    Zahir Hussain


    Full Text Available BACKGROUND Abdominal wound dehiscence is a preventable complication, but is still seen. When present, it poses problem in the management of the case, increases the morbidity and mortality of the patient. The present study is a prospective study done from January 2010-May 2016 with an objective to find out the incidence of wound dehiscence, the most common pathologies associated with dehiscence and to find out the statistical significance of the difference risk factors causing wound dehiscence and to evaluate the role of tension sutures in prevention of wound dehiscence. MATERIALS AND METHODS 291 major laparotomies were followed from January 2010-September 2016. There were 21 cases of dehiscence and from the remaining 270 cases, 58 patients were chosen as controls who underwent the same procedure, but without dehiscence. 15 factors were analysed and compared between the dehiscence and control groups. RESULTS The incidence was found to be 7.2%. Peritonitis was the most common pathology. The significant factors were age more than 50, wound infection. Tension suture application has shown to reduce the incidence of wound dehiscence. CONCLUSIONS  Intra-abdominal sepsis (peritonitis increases the incidence of wound dehiscence.  Age >50, Uraemic, Jaundiced, Obesity, Malnutrition increases the incidence of wound dehiscence.  Wound infection was a highly significant factor having 8 times more risk of dehiscence.

  2. The tip of the iceberg: Post caesarean wound dehiscence presenting as abdominal wound sepsis

    Kaundinya Kiran Bharatam


    Conclusion: Uterine scar dehiscence with infection requires high index of suspicion as rare cause for post partum localized/generalized peritonitis with sepsis. Severe abdominal wound infection after caesarean section may be associated with uterine wound dehiscence, which poses a grave risk to the mother in a future pregnancy.

    Asukai, Kei; Kashiwazaki, Masaki; Koizumi, Kaori; Nobunaga, Toshikatsu; Yano, Hiroshi


    Negative pressure wound therapy (NPWT) is an effective treatment for various non-healing wounds, and V.A.C.(®) Therapy was the first-approved NPWT device by the Japanese government in 2009. We report the case of a 19-week pregnant patient where V.A.C.(®) Therapy was applied to her dehisced laparotomy wound with satisfactory results. The patient was a 30-year-old female who was referred to our hospital from her previous doctor because of the presence of an ovarian cyst on the left ovary. The patient presented at 14 weeks into her pregnancy, and surgery was considered because of no reduction in the size of the cyst. An oophorocystectomy was performed, and then the surgical incision was re-opened at postoperative day (POD) 10 due to a surgical site infection. V.A.C.(®) Therapy was initiated on POD 26 (20 weeks of pregnancy) and continued for 28 days. After 28 days of V.A.C.(®) Therapy (POD 54), the wound was sutured for complete closure. The foetus did not experience any adverse affects from the surgery and, subsequently, normal vaginal delivery was achieved. This case is the first report of the use of V.A.C.(®) Therapy over a dehisced abdominal wound on a pregnant patient in our country.




    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.

    Spontaneous wound separation may be developed even months after suture removal especially in the context of long-term corticosteroid therapy. A 68-yearold Caucasian woman presented to our cornea clinic with spontaneous wound dehiscence after her third penetrating keratoplasty(PKP) which was performed three years ago. An Ahmed glaucoma valve(New World Medical, Ranchos Cucamonga, CA) was inserted ten months after the third PKP, which successfully controlled intraocular pressure(IOP). At the examination, the last sutures were removed eight months ago and she was using flourometholone 0.1%(Sina Darou, Tehran, Iran)with a dose of once a day. There was one quadrant of wound dehiscence from 8 to 11 o`clock associated with anterior wound gape and severe corneal edema.Resuturing was performed for the patient. At the one month examination, the corneal edema was resolved and best corrected visual acuity was 20/200 mainly due to previous glaucomatous optic neuropathy. Caution about the prolonged use of corticosteroids is necessary. Topical immunosuppressives could be a promising choice in this field.

