Memórias do Instituto Oswaldo Cruz , 2010, DOI: 10.1590/S0074-02762010000500013
Abstract: rhodnius ecuadoriensis is considered the second most important vector of chagas disease in ecuador. it is distributed across six of the 24 provinces and occupies intradomiciliary, peridomiciliary and sylvatic habitats. this study was conducted in six communities within the coastal province of guayas. triatomine searches were conducted in domestic and peridomestic habitats and bird nests using manual searches, live-bait traps and sensor boxes. synantrhopic mammals were captured in the domestic and peridomestic habitats. household searches (n = 429) and randomly placed sensor boxes (n = 360) produced no live triatomine adults or nymphs. in contrast, eight nymphs were found in two out of six searched campylorhynchus fasciatus (troglodytidae) nests. finally, trypanosoma cruzi dna was amplified from the blood of 10% of the 115 examined mammals. environmental changes in land use (intensive rice farming), mosquito control interventions and lack of intradomestic adaptation are suggested among the possible reasons for the lack of domestic triatomine colonies.

Abstract: Background Failure to detect a disease agent or vector where it actually occurs constitutes a serious drawback in epidemiology. In the pervasive situation where no sampling technique is perfect, the explicit analytical treatment of detection failure becomes a key step in the estimation of epidemiological parameters. We illustrate this approach with a study of Attalea palm tree infestation by Rhodnius spp. (Triatominae), the most important vectors of Chagas disease (CD) in northern South America. Methodology/Principal Findings The probability of detecting triatomines in infested palms is estimated by repeatedly sampling each palm. This knowledge is used to derive an unbiased estimate of the biologically relevant probability of palm infestation. We combine maximum-likelihood analysis and information-theoretic model selection to test the relationships between environmental covariates and infestation of 298 Amazonian palm trees over three spatial scales: region within Amazonia, landscape, and individual palm. Palm infestation estimates are high (40–60%) across regions, and well above the observed infestation rate (24%). Detection probability is higher (~0.55 on average) in the richest-soil region than elsewhere (~0.08). Infestation estimates are similar in forest and rural areas, but lower in urban landscapes. Finally, individual palm covariates (accumulated organic matter and stem height) explain most of infestation rate variation. Conclusions/Significance Individual palm attributes appear as key drivers of infestation, suggesting that CD surveillance must incorporate local-scale knowledge and that peridomestic palm tree management might help lower transmission risk. Vector populations are probably denser in rich-soil sub-regions, where CD prevalence tends to be higher; this suggests a target for research on broad-scale risk mapping. Landscape-scale effects indicate that palm triatomine populations can endure deforestation in rural areas, but become rarer in heavily disturbed urban settings. Our methodological approach has wide application in infectious disease research; by improving eco-epidemiological parameter estimation, it can also significantly strengthen vector surveillance-control strategies.
Indications and therapeutical options in hepatolithiasis Indicaciones y opciones terapéuticas en la hepatolitiasis
J. M. Ramia,A. Palomeque,K. Muffak,J. Villar
Revista Espa?ola de Enfermedades Digestivas , 2006,
Abstract: Objective: to present our experience with the treatment of hepatolithiasis. Patients and methods: experimental design: a retrospective study. Every patient operated on during 2002-2004. Results: mean age was 68.2 years. All patients were male. Two patients had been operated on before. The other three suffered from: monolobar Caroli's disease (1), cholangiocarcinoma (1), and hepatolihtiasis without clear etiologic factors (1). All of them had intrahepatic and extrahepatic litihiasis. Clinical signs included: pain in RUQ, fever, and jaundice. Bilirubin was 3.5 mg/dl (min: 1.7, max: 5.9), GGT: 676.2 IU/l (min: 29, max: 2039), and alkaline phosphatase: 400 IU/l (min: 100, max: 1136). Abdominal ultrasounds always correctly diagnosed HL. CT (3 patients) only diagnosed one case. ERCP (3 patients) and cholangio-MRI (2 patients) always diagnosed HL correctly. Surgical procedures were: hepatojejunostomy with lavage of bile duct (2 cases) and hepatectomy (3 cases) -both right (1) and left (2). We always performed an intraoperative ultrasonography and choledoscopy. Morbidity was: biliary fistula (1 case) treated by percutaneous drainage. No mortality occurred. Median stay was 8.8 days. Mean follow-up is 12 months (min: 11, max: 20). No relapse has been observed. Conclusions: HL is infrequent in Spain. Surgical treatment, usually liver resection, obtains good results with low morbidity and mortality.

