Inflammation is a local response to infection and tissue damage mediated by activated macrophages, monocytes, and other immune cells that release cytokines and other mediators of inflammation. For a long time, humoral and cellular mechanisms have been studied for their role in regulating the immune response, but recent advances in the field of immunology and neuroscience have also unraveled specific neural mechanisms with interesting therapeutic potential. The so-called cholinergic anti-inflammatory pathway (CAP) has been described to control innate immune responses and inflammation in a very potent manner...

Perineural adherences represent a problem after surgery involving peripheral neural system. Fat-grafting with adipose derived stem cells (ASCs) with their pro-regenerative characteristics can be important to prevent the neural damage or to facilitate the neural regeneration. Our idea was to use the fat-grafting as an anti-adherence device and test its efficacy on a postsurgical scar animal model and comparing to an antiadhesive gel. 32 athymic mice were operated under magnification, we exposed both sciatic nerves...

Laryngotracheal surgery has an inherent risk of injury to the recurrent laryngeal nerves (RLN). These complications go from minor dysphonia to even bilateral vocal cord paralysis. The intraoperative neuromonitoring of the RLN was developed in the field of thyroid surgery, in order to preserve nerve and vocal cord function. However, tracheal surgery requires in-field intubation of the distal trachea, which limits the use of nerve monitoring using conventional endotracheal tube with surface electrodes. Given these challenges, we present an alternative method for nerve monitoring during laryngotracheal surgery through the insertion of electrodes within the endolaryngeal musculature by bilateral puncture...
