Background: Breast implant surgery is one of the most frequently performed procedures by plastic surgeons worldwide. However, the relationship between silicone leakage and the most common complication, capsular contracture, is far from understood. This study aimed to compare Baker grade I with Baker grade IV capsules regarding their silicone content in an intradonor setting, using two previously validated imaging techniques.
Methods: Twenty-two donor-matched capsules from 11 patients experiencing unilateral complaints were included after bilateral explantation surgery. All capsules were examined using both stimulated Raman scattering (SRS) imaging and staining with modified oil red O (MORO). Evaluation was done visually for qualitative and semiquantitative assessment and automated for quantitative analysis.
Results: Using both SRS and MORO techniques, silicone was found in more Baker grade IV capsules (eight of 11 and 11 of 11, respectively) than in Baker grade I capsules (three of 11 and five of 11, respectively). Baker grade IV capsules also showed significantly more silicone content compared with the Baker grade I capsules. This was true for semiquantitative assessment for both SRS and MORO techniques ( P = 0.019 and P = 0.006, respectively), whereas quantitative analysis proved to be significant for MORO alone ( P = 0.026 versus P = 0.248 for SRS, respectively).
Conclusions: In this study, a significant correlation between capsule silicone content and capsular contracture is shown. An extensive and continued foreign body response to silicone particles is likely to be responsible. Considering the widespread use of silicone breast implants, these results affect many women worldwide and warrant a more focused research effort.

Limited utility of Epstein-Barr virus (EBV) surveillance for predicting post-transplant lymphoproliferative disorders in adult EBV seropositive lung transplant recipients.

Article Synopsis
- EBV DNAemia surveillance is used to prevent post-transplant lymphoproliferative disorder (PTLD) in lung transplant recipients (LTRs), but its effectiveness in adult seropositive patients is unclear.
- A study analyzed EBV viral loads in seropositive LTRs and compared levels between those who developed PTLD and those who didn't, revealing that peak viral loads were only significantly higher after PTLD was suspected.
- The study found low positive predictive values (PPVs) for moderate (14.7%) and high-grade (33.3%) EBV DNAemia in indicating risk for future PTLD, suggesting improved diagnostic approaches are needed.
Importance: Most patients with locally advanced hepatocellular carcinoma (HCC) recur within the liver following systemic therapy.
Objective: To determine whether stereotactic body radiation therapy (SBRT) improves outcomes in patients with locally advanced HCC compared with sorafenib alone.
Design, Setting, And Participants: This multicenter phase 3 randomized clinical trial randomized patients with HCC 1:1 to sorafenib or SBRT followed by sorafenib, stratified by performance status, liver function, degree of metastases, and macrovascular invasion.
Real-world Clinical Outcomes and Prognostic Factors in Neuroendocrine Prostate Cancer.
Clin Genitourin Cancer
November 2024
Tom Baker Cancer Centre, Calgary, Alberta, Canada.
Background: Neuroendocrine prostate cancer (NEPC) encompasses pure NEPC and tumors with mixed adenocarcinoma and neuroendocrine histology. While NEPC is thought to confer a poor prognosis, outcome data are sparse, making risk stratification and treatment decisions difficult for clinicians.
Methods: This retrospective study identified patients with morphological and/or immunohistochemical NEPC features on pathological review of high-grade prostate cancer cases.
Capsular Contracture After Breast Augmentation: Our Approach to Prevent Reoccurrence with Combined Total Capsulectomy and Implantation of Motiva Ergonomix® Implants.
Aesthetic Plast Surg
December 2024
VillaBella Clinic, Via Europa, 55, 25087, Salò, BS, Italy.
Background: Breast augmentation is the second most common aesthetic surgery worldwide. Capsular contracture, a prevalent complication which affects up to 30% of patients post-surgery, often leads to further necessary surgeries.
Objectives: This study investigates the effectiveness of total capsulectomy combined with Motiva Ergonomix® implant replacement in resolving capsular contracture and minimizing recurrence rates.
Use of 801 Acellular Dermal Matrices (ADMs) in Direct-to-Implant Breast Reconstruction: A Clinical Observation of Complication Profiles Over a 7-Year Period.
Aesthet Surg J

Article Synopsis
- The use of acellular dermal matrices (ADMs) like DermaCell in pre-pectoral breast reconstruction has shown benefits but comes with a noted increase in postoperative complications.
- A study evaluating 230 patients undergoing direct-to-implant breast reconstruction with DermaCell reported a 22.4% overall complication rate, with specific issues like rippling, skin ischemia, and capsular contraction.
- Despite the complications, patient satisfaction scores increased significantly, indicating that ADM can enhance the overall outcomes of breast reconstructive surgery.
