Incontinence urinaire chez la femme: prise en charge en médecine de premier recours [Urinary incontinence in women: management in primary care]

Urinary incontinence in women is a largely under-evaluated problem that affects nearly one out of two adult women. Even thouh its physiopathology is complex and its etiologies are multiple (and often intricate), urodynamic investigations are not considered necessary before starting a conservative therapy, which can be initiated by the primary care physician. Conservative management is based upon lifestyle modifications, specialized physiotherapy, and in certain cases medication. In the case of insufficient response after three months, the patient should be recommended to a specialist who can evaluate the need for a surgical procedure.

Diagnostic et prise en charge de la thrombocytopénie immune primaire

La thrombocytopénie immune primaire (ITP) est une affection auto-immune acquise avec diminution de la survie des plaquettes et perturbation de la production plaquettaire. Il n'existe aucun test clinique simple permettant de prouver la nature auto-immune de l'affection. Pour cette raison, il s'agit presque toujours d'un diagnostic par exclusion d'autres causes. Bien que les plaquettes soient souvent inférieures à 10 x 109/l lors de la présentation initiale, la tendance hémorragique est étonnamment modérée chez la majorité des patients. Le traitement initial fait toujours appel aux corticostéroïdes, combinés à des immunoglobulines intraveineuses et à des transfusions de plaquettes dans les formes compliquées avec hémorragies significatives. Chez l'enfant, la maladie est souvent induite par des infections virales et son évolution est bénigne et spontanément régressive dans la majorité des cas. Chez l'adulte, la maladie est plus souvent persistante ou chroniquement récidivante, et le taux de plaquettes se situe souvent à un taux suffisant pour prévenir des hémorragies spontanées. Seule une faible proportion de patients souffre d'une thrombocytopénie sévère prolongée accompagnée de saignements réguliers avec risque d'hémorragies potentiellement fatales. C'est probablement ce groupe de patients restreint qui tirera surtout profit des nouvelles options thérapeutiques telles que les agonistes du récepteur de la thrombopoïétine. A la lumière de ces nouvelles possibilités, un groupe d'hématologues suisses s'est réuni pour élaborer des directives concernant la prise en charge de l'ITP conformément aux besoins et aux habitudes de notre pays.

Analyse des épisodes de bactériémies chez les patients nécessitant une prise en charge aux soins intensifs

Introduction : Bacteremia are among the leading forms of severe infections requiring ICU management, and have been reported to be associated with important morbidity and mortality. Bloodstream infection (BSI) can be classified as hospital-acquired (HA), healthcare-associated (HCA) and community-acquired (CA). Each type has its own characteristics and outcome. Methods : We analyzed all consecutive episodes of bacteremia occurring in patients hospitalized in our mixed 32-bed ICU over a 12 month period (01.10.2009-30.09.2010). HA BSI were prospectively included in a multicenter study (EUROBACT). We adapted the case report form to analyze retrospectively all other cases of BSI. Chi-square tests were used for the categorical variables and ANOVA tests for the continuous variables. Results : Bacteremia occurred in 103 patients (120 bacteria) for an incidence-density of 49.3 episodes/1000 admissions. Among HA episodes, about one quarter of episodes was related to vascular accesses, including two thirds acquired outside of the ICU. Concerning HCA BSI, two-thirds originated from the urinary tract. In contrast, a respiratory origin was found in one third of CA episodes. Multiresistant microorganisms were more frequent in HA and HCA BSI. The overall mortality was 32%, as compared to 7.9% and 13.6% for the overall ICU and hospital mortality of other ICU patients over the same period, respectively. In a multivariate model, age (1.06 [1.02-1.11]), septic shock (3.11 [1.16-8.33]) and renal remplacement (7.81 [1.50, 14.93]) were significantly associated with a fatal outcome. Conclusion : Two-thirds of bacteremia documented among ICU patients were nosocomial and in contrast to those community-acquired, Gram-negatives represented the majority of them. However, CA bacteremia were associated with a higher rate of septic shock and death. The microbiological characteristics of HCA episodes were more similar to those HA, that is why it is important to individualize this category in order to adapt the antibiotics.

