ABSTRACT
BACKGROUND: fibre is effective in some types of constipation. Our objective was to determine if the administration of an enriched dairy preparation with a supplement of soluble fibre (Naturfibra) [inulin and digestion resistant maltodextrin (Fibersol 2)], improves primary chronic constipation. METHODS: Prospective, randomized, double blind clinical trial randomized with dietary intervention in 32 subjects with constipation according to the Rome II criteria. Thirty two subjects (men 4; women 28) with an average age of 47 +/- 15 years were randomly divided in two homogeneous groups. A type of milk (A or B) was assigned to each group. Group A received fibre enriched semi-skimmed milk; Group B received semi skimmed milk. The subjects drank half a litre of milk per day during 20 days, meaning that those who drank the enriched milk ingested 20 grams of fibre a day. RESULTS: The subjects that presented straining at defecation (p < 0.001), sensation of incomplete evacuation (p < 0.001), sensation of obstruction in the evacuation (p < 0.001) and days between bowel movements, diminished significantly after the intake of milk supplemented with fibre. CONCLUSION: The intake of a dairy preparation with a supplement of fibre containing 20 grams of soluble fibre (inulin and digestion resistant maltodextrin), improves the situation of idiopathic primary chronic constipation based on the Rome II criteria.

UNLABELLED: This study aims to evaluate how rehydration beverage ingestion influences gastric emptying rate (in cycle ergometer) at rest and during exercise at 70 % of maximal oxygen consumption (VO2max). MATERIAL AND METHOD: 26 well-trained cyclists performed a preliminary maximal test until exhaustion to evaluate their VO2max, and two submaximal exercise tests at 70 % of their mode-specific VO2max. Each test was separated by one week. During the two submaximal tests, cyclists consumed 200 ml of a 99mTc-DTPA labeled rehydration beverage (A or B) and scintigraphy determinations were performed at rest. After, exercise was initiated for 60 minutes with an intake rate of 200 ml every 15 minutes, making gastric serial scintigraphy determinations. The difference regarding chemical composition between A and B drinks resides in the fact that drink A contains a smaller load in carbohydrates (10.3 g/100 ml versus 15.2 g/100 ml of B), proteins in form of serum milk and antioxidants in form of fruit juice. Both contain ions and vitamins. RESULTS: at rest, gastric count number was significantly reduced (p > 0.000) from 0 to 25 minutes for both A and B beverage. At the end of exercise (60 min), there was greater gastric retention for B beverage than for A, this difference being statistically significant (p < 0.031). CONCLUSIONS: The A beverage, a rehydration drink on the market with protein and antioxidants with fruit juice content, has a faster gastric emptying rate than the B sport beverage.

OBJECTIVE: To evaluate improvement in therapeutic management of allergic rhinitis. DESIGN: Study of level of quality (longitudinal, prospective, intervention). SETTING: Primary care. PATIENTS AND OTHERS PARTICIPANTS: First evaluation (second quarter of 1995): 73 out of 305 patients were sampled (confidence 5%, accuracy 10%). Second evaluation (second quarter of 1996). Sample of 51 patients from a total of 210. INTERVENTIONS: Explicit criteria and standard procedure, based on consensus, for rhinitis treatment and an overall indicator of the general quality of rhinitis management were analysed. Criterion 1 (C1): correctly scaled treatment; criterion 2 (C2): initial treatment of choice with inhaled corticoids; criterion 3 (C3): correct use of oral corticoids or immunotherapy; criterion 4 (C4): coadjutant therapy according to predominant symptoms. Corrective measures: ongoing training and routine use of guide to practice. STATISTICS: index of compliance with criteria, Chi squared and Fisher's Z tests of a tail to compare both evaluations. MEASUREMENTS AND MAIN RESULTS: First evaluation: index of compliance with C1 = 59% (CI +/- 11), C2 = 41% (CI +/- 11), C3 = 90% (CI +/- 6) and C4 = 83% (CI +/- 8). Criteria and summary indicator obtained better results in patients attended by allergists. Second evaluation with overall improvement: C1 = 68.6% (CI +/- 13), C2 = 57% (CI +/- 13), C3 = 94% (CI +/- 6), C4 = 98% (CI +/- 3). Significant differences for C4 and C2 (p < 0.05). Overall quality and quality of criteria improved for patients attended in our environment. The summary indicator went up from 35.6% to 57% (p = 0.019), with the quality levels (C1-C4) becoming the same as those of the patients with allergy attended and with significant differences in the first evaluation disappearing. CONCLUSIONS: Ongoing training and routine use of guides to practice enables the therapeutic management of allergic rhinitis in primary care to be improved.

Pacientes u otros participantes. Primera evaluación (segundo trimestre de 1995): entre 305 pacientes se muestrearon 73 (confianza, 5 por ciento; precisión, 10 por ciento). Segunda evaluación (segundo trimestre de 1996). Tamaño muestral de 51 pacientes de un total de 210.Intervenciones. Se analizaron criterios explícitos y normativos de proceso basados en consenso de tratamiento de rinitis y un indicador resumen de calidad de manejo global. Criterio 1 (C1): tratamiento correctamente escalonado. Criterio 2 (C2): tratamiento inicial electivo con corticoides inhalados. Criterio 3 (C3): correcta utilización de corticoides orales o inmunoterapia. Criterio 4 (C4): terapia coadyuvante según síntomas predominantes. Medidas correctoras: formación continuada y uso rutinario de guía para la práctica. Estadística: índice cumplimiento criterios, 2 y Z de Fisher con test de una cola para comparar ambas evaluaciones. Mediciones y resultados principales. Primera evaluación: índice cumplimiento C1 = 59 por ciento (IC ñ 11); C2 = 41 por ciento (IC ñ 11); C3 = 90 por ciento (IC ñ 6), y C4 = 83 por ciento (IC ñ 8). Los criterios y el indicador resumen obtuvieron mejores resultados en los pacientes atendidos por alergólogos. Segunda evaluación con mejora global: C1 = 68,6 por ciento (IC ñ 13); C2 = 57 por ciento (IC ñ 13); C3 = 94 por ciento (IC ñ 6), y C4 = 98 por ciento (IC ñ 3). Diferencias significativas para C4 y C2 (p < 0,05). La calidad global y de criterios mejoró entre los pacientes atendidos en nuestro ámbito. El indicador resumen pasó del 35,6 por ciento al 57 por ciento (p = 0,019), igualándose los niveles de calidad (C1-C4) a los de pacientes atendidos en alergia y desapareciendo las diferencias significativas de la primera evaluación. Conclusiones. La formación continuada y la utilización rutinaria de guías para la práctica permite mejorar el manejo terapéutico de la rinitis alérgica en atención primaria. (AU)
