    Surgical wounds that become infected are often debrided because clinicians believe that removal of this necrotic or infected tissue will expedite wound healing. There are numerous methods available but no consensus on which one is most effective for surgical wounds. The aim of this review is to determine the effect of different methods of debridement on the rate of debridement and healing of surgical wounds. We developed a search strategy to search the following electronic databases: Wounds Group Specialised Trials Register (searched 3/3/08) , Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2008, issue 1), MEDLINE (1950 to February Week 3 2008 ), EMBASE (1980 to 2008 Week 09) and CINHAL (1982 to February Week 4 2008). We checked the citations within obtained studies to identify additional papers and also relevant conference proceedings. We contacted manufactures of wound debridement agents to ascertain the existence of published, unpublished and ongoing trials. Our search was not limited by language or publication status. We included relevant randomised controlled trials (RCT) with outcomes including at least one of the following: time to complete debridement, or time to complete healing. Two authors independently reviewed the abstracts and titles obtained from the search, two extracted data independently using a standardised extraction sheet, and two independently assessed methodological quality. One author was involved in all stages of the data collection and extraction process, thus ensuring continuity. Five RCTs were eligible for inclusion; all compared treatments for infected surgical wounds and reported time required to achieve a clean wound bed (complete debridement). One trial compared an enzymatic agent (Streptokinase/streptodornase) with saline-soaked dressings and reported the time to complete debridement. Four of the trials compared the effectiveness of dextranomer beads or paste with other products (different comparator

    Surgical wound infection is an important outcome indicator in the postoperative period. A 3-year prospective cohort epidemiological study of 2202 surgical patients from seven surgical wards across two hospitals was carried out using gold standard surveillance methodology. This involved following patients up as inpatients and postdischarge surveillance to 30 days by an independent observer. The results led to the development of a mathematical model for risk of clean, elective surgical wound infection. Risk of surgical wound infection was increased by smoking, higher body mass index, presence of malignancy, haematoma formation, increasing numbers of people in theatre, adherent dressing usage, and higher times to suture removal (P<0.05). The results show that this type of surveillance is an effective way of collecting accurate data on wound infection rates. It was noted that patient care practices affected the surgical wound infection rate and the surveillance was used to facilitate the adoption of evidence-based practice, through recommendations for clean surgery, to reduce the risk from extrinsic risk factors for wound infection. As a result of the implementation of this evidence-based practice there was a significant reduction (P<0.05) in the clean wound infection rate.

    Full Text Available Historical data on closing and suturing of surgical wounds describe a wide range of various suture materials. The choice of the surgical catgut, i.e. the type and diameter, depends on the locality, characteristics and condition of the tissue to be treated. From the standpoint of oral-surgical practice the following clinical parameters are of outstanding importance with respect to the selection of suture material: accumulation of soft deposits on the sutures, score of the adjacent soft tissues and dehiscence of the operative wound. Our prospective clinical study included 150 patients distributed into three groups of 50 subjects. The surgical procedure performed on each patient involved resection (apicotomy of the tooth root end in the intercanine sector of the upper jaw. The following suture materials were applied: Black Silc 5-0, Nylon 5-0 and Vicryl 5-0. The effects of the selected sutures were evaluated according to the wound dehiscence. The effects of the applied sutures were recorded on Days 2, 5 and 7 after the surgery. The comparison of cited parameters of the investigated materials after suturing the oral mucosa revealed that none of the used material was ideal; however, a certain advantage might be given to the synthetic monofilament suture materials.

    Aim of this study is to improve the in vivo knowledge about the real effects and the physiologic repair by a detached stitches silk suture in the 8th zone. The study has been carried out on 44 patients submitted to surgical extraction of the impacted 8th (19 upper and 25 lower) teeth. Clinical and histological controls have demonstrated the usefulness of this suture procedure, since it gives a good histological reaction and in easy and safe. Histological and clinical results have confirmed the usefulness of silk suture, presenting however the inconvenience of stitches removal and bacterial plaque on the surgical wound.

    To compare cefazolin concentrations in biopsied tissue samples collected from surgically created wounds treated with negative pressure wound therapy to those collected from surgically created wounds treated with nonadherent dressings. Prospective, controlled, experimental study. Adult female spayed Beagles (n = 12). Full thickness cutaneous wounds were created on each antebrachium (n = 24). Immediately after surgery, cefazolin (22 mg/kg intravenously [IV]) was administered to each dog and continued every 8 hours during the study. The right wound was randomly assigned to group I or group II whereas the wound on the contralateral antebrachium was assigned to the other group. Group I wounds were treated with negative pressure wound therapy (NPWT) and group II wounds were treated with nonadherent dressings for 3 days. Dressings were changed and tissue biopsies obtained from wound beds at 24 hours intervals for both groups. Cefazolin wound tissue and plasma concentrations were measured by liquid chromatography mass spectrometry (LC-MS/MS). Blood samples for measuring plasma cefazolin concentrations were collected before biopsy sampling. At the time of surgery and at each subsequent bandage change, wound beds were swabbed and submitted for aerobic and anaerobic culture. After initiating cefazolin treatment, wound tissue antibiotic concentrations between treatment groups were not significantly different at any sampling time. Similarly, after initiating cefazolin treatment, plasma cefazolin concentrations were not significantly different at any sampling time for individual dogs. Using a canine experimental model, NPWT treatment of surgically created wounds does not statistically impact cefazolin tissue concentrations when compared with conventional nonadherent bandage therapy. © Copyright 2014 by The American College of Veterinary Surgeons.

    Full Text Available Background/Aim. Using vacuum in medicine has been known from long ago, however, it has not been used for the treatment of wounds. The first experiments in this field were performed by Wagner Fleischmann, University of Ulm, Ulm, West Germany, in 1993. The aim of this study was to present our clinical experience with the treatment of surgical wounds complications in vascular patients by the use of controled vacuum. Method. In a period October 2006 - December 2009 a total of 18 patients with infection and surgical wound dehiscence were treated by the use of vacuum. Vacuum was applied to wounds by placing a polyurethane sponge on them and by fixing a polyurethane foil and a sponge to the surrounding healthy skin so to completely airtight wounds. Over a foil vacuum of - 150 mmHg was applied for a 5-day period, and on the day 6 a foil and a sponge were removed. Results. In all the 18 wounds treated by the use of vacuum secondary wound closing was achieved with no complications and with a significantly shortened time period treatment. Wound infections were healed using this method and only in 2 patients antibiotics were used at the same time. Conclusion. The use of vacuum in the treatment of operative wounds complications is an easy and reliable method contributing significantly to wounds better healing.

    Medicare patients' access to surgical dressings and topical wound care products is greatly influenced by the Medicare payment system that exists in each site of care. Qualified healthcare professionals should consider these payment systems, as well as the medical necessity for surgical dressings and topical wound care products. Scientists and manufacturers should also consider these payment systems, in addition to the Food and Drug Administration requirements for clearance or approval, when they are developing new surgical dressings and topical wound care products. Due to the importance of the Medicare payment systems, this article reviews the Medicare payment systems in acute care hospitals, long-term acute care hospitals, skilled nursing facilities, home health agencies, durable medical equipment suppliers, hospital-based outpatient wound care departments, and qualified healthcare professional offices.

  13. Peripheral surgical wounding and age-dependent neuroinflammation in mice.

    Zhipeng Xu

    Full Text Available Post-operative cognitive dysfunction is associated with morbidity and mortality. However, its neuropathogenesis remains largely to be determined. Neuroinflammation and accumulation of β-amyloid (Aβ have been reported to contribute to cognitive dysfunction in humans and cognitive impairment in animals. Our recent studies have established a pre-clinical model in mice, and have found that the peripheral surgical wounding without the influence of general anesthesia induces an age-dependent Aβ accumulation and cognitive impairment in mice. We therefore set out to assess the effects of peripheral surgical wounding, in the absence of general anesthesia, on neuroinflammation in mice with different ages. Abdominal surgery under local anesthesia was established in 9 and 18 month-old mice. The levels of tumor necrosis factor-α (TNF-α, interleukin-6 (IL-6, Iba1 positive cells (the marker of microglia activation, CD33, and cognitive function in mice were determined. The peripheral surgical wounding increased the levels of TNF-α, IL-6, and Iba1 positive cells in the hippocampus of both 9 and 18 month-old mice, and age potentiated these effects. The peripheral surgical wounding increased the levels of CD33 in the hippocampus of 18, but not 9, month-old mice. Finally, anti-inflammatory drug ibuprofen ameliorated the peripheral surgical wounding-induced cognitive impairment in 18 month-old mice. These data suggested that the peripheral surgical wounding could induce an age-dependent neuroinflammation and elevation of CD33 levels in the hippocampus of mice, which could lead to cognitive impairment in aged mice. Pending further studies, anti-inflammatory therapies may reduce the risk of postoperative cognitive dysfunction in elderly patients.

    A goal of this study is to review perspective technologies of surgical care to the wounded on the basis of an analysis of the experience in medical support in local armed conflicts and a study of the achievements of modern trauma surgery. The study is based on the analysis of personal experience, results of scientific researches being carried out in the Military Medical Academy and a comparison review of available papers and works in the field of our study. Perspective technologies of surgical care to the wounded are strongly dependent on the pre-hospital care: high technologies in personal medical equipment, special disposable devices used in case of life-threatening consequences of injuries and traumas during emergency medical care and advanced trauma management. The main innovation of the last ten years in war surgery is considered to be damage control surgery. Wide application of abbreviated surgical operations (the first phase of damage control surgery) makes the use of remote surgery (telesurgery) for treatment of the wounded more practicable. Increasing effectiveness of military surgeon education is based on the use of all possible achievements in education and information technologies. Feedback in surgical care to the wounded is supplied with analysis of its results in the medical Register of the wounded military.

    Under the laser continuous irradiation one can observe on tissues and organs a whole complex of dystrophic processes including the coagulation necrosis as well as impairements in hemo- and microcirculation. The peculiarity of the inflammatory reaction in the healing process in laser wounds lies in an absence of demarcation leucocytic infiltration and lack of edema on a border of intact tissues and those with thermal necrosis; the healing process is characterised as well as with early proliferative phase. The main role in the reparative process belongs to cells of mononuclear phagocytic system ( macrophages ), wich make the reparative process like an aseptic productive inflammation.

    Sheikh Khalifa Medical City's (SKMC) Surgery Institute was identified as a high outlier in Surgical Site Infections (SSI) based on the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) - Semi-Annual Report (SAR) in January 2012. The aim of this project was to improve SSI rates through accurate wound classification. We identified SSI rate reduction as a performance improvement and safety priority at SKMC, a tertiary referral center. We used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) best practice guidelines as a guide. ACS NSQIP is a clinical registry that provides risk-adjusted clinical outcome reports every six months. The rates of SSI are reported in an observed/expected ratio. The expected ratio is calculated based on the risk factors of the patients which include wound classification. We established a multidisciplinary SSI taskforce. The members of the SSI taskforce included the ACS NSQIP team members, quality, surgeons, nurses, infection control, IT, pharmacy, microbiology, and it was chaired by a colorectal surgeon. The taskforce focused on five areas: pre-op showering and hair removal, skin antisepsis, prophylactic antibiotics, peri-operative maintenance of glycaemia, and normothermia. We planned audits to evaluate our wound classification and our SSI rates based on the SAR. Our expected SSI rates in general surgery and the whole department were 2.52% and 1.70% respectively, while our observed SSI rates were 4.68% and 3.57% respectively, giving us a high outlier status with an odd's ratio of 1.72 and 2.03. Wound classifications were identified as an area of concern. For example, wound classifications were preoperatively selected based on the default wound classification of the booked procedure in the Electronic Medical Record (EMR) which led to under classifying wounds in many occasions. A total of 998 cases were reviewed, our rate of incorrect wound classification

    The wound is a damage of tissue. The process of healing is influenced by many systemic and local factors. The most crucial and the most discussed local factor of wound healing is infection. Surgical site infection in the wound is caused by micro-organisms. This information is known for many years, however the conditions leading to an infection occurrence have not been sufficiently described yet. Correct sampling technique, correct storage, transportation, evaluation, and valid interpretation of these data are very important in clinical practice. There are many methods for microbiological sampling, but the best one has not been yet identified and validated. We aim to discuss the problem with the focus on the imprint technique.

  19. Disposable surgical face masks for preventing surgical wound infection in clean surgery

    Directory of Open Access Journals (Sweden)

    Allyson Lipp

    Full Text Available BACKGROUND: Surgical face masks were originally developed to contain and filter droplets containing microorganisms expelled from the mouth and nasopharynx of healthcare workers during surgery, thereby providing protection for the patient. However, there are several ways in which surgical face masks could potentially contribute to contamination of the surgical wound, e.g. by incorrect wear or by leaking air from the side of the mask due to poor string tension. OBJECTIVES: To determine whether disposable surgical face masks worn by the surgical team during clean surgery prevent postoperative surgical wound infection. SEARCH METHODS: We searched The Cochrane Wounds Group Specialised Register (searched 14 September 2011; The Cochrane Central Register of Controlled Trials (CENTRAL (The Cochrane Library 2011, Issue 3; Ovid MEDLINE (2008 to August Week 5 2011; Ovid MEDLINE (In-Process &Other Non-Indexed Citations September 13, 2011; Ovid EMBASE (2008 to 2011 Week 35; and EBSCO CINAHL (2008 to 9 September 2011. SELECTION CRITERIA: Randomized controlled trials (RCTs and quasi-randomized controlled trials comparing the use of disposable surgical masks with the use of no mask. DATA COLLECTION AND ANALYSIS: Two review authors extracted data independently. MAIN RESULTS: Three trials were included, involving a total of 2113 participants. There was no statistically significant difference in infection rates between the masked and unmasked group in any of the trials. AUTHORS' CONCLUSIONS: From the limited results it is unclear whether the wearing of surgical face masks by members of the surgical team has any impact on surgical wound infection rates for patients undergoing clean surgery.

    significantly (P < 0.05 less scar formation. Conclusion: Among the main concerns that surgeons, physicians, and patients often have is the development infection, oozing, and scar at the incision site following suturing. This always raises the question about which suture to use to avoid the above problems. This study provides evidence that the new technique developed in our lab could be used to compare the wound-lip sealing properties of different surgical suture threads. Using such a technique, the results show that polyurethane is significantly better than other commonly-used suture threads, like polypropylene and polyamide, in relation to wound sealing and scar formation.

  1. Post-Surgical Clinical Monitoring of Soft Tissue Wound Healing in Periodontal and Implant Surgery.

    2017-01-01

    Clinical features of surgical soft tissue wound healing in dentistry have been rarely discussed in the international literature. The aim of the present paper is to highlight both the main clinical findings of surgical wound healing, especially in periodontal and implant dentistry, and the wound healing monitoring procedures which should be followed. Wound inspection after careful food and plaque debridement is the essential part of wound healing monitoring. Periodontal and peri-implant probing should be performed only after tissue healing has been completed and not on a weekly basis in peri-implant tissue monitoring. Telephone follow-up and patient self-assessment scales can also be used the days following surgery to monitor the most common surgical complications such as pain, swelling, bleeding, and bruising. Wound healing monitoring is an important concern in all surgical procedures since it allows to identify signs or/and symptoms possibly related to surgical complications.

    Comparison of postoperative surgical wound infection rates between institutions and over time is only valid if standard, valid and reliable definitions are used. The aim of this review was to assess evidence of validity and reliability of the definition and measurement of surgical wound infection. A systematic review was undertaken of prospective studies of surgical wound infection published over a seven-year period; 1993-1999. The information extracted from individual studies included: definition of surgical wound infection; details of wound assessment scale, scoring or grading scale systems; and evidence of assessment of validity, reliability and feasibility of identified definitions and grading systems. Two independent reviewers appraised 112 prospective studies, 90 of which were eligible for inclusion; eight studies assessed validity and/or reliability. Forty-one different definitions of surgical wound infection were identified, five of which were 'standard' definitions proposed by multi-disciplinary groups. Presence of pus was the most frequently used single component of any definition; the CDC definitions of 1988 and 1992 were the most widely implemented standard definitions; and the ASEPSIS wound assessment scale was the most frequently used quantitative grading tool. Only two formal validations of a definition were found, and six studies of reliability. This review highlights the extent of variation in definition of surgical wound infection used in clinical practice, and the need for validation of both content and organization of a surveillance system. However, realistically, there will have to be a balance between the quality of the measurement and the practicality of surveillance.

    SUMMARY Wound healing is a process driven by biochemical and mechanical variables in which new tissue is synthesised to recover original tissue functionality. Wound morphology plays a crucial role in this process, as the skin behaviour is not uniform along different directions. In this work we simulate the contraction of surgical wounds, which can be characterised as elongated and deep wounds. Due to the regularity of this morphology, we approximate the evolution of the wound through its cross-section, adopting a plane strain hypothesis. This simplification reduces the complexity of the computational problem while maintaining allows for a thorough analysis of the role of wound depth in the healing process, an aspect of medical and computational relevance that has not yet been addressed. To reproduce wound contraction we consider the role of fibroblasts, myofibroblasts, collagen and a generic growth factor. The contraction phenomenon is driven by cell-generated forces. We postulate that these forces are adjusted to the mechanical environment of the tissue where cells are embedded through a mechanosensing and mechanotransduction mechanism. To solve the non-linear problem we use the Finite Element Method and an updated Lagrangian approach to represent the change in the geometry. To elucidate the role of wound depth and width on the contraction pattern and evolution of the involved species, we analyse different wound geometries with the same wound area. We find that deeper wounds contract less and reach a maximum contraction rate earlier than superficial wounds. PMID:24443355

To elucidate the role of wound depth and width on the contraction pattern and evolution of the involved species, we analyse different wound geometries with the same wound area. We find that deeper wounds contract less and reach a maximum contraction rate earlier than superficial wounds. Copyright © 2014 John Wiley & Sons, Ltd.

    Experience of organization of the surgical care in the military hospital to 438 wounded in extremities during armed conflict in Republic of Chechnya is generalized. Maximum reduction of stages of medical evacuation of the wounded in extremities, approaching of the qualified and urgent specialized surgical care directly to the region of battle actions, use of opportunities for it one-moment rendering corresponded to principles of the modern military-medical doctrine. Due to realization of the requirements of the doctrine life of many wounded ++ was saved, terms of treatment, medical and social rehabilitation are reduced. Besides lethality, treatment cost and numbers of transferring to the reserve from the Armed Forces were reduced.

    Reducing Cx43 expression stimulates skin wound healing. This is mimicked in models when Cx43 function is blocked by the connexin mimetic peptide Gap27. IGF-I also stimulates wound healing with IGFBP-5 attenuating its actions. Further, the IGF-I to IGFBP-5 ratio is altered in diabetic skin, where wound closure is impaired. We investigated whether Gap27 remains effective in augmenting scrape-wound closure in human skin wound models simulating diabetes-induced changes, using culture conditions with raised glucose, insulin and IGFBP-5. Gap27 increased scrape-wound closure in normal glucose and insulin (NGI) and to a lesser extent in high glucose and insulin (HGI). IGF-I enhanced scrape-wound closure in keratinocytes whereas IGFBP-5 inhibited this response. Gap27 overcame the inhibitory effects of IGFBP-5 on IGF-I activity. Connexin-mediated communication (CMC) was reduced in HGI, despite raised Cx43, and Gap27 significantly decreased CMC in NGI and HGI. IGF-I and IGFBP-5 did not affect CMC. IGF-I increased keratinocyte proliferation in NGI, and Gap27 increased proliferation in NGI to a greater extent than in HGI. We conclude that IGF-I and Gap27 stimulate scrape-wound closure by independent mechanisms with Gap27 inhibiting Cx43 function. Gap27 can enhance wound closure in diabetic conditions, irrespective of the IGF-I:IGFBP-5 balance. - Highlights: ► Human organotypic and keratinocyte ‘diabetic’ skin models were used to demonstrate the ability of Gap27 to improve scrape-wound closure. ► Gap27 enhanced scrape-wound closure by reducing Cx43-mediated communication, whereas IGFBP-5 retarded cell migration. ► IGF-I and IGFBP-5 did not affect connexin-mediated pathways. ► Gap27 can override altered glucose, insulin, IGF-I, and IGFBP-5 in ‘diabetic’ skin models and thus has therapeutic potential.

    There are several anecdotal clinical articles claiming wound healing and scar superiority using obsidian (volcanic glass) scalpels. In order to determine if skin incisions made with obsidian were superior to those made with standard surgical steel, wound tensile strength, scar width, and histology were assessed in 40 adult male Sprague-Dawley rats. Each rat received two parallel 8-cm dorsal skin incisions, one with an obsidian scalpel and the other with a surgical steel scalpel (no. 15 blade). Data were analyzed by ANOVA. Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days. Scar width, however, was significantly less in the obsidian wounds at 7, 10, and 14 days (p obsidian wounds contained fewer inflammatory cells and less granulation tissue at 7 days.

    Platelets are small anucleate cytoplasmic cell bodies released by megakaryocytes in response to various physiologic triggers. Traditionally thought to be solely involved in the mechanisms of hemostasis, platelets have gained much attention due to their involvement wound healing, immunomodulation, and antiseptic properties. As the field of surgery continues to evolve so does the need for therapies to aid in treating the increasingly complex patients seen. With over 14 million obstetric, musculoskeletal, and urological and gastrointestinal surgeries performed annually, the healing of surgical wounds continues to be of upmost importance to the surgeon and patient. Platelet-rich plasma, or platelet concentrate, has emerged as a possible adjuvant therapy to aid in the healing of surgical wounds and injuries. In this review, we will discuss the wound healing properties of platelet-rich plasma and various surgical applications. Copyright © 2016 Elsevier Inc. All rights reserved.

    There are two triage groups of the walking wounded in a medical company of a brigade/special-purpose medical team: those returning to fighting role and those who have to be evacuated to level 3 echelon of care. The main purposes of surgical care of the walking wounded in the 3rd echelon of care are the following: diagnosis of injury pattern ruling out severe damages and separation of the independent category of the walking wounded. There is medical evacuation of the walking wounded from the 3rd echelon to the 4th echelon deployed in a combat zone. The walking wounded who needs less than 30 days of staying in hospital are evacuated to the garrison military hospitals and medical treatment facilities subordinated to a district military hospital. The wounded with the prolonged period of hospitalization (more than 30 days) are evacuated toward the district military hospital. Treatment of the walking wounded should be accomplished in the military district where the armed conflict goes on.

    Full Text Available Background:The cosmetic result of the surgical scar has long been considered by surgeons as an important factor for patient satisfaction.On the other hand,there has been an old teaching that perfect closure of contaminated wounds increases the rate of infection. We decided to look into this matter and see if this is a fact or a myth. Methods: In this prospective randomized study conducted on 200 patients with suppurative or gangrenous appendicitis,we closed the wounds with a cosmetic subcuticular suture of 4/0 nylon in 100 patients and in the other 100 patients the wound was approximated loosely with a few stitches of 3/0 nylon in vertical mattress fashion during a 14-month period.Results:There was no significant difference in the rate of wound infection between these two groups.Conclusions:This study shows that perfect closure of the wound with subcuticular closure,which gives a very good cosmetic result in comparison with traditional loose closure, does not increase the rate of wound infection.

    Management of lower extremity wounds after Mohs micrographic surgery can pose a challenge to the surgeon. Postoperative reactive edema and inflammation can lead to a painful and protracted healing course. Unna boots deliver zinc oxide to the wound bed and surrounding skin while providing compression and occlusion of the wound. To evaluate the utility of weekly Unna boot therapy in decreasing postoperative edema, inflammation, and morbidity; minimizing postoperative wound care; and improving the rate of wound healing in patients with lower leg surgical defects. Ten patients (6 men, 4 women) aged 72 to 91 with postoperative defects on the distal lower extremity were treated with weekly Unna boots until wounds had sufficiently granulated or re-epithelialized. In all 10 patients, weekly Unna boot therapy was well tolerated, with high satisfaction levels relating to minimal postoperative wound care, rapid granulation, minimal pain, and excellent esthetic outcome of postoperative wounds. No infections or other complications were noted during the healing process. LIMITATIONS This was not a randomized, controlled trial. In patients with postoperative wounds of the lower leg, weekly Unna boots significantly improve the healing process, decrease postoperative pain, and minimize wound care. © 2011 by the American Society for Dermatologic Surgery, Inc.

    Foster, L; Moore, P

    This article, the last in a series of four, discusses the importance of documenting wound care. Studies have shown that nurses do not document wound care as often, or as accurately, as they should in order to comply with the UKCC's (1998) Guidelines for Records and Record Keeping. Although some wound assessment charts have been published and are in use, there is still concern about the validity or reliability of some of these charts. Studies show that further research is necessary in order to validate the charts that are currently in use. An increase in litigation has placed more emphasis on accurate record keeping which shows, in detail, the wound care that is given to each patient. Patients also want to be more informed about their treatment, and this can be done through the use of clinical pathways or multidisciplinary documents. This article also discusses the factors that have to be considered when putting a wound care chart together and gives some examples of existing charts.

    We present a retrospective review of a series of patients from our Service submitted to surgical extra-anatomical grafts. Correlation between diverse variants and ulterior obliteration by thrombosis or infection of the surgical wounds is analyzed. The series included 133 patients surgically treated between 1986 and 1991. The studied variants were: sex, age, type of graft, the material used, length and type of anesthesia, presentation of hypotension during the surgical intervention, diabetes, platelet recount. Fourteen patients (11%) presented early graft obliteration and 15 (11%) presented an infection of their surgical wound. Only the platelet variant showed statistical differences in patients presenting infection. A high recount of platelets could be a factor risk of infection.

    Full Text Available BACKGROUND Surgical site infections are the infections that occur within thirty days after the operative procedure (Except in case of added implants. Surgical site infections are the 3rd most commonly reported nosocomial infections accounting for a quarter of all such infections. A wide range of organisms are known to infect wounds like gram positive cocci, gram negative bacilli, spore formers, aerobes and anaerobes. Despite the advances in operative technique and better understanding of the pathogenesis of wound infections and wound healing, surgical site infections still remain a major source of morbidity and mortality. Hence, this study was done to identify the aetiological bacterial agents and their antibiogram pattern and the risk factors associated with surgical site infections. METHODS Wounds were examined for signs and symptoms of infection in postoperative ward. All the pus swabs were processed and identified as per standard methods of identification. Antibiogram was performed as per CLSI guidelines. The isolates were screened and confirmed with double disc diffusion method using CLSI guidelines. RESULTS The rate of surgical site infections in our study was 8.3%. The rate of surgical site infections was higher (73.3% in emergency surgeries than the elective surgeries. E. coli was the commonest isolate among gram negative bacilli; 33.3% isolates of E. coli were ESBL procedures. E. coli were sensitive to cefepime and ciprofloxacin and showed maximum resistance to ampicillin and ceftazidime. All the E. coli were sensitive to imipenem.

  3. Surgical sutures filled with adipose-derived stem cells promote wound healing.

    Directory of Open Access Journals (Sweden)

    Ann Katharin Reckhenrich

    Full Text Available Delayed wound healing and scar formation are among the most frequent complications after surgical interventions. Although biodegradable surgical sutures present an excellent drug delivery opportunity, their primary function is tissue fixation. Mesenchymal stem cells (MSC act as trophic mediators and are successful in activating biomaterials. Here biodegradable sutures were filled with adipose-derived mesenchymal stem cells (ASC to provide a pro-regenerative environment at the injured site. Results showed that after filling, ASCs attach to the suture material, distribute equally throughout the filaments, and remain viable in the suture. Among a broad panel of cytokines, cell-filled sutures constantly release vascular endothelial growth factor to supernatants. Such conditioned media was evaluated in an in vitro wound healing assay and showed a significant decrease in the open wound area compared to controls. After suturing in an ex vivo wound model, cells remained in the suture and maintained their metabolic activity. Furthermore, cell-filled sutures can be cryopreserved without losing their viability. This study presents an innovative approach to equip surgical sutures with pro-regenerative features and allows the treatment and fixation of wounds in one step, therefore representing a promising tool to promote wound healing after injury.

    Full Text Available Wound complications represent a major source of morbidity in patients undergoing radiation therapy (RT and surgical resection of soft tissue sarcomas (STS. We investigated whether factors related to RT, surgery, patient comorbidities, and tumor histopathology predict the development of wound complications. An observational study of patients who underwent STS resection and RT was performed. The primary outcome was the occurrence of any wound complication up to four months postoperatively. Significant predictors of wound complications were identified using multivariable logistic regression. Sixty-five patients representing 67 cases of STS were identified. Median age was 59 years (range 22–90 and 34 (52% patients were female. The rates of major wound complications and any wound complications were 21% and 33%, respectively. After adjusting for radiation timing, diabetes (OR 9.6; 95% CI 1.4–64.8; P=0.02, grade ≥2 radiation dermatitis (OR 4.8; 95% CI 1.2–19.2; P=0.03, and the use of 3D conformal RT (OR 4.6; 95% CI 1.1–20.0; P=0.04 were associated with an increased risk of any wound complication on multivariable analysis. These data suggest that radiation dermatitis and radiation modality are predictors of wound complications in patients with STS.

    Skin breakdown and infiltration of skin flora are key causative elements in poststernotomy wound infections. We hypothesised that surgical incision management (SIM) using negative pressure wound therapy over closed surgical incisions for 6-7 days would reduce wound infections in a comprehensive poststernotomy patient population. 'All comers' undergoing median sternotomy at our institution were analysed prospectively from 1 September to 15 October 2013 (study group, n = 237) and retrospectively from January 2008 to December 2009 (historical control group, n = 3508). The study group had SIM (Prevena™ Therapy) placed immediately after skin suturing and applied at -125 mmHg for 6-7 days, whereas control group received conventional sterile wound tape dressings. Primary endpoint was wound infection within 30 days. Study group had a significantly lower infection rate than control group: 1·3% (3 patients) versus 3·4% (119 patients), respectively (P incision was primarily closed in 234 of 237 patients (98·7%). SIM over clean, closed incisions for the first 6-7 postoperative days significantly reduced the incidence of wound infection after median sternotomy. Based on these data SIM may be cost-effective in patients undergoing cardiac surgery.

    The authors share their experience gained in rendering early specialized surgical care during combat operations in Donbas, having operated on a total of 139 wounded with lesions of large vessels, of these, 21 (15.1%) presenting with concomitant lesions of vessels. Reconstructive operations were carried out in 122 (87.8%) wounded, ligating operations - in 12 (8.6%), and primary amputations - in 5 (3.6%). Two (1.4%) patients died. Blood flow was restored in 117 (84.2%) patients, with six amputations performed after primary operations. The limb was saved in 116 (83.4%) wounded. Peculiarities of a vascular injury in Donbas comprise a large proportion of severe concomitant vascular wounds and lack of intermediate stages of evacuation. The prognosis of life and limb salvage largely depends on correctly chosen method of temporary arrest of bleeding at first stages of medical evacuation and shortening the terms of rendering first specialized surgical care. The variant of operation (reconstruction, ligation or primary amputation) in severe concomitant vascular wounds should be determined proceeding from the degree of ischaemia and severity of the condition of the wounded person, assessed by means of the Military Surgery - Mangled Extremity Severity Score.

    Advances in preoperative care, surgical techniques and technologies have enabled surgeons to achieve primary closure in a high percentage of surgical procedures. However, often, underlying patient comorbidities in addition to surgical-related factors make the management of surgical wounds primary closure challenging because of the higher risk of developing complications. To date, extensive evidence exists, which demonstrate the benefits of negative pressure dressing in the treatment of open wounds; recently, Incisional Negative Pressure Wound Therapy (INPWT) technology as delivered by Prevena™ (KCI USA, Inc., San Antonio, TX) and Pico (Smith & Nephew Inc, Andover, MA) systems has been the focus of a new investigation on possible prophylactic measures to prevent complications via application immediately after surgery in high-risk, clean, closed surgical incisions. A systematic review was performed to evaluate INPWT's effect on surgical sites healing by primary intention. The primary outcomes of interest are an understanding of INPWT functioning and mechanisms of action, extrapolated from animal and biomedical engineering studies and incidence of complications (infection, dehiscence, seroma, hematoma, skin and fat necrosis, skin and fascial dehiscence or blistering) and other variables influenced by applying INPWT (re-operation and re-hospitalization rates, time to dry wound, cost saving) extrapolated from human studies. A search was conducted for published articles in various databases including PubMed, Google Scholar and Scopus Database from 2006 to March 2014. Supplemental searches were performed using reference lists and conference proceedings. Studies selection was based on predetermined inclusion and exclusion criteria and data extraction regarding study quality, model investigated, epidemiological and clinical characteristics and type of surgery, and the outcomes were applied to all the articles included. 1 biomedical engineering study, 2 animal studies, 15

    The impact of surgical wound infection on public health justifies its surveillance and prevention. Our objectives were to estimate the incidence of surgical wound infection in breast procedures and assess its protocol of antibiotic prophylaxis and preoperative preparation. Observational multicentre prospective cohort study of incidence of surgical wound infection. Incidence was evaluated, stratified by National Nosocomial Infection Surveillance (NNIS) risk index and we calculated the standardized incidence ratio (SIR). The SIR was compared with Spanish rates and U.S. rates. The compliance and performance of the antibiotic prophylaxis and preoperative preparation protocol were assessed and their influence in the incidence of infection with the relative risk. Ten hospitals from the Comunidad de Madrid were included, providing 592 procedures. The cumulative incidence of surgical wound infection was 3.89% (95% CI: 2.3-5.5). The SIR was 1.82 on the Spanish rate and 2.16 on the American. Antibiotic prophylaxis was applied in 97.81% of cases, when indicated. The overall performance of antibiotic prophylaxis was 75%, and 53% for preoperative preparation. No association was found between infection and performance of prophylaxis or preoperative preparation (P>.05). Our incidence is within those seen in the literature although it is somewhat higher than the national surveillance programs. The performance of prophylaxis antibiotic must be improved, as well as the recording of preoperative preparation data. Copyright © 2010 Elsevier España, S.L. All rights reserved.

    The cost of treating diabetes-related disease in New Zealand is increasing and is expected to reach New Zealand dollars (NZD) 1.8 billion in 2021. The financial burden attached to the treatment of diabetic foot wounds is difficult to quantify and reported costs of treatment vary greatly in the literature. As of yet, no study has captured the true total cost of treating a diabetic foot wound. In this study, we investigate the total minimum cost of treating a diabetic foot ulcer at a tertiary institution. A retrospective audit of hospital and interhospital records was performed to identify adult patients with diabetes who were treated operatively for a diabetic foot wound by the department of vascular surgery at Auckland Hospital between January 2009 and June 2014. Costs from the patients' admissions and outpatient clinics from their first meeting to the achievement of a final outcome were tallied to calculate the total cost of healing the wound. The hospital's expenses were calculated using a fully absorbed activity-based costing methodology and correlated with a variety of demographic and clinical factors extracted from patients' electronic records using a general linear mixed model. We identified 225 patients accounting for 265 wound episodes, 700 inpatient admissions, 815 outpatient consultations, 367 surgical procedures, and 248 endovascular procedures. The total minimum cost to the Auckland city hospital was NZD 10,217,115 (NZD 9,886,963 inpatient costs; NZD 330,152 outpatient costs). The median cost per wound episode was NZD 29,537 (NZD 28,491 inpatient costs; NZD 834 outpatient cost). Wound healing was achieved in 70% of wound episodes (average length of healing, 9 months); 19% of wounds had not healed before the patient's death. Of every 3.5 wound episodes, one required a major amputation. Wound treatment modality, particularly surgical management, was the strongest predictor of high resource utilization. Wounds treated with endovascular intervention and no

    Full Text Available Purpose. Surgical site infections (SSIs remain a significant problem after laparotomies. The aim of this review was to assess the evidence on the efficacy of subcutaneous wound drainage in reducing SSI. Methods. MEDLINE database was searched. Studies were identified and screened according to criteria to determine their eligibility for meta-analysis. Meta-analysis was performed using the Mantel-Haenszel method and a fixed effects model. Results. Eleven studies were included with two thousand eight hundred and sixty-four patients. One thousand four hundred and fifty patients were in the control group and one thousand four hundred and fourteen patients were in the drain group. Wound drainage in all patients shows no statistically significant benefit in reducing SSI incidence. Use of drainage in high risk patients, contaminated wound types, and obese patients appears beneficial. Conclusion. Using subcutaneous wound drainage after laparotomy in all patients is unnecessary as it does not reduce SSI risk. Similarly, there seems to be no benefit in using it in clean and clean contaminated wounds. However, there may be benefit in using drains in patients who are at high risk, including patients who are obese and/or have contaminated wound types. A well designed trial is needed which examines these factors.

    Full Text Available Abstract Background The management of brachial plexus injuries due to gunshot wounds is a surgical challenge. Better surgical strategies based on clinical and electrophysiological patterns are needed. The aim of this study is to clarify the factors which may influence the surgical technique and outcome of the brachial plexus lesions caused by gunshot injuries. Methods Two hundred and sixty five patients who had brachial plexus lesions caused by gunshot injuries were included in this study. All of them were male with a mean age of 22 years. Twenty-three patients were improved with conservative treatment while the others underwent surgical treatment. The patients were classified and managed according to the locations, clinical and electrophysiological findings, and coexisting lesions. Results The wounding agent was shrapnel in 106 patients and bullet in 159 patients. Surgical procedures were performed from 6 weeks to 10 months after the injury. The majority of the lesions were repaired within 4 months were improved successfully. Good results were obtained in upper trunk and lateral cord lesions. The outcome was satisfactory if the nerve was intact and only compressed by fibrosis or the nerve was in-contunuity with neuroma or fibrosis. Conclusion Appropriate surgical techniques help the recovery from the lesions, especially in patients with complete functional loss. Intraoperative nerve status and the type of surgery significantly affect the final clinical outcome of the patients.

  14. Bluebelle study (phase A): a mixed-methods feasibility study to inform an RCT of surgical wound dressing strategies

    2016-01-01

    Objectives Dressing primary surgical wounds is common, but the implications for surgical site infection (SSI) remain unknown. The Bluebelle study aimed to determine the feasibility of a randomised controlled trial (RCT) comparing ‘simple’, ‘complex’ or ‘no’ dressings on abdominal wounds, as prespecified in a funder's research brief. Bluebelle includes exploratory work (phase A) to inform a pilot version of the proposed RCT (phase B). Phase A aimed to investigate current dressing practices and perspectives on the proposed RCT, with a view to refining the forthcoming pilot. Design Mixed methods, including semi-structured interviews and document analysis. Setting 6 UK hospitals. Participants 51 patients and 92 clinical professionals from abdominal surgical specialities. Results Professionals had variable interpretations of what constitutes a ‘dressing’, particularly with respect to ‘glue’—a product listed under ‘wound-closure products’ in the British National Formulary, which some surgeons reportedly applied as a ‘wound covering’. Areas of ambiguity arising from interviews informed development of pragmatic definitions, including specification of conditions under which glue constituted a ‘dressing’. Professionals reported that ‘simple’ dressings were routinely used in practice, whereas ‘complex’ dressings were not. This raised questions about the relevance of comparison groups, prompting the design of a survey to determine the types/frequency of dressing use in abdominal surgery (reported elsewhere). This confirmed that complex dressings were rarely used, while ‘glue as a dressing’ was used relatively frequently. ‘Complex dressings’ were therefore substituted for ‘glue as a dressing’ (following an updated Cochrane review, which found insufficient evidence to determine the effectiveness of ‘glue as a dressing’). Patients and professionals acknowledged uncertainty around dressing use and SSI prevention, but felt

    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.

