Disseminated intravascular coagulation (DIC) is often associated with infection and a poor outcome. In this study, useful markers for predicting poor outcomes were examined. ⋯ The outcomes of septic patients primarily depend on the SOFA score and the resolution of DIC, which are related to organ failure.

Fibrosing mediastinitis is rare. One type of this disease is idiopathic fibrosing mediastinitis. It is necessary to rule out malignancy in order to accurately diagnose fibrosing mediastinitis. ⋯ Immediately after initiating chemotherapy for lymphoma, the patient's symptoms improved dramatically and the mediastinal lesion decreased in size. Although few similar cases have been reported, hidden malignancy may present as fibrosing mediastinitis. Therefore, physicians should consider the probability of malignancy in patients with fibrosing mediastinitis because treatments may vary accordingly.

Case Reports
Two cases of acute respiratory distress syndrome with high values of Chlamydophila pneumoniae-specific antibodies.
We herein report two cases of acute respiratory distress syndrome (ARDS) with high values of Chlamydophila pneumoniae-specific antibodies. In the first case (a 65-year-old man), high levels of anti-C. pneumoniae antibodies (IgG and IgA) were detected on admission, and the anti-C. pneumoniae IgA level rose by Day 30. The patient was successfully treated with quinolone and steroids. ⋯ The patient did not recover, despite receiving treatment with several antibiotics and anti-inflammatory agents. Neither of the patients displayed other pathogen-specific antigens or antibodies. Chlamydophila pneumonia is usually mild, although it can cause severe interstitial pneumonia and ARDS in reinfected patients and the elderly.

Case Reports
Methemoglobinemia induced by trimethoprim-sulfamethoxazole in a patient with systemic lupus erythematosus.
We herein report a case of methemoglobinemia induced by trimethoprim-sulfamethoxazole (TMP/SMX). A 41-year-old woman with systemic lupus erythematosus (SLE) received TMP/SMX for prophylaxis of pneumocystis pneumonia (PCP) on the 7th day of hospitalization. ⋯ We diagnosed the patient with methemoglobinemia induced by TMP/SMX. Methemoglobinemia should be considered in cases of sudden dyspnea following TMP/SMX administration.

Obtaining an accurate histopathological diagnosis is mandatory for the optimal treatment of patients who are suspected of having recurrent lung cancer. The purpose of this retrospective study was to investigate the usefulness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for the diagnosis of recurrent non-small cell lung cancer (NSCLC) among patients who undergo curative surgical resection. ⋯ Convex probe EBUS-TBNA is a sensitive method for diagnosing recurrent NSCLC in patients with lymph node and peribronchial lung parenchymal lesions. Therefore, EBUS-TBNA should be considered first for the cytopathological diagnosis of recurrent NSCLC.
