Minimally invasive approaches for histological diagnosis of anterior mediastinal masses.
Anterior mediastinal masses include a wide variety of diseases from benign lesions to extremely malignant tumors. Management strategies are highly diverse and depend strongly on the histological diagnosis as well as the extent of the disease. We reported a prospective study comparing the usefulness of core needle biopsy and mini-mediastinotomy under local anesthesia for histological diagnosis in anterior mediastinal masses. ⋯ Core needle biopsy is effective in the diagnosis of pulmonary and pleural diseases. Yet its diagnostic yield in mediastinal mass is rather low. Superior to core needle biopsy, biopsy through a mini-mediastinotomy under local anesthesia is highly effective in the histological diagnosis of anterior mediastinal mass, and has a satisfactory diagnostic yield. The method is safe, minimally invasive, cost-effective, and useful in therapeutic decision making for anterior mediastinal masses.

Hilar cholangiocarcinoma: preoperative evaluation with a three dimensional volumetric interpolated breath-hold examination magnetic resonance imaging sequence.
Early detection and accurate staging are crucial for planning treatment and improving survival rate of hilar cholangiocarcinomas. This study investigated the diagnostic value of a three dimensional, spoiled gradient echo, T1-weighted magnetic resonance (MR) imaging sequence (3D volumetric interpolated breath-hold examination, 3D-VIBE) in the preoperative evaluation of hilar cholangiocarcinoma. ⋯ Gadolinium enhanced 3D-VIBE is better than 2D T1-weighted enhanced sequence in the preoperative assessment of the morphologicalal type, the intraductal infiltrating extent and the tumor resectability of hilar cholangiocarcinomas.

Mid-term effects of lung volume reduction surgery on pulmonary function in patients with chronic obstructive pulmonary disease.
Now lung volume reduction surgery (LVRS) has become one of the most effective methods for the management of some cases of severe chronic obstructive pulmonary disease (COPD). We evaluated the mid-term effects of LVRS on pulmonary function in patients with severe COPD. ⋯ LVRS may significantly improve pulmonary function in patients with severe COPD indicating for LVRS. Mid-term pulmonary function 3 years after surgery can be decreased to the level at 3 months after surgery. Three years after LVRS, lung volume and pulmonary ventilation function can be significantly improved, but the improvement in gas exchange function was not significant.

Comparative StudyDrug-eluting stent for the treatment of small coronary lesion: comparison between sirolimus- and paclitaxel-eluting stent.
Patients with small coronary lesions are at increased risk for repeat interventions after coronary angioplasty and stenting. The efficacy of drug-eluting stents (DES) has been demonstrated to improve the outcomes of these patients and is a focus of interest. Currently, two platforms of DES are available (sirolimus-eluting stent (SES) and paclitaxel-eluting stent (PES)). However, it has less been known that DES, SES vs PES, is superior for the treatment of small coronary lesions. ⋯ In this small sample-size, non-randomized study, the data indicated that implantation of SES for the treatment of patients with small coronary lesion showed more favorable results in respect of restenosis compared with PES implantation.
