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.

Determinants of the development of post-traumatic stress disorder, in the general population.

PURPOSE: To assess (1) the lifetime prevalence of exposure both to trauma and post-traumatic stress disorder (PTSD); (2) the risk of PTSD by type of trauma; and (3) the determinants of the development of PTSD in the community. METHODS: The Diagnostic Interview for Genetic Studies was administered to a random sample of an urban area (N = 3,691). RESULTS: (1) The lifetime prevalence estimates of exposure to trauma and PTSD were 21.0 and 5.0%; respectively, with a twice as high prevalence of PTSD in women compared to men despite a similar likelihood of exposure in the two sexes; (2) Sexual abuse was the trauma involving the highest risk of PTSD; (3) The risk of PTSD was most strongly associated with sexual abuse followed by preexisting bipolar disorder, alcohol dependence, antisocial personality, childhood separation anxiety disorder, being victim of crime, witnessing violence, Neuroticism and Problem-focused coping strategies. After adjustment for these characteristics, female sex was no longer found to be significantly associated with the risk of PTSD. CONCLUSIONS: The risk for the development of PTSD after exposure to traumatic events is associated with several factors including the type of exposure, preexisting psychopathology, personality features and coping strategies which independently contribute to the vulnerability to PTSD.

Les maladies inflarnmatoires chroniques de l'intestin: "survival kit" pour internistes et généralistes [Inflammatory bowel disease: a "survival kit" for general practitioners]

There are approximately 12000 patients suffering from inflammatory bowel disease (IBD) in Switzerland. IBD can be debilitating not only because of the direct consequences in the gut but also because of extraintestinal manifestations. An early diagnosis is the key in defining optimal therapeutic interventions. The management is multidisciplinary and the general practitioner should work in direct collaboration with a gastroenterologist. Optimal management should aim at inducing and maintaining remission as well as reducing the risk of complications such as abcesses, fistulas or colorectal cancer.

La lombalgie aiguë en médecine de premier recours [Acute low back pain in general practice medicine].

The practioner's first concern is knowing how to single out from the immense majority of situations susceptible to a favourable spontaneous evolution those patients with a bad prognostic necessitating reference to a specialist. We present in this paper the clinical steps designed to meet this challenge and a reminder of certain principles of patient diagnosis and care.

Multisensory Integration: Flexible Use of General Operations.

Research into the anatomical substrates and "principles" for integrating inputs from separate sensory surfaces has yielded divergent findings. This suggests that multisensory integration is flexible and context dependent and underlines the need for dynamically adaptive neuronal integration mechanisms. We propose that flexible multisensory integration can be explained by a combination of canonical, population-level integrative operations, such as oscillatory phase resetting and divisive normalization. These canonical operations subsume multisensory integration into a fundamental set of principles as to how the brain integrates all sorts of information, and they are being used proactively and adaptively. We illustrate this proposition by unifying recent findings from different research themes such as timing, behavioral goal, and experience-related differences in integration.
