RESUMO
PURPOSE: The aim of this study was to elucidate whether intrasynovial corticosteroid injections for trigger digit reduced the volume of the tendon and pulley on high-resolution ultrasonography. METHODS: Twenty-three digits of 20 patients with trigger digit were included. Each affected finger was graded clinically according to the following classification: grade I for pre-triggering, grade II for active triggering, grade III for passive triggering, and grade IV for presence of contracture. Axial ultrasound examinations were performed before an intrasynovial corticosteroid injection and at an average of 31 days after the injection. The transverse diameter, thickness, and cross-sectional area of the tendon and the thickness of the pulley were measured by two independent, blinded researchers. RESULTS: At least 1 grade of improvement was achieved in this study group by the time of the second examination. The transverse diameter and cross-sectional area of the tendon and the thickness of the pulley significantly decreased (P < 0.05). CONCLUSION: The injection of a single dose of betamethasone improved clinical symptoms by reducing the volume of both the tendon and pulley, which may be related to the fact that tendon and pulley ruptures are delayed by corticosteroid injections.

En este artículo propone que los indicadores estratégicos para los países menos desarrollados deben considerar las especificidades de estos países de ahí que no se trata tan sólo de reproducir los indicadores utilizados por la Organización para la Cooperación y el Desarrollo Económico. Con este objetivo, en el presente trabajo se utiliza un nuevo marco conceptual que demuestra la importancia de un equilibrio entre la eficiencia económica y el bienestar social. Se enumeran varios motivos razonables para desarrollar indicadores estratégicos, se demuestran cómo cada uno de ellos se basan en suposiciones no necesariamente válidas para todos los países y fundamenta la necesidad de adoptar un nuevo enfoque conceptual. Después de discutirse las características principales del modelo propuesto, se demuestra de qué manera este nuevo marco puede ayudar a identificar los tipos de indicadores necesarios. Finalmente se sugiere cómo el enfoque pudiera también ser útil para un proyecto orientado a evaluar publicaciones científicas.
This paper propounds that strategic indicators for less developed countries should take into consideration the specificities of these countries, hence should not just replicate the indicators used by the OECD. With this purpose, it uses a new conceptual framework stressing the importance of a balance between economic efficiency and social welfare. It lists several sensible reasons to develop strategic indicators, shows how each of them is based on assumptions that are not necessarily valid to all countries, and shows why a new conceptual approach is needed. Then, after discussing the main features of the proposed model, it shows how the new framework can help identifying the kinds of new indicators needed. Finally, the paper suggests how the approach could also be useful to a project trying to evaluate scientific publications.
