Selected Articles
1. Suspension of liposome-based nanocapsules in organic solvents via surface acetylation of chitosan-deposited liposomes.
The authors introduce chitin-deposited liposomes that remain colloidally stable in 100% ethanol and can be transferred to poorly water-soluble solvents (e.g., isododecane), enabling loading of lipophilic actives. Degree of acetylation modulates stability across solvent systems, and membrane rigidity increases, supporting robust capsules for cosmetic and biomedical formulations.
Impact: This first demonstration of liposome-based capsule suspension in neat organic solvents unlocks oil-phase cosmetic vehicles and expands delivery options for lipophilic actives.
Clinical Implications: For dermatology and cosmetic formulation, this platform enables stable oil-based or hydroalcoholic topical products with controlled release and improved loading of lipophilic actives (e.g., antioxidants), potentially enhancing efficacy and skin feel.
Key Findings
- Surface acetylation of chitosan-coated liposomes produced chitin-deposited capsules with increased membrane phase transition temperature, indicating higher rigidity.
- Capsules achieved stable suspension in 100% ethanol and could be transferred to poorly water-soluble solvents (e.g., isododecane) without aggregation or rupture.
- Colloidal stability depended on degree of acetylation and solvent: size increased in water but decreased in water–organic mixtures; stability trends reversed between ethanol/DMSO and acetone.
- Successful loading of a lipophilic cargo (α-tocopherol) into the capsules was demonstrated.
- Comprehensive physicochemical characterization (UV-Vis, TEM, DLS, zeta potential, contact angle) confirmed well-defined core–shell-like assemblies and favorable surface properties.
Methodological Strengths
- Clear control of degree of acetylation enabling systematic assessment of solvent-dependent stability.
- Extensive, multimodal physicochemical characterization and demonstration of payload loading in relevant cosmetic solvents.
Limitations
- No in vivo skin delivery, irritation, or safety data were provided.
- Long-term storage stability and scalability for industrial manufacture were not evaluated.
Future Directions: Evaluate dermal penetration and irritation profiles, long-term stability, and compatibility with diverse actives and oils; benchmark against existing nanoemulsions and liposomes in clinical-grade formulations.
2. Postoperative Differences in Dorsal Aesthetic Lines in Patients Undergoing Dorsal Preservation Rhinoplasty and Conventional Hump Resection.
In a matched retrospective cohort (DPR n=30; CHR n=40), both techniques significantly widened midnose DALs and improved aesthetic (SCHNOS-C) and functional (SCHNOS-O) scores beyond MCID thresholds. No significant intergroup differences in DAL widening were detected, and nasal axis deviation decreased in both groups. AI-based DAL assessment provided objective, quantitative evaluation.
Impact: Provides objective, AI-derived metrics demonstrating comparable aesthetic and functional gains with DPR and CHR, informing surgical planning and patient counseling.
Clinical Implications: Both DPR and CHR are effective options for hump reduction with similar DAL widening and PROM improvements; AI-based DAL analysis can standardize outcome evaluation and guide technique selection.
Key Findings
- Midnose DAL width increased significantly after both DPR (8.835→10.120 mm) and CHR (9.383→10.100 mm); no significant intergroup difference (p=0.089).
- Aesthetic outcomes (SCHNOS-C) improved significantly in all subgroups (p<0.001) with changes exceeding MCID.
- Functional outcomes (SCHNOS-O) significantly improved in the combined cosmetic functional subgroup (p<0.001), exceeding MCID.
- Nasal axis deviation angles decreased significantly postoperatively in both DPR (1.715→1.207, p=0.008) and CHR (1.446→0.751, p=0.004).
- AI-driven analysis provided objective quantification of DALs and axis changes.
Methodological Strengths
- Retrospective matched cohort with both objective (AI DAL metrics) and patient-reported outcomes (SCHNOS).
- Use of MCID thresholds to contextualize clinical relevance.
Limitations
- Retrospective single-center design with potential selection bias.
- Sample size is modest and follow-up duration not specified; no randomized comparison.
Future Directions: Prospective, randomized or multicenter studies with longer follow-up to compare DPR vs CHR stability and patient satisfaction; expand AI tools to 3D morphometrics.
3. Effectiveness and Safety of Non-Surgical Otoplasty Using APTOS Threads: A Retrospective Study.
Among 250 patients (500 ears, age 7–67), EAR-Q domains improved significantly at 1 month and 1 year (p<0.001). GAIS indicated exceptional/very good results in 90% at 1 month and 87% at 1 year. Adverse effects were minimal, with no hematoma, infection, or scarring; pain/numbness resolved by 1 year.
Impact: Demonstrates a minimally invasive, clinic-based alternative to surgical otoplasty with high satisfaction and low complications across a large series and 1-year follow-up.
Clinical Implications: Thread-based otoplasty can be offered to appropriately selected patients seeking reduced downtime and natural contours; standardized protocols and training may optimize outcomes.
Key Findings
- EAR-Q Appearance, Appearance Distress, and Psychological/Social Function scores improved significantly from baseline to 1 month and 1 year (p<0.001).
- GAIS ratings showed exceptional/very good outcomes in 90% at 1 month and 87% at 1 year.
- No hematoma, infection, or scarring was reported; transient pain and numbness resolved by 1 year.
- Procedure was effective under local anesthesia across a wide age range, including 41 patients under 18.
Methodological Strengths
- Large single-center series (n=250) with 1-year follow-up and standardized PROMs (EAR-Q) plus GAIS.
- Clear safety reporting with minimal adverse events.
Limitations
- Retrospective design without a control or surgical comparator; potential selection and reporting bias.
- Single-center experience may limit generalizability and operator-dependent outcomes.
Future Directions: Prospective multicenter comparisons versus surgical otoplasty, durability beyond 1 year, cost-utility analyses, and stratified outcomes by deformity type and age.
