[Effectiveness of analgesic techniques after breast surgery: a meta-analysis]. / Efficacité des techniques d'analgésie locorégionale après chirurgie du sein: une méta-analyse.

OBJECTIVE: To evaluate the effectiveness of locoregional analgesic techniques (thoracic paravertebral block (TPVB), wound infiltration (WI)) after breast surgery. STUDY DESIGN: Meta-analysis. METHODS: Searches of Medline and Cochrane were performed using the search terms "breast surgery" and "local anaesthetics" and "infiltration" or "paravertebral block". Manual searches were also performed. Two independent investigators assessed the publications and extracted the data. Inclusion criteria were randomised controlled trials that evaluated effectiveness of single-injection TPVB or WI with local anaesthetics after breast surgery. Postoperative pain scores evaluated by visual analogic scale (VAS) during the first six hours (H6), at twelve hours (H12) and incidence of postoperative nausea and vomiting (PONV) were collected. RESULTS: Nine studies met inclusion criteria with five trials that evaluated paravertebral block (N=253) and 4 studies that evaluated wound infiltration (N=174). TPVB decreased significantly VAS at H6 (Weighted mean difference (WMD)=-18 [-5;-32] ; P=0.007) and at H12 (WMD=-12[-20;-4] ; P=0.001) and the risk of PONV (relative risk=0.39 [0.26; 0.57] ; P<0.00001). WI did not decrease significantly VAS for postoperative pain and PONV. CONCLUSION: Single injection TPVB in contrast to WI is effective for analgesia after breast surgery and decreases PONV.

[Allergic reaction to patent blue dye for sentinel lymph node detection during uterus oncological surgery]. / Réaction allergique après injection de bleu patenté pour le repérage du ganglion sentinelle au cours de la chirurgie carcinologique utérine.

Patent blue V dye is used to localize the sentinel lymph node during breast and uterine oncological surgery. The case of a grade III anaphylactic reaction related to patent blue dye paracervical injection is described in a 34-year-old woman scheduled for hysterectomy. This complication needs to be rapidly diagnosed to apply adapted supportive treatment.

[Cholestatic hepatitis induced by the amoxicillin-clavulanic acid combination. A case and review of the literature]. / Hépatite cholestatique due à l'association amoxicilline-acide clavulanique. Un cas et revue de la littérature.

We report the case of a patient who developed jaundice after receiving amoxicillin-clavulanic acid for 7 days. Laboratory features were consistent with acute cholestatic hepatitis. Histopathological examination of a liver specimen showed cholestasis. Complete recovery occurred within 2 months after withdrawal of the drug. Analysis of the 24 reported cases of amoxicillin-clavulanic acid induced hepatitis revealed a predominantly cholestatic syndrome occurring soon after drug administration. In all cases, hepatic dysfunction disappeared within 1 to 3 months after discontinuation of the drug. Because of the small number of cases in contrast with the widespread use of this drug, associated with blood hypereosinophilia or eosinophilic infiltration of portal triads in some cases, a hypersensitivity phenomenon is suggested.

[The locked-in syndrome]. / Le syndrome de verrouillage.

The locked-in syndrome is poorly understood, and may be misdiagnosed as coma. The syndrome consists of complete paralysis of all four limbs and the lower cranial nerve pairs, associated with an unaltered consciousness. Vertical eye movements and blinking remain intact, so allowing some form of communication by way of eye codes. Obstruction of the vertebral and basilar vascular system is the major cause, but the six cases reported show the aetiological diversity of this syndrome. If the vascular obstruction is diagnosed within the first few hours, fibrinolytic therapy may be considered. Although the patients usually die within a few days or after several months, some rare cases of recovery after several weeks have been reported. Intensive care is required by these patients (tracheostomy, artificial ventilation, intensive nursing care); the physicians and nursing staff looking after them should always keep in mind that these patients are conscious and able to communicate.
