One patient in our hospital was diagnosed and the literatures on the subject were reviewed. The patient presented with high fever and dyspnea. Arterial gas analysis indicated type 1 respiratory failure. Chest X ray photographs showed bilateral infiltrations and bilatera encapsulated pleural effusions. Viral separation and culture of pharyngeal swab indicated H3N2 subtype of human influenza virus. Blood, sputum and bronchoalveolar lavage fluid (BALF) cultures showed Staphylococcus aureus. Pleural effusion was complex parapneumonic pleural effusion. After the administration of anti-virus, anti-staphylococcal antibiotics and pleural cavity drainage, the patient was cured. The infection of staphylococcus aureus is a typical characteristic of influenza pneumonia, and anti-staphylococcal antibiotic therapy (with MRSA activity in MRSA endemic regions) should be initiated in hospitalized cases of influenza pneumonia. If complex parapneumonic pleural effusion or empyema complicated, we should perform pleural cavity drainage in time. The oral neuraminidase inhibitor (oseltamivir) could significantly improve prognosis.展开更多

Retrospective analyses of the clinical features of LG and pathology features by open lung bio-psies were conducted. The patient was a 42-year-old female with irregular fever,and her chest X-ray and computed tomography showed nodules with cavity and pleural effusion. Open lung biopsy proved LG. LG is seldom seen in clinic. Open lung biopsy is very important for pathology diagnosis. Early diagnosis and treatment are the key to improving survival in these patients. The therapeutic effect is good.展开更多
