[Ulcerative colitis associated with autoimmune hepatitis: a differential form of inflammatory bowel disease?]. / Colitis ulcerosa asociada a hepatitis autoinmune: ¿una forma diferencial de enfermedad inflamatoria intestinal?

Inflammatory bowel Disease (IBD) is a group of chronic inflammatory diseases that can be associated with different autoimmune diseases, including autoimmune hepatitis (AIH). Some specific and differential characteristics in children with IBD associated to AIH have been described. Our aim is to describe the clinical pattern of this association observed in our patients, confirming its differential characteristics as compared to classical IBD in children.

[Spanish version of the CAM-ICU (Confusion Assessment Method for the Intensive Care Unit). Pilot study of validation]. / Versión en español del método para la evaluación de la confusión en cuidados intensivos, estudio piloto de validación.

OBJECTIVE: To validate the Spanish version of the CAM-ICU. DESIGN: Validation study. The inter-rater reliability and validity were evaluated using a blind comparison with the DSM-IVTR criteria (reference standard) in a group of patients hospitalized in an Intensive Care Unit (ICU). SETTING: Medical-surgical ICU. PATIENTS: 129 adults with RASS >-4 score, within the 24-48 h of ICU admission. Independent application of the CAM-ICU by two intensive care specialists and evaluation by a psychiatrist using the DSM-IVTR criteria for delirium. RESULTS: Prevalence of delirium in the sample was 26.4%, this being and 48.3% in the 29 patients who received mechanical ventilation. Inter-rater reliability in the whole sample according to the Kappa index was 0.792 (95% CI 0.662-0.922, p<0.001) and in those who received mechanical ventilation was 0.726 (95% CI 0.487-0.965, p<0.001). The sensitivity, specificity, positive predicted value (PPV), negative predicted value (NPV), positive likelihood ratio (+LR), and negative likelihood ratio (-LR) were 79.4% (95% CI 63.2-89.7%); 97.9% (95% CI 92.6-99.4%); 93.1% (95% CI 78.0-98.1%); 93.0% (95% CI 86.3-96.6%); 37.72 (95% CI 9.47-150.20) and 0.21(95% CI 0.11-0.41), respectively, in the whole sample. In mechanically-ventilated patients, sensitivity, specificity, PPV, NPV, +LR and -LR were 92.9% (95% CI 68.5-98.7%); 86.7% (95% CI 62.1-96.3%); 86.7% (95% CI 62.1-96.3%); 92.9% (95% CI 68.5-98.7%); 6.96(95% CI 1.90-25.51) and 0.08 (95% CI 0.01-0.55), respectively. CONCLUSION: The Spanish version of the CAM-ICU is reliable. Its sensitivity, specificity and predictive values should be considered good.
