Background: Since the late 1980s, the policy of the Japanese government regarding physician manpower has been to decrease the number of medical students. However, the shortage of doctors in Japan has become a social problem in recent years. The aim of this study was to compare the numbers of physicians in Japan between 1996 and 2006 and the trends in distribution of physicians.

Background: Accurate cost estimate and a profit and loss analysis are necessary for health care practice. We performed an actual financial analysis for an intensive care unit (ICU) of a university hospital in Japan, and tried to discuss the health care policy and resource allocation decisions that have an impact on critical intensive care.

Among the clinical stage IA NSCLC patients in whom all four predictors were identified, one third of the patients showed mediastinal nodal metastasis, and thus, those patients should be a target for mediastinal node assessment by invasive modalities, such as mediastinoscopy or endobronchial ultrasound-guided transbronchial needle aspiration.

Segmentectomy should be the surgical procedure of first choice in patients with clinical stage IA NSCLC who are being considered for sublobar resection. Patients having tumors presenting with no suspicious of pleural involvement would be suitable candidates for sublobar resection.