  7. Episiotomy and obstetric perineal wound dehiscence: beyond soreness.

    Kamel, A; Khaled, M


    Postpartum episiotomy dehiscence is a rare complication of vaginal delivery. Infection rates in episiotomy wounds are surprisingly low; however, it remains the most common cause of wound dehiscence, which may lead to major physical, psychological and social problems if left untreated. Most dehisced perineal wounds are left to heal naturally by secondary intention. This approach often results in a protracted period of significant morbidity for women. There is emerging evidence that early re-suturing closure of broken-down perineal wounds may have a better outcome, but randomised controlled trials are needed to yield evidence-based guidance for this management approach.

  8. Traumatic Wound Dehiscence following Corneal Transplantation

    Mohammad-Reza Jafarinasab


    Full Text Available Purpose: To investigate the incidence, mechanisms, characteristics, and visual outcomes of traumatic wound dehiscence following keratoplasty. Methods: Medical records of 32 consecutive patients with traumatic globe rupture following keratoplasty who had been treated at our center from 2001 to 2009 were retrospectively reviewed. Results: The study population consisted of 32 eyes of 32 patients including 25 men and 7 women with history of corneal transplantation who had sustained eye trauma leading to globe rupture. Mean patient age was 38.1 (range, 8 to 87 years and median interval between keratoplasty and the traumatic event was 9 months (range, 30 days to 20 years. Associated anterior segment findings included iris prolapse in 71.9%, lens extrusion in 34.4%, and hyphema in 40.6% of eyes. Posterior segment complications included vitreous prolapse (56%, vitreous hemorrhage (28% and retinal detachment (18%. Eyes which had undergone deep anterior lamellar keratoplasty (DALK; 5 cases, 15.6% tended to have less severe presentation and better final visual acuity. There was no correlation between the time interval from keratoplasty to the traumatic event, and final visual outcomes. Conclusion: The host-graft interface demonstrates decreased stability long after surgery and the visual prognosis of traumatic wound dehiscence is poor in many cases. An intact Descemet′s membrane in DALK may mitigate the severity of ocular injuries, but even in these cases, the visual outcome of globe rupture is not good and prevention of ocular trauma should be emphasized to all patients undergoing any kind of keratoplasty.

  9. Traumatic wound dehiscence after corneal keratoplasty

    Patrick Frensel Tzelikis


    Full Text Available ABSTRACTPurpose:To assess patient characteristics, risk factors, outcomes, and the treatment of wound dehiscence (WD in patients after corneal keratoplasty.Methods:Retrospective chart review of 11 eyes of 11 patients with corneal grafts who underwent repair of WD from January 1, 2004 to December 31, 2012 at Hospital Oftalmologico de Brasilia.Results:Eight (72.7% patients were men and three were women. Six (54.5% patients had deep anterior lamellar keratoplasty (DALK and 5 had penetrating keratoplasty. The mean age at trauma was 31.1 years. The mean time from corneal keratoplasty to WD was 12.82 months (range, 3-33 months. The mean best-corrected visual acuity of patients before trauma was 20/60 (0.48 logMAR and after final treatment was 20/160 (0.90 logMAR (P=0.15. In one case, visual acuity decreased to no light perception because of retinal detachment and phthisis bulbi. Accidental blunt trauma and fall were the most common causes of WD.Conclusion:Patients who undergo corneal keratoplasty have a life-long risk of WD. The full-thickness rupture at the graft-host junction in our study suggests that the junction remains vulnerable, even following DALK, and can rupture with trauma. In our series, depending upon the severity of the trauma, postkeratoplastic WD can be associated with a good visual prognosis.

    Aydin Nadir


    Full Text Available OBJECTIVES: We described the treatment of dehiscence of thoracotomy incisions in patients who underwent thoracic surgery in the present study. METHODS: Twenty-four patients with either partial or complete dehiscence of their thoracotomy incisions were included in the study from 2005 to 2010. The patients were evaluated regarding their age, sex, indication for thoracotomy, and surgical approaches. We also described our method of re-closure. RESULTS: The male/female ratio was 17/7. The youngest and oldest patients were 15 and 75 years old, respectively, and the mean age was 43 years. Among the indications for thoracotomy, empyema was the most common reason (determined in eight [33%] patients, followed by vertebral surgery (determined in six [25%] patients. Bacterial growth was detected in the wound site cultures from 13 (54% patients. For the patients with dehiscence of their thoracotomy incisions, an en block approximation technique with debridement was performed under general or local anesthesia in 16 (66% and eight (33% of the cases, respectively. Three patients exhibited an open thorax with dehiscence of the thoracotomy incision. Thoracoplasty was required in two patients. Using this method, successful closure was obtained in 91.7% (n = 22 of the patients with dehiscence of their thoracotomy incisions. CONCLUSION: Dehiscence of the thoracotomy incision is an important complication that causes concern in patients and their thoracic surgeons and strongly affects the success of the surgery. An en block approximation technique with significant debridement that enables removal of the necrotic tissues from the wound site can successfully be applied to patients with dehiscence of their thoracotomy incisions.

