Chronic and non healing wounds, necrotic wounds and contused and devitalized wounds require debridement to rid the wounds of all these impediments that encourage bacterial growth and multiplications with consequent impairment of wound healing. Whereas there are several methods of wound debridement with their peculiar indications, merits and demerits, the ideal method of debridement is yet to be discovered. The aim of this study is to investigate clinically the ability of honcrivine (honey plus acriflavine 0.1%) to chemically debride various wounds in routine clinical practice. One hundred and eighty nine consecutive patients managed by the author between June 1995 and June 2005 were included in this study. They were 125 males and 64 females and their ages ranged between 6 and 78 years. Initially swab was taken for bacterial culture from each wound before being cleaned with normal saline, then dressed daily with gauze soaked in honcrivine. Bacterial culture was repeated fortnightly. Antibiotics were administered as dictated by culture and sensitivity report. Wound debridement progressed rapidly and impressively with necrotic and devitalized tissues as well as tenacious pus and fibrin deposits being replaced with healthy granulation tissue. Patients age, sex and bacterial burden did not influence the rate of debridement, rather wound age and necrotic burden were inversely proportional to the debridement rate. Honcrivine did not provoke any inflammatory response nor was any allergic reaction observed. It is one of the oldest remedies known to mankind and is still useful and versatile today as it was 2000 years ago. It is a very effective chemical wound debridant.

Enzymatic debridement is a frequently used technique for removal of necrotic tissue from wounds. Proteases with specificity to break down the collagenous materials in necrotic tissues can achieve selective debridement, digesting denatured collagen in eschar while sparing nonnecrotic tissues. This article provides information about the selectivity of a collagenase-based debriding agent, including evidence of its safe and efficacious uses. Recent research has been conducted, investigating the chemical and biological properties of collagenase ointment, including healing in animal models, digestion power on different collagen types, cell migration activity from collagen degradation products, and compatibility with various wound dressings and metal ions. Evidence presented demonstrates that collagenase ointment is an effective, selective, and safe wound debriding agent.

Burn wound healing is closely associated with the depth of wound and early debridement. The traditional ways of debridement have certain limitations and often result in poor appearance and function of repaired area. At present, the hydrosurgery system has been applied clinically in burn field. This paper summarizes advantages and disadvantages of application of the hydrosurgery system in debridement of burn wound with different depths, different periods, extraordinary region, and uncommon agent.

The burned hand is a common and difficult to care-for entity in the field of burns. Due to the anatomy of the hand (important and delicate structures crowded in a small limited space without sub-dermal soft tissue), surgical debridement of the burned tissue is technically difficult and may cause considerable complications and, therefore, should be performed judiciously. Selective enzymatic debridement of the burn wound can preserve the spontaneous epithelialisation potential and reduce the added injury to the traumatised tissue added by a surgical debridement. The aim of the study was to assess the implication of a selective enzymatic compound (Debrase(®) - Ds) in the special field of deep hand burns, by comparing the actual burn area that required surgical coverage after enzymatic debridement to the burn area clinically judged to require skin grafting prior to debridement. This was a retrospective data collection and analysis from 154 complete files of prospective, open-label study in 275 hospitalised, Ds-treated burn patients. A total of 69 hand burns diagnosed as 'deep' was analysed; 36% of the wounds required surgical intervention after enzymatic debridement; 28.6% of the total burned area estimated initially as deep was covered by skin graft (statistically significant p<0.001). Debridement of deep-hand burns with a selective enzymatic agent decreased the perceived full-thickness wound area and skin-graft use. Copyright © 2011 Elsevier Ltd and ISBI. All rights reserved.

Summary Current surgical and non-surgical eschar removal-debridement techniques are invasive or ineffective. A bromelainbased rapid and selective enzymatic debriding agent was developed to overcome these disadvantages and compared with the standard of care (SOC). The safety and efficacy of a novel Debriding Gel Dressing (DGD) was determined in patients with deep partial and full thickness burns covering up to 67% total body surface area (TBSA). This review summarizes data from seven studies, four of which were randomized clinical trials that included a SOC or control vehicle. DGD eschar debridement efficacy was >90% in all studies, comparable to the SOC and significantly greater than the control vehicle. The total area excised was less in patients treated with DGD compared with the control vehicle (22.9% vs. 73.2%, P<0.001) or the surgical/non-surgical SOC (50.5%, P=0.006). The incidence of surgical debridement in patients treated with DGD was lower than the SOC (40/163 [24.5%] vs. 119/170 [70.0%], P0.001). Less autografting was used in all studies. Long-term scar quality and function were similar in DGD- and SOCtreated. DGD is a safe and effective method of burn debridement that offers an alternative to surgical and non-surgical SOC.

Arthroscopic glenohumeral debridement for symptom control has shown promising short term results in the young active population, when arthroplasty may not be a practical option due to the recommended activity restrictions, potential for complications and/or early wear, and a need for revision. The purpose of this study was twofold: 1) to examine the impact of arthroscopic debridement with or without subacromial decompression on clinical outcomes in patients with severe glenohumeral osteoarthritis (OA), and 2) to explore the differences in post-debridement outcomes between patients who eventually progressed to arthroplasty vs. those who did not. The role of an active worker's compensation claim was examined. Prospectively collected data of patients who were not good candidates for shoulder arthroplasty and had subsequently undergone arthroscopic shoulder debridement were used for analysis. Disability was measured using the relative Constant-Murley score (CMS), the American Shoulder and Elbow Surgeon's (ASES) assessment form, pain free range of motion (ROM), and strength. Fifty-six patients were included in the final analysis. Eighteen (32 %) patients underwent arthroplasty surgery (arthroplasty group) over a period of 11 years. The arthroplasty group was comparable with the non-arthroplasty group prior to debridement but was more disabled at post-debridement surgery follow-up, functioning at less than 50 % of normal based on ASES, relative CMS, and active painfree ROM. In the multivariable analysis, the post-debridement relative CMS was affected by having a compensation claim and having a future arthroplasty. Arthroscopic debridement improved clinical outcome in 68 % of patients suffering from advanced OA of glenohumeral joint. Having less than 50 % of normal score in ASES, relative CMS and painfree ROM post- debridement within a period of two years may be an indication for future arthroplasty. Role of worker's compensation claims should not be underestimated.

Treatment of diabetic foot ulcers includes a number of different regimes such as glycaemic control, re-vascularization, surgical, local wound treatment, offloading and other non-surgical treatments. Although considered the standard of care, the scientific evidence behind the various debridements used is scarce. This presentation will focus on debridement and V.A.C. Therapy, two treatments widely used in patients with diabetes and foot ulcers. A review of existing literature on these treatments in diabetic foot ulcers, with focus on description of the various types of debridements used, the principles behind negative pressure wound therapy (NPWT) using the V.A.C. Therapy system and level of evidence. Five randomized controlled trials (RCT) of debridement were identified; three assessed the effectiveness of a hydrogel as a debridement method, one evaluated surgical debridement and one evaluated larval therapy. Pooling the three hydrogel RCTs suggested that hydrogels are significantly more effective than gauze or standard care in healing diabetic foot ulcers. Surgical debridement and larval therapy showed no significant benefit. Other debridement methods such as enzyme preparations or polysaccharide beads have not been evaluated in RCTs of people with diabetes. More than 300 articles have been published on negative pressure wound therapy, including several small RCTs and a larger multi-centre RCT of diabetic foot ulcers. Negative pressure wound therapy seems to be a safe and effective treatment for complex diabetic foot wounds, and could lead to a higher proportion of healed wounds, faster healing rates, and potentially fewer re-amputations than standard care. Although debridement of the ulcer is considered a prerequisite for healing of diabetic foot ulcers, the grade of evidence is quite low. This may be due to a lack of studies rather than lack of effect. Negative pressure wound therapy seems to be safe and effective in the treatment of some diabetic foot ulcers, although there is still only one well-performed trial that evaluates the effect.

New techniques for wound debridement.

Debridement is a crucial component of wound management. Traditionally, several types of wound debridement techniques have been used in clinical practice such as autolytic, enzymatic, biodebridement, mechanical, conservative sharp and surgical. Various factors determine the method of choice for debridement for a particular wound such as suitability to the patient, the type of wound, its anatomical location and the extent of debridement required. Recently developed products are beginning to challenge traditional techniques that are currently used in wound bed preparation. The purpose of this review was to critically evaluate the current evidence behind the use of these newer techniques in clinical practice. There is some evidence to suggest that low frequency ultrasound therapy may improve healing rates in patients with venous ulcers and diabetic foot ulcers. Hydrosurgery debridement is quick and precise, but the current evidence is limited and further studies are underway. Debridement using a monofilament polyester fibre pad and plasma-mediated bipolar radiofrequency ablation are both very new techniques. The initial evidence is limited, and further studies are warranted to confirm their role in management of chronic wounds. © 2013 The Authors.

Delayed Surgical Debridement and Use of Semiocclusive Dressings for Salvage of Fingers After Purpura Fulminans.

PubMed

Pino, Paula A; Román, Javier A; Fernández, Felipe

2016-12-01

Background: Purpura fulminans is a condition characterized by rapidly evolving skin necrosis and disseminated intravascular coagulation. Early recognition and aggressive supportive management has led to a decrease in its mortality rate, but most of these patients must undergo extensive soft tissue debridement and partial or total limb amputation. There is controversial evidence about the timing of surgery, suggesting that some patients may benefit from delayed debridement with limb preservation. Methods: We present a case of an 86-year-old patient who developed skin necrosis of his four limbs after infectious purpura fulminans. He was treated in the ICU with supportive measures and antibiotic treatment. Surgical debridement was delayed for 4 weeks until necrosis delimitation. Results: Only upper extremity debridement was necessary. Four fingers, including one thumb, were salvaged and successfully treated with semi-occlusive dressing without complications. Conclusion: Early recognition of infectious PF and timely supportive management are important pillars of its treatment. Delayed surgical debridement allows for less aggressive resection and good functional outcome.

Inflammatory and Physiological Consequences of Debridement of Fibrous Tissue after Volumetric Muscle Loss Injury

PubMed Central

Corona, Benjamin T.; Rivera, Jessica C.

2017-01-01

Abstract Volumetric muscle loss (VML) injuries present chronic loss of muscle fibers followed by expansive fibrotic tissue deposition. Regenerative medicine therapies are under development to promote regeneration. However, mitigation of the expansive fibrous tissue is required for integration with the remaining muscle. Using a porcine VML model, delayed debridement of injury fibrosis was performed 3 months post‐VML and observed for an additional 4 weeks. A second group underwent the initial VML and was observed for 4 weeks, allowing comparison of initial fibrosis formation and debrided groups. The following salient observations were made: (i) debridement neither exacerbated nor ameliorated strength deficits; (ii) debridement results in recurrent fibrotic tissue deposition of a similar magnitude and composition as acute VML injury; and (iii) similarly upregulated transcriptional fibrotic and transcriptional pathways persist 4 weeks after initial VML or delayed debridement. This highlights the need for future studies to investigate adjunctive antifibrotic treatments for the fibrosed musculature. PMID:29193769

Routine care of non-healing acute and chronic wounds often comprises either cleaning or debridement. Consequently, debridement is a basic necessity to induce the functional process of tissue repair, which makes it a central medical intervention in the management of acute and chronic, non-healing wounds.

Timing of Operative Debridement in Open Fractures.

2017-01-01

The optimal treatment of open fractures continues to be an area of debate in the orthopedic literature. Recent research has challenged the dictum that open fractures should be debrided within 6 hours of injury. However, the expedient administration of intravenous antibiotics remains of paramount importance in infection prevention. Multiple factors, including fracture severity, thoroughness of debridement, time to initial treatment, and antibiotic administration, among other variables, contribute to the incidence of infection and complicate identifying an optimal time to debridement.

Early postburn debridement of burn blisters is controversial. This study was conducted to compare rates of infection and reepithelialization in debrided vs nondebrided second-degree burns in swine. This was a prospective, blinded, controlled, experimental trial using isoflurane-anesthetized swine. Standardized partial-thickness burns were inflicted by applying an aluminum bar preheated to 80 degrees C to the backs and flanks of two young pigs for 20 seconds. In half of the burns the necrotic epidermis was manually debrided. All burns were randomly treated with octylcyanoacrylate spray (OCA) or dry gauze (C). Full-thickness biopsies were taken at 7, 10, and 14 days for blinded histopathologic evaluation. The primary outcomes were the proportions of infected burns at days 7 and 10 and the proportion of completely reepithelialized burns at day 14. Burns were considered infected in the presence of intradermal neutrophils containing bacteria (intraobserver agreement, K = 1.00). A secondary outcome was the proportion of burns with the presence of scar tissue (abnormal collagen under polarized light; intraobserver correlation, K = 0.93). Chi-square tests were used for group comparisons. This study had 90% power to detect a 40-percentage-point difference in infection rates (alpha = 0.05). A total of 126 biopsies from 42 burns were available for review. Infection rates were higher in the debrided burns both at day 7 (55% vs 4.5%, p < 0.001) and at day 10 (65% vs 9%, p < 0.001) after injury. The proportion of nondebrided burns that were completely reepithelialized was higher at days 10 (68% vs 0%, p < 0.001) and 14 (100% vs 65%, p = 0.003). The presence of scar tissue was more common in debrided burns (75% vs 4.5%, p < 0.001). Burns treated with OCA had fewer infections than controls (4% vs 55%, p < 0.001). Fewer OCA-treated debrided burns were reepithelialized at 14 days than those that were not debrided (30% vs 100%, p = 0.001). Under the current study conditions, early postburn epidermal debridement of second-degree burns resulted in more infections and slower reepithelialization rates in swine. The effects of early postburn epidermal debridement in humans should be explored.

Objectives: The purpose of this systematic review and meta- analysis is to compare clinical results and functional outcomes in patients with osteochondritis dessicans (OCD) lesions of the capitellum treated with either osteochondral autograft transplantation (OATS) or debridement with or without microfracture. Methods: Systematic review of multiple medical databases was performed after PROSPERO registration and using PRISMA guidelines. A literature search was performed using the multiple medical databases and the methodological quality of the individual studies was assessed by two review authors using the Cochrane Collaboration’s “Risk of Bias” tool. Case reports were excluded and only case series of more than five patients and higher level of evidence were included. All study, subject, and surgery parameters were collected. Data was analyzed using statistical software. Odds ratios (OR) were calculated when possible. Data were compared using Pearson Chi-Square and independent sample T tests when applicable. Results: Fifteen studies were included involving 368 patients (326 males and 42 females). There were a total of 197 patients in the debridement group and 171 patients in the OATS group. The mean age was 16.9 +/-4.1 for the debridement group and 14.6 +/-1.2 for the OATS group. Mean follow up was 29.0 +/-24.3 and 38.0 +/-12.8 for the debridement and OATS groups, respectively. Patients that underwent an OATS procedure had a statistically significant improvement in overall arc range of motion compared to patients that had a debridement (P≤0.001). When compared to patients with debridement, patients with OATS were 5.6 times more likely to return to at least their pre-injury level of sports participation (p≤0.002). Conclusion: Post-operative range of motion was significantly improved in patients undergoing an OATS procedure versus a debridement for OCD lesions of the capitellum. Patients with an OATS were 5.7 times more likely to return to at least the pre-injury level of sports participation compared to patients undergoing a debridement. Further studies are necessary in order to directly compare functional outcomes in patients undergoing a debridement procedures versus and OATS procedure.

Chronic wounds, such as venous ulcers, are characterized by physiological impairments manifested by delays in healing, resulting in severe morbidity. Surgical debridement is routinely performed on chronic wounds because it stimulates healing. However, procedures are repeated many times on the same patient because, in contrast to tumor excision, there are no objective biological/molecular markers to guide the extent of debridement. To develop bioassays that can potentially guide surgical debridement, we assessed the pathogenesis of the patients’ wound tissue before and after wound debridement. We obtained biopsies from three patients at two locations, the nonhealing edge (prior to debridement) and the adjacent, nonulcerated skin of the venous ulcers (post debridement), and evaluated their histology, biological response to wounding (migration) and gene expression profile. We found that biopsies from the nonhealing edges exhibit distinct pathogenic morphology (hyperproliferative/hyperkeratotic epidermis; dermal fibrosis; increased procollagen synthesis). Fibroblasts deriving from this location exhibit impaired migration in comparison to the cells from adjacent nonulcerated biopsies, which exhibit normalization of morphology and normal migration capacity. The nonhealing edges have a specific, identifiable, and reproducible gene expression profile. The adjacent nonulcerated biopsies have their own distinctive reproducible gene expression profile, signifying that particular wound areas can be identified by gene expression profiling. We conclude that chronic ulcers contain distinct subpopulations of cells with different capacity to heal and that gene expression profiling can be utilized to identify them. In the future, molecular markers will be developed to identify the nonimpaired tissue, thereby making surgical debridement more accurate and more efficacious. PMID:17515955

Guided surgical debridement: staining tissues with methylene blue.

Precise surgical debridement of wounds is required to achieve wound closure. The authors describe their experience with a technique using topical methylene blue to facilitate precise surgical debridement. In this technique, methylene blue dye is applied topically to the wound surface at the onset of surgery. The stained wound site is then wiped to remove dye from the surface of normal epithelium; eschar, nonviable tissue, and granulation tissue remain stained. The methylene blue-stained tissue is surgically removed, and the newly debrided surface of the wound is assessed for adequate vascularity and biopsied to verify presence of bacteriologic balance before closure. The authors have used this technique in more than 200 wound debridements during the past year, including acute surgical or traumatic wounds, acute and subacute burn wounds, chronic granulating wounds, partially epithelialized wounds, sinus tracts, and fistulae. No adverse reactions have been noted, even on patients undergoing multiple applications through serial operations. Topical application of methylene blue to wounds with mixed tissue content helps to distinguish between viable and nonviable tissue and between epithelialized and nonepithelialized areas, facilitating more precise and complete wound debridement.

The preservation of healthy tissue during surgical debridement is desirable as this may improve clinical outcomes. This study has estimated for the first time the amount of tissue lost during debridement using the VERSAJET system of tangential hydrosurgery. A multicenter, prospective case series was carried out on 47 patients with mixed wound types: 21 (45%) burns, 13 (28%) chronic wounds, and 13 (28%) acute wounds. Overall, 44 (94%) of 47 patients achieved appropriate debridement after a single debridement procedure as verified by an independent photographic assessment. The percentage of necrotic tissue reduced from a median of 50% to 0% (P < 0.001). Median wound area and depth increased by only 0.3 cm (6.8%) and 0.5 mm (25%), respectively. Notably, 43 (91%) of 47 wounds did not progress into a deeper compartment, indicating a high degree of tissue preservation.

Objective: Sternal bone and soft tissue debridement after osteomyelitis of the sternum with simultaneous defect coverage using a vascular pedicle latissimus dorsi flap. Indication: Profound sternal wound healing disorders may be covered with various flap grafts. The latissimus dorsi flap provides a fast, sufficient and reliable option to cover sternal defects. If the bone and soft tissue debridement has been very radical, coverage may be performed in a one-stage procedure. Method: The individual surgical steps for sternal debridement with simultaneous defect coverage using a vascular pedicle latissimus dorsi flap are shown. Conclusion: The radicality of debridement is crucial to treatment success and allows debridement and flap graft coverage to be performed at the same time. If two surgeons work simultaneously, the duration of surgery may be significantly reduced. Georg Thieme Verlag KG Stuttgart · New York.

To evaluate the clinical and microbiological effects of sequential wound debridement in a case series of neuroischaemic diabetic foot ulcers (DFUs) using an ultrasound-assisted wound debridement (UAW) device. A prospective, single-centre study, involving a case series of 24 neuroischaemic DFUs, was conducted to evaluate sequential wound debridement with UAW during a six-week treatment period. Soft tissue punch biopsies were taken every second week of treatment, both before and after wound debridement sessions. Qualitative and quantitative microbiological analysis was performed and wounds were assessed at patient admission, and before and after each debridement procedure. Wound tissue quality scores improved significantly from a mean score of 2.1±1.3 points at patient inclusion, to 5.3±1.7 points (p=0.001). Mean wound sizes were 4.45cm 2 (range: 2-12.25cm 2 ) at week zero, and 2.75cm 2 (range: 1.67-10.70cm 2 ) at week six (p=0.04). The mean number of bacterial species per culture determined at week zero and at week six was 2.53±1.55 and 1.90±1.16, respectively (p=0.023). Wound debridement resulted in significant decreases in bacterial counts (1.17, 1.31 and 0.77 log units in colony forming units (CFU) for week zero, three and six, respectively). The average bacterial load in tissue samples before and after wound debridement after the six-week treatment was Log 5.55±0.91CFU/g and Log 4.59±0.89CFU/g, respectively (p<0.001). The study results showed a significant bacterial load reduction in DFU tissue samples as a result of UAW debridement, independent of bacterial species, some of which exhibited antibiotic-resistance. Significant bacterial load reduction was correlated with improved wound conditions and significant reductions of wound size.

In order to be useful, animal models should be reproducible and consistent regardless of sampling bias, investigator creating burn, and burn location. We determined the variability in burn depth based on biopsy location, burn location and investigator in a porcine model of partial thickness burns. 24 partial thickness burns (2.5 cm by 2.5 cm each) were created on the backs of 2 anesthetized pigs by 2 investigators (one experienced, one inexperienced) using a previously validated model. In one of the pigs, the necrotic epidermis covering each burn was removed. Five full thickness 4mm punch biopsies were obtained 1h after injury from the four corners and center of the burns and stained with Hematoxylin and Eosin and Masson's trichrome for determination of burn depth by a board certified dermatopathologist blinded to burn location and investigator. Comparisons of burn depth by biopsy location, burn location and investigator were performed with t-tests and ANOVA as appropriate. The mean (SD) depth of injury to blood vessels (the main determinant of burn progression) in debrided and non-debrided pigs pooled together was 1.8 (0.3)mm, which included 75% of the dermal depth. Non-debrided burns were 0.24 mm deeper than debrided burns (P<0.001). Burn depth increased marginally from cephalic to caudal in non-debrided burns, but showed no statistical differences for these locations, in debrided burns. Additionally, there were also no statistical differences in burn depths from midline to lateral in either of these burn types. Burn depth was similar for both investigators and among biopsy locations. Burn depth was greater for caudal locations in non-debrided burns and overall non-debrided burns were deeper than debrided burns. However, burn depth did not differ based on investigator, biopsy site, and medial-lateral location. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

Facial gunshot wound debridement: debridement of facial soft tissue gunshot wounds.

Shvyrkov, Michael B

2013-01-01

Over the period 1981-1985 the author treated 1486 patients with facial gunshot wounds sustained in combat in Afghanistan. In the last quarter of 20th century, more powerful and destructive weapons such as M-16 rifles, AK-47 and Kalashnikov submachine guns, became available and a new approach to gunshot wound debridement is required. Modern surgeons have little experience in treatment of such wounds because of rare contact with similar pathology. This article is intended to explore modern wound debridement. The management of 502 isolated soft tissue injuries is presented. Existing principles recommend the sparing of damaged tissues. The author's experience was that tissue sparing lead to a high rate of complications (47.6%). Radical primary surgical debridement (RPSD) of wounds was then adopted with radical excision of necrotic non-viable wound margins containing infection to the point of active capillary bleeding and immediate primary wound closure. After radical debridement wound infection and breakdown decreased by a factor of 10. Plastic operations with local and remote soft tissue were made on 14, 7% of the wounded. Only 0.7% patients required discharge from the army due to facial muscle paralysis and/or facial skin impregnation with particles of gunpowder from mine explosions.

Chronic wounds usually get trapped in the inflammatory stage of wound healing; however, aggressive debridement transforms chronic wounds to acute wounds and therefore complete healing. To investigate healing outcomes and debridement frequency in a large wound data set. Retrospective cohort study. Data collected from 525 wound care centers from June 1, 2008, through June 31, 2012, using a web-based clinical management system. Referred sample of 154 644 patients with 312 744 wounds of all causes (of an initial data set of 364 534 wounds) participated. A total of 47.1% were male. Median age was 69 years (age range, 19-112 years), with 59.2% having one wound. Eligibility criteria included age older than 18 years, receiving at least 1 debridement, and having been discharged from the system. Advanced therapeutic treatment was ineligible. Because of incomplete, questionable, or ineligible data, 57 190 wounds were not included. Most wounds were diabetic foot ulcers (19.0%), venous leg ulcers (26.1%), and pressure ulcers (16.2%). Debridement (removal of necrotic tissue and foreign bodies from the wound) at different frequencies. Wound healing (completely epithelialized with dimensions at 0 × 0 × 0 cm). A total of 70.8% of wounds healed. The median number of debridements was 2 (range, 1-138). Frequent debridement healed more wounds in a shorter time (P <  .001). In regression analysis, significant variables included male sex, physician category, wound type, increased patient age, and increased wound age, area, and depth. The odds ratio varied considerably for each variable. The more frequent the debridements, the better the healing outcome. Although limited by retrospective data, this study's strength was the analysis of the largest wound data set to date.

A chronic ulcer is usually defined as an injury that does not spontaneously evolve towards healing and does not progress through normal healing stages such as inflammation, proliferation and remodelling. This study was designed in order to compare two types of collagenases with mechanical debridement alone. It was thus possible to evaluate their differences in terms of pain and debridement efficacy. Patients were divided into three groups: 30 patients were daily dressed using an ointment based on collagenase produced by Vibrio alginolyticus (B group), 30 patients were daily dressed using an ointment based on a collagenase preparation derived from Clostridium histolyticum (N group) and 30 patients underwent classical mechanical debridement (M group). Complete wound healing over a period of 8 weeks occurred in 24 patients (27%) out of 90;10 patients belonging to the B group, 8 patients to the N group and 6 patients to the M group. This study was performed in order to highlight the differences between two commercially available collagenase-based ointments in comparison with mechanical debridement alone. At the final time point of week, the difference in the percentage of debridement was not statistically significant in all groups, but at 4 weeks, the debrided area in the B group was larger with respect to the N and M groups, suggesting a more rapid wound bed cleansing process. On the basis of our experience, collagenase derived from V. alginolyticus with hyaluronic acid showed chemical and physical properties that make it a product of great manageability and ensure the protection of peri-wound skin. Moreover, less pain was experienced by the patients. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

The Immediate and Delayed Post-Debridement Effects on Tissue Bacterial Wound Counts of Hypochlorous Acid Versus Saline Irrigation in Chronic Wounds.

PubMed

Hiebert, John M; Robson, Martin C

2016-01-01

Introduction: Wound debridement is considered essential in chronic wound management. Hypochlorous acid has been shown to be an effective agent in reducing wound bacterial counts in open wounds. Ultrasound-enabled wound debridement is an effective and efficient method of debridement. This study compared ultrasound irrigation with hypochlorous acid versus saline irrigation for wound debridement on pre- and postoperative wounds and determined regrowth of bacteria over 1 week period of time. Finally, the outcome of definitive wound closure of the clinically clean-appearing wounds was recorded. Methods: Seventeen consenting adult patients with chronic open wounds were randomly selected for study. The patients were randomly divided into the hypochlorous acid irrigation or saline irrigation group. All patients provided pre- and postoperative tissue samples for qualitative and quantitative bacteriology. For the time (7 days) between the debridement procedure and the definitive closure procedure, the wounds were dressed with a silver-impregnated dressing and a hydroconductive dressing. Results : Both types of irrigation in the ultrasonic system initially lowered the bacterial counts by 4 to 6 logs. However, by the time of definitive closure, the saline-irrigated wounds had bacterial counts back up to 10 5 whereas the hypochlorous acid-irrigated wounds remained at 10 2 or fewer. More than 80% of patients in the saline group had postoperative closure failure compared with 25% of patients in the hypochlorous acid group. Conclusions: Hypochlorous acid irrigation with ultrasound debridement reduced bacterial growth in chronic open wounds more efficiently than saline alone. Postoperative wound closure outcomes suggest a remarkable reduction in wound complications after wound debridement using hypochlorous acid irrigation with ultrasound versus saline alone.

Excisional debridement followed by autografting is the standard of care (SOC) for deep burns, but is associated with serious potential complications. Conservative, non-surgical and current enzymatic debridement methods are inefficiently slow. We determined whether a non-surgical option of rapid enzymatic debridement with the debriding enzyme NexoBrid™ (NXB) would reduce need for surgery while achieving similar esthetic and functional outcomes as SOC. We conducted a multi-center, open-label, randomized, controlled clinical trial including patients aged 4-55 years with deep partial and full thickness burns covering 5-30% of their total body surface area (TBSA). Patients were randomly assigned to burn debridement with NXB (applied for 4h) or SOC, which included surgical excisional or non-surgical debridement. NXB significantly reduced the time from injury to complete débridement (2.2 vs. 8.7 days, P<0.0001), need for surgery (24.5% vs. 70.0%, P<0.0001), the area of burns excised (13.1% vs. 56.7%, P<0.0001) and the need for autografting (17.9% vs. 34.1%, P=0.01). Scar quality and quality of life scores were similar in both study groups as were the rates of adverse events. Enzymatic débridement with NXB resulted in reduced need for and extent of surgery compared with SOC while achieving comparable long-term results in patients with deep burns.

Background: Literature on open fracture infections has focused primarily on long bones, with limited guidelines available for open hand fractures. In this study, we systematically review the available hand surgery literature to determine infection rates and the effect of debridement timing and antibiotic administration. Methods: Searches of the MEDLINE, EMBASE, and Cochrane computerized literature databases and manual bibliography searches were performed. Descriptive/quantitative data were extracted, and a meta-analysis of different patient cohorts and treatment modalities was performed to compare infection rates. Results: The initial search yielded 61 references. Twelve articles (4 prospective, 8 retrospective) on open hand fractures were included (1669 open fractures). There were 77 total infections (4.6%): 61 (4.4%) of 1391 patients received preoperative antibiotics and 16 (9.4%) of 171 patients did not receive antibiotics. In 7 studies (1106 open fractures), superficial infections (requiring oral antibiotics only) accounted for 86%, whereas deep infections (requiring operative debridement) accounted for 14%. Debridement within 6 hours of injury (2 studies, 188 fractures) resulted in a 4.2% infection rate, whereas debridement within 12 hours of injury (1 study, 193 fractures) resulted in a 3.6% infection rate. Two studies found no correlation of infection and timing to debridement. Conclusions: Overall, the infection rate after open hand fracture remains relatively low. Correlation does exist between the administration of antibiotics and infection, but the majority of infections can be treated with antibiotics alone. Timing of debridement, has not been shown to alter infection rates. PMID:28344521

Removal of slough and other devitalised tissue is an important step in biofilm-based wound care (BBWC) and wound bed preparation. Debridement is key to management of both slough and biofilm, and a number of methods are available to achieve this, including surgical/sharp and mechanical debridement. Developments have led to products indicated for debridement of wounds, including a sterile pad consisting of monofilament fibres. Our aim is to examine the effectiveness of a monofilament wound debridement pad (WDP), Debrisoft. We assessed the WDP, in laboratory tests, for the removal of mature biofilm from porcine dermal tissue in an ex vivo model, and the clinical management of sloughy wounds that would benefit from debridement. We used the UPPER score to determine the superficial infection status. The WDP was effective in removing biofilm from porcine dermal tissue. A case series of 10 patients with chronic wounds suggested that the WDP was beneficial in the removal of slough. All chronic wounds had slough and were cleaned weekly, for four weeks, using the MDP to achieve improved healing and a clean wound bed. The average wound size decreased from 8.09cm 2 at baseline to 2.3cm 2 at week four, with three wounds healed completely. Exudate was reduced, and the UPPER score improved in every patient. These results indicate that the WDP effectively debrides biofilm and slough, and contributes to care that follows the principles of wound bed preparation and BBWC.

The ever improving health standards in terms of quality and more efficient health care result in an increase in life expectancy, thus increasing the number of elderly people in the population. A higher level of activity in elderly population leads to greater incidence of injuries, and on the other hand, there is an increasing number of comorbidities. Circulatory disorders, diabetes mellitus, metabolic imbalances, etc. and a reduced biological potential of tissue regeneration result in an increased number of chronic wounds that pose a significant health, social and economic burden on the society. These conditions require significant involvement of medical and non-medical staff in pre-hospital institutions. Significant material and other health care resources are allocated for the treatment of chronic wounds. These conditions result in a lower quality of life of patients and their families and caregivers. Debridement is a crucial medical procedure for the treatment of acute and chronic wounds. The result of debridement is removal of all barriers within and around the wound that obstruct physiological processes of wound healing. Debridement is a repeating process when indicated. There are several types of debridement, each with its advantages and disadvantages. The method of debridement should be determined by the physician or other professional trained person on the basis of wound characteristics and in accordance with their expertise and capabilities. In the same wound, we can combine different types of debridement, all with the goal of faster and better wound healing.

Early debridement and/or eschar removal is regarded as a significant step in the treatment of deep partial and full thickness burns. It aims to control wound bioburden and allows early wound closure by conservative treatment or skin grafting. Preservation of viable dermis accompanied by early wound closure, is regarded as a necessary step to reduce scar related complication, e.g. functional limitations and/or unaesthetic scar formation. Aside from the classical techniques of surgical excision as tangential excision for eschar removal, hydro-surgery, maggot therapy, laser, enzymatic debridement have been described as additional techniques in the burn surgeon's armamentarium. It is widely accepted that early eschar removal within 72h improves the outcome of burn wound treatment by reducing bacterial wound colonization, infection and length of hospital stay. In contrast, the right technique for eschar removal is still a matter of debate. There is increasing evidence that enzymatic debridement is a powerful tool to remove eschar in burn wounds, reducing blood loss, the need for autologous skin grafting and the number of wounds requiring surgical excision. In order to assess the role and clinical advantages of enzymatic debridement by a mixture of proteolytic enzymes enriched in Bromelain (Nexobrid ® ) beyond the scope of the literature and in view of users' experience, a European Consensus Meeting was scheduled. The aim was to provide statements for application, based on the mutual experience of applying enzymatic debridement in more than 500 adult and pediatric patients by the consensus panelists. Issues to be addressed were: indications, pain management and anesthesia, timing of application, technique of application, after-intervention care, skin grafting after enzymatic debridement, blood loss, training strategies and learning curve and areas of future research needs. Sixty-eight (68) consensus statements were provided for the use of enzymatic debridement. The degree of consensus was remarkably high, with a unanimous consensus in 88.2% of statements, and lowest degree of consensus of 70% in only 3 statements. This consensus document may serve as preliminary guideline for the use of enzymatic debridement with user-oriented recommendations until further evidence and systematic guidelines are available.

Chemical Debridement of Burns

1974-01-01

The development of effective, non-toxic (local and systemic) methods for the rapid chemical (enzymatic and non-enzymatic) debridement of third degree burns would dramatically reduce the morbidity and mortality of severely burned patients. Sepsis is still the major cause of death of patients with extensive deep burns. The removal of the devitalized tissue, without damage to unburned skin or skin only partially injured by burning, and in ways which would permit immediate (or very prompt) skin grafting, would lessen substantially the problems of sepsis, speed convalescence and the return of these individuals to society as effective human beings, and would decrease deaths. The usefulness and limitations of surgical excision for patients with extensive third degree burns are discussed. Chemical debridement lends itself to complementary use with surgical excision and has the potential advantage over surgical excision in not requiring anesthesia or a formal surgical operation. The authors' work with the chemical debridement of burns, in particular the use of Bromelain, indicates that this approach will likely achieve clinical usefulness. The experimental studies indicate that rapid controlled debridement, with minimal local and systemic toxicity, is possible, and that effective chemotherapeutic agents may be combined with the Bromelain without either interfering with the actions of the other. The authors believe that rapid (hours) debridement accomplished by the combined use of chemical debriding and chemotherapeutic agents will obviate the possibility of any increase in infection, caused by the use of chemical agents for debridement, as reported for Paraenzyme21 and Travase.39,48 It is possible that the short term use of systemic antibiotics begun just before and continued during, and for a short time after, the rapid chemical debridement may prove useful for the prevention of infection, as appears to be the case for abdominal operations of the clean-contaminated and contaminated types.

This study aimed to compare the effect of single-visit full-mouth mechanical debridement (FMD) and quadrant-wise mechanical debridement (QMD) on the levels of serum interleukin (IL)-6, C-reactive protein (CRP) and soluble thrombomodulin. Thirty-six subjects with chronic periodontitis were randomly allocated to three groups: undergoing QMD, single-visit FMD with povidone iodine or with water. Serum IL-6 and soluble thrombomodulin were measured by enzyme-linked immunosorbent assay, and serum CRP was measured by the latex-enhanced nephelometric method. Serum IL-6 level increased significantly immediately after debridement in all the three groups, with this increase being greatest in the full-mouth groups. However, the increase in the full-mouth groups was not significantly higher than that of quadrant-wise group. In the quadrant-wise group, serum IL-6 level decreased significantly 1 month after debridement compared with baseline. Serum-soluble thrombomodulin decreased significantly in the full-mouth groups but not in the quadrant-wise group. Changes in CRP level were not significant at baseline or after debridement in all the three groups. FMD increased serum IL-6 and reduced serum-soluble thrombomodulin to a greater extent than QMD, suggesting that the former technique has stronger transient effects on systemic vascular endothelial functions than the latter.

Coblation technology for surgical wound debridement: principle, experimental data, and technical data.

Debridement is required to prepare the wound bed, essentially in removing undesired tissues observed both in acute wound after burns or trauma and in chronic wounds such as pressure ulcers, leg ulcers, and diabetic foot ulcers. Surgical debridement has been described as one of the most effective methods but can be contraindicated in the elderly, arteriopathic context, or patients under effective anticoagulation. Recently described debridement technologies are based on application of important mechanical severing forces over the wound surface using high-power hydrojets. High water flux acts as a vector for separating necrotic and sloughy tissues from the wound bed and aspirates them out of the wound immediately. Electrical powered techniques and lasers were also scarcely described. The Coblation debridement technology presented here is based on the local induction of a focused plasma field chemically deleting undesired tissues. This technique is a modification of conventional electrosurgical devices, developed in 1928 where tissue excision and coagulation of tissues were observed. Principles of plasma-mediated debridement are based on a bipolar radiofrequency energizing the molecules, thus creating a plasma field. This glow discharge plasma produces chemically active radical species from dissociation of water, breaking molecular bonds, and causing tissue dissolution. The thermal effects are a by-product, which can be modulated by modifying the electrode construction, limiting the local temperature to less than 50°C in order not to induce wound bed renecrosis. The authors describe here the principle, the first technical adaptation for wound debridement, and the potential clinical interest of the Coblation technology.

We wanted to determine if there was a difference in outcome for those patients with Fournier's disease who underwent numerous debridements as opposed to only one initial debridement. The records of 19 patients with the diagnosis of Fournier's gangrene were reviewed retrospectively at our institution. Special attention was placed on demographic data, primary managing service, as well as wound cultures, and the number and timing of surgical debridements. Patients were also classified by a collection of variables at presentation and given a score named the Fournier's Severity Index. We utilised the Fournier's Severity Index (FSI) as developed by Laor et al. which included a number of vital sign data as well as laboratory values collected at admission in the emergency room. The average FSI was 9.1 ranging from 0 to 15. The mean FSI of survivors was 8.6 versus 12.4 of non-survivors. The surgical management of this disease process was also critically examined. The average number of repeated debridements was 3.5 ranging from 1 to 8. Both the FSI and the number of debridements were attempted to be used to predict outcome. Outcome was measured in the variables length of stay (days) and survival. A regression analysis revealed the number of debridements to be positively related to the length of stay (LOS). This was the opposite as expected at the beginning of the study. Also FSI was not predictive of LOS. Fournier's gangrene is a disease process with a wide variability in presentation. The FSI does give some indication about the likelihood of survival based on variables which can be recorded upon presentation. It also provides an efficient way to characterize the acuity of presentation and compare patients. While the repeated nature of debridements may be considered the accepted standard of care in these patients, this was not found to be predictive of outcome.

A Morel-Lavallée lesion is a post-traumatic closed degloving injury of soft tissue. The lesion is due to a shearing trauma with separation of subcutaneous tissue from underlying fascia. When conservative treatment fails, surgical treatment is imperative. Commonly, open drainage and debridement is performed. This case report describes a Morel-Lavallée lesion of the knee in a professional soccer player who was successfully treated with endoscopic debridement and fibrin glue injection after failure of conservative management. This method achieves the goal of an open surgical debridement without exposing patients to an increased morbidity. Copyright © 2016. Published by Elsevier B.V.

The growth and aging of the population of Hawai‘i with a high incidence of diabetes mandates a need for more effective strategies to manage the healing of complicated wounds. Maggot debridement therapy (MDT) is one alternative utilized with successful results. Observations have indicated that maggots have the ability to debride wound beds, provide anti-microbial activity and also stimulate wound healing in diabetic patients. None of the patients refused MDT due to aversion of this treatment modality and the majority of patients had minimal discomfort. In 17 of 23 patients with multiple co-morbidities, the treatment of their complex diabetic wounds by MDT resulted in improvement or cure. Maggot debridement therapy is an effective treatment of diabetic wounds. PMID:22162609

To investigate functional and subjective outcome parameters after arthroscopic debridement of central articular disc lesions (Palmer type 2C) and to correlate these findings with ulna length. Fifty patients (15 men; 35 women; mean age, 47 y) with Palmer type 2C lesions underwent arthroscopic debridement. Nine of these patients (3 men; 6 women; mean static ulnar variance, 2.4 mm; SD, 0.5 mm) later underwent ulnar shortening osteotomy because of persistent pain and had a mean follow-up of 36 months. Mean follow-up was 38 months for patients with debridement only (mean static ulnar variance, 0.5 mm; SD, 1.2 mm). Examination parameters included range of motion, grip and pinch strengths, pain (visual analog scale), and functional outcome scores (Modified Mayo Wrist score [MMWS] and Disabilities of the Arm, Shoulder, and Hand [DASH] questionnaire). Patients who had debridement only reached a DASH questionnaire score of 18 and an MMWS of 89 with significant pain reduction from 7.6 to 2.0 on the visual analog scale. Patients with additional ulnar shortening reached a DASH questionnaire score of 18 and an MMWS of 88, with significant pain reduction from 7.4 to 2.5. Neither surgical treatment compromised grip and pinch strength in comparison with the contralateral side. We identified 1.8 mm or more of positive ulnar variance as an indication for early ulnar shortening in the case of persistent ulnar-sided wrist pain after arthroscopic debridement. Arthroscopic debridement was a sufficient and reliable treatment option for the majority of patients with Palmer type 2C lesions. Because reliable predictors of the necessity for ulnar shortening are lacking, we recommend arthroscopic debridement as a first-line treatment for all triangular fibrocartilage 2C lesions, and, in the presence of persistent ulnar-sided wrist pain, ulnar shortening osteotomy after an interval of 6 months. Ulnar shortening proved to be sufficient and safe for these patients. Patients with persistent ulnar-sided wrist pain after debridement who had preoperative static positive ulnar variance of 1.8 mm or more may be treated by ulnar shortening earlier in order to spare them prolonged symptoms.

Excisional surgical debridement (SD) is still the gold standard in the treatment of deeply burned hands, though the intricate anatomy is easily damaged. Previous studies demonstrated that enzymatic debridement with the bromelain debriding agent NexoBrid ® (EDNX) is more selective and thus can preserve viable tissue with excellent outcome results. So far no method paper has been published presenting different treatment algorithms in this new field. Therefore our aim was to close this gap by presenting our detailed learning curve in EDNX of deeply burned hands. We conducted a single-center prospective observational clinical trial treating 20 patients with deeply burned hands with EDNX. Different anaesthetic procedures, debridement and wound treatment algorithms were compared and main pitfalls described. EDNX was efficient in 90% of the treatments though correct wound bed evaluation was challenging and found unusual compared to SD. Post EDNX surprisingly the majority of the burn surface area was found overestimated (18 wounds). Finally we simplified our process and reduced treatment costs by following a modified treatment algorithm and treating under plexus anaesthesia bedside through a single nurse and one burn surgeon solely. Suprathel ® could be shown to be an appropriate dressing for wound treatment after EDNX. Complete healing (less 5% rest defect) was achieved at an average of day 28. EDNX in deep burned hands is promising regarding handling and duration of the treatment, efficiency and selectivity of debridement, healing potential and early rehabilitation. Following our treatment algorithm EDNX can be performed easily and even without special knowledge in burn wound depth evaluation. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

Although implantation of bone marrow mononuclear cells (BMI) was shown to improve outcomes in patients with severe peripheral arterial occlusive disease (PAOD), little experience has been reported in patients with an arterial occlusion level above the knee, ischemic gangrene, and high cardiovascular risk. This study sought to investigate the timing of gangrene tissue debridement and the safety of BMI in these patients. Six "no-option" PAOD patients were enrolled with an arterial occlusion level above the knee, ischemic gangrene, and 3 systemic diseases related to a high cardiovascular risk. The ischemic status was evaluated by measuring the ankle-brachial index (ABI), transcutaneous oxygen pressure (TcPO2), and wound healing after BMI. All patients safely underwent the procedures with intravenous general anesthesia by titrating propofol. Major lower extremity amputation, minor debridement amputation, and debridement surgery were performed in 2 (33.3%), 1 (16.7%), and 2 (33.3%) patients, respectively, 3.1 2.8 months after BMI. Compared to the amputation group (N=3), the salvage group (N=3) had a significantly higher baseline ABI (P=0.02) and a shorter distance between the gangrene site and arterial occlusion site (P=0.01). In the 3 patients who underwent debridement, ABI and TcPO2 significantly improved 1 month after BMI, and gangrenous tissues were debrided 3.8 ± 3.6 (range, 1~8) months after BMI with complete healing within 1 month. Autologous BMI therapy is safe in patients at high cardiovascular risk with an arterial occlusion level above the knee and ischemic gangrene. Effective predictors of BMI include the baseline ABI and distance to the ischemia. Gangrene tissue should be debrided at least 1 month after BMI.

The basic etiology of neuropathic diabetic foot wounds involves pressure in conjunction with cycles of repetitive stress, leading to failure of skin and soft tissue. The central tenet of any treatment plan addressing neuropathic diabetic foot wounds is the appropriate debridement of nonviable tissue coupled with adequate pressure relief (off-loading). Although numerous advances have been made in the treatment of diabetic foot wounds, including bioengineered tissues, autologous and exogenous cytokine delivery systems, and potentially effective topical antimicrobial modalities, none will succeed without addressing effective debridement and off-loading. Specific debridement and off-loading techniques are discussed, along with available supporting evidence. This includes the use of the "instant" total contact cast, among other modalities.

Complex injuries of the hand remain a therapeutic challenge for surgeons. We present the case of a male who suffered a devastating injury of the hand caused by a conveyor belt. The patient developed a progressive Absidia corymbifera infection of the affected soft tissues. Initial treatments with serial surgical debridement and topical and intravenous itraconazole were unsuccessful in eliminating the infection. We decided to use maggot debridement therapy in a new special design to debride all necrotic, devitalized tissue and preserve only healthy tissue and functioning structures. This maneuverer followed by negative pressure therapy allowed progressive healing. In such complex hand injuries, maggot debridement combined with negative pressure therapy could be considered to achieve effective and considerable results, although future functional morbidity may occur (Fig. 4, Ref. 18).

Design Retrospective review Setting Level I and Level II Trauma Centers Patients/Participants Twenty-nine consecutive patients with high grade open (Gustilo Types II and III) supracondylar femur fractures (OTA/AO 33A and C) treated with debridement and locked plating. Intervention Surgeons at two different Level I trauma centers had different debridement protocols for open supracondylar femur fractures. One center used a More Aggressive (MA)protocol in their patients (n=17) that included removal of all devitalized bone and placement of antibiotic cement spacers to fill large segmental defects. The other center used a Less Aggressive (LA) protocol in their patients (n=12) that included debridement of grossly contaminated bone with retention of other bone fragments and no use of antibiotic cement spacers. All other aspects of the treatment protocol at the two centers were similar: definitive fixation with locked plates in all cases; IV antibiotics were used until definitive wound closure; and weight bearing was advanced upon clinical and radiographic evidence of fracture healing. Main Outcome Measurements Healing after the primary procedure, requirement for secondary bone grafting procedures, and the presence of deep infection. Results Demographics were similar between included patients at each center with regard to: age; gender; rate of open fractures; open fracture classification; mechanism; and smoking (p>.05). Patients at the MA center were more often diabetic (p<.05).Cement spacers to fill segmental defects were used more often after MA debridement (35% vs 0%, p<0.006) and more patients had a plan for staged bone grafting after MA debridement (71% vs 8%, p<0.006). Healing after the index fixation procedure occurred more often after LA debridement (92% vs 35%, p<0.003). There was no difference in infection rate between the two protocols: 25% with the LA protocol; and 18% with the MA protocol, (p=0.63). All patients in both groups eventually healed and were without evidence of infection at an average of 1.8 years of follow-up. Conclusion The degree to which bone should be debrided after a high energy, high grade, open supracondylar femur fracture is a matter of surgeon judgment and falls along a continuous spectrum. Based on the results of the current study, the theoretic tradeoff between infection risk and osseous healing potential, seems to favor a less aggressive approach towards bone debridement in the initial treatment.

Clinical and economic benefit of enzymatic debridement of pressure ulcers compared to autolytic debridement with a hydrogel dressing.

PubMed

Waycaster, Curtis; Milne, Catherine T

2013-07-01

The purpose of this study was to determine the cost-effectiveness of enzymatic debridement using collagenase relative to autolytic debridement with a hydrogel dressing for the treatment of pressure ulcers. A 3-stage Markov model was used to determine the expected costs and outcomes of wound care for collagenase and hydrogel dressings. Outcome data used in the analysis were taken from a randomized clinical trial that directly compared collagenase and hydrogel dressings. The primary outcome in the clinical trial was the proportion of patients achieving a closed epithelialized wound. Transition probabilities for the Markov states were estimated from the clinical trial. A 1-year time horizon was used to determine the expected number of closed wound days and the expected costs for the two alternative debridement therapies. Resource utilization was based on the wound care treatment regimen used in the clinical trial. Resource costs were derived from standard cost references and medical supply wholesalers. The economic perspective taken was that of the long-term care facility. No cost discounting was performed due to the short time horizon of the analysis. A deterministic sensitivity analysis was conducted to analyze economic uncertainty. The number of expected wound days for the collagenase and hydrogel cohorts are estimated at 48 and 147, respectively. The expected direct cost per patient for pressure ulcer care was $2003 for collagenase and $5480 for hydrogel debridement. The number of closed wound days was 1.5-times higher for collagenase (317 vs 218 days) than with the hydrogel. The estimated cost/closed wound day was 4-times higher for the hydrogel ($25) vs collagenase ($6). In this Markov model based on a randomized trial of pressure ulcer care in a long-term care setting collagenase debridement was economically dominant over autolytic debridement, yielding better outcomes at a lower total cost. Since it was a single institution study with a small sample size, the results should be interpreted with caution. Specifically, the findings may not necessarily be generalized to other hydrogel dressings, healthcare settings, age groups, or to wounds of other etiologies.

An overabundance of bacteria in the chronic wound plays a significant role in the decreased ability for primary closure. One means of decreasing the bioburden in a wound is to operatively debride the wound for wound bed optimization prior to application of other therapy, such as Negative Pressure Wound Therapy (NPWT). We undertook a prospective pilot study to assess the efficacy of wound bed preparation for a standard algorithm (sharp surgical debridement followed by NPWT) versus one employing sharp surgical debridement followed by Negative Pressure Wound Therapy with Instillation (NPWTi). Thirteen patients, corresponding to 16 chronic lower leg and foot wounds were taken to the operating room for debridement. The patients were sequentially enrolled in 2 treatment groups: the first receiving treatment with operative debridement followed by 1 week of NPWT with the instillation of quarter strength bleach solution; the other receiving a standard algorithm consisting of operative debridement and 1 week of NPWT. Quantitative cultures were taken pre-operatively after sterile preparation and draping of the wound site (POD # 0, pre-op), post-operatively once debridement was completed (POD # 0, post-op), and on post-operative day 7 after operative debridement (POD # 7, post-op). After operative debridement (post-operative day 0) there was a mean of 3 (±1) types of bacteria per wound. The mean CFU/gram tissue culture was statistically greater - 3.7 × 10(6) (±4 × 10(6)) in the NPWTi group, while in the standard group (NPWT) the mean was 1.8 × 10(6) (±2.36 × 10(6)) CFU/gram tissue culture (p = 0.016); at the end of therapy there was no statistical difference between the two groups (p = 0.44). Wounds treated with NPWTi had a mean of 2.6 × 10(5) (±3 × 10(5)) CFU/gram of tissue culture while wounds treated with NPWT had a mean of 2.79 × 10(6) (±3.18 × 10(6)) CFU/gram of tissue culture (p = 0.43). The mean absolute reduction in bacteria for the NPWTi group was 10.6 × 10(6) bacteria per gram of tissue while there was a mean absolute increase in bacteria for the NPWT group of 28.7 × 10(6) bacteria per gram of tissue, therefore there was a statistically significant reduction in the absolute bioburden in those wounds treated with NPWTi (p = 0.016). It has long been realized that NPWT does not make its greatest impact by bioburden reduction. Other work has demonstrated that debridement alone does not reduce wound bioburden by more than 1 Log. Wounds treated with NPWTi (in this case with quarter strength bleach instillation solution) had a statistically significant reduction in bioburden, while wounds treated with NPWT had an increase in bioburden over the 7 days.

This study assesses the feasibility of using the Versajet™ system (VJS) on an inoculated pork hock (PH) skin surface sequentially for 8 days with daily cleaning and intermediate-level disinfection (ILD). Daily, PHs were inoculated with bacteria suspended in artificial test soil (ATS). An ILD protocol with accelerated hydrogen peroxide (AHP, OxivirTB(®)) was employed to clean and disinfect the VJS between debridements. PH skin contains 6.1-6.8×10(6)cfu/cm(2) bacteria. Bacterial counts in the handpiece and discharge hoses immediately after debridement of the PHs, and before cleaning, increased throughout the study period (5.19-6.43log10cfu/mL). Cleaning with the ILD protocol was reduced bacterial counts on the VJS by 6-log. Protein, a surrogate marker of organic contamination, was also reduced post-cleaning and ILD. Compared to a maximum post-debridement level of protein (57.9 μg/mL) obtained before ILD, VJS protein levels dropped to 9.8 (handpiece) and 13.8 μg/mL (discharge hose). Disinfection of the handpiece and discharge hose after debridement with AHP resulted in a 6-log reduction in bacterial count and 4.2 fold reduction in protein. An ILD protocol with an AHP may be a feasible method for serial skin surface debridements with the VJS for up to eight days. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

Cierny-Mader Type III chronic osteomyelitis: the results of patients treated with debridement, irrigation, vancomycin beads and systemic antibiotics

PubMed Central

Karaduman, Mert

2007-01-01

Cierny-Mader (C-M) Type III osteomyelitis is defined as a localised lesion with both medullary and cortical involvement that is stable mechanically after debridement. The treatment of C-M Type III osteomyelitisis is difficult and requires a precise protocol to achieve a disease-free long-term follow-up. We report here the results of our study on 26 patients (19 men and 7 women; average age: 34.7 years) with C-M Type III osteomylelitis who were treated with radical debridement, irrigation, vancomycin-impregnated custom-made beads and culture-specific systemic antibiotics. Those patients with metaphyseal involvement were treated with deroofing of the cortex and debridement by means of a “trough” (16 patients); those with diaphyseal involvement were treated with both intramedullary reaming and debridement from a trough (ten patients). Antibiotic cement rods were used as an additional therapy in five patients with diaphyseal involvement. Recurrence developed in three patients and was attributed to inadequate debridement; all three patients were treated again in the same manner with success. The mean follow-up is currently 3.6 years (range: 2–6 years). All of the patients have normal clinical, radiographic and laboratory parameters, and all are ambulatory and have returned to their pretreatment level of activity or better. We conclude that C-M Type III chronic osteomyelitis can be safely treated with this protocol. PMID:17375299

Wound excision is the standard treatment for firearm wounds. However, achieving a satisfactory curative effect is difficult because of the traumatic mechanism of high-velocity projectiles. We propose a new therapy by using topical bromelain as a supplement to wound incision for the debridement of firearm wounds. We clarified the debriding effect of bromelain on firearm wounds in pigs. In vitro, muscle tissues around the wound track and normal muscle were incubated in bromelain solutions of different concentrations. Tissue hydrolization was estimated by measuring tissue weight and the release of total amino acids. In vivo, the hind limbs of 15 pigs were wounded with high-velocity projectiles. Five groups were classified as follows: wound excision (E), wound incision (I), bromelain (B), incision + bromelain (IB), and control (C). Debriding effectiveness was estimated using bacterial content, histopathologic examination, and wound healing time. In vitro, hydrolization of wound tissue was significantly more intensive than that of normal tissue. Bromelain solution (10 mg/mL) hydrolyzed wound tissue rapidly with minimal proteolysis of normal tissue. In vivo, the wound-track bacterial content of group IB was similar to that of group E and was significantly lower than that of groups I, B, and C. The wound healing time of group IB was also shorter. Bromelain is effective in the debridement of uncomplicated firearm wounds if used as a supplement to simple wound incision. This new therapy shows notable advantages over conventional surgical debridement as it greatly simplifies the procedures.

To investigate the effect of nicergoline on corneal epithelial wound healing in rats. One hundred Sprague-Dawley male rats were divided into two groups, the control group and the nicergoline-treated group, for 2 weeks. Corneal wound healing was evaluated by fluorescein staining after epithelial debridement. Nerve growth factor (NGF) protein and NGF mRNA were measured in rat corneas by ELISA and RT-PCR. NGF concentration of lacrimal gland was also evaluated by means of ELISA. Immunofluorescent staining was performed in rat corneas. The corneal wound healing rate was increased in nicergoline-treated rats compared with control rats after debridement. Twenty-four hours after epithelial debridement, corneal NGF protein and NGF mRNA levels were higher in the nicergoline-treated group than in the control group. Immunofluorescent staining showed that NGF staining was stronger in nicergoline-treated corneas than in control corneas 24 hours after epithelial debridement. In addition, NGF concentrations in lacrimal glands of the nicergoline-treated group were significantly higher than in the control group 24 hours after epithelial debridement. Nicergoline accelerated wound healing in rat corneas. The promoting effect of nicergoline in corneal wound healing is likely to be related to increased NGF in corneas and lacrimal glands.

Factors associated with infection following open distal radius fractures.

Open fractures are often classified according to a system described by Gustilo and Anderson. However, this system was applied to open long bone fractures, which may not predict the incidence of infection in open metaphyseal fractures of the upper extremity. Other studies have found that wound contamination and systemic illness were the best predictors of infections in open hand fractures. Our study assessed infection in open distal radius fractures and identifies factors that are associated with these infections. We hypothesize that contamination, rather than absolute wound size, is the best predictor of infection associated with open distal radius fractures. A review by CPT code yielded 42 patients with open distal radius fractures between 1997 and 2002 treated at a level one trauma center. Medical records and radiographic follow-up were reviewed to assess the time to irrigation and debridement, the number of debridements in initial treatment period, the method of operative stabilization, the Gustilo and Anderson type of fracture, the Swanson type of fracture, and description of wound contamination. Forty-two patients were followed up for an average of 15 months (range 4 to 68 months). Twenty-four fractures were classified as Gustilo and Anderson type I, ten were type II, and eight were type III, 30 were Swanson type I, and 12 were Swanson type II. Five of the 42 fractures were considered contaminated. Two were exposed to fecal contamination. The others were contaminated with tar, dirt/grass, and gravel, respectively. Three of 42 (7%) fractures developed infections. All three infected cases received a single irrigation and debridement. Two of five contaminated fractures (40%) developed a polymicrobial infection. Both were exposed to fecal contamination and, therefore, considered Swanson type II fractures. They were classified as Gustilo and Anderson type II and IIIB based solely upon the size of the wound. Both required multiple debridements and eventually wrist fusions. The third infection occurred in a Gustilo and Anderson type II and Swanson type I open fracture treated with one debridement and plate fixation. Hardware removal, debridement, and antibiotics resolved the infection. Three contaminated fractures that healed uneventfully received two debridements. Statistical analysis revealed a correlation with infection and contamination (p = 0.0331). The number of initial debridements played a role in infection, but was not statistically significant. No relationship between infection and time to initial irrigation and debridement, method of fixation, Gustilo and Anderson type, or Swanson type was found. We propose that open distal radius fractures behave differently than open long bone fractures. Infection developed in 7% of the distal radius fractures in our study and was significantly associated with wound contamination. We recommend that contamination be included as factor for prognosis in open distal radius fractures. Contaminated fractures should be treated with multiple debridements as part of the initial plan not based upon subsequent development of an infection.

Hyperbaric oxygen therapy (HBOT) concomitant to surgery has been reported to reduce Fournier's gangrene (FG) mortality compared to exclusive surgical debridement. Most report from centers with relatively few patients using only surgical procedure. To assess efficiency of aggressive debridement with adjunctive HBOT. To evaluate Fournier's gangrene severity score index (FGSI) predictive value. 70 Fournier's gangrene (FG) treated by surgical debridement and HBOT. Data were evaluated physical examination findings, admission and final laboratory tests, surgical debridement extent, and antibiotic used. Patients had adjunctive (HBOT). FGSI, developed to assign a score describing the acuity of disease, was used. This index presents patients' vital signs, metabolic parameters (sodium, potassium, creatinine, and bicarbonate levels, and white blood cell count) and computes a score relating to the severity of disease at that time. Data were assessed according to whether the patient survived or died. All patients underwent surgical debridement. Wound debridement was regularly performed in the post operative period. Of 70 patients, 8 died (11.4%) and 62 survived (88.5%). Difference in age between survivors (median age, 50.0 yr) and non survivors (median age, 54.5 yr) was not significant (p=0.321). Median extent of body surface area involved in necrotizing process in patients who survived and did not survive was 2.4% and 4.9%, respectively (p=0.001). Except for albumin, no significant differences were found between survivors and nonsurvivors. Median admission FGSI scores for survivors and non survivors were 2.1±2.0 and 4.2±3.8, (p=0.331). FGSI score did not predict disease severity and the patient's survival. Metabolic aberrations, extent of disease seemed to be important risk factors for predicting FG severity and patient survival.

Studies have demonstrated that conventional chemo-mechanical preparation is limited regarding the decontamination of the endodontic space, which is why alternative techniques such as laser radiation have their importance in the modern endodontic treatment. The present study aims to assess the possibility of improving the debridement of the root canals by removing smear layer using Er: YAG laser radiation. We used 18 extracted teeth, which were subjected to the same initial protocol and then divided into 5 study groups: the control group has not been treated with laser; the other 4 groups were exposed to laser radiation using two different geometries peaks of quartz and two energy levels. Scanning electronic microscopy revealed an increased efficiency in the debridement of all interested areas when using PIPS and XPulse tips at proper energy. In the two groups treated with inferior laser energy, the debridement didn't prove to be superior to the conventional treatment.

Collateral damage-free debridement using 193nm ArF laser

Burn eschar and other necrotic areas of the skin and soft tissue are anhydrous compared to the underlying viable tissue. A 193 nm ArF excimer laser, emitting electromagnetic radiation at 6.4 eV at fluence exceeding the ablation threshold, will debride such necrotic areas. Because such radiation is strongly absorbed by aqueous chloride ions through the nonthermal process of electron photodetachment, debridement will cease when hydrated (with chloride ions) viable tissue is exposed, avoiding collateral damage to this tissue. Such tissue will be sterile and ready for further treatment, such as a wound dressing and/or a skin graft.

Economic Spillovers From Public Investments in Medical Countermeasures: A Case Study of a Burn Debridement Product.

The US federal government invests in the development of medical countermeasures for addressing adverse health effects to the civilian population from chemical, biological, and radiological or nuclear threats. We model the potential economic spillover effects in day-to-day burn care for a federal investment in a burn debridement product for responding to an improvised nuclear device. We identify and assess 4 primary components for projecting the potential economic spillover benefits of a burn debridement product: (1) market size, (2) clinical effectiveness and cost-effectiveness, (3) product cost, and (4) market adoption rates. Primary data sources were the American Burn Association's 2015 National Burn Repository Annual Report of Data and published clinical studies used to gain European approval for the burn debridement product. The study results showed that if approved for use in the United States, the burn debridement product has potential economic spillover benefits exceeding the federal government's initial investment of $24 million a few years after introduction into the burn care market. Economic spillover analyses can help to inform the prioritizing of scarce resources for research and development of medical countermeasures by the federal government. Future federal medical countermeasure research and development investments could incorporate economic spillover analysis to assess investment options.

2013-01-01

Maggot debridement therapy (MDT) is an established method of debridement of nonhealing wounds. Despite intense clinical research about its efficacy and effects of substances produced by the larvae, growth and development of maggots in the wounds remain largely unexplored. In the present study, the bags with larvae (n = 52), which had been used to debride traumatic, ischemic, diabetic and venous ulcers, were collected and examined. Survival, length, width and larval instar of the maggots within each bag were recorded and analyzed with respect to the wound type and duration of the treatment. Survival of maggots after a 48-h cycle of MDT ranged between 63.6 and 82.7%. Maggots in venous ulcers had on average 9-19% higher mortality than maggots within traumatic, ischemic, and diabetic ulcers. Length of larvae after 48 h cycle of MDT reached on average 7.09-9.68 mm, and average width varied between 1.77 and 2.26 mm. Larvae in venous ulcers were significantly smaller after 48 h, but not after 72 h treatment compared to the other wound types. Further studies should be aimed to identify other patient-associated factors which might influence growth and survival of the larvae during maggot debridement therapy.

Methylene Blue-Guided Debridement as an Intraoperative Adjunct for the Surgical Treatment of Periprosthetic Joint Infection.

2017-12-01

Current methods to identify infected tissue in periprosthetic joint infection (PJI) are inadequate. The purpose of this study was (1) to assess methylene blue-guided surgical debridement as a novel technique in PJI using quantitative microbiology and (2) to evaluate clinical success based on eradication of infection and infection-free survival. Sixteen total knee arthroplasty patients meeting Musculoskeletal Infection Society criteria for PJI undergoing the first stage of 2-stage exchange arthroplasty were included in this prospective study. Dilute methylene blue (0.1%) was instilled in the knee before debridement, residual dye was removed, and stained tissue was debrided. Paired tissue samples, stained and unstained, were collected from the femur, tibia, and capsule during debridement. Samples were analyzed by neutrophil count, semiquantitative culture, and quantitative polymerase chain reaction (PCR). Clinical success was a secondary outcome. The mean age was 64.0 ± 6.0 years, and follow-up was 24.4 ± 3.5 months. More bacteria were found in methylene blue-stained vs unstained tissue-based on semiquantitative culture (P = .001). PCR for staphylococcal species showed 9-fold greater bioburden in methylene blue-stained vs unstained tissue (P = .02). Tissue pathology found 53 ± 46 polymorphonuclear leukocytes per high-power field in methylene blue-stained vs 4 ± 13 in unstained tissue (P = .0001). All subjects cleared their primary infection and underwent reimplantation. At mean 2-year follow-up, 25% of patients failed secondary to new infection with a different organism. These results suggest a role for methylene blue in providing a visual index of surgical debridement in the treatment of PJI. Copyright © 2017 Elsevier Inc. All rights reserved.

Good quality of life outcomes after treatment of prosthetic joint infection with debridement and prosthesis retention.

