Purpose: Although, endobronchial ultrasonography with a guide sheath is becoming a common procedure for the diagnosis of peripheral pulmonary lesions, there remain to be some inaccuracies in cases wherein the probe is located outside the lesion. We tested whether adding transbronchial needle aspiration through a guide sheath to the conventional technique increases efficacy for diagnosing peripheral pulmonary lesions. Methods: We performed transbronchial needle aspiration through a guide sheath for 37 subjects with peripheral pulmonary lesions between September 2012 and April 2013. The devices used were as follows (all Olympus Ltd., Tokyo, Japan): 1T-260 or LF-TP bronchoscope, K203 guide sheath kit and NA-1C-1 needle apparatus, customized by cutting the guide sheath 30 mm from the proximal end to fit well with the needle. Results: The endobronchial ultrasound probe was located within the lesion in 21 cases (56.8%) and outside in 16 cases (43.2%). Overall accuracy was 86.5 percent; 90.5% in "within" cases compared to 81.3% in "outside" cases with no significant difference (P = 0.42). Pneumothorax occurred in 2 cases and pneumonia in 1 case. Conclusion: Transbronchial needle aspiration through a guide sheath is an effective and safe diagnostic procedure for peripheral pulmonary lesions, especially when the guide sheath is outside the lesion.

Rapidly progressive interstitial lung disease (ILD) is associated with dermatomyositis (DM) and has a high mortality rate even with immunosuppressive agents. For such cases, there is no evidence on the combined effect of direct hemoperfusion with a Polymyxin B immobilized fiber column and intravenous immunoglobulin. We herein report a case of 61-year-old woman who presented with respiratory failure. She showed ILD associated with DM which did not improve with immunosuppressive agents, but was improved with the addition of both direct hemoperfusion with a Polymyxin B immobilized fiber column and intravenous immunoglobulin.

We herein report the case of an 84-year-old who developed pneumonia after drowning in a rice field. Besides Aspergillus fumigatus, many pathogens previously not reported in drowning-associated pneumonia (such as Pseudomonas fluorescens, Pseudomonas putida, Nocardia niigatensis, and Cunninghamella sp.) were isolated from his sputum. He received sulbactam/ampicillin, trimethoprim/sulfamethoxazole, voriconazole, levofloxacin and liposomal amphotericin B, but died due to respiratory failure. Because the patient had drowned in a contaminated stagnant rice field and had multiple lung cavities, zygomycosis was suspected. This report provides invaluable information for the consideration of zygomycosis after an individual drowning in a rice field, even in an immunocompetent patient.
