en: Reduction of perioperative blood loss and operating time for arthroscopic rotator cuff repair by intravenous administration of tranexamic acid.

en: Administration of a single intravenous dose of TXA improved visual clarity in arthroscopic RCR, decreased the total operating time, and reduced hemoglobin loss on postoperative day 7.

ja: There were no statistically significant differences in the patient demographic data. The operating time was significantly shorter in the TXA group than in non-TXA group (97.8 ± 21.8 min vs 116.2 ± 26.0 min). The clarity of the visual field was similar between the two groups during the glenohumeral phase but was significantly higher in the TXA group during the resection of bursal tissue and acromioplasty and RCR phases. Hemoglobin level was not significantly different between the groups on postoperative day 1 but was significantly higher in the TXA group on day 7.

en: Blue light induces apoptosis and autophagy by promoting ROS-mediated mitochondrial dysfunction in synovial sarcoma.

en: Taken together, our results revealed that BL induced apoptosis via the ROS-mitochondrial signaling pathway, and autophagy was activated in response to the production of ROS, which protected SS cells from apoptosis. Therefore, BL is a promising candidate for the development of an antitumor therapeutic strategy targeting SS.

en: Partial thickness tear of the supraspinatus at the musculotendinous junction in a softball catcher.

en: We report a rare case of a partial thickness tear of the supraspinatus at the musculotendinous junction in a softball catcher. Preoperative magnetic resonance images of the shoulder showed high signal intensity areas at the musculotendinous junction, along with discontinuity of the articular side of the supraspinatus. Arthroscopic examination revealed articular-side partial tear at the musculotendinous junction. The patient was able to return to playing softball 20 weeks after arthroscopic side-to-side repair. J. Med. Invest. 68 : 386-388, August, 2021.
