Study design: This was a Phase 3, prospective, open-label, evaluator-blinded, single-center pilot study of SGP-HA use in lip augmentation. The primary efficacy objectives were to investigate the efficacy of SGP-HA in lip augmentation and to assess subject satisfaction with the procedure 12 weeks after treatment. Secondary efficacy objectives were to validate 3D imaging to measure lip augmentation, identify subject satisfaction at all points in time, and identify the duration of lip augmentation and palpability of SGP-HA in the lips. The primary safety objective was to assess the incidence, duration, and severity of all adverse experiences. Results: All 20 subjects and the treating investigator indicated improvement in the appearance of subjects’ lips at weeks 2, 6, and 12. SGP-HA administered for augmentation was well tolerated. Four (20%) subjects treated with SGP-HA experienced 7 treatment-emergent adverse events (TEAEs). Conclusions: Results of this study show promising efficacy and an absence of safety issues with the use of SGP-HA in lip augmentation.展开更多

Members of these communities often use account names instead of real names. When they meet in the real world, they will find it useful to have a tool that enables them to associate the faces in fiont of them with the account names they know. This paper proposes a method that enables a person to identify the account name of the person （＂target＂） in front of him/her using a smartphone. The attendees to a meeting exchange their identifiers （i.e., the account name） and GPS information using smartphones. When the user points his/her smartphone towards a target, the target＇s identifier is displayed near the target＇s head on the camera screen using AR （augmented reality）. The position where the identifier is displayed is calculated from the differences in longitude and latitude between the user and the target and the azimuth direction of the target from the user. The target is identified based on this information, the face detection coordinates, and the distance between the two. The proposed method has been implemented using Android terminals, and identification accuracy has been examined through experiments.展开更多

However, treatment of the glabella is associated with injection-related complications. The safety of injections can be increased through a thorough understanding of the anatomy and precise injection planes. The authors propose a 3-point injection technique for forehead augmentation in Asian patients that uses CHAP-hyaluronic acid (CHAP-HA) filler. The longevity of the filler was assessed using high-resolution ultrasound (HRU) imaging. Fifteen patients were examined using HRU before and immediately after treatment and at 1 month, 3 months, 6 months, and 12 months. As evident in HRU imaging, CHAP-HA remained visible within surrounding tissue for 6.4 ± 3.7 months. The mean Global Aesthetic Improvement Scale rating was 2.4 ± 0.5 immediately after treatment, 2.8 ± 0.3 at 1 month, 2.7 ± 0.5 at 3 months, 2.1 ± 0.6 at 6 months, and 1.5 ± 0.6 at 12 months. Minimal side effects were reported. The authors demonstrated that CHAP-HA filler may be an optimal candidate for forehead filler augmentation using a 3-point injection technique.展开更多

The proposed human friendly interface is implemented by a three-stage algorithm: Detection and sizing of the user's body, detection of reference points based on face detection and augmented reality markers, and superimposition of the clothing over the user's image. Compared to other existing VFR systems, key difference is the lack of any proprietary hardware components or peripherals. Proposed VFR is software based and designed to be universally compatible as long as the device has a camera. Furthermore, JAVA implementation on Android based mobile systems is computationally efficient and it can run in real-time on existing mobile devices.展开更多

The relative polymerization and chain length of the compound determines its viscosity, as measured by centistokes (cp). It is available in 350, 1000 and 5000 cp - the higher the number, the more viscous the oil. Most of the reports used 1000-cp silicone oil for filling purposes and due to high viscosity, only microdroplet injection technique is recommended to avoid complications. This is the first report of patient series using liquid silicone with a 350-cp viscosity The objective of this study was to explore the reliability and efficacy of low viscosity liquid silicone for lower face contour correction. Methods: Lower facial region of 43 patients including chin, nasolabial and melolabial regions were treated by low viscosity (350 cp) liquid silicone. Instead of microdroplet tehniqe, retrograde linear threading technique was used. Total injection volume was 6.0 ± 3.9 mL. At least two sessions were required for complete correction which are spaced one month apart. Overcorrection was avoided. The treated areas had a soft and natural feeling with no lumpiness and stiffness. Results: Mean follow-up period was 16.8 ± 14.3 months. The mean aesthetic satisfaction score was 4.51. No migration of the material was seen which is revealed by palpation and no major complication was encountered. None of the patients had any complaints regarding late facial deformity due to silicone migration. Conclusion: Low viscosity liquid silicone is effective, well-tolerated and easy to use. It can be used as an alternative to higher viscosity silicones to avoid technical errors and complications.展开更多
