1. Surgical and Oncologic Outcomes of Tumescence and Sharp Dissection Versus Electrocautery Dissection in Minimal-Access Nipple-Sparing Mastectomy with Immediate Prosthesis Breast Reconstruction: A Real-World Retrospective Cohort Study.
In a multicenter, propensity-matched cohort of 1252 minimal-access NSM with immediate implant reconstructions, tumescence plus sharp dissection significantly reduced flap necrosis, infection, and implant loss versus electrocautery dissection, and shortened operative time. Five-year overall and disease-free survival did not differ between techniques.
Impact: This large, real-world comparative study identifies an immediately actionable technique to reduce complications in aesthetic-oncologic breast surgery without compromising survival.
Clinical Implications: Adopting tumescence with sharp dissection for minimal-access NSM may lower flap-related complications and implant loss, improve cosmetic outcomes, and shorten operative time without affecting oncologic safety.
Key Findings
- Propensity-matched cohort of 1252 cases across 12 centers compared tumescence+sharp dissection vs electrocautery.
- Lower necrotic complications (5.8% vs 13.0%; p=0.001), infections (2.6% vs 5.6%; p=0.041), and implant loss (0.3% vs 2.2%; p=0.025) with tumescence+sharp dissection.
- Shorter operation time with tumescence+sharp dissection (median 177 vs 201 minutes; p<0.001).
- No significant differences in 5-year overall survival (p=0.938) or disease-free survival (p=0.893).
Methodological Strengths
- Large multicenter real-world dataset with propensity score matching
- Clinically meaningful endpoints including complications and 5-year survival
Limitations
- Retrospective design may be prone to residual confounding despite matching
- Technique selection bias and unmeasured surgeon-level factors cannot be excluded
Future Directions: Prospective, ideally randomized or registry-based comparative studies quantifying patient-reported outcomes and detailed cosmetic assessments would strengthen causal inference and guide guideline updates.
BACKGROUND: Minimal-access nipple-sparing mastectomy (NSM) with immediate prosthesis breast reconstruction results in better cosmetic outcomes than conventional operation. However, the impact of skin flap development techniques on postoperative complications and long-term oncologic safety is largely unknown. This report describes the surgical and oncologic outcomes of tumescence and sharp dissection compared with electrocautery dissection. METHODS: In this real-world retrospective cohort study, 5436 individuals undergoing NSM from 12 centers in China were identified. After exclusions and propensity score-matching, the study included 1252 patients who underwent minimal-access NSM with immediate prosthesis breast reconstruction between January 2016 and December 2022. Perioperative parameters, postsurgical complications, and long-term survival were analyzed. RESULTS: Of the 1252 patients, 313 (25 %) underwent tumescence and sharp dissection, and 939 (75 %) underwent electrocautery dissection. The patients in the tumescence and sharp dissection group had significantly lower rates of necrotic complications (5.8 % vs 13.0 %; p = 0.001), infection (2.6 % vs 5.6 %; p = 0.041), and implant loss (0.3 % vs 2.2 %; p = 0.025) than those receiving electrocautery dissection, with a significantly shorter operation time (median, 177 min; interquartile range [IQR], 132-219 min vs 201 min; IQR, 143-249 min; p < 0.001). The two groups did not differ significantly in 5-year overall survival (p = 0.938) or disease-free survival (p = 0.893). CONCLUSION: Tumescence and sharp dissection was associated with fewer postoperative complications and a shorter operation time than electrocautery dissection for
2. The Risks Associated with Inhalation Exposure to Cosmetics and Potential for Assessment Using Lung Organoids.
This review synthesizes how lung organoids can model human-relevant responses to aerosolized cosmetic exposure, addressing limitations of traditional inhalation toxicology. It outlines organoid construction, comparative advantages, and early applications to assess spray product safety.
Impact: Introduces a mechanistically informed, human-relevant test system to improve safety assessments for aerosolized cosmetics and potentially reduce animal testing.
Clinical Implications: While preclinical, organoid-based inhalation assays can inform formulation changes to mitigate respiratory risks for consumers and workers exposed to cosmetic aerosols.
Key Findings
- Aerosolized cosmetic products present inhalation exposure risks inadequately captured by traditional assessment methods.
- Lung organoids derived from stem cells provide 3D, multicellular structures that better mimic human lung responses.
- Emerging studies demonstrate feasibility of using lung organoids to evaluate cosmetic aerosol effects, supporting regulatory safety assessments.
