ReviewDoes the use of extended criteria donors influence early and long-term results of lung transplantation?
A best evidence topic was constructed according to a structured protocol. The question addressed was whether the presence of extended criteria donors influences the early and long-term results in patients referred for lung transplantation. Of the 30 papers found using a report search, 14 presented the best evidence to answer the clinical question. ⋯ Finally, the importance of avoiding the donation of the lung from an MD to a high-risk recipient emerged, whereas the association with single or bilateral transplants remains more controversial. Hence, current evidence suggests that there are no contraindications-given the absence of negative impact on survival-for the use of MDs for the transplant of a proposed standard receiver. However, given the low level of evidence of published studies, caution is necessary in order to avoid organ shortage, despite these encouraging results.

Case ReportsFolding mitral valvuloplasty without posterior leaflet resection for calcified mitral annulus.
Mitral valve annular calcification has long been a challenge in repairing posterior mitral valve prolapse. Folding valvuloplasty of the posterior leaflet without resection provides a means of circumventing common procedural complications. This report demonstrates the success of folding valvuloplasty without resection in the treatment of mitral valve prolapse and severe annular calcification.

Surgical treatment of stage IV non-small cell lung cancer.
Most stage IV non-small-cell lung cancer (NSCLC) patients are not amenable to curative treatment. The purpose of this study was to analyse our initial experience with an aggressive surgical strategy for stage IV NSCLC, and to define which patients can benefit from this treatment. Forty-six stage IV NSCLC patients who underwent surgical resection of both primary lung cancer and metastatic sites from April 1989 to December 2010 were included in this study. ⋯ Patients with the pN2 status had a significantly worse survival than patients with a pN0 or pN1 status (8.6 versus 33.1%, P = 0.0497). According to a multivariate Cox proportional hazards analysis, no independent predictor of survival was identified. The results of our study suggest that surgical treatment can extend the survival in stage IV NSCLC patients if the patients can tolerate surgery.

Pulmonary metastasectomy: a multivariate analysis of 440 patients undergoing complete resection.
Surgical resection is currently a standard approach for isolated lung metastases from different primary tumours. The aim of the present analysis is to evaluate the outcome of patients submitted to complete resection of pulmonary metastases and to determine prognostic factors for long-term survival. A group of 440 consecutive patients previously diagnosed with primary malignant solid tumours and submitted to complete surgical resection of lung nodules with suspected or diagnosed metastatic lesion were retrospectively reviewed. ⋯ Multivariate analysis: number of malignant nodules resected (P = 0.01), size of the largest nodule resected (P = 0.001), DFI >36 months (P < 0.001) and histology of the primary tumour (P = 0.017) had significant impact on survival. The benefit of such an aggressive surgical approach is only limited to selected subgroups of patients. The decision to consider a patient for resection of metastastic disease should include factors beyond the feasibility of complete removal.

ReviewDoes adding ketamine to morphine patient-controlled analgesia safely improve post-thoracotomy pain?
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'is the addition of ketamine to morphine patient-controlled analgesia (PCA) following thoracic surgery superior to morphine alone'. Altogether 201 papers were found using the reported search, of which nine represented the best evidence to answer the clinical question. ⋯ Both papers reporting respiratory outcomes found improved oxygen saturations and PaCO(2) levels in PCA-MK patients following thoracic surgery. We conclude that adding low-dose ketamine to morphine PCA is safe and post-thoracotomy may provide better pain control than PCA with morphine alone (PCA-MO), with reduced morphine consumption and possible improvement in respiratory function. These studies thus support the routine use of PCA-MK instead of PCA-MO to improve post-thoracotomy pain control.
