Revisión metodológica para escribir y publicar casos clínicos: aplicaciones en el ámbito de la nutrición

Introducción: en la actualidad, los casos clínicos suponen una importante herramienta docente con aplicaciones prácticas y contribuyen a la expansión del conocimiento de los profesionales de la salud. Objetivos: revisar la metodología de elaboración de casos clínicos, mostrando las similitudes y diferencias en los criterios de formato y contenido que son solicitados para que los reportes de casos sean publicados. Metodología: revisión bibliográfica en PubMed y Scielo entre 2005-2015, y rastreo manual de aquellas referencias más relevantes de los artículos seleccionados. Criterios de inclusión: artículos originales/revisiones bibliográficas en inglés/español/portugués publicados en cualquier país y que incluyan guías o recomendaciones sobre la redacción de casos clínicos. Resultados: se encontraron 131 artículos, de ellos, 20 cumplieron los criterios de inclusión, añadiendo cinco artículos por rastreo manual. Las variables descritas fueron: objetivo, recomendaciones y conclusiones, presentadas en tres tablas: 1. Publicaciones referentes internacionales; 2. Revistas internacionales y 3. Revistas latinoamericanas. Discusión: existen referentes internacionales que proporcionan directrices muy concretas cuando se precisa escribir y publicar un caso clínico. Tanto los referentes internacionales como las recomendaciones analizadas son coincidentes en su utilidad, aunque no existe una estandarización en su metodología. Son muy pocas las directrices que mencionan incluir el tratamiento dietético, el seguimiento y la evolución del mismo durante la situación clínica. Conclusiones: se recomienda a los autores interesados en describir un caso clínico cuyo tratamiento sea principalmente nutricional, seguir una guía ajustada a la situación clínica a presentar, siendo la guía CARE una buena opción.

Interaction between diurnal variations of intraocular pressure, pachymetry, and corneal response to an air puff: Preliminary evidence

Diurnal changes in corneal geometry, pachymetry, and intraocular pressure (IOP) in a healthy eye were recorded. The deformation response to an air puff was simulated using 3 levels of corneal stiffness. The response was dependent on IOP and pachymetry and not only on the biomechanical properties of the cornea. Similarly, the maximum variability due to the diurnal changes in pachymetry and IOP in the corneal displacement generated by the air puff was found to reach 5%. Therefore, diurnal changes in IOP and corneal thickness were able to induce some variability in the air puff–based corneal deformation response. This potential variability should be considered when the biomechanical properties of the cornea are analyzed with air-puff devices.

Management of subluxated cataract with capsule anchor implantation

We describe a small case series that provides preliminary evidence of the usefulness of a new capsule-anchoring device for the management of subluxated cataracts. Three eyes of 3 patients with traumatic subluxated cataract causing a significant visual loss were enrolled. Phacoemulsification was performed in all cases with implantation of a capsule-anchoring device (AssiAnchor) because partial zonular dehiscence was present. A significant visual improvement was achieved in the 3 cases. The capsular bag was well centered and the anchors firmly attached to the capsulorhexis and sclera at 12 months postoperatively. The capsule-anchoring device was helpful in managing traumatic subluxated cataracts, enabling effective centration of the intraocular lens–capsular bag complex and, consequently, effective visual restoration.

Assessment of corrective measures for alleviating slope instabilities in carbonatic Flysch formations: Alicante (SE of Spain) case study

As is well known, in order to select remediation measures to correct or prevent slope instabilities, it is essential to identify and characterize the instability mechanisms. This task is especially complex for heterogeneous rock masses such as Flysch formations. This paper addresses the assessment of corrective measures used in carbonate Flysch formations by classifying and grouping field data reported in an available database in order to associate this data with various instability mechanisms and stratigraphic column types as well as with the corrective measures taken to stabilise them. For this purpose, 194 slopes have been geomechanically characterized, mainly by considering the observed instability mechanisms. The corrective measures that were applied have been evaluated for their suitability and performance, and, if applicable, the causes of their malfunction have been also studied. As a result, some guidelines based on the observed behaviour and the suitability of the correction measure as a function of instability type are proposed for similar slopes.