2016-05-01

Patients treated for early prosthetic joint infection (PJI) with surgical debridement and prosthesis retention have a rate of successful infection eradication that is similar to patients treated with the traditional approach of prosthesis exchange. It is therefore important to consider other outcomes after prosthetic joint infection treatment that may influence management decisions, such as quality of life (QOL). Our aim was to describe infection cure rates and quality of life for patients with prosthetic joint infection treated with debridement and prosthesis retention and to determine if treatment with this approach was a risk factor for poor quality of life outcomes. Prospectively collected pre and post-arthroplasty data were available for 2,134 patients, of which PJI occurred in 41. For patients treated for prosthetic joint infection, the 2-year survival free of treatment failure was 87% (95%CI 84-89). Prosthetic joint infection cases treated with debridement and retention had a similar improvement from pre-arthroplasty to 12-months post-arthroplasty as patients without PJI in QOL according to the SF-12 survey. Prosthetic joint infection treated with debridement and retention was not a risk factor for poor quality of life on univariate or multivariate analysis. Prosthetic joint infection treated with debridement and prosthesis retention results in good cure rates and quality of life. Further studies are required that directly compare quality of life for different surgical approaches for prosthetic joint infection to better inform management decisions. © 2015 Orthopaedic Research Society.

OBJECTIVE Post craniotomy infections have generally been treated by debridement of infected tissues, disposal of the bone flap, and delayed cranioplasty several months later to repair the resulting skull defect. Debridement followed by retention of the bone flap has also been advocated. Here we propose an alternative operative strategy for the treatment of post craniotomy infections. METHODS Two patients presenting with clinical and radiographic signs and symptoms of post craniotomy infections were treated by debridement, bone flap disposal, and immediate titanium mesh cranioplasty. The patients were subsequently administered antibiotics and their clinical courses were followed. RESULTS The patients treated in this fashion did not have recurrence of their infections during three-year follow-up periods. CONCLUSIONS Surgical debridement, bone flap disposal and immediate titanium mesh cranioplasty may be a suitable option for the treatment of post craniotomy infections. This treatment strategy facilitates the eradication of infectious sources and obviates the risks and costs associated with a second surgical procedure. PMID:22120410

Debridement, the removal of diseased, nonviable tissue, is critical for clinicians to readily assess wound status and prepare the wound bed for advanced therapeutics or downstream active healing. Removing necrotic slough and eschar through surgical or mechanical methods is less specific and may be painful for patients. Enzymatic debridement agents, such as Clostridial collagenase, selectively and painlessly degrade devitalized tissue. In addition to its debriding activities, highly-purified Clostridial collagenase actively promotes healing, and our past studies reveal that extracellular matrices digested with this enzyme yield peptides that activate cellular migratory, proliferative and angiogenic responses to injury in vitro, and promote wound closure in vivo. Intriguingly, while collagenase Santyl® ointment, a sterile preparation containing Clostridial collagenases and other non-specific proteases, is a well-accepted enzymatic debridement agent, its role as an active healing entity has never been established. Based on our previous studies of pure Clostridial collagenase, we now ask whether the mixture of enzymes contained within Santyl® produces matrix-derived peptides that promote cellular injury responses in vitro and stimulate wound closure in vivo. Here, we identify novel collagen fragments, along with collagen-associated peptides derived from thrombospondin-1, multimerin-1, fibronectin, TGFβ-induced protein ig-h3 and tenascin-C, generated from Santyl® collagenase-digested human dermal capillary endothelial and fibroblastic matrices, which increase cell proliferation and angiogenic remodeling in vitro by 50-100% over controls. Using an established model of impaired healing, we further demonstrate a specific dose of collagenase from Santyl® ointment, as well as the newly-identified and chemically-synthesized ECM-derived peptides significantly increase wound re-epithelialization by 60-100% over saline-treated controls. These results not only confirm and extend our earlier studies using purified collagenase- and matrix-derived peptides to stimulate healing in vitro and in vivo, but these Santyl®-generated, matrix-derived peptides may also represent exciting new opportunities for creating advanced wound healing therapies that are enabled by enzymatic debridement and potentially go beyond debridement.

Root canal debridement: an online study guide.

PubMed

2008-05-01

The Editorial Board of the Journal of Endodontics has developed a literature-based study guide of topical areas related to endodontics. This study guide is intended to give the reader a focused review of the essential endodontic literature and does not cite all possible articles related to each topic. Although citing all articles would be comprehensive, it would defeat the idea of a study guide. This section will present root canal debridement including subdivisions on canal access, canal debridement, orifice enlargement and preflaring, crown-down technique, balanced force, nickel titanium and other shape memory alloys, rotary engine-driven techniques, endodontic instruments, irrigation, electronic apex locators, sonics/ultrasonics, smear layer, and intracanal medicaments.

AIM: To determine the significance of enterostomy in the emergency management of Fournier gangrene. METHODS: The clinical data of 51 patients (49 men and 2 women) with Fournier gangrene who were treated at our hospital over the past 12 years were retrospectively analyzed. The patients were divided into two groups according the surgical technique performed: enterostomy combined with debridement (the enterostomy group, n = 28) or debridement alone (the control group, n = 23). Patients in the enterostomy group received thorough debridement during surgery and adequate local drainage after surgery, as well as administration of broad-spectrum antibiotics. The clinical data and outcomes in both groups were analyzed. RESULTS: The surgical procedures were successful in both patient groups. In the enterostomy group, 10 (35.8%) patients required skin grafting with a total of six debridement procedures. While in the control group, six (26.1%) patients required four debridement procedures. However, this difference was not statistically significant. Following surgery, the time to normal body temperature (6 d vs 8 d, P < 0.05) and average length of hospital stay (14.3 ± 7.8 d vs 20.1 ± 8.9 d, P < 0.05) were shorter in the enterostomy group. The case fatality rate was lower in the enterostomy group than that in the control group (3.6% vs 21.7%, P < 0.05). CONCLUSION: Enterostomy can decrease the case fatality rate of patients with Fournier gangrene. PMID:24976731

To review the efficacy of a treatment approach for patients with infection and colonized implants after open reduction and internal fixation of fractures. Retrospective case series. Level one trauma center. Twenty patients were treated for wound infection with colonized implants after open reduction and internal fixation. Surgical debridement, removal of implants, and a short postoperative oral antibiotic course. The course of patients after surgical debridement and removal of implants, including culture results, antibiotic administration, and presence of recurrent clinical infection and radiographic union. Twenty patients had clinical presentations, including skin breakdown, serous drainage, purulent drainage and/or exposed implants, most commonly of the tibia (15 of 20). Mean time from index procedure to debridement with implant removal was 19.7 months. At the time of debridement and implant removal, 18 of 20 (90%) patients had a positive intraoperative culture (16 routine cultures and 2 broth cultures). The most common bacteria were Enterobacter cloacae (5/17) and methicillin-sensitive Staphylococcus aureus (4/17). All patients had soft tissue healing without signs of recurrent infection after mean follow up of 40 months after implant removal. Surgical debridement with implant removal plus a short oral antibiotic course is effective to resolve wound infection with a colonized implant in the setting of healed fracture after internal fixation. Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Debridement Techniques in Pediatric Trauma and Burn-Related Wounds

Block, Lisa; King, Timothy W.; Gosain, Ankush

2015-01-01

Significance: Traumatic injuries are the leading cause of morbidity and mortality in children. The purpose of this review is to provide an overview of the initial assessment and management of traumatic and burn wounds in children. Special attention is given to wound cleansing, debridement techniques, and considerations for pain management and psychosocial support for children and families. Recent Advances: Basic and translational research over the last 5–7 years has advanced our knowledge related to the optimal care of acute pediatric traumatic and burn wounds. Data concerning methods, volume, solution and timing for irrigation of acute traumatic wounds, timing and methods of wound debridement, including hydrosurgery and plasma knife coblation, and wound dressings are presented. Additionally, data concerning the long-term psychosocial outcomes following acute injury are presented. Critical Issues: The care of pediatric trauma and burn-related wounds requires prompt assessment, pain control, cleansing, debridement, application of appropriate dressings, and close follow-up. Ideally, a knowledgeable multidisciplinary team cares for these patients. A limitation in the care of these patients is the relative paucity of data specific to the care of acute traumatic wounds in the pediatric population. Future Directions: Research is ongoing in the arenas of new debridement techniques and instruments, and in wound dressing technology. Dedicated research on these topics in the pediatric population will serve to strengthen and advance the care of pediatric patients with acute traumatic and burn wounds. PMID:26487978

Propeller flap for treatment of a poststernotomy sternal fistula: a case report.

PubMed

Corradino, Bartolo; Di Lorenzo, Sara; Hubova, Martina; Cordova, Adriana

2014-11-01

The treatment of post-operative deep sternal wound infections is a real challenge for surgeons. Conservative treatment with debridement and vacuum-assisted closure (VAC) therapy is not always successful. In the most severe and chronic cases, a surgical debridement and reconstruction of the defect is mandatory. In this report, the authors present a case of a 61-year-old female patient with a chronic cutaneous fistula in the sternal region following a median sternotomy after coronary artery bypass. The patient had already undergone treatment with antibiotics, drainage of an abscess and local debridement, but the infection continued to relapse periodically. The authors decided to treat the fistula with debridement and reconstruction with a local freestyle propeller flap mobilised from the right parasternal region. The fistula healed without any complications. There has been no relapse, and the aesthetic result is satisfactory. The scar at the donor site is acceptable with a minimum alteration to the mammary region. Sternal fistulas after medial sternotomy are difficult to treat. The treatment method of debridement followed, in certain cases, by VAC therapy is quite controversial. A surgical procedure is sometimes necessary to speed healing. Mobilisation of a freestyle propeller flap represents a less invasive surgical approach to the treatment of sternal fistulas in cases of conservative treatment failure.

Arthroscopic debridement has been used to treat patients with degenerative knee osteoarthritis, although there is sometimes conflicting evidence documenting its efficacy. This study evaluates the success of arthroscopic debridement in elderly patients with grade III and IV chondromalacia of the knee as measured by patient satisfaction and the need for additional surgery. From December 1998 to August 2001, a total of 102 consecutive cases of knee arthroscopy in 99 patients > 60 years were performed. Average follow-up was 34 months (range: 7-104 months). Patients were asked about their satisfaction using a visual analog scale, and the presence of meniscal lesions during arthroscopy and the treatment for these lesions were evaluated. Knees also were assessed for articular surface degeneration using Outerbridge's classification for chondromalacia. The need for and type of additional surgery was evaluated. During arthroscopy, meniscal lesions requiring a partial meniscectomy were found in 95 knees. Chondromalacia was found in 92 knees; 53 knees had grade I or II chondromalacia and 39 knees had grade III or IV chondromalacia. Additional surgery was performed in 17 knees. Mean patient satisfaction score was 73 (range: 50-100) in the 39 knees with grade III or IV chondromalacia after arthroscopic debridement was performed. These findings suggest arthroscopic debridement in elderly patients has a place in the treatment algorithm for grade III or IV chondromalacia of the knee.

This study evaluates the effect on post space debridement in oval-shaped canals of an experimental ultrasonic tip with oval section (Satelec) compared with a circular ultrasonic tip (KaVo). Thirty teeth with an oval-shaped canal were endodontically treated and obturated and then randomly divided into 3 groups (n = 10) according to the procedure used for post space debridement: Satelec tip, Largo #2 drill + KaVo file, and Largo #2 drill + water. Debris and dentin tubules were evaluated by assigning scores to scanning electron microscope post spaces images; lower scores corresponded to fewer debris and higher number of open tubules. The Satelec group showed significantly lower debris and open tubules scores than KaVo group (p < .05) and control group (p < .05), which differed significantly between each other (p < .05). Also the debris and open tubules scores in different post space regions differed significantly among the experimental groups (p < .001). The oval ultrasonic tip resulted in a better post space debridement than a circular ultrasonic tip in oval-shaped canals.

Management of civilian ballistic fractures.

Seng, V S; Masquelet, A C

The management of ballistic fractures, which are open fractures, has often been studied in wartime and has benefited from the principles of military surgery with debridement and lavage, and the use of external fixation for bone stabilization. In civilian practice, bone stabilization of these fractures is different and is not performed by external fixation. Fifteen civilian ballistic fractures, Gustilo II or IIIa, two associated with nerve damage and none with vascular damage, were reviewed. After debridement and lavage, ten internal fixations and five conservative treatments were used. No superficial or deep surgical site infection was noted. Fourteen of the 15 fractures (93%) healed without reoperation. Eleven of the 15 patients (73%) regained normal function. Ballistic fractures have a bad reputation due to their many complications, including infections. In civilian practice, the use of internal fixation is not responsible for excessive morbidity, provided debridement and lavage are performed. Civilian ballistic fractures, when they are caused by low-velocity firearms, differ from military ballistic fractures. Although the principle of surgical debridement and lavage remains the same, bone stabilization is different and is similar to conventional open fractures. Copyright © 2013 Elsevier Masson SAS.

Necrotizing fasciitis (NF) is a life-threatening situation that is rare in children, especially infants, and early diagnosis is challenging. Timely identification and broad-spectrum antibiotic and supportive treatment before surgical debridement are very important for survival and may reduce scar formation. A previously healthy 4-month-old infant was admitted to our pediatric intensive care unit (PICU) with a history of fever and cough for 5 days and extreme swelling of the scrotum for one day. Necrotic-like tissue without margins appeared on his scrotum and perineum in 24 hours. NF was suspected, and the patient soon developed shock. The patient underwent surgical debridement after his condition stabilized. Pathological analysis confirmed the diagnosis of NF. Broad-spectrum antibiotic, immediate fluid resuscitation, assistant ventilation, and vasoactive drugs were administered. Surgical debridement and autologous split-thickness skin grafting were performed. The wound recovered well after 2 months. Ultrasound revealed normal testicles, and no anorectal injury was found. Close clinical monitoring and timely treatment of skin injuries in sick children are very important. Sufficient antibiotic administration and supportive treatment before surgical debridement are crucial for survival from NF.

Pelvic fixation with S2-alar-iliac (S2AI) screws can increase the rigidity of a lumbosacral construct, which may promote bone healing, improve antibiotic delivery to infected tissues, and avoid L5-S1 pseudarthrosis. To describe the use of single-stage posterior fixation without debridement for the treatment of pyogenic vertebral diskitis and osteomyelitis (PVDO) at the lumbosacral junction. Technical report. We describe the management of PVDO at the lumbosacral junction in which the infection invaded the endplates, disk space, vertebrae, prevertebral soft tissues, and epidural space. Pedicle involvement precluded screw fixation at L5. Surgical management consisted of a single-stage posterior operation with rigid lumbopelvic fixation augmented with S2-alar-iliac screws and without formal debridement of the infected area, followed by long-term antibiotic treatment. At 2-year follow-up, successful fusion and eradication of the infection were achieved. PVDO at the lumbosacral junction may be treated successfully using rigid posterior-only fixation without formal debridement combined with antibiotic therapy.

Wound debridement is essential for the removal of necrotic or nonviable tissue from the wound surface to create an environment conducive to healing. Nonsurgical enzymatic debridement is an attractive method due to its effectiveness and ease of use. Papain is a proteolytic enzyme derived from the fruit of Carica papaya and is capable of breaking down a variety of necrotic tissue substrates. The present study was focused on the use of gamma radiation for sterilization of papain dressing with wound debriding activity. Membranes with papain were prepared using 0.5% chitin in lithium chloride/dimethylacetamide solvent and sterilized by gamma radiation. Fluid absorption capacity of chitin-papain membranes without glycerol was 14.30±6.57% in 6 h. Incorporation of glycerol resulted in significant (p<0.001) increase in the absorption capacity. Moisture vapour transmission rate of the membranes was 4285.77±455.61 g/m2/24 h at 24 h. Gamma irradiation at 25 kGy was found suitable for sterilization of the dressings. Infrared (IR) spectral scanning has shown that papain was stable on gamma irradiation at 25-35 kGy. The irradiated chitin-papain membranes were impermeable to different bacterial strains and also exhibited strong bactericidal action against both Gram-positive and Gram-negative bacteria. The fluid handling characteristics and the antimicrobial properties of chitin-papain membranes sterilized by gamma radiation were found suitable for use as wound dressing with debriding activity.

The aim of this study was to compare the three different treatment methods and investigate The effectiveness of the therapeutic effect of common salt. This retrospective study involved patients who were treated in our clinic for umbilical pilonidal sinus disease between January 2010 and December 2011. The patients were divided to three subgroups according to treatment methods. Group I: Cases treated with only local debridement and systemic antibiotic, group II: cases treated with local debridement, systemic antibiotic and silver nitrate, group 3: cases treated with debridement, systemic antibiotic and salt. In this study, 63 patients with the diagnosis of UPS were treated in our clinic. The patients were classified into three groups; group I included 20 patients, group II included 18 patients and group III included 18 patients. During 16-24 months of follow-up, 4 (20%) recurrences in group1 and 2 (11.1%) recurrences in group 2 were detected. Recurrence rate of group 3 was significantly different (5.55%) when compared to group 2. The mean period for returning to daily activities and work was 1 day for the patients. In conclusion, we suggest that pilonidal sinus cases which are not complicated by abcess and cellulitis can be treated by local removal of umbilical hairs, debridement and dressing without surgery. We conclude that application of common salt (table/ cooking salt) to umbilical pilonidal sinus with granuloma is a simple and highly effective way of treatment without any relapse and complications.

This study examined the efficacy of bedside surgical debridement in a nursing home population. A retrospective chart review was performed of sacrum, sacrococcyx, coccyx, ischium, and trochanter (SSCIT) region pressure injuries in the Skilled Wound Care practice (Los Angeles, CA). The patient population was refined from 2128 to 227 patients visited 8 or more times during nursing home stays found to have 1 or more SSCIT pressure injuries. Of the 227 patients, there were approximately 319 individual SSCIT wounds, with an average of 1.4 SSCIT wounds per patient. Bedside surgical debridement was performed using a sharp excisional technique on 190 of 319 (59.5%) SSCIT wounds. An analysis of the square surface area of the 190 debrided wound sites revealed a mean ulcer surface area of 20.76 cm2. Of those 190 wound sites, 138 (73%) had a reduction in square surface area, and 52 (27%) had no change or an increase in square surface area and were categorized as nonresponders. Of the wounds that did improve by a reduction in wound surface area, the average wound surface area reduction was 6.81 cm2 at 4 weeks (25%), 8.91 cm2 reduction at 8 weeks (33%), and 10.87 cm2 reduction at 12 weeks (40%). From the 190 wound sites, there were a total of 43 (23%) wounds that had a square surface area of 0 (reepithelialized), which has a healing rate of 23%. Traditional bedside debridement provides excellent results in reducing the square surface area for a majority of wounds. Whether used alone or as an adjunct to any treatment plan, the use of surgical sharp equipment aids in achieving good wound healing and advancing the rate of wound closure. Although wound healing requires many components, sharp debridement can effectively remove devitalized tissue and is a proven significant component to advancing wound closure.

Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tuberculosis. However, high risk of structural damage might relate with anterior surgery, such as damage in lungs, heart, kidney, ureter and bowel, and the deformity correction is also limited. Due to the organs are in the front of spine, there are less complications in posterior approach. Spinal pedicle screw passes through the spinal three-column structure, which provides more powerful orthopedic forces compared with the vertebral body screw, and the kyphotic deformity correction effect is better in posterior approach. In this paper, we report a 68-year-old male patient with thoracic tuberculosis who underwent surgical treatment by debridement, interbody fusion and internal fixation via posterior approach only. The patient was placed in prone position under general anesthesia. Posterior midline incision was performed, and the posterior spinal construction was exposed. Then place pedicle screw, and fix one side rod temporarily. Make the side of more bone destruction and larger abscess as lesion debridement side. Resect the unilateral facet joint, and retain contralateral structure integrity. Protect the spinal cord, nerve root. Clear sequestrum, necrotic tissue, abscess of paravertebral and intervertebral space. Specially designed titanium mesh cages or bone blocks were implanted into interbody. Fix both side rods and compress both sides to make the mesh cages and bone blocks tight. Reconstruct posterior column structure with allogeneic bone and autologous bone. Using this technique, the procedures of debridement, spinal cord decompression, deformity correction, bone grafting, and internal fixation can be completed with only one incision and surgical position, and the deformity correction efficiency is higher than anterior surgery. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

The purpose of this study was to determine the cost effectiveness (from a payer's perspective) of adding clostridial collagenase ointment (CCO) to selective debridement compared with selective debridement alone (non-CCO) in the treatment of stage IV pressure ulcers among patients identified from the US Wound Registry. A 3-state Markov model was developed to determine costs and outcomes between the CCO and non-CCO groups over a 2-year time horizon. Outcome data were derived from a retrospective clinical study and included the proportion of pressure ulcers that were closed (epithelialized) over 2 years and the time to wound closure. Transition probabilities for the Markov states were estimated from the clinical study. In the Markov model, the clinical outcome is presented as ulcer-free weeks, which represents the time the wound is in the epithelialized state. Costs for each 4-week cycle were based on frequencies of clinic visits, debridement, and CCO application rates from the clinical study. The final model outputs were cumulative costs (in US dollars), clinical outcome (ulcer-free weeks), and incremental cost-effectiveness ratio (ICER) at 2 years. Compared with the non-CCO group, the CCO group incurred lower costs ($11,151 vs $17,596) and greater benefits (33.9 vs 16.8 ulcer-free weeks), resulting in an economically dominant ICER of -$375 per ulcer. Thus, for each additional ulcer-free week that can be gained, there is a concurrent cost savings of $375 if CCO treatment is selected. Over a 2-year period, an additional 17.2 ulcer-free weeks can be gained with concurrent cost savings of $6,445 for each patient. In this Markov model based on real-world data from the US Wound Registry, the addition of CCO to selective debridement in the treatment of pressure ulcers was economically dominant over selective debridement alone, resulting in greater benefit to the patient at lower cost.

Recent introduction of rapid bromelain-based enzymatic debridement has been increasingly popular in its use in non-surgical debridement in deep partial and full thickness burns. We designed this study to evaluate the evidence suggested by current studies on the perceived benefits of using Nexobrid® as compared to traditional surgical standard of care (SOC) in burns wound debridement. A comprehensive search on electronic databases Pubmed, Embase and Web of Science was done to identify studies published between 1986 to 2017 involving the use of Nexobrid in deep partial and full thickness burns. Studies were evaluated for proposed benefits and categorised under supporting evidence, contradicting evidence and anecdotal opinions. 7 well designed prospective studies met the inclusion comprising of 4 randomised controlled trials. 6 proposed benefits associated with the use of Nexobrid were extracted including reduced time to complete debridement, need for surgery, area of burns excised, need for autograft, time to wound closure and improved scar quality. Most proposed benefits have strong supporting evidences with minimal anecdotal opinions from controlled trials except the proposed improvement in scar quality and reduced time to wound healing that had at least 3 refuting evidence and 1 anecdotal evidence. Incidence of pain was also evaluated and were mainly anecdotal lacking formal objective assessment or cohort study. Despite the lack of literatures available, the benefits of Nexobrid is evident in published randomised and single arm studies. Large number of studies are needed to aid further evaluating the proposed benefits of Nexobrid.

To develop methods to compare carbon dioxide (CO2) resurfacing lasers, fluence, and debridement effects on tissue shrinkage and histological thermal denaturation. In vitro human or in vivo porcine skin samples received up to 5 passes with scanner or short-pulsed CO2 resurfacing lasers. Fluences ranging from 2.19 to 17.58 J/cm2 (scanner) and 1.11 to 5.56 J/cm2 (short pulsed) were used to determine each laser's threshold energy for clinical effect. Variable amounts of debridement were also studied. Tissue shrinkage was evaluated by using digital photography to measure linear distance change of the treated tissue. Tissue histological studies were evaluated using quantitative computer image analysis. Fluence-independent in vitro tissue shrinkage was seen with the scanned and short-pulsed lasers above threshold fluence levels of 5.9 and 2.5 J/cm2, respectively. Histologically, fluence-independent thermal depths of damage of 77 microns (scanner) and 25 microns (pulsed) were observed. Aggressive debridement of the tissue increased the shrinkage per pass of the laser, and decreased the fluence required for the threshold effect. In vivo experiments confirmed the in vitro results, although the in vivo threshold fluence level was slightly higher and the shrinkage obtained was slightly lower per pass. Our methods allow comparison of different resurfacing lasers' acute effects. We found equivalent laser tissue effects using lower fluences than those currently accepted clinically. This suggests that the morbidity associated with CO2 laser resurfacing may be minimized by lowering levels of tissue input energy and controlling for tissue debridement.

The goal in treating refractory periodontitis (RP) is to arrest or slow disease progression, which usually has included the use of systemic antibiotics adjunct to conventional mechanical debridement. The aim of this systematic review was to evaluate the evidence that the association of systemic antibiotics with conventional mechanical debridement increases the efficacy of periodontal therapy in the treatment of RP. The authors searched for studies in PubMed MEDLINE, Cochrane Central Register of Controlled Trials, Thomson Reuters Web of Science, Scopus, Latin American and Caribbean Center on Health Sciences Information, and Scientific Electronic Library Online electronic databases by using selected key words from the earliest records up through October 31, 2014. Only clinical intervention studies in which investigators compared the treatment of participants with RP with either mechanical debridement alone or associated with systemic antibiotics were eligible for selection. Two authors independently assessed the risk of bias of each selected study. The authors identified 13 articles and included 6 of them. Investigators in all studies reported greater reductions in probing depth or in loss of clinical attachment level after adjunct systemic antibiotic therapy when compared with mechanical debridement alone. Antibiotics tested included metronidazole, clindamycin, tetracycline hydrochloride, amoxicillin, and amoxicillin and potassium clavulanate. Five studies presented a high risk of bias, and 1 study presented an unclear risk. The overall quality of the evidence does not allow the conclusion that adjunct systemic antibiotics are of additional benefit to conventional mechanical debridement alone.

Safety is a critically important factor in the selection of products used in neonatal and paediatric wound care. Given the lack of standardisation of neonatal and paediatric wound care protocols, the goal of this study was to present data on the safety and efficacy of active Leptospermum honey (ALH) in this patient population. A multicentre, retrospective chart review was conducted at eight inpatient facilities and one outpatient clinic between October 2011 and March 2014. The number of applications of ALH, adverse events, and the success of debridement and wound healing were recorded. Data were collected on 115 neonatal and paediatric patients, with 121 wounds requiring debridement, treated with ALH. Patients were treated for an average of 18.7 days. ALH was well tolerated, with two (1.7%) patients reporting adverse events involving a transient stinging sensation on application, which did not prohibit additional applications of ALH. Successful debridement was achieved in 86.0% (104 wounds), and 77.7% (94 wounds) were successfully closed using nonsurgical intervention. Outcomes in neonates were similar to the overall paediatric population, with 86.1% (31/36) wounds successfully debrided with no adverse events. In a subset of six patients with available pre- and post-treatment data, no clinically meaningful changes in white blood cell counts or glucose levels were associated with the initiation of treatment with ALH. The results of this study support ALH as a safe and effective treatment option in this group of patients. This study was supported by a grant from Derma Sciences (Princeton, NJ USA).

2016-01-01

Fiber shedding is a critical problem in biomedical textile debridement materials, which leads to infection and impairs wound healing. In this work, single fiber pull-out test was proposed as an in vitro evaluation for the fiber shedding property of a textile pile debridement material. Samples with different structural design (pile densities, numbers of ground yarns and coating times) were prepared and estimated under this testing method. Results show that single fiber pull-out test offers an appropriate in vitro evaluation for the fiber shedding property of textile pile debridement materials. Pull-out force for samples without back-coating exhibited a slight escalating trend with the supplement in pile density and number of ground yarn plies, while back-coating process significantly raised the single fiber pull-out force. For fiber shedding mechanism analysis, typical pull-out behavior and failure modes of the single fiber pull-out test were analyzed in detail. Three failure modes were found in this study, i.e., fiber slippage, coating point rupture and fiber breakage. In summary, to obtain samples with desirable fiber shedding property, fabric structural design, preparation process and raw materials selection should be taken into full consideration. PMID:28773428

When conservative therapy fails for chronic plantar fasciitis, surgical intervention may be an option. Surgical techniques that maintain the integrity of the plantar fascia will have less risk of destabilizing the foot and will retain foot function. Endoscopic debridement of the plantar fascia can be performed reproducibly to reduce pain and maintain function of the foot. Copyright © 2016 Elsevier Inc. All rights reserved.

Background Immunohistochemical staining experiments have shown that both hemangiogenesis and lymphangiogenesis occur following severe corneal and conjunctival injury and that the neovascularization of the cornea often has severe visual consequences. To better understand how hemangiogenesis and lymphangiogenesis are induced by different degrees of ocular injury, we investigated patterns of injury-induced corneal neovascularization in live Prox1-GFP/Flk1::myr-mCherry mice, in which blood and lymphatic vessels can be imaged simultaneously in vivo. Methods The eyes of Prox1-GFP/Flk1::myr-mCherry mice were injured according to four models based on epithelial debridement of the: A) central cornea (a 1.5-mm-diameter circle of tissue over the corneal apex), B) total cornea, C) bulbar conjunctiva, and D) cornea+bulbar conjunctiva. Corneal blood and lymphatic vessels were imaged on days 0, 3, 7, and 10 post-injury, and the percentages of the cornea containing blood and lymphatic vessels were calculated. Results Neither central corneal nor bulbar conjunctival debridement resulted in significant vessel growth in the mouse cornea, whereas total corneal and corneal+bulbar conjunctival debridement did. On day 10 in the central cornea, total cornea, bulbar conjunctiva, and corneal+bulbar conjunctival epithelial debridement models, the percentage of the corneal surface that was occupied by blood vessels (hemangiogenesis) was 1.9±0.8%, 7.14±2.4%, 2.29±1%, and 15.05±2.14%, respectively, and the percentage of the corneal surface that was occupied by lymphatic vessels (lymphangiogenesis) was 2.45±1.51%, 4.85±0.95%, 2.95±1.27%, and 4.15±3.85%, respectively. Conclusions Substantial corneal debridement was required to induce corneal neovascularization in the mouse cornea, and the corneal epithelium may therefore be partially responsible for maintaining corneal avascularity. General significance Our study demonstrates that GFP/Flk1::myr-mCherry mice are a useful model for studying coordinated hemangiogenic and lymphangiogenic responses. PMID:27233452

Open-to-Air Is a Viable Option for Initial Wound Care in Necrotizing Soft Tissue Infection that Allows Early Detection of Recurrence without Need for Painful Dressing Changes or Return to Operating Room.

The standard treatment of necrotizing soft tissue infection (NSTI) includes extensive surgical debridement. Care of these debridements is challenging because of the size of the wound and associated pain. A potential solution is to leave the wounds open-to-air in the period after the initial debridement, allowing for regular inspection at bedside while reducing pain associated with frequent dressing changes. We evaluated the feasibility of this approach from a pain control standpoint. An audit of wound care modalities used on adult patients with NSTI admitted to a regional burn center between January 2009 and May 2014 was performed. Patients with at least one operation were included. Those opting for palliative care were excluded. Wound care was divided into four categories: open-to-air (OTA), negative-pressure wound therapy (NPWT), packing, and ointment. Wound care, pain score, pain medication use, and number of operations were collected for the first seven days after initial debridement. Pain management was assessed by pain scores. Analgesic use was measured and compared using conversion to morphine milligram equivalents (MME). Ninety-six patients were included; 67% were men with average age of 50 years, resulting in a total of 672 days of wound care evaluated: 69 days of OTA, 127 days of NPWT, 200 days of packing, and 126 days of ointment (150 days were undocumented). Average daily pain score from all wound care modalities was 2.00. Negative pressure wound therapy had the highest reported daily pain score (2.18, p = 0.034), whereas OTA had the lowest pain score (1.63, p < 0.05). Mortality was lower in the OTA cohort but was not statistically significant; there were no other differences in long-term outcome. Leaving wounds OTA is a safe and viable option in the immediate post-debridement period of NSTI to reduce pain, while permitting frequent re-evaluation for quick recognition of disease progression and repeat operative debridement if necessary.

A suture line placed with the same direction as the relaxed skin tension line leads to good healing, but a suture line with over 30 degrees of angle from the relaxed skin tension line leads to longer healing time and more prominent scarring. W-plasty is widely used to change the direction of the scar or to divide it into several split scars. In this study, we applied W-plasty to patients with facial lacerations in the emergency department. From June 2012 to December 2014, 35 patients underwent simple repair or W-plasty for facial lacerations. Patients in the simple repair group underwent resection following a thermal margin, and the W-plasty group was resected within a pre-designed margin of W-shaped laceration. We assessed prognosis using the Stony Brook Scar Evaluation Scale (SBSES) after 10 days (short-term) and six months (long-term), respectively, following suture removal. Among 35 patients, 15 (42.9%) underwent simple debridement and 20 (57.1%) underwent W-plasty. In the W-plasty group, there was no difference between short-term and long-term follow-up showing high SBSES, but in the simple debridement group, long-term follow-up SBSES significantly decreased. W-plasty SBSES was higher than simple debridement at short-term as well as long-term follow-up. We experienced good results of direct W-plasty application at six-month long-term follow-up. Therefore, W-plasty application is more effective in reducing scar appearance than a simple debridement method for facial laceration patients with an angle of 30 degrees or more to the relaxed skin tension line.

Patients treated for early prosthetic joint infection (PJI) with surgical debridement, prosthesis retention and biofilm-active antibiotics, such as rifampicin or fluoroquinolones have a rate of successful infection eradication that is similar to patients treated with the traditional approach of prosthesis exchange. It is therefore important to consider other outcomes after PJI treatment that may influence management decisions, such as function, quality of life (QOL) and treatment-associated complications. To describe rates of successful treatment for patients with PJI undergoing surgical debridement, prosthesis retention and biofilm-active antibiotics and compare their functional outcomes, QOL and complication rates to patients without PJI. Nineteen patients treated for PJI after hip arthroplasty with debridement, prosthesis retention and biofilm-active antibiotics were matched to 76 controls who underwent hip arthroplasty with no infection. Cumulative survival free from treatment failure at 2 years was 88% (95% confidence interval, 59-97%). PJI cases had significant improvement from pre-arthroplasty to 12-months post-arthroplasty in function according to Harris Hip Score and QOL according to the 12-item Short Form Health Survey Physical Component Summary. There was no significant difference in the improvement between controls and cases. PJI was not a risk factor for poor function or QOL. Medical complications occurred more frequently in cases (6/19 (32%)) than controls (9/76 (12%); P = 0.04), with this difference being accounted for by drug reactions. Surgical complications were the same in the two groups. Treatment of PJI with debridement, prosthesis retention and biofilm-active antibiotics is successful, well tolerated and results in significant improvements in function and QOL, which are similar to patients without PJI. © 2013 The Authors; Internal Medicine Journal © 2013 Royal Australasian College of Physicians.

As many doctors know little about gas-forming synergistic necrotizing cellulitis, we retrospectively explored it in our study. Totally, 30 patients diagnosed with gas-forming synergistic necrotizing cellulitis between November 2006 and September 2015 were included. They were divided into two groups: open drainage group (19 patients) and aggressive debridement group (11 patients). Retrospectively analyzed data comprised demographic characteristics, APACHE II scores, pathogen culture results, bleeding amount during the operation, white blood cell count, length of hospital stay and recovery. The mortality rate was 26% in the open drainage group and 73% in the aggressive debridement group (p=0.023). There was no statistical difference in the APACHE II score before treatment between the open drainageand aggressive debridement groups (16.6±4.5 vs 18.1±7.5, p=0.511). The APACHE II score was significantly higher after treatment in the aggressive debridement group (14.2±5.8 score vs 20.1±9.1, p=0.038). There were no statistical differences in the white blood count cell before and after treatment (13.49 × 109±5.05×109 cells/L vs 17.46×109±6.94×109 cells/L, p=0.082; 10.37×109±3.54×109 cells/L vs 15.47×109 ±7.51×109 cells/L, p=0.055; respectively). The bleeding amount during the operation was significantly more in the aggressive debridement group (315±112 ml vs 105±45 ml, p<0.001. For treating gas-forming synergistic necrotizing cellulitis, performing open drainage as early as possible isthe most important procedure after admission.

Utilizing the GentleWave® System for Debridement of Undetected Apical Anatomy.

Debriding and disinfecting complex anatomies within the root canal system pose a major challenge during root canal therapy. Even with current chemomechanical techniques, debris and bacterial remnants are commonly left behind, which are generally believed to increase the risk of endodontic failure. This case details the use of a new technique to debride complex apical anatomy in a maxillary molar. A 48-year-old female presented to the clinic with a chief complaint of increasing pain in her tooth. Clinical examination of the right first maxillary molar (#3) revealed moderate sensitivity to percussion and mild sensitivity to palpation. A pulpal diagnosis of symptomatic irreversible pulpitis and a periapi-cal diagnosis of symptomatic apical periodontitis were made. Mechanical instrumentation was performed using rotary file size #25/.04 for the mesiobuccal and distobuccal canals and size #25/.06 for the palatal canal to create a fluid path and enable obturation of the root canal system following the GentleWave® Procedure. The GentleWave Procedure was completed using Multisonic Ultracleaning™ for complete debridement and disinfection of the root canal system. The tooth was obturated using a warm vertical continuous wave obturation technique. Postoperative radiographs revealed complex anatomy within the apical third that was undetected both during pre-operative radiography and mechanical instrumentation. The palatal canal exhibited a complex apical delta with multiple points of exit, and the mesiobuccal canal revealed an undetected lateral canal within the apical third that had a separate and distinct egress. Conclusion and clinical significance: It is important for the clinician to debride and disinfect complex anatomy within the root canal system to reduce the risk of endodontic failure. This case report highlights the clinical significance of utilizing the GentleWave Procedure for detecting complex apical anatomy during endodontic therapy.

The mortality of patients with bacteremic osteoarticular infections (B-OAIs) is poorly understood. Whether certain types of OAIs carry higher mortality or interventions like surgical debridement can improve prognosis, are unclarified questions. Retrospective analysis of a prospective cohort of patients with B-OAIs treated at a teaching hospital in Barcelona (1985-2014), analyzing mortality (30-day case-fatality rate). B-OAIs were categorized as peripheral septic arthritis or other OAIs. Factors influencing mortality were analyzed using logistic regression models. The association of surgical debridement with mortality in patients with peripheral septic arthritis was evaluated with a multivariate logistic regression model and a propensity score matching analysis. Among 650 cases of B-OAIs, mortality was 12.2% (41.8% of deaths within 7 days). Compared with other B-OAI, cases of peripheral septic arthritis were associated with higher mortality (18.6% vs 8.3%, p < 0.001). In a multiple logistic regression model, peripheral septic arthritis was an independent predictor of mortality (adjusted odds ratio [OR] 2.12; 95% CI: 1.22-3.69; p = 0.008). Cases with peripheral septic arthritis managed with surgical debridement had lower mortality than those managed without surgery (14.7% vs 33.3%; p = 0.003). Surgical debridement was associated with reduced mortality after adjusting for covariates (adjusted OR 0.23; 95% CI: 0.09-0.57; p = 0.002) and in the propensity score matching analysis (OR 0.81; 95% CI: 0.68-0.96; p = 0.014). Among patients with B-OAIs, mortality was greater in those with peripheral septic arthritis. Surgical debridement was associated with decreased mortality in cases of peripheral septic arthritis.

Chronic wounds, including diabetic foot ulcers (DFU), pressure ulcers (PU), and venous ulcers (VU) result from multiple physiologic impairments. Operative debridement is a mainstay of treatment to remove nonviable tissue and to stimulate wound healing. Unlike tumor resection, however, operative wound specimens are not routinely sent for pathology. The objective of this study was to describe the pathology present in chronic wounds. Pathology reports of the skin edge and wound base from 397 initial debridements in 336 consecutive patients with chronic wounds were retrospectively reviewed. All data were entered and stored in a Wound Electronic Medical Record. Pathology data were extracted from the Wound Electronic Medical Record, coded, and quantified. Up to 15 distinct histopathologic findings across 7 tissue types were observed after review of pathology reports from chronic wounds. Specifically, the pathology of epidermis revealed hyperkeratosis: 66% in DFUs, 31% in PUs, and 29% in VUs. Dermal pathology revealed fibrosis in 49% of DFUs, 30% of PUs, and 15% of VUs. Wound bed pathology revealed necrosis in the subcutaneous tissue in 67% of DFUs, 55% of PUs, and 19% of VUs. Fibrosis was reported in between 19% and 52% of all wound types. Acute osteomyelitis was present in 39% of DFUs, 33% of PUs, and 29% of VUs. This observational study of the histopathology of initial surgical debridement of chronic wounds revealed a wide range of findings across multiple tissue levels. Although certain findings such as osteomyelitis and gangrene have been shown to directly relate to impaired wound healing and amputation, other findings require additional investigation. To rigorously define a margin of debridement, a prospective study relating histopathology and clinical outcomes such as healing rates and amputation is needed.

Background This study compared the results of patients treated for ulnar impaction syndrome using an ulnar shortening osteotomy (USO) alone with those treated with combined arthroscopic debridement and USO. Methods The results of 27 wrists were reviewed retrospectively. They were divided into three groups: group A (USO alone, 10 cases), group B (combined arthroscopic debridement and USO, 9 cases), and group C (arthroscopic triangular fibrocartilage complex [TFCC] debridement alone, 8 cases). The wrist function was evaluated using the modified Mayo wrist score, disabilities of the arm, shoulder and hand (DASH) score and Chun and Palmer grading system. Results The modified Mayo wrist score in groups A, B, and C was 74.5 ± 8.9, 73.9 ± 11.6, and 61.3 ± 10.2, respectively (p < 0.05). The DASH score in groups A, B, and C was 15.6 ± 11.8, 19.3 ± 11.9, and 33.2 ± 8.5, respectively (p < 0.05). The average Chun and Palmer grading score in groups A and B was 85.7 ± 8.9 and 84.7 ± 6.7, respectively. The difference in the Mayo wrist score, DASH score and Chun and Palmer grading score between group A and B was not significant (p > 0.05). Conclusions Both USO alone and combined arthroscopic TFCC debridement with USO improved the wrist function and reduced the level of pain in the patients treated for ulnar impaction syndrome. USO alone may be the preferred method of treatment in patients if the torn flap of TFCC is not unstable. PMID:21909465

Sacroiliac joint tuberculosis(SJT) is relatively uncommon, but it may cause severe sacroiliac joint destruction and functional disorder. Few studies in the literature have been presented on SJT, reports of surgical treatment for SJT are even fewer. In this study, we retrospectively reviewed surgical management of patients with severe SJT of 3 different types and proposed to reveal the clinical manifestations and features and aim to determine the efficiency and security of such surgical treatment. We reviewed 17 patients with severe SJT of 3 different types who underwent posterior open-window focal debridement and bone graft for joint fusion. Among them,five patients with anterior sacral abscess had anterior abscess curettage before debridement. Two patients with lumbar vertebral tuberculosis received one-stage posterior tuberculous debridement, interbody fusion and instrumentation. Follow-up was performed 36 months (26 to 45 months) using the following parameters: erythrocyte sedimentation rate(ESR), status of joint bony fusion on CT scan, visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Buttock pain and low back pain were progressively relieved with time. 6 months later, pain was not obvious, and ESR resumed to normal levels within 3 months. Solid fusion of the sacroiliac joint occurred within 12 months in all cases. No complications or recurrence occurred. At final follow-up, all patients had no pain or only minimal discomfort over the affected joint and almost complete functional recovery. Posterior open-window focal debridement and joint fusion is an efficient and secure surgical method to treat severe SJT. If there is an abscess in the front of the sacroiliac joint, anterior abscess curettage should be performed as a supplement.

Debridement is an essential act in the treatment of various wounds, which removes devitalized and colonized necrotic tissue, also poorly healing tissue and all foreign bodies from the wound, in order to enhance the formation of healthy granulation tissue and accelerate the process of wound healing. Nowadays, debridement is the basic procedure in the management of acute and chronic wounds, where the question remains which way to do it, how extensively, how often and who should perform it. Many parameters affect the decision on what method to use on debridement. It is important to consider the patient's age, environment, choice, presence of pain, quality of life, skills and resources for wound and patient care providers, and also a variety of regulations and guidelines. Irrespective of the level and setting where the care is provided (hospital patients, ambulatory or stationary, home care), care for patients suffering from some form of acute or chronic wound and requiring different interventions and a large number of frequent bandaging and wound care is most frequently provided by nurses/technicians. With timely and systematic interventions in these patients, the current and potential problems in health functioning could be minimized or eliminated in accordance with the resources. Along with daily wound toilette and bandaging, it is important to timely recognize changes in the wound status and the need of tissue debridement. Nurse/technician interventions are focused on preparation of the patient (physical, psychological, education), preparation of materials, personnel and space, assisting or performing procedures of wound care, and documenting the procedures performed. The assumption that having an experienced and competent person for wound care and a variety of methods and approaches in wound treatment is in the patient's best interest poses the need of defining common terms and developing comprehensive guidelines that will lead to universal algorithms in the field.

Low-Frequency Ultrasound Debridement in Chronic Wound Healing: A Systematic Review of Current Evidence

PubMed Central

Chang, Ying-Ju Ruby; Perry, Julie

2017-01-01

Chronic wounds are painful and debilitating to patients, pose a clinical challenge to physicians, and impose financial burden on the health-care system. New treatment options are therefore highly sought after. Ultrasound debridement is a promising technology that functions to disperse bacterial biofilms and stimulate wound healing. In this review, we focus on low-frequency ultrasound (20-60 kHz) and summarize the findings of 25 recent studies examining ultrasound efficacy. Ultrasound debridement appears to be most effective when used 3 times a week and has the potential to decrease exudate and slough, decrease patient pain, disperse biofilms, and increase healing in wounds of various etiology. Although current studies are generally of smaller size, the results are promising and we recommend the testing of low-frequency ultrasound therapy in clinical practice on a larger scale.

Debridement versus re-attachment of acetabular labral tears: A review of the literature and quantitative analysis.

PubMed

Haddad, B; Konan, S; Haddad, F S

2014-01-01

We have reviewed the current literature to compare the results of surgery aimed to repair or debride a damaged acetabular labrum. We identified 28 studies to be included in the review containing a total of 1631 hips in 1609 patients. Of these studies 12 reported a mean rate of good results of 82% (from 67% to 100%) for labral debridement. Of the 16 studies that reported a combination of debridement and re-attachment, five reported a comparative outcome for the two methods, four reported better results with re-attachment and one study did not find any significant difference in outcomes. Due to the heterogeneity of the studies it was not possible to perform a meta-analysis or draw accurate conclusions. Confounding factors in the studies include selection bias, use of historical controls and high rates of loss of follow-up. It seems logical to repair an unstable tear in a good quality labrum with good potential to heal in order potentially to preserve its physiological function. A degenerative labrum on the other hand may be the source of discomfort and its preservation may result in persistent pain and the added risk of failure of re-attachment. The results of the present study do not support routine refixation for all labral tears.

Microfracture of cartilage defects may induce alterations of the subchondral bone in the mid- and long-term, yet very little is known about their onset. Possibly, these changes may be avoided by an enhanced microfracture technique with additional application of bone marrow aspirate. In this study, full-thickness chondral defects in the knee joints of minipigs were either treated with (1) debridement down to the subchondral bone plate alone, (2) debridement with microfracture, or (3) microfracture with additional application of bone marrow aspirate. At 4 weeks after microfracture, the loss of subchondral bone below the defects largely exceeded the original microfracture holes. Of note, a significant increase of osteoclast density was identified in defects treated with microfracture alone compared with debridement only. Both changes were significantly counteracted by the adjunct treatment with bone marrow. Debridement and microfracture without or with bone marrow were equivalent regarding the early cartilage repair. These data suggest that microfracture induced a substantial early resorption of the subchondral bone and also highlight the potential value of bone marrow aspirate as an adjunct to counteract these alterations. Clinical studies are warranted to further elucidate early events of osteochondral repair and the effect of enhanced microfracture techniques. PMID:28345610

Purpose. The mouse has become an important wound healing model with which to study corneal fibrosis, a frequent complication of refractive surgery. The aim of the current study was to quantify changes in stromal ultrastructure and light scatter that characterize fibrosis in mouse corneal debridement wounds. Methods. Epithelial debridement wounds, with and without removal of basement membrane, were produced in C57BL/6 mice. Corneal opacity was measured using optical coherence tomography, and collagen diameter and matrix order were quantified by x-ray scattering. Electron microscopy was used to visualize proteoglycans. Quantitative PCR (Q-PCR) measured mRNA transcript levels for several quiescent and fibrotic markers. Results. Epithelial debridement without basement membrane disruption produced a significant increase in matrix disorder at 8 weeks, but minimal corneal opacity. In contrast, basement membrane penetration led to increases in light scatter, matrix disorder, and collagen diameter, accompanied by the appearance of abnormally large proteoglycans in the subepithelial stroma. This group also demonstrated upregulation of several quiescent and fibrotic markers 2 to 4 weeks after wounding. Conclusions. Fibrotic corneal wound healing in mice involves extensive changes to collagen and proteoglycan ultrastructure, consistent with deposition of opaque scar tissue. Epithelial basement membrane penetration is a deciding factor determining the degree of ultrastructural changes and resulting opacity. PMID:22467580

Most cases of sacral osteomyelitis arising in the setting of sacral pressure ulcers require minimal cortical debridement. When faced with advanced bony involvement, the surgeon is often unclear about how much can safely be resected. Unfamiliarity with sacral anatomy can lead to concerns of inadvertent entry into the dural space and compromise of future flap options. A cadaveric study (n = 6), in which a wide posterior dissection of the sacrum, was performed. Relationships of the dural sac to bony landmarks of the posterior pelvis were noted. The termination of the dural sac was found in our study to occur at the junction of S2/S3 vertebral bodies, which was located at a mean distance of 0.38 ± 0.16 cm distal to the inferior-most extent of the posterior superior iliac spine (PSIS). The mean thickness of the posterior table of sacrum at this level was 1.7 cm at the midline and 0.5 cm at the sacral foramina. The PSIS is a reliable landmark for localizing the S2/S3 junction and the termination of the dural sac. Sacral debridement medial to the sacral foramina above the level of PSIS must be conservative whenever possible. If aggressive debridement is necessary above this level, the surgeon must be alert to the possibility of dural involvement.

Hyper-hydration: a new perspective on wound cleansing, debridement and healing.

PubMed

2016-06-01

In a recent symposium organised by Hartmann, the involvement of moisture and hydration in healing was re-evaluated and the use of hyper-hydration in promoting healing was examined. The distinction between hyperhydration and maceration was also discussed. Clinical studies were presented to give an overview of the clinical evidence to how Hydro-Responsive Wound Dressings can aid in healing via cleansing, debridement and desloughing of several wound types.

Wound bed preparation: A novel approach using HydroTherapy.

PubMed

Atkin, Leanne; Ousey, Karen

2016-12-01

Wounds that fail to heal quickly are often encountered by community nursing staff. An important step in assisting these chronic or stalled wounds progress through healing is debridement to remove devitalised tissue, including slough and eschar, that can prevent the wound from healing. A unique wound treatment called HydroTherapy aims to provide an optimal healing environment. The first step of HydroTherapy involves HydroClean plus™, this dressing enables removal of devitalised tissue through autolytic debridement and absorption of wound fluid. Irrigation and cleansing provided by Ringer's solution from the dressing further removes any necrotic tissue or eschar. Once effective wound bed preparation has been achieved a second dressing, HydroTac™, provides an ongoing hydrated wound environment that enables re-epithelialisation to occur in an unrestricted fashion. This paper presents 3 case studies of slow healing wounds treated with HydroClean plus™ which demonstrates effective wound debridement.

Mastectomy skin necrosis is a significant problem after breast reconstruction. This complication may lead to poor wound healing and need for implant removal, which may delay subsequent oncologic treatment. We sought to characterize factors associated with mastectomy skin necrosis and propose a management algorithm. A retrospective review was performed on consecutive patients undergoing implant-based breast reconstruction by the senior author from 2006 through 2015. Patient-level factors including age, race, body mass index, history of hypertension, history of diabetes, history of smoking, and history of radiation were collected. Surgical factors including type of mastectomy, location of implant placement, and immediate versus delayed reconstruction were collected. The incidence and treatment of mastectomy skin necrosis were analyzed. A total of 293 patients underwent either unilateral or bilateral implant-based breast reconstructions after mastectomy with a total of 471 reconstructed breasts. Mastectomy skin necrosis was observed in 8.1% of reconstructed breasts. Skin necrosis was not associated with age, hypertension, diabetes, prior radiation, or type of mastectomy. The incidence of skin necrosis was higher among smokers (17.9% vs 5.0%, P < 0.001), among patients with higher body mass index (11.4% vs 6.1%, P = 0.05), patients who underwent immediate reconstruction compared to delayed (9.6% vs 0%, P = 0.004), placement of expander under acellular dermal matrix compared with submuscular placement (12.0% vs 5.2%, P = 0.02), and use of higher initial expander fill volume compared with lower fill volume (11.4% vs 5.4%, P = 0.02).The median necrosis size was 8 cm. The median time to treatment was 15 days postoperatively. In 55% of patients minor necrosis was treated with clinic debridement, whereas 43% had larger areas of necrosis requiring operative debridement. The median size treated with clinic debridement was 5.5 cm, compared to 15 cm for operative debridement. All necrosis was treated in a timely fashion and did not delay adjuvant therapy. Mastectomy skin necrosis occurred in 8.1% of breasts after implant-based reconstruction. Necrosis less than 10 cm can be treated successfully with local debridement in the clinic setting. Timely and appropriate treatment of skin necrosis with debridement and primary closure expedites wound healing and facilitates tissue expander breast reconstruction.

The treatment of concomitant cartilage lesions in anterior cruciate ligament (ACL)-injured knees is debatable. To evaluate the effect of debridement or microfracture (MF) compared with no treatment of concomitant full-thickness (International Cartilage Repair Society [ICRS] grades 3-4) cartilage lesions on patient-reported outcomes after ACL reconstruction. Cohort study; Level of evidence, 2. Six hundred forty-four patients who underwent primary unilateral ACL reconstruction and had a concomitant full-thickness cartilage lesion treated simultaneously by debridement (n = 129) or MF (n = 164), or underwent no treatment (n = 351) of the cartilage lesion, registered in the Norwegian and Swedish National Knee Ligament Registries from 2005 to 2008 were included. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was used to measure patient-reported outcomes. At a mean follow-up of 2.1 ± 0.2 years after surgery, 357 (55%) patients completed the KOOS. Linear regression analyses were used to evaluate the effect of debridement or MF on the KOOS. No significant effects of debridement were detected in the unadjusted or adjusted regression analyses on any of the KOOS subscales at 2-year follow-up. The MF treatment of the cartilage lesions had significant negative effects at 2-year follow-up on the KOOS Sport and Recreation (Sport/Rec) (regression coefficient [β] = -8.9; 95% confidence interval [CI], -15.1 to -1.5) and Knee-Related Quality of Life (QoL) (β = -8.1; 95% CI, -14.1 to -2.1) subscales in the unadjusted analyses. When adjusting for confounders, MF had significant negative effects on the same KOOS subscales of Sport/Rec (β = -8.6; 95% CI, -16.4 to -0.7) and QoL (β = -7.2; 95% CI, -13.6 to -0.8). For the remaining KOOS subscales of Pain, Symptoms, and Activities of Daily Living, there were no significant unadjusted or adjusted effects of MF. MF of concomitant full-thickness cartilage lesions showed adverse effects on patient-reported outcomes at 2-year follow-up after ACL reconstruction. Debridement of concomitant full-thickness cartilage lesions showed neither positive nor negative effects on patient-reported outcomes at 2-year follow-up after ACL reconstruction. © 2015 The Author(s).

The neural guidance protein semaphorin 3A (Sema3A) is expressed in corneal epithelial cells of the adult rat. We have now further investigated the localization of Sema3A in the normal rat corneal epithelium as well as changes in its expression pattern during wound healing after central corneal epithelial debridement. The expression pattern of Sema3A was compared with that of the tight-junction protein zonula occludens-1 (ZO-1), the gap-junction protein connexin43 (Cx43), or the cell proliferation marker Ki67. Immunofluorescence analysis revealed that Sema3A was present predominantly in the membrane of basal and wing cells of the intact corneal epithelium. The expression of Sema3Amore » at the basal side of basal cells was increased in the peripheral epithelium compared with that in the central region. Sema3A was detected in all layers at the leading edge of the migrating corneal epithelium at 6 h after central epithelial debridement. The expression of Sema3A was markedly up-regulated in the basal and lateral membranes of columnar basal cells apparent in the thickened, newly healed epithelium at 1 day after debridement, but it had largely returned to the normal pattern at 3 days after debridement. The expression of ZO-1 was restricted to superficial epithelial cells and remained mostly unchanged during the wound healing process. The expression of Cx43 in basal cells was down-regulated at the leading edge of the migrating epithelium but was stable in the remaining portion of the epithelium. Ki67 was not detected in basal cells of the central epithelium at 1 day after epithelial debridement, when Sema3A was prominently expressed. Immunoblot analysis showed that the abundance of Sema3A in the central cornea was increased 1 day after epithelial debridement, whereas that of ZO-1 or Cx43 remained largely unchanged. This increase in Sema3A expression was accompanied by up-regulation of the Sema3A coreceptor neuropilin-1. Our observations have thus shown that the expression of Sema3A is increased markedly in basal cells of the newly healed corneal epithelium, and that this up-regulation of Sema3A is not associated with cell proliferation. They further suggest that Sema3A might play a role in the regulation of corneal epithelial wound healing.« less

Our aim was to assess the effectiveness of hydro-responsive wound dressing (HRWD) in debridement and wound bed preparation of a variety of acute and chronic wounds that presented with devitalised tissue needing removal so that healing may proceed. This was a non-comparative evaluation of acute and chronic wounds that required debridement as part of their normal treatment regimen. Clinicians recorded wound changes including a subjective assessment level of devitalised tissue and wound bed preparation, presence of pain, wound status (e.g., wound size) and periwound skin condition. Data was also collected from clinicians and patients to provide information on clinical performance of the dressing. We recruited 100 patients with a variety of wound types into the study. Over 90% of the clinicians reported removal of devitalised tissue to enable a healing response in both chronic and acute wounds. Specifically, over the course of the evaluation period, levels of devitalised tissue (necrosis and slough) reduced from 85.5% to 26.3%, and this was accompanied by an increase in wound bed granulation from 12.0% to 33.7%. Correspondingly, there was a 40% reduction in wound area, hence a clinically relevant healing response was seen upon treatment with HRWD. It is also noteworthy that this patient population included a significant proportion of chronic wounds (51.4%) that showed no signs of wound progression within <4 weeks before study inclusion. Of these chronic wounds, 93% demonstrated wound progression upon treatment with HRWD. Despite reported pain levels being low pre- and post-dressing change, overall wound pain improved (reduced) in 48% of patients. Periwound skin condition showed a tendency towards improvement, and the fluid management capabilities of the HRWD was reported as good to excellent in the majority of cases. Wound infections were reduced by at least 60% over the evaluation period. A simple cost-effective analysis demonstrated significant savings using HRWD (£6.33) over current standard practice regimens of a four-step debridement process (£8.05), larval therapy (£306.39) and mechanical pad debridement (£11.46). HRWD was well tolerated and was demonstrated to be an efficient debridement tool providing rapid, effective and pain free debridement in a variety of wound types.

The treatment of rotator cuff injury in the absence of a full-thickness tear has traditionally consisted of acromioplasty. However, this disorder may also be treated by arthroscopic rotator cuff debridement without acromioplasty. Our previous study of 79 shoulders so treated reported 87% good or excellent results at an average 53-month follow-up. The purpose of this article is to report the long-term, average 9.5-year follow-up of this cohort. Long-term follow-up of case series. We retrospectively reviewed the records of 62 shoulders in 60 patients who had undergone arthroscopic rotator cuff debridement for partial-thickness rotator cuff tears. Demographic criteria, residual pain, and the ability to return to recreational athletics were noted. The UCLA Shoulder Score and the Simple Shoulder Test scores were determined and statistical analysis performed. Using the UCLA Shoulder Score, there were 79% excellent or good results at an average 114 months of follow-up. Patients with Workers' Compensation claims had significantly worse results, with only 40% rated good or excellent. Of the 60 patients, 77% had no or only minimal pain, 57% were still able to perform recreational athletics without difficulty, and 20% could participate at a lower level of intensity. Arthroscopic debridement of rotator cuff injury in the absence of a full-thickness tear has good long-term results and minimizes additional surgical trauma. Level IV, case series.

Arthroscopic synovectomy, irrigation, and debridement for treatment of septic ankle arthrosis: a systematic review and case series.

Septic arthrosis of the ankle is a rare, often devastating, infection, with a high potential for morbidity and mortality. Delay in treatment can lead to cartilage erosion, painful synovitis, and osteomyelitis. Septic ankle arthrosis deserves prompt recognition and intervention. However, quality, sound, protocol-directed arthroscopic treatment of septic ankle arthrosis of the ankle has not yet been reported. We performed a systematic review of the electronic databases and other relevant peer-reviewed sources to determine the outcomes and treatment protocols associated with septic ankle arthrosis treated with arthroscopic synovectomy, irrigation, and debridement. Nine studies, involving a total of 15 ankles, met our inclusion criteria. In addition, we present the short-term outcomes of a protocol-driven arthroscopic synovial biopsy, deep culture procurement, synovectomy, irrigation, and debridement approach for 8 ankles (8 patients). To our knowledge, this would be the largest individual case series specific to arthroscopic treatment of septic ankle arthrosis. The most common infectious organism reported in the systematic review and in our case series was methicillin-sensitive Staphylococcus aureus. Arthroscopic synovectomy, irrigation, and debridement represents an acceptable treatment method for septic ankle arthrosis and demonstrated outcomes similar to the more traditional open approach, with fewer complications. Additional, appropriately weighted, randomized controlled studies with long-term follow-up are warranted. Copyright © 2014 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

Sulphur mustard (bis-2-chloroethyl sulphide; HD) exposure acutely produces lesions that vary from mild erythema, to blister formation, to necrosis. When blisters occur, with or without necrosis, healing of the lesions is delayed. Weanling pigs exposed to a mild erythema-producing dose of HD and to a moderate erythema-producing dose that consistently gave microblister formation were treated with CO2 laser (Tru-Pulse) debridement at 6, 24 or 48 h after exposure. The histopathological features observed at 14 days after exposure in control skin and skin exposed to both HD doses were compared with the features observed in CO2 laser-debrided skin in non-exposed and HD-exposed skin sites. The overlying epidermis in the non-laser treated lesions was thin, with cytological atypia and squamoid changes within the basal cell layer, as well as scattered apoptotic/necrotic keratinocytes. An increased inflammatory infiltrate and necrobiotic changes in the dermis were seen at the higher HD dose. All laser-treated lesions appeared identical, with a thick, differentiated epidermis and a well-formed basal cell layer. There was minimal inflammatory infiltrate. In the papillary dermis there were increased stromal cells. Laser debridement of mild clinical lesions induced by HD produced a more functional epidermis by 14 days as well as clearing the epidermis of damaged keratinocytes.

Endoscopic transmural drainage/debridement of pancreatic walled-off necrosis (WON) has been performed using double-pigtail plastic (DP), fully covered self-expanding metal stents (FCSEMSs), or the novel lumen-apposing fully covered self-expanding metal stent (LAMS). Our aim was to perform a retrospective cohort study to compare the clinical outcomes and adverse events of EUS-guided drainage/debridement of WON with DP stents, FCSEMSs, and LAMSs. Consecutive patients in 2 centers with WON managed by EUS-guided debridement were divided into 3 groups: (1) those who underwent debridement using DP stents, (2) debridement using FCSEMSs, (3) debridement using LAMSs. Technical success (ability to access and drain a WON by placement of transmural stents), early adverse events, number of procedures performed per patient to achieve WON resolution, and long-term success (complete resolution of the WON without need for further reintervention at 6 months after treatment) were evaluated. From 2010 to 2015, 313 patients (23.3% female; mean age, 53 years) underwent WON debridement, including 106 who were drained using DP stents, 121 using FCSEMSs, and 86 using LAMSs. The 3 groups were matched for age, cause of the pancreatitis, WON size, and location. The cause of the patients' pancreatitis was gallstones (40.6%), alcohol (30.7%), idiopathic (13.1%), and other causes (15.6%). The mean cyst size was 102 mm (range, 20-510 mm). The mean number of endoscopy sessions was 2.5 (range, 1-13). The technical success rate of stent placement was 99%. Early adverse events were noted in 27 of 313 (8.6%) patients (perforation in 6, bleeding in 8, suprainfection in 9, other in 7). Successful endoscopic therapy was noted in 277 of 313 (89.6%) patients. When comparing the 3 groups, there was no difference in the technical success (P = .37). Early adverse events were significantly lower in the FCSEMS group compared with the DP and LAMS groups (1.6%, 7.5%, and 9.3%; P < .01). At 6-month follow-up, the rate of complete resolution of WON was lower with DP stents compared with FCSEMSs and LAMSs (81% vs 95% vs 90%; P = .001). The mean number of procedures required for WON resolution was significantly lower in the LAMS group compared with the FCSEMS and DP groups (2.2 vs 3 vs 3.6, respectively; P = .04). On multivariable analysis, DP stents remain the sole negative predictor for successful resolution of WON (odds ratio [OR], 0.18; 95% confidence interval, 0.06-0.53; P = .002) after adjusting for age, sex, and WON size. Although there was no significant difference between FCSEMSs and LAMSs for WON resolution, the LAMS was more likely to have early adverse events (OR, 6.6; P = .02). EUS-guided drainage/debridement of WON using FCSEMSs and LAMSs is superior to DP stents in terms of overall treatment efficacy. The number of procedures required for WON resolution was significantly lower with LAMSs compared with FCSEMSs and DP stents. Copyright © 2017 American Society for Gastrointestinal Endoscopy.

2016-08-01

Faculty calibration studies for calculus detection use two different standards for examiner evaluation, yet the only therapeutic modality that can be used for nonsurgical periodontal treatment is scaling/root debridement or planing. In this study, a pretest-posttest design was used to assess the feasibility of faculty calibration for calculus detection using two accepted standards: that established by the Central Regional Dental Testing Service, Inc. (CRDTS; readily detectible calculus) and the gold standard for scaling/root debridement (root roughness). Four clinical dental hygiene faculty members out of five possible participants at Halifax Community College agreed to participate. The participants explored calculus on the 16 assigned teeth (64 surfaces) of four patients. Calculus detection scores were calculated before and after training. Kappa averages using CRDTS criteria were 0.561 at pretest and 0.631 at posttest. Kappa scores using the scaling/root debridement or planing standard were 0.152 at pretest and 0.271 at posttest. The scores indicated improvement from moderate (Kappa=0.41-0.60) to substantial agreement (Kappa=0.61-0.80) following training using the CRDTS standard. Although this result differed qualitatively and Kappas were significantly different from 0, the differences for pre- to post-Kappas for patient-rater dyads using CRDTS were not statistically significant (p=0.778). There was no difference (p=0.913) in Kappa scores pre- to post-training using the scaling/root debridement standard. Despite the small number of participants in this study, the results indicated that training to improve interrater reliability to substantial agreement was feasible using the CRDTS standard but not using the gold standard. The difference may have been due to greater difficulty in attaining agreement regarding root roughness. Future studies should include multiple training sessions with patients using the same standard for scaling/root debridement used for evaluation of students.

