improvement in phonation after reconstruction of the recurrent laryngeal nerve in patients with thyroid cancer invading the nerve
Surgery, 2009Co-Authors: Akira Miyauchi, Hiroyasu Inoue, Chisato Tomoda, Mitsuhiro Fukushima, Minoru Kihara, Takuya Higashiyama, Yuuki Takamura, Yasuhiro Ito, Kaoru Kobayashi, Akihiro MiyaAbstract:Background We report vocal improvement after reconstruction of the recurrent laryngeal nerve (RLN) in patients with nerve resection, although vocal cord movement was not restored. These methods are not widely recognized. Methods Direct anastomosis, free nerve grafting, or anastomosis to the ansa cervicalis or the vagus nerves with the RLN were performed in 7, 14, 65, and 2 patients with thyroid cancer invading the RLN, respectively. A total of 51 patients had vocal cord paralysis (VCP) pre-operatively. Maximum phonation time (MPT) and vital capacity (VC) were measured before and 1 year after reconstruction. A total of 34 normal subjects and 27 patients with VCP served as controls. Results Patients with VCP had significantly shorter MPT values than normal subjects. At 1 year after operation, patients with reconstruction had values of MPT similar to those of normal subjects. Men had significantly longer MPT values than women, but the phonation Efficiency Index (PEI), defined as the MPT/VC ratio, did not differ by sex. The PEI was significantly less in VCP patients than in normal subjects. Patients with reconstruction achieved PEI values similar to those in normal subjects. Phonation Efficiency Index values at 1 year after operation was significantly greater than pre-operative PEI and was not affected by the presence or absence of VCP pre-operatively, age, reconstruction method, thickness of suture thread, or use of magnification during the operation. Conclusion In patients with thyroid cancer requiring RLN resection, RLN reconstruction achieved recovery in phonatory function.

an agent based test bed study of wholesale power market performance measures
IEEE Computational Intelligence Magazine, 2008Co-Authors: Abhishek Somani, Leigh TesfatsionAbstract:Wholesale power markets operating over transmission grids subject to congestion have distinctive features that complicate the detection of market power and operational inEfficiency. This study uses a "wholesale power market test bed "with strategically learning traders to experimentally test the extent to "which market performance measures commonly used for other industries are informative for the dynamic operation of restructured "wholesale power markets. Examined measures include the Herfindahl-Hirschman Index (HHI), the Lerner Index (LI), the residual supply Index (RSI), the relative market advantage Index (RMAI), and the operational Efficiency Index (OEI).
