RESUMO
Resumen La leishmaniasis es una enfermedad desatendida, transmitida por dípteros de los géneros Phlebotomus y Lutzomyia. Existen tres formas clínicas principales de leishmaniasis: una visceral, y dos tegumentarias, las cuales se dividen en leishmaniasis cutánea (LC) y leishmaniasis mucocutánea (LM), todas presentes en Paraguay. El objetivo de este trabajo es describir las características epidemiológicas de la leishmaniasis tegumentaria en Paraguay. Aquí analizamos datos epidemiológicos de leishmaniasis tegumentaria (incluyendo LC y ML), tomados desde el 2006 hasta el 2017. La identidad de los pacientes se mantuvo confidencial. Un total de 2.918 casos positivos de leishmaniasis fueron estudiados. El pico de casos reportados se dio en el 2007. Una vista general muestra una disminución en la tendencia de leishmaniasis tegumentaria, donde los varones son más afectados que las mujeres, y el área endémica está localizada en las zonas este y noreste de Paraguay. Los casos en el Chaco (al oeste del Río Paraguay) están en aumento. La incidencia de leishmaniasis tegumentaria para el país es de 4 personas por 100.000 habitantes. Esta es considerada una enfermedad ocupacional ya que el 67% de los pacientes infectados fueron trabajadores rurales. Durante el periodo de estudio, la LC fue más común que la LM, excepto en los años 2010, 2014 y 2017. La mayoría de los pacientes afectados por LM son de avanzada edad. Conclusión. Remarcamos que la leishmaniasis no está restringida a las áreas húmedas del este de Paraguay, debido a que está también presente en zonas xerofíticas de Paraguay y Bolivia. Los trabajadores rurales de sexo masculino comprenden el grupo más susceptible. La alta frecuencia de LM en algunos años indica que es necesario que las agencias nacionales lleven a cabo más programas de educación en salud para prevenir o reducir la carga de LC (y por consiguiente también de LM) en el país.
Abstract Leishmaniasis is a neglected disease transmitted by sandflies of the genera Phlebotomus and Lutzomyia. There are three main clinical forms of leishmaniasis: one visceral and two tegumentary, differentiated between cutaneous leishmaniasis (CL) and mucocutaneous leishmaniasis (ML), all present in Paraguay. The objective of this work is to describe the epidemiologic characteristics of tegumentary leishmaniasis in Paraguay. Here we analyzed epidemiological data of tegumentary leishmaniasis (including CL and ML), taken from 2006 to 2017. Patients' identities were kept confidential. A total of 2,918 cases of positive leishmaniasis infection were studied. The peak of reported cases was in 2007. An overview shows a decrease in the trend of tegumentary leishmaniasis, where males are more affected than females, and the endemic area located on the east and north-eastern parts of Paraguay. Cases in the Chaco (west of Paraguay river) are increasing. The incidence of tegumentary leishmaniasis for the country is 4 persons per 100,000 inhabitants. This is considered an occupational disease since 67% of the infected patients were rural workers. During the period of study CL was more common than ML, except for the years 2010, 2014, and 2017. Most of the patients affected by ML are elders. Conclusion. We remark that leishmaniasis is not only restricted to the humid area of eastern Paraguay, since it is also present in xerophytic areas of Paraguay and Bolivia. Male rural workers are the most susceptible group. The high frequency of ML in some years indicates that more educational programs have to be carried out by national agencies to prevent and reduce the burden of CL (and thus also ML) in the country.
RESUMO
UNLABELLED: The use of coronary stents in coronary angioplasty has evolved dramatically in its design, type materials, polymers, and a variety of drugs, the use of coronary stents covered nitric oxide have shown satisfactory results in practice, however compared to the results reported drug-eluting stents, there is little information. OBJECTIVES: The aim of this study was to compare clinical outcomes of a stainless steel stent Bioactive nitric oxide coated titanium (BAS) and a drug-eluting stent zotarolimus (DES) in daily clinical practice. METHODS: A retrospective, analytical, descriptive and comparative study aimed at evaluating the safety and efficacy of two devices with different characteristics in our population. The primary endpoints were: death, acute infarction (AMI), and re intervention injury Treated (RLT). RESULTS: A total of 759 patients were included in the study which was performed angioplasty to a single vessel. Were divided into two arms 382 with DES and 377 patients with BAS, the one year follow up was carried in 95%. After this follow-up period, primary points (cardiovascular death, myocardial infarction, TLR and stent thrombosis) for arm DES vs BAS; 9.5% vs 8.5% P=NS but with shorter periods of dual antiplatelet therapy for arm BAS 6.9±4.1 vs 11.1±2.5 months DES P=.0001. The results were independent of the clinical syndrome of presentation. CONCLUSIONS: After one year of follow no statistically significant difference in major clinical events, there was a trend in favour of BAS vs SM with respect to revascularization of the target lesion without reaching statistical significance.
