High-energy trauma patients often have multiple injuries and are frequently seen by a physiatrist following their acute care. Acetabular fractures are common in this patient population. Following surgical treatment of acetabular fractures, a very high incidence of heterotopic ossification can occur. We describe 94 patients who underwent posterior surgical fixation of an acetabular fracture. Of these, 87 received heterotopic ossification prophylaxis in the form of irradiation or indomethacin; 5 did not receive prophylaxis. Seven of the 45 patients who were initially started on indomethacin had their medication discontinued for various reasons. Of the 12 patients who did not receive adequate prophylaxis, 5 developed disabling heterotopic ossification. We present our experience with this patient population, and we discuss the importance of adequate prophylaxis for heterotopic ossification.  相似文献

Aims and objectives. To study the material and nursing costs and outcome of wound care at home comparing two dressing groups (occlusive vs. gauze‐based) in surgical patients after hospital dismissal. Background. The large variety in dressing materials and lack of convincing evidence make the choice for optimum local wound care at home cumbersome. Occlusive wound dressings require a lower change frequency than gauze‐based dressings, which appears especially useful for homecare patients and could save costs. Methods. We investigated a consecutive series of 76 patients with wounds, included in a randomized trial comparing occlusive vs. gauze dressings. Daily dressing change frequency, consumption of dressing materials and need for district nursing visits were recorded until wound closure by means of diaries and at outpatient visits. Costs were expressed as means and 95% confidence intervals (CI) after calculation using non‐parametric bootstrapping. Results. Patient groups were similar regarding age, wound size and aetiology. Dressing change frequency in the occlusive group (median: 0·6/day) was significantly (p = 0·008) lower than in the gauze group (1·1/day). Mean daily material costs of modern dressings were €5·31 vs. €0·71 in the gauze group. Mean difference; €4·60 (95% CI, €2·68–€6·83) while daily total (material plus nursing) costs showed no difference between the groups; mean €2·86 (95% CI, €?6·50–€10·25). Wound healing in the gauze‐treated group tended to be quicker than in the occlusive dressing group (medians: 30 vs. 48 days, respectively; log‐rank p = 0·060). Conclusions. The use of occlusive dressings does not lead to a reduction in costs and wound healing time as compared with gauze dressings for surgical patients receiving wound care at home. Relevance to clinical practice. District nurses should reconsider using gauze‐based dressings, particularly in surgical patients with exudating wounds.  相似文献

Heterotopic ossification (HO) is defined as pathological bone formation in soft tissues, for example in muscles, where physiologically there is no osseous tissue present. It is one of the most common complications of total hip joint replacement surgery. A wide variety of risk factors for heterotopic ossification have been identified to date. Almost 90% of total hip arthroplasty patients are at high risk for HO. There are two primary methods of preventing heterotopic ossification: pharmacotherapy with NSAIDs (non steroid anti-inflammatory drugs) and radiotherapy. Symptomatic heterotopic ossifications are treated by extracorporeal shock wave therapy (ESWT) and surgery, followed by NSAID pharmacotherapy or radiotherapy. The arterioles adjacent to areas of heterotopic ossification are usually embolized prior to the operation. This article describes the state of the art in the prevention and treatment of heterotopic ossifications based on the available literature.  相似文献

OBJECTIVE: To assess brain injury severity, autonomic dysregulation and systemic infection as risk factors for the occurrence of heterotopic ossification in patients with severe traumatic brain injury. DESIGN: Historic cohort study. SETTING: Radboud University Medical Centre. SUBJECTS: All consecutively admitted patients with severe traumatic brain injury (admission Glasgow Coma Scale score 8 or less) during the years 2002-2003. MAIN MEASURES: The development of clinically relevant heterotopic ossification, defined as painful swelling of joints with redness and decreased range of motion, confirmed radiographically. RESULTS: Seventy-six (64%) of the 119 patients survived and were eligible for further follow-up. Nine patients (12%) developed 20 symptomatic heterotopic ossifications, in one or more joints. Patients with heterotopic ossification had sustained more severe brain injuries, compared to the group without heterotopic ossification. The mean coma duration in the heterotopic ossification group was 28.11 days (SD 20.20) versus 7.54 days (SD 7.47) in the patients without heterotopic ossification (P < 0.001). The occurrence of autonomic dysregulation (relative risk (RR) 59.55, 95% confidence interval (CI) 8.39-422.36), diffuse axonal injury (RR 20.68, 95% CI 4.92-86.91), spasticity (RR 16.96, 95% CI 3.96-72.57) and systemic infection (RR 13.12, 95% CI 3.01-57.17) were all associated with an increased risk of developing symptomatic heterotopic ossification. However, only autonomic dysregulation had a high positive (88.9%, 95% CI 51.7-99.7) and negative (98.5%, 95% CI 91.9-99.9) predictive value with regard to heterotopic ossification. CONCLUSIONS: The occurrence of autonomic dysregulation may predict the chance of developing heterotopic ossification in patients with severe head injury.  相似文献