The care of traumatic wounds has evolved over hundreds of years, largely as a result of armed conflicts. The lessons learned during World War I in the treatment of extensive soft-tissue injuries proved invaluable in reducing infection and preventing loss of limb and life. Foremost among these was the use of debridement. This report reviews the development of debridement as standard treatment of war wounds and highlights the surgeon largely responsible for its resurgence during one of this century's saddest chapters. Before World War I, the care of wounds consisted of minimal exploration and liberal use of then-new antiseptics. For limited injuries, this approach appeared adequate. World War I saw the introduction of devastating weapons that produced injuries that caused extensive devitalization of tissue. Standard treatment of these patients proved woefully inadequate to prevent life-threatening infections. This is a historical review of the conditions that occurred during World War I that prompted a change in wound management. One of those responsible for this change was the Belgian surgeon Antoine Depage. His life and contributions to the care of war wounds are profiled. Depage reintroduced the discarded French practice of wound incision and exploration (debridement) and combined it with excision of devitalized tissue. Through the use of debridement, excision, and delayed wound closure based on bacteriologic survey, Depage was able to reduce the incidence of infectious complications of soft-tissue injuries, particularly those involving fractures. Through his experiences in the Great War, Antoine Depage was able to formulate a treatment plan for wounds of war. All such injuries were assumed to be contaminated and, as such, they required early and careful debridement. Depage thought that wound closure should often be delayed and based his decision to close on the bacteriologic status of the wound. To him, we owe our current management of traumatic wounds.

The purpose of this investigation was to determine whether arthroscopic debridement of primary elbow osteoarthritis results in statistically significant and clinically relevant improvement in (1) elbow range of motion and (2) clinical outcomes with (3) low complication and reoperation rates. A systematic review was registered with PROSPERO and performed using PRISMA guidelines. Databases were searched for studies that investigated the outcomes of arthroscopic debridement for the treatment of primary osteoarthritis of the elbow in adult human patients. Study methodological quality was analyzed. Studies that included post-traumatic arthritis were excluded. Elbow motion and all elbow-specific patient-reported outcome scores were eligible for analysis. Comparisons between preoperative and postoperative values from each study were made using 2-sample Z-tests (http://in-silico.net/tools/statistics/ztest) using a P value < .05. Nine articles (209 subjects, 213 elbows, 187 males, 22 females, mean age 45.7 ± 7.1 years, mean follow-up 41.7 ± 16.3. months; 75% right, 25% left; 79% dominant elbow, 21% nondominant) were analyzed. Elbow extension (23.4°-10.7°, Δ 12.7°), flexion (115.9°-128.7°, Δ 12.8°), and global arc of motion (94.5°-117.6°, Δ 23.1°) had statistically significant and clinically relevant improvement following arthroscopic debridement (P < .0001 for all). There was also a statistically significant (P < .0001) and clinically relevant improvement in the Mayo Elbow Performance Score (60.7-84.6, Δ 23.9) postoperatively. Six patients (2.8%) had postoperative complications. Nine (4.2%) underwent reoperation.

The lessons learned during World War I in the treatment of extensive soft-tissue injuries proved invaluable in reducing infection and preventing loss of limb and life. Foremost among these was the use of debridement. This report reviews the development of debridement as standard treatment of war wounds and highlights the surgeon largely responsible for its resurgence during one of this century's saddest chapters. SUMMARY BACKGROUND DATA: Before World War I, the care of wounds consisted of minimal exploration and liberal use of then-new antiseptics. For limited injuries, this approach appeared adequate. World War I saw the introduction of devastating weapons that produced injuries that caused extensive devitalization of tissue. Standard treatment of these patients proved woefully inadequate to prevent life-threatening infections. METHODS: This is a historical review of the conditions that occurred during World War I that prompted a change in wound management. One of those responsible for this change was the Belgian surgeon Antoine Depage. His life and contributions to the care of war wounds are profiled. Depage reintroduced the discarded French practice of wound incision and exploration (debridement) and combined it with excision of devitalized tissue. RESULTS: Through the use of debridement, excision, and delayed wound closure based on bacteriologic survey, Depage was able to reduce the incidence of infectious complications of soft-tissue injuries, particularly those involving fractures. CONCLUSIONS: Through his experiences in the Great War, Antoine Depage was able to formulate a treatment plan for wounds of war. All such injuries were assumed to be contaminated and, as such, they required early and careful debridement. Depage thought that wound closure should often be delayed and based his decision to close on the bacteriologic status of the wound. To him, we owe our current management of traumatic wounds.

The purpose of this study is to compare the clinical outcomes of surgical management by one-stage posterior debridement, transforaminal lumbar interbody fusion (TLIF) and instrumentation and combined posterior and anterior approaches for lumbar spinal tuberculosis, and determine the clinical effectiveness of the posterior only surgical treatment for lumbar spinal TB at the same time. Thirty-seven patients who suffered lumbar tuberculosis were treated by two different surgical procedures in our center from May 2004 to June 2012. All the cases were divided into two groups: 19 cases in Group A underwent one-stage posterior debridement, TLIF and instrumentation, and 18 cases in Group B underwent posterior instrumentation, anterior debridement and bone graft in a single-stage procedure. The operation time, blood loss, lumbar kyphotic angle, recovery of neurological function and fusion time were, respectively, compared between Group A and Group B. The average follow-up period for Group A was 46.6 ± 16.7 months, and for Group B, 47.5 ± 15.0 months. It was obvious that the average operative duration and blood loss of Group A was less than those of Group B. Lumbar tuberculosis was completely cured and the grafted bones were fused in 10 months in all patients. There was no persistence or recurrence of infection and no differences in the radiological results in both groups. The kyphosis was significantly corrected after surgical management. The average pretreatment ESR was 60.7 ± 22.5 mm/h, which became normal (9.0 ± 2.8 mm/h) within 3 months in all patients. Surgical management by one-stage posterior debridement, TLIF and instrumentation for lumbar tuberculosis is feasible and effective. This approach obtained better clinical outcomes than combined posterior and anterior surgeries.

Endoscopic treatment of Morel-Lavallee lesion.

Morel-Lavallee lesion is a closed degloving soft tissue injury in which subcutaneous tissue is torn from the underlying muscular fascia. The tear leads to venolymphatic leak, and concomitant adipose tissue necrosis from the force of the trauma causes swelling and possible infection at the site of injury. The traditional treatment for the lesion is surgical drainage and debridement. In this report, an endoscopic method is described, which achieves the goal of an open surgical debridement but minimizes surgical morbidity. Copyright © 2016 Elsevier Ltd. All rights reserved.

Three cases of Aspergillus fumigatas vertebral osteomyelitis failed courses of medical treatment. Each was subsequently treated with anterior vertebral debridement and posterior segmental spinal instrumentation. Despite poor nutritional and immune systems, resolution of the infection and subsequent anterior ankylosis occurred in each patient, with follow-up ranging from 1 to 3 years. If patients with aspergillus vertebral osteomyelitis do not respond to medical treatment, early surgical debridement and stabilization in combination with intravenous amphotericin B can lead to resolution and bony ankylosis.

Cervical necrotizing fasciitis secondary to epiglottitis is rare. The standard treatment of this severe condition has long been early and aggressive surgical debridement and adequate antimicrobial therapy. We report the case of an immunocompetent 59-year-old man who developed cervical necrotizing fasciitis as a complication of acute epiglottitis. We were able to successfully manage this patient with conservative surgical treatment (incision and drainage, in addition to antibiotic therapy) that did not involve aggressive debridement.

Debridement, antibiotic, and implant retention (DAIR) is an attractive treatment modality after hip hemiarthroplasty (HA) infections. Data about the success of the procedure after acute onset infections is lacking. The aim of this study was to analyze the clinical outcome and associated risk factors. A multicenter, retrospective cohort study was designed, including 39 patients with acute onset prosthetic infection who had undergone debridement and irrigation with prosthesis retention. The primary outcome measure was infection eradication without prosthesis removal. We also analyzed how the success rate was influenced by the length of the interval between implantation of the prosthesis and the beginning of the treatment. The overall success rate was 41%. Sedimentation rate over 60 mm/h and the longer duration (2 weeks) after prosthesis implantation were found as factors negatively influencing the success rate. Our results indicated limited success to DAIR- treated patients with infected HA. The high failure rate of DAIR treatment after 2 weeks from the implantation should be taken into consideration.

Fungal osteomyelitis is an uncommon diseases and generally present in an indolent fashion. Isolated bone affection due to fungi are rare and we present one such case with fungal osteomyelitis of terminal phalanx of second toe. We present a rare case of fungal osteomyelitis of right second toe in a 30 year old Indian female who presented with swelling of 8 months duration. Diagnosis was based on the histo-pathological report and culture showing Aspergillus growth. The patient was treated with surgical debridement and amphotericin-B was given for 6 weeks after debridement. There was no recurrence one year post surgery. Isolated Aspergillus osteomyelitis of the bone are very rare and mostly seen in immunocompromised patients and larger bones like spine, femur and tibia. Treatment with wound debridement and subsequently followed up with a course of Amphotericin-B for 6 weeks provided good results. There was no recurrence noted at 1 year follow up. Fungi should be kept in mind for differential diagnosis of osteomyelitis and culture should be appropriately ordered.

A microbe free root canal space before obturation leads to higher success rate and conventional chemo-mechanical debridement might not achieve this goal completely. First trials of laser in dentistry started from surgical intervention on caries and bones of oral cavity and extended to prepare cavities and even shaping root canals. Afterward lasers were implicated soon into direct debridement of root canal space. Anyhow failure of laser to remove debris totally from root canal space is demonstrated recently, additionally it might lead to damages to surrounding tissues or inorganic material of root canal if be used without precaution. Nowadays the theory of light assisted protocols became another start point for laser in endodontics. Laser has been introduced as an adjuvant to conventional debridement of root canals. We used Medline search engine to collect scientific publications to edit this review article in purpose of revealing the evolution of laser position from an ultimate cleaning methodology to an adjuvant to conventional root canal disinfection protocols.

Limb salvage in fungal osteomyelitis of the post-traumatic lower extremity represents a difficult clinical problem requiring aggressive management. We report lower extremity salvage by radical bony debridement, free tissue transfer, distraction osteogenesis with bone-docking, and a novel antifungal regimen in a clinical setting of infection with Scedosporium inflatum, historically requiring amputation in 100% of cases. We treated Scedosporium inflatum osteomyelitis of the tibia and calcaneus with radical debridement of infected bone, free partial medial rectus abdominis muscle flap coverage, transport distraction osteogenesis, and combination voriconazole/terbinafine chemotherapy, a novel antifungal regimen. We achieved successful control of the infection, limb salvage, and an excellent functional outcome through aggressive debridement of infected bone and soft tissue, elimination of dead space within the bony defect, the robust perfusion provided by the free flap, the hypervascular state induced by distraction osteogenesis, and the synergism of the novel antifungal regimen.

Life-threatening cervical complications associated with infectious mononucleosis are rare. The combination of acute epiglottitis and subsequent necrotizing fasciitis of the head and neck in a patient with infectious mononucleosis has not been reported to date.A 47-year-old female with infectious mononucleosis and epiglottitis was admitted to hospital for i.v. therapy. Owing to her poor clinical condition and the spread of the infection to the throat and superior mediastinum, as evidenced by CT, a cervical debridement was performed. After cervical debridement, histological findings were consistent with necrotizing fasciitis. The bacteria identified were Streptococcus viridans, Veilonella spp. and Capnocytophaga spp. The patient was hospitalized for 33 days.Mononucleosis, usually a benign condition, may be associated with life-threatening septic complications in the neck and chest. Serial CT or MRI scans are necessary to assess the development of the infection in the deep layers of the neck. Rapid medical treatment, extensive surgical debridement and intensive care are vital.

To explore the clinical effects of ipsilateral lower trapezius myocutaneous flap for repairing cervical ulcer as a result of radiotherapy after radical mastectomy. Six patients with cervical ulcers as a result of radiotherapy after radical mastectomy were hospitalized from March 2010 to February 2015, suffering from persistent pain in different degrees. The wound area ranged from 6 cm × 4 cm to 10 cm × 6 cm before debridement, 8 cm × 5 cm to 16 cm × 10 cm after debridement. Ipsilateral lower trapezius myocutaneous flap was used to repair the wound after thorough debridement, with the area ranging from 10 cm × 7 cm to 20 cm × 13 cm. The donor sites were sutured directly or covered with medium-thickness skin graft obtained from the back. Pain was obviously relieved in all the patients 2 days after surgery. The wounds in five patients were healed, while necrosis of superficial skin approximately 1 cm in diameter appeared at the distal end of one myocutaneous flap, and it healed after dressing change. During the follow-up period of 3 to 18 months, no recurrence of ulcer was found, the texture of the myocutaneous flaps was soft with good appearance, and the donor sites healed well. On the basis of thorough debridement, it is feasible to repair the cervical ulcer as a result of radiotherapy after radical mastectomy with the ipsilateral lower trapezius myocutaneous flap.

Arthroscopic debridement has been a gold standard procedure for anterior ankle impingement, both in cases of osseous and soft tissue impingement. There is sparse literature on comparative outcome with respect to functional results between the two types of impingement post-arthroscopic debridement. Our study included 14 patients diagnosed as cases of anterior ankle impingement on the basis of clinical and radiological examination. They were segregated into two groups (on the basis of cause of impingement (osseous versus soft tissue)). Both groups were treated by arthroscopic debridement. Primary outcome was patient satisfaction, which was assessed by Likert scale and clinical outcomes were measured using AOFAS ankle-hind foot scale, VAS score, range of motion and time to return to pre-injury activity level in both groups. Mean follow-up was of 15 months where eleven patients reported an excellent recovery, two patients had good recovery while one patient reported poor outcome. Mean AOFAS ankle hind foot scale improved from 50.5 preoperatively to 85.71 postoperatively (statistically significant; p value - 0.0001). Mean Likert scale value post-operative was 4.21. VAS score showed significant improvement in patients of both the groups. Range of motion was slightly better in soft tissue impingement type with a relatively shorter time to return to sports or preinjury activity level as compared to osseous impingement group. The patients in both the groups had comparable outcomes with no statistically significant difference with regard to patient satisfaction and clinical outcome.

The effects of rapid enzymatic debridement of deep partial-thickness burns with Debrase on wound reepithelialization in swine.

Reepithelialization of deep burns requires spontaneous or active removal or debridement of the necrotic eschar, as recently defined by the American Burn Association. Debrase is a bromelain-derived enzymatic preparation that has been shown to result in rapid and selective debridement of human and animal burns. The authors hypothesized that rapid debridement of deep dermal burns with Debrase would result in earlier reepithelialization of the remaining dermis in a porcine model. Eighty deep dermal contact burns measuring 10 by 20 mm were created on the back and flanks of anesthetized domestic pigs (25 kg) using a brass template preheated in boiling water (100 degrees C) that was applied to the skin for a period of 30 seconds. The template was applied using a spring-loaded device designed to control the amount of pressure applied to the skin by the template. Burns were randomized to a 4-hour topical application of Debrase (lyophilized dry enzyme dissolved and activated in a hydrating vehicle) (n = 40) or its hydrating vehicle (n = 40) followed by daily application of a petrolatum-based antibiotic ointment. Wounds were visually assessed and photographed daily. Four-millimeter full-thickness punch biopsies were obtained for histological analysis using hematoxylin and eosin staining by a board-certified dermatopathologist masked to burn therapy at 7, 11, 13, and 15 days after injury. The primary outcome was the percentage of the burns that were completely reepithelialized at each time point. Secondary outcomes were time to complete reepithelialization and the mean percentage of reepithelialization on microscopic analysis. A sample of 40 burns in each group had 80% power to detect a 20% difference in the percentage of completely reepithelialized burns (two tailed, P < .05). The percentage of completely reepithelialized burns was higher for Debrase than control burns at days 11 (40.9% vs 3.1%; P = .002), 13 (87.5% vs 50%; P = .007), and 15 (97.5% vs 77.5%, P = .018). The mean (SD) percentage reepithelialization of Debrase-treated burns at 7 days was higher than of control burns (47.6% [3.2] vs 0% [0]; P < .001). A larger number of cells in the epidermis and dermis of debrided burns stained positive for the proliferation antigen Ki-67. There was no evidence of any adverse events in the normal skin adjacent to the Debrase-treated burns. Rapid enzymatic debridement of deep partial-thickness burns with Debrase results in earlier reepithelialization and cellular proliferation in swine, when compared with carrier and topical antibiotic dressings alone.

Knee arthrodesis with lengthening: experience of using Ilizarov techniques to salvage large asymmetric defects following infected peri-articular fractures.

PubMed

Barwick, Thomas W; Montgomery, Richard J

We present four patients with large bone defects due to infected internal fixation of knee condylar fractures. All were treated by debridement of bone and soft tissue and stabilisation with flap closure if required, followed by bone transport arthrodesis of the knee with simultaneous lengthening. Four patients (three male and one female), mean age 46.5 years (37-57 years), with posttraumatic osteomyelitis at the knee (three proximal tibia and one distal femur) were treated by debridement of infected tissue and removal of internal fixation. Substantial condylar bone defects resulted on the affected side of the knee joint (6-10 cm) with loss of the extensor mechanism in all tibial cases. Two patients required muscle flaps after debridement. All patients received intravenous antibiotics for at least 6 weeks. Bone transport with a circular frame was used to achieve an arthrodesis whilst simultaneously restoring a functional limb length. In three cases a 'peg in socket' docking technique was fashioned to assist stability and subsequent consolidation of the arthrodesis. Arthrodesis of the knee, free of recurrent infection, was successfully achieved in all cases. None has since required further surgery. Debridement to union took an average of 25 months (19-31 months). The median number of interventions undertaken was 9 (8-12). Two patients developed deep vein thrombosis (DVT), one complicated by PE, which delayed treatment. Two required surgical correction of pre-existent equinus contracture using frames. The median limb length discrepancy (LLD) at the end of treatment was 3 cm (3-4 cm). None has required subsequent amputation. Bone loss and infection both reduce the success rate of any arthrodesis. However, by optimising the host environment with eradication of infection by radical debridement, soft-tissue flaps when necessary and bone transport techniques to close the defect, one can achieve arthrodesis and salvage a useful limb. The residual LLD can result from not accounting for later impaction at peg and socket sites, which had the effect of increasing LLD beyond the desirable amount. We therefore recommend continuing the lengthening for an additional 1-2 cm to allow for this. Copyright © 2013 Elsevier Ltd. All rights reserved.

2006-01-01

The erbium-doped:yttrium, aluminum, and garnet (Er:YAG) laser is considered a useful tool for subgingival debridement because the laser treatment creates minimal damage to the root surface and has potential antimicrobial effects. The aim of this randomized controlled clinical trial was to evaluate clinical and microbiologic effects of pocket debridement using an Er:YAG laser in patients during periodontal maintenance. Twenty patients at a recall visit for maintenance were consecutively recruited if presenting at least four teeth with residual probing depth (PD) > or = 5 mm. Two pockets in each of two jaw quadrants were randomly assigned to subgingival debridement using 1) an Er:YAG laser (test) or 2) an ultrasonic scaler (control). The laser beam was set at 160 mJ with a pulse frequency of 10 Hz. Clinical variables were recorded at baseline, 1 month, and 4 months after treatment. Primary clinical outcome variables were changes in PD and clinical attachment level (CAL). Microbiologic analysis of subgingival samples was performed at baseline, 2 days, and 30 days after treatment using a checkerboard DNA-DNA hybridization technique against 12 periodontal disease-associated species. The mean initial PD was 6.0 mm (SD: 1.2) in the test group and 5.8 mm (SD: 0.9) in the control group. At 1 month post-treatment, the PD reduction was significantly greater for test than control sites (0.9 versus 0.5 mm; P <0.05). The CAL gain also was significantly greater (0.5 versus 0.06 mm; P <0.01). At the 4-month examination, no significant differences were detected in PD reduction (1.1 versus 1.0 mm) or CAL gain (0.6 versus 0.4 mm). Both treatments resulted in reduction of the subgingival microflora. No significant differences in microbiologic composition were identified between the treatment groups at various time intervals. Degree of treatment discomfort scored significantly lower for the test than the control treatment modality. The results of the trial failed to demonstrate any apparent advantage of using an Er:YAG laser for subgingival debridement, except less treatment discomfort perceived by the patients.

Maggot Debridement Therapy in Disaster Medicine.

When disaster strikes, the number of patients requiring treatment can be overwhelming. In low-income countries, resources to assist the injured in a timely fashion may be limited. As a consequence, necrosis and wound infection in disaster patients is common and frequently leads to adverse health outcomes such as amputations, chronic wounds, and loss of life. In such compromised health care environments, low-tech and cheap wound care options are required that are in ready supply, easy to use, and have multiple therapeutic benefits. Maggot debridement therapy (MDT) is one such wound care option and may prove to be an invaluable tool in the treatment of wounds post-disaster. This report provides an overview of the wound burden experienced in various types of disaster, followed by a discussion of current treatment approaches, and the role MDT may play in the treatment of complex wounds in challenging health care conditions. Maggot debridement therapy removes necrotic and devitalized tissue, controls wound infection, and stimulates wound healing. These properties suggest that medicinal maggots could assist health care professionals in the debridement of disaster wounds, to control or prevent infection, and to prepare the wound bed for reconstructive surgery. Maggot debridement therapy-assisted wound care would be led by health care workers rather than physicians, which would allow the latter to focus on reconstructive and other surgical interventions. Moreover, MDT could provide a larger window for time-critical interventions, such as fasciotomies to treat compartment syndrome and amputations in case of life-threatening wound infection. There are social, medical, and logistic hurdles to overcome before MDT can become widely available in disaster medical aid. Thus, research is needed to further demonstrate the utility of MDT in Disaster Medicine. There is also a need for reliable MDT logistics and supply chain networks. Integration with other disaster management activities will also be essential. In the aftermath of disasters, MDT could play an important role facilitating timely and efficient medical treatment and improving patient outcomes. Existing social, medical, and logistic barriers will need to be overcome for MDT to be mainstreamed in Disaster Medicine.

Osteochondral defects (OCDs) of the talus usually affect athletic patients. The primary surgical treatment consists of arthroscopic debridement and microfracture. Various possibilities have been suggested to improve the recovery process after debridement and microfracture. A potential solution to obtain this goal is the application of pulsed electromagnetic fields (PEMFs), which stimulate the repair process of bone and cartilage. The use of PEMFs after arthroscopic debridement and microfracture of an OCD of the talus leads to earlier resumption of sports and an increased number of patients that resume sports. Randomized controlled trial; Level of evidence, 1. A total of 68 patients were randomized to receive either PEMFs (n = 36) or placebo (n = 32) after arthroscopic treatment of an OCD of the talus. The primary outcomes (ie, the number of patients who resumed sports and time to resumption of sports) were analyzed with Kaplan-Meier curves as well as Mann-Whitney U, chi-square, and log-rank tests. Secondary functional outcomes were assessed with questionnaires (American Orthopaedic Foot and Ankle Society ankle-hindfoot score, Foot and Ankle Outcome Score, EuroQol, and numeric rating scales for pain and satisfaction) at multiple time points up to 1-year follow-up. To assess bone repair, computed tomography scans were obtained at 2 weeks and 1 year postoperatively. Almost all outcome measures improved significantly in both groups. The percentage of sport resumption (PEMF, 79%; placebo, 80%; P = .95) and median time to sport resumption (PEMF, 17 weeks; placebo, 16 weeks; P = .69) did not differ significantly between the treatment groups. Likewise, there were no significant between-group differences with regard to the secondary functional outcomes and the computed tomography results. PEMF does not lead to a higher percentage of patients who resume sports or to earlier resumption of sports after arthroscopic debridement and microfracture of talar OCDs. Furthermore, no differences were found in bone repair between groups. Netherlands Trial Register NTR1636. © 2016 The Author(s).

Recent conflicts have been characterised by the use of improvised explosive devices causing devastating injuries, including heavily contaminated wounds requiring meticulous surgical debridement. After being rendered surgical clean, these wounds are dressed and the patient transferred back to the UK for on-going treatment. A dressing that would prevent wounds from becoming colonised during transit would be desirable. The aim of this study was to establish whether using nanocrystalline silver dressings, as an adjunct to the initial debridement, would positively affect wound microbiology and wound healing compared to standard plain gauze dressings. Patients were prospectively randomised to receive either silver dressings, in a nanocrystalline preparation (Acticoat™), or standard of care dressings (plain gauze) following their initial debridement in the field hospital. On repatriation to the UK microbiological swabs were taken from the dressing and the wound, and an odour score recorded. Wounds were followed prospectively and time to wound healing was recorded. Additionally, patient demographic data were recorded, as well as the mechanism of injury and Injury Severity Score. 76 patients were recruited to the trial between February 2010 and February 2012. 39 received current dressings and 37 received the trial dressings. Eleven patients were not swabbed. There was no difference (p=0.1384, Fishers) in the primary outcome measure of wound colonisation between the treatment arm (14/33) and the control arm (20/32). Similarly time to wound healing was not statistically different (p=0.5009, Mann-Whitney). Wounds in the control group were scored as being significantly more malodorous (p=0.002, Mann-Whitney) than those in the treatment arm. This is the first randomised controlled trial to report results from an active theatre of war. Performing research under these conditions poses additional challenges to military clinicians. Meticulous debridement of wounds remains the critical determinant in wound healing and infection and this study did not demonstrate a benefit of nanocrystaline silver dressing in respect to preventing wound colonisation or promoting healing, these dressings do however seem to significantly reduce the unpleasant odour commonly associated with battlefield wounds.

The Morel-Lavallée lesion is one of the concomitant soft tissue lesions of pelvic fractures. Its role in spine fractures and its treatment in combination with osteosynthesis of pelvic or spine fractures have not yet been determined. The aim of this study was to analyse the best diagnostic and treatment options of both spine and pelvic fractures combined with Morel-Lavallée lesions (MLL). An analysis of the literature was performed via PubMed and Medline. This revealed a total of 197 studies and case reports. After analysing the literature, 19 studies/case reports met our inclusion criteria. There are several diagnostic options for MLL, including ultrasound, computed tomography or MRI. In spinal and pelvic lesions, ultrasound is capable of detecting MLL. Some authors tend to perform open debridement of the MLL, whereas others recommend percutanous treatment. Open debridement and vacuum-assisted closure are recommended in late diagnosed MLL, where primary suture of the soft tissue is impossible. Fracture fixation should be performed simultaneously to treatment of the MLL. Broad-spectrum cephalosporins combined with an aminoglycoside or piperacilline/tazobactam should be initiated. Radical debridement and drainage are recommended, especially when MLL is diagnosed late. Repeated ultrasound examinations should be performed of the surrounding soft tissue of the fracture. When MLL is diagnosed within 2 days, percutanous fracture and MLL treatment should be performed. After more than 2 days, both fracture and MLL should be treated with open debridement, open fracture fixation and primary suture if possible. Georg Thieme Verlag KG Stuttgart · New York.

A major hurdle in investigating important clinical questions in knee ligament treatment is a lack of valid translational animal models. This study characterizes the effects of partial transection versus synovial debridement of the anterior (cranial) cruciate ligament (ACL) in dogs. A total of 27 adult purpose-bred research hounds underwent surgery and were assessed over the following 8 weeks. Dogs were randomized into the following three ACL status groups: sham control (n = 9), intact ACL with synovial debridement (exposed ACL) (n = 9), and partial transection of the ACL (partial tear ACL) (n = 9). Dogs in the exposed ACL group and partial tear ACL group had significantly (p < 0.05) more severe lameness, pain, effusion, reduced function, and reduced comfortable range of motion compared with controls, with the partial tear ACL group being most severely affected. More severe ACL and whole-joint pathology, and radiographic scores for osteoarthritis were present in the partial tear ACL group compared with exposed and/or sham control group. On the basis of these findings, biologic components of ACL injury (exposed ACL) played a role in whole-joint inflammation, but the clinical and pathological effects were more severe when both biologic and biomechanical components were present (i.e., partial tear ACL). These novel canine models were successfully developed to evaluate partial transection versus synovial debridement of the ACL and these models will be used to evaluate treatment options for acute management of ACL injuries.

This study is aimed to compare the effects of arthroscopic joint debridement over a 5-year period in a clearly defined patient population (only grade III knee osteoarthritis, history < 2 years). A total of 96 patients (50 male and 46 female) underwent arthroscopic knee debridement for knee OA. The main criteria for inclusion were osteoarthritis grade III (Kellgren-Lawrence score) and a maximal history of 2 years. The subjective complaints and the knee-related quality of life were estimated by the KOOS (knee injury and osteoarthritis outcome score). The score increased significantly within the 1 to 3 rd year post operation. After this interval the mean points of the score declined. But after 5 years the KOOS was higher in comparison to the baseline dates. Patients who had undergone conservative treatment at baseline had a significantly different KOOS than patients in the arthroscopy group. Over time, patients in the arthroscopy group had fewer complaints than patients in the conservative treatment group. In both groups, the results decreased over time. A total of 17 patients (17.2 %) needed a conversion to total endoprothetic replacement. The mean time-interval between index operation and conversion was 56.6 (95 % CI 54.4 - 58.4) months. In middle stages of knee OA, arthroscopic joint debridement can effectively reduce subjective complaints. Because this treatment does not stop the process of OA, the improvements decrease over time. © Georg Thieme Verlag KG Stuttgart · New York.

Background: Platelet-rich concentrates are the most widely used regenerative biomaterials. Stimulation and acceleration of soft and hard tissue healing are due to local and continuous delivery of growth factors and proteins, mimicking the needs of the physiological wound healing and reparative tissue processes. This article aims to evaluate the clinical efficacy of open flap debridement (OFD) with or without platelet-rich fibrin (PRF) in the treatment of intrabony defects. Materials and Methods: Twenty subjects with forty intrabony defects were treated with either autologous PRF with open-flap debridement (test, n = 20) or open-flap debridement alone (control, n = 20). Soft tissue parameters included: Plaque index, sulcus bleeding index, probing depth, relative attachment level and gingival marginal level (GML). The hard tissue parameters included-distances from: Cement enamel junction to the base of the defect (CEJ-BOD): Alveolar crest to the base of the defect (AC-BOD): And CEJ to AC. The parameters were recorded at baseline and at 9 months postoperatively calculated using standardized radiographs by image-analysis software. Results: Statistically significant (0.005*) intragroup improvements were seen with all the hard and soft parameters in both test and control groups, except for GML. Statistically significant improvements were seen with the mean defect fill (CEJ-BOD and AC-BOD) (P = 0.003*) when intergroup comparisons were made. Conclusions: Adjunctive use of PRF with OFD significantly improves defect fill when compared to OFD alone. PRF has consistently been showing regenerative potential; it is simple, easy and inexpensive biomaterial compared with bone grafts. PMID:25954068

PurposeExplore the application of endovascular covered stent-graft (SG) placement in femoral pseudoaneurysms in intravenous drug addicts.Materials and MethodsWe evaluated a consecutive series of pseudoaneurysm in intravenous drug addicts treated with SGs from August 2010 to December 2013.Results15 patients with 16 arterial pseudoaneurysms were enrolled in this study. All were males with a mean age of 36.9 years. Hemorrhage was the most common reason (93.8 %) for seeking medical care, and 3 of these patients were in hemorrhagic shock at admission. All patients received broad-spectrum antibiotics, and debridement and drainage were implemented after SG placement. 7 of the 13 cases which had microbiologicmore » results showed mixed infections, while gram-negative bacteria were the major pathogens. Except for 2 patients, who were lost to follow-up, two new pseudoaneurysms formed due to delayed debridement, and one stent thrombosis occurred, none of the remaining cases had SG infection or developed claudication.ConclusionsSG placement controls massive hemorrhage rapidly, gives enough time for subsequent treatment for pseudoaneurysms due to intravenous drug abuse, and reduces the incidence of postoperative claudication. With appropriate broad-spectrum antibiotics and early debridement, the incidence of SG infection is relatively low. It is an effective alternative especially as temporary bridge measure for critical patients. However, the high cost, uncertain long-term prospects, high demand for medical adherence, and the risk of using the conduits for re-puncture call for a cautious selection of patients. More evidence is required for the application of this treatment.« less

Introduction: Fungal osteomyelitis is an uncommon diseases and generally present in an indolent fashion. Isolated bone affection due to fungi are rare and we present one such case with fungal osteomyelitis of terminal phalanx of second toe. Case Report: We present a rare case of fungal osteomyelitis of right second toe in a 30 year old Indian female who presented with swelling of 8 months duration. Diagnosis was based on the histo-pathological report and culture showing Aspergillus growth. The patient was treated with surgical debridement and amphotericin-B was given for 6 weeks after debridement. There was no recurrence one year post surgery. Conclusion: Isolated Aspergillus osteomyelitis of the bone are very rare and mostly seen in immunocompromised patients and larger bones like spine, femur and tibia. Treatment with wound debridement and subsequently followed up with a course of Amphotericin-B for 6 weeks provided good results. There was no recurrence noted at 1 year follow up. Fungi should be kept in mind for differential diagnosis of osteomyelitis and culture should be appropriately ordered. PMID:27298903

Subgingival delivery of oral debriding agents: a proof of concept.

This study is a proof of concept to determine the efficacy of a custom-fabricated tray in placing antimicrobial and debriding agents in the periodontal pockets of persons with active gingival infections. Localized subgingival delivery of antimicrobial and antibiotic agents is routinely employed as adjunctive therapy for the treatment and management ofperiopathogens associated with periodontal disease. Because these delivery techniques often face time constraints and impose temporary restrictions on patient brushing and flossing, a custom-formed prescription dental tray can be used to deliver and maintain medications in periodontal pockets between office visits and without brushing or flossing restrictions. The ability of this tray to maintain sufficient concentrations of medication in the periodontal pockets to have a therapeutic effect is evaluated here with theoretical modeling and practical application. Hydrogen peroxide is an oral debriding agent and oral wound cleanser with antimicrobial properties. The debriding effect of 1.7% hydrogen peroxide gel was tested in vitro on Streptococcus mutans biofilm using glass carriers for collection. Diffusion modeling tested the potential of the customized tray to place hydrogen peroxide gel into the sulcus in the presence of crevicular fluid flow. Changes in periodontal microflora with scanning electron microscopy analysis of in vivo paper point site sampling were analyzed before and after a thin ribbon of 1.7% hydrogen peroxide gel (approximately 0.7 gm) and a subtherapeutic dose (three drops) of Vibramycin (50 mg/5 ml) were placed via Perio Trays into periodontal pockets, ranging from 4-8 mm at daily prescribed intervals for two to five weeks. In vitro results indicate that 1.7% hydrogen peroxide gel breaks down the exopolysaccharide slime and cell walls ofS. mutans, and begins to debride the cells from glass carriers within 10 minutes. Diffusion modeling indicates that hydrogen peroxide can penetrate into the deeper pockets (9 mm), but also its concentration in these deep pockets will increase over wearing time in the absence of degradation by peroxidases and catalase. Site sampling data confirm diffusion modeling results, with evidence that medication delivered with the prescription tray reduced subgingival bacterial loads and enhanced healing of corresponding oral tissues. The prescription Perio Tray effectively placed medication in the gingival sulcus. Mathematical modeling indicated Perio Tray placement of hydrogen peroxide gel in periodontal pockets with depths up to 9 mm over 15 minutes treatment time was theoretically possible. Pathology reports reveal reductions in subgingival bacterial loads and improvements in pretreatment pocket depths of up to 8 mm after 1.7% hydrogen peroxide and Vibramycin Syrup were prescribed for use with the Perio Tray. The in vitro analysis indicating that hydrogen peroxide is the active and effective oral debriding agent needs to be confirmed with additional studies.

The aim of this study was to describe the applicability and report visual outcomes for the treatment of subepithelial fibrosis and anterior stromal scarring in cases of chronic pseudophakic bullous keratopathy (PBK) with epithelial debridement and endothelial keratoplasty (EK) (pre-Descemet endothelial keratoplasty [PDEK]; Descemet membrane endothelial keratoplasty [(DMEK]) using young donor tissue. Prospective, single-centre, interventional study. 6 cases with chronic PBK (> 1 year duration). Case 1 underwent PDEK with glued intraocular lens (IOL) as a single-stage procedure, whereas cases 2 and 3 underwent glued IOL followed by DMEK and PDEK, respectively, as a second-stage procedure. Cases 4 and 6 underwent PDEK, whereas case 5 underwent DMEK. Epithelial debridement was performed in all cases at the time of EK, and young donor grafts were used. The main outcome measures were best spectacle-corrected visual acuity, clearance of corneal scar and haze, central corneal thickness (CCT), specular microscopy, and endothelial cell count (ECC). Postoperatively, all cases demonstrated significant improvement in visual acuity. The mean value of depth of subepithelial haze was 121±71.7 µm and 25.3 ± 19.8 µm in the preoperative and postoperative periods, respectively (p = 0.028). At the 1-month follow-up, the mean preoperative CCT of 676 ± 92.7 µm was reduced to 534.6 ± 21.1µm. At the 6-month follow-up, the mean ECC loss resulting from the procedure was 36.5 ± 10.4%. EK with epithelial debridement performed for the treatment of chronic PBK resulted in significantly improved visual acuity to a functional level, with the clearance of subepithelial fibrosis and anterior stromal scar, in most patients.

The purpose of this study is to investigate the clinical efficacy and feasibility of one-stage posterior focus debridement, fusion, and instrumentation in the surgical treatment of lumbar spinal tuberculosis with kyphosis in children. From December 2007 to May 2012, 13 patients (six males and seven females) suffering from lumbar spinal tuberculosis with kyphosis were admitted. All patients were treated with one-stage posterior focus debridement, fusion, and instrumentation. Then, the clinical efficacy was estimated by statistical analysis based on the data about Frankel grade, the Cobb angle of kyphosis, and erythrocyte sedimentation rate (ESR), which were collected at certain time. The age of all patients ranged from 5 to 13 years (average, 8.8 years). Operation time ranged from 120 to 190 min (average, 165 min). Intraoperative blood loss ranged from 200 to 800 ml (average, 460 ml). All patients were followed up for 24 to 57 months postoperatively (average, 33.5 months). The Cobb angle was changed significantly between preoperation and postoperation (P < 0.05), and there was no significant loss at the last follow-up. The preoperation ESR (62.5 ± 15.7) returned to normal (16.6 ± 8.1) within 3 months postoperatively in all patients (P < 0.05). Bone fusion was achieved within 3-5 months (average, 3.5 months). In the 13 cases, no postoperative severe complications occurred and neurologic function improved in various degrees. The outcomes of follow-up showed that one-stage posterior focus debridement, fusion, and instrumentation can be an effective treatment method for the lumbar spinal tuberculosis with kyphosis in children.

To develop a rabbit model of Acanthamoeba keratitis (AK) as the best method to reproduce the natural course of this disease. To induce AK, infected contact lenses (1000 amoebae/mm2, 90% trophozoites) were placed over the previously debrided corneal surface, in combination with a temporary tarsorrhaphy. Environmental and clinical strains of Acanthamoeba spp. (genotype T4) were used. Three groups (1L, n = 32; 2L-21d, n = 5; 2L-3d, n = 23) were established according to the number of contact lenses used (1L, 1 lens; 2L-21d and 2L-3d, 2 lenses) and the placement day of these (1L, day 1; 2L-21d, days 1 and 21; 2L-3d, days 1 and 3). The infection was quantified by a clinical score system and confirmed using corneal cytology and culture, polymerase chain reaction and histopathologic analysis. The infection rate obtained was high (1L, 87.5%; 2L-21d, 100%; 2L-3d, 82.6%), although no clinical signs were observed in the 50% of the infected animals in group 1L. Among groups, group 2L-3d showed more cases of moderate and severe infection. Among strains, no statistically significant differences were found in the infection rate. In the control eyes, cross infection was confirmed when a sterile contact lens was placed in the previously debrided corneas but not if the eye remained intact. The combination of two infected contact lenses after corneal debridement seems to be an alternative model, clinically and histopathologically similar to its human counterpart, to induce the different AK stages and reproduce the course of the disease in rabbits.

Er:YAG laser (ErL) irradiation has been reported to be effective for treating peri-implant disease. The present study seeks to evaluate morphological and elemental changes induced on microstructured surfaces of dental endosseous implants by high-pulse-repetition-rate ErL irradiation and to determine the optimal irradiation conditions for debriding contaminated microstructured surfaces. In experiment 1, dual acid-etched microstructured implants were irradiated by ErL (pulse energy, 30-50 mJ/pulse; repetition rate, 30 Hz) with and without water spray and for used and unused contact tips. Experiment 2 compared the ErL treatment with conventional mechanical treatments (metal/plastic curettes and ultrasonic scalers). In experiment 3, five commercially available microstructures were irradiated by ErL light (pulse energy, 30-50 mJ/pulse; pulse repetition rate, 30 Hz) while spraying water. In experiment 4, contaminated microstructured surfaces of three failed implants were debrided by ErL irradiation. After the experiments, all treated surfaces were assessed by stereomicroscopy, scanning electron microscopy (SEM), and/or energy-dispersive X-ray spectroscopy (EDS). The stereomicroscopy, SEM, and EDS results demonstrate that, unlike mechanical treatments, ErL irradiation at 30 mJ/pulse and 30 Hz with water spray induced no color or morphological changes to the microstructures except for the anodized implant surface, which was easily damaged. The optimized irradiation parameters effectively removed calcified deposits from contaminated titanium microstructures without causing substantial thermal damage. ErL irradiation at pulse energies below 30 mJ/pulse (10.6 J/cm(2)/pulse) and 30 Hz with water spray in near-contact mode seems to cause no damage and to be effective for debriding microstructured surfaces (except for anodized microstructures).

Spinal brucellosis is a less commonly reported infectious spinal pathology. There are few reports regarding the surgical treatment of spinal brucellosis in existing literature. This retrospective study was conducted to determine the effectiveness of single-stage transforaminal decompression, debridement, interbody fusion, and posterior instrumentation for lumbosacral spinal brucellosis. From February 2012 to April 2015, 32 consecutive patients (19 males and 13 females, mean age 53.7 ± 8.7) with lumbosacral brucellosis treated by transforaminal decompression, debridement, interbody fusion, and posterior instrumentation were enrolled. Medical records, imaging studies, laboratory data were collected and summarized. Surgical outcomes were evaluated based on visual analogue scale (VAS), Oswestry Disability Index (ODI) and Japanese Orthopaedic Association (JOA) scale. The changes in C-reactive protein (CRP) levels, erythrocyte sedimentation rate (ESR), clinical symptoms and complications were investigated. Graft fusion was evaluated using Bridwell grading criteria. The mean follow-up period was 24.9 ± 8.2 months. Back pain and radiating leg pain was relieved significantly in all patients after operation. No implant failures were observed in any patients. Wound infection was observed in two patients and sinus formation was observed in one patient. Solid bony fusion was achieved in 30 patients and the fusion rate was 93.8%. The levels of ESR and CRP were returned to normal by the end of three months' follow-up. VAS and ODI scores were significantly improved (P < 0.05). According to JOA score, surgical improvement was excellent in 22 cases (68.8%), good in 9 cases (28.1%), moderate in 1 case (3.1%) at the last follow-up. Single-stage transforaminal decompression, debridement, interbody fusion, and posterior instrumentation is an effective and safe approach for lumbosacral brucellosis.

Abstract Background. Shock frequently complicates necrotizing fasciitis (NF) caused by group A Streptococcus (GAS) or Staphylococcus aureus. Intravenous immunoglobulin (IVIG) is sometimes administered for presumptive toxic shock syndrome (TSS), but its frequency of use and efficacy are unclear. Methods. Adult patients with NF and vasopressor-dependent shock undergoing surgical debridement from 2010 to 2014 were identified at 130 US hospitals. IVIG cases were propensity-matched and risk-adjusted. The primary outcome was in-hospital mortality and the secondary outcome was median length of stay (LOS). Results. Of 4127 cases of debrided NF with shock at 121 centers, only 164 patients (4%) at 61 centers received IVIG. IVIG subjects were younger with lower comorbidity indices, but higher illness severity. Clindamycin and vasopressor intensity were higher among IVIG cases, as was coding for TSS and GAS. In-hospital mortality did not differ between matched IVIG and non-IVIG groups (crude mortality, 27.3% vs 23.6%; adjusted odds ratio, 1.00 [95% confidence interval, .55–1.83]; P = .99). Early IVIG (≤2 days) did not alter this effect (P = .99). Among patients coded for TSS, GAS, and/or S. aureus, IVIG use was still unusual (59/868 [6.8%]) and lacked benefit (P = .63). Median LOS was similar between IVIG and non-IVIG groups (26 [13–49] vs 26 [11–43]; P = .84). Positive predictive values for identifying true NF and debridement among IVIG cases using our algorithms were 97% and 89%, respectively, based on records review at 4 hospitals. Conclusions. Adjunctive IVIG was administered infrequently in NF with shock and had no apparent impact on mortality or hospital LOS beyond that achieved with debridement and antibiotics. PMID:28034881

To evaluate the efficacies of arthroscopic debridement and removal of osteophyma for olecroanon and olecranon fossa plasty for posterior impingement of elbow joint. Between 1999 and 2008, a total of 21 cases were diagnosed with osteoarthritis and posterior elbow impingement. There were 15 males and 6 females. And there were 16 right and 15 left cases. They included volleyball players (n = 7), tennis players (n = 7), golf enthusiasts (n = 4) and fencers (n = 3). The average duration of onset-operation was 3.5 years (range: 2.5 - 8). Arthroscopic exploration revealed synovial hyperplasia hypertrophy, cartilage degeneration and olecranon fossa hyperplasia with deformed olecranon fossa. Debridement and plasty were performed. Loose bodies were removed from elbow joint in 6 patients. Partial resection of posterior olecranon tip was performed and osteophytes or fibrous tissue removed in this area. Dynamic observation showed no posterior elbow impingement. Postoperative follow-up was conducted in 19 cases and 2 cases became lost to follow-up. The average follow-up period was 25.3 months (range: 18 - 42). All patients were evaluated preoperatively and postoperatively with the Hospital for Special Surgery Elbow Assessment Scale. The outcomes were excellent (n = 12), good (n = 7) and fair (n = 2). Postoperative patients elbow swelling and pain relieve, sports and life function returns to normal, elbow flexion and rotating mobility obviously improved. With the elbow radiological films to measure the range of motion, the average range of motion was 90.5° preoperatively and improved to 130° postoperatively. There was significant improvement in all cases. Posterior elbow impingement is caused by hyperextension trauma and elbow overuse during specific sporting activities. Arthroscopic debridement and olecroanon or olecranon fossa plasty demonstrates excellent results for posterior impingement of elbow joint.

Traumatic gas gangrene is a fatal infection mainly caused by Clostridium perfringens. It is a challenge to manage gas gangrene in open wounds and control infection after debridement or amputation. The aim of the present study was to use vacuum sealing drainage (VSD) with continuous irrigation of potassium permanganate to manage infective wounds of gas gangrene and observe its clinical efficacy. A total of 48 patients with open traumatic gas gangrene infection were included in this study. Amputations were done for 27 patients, and limb salvage procedures were performed for the others. After amputation or aggressive debridement, the VSD system, including polyvinyl alcohol (PVA) foam dressing and polyurethane (PU) film, with continuous irrigation of 1:5000 potassium permanganate solutions, was applied to the wounds. During the follow-up, all the patients healed without recurrence within 8-18 months. There were four complications. Cardiac arrest during amputation surgery occurred in one patient who suffered from severe septic shock. Emergent resuscitation was performed and the patient returned to stable condition. One patient suffered from mixed infection of Staphylococcal aureus, and a second-stage debridement was performed. One patient suffered from severe pain of the limb after the debridement. Exploratory operation was done and the possible reason was trauma of a local peripheral nerve. Three cases of crush syndrome had dialysis treatment for concomitant renal failure. In conclusion, VSD can convert open wound to closed wound, and evacuate necrotic tissues. Furthermore, potassium permanganate solutions help eliminate anaerobic microenvironment and achieve good therapeutic effect on gas gangrene and mixed infection. VSD with continuous irrigation of potassium permanganate is a novel, simple and feasible alternative for severe traumatic open wounds with gas gangrene infection.

The objective of this randomized, controlled clinical trial was to compare the clinical and microbiological effects of pocket debridement using erbium-doped: yttrium, aluminium and garnet (Er:YAG) laser with conventional debridement in maintenance patients. Fifteen patients, all smokers, having at least four teeth with residual probing depth (PD) ≥ 5 mm were recruited. Two pockets in two jaw quadrants were randomly assigned to subgingival debridement using an Er:YAG laser (test) or ultrasonic scaler/curette (control) at 3-month intervals. Relative attachment level (RAL), PD, bleeding on probing and dental plaque were recorded at baseline and at 6 and 12 months. Microbiological subgingival samples were taken at the same time points and analysed using a checkerboard DNA-DNA hybridization technique. A significant decrease in PD took place in both treatments from baseline to 12 months (p < 0.01). In the control, the mean initial PD decreased from 5.4 to 4.0 mm at 12 months. For the test, a similar decrease occurred. No significant between-treatment differences were shown at any time point. The mean RAL showed no overall significant inter- or intra-treatment differences (p > 0.05). No significant between-treatment differences were observed in subgingival microbiological composition or total pathogens. The results failed to support that an Er:YAG laser may be superior to conventional debridement in the treatment of smokers with recurring chronic inflammation. This appears to be the first time that repeated Er-YAG laser instrumentation has been compared with mechanical instrumentation of periodontal sites with recurring chronic inflammation over a clinically relevant time period. © 2012 John Wiley & Sons A/S.

The objective was to evaluate CO2 laser debridement of the cricoarytenoid joint (CAJ) combined with prosthetic laryngoplasty to prevent post-operative loss of arytenoid abduction in seven horses. Horses were assigned to either laser debridement of the left CAJ and laryngoplasty (laser treated, n=5) or control laryngoplasty (sham, n=2), and were evaluated with endoscopic examinations and measurement of right to left angle quotients (RLQ) to assess maintenance of arytenoid abduction. The animals were euthanased at intervals after surgery and larynges were harvested for post-mortem testing, including determination of translaryngeal flow, pressure, impedance and RLQ. Measurements were obtained under increasing vacuum-generated negative pressure with laryngoplasty sutures intact and with the knot/crimp of the laryngoplasty sutures removed. Following post-mortem testing the cricoarytenoid joints were examined histologically. Post-operative endoscopic examinations revealed no significant differences between RLQ measurements calculated for day 1 following surgery to the termination date of the study for the seven horses. Post-mortem RLQ at airflows of 10 and 60 L/s was significantly higher in sham than in laser treated horses both before and after knot/crimp removal. Translaryngeal impedance at 10 and 60 L/s was not statistically different between groups. Histopathology revealed necrosis and loss of articular cartilage in the laser treated horses. The lymphoid cell infiltration subsided but joint capsule and periarticular fibrosis increased over the course of the study. Post-operative loss of arytenoid abduction after laryngoplasty can be minimized with CO2 laser debridement of the CAJ joint. Copyright © 2013 Elsevier Ltd. All rights reserved.

Purpose To investigate the effect of the Cdk5 inhibitor olomoucine on corneal debridement wound healing in vivo. Methods Corneal debridement wounds of 1.5 mm were made on the ocular surface of CD-1 mice. A 20 μl drop of 15 µM olomoucine in 1% DMSO was applied to the wound area immediately after wounding and again after 6 h. Control mice received identical applications of 1% DMSO. Mice were euthanized after 18 h, two weeks, and three weeks for evaluation of wound healing and restratification. Corneas were stained with Richardson’s dye, photographed, and processed for histology and immunofluorescence as whole mounts or paraffin sections. The remaining wound area at 18 h was measured by image analysis. Scratch wounded cultures of human corneal-limbal epithelial cells (HCLE) were used to examine the effect of olomoucine on matrix metalloproteinase (MMP) expression in vitro. MMP-2 and MMP-9 were detected by immunofluorescence and immunoblotting. Results Olomoucine treatment significantly enhanced corneal wound closure without increasing inflammation or infiltration of polymorphonuclear leukocytes 18 h after wounding (p<0.05). The increased localization of MMP-9 within epithelial cells at the wound edge was further enhanced by olomoucine while the expression of MMP-2 was reduced. Olomoucine treatment of scratch wounded HCLE cells produced similar changes in MMP-9 and MMP-2 expression. The examination of treated corneas two and three weeks after wounding showed normal epithelial restratification with no evidence of inflammation or stromal disorganization. Conclusions Topical application of olomoucine in 1% DMSO significantly enhances closure of small epithelial debridement wounds without increasing inflammation or impairing reepithelialization.

Direct percutaneous endoscopic necrosectomy has been described as a minimally invasive intervention for the debridement of walled-off pancreatic necrosis (WOPN). In this retrospective cohort study, we aimed to confirm these findings in a US referral center and evaluate the clinical value of this modality in the treatment of pancreatic necrosis as well as other types of intra-abdominal fluid collections and necrosis. Twelve consecutive patients with WOPN or other abdominal abscess requiring debridement and washout underwent computed tomography (CT)-guided drainage catheter placement. Each patient then underwent direct percutaneous endoscopic necrosectomy and washout with repeat debridement performed until complete. Drains were then removed once output fell below 30 mL/day and imaging confirmed resolution. The primary endpoints were time to clinical resolution and sustained resolution at 1-year follow up.  Ten patients were treated for WOPN, one for necrotic hepatic abscesses, and one for omental necrosis. The median time to intervention was 85 days with an average of 2.3 necrosectomies performed. Complete removal of drains was accomplished in 11 patients (92 %). The median time to resolution was 57 days. No serious adverse events occurred; however, one patient developed pancreaticocutaneous fistulas. Ten patients completed 1-year surveillance of which none required drain replacement. No patients required surgery or repeat endoscopy. This series supports the premise that direct percutaneous endoscopic necrosectomy is a safe and effective intervention for intra-abdominal fluid collections and necrosis in appropriately selected patients. Our study demonstrates a high clinical success rate with minimal adverse events. This modality offers several potential advantages over surgical and transgastric approaches including use of improved accessibility, an excellent safety profile, and requirement for only deep or moderate sedation.

An anterior approach for debridement and fusion with autologous bone graft has been recommended as the gold standard for surgical treatment of pyogenic spondylodiscitis. The use of anterior foreign body implants at the site of active infection is still a challenging procedure for spine surgeons. Several authors have recently introduced anterior grafting with titanium mesh cages instead of autologous bone strut in the treatment of spondylodiscitis. The authors present their experience of anterior fusion with 3 types of cages followed by posterior pedicle screw fixation. They also compare their results with the use of autologous iliac bone strut. The authors retrospectively reviewed the cases of 60 patients with pyogenic spondylodiscitis treated by anterior debridement between January 2003 and April 2005. Fusion using either cages or iliac bone struts was performed during the same course of anesthesia followed by posterior fixation. Twenty-three patients underwent fusion with autologous iliac bone strut, and 37 patients underwent fusion with 1 of the 3 types of cages. The infections resolved in all patients, as noted by normalization of their erythrocyte sedimentation rates and C-reactive protein levels. Patients in both groups were evaluated in terms of their preoperative and postoperative clinical and imaging findings. Single-stage anterior debridement and cage fusion followed by posterior pedicle screw fixation can be effective in the treatment of pyogenic spondylodiscitis. There was no difference in clinical and imaging outcomes between the strut group and cage group except for the subsidence rate. The subsidence rate was higher in the strut group than in the cage group. The duration until subsidence was also shorter in the strut group than in the cage group.

Debridement of the burn eschar is a cornerstone of burn wound care. Rapid enzymatic debridement with a bromelain-based agent (Debriding Gel Dressing-DGD) has recently been investigated. The current study was designed to further investigate the selectivity of DGD to burned eschar in a larger number and more varied types of wounds. A systematic animal experiment was conducted to determine the effects of DGD on normal, non-injured skin, burns, exposed dermis of donor sites, and skin punch biopsy wells. Partial thickness dermal burns and partial thickness skin graft donor sites were created on a pig and treated with a 4-h application of DGD or its control hydrating vehicle that does not have any activity except hydration. Punch biopsy samples were taken before and after treatment and microscopically assessed for evidence of tissue viability and its respective components thickness. Rapid dissolution of the burn eschar was noted in all DGD but not vehicle treated burns. There was no apparent damage to the underlying sub eschar dermis, donor sites, normal skin or punch biopsy wells after exposure to DGD. While the thickness of the treated tissues slightly increased due to edema, the increase in dermal thickness was similar after treatment with DGD or its vehicle. The increase in the cross section surface area of the treated punch biopsy wells was similar after treatment with DGD and its control vehicle. Exposure of the burn eschar to DGD results in its rapid dissolution. Exposure of normal skin or non-burned dermis to DGD has no effects demonstrating its selectivity to eschar.

This study sought to compare the root canal debridement ability of Neolix, Reciproc and ProTaper rotary systems in long oval-shaped root canals. Eighty five extracted single-rooted human teeth with long oval-shaped single root canals were selected and divided into three experimental groups(n=25) and one control group (n= 10). Root canals were filled with Vitapex radiopaque contrast medium and prepared with Neolix, Reciproc or ProTaper systems. The control group only received irrigation. Digital radiographs were obtained at baseline and postoperatively and subjected to digital subtraction. The percentage of reduction in contrast medium was quantified at 0-5 mm and 5-10 mm distances from the apex. The data were analyzed using one-way ANOVA and t-test. The mean percentage of the contrast medium removed was not significantly different in the 0-5mm segment among the three groups ( P =0.6). In the 5-10mm segment a significant difference was found in this regard among the ProTaper and Reciproc groups ( P =0.02) and the highest mean percentage of contrast medium was removed by ProTaper. But, difference between ProTaper and Neolix as well as Neolix and Reciproc was not significant. In Neolix ( P =0.024) and Reciproc ( P =0.002) systems, the mean percentage of the contrast medium removed from the 0-5mm segment was significantly greater than that in 5-10mm segment; however, this difference was not significant in ProTaper group ( P =0.069). Neolix single-file system may be a suitable alternative to ProTaper multiple-file system in debridement of long oval shaped canals.

The purpose of this study is to determine the cost-effectiveness of collagenase ointment relative to autolysis with a hydrogel dressing when debriding necrotic pressure ulcers in a long-term care setting. A Markov decision process model with 2 states (necrotic nonviable wound bed transitioning to a granulated viable wound bed) was developed using data derived from a prospective, randomized, 6-week, single-center trial of 27 institutionalized subjects with pressure ulcers that were ≥ 85% necrotic nonviable tissue. Direct medical costs from the payer perspective included study treatments, wound treatment supplies, and nursing time. Clinical benefit was measured as "granulation days" and was derived from the time-dependent debridement rates of the alternative products. The average cost per patient for 42 days of pressure ulcer care was $1,817 in 2012 for the collagenase group and $1,611 for the hydrogel group. Days spent with a granulated wound were 3.6 times higher for collagenase (23.4 vs 6.5) than with the hydrogel. The estimated cost per granulation day was > 3.2 times higher for hydrogel ($249) vs collagenase ($78). In this economic analysis based on a randomized, controlled clinical trial, collagenase ointment resulted in a faster time to complete debridement and was more cost-effective than hydrogel autolysis for pressure ulcers in a long-term care setting. Even though collagenase ointment has a higher acquisition cost than hydrogel, the clinical benefit offsets the initial cost difference, resulting in lower cost per granulation day to the nursing home over the course of the 42-day analysis.

Retrospective analysis of the clinical study efficacy and feasibility of one-stage posterior transforaminal lumbar debridement, 360° interbody fusion, and posterior instrumentation in treating lumbosacral spinal tuberculosis. A total of 21 patients with lumbosacral tuberculosis (TB) collected from January 2004 to January 2010, underwent one-stage posterior transforaminal lumbar debridement, 360° interbody fusion, and posterior instrumentation. In addition, the clinical efficacy was evaluated based on the data on the lumbo-sacral angle, neuro-logical status that was recorded by American Spinal Injury Association (ASIA) Impairment Scale, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP), which were collected at specific time points. All cases were followed up for 16-36 months (average 24.9 ± 6.44 months). 18 patients suffered from evident neurological deficits preoperatively, of which 16 patients returned to normal at the final follow-up. Two patients with neurological dysfunction aggravated postoperative, experienced significant partial neurological recovery. With an effective and standard anti-TB chemotherapy treated, the values of ESR and CRP returned to normal levels 3-month later postoperative and maintained till the final follow-up. Preoperative lumbosacral angle was 20.89 ± 2.32° and returned 29.62 ± 1.41° postoperative. During long-term follow-up, there was only 1-3° lumbosacral angle loss. There was a significant difference between preoperative and postoperative lumbosacral angles. With effective and standard anti-TB chemotherapy, one-stage posterior transforaminal lumbar debridement, 360° interbody fusion, and posterior instrumentation for lumbosacral tuberculosis can effectively relieve pain symptoms, improve neurological function, and reconstruct the spinal stability.

Recently, the occurrence of peri-implantitis has been increasing. However, a suitable method to debride the contaminated surface of titanium implants has not been established. The aim of this study was to investigate the morphological changes of the microstructured fixture surface after erbium laser irradiation, and to clarify the effects of the erbium lasers when used to remove calcified deposits from implant fixture surfaces. In experiment 1, sandblasted, large grit, acid etched surface implants were treated with Er:YAG laser or Er,Cr:YSGG laser at 30-60 mJ/pulse and 20 Hz with water spray. In experiments 2 and 3, the effects of erbium lasers used to remove calcified deposits (artificially prepared deposits on virgin implants and natural calculus on failed implants) were investigated and compared with mechanical debridement using either a titanium curette or cotton pellets. After the various debridement methods, all specimens were analyzed by stereomicroscopy (SM), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Stereomicroscopy and SEM showed that erbium lasers with optimal irradiation parameters did not have an effect on titanium microstructures. Compared to mechanical debridement, erbium lasers were more capable of removing calcified deposits on the microstructured surface without surface alteration using a non-contact sweeping irradiation at 40 mJ/pulse (ED 14.2 J/cm 2 /pulse) and 20 Hz with water spray. These results indicate that Er:YAG and Er,Cr:YSGG lasers are more advantageous in removing calcified deposits on the microstructured surface of titanium implants without inducing damage, compared to mechanical therapy by cotton pellet or titanium curette.

This study aims to describe the incidence of infective complications, including tumour endoprosthesis infection, in a cohort of patients undergoing tumour endoprosthesis surgery in Victoria, Australia. This retrospective cohort study was performed over 15 years (January 1996-December 2010). 121 patients underwent tumour endoprosthesis surgery during the study period. Patients were followed for a median of 34 months (interquartile range [IQR] 17, 80). Overall, 34 patients (28%) experienced infective complications including: bacteraemia in 19 patients (16%) and tumour endoprosthesis infection in 17 (14%). The majority of patients with early and late acute infections (haematogenous) were managed with debridement and retention of the prosthesis in addition to biofilm-active antibiotics. Late chronic infections were predominantly managed by exchange of the prosthesis. The overall success rate of treatment was 71%. The success rate for debridement and retention was 75% compared with 67% for exchange procedures. There is a significant rate of infective complications following tumour endoprosthesis surgery including 14% of patients experiencing infection involving the tumour endoprosthesis. This study is the first to report on outcomes from debridement and retention of the prosthesis; which had comparable success rates to other treatment modalities. Crown Copyright © 2014.

Mozo, Sandra; Llena, Carmen

2012-01-01

Introduction: Effective irrigant delivery and agitation are prerequisites for successful endodontic treatment. Ultrasonic irrigation can be performed with or without simultaneous ultrasonic instrumentation. Existing literature reveals that ultrasonic irrigation may have a very positive effect on chemical, biological and physical debridement of the root canal system as investigated in many in vitro studies. Objective: The purpose of this review article was to summarize and discuss the available information concerning ultrasonic irrigation in endodontics. Methods: This article presents an overview of ultrasonic irrigation methods and their debridement efficacy. In this paper the relevant literature on passive ultrasonic irrigation is reviewed. Information from original scientific papers or reviews listed in MEDLINE and Cochrane were included in the review. Results: The use of ultrasound in the irrigation procedure results in improved canal cleanliness, better irrigant transfer to the canal system, soft tissue debridement, and removal of smear layer and bacteria. There are many in vitro studies, but there is a need to standardize protocols, and correlate the clinical efficacy of ultrasonic devices with improved treatment outcomes. Understanding the basis of ultrasonic irrigation is fundamental for clinicians and researchers to improve the design and use of ultrasonic irrigation. Key words:Ultrasonic irrigation, ultrasound, smear layer, endodontics. PMID:22143738

Teriparatide comprises the first 34 amino acids of parathyroid hormone and is a systemic anabolic agent that is Food and Drug Administration approved for the treatment of osteoporosis but not for periodontitis. To our knowledge, this is the first clinical case report to document the treatment of a patient with severe periodontitis using an open-flap debridement procedure in conjunction with teriparatide. A 45-year-old female patient was diagnosed with severe chronic periodontitis, including the presence of an intrabony defect on tooth #6. She received open-flap debridement surgery in conjunction with daily systemic administration of 20 µg teriparatide, oral vitamin D, and calcium supplements for 6 weeks. Radiographic, clinical, gingival crevicular fluid (pyridinoline cross-linked carboxy-terminal propeptide of type I procollagen, procollagen type 1 N-propeptide, and osteocalcin), and serum parameters (parathyroid hormone, bone alkaline phosphatase, calcium, and 25-hydroxyvitamin D) were assessed. Treatment outcomes were evaluated over 4 years, with successful radiographic and clinical results throughout the follow-up period. Teriparatide administration in conjunction with traditional open-flap debridement surgery offers potential for the treatment of severe intrabony defects resulting from chronic periodontitis.

The purpose of this study is to determine the laser related complication rate for shoulder arthroscopy in the initial clinical experience of 50 patients, and to identify potential advantages of laser use in shoulder arthroscopy. Fifty patients spanning ages 25 to 87 were treated. Surgical debridement was selective and conservative creating a smooth post resection rim. In those that included rotator cuff tears, in addition to arthroscopic debridement, a mini arthrotomy and open acromioplasty were performed. Changes in arthroscopic technique due to laser use included no arthroscopic pump use and use of the shaver only when the fiber could not be easily seen with severe synovitis. We found that the hyper-vascular synovium did not need to be resected last, it could be resected at any point during the procedure. Four hundred and 600 micron fiberoptics were used as well as 20 watts average power. Technical advantage of the laser was felt to be the size of the instrument probe and the availability of excellent hemostasis. Complications include one case of arthroscope damage and one case with a broken fiber tip which was removed with a grasper. Long term follow up of these patients is now underway.

Cartilage debridement is one of the recommended procedures for the management of chondral defects. Radiofrequency probes allow to debride the cartilage, but may induce subchondral bone necrosis. Medline, Cochrane and Google Scholar were searched to identify studies on arthroscopic debridement of the articular cartilage of the knee using radiofrequency chondroplasty. The methodological quality of the studies was assessed using the Coleman methodology score (CMS). Monopolar and bipolar radiofrequency devices provide significantly better clinical outcomes, especially for patients with high-grade chondral lesions, compared with mechanical shaver only. Despite the original concerns regarding subchondral bone necrosis, low complication rates are reported. Heterogeneity in terms of type of device does not allow sound comparison of the published results. There is lack of evidence on the long-term effects of radiofrequency chondroplasty. Study methodology should be improved: the average Coleman methodology score was 56.2 out of 100. More comparative, well-designed and larger cohort trials are needed to ascertain whether radiofrequency chondroplasty offers long-term benefits over other simpler and more economical alternatives. © The Author 2016.

