Induction of Phlorotannins and Gene Expression in the Brown Macroalga in Response to the Herbivore .

Mechanisms related to the induction of phlorotannin biosynthesis in marine brown algae remain poorly known. Several studies undertaken on fucoid species have shown that phlorotannins accumulate in the algae for several days or weeks after being exposed to grazing, and this is measured by direct quantification of soluble phenolic compounds. In order to investigate earlier inducible responses involved in phlorotannin metabolism, was studied between 6 and 72 h of grazing by the sea snail .

Persistent neuropathic pain after inguinal herniorrhaphy depending on the procedure (open mesh v. laparoscopy): a propensity-matched analysis.

Background: A greater incidence of persistent pain after inguinal herniorrhaphy is suspected with the open mesh procedure than with laparoscopy (transabdominal preperitoneal), but the involvement of neuropathy needs to be clarified.

Methods: We examined the cumulative incidence of neuropathic persistent pain, defined as self-report of pain at the surgical site with neuropathic aspects, within 6 months after surgery in 2 prospective subcohorts of a multicentre study. We compared open mesh with laparoscopy using different analysis, including a propensity-matched analysis with the propensity score built from a multivariable analysis using a generalized linear model.

[Validation of the French version of the non-communicating children's pain checklist - postoperative version].

Purpose: The aim of the study was to test the validity of a French language version of the Non-Communicating Children's Pain Checklist - Postoperative Version (NCCPC-PV): grille d'évaluation de la douleur-déficience intellectuelle (GED-DI).

Methods: We assessed the intensity of pain in 87 intellectually disabled surgical patients recruited in four Canadian and French hospitals in the pre- and post-operative settings using the GED-DI, a 100-mm visual analogue pain scale (VAS) and the Rosen sedation scale. The validity of the GED-DI was measured by the difference in scores between pre- and postoperative conditions.

A prospective study of neuropathic pain induced by thoracotomy: incidence, clinical description, and diagnosis.

This study evaluated prospectively the incidence of neuropathic pain after thoracotomy, described its clinical characteristics, and delineated landmarks for its diagnosis in daily practice. We evaluated clinically painful symptoms and sensory deficits in 54 patients after lateral/posterolateral thoracotomy for broncho-pulmonary carcinoma with standardized surgical and analgesic procedures. At 2months, 49 patients suffered from non malignant thoracic pain, and at 6months 38 patients (loss to follow-up for 7) reported persisting pain.

Perioperative ketamine does not prevent chronic pain after thoracotomy.

Thoracotomy is often responsible for chronic pain, possibly of neuropathic origin. To confirm preclinical studies, the preventive effects of perioperative ketamine were tested in a randomized, double-blind, placebo-controlled clinical trial on persistent neuropathic pain after thoracotomy. Eighty-six patients scheduled for thoracotomy under standardised general anaesthesia were randomised to receive either ketamine (1 mg kg(-1) at the induction, 1 mg kg(-1) h(-1) during surgery, then 1 mg kg(-1) during 24 h; n=42) or normal saline (n=44).
