Clinical Trial
Intermittent suction of oral secretions before each positional change may reduce ventilator-associated pneumonia: a pilot study.
That ventilator-associated pneumonia (VAP) can be reduced by continuous and/or intermittent subglottic suction highlights the importance of clearance of oropharyngeal secretions. We prospectively evaluated the usefulness of intermittent suction of oral secretions before each positional change in reducing VAP. ⋯ Intermittent suction of oral secretions before each positional change may reduce VAP occurrence in ICU patients.

African-Americans have been underrepresented in most large Crohn's disease (CD) trials. This study was undertaken to assess the course and character of CD in African-Americans in comparison with whites. ⋯ These data lend credence to the suggestion that the nature of CD may be different in African-Americans compared with whites. However, despite this apparent difference in disease manifestation, the contribution of socioeconomic factors, access to health care, and understanding of the disease likely play a role as well.

To evaluate the efficacy of cyanocobalamin treatment in patients having recurrent aphthous ulcers (RAUs) with normal or decreased serum vitamin B12 (cobalamin) levels. ⋯ Cyanocobalamin treatment maybe beneficial for patients with RAU even when serum cobalamin levels are normal. We suggest that higher serum cobalamin levels should be attained in patients with RAU for mucosal protection.
