The goal of this study was to provide epidemiological and clinical data on the management of cavernomas of the basal ganglia and brainstem from a long-term series at one institution. ⋯ Over the long term, outcomes were worse following conservative treatment or shunt insertion surgery than after microsurgery of symptomatic cavernomas. Incidental cavernomas carried a low risk of neurological deterioration. Surgery should follow generally accepted indications, but only with the confidence that total removal can be safely achieved. Surgery that is performed within 10 to 30 days following ictus may be preferable to delayed surgery.

One-stage three-dimensional correction and fusion: a multilevel posterior lumbar interbody fusion procedure for degenerative lumbar kyphoscoliosis. Technical note.
Surgery for degenerative lumbar kyphoscoliosis (DLKS) is very challenging because the curve has become rigid due to circumferential osteoarthritic changes. Therefore, a standard procedure involving correction and fusion after decompression of the nerves has not yet been established. The authors have been searching for an effective procedure that provides adequate decompression and three-dimensional (3D) correction for symptomatic DLKS. ⋯ They analyze the results obtained in the first 23 cases and discuss the advantages and disadvantages of the procedure. The correction effect was excellent, and compared with other instrumentation-assisted procedures, this surgery is not remarkably invasive. Although the procedure is limited in achieving normal sagittal alignment and the acceleration rate of adjacent-disc degeneration remains relatively high, it is an option for the rigid deformity characterized by DLKS.

Volumetric quantification of cement leakage following percutaneous vertebroplasty in metastatic and osteoporotic vertebrae.
The goal of this study was to quantify volumetrically cement fill and leakage in patients with osteoporotic and metastatic vertebral lesions undergoing percutaneous vertebroplasty and to establish whether these factors have any clinical significance at follow up. ⋯ Although there was no correlation between cement fill or cement leakage and pain relief, there exists a risk of serious complications due to cement leakage.

Comparative StudyReduction in the number of repeated operations for the treatment of subacute and chronic subdural hematomas by placement of subdural drains.
The aim of this study was to determine the influence of closed-system subdural drainage on repeated operation rates after burr hole evacuation of subacute and chronic subdural hematomas (SDHs). ⋯ Patients have lower rates of repeated surgeries if subdural drains are placed following evacuation of an SDH via a burr hole. To reach high clinical significance, 12 patients must undergo this simple intervention. If technically feasible, subdural drains should be inserted regardless of any occurrence of brain expansion during surgery.

Clinical TrialThoracoscopic limited T-3 sympathicotomy for primary hyperhidrosis: prevention for compensatory hyperhidrosis.
Compensatory hyperhidrosis is a major and troublesome complication of thoracoscopic sympathectomy for primary hyperhidrosis. The incidence of compensatory hyperhidrosis has been reported to be as high as 50 to 97% in the patients who underwent sympathetic ganglia resection. In this study the authors evaluate the role of thoracoscopic T-3 sympathicotomy for primary hyperhidrosis and the prevention of compensatory hyperhidrosis. ⋯ Thoracoscopic limited T-3 sympathicotomy is an effective method to treat primary hyperhidrosis, its rate of compensatory hyperhidrosis is low, and its rate of long-term patient satisfaction is high.
