Observational Study
Diagnostic Ability of a Dynamic Multidisciplinary Discussion in Interstitial Lung Diseases: A Retrospective Observational Study of 938 Cases.
The advice of a dynamic multidisciplinary discussion (MDD) is believed to be important in the diagnosis of interstitial lung diseases (ILDs). However, to what extent MDD diagnoses differ from the preliminary diagnoses before formal workup and MDD (preMDD diagnoses) is still insufficiently studied. ⋯ The MDD provided a definite diagnosis in 80.5% of presented cases, suggesting further investigations in almost all others. Given the high number of patients without preMDD diagnosis, the rate of change in preMDD diagnoses (41.9% of patients with a preMDD diagnosis) probably is an underestimation. The better prognostic discrimination among ILDs by using MDD indicates the added value of MDD in ILD.

Misdiagnosis of COPD is common. The goal of this study was to quantify the health services burden of undiagnosed and overdiagnosed COPD in a real-world, North American population. ⋯ Undiagnosed and overdiagnosed COPD contribute to significant health care burden. Given that misdiagnosed COPD was fivefold more common than correctly diagnosed COPD, these findings point to a substantial misdiagnosis-associated burden of disease that might be prevented, at least in part, with a correct diagnosis.

Case Reports
A 68-Year-Old Lung Transplant Recipient With Shortness of Breath, Weight Loss, and Abnormal Chest CT.
A 68-year-old man presented to our ED with shortness of breath, weakness, and a 25-lb unintentional weight loss. He had undergone bilateral lung transplantation (cytomegalovirus [CMV]: donor+, recipient+; Epstein-Barr virus: donor+; recipient+) for idiopathic pulmonary fibrosis (IPF) 18 months prior. His posttransplant course was fairly unremarkable until 1 month earlier, when he was admitted for breathlessness and weakness. ⋯ His cortisol level was undetectable; he was diagnosed with adrenal insufficiency and fludrocortisone was initiated. He was taking prednisone, tacrolimus, and everolimus for immunosuppression and valganciclovir, itraconazole, and trimethoprim-sulfamethoxazole for antimicrobial prophylaxis. His 25-lb weight loss occurred over the span of just one month.

Case Reports
A 47-Year-Old Man With Fever, Dry Cough, and a Lung Mass After Redo Lung Transplantation.
A 47-year-old man who was a redo double lung transplant recipient (cytomegalovirus [CMV] status: donor positive/recipient positive; Epstein-Barr virus status: donor positive/recipient positive) presented to the hospital with 1 week of generalized malaise, low-grade fevers, and dry cough. His redo lung transplantation was necessitated by bronchiolitis obliterans syndrome, and his previous lung transplantation 5 years earlier was for silicosis-related progressive massive fibrosis. He denied any difficulty breathing or chest pain. ⋯ He had a history of 1 earlier episode of CMV viremia that was treated with valganciclovir. His immunosuppressive regimen included tacrolimus, mycophenolate mofetil, and prednisone, and his infection prophylaxis included trimethoprim-sulfamethoxazole, itraconazole, and valganciclovir. Results of a chest radiograph 8 weeks earlier were normal.

A 68-year-old man with a history of chronic lymphocytic leukemia well controlled on ibrutinib, hypertension, obesity, and a remote history of smoking (10 pack-years) presented with increasing dyspnea on exertion and cough. He had previously finished two courses of oral antibiotics for his symptoms without significant improvement. On presentation, he had no fevers or sputum production.
