Introduction
Chronic, non-healing wounds are often characterised by an excessive, and detrimental, inflammatory response. We review our experience of using a combined topical steroid, antibiotic and antifungal preparation in the treatment of chronic wounds displaying abnormal and excessive inflammation.Methods
A retrospective review was undertaken of all patients being treated with a topical preparation containing a steroid (clobetasone butyrate 0.05%), antibiotic and antifungal at a tertiary wound healing centre over a ten-year period. Patients were selected as the primary treating physician felt the wounds were displaying excessive inflammation. Healing rates were calculated for before and during this treatment period for each patient. Changes in symptom burden (pain, odour and exudate levels) following topical application were also calculated.Results
Overall, 34 ulcers were identified from 25 individual patients (mean age: 65 years, range: 37–97 years) and 331 clinic visits were analysed, spanning a total time of 14,670 days (7,721 days ‘before treatment’ time, 6,949 days ‘during treatment’ time). Following treatment, 24 ulcers demonstrated faster rates of healing, 3 ulcers showed no significant change in healing rates and 7 were healing more slowly (p=0.0006). Treatment generally reduced the burden of pain and exudate, without affecting odour.Conclusions
In normal wound healing, inflammation represents a transient but essential phase of tissue repair. In selected cases, direct application of a steroid containing agent has been shown to improve healing rates, presumably by curtailing this phase. Further evaluation is required to establish the role of preparations containing topical steroids without antimicrobials in the management of chronic wounds. 相似文献92.

Through correlation with cryomicrotic sections, the appearance of the trigeminal nerve and its branches on magnetic resonance images is described in healthy individuals and in patients with tumors involving this nerve. Coronal images are best for defining the different parts of the nerve and for making a side-to-side comparison. Sagittal images are useful to demonstrate tumors involving the gasserian ganglion. 相似文献

Expression of hematoregulatory cytokines such as interleukin-1 (IL-1) in response to cytotoxic chemotherapy hastens hematopoietic recovery, but may also potentiate myelotoxicity if myeloid progenitors enter cell cycle before drug clearance. In the present study, the ability of recombinant human IL-1 receptor antagonist (IL-1ra) to protect hematopoietic progenitors was studied in a murine model of cyclophosphamide (CPA)-induced myelotoxicity. CF-1 female mice received 200 mg/kg CPA and either 10 mg/kg IL-1ra or an equal volume of 0.05% human serum albumin (HSA) intraperitoneally (i.p.), followed 12 hours later by IL-1ra or HSA. CPA and IL-1ra increased absolute neutrophil counts (ANCs) at days 2 (P = .001) and 14 (P = .0025) after CPA. In IL- 1ra-treated mice, colony-forming units granulocyte-macrophage (CFU- GM)/tibia were increased twofold and threefold at days 2 (P = .0047) and 7 (P = .023), respectively, whereas high proliferative potential colony-forming cells (HPP-CFC)/tibia were decreased twofold to threefold at 8 hours (P = .039) and 24 hours (P = .0033), but were approximately threefold higher than HSA-treated mice at day 7 after CPA. Coadministration of CPA and IL-1 enhanced myelotoxicity compared with mice injected with CPA and IL-1ra or HSA. In vivo, IL-1ra protected HPP-CFC, but not CFU-GM, from hydroxyurea suicide after a single dose of CPA, suggesting that IL-1ra inhibited cycling of HPP- CFC. In vitro, IL-1ra did not alter proliferation of CFU-GM, but inhibited IL-1-enhanced proliferation of HPP-CFC. These data suggest that IL-1ra acts as an indirect negative regulator of hematopoiesis and protects HPP-CFC from CPA, possibly by inhibiting IL-1-enhanced proliferation of early myeloid progenitors. 相似文献
