ILD Case Report Posters IISESSION TYPE: Case Report PosterPRESENTED ON: Sunday, March 23, 2014 at 01:15 PM - 02:15 PMINTRODUCTION: Non Specific Interstitial Pneumonia (NSIP) is a type of diffuse parenchymal lung disease with distinct clinico-pathologic features. It typically presents with progressive dyspnea and cough that develop sub-acutely. There are few reports of patients presenting with an acute exacerbation (AE) of NSIP at the time of initial diagnosis. ⋯ It has been well described that patients with Idiopathic Pulmonary Fibrosis may experience AE's and recently AE's have been described among patients with NSIP.1CONCLUSIONS: We believe our case represents an AE as the initial presentation of NSIP, which to our knowledge has not been previously described in the absence of prior imaging consistent with possible NSIP. Additionally our patient's accelerated clinical and radiographic improvement is unique.Reference #1: Park N, Kim S, et al. Acute Exacerbation of Interstitial Pneumonia Other Than IPF.

Comparative Study
Radiation risks in lung cancer screening programs: a comparison with nuclear industry workers and atomic bomb survivors.
The National Lung Cancer Screening Trial (NLST) demonstrated that screening with low-dose CT (LDCT) scan reduced lung cancer and overall mortality by 20% and 7%, respectively. The LDCT scanning involves an approximate 2-mSv dose, whereas full-chest CT scanning, the major diagnostic study used to follow up nodules, may involve a dose of 8 mSv. Radiation associated with CT scanning and other diagnostic studies to follow up nodules may present an independent risk of lung cancer. ⋯ This assessment suggests that long-term (20-30 years) LDCT screening programs are associated with nontrivial cumulative radiation doses. Current lung cancer screening protocols, if conducted over 20- to 30-year periods, can independently increase the risk of lung cancer beyond cigarette smoking as a result of cumulative radiation exposure. Radiation exposures from LDCT screening and follow-up diagnostic procedures exceed lifetime radiation exposures among nuclear power workers and atomic bomb survivors.

TransplantationSESSION TYPE: Slide PresentationsPRESENTED ON: Sunday, March 23, 2014 at 12:15 PM - 01:15 PMPURPOSE: Cor pulmonale can complicate end-stage lung disease in chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF), and cystic fibrosis (CF). Although the prevalence of pulmonary hypertension (PH) has been described in CF patients, these studies often drew small sample sizes from single centers. We aimed to describe the independent association between CF and PH compared to COPD and IPF. ⋯ The following authors have nothing to disclose: Nona Mei, Alex BalekianNo Product/Research Disclosure Information.

Pleural Disease/Pneumothorax PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: A recent series of case reports in children links Primary Spontaneous Pneumothorax (PSP) to alpha-1-antitrypsin (AAT) deficiency. However, epidemiological evidence of this link is lacking. We investigated our series of PSP to see if they have AAT deficiency. ⋯ The following authors have nothing to disclose: Tiong TheNo Product/Research Disclosure Information.

Multiple questionnaires have been used to predict the diagnosis of OSA. Such models typically have multiple questions requiring cumulative scoring for interpretation. We wanted to determine whether a simple two-part questionnaire has predictive value in the pretest clinical evaluation for OSA. ⋯ Among patients referred to a sleep disorders clinic, a positive response to being elbowed/poked for apneic spells significantly improves the pretest prediction of OSA.
