This cross sectional study focused on how Postural Stability (PS) indicators: body sway deviation (BSD) and body sway velocity (BSV), change with age and their association with levels of social and physical activity. Observational study: 80 older adults (aged: 60-96) were purposefully recruited from two sources: the University of the Third Age (TAU) (n = 35) and a residential care home (CH) (n = 45). Differences in the indicators of PS, approximated through Centre of Pressure (COP) measurements, were assessed by the Romberg Stance Test (Test A) subsequently repeated on 10 cm foam surface (Test B), using a Kistler Dynamometric Platform. The RCH Group was older, had higher BMI and was less socially and physically active, showed more body sway in all indicators compared to TAU group. For all participants body sway velocity (BSV) was significantly correlated with age. The strength of correlation of body sway deviation (BSD) with age was also significant but not as strong. The findings indicate in line with previous studies that deterioration in BSV is associated with poor PS more than deterioration in BSD. and J. Jančová Všetečková, N. Drey
Úvod: Kompletní resekce je obecně uznávaný standard léčby GII ependymomů IV. komory u dospělých, zatímco role adjuvantní radioterapie zůstává nejistá. Účelem předkládané studie je zhodnotit lokální kontrolu onemocnění a klinický stav pacientů s tímto onemocněním po chirurgické terapii. Materiál a metody: Retrospektivně jsme zhodnotili 15 pacientů (sedm mužů a osm žen) s histologicky verifikovaným GII ependymomem IV. komory v časovém období leden 2001–prosinec 2011. Výsledky: Kompletní resekce tumoru byla dosažena u 12 pacientů, u žádného z nich nebyla indikována adjuvantní radioterapie. Medián dalšího sledování byl 51 měsíců (min.–max.; 11–123 měsíců). Ke grafické recidivě došlo u jednoho pacienta, ten byl reoperován s časovým odstupem 51 měsíců od prvního zákroku. Nový neurologický deficit po operaci byl zaznamenán ve dvou případech. U dvou ze tří pacientů po subtotální resekci došlo ke grafické progresi rezidua po 11 a 16 měsících od první operace, jeden z nich byl reoperován s odstupem 27 měsíců. Adjuvantní radioterapie byla indikována u obou pacientů po reoperaci. Závěr: Dle našich dat je kompletní resekce efektivní a bezpečná léčba GII ependymomů IV. komory u dospělých. Následná radioterapie by měla být rezervována pro případy subtotální resekce s následnou progresí rezidua tumoru a reoperace., Introduction: Surgical resection is a generally accepted standard treatment modality in GII posterior fossa ependymomas in adults, while the role of adjuvant radiotherapy remains unclear. The purpose of this study was to evaluate local control of tumor growth and clinical outcome of patients after surgical treatment of GII fourth ventricle ependymomas. Material and methods: We conducted a retrospective study of 15 adult patients (seven males and eight females) with histologically confirmed GII fourth ventricular ependymoma between January 2001 and December 2011. Results: Gross total resection was achieved in 12 patients, none of them received adjuvant treatment after the initial surgery. Median follow-up after GTR was 51 months (min. – max.; 11–123 months). One patient showed radiographic signs of tumor recurrence and was re-operated 51 months after the initial surgery. Remaining patients were without any signs of tumor recurrence. After the surgery, a new neurological deficit occurred in two patients. Two of the three patients after subtotal tumor resection showed residual mass progression after 11 and 16 months postoperatively, one of them was re-operated 27 months after the initial surgery. Adjuvant radiotherapy was indicated in both re-operated patients. Conclusion: According to our data, gross total resection is effective and safe treatment of GII fourth ventricle ependymomas. Adjuvant radiotherapy should be reserved for the cases where complete removal of tumor mass is not possible and residual tumor is growing, or after repeated resection.