  11. Wound dehiscence: is still a problem in the 21th century: a retrospective study

    Giafis Konstantinos


    Full Text Available Abstract Background The aim of this study was to evaluate the risk factors of wound dehiscence and determine which of them can be reverted. Methods We retrospectively analyzed 3500 laparotomies. Age over 75 years, diagnosis of cancer, chronic obstructive pulmonary disease, malnutrition, sepsis, obesity, anemia, diabetes, use of steroids, tobacco use and previous administration of chemotherapy or radiotherapy were identified as risk factors Results Fifteen of these patients developed wound dehiscence. Emergency laparotomy was performed in 9 of these patients. Patients who had more than 7 risk factors died. Conclusion It is important for the surgeon to know that wound healing demands oxygen consumption, normoglycemia and absence of toxic or septic factors, which reduces collagen synthesis and oxidative killing mechanisms of neutrophils. Also the type of abdominal closure may plays an important role. The tension free closure is recommended and a continuous closure is preferable. Preoperative assessment so as to identify and remove, if possible, these risk factors is essential, in order to minimize the incidence of wound dehiscence, which has a high death rate.

  13. [Treatment of surgical wound dehiscence by topical negative pressure therapy: Clinical case].

    Fresno-García, Carmen; Alconero-Camarero, Ana Rosa; Fernández-Carro, Belén


    Topical negative pressure therapy is an alternative treatment for complex wounds that consists of the direct application of sub-atmospheric pressure, obtaining a number of effects that are beneficial for tissues, promoting the healing of both acute and chronic wounds and complementing surgical procedures. We report the case of a 75 year old man diagnosed with surgical wound dehiscence after a femorotibial bypass graft, who was hospitalized again with the aim to perform the implantation of a topical negative pressure therapy in the infected wound. We designed a care plan for this patient following the steps of the scientific method and basing ourselves on the NANDA, NIC, and NOC taxonomies.

  14. Prophylactic resorbable synthetic mesh to prevent wound dehiscence and incisional hernia in high high-risk laparotomy. A pilot study of using TIGR Matrix mesh.

    Harald eSöderbäck


    Full Text Available BackgroundWound dehiscence and incisional hernia are potentially serious complications following abdominal surgery, especially if performed through a midline incision. Although prophylactic reinforcement with on-lay mesh has been shown to reduce this risk, a permanent mesh carries the risk of seroma formation, infection and persistent pain. The aim of this study was to assess the safety of a resorbable on-lay mesh to reinforce the midline suturein patients with high risk for wound dehiscence or incisional hernia.MethodSixteen patients with three or more risk factors for wound dehiscence or incisional hernia were included. A TIGR® Matrix mesh, composed of a mixture of 40% copolymer fibres of polyglycolide, polylactide, and polytrimethylene carbonate and 60% copolymer fibres of polylactide, and polytrimethylene carbonate, was placed on the aponeurosis with an overlap of 5 on either side, and fixated with continuous monofilament polydioxanone suture. All postoperative complications were registered at clinical follow-up. ResultsMean follow-up was nine months. One patient developed a seroma that needed drainage and antibiotic treatment. One patient had a wound infection that needed antibiotic treatment. There was no complication requiring a reoperation. No wound dehiscence or incisional hernia was seen.ConclusionOn-lay placement of TIGR® Matrix is safe, and may provide a feasible way of reinforcing the suture line in patients with high risk for postoperative wound dehiscence or incisional hernia. Larger samples are required, however, if one is to draw any conclusion regarding the safety and effectiveness of this technique,.

