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.
Liposomes are valuable drug and cosmetic carriers but face limitations in stability and active loading from external phases. Polymer-coated liposomes (liponanocapsules) have improved robustness, and this study advances the approach by acetylating chitosan-coated liposomes to form chitin-deposited capsules, leveraging chitin's biocompatibility and insolubility to enhance the structural and colloidal stability in organic solvents and oils. This represents the first report of suspensions of liposome-based capsu
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.
BACKGROUND: Dorsal preservation rhinoplasty (DPR) and conventional hump resection techniques (CHR) are two distinct methods for nasal hump reduction, affecting dorsal aesthetic lines (DALs) and midvault stability differently. There is limited existing evidence regarding variations in DALs width, between these techniques. OBJECTIVES: To quantify DALs width variations and compare functional and aesthetic outcomes between DPR and CHR techniques in primary rhinoplasty patients. METHODS: A retrospective matche
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.
IMPORTANCE: Prominent ear deformities can negatively impact self-esteem and social well-being. Surgical otoplasty is effective but is associated with complications, longer recovery, and altered ear contours. OBJECTIVE: To evaluate the effectiveness and safety of non-surgical otoplasty using Aptos threads for the correction of prominent ear deformities and other auricular deformities. DESIGN: Retrospective observational study. SETTING: Single-center study conducted at AL-GOUSOUS Medical Center, Amman, Jo