Mise en place d'un cathéter veineux central chez l'adulte. 2. Technique détaillée [The central vein catheterization. 2. Procedure, step by step]

La pose d'un cathéter veineux central peut se faire par plusieurs abords. La connaissance de l'anatomie, du matériel, la maîtrise des détails de la procédure pour chaque type d'abord et une attention particulière à l'asepsie sont des prérequis importants pour limiter les risques de complications et pour donner une information complète et exhaustive au patient. Cet article peut être utilisé comme base pour le développement d'une check-list, utile pour les médecins qui doivent procéder à la pose d'un cathéter veineux central mais qui ne possèdent pas encore une maîtrise du geste. Several approaches exist for central vein catheterization. Mastery of the various steps of this procedure and understanding of the basics of asepsis are critical to prevent any complication. They also built the basis for an exhaustive communication with the patient, to obtain an informed consent. This article can in addition be used to develop a checklist in order to (self-)assess competence in procedural skills

Recommandations pour la prise en charge de la forme systémique l'arthrite juvénile idiopathique (maladie de Still) [Guidelines for diagnosis and treatment in systemic-onset juvenile idiopathic arthritis.]

A guideline group of pediatric rheumatologist experts elaborated guidelines related to the management of idiopathic juvenile arthritis in association with the Haute Autorité de Santé (HAS). A systematic search of the literature published between 1998 and August 2008 and indexed in Pubmed was undertaken. Here, we present the guidelines for diagnosis and treatment in systemic-onset juvenile idiopathic arthritis.

Principes d'evaluation et de prise en charge des patients agés polymorbides: guide a l'intention des cliniciens [Principles for the assessment and management of polymorbid elderly patients: a guide for clinicians].

Providing care to multimorbid older patients is complex, not only because of the coexistence of multiple chronic conditions, but also because of their frequent intrication with psychological and social problems. This article describes a guide for clinicians to assess and manage multimorbid older patients. This guide was adapted from the work of a group of expert US geriatricians. It proposes seven steps: identification of the main problem; identification of patients' preferences; setting of goals of care; estimation of life expectancy; identification of relevant evidence in the literature; revision of the plan of care; and discussion of the options with the patient. The use of this guide is illustrated by a clinical case.

Paralysie faciale: diagnostic et prise en charge [Diagnosis and management of facial paralysis]

Facial palsy is an unusual pathology that requires standard investigations and management. A clinical overview of the current attitudes is suggested to the general practitioners in order to help them in initiating the adequate investigations and treatment before referring the patient to a specialist.

Hypertension portale et prise en charge de l'ascite [Management of ascites due to portal hypertension].

Portal hypertension is regularly encountered by the general practitioner. It is defined by an elevation of the porto-systemic pressure gradient, with complications such as ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, variceal bleeding, hypersplenism, hepatopulmonary syndrome or hepatic encephalopathy occuring when a significant elevation of this gradient is reached. Cirrhosis is the primary cause of portal hypertension in industrialized countries. Symptomatic portal hypertension carries a poor prognosis. Management should be initiated rapidly, including the identification and correction of any reversible underlying condition. Liver transplantation should be considered in advanced cases.

Adhésion thérapeutique du patient chronique: des concepts a la prise en charge ambulatoire [Medication adherence in chronic patients: from its concepts to its management in primary care].

Medication nonadherence is common and its determinants are diverse. Adherence is influenced by many parameters, such as patient's self-efficacy, knowledge of health risk, outcome expectations, benefits of change, and barriers and facilitators. The sociocognitive theory helps professionals to structure their approach and to support patients in managing their treatment. Professionals need skills and time, and benefit from coordination in care, in particular between physicians and pharmacists. This article presents the key elements of a medication adherence program as well as tools and some useful questions.

Allergie aux venins d'hyménopteres: nouveautés diagnostiques et prise en charge [Hymenoptera venom allergy: new diagnostic tools and management].

Anaphylactic reactions to hymenoptera venoms are common and, in our latitudes, mainly concern wasps and bees. Recently, molecular biology techniques have contributed to identifying and to sequencing the major allergens of insect venoms and led to the production of recombinant allergens. Assays for specific IgE directed against these recombinant allergens have recently been made available in clinical practice. They provide considerable assistance in identifying the insect responsible for an anaphylactic reaction, in particular when standard tests are positive for both wasp and bee. This article focuses on these new laboratory tests and also reviews the management of patients experiencing an anaphylactic reaction after hymenoptera sting.
