PPF lowers temperatures throughout the entire kidney during RFA, most notably near the collecting system and is dependent on the temperature of the liquid used. In addition, PPF may cause less charring of the tissue around the probe resulting in lower resistance and higher power outputs.
"Broken heart" syndrome is a rare phenomenon characterized by transient ballooning of the left ventricle and chronic heart failure, usually presenting in postmenopausal women. It is formally known as acute stress-induced cardiomyopathy and, although described in the cardiology literature, it has not been previously described in plastic surgery patients. It is thought to occur secondary to increased catecholamine levels. This case report outlines two instances of the syndrome occurring in teenage girls undergoing cosmetic rhinoplasty.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
