«VALIDITY» OR THE «SIGNIFICANCE» — 12 YEARS LATER

The consequences of misuse of the term «validity» in the Russian medical literature are presented. The hypothesis that the replacement of the term «statistical significance» by the widespread term «validity» depending on the context can lead to a distortion of the research perception in general is being checked. It is shown that the mechanisms of this process can be described in terms of the theory of the formation of mythological constructs of the French structuralism school, as well as on the basis of representations of memetics. The recommendations for researchers and editors of medical publications on the right and the best optimal use of those terms and the context language. Key words: scientific terminology, validity, significance, scientometrics, linguistic analysis, semantics, myths formation, memetics. (Pediatric Pharmacology. — 2011; 8 (5): 13–19.

(Pediatric Pharmacology. — 2011; 8 (5): 13–19.)Представлены последствия неправильного употребления термина «достоверность» в российских медицинских публикациях. Проверяется гипотеза о том, что замена термина «статистическая значимость» на широко распространенный термин «достоверность» в зависимости от контекста способна приводить к искажению восприятия исследования в целом. Показано, что механизмы этого процесса могут быть описаны в терминах теории образования мифологических конструктов французской школы структурализма, а также на основе представлений меметики. Даны рекомендации для исследователей и редакторов медицинских изданий по правильному и наиболее оптимальному употреблению упомянутых терминов и языка контекста. Ключевые слова: научная терминология, достоверность, статистическая значимость, наукометрия, лингвистический анализ, семантика, мифообразование, меметика.

Endovascular treatment of a patient with traumatic dissection lesions of both vertebral arteries obtained during chiropractic manipulation

The observation of endovascular treatment of a 34-year-old woman with bilateral dissection lesions of vertebral arteries in V4-segments with occlusion of the right vertebral artery and right posterior inferior cerebellar artery, severe stenosis of the left vertebral artery caused by chiropractic manipulation in the neck region is described. There are intensive staticolocomotor and dynamic coordinating insufficiency, severe neck pain, headache, severe dizziness, Wallenberg syndrome, moderate central tetraparesis. MRI of the brain on the DWI Isotropic identified the hyperintensive round-shaped foci in the right hemisphere of the cerebellum, in the right side of cerebellum worm, in the right side of the medulla oblongata and in the right side of the pons (DWI BSS 3). Selective cerebral angiography was performed an hour after the clinic manifestation. Simultaneously, balloon angioplasty of severe dissection stenosis was performed in the V4-segment of the left vertebral artery by the compliant balloon-catheter Scepter C. In 18 hours from the development of vertebral artery dissection, self-expending stent LVIS was implanted into the left vertebral artery in the zone of dissection lesion. On the control angiograms: the left vertebral artery patency is restored without stenosis all along. The stent is fully opened. A second contrast contour is determined outside the stent in the dissection zone. All the arteries of the vertebrobasilar basin above the vertebrobasilar junction are passable. The V4-segment of the right vertebral artery is contrasted through the vertebrobilar junction. There was a rapid regression of neurological symptoms in the postoperative period. Only mild hypoesthesia on the right side in the outer Sölder’s zone, light coordination disorders on the right were remained. Control selective cerebral angiography revealed recanalization of the right vertebral artery and the right posterior cerebellar artery. But distal basin of the right posterior cerebellar artery is very poorly. The left vertebral artery is passable all over, but in the place of the former dissection, two equivalent arterial «sleeves» were formed according to the fenestration type. One «sleeve» is formed by a stent, the other — outside. All arteries of the vertebrobasilar basin are contrasted. The mild hemihepesthesia on the right side of the face in the outer Sölder’s zone, light coordination disorders on the right are remained. Implantation of the self-expanding stent LVIS allowed to restore the dominant vertebral artery and restrict ischemic brain damage in the brain stem and cerebellum in a patient with a both vertebral arteries dissection lesion caused by chiropractic neck manipulations