Treating thoracic infective spondylodiscitis with anterior surgical approaches carry a relatively high risk of perioperative and postoperative complications. Posterior approaches have been reported to result in lower complication rates than anterior procedures, but more evidence is needed to demonstrate the safety and efficacy of 1-stage posterior approaches for treating infectious thoracic spondylodiscitis.Preoperative and postoperative clinical data, of 18 patients who underwent 2 types of 1-stage posterior procedures, costotransversectomy and transforaminal thoracic interbody debridement and fusion and 7 patients who underwent anterior debridement and reconstruction with posterior instrumentation, were retrospectively assessed.The clinical outcomes of patients treated with 1-stage posterior approaches were generally good, with good infection control, back pain relief, kyphotic angle correction, and either partial or solid union for fusion status. Furthermore, they achieved shorter surgical time, fewer postoperative complications, and shorter hospital stay than the patients underwent anterior debridement with posterior instrumentation.The results suggested that treating thoracic spondylodiscitis with a single-stage posterior approach might prevent postoperative complications and avoid respiratory problems associated with anterior approaches. Single-stage posterior approaches would be recommended for thoracic spine infection, especially for patients with medical comorbidities.

The process of burn debridement is a challenging technique requiring significant skills to identify the regions that need excision and their appropriate excision depths. In order to assist surgeons, a machine learning tool is being developed to provide a quantitative assessment of burn-injured tissue. This paper presents three non-invasive optical imaging techniques capable of distinguishing four kinds of tissue-healthy skin, viable wound bed, shallow burn, and deep burn-during serial burn debridement in a porcine model. All combinations of these three techniques have been studied through a k-fold cross-validation method. In terms of global performance, the combination of all three techniques significantly improves the classification accuracy with respect to just one technique, from 0.42 up to more than 0.76. Furthermore, a non-linear spatial filtering based on the mode of a small neighborhood has been applied as a post-processing technique, in order to improve the performance of the classification. Using this technique, the global accuracy reaches a value close to 0.78 and, for some particular tissues and combination of techniques, the accuracy improves by 13%.

To assess factors that might predict serious necrotizing soft tissue infections following illicit drug injection. A retrospective review of a consecutive case series. An urban municipal hospital. Thirty patients presenting with cutaneous abscesses resulting from illicit drug injections during a 5-year period. All cases presented clinically with fluctuance, erythema, or induration but required extensive debridement at the time of incision and drainage. Operative treatment employed wide incision, routine subfascial examination, and aggressive debridement. Clinical management included broad-spectrum antibiotics, critical care support, and reconstructive procedures. Mortality, extent of debridement, preoperative vital signs and laboratory values, Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, bacteriologic and pathologic test results. Postoperatively, all patients were housed in the intensive care unit for 8.4 +/- 14.5 days. Six patients died (20%). On arrival at the intensive care unit, systolic blood pressure was 80 mm Hg or less in 2 patients, 1 of whom died. White blood cell count on hospital admission was elevated in 27 of 30 patients (mean, 27.2 +/- 15.3 x 10(9)/L) and 2 patients were identified as having human immunodeficiency virus infection. All patients underwent initial surgery less than 24 hours after admission; following debridement, the average wound size was 276 +/- 238 cm2 (range, 15-783 cm2). Five patients required extremity amputation, and all other survivors underwent reconstruction with skin grafts and/or myocutaneous flaps. All but 1 patient were reexamined in the operating room within 12 hours and underwent an average of 3.1 +/- 1.6 operative procedures. Of those wound cultures obtained in the operating room, there was no pattern to the bacteriologic isolates. Seventeen patients had mixed isolates and 11 had single organisms. Pathologic findings in 20 patients included panniculitis (3 patients), necrotizing fasciitis (11 patients), myositis (6 patients), and osteomyelitis (1 patient). We failed to identify any clinical factor, including temperature, heart rate, systolic blood pressure, white blood cell count, base deficit, albumin level, PO2, or APACHE II score that could predict mortality or the requirement for extensive debridement. Parenteral injections of illicit drugs can produce infections that present with signs of simple cutaneous abscess and yet unpredictably become extensive necrotizing soft tissue infections. Treatment requires a high index of suspicion along with an inquisitive operative approach to avoid missing these potentially serious infections.

Although the incidence of prosthetic infection is low (1%-6%), the consequences (limb loss or death) are dramatic for a patient, with high mortality rate (25%-75%) and limb loss in 40%-75% of cases. In case of Szilagyi's grade III infection, standard procedure consists of the excision of prosthesis and wound debridement. Alternative method is medical treatment. This is a case report of a patient with prosthetic infection of Silver-ring graft, used for femoropopliteal reconstruction, in whom an extreme skin necrosis developed in early postoperative period. This complication was successfully treated medically. After repeated debridement and wound-packing, the wound was covered using Thiersch skin graft.

Aspergillus septic arthritis is a rare and serious medical and surgical problem. It occurs mainly in immunocompromised patients. Aspergillus fumigatus is the most common causative organism followed by Aspergillus flavus. The most common site affected is knee followed by shoulder, ankle, wrist, hip and sacroiliac joint. Debridement and voriconazole are primary treatment of articular aspergilosis. To the best of our knowledge, there are no reported cases of co-infection of tuberculosis (TB) and Aspergillus infecting joints. We report a case of co-infection of TB and A. flavus of hip and knee of a 60-year-old male, with type 2 diabetes mellitus. He was treated with debridement, intravenous voriconazole, and antitubercular drugs. PMID:27293296

Mucormycosis as a consequence of trauma is a devastating complication; these infections are challenging to control, with a fatality rate approaching 96% in immunocompromised patients. We present a case where a proactive approach was successfully employed to treat mucormycosis following complex polytrauma. Aggressive repeated surgical debridement, in combination with appropriate antifungal therapy, proved successful in this instance. In our opinion, mucormycosis in trauma mandates an aggressive surgical approach. This prevents ascending dissemination of mucormycosis and certainly reduces the risk of patient mortality as a direct result. Anti-fungal therapy should be used secondarily as an adjunct together with surgical debridement, or as an alternative when surgical intervention is not feasible.

Onset of chronic periodontitis is associated with an aberrant polymicrobial community, termed dysbiosis. Findings regarding its etiology obtained using high-throughput sequencing technique suggested that dysbiosis holds a conserved metabolic signature as an emergent property. The purpose of this study was to identify robust biomarkers for periodontal inflammation severity. Furthermore, we investigated disease-associated metabolic signatures of periodontal microbiota using a salivary metabolomics approach. Whole saliva samples were obtained from adult subjects before and after removal of supragingival plaque (debridement). Periodontal inflamed surface area (PISA) was employed as an indicator of periodontal inflammatory status. Based on multivariate analyses using pre-debridement salivary metabolomics data, we found that metabolites associated with higher PISA included cadaverine and hydrocinnamate, while uric acid and ethanolamine were associated with lower PISA. Next, we focused on dental plaque metabolic byproducts by selecting salivary metabolites significantly decreased following debridement. Metabolite set enrichment analysis revealed that polyamine metabolism, arginine and proline metabolism, butyric acid metabolism, and lysine degradation were distinctive metabolic signatures of dental plaque in the high PISA group, which may be related to the metabolic signatures of disease-associated communities. Collectively, our findings identified potential biomarkers of periodontal inflammatory status and also provide insight into metabolic signatures of dysbiotic communities. PMID:28220901

Surgery complemented by antibiotics forms the backbone of the successful management of necrotizing fasciitis. But it will be very difficult to clear away extensive necrotizing tissue thoroughly in critically ill patients when their vital signs are unstable. The authors report the case of a 33-year-old woman who had extensive necrotizing fasciitis of the right lower limb with septic shock. The patient was severely anemic and malnutrition and had been given conservative debridement at bedside, that is, only detached necrotizing tissues was taken away while some other necrotizing tissue still remained, so that the skin tissue within the same area could be saved as much as possible. After debridement, negative pressure was applied at 125 mm Hg. Broad-spectrum antibiotics and effective supplementation were also complemented, thus controlling the septic shock. All necrotizing tissues were detached, and the sparing vital skin on necrotizing fascia was preserved successfully after negative pressure treatment. The patient was finally saved. In conclusion, negative pressure treatment may help diminish toxin absorbance, detach gangrene tissue, and preserve sparing vital tissue. This case suggests the value of combined use of negative pressure therapy and conservative debridement in critically ill patients with extensive necrotizing fasciitis. © The Author(s) 2014.

In developing countries, during the harvest season, winnower blade injuries occur very frequently in children and results in lifelong disability. Nine children were managed during 1 month, all resulting due to winnower blade induced craniofacial trauma. PubMed search for “fan blade injury” showed two case series and three case reports. In our study, 88% had compound depressed fracture; brain matter leak in 56%, cerebrospinal fluid (CSF) leak alone in 22%. 66.7% had injury involving the frontal bone. Two patients had eye injury with visual loss. Seven underwent debridement craniectomy, five augmentation duroplasty and three contusectomy. All had vegetable material, sand particles. Complications in 66.6% with two cases of CSF leak settled with lumbar drain, one case of CSF otorrohea, 22.2% of wound infection, 44.4% wound dehiscence requiring redebridement and suturing in five patients. Two patients had postoperative seizures, two patients had hemiparesis both improved. Two low Glasgow Coma Scale remained so on postoperative period. One case of subdural empyema needed debridement and duroplasty with glue. No mortality noted. These findings were consistent with previous reports. Follow-up at 1.5 months showed good functional recovery. Early surgery debridement, steps to minimize postoperative infections, identifying putative risk factors early in the management are the principles of a successful treatment regimen. PMID:29682010

2018-01-01

Invasive fungal sinusitis is a morbid pathology that typically affects immunocompromised patients and may quickly progress to fulminant disease. The purpose of this study was to measure the sensitivity and specificity of touch preparation of nasal debridement specimens as a rapid diagnostic tool for invasive fungal sinusitis. A retrospective chart review was performed of 22 patients undergoing nasal debridement due to suspicion for invasive fungal sinusitis over a 10-year period. Thirteen patients had touch preparation of nasal specimens followed by routine histologic processing; 2 of these patients underwent two and 1 patient had three separate debridements, for a total of 17 touch preparations performed. The sensitivity and specificity of touch preparation were calculated by correlating the initial results with the presence of fungal invasion on final pathologic analysis. The sensitivity of touch preparation was 56% (95% confidence interval [CI]: 0.23 to 0.85), specificity was 100% (95% CI: 0.60 to 1.00), positive predictive value was 100% (95% CI: 0.46 to 1.00), and negative predictive value was 67% (95% CI: 0.35 to 0.89). This procedure may be a useful adjunct in situations requiring rapid diagnosis of invasive fungal sinusitis but should not be used as the sole criterion for determining the need for surgical intervention.

This is an exemplary case report underlining a relevant morbidity which could be associated to the use of autologous iliac crest bone graft (ICBG) for spine fusion. Starting from 1990, a 25-years-old woman underwent two subsequent surgical treatments for non-Hodgkin lymphoma vertebral localizations. In the second surgery, arthrodesis was obtained with autograft through right posterior iliac crest osteotomy. During the chemotherapy treatment following the surgery, the patient suffered from infection at posterior iliac crest scar, the site of previous graft, caused by methicillin-resistant Staphylococcus aureus. She was subjected to surgical debridement and specific antibiotic treatment with local healing and phlogosis index reduction. Chemotherapy protocol was concluded and the patient healed with definitive lymphoma remission. After 22 years the patient had a relapse of donor site infection, requiring a new antibiotic therapy and a new surgical debridement. The relapsed infection at donor site lasted for a long period, more than one year, despite of specific care. It finally healed after another accurate surgical debridement and postoperative antibiotic therapy. This case report underlines the possible consequences on the patient's quality of life of a long-term disease affecting the iliac crest bone graft donor site. Literature concerning alternatives to autograft for spine fusion is also reviewed.

The purpose of this prospective cohort study was to evaluate patient-based outcomes and complications following excision of mucous cysts, joint debridement, and closure with one of three types of local flaps. From 2000-2011, 35 consecutive patients with 37 digital mucous cysts were treated surgically. The surgical procedure included excision of the cyst together with the attenuated skin, joint debridement on the affected side including capsulectomy, and removal of osteophytes. Depending on the size and location of the cyst, the skin defect was covered by a transposition flap (31 cysts), an advancement flap (two cysts), or a rotation flap (four cysts). At an average follow-up time of 4 years, 4 months, there was no wound infection, flap necrosis, or joint stiffness. Preoperative nail ridging resolved in seven of nine fingers, and no nail deformities developed after surgery. One cyst, treated with a transposition flap, recurred 10 months after surgery. The average satisfaction score for the affected finger significantly improved from 4.3 to 6.8, and the average pain score decreased from 4.7 to 2.3. This treatment protocol provides reliable results. Patients were satisfied with the reduction of associated pain and the postoperative appearance of the treated finger, and postoperative complications were minimal.

To examine the efficacy of a novel supplementary irrigant agitating brush (Finisher GF Brush, MedicNRG, Kibbutz Afikim, Israel) on the debridement of root canals prepared with a novel stainless steel rotary instrumentation system (Gentlefile; MedicNRG), or nickel titanium rotary instruments in oval root canals. Mandibular premolars (n = 72) were selected and divided randomly into three experimental groups (n = 24) after microCT scanning: group 1, canal preparation to rotary NiTi size 20, .04 taper (R20); group 2, rotary NiTi to size 25, .04 taper (R25) and group 3, Gentlefile size 23, .04 taper (GF). Specimens were subdivided into two subgroups: subgroup A, syringe-and-needle irrigation (SNI); subgroup B, Finisher GF Brush (GB). Ten untreated canals served as controls. Specimens were processed for histological evaluation, and the remaining pulp tissue (RPT) was measured. Data were analysed using Mann-Whitney and Kruskal-Wallis tests (P = 0.05). All experimental groups had significantly less RPT than the control (P < 0.05). Group 3B (GF-GB) had significantly less RPT than groups 1B (R20-GB) and 2B (R25-GF; P < 0.05). When irrigated with SNI, there was no significant difference in the RPT between the three groups (P > 0.05). When instrumented with R20, there was no significant difference between SNI and GF (P < 0.05) whilst GB had significantly less RPT than SNI for R25 (P < 0.05). Supplementary irrigant agitation with the Finisher GF Brush improved the debridement of canals prepared with Gentlefile and size 25, .04 taper rotary NiTi. Root canal debridement did not significantly differ between the instruments when syringe irrigation was used. © 2018 International Endodontic Journal. Published by John Wiley & Sons Ltd.

Shock frequently complicates necrotizing fasciitis (NF) caused by group A Streptococcus (GAS) or Staphylococcus aureus. Intravenous immunoglobulin (IVIG) is sometimes administered for presumptive toxic shock syndrome (TSS), but its frequency of use and efficacy are unclear. Adult patients with NF and vasopressor-dependent shock undergoing surgical debridement from 2010 to 2014 were identified at 130 US hospitals. IVIG cases were propensity-matched and risk-adjusted. The primary outcome was in-hospital mortality and the secondary outcome was median length of stay (LOS). Of 4127 cases of debrided NF with shock at 121 centers, only 164 patients (4%) at 61 centers received IVIG. IVIG subjects were younger with lower comorbidity indices, but higher illness severity. Clindamycin and vasopressor intensity were higher among IVIG cases, as was coding for TSS and GAS. In-hospital mortality did not differ between matched IVIG and non-IVIG groups (crude mortality, 27.3% vs 23.6%; adjusted odds ratio, 1.00 [95% confidence interval, .55-1.83]; P = .99). Early IVIG (≤2 days) did not alter this effect (P = .99). Among patients coded for TSS, GAS, and/or S. aureus, IVIG use was still unusual (59/868 [6.8%]) and lacked benefit (P = .63). Median LOS was similar between IVIG and non-IVIG groups (26 [13-49] vs 26 [11-43]; P = .84). Positive predictive values for identifying true NF and debridement among IVIG cases using our algorithms were 97% and 89%, respectively, based on records review at 4 hospitals. Adjunctive IVIG was administered infrequently in NF with shock and had no apparent impact on mortality or hospital LOS beyond that achieved with debridement and antibiotics.

Williams, R J; Fries, C A; Midwinter, M; Lambert, A W

2013-09-01

There is little documented advice on the management of scrotal trauma sustained in combat. This paper reviews this injury, its present surgical management and makes recommendations for the future. All UK forces sustaining scrotal injuries between 2003 and 2009, in Iraq and Afghanistan, initially treated at a Role 2 (enhanced) or Role 3 deployed military surgical facility were identified from the Joint Theatre Trauma Registry. The cause and extent of the injury, in addition to the surgical management, are reported. Twenty-seven patients sustained trauma to their scrotum; improvised explosive device (IED) (n=21), mine (n=3), rocket propeller grenade (RPG) (n=2), mortar round (n=1). Of those injured by an IED, eleven had traumatic orchidectomies, of which 4 were bilateral, one received fragmentation wounds to the scrotum with a testicular injury that was salvaged and there were six scrotal fragmentation wounds not associated with a testicular injury. Scrotal exploration was performed with testicular salvage in all cases involving mortar, RPG or mines. For all aetiologies the scrotum was debrided with primary closure over a drain (n=7), debridement and subsequent delayed primary closure (DPC) (n=4) or healing by secondary intension (n=6). Skin grafts were applied in two cases of traumatic bilateral orchidectomy. To date there have been two cases of delayed orchidectomy; chronic pain and delayed presentation of a disrupted testis. All reported patients survived. The established principles of debridement should be the mainstay of treatment. Testicular ischaemia, a consequence of cord transaction, necessitates orchidectomy. Salvage of the disrupted testis, with debridement and closure of the tunica rather than orchidectomy, should be performed whenever possible, particularly when there is significant bilateral testicular injury. Scrotal wounds can be treated by closure over a drain, DPC or healing by secondary intention. Copyright © 2013 Elsevier Ltd. All rights reserved.

Focal lesions to the articular cartilage in the knee might have demolishing consequences to the knee. There exists a wide range of possible surgical procedures targeting these injuries, however no significant differences have been found between these procedures. This may support that the improvement is a result of rehabilitation, and not the surgery itself. Arthroscopic microfracture (MF) treatment has gained popularity, and has become the treatment of choice in patients with knee cartilage defects globally. In this study we want to increase knowledge, both clinical and economic, about arthroscopic microfracture (AF) compared to arthroscopic debridement (AD) and physical rehabilitation both in the short run, and in the long run. To compare arthroscopic microfracture with arthroscopic debridement and physiotherapy for the treatment of focal cartilage lesions in the knee, a long-term, double-blinded, randomized controlled multicenter trial will be conducted. A total of 114 men and non-pregnant women with a symptomatic focal full thickness cartilage lesion in the knee less than 2 cm2 will be included in the study. The two treatment allocations will receive identical rehabilitation, which is made up of 3 phases: accommodation, rehabilitation and return to activity. Follow up is 24 months, where all will be invited to participate in late follow ups after 5 and 10 years. The Knee Injury and Osteoarthritis Outcome Score (KOOS) knee-related quality of life (QoL) subscore is the primary endpoint. Clinical parameters, questionnaires and radiologic modalities (Magnetic Resonance Imaging (MRI) and x-ray) will be used as secondary endpoints. This is an ongoing multicenter study with a high level of evidence to compare arthroscopic microfracture with arthroscopic debridement and physiotherapy for the treatment of isolated symptomatic full thickness cartilage lesions in the knee joint.

Recent advances in imaging modalities have enabled three-dimensional preoperative simulation. A four-dimensional preoperative simulation system would be useful for debridement arthroplasty of primary degenerative elbow osteoarthritis because it would be able to detect the impingement lesions. We developed a four-dimensional simulation system by adding the anatomical axis to the three-dimensional computed tomography scan data of the affected arm in one position. Eleven patients with primary degenerative elbow osteoarthritis were included. A "two rings" method was used to calculate the flexion-extension axis of the elbow by converting the surface of the trochlea and capitellum into two rings. A four-dimensional simulation movie was created and showed the optimal range of motion and the impingement area requiring excision. To evaluate the reliability of the flexion-extension axis, interobserver and intraobserver reliabilities regarding the assessment of bony overlap volumes were calculated twice for each patient by two authors. Patients were treated by open or arthroscopic debridement arthroplasties. Pre- and postoperative examinations included elbow range of motion measurement, and completion of the patient-rated questionnaire Hand20, Japanese Orthopaedic Association-Japan Elbow Society Elbow Function Score, and the Mayo Elbow Performance Score. Measurement of the bony overlap volume showed an intraobserver intraclass correlation coefficient of 0.93 and 0.90, and an interobserver intraclass correlation coefficient of 0.94. The mean elbow flexion-extension arc significantly improved from 101° to 125°. The mean Hand20 score significantly improved from 52 to 22. The mean Japanese Orthopaedic Association-Japan Elbow Society Elbow Function Score significantly improved from 67 to 88. The mean Mayo Elbow Performance Score significantly improved from 71 to 91 at the final follow-up evaluation. We showed that four-dimensional, preoperative simulation can be generated by adding the rotation axis to the one-position, three-dimensional computed tomography image of the affected arm. This method is feasible for elbow debridement arthroplasty.

Optimal management of poststernotomy mediastinitis is controversial. Negative pressure wound treatment improves wound environment and sternal stability with low surgical invasiveness. Our protocol was based on negative pressure followed by delayed surgical closure. The aim of this study was to provide the results at early follow-up and to identify the risk factors for adverse outcome. In 5400 cardiac procedures, 44 consecutive patients with mediastinitis were enrolled in the study. Mediastinitis treatment was based on urgent debridement and negative pressure as the first-line approach. After wound sterilization, chest closure was achieved by elective pectoralis muscle advancement flap. Each patient's hospital data were collected prospectively. Variables included patient demographics and clinical and biological data. Acute Physiology and Chronic Health Evaluation (APACHE) II score was calculated at the time of diagnosis and 48 hours after debridement. Focus outcome measures were mediastinitis-related death and need for reintervention after pectoralis muscle closure. El Oakley type I and type IIIA mediastinitis were the most frequent types (63.6%). Methicillin-resistant Staphylococcus aureus was present in 25 patients (56.8%). Mean APACHE II score was 19.4±4 at the time of diagnosis, and 30 patients (68.2%) required intensive care unit transfer before surgical debridement. APACHE II score improved 48 hours after wound debridement and negative pressure application (mean value, 19.4±4 vs 7.2±2; P=.005) independently of any other variables included in the study. One patient in septic shock at the time of diagnosis died (2.2%). Negative pressure promotes a significant improvement in clinical status according to APACHE II score and allows a successful elective surgical closure.

This study was undertaken to prospectively analyse, at a mean five-year follow-up, the clinical, functional, and radiographic outcomes in patients who developed postoperative acute septic knee arthritis following anterior cruciate ligament (ACL) reconstruction using hamstring autograft. We also assessed the effect of multiple arthroscopic debridement and graft retention on the functional outcomes in comparison with the matched control group. From a consecutive case series of 2,560 ACL-injured patients who were treated with arthroscopic ACL reconstruction, we report on 24 cases with postoperative septic knee arthritis. These patients were individually matched for age, sex, comorbidity, body mass index (BMI) and preinjury Tegner activity scale in a ratio of 1/1. Clinical, laboratory, synovial fluid analysis and culture were performed. Arthroscopic debridement and graft retention was done for all cases, in addition to antibiotic therapy i.v.. A detailed physical examination, KT1000 laxity testing, Lysholm knee score, Tegner activity level scale, International Knee Documentation Committee (IKDC), and Knee Injury and Osteoarthritis Outcome Score (KOOS) were completed. In all cases, treatment of infection was successful after a median of three (range one to six) repeated arthroscopic graft debridement and retention, in addition to antibiotic therapy i.v.. At an average of five years follow-up, two patients had over five millimetres manual maximum side-to-side difference in laxity. There were no significant differences between groups regarding Lysholm score, IKDC and KOOS. Median final Tegner activity score was 5.5 versus 7 in the control group (p = 0.004). Complications included graft rupture in three patients, loss of range of motion in five, Sudeck's atrophy in one and moderate joint narrowing in two. There were no recurrences of septic arthritis or bone infection. Graft retention seems not only possible but appropriate in view of the experience presented in this article for postoperative septic knee arthritis using hamstring autograft. A potential residual complication is arthrofibrosis, which deserves maximum attention.

Retrospective analysis of the clinical efficacy and feasibility of patients with thoracolumbar spinal tuberculosis with psoas abscesses treated by one-stage posterior transforaminal lumbar debridement, interbody fusion, posterior instrumentation, and postural drainage. A total of 18 patients with thoracolumbar tuberculosis (TB), between February 2007 and February 2011, underwent one-stage posterior transforaminal lumbar debridement, interbody fusion, posterior instrumentation, and postural drainage. And the clinical efficacy was evaluated based on surgery duration time, the blood loss, the postural drainage of time, neurological status that was recorded by American Spinal Injury Association (ASIA) Impairment Scale, the fate of bone graft fusion, kyphosis angle, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP), which were collected at certain time. The average follow-up period was 34 months (range 18-48 months). 18 patients suffered from seriously neurological deficits pre-operatively, of which 16 patients returned to normal at final follow-up. The surgery duration time was 197 ± 37.9 min, and the blood loss was 815 ± 348.5 ml. The postural drainage of time was 7.2 ± 2.7 days. The psoas abscesses disappeared in all cases, within the time range of 6-9 months (mean 7.4 ± 1.2 months). All patients of the grafted bones were thoroughly fused, with a fusion time ranging from 4 to 12 months (mean 7.8 months). Kyphosis angle was 44.32 ± 7.26° on average pre-operative and returned to 11.72 ± 2.85° at 6 weeks after operation; kyphosis angle was 13.10 ± 2.39° at final follow-up. The values of ESR and CRP were significant declined at 6 weeks post-operative, and returned to normal levels at final follow-up. With standardized anti-TB chemotherapy, thoracolumbar spinal tuberculosis with psoas abscesses could be effectively treated by one-stage posterior transforaminal lumbar debridement, interbody fusion, posterior instrumentation, and postural drainage.

We aim to evaluate the epidemiology and outcome of gram-negative prosthetic joint infection (GN-PJI) treated with debridement, antibiotics and implant retention (DAIR), identify factors predictive of failure, and determine the impact of ciprofloxacin use on prognosis. We performed a retrospective, multicentre, observational study of GN-PJI diagnosed from 2003 through to 2010 in 16 Spanish hospitals. We define failure as persistence or reappearance of the inflammatory joint signs during follow-up, leading to unplanned surgery or repeat debridement>30 days from the index surgery related death, or suppressive antimicrobial therapy. Parameters predicting failure were analysed with a Cox regression model. A total of 242 patients (33% men; median age 76 years, interquartile range (IQR) 68-81) with 242 episodes of GN-PJI were studied. The implants included 150 (62%) hip, 85 (35%) knee, five (2%) shoulder and two (1%) elbow prostheses. There were 189 (78%) acute infections. Causative microorganisms were Enterobacteriaceae in 78%, Pseudomonas spp. in 20%, and other gram-negative bacilli in 2%. Overall, 19% of isolates were ciprofloxacin resistant. DAIR was used in 174 (72%) cases, with an overall success rate of 68%, which increased to 79% after a median of 25 months' follow-up in ciprofloxacin-susceptible GN-PJIs treated with ciprofloxacin. Ciprofloxacin treatment exhibited an independent protective effect (adjusted hazard ratio (aHR) 0.23; 95% CI, 0.13-0.40; p<0.001), whereas chronic renal impairment predicted failure (aHR, 2.56; 95% CI, 1.14-5.77; p 0.0232). Our results confirm a 79% success rate in ciprofloxacin-susceptible GN-PJI treated with debridement, ciprofloxacin and implant retention. New therapeutic strategies are needed for ciprofloxacin-resistant PJI. © 2014 The Authors Clinical Microbiology and Infection © 2014 European Society of Clinical Microbiology and Infectious Diseases.

Aspergillus osteomyelitis of the vertebral body and disc space is rare. This report discusses a case that occurred in an immunosuppressed 29-year-old man and reviews the pertinent medical literature. To review the management and treatment of Aspergillus osteomyelitis of the vertebral body and disc space. The patient presented with acute neurologic compromise resulting from L5-S1 discitis and a large epidural soft tissue component secondary to the Aspergillus infection. The patient underwent aggressive surgical debridement along with treatment with amphotericin B and had a complete clinical recovery. The authors recommend a combined medical-surgical approach in most cases of vertebral Aspergillus osteomyelitis. Early surgery with vigorous surgical debridement along with antifungal treatment seems to yield a good outcome.

Vulvar necrotizing fasciitis is a surgical emergency with a high rate of morbidity and mortality. Our case series adds seven patients to the literature and presents the first group that is predominantly of Pacific-Islander origin. This study not only confirms traditional risk factors such as diabetes mellitus, obesity and hypertension but investigates ethnicity and socioeconomic status as risk factors. Also presented is a case of recurrent necrotizing fasciitis initially involving the vulva, then the back. In any patient for which there is suspicion of vulvar necrotizing fasciitis, surgical diagnosis remains the gold standard and facilitates rapid debridement of all necrotic tissues. Aggressive surgical debridement with broad spectrum antibiotic coverage is required to minimize mortality. PMID:20222491

Periocular necrotizing fasciitis in an infant.

Proia, Alan D

Periocular necrotizing fasciitis developed in a 12-month-old boy with swelling of both eyes and redness and a discharge from the left eye approximately 36 hours after blunt trauma. Computed tomography revealed preseptal and soft-tissue edema on the left side, but no signs of orbital involvement, orbital fractures, or drainable abscess in the anterior left lower eyelid. The inflammatory signs worsened over the next day, and there was purulent discharge from the left lower eyelid and an abscess and necrosis of the lower eyelid skin. He did well following surgical debridement and treatment with intravenous antibiotics. His course highlights the difficulty in diagnosing necrotizing fasciitis and the necessity for prompt surgical debridement and empirical broad-spectrum antibiotic therapy.

Pancreatic and peripancreatic fluid collections may develop after severe acute pancreatitis. Organized fluid collections such as pancreatic pseudocyst and walled-off pancreatic necrosis (WOPN) that mature over time may require intervention to treat obstructive or constitutional symptoms related to the size and location of the collection as well as possible infection. Endoscopic, open surgical and minimally invasive techniques are described to treat post-inflammatory pancreatic fluid collections. Surgical intervention may be required to treat collections containing necrotic pancreatic parenchyma or in locations not immediately apposed to the stomach or duodenum. Comprising a blend of the surgical approach and the clinical benefits of minimally invasive surgery, the robot-assisted technique of pancreatic cystgastrostomy with pancreatic debridement is described.

Acute postoperative and acute, late hematogenous prosthetic joint infections have been treated with 1-stage irrigation and debridement with polyethylene exchange. Success rates, however, are highly variable. Reported studies demonstrate that detergents are effective at decreasing bacterial colony counts on orthopedic implants. Our hypothesis is that the combination of a detergent and an antiseptic would be more effective than using a detergent alone to decrease colony counts from a methicillin-resistant Staphylococcus aureus biofilm-coated titanium alloy disk simulating an orthopedic implant. In our study of various agents tested, chlorhexidine gluconate scrub (antiseptic and detergent) was the most effective at decreasing bacterial colony counts both prereincubation and postreincubation of the disks; pulse lavage and scrubbing were not more effective than pulse lavage alone.

The management of modern traumatic war wounds remains a significant challenge for clinicians. This is a reflection of the extensive osseous and soft-tissue damage caused by blasts and high-energy projectiles. The ensuing inflammatory response ultimately dictates the pace of wound healing and tissue regeneration. Consequently, the eventual timing of wound closure or definitive coverage is often subjectively based. Some wounds require an extended period of time to close or fail to remain closed, despite the use and application of novel wound-specific treatment modalities. Aside from impaired wound healing, additional wound complications include wound infection, biofilm formation, and heterotopic ossification (the pathological mineralization of soft tissues). An understanding of the molecular environment of acute wounds throughout the debridement process can provide valuable insight into the mechanisms associated with the eventual wound outcome. The analysis of Raman spectra of ex vivo wound biopsy tissue obtained from serial traumatic wound debridements reveals a decreased 1665 cm-1/1445 cm-1 band area ratio in impaired healing wounds, indicative of an impaired remodeling process, in addition to a decreased 1240 cm-1/1270cm-1. The examination of debrided tissue exhibits mineralization during the early development of heterotopic ossification. Finally, preliminary results suggest that Fourier transform infrared (FT-IR) images of wound effluent may be able to provide early microbiological information about the wound.

Charcot arthropathy of the peritalar complex carries a high risk of amputation if not properly managed. Our aim is to assess the functional outcome of severe Charcot arthropathy of the peritalar complex following enblock resection of the ulcer, massive debridement and stabilizing all the elements of the peritalar complex. We prospectively studied 38 feet in 35 patients with peritalar complex Charcot arthropathy. All Feet underwent intense debridement and fusion using a combination of (Ilizarov) external fixation, and (plate and locked nail) internal fixation. Thirty two feet were graded as Eichenholtz 2, and six feet were graded as Eichenholtz 3. The mean follow up was 35.9months. The mean AOFAS score was significantly elevated from 25.4±9.1 preoperatively to 67.6±5.7 at the most recent follow-up (p<0.001). Complete bony fusion was achieved in 28 feet. Unsound bony fusion occurred in 8 feet. Two feet required below knee amputation. Peritalar complex Charcot arthropathy is not uncommon variety. Such cases carry high risk of complications and amputation is not excluded. The proper timing of surgery is crucial. Massive debridement and rigid fixation with strict follow up is mandatory to achieve the ultimate goal of obtaining a plantigrade, stable, mechanically sound, painless and infection free pedal construct.

2013-01-01

Implant related sepsis is a relatively unusual complication of intra-medullary nail fixation of long bone fractures. Depending on the extent of infection, timing of diagnosis and progress of fracture union, different treatment strategies have been developed. The aim of this review article is to collect and analyze the existing evidence about the incidence and management of infection following IM nailing of long bone fractures and to recommend treatment algorithms that could be valuable in everyday clinical practice. After searching the P u b M e d /Medline databases, 1270 articles were found related to the topic during the last 20 years. The final review included 28 articles that fulfilled the inclusion criteria. Only a few prospective studies exist to report on the management of infection following IM nailing of long-bone fractures. In general, stage I (early) infections only require antibiotic administration with/without debridement. Stage II (delayed) infections can be successfully treated with debridement, IM reaming, antibiotic nails, and administration of antibiotics. Infected non-unions are best treated with exchange nailing, antibiotic administration and when infection has been eradicated with graft implantation if it is needed. Debridement, exchange nailing and systemic administration of antibiotics is the best indication for stage III (late) infections, while stage III infected non-unions can successfully be treated with nail removal and Ilizarov frame, especially when large bone defects exist.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique that has been shown to provide central vascular control to support proximal aortic pressure and minimize hemorrhage in a wide variety of clinic settings, however the role of REBOA for emergency general surgery is less defined. This is a report of a 44 year old man who experienced hemorrhagic shock during video-assisted retroperitoneal debridement (VARD) for necrotizing pancreatitis where REBOA was used to prevent ongoing hemorrhage and death. This is the first documented report REBOA being used during pancreatic debridement in the literature and one of the first times it has been used in emergency general surgery. The use of REBOA is an option for those in hemorrhagic shock whom conventional aortic cross-clamping or supra-celiac aortic exposure is either not possible or exceedingly dangerous. REBOA allows for adequate resuscitation and can be used as a bridge to definitive therapy in a range of surgical subspecialties with minimal morbidity and complications. The risks associated with insertion of wires, sheaths, and catheters into the arterial system, as well as the risk of visceral and spinal cord ischemia due to aortic occlusion mandate that the use of this technique be utilized in only appropriate clinical scenarios.

To evaluate the clinical efficacy of the one-stage posterior approach in treating consecutive multiple-segment thoracic tuberculosis with kyphosis. A retrospective study was performed. The data of 22 patients with consecutive multi-level thoracic tuberculosis and kyphosis who underwent the one-stage posterior approach of debridement, bone grafting, drainage and pedicle screws fixation were collected. The kyphotic angle was 61.6°±3.1° pre-operatively. The neurologic status based on American Spinal Injury Association (ASIA) scoring was A in 5 cases, B in 4 cases, C in 9 cases, D in 3 cases and E in 1 case. The average follow-up period was 43.4±5.0 months. The kyphotic angle was 19.8°±0.7° after operation (p < 0.01), and 21.9°±1.2° at the last visit (p < 0.01). No neurological deterioration was observed in any patients after surgery. A significant difference in ASIA score was detected when the state before the operation and at the last visit was compared (p < 0.01). There was no recurrent paravertebral abscess of thoracic tuberculosis in any of these cases. The one-stage posterior approach of debridement and drainage is a feasible surgical option for consecutive multisegment thoracic tuberculosis with kyphosis. It can achieve debridement, decompression, and stabilization simultaneously.

The aim of this study was to retrospectively measure the outcomes of foot-sparing surgery at one year follow-up for patients with diabetic foot ulcers (DFUs). We assessed wound healing and the need for further surgery in relation to the variables that influence healing. Data were retrospectively collected by reviewing the electronic files of patients attending the Wound Expert Clinic (WEC). Outcomes of surgical debridement, toe, ray and transmetatarsal amputations were assessed. A total of 129 cases in 121 patients were identified for inclusion. The results demonstrated that complete wound healing was reached in 52% (61/117) of the patients within 12 months. The need for additional surgery or for major amputation was 56% (n=72/129) and 30% (n=39/129) respectively. The need for an additional procedure was particularly high after surgical debridement (75%, 33/44) and transmetatarsal amputation (64%, 7/11). Risk factors for non-healing or for a major amputation were: infection (p=0.01), ischaemia (p=0.01), a history of peripheral arterial occlusive disease (p<0.01) and smoking (p=0.01). Additional findings were that not all patients underwent vascular assessment and in half of the patients there was a delay in undergoing revascularisation. The results of the study reveal some areas for improvement including timely revascularisation and performance of multiple debridement procedures if needed in order to save a limb.

To compare patients' perception of discomfort, vibration and noise levels between piezoelectric and the magnetostrictive ultrasonic units during periodontal debridement. Periodontal debridement was performed on 75 subjects using a split-mouth design. Two quadrants on the same side were instrumented with a piezoelectric ultrasonic device (EMS Swiss Mini Master® Piezon) and the remaining 2 quadrants were instrumented with a magnetostrictive ultrasonic device (Dentsply Cavitron® SPS™). Subjects marked between 0 and 100 along a visual analog scale (VAS) for each of the 3 variables immediately after treatment of each half of the dentition. Scores of the VAS were compared using a nonparametric test for paired data, the Wilcoxon Signed-Rank test. The level of significance was set at p<0.05. Descriptive statistics included the median and the first and third quartiles as a measure of variation. Mean scores for patient discomfort and vibration were greater for the magnetostrictive device at p=0.007 and p=0.032, respectively. The scores for noise level between the 2 ultrasonic types were almost equal. The results show that, on average, patients in this study prefer instrumentation with the piezoelectric as it relates to awareness of associated discomfort and vibration. The results of this study may assist the clinician in the decision over which ultrasonic device may prove more beneficial in decreasing patient discomfort and increasing patient compliance.

Necrotizing Fasciitis of the Abdominal Wall Caused by Serratia Marcescens

In this article, we present the first case of necrotizing fasciitis affecting the abdominal wall caused by Serratia marcescens and share results of a focused review of S. marcescens induced necrotizing fasciitis. Our patient underwent aorto-femoral bypass grafting for advanced peripheral vascular disease and presented 3 weeks postoperatively with pain, erythema and discharge from the incision site in the left lower abdominal wall and underwent multiple debridement of the affected area. Pathology of debrided tissue indicated extensive necrosis involving the adipose tissue, fascia and skeletal muscle. Wound cultures were positive for Serratia marcescens. She was successfully treated with antibiotics and multiple surgical debridements. Since necrotizing fasciitis is a medical and surgical emergency, it is critical to examine infectivity trends, clinical characteristics in its causative spectrum. Using PubMed we found 17 published cases of necrotizing fasciitis caused by Serratia marcescens, and then analyzed patterns among those cases. Serratia marcescens is prominent in the community and hospital settings, and information on infection presentations, risk factors, characteristics, treatment, course, and complications as provided through this study can help identify cases earlier and mitigate poor outcomes. Patients with positive blood cultures and those patients where surgical intervention was not provided or delayed had a higher mortality. Surgical intervention is a definite way to establish the diagnosis of necrotizing infection and differentiate it from other entities. PMID:26294949

Prosthetic joint infection is an unfortunate though well-recognized complication of total joint arthroplasty. An iliacus and/or iliopsoas muscle abscess is a rarely documented presentation of hip prosthetic joint infection. It is thought an unrecognized retroperitoneal nidus of infection can be a source of continual seeding of the prosthetic hip joint, prolonging attempts to eradicate infection despite aggressive debridement and explant attempts. The current study presents five cases demonstrating this clinical scenario, and discusses various treatment challenges. In each case we report the patient's clinical history, pertinent imaging, management and outcome. Diagnosis of the iliacus muscle abscess was made using computed tomography imaging. In brief, the mean number of total drainage procedures (open and percutaneous) per patient was 4.2, and outcomes consisted of one patient with a hip girdlestone, two patients with delayed revisions, and two patients with retained prosthesis. All patients ended with functional pain and on oral antibiotic suppression with an average follow up of 18 months. This article highlights an iliacus muscle abscess as an unrecognized source of infection to a prosthetic hip. It demonstrates resilience to standard treatment protocols for prosthetic hip infection, and is associated with poor patient outcomes. Aggressive surgical debridement appears to remain critical to treatment success, and early retroperitoneal debridement of the abscess should be considered.

Prolonged Allograft Survival in a Patient With Chronic Immunosuppression: A Case Report and Systematic Review.

PubMed

Vyas, Krishna S; Burns, Chase; Ryan, Dylan T; Wong, Lesley

2017-06-01

A 41-year-old man with past medical history of kidney-liver transplantation requiring chronic immunosuppression presented 2 years posttransplant with a necrotizing soft tissue infection of his right thigh. Serial debridement to remove necrotic tissue was performed, and a Matrix HD Allograft Fenestrated (RTI Surgical, Alachua, FL) was applied. At 5-months post grafting, the patient demonstrated fully vascularized and intact skin. Under normal circumstances, a cadaveric allograft sloughs over several weeks and is not usually considered a permanent solution for wound closure. A systematic review of transplant patients on chronic immunosuppression with skin allografts demonstrates the potential for the indefinite survival of an allograft. Necrotizing soft tissue infections can definitively be treated using serial debridement and allograft transplantation in the chronically immunosuppressed.

Endoscopic Debridement for Treatment of Chronic Plantar Fasciitis: An Innovative Surgical Technique.

PubMed

Cottom, James M; Maker, Jared M

Plantar fasciitis is one the most common pathologies seen by foot and ankle surgeons. When nonoperative therapy fails, surgical intervention is warranted. Various surgical procedures are available for the treatment of recalcitrant plantar fasciitis. The most common surgical management typically consists of open versus endoscopic plantar fascia release. The documented comorbidities associated with the release of the plantar fascia include lateral column overload and metatarsalgia. We present a new technique for this painful condition that is minimally invasive, allows visualization of the plantar fascia, and maintains the integrity of this fascia. Our hypothesis was that the use of endoscopic debridement of the plantar fascia would provide a minimally invasive technique with acceptable patient outcomes.

To evaluate the repairing methods of bulky tissue defect of forearm with flaps. Twenty-one burned patients with wounds in the forearm were enrolled in this study. The injury causes were high-voltage electricity, hot press or crush injury. After local debridement, the forearm defects were repaired with pedicled complex flaps, latissimus dorsi musculocutaneous island flaps or large thoraco-abdominal flaps immediately. All the flaps survived very well with satisfactory results except for 1 patient in whom local ischemic necrosis and sub-flap infection at the distal end of the flap occurred. Early debridement followed by skin flaps with pedicles or musculocutaneous flaps transfer could be simple, safe and reliable treatment strategies in the management of bulky tissue defects of the forearm due to burn, electric injury, or other devastating injuries.

To evaluate the clinical outcomes of anterior and posterior instrumentation with different debridement and graft fusion methods for multi-level contiguous thoracic spinal tuberculosis. We retrospectively evaluated 81 patients with multi-level contiguous thoracic spinal tuberculosis who underwent anterior or posterior instrumentation combined with different methods of debridement, decompression, and graft fusion from January 2002 to December 2012. All patients were divided into an anterior instrumentation group and a posterior instrumentation group. In the anterior instrumentation group, there were 39 patients who underwent transthoracic debridement. In the posterior instrumentation group, there were 34 patients who underwent trans-costotransverse decompression and strut grafting with posterior instrumentation, and another 8 patients underwent combined anterior debridement and strut grafting with posterior instrumentation in a single-stage or two-stage procedure. The kyphotic angles were calculated from lateral spinal X-rays using the modified Konstam method. The symptoms and signs of tuberculosis, fusion level, fusion time of the bone graft, average kyphosis angle, average correction, average loss of correction, and clinical complications were recorded. The average follow-up period was 37 months (range, 17-72 months). The cohort consisted of 47 males and 34 females with an average age of 38 years. The mean durations of the operations were 3.5 ± 0.4 h in the anterior group and 4.0 ± 0.3 h in the posterior group ( P < 0.05). The mean blood loss volumes during surgery were 450 ± 42 and 560 ± 51 mL for the anterior group and the posterior group, respectively ( P < 0.01). The kyphotic deformities were corrected from 32.1° ± 10.3° to 10.2° ± 2.1° in the anterior group and from 33.8° ± 11.7° to 12.6° ± 2.7° in the posterior group ( P < 0.01). The neurologic statuses of the 23 patients with preoperative neurologic deficits improved in each group. Fusion was confirmed radiographically at 5.4 ± 1.2 months (range, 4-12 months) in the anterior group and 5.6 ± 1.4 months (range, 4-13 months) in the posterior group ( P > 0.05). Postoperative relapses were noted in 1 and 3 patients in the anterior and the posterior group, respectively. Posterior instrumentation was more effective than anterior instrumentation in the correction of kyphosis and the maintenance of the correction. However, postoperative sinus formation was more frequent in patients who underwent a single-stage posterior procedure. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

Return to Preinjury Levels of Participation After Superior Labral Repair in Overhead Athletes: A Systematic Review

Sciascia, Aaron; Myers, Natalie; Kibler, W. Ben; Uhl, Timothy L.

2015-01-01

Context Athletes often preoperatively weigh the risks and benefits of electing to undergo an orthopaedic procedure to repair damaged tissue. A common concern for athletes is being able to return to their maximum levels of competition after shoulder surgery, whereas clinicians struggle with the ability to provide a consistent prognosis of successful return to participation after surgery. The variation in study details and rates of return in the existing literature have not supplied clinicians with enough evidence to give overhead athletes adequate information regarding successful return to participation when deciding to undergo shoulder surgery. Objective To investigate the odds of overhead athletes returning to preinjury levels of participation after arthroscopic superior labral repair. Data Sources The CINAHL, MEDLINE, and SPORTDiscus databases from 1972 to 2013. Study Selection The criteria for article selection were (1) The study was written in English. (2) The study reported surgical repair of an isolated superior labral injury or a superior labral injury with soft tissue debridement. (3) The study involved overhead athletes equal to or less than 40 years of age. (4) The study assessed return to the preinjury level of participation. Data Extraction We critically reviewed articles for quality and bias and calculated and compared odds ratios for return to full participation for dichotomous populations or surgical procedures. Data Synthesis Of 215 identified articles, 11 were retained: 5 articles about isolated superior labral repair and 6 articles about labral repair with soft tissue debridement. The quality range was 11 to 17 (42% to 70%) of a possible 24 points. Odds ratios could be generated for 8 of 11 studies. Nonbaseball, nonoverhead, and nonthrowing athletes had a 2.3 to 5.8 times greater chance of full return to participation than overhead/throwing athletes after isolated superior labral repair. Similarly, nonoverhead athletes had 1.5 to 3.5 times greater odds for full return than overhead athletes after labral repair with soft tissue debridement. In 1 study, researchers compared surgical procedures and found that overhead athletes who underwent isolated superior labral repair were 28 times more likely to return to full participation than those who underwent concurrent labral repair and soft tissue debridement (P < .05). Conclusions The rate of return to participation after shoulder surgery within the literature is inconsistent. Odds of returning to preinjury levels of participation after arthroscopic superior labral repair with or without soft tissue debridement are consistently lower in overhead/throwing athletes than in nonoverhead/nonthrowing athletes. The variable rates of return within each group could be due to multiple confounding variables not consistently accounted for in the articles. PMID:25946167

Recurrent respiratory papillomatosis: a longitudinal study comparing severity associated with human papilloma viral types 6 and 11 and other risk factors in a large pediatric population.

A database was developed for prospective, longitudinal study of recurrent respiratory papillomatosis (RRP) in a large population of pediatric patients. Data recorded for each patient included epidemiological factors, human papilloma virus (HPV) type, clinical course, staged severity of disease at each surgical intervention, and frequency of surgical intervention. The study hypothesizes that patients with HPV type 11 (HPV-11) and patients younger than 3 years of age at diagnosis are at risk for more aggressive and extensive disease. The 10-year prospective epidemiological study used disease staging for each patient with an original scoring system. Severity scores were updated at each surgical procedure. Parents of children with RRP referred to the authors' hospital completed a detailed epidemiological questionnaire at the initial visit or at the first return visit after the study began. At the first endoscopic debridement after study enrollment, tissue was obtained and submitted for HPV typing using polymerase chain reaction techniques and in situ hybridization. Staging of disease severity was performed in real time at each endoscopic procedure using an RRP scoring system developed by one of the authors (B.J.W.). The frequency of endoscopic operative debridement was recorded for each patient. Information in the database was analyzed to identify statistically significant relationships between extent of disease and/or HPV type, patient age at diagnosis, and selected epidemiological factors. The study may represent the first longitudinal prospective analysis of a large pediatric RRP population. Fifty-eight of the 73 patients in the study underwent HPV typing. Patients infected with HPV-11 were significantly more likely to have higher severity scores, require more frequent surgical intervention, and require adjuvant therapy to control disease progression. In addition, patients with HPV-11 RRP were significantly more likely to develop tracheal disease, to require tracheotomy, and to develop pulmonary disease. Patients receiving a diagnosis of RRP before 3 years of age had significantly higher severity scores, higher frequencies of surgical intervention, and greater likelihood of requiring adjuvant medical therapy. Patients with Medicaid insurance had significantly higher severity scores and required more frequent surgical debridement. Birth by cesarean section appeared to be a significant risk factor for more severe disease and necessity of more frequent surgical intervention. Statistical analysis of the relationships among epidemiological factors, HPV type, and clinical course revealed that patients with HPV-11 and patients younger than 3 years of age at RRP diagnosis are prone to develop more aggressive disease as represented by higher severity scores at endoscopic debridement, more frequent operative debridement procedures per year, a greater requirement for adjuvant therapy, and greater likelihood of tracheal disease with tracheotomy.

To explore the clinical effects of posterior debridement, bone grafting via intervertebral space combined with internal fixation for the treatment of lumbosacral tuberculosis. The clinical data of 32 patients with lumbosacral tuberculosis underwent the procedure of one-stage posterior intervertebral debridement, bone grafting and internal fixation from January 2007 to July 2013 were retrospectively analyzed. There were 17 males and 15 females, aged from 27 to 63 years with an average of (49.8±9.2) years. The course of disease was from 5 to 18 months with the mean of (10.7±3.2) months. There was involved the vertebral body of L₅ in 1 case, the intervertebral space of L₅S₁ in 8 cases, and the vertebral body of L₅ or S₁ combined with intervertebral space of L₅S₁ in 23 cases. VAS, ESR, CRP, the lumbosacral angle, the height of intervertebral space of L₅S₁, and ASIA grade were used to evaluate clinical effects. All the patients were followed up from 18 to 39 months with an average of 21.6 months. Operative time was 120 to 260 min with the mean of 175 min, and intraoperative bleeding was 700 to 1 450 ml with the mean of 1 050 ml. VAS before operation was 8.4±1.6, then descended to 3.5±0.8( P <0.05) on the 3rd month after operation and redescended to the level of 1.7±0.6( P <0.05) at the final follow-up. The ESR and CRP before operation were (48.8±10.2) mm and (58.6±5.6) mg/L, respectively, then decreased to (35.6±6.9) mm and (22.5±4.3) mg/L ( P <0.05) at the 3rd month after operation and returned to the normal level at the final follow-up. The height of intervertebral space of L₅S₁ and lumbosacral angle before operation were (7.7±0.4) mm and (19.3±1.2)°, respectively, then improved to (10.3±0.3) mm and (22.4±1.5)° on the 3rd month after operation( P <0.05), and maintained such level, no obvious lost at later. According to ASIA grade, 8 cases were grade C, 19 were grade D, 5 were grade E before operation, and at final follow-up, 1 case still was grade D, others were grade E. The procedure of posterior debridement, bone grafting via intervertebral space combined with internal fixation is an effective and safe method in treating lumbosacral tuberculosis, it can effectively debride tuberculose focus, maintain the spinal stability, and improve the dysfunction with less complication.

Slough in chronic venous leg ulcers may be associated with delayed healing. The purpose of this study was to assess larval debridement in chronic venous leg ulcers and to assess subsequent effect on healing. All patients with chronic leg ulcers presenting to the leg ulcer service were evaluated for the study. Exclusion criteria were: ankle brachial pressure indices <0.85 or >1.25, no venous reflux on duplex and <20% of ulcer surface covered with slough. Participants were randomly allocated to either 4-layer compression bandaging alone or 4-layer compression bandaging + larvae. Surface areas of ulcer and slough were assessed on day 4; 4-layer compression bandaging was then continued and ulcer size was measured every 2 weeks for up to 12 weeks. A total of 601 patients with chronic leg ulcers were screened between November 2008 and July 2012. Of these, 20 were randomised to 4-layer compression bandaging and 20 to 4-layer compression bandaging + larvae. Median (range) ulcer size was 10.8 (3-21.3) cm(2) and 8.1 (4.3-13.5) cm(2) in the 4-layer compression bandaging and 4-layer compression bandaging + larvae groups, respectively (Mann-Whitney U test, P = 0.184). On day 4, median reduction in slough area was 3.7 cm(2) in the 4-layer compression bandaging group (P < 0.05) and 4.2 cm(2) (P < 0.001) in the 4-layer compression bandaging + larvae group. Median percentage area reduction of slough was 50% in the 4-layer compression bandaging group and 84% in the 4-layer compression bandaging + larvae group (Mann-Whitney U test, P < 0.05). The 12-week healing rate was 73% and 68% in the 4-layer compression bandaging and 4-layer compression bandaging + larvae groups, respectively (Kaplan-Meier analysis, P = 0.664). Larval debridement therapy improves wound debridement in chronic venous leg ulcers treated with multilayer compression bandages. However, no subsequent improvement in ulcer healing was demonstrated. © The Author(s) 2014.

There remains a debate over whether to retain the index anterior cruciate ligament (ACL) graft in the setting of septic arthritis. To evaluate and compare clinical outcomes for the treatment of septic arthritis after ACL reconstruction (ACLR) in those with and without early graft retention. Case series; Level of evidence, 4. The Military Health System was queried for all ACLR procedures performed between 2007 and 2013. Inclusion criteria required active military status, primary ACLR with secondary septic arthritis, and minimum 24-month surveillance. Demographic, clinical, and surgical variables were evaluated using descriptive statistics and regression analysis for factors influencing selected outcomes. Of 9511 ACLR procedures, 31 (0.32%) were identified as having secondary septic arthritis requiring urgent arthroscopic irrigation and debridement and intravenous antibiotics (mean, 6.3 weeks). The majority (62%) were treated in the subacute (2 weeks to 2 months) setting. Index ACLR was performed with a hamstring autograft (n = 17, 55%), soft tissue allograft (n = 11, 35%), and patellar tendon autograft (n = 3, 10%). The graft was retained in 71% (n = 22) of patients, while 29% (n = 9) underwent early graft debridement. At a mean 26.9-month follow-up, 48% of patients (n = 15) had returned to the military. Graft removal was not predictive of return to active duty ( P = .29). The presence of postoperative complications, including symptomatic postinfection arthritis (22.6%) and arthrofibrosis (9.7%), was the only variable predictive of inability to return to duty (odds ratio, 27.5 [95% CI, 3.24-233.47]; P = .002). Seven of 9 patients who underwent graft debridement underwent revision ACLR, and all 7 had stable knees at final follow-up compared with 68% (15/22) in the graft retention group. Arthroscopic debridement with early graft removal and staged revision ACLR remains a viable option for restoring knee stability (100%), although the rate of return to active duty was low in the graft resection group (33%). The risk of knee laxity did not differ based on early graft retention. Time to presentation with graft retention was not associated with a decreased rate of graft laxity.

Gun-shot injuries in UK military casualties - Features associated with wound severity.

2016-05-01

Surgical treatment of high-energy gun-shot wounds (GSWs) to the extremities is challenging. Recent surgical doctrine states that wound tracts from high-energy GSWs should be laid open, however the experience from previous conflicts suggests that some of these injuries can be managed more conservatively. The aim of this study is to firstly characterise the GSW injuries sustained by UK forces, and secondly test the hypothesis that the likely severity of GSWs can be predicted by features of the wound. The UK Military trauma registry was searched for cases injured by GSW in the five years between 01 January 2009 and 31 December 2013: only UK personnel were included. Clinical notes and radiographs were then reviewed. Features associated with energy transfer in extremity wounds in survivors were further examined with number of wound debridements used as a surrogate marker of wound severity. There were 450 cases who met the inclusion criteria. 96 (21%) were fatally injured, with 354 (79%) surviving their injuries. Casualties in the fatality group had a median New Injury Severity Score (NISS) of 75 (IQR 75-75), while the median NISS of the survivors was 12 (IQR 4-48) with 10 survivors having a NISS of 75. In survivors the limbs were most commonly injured (56%). 'Through and through' wounds, where the bullet passes intact through the body, were strongly associated with less requirement for debridement (p<0.0001). When a bullet fragmented there was a significant association with a requirement for a greater number of wound debridements (p=0.0002), as there was if a bullet fractured a bone (p=0.0006). More complex wounds, as indicated by the requirement for repeated debridements, are associated with injuries where the bullet does not pass straight through the body, or where a bone is fractured. Gunshot wounds should be assessed according to the likely energy transferred, extremity wounds without features of high energy transfer do not require extensive exploration. Crown Copyright © 2016.

Snakebites can produce severe local and systemic septic complications as well as being associated with significant overall morbidity and even mortality. A prospective audit was undertaken to determine the bacterial causation of wound infection secondary to snakebite, and attempt to quantify the burden of disease. The audit was undertaken at Ngwelezane Hospital, which provides both regional and tertiary services for north-eastern KwaZulu-Natal Province, South Africa, over a 4-month period. Records of patients who required surgical debridement for extensive skin and soft-tissue necrosis were analysed. At the time of debridement, tissue samples of necrotic or infected tissue were sent for bacteriological analysis as standard of care. Microbiology results were analysed. A total of 164 patients were admitted to hospital for management of snakebite, of whom 57 required surgical debridement and 42 were included in the final microbiological analysis. Children were found to be the most frequent victims of snakebite; 57.8% of patients in this study were aged ≤10 years and 73.7% ≤15 years. Culture showed a single organism in 32/42 cases, two organisms in 8 and no growth in 2. Eight different types of organisms were cultured, five of them more than once. Thirty-five specimens (83.3%) grew Gram-negative Enterobacteriaceae, the most frequent being Morganella morganii and Proteus species. Thirteen specimens (31.0%) grew Enterococcus faecalis. Gram-negative Enterobacteriaceae showed 31.4% sensitivity to ampicillin, 40.0% sensitivity to amoxicillin plus clavulanic acid, 34.3% sensitivity to cefuroxime, 97.1% sensitivity to ceftriaxone, and 100% sensitivity to ciprofloxacin, gentamicin and amikacin. E. faecalis was 92.3% sensitive to amoxicillin, 92.3% sensitive to amoxicillin plus clavulanic acid, 100% sensitive to ciprofloxacin, 92.3% resistant to erythromycin and 100% resistant to ceftriaxone. Children are particularly vulnerable to snakebite, and the consequences can be devastating. While the majority of patients in this study were shown to have secondary bacterial infection, debridement and subsequent wound management is considered the mainstay of treatment. Common organisms are Enterobacteriaceae and enterococci. There appears to be a role for antibiotics in the management of these patients. A good antibiotic policy is strongly advocated.

It is widely accepted that the mechanisms for transducing sensory information reside in the nerve terminals. Occasionally, however, studies have appeared demonstrating that similar mechanisms may exist in the axon to which these terminals are connected. We examined this issue in the cornea, where nerve terminals in the epithelial cell layers are easily accessible for debridement, leaving the underlying stromal (axonal) nerves undisturbed. In isoflurane-anesthetized rats, we recorded extracellularly from single trigeminal ganglion neurons innervating the cornea that are excited by ocular dryness and cooling: low-threshold (<2°C cooling) and high-threshold (>2°C) cold-sensitive plus dry-sensitive neurons playing possible roles in tearing and ocular pain. We found that the responses in both types of neurons to dryness, wetness, and menthol stimuli were effectively abolished by the debridement, indicating that their transduction mechanisms lie in the nerve terminals. However, some responses to the cold, heat, and hyperosmolar stimuli in low-threshold cold-sensitive plus dry-sensitive neurons still remained. Surprisingly, the responses to heat in approximately half of the neurons were augmented after the debridement. We were also able to evoke these residual responses and follow the trajectory of the stromal nerves, which we subsequently confirmed histologically. The residual responses always disappeared when the stromal nerves were cut at the limbus, suggesting that the additional transduction mechanisms for these sensory modalities originated most likely in stromal nerves. The functional significance of these residual and enhanced responses from stromal nerves may be related to the abnormal sensations observed in ocular disease. NEW & NOTEWORTHY In addition to the traditional view that the sensory transduction mechanisms exist in the nerve terminals, we report here that the proximal axons (stromal nerves in the cornea from which these nerve terminals originate) may also be capable of transducing sensory information. We arrived at this conclusion by removing the epithelial cell layers of the cornea in which the nerve terminals reside but leaving the underlying stromal nerves undisturbed.

High-pressure injection injuries to the upper extremity: a review of the literature.

PubMed

Hogan, Christopher J; Ruland, Robert T

2006-07-01

The purpose of this review was to identify the relative impact of injected material, location of injury, time to debridement, injection pressure, infection, and the use of adjuvant steroid medication upon the need for amputation after high-pressure injection injuries to the upper extremity. A Medline literature search extending from 1966 to December 2003 was performed, referencing the key words "high-pressure injection injury," "grease gun injury," "paint gun injury," "pressure gun injury," and "high-pressure injection." The results were limited to the English language and to reports involving human subjects. Each abstract was reviewed to confirm that the described injury had occurred in the upper extremity and that it had truly been a high-pressure injection. The reference pages from each of the papers were reviewed to identify additional reports of high-pressure injection injury. Manuscripts describing injuries resulting from hand held syringes or other low-pressure mechanisms were excluded. All of the manuscripts were analyzed to identify the clinical outcome, age, hand dominance, site of injection, substance injected, injection pressure, elapsed time to wide debridement, use of steroids, and incidence of infection. These variables were subjected to a Pearson chi test to determine their impact upon the need for amputation. Four hundred thirty-five cases of high-pressure injection injury to the upper extremity were identified. The amputation rate after these injuries was 30%. The location of the injury and the material injected contributed significantly to the need for amputation. For injections of paint, paint thinner, gasoline, oil, or jet fuel (organic solvents), the amputation risk was lower if wide surgical debridement occurred within 6 hours of injury. Steroids did not impact the amputation rate or incidence of infection. The presence of infection did not affect the incidence of amputation. The risk of amputation after high-pressure injection injury to the upper extremity is highest with organic solvent injection into the fingers. Injections into the thumb or palm result in a much lower frequency of tissue loss. Emergent surgical debridement reduces the amputation risk after injections of organic solvents. From the available data, no conclusions could be reached regarding functional outcomes, other than amputation, after high-pressure injection injury.

To describe the utilization of clostridial collagenase ointment (CCO) and medicinal honey debridement methods in real-world inpatient and outpatient hospital settings among pressure ulcer (PU) patients and compare the frequency of healthcare re-encounters between CCO- and medicinal honey-treated patients. De-identified hospital discharge records for patients receiving CCO or medicinal honey methods of debridement and having an ICD-9 code for PU were extracted from the US Premier Healthcare Database. Multivariable analysis was used to compare the frequency of inpatient and outpatient revisits up to 6 months after an index encounter for CCO- vs medicinal honey-treated PUs. The study identified 48,267 inpatients and 2,599 outpatients with PUs treated with CCO or medicinal honeys. Among study inpatients, n = 44,725 (93%) were treated with CCO, and n = 3,542 (7%) with medicinal honeys. CCO and medicinal honeys accounted for 1,826 (70%) and 773 (30%), respectively, of study outpatients. In adjusted models, those treated with CCO had lower odds for inpatient readmissions (OR = 0.86, 95% CI = 0.80-0.94) after inpatient index visits, and outpatient re-encounters both after inpatient (OR = 0.73, 95% CI = 0.67-0.79) and outpatient (OR = 0.78, 95% CI = 0.64-0.95) index visits in 6 months of follow-up. The study was observational in nature, and did not adjust for reasons why patients were hospitalized initially, or why they returned to the facility. Although the study adjusted for differences in a variety of demographic, clinical, and hospital characteristics between the treatments, we are not able to rule out selection bias. Patients with CCO-treated PUs returned to inpatient and outpatient hospital settings less often compared with medicinal honey-treated PUs. These results from real-world administrative data help to gain a better understanding of the clinical characteristics of patients with PUs treated with these two debridement methods and the economic implications of debridement choice in the acute care setting.

Treatment of Patellar Tendinopathy Refractory to Surgical Management Using Percutaneous Ultrasonic Tenotomy and Platelet-Rich Plasma Injection: A Case Presentation.

Nanos, Katherine N; Malanga, Gerard A

2015-12-01

Chronic proximal patellar tendinopathy is a common condition in sports medicine that may be refractory to nonoperative treatments, including activity modification, medications, and comprehensive rehabilitation. Percutaneous ultrasonic tenotomy is a recently developed technique designed to cut and debride tendinopathic tissue, thus promoting pain relief and functional recovery. We present a case of a collegiate athlete with chronic proximal patellar tendinopathy who was effectively treated with percutaneous ultrasonic tenotomy after not responding to extensive nonoperative treatment, surgical debridement, and platelet-rich plasma injections. Percutaneous ultrasonic tenotomy can be considered as a treatment option in patients presenting with refractory proximal patellar tendinopathy, including those who do not respond to previous operative intervention.

