[Possibilities of dynamic phase contrast MRI of cerebrospinal fluid for performing a tap test in a patient with idiopathic normotensive hydrocephalus].

Idiopathic normotensive hydrocephalus (iNH) is a widespread disease in elderly patients. The effectiveness of iNG treatment and the subsequent quality of patients' lives directly depends on timely and early diagnosis. The criteria for diagnosing iNG that are used in neuroimaging can also be found in patients without clinical manifestations of this disease, and the widely used tap-test is an invasive technique with a rather low sensitivity.

Immunomorphogenesis in Degenerative Disc Disease: The Role of Proinflammatory Cytokines and Angiogenesis Factors.

Back pain (BP) due to degenerative disc disease (DDD) is a severe, often disabling condition. The aim of this study was to determine the association between the expression level of proinflammatory cytokines (IL-1β, IL-6, and IL-17), angiogenesis markers (VEGF-A and CD31) in intervertebral disc (IVD) tissue and IVD degeneration in young people with discogenic BP. In patients who underwent discectomy for a disc herniation, a clinical examination, magnetic resonance imaging of the lumbar spine, histological and immunohistochemical analyses of these factors in IVD were performed in comparison with the parameters of healthy group samples (controls).

[The problem of pharmacoresistant tremor in Parkinson's disease and essential tremor].

MR-guided focused ultrasound (MRg-FUS) is a new noninvasive method for the treatment of contralateral disabling and pharmacoresistant tremor. Clinical studies have confirmed the high efficacy and safety of using MRg-FUS in patients with essential tremor and Parkinson's disease, in short and long-term studies. Advantages of this method in comparison with currently used invasive and noninvasive technics, potential brain target areas, the possibility of bilateral intervention, indications and contraindications are discussed.

[Dissection of brachiocephalic arteries as a complication of open neurosurgery: case report and literature review].

Background: Abnormal styloid processes cause dissection of supra-aortic arteries in some cases. In total, about 33 cases have been described in the world and national literature. However, there were no dissections associated with neurosurgery.

[COVID-19-associated stroke].

Neurological complications of COVID-19 occur in almost a third of patients. According to various studies, the frequency of cerebrovascular manifestations in patients with a positive test result for SARS-CoV-2 ranges from 1% to 3%. The most common manifestation was acute ischemic stroke.
