RESUMEN
Objetivo: Estudiar el uso de los medicamentos con indicaciones off-label en pediatría intrahospitalarios en una clínica de tercer nivel de la ciudad de Barranquilla-Atlántico. Metodología: El diseño empleado en este estudio fue observacional, donde se obtuvo la frecuencia de las prescripciones y administración de los medicamentos con indicación no aprobada. El estudio se realizó en cuatro fases, la primera fue la búsqueda sistemática de medicamentos basados en la literatura científica, en la segunda fase se seleccionaron los pacientes basados en los criterios de inclusión del estudio, la tercera fase se realizó el análisis y procesamiento de los datos y la cuarta fase fue la construcción del listado de medicamentos off-label Resultados: Se realizó un seguimiento a 204 pacientes de los pabellones Caribe y UCI Pediátrica, que cumplieran con los criterios de inclusión, durante el periodo de tres meses de estudio. Se identificaron 386 medicamentos con indicación off-Label en 765 prescripciones durante el periodo de estudio, identificándose al menos un medicamento prescrito con uso no incluido o indicación off-label. Según su acrónimo a nivel de la clasificación ATC, los pertenecientes a los tres niveles o grupos más destacados fueron los pertenecientes al grupo J con un 26,94%, grupo N 20,98% y el grupo C con un 16,68% de las prescripciones. Conclusiones: El mayor porcentaje de la población durante el periodo de estudio fue el primer año de vida. Los medicamentos con mayor número de prescripciones fueron el meropenem, la dipirona, salbutamol, espironolactona, enalapril, bromuro de ipatropio, la gentamicina, caspofungina, propanolol y tramadol.

Objective: To study the use of drugs with off-label indications in in-hospital pediatric patients in a third-level Clinic in the city of Barranquilla-Atlántico. Methodology: The design used in this study was observational, where the frequency of prescriptions and administration of drugs with an unapproved indication was obtained. The study was carried out in four phases, the first was the systematic search for drugs based on the scientific literature, in the second phase the patients were selected based on the inclusion criteria of the study, the third phase was the analysis and processing of the data and the fourth phase was the construction of the list of off-label drugs. Results: 204 patients from the Caribe and Pediatric ICU wards, who met the inclusion criteria, were followed during the three (3) month study period. 386 drugs with off-label indication were identified in 765 prescriptions during the study period, identifying at least one drug prescribed with use not included or off-label indication. According to its acronym at the level of the ATC classification, those belonging to the three most prominent levels or groups were those belonging to group J with 26.94%, group N 20.98% and group C with 16.68% of the prescriptions. Conclusions: The highest percentage of the population during the study period was the first year of life. The medications with the highest number of prescriptions were meropenem, dipyrone, salbutamol, spironolactone, enalapril, ipatropium bromide, gentamicin, caspofungin, propanolol and tramadol. (AU)

Objetivou-se testar a atividade inseticida de pós vegetais em Sitophilus zeamais. Foram testados os pós de Anadenanthera colubrina (folhas); Annona muricata (sementes); Azadirachta inidica (folhas e flores); Caesalpinia pyramidalis (folhas), Chenopodium ambrosioides (folhas e flores); Cymbopogon sp.(folhas); Cymbopogon citratus (folhas); Momordica charantia (folhas e frutos); Piper nigrum (sementes); e Ricinus communis (folhas). Além disso, avaliou-se o potencial inseticida de folhas e flores de C. ambrosioides em diferentes dosagens. Na avaliação de repelência foi estabelecido um índice de preferência, e utilizado o teste t para comparação das médias das espécies vegetais. Também foi realizada a comparação das médias das plantas que foram classificadas como repelentes. Para avaliação da mortalidade, procedeu-se a análise de variância e a comparação das médias pelo teste de Tukey e também o teste t para comparação das médias dos tratamentos C. ambrosioides e P. nigrum. Os dados de emergência foram analisados pelo teste de Tukey. Para avaliar os dados de mortalidade, ocasionados por C. ambrosioides, determinou-se a CL50 utilizando a análise de Probit. Os dados de emergência foram verificados pela análise de regressão. As plantas que provocaram repelência foram Cymbopogon sp., C. citratus e C. ambrosioides. A planta que mais afetou a sobrevivência da praga foi C. ambrosioides, que provocou mortalidade total dos insetos infestantes e nenhuma emergência. Adultos de S. zeamais são mais suscetíveis a concentração de 0,125 g do pó de C. ambrosioides.
Effect of plant powders on Sitophilus zeamais (Mots., 1855) (Coleoptera: Curculionidae). The objective of the present study was to test the insecticidal activity of vegetable powders on Sitophilus zeamais. Powders of Anadenanthera colubrina (leaves); Annona muricata (seed); Azadirachta inidica(leaves and flowers);Caesalpinia pyramidalis(leaves);Chenopodium ambrosioides (leaves and flowers);Cymbopogon sp. (leaves);Cymbopogon citratus (leaves); Momordica charantia (leaves and fruits);Piper nigrum (seed); andRicinus communis (leaves) were evaluated. In addition, we evaluated the insecticidal potential of leaves and flowers of C. ambrosioidesat different dosages. In the evaluation of repellency a preference index was established, and the t test was used to compare the means of plant species. The means of plants that were classified as repellent were also compared. To assess mortality, we proceeded with the analysis of variance and comparison of means by Tukey test and also the t test for comparing the means of the C. ambrosioides and P. nigrum treatments. The emergence data were analyzed by Tukey test. To evaluate the data on mortality caused by C. ambrosioides, the CL50 was determined using Probit analysis. The emergence data were verified by regression analysis. Plants that caused repellency were Cymbopogon sp., C. citratusand C. ambrosioides. The plant that most affected the survival of the pest wasC. ambrosioides, which caused total mortality of insect infestations and no adult emergence. Adults of S. zeamaisare most susceptible to the concentration of 0.125 g ofC. ambrosioides powder.

