Review Meta Analysis
A meta-analysis of resected metachronous second non-small cell lung cancer.
This meta-analysis was designed to determine the effect of surgical treatment on overall survival of patients treated surgically for a second non-small cell lung cancer (NSCLC) that occurred after resection of an initial NSCLC. PubMed and Scopus databases were queried. ⋯ Meta-analyses revealed pooled operative mortality of 7% for the second resection, pooled 5-year overall survival of 46% after resection of the second NSCLC, and 79% after resection of the first NSCLC. These results suggest that surgical resection can be considered for patients who have a second primary NSCLC after resection of an initial lung cancer.

Williams syndrome is an uncommon genetic disorder associated with supravalvular aortic stenosis (SVAS) in childhood. We reviewed outcomes of children with Williams syndrome who underwent repair of SVAS during a 30-year period at a single institution. ⋯ Surgical repair of SVAS in children Williams syndrome has excellent early results. However, significant late mortality and morbidity warrants close follow-up.

Pulmonary alveolar proteinosis (PAP) is characterized by accumulation of lipoproteinaceous material in the terminal airways. Whole lung lavage (WLL) remains the gold standard treatment but may be particularly challenging in cases of severe hypoxemia. We present a 3-step strategy that was used in a patient with PAP-associated refractory hypoxemia and that combined venovenous extracorporeal membrane oxygenation (vvECMO), double-lumen orotracheal intubation, and bilateral multisegmental sequential lavage (MSL). The procedure was well tolerated and permitted weaning from the ventilator.

We have developed a four-dimensional (4D) lung cancer model that forms perfusable tumor nodules. We determined if the model could be modified to mimic metastasis. ⋯ The 4D lung cancer model can isolate tumor cells in 3 phases of tumor progression. This 4D lung cancer model may mimic the biology of lung cancer metastasis and may be used to determine its mechanism and potential therapy in the future.

Comparative Study
Propensity adjusted analysis of open and endovascular thoracic aortic repair for chronic type B dissection: a twenty-year evaluation.
Optimal treatment of chronic type B aortic dissection (CBAD), whether open (open descending aortic repair, OAR) or endovascular (thoracic endovascular aortic repair, TEVAR), is controversial, suggesting a comparative analysis is warranted. ⋯ Intervention for CBAD can be performed with excellent results, either by an open or endovascular approach. The higher rate of treatment failure after TEVAR warrants modification of current device design or endovascular approach before broad application of this treatment strategy.
