[First experience of stereotactic radiation therapy for vestibular schwannoma using CyberKnife].
Currently stereotactic radiosurgery has become the treatment of choice in small vestibular schwannomas. This paper discusses our first experience of application of CyberKnife system for stereotactic irradiation of these tumors. From April 2009 till June 2011 we treated 62 patients (35 female and 27 male) with vestibular schwannomas. ⋯ However we observed stable tendency: larger initial volume of the tumor and presence of trigeminal nerve dysfunction before treatment were poor prognostic factors for trigeminal neuropathy. Stereotactic irradiation using CyberKnife system is effective and sufficiently safe technique for management of vestibular schwannoma. The paper demonstrates high rates of tumor stabilization, hearing preservation and minimal incidence of complications associated with trigeminal or facial nerve.

[Microsurgical treatment of cerebral arteriovenous malformations in Burdenko Neurosurgical Institute (recent experience)].
Recently the number of AVM resections in Burdenko Neurosurgical Institute has been increased dramatically. Aim of this study was to assess the results of open surgery in our clinic in modern neurosurgical era. Consecutive series if 160 patients with AVM treated using microsurgical technique since 2009 till 2011 was analyzed. ⋯ Glasgow outcome scale score distribution was the following: V (good recovery)--70 (43.7%), IV (moderate disability)--71 (44.4%), III (severe disability)--16 (10%), II (vegetative state)--1 (0.6%) and I (death)--2 (1.3%). Microsurgery remains the primary option for radical treatment of cerebral AVMs. Careful selection of patients and planning of surgery are crucial for good outcomes.

[Simvastatin efficacy in vasospasm treatment in patients after aneurysm SAH].
Number of trials had previously demonstrated cerebroprotective effect of statin therapy in SAH patients. Aim of the current study was to assess effects of simvastatin on vasospasm in clinical practice. The study group comprised 35 patients admitted to Burdenko Neurosurgery Institute with aneurysmal SAH in 2007-2011. ⋯ Statin group showed significantly lower rates of vasospam progression--42.9% vs. 76.7% in control (chi2-test, p = 0.01). Our evidence corresponds with outcomes of international trials of statin application in SAH patients. As follows from our results and existing randomized and clinical trials data there is no strong evidence nowadays to recommend statin prescription in SAH patients.