    To analyze the effectiveness of a 0,2% polyhexamethylene biguanide dressing against the infection of a superficial surgical incision site (ISSIS) after a laparoscopic cholecystectomy. A randomized longitudinal single-blind study was conducted with two randomly assigned groups consisting of patients diagnosed with cholelithiasis soon to undergo an elective laparoscopic cholecystectomy. The dependent variable was ISSIS using the criteria of the Centre for Disease Control (CDC) (1999). The independent variables were the use of a 0,2% polyhexamethylene biguanide dressing (Group A), or a non occlusive dressing (Group B). The National Nosocomial Infections Surveillance (NNIS) index was used for assessing the risk of infection. The χ(2) test or Fisher test was used to evaluate the correlation between the independent variables. Of the total 197 cases, 96 (48.7%) were in group A and 101 (51.3%) in group B. No statistical differences were found between genders, duration of surgery (51.4 ± 21.2 vs 52.6 ± 23.4 minutes, in group A and B, respectively), or the NNIS index in either group. Six patients had an ISSIS (3.04%): 1 in group A (1.04%) and 5 in group B (4.95%), P=.212. The study was unable to correlate an ISSIS with the type of surgical dressing that was used, although it was not possible to rule out an association, as the study did not have sufficient statistical power.

    Topical antibiotics are not indicated for postsurgical wound infection prophylaxis in clean and clean-contaminated dermatologic surgeries, yet many dermatologists continue to prescribe them. The objective of our systematic review and meta-analysis was to critically assess the efficacy of topical antibiotics in terms of preventing postsurgical wound infections in the dermatology outpatient setting. PubMed, Embase, MD Consult, Science Direct, Springer Link, DynaMed and Cochrane online medical databases were searched from 1980 to 2013. Using random effects modeling, the pooled odds ratio of developing a postsurgical wound infection was 0.71 (95% CI, 0.42-1.19). Pooled data of the four trials in the meta-analysis did not show a statistically significant difference in incidence of postsurgical wound infections between topical antibiotics and petrolatum/paraffin. In the setting of moist occlusive dressings, there is no statistically significant difference in prophylactic efficacy between applying and not applying ointment to surgical wounds. Wounds at increased risk of developing surgical site infections include wounds in diabetics, wounds located in certain anatomic regions, and wounds created by some surgical procedures. Petrolatum should be used instead of topical antibiotics as a prophylactic measure to prevent postsurgical wound infections in the outpatient dermatologic setting.

    This report describes a case of cortical blindness that followed successful surgical repair of two stab wounds in the heart in a 29-year old Libyan man. The patient presented in a state of pre cardiac arrest (shock and low cardiac output status), following multiple chest stab wounds. Chest tube was immediately inserted. Surgery was urgently performed suturing the two wounds; in the root of the aorta and in the left ventricle, and haemostasis was secured. Cardiac arrest was successfully prevented. The patient recovered smoothly, but 24 hours later he declared total blindness. Ophtalmic and neurological examinations and investigations that included fundoscopy, Electroencephalograms (EEGs) and Computed Tomography Scans revealed no abnormalities, apart from absence of alpha waves in the EEGs. We diagnosed the case as cortical blindness and continued caring for the patient conservatively. Three days later, the patient regained his vision gradually and was discharged on the 7(th) postoperative day without any remarks.

    For a one year period, hair was removed from the operative site with clippers rather than by shaving with a razor or by application of depilatories. The study involved comparison of clean (Class I) wound infection rates in 2,580 patients after clipping was instituted compared with 17,424 patients studied in seven preceding years. There was no significant change in the wound infection rate (1 per cent) when compared with the three years immediately preceding. There was no change in the identified distribution of the infecting organism. Failure to show a clear reduction in wound infection rate was probably related to the low historic base line rate. There were definite benefits achieved by avoiding cancellation of elective operations, by using operating room personnel more efficiently and by expediating the surgical schedule.

    Bariatric surgery is a successful method for weight loss in cases of morbid obesity; however, as an invasive procedure, surgical complications may occur. Low-level laser therapy (LLLT) has been increasingly used due to its effectiveness in controlling the inflammatory response, accelerating tissue repair, and reducing pain. The objective of this study was to investigate photobiomodulation effects after bariatric surgery and determine the laser actions during the inflammatory process, wound healing (clinical observation), and analgesia. This study was a randomized, placebo-controlled, clinical trial in which 85 patients underwent Roux en-Y gastric bypass (RYGB) by conventional techniques (i.e., open surgery). Patients were divided into two groups and were irradiated with LLLT at 10 different points through the surgical scar in three sessions of applications: the laser group (laser-on) consisted of 43 patients who received the CW diode laser (MMOptics), while the placebo group (laser-off) consisted of 42 patients who were treated by the same protocol but with a disabled laser. Temperature was measured by a digital thermometer in both groups, and pain was evaluated using the visual analogue scale for pain. Biochemical analysis and digital images were used to document and evaluate the inflammatory response as well as tissue repair process at the surgical wound site. Patients in the laser group demonstrated diminished wound temperature as erythrocyte sedimentation rate (ESR) compared with the placebo group, indicating better inflammatory process control as well as improved wound healing and reduced pain. LLLT applied with the described protocol led to a decrease by biochemical markers and wound temperature compared with the placebo, which indicated that LLLT was able to control the inflammatory process; in addition, seroma and pain were reduced and cicatrization was improved by this preventive procedure.

    OBJECTIVES Deep sternal wound infections are significant and severe complications following cardiac surgery and substantially influence perioperative morbidity and mortality. We present the experience of our department using two different surgical treatments over a three-year period. METHODS Between January 2009 and December 2011, a total of 3274 cardiac procedures with complete median sternotomy were performed in our department. In 94 patients (3%), a deep sternal wound infection occurred, including sternal instability with consecutive surgical treatment. The patients either received wound debridement with sternum refixation and suction-irrigation drainage (SID; n = 72) or sternum refixation only (RF; n = 22) if there was sternal instability with limited signs of infection. SID was routinely installed for 7 days: the irrigation solution contained neomycin. In all cases, swabs were taken and analysed. The different methods were evaluated in respect of their clinical outcomes. RESULTS The success rate—defined as single, uncomplicated procedure—of the SID treatment was 74%, compared with 59% of the isolated sternum refixation. Complications included continuous infection, recurrence of sternal instability and wound necrosis. Eighty-eight percent of the swabs in the SID group were positive, compared with 32% in the sternal refixation only group. The dominating pathogenic germs were coagulase-negative staphylococci and staphylococcus aureus. Mortality was 10% for the SID group and 5% for the RF group. CONCLUSIONS Contrary to accepted opinion, the suction-irrigation drainage is an appropriate therapy for deep sternal wound infections. Nevertheless, deep sternal wound infections after cardiac surgery remain severe complications and are related to increased morbidity and mortality. PMID:23529753

    2014-01-01

    The purpose of this review article was to understand and analyze the scientific production related to the occurrence of perioperative hypothermia and the incidence of infection on the surgical site. For this purpose, a search was conducted in the databases LILACS, MEDLINE, PubMed, CINAHL and Cochrane, using the health science descriptors DECS, from 2004 to 2009. A total of 91 articles were found. After eliminating duplicate items and using selection criteria for inclusion, six manuscripts remained for analysis. The studies were classified as retrospective, prospective, case studies, and clinical trials. After analysis, the majority of studies showed that hypothermia must be prevented during the perioperative period to reduce complications in the healing process of the surgical incision. Therefore, unadverted hypothermia directly influences in surgical site healing, increasing the incidence of infection in the surgical wound.

    Antibiotic prophylaxis is the most suitable tool for preventing surgical wound infection. This study evaluated adequacy of antibiotic prophylaxis in surgery for knee arthroplasty and its effect on surgical site infection. Prospective cohort study. We assessed the degree of adequacy of antibiotic prophylaxis, the causes of non-adequacy, and the effect of non-adequacy on surgical site infection. Incidence of surgical site infection was studied after a maximum incubation period of a year. To assess the effect of prophylaxis non-adequacy on surgical site infection we used the relative risk adjusted with the aid of a logistic regression model. The study covered a total of 1749 patients. Antibiotic prophylaxis was indicated in all patients and administered in 99.8% of cases, with an overall protocol adequacy of 77.6%. The principal cause of non-compliance was the duration of prescription of the antibiotics (46.5%). Cumulative incidence of surgical site infection was 1.43%. No relationship was found between prophylaxis adequacy and surgical infection (RR=1.15; 95% CI: .31-2.99) (P>.05). Surveillance and infection control programs enable risk factors of infection and improvement measures to be assessed. Monitoring infection rates enables us to reduce their incidence. Adequacy of antibiotic prophylaxis was high but could be improved. We did not find a relationship between prophylaxis adequacy and surgical site infection rate. Copyright © 2017 SECOT.

    Surgical wound irrigation has long been debated as a potentially critical intraoperative measure taken to prevent the development of surgical site infection (SSI). Unlike many other SSI prevention efforts, there are no official practice guidelines or recommendations from any major medical group for the practice of surgical irrigation. As a result, practitioner implementation of the 3 major irrigation variables (delivery method, volume, and solution additives) can differ significantly. A focus group of key thought leaders in infection prevention and epidemiology convened recently to address the implications of different surgical irrigation practices. They identified an urgent need for well-designed clinical trials investigating surgical irrigation practices, improved collaboration between surgical personnel and infection preventionists, and examination of existing evidence to standardize irrigation practices. The group agreed that current published data are sufficient to support the elimination of antibiotic solutions for surgical irrigation; the avoidance of surfactants for surgical irrigation; and the use of sterile normal saline, sterile water, and 1 medical device containing a sterile 0.05% chlorhexidine gluconate solution followed by sterile saline. Given the current lack of sufficient evidence identifying ideal delivery method and volume choices, expert opinion must be relied on to guide best practice.

    ABSTRACT Objective: to estimate the healing rate of complex surgical wounds and its associated factors. Method: retrospective cohort study from 2003 to 2014 with 160 outpatients of a Brazilian university hospital. Data were obtained through consultation of the medical records. Survival function was estimated using the Kaplan-Meier method and Cox regression model to estimate the likelihood of the occurrence of healing. Results: the complex surgical wound healing rate was 67.8% (95% CI: 60.8-74.9). Factors associated with a higher likelihood of wound healing were segmentectomy/quadrantectomy surgery, consumption of more than 20 grams/day of alcohol, wound extent of less that 17.3 cm2 and the length of existence of the wound prior to outpatient treatment of less than 15 days, while the use of hydrocolloid covering and Marlex mesh were associated with a lower likelihood of healing. Conclusion: the wound healing rate was considered high and was associated with the type of surgical intervention, alcohol consumption, type of covering, extent and length of wound existence. Preventive measures can be implemented during the monitoring of the evolution of the complex surgical wound closure, with possibilities of intervention in the modifiable risk factors. PMID:27737379

    Acute Achilles tendon ruptures is one of the commonest tendon injury of the foot and ankle. The management of this problem is still controversial. Treatment can be classified into non-surgical and surgical types. Surgical management can be subdivided into open repair, percutaneous with or without adjunct of arthroscopy. In compare with non-surgical management, surgical management will decrease the tendon re-rupture rate. However, the possible surgical complications including wound breakdown and sural nerve injury are still quite significant. Percutaneous repair technique has the advantage of less chance of wound breakdown, but the rate of tendon re-rupture is higher than that after open tendon repair, because the repair is usually weaker than that achieved in open repair. Lui have described an endoscopic assisted repair with the Krackow locking suture. However, the technique is complicated and six portal wounds are needed. A simpler way of applying the Krackow suture through the portal wound has been described for reattachment of Achilles tendon insertion after endoscopic calcaneoplasty. We describe a mini-open approach of Achilles tendon repair with the Krackow locking suture. By means of release of the medial edge of the investing fascia, the Achilles tendon can be mobilized easily and the Krackow locking suture can be applied through a 1.5cm medial wound. Hopefully, this can improve the strength of repair and maintaining the advantage of minimally invasive tendon repair.

    Previous studies have shown that surgical castration wounds take between 10 and 61 d to heal. The objectives of this work were to describe healing, inflammation, lying behavior, and serum concentration of substance P after surgical castration in beef calves and to evaluate the effect of a possible intervention, a single injection of flunixin meglumine (1.1 mg/kg IV, a NSAID), on the healing process. Calves (mean±SE: 25±2.0 d of age; 54±1.4 kg BW) were surgically castrated with or without an injection of flunixin immediately before the procedure (n=24/treatment). Healing was measured with a 5-point scale (1=fresh wound, 5=no visible incision or inflammation) as well as weight gain, scrotal size, and scrotal surface temperature, on d 1, 2, 3, 7, 14, 21, 28, 35, 49, and 63 after castration. Serum concentration of substance P was recorded on all d, including d 0, but not d 63. Lying behavior was recorded with loggers from 2 d before to 29 d after castration. Inflammation, as measured by scrotal size, peaked on d 2 and 3 after the procedure (e.g., 51±1.0 mm on d 2 versus 28±1.3 mm before castration) and then declined with time (Pflunixin had more lying bouts than those that received saline (flunixin by time interaction; P=0.052), but this pattern emerged on and after d 8, well after the 3 to 8 h half-life of this NSAID. In conclusion, castration caused inflammation in the days that followed, and the wounds required a minimum of 4 wk to heal. Provision of an NSAID had no effect on these outcomes.

    Cyanoacrylate has been used in several fields of different surgical specialties as an adhesive for closure of gingival flaps and in mucous and cutaneous lacerations. One of its advantages is that it has an excellent immunological response. In view of aesthetic needs, cyanoacrylate has been applied with satisfactory results, when compared with sutures. It presents better coaptation of edges of cutaneous and mucosal lesions, smaller residual scars, and biocompatibility. However, it is limited to areas of little tissue tension. This work attempts to provide a literature review with the aim of revealing the advantages of using tissue adhesives, especially cyanoacrylates, in wound coaptation in comparison with conventional methods.

    This study developed an animal model of surgically wounded submandibular glands (SMGs) and investigated the effects of collagen gel with basic fibroblast growth factor (bFGF) on tissue regeneration of surgically wounded SMGs in vivo. The animal model was produced by creating a surgical wound using a 3-mm diameter biopsy punch in SMGs. The wound was filled with collagen gel with bFGF (bFGF group) or without bFGF (control group). In the animal model of surgically wounded SMGs, salivary glands without scar tissue around the wound area were observed with smaller areas of collagen gel. Small round and spindle-shape cells invaded the collagen gel in both groups after operation day (AOD) 5, and this invasion dramatically increased at AOD 7. Host tissue completely replaced the collagen gel at AOD 21. The invading immune cells in the group treated with collagen gel with bFGF were positive for vimentin, a-smooth muscle actin (aSMA), CD49f, c-kit and AQP5 at AOD 7. Similarly, the mRNA expression of vimentin, aSMA, CD49f, keratin19 and AQP5 was also increased. This study suggests that the use of collagen gels with bFGF improves salivary gland regeneration.

    Flow within a model surgical opening during insufflation with heated carbon dioxide was studied using computational fluid dynamics. A volume of fluid method was used to simulate the mixture of ambient air and carbon dioxide gas. The negative buoyancy of the carbon dioxide caused it to fill the wound and form a protective layer on the internal surfaces for a range of flow rates, temperatures, and angles of patient inclination. It was observed that the flow remained attached to the surface of the model due to the action of the Coanda effect. A flow rate of 10 L/min was sufficient to maintain a warm carbon dioxide barrier for a moderately sized surgical incision for all likely angles of inclination.

    The biological activities and therapeutic potential of phytochemical-decorated Au nanoparticles (Phyto-AuNPs) were investigated through the treatment of Phyto-AuNPs on the dorsal skin of rats via transdermal drug delivery process in order to regenerate surgical wounded and burned skin. Two different Phyto-AuNPs were applied to the dorsal skin: gallic acid-isoflavone--covered AuNPs (GI-AuNPs) and protocatechuic acid-isoflavone--covered AuNPs (PI-AuNPs). From the biological activity monitoring, it has been resulted that 5-fold thicker epidermis (ER), 50% reduction of metalloproteinase-1 (MMP-1) level, 3-fold higher superoxide dismutase (SOD) activity were obtained in the Phyto-AuNP-treated group, compared with a vehicle group (deionized water (DI-water) treatment). Moreover, the Phyto-AuNPs treatment on the surgical and burn damaged Sprague-Dawley (SD) rats induced higher expression of vascular endothelial growth factor (VEGF) and angiopoietin-2 (Ang-2). It would be plausible that antioxidant property of Phyto-AuNPs assist the acceleration and activation of biomolecules in the healing mechanism, where Phyto-AuNPs can be potential candidates for skin regeneration and wound healing.

    Full Text Available Sindhu Priya Dhas, Suruthi Anbarasan, Amitava Mukherjee, Natarajan Chandrasekaran Center for Nanobiotechnology, VIT University, Vellore, India Abstract: Bombyx mori silk fibers are an important biomaterial and are used in surgical sutures due to their remarkable biocompatibility. The major drawback to the application of biomaterials is the risk of bacterial invasion, leading to clinical complications. We have developed an easy and cost-effective method for fabrication of antibacterial silk fibers loaded with silver nanoparticles (AgNPs by an in situ and ex situ process using an aqueous extract of Rhizophora apiculata leaf. Scanning electron microscopy revealed that well dispersed nanoparticles impregnated the silk fibers both in situ and ex situ. The crystalline nature of the AgNPs in the silk fibers was demonstrated by X-ray diffraction. The thermal and mechanical properties of the silk fibers were enhanced after they were impregnated with AgNPs. The silver-coated silk fibers fabricated by the in situ and ex situ method exhibited more than 90% inhibition against Pseudomonas aeruginosa and Staphylococcus aureus. Silk fibers doped with AgNPs were found to be biocompatible with 3T3 fibroblasts. The results obtained represent an important advance towards the clinical application of biocompatible AgNP-loaded silk fibers for prevention of surgical wound infections.

    Full Text Available Background and Aims: Modified Radical Mastectomy (MRM is the commonly used surgical procedure for operable breast cancer, which involves extensive tissue dissection. Therefore, wound instillation with local anaesthetic may provide better postoperative analgesia than infiltration along the line of incision. We hypothesised that instillation of bupivacaine through chest and axillary drains into the wound may provide postoperative analgesia. Methods: In this prospective randomised controlled study 60 patients aged 45-60 years were divided into three groups. All patients were administered general anaesthesia. At the end of the surgical procedure, axillary and chest wall drains were placed before closure. Group C was the control with no instillation; Group S received 40 ml normal saline, 20 ml through each drain; and Group B received 40 ml of 0.25% bupivacaine and the drains were clamped for 10 min. After extubation, pain score for both static and dynamic pain was evaluated using visual analog scale and then 4 th hourly till 24 h. Rescue analgesia was injection tramadol, if the pain score exceeds 4. Statistical analysis was performed using SPSS version 13. Results : There was a significant difference in the cumulative analgesic requirement and the number of analgesic demands between the groups (P: 0.000. The mean duration of analgesia in the bupivacaine group was 14.6 h, 10.3 in the saline group and 4.3 h in the control group. Conclusion : Wound instillation with local anaesthetics is a simple and effective means of providing good analgesia without any major side-effects.

    Full Text Available In this single case study, we attempt to outline the possible effect of low-level laser therapy (LLLT on delayed wound healing and pain in chronic dehiscent sternotomy of a diabetic individual. The methods that were employed to evaluate changes pre and post irradiation were wound photography, wound area measurement, pressure ulcer scale of healing (PUSH, and visual analogue scale (VAS for pain. After irradiation, proliferation of healthy granulation tissue was observed with decrease in scores of PUSH for sternal dehiscence and VAS for bilateral shoulders and sternal dehiscence. We found that LLLT irradiation could be a novel method of treatment for chronic sternal dehiscence following coronary artery bypass grafting, as it augments wound healing with an early closure of the wound deficit. Hence, this might be translated into an early functional rehabilitation and decreased pain perception of an individual following surgical complication.

    Full Text Available Abstract Background Wound infections are a common complication of surgery that add significantly to the morbidity of patients and costs of treatment. The global trend towards reducing length of hospital stay post-surgery and the increase in day case surgery means that surgical site infections (SSI will increasingly occur after hospital discharge. Surveillance of SSIs is important because rates of SSI are viewed as a measure of hospital performance, however accurate detection of SSIs post-hospital discharge is not straightforward. Methods We conducted a systematic review of methods of post discharge surveillance for surgical wound infection and undertook a national audit of methods of post-discharge surveillance for surgical site infection currently used within United Kingdom NHS Trusts. Results Seven reports of six comparative studies which examined the validity of post-discharge surveillance methods were located; these involved different comparisons and some had methodological limitations, making it difficult to identify an optimal method. Several studies evaluated automated screening of electronic records and found this to be a useful strategy for the identification of SSIs that occurred post discharge. The audit identified a wide range of relevant post-discharge surveillance programmes in England, Scotland and Wales and Northern Ireland; however, these programmes used varying approaches for which there is little supporting evidence of validity and/or reliability. Conclusion In order to establish robust methods of surveillance for those surgical site infections that occur post discharge, there is a need to develop a method of case ascertainment that is valid and reliable post discharge. Existing research has not identified a valid and reliable method. A standardised definition of wound infection (e.g. that of the Centres for Disease Control should be used as a basis for developing a feasible, valid and reliable approach to defining post

    Resin is a natural product of coniferous trees. Salves manufactured from spruce resin (Picea abies) have been used for centuries to treat wounds and skin infections. We report a pilot clinical trial designed to investigate healing rates, factors that contribute to delayed wound healing, cost-effectiveness, and incidence of allergic reactions when resin salve is used to treat complicated surgical wounds. The trial involved 23 patients in whom wound healing after surgery was delayed. These patients were assigned to resin salve treatment. The primary outcome measure was the number of days to complete wound healing. Secondary objectives included an assessment of factors contributing to delayed wound healing, an estimation of associated costs, and an investigation into the occurrence of allergic reactions related to resin salve therapy. The study achieved a healing rate of 100%. The mean ± SD healing time was 43 ± 24 days. The mean ± SD wound size (length × width × depth) was (29 ± 19) × (12 ± 7) × (4 ± 3) mm. Wound size, use of corticosteroids or other immunosuppressants, and immobilization were statistically significant (P < 0.05) contributors to delayed wound healing and impaired re-epithelialization. The total mean ± SD costs of the resin salve treatment were €45.0 ± 26.0 per patient during the entire treatment period and €1.2 ± 0.5 per treatment day. The rate of allergic reactions was 0%. The results of this pilot trial indicate that complicated surgical wounds may be treated successfully with resin salve. The treatment method is clinically effective and cost-effective, and the rate of allergic reactions is low. © 2012 The International Society of Dermatology.

    Full Text Available Several studies have shown that wound infection (surgical site infection [ ssi ] rates fall when surgeons are provided with data on their performance. Since 1987, the authors have been performing concurrent surveillance of surgical patients and confidentially reporting surgeon-specific ssi rates to individual surgeons and their clinical directors, and providing surgeons with the mean rates of their peers. The program has been gradually refined and expanded. Data are now collected on wound infection risk and report risk adjusted rates compared with the mean for hospitals in the United States National Nosocomial Infections Surveillance (nnis data bank. Since inception through to December 1993, ssi rates have fallen 68% in clean contaminated general surgery cases (relative risk [rr] 0.36, 95% ci 0.2 to 0.6, P=0.0001, 64% in clean plastic surgery cases (rr 0.35, 95% ci 0.06 to 1.8, 72% in caesarean section cases (rr 0.23, 95% ci 0.03 to 1.96 and 42% in clean cardiovascular surgery cases (rr 0.59, 95% ci 0.34 to 1.0. In clean orthopedic surgery the ssi rate remained stable from 1987 through 1992. In 1993 a marked increase was experienced. Reasons for this are being explored. Overall there was a 32% decrease in ssi rate between the index year and 1993 or, in percentage terms, 2.8% to 1.9% (rr 0.65, 95% ci 0.51 to 0.86, P=0.002. ssi surveillance should become standard in Canadian hospitals interested in improving the quality of surgical care and reducing the clinical impact and cost associated with nosocomial infection.

    This study was a randomized-controlled trial comparing the standard type of dry dressing, Mepore, with moist wound healing, using a hydrofiber dressing, Aquacel, in primary closed wounds after vascular surgery. The endpoints were patient comfort, cost-effectiveness, infections, wound complications....... No difference in the infection rate (13% vs. 11%, p=0.73), length of hospital stay, or wound complications was noted between the two groups. We conclude that although the Aquacel dressing needed significantly fewer changes than the conventional dressing, this did not influence the patient comfort. Moreover...

    The Indicadores Clínicos de Mejora Continua de la Calidad (INCLIMECC) program was established in Spain in 1997. INCLIMECC is a prospective system of health care-associated infection (HAI) surveillance that collects incidence data in surgical and intensive care unit patients. The protocol is based on the National Healthcare Safety Network (NHSN) surveillance system, formerly known as the National Nosocomial Infection Surveillance (NNIS) system, and uses standard infection definitions from the US Centers for Disease Control and Prevention. Each hospital takes part voluntarily and selects the units and surgical procedures to be surveyed. This report is a summary of the data collected between January 1997 and June 2012. A total of 370,015 patients were included, and the overall incidence of surgical wound infection (SWI) was 4.51%. SWI rates are provided by NHSN operating procedure category and NNIS risk index category. More than 27% of the patients received inadequate antibiotic prophylaxis, the main reason being unsuitable duration (57.05% of cases). Today, the INCLIMECC network includes 64 Spanish hospitals. We believe that an HAI surveillance system with trained personnel external to the surveyed unit is a key component not only in infection control and prevention, but also in a quality improvement system.

    In this article we explore the experience of suffering from a surgical site infection, a common complication of surgery affecting around 5 per cent of surgical patients, via an interview study of 17 patients in the Midlands in the UK. Despite their prevalence, the experience of surgical site infections has received little attention so far. In spite of the impairment resulting from these iatrogenic problems, participants expressed considerable stoicism and we interpret this via the notion of emotional capital. This idea derives from the work of Pierre Bourdieu, Helga Nowotny and Diane Reay and helps us conceptualise the emotional resources accumulated and expended in managing illness and in gaining the most from healthcare services. Participants were frequently at pains not to blame healthcare personnel or hospitals, often discounting the infection's severity, and attributing it to chance, to ‘germs’ or to their own failure to buy and apply wound care products. The participants' stoicism was thus partly afforded by their refusal to blame healthcare institutions or personnel. Where anger was described, this was either defused or expressed on behalf of another person. Emotional capital is associated with deflecting the possibility of complaint and sustaining a deferential and grateful position in relation to the healthcare system. PMID:25470322

    Objective:To ascertain the antimicrobial susceptibility profile of Pseudomonas aeruginosa (P. aeruginosa) recovered from surgical site infections (SSIs). Methods:The study was retrospective in nature and was compiled for a period of five years (1st February, 2004-31st January, 2009). Data were generated from the culture of post-operative wound swab specimens by the microbiology laboratory of University of Calabar Teaching Hospital. Relevant information from the patients’ records was compiled, such as age, gender, type of surgical procedure, microorganisms recovered and their antibiotic sensitivity patterns. Obtained data was analysed by using Epi Info 6 statistical software. Results:Of the 4 533 wound swab specimens processed, 673 were culture positive and P. aeruginosa was recovered from 13.1%of the culture positive specimens with its rate of recovery decreasing with age progression (P0.05). Most of the P. aeruginosa isolates were from general surgery wards and least from orthopaedic wards. Ofloxacin, ceftriaxone and augmentin were the most active antibiotics while ampicillin, tetracycline and co-trimoxazole were the least active antibiotics, with no antibiotic having a 100%activity against the organism. Conclusions:In view of the high resistance displayed by P. aeruginosa recovered from SSIs, adequate antiseptic procedures should be entrenched to avoid colonization of surgical wounds by this microorganism as well as others with similar sensitivity profile. Ofloxacin, ceftriaxone and augmentin may be considered for prevention of P.aeruginosa infection.

    Bombyx mori silk fibers are an important biomaterial and are used in surgical sutures due to their remarkable biocompatibility. The major drawback to the application of biomaterials is the risk of bacterial invasion, leading to clinical complications. We have developed an easy and cost-effective method for fabrication of antibacterial silk fibers loaded with silver nanoparticles (AgNPs) by an in situ and ex situ process using an aqueous extract of Rhizophora apiculata leaf. Scanning electron microscopy revealed that well dispersed nanoparticles impregnated the silk fibers both in situ and ex situ. The crystalline nature of the AgNPs in the silk fibers was demonstrated by X-ray diffraction. The thermal and mechanical properties of the silk fibers were enhanced after they were impregnated with AgNPs. The silver-coated silk fibers fabricated by the in situ and ex situ method exhibited more than 90% inhibition against Pseudomonas aeruginosa and Staphylococcus aureus. Silk fibers doped with AgNPs were found to be biocompatible with 3T3 fibroblasts. The results obtained represent an important advance towards the clinical application of biocompatible AgNP-loaded silk fibers for prevention of surgical wound infections.

    Full Text Available The escalating physiological, psychological, social and financial burdens of wounds and wound care on patients, families and society demand the immediate attention of the health care sector. Many forces are affecting the changes in health care provision for patients with chronic wounds, including managed care, the limited number of wound care therapists, an increasingly ageing and disabled population, regulatory and malpractice issues, and compromised care. The physician is also faced with a number of difficult issues when caring for chronic wound patients because their conditions are time consuming and high risk, represent an unprofitable part of care practice and raise issues of liability. Telemedicine enhances communication with the surgical wound care specialist. Digital image for skin lesions is a safe, accurate and cost-effective referral pathway. The two basic modes of telemedicine applications, store and forward (asynchronous transfer and real-time transmission (synchronous transfer, e.g. video conference, are utilized in the wound care setting. Telemedicine technology in the hands of an experienced physician can streamline management of a problem wound. Although there is always an element of anxiety related to technical change, the evolution of wound care telemedicine technology has demonstrated a predictable maturation process.

    The primary aim of this study was to determine the effect of positive bacterial cultures at the time of closure on dehiscence rates. Pre and post-débridement wound cultures from patients undergoing serial surgical débridement of infected wounds were compared with outcomes 30 days postoperatively. One-hundred patients were enrolled; 35 were excluded for incomplete culture data. Sixty-five patients were evaluated for species counts, including Coagulase negative Staphylococcus, and semi-quantitative culture data for each débridement. The post-débridement cultures on the date of closure had no growth in 42 patients (64.6%) of which 6 dehisced (14.3%), and 36 remained closed; with no statistically significant difference in dehiscence rates (p=0.0664). Pre-débridement cultures from the 1(st) débridement of the 65 patients showed 8 patients had no growth, 29 grew 1 species, 19 grew 2 species, and 9 had 3-5 species. There was a reduction in the number of species and improvement of semi-quantitative cultures with each subsequent débridement. The dehiscence rate for those who had 2 débridements (n=42) was 21.4% at 30 day follow-up and 21.7% in those who had 3 débridements (n=23). The number of débridements had no statistical significance on dehiscence rates. The presence of Coagulase negative Staphylococcus (CoNS) on the day of closure was a statistically significant risk for dehiscence within 30 days (p=0.0091) postoperatively. This data demonstrates: (1) positive post-débridement cultures (scant/rare, growth in enrichment broth) at the time of closure did not affect overall dehiscence rates (p=0.0664), (2) the number of species and semi-quantitiative culture results both improved with each subsequent débridement, (3) the number of surgical débridement did not influence post-closure dehiscence rates. (4) Positive cultures containing Coagulase negative Staphylococcus at the time of closure is a risk factor for dehiscence (p=0.0091). This article is protected by

    Surgical site infection is one of the most common complications following Lower Segment Cesarean Section, which accounts for prolonged hospital stay thereby increasing expense. Prophylactic antibiotics in cesarean section reduces surgical site infection significantly. The best protection is provided when tissue level of antibiotics are adequate before incision, without prejudice to neonatal infectious morbidity. The objective of this study was to compare the incidence of surgical site wound infection with prophylactic antibiotics given before skin incision and after cord clamping following delivery of baby. This was a prospective, hospital based study, in which hundred cases of cesarean deliveries who received antibiotics prophylaxis one hour before the skin incision were compared with another 100 cases where antibiotic was given after cord clamping following delivery of the baby. Surgical site infection occurred in 3% of women who received antibiotics prophylaxis before skin incision as compared to 6% in whom antibiotic was given after cord clamping. It was statistically not significant (p = 0.465).

    Postsurgical wound care has a great impact on patients' prognosis. It often takes few days, even few weeks, for the wound to stabilize, which incurs a great cost of health care and nursing resources. To assess the wound condition and diagnosis, it is important to segment out the wound region for further analysis. However, the scenario of this strategy often consists of complicated background and noise. In this study, we propose a wound segmentation algorithm based on Canny edge detector and genetic algorithm with an unsupervised evaluation function. The results were evaluated by the 112 clinical images, and 94.3% of images were correctly segmented. The judgment was based on the evaluation of experimented medical doctors. This capability to extract complete wound regions, makes it possible to conduct further image analysis such as intelligent recovery evaluation and automatic infection requirements.

    Obese women undergoing caesarean section (CS) are at increased risk of surgical site infection (SSI). Negative Pressure Wound Therapy (NPWT) is growing in use as a prophylactic approach to prevent wound complications such as SSI, yet there is little evidence of its benefits. This pilot randomized controlled trial (RCT) assessed the effect of NPWT on SSI and other wound complications in obese women undergoing elective caesarean sections (CS) and also the feasibility of conducting a definitive trial. Ninety-two obese women undergoing elective CS were randomized in theatre via a central web based system using a parallel 1:1 process to two groups i.e., 46 women received the intervention (NPWT PICO™ dressing) and 46 women received standard care (Comfeel Plus(®) dressing). All women received the intended dressing following wound closure. The relative risk of SSI in the intervention group was 0.81 (95% CI 0.38-1.68); for the number of complications excluding SSI it was 0.98 (95% CI 0.34-2.79). A sample size of 784 (392 per group) would be required to find a statistically significant difference in SSI between the two groups with 90% power. These results demonstrate that a larger definitive trial is feasible and that careful planning and site selection is critical to the success of the overall study.

    Full Text Available Lectins are a structurally heterogeneous group of highly specific carbohydrate-binding proteins. Due to their great biotechnological potential, lectins are widely used in biomedical research. The purpose of the present study was to evaluate the healing potential of the lectin of Bauhinia variegata (nBVL and its recombinant isoform (rBVL-1. Following surgical creation of dorsal skin wounds, seven groups of mice were submitted to topical treatment for 12 days with lectin, D-galactose, BSA and saline. The animals were anesthetized and euthanized on POD 2, 7 and 12 in order to evaluate the healing potential of each treatment. The parameters considered included wound size, contraction rate, epithelialization rate and histopathological findings. Wound closure was fastest in animals treated with rBVL-1 (POD 7. nBVL was more effective than the controls. All skin layers were reconstructed and keratin deposition increased. Our findings indicate that the lectin of Bauhinia variegata possesses pro-healing properties and may be employed in the treatment of acute skin wounds.

    2011-03-01

    Full Text Available Abstract Background Odontogenic necrotizing fasciitis of the neck is a fulminant infection of odontogenic origin that quickly spreads along the fascial planes and results in necrosis of the affected tissues. It is usually polymicrobial, occurs frequently in immunocompromised patients, and has a high mortality rate. Case presentation A 69-year old Mexican male had a pain in the maxillar right-canine region and a swelling of the submental and submandibular regions. Our examination revealed local pain, tachycardia, hyperthermia (39°C, and the swelling of bilateral submental and submandibular regions, which also were erythematous, hyperthermic, crepitant, and with a positive Godet sign. Mobility and third-degree caries were seen in the right mandibular canine. Bacteriological cultures isolated streptococcus pyogenes and staphylococcus aureus. The histopathological diagnosis was odontogenic necrotizing fasciitis of the submental and submandibular regions. The initial treatment was surgical debridement and the administration of antibiotics. After cultures were negative, the surgical wound was treated with a growth factor-enriched autologous plasma eight times every third day until complete healing occurred. Conclusions The treatment with a growth factor-enriched autologous plasma caused a rapid healing of an extensive surgical wound in a patient with odontogenic necrotizing fasciitis. The benefits were rapid tissue regeneration, an aesthetic and a functional scar, and the avoidance of further surgery and possible complications.

    Weapon injuries in armed conflict are likely to receive medical attention. Other types of injuries, like traffic accidents, continue to occur during armed conflict. Injuries caused by weapons and by traffic accidents require treatment, but reports and figures to help in prioritizing care are scarce. In a prospective observational study, all emergency patients admitted to the surgical ward in a public hospital of the Central African Republic were evaluated for the cause of their main injury. The proportion of patients injured by weapons and by traffic accidents was analyzed with respect to the level of violence. Seventy-eight patients were included in this study. Weapon injuries accounted for 50 (64%) admissions and traffic accidents for 28 (36%). These proportions varied significantly according to the weekly level of violence (χ(2)=46.8; Ptraffic accidents are an important, but overlooked, drain on surgical resources in low-income countries with armed conflict. Their proportion in relation to weapon wounded fluctuates with the level of violence. Humanitarian medical organizations might prepare themselves not only for weapon injuries, but also for wounds caused by traffic accidents.

    Prevention of surgical site infections and the reduction of wound-related complication rates have become increasingly emphasized by hospital task groups and government agencies given the degree of economic burden it places on the health care system. Platelet-rich plasma (PRP) contains growth factors and other biomolecules that promote endogenous microbicidal activity. We hypothesized that PRP would help prevent postoperative infection and delayed wound healing (DWH). We randomized patients having foot or ankle surgery to the treatment group receiving intraoperative PRP (applied to operative field) and platelet-poor plasma at closing (PPP, on the sutured skin) or the control group (no PRP/PPP). The incidence of deep surgical site infection and DWH (collectively called endpoints) was compared between groups (n = 250/group). PRP had a mean 5.3-fold platelet concentration compared to whole blood, with concentrated white blood cells. Mean age (±SD) of patients was 52 years (±15), 65% were women. Minor and major operative procedures were included. Patients were followed for 60 days. Seventy controls had PRP prepared for assay of growth factors. Procedure mix, ASA scores, mean operative times, and comorbidity mix were similar between groups. The primary result was no difference in number of endpoints between groups: 19 patients in the PRP group (7.6%) versus 18 controls (7.2%). Endpoints were deep surgical site infections in 2 PRP/PPP patients and 1 control, and DWH in 17 PRP/PPP patients and 17 controls. Analysis of PRP samples revealed a large variation in growth factor concentrations between patients. Intraoperative application of PRP/PPP did not reduce the incidence of postoperative infection or DWH. Growth factor profiles varied greatly between patients, suggesting that the potentially therapeutic treatment delivered was not consistent from patient-to-patient.

