Pain management & opioid dose reduction with topical sevoflurane instillations in intractable venous ulcers: a case report

Abstract Vascular ulcers (VU) constitute a major cause of pain and disability, and significantly compromise quality of life. VU have a natural tendency to become chronic and in many cases exhibit anunsatisfactoryresponse to many of the standard therapeutic options.The case of a 73 year-old Caucasian female with severe pain and poorly-controlled pain (Visual Analogic Scale-VAS- of 8-9) due to three lower leg long-standing VUs is reported and discussed herein. The patient was treated with topical instillations of undiluted sevoflurane as per institutional off-label protocol (starting doses of 1mL/cm2 twice a day, and up-titrated according to response to a maximum of 7 mL twice daily). The VAS score dropped to 0-1 shortly after initiation of therapy and remained stable throughout treatment up until the closure of the observations. Subsequently, opioid therapy was gradually tapered down and ultimately abandoned.Sevoflurane application resulted on adequate and sustained pain management of refractory VU, with no significant side effects. On account of its beneficial effectivity and safety profiles, topical sevoflurane emerges as an add-on alternative for the long-term management of VU, and potentially other painful conditions.

Critical analysis of Chagas disease treatment in different countries

As a result of globalization and constant migratory flows, Chagas disease is now present in almost all continents. The management and treatment of the disease is often influenced by the economic and social context of the societies that host patients. In this manuscript, we aim to provide a comparative review of approaches to patients with Chagas disease in the Americas and Europe.

Evaluación externa de registros de cáncer de base poblacional: la Guía REDEPICAN para América Latina / External evaluation of population-based cancer registries: the REDEPICAN Guide for Latin America

OBJETIVO: Evaluar la factibilidad y la adecuación de la Guía REDEPICAN (Red Iberoamericana de Epidemiología y Sistemas de Información en Cáncer) a la situación actual de los Registros de Cáncer de Base Poblacional (RCBP) en América Latina y el Caribe como herramienta útil para mejorar dichos registros. MÉTODOS: La Guía fue diseñada por expertos en registros de cáncer y auditorías sanitarias, y se establecieron siete dominios para evaluarla. Para cada dominio se eligieron varios criterios con sus correspondientes estándares. Se determinaron tres niveles de cumplimiento del estándar. Se organizaron dos cursos de formación de evaluadores externos y tres paneles de discusión con expertos. La Guía se probó en seis RCBP de América Latina y España. RESULTADOS: La Guía contiene 68 criterios, 10 de ellos considerados esenciales para un RCBP. De acuerdo con la puntuación alcanzada, el registro se considera como aceptable (41-199), bueno (200-299) o excelente (300-350). El dominio sobre Métodos de registro representa el 25% de la puntuación, seguido por la Exhaustividad y validez (19%), la Difusión de resultados (19%), la Estructura (13%), la Confidencialidad y aspectos éticos (11%), la Comparabilidad (9%) y el Manual de procedimiento (3%). El proyecto piloto permitió: 1) perfeccionar criterios y estándares, 2) ampliar el concepto de calidad para incorporar las necesidades de los clientes y 3) potenciar la sección de Difusión de resultados. Dos registros latinoamericanos evaluados mejoraron su calidad hasta alcanzar el estándar de la Agencia Internacional de Investigación sobre el Cáncer. CONCLUSIONES: La guía REDEPICAN se ha elaborado teniendo en cuenta el contexto de los registros en América Latina y constituye una herramienta útil y novedosa para la mejora de la calidad de los RCBP. Además está preparada para ser utilizada en otros países y registros.

OBJECTIVE: Evaluate the feasibility of the REDEPICAN Guide (Red Iberoamericana de Epidemiología y Sistemas de Información en Cáncer) and its adaptation to the current situation of population-based cancer registries (PBCRs) in Latin America and the Caribbean as a useful tool to improve these registries. METHODS: Experts in cancer registries and health audits designed the guide and developed seven domains to evaluate in PBCRs. Several criteria were selected for each domain, with corresponding standards, scored according to three levels of compliance. Two training courses for external evaluators and three discussion panels for experts were organized. The guide was tested in six PBCRs in Latin America and Spain. RESULTS: The guide contains 68 criteria, 10 of which are considered essential for a PBCR. Based on its score, a registry is regarded as acceptable (41-199), good (200-299), or excellent (300-350). The registry methods domain accounts for 25% of the score, followed by completeness and validity (19%), dissemination of outcomes (19%), structure (13%), confidentiality and ethical aspects (11%), comparability (9%), and the procedures manual (3%). The pilot project enabled (1) enhancement of criteria and standards, (2) expansion of the quality concept to include client needs, and (3) strengthening the dissemination of outcomes section. Two of the Latin American registries that were evaluated improved their quality, meeting the standards of the International Agency for Research on Cancer. CONCLUSIONS: Development of the REDEPICAN Guide has taken into account the context of the registries in Latin America and is a useful and innovative tool for improving the quality of PBCRs. Furthermore, it is ready for use in other countries and registries.
