AIM: to investigate physicians' knowledge including chronic hepatitis B(CHB) diagnosis, screening, and management in various stages of their ***: A voluntary 20-question survey was administered in Santa Clara County, CA where Asian and Pacific Islanders(API) account for a third of the population. Among the 219 physician participants,there were 63 interns, 60 second-year residents, 26 chief residents and 70 attending physicians. the survey asked questions regarding respondents' demographics,general hepatitis B virus knowledge questions(i.e.,transmission, prevalence, diagnostic testing, prevention,and treatment options), as well as, self-reported practice behavior and confidence in ***: Knowledge about screening and managing patients with CHB was poor: only 24% identified the correct tests to screen for CHB, 13% knew the next steps for patients testing positive for CHB, 18% knew the high prevalence rate among API, and 31% knew how to screen for liver cancer. Wald chi-square analysis determined the effect of training level on knowledge; in all cases except for knowledge of liver cancer screening(p = 0.0032), knowledge did not significantly increase with length in residency training or completion of ***: Even in a high-risk region, both medical school and residency training have not adequatelyprepared physicians in the screening and management of CHB.

Potential Use of Ultrasonic Cavitation threshold to Non-Invasively Differentiate Cystic Masses

引用

Open Journal of Radiology 2014年第4期4卷 329-338页

Objectives: to demonstrate in vitro that.changes in ultrasound cavitation threshold might be used for non-invasively distinguishing high viscosity mucinous fluid from low viscosity serous fluid in cystic masses, based on the facts that cavitation threshold increases with increasing viscosity and that cavitation microbubbles are observable with diagnostic ultrasound. Methods: An in vitro model of a cyst was designed using dilutions of ultrasonic gel, and the cavitation threshold of this model was determined using focused and unfocused ultrasound for bubble initiation and clinical ultrasound b-scan for detection. Results: Viscosities of dilutions between 0% and 30% gel were had viscosities measuring between 1.05 ± 0.08 cP and 6600 ± 875 cP. Inertial cavitation in the latter was determined to require an order of magnitude greater intensity, at 1 MHz and 100% duty cycle, than the former (>2.2 W/cm2 vs. trasound. A four-fold increase in the peak negative pressure was required to initiate significant bubble activity using 1.1 MHz and 50% duty cycle focused ultrasound in the 6600 cP fluid compared with the 1 cP fluid. Based on these results, it was estimated that a threshold could be defined that would result in no bubbles in 99.9% of mucinous cysts and just 22% of serous cysts. the remaining 78% of patients presenting with serous cysts would be positively identified by detection of bubbles, and would be spared an unnecessary biopsy. Conclusions: the cavitation threshold may be used non-invasively to distinguish between high viscosity and low viscosity fluids in cysts and reduce biopsies on serous cysts.
