(1) Lung reexpansion provoked severe oxidative stress. (2) The degree of the amount of generated oxygen free radicals was associated to the duration of OLV. (3) Patients with lung cancer had a higher production of oxygen free radicals than normal population. (4)Tumor resection removes a large oxidative burden from the organism. (5) Mechanical ventilation and surgical trauma are weak free radical generators. (6) Manipulated lung tissue is also a source of oxygen free radicals, not only intraoperatively but also for several hours later.

Fibrinolytic agents are a useful adjunct in the management of complicated parapneumonic effusions. Intrapleural fibrinolytics, if used early in the fibrinopurulent stage of a parapneumonic effusion, decrease the rate of surgical interventions (VATS or open decortcation) and the length of hospital stay with minor associated morbidity.

A safe algorithm is recommended: eCXR for every patient who suffered blunt thoracic injury with at least one rib fracture detected and is treated as an outpatient or in case his/her compliance with the reevaluation schedule will be suboptimal. Close follow-up is also suggested since these entities do exist, cannot be ignored and their treatment is early evacuation of the pleura cavity.

Protracted (>1h) OLV should be considered a potential cause for cardiovascular complications through the generation of severe oxidative stress due to lung reexpansion.

(1) MLD was found to be more reliable for pN2/S detection than MLS. (2) The presence of pN2/S proved to be a less aggressive form of lymphatic spread that should be taken into account in the future. (3) Strong correlation between right lower lobe tumors and pN2/S was demonstrated. (4) Different routes of cancer lymphatic spread between pN2/S and pN2/O are suggested.