    According to the literature, incisional closure complications may range from postoperative surgical site infections, representing 17-22% of health care-associated infections, surgical wound dehiscence and formation of haematomas or seromas, and can lead to delayed or impaired incision healing. These kinds of situations are more common when wounds are closed under tension or in specific patient morbidities. Obesity, in particular, is associated with an impaired blood flow to tissues, predisposing the patient to increased risk of wound complications by various mechanisms. Incisional complications can become relevant economic burdens for health care systems because of an increase in the average length of hospital stay and readmissions, and additional medical and surgical procedures. Thus, a preventive therapy may have a critical role in the management of healing. Negative pressure wound therapy (NPWT) technology as delivered by Prevena™ Customizable™ (Kinetic Concepts Inc., San Antonio, TX) has recently been the focus of a new investigation, as a prophylactic measure to prevent complications via immediate postoperative application in high-risk, clean, closed surgical incisions. The authors present a 62-year-old class II obese female, who underwent bilateral inguinal dermolipectomy. Prophylactic NPWT as delivered by Prevena™ was performed successfully over surgical incisions. Cosmetic and therapeutic results are shown.

    to estimate the healing rate of complex surgical wounds and its associated factors. retrospective cohort study from 2003 to 2014 with 160 outpatients of a Brazilian university hospital. Data were obtained through consultation of the medical records. Survival function was estimated using the Kaplan-Meier method and Cox regression model to estimate the likelihood of the occurrence of healing. the complex surgical wound healing rate was 67.8% (95% CI: 60.8-74.9). Factors associated with a higher likelihood of wound healing were segmentectomy/quadrantectomy surgery, consumption of more than 20 grams/day of alcohol, wound extent of less that 17.3 cm2 and the length of existence of the wound prior to outpatient treatment of less than 15 days, while the use of hydrocolloid covering and Marlex mesh were associated with a lower likelihood of healing. the wound healing rate was considered high and was associated with the type of surgical intervention, alcohol consumption, type of covering, extent and length of wound existence. Preventive measures can be implemented during the monitoring of the evolution of the complex surgical wound closure, with possibilities of intervention in the modifiable risk factors. estimar a taxa de cicatrização de ferida cirúrgica complexa e seus fatores associados. coorte retrospectiva de 2003 a 2014 com 160 pacientes ambulatoriais de um hospital universitário brasileiro.

    The objective of the present study is to assess the safety and feasibility of the use of telemedicine-based services for surgical wound care and to measure patient satisfaction with telemedicine-based follow-up. 24 patients were included, they were provided with a corporate mail address. On day 7 after surgery patients sent, via email, an image of their surgical wound together with a completed questionnaire in order to obtain an early diagnosis. Two independent physicians studied this information and the histologic analysis of the specimen. On day 8, all patients underwent face-to-face office examination by a third physician and all of them completed a satisfaction questionnaire at the end of the study. The use of telemedicine-based services showed a sensitivity of 100%, a specificity of 91.6%, a positive predictive value of 75% and a negative predictive value of 100%. Degree of concordance between the two physicians, as regards the necessity of face-to-face follow-up yielded a kappa coefficient of 0.42 (standard error 0.25 and confidence interval 95% (0.92-0.08), which means a moderate agreement between the two evaluations. 94% of patients were satisfied with telemedicine-based follow-up and 93% showed their preference for this procedure over conventional methods. The telemedicine-based follow-up, has proven to be feasible and safe for the evaluation of early postoperative complications. Patients reported high levels of satisfaction with the procedure. Telemedicine-based follow-up could become standard practice with the development of a specific mobile application.

    Phyllocaulis boraceiensis mucus has been studied as a potential source of new natural compounds that are capable of inducing proliferation and remodeling tissue. The aim of this study was to evaluate the clinical aspects of healing in the wounded mouse skin, which was treated with an ointment that was composed of mucus, which was released by P boraceiensis. Mice were submitted to a 1-cm dorsal excision. The control group (T1) was treated with papain; the T2 group was treated with papain that was associated with 0.18 μg/μL of mucus; and the T3 group was treated with papain that was associated with 0.012 μg/μL of mucus. Accelerated proliferation was observed after 3 days in the T3 group, presenting a high deposition of fibroblasts at the wound margin, whereas accelerated proliferation in the T1 group began 5 days after surgery. The T2 group presented inflammation during all periods of observation, and even when healing had already begun, the new tissue showed capillary fragility. Remodeling began after 4 days in the T3 group, whereas remodeling began after 6 days in the other groups. T3 showed edema, hyperemia, and bleeding only until the fifth day, and granulation and scar tissues intensely appeared from the 11th day forward. T1 and T2 groups exhibited edema, hyperemia, and bleeding until the 11th day, and granulation and scar tissues appeared after the 13th day. The healing process and wound closure were efficient after the daily application of 0.012 μg/μL P boraceiensis mucus.

    Multispectral imaging (MSI) is an optical technique that measures specific wavelengths of light reflected from wound site tissue to determine the severity of burn wounds. A rapid MSI device to measure burn depth and guide debridement will improve clinical decision making and diagnoses. We used a porcine burn model to study partial thickness burns of varying severity. We made eight 4 × 4 cm burns on the dorsum of one minipig. Four burns were studied intact, and four burns underwent serial tangential excision. We imaged the burn sites with 400-1000 nm wavelengths. Histology confirmed that we achieved various partial thickness burns. Analysis of spectral images show that MSI detects significant variations in the spectral profiles of healthy tissue, superficial partial thickness burns, and deep partial thickness burns. The absorbance spectra of 515, 542, 629, and 669 nm were the most accurate in distinguishing superficial from deep partial thickness burns, while the absorbance spectra of 972 nm was the most accurate in guiding the debridement process. The ability to distinguish between partial thickness burns of varying severity to assess whether a patient requires surgery could be improved with an MSI device in a clinical setting.

    To investigate the prevalence and the risk factors of surgical-site infection (SSI) and delayed wound healing (DWH) in patients with rheumatoid arthritis (RA) underwent orthopedic surgery. We reviewed the records of 1036 elective orthopedic procedures undertaken in RA patients. Risk factors for SSI and DWH were assessed by logistic regression analysis using age, body mass index, disease duration, pre-operative laboratory data, surgical procedure, corticosteroid use, co-morbidity, and use of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and biological DMARDs (bDMARDs) as variables. SSI and DWH were identified in 19 cases and 15 cases, respectively. One case of SSI and three cases of DWH were recorded among 196 procedures in patients using bDMARDs. Foot and ankle surgery was associated with an increased risk of SSI (odds ratio (OR), 3.167; 95% confidence interval (CI), 1.256-7.986; p = 0.015). Total knee arthroplasty (TKA; OR, 4.044; 95% CI, 1.436-11.389; p = 0.008) and disease duration (OR, 1.004; 95% CI, 1.000-1.007; p = 0.029) were associated with an increased risk of DWH. Our results indicated foot and ankle surgery, and TKA and disease duration as risk factors for SSI and DWH, respectively. bDMARDs was not associated with an increased risk of SSI and DWH.

    Salt, vinegar and wine sounds more like a recipe from the Saturday kitchen, but in 1667 it was all a surgeon could use to close wounds, along with silk and linen strips. In providing this service, barbers and surgeons found themselves confused and intertwined, struggling for professional recognition that was about to experience reform. Allegations of neglect in the aftermath of a major seafaring battle on the very shores of our capital city required the court of King Charles II to search for a solution of supreme magnitude to accommodate the hundreds of maimed sailors who were littering the streets of London. A campaign to conceal the horrors of warfare began which lead to the implementation of the Greenwich charter and the construction of a hospital which the architect Christopher Wren helped to design.

    The objective of this study was to trace the source and route of transmission of methicillin-resistant Staphylococcus epidermidis (MRSE) in the surgical wound during cardio-thoracic surgery, and to investigate the possibility of reducing wound contamination by wearing special scrub suits. In total 65 elective operations for coronary artery bypass grafting (CABG) with or without concomitant valve replacement were investigated. All staff present in the operating room wore conventional scrub suits during 33 operations and special scrub suits during 32 operations. Samples were taken from the hands of the scrubbed team after surgical scrub but before putting on sterile gowns and gloves, and from patients' skin (incisional area of sternum and vein harvesting area of legs) after preoperative skin preparation with chlorhexidine gluconate. Air samples were taken during operations. Samples were also taken from the wound just before closure. Total counts of bacteria on sternal skin and from the wound (cfu/cm2) were calculated as well as total counts of bacteria in the air (cfu/m3). Strains of MRSE recovered from the different sampling sites were compared by pulsed field gel electrophoresis (PFGE). It was found that wearing special scrub suits did not reduce the number of air-samples where MRSE was found compared with conventional scrub suits. The risk factor most strongly associated with MRSE in the wound at the end of the operation was preoperative carriage of MRSE on sternal skin; RR 2.42 [95% CI 1.43-4.10], P= 0.021. By use of PFGE, it was possible to identify the probable source for four MRSE isolates recovered from the wound. In three cases the source was the patients own skin. Finding MRSE in air-samples, or on the hands of the scrubbed team, were not risk factors for the recovery of MRSE in the wound at the end of operation. In conclusion, with a total bacterial air count around 20 cfu/m3 and a low proportion of MRSE, the reduction of total air counts by use of tightly

    In early breast cancer, local relapses represent a determinant and not simply an indicator of risk for distant relapse and death. Notably, 90% of local recurrences occur at or close to the same quadrant of the primary cancer. Relevance of PI3K/mTOR/p70S6K signaling in breast tumorigenesis is very well documented. However, the pathway/s involved in the process of breast cancer local relapse are not well understood. The ribosomal protein p70S6K has been implicated in breast cancer cell response to post-surgical inflammation, supporting the hypothesis that it may be crucial also for breast cancer recurrence. Here, we show that p70S6K activity is required for the survival of breast cancer cells challenged in "hostile" microenvironments. We found that impairment of p70S6K activity in breast cancer cells strongly decreased their tumor take rate in nude mice. In line with this observation, if cells were challenged to grow in anchorage independence or in clonogenic assay, growth of colonies was strongly dependent on an intact p70S6K signaling. This in vitro finding was particularly evident when breast cancer cells were grown in the presence of wound fluids harvested following surgery from breast cancer patients, suggesting that the stimuli present in the post-surgical setting at least partially relied on activity of p70S6K to stimulate breast cancer relapse. From a mechanistic point of view, our results indicated that p70S6K signaling was able to activate Gli1 and up-regulate the anti-apoptotic protein Bcl2, thereby activating a survival response in breast cancer cells challenged in hostile settings. Our work highlights a previously poorly recognized function of p70S6K in preserving breast cancer cell survival, which could eventually be responsible for local relapse and opens the way to the design of new and more specific therapies aiming to restrain the deleterious effects of wound response.

The EDT wound, however became infected requiring serial debridements of soft tissue, rib cartilage and sternum. Regional flap options such as pectoralis major and latissimus dorsi muscle flaps could not be employed due to inadequate reach of these flaps. Additionally, bilateral transection of the internal mammary arteries during emergency thoracotomy eliminated the use of rectus abdominis muscles as pedicled flaps based on the superior epigastric vasculature. Therefore, the EDT wound was reconstructed by using the right rectus abdominis muscle as a free flap. The deep inferior epigastric vessels of the flap were anastomosed to the right internal mammary vessels proximal to their transection level in the third-forth intercostal space. The flap healed with no further wound complications.

    The wound healing process after surgery alters the area surrounding the original tumor and around the scar, and the modified microenvironment is more favorable for tumor recurrence. Intraoperative radiotherapy (IORT) is one of the more novel strategies in breast cancer (BC) treatment. Irradiation during surgery has effects on the tumor microenvironment, abrogating the proliferative cascade induced by surgical wound healing. The aim of the present study was to determine the effect of surgical wound fluids from IOERT treatment (RT-WF) compared with wound fluids from conservative-breast surgery only (WF) on the cancer stem cell phenotype in a panel of BC cell lines. Post-operative wound fluids were derived from patients with BC who underwent a tumor resection (quadrantectomy) plus intraoperative electron radiotherapy using a single dose of ≤10 Gy on the tumor bed and surrounding tissues, or from those who underwent a tumor resection without IOERT. Cell lines were incubated with 10% wound fluids, and after 4 days, the cluster of differentiation (CD)44+/CD24−/low phenotype and aldehyde dehydrogenase 1 (ALDH1) activity were determined by flow cytometry. The two types of fluid each affected the CD44+/CD24−/low phenotype. The results varied markedly between each cell line, even for the same histological subtypes. RT-WF decreased the CD44+/CD24−/low populations in the basal-like BT-549 and MDA-MB-468 cell lines, whereas in the luminal type MCF7 cell line, the two fluids inhibited these populations. The HER-OE subtypes harbored a minimal CD44+/CD24−/low population, but the growth of SK-BR-3 was stimulated by the two post-operative fluids. WF exhibited a stronger effect on ALDH1 activity compared with RT-WF. The stimulatory effect was dependent on the histological subtype of the cell line and the strongest dependence was observed in luminal subtypes characterized by low dehydrogenase activity in the control group.

    Full Text Available Abstract Background Postoperative surgical site infections cause substantial morbidity, prolonged hospitalization, costs and even mortality and remain one of the most frequent surgical complications. Approximately 14% to 30% of all patients undergoing elective open abdominal surgery are affected and methods to reduce surgical site infection rates warrant further investigation and evaluation in randomized controlled trials. Methods/design To investigate whether the application of a circular plastic wound protector reduces the rate of surgical site infections in general and visceral surgical patients that undergo midline or transverse laparotomy by 50%. BaFO is a randomized, controlled, patient-blinded and observer-blinded multicenter clinical trial with two parallel surgical groups. The primary outcome measure will be the rate of surgical site infections within 45 days postoperative assessed according to the definition of the Center for Disease Control. Statistical analysis of the primary endpoint will be based on the intention-to-treat population. The global level of significance is set at 5% (2 sided and sample size (n = 258 per group is determined to assure a power of 80% with a planned interim analysis for the primary endpoint after the inclusion of 340 patients. Discussion The BaFO trial will explore if the rate of surgical site infections can be reduced by a single, simple, inexpensive intervention in patients undergoing open elective abdominal surgery. Its pragmatic design guarantees high external validity and clinical relevance. Trial registration http://www.clinicaltrials.gov NCT01181206.

    This review article intends to discuss the clinical management of wounds in respect to a pathophysiological background. Recent results of research in the field of wound healing are demonstrated. Wound healing can be seen as aseptic inflammatory response to a traumatic stimulus. The activation of the clotting cascade by the trauma induces a sequence of humoral and cellular reactions. Platelets, granulocytes and macrophages are activated stepwisely. In the first phase of wound healing the wounded tissue area will be prepared for phagocytosis by enzymatic degradation of ground substance and depolymerisation of protein macromolecules (wound edema). Following the phagocytic microdebridement mesenchymal cells proliferate and produce matrix substance. Microcirculation within the traumatized area will be restored by angiogenesis, macroscopically observed as new formed granulation tissue. This leads to the wound healing phase of scar tissue formation. In this complexity of reactions naturally many possibilities of impairment are given. The most common complication during wound healing is the infection. It can be seen as self reinforcing process. The therapy of the impairment of wound healing consists in the disruption of the specific vicious circle, in the case of an osseus infection that would be a macrodebridement (that is necrectomy) and biomechanical stabilization. The surgical management of wounds principally consists in ensuring an undisturbed sequence of the healing process. This can be done by the wound excision that supports the phagocytic microdebridement. A further possibility is to avoid overwhelming formation of edema by eliminating the traumatic stimulus, by immobilization of the injured region and by ensuring a physiological microenvironment with a primary suture if possible. There are up to the present no drugs available to enhance cell proliferation and to regulate wound healing but it seems that experimental research is successful in characterizing

    The World Health Organization's surgical safety checklist is designed to improve adherence to operating room safety standards, and its use has been shown to reduce complications among surgical patients. The objective of our study was to assess the impact of the implementation of the checklist on safety-related issues in the operating room and on postoperative adverse events in neurosurgery. From structured questionnaires delivered to operating room personnel, answers were analyzed to evaluate communication and safety-related issues during 89 and 73 neurosurgical operations before and after the checklist implementation, respectively. From the analyzed operations, 83 and 67 patients, respectively, were included in a retrospective analysis of electronic patient records to compare the length of hospital stay, reported adverse events, and readmissions. In addition, the consistency of operating room documentation and patient records was assessed. Communication between the surgeon and the anesthesiologist was enhanced, and safety-related issues were better covered when the checklist was used. Unplanned readmissions fell from 25% to 10% after the checklist implementation (p = 0.02). Wound complications decreased from 19% to 8% (p = 0.04). The consistency of documentation of the diagnosis and the procedure improved. The use of the checklist improved safety-related performance and, contemporarily, reduced numbers of wound complications, and readmissions were observed.

    Postsurgery dressing changes in diabetic foot amputation wounds and surgical wounds healing by secondary intention are often conducted in the operating room under general anesthesia. A prospective comparative cohort study was performed in 60 patients (n = 60: n = 30/n = 30) with secondary-intention surgical wounds (82% had forefoot and/or digit[s] amputations) to compare 2 different dressing types. Patients at the study center gave informed written consent, after which they were randomly allocated to one of the treatment groups. Group A received a biocellulose dressing with polyhexanide, and group B a hydrophobic dressing with dialkyl-carbamoyl-chloride. In both groups, gauze was used as secondary dressing and fixed with a film dressing. One day after surgery, the dressings were removed by the surgeon and patient-reported pain and dressing adherence/integrity were evaluated. The number of patients that required general anesthesia was determined during the procedure and afterward. All patients (n = 60; n = 30/n = 30) were included in the intention-to-treat analysis. Pain levels in group A were significantly (t (59) = 4.026, P < .000) lower upon dressing removal, when compared with group B; in group A, n = 21 reported no pain versus n = 8 (26%) for group B. In group A, the dressing adhered in 7 subjects (23%) versus n = 27 (90%) of cases in group B (P = .000). No anesthesia was required for the patients in group A, contrary to group B, where 16% of patients received general anesthesia for dressing removal. Pain levels were significantly lower and the dressing adhered significantly less in group A, compared with group B, demonstrating a better quality of life for the patients in group A.

    Systemic antibiotic therapy in post-operative wound care remain controversial leading to escalation in levels of multi-resistant bacteria with unwanted morbidity and mortality. Recently zinc (Zn) because of multiple biophysiological functions, gain considerable interest for wound care. Based on our current understanding, the present study was designed with an intent to produce improve therapeutic approaches for post-operative wound management using composite multi-functional antibiotic carrier. The study involved the fabrication, characterization and pre-clinical evaluation of cefazolin nanofiber mats loaded with zinc oxide (ZnO) and comparing co-formulated mats with individual component, enable a side by side comparison of the benefits of our intervention. Minimum inhibitory concentration (MIC) of the drug, ZnO nanoparticles (ZnONPs) and drug-ZnONP mixture against Staphylococcus aureus was determined using micro dilution assay. The fabricated nanofibers were then evaluated for in-vitro antimicrobial activity and the mechanism of inhibition was predicted by scanning electron microscopy (SEM). Further these nanofiber mats were evaluated in-vivo for wound healing efficacy in Wistar rats. Study revealed that the average diameter of the nanofibers is around 200–900 nm with high entrapment efficiency and display sustained drug release behavior. The combination of ZnO and cefazolin in 1:1 weight ratio showed higher anti-bacterial activity of 1.9 ± 0.2 μg/ml. Transmission electron microscopy of bacterial cells taken from the zone of inhibition revealed the phenomenon of cell lysis in tested combination related to cell wall disruption. Further composite medicated nanofiber mats showed an accelerated wound healing as compared to plain cefazolin and ZnONP loaded mats. Macroscopical and histological evaluations demonstrated that ZnONP hybrid cefazolin nanofiber showed enhanced cell adhesion, epithelial migration, leading to faster and more efficient collagen synthesis

    Postoperative spinal wound dehiscence is a significant complication following the posterior midline approach. It is postulated that this approach disrupts the vasculature supplying the paraspinal muscles and overlying skin. Although the spinal vasculature has been investigated previously, the smaller arterioles have not been described in the context of the posterior midline approach. Eight cadaveric neck and posterior torso specimens were dissected after injection with a radio-opaque lead oxide mixture and subsequent radiographs taken were analyzed. The deep cervical, vertebral, superficial cervical, and occipital arteries consistently supplied the cervical paraspinal muscles. The latter two arteries also vascularized the overlying skin. The deep cervical arteries were found to be located lateral to the C3 to C6 vertebrae, vulnerable to damage with the posterior approach. In the thoracic region, the superior and posterior intercostal arteries consistently supplied the spinal muscles. In all specimens, two small anastomotic vessels posterior to the laminae were found connecting the intercostal artery perforators. Both the arterial perforators and their anastomotic channels were situated in the surgical field and susceptible to damage with the posterior approach. It is likely that the disruption in spinal vasculature contributes to the multifactorial problem of wound dehiscence with the posterior midline approach. Copyright © 2012 Wiley Periodicals, Inc.

    Full Text Available Vitiligo is an acquired skin disorder characterized by the destruction of melanocytes resulting in achromic macules and patches involving the affected skin. Multiple methods of treatments have emerged to manage vitiligo, including medical and surgical techniques. Among the surgical techniques described in the management of vitiligo are minipunch grafting, split-thickness skin grafting, hair follicle transplantation, suction blister grafting, and cultured and non-cultured autologous melanocyte transplantation. However, prior to grafting optimal recipient-site preparation is needed for graft survival and successful repigmentation outcomes. Similarly, post-operative care of the recipient site is vital to yielding a viable graft irrespective of the transplantation technique employed. This article reviews the multiple methods employed to prepare the recipient site in vitiligo surgeries and the post-surgical conditions which optimize graft viability. A pubmed search was conducted utilizing the key words listed below.

    Full Text Available Introduction. The missiles of modern firearms can cause severe fractures of the extremity. High velocity missile fractures of the tibia are characterized by massive tissue destruction and primary contamination with polymorphic bacteria. Treatment of these fractures is often complicated by delayed healing, poor position healing, nonhealing and bone tissue infection. Case Outline. We present the management of tibial nonunion after wounding by high velocity missile and primary treatment by external fixation in a 25-year-old patient. The patient was primarily treated with external fixation and reconstructive operations of the soft tissue without union of the fracture. Seven months after injury we placed a compression-distraction external fixator type Mitkovic and started with compression and distraction in the fracture focus after osteotomy of the fibula and autospongioplasty. We recorded satisfactory fracture healing and good functional outcome. Conclusion. Contamination and devitalization of the softtissue envelope increase the risk of infection and nonunion in fractures after wounding by high velocity missile. The use of the compression-distraction external fixator type Mitkovic may be an effective method in nonunions of the tibia after this kind of injury.

    To report our experience with computed tomography (CT) scans to detect traumatic arthrotomies of the knee (TAK) joint based on the presence of intra-articular air. Retrospective review. Level I trauma center. Sixty-two consecutive patients (63 knees) underwent a CT scan of the knee in the emergency department and had a minimum of 14 days follow-up. Cohort of 37 patients (37 knees) from the original 62 patients who underwent a saline load test (SLT). CT scan and SLT. Positive traumatic arthrotomy of the knee (+TAK) was defined as operating room (OR) confirmation of an arthrotomy or no intra-articular air on CT scan (-iaCT) (and -SLT if performed) with follow-up revealing a septic knee. Periarticular wound equivalent to no traumatic arthrotomy (pw = (-TAK)) was defined as OR evaluation revealing no arthrotomy or -iaCT (and -SLT if performed) with follow-up revealing no septic knee. All 32 knees with intra-articular air on CT scan (+iaCT) had OR confirmation of a TAK and none of these patients had a knee infection at a mean follow-up of 140.0 ± 279.6 days. None of the 31 patients with -iaCT had a knee infection at a mean follow-up of 291.0 ± 548.1 days. Based on these results, the sensitivity and specificity of the CT scan to detect +TAK and pw = (-TAK) was 100%. In a subgroup of 37 patients that received both a CT scan and the conventional SLT, the sensitivity and specificity of the CT scan was 100% compared with 92% for the SLT (P wounds that do not require surgical intervention and should be considered a valid diagnostic test in the appropriate clinical setting.

    Stab wounds represent the most common cause of penetrating wounds, occurring mainly in case of aggression or suicide attempt. Clinical severity depends on the superficial or penetrating aspect of the wound, its location and damaged organs. Medical management must be known because the vital risk is involved in penetrating wounds. Hemodynamically unstable patients should be operated without delay after performing a chest X-ray and ultrasound Focus assisted sonography for trauma (FAST) to guide the surgery. In the stable patients, the general clinical examination, exploration of the wound and medical imaging detect injuries requiring surgical management. Stab penetrating wounds require close and rapid collaboration between medical teams, tailored to the institution's resources.

    A 14-yr-old female eastern black rhinoceros (Diceros bicornis michaeli) presented with progressive suppurative osteomyelitis in her left hind lateral toe. beta-Hemolytic Streptococcus sp. was isolated. The animal was treated with multiple systemic antibiotics, and topical wound cleansing. Repeated debridements and nail trimmings were performed for 5 mo prior to electing amputation. The toe was surgically amputated under general anesthesia between the first and second phalanges. Analgesia was diffused into the wound topically via a catheter and elastomeric pump. The open amputation site was covered with adherent drapes and a negative-pressure wound therapy device provided vacuum-assisted closure (V.A.C.) for 72 hr. Three months later this animal developed a deep dermal ulcer on the lateral aspect of the right hind limb, at the level of the stifle. Methicillin-resistant Staphylococcus aureus was isolated. The wound was managed by initial daily lavage, followed by 1 mo of V.A.C. therapy, with 72 hr between dressing changes. Clinically, this therapy expedited the formation of healthy granulation tissue and overall healing was accelerated. The animal tolerated the machine and bandage changes well via operant conditioning. The use of negative-pressure wound therapy appeared to shorten time to resolution of slow-healing wounds in black rhinoceros.

    Aim of the study is to describe the application of surgical site infection (SSI) control procedures in general surgery operating rooms of Piedmont region hospitals. A specific data collection form was designed to record information. 54 questionnaires were compiled. Piedmont legislation related to operating rooms' equipment is obeyed in more than 90% of hospitals. Nevertheless, there are some critical aspects than could be risk factors for SSI or that are not useful in order to prevent them: use of UV radiation (11.3%), use of tacky mats at the entrance of the operating room (5.7%), special cleaning of operating rooms after contaminated or dirty operations (73.6%) and routine environmental sampling (10%) that is strongly recommended by ISPESL guideline in disagreement with international recommendations. Steam autoclave is used for surgical instruments sterilization by 100% of hospitals, but only 50% of them performs an annual validation of both autoclave performance and sterilization procedures. The study gave useful information in order to promote some structural modifications and personnel education for efficacious SSI prevention and control.

    Wound care requires an understanding of normal wound healing, causes of delays of wound healing, and the management of wounds. Every wound must be treated as an individual with regard to cause, chronicity, location, and level of microbial contamination, as well as patient factors that affect wound healing. Knowledge of wound care products available and when negative pressure wound therapy and drain placement is appropriate can improve outcomes with wound healing. Inappropriate product use can cause delays in healing. As a wound healing progresses, management of a wound and the bandage material used must evolve.

However, these therapeutic strategies often lead to a reduced neutrophilic granulocyte count or loss of more blood after surgical tumor resection. In this study, we developed a formulation of hemostatic gauze impregnated with sustained-release granulocyte colony-stimulating factor (G-CSF with increasing of the neutrophilic granulocyte count in the blood following chemotherapy and decreasing blood loss after surgical tumor resection.Methods: We designed a formulation with both hemostatic properties and increased neutrophil content to be used in cancer chemotherapy, radiotherapy, and tumor resection, comprising a hemostatic gauze as a scaffold and (G-CSF-loaded dextran nanoparticles coated with polylactic-co-glycolic acid (PLGA solution fabricated by direct spray-painting onto the scaffold and then vacuum-dried at room temperature. The performance of this system was evaluated in vitro and in vivo.Results: Nearly zero-order release of G-CSF was recorded for 12–14 days, and the cumulative release of G-CSF retained over 90% of its bioactivity in a NFS-60 cell line proliferation assay when the scaffold was incubated in phosphate-buffered saline (pH 7.4 at 37°C. The in vivo hemostatic efficacy of this formulation was greater than that of native G-CSF, the scaffold directly spray-painted with G-CSF solution or PLGA organic solution as a coating, or when a blank scaffold was covered with the coating.Conclusion: Our results suggest that this formulation has both hemostatic properties and increased neutrophil activity.Keywords: hemostatic gauze scaffold, granulocyte colony-stimulating factor, bioactivity

    2015-03-01

    Wound healing is a dynamic and complex phenomenon of replacing devitalized tissues in the body. Urethral healing takes place in four phases namely inflammation, proliferation, maturation and remodelling, similar to dermal healing. However, the duration of each phase of wound healing in urology is extended for a longer period when compared to that of dermatology. An ideal wound dressing material removes exudate, creates a moist environment, offers protection from foreign substances and promotes tissue regeneration. A single wound dressing material shall not be sufficient to treat all kinds of wounds as each wound is distinct. This review includes the recent attempts to explore the hidden potential of growth factors, stem cells, siRNA, miRNA and drugs for promoting wound healing in urology. The review also discusses the different technologies used in hospitals to treat wounds in urology, which make use of innovative biomaterials synthesised in regenerative medicines like hydrogels, hydrocolloids, foams, films etc., incorporated with growth factors, drug molecules or nanoparticles. These include surgical zippers, laser tissue welding, negative pressure wound therapy, and hyperbaric oxygen treatment.

    The dental surgeon is often confronted by complications particularly after extraction ofunerupted lower third molars. The most common complication is alveolar periostitis. The healing process after extraction is accompanied by physiologic atrophy of the alveolus involving on the average 30% of bone tissue. Beta-tricalcium phosphate (TCP) is a synthetic material used in medicine to fill up bone defects caused by pathologic processes. The properties of TCP are appropriate for the material to be used as a carrier for drugs, in particular antibiotics. This study was undertaken to determine whether lincomycin applied to the alveolus on TCP carrier can be used to accelerate wound healing and reduce inflammation after surgical extraction of a third molar. We enrolled 80 patients (males and females between the age of 18 and 50 years) who underwent extraction of a third molar at the Department of Dental Surgery, Pomeranian Medical University in Szczecin. Surgical difficulty in the patients according to the Pederson scale corresponded to grade 2 or 3 (medium or high difficulty). The study group consisted of 40 patients who received lincomycin on TCP. Beta-tricalcium phosphate (300-700 microm pores) obtained from the Department of Technology of Ceramics and Refractories, AGH University of Science and Technology in Cracow, was soaked with 500 mg of lincomycin in solution and applied to the dental alveolus after tooth extraction. The alveolus was tightly sutured. The control group comprised 40 patients not treated with lincomycin. The patients reappeared for examination on the first, third, and seventh day after surgery. Attention during follow-up was directed to alveolar periostitis, pain, and trismus. Pain intensity was assessed with the 10-degree Visual Analog Scale (VAS). We analyzed the subjective pain intensity reported during follow-up by the patients. In the study group, 20 patients reported no pain 24 hours after extraction. On the third day after surgery, alveolar

    2014-03-01

    In covering wounds, efforts should include utilization of the safest and least invasive methods with goals of achieving optimal functional and cosmetic outcome. The recent development of advanced wound healing technology has triggered the use of cells to improve wound healing conditions. The purpose of this review is to provide information on clinically available cell-based treatment options for healing of acute and chronic wounds. Compared with a variety of conventional methods, such as skin grafts and local flaps, the cell therapy technique is simple, less time-consuming, and reduces the surgical burden for patients in the repair of acute wounds. Cell therapy has also been developed for chronic wound healing. By transplanting cells with an excellent wound healing capacity profile to chronic wounds, in which wound healing cannot be achieved successfully, attempts are made to convert the wound bed into the environment where maximum wound healing can be achieved. Fibroblasts, keratinocytes, adipose-derived stromal vascular fraction cells, bone marrow stem cells, and platelets have been used for wound healing in clinical practice. Some formulations are commercially available. To establish the cell therapy as a standard treatment, however, further research is needed.

    2016-09-01

    Full Text Available Negative pressure wound therapy has greatly advanced the field of wound healing for nearly two decades, by providing a robust surgical adjunct technique for accelerating wound closure in acute and chronic wounds. However, the application of negative pressure wound therapy in maxillofacial applications has been relatively under utilized as a result of the physical articulations and contours of the head and neck that make it challenging to obtain an airtight seal for different negative pressure wound therapy systems. Adapting negative pressure wound therapies for maxillofacial applications could yield significant enhancement of wound closure in maxillofacial applications. The current review summarizes the basic science underlying negative pressure wound therapy, as well as specific maxillofacial procedures that could benefit from negative pressure wound therapy.

  14. Can we measure surgical resilience?

    Science.gov (United States)

    Graham, David; Becerril-Martinez, Guillermo; Quinto, Lena; Zhao, Dong Fang

    2016-01-01

    Surgical resilience describes psychological resilience within a surgical setting. Within a surgical setting, psychologically resilient patients have improved recovery and wound-healing. The search for biological correlates in resilient patients has led to the hypothesis that certain endogenous biomarkers (namely neuropeptide Y (NPY), testosterone, and dehydroepiandrosterone (DHEA)) are altered in resilient patients. The concept of surgical resilience raises the question of whether enhanced recovery following surgery can be demonstrated in patients with high titres of resilience biomarkers as compared to patients with low titres of resilience biomarkers. To determine the prognostic value of resilience biomarkers in surgical recovery, a cohort of patients undergoing major surgery should initially be psychometrically tested for their resilience levels before and after surgery so that biomarker levels of NPY, testosterone and DHEA can be compared to a validated psychometric test of resilience. The primary outcome would be length of hospital stay with and without an enhanced recovery program. Secondary outcome measures such as complications, time in rehabilitation and readmission could also be included. If the hypothesis is upheld, resilience biomarkers could be used to support more individualised perioperative management and lead to more efficient and effective allocation of healthcare resources.

    Full Text Available A best evidence topic was written according to the structured protocol. The three part question addressed was: [In patients undergoing closure of surgical wounds with sutures] does [keeping the wound dry for the first 48 h after closure] [reduce the incidence of surgical site infections (SSIs]? 4 relevant papers were culled from the literature and appraised. The authors, date, country, population, study type, main outcomes, key results and study weaknesses were tabulated. Current NICE guidelines recommend cleaning surgical wounds with sterile saline only for the first 48 h following skin closure. We found no evidence that washing wounds with tap water during this period increases the incidence of SSIs compared to keeping them dry. Further randomised controlled trials will enable the construction of conclusive systematic reviews and meta-analyses.

    Skin wounds are associated with significant morbidity and mortality. Data are, however, not readily available for benchmarking, to allow prognostic evaluation, and to suggest when involvement of wound-healing experts is indicated. We, therefore, conducted an observational cohort study to investigate wound healing and all-cause mortality associated with different types of skin wounds. Consecutive skin wound patients who received wound care by home-care nurses from January 2010 to December 2011 in a district in Eastern Denmark were included in this study. Patients were followed until wound healing, death, or the end of follow-up on December 2012. In total, 958 consecutive patients received wound care by home-care nurses, corresponding to a 1-year prevalence of 1.2% of the total population in the district. During the study, wound healing was achieved in 511 (53.3%), whereas 90 (9.4%) died. During the first 3 weeks of therapy, healing was most likely to occur in surgical wounds (surgical vs. other wounds: adjusted hazard ratio [AHR] 2.21, 95% confidence interval 1.50-3.23), while from 3 weeks to 3 months of therapy, cancer wounds, and pressure ulcers were least likely to heal (cancer vs. other wounds: AHR 0.12, 0.03-0.50; pressure vs. other wounds: AHR 0.44, 0.27-0.74). Cancer wounds and pressure ulcers were further associated with a three times increased probability of mortality compared with other wounds (cancer vs. other wounds: AHR 3.19, 1.35-7.50; pressure vs. other wounds: AHR 2.91, 1.56-5.42). In summary, the wound type was found to be a significant predictor of healing and mortality with cancer wounds and pressure ulcers being associated with poor prognosis. © 2015 by the Wound Healing Society.

    2017-01-01

    Full Text Available A feared complication of temporary surgical drain placement is from the technical error of accidentally suturing the surgical drain into the wound. Postoperative discovery of a tethered drain can frequently necessitate return to the operating room if it cannot be successfully removed with nonoperative techniques. Formal wound exploration increases anesthesia and infection risk as well as cost and is best avoided if possible. We present a minimally invasive surgical technique that can avoid the morbidity associated with a full surgical wound exploration to remove a tethered drain when other nonoperative techniques fail.

    LENUS (Irish Health Repository)

    2012-02-03

    INTRODUCTION: Vascular endothelial growth factor (VEGF) is a potent mitogenic cytokine which has been identified as the principal polypeptide growth factor influencing endothelial cell (EC) migration and proliferation. Ordered progression of these two processes is an absolute prerequisite for initiating and maintaining the proliferative phase of wound healing. The response of ECs to circulating VEGF is determined by, and directly proportional to, the functional expression of VEGF receptors (KDR\\/Flt-1) on the EC surface membrane. Systemic sepsis and wound contamination due to bacterial infection are associated with significant retardation of the proliferative phase of wound repair. The effects of the Gram-negative bacterial wall components lipopolysaccharide (LPS) and bacterial lipoprotein (BLP) on VEGF receptor function and expression are unknown and may represent an important biological mechanism predisposing to delayed wound healing in the presence of localized or systemic sepsis. MATERIALS AND METHODS: We designed a series of in vitro experiments investigating this phenomenon and its potential implications for infective wound repair. VEGF receptor density on ECs in the presence of LPS and BLP was assessed using flow cytometry. These parameters were assessed in hypoxic conditions as well as in normoxia. The contribution of CD14 was evaluated using recombinant human (rh) CD14. EC proliferation in response to VEGF was quantified in the presence and absence of LPS and BLP. RESULTS: Flow cytometric analysis revealed that LPS and BLP have profoundly repressive effects on VEGF receptor density in normoxic and, more pertinently, hypoxic conditions. The observed downregulation of constitutive and inducible VEGF receptor expression on ECs was not due to any directly cytotoxic effect of LPS and BLP on ECs, as measured by cell viability and apoptosis assays. We identified a pivotal role for soluble\\/serum CD14, a highly specific bacterial wall product receptor, in

    The extremities are the most common anatomic location for gunshot wounds. Because of the prevalence of gunshot injuries, it is important that orthopaedic surgeons are knowledgeable about caring for them. The most common injuries seen with gunshot wounds are those of the soft tissues. Nonsurgical management of patients who have gunshot wounds with minimal soft-tissue disruption has been successfully accomplished in emergency departments for several years; this includes extremity wounds without nerve, intra-articular, or vascular injury. Stable, nonarticular fractures of an extremity have also been successfully treated with either minimal surgical or nonsurgical methods in the emergency department. Indications for surgical treatment include unstable fractures, intra-articular injuries, a significant soft-tissue injury (especially with skin loss), vascular injury, and/or a large or expanding hematoma.

    During the Great War, the French surgeon Alexis Carrel, in collaboration with the English chemist Henry Dakin, devised an antiseptic treatment for infected wounds. This paper focuses on Carrel’s attempt to standardise knowledge of infected wounds and their treatment, and looks closely at the vision of surgical skill he espoused and its difference from those associated with the doctrines of scientific management. Examining contemporary claims that the Carrel–Dakin method increased rather than diminished demands on surgical work, this paper further shows how debates about antiseptic wound treatment opened up a critical space for considering the nature of skill as a vital dynamic in surgical innovation and practice.

    Surgical ethics as a specific discipline is relatively new to many. Surgical ethics focuses on the ethical issues that are particularly important to the care of surgical patients. Informed consent for surgical procedures, the level of responsibility that surgeons feel for their patients' outcomes, and the management of surgical innovation are specific issues that are important in surgical ethics and are different from other areas of medicine. The future of surgical progress is dependent on surgical innovation, yet the nature of surgical innovation raises specific concerns that challenge the professionalism of surgeons. These concerns will be considered in the following pages.

