Summary
Three impactful studies span dermatologic oncology, ophthalmic surgery, and environmental safety of cosmetic ingredients. Multicenter data support electronic brachytherapy as a well-tolerated, cosmetically favorable option for low-risk non-melanoma skin cancer, while a large office-based series demonstrates safe, cost-effective pterygium surgery with high patient satisfaction. A critical review synthesizes ecotoxicological risks of sunscreen UV filters, highlighting research gaps critical to safer formulation and regulation.
Research Themes
- Non-surgical dermatologic oncology and cosmetic outcomes
- Office-based ophthalmic surgery safety and cost-effectiveness
- Environmental safety of cosmetic sunscreen UV filters
Selected Articles
1. Ecotoxicological effects of sunscreen derived organic and inorganic UV filters on marine organisms: A critical review.
This critical review synthesizes evidence from 111 studies on the ecotoxicology of sunscreen UV filters, showing a predominant focus on organic filters (notably oxybenzone) and frequent use of oxidative-stress endpoints in bivalves. It highlights methodological gaps—limited taxa, life stages, and environmental realism—and recommends incorporating dietary exposure and UV lighting in future experiments to better inform safer formulation and policy.
Impact: Given global sunscreen use and regulatory scrutiny, this synthesis will likely shape toxicological testing standards and ingredient reformulation toward lower environmental impact.
Clinical Implications: Dermatology and public health stakeholders should consider the environmental profiles of UV filters when advising on sunscreen use and when selecting ingredients, balancing skin cancer prevention with ecosystem health.
Key Findings
- Screened 111 peer-reviewed studies (Jan–Oct 2024); 60% assessed organic UV filters, with oxybenzone the most studied (57%).
- Inorganic filters comprised 40% of studies; bivalves were the most commonly tested taxa (24%).
- Oxidative stress assays dominated (≈40%) across both organic and inorganic studies.
- Key gaps include limited taxa/life-stage coverage and lack of realistic exposure conditions; future work should include dietary uptake and UV lighting.
Methodological Strengths
- Comprehensive multi-database retrieval and quantitative description of topic distribution.
- Clear articulation of methodological gaps and actionable recommendations for experimental realism.
Limitations
- Not presented as a PRISMA-compliant systematic review; no formal meta-analysis.
- Temporal scope limited to 2024 publications may omit earlier foundational studies.
Future Directions: Adopt standardized, environmentally realistic test systems incorporating UV light, dietary uptake, and multiple life stages across diverse taxa to refine risk assessment and guide ingredient reformulation.
2. The Elekta Esteya
In a six-center phase IV cohort (205 patients/236 lesions), high-dose-rate electronic brachytherapy for low-risk NMSC achieved excellent/good cosmesis in 90–100% of assessments (slightly lower early post-therapy) with only one recurrence over a median 24.2 months. Acute erythema peaked at 1 month and resolved by 6 months; chronic toxicities were limited to low rates of hypopigmentation and telangiectasia.
Impact: Provides multi-center, longitudinal evidence supporting EBx as a non-surgical alternative with high cosmetic satisfaction and very low recurrence for low-risk NMSC.
Clinical Implications: EBx can be offered as a first-line non-surgical option for appropriately selected low-risk NMSC patients, especially those with surgical risk, cosmesis concerns, keloid tendency, wound-care limitations, or on anticoagulation.
Key Findings
- Excellent/good cosmesis in 90–100% of both HCP and patient ratings; HCP early (1–3 months) rating 83–87%.
- Only one recurrence among 236 lesions (0.42%) with median follow-up 24.2 months (max 73.5 months).
- Most common acute AE was erythema (34.1% at 1 month), resolving to 0% by 6 months; chronic hypopigmentation and telangiectasia occurred at low rates.
- Treatment schemes delivered 69–72 Gy (BED) across six centers, indicating feasibility and generalizability.
Methodological Strengths
- Multicenter cohort with standardized high-dose-rate EBx protocols and dual (HCP and patient) cosmetic assessments.
- Longitudinal follow-up up to 73.5 months capturing both acute and chronic toxicities.
Limitations
- Non-randomized cohort without a surgical comparator; potential selection bias.
- Heterogeneity in fractionation schemes and a median follow-up of ~2 years may limit long-term recurrence assessment.
Future Directions: Prospective randomized comparisons versus Mohs surgery or standard excision focusing on long-term control, cosmesis, and cost-effectiveness; optimization of fractionation for specific lesion locations.
3. The Safety of Office-Based Pterygium Surgery.
In 1071 office-based pterygium surgeries, 1-year recurrence was 2.04% with no infections, pain scores under 1, and cosmetic satisfaction over 88%. Average cost was $1,795, substantially lower than surgical centers and hospitals, supporting office-based surgery as a safe, cost-effective model.
Impact: Large-scale real-world evidence supports shifting a common ocular surface procedure to office settings without compromising safety or cosmetic outcomes while reducing costs.
Clinical Implications: Office-based pterygiectomy can be adopted with topical anesthesia and oral sedation, maintaining low recurrence and high satisfaction while reducing facility costs; avoid epinephrine in peribulbar anesthesia to mitigate CRAO risk.
Key Findings
- Among 393 cases with 1-year data, recurrence was 2.04%, dellen 3.05%, granuloma 3.82%, and ptosis 2.6%; no infections.
- Patient-reported pain remained <1 peri- and postoperatively; cosmetic satisfaction exceeded 88% at 1 year.
- Average office-based cost was $1,795 versus $3,812.50 at surgical centers and $5,562 at hospitals.
- One CRAO linked to epinephrine-containing peribulbar anesthesia prompted removal of epinephrine from the regimen.
Methodological Strengths
- Very large case series with standardized workflow and multiple scheduled follow-ups up to 1 year.
- Comprehensive outcomes including complications, pain, cosmetic satisfaction, and detailed cost comparison.
Limitations
- Retrospective design without randomized or concurrent OR-based control; potential selection and reporting bias.
- Only 393/1015 cases had 1-year follow-up data; two-surgeon experience may limit generalizability.
Future Directions: Prospective comparative trials versus ambulatory center/hospital settings; standardized protocols to minimize recurrence and optimize cosmesis; broader multi-operator validation.
