Hypoglycémie et traitement du diabète de type 2. Le retour à une normoglycémie n'est pas nécessairement la meilleure stratégie thérapeutique [Hypoglycemia and diabetes treatment: the return to normal glucose level is not always the best therapeutic strategy].

Recent clinical trials with type 2 diabetic patients and the quest of normal glyceamic values, have revealed difficulties and limitations. These too normal glyceamic targets corresponding to the physiological standards are associated with very high rate of hypoglycemia and an increase of mortality. A too simplistic view of treatment: "the lowest, the better is in the diabetes" is no longer defensible. The knowledge from complex systems behavior invites us to search targets adapted to a new state of equilibrium due to loss of self-regulation. These targets should not aim the physiological standards but to be adapted to patient's situation. Shared decision-making and consensus are the two pillars of this new strategy supported by the new ADA-EASD guidelines.

Traitement chirurgical de la diplopie secondaire à l'orbitopathie dysthyroïdienne [Surgical treatment of diplopia in Graves' orbitopathy]

BACKGROUND: The correction of oculomotor disorder in Grave's disease is applied on pathological extraocular muscles. Based on the global muscular restriction (bilateral forced duction test) and angular measurements, we have used a non-adjustable technique. PATIENTS AND METHODS: We performed a retrospective analysis of 21 patients (23 operations) with thyroid-associated orbitopathy operated for persisting diplopia. The angles of deviation in the 9 diagnostic directions of gaze and the field of binocular vision were measured with the Harm's tangent scale before and after surgery. Sixteen patients were operated only on vertical muscles. The mean follow-up was 45 months. RESULTS: 76 % of the patients (95 % confidence interval [CI], 58-94 %) obtained a large and centred field of binocular vision without prisms. 14 % (95 % CI, 0-29 %) had binocular vision with the use of prisms. Diplopia persisted in one patient despite 3 operations. Taking into consideration the interventions done before the patient was referred to us, the reintervention rate was 13 % (95 % CI, 0-28 %). CONCLUSIONS: A binocular field of vision can be successfully restored in the majority of patients with Graves' orbitopathy, using a non-adjustable surgical technique.

Traitement des tumeurs malignes du foie par radiologie interventionnelle: techniques ablatives [Interventional radiology procedures for malignancies of the liver: ablation procedures].

Percutaneous ablative procedures allow curative treatment of stage BCLC 0 or BCLC A hepatocellular carcinoma, as well as liver metastases of colorectal cancer. Several methods exist including radiofrequency ablation, the most commonly used. These techniques can be used in combination with surgical excision or alone if surgery is contraindicated. They are associated with significantly reduced mortality as compared to surgery.

Traitement nutritionnel du grand brûlé [Nutritional therapy in major burns]

Résumé Les brûlures graves (> 20 % surface corporelle [SC]) entraînent un stress oxydatif intense, des perturbations métaboliques et une réponse inflammatoire caractérisées par leur intensité et par leur durée, sans comparaison avec celles observées dans les autres pathologies. La modulation de ces réponses est devenue un objectif thérapeutique. Le brûlé nécessite des apports élevés en énergie (35-50 kcal/kg par jour), en glucides et en protéines (1,5-2,5 g/kg par jour) et faibles en lipides (idéalement moins de 20 % de l'apport calorique). La supplémentation en glutamine contribue à normaliser la réponse immunitaire et accélère la cicatrisation. La voie entérale (gastrique ou postpylorique) est la voie de choix et doit être utilisée dès le jour de l'accident. Les déficits aigus et précoces de micronutriments sont causés par des pertes exudatives par la peau lésée : la substitution est bénéfique sur le plan biologique et clinique. Les doses nécessaires sont de l'ordre de cinq à dix fois celles utilisées dans d'autres indications de nutrition parentérale pendant sept à 30 jours selon la SC brûlée. L'insuline qui favorise l'anabolisme et le propranolol qui réduit le catabolisme font partie de l'arsenal thérapeutique standard. Le suivi nutritionnel (poids et préalbumine hebdomadaire) est essentiel pour vérifier la réponse au support nutritionnel.

Consultation d'urgence/crise pour couples et families: motifs d'urgence et évaluation du traitement [Couples and families emergency/crisis consultation: emergency patterns and treatment assessment]

Since the opening in 2003 of the Couple & Family Consultation Unit (UCCF) at Prangins Hospital, we have met urgent demands and observed that the suffering systems (i.e., couples and families) couldn't face any waiting period. So in 2007 an Emergency/Crisis Facility was created, based on the hypothesis that there is no contra-indication to systemic emergency care, if one understands and structures both crisis and treatment. We studied the suffering population in demand and the emergency/crisis issues and assessed therapy efficiency. Then we observed that treating suffering systems in emergency does produce therapeutic gain in terms of crisis resolution and patients' satisfaction. Those treatments refer to public health issues, as considered the human, social and financial cost of couples/families dysfunctions.
