Good agreement between echocardiography and impedance cardiography in the assessment of left ventricular performance in hypertensive patients.

Background: Impedance cardiography (ICG) is a noninvasive hemodynamic monitoring tool which can define hypertensive patients' hemodynamic profiles and help to tailor antihypertensive therapy. This study assesses the concordance between ICG-derived indexes used to evaluate left ventricular performance and transthoracic echocardiography (TTE) in hypertensive patients.

Methods: In this IMPEDDANS post-hoc analysis, the ICG-derived indexes are compared with TTE by Bland-Altman method.

Multifocal septic arthritis, gluteal abscess and spondylodiscitis by subspecies after an intramuscular injection.

We present the case of a 63-year-old man, admitted for hand cellulitis and acute kidney injury. A subsp (SDSE) was isolated in blood cultures and despite directed intravenous antibiotherapy, the patient evolved unfavourably, with dorsolumbar spondylodiscitis, multifocal septic arthritis and abscesses. CT also showed densification of the gluteal muscles, multiple air bubbles in the psoas, paraspinal muscles and spinal canal that were associated with an intramuscular injection administered 1 week earlier for a backache.
