Conclusiones: se demostró que el temefos, en su formulación Biolarv G1, puede tener mayor efectividad en recambios del 30 % de agua, con una durabilidad de alrededor de 30 días, lo que propicia la protección de los depósitos durante los ciclos de trabajo diseñados para la vigilancia y lucha antivectorial en Cuba.

ABSTRACT Introduction: temefos is the most widely used product for focal treatment. It exists in different formulations and is applied for drinking water tanks, in the form of sand-like granules at a concentration of 1 %. Objective: to determine the duration of temefos effectiveness, in its Costa Rican formulation Biolarv G1, in a Matanzas population of Culex quinquefasciatus. Materials and methods: a laboratory bioassay was performed, using the F1 of a Matanzas strain of Culex quinquefasciatus, which was subjected to the effects of Biolarv G1, lot 1180829. Three variants of drinking water replacement were used. Results: the effectiveness was 100% of larval mortality until the 7th day when 100 % of wáter was replaced. For the replacement of 50 % of water, average mortality was 97.5 % from the 1st to the 17th day. In the case of 30 % water replacement, mortality was 100 % up to the 27th day. Conclusions: it was shown that temefos, in its formulation Biolarv G1, can be more effective in replacements of 30 % of water, with a durability of about 30 days, which facilitates the protection of reservoirs during work cycles designed for surveillance and anti-vector control in Cuba.

Vigilancia entomológica de culícidos en la provincia de Matanzas durante el año 2015 / Entomological surveillance of culicids in the province of Matanzas during 2015

Introducción: la vigilancia entomológica es la recolección de información sobre los vectores de enfermedades y su entorno. Es un componente de la vigilancia epidemiológica, que consiste en una actividad del control de los vectores que se realiza durante todo el año, para conocer la presencia de estos en un área geográfica, la densidad de sus poblaciones, así como identificar los principales criaderos y los más productivos. Objetivo: identificación de las especies de culícidos que circularon en la provincia de Matanzas, durante el año 2015, así como la definición de la especie que predominó y tipificación de los depósitos más colonizados por estos en su fase de vida inmadura. Materiales y Métodos: se realizó un análisis de las estadísticas de la vigilancia entomológica durante el año 2015. Según la metodología descrita en el Programa Nacional de Vigilancia y Lucha Antivectorial se clasificó los depósitos, se colectaron y diagnosticaron las muestras. Resultados: las muestras larvarias aportaron la mayor cantidad de datos. Los depósitos de agua situados en el exterior de las viviendas, y dentro de estos las larvitrampas fueron los más utilizados por los mosquitos. La especie predominante en fase inmadura fue Aedes albopictus, mientras que en fase adulta Culex quinquefasciatus. Conclusiones: se identificaron 5 géneros con 25 especies de culícidos, el 36,8 % de la fauna cubana. Como especie predominante se define al A. albopictus. Los depósitos más explotados por estos organismos según su ubicación, fueron los del exterior, y según su tipo, fueron las larvitrampas (grupo E) (AU).

Introduction: the entomological surveillance is the recollection of information on diseases´ vectors and their environment. It is part of the epidemiologic surveillance, and it is an activity of vectors controlling carried out around the year to determine their presence in a geographical area, the density of their populations, and to identify their main breeding places and the most productive ones. Objectives: to identify the culicids species living in the province of Matanzas during 2015, and also to define the predominating specie and to typify the deposits more colonized by them in the in-mature life stage. Materials and Methods: it was carried out an analysis of the entomological surveillance statistics during 2015. The reservoirs were classified, and the samples were collected and diagnosed according to the methodology described in the National Program of Antivectorial Surveillance and Struggle.

