“Introduction:\n\nSubthalamic nucleus deep brain stimulation has become a useful tool in effectively treating severe Parkinson’s disease.\n\nMethod:\n\nWhile most reports in literature describe the immediate and short-term post-operative brain lead implant-related adverse check details events, we present the case of a 65-year-old man who developed herpes zoster (HZ) upon the subcutaneous placement of the pulse generator two years after the procedure.\n\nConclusion:\n\nHe had excellent recovery of HZ lesions and related pain after specific antiviral therapy. The importance of a correct diagnosis of this unusual complication

is outlined in order to minimize the risk of debilitating chronic HZ-associated pain.”
“A magnetically levitated impeller within a pediatric ventricular assist device operates under highly transient flow conditions. In this study, computational

analyses were performed to investigate the hydraulic performance and fluid forces on the impeller under the steady and dynamic flow conditions, including: 1) time-varying boundary conditions (TVBC) considering a pulsed pump flow rate and pulsed left ventricular pressure; 2) transient rotational sliding interfaces Selleckchem SB203580 (TRSI) to capture virtual blade rotation. Under steady flow conditions, the pressure generation for 0.5-6 I/min over 6000-10000 rpm was 20-140 mmHg; experimental validation agreed to within 6-27%. Under transient flow selleck chemical conditions, the outflow pressure of the pump increased with higher inlet pressure during the TVBC simulation. During TVBC, the pressure rise across the pump decreased as a function of higher flow rates and increased as a function of lower flow rates. The radial fluid forces varied directly with the flow rate by demonstrating larger forces at higher flow rates. For TRSI simulations, pressure fluctuations

due the blade passage frequency were found to have 12 peaks per revolution, having magnitude ranges of 0.7 and 1.0 mmHg for 8 000 and 10 000 rpm, respectively. At 8 000 rpm, the fluid forces ranged from 1.15-1.17 N (axial) and 0.02-0.11 N (radial). Transient simulations model implant scenarios more realistically and provide critical information about the fluid conditions in the pump.”
“A taxonomic review of the Atheta Thomson subgenus Microdota Mulsant & Rey in Korea is presented. The subgenus is represented in Korea by 15 species including two new species, Atheta (Microdota) jangtaesanensis Lee & Ahn, sp. n. and A. (M.) pasniki Lee & Ahn, sp. n. Four species [A. (M.) kawachiensis Cameron, A. (M.) muris Sawada, A. (M.) spiniventris Bernhauer, and A. (M.) spinula (Sawada)] are new to the Korean Peninsula and two [A. (M.) formicetorum Bernhauer and A. (M.) subcrenulata Bernhauer] to South Korea. Two other species [A. (M.) kobensis Cameron and A. (M.) scrobicollis (Kraatz)] previously recorded in North Korea had been identified incorrectly.
