Résumé
BACKGROUND:The chitin medical wound dressing can relieve the wound pain, bleeding, and promote wound healing. It has good biocompatibility and antibacterial properties. With the good permeability and natural degradation in the body, it can be used clinicaly as a good biological wound dressing. OBJECTIVE: To evaluate the clinical outcome of the chitin medical wound dressing paste and routine dressings used in changing the dressing and medication. METHODS:We retrospectively studied 60 patients undergoing wound-treatment. They were divided into two groups: chitin medical wound dressing paste group and routine dressing group. Each group had 30 patients. We recorded wound healing rate, detection rate of bacteria, visual analog scale score, healing time and cost of treatment at 3, 7, 14 days after treatment. RESULTS AND CONCLUSION: The wound healing rate, detection rate of bacteria, visual analog scale score, healing time of the chitin medical wound dressing paste group were better than those of the routine dressing change medicine group (P dressing and medication can promote wound healing, reduce the antibacterial infection rate, and obtain better treatment satisfaction.

Objective: Vacuum-assisted closure(VAC) is a new technique for wound treatment,whose clinical application at home is but at the initial stage.The aim of this study was to investigate the procedure,therapeutic course and the effectiveness of the technique in the treatment of chronic wounds.Methods: This study included 12 cases of chronic or infected wound,which were more than 100 cm2 in size,either undermined,or drainage-obstructed,or difficult to heal despite over a month of previous treatment.We used the Freedom Negative Pressure Wounds Therapy Machine and the Ten-Step Management Procedure for a regular course of 30-50 days.We recorded and analyzed the pre-and post-treatment PUSH(pressure ulcer scale for healing) scores,healing modes,healing time and cure rate of all the cases.Results: The 12 cases were treated by VAC for(27.7 ? 22.6) days,of which 9 were cured,1 improved and 2 healed after moisture therapy followed by further treatment in the surgical department.The average healing time was(59.36 ? 22.88) days and the total cure rate was 91.7%.Age is positively correlated with healing time,but other factors showed no significant correlation with healing time and cure rate.Conclusion: The VAC technique is applicable to chronic wounds in patients of all ages,and the best therapeutic course is 30-50 days,which helps to raise the cure rate of intractable wounds.

Objective:Pyoderma gangrenosum(PG) is regarded as a possibly immunity-mediated ulcerative skin disease,which is difficult to be managed and easy to relapse.Few cases of PG have been reported to be treated successfully in the world.This study aimed to investigate the clinical characteristics and difficulties and strategies in the management of mosquito bite-induced ulcer by PG.Methods: We analyzed the clinical characteristics and difficulties in the treatment of a case of mosquito bite-induced leg ulcer complicated by PG.Following the TIME(tissue removal,infection/inflammation control,moisture imbalance correction,and edge of wound revision) principles of wound bed preparation,we treated the ulcer by silver ion dressing + infrared rays,hypertonic saline dressing + infrared rays,hypertonic saline dressing + electrotherapy,and honey dressing + medication at different times.The ulcer size and scores on pain and healing were assessed before each wound care,and the results of each method were analyzed by the SPSS11.0 software.Results: The pain score was continuously reduced with the treatment and the ulcer size and healing score were gradually decreased in the later stage,while in the earlier stage,the ulcer size was even enlarged,with one ulcer becoming two,and the healing score obviously increased.The differences were statistically significant(P
