Purpose: The aim of this study was to evaluate the efficacy artificial intelligence–derived morphometric parameters in characterizing Fuchs corneal endothelial dystrophy (FECD) from specular microscopy images. Methods: This cross-sectional recruited patients diagnosed with FECD, who underwent ophthalmologic evaluations, including slit-lamp examinations and assessments using microscopy. modified Krachmer grading scale used for clinical FECD classification. images were processed a...
Introducción: la colitis ulcerativa pediátrica (CUP), enfermedad de Crohn (ECP) y inflamatoria intestinal no clasificable (EIIPNC) tienen particularidades clínicas psicosociales que las diferencian del adulto pueden condicionar enfoques terapéuticos distintos por posibles repercusiones nutricionales, crecimiento desarrollo, lo representa un desafío para el pediatra gastroenterólogo. Objetivo: desarrollar recomendaciones basadas en evidencia consenso expertos diagnóstico tratamiento oportunos...
En Colombia no hay datos acerca de la percepción calidad vida (CdV) en enfermedad inflamatoria intestinal (EII). Se plantea como objetivo determinar CdV mediante el cuestionario IBDQ-32 pacientes con EII a partir una muestra diferentes centros referencia. realizó un estudio corte transversal adultos, remisión clínica, seguimiento ambulatorio, 3 instituciones ciudades, entre junio 2022 noviembre 2022, se identificaron sujetos elegibles, recolectó información fechas distintas, aspectos...
Antecedentes: las manifestaciones extraintestinales (MEI) son comunes en niños y adultos su presencia se asocia con mayor gravedad la enfermedad inflamatoria intestinal (EII). En pediatría, los estudios escasos Latinoamérica no existen Colombia. Objetivo: describir prevalencia de MEI EII características demográficas, clínicas bioquímicas asociadas. Metodología: estudio retrospectivo pacientes diagnosticados inicio pediátrico entre 2007 2022 atendidos una institución Bogotá. Se realizó un...
Corneal endothelium assessment is carried out via specular microscopy imaging. However, automated image analysis often fails due to inadequate quality conditions or the presence of dark regions in pathologies such as Fuchs' dystrophy. Therefore, an early reliable classification strategy required before evaluation based on cell segmentation. Moreover, conventional approaches rely manually labeled data which are difficult obtain. We propose a two-stage semi-supervised algorithm, feature...
This paper describes a corneal endothelial image segmentation strategy based on deep regression of signed distance map (UNet-dm) compared to classical pixel-wise classification (UNet-Mask). The proposed approach generates cell masks closer reference masks, improving the mapping well-defined and guttae boundaries. results reveal enhanced morphometric parameters that align values. study emphasizes new technique for continuous segmentation, employing UNet model, demonstrating its promise...
