Abstract
BACKGROUND Pulmonary metastasectomy of renal cell carcinomas (RCC) remains controversial. Thoracic lymph node involvement (LNI) is a known prognostic factor. The aim of our analysis is to evaluate whether patients with LNI, and particularly N2 patients, should be excluded from surgical treatment. METHODS We retrospectively reviewed data from 122 patients who underwent operations at two French thoracic surgery departments between 1993 and 2011 for RCC lung metastases. RESULTS The population consisted of 38 women and 84 men; the average age at time of metastasectomy was 63.3 years (min: 43, max: 82). LNI was identified as a prognostic factor using univariate and multivariate analysis (median survival: 107 months vs. 37 months, P = 0.003; HR = 0.384 (0.179; 0.825), P = 0.01, respectively). Although differences in survival between metastases at the hilar and mediastinal locations were not significant (median survival: 74 months vs. 32 months, respectively, P = 0.75), length of survival time was associated with disease-free interval less than 12 months (median survival: 23 months vs. 94 months, P < 0.0001; HR = 3.081 (1.193; 7.957), P = 0.02). CONCLUSION Although LNI has an adverse effect on survival; long-term survival can be achieved in pN+ patients. Consequently, these patients should not be excluded from surgery. Systematic lymphadenectomy should be performed to obtain more accurate staging and to determine appropriate adjuvant treatment.

Abstract
Adaptation to new environments is a key feature in evolution promoting divergence in morphological structures under selection. The house mouse (Mus musculus domesticus) introduced on the Sub-Antarctic Guillou Island (Kerguelen Archipelago) had and still has to face environmental conditions that likely shaped the pattern and pace of its insular evolution. Since mouse arrival on the island, probably not more than two centuries ago, ecological conditions dramatically differed from those available to their Western European commensal source populations. In addition, over the last two decades, the plant and animal communities of Guillou Island were considerably modified by the eradication of rabbits, the effects of climate change and the spread of invasive species detrimental to native communities. Under such a changing habitat, the mouse response was investigated using a morphometric quantification of mandible and molar tooth, two morphological structures related to food processing. A marked differentiation of the insular mice compared with their relatives from Western Europe was documented for both mandibles and molar shapes. Moreover, these shapes changed through the 16 years of the record, in agreement with expectations of drift for the molar, but more than expected by chance for the mandible. These results suggest that mice responded to the recent changes in food resources, possibly with a part of plastic variation for the mandible prone to bone remodelling. This pattern exemplifies the intricate interplay of evolution, ecology and plasticity that is a probable key of the success of such an invasive rodent facing pronounced shifts in food resources exploitation under a changing environment.

Robotic-assisted thymectomy with Da Vinci II versus sternotomy in the surgical treatment of non-thymomatous myasthenia gravis: early results. Rev Neurol (Paris) 2012; 169:30-6.

Abstract
BACKGROUND The role of thymectomy in myasthenia gravis remains controversial. The remission rate 5years after surgery varies from 13 to 51% in the literature. Sternotomy is the standard technique, though unacceptable by patients because of significant esthetic sequelae. Our objective was to demonstrate that the robot-assisted technique using the Da Vinci Surgical Robot II is at least as efficient and leaves fewer scars than the standard surgical technique. METHODS We retrospectively reviewed the data of 31 consecutive patients suffering from myasthenia gravis who underwent surgery in our center from January 1998 to March 2010. Ten patients with thymoma were excluded from this study. Two groups were formed: group 1 corresponding to patients treated with sternotomy, group 2 patients with robot-assisted technique. The duration of the hospital stay, the pain on D1, the degree of improvement at 1year according to Myasthenia Gravis Foundation of America (MGFA) classification, the frequency of relapses, and perioperative treatment were studied. RESULTS Our sample consisted of 14 women and seven men. The mean age was 31.3years. The mean delay before surgery was 24months. Group 1 included 15 patients and group 2 had six patients. The complete remission rate at 1year was 9.5% (n=2). Surgery decreased the frequency of relapses after surgery (P=0.08) equally in the two groups. The duration of hospital stay and the pain level on D1 in group 2 were significantly lower than those in group 1 (P=0.02 and P<0.001). The degree of postoperative improvement was not significantly different between the two groups (P=0.31). CONCLUSION The results at 1year are fully comparable for sternotomy and the robot-assisted technique. The robot provides additional benefits of minimally invasive techniques: minimal esthetic sequelae in often young patients, less parietal morbidity (including pain), shorter hospital stays. Our complete remission rate, lower than those in the literature, must be considered taking into account the early nature of these results. The surgical robot, because of its many advantages, appears to be a promising technique and should facilitate the early management of these patients.

Abstract
Massive hemoptyses are serious clinical conditions that can quickly jeopardize the vital prognosis. The major risk is asphyxiation, due to the bleeding into the tracheobronchial tree. The clinician should provide in parallel support for diagnosis and treatment, locating the bleeding but also finding its cause. Such patients should be cared for by a multidisciplinary team, having quick access to an important technical support. The association fiberoptic bronchoscopy-chest CT scan seems to be the most effective to locate and identify the cause of the bleeding. The development of bronchial artery embolization has revolutionized the management of these patients, replacing surgery in many of its indications. The latter still keeps a place in the management of these patients. Indeed, it is the main etiological treatment, preventing the vast majority of recidivism. It is absolutely indicated in the treatment of bleeding from the pulmonary vessels, and in case of failure of other techniques. It should be performed whenever possible away from the episode of hemoptysis, in order to minimize the operative risk.

Abstract
DNA microarray analysis is a powerful tool for simultaneous analysis and comparison of gene products expressed in normal and diseased tissues. We used this technique to identify differentially expressed genes (DEGs) in nerve biopsy samples of vasculitic neuropathy (VAS) patients. We find novel previously uncharacterized genes of relevance to VAS pathogenesis. Genes upregulated in VAS include IGLJ3, IGHG3, IGKC, and IGL, which all function in B-cell selection or antigen recognition of B cells. Other upregulated genes are chemokines, such as CXCL9 and CCR2 and CX3CR1. Allograft inflammatory factor-1 (AIF-1), a modulator of immune response is upregulated in VAS. We demonstrate by immunolocalisation the expression of AIF-1 in vascular smooth muscle cells, suggesting a role for AIF-1 in vascular remodeling in VAS. Microarray-based analysis of human nerve biopsies shows distinct gene expression patterns in VAS. DEGs might provide clues to the pathogenesis of this condition and help define potential targets for therapeutics.

Abstract
A 30-year analysis of 128 patients with flexor tendon sheath ganglion was investigated. The majority of patients were females with sex ratio of 2.6 : 1. Most of the patients are in their third to fifth decade of life. Hand dominance, previous trauma as well as other illnesses involving the hand did not show any correlation to the formation of ganglion. The middle finger was most commonly affected and 69% of the ganglion were located on A1 and A2 pulley. Recurrence was high (89%) after multiple percutaneous puncture and treatment was successful with no cases of recurrence after surgical excision.

Abstract
In this paper, we present a library of analog operators used for the analog real-time computation of the Hodgkin-Huxley formalism. These operators make it possible to design a silicon (Si) neuron that is dynamically tunable, and that reproduces different kinds of neurons. We used an original method in neuromorphic engineering to characterize this Si neuron. In electrophysiology, this method is well known as the "voltage-clamp" technique. We also compare the features of an application-specific integrated circuit built with this library with results obtained from software simulations. We then present the complex behavior of neural membrane voltages and the potential applications of this Si neuron.
