Hemangioma cavernoso como causa de hemorragia digestiva oculta manifiesta: reporte de caso / A Case Report of Cavernous Hemangioma as a Cause of Occult Gastrointestinal Bleeding

Resumen Se realizó un estudio descriptivo tipo reporte de caso de un paciente valorado por el servicio de gastroenterología en la Clínica Nuestra en la ciudad de Cali, por sospecha de sangrado digestivo oculto cuyos estudios previos no habían mostrado causa de sangrado. Se realizó videocápsula endoscópica (MiroCam®) con un hallazgo positivo de lesión en el intestino delgado. Se llevó a enteroscopia en Clínica Farallones de la Ciudad de Cali con enteroscopio Olympus 180 Q que confirmó el hallazgo. Ulteriormente, se llevó a cirugía, en la que se confirmó el diagnóstico. Los datos y las fotografías se obtuvieron en bases de datos de los servicios de endoscopia y las fotos de patología se obtuvieron del registro del médico patólogo. Finalmente, se realizó una búsqueda en PubMed sobre literatura existente de historia clínica y reportes de casos similares.

Abstract This is a descriptive study based on the case report of a patient suspected of occult gastrointestinal bleeding who was evaluated by the gastroenterology service in Clínica Nuestra in Cali. Previous studies had not shown cause of bleeding. Video endoscopy (Mirocam) found a lesion in the small intestine. Enteroscopy at performed at Clínica Farallones in Cali with an Olympus 180 Q enteroscope confirmed the finding. Surgery further confirmed the diagnosis. Data and photographs were obtained from the database of endoscopy services and the pathology photos were obtained from the pathologist's registry. A literature review based on a Pubmed search of the existing literature on clinical histories and reports of similar cases is included.

Effect of a mouthrinse containing triclosan and a copolymer on plaque formation in the absence of oral hygiene.

Twenty male and female adult subjects were entered into a 7-week, double-blind clinical study to determine the effect on plaque formation of a mouthrinse containing 0.03% [corrected] triclosan and 0.25% of a copolymer of methoxyethylene and maleic acid, as compared to 1) a water placebo mouthrinse, 2) a matching alcohol placebo mouthrinse, and 3) Plax antiplaque pre-brushing dental rinse. The subjects were stratified according to their initial plaque scores and assigned in a type of randomized block design (repeated Latin square), so that each subject received each of the four mouthrinses only once for 1 week during the study. The subjects did not use any other oral hygiene procedure (including use of a toothbrush and dentifrice) during the 1-week period of time when they rinsed with their assigned mouthrinse product. The results indicated that use of the triclosan/copolymer mouthrinse provided a 49.8% reduction in supragingival plaque formation compared to the water placebo mouthrinse. The difference was statistically significant at the 99% level of confidence (P less than .01). Similarly, the use of the triclosan/copolymer mouthrinse provided a 47.6% reduction in supragingival plaque formation compared to Plax antiplaque pre-brushing dental rinse. The difference was statistically significant at the 99% level of confidence (P less than .01). The results further indicated that use of the triclosan/copolymer provided a 31.2% reduction in supragingival plaque formation compared to the alcohol placebo mouthrinse. The difference was statistically significant at the 99% level of confidence (P less than .01).
