The spine intra-abdominal pressure (SIAP) trial. A prospective, observational, single arm, monocenter study looking at the evolutions of the IAP prior, during and after spine surgery.

BACKGROUND AND AIMS: Both anaesthesiologists and spine surgeons consider the intra-abdominal pressure (IAP) as an important peri-operative factor affected by patient positioning. We assessed the change in IAP caused by using a thoraco pelvic support (inflatable prone support, IPS) with the subject under general anesthesia. The IAP was measured before, during and immediately after surgery. METHODS: The Spine Intra-Abdominal Pressure study (SIAP trial) is a prospective, single-arm, monocenter, observational study looking at changes in IAP prior, during and after spine surgery. The objective is to assess the change in IAP, measured via an indwelling urinary catheter, using the inflatable prone support (IPS) device during prone positioning of patients in spinal surgery. RESULTS: Forty (40) subjects requiring elective lumbar spine surgery in prone position were enrolled after providing informed consent. The inflation of the IPS results in a significant decrease of IAP (from a median of 9.2 mmHg to 6.46 mmHg (p < 0.001)) in patients undergoing spine surgery in prone position. This decrease in IAP was maintained throughout the procedure despite the discontinuation of muscle relaxants. No serious adverse events or unexpected adverse events occurred. CONCLUSION: The use of the thoraco-pelvic support IPS device was able to significantly lower the IAP during spine surgery.

Glia in Drosophila behavior.

Glial cells constitute about 10 % of the Drosophila nervous system. The development of genetic and molecular tools has helped greatly in defining different types of glia. Furthermore, considerable progress has been made in unraveling the mechanisms that control the development and differentiation of Drosophila glia. By contrast, the role of glia in adult Drosophila behavior is not well understood. We here summarize recent work describing the role of glia in normal behavior and in Drosophila models for neurological and behavioral disorders.

Treatment of the sacroiliac joint in patients with leg pain: a randomized-controlled trial.

PURPOSE: The sacroiliac joint (SIJ) may be a cause of sciatica. The aim of this study was to assess which treatment is successful for SIJ-related back and leg pain. METHODS: Using a single-blinded randomised trial, we assessed the short-term therapeutic efficacy of physiotherapy, manual therapy, and intra-articular injection with local corticosteroids in the SIJ in 51 patients with SIJ-related leg pain. The effect of the treatment was evaluated after 6 and 12 weeks. RESULTS: Of the 51 patients, 25 (56 %) were successfully treated. Physiotherapy was successful in 3 out of 15 patients (20 %), manual therapy in 13 of the 18 (72 %), and intra-articular injection in 9 of 18 (50 %) patients (p = 0.01). Manual therapy had a significantly better success rate than physiotherapy (p = 0.003). CONCLUSION: In this small single-blinded prospective study, manual therapy appeared to be the choice of treatment for patients with SIJ-related leg pain. A second choice of treatment to be considered is an intra-articular injection.
