Центральный понтинный миелинолиз (ЦПМ) -это острая ограниченная симметричная невоспалительная демиелинизация в области средней части основания моста мозга. У 10% пациентов с ЦПМ демиелинизация возникает и за пределами моста: средний мозг, таламус, базальные ган-глии и мозжечок [1]. ЦПМ впервые был описан в 1959 г. R.D. Adams и соавт. в докладе о четырех пациентах с псевдобульбарным синдромом и тетраплегией [2]. Данные симптомы были выявлены у пациентов с алкогольной зависимостью и дефицитом питания. К концу 70-х годов прошло-
The paper discusses the reasons of frequent comorbidity of hypertension and chronic pain syndrome. The pathogenesis of both conditions includes dysfunction of same anatomical structures of the central nervous system. According some observation, chronic pain syndrome significantly increases the risk of hypertension. The conditions share common risk factors like old age, decrease of physical activity, obesity, etc. Both conditions are accompanied by the increase in concentration of the factors of systemic inflammation of blood, cognitive impairment and depression. The paper presents case report of the patient with the association of hypertension and chronic pain syndrome.
Неврология, нейропсихиа-трия, психосоматика. 2016;8(4):57-61.Hypertension and pain threshold Grinyuk V.V., Zakharov V.V., Vakhnina N.V. Department of Nervous System Diseases and Neurosurgery, I.M. Sechenov First Moscow State Medical University, Ministry of Health of Russia, Moscow, Russia 11, Rossolimo St., Moscow 119021 The paper considers the relationship between pain threshold and blood pressure (BP) in acute and chronic pain syndrome. Both experimental and clinical studies have established that elevated BP is accompanied by a higher pain threshold in acute pain (hypertension-related hypoalgesia). Epidemiological findings have shown that the prevalence of different pain syndromes is significantly lower in hypertensive patients than in individuals without hypertension. At the same time, there is evidence that elevated BP can, on the contrary, reduce pain thresholds and make prognosis worse in patients with chronic pain syndromes.Keywords: pain threshold; hypertension; chronic pain syndrome.

Кроме то-го, перенесенное сосудистое событие, как и хроническая боль, сопровождается уменьшением физической активно-сти пациентов [4].Однако, помимо общности факторов риска, обсужда-ется также причинно-следственная связь между АГ и хро-ническими болевыми синдромами, о чем свидетельствует ряд экспериментальных и клинических наблюдений [6].Г и п о а л г е з и я п р и а р т е р и а л ь н о й г и п е р т е н з и и : э к с п е р и м е н т а л ь н ы е и с с л е д о в а н и я Со времен появления теории стресса Г. Селье извест-но, что острая боль -это стресс, который вызывает актива-цию симпатико-адреналовой и гипоталамо-гипофизарно-надпочечниковой систем. Активация последней стимули-рует симпатическую нервную систему. Преобладающее влияние симпатической нервной системы по сравнению с парасимпатической ведет к повышению сосудистого со-противления, увеличению частоты и силы сердечных со-кращений и в итоге -к повышению артериального давле-ния (АД) [6].В свою очередь острое повышение АД способствует уменьшению болевой чувствительности. Впервые это было показано B.R. Dworkin и соавт. в 1979 г. [7]. Авторы вызыва-ли искусственное повышение АД у крыс путем введения фе-нилэфрина. После повышения АД у экспериментальных животных раздражали ядро тройничного нерва и анализи-ровали реакцию избегания раздражающего стимула. У крыс с повышенным АД она была замедленной по сравнению с контрольной группой животных. Был сделан вывод, что по-вышение АД способствует уменьшению болевой чувстви-...
Objective: non-interventional study ELBRUS (Etoricoxib in the Treatment of Back Pain) was conducted to investigate the efficacy and safety of daily administration of Rixia® (Etoricoxib) 60 mg per day in patients with chronic non-specific low back pain (CNSLBP).Patients and methods. The study included 50 patients (31 women and 19 men, mean age 54.3±16.8 years) with CNSLBP. Educational conversation, cognitive therapy, regular therapeutic exercises, identification and treatment of comorbidities were conducted. Patients received etoricoxib 60 mg once daily. Pain intensity was assessed on a 10-point numerical rating scale (NRS), pain-related disability was assessed on the Oswestry Scale (ODS), and emotional state was assessed on the Hospital Anxiety and Depression Scale (HADS).Results and discussion. The causes of CNSLBP were: in 5 (10%) patients – sacroiliac joint involvement, in 14 (28%) – lower lumbar facet joints involvement, in 3 (6%) – myofascial pain, the remaining 28 (56%) patients had a combination of several reasons. As a result of complex treatment, the intensity of pain at rest decreased on average from 4.0±2.5 to 1.4±1.3 points, while moving – from 6.6±1.9 to 2.8±1.8 points, at night – from 2.7±2 to 0.7±0.9 points according to the NRS, disability – from 39±18.9 to 19.9±14.6% according to the ODS, the severity of anxiety – from 6.5±3.9 to 3.3±2.4 points and depression from 5.0±3.7 to 3.1±2.9 points according to HADS (p<0.001). The duration of treatment was 14.14±3.6 days on average. No adverse events were observed during treatment with etoricoxib. Conclusion. The efficacy and safety of etoricoxib in the complex therapy of patients with CNSLBP was noted.

Isolated oculomotor disorders caused by central nervous system damage are quite rare. As a rule, they are combined with other signs of cerebral trunk damage. A clinical case with the focus of amyelination in the cerebral trunk area, which manifests itself in the form of bilateral horizontal gaze palsy in the absence of other focal neurological symptoms is presented. A complete regression of oculomotor disorders was observed against the background of glucocorticosteroid therapy. A differential research was carried out among amyelinating, ophthalmic, endocrinologic diseases, ANCA-associated vasculitis (AAV).
