Can chronic neuropathic pain following thoracic surgery be predicted during the postoperative period?
Chronic pain following thoracic surgery is common and associated with neuropathic symptoms, however, the proportion of patients with neuropathic pain in the immediate postoperative period is unknown. We aimed to determine the proportion of patients who have neuropathic symptoms and signs immediately after, and at three months following thoracic surgery. The study was designed as a prospective observational cohort study. ⋯ Eight percent of patients had positive LANSS scores in the immediate postoperative period; 22% of patients had positive S-LANSS scores three months following surgery. There was a significant association between positive scores in the acute and chronic periods (relative risk (RR) 3.5, [95% confidence interval (CI) 1.7-7.2]). Identifying pain of predominantly neuropathic origin in the postoperative period with a simple pain score can help identify those at risk of developing chronic pain with these features following thoracic surgery.

Case ReportsSplenic tear causing a hemoperitoneum after cardiac surgery.
Hemoperitoneum after cardiac surgery is a very rare but life-threatening complication. We have only found a few cases described in the literature, in which the intra-abdominal hemorrhages were caused by liver bleeding, due to direct hepatic trauma or spontaneous hepatic rupture. We describe the first case of hemoperitoneum caused by a spontaneous rupture of the spleen.

Malignant pleural effusion in the presence of trapped lung. Five-year experience of PleurX tunnelled catheters.
Malignant pleural effusions in the presence of trapped lung remain notoriously difficult to treat. Various methods exist ranging from minimally invasive procedures including repeated needle thoracocentesis to the need for a formal surgical procedure such as placement of a pleuroperitoneal shunt and even thoracotomy and decortication. Controversy exists as to what is the optimum treatment for this condition. ⋯ No patient required catheter removal for resolution of discomfort. Our findings support the use of PleurX catheters for palliative patients with malignant pleural effusions in the presence of trapped lung. The catheters are not only easy to insert and discrete but they can be managed effectively by patients and community nurse practitioners and prevent repeated admissions to hospital in palliative patients with compromised life expectancy.

ReviewIn patients with first-episode primary spontaneous pneumothorax is video-assisted thoracoscopic surgery superior to tube thoracostomy alone in terms of time to resolution of pneumothorax and incidence of recurrence?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed whether video-assisted thoracoscopic surgery (VATS) was justifiable for first-episode primary spontaneous pneumothorax (PSP). Altogether 183 papers were found using the reported search, of which nine represented the best evidence to answer the clinical question. ⋯ Instead, secondary treatment is recommended. Lastly, two articles also examined the rate of recurrence of VATS compared to open thoracotomy (OT). The range was from 0 to 7.7% for OT vs. 10.3 to 13% for VATS, a non-statistical difference.

ReviewDoes intermittent cross-clamp fibrillation provide equivalent myocardial protection compared to cardioplegia in patients undergoing bypass graft revascularisation?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: does intermittent cross-clamp fibrillation provide equivalent myocardial protection compared to cardioplegia in patients undergoing bypass graft revascularisation? Altogether, 58 papers were found using the reported search, of which 13 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. ⋯ The ischaemic duration associated with intermittent cross-clamp fibrillation is invariably shorter than that associated with cardioplegic arrest, and this may be one explanation for the comparable outcomes. There may also be an element of preconditioning protection during the intermittent cross-clamp fibrillation method, as has been shown experimentally. During elective CABG in patients with no clinical evidence of aortic or cerebro-vascular disease, the incidence of peri-operative microemboli (ME) and postoperative neuropsychological disturbances are shown to be comparable with both techniques of myocardial preservation.
