Schoen K, et al. - Researchers reviewed patients with a confirmed diagnosis of H1N1 influenza A virus for the correlation between clinical and imaging findings with a worse clinical outcome. They assessed 160 (50%) patients (mean age: 43 ± 19 years); of these, 80 were men. The most commonly reported symptoms were: flu-like symptoms 141/160 (88%), dyspnea (25/160, 17%), and thoracic pain (7/160, 5%). Worse clinical outcomes were observed in correlation to the following variables: the presence of diabetes mellitus, hypertension, dyspnea, thoracic pain, abnormal chest radiography or computed tomography (CT) regardless of the type of finding, CT with consolidation or ground-glass opacity. These findings suggest the utility of readily accessible clinical and imaging features on admission in the evaluation of patients with H1N1 infection.
