Background Multiple penetration depths of high-intensity focused ultrasound (HIFU) treatment for facial rejuvenation have not been quantified. Methods We enrolled 12 participants (n=24) to undergo one session of HIFU rejuvenation between January 1, 2019, and January 10, 2020. We used a 2-, 4.5-, and 6-mm focal depth transducer on the upper and middle face. We evaluated efficacy on days 60 and 90 by using our specific assessment system. Results The average eyebrow peak and pupil–eyebrow peak angles significantly increased by 2° (p < 0.0005) and decreased by 1° (p < 0.0001), respectively, at day 90. The shortened eyebrow–iris length indicated that the forehead tissues had lifted and moved medially to the central face. Supraorbital tissues were also vertically elevated, marked by the eyebrow–orbital (p = 0.0016) and vertical palpebral fissure lengths (p = 0.0052), which both exhibited a 0.8-cm elevation. For the midface, the increased canthus–oral–nasal angle (p = 0.5881) and decreased tragus–oral length (p = 0.5881) indicated that laxity had been corrected through lifted oral commissure, though the data were not statistically significant. No serious side effects were observed. Conclusion HIFU treatment with multiple depths quantitatively improved both upper-facial rejuvenation and midface rejuvenation after a single session.

Context: In Changhua Christian Hospital (CCH), the urology division is a branch of the surgical department. The urology residents in this division are, on average, off duty for 10 days/month; surgical residents from other divisions usually lack training to practice urology. Therefore, attending urology doctors or visiting urology staff members in CCH branches must be on call during off-duty periods in case a patient is indicated for suprapubic cystostomy. Aims: This study aims to promote a safe and efficient approach to train rotating residents to perform suprapubic catheterization. Subjects and Methods: On the basis of ultrasound-guided central venous catheter insertion, we designed training sessions for suprapubic cystostomy for rotating surgical residents during their urology course. Participants and Methods: From 2016 to 2018, senior residents or attending doctors of urology evaluated the clinical skills of rotating residents by using the direct observation of procedural skills tool before and after the training course. Statistical Analysis Used: Mann–Whitney U-test, Wilcoxon signed rank test, and multiple linear regression analysis. Results: The trainees were separated into different groups according to their sex, year of residency, and previous urology training in the postgraduate year (PGY). All groups had significant gain scores. Our multiple linear regression analysis revealed a relationship between previous urology training in the PGY and gain scores and between overall pretest score and gain scores. Conclusions: Real-time ultrasound-guided catheterization with a Seldinger wire is a safe and efficient approach to train rotating residents to perform suprapubic catheterization.