Methodological Strengths
- Integrative overview of organoid construction and comparative advantages over traditional models
- Translational focus linking preclinical organoid data to regulatory safety assessment needs
Limitations
- Narrative review without formal PRISMA methodology or quantitative synthesis
- Limited number of published cosmetic-specific organoid inhalation studies to date
Future Directions: Develop standardized lung organoid inhalation exposure protocols, inter-lab validation, and benchmarking against human exposure data to support regulatory adoption.
This review addresses the exposure risks associated with the inhalation of aerosolized cosmetic products and explores the utility of lung organoids in assessing these risks. Aerosolized cosmetics such as sprays pose potential health hazards through inhalation, necessitating a thorough evaluation of exposure levels. Traditional methods for assessing inhalation risks have limitations, prompting the exploration of more sophisticated models. Lung organoids, three-dimensional structures derived from stem cells, offer a biologically relevant model for studying lung responses to inhaled substances. This review discusses the construction of lung organoids, their characteristics, and the advantages that they provide over conventional models. Furthermore, it examines existing studies that have employed lung organoids to evaluate the effects of cosmetic inhalation exposure, highlighting the potential of this approach to enhance the safety assessments of cosmetic products. We aim to establish lung organoids as a reliable tool for future research, ensuring the safety and regulatory compliance of cosmetics.
3. Long-term cosmetic and quality of life outcomes after surgery for genital, anogenital, or urogenital injuries resulting from childhood sexual abuse: A scoping review.
Across 12 included studies of reconstructive surgery after childhood sexual assault (before age 10), most patients reported dissatisfaction with external genital cosmetic appearance but satisfactory urinary and fecal continence. Evidence on chronic pain, sexual function, and psychological outcomes is sparse, underscoring the need for standardized long-term follow-up.
Impact: Highlights critical gaps in long-term aesthetic and quality-of-life outcomes after pediatric genital reconstructive surgery, guiding future standards of care and follow-up.
Clinical Implications: Establish standardized, trauma-informed long-term follow-up including validated measures of cosmetic satisfaction, pain, sexual function, and psychological health to tailor care.
Key Findings
- Systematic scoping review following PRISMA-ScR identified 12 studies from 962 records.
- Most patients were dissatisfied with external genital cosmetic outcomes after reconstructive surgery.
- Urinary and fecal continence satisfaction was generally high.
- Little data on chronic pain, sexual function, and psychological outcomes; lack of standardized long-term follow-up protocols.
Methodological Strengths
- PRISMA-ScR–conformant scoping methodology with multi-database search
- Dual independent extraction using Covidence
Limitations
- Only 12 studies with heterogeneous designs limit generalizability
- Lack of standardized outcome measures across studies
Future Directions: Develop consensus core outcome sets (cosmetic satisfaction, continence, sexual and psychological health) and prospective registries to capture long-term trajectories.
BACKGROUND: Although the physical, psychological, physiological, and sexual consequences of childhood sexual abuse have been extensively studied, there remains a gap in understanding with regard to the long-term impacts of restorative surgery following such trauma. OBJECTIVES: To identify and analyze studies that investigate the long-term cosmetic and quality of life outcomes resulting from genital, anogenital, or urogenital injuries following childhood sexual assault and reconstructive surgery. SEARCH STRATEGY: Conforming to PRISMA-ScR guidelines, PubMed, Embase, Scopus, CINAHL, and PsycInfo were searched. SELECTION CRITERIA: Eligible studies included female victims of childhood sexual violence occurring before the age of 10, who also underwent genital, urogenital, or anogenital reconstructive surgery. In addition, studies needed to report at least 6-month postoperative follow-up outcomes for inclusion in this review. DATA COLLECTION AND ANALYSIS: Patient demographics and long-term follow-up outcomes were extracted by two independent authors using Covidence. MAIN RESULTS: The search identified 962 articles, and 12 met the inclusion criteria. Most patients were dissatisfied with the cosmetic appearance of their external genitalia but satisfied with urinary and fecal continence. There was limited information on chronic pain, sexual and psychological impact of it. CONCLUSION: This scoping review underscored the absence of long-term and standardized follow-up protocols for individuals who undergo reconstructive surgery following childhood sexual abuse. Addressing this gap is crucial to effectively incorporate these data so as to improve personalized care and the assessment of long-term quality of life.
