Effect of Concurrent Lidocaine, Remifentanil and Methylprednisolone Use on the Clinical Effect of Sugammadex under General Anaesthesia in Rats.

Objective: In an study, lidocaine, remifentanil and methylprednisolone produced inclusion complexes with sugammadex, which lead to a decrease in free and active concentrations of sugammadex. When used concurrently with these drugs, it is likely that the time for sugammadex to reverse a neuromuscular blockade is going to be prolonged due to a synergistic pharmacokinetic or pharmacodynamic interaction. The aim of the present study was to investigate whether concurrent use of sugammadex with remifentanil, lidocaine and methylprednisolone led to a decrease in the neuromuscular blockade reversal effect of sugammadex produced with neuromuscular blockade agent (NMBA) rocuronium.

Novel BRCA2 pathogenic genotype and breast cancer phenotype discordance in monozygotic triplets.

BRCA1/2 genes with high-penetrance are tumor suppressor and tumor susceptibility genes that play important roles in the homologous recombination mechanism in DNA repair and increase breast cancer risk. Variants in BRCA1 or BRCA2 are the main causes of familial and early-onset breast cancer. This study investigated pathogenic variant belonging to the BRCA2 gene splice region in monozygotic triplets.
