The aim of the study was to analyse the risk of symptomatic myelopathy after minor trauma in patients with asymptomatic spondylotic cervical spinal cord encroachment (ASCCE). In a cohort of 199 patients with ASCCE, previously followed prospectively in a study investigating progression into symptomatic myelopathy, the authors looked retrospectively for traumatic episodes that may have involved injury to the cervical spine. A questionnaire and data file analysis were employed to highlight whatever hypothetical relationship might emerge with the development of symptomatic myelopathy. Fourteen traumatic episodes in the course of a follow-up of 44 months (median) were recorded in our group (who had been instructed to avoid risky activities), with no significant association with the development of symptomatic myelopathy (found in 45 cases). Only three minor traumatic events without fracture of the cervical spine were found among the symptomatic myelopathy cases, with no chronological relationship between trauma and myelopathy. Furthermore, 56 traumatic spinal cord events were found before the diagnosis of cervical cord encroachment was established, with no correlation to either type of compression (discogenic vs osteophytic). In conclusion, the risk of spinal cord injury after minor trauma of the cervical spine in patients with ASCCE appeared to be low in our cohort provided risky activities in these individuals are restricted. Implementation of preventive surgical decompression surgery into clinical practice in these individuals should be postponed until better-designed studies provide proof enough for it to take precedence over a conservative approach.

Pripravila sa séria 6 nových organických amóniových solí amfifilného charakteru, odvodených odamínalkoholu, všeobecnej štruktúry:CH3(CH2)9CH(OH)CH2N + (CH3)2R Br -R = C6 – C16Súčasťou syntézy uvedených zlúčenín je aj príprava 1-bróm-2-dodekanolu. Sledovali sa agregačnévlastnosti týchto látok vo vodných roztokoch, vyjadrené hodnotami kritickej koncentrácie tvorbymiciel (tab. 2) a antimikróbna aktivita, vyjadrená minimálnou inhibičnou koncentráciou (tab. 3),v závislosti na postupnom predlžovaní alkylového reťazca pri zachovaní základnej štruktúry (2-hyd-roxydodecyl a metyl, naviazané na kvartérny dusík).
The paper describes the preparation of a series of six new organic ammonium salts of amphiphiliccharacter, derived from amine alcohol, of the general structure:CH3(CH2)9CH(OH)CH2N + (CH3)2R Br -R = C6 – C12A part of the synthesis of the above-mentioned compounds is also the preparation of 1-bromo-2-do-decanol. The aggregation properties of these compounds in aqueous solution, expressed by the valuesof the critical concentration of micelle formation (Table 2), and antimicrobial activity, expressed bythe minimum inhibitory concentration (Table 3), in dependence on the step-by-step lengthening ofthe alkyl chain while preserving the principal structure (2-hydroxydodecyl and methyl bound to thequaternary nitrogen) were examined.