    With the growing demand for more efficient wound care after surgery, there is a necessity to develop a machine learning based image analysis approach to reduce the burden for health care professionals. The aim of this study was to propose a novel approach to recognize wound infection on the postsurgical site. Firstly, we proposed an optimal clustering method based on unimodal-rosin threshold algorithm to extract the feature points from a potential wound area into clusters for regions of interest (ROI). Each ROI was regarded as a suture site of the wound area. The automatic infection interpretation based on the support vector machine is available to assist physicians doing decision-making in clinical practice. According to clinical physicians' judgment criteria and the international guidelines for wound infection interpretation, we defined infection detector modules as the following: (1) Swelling Detector, (2) Blood Region Detector, (3) Infected Detector, and (4) Tissue Necrosis Detector. To validate the capability of the proposed system, a retrospective study using the confirmation wound pictures that were used for diagnosis by surgical physicians as the gold standard was conducted to verify the classification models. Currently, through cross validation of 42 wound images, our classifiers achieved 95.23% accuracy, 93.33% sensitivity, 100% specificity, and 100% positive predictive value. We believe this ability could help medical practitioners in decision making in clinical practice.

    Full Text Available Stab wounds to the buttock are uncommon injuries that are rarely seen in surgical civilian practice. Although, the wound appears trivial, it may cause major life-threatening visceral and vascular injuries. Failure to detect these injuries may lead to serious morbidity and mortality. Herein, we report a patient with a single gluteal stab wound, which was initially sutured and treated conservatively. Two days later, patient developed fever, lower abdominal pain and tenderness with leakage of fecal material from the wound. Exploratory laparotomy revealed an extraperitoneal rectal perforation for which a Hartmann′s procedure was performed. Computed tomography scanning is recommended as a diagnostic tool for stable patients having buttock stab wounds. Diverging colostomy is the standard surgical procedure for extraperitonal rectal injuries that cannot be properly visualized and repaired during a laparotomy. More evidence is needed to assess the fecal non-diversion approach in the treatment of these patients.

    Full Text Available Wound bed preparation has been performed for over two decades, and the concept is well accepted. The ′TIME′ acronym, consisting of tissue debridement, i nfection or inflammation, moisture balance and edge effect, has assisted clinicians systematically in wound assessment and management. While the focus has usually been concentrated around the wound, the evolving concept of wound bed preparation promotes the treatment of the patient as a whole. This article discusses wound bed preparation and its clinical management components along with the principles of advanced wound care management at the present time. Management of tissue necrosis can be tailored according to the wound and local expertise. It ranges from simple to modern techniques like wet to dry dressing, enzymatic, biological and surgical debridement. Restoration of the bacterial balance is also an important element in managing chronic wounds that are critically colonized. Achieving a balance moist wound will hasten healing and correct biochemical imbalance by removing the excessive enzymes and growth factors. This can be achieved will multitude of dressing materials. The negative pressure wound therapy being one of the great breakthroughs. The progress and understanding on scientific basis of the wound bed preparation over the last two decades are discussed further in this article in the clinical perspectives.

    Full Text Available Complex wound is the term used more recently to group those well-known difficult wounds, either chronic or acute, that challenge medical and nursing teams. They defy cure using conventional and simple "dressings" therapy and currently have a major socioeconomic impact. The purpose of this review is to bring these wounds to the attention of the health-care community, suggesting that they should be treated by multidisciplinary teams in specialized hospital centers. In most cases, surgical treatment is unavoidable, because the extent of skin and subcutaneous tissue loss requires reconstruction with grafts and flaps. New technologies, such as the negative pressure device, should be introduced. A brief review is provided of the major groups of complex wounds-diabetic wounds, pressure sores, chronic venous ulcers, post-infection soft-tissue gangrenes, and ulcers resulting from vasculitis.Ferida complexa é uma nova definição para identificar aquelas feridas crônicas e algumas agudas já bem conhecidas e que desafiam equipes médicas e de enfermagem. São difíceis de serem resolvidas usando tratamentos convencionais e simples curativos. Têm atualmente grande impacto sócio-econômico. Esta revisão procura atrair atenção da comunidade de profissionais de saúde para estas feridas, sugerindo que devam ser tratadas por equipe multidisciplinar em centro hospitalar especializado. Na maioria dos casos o tratamento cirúrgico deve ser indicado, uma vez que a perda de pele e tecido subcutâneo é extensa, necessitando de reconstrução com enxertos e retalhos. Nova tecnologia, como uso da terapia por pressão negativa foi introduzido. Breves comentários sobre os principais grupos de feridas complexas: pé diabético, úlceras por pressão, úlceras venosas, síndrome de Fournier e vasculites.

    To explore the relationship between CD4(+) T lymphocyte cell count and prognosis as well as healing of the surgical incision in HIV/AIDS patients who had received operation. Data were collected and analysed retrospectively from 234 HIV/AIDS patients hospitalized at the Beijing Ditan hospital who underwent operation between January 2008 and December 2012. Following factors were taken into consideration that including:age, gender, time and where that anti-HIV(+) was diagnosed, CD4(+)T lymphocyte cell count at the time of operation, part of the body that being operated, typology of incision, different levels of healing on the surgical incision, infection at the incision site, post-operative complications and the prognosis, etc. Wilcoxon rank sum test, χ(2) test, Kruskal-Wallis H test and Spearman rank correlation were used for statistical analysis to compare the different levels on healing of the incision in relation to the different CD4(+)T lymphocyte cell counts. Rates of level A healing under different CD4(+)T cell counts were also compared. 1) Among the 234 patients including 125 males and 109 females, the average age was 36.17±11.56 years old. Time after discovery of anti-HIV(+)was between 0 and 204 months. The medium CD4(+)T cell count was 388.5 cell/µl; 23.93% of the patients having CD4(+)T lymphocyte cell counts as different organs affected at the time of operation, due to 48 different kinds of illness. 21.37% of the operations belonged to class I incision, 49.57% was class II incision and 29.06% was class III incision. 86.32% of the incisions resulted in level A healing, 12.51% resulted in level B and 1.71% in level C. 4.27% of the patients developed post-operative complications. Differences between level A healing and level B or C healing in terms of CD4(+)T lymphocyte cell count were not significant (P > 0.05). There was no statistically significant difference on the CD4(+) T lymphocyte count in patients with or without postoperative complications

    A novel approach for the immediate sealing of traumatic wounds is under development. A portable microwave generator and handheld antenna are used to seal wounds, binding the edges of the wound together using a biodegradable protein sealant or solder. This method could be used for repairing wounds in emergency settings by restoring the wound surface to its original strength within minutes. This technique could also be utilized for surgical purposes involving solid visceral organs (i.e., liver, spleen, and kidney) that currently do not respond well to ordinary surgical procedures. A miniaturized microwave generator and a handheld antenna are used to deliver microwave energy to the protein solder, which is applied to the wound. The antenna can be of several alternative designs optimized for placement either in contact with or in proximity to the protein solder covering the wound. In either case, optimization of the design includes the matching of impedances to maximize the energy delivered to the protein solder and wound at a chosen frequency. For certain applications, an antenna could be designed that would emit power only when it is in direct contact with the wound. The optimum frequency or frequencies for a specific application would depend on the required depth of penetration of the microwave energy. In fact, a computational simulation for each specific application could be performed, which would then match the characteristics of the antenna with the protein solder and tissue to best effect wound closure. An additional area of interest with potential benefit that remains to be validated is whether microwave energy can effectively kill bacteria in and around the wound. Thus, this may be an efficient method for simultaneously sterilizing and closing wounds.

    Mitogen-activated protein kinase (MAPK) phosphatase-3 (MKP-3) and its substrates (extracellular signal-regulated kinase [ERK] and p38) play an important role in pathophysiological mechanisms of acute postoperative and chronic neuropathic pain in the spinal cord. This study aimed to understand the role of MKP-3 and its target MAPKs at the site of surgical incision in nociceptive behavior. Wild-type (WT) and MKP-3 knockout (KO) mice underwent unilateral plantar hind paw incision. Mechanical allodynia was assessed by using von Frey filaments. Peripheral ERK-1/2 and p38 phosphorylation were measured by Western blot. Cell infiltration was determined using hematoxylin and eosin histological staining. Peripheral phosphorylated ERK-1/2 (p-ERK-1/2) inhibition was performed in MKP-3 KO mice. In WT mice, mechanical hypersensitivity was observed on postoperative day 1 (0.69±0.17 g baseline vs 0.13±0.08 g day 1), which resolved normally by postoperative day 12 (0.46±0.08 g, N=6). In MKP-3 KO mice, this hypersensitivity persisted at least 12 days after surgery (0.19±0.06 g; N=6). KO mice displayed higher numbers of infiltrating cells (51.4±6 cells/0.1 mm2) than WT mice (8.7±1.2 cells/0.1 mm2) on postoperative day 1 (vs 5–6 cells/0.1 mm2 at baseline) that returned to baseline 12 days after surgery (10–12 cells/0.1 mm2). In WT mice, peripheral p-p38 and p-ERK-1/2 expression increased (5- and 3-fold, respectively) on postoperative days 1 and 5, and returned to basal levels 7–12 days after surgery (N=3 per group). Peripheral p-p38 levels in MKP-3 KO mice followed a similar expression pattern as WT mice. Peripheral p-ERK-1/2 levels in MKP-3 KO mice remained elevated 12 days after surgery (2.5-fold, N=3 per group). Administration of PD98059 (MEK inhibitor, N=8, vehicle N=9) reduced p-ERK-1/2 expression in the incised tissue and blocked hypersensitivity in MKP-3 KO mice (N=6). The findings of this study suggest that MKP-3 is pivotal for normal resolution of acute

    Telemedical wound care is one of the applications of teledermatology. We present our experience using telemedicine in the successful assessment and treatment of three patients with hard-to-heal ulcers. Three patients were seen at the PEMEX General Hospital in Veracruz, Mexico. The first patient was a 53-year-old man with hypertension, morbid obesity, chronic venous insufficiency, recurrent erysipelas, leg ulcers and lymphoedema. There was one ulcer on his left lower leg (20 x 10 cm) and one on his right leg (9 x 7 cm). The second patient was a 73-year-old woman with class III obesity and ulcers in her right leg, secondary to surgical debridement of bullous erysipelas. The third patient was a 51-year-old female with rheumatoid arthritis with one ulcer on each leg and chronic lymphostasis. Photographs with a digital camera were taken and sent weekly via email to a wound care specialist in Mexico City. The photographs allowed the expert to diagnose and evaluate the chronic wounds periodically. In the present cases, telemedicine allowed us to have a rapid evaluation, diagnosis and treatment. The images were of enough quality to be useful and small enough to be sent via regular email to the remote physician who immediately gave his feedback. The expert was confident to give therapeutic recommendations in this way, and we considered this method to be very cost-effective, saving the patient and the health care system, especially in transportation.

    Successful innovative 'leaps' in surgical technique have the potential to contribute exponentially to surgical advancement, and thereby to improved health outcomes for patients. Such innovative leaps often occur relatively spontaneously, without substantial forethought, planning, or preparation. This feature of surgical innovation raises special challenges for ensuring sufficient evaluation and regulatory oversight of new interventions that have not been the subject of controlled investigatory exploration and review. It is this feature in particular that makes early-stage surgical innovation especially resistant to classification as 'research', with all of the attendant methodological and ethical obligations--of planning, regulation, monitoring, reporting, and publication--associated with such a classification. This paper proposes conceptual and ethical grounds for a restricted definition according to which innovation in surgical technique is classified as a form of sui generis surgical 'research', where the explicit goal of adopting such a definition is to bring about needed improvements in knowledge transfer and thereby benefit current and future patients.

    Full Text Available Scar formation is an inevitable consequence of wound healing from either a traumatic or a surgical intervention. The aesthetic appearance of a scar is the most important criteria to judge the surgical outcome. An understanding of the anatomy and wound healing along with experience, meticulous planning and technique can reduce complications and improve the surgical outcome. Scar revision does not erase a scar but helps to make it less noticeable and more acceptable. Both surgical and non-surgical techniques, used either alone or in combination can be used for revising a scar. In planning a scar revision surgeon should decide on when to act and the type of technique to use for scar revision to get an aesthetically pleasing outcome. This review article provides overview of methods applied for facial scar revision. This predominantly covers surgical methods.

    A wound is damage of a tissue usually caused by laceration of a membrane, generally the skin. Wound healing is accomplished in three stages in healthy individuals, including inflammatory, proliferative, and remodeling stages. Healing of wounds normally starts from the inflammatory phase and ends up in the remodeling phase, but chronic wounds remain in an inflammatory stage and do not show progression due to some specific reasons. Chronic wounds are classified in different categories, such as diabetic foot ulcer (DFU), venous leg ulcers (VLU) and pressure ulcer (PU), surgical site infection (SSI), abscess, or trauma ulcers. Globally, the incidence rate of DFU is 1-4 % and prevalence rate is 5.3-10.5 %. However, colonization of pathogenic bacteria at the wound site is associated with wound chronicity. Most chronic wounds contain more than one bacterial species and produce a synergetic effect that results in previously non-virulent bacterial species becoming virulent and causing damage to the host. While investigating bacterial diversity in chronic wounds, Staphylococcus, Pseudomonas, Peptoniphilus, Enterobacter, Stenotrophomonas, Finegoldia, and Serratia were found most frequently in chronic wounds. Recently, it has been observed that bacteria in chronic wounds develop biofilms that contribute to a delay in healing. In a mature biofilm, bacteria grow slowly due to deficiency of nutrients that results in the resistance of bacteria to antibiotics. The present review reflects the reasons why acute wounds become chronic. Interesting findings include the bacterial load, which forms biofilms and shows high-level resistance toward antibiotics, which is a threat to human health in general and particularly to some patients who have acute wounds.

    Hidradenitis suppurativa (HS) is a chronic, burdensome, debilitating disease of the hair follicle. It presents with recurrent painful inflamed and noninflamed lesions usually in specific body areas such as axillary, inguinal, perineal, and genital areas. It is associated with a large range of other diseases and conditions, such as obesity, arthropathy, inflammatory bowel diseases, and sqaumous cell carcinoma. Medical therapy may be systemic or topical, mainly based on antibiotics, retinoids, hormones and immunosuppressive drugs, including biological therapies. Surgical and laser therapies may be a valid therapeutic approach in order to treat locally recurring lesions. The aim of this article is to review the wound healing options after skin excision and laser treatments, with a focus on lesions left to heal by secondary intention, analyzing the efficacy of moist wound dressings, negative pressure wound therapy, bioactive dressings, such as platelet-rich plasma gel and hylarunoic acid scaffold, or autologous keratinocyte suspension in platelet concentrate and skin-grafting tecniques.

    Full Text Available Introduction: Decision for cesarean section may lead to the stress for women in delivery. Stress response requires longer recovery time in post cesarean section patients. Most of patients who experience stress before and after surgical is associated with wound healing delay. When this condition continues, the wound will have a higher risk of infection. The objective of this study was to analyze correlation between stress and wound healing phase in post cesarean section patients. Method: A cross sectional design was used in this study. The population were women with cesarean section, both elective or emergency, in Delivery Room I RSU Dr. Soetomo Surabaya. Samples were recruited by using purposive sampling, with 28 samples who met to the inclusion criterias. The observed variables were stress and wound healing phase in post cesarean section patient. Stress data were collected by interview and wound healing measurement done by observation on the 3rd day post cesarean section. Result: The result showed that women with stress experience wound healing delay. The characteristic of wound healing delay was prolonged on inflammation phase, nevertheless there was presence of granulation tissue. Spearman’s rho correlation showed that correlation value r=0.675 with p=0.000. Discussion: It can be concluded that there was strong significant correlation between stress and wound healing phase in post cesarean section patients. It is important to give this information to the patients with cesarean section in order to prevent stress and delay in wound healing phase.

    The purpose of this study was to identify the predominant client factors and comorbidities that affected the time taken for wounds to heal. A prospective study design used the Mobile Wound Care (MWC) database to capture and collate detailed medical histories, comorbidities, healing times and consumable costs for clients with wounds in Gippsland, Victoria. There were 3,726 wounds documented from 2,350 clients, so an average of 1.6 wounds per client. Half (49.6%) of all clients were females, indicating that there were no gender differences in terms of wound prevalence. The clients were primarily older people, with an average age of 64.3 years (ranging between 0.7 and 102.9 years). The majority of the wounds (56%) were acute and described as surgical, crush and trauma. The MWC database categorized the elements that influenced wound healing into 3 groups--factors affecting healing (FAH), comorbidities, and medications known to affect wound healing. While there were a multitude of significant associations, multiple linear regression identified the following key elements: age over 65 years, obesity, nonadherence to treatment plan, peripheral vascular disease, specific wounds associated with pressure/friction/shear, confirmed infection, and cerebrovascular accident (stroke). Wound healing is a complex process that requires a thorough understanding of influencing elements to improve healing times.© 2015 by the Wound Healing Society. © 2015 by the Wound Healing Society.

    To provide a critical review of methods used to assess human wound healing in psychological research and related disciplines, in order to guide future research into psychological influences on wound healing. Acute wound models (skin blister, tape stripping, skin biopsy, oral palate biopsy, expanded polytetrafluoroethylene tubing), surgical wound healing assessment methods (wound drains, wound scoring), and chronic wound assessment techniques (surface area, volumetric measurements, wound composition, and assessment tools/scoring systems) are summarized, including merits, limitations, and recommendations. Several dermal and mucosal tissue acute wound models have been established to assess the effects of psychological stress on the inflammatory, proliferative, and repair phases of wound healing in humans, including material-based models developed to evaluate factors influencing post-surgical recovery. There is a paucity of research published on psychological factors influencing chronic wound healing. There are many assessment techniques available to study the progression of chronic wound healing but many difficulties inherent to long-term clinical studies. Researchers need to consider several design-related issues when conducting studies into the effects of psychological stress on wound healing, including the study aims, type of wound, tissue type, setting, sample characteristics and accessibility, costs, timeframe, and facilities available. Researchers should consider combining multiple wound assessment methods to increase the reliability and validity of results and to further understand mechanisms that link stress and wound healing. ©2010 The British Psychological Society.

    Negative-pressure wound therapy is a newly developed, noninvasive technique to manage a wide variety of wounds. This novel therapy was successfully used to heal the wound after open-window thoracostomy without surgical closure. A 46-year-old woman was admitted to hospital because of a painful mass on the right side of her chest. Radiological findings revealed an abscess on the right chest wall that had ruptured into the right lung and caused empyema. Antibiotic therapy did not yield sufficient improvement. Open-window thoracostomy was performed to achieve a sterile pleural space, and negative-pressure wound therapy was then applied. The pleural space was reduced, and the patient was discharged home with self-administered wound care. The wound healed completely in 5 months without any need for surgical closure.

    Full Text Available Heidi Sandoz Accelerate CIC, Mile End Hospital, London, UK Abstract: Negative pressure wound therapy (NPWT, also known as topical negative pressure therapy, has been increasingly used in health care for the management of a wide variety of wounds over the last 2–3 decades. It is an advanced therapy that can be helpful to accelerate wound healing in both acute and chronic wounds by delivering negative pressure (suction to the wound bed. More recent advancements in the application of NPWT have provided clinicians with wider choices of utilization. There are now devices available that can deliver irrigation to the wound bed, be used for closed surgical incisions, or are disposable and highly portable. Systematic reviews considering NPWT have been published previously. These usually focus on one wound group or device and fail to offer practical clinical guidance due to the scrutiny offered to the evidence via a systematic review process. Here, an overview of the history of NPWT, the varieties of device available, their wide clinical application, and the evidence to support its use are explored in a pragmatic way.

  8. Burn Wound Mucormycosis: A Case Study on Poor Wound Healing.

    Science.gov (United States)

    Stanistreet, Bryan; Bell, Derek

    Mucormycosis is a rare, rapidly progressive and often fatal fungal infection. The rarity of the condition lends itself to unfamiliarity, delayed treatment, and poor outcomes. Diagnosis of fungal infections early enough to enable appropriate treatment occurs in less than half of affected patients. A 56-year-old male with a history of diabetes mellitus II, hepatitis C, and intravenous drug abuse was involved in a rollover motor vehicle accident. He sustained circumferential partial and full-thickness burns to his lower extremities with 20% BSA burns. He ultimately required a below-knee amputation of his right lower extremity due to poor wound healing and nonviability of the soft tissue and foot. Debridement found muscle fibers that were necrotic and purulent. Pathology revealed Mucor species with extensive vascular invasion. This case and discussion highlights the importance of maintaining vigilance for mycotic infections and acting appropriately when there are concerning signs and symptoms of serious wound complications. Caretakers of severe trauma patients should have a high level of suspicion for complications and be cognizant of the American Burn Association's guidelines for systemic inflammatory response syndrome and sepsis. Progressive necrosis outside the confines of the original burn wound should raise concern for impaired wound healing, an immunocompromised state or an underlying infection.

    Full Text Available Problem Statement: Abdominoplasty has become an increasingly popular procedure. Risk factors affecting wound complications of abdominoplasty are not adequately defined in literature. Identification of these risk factors is crucial for better patient’s selection and counseling. The objectives of this study were to determine wound complication rate following abdominoplasty and to examine the relationship of a set of possible risk factors with the incidence of complications. Approach: We studied 116 patients (107 women and 9 men who underwent abdominoplasty at Jordan University Hospital, between June 1997 and June 2007. Data were collected from patients’ medical records and analyzed to determine types and rates of surgical wound complications. Fourteen possible risk factors were investigated using logistic regression analysis to evaluate their relationship with the occurrence of wound complications. Risk factors examined were: age, sex, body mass index, parity number, smoking history, history of diabetes mellitus, previous gastroplasty for morbid obesity, previous abdominal surgical scars, type of abdominoplasty, plication of recti, hernia repair, operative time and operative blood loss. Results: A total of 29 patients (two males and 27 females (25% had wound complications. The most common complication was seroma. It was encountered in 15 cases (12.9%. Six patients (5.2% had wound infection. Partial skin necrosis was encountered in four cases (3.4 %. Two patients (1.7% developed wound dehiscence and two patients (1.7% had hematoma. The only factors significantly increased the complication rate were: increased body mass index (p = 0.002 and history of smoking (p = 0.004. Conclusions and Recommendations: This study confirms the adverse effect of overweight and cigarette smoking on the incidence of wound complication rate following abdominoplasty. We recommend that overweight patients and smokers undergoing abdominoplasty should be adequately

    Providing improved health care for wound, burn and surgical patients is a major goal for enhancing patient well-being, in addition to reducing the high cost of current health care treatment. The introduction of new and novel biomaterials and biomedical devices is anticipated to have a profound effect on the future improvement of many deleterious health issues. This publication will discuss the development of novel non-stinging liquid adhesive bandages in healthcare applications developed by Rochal Industries. The scientists/engineers at Rochal have participated in commercializing products in the field of ophthalmology, including rigid gas permeable contact lenses, soft hydrogel contact lenses, silicone hydrogel contact lenses, contact lens care solutions and cleaners, intraocular lens materials, intraocular controlled drug delivery, topical/intraocular anesthesia, and in the field of wound care, as non-stinging, spray-on liquid bandages to protect skin from moisture and body fluids and medical adhesive-related skin injuries. Current areas of entrepreneurial activity at Rochal Industries pertain to the development of new classes of biomaterials for wound healing, primarily in regard to microbial infection, chronic wound care, burn injuries and surgical procedures, with emphasis on innovation in product creation, which include cell-compatible substrates/scaffolds for wound healing, antimicrobial materials for opportunistic pathogens and biofilm reduction, necrotic wound debridement, scar remediation, treatment of diabetic ulcers, amelioration of pressure ulcers, amelioration of neuropathic pain and adjuvants for skin tissue substitutes.

    Chronic wounds including diabetic foot ulcers, pressure ulcers, and venous leg ulcers are a worldwide health problem. It has been speculated that bacteria colonizing chronic wounds exist as highly persistent biofilm communities. This research examined chronic and acute wounds for biofilms and characterized microorganisms inhabiting these wounds. Chronic wound specimens were obtained from 77 subjects and acute wound specimens were obtained from 16 subjects. Culture data were collected using standard clinical techniques. Light and scanning electron microscopy techniques were used to analyze 50 of the chronic wound specimens and the 16 acute wound specimens. Molecular analyses were performed on the remaining 27 chronic wound specimens using denaturing gradient gel electrophoresis and sequence analysis. Of the 50 chronic wound specimens evaluated by microscopy, 30 were characterized as containing biofilm (60%), whereas only one of the 16 acute wound specimens was characterized as containing biofilm (6%). This was a statistically significant difference (p<0.001). Molecular analyses of chronic wound specimens revealed diverse polymicrobial communities and the presence of bacteria, including strictly anaerobic bacteria, not revealed by culture. Bacterial biofilm prevalence in specimens from chronic wounds relative to acute wounds observed in this study provides evidence that biofilms may be abundant in chronic wounds.

    Full Text Available Wound closure is a part of any surgical procedure and the objective of laceration repair or incision closure is to approximate the edges of a wound so that natural healing process may occur. Over the years new biomaterials have been discovered as an alternate to conventional suture materials. Cyanoacrylate bioadhesives are one among them. They carry the advantages of rapid application, patient comfort, resistance to infection, hemostatic properties, and no suture removal anxiety. Hence this study was undertaken to study the effect of long chain cyanoacrylate as an adhesive for intraoral wound closure and also to explore its hemostatic and antibacterial effects. Isoamyl-2-cyanoacrylate (AMCRYLATE was used as the adhesive in the study. In conclusion isoamyl cyanoacrylate can be used for intraoral wound closure, as an alternative to sutures for gluing the mucoperiosteum to bone, for example, after impaction removal, periapical surgeries, and cleft repair. Its hemostatic and antibacterial activity has to be further evaluated.

    1. A method for measuring the area of a wound not geometric in form is described. 2. The rate of cicatrization of a wound is greater at the beginning than at the end of the period of repair. It depends on the area rather than on the age of the wound. There is a constant relation between the size of a wound and the rate of cicatrization. The larger the wound the greater is the rate of cicatrization. Two wounds of different size have a tendency to become equal. 3. The rate is proportional to the area, but diminishes less rapidly than the area. 4. The process of contraction is the more important factor in the repair of a wound. Epidermization completes the work of contraction. After the wound is healed, the cicatrix as a rule expands. 5. The curve representing the diminution of the size of an aseptic wound while it cicatrizes is regular and geometric. PMID:19868052

    Extremely low frequency electromagnetic fields (ELF) were configured to interact with peripheral blood mononuclear cells (PBMC). These ELF were applied in the arm to five patients with chronic wounds resistant to medical and surgical treatment. Wound healing began in all patients during the first two weeks after ELF exposure permiting their previously unresponsive chronic wounds to function as internal controls. All lesions were cured or healed >70% in less than four months. Systemic effects were explained by ELF activation of PBMC and their transportation through the blood to the affected site. This therapy is effective in selected patients with chronic wounds.

    Wound healing is considered to be particularly important after surgical procedures, and the most important wounds related to surgical procedures are incisional, excisional, and punch wounds. Research is ongoing to identify methods to heal non-closed wounds or to accelerate wound healing; however, wound healing is a complex process that includes many biological and physiological events, and it is affected by various local and systemic factors, including diabetes mellitus, infection, ischemia, and aging. Different cell types (such as platelets, macrophages, and neutrophils) release growth factors during the healing process, and platelet-derived growth factor is a particularly important mediator in most stages of wound healing. This review explores the relationship between platelet-derived growth factor and wound healing.

    Advanced therapeutic dressings that take active part in wound healing to achieve rapid and complete healing of chronic wounds is of current research interest. There is a desire for novel strategies to achieve expeditious wound healing because of the enormous financial burden worldwide. This paper reviews the current state of wound healing and wound management products, with emphasis on the demand for more advanced forms of wound therapy and some of the current challenges and driving forces behind this demand. The paper reviews information mainly from peer-reviewed literature and other publicly available sources such as the US FDA. A major focus is the treatment of chronic wounds including amputations, diabetic and leg ulcers, pressure sores, and surgical and traumatic wounds (e.g., accidents and burns) where patient immunity is low and the risk of infections and complications are high. The main dressings include medicated moist dressings, tissue-engineered substitutes, biomaterials-based biological dressings, biological and naturally derived dressings, medicated sutures, and various combinations of the above classes. Finally, the review briefly discusses possible prospects of advanced wound healing including some of the emerging physical approaches such as hyperbaric oxygen, negative pressure wound therapy and laser wound healing, in routine clinical care.

    2012-02-01

    Gunshot wounds are among the most complex traumatic lesions encountered in forensic pathology. At the time of autopsy, careful scrutiny of the wounds is essential for correct interpretation of the lesions. Complementary pathological analysis has many interests: differentiation between entrance and exit wounds, estimation of firing distance, differentiation between vital and post mortem wounds and wounds dating. In case of multiple headshots, neuropathological examination can provide arguments for or against suicide. Sampling of gunshot wounds at autopsy must be systematic. Pathological data should be confronted respectively to autopsy and death scene investigation data and also ballistic studies. Forensic pathologist must be aware of the limits of optic microscopy.

    Human fibroblast-derived dermis skin substitute is a well-studied treatment for diabetic foot ulcers; however, no case series currently exist for its use in healing postoperative wounds of the lower extremity. A retrospective analysis was conducted on 32 lower extremity postoperative wounds treated weekly with human fibroblast-derived dermis skin substitute. Postoperative wounds were defined as a wound resulting from an open partial foot amputation, surgical wound dehiscence, or nonhealing surgical wound of the lower extremity. Wound surface area was calculated at 4 and 12 weeks or until wound closure if prior to 12 weeks. Postoperative wounds treated with weekly applications showed mean improvement in surface area reduction of 63.6% at 4 weeks and 96.1% at 12 weeks. More than 56% of all wounds healed prior to the 12-week endpoint. Additionally, only one adverse event was noted in this group. This retrospective review supports the use of human fibroblast-derived dermis skin substitute in the treatment of postoperative lower extremity wounds. This advanced wound care therapy aids in decreased total healing time and increased rate of healing for not only diabetic foot wounds but also postoperative wounds of the lower extremity, as demonstrated by this retrospective review.

    Full Text Available BACKGROUND Large, complicated wounds pose a significant surgical problem. Negative pressure wound therapy is one of several methods enabling to obtain better treatment results in case of open infected wounds.1,2 The use of negative pressure therapy enables to obtain a reduction in the number of bacteria which significantly reduces the number of complications.3,4,5 AIMS AND OBJECTIVES: To review the Role of VAC in wound healing in Orthopaedics. MATERIALS AND METHODS The cases presented in this study are those who were admitted in King George Hospital in the time period from January 2014 to August 2015. This is a prospective interventional study. In this study, 15 patients were assigned to the study group (Negative Pressure Wound Therapy- NPWT based on their willingness for undergoing treatment. OBSERVATIONS AND RESULTS 12 males and 3 females are involved in the study. There is decrease in the mean wound area from 64 cm2 to 38 cm2 . There is decrease in the duration of hospital stay. Finally, wound is closed by SSG or secondary suturing. DISCUSSION NPWT is known to reduce bacterial counts, although they remain colonised with organisms. Wounds covered with NPW dressing are completely isolated from the environment, thereby reduces cross infection. In our series, we had 73.3% (11 cases excellent results and 26.7% (4 cases good results and no poor results. As interpretation with results, VAC therapy is effective mode of adjuvant therapy for the management of infected wounds. CONCLUSION VAC has been proven to be a reliable method of treating a variety of infected wounds. It greatly increases the rate of granulation tissue formation and lowers bacterial counts to accelerate wound healing. It can be used as a temporary dressing to prepare wounds optimally prior to closure or as a definitive treatment for nonsurgical and surgical wounds. VAC is now being used in a multitude of clinical settings, including the treatment of surgical wounds, infected wounds

    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    Thomas K. Hunt is a general surgeon. Through his basic wound healing research and clinical work with wound patients he has been a great inspiration for my work in wound healing. In order to fulfill Dr. Hunt's vision, the clinical wound healing arena must be organized in an optimal way, and this article focuses on different options. Multidisciplinary wound care teams or centers focusing on all types of problem wounds have proved to be most effective at providing treatment and care for patients with problem wounds. The ultimate model is an outpatient clinic and an inpatient ward joined within a departmental structure, which represents an integrated part of an accepted national expert program on wound healing. Different types of center models can be established with different advantages and disadvantages. Currently, the wound care arena is being organized in Denmark and the model is described in this article. Of all specialties involved in treatment of wounds, surgery is of vital importance. "Wound healing is the keystone on which surgery is founded" (Thomas K. Hunt). This has long been understood in relation to acute wounds, while the importance of surgery in the treatment of chronic wounds has been less widely recognized. Surgical procedures directly related to the wound consist of debridement of all types of problem wounds and, in more specialized procedures such as skin transplantation, different types of flap constructions, bone surgery, and tendo-Achilles lengthening. Arterial reconstruction is a type of surgery that indirectly, through improved tissue perfusion, improves healing of problem wounds. This study concludes that multidisciplinary specialized wound healing concepts integrated into the national health care system as accepted expert functions would be the ideal way to organize wound healing to best benefit patients and society. Emphasis is on the importance of surgical procedures in wound healing and care. The models described can be applied with minor

    Significance: Although the wound healing cascade is similar in many tissues, in the gastrointestinal tract mucosal healing is critical for processes such as inflammatory bowel disease and ulcers and healing of the mucosa, submucosa, and serosal layers is needed for surgical anastomoses and for enterocutaneous fistula. Failure of wound healing can result in complications including infection, prolonged hospitalization, critical illness, organ failure, readmission, new or worsening enterocutaneous fistula, and even death. Recent Advances: Recent advances are relevant for the role of specific micronutrients, such as vitamin D, trace elements, and the interplay between molecules with pro- and antioxidant properties. Our understanding of the role of other small molecules, genes, proteins, and macronutrients is also rapidly changing. Recent work has elucidated relationships between oxidative stress, nutritional supplementation, and glucose metabolism. Thresholds have also been established to define adequate preoperative nutritional status. Critical Issues: Further work is needed to establish standards and definitions for measuring the extent of wound healing, particularly for inflammatory bowel disease and ulcers. In addition, a mounting body of evidence has determined the need for adequate preoperative nutritional supplementation for elective surgical procedures. Future Directions: A large portion of current work is restricted to model systems in rodents. Therefore, additional clinical and translational research is needed in this area to promote gastrointestinal wound healing in humans, particularly those suffering from critical illness, patients with enterocutaneous fistula, inflammatory bowel disease, and ulcers, and those undergoing surgical procedures.

    Cutaneous wound healing is a complex and well-coordinated interaction between inflammatory cells and mediators, establishing significant overlap between the phases of wound healing. Wound healing is divided into three major phases: inflammatory phase, proliferative phase, and remodeling phase. Unlike the acute wound, the nonhealing wound is arrested in one of the phases of healing, typically the inflammatory phase. A systematic approach to the management of the chronic nonhealing wound emphasizes three important elements of wound bed preparation in chronic wounds: debridement, moisture, and countering bacterial colonization and infection. In this article, wound-healing process and new approaches to the topical wound care have been reviewed.

    Combat wounds are sometimes confounded by healing complications that are not as prevalent in civilian wounds due to their high energy etiology. One complication of wound healing is dehiscence, where a surgically closed wound reopens after closure. This complication can have serious consequences for the patient, but knowledge about the molecular composition of the wound bed beyond what is readily visible may help clinicians mitigate these complications. It is necessary to develop techniques that can be used in vivo to assess and predict wound healing pointof- care so that care-takers can decide the best way to make informed clinical decisions regarding their patient's healing. Raman spectroscopy is a perfect candidate for predicting wound healing due to its ability to provide a detailed molecular fingerprint of the wound bed noninvasively. Here, we study the spectral correlation index, a measure of orthogonality, with ten reference tissue components to stratify wounds based on how they heal. We analyze these indexes over time to show the modulation of these tissue components over the wound healing process. Results show that qualitative observation of the spectra cannot reveal major differences between the dehisced and normal healing wounds, but the spectral correlation index can. Analysis of the spectral correlations across the wound healing process demonstrates the changes throughout the wound healing process, showing that early differences in tissue components may portend wound healing. Furthermore, Raman spectroscopy coupled with the spectral correlation index presents as a possible point-of-care tool for enabling discrimination of wounds with impaired healing.

    Full Text Available Regulated negative pressure-assisted wound therapy (RNPT should be regarded as a state-of-the-art technology in wound treatment and the most important physical, nonpharmaceutical, platform technology developed and applied for wound healing in the last two decades. RNPT systems maintain the treated wound′s environment as a semi-closed, semi-isolated system applying external physical stimulations to the wound, leading to biological and biochemical effects, with the potential to substantially influence wound-host interactions, and when properly applied may enhance wound healing. RNPT is a simple, safe, and affordable tool that can be utilized in a wide range of acute and chronic conditions, with reduced need for complicated surgical procedures, and antibiotic treatment. This technology has been shown to be effective and safe, saving limbs and lives on a global scale. Regulated, oxygen-enriched negative pressure-assisted wound therapy (RO-NPT is an innovative technology, whereby supplemental oxygen is concurrently administered with RNPT for their synergistic effect on treatment and prophylaxis of anaerobic wound infection and promotion of wound healing. Understanding the basic science, modes of operation and the associated risks of these technologies through their fundamental clinical mechanisms is the main objective of this review.

    A multitude of topical wound treatments are used today. Although it is well established that the micro-environment of healing wounds can be altered to improve healing, it is difficult to measure the subtle differences in outcome where therapies are compared. We compared wound healing properties between four different topical agents in surgically incised wounds in a pig model. The four topical agents, 5% Povidone-Iodine cream, 1% Silver-Sulphadiazine, 2% Mupirocin, and 1% Silver-Sulphadiazine plus 1mg/100g recombinant-human epithelial growth factor (EGF) were randomly assigned to four test animals each. Test agents were compared to each other and to untreated controls. We investigated existing and new methodologies of measurement of wound healing: clinical and histological visual scoring systems, immuno-histochemistry, and computerized image analysis of the wounds on days 3, 7, and 28. All agents were found to have improved healing rates with better cellular architecture. Healing was faster, histological appearance resembled normal architecture sooner, clinical appearance improved, mitotic activity was stimulated and more collagen was deposited in comparison to the wounds with no agents. EGF-treated wounds showed an increased rate of epithelisation, but the rate of healing did not correlate well with evaluation of cosmetic outcome. Topical agents improve all aspects of wound healing. The addition of a human recombinant EGF to Silver-Sulphadiazine increases epithelial growth and amounts of collagen in the regenerating wounds at day 7. Copyright © 2016. Published by Elsevier Ltd.

  8. Biofilm in wound care.

    2015-03-01

    A biofilm can be described as a microbial colony encased in a polysaccharide matrix which can become attached to a wound surface. This can affect the healing potential of chronic wounds due to the production of destructive enzymes and toxins which can promote a chronic inflammatory state within the wound. Biofilms can be polymicrobial and can result in delayed wound healing and chronic wound infection resistant to antibiotics, leading to prolonged hospitalisation for some patients. There appears to be a correlation between biofilms and non-healing in chronic wounds. It is suggested that biofilms are a major player in the chronicity of wounds. They are a complex concept to diagnose and management needs to be multifactorial.

    This study aimed to elucidate the optimum usage parameters of low reactive-level laser therapy (LLLT) in a rat incisional wound model. In Sprague-Dawley rats, surgical wounds of 15-mm length were made in the dorsal thoracic region. They were divided into groups to receive 660-nm diode laser irradiation 24 h after surgery at an energy density of 0 (control), 1, 5, or 10 J/cm(2). Tissue sections collected on postoperative day 3 were stained with hematoxylin-eosin and an antibody for ED1 to determine the number of macrophages around the wound. Samples collected on day 7 were stained with hematoxylin-eosin and observed via polarized light microscopy to measure the area occupied by collagen fibers around the wound; day 7 skin specimens were also subjected to mechanical testing to evaluate tensile strength. On postoperative day 3, the numbers of macrophages around the wound were significantly lower in the groups receiving 1 and 5 J/cm(2) irradiation, compared to the control and 10 J/cm(2) irradiation groups (p healing tissues from 1 and 5 J/cm(2) irradiation groups, compared to the control group (p wound healing in a rat incisional wound model. However, a higher radiation energy density yielded no significant enhancement.

