A trial was conducted in a commercial Citrus sinensis L. variety 'Washington' navel orange orchard to compare the coverage and efficacy against citricola scale Coccus pseudomagnoliarum (Kuwana) (Hemiptera: Coccidae) of 45.5 liters/ha of an nC24 agricultural mineral oil treatment applied by two different methods: a conventional air blast sprayer and a rotary atomizer. Three water volumes (2,340, 4,680, and 7,020 liters/ha) were applied with the air blast sprayer to determine the optimal spray volume for that equipment. A single volume (2,340 liters/ha) was applied with the rotary atomizer to compare its effectiveness with that of the air blast sprayer at this same volume. Results demonstrated that all treatments reduced citricola scale densities. Moreover, all treatments conducted with the air blast sprayer provided significantly greater coverage and significantly reduced citricola scale densities compared with the treatment made with the rotary atomizer. Larger water volume applications with the air blast sprayer did not significantly reduce citricola scale densities, although significantly better coverage was attained in the interior of the tree when spraying with 4,680 and 7,020 liters/ha. As a consequence, this study demonstrated that the increased coverage obtained by applying higher water volume with the air blast sprayer was not required for an optimal treatment in August, when the citricola scale population consisted of nymphs inhabiting the outside leaves of the tree.

Introducción. El remifentanilo presenta unas características farmacocinéticas que le permiten variar rápidamente sus acciones farmacológicas en respuesta a los cambios de la infusión. Comparamos la eficacia y seguridad de remifentanilo frente a fentanilo, en el postoperatorio inmediato de cirugía cardíaca (CC). Método. Estudio prospectivo, observacional, en pacientes consecutivos. Se estudian 2 grupos de tratamiento: remifentanilo a 0,1-0,2 µg/kg/min y fentanilo 30 µg/h, durante 5 h. Se analizan el nivel de confort, la solicitud de analgesia por parte del paciente (SA) y tiempo hasta solicitarla (TA).Se cuantifican el dolor según escala numérica del 1-10 al despertar (E1), a los 30 min (E2), 2 (E3) y 4 h postextubación (E4), los fracasos terapéuticos, los efectos adversos atribuibles a los opiáceos y la evolución general. Resultados. Se estudió a 74 pacientes (37 del grupo remifentanilo y 37 del grupo fentanilo). El 71,2 por ciento se encontró confortable (más en el grupo fentanilo: 86 frente a 55 por ciento). El número de bolos y dosis totales de opiáceos y otros analgésicos fue similar en ambos grupos, excepto tramadol (fue mayor en el grupo de remifentanilo). El fentanilo mostró controlar mejor el dolor en la escala numérica y con mayor diferencia cuanto mayor era el tiempo desde el ingreso en la unidad: E1, 3,23 frente a 3,03 (p < NS); E2, 4,5 frente a 5 (p < 0,005); E3, 4,2 frente a 2,5 (p < 0,001); E4, 4,2 frente a 2,1 (p < 0,01), en los grupos remifentanilo frente a fentanilo, respectivamente. Dos pacientes del grupo remifentanilo presentaron efecto "naloxona-like"; en la evolución general, no presentaron diferencias significativas. No se produjeron fracasos terapéuticos. El tiempo hasta la extubación fue más corto en el grupo remifentanilo (7,6 frente a 8,9 h), pero sin diferencia significativa. El tiempo de estancia en la Unidad de Cuidados Intensivos fue similar. Conclusiones. La analgesia proporcionada con una infusión de "transición" de remifentanilo durante el postoperatorio inmediato de CC es factible, pero en nuestra serie, el fentanilo mostró un mejor control analgésico postoperatorio, probablemente en relación con su distinto perfil farmacocinético. Ambos fármacos mostraron un buen perfil de seguridad, sin presentar efectos adversos graves. La fugacidad de los efectos del remifentanilo obliga a realizar una mayor vigilancia, al conocimiento de la farmacodinamia y al entrenamiento en su uso (AU)

PURPOSE: To evaluate and establish a relationship between serum ferritin value and haemoglobin level, serum iron or transferrin in volunteer blood donors. MATERIAL AND METHODS: We have studied a group of 479 blood donors from Navarra's Health Area V, whose blood cell examination, iron, ferritin and transferrin values were determined. We classified these donors in 4 groups according to their ferritin concentration (ng/mL): f1 (0-12), f2 (13-20), f3 (21-400) and f4 (more than 400). The results were analyzed by the statistical program SPSS/PC+. The sensitivity, specificity, accuracy and predictive value of the positive test, for the determination of haemoglobin level as an indicator of iron deposits were calculated. RESULTS: The comparative statistical study of all these groups indicated that there were significant differences in the ferritin and the haemoglobin values (p < 0.001 and p < 0.05, respectively), except between f1 and f2, which only presented and intergroup difference in the ferritin values. In blood donors, the estimation of iron deposits from the hemoglobin level showed a diagnostic sensitivity greater than 90%. CONCLUSIONS: Haemoglobin values would allow the selection of those donors that could have an iron deficiency, or a borderline concentration; nevertheless, it would not allow the distinction between these two groups. This last observation is not important because donors that show a ferritin value lower than 20 ng/mL should not give blood. When the ferritin is greater than 20 ng/mL in men, the iron deposits will be adequate in 97% of them. This percentage is about 90 in women whose haemoglobin level is greater than 12.5 g/dL. Therefore, we consider that haemoglobin values present a good cost/benefit ratio for donor selection.
