Relation entre le taux de 1,25-dihydroxycholécalciférol et le pronostic fonctionnel après une fracture de hanche chez les personnes âgées

The present treatment of a fracture must allow an anatomical consolidation and an ad integrum functional recuperation. An osteosynthesis giving immediate stability allows for an early rehabilitation, articular and muscular. However, it modifies the biological and mechanical conditions of the spontaneous bony consolidation and determines limits to the physiotherapy according to the type of the fracture, the type of the osteosynthesis and the degree of evolution. A poor osteosynthesis and/or a maladjusted rehabilitation exposes a pathological consolidation.

Haemodynamic profile in paraphenylene-diamine poisoning

The accurate assessment and monitoring of arterial pressure is a key issue in the ICU. Arterial tonometry (applanation tonometry) is increasingly used in the cardiovascular field to noninvasively estimate pressure at the radial artery and carotid artery level and to reconstruct central aortic pressure. This allows the quantification of left ventricular afterload and may improve the evaluation of arterial stiffness and cardiovascular risk. The present article briefly summarizes the technical and methodological aspects of the technique and the potential interest in the rationale, pathophysiological management of ICU patients, with special focus on the links between pulse pressure and stroke volume.