  15. Effect of Semi-quantitative Culture Results from Complex Host Surgical Wounds on Dehiscence Rates.

    Elmarsafi, Tammer; Garwood, Caitlin S; Steinberg, John S; Evans, Karen K; Attinger, Christopher E; Kim, Paul J


    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

  16. Photobiomodulation of surgical wound dehiscence in a diabetic individual by low-level laser therapy following median sternotomy

    Snehil Dixit


    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.

  17. Fibrin sealant prevents gastrointestinal anastomosis dehiscence in intra-abdominal sepsis.

    Wang, Xinbo; Ren, Jianan; Zhu, Weiming; Li, Ning; Li, Jieshou


    We observed the potential use of fibrin sealant as a therapeutic modality for successful resolution of gastrointestinal anastomosis dehiscence in intra-abdominal sepsis. Forty-eight patients (33 men and 15 women) suffering from intra-abdominal sepsis were subjected to prophylactic appliance of fibrin sealant during immediate primary anastomosis during the laparotomy. The perioperative management invariably involved fluid resuscitation, active suction drainage of the abdominal liquor puris, nutritional supplementation, and growth hormone. The total surgical-related success ratio was 91.7% (44/48) for primary anastomosis with fibrin sealant in intra-abdominal sepsis. Anastomotic leakage occurred in the other four patients, two of which died because of leakage complications in our hospital. The hospital stay after the operation was 30.2 +/- 12.0 days. There has been no sign of recurrence over a follow-up period of 1-15 months. It is concluded that fibrin sealant may be useful in preventing gastrointestinal anastomosis dehiscence in intra-abdominal sepsis.

  18. Wound Dehiscence after Wisdom Tooth Removal in Mandibular Mesioangular Class IB Impactions: Triangular Transposition Flap versus Envelope Flap

    Amin Rahpeyma


    Full Text Available Background and aims. Wound dehiscence after lower third molar surgery extends the postoperative treatment period and may cause long-standing pain. The aim of this study was to compare wound dehiscence after removal of wisdom teeth in the most prevalent mandibular impaction (mesioangular class IB by two different soft tissue flap designs. Materials and methods. Partially-erupted mandibular third molars with mesioangular class IB impaction (Pell and Gregory classification were selected. Split mouth technique was used to compare the two flap designs (envelope vs. triangular transposition flap—TTF. The patients were recalled one week and a month later and rechecked for dehiscence, infection, and dry socket formation. Results. There were no cases of infection in either group. However, three cases of dry socket in the envelope group and four in the TTF group were recorded. In the envelope group, dehiscence occurred in 43% of cases during the first week, with 67% of cases being a large dehiscence (diameters of more than 5 mm. Extra appointments (those requested by the patient exclusively related to the problem of the hole distal to the second molar were scheduled in 10% of cases in the envelope group. In the TTF group, dehiscence occurred during the first week for the same impaction in 19% of cases with large dehiscence cases occurring in 65% of cases and extra appointment rate at 4.1%. Conclusion. According to theresults in the evaluated operation, TTF may prevent postoperative wound dehiscence more probably than the envelope flap.

  19. Abdominal wound closure: current perspectives

    Williams ZF


    Full Text Available Zachary F Williams, William W Hope Department of Surgery, South East Area Health Education Center, New Hanover Regional Medical Center, Wilmington, NC, USA Abstract: This review examines both early and late wound complications following laparotomy closure, with particular emphasis on technical aspects that reduce hernia formation. 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.

  1. Abdominal wound closure. A randomized prospective study of 571 patients comparing continuous vs. interrupted suture techniques.

    Richards, P C; Balch, C M; Aldrete, J S


    A randomized, prospective study was designed to compare a continuous with an interrupted technique for closing an abdominal incision. Five hundred seventy-one patients were randomized between the closure methods and stratified as to type of wound: clean, clean-contaminated, or contaminated. In mid-line incisions, the dehiscence rate was 2.0% (5/244) for the continuous group versus 0.9% (2/229) for the interrupted group. The difference was not statistically significant. Ventral hernias formed in 2.0% (4/201) of the continuous group vs. 0.5% (1/184) of the interrupted group. The type of wound had no influence on the results. In oblique incisions, 0% (0/39) of wounds closed continuously dehised while 2% (1/50) of incisions closed interruptedly dehised. No ventral hernias formed. Further analysis of the data indicated that dehiscence was more likely related to improper surgical technique than to the method of closure. An abdominal incision could be closed with a continuous suture in approximately half the time required for placing interrupted sutures (20 vs. 40 minutes). A continuous closure is preferred because it is more expedient and because it has the same incidence of wound disruption compared with an interrupted closure. PMID:6297417

  2. A Case Report of Sanguis Draconis for Treating a Patient With Refractory Wound Dehiscence After Breast Cancer Chemotherapy.

