Abstract: vancomycin-resistant enterococci (vre) have an important impact on pediatric oncology population. the objectives of this study were: to know the prevalence of vre intestinal colonization in oncology patients, to identify the risk factors that predispose hospitalized patients to vre intestinal colonization , and to determine the vre resistance profile to different antimicrobial agents. we studied all children with oncological disease aged 1 month to 16 years that had joined the protocol and had been hospitalized from october 2006 to april 2007. vre intestinal colonization was analyzed when the patient was admitted to hospital, 72 hours later, and weekly during hospitalization. a total of 333 samples were taken from 67 patients. from these, vre were isolated in 12 patients, with a prevalence of 17.9%. of the 28 isolates studied, taking one per patient, 10 were enterococcus faecium and 2 enterococcus faecalis, both with resistance phenotype vana (cim90 512 μg/ml to vancomycin and cim90 256 μg/ml to teicoplanin). the use of vancomycin (p=0.02), duration of neutropenia greater than 7 days (p=0.03) and prolonged hospitalization (42.8 days on average) (p=0.0001) were risk factors significantly related to vre colonization. we considered it necessary to carry out an epidemiological surveillance and to implement prevention and control measures.

Abstract: Objetivo: realizar la caracterización clínico epidemiológica del parasitismo intestinal en ni os de 0 a 5 a os pertenecientes al consultorio médico Altos de Uslar, Libertador, Carabobo, Venezuela. Métodos: se realizó un estudio descriptivo, de corte transversal durante los meses de enero a diciembre de 2006, en el que se estudiaron 83 ni os que presentaban sintomatología de parasitismo intestinal o no, a los que se les tomó muestras de heces fecales. La información se obtuvo a través de encuestas que se aplicaron a los tutores legales. Resultados: la frecuencia general de parasitismo fue de 67,48 %, con predominio del sexo masculino sobre el femenino; las especies más frecuentes fueron Ascaris lumbricoides y Enterobius vermicularis, y se identificó con poliparasitismo un 61,45 % de pacientes. Entre los factores que favorecieron las parasitosis se detectaron la presencia de vectores, los malos hábitos higiénicos sanitarios y la ingestión de agua no tratada. Conclusiones: predominó la edad de 5 a os y el sexo masculino, así como, el poliparasitismo, las infecciones por helmintos, y las malas condiciones higiénico-sanitarias de las viviendas; y como principales factores de riesgo estuvo la presencia de vectores, la insuficiente higiene de las manos y los alimentos de consumo, así como la baja calidad sanitaria del agua.

Abstract: introduction: malaria, intestinal parasitoses and malnutrition coexist and interact in people of malarious areas; it is required to know the magnitude of these diseases. objective: to identify the prevalence of intestinal parasites in children (aged 4-10 years) of malarious areas of antioquia (northwestern colombia), and to know the changes of parasites at days 8 and 30 after specific treatment. methodology: intestinal parasites surveys were applied before treatment (albendazole + secnidazole) and at days 8 and 30 after treatment. examination of stools (direct and concentration) were used in single samples. results: at day 1, 80% of the children showed some pathogenic helminth, 39% had some pathogenic protozoan, and 35% had both helminths and protozoa. specific prevalences at day 1 were as follows: ascaris lumbricoides 43.5%, trichuris trichiura 68.2%, necator americanus 37.6%, entamoeba histolytica, 15.3%, giardia lamblia 21.2%. the intensity of infection was slight (1-2 crosses) for protozoan parasites and it was moderateintense for helminth parasites, namely: 84% for a. lumbricoides, 83% for t. trichiura and 50% for n. americanus. the 'net effect on protozoan prevalence' attributable to treatment, measured at day 8, was e. histolytica 50% and g. lamblia 71% (p < 0.05). the 'net effect on helminth burden' (nehb) attributable to treatment (between days 1 and 8) was significant for a. lumbricoides and n. americanus. the nehb of albendazole, measured at day 8, was 91% for a. lumbricoides, 27% for t. trichiura and 87% for n. americanus. egg reduction was always significant (p < 0.05). conclusion: prevalence rates of intestinal parasites in turbo and el bagre, in children with malaria, aged 4-10 years, are still high and constitute a severe public health problem.

