Idiopathic premature ventricular complexes originating from the ventricular outflow tract: evaluation, prognosis and management The prognosis of ventricular premature complexes (VPC) in the absence of heart disease is considered benign. VPC usually originate from the right or, less commonly, left ventricular outflow tract. QRS complexes therefore usually assume a left bundle branch block and inferior axis morphology. These VPC, particularly if very frequent (> 20,000 per day), may adversely affect left ventricular function and their suppression can restore normal function. Moreover, there is a clinical overlap with arrhythmogenic right ventricular dysplasia and this diagnosis should be considered when facing a left bundle branch block shaped VPC. However, the prognosis of outflow tract VPC is good for appropriately selected patients with normal left ventricular function, absence of syncope or ventricular tachycardia, and no evidence of cardiac disease.

The widespread use of abdominal imaging technologies has led to an increase in the incidental finding of liver tumors. Most of these lesions are asymptomatic and will not require any treatment. With the use of contrast-enhanced radiological studies, most of the tumors can be reliably diagnosed by non-invasive means. In case of diagnostic uncertainty, patients should not undergo percutaneous biopsy but rather complete resection of the lesion for an unequivocal diagnosis. Such pathologies must be taken charge of in centers with expertise by interdisciplinary teams.

Diagnostic and treatment management of prostate cancer at its initial stage continues to raise important debates within the involved medical community. To establish a protocol for active surveillance, a validated option in specific conditions of localised prostate cancer management for eight years, is a unique opportunity to gather different specialists in this field. This paper presents this concept.

Objectif : La prise en charge des patients avec hyperglycémie en soins aigus estdifficile et les erreurs de prescription d'insuline sont fréquentes. Notre objectifest de promouvoir l'évolution des pratiques vers une gestion efficace et sécuritairede l'hyperglycémie.Matériels et méthodes : Création d'un programme de formation structuré pourla gestion de l'hyperglycémie en soins aigus. Ce programme est le produit dumétissage entre le modèle de l'accompagnement thérapeutique et la systémiquedu management. Il vise l'acquisition d'une métacognition pour une réflexiontransversale face à l'hyperglycémie. Les objectifs spécifiques sont : comprendreles particularités de l'hyperglycémie en aigu ; gérer le basal/bolus ; argumenterle choix thérapeutique ; s'approprier l'outil sécuritaire d'aide à l'insulinothérapie ;anticiper la sortie du patient. Une analyse mixte a été effectuée : quantitative,glycémies, hypoglycémies, durée de séjour et qualitative, évolution de la réflexionautour de l'hyperglycémie.Résultats : Nov. 2009-2010, dans le Service de Médecine du CHUV, nous avonsdispensé 3 sessions de formation (15 cours), suivies d'une période de coaching,pour 78 internes. Évaluation quantitative : 85 patients (56,4 % H), âge moyen72,7 ± 9,6 ans, glycémies à J3 dans la cible (4-8,5 mmol/l) 44,6 %, glycémiemoyenne 8,5 ± 1,8 mmol/l, hypoglycémies 0,9 %, durée moyenne de séjour9,7 ± 5,4 J. Évaluation qualitative : choix du schéma thérapeutique pertinentdans la majorité des cas, environ 90 % des internes ont intégré les éléments depondération de l'insulinothérapie, estiment que cette formation a eu un impactpositif sur leur gestion, sont plus confiants dans leurs capacités et ont unmeilleur sentiment d'auto-efficacité. Les modalités pédagogiques adoptées ontfavorisé le transfert des compétences et le niveau de satisfaction globale atteint90 %.Conclusion : Le développement d'un programme de formation des soignants,basé sur l'approche réflexive et participative, permet une amélioration importantede la gestion de l'hyperglycémie. Notre projet s'inscrit dans une démarcheglobale visant à doter les bénéficiaires d'une vision systémique du diabète.

In the last 15 years, the therapeutical options for the treatment of chronic inflammatory diseases in rheumatology have increased a lot. Nevertheless, some patients do not respond or respond partially to the current therapies--including to the biologics therapy. Tofacitinib (Xeljanz) is now on the Swiss market. It inhibits the JAK pathway. Tofacitinib--as monotherapy or with methotrexate--improves the control of rheumatoid arthritis (RA). In a comparative study, tofacitinib was as effective as adalimumab. Further, tofacitinib reduced structural damages in RA and is considered as an alternative, in case of non-response, to anti-TNF and probably to other biologics therapy. The side effects are upper respiratory tract and opportunist infections and tuberculosis. Blood count, lipids, kidney function, liver tests, CK and blood pressure have to be monitored.

Acute exacerbation of COPD is one of the most common causes of hospital admission in patients affected with this disease. In most cases, consideration of differential diagnoses and assessment of important comorbidities will allow to make the decision whether or not the patient needs to be hospitalized. A decision to hospitalize will be based on specific symptoms and signs, as well on the patient's history. Contrary to bronchial asthma, a systematic action plan strategy is lacking for COPD. However, a disease management plan involving all the health care providers may have the potential to improve the patient's well being and to decrease costs related to these exacerbations.
