14. Predictors of pain during phacoemulsification under local sedation: A multicentric study

Author

Debourdeau, E., Ortis, F., Chamard, C., Crowdy, H., Jeanjean, L., Audemard, D., Payerols, A., Villain, M., De Jong, A., and Daien, V.

Abstract

•Cataract surgery is the most frequently performed surgery in the world, yet few studies have investigated predictors of associated pain.•The significant risk factors for pain during phacoemulsification are IOL power<19 D, chronic analgesic use, white/brown cataract, iris complications, surgery time≥20min, and blood pressure increase.•A larger study may help develop a predictive score for pain that could, for example, be integrated into a biometer.

Abstract

PURPOSE We have previously presented evidence that the neutrophil chemoattractant, N-acetyl-proline-glycine-proline (N-acetyl-PGP), triggers the initial polymorphonuclear leukocyte (PMN) invasion into the alkali-injured eye. In this study, sense-antisense methodology was used to develop novel complementary peptides to be potential inhibitors of N-acetyl-PGP. METHODS The polarization assay was used to measure the potential chemotactic response of PMNs to synthetic N-acetyl-PGP, the ultrafiltered tripeptide chemoattractants obtained from alkali-degraded rabbit corneas, or leukotriene B4 (LTB4). Inhibition was expressed as the peptide concentration producing 50% inhibition (ID50) of polarization. Five complementary peptides were tested as potential inhibitors of N-acetyl-PGP: arginine-threonine-arginine (RTR), RTR-glycine-glycine (RTRGG), RTR dimer, RTR tetramer, and alanine-serine-alanine (ASA) tetramer. In addition, the RTR tetramer and both monomeric peptides (RTR and RTRGG) were separately tested for inhibition of the ultrafiltered tripeptide chemoattractants or LTB4. RESULTS The complementary RTR tetrameric peptide was a powerful antagonist of N-acetyl-PGP-induced PMN polarization (ID50 of 200 nM). The RTR dimer was much less potent (ID50 of 105 microM). Both monomeric peptides, RTR and RTRGG, were only antagonistic at millimolar concentrations. The ASA tetramer showed no capacity to inhibit N-acetyl-PGP. The RTR tetramer also inhibited PMN activation by the ultrafiltered tripeptide chemoattractants (ID50 of 30 microM) but had no effect on LTB4. CONCLUSIONS A complementary peptide (RTR) was designed which is an effective inhibitor of the neutrophil chemoattractant, N-acetyl-PGP. The potency of the RTR complementary peptide is dramatically enhanced by tetramerization. Inhibition of N-acetyl-PGP by complementary peptides offers great promise for control of the inflammatory response in the alkali-injured eye.

Abstract

Dans le traitement des anevrismes situes au niveau de la partie cervicale haute de l'ACI, la technique de pontage cervico-petreux par greffon veineux “in situ” (telescopage du greffon veineux dans l'ACI) peut etre une alternative aux pontages cervico-petreux extra-anatomiques (avec passage sous-cutane du greffon veineux), en ayant les avantages d'un pontage anatomique sans necessite d'une resection extensive de la base du crâne pour positionner en continuite le greffon veineux.
