International perspectives on general internal medicine and the case for "globalization" of a discipline.

General internal medicine (GIM) has flourished in the United States (U.S.). Unlike other subspecialties of internal medicine, however, GIM's evolution has not been global in scope, but rather appears to have occurred in isolation within countries. Here, we describe international models of GIM from Canada, Switzerland, Australia/New Zealand, Argentina, and Japan, and compare these with the U.S. model. There are notable differences in the typical clinical roles assumed by General Internists across these 7 countries, but also important overlap in clinical and academic domains. Despite this overlap, there has been a relative lack of contact among General Internists from these and other countries at a truly international GIM meeting; the time is now for increased international exchange and the "globalization" of GIM.

Médecine interne: le point de vue du chef de clinique [Internal medicine: the point of view of the chief resident].

Clinical practice in internal medicine has fundamentely changed over the last decade. Our knowledge has dramatically improved and we are facing new types of patients. Their number is increasing, they are older and suffer from increasingly complex medical conditions. The society has evolved as well therefore transforming our daily practice. This implies important modifications of our role and new challenges. We must also develop new aspects of our practice such as recognizing our errors, quality of care, quality of education, ethics, new strategies for taking care of the patient all this in parallel with continuous education. Our role as (general practitioner) is of utmost importance since it enables us to keep the "big pictures" in a more and more specialized environment.

Nouveau programme de formation en médecine interne générale: implications pour les médecins de premier recours [The new postgraduate training program in general internal medicine: implications for the primary care physician].

The Swiss postgraduate training program in general internal medicine is now designed as a competency-based curriculum. In other words, by the end of their training, the residents should demonstrate a set of predefined competences. Many of those competences have to be learnt in outpatient settings. Thus, the primary care physicians have more than ever an important role to play in educating tomorrows doctors. A competency-based model of training requires a regular assessment of the residents. The mini-CEX (mini-Clinical Evaluation eXercise) is the assessment tool proposed by the Swiss institute for postgraduate and continuing education. The mini-CEX is based on the direct observation of the trainees performing a specific task, as well as on the ensuing feedback. This article aims at introducing our colleagues in charge of residents to the mini-CEX, which is a useful tool promoting the culture of feedback in medical education.

Thérapeutique et médecine interne générale [Therapy and internal medicine].

This review is based on five articles published in 2006 and dealing with therapies in general internal medicine: in case of acute non complicated rhino-sinusitis, the use of topical corticoids in mono-therapy is indicated; cross-reactivity between penicillins and cephalosporins is less frequent than established so far. In our daily practice we should be more "pro-active" in prescribing probiotics which have proved their efficacy in the prevention of antibiotic-associated diarrhoeas; an antibiotic treatment of three days is recommended in case of non complicated cystitis in women less than 65 years of age. Finally, every patient treated with bisphosphonates must be regularly followed by a dentist.

Venture capital financing : screening and contracting under assymetric information

Structure of the Thesis This thesis consists of 5 sections. Section 1 starts with the problem definition and the presentation of the objectives of this thesis. Section 2 introduces a presentation of the theoretical foundations of Venture financing and a review of the main theories developed on Venture investing. It includes a taxonomy of contracting clauses relevant in venture contracting, the conflicts they address, and presents some general observations on contractual clauses. Section 3 presents the research findings on the analysis of a European VC's deal flow and investment screening linked to the prevailing market conditions. Section 4 focuses an empirical study of a European VC's investment process, the criteria it uses to make its investments. It presents empirical findings on the investment criteria over time, business cycles, and investment types. It also links these criteria to the VC's subsequent performance. Finally, section 5 presents an empirical research on the comparison of the legal contracts signed between European and United States Venture Capitalists and the companies they finance. This research highlights some of the contracting practices in Europe and the United States.

Pain pattern and left internal mammary artery grafting.

BACKGROUND: This study was designed to determine whether the pain pattern in patients with an internal mammary artery (IMA) harvest differs from that in other cardiac operations and whether these patients present specific characteristics with clinical implications. METHODS: One hundred patients with left IMA grafting (IMA group) were compared prospectively with 100 patients who had a heart operation without IMA harvest (non-IMA group). Pain assessment was performed on postoperative days (POD) 1, 2, 3, and 7, and included pain intensity (10-point scale) and pain localization. RESULTS: In the IMA group, pain intensity was higher on POD 2 (4.2 +/- 2.4 versus 3.2 +/- 2.3, p < 0.01), and there were more patients without pain on POD 7 (32 versus 19, p = 0.03). In the IMA group, more patients had left basal thoracic pain throughout the entire study period and had sternal pain on POD 7, whereas more patients in the non-IMA group complained about back pain during the early postoperative period. CONCLUSIONS: The impact of IMA harvest on pain intensity is moderate, but the pain localization pattern of each group exhibits specific features that could help to better target pain management.

