Background/purpose: The purpose of this study was to investigate the influence of different located post surgical scars on both perfusion and redness. The pattern of change and correlation between perfusion and redness of post surgical scars is also examined.
Methods: In this study, we measured redness and perfusion of the abdominal and breast scar of 24 women undergoing breast reconstruction with Deep Inferior Epigastric Perforator Free Flap surgery with the Minolta Chromameter CR-400/410 and the Moor Instruments laser Doppler imager 12IR, respectively, at different intervals post-operatively.
Results: The laser Doppler imager gives significantly higher values for the abdominal compared with the breast scar. There was no consistent correlation found between perfusion and redness at the different test moments for both locations. The scores of both parameters were significantly associated after 9 months follow-up for both locations.
Conclusion: Scars closed with higher mechanical force show higher perfusion and prolonged activity; and more redness is associated with more perfusion for both post surgical scars. Nevertheless, there was no consistent correlation found between these parameters making the laser Doppler imager and the Colorimeter still non-replaceable instruments.

Aim: Computed tomography (CT)-derived extracellular volume fraction (ECV) is a non-invasive method to quantify myocardial fibrosis. Evaluating CT-ECV during aortic valve replacement (AVR) planning CT in severe aortic stenosis (AS) may aid prognostic stratification. This meta-analysis evaluated the prognostic significance of CT-ECV in severe AS necessitating AVR.

Department of Orthopedic Surgery, Mayo Clinic, Rochester, MN.
Background: Vertebral body tethering (VBT) is a nonfusion surgical treatment for scoliosis. Recent data have shown that intraoperative correction is critical for successful curve correction over time. This study aims to evaluate the relationship between preoperative, intraoperative, and postoperative correction.

Ophthalmology Clinic, Department of Biomedical Sciences, University of Messina, Italy.
Purpose: This literature review synthetizes current evidence on the timing and efficacy of dexamethasone intravitreal injections for diabetic macular edema (DME) in patients undergoing cataract surgery, particularly phacoemulsification, to determine the optimal timing for improved outcome.
Methods: A systematic review of the literature was conducted across key databases to identify peer-reviewed studies, clinical trials, and meta-analyses addressing dexamethasone injections administered pre-, intra-, and post-operatively for DME in the context of cataract surgery. Studies were selected based on relevance to timing, visual outcomes, and inflammation control, with a focus on comparative efficacy.
Risk of cancer and reoperation after ileorectal anastomosis and ileal pouch-anal anastomosis in familial adenomatous polyposis.

Department of Gastroenterology and Hepatology, Amsterdam UMC, University of Amsterdam, Amsterdam, the Netherlands.
Objectives: To prevent colorectal cancer (CRC), most patients with familial adenomatous polyposis (FAP) undergo (procto)colectomy with ileorectal anastomosis (IRA) or ileal pouch-anal anastomosis (IPAA). After surgery, these patients remain at risk of developing cancer in the remnant rectum or rectal cuff/pouch. We aimed to compare the long-term risk of cancer following IRA or IPAA in FAP.
