Plasma wakefield accelerators driven by particle beams are capable of providing accelerating gradient several orders of magnitude higher than currently used radio-frequency technology, which could reduce the length of particle accelerators, with drastic influence on the development of future colliders at TeV energies and the minimization of x-ray free-electron lasers. Since interplasma components and distances are among the biggest contributors to the total accelerator length, the design of staged plasma accelerators is one of the most important outstanding questions in order to render this technology instrumental. Here, we present a novel concept to optimize interplasma distances in a staged beam-driven plasma accelerator by drive-beam coupling in the temporal domain and gating the accelerator via a femtosecond ionization laser.

The gold standard treatment for enchondroma in the hand is curettage and filling of the defect. The goal of this study was to evaluate the results when injectable calcium phosphate cement is used to fill the bone defect. Eight patients having a mean age of 44 years were operated through a minimally invasive skin incision.

Material And Methods: Three hundred and eighty-eight plates removed from 387 patients (357 females: mean age, 50 years) were assessed retrospectively. The incision used the primary minimally invasive approach and was closed after plate removal by intradermal continuous suture, without drainage or immobilization.
The Région Languedoc Roussillon is the umbrella organisation for an interconnected and integrated project on active and healthy ageing (AHA). It covers the 3 pillars of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA): (A) Prevention and health promotion, (B) Care and cure, (C) and (D) Active and independent living of elderly people. All sub-activities (poly-pharmacy, falls prevention initiative, prevention of frailty, chronic respiratory diseases, chronic diseases with multimorbidities, chronic infectious diseases, active and independent living and disability) have been included in MACVIA-LR which has a strong political commitment and involves all stakeholders (public, private, patients, policy makers) including CARSAT-LR and the Eurobiomed cluster.

Complications include unstable fixation, K-wire migration, septic arthritis and osteoarthritis. To limit these complications, we wanted to explore the benefits of using locked extra-articular DIP pinning.

The primary aim of this study was to show that joint preparation for DIP fusion is not necessary in cases of stage IV chondropathy. The secondary aim was to show that use of buried compression screws decreases the complication rate.

We report on three clinical cases of finger injuries caused by pre-weakened rings. Lesions were less severe than conventional ring finger injuries, such as those caused by iron fences.
