Nonexamination of lymph nodes is an extreme example of the variability of pathologic nodal staging of non-small cell lung cancer. We compared the prevalence, characteristics, and survival of patients without lymph nodes (pNX) to patients with documented pathologic N0 and pathologic N1 non-small cell lung cancer. ⋯ Patients with pNX resections are a high-risk subset, with survival approximating pathologic N1, not N0. They should have further attempts at retrieving lymph nodes for examination or be offered postoperative adjuvant chemotherapy. We predict that treatment modalities that fail to address lymph nodes are likely to yield inferior survival in comparison to surgery with proper lymph node examination. The proportion of pNX lung resections may be a sentinel quality indicator for lung cancer programs.

Comparative Study
Thoracoscopic Nuss procedure for young adults with pectus excavatum: excellent midterm results and patient satisfaction.
Chest wall remodeling by substernal placement of a Nuss bar is the treatment of choice for children with pectus excavatum; however, it has not yet gained widespread acceptance in adults. We demonstrate that thoracoscopic Nuss bar insertion in young adults is safe and leads to excellent results. ⋯ For young adults who wish to correct their pectus deformity, a thoracoscopic Nuss procedure is safe and results in a high rate of patient satisfaction, significant improvement in self-image, and excellent midterm cosmetic results.

Comparative Study
The Aristotle score predicts mortality after surgery of patent ductus arteriosus in preterm infants.
Outcomes after surgical ligation of patent ductus arteriosus (PDA) in preterm infants are often complicated by prematurity associated comorbidities. The Aristotle comprehensive complexity score (ACCS) has been proposed as a useful tool for complexity adjustment in the analysis of outcome after congenital heart surgery. The aims of this study were to define preoperative risk factors for mortality and to demonstrate the usefulness of ACCS to predict mortality after surgical ligation of PDA in the preterm. ⋯ The ACCS, especially for procedure-independent complexity factors, is a useful tool to predict mortality after ligation of PDA in preterm infants.