    Corneal wound healing is a complex process involving cell death, migration, proliferation, differentiation, and extracellular matrix remodeling. Many similarities are observed in the healing processes of corneal epithelial, stromal and endothelial cells, as well as cell-specific differences. Corneal epithelial healing largely depends on limbal stem cells and remodeling of the basement membrane. During stromal healing, keratocytes get transformed to motile and contractile myofibroblasts largely due to activation of transforming growth factor-β (TGF-β) system. Endothelial cells heal mostly by migration and spreading, with cell proliferation playing a secondary role. In the last decade, many aspects of wound healing process in different parts of the cornea have been elucidated, and some new therapeutic approaches have emerged. The concept of limbal stem cells received rigorous experimental corroboration, with new markers uncovered and new treatment options including gene and microRNA therapy tested in experimental systems. Transplantation of limbal stem cell-enriched cultures for efficient re-epithelialization in stem cell deficiency and corneal injuries has become reality in clinical setting. Mediators and course of events during stromal healing have been detailed, and new treatment regimens including gene (decorin) and stem cell therapy for excessive healing have been designed. This is a very important advance given the popularity of various refractive surgeries entailing stromal wound healing. Successful surgical ways of replacing the diseased endothelium have been clinically tested, and new approaches to accelerate endothelial healing and suppress endothelial-mesenchymal transformation have been proposed including Rho kinase (ROCK) inhibitor eye drops and gene therapy to activate TGF-β inhibitor SMAD7.

    2012-04-01

    Care of equine wounds in the field can be a challenging endeavor. Many times, wound care is complicated by chronicity or by prior inappropriate care in addition to the great degree of tissue trauma that occurred when the horse was wounded. Recognizing involvement of synovial structures, loss of skin, and damage to bone are critical in the initial examination of wounds and will guide future care. Education of clients is also important in that preparing them for possible outcomes during healing may help improve compliance and proper treatment of wound. Owners and trainers often perform much of the daily care and monitoring of equine wounds and thus can greatly assist or impede the progress. Bandaging is important to management of equine wounds-especially on the limbs-and is sometimes overlooked because of its labor-intensive nature and the desire for a spray, ointment, or salve that will heal the wound. The practitioner that improves and utilizes his or her understanding of the wound-healing process in concert with his or her knowledge of local anatomy will be the one who is best equipped to care for wounds in ambulatory practice.

    2016-11-01

    Full Text Available This paper details the study of biodynamic excisional skin tension lines on the scalp, and the development of a new flap technique for closure of scalp wounds. Recently, a study by this author, on pigskin, replicated whorls by placing tissue under rapid stretch using saline tissue expanders, by re-creating rapid dermo-epidermal shear of skin – thereby concluding that the golden spiral pattern is nature’s own pattern for rapid expansion. Given the relationship between tissue expansion and stretch have been shown to cause deformation gradients that have both elastic and growth factors, the author set out to test the hypothesis that a golden spiral pattern therefore would be more efficient at closing wounds under less tension when compared to standard semicircular rotational flap patterns. The author conducted a series of experiments, both on pigskin (to first confirm the hypothesis, using a recently developed computerized tensiometer and later a clinical study. This paper presents a new random pivotal flap technique for skin closures on the head and neck: The Golden Spiral Flap. Biomechanics, planning and advantages of this new flap are described in this paper.

    This study aimed to establish the prevalence and aetiology of wounds, allowing an insight into the management of wound care, the use of dressings and the nursing time allocated to the provision of wound care in a community setting in Ireland. A cross-sectional survey was used, with data collected on all clients in the community who received treatment from public health nurses or community registered general nurses for wound care over a 1-week period in April 2013. A 98.9% response rate was realised, and 188 people were identified as having wounds, equating to a crude prevalence of 5% of the active community nursing caseload. A total of 60% (n=112) had leg ulcers, 22% (n=42) had pressure ulcers, 16% (n=30) had an acute wound (surgical or traumatic wounds), 1% (n=2) had a diabetic foot wound and a further 1% (n=2) had wounds of other aetiologies. The mean duration of wounds was 5.41 months. A total of 18% of wounds were identified as infected; however, 60% (n=112) of wounds had antimicrobial products in use as either a primary or secondary dressing. The study established that there is a significant prevalence of wounds in this community care area. There was absence of a clinical diagnosis in many cases, and evidence of inappropriate dressing use, risking an increase in costs and a decrease in good clinical outcomes. It also highlighted the importance of ongoing education and auditing in the provision of wound care.

    Wound healing in ischemic tissues such as flap margins due to inadequate blood supply is still a source of considerable morbidity in surgical practice. Adequate tissue perfusion is particularly important in wound healing. We investigated the effects of recombinant human erythropoietin (rHuEPO) on wound healing in an ischemic skin wound model. Sixty-three Sprague-Dawley rats were used. Normal incisional wound and H-shaped double flaps were used as the wound models. Animals were treated with rHuEPO (400 IU/kg) or its vehicle. Rats were killed on different days (3, 5, and 10 days after skin injury) and the wounded skin tissues were used for immunohistochemistry and for analysis of vascular endothelial growth factor content and collagen content. Tissue transglutaminase immunostaining of histological specimens was used as a vascular marker to determine the level of microvessel density. The results showed a higher level of vascular endothelial growth factor protein and an increased microvessel density in ischemic wounds with rHuEPO treatment than the normal incisional wounds and ischemic control wounds. Collagen content was higher in the incisional wounds and in the ischemic wounds with rHuEPO treatment compared with the ischemic control wounds. Our results suggest that erythropoietin may be an effective therapeutic approach in improving healing in ischemic skin wounds.

    Full Text Available PURPOSE: To investigate the effects of topical application of an Aloe vera gel combined or not with microcurrent application on the healing of skin wounds surgically induced in Wistar rats. METHODS: The animals were randomly divided into the following groups: control group, animals topically treated with Aloe vera, animals treated with a microcurrent, and animals receiving topical application of Aloe vera combined with microcurrent application. RESULTS: The results indicated differences in wound healing between the various treatments when compared to the control group. Tissue hyperplasia was lower in the control group compared to the other treated groups. Accelerated wound healing was observed in the group treated with Aloe vera compared to control. Animals submitted to microcurrent application only and the group treated with microcurrent plus Aloe vera presented an earlier onset of the proliferative phase compared to the control group and animals treated with Aloe vera gel alone. Morphometric data confirmed the structural findings. CONCLUSION: Simultaneous application of Aloe vera gel and microcurrent is an excellent choice for the treatment of open wounds thus indicating a synergistic action of these two applications.OBJETIVO: Investigar os efeitos da aplicação tópica do gel de Aloe vera, combinada ou não com a aplicação de microcorrente no reparo de lesões cutâneas induzidas cirurgicamente em ratos Wistar.

    Wound healing, as a normal biological process in the human body, is achieved through four precisely and highly programmed phases: hemostasis, inflammation, proliferation, and remodeling. For a wound to heal successfully, all four phases must occur in the proper sequence and time frame. Many factors can interfere with one or more phases of this process, thus causing improper or impaired wound healing. This article reviews the recent literature on the most significant factors that affect cutaneous wound healing and the potential cellular and/or molecular mechanisms involved. The factors discussed include oxygenation, infection, age and sex hormones, stress, diabetes, obesity, medications, alcoholism, smoking, and nutrition. A better understanding of the influence of these factors on repair may lead to therapeutics that improve wound healing and resolve impaired wounds. PMID:20139336

    Diabetes Mellitus Type II (DM2) is a growing international health concern with no end in sight. Complications of DM2 involve a myriad of comorbidities including the serious complications of poor wound healing, chronic ulceration, and resultant limb amputation. In skin wound healing, which has definite, orderly phases, diabetes leads to improper function at all stages. While the etiology of chronic, non-healing diabetic wounds is multi-faceted, the progression to a non-healing phenotype is closely linked to poor vascular networks. This review focuses on diabetic wound healing, paying special attention to the aberrations that have been described in the proliferative, remodeling, and maturation phases of wound angiogenesis. Additionally, this review considers therapeutics that may offer promise to better wound healing outcomes. PMID:28671607

    Wounds are a serious healthcare issue with profound personal, clinical and economic implications. Using a working definition of compromised wounds, this study examines the prevalence of wounds by type and by healthcare setting using data from hospitals, home care, hospital-based continuing care and long-term care facilities within fiscal year 2011-2012 in Canada. It also evaluates several risk factors associated with wounds, such as diabetes, circulatory disease and age. Compromised wounds were reported in almost 4% of in-patient acute hospitalizations and in more than 7% of home care clients, almost 10% of long-term care clients and almost 30% of hospital-based continuing care clients. Patients with diabetes were much more likely to have a compromised wound than were patients without the disease. Copyright © 2014 Longwoods Publishing.

    Open wounds of the distal third of the leg and foot with exposed bone, fractures, and hardware are challenging wounds for which to achieve stable coverage. The orthopedic advances in lower extremity fracture management over the last 30 years have allowed a rethinking of the standard operative approach to close these complex wounds. The ability of extracellular matrix (ECM) products to facilitate constructive remodeling of a wound seemed a reasonable approach for treatment, especially in patients who are often poor surgical candidates for more advanced reconstructive procedures. The authors reviewed 9 patients with 11 open fractures of the leg, ankle, or foot treated with a newer ECM wound healing device to total closure. The clinical course and patient management are reviewed. The authors conclude that newer ECM products can provide a reasonable method of management for patients who have wounds with exposed hardware, distal leg wounds, and open foot fractures compared to prolonged negative pressure wound therapy or complex reconstructive operative procedures.

    A structured approach to wound assessment is required to maintain a good standard of care. This involves a thorough patient assessment, which should be carried out by skilled and competent practitioners, adhering to local and national guidelines (Harding et al, 2008). Inappropriate or inaccurate assessment can lead to delayed wound healing, pain, increased risk of infection, inappropriate use of wound dressings and a reduction in the quality of life for patients.

    Full Text Available Verificou-se o grau de isquemia produzido pela tração dos afastadores, bem como determinou-se o índice de infecção nas feridas limpas e contaminadas quando submetidas a trações conhecidas e progressivas. Foram utilizados 104 ratos machos da cepa Wistar com peso entre 180 e 190 gr, sendo que 40 animais foram utilizados para a determinação da isquemia provocada por afastadores e 64 para estudo da correlação do emprego de afastadores com infecção. Para a análise da isquemia produzida por afastadores sobre a ferida cirúrgica, os 40 ratos foram divididos em 4 grupos: T0, T1, T2, T3. Para o estudo do risco de infecção produzido por afastadores sobre a ferida cirúrgica, 64 ratos foram divididos em oito grupos: C0, C1, C2, C3, L0, L1, L2 e L3. Todos animais foram submetidos a laparotomia paramediana, conservando-se íntegro o peritônio. A ferida foi então submetida a tração por afastadores.

    Innovation in medicine requires unique partnerships between academic research, biotech or pharmaceutical companies, and health-care providers. While innovation in medicine has greatly increased over the past 100 years, innovation in wound care has been slow, despite the fact that chronic wounds are a global health challenge where there is a need for technical, process and social innovation. While novel partnerships between research and the health-care system have been created, we still have much to learn about wound care and the wound-healing processes.

    Non-healing chronic wounds present a major biological, psychological, social, and financial burden on both individual patients and the broader health system. Pathologically extensive inflammation plays a major role in the disruption of the normal healing cascade. The causes of chronic wounds (venous, arterial, pressure, and diabetic ulcers) can be examined through a juxtaposition of normal healing and the rogue inflammatory response created by the common components within chronic wounds (ageing, hypoxia, ischaemia-reperfusion injury, and bacterial colonisation). Wound bed care through debridement, dressings, and antibiotics currently form the basic mode of treatment. Despite recent setbacks, pharmaceutical adjuncts form an interesting area of research.

    Oral wounds heal faster and with less scar formation than skin wounds. One of the key factors involved is saliva, which promotes wound healing in several ways. Saliva creates a humid environment, thus improving the survival and functioning of inflammatory cells that are crucial for wound healing. In addition, saliva contains several proteins which play a role in the different stages of wound healing. Saliva contains substantial amounts of tissue factor, which dramatically accelerates blood clotting. Subsequently, epidermal growth factor in saliva promotes the proliferation of epithelial cells. Secretory leucocyte protease inhibitor inhibits the tissue-degrading activity of enzymes like elastase and trypsin. Absence of this protease inhibitor delays oral wound healing. Salivary histatins in vitro promote wound closure by enhancing cell spreading and cell migration, but do not stimulate cell proliferation. A synthetic cyclic variant of histatin exhibits a 1,000-fold higher activity than linear histatin, which makes this cyclic variant a promising agent for the development of a new wound healing medication. Conclusively, recognition of the many roles salivary proteins play in wound healing makes saliva a promising source for the development of new drugs involved in tissue regeneration.

    Infection remains the most common and significant complication after high-energy fractures. The Bioburden Study is a multicenter, prospective, observational cohort study of wound bacterial bioburden and antibiotic care in severe open lower extremity fractures. The aims of this study are to (1) characterize the contemporary extremity wound "bioburden" at the time of definitive wound closure; (2) determine the concordance between polymerase chain reaction results and hospital microbiology; (3) determine, among those who develop deep infections, the concordance between the pathogens at wound closure and at deep infection; and (4) compare the probability of deep infection between those who did and did not receive an appropriate course of antibiotics based on bioburden at the time of wound closure. To address these aims, sites collected tissue samples from severe lower extremity injuries at the time of wound closure and at first surgery for treatment of a deep infection, nonunion, flap failure, amputation, or other complications (because these surgeries may be due to undetected infection). Otherwise, if no further surgical treatment occurred, participants were followed for 12 months. The study was conducted at 38 US trauma centers and has enrolled 655 participants aged 18-64 years. This is the first large multi-institutional study evaluating the wound bioburden of severe open tibia fractures and correlating this bioburden with the risk of wound complications after definitive soft tissue closure.

    The First World War was a huge tragedy for mankind, but, paradoxically, it represented a source of significant progress in a broad series of human activities, including medicine, since it forced physicians to improve their knowledge in the treatment of a large number of wounded soldiers. The use of heavy artillery and machine guns, as well as chemical warfare, caused very serious and life-threatening lesions and wounds. The most frequent causes of death were not mainly related to gunshot wounds, but rather to fractures, tetanus and septic complications of infectious diseases. In the first part of this article, we describe the surgical procedures and medical therapies carried out by Italian physicians during the First World War, with the aim of treating wounded soldiers in this pre-antibiotic era. Antibacterial solutions, such as those of Dakin-Carrel and sodium hypochlorite and boric acid, the tincture of iodine as well as the surgical and dressing approaches and techniques used to remove pus from wounds, such as ignipuncture and thermocautery or lamellar drainage are reported in detail. In the second part of the paper, the organization of the Italian military hospitals network, the systems and tools useful to transport wounded soldiers both in the front lines and in the rear is amply discussed. In addition, the number of soldiers enrolling, and those dying, wounded or missing during the Great War on the Italian front is estimated.

    Irregularly shaped wounds or flap borders usually require specified software or devices to measure their area and follow-up wound healing. In this study, an easy way of area measurement called histogram planimetry (HP) for wounds with irregular geometric shapes is defined and compared to conventional millimetric wound measurement. Ten irregularly bordered geometric shapes were measured by 4 different individuals working as surgical assistants using both HP and manual millimetric measurement tools. The amount of time for each wound shape calculation as well as the measurements of the wound areas were noted. All measurements were compared for each method and between each individual using the Wilcoxon signed-rank test. There was no statistically significant difference between 2 measurement methods by means of measured areas; however, measurement time was significantly lower when the HP method was used. There also was no significant difference between the individuals' measurements and calculation times. These results indicated that HP is useful as a conventional millimetric square wound measurement technique with significantly lower measurement times. Due to the development of photo-editor software technologies, measurements in the surgical field have become more accurate and rapid than conventional manual methods without consuming the time and energy needed for other studies. A future study including comparisons between the presented method and complex computerized measurement methods, in terms of duration and accuracy, may provide additional supportive data for the authors' method.

  4. Understanding methods of wound debridement.

    Science.gov (United States)

    Atkin, Leanne

    Autolytic debridement describes the body's natural method of wound-bed cleansing, helping it to prepare the wound bed for healing. In acute wounds, autolytic debridement occurs automatically and often does not require intervention, as during the inflammatory stage of a wound, neutrophils and macrophages digest and removes devitalised tissue, cell debris and contaminants, clearing the wound of any cellular barriers to healing. In chronic wounds, by contrast, healing is often delayed, frequently because of inadequate debridement. The autolytic process becomes overwhelmed by high levels of endotoxins released from damaged tissue (Broadus, 2013). Therefore wound debridement becomes an integral part of chronic-wound management and practitioners involved in wound care must be fully competent at wound-bed assessment and have an awareness of the options available for debridement. This article will review wound-bed assessment, highlighting variations in devitalised tissue, and explore options available for wound debridement, taking into consideration patients’ pain and quality of life.

    Psychological stress has been shown to delay wound healing. Several trials have investigated whether psychological interventions can improve wound healing, but to date, this evidence base has not been systematically synthesized. The objective was to conduct a systematic review of randomized controlled trials in humans investigating whether psychological interventions can enhance wound healing. A systematic review was performed using PsychINFO, CINAHL, Web of Science, and MEDLINE. The searches included all papers published in English up until September 2016. The reference lists of relevant papers were screened manually to identify further review articles or relevant studies. Nineteen studies met inclusion criteria and were included in the review. Fifteen of nineteen studies were of high methodological quality. Six studies were conducted with acute experimentally created wounds, five studies with surgical patients, two studies with burn wounds, two studies with fracture wounds, and four studies were conducted with ulcer wounds. Post-intervention standardized mean differences (SMD) between groups across all intervention types ranged from 0.13 to 3.21, favouring improved healing, particularly for surgical patients and for relaxation interventions. However, there was some evidence for publication bias suggesting negative studies may not have been reported. Due to the heterogeneity of wound types, population types, and intervention types, it is difficult to pool effect sizes across studies. Current evidence suggests that psychological interventions may aid wound healing. Although promising, more research is needed to assess the efficacy of each intervention on different wound types. Statement of contribution What is already known on this subject? Psychological stress negatively affects wound healing. A number of studies have investigated whether psychological interventions can improve healing. However, no systematic reviews have been conducted. What does this study add

    Mechanical forces greatly influence cellular organization and behavior. Cells respond to applied stress by changes in form and composition until a suitable state is reestablished. However, without any mechanical stimuli cells stop proliferating, discontinue migration, go into cell-cycle arrest, and eventually die. Hence, one can assume that pathologies closely depending on cell migration like cancer or atherosclerosis might be governed by biophysical parameters. Moreover, mechanical cues will have fundamental effects in wound healing. Especially negative pressure wound therapy has the potential to endorse wound healing by induction of both macrodeformation (wound contraction) and microdeformation (tissue reactions at microscopic level). So far, the capacity for researchers to study the link between mechanical stimulation and biological response has been limited by the lack of instrumentation capable of stimulating the tissue in an appropriate manner. However, first reports on application of micromechanical forces to wounds elucidate the roles of cell stretch, substrate stiffness, and tissue deformation during cell proliferation and differentiation. This review deals with their findings and tries to establish a link between the current knowledge and the questions that are essential to clinicians in the field: What is the significance of mirodeformations for wound healing? Does "dead space" impede propagation of mechanical cues? How can microdeformations induce cell proliferation? What role do fibroblasts, myofibroblasts, and mesenchymal stem cells play in chronic wounds with regard to micromechanical forces? © 2013 by the Wound Healing Society.

Abdominal fascial closure is an area of considerable variation within the field of general surgery. The formation of hernias following abdominal wall incisions continues to be a challenging problem. Ventral hernia repairs are among the most common surgeries performed by general surgeons, and despite many technical advances in the field, incisional hernia rates remain high. Much attention and research has been directed to the surgical management of hernias. Less focus has been placed on prevention of hernia formation despite its obvious importance. This review examines the effects of factors such as the type of incision, suture type and size, closure method, patient risk factors, and the use of prophylactic mesh.

    Effective wound bed preparation is an essential element in the healing of chronic wounds, including pressure ulcers (PUs). Negative pressure wound therapy (NPWT) reduces oedema, stimulates the formation of granulation tissue and helps remove wound exudate. This helps prepare the wound bed for secondary healing, skin grafting or coverage with flaps. Combining NPWT with an instillation phase using an antiseptic (octenidine based) irrigation solution is a novel approach to PU management. Three patients with Category 4 gluteal PUs were treated with NPWT and instillation fluid, following surgical debridement of necrotic tissue. The aim was to achieve optimal wound bed preparation prior to wound closure by local fasciocutaneous flap. The antiseptic efficacy of octenilin wound irrigation solution in microorganism eradication was quantified by in vitro tests simulating real conditions using leg ulcer vacuum exudates.

This is especially true in the postmenopausal state, where lipid profiles and CHD risk mimic that of age-matched men. Thus, interventions designed to reduce CHD risk by raising HDL-C levels may have particular significance during the transition to menopause. This review discusses HDL-C-raising therapies and the role of HDL in the primary prevention of CHD in women. Lifestyle-based interventions such as dietary change, aerobic exercise regimens, and smoking cessation are initial steps that are effective in raising HDL-C, and available data suggest women respond similarly to men with these interventions. When combined with pharmacotherapy, the effects of these lifestyle alterations are further amplified. Though studies demonstrating gender-specific differences in therapy are limited, niacin continues to be the most effective agent in raising HDL-C levels, especially when used in combination with fibrate or statin therapy. Emerging treatments such as HDL mimetic therapy show much promise in further raising HDL-C levels and improving cardiovascular outcomes.Keywords: high-density lipoprotein, HDL, women, cholesterol, heart disease

    Full Text Available This study was performed to investigate the different methods of treating hyper granulation tissue on experimentally induced wounds in equine limbs. Wounds were induced by removal of a skin patch and subcutaneous tissue for about 5-7 cm width and 6-8 cm in length from the dorsal and lateral aspect of the fore and hind limbs below the carpal and tarsal joints. The wounds were left open without treatment and the animals were trained 2-2.5 hours every day for about 3-5 weeks until hyper granulation tissue was developed. The schedule for the treatment of hyper granulation was divided into five groups each contained eight wounds of hyper granulation tissue; each main group was divided into two subgroups. The subgroups of first, second, third, fourth and fifth groups were treated by the following schedules: bandage alone; copper sulphate ointment 10%; silver nitrate ointment 2%; red mercury ointment 11%; and laser therapy (at a total dose of 9.72 Joule / cm2 respectively. While the second subgroups were treated by surgical resection of the hyper granulation tissue, followed by the same treatments applied on the first subgroup. The bandage for all experimental groups was changed every 48 hours until healing was occurred. The clinical and histological observation of the first group revealed that the healing take long period comparing with other groups. The mean of wound healing were 65 days in non surgical removal of hyper granulation tissue subgroup, while 57 days in surgical removed of hyper granulation tissue subgroup. The results of the second, third, fourth groups revealed that the caustic material especially red mercury has a role in healing processes through depressing the hyper granulation tissue. The mean of wound healing of the second group was 42.25 days in non surgical removal of hyper granulation tissue subgroup while 37.25 days in surgically removed hyper granulation tissue subgroup. In the third group the mean of wound healing was 45

    regulatory and reimbursement bodies in various countries regarding both study design and the ways in which results are interpreted. In response to this confusion, the European Wound Management Association (EWMA) has been publishing a number of interdisciplinary documents(15-19) with the intention of highlighting: The nature and extent of the problem for wound management: from the clinical perspective as well as that of care givers and the patients Evidence-based practice as an integration of clinical expertise with the best available clinical evidence from systematic research The nature and extent of the problem for wound management: from the policy maker and healthcare system perspectives The controversy regarding the value of various approaches to wound management and care is illustrated by the case of NPWT, synonymous with topical negative pressure or vacuum therapy and cited as branded VAC (vacuum-assisted closure) therapy. This is a mode of therapy used to encourage wound healing. It is used as a primary treatment of chronic wounds, in complex acute wounds and as an adjunct for temporary closure and wound bed preparation preceding surgical procedures such as skin grafts and flap surgery. Aim An increasing number of papers on the effect of NPWT are being published. However, due to the low evidence level the treatment remains controversial from the policy maker and health-care system's points of view-particularly with regard to evidence-based medicine. In response EWMA has established an interdisciplinary working group to describe the present knowledge with regard to NPWT and provide overview of its implications for organisation of care, documentation, communication, patient safety, and health economic aspects. These goals will be achieved by the following: Present the rational and scientific support for each delivered statement Uncover controversies and issues related to the use of NPWT in wound management Implications of implementing NPWT as a treatment strategy in the

    de a ferida estar completamente fechada e sem crostas, a pele desses animais estava espessada e na derme do grupo T2 parecia ter fibrose mais acentuada do que nos outros grupos. Esses resultados demonstraram que o tratamento tópico com óleo de C. langsdorffii prejudicou o processo de reparação normal de ferida na presença de corpo estranho.Copaifera langsdorffii is a Brazilian native leguminosae that produce resin-oil, popularly known as copaíba oil. This oil is used for the treatment of skin wound due to its recognized antiinflammatory and wound healing effects. Despite, its popular use, there are few published data about the therapeutic effect of this medicinal plant. The aim of the study was to evaluate the topic treatment effect of the Copaíba oil on the process of skin repair inflammation induced by a foreign body subcutanously implanted. Sixty BALB/c mice were submitted to a 1cm linear incision and a 12mm circle coverslip was subcutaneously implanted. Four treatments groups were established: control, sterile saline (C; vehicle control, sterile mineral oil, (VC; treatment 1 (T1, mineral oil plus copaiba oil (V/V, and treatment 2 (T2 copaiba oil. The evaluations were performed at pre-determined time points (1, 3, 5, 7 and 14 days. It was possible to find fibroblasts, epithelial cells proliferation, re-epithelization and newly formed blood vessels in all groups, however, all oil treated groups (T1 and T2 did not present re-epithelization at three days post surgical incision. On days 5 and 7, a higher intensity of edema and hyperemia on the groups T1 and T2 was observed, besides that, the T1 and T2 groups presented a serous cellular scab on the wounds that was absent on the C and VC groups. The inflammatory reactions among the groups C and VC showed more mononuclear cells than the T1 and T2 groups that presented a mixed cell patter composed from both mono and polymorphonuclear cells. Although the surgical wounds were re-epithelizaded, in the groups T1 and T2

    In recent years, a new technology for autologous epidermal harvesting has been developed to produce epidermal skin grafts (ESGs) for use over wounds. This technology employs negative pressure and heat to raise the epidermal skin layer, allowing for consistent and reproducible epidermal harvesting. The aim of this case series is to present the authors' experience using an automated, epidermal harvesting system to produce ESGs to treat wounds of patients with multiple comorbidities. This case series was conducted between January 1, 2013 and December 31, 2014. Patients with wounds (≤ 25 cm2) that failed to heal were treated with ESGs by a group of 3 wound care physicians in 2 outpatient wound care centers in a community health center setting. A total of 94 patients with 102 wounds were identified. Of the 94 patients, 3 were noncompliant and 9 were lost to follow-up. Therefore, 82 patients with 90 wounds were included in the analysis. The majority of wounds demonstrated epithelialization (83/90, 92.2%). Of the 90 wounds, 75 (83.3%) healed following epidermal grafting, 4 (4.4%) wounds displayed improvement, and 11 (12.2%) did not heal. Minimal or no pain at the donor site was reported by the patients, and all donor sites healed without complications. This case series provides additional evidence for the use of ESGs for the treatment of wounds that fail to heal.

    1985-01-01

    In a prospective study, 31 patients with brown recluse spider bites were treated by either immediate surgical excision or with the leukocyte inhibitor, dapsone, followed by delayed surgical excision. Patients were matched for age, gender, and lesion size and were excluded if the typical history and physical findings were not present. In patients treated with immediate surgical excision (N = 14), delayed wound healing (N = 5) and objectional scarring (N = 7) were common complications. However, pretreatment treatment with dapsone reduced the incidence of wound complications (N = 1) and objectional scarring (N = 1) (p less than 0.05), while reducing the need for surgical excision (N = 1). There were no severe drug reactions due to dapsone, although one patient had persistent G.I. upset. Pretreatment with dapsone not only reduced surgical complications but also improved the outcome of patients bitten by the brown recluse spider. PMID:4051613

    Multiple risk factors for orthopaedic surgical site infection have been identified. Some of these factors directly affect the wound-healing process, whereas others can lead to blood-borne sepsis or relative immunosuppression. Modifying a patient's medications; screening for comorbidities, such as HIV or diabetes mellitus; and advising the patient on options to diminish or eliminate adverse behaviors, such as smoking, should lower the risk for surgical site infections.

    Treatment of combat injuries and resulting wounds can be difficult to treat due to compromised and evolving tissue necrosis, environmental contaminants, multidrug resistant microbacterial and/or fungal infections, coupled with microvascular damage and/or hypovascularized exposed vital structures. Our group has developed surgical care algorithms with identifiable salvage techniques to achieve stable, definitive wound coverage often with the aid of certain regenerative medicine biologic scaffold materials and advanced wound care to facilitate tissue coverage and healing. This case series reports on the role of urinary bladder matrix scaffolds in the wound care and reconstruction of traumatic and combat wounds. Urinary bladder matrix was found to facilitate definitive soft tissue reconstruction by establishing a neovascularized soft tissue base acceptable for second stage wound and skin coverage options within traumatic and combat-related wounds.

  6. Tobacco smoking and surgical healing of oral tissues: A review

    Full Text Available It is believed that the crew of Columbus had introduced tobacco from the ′American India′ to the rest of the world, and tobacco was attributed as a medicinal plant. It was often used to avert hunger during long hours of work. But in reality, tobacco causes various ill effects including pre-malignant lesions and cancers. This article aims at reviewing the literature pertaining to the effect of tobacco smoking upon the outcome of various surgical procedures performed in the oral cavity. Tobacco affects postoperative wound healing following surgical and nonsurgical tooth extractions, routine maxillofacial surgeries, implants, and periodontal therapies. In an experimental study, bone regeneration after distraction osteogenesis was found to be negatively affected by smoking. Thus, tobacco, a peripheral vasoconstrictor, along with its products like nicotine increases platelet adhesiveness, raises the risk of microvascular occlusion, and causes tissue ischemia. Smoking tobacco is also associated with catecholamines release resulting in vasoconstriction and decreased tissue perfusion. Smoking is believed to suppress the innate and host immune responses, affecting the function of neutrophils - the prime line of defense against infection. Thus, the association between smoking and delayed healing of oral tissues following surgeries is evident. Dental surgeons should stress on the ill effects of tobacco upon the routine postoperative healing to smoker patients and should aid them to become tobacco-free.

    Full Text Available Embora os fios de sutura empregados rotineiramente em cirurgias bucais possam favorecer o acúmulo e o crescimento bacteriano, há poucos trabalhos na literatura relatando preocupação com a anti-sepsia da ferida cirúrgica durante o período pós-operatório e antes de sua remoção. O presente trabalho teve por objetivo avaliar o efeito de dois métodos de anti-sepsia intra-oral sobre o crescimento bacteriano em fios de sutura de algodão. Os resultados evidenciaram que todos os fios de sutura apresentaram-se contaminados com estreptococos, antes e após a anti-sepsia da ferida cirúrgica. A análise dos resultados obtidos permitiu concluir que os dois métodos de anti-sepsia avaliados reduziram o número de estreptococos isolados dos fragmentos de fios de sutura, entretanto, a análise estatística demonstrou que os dois métodos avaliados não apresentaram diferenças estatisticamente significantes.The objective of this study was to evaluate bacterial growth on cotton suture. The efficiency of cetylpyridinium chloride (50%, hydrogen peroxide (3% and chlorhexidine (0.12% in antisepsis was investigated. For that, 20 patients who were submitted to extraction of impacted lower third molars were studied. Five days after extraction, samples were obtained from the oral and alveolar sides of the sutures, before and after antisepsis of the wounds, and were submitted to bacteriological analysis. Bacterial growth was observed in all examined samples. The number of streptococci decreased after antisepsis and there were no statistically significant differences between the methods of antisepsis used.

    Mucormycosis is the most acute, fulminate, and fatal of all fungal infections in humans. It presents most frequently in immunocompromised patients, but can occur in healthy patients in the presence of often-insignificant trauma. Surgical management of primary cutaneous mucormycosis is almost always required. Case reports of surgical treatment for primary cutaneous mucormycosis are reported in the literature; however, the extent of debridement required for cure is unclear and no uniform plan of treatment has been suggested. To date, no clinical guidelines exist to assist the clinician in the surgical management of this disease. This article reviews the literature, reports on two clinical cases, and submits clinical guidelines designed to assist the clinician in the surgical management of primary cutaneous mucormycosis. Because of the infrequent and potentially fatal nature of the diagnosis, a high index of suspicion and a low threshold for wound biopsy must be maintained. Wound cultures are grossly inadequate and should not be relied on for a false sense of security. It is recommended that, for the early diagnosis of cutaneous mucormycosis, chemotherapy and surgical debridement of grossly necrotic tissue be performed at the earliest possible time. The debrided wound is monitored for the resolution of surrounding erythema and induration before definitive reconstruction. In the case of delayed diagnosis and/or advanced or rapidly progressive disease, surgical debridement of all involved tissue, in addition to chemotherapy, is warranted.

    A hand injury occurred at a U.S. facility in 1985 involving a pointed shaft (similar to a meat thermometer) that a worker was using to remove scrap solid plutonium from a plastic bottle. The worker punctured his right index finger on the palm side at the metacarpal-phalangeal joint. The wound was not through-and- through, although it was deep. The puncture wound resulted in deposition of ~48 kBq of alpha activity from the weapons-grade plutonium mixture with a nominal 12 to 1 Pu-alpha to {sup 241}Am-alpha ratio. This case clearly showed that DTPA was very effective for decorporation of plutonium and americium. The case is a model for management of wounds contaminated with transuranics: (1) a team approach for dealing with all of the issues surrounding the incident, including the psychological, (2) early surgical intervention for foreign-body removal, (3) wound irrigation with DTPA solution, and (4) early and prolonged DTPA administration based upon bioassay and in vivo dosimetry.

    To determine and model the relationships between phacoemulsification conditions and viscoelastic agents that result in thermal wound injury. Animal laboratory, Irvine, California, USA. Mechanical and animal models, various wound sizes, phacoemulsification tips, and dispersive and cohesive viscoelastic agents were evaluated. Settings for phaco power, vacuum, and irrigation levels were controlled within a surgically relevant range. In the mechanical and animal models, incision temperature was assessed as a function of phacoemulsification parameters and time. In the animal model, wound damage was evaluated at the time of surgery. Induced time delays from the onset of phaco power to the onset of irrigation flow caused a thermal rise at the incision site. In these experiments, lack of irrigation and aspiration resulted in the greatest thermal rise and caused wound damage. Both the cohesive and dispersive viscoelastic agents were associated with a delay in the start of irrigation and aspiration, which resulted in similar maximum temperatures. Mathematical models were developed to estimate the maximum incision temperature from the phacoemulsification power, the duration (seconds) of occlusion, the tip gauge and type, and other phacoemulsification parameters. The models predict that under comparable conditions, occlusion with a viscoelastic agent will result in higher incision temperatures than occlusion with a balanced salt solution. Under comparable phacoemulsification conditions, both the cohesive and dispersive viscoelastic agents were associated with elevated temperatures that would be preventable by ensuring irrigation and aspiration flow before the onset of phacoemulsification power.

  17. Fibronectin and wound healing.

    Science.gov (United States)

    Grinnell, F

    1984-01-01

    I have tried to briefly review the evidence (summarized in Table II) indicating that fibronectin is important in cutaneous wound healing. Fibronectin appears to be an important factor throughout this process. It promotes the spreading of platelets at the site of injury, the adhesion and migration of neutrophils, monocytes, fibroblasts, and endothelial cells into the wound region, and the migration of epidermal cells through the granulation tissue. At the level of matrix synthesis, fibronectin appears to be involved both in the organization of the granulation tissue and basement membrane. In terms of tissue remodeling, fibronectin functions as a nonimmune opsonin for phagocytosis of debris by fibroblasts, keratinocytes, and under some circumstances, macrophages. Fibronectin also enhances the phagocytosis of immune-opsonized particles by monocytes, but whether this includes phagocytosis of bacteria remains to be determined. In general, phagocytosis of bacteria has not appeared to involve fibronectin. On the contrary, the presence of fibronectin in the wound bed may promote bacterial attachment and infection. Because of the ease of experimental manipulations, wound healing experiments have been carried out on skin more frequently than other tissues. As a result, the possible role of fibronectin has not been investigated thoroughly in the repair of internal organs and tissues. Nevertheless, it seems reasonable to speculate that fibronectin plays a central role in all wound healing situations. Finally, the wound healing problems of patients with severe factor XIII deficiencies may occur because of their inability to incorporate fibronectin into blood clots.

    Arginine metabolism in wounds was investigated in the rat in 1) lambda-carrageenan-wounded skeletal muscle, 2) Schilling chambers, and 3) subcutaneous polyvinyl alcohol sponges. All showed decreased arginine and elevated ornithine contents and high arginase activity. Arginase could be brought to the wound by macrophages, which were found to contain arginase activity. However, arginase was expressed by macrophages only after cell lysis and no arginase was released by viable macrophages in vitro. Thus the extracellular arginase of wounds may derive from dead macrophages within the injured tissue. Wound and peritoneal macrophages exhibited arginase deiminase activity as demonstrated by the conversion of (guanido-/sup 14/C)arginine to radiolabeled citrulline during culture, the inhibition of this reaction by formamidinium acetate, and the lack of prokaryotic contamination of the cultures. These findings and the known metabolic fates of the products of arginase and arginine deiminase in the cellular populations of the wound suggest the possibility of cooperativity among cells for the production of substrates for collagen synthesis.

    2014-07-01

    Post-sternotomy mediastinitis is the most severe surgical site infection after sternotomy with an incidence between 1-4% related to the patient co-morbidity. This complication will increase morbidity and mortality and may also have an economic impact. There are guidelines to prevent surgical site infections; however, age and co-morbidities increase and therefore it is important to develop new tools to improve wound healing. This manuscript will give an overview of a new concept using negative pressure wound therapy over a closed incision (so-called, closed incision management) after surgery and will include the principles of negative pressure wound therapy and the positively applied mechanical forces as a permutation of Wolff's law. The use and indication of this therapy is supported by experimental studies divided into physiological and biomechanical property studies. Finally, an overview of clinical studies is given based on the evidence rating scale for therapeutic studies.

    2002-01-01

    The prominent tenets of limb's wound surgery have been improved during the Great War. Before 1914, traditional treatment of war injuries was usually applied on the ground because injuries caused by firearms were supposedly trivial while the threatening infection refrained surgeons from acting. From the very start of 1914, gangrene and septicaemia were the terrible consequences of new types of injuries provoked by shrapnel, all the more dangerous that the wounded men were numerous and the injuries were nursed after a too important delay. New surgical facilities have been organised by the French Military Health Service which created the "Ambulances Chirurgicales Automobiles", improved the selection procedures and the mobilization of many surgeons. New surgical treatments such as lancing, continuous use irrigation, delayed suture of wounds allowed improvement of results and saved more than one soldier. Finally, the excision of dead and contaminated tissues is still nowadays the most important progress in war surgery.

