Review Randomized Controlled Trial Comparative Study
Tolerance of local anesthetic for transrectal ultrasound-guided prostate biopsy: our experience and a literature review.
To determine whether local anesthetic injection or gel reduced pain during transrectal ultrasound-guided prostate biopsies and whether there was significant difference between quadrant and apex-only anesthesia. ⋯ There was significant pain reduction with local anesthetic injections but not with gel, and since there was no significant difference in efficacy between quadrant and apex-only injections, we recommend apex-only local anesthetic injections for transrectal ultrasound--guided prostate biopsies because it simplifies the injection procedure.

With the resurgence of pulmonary tuberculosis and musculoskeletal tuberculosis in North America and Europe over the last 20 years, the typical pattern of extraspinal musculoskeletal tuberculosis has been changing; presentation of the disease often mimics that of neoplasia. However, certain radiographic features may offer some clues to the more benign nature of the process and its inflammatory and infectious nature. Although the diagnosis of extraspinal musculoskeletal tuberculosis depends largely on clinical context, it is the radiologist's role to guide the imaging workup to initiate the specific treatment as early as possible. ⋯ This review considers atypical osteoarticular tuberculosis and tuberculous osteomyelitis. We discuss examples of these atypical presentations. All patients were permanent residents in Europe and North America, and all were immunocompetent.

To estimate the diagnostic reference levels and effective radiation dose to patients from routine computed tomography (CT) examinations in the province of British Columbia, Canada. ⋯ Among hospitals, there was considerable variation in the DLP and patient radiation dose for a specific exam. Reference doses and patient doses were higher than those found in similar recent surveys carried out in the United Kingdom and the European Union. Patient doses were similar to those found in a recent survey in Germany.

Comparative Study
Percutaneous vertebroplasty in patients with intractable pain from osteoporotic or metastatic fractures: A prospective study using quality-of-life assessment.
Percutaneous vertebroplasty (PVP) is a minimally invasive outpatient procedure whereby vertebral compression fractures are stabilized by the injection of bone cement, or polymethyl methacrylate (PMMA). Rapid partial or complete pain relief can usually be achieved through this procedure. We prospectively evaluate the efficacy of PVP in the relief of pain and improvement in quality of life of patients with intractable pain from osteoporotic and metastatic fractures. ⋯ PVP in osteoporotic and metastatic fractures significantly improved many patients' global quality-of-life scores and function by markedly decreasing their back pain and reducing their intake of pain medications. The procedure is safe, with no serious complications noted in our study.

Comparative Study
Canadian radiology residents' knowledge of sedation and analgesia: a web-based survey.
An increasing number of procedures in the radiology department require the use of conscious sedation, with the agents often administered by the radiologist. We sought to determine the level of understanding of the nature and use of such agents in Canadian radiology residents. ⋯ Despite the recent publication of conscious sedation guidelines for nonanesthesiologists, this survey suggests that Canadian radiology residents are not receiving adequate training in the use of medications required for conscious sedation.
