1. Biomimetic hyaluronic acid-stabilized zinc oxide nanoparticles in acne treatment: A preclinical and clinical approach.
The study introduces HA-stabilized ZnO nanoparticles that preferentially localize to sebaceous-rich acne-prone areas without penetrating the skin. They exhibit >16-fold selective antibacterial activity against C. acnes over S. epidermidis, improved acidic stability, and sustained Zn release, addressing safety and selectivity concerns of conventional ZnO.
Impact: By combining biomimetic synthesis with targeted delivery and selective antimicrobial action, this work offers a potentially safer, microbiome-sparing acne therapy with translational potential.
Clinical Implications: If validated in controlled trials, HA‑ZnO could enable topical treatments that selectively suppress C. acnes while sparing commensals, potentially reducing irritation, dysbiosis, and resistance risks compared with broad-spectrum agents.
Key Findings
- HA-ZnO targeted acne-prone, sebaceous-rich areas without penetrating the skin.
- Selective antibacterial activity: >16-fold higher killing of C. acnes than S. epidermidis.
- HA coating enhanced ZnO stability in acidic conditions, mitigating potential toxicity and side effects.
- Sustained release behavior of Zn supported prolonged antimicrobial activity.
Methodological Strengths
- Biomimetic mineralization strategy enabling stable HA-ZnO formulation.
- Combined preclinical characterization with initial clinical application context and quantitative selectivity assessment.
Limitations
- Clinical study design details (sample size, controls, endpoints) are not reported in the abstract.
- Long-term safety, microbiome impact, and comparative effectiveness versus standard therapies remain untested.
Future Directions: Conduct randomized controlled clinical trials to quantify efficacy, durability, microbiome effects, and safety; optimize dosing and formulation; evaluate resistance development risk.
2. Low Energy Ultrapulse CO
In an 80-patient randomized study of periorbital rejuvenation, combination therapy outperformed low-energy ultrapulse CO2 laser alone across GAIS, wrinkle reduction, texture, elasticity, and hydration, with fewer contour depressions. Both regimens were well tolerated, and satisfaction favored the combination.
Impact: Provides randomized comparative evidence supporting combination therapy over laser monotherapy for periorbital aging, with multidimensional improvements and patient satisfaction.
Clinical Implications: Clinicians may consider combination regimens to enhance periorbital wrinkle and laxity outcomes beyond LEUCO alone, while monitoring for long-term durability and standardized protocols.
Key Findings
- Randomized allocation of 80 patients to laser monotherapy versus combination therapy.
- Combination therapy achieved higher GAIS effectiveness and greater improvements in wrinkles, texture, elasticity, and moisture at all time points.
- Upper eyelid depression and infraorbital hollowing scores were lower with combination therapy; both regimens were well tolerated, with higher satisfaction in the combination group.
Methodological Strengths
- Randomized comparative design.
- Multiple objective and patient-reported outcomes assessed across time points.
Limitations
- Abstract does not detail the specific adjunct in the combination regimen, treatment parameters, or follow-up duration.
- Blinding and multicenter enrollment are not reported, potentially limiting generalizability.
Future Directions: Blinded multicenter RCTs with standardized protocols and longer follow-up to assess durability, safety, and cost-effectiveness; mechanistic studies on synergy.
3. Feasibility and outcomes of remote-access endoscopic and robotic lateral neck dissection for thyroid cancer: a scoping review.
This scoping review finds that multiple remote-access endoscopic/robotic approaches to lateral neck dissection can match conventional oncologic clearance for levels IIa, III, IV, and V (transoral generally limited to III–IV) while delivering superior cosmetic results. Technique-specific pros/cons highlight the need for careful patient selection.
Impact: By synthesizing outcomes across approaches, the review supports offering hidden-scar options without compromising oncologic adequacy, informing shared decision-making and technique selection.
Clinical Implications: Remote-access LND can be offered to selected thyroid cancer patients prioritizing cosmetic outcomes, recognizing transoral limitations in level coverage and the importance of surgeon experience.
Key Findings
- Identified gasless infraclavicular, breast-chest, gasless transaxillary, bilateral axillo-breast, gasless retroauricular, transoral, and combined remote-access approaches for LND.
- Lateral lymph node yield, complication rates, and recurrence rates were comparable across remote-access approaches.
- Extent of dissection matched conventional surgery for levels IIa, III, IV, and V, with transoral approaches generally limited to levels III and IV; cosmetic outcomes were significantly superior with remote-access techniques.
Methodological Strengths
- Systematic literature search across major databases with structured synthesis of techniques and outcomes.
- Comparative assessment of anatomic level coverage, complications, and cosmetic outcomes.
Limitations
- Heterogeneity of included studies, predominance of nonrandomized designs, and potential selection bias.
- Learning curve effects and center expertise may influence outcomes; scoping review without meta-analysis.
Future Directions: Prospective comparative studies and registries evaluating long-term oncologic outcomes, patient-reported satisfaction, cost-effectiveness, and learning curves across approaches.