Abstract: abstract: iron deficiency is worldwide spread and ferropenic anemia is its most severe manifestation. age, poverty and parasitic infestations are some associated factors. this study was aimed to evaluate iron nutritional status and to establish relationship with age, gender and intestinal parasitic infestations in 264 children (aged 3 to14 years) attending to a school at valencia, carabobo. iron status was assessed by serum ferritin concentrations (elisa method) and hemoglobin (authomated method). parasitic infestation was determined by direct observation and kato katz method. prevalence of iron deficiency, anemia and iron deficiency anemia were 69.2%, 16.2% and 11.0%, respectively. iron deficiency and anemia were significantly higher in preschool children than in school children (79.3% and 23% vs 63.9% and 12.7%, p:<0.05). parasitic infestation was present in 58.4% of the children; being blastocystis hominis, entamoeba coli and giardia lamblia, the most frequent forms. no significant association was found between iron status and gender or parasitic infestation. results show a mild public health problem regarding anemia, a high prevalence of iron deficiency and intestinal parasitic infestation that could be the expression of sanitary and socioeconomic conditions. nutritional intervention based on education as fundamental tool to decrease anemia and iron deficiency prevalence should be initiated.an venez nutr 2007;20 (1): 5-11

Abstract: included in infectious diseases, yet at present times, intestinal parasitism is a problem for underdeveloped countries, and for those highly developed. to characterize intestinal parasitism in children aged 1 and 12, we carried out a cross-sectional descriptive study during may to july, 2007 in 2 communities, one suburban of "américa latina" parcel and other urban of "virginia" parcel, both served by "xx aniversario" polyclinic of santa clara municipality. we visited homes and we applied survey to parents to obtain data in this respect. a total of 243 children ware studied in both communities, taking samples of feces and of anal region by graham method. general frequency of parasitism was of 6,8 % greater in the children of "américa latina" parcel, and more frequent species were giardia lamblia and enterobius vermicularis. an unsuitable water disinfection, presence of vectors, to bite nails, a poor hygiene after animal contacts, presence of these in home, not washed vegetables, barefoot, and overcrowding, were the factors that more favouring parasitosis.

Abstract: Objetivos: Determinar el efecto de la administración de albendazol sobre los niveles de hemoglobina de ni os entre 8 y12 a os con enterobiasis intestinal. Métodos: Realizamos un estudio de cuasiexperimental. La población estudiada provino de la jurisdicción El Milagro-Ventanas, distrito de Sanagorán, provincia de Sánchez Carrión, departamento de La Libertad, Perú; entre los meses de noviembre de 2009 a abril de 2010. Se incluyeron a todos los ni os con diagnóstico definitivo de enterobiasis intestinal por test de Graham. Se realizó la toma de hemoglobina basal y posteriormente se administró albendazol 400mg en dos dosis separadas por 15 días. Seis meses después se realizó un nuevo dosaje de hemoglobina. Resultados: Se incluyeron un total de 30 ni os. En la primera medición de hemoglobina el 26.7% tenía una hemoglobina mayor de 11g/dL y el promedio fue de 10.1±1.1. Posterior al tratamiento, el 53% tuvo hemoglobina mayor de 11g/dL, con un promedio de 11±1.0 g/dL, existiendo aumento significativo de los valores de hemoglobina (p<0.001). No se observó efectos adversos al medicamento. Conclusión: La administración oral de albendazol, aumentó aproximadamente 1g/dL el nivel de hemoglobina en la población estudiada a los seis meses post tratamiento, por lo que podría ser beneficiosa la desparasitación masiva, de rutina, con el fin de disminuir la prevalencia de anemia en poblaciones con extrema pobreza de nuestro país.