Calidad del hibitane como desinfectante químico en la prevención y control de la contaminación microbiana / Quality of the hibitane as a chemical disinfectant in the prevention and control of the microbial contamination

El empleo de disoluciones químicas desinfectantes en la prevención de las infecciones intrahospitalarias representa una problemática compleja, por diversas causas, estas no cumplen los requisitos de calidad físico-químicos establecidos para su manejo efectivo, lo que origina contaminación microbiológica por gérmenes perjudiciales a la salud y al medio ambiente, el objetivo de este trabajo es hacer un estudio descriptivo sobre el control de la calidad del hibitane como principal solución desinfectante utilizada en el Hospital Clínico-Quirúrgico Universitario Comandante Faustino Pérez, en el período que abarca desde enero de 1997 hasta diciembre de 2006. En esta etapa se chequeó la calidad de esta disolución, según la normativa de la vigilancia higiénico-epidemiológica, y se pudo comprobar que la misma no cumple los parámetros establecidos para tales efectos, con vista a minimizar los impactos negativos que ejerce la contaminación microbiológica sobre la salud humana y el medio ambiente

The usage of chemical disinfectant dissolutions in the prevention of the in-hospital infections is a complex problem because of different causes; they do not fulfil the established physical-chemical requirements of quality for its effective handling, what originates microbiologic contamination for germs that are harmful to the health and the environment: The objective of this work was making a descriptive study on the quality control of the hibitane like a main disinfectant solution used in the University Clinic-surgical Hospital Comandante Faustino Pérez, in the period from January 1997 to December 2006. In this period we checked the quality of this dissolution, according to the normative of the hygiene-epidemiologic surveillance, and we stated that it does not fulfil the established parameters, with the objective of minimizing the negative impacts exerted by the microbiologic contamination on the human health and the environment

Frequency of the different mutations causing spinocerebellar ataxia (SCA1, SCA2, MJD/SCA3 and DRPLA) in a large group of Brazilian patients

Spinocerebellar ataxia type 1 (SCA1), spinocerebellar ataxia type 2 (SCA2) and Machado-Joseph disease or spinocerebellar ataxia type 3 (MJD/SCA3) are three distinctive forms of autosomal dominant spinocerebellar ataxia (SCA) caused by expansions of an unstable CAG repeat localized in the coding region of the causative genes. Another related disease, dentatorubropallidoluysian atrophy (DRPLA) is also caused by an unstable triplet repeat and can present as SCA in late onset patients. We investigated the frequency of the SCA1, SCA2, MJD/SCA3 and DRPLA mutations in 328 Brazilian patients with SCA, belonging to 90 unrelated families with various patterns of inheritance and originating in different geographic regions of Brazil. We found mutations in 35 families (39 percent), 32 of them with a clear autosomal dominant inheritance. The frequency of the SCA1 mutation was 3 percent of all patients; and 6 percent in the dominantly inherited SCAs. We identified the SCA2 mutation in 6 percent of all families and in 9 percent of the families with autosomal dominant inheritance. The MJD/SCA3 mutation was detected in 30 percent of all patients; and in the 44 percent of the dominantly inherited cases. We found no DRPLA mutation. In addition, we observed variability in the frequency of the different mutations according to geographic origin of the patients, which is probably related to the distinct colonization of different parts of Brazil. These results suggest that SCA may be occasionally caused by the SCA1 and SCA2 mutations in the Brazilian population, and that the MJD/SCA3 mutation is the most common cause of dominantly inherited SCA in Brazil.

Clinical and molecular characteristics of a brazilian family with spinocerebellar ataxia type 1

The spinocerebellar ataxias (SCAs) are a clinically and genetically heterogeneous group of late onset neurodegenerative disorders. To date, seven different genes causing autosomal dominant SCA have been mapped:SCA1,SCA2, Machado-Joseph disease(MJD)/SCA3,SCA4,SCA5,SCA7 and dentatorubropallidoluysian atrophy (DRPLA). Expansions of an unstable trinucleotide CAG repeat cause three of these disorders: SCA1, MJD/SCA3 and DRPLA. We studied one Brazilian family segregating an autosomal dominant type of SCA. A total of ten individuals were examined and tested for the presence of the SCA1, MJD and DRPLA mutations. Three individuals, one male and two females, were considered affected based on neurological examination; ages at onset were: 32, 36 and 41 years. The first complaint in all three patients was gait ataxia which progressed slowly over the years. Six individuals showed one allele containing an expanded CAG repeat in the SCA1 gene. The mean size of the expanded allele was 48.2 CAG units. Instability of the expanded CAG tract was seen in the two transmissions that were observed in this family. In both occasions there was a contraction of the CAG tract. Our study demonstrates that SCA1 occurs in the Brazilian population. In addition, our results stress the importance of molecular studies in the confirmation of diagnosis and for pre-symptomatic testing in SCAs.
