Rare Disease Case Report PostersSESSION TYPE: Case Report PosterPRESENTED ON: Sunday, March 23, 2014 at 01:15 PM - 02:15 PMINTRODUCTION: The differential diagnosis of lung nodules is vast. A history of smoking often leads the clinician to common entities such as malignancy, however less likely scenarios should be considered. ⋯ The clinician is often faced with a broad differential diagnosis for lung nodules. Less common entities should be given consideration, such as primary pulmonary nodular amyloidosis.Reference #1: Pinney J., and Hawkins B. Amyloidosis.

Critical Care Case Report PostersSESSION TYPE: Case Report PosterPRESENTED ON: Sunday, March 23, 2014 at 01:15 PM - 02:15 PMINTRODUCTION: Diffuse alveolar hemorrhage (DAH) is associated with negative pressure pulmonary edema secondary to acute upper airway obstruction. There have been no associations with the upper airway obstruction of obstructive sleep apnea. Negative intrathoracic pressure leads to an increase in pulmonary vascular volume and pulmonary capillary transmural pressure, creating a risk of disruption of the alveolar-capillary membrane. We present a case of DAH in a patient on anticoagulation with positive anti-cardiolipin antibody and low level anti-dsDNA triggered by severe obstructive sleep apnea. ⋯ The following authors have nothing to disclose: Sadaf Mir, Silviana Marineci, Mary O'SullivanNo Product/Research Disclosure Information.

Cardiovascular Case Report Posters ISESSION TYPE: Case Report PosterPRESENTED ON: Sunday, March 23, 2014 at 01:15 PM - 02:15 PMINTRODUCTION: For regional anesthesia, lidocaine bupivacaine combination is popular due to the advantage of quick onset action of lidocaine and longer duration of action of bupivacaine. Although a safe procedure, toxicity from local anesthetics can result from local absorption and/or inadvertent direct IV injection. Direct cardiac toxic effects of local anesthetics involve arrhythmias and/or direct myocardial injury/ suppression. A recent study showed that bupivacaine induce mitochondrial swelling in myocarium with resultant negative inotropic effects. Bupivacaine in high doses or unintentional intravascular injection may lead to high plasma levels and related depression of the myocardium, heart block, hypotension, bradycardia, ventricular arrhythmias, and cardiac arrest. There is very limited echocardiographic and ventriculographic evidence of bupivacaine induced cardiac dysfunction. ⋯ This case describes inverted takotsubo cardiomyopathy as a mechanism for bupivacaine induced cardiac suppression and demonstrates the need for increased awareness of the rare but serious cardiotoxic effects of bupivacaine when used for nerve blocks.Reference #1: Coyle DE et el Anesth Analg. 1994 Aug; 79(2):335-339DISCLOSURE: The following authors have nothing to disclose: Martinus Dyrud, Rakesh Gupta, Rumi KhanNo Product/Research Disclosure Information.

ILD PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: Thin-section computed tomography (CT) is better than normal chest radiograph in the detection of pulmonary lesion including smoke inhalation injury which is often non-specific on chest X-ray. Unfortunately, specific changes and findings in CT have not yet been described. The aim of this study is to identify and describe the most useful CT features in inhalation injury. ⋯ The following authors have nothing to disclose: In-Gyu Hyun, Cheol-Hong KimNo Product/Research Disclosure Information.

Tobacco Cessation and PreventionSESSION TYPE: Slide PresentationsPRESENTED ON: Saturday, March 22, 2014 at 12:15 PM - 01:15 PMPURPOSE: A number of non-pharmacological approaches to smoking cessation have been developed with varying degree of success. Intensive anti-smoking counselling remains to be evaluated in countries with limited budget for nicotine replacement therapy; hence this study aimed to define the role of intensive antismoking counselling in taking patients off tobacco in a low-income country. ⋯ The following authors have nothing to disclose: Maha GhanemNo Product/Research Disclosure Information.