To determine the role of maggot debridement therapy (MDT) on diabetic foot wound healing, we compared growth related factors in wounds before and after treatment. Furthermore, we utilized human umbilical vein endothelial cells (HUVECs) to explore responses to maggot excretions/secretions on markers of angiogenesis and proliferation. The results showed that there was neo-granulation and angiogenesis in diabetic foot wounds after MDT. Moreover, significant elevation in CD34 and CD68 levels was also observed in treated wounds. In vitro, ES increased HUVEC proliferation, improved tube formation, and increased expression of vascular endothelial growth factor receptor 2 in a dose dependent manner. These results demonstrate that MDT and maggot ES can promote diabetic foot wound healing by up-regulating endothelial cell activity. Copyright © 2016. Published by Elsevier Inc.

Penetrating head injury from angle grinder: A cautionary tale.

Penetrating cranial injury is a potentially life-threatening condition. Injuries resulting from the use of angle grinders are numerous and cause high-velocity penetrating cranial injuries. We present a series of two penetrating head injuries associated with improper use of angle grinder, which resulted in shattering of disc into high velocity missiles with reference to management and prevention. One of those hit on the forehead of the operator and the other on the occipital region of the co-worker at a distance of five meters. The pathophysiological consequence of penetrating head injuries depends on the kinetic energy and trajectory of the object. In the nearby healthcare center the impacted broken disc was removed without realising the consequences and the wound was packed. As the conscious level declined in both, they were referred. CT brain revealed fracture in skull and changes in the brain in both. Expeditious removal of the penetrating foreign body and focal debridement of the scalp, skull, dura, and involved parenchyma and Watertight dural closure were carried out. The most important thing is not to remove the impacted foreign body at the site of accident. Craniectomy around the foreign body, debridement and removal of foreign body without zigzag motion are needed. Removal should be done following original direction of projectile injury. The neurological sequelae following the non missile penetrating head injuries are determined by the severity and location of initial injury as well as the rapidity of the exploration and fastidious debridement.

Repeated Use of Immersive Virtual Reality Therapy to Control Pain during Wound Dressing Changes in Pediatric and Adult Burn Patients

Faber, Albertus W.; Patterson, David R.; Bremer, Marco

2012-01-01

Objective The current study explored whether immersive virtual reality continues to reduce pain (via distraction) during more than one wound care session per patient. Patients: Thirty six patients aged 8 to 57 years (mean age of 27.7 years), with an average of 8.4% total body surface area burned (range .25 to 25.5 TBSA) received bandage changes, and wound cleaning. Methods Each patient received one baseline wound cleaning/debridement session with no-VR (control condition) followed by one or more (up to seven) subsequent wound care sessions during VR. After each wound care session (one session per day), worst pain intensity was measured using a Visual Analogue Thermometer (VAT), the dependent variable. Using a within subjects design, worst pain intensity VAT during wound care with no-VR (baseline, Day 0) was compared to pain during wound care while using immersive virtual reality (up to seven days of wound care during VR). Results Compared to pain during no-VR Baseline (Day 0), pain ratings during wound debridement were statistically lower when patients were in virtual reality on Days 1, 2 and 3, and although not significant beyond day 3, the pattern of results from Days 4, 5, and 6 are consistent with the notion that VR continues to reduce pain when used repeatedly. Conclusions Results from the present study suggest that VR continues to be effective when used for three (or possibly more) treatments during severe burn wound debridement. PMID:23970314

The aim of this study has been to compare the clinical and radiographic outcome of periodontal intrabony defect treatment by open flap debridement alone or in combination with nanocrystalline hydroxyapatite bone substitute application. Thirty patients diagnosed with advanced periodontits were divided into two groups: the control group (OFD), in which an open flap debridement procedure was performed and the test group (OFD+NHA), in which defects were additionally filled with nanocrystalline hydroxyapatite bone substitute material. Plaque index (PI), gingival index (GI), bleeding on probing (BOP), pocket depth (PD), gingival recession (GR) and clinical attachment level (CAL) were measured prior to, then 6 and 12months following treatment. Radiographic depth and width of defects were also evaluated. There were no differences in any clinical and radiographic parameters between the examined groups prior to treatment. After treatment, BOP, GI, PD, CAL, radiographic depth and width parameter values improved statistically significantly in both groups. The PI value did not change, but the GR value increased significantly after treatment. There were no statistical differences in evaluated parameters between OFD and OFD+NHA groups 6 and 12months after treatment. Within the limits of the study, it can be concluded that the additional use of nanocrystalline hydroxyapatite bone substitute material after open flap procedure does not improve clinical and radiographic treatment outcome.

Necrotizing fasciitis of the head and neck is a rare and potentially fatal disease. It is a bacterial infection characterized by spreading along fascia planes and subcutaneous tissue resulting in tissue necrosis and likely death. It is commonly of dental or pharyngeal origin. Factors affecting the success of the treatment are early diagnosis, appropriate antibiotics and surgical debridement. Our study showed eight patients, five males and three females with mean age of 49.25 years (range 20-71 years). Clinical presentations were a rapidly progressing painful neck swelling, fever, dysphagia and trismus. The aetiology varied from idiopathic, pharyngeal/tonsillar infection, trauma and nasal malignancy. There were associated variable comorbidities (diabetes mellitus, HIV infection, hypertension and congestive cardiac failure). All the patients received early and aggressive medical treatment. The earliest time of surgery was 12 h after admission because of the poor financial status of patients. Three cases came in with complications of the disease and were not fit for extensive debridement under general anaesthesia. For them limited and reasonable bed side debridement was done. Mortality was 50 % from multiple organ failure, HIV encephalopathy, aspiration pneumonitis and septicemia. The duration of hospital stay for the patients that died ranged from 1 to 16 days and 4 to 34 days for the survivor. Our study heightens awareness and outlines the management challenges of necrotizing fasciitis of the head and neck in a poor resource setting.

To compare corneal stromal and endothelial cells after photorefractive keratectomy with intraoperative mitomycin C in alcohol-assisted versus mechanical epithelial debridement using confocal microscopy. This prospective randomized comparative study was performed on 88 eyes (44 patients) with myopia up to -6.00 diopters. The right eye of each patient was randomly assigned to either mechanical or alcohol-assisted groups, and the left eye was assigned to the alternate group. Confocal microscopy was performed preoperatively and at 3 months postoperatively. The main outcome measures were epithelial thickness; number of keratocytes in the anterior, mid-, and posterior stroma; and characteristics of the central corneal endothelial cells in terms of density, mean cell area, and polymegathism and hexagonality. Three months after surgery, no statistically significant difference was noted between the study groups in terms of epithelial thickness. We also found no statistically significant difference in central corneal endothelial cells regarding cell density, mean cell area, hexagonality, or polymegathism. Compared with baseline values, the density of mid- and posterior stromal keratocytes showed no significant change in either group, whereas it decreased significantly in the anterior stroma in both groups 3 months after surgery. We found that the adverse effects of photorefractive keratectomy with mitomycin C on central corneal endothelial cells were comparable between the mechanical and alcohol-assisted epithelial debridement groups and the significant decrease in postoperative keratocyte density in anterior stroma was comparable between the two groups. The choice of their application could be left to the discretion of the ophthalmologist.

Infections and complex wounds after ventricular assist device (VAD) placement can result in significant morbidity and mortality. The purpose of this study was to evaluate complex wound management in the VAD patient, and to describe a treatment protocol for these challenging and potentially mortal complications. A retrospective study was performed to examine all patients who underwent continuous flow, second-generation VAD placement at the Hospital of the University of Pennsylvania between March 2008 and April 2013. Overall, 150 VADs were placed, with 12 (8%) patients requiring 15 operative interventions by the plastic surgery services. The most common indication for operative intervention was a complicated wound with VAD exposure (5/12, 41.7%). All patients underwent aggressive operative debridement, and 11/12 (92%) underwent vascularized soft tissue coverage. Flaps commonly utilized included rectus abdominus myocutaneous (n = 4), rectus abdominus muscle (n = 4), pectoralis major (n = 3), and omentum (n = 3). Three patients experienced complications which required a return to the operating room, including 1 flap loss, 1 hematoma, and 1 wound dehiscence requiring further soft tissue coverage. Salvage was achieved, yet a 50% mortality rate in follow-up was noted. Complex wound management in VAD patients can be achieved with aggressive debridement and vascularized soft tissue coverage, most commonly utilizing well-vascularized rectus abdominus muscle or omental flaps. Plastic surgeons should be familiar with the armamentarium at their disposal when approaching these challenging cases as VAD wound complications stand to become an increasingly prevalent issue.

The aim was to evaluate the effect of a chlorhexidine-containing brush-on gel when used as supplement to oral hygiene instructions and mechanical debridement, on peri-implant mucositis in adults. The study group consisted of 38 adults (48-87 years.) with peri-implant mucositis that were consecutively enrolled in three private clinics after informed consent. The study employed a double-blind controlled design with two parallel arms. After baseline registrations, oral hygiene reinforcement and mechanical debridement, the patients were randomly allocated to either a test group with once daily tooth brushing with an oral care brush-on gel containing 0.2% chlorhexidine digluconate (Cervitec Gel) or a control gel group. The duration of the intervention was 12 weeks. The primary outcome was bleeding on probing (BOP) and secondary endpoints were local plaque score (LPS) and pocket probing depth (PPD). The groups were balanced at baseline. The daily use of the chlorhexidine-containing gel resulted in reduced BOP after 4 and 12 weeks compared with the control group (P < 0.05). The PPD was significantly reduced (P < 0.05) after 12 weeks compared to baseline in the test group, but not in the control group. No side effects or adverse events were reported. The present findings indicated moderate but significant improvements of clinical parameters when mechanical debridement was combined with a self-applied oral care brush-on gel for the management of peri-implant mucositis. © 2015 John Wiley & Sons A/S.

To report surgical management and favorable outcome in a case with delayed repair of traumatic laser in situ keratomileusis (LASIK) flap dislocation with shrinkage and folds. A 30-year-old man with a five-year history of bilateral LASIK experienced blunt trauma to his right eye followed by decreased vision for 5 weeks. The surgical management included initially softening the flap by irrigation with balanced salt solution (BSS). The shrinkage folds were carefully and gently stretched by scraping with a 26-gauge cannula accompanied by BSS irrigation. All of the epithelial ingrowth on the flap inner surface and on the bed was thoroughly debrided by scraping and irrigation. After the flap was repositioned to match its original margin, a soft bandage contact lens was placed. At his initial visit, slit-lamp microscopy and optical coherence tomography (OCT) showed shrinkage of the LASIK flap with an elevated margin approximately 3 mm above the original position. The flap covered half of the pupil and had multiple horizontal folds. Two months after surgery, the flap remained well positioned with only faint streaks in the anterior stroma. The uncorrected visual acuity of the right eye was 20/20 with a manifest refraction of Plano. For delayed repair of traumatically dislocated LASIK flaps, sufficient softening by BSS, stretching the shrinkage folds, and thorough debridement of ingrowth epithelium enable resetting the flap and provide satisfactory results.

Scabies is a contagious condition that is transmitted through direct contact with an infected person and has been frequently associated with institutional and healthcare-facility outbreaks. The subtype Norwegian crusted scabies can masquerade as other dermatologic diseases owing to the heavy plaque formation. Successful treatment has been documented in published reports, including oral ivermectin and topical permethrin. Few case studies documenting the treatment of Norwegian crusted scabies have reported the use of surgical debridement as an aid to topical and/or oral treatment when severe plaque formation has been noted. A nursing home patient was admitted to the hospital for severe plaque formation of both feet. A superficial biopsy was negative for both fungus and scabies because of the severity of the plaque formation on both feet. The patient underwent a surgical, diagnostic biopsy of both feet, leading to the diagnosis of Norwegian crusted scabies. A second surgical debridement was then performed to remove the extensive plaque formation and aid the oral ivermectin and topical permethrin treatment. The patient subsequently made a full recovery and was discharged back to the nursing home. At 2 and 6 months after treatment, the patient remained free of scabies infestation, and the surgical wound had healed uneventfully. The present case presentation has demonstrated that surgical debridement can be complementary to the standard topical and oral medications in the treatment of those with Norwegian crusted scabies infestation.

Management of traumatic hemipelvectomy: an institutional experience on four consecutive cases

PubMed Central

2013-01-01

Background and objective The incidence of traumatic hemipelvectomy is rare, but it is a devastating injury. Recently, an increasing number of patients with traumatic hemipelvectomy are admitted to trauma centers alive due to improvements of the pre-hospital care. Successful management requires prompt recognition of the nature of this injury and meticulous surgical technique. We present our successful experiences on four cases of traumatic hemipelvectomy in the past nine years. Patients and methods Four cases with traumatic hemipelvectomy were admited to our hospital from June 21, 2002 to September 3, 2011. All injuries occurred due to vehicle accident and all patients were in a state of severe hypotension, with two of them having anal lacerations. These four cases were treated immediately with resuscitation, control of hemorrhage, early amputation, repeated debridement and closure of the wounds. An angiographic embolization was given to control hemorrhage in two of the cases preoperatively. One case underwent fecal diversion. Wound infection occurred in all of cases which was successfully controlled by repeated debridements, effective anti-biotic regimen, split-thickness skin grafts. Results All four cases were saved successfully with well-healed wounds during follow up from 1 to 7 years. They were able to walk by themself using crutches. Conclusion Adhering to the surgery principles of damage control including appropriate resuscitation, hemorrhage control, coagulopathy correction and multiple debridements and closure of the wounds in reasonable period of time can save the life of cases suffering from severe pelvic ring injury.

2017-03-09

Infection after osteosynthesis is an important complication with significant morbidity and even mortality. These infections are often caused by biofilm-producing bacteria. Treatment algorithms dictate an aggressive approach with surgical debridement and antibiotic treatment. The aim of this study is to analyze the effect of such an aggressive standardized treatment regime with implant retention for acute, existing <3 weeks, infection after osteosynthesis. We conducted a retrospective 2-year cohort in a single, level 1 trauma center on infection occurring within 12 months following any osteosynthesis surgery. The standardized treatment regime consisted of implant retention, thorough surgical debridement, and immediate antibiotic combination therapy with rifampicin. The primary outcome was success. Success was defined as consolidation of the fracture and resolved symptoms of infection. Culture and susceptibility testing were performed to identify bacteria and resistance patterns. Univariate analysis was conducted on patient-related factors in association with primary success and antibiotic resistance. Forty-nine patients were included for analysis. The primary success rate was 63% and overall success rate 88%. Factors negatively associated with primary success were the following: Gustilo classification (P = 0.023), higher number of debridements needed (P = 0.015), inability of primary closure (P = 0.017), and subsequent application of vacuum therapy (P = 0.030). Adherence to the treatment regime was positively related to primary success (P = 0.034). The described treatment protocol results in high success rates, comparable with success rates achieved in staged exchange in prosthetic joint infection treatment.

2012-01-01

Extensive large sebaceous cysts on the scotum are rare and present a problem only when infected or when cosmesis is deemed unacceptable by the patient. Fournier's gangrene is an infective condition with a high death rate. We describe a case of Fournier's gangrene in a patient masked by multiple large infected scrotal sebaceous cysts. A 32-year-old man with a history of alcohol dependency, cirrhosis and multiple scrotal sebaceous cysts presented with acute scrotal pain and erythema. Necrosis of the area became evident within 12 h of his admission and an emergency surgical debridement was performed. The wound was left open to heal via secondary intention over 4 weeks without complication. Fournier's gangrene is a rapidly progressive condition and early surgical debridement is crucial to achieve satisfactory outcomes. In this case, prompt intervention allowed a large scrotal defect to heal without the need for skin grafting. PMID:22669874

2018-01-01

Scrotal loss from Fournier's gangrene can be a devastating injury with esthetic and functional consequences. Local reconstructive options can be limited by the presence of infection or the loss of neighboring tissue from debridement. Integra TM bilayer matrix wound dressing is a well-established reconstructive modality, but only one report exists of its use in scrotal reconstruction and this was not in the setting of Fournier's gangrene. We report the successful use of Integra and a subsequent split-thickness skin graft for reconstruction of the anterior scrotum and coverage of the exposed testes in a 43-year-old man who developed Group A Streptococcus necrotizing fasciitis of his right lower extremity, groin, and scrotum requiring serial operative debridements. Stable testicular coverage was achieved with closely matched skin and minimal donor-site morbidity. Further study and a larger sample size will be necessary to better understand the advantages and disadvantages of scrotal reconstruction with Integra.

Reconstructive challenges in war wounds

Bhandari, Prem Singh; Maurya, Sanjay; Mukherjee, Mrinal Kanti

2012-01-01

War wounds are devastating with extensive soft tissue and osseous destruction and heavy contamination. War casualties generally reach the reconstructive surgery centre after a delayed period due to additional injuries to the vital organs. This delay in their transfer to a tertiary care centre is responsible for progressive deterioration in wound conditions. In the prevailing circumstances, a majority of war wounds undergo delayed reconstruction, after a series of debridements. In the recent military conflicts, hydrosurgery jet debridement and negative pressure wound therapy have been successfully used in the preparation of war wounds. In war injuries, due to a heavy casualty load, a faster and reliable method of reconstruction is aimed at. Pedicle flaps in extremities provide rapid and reliable cover in extremity wounds. Large complex defects can be reconstructed using microvascular free flaps in a single stage. This article highlights the peculiarities and the challenges encountered in the reconstruction of these ghastly wounds. PMID:23162233

Endoscopic Debridement for Treatment of Chronic Plantar Fasciitis: An Innovative Technique and Prospective Study of 46 Consecutive Patients.

Cottom, James M; Maker, Jared M; Richardson, Phillip; Baker, Joseph S

2016-01-01

Plantar fasciitis is one the most common pathologies treated by foot and ankle surgeons. When nonoperative therapy fails, surgical intervention might be warranted. Various surgical procedures are available for the treatment of recalcitrant plantar fasciitis. The most common surgical management typically consists of open versus endoscopic plantar fascia release. Comorbidities associated with the release of the plantar fascia have been documented, including lateral column overload and metatarsalgia. We present an innovative technique for this painful condition that is minimally invasive, allows visualization of the plantar fascia, and maintains the integrity of the fascia. Our hypothesis was that the use of endoscopic debridement of the plantar fascia with or without heel spur resection would provide a minimally invasive technique with acceptable patient outcomes.

Mucormycosis is a potentially fatal complication of diabetes. The rhino-orbito-cerebral form is the most common presentation, however, rarely other types can also be seen. We describe the case of a 4½ -year-old boy not previously known to be a diabetic who presented to the plastic surgery department for gangrene of the left middle finger with surrounding erythema and induration. After the diagnosis of diabetes and initial treatment, pus from the wound showed broad aseptate hyphae suggestive of mucormycosis which was further confirmed on culture. Aggressive surgical debridement including amputation, antifungal treatment and glycemic control achieved a complete cure. Cutaneous mucormycosis is a rare complication of type 1 diabetes mellitus and can even be seen at the onset of diabetes. High index of suspicion, timely antifungal treatment and aggressive surgical debridement usually lead to recovery in the localized form of the disease.

Pancreatic and duodenal injuries: keep it simple.

Rickard, Matthew J F X; Brohi, Karim; Bautz, Peter C

2005-07-01

The management of pancreatic and duodenal trauma has moved away from complex reconstructive procedures to simpler methods in keeping with the trend towards organ-specific, damage control surgery. A retrospective case note review was undertaken over a 30-month period to evaluate a simplified protocol for the management of these injuries. Of 100 consecutive patients there were 51 with pancreatic injury, 30 with a duodenal injury and 19 with combined pancreaticoduodenal trauma. Overall mortality was 18.0%, with a late mortality (after 24 h) of 9.9%. This is comparable to previous studies. Morbidity from abscesses, fistulas and anastomotic breakdown was acceptably low. The concept of staged laparotomy can be successfully applied to wounds of the pancreas and duodenum. Debridement of devitalized tissue and drainage can be employed for most cases of pancreatic trauma. Most duodenal injuries can be managed with debridement and primary repair. Temporary exclusion and reoperation should be employed for unstable patients.

Soft-Tissue Injuries Associated With High-Energy Extremity Trauma: Principles of Management.

PubMed

Norris; Kellam

1997-01-01

The management of high-energy extremity trauma has evolved over the past several decades, and appropriate treatment of associated soft-tissue injuries has proved to be an important factor in achieving a satisfactory outcome. Early evaluation of the severely injured extremity is crucial. Severe closed injuries require serial observation of the soft tissues and early skeletal stabilization. Open injuries require early aggressive debridement of the soft tissues followed by skeletal stabilization. Temporary wound dressings should remain in place until definitive soft-tissue coverage has been obtained. Definitive soft-tissue closure will be expedited by serial debridements performed every 48 to 72 hours in a sterile environment. Skeletal union is facilitated by early bone grafting and/or modification of the stabilizing device. Aggressive rehabilitation, includ-ing early social reintegration, are crucial for a good functional outcome. Adherence to protocols is especially beneficial in the management of salvageable severely injured extremities.

Severe burns of hands and arms are complex and challenging injuries. The Standard of care (SOC) - necrosectomy with skin grafting - is often associated with poor functional or aesthetic outcome. Enzymatic debridement (ED) is considered one promising alternative but, until recently, results proved to be highly variable. Between 04/2014 and 04/2015, 16 patients with deep partial- to full-thickness burns of the upper extremities underwent enzymatic debridement (ED) in our Burn Center and were evaluated for extent of additional surgery, wound healing, pain management and functional parameters. Following ED, no further surgical intervention was required in 53.8 % of the study population. In patients who required surgical treatment, the the skin-grafted area could be reduced by 37.0 % when compared to initial assessment. Time from injury to ED was 24.4 h and patients were able to start physical therapy after 2.0 days but suffered from prolonged wound closure (28.0 days). Regionally administered anesthesia proved to be superior to pain medication alone as pain levels and consumed morphine-equivalent were lower. Post-demission follow-up showed good functional results and pain levels with low scores in two self-report questionnaires (DASH, PRWE-G) but 3 patients reported increased susceptibility to shear stress. Based on these early experiences, we developed a 3-step algorithm for consecutive patients allowing appropriate and individualized treatment selection. We see a potential benefit for ED in the treatment of severely burned hands and forearms but further investigations and proper prospective, randomized controlled trials are needed to statistically support any outlined assumptions.

To report a rare case of fungal spondylodiscitis in a patient recovered from H7N9 virus infection and perform a literature review of the different characteristics of Candida and Aspergillus spondylodiscitis, we reviewed cases of spondylodiscitis caused by Candida and Aspergillus species. Data, including patients’ information, pathogenic species, treatment strategy, outcomes, and relapses, were collected and summarized. The characteristics of Candida and Aspergillus spondylodiscitis were compared to see if any differences in clinical features, management, or consequences could be detected. The subject of the case study was first misdiagnosed as having a vertebral tumor, and then, following open biopsy, was diagnosed as having fungal spondylodiscitis. The patient made a good recovery following radical debridement. Seventy-seven additional cases of Candida spondylodiscitis and 94 cases of Aspergillus spondylodiscitis were identified in the literature. Patients with Candida spondylodiscitis tended to have a better outcome than patients with Aspergillus spondylodiscitis (cure rate 92.3% vs. 70.2%). Candida was found more frequently (47.8%) than Aspergillus (26.7%) in blood cultures, while neurological deficits were observed more often in patients with Aspergillus spondylodiscitis (43.6% vs. 25.6%). Candida spinal infections were more often treated by radical debridement (60.5% vs. 39.6%). Patients with Candida spondylodiscitis have better outcomes, which may be associated with prompt recognition, radical surgical debridement, and azoles therapy. A good outcome can be expected in fungal spondylodiscitis with appropriate operations and anti-fungal drugs. PMID:27819134

Contemporary diagnosis and management of Fournier’s gangrene

Khourdaji, Iyad; Burks, Frank; Killinger, Kim A.

2015-01-01

Fournier’s gangrene, an obliterative endarteritis of the subcutaneous arteries resulting in gangrene of the overlying skin, is a rare but severe infective necrotizing fasciitis of the external genitalia. Mainly associated with men and those over the age of 50, Fournier’s gangrene has been shown to have a predilection for patients with diabetes as well as people who are long-term alcohol misusers. The nidus for the synergistic polymicrobial infection is usually located in the genitourinary tract, lower gastointestinal tract or skin. Early diagnosis remains imperative as rapid progression of the gangrene can lead to multiorgan failure and death. The diagnosis is often made clinically, although radiography can be helpful when the diagnosis or the extent of the disease is difficult to discern. The Laboratory Risk Indicator for Necrotizing Fasciitis score can be used to stratify patients into low, moderate or high risk and the Fournier’s Gangrene Severity Index (FGSI) can also be used to determine the severity and prognosis of Fournier’s gangrene. Mainstays of treatment include rapid and aggressive surgical debridement of necrotized tissue, hemodynamic support with urgent resuscitation with fluids, and broad-spectrum parental antibiotics. After initial radical debridement, open wounds are generally managed with sterile dressings and negative-pressure wound therapy. In cases of severe perineal involvement, colostomy has been used for fecal diversion or alternatively, the Flexi-Seal Fecal Management System can be utilized to prevent fecal contamination of the wound. After extensive debridement, many patients sustain significant defects of the skin and soft tissue, creating a need for reconstructive surgery for satisfactory functional and cosmetic results.

2011-01-01

Background Breast gangrene is rare in surgical practice. Gangrene of breast can be idiopathic or secondary to some causative factor. Antibiotics and debridement are used for management. Acute inflammatory infiltrate, severe necrosis of breast tissue, necrotizing arteritis, and venous thrombosis is observed on histopathology. The aim of was to study patients who had breast gangrene. Methods A prospective study of 10 patients who had breast gangrene over a period of 6 years were analyzed Results All the patients in the study group were female. Total of 10 patients were encountered who had breast gangrene. Six patients presented with breast gangrene on the right breast whereas four had on left breast. Out of 10 patients, three had breast abscess after teeth bite followed by gangrene, one had iatrogenic trauma by needle aspiration of erythematous area of breast under septic conditions. Four had history of application of belladonna on cutaneous breast abscess and had then gangrene. All were lactating female. Amongst the rest two were elderly, one of which was a diabetic who had gangrene of breast and had no application of belladonna. All except one had debridement under cover of broad spectrum antibiotics. Three patients had grafting to cover the raw area. Conclusion Breast gangrene occurs rarely. Etiology is variable and mutifactorial. Teeth bite while lactation and the iatrogenic trauma by needle aspiration of breast abscess under unsterlised conditions could be causative. Uncontrolled diabetes can be one more causative factor for the breast gangrene. Belladonna application as a topical agent could be inciting factor. Sometimes gangrene of breast can be idiopathic. Treatment is antibiotics and debridement. PMID:21854557

Summary Objectives. Fournier’s gangrene (FG), though rare, is a life-threatening extensive fulminant infection of the genitals, perineum, or abdominal wall caused by a mixture of aerobic and anaerobic micro-organisms. Early and aggressive surgical debridement of the necrotic tissue and complete antibiotic coverage are the gold standards in treating FG. The purpose of our study was to assess the role of MEBO (moist exposed burn ointment) in topical treatment of the wound secondary to surgical debridement. Methods. Eleven patients (age range, 40-75 yr; mean, 55 yr) were admitted to the clinical facilities of the Department of Urology at Al Sabah Hospital, Kuwait, suffering from Fournier’s gangrene, in the 31-month period between January 2004 and July 2006. All these patients were treated with broad-spectrum triple antimicrobial therapy as well as extensive debridement of necrotic tissue. The resultant wounds were treated with MEBO in six randomly selected patients and with a placebo in the remaining five patients. Results. The duration of hospital stay was reduced by 41.7% in the MEBO-treated group (30.0 vs 51.5 days) and pain control of pain was faster, which could be attributed to the faster control of infection and wound healing in this group. Conclusion. A combination of appropriate antibiotic coverage and aggressive surgical therapy is mandatory for the treatment of FG. MEBO promotes the healing of the resulting, quite extensive wound, reducing pain and controlling infection. It is a also a cost-effective therapy as it accelerates healing and reduces hospital stay by 41.7%. PMID:21991105

Preventing and Treating Peri-Implantitis: A Cost-Effectiveness Analysis.

PubMed

Schwendicke, Falk; Tu, Yu-Kang; Stolpe, Michael

2015-09-01

A large number of treatments for peri-implantitis are available, but their cost-effectiveness remains uncertain. This study evaluates the cost-effectiveness of preventing and treating peri-implantitis. A Markov model was constructed that followed each implant over 20 years. Supportive implant therapy (SIT) for managing peri-implant mucositis and preventing development of peri-implantitis was either provided or not. Risk of peri-implantitis was assumed to be affected by SIT and the patient's risk profile. If peri-implantitis occurred, 11 treatment strategies (non-surgical or surgical debridement alone or combined with adjunct therapies) were compared. Treatments and risk profiles determined disease progression. Modeling was performed based on systematically collected data. Primary outcomes were costs and proportion of lost implants, as assessed via Monte Carlo microsimulations. Not providing SIT and performing only non-surgical debridement was both least costly and least effective. The next best (more costly and effective) option was to provide SIT and perform surgical debridement (additional 0.89 euros per 1% fewer implants lost). The most effective option included bone grafts, membranes, and laser treatment (56 euros per 1%). For patients at high risk, the cost-effectiveness of SIT increased, whereas in low-risk groups, a cost-optimized strategy was cost-effective. Although clinical decision-making will be guided mainly by clinical condition, cost-effectiveness analyses might add another perspective. Based on these findings, an unambiguous comparative effectiveness ranking was not established. However, cost-effectiveness was predominantly determined by provision of SIT and initial treatment costs. Transferability of these findings to other healthcare systems needs further confirmation.

Objective: Chemical warfare agents are potential threats to military personnel and civilians. The potential for associated traumatic injuries is significant. Damage control surgery could expose medical personnel to agents contaminating the wounds. The objectives of this study were to demonstrate efficacy of surgical decontamination and assess exposure risk to attending personnel. Methods: Weanling pigs were randomly assigned to 2 of 4 debridement tools (scalpel, Bovie® knife, Fugo Blade®, and Versajet™ Hydrosurgery System). Penetrating traumatic wounds were created over the shoulder and thigh and then exposed to liquid sulfur mustard (HD) for 60 minutes. Excisional debridement of the injuries was performed while vapors over each site were collected. Gas chromatography was used to measure HD in samples of collected vapors. Unbound HD was quantified in presurgical wound swabs, excised tissues, and peripheral tissue biopsies following solvent extraction. Results: Excisional debridement produced agent-free wound beds (surgical decontamination). A significant amount of HD vapor was detected above the surgical fields with each tool. Apart from the Versajet™ producing significantly lower levels of HD detected over thigh wounds compared with those treated using the scalpel, there were no differences in the amount of agent detected among the tools. All measured levels significantly exceeded established safety limits. Vesicating levels of unbound HD were extracted from excised tissue. There was no measured lateral spreading of HD beyond the surgical margins. Conclusions: There is significant occupational exposure risk to HD during surgical procedures designed to stabilize agent-contaminated wounds. If appropriate protective measures are taken, surgical decontamination is both effective and safe. PMID:18716652

Acute invasive fungal sinusitis (AIFS) is a frequently fatal infection for which extensive and debilitating surgical debridement is a mainstay of therapy. Resulting defects are often composite in nature, mandating free tissue-transfer reconstruction. Outcomes data for free flap reconstruction are limited. The purpose of this study was to examine surgical outcomes and survival in patients undergoing free flap transfer following invasive fungal sinusitis. Retrospective case series. Between 1995 and 2015, patients undergoing operative debridement for AIFS were identified. Surgical records were used to identify survivors of acute infection who subsequently underwent free flap reconstructive surgery. Patient demographics, cause of immune compromise, defect description, flap type, perioperative complications, indications for revision surgery, functional outcomes, and long-term survival were reviewed. Forty-four patients were treated for AIFS, of those, 30 (68%) survived acute infection. Ten patients underwent maxillectomy, six with orbital exenteration, and were designated candidates for reconstruction. Eight patients underwent reconstruction. Median time from debridement to reconstruction was 67.5 days. Flap types included latissimus dorsi, scapula, anterolateral thigh, rectus, radial forearm, and fibula. Median follow-up was 7.7 months. No perioperative complications were encountered, and all subjects remained disease-free, able to speak and eat normally without prosthetic supplementation. Seven patients (87%) are currently alive. Reconstruction of defects left by invasive fungal sinusitis using free-tissue transfer resulted in successful flap survival, with no disease recurrence for all defects and flap types reviewed. Survivors of AIFS are able to tolerate midface reconstruction, with favorable functional outcomes and survival rates. 4.

This was a retrospective consecutive case series of 28 fractures with Orthopaedic Trauma Association (OTA)-type 43-B and 43-C open pilon fractures. Mean length of follow-up was 36 months and minimum of 1 year. Ten fractures were Gustilo and Anderson grade IIIB, and the remaining fractures were grades I-IIIA. Patients were initially treated with spanning external fixation and staged wound debridement followed by osteosynthesis of the articular surface. Metaphyseal fixation was by either plate fixation or Ilizarov frame. The primary outcome was the incidence of deep tissue infection requiring surgery. Secondary outcomes included the incidence of other complications (nonunion, malunion, amputation) and functional outcomes (Short Musculoskeletal Functional Assessment Questionnaire and AAOS Foot and Ankle Questionnaire). Four patients developed deep tissue infections, three in the internal fixation group and one in the Ilizarov group, and all were treated successfully with staged debridement. There were two delayed unions required bone grafting, and infection-free union was ultimately achieved in all fractures. Two patients underwent arthrodesis secondary to post-traumatic arthritis, while no patients experienced malunions or amputations. The use of staged wound debridement in conjunction with either plate fixation or Ilizarov frame achieves low rates of wound infection and stable fixation after anatomic joint reconstruction for OTA-type 43-B and 43-C open pilon fractures.

This report describes two cases of acute spondylodiscitis, caused by, complicating two different conditions: microdiscectomy for herniated nucleus pulposus and decompressing laminotomy for spinal stenosis. To describe a rare and life-threatening spinal infection and discuss its successful management. To our knowledge, no published reports in the English language have described this potentially devastating infection as a complication of elective noninstrumented discectomy or decompressive laminotomy. Two cases of a very early onset of acute spondylodiscitis, caused by, after minimally invasive lumbar spine surgeries are presented. The elapsed time between these two complications was 1 week. The clinical presentation was characteristically stormy in both cases. On postoperative day 2, the patients developed high fever with intense chills and concomitant acute low back pain rapidly increasing in severity. The overall clinical appearance was alarming. The patients were carefully investigated immediately and scrutinized for possible origin of the infection. Treatment consisted of prompt intravenous antibiotics and surgical debridement. The history and clinical manifestations of postoperative spondylodiscitis were corroborated with magnetic resonance imaging findings and bacteriologic and hematologic laboratory examination. Blood cultures revealed as the responsible pathogenic microorganism. The source of the pathogens was contaminated normal saline used for surgical lavage. Both patients were able to completely resume their previous occupations after aggressive surgical debridement/irrigation and 3 months of antibiotic treatment. may become a potential pathogen, causing severe spinal infection after elective surgery. For prompt diagnosis and effective treatment of this life-threatening infection, one should maintain high index of suspicion and should not procrastinate in initiating treatment, which should consist of appropriate intravenous antibiotics and surgical debridement.

Infected pancreatic necrosis (IPN) is one of the most severe complications of acute pancreatitis (AP). Sequential surgical debridement represents one of the most effective treatments in terms of morbidity and mortality. The aim of this paper is to describe the quality of life and long-term results (e.g., nutritional, muscular, and pancreatic function) of patients treated by sequential necrosectomy at the Department of Surgery of the University of Insubria (Varese, Italy). Data were collected on patients undergoing sequential surgical debridement as treatment for IPN. The severity of AP was evaluated using the Ranson criteria, the Acute Physiology and Chronic Health Evaluation (APACHE II) Score, and the Sepsis Score, as well as the extent of necrosis. The surgical approach was through a midline or subcostal laparotomy, followed by exploration of the peritoneal cavity, wide debridement, and peritoneal lavage. The abdomen was either left open or closed partially with a surgical zipper, with multiple re-laparotomies scheduled until debridement of necrotic tissue was complete. The long-term evaluation focused on late morbidity, performance status, and abdominal wall function. In the majority of patients (68%), mixed flora were isolated. Pseudomonas aeruginosa was the microorganism identified most commonly (59%), often associated with Candida albicans or C. glabrata. The mean total hospital stay was 71+/-38 days (range 13-146 days), of which 24+/-19 days (range 0-66 days) were in the intensive care unit. Eight patients died, the deaths being caused by multiple organ dysfunction syndrome in seven patients and hemorrhage from the splenic artery in one. Normal exocrine and endocrine pancreatic function was observed in 28 patients (88%). At discharge, four patients had steatorrhea, which was temporary. Eight patients (23%) developed pancreatic pseudocysts, and in six, cystogastostomy was performed. Most patients (29/32, 91%) developed a post-operative hernia, but only five required surgical repair. All patients had a Short Form (SF)-36 score>60%, and 20 of the 32 patients (68%) had scores>70-80% (good quality of life). The worst scores were related to alcoholic pancreatitis. The degree of pancreatic failure (exocrine and endocrine function) is not related to the amount of pancreatic necrosis. Even with a need for repeated laparotomy and multiple surgical procedures, the abdominal wall capacity as well as long-term quality of life remain excellent.

Andersson lesion is a well-known complication in ankylosing spondylitis. Recently, owing to the worry about the healing of fracture, some scholars advocated additional anterior surgery or other procedures were necessary, which increase the risk of the nerve injury. The purpose of this study is to introduce our experience and to explore the efficacy and feasibility of posterior wedge osteotomy and debridement through Andersson Lesion for surgical treatment of severe kyphosis in ankylosing spondylitis. From January 2012 to January 2014, a retrospective study of 14 Andersson lesion patients with severe kyphosis in ankylosing spondylitis treated with surgery was completed with an at least 2-year follow-up. The debridement procedure, before posterior wedge osteotomy in posterior approach, must scrape all sclerosis bone until healthy cancellous bone appears. Radiographic and clinical results and complications were assessed with an average follow-up of 24 months. The CT scan was obtained preoperatively and at the final follow-up to assess the displacement of the fracture preoperatively, the safety of screw insertion, the healing of the fracture at the final follow-up. The Bridwell interbody fusion grading system was used to assess the healing of the fracture. Local kyphosis was substantially corrected from 51.7 ± 15.6 to 7.1 ± 19.5, with a mean correction of 44°. The global kyphosis (GK) changed from 60.6 ± 28.3 to 20.3 ± 10.3 (P = 0.000). The mean VAS back pain scores decreased from 6.7 ± 0.8 preoperatively to 0.75 ± 0.6 after a 2-year follow-up (P = 0.000). The ODI score improved from 60.56 ± 15.1% preoperatively to 23.46 ± 8.2% after a 2-year follow-up (P = 0.000). The CT scan showed solid fusion at the level of the AL, and no internal fixation loose. All patients achieved grade 1 fusion. No major complication occurred. The posterior wedge osteotomy and debridement through AL can be used to correct the severe kyphosis in ankylosing spondylitis, achieving favorable clinical outcomes, good fusion, and satisfactory deformity correction.

Patients with necrotizing fasciitis are managed with multiple prompt, radical surgical debridements and critical care support. Debridement and reconstruction are often provided by different surgical teams. Anecdotally, single-specialty management seemed to be a more efficient management strategy. This study aimed to investigate and compare the outcomes of management by plastic surgery versus multiple disciplines through a retrospective economic and clinical analysis of patients with necrotizing fasciitis treated over 8 years. We also present 3 index cases for which our service functioned as the primary management team. Necrotizing fasciitis cases evaluated and treated by our department, covering both Level I and Level II Trauma Centers, were reviewed for total charges, length of hospital stay, length of intensive care unit (ICU) stay, and number of procedures. The admission Acute Physiology and Chronic Health Evaluation II score was calculated for each patient. Three comparative index cases of upper extremity necrotizing fasciitis managed primarily by the plastic surgery team are presented in greater detail. Patients managed primarily by the plastic surgery service had equivalent Acute Physiology and Chronic Health Evaluation II scores to patients managed by multiple services for their necrotizing fasciitis, with the average score higher for patients managed by plastic surgery alone. In a case-matched series of upper extremity necrotizing fasciitis, the patients admitted directly to plastic surgery had shorter average lengths of hospital and ICU stays as well as decreased total number of procedures, resulting in decreased average total hospital charges. There were no amputations among the cases treated primarily by the plastic surgery. The patients also required smaller areas of reconstruction with skin grafting despite large initial areas of debridement compared to those whose reconstructive teams differed from the team performing the debridement. Improved economic and clinical outcomes-as indicated by the reduced lengths of overall and ICU stay, the reduced number of procedures, none of the cases requiring amputation, and the reduced need for skin grafting-may be attainable when the surgeon eventually performing the reconstruction is involved early in management. We propose that, in the interest of improving patient care, a closer collaboration should be established between the reconstructive and primary managing teams.

Background: Photodynamic therapy (PDT) is a method of microbial reduction which can benefit periodontal treatment in areas of difficult access, such as deep pockets and furcations. The aim of this randomized controlled clinical trial was to evaluate the effects of PDT as an adjunct to full-mouth ultrasonic debridement in the treatment of severe chronic periodontitis. Material and Methods: Twenty-two patients with at least one pocket with a probing depth (PD) of ≥7 mm and one pocket with a PD of ≥5 mm and bleeding on probing (BOP) on each side of the mouth were included, characterizing a split mouth design. The control group underwent full-mouth ultrasonic debridement and the test group received the same treatment associated with PDT. The PDT was performed on only one side of the mouth and the initial step consisted of subgingival irrigation with 0.005% methylene blue dye. Two minutes after applying the photosensitizer, the low power laser - AsGaAl (Photon Lase III - PL7336, DMC, São Carlos -São Paulo, Brazil) was applied (660 nm, 100 mW, 9 J, 90 seconds per site, 320 J/cm2, diameter tip 600 µm).The following clinical parameters were evaluated: plaque index, gingival index, BOP, gingival recession (GR), PD, and clinical attachment level (CAL). All parameters were collected before, 1, 3 and 6 months after treatment. Results: An improvement in BOP, PD and CAL was observed after treatment, in both groups, but without any difference between them. After 6 months, the PD decreased from 5.11±0.56 mm to 2.83±0.47 mm in the test group (p<0.05) and from 5.15±0.46 mm to 2.83±0.40 mm in the control group (p<0.05). The CAL changed, after 6 months, from 5.49±0.76 mm to 3.41±0.84 mm in the test group (p<0.05) and from 5.53±0.54 to 3.39±0.51 mm in the control group (p<0.05). Conclusion: Both approaches resulted in significant clinical improvements in the treatment of severe chronic periodontits, however, the PDT did not provide any additional benefit to those obtained with full-mouth ultrasonic debridement used alone.

The presentation and clinical course of mucoid degeneration of the anterior cruciate ligament (MD-ACL) are poorly documented within the literature. Subsequently, it is under-diagnosed and the optimal management strategy remains ill-defined. Here, we characterize the syndrome associated with MD-ACL and compare the natural clinical course with the outcomes of arthroscopic management. Thirty-one patients with radiological features of MD-ACL over a 2-year period had their clinical notes retrospectively reviewed. Seven patients underwent arthroscopic debridement of the ACL for MD. These were followed up for a minimum of 2 years and an average of 2.8 years from surgery. The remainder were managed conservatively ( n  = 24) and were followed up for a minimum of 2 years and an average of 4.0 years. The notch width index (NWI) and associated pathology was noted. Primary outcome measures were presence of knee pain and use of analgesia. Secondary outcome measures were the Oxford and Lysholm knee scores. The most commonly reported symptoms were posterior knee pain (77.4%) and limitation of terminal flexion (58.1%). All patients who underwent arthroscopic debridement were pain and analgesia free at follow-up. Of the patients who did not undergo arthroscopic surgery, three patients had knee replacement surgery and three were lost to follow-up. The remaining patients, 14/18 (77.8%), reported knee pain and regular analgesia use at follow-up, which was significantly more than the arthroscopic debridement group ( p  < 0.01). The knee scores were significantly better in the arthroscopic debridement group at follow-up (Oxford knee score: 45 vs 34; Lysholm: 92 vs 67; p  < 0.01). Furthermore, the postoperative improvement in the Oxford knee and Lysholm scores compared with preoperatively was 12.1 and 31.8 points, respectively ( p  < 0.01). The NWI was increased in patients with mild-to-severe osteoarthritis (0.266 vs 0.273; p  < 0.05). MD-ACL should be considered in patients who report posterior knee pain, limitation of terminal flexion, and it can be associated with other knee pathologies. MD-ACL can be successfully managed with arthroscopic radio frequency debulking with improvement in quality of life at follow-up.

The choice of surgical methods for lumbosacral tuberculosis is controversial due to the complex anterior anatomy and peculiar biomechanics of the lumbosacral junction. The objective of this study was to explore the clinical effect of posterior intervertebral space debridement with annular bone graft fusion and fixation for the treatment of lumbosacral tuberculosis. We retrospectively analysed data from 23 patients with lumbosacral tuberculosis who had undergone posterior intervertebral space debridement with annular bone fusion and fixation between January 2008 and September 2014. The mean age of the patients was 49.0 years (range, 27-71), and the mean duration of disease until treatment was 10.2 months (range, 6-20). The lumbosacral angle, visual analogue scale (VAS) score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, American Spinal Injury Association (ASIA) grade and Social Functioning-36 (SF-36) score were determined to ascertain the clinical effects of the treatment. All patients underwent follow-up observation. The mean follow-up time was 34.2 months (range, 18-45), the mean operation time was 167.0 min (range, 130-210) and the mean blood loss was 767.4 ml (range, 500-1150). The lumbosacral angle was 21.0° ± 2.1° before operation, rising to 28.8° ± 1.7° after operation (p < 0.05) and being maintained thereafter. The mean VAS score before operation was 8.1 ± 0.6, decreasing to 1.2 ± 0.5 (p < 0.05) at the final follow-up. The mean ESR and CRP values were 49.1 ± 5.6 mm and 64.9 ± 11.9 mg/L, respectively, before operation, decreasing to normal at the final follow-up. The preoperative ASIA grade was C in 6 patients, D in 12 and E in 5. At the final follow-up, all patients had an ASIA grade of E except for one patient with a grade of D. For all patients, the SF-36 score at the final follow-up was higher than the preoperative and postoperative scores. Posterior intervertebral space debridement with annular bone graft fusion and fixation is an effective treatment for lumbosacral spine tuberculosis.

[Posterosuperior impingement of the shoulder in the athlete: results of arthroscopic debridement in 75 patients].

PubMed

Riand, N; Boulahia, A; Walch, G

The painful shoulder is a well-recognized clinical entity in throwers although the pathogenic mechanisms involved are still debated. In 1991 Walch then Jobe developed the concept of posterosuperior impingement to explain lesions observed arthroscopically. This impingement between the deep aspect of the supraspinatus tendon and the glenoid occurs during loaded arm movements. The purpose of this work was to study the different types of lesions observed arthroscopically and to analyse outcome after arthroscopic debridement. Our series included 75 thrower athletes who had shoulder pain for loaded arm movements. Pain was situated in the dominant shoulder in all cases. Clinically, the Jobe manipulation provoked pain in 52 patents, expression of a supraspinous disorder. After failure of conservative treatment, the patients underwent arthroscopy for assessment and debridement. At the time of arthroscopy, the patients had suffered pain for two years (mean 22.3 months). All 75 patients were seen for clinical and radiological assessment at least two years after arthroscopy. Among the 75 arthroscopies, there were 67 (89%) partial tears involving the deep aspect of the cuff, associated in 90% of the cases with a labral lesion. Tears involved the supraspinatus in 40 cases, the supraspinatus and the infraspinatus in 24 and the infraspinatus alone in three. Eight patients were free of tendon lesions at arthroscopy. There were no full thickness tears. The labrum had a meniscal (45%) or non-meniscal aspect (55%) and appeared normal (18%), fringed (38%) or fissured (52%). The very large majority of the labral fissures were found behind the biceps insertion. Fissures of the labrum were found in front of the biceps insertion in only three cases (slap lesion). Arthroscopy demonstrated glenoid damage (soft cartilage, fissure, abrasion, wear). The humeral head also exhibited lesions of the cartilage facing the insertion of the infraspinatus. At last follow-up (minimum > 2 years), eight patients were very satisfied, 22 were satisfied and 45 were disappointed. Twelve patients had resumed their sports activities at their former level with loaded arm movement and one patient had interrupted all sports activities. At last follow-up, 22 patient had undergone another surgical procedure: 20 derotation osteotomies of the humerus, one anterior stabilization, one acromioplasty. The notion of posterosuperior impingement is increasingly recognized as the cause of pain in thrower athletes. Loaded arm movements produce a physiological contact between the posteriorsuperior edge of the glenoid cavity and the deep aspect of the rotator cuff. Injury results from repeated loaded arm movements in throwers. In our series, all the patients had at least one lesion, either involving the cuff or the labrum. According to the Snyder classification, 80% of the supraspinatus lesions were grade 1 or grade 2. We did not have any full thickness tears. All patients with a normal cuff were found to have a lesion of the posterosuperior labrum. At arthroscopy, dynamic assessment evidenced an impingement between the supraspinatus (or the infraspinatus) and the labrum or the bony edge of the glenoid cavity. Only three patients had a labral lesion anterior to the biceps insertion that could be considered a type 1 or 2 slap lesion. Unlike earlier reports by others, we had disappointing results after debridement: 60% of the patients were disappointed after the procedure and only 40% were satisfied (22 patients) or very satisfied (8 patients). Patient satisfaction depended greatly on the level of sports activity attained after arthroscopy, the eight very satisfied patients had resumed their former level. None of the professional athletes or those competing at the international level were very satisfied with arthroscopic debridement. There was an inverse relationship between level of competition and patient satisfaction after debridement.

Anterior debridement/bone grafting/posterior instrumentation is a common selection for the treatment of lumbar spinal tuberculosis (LST). To date, no study has focused on the prognostic factors for recovery after this surgery. We included 144 patients who experienced anterior debridement/bone grafting/posterior instrumentation for LST. The recovery rate based on the Japanese Orthopedic Association (JOA) score was used to assess recovery. The Kaplan-Meier method and Cox regression analysis were used to identify the prognostic factors for recovery postoperatively. For the prognostic factors worth further consideration, the changes in JOA scores within the 24-month follow-up period were identified by repeated-measures analysis of variance. Paralysis/nonparalysis, duration of symptoms (≥3/<3 months), number of involved vertebrae (>2/≤2), and posterior open/percutaneous instrumentation were identified as prognostic factors for recovery postoperatively. The prognostic factor of open/percutaneous instrumentation was then further compared for potential clinical application. Patients in the percutaneous instrumentation group achieved higher JOA scores than those in the open instrumentation group in the early stages postoperatively (1-3 months), but this effect equalized at 6 months postoperatively. Patients in the open instrumentation group experienced longer operation time and less cost than those in the percutaneous instrumentation group. Nonparalysis, shorter symptom duration, fewer involved vertebrae, and posterior percutaneous instrumentation (compared with open instrumentation) are considered favorable prognostic factors. Patients in the percutaneous instrumentation group achieved higher JOA scores than those in the open instrumentation group in the early stages postoperatively (1-3 months), but no significant difference was observed in long-term JOA scores (6-24 months).

An in vitro model for peri-implantitis treatment was used to identify areas that are clinically difficult to clean by analyzing the pattern of residual stain after debridement with commonly employed instruments. Original data from two previous publications, which simulated surgical (SA) and non-surgical (NSA) implant debridement on two different implant systems respectively, were reanalyzed regarding the localization pattern of residual stains after instrumentation. Two blinded examiners evaluated standardized photographs of 360 initially ink-stained dental implants, which were cleaned at variable defect angulations (30, 60, or 90°), using different instrument types (Gracey curette, ultrasonic scaler or air powder abrasive device) and treatment approaches (SA or NSA). Predefined implant surface areas were graded for residual stain using scores ranging from one (stain-covered) to six (clean). Score differences between respective implant areas were tested for significance by pairwise comparisons using Wilcoxon-rank-sum-tests with a significance level α = 5%. Best scores were found at the machined surface areas (SA: 5.58 ± 0.43, NSA: 4.76 ± 1.09), followed by the tips of the threads (SA: 4.29 ± 0.44, NSA: 4.43 ± 0.61), and areas between threads (SA: 3.79 ± 0.89, NSA: 2.42 ± 1.11). Apically facing threads were most difficult to clean (SA: 1.70 ± 0.92, NSA: 2.42 ± 1.11). Here, air powder abrasives provided the best results. Machined surfaces at the implant shoulder were well accessible and showed least amounts of residual stain. Apically facing thread surfaces constituted the area with most residual stain regardless of treatment approach.

The aim of this study was to evaluate the clinical outcomes of a concept for non-surgical peri-implantitis combining stepwise mechanical debridement measures with adjuvant Povidone-iodine application with and without systemic antibiotics. 45 patients with chronic periodontitis comprising 164 screw-typed implants with peri-implantitis were included. Peri-implantitis was defined as radiographic bone loss of >2 mm, probing pocket depth (PD) ≥5 mm with bleeding on probing (BOP). Stepwise treatment of implants was performed with ultrasonic debridement, soft tissue curettage (STC), glycine powder air polishing (GPAP) and a repeated submucosal application of Povidone-iodine. Teeth with PD >4mm were treated simultaneously according to the same concept except STC. In cases with severe periodontitis (N = 24), amoxicillin and metronidazole (AM) were prescribed for 7 days. After 12 months, implants treated without AM showed significant reductions (p<0.05) of mean PD (1.4 ± 0.7 mm), CAL (1.3 ± 0.8 mm) and BOP (33.4 ± 17.2%). In deep pockets (PD >6mm) changes of mean PD (2.3 ± 1.3 mm), CAL (2.0 ± 1.6 mm) and BOP (44.0 ± 41.7%) were more pronounced. Intake of AM did not significantly influence the changes of these parameters. However, the reduction of implant sites with PD >4 mm and BOP was significantly higher in patients with AM than in those without AM (31.8 ± 12.6% vs. 20.8 ± 14.7%; p<0.05). The combination of ultrasonic debridement, STC and GPAP with adjuvant Povidone-iodine led to significant clinical improvements at implants. Systemic antibiotics had limited effects on the reduction of persisting implant sites with treatment need.

Rehabilitation and return-to-sports activity after debridement and bone marrow stimulation of osteochondral talar defects.

An osteochondral defect (OD) is a lesion involving the articular cartilage and the underlying subchondral bone. ODs of the talus can severely impact on the quality of life of patients, who are usually young and athletic. The primary treatment for ODs that are too small for fixation, consists of arthroscopic debridement and bone marrow stimulation. This article delineates levels of activity, determines times for return to activity and reviews the factors that affect rehabilitation after arthroscopic debridement and bone marrow stimulation of a talar OD. Articles for review were obtained from a search of the MEDLINE database up to January 2012 using the search headings 'osteochondral defects', 'bone marrow stimulation', 'sports/activity', 'rehabilitation', various other related factors and 'talus'. English-, Dutch- and German-language studies were evaluated.The review revealed that there is no consensus in the existing literature about rehabilitation times or return-to-sports activity times, after treatment with bone marrow stimulation of ODs in the talus. Furthermore, scant research has been conducted on these issues. The literature also showed that potential factors that aid rehabilitation could include youth, lower body mass index, smaller OD size, mobilization and treatment with growth factors, platelet-rich plasma, biphosphonates, hyaluronic acid and pulse electromagnetic fields. However, most studies have been conducted in vitro or on animals. We propose a scheme, whereby return-to-sports activity is divided into four phases of increasing intensity: walking, jogging, return to non-contact sports (running without swerving) and return to contact sports (running with swerving and collision). We also recommend that research, conducted on actual sportsmen, of recovery times after treatment of talar ODs is warranted.

Objective: Compare enzymatic debridement using clostridial collagenase ointment (CCO) with autolytic debridement using medicinal honey in the hospital outpatient setting for treating pressure ulcers (PUs). Approach: Retrospective deidentified electronic health records from 2007–2013 were extracted from the U.S. Wound Registry. Propensity score matching followed by multivariable analyses was used to adjust for selection bias and assess treatment effects comparing CCO-treated versus honey-treated PUs. Key outcomes included 100% granulation and epithelialization at 1 year. Results: Five hundred seventeen CCO-treated PUs (446 patients) were matched to corresponding honey-treated PUs (341 patients). The majority of PUs were stage III (CCO 56%, honey 55%). CCO users had significantly fewer total visits (9.1 vs. 12.6; p < 0.001), fewer total selective sharp debridements (2.7 vs. 4.4; p < 0.001), and fewer PUs receiving negative pressure wound therapy (29% vs. 38%; p = 0.002) compared with honey. Innovation: CCO-treated PUs were 38% more likely to achieve 100% granulation compared to honey-treated PUs at 1 year, p = 0.018. Mean days to 100% granulation were significantly lower for CCO-treated PUs (255 vs. 282 days, p < 0.001). CCO-treated PUs were 47% (p = 0.024) more likely to epithelialize at 1 year compared to PUs treated with honey. Mean days to epithelialization were significantly lower for PUs treated with CCO at 1 year (288 vs. 308 days; p = 0.011). Conclusion: All stages of PUs treated with CCO achieved faster rates of granulation and subsequent epithelialization compared to PUs treated with medicinal honey as measured by real-world data collected in the hospital outpatient department care setting.

There are no prospective endodontic studies to determine the outcome of an incision and drainage (I&D) procedure for swelling in healthy, endodontic patients. The purpose of this prospective, randomized, single-blind study was to compare the postoperative course of I&D with drain placement versus a mock I&D procedure with mock drain placement after endodontic debridement in swollen emergency patients with symptomatic teeth and a pulpal diagnosis of necrosis. Eighty-one adult emergency patients presenting with clinical swelling received either penicillin or, if allergic, clindamycin and complete endodontic debridement, and then were randomly divided into 2 treatment groups: I&D with drain placement or a mock I&D procedure with mock drain placement. At the end of the appointment, all patients received a combination of ibuprofen/acetaminophen and, if needed, an opioid-containing escape medication. Patients recorded their pain and medication use for 4 days postoperatively. Success was defined as no or mild postoperative pain and no use of an opioid-containing escape medication. Success was evaluated using repeated measure mixed model logistic regression. Both groups had a decrease in postoperative pain and medication use over the 4 days. The mock I&D group had significantly higher success than the I&D group (odds ratio = 2.00; 95% confidence interval, 1.16-3.41). The success rate was 45% with the mock I&D and 33% with the I&D. After endodontic debridement, patients who received a mock I&D procedure with mock drain placement had more success than patients who received I&D with drain placement. Both groups clinically improved over 4 days. Copyright © 2017 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

Ubiquitous fungi of the Scedosporium apiospermum species complex (SASC) cause various opportunistic infections. Posterior subtenon triamcinolone acetonide (STTA) injection is a standard therapy for intraocular inflammation and macular edema. We report a case of Scedosporium apiospermum infectious scleritis after a posterior STTA injection. A 75-year-old man received a posterior STTA injection to treat macular edema in his left eye. After 3 months, he complained of ocular pain and hyperemia in his left eye. Examination showed a subtenon abscess in the site corresponding with the STTA injection. After incising the abscess, the smear revealed numerous conidia-like structures. Although we suspected fungal infection and started topical voriconazole (VRCZ) and levofloxacin, the inflammation of the eye worsened. Fungal culture revealed filamentous fungus growth. Subsequently, we added systemic VRCZ and performed surgical debridement of the infected sclera and Tenon's capsule. Pathology of the sclera showed fungal hyphae. The antifungal susceptibility test revealed low minimum inhibitory concentrations for micafungin, VRCZ and miconazole (0.06, 0.25 and 0.5 μg/mL, respectively). After 2 months, the ciliary injection subsided and VRCZ therapy was stopped. However, subtenon abscess recurred 1 month after discontinuation of topical VRCZ. Surgical debridement and topical VRCZ were resumed, with the eye finally improving after 5 months of management. The fungal species was identified as Scedosporium apiospermum sensu stricto morphologically and by DNA sequencing. This case was successfully treated by topical and systemic VRCZ and repeated surgical debridement. Infectious scleritis caused by SASC rarely develops after posterior STTA. SASC can produce conidia in the enclosed subtenon space. Late-onset infectious scleritis after a posterior STTA injection suggests the presence of a fungal infection, including SASC, thereby requiring extensive and prolonged medical and surgical treatment.

This is the first controlled study to explore whether adjunctive immersive virtual reality (VR) can reduce excessive pain of soldiers with combat-related burn injuries during wound debridement. Patients were US soldiers burned in combat attacks involving explosive devices in Iraq or Afghanistan. During the same wound care session using a within-subject experimental design, 12 patients received half of their severe burn wound cleaning procedure (~6 minutes) with standard of care pharmacologies and half while in VR (treatment order randomized). Three 0 to 10 Graphic Rating Scale pain scores for each of the treatment conditions served as the primary variables. Patients reported significantly less pain when distracted with VR. "Worst pain" (pain intensity) dropped from 6.25 of 10 to 4.50 of 10. "Pain unpleasantness" ratings dropped from "moderate" (6.25 of 10) to "mild" (2.83 of 10). "Time spent thinking about pain" dropped from 76% during no VR to 22% during VR. Patients rated "no VR" as "no fun at all" (<1 of 10) and rated VR as "pretty fun" (7.5 of 10). Follow-up analyses showed VR was especially effective for the six patients who scored 7 of 10 or higher (severe to excruciating) on the "worst pain" (pain intensity) ratings. These preliminary results provide the first evidence from a controlled study that adjunctive immersive VR reduced pain of patients with combat-related burn injuries during severe burn wound debridement. Pain reduction during VR was greatest in patients with the highest pain during no VR. These patients were the first to use a unique custom robot-like arm mounted VR goggle system.

The present study describes a new temporary arthrodesis procedure, which aims for septic knee prosthesis replacement, in particular for larger bone and soft tissue defects. Our technique offers high stability and full weight-bearing capacity of the knee joint. The study included 16 patients with major bone defects (AORI type IIb or greater) after receiving a radical debridement and a septic two-stage revision total knee arthroplasty. After removing the infected prosthesis and debridement, two AO fixator rods were positioned into the intramedullary space of the femur and tibia. Subsequently, both rods were joined tube-to-tube and adjusted in the center of the knee joint. Finally, the whole cavity of the knee joint was filled with PMMA. The number of previous surgeries, bacterial spectrum, risk factors for further infection and reinfection rates was recorded. Immediately after the temporary arthrodesis, radiographs of the knee with the enclosed spacers were taken in order to compare to previous radiographs and avoiding to miss possible spacer loosening. Nine of sixteen patients underwent more than two revision surgeries before receiving our new arthrodesis technique. No cases of spacer loosening were observed in all 16 patients; further, there were no peri-implant fractures, and four persistent infections were noted. Temporary arthrodesis using AO fixator rods offers a high stability without loosening. Its potential to replace conventional augmentation techniques should be taken into account, particularly in the case of larger bone and tissue defects. In clinical practice, the cemented spacer using AO fixator rods could be an alternative technique for temporary knee arthrodesis after septic debridement. Retrospective case series, Level IV.

To evaluate the causes, treatment and prevention of esophageal fistulas after anterior cervical spine surgery. Between January 2004 and December 2011, 5 of 2348 patients who underwent anterior cervical surgery in our hospital developed esophageal fistulas (three male and two female patients, average age 34 years). Their diagnoses were cervical injuries (three), cervical spondylosis (one) and cervical tuberculosis (one). Their esophageal fistulas were treated by debridement and exploratory surgery, primary suturing of the perforation and/or sternocleidomastoid myoplasty. If conservative treatment failed or esophageal fistula recurred, plate removal was offered. Postoperative treatment included esophageal rest, enteral nutrition, wound drainage, and antibiotics. Methylene blue was used to evaluate results. An esophageal fistula was discovered during anterior cervical surgery in one patient and primary suturing performed. In four patients, fistulas were diagnosed after anterior cervical decompression and fusion. In one of these, only debridement and exploratory surgery were required. In another, a perforation was sutured during debridement and exploratory surgery. In the third, internal fixation was removed because of failure of prolonged conservative treatment. In the fourth, the esophageal fistula recurred repeatedly; he required removal of the hardware and reinforcement with a sternocleidomastoid muscle flap. At 6-48 months follow-up, all patients were in good condition, symptom free, and without cervical instability or infectious spondylitis. Successful management of esophageal fistula after anterior cervical spinal surgery depends on primary closure of the perforation with or without muscle flaps, surgical drainage, esophageal rest and nutritional support, and removal of hardware if necessary. Prevention consists of careful surgery and gentle tissue handling. © 2012 Tianjin Hospital and Wiley Publishing Asia Pty Ltd.

The purpose of this study was to assess the level of air contamination with bacteria after surgical hydrodebridement and to determine the effectiveness of hydro surgery on bacterial reduction of a simulated infected wound. Four porcine samples were scored then infected with a broth culture containing a variety of organisms and incubated at 37 degrees C for 24 hours. The infected samples were then debrided with the hydro surgery tool (Versajet, Smith and Nephew, Largo, Florida, USA). Samples were taken for microbiology, histology and scanning electron microscopy pre-infection, post infection and post debridement. Air bacterial contamination was evaluated before, during and after debridement by using active and passive methods; for active sampling the SAS-Super 90 air sampler was used, for passive sampling settle plates were located at set distances around the clinic room. There was no statistically significant reduction in bacterial contamination of the porcine samples post hydrodebridement. Analysis of the passive sampling showed a significant (p < 0.001) increase in microbial counts post hydrodebridement. Levels ranging from 950 colony forming units per meter cubed (CFUs/m3) to 16780 CFUs/m3 were observed with active sampling of the air whilst using hydro surgery equipment compared with a basal count of 582 CFUs/m3. During removal of the wound dressing, a significant increase was observed relative to basal counts (p < 0.05). Microbial load of the air samples was still significantly raised 1 hour post-therapy. The results suggest a significant increase in bacterial air contamination both by active sampling and passive sampling. We believe that action might be taken to mitigate fallout in the settings in which this technique is used.

To determine the impact of the loss of syndecan 1 (SDC1) on intraepithelial corneal nerves (ICNs) during homeostasis, aging, and in response to 1.5-mm trephine and debridement injury. Whole-mount corneas are used to quantify ICN density and thickness over time after birth and in response to injury in SDC1-null and wild-type (WT) mice. High-resolution three-dimensional imaging is used to visualize intraepithelial nerve terminals (INTs), axon fragments, and lysosomes in corneal epithelial cells using antibodies against growth associated protein 43 (GAP43), βIII tubulin, and LAMP1. Quantitative PCR was performed to quantify expression of SDC1, SDC2, SDC3, and SDC4 in corneal epithelial mRNA. Phagocytosis was assessed by quantifying internalization of fluorescently labeled 1-μm latex beads. Intraepithelial corneal nerves innervate the corneas of SDC1-null mice more slowly. At 8 weeks, ICN density is less but thickness is greater. Apically projecting intraepithelial nerve terminals and lysosome-associated membrane glycoprotein 1 (LAMP1) are also reduced in unwounded SDC1-null corneas. Quantitative PCR and immunofluorescence studies show that SDC3 expression and localization are increased in SDC1-null ICNs. Wild-type and SDC1-null corneas lose ICN density and thickness as they age. Recovery of axon density and thickness after trephine but not debridement wounds is slower in SDC1-null corneas compared with WT. Experiments assessing phagocytosis show reduced bead internalization by SDC1-null epithelial cells. Syndecan-1 deficiency alters ICN morphology and homeostasis during aging, reduces epithelial phagocytosis, and impairs reinnervation after trephine but not debridement injury. These data provide insight into the mechanisms used by sensory nerves to reinnervate after injury.

