3-Dimensional Wiring Allows for ARCADIA Technique Followed by Rotational Atherectomy for Calcified Nodules.

Background: The aggressive wire recanalization in calcified atheroma and dilation technique is performed to treat eccentric calcified lesions in the peripheral arteries.

Case Summary: We present a clinical case in which this technique was successfully applied to treat an eccentric calcified nodule (CN) in the right coronary artery.

Discussion: CN is an independent predictor of poor clinical outcomes after percutaneous coronary intervention.

Activated eosinophil plays a role in promoting fibrosis in endometriotic lesion.

The fibrosis mechanism in endometriosis is not elucidated. We investigated the role of eosinophil in fibrosis of endometriosis. The endometriotic stromal cells (ESCs) and endometrial epithelial cells (EECs) were subjected to in vitro experiments.

Rotablator Burr Disconnection and a Gap Predictor.

Disconnection of the rotational atherectomy (Rotablator) burr during rotational atherectomy is an extremely rare complication, the precise etiology of which remains unclear. At our institution, we have encountered 6 cases of burr disconnection over a period of 16 years. The target vessels were the right coronary artery in 4 cases and the left circumflex artery in the remaining 2 cases.

Uterine angle changes during the in vitro fertilization treatment cycle.

Studies have focused on uterine peristalsis and endometrial development, whereas knowledge is limited on cyclical changes in the uterocervical angle (the angle formed between the uterine corpus and cervix) during the menstrual cycle. Here, these dynamic changes were investigated. We conducted a retrospective analysis of 99 freeze-thawed blastocyst transfer cycles in 2020 and a prospective analysis of 192 cycles between 2022 and 2023.

The effectiveness of an oral gonadotropin-releasing hormone antagonist relugolix for retained products of conception (RPOC) formed after abortion at less than 22 weeks of gestation: a retrospective study.

Purpose: This study investigated the effectiveness of an oral GnRH antagonist for retained products of conception (RPOC) carrying a risk of heavy bleeding.

Methods: With IRB approval and patient consent, this retrospective study included 97 RPOC cases after miscarriage. Clinical courses of the GnRH antagonist group ( = 20) were compared with those of non-GnRH antagonist group (historical control, = 77).

First Attempt of Tip Detection-Antegrade Dissection and Re-Entry Using Conventional Intravascular Ultrasound in Coronary Intervention.

This study developed a tip detection (TD) method and chronic total occlusion (CTO)-specific short-tip intravascular ultrasound (IVUS) with a pullback transducer system. We devised TD-antegrade dissection reentry and standardized CTO wiring. This CTO-specific IVUS is not available outside Japan.

Comparison between tip-detection method and retrograde approach for chronic total occlusion percutaneous coronary intervention.

Background: The tip-detection method and the retrograde approach have been acknowledged as a second-line strategies for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) when conventional antegrade wiring strategies are ineffective. The aim of this study is to compare the efficacy between both strategies for complex CTO PCI.

Methods: We retrospectively enrolled 170 consecutive CTO PCI cases and separated them into 295 adopted strategies.

Exertional Lower Extremity Pain in a Triathlete Caused by External Iliac Artery Endofibrosis: A Case Report.

Case: This report describes a 25-year-old female professional triathlete with right external iliac artery endofibrosis (EIAE) that was definitively diagnosed on contrast-enhanced magnetic resonance images obtained immediately after treadmill running. The EIAE was treated by percutaneous transluminal angioplasty. By 8 weeks after surgery, she had no symptoms of claudication or pain in the right thigh after a 1-hour running session.

Chronological changes in the rate of surgical field contamination in the shoulder joint.

Background: In shoulder surgery, low-virulence bacteria such as Cutibacterium acnes and coagulase-negative staphylococci can cause postoperative infection. However, the degree of sterility during surgery after disinfection is not known, and the efficacy of double skin preparation for such bacteria is unclear. This study aimed to evaluate chronological changes in the surgical field contamination rate in the shoulder joint and to compare single and double skin preparation.

Primary synovial chondromatosis of the shoulder followed for 11 years after arthroscopic surgery: A case report.

We report a case of primary synovial chondromatosis of the shoulder (Milgram classification, stage III) in a 25-year-old woman. She underwent arthroscopic removal of multiple loose bodies and partial synovectomy. Histological findings revealed primary synovial chondromatosis.

Endometrioid Carcinoma of the Uterine Corpus With a Micropapillary Component: A Novel Prognostic Factor For Metastasis.

Background/aim: Micropapillary pattern is a morphologically distinctive form of carcinoma composed of small, hollow, or morula-like clusters of cancer cells surrounded by clear stromal spaces. The neoplastic cells characteristically display a reverse polarity, also known as an ''inside-out'' growth pattern, that is linked to higher frequencies of lymphovascular invasion and lymph nodal metastasis. To the best of our knowledge, it has not been previously recognized in uterine corpus.

Affecting Factors of Prostate Volume in Forensic Autopsied Decedents.

Because decedents undergoing forensic autopsies would have behaved normally before death, prostate volume according to age group can be confirmed with forensic autopsy materials. The objectives of this study were to first confirm the current prostate volume by age and then determine diseases that can influence prostate volume using forensic autopsy materials. Prostate specimens were collected from forensic autopsies performed at Shiga University of Medical Science, Japan, between January 2015 and December 2019.

Quadratus lumborum muscle strain in a youth soccer player: a case report.

We report a case of quadratus lumborum muscle strain that occurred in a 16-year-old soccer player during a game. According to a video recording of the game, the injury occurred when the leg landed just after kicking the ball with the same leg while dribbling. The mechanism was suspected to be right lateral flexion of the trunk while the pelvis was simultaneously forced to tilt backward.

Hysteroscopic resection with temporary balloon catheter occlusion of bilateral internal iliac arteries for managing retained products of conception after spontaneous abortion: Two cases report.

Retained products of conception (RPOC) is a condition in which trophoblastic tissue remains in the uterus after pregnancy, causing massive hemorrhage in some cases. Though RPOC is commonly treated by intrauterine curettage or hysteroscopic resection uterine artery embolization or hysterectomy may be performed in case of massive bleeding. We experienced two cases of RPOC after surgery for missed abortion that failed to respond to conservative treatment and required surgical treatment.

Mirror-image streptavidin with specific binding to L-biotin, the unnatural enantiomer.

The streptavidin-biotin system is known to have a very high affinity and specificity and is widely used in biochemical immunoassays and diagnostics. However, this method is affected by endogenous D-biotin in serum sample measurements (biotin interference). While several efforts using alternative high-affinity binding systems (e.
