A rare case of submandibular venous malformation with multiple phleboliths is reported.The clinical pathology,diagnosis ,treat-ment,causes and differential diagnosis of submandibular gland sialolithiasis were discussed based on related literatures.

Objective To investigate the efficacy and safety of 308-nm excimer laser compared to high-intensity ultraviolet radiation for the treatment of active localized vitiligo,and to observe changes in skin lesions before and after the treatment by confocal laser scanning microscopy.Methods Sixty patients with 203 skin lesions of active localized vitiligo and were enrolled into this study,and the vitiligo disease activity (VIDA) score of these patients ranged from 2 to 3.We selected more than 3 skin lesions from a same anatomical site of each patient,one of lesions served as a control and the other skin lesions (≥ 2) were randomly treated with 308-nm excimer laser (laser group) or high-intensity ultraviolet radiation (ultraviolet group).The treatment was conducted twice a week for 25 sessions,and a 3-month follow-up was performed.Results A total of 48 patients with 169 skin lesions completed the trial.The marked response rate was significantly higher in the laser group [66.15％ (43/65)] than in the ultraviolet group [44.64％ (25/56),x2 =8.28,P ＜ 0.01].The patients with a VIDA score of 2 showed a significantly higher marked response rate [67.69％(44/65)] compared with those with a VIDA score of 3 [44.64％(25/56),x2 =6.80,P ＜ 0.01].During the 3-month follow-up,no relapse was observed.Confocal laser scanning microscopy showed that the number of inflammatory cells increased at the dermal-epidermal junction of the intra-and extra-marginal lesional skin.After treatment,the number of inflammatory cells markedly decreased and returned to normal level in lesions.Conclusion Both 308-nm excimer laser and high-intensity ultraviolet radiation are effective in the treatment of active localized vitiligo,but the 308-nm excimer laser shows a more rapid onset of action and a better therapeutic effect.

Objective:To study the orthopedic treatment strategy for hemophilia complicated with musculoskeletal disorders as well as the peri-operative consumption of clotting factor.Methods:Total 338 orthopedic surgeries were performed for 261 patients, average age of 30.6 y (6-65 y) , with hemophilia between January 1996 and December 2019 at our institute. Two hundred and twenty-six patients presented with bleeds within the joints. Sixty-one patients presented with intramuscular bleeds, 45 presented with hemophilic pseudotumors, and six presented with miscellaneous complaints. Strategy of clotting factor replacement therapy was designed as per differences in the level of the operation procedure. Information regarding clinical manifestation, operative strategy, clotting factor consumption, and re-operation for complications was retrospectively recorded. The costs for multiple joint procedure and single joint procedure were studied.Results:We found that 270 of the 338 surgical procedures were major surgical procedures (79.9%) . There were 203 procedures of joint arthroplasty (60%) . Fourteen patients underwent reoperations for local recurrence (4.2%) . The average factor Ⅷ consumption before the surgery was 44.4 ± 8.1 IU/kg. The average FⅧ consumption within postoperative 2 weeks was 40 962 IU (647±177 IU/kg) . Seven type A hemophilic patients developed F Ⅷ inhibitor following the surgical procedure, with an average level of 13.7±11.2 BU/mL. Sixty-eight patients underwent multiple joint procedures under one anesthesia session (26%) . There was no significant difference in the factor consumption between the multiple joint procedure and single joint procedure.Conclusions:Surgical treatment was found to be effective for hemophilic arthropathy and lesion of the musculoskeletal apparatus, with the clotting factor replacement therapy. Multiple joint procedures under one anesthesia were more cost effective for patients with hemophilia, with less factor consumption than staged single joint procedure.
