Effect of preoperative hospital stay on surgical site infection in Chinese cranial neurosurgery.

Objective: Surgical site infection(SSI)after neurosurgical procedure can be devastating. Delayed hospital stay has been identified as a potentially modifiable driver of SSI in general surgery patients. However, the relationship between preoperative length of stay and SSI has not been quantified previously in neurosurgery.

[CT features and anatomic distribution of pleural dissemination in lung cancer].

Background: To study the CT appearance of lung cancer combined with pleural dissemination and its anatomic characteristics.

Methods: CT findings of 32 cases of lung cancer with pleural dissemination proved by surgery and pathology were analyzed.

Results: The main CT manifestations were pleural effusion (24 cases), visceral pleural dissemination with nodules (10 cases), parietal pleural dissemination with nodules (16 cases), and pleural thickening (31 cases).
