The progression of scoliosis after fusion surgery is a poor prognostic factor of long-term outcomes in patients with degenerative lumbar stenosis (DLS). In this study we aimed to investigate changes in coronal alignment and identify risk factors related to progression of scoliosis after fusion. ⋯ The global magnitude of progression of the Cobb angle after short-segment lumbar fusion surgery in patients with DLS is similar to the natural curve progression of adult degenerative scoliosis.

Previous studies have demonstrated that increasing age is associated with decreased rates of operative management and gross total resection in patients with vestibular schwannomas. ⋯ In patients undergoing surgery for benign cranial nerve neoplasms, increasing age is associated with increased mortality, stroke, coma, and ventilator weaning failure. Composite complication rates are significantly greater in patients ≥70 years, with a near 80-fold increased risk of complications.

Case Reports
Recurrent herpes simplex virus encephalitis after a neurological surgery: A case report.
The herpes simplex virus (HSV) is the most common cause of sporadic encephalitis worldwide. Even with proper treatment, this infection is associated with a mortality rate of 19%-30% and with potential neurologic sequelae. Recurrences of encephalitis are rare and limited to a few cases in the literature. Although the mechanism of reactivation has not yet been clarified, in our patient, the surgery might have acted as a precipitating factor. ⋯ HSV encephalitis is a rare but serious complication that should be suspected in cases of unexplained postoperative fever with altered consciousness, especially in patients with histories of encephalitic states.

To determine the safety and efficacy of endovascular treatment with the Solitaire device for acute basilar artery occlusion (ABAO) and identify factors affecting clinical outcomes. ⋯ Endovascular treatment with the Solitaire device yielded high recanalization rates in ABAO patients and favorable clinical outcomes in approximately one third of patients. Intracranial stenosis was the main cause of occlusion. Angioplasty was commonly performed during mechanical thrombectomy to improve recanalization and prognosis. Early recanalization and better prethrombectomy status predicted better outcomes.

Although most neurovascular centers currently have a coil first policy, the percentage of coiled versus clipped aneurysms, as well as treatment outcomes, varies strongly between these centers. This study evaluates the impact of an increase in clipping caseload on treatment outcome in a large single-center series. ⋯ The improvement of the surgical outcome after increasing the clipping caseload underlines the importance of sufficient surgical volume for maintenance of competitive treatment results.
