Background: The incidence of methicillin-resistant Staphylococcus aureus (MRSA) carriers and infections continues to rise. Some specialties have demonstrated a reduction in infection through appropriate screening and treatment.
Objectives: We sought to investigate the incidence of preoperative colonization, postoperative conversion, and whether this had any impact on outcomes in patients undergoing post-mastectomy breast reconstruction (BR).
Methods: This is a prospective study of a series of 122 BR patients from a single surgeon from May 2013 to March 2015. Nasal swabs were obtained at preoperative and postoperative clinic visits. The incidence of preoperative and postoperative colonization, demographic, and clinical variables were analyzed and compared to complication rates within 90 days of surgery.
Results: The incidence of MRSA colonization was 3.3% (n = 4) preoperatively and 4.1% (n = 5) postoperatively. One patient was positive at both time points, and 4 patients converted postoperatively. Preoperative or postoperative colonization with MRSA was not associated with any specific patient demographics. Hospital length of stay tended to be longer in patients colonized both preoperatively (2.8 days vs 1.6 days, P = .075) and postoperatively (2.8 days vs 1.8 days, P = .072). Postoperative colonization trended toward an increased incidence of any complication (80.0% vs 35.7%, P = .068) and was significantly associated with delayed wound healing (40.0% vs 4.8%, P = .035). Having a minor complication (P = .073) and implant exposure (P = .056) tended to be associated with postoperative carriers.
Conclusions: The incidence of MRSA in breast reconstruction patients is relatively low, yet complications rates are higher in those patients. Multicenter randomized trials should be conducted to determine if there is a role for preoperative screening and treatment of MRSA carriers.
Level Of Evidence: 2 Risk.

January 2025
Department of Plastic and Reconstructive Surgery, Royal Free NHS Foundation Trust, London, United Kingdom.
Background: There has been a delayed, yet steady uptake of robotic-assisted surgery over the past decade within the field of plastic surgery. In an era of rapidly evolving scientific and technological development, there is a need for an update on the current literature for robotic-assisted plastic surgery procedures.
Methods: Searches were conducted across major databases, including MEDLINE, Embase, and Central for published literature from March 2023 to December 2024.
Chest wall perforator flap reconstruction in breast conserving surgery: quality of life and limited complications in outpatient treatment.

Background: Breast conserving surgery (BCS) with partial breast reconstruction (PBR) results in less morbidity, better cosmetic outcomes, and improved patient satisfaction compared to mastectomy. Perforator flap reconstruction can attenuate defects prone to breast deformity after BCS. Usually, postoperative drains and inpatient admission are part of this treatment.

Background: To evaluate the clinical diagnostic value of third-generation dual-source CT for pulmonary embolism, focusing on the optimization of dual-source CT scanning with dynamic reconstruction in acute pulmonary embolism (PE) and various imaging manifestations.
Methods: Eighty-two patients with pulmonary embolism were enrolled and randomly divided into standard CT angiography (SCTA) and dynamic CT angiography (DCTA). DCTA patients were divided into dynamic CT angiography arterial phase (DCTAa), time phase Angiography reconstruction (TMIP-CTA), and 4D noise reduction TMIP-CTA according to the image reconstruction.

Purpose: To evaluate the effects of four-dimensional noise reduction filtering using a similarity algorithm (4D-SF) on the image quality and tumor visibility of low-dose dynamic computed tomography (CT) in evaluating breast cancer.
Materials And Methods: Thirty-four patients with 38 lesions who underwent low-dose dynamic breast CT and were pathologically diagnosed with breast cancer were enrolled. Dynamic CT images were reconstructed using iterative reconstruction alone or in combination with 4D-SF.
Concentration of Povidone-Iodine Pocket Irrigation in Implant-Based Breast Surgery: A Scoping Review.
Aesthetic Plast Surg
January 2025
Faculty of Medicine, Nursing and Health Sciences, Monash University, Melbourne, Australia.
Background: In implant-based breast surgery, microbial contamination of implant surfaces predisposes complications such as overt periprosthetic infection and has been linked to capsular contracture (CC). Anti-microbial practices, including povidone-iodine (PVP-I) breast pocket irrigation, are routinely employed to minimise these risks. No standardised protocol for using this antiseptic exists, particularly concerning the ideal concentration.
