Rnf213 Gene

Progressive stenosis and occlusion of the bilateral internal carotid artery terminals and circle of Willis are typical features of Moyamoya disease. However, aplastic or twig-like middle cerebral artery (Ap/T-MCA)—wherein the unilateral main trunk of the middle cerebral artery (MCA) is not depicted, and a plexiform arterial network is formed—is similar to the findings of Moyamoya disease. Here, we describe a 78-year-old man who presented with mild right paralysis and aphasia. Magnetic resonance angiography (MRA) at admission did not show the bilateral MCAs. The findings were similar to those of Moyamoya disease, and his symptoms worsened after hospitalization. Endovascular treatment was performed, and the left MCA was completely recanalized. Later, paroxysmal atrial fibrillation was detected, and we finally determined that left MCA occlusion had occurred due to embolism. The right MCA was completely occluded at its origin, indicating an Ap/T-MCA. Embolic occlusion of the unilateral MCA and contralateral Ap/T-MCA made this case resemble Moyamoya disease in the acute stage. Even when chronic occlusion is suspected on MRA in acute cerebral infarction, endovascular treatment should be considered. Additionally, a heterotypic R4810K polymorphism was later found in the RNF213 gene. To our knowledge, this is the second report of Ap/T-MCA with the RNF213 gene polymorphism; however, their association remains unclear and requires further analyses.

Vascular Beds

Unlike many peripheral vascular beds, the sympathetic nervous system exerts little control on cerebral blood flow. The contractile response of isolated rabbit middle cerebral artery (MCA) segments to electrical field stimulation of its intramural nerves is less than in a similar-sized artery from the ear. This study was undertaken to characterize and compare the perivascular neuromuscular relationships and innervation density of similar-sized arteries varying in diameter from these two different regional arterial beds to see if there were structural correlates for these functional differences.

Type Headache

Introduction. According to the defi nition of the World Health Organization (WHO), tension-type headache (TTH) is the most common type of primary headache. Rehabilitation of patients with chronic tension-type headache continues to be an important socio-medical problem. Its main goal is the most complete restoration of the functions of the musculoskeletal system of the neck, the correction of vascular and psychoemotional problems, and the patient′s return to his everyday life and work. As a rule, the main emphasis in the treatment of such patients is placed primarily on drug therapy. At the same time, practitioners are faced with a number of problems — the low effectiveness of the treatment, the nonpersistency of the results, allergic reactions, polypharmacy and others. All this suggests that there is a need for differentiated rehabilitation treatment of patients with tension-type headache with the use of various non-pharaceutical methods. The goal of research — to evaluate the clinical effi cacy of complex non-drug therapy in patients with tension-type headache.Materials and methods. The prospective controlled randomized study, which was conducted from October 2017 to March 2019 at the Department of Medical Rehabilitation of the Bashkir State Medical University, included 110 patients with TTH from the age of 20 to 45 years. All patients, depending on the treatment methodology used, were randomly divided into two groups of 55 people. Patients of the main group received complex rehabilitation treatment with the use of non-drug methods: osteopathic correction, acupuncture and exercise therapy. Patients in the control group received treatment in accordance with the standard of medical care for TTH (analgesics, non-steroidal antiinfl ammatory drugs, antidepressants, vasoactive and nootropic drugs). The study of the clinical effectiveness of the therapy included: an assessment of the severity of pain with the use of a visual analogue scale and a tensoalgimeter, a goniometric study with an assessment of the volume of active movements in the cervical spine, transcranial ultrasound dopplerography with an assessment of quantitative indicators in the system of the middle cerebral artery.Results. The use of complex non-drug therapy in patients with TTH compared with standard drug therapy leads to a signifi cantly more important decrease in the severity of pain, an increase in pain threshold, an increase in the volume of active movements in the cervical spine. The effect of non-drug treatment methods on blood fl ow in the system of the middle cerebral artery is comparable in its effectiveness with the use of pharmaceutical drugs.Conclusion. The proposed complex rehabilitation treatment of patients with TTH with the use of non-drug methods has shown clinical effi cacy which is comparable, and in a number of indicators, superior to the effectiveness of conventional medical treatment. All this determines the necessity of wider implementation of multidisciplinary non-drug treatment of patients with this pathology.
