functioning but offers no advantages in terms of reducing infections...

In general, therapeutic apheresis is a relatively safe procedure with the most commonly seen complications caused by citrate-induced hypocalcemia and urticarial reactions to the protein-containing replacement fluid. Depletion coagulopathy and immunoglobulin depletion must be anticipated when albumin is used as the replacement fluid and becomes more profound as the number of treatment increases. The most serious complications are seen when there is an anaphylactoid reaction to the multiple units of fresh frozen plasma required when used as the replacement fluid...

Background. The contribution of the hemodialysis (HD) vascular access type to inflammation is unclear. Methods. We conducted a prospective observational study in an incident HD population. C-reactive protein (CRP), interleukin-6 (IL-6), and interferon-γ-induced protein (IP-10) were measured before and at 6-time points after access placement for 1 year. Results. Sixty-four incident HD patients were included (tunneled catheter (TC), n = 40, arteriovenous fistula (AVF), n = 14, and arteriovenous graft (AVG), n = 10)...

Brian M Ilfeld
A continuous peripheral nerve block, also termed "perineural local anesthetic infusion," involves the percutaneous insertion of a catheter adjacent to a peripheral nerve, followed by local anesthetic administration via the catheter, providing anesthesia/analgesia for multiple days or even months. Continuous peripheral nerve blocks may be provided in the hospital setting, but the use of lightweight, portable pumps permits ambulatory infusion as well. This technique's most common application is providing analgesia after surgical procedures...

TAKEDA-143242 (TAK-242) is a small molecule shown to inhibit lipopolysaccharide-induced intracellular signaling and inflammation. In vitro studies demonstrated that TAK-242 can prevent release of TNF-α, IL-1β, and IL-6 from activated macrophages of several species, including pigs. This study tested the hypothesis that TAK-242 would protect pigs from lethal gram-negative peritonitis via an anti-cytokine mechanism. A validated model of porcine gram-negative peritonitis, which employs chronically inplantated cardiac transducers and aortic and pulmonary artery catheters, was used...

Chlorhexidine, a bisbiguanide, is widely used as an antiseptic agent in medical practice as it has the greatest residual antimicrobial activity. Central venous catheters coated extraluminally with chlorhexidine have been made to reduce extraluminal contamination. By using both the chlorhexidine-alchohol skin preparation and antimicrobial-coated catheters during vascular cannulation, it can reduce catheter related bloodstream significantly [1]. The reduction in infection rate is especially vital in critically ill patients who require long-term vascular access...
