ABSTRACT
Objective To observe the effects of platelet-rich plasma (PRP) gel in the treatment of [Ⅳ stage pressure ulcers.Methods A total of 12 patients with stage Ⅳ pressure ulcers were treated with PRP gel from December 2012 to December 2013 in our department.The PRP gel was formed by autologous PRP mixed with thrombin and calcium chloride.The PRP gel was applied to the wound after dressing.Time intervals between dressing were 4 days.Overall pressure ulcer improvement was assessed every week until complete wound healing.Results All stage Ⅳ pressure ulcer wound infection was controlled and fresh granulation tissue was found after 2 times of PRP gel covering.The time of ulcer wound healing were 6-10 weeks (mean 8 weeks).The times of changing the PRP gel were 16.No patients experienced adverse reactions during treatment.Conclusions PRP gel can effectively control the pressure ulcer infection and promote ulcer wound healing.
ABSTRACT
Retrospective analysis was performed for the clinical data of 15 chronic insertion achilles tendinitis patients undergoing platelet-rich plasma (PRP) trigger point injection.The scores of Validated Victorian Institute of Sports Assessment-Achilles (VAS-A) and foot function index (FFI) improved greatly versus pre-treatment (all P ＜ 0.05).Tendon insertion structure inflammation decreased significantly on magnetic resonance imaging.At the last follow-up,all patients recovered normal gait and daily activity.The trigger point injection of PRP is efficacious for chronic insertion achilles tendinopathy.
ABSTRACT
A total of 52 patients with chronic lateral epicondylitis were randomly assigned into platelet-rich plasma (PRP) (n =28) or corticosteroid (n =24) group.The visual analog pain scale (VAS) and Mayo elbow score had no significant difference between two groups within 1 week post-treatment.However,VAS and Mayo elbow score improved more significantly in PRP group versus corticosteroid group at Month 1 and 6 post-treatment (P ＜ 0.05).The PRP trigger point injection treatment of elbow lateral epicondylitis achieved clinical outcomes and it was superior to glucocorticoid treatment.
ABSTRACT
Objective: To investigate the effects of tooth extracti on on dental arch width and alveolar bone width. Methods: D ental arch width and relevant alveolar bone width between canines, second premo lars and first molars were measured on dental casts of 20 cases with Angle II 1 malocclusion before and after tooth extraction treatment. All data were analy sed by SPSS 10.0 statistic software. Results: After treat ment, in maxilla the arch width and alveolar bone width between canines were in creased(P
