The mean time between primary radiotherapy and local recurrence (LR) is 14.1 months [4 - 38]. CK is performed with a dose of 36 Gy in 6 fractions (5 cases) and 30 Gy in 3 fractions (1 case) Results : LR after CK (progression free survival) is 3.4 months [2 - 7] (5 cases assessment). Mean survival after CK is 12 months [3 - 22] (3 cases assessment). Mean survival after initial diagnosis is 37 months [17 - 58] (3 cases assessment). No toxicity is noticed (4 cases assessment). Time to first progression after primary treatment is a strong predictor for survival. Fractionated stereotactic reirradiation with CK is well tolerated and effective (survival) in patients with LR high grade gliomas. In accordance with these results, the CFB Conseil Scientifique recommends a new paradigm for MRI follow-up high grade gliomas. After first line treatment, an MRI has to be performed every 3 months, to identify LR earlier, and to offer the patients a way of salvage with CK option, in order to increase his chances of better survival.</p>","PeriodicalId":72476,"journal":{"name":"Bulletin de la Societe des sciences medicales du Grand-Duche de Luxembourg","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36194934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the last century aging has been associated with decline and decay, but gradually more people lived ably and healthily in older ages. The expansion in life expectancy has become a synchronism of quality of life: the average 65 year old today is much healthier, physically and mentally fitter, than the average 50 year old 150 years ago, when Alois Alzheimer war born, a period when most nowadays existing geriatric institutions were envisioned and progressively realized over time. Today we strongly believe that a healthy life and, equally, the quality of life of the very old people can be extended with presently existing medical knowledge, based on research, environmental and behavioural changes, by postponing the onset and progression of fatal and disabling diseases and disorders. But very soon ethical considerations concerning all kinds of medical and technological solutions available to maintain or even improve the mental and physical functioning of dependant elderly people will engage our society when deciding how and at what moment in time to make the best decisions and allocate resources.

The Direct Flow Medical transcatheter aortic valve (DFM) is a new nonmetallic valve which allows perfect repositioning and valve retrieval prior to the final deployment. This study is a prospective non-randomized evaluation of the DFM system in the Luxembourg registry. The study focused on 15 patients who received between March 2013 and October 2013 a percutaneous aortic valve replacement by DFM prosthesis. All clinical and echocardiographic data have been collected prospectively. Fifteen inoperable patients with severe aortic stenosis were evaluated. The average age of our population was 83 +/- 4.16 years, mean STS score was 16%. 46% of patients were in NYHA class III and 33.3% in NYHA class IV. Mean ejection fraction was 59% +/- 12.7, the average mean gradient was 52.86 +/- 18.5 mm Hg and mean aortic orifie was 0.63 +/- 0.15 cm2. Procedural success rate was 100%. The mean trans- valvular gradient decreased from 52.86 +/- 18.5 mm Hg to 12 +/- 4.2 mm Hg (p < 0.001). The average hospital stay was 14 +/- 7.6 days.

The brain surgeons might find themselves in a difficult situation when they have to decide whether to operate on a patient with a compromised haemostasis or not.

It is usually expressed in maximal oxygen consumption (VO2(max)) or metabolic equivalent (MET) and is measured by spiroergometry or calculated by a regression formula based on maximal performance achieved.
