“…Schistosomiasis was diagnosed by ultrasonographic (US) and/or computer tomographic (CT) modalities or serological examinations [4]. Two kinds of serological tests, which can detect past history of schistosomiasis, were available in this study.…”

“…In brief, IgG antibodies binding to two different schistosome antigens, Sj adult worm antigen and Sj egg antigen, were detected using an enzyme-linked immunosorbent assay (ELISA). As it is now accepted that ELISA titer of egg antigen-specific IgG is reliable for case-detection rather than IgG for adult worm antigen [4][5][6], the results based on the egg antigenspecific IgG were accepted in this study. Samples of more than 0.25 of optical density at 415 nm were determined to be positive, as previously confirmed [4][5][6].…”

“…44 However, their sustainability has been questioned, and the eradication of schistosomiasis will also depend on health education, behavioral changes, sanitation, and safe water supply. 45 In summary, based on the results of this metaanalysis, artesunate is clearly inferior to praziquantel for the treatment of urinary schistosomiasis. The question of whether combination therapy could be of interest or whether other artemisinin derivatives could be useful remains unanswered.…”

Objective: Efficacy of artemisinin derivatives alone or in combination compared to praziquantel alone for the treatment of urinary schistosomiasis in schoolchildren. Methods: Randomized clinical trials comparing praziquantel with artemisinin derivatives in the treatment of urinary schistosomiasis in schoolchildren were included. Medline, EMBASE, LILACS, CENTRAL, African Index Medicus, and Scielo were searched. We also analyzed the abstracts of the main conferences on infectious diseases and tropical medicine during the years 2009-2011. Google Scholar and OpenSIGLE were also searched. The last search was performed in July 2012. The primary endpoint was the cure rate. The main outcome data were retrieved using a standardized form; three independent researchers (WP, HC, and SS) performed the search, retrieved data, and evaluated the risk of bias. Disagreements were resolved by discussion. Risk ratios were used and heterogeneity was evaluated. A fixed or random-effects model was used according to the results of heterogeneity testing. An intention-to-treat analysis was done. Data were analyzed using Revman 5.0.24 (Copenhagen: The Nordic Cochrane Centre). Results: Seven studies were selected for full text review and only five studies were finally included. The cure rate for praziquantel was superior to that of artesunate (RR: 1.66; 95% CI: 1.18-2.33). Artesunate was not clearly superior to placebo (artesunate versus placebo, RR: 3.21; 95% CI: 0.50-20.74). Combination of artesunate with praziquantel could prove more beneficial than praziquantel alone (RR: 1.15; 95% CI: 1.01-1.31). The frequency of adverse events was equivalent for both drugs (praziquantel versus artesunate, RR: 1.11; 95% CI: 0.80-1.55). Conclusions: Our meta-analysis showed that praziquantel was significantly more effective than artesunate for the treatment of urinary schistosomiasis in schoolchildren. Artesunate at best had a marginal role in combination therapy.

209Introducción. Estudios previos demostraron la presencia de Paragonimus sp. en cangrejos de tres municipios en la cuenca del río Medellín. Para diseñar un plan para el control y la prevención de la paragonimosis, es necesario determinar la presencia del parásito en la parte alta del río, con la participación de la comunidad educativa, para dirigir su atención hacia el recurso hídrico. Objetivo. Establecer la presencia de metacercarias de Paragonimus sp. en cangrejos de las quebradas La Miel y La Clara, y sensibilizar a la comunidad educativa hacia el manejo adecuado de sus ecosistemas acuáticos. Materiales y métodos. En 2007 y 2008 se recolectaron cangrejos de quebradas de las veredas LaMiel y La Clara. En el laboratorio se relajaron y sacrificaron para buscar metacercarias de Paragonimus sp. y determinar la especie. Con estudiantes de instituciones educativas de ambas veredas, se llevaron a cabo cinco talleres lúdicos, para mejorar la percepción de su relación con sus quebradas. Resultados. Se capturaron nueve cangrejos Hypolobocera bouvieri. En La Miel se halló uno con Paragonimus sp. En La Clara se encontró, además, Aroapyrgus colombiensis, molusco huésped del parásito. Con los estudiantes se estableció que los ecosistemas acuáticos ejercen una gran atracción sobre ellos; sin embargo, desconocen los riesgos y no sostienen una relación responsable. Conclusiones. Se señala la presencia de focos de Paragonimus sp. en la parte alta del río Medellín; por lo tanto, el municipio de Caldas debe incluirse en los programas de prevención y control. La población estudiantil requiere nuevos programas educativos para mejorar la interacción con los ecosistemas acuáticos y disminuir el deterioro de su salud.Palabras claves: Paragonimus sp., ambiente acuático, educación, salud. Paragonimus sp. in crabs and awareness of the educational community to aquatic ecosystems in La Miel and La Clara, Caldas, AntioquiaIntroduction. Previous research has demonstrated the presence of Paragonimus spp. in crabs of three municipalities located in the Medellín river basin. To design a plan for the control and prevention of paragonimosis, parasite presence must be demonstrated in the upper area of the river, and an awareness campaign of its risks must involve the participation of the educational community in focusing attention on the local aquatic resources. Objective. The presence of Paragonimus spp. metarcercariae was established in freshwater crabs from La Miel and La Clara streams, and an awareness campaign created public awareness to management of the aquatic ecosystems for risk reduction. Materials and methods. Nine crabs were collected from streams of La Miel and La Clara villages in 2007 and 2008. The crabs were indentified, sacrificed in the laboratory and examined for presence of Paragonimus spp. metacercariae. Five workshops were conducted with students of educational institutions of the two villages to improve the student perception of paragonimosis risks associated with the local streams. Results. The crabs were identified as Hy...