    Zhang, Guizhen; Hua, Yafang; Jin, Xueqin; Yan, Chunmei


    Breast cancer is one of the most common female malignant tumors. According to data statistics, the incidence of breast cancer was 7% to 10% for a variety of malignant tumors, being only lower than that of uterine cancer. The methods of treating breast cancer are given priority over operative treatment and combined with chemotherapy and radiotherapy. However, exosmosis of chemotherapeutic drugs is a common complication of chemotherapy. Exosmosis of drugs can stimulate local organs to induce acute inflammatory reaction and necrosis, which finally lead to wound infection and difficulty in healing. In December 2013, a patient with full-thickness wound (an area of 5 × 3 cm) dehiscence at the completion of the second phase of chemotherapy for left breast cancer after radical operation was admitted to our department. Her wound had healed after radical operation. The patient followed an integrative therapy treatment protocol that consisted of an external application of a phytomedicine called Sanguis Draconis and combined with a series of conventional treatments, including 3M Transparent Dressing moist therapy, increase in nutrition, and prevention therapies for infection. The patient's integrative treatment program resulted in complete wound healing, and the successful completion of the late 6 courses of chemotherapy. The article describes the nursing experiences associated with this case study.

  3. Pectoralis Muscle Flap Repair Reduces Paradoxical Motion of the Chest Wall in Complex Sternal Wound Dehiscence

    Zeitani, Jacob; Russo, Marco; Pompeo, Eugenio; Sergiacomi, Gian Luigi; Chiariello, Luigi


    Background The aim of the study was to test the hypothesis that in patients with chronic complex sternum dehiscence, the use of muscle flap repair minimizes the occurrence of paradoxical motion of the chest wall (CWPM) when compared to sternal rewiring, eventually leading to better respiratory function and clinical outcomes during follow-up. Methods In a propensity score matching analysis, out of 94 patients who underwent sternal reconstruction, 20 patients were selected: 10 patients underwent sternal reconstruction with bilateral pectoralis muscle flaps (group 1) and 10 underwent sternal rewiring (group 2). Eligibility criteria included the presence of hemisternum diastases associated with multiple (≥3) bone fractures and radiologic evidence of synchronous chest wall motion (CWSM). We compared radiologically assessed (volumetric computed tomography) ventilatory mechanic indices such as single lung and global vital capacity (VC), diaphragm excursion, synchronous and paradoxical chest wall motion. Results Follow-up was 100% complete (mean 85±24 months). CWPM was inversely correlated with single lung VC (Spearman R=−0.72, p=0.0003), global VC (R=−0.51, p=0.02) and diaphragm excursion (R=−0.80, p=0.0003), whereas it proved directly correlated with dyspnea grade (Spearman R=0.51, p=0.02) and pain (R=0.59, p=0.005). Mean CWPM and single lung VC were both better in group 1, whereas there was no difference in CWSM, diaphragm excursion and global VC. Conclusion Our study suggests that in patients with complex chronic sternal dehiscence, pectoralis muscle flap reconstruction guarantees lower CWPM and greater single-lung VC when compared with sternal rewiring and it is associated with better clinical outcomes with less pain and dyspnea.

  6. Prolonged Negative Pressure Wound Therapy Followed by Split-Thickness Skin Graft Placement for Wide Dehiscence of Clamshell Incision After Bilateral Lung Transplantation: A Case Report.

