Article Abstract
Purpose: The aim of this study was to establish a more reliable method to predict pubic arch interference (PAI) before permanent prostate brachytherapy.
Material And Methods: We retrospectively analyzed the nuclear magnetic resonance imaging (MRI) results of forty patients with prostate cancer, who were treated with permanent implantation of I seeds (permanent brachytherapy). We measured and calculated six parameters based on the MRI results: 1. The prostate volume (PV); 2. The angle of the pubic arch (AoPA); 3. The angle of PAI (AoPAI, pubic symphysis level); 4. The height of PAI (hPAI, pubic symphysis level); 5. The maximum angle of PAI (AoPAI); 6. The maximum height of PAI (hPAI). We then tested which parameters could accurately predict PAI through receiver operating characteristic (ROC) curve analysis.
Results: The results of this study demonstrated that AoPAI, hPAI, hPAI, and AoPAI could predict PAI. Out of forty cases in our research, 10 cases were with PAI and 30 cases without PAI during the operation. The areas under the ROC curve for PV, AoPA, AoPAI (pubic symphysis level), hPAI (pubic symphysis level), AoPAI, and hPAI were 0.592, 0.567, 0.957, 0.940, 0.927, and 0.877, respectively. The AoPAI (pubic symphysis level), hPAI (pubic symphysis level), AoPAI, and hPAI were statistically correlated with PAI. The boundary values were 26.32°, 1.13 cm, 28.37°, and 1.51 cm, respectively.
Conclusions: This new method derived from MRI has predictive value, as AoPAI, hPAI, hPAI, and AoPAI could predict PAI. Taking other factors into consideration, we suggest the use of AoPAI as a novel and very reliable predictor of PAI.

To analyze CT angiographic images to provide comprehensive data on the corona mortis (CMOR) and propose a new classification method for venous corona mortis (VCMOR). This retrospective study included 719 patients (378 males, mean age 55 years) who underwent CT-enhanced examination of the whole abdomen or pelvis. Patient demographics, variation incidence, vessel diameter and location, anatomical configuration, and acetabular distance were evaluated.

Percutaneous fixation of the pubic symphysis is a relatively novel treatment strategy in the management of pelvic ring injuries with symphyseal disruption. While the current gold standard for surgical treatment of pubic symphysis diastasis is open reduction and plate fixation, high rates of implant failure and recurrent diastasis persist. Furthermore, blood loss, operative time, and postoperative infection associated with open approaches to the pelvis should be considered.

Introduction Delayed diagnosis of hip fracture (HF), one of the most common fractures encountered in clinical practice, is associated with serious complications or adverse outcomes. However, these fractures are frequently missed on radiography. Auscultatory percussion, a simple screening method that compares percussion sounds between lower limbs using a stethoscope, has limitations owing to its subjective evaluation, which can lead to unstable diagnostic accuracy.

Septic arthritis of the pubic symphysis is a rare but potentially life-threatening condition, particularly in the peripartum period. This case report details a 32-year-old woman in her first pregnancy, who developed severe pelvic pain, fever, and immobility following induction of labor at 41 weeks and 2 days of gestation. Initially diagnosed with chorioamnionitis, the patient underwent a caesarean section, but persistent groin pain and elevated inflammatory markers led to the discovery of septic arthritis of the pubic symphysis, confirmed by computed tomography and magnetic resonance imaging.

IEEE J Biomed Health Inform

During labor, transperineal ultrasound imaging can acquire real-time midsagittal images, through which the pubic symphysis and fetal head can be accurately identified, and the angle of progression (AoP) between them can be calculated, thereby quantitatively evaluating the descent and position of the fetal head in the birth canal in real time. However, current segmentation methods based on convolutional neural networks (CNNs) and Transformers generally depend heavily on large-scale manually annotated data, which limits their adoption in practical applications. In light of this limitation, this paper develops a new Transformer-based Semi-supervised Segmentation Network (TransSeg).
