Inducible limb-shaking transitory ischemic attacks:A video-documented case report and review of the literature
BACKGROUND: Limb-shaking transient ischemic attack (TIA) is a well-recognized, but rare observation in contralateral carotid steno-occlusive disease. Consequently, most clinicians have not had the chance to witness an attack. CASE PRESENTATION: We present the story of a 64-year old gentleman with exercise-induced weakness associated with tremor in his right arm. His left internal carotid artery was occluded at the bifurcation. Administration of statin and antiplatelet did not relieve his symptoms, and his stereotypic, exercise-induced âlimb-shakingâ episodes persisted. He underwent successful extracranial to intracranial (EC-IC) bypass, which stopped his symptoms. The patient, however, returned to our department and reported that he was able to recreate his original symptoms by compressing the bypass graft manually. CONCLUSION: To our knowledge, this is the first case with video documentation of the clinical appearance of a limb-shaking TIA. We hope this case report will increase the physiciansâ understanding of the clinical nature of limb-shaking TIAs.

Inducible limb-shaking transitory ischemic attacks: a video-documented case report and review of the literature
EMSL and Institute for Integrated Catalysis (IIC) Catalysis Workshop
Within the context of significantly accelerating scientific progress in research areas that address important societal problems, a workshop was held in November 2010 at EMSL to identify specific and topically important areas of research and capability needs in catalysis-related science
Resident and family perceptions of the nurse practitioner role in long term care settings: a qualitative descriptive study
BackgroundResearch evidence supports the positive impact on resident outcomes of nurse practitioners (NPs) working in long term care (LTC) homes. There are few studies that report the perceptions of residents and family members about the role of the NP in these settings. The purpose of this study was to explore the perceptions of residents and family members regarding the role of the NP in LTC homes.MethodsThe study applied a qualitative descriptive approach. In-depth individual and focus group interviews were conducted with 35 residents and family members from four LTC settings that employed a NP. Conventional content analysis was used to identify themes and sub-themes.ResultsTwo major themes were identified: NPs were seen as providing resident and family-centred care and as providing enhanced quality of care. NPs established caring relationships with residents and families, providing both informational and emotional support, as well as facilitating their participation in decision making. Residents and families perceived the NP as improving availability and timeliness of care and helping to prevent unnecessary hospitalization.ConclusionsThe perceptions of residents and family members of the NP role in LTC are consistent with the concepts of person-centred and relationship-centred care. The relationships NPs develop with residents and families are a central means through which enhanced quality of care occurs. Given the limited use of NPs in LTC settings, there is an opportunity for health care policy and decision makers to address service inadequacies through strategic deployment of NPs in LTC settings. NPs can use their expert knowledge and skill to assist residents and families to make informed choices regarding their health care and maintain a positive care experience

A new model of embolic stroke produced by photochemical injury to the carotid artery in the rat
We report a new model of embolic stroke in the rat, based on endothelial disruption and platelet aggregation in the carotid artery, which leads to distal embolization and focal brain infarction. The common carotid artery was irradiated for 6.5 minutes with the focused beam of an argon laser operated at a wavelength of 514.5 nm with a peak power of 2 W and an average power of 400 mw. Ipsilateral cerebral infarcts, ranging in size from 0.1 to 1.7 mm, were produced by platelet emboli in 12 of 13 rats. A total of 44 infarcts were observed in the 12 rats: 29 in the cortex, 6 in the hippocampus, 5 in the thalamus, and 4 in the basal ganglia. Scanning electron microscopy identified platelet aggregates in the carotid artery and in a deep cortical arteriole 50 minutes after the photochemical lesion. Twentyâfour hours after the experiment, scanning electron microscopy of the carotid artery revealed damaged endothelium but few remaining adherent platelets. More intense laser irradiation in 8 rats, leading to carotid occlusion, produced an infarct in only 1. This new model can be used to study the acute and chronic pathological changes in the brain associated with platelet embolism
Teaching about Sexual Harassment Issues: A Sales Management Approach
The major objective of a college is to prepare students for their future careers. One topic that is rarely addressed in the college classroom is sexual harassment, although students, particularly those in sales, may experience or be accused of sexual harassment in the corporate world. The authors provide guidance for the marketing instructor to introduce the topic of sexual harassment in the sales management classroom. They provide a variety of resources that enable the marketing instructor to discuss sexual harassment