    Suzuki, H; Watanabe, T; Okazaki, T; Notsuda, H; Niikawa, H; Matsuda, Y; Noda, M; Sakurada, A; Hoshikawa, Y; Aizawa, T; Miura, T; Okada, Y


    Clamshell incision is a standard approach for bilateral lung transplantation, providing a good operative field; however, once wide dehiscence occurs, its management is sometimes difficult because of intense immunosuppression and malnutrition of the recipient. A 22-year-old man with idiopathic pulmonary arterial hypertension underwent cadaveric bilateral lung transplantation through a clamshell incision using standard cardiopulmonary bypass. He developed wound dehiscence on postoperative day (POD) 20 that resulted in exposure of the bilateral fifth ribs and open pneumothorax. Considering the extreme malnutrition and emaciation of the recipient, we avoided initial closure of the dehiscence. After the debridement of necrotic tissue, negative pressure wound therapy was initiated on POD 25 and was continued for approximately 6 months with trafermin spray application. Eventually, the wound, including the fifth ribs, was completely covered with granulation tissue except for the wire tying the sternum. On POD 217, the patient underwent removal of the sternal wire followed by split-thickness skin grafting. His wound was successfully closed and he was discharged without activity limitation on POD 265.

    Dudley, L; Kettle, C; Thomas, P W; Ismail, K M K


    Objective To establish the feasibility of conducting a definitive randomised controlled trial (RCT) comparing the effectiveness of resuturing versus expectant management for dehisced perineal wounds. Design A multicentre pilot and feasibility RCT. Setting Ten UK maternity units from July 2011 to July 2013. Population Eligible women with a dehisced perineal wound within 2 weeks of childbirth. Methods The interventions were resuturing or expectancy. Randomisation was via web or telephone, stratified by participating centre. Blinding was not possible due to the nature of the interventions. Analysis was by intention-to-treat. Outcome The primary outcome measure was wound healing at 6–8 weeks. Results The study revealed a number of feasibility issues, particularly strong patient and clinician preference for treatment options at recruiting centres and the timing of the primary outcome measure. Thirty-four women were randomised (17 in each arm). Data from 33 women were analysed on an intention-to-treat analysis to obtain preliminary estimates of effect size. There was a difference in wound healing at 2 weeks favouring resuturing (OR 20.00, 95% CI 2.04 to 196.37, p=0.004). However, by 6–8 weeks all but one wound in both groups had healed. Conclusions PREVIEW revealed a number of feasibility issues, which impacted on recruitment rate. These will have to be taken into account in the design of any future definitive study. In this feasibility study, resuturing was associated with quicker wound healing and women reported higher satisfaction rates with the outcome at 3 months. Trial registration number ISRCTN05754020.

  11. Use of negative pressure wound therapy in the management of infected abdominal wounds containing mesh: an analysis of outcomes.

    Baharestani, Mona Mylene; Gabriel, Allen


    The purpose of this study was to examine the clinical outcomes of negative pressure wound therapy (NPWT) using reticulated open-cell foam (ROCF) in the adjunctive management of abdominal wounds with exposed and known infected synthetic mesh. A non randomised, retrospective review of medical records for 21 consecutive patients with infected abdominal wounds treated with NPWT was conducted. All abdominal wounds contained exposed synthetic mesh [composite, polypropylene (PP), or knitted polyglactin 910 (PG) mesh]. Demographic and bacteriological data, wound history, pre-NPWT and comparative post-NPWT, operative procedures and complications, hospital length of stay (LOS) and wound healing outcomes were all analysed. Primary endpoints measured were (1) hospital LOS prior to initiation of NPWT, (2) total time on NPWT, (3) hospital LOS from NPWT initiation to discharge and (4) wound closure status at discharge. A total of 21 patients with abdominal wounds with exposed, infected mesh were treated with NPWT. Aetiology of the wounds was ventral hernia repair (n = 11) and acute abdominal wall defect (n = 10). Prior to NPWT initiation, the mean hospital LOS for the composite, PP and PG meshes were 76 days (range: 21-171 days), 51 days (range: 32-62 days) and 19 days (range: 12-39 days), respectively. The mean hospital LOS following initiation of NPWT for wounds with exposed composite, PP and PG mesh were 28, 31 and 32 days, respectively. Eighteen of the 21 wounds (86%) reached full closure after a mean time of 26 days of NPWT and a mean hospital LOS of 30 days postinitiation of NPWT. Three wounds, all with composite mesh left in situ, did not reach full closure, although all exhibited decreased wound dimensions, granulating beds and decreased surface area exposure of mesh. During NPWT/ROCF, one hypoalbuminemic patient with exposed PP mesh developed an enterocutaneous fistula over a prior enterotomy site. This patient subsequently underwent total mesh extraction, takedown of

    Slater, N.J.


