[Rituximab as rescue therapy in refractory esophageal lichen planus].

Esophageal lichen planus (ELP) is a rare condition with unknown prevalence that can sometimes be underestimated due to the subtle and nonspecific findings of diagnostic workup. Oral lesions rarely extend to the esophageal mucosa, but when they do, the most frequent symptoms are dysphagia and odynophagia. There is often a significant delay in diagnosis and inadequate treatment.

[High incidence rates of inflammatory bowel disease in Navarra (Spain). Results of a prospective, population-based study].

Introduction: As reflected in the European Collaborative Study on Inflammatory Bowel Disease (1991-1993), differences between northern and southern European countries in the incidence of ulcerative colitis (UC) and Crohn's disease (CD) show a tendency to decrease. No data are available on the current incidence of these diseases in Navarre (northern Spain).

Aim: To determine the present incidence of inflammatory bowel disease (IBD) in Navarra.