  1. The modern concept of wound healing in glaucoma surgery

    S. Yu. Petrov

    2015-01-01

    Full Text Available Post-operative wound healing is one of the key-factors, defining success of filtrating surgery in late post-operative period. Wound healing is a physiological response directed at tissue structure reconstruction and function restoration, performed by several interacting cellular pathways. Surgical trauma leads to plasma proteins penetration to the filtration zone, as well as coagulation pathway and complement activation. The process of wound healing can be divided into three interconnected stages: inflammation, proliferation and scar remodeling. Inflammation is a protective response to tissue damage, that helps preserve its structure and cellular functions. It is characterized by neutrophil and monocyte arrival at the wound site. Neutrophils phagocytose the wound infecting bacteria and clean the wound site. Macrofages aid wound cleansing, participate in phagocytosis and produce a range of factors, necessary for new tissue formation. Proliferation stage consists of reepithelization and granulation tissue formation, which is accompanied by growth factors release. The growth factors stimulate the extracellular matrix formation and fibroblast proliferation. The last stage of the wound healing process is characterized by extracellular matrix remodeling with wound debridement achieved by a simultaneous synthesis and destruction of certain matrix components, cell differentiation, maturation and apoptosis. Apoptosis disturbance prolongs the fibroblast cell life and promotes excessive scarring. Three growth factors are thought to play a pivotal role in tissue healing and scarring transforming growth factor β, connective tissue growth factor and vascular endothelial growth factor. The article contains a review of their isoforms, role in wound healing and the possibility of their inhibition to alter the process. Matrix metalloproteinases are a protein family that can digest extracellular matrix components. Due to their influence on the tenon’s capsule

    "How wide and varied is the experience of the battlefield and how fertile the blood of warriors in raising good surgeons" Sir Clifford Allbutt (1898). With these sentiments of the medical lessons learned in war and conflict, with the background of the poem of "In Flanders Field", written by a doctor who had South African War connections, reasons (the Somme and third Ypres battles) will be given that this was indeed a "GREAT WAR" as the world history, weapons, strategy, tactics and wounding patterns had changed dramatically. These changes are still affecting all at present, as eventually the Second World War came from it, as well as the Cold "Third World" War. In this war most casualties were caused by bomb fragments and the figures were enormous. It was the war of massive troop movements (railroads), the Schlieffen plan, trench warfare, artillery, the machine guns, end of cavalry and the initiation of tanks, air warfare/reconnaissance and gas/chemical warfare. The surgical experiences of previous wars were obsolete. Urgent rethinking of surgical principles and protocols had to be devised, with the death rates of dying due to wounds, sepsis and tetanus exceeding 60 percent of all casualties. Abdominal wounds were treated conservatively, but soon there came advances in resuscitation, anaesthetics, aggressive wound and exploratory surgery, orthopaedics, plastic and reconstructive surgery, physiology, wound pathology and microbiology. All sides concentrated on ambulance stations, field hospitals and then rapid transfer to bigger referral and base hospitals. It seems that lessons learned where indeed exchanged (? by the Red Cross to all combatant medical personal). Even to the present day, frameworks of this are still used effectively (Vietnam War, Falklands War and our recent border wars). The lessons are well learned and the Torch is ours to hold up high!

    Health care-associated infections in hospitals, including surgical site infections, contribute significantly to morbidity as well as mortality. Surgical incision management (SIM) using negative pressure wound therapy (Prevena™ Incision Management System, Kinetic Concepts, Inc., San Antonio, TX, USA) is designed to cover and protect closed surgical incisions from external factors including infectious sources and local trauma, while negative pressure removes fluid and infectious material from the surgical incision. A prospective case-control study assessed wound complications in patients undergoing vascular bypass procedures, where both femoral areas were incised to gain access to the femoral arteries. SIM was placed on one femoral area while a standard postoperative wound dressing was placed on the contralateral femoral area. Eight patients were included in this pilot study. All of them required bilateral femoral artery access. During the follow-up period patients were monitored for wound complications. All wound complications requiring surgical intervention were considered significant. No significant wound complications occurred in wounds treated with SIM, compared with three significant complications in control wounds. These preliminary data would suggest a potential reduction in wound complications and no observed increase in haemorrhage in high-risk patients with severe co-morbidities undergoing vascular surgery.

    Disinfectant and antibacterial properties of ozone are utilized in the treatment of nonhealing or ischemic wounds. We present here a case of 59 years old woman with compartment syndrome following surgical treatment of stress fracture of proximal tibia with extensively infected wound and exposed tibia to about 4/5 of its extent. The knee joint was also infected with active pus draining from a medial wound. At presentation the patient had already taken treatment for 15 days in the form of repeated wound debridements and parenteral antibiotics, which failed to heal the wound and she was advised amputation. Topical ozone therapy twice daily and ozone autohemotherapy once daily were given to the patient along with daily dressings and parenteral antibiotics. Within 5 days, the wound was healthy enough for spilt thickness skin graft to provide biological dressing to the exposed tibia bone. Topical ozone therapy was continued for further 5 days till the knee wound healed. On the 15(th) day, implant removal, intramedullary nailing, and latissimus dorsi pedicle flap were performed. Both the bone and the soft tissue healed without further complications and at 20 months follow-up, the patient was walking independently with minimal disability.

  8. Chronic Wounds, Biofilms and Use of Medicinal Larvae

    Full Text Available Chronic wounds are a significant health problem in the United States, with annual associated costs exceeding $20 billion annually. Traditional wound care consists of surgical debridement, manual irrigation, moisture retentive dressings, and topical and/or systemic antimicrobial therapy. However, despite progress in the science of wound healing, the prevalence and incidence of chronic wounds and their complications are escalating. The presence & complexity of bacterial biofilms in chronic wounds has recently been recognized as a key aspect of non-healing wounds. Bacterial biofilms are sessile colonies of polymicrobial organisms (bacteria, fungus, etc. enclosed within a self-produced exopolymeric matrix that provides high levels of tolerance to host defenses, antibiotics and antiseptics. Thus, there is a need for alternative therapies to reduce biofilms in chronic wounds. In this report, we present initial findings from in vitro experiments which show that larval debridement therapy with disinfected blow fly larvae (Phaenicia sericata reduced total CFUs (6-logs of planktonic and mature biofilms of Pseudomonas aeruginosa or Staphylococcus aureus grown on dermal pig skin explants by 5-logs after 24 hours of exposure, and eliminated biofilms (no measurable CFUs after 48 hours of exposure.

    2016-08-01

    Full Text Available Triterpenes are demonstrably effective for accelerating re-epithelialisation of wounds and known to improve scar formation for superficial lesions. Among the variety of triterpenes, betuline is of particular medical interest. Topical betuline gel (TBG received drug approval in 2016 from the European Commission as the first topical therapeutic agent with the proven clinical benefit of accelerating wound healing. Two self-conducted randomized intra-individual comparison clinical studies with a total of 220 patients involved in TBG treatment of skin graft surgical wounds have been screened for data concerning the aesthetic aspect of wound healing. Three months after surgery wound treatment with TBG resulted in about 30% of cases with more discreet scars, and standard of care in about 10%. Patients themselves appreciate the results of TBG after 3 months even more (about 50% compared to standard of care (about 10%. One year after surgery, the superiority of TBG counts for about 25% in comparison with about 10%, and from the patients’ point of view, for 25% compared to 4% under standard of care. In the majority of wound treatment cases, there is no difference visible between TBG treatment and standard of care after 1 year of scar formation. However, in comparison, TBG still offers a better chance for discreet scars and therefore happens to be superior in good care of wounds.

    2016-01-01

    Wound healing is an intricate process that involves many types of cells, reaction pathways as well as chemical, physical and electrical cues. Since biochemical reactions and physiological events are pH-dependent we study here pH as an important major characteristic of the wound healing process in the presence of endogenous and exogenous electric fields. Our model gives the spatial pH distribution in a wound. In particular we isolate a number of dimensionless quantities which sets the length, energy and time scales governing the wound healing process and which can be experimentally tested. Most interesting finding is that wound pH depends on actual wound size.

    The care of wounds in exotic animal species can be a challenging endeavor. Special considerations must be made in regard to the animal's temperament and behavior, unique anatomy and small size, and tendency toward secondary stress-related health problems. It is important to assess the entire patient with adequate systemic evaluation and consideration of proper nutrition and husbandry, which could ultimately affect wound healing. This article summarizes the general phases of wound healing, factors that affect healing, and principles of wound management.

    Oxygen is an important factor for wound healing. Although several different therapies investigated the use of oxygen to aid wound healing, the results of these studies are not unequivocal. This systematic review summarizes the clinical and experimental studies regarding different oxygen therapies for promoting wound healing, and evaluates the outcomes according the methodological details. A systematic literature search was conducted using Embase, Medline, Web of Science, Cochrane, PubMed publisher, and Google Scholar libraries. Clinical and experimental studies investigating oxygen for wound healing were selected. Included articles were categorized according to the kind of therapy, study design, and wound type. The methodological details were extracted and analyzed. Sixty-five articles were identified and divided in three different oxygen therapies: Local oxygen therapy, hyperbaric oxygen therapy, and supplemental inspired oxygen therapy. More than half of the included local oxygen and hyperbaric oxygen studies had one or more significant positive outcomes, 77 and 63%, respectively. Supplemental inspired oxygen therapy during gastrointestinal and vascular surgery was more likely to have a positive result than during other surgical interventions reducing surgical site infections. These many positive outcomes promote the use of oxygen treatment in the stimulation of wound healing. However, the lack of clinical studies and vast methodological diversity made it impossible to perform a proper comparison within and between the different therapies. Further randomized clinical studies are warranted to examine the value of these therapies, especially studies that investigate the more patient-friendly oxygen dressings and topical wound oxygen therapies. Also, to achieve more solid and consistent data, studies should use more standardized methods and subjects. © 2017 by the Wound Healing Society.

  14. Successful closure of feline axillary wounds by reconstruction of the elbow skin fold.

    Brinkley, C H

    2007-02-01

    This report describes the successful closure of five chronic feline axillary wounds. The aetiology was known to be forelimb entrapment in a neck collar in three cases and was suspected in the others. Each cat underwent a single surgical procedure during which the wound was debrided, the normal structure of the elbow skin fold was restored and the remaining skin defect was closed primarily. None of the cats had undergone any previous reconstruction attempts. No postoperative complications were observed and the wounds healed uneventfully. Cats have well-developed elbow skin folds, allowing a wide range of limb motion to occur. Having a forelimb trapped in a neck collar not only creates a wound in the axilla but also disrupts the normal anatomy of the skin fold. This report demonstrates that restoring the elbow skin fold before closing the wound may improve the chances of a successful reconstruction at the first surgical intervention.

    Objective: To evaluate the clinical efficacy of greater omentum in reconstruction of refractory wounds. Methods: From August 1988 to May 2001, 20 patients with refractory wound underwent pedicle or microvascular free transfer of the greater omentum. Indications of surgery were electrical injury of the wrist and hand in 9 patients, electrical injury of the scalp and cranial bones in 3, avulsion injury of the scalp in 2, radiation-related ulcer of the chest wall in 2, ulcer and osteomyelitis following resection of the sternum sarcoma in 1, electrical injury of the abdomen in 1, bone and soft tissue defects following compound fracture of the leg in 1, and extensive scar and ulcer of the leg and footdrop following trauma in 1. Severe infection and extensive tissue necrosis were present prior to surgical operation in 12 patients. Eleven patients were treated with pedicled omental flaps, and 9 patients with free omental flaps. The size of the omental flaps ranged from 20 cm×12 cm to 38 cm×23 cm. Results: All the omental flaps survived. Healing at the first intention of the wounds was achieved in 17 cases. The on-top skin grafts resulted in partial necrosis of lipid liquefaction developed in the omentum and healed with dressing change in 2 cases. A sinus tract of osteomyelitis occurred in one case and healed after delayed excision of the necrosed bone. Follow-up study of all cases from 3 to 24 months showed no recurrent wounds and post-operative abdominal complication. Recovery with acceptable appearance and restoration of function was satisfactory. Conclusions: Greater omentum provides a well-vascularized tissue with lymphatic ducts for wound coverage. It has strong resistance against infection. It is very malleable and can be molded easily. Therefore it is an ideal tissue in filling cavities and repairing defects, especially in covering large and irregular defects that can not be treated with skin or muscle flaps.

    Given the fundamental goal of raising living standards in the longer term, much attention is paid to policies that can be expected to increase national saving. With respect to private saving, the mechanism is tax reform - a lower tax on interest income. The basic problem with this approach is that, for a given size of government, some other tax or transfer must be adjusted to finance the interest-tax cut. This fact may make it difficult to ensure that those with only labour income will share ...

  20. Negative pressure wound therapy: an evidence-based analysis.

    Science.gov (United States)

    2006-01-01

    This review was conducted to assess the effectiveness of negative pressure wound therapy. TARGET POPULATION AND CONDITION Many wounds are difficult to heal, despite medical and nursing care. They may result from complications of an underlying disease, like diabetes; or from surgery, constant pressure, trauma, or burns. Chronic wounds are more often found in elderly people and in those with immunologic or chronic diseases. Chronic wounds may lead to impaired quality of life and functioning, to amputation, or even to death. The prevalence of chronic ulcers is difficult to ascertain. It varies by condition and complications due to the condition that caused the ulcer. There are, however, some data on condition-specific prevalence rates; for example, of patients with diabetes, 15% are thought to have foot ulcers at some time during their lives. The approximate community care cost of treating leg ulcers in Canada, without reference to cause, has been estimated at upward of $100 million per year. Surgically created wounds can also become chronic, especially if they become infected. For example, the reported incidence of sternal wound infections after median sternotomy is 1% to 5%. Abdominal surgery also creates large open wounds. Because it is sometimes necessary to leave these wounds open and allow them to heal on their own (secondary intention), some may become infected and be difficult to heal. Yet, little is known about the wound healing process, and this makes treating wounds challenging. Many types of interventions are used to treat wounds. Current best practice for the treatment of ulcers and other chronic wounds includes debridement (the removal of dead or contaminated tissue), which can be surgical, mechanical, or chemical; bacterial balance; and moisture balance. Treating the cause, ensuring good nutrition, and preventing primary infection also help wounds to heal. Saline or wet-to-moist dressings are reported as traditional or conventional therapy in the

  2. Topical application of dressing with amino acids improves cutaneous wound healing in aged rats.

    2010-09-01

    The principal goal in treating surgical and non-surgical wounds, in particular for aged skin, is the need for rapid closure of the lesion. Cutaneous wound healing processes involve four phases including an inflammatory response with the induction of pro-inflammatory cytokines. If inflammation develops in response to bacterial infection, it can create a problem for wound closure. Reduced inflammation accelerates wound closure with subsequent increased fibroblast function and collagen synthesis. On the contrary, prolonged chronic inflammation results in very limited wound healing. Using histological and immunohistochemical techniques, we investigated the effects of a new wound dressing called Vulnamin that contains four essential amino acids for collagen and elastin synthesis plus sodium ialuronate (Na-Ial), compared with Na-Ial alone, in closure of experimental cutaneous wounds of aged rats. Our results showed that the application of Vulnamin dressings modulated the inflammatory response with a reduction in the number of inflammatory cells and inducible nitric oxide synthase (iNOS) immunolocalisation, while increasing endothelial nitric oxide synthase (eNOS) and transforming growth factor-beta1 (TGF-beta1) immunolocalisation. Furthermore, the dressing increased the distribution density of fibroblasts and aided the synthesis of thin collagen fibers resulting in a reduction in healing time. The nutritive approach using this new wound dressing can provide an efficacious and safe strategy to accelerate wound healing in elderly subjects, simplifying therapeutic procedures and leading to an improved quality of life. 2009 Elsevier GmbH.

    Full Text Available CONTEXT AND OBJECTIVE: Use of topical negative pressure over difficult-to-heal wounds has been studied. The objective of this study was to analyze the effects from negative pressure in the treatment of complex wounds. DESIGN AND SETTING: Case series developed at Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo. METHODS: Twenty-nine patients with complex wounds were treated with the vacuum system and then underwent a surgical procedure to close the wound. RESULTS: 85% of the skin grafts took well, and 87.5% of the local flaps were successful, thus demonstrating adequate wound preparation. The wounds were closed within shorter times than observed using other conventional treatments In two cases, the vacuum system was also used to stabilize the skin grafts over the wounds. CONCLUSIONS: Use of the vacuum method is safe and efficient for preparing wounds for surgical closure. It allows for an improvement of local wound conditions, and healthy granulation tissue develops with control over local infection.

  4. Experimental closure of gunshot wounds by fibrin glue with antibiotics in pigs

    2015-01-01

    Full Text Available Background/Aim. Gunshot wounds caused by the automatic rifle M70AB2 (AK-47 7.62 mm, after the primary surgical management, were closed with delayed primary suture during the next four to seven days. This period coincides with the fibroblastic phase of wound healing. Fibrin glue is used as a local hemostatic and as a matrix for the local dosed release of antibiotics. Antibiotics addition to fibrin glue resulted in continuous diffusion into the surrounding next 4 to 7 days. The aim of this study was to create the preconditions for gunshot wounds closing without complications by the application of fibrin glue with antibiotics 24 h after primary surgical treatment. Methods. A total of 14 pigs were wounded in the gluteofemoral region by the bullet M67, initial velocity of 720 m/s. All wounded animals were surgically treated according to the principles of the warsurgery doctrine. Seven wounds were closed with primary delayed suture four days after the primary surgical treatment (traditional approach. Fibrin glue with antibiotics was introduced in seven wounds during the primary surgical treatment and primary delayed suture was done after 24 h. The macroscopic appearance and the clinical assessment of the wound were done during the primary surgical treatment and during its revision after 24 h, as well as histopathological findings at the days 4 and 7 after wounding. Results. Gunshot wounds caused by the automatic rifle M70AB2 (AK-47 7.62 mm, and treated with fibrin glue with antibiotics after primary surgical management, were closed with primary delayed suture after 24 h. In further wound evolution there were no complications. Conclusion. Uncomplicated soft-tissue wounds caused by an automatic M70AB2 rifle may be closed primarily with delayed suture without the risk of developing complications if on revision, 24 h after primary surgery, there were no present necrotic tissues, hematoma, and any signs of infection when fibrin glue with antibiotics

  5. Do inflammatory markers portend heterotopic ossification and wound failure in combat wounds?

    2014-09-01

    After a decade of war in Iraq and Afghanistan, we have observed an increase in combat-related injury survival and a paradoxical increase in injury severity, mainly because of the effects of blasts. These severe injuries have a devastating effect on each patient's immune system resulting in massive upregulation of the systemic inflammatory response. By examining inflammatory mediators, preliminary data suggest that it may be possible to correlate complications such as wound failure and heterotopic ossification (HO) with distinct systemic and local inflammatory profiles, but this is a relatively new topic. We asked whether systemic or local markers of inflammation could be used as an objective means, independent of demographic and subjective factors, to estimate the likelihood of (1) HO and/or (2) wound failure (defined as wounds requiring surgical débridement after definitive closure, or wounds that were not closed or covered within 21 days of injury) in patients sustaining combat wounds. Two hundred combat wounded active-duty service members who sustained high-energy extremity injuries were prospectively enrolled between 2008 and 2012. Of these 200 patients, 189 had adequate followups to determine the presence or absence of HO, and 191 had adequate followups to determine the presence or absence of wound failure. In addition to injury-specific and demographic data, we quantified 24 cytokines and chemokines during each débridement.

    2017-01-01

    Significance: Rapid recruitment and activation of macrophages may accelerate wound healing. Such accelerated healing was observed in wounds and burns of experimental animals treated with α-gal nanoparticles. Recent Advances: α-Gal nanoparticles present multiple α-gal epitopes (Galα1-3Galβ1-4GlcNAc-R). α-Gal nanoparticles applied to wounds bind anti-Gal (the most abundant antibody in humans) and generate chemotactic complement peptides, which rapidly recruit macrophages. Fc/Fc receptor interaction between anti-Gal coating the α-gal nanoparticles and recruited macrophages activates macrophages to produce cytokines that accelerate healing. α-Gal nanoparticles applied to burns and wounds in mice and pigs producing anti-Gal, decreased healing time by 40–60%. In mice, this accelerated healing avoided scar formation. α-Gal nanoparticle-treated wounds, in diabetic mice producing anti-Gal, healed within 12 days, whereas saline-treated wounds became chronic wounds. α-Gal nanoparticles are stable for years and may be applied dried, in suspension, aerosol, ointments, or within biodegradable materials. Critical Issues: α-Gal nanoparticle therapy can be evaluated only in mammalian models producing anti-Gal, including α1,3-galactosyltransferase knockout mice and pigs or Old World primates. Traditional experimental animal models synthesize α-gal epitopes and lack anti-Gal. Future Directions: Since anti-Gal is naturally produced in all humans, it is of interest to determine safety and efficacy of α-gal nanoparticles in accelerating wound and burn healing in healthy individuals and in patients with impaired wound healing such as diabetic patients and elderly individuals. In addition, efficacy of α-gal nanoparticle therapy should be studied in healing and regeneration of internal injuries such as surgical incisions, ischemic myocardium following myocardial infarction, and injured nerves.

    Wounds are an excellent example of how the field of dermatology represents a cross-section of many medical disciplines. For instance, wounds may be caused by trauma, vascular insufficiency, and underlying medical conditions, such as diabetes, hypertension, and rheumatologic and inflammatory disease. This continuing medical education article provides an overview of wound healing and the pathophysiology of chronic wounds and reviews the broad differential diagnosis of chronic wounds. It also describes the initial steps necessary in evaluating a chronic wound and determining its underlying etiology. Copyright © 2015 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    Full Text Available Management of burn injury has always been the domain of burn specialists. Since ancient time, local and systemic remedies have been advised for burn wound dressing and burn scar prevention. Management of burn wound inflicted by the different physical and chemical agents require different regimes which are poles apart from the regimes used for any of the other traumatic wounds. In extensive burn, because of increased capillary permeability, there is extensive loss of plasma leading to shock while whole blood loss is the cause of shock in other acute wounds. Even though the burn wounds are sterile in the beginning in comparison to most of other wounds, yet, the death in extensive burns is mainly because of wound infection and septicemia, because of the immunocompromised status of the burn patients. Eschar and blister are specific for burn wounds requiring a specific treatment protocol. Antimicrobial creams and other dressing agents used for traumatic wounds are ineffective in deep burns with eschar. The subeschar plane harbours the micro-organisms and many of these agents are not able to penetrate the eschar. Even after complete epithelisation of burn wound, remodelling phase is prolonged. It may take years for scar maturation in burns. This article emphasizes on how the pathophysiology, healing and management of a burn wound is different from that of other wounds.

    Skin-wound healing is an orchestrated biological phenomena consisting of three sequential phases, inflammation, proliferation, and maturation. Many biological substances are involved in the process of wound repair, and this short and simplified overview of wound healing can be adopted to determine wound vitality or wound age in forensic medicine. With the development of genetically engineered animals, essential molecules for skin-wound healing have been identified. Especially, cytokines, and growth factors are useful candidates and markers for the determination of wound vitality or age. Moreover, bone marrow-derived progenitor cells would give significant information to wound age determination. In this review article, some interesting observations are presented, possibly contributing to the future practice of forensic pathologists. Copyright © 2010. Published by Elsevier Ireland Ltd.

    Khodov, A M; Zolotov, A S; Filipchenkov, L S

    2012-01-01

    Specific features and outcomes of wounds with a traumatic weapon of self-defense "Osa" were analyzed in 24 patients. Mean age of the wounded was from 21 to76 years. In 20 patients there was a single wound, in 4 patients it was multiple, in 7--blunt, in 12--perforating and 5 patients had gutter wounds. All the patients were treated according to the principles of field military surgery. Five patients had severe wounds: penetrating fracture of the skull (2 of them died), fracture of the shoulder (1 case), injury of the main artery (1 case), of the pleura (1 case). The wounds were closed up by primary intention in 19 patients, by second intention in 4 patients. The authors' experience shows that a traumatic weapon of self-defense "Osa" rather often caused permanent harm to health and can be mortal. Active surgical strategy in treatment of such patients prevents the development of serious infectious complications.

  13. Kinetic and Reaction Pathway Analysis in the Application of Botulinum Toxin A for Wound Healing

    2012-01-01

    Full Text Available A relatively new approach in the treatment of specific wounds in animal models and in patients with type A botulinum toxin is the focus of this paper. The indications or conditions include traumatic wounds (experimental and clinical, surgical (incision wounds, and wounds such as fissures and ulcers that are signs/symptoms of disease or other processes. An objective was to conduct systematic literature searches and take note of the reactions involved in the healing process and identify corresponding pharmacokinetic data. From several case reports, we developed a qualitative model of how botulinum toxin disrupts the vicious cycle of muscle spasm, pain, inflammation, decreased blood flow, and ischemia. We transformed this model into a minimal kinetic scheme for healing chronic wounds. The model helped us to estimate the rate of decline of this toxin's therapeutic effect by calculating the rate of recurrence of clinical symptoms after a wound-healing treatment with this neurotoxin.

    2016-01-01

    Negative pressure wound therapy (NPWT) has been widely used in the adult patient, contrary to what happens in children, with just a few long series papers. NPWT avoids long and expensive hospital admissions, reducing the hospital costs; it also decreases the family dynamics and allows for an early return to everyday activities. In this article, we present three clinical cases consisting of a toddler, a child and a teenager with complex wounds treated with NPWT in the pediatric surgery department of the Virgen de las Nieves University Hospital in Granada. The results were excellent, with a good adherence to treatment in all cases, achieving a complete closure in two cases; the third case needed a deferred surgical closure after surgical site preparation, and showed a decrease of the wound size after the NPWT. Moreover, successful pain management was achieved during the wound cleansing, which was done under an ambulatory regime. No general anesthesia was needed. From our experience, we propose the NPWT as an alternative therapy to the classic surgical approach for this type of complex lesions in children, which offers the same advantages and results than in adults.

    2017-08-01

    Despite advances in endovascular surgery, lower extremity arterial bypass (LEB) remains the gold standard treatment for severe, symptomatic Peripheral Arterial Disease. With recent changes in health care, there has been an increasing emphasis on reducing the hospital length of stay (LOS). The purpose of this study was to identify the postoperative complications, which occur after discharge from hospital and to find risk factors for developing such complications. The 2013 lower extremity revascularization-targeted American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database and generalized 2013 general and vascular surgery ACS-NSQIP Participant Use File were used for this study. Patient, diagnosis, and procedure characteristics of patients undergoing LEB were assessed. Postoperative complications were identified and their relationship to the median discharge date. Univariate and multivariable analyses were performed to identify the risk factors associated with developing these complications. A prediction model was then created to accurately predict the risk of developing such complications. A total of 2,646 patients (65% male and 35% female) were identified in the NSQIP database that underwent LEB during the year 2013. Median LOS was 6 days. Most common significant complications after hospital discharge were wound infection/complication (13.7%, mean days from operation [MDAO] = 15 days), wound disruption/dehiscence (1.6%, MDAO = 15 days), and organ space surgical site infections (0.6%, MDAO = 16 days). Multivariable analysis showed the following factors associated with wound infection: wound disruption/dehiscence (odds ratio [OR]: 16, confidence interval [CI]: 7.09-36.07, P 300 min vs. 0-170 min (OR: 1.98, CI: 1.32-2.96, P = 0.008), prior ipsilateral percutaneous intervention involving currently treated segment vs. prior ipsilateral bypass involving currently treated segment (OR: 1.98, CI: 1.30-3.01, P = 0

    2013-12-01

    Wound healing is a fundamental response to tissue injury and natural products accelerate the healing process. Here, we have explored the efficacy of topical administration of an ointment, prepared by methanolic extract of Jasminum grandiflorum L. (Oleaceae) leaves, on cutaneous wound healing in rats. The topical application of the Jasminum ointment on full thickness excision wounds accelerated the healing process. Tissue growth and collagen synthesis were significantly higher determined by total hydroxyl proline, hexosamine, protein and DNA content. The response was concentration- and time-dependent, when observed on days 4, 8 and 12 after wound creation. The rate of wound healing was faster as determined by wound contraction, tensile strength and other histopathological changes. In addition, this ointment also raised the activity of superoxide dismutase (SOD) and catalase (CAT) with high GSH content and low lipid peroxidation products in wound tissue. Thus, it could be suggested that the ointment from the methanolic extract of J. grandiflorum leaf improves the rate of wound healing by enhancing the rate of collagen synthesis and also by improving the antioxidant status in the newly synthesised healing wound tissue. © 2012 The Authors.

    2005-11-01

    Even though the discussion for desisting from wound drainage has arisen, this is not reflected in the reality of surgical treatment. In more than 90% of all procedures wound drainage is used. It remains to be proven whether suction drainage actually is superior to gravity drainage in everyday use. In a random study with 200 patients it was proven that suction drainage shows no significant advantage in liquid quantum, haematoma and the frequency of complications. We conclude that the economically favourable gravity drainage can replace the more expensive suction drainage in most cases.

    Full Text Available Objective: Post-operative laminectomy wounds are frequently accompanied by seromas. Post-operative wound drainage may be colonized or infected. The differentiation of wound colonization from infection is difficult for non-infectious disease physicians. Methods: External chart reviewers classified 31/1531 laminectomies (over three years as post-operative wound infections. We re-evaluated these cases using infectious disease criteria, i.e., while pathogens may be cultured from both colonized and infected wounds, only wound infections have a purulent discharge with abundant white blood cells (WBCs on Gram stain. Colonized wounds have positive wound cultures but no/few WBCs on Gram stain. Results: We found only 11/31 actual wound infections, the remainder were not bona fide wound infections, but were colonized seromas. Conclusion: Post-laminectomy colonized seromas that are culture positive for one or more organisms often mimic wound infections. In the era of public reporting of nosocomial infections, it is important that external reviewers differentiate colonization from infection to provide regulatory agencies with accurate data.

    2012-09-01

    Understanding wound healing involves more than simply stating that there are the three phases of inflammation, proliferation and maturation. Wound healing is a complex series of actions, reactions and interactions among cells and mediators in a sequential and simultaneously ongoing temporal process within a spatial frame. At first this article will attempt to provide a concise summary of the events, cellular components and main influential mediators of wound healing over time. Secondly, the pathophysiology of chronic non-healing wounds is described where an imbalance of stimulating and inhibiting factors causes failure of healing. The most relevant extrinsic and intrinsic determinants are described and related to the cellular and molecular level of disturbed wound healing. A basic understanding of wound healing is a prerequisite for any prophylactic or therapeutic maneuver to maintain or re-establish wound equilibrium to give a satisfactory healing trajectory.

    Full Text Available While report of animal bites contaminating wounds is reported commonly, direct wound contamination with squirrel flesh has never been reported in the literature. The patient suffered an accidental self-inflicted gunshot wound that drove squirrel flesh and buck shot deep within his right buttock. This case outlines his hospital course and wound treatment. The patient was treated with ten days of broad spectrum antibiotics, extensive debridement of the wound in the operating room, and further treatment of the wound with a vacuum dressing system. While squirrel tissue and buckshot had to be removed from the wound on day six of the hospital stay, the patient remained afebrile without signs or symptoms of systemic illness.

    2015-02-01

    The aim of this article was to identify the literature that examined and explored physical and psychological morbidity and patient and family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. A systematic review of the literature using the databases MEDLINE, CINAHL and EMBASE was undertaken. The papers were examined using title and abstract for relevance to the primary and secondary outcomes. The primary outcome of interest was family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. The search yielded 275 records after removing any duplicates; eight studies were considered eligible and were reviewed as full text. Following full review, none of the studies was included in this article. To conclude, there were no papers that investigated or examined the concept of resilience in relation to the management of acute post-surgical orthopaedic wounds. Four of the papers identified, following the review process, did discuss quality of life outcomes and how these may be improved following wound development; most papers focused on the management of chronic wounds. It is apparent from the review that there is no evidence currently available that explores patient and family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery.

    Bocchiotti, Maria A.; Baglioni, Elisabetta A.; Spaziante, Luca; Frenello, Ambra

    2016-01-01

    Background: The postoperative dressing in patients undergoing thigh lift is often difficult, not very resistant to movement, and uncomfortable for the patient, and often exposes surgical site to infection, maceration, or delay in wound healing. Methods: We included 40 patients in a case–control crossover study with no period effects, who were treated both by Aquacel Surgical and a traditional wound dressing. Surveys with a 10-point scale evaluation were used to assess nontraumatic removal level, ease of application, adhesion, and strength of the 2 treatments. We reported the number of days necessary for wound healing, the number of infection cases, and wound-related complications. Costs of the 2 medications were also considered. Ten days after surgery, patients answered a questionnaire with 6 multiple-choice questions to assess comfort, pain at dressing change, pruritus, strength, and number of dressing changes. Results: Compared with controls, surveys revealed Aquacel Surgical to be less traumatic to remove, easier to apply, and to be more adherent and stronger. Significant acceleration of the wound healing was also evident with Aquacel Surgical compared with the traditional dressing. Nonsignificant differences were reported about the risk of infection and wound-related complications between the 2 treatments. A statistical analysis of costs revealed that Aquacel Surgical is significantly more expensive than the traditional medication. Conclusion: We recommend the use of Aquacel Surgical in all the surgery procedures where the risk of wound dehiscence and maceration is high.

    Full Text Available PURPOSE: To demonstrate the effects of the use of sunflower seed oil on the treatment of skin wounds. METHODS: Eighteen male Saint Inês lambs were divided in 3 groups according to the pos-operative (7, 14 and 21 days. After antisepsis and local anestesia, two 4cm² wounds on each side of the thoracic region, close to the scapule were surgically produced. The experimental wounds were treated with sunflower seed oil, with high concentration of linoleic acid (LA, and the control ones with sterilized Vaseline. Biopsies of the pos-operative wounds tissue were performed on the 7th, 14th, 21st days and histologically evaluated. RESULTS: Topic application of sunflower seed oil accelerated healing process at the 7th and 21st days, reducing wound area and increasing wound contraction. Granulation tissue increased faster on treated wounds. The epidermis of the treated wounds was completely recovered when compared to control wounds. CONCLUSION: The topic use of sunflower seed oil accelerated the healing process, and it can be used as an alternative therapy on second intention wound healing.

    2016-04-01

    Full Text Available BACKGROUND Wound dehiscence is a mental, financial and physical trauma to patients and has an equivalent effect on surgeon too. Wound dehiscence etches profound morbidity in a patient’s life. There arises an expanding demand in the cost of care, both in terms of increased hospital stay and manpower in nursing and managing of burst wound and its complications. Thus understanding of factors contributing to dehiscence, correctable measures and precautionary steps are very much essential in day-to-day practice of all surgeons. This ignited our thoughts to conduct a study and understand wound healing and dehiscence in a better way. AIM This study was made to find the factors that significantly contribute to wound dehiscence in midline emergency exploratory laparotomy. METHODS The study was conducted in 213 patients who underwent midline emergency exploratory laparotomy in Silchar Medical College and Hospital in Barak Valley, Assam, India, from March 2015 to February 2016. Factors such as age, preoperative albumin, body mass index, haemoglobin, post-operative pulmonary complication, diabetes mellitus, duration of surgery, time of presentation, intraabdominal sepsis/wound infection, raised intra-abdominal pressure, raised creatinine, ascites and malignancy were observed and analysed with odds ratio and P value. RESULTS AND CONCLUSION Risk factors for abdominal wound dehiscence identified in this study include anaemia, hypoalbuminemia, post-operative pulmonary complications, increased intra-abdominal pressure, intra-abdominal sepsis/wound infection, delayed presentation and malignancy.

    Full Text Available CONTEXT: Despite the absence of symptoms in the majority of patients carrying lead bullet fragments in their bodies, there needs to be an awareness of the possible signs and symptoms of lead intoxication when bullets are lodged in large joints like knees, hips and shoulders. Such patients merit closer follow-up, and even surgical procedure for removing the fragments. OBJECTIVE: To describe a patient who developed clinical lead intoxication several years after a gunshot wound. DESIGN: Case report. CASE REPORT: A single white 23-year-old male, regular job as a bricklayer, with a history of chronic alcohol abuse, showed up at the emergency department complaining of abdominal pain with colic, weakness, vomiting and diarrhea with black feces. All the symptoms had a duration of two to three weeks, and had been recurrent for the last two years, with calming during interval periods of two to three weeks. Abdominal radiograms showed a bullet lodged in the left hip, with a neat bursogram of the whole synovial capsule. A course of chelating treatment using calcium versenate (EDTACaNa2 intravenously was started. After the chelation therapy the patient had recurrence of his symptoms and a radical solution for the chronic mobilization of lead was considered. A hip arthroplasty procedure was performed, leading to complete substitution of the left hip.

    Full Text Available ABSTRACT: To evaluate the therapeutic contribution of MSC intravenous infusion to surgical wound healing in dexamethasone-immunosuppressed rats, thirty-five rats were randomly divided into 2 groups: in the Control Group (CG, five rats received normal saline as 0.2ml subcutaneous (SC injections every 24 hours, for 30 consecutive days and, in the Dexamethasone Group (DG, 30 rats were given 0.2mL subcutaneous dexamethasone (0.1mg kg-1 every 24 hours, for 30 consecutive days. After 30 days, all rats underwent surgery to create an experimental skin wound. The 30 animals of the DG group were divided into two equal groups, which received different treatments: the dexamethasone group (DG received a single application of 0.5ml normal saline, via the intravenous route (IV, 48 hours after wound creation; and the Mesenchymal Stem Cells Dexamethasone group (MSCDG received MSC transplantation at a concentration of 9x106 cells in a single IV application, 48 hours after wound creation. The surgical wounds of CG rats closed on average 14.75 days after creation and DG rats had wounds closed within 22 days; whereas, the surgical wounds of MSCDG rats were closed in 14 days. MSC infusion in dexamethasone-immunosuppressed patients contributed positively to epithelial healing in less time.

    Swain, Digendranath; Gupta, Anurag

    2016-11-07

    A cutaneous wound may rupture during healing as a result of stretching in the skin and incompatibility at the wound-skin interface, among other factors. By treating both wound and skin as hyperelastic membranes, and using a biomechanical framework of interfacial growth, we study rupturing as a problem of cavitation in nonlinear elastic materials. We obtain analytical solutions for deformation and residual stress field in the skin-wound configuration while emphasizing the coupling between wound rupture and wrinkling in the skin. The solutions are analyzed in detail for variations in stretching environment, healing condition, and membrane stiffness.