    Incisional hernia is by far the most common complication after laparotomies, occurring in 10 – 20%. Its occurrence is secondary to insufficient healing of the postoperative scar, resulting in wound dehiscence and protrusion of abdominal contents through an opening in the musculo-fascial layer of the

    A. Pérez García


    Full Text Available La mediastinitis es una de las complicaciones más graves de la cirugía cardíaca. Aparece en el 0,5-5 % de las esternotomías y esta incidencia es mucho mayor en pacientes diabéticos, obesos, inmunodeprimidos, con enfermedad pulmonar obstructiva crónica (EPOC, etc. Presentamos el caso de una paciente diabética, obesa mórbida, que sufre mediastinitis tras doble by-pass coronario. Para la cobertura del defecto se empleó un colgajo de epiplon tunelizado transdiafragmático. El colgajo omental permite cubrir grandes defectos además de que posee capacidad antimicrobiana y favorece la revascularización tisular. Las características de este colgajo hacen que actualmente deba considerarse como primera elección en pacientes con grandes defectos esternales y trastornos de la inmunidad y la cicatrización.Mediastinitis is one of the most serious complications from cardiac surgery. It is reported to occur in 0'5-5 % of sternotomy incisions, and this incidence is much higher in diabetic patients, obese, immunocompromised, COPD, etc. We report a case of a diabetic and morbid obese woman suffering mediastinitis after double coronary bypass surgery. For the reconstruction a transdiaphragmatic tunnelled omental flap was used. The omentum is useful to cover large defects. It has antiinfective properties and promotes revascularization of neighbouring tissues. Omental flap can be a highly effective treatment for patients with large sternal wounds and immune disorders and wound healing disorders.

  15. Matching Biological Mesh and Negative Pressure Wound Therapy in Reconstructing an Open Abdomen Defect

    Fabio Caviggioli


    Full Text Available Reconstruction of open abdominal defects is a clinical problem which general and plastic surgeons have to address in cooperation. We report the case of a 66-year-old man who presented an abdominal dehiscence after multiple laparotomies for a sigmoid-rectal adenocarcinoma that infiltrated into the abdominal wall, subsequently complicated by peritonitis and enteric fistula. A cutaneous dehiscence and an incontinent abdominal wall resulted after the last surgery. The abdominal wall was reconstructed using a biological porcine cross-linked mesh Permacol (Covidien Inc., Norwalk, CT. Negative Pressure Wound Therapy (NPWT, instead, was used on the mesh in order to reduce wound dimensions, promote granulation tissue formation, and obtain secondary closure of cutaneous dehiscence which was finally achieved with a split-thickness skin graft. Biological mesh behaved like a scaffold for the granulation tissue that was stimulated by the negative pressure. The biological mesh was rapidly integrated in the abdominal wall restoring abdominal wall continence, while the small dehiscence, still present in the central area, was subsequently covered with a split-thickness skin graft. The combination of these different procedures led us to solve this complicated case obtaining complete wound closure after less than 2 months.

  16. Abdominal Cavity Eventration Treated by Means of the „Open Abdomen” Technique Using the Negative Pressure Therapy System – Case Report and Literature Review

    Trzeciak Piotr W.; Porzeżyńska Joanna; Ptasińska Karolina; Walczak Dominik A.


    Wound dehiscence is a surgical complication in which the wound ruptures along the surgical suture with abdominal cavity bowel displacement. It is observed in 0.2-6% of operated patients. The extensive wound is a gateway for infection. Moreover, increased secretion of serous fluid induces a hygienic problem and may lead to secondary skin infections or bedsores. The negative pressure wound therapy (NPWT) system is an innovative therapeutic method. It perfectly executes the TIME strategy, receiv...