La 'historia' de los se?ores étnicos de Casabindo y Cochinoca (1540-1662)
Andes , 2006,
Abstract: the recovery and historical analysis of the stories of the native elders of the town of casabindo in 1662 about the history of their people and their authorities since the end of the "time of the inca" are the main concerns of this article. there, the history of this native group is included into the political and military history of the long and obscure period of the spanish invasion against the native population of this town in particular, but also of the towns located in neighboring areas, in the territories that today conform northern argentina and chile and southern bolivia. in order to understand the stories coming from the native population and include them into the study, we must recover, modify and reinterpret the usual stories of the jujuy provincial history in the period of the spaniards' final conquest of the region. these tended to recover the vision of the last conquerors, who could be named as the inhabitants of the government of the tucumán, avoiding the participation of other groups and colonial authorities such as those of the charcas inhabitants. a detailed consideration of the actions taken by different armies and colonial authorities and the connection between the documents available and the different interests in conflict permit to carry out a new type of analysis of the documents related to native societies. up to now, those documents only provided information that was understood as contradictory or that reflected a high lack of organization in these societies.
Nacimiento de Anarda: el retrato femenino a través del gongorismo en la lírica de Botelho de Oliveira

Perífrasis : Revista de Literatura, Teoría y Crítica , 2011,
Abstract: Durante el llamado Barroco literario, la temática del retrato femenino alcanza su mayor apogeo en la lírica europea. Siguiendo los patrones literarios inaugurados por lírica petrarquesca en la fase crepuscular de la edad, Luis de Góngora contribuye a la creación de una nueva discursividad respecto a este tema. En este contexto, en consonancia con los procedimientos de la translatio studii y según las normas de la imitatio que regían los procesos líricos en el momento, el brasile o Botelho de Oliveira se apropia del estilo gongorino para crear a su amada poética, Anarda, dotando a su obra de total originalidad.During the so-called literary Barroque, the subject matter referring to feminine portrait reaches its height in European lyric. Following the literary patterns inaugurated by Petrarca’s work during Middle Age’s twilight, Luis de Góngora contributes to the creation of a new discourse concerning this theme. In this context, the Brazilian Botelho de Oliveira appropriates Gongoric style in keeping with the translatio studii procedures and according to the imitatio rules that governed lyric processes at that time. By doing this, he creates his own poetic beloved Anarda, endowing his work with full originality.

"La `historia′ de los se ores étnicos de Casabindo y Cochinoca (1540-1662)"

Andes , 2006,
Abstract: La recuperación y el análisis histórico del relato de los ancianos indígenas del pueblo de Casabindo en 1662 sobre la historia de su pueblo y de sus autoridades desde el fin del "tiempo del inca", conforman las preocupaciones centrales de este artículo. Durante su desarrollo se avanza en la inclusión de la historia de este grupo indígena dentro de la historia política y militar del largo y confuso período de la invasión espa ola sobre las poblaciones indígenas de este pueblo en particular y también de los localizados en zonas vecinas, que habitaban los territorios que actualmente forman parte del norte de Argentina, de Chile y del sur de Bolivia. Esta búsqueda de comprensión y de inclusión de los relatos provenientes de los indígenas obliga a recuperar, modificar y reinterpretar los relatos históricos habituales sobre la historia provincial de Jujuy en el período de la conquista definitiva de los espa oles sobre esta zona, donde se tendía a recuperar la visión proveniente de sus últimos conquistadores, que podríamos denominarlos como los vecinos de la Gobernación del Tucumán, soslayando la participación de otras huestes y autoridades coloniales como las de los vecinos de Charcas. Un reconocimiento minucioso del accionar de diversas huestes y autoridades coloniales y el ir relacionando la documentación generada con los diversos intereses en pugna, permite comenzar un nuevo tipo de análisis sobre los documentos relativos al accionar de las sociedades indígenas que, hasta el momento, sólo brindaban informaciones que se entendían como contradictorias o que reflejaban un alto grado de desestructuración de las sociedades indígenas.
