Purpose: To identify factors associated with radiation exposure (RE) to operating room personnel during transperineal interstitial permanent prostate brachytherapy (TIPPB).
Methods And Materials: Between May 1998 and December 2000, 155 patients underwent TIPPB with fluoroscopic and ultrasound guidance. Data for each case included: operating room time (OT), anesthesia time (AT), fluoroscopy time (FT), number and type of seed implanted, total seed activity, and resident participation.
Results: Personnel RE per case, FT, OT, and AT decreased as case number increased. Whole body badge dose per case decreased from a mean of 0.15+/-0.01 mSv (15+/-1 mrem) in 1998 to 0.074+/-0.011 mSv (7+/-1 mrem) in 2000. Average FT per case decreased from a mean of 17:27 min (range, 10:40-28:23) in 1998 to 12:08 min (range, 6:40-31:00) in 2000. Resident participation was associated with increased FT. Mean whole body and ring badge doses for the treating radiation oncologist were 0.0076 mSv/min (0.76 mrem/min) and 0.05 mSv/min (5.26 mrem/min) of FT, respectively.
Conclusions: FT was the predominant factor that related to RE during TIPPB. Treating radiation oncologists were exposed to less than 20 mSv per 100 cases, significantly less than other fluoroscopically guided procedures. Nonetheless, appropriate radiation exposure precautions during TIPPB should continue.

UVB irradiation induces diverse modalities of regulatory cell death in keratinocytes. Recently, the pattern of coexistence of pyroptosis, apoptosis, and necroptosis has been termed PANoptosis; however, whether PANoptosis occurs in keratinocytes in UVB-induced skin injury remains unclear. We observed that the key molecules of GSDMD-mediated pyroptosis, apoptosis, and necroptosis, which are N-terminal GSDMD, cleaved caspase-3/PARP, and phosphorylated MLKL, respectively, were elevated in keratinocytes of UVB-challenged mice and human skin tissue.

Background: Cardiac catheterization via the trans-radial approach (TRA) has shown several advantages over the trans-femoral approach (TFA) but with a concern of higher radiation exposure. Considering the growing experience with TRA, this study compares patient's radiation during coronary angiography using TRA versus TFA.
Methods: This study included consecutive patients undergoing coronary angiogram over a year at tertiary hospital performed by experienced operators through radial or femoral access.

Purpose: To review patients with recurrent patellar dislocation surgically treated with robot-assisted medial patellofemoral ligament (MPFL) reconstruction compared with patients who underwent surgery using the traditional freehand technique.
Methods: A retrospective cohort study was performed to identify patients who underwent MPFL reconstruction from January 2020 to December 2023 in our hospital. The inclusion criteria were: patients aged from 15 to 50 years; patellar dislocation occurred two or more times; a Merchant view or computed tomography (CT) scan indicating patellofemoral joint malalignment, external patellar inclination, or lateral patellar dislocation; underwent MPFL reconstruction via robot-assisted or traditional freehand technique; complete medical records and imaging data before and after surgery; a minimum of 1 year of postoperative follow-up.