How often do surgeons intervene on shoulder labral lesions detected at MR examination? A retrospective review of MR examinations correlated with arthroscopy

PubMed Central

2014-01-01

Objective: We report the prevalence of surgical intervention on shoulder labral lesions detected at MR examinations and how surgeons describe labral tears seen at MR examinations in their arthroscopy reports. Methods: A retrospective review of 100 consecutive patients aged 50 years or younger who had shoulder labral tears on MR and went on to have surgery performed. It was determined whether surgical intervention was performed on the MR lesions. Results: Of these 100 patients, 72 had superior labral anterior to posterior (SLAP) tears, 38 had posterior labral tears and 28 had anterior labral tears on MR examination. All 100 patients went on to arthroscopy. All lesions described on MRI were described on arthroscopy. Of the 72 SLAP tears, 64 were described as fraying on arthroscopy with 51 debrided. The remaining eight SLAP tears were tacked surgically. Of the 38 posterior labral tears, 36 were described as fraying on arthroscopy with 29 debrided and 2 had surgical tacking performed. Of the 28 anterior labral tears described on MR examination, 26 had surgical tacking performed and 2 were debrided. There were four SLAP tears, two anterior labral tears and three posterior labral tears seen on arthroscopy but not seen on MR examination. Conclusion: In this series, a high percentage of SLAP tears and posterior labral tears described on MR examination did not have surgical tacking. Most anterior labral tears had surgical tacking. Based on the above, our surgeons request we describe superior and posterior labral lesions as fraying and/or tearing, unless we can see a displaced tear. Most anterior labral lesions are treated with surgical tacking. Advances in knowledge: MRI allows for sensitive detection of labral tears. The tears often are not clinically significant.

In this study, we investigated the wound-healing process after photorefractive keratectomy with mitomycin C (MMC) in hen corneas. In addition, we evaluated the synergistic effect of ethanol and MMC. Forty-eight adult hens were divided into 3 groups: A: ethanol-assisted debridement plus MMC; B: mechanical debridement plus MMC; and C: mechanical debridement (MMC-untreated control). Photorefractive keratectomy was performed, and the animals were followed up for up to 60 days. Epithelial healing was measured with fluorescein. Apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick end-labeling assay and proliferation was measured by BrdU incorporation. Both myofibroblast differentiation and collagen deposition were evaluated by immunofluorescence and histology. Epithelial wound closure was similar in all 3 groups (P > 0.05). Significant reduction in haze was observed in groups A and B compared with C (P < 0.01), but there was no difference between groups A and B (P > 0.05). Furthermore, there was no difference in the number of apoptotic cells between groups. Proliferation was delayed in both groups A and B compared with C (P < 0.01), but groups A and B did not differ significantly (P > 0.05). Myofibroblasts, cellular density, and collagen deposition were lower in both groups A and B compared with C (P < 0.01), but they were not significantly different from each other (P > 0.05). Topical application of MMC in hen corneas reproduces the wound healing observed in humans by reducing haze, keratocyte proliferation, myofibroblast differentiation, and new collagen deposition. Synergistic cytotoxic effects of ethanol and MMC were not observed.

To assess the effects of nonsteroidal antiinflammatory drug (NSAID) eyedrops on the expression of matrix metalloproteinases in corneal tissue. Ocular Microbiology and Immunology Laboratory, Refractive Surgery Research Laboratory, The Wilmer Eye Institute, Johns Hopkins University, Baltimore, Maryland, USA. Seventy rats were divided into 2 groups: intact and debrided epithelium. Uniform central corneal epithelial defects were created in the right eye of the debrided corneal group. Each group was divided into 4 subgroups, each receiving 1 of the following eyedrops or artificial tears: The 3 NSAIDs were diclofenac sodium 0.1% (Falcon or Voltaren) and preservative-free ketorolac 0.5% (Acular PF). The artificial tears were carboxymethylcellulose sodium 0.5% (Refresh Plus PF). The eyedrops were administered 4 times a day for 1 week. The rats were killed on days 2 and 7. The corneas were excised and processed for immunohistochemical staining, Western blot assay, and zymography studies to determine the localization of the production of the following matrix metalloproteinases (MMPs): MMP-1, MMP-2, MMP-8, and MMP-9. Matrix metalloproteinase-1, MMP-8, and MMP-2 were detected in rat corneas at 48 hours in the debrided and intact epithelium groups treated with NSAID eyedrops. The MMP-1 and MMP-8 expression levels were higher in intact corneas in the diclofenac sodium groups than in the ketorolac and artificial tears groups. The expression was localized mostly in the epithelial cells and occasionally in keratocytes. This study provides preliminary evidence that topical application of some NSAIDs can induce the early expression of MMP-1, MMP-2, and MMP-8 in the cornea, suggesting that MMPs play a role in the corneal cytotoxicity of certain NSAIDs.

Sweet's syndrome mimicking alkali burn: a clinical conundrum.

2013-06-01

Sweet's syndrome or acute febrile neutrophilic dermatosis presents most commonly on the hands, upper extremities and face. The disease is of clinical relevance to surgeons as it could mimic an infective aetiology but debridement negates such wounds. A 34-year-old man was referred from a peripheral hospital with suspected infected alkali burn to the hands. A builder by profession, he had been working outdoors with possible exposure to cement-concrete mix, 5 days previously. At presentation, the dorsal aspect of the thenar eminence appeared erythematous and oedematous, with pustules and blisters with central ulcerations. Haematological investigation revealed a neutrophilic leucocytosis and raised CRP. On the second day of admission the patient became febrile. He was treated with analgesia, IV Tazocin (Pipperacillin and Tazobactam) and the wounds were surgically debrided and covered using autologous cell therapy via the Recell kit. Two days following surgery, microbiology of wound swabs, tissue samples and blood cultures yielded no growth. The wound was noted to be extending beyond the zone of injury and a new area of erythema was evident on the neck. A diagnosis of idiopathic acral Sweet's syndrome was confirmed when histopathological investigation showed a moderate inflammatory cell infiltrate in the dermis. A rapid response to oral corticosteroids was clinically evident after 48 h and the lesions were completely healed at 4 weeks follow-up. We recommend thorough clinical history and examination, systematic wound review, tissue biopsy and culture in conjunction with dermatology opinion in cases of suspected Sweet's syndrome. Surgical debridement should be avoided as it has the potential to negate such wounds secondary to pathergy phenomenon.

Safety of achilles detachment and reattachment using a standard midline approach to insertional enthesophytes.

McAlister, Jeffrey E; Hyer, Christopher F

2015-01-01

Detachment with reattachment of the Achilles tendon is a common surgery for debridement of retrocalcaneal exostosis, bursitis, and other insertional pathologic entities. The technique involves a midline skin incision on the posterior Achilles to the tendon. The distal Achilles attachment is removed in a U-shaped manner, leaving the medial and lateral flares, but exposing the posterior spur. This midline approach provides excellent exposure and allows for rapid and efficient surgical debridement. The tendon is reapproximated and repaired with a suture anchor to facilitate fixation to the posterior calcaneus. Some surgeons have expressed concerned that the rupture risk could be increased in the postoperative period using this technique. The present study was a retrospective medical record review of 98 patients (100 feet) who had undergone a midline approach with Achilles reattachment after insertional Achilles debridement during a 3-year period. The demographic and comorbidity data were collected and analyzed. The outcome measures were postoperative rupture and the need for revision surgery. The mean age was 51.9 years, and the patients included 59 females (60.2%) and 39 males (39.8%). The complications included 4 rupture or avulsion revisions (4.0%) and 2 recurrent pain and tendinitis revisions (2.0%). The most common repeat repair procedure included hardware removal and a flexor hallucis longus transfer or augmentation. Nine patients (9.0%) had wound complications, 7 (77.8%) of which necessitated incision and drainage. The midline approach with Achilles detachment and reattachment is a safe and effective method of surgical treatment of insertional Achilles pathologic entities. The low reoperation rate of 4.0% will allow foot and ankle surgeons to safely rely on this approach. Copyright © 2015 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

In a previous study, we proposed a new therapy using topical bromelain as a supplement to simple wound-track incision for the debridement of firearm wounds. This enzymatic debridement greatly simplified the management of high-velocity gunshot wounds in a pig model, and bromelain was confirmed to improve wound healing. The purpose of the present study was to investigate the effect of bromelain on the microenvironment of firearm wounds. Sixteen Chinese landrace pigs wounded by high-velocity projectiles were divided randomly into four groups: wound incision (group I), incision + bromelain (group IB), wound excision (group E), and control. Blood perfusion, oxygen partial pressure (pO(2)), and the content of tumor necrosis factor (TNF)-α and transforming growth factor (TGF)-β in wound-track tissue were measured. Wound healing was also noted. The recovery of blood perfusion in tissue and pO(2) in wound tracks was significantly more rapid in group IB and group E than in group I and control. The tissue level of TNF-α was significantly lower in group IB than in group I and control 48 h and 72 h post-wounding, and was lower than in group E 48 h post-wounding. The tissue level of TGF-β in group IB was sustained at a significantly higher level than in the other three groups. Wound healing time was also shorter in group IB. Enzymatic debridement using topical bromelain in incised wound tracks accelerates the recovery of blood perfusion, pO(2) in wound tissue, controls the expression of TNF-α and raises the expression of TGF-β.

Background This is the first controlled study to explore whether adjunctive immersive virtual reality (VR) can reduce excessive pain of soldiers with combat-related burn injuries during wound debridement. Methods Patients were US soldiers burned in combat attacks involving explosive devices in Iraq or Afghanistan. During the same wound care session using a within-subject experimental design, 12 patients received half of their severe burn wound cleaning procedure (∼6 minutes) with standard of care pharmacologies and half while in VR (treatment order randomized). Three 0 to 10 Graphic Rating Scale pain scores for each of the treatment conditions served as the primary variables. Results Patients reported significantly less pain when distracted with VR. “Worst pain” (pain intensity) dropped from 6.25 of 10 to 4.50 of 10. “Pain unpleasantness” ratings dropped from “moderate” (6.25 of 10) to “mild” (2.83 of 10). “Time spent thinking about pain” dropped from 76% during no VR to 22% during VR. Patients rated “no VR” as “no fun at all” (<1 of 10) and rated VR as “pretty fun” (7.5 of 10). Follow-up analyses showed VR was especially effective for the six patients who scored 7 of 10 or higher (severe to excruciating) on the “worst pain” (pain intensity) ratings. Conclusions These preliminary results provide the first evidence from a controlled study that adjunctive immersive VR reduced pain of patients with combat-related burn injuries during severe burn wound debridement. Pain reduction during VR was greatest in patients with the highest pain during no VR. These patients were the first to use a unique custom robot-like arm mounted VR goggle system. PMID:21795888

Debridement, antibiotics, and implant retention (DAIR) is a widely used treatment modality for early acute prosthetic joint infection (PJI). A preoperative risk score was previously designed for predicting DAIR failure, consisting of chronic renal failure (K), liver cirrhosis (L), index surgery (I), cemented prosthesis (C), and C-reactive protein >115 mg/L (KLIC). The aim of this study was to validate the KLIC score in an external cohort. We retrospectively evaluated patients with early acute PJI treated with DAIR between 2006 and 2016 in 3 Dutch hospitals. Early acute PJI was defined as <21 days of symptoms and DAIR performed within 90 days after index surgery. Failure was defined as the need for (1) second DAIR, (2) implant removal, (3) suppressive antimicrobial treatment, or (4) infection-related death within 60 days after debridement. A total of 386 patients were included. Failure occurred in 148 patients (38.3%). Patients with KLIC scores of ≤2, 2.5-3.5, 4-5, 5.5-6.5, and ≥7 had failure rates of 27.9%, 37.1%, 49.3%, 54.5%, and 85.7%, respectively (P < .001). The receiver-operating characteristic curve showed an area under the curve of 0.64 (95% confidence interval 0.59-0.69). A KLIC score higher than 6 points showed a specificity of 97.9%. The KLIC score is a relatively good preoperative risk score for DAIR failure in patients with early acute PJI and appears to be most useful in clinical practice for patients with low or high KLIC scores.

Prosthetic joint infection remains one of the most devastating complications of arthroplasty. Debridement and retention of the prosthesis is an attractive management option in carefully selected patients. Despite this, there are no data investigating the cost of this management modality for prosthetic joint infections. The aim of this case-control study was to calculate the cost associated with debridement and retention for management of prosthetic joint infection compared with primary joint replacement surgery without prosthetic joint infection. From 1 January 2008 to 30 June 2010, there were 21 prosthetic joint infections matched to 42 control patients. Controls were matched to cases according to the arthroplasty site, age and sex. Cases had a greater number of unplanned readmissions (100% vs. 7.1%; p <0.001), more additional surgery (3.3 vs. 0.07; p <0.001) and longer total bed days (31.6 vs. 7.9 days; p <0.001). In addition they had more inpatient, outpatient and emergency department visits (p <0.001, respectively). For patients with prosthetic joint infection the total cost, including index operation and costs of management of the prosthetic joint infection, was 3.1 times the cost of primary arthoplasty; the mean cost for cases was Australian dollars (AUD) $69,414 (±29,869) compared with $22,085 (±8147) (p <0.001). The demand for arthroplasty continues to grow and with that, the number of prosthetic joint infections will also increase, placing significant burden on the health system. Our study adds significantly to the growing body of evidence highlighting the substantial costs associated with prosthetic joint infection. © 2011 The Authors.

Candida albicans vertebral osteomyelitis is rare. Three cases are presented. Without antifungal treatment, they developed spinal collapse and neurological deterioration within 3-6 months from the onset of symptoms. There was a delay of 4.5 and 7.5 months between the onset of symptoms and surgery. All patients were managed with surgical debridement and reconstruction and 12-week fluconazole treatment. The neurological deficits resolved completely. The infection has not recurred clinically or radiologically at 5-6 years follow-up. Although rare, Candida should be suspected as a causative pathogen in cases of spinal osteomyelitis. Without treatment the disease is progressive. As soon as osteomyelitis is suspected, investigations with MRI and percutaneous biopsy should be performed followed by medical therapy. This may prevent the need for surgery. However, if vertebral collapse and spinal cord compression occurs, surgical debridement, fusion and stabilisation combined with antifungal medications can successfully eradicate the infection and resolve the neurological deficits.

Candida albicans vertebral osteomyelitis is rare. Three cases are presented. Without antifungal treatment, they developed spinal collapse and neurological deterioration within 3–6 months from the onset of symptoms. There was a delay of 4.5 and 7.5 months between the onset of symptoms and surgery. All patients were managed with surgical debridement and reconstruction and 12-week fluconazole treatment. The neurological deficits resolved completely. The infection has not recurred clinically or radiologically at 5–6 years follow-up. Although rare, Candida should be suspected as a causative pathogen in cases of spinal osteomyelitis. Without treatment the disease is progressive.

2015-01-01

Periodontal diseases are infectious diseases with a mixed microbial aetiology and marked inflammatory response leading to destruction of underlying tissue. Periodontal therapy aims to eliminate pathogens associated with the disease and attain periodontal health. Periodontitis is generally treated by nonsurgical mechanical debridement and regular periodontal maintenance care. Periodontal surgery may be indicated for some patients to improve access to the root surface; however, mechanical debridement alone may not be helpful in all cases. In such cases, adjunctive systemic antibiotic therapy remains the treatment of choice. It can reach microorganisms at the base of the deep periodontal pockets and furcation areas via serum, and also affects organisms residing within gingival epithelium and connective tissue. This review aims to provide an update on clinical issues regarding when and how to prescribe systemic antibiotics in periodontal therapy. The points discussed are the mode of antibiotic action, susceptible periodontal pathogens, antibiotic dosage, antibiotic use in treatment of periodontal disease, and mechanism of bacterial resistance to each antibiotic.

Necrotizing fasciitis: microbiological characteristics and predictors of postoperative outcome

PubMed Central

2009-01-01

Objective Necrotizing fasciitis is a life threatening soft-tissue infection with a high morbidity and mortality. Prompt treatment based on extensive surgical debridement and antibiotic therapies are the therapeutic principles. Methods The medical records of patients with necrotizing fasciitis (n = 26) from 1996 to 2005 were retrospectively analyzed. Results The localization of necrotizing fasciitis was most commonly the trunk (42.3%). Type I polymicrobial infection was the dominating infection. The involvement of anaerobic bacteria was associated with an increase in the number of surgical revisions (p = 0.005). Length of postoperative intensive care unit stay, duration of postoperative ventilation and mortality were significantly increased in the ASA IV-V group. Computed tomography displayed only a limited significance as diagnostic tool for initial diagnosis. Conclusions In severe cases the combination of necrotic skin and soft tissue gas facilitates the correct diagnosis, which should than be followed by immediate - and most often - repeated debridement. If anaerobes are isolated an early and aggressive second look is necessary. PMID:19258208

The apical delta is an intricate system within the root canal and incompletely debridement may affect the long-term prognosis of root canal therapy. The aim of the present study is to investigate the morphologic features of apical deltas in human teeth with micro-computed tomography (micro-CT) using a centreline-fitting algorithm. One hundred and thirty-six apical deltas were detected in 1400 teeth. Molars had more apical deltas (15.8%) than anterior teeth (6.3%). In maxillary molars, the mesiobuccal root had a significantly higher prevalence of apical delta than the palatal root or the distobuccal root. The median vertical distance of the apical delta was 1.87 mm with 13% more than 3 mm. The median diameter and length of the apical delta branches were 132.3 and 934.5 μm. Apical delta branches were not straight with cross-sectional shapes being non-circular. These morphological features of apical delta may complicate debridement of the infected root canal system.

Necrotizing fasciitis (NF) is a fatal and rare disease, mainly located in extremity and body. Due to the good blood supply, the occurrence of this infective disease of skin and subcutaneous tissue/fascia is much rarer in the head and neck region. In this study, we represent periorbital necrotizing fasciitis case in a patient with normal immune system. The patient applied the emergency clinic with the complaints of swelling and redness on the left eye. It was found out that a skin incision occurred at 2 cm below the left eye with razor blade 2 days ago. After taking swab culture sample, patient was started on parenteral Vancomycin + Ampicillin-Sulbactam treatment. It was observed that necrosis spread within hours and an emergent deep surgical debridement was performed. Following the debridement, it was observed that periorbital edema began to regress prominently on the 1st day of the treatment. Treatment was carried on with daily wound care and parenteral antibiotherapy. The patient was discharged from the hospital with slightly cosmetic defect. PMID:25309766

Current guidelines recommend a multidisciplinary systematic integrated approach to patient with chronic cough in which nowadays otolaryngologists play an increasingly valuable role as new procedures are used for evaluation and treatment. Surgery has been never taken into consideration to treat refractory chronic cough. We present a rare case of arytenoid mucosa oedema inducing stridor and cough, lasting 8 months, that critically affected the quality of life of a 15-year-old adolescent arrived to our emergency department with prominent arytenoid oedema causing paroxysmal cough and laryngeal stridor and that was successfully treated by laryngeal debridement. In this case report we observed that prominent swelling of arytenoid mucosa might sustain a vicious cycle of cough persistence and that laryngeal surgical debridement might interrupt it resolving the particular clinical condition. The description of this case could be of some help for clinicians to draw new insight about diagnosis and therapy of rare selected cases of chronic refractory cough.

Dillon, John P; Freedman, Ilan; Tan, James S M; Mitchell, David; English, Shaun

2012-07-01

Operative treatment for septic pre-patellar bursitis generally involves open debridement in addition to an extended course of intravenous antibiotics. Skin necrosis and wound breakdown are potential complications of this procedure in addition to scar sensitivity and a prolonged recovery. We report endoscopic bursectomy for the treatment of septic pre-patellar bursitis in eight patients over a 3-year period. All patients had microbiological confirmation of an infective process. The average age was 36 years (23-68 years). The average hospital stay was 6 days (4-9 days). No patient had a recurrence or complained of tenderness or hypoaesthesia around their wound. No patient experienced wound complications or skin necrosis. The average return to work time was 18 days (7-22 days). We conclude that endoscopic bursectomy is a safe and effective treatment for septic pre-patellar bursitis with a shortened hospital stay and a quicker return to work than conventional open debridement.

Systemic antimicrobial therapy (minocycline) as an adjunct to non-surgical approach to recurrent chronic generalized gingival hyperplasia.

PubMed

Khatri, Parag M; Bacha, Shraddanand

2014-03-01

Systemic antibiotic treatment has emerged as a powerful adjunct to conventional mechanical debridement for therapeutic management of the periodontal diseases. The conceptual basis for treating periodontal diseases as infections is particularly attractive in part because of substantial data indicating that these diseases may be associated with specific putative pathogens. Further, discrete groups of patients respond well to systemic antibiotics and exhibit improvement of clinical parameters, including attachment level and inflammation. This bacterial-host interaction, which is ever-so-present in periodontitis, directs us toward utilizing antimicrobial agents along with the routine mechanical debridement. This case report presents a case of a female patient with recurrence of the chronic generalized periodontitis with gingival enlargement, which is treated thrice by referral dentist. A through clinical examination was carried out pre-operatively and treatment was planned with systemic minocycline in conjunction with the conventional non-surgical approach. There was a significant reduction of pocket depth, gain in attachment with dramatic improvement clinically.

To demonstrate alterations of corneal K-structures (sub-Bowman's fibrous structures) after keratorefractive surgery by in vivo laser confocal microscopy and to look for association of K-structures with fluorescein-stained anterior corneal mosaic (ACM). Five patients (nine eyes) participated in this study. For four patients, one eye was evaluated after laser in situ keratomileusis (LASIK) and the other after epipolis-laser in situ keratomileusis (epi-LASIK). For one patient, the left eye was evaluated after epithelial debridement. A photograph of the ACM was obtained. Central corneal regions were scanned by Heidelberg Retina Tomograph 2 Rostock Cornea Module (Heidelberg Engineering GmbH, Heidelberg, Germany). The ACM and K-structures disappeared in all corneas after epi-LASIK, but not after LASIK and epithelial debridement cornea. The presence of K-structures and ACM may be an index to identify eyes that had a previous refractive surgical procedure (surface ablation or LASIK) and be a health index of Bowman layer and adjacent anterior stroma.

The purpose of this study was to compare periodontal tissue healing following flap surgery using an Er:YAG laser with that of conventional surgery. Bilateral premolars with experimentally induced periodontitis in six dogs were treated by periodontal flap surgery. Degranulation and root debridement in the furcation were performed using an Er:YAG laser or curet. At 3 months postsurgery, animals were sacrificed and decalcified specimens were prepared for histological and histometric analysis. Degranulation and root debridement were effectively performed with an Er:YAG laser without major thermal damage and significantly faster than with a curet. Histologically, the amount of newly formed bone was significantly greater in the laser group than in the curet group, although both groups showed similar amounts of cementum formation and connective tissue attachment. The Er:YAG laser irradiation can be safely and effectively utilized in periodontal flap surgery, and has the potential to promote new bone formation. Copyright 2006 Wiley-Liss, Inc.

This report describes the anesthetic management of a 14-yr-old, 160-kg, female Indo-Pacific bottlenose dolphin ( Tursiops aduncus ) that underwent surgical debridement for a refractory subcutaneous abscess twice within a 6-mo interval. The animal was otherwise in good physical condition at each anesthetic procedure. Following premedication with intramuscular midazolam and butorphanol, anesthesia was induced with propofol and maintained with sevoflurane by intubation. During surgery ventilation was controlled. Blood pressure was indirectly estimated using either oscillometric or pulse oximetry. Presumed hypotension was managed by adjusting the sevoflurane concentration and infusion of dopamine. During recovery, the dolphin regained adequate spontaneous respiration following intravenous administration of flumazenil and doxapram. The dolphin was extubated at 85 min and 53 min after the first and second surgeries, respectively. Successful weaning from the ventilator and initiation of spontaneous respiration was the most important complication encountered. Establishment of a reliable blood pressure measurement technique is critical to success for anesthesia in this species.

Diabetic foot ulcers (DFUs) are a major burden on the health-care system. The purpose of this study is to investigate factors affecting the healing rate of DFU in a university wound care center. Records of DFU patients treated between July 2013 and February 2015 were reviewed. Demographics, comorbidities, wound characteristics, and treatment modalities including offloading, hyperbaric oxygen treatment, total contact casting, and bioengineered skin were investigated. All patients underwent weekly debridement regardless of treatment modality. A total of 114 patients ages 18 to 98 comprised the study population. Total contact casting was the only treatment associated with increased healing (P = 0.02). Smoking (P = 0.004) and deep vein thrombosis history (P = 0.001) significantly decreased the likelihood of wound healing. Patients with past vascular event trended toward longer healing times (P = 0.07). Total contact casting in combination with weekly wound debridement showed benefit in DFU wound healing, whereas patients with a history of deep vein thrombosis and smoking were less likely to heal.

To assess the response to treatment in patients with soft tissue impingement of the ankle managed with arthroscopic debridement. Forty-one ankle arthroscopies were performed for soft tissue impingement between April 2007 and April 2009. There were 26 men and 15 women and the mean age was 30.1 years. Arthroscopy was performed on an average of 21 months after injury. The Visual-Analogue-Scale Foot and Ankle (VASFA) score and Meislin's criteria were used to assess the response to treatment. The mean pre-operative VASFA score was 44.5. This increased to 78.3 postoperatively (p < 0.0001). According to Meislin's criteria, there were 34 good or excellent results, five fair and two poor results. Pre-operative magnetic resonance imaging was useful in detecting tears of the anterior talofibular ligament and excluding osteochondral defects; however, synovitis and soft tissue impingement was under-reported. Arthroscopy is an effective method for the diagnoses and treatment of soft tissue impingement of the ankle joint. This condition is under-reported on MRI.

Operative management of acute pavement burns: a case series.

Acute burns suffered from contact with environmentally heated roadways and walkways are a rare entity. The aim of this report is to assess the information gained from the treatment of a series of patients. A retrospective review of a consecutive series of cases, where operative treatment was necessary, that occurred during July 2010 in southern Arizona. Seven patients were included, with an average total body surface area burn of 10.2%. Direct fascial excision and tangential excision were carried out on three and four patients, respectively. Although tangential excision was carried out to normal endpoints, there was commonly a need for repetitive debridement. The total hospital costs were over $4,400,000 (£2,730,000). Burns suffered from contact with roadways/walkways are often deeper than suggested by their appearance. Direct fascial excision minimises the number of debridement sessions. We hypothesise that the failure to offload pressure on these wounds may be a causative factor in their observed deepening.

To evaluate the feasibility of full-mouth debridement (subgingival scaling and root planning, SRP) by 2 times within 1 week and compare the clinical effects of different sequences of debridement-antibiotic usage in patients with severe chronic periodontitis (CP). A double-blinded, placebo-controlled, randomized clinical trial was conducted in 30 severe CP patients (14 males and 16 females, 40.5 ± 8.4 years old on average from 35 to 60) receiving 3 different sequences of debridement-antibiotictherapy: Group A, antibiotic usage (metronidazole, MTZ, 0.2 g, tid, 7 d; amoxicillin, AMX 0.5 g, tid, 7 d) was started together with SRP (completed by 2 times in 7 d); Group B, antibiotic usage (MTZ 0.2 g, tid, 7 d; AMX 0.5 g, tid, 7 d) was started 1 d after SRP(completed by 2 times in 7 d); Group C, SRP alone[probing depth (PD), bleeding index (BI) and tooth mobility] was examined. The average full-mouth probing depth, the average full-mouth proximal probing depth (pPD), the percentage of sites with PD>5 mm (PD>5 mm%), the percentage of sites with proximal PD>5 mm (pPD>5 mm%), the average bleeding index (BI) and the percentage of sites with bleeding on probing (BOP%) were calculated. Clinical examinations were performed at baseline and 2 months post therapy. (1) Compared with baseline conditions, all the subjects showed clinical improvements in all the parameters evaluated 2 months post therapy, P<0.05. (2) Significant difference were observed in the average PD changes between Group A [(2.15 ± 0.42) mm], Group B [(1.76 ± 0.29) mm] and Group C [(1.57 ± 0.33) mm], P<0.05. No significant difference was observed in the average PD changes between Group B and Group C, P=0.354. Significant differences were observed in the average pPD changes between Group A [(2.45 ± 0.43)mm] and Group C[(1.90 ± 0.48) mm], P<0.05. No significant difference was observed in BI and BOP% changes between Group A,Group B and Group C. For patients with severe chronic periodontitis, it is safe and feasible to receive full-mouth SRP by 2 times within 1 week. The short-term (2 months) advantages in PD changes are observed in patients receiving SRP and antibiotic usage at the same time comparing with patients using antibiotics after SRP or SRP alone.

Supportive periodontal therapy (SPT) for maintaining the dentition in adults treated for periodontitis.

PubMed

Manresa, Carolina; Sanz-Miralles, Elena C; Twigg, Joshua; Bravo, Manuel

2018-01-01

Periodontitis is a bacterially-induced, chronic inflammatory disease that destroys the connective tissues and bone that support teeth. Active periodontal treatment aims to reduce the inflammatory response, primarily through eradication of bacterial deposits. Following completion of treatment and arrest of inflammation, supportive periodontal therapy (SPT) is employed to reduce the probability of re-infection and progression of the disease; to maintain teeth without pain, excessive mobility or persistent infection in the long term, and to prevent related oral diseases.According to the American Academy of Periodontology, SPT should include all components of a typical dental recall examination, and importantly should also include periodontal re-evaluation and risk assessment, supragingival and subgingival removal of bacterial plaque and calculus, and re-treatment of any sites showing recurrent or persistent disease. While the first four points might be expected to form part of the routine examination appointment for periodontally healthy patients, the inclusion of thorough periodontal evaluation, risk assessment and subsequent treatment - normally including mechanical debridement of any plaque or calculus deposits - differentiates SPT from routine care.Success of SPT has been reported in a number of long-term, retrospective studies. This review aimed to assess the evidence available from randomised controlled trials (RCTs). To determine the effects of supportive periodontal therapy (SPT) in the maintenance of the dentition of adults treated for periodontitis. Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 8 May 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2017, Issue 5), MEDLINE Ovid (1946 to 8 May 2017), and Embase Ovid (1980 to 8 May 2017). The US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. Randomised controlled trials (RCTs) evaluating SPT versus monitoring only or alternative approaches to mechanical debridement; SPT alone versus SPT with adjunctive interventions; different approaches to or providers of SPT; and different time intervals for SPT delivery.We excluded split-mouth studies where we considered there could be a risk of contamination.Participants must have completed active periodontal therapy at least six months prior to randomisation and be enrolled in an SPT programme. Trials must have had a minimum follow-up period of 12 months. Two review authors independently screened search results to identify studies for inclusion, assessed the risk of bias in included studies and extracted study data. When possible, we calculated mean differences (MDs) and 95% confidence intervals (CIs) for continuous variables. Two review authors assessed the quality of evidence for each comparison and outcome using GRADE criteria. We included four trials involving 307 participants aged 31 to 85 years, who had been previously treated for moderate to severe chronic periodontitis. Three studies compared adjuncts to mechanical debridement in SPT versus debridement only. The adjuncts were local antibiotics in two studies (one at high risk of bias and one at low risk) and photodynamic therapy in one study (at unclear risk of bias). One study at high risk of bias compared provision of SPT by a specialist versus general practitioner. We did not identify any RCTs evaluating the effects of SPT versus monitoring only, or of providing SPT at different time intervals, or that compared the effects of mechanical debridement using different approaches or technologies.No included trials measured our primary outcome 'tooth loss'; however, studies evaluated signs of inflammation and potential periodontal disease progression, including bleeding on probing (BoP), clinical attachment level (CAL) and probing pocket depth (PPD).There was no evidence of a difference between SPT delivered by a specialist versus a general practitioner for BoP or PPD at 12 months (very low-quality evidence). This study did not measure CAL or adverse events.Due to heterogeneous outcome reporting, it was not possible to combine data from the two studies comparing mechanical debridement with or without the use of adjunctive local antibiotics. Both studies found no evidence of a difference between groups at 12 months (low to very low-quality evidence). There were no adverse events in either study.The use of adjunctive photodynamic therapy did not demonstrate evidence of benefit compared to mechanical debridement only (very low-quality evidence). Adverse events were not measured.The quality of the evidence is low to very low for these comparisons. Future research is likely to change the findings, therefore the results should be interpreted with caution. Overall, there is insufficient evidence to determine the superiority of different protocols or adjunctive strategies to improve tooth maintenance during SPT. No trials evaluated SPT versus monitoring only. The evidence available for the comparisons evaluated is of low to very low quality, and hampered by dissimilarities in outcome reporting. More trials using uniform definitions and outcomes are required to address the objectives of this review.

The Morel-Lavallée lesion is a closed degloving injury that usually occurs following high-energy trauma. We present a case demonstrating endoscopic management of this lesion. A 44-year-old man fell from scaffolding. Initial assessment demonstrated no significant injury. An ultrasound scan 2 days post injury revealed a large fluid collection along the lateral right thigh. This subsequently became infected and did not respond to antibiotic therapy.Due to the extent of the lesion, we were reluctant to perform a traditional open drainage. An endoscopic probe was inserted at the proximal and distal poles of the lesion and the wound debrided.This resulted in a rapid improvement in symptoms and a complete resolution of the lesion at 1 year postsurgery, with no wound-associated morbidity.This is only the second description of endoscopic debridement of a large, acute Morel-Lavallée lesion, with an excellent outcome. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Imam, Mohamed A.; Abdelkafy, Ashraf; Dinah, Feroz; Adhikari, Ajeya

2015-01-01

Background: The purpose of the current study was to determine whether a systematic five-step protocol for debridement and evacuation of bone debris during anterior cruciate ligament reconstruction (ACLR) reduces the presence of such debris on post-operative radiographs. Methods: A five-step protocol for removal of bone debris during arthroscopic assisted ACLR was designed. It was applied to 60 patients undergoing ACLR (Group 1), and high-quality digital radiographs were taken post-operatively in each case to assess for the presence of intra-articular bone debris. A control group of 60 consecutive patients in whom no specific bone debris protocol was applied (Group 2) and their post-operative radiographs were also checked for the presence of intra-articular bone debris. Results: In Group 1, only 15% of post-operative radiographs showed residual bone debris, compared to 69% in Group 2 (p < 0.001). Conclusion: A five-step systematic protocol for bone debris removal during arthroscopic assisted ACLR resulted in a significant decrease in residual bone debris seen on high-quality post-operative radiographs.

Guida, R.A.; Finn, D.G.; Buchalter, I.H.

1990-01-01

Osteoradionecrosis of the temporal bone is an unusual sequela of radiation therapy to the head and neck. Symptoms occur many years after the radiation is administered, and progression of the disease is insidious. Hearing loss (sensorineural, conductive, or mixed), otalgia, otorrhea, and even gross tissue extrusion herald this condition. Later, intracranial complications such as meningitis, temporal lobe or cerebellar abscess, and cranial neuropathies may occur. Reported here are five cases of this rare malady representing varying degrees of the disease process. They include a case of radiation-induced necrosis of the tympanic ring with persistent squamous debris in the external auditorymore » canal and middle ear. Another case demonstrates the progression of radiation otitis media to mastoiditis with bony sequestration. Further progression of the disease process is seen in a third case that evolved into multiple cranial neuropathies from skull base destruction. Treatment includes systemic antibiotics, local wound care, and debridement in cases of localized tissue involvement. More extensive debridement with removal of sequestrations, abscess drainage, reconstruction with vascularized tissue from regional flaps, and mastoid obliteration may be warranted for severe cases. Hyperbaric oxygen therapy has provided limited benefit.« less

The aim of this study was to compare the canal debridement capabilities of three single file systems, ProTaper, and K-files in oval-shaped canals. Seventy-five extracted human mandibular central incisors with oval-shaped root canals were selected. A radiopaque contrast medium (Metapex; Meta Biomed Co. Ltd., Chungcheongbuk-do, Korea) was introduced into the canal systems and the self-adjusting file (SAF), WaveOne, Reciproc, ProTaper, and K-files were used for the instrumentation of the canals. The percentage of removed contrast medium was calculated using pre- and post-operative radiographs. An overall comparison between the groups revealed that the hand file (HF) and SAF groups presented the lowest percentage of removed contrast medium, whereas the WaveOne group showed the highest percentage (P < 0.001). The ProTaper group removed more contrast medium than the SAF and HF groups (P < 0.05). None of the instruments was able to remove the contrast medium completely. WaveOne performed significantly better than other groups.

Objectives: The aim of this study was to compare the canal debridement capabilities of three single file systems, ProTaper, and K-files in oval-shaped canals. Materials and Methods: Seventy-five extracted human mandibular central incisors with oval-shaped root canals were selected. A radiopaque contrast medium (Metapex; Meta Biomed Co. Ltd., Chungcheongbuk-do, Korea) was introduced into the canal systems and the self-adjusting file (SAF), WaveOne, Reciproc, ProTaper, and K-files were used for the instrumentation of the canals. The percentage of removed contrast medium was calculated using pre- and post-operative radiographs. Results: An overall comparison between the groups revealed that the hand file (HF) and SAF groups presented the lowest percentage of removed contrast medium, whereas the WaveOne group showed the highest percentage (P < 0.001). The ProTaper group removed more contrast medium than the SAF and HF groups (P < 0.05). Conclusions: None of the instruments was able to remove the contrast medium completely. WaveOne performed significantly better than other groups. PMID:25202211

This review and case report present the treatment of a 10-year-old boy with both permanent maxillary lateral incisors demonstrating Oehlers type II dens invaginatus and pulpal involvement. Treatment was complicated by dental anxiety, supraventricular tachycardia, immature tooth development, and facial cellulitis. An infected necrotic pulp of the permanent maxillary left lateral incisor was treated by apexification and endodontic treatment with mineral trioxide aggregate. The necrotic pulp of the permanent maxillary right lateral incisor was treated with canal debridement and dressing under general anesthesia. Periapical healing of both teeth occurred, with the right lateral incisor showing continued root growth, thickening of the dentinal root walls, and completed apex formation. This tooth responded normally to pulp testing. Twenty-eight months after initial treatment, the right lateral incisor displayed progressive sclerosis of the canal. This case demonstrates possible pulpal regeneration of an infected maxillary right lateral incisor with dens invaginatus and an immature apex after minimal canal debridement.

Case report. To report on a patient with Pott disease, progressive neurologic deficit, and severe kyphotic deformity, who had medical treatment fail and required posterior/anterior decompression with instrumented fusion. Treatment options will be discussed. Tuberculous spondylitis is an increasingly common disease worldwide, with an estimated prevalence of 800,000 cases. Surgical treatment consisting of extensive posterior decompression/instrumented fusion and 3-level posterior vertebral column resection, followed by anterior debridement/fusion with cage reconstruction. Neurologic improvement at 6-month follow-up (Frankel B to Frankel D), with evidence of radiographic fusion. A 70-year-old patient with progressive Pott paraplegia and severe kyphotic deformity, for whom medical treatment failed is presented. A posterior vertebral column resection, multiple level posterior decompression, and instrumented fusion, followed by an anterior interbody fusion with cage was used to decompress the spinal cord, restore sagittal alignment, and debride the infection. At 6-month follow-up, the patient obtained excellent pain relief, correction of deformity, elimination of the tuberculous foci, and significant recovery of neurologic function.

BACKGROUND Severe lower extremity trauma as a devastating combat related injury is on the rise and this presents reconstructive surgeons with significant challenges to reach optimal cosmetic and functional outcomes. This study assessed early reconstructions of complex lower extremity battlefield soft tissue wounds. METHODS This was a prospective case series study of battled field injured patients which was done in the Department of Plastic Surgery, Baqiyatallah University of Medical Sciences hospitals, Tehran, Iran between 2013-2015. In this survey, 73 patients were operated for reconstruction of lower extremity soft tissue defects due to battlefield injuries RESULTS Seventy-three patients (65 men, 8 womens) ranging from 21-48 years old (mean: 35 years) were enrolled. Our study showed that early debridement and bone stabilization and later coverage of complex battlefields soft tissue wounds with suitable flaps and grafts of lower extremity were effective method for difficult wounds managements with less amputation and infections. CONCLUSION Serial debridement and bone stabilization before early soft tissue reconstruction according to reconstructive ladder were shown to be essential steps. PMID:29218283

Study Design: Multicenter retrospective case series and review of the literature. Objective: To determine the rate of esophageal perforations following anterior cervical spine surgery. Methods: As part of an AOSpine series on rare complications, a retrospective cohort study was conducted among 21 high-volume surgical centers to identify esophageal perforations following anterior cervical spine surgery. Staff at each center abstracted data from patients’ charts and created case report forms for each event identified. Case report forms were then sent to the AOSpine North America Clinical Research Network Methodological Core for data processing and analysis. Results: The records of 9591 patients who underwent anterior cervical spine surgery were reviewed. Two (0.02%) were found to have esophageal perforations following anterior cervical spine surgery. Both cases were detected and treated in the acute postoperative period. One patient was successfully treated with primary repair and debridement. One patient underwent multiple debridement attempts and expired. Conclusions: Esophageal perforation following anterior cervical spine surgery is a relatively rare occurrence. Prompt recognition and treatment of these injuries is critical to minimizing morbidity and mortality. PMID:28451488

2000-05-01

The spectrum of wounding and treatment of forty-one patients with musculoskeletal blast injuries at a U.S. military field hospital in the former Yugoslavia was reviewed. Patients underwent wound exploration, irrigation, debridement, broad-spectrum antibiotic therapy, early fracture stabilization, and appropriate reconstructive surgery. Four patients developed wound infections. Two patients died as a result of their injuries (overall mortality 5 percent). There were three below-knee amputations and five other amputations (above-knee, ankle, midtarsal, partial forefoot, and finger). Three patients sustained lumbar burst fractures from mines that exploded under their vehicles, resulting in paraplegia in one case. Our patients underwent 112 surgical procedures, an average of 2.1 per patient. Twenty-two patients (54 percent) had other injuries or conditions in addition to their orthopaedic wounds. There were wide variations in the bone and soft tissue injuries caused by detonating ordnance, and the tissue damage was qualitatively different from that caused by gunshot wounds. Early debridement, leaving wounds open, and treatment with broad-spectrum antibiotics were important factors in wound healing to allow subsequent successful reconstructive surgery in an austere field setting.

To review 7 patients with advanced osteoarticular tuberculous arthritis of the ankle who underwent arthrodesis using a supracondylar femoral nail. All patients showed gross destruction of the articular cartilage of the tibiotalar joint with severe periarticular rarefaction on radiographs. Their pre- and one-year post-operative Foot and Ankle Outcome Scores (FAOS) were compared. All patients underwent joint debridement, complete synovial excision, and arthrodesis using a supracondylar femoral nail, followed by multidrug chemotherapy for 12 months (isoniazid, rifampicin, pyrazinamide, and ethambutol for 3 months, and isoniazid and rifampicin for 9 months). All patients achieved fusion in a mean of 13 weeks and regained their preoperative level of independence. No patient had a relapse, major complications, or hardware failure. At postoperative year one, the mean FAOS for pain improved to 85 from 26, whereas the mean FAOS for quality of life improved to 60 from 5. Tibiotalocalcaneal arthrodesis using a supracondylar femoral nail, combined with debridement and multidrug therapy, enabled a reliable one-stage solution for advanced osteoarticular tuberculosis and early return to function.

A healthy 60-year-old male was initially treated for external otitis, and subsequently received multiple surgeries including abscess drainage, temporal bone debridement, canaloplasty of the external auditory meatus, and fistula excision and was treated with numerous antibiotics at another hospital over a 1-year period. He was seen at our hospital on February 14, 2014 with a complaint of a non-healing wound behind the left ear and drainage of purulent fluid. He had no history of diabetes mellitus or compromised immune function. Computed tomography (CT) and magnetic resonance imaging (MRI) studies at our hospital showed osteomyelitis involving the left temporal, occipital, and sphenoid bones, the mandible, and an epidural abscess. Routine blood testing and tests of immune function were normal, and no evidence of other infectious processes was found. He was diagnosed with malignant otitis externa (MOE). Bone debridement and incision and drainage of the epidural abscess were performed, and vancomycin was administered because culture results revealed Corynebacterium jeikeium, Corynebacterium xerosis, and Enterococcus faecalis. MOE should be considered in healthy patients with external otitis who fail initial treatment.

Meniscal tears can be incidentally encountered at the time of anterior cruciate ligament (ACL) reconstruction. In these cases, the surgeon has several treatment options that include benign neglect, debridement, trephination, and repair. The authors performed a systematic review of the literature studying the various treatment options for meniscal tears discovered at the time of ACL reconstruction. This systematic review included eight articles that had relevant data regarding benign neglect compared with debridement, trephination, or repair of incidentally encountered meniscal tears. Combined data from these studies resulted in a total of 646 meniscal tears treated with benign neglect with follow-up information available. Importantly, there were differences in reoperation rates between medial and lateral meniscal tears left in situ. However, stable medial and lateral meniscal tears treated with benign neglect did not have different subjective or objective outcomes than those treated with surgical intervention. This systematic review concludes that when stable meniscal tears are encountered at the time of arthroscopic ACL reconstruction, benign neglect can be used for a successful outcome.

2016-07-01

Mucormycosis is a rare but serious sequelae of penetrating trauma [1-5]. In spite of aggressive management, mortality remains high due to dissemination of infection. We completed a review of literature to determine the most optimal treatment of cutaneous mucormycosis which occurs secondary to penetrating trauma. We completed a review regarding the management of mucormycosis in trauma patients. We selected a total of 36 reports, of which 18 were case-based, for review. Surgical debridement is a primary predictor of improved outcomes in the treatment of mucormycosis [3,6,7]. Anti-fungal therapy, especially lipid soluble formulation of Amphotericin B, is helpful as an adjunct or when surgical debridement has been maximally achieved. Further research is needed to fully evaluate the impact of topical dressings; negative pressure wound therapy is helpful. An aggressive and early surgical approach, even at the expense of disfigurement, is necessary to reduce mortality in the setting of cutaneous mucormycosis that results from penetrating trauma [4,8,9]. Anti-fungal therapy and negative pressure wound therapy are formidable adjuncts. Copyright © 2016 Elsevier Ltd. All rights reserved.

2017-02-01

This study aimed to perform a systematic review of the effectiveness of nonsurgical treatment associated with different adjuvant therapies on periimplantitis. Different individuals, following a research process, performed a network research of controlled and randomized controlled clinical trials on PubMed, Embase/MEDLINE, with 20 years' time constraint and the last search in January 2016. From 108 articles found by the first search, they analyzed 10 full texts, and in none did they find a standard control group. When compared, mechanical therapies combined with adjuvant therapy decreased prevalence of periimplant ratios; however, some groups showed unsatisfactory results, mainly related to the probing depth and bleeding index. When comparing debridement with other nonsurgical therapies (Er:YAG, Vector, air abrasive with amino acid glycine powder), increased periimplant levels were noticed in the test and control groups, although in different periods. Despite the improvement in the periimplant indices, there is no sufficient evidence to score the best results or even to choose the best association for nonsurgical treatment of periimplantitis; hence, more trials are necessary to answer this question.

Avulsion fracture of the anterior tibial eminence is an uncommon injury. If bone union does not occur, knee extension will be limited by impingement of the avulsed fragment and knee instability will be induced by dysfunction of the anterior cruciate ligament (ACL). This report describes a 55-year-old woman who experienced an avulsion fracture of the right anterior tibial eminence during recreational skiing. Sixteen months later, she presented at our hospital with limitation of right knee extension. Plain radiography showed nonunion of the avulsion fracture region, and arthroscopy showed that the avulsed fragment impinged the femoral intercondylar notch during knee extension. The anterior region of the bony fragment was debrided arthroscopically until the knee could be extended completely. There was no subsequent instability, and the patient was able to climb a mountain 6 months after surgery. These findings indicate that arthroscopic debridement of an avulsed fragment for nonunion of an avulsion fracture of the anterior tibial eminence is a minimally invasive and effective treatment for middle-aged and elderly patients with a low level of sports activity.

An adult great-horned owl (Bubo virginianus; GHOW) presented with a history of recurrent corneal ulceration of the right eye (OD). Findings included ulcerative superficial keratitis, proliferative conjunctivitis, and iris pigmentary changes. The ulcer was initially nonresponsive to medical therapy, but showed rapid and appropriate healing following diamond burr debridement. Proliferative conjunctivitis markedly improved following topical antiviral therapy with cidofovir 1%, interferon alpha 2B ophthalmic solutions, and oral l-lysine. Histopathologic evaluation of a conjunctival biopsy revealed epithelial features suspicious for viral cytopathic changes and intranuclear structures suspicious for viral inclusions, suggestive of a possible viral-induced papillomatous conjunctivitis. A novel alphaherpesvirus, referred to as Strigid Herpesvirus 1 (StrHV1), was identified using PCR and gene sequencing. This case represents a new clinical manifestation of a previously unreported herpesvirus in the GHOW. Identification of the herpes virus was critical to administration of appropriate therapy and resolution of the conjunctivitis, and corneal epithelial debridement promoted resolution of the chronic corneal epithelial defect. © 2018 American College of Veterinary Ophthalmologists.

Mechanical reduction of infectious bacteria by using physical instruments is considered the principal therapeutic strategy for periodontal disease; addition of antibiotics is adjunctive. However, local antibiotic treatment, combined with conventional mechanical debridement, has recently been shown to be more effective in periodontitis subjects with type 2 diabetes. This suggests that some bacteria may invade the inflamed inner gingival epithelium, and mechanical debridement alone will be unable to reduce these bacteria completely. Therefore, we tried to establish infected organ culture models that mimic the inner gingival epithelium and aimed to see the effects of antibiotics in these established models. Mouse dorsal skin epithelia were isolated, and periodontal bacteria were injected into the epithelia. Infected epithelia were incubated with test antibiotics, and colony-forming ability was evaluated. Results indicated that effective antibiotics differed according to injected bacteria and the bacterial combinations tested. Overall, in organ culture model, the combination of amoxicillin or cefdinir and metronidazole compensate for the effects of less effective bacterial combinations on each other. This in vitro study would suggest effective periodontal treatment regimens, especially for severe periodontitis.

To describe the signalment, presence of systemic and/or ocular comorbidities, times to detected healing and probabilities of recurrence after diamond burr debridement (DBD) of eyes with presumed corneal calcareous degeneration and secondary ulceration and/or ocular pain. Twenty-six dogs with 42 eyes affected, 34 eyes treated with DBD. A case series was conducted using medical records from a private veterinary ophthalmology referral practice. Dogs were included if they had white or gray corneal opacity consistent with corneal calcareous degeneration with either erosive or superficial ulceration and/or ocular pain in at least one eye and had at least one such eye treated with DBD. DBD was performed with a battery-operated handheld motorized burr (The Alger Company, Inc. Lago Vista, TX, USA), and a bandage contact lens was placed in the majority of eyes (30/34). Eyes were considered healed when the cornea was fluorescein negative, and there were no signs of ocular pain. Patient data (signalment, recurrence) were extracted from medical records. Dogs were first re-examined 7-62 days after treatment (median: 13 days). All DBD-treated eyes healed within 62 days (% healed: 100%; one-sided 97.5% CI: 90-100%, median: 14 days), 82% of eyes (28/34) were healed at first re-examination (median: 13 days after treatment), and all were healed by their second examination (median: 24 days). Of the 34 treated eyes, 11 were lost to follow up; 11 of the remaining 23 eyes recurred. Estimated 1-year recurrence probability was 58% (95% CI: 35-83%). Seven dogs had systemic disease; 7 had a history of prior ocular disease or intraocular surgery. Diamond burr debridement is a safe and effective treatment for rapid resolution of superficial corneal ulceration and ocular pain secondary to presumed corneal calcareous degeneration in dogs. © 2015 American College of Veterinary Ophthalmologists.

Sericin is a major constituent of silk produced by silkworms. We previously found that the instillation of sericin enhanced the proliferation of corneal epithelial cells, and acted to promote corneal wound healing in both normal and diabetic model rats. However, the mechanisms by which sericin promotes the proliferation of corneal cells have not been established. In this study, we investigated the effects of sericin on Akt and ERK activation in a human corneal epithelial cell line (HCE-T cells) and rat debrided corneal epithelium. Although Akt phosphorylation was not detected following the treatment of HCE-T cells with sericin, ERK1/2 phosphorylation was enhanced. The growth of HCE-T cells treated with sericin was significantly increased, with the cell growth of sericin-treated HCE-T cells being 1.7-fold higher in comparison with vehicle-treated HCE-T cells. On the other hand, both of an ERK inhibitor U0126 (non-specific specific inhibitor) and SCH772984 (specific inhibitor) attenuated the enhanced cell growth by sericin, and the growth level in the case of co-treatment with sericin and ERK1/2 inhibitor was similar to that of cells treated with ERK1/2 inhibitor alone. In an in vivo study using rat debrided corneal epithelium, the corneal wound healing rate was enhanced by the instillation of sericin, and this enhancement was also attenuated by the instillation of U0126. In addition, the corneal wound healing rate in rats co-instilled with sericin and U0126 was similar to that following the instillation of U0126 alone. In conclusion, we found that the instillation of sericin enhanced cell proliferation via the activation of the MAPK/ERK pathway, resulting in the promotion of corneal wound healing in rat eyes. These findings provide significant information for designing further studies to develop potent corneal wound-healing drugs. PMID:29642540

The aim of this study is to evaluate clinical outcomes of a concept for non-surgical peri-implantitis combining stepwise mechanical debridement measures with adjuvant povidone-iodine application with and without systemic antibiotics. Forty-five patients with chronic periodontitis and a total of 164 screw-typed implants with peri-implantitis were included. Peri-implantitis was defined as radiographic bone loss of > 2 mm, probing depth (PD) ≥5 mm with bleeding on probing (BOP). Stepwise treatment of implants was performed with ultrasonic debridement, soft tissue curettage (STC), glycine powder air polishing (GPAP), and a repeated submucosal application of povidone-iodine. Teeth with PD > 4 mm were treated simultaneously according to the same concept except STC. In cases with severe periodontitis (n = 24), amoxicillin and metronidazole (AM) were prescribed for 7 days. After 12 months, implants treated without AM showed significant reductions (P < 0.05) of mean PD (1.4 ± 0.7 mm), clinical attachment level (CAL) (1.3 ± 0.8 mm), and BOP (33.4% ± 17.2%). In deep pockets (PD > 6 mm) changes of mean PD (2.3 ± 1.3 mm), CAL (2.0 ± 1.6 mm), and BOP (44.0% ± 41.7%) were more pronounced. Intake of AM did not significantly influence the changes in these parameters. However, the reduction of implant sites with PD > 4 mm and BOP was significantly higher in patients with AM than in those without AM (31.8% ± 12.6% versus 20.8% ± 14.7%; P < 0.05). The combination of ultrasonic debridement, STC, and GPAP with adjuvant povidone-iodine led to significant clinical improvements at implants. Systemic antibiotics had limited effects on the reduction of persisting implant sites with treatment need. © 2017 American Academy of Periodontology.

Treatment of peri-implantitis: clinical outcome of chloramine as an adjunctive to non-surgical therapy, a randomized clinical trial.

2017-01-01

To evaluate the adjunctive clinical effects of a chloramine to non-surgical treatment of peri-implantitis. Eighteen individuals diagnosed with peri-implantitis (clinical signs of inflammation and progressive bone loss) on at least two implants were included. Clinical variables; plaque accumulation (Pl), probing depth (PD), clinical attachment level (CAL) and bleeding on probing (BoP), were recorded at baseline and at 3-month follow-up. Primary clinical efficacy variable was the change in the number of sites with BoP. The implants were randomized into two different treatment groups: test and control. Both implants received supra- and submucosal debridement by ultrasonic instrumentation supplemented with hand instruments. The implants assigned to the test group first received local applications of a chloramine gel (Perisolv ™ ; RLS Global AB, Gothenburg, Sweden) followed by mechanical instrumentation. The oral hygiene was checked at 6 weeks. After 3 months, implants of both groups showed statistically significant reduction (P < 0.001) in the number of BoP-positive sites compared with baseline. The reduction of BoP-positive sites in the test group changed from 0.97 (SD ± 0.12) to 0.38 (SD ± 0.46), and in the control group from 0.97 (SD ± 0.12) to 0.31 (SD ± 0.42). Between-group comparisons revealed no statistically significant differences at baseline and after 3 months, for BoP or any of the other variables. In the present randomized clinical trial of peri-implantitis therapy; non-surgical mechanical debridement with adjunctive use of a chloramine is equally effective in the reduction of mucosal inflammation as conventional non-surgical mechanical debridement up to 3 months. © 2015 John Wiley & Sons A/S.

2016-05-01

The subgingival prevalence of gram-negative facultative rods not usually inhabiting or indigenous to the oral cavity (non-oral GNFR), as well as selected periodontal bacterial pathogens, were evaluated by culture in untreated and treated chronic periodontitis patients. Subgingival biofilm specimens from 102 untreated and 101 recently treated adults with chronic periodontitis in the Netherlands were plated onto MacConkey III and Dentaid selective media with air-5% CO2 incubation for isolation of non-oral GNFR, and onto enriched Oxoid blood agar with anaerobic incubation for recovery of selected periodontal bacterial pathogens. Suspected non-oral GNFR clinical isolates were identified to a species level with the VITEK 2 automated system. A total of 87 (42.9%) out of 203 patients yielded subgingival non-oral GNFR. Patients recently treated with periodontal mechanical debridement therapy demonstrated a greater prevalence of non-oral GNFR (57.4% vs 28.4%, P < 0.0001), and a greater number of different non-oral GNFR species (23 vs 14 different species), than untreated patients. Sphingomonas paucimobilis was the most frequently isolated subgingival non-oral GNFR species. Several GNFR species normally found in animals and human zoonotic infections, and not previously detected in human subgingival biofilms, were recovered from some patients, including Bordetella bronchispetica, Pasteurella canis, Pasteurella pneumotropica and Neisseria zoodegmatis. Porphyromonas gingivalis and Tannerella forsythia were significantly associated with the presence of subgingival non-oral GNFR. A surprisingly high proportion of Dutch chronic periodontitis patients yielded cultivable non-oral GNFR in periodontal pockets, particularly among those recently treated with periodontal mechanical debridement therapy. Since non-oral GNFR species may resist mechanical debridement from periodontal pockets, and are often not susceptible to many antibiotics frequently used in periodontal practice, their subgingival presence may complicate periodontal treatment in species-positive patients and increase risk of potentially dangerous GNFR infections developing at other body sites.

The purpose of this prospective, parallel group-designed, randomized controlled clinical study was the evaluation of the effectiveness of an air-abrasive device (AAD) for nonsurgical treatment of peri-implantitis. Twenty five patients, showing at least one implant with initial to moderate peri-implantitis, underwent an oral hygiene programme and were randomly treated using either (1) AAD (amino acid glycine powder) or (2) mechanical debridement using carbon curettes and antiseptic therapy with chlorhexidine digluconate (mechanical debridement (MDA)). Clinical parameters were measured at baseline and 12 months after treatment (e.g. bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL)). At 12 months, the AAD group revealed significantly higher (p < 0.05; unpaired t test) decrease in mean BOP scores when compared with MDA-treated sites (41.2 ± 29.5 vs. 16.6 ± 33.4%). Both groups exhibited comparable PD reductions (AAD = 0.5 ± 0.9 mm vs. MDA = 0.4 ± 0.9 mm) and CAL gains (AAD = 0.6 ± 1.3 mm vs. MDA = 0.5 ± 1.1 mm) (p > 0.05; Mann-Whitney test, respectively). Within its limitations, the present study has indicated that both treatment procedures resulted in comparable but limited CAL gains at 12 months. Furthermore, it could be detected that AAD was associated with significantly higher BOP decrease than MDA. The present results have indicated that nonsurgical therapy of peri-implantitis using both AAD and MDA resulted in comparable PD reductions and CAL gains after 12 months of healing. The BOP reductions were significantly higher in the AAD in comparison to the MDA group. So, AAD may be more effective for nonsurgical therapy of peri-implantitis than MDA.

Gas gangrene is a rapidly progressive bacterial infection leading to necrosis that usually develops as a result of trauma or postoperative complications. This condition requires early diagnosis with immediate surgical intervention. With a poor prognosis, a high incidence of amputation, and comorbidities such as diabetes and peripheral vascular disease, patients with gas gangrene are put at further risk for surgical complications. This case series reports the clinical outcomes of using a commercially available viable cryopreserved umbilical tissue (vCUT) in the surgical management of 10 patients (9 males, 1 female) with acute lower extremity gas gangrene. All 10 patients had aggressive debridement and irrigation, followed by an intraoperative application of vCUT to cover the large, complex wounds with exposed bone, tendon, and soft tissue, which was fenestrated and sutured to the surrounding skin edges. The average wound size following debridement was 45.9 cm2 (range, 8 cm2-105 cm2). Average percent area reduction of the wounds at 4 weeks post-vCUT application was 68.4% (range, 49%-99.5%). The average length of hospital stay was 9 days (range, 2-16 days), and postdischarge patients were treated with negative pressure wound therapy and standard of care (nonadherent dressing, dry gauze, and mild compression) until wound closure was achieved (average, 3.3 months [range, 1.25-4.5 months]). With a 1-time application of vCUT, all patients reached complete wound closure with decreased time to closure, fewer complications, and a shorter duration of hospitalization as compared with traditional inpatient management of gas gangrene (incision and drainage with staged procedures). The positive clinical outcomes indicate that vCUT may be an effective aid as an intraoperative application to cover wounds following aggressive debridement in the presence of gas gangrene.

Study Design Retrospective study. Purpose The aim of our study was to analyze the safety and effectiveness of posterior pedicle screw fixation for treatment of pyogenic spondylodiscitis (PSD) without formal debridement of the infected tissue. Overview of Literature Posterior titanium screw fixation without formal debridement of the infected tissue and anterior column reconstruction for the treatment of PSD is still controversial. Methods From March 2008 to June 2013, 18 patients with PSD underwent posterior titanium fixation with or without decompression, according to their neurological deficit. Postero-lateral fusion with allograft transplantation alone or bone graft with both the allogenic bone and the autologous bone was also performed. The outcome was assessed using the visual analogue scale (VAS) for pain and the Frankel grading system for neurological status. Normalization both of C-reactive protein (CRP) and erythrocyte sedimentation rate was adopted as criterion for discontinuation of antibiotic therapy and infection healing. Segmental instability and fusion were also analyzed. Results At the mean follow-up time of 30.16 months (range, 24–53 months), resolution of spinal infection was achieved in all patients. The mean CRP before surgery was 14.32±7.9 mg/dL, and at the final follow-up, the mean CRP decreased to 0.5±0.33 mg/dL (p <0.005). Follow-up computed tomography scan at 12 months after surgery revealed solid fusion in all patients. The VAS before surgery was 9.16±1.29 and at the final follow-up, it improved to 1.38±2.03, which was statistically significant (p <0.05). Eleven patients out of eighteen (61.11%) with initial neurological impairment had an average improvement of 1.27 grades at the final follow-up documented with the Frankel grading system. Conclusions Posterior screw fixation with titanium instrumentation was safe and effective in terms of stability and restoration of neurological impairment. Fixation also rapidly reduced back pain.

To explore effect and the application value of continuous douche and vacuum sealing drainage (VSD) in refractory tissue, and joint infections after complete debridement. As retrospective analysis of treatment time and restoration or recurrence, from Jan. 2006 to Dec. 2007, 61 cases of refractory tissue, bone and joint infections underwent continuous douche and VSD combined with the treatment of anti-inflammatory and rehabilitation training after debridement in our hospital. The 61 patients included 39 males and 22 females with age ranging from 10 to 58 years with an average of (35 +/- 12) years, among whom 61 identified to have ankle ulcers combined with infections,open fracture combined with infections, sacrococcygeal pressure ulcers combined with infections, infections after hip replacement, infections after open fracture, and infections after skin avulsion postoperation were 11, 15, 9, 3, 5 and 18 cases respectively. The course was from 2 weeks to 11 months with an average of 4 months. In all 61 patients,the mean healing time was 17, 36, 42, 24, 32, 29 and 28 days in ankle ulcers and infections, tibia and fibula open fracture and infections, femoral shaft fracture and infections, sacrococcygeal pressure ulcers and infections, infections after hip replacement, infections after open fracture, and infections after skin avulsion postoperation respectively. The replacement of VSD was 1, 2-4, 3-5, 1-3, 2-4, 2-3 and 1-3 times in each group respectively. There was no wound recurrence except for 2 cases with recurrent in 61 cases with external fixation nail hole semi-pathological fracture in 1 case of femoral shaft fracture and infection and 1 case of tibia and fibula fracture and infection after follow-up at least one year. Application of continuous douche and VSD can effectively decrease incidence of complications and promote the refractory tissue, bone and joint infections wound growth, healing and considerably shorten the healing time.

The present study was undertaken to examine the incidence and management of surgical site infection (SSI) in patients submitted to transapical transcatheter aortic valve implantation (TA-TAVI). From April 2007 to December 2011, 154 patients underwent TA-TAVI with an Edwards Sapien bioprosthesis (ES) at the Institut Universitaire de Cardiologie et Pneumologie de Québec (IUCPQ) as part of a multidisciplinary program to prospectively evaluate percutaneous aortic valve implantation. Patient demographics, perioperative variables, and postoperative complications were recorded in a prospective registry. Five (3.2%) patients in the cohort presented with an SSI during the study period. The infections were all hospital-acquired (HAI) and were considered as organ/space SSI's based on Center for Disease Control criteria (CDC). Within the first few weeks of the initial procedure, these patients presented with an abscess or chronic draining sinus in the left thoracotomy incision and were re-operated. The infection spread to the apex of the left ventricle in all cases where pledgeted mattress sutures could be seen during debridement. Patients received multiple antibiotic regimens without success until the wound was surgically debrided and covered with viable tissue. The greater omentum was used in three patients and the pectoralis major muscle in the other two. None of the patients died or had a recurrent infection. Three of the patients were infected with Staphylococcus epidermidis, one with Staphylococcus aureus, and one with Enterobacter cloacae. Patients with surgical site infections were significantly more obese with higher BMI (31.4±3.1 vs 26.2±4.4 p=0.0099) than the other patients in the cohort. While TA-TAVI is a minimally invasive technique, SSIs, which are associated with obesity, remain a concern. Debridement and rib resection followed by wound coverage with the greater omentum and/or the pectoralis major muscle were used successfully in these patients.

Full-thickness thoracic laminar erosion after posterior spinal fusion associated with late-presenting infection.

