“…Because this change cannot be explained by changes in the population according to census data from 1991, 2001, and 2007, it is also likely that sandfly vectors are adapting to different habitats. In the past, ATL was observed as the result of contact between people and forest environments 27 and later, in agricultural areas that had been previously deforested. 6,28 However, more recently, the disease has been increasingly found in urban areas.…”

Abstract. The Health Post of Corte de Pedra is located in a region endemic for American tegumentary leishmaniasis (ATL) in the Brazilian state of Bahia, and it treats 500-1,300 patients annually. To describe temporal changes in the epidemiology of ATL, we reviewed a random sample of 10% of patient charts (N = 1,209) from 1988 to 2008. There was a twofold increase in the number of cases over the 20-year period, with fluctuations in 10-year cycles. Patients were most frequently male, between the ages of 10 and 30 years, and engaged in agricultural labor; 4.3% of patients had mucosal disease, and 2.4% of patients had disseminated disease. Over the study period, the number of disseminated cases increased threefold, the proportion of cases in younger patients and agricultural workers decreased, and the proportion of patients residing in coastal areas increased. ATL is on the rise in Bahia, with a 10-year periodicity and evolving changes in epidemiology and manifestations of disease.

Abstract. Treatment alternatives have seldom been evaluated in children with cutaneous leishmaniasis (CL). We examine the clinical/epidemiological profile of children with CL considering international guidelines for local treatment. Descriptive analyses were conducted using International Center for Medical Research and Training (CIDEIM) case reports of parasitologically diagnosed patients 14 years of age from 2004 to 2010. Eligibility for local treatment based on World Health Organization/Pan American Health Organization (WHO/PAHO) criteria was determined. Among 380 children, 90% presented lesions of 3 months duration, 54% presented single lesions 30 mm in diameter, and 45% were 5 years old. Lesions on the head and neck were more frequent among children 0-5 years, and lesions below the head/neck were more frequent among 11-to 14-year-old children (P = 0.004). Using PAHO and WHO criteria, 26% and 53% of children, respectively, were eligible for local treatment. Recommended local treatments for New World CL have potential but limited applicability in children. Individual risk-benefit assessment and effectiveness data in children may increase eligibility.

“…L. columbiana se extiende desde bosques húmedos del Nudo de Los Pastos, pasando por las Cordilleras Occidental y Central, hasta zonas esteparias de La Guajira, en un rango altitudinal de 100 a 2.700 msnm (6,13). Este flebotomíneo ha sido infectado en el laboratorio con L. braziliensis (17) y Leishmania mexicana (73), y se ha postulado como transmisor en el suroccidente del país (17,66,(73)(74)(75).…”

La incriminación de especies de Lutzomyia del grupo verrucarum Theodor, 1965, en la transmisión de leishmaniosis en Colombia ha puesto de manifiesto la necesidad de conocer en detalle su distribución geográfica. Este trabajo pretende contribuir a su conocimiento mediante la incorporación de 34 registros nuevos, entre los que sobresalen el hallazgo de Lutzomyia spinicrassa en un bosque seco tropical de la Costa Atlántica, la presencia de Lutzomyia ovallesi en la Orinoquia y Amazonia y la simpatría de L. spinicrassa y Lutzomyia quasitownsendi en la Cordillera Oriental. Complementariamente, este artículo recopila y sintetiza la distribución municipal y altitudinal de las 19 especies registradas en el país. Los datos compilados muestran que la serie townsendi (L. spinicrassa, Lutzomyia longiflocosa, L. quasitownsendi, Lutzomyia sauroida, Lutzomyia torvida, Lutzomyia townsendi, Lutzomyia youngi) está generalmente asociada con los pisos altitudinales premontano y montano bajo, mientras la serie verrucarum hace presencia desde el piso tropical hasta el montano con taxones de extenso ámbito geográfico (Lutzomyia evansi, Lutzomyia columbiana, L. ovallesi, Lutzomyia nuneztovari, Lutzomyia nevesi) y taxones de distribución endémica (Lutzomyia andina, Lutzomyia disiuncta, Lutzomyia moralesi, Lutzomyia antioquiensis). De otro lado, los representantes de la serie pia (Lutzomyia pia, Lutzomyia limafalcaoae) y de la serie serrana (Lutzomyia serrana) aparecen desde el piso tropical hasta el montano bajo. Se postula que las divergencias en los rangos altitudinales podrían estar relacionadas intrínsecamente con el origen de las especies, derivándose de fenómenos climáticos y geológicos que han afectado la flora y fauna de la región andina.Palabras clave: Psychodidae, flebotomíneos, Lutzomyia, distribución, leishmaniosis, Colombia. New distributional records of the verrucarum species group (Diptera: Psychodidae) in ColombiaThe incrimination of sand flies belonging to verrucarum species group in the leishmaniasis transmission underscores the need for a detailed information on the geographical distribution of these species. The current listing adds 34 new records that extend significantly the knowledge of the geographical distribution of the verrucarum group in Colombia. The most important new records pertain to Lutzomyia spinicrassa in the tropical dry forest of the Atlantic coast, Lutzomyia ovallesi in the Orinoco and Amazon River watersheds regions of Colombia, and the sympatric occurrence of Lutzomyia spinicrassa and Lutzomyia quasitownsendi in the eastern chain of the Andes mountains. Additionally, the municipal and altitudinal distributions are compiled for 19 new species recorded for Colombia. The series townsendi of the verrucarum group generally restricted to premontane and lower montane zones based on distribution data on Lutzomyia longiflocosa, L. quasitownsendi, Lutzomyia sauroida, L. spinicrassa, Lutzomyia torvida, Lutzomyia townsendi and Lutzomyia youngi. The series verrucarum is distributed from the tropical lowland to...
