Process-Optimized Minimally Invasive Total Hip Replacement via a Direct Anterior Approach with Navigation Control of Leg Length and Offset
2013
The purpose of this study was to analyze a new concept of using the minimally invasive direct anterior approach (DAA) in total hip replacement (THR) in combination with a leg positioner (Rotex-Table) and a modified retractor system (Condor). To control leg length and offset, the navigation system OrthoPilot® (B. Braun, Aesculap) or the Medacta system was used. We retrospectively evaluated the first 100 primary THRs performed with this new concept between 2009 and 2010, regarding the surgical data as well as the radiological and clinical outcome (Hip Disability and Osteoarthritis Outcome score, HOOS). All surgeries were perfomed following a standardized operation technique including navigati…
Perinatal high-fat diet increases hippocampal vulnerability to the adverse effects of subsequent high-fat feeding
2015
Epidemiological observations report an increase in fat consumption associated with low intake of n-3 relative to n-6 polyunsaturated fatty acids (PUFAs) in women of childbearing age. However, the impact of these maternal feeding habits on cognitive function in the offspring is unknown. This study aims to investigate the impact of early exposure to a high-fat diet (HFD) with an unbalanced n-6/n-3 PUFAs ratio on hippocampal function in adult rats. Furthermore, we explored the effects of perinatal HFD combined with exposure to HFD after weaning. Dams were fed a control diet (C, 12% of energy from lipids, n-6/n-3 PUFAs ratio: 5) or HFD (HF, 39% of energy from lipids, n-6/n-3 PUFAs ratio: 39) th…
Zwei Fälle von Humeruskopfosteolyse unklarer Genese
2008
Taking in account the medical history, the clinical and radiological presentation and the intraoperative and histological findings, two cases of osteolysis of the humeral head of unknown origin are discussed. After exclusion of underlying concomitant diseases a traumatic etiology seemed to be the most probable explanation although in both cases a trauma was denied by the patients. We are unaware of any similar cases published in the literature.
Ankle muscle strength discriminates fallers from non-fallers
2014
International audience; It is well known that center of pressure (CoP) displacement correlates negatively with the maximal isometric torque (MIT) of ankle muscles. This relationship has never been investigated in elderly fallers (EF). The purpose of this study was thus to analyze the relationship between the MIT of ankle muscles and CoP displacement in upright stance in a sample aged between 18 and 90 years old that included EF . The aim was to identify a threshold of torque below which balance is compromised. The MIT of Plantar flexors (PFs) and dorsal flexors (DFs) and CoP were measured in 90 volunteers: 21 healthy young adults (YA) (age: 24.1 +/- 5.0), 12 healthy middle-aged adults (MAA)…
Executive summary of the joint position paper on renal denervation of the Cardiovascular and Interventional Radiological Society of Europe and the Eu…
2016
Renal denervation (RDN) was reported as a novel exciting treatment for resistant hypertension in 2009. An initial randomized trial supported its efficacy and the technique gained rapid acceptance across the globe. However, a subsequent large blinded, sham arm randomized trial conducted in the USA (to gain Food and Drug Administration approval) failed to achieve its primary efficacy end point in reducing office blood pressure at 6 months. Published in 2014 this trial received both widespread praise and criticism. RDN has effectively stopped out with clinical trials pending further evidence. This joint consensus document representing the European Society of Hypertension and the Cardiovascular…
Progressive multi-organ expression of immunoglobulin G4-related disease: A case report.
2012
A 63-year-old Caucasian man presented with a cholestatic syndrome, renal failure and arthralgias. A laboratory examination revealed high immunoglobulin G (IgG) and IgG4 levels (5.95 g/L; normal range: 0.08-1.4 g/L), pointing to a diagnosis of systemic IgG4-related disease, with definite radiological evidence of biliary and pancreatic expression, and plausible renal, articular, salivary and lacrimal glands involvement. Due to the rarity of the condition, there are currently no random control trials to point to the optimal therapeutic approach. The patient has been on steroid therapy with the subsequent introduction of azathioprine, with a complete resolution of all symptoms, a rapid reductio…
Palatal perforations secondary to inhaled cocaine abuse: presentation of five cases
2010
The estimated incidence of complications associated with cocaine abuse is 4.8%. Palatal perforation is a very infrequent condition within the range of complications associated with cocaine abuse. No epidemiological cha- racteristics relating to patient age or gender have been established, and the diagnosis of the disorder requires a detailed clinical history, including antecedents of cocaine abuse. The clinical and radiological studies show palatal bone erosion and perforation of the soft or hard palate. The present study describes five cases of palatal perforation secondary to inhaled cocaine abuse. As a result of the increase in cocaine use in recent years, particularly among young adults…
Reconstruction of vertebral body after radiofrequency ablation and augmentation in dorsolumbar metastatic vertebral fracture: Analysis of clinical an…
2017
Background: Painful spinal metastases usually occur in malignant neoplastic disease. Treatment for bone metastases has been largely conservative, and it includes the use of high doses of analgesics, radiotherapy, chemotherapy, hormone therapy, and bisphosphonates; however, results are sometimes transient and ineffective. In the presence of neurological involvement a surgical strategy should be considered. Recently, percutaneous procedures such as radiofrequency ablation, vertebroplasty, and kyphoplasty have been introduced as palliative techniques to treat painful vertebral metastases [3, 11, 25]. Methods: In our study we combined the use of radiofrequency ablation with vertebroplasty in th…
Feasibility of future epidemiological studies on possible health effects of mobile phone base stations.
2006
The increasing deployment of mobile communication base stations led to an increasing demand for epidemiological studies on possible health effects of radio frequency emissions. The methodological challenges of such studies have been critically evaluated by a panel of scientists in the fields of radiofrequency engineering/dosimetry and epidemiology. Strengths and weaknesses of previous studies have been identified. Dosimetric concepts and crucial aspects in exposure assessment were evaluated in terms of epidemiological studies on different types of outcomes. We conclude that in principle base station epidemiological studies are feasible. However, the exposure contributions from all relevant …
Practical recommendations for the application of DE 59/2013
2019
The changes introduced with Council Directive 2013/59/Euratom will require European Member States adapt their regulations, procedures and equipment to the new high standards of radiation safety. These new requirements will have an impact, in particular, on the radiology community (including medical physics experts) and on industry. Relevant changes include new definitions, a new dose limit for the eye lens, non-medical imaging exposures, procedures in asymptomatic individuals, the use and regular review of diagnostic reference levels (including interventional procedures), dosimetric information in imaging systems and its transfer to the examination report, new requirements on responsibiliti…
