This article reports a patient with extensive high-pressure injection injury of the hand caused by mistaken injection of polyurethane material into the index finger, who was diagnosed and treated in the Department of Orthopedics of Huzhou Central Hospital in 2019. Both the digital artery and digital nerve were involved, and the polyurethane involved the right palm along the flexor tendon sheath of the index finger and wrist. Due to the lack of X-ray development, the scope of the first debridement was small, and the blood supply to the fingertip was poor. Finally, the patient's right index finger was amputated due to infection and necrosis. MR or B-ultrasound should be perfected before operation to clarify the extent of polyurethane involvement. The initial thorough debridement or multiple debridements are necessary to improve the prognosis. If the blood supply of the fingers is poor, the blood supply can be reconstructed by skin flap transplantation.

This study intended to review the precedents on plastic surgery medical malpractice lawsuits in lower-court trials, classify the reasons of 'limitation of liability' by type, and suggest a standard in the acknowledgement of limitation of liability ratio. The 30 lower-court's rulings on the cases bearing the medical negligence of the defendants acknowledged the liability ratio of the defendants between 30% and 100%. Ten cases ruled that the defendants were wholly responsible for the negligence or malpractice, while 20 cases acknowledged the limitation of liability principle. In the determination of damage compensation amount, the court considered the cause of the victim side, which contributed in the occurrence of the damage. The court also believed that it is against the idea of fairness to have the assailant pay the whole compensation, even there is no victim-side cause such as previous illness or physical constitution of the patient, and applies the legal doctrine on limitation of liability, which is an independent damage compensation adjustment system. Most of the rulings also limited the ratio of responsibility to certain extent. When considering that the legal doctrine on limitation of liability which supports concrete validity for the fair sharing of damage, the tangible classification of causes of limitation of liability suggested in this study would be a useful tool in forecasting the ruling of a plastic surgery medical malpractice lawsuit.

To date, few studies have compared the effectiveness of topical silicone gels versus that of silicone gel sheets in preventing scars. In this prospective study, we compared the efficacy and the convenience of use of the 2 products. We enrolled 30 patients who had undergone a surgical procedure 2 weeks to 3 months before joining the study. These participants were randomly assigned to 2 treatment arms: one for treatment with a silicone gel sheet, and the other for treatment with a topical silicone gel. Vancouver Scar Scale (VSS) scores were obtained for all patients; in addition, participants completed scoring patient questionnaires 1 and 3 months after treatment onset. Our results reveal not only that no significant difference in efficacy exists between the 2 products but also that topical silicone gels are more convenient to use. While previous studies have advocated for silicone gel sheets as first-line therapies in postoperative scar management, we maintain that similar effects can be expected with topical silicone gel. The authors recommend that, when clinicians have a choice of silicone-based products for scar prevention, they should focus on each patient's scar location, lifestyle, and willingness to undergo scar prevention treatment.

The Rejuran(R) is a new filler product made from purified polynucleotides. Here we present data from an animal study and a clinical trial to examine the durability, efficacy and safety of the Rejuran(R) on crow's feet. For the animal study, 25 mice were divided into three groups: Group 1 received phosphate buffered saline (PBS); Group 2 were treated with Yvoire(R); and Group 3 were treated with Rejuran(R). The durability and efficacy of each treatment were assessed by microscopy and staining. In the clinical trial, 72 patients were randomized to receive Rejuran(R) treatment for crow's feet on one side and Yvoire-Hydro(R) on the contralateral side, at a ratio of 1:1. Repeated treatments were performed every two weeks for a total of three times, over a total of 12 weeks' observation. All injections and observations of efficacy and safety were performed by the same two investigators. In the animal study, the Rejuran(R) group showed similar durability and inflammatory response to the Yvoire(R) group. Upon efficacy assessment, the Rejuran(R) group showed the greatest elasticity and collagen composition, and a significant difference in skin surface roughness and wrinkle depth. In the clinical trial, the primary and secondary objective efficacy outcome measure showed no statistical significance between the two groups, and in safety outcomes there were no unexpected adverse effects. Our data suggest that the Rejuran(R), as a new regenerative filler, can be useful to reduce wrinkles, by showing evidence for its efficacy and safety.

Recently, injectable dermal fillers have become important alternatives to surgical procedures for the correction of facial wrinkles. Bovine collagen is the first approved material for filler injection, and several studies have shown its efficacy. However, the risk of developing an allergic reaction and xenogenic transmission of bovine spongiform encephalopathy remain among its disadvantages. In this randomized, double-blinded, split-face study, we compared the efficacy and safety of a porcine collagen filler (TheraFill(R)) with that of a bovine collagen filler (KOKEN(R)) for nasolabial fold correction. A total of sixty one patients with mild to severe nasolabial fold were randomized to receive TheraFill(R) and KOKEN(R) on contralateral sides of the face. During the 12-month follow-up period, improvement in the Wrinkle-Severity Rating Scale score was slightly higher in TheraFill(R) group than KOKEN(R) group, although the difference was not statistically significant. No serious adverse reactions were observed and both materials were tolerable in most cases. In conclusion, the long-term effect of TheraFill(R) on nasolabial fold correction was comparable to that of KOKEN(R), and it may be a good alternative to bovine collagen filler.
