We report a complication of the novel H1N1 influenza A viral infection not yet described during this 2007-2009 pandemic. Pulmonary hemorrhage is a known complication of influenza pneumonia, including well documented reports from previous pandemics. A 57-year-old African American female presented with fevers, progressive shortness of breath, and cough. After being admitted with an initial diagnosis of myocardial infarction, hemoptysis developed. Nasopharyngeal swabs rapid testing was negative for influenza A and B antigen, but a polymerase chain reaction test for influenza A type H1N1 was positive. A fiberoptic bronchoscopy for ongoing hemoptysis demonstrated diffuse erythema and bleeding, and bronchoalveolar lavage was consistent with alveolar hemorrhage. Progressive hypoxemic respiratory failure ensued, eventually leading to her demise. Our case highlights one of the more feared complications that may have been more common in prior outbreaks, such as the 1918 "Spanish Flu." Autopsy studies from the 1918 influenza pandemic found severe tracheobronchitis (oftentimes hemorrhagic), septal edema, necrotizing bronchiolitis, alveolitis, and extensive hemorrhage, as opposed to the more benign laryngitis and tracheobronchitis that is commonplace in other influenza infections. Similar pathology appearances, including pulmonary hemorrhage, have also been described in H5N1 outbreaks in China and Thailand. It is crucial for pandemic preparedness planning that additional careful and complete autopsy study of this present pandemic influenza infection be performed and reported to answer questions regarding the natural history, pathology, and pathogenesis of this novel H1N1 influenza.

A 34-year-old man with uncontrolled hypertension suffered a ventricular fibrillation cardiac arrest from an obstructive left anterior descending artery occlusion. He was defibrillated more than 10 times before achieving return of spontaneous circulation. He was comatose after his arrest and was treated with therapeutic hypothermia, and a bare metal stent was placed in his obstructed coronary artery with restoration of excellent postobstruction blood flow. His postarrest course was complicated by cardiogenic shock; prolonged ventilator-dependent respiratory failure requiring tracheostomy; tracheobronchitis, with cultures positive for methicillin-resistant Staphylococcus aureus (MRSA); and an extended period of agitation and delirium. Thirty-four days after his arrest, his mental status started to improve rapidly. His delirium resolved, he became oriented and lucid, and he was able to be discharged to a rehabilitation facility on hospital day 41, with an excellent prognosis and close follow-up in primary care, cardiology, tracheostomy, and coumadin clinics. He returned to the emergency department 65 days later with the complaint of intermittent chest pain of 4 days' duration. Upon physical examination he was found to have Beau's lines on his fingernails. He was admitted to the hospital for a rule-out myocardial infarction workup, which was uneventful. He was discharged to home in good condition 2 days later.
