[Metallic stents as a new therapeutic procedure for urinary tract obstruction].
ABSTRACT Tube stents are widely used to achieve internal urinary drainage in the urology field. Recently, in an attempt to improve upon metallic stents, these stents were introduced for use in the obstructed urethra and ureter. We review the current indications and devices for internal urinary drainage using metallic stents. In recent years, intraprostatic metallic stents have been established as a minimally invasive alternative treatment for benign prostatic hyperplasia (BPH). Appropriate patient selection and optimal stent positioning are required. However, intraprostatic metallic stents represent a useful option to BPH therapy for high operative-risk patients. Only limited data exist concerning patency rates and the efficacy of stent treatment of ureteral obstruction, and the indications for the implantation of metallic stents in these patients is controversial. The efficacy of metallic stents in this situation is not clear, but some investigators suggest that the implantation of metallic stents in obstructed ureters may be safely and effectively performed in patients with incurable malignancies.
Article: Collaborative control initiatives targeting zoonotic agents of alveolar echinococcosis in the northern hemisphere.[show abstract] [hide abstract]
ABSTRACT: Alveolar echinococcosis is one of the most important lethal zoonotic helminth infections in the northern hemisphere. Currently, the threat to public health is increasing, as evidenced by the rising prevalence rate of alveolar echinococcosis, as well as the invasion of urban areas by infected wild foxes. This threat is further increased due to the involvement of pet dogs, and probably cats, as emerging sources of infection. These increased threats to public health also have associated economic risks; therefore, there is a need for effective and sustainable methods of control. In this paper, initiatives to control alveolar echinococcosis by targeting its definitive hosts through anthelmintic baiting campaigns initiated by local residents who used local resources for bait production, distribution and collection of fecal samples for diagnosis are described. Further, when such distribution programs are coupled with the use of GIS-based maps, the optimum distribution of bait was obtained. These programs have also included the use of intravital diagnostic analyses of infection rates, which have been overseen by the Forum on Environment and Animals (FEA), and also allowed a nationwide monitoring of echinococcosis in difinitive hosts. In addition, a government initiative requiring mandatory reporting of echinococcosis in dogs to health authorities was recently initiated in Japan. Overall, the results of this study have shown that use of collaborative control initiatives targeting zoonotic agents of alveolar echinococcosis can be an effective method for reducing the threat of lethal echinococcosis in the northern hemisphere.Journal of Veterinary Science 01/2008; 8(4):313-21. · 1.16 Impact Factor
