To reveal the incidence and clinical significance of mediastinal nodal metastases without N1-station nodal metastases ('skip-N2 metastases') in non-small cell lung cancer (NSCLC). ⋯ N1 nodal status is not a useful predictor of N2 nodal status in NSCLC, because skip-N2 metastases were documented in 18% patients showing no N1-nodal involvement. However, N1 node-guided dissection might be performed in patients with adenocarcinoma showing lower PI, because the incidence of skip-N2 metastases was extremely low.

Role of endotracheal stenting in tracheal reconstruction surgery-retrospective analysis.
To review a single institution experience with tracheal stenosis treatment and to define a role of endotracheal stenting in tracheal reconstruction surgery. ⋯ Tracheal stenosis is a serious, life-threatening disease with increasing incidence. In our study, the best results were achieved by segmental tracheal resection. However, the endotracheal stenting is the method of choice, when the segmental resection cannot be performed. The management of tracheal stenosis reconstruction by our own modification of Montgomery T-tube is being presented.

Multicenter StudyRoss and Ross-Konno procedure in children and adolescents: mid-term results.
The aim of the study was to analyze mid-term results of aortic root replacement with pulmonary autograft in children and adolescents in two centers. ⋯ Our 7 years experience with the Ross and Ross-Konno operation has shown excellent mid-term results, with mortality rate approaching zero in both simple and complex left heart lesions, even in the neonates and infants. It is a procedure of choice in children with severe anomaly of the aortic valve and/or left ventricular outflow tract obstruction. The main concern is dilatation of the neo-aortic root leading to progression of AR, especially in the settings of geometric mismatch of aortic and pulmonary roots and bicuspid, regurgitant aortic valve. The risk of autograft failure in these specific subsets of patients remains to be determined.

Randomized Controlled Trial Clinical TrialChronic stable ischaemia protects against myocyte damage during beating heart coronary surgery.
Many patients with coronary artery disease demonstrate chronic resting ischaemic myocardial dysfunction. We have investigated whether this ischaemia influences the myocardial damage caused by the period of coronary occlusion involved in beating heart surgery. ⋯ In patients with chronic coronary artery disease, stable preoperative ischaemia may thus represent a naturally occurring form of myocardial protection, whose presence reduces Troponin T release after beating heart surgery. This protection is different in nature from classical ischaemic preconditioning.