A case report describes unilateral complete laminar erosion of the caudal thoracic spine and late-presenting infection in a patient 10 years after anteroposterior reconstruction for scoliosis. To present an unusual but significant complication that may occur after implantation of spinal instrumentation. The reported patient presented with a deep infection and persistent back pain 10 years after successful anteroposterior reconstruction for adult idiopathic scoliosis. Delayed onset infections after implantation of spinal instrumentation are infrequent, yet when present, often require hardware removal. The case of a 51-year-old woman who underwent irrigation and debridement for a late-presenting infection and removal of posterior hardware 10 years after her index procedure is presented. Interoperatively, it was noted that full-thickness laminar erosion was present from T4 to T12. The patient was taken to the operating room for wound irrigation, debridement, and hardware removal. It was discovered that a Cotrel-Dubousset rod placed on the convexity of the curve had completely eroded through the lamina of T7-T12. Infectious material was found along the entire length of both the convex and concave Cotrel-Dubousset rods. Intraoperative cultures grew Staphylococcus epidermidis and Propionibacterium acnes. Intravenous and oral antibiotics were administered, resulting in resolution of the infection and preoperative pain. The exact role of late-presenting infection with regard to the laminar erosion and rod migration seen in this case remains to be elucidated. However, the authors believe the primary cause of bony erosion was mechanical in origin. Regardless, most spine surgeons will treat many patients who have had posterior spinal implants and will perform hardware removal on a significant number of these patients during their careers. A full-thickness laminar erosion exposes the spinal cord to traumatic injury during hardware removal and debridement. This case is presented as a cautionary note to help surgeons become cognizant of a potentially devastating complication.

A two-stage surgical strategy (debridement-negative pressure therapy (NPT) and flap coverage) with prolonged antimicrobial therapy is usually proposed in pressure ulcer-related pelvic osteomyelitis but has not been widely evaluated. Adult patients with pressure ulcer-related pelvic osteomyelitis treated by a two-stage surgical strategy were included in a retrospective cohort study. Determinants of superinfection (i.e., additional microbiological findings at reconstruction) and treatment failure were assessed using binary logistic regression and Kaplan-Meier curve analysis. Sixty-four pressure ulcer-related pelvic osteomyelitis in 61 patients (age, 47 (IQR, 36-63)) were included. Osteomyelitis was mostly polymicrobial (73%), with a predominance of S. aureus (47%), Enterobacteriaceae spp. (44%) and anaerobes (44%). Flap coverage was performed after 7 (IQR, 5-10) weeks of NPT, with 43 (68%) positive bone samples among which 39 (91%) were superinfections, associated with a high ASA score (OR, 5.8; p = 0.022). An increased prevalence of coagulase negative staphylococci (p = 0.017) and Candida spp. (p = 0.003) was observed at time of flap coverage. An ESBL Enterobacteriaceae spp. was found in 5 (12%) patients, associated with fluoroquinolone consumption (OR, 32.4; p = 0.005). Treatment duration was as 20 (IQR, 14-27) weeks, including 11 (IQR, 8-15) after reconstruction. After a follow-up of 54 (IQR, 27-102) weeks, 15 (23%) failures were observed, associated with previous pressure ulcer (OR, 5.7; p = 0.025) and Actinomyces spp. infection (OR, 9.5; p = 0.027). Pressure ulcer-related pelvic osteomyelitis is a difficult-to-treat clinical condition, generating an important consumption of broad-spectrum antibiotics. The lack of correlation between outcome and the debridement-to-reconstruction interval argue for a short sequence to limit the total duration of treatment.

Many aspects of the surgical treatment of patients with tuberculosis (TB) of the spine, including the use of instrumentation and the types of graft, remain controversial. Our aim was to report the outcome of a single-stage posterior procedure, with or without posterior decompression, in this group of patients. Between 2001 and 2010, 51 patients with a mean age of 62.5 years (39 to 86) underwent long posterior instrumentation and short posterior or posterolateral fusion for TB of the thoracic and lumbar spines, followed by anti-TB chemotherapy for 12 months. No anterior debridement of the necrotic tissue was undertaken. Posterior decompression with laminectomy was carried out for the 30 patients with a neurological deficit. The mean kyphotic angle improved from 26.1° (- 1.8° to 62°) to 15.2° (-25° to 51°) immediately after the operation. At a mean follow-up of 68.8 months (30 to 144) the mean kyphotic angle was 16.9° (-22° to 54°), with a mean loss of correction of 1.6° (0° to 10°). There was a mean improvement in neurological status of 1.2 Frankel grades in those with a neurological deficit. Bony union was achieved in all patients, without recurrent infection. Long posterior instrumentation with short posterior or posterolateral fusion is effective in the treatment of TB spine. It controls infection, corrects the kyphosis, and maintains correction and neurological improvement over time. With effective anti-TB chemotherapy, a posterior only procedure without debridement of anterior lesion is effective in the treatment of TB spondylitis, and an anterior procedure can be reserved for those patients who have not improved after posterior surgery.

Introduction Verrucae are extremely common, and are experienced by most people at some time during their lives. Although most verrucae will spontaneously disappear without treatment, many patients seek treatment, often because they have persisted for many years, are unsightly or painful or prevent them from doing sports or other activities. There are many different treatments available; including the Falknor's needling procedure. To date, there has only been one small trial evaluating the clinical effectiveness of this treatment and no health economic analysis has been undertaken. The Effective Verruca Treatments (EVerT2) trial aims to evaluate the clinical and cost-effectiveness of the needling procedure for the treatment of verrucae. Methods and analysis This single-centre randomised controlled trial will recruit 58 participants (aged 18 years and over with a plantar verruca) from Salford Podiatry Clinic patient lists and the surrounding area. If the participant presents with multiple verrucae, an ‘index’ verruca (largest and thickest lesion) will be identified and patients will be randomised 1:1 to the intervention group to receive the needling treatment or the control group to have the callus overlying the verruca debrided. The primary outcome is complete clearance of the index verruca at 12 weeks after randomisation. Secondary outcomes include clearance and recurrence of the treated verruca, clearance of all verrucae, number of verrucae remaining, change in size of the index verruca, pain, and participant satisfaction. A cost-effectiveness analysis of the needling versus callus debridement will be carried out from the perspective of health services over a time horizon of 12 weeks. Ethics and dissemination Ethical approval has been obtained from the University of Salford, Department of Health Sciences Ethical Approval Committee (HSCR15/24) and the University of York, Department of Health Sciences Research Governance Committee (HSRGC/2014/98/B). Findings will be disseminated through publication and conference presentations. Trial registration number ISRCTN16429440. PMID:26603251

This single case report (ABA design) was undertaken as a preliminary investigation into the clinical effects of low intensity laser upon venous ulceration, applied to wound margins only, and the potential relevance of wound debridement and wound measurement techniques to any effects observed. Ethical approval was granted by the University of Ulster's Research Ethical Committee and the patient recruited was required to attend 3 times per week for a total of 8 weeks. Treatments were carried out using single source irradiation (830 nm; 9 J/cm2, CB Medico, Copenhagen, Denmark) in conjunction with dry dressings during each visit. Assessment of wound surface area, wound appearance, and current pain were completed by an independent investigator. Planimetry and digitizing were completed for wound tracings and for photographs to quantify surface areas. Video image analysis was also performed on photographs of wounds. The primary findings were changes in wound appearance, and a decrease in wound surface area (range 33.3-46.3%), dependent on the choice of measurement method. Video image analysis was used, but rejected as an accurate method of wound measurement. Treatment intervention produced a statistically significant reduction in wound area using the C statistic on digitizing data for photographs (at Phase one only; Z = 2.412; p < 0.05). Wound debridement emerged as an important procedure to be carried out prior to measuring wounds. Despite fluctuating pain levels recorded throughout the duration of the study, VAS scores showed a decrease of 15% at the end of the study. This hypoalgesic effect was, however, statistically significant (using the C statistic) at Phase one only (Z = 2.554; p < 0.05). Low intensity laser therapy at this dosage, and using single source irradiation would seem to be an effective treatment for patients suffering venous ulceration. Further group studies are indicated to establish the most effective therapeutic dosage for this and other types of ulceration.

Altogether, 80 patients aged between 24 and 73 years with recurrent erosion of the cornea have been studied and compared with a control group of 200. The patients' erosions were divisible into macroform and microform types. The macroform occurred in 10%, the microform in 56%, and both types in the same patients in 31%. The macroform was more commonly related to trauma than the microform. However, many (40%) were spontaneous in origin. The most common cause of the initial trauma was a finger nail. The recurrences occurred at around the time of waking, either just before or just after. Difficulty in opening the eye occurred in 10%. There was little evidence of precipitating factors, but eye rubbing was admitted by 10% and barbiturates were implicated in 3%. The corneae were examined in the healed state, when a high incidence (59%) were found to have superficial corneal dystrophies of the fingerprint lines, bleb, and Bietti's lacunar (map-like) types. These are considered individually, particular attention being paid to the distinction between the various types of line resembling the fingerprint line. Epithelial microcysts were also a common finding (59%) and were sometimes of the Cogan type. In only 11% of patients were there no corneal signs in the healed state. The need for careful examination of the cornea by retroillumination, using both the iris and the fundus, is stressed. The control group, in contrast, showed a very low incidence of dystrophies and cysts. Treatment was given initially with either drops or ointment and no differences in healing were found. Debridement was performed in 12 eyes as an initial treatment and also in four eyes which were not healing on medical treatment. Debridement assisted healing, but did not prevent recurrence. One eye was treated with debridement and scarification and seven with carbolization. These procedures appeared to reduce the recurrence rate. Sodium chloride ointment 5% was found useful as a prophylactic taken at bedtime, and the recurrence rate increased when it was withdrawn. Images PMID:1083744

Abstract It was a retrospective analysis. The aim of the study was to explore the safety and reliability of emergency 1-stage radical debridement and reconstruction using titanium mesh filled with autologous bone for patients with cervical spine infection complicated by epidural abscess. At present, cervical spine infection complicated by epidural abscess is known as a severe spine disease. Recently, case report of this disease is showing quite an increasing tendency, particularly in economically undeveloped areas and countries. Regarding the treatment of this disease, 1-stage radical debridement and reconstruction has been widely adopted; however, emergency 1-stage anterior approach surgery without medication is considered as a relatively taboo, since it is generally acknowledged that such operation would possibly cause unexpected infection. Nevertheless, regular elective surgery may require longer time for preparation. In addition, long hour compression and stimulation of the abscess may leave the patients with irreversible spinal neural impairment. However, our department has finished 14 cases of cervical spine infection complicated with epidural abscess without 1 single case of postoperative infection. A retrospective study was conducted on 14 patients (9 males and 5 females; average age 57.4 years) who were diagnosed with cervical spine infection complicated by epidural abscess from January 2005 to December 2014. All the patients were admitted to hospital with varying degrees of neurological function losses, and then underwent 1-stage anterior focal debridement and reconstruction using titanium mesh within 24 hours after admission. They received postoperative standard antibiotic chemotherapy for 10 to 12 weeks. They were followed up for 18 to 36 months, an average of 27.4 months. X-ray, computed tomography (CT), and MRI (magnetic resonance imaging (MRI) were used to determine the fusion state and vertebral stability. American Spinal Injury Association (ASIA) international standards for neurological classification were adopted, white blood cell count (WBC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were evaluated to infection activity, and Japanese Orthopaedic Association (JOA) and visual analog scale (VAS) criteria were used to judge clinical efficacy. All the 14 patients had no postoperative spread of infection. No recurrence of infection was found during the last follow-up. ASIA grade, VAS score, and JOA score were significantly improved (P < .05) after the operation. WBC, ESR, and CRP became normal after the operation (P < .05). Postoperative follow-up imaging results showed no significant loss of cervical curvature, collapse of the grafted bone or implant displacement but good spinal canal volume. Emergency 1-stage radical debridement and reconstruction using titanium mesh filled with autologous bone, combined with antibiotic chemotherapy, is a safe and effective surgical therapy for cervical infection complicated by epidural abscess.

Mice are the small animal model of choice in biomedical research due to the low cost and availability of genetically engineered lines. However, the devices utilized in current mouse models of implant-associated bone infection have been limited to intramedullary or trans-cortical pins, which are not amenable to treatments involving extensive debridement of a full-thickness bone loss and placement of a segmental antibiotic spacer. To overcome these limitations, we developed a clinically faithful model that utilizes a locking fracture fixation plate to enable debridement of an infected segmental bone defect (full-thickness osteotomy) during a revision surgery, and investigated the therapeutic effects of placing an antibiotic-laden spacer in the segmental bone defect. To first determine the ideal time point for revision following infection, a 0.7 mm osteotomy in the femoral mid-shaft was stabilized with a radiolucent PEEK fixation plate. The defect was inoculated with bioluminescent Staphylococcus aureus, and the infection was monitored over 14 days by bioluminescent imaging (BLI). Osteolysis and reactive bone formation were assessed by X-ray and micro-computed tomography (micro-CT). The active bacterial infection peaked by 5 days post-inoculation, however the stability of the implant fixation became compromised by 10–14 days post-inoculation due to osteolysis around the screws. Thus, day 7 was defined as the ideal time point to perform the revision surgery. During the revision surgery, the infected tissue was debrided and the osteotomy was widened to 3 mm to place a poly-methyl methacrylate spacer, with or without vancomycin. Half of the groups also received systemic vancomycin for the remaining 21 days of the study. The viable bacteria remaining at the end of the study were measured using colony forming unit assays. Volumetric bone changes (osteolysis and reactive bone formation) were directly measured using micro-CT image analysis. Mice that were treated with local or systemic vancomycin did not display gross pathology at the end of the study. While localized vancomycin delivery alone tended to decrease the bacterial burden and osteolysis, these effects were only significant when combined with systemic antibiotic therapy. This novel mouse model replicates key features of implant-associated osteomyelitis that make treatment extremely difficult, such as biofilm formation and osteolysis, and imitates the clinical practice of placing an antibiotic-laden spacer after infected tissue debridement. In addition, the model demonstrates the limitations of current PMMA spacers and could be an invaluable tool for evaluating alternative antimicrobial treatments for implant-associated bone infection.

To investigate effectiveness of rotator cuff repair with manipulation release and arthroscopic debridement for rotator cuff tear with shoulder stiffness. A retrospectively study was performed on the data of 15 patients with rotator cuff tear combined with shoulder stiffness (stiff group) and 24 patients without stiffness (non-stiff group) between January 2014 and December 2015. The patients in the stiff group underwent arthroscopic rotator cuff repair with manipulation release and arthroscopic debridement while the patients in the non-stiff group only received arthroscopic rotator cuff repair. The patients in the stiff group were older than the patients in the non-stiff group, showing significant difference ( P <0.05). There was no significant difference in gender, type of rotator cuff tear, side of rotator cuff tear, and combined with diabetes between 2 groups ( P >0.05). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) were used to evaluate the effectiveness after operation. All incisions healed by first intention without any complication after operation. The patients were followed up 13-31 months in the stiff group (mean, 19.2 months) and 13-23 months in the non-stiff group (mean, 20.3 months). There was no significant difference in follow- up time between 2 groups ( t =-0.573, P =0.570). The VAS score in the stiff group was higher than that in the non-stiff group before operation ( t =-2.166, P =0.037); there was no significant difference between 2 groups at 3, 6, 12 months and last follow-up ( P >0.05). The forward flexion and external rotation were significantly lower in the stiff group than those in the non-stiff group before operation and at 3 months after operation ( P <0.05); there was no significant difference between 2 groups at 6, 12 months and last follow-up ( P >0.05). At last follow-up, the internal rotation was beyond L 3 level in 2 groups. The preoperative UCLA score was significant lower in the stiff group than that in the non-stiff group ( P =0.037); but there was no significant difference in UCLA score at last follow-up between 2 groups ( P =0.786). There was no significant difference in pre- and post-operative ASES scores between 2 groups ( P >0.05). Satisfactory effectiveness can be achieved in the patients with rotator cuff tear combined with shoulder stiffness after rotator cuff repair with manipulation release and arthroscopic debridement, although the patients with shoulder stiffness had slower postoperative recovery of ROM until 6 months after operation.

Peroneus longus tears associated with pathology of the os peroneum.

There is a range of different types of tears and pathology of the peroneal tendons. One of the least common types is the tear of the peroneus longus associated with fracture, enlargement, or entrapment at the cuboid tunnel of the os peroneum. The purpose of this study was to evaluate the pathologic patterns of these uncommon peroneal tendon tears, to review the treatment, and to report the patient outcomes following treatment with excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis. A 5-year retrospective review of all patients with peroneal tendon tears identified 12 patients operatively treated for peroneus longus tendon tears with associated pathology of the os peroneum, and in whom there was a viable peroneus brevis. All patients were treated with an operative procedure consisting of excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis. Mean age was 51.5 (range, 33 to 73) years, including 7 males and 5 females. Operative and radiographic records were reviewed to characterize the nature of the peroneus longus tears and associated pathology. Preoperative and postoperative AOFAS hindfoot, SF-36 questionnaires, and Visual Analog Scale (VAS) pain scores were compiled and patient records were reviewed for complications. Mean follow-up after surgery was 63.3 (range, 12 to 114) months. All of the patients had an os peroneum associated with a complex, irreparable tear of the peroneus longus tendon. The peroneus longus was typically enlarged, fibrotic, and adhered to the surrounding tissues. In 8 patients, the peroneus longus tendon tear was associated with a fracture of the os peroneum, and in 4 patients with an enlarged and entrapped os peroneum which prevented movement at the cuboid tunnel. Of the 12 patients, 9 had partial tears of the peroneus brevis, which were treated with debridement and suture repair. AOFAS hindfoot scores increased from a preoperative mean of 61 (range, 46 to 75) to a postoperative mean of 91.7 (range, 60 to 100). Mean preoperative SF-36 Physical Component Scores (PCS) increased from 36 to 52 postoperatively. Mean VAS pain scores decreased from a preoperative mean of 6.3 (range, 4 to 8) to a postoperative mean of 1.0 (range, 0 to 4). Complications included 2 patients with sural neuritis and 3 with superficial delayed wound healing successfully treated nonoperatively. Tears of the distal peroneus longus tendon, which are much less commonly reported than tears of the peroneus brevis, can be associated with pathology of the os peroneum. Excision of the os peroneum, tendon debridement, and tenodesis of the longus to brevis was an effective surgical technique. Level IV, case series.

Context: Invasion of the bifurcation and trifurcation of the multi-rooted teeth resulting in furcation involvement is one of the serious complications of periodontitis. Aim: The purpose of the study was to evaluate the efficacy of combination therapy using anorganic bovine bone graft and resorbable guided tissue regeneration (GTR) membrane versus open flap debridement alone in the management of Grade II furcation defects in mandibular molars. Materials and Methods: The study included a total number of 20 sites in 10 patients with bilateral mandibular furcation defects, out of which 10 sites were treated as test group and 10 as control group. The test group was treated with combination therapy and the control group with open flap debridement alone. The parameters were recorded on 0 day (baseline), 90th day, and 180th day, which included vertical probing depth and horizontal probing depth of the furcation defect, clinical attachment level, and defect fill. Statistical Analysis Used: Mean and standard deviation were calculated for different variables in each study group at different time points. Mean values were compared by using Wilcoxon signed ranks test, after adjusting the P values for multiple comparison by using Bonferroni correction method. Results: Both the test and control groups showed a definitive improvement in clinical parameters, which was statistically significant. On comparison, the vertical probing depth showed significant reduction in the test group with a mean reduction of 3.1 ± 0.7 mm, when compared to the control group which showed a mean reduction of 1.5 ± 0.5 mm. The horizontal probing depth of furcation defects was also significantly reduced in the test group with a mean reduction of 2.2 ± 0.6 mm, when compared to the control group in which the mean reduction was 0.9 ± 0.3 mm. There was also significant gain in attachment level in the test group which showed a mean gain of 3.2 ± 0.6 mm, when compared to the control group which showed a gain of 1.2 ± 0.6 mm. Radiographic defect fill was found to be more in the test group with a mean gain of 2.0 ± 0.1 mm, when compared to the control group which showed a defect fill of 0.2 ± 0.1 mm. Conclusions: The results of this study demonstrated that the combined use of anorganic bovine bone graft and resorbable GTR membrane is effective than open flap debridement alone in the treatment of mandibular grade II furcation defects.

2008-10-01

The purpose of this study was to evaluate contributing factors affecting deep infection and fracture healing of open tibia fractures treated with locked intramedullary nailing (IMN) by multivariate analysis. We examined 99 open tibial fractures (98 patients) treated with immediate or delayed locked IMN in static fashion from 1991 to 2002. Multivariate analyses following univariate analyses were derived to determine predictors of deep infection, nonunion, and healing time to union. The following predictive variables of deep infection were selected for analysis: age, sex, Gustilo type, fracture grade by AO type, fracture location, timing or method of IMN, reamed or unreamed nailing, debridement time (< or =6 h or >6 h), method of soft-tissue management, skin closure time (< or =1 week or >1 week), existence of polytrauma (ISS< 18 or ISS> or =18), existence of floating knee injury, and existence of superficial/pin site infection. The predictive variables of nonunion selected for analysis was the same as those for deep infection, with the addition of deep infection for exchange of pin site infection. The predictive variables of union time selected for analysis was the same as those for nonunion, excluding of location, debridement time, and existence of floating knee and superficial infection. Six (6.1%; type II Gustilo n=1, type IIIB Gustilo n=5) of the 99 open tibial fractures developed deep infections. Multivariate analysis revealed that timing or method of IMN, debridement time, method of soft-tissue management, and existence of superficial or pin site infection significantly correlated with the occurrence of deep infection (P< 0.0001). In the immediate nailing group alone, the deep infection rate in type IIIB + IIIC was significantly higher than those in type I + II and IIIA (P = 0.016). Nonunion occurred in 17 fractures (20.3%, 17/84). Multivariate analysis revealed that Gustilo type, skin closure time, and existence of deep infection significantly correlated with occurrence of nonunion (P < 0.05). Gustilo type and existence of deep infection were significantly correlated with healing time to union on multivariate analysis (r(2) = 0.263, P = 0.0001). Multivariate analyses for open tibial fractures treated with IMN showed that IMN after EF (especially in existence of pin site infection) was at high risk of deep infection, and that debridement within 6 h and appropriate soft-tissue managements were also important factor in preventing deep infections. These analyses postulated that both the Gustilo type and the existence of deep infection is related with fracture healing in open fractures treated with IMN. In addition, immediate IMN for type IIIB and IIIC is potentially risky, and canal reaming did not increase the risk of complication for open tibial fractures treated with IMN.

A successful treatment of necrotizing fasciitis following the surgery of distal radius plate removal: A case report and literature review.

PubMed

Cai, Yuchen; Gan, Yaokai; Yu, Chao; Tang, Jian; Sun, Yuehua

2018-04-01

Necrotizing fasciitis (NF) is defined as a rare, rapidly progressive, and highly lethal skin infection characterized by necrosis of the fascia and subcutaneous tissue. The present study aims to discuss the case of a 35-year-old man who developed NF following a routine sterile right distal radius bone plate removal surgery. The patient was suspected of NF based on his clinical manifestations, laboratory tests, and imaging results. The diagnosis of NF was confirmed by histological examinations. Serial prompt and extensive debridement was performed during the rapid and aggressive extension of the skin infection, together with antibiotics and supportive treatments. The condition of the patient finally improved on the sixth day of disease progression. Skin grafting of his right forearm wound was performed successfully 2 months after the admission. NF can occur during the perioperative period for routine clean radius plate removal operation in patients with no risk factor for NF. The objective is to remind the physicians to stay aware of this disease, especially its early clinical signs and symptoms. Urgent subsequent treatment, including surgical debridement, antibiotic therapy, and supporting management, is the key to ensure the survival and better prognosis of patients.

Traumatic abdominal hernia complicated by necrotizing fasciitis.

PubMed

2014-11-01

Necrotizing fasciitis is a critical illness involving skin and soft tissues, which may develop after blunt abdominal trauma causing abdominal wall hernia and representing a great challenge for physicians. A 52-year-old man was brought to the emergency department after a road accident, presenting blunt abdominal trauma with a large non-reducible mass in the lower-right abdomen. A first, CT showed abdominal hernia without signs of complication. Three hours after ICU admission, he developed hemodynamic instability. Therefore, a new CT scan was requested, showing signs of hernia complication. He was moved to the operating room where a complete transversal section of an ileal loop was identified. Five hours after surgery, he presented a new episode of hemodynamic instability with signs of skin and soft tissue infection. Due to the high clinical suspicion of necrotizing fasciitis development, wide debridement was performed. Following traumatic abdominal wall hernia (TAWH), patients can present unsuspected injuries in abdominal organs. Helical CT can be falsely negative in the early moments, leading to misdiagnosis. Necrotizing fasciitis is a potentially fatal infection and, consequently, resuscitation measures, wide-spectrum antibiotics, and early surgical debridement are required. This type of fasciitis can develop after blunt abdominal trauma following wall hernia without skin disruption.

History and clinical findings  We elaborate the case of a 72-year-old patient who presented with a painful swelling of the lower jaw in the emergency unit. Investigations and diagnosis  In the clinical examination and the CT scan, a widespread cervical emphysema was found which raised suspicion for the presence of a necrotizing fasciitis of the head and neck due to aerogenic infection. Close spatial vicinity to the teeth of the left upper and lower jaw was present, so that the necrotizing fasciitis was assumed to be odontogenic. Treatment and course  Based on the clinical presentation and the imaging findings the diagnosis of necrotizing fasciitis in the sense of a possible infection with gas building bacteria accompanying with an infection of the mediastinum was made. Immediately performed therapy included sternotomy and extended surgical debridement of necrosis. Conclusion  The presented case emphasizes that necrotizing fasciitis due to gas-producing infections should be considered as a differential diagnosis for cervical soft tissue emphysema for which an odontogenic focus is the most common cause. Rapid diagnosis is essential for successful treatment consisting of immediate surgical debridement and intravenous antibiotics. © Georg Thieme Verlag KG Stuttgart · New York.

Early prophylactic autogenous bone grafting in type III open tibial fractures.

The authors report the results achieved in patients with type III open tibial fractures who underwent primary autogenous bone grafting at the time of debridement and skeletal stabilisation. Twenty patients with a mean age of 35.8 years (range, 24-55) were treated between 1996 and 1999. Eight fractures were type IIIA, 11 were type IIIB, and 1 was type IIIC. At the index procedure, wound debridement, external fixation and autogenous bone grafting with bone coverage were achieved. The mean follow-up period was 46 months (range, 34-55). The mean time to fixator removal was 21 weeks (range, 14-35), and the mean time to union was 28 weeks (range, 19-45). Skin coverage was achieved by a myocutaneous flap in 2 patients, late primary closure in 4, and split skin grafting in 14. One (5%) of the patients experienced delayed union, and 1 (5%) developed infection. In tibial type III open fractures, skin coverage may be delayed, using the surrounding soft tissue to cover any exposed bone after thorough débridement and wound cleansing. Primary prophylactic bone grafting performed at the same time reduces the rate of delayed union, shortens the time to union, and does not increase the infection rate.

Ballistic trauma is not the prerogative of battlefields and currently extends to civil environments. Any surgeon or emergency room can be faced with such trauma whose management requires an understanding of wound ballistics. The aim of this retrospective is reviewing the management of ballistic trauma within the C.H.U. Saint-Pierre hospital over a period of ten years. Data recorded included demographics data, lesions, clinical parameters, imaging, treatment and outcome. It appears that the wounds of the members have a low mortality rate but a significant rate of complications. Patients should be managed according to the ATLS protocol and according hemodynamic stability and location of the injury, benefit from imaging. Unstable patients will be operated in emergency, stable patients will be treated according to the extent of damage and the type of fracture either conservatively or by external fixator and intramedullary centromedullary. Debridement and antibiotics are recommended as a nerve exploration if there is a peripheral paralysis. The management of trauma in our sample appear not optimal in light of the literature especially in terms of setting the vascular point of debridement, antibiotic and nerve repair resulting in significant consequences. Two management protocols according to patients' hemodynamic status are offered.

A 35-year-old male farmer came in contact with 11,000 volts high tension electric wire and sustained full thickness burn wounds over scapula, upper limb and anterior abdominal wall along with perforation of the intestine. Patient was initially managed conservatively in general surgery ward and was referred to us after 3 days with necrosis of the burned skin and muscles over the shoulder and abdomen. Patient was initially managed conservatively and then thorough debridement of the necrotic skin over the left shoulder and upper arm was done and the area was split skin grafted. Patient developed enterocutaneous fistula, which healed over a period of 8 weeks. The granulating wound over the abdomen was also skin grafted and patient was discharged after 18 days. About 4 months, after the discharge patient presented with ventral hernia. Repair of ventral hernia by synthetic mesh application and reconstruction of the abdominal wall with a free tensor fascia lata flap was done over the mesh, but the flap failed. Then after debridement two random pattern transposition skin flaps, one from the right upper and another from the left lower abdomen were transposed over the abdominal wound and donor area was skin grafted. Patient was discharged after 17 days.

Microbial infections delay wound healing, but the effect of the composition of the wound microbiome on healing parameters is unknown. To better understand bacterial communities in chronic wounds, we analyzed debridement samples from lower-extremity venous insufficiency ulcers using the following: conventional anaerobic and aerobic bacterial cultures; the Ibis T5000 universal biosensor (Abbott Molecular); and 16S 454 FLX titanium series pyrosequencing (Roche). Wound debridement samples were obtained from 10 patients monitored clinically for at least 6 months, at which point 5 of the 10 sampled wounds had healed. Pyrosequencing data revealed significantly higher bacterial abundance and diversity in wounds that had not healed at 6 months. Additionally, Actinomycetales was increased in wounds that had not healed, and Pseudomonadaceae was increased in wounds that had healed by the 6-month follow-up. Baseline wound surface area, duration, or analysis by Ibis or conventional culture did not reveal significant differences between wounds that healed after 6 months and those that did not. Thus, pyrosequencing identified distinctive baseline characteristics of wounds that did not heal by the 6-month follow-up, furthering our understanding of potentially unique microbiome characteristics of chronic wounds.

Use of 16S rRNA sequencing and quantitative PCR to correlate venous leg ulcer bacterial bioburden dynamics with wound expansion, antibiotic therapy, and healing

PubMed Central

Sprockett, Daniel D.; Ammons, Christine G.; Tuttle, Marie S.

2016-01-01

Clinical diagnosis of infection in chronic wounds is currently limited to subjective clinical signs and culture-based methods that underestimate the complexity of wound microbial bioburden as revealed by DNA-based microbial identification methods. Here, we use 16S rRNA next generation sequencing and quantitative polymerase chain reaction to characterize weekly changes in bacterial load, community structure, and diversity associated with a chronic venous leg ulcer over the 15-week course of treatment and healing. Our DNA-based methods and detailed sampling scheme reveal that the bacterial bioburden of the wound is unexpectedly dynamic, including changes in the bacterial load and community structure that correlate with wound expansion, antibiotic therapy, and healing. We demonstrate that these multidimensional changes in bacterial bioburden can be summarized using swabs taken prior to debridement, and therefore, can be more easily collected serially than debridement or biopsy samples. Overall, this case illustrates the importance of detailed clinical indicators and longitudinal sampling to determine the pathogenic significance of chronic wound microbial dynamics and guide best use of antimicrobials for improvement of healing outcomes.

Treatment of elbow osteomyelitis with an interposition arthroplasty using a rectus abdominis free flap.

PubMed

Jaiswal, Rohit; Busse, Brittany; Allen, Robert; Sahar, David

2015-05-01

Osteomyelitis of the elbow may be a complex clinical problem. Treatment goals include the eradication of infection and preservation of maximal joint function. Bony debridement may be necessary in addition to elbow joint arthroplasty. The use of synthetic material or allograft as the arthroplasty material may be contraindicated in the setting of infection. The use of free muscle transfer as an arthroplasty medium has not been well described. A 22-year-old paraplegic man developed recurrent osteomyelitis of the right elbow, necessitating extensive bony debridement by the orthopedic surgery team. Reconstruction arthroplasty was performed using a free rectus abdominis muscle flap as the arthroplasty material to serve as a source of biologically active, well-vascularized arthroplasty medium in the presence of ongoing infection. A successful free muscle flap arthroplasty was performed. External fixation and physical therapy were implemented postoperatively. The patient had resolution of osteomyelitis and excellent functional use of the elbow for activities of daily living and wheelchair motion. Elbow arthroplasty in the setting of active infection may be accomplished by means of free tissue muscle transfer. Elimination of infection and acceptable joint function may be possible with this form of reconstruction.

The current study aims to explore the clinical characteristics of craniocerebral firearm injury and to improve the diagnosis and treatment of this condition. Data from 56 patients with craniocerebral firearm injury were analyzed retrospectively for projectile types, traumatic conditions, and treatment approaches. 43 patients exhibited intracranial foreign body residence. Of them, 40 were subjected to complete foreign body removal and 2 to partial removal, leaving 1 without receiving removal treatment. 54 patients (96.4%) survived and 2 (3.6%) died. Of the survivors, 36 (64.3%) recovered well, 15 (26.8%) were moderately disabled, 2 (3.6%) were severely disabled, and 1 (1.8%) lapsed into vegetative state. Patients receiving debridement within 8 h after injury had a significantly higher recovery rate than those receiving such treatment after 8 h (82.1% vs. 26.7%; P < 0.001). Craniocerebral firearm injury is characterized by rapid traumatic condition development as well as serious trauma and contamination. Accurately judging the traumatic condition and the ballistic tract, performing complete debridement as early as possible, reasonably deciding on the operative mode and approach for intracranial residing foreign body removal, and increasing vigilance regarding concomitant injuries are the keys to the improvement of the overall treatment of craniocerebral firearm injury.

Scleritis Caused by In Vitro Linezolid-Resistant Nocardia asteroides

Purpose. To describe a case of postoperative scleritis caused by a novel strain of Nocardia resistant to linezolid and trimethoprim-sulfamethoxazole (TMP-SMX). Methods. Case report of a patient with microbiologically proven scleritis due to Nocardia asteroides. Results. The patient presented with pain, redness, and nodules on the sclera three months following pterygium excision with mitomycin C and amniotic membrane placement. As no response was noted with empiric treatment for bacterial scleritis, debridement was performed. The cytopathology report showed gram positive filamentous bacteria. A presumptive diagnosis of Nocardia scleritis was made and therapy was initiated based on a literature review on treatments for Nocardia infections. Cultures returned growing Nocardia asteroides. Antibiotic sensitivity testing revealed resistance to linezolid and TMP-SMX which are the traditional drugs of choice for Nocardia. The patient was treated with amikacin and imipenem as well as extensive debridement with pedicle grafts. The patient's scleritis resolved with a good visual outcome. Conclusions. Cultures should be obtained in all cases of necrotizing scleritis in patients with a recent history of conjunctival surgery to rule out unusual organisms such as Nocardia. Although literature states that resistance to linezolid and TMP-SMX is rare in Nocardia, sensitivity testing can be useful in unresponsive cases. PMID:25400961

Patient: Male, 62 Final Diagnosis: Sternoclavicular osteomyelitis Symptoms: — Medication: — Clinical Procedure: Debridement Specialty: Infectious Diseases Objective: Rare disease Background: Sternoclavicular osteomyelitis is a rare disease, with less than 250 cases identified in the past 50 years. We present a rare case of sternoclavicular osteomyelitis in an immunosuppressed patient that developed from a conservatively treated dislocation. Case Report: A 62-year-old white man with a history of metastatic renal cell carcinoma presented to the emergency department (ED) with a dislocated left sternoclavicular joint. He was managed conservatively and subsequently discharged. However, over subsequent days he began to experience pain, fever, chills, and night sweats. He presented to the ED again and imaging revealed osteomyelitis. In the operating room, the wound was aggressively debrided and a wound vac (vacuum-assisted closure) was placed. He was diagnosed with sternoclavicular osteomyelitis and placed on a 6-week course of intravenous Nafcillin. Conclusions: Chemotherapy patients who sustain joint trauma normally associated with a low risk of infection should be monitored thoroughly, and the option to discontinue immunosuppressive therapy should be considered if signs of infection develop.

Sachdeva, Surinder; Agarwal, Vipin

2011-01-01

Background: Chronic periodontitis is an inflammatory disorder caused by dental plaque having mixed microbial flora. The different treatment modalities available to treat this disease are aimed at removal of micro-organisms from both hard and soft tissues. Systemic as well as local anti-microbial agents are helpful adjuncts in reducing microbes especially in inaccessible areas along with mechanical debridement therapy. Materials and Methods: The study was conducted in a split mouth design. Thirty-five patients having at least two non-adjacent sites in different quadrants with periodontal pockets ≥5 mm and with bleeding on probing at initial visit were selected. The selected sites were treated with both scaling and root planing plus tetracycline fibers or with scaling and root planing alone. Baseline and follow-up measurements included plaque index, gingival index, probing pocket depth, and clinical attachment level. Result: Both treatment modalities were affective in improving clinical parameters over three months’ observation period. The combined antimicrobial and mechanical debridement therapy has shown better results as compared with scaling and root planing alone. Conclusion: Application of tetracycline in modified collagen matrix following scaling and root planing might be beneficial in treatment of chronic periodontitis and improving periodontal parameters for 3-month duration.

Invasive mycotic infections can be effectively treated if rapid identification of fungus is obtained. We reported a case of coinfection by Aspergillus and Rhizopus sp. involving nose, paranasal sinuses, orbit, and brain in a 68-year-old known hypertensive male. He was presented to ENT OPD with history of fever and intermittent headache since fifteen days along with history of right-sided nasal obstruction and proptosis since seven days. CT scan of brain and paranasal sinuses showed findings of pansinusitis with cellulitic changes in right orbit. MRI confirmed the same along with features of intracranial extension with focal meningitis in right frontotemporal region.

Invasive mycotic infections can be effectively treated if rapid identification of fungus is obtained. We reported a case of coinfection by Aspergillus and Rhizopus sp. involving nose, paranasal sinuses, orbit, and brain in a 68-year-old known hypertensive male. He was presented to ENT OPD with history of fever and intermittent headache since fifteen days along with history of right-sided nasal obstruction and proptosis since seven days. CT scan of brain and paranasal sinuses showed findings of pansinusitis with cellulitic changes in right orbit. MRI confirmed the same along with features of intracranial extension with focal meningitis in right frontotemporal region. Laboratory parameters did not conclude much except for leucocytosis and hyponatremia. Patient was taken for endoscopic debridement from nose and paranasal sinuses, and tissue was sent for microbiological and histopathological examination. Minced tissue was processed, and after 48 hrs of incubation two types of growth were identified, one was yellowish, granular, and powdery consistent with Aspergillus sp., and another was cottony and woolly consistent with Rhizopus sp. LCB mount confirmed presence of Aspergillus flavus and Rhizopus arrhizus. Patient responded to therapy with IV amphotericin B and surgical debridement. On discharge patient's condition was good.

This is a descriptive analysis, of victims of Turkey's October 23, 2011 and November 21, 2011 Van earthquakes. The goal of this study is investigated the injury profile of the both earthquakes in relation to musculoskeletal trauma. We retrospectively reviewed medical records of 3,965 patients admitted to in seven hospitals. A large share of these injuries were soft tissue injuries, followed by fractures, crush injuries, crush syndromes, nerve injuries, vascular injuries, compartment syndrome and joint dislocations. A total of 73 crush injuries were diagnosed and 31 of them were developed compartment syndrome. The patients with closed undisplaced fractures were treated with casting braces. For closed unstable fractures with good skin and soft-tissue conditions, open reduction and internal fixation was performed. All patients with open fracture had an external fixator applied after adequate debridement. Thirty one of 40 patients with compartment syndrome were treated by fasciotomy. For twelve of them, amputation was necessary. The most common procedure performed was debridement, followed by open reduction and internal fixation and closed reduction-casting, respectively. The results of this study may provide the basis for future development of strategy to optimise attempts at rescue and plan treatment of survivors with musculoskeletal injuries after earthquakes.

Conventional treatment of destructive periodontal (gum) disease arrests the disease but does not regain the bone support or connective tissue lost in the disease process. Guided tissue regeneration (GTR) is a surgical procedure that aims to regenerate the periodontal tissues when the disease is advanced and could overcome some of the limitations of conventional therapy. To assess the efficacy of GTR in the treatment of periodontal infra-bony defects measured against the current standard of surgical periodontal treatment, open flap debridement. We conducted an electronic search of the Cochrane Oral Health Group specialised trials register and MEDLINE up to October 2000. Hand searching included Journal of Periodontology, Journal of Clinical Periodontology, Journal of Periodontal Research and bibliographies of all relevant papers and review articles up to October 2000. In addition, we contacted experts/groups/companies involved in surgical research to find other trials or unpublished material or to clarify ambiguous or missing data and posted requests for data on two periodontal electronic discussion groups. Randomised, controlled trials of at least 12 months duration comparing guided tissue regeneration (with or without graft materials) with open flap debridement for the treatment of periodontal infra-bony defects. Furcation involvements and studies specifically treating early onset diseases were excluded. Screening of possible studies was conducted independently by two reviewers (RT & IN) and data abstraction by three reviewers (RT, IN & EGL). The methodological quality of studies was assessed in duplicate (RT & IN) using both individual components and a quality scale (Jadad 1998) and agreement determined by Kappa scores. Methodological quality was used in sensitivity analyses to test the robustness of the conclusions. The Cochrane Oral Health Group statistical guidelines were followed (HW) and the results expressed as weighted mean differences (WMD and 95% CI) for continuous outcomes and relative risk (RR and 95% CI) for dichotomous outcomes calculated using random effects models where significant heterogeneity was detected (P < 0.1). The final analysis was conducted using STATA 6 in order to combine both parallel group studies and intra-individual (split-mouth) studies. The primary outcome measure was gain in clinical attachment. Any heterogeneity was investigated. We initially included 23 trial reports. Twelve were subsequently excluded. Of these, seven presented six-months data only, three were not fully randomised controlled trials, one used a non-comparable radiographic technique. Eleven studies were finally included in the review, ten testing GTR alone and two testing GTR+bone substitutes (one study had both test treatment arms). For attachment level change, the weighted mean difference between GTR alone and open flap debridement was 1.11 mm (95% CI: 0.63 to 1.59), chi-square for heterogeneity 31.4 (df = 9), p<0.001) and for GTR+bone substitutes was 1.25 mm (95% CI: 0.89 to 1.61, chi-square for heterogeneity 0.01 (df = 1), p=0.91). GTR showed a significant benefit when comparing the numbers of sites failing to gain 2 mm attachment, with relative risk 0.58 (95% CI: 0.38, 0.88, chi-square for heterogeneity 5.72 (df = 3), p=0.13). The number needed to treat (NNT) for GTR to achieve one extra site gaining 2 mm or more attachment over open flap debridement was 8 (95% CI: 4, 33), based on an incidence of 32% of sites in the control group failing to gain 2 mm or more of attachment. For baseline incidences in the range of the control groups of 10% and 55% the NNTs are 24 and 3. Probing depth reduction demonstrated a small but statistically significant benefit for GTR, weighted mean difference 0.80 mm (95% CI: 0.14,1.46, chi-square for heterogeneity 10.0 (df = 4), p=0.04) or GTR+bone substitutes, weighted mean difference 1.24 mm (95% CI: 0.89, 1.59, chi-square for heterogeneity 0.03 (df = 1), p=0.85). No significant difference was noted for gingival recession between GTR and open flap debridement. Regarding hard tissue probing at surgical re-entry, a statistically significant greater gain was found for GTR compared with open flap debridement. This amounted to a weighted mean difference of 1.39 mm (95% CI: 1.08, 1.71, chi-square for heterogeneity 0.85 (df = 2), p=0.65). For GTR+bone substitutes the difference was greater, with mean difference 3.37 mm (95% CI: 3.14, 3.61). Heterogeneity between studies was highly statistically significant for all principal comparisons and could not be explained satisfactorily by sensitivity analyses. The quality of study reporting was poor with seven out of 11 studies graded as poor using the Jadad score. (ABSTRACT TRUNCATED)

Deep burns are associated with the formation of an eschar, which delays healing and increases the risk of infection. Surgical debridement of the eschar is, at present, the fastest means to achieve an eschar-free bed, but the process can not differentiate between the viable tissue and the eschar and follow the minute irregularities of the interface between the two. We evaluated the efficacy and selectivity of a novel enzymatic bromelain-based debriding agent, Debrase Gel Dressing (Debrase), in a porcine comb burn model. We hypothesized that Debrase would result in rapid debridement of the eschar without adverse effects on the surrounding uninjured skin. This is a prospective, controlled, animal experiment. Five domestic pigs (20-25 kg) were used in this study. Sixteen burns were created on each animal's dorsum using a brass comb with four rectangular prongs preheated in boiling water and applied for 30 seconds, resulting in four rectangular 10 x 20 mm full-thickness burns and separated by three 5 x 20 mm unburned interspaces representing the zone of stasis. The burned keratin layer (blisters) was removed, and the burns were treated with a single, topical, Debrase or control vehicle application for 4 hours. The Debrase/control was then wiped off using a metal forceps handle, and the burns were treated with a topical silver sulfadiazine (SSD). The wounds were observed, and full-thickness biopsies were obtained at 4 and 48 hours for evidence of dermal thickness, vascular thrombosis, and burn depth, both within the comb burns and the unburned interspaces in between them. Chi-square and t tests are used for data analysis. A single 4-hour topical application of Debrase resulted in rapid and complete eschar dissolution of all the burns in which the keratin layer was removed. The remaining dermis was thinner (1.1 +/- 0.7 mm) than in the control burns (2.1 +/- 0.3 mm; difference 0.9 mm [95% confidence interval: 0.3-1.4]) and was viable with no injury to the normal surrounding skin or to the unburned interspaces between the burns, which represents the zone of stasis. In control burns, the entire thickness of the dermis was necrotic. At 48 hours, Debrase-treated areas were found partially desiccated under SSD treatment. The unburned interspaces demonstrated partial-thickness necrosis in two third and full-thickness necrosis in one third of wounds. In contrast, full-thickness necrosis was noted in all control interspaces (P = .05). In a porcine comb burn model, a single, 4-hour topical application of Debrase resulted in rapid removal of the necrotic layer of the dermis with preservation of unburned tissues. At 48 hours, SSD treatment resulted in superficial tissue damage and partial preservation of the unburned interspaces.

Sulphur mustard (SM) is a potent incapacitating chemical warfare agent that remains a threat to war fighters and civilians worldwide. SM lesions may require weeks or months to heal, depending upon their severity. This study was undertaken to find a treatment regimen that promotes speedier healing of deep cutaneous SM burns in a weanling pig model. The principal objective of the study was to compare four treatment regimens and establish which achieved the shortest healing time. Twelve Yorkshire Cross weanling pigs were exposed to SM liquid for 2h, generating six large deep dermal/full thickness burns on the ventrum of each animal. Three additional animals served as sham-exposed controls. Surgical intervention occurred at 48 h postexposure. Treatments included: (i) full-thickness debridement of the burns with a computer controlled, raster scanned continuous wave CO2 laser followed by autologous split-thickness skin grafting; (ii) full-thickness sharp surgical tangential excision followed by skin grafting, the 'Gold Standard' used in human deep dermal/full-thickness thermal burns management; (iii) partial-thickness laser ablation with no grafting; and (iv) partial-thickness sharp surgical excision with no grafting. Several non-invasive bioengineering methods were used to monitor the progress of wound healing throughout a 36-day healing period: reflectance colourimetry, evaporimetry, laser Doppler perfusion imaging and ballistometry. Bioengineering methods indicated that laser debridement followed by autologous split-thickness skin grafting was as efficacious in improving the wound healing of deep SM burns in weanling swine as the 'Gold Standard.' Regardless of the method of debridement, barrier function, skin colour and mechanical properties returned to near-normal levels within 15 days of treatment in the grafted sites. Regardless of surgical approach, blood flux levels remained approximately 50-60% of normal tissue throughout the 36-day postsurgical observation period. Mid-dermal debridement by sharp surgical tangential excision or laser ablation without the use of skin grafts did not produce as good a result as those attained through the use of grafts, but was better than no surgical treatment of the wounds. Bioengineering methods were useful in evaluating multiple characteristics during wound healing: (i) reflectance colourimetry for skin colour, (ii) evaporimetry to measure transepidermal water loss as an indicator of barrier function, (iii) laser Doppler perfusion imaging to assess cutaneous blood flow, and (iv) ballistometry to measure the mechanical properties of skin hardness and elasticity. Perhaps the most useful method was evaporimetry, as a restored barrier function was the best indicator of healed wounds. The use of reflectance colourimetry and ballistometry will continue in future wound healing studies for their contributions in judging cosmetic and functional outcomes. While useful, laser Doppler perfusion imaging was found to be rather time consuming. This methodology will be limited in the future to burn depth estimation prior to treatment, and for evaluation of pharmaceuticals specifically designed to improve or sustain blood flow into damaged areas.

Sulfur mustard (2,2'-dichlorodiethyl sulfide; HD) is a potent vesicating chemical warfare agent that poses a continuing threat to both military and civilian populations. Significant cutaneous HD injuries can take several months to heal, necessitate lengthy hospitalizations, and result in long-term complications. There are currently no standardized or optimized methods of casualty management. New strategies are needed to provide for optimal and rapid wound healing. The primary aim of this research was to develop improved clinical strategies (treatment guidelines) for optimal treatment of superficial dermal (second degree) cutaneous HD injuries, with the goal of returning damaged skin to optimal appearance and normal function in the shortest period of time. Superficial dermal HD injuries were created on the ventral abdominal surface of weanling pigs. At 48h post-exposure, lesions were laser debrided and a treatment adjunct applied. Cultured epithelial allografts and 11 commercial off-the-shelf (COTS) products were examined for their efficacy in improving wound healing of these injuries. Clinical evaluations and a variety of non-invasive bioengineering methods were used at 7 and 14 days post-surgery to follow the progress of wound healing and evaluate various cosmetic and functional properties of the wounds. Measurements included reflectance colorimetry to measure erythema; evaporimetry to examine transepidermal water loss as a method of evaluating barrier function; torsional ballistometry to evaluate the mechanical properties of skin firmness and elasticity; and two-dimensional high frequency ultrasonography (HFU) to monitor skin thickness (e.g., edema, scar tissue). Histopathology and immunohistochemistry were performed 14 days following surgery to examine structural integrity and quality of healing. Logical Decisions((R)) for Windows was used to rank the 12 treatment adjuncts that were studied. The most efficacious treatment adjuncts included (1) Vacuum Assisted Closure, V.A.C., involving application of topical negative pressure, (2) Amino-Plex Spray (biO(2) Cosmeceuticals International, Inc., Beverly Hills, CA), a nutritive cosmeceutical product that is designed to increase oxygen in cells, stimulate ATP synthesis, improve glucose transportation, stimulate collagen formation, and promote angiogenesis, and (3) ReCell Autologous Cell Harvesting Device (Clinical Cell Culture Americas LLC, Coral Springs, Florida), an innovative medical device that was developed to allow rapid harvesting of autologous cells from a thin split-thickness biopsy followed by spray application of a population of skin cells onto wounds within 30 min of collecting the biopsy, without the need of culturing the keratinocytes in a clinical laboratory. Complete re-epithelialization of debrided HD injuries in 7 days is possible. In general, shallow laser debridement through the basement membrane zone (100 microm) appears to provide better results than deeper debridement (400 microm) with respect to early re-epithelialization, cosmetic appearance, functional restoration, and structural integrity. Of the 12 treatment adjuncts examined, the most promising included Vacuum Assisted Closure, Amino-Plex Spray, and ReCell Autologous Cell Harvesting Device.

Biologically active means are effective for rapidly removing scar tissue caused by burns or corrosive agents. Specially selected strain of bacteria applied to injury site releases enzymes which are active against eschar. These bacteria tend to locate between eschar and unburned tissue, thus providing optimal cell surface area arrangement for enzyme dispersal. Procedure may prove especially useful in treatment of disaster casualties under relatively primitive conditions.

The civilian gunshot wound is a low velocity injury. Temporary cavitation does not occur in the low velocity wound and damage is confined to the projectile pathway. Extensive debridement is not indicated for this injury. Surgical cleansing is used to convert the open, contaminated wound to a clean, closed wound. Reparative and definitive reconstruction then follow to restore form and function with minimized patient hazard.

Using multimodal imaging techniques to monitor limb ischemia: a rapid noninvasive method for assessing extremity wounds

Over 70% of military casualties resulting from the current conflicts sustain major extremity injuries. Of these the majority are caused by blasts from improvised explosive devices. The resulting injuries include traumatic amputations, open fractures, crush injuries, and acute vascular disruption. Critical tissue ischemia—the point at which ischemic tissues lose the capacity to recover—is therefore a major concern, as lack of blood flow to tissues rapidly leads to tissue deoxygenation and necrosis. If left undetected or unaddressed, a potentially salvageable limb may require more extensive debridement or, more commonly, amputation. Predicting wound outcome during the initial management of blast wounds remains a significant challenge, as wounds continue to "evolve" during the debridement process and our ability to assess wound viability remains subjectively based. Better means of identifying critical ischemia are needed. We developed a swine limb ischemia model in which two imaging modalities were combined to produce an objective and quantitative assessment of wound perfusion and tissue viability. By using 3 Charge-Coupled Device (3CCD) and Infrared (IR) cameras, both surface tissue oxygenation as well as overall limb perfusion could be depicted. We observed a change in mean 3CCD and IR values at peak ischemia and during reperfusion correlate well with clinically observed indicators for limb function and vitality. After correcting for baseline mean R-B values, the 3CCD values correlate with surface tissue oxygenation and the IR values with changes in perfusion. This study aims to not only increase fundamental understanding of the processes involved with limb ischemia and reperfusion, but also to develop tools to monitor overall limb perfusion and tissue oxygenation in a clinical setting. A rapid and objective diagnostic for extent of ischemic damage and overall limb viability could provide surgeons with a more accurate indication of tissue viability. This may help reducing the number of surgical interventions required, by aiding surgeons in identifying and demarcating areas of critical tissue ischemia, so that a more adequate debridement may be performed. This would have obvious benefits of reducing patient distress and decreasing both the overall recovery time and cost of rehabilitation.

Aspergillus Osteomyelitis of the Ribs in Immunocompetent Hosts: Report of Two Rare Cases

PubMed Central

Menon, Aditya; Rodrigues, Camilla; Soman, Rajeev; Sunavala, Ayesha; Agashe, Vikas M

2017-01-01

Introduction: Osteomyelitis is rarely caused by fungi, most common among them being Candida. Aspergillus is a rare cause of fungal osteomyelitis mimics tuberculous osteomyelitis. Aspergillus osteomyelitis (AO) of the ribs is relatively uncommon, with an incidence rate of only 9% among all reported cases of AO. With mortality rates of almost 25%, AO is on the rise attributed to increasing numbers of immunocompromised individuals. There are very few case reports of AO of ribs in immunocompetent individuals. We report two such cases. Case Report: Case 1: A 51-year-old male developed spontaneous chest pain along right costal margin with a low-grade fever. High-resolution computed tomography chest revealed osteomyelitis of anterolateral chest wall. He did not improve with empirical antitubercular therapy, and subsequent debridement showed polymicrobial pyogenic infection which was managed with appropriate antibiotics elsewhere. Samples were not sent for fungal culture. He presented to us 3 months later, and surgical debridement showed growth of Aspergillus flavus which was managed with oral voriconazole. The lesion healed with no recurrence at 24-month follow-up. Case 2: A 40-year-old male presented to our institute with left-sided chest pain, low-grade fever, and loss of appetite. There was a history of injury with a sharp piece of wood 2 years earlier. Magnetic resonance imaging defined the lesion which was biopsied under ultrasound guidance. Cultures grew A. flavus which was treated with oral voriconazole. He had complete clinical improvement at 16-month follow-up. Conclusion: More number of AO cases are being reported in immunocompetent individuals. Variability in clinical picture, rarity, misdiagnosis, empirical therapy, and failure to send deep tissue samples for fungal cultures are some of the reasons for the high mortality rates. It is paramount in today’s scenario of atypical presentations, to obtain deep tissue for all cultures including fungal culture and histopathology, either surgically or under image guidance to achieve good clinical outcomes. Our study highlights that following the strict protocol of obtaining tissue for fungal culture, systemic antifungal therapy, and surgical debridement where necessary can help to diagnose and treat this rare pathology and ensure the good clinical outcome.

Necrotizing fasciitis is a rare condition with a mortality rate of around 34%. It can be mono- or polymicrobial in origin. Monomicrobial infections are usually due to group A streptococcus and their incidence is on the rise. They normally occur in healthy individuals with a history of trauma, surgery or intravenous drug use. Post-operative necrotizing fasciitis is rare but accounts for 9 to 28% of all necrotizing fasciitis. The incidence of wound infection following saphenofemoral junction ligation and vein stripping is said to be less than 3%, although this complication is probably under-reported. We describe a case of group A streptococcus necrotizing fasciitis following saphenofemoral junction ligation and vein stripping. A 39-year-old woman presented three days following a left sided saphenofemoral junction ligation with long saphenous vein stripping at another institution. She had a three day history of fever, rigors and swelling of the left leg. She was pyrexial and shocked. She had a very tender, swollen left groin and thigh, with a small blister anteriorly and was in acute renal failure. She was prescribed intravenous penicillin and diagnosed with necrotizing fasciitis. She underwent extensive debridement of her left thigh and was commenced on clindamycin and imipenem. Post-operatively, she required ventilatory and inotropic support with continuous veno-venous haemofiltration. An examination 12 hours after surgery showed no requirement for further debridement. A group A streptococcus, sensitive to penicillin, was isolated from the debrided tissue. A vacuum assisted closure device was fitted to the clean thigh wound on day four and split-skin-grafting was performed on day eight. On day 13, a wound inspection revealed that more than 90% of the graft had taken. Antibiotics were stopped on day 20 and she was discharged on day 22. Necrotizing fasciitis is a very serious complication for a relatively minor, elective procedure. To the best of our knowledge, this is the first report in the English-language literature of this complication arising from a standard saphenofemoral junction ligation and vein stripping. It highlights the need to be circumspect when offering patients surgery for non-life-threatening conditions.

Pressure ulcer (PU) treatment poses significant clinical and economic challenges to health-care systems. The aim of this study was to assess the cost-effectiveness and budget impact of enzymatic debridement with clostridial collagenase ointment (CCO) compared with autolytic debridement with medicinal honey (MH) for PU treatment from a US payer/Medicare perspective in the hospital outpatient department setting. A cost-effectiveness analysis using a Markov model was developed using a 1-week cycle length across a 1-year time horizon. The three health states were inflammation/senescence, granulation/proliferation (ie, patients achieving 100% granulation), and epithelialization. Data sources included the US Wound Registry, Medicare fee schedules, and other published clinical and cost studies about PU treatment. In the base case analysis over a 1-year time horizon, CCO was the economically dominant strategy (ie, simultaneously conferring greater benefit at less cost). Patients treated with CCO experienced 22.7 quality-adjusted life weeks (QALWs) at a cost of $6,161 over 1 year, whereas MH patients experienced 21.9 QALWs at a cost of $7,149. Patients treated with CCO achieved 11.5 granulation weeks and 6.0 epithelization weeks compared with 10.6 and 4.4 weeks for MH, respectively. The number of clinic visits was 40.1 for CCO vs 43.4 for MH, and the number of debridements was 12.3 for CCO compared with 17.6 for MH. Probabilistic sensitivity analyses determined CCO dominant in 72% of 10,000 iterations and cost-effective in 91%, assuming a benchmark willingness-to-pay threshold of $50,000/quality-adjusted life year ($962/QALW). The budget impact analysis showed that for every 1% of patients shifted from MH to CCO, a cost savings of $9,883 over 1 year for a cohort of 1,000 patients was observed by the payer. The results of these economic analyses suggest that CCO is a cost-effective, economically dominant alternative to MH in the treatment of patients with PUs in the hospital outpatient department setting.

Periprosthetic joint infection (PJI) is a devastating complication after total joint arthroplasty, occurring in approximately 1%-2% of all cases. With growing populations and increasing age, PJI will have a growing effect on health care costs. Many risk factors have been identified that increase the risk of developing PJI, including obesity, immune system deficiencies, malignancy, previous surgery of the same joint and longer operating time. Acute PJI occurs either postoperatively (4 wk to 3 mo after initial arthroplasty, depending on the classification system), or via hematogenous spreading after a period in which the prosthesis had functioned properly. Diagnosis and the choice of treatment are the cornerstones to success. Although different definitions for PJI have been used in the past, most are more or less similar and include the presence of a sinus tract, blood infection values, synovial white blood cell count, signs of infection on histopathological analysis and one or more positive culture results. Debridement, antibiotics and implant retention (DAIR) is the primary treatment for acute PJI, and should be performed as soon as possible after the development of symptoms. Success rates differ, but most studies report success rates of around 60%-80%. Whether single or multiple debridement procedures are more successful remains unclear. The use of local antibiotics in addition to the administration of systemic antibiotic agents is also subject to debate, and its pro's and con's should be carefully considered. Systemic treatment, based on culture results, is of importance for all PJI treatments. Additionally, rifampin should be given in Staphylococcal PJIs, unless all foreign material is removed. The most important factors contributing to treatment failure are longer duration of symptoms, a longer time after initial arthroplasty, the need for more debridement procedures, the retention of exchangeable components, and PJI caused by Staphylococcus (aureus or coagulase negative). If DAIR treatment is unsuccessful, the following treatment option should be based on the patient health status and his or her expectations. For the best functional outcome, one- or two-stage revision should be performed after DAIR failure. In conclusion, DAIR is the obvious choice for treatment of acute PJI, with good success rates in selected patients.

Complications and failure of vertebroplasty, such as cement dislodgement, cement leakage, or spinal infection, usually result in spinal instability and neural element compression. Combined anterior and posterior approaches are the most common salvage procedure for symptomatic failed vertebroplasty. The purpose of this study is to evaluate the feasibility and efficacy of a single posterior approach technique for the treatment of patients with symptomatic failed vertebroplasty. Ten patients with symptomatic failed vertebroplasty underwent circumferential debridement and anterior reconstruction surgery through a single-stage posterior transpedicular approach (PTA) from January 2009 to December 2011 at our institution. The differences of visual analog scale (VAS), neurologic status, and vertebral body reconstruction before and after surgery were recorded. The clinical outcomes of patients were categorized as excellent, good, fair, or poor based on modified Brodsky's criteria. The symptomatic failed vertebroplasty occurred between the T11 and L3 vertebrae with one- or two-level involvement. The average VAS score was 8.3 (range, 7 to 9) before surgery, significantly decreased to 3.2 (range, 2 to 4) after surgery (p < 0.01), and continued to decrease to 2.4 (range, 2 to 3) 1 year later (p < 0.01). The average correction of Cobb's angle after surgery was 17.3° (range, 4° to 35°) (p < 0.01). The mean loss of Cobb's angle correction after 1 year of follow-up was 2.7° (range, 0° to 5°). The average allograft subsidence at 1 year after surgery was 1 mm (range, 0 to 2). The neurologic status of Frankel's scale significantly improved after surgery (p = 0.014) and at 1 year after surgery (p = 0.046). No one experienced severe complications such as deep wound infection or neurologic deterioration. All patients achieved good or excellent outcomes after surgery based on modified Brodsky's criteria (p < 0.01). Single-stage PTA surgery with circumferential debridement and anterior reconstruction technique provides good clinical outcomes and low complication rate, which can be considered as an alternative method to combined anterior and posterior approaches for patients with symptomatic failed vertebroplasty.

The purpose of this investigation is to report on trends over time in the treatment of meniscal pathology among military orthopaedic surgeons, as well as to evaluate the impact of patient demographics and concomitant procedure on the type of meniscal procedure performed. We performed a retrospective analysis of all active-duty United States military servicemembers who underwent a meniscal procedure from 2010 to 2015 within the Military Health System. Patient demographics and surgical variables were extracted from the electronic medical record. Treatments were categorized by location and by type of intervention (i.e., repair or debridement). Chi-square and linear regression analyses were performed to identify temporal trends in meniscal procedures and factors that were correlated with the type of meniscal procedure performed. Out of 29,571 meniscal procedures analyzed, partial meniscectomy was performed in 81.3% ( n  = 24,343) of cases, meniscal repair in 20.3% ( n  = 6,073), and meniscus allograft transplantation (MAT) in 0.7% ( n  = 206). The rates of debridement, repair, and concomitant surgeries did not demonstrate any significant temporal trends, whereas MAT demonstrated a significant decrease in overall utilization. Nearly two-thirds of all meniscal procedures were performed in the medial compartment. MAT occurred equally between the medial and lateral compartments. Lateral meniscal lesions demonstrated significantly higher rates of debridement. With each year of advancing age, there was a 3.7% increasing likelihood of meniscectomy and 6.5% decreasing likelihood of repair. Females were more likely to undergo meniscal repair than males. Patients in the military population were more likely to undergo meniscal repair compared with previously reported rates in the civilian population. In this physically active cohort of nearly 30,000 military patients, 1 in 5 meniscal tears were treated with meniscal repair. Meniscal repairs were performed at a higher rate for all age groups compared with previously reported rates in the civilian population. Further research is required to elucidate the causative factors behind these differences and the effect on postoperative outcomes. IV, cross-sectional study.

INTRODUCTION It has been known for centuries that maggots are potent debriding agents capable of removing necrotic tissue and slough. In January 2004, the US Food and Drug Administration decided to regulate maggot debridement therapy (MDT). As it is still not clear which wounds are likely or unlikely to benefit from MDT, we performed a prospective study to gain more insight in patient and wound characteristics influencing outcome. PATIENTS AND METHODS In the period between August 2002 and December 2005, patients with infected wounds with signs of gangrenous or necrotic tissue who seemed suited for MDT were enrolled in the present study. In total, 101 patients with 117 ulcers were treated. Most wounds were worst-case scenarios, in which maggot therapy was a treatment of last resort. RESULTS In total, 72 patients (71%) were classified as ASA III or IV. In total, 78 of 116 wounds (67%) had a successful outcome. These wounds healed completely (n = 60), healed almost completely (n = 12) or were clean at least (n = 6) at last follow-up. These results seem to be in line with those in the literature. All wounds with a traumatic origin (n = 24) healed completely. All wounds with septic arthritis (n = 13), however, failed to heal and led in half of these cases to a major amputation. According to a multivariate analysis, chronic limb ischaemia (odds ratio [OR], 7.5), the depth of the wound (OR, 14.0), and older age (≥ 60 years; OR, 7.3) negatively influenced outcome. Outcome was not influenced by gender, obesity, diabetes mellitus, smoking, ASAclassification, location of the wound, wound size or wound duration. CONCLUSIONS Some patient characteristics (i.e. gender, obesity, smoking behaviour, presence of diabetes mellitus and ASA-classification at presentation) and some wound characteristics (i.e. location of the wound, wound duration and size) do not seem to contra-indicate eligibility for MDT. However, older patients and patients with chronic limb ischaemia or deep wounds are less likely to benefit from MDT. Septic arthritis does not seem to be a good indication for MDT. PMID:18201474

Although sensory reinnervation occurs after injury in the PNS, poor reinnervation in the elderly and those with diabetes often leads to pathology. Here we quantify subbasal axon density in the central and peripheral mouse cornea over time after three different types of injury. The mouse cornea is highly innervated with a dense array of subbasal nerves that form a spiral called the vortex at the corneal center or apex; these nerves are readily detected within flat mounted corneas. After anesthesia, corneal epithelial cells were removed using either a dulled blade or a rotating burr within an area demarcated centrally with a 1.5 mm trephine. A third wound type, superficial trephination, involved demarcating the area with the 1.5 mm trephine but not removing cells. By 7d after superficial trephination, subbasal axon density returns to control levels; by 28d the vortex reforms. Although axon density is similar to control 14d after dulled blade and rotating burr wounding, defects in axon morphology at the corneal apex remain. After 14d, axons retract from the center leaving the subbasal axon density reduced by 37.2% and 36.8% at 28d after dulled blade and rotating burr wounding, respectively, compared to control. Assessment of inflammation using flow cytometry shows that persistent inflammation is not a factor in the incomplete reinnervation. Expression of mRNAs encoding 22 regeneration associated genes (RAGs) involved in axon targeting assessed by QPCR reveals that netrin-1 and ephrin signaling are altered after wounding. Subpopulations of corneal epithelial basal cells at the corneal apex stop expressing ki67 as early as 7d after injury and by 14d and 28d after wounding, many of these basal cells undergo apoptosis and die. While subbasal axons are restored to their normal density and morphology after superficial trephination, subbasal axon recovery is partial after debridement wounds. The increase in corneal epithelial basal cell apoptosis at the apex observed at 14d after corneal debridement may destabilize newly reinnervated subbasal axons and lead to their retraction towards the periphery.