El síndrome compartimental se define como un aumento de las presiones en un espacio cerrado, lo que determina un compromiso en la perfusión tisular con el desarrollo de un cuadro de rabdomiolisis. Las causas pueden ser físicas, como una presión mantenida sobre una región anatómica, o bien asociarse al consumo de drogas de abuso, en especial la heroína. En este último caso se han implicado en la fisiopatología mecanismos tóxicos e inmunológicos. En el 30% de los cuadros de rabdomiolisis se desarrolla una insuficiencia renal aguda. Su tratamiento pasa por la reposición volémica eficaz, forzar la diuresis alcalina y la administración de furosemida y manitol, éstos últimos con ciertas precauciones. No se ha demostrado el beneficio de la dopamina.Ante un paciente heroinómano que presente un cuadro de tumefacción de extremidades, con o sin periodo de inconsciencia, se debe sospechar la presencia de síndrome compartimental
Compartment syndrome is a condition in which increased pressure within a limited space compromises tissue perfusion with the development of rhabdomyolysis. The causes can be physical, such as the pressure exerted on an anatomical region, or it can be associated with the consumption of illegal drugs, especially heroin. In this latter case, toxic and immunological mechanisms are involved in the physiopathology. Acute renal failure develops in 30% of cases of rhabdomyolysis. Its treatment includes efficient volume replacement, forcing urinary alkalinization and the administering of furosemide and mannitol, with certain precautions. No benefit has been shown in dopamine. When a heroin addict patient shows a clinical pattern of tumescence of his extremities, with or without a period of unconsciousness, the presence of compartment syndrome is to be suspected

The breeding structure of both colony and population of social insects can be examined by genetic analysis. Colonies of the leaf-cutting ants Acromyrmex heyeri and A. striatus (Myrmicinae, Attini) were thus analyzed for isoenzyme systems MDH, a-GPDH, and AMY to describe genotype variability and social structure. A total of five loci were investigated (three for amylase and one for each other system). Ninety-seven colonies of A. heyeri and 103 of A. striatus were sampled in different localities in Southern Brazil (State of Rio Grande do Sul). The genotypes found show the occurrence of monogyny and polygyny associated or not with polyandry, which indicates that the social organization is colony-specific. The polygyny and polyandry observed are likely to be responsible for the great genotypic diversity of the colonies. The average inbreeding coefficient per colony was higher in A. striatus than in A. heyeri, which may reflect the different patterns of production of sexual individuals and nuptial flight of those two species

Adultos de Eurema elathea foram estudados semanalmente (1992-1994) em seis locais (dormitórios), ao redor de um fragmento de mata em uma fazenda e em dois locais na área urbana de Uberlândia, MG. Os machos foram classificados em seis categorias fenotípicas, as quais variam desde a presença de uma grande e conspícua barra preta na margem interna dorsal da asa anterior (forma escura da estação úmida) até a ausência da barra (forma clara da estação seca). A massa corporal e a área da asa foram comparadas: formas diferentes mostraram médias similares. A abundância das borboletas e a freqüência das formas variaram conforme a umidade (chuvas). Na estação úmida, os indivíduos foram menos freqüentes e monomorficamente escuros, enquanto na seca, a população aumenta e as formas claras predominam. As taxas de recaptura e recrutamento são comparadas com outras borboletas que se agregam durante a noite. O potencial de dispersão foi similar entre os sexos e variou sazonalmente, sendo que a população é mais sedentária no período seco. O máximo tempo de residência registrado foi de 91 dias para uma fêmea e de 84 dias para um macho. A fração de indivíduos que se moveram de um sítio de descanso para outro foi similar em ambos os sexos e formas de machos, mas foi significativamente maior na fazenda em relação à área urbana. Da mesma forma, foi recapturada uma fração significativamente maior (21,3) de borboletas marcadas na área urbana do que na fazenda (15,6), sugerindo modificação comportamental para o sedentarismo nos indivíduos urbanos. São discutidas as forças seletivas que moldam o hábito de descanso gregário em E. elathea e em outras borboletas, e propõe-se uma estratégia protocooperativa de economia de energia.

