Conditioning magnetic stimulation of the cerebellum suppresses the motor cortex 5–8 ms later, probably through activation of cerebellar Purkinje cells, which inhibit the dentatothalamocortical pathway. To further characterize this pathway, we examined several factors that may modulate its excitability. We tested the effects of different test motor evoked(More)
OBJECTIVE Lesioning or stimulation of the cerebellar thalamus is an established treatment for rest and postural tremors in Parkinson disease (PD). The cerebellothalamocortical (CTC) pathway can be assessed by transcranial magnetic stimulation (TMS) of the cerebellum, which suppresses the contralateral primary motor cortex (M1), a phenomenon termed(More)
INTRODUCTION The decentralization of HIV services has been shown to improve equity in access to care for the rural poor of sub-Saharan Africa. This study aims to contribute to our understanding of the impact of decentralization on costs borne by patients. Such information is valuable for economic evaluations of anti-retroviral therapy programmes that take a(More)
The cerebellum is implicated in the pathogenesis of essential tremor (ET). The authors examined the excitability of the cerebellothalamocortical pathway in ET and found it to be normal. Tremor reset occurred with motor cortex stimulation but not with cerebellar stimulation. These findings suggest that the abnormal oscillatory activity in ET does not(More)
As a result of increased interest in global health, more and more medical students and trainees from the 'developed world' are working and studying in the 'developing world'. However, while opportunities to do this important work increase, there has been insufficient development of ethical guidelines for students. It is often assumed that ethics training in(More)
Injuries due to small arms and light weapons (SALW) are common in developing countries with ongoing collective violence, or those that exist in a post-conflict state. Uganda has a long history of armed conflict, but little quantitative evidence is available about the extent of the problem of SALW. We performed a review of all injuries due to SALW at Mbale(More)
We investigated small arms and light weapons (SALW) in Africa by reviewing the situation in Nigeria and conducting a small study in one hospital in the country's north. Published reports about SALW in Nigeria suggest that several social, economic, and political factors have caused a marked increase in gun-related violence, including ethno-religious(More)
BACKGROUND Using the knowledge-to-action (KTA) process, this study examined barriers to use of evidence-based interventions to improve early detection of cancer among South Asians from the perspective of multiple stakeholders. METHODS In 2011, we used concept mapping with South Asian residents, and representatives from health service and community service(More)
INTRODUCTION As high out-of-pocket healthcare expenses pose heavy financial burden on the families, Government of India is considering a variety of financing and delivery options to universalize health care services. Hence, an estimate of the cost of delivering universal health care services is needed. METHODS We developed a model to estimate recurrent(More)
INTRODUCTION Promoting health equity is a key goal of many public health systems. However, little is known about how equity is conceptualized in such systems, particularly as standards of public health practice are established. As part of a larger study examining the renewal of public health in two Canadian provinces, Ontario and British Columbia (BC), we(More)
