The insertion of a subdural drain (SDD) after burr-hole drainage of chronic subdural hematoma (cSDH) was shown to reduce recurrence rate and improve outcome at 6 months. However, studies analyzing the rate of drain misplacement and complications associated with drain misplacement are sparse. ⋯ The occurrence of SDD misplacement is unignorable, because it leads to iatrogenic drain-associated complications and seems to affect bleeding events and hospitalization time of patients undergoing burr-hole drainage of cSDH.

Observational Study
Admission neutrophil-lymphocyte ratio predicts rebleeding following aneurismal subarachnoid hemorrhage.
The relationship between neutrophil-lymphocyte ratio (NLR) and the occurrence of rebleeding in aneurysmal subarachnoid hemorrhage (aSAH) is poorly understood. Our study aimed to investigate the association between NLR on admission and rebleeding following aSAH. ⋯ Higher NLR predicts the occurrence of rebleeding and poor outcome, and NLR combined with Fisher grade significantly improves the prediction of rebleeding following aSAH.

Comparative Study
Comparison of intraoperative CT with postoperative MRI for determining DBS electrode coordinates.
Deep brain stimulation (DBS) is an effective therapy for a variety of refractory movement disorders. Accurate lead placement in the target nucleus is critical to ensure therapeutic effects and to minimize side effects, and intraoperative computed tomography (iCT) scan has been used to target and confirm lead position. The objective of this study is to compare the accuracy of determining the x, y, and z coordinates of final lead placement using iCT scan relative to postoperative magnetic resonance imaging (MRI). ⋯ Significant differences exist between iCT scan and postoperative MRI DBS y and z lead coordinates, but not with x coordinates. Based on this series, iCT scan is more accurate when confirming x coordinates, and less accurate for confirming y and z coordinates during DBS operations.