Three species of flatworms from the genus Echinococcus (E. granulosus, E. multilocularis and E. vogeli) and four strains of E. granulosus (cattle, horse, pig and sheep strains) were analysed by the PCR-SSCP method followed by sequencing, using as targets two non-coding and two coding (one nuclear and one mitochondrial) genomic regions. The sequencing data was used to evaluate hypothesis about the parasite breeding system and the causes of genetic diversification. The calculated recombination parameters suggested that cross-fertilisation was rare in the history of the group. However, the relative rates of substitution in the coding sequences showed that positive selection (instead of purifying selection) drove the evolution of an elastase and neutrophil chemotaxis inhibitor gene (AgB/1). The phylogenetic analysis revealed several ambiguities, indicationg that the taxonomic status of the E. granulosus horse strain should be revised.

El dolor es un síntoma de alta prevalencia en los pacientes con cáncer y deteriora de forma importante su calidad de vida. Con las medidas enunciadas por la OMS en 1986, que divide en tres escalones ascendentes las distintas opciones terapéuticas de las que disponemos, el dolor puede ser controlado en un alto porcentaje de casos. Aquellos pacientes difíciles de controlar con estas medidas, se pueden beneficiar de la aplicación de técnicas de neuromodulación por expertos en el tratamiento del dolor crónico. El correcto manejo de los distintos fármacos (AINES, opiáceos y coadyuvantes), el conocimiento de sus efectos secundarios, la pérdida del miedo a los opiáceos y el conocimiento de los distintos síndromes álgicos asociados al paciente oncológico, deben ir de la mano con la adecuada valoración del dolor según las distintas escalas, tanto en la fase de instauración del tratamiento, como en el seguimiento del paciente (AU)
Pain is a symptom with a high prevalence in patients with cancer and causes an important deterioration in their quality of life. With the measures laid out by the WHO in 1986, which divides the different therapeutic options available in three ascending steps, pain can be controlled in a high percentage of cases. Those patients who are difficult to control with these measures can benefit from the application of neuromodulation techniques by experts in the treatment of chronic pain. The correct employment of the different medicines (non-steroidal anti-inflammatory medicines, opiates and coadjuvants), knowledge of the secondary effects, loss of fear in the face of opiates and knowledge of the different algic syndromes associated with the oncology patient, must be accompanied by a suitable evaluation of the pain according to the different scales, both in the phase of the treatment's initiation and in the follow-up of the patient (AU)

F1-antigen purified from Yersinia pestis was covalently linked to 5-mm diameter filter paper discs plasticized with polyvinyl alcohol-glutaraldehyde. These discs were used both for ELISA and dot-ELISA for the detection of anti-F1 IgG in rabbits. The best conditions were achieved using 1.25 µg of F1 antigen/disc, 3 percent w/v skim milk in PBS as blocking agent, anti-IgG peroxidase conjugate diluted 12,000 times, and serum from rabbits immunized or not against Y. pestis, diluted 6,400 times. The absorbance values obtained from the comparative study between this procedure and conventional ELISA were not significantly different but the low cost of the reagents employed in ELISA using the filter paper discs plasticized with polyvinyl alcohol-glutaraldehyde makes this method economically attractive.

Antigen from Yersinia pestis was adsorbed on cellulose acetate discs (0.5 cm of diameter) which were obtained from dialysis membrane by using a paper punch. ELISA for human plague diagnosis was carried out employing this matrix and was capable to detect amount of 1.3 µg of antigen, 3,200 times diluted positive serum using human anti-IgG conjugate diluted 1:4,000. No relevant antigen lixiviation from the cellulose acetate was observed even after washing the discs 15 times. The discs were impregnated by the coloured products from the ELISA development allowing its use in dot-ELISA. Furthermore, cellulose acetate showed a better performance than the conventional PVC plates.

The effects of stage of lactation, parity and breed on the somatic cell count were studied in 68 female Saanen, Anglo-Nubian and Pardo Alpine goats. The animals were assisted during seven months and bacteriologically negative milk samples were submitted to somatic cell count (SCC). Significant effects (P<0.05) of stage of lactation, parity and breed on SCC were observed, with higher values being obtained in late lactation and in goats with four or more parturations. The SCC mean was 0.95x10 elevada a sexta potência cel/ml. The mean values of cell count observed indicate that physiological factors interfere in cell count of the udder
