Usefulness of endobronchial ultrasound-guided transbronchial needle aspiration for diagnosis of sarcoidosis.
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an accurate and minimally invasive technique used routinely for investigation of mediastinal and hilar lymphadenopathy. However, few studies have addressed its role in comparison to the traditional diagnostic approaches of transbronchial lung biopsy (TBLB), endobronchial biopsy (EBB), and bronchoalveolar lavage (BAL) in the diagnosis of sarcoidosis. We evaluated the usefulness of EBUS-TBNA in the diagnosis of sarcoidosis compared to TBLB, EBB, and BAL. ⋯ EBUS-TBNA was the most sensitive method for diagnosing stage I and II sarcoidosis compared with conventional bronchoscopic procedures. EBUS-TBNA should be considered first for the histopathologic diagnosis of stage I and II sarcoidosis.

Perioperative nutritional status changes in gastrointestinal cancer patients.
The presence of gastrointestinal (GI) cancer and its treatment might aggravate patient nutritional status. Malnutrition is one of the major factors affecting the postoperative course. We evaluated changes in perioperative nutritional status and risk factors of postoperative severe malnutrition in the GI cancer patients. ⋯ The prevalence of severe malnutrition among GI cancer patients in this study increased from 2.3% preoperatively to 26.3% after an operation. Old age, preoperative weight loss, gastric cancer, and open surgery were shown to be risk factors of postoperative severe malnutrition. In patients at high risk of postoperative severe malnutrition, adequate nutritional support should be considered.

Easy identification of mechanical axis during total knee arthroplasty.
We devised an intraoperatively identifiable mechanical axis (IIMA) as a reference of alignment in total knee arthroplasty (TKA). ⋯ This study showed that IIMA could be of considerable value as a new guider of alignment that is easily accessible and highly effective during total knee arthroplasty.
