To assess the efficacy of antimicrobial-impregnated catheters in preventing catheter-related infections during external ventricular drainage (EVD), we performed a meta-analysis and systematic review. We systematically searched Medline, Embase, and the Cochrane Library. All randomized controlled trials (RCTs) and nonrandomized prospective studies (NPSs) related to antimicrobial-impregnated EVD c...

background: one approach for prevention of cutaneous leishmaniasis is creation of a barrier between the insect vector (phlebotomus) and the host.  many, but not all, researchers claim that permethrin-impregnated uniforms are effective for prevention of cutaneous leishmaniasis.  we determined the efficacy of permethrin-impregnated uniforms for prevention of cutaneous leishmaniasis among iranian ...

neuroendocrine tumors (nets) constitute a heterogeneous group of neoplasms including carcinoids, pancreatic neuroendocrine tumors, pituitary tumors, medullary thyroid carcinoma and phaeochromocytomas. the symptoms and the outcome of nets differ considerably between patients depending on several factors. by labelling tracers with a radioisotope, the tracer acts as a carrier to deliver the radioa...

Current modeling techniques are not well equipped to design dynamic software architectures. In this work we present the basic concepts for a dynamic architecture modeling using nets-within-nets. Netswithin-nets represent a powerful formalism that allows active elements, i.e. nets, to be nested in arbitrary and dynamically changeable hierarchies. Applying the concepts from nets-within-nets, ther...

Effects of knockdown resistance (kdr) were investigated in three pyrethroid-resistant (RR) strains of the Afrotropical mosquito Anopheles gambiae Giles (Diptera: Culicidae): Kou from Burkina Faso, Tola and Yao from Côte d'Ivoire; compared with a standard susceptible (SS) strain from Kisumu, Kenya. The kdr factor was incompletely recessive, conferring 43-fold resistance ratio at LD50 level and 2...

Dear Editor, We compliment Tipayamongkholgul and Lisakulruk for their spatial regression analysis of different local socio-geographic predictors of dengue infection in the Thai province of Prachuap Khiri Kan, published in Geospatial Health, issue 5.2 (2011). However, for such a comprehensive analysis, we feel that it is essential that full details about the local vectors and the casual and form...

Since the advent of microsurgical techniques in the early part of the last century, it has been known that animal cells can survive the experimental creation of very large holes (>1000 μm2) in their surface (reviewed in Chambers and Chambers, 1961; Heilbrunn, 1956). Remarkably, these initial observations of a truly remarkable cell capacity failed, for many subsequent decades, to generate furthe...

CONTEXT A recent randomized controlled trial and meta-analysis indicated that central venous catheters impregnated with an antiseptic combination of chlorhexidine and silver sulfadiazine are efficacious in reducing the incidence of catheter-related bloodstream infection (CR-BSI); however, the ultimate clinical and economic consequences of their use have not been formally evaluated. OBJECTIVE ...