Aims: Studies show that VEGF can promote tissue regeneration in diabetic wounds. The aim of this study was to evaluate the effects of a new composite biomaterial, a collagen scaffold with CBD‐VEGF, for wound healing in a diabetic rat model. Materials and methods: We produced a collagen scaffold loaded with CBD‐VEGF, which allowed VEGF to bind to the collagen scaffold. The diabetic rat model was constructed by injecting streptozocin (STZ) peritoneally and removing a 2 x 2.5 cm thick slice of skin from the back of the animal. Animals were randomly divided into 4 groups: blank control (BC Group, n = 24), collagen scaffold loaded with PBS (PBS Group, n = 24), collagen scaffold loaded with NAT‐VEGF (NAT‐VEGF Group, n = 24), and collagen scaffold loaded with CBD‐VEGF (CBD‐VEGF Group, n = 24). Wounds of the BC Group were covered with gauze and those of the PBS, NAT‐VEGF and CBD‐VEGF Groups were grafted by corresponding collagen scaffolds, respectively. Healing rates were calculated and compared among groups. Wound tissue was evaluated by histologic analysis. Results: The CBD‐VEGF group showed a higher wound healing rate, better vascularization and higher level of VEGF in the granulation tissue wound compared with NAT‐VEGF and PBS groups. Conclusions: The collagen scaffold with CBD‐VEGF promoted wound healing in a diabetic rat model, which could potentially provide better therapeutic options for the treatment of diabetic wounds.

At sites of injury, macrophages secrete growth factors and proteins that promote tissue repair. While this central role of the macrophage has been well studied, the specific stimuli that recruit macrophages into sites of injury are not well understood. This study examines the role of macrophage inflammatory protein 1alpha (MIP-1alpha), a C-C chemokine with monocyte chemoattractant capability, in excisional wound repair. Both MIP-1alpha mRNA and protein were detectable in murine wounds from 12 h through 5 d after injury. MIP-1alpha protein levels peaked 3 d after injury, coinciding with maximum macrophage infiltration. The contribution of MIP-1alpha to monocyte recruitment into wounds was assessed by treating mice with neutralizing anti-MIP-1alpha antiserum before injury. Wounds of mice treated with anti-MIP-1alpha antiserum had significantly fewer macrophages than control (41% decrease, P < 0. 01). This decrease in wound macrophages was paralleled by decreased angiogenic activity and collagen synthesis. When tested in the corneal micropocket assay, wound homogenates from mice treated with anti-MIP-1alpha contained significantly less angiogenic activity than control wound homogenates (27% positive for angiogenic activity versus 91% positive in the control group, P < 0.01). Collagen production was also significantly reduced in the wounds from anti-MIP-1alpha treated animals (29% decrease, P < 0.05). The results demonstrate that MIP-1alpha plays a critical role in macrophage recruitment into wounds, and suggest that appropriate tissue repair is dependent upon this recruitment.  相似文献

