Operative retrieval of two proximally migrated vena caval filters was performed in two patients, ages 42 and 45 years, respectively. In the first patient the filter was encrusted in the right ventricle, and in the second one the filter was found in the pulmonary artery. Both filters were retrieved under cardiopulmonary bypass via an incision in the right atrium and the pulmonary artery, respectively. These two observations underscore the risk of increased unwarranted indications and consequent higher complication rates of vena caval filters. [less ▲]

Introduction : Certaines tendinopathies (l’épicondylite, la tendinopathie rotulienne supérieure ou encore la tendinopathie d’Achille) demeurent rebelles malgré un traitement « classique » bien conduit : repos, orthèse, AINS, électrothérapie, kinésithérapie, infiltrations de corticoïdes, ondes de choc... Certains travaux, essentiellement in vitro, soulignent les potentialités réparatrices des plaquettes qui présentent la capacité d’accélérer la cicatrisation de différents tissus : os, muscles et tendons. Objectifs : Le but de notre étude préliminaire est d’objectiver l’effet « accélérateur » sur la réparation tendineuse suite à l’emploi d’injection de plasma enrichi en plaquettes (platelet-rich plasma ou PRP) car cette technique pourrait représenter une thérapeutique d’avenir en médecine physique et en traumatologie du sport. Méthodes : Nous avons sectionné et réalisé un défect de 5mm dans le tendon d’Achille de rats (N = 12). Quatre rats ont bénéficié d’une injection in loco de PRP et remis en liberté comme les autres dans leur cage. Trois rats (2 sans PRP et 1 avec PRP) sont euthanasiés à J5, J10, J20 et J30 et le tendon d’Achille en cours de régénération est disséqué et prélevé. Une étude biomécanique de traction jusqu’à rupture est réalisé à l’aide de « Cryo-jaw ». Résultats : L’analyse des résultats montre que la force développée pour obtenir la rupture tendineuse doit être plus importante pour les tendons ayant bénéficié d’une injection de PRP et ce dès J5. Discussion – Conclusion : Cette série préliminaire permet de montrer que les injections de PRP permettent une accélération de la cicatrisation tendineuse et une augmentation des valeurs de résistances à la traction. Une étude avec un plus grand nombre de sujets est en cours. [less ▲]

Growing amount of high dimensional data requires robust analysis techniques. Tree-based ensemble methods provide such accurate supervised learning models. However, the model complexity can become utterly huge depending on the dimension of the dataset. Here we propose a method to compress such ensemble using random tree induced space and L1-norm regularisation. This leads to a drastic pruning, preserving or improving the model accuracy. Moreover, our approach increases robustness with respect to the selection of complexity parameters. [less ▲]

See detailPSA kinetics after external beam radiotherapy alone or combined with an iridium brachytherapy boost to deliver 85 grays to prostatic adenocarcinoma.

PURPOSE: Increasing the dose to prostatic adenocarcinoma in conformal external beam therapy (EBT) has resulted in increased levels of PSA normalization and increased percentage of biochemical disease-free survival rates. However technical problems due to prostate motion inside the pelvis or patients' set-up make difficult the realization of the EBT boost fields above 72 Gy. Brachytherapy which overcomes these problems was investigated to deliver the boost dose to achieve 85 Gy. PSA nadir which has been identified as the strongest independent predictor of any failure in many studies has been used as the end point for early evaluation of this work. PATIENTS AND METHODS: In a retrospective way we report on 163 patients' PSA kinetics after EBT alone to 68 Gy or EBT first and a brachytherapy boost up to 75 or 85 Gy. RESULTS: At 12 months follow-up, PSA nadirs percentage < or = 0.5 or < or = 1 ng/ml increased from 7.5 and 20.7% after 68 Gy EBT to 49.8 and 71.2% after a brachytherapy boost to deliver 85 Gy (p < 0.0001). In the Cox PH model analysis, the total dose remained the most important factor for predicting PSA normalization. CONCLUSIONS: These results are in accordance with the most recent results published after conformal EBT at the same 80 Gy level of dose. If confirmed on a higher number of patients they could place brachytherapy among the most accurate methods of boosting in the radiation treatment of prostatic carcinoma. [less ▲]

Aortic pseudo-aneurysm is a well-known late complication after surgical repair of aortic coarctation. We report two cases of pseudo-aneurysm of the aortic isthmus evidenced after previous surgical repair of congenital aortic coarctation. These clinical observations give us the opportunity to underline the importance of a specific lifelong medical follow-up for patients who have undergone such surgery. [less ▲]

This report is devoted to the elastic response of hyperbolic notch hinges. Circular, elliptic and parabolic notch hinges have been treated in ealier reports. The adopted step is the same : firstly, for each fundamental load case, the analytical solution is developed in the frame of the classical beam theory ; from this, the asymptotic solution for very narrow hinges is produced ; thirdly, a correction factor is defined, which relates the exact theory to the asymptotic one ; finally, and this is perhaps our main originality, simple but very fair approximations of these correction factors are presented.

Cette démarche fournit des solutions très bien approchées et beaucoup plus simples à utiliser que celles de la littérature, un fait appréciable au niveau de la conception. [less ▲]

Pseudo-Bartter syndrome presents the same clinical and biological characteristics as Bartter syndrome but without primary renal tubule abnormalities. We relate the case of a premature baby presenting at birth with severe hypokalemic metabolic alkalosis associated with hyponatremia and hypochloremia. Maternal blood at the time of delivery showed the same electrolyte perturbations. The baby's mother had suffered from anorexia and vomiting during pregnancy. A few weeks after birth the baby's blood abnormalities had almost returned to normal. Chloride depletion is at the origin of both maternal and fetal hypokalemic alkalosis. [less ▲]
