ObjectiveTo explore the value of potaried technique with Trivex system in treatment for venous skin ulcer with deep venous thrombosis sequelae (DVTS) of lower limbs. MethodsTotal 166 patients with venous skin ulcer with DVTS of lower limbs were included in this study. The patients of operation group (94 patients involving 94 legs) were treated by using potaried technique with Trivex system. The patients of nonoperation group (72 patients involving 72 legs) were treated by using nonoperative method. The clinical indexes of skin infection rate, skin necrosis rate, shrinkage rate of wound area, skin depigmentation rate, ulcer healing rate and ulcer recurrence rate were used to assess the clinical curative effect between two groups on 5, 20, 120 and 360 d after operation or treatment, respectively. ResultsThere were no skin infection and skin necrosis in two groups on 5 d after operation or treatment. The rate of shrinkage of wound area and skin depigmentation of patients in operation group were significantly higher than those in nonoperation group on 20 d after operation or treatment 〔(95.8±2.138)% vs. (68.7±3.125)%，P=0.048; (87.6±1.263)% vs. (12.3±1.324)%， P=0.018〕. The rate of the ulcer healing of patients in operation group was significantly higher than that in nonoperation group on 120 d after operation or treatment (97.9%vs. 8.3%， P=0.014). The rate of the ulcer recurrence of patients in operation group was significantly lower than that in nonoperation group on 360 d after operation or treatment (5.3% vs. 97.2%， P=0.015). ConclusionThe potaried technique with Trivex system can be used as one of the surgical treatment methods for venous skin ulcer with DVTS of lower limbs.
To assess the rel iabil ity of diabetic cutaneous ulcer surface area (DCUSA) measurement usingdigital planimetry method (A) and transparency tracing method (B). Methods Images of diabetic cutaneous ulcers from35 inpatients with diabetic skin ulcers from September 2005 to April 2007 were taken by a digital camera once a week or twice a week over a period of 12 weeks, resulting in 305 photographs; the ulcers were traced on a grid with acetate wound tracings, simultaneously. A total of 305 pairs of DCUSA which were calculated respectively throughout digital camera combined with Image J medical imaging software and transparency tracing with grid sheet by two independent observers sequentially were obtained. The intraclass correlation coefficients (ICCs, one-way random effect model) was used as an indicator of chancecorrected agreement to estimate the relative rel iabil ity for the interobserver data. Multiple l inear regression analysis was also used to measure the relationship of these two methods. Results DCUSA obtained from method A and obtained from method B was (4.84 ± 7.73) cm2 and (5.03 ± 7.89) cm2, respectively; no significant difference was found (P gt; 0.05). ICCs was high (ICCs=0.949 for method B and 0.965 for method A), indicating that the relative rel iabil ity for the interobserver was excellent. The method A were highly correlated with measurements obtained from method B (r = 0.957, P lt; 0.05). Conclusion The digital planimetry method described in this study represents a simple, practical, without any wound damage and contamination, and inexpensive technique to accurately evaluate the areas of diabetic cutaneous ulcers. The photographic technique combined with Image J medical imaging software should be considered for wound measurement.
Objective To review and evaluate the clinical application of autologous plateletrich gel (APG) in refractory chronic diabetic cutaneous ulcers. Methods The latest literature was extensively reviewed, and the potential mechanism of APG for healing diabetic cutaneous ulcers was discussed. Results APG accelerated the ulcer healing, especially in healing the refractory diabetic cutaneous ulcers, and the high-level growth factors from the platelet releasate were thought to be the major potential mechanism of the APG action. Conclusion APG can promote the healing of refractory chronic diabetic cutaneous ulcers. Topical haemotherapy withAPG may be considered an adjuvant treatment of a multidisciplinary process and may be useful to the effective therapy of cutaneous ulcers.
Objective To investigate the effect and safety of autologous bone marrow-mononuclear cell (BM-MNC) transplantation on ischemic limb of patients with thromboangiitis obliterans (TAO). Methods Thirteen patients with TAO underwent transplantation of autologous BM-MNC into ischemic muscles of 17 lower limbs. A series of subjective indexes (improvement of pain and cold sensation) and objective indexes including increase of ankle brachial index (ABI), transcutaneous oxygen pressure (TcPO2), and improvement of foot skin ulcer were used to evaluate the effects. Results The outcomes were evaluated after 2 months of transplantation. The pain relief and improvement of cold feeling were in 15 limbs and 16 limbs, respectively. Before transplantation and 2 months after transplantation, ABI was 0.37±0.06 and 0.50±0.17, respectively (Plt;0.05), and TcPO2 of the ischemic legs were (24.59±3.36) mm Hg (1 mm Hg=0.133 kPa) and (35.00±10.44) mm Hg, respectively (Plt;0.05). ABI increased in 9 limbs. TcPO2 elevated in 14 limbs. Skin ulcer improved in 7 limbs. Thirteen patients were followed up from 4 to 18 months (average 8 months), the patients’ symptoms improved in 13 limbs. ABI was 0.45±0.14, which wasn’t different from those before transplantation and 2 months after transplantation (Pgt;0.05). TcPO2 was (33.24±10.43) mm Hg, which was different from those before transplantation and 2 months after transplantation (Plt;0.05) and was elevated in 12 limbs. Skin ulcer healing was in 5 limbs. The ischemic symptoms in 2 patients were not relieved. There was no mortality and high level amputation. The following complications, such as proliferative retinopathy, malignant tumor, myocardial infarction, stroke or hemangioma, were not found in all patients.Conclusion In patients with TAO, intramuscular transplantation of autologous BMMNC is a safe and effective method, and may improve symptoms and accelerate the healing of skin ulcer.
Patients with hypercortisolism may experience cutaneous atrophy, weakened cutaneous barrier function, decreased immunity, opportunistic bacteria or fungal infections, which hinder the healing of cutaneous wounds, and even the ulcers will not heal for a long time, and may progress to chronic ulcers, which are difficult and expensive to treat. It affects the quality of life of patients, and can lead to the spread of infection and life-threatening in severe cases. The pathological mechanism of cutaneous ulcers and delayed healing caused by hypercortisolism is complicated, which is a clinical problem that needs to be solved urgently. This article explains the possible mechanism of hypercortisolism hindering the healing of cutaneous ulcers from the aspects of leading to cutaneous atrophy, pathophysiological abnormalities affecting wound healing, hyperglycemia inhibiting wound healing, and infection and hypercoagulable state, and discusses the possible mechanisms of hypercortisolism hindering the healing of cutaneous ulcers, and its treatment methods, aiming to provide a basis for more in-depth mechanism research and clinical prevention and treatment.
Objective To review the mechanism of cold atmospheric plasma (CAP) in the treatment of chronic skin ulcer, providing a new idea for ulcer therapy. Methods The literature about CAP in the treatment of chronic skin ulcers in recent years was extensively screened and reviewed. The treatment principle, active ingredients, and mechanism were summarized. Results CAP is partial ionized gas discharged by plasma generator in high frequency under high voltage. It contains electrons, positive and negative ions, reactive oxygen species, reactive nitrogen species, and ultraviolet rays. In vitro and animal experiments show that the active ingredients contained in CAP can inactive microorganisms, against biofilm, regulate immune-mediated inflammatory, promoting blood flow, stimulate tissue regeneration and epithelial formation in the course of wounds healing. Conclusion CAP play a role in different stages of chronic skin ulcer healing, with good efficacy and safety, and broad clinical application prospects. But more studies are needed to explore the indications and dosages of CAP therapy.