Human periodontal ligament stem cells (hPDLSCs) are promising for tissue engineering applications but have received relatively little attention. Human platelet lysate (HPL) contains a cocktail of growth factors. To date, there has been no report on hPDLSC seeding on scaffolds loaded with HPL. The objectives of this study were to develop a calcium phosphate cement (CPC)–chitosan scaffold loaded with HPL and investigate their effects on hPDLSC viability, osteogenic differentiation and bone mineral synthesis for the first time. hPDLSCs were harvested from extracted human teeth. Scaffolds were formed by mixing CPC powder with a chitosan solution containing HPL. Four groups were tested: CPC–chitosan + 0% HPL (control); CPC–chitosan + 2.66% HPL; CPC–chitosan + 5.31% HPL; CPC–chitosan + 10.63% HPL. Scanning electron microscopy, live/dead staining, CCK-8, qRT-PCR, alkaline phosphatase and bone minerals assay were applied for hPDLSCs on scaffolds. hPDLSCs attached well on CPC–chitosan scaffold. Adding 10.63% HPL into CPC increased cell proliferation and viability (p < 0.05). ALP gene expression of CPC–chitosan + 10.63% HPL was 7-fold that of 0% HPL at 14 days. Runx2, OSX and Coll1 of CPC–chitosan + 10.63% HPL was 2–3 folds those at 0% HPL (p < 0.05). ALP activity of CPC–chitosan + 10.63% HPL was 2-fold that at 0% HPL (p < 0.05). Bone minerals synthesized by hPDLSCs for CPC–chitosan + 10.63% HPL was 3-fold that at 0% HPL (p < 0.05). This study showed that CPC–chitosan scaffold was a promising carrier for HPL delivery, and HPL in CPC exerted excellent promoting effects on hPDLSCs for bone tissue engineering for the first time. The novel hPDLSC–CPC–chitosan–HPL construct has great potential for orthopedic, dental and maxillofacial regenerative applications.

This study compares the effect of a daily gauze dressing with that of a lipido-colloid dressing on the time taken to make up the dressing and efficacy of the management of traumatic digital wounds. This is a randomized controlled trial of 28 patients (16 experimental and 12 control) with injuries to their fingers and loss of tissue. The patients in the experimental and control groups were given a lipido-colloid dressing and a daily gauze dressing, respectively. The patients'wounds were assessed in terms of the size of the wound and the time it took for the wound to heal. The findings showed that patients in the experimental group had a faster recovery time from the healing of their wound than the control group (p= .024). The findings can help to establish an evidence-based practice in the management of traumatic digital wounds in clinical settings.  相似文献

BackgroundTopical application of lidocaine in wounds has been studied in combination with vasoconstrictive additives, but the effect without these additives is unknown. The objective was to examine use of lidocaine-soaked gauzes without vasoconstrictive agents, in traumatic wounds in adult patients, applied in triage.MethodsA prospective pilot study was performed during 6 weeks in the Emergency Department of a level 1 trauma center. Wounds of consecutive adult patients were treated with a nursing protocol, consisting of lidocaine hydrochloride administration directly into the wound and leaving a lidocaine-soaked gauze, until wound treatment. Primary outcome was need for infiltration anesthesia. Secondary outcomes were Numerical Rating Scale (NRS) pain scores, adverse events and patient and physician satisfaction.ResultsForty patients with a traumatic wound were included, 85% male with a wound on the arm. Thirty-seven patients needed a painful procedure as wound treatment. When suturing was necessary, 77% required additional infiltration anesthesia. Mean NRS pain scores decreased from 3.3 to 2.2 after application of the lidocaine gauze. No adverse events were recorded. Of the patients, 60% were satisfied with use of the lidocaine gauzes, compared to 40% of physicians.ConclusionLidocaine hydrochloride (2%) gauzes without vasoconstrictive additives cannot replace infiltration anesthesia in traumatic wounds.  相似文献

Chronic wounds cost several billion dollars of public healthcare spending annually and continue to be a persistent threat globally. Several treatment methods have been explored, and all of them involve covering up the wound with therapeutic dressings that reduce inflammation and accelerate the healing process. In this present study, morin (MOR) was loaded onto hydrogel scaffolds prepared from psyllium seed husk polysaccharide (PSH), and human hair keratins (KER) crosslinked with sodium trimetaphosphate. ATR-FTIR confirmed the presence of the constituent chemical ingredients. SEM images of the scaffold surface reveal a highly porous architecture, with about 80% porosity measured by liquid displacement measurement, irrespective of the morin concentration. Swelling assays carried out on the scaffolds portray an ability to absorb up to seven times their dry weight of fluids. This makes them attractive for guiding moist wound healing on medium exuding wounds. An Alamar blue assay of NIH/3T3 fibroblast cells shows that cell viability decreases in the first 24 h but recovers to 85% in comparison to a control after 48 h. SEM images of fibroblast cells grown on the scaffolds confirm cellular attachment. An in vivo diabetic wound healing study showed that PSH + KER + MOR scaffold treatment significantly reduced the re-epithelialization time (p < 0.01) and enhanced the rate of wound contraction (p < 0.001), by accelerating collagen synthesis in diabetic rats compared to controls.

Morin loaded polysaccharide–protein composite scaffolds enhance diabetic wound healing.  相似文献
