Four cases of cauda equina syndrome occurring after continuous spinal anesthesia are reported. In all four cases, there was evidence of a focal sensory block and, to achieve adequate analgesia, a dose of local anesthetic was given that was greater than that usually administered with a single-injection technique. We postulate that the combination of maldistribution and a relatively high dose of ...

Maldistribution of health professionals between urban and rural areas has been a serious problem in China. Urban hospitals attract most of the health professionals with serious shortages in rural areas. To address this issue, a number of policies have been implemented by the government, such as free medical education in exchange for obligatory rural service.

The United States Congress has recently passed an important bill entitled, The Health Professionals Assistance Act of 1976. It seeks to right physician maldistribution in the country and curtail the over specialization of medical practitioners. Quotas have been set in terms of the number of medical school graduates who must enter primary care training programs over the next few years. Failure t...

Geographic fatty liver is sometimes revealed on computed tomography (CT) images. In patients with this condition, perivascular fat deposition characterized by halos of fat surrounding the hepatic and/or portal vein develops; however, the pathogenesis remains unknown (1, 2). A 30-year-old man developed severe alcoholic hepatitis. Initial abdominal CT revealed homogeneous fatty liver with mild ma...

This work assesses the possibility/feasibility of utilizing CFD to predict water-air separation in a mini-manifold at ambient conditions. The manifold consists header with three reduced T-junctions. A combination size and operating parameters yields computationally demanding surface tension dominant flow. computational model is based on interface tracking technique FVM framework. results are va...