    Poor wound healing is an important surgical complication. At-risk wounds must be identified early and monitored appropriately. Wound surveillance is frequently inadequate, leading to increased rates of surgical site infections (SSIs). Although the literature demonstrates that risk factor identification reduces SSI rates, no studies have focused on wound management at a junior level. Our study assesses documentation rates of patient-specific risk factors for poor wound healing at a large district general hospital in the UK. It critically evaluates the efficacy of interventions designed to promote surveillance of high-risk wounds. We conducted a full-cycle clinical audit examining medical records of patients undergoing elective surgery over 5 days. Interventions included education of the multidisciplinary team and addition of a Wound Healing Risk Assessment (WHRA) checklist to surgical admissions booklets. This checklist provided a simple stratification tool for at-risk wounds and recommendations for escalation. Prior to interventions, the documentation of patient-specific risk factors ranged from 0·0% to 91·7% (mean 42·6%). Following interventions, this increased to 86·4-95·5% (mean 92·5%), a statistically significant increase of 117·1% (P wound healing is inadequate. We have shown the benefit of introducing interventions to increase risk factor awareness. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Lacerations, abrasions, burns, and puncture wounds are common in the outpatient setting. Because wounds can quickly become infected, the most important aspect of treating a minor wound is irrigation and cleaning. There is no evidence that antiseptic irrigation is superior to sterile saline or tap water. Occlusion of the wound is key to preventing contamination. Suturing, if required, can be completed up to 24 hours after the trauma occurs, depending on the wound site. Tissue adhesives are equally effective for low-tension wounds with linear edges that can be evenly approximated. Although patients are often instructed to keep their wounds covered and dry after suturing, they can get wet within the first 24 to 48 hours without increasing the risk of infection. There is no evidence that prophylactic antibiotics improve outcomes for most simple wounds. Tetanus toxoid should be administered as soon as possible to patients who have not received a booster in the past 10 years. Superficial mild wound infections can be treated with topical agents, whereas deeper mild and moderate infections should be treated with oral antibiotics. Most severe infections, and moderate infections in high-risk patients, require initial parenteral antibiotics. Severe burns and wounds that cover large areas of the body or involve the face, joints, bone, tendons, or nerves should generally be referred to wound care specialists.

    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

    Full Text Available The aim of present study was to determine the microbial pattern and a significance of local pustular immune factors for the progression of local pyogenic infection in surgical patients. To these purpose, specific infectious pathogens were identified and scored by means of conventional microbiological methods in the patients with pyogenic inflammatory diseases of skin and subcutaneous fat tissues. The numbers of purulent leukocytes were determined in the pustular exudates, and concentrations of TNFα, IL-1β, IL-8, IFN-γ, IL-4, IL-1ra, IgM, IgG, and IgA were measured in the samples, using enzyme immunoassay techniques. Appropriate parameters of effluents obtained from "clean" (non-infected surgical lesions were taken as сontrols. It has been shown that Staphylococcus aureus plays a leading role in etiology of bacterial infections in our patients. The amounts of blood cells in pustular samples showed a direct and significant correlation with number of viable microorganisms derived from the effluent. Purulent wound exudates were characterized by high IL-1β and IL-8 concentrations, along with relatively low TNFα levels, as compared with "clean" wounds. Mean amounts of IgG in the pustular contents of dissected lesions proved to be five-fold higher that IgG levels in sterile incisions. As compared with young individuals, the elderly persons are characterized by lesser TNFα production, as well as by more active IL-8 synthesis in the areas of bacterial inflammation. The indexes of local immunity show sufficient differences between the areas of suppurative inflammation and sterile wound lesions.

Two principles in medical economics central to the Affordable Care Act (ACA were dealt blows by recently published studies. The first principle is the belief that economies of scale will result in lower prices. The theory is that larger insurers will have lower prices because they are more administratively efficient.

    For bum patients, topical treatment is as important as systemic treatment. Reasonable and timely wound treatment will influence the homeostatic equilibrium, and the progression, the prognosis, and the outcome of the disease. The therapeutic principle should be varied for wounds with different depth of injury. But avoiding or at least alleviating infection, and accelerating healing period, were the common principles. In common, the medication for local wound treatment includes: topical antiseptic, surgical dressing products, artificial skins, and so on.Ideal topical antiseptic should have the following zcharacteristics: the antimierobial spectrum is broad, including Pseudomonas aeruginosa and MRSA; be able to penetrate necrotic tissue; does not induce drug resistatance easily; no local irritating effect and not painful; no side effect to body; can be applied easily; low cost. The functions of surgical dressing in clude: protect the wounds, keep the microcirculation open, and accelerate wound healing. Artificial skin has been used as the autoskin carrier in skin transplantation operation for large burn area to protect the autoskin grafts, accelerate wound healing, and cover the wounds temporarily. Bums therapy has developed for 50 years in China, the study of local treatment for burn wounds has also experienced a tortuous path of trial and error. This review might contribute some ideas future research.

    Measuring the prevalence of wounds within health care systems is a challenging and complex undertaking. This is often compounded by the clinicians' training, the availability of the required data to collect, incomplete documentation and lack of reporting of this type of data across the various health care settings. To date, there is little published data on wound prevalence across regions or states. This study aims to identify the number and types of wounds treated in the Gippsland area using the Mobile Wound Care (MWC™) program. The MWC program has enabled clinicians in Gippsland to collect data on wounds managed by district nurses from four health services. The main outcomes measured were patient characteristics, wound characteristics and treatment characteristics of wounds in Gippsland. These data create several clinical and research opportunities. The identification of predominant wound aetiologies in Gippsland provides a basis on which to determine a regional wound prospective and the impact of the regional epidemiology. Training that incorporates best practice guidelines can be tailored to the most prevalent wound types. Clinical pathways that encompass the Australian and New Zealand clinical practice guidelines for the management of venous leg ulcers can be introduced and the clinical and economical outcomes can be quantitatively measured. The MWC allows healing times (days) to be benchmarked both regionally and against established literature, for example, venous leg ulcers.

The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is limited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

    2016-01-01

    To analyze current understanding of the factors that contribute to raised intraocular pressure (IOP) in patients with uveitis. A pubmed literature review was carried out using words including "uveitic glaucoma", "IOP AND uveitis", "ocular hypertension AND uveitis", "inflammation AND glaucoma", "aqueous dynamics" AND "glaucoma/uveitis". Of the two studies looking at the aqueous dynamics in experimentally induced uveitis, both found aqueous flow decreased acutely, and one found that uveoscleral outflow increased. This is likely to reflect the types of uveitis that present acutely with hypotony. A study examining patients with Fuch's heterochromic cyclitis found no difference in aqueous flow or uveoscleral outflow. No studies have examined aqueous dynamics in types of uveitis that present with acutely raised IOP. Levels of prostaglandins rise in acute uveitis, which has been shown to increase uveoscleral and trabecular outflow, without affecting aqueous flow. Studies have demonstrated that raised levels of trabecular protein reduce trabecular outflow. Steroid treatment, inflammatory cells, free radicals and enzymes are also likely to contribute to the development of raised pressure. When considering the impact of the pathogenesis of raised pressure in uveitis on its treatment, prostaglandins may provide good intraocular pressure control, but there are concerns regarding their theoretical ability to worsen the inflammatory response in uveitis. Studies have not conclusively proven this to be the case. Surgical success rates vary, but trabeculectomy plus an antimetabolite, deep sclerectomy plus an antimetabolite, and Ahmed valve surgery have been used. Uveitic glaucoma is caused by a number of different diseases, some of which present with acute hypotony, others with acutely raised IOP, and others which demonstrate an increase in IOP over time. Further studies should be carried out to examine the differing pathogenesis in these types of diseases, and to establish the

    There are a wide variety of dressing techniques and materials available for management of both acute wounds and chronic non-healing wounds. The primary objective in both the cases is to achieve a healed closed wound. However, in a chronic wound the dressing may be required for preparing the wound bed for further operative procedures such as skin grafting. An ideal dressing material should not only accelerate wound healing but also reduce loss of protein, electrolytes and fluid from the wound,...

    Eight burn wound sepsis patients, in which 6 cases were diagnosed as MODS and two as septic shock, were treated consecutively in our hospital from September 1997 to October 1998. The plasma concentration of IL-6, IL-8, TNFα and LPS were assayed before and after surgical intervention, as well as when the patients' vital signs became stable. The results showed: ①The patients' conditions abruptly deteriorated when the burn wound sepsis emerged;②The major cause related to burn wound sepsis was extensive burn injuries, with large areas of deep burn remaining open; ③Although wound swabs taken on admission revealed the presence of colonization by many pathogenic bacteria, Pseudomonas aeruginosa was one of the most frequent bacteria isolated from the subeschar tissue; ④The plasma concentrations of IL-6, IL-8, TNF and LPS before surgical intervention were significantly higher than that after surgical intervention (P<0.05) ;⑤The lowest level of the inflammatory mediators was observed when the patients' conditions became stable, as compared with before surgical intervention (P<0. 001).These findings suggest that the clinical characteristics of burn wound sepsis are abrupt deterioration of the general condition and prominent septic symptoms, often complicated by MODS. The main cause of burn wound sepsis is the presence of a large area of open deep burn wounds, which should be excised and covered early. LPS and pro-inflammatory mediators play an important role in the pathogenesis of burn wound sepsis. Although success in treating these patients is the result of appropriate application of multiple treatments, early, aggressive and thorough surgical excision of invasive burn infectious tissue and closure of wound play a crucial role in the successful treatment of patients complicated by burn wound sepsis. Other treatments are adjuvant but also important.

    Full Text Available Abstract Background Surgeons usually witness only the limb-threatening stages of infected, closed pedal puncture wounds in diabetics. Given that this catastrophic outcome often represents failure of conservative management of pre-infected wounds, some suggest consideration of invasive intervention (coring or laying-open for pre-infected wounds in hope of preventing contamination from evolving into infection, there being no evidence based guidelines. However, an invasive pre-emptive approach is only justifiable if the probability of progression to catastrophic infection is very high. Literature search revealed no prior studies on the natural history of closed pedal puncture wounds in diabetics. Methods A survey was conducted via an interviewer-administered questionnaire on 198 adult diabetics resident in the parish of St. James, Jamaica. The sample was selected using a purposive technique designed to mirror the social gradient and residential distribution of the target population and is twice the number needed to detect a prevalence of puncture wounds of 14% with a range of 7-21% in a random sample of the estimated adult diabetic population. Results The prevalence of a history of at least one closed pedal puncture wound since diagnosis of diabetes was 25.8% (CI; 19.6-31.9%. The only modifiable variable associated at the 5% level of significance with risk of pedal puncture wound, after adjustment by multivariable logistic regression, was site of interview/paying status, a variable substantially reflective of income more so than quality-of-care. Of 77 reported episodes of closed pedal puncture wound among 51 participants, 45.4% healed without medical intervention, 27.3% healed after non-surgical treatment by a doctor and 27.3% required surgical intervention ranging from debridement to below-knee amputation. Anesthetic foot (failure to feel the puncture and sole of the forefoot as site of puncture were the variables significantly associated with

  13. Increased collagen synthesis rate during wound healing in muscle.

    Shaobo Zhou

    Full Text Available Wound healing in muscle involves the deposition of collagen, but it is not known whether this is achieved by changes in the synthesis or the degradation of collagen. We have used a reliable flooding dose method to measure collagen synthesis rate in vivo in rat abdominal muscle following a surgical incision. Collagen synthesis rate was increased by 480% and 860% on days 2 and 7 respectively after surgery in the wounded muscle compared with an undamaged area of the same muscle. Collagen content was increased by approximately 100% at both day 2 and day 7. These results demonstrate that collagen deposition during wound healing in muscle is achieved entirely by an increase in the rate of collagen synthesis.

    It is well documented that psychological stress impairs wound healing in humans and rodents. However, most research effort into influences on wound healing has focused on factors that compromise, rather than promote, healing. In the present study, we determined if positive social interaction, which influences hypothalamic-pituitary-adrenal (HPA) axis activity in social rodents, promotes wound healing. Siberian hamsters received a cutaneous wound and then were exposed to immobilization stress. Stress increased cortisol concentrations and impaired wound healing in isolated, but not socially housed, hamsters. Removal of endogenous cortisol via adrenalectomy eliminated the effects of stress on wound healing in isolated hamsters. Treatment of isolated hamsters with oxytocin (OT), a hormone released during social contact and associated with social bonding, also blocked stress-induced increases in cortisol concentrations and facilitated wound healing. In contrast, treating socially housed hamsters with an OT antagonist delayed wound healing. Taken together, these data suggest that social interactions buffer against stress and promote wound healing through a mechanism that involves OT-induced suppression of the HPA axis. The data imply that social isolation impairs wound healing, whereas OT treatment may ameliorate some effects of social isolation on health.

    Solid protein solder-doped polymer membranes were developed for laser-assisted tissue repair. Biodegradable polymer membranes of controlled porosity were fabricated with poly(L-lactic-co-glycolic acid) (PLGA), poly(ethylene glycol) (PEG), and salt particles, using a solvent-casting and particulate-leaching technique. The membranes provided a porous scaffold that readily absorbed the traditional protein solder composed of serum albumin, indocyanine green dye, and de-ionized water. In vitro investigations were conducted to assess the influence of various processing parameters on the strength of tissue repairs formed using the new membranes. These parameters included PLGA copolymer and PLGA/PEG blend ratios, membrane pore size, initial albumin weight fraction, and laser irradiance used to denature the solder. Altering the PLGA copolymer ratio had little effect on repair strength, however such variations are known to influence the degradation rate of the membranes. The repair strength increased with increased membrane pore size and bovine serum albumin concentration. The addition of PEG during the membrane casting stage increased the flexibility of the membranes but not necessarily the repair strength. Typically, the repair strength increased with increasing irradiance from 12 to 18 W/cm2. The new solder-doped polymer membranes provided all of the benefits associated with solid protein solders including high repair strength and improved edge coaptation. In addition, the flexible, moldable nature of the new membranes offers the capability of tailoring the membranes to a wide range of clinically relevant geometries.

    Multiple comorbidities and environmental factors increase the complications of incisional wounds in patients. It was demonstrated in previous prospective and randomized studies that negative pressure wound therapy (NPWT) reduced wound infection and other complications in clean, closed surgical incisions. In this case report, the Prevena incision management system was implemented on the clean, closed surgical incision of a 52-year-old female patient, who was given a renal transplantation from cadaver postoperatively in the operating theater. It was removed from the patient on the fifth day after the operation. Following the removal of Prevena, the wound and surrounding skin of the patient were observed. Wound healing was complete, and no skin lesion or tool-related complication was found around the wound due to NPWT. The Prevena NPWT system can be conveniently and safely implemented on the operational incision in renal transplant recipients in order to prevent surgical wound complications.

One hundred seventeen cases comprised of abscesses (n=51, secondary peritonitis (n=25, necrotizing fascitis (n=22 and wounds with devitalized tissues (n=19 were studied. The number of microorganisms isolated per lesion was highest in secondary peritonitis (2.32. The aerobe/ anaerobe ratio was 0.81 in secondary peritonitis and 1.8 in necrotizing fascitis. Most secondary peritonitis (80%, necrotizing fascitis (75% and wounds with devitalized tissues (66.7% were polymicrobial. Common microorganisms isolated in our study were E. coli, Staphylococcus aureus, Klebsiella spp., Pseudomonas aeruginosa, Bacteroides fragilis and Peptostreptococcus spp. The most effective antibiotics for S. aureus were clindamycin (79.1% and cefuroxime (70.8%. For Gram-negatives (Klebsiella spp., E. coli and Proteus spp., the most effective antibiotics were cefotaxime, ceftizoxime, amikacin and ciprofloxacin. Pseudomonas aeruginosa was maximally sensitive to amikacin (35.2% and ciprofloxacin (35.2%. The greatest degree of multidrug resistance to all the drugs was found in P. aeruginosa (52.9%, followed by Klebsiella spp. (33.3%, Proteus spp. (33.3%, E. coli (22.2%, and S. aureus (12.5%. All the anaerobes that we isolated were 100% sensitive to metronidazole and chloramphenicol, followed by clindamycin (95% to 100%. Apart from antibiotic therapy, non-antimicrobial methods, such as hyperbaric oxygen therapy and debridement also play an important role in the treatment of surgical infections.

For Gram-negatives (Klebsiella spp., E. coli and Proteus spp., the most effective antibiotics were cefotaxime, ceftizoxime, amikacin and ciprofloxacin. Pseudomonas aeruginosa was maximally sensitive to amikacin (35.2% and ciprofloxacin (35.2%. The greatest degree of multidrug resistance to all the drugs was found in P. aeruginosa (52.9%, followed by Klebsiella spp. (33.3%, Proteus spp. (33.3%, E. coli (22.2%, and S. aureus (12.5%. All the anaerobes that we isolated were 100% sensitive to metronidazole and chloramphenicol, followed by clindamycin (95% to 100%. Apart from antibiotic therapy, non-antimicrobial methods, such as hyperbaric oxygen therapy and debridement also play an important role in the treatment of surgical infections.

    The article considers the characteristics of surgical care to warriors of Russian army during 1812 Great Patriotic War. Such conditions are analyzed as damaging action of French weapons, types of combat wounds, organization and forces of military sanitary service of Russian troops, surgeons' support with means of supplying surgical care to the wounded and arsenal of surgical aids. On the basis of given materials analysis a preliminary conclusion is made that surgical care in Russian army in 1812 not only was on the sufficiently high level but it played a specified role in the victory of Russian weapon.

    Surgical resection in locally advanced breast cancer produces large defects that may not be suitable for primary closure. Immediate reconstruction is controversial and presents a complicated scenario for breast surgeons and plastic surgeons. In this study, a different design was planned for the latissimus dorsi musculocutaneous flap with primary closure in V-Y for the correction of major lesions in the anterior chest wall. Twenty-five patients underwent immediate locally advanced breast cancer reconstruction with a V-Y latissimus dorsi musculocutaneous flap. This flap was raised from adjacent tissue located on the lateral and posterior thoracic region and presented a triangular shape whose base was the lateral aspect of the mastectomy wound. The technique was indicated in patients with large thoracic wounds. Mean follow-up time was 16 months. Closure was obtained in the donor and recipient sites without the use of skin grafts or other more major procedures. Complications occurred in nine patients (36 percent), including dorsal wound dehiscence in five patients and seroma in three. All cases except one were treated by a conservative approach with a good result. No total flap loss was reported. All patients achieved a satisfactory thoracic reconstruction and adequate wound care. The V-Y latissimus dorsi musculocutaneous flap is a reliable technique for immediate locally advanced breast cancer reconstruction. The technique is advantageous because the V-Y design allows primary closure of the chest wound and donor defect. Success depends on patient selection, coordinated planning with the breast cancer surgeon, and careful intraoperative management.

    Mesenchymal stem cells (MSCs) represent an ideal source of autologous cell-based therapy for chronic wounds. Functional characteristics of MSCs may benefit wound healing by exerting their multi-regenerative potential. However, cell ageing resulting from chronic degenerative diseases or donor age could cause inevitable effects on the regenerative abilities of MSCs. A variety of studies have shown the relationship between MSC ageing and age-related dysfunction, but few associate these age-related impacts on MSCs with their ability of repairing chronic wounds, which are common in the elderly population. Here, we discuss the age-associated changes of MSCs and describe the potential impacts on MSC-based therapy for chronic wounds. Furthermore, critical evaluation of the current literatures is necessary for understanding the underlying mechanisms of MSC ageing and raising the corresponding concerns on considering their possible use for chronic wound repair. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Full Text Available Background: Infantile Hemangiomas (IH are the most common benign tumor of infancy, occurring in over 10% of newborns. While most IHs involute and never require intervention, some scalp IHs may cause severe cosmetic deformity and threaten tissue integrity that requires surgical excision. Case Description: We present our experience with two infants who presented with large scalp IH. After vascular imaging, the patients underwent surgical resection of the IH and primary wound closure with excellent cosmetic outcome. We detail the surgical management of these cases and review the relevant literature. Conclusion: In some cases the IHs leave behind fibro-fatty residuum causing contour deformity. Surgery is often required for very large lesions causing extensive anatomical and/or functional disruption. The goal of surgical intervention is to restore normal anatomic contour and shape while minimizing the size of the permanent scar.

    In recent conflicts, battlefield injuries consist largely of extensive soft injuries from blasts and high energy projectiles, including gunshot wounds. Repair of these large, traumatic wounds requires aggressive surgical treatment, including multiple surgical debridements to remove devitalised tissue and to reduce bacterial load. Identifying those patients with wound complications, such as infection and impaired healing, could greatly assist health care teams in providing the most appropriate and personalised care for combat casualties. Candidate technologies to enable this benefit include the fusion of imaging and optical spectroscopy to enable rapid identification of key markers. Hence, a novel system based on IR negative contrast imaging (NCI) is presented that employs an optical parametric oscillator (OPO) source comprising a periodically-poled LiNbO3 (PPLN) crystal. The crystal operates in the shortwave and midwave IR spectral regions (ca. 1.5 - 1.9 μm and 2.4 - 3.8 μm, respectively). Wavelength tuning is achieved by translating the crystal within the pump beam. System size and complexity are minimised by the use of single element detectors and the intracavity OPO design. Images are composed by raster scanning the monochromatic beam over the scene of interest; the reflection and/or absorption of the incident radiation by target materials and their surrounding environment provide a method for spatial location. Initial results using the NCI system to characterise wound biopsies are presented here.

    As long as a wound is infected, the healing process cannot begin. The indication for wound antiseptic is dependent on the interaction between the wound, the causative micro-organisms, and the host immune system. An uncritical colonisation is a condition whereby micro-organisms on a wound will proliferate, yet the immune system will not react excessively. Wound antiseptic is most often not necessary unless for epidemiologic reasons like colonisation with multi-resistant organisms. In most instances of a microbial contamination of the wound and colonisation, thorough cleaning will be sufficient. Bacterial counts above 105 to 106 cfu per gram tissue (critical colonisation) might decrease wound healing due to release of toxins, particularly in chronic wounds. Traumatic and heavily contaminated wounds therefore will require anti-infective measures, in particular wound antiseptic. In such situations, even a single application of an antiseptic compound will significantly reduce the number of pathogens, and hence, the risk of infection. If a wound infection is clinically manifest, local antiseptics and systemic antibiotics are therapeutically indicated. The prophylactic and therapeutic techniques for treatment of acute and chronic wounds (chemical antiseptics using xenobiotics or antibiotics, biological antiseptic applying maggots, medical honey or chitosan, physical antiseptic using water-filtered infrared A, UV, or electric current) mostly have been empirically developed without establishing a fundamental working hypothesis for their effectiveness. The most important aspect in controlling a wound infection and achieving healing of a wound is meticulous debridement of necrotic material. This is achieved by surgical, enzymatic or biological means e.g. using maggots. However, none of these methods (with some exception for maggots) is totally gentle to vital tissue and particularly chemical methods possess cytotoxicity effects.

    Full Text Available Management of perineal wounds can be very frustrating as these invariably get contaminated from the ano-genital tracts. Moreover, the apparent skin defect may be associated with a significant three dimensional dead space in the pelvic region. Such wounds are likely to become chronic and recalcitrant if appropriate wound management is not instituted in a timely manner. These wounds usually result after tumor excision, following trauma or as a result of infective pathologies like hideradenitis suppurativa or following thermal burns. Many options are available for management of perineal wounds and these have been discussed with illustrative case examples. A review of literature has been done for listing commonly instituted options for management of the wounds in perineum.

    The effects of multiple medications may impair or enhance wound healing. A review of the literature for drug side effects identified cell culture and case studies of angiotensin-converting enzyme inhibitors (ACEIs) impairing collagen deposition in cutaneous wounds; these medications have also been used to prevent or minimize keloid formation. A 71-year-old male patient presented with a venous leg ulcer (VLU), having incurred a crushing injury and fracture requiring surgical repair 16 years earlier. The patient's history was significant for obesity, smoking 1 cigar daily, hypertension, and lower extremity venous insufficiency; medications included amlodipine and lisinopril. The wound initially responded well to advanced wound products and compression, but wound healing subsequently stalled. A collagen-containing alginate dressing was added to the treatment regimen and the wound closed within 2 weeks. We postulate that lisinopril may have contributed to the observed delayed healing and targeted this potential impediment to wound healing with a readily available topical collagen-containing product resulting in a rapid wound closure after a significant delay in progress toward wound healing.

  9. Using portable negative pressure wound therapy devices in the home care setting

    2014-12-01

    Full Text Available Joshua R Burke, Rachael Morley, Mustafa Khanbhai Academic Surgery Unit, Education and Research Centre, University Hospital of South Manchester, Manchester, UK Abstract: Negative pressure wound therapy (NPWT is the continuous or intermittent application of subatmospheric pressure to the surface of a wound that improves the wound environment, accelerates healing, and reduces wound closure time. Since its first documented use, this technology has lent itself to a number of adaptations, most notably, the development of portable devices facilitating treatment in the home care setting. With advancing surgical standards, wound healing is an important rate-limiting factor in early patient discharge and often a major cost of inpatient treatment. The efficacy of NPWT in the home care setting has been investigated through rate of wound closure, time in care, and patient experience. Rate of wound closure is the most appropriate primary end point. Much can be gleaned from patient experience, but the future success of portable NPWT will be measured on time in care and therefore cost effectiveness. However, there is a lack of level 1a evidence demonstrating increased efficacy of portable over inpatient NPWT. The development of portable NPWT is an encouraging innovation in wound care technology, and extending the benefits to the home care setting is both possible and potentially more beneficial.

    Management of extravasation injuries over the dorsum of hand after administration of chemotherapeutic agents. To study the results of hypogastric flap reconstruction in chemotherapy extravasation wounds over dorsum of hand. Retrospective study. At our center over 3-years period, 32 patients were treated for chemotherapy extravasation wounds. Out of these 32 patients, seven had wound over dorsum of hand. There were five males and two females, and their mean age was 45 years (range, 19 - 64 years). These patients with wound over the dorsum of hand were treated with multiple debridements and hypogastric flap reconstruction. The mean interval between extravasation wound and surgical treatment was 6.28 days (range, 4 - 10). The mean size of extravasation wound defect was 14 × 8 (range, 12 × 7 to 18 × 8). Non-dominant hand was involved in six patients and dominant hand in one patient. In four patients, the hypogastric flap was supplemented with skin graft. The hypogastric flap settled well in all patients and enabled a good wound cover. Complete division of the flap and final insetting was done under local anesthesia after 3 weeks; this was followed by limb mobilization exercises. Contour difference over the dorsum of hand was present in all the cases. The range of movement of the hand was functionally restricted in one patient. No patient in current series developed wound infection. Hypogastric flap is a reliable flap to cover wound over dorsum of hand after extravasation of chemotherapeutic agents.

    Children represent a population at risk, because of their short size, their naivety and their attraction to animals. The face and hands are the most specific locations in young children. Wounds are often multiple. In more than half the cases, the child knows the animal, which are dogs and cats by frequency argument. The bite episode occurs mostly when the child is alone with the pet without direct supervision, while playing or stroking the animal. As in all bites, pediatric lesions are infectious, functional and aesthetic emergencies, but the goal of this work was primarily to make a point on principles of surgical management of animal bites in children, highlighting pediatric specificities. Animal bites require psychological, anesthetic and surgical treatment, adapted to the child, in a specialized structure. Hospitalization and general anesthesia are more frequent in children. Any suspicion of mistreatment (and/or abuse) should lead to the child's hospitalization, even if wounds do not justify monitoring in a surgical environment. Emergency surgery is essential to limit functional and aesthetic consequences. The healing capacities of the child and the frequent lack of co-morbidity allow a conservative surgical treatment with suture, repositioning skin flaps and controlled healing in the first place. Immobilization, drainage, and antibiotics will complete the surgery. The healing process, however, leads to a specific management during scar remodeling phase and growth. Psychological care of the child and parents should not be forgotten, and has to start at the same time as surgical treatment at in acute phase.

    There are many different forms of negative pressure wound therapy dressings and it is important to distinguish clearly between each type. They enable the treatment to be adapted to the shape and depth of the wound, its degree of exudation and the persistence of the fibrinous areas on the surface. The machine's traction capacity, measured in mm of mercury (Hg), must be controlled to establish the healing profile: the more powerful the machine and the more contact there is between the foam and the wound, the faster the formation of the granulation tissue. There are many different solutions which are implemented in accordance with the clinical assessment of the wound.

  18. Honey: A Biologic Wound Dressing.

    Molan, Peter; Rhodes, Tanya

    2015-06-01

    Honey has been used as a wound dressing for thousands of years, but only in more recent times has a scientific explanation become available for its effectiveness. It is now realized that honey is a biologic wound dressing with multiple bioactivities that work in concert to expedite the healing process. The physical properties of honey also expedite the healing process: its acidity increases the release of oxygen from hemoglobin thereby making the wound environment less favorable for the activity of destructive proteases, and the high osmolarity of honey draws fluid out of the wound bed to create an outflow of lymph as occurs with negative pressure wound therapy. Honey has a broad-spectrum antibacterial activity, but there is much variation in potency between different honeys. There are 2 types of antibacterial activity. In most honeys the activity is due to hydrogen peroxide, but much of this is inactivated by the enzyme catalase that is present in blood, serum, and wound tissues. In manuka honey, the activity is due to methylglyoxal which is not inactivated. The manuka honey used in wound-care products can withstand dilution with substantial amounts of wound exudate and still maintain enough activity to inhibit the growth of bacteria. There is good evidence for honey also having bioactivities that stimulate the immune response (thus promoting the growth of tissues for wound repair), suppress inflammation, and bring about rapid autolytic debridement. There is clinical evidence for these actions, and research is providing scientific explanations for them.

  19. SDF-1α mediates wound-promoted tumor growth in a syngeneic orthotopic mouse model of breast cancer.

    Directory of Open Access Journals (Sweden)

    Christina H Stuelten

    Full Text Available Increased growth of residual tumors in the proximity of acute surgical wounds has been reported; however, the mechanisms of wound-promoted tumor growth remain unknown. Here, we used a syngeneic, orthotopic mouse model of breast cancer to study mechanisms of wound-promoted tumor growth. Our results demonstrate that exposure of metastatic mouse breast cancer cells (4T1 to SDF-1α, which is increased in wound fluid, results in increased tumor growth. Both, wounding and exposure of 4T1 cells to SDF-1α not only increased tumor growth, but also tumor cell proliferation rate and stromal collagen deposition. Conversely, systemic inhibition of SDF-1α signaling with the small molecule AMD 3100 abolished the effect of wounding, and decreased cell proliferation, collagen deposition, and neoangiogenesis to the levels observed in control animals. Furthermore, using different mouse strains we could demonstrate that the effect of wounding on tumor growth and SDF-1α levels is host dependent and varies between mouse strains. Our results show that wound-promoted tumor growth is mediated by elevated SDF-1α levels and indicate that the effect of acute wounds on tumor growth depends on the predetermined wound response of the host background and its predetermined wound response.

    Full Text Available Cardiac injuries caused by knives and firearms are slightly increasing in our environment. We report the case of a 43-year-old male patient with a transmediastinal gunshot wound (TGSW and a through-and-through cardiac wound who was hemodynamically stable upon his admission. He had an entrance wound below the left clavicle, with no exit wound, and decreased breath sounds in the right hemithorax. Chest X-ray showed the bullet in the right hemithorax and large right hemothorax. The ultrasound revealed pericardial effusion, and a chest tube produced 1500 cc. of blood, but he remained hemodynamically stable. Considering these findings, a median sternotomy was carried out, the through-and-through cardiac wounds were suture-repaired, lung laceration was sutured, and a pacemaker was placed in the right ventricle. The patient had uneventful recovery and was discharged home on the twelfth postoperative day. The management and prognosis of these patients are determined by the hemodynamic situation upon arrival to the Emergency Department (ED, as well as a prompt surgical repair if needed. Patients with a TGSW have been divided into three groups according to the SBP: group I, with SBP >100 mmHg; group II, with SBP 60–100 mmHg; and group III, with SBP <60 mmHg. The diagnostic workup and management should be tailored accordingly, and several series have confirmed high chances of success with conservative management when these patients are hemodynamically stable.

    Full Text Available Cutaneous wound continues to cause significant morbidity and mortality in the setting of diseases such as diabetes and cardiovascular diseases. Despite advances in wound care management, there is still an unmet medical need exists for efficient therapy for cutaneous wound. Combined treatment of adrenomedullin (AM and its binding protein-1 (AMBP-1 is protective in various disease conditions. To examine the effect of the combination treatment of AM and AMBP-1 on cutaneous wound healing, full-thickness 2.0-cm diameter circular excision wounds were surgically created on the dorsum of rats, saline (vehicle or AM/AMBP-1 (96/320 μg kg BW was topically applied to the wound daily and wound size measured. At days 3, 7, and 14, skin samples were collected from the wound sites. AM/AMBP-1 treated group had significantly smaller wound surface area than the vehicle group over the 14-day time course. At day 3, AM/AMBP-1 promoted neutrophil infiltration (MPO, increased cytokine levels (IL-6 and TNF-α, angiogenesis (CD31, VEGF and TGFβ-1 and cell proliferation (Ki67. By day 7 and 14, AM/AMBP-1 treatment decreased MPO, followed by a rapid resolution of inflammation characterized by a decrease in cytokines. At the matured stage, AM/AMBP-1 treatment increased the alpha smooth muscle actin expression (mature blood vessels and Masson-Trichrome staining (collagen deposition along the granulation area, and increased MMP-9 and decreased MMP-2 mRNA expressions. TGFβ-1 mRNA levels in AM/AMBP-1 group were 5.3 times lower than those in the vehicle group. AM/AMBP-1 accelerated wound healing by promoting angiogenesis, collagen deposition and remodeling. Treatment also shortened the days to reach plateau for wound closure. Thus, AM/AMBP-1 may be further developed as a therapeutic for cutaneous wound healing.

    Small and moderate scalds in toddlers are still the most frequent thermal injuries the pediatric surgeons have to face today. Over the last years, surgical treatment of these patients has changed in many aspects. Due to new dressing materials and new surgical treatment strategies that are particularly suitable for children, today, far better functional and aesthetic long-term results are possible. While small and moderate thermal injuries can be treated in most European pediatric surgical departments, the severely burned child must be transferred to a specialized, ideally pediatric, burn center, where a well-trained multidisciplinary team under the leadership of a (ideally pediatric) burn surgeon cares for these highly demanding patients. In future, tissue engineered full thickness skin analogues will most likely play an important role, in pediatric burn as well as postburn reconstructive surgery.

  5. Surgical infection in art.

    The earliest images of medicine and surgery in Western art are from the late Middle Ages. Although often attractive, at that time they were illustrative and mirrored the text on how to diagnose or treat a specific condition. These drawings in medieval manuscripts represent management of abscesses, perianal infection and fistulas, amputation, and wound dressings. With the Renaissance, art in all its forms flourished, and surgeons were represented at work draining carbuncles, infected bursae, and mastoiditis; managing ulcers, scrofula, and skin infections; and performing amputations. Specific diagnosis can be made, such as streptococcal infection in the discarded leg of the miraculous transplantation performed by Saints Cosmas and Damian and in the works of Rembrandt van Rijn and Frederic Bazille. Evocations of cytokine activity are evident in works by Albrecht Dürer, Edvard Munch, and James Tissot. The iconography of society's view of a surgeon is apparent and often not complimentary. The surgeon's art is a visual art. Astute observation leads to early diagnosis and better results in surgical infection and the septic state. Learning to see what we look at enhances our appreciation of the world around us but, quite specifically, makes us better clinicians.

    To investigate the role of Pantoea agglomerans as an infectious agent that causes infection in a wound even after the wound was managed at the emergency department. A retrospective cohort study, reviewing the medical records of patients with traumatic wounds that were admitted to the emergency department from 2007-20 12 and had signs of wound infection for more than I 0 days after the wound was managed. Bacteriological results, clinical picture,and treatment results were obtained. Nine cases were identified. Pantoea agglomerans was detected in all cases. After 1-2 months of ineffective treatment, patients were hospitalised and surgical revisions of the wounds were performed.In all cases, small foreign bodies of plant origin were detected. After surgical revision, wounds were healed in 2-3 days. In cases of prolonged healing of post-traumatic wounds, the presence of foreign bodies of plant origin infected with Pantoea agglomerans should be taken into account. Removal of such foreign bodies leads to rapid healing of the wounds.

    Negative pressure wound therapy (NPWT) is widely used in the management of acute and chronic wounds. The purpose of this 8-week study was to evaluate outcomes of using a new canisterless, portable, single-use NPWT system in patients with wounds treated in a Canadian community healthcare setting. The device is designed to provide negative pressure at 80±20 mm Hg, 24 hours a day of continuous usage, for a maximum wear time of 7 days. Data on wound outcomes, including exudate levels, wound appearance, and wound area, were collected weekly by a Registered Nurse as part of routine practice. When treatment was discontinued, patients and nurses were asked to rate their satisfaction with the device. Data from patients who had used a conventional NPWT device to manage their wounds were retrospectively abstracted from their medical records. In the prospective study, conducted between October 2011 and July 2012, 326 patients (median age=61 years; range 17-91 years) with wounds of mixed etiology (53 pressure ulcers, 21 venous leg ulcers, 16 diabetic foot ulcers, and 15 traumatic and 221 surgical wounds) were treated for a maximum of 8 weeks with the portable NPWT device. The majority of patients (228 out of 326; 68%) achieved complete wound closure within 8 weeks of treatment. The Kaplan-Meier estimate of median time to healing of all wounds was 9 weeks. The majority of patients (318 patients, 97%) reported they were pleased or satisfied with the dressing performance. Nurses indicated satisfaction with the dressing performance for all but two patients (99%). The majority (89%) of patients managed with conventional NPWT (n=539) had an open surgical wound with moderate or high levels of exudate. Healing rates in the portable and conventional NPWT group were similar (10% to 11% per week). Portable, single-use NPWT has the potential to deliver good wound outcomes in community care settings and simplify the use of negative pressure for nurses and patients. Additional research is

    In vivo wound healing experiments remain the most predictive models for studying human wound healing, allowing an accurate representation of the complete wound healing environment including various cell types, environmental cues, and paracrine interactions. Small animals are economical, easy to maintain, and allow researchers to take advantage of the numerous transgenic strains that have been developed to investigate the specific mechanisms involved in wound healing and regeneration. Here we describe three reproducible murine wound healing models that recapitulate the human wound healing process.

    The wound healing process involves the reparative phases of inflammation, proliferation, and remodeling. Interrupting any of these phases may result in chronically unhealed wounds, amputation, or even patient death. Quantitative assessment of wound tissue ischemia, perfusion, and inflammation provides critical information for appropriate detection, staging, and treatment of chronic wounds. However, no method is available for noninvasive, simultaneous, and quantitative imaging of these tissue parameters. We integrated hyperspectral, laser speckle, and thermographic imaging modalities into a single setup for multimodal assessment of tissue oxygenation, perfusion, and inflammation characteristics. Advanced algorithms were developed for accurate reconstruction of wound oxygenation and appropriate co-registration between different imaging modalities. The multimodal wound imaging system was validated by an ongoing clinical trials approved by OSU IRB. In the clinical trial, a wound of 3mm in diameter was introduced on a healthy subject's lower extremity and the healing process was serially monitored by the multimodal imaging setup. Our experiments demonstrated the clinical usability of multimodal wound imaging.

    Victor W. Wong

    2013-01-01

    Full Text Available Chronic wounds represent a growing healthcare burden that particularly afflicts aged, diabetic, vasculopathic, and obese patients. Studies have shown that nonhealing wounds are characterized by dysregulated cytokine networks that impair blood vessel formation. Two distinct forms of neovascularization have been described: vasculogenesis (driven by bone-marrow-derived circulating endothelial progenitor cells and angiogenesis (local endothelial cell sprouting from existing vasculature. Researchers have traditionally focused on angiogenesis but defects in vasculogenesis are increasingly recognized to impact diseases including wound healing. A more comprehensive understanding of vasculogenic cytokine networks may facilitate the development of novel strategies to treat recalcitrant wounds. Further, the clinical success of endothelial progenitor cell-based therapies will depend not only on the delivery of the cells themselves but also on the appropriate cytokine milieu to promote tissue regeneration. This paper will highlight major cytokines involved in vasculogenesis within the context of cutaneous wound healing.