Ankle sprains in adolescents usually resolve with conservative management but a few patients may develop ankle impingement syndrome. There have been adult studies addressing surgical treatment of this pathology, but our study evaluated the surgical management of anterolateral ankle impingement in adolescents by comparing their outcomes after nonoperative treatment and subsequent surgical intervention. Thirteen patients (children and adolescents) diagnosed with ankle impingement by history, physical examination, and magnetic resonance imaging during a 9-year period at our institution underwent eventual arthroscopic debridement. A retrospective chart review of these patients was performed and they were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) functional rating scale on 3 separate occasions: (1) initial presentation, (2) termination of nonoperative management, and (3) final postoperative follow-up visit. Thirteen adolescents (11 girls and 2 boys; 14 ankles) with a mean age of 15.6 (11.9-18.3) years met the inclusion criteria; of these, all had arthroscopic surgery. Mean duration of reported symptoms was 9.6 (4-15) months and mean duration of nonoperative management (physical therapy, activity modifications) was 6.9 (2-12) months. The mean AOFAS rating (out of 100 total) at initial presentation was 68.4 (40-84) and after nonoperative management was no better with a mean of 68.2 (63-76). The mean AOFAS rating at final follow-up was 90.6 (52-100), which was statistically significant (P

Management of Chronic Pressure Ulcers

Executive Summary In April 2008, the Medical Advisory Secretariat began an evidence-based review of the literature concerning pressure ulcers. Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/tech/tech_mn.html to review these titles that are currently available within the Pressure Ulcers series. Pressure ulcer prevention: an evidence based analysis The cost-effectiveness of prevention strategies for pressure ulcers in long-term care homes in Ontario: projections of the Ontario Pressure Ulcer Model (field evaluation) Management of chronic pressure ulcers: an evidence-based analysis Objective The Medical Advisory Secretariat (MAS) conducted a systematic review on interventions used to treat pressure ulcers in order to answer the following questions: Do currently available interventions for the treatment of pressure ulcers increase the healing rate of pressure ulcers compared with standard care, a placebo, or other similar interventions? Within each category of intervention, which one is most effective in promoting the healing of existing pressure ulcers? Background A pressure ulcer is a localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in conjunction with shear and/or friction. Many areas of the body, especially the sacrum and the heel, are prone to the development of pressure ulcers. People with impaired mobility (e.g., stroke or spinal cord injury patients) are most vulnerable to pressure ulcers. Other factors that predispose people to pressure ulcer formation are poor nutrition, poor sensation, urinary and fecal incontinence, and poor overall physical and mental health. The prevalence of pressure ulcers in Ontario has been estimated to range from a median of 22.1% in community settings to a median of 29.9% in nonacute care facilities. Pressure ulcers have been shown to increase the risk of mortality among geriatric patients by as much as 400%, to increase the frequency and duration of hospitalization, and to decrease the quality of life of affected patients. The cost of treating pressure ulcers has been estimated at approximately $9,000 (Cdn) per patient per month in the community setting. Considering the high prevalence of pressure ulcers in the Ontario health care system, the total cost of treating pressure ulcers is substantial. Technology Wounds normally heal in 3 phases (inflammatory phase, a proliferative phase of new tissue and matrix formation, and a remodelling phase). However, pressure ulcers often fail to progress past the inflammatory stage. Current practice for treating pressure ulcers includes treating the underlying causes, debridement to remove necrotic tissues and contaminated tissues, dressings to provide a moist wound environment and to manage exudates, devices and frequent turning of patients to provide pressure relief, topical applications of biologic agents, and nutritional support to correct nutritional deficiencies. A variety of adjunctive physical therapies are also in use. Method Health technology assessment databases and medical databases were searched from 1996 (Medline), 1980 (EMBASE), and 1982 (CINAHL) systematically up to March 2008 to identify randomized controlled trials (RCTs) on the following treatments of pressure ulcers: cleansing, debridement, dressings, biological therapies, pressure-relieving devices, physical therapies, nutritional therapies, and multidisciplinary wound care teams. Full literature search strategies are reported in appendix 1. English-language studies in previous systematic reviews and studies published since the last systematic review were included if they had more than 10 subjects, were randomized, and provided objective outcome measures on the healing of pressure ulcers. In the absence of RCTs, studies of the highest level of evidence available were included. Studies on wounds other than pressure ulcers and on surgical treatment of pressure ulcers were excluded. A total of 18 systematic reviews, 104 RCTs, and 4 observational studies were included in this review. Data were extracted from studies using standardized forms. The quality of individual studies was assessed based on adequacy of randomization, concealment of treatment allocation, comparability of groups, blinded assessment, and intention-to-treat analysis. Meta-analysis to estimate the relative risk (RR) or weighted mean difference (WMD) for measures of healing was performed when appropriate. A descriptive synthesis was provided where pooled analysis was not appropriate or not feasible. The quality of the overall evidence on each intervention was assessed using the grading of recommendations assessment, development, and evaluation (GRADE) criteria. Findings Findings from the analysis of the included studies are summarized below: Cleansing There is no good trial evidence to support the use of any particular wound cleansing solution or technique for pressure ulcers. Debridement There was no evidence that debridement using collagenase, dextranomer, cadexomer iodine, or maggots significantly improved complete healing compared with placebo. There were no statistically significant differences between enzymatic or mechanical debridement agents with the following exceptions: Papain urea resulted in better debridement than collagenase. Calcium alginate resulted in a greater reduction in ulcer size compared to dextranomer. Adding streptokinase/streptodornase to hydrogel resulted in faster debridement. Maggot debridement resulted in more complete debridement than conventional treatment. There is limited evidence on the healing effects of debridement devices. Dressings Hydrocolloid dressing was associated with almost three-times more complete healing compared with saline gauze. There is evidence that hydrogel and hydropolymer may be associated with 50% to 70% more complete healing of pressure ulcers than hydrocolloid dressing. No statistically significant differences in complete healing were detected among other modern dressings. There is evidence that polyurethane foam dressings and hydrocellular dressings are more absorbent and easier to remove than hydrocolloid dressings in ulcers with moderate to high exudates. In deeper ulcers (stage III and IV), the use of alginate with hydrocolloid resulted in significantly greater reduction in the size of the ulcers compared to hydrocolloid alone. Studies on sustained silver-releasing dressing demonstrated a tendency for reducing the risk of infection and promoting faster healing, but the sample sizes were too small for statistical analysis or for drawing conclusions. Biological Therapies The efficacy of platelet-derived growth factors (PDGFs), fibroblast growth factor, and granulocyte-macrophage colony stimulating factor in improving complete healing of chronic pressure ulcers has not been established. Presently only Regranex, a recombinant PDGF, has been approved by Health Canada and only for treatment of diabetic ulcers in the lower extremities. A March 2008 US Food and Drug Administration (FDA) communication reported increased deaths from cancers in people given three or more prescriptions for Regranex. Limited low-quality evidence on skin matrix and engineered skin equivalent suggests a potential role for these products in healing refractory advanced chronic pressure ulcers, but the evidence is insufficient to draw a conclusion. Adjunctive Physical Therapy There is evidence that electrical stimulation may result in a significantly greater reduction in the surface area and more complete healing of stage II to IV ulcers compared with sham therapy. No conclusion on the efficacy of electrotherapy can be drawn because of significant statistical heterogeneity, small sample sizes, and methodological flaws. The efficacy of other adjunctive physical therapies [electromagnetic therapy, low-level laser (LLL) therapy, ultrasound therapy, ultraviolet light therapy, and negative pressure therapy] in improving complete closure of pressure ulcers has not been established. Nutrition Therapy Supplementation with 15 grams of hydrolyzed protein 3 times daily did not affect complete healing but resulted in a 2-fold improvement in Pressure Ulcer Scale for Healing (PUSH) score compared with placebo. Supplementation with 200 mg of zinc three times per day did not have any significant impact on the healing of pressure ulcers compared with a placebo. Supplementation of 500 mg ascorbic acid twice daily was associated with a significantly greater decrease in the size of the ulcer compared with a placebo but did not have any significant impact on healing when compared with supplementation of 10 mg ascorbic acid three times daily. A very high protein tube feeding (25% of energy as protein) resulted in a greater reduction in ulcer area in institutionalized tube-fed patients compared with a high protein tube feeding (16% of energy as protein). Multinutrient supplements that contain zinc, arginine, and vitamin C were associated with a greater reduction in the area of the ulcers compared with standard hospital diet or to a standard supplement without zinc, arginine, or vitamin C. Firm conclusions cannot be drawn because of methodological flaws and small sample sizes. Multidisciplinary Wound Care Teams The only RCT suggests that multidisciplinary wound care teams may significantly improve healing in the acute care setting in 8 weeks and may significantly shorten the length of hospitalization. However, since only an abstract is available, study biases cannot be assessed and no conclusions can be drawn on the quality of this evidence. PMID:23074533

We present the first reported case of Aspergillus vertebral osteomyelitis and epidural abscess in Singapore in a 50-year-old man with post-tuberculous bronchiectasis. The patient presented with acute urinary retention and flaccid paraplegia. Despite surgical debridement and treatment with voriconazole, the patient developed multiorgan failure and died two weeks after presentation. Early diagnosis and prompt initiation of treatment are emphasised in the hope of improving the outcome of this aggressive condition.

We present 3 consecutive cases of fishbone perforation of the esophagus that resulted in acute mediastinitis. All patients were successfully managed with drainage and debridement of the mediastinum and pleural cavity. However, temporary exclusion with external ligation of the esophagus was also performed in one patient, with spontaneous recanalization two weeks later. We discuss the possible role of this surgical maneuver in the management of esophageal perforation.

Osteochondritis dissecans (OCD) is a joint disorder that affects the articular cartilage and subchondral bone, most commonly at the knee. OCD of the sacroiliac joint is extremely rare. Management of OCD remains controversial, and surgery is often needed, especially when conservative treatment fails. We present a rare case of OCD involving the left sacroiliac joint successfully treated by percutaneous computed tomography-guided retrograde drilling and debridement.

Fungal otomastoiditis is a rare disease, but can be fatal for immunocompromised patients. Recently, there have been increasing cases of otologic infection caused by Candida auris. Candida auris can be easily misdiagnosed for other species and treatment is difficult due to multidrug resistance. Clinician should be aware of this rare pathogen, and it should be treated with appropriate antifungal agent with surgical debridement. © 2017 Blackwell Verlag GmbH.

Microorganisms play a major role in initiation and perpetuation of pulpal and periapical diseases. Therefore, elimination of the microorganisms present in the root canal system is the fundamental objective of endodontic treatment. The use of mechanical debridement, chemical irrigation or other antimicrobial protocols and intra-canal medicaments are critical to attain this goal. The aim of this article was to review the antimicrobial agents and their properties in endodontics. PMID:25031587

Wound bed preparation (WBP) is an integral part of the care programme for chronic wounds. The acronym TIME is used in the context of WBP and describes four barriers to healing in chronic wounds; namely, dead Tissue, Infection and inflammation, Moisture imbalance and a non-migrating Edge. Larval debridement therapy (LDT) stems from observations that larvae of the blowfly Lucilia sericata clean wounds of debris. Subsequent clinical studies have proven debriding efficacy, which is likely to occur as a result of enzymatically active alimentary products released by the insect. The antimicrobial, anti-inflammatory and wound healing activities of LDT have also been investigated, predominantly in a pre-clinical context. This review summarises the findings of investigations into the molecular mechanisms of LDT and places these in context with the clinical concept of WBP and TIME. It is clear from these findings that biotherapy with L. sericata conforms with TIME, through the enzymatic removal of dead tissue and its associated biofilm, coupled with the secretion of defined antimicrobial peptides. This biotherapeutic impact on the wound serves to reduce inflammation, with an associated capacity for an indirect effect on moisture imbalance. Furthermore, larval serine proteinases have the capacity to alter fibroblast behaviour in a manner conducive to the formation of granulation tissue. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

The Accessory Postero-Lateral (AccPL) portal has recently been described to improve the visualisation for the endoscopic debridement of Haglund's tubercle. The safety of using this portal has been considered previously for posterior ankle arthroscopy. We performed a study to determine the proximity of the AccPL portal to the sural nerve. We compared the distances between AccPL and PL portals to the sural nerve in 17 cadaveric specimens. The AccPL portal was significantly closer (mean 12.0mm, range 6-19 mm, SD=3.64) to the sural nerve than the PL portal (mean 14.1mm, range 11-18 mm, SD=2.34) (t(16)=-2.34, p=0.03). In two cases the sural nerve was in contact with the clip but on close inspection, the nerve had not been damaged in any of the specimens. We conclude that the AccPL portal is a safe method to allow visualisation during endoscopic debridement of the Achilles tendon insertion. We also recommend that the portal is used for visualisation rather than instrumentation. Copyright © 2011 European Foot and Ankle Society. Published by Elsevier Ltd. All rights reserved.

Onychomycosis Diagnosis and Management: Perspectives from a Joint Dermatology-Podiatry Roundtable.

Onychomycosis prevalence is expected to rise as the population ages and the prevalence of diabetes, peripheral vascular disease, and other significant risk factors rise. Until recently, treatment options were limited due to safety concerns with oral antifungals and low efficacy with available topical agents. Efinaconzole and tavaborole were approved by the FDA in 2014 for onychomycosis treatment and provide additional effective topical treatment options for patients with mild-to-moderate disease. Dermatologists and podiatrists both regularly treat onychomycosis, yet there are striking differences between specialties in approach to diagnosis and treatment. In order to explore these differences a joint dermatology-podiatry roundtable of onychomycosis experts was convened. Although it has little effect on mycologic cure, debridement may be a valuable adjunct to oral or topical antifungal therapy, especially in patients with greater symptom burden. However, few dermatologists incorporate debridement into their treatment plans and referral to podiatry may be appropriate for some of these patients. Furthermore, podiatrists may be better equipped to manage patients with concurrent diabetes or peripheral vascular disease and elderly patients who are unable to maintain proper foot hygiene. Once cure is achieved, lifestyle and hygiene practices, maintenance/prophylactic onychomycosis treatment, and proactive tinea pedis treatment in patients and family members may help to maintain patients' cured status.

Advances in the local and targeted delivery of anti-infective agents for management of osteomyelitis.

PubMed

Ford, Caleb A; Cassat, James E

2017-09-01

Osteomyelitis, a common and debilitating invasive infection of bone, is a frequent complication following orthopedic surgery and causes pathologic destruction of skeletal tissues. Bone destruction during osteomyelitis results in necrotic tissue, which is poorly penetrated by antibiotics and can serve as a nidus for relapsing infection. Osteomyelitis therefore frequently necessitates surgical debridement procedures, which provide a unique opportunity for targeted delivery of antimicrobial and adjunctive therapies. Areas covered: Following surgical debridement, tissue voids require implanted materials to facilitate the healing process. Antibiotic-loaded, non-biodegradable implants have been the standard of care. However, a new generation of biodegradable, osteoconductive materials are being developed. Additionally, in the face of widespread antimicrobial resistance, alternative therapies to traditional antibiotic regimens are being investigated, including bone targeting compounds, antimicrobial surface modifications of orthopedic implants, and anti-virulence strategies. Expert commentary: Recent advances in biodegradable drug delivery scaffolds make this technology an attractive alternative to traditional techniques for orthopedic infection that require secondary operations for removal. Advances in novel treatment methods are expanding the arsenal of viable antimicrobial treatment strategies in the face of widespread drug resistance. Despite a need for large scale clinical investigations, these strategies offer hope for future treatment of this difficult invasive disease.

Necrotizing fasciitis (NF) is a rapidly progressive disease that requires urgent surgical debridement for survival. Interhospital transfer (IT) may be associated with delay to operation, which could increase mortality. We hypothesized that mortality would be higher in patients undergoing surgical debridement for necrotizing fasciitis after IT compared to Emergency Department (ED) admission. We performed a retrospective cohort analysis from 2000-2006 using the Nationwide Inpatient Sample. Inclusion criteria were age >18 years, primary diagnosis of NF, and surgical therapy within 72 hours of admission. Logistic regression was used to assess the relationship between admission source, patient and hospital variables, and mortality. We identified 9,958 cases over the study period. Patients in the ED group were more likely to be nonwhite and of lower income when compared with patients in the IT group. Unadjusted mortality was higher in the IT group than ED group (15.5% vs 8.7%, P < .001). After adjusting for potential confounders, odds of mortality were still greater in the IT (OR 2.04, CI 95% 1.60-2.59, P < .001). Interhospital transfer is associated with increased risk of in-hospital mortality after surgical therapy for NF, a finding which persists after controlling for patient and hospital level variables.

2017-12-01

Fournier's gangrene is a gas-forming, necrotising soft tissue infection affecting the perineum. It spreads rapidly along the deep fascial planes and is associated with a high mortality rate. With a growing elderly population with comorbidities, the frequency of severe cases of Fournier's gangrene is expected to increase. We retrospectively reviewed 20 patients diagnosed with Fournier's gangrene at our institution from 2003 to 2014 and analysed data. Thirteen patients had diabetes mellitus, two had been diagnosed with liver cirrhosis, and four were chronic alcoholics. Of 15 patients admitted to an intensive care unit, 11 underwent colostomy, and 4 required skin grafts for wound healing. The wide wounds of two patients were healed using vacuum-assisted closure (VAC ® ) dressing without additional surgery. The mortality rate was 25%, and the patients whose Fournier's gangrene severity index (FGSI) score was higher than 9 points or whose blood urea nitrogen (BUN) level was higher than 50 mg/dl had a poor prognosis. In order to treat Fournier's gangrene, aggressive surgical treatment, including wide debridement and stoma creation, should be considered as soon as possible to improve survival rates. Additionally, VAC dressing is helpful in healing the wide debridement wound without additional reconstructive surgery. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Wound outcome in combat injuries is associated with a unique set of protein biomarkers

PubMed Central

2013-01-01

Background The ability to forecast whether a wound will heal after closure without further debridement(s), would provide substantial benefits to patients with severe extremity trauma. Methods Wound effluent is a readily available material which can be collected without disturbing healthy tissue. For analysis of potential host response biomarkers, forty four serial combat wound effluent samples from 19 patients with either healing or failing traumatic- and other combat-related wounds were examined by 2-D DIGE. Spot map patterns were correlated to eventual wound outcome (healed or wound failure) and analyzed using DeCyder 7.0 and differential proteins identified via LC-MS/MS. Results This approach identified 52 protein spots that were differentially expressed and thus represent candidate biomarkers for this clinical application. Many of these proteins are intimately involved in inflammatory and immune responses. Furthermore, discriminate analysis further refined the 52 differential protein spots to a smaller subset of which successfully differentiate between wounds that will heal and those that will fail and require further surgical intervention with greater than 83% accuracy. Conclusion These results suggest candidates for a panel of protein biomarkers that may aid traumatic wound care prognosis and treatment. We recommend that this strategy be refined, and then externally validated, in future studies of traumatic wounds. PMID:24192341

The need for improved wound care is receiving considerable attention in the Islamic Republic of Iran. Beginning in 2003, maggot therapy (MT) became part of Iran's effort to advance its wound care technology. The first cohort of patients treated with MT was analysed to evaluate the use of this treatment. Patients treated with MT at three hospitals in Tehran were analysed retrospectively. Primary outcomes were time to wound debridement and time to wound healing. Factors potentially influencing primary outcomes were also recorded, including demographic factors (such as age, race, gender), wound characteristics, underlying medical illnesses, and treatment attitudes. We analysed 28 patients with 29 wounds. Most (55%) of the wounds were ischaemic, neuropathic or mixed-pathology foot ulcers in patients with diabetes. Half were considered unsalvageable. All were completely debrided and subsequently healed with MT, without amputation, grafts, or advanced interventions. Osteomyelitis was present in all cases before MT, but appeared to have been eradicated, without recurrence during at least three years' follow-up. The most common adverse events were malodour, with wound pain reported in two patients. All patients and therapists were pleased with their overall experience. Maggot therapy can provide advanced wound care even in resource-limited areas. Maggot therapy was very acceptable to the patients and their therapists.

Gas gangrene and related infection: classification, clinical features and aetiology, management and mortality. A report of 88 cases.

The clinical features of gas gangrene and related infection seen in 88 patients over a 10-year period are described. It is suggested that clostridial infection could be simply classified as either 'gas-forming' or 'non-gas-forming'. The gas-forming group represents the more severe form of infection. Non-clostridial gas gangrene may present in a variety of forms. The anaerobic streptococcus was the organism most frequently responsible, but these cases were indistinguishable from clostridial infection on clinical grounds. The treatment of gas gangrene in this series of patients is reported. Emphasis is laid on the importance of adequate prophylaxis with penicillin in patients at risk. The value of antibiotics in established infection remains equivocal. The evidence supporting the value of hyperbaric oxygen therapy is assessed and an attempt made to quantify the response to this treatment. Benefit was apparent in only a proportion of patients. A favourable response indicated clostridial infection and guaranteed immediate survival. Extensive debridement or amputation is unnecessary in this group. No response following hyperbaric oxygen therapy indicated widespread mixed clostridial and non-clostridial infection, or infection due to organisms other than clostridia. Urgent and extensive debridement and amputation remain the predominant measures in this group.

2002-10-01

A retrospective study was performed in 26 patients who underwent an operation for femoro-patellar pain due to a patellar chondromalacia with or without minor patellar dislocation/lateral pressure syndrome. The average age of the patients was 28.5 (15-39) years. 22 of the 26 patients revealed minor chondral damages of the stages 1 and 2 according to Outerbridge. In 12 patients ("lavage" group), an arthroscopic joint debridement only was carried out, while an additional open, lateral retinaculum release was made in 14 patients ("lateral release" group). The patella's distance of dislocation according to Hepp was reduced on an average of 3.0 (0-7) mm (p = 0.0019). The results of Bentley's score obtained during the follow-up interval on an average of 30.1 (9 to 60) months were almost identical for both groups. "Good" and "very good" results were achieved in the "lavage" group (83.3 %) and "lateral release" group (78.6 % of the patients). Lateral release should be used in cases of patellar decentration between 5 and 10 mm and adequate pain symptoms. The post-operative distance of dislocation should be less than 5 mm. Under such conditions and with minor chondral damage, a combined approach by using an arthroscopic joint debridement and open lateral release is promising to treat a patellar dislocation/lateral pressure syndrome.

Aim To evaluate long-term clinical response to periodontal therapy and maintenance in localized aggressive periodontitis (LAP). Materials and Methods One hundred forty-one African-Americans diagnosed with LAP, aged 5–25 years, were enrolled. Patients underwent periodontal mechanical debridement plus one week of amoxicillin/metronidazole. Mechanical therapy was repeated as needed and clinical parameters were recorded at baseline, 3, 6, 12, 18, and 24 months, and 2 additional annual follow-up visits after treatment. Radiographs from primary dentition of patients with LAP in permanent dentition, and additional healthy siblings (HS) were analyzed retrospectively. Results Periodontal therapy significantly improved probing depth and clinical attachment level up to 4 years (mean reductions: 2.18 ± 1.03 and 2.80 ± 1.43 mm, respectively). Percentage of affected sites was reduced at all timepoints and maintained up to 4 years. Noncompliance with antibiotics/appointments negatively affected the treatment response. Ninety percent of LAP patients in permanent dentition and 32% of HS presented radiographic bone loss in primary dentition. Conclusions Mechanical debridement with one-week of systemic antibiotics along with proper periodontal maintenance was effective in the treatment and successful maintenance of LAP for up to 4 years. LAP in permanent dentition may be preceded in the primary dentition. Clinicaltrials.gov #NCT01330719. PMID:27767222

2013-01-01

We report the successful arthroscopic treatment of a case of subcalcaneal bursitis with plantar fasciitis. To our knowledge, this is the first report on arthroscopic excision of a subcalcaneal bursa. Right heel pain developed in a 50-year-old woman, without any obvious cause. She reported that the heel pain occurred immediately after waking and that the heel ached when she walked. Magnetic resonance imaging showed an extra-articular, homogeneous, high-intensity lesion in the fat pad adjacent to the calcaneal tubercle on T2-weighted sagittal and coronal images and thickening of the plantar fascia on T2-weighted sagittal images. A diagnosis of a recalcitrant subcalcaneal bursitis with plantar fasciitis was made, and surgery was performed. The arthroscope was placed between the calcaneus and the plantar fascia. With the surgeon viewing from the lateral portal and working from the medial portal, the dorsal surface of the degenerative plantar fascia was debrided and the medial half of the plantar fascia was released, followed by debridement of the subcalcaneal bursal cavity through the incised plantar fascia. Full weight bearing and gait were allowed immediately after the operation. At the latest follow-up, the patient had achieved complete resolution of heel pain without a recurrence of the mass, confirmed by magnetic resonance imaging. PMID:23875139

Background: Power lifting places the shoulder complex at risk for injury. Microfracture is a relatively new procedure for chondral defects of the glenohumeral joint and is not well described in the literature. Objectives: The purpose of this case report is to describe the post-operative rehabilitation used with a power lifter who underwent a microfracture procedure to address glenoid and humeral chondral defects, debridement of type I superior labral anterior-posterior lesion, and a subacromial decompression. Case Description: The patient was a 46 year-old male who was evaluated nine weeks status-post arthroscopic microfracture procedure for glenoid and humeral chondral defects, debridement of superior labral anterior-posterior (SLAP) lesion, and subacromial decompression. Rehabilitation consisted of postural education, manual therapy, rotator cuff and scapular strengthening, dynamic stabilization, weightbearing exercises, and weight training over nine weeks (24 sessions). Lifting modifications were addressed. Outcomes: Results of the QuickDASH indicate that activities of daily living (ADLs), work, and sports modules all improved significantly, and the patient was able to return to recreational power lifting with limited discomfort or restrictions. Discussion: A structured post-operative physical therapy treatment program allowed this patient to return to recreational power lifting while restoring independent function for work-related activities and ADLs.

Contemporary Evaluation and Management of the Diabetic Foot

PubMed Central

Sumpio, Bauer E.

2012-01-01

Foot problems in patients with diabetes remain a major public health issue and are the commonest reason for hospitalization of patients with diabetes with prevalence as high as 25%. Ulcers are breaks in the dermal barrier with subsequent erosion of underlying subcutaneous tissue that may extend to muscle and bone, and superimposed infection is a frequent and costly complication. The pathophysiology of diabetic foot disease is multifactorial and includes neuropathy, infection, ischemia, and abnormal foot structure and biomechanics. Early recognition of the etiology of these foot lesions is essential for good functional outcome. Managing the diabetic foot is a complex clinical problem requiring a multidisciplinary collaboration of health care workers to achieve limb salvage. Adequate off-loading, frequent debridement, moist wound care, treatment of infection, and revascularization of ischemic limbs are the mainstays of therapy. Even when properly managed, some of the foot ulcers do not heal and are arrested in a state of chronic inflammation. These wounds can frequently benefit from various adjuvants, such as aggressive debridement, growth factors, bioactive skin equivalents, and negative pressure wound therapy. While these, increasingly expensive, therapies have shown promising results in clinical trials, the results have yet to be translated into widespread clinical practice leaving a huge scope for further research in this field.

We studied the outcome in culture-positive and culture-negative infected total knee arthroplasty (TKA). We retrospectively reviewed 140 patients with culture-positive and 102 patients with culture-negative infected TKAs. We determined the infection control rate and clinical outcome after repeated debridement, and repeated 2-stage TKA in the culture-positive and culture-negative groups. The mean follow-up was 9.3 years (range 5-14 years) in the culture-positive group and 10.6 years (5-22) in the culture-negative group. The overall infection control rate was 56 % in both groups after the first treatment. The overall infection control rate was 90 % in the culture-positive group and 95 % in the culture-negative group. A functional knee was obtained in 90 % in the culture-positive group and 95 % in the culture-negative group. The data suggest that treatment according to the types of infection in both culture-positive and culture-negative groups after TKA controlled infection and maintained functional TKA with a firm level of fixation for most patients. Repeated debridement and repeated two-stage exchange TKA further improved infection control rates after the initial treatment and increased the likelihood of maintaining a functional TKA.

Recurrent corneal erosions are painful and put patients' vision at risk. Treatment typically begins with debridement of the area around the erosion site followed by more aggressive treatments. An in vivo mouse model has been developed that reproducibly induces recurrent epithelial erosions in wild-type mice spontaneously within two weeks after a single 1.5 mm corneal debridement wound created using a dulled-blade. This study was conducted to determine whether 1) inhibiting MMP9 function during healing after dulled-blade wounding impacts erosion development and 2) wounds made with a rotating-burr heal without erosions. Oral or topical inhibition of MMPs after dulled-blade wounding does not improve healing. Wounds made by rotating-burr heal with significantly fewer erosions than dulled-blade wounds. The localization of MMP9, β4 integrin and basement membrane proteins (LN332 and type VII collagen), immune cell influx, and reinnervation of the corneal nerves were compared after both wound types. Rotating-burr wounds remove the anterior basement membrane centrally but not at the periphery near the wound margin, induce more apoptosis of corneal stromal cells, and damage more stromal nerve fibers. Despite the fact that rotating-burr wounds do more damage to the cornea, fewer immune cells are recruited and significantly more wounds resolve completely. Copyright © 2011 Elsevier Ltd.

Management of aortic graft infections - the present strategy and future perspectives.

PubMed

Treska, V; Certik, B; Molacek, J

2016-01-01

Aortic graft infections (AGI) are serious complications of open and endovascular types of surgery with an incidence rate of 0.6-3 %. AGI are associated with 30-60 % perioperative mortality and 40-60 % morbidity rate with limb amputation rates between 10 % and 40 %. The economic cost of AGI is substantial. At the time of aortic reconstruction, almost 90 % of patients have one or more predisposing factors for AGI. The diagnosis is based on clinical symptomatology, laboratory markers, microbial cultures, and imaging modalities. The general principle of surgical treatment lies in the removal of infected graft, debridement of infected periprosthetic tissues, and vascular reconstruction by in situ or extra-anatomic bypass with long-term antibiotic therapy. The conservative treatment is used only for selected patients with endograft infection. This review summarizes the current knowledge about the incidence, predisposing factors, etiology, diagnosis, treatment options, and prevention of aortic vascular graft and endograft infections. With the growing number of endovascular procedures we can expect more cases of infected aortic endografts in patients with severe comorbidities in the near future, where the recent radical surgical approach (graft excision, debridement, and new revascularization) cannot be used. Therefore the less invasive, sophisticated and individualized treatment strategies will have to be used in search of the best therapeutic approach to each specific patient (Fig. 4, Ref. 82).

Aim To extend the microfracture procedure, which has been proven successful on osteochondritis dissecans (OCD) lesions in the knee and ankle, to OCD lesions in the elbow. Methods Nine young patients were treated by arthroscopic debridement and microfracture by a single surgeon. The average age at operation was 15.0 years (median 15; range 12-19). The average length of the follow-up was 5.3 years (median 5; range 2-9). The follow-up included physical examination and patient interview with elbow function scoring. Success of treatment was determined according to pre-operative and follow-up Mayo Elbow Performance Index scores and the patients’ return to sports. Results Eight patients scored excellent results on the follow-up and 1 scored a good result. Four out of 9 patients were able to increase their training intensity, 2 returned to the same level of activity, 2 changed sports (due to reasons unrelated to the health of their elbow), and 1 left professional sports and started training only recreationally. No patients stopped participating in sports altogether. Conclusions We advocate arthroscopic microfracturing, followed by a strict rehabilitation regime, as a highly effective treatment for OCD of the humeral capitellum. PMID:22351577

Effect of hyperbaric oxygen on the growth and development of medicinal maggots.

Some wound care therapists use both maggot debridement therapy (MDT) and hyperbaric oxygen (HBO2) therapy to treat non-healing wounds. Some practitioners have reported success using both MDT and HBO2 therapy concurrently; others have not. To begin evaluating the utility of using MDT and HBO2 therapy concurrently, we assessed the effects of hyperbaric oxygen (HBO2) on maggot growth and development, as a surrogate for debridement capacity. Replicate sets of medical-grade blowfly larvae were placed on liver-agar wound models and exposed to HBO2 at 2.0 atmospheres absolute (atm abs) for 90 minutes on 0 (control), 1, 2 or 3 sequential days. The effects of HBO2 exposure were quantified by measuring the maggots' subsequent growth and development. Exposure to HBO2 was most lethal to young larvae (second instars), but not to older larvae (third instars). There was no dose-relationship between the number of HBO2 treatments and rate of larval survival. Our findings suggest that maggot therapy and HBO2 therapy may be administered concurrently, as long as the larvae are not too immature (that is, as long as they are beyond the second instar) by the time they take their first dive. A clinical trial evaluating the clinical benefits of concurrent HBO2 therapy and MDT is warranted.

Seventy consecutive patients treated for lawn mower injuries to the foot and ankle were reviewed to determine optimal treatment, functional results, and complications. Injuries were classified into 1 or more functional-anatomical zones (I, digits; II, dorsum; III, plantar nonweight-bearing surface; IV, heel; and V, ankle) for a total of 96 injuries. Thirty-one patients were available for follow-up. Mean age was 36.7 years and 84% were males. Most injuries (67%) involved patients > 16 years old using a push mower; however, 18% involved children < 5 years old, usually caused by riding mowers (70%). Primary closure after adequate irrigation and debridement was the preferred method of treatment except in patients with Zone IV injuries. Antibiotic prophylaxis was used in almost all injuries (93%). A 100% ambulation rate was achieved with 10% of patients requiring a prosthesis. Zone IV (heel) injuries had a 50% complication rate from chronic soft tissue breakdown. The wound infection rate per injury was 12.5% and did not vary significantly between closed (11.4%) and open (17.6%) treatment. Lawn mower injuries to the foot and ankle can be closed primarily after adequate irrigation and debridement without compromise of infection rate or function. Antibiotic prophylaxis is recommended. One-sixth of these injuries involve children < 5 years of age and can be prevented.

The objectives of the study were (1) to look for any local, clinically apparent response, within and around a debrided wound, to a novel biocompatible polyurethane foam during repeated, short-term implantation, and (2) to assess the material's efficacy as a negative pressure wound therapy (NPWT) interface compared with a widely used, commercially available foam. Twenty pressure ulcers in 18 patients underwent surgical debridement, then randomization to receive novel treatment or control foam as the wound interface for NPWT. Dressing changes every 2-3 days allowed qualitative wound assessment and quantitative measurement to compare outcomes. No adverse reaction was observed in any patient receiving the new foam. The new "novel foam" performed as a NPWT interface as effectively as the control "standard foam." In deep wounds, the new foam was easier to remove, fragmented less, and showed less retention than the control foam. No marginal in-growth occurred, making removal less traumatic and reducing bleeding from cavity wall granulations. The results support previous large animal studies, and independent ISO10993 testing, that the new foam is safe and biocompatible. Its efficacy as an NPWT interface, nontraumatic removal with low fragmentation and retention rate, favors the new material, especially in deep cavity wounds. © 2014 by the Wound Healing Society.

The physiological and pathological complexity of the wound healing process makes it more challenging to design an ideal tissue regeneration scaffold. Precise scaffolding with high drug loading efficiency, efficient intracellular efficacy for therapeutic delivery, minimal nonspecific cellular and blood protein binding, and maximum biocompatibility forms the basis for an ideal delivery system. This paper describes a combinational multiphasic delivery system, where biomolecules are delivered through the fabrication of coaxial electrospinning of different biocompatible polymers. The ratio and specificity of polymers for specific biofunction are optimized and the delivery system is completely characterized with reference to the mechanical property and structural integrity of bromelain (debridement enzyme) and salvianolic acid B (pro-angiogenesis and re-epithelialization). The in vitro release profile illustrated the sustained release of debriding protease and bioactive component in a timely fashion. The fabricated scaffold showed angiogenic potential through in vitro migration of endothelial cells and increased new capillaries from the existing blood vessel in response to an in ovo chicken chorioallantoic membrane assay. In addition, in vivo studies confirm the efficacy of the fabricated scaffold. Our results therefore open up a new avenue for designing a bioactive combinational multiphasic delivery system to enhance wound healing.

Accidental Bolt Gun Injury to Femur - A Case Report.

Bolt gun or slaughterer's guns are used in meat industry for "humane killing" of animals. Injuries caused by bolt gun are rare, reported exclusively from central European countries. We report a case of 28 year old male, who accidentally shot himself with a bolt gun to his right thigh. A 28 years old male presented to our Accident and Emergency department after accidental injury to his right thigh with bolt gun. He had an entry wound measuring 2 cm in length and 1 cm in breadth over anterior aspect of lower one third of thigh at lower and sustained Grade II compound fracture of right femur shaft at distal one third. The wound was treated with multiple debridements, negative pressure wound therapy and intravenous antibiotics based on culture and sensitivity. Bolt gun or slaughterer's guns are weapons used in meat industry for slaughtering animals. Wounds inflicted by bolt guns have specific morphological feature, distinctive from wounds made by other kinds of hand firearms. Most of the time wound will be infected at presentation. Lesions caused by these weapons are likely to have a more serious character than is to be expected from the size of the entrance wound. The mainstay of treatment is liberal wound exploration, multiple debridement's and intra venous antibiotics based on culture reports to treat infection and prevent morbidity.

Contemporary evaluation and management of the diabetic foot.

PubMed

Sumpio, Bauer E

2012-01-01

Foot problems in patients with diabetes remain a major public health issue and are the commonest reason for hospitalization of patients with diabetes with prevalence as high as 25%. Ulcers are breaks in the dermal barrier with subsequent erosion of underlying subcutaneous tissue that may extend to muscle and bone, and superimposed infection is a frequent and costly complication. The pathophysiology of diabetic foot disease is multifactorial and includes neuropathy, infection, ischemia, and abnormal foot structure and biomechanics. Early recognition of the etiology of these foot lesions is essential for good functional outcome. Managing the diabetic foot is a complex clinical problem requiring a multidisciplinary collaboration of health care workers to achieve limb salvage. Adequate off-loading, frequent debridement, moist wound care, treatment of infection, and revascularization of ischemic limbs are the mainstays of therapy. Even when properly managed, some of the foot ulcers do not heal and are arrested in a state of chronic inflammation. These wounds can frequently benefit from various adjuvants, such as aggressive debridement, growth factors, bioactive skin equivalents, and negative pressure wound therapy. While these, increasingly expensive, therapies have shown promising results in clinical trials, the results have yet to be translated into widespread clinical practice leaving a huge scope for further research in this field.

To report the case of a 70-year-old woman with Serratia infectious crystalline keratopathy. Case report. This is a report of a 70-year-old woman with a history of chronic open-angle glaucoma and trachoma with lagophthalmos, entropion, and trichiasis in both eyes who developed crystalline keratopathy after penetrating keratoplasty and cataract extraction in the right eye followed up with treatment with long-term topical steroids. Ten months after the initial penetrating keratoplasty and cataract extraction, the patient had decreased visual acuity, intense pain, and tearing in the right eye. Corneal cultures showed Serratia marcescens. Topical steroids were discontinued, and treatment with tobramycin and vancomycin ophthalmic solution every hour was initiated. Despite 1 week of aggressive therapy, there was an increase in corneal infiltrate, epithelial defects, and melting, which eventually involved the peripheral recipient cornea. Therapeutic penetrating keratoplasty, debridement of the peripheral cornea, and amniotic membrane transplantation were performed. Antibiotic agents were used postoperatively. There has been no evidence of recurrent infection. The best-corrected visual acuity improved to 6/15 at the 6-month follow-up period after the second intervention. S. marcescens may cause infectious crystalline keratopathy after penetrating keratoplasty in patients treated with long-term topical steroids. Therapeutic penetrating keratoplasty, surgical debridement, and amniotic membrane transplantation may be necessary when the clinical response to intensive medical treatment is inadequate.

Necrotizing fasciitis is an uncommon soft-tissue infection, associated with high morbidity and mortality. Early recognition and treatment are crucial for survival. Acinetobacter baumannii is rarely associated with necrotizing fasciitis. Wound infections due to A. baumannii have been described in association with severe trauma in soldiers. There are only sporadic reports of monomicrobial A. baumannii necrotizing fasciitis. We report a unique case of monomicrobial necrotizing fasciitis caused by multidrug resistant (MDR) A. baumannii, in absence of any preceding trauma, surgery, or any obvious breech in the continuity of skin or mucosa. A 48-year-old woman with history of HIV, asthma, hypertension, and tobacco and excocaine use presented with acute respiratory failure requiring mechanical ventilation. She was treated for pneumonia for 7 days and was successfully extubated. All septic work-up was negative. Two days later, she developed rapidly spreading nonblanching edema with bleb formation at the lateral aspect of right thigh. Emergent extensive debridement and fasciotomy were performed. Operative findings and histopathology were consistent with necrotizing fasciitis. Despite extensive debridement, she succumbed to septic shock in the next few hours. Blood, wound, and tissue cultures grew A. baumannii, sensitive only to amikacin and polymyxin. Histopathology was consistent with necrotizing fasciitis. PMID:25349748

5 patients with diabetic-foot were treated by maggot therapy. The most serious case was in a 75-year-old man who had gangrene and osteomyelitis of the right foot. Proteus mirabilis, Enterococcus sp., Providencia stuartii and Staphylococcus spec. (coagulase positive) were isolated from lesions which did not respond to antibiotic therapy. The patient had twice refused amputation but agreed to maggot therapy. Larvae of the sheep blowfly Phoenicia (Lucilia) sericata were used for twice-weekly treatment over a period of 7 months. Sterile larvae were applied to the wound and replaced every 3-4 days. After 4 months of treatment, the necrotic tissue around the toes and on the sole of the foot detached from the healthy tissue. During the last 3 months of treatment the larvae removed the remaining infected tissue. As therapy progressed, new layers of healthy tissue covered the wound. The offensive odor associated with the necrotic tissue and the intense pain in the foot decreased significantly. At the end of therapy, during which there were no complaints of discomfort, he was able to walk. In the 4 other patients who had relatively superficial gangrene, the maggots debrided the wounds within 2-4 weeks. Thereafter treatment was continued with antibiotics. Maggot therapy can be recommended in cases of intractable gangrene and osteomyelitis, when treatment with antibiotics and surgical debridement have failed.

Minimal debridement or simple wound closure as the only surgical treatment in war victims with low-velocity penetrating head injuries. Indications and management protocol based upon more than 8 years follow-up of 99 cases from Iran-Iraq conflict.

During military conflicts, surviving victims traditionally underwent large enough craniectomy or craniotomy to achieve extensive debridement of the in-driven bone, shell fragments, and debris. Meanwhile, the completely as well as the partially devitalized adjacent brain tissue would also be debrided. This might have led to additional neurologic deficit or lesser degree of recovery of functions. We studied the efficacy and safety of much more limited or even absence of surgical intervention in a selected group of wartime head-wounded patients. Among 1,150 war victims with penetrating head wounds referred to two major centers affiliated with Tehran University of Medical Sciences during the 8-year period spanning the Iran-Iraq conflict, there were 191 head-wounded patients who underwent either no surgical intervention or a very limited debridement. We have attempted to follow up as closely as possible for more than 8 years. Ninety-nine of them fulfilled the criteria to be included in this series. Close follow-up for development of cerebral infections, functional recovery, or development of new neurologic deficits and epilepsy were performed. At least 3 contrast-enhanced CT scans were taken for each patient. All patients were victims of the battle-field areas with low- to moderate-velocity missile or shell fragment injury. The Glasgow Coma Scale (GCS) scores of the patients were between 8-14 when visited by the first attending neurosurgery staff. The factors considered to be effective in the outcome analysis were the entry point, the number of the in-driven bone fragments, the retained shell fragments, the brain compartments affected, and the paranasal sinus or skull base involvement with or without cerebrospinal fluid (CSF) fistula. There were 13 unilobar, 44 bilobar, 4 trilobar, 38 transventricular, and 3 skull base lesions. The number of retained metal fragments varied between 1 to 6. The number of retained bone fragments varied between 1 to 5 in 73 victims and more than five chips in other cases. The outcome was good (back to work) in 90 patients and poor (severely disabled) in 4. Five patients died because of severity of brain damage and meningitis. The effect of the different enumerated variables upon the outcome was measured using chi(2) and Fisher exact test, which was nonsignificant for all of the variables except for the orbitofacial entry point of injury (p = 0.00006). This study seems to indicate that not only is reoperation for retained bone or shell fragments unnecessary, but surgeons having modern neuroradiological instruments available to detect the proper explanation for changes in GCS of the patients may decide not to proceed with any surgical intervention in a good number of patients. As a result of the "no surgical treatment protocol," one can preserve cerebral tissue without exposing the patient to undue risk of seizures, infection, or death by leaving behind some or all the in-driven bone and shell fragments.

Bioactive borate glass (BG) has good biocompatibility and biodegradation. To investigate the feasibility of bioactive borate glass as a carrier of the antibiotic controlled-releasing by implanting vancomycin-loaded BG (VBG) into the focus of tibia chronic osteomyelitis after debridement. VBG and vancomycin-loaded calcium sulfate (VCS) were prepared with a vancomycin content of 80 mg/g. Sixty-five New Zealand white rabbits, weighing 2.12-3.91 kg (mean, 2.65 kg), were used. The tibia chronic osteomyelitis rabbit models were established by injecting methicillin-resistant Staphylococcus aureus (MRSA, 0.1 mL, 1 x 10(9) cfu/mL) into the right tibia of 65 rabbits. After 3 weeks of injection, 54 rabbits of successful models were randomly divided into groups A (n=11), B (n=11), C (n=16), and D (n=16). Simple debridement was performed in group A; BG, VCS, and VBG were implanted into the infection sites of groups B, C, and D respectively after thorough debridement. A sample of the debrided tissues was harvested for bacterial examination. The vancomycin serum levels were determined in groups C and D at 1, 2, 4, 10, 24, and 48 hours after operation. The boron serum levels were determined in groups B and D at 10, 24, 48, 72, and 120 hours after operation. After 8 weeks, the effectiveness was assessed radiographically, bacteriologically, and histopathologically. Ten rabbits died after operation. No vancomycin was detected in group C; the vancomycin level increased gradually, reached the highest level at 4 hours after operation, and then decreased rapidly in group D. No boron was detected in group B; the boron reached the highest serum level at 10 hours after operation, and then decreased gradually in group D. At 8 weeks, calcium sulfate degraded in group C; BG degraded partially in group D; and no obvious degradation was observed in group B. The repair effect was better in group D than in group C. There was no significant difference in radiograph scoring between groups A, B, C and D (P > 0.05) before operation, but there was significant difference between group D and groups A, B, C (P < 0.05) at 8 weeks after operation. The bacterial culture showed that all the MRSA results were positive in 4 groups. At 8 weeks, the negative rates of MRSA examination were 36.36%, 18.18%, 73.33%, and 81.25% respectively in groups A, B, C, and D, showing significant differences between group D and groups A, B (P < 0.05). The histopathological observation showed that a large number of new bones formed and no foreign body reaction occurred in group D. The histopathologic scores of groups A, B, C, and D were 6.45 +/- 3.62, 7.55 +/- 3.36, 4.27 +/- 2.91, and 3.81 +/- 3.04 respectively, showing significant differences between group D and groups A, B, and between group C and group B (P < 0.05). VBG can improve the repair of bone defect in the treatment of chronic osteomyelitis.

Endodontic therapy is predictable and successful only to the extent that the root canal system can be debrided, disinfected and sealed against future contamination. In order to accomplish these goals it is necessary to become familiar with the variability of the system we seek to treat.

Diabetes foot ulceration (DFU) has a negative impact on the quality of life and leads to disabling morbidity, such as lower extremity amputation (LEA). This study aimed to evaluate the LEA trend before and after the establishment of the diabetes foot team, an on-time debridement, on-site screening, and multidisciplinary integration with standardizing care, in Chang Gung Memorial Hospital, Chia Yi, Taiwan, starting in 2010. The study retrospectively investigated the non-traumatic LEA rate in diabetes foot (identified by using ICD-9-Clinical Modification (CM) codes, 250.70-250.83) and whole patients with diabetes (ICD-9 250.XX) yearly from 2004 to 2013. Patients were enrolled from hospitalization, emergency room (ER), or outpatient departments, respectively. Despite the overall incidence of diabetes foot in patients with diabetes remaining constant, from 3.47% in 2004 to 3.58% in 2013, the incidence of hospitalized diabetes foot from diabetes reduced, from 2.83% in 2004 to 1.51% in 2013. Introduction of integrated wound care also led to a reduction of the average LEA rate in hospitalized patients, from 15.27% (2004-2009) to 6.08% (2010-2013) (P<0.001). A similar decline of the LEA rate was observed for patients from hospitalization, ER and outpatient departments together with an average LEA rate from 7.99% (2004-2009) down to 3.02% (2010-2013) (P<0.001). In trend analysis, the curve estimation revealed a quadratic trend in the relationship between LEA rate and time (R-square=0.869, P=0.001) for hospitalized patients as well as a linear (R-square=0.819, P<0.001) and quadratic (R-square=0.845, P=0.001) trend in the relationship between LEA rate and time for hospitalization, ER, and outpatient departments together. The LEA rate for DM patients declined from 372.72/100,000 in 2004 to 61.74/100,000 in 2013. With establishment of an organizing, standardized wound care protocol and integrated multidisciplinary team, we demonstrated a significant decline in the LEA rate both in diabetes foot patients and all patients with diabetes. These improvements can be attributed to introducing an efficient pathway with on-time debridement and early intervention of diabetes foot ulcers. Copyright © 2015 Elsevier Ireland Ltd.

Primum non nocere - The effects of sodium hypochlorite on dentin as used in endodontics.

The medical literature is replete with the maxim 'primum non nocere', cautioning health care providers to avoid doing any harm to human subjects in their delivery of medical care. Sodium hypochlorite (NaOCl) is a well-established irrigant for root canal treatment because of its antimicrobial and organic tissue remnant dissolution capability. However, little is known about the deleterious effect of this strong oxidizing agent on the integrity of human mineralized dentin. Iatrogenically-induced loss of dentin integrity may precipitate post-treatment root fracture and has potential medico-legal complications. In the present work, transmission electron microscopy provided evidence for collagen destruction in the surface/subsurface of dentin treated with high NaOCl concentrations and long contact times. Size exclusion chromatography showed that the hypochlorite anion, because of its small size, penetrated the water compartments of apatite-encapsulated collagen fibrils, degraded the collagen molecules and produced a 25-35µm thick, non-uniform "ghost mineral layer" with enlarged, coalesced dentinal tubules and their lateral branches. Fourier transform-infrared spectroscopy identified increases in apatite/collagen ratio in NaOCl-treated dentin. The apatite-rich, collagen-sparse dentin matrix that remained after NaOCl treatment is more brittle, as shown by the reductions in flexural strength. Understanding the deleterious effects of NaOCl on mineralized dentin enables one to balance the risks and benefits in using high NaOCl concentrations for lengthy periods in root canal debridement. Delineating the mechanism responsible for such a phenomenon enables high molecular weight, polymeric antimicrobial and tissue dissolution irrigants to be designed that abides by the maxim of 'primum non nocere' in contemporary medical practices. The antimicrobial and tissue-dissolution capacities of NaOCl render it a well-accepted agent for root canal debridement. These highly desirable properties, however, appear to be intertwined with the untoward effect of collagen matrix degradation within mineralized dentin. Because of its small size, the hypochlorite anion is capable of infiltrating mineralized collagen and destroying the collagen fibrils, producing a mineral-rich, collagen sparse ghost mineral matrix with reduced flexural strength. Findings from the present work challenge the biosafety of NaOCl when it is used in high concentrations and for lengthy time periods during root canal treatment, and laid the background work for future biomaterials design in debridement of the canal space.

Burn pain is recognized as being maximal during therapeutic procedures, and wound debridement can be more painful than the burn injury itself. Uncontrolled acute burn pain increases the stress response and the incidence of chronic pain and associated depression. Although opiates are excellent analgesics, they do not effectively prevent central sensitization to pain. The anticonvulsant gabapentin has been proven effective for treating neuropathic pain in large placebo-controlled clinical trials. Experimental and clinical studies have demonstrated antihyperalgesic effects in models with central neuronal sensitization. It has been suggested that central neuronal sensitization may play an important role in postoperative pain. The aim of this study was to investigate the effect of gabapentin on morphine consumption and postoperative pain in burn patients undergoing resection of burn wounds. In a randomized, double-blind, placebo-controlled study, 50 burn patients received a single oral dose of gabapentin (1200mg) or placebo 2h before surgery. Anesthesia was induced with propofol and fentanyl and maintained by infusingpropofol, remifentanil, and 50% N2O in O2. All patients received patient-controlled analgesia with morphine at doses of 2.5 mg bolus and a lock-out time of 10 min for 24h before the operation. Pain was assessed on a visual analog scale (VAS) at rest and during movement at 1,4,8,12,16,20, and 24 h before the operation. Heart rate, oxygen saturation, mean arterial blood pressure, respiratory rate, sedation score, and morphine consumption were studied. All the enrolled patients were able to complete the study; therefore, data from 50 patients wereanalyzed. The VAS scores at rest andduring movement at 1,4,8,12,16,20, and 24 h after the operation were significantly lower in the gabapentin group than in the placebo group (P < 0.05). Morphine consumption was significantly lessr in the gabapentin group than in the placebo group (P < 0.05). Sedation scores were similar in the 2 groups at all measured times. There were no differences in adverse effects between the groups. A single oral dose of 1200mg gabapentin resulted in a substantial reduction in postoperative morphine consumption and pain scores after surgical debridement in burn patients.

The purpose of this study was to describe the education, policy, practice, and risk management strategies of nurses performing conservative sharp wound debridement (CSWD) in Canada, prior to the release of the Canadian Association for Enterostomal Therapy Evidence-Based Recommendations for Conservative Sharp Wound Debridement. Data collection was based on a nonrandomized, nonexperimental study design and reported using descriptive statistics. Invitations for health care professionals to participate in a CSWD scan were sent to 4315 people via e-mail through the membership lists of 2 Canadian voluntary professional wound care associations. Skip logic screened out respondents who had no experience in CSWD (n = 57). The total number of professionals who participated was 487. A 26-question electronic scan addressed demographics, education, policy, practice, and risk/quality issues related to CSWD. A comment section was included for some questions. A selected subsample of 397 nurses was chosen from the original total of 487 respondents. Nonnurse respondents were excluded due to the low total number of participants in each of these other professional categories. Nurses perform CSWD in all types of care settings in Canada from outpost nursing stations to hospital wards, homes, and long-term care facilities. The wound education preparation reported varied. The most frequently reported formal wound care education was a 2-day course (59%; n = 220), followed by an enterostomal therapy course (42%; n = 155) and the International Interdisciplinary Wound Care Course (26%; n = 98), with overlapping preparation evident. Eleven percent of respondents (n = 47) reported having taken no formal wound course, and 7% (n = 27) taught themselves to perform CSWD. Twenty-eight percent of nurses (n = 112) were unclear about whether CSWD was within their scope of practice or replied that it was not, and 69% (n = 273) did not know if there was provincial legislation that restricted their practice of CSWD. Forty-eight percent of nurses (n = 181) reported that their institutions do not have policies on CSWD, and 9% (n = 35) did not know. Adverse events associated with CSWD were reported by 196 respondents, with minor bleeding reported most frequently (98% n = 192) by those who answered the question. The education, policy, practice, and risk management of nurses practicing CSWD could benefit from development and dissemination of a set of National Standards and Competencies for this high-risk wound intervention.

Fifty-four juvenile cases under 18 years of age with thoracic and lumbar spinal tuberculosis underwent focus debridement, deformity correction, bone graft fusion, and internal fixation. The treatment effects, complications, and reasons were analyzed retrospectively. There were 54 juvenile cases under 18 years of age with thoracolumbar spinal tuberculosis. The average age was 9.2 years old, and the sample comprised 38 males and 16 females. The disease types included 28 thoracic cases, 17 thoracolumbar cases, and 9 lumbar cases. Nerve function was evaluated with the Frankel classification. Thirty-six cases were performed with focus debridement and deformity correction and were supported with allograft or autograft in mesh and fixed with pedicle screws from a posterior approach. Eight cases underwent a combined anterior and posterior surgical approach. Nine cases underwent osteotomy and deformity correction, and one case received focus debridement. The treatment effects, complications, and bone fusions were tracked for an average of 52 months. According to the Frankel classification, paralysis was improved from 3 cases of B, 8 cases of C, 18 cases of D, and 25 cases of E preoperatively. This improvement was found in 3 cases of C, 6 cases of D, and 45 cases of E at a final follow-up postoperatively. No nerve dysfunction was aggravated. VAS was improved from 7.8 ± 1.7 preoperatively to 3.2 ± 2.1 at final follow-up postoperatively. ODI was improved from 77.5 ± 17.3 preoperatively to 28.4 ± 15.9 at final follow-up postoperatively. Kyphosis Cobb angle improved from 62.2° ± 3.7° preoperatively to 37° ± 2.4° at final follow-up postoperatively. Both of these are significant improvements, and all bone grafts were fused. Complications related to the operation occurred in 31.5% (17/54) of cases. Six cases suffered postoperative aggravated kyphosis deformity, eight cases suffered proximal kyphosis deformity, one case suffered pedicle penetration, one case suffered failure of internal devices, and one case suffered recurrence of tuberculosis. As long as the treatment plan is fully prepared, the surgical option can achieve a satisfactory curative effect in treating juvenile spinal tuberculosis despite some complications.

2018-04-22

This systematic review assesses the efficacy of infrared laser therapy used alone or as an adjunct to nonsurgical or surgical periodontal therapy, on clinical and patient-centered outcomes in patients with periodontitis. Randomized clinical trials (RCTs) with a follow-up duration ≥ 3 months that evaluated root surface debridement (i.e., scaling and root debridement with or without surgical access) to laser therapy alone or laser therapy plus root surface debridement for the treatment of adult patients (≥18 years old) with moderate to severe aggressive or chronic periodontitis were considered eligible for inclusion. The MEDLINE, EMBASE and CENTRAL databases were searched for articles published up to and including March 2016. Random effects meta-analyses were used throughout the review using continuous data (i.e., mean changes from baseline), and pooled estimates were expressed as weighted mean differences (MDs) with their associated 95% confidence intervals (CIs). Additionally, summaries are presented of the included RCTs, critical remarks of the literature and evidence quality rating/strength of recommendation of laser procedures. Of the 475 potentially eligible articles, 28 were included in the review. Individual study outcomes and seven sets of meta-analysis (1 for the nonsurgical treatment of AgP and 9 for nonsurgical and surgical treatment of CP) showed a benefit of laser therapy in improving clinical attachment level (CAL) and probing depth (PD). However, the comparative differences in clinical outcomes were modest (< 1 mm) and the level of certainty for different therapies was considered low-to-moderate (i.e., more information would be necessary to allow for a reliable and definitive estimation of effect/magnitude of therapies on health outcomes). Overall, most of the Strength of Clinical Recommendations of laser therapies were considered weak or based on expert opinion. In patients with moderate to severe periodontitis, the nonsurgical treatment of AgP and CP by SRP plus infrared diode laser, and the surgical treatment of CP by Er:YAG laser therapy alone may promote statistically significant improvements in PD and/or CAL. However, these gains are relatively small (< 1 mm) and provide modest clinical relevance compared to SRP alone. This article is protected by copyright.

1991-12-01

Acute exacerbation of symptoms, or "flare-up," after the debridement of the root canals and provisional restoration is a well-known postoperative complication of endodontic treatment. In this clinical study, various types of intracanal medications were compared for their ability to decrease interappointment flare-ups. The result showed that use of intracanal medicaments containing anti-inflammatory agents in combination with the administration of prophylactic systematic antibiotics was the most effective method of controlling interappointment flare-ups.

2011-07-01

Traditionally, patients with symptomatic sterile pancreatic necrosis or infected necrosis have been managed by open surgical debridement and removal of necrotic tissue. Within the last decade, however, reports of endoscopic pancreatic necrosectomy, an alternative minimally invasive approach, have demonstrated high success rates and low mortality rates. This report describes the indications, technique, and study outcome data of the procedure. While our experience with this technique has recently increased, better selection criteria are needed to identify patients who are most suitable for endoscopic therapy.

Efficient endodontic treatment demands thorough debridement of the root canal system with minimal procedural errors. The inherent weakness of nickel–titanium alloys is their unexpected breakage. Modifications in the design, manufacturing, thermomechanical and surface treatment of alloys and advancements in movement kinetics have shown to improve the fatigue properties of the alloys, reducing the incidence of separation. This review enlightens the impact of these factors on fatigue properties of the alloy. PMID:29674810

Patients might refuse the offer of local anaesthesia (LA) administration prior to dental treatment. This study investigates subjective discomfort perception during non-surgical mechanical periodontal therapy delivered with or without LA. Sixty patients with mild to moderate chronic periodontitis and prior periodontal debridement experience were randomly enrolled in nonsurgical therapy of a quadrant with or without LA administration. Patients were free to comply or not with the allocated LA arrangement. Visual analogue scales (VAS) of discomfort perception at various stages of the treatment as well as overall satisfaction were recorded. Demographic, psychosocial and periodontal parameters were recorded. Thirty-one patients undergoing nonsurgical periodontal therapy not receiving (LA-) and 29 participants receiving LA (LA+) were studied. Compared to LA- patients, LA+ individuals perceived less discomfort during treatment and reported less dental anxiety (p<0.05). Lower overall treatment satisfaction was associated with prior unpleasant periodontal experience (p=0.047). Overall, debridement discomfort was associated with not receiving LA, noncompliance with the pain control regimen allocated, longer treatment duration, greater gingival inflammation and a higher percentage sites with probing pocket depths≥5 mm (p<0.05). Clinicians should be aware that patients who refuse LA can experience higher dental anxiety and therefore may require various pain control strategies for comfort during nonsurgical periodontal therapy, which, if not employed, can lead to less periodontal treatment satisfaction.

The 2 most commonly used topical agents for partial thickness burns are silver sulfadiazine (SSD) and collagenase ointment (CO). Silver sulfadiazine holds antibacterial properties, and eschar separation occurs naturally. Collagenase ointment is an enzyme that cleaves denatured collagen facilitating separation but has no antibacterial properties. Currently, there are no prospective comparative data in children for these 2 agents. Therefore, we conducted a prospective randomized trial. After institutional review board approval, patients were randomized to daily debridement with SSD or CO. Primary outcome was the need for skin grafting. Patients were treated for 2 days with SSD with subsequent randomization. Polymyxin was mixed with CO for antibacterial coverage. Debridements were performed daily for 10 days or until the burn healed. Grafting was performed after 10 days if not healed. From January 2008 to January 2011, 100 patients were enrolled, with no differences in patient characteristics. There were no differences in clinical course, outcome, or need for skin grafting. Wound infections occurred in 7 patients treated with CO and 1 patient treated with SSD (P = .06). Collagenase ointment was more expensive than SSD (P < .001). However, total hospital charges did not differ. There are no differences in outcomes between topical SSD or CO in the management of childhood burns results. Copyright © 2012 Elsevier Inc.

We present data supporting the efficacy of the procedure, laser sulcular debridement (laser curettage), as an important component in the treatment of inflammatory periodontal disease. Laser Assisted New Attachment Procedure (LANAP) is a detailed protocol for the private practice treatment of gum disease that incorporates use of the PerioLase pulsed Nd:YAG Dental Laser for laser curettage. Laser curettage is the removal of diseased or inflamed soft tissue from the periodontal pocket with a surgical dental laser. The clinical trial conducted at The University of Texas HSC at San Antonio, Texas, evaluated laser curettage as an adjunct to scaling and root planing. They measured traditional periodontal clinical indices and used a questionnaire to evaluate patient comfort and acceptance. The Texas data (N=10 patients) are compared with pocket depth changes following LANAP. LANAP data were obtained from a retrospective review of patient records at three private practices (N=65). No significant differences in post treatment probe depth changes were found among the four centers indicating that the procedure produced consistent, favorable outcomes, and that results from controlled scientific clinical trials can be replicated in private practices. Reduction in pocket depths following laser treatment compare well with results obtained with scalpel surgery. The use of the laser offers additional benefits. We also present quantitative evidence from digitized radiographs of increased bone density in affected areas following LANAP.

Stem cells derived from the subcutaneous adipose tissue of debrided burned skin represent an appealing source of adipose-derived stem cells (ASCs) for regenerative medicine. Traditional tissue culture uses fetal bovine serum (FBS), which complicates utilization of ASCs in human medicine. Human platelet lysate (hPL) is one potential xeno-free, alternative supplement for use in ASC culture. In this study, adipogenic and osteogenic differentiation in media supplemented with 10% FBS or 10% hPL was compared in human ASCs derived from abdominoplasty (HAP) or from adipose associated with debrided burned skin (BH). Most (95–99%) cells cultured in FBS were stained positive for CD73, CD90, CD105, and CD142. FBS supplementation was associated with increased triglyceride content and expression of adipogenic genes. Culture in hPL significantly decreased surface staining of CD105 by 31% and 48% and CD142 by 27% and 35% in HAP and BH, respectively (p < 0.05). Culture of BH-ASCs in hPL also increased expression of markers of osteogenesis and increased ALP activity. These data indicate that application of ASCs for wound healing may be influenced by ASC source as well as culture conditions used to expand them. As such, these factors must be taken into consideration before ASCs are used for regenerative purposes. PMID:29138638

Using negative pressure therapy for improving skin graft taking on genital area defects following Fournier gangrene.

PubMed

Orhan, Erkan; Şenen, Dilek

2017-09-01

Fournier's gangrene is an infective necrotizing fasciitis of the perineal, genital and perianal regions. Treatment includes aggressive surgical debridement that often results in extensive loss of genital skin. Skin grafts may be used for reconstruction but skin grafting of the male genitalia is diffucult because the penis and scrotum are mobile and deformable. A variety of methods are used to secure skin graft to recipient beds. We used negative pressure therapy (NPT) to secure skin grafts and improve skin graft taking. We used negative pressure therapy for graft fixation in 13 male patients who underwent debridements with the indication of Fournier gangrene, and whose defects formed were reconstructed with grafts between January 2009, and January 2014. Information about age of the patients, sessions of negative pressure therapy applied before, and after reconstruction, duration of hospital stay, and graft losses during postoperative period were recorded. Median age of the patients was 56.15 (46-72) years. NPT was applied to patients for an average of 6.64 sessions (4-12) before and 1 sessions after graft reconstruction. Patients were hospitalized for an average of 26.7 (20-39) days. Any graft loss was not seen after NPT. Because of the peculiar anatomy of the genital region, anchoring of grafts is difficult so graft losses are often encountered. Use of NPT for ensuring graft fixation on the genital region prevents skin graft shearing.
