1. In Vivo Skin 3-D Surface Reconstruction and Wrinkle Depth Estimation Using Handheld High Resolution Tactile Sensing.
The authors developed a handheld tactile imaging probe that reconstructs in vivo 3-D skin topography and estimates wrinkle depth at micron-level precision. Using a custom gel, a learning-based algorithm, and a force-sensing load cell, the system achieved a mean absolute error of 12.55 in wrinkle height estimation across body sites.
Impact: Provides an objective, portable, and high-resolution tool for quantitative assessment of wrinkles and skin texture, addressing a key measurement gap in cosmetic dermatology and clinical trials.
Clinical Implications: Could standardize outcome measurement for anti-aging treatments, enable reproducible pre/post-intervention assessments, and facilitate device/drug development via sensitive, quantitative endpoints.
Key Findings
- Developed a compact GelSight-based tactile probe with custom elastic gel and learning-based reconstruction for 3-D skin mapping.
- Integrated load cell ensures consistent contact force during in vivo acquisition.
- Achieved a mean absolute error of 12.55 for wrinkle height estimation across body locations.
Methodological Strengths
- Hardware-software co-design with force-controlled acquisition
- Quantitative validation with explicit error metric (mean absolute error)
Limitations
- Units and detailed validation cohort characteristics are not reported in the abstract
- Clinical endpoints (e.g., patient-reported outcomes) were not assessed
Future Directions: Multicenter clinical validation against gold-standard imaging, standardization of units and protocols, and integration into longitudinal treatment monitoring.
2. Location-specific outcomes and complications of endoscopic transorbital approaches: A systematic review with novel anatomical grouping.
This PRISMA-guided systematic review introduces a four-group anatomical classification for ETOA and quantifies location-specific outcomes and risks. Visual acuity and proptosis improvements were substantial in orbital, cavernous, and intradural groups, while CSF leak risk varied by location, informing anatomy-based risk assessment and patient selection.
Impact: Provides a practical taxonomy and risk map for ETOA, aligning cosmetic advantages with data-driven safety profiles to guide minimally invasive skull base surgery decisions.
Clinical Implications: Supports individualized approach selection by lesion location, anticipating visual outcomes and CSF leak risk; may reduce complications while maintaining cosmetic benefits.
Key Findings
- Proposed a four-category anatomical grouping for ETOA: orbital (I), cavernous sinus (II), extradural (III), intradural (IV).
- Postoperative visual acuity improved in Groups I (70.6%), II (56.3%), and IV (63.3%).
- Proptosis improved notably in Groups II (95.7%) and IV (87.0%).
- CSF leak rates varied by location: 0% (Groups I and II), 11.8% (Group III), 3.4% (Group IV).
Methodological Strengths
- PRISMA-guided systematic methodology with 28 studies and 382 patients
- Location-specific outcome analysis enabling anatomy-based risk stratification
Limitations
- Heterogeneity of pathologies and outcome measures across included studies
- Predominantly nonrandomized observational evidence limits causal inference
Future Directions: Prospective multicenter registries with standardized endpoints and stratification by pathology subtype to refine the classification and risk estimates.
3. Rib flare distance: a novel and highly reliable radiographic metric of the rib cage deformity in adolescent idiopathic scoliosis.
Rib flare distance (RFD) is introduced as a novel radiographic metric for AIS rib cage deformity, showing excellent inter- and intra-observer reliability and strong discriminatory ability. RFD correlates with established scoliosis measures, suggesting value as an adjunct to improve 3-D characterization relevant to pulmonary function and cosmetic appearance.
Impact: Offers a simple, reproducible radiographic tool to quantify a traditionally hard-to-measure deformity with clinical and cosmetic relevance in AIS.
Clinical Implications: RFD could standardize assessment of rib deformity in AIS, complementing Cobb angle and RVAD, and inform monitoring and surgical planning.
Key Findings
- RFD showed excellent inter- and intra-observer reliability (ICC 0.986 and 0.993).
- Low measurement variability (2.4 mm inter- and 1.8 mm intra-observer) with strong agreement by Bland-Altman.
- Excellent discrimination between AIS and controls (ROC AUC 0.941).
- Moderate correlation with thoracic Cobb angle (r=0.544) and RVAD (r=0.409).
Methodological Strengths
- Independent duplicate measurements with intra- and inter-observer testing
- Comprehensive statistical validation (ICC, Bland-Altman, ROC, correlations)
Limitations
- Retrospective, single-center design with modest sample size
- Lack of external validation and longitudinal responsiveness assessment
Future Directions: External, multicenter validation, determination of clinically meaningful thresholds, and longitudinal studies to link RFD changes to function and cosmetic outcomes.