Internal arsenite bioassay calibration using multiple reporter cell lines

Bioassays with bioreporter bacteria are usually calibrated with analyte solutions of known concentrations that are analysed along with the samples of interest. This is done as bioreporter output (the intensity of light, fluorescence or colour) does not only depend on the target concentration, but also on the incubation time and physiological activity of the cells in the assay. Comparing the bioreporter output with standardized colour tables in the field seems rather difficult and error-prone. A new approach to control assay variations and improve application ease could be an internal calibration based on the use of multiple bioreporter cell lines with drastically different reporter protein outputs at a given analyte concentration. To test this concept, different Escherichia coli-based bioreporter strains expressing either cytochrome c peroxidase (CCP, or CCP mutants) or β-galactosidase upon induction with arsenite were constructed. The reporter strains differed either in the catalytic activity of the reporter protein (for CCP) or in the rates of reporter protein synthesis (for β-galactosidase), which, indeed, resulted in output signals with different intensities at the same arsenite concentration. Hence, it was possible to use combinations of these cell lines to define arsenite concentration ranges at which none, one or more cell lines gave qualitative (yes/no) visible signals that were relatively independent of incubation time or bioreporter activity. The discriminated concentration ranges would fit very well with the current permissive (e.g. World Health Organization) levels of arsenite in drinking water (10 µg l−1).

Acquisitions thérapeutiques en médecine ambulatoire en 2013 [2013 literature findings in internal general medicine].

The prescribing of antibiotics for uncomplicated skin abscesses and diverticulitis has no benefit. Some antibiotics are more at risk of causing a Clostridium difficile infection. The tests used to exclude a history of a penicillin allergy are safe. A threshold of D-dimer adjusted for the age significantly improves the specificity of the test without affecting the sensitivity. The prescription of paraclinics tests is not an effective "treatment" for the patient's anxiety. In the sleep apnea syndrome, treatment with CPAP (Continuous positive airway pressure) appears to have more benefits compared to the mandibular advancement prosthesis. The work of primary care physicians can be supported by the work of advanced practice nurses. The limitation placed on the working hours of doctors in hospitals seems to affect their ability to spend time with their patients.

Ultrastructural changes of the internal limiting membrane removed during indocyanine green assisted peeling versus conventional surgery for an idiopathic epimacular membrane

Purpose:To evaluate the histological features of cellular retinal fragments on the internal limiting membrane (ILM) removed during epiretinal membrane peeling surgery with and without the aid of ICG diluted in 5% glucose Methods:ILM specimens removed from 88 eyes undergoing vitrectomy and membrane peeling surgery for idiopathic epiretinal membrane between 1995 and 2003 were reviewed retrospectively. Surgery was performed in all cases by the same surgeon using the same technique. ICG was diluted with 5% glucose. Histological analysis focused on the presence and characteristics of retinal structures on the retinal surface of the ILM. Statistical analysis compared the results between group I (conventional surgery without ICG) and group II (ICG-assisted peeling) Results:Seventy-one eyes underwent EMM surgery without the aid of ICG (group I) and seventeen underwent EMM ICG-assisted surgery assisted using ICG (group II). The amount of Muller cell debris on the retinal surface of the ILM was more significant in the group I (no ICG) than in the group II (ICG) (40.8 versus 11.8; p = 0.024). Large fragments of Muller cells were more frequently observed in the group I (no ICG) than in the group II (ICG) (63.4% versus 23.5%; p= 0.003).The presence of larger retinal elements such as neural axons and vessels were observed attached to retinal face of the ILM in 5 (7%) cases of the no-ICG group. No such retinal elements were detected in any of the histological ILM specimens of the ICG-assisted group Conclusions:The use of ICG diluted with 5% glucose in the aid of ILM removal during epiretinal membrane surgery was associated with less retinal debris attached to retinal face of the ILM compared to surgery in which ICG was not used. Our findings contradict previous reports in the literature, in which use of ICG diluted with balanced salt solution (BSS) was associated with more retinal fragments attached to the retinal face of the ILM. According to our results, we hypothesize that diluting ICG with 5% glucose may decrease the adhesion of the ILM to the underlying retinal layers such that less retinal debris is removed with peeling of the ILM.
