Bacteremia is defined as the presence of bacteria in the blood. They can potentially lead to life-threatening septic shock.
Effective probabilistic antibiotic therapy must therefore be initiated immediately after blood cultures have been taken.
To diagnose bacteremia, blood culture bottles must first be incubated, which allows bacterial growth and early detection. Then, as soon as the sample is positive, an antibiogram of the incriminated bacterium is carried out by inoculation on MH (Mueller Hinton) medium. This diffusion antibiogram is the reference method and is obtained 24 hours after the vial is positive, i.e. around 48 hours after blood cultures are taken.
American recommendations agree that it is crucial to use rapid diagnostic tests to obtain the antibiogram. Antibiotic susceptibility test data can be used to broaden the spectrum of antibiotics in the event of ineffective therapy. They can also be used to reduce the spectrum of broad-spectrum antibiotics. This is part of the proper use of antibiotics and the reduction of multi-resistant bacteria (MRB) or highly resistant bacteria (HRB). Finally, it is also possible to carry out an early oral relay, thus avoiding intravenous infusions and their complications, and potentially reducing hospitalization times.
The investigators have evaluated a rapid antibiogram by diffusion on MHR-SIR (Mueller-Hinton Rapid-SIR) medium from the blood culture bottle. The investigators were able to obtain antibiogram results 7 hours after blood culture positivity, with excellent correlation compared with the standard method after 24 hours incubation on MH (Mueller-Hinton). The antibiotics tested were the same as with the standard method.
Secondly, The investigators were able to evaluate prospectively the impact of diffusion antibiotic susceptibility testing on MHR-SIR medium on early modification of antibiotic therapy in bacteremia, on 167 patients Antibiotic susceptibility test data on MHR-SIR enabled us to adapt antibiotic therapy 8 hours after blood culture positivity for 74 patients (44%). Antibiotic therapy was ineffective for 30 patients (18%) and was therefore extended. It also enabled us to reduce the spectrum of antibiotic therapy, in particular through early oral relay, for 44 patients (26%).
The aim of this multicenter trial is to validate on a large scale this strategy for obtaining rapid antibiotic susceptibility test results, with significant consequences in terms of optimizing antibiotic therapy.

From adulthood onwards, the aging process manifests itself in the spine through loss of disc height and kyphotic deformity. As the general population ages, the prevalence of lumbar degenerative diseases and sagittal imbalance increases. Sagittal balance is a physiological alignment resulting from the effective muscular and ligamentary forces that place patients' heads harmoniously in line with their pelvis. Roussouly first classified this alignment by differentiating four types of balance in an asymptomatic population. He established a link between the varieties of sagittal balance of the spine, the sacral slope and the position of the pelvis in space. He went on to explain sagittal imbalance in the aging population suffering from degenerative diseases.
One of the most common lumbar degenerative diseases is lumbar spinal canal stenosis. Stenosis of the lumbar spinal canal is frequently associated with sagittal imbalance of the spine. Lumbar canal stenosis causes lumbar pain, leg pain, neurogenic intermittent claudication and bladder and rectal disorders. The severity of clinical symptoms increases linearly with progressive sagittal imbalance [8]. We represent the sagittal imbalance of the spine by a positive sagittal vertical axis (SVA) presented by patients to reduce the pressure exerted by the yellow ligament, which is hypertrophied in degenerative disease . Many have shown that this forward-flexing posture can be improved by simple decompression, and that this deformity corresponds to an analgesic position and not to a structural deformity. Little is known about the factors that influence alignment after lumbar canal decompression and short segment fusion.
This study therefore aims to elucidate some of the clinical and radiological factors likely to affect postoperative sagittal balance in patients undergoing simple minimally invasive decompression surgery and short segment fusion (1 or 2 levels).

The aim of this prospective randomized controlled trial is to evaluate therapeutic hypnosis as a co-analgesia in thoracic drain removal in children with congenital heart disease. The hypothesis of this study is that therapeutic hypnosis combined with a minimal effective dose of medicated and inhaled sedation-analgesia is not inferior to higher doses of sedation-analgesia usually employed. This would make possible the reduction of cumulative dose of sedative medication and their side effects.
