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.
Acne vulgaris is a common chronic inflammatory skin condition, often caused by C. acnes infection. While ZnO has shown promise as an antibacterial agent in acne treatment, concerns over toxicity and non-selective bacterial killing remain. In this study we developed a hyaluronic acid-stabilized nano‑zinc oxide (HA-ZnO) formulation aimed at enhancing the therapeutic efficacy and safety of ZnO for acne treatment. HA-ZnO was synthesized through biomimetic mineralization. HA-ZnO targeted acne-prone areas, especially sebaceous glands, without skin penetration. HA-ZnO demonstrated selective antibacterial activity against C. acnes, exhibiting a killing efficacy more than 16 times greater than that against S. epidermidis. The HA coating also improved ZnO's stability in acidic conditions, mitigating potential toxicity and side effects. Additionally, the sustained release of Zn
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.
OBJECTIVE: This paper focuses on the efficacy of low energy ultrapulsed CO METHODS: Eighty patients with periorbital wrinkles and eyelid laxity were randomly assigned to a laser group ( RESULTS: The combination group exhibited higher overall effective rate of GAIS, greater improvements in wrinkles, texture, skin elasticity, and moisture at all time points, and lower upper eyelid depression and infraorbital hollowing scores than the laser group. While both treatments were well tolerated, patient satisfaction was higher in the combined group than the laser group. CONCLUSION: LEUCO
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.
BACKGROUND: Remote-access endoscopic and robotic thyroid surgery has progressively evolved over the decades to minimize visible neck scarring. Various approaches, including axillary, anterior chest, breast, postauricular, and transoral routes, have been developed, extending their application to lateral neck dissection (LND) in thyroid cancer. This study aims to comprehensively review and synthesize recent literature on remote-access endoscopic and robotic techniques for LND, with a focus on outcomes, advantages, and limitations. METHODS: A systematic literature review was conducted using PubMed and Cochrane Library databases. Search terms included "lateral neck dissection", "thyroid cancer", "remote-access", "robotic", "endoscopic", and "video-assisted". Eligible studies were analyzed to provide an in-depth overview of current techniques, addressing the following aspects: (I) incision location; (II) surgical procedures; (III) complications and surgical outcomes; and (IV) advantages and limitations of each approach. RESULTS: Various remote-access techniques for LND were identified, including gasless infraclavicular, breast-chest, gasless transaxillary, bilateral axillo-breast, gasless retroauricular, transoral, and combined approaches. Outcomes, including the number of removed lateral lymph nodes, complication rates, and recurrence rates, were comparable across remote-access approaches. The extent of dissection achieved with these techniques was equivalent to conventional approaches for levels IIa, III, IV, and V, except for the transoral approach, which was generally limited to levels III and IV. Postoperative cosmetic outcomes were significantly superior with remote-access techniques. CONCLUSIONS: Remote-access approaches for thyroidectomy combined with LND are both feasible and safe, achieving complete resection of targeted neck levels with excellent surgical and cosmetic outcomes. The unique advantages and limitations of each method underscore the importance of careful patient selection to optimize clinical benefits.
