Objective To explore the clinical effect of hair transplantation with autologous follicle on pubic hair reconstruction in women with loss of pubic hair. Methods A total of 38 patients with pubichair loss treated in Hair Transplantation Center of Plastic Surgery Hospital of Chinese Academy of Medical Sciences & Peking Union Medical College were recruited. The scalp strips from the safe donor area were taken and hair transplantation of autologous follicles was conducted for reconstruction. For patients with congenital pubic hair loss, according to the characteristics of female pubic hair distribution and the patient's own requirements, the inverted triangle design was used. For perimenopausal women, the shape of residual pubic hair was considered for design of the region of hair transplantation. For patients with scars, besides scar area implantation was paid attention to, it was also important to design the implantation area above the scar area according to the conditions in order to further cover the scar area with the implanted pubic hair. Results Thirty-eight patients were followed-up for 6 to 24 months. The hairs transplanted grew well. The appearance was close to the normal distribution of pubic hair, resulting in a satisfactory effect. Conclusion It is suggested to reconstruct female pubic hair loss with autologous follicles transplantation. [ABSTRACT FROM AUTHOR]

Objective To compare the efficacy of four methods on removal of calcium hydroxide in root canals. Methods Forty simulated resin root canals with 45° curvature were randomly divided into four groups. After root canal preparation, the apical foramen were sealed with glass-ionomer cement, the root canals were filled with calcium hydroxide, and the root canal orifices were sealed with hard wax. After being placed in a constant temperature water bath at 37 ℃ for 14 days, four methods including needle irrigation, Er: YAG laser irrigation, EDDY working tip irrigation and ultrasonic irrigation were used to remove the calcium hydroxide. The resin root canals before and after calcium hydroxide removal were scanned by cone-beam CT, and the scanning results were imported into Mimics software. Three-dimensional reconstruction of each root canal was performed by Mimics software, and the volume of calcium hydroxide in each root canal was calculated. The volume of calcium hydroxide was V1 before removal and V2 after removal, and the clearance rate was (V1 -V2)/V1 * 100%. Rank sum test was used for statistical analysis. Results There was no significant difference in the initial volume of calcium hydroxide paste among the groups before removal (P > 0.05). After removal, the residual volume of calcium hydroxide paste in Er: YAG laser group was 0.129 6 (0.092 0, 0.174 3) mm³, which was less than the other three groups, and the difference was statistically significant (P < 0.05). The reduction rate of calcium hydroxide paste was 99.63 % (99.53%, 99.70%) in Er: YAG laser group, which was higher than the other three groups, and the difference was statistically significant (P < 0.05). The reduction rates of EDDY group and ultrasonic group were 99.08% (98.85%, 99.19%) and 99.04% (98.51%, 99.15%), respectively. There was no significant difference between the two groups (P > 0.05), but they were higher than needle group 74.99% (64.43%, 88.07%) (P < 0.05), and the difference was statistically significant. Conclusions In this study, Er: YAG laser-activated irrigation, EDDY irrigation and ultrasonic irrigation have better removal effects on calcium hydroxide paste in root canals than traditional needle irrigation. Compared with other four methods, Er: YAG laser-activated irrigation has the highest removal efficiency, EDDY irrigation and ultrasonic irrigation have similar removal efficiency, but none of the four methods could completely remove calcium hydroxide paste from the curved root canals.

Objective To observe the clinical efficacy of hair transplantation in the treatment of frontal fibrosing alopecia. Meth原 ods From October 2016 to now, 6 patients with frontal fibrosing alopecia stable for more than 5 years were recruited. Follicles were obtained by scalp strip cutting from occipital safe area. The density of transplantation was 20~30 units per square centimeter in the fronto- temporal area and 50 units per square centimeter in the eyebrow. Results The incision of donor site in all patients healed well. All patients were followed up for 18 months to 4 years. The growth of transplanted hairs was good. Patients were satisfied with the efficacy. The survival rate of hair was more than 90%. Conclusion Under the premise of ineffective medical treatment and stable condition of patients, hair transplantation is an effective treatment method for frontal fibrosing alopecia in short-term. The long-term results needed further observation. [ABSTRACT FROM AUTHOR]
