Case Reports
A 43-year-old man with antisynthetase syndrome presenting with acute worsening of dyspnea.
A 43-year-old man with antisynthetase syndrome was seen in our pulmonary clinic for worsening dyspnea. He was recently diagnosed with antisynthetase syndrome because he had nonspecific interstitial pneumonitis on a surgical lung biopsy and polymyositis associated with anti-Jo-1 and anti-SSA-52 autoantibodies. ⋯ He had been taking prednisone 40 mg daily 2 months prior, which had been recently weaned to 20 mg daily. He had also been on mycophenolate mofetil but had recently discontinued it on his own.

As seen in this CME online activity (available at http://journal.cme.chestnet.org/home-niv-copd), COPD is a common and debilitating disease and is currently the third leading cause of death in the United States. The role of noninvasive ventilation (NIV) in the management of severe, hypercapnic COPD has been controversial. However, it was concluded that current data would support the following recommendations. ⋯ The proper use of NIV in appropriately chosen patients with COPD can improve quality of life and increase survival. Ongoing studies are assessing if the frequency of future hospitalizations can be reduced with NIV. Thus, NIV should be strongly considered in any patients with COPD meeting the criteria described here.

Comparative Study Observational Study
Comparison of a self-inflating bulb syringe and a colorimetric carbon dioxide indicator with capnography and radiography to detect the misdirection of naso-orogastric tubes into the airway of critically ill adult patients.
The objective of this study was to develop a mechanism of discovering misdirection into the airway of naso/orogastric (NG) tubes before they reach their full depth of placement in adults. ⋯ The SIBS and the colorimetric CO2 detector are very good at detecting NG tube malpositioning into the airway, although the colorimetric device is slightly more sensitive and specific. Neither method adds substantial time or difficulty to the insertion process. The colorimetric device is substantially more expensive. The decision as to which method to use may be based on local institutional factors, such as expense.
