Pleural Disease/Pleural Effusion PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: This study tries to determine the usefulness of the cholesterol in differentiating transudative and exudative pleural effusion, to value its usefulness to distinguish pleural benign effusion from malignant, and to identify the meaning of high levels of cholesterol in pleural fluid. ⋯ The following authors have nothing to disclose: Rosa Mirambeaux Villalona, Esteban Perez Rodriguez, Paola Arrieta Narvaez, Carolina Gotera, Carolina Jurkojc Mohremberger, Deisy Barrios Barreto, Patricia Lazo Meneses, Salvador Diaz Lobato, Sagrario Mayoralas AlisesNo Product/Research Disclosure Information.

Pulmonary Function TestingSESSION TYPE: Slide PresentationsPRESENTED ON: Sunday, March 23, 2014 at 04:15 PM - 05:15 PMPURPOSE: Exhaled nitric oxide (FeNO) and Methacholine challenge (MCH) are both utilized in the detection and management of numerous pulmonary diseases. MCH is a measure of direct airway hyperresponsiveness. FeNO measures bronchial epithelial damage from eosinophilic bronchitis whether asthma or non-asthma related. FeNO has an attractive performance profile, as it is a cheaper and less invasive test. We hypothesize that FeNO can decrease the need for MCH testing. ⋯ The following authors have nothing to disclose: Andrew Nickels, Kenneth Parker, Paul Scanlon, Kaiser LimNo Product/Research Disclosure Information.

To offer a practical demonstration of receiver operating characteristic (ROC) analyses, diagnostic efficiency statistics, and their application to clinical decision making using a popular parent checklist to assess for potential mood disorder. ⋯ This study illustrates a series of steps in defining a clinical problem, operationalizing it, selecting a valid study design, and using ROC analyses to generate statistics that support clinical decisions. The ROC framework offers important advantages for clinical interpretation. Appendices include sample scripts using SPSS and R to check assumptions and conduct ROC analyses.

ILD PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: Exposure to fungi is a risk factor for different respiratory diseases. Traditional exposure measurements such as viable counts are time consuming and expensive, and do not take into account the total fungal cell biomass. Analysis of the enzyme β-N-acetylhexosaminidase (NAHA) in airborne samples has been used as a measure of total fungal biomass. This presentation will review this technique and assess its usefulness by presenting data from the domestic fungal exposure of patients with asthma and sarcoidosis, for the latter also in relation to clinical parameters. ⋯ The following authors have nothing to disclose: Ragnar Rylander, Barbara Salobir, Marjeta TerceljNo Product/Research Disclosure Information.