    Background is provided on biofilms, including their formation, tolerance mechanisms, structure, and morphology within the context of chronic wounds. The features of biofilms in chronic wounds are discussed in detail, as is the impact of biofilm on wound chronicity. Difficulties associated with the use of standard susceptibility tests (minimum inhibitory concentrations or MICs) to determine appropriate treatment regimens for, or develop new treatments for use in, chronic wounds are discussed, with alternate test methods specific to biofilms being recommended. Animal models appropriate for evaluating biofilm treatments are also described. Current and potential future therapies for treatment of biofilm-containing chronic wounds, including probiotic therapy, virulence attenuation, biofilm phenotype expression attenuation, immune response suppression, and aggressive debridement combined with antimicrobial dressings, are described.

    Background Wound infection following spinal instrumented surgery is a frequent complication.The optimal treatment of acute deep wound infection following spinal instrumentation fusion remains controversial because of variability in cohort identification,definition of an infection,and the instrument used to measure outcomes.This retrospective study evaluated the clinical curative effect for postoperative spinal infection after instrumented spine fusion with extensive debridement,or implant removal.Methods From January 2004 to October 2009,851 patients were identified who underwent surgical treatment of spinal diseases.The medical records of patients who developed infections were reviewed in detail.Results Of 851 patients,41 (4.9%) developed an infection.Thirty-three were acute,and eight were delayed.Acute infected cases were managed with antibiotic therapy,and aggressive debridement of the wound and soft tissues leaving all instrumentation in situ in all but one patient.The most common symptoms of acute infection included:posterior incisional drainage (26 of 33 patients),back pain (22 of 33 patients) and fever (13 of 33 patients).Among patients with delayed onset infection,five of eight patients had local pain,four of eight patients had incision drainage,and one patient had a prolonged period of intermittent fever.The most frequent causative organism for postoperative spinal infection following spine surgery is Staphylococcus aureus.Pseudarthrosis was noted in long-term follow-up in four of 41 patients.Conclusions We recommend irrigation and debridement,no instrumentation removal,and,if necessary,repeat debridement followed by delayed primary closure for the treatment of acute deep infection with instrumentation.

    Significant advances in veterinary diagnostic and surgical techniques have been made over the past several decades. Many of these advances, however, have not reached the field of marine mammal medicine. A number of limitations exist: risks of anesthesia, anatomical challenges, difficulties with wound closure, environmental constraints, equipment limitations, and perceived risks. Despite these limitations, surgical treatments have been successfully utilized in marine mammals. While surgery is performed in pinnipeds more frequently than in cetaceans, studies conducted in the 1960s and 1970s on dolphin sleep and hearing demonstrated that general anesthesia can be successfully induced in cetaceans. Since this pioneering work, a small number of successful surgeries have been performed in dolphins under both general anesthesia and heavy sedation. While these surgical procedures in pinnipeds and cetaceans have typically been limited to wound management, dentistry, ophthalmic procedures, fracture repair, and superficial biopsy, a number of abdominal surgeries have also been performed. Recently there have been pioneering successes in the application of minimally invasive surgery in marine mammals. Many of the anatomical challenges that almost prohibit traditional laparotomies in cetacean species and present challenges in pinnipeds can be overcome through the use of laparoscopic techniques. Due to the limited number of pinnipeds and cetaceans in captivity and, thus, the limited case load for veterinarians serving marine mammal species, it is vital for knowledge of surgical procedures to be shared among those in the field. This paper reviews case reports of surgical procedures, both traditional and laparoscopic, in pinnipeds and cetaceans. Limitations to performing surgical procedures in marine mammals are discussed and surgical case reports analyzed in an effort to determine challenges that must be overcome in order to make surgery a more feasible diagnostic and treatment

  4. Surgical Tips in Frozen Abdomen Management: Application of Coliseum Technique

    Directory of Open Access Journals (Sweden)

    Ioannis D. Kyriazanos

    2015-01-01

    Full Text Available Wound dehiscence is a serious postoperative complication, with an incidence of 0.5–3% after primary closure of a laparotomy incision, and represents an acute mechanical failure of wound healing. Relatively recently the concept of “intentional open abdomen” was described and both clinical entities share common pathophysiological and clinical pathways (“postoperative open abdominal wall”. Although early reconstruction is the target, a significant proportion of patients will develop adhesions between abdominal viscera and the anterolateral abdominal wall, a condition widely recognized as “frozen abdomen,” where delayed wound closure appears as the only realistic alternative. We report our experience with a patient who presented with frozen abdomen after wound dehiscence due to surgical site infection and application of the “Coliseum technique” for its definitive surgical management. This novel technique represents an innovative alternative to abdominal exploration, for cases of “malignant” frozen abdomen due to peritoneal carcinomatosis. Lifting the edges of the surgical wound upwards and suspending them under traction by threads from a retractor positioned above the abdomen facilitates approach to the peritoneal cavity, optimizes exposure of intra-abdominal organs, and prevents operative injury to the innervation and blood supply of abdominal wall musculature, a crucial step for subsequent hernia repair.

    Cervical spinal neurinomas are benign tumors that arise from nerve roots. Based on their location, these tumors can also take the form of a dumbbell-shaped mass. Treatment strategies for these tumors have raised several controversial issues such as appropriate surgical indications and selection of surgical approaches for cervical dumbbell-shaped spinal neurinomas. In this report, we review previous literature and retrospectively analyze cervical spinal neurinoma cases that have been treated at our hospital. Surgical indications and approaches based on tumor location and severity are discussed in detail. Thus, with advances in neuroimaging and neurophysiological monitoring, we conclude that appropriate surgical approaches and intraoperative surgical manipulations should be chosen on a case-by-case basis.

    2015-09-01

    A 48-year-old woman with antiphospholipid syndrome (APS) had multiple skin necrosis caused by massive bleeding and hematoma collection at the right lower leg, left thigh, and abdomen. During the first month, we did surgical debridement every 2 to 3 days with meticulous coagulation and applied negative pressure wound therapy (NPWT). Then as the base showed initial granulation, we changed the NPWT every 4 days. NPWT was used with lower pressure and cyclic mode (-40 to -75 mm Hg) to minimize trauma and to reduce the possibility of bleeding from the wounds. After 2 months of NPWT treatment, all the wounds eventually healed with secondary intension despite the patient's condition with diabetes, hemodialysis, anticoagulant use, and corticosteroid therapy. This report supports the idea that if accompanied by conservative debridement with meticulous bleeding control, application of NPWT in low pressures and close monitoring of the patient, NPWT is possible to use even in wounds of patients with risk for bleeding.

    2015-06-01

    Full Text Available OBJECTIVE: To determinate whether a surgical protocol with immediate extensive debridement, closed irrigation system and antibiotic therapy would be effective to achieve healing of deep wound infection without removing the instrumentation.METHODS: Prospective cohort study with 19 patients presenting degenerative spinal stenosis or degenerative spondylolisthesis, who developed infection after posterior lumbar arthrodesis. The diagnosis was confirmed by a microbial culture from subfascial lumbar fluid and/or blood. Patients were treated with a protocol of wound exploration, extensive flushing and debridement, placement of a closed irrigation system that was maintained for five days and intravenous antibiotics. The instrumentation system was not removed.RESULTS: Mean age was 59.31 (±13.17 years old and most patients were female (94.7%; 18/19. The mean period for the identification of the infection was 2 weeks and 57.9% underwent a single wound exploration. White blood count, erythrocyte sedimentation rate and C-reactive protein showed a significant decrease post-treatment when compared to pre-treatment values. A significant reduction of erythrocyte sedimentation rate and C-reactive protein was also observed at the final evaluation. No laboratory test was useful to predict the need for more than one debridement.CONCLUSION: Patients with wound infection after instrumentation can be treated without removal of the instrumentation through wound exploration, extensive flushing, debridement of necrotic tissue, closed irrigation system during 5 days and proper antibiotic therapy. The blood tests were not useful to predict surgical re-interventions.

    2016-12-01

    Full Text Available Background & Objective: The present study surveys the effects of propofol on cutaneous wound healing in rats. Materials & Methods: 36 adult female Strague-Dawely rats were divided into three groups randomly; in group one propofol (60 mg/kg and ketamine (40 mg/kg combination; in group two ketamine (50 mg/kg, and in group three propofol (100 mg/kg was injected intraperitoneally. Following routine surgical preparation, 1.5×1.5 cm wounds were created on the back of the rats. Wound size was evaluated daily and then the wound area was calculated by Digimizer software. Following euthanasia on day 21 after wounding, 1×1 cm skin samples were collected for histopathological evaluations and hydroxyproline content. Results: Wound size and hydroxyproline content showed no significant difference in propofol group compared to ketamine and propofol-ketamine groups. Fibroblast content and vascularity revealed no significant difference between groups. Inflammatory cell infiltration in ketamine group, collagen deposition in ketamine-propofol groups, and epithelial regeneration in propofol group were significantly higher in comparison with others. Conclusion: In conclusion, single use of propofol has no adverse effect on cutaneous wound healing in rats compared to ketamine, but evaluation of its positive effects on wound healing necessitates more detailed studies.

    To describe an apparent association between the use of ketorolac 0.5% (Acular; Allergan) for cystoid macular edema (CME) prophylaxis and impaired corneal wound healing in patients undergoing extracapsular cataract extraction (ECCE) with intraocular lens (IOL) implantation. A retrospective case series reviewing 7 eyes of 7 patients who underwent uncomplicated ECCE with IOL implantation and were treated postoperatively with ketorolac 0.5% 4 times daily as a prophylactic measure against CME. Patients were treated with ketorolac 0.5% 4 times a day for an average of 30 days (range, 20-44 days) after uncomplicated ECCE with IOL implantation. Two eyes developed postoperative endophthalmitis necessitating vitreous tap with intravitreal antibiotic injection; 1 eye went on to require pars plana vitrectomy with corneal wound resuturing. One eye developed corneal wound dehiscence that required wound resuturing in the operating room. One eye developed an inadvertent filtering bleb despite the lack of postoperative suture lysis. Three others were followed up closely postoperatively with slit-lamp evidence of impaired wound healing, manifested by wound avascularity and/or wound gape, and did not require surgical intervention. The use of nonsteroidal anti-inflammatory agents for prophylaxis of CME after cataract surgery is an evolving trend. This retrospective case series showed a possible link between the use of ketorolac 0.5% and impaired corneal wound healing, and caution is urged in the liberal use of this agent postoperatively after ECCE.

    The skin wound microenvironment can be divided into two main components that influence healing: the external wound microenvironment, which is outside the wound surface; and the internal wound microenvironment, underneath the surface, to which the cells within the wound are exposed. Treatment methods that directly alter the features of the external wound microenvironment indirectly affect the internal wound microenvironment due to the exchange between the two compartments. In this review, we focus on the effects of temperature, pressure (positive and negative), hydration, gases (oxygen and carbon dioxide), pH, and anti-microbial treatment on the wound. These factors are well described in the literature and can be modified with treatment methods available in the clinic. Understanding the roles of these factors in wound pathophysiology is of central importance in wound treatment. © 2015 by the Wound Healing Society.

    Fibrin biomatrices have been used for many years for hemostasis and sealing and are a well-established surgical tool. The objective of the present study was to compare two commercially available fibrin biomatrices regarding the effect of their thrombin concentration on keratinocytes and wound healing in vitro and in vivo. Keratinocytes showed significant differences in adhesion, viability, and morphology in the presence of the fibrin matrices in vitro. A high thrombin concentration (800-1,200 IU/mL) caused deteriorated cell compatibility. By using a thrombin inhibitor, those differences could be reversed. In a rat excisional wound healing model, we observed more rapid wound closure and less wound severity in wounds treated with a fibrin matrix containing a lower concentration of thrombin (4 IU/mL). Furthermore, fewer new functional vessels and a lower level of vascular endothelial growth factor were measured in wounds after 7 days treated with the matrix with higher thrombin concentration. These in vivo results may be partially explained by the in vitro biocompatibility data. Additionally, results show that low thrombin biomatrices were degraded faster than the high thrombin material. Hence, we conclude that the composition of fibrin biomatrices influences keratinocytes and therefore has an impact on wound healing.

To do the assessment, patients with partial thickness burn wounds with total body surface area nylon wound dressing or silver sulfadiazine cream. Efficacy of treatment, use of analgesics, number of wound dressing change, wound infection and final hospitalisation cost were evaluated. The study showed silver nylon wound dressing significantly reduced length of hospital stay, analgesic use, wound infection and inflammation compared with silver sulfadiazine.

    Corals routinely lose tissue due to causes ranging from predation to disease. Tissue healing and regeneration are fundamental to the normal functioning of corals, yet we know little about this process. We described the microscopic morphology of wound repair in Pocillopora damicornis. Tissue was removed by airbrushing fragments from three healthy colonies, and these were monitored daily at the gross and microscopic level for 40 days. Grossly, corals healed by Day 30, but repigmentation was not evident at the end of the study (40 d). On histology, from Day 8 onwards, tissues at the lesion site were microscopically indistinguishable from adjacent normal tissues with evidence of zooxanthellae in gastrodermis. Inflammation was not evident. P. damicornis manifested a unique mode of regeneration involving projections of cell-covered mesoglea from the surface body wall that anastomosed to form gastrovascular canals.

    Full Text Available Recently the vacuum therapy of wounds (Vacuum-assisted closure, VAC is traditionally used method of treatment of wound complications in patients with diabetes in the majority of surgical departments of relevant profile in Ukraine. Due to publications of Ukrainian authors including the popularization of this treatment method, its therapeutic effects and significant advantages as compared with the traditionally used method of treating wounds by dressing in a moist environment (Moist Wound Healing has led to a number of unresolved issues relating to the application VAC-therapy. One of those is the way of assessment of wound process course on a background of the VAC-therapy. One of the most accessible and easy means of diagnostics of wound healing course is the cytological smear of wounds. Despite the long-term use of cytological method of diagnosis of wounds, peculiarities of phase course of wound process in diabetic patients on the background of VAC-therapy remain poorly studied. As a result of our research it was determined that a statistically significant difference between the basic cytological indices in the vacuum group and conventional treatment are revealed by 9-10 days of treatment. A more favorable course of wound healing on the background of vacuum therapy of wounds was reflected in the reduction of neutrophils number from 186,2±10,13 in the first cytogram to 87,3±6,12 in the fourth, presence of fibroblasts on an average of 0.8 in the field of vision on 9-10 days of treatment, absence of a smear microflora print on 7-8 days of treatment. At the end of the treatment in the conventional treatment group degenerative-regenerative index was 0,65±0,37, in the vacuum group – 1,31±0,63.

    Objective:To explore the effect of Suyuping combined with semiconductor laser irradiation on the wound healing after anal fistula surgery.Methods:A total of 180 patients with anal fistula who were admitted in our hospital from October, 2013 to May, 2015 for surgery were included in the study and randomized into the treatment group and the control group with 90 cases in each group. The patients in the control group were given the conventional surgical debridement dressing, a time a day. On this basis, the patients in the treatment group were given Suyuping smearing on the wound sinus tract combined with semiconductor laser irradiation, a time a day for 10 min, continuous irradiation until wound healing. The postoperative wound swelling fading, wound surface secretion amount, and the clinical efficacy in the two groups were recorded.Results:The wound surface swelling degree and wound pain degree at each timing point after operation in the treatment group were significantly lower than those in the control group (P<0.05). The wound surface area at each timing point after operation in the treatment group was significantly lower than that in the control group (P<0.05). The wound surface secretion amount 6, 9, and 12 days after operation in the treatment group was significantly lower than that in the control group (P<0.05). The total effective rate in the treatment group was significantly higher than that in the control group (P<0.05). The average healing time in the treatment group was significantly faster than that in the control group (P<0.05). Conclusions: Suyuping combined with semiconductor laser irradiation in the treatment of patients after anal fistula can effectively improve the local blood and lymphatic circulation of wound surface, promote the growth of granulation tissues, and contribute the wound healing.

    There are a wide variety of dressing techniques and materials available for management of both acute wounds and chronic non-healing wounds. The primary objective in both the cases is to achieve a healed closed wound. However, in a chronic wound the dressing may be required for preparing the wound bed for further operative procedures such as skin grafting. An ideal dressing material should not only accelerate wound healing but also reduce loss of protein, electrolytes and fluid from the wound, and help to minimize pain and infection. The present dictum is to promote the concept of moist wound healing. This is in sharp contrast to the earlier practice of exposure method of wound management wherein the wound was allowed to dry. It can be quite a challenge for any physician to choose an appropriate dressing material when faced with a wound. Since wound care is undergoing a constant change and new products are being introduced into the market frequently, one needs to keep abreast of their effect on wound healing. This article emphasizes on the importance of assessment of the wound bed, the amount of drainage, depth of damage, presence of infection and location of wound. These characteristics will help any clinician decide on which product to use and where,in order to get optimal wound healing. However, there are no 'magical dressings'. Dressings are one important aspect that promotes wound healing apart from treating the underlying cause and other supportive measures like nutrition and systemic antibiotics need to be given equal attention.

    Aloe vera is a cactus-like perennial succulent belonging to the Liliaceae Family that is commonly grown in tropical climates. Animal studies have suggested that Aloe vera may help accelerate the wound healing process. To determine the effects of Aloe vera-derived products (for example dressings and topical gels) on the healing of acute wounds (for example lacerations, surgical incisions and burns) and chronic wounds (for example infected wounds, arterial and venous ulcers). We searched the Cochrane Wounds Group Specialised Register (9 September 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3), Ovid MEDLINE (2005 to August Week 5 2011), Ovid MEDLINE (In-Process & Other Non-Indexed Citations 8 September 2011), Ovid EMBASE (2007 to 2010 Week 35), Ovid AMED (1985 to September 2011) and EBSCO CINAHL (1982 to 9 September 2011). We did not apply date or language restrictions. We included all randomised controlled trials that evaluated the effectiveness of Aloe vera, aloe-derived products and a combination of Aloe vera and other dressings as a treatment for acute or chronic wounds. There was no restriction in terms of source, date of publication or language. An objective measure of wound healing (either proportion of completely healed wounds or time to complete healing) was the primary endpoint. Two review authors independently carried out trial selection, data extraction and risk of bias assessment, checked by a third review author. Seven trials were eligible for inclusion, comprising a total of 347 participants. Five trials in people with acute wounds evaluated the effects of Aloe vera on burns, haemorrhoidectomy patients and skin biopsies. Aloe vera mucilage did not increase burn healing compared with silver sulfadiazine (risk ratio (RR) 1.41, 95% confidence interval (CI) 0.70 to 2.85). A reduction in healing time with Aloe vera was noted after haemorrhoidectomy (RR 16.33 days, 95% CI 3.46 to 77.15) and there was

    Objective To investigate the clinical characteristics of invasive bum wound infection with sepsis in patients with major burns and to summarize the successful expenences in the treatment of such patients. Methods Eight patients with major bums, complicated by invesive bum wound infection and sepsis were consecutively admitted to our hospital from September 1997 to October 1998. Among them, 6 patients developed multiple organ dysfunction syndrome (MODS) and 2 developed septic shock. The plasma concentrations of IL-6,IL-8,TNFα and lypopolysaccharibe (LPS) were assayed before and after surgical intervention, as well as when the patient' s vital signs became stable. Results The patients' conditions usually deterieorated abruptly when extensive invasive bum wound infection emerged. While multi-microbial infection was usually found, Pseudomonas aeruginosa was the predominant bactena isolated from the subeschar tissue. The plasma concentrations of IL-6, IL-8, TNFα and LPS before surgical intervention wore significantly higher than those after surgical intervention (P<0.05).The lowest levels of the inflammatory mediators were abserved when the patients'conditions became stable,and the values were significantly lower than those before surgical intervention ( P<0.001). Conclusion Since the main cause of burn wound sepsis is the presence of a large area of infected bum wound, they should be excised and covered as early as possible. LPS and pro-inflammatory mediators play an important role in the pathogenesis of burn sepsis. Athough favorable results should be attributed to compmhessive treatment, we believe that early, aggressive and thorough surgical excision of infected burn wounds, followed by sound and complete coverage of the area, play a crucial role.

    A fundamental feature of multicellular organisms is their ability to self-repair wounds through the movement of epithelial cells into the damaged area. This collective cellular movement is commonly attributed to a combination of cell crawling and `purse-string’ contraction of a supracellular actomyosin ring. Here we show by direct experimental measurement that these two mechanisms are insufficient to explain force patterns observed during wound closure. At early stages of the process, leading actin protrusions generate traction forces that point away from the wound, showing that wound closure is initially driven by cell crawling. At later stages, we observed unanticipated patterns of traction forces pointing towards the wound. Such patterns have strong force components that are both radial and tangential to the wound. We show that these force components arise from tensions transmitted by a heterogeneous actomyosin ring to the underlying substrate through focal adhesions. The structural and mechanical organization reported here provides cells with a mechanism to close the wound by cooperatively compressing the underlying substrate.

  4. Evolving issues in the prevention of surgical site infections.

    Surgical site infection is one of the more common causes of post-operative morbidity. Such infections contribute to prolonged recovery, delayed discharge and increasing costs to both patients and the health service. In the current climate increased emphasis is being placed on minimising the risks of acquiring or transmitting these nosocomial infections. This article reviews the current literature obtained from a Pubmed database search in relation to three specific aspects of surgical site infection: compliance with prophylactic antibiotics, post-discharge surveillance and novel methods for preventing surgical site infections. These topics represent areas where many institutions will find room for improvement in the prevention of surgical site infections. Tight adherence to prophylactic antibiotic guidelines, close followup of surgical wounds during and after hospital discharge, and attention to oxygenation status and the body temperature of patients may all prove to be useful adjuncts in significantly decreasing surgical site infections.

  5. The mobilization and recruitment of c-kit+ cells contribute to wound healing after surgery.

    Directory of Open Access Journals (Sweden)

    Yoshihiro Takemoto

    Full Text Available Delayed wound healing is a serious clinical problem in patients after surgery. A recent study has demonstrated that bone marrow-derived c-kit-positive (c-kit(+ cells play important roles in repairing and regenerating various tissues and organs. To examine the hypothesis that surgical injury induces the mobilization and recruitment of c-kit+ cells to accelerate wound healing. Mice were subjected to a left pneumonectomy. The mobilization of c-kit+ cells was monitored after surgery. Using green fluorescent protein (GFP(+ bone marrow-transplanted chimera mice, we investigated further whether the mobilized c-kit+ cells were recruited to effect wound healing in a skin puncture model. The group with left pneumonectomies increased the c-kit(+ and CD34(+ stem cells in peripheral blood 24 h after surgery. At 3 days after surgery, the skin wound size was observed to be significantly smaller, and the number of bone marrow-derived GFP(+ cells and GFP(+/c-kit+ cells in the wound tissue was significantly greater in mice that had received pneumonectomies, as compared with those that had received a sham operation. Furthermore, some of these GFP(+ cells were positively expressed specific markers of macrophages (F4/80, endothelial cells (CD31, and myofibroblasts (αSMA. The administration of AMD3100, an antagonist of a stromal-cell derived factor (SDF-1/CXCR4 signaling pathway, reduced the number of GFP(+ cells in wound tissue and completely negated the accelerated wound healing. Surgical injury induces the mobilization and recruitment of c-kit+ cells to contribute to wound healing. Regulating c-kit+ cells may provide a new approach that accelerates wound healing after surgery.

    Under analysis were results of surgical treatment of 256 patients with abscessed and phlegmonous acute lactation mastitis. Radical primary surgical treatment of the purulent cavities allowed prevention of further progression of the inflammation in the mammary gland. The use of the low frequency ultrasound for treatment of the wound allowed to quicker arrest the acute inflammatory process in the tissues of the mammary gland surrounding the purulent cavity. In cases with diffuse purulent acute lactation mastitis it is necessary to take into attention the tension of the suture threads when fulfilling the secondary surgical treatment of the wound and putting in the running secondary early suture.

    Objective. To discuss the causes and treatments of wound infections after scoliosis surgery. Methods. Nine hundred and twenty-four cases of scoliosis were reviewed, and the clinical data of 15 cases of postoperative infection were analysed retrospectively. Results. All 15 cases underwent spinal posterior fusion with autologous bone graft using instrumentations. Seven were diagnosed as early infection, and 8 were delayed infection. Radical debridement was performed in all 15 cases. The duration of antibiotics administration was 10 to 34 days with continuous closed irrigation for 2~ 4 weeks and primary closure for the wounds. All patients were followed up for an average of 3.5 years (2 to 7.5 years) with good outcomes and no recurrence. Conclusion. Wound infection following surgical correction of scoliosis primarily results from intraoperative seeding, although host-related and operation-related factors may contribute to its development. Once the infections are diagnosed, good results can be achieved by prompt surgical debridement, irrigation and reasonably administered antibiotics. Removal of hardware may be necessary in deep infections.

    2016-01-01

    Despite diverse methods being applied to induce wound healing, many wounds remain recalcitrant to all treatments. Photobiomodulation involves inducing wound healing by illuminating wounds with light emitting diodes or lasers. While used on different animal models, in vitro, and clinically, wound healing is induced by many different wavelengths and powers with no optimal set of parameters yet being identified. While data suggest that simultaneous multiple wavelength illumination is more efficacious than single wavelengths, the optimal single and multiple wavelengths must be better defined to induce more reliable and extensive healing of different wound types. This review focuses on studies in which specific wavelengths induce wound healing and on their mechanisms of action.

    Wound care is an important step in promoting wound healing, but it may cause wound care pain. This article aims to explore factors influencing wound care pain and the effectiveness of various interventions to alleviate it. Five major factors that influence wound care pain include inappropriate dressing change techniques, inflammation response, emotion, cognition, and social-cultural factors. Nurses should apply appropriate dressings and dressing change techniques to relieve wound care pain. Music therapy and aromatherapy can alleviate wound pain after dressing change. But distraction techniques should be used in conjunction with consideration of the needs of the individual subject.

    1989-10-01

    This study examined the potential influence of platelet-derived growth factor-BB homodimers (PDGF-BB) on surgical incisions in irradiated animals with depressed wound healing. Rats were irradiated with either 800 rads total body or 2,500 rads surface irradiation. Parallel dorsal skin incisions were made 2 days later, and PDGF-BB was applied topically a single time to one of two incisions. In total body-irradiated rats, bone marrow-derived elements were severely depressed, wound macrophages were virtually eliminated, and PDGF-BB treatment was ineffective. However, in surface-irradiated rats, PDGF-BB treatment recruited macrophages into wounds and partially reversed impaired healing on day 7 (p less than 0.005) and day 12 (p less than 0.001). PDGF-BB-treated wounds were 50 percent stronger than the paired control wounds. The results suggest PDGF requires bone marrow-derived cells, likely wound macrophages, for activity and that it may be useful as a topical agent in postirradiation surgical incisions.

    2008-09-01

    The depth of a burn wound and/or its healing potential are the most important determinants of the therapeutic management and of the residual morbidity or scarring. Traditionally, burn surgeons divide burns into superficial which heal by rapid re-epithelialization with minimal scarring and deep burns requiring surgical therapy. Clinical assessment remains the most frequent technique to measure the depth of a burn wound although this has been shown to be accurate in only 60-75% of the cases, even when carried out by an experienced burn surgeon. In this article we review all current modalities useful to provide an objective assessment of the burn wound depth, from simple clinical evaluation to biopsy and histology and to various perfusion measurement techniques such as thermography, vital dyes, video angiography, video microscopy, and laser Doppler techniques. The different needs according to the different diagnostic situations are considered. It is concluded that for the initial emergency assessment, the use of telemetry and simple burn photographs are the best option, that for research purposes a wide range of different techniques can be used but that, most importantly, for the actual treatment decisions, laser Doppler imaging is the only technique that has been shown to accurately predict wound outcome with a large weight of evidence. Moreover this technique has been approved for burn depth assessment by regulatory bodies including the FDA.

    2008-04-01

    Gunshot wounds to the kidney occur with different regional incidence. They are commonly combined with thoracic and abdominal injuries. Gunshot wounds may be caused by low-velocity or high-velocity bullets. The latter are usually used with military weapons and cause a higher degree of tissue damage. The therapeutic management of renal gunshot wounds has changed in recent decades resulting in more organ-preserving strategies. An imperative indication for surgical exploration of the kidney is critical renal bleeding with symptoms of hypovolaemic shock. We report the case of a 23-year-old male admitted to the hospital with combined gunshot wounds from a small-bore weapon with damage of the liver, stomach and the left kidney. There were no signs of thoracic injuries. The patient underwent transabdominal exploration with treatment of the liver and stomach lesions, removal of the bullet and preservation of the left kidney. A percutaneous nephrostomy and drainage of the retroperitoneal region were inserted; antibiotic prophylaxis was given. A 4-week postoperative intravenous pyelogram showed complete integrity of the upper left tract and good renal function.

    Full Text Available Hyperbaric oxygen therapy (HBOT is the use of 100% oxygen at pressures greater than atmospheric pressure. Today several approved applications and indications exist for HBOT. HBOT has been successfully used as adjunctive therapy for wound healing. Non-healing wounds such as diabetic and vascular insufficiency ulcers have been one major area of study for hyperbaric physicians where use of HBOT as an adjunct has been approved for use by way of various studies and trials. HBOT is also indicated for infected wounds like clostridial myonecrosis, necrotising soft tissue infections, Fournier′s gangrene, as also for traumatic wounds, crush injury, compartment syndrome, compromised skin grafts and flaps and thermal burns. Another major area of application of HBOT is radiation-induced wounds, specifically osteoradionecrosis of mandible, radiation cystitis and radiation proctitis. With the increase in availability of chambers across the country, and with increasing number of studies proving the benefits of adjunctive use for various kinds of wounds and other indications, HBOT should be considered in these situations as an essential part of the overall management strategy for the treating surgeon.

    Purpose: X-ray findings are described, which are typical for injuries due to conventional weapons. It is intended to demonstrate that radiographs can show findings characteristic for weapons. Material and method: The radiograms have been collected in Vietnam, Croatia, Serbia, Bosnia, Chad, Iran, Afghanistan, USA, Great Britain, France, Israel, Palestine, and Germany. Results: Radiograms of injuries due to hand grenades show their content (globes) and cover fragments. The globes are localized regionally in the victim's body. Survivors of cluster bombs show singular or few globes; having been hit by many globes would have been lethal. Shotguns produce characteristic distributions of the pallets and depth of penetration different from those of hand grenades and cluster bombs; cover fragments are lacking. Gunshot wounds (GSW) can be differentiated in those to low velocity bullets, high velocity projectiles, and projectiles, which disintegrate on impact. The radiogram furnishes the information about a dangerous shock and helps to recognize the weapon. Radiograms of victims of explosion show fragments and injuries due to the blast, information valid for therapy planning and prognosis. The radiogram shows details which can be used in therapy, forensic medicine and in war propaganda - examples could be findings typical for cluster bombs and for dumdum bullets; it shows the cruelty of the employment of weapons against humans and the conflict between the goal of medical care and those of military actions. Conclusion: Radiographs may show, which weapon has been employed; they can be read as war reports.

    Full Text Available Background/Aim. Suture materials play an important role in healing, enabling reconstruction and reassembly of tissue separated by the surgical procedure or trauma, and at the same time facilitating and promoting healing and hemostasis. Suture materials are used daily in oral surgery, and are considered to be substances most commonly implanted in human body. The aim of this clinical study was to examine the speed of wound healing and complications incidence, after the use of three different absorbable synthetic suture materials in oral surgery (catgut, Dexon and Vicryl rapide, and to ascertain which one is the most suitable for oral surgery. Methods. The study was conducted on 96 patients undergoing root resection or surgical extraction of third molars. Each of the suture materials (catgut, Dexon and Vicryl rapide was used for 8 root resections and 8 surgical third molar extractions in the maxilla, as well as in the mandible (a total of 32 surgical interventions for each suture material. Results. The faster wound healing was obtained with Vicryl rapide compared to other two suturing material tested. There was no significant difference regarding the presence of local reaction in all the three groups of patients on the 21st postoperative day. Conclusion. The results of our clinical study point out that Vycrilrapid contributes more than catgut or Dexon to faster healing of human wounds, with fewer incidences of wound dehiscence and milder local reactions.

    Chronic wounds are an increasing problem in our ageing population and can arise in many different ways. Over the past decades it has become evident that sufficient oxygen supply is an essential factor of appropriate wound healing. Sustained oxygen deficit has a detrimental impact on wound healing, especially for patients with chronic wounds. This has been proven for wounds associated with peripheral arterial occlusive disease (PAOD) and diabetic foot ulcers (particularly in combination with PAOD). However, this is still under debate for other primary diseases. In the past few years several different new therapeutic approaches for topical oxygen therapies have been developed to support wound healing. These tend to fall into one of four categories: (1) delivery of pure oxygen either under pressurised or (2) ambient condition, (3) chemical release of oxygen via an enzymatic reaction or (4) increase of oxygen by facilitated diffusion using oxygen binding and releasing molecules. In this review article, the available therapeutic topical oxygen-delivering approaches and their impact on wound healing are presented and critically discussed. A summary of clinical data, daily treatment recommendations and practicability is provided. J.

    Summary Water jets have been used in many areas of surgery. Recently a new surgical debridement device was launched onto the market - VersajetTM. VersajetTM is a unique hydrosurgical device that uses a precise jet of water to simultaneously hold, cut, and remove devitalized or necrotic tissue. This paper describes our experience with ten patients comparing Weck knives with the newly designed hydrosurgical device when debriding burn wounds. The patients' age ranged from 27 to 60 yr (average, 37.8 yr) and the burn wounds treated were between 3 and 7% total body surface area, involving the face, abdomen, and limbs. The hydrosurgical system is a very useful tool for irregular and complex burn wound debridement. This paper represents the first written clinical experience utilizing hydrosurgery in the burn wound management in an Eastern country. PMID:21991073

  13. Cushing and the treatment of brain wounds during World War I.

    2011-06-01

    Harvey Cushing, perhaps the most important founder of American neurosurgery, was an Army neurosurgeon in France from 1917 to 1918. Over a 3-month period in 1917 he and his team operated on 133 soldiers with a brain wound. The operative mortality rate for their last 45 patients was 29%, considerably lower than the usual postoperative mortality rate of approximately 50% for those with a brain wound. This accomplishment was lauded at the time and eventually, for some, it was Cushing who was responsible for lowering the postoperative mortality rate of brain wounds during World War I. As the decades passed he was eventually credited as the "originator of brain wound care." This report shows that these attributions are misplaced. Cushing merely followed the enlightened surgical precepts of the time developed by Continental (European) surgeons. It also examines Cushing's writings to ascertain how these misperceptions concerning his originality might have been generated.

    Although the extraordinary agent wound is not common, the difficulties of its diagnosis, treatment, and the high medical risk as well as the indeterminacy of its prognosis bring great challenges to the clinicians. It is mainly attributed to the complexities of extraordinary agent wounds and the deficiency in the assessment technic of wound. Therefore, it is necessary and important to establish a precise assessment method to benefit the surgical planning, pre-estimation of peri-operative risk, and the doctor-patient communication. Based on the relative scientific research and our recent clinical research data, we bring forth our opinions on the current status and the development trend of the assessment of extraordinary agent wounds in this article.

    The aims of this study were as follows: first to quantify and review the types of surgical procedures performed by military surgeons assigned to a Forward Surgical Team (FST) providing medical support to the population (MSP) in the Ivory Coast (IC), and second to analyze how this MSP was achieved. Between 2002 and 2012, all of the local nationals operated on by the different FSTs deployed in the IC were included in the study. The surgical activity was analyzed and divided into surgical specialties, war wounds, nonwar emergency trauma, nontrauma emergencies, and elective surgery. Demographics, circumstances of health care management, wounded organs, and types of surgical procedures were described. Over this period, surgeons operated on 2,315 patients and performed 2,556 procedures. Elective surgery accounted for 78.7% of the surgical activity, nontrauma emergencies accounted for 12.7%, nonwar emergency trauma accounted for 8%, and war wounds accounted for 0.6%. The main surgical activities were visceral (43.8%) and orthopedic (including soft tissues) surgeries (38.5%). The FSTs contributed widely to MSP in the IC. This MSP required limited resources, standardization of the procedures and specific skills beyond the original surgical specialties of military surgeons to fulfill the needs of the local population.

    Breast cancer, skin cancer, and head and neck cancer often develops a hemorrhagic malignant wound. Bleeding from the tumor impairs patients' quality of life and can be life threatening, while surgical or electrical hemostasis is often unsuccessful because of the tumor's friability. We performed a chemical hemostatic treatment for breast cancer hemorrhage with zinc chloride paste (Mohs' paste), which is usually applied as a fixative in micrographic surgery for cutaneous neoplasms. Five patients with bleeding from breast cancer under various circumstances were treated with this technique in 2008. The method was successful on first application for all five patients, and hemostasis was maintained long term. This simple technique is effective for bleeding from malignant wounds and should be learned by health professionals performing cancer care.

    Mac-1 (CD11b/CD18) is a macrophage receptor that plays several critical roles in macrophage recruitment and activation. Because macrophages are essential for proper wound healing, the impact of Mac-1 deficiency on wound healing is of significant interest. Prior studies have shown that Mac-1(-/-) mice exhibit deficits in healing, including delayed wound closure in scalp and ear wounds. This study examined whether Mac-1 deficiency influences wound healing in small excisional and incisional skin wounds. Three millimeter diameter full thickness excisional wounds and incisional wounds were prepared on the dorsal skin of Mac-1 deficient (Mac-1(-/-) ) and wild type (WT) mice, and wound healing outcomes were examined. Mac-1 deficient mice exhibited a normal rate of wound closure, generally normal levels of total collagen, and nearly normal synthesis and distribution of collagens I and III. In incisional wounds, wound breaking strength was similar for Mac-1(-/-) and WT mice. Wounds of Mac-1 deficient mice displayed normal total macrophage content, although macrophage phenotype markers were skewed as compared to WT. Interestingly, amounts of TGF-β1 and its downstream signaling molecules, SMAD2 and SMAD3, were significantly decreased in the wounds of Mac-1 deficient mice compared to WT. The results suggest that Mac-1 deficiency has little impact on the healing of small excisional and incisional wounds. Moreover, the findings demonstrate that the effect of single genetic deficiencies on wound healing may markedly differ among wound models. These conclusions have implications for the interpretation of the many prior studies that utilize a single model system to examine wound healing outcomes in genetically deficient mice. © 2017 by the Wound Healing Society.

    Risk-adjusted rates of surgical site infections (SSI) are used as a quality metric to facilitate improvement within a hospital system and allow comparison across institutions. The NSQIP-Pediatric, among others, uses surgical wound classification as a variable in models designed to predict risk-adjusted postoperative morbidity, including SSI rates. The purpose of this study was to measure the level of agreement in wound classification assignment among 3 providers: surgeons, operating room (OR) nurses, and NSQIP surgical clinical reviewers (SCR). An analysis was performed of pediatric general surgery operations from 2010 to 2011. Wound classification was assigned at the time of operation by the OR nurse and surgeon, and by the NSQIP SCR postoperatively, according to NSQIP methodology. Disagreement was defined as any discrepancy in classification among the 3 providers, and the level of agreement was determined using the kappa statistic. For the 374 procedures reviewed, there was an overall disagreement of 48% among all providers, kappa 0.48 (95% CI 0.43 to 0.53). When comparing wound classification by surgeon and NSQIP SCR, 23% of cases were in disagreement, kappa 0.74 (95% CI 0.68 to 0.78). Disagreement between OR nurse and either surgeon or NSQIP SCR was higher: 38%, kappa 0.45 (95% CI 0.38 to 0.53) and 40%, kappa 0.44 (95% CI 0.37 to 0.51). Fundoplication, appendectomy, and cholecystectomy demonstrated the highest overall disagreement (73%, 71%, and 60%, respectively). There is significant variation in assigning surgical wound classification among health care providers. For future SSI comparative analyses, it will be critical to improve uniformity and understanding of wound class assignment among providers and institutions.
