Perforation of viscera, a dramatic complication of liposuction: a review of 19 cases evaluated by experts in France between 2000 and 2012.

Background: Perforation of one or several intraperitoneal organs during a liposuction procedure is an exceptional but underestimated complication. Knowledge of this complication is essential because of frequent delay in diagnosis and possible dramatic consequences.

Methods: Nineteen cases were evaluated by experts and are presented in a retrospective analysis.

In vitro age-related responses of endothelial cells to breast cancer cell addition.

Aim: The purpose of this study was to determine if the in vitro age of endothelial cells alters endothelial response(s) to breast cancer cells.

Method: After characterizing lower passage ("young"; passages 10-16) and higher passage ("old"; passages 30-36) bovine pulmonary artery endothelial cells (BPAECs), fluorescently labeled MCF-7 breast cancer cells were added to confluent monolayers of young and old BPAECs.

Results: Transient gaps that peaked in size by 12 h and closed by 48h occurred between the young BPAECs, while large persistent gaps formed between the old BPAECs.
