Cryptococcus infection presenting as a spinal cord syndrome has been reported, but all of these cases were vertebral osteomyelitis. We report on an immunocompetent 49-year-old man with(More)
OBJECTIVE To identify and evaluate factors associated with delayed recognition of pulmonary tuberculosis (TB) in the emergency department (ED). BACKGROUND Delayed recognition of pulmonary TB in ED may precipitate mortality and morbidity. METHODS Medical records of newly diagnosed TB patients admitted to four hospitals in Taiwan were retrospectively(More)
Tumor cells transduced with herpes simplex virus thymidine kinase gene has been intensively applied to the field of positron emission tomography via imaging of its substrate. As a pilot synthesis approach, a facial preparation of 5-[125I]iodoarabinosyl uridine starting from commercial available uridine is reported herein. Interestingly, the tin group in(More)
As scaling down MOSFET devices degrade device performance in term of leakage current and short channel effects. To overcome the problem a newer device Silicon-on-Insulator (SOI) MOSFET has been introduced. The Fully Depleted (FD) SOI MOSFETs also suffer from short channel effects (SCE) in the sub 65 nm regime due to reduction in threshold voltage. Several(More)

BACKGROUND Headaches are one of the most common afflictions in adults and reasons for emergency department (ED) visits. OBJECTIVE We sought to determine the association between physician risk tolerance and head computed tomography (CT) use in patients with headaches in the ED. METHODS We performed a retrospective study of patients with nontraumatic(More)
