The true incidence of occult N2 lymph node metastasis in patients with clinical N0 non-small cell lung cancer (NSCLC) remains controversial. Estimation of the probability of N2 lymph node metastasis can assist physicians when making diagnosis and treatment decisions. ⋯ Our prediction model estimated the pretest probability of N2 disease in computed tomography-defined N0 NSCLC and was more accurate than the existing models. Use of our model can be of assistance when making clinical decisions about invasive or expensive mediastinal staging procedures.

Constrictive pericarditis causes hepatic congestion, which results in congestive hepatopathy and finally leads to cardiac cirrhosis. However, in previous studies, risk stratification from the viewpoint of liver dysfunction was not performed in patients who underwent pericardiectomy for constrictive pericarditis. ⋯ It is meaningful to apply the Child-Pugh scoring system for the prediction of mortality after radical pericardiectomy in patients with constrictive pericarditis.
