[Corneal melting and topical nonsteroidal anti-inflammatory drug (NSAID). A case report]. / Relación entre anti-inflamatorios no esteroideos (AINES) y queratolisis. A propósito de un caso.

PURPOSE: To study the relationship between the use of nonsteroidal anti-inflammatory drug (NSAID) and the corneal melting. CASE REPORT: We report a case of keratolysis after vitreoretinal surgery and topical use of ketorolac tromethamine (Acular). DISCUSSION: It is proposed the multifactorial etiology in the cases of corneal melting related to the use of NSAID and it is recommended an reasonable use of them in each situation and to check the possible comorbility of other agents.

Energy evaluation of forest residues originated from pine in Galicia.

Pine residues originated from cuts and forestry tasks were studied with the main objective of using them as an alternative source of energy. Calorific values were measured using a static bomb calorimeter in an oxygen atmosphere. From these measurements a value of 7500 kJkg(-1) for the mean lower heating value of these kind of residues was found. A rational and sustainable exploitation of the calorific energy contained in these residues can yield a gross benefit of 2.8 x 10(8) per year through its transformation in electric energy. The study was made along one year, using samples collected in different previously characterized zones. Some other parameters such as: elementary composition, heavy metal content, flammability, and bioclimatic properties were also determined.