  17. Prevention of abdominal wound infection (PROUD trial, DRKS00000390: study protocol for a randomized controlled trial

    Heger Ulrike


    Full Text Available Abstract Background Wound infection affects a considerable portion of patients after abdominal operations, increasing health care costs and postoperative morbidity and affecting quality of life. Antibacterial coating has been suggested as an effective measure to decrease postoperative wound infections after laparotomies. The INLINE metaanalysis has recently shown the superiority of a slowly absorbable continuous suture for abdominal closure; with PDS plus® such a suture has now been made available with triclosan antibacterial coating. Methods/Design The PROUD trial is designed as a randomised, controlled, observer, surgeon and patient blinded multicenter superiority trial with two parallel groups and a primary endpoint of wound infection during 30 days after surgery. The intervention group will receive triclosan coated polydioxanone sutures, whereas the control group will receive the standard polydioxanone sutures; abdominal closure will otherwise be standardized in both groups. Statistical analysis is based on intention-to-treat population via binary logistic regression analysis, the total sample size of n = 750 is sufficient to ensure alpha = 5% and power = 80%, an interim analysis will be carried out after data of 375 patients are available. Discussion The PROUD trial will yield robust data to determine the effectiveness of antibacterial coating in one of the standard sutures for abdominal closure and potentially lead to amendment of current guidelines. The exploration of clinically objective parameters as well as quality of life holds immediate relevance for clinical management and the pragmatic trial design ensures high external validity. Trial Registration The trial protocol has been registered with the German Clinical Trials Register (DRKS00000390.

  18. Efficacy and Safety of a Continuous Wound Catheter in Open Abdominal Partial Hepatectomy.

    Che, Lu; Lu, Xin; Pei, Li-Jian


    Objective To investigate the efficacy and safety of continuous local anesthetic wound infiltration following open abdominal partial hepatectomy. Methods We performed a prospective, non-randomized, concurrent and controlled study. Patients undergoing open abdominal partial hepatectomy, according to their willingness, accepted one of the following managements for the postoperative pain: continuous wound catheter (CWC) infiltration, patient-controlled epidural analgesia (PCEA), patient-controlled intravenous analgesia of morphine (PCIAM), and patient-controlled intravenous analgesia of sufentanil (PCIAS). The primary outcome was postoperative visual analogue scale (VAS) scores at rest and on movement. Secondary outcomes included consumption of rescue medication, side effects, and complications associated with postoperative pain management. Results From August 2013 to December 2013, 80 patients were allocated to receive CWC (n=10), PCEA (n=22), PCIAM (n=29), or PCIAS (n=19). After adjusting for age, sex, body mass index, percentage of resected liver, operation time, and Amsterdam Preoperative Anxiety and Information Scale, there was no significant difference in the VAS scores at rest or on movement between Group CWC and the other groups, namely PCEA, PCIAM, and PCIAS, at 4, 12, 48, and 72 hours postoperatively (all P>0.05). The need for rescue medication was not significantly different between Group CWC and the other three groups at 48 and 72 hours postoperatively (all P>0.05). There was no significant difference in the incidence of postoperative nausea and vomiting or anal exsufflation time between group CWC and the other three groups (all P>0.05). No severe adverse effects associated with continuous wound infiltration were observed during the study period. Conclusions CWC has a comparable analgesic effect compared with traditional analgesia Methods at most time points postoperatively. CWC is a safe alternative for the postoperative analgesic management of open liver

  19. [Should routine exploratory laparotomy be performed in the presence of an abdominal wound? Discussion apropos of 176 cases].

    Guiberteau, B; Kohen, M; Borde, L; Sartre, J Y; Bourseau, J C; Le Neel, J C


    Management of abdominal wounds is presently the subject of discussion between the partisans of routine laparotomy and those preferring "armed" surveillance. Results of study of a series of 176 abdominal wounds subjected to surgical dogma showed: that the diagnosis of non penetrating wounds (17.6%) was not always evident, due either to their anatomical localization (frontier region wounds) or to insufficient local exploration in urgent cases (6.6% of false-negatives), that the existence of serious clinical signs (50 cases) was always associated with one or more visceral lesions, requiring urgent laparotomy with a morbidity of 20% and a mortality of 8% (4 cases), that in the case of asymptomatic penetrating wounds (96 cases), routine laparotomy did nevertheless allow the diagnosis of visceral lesions in 50 cases (including 23 major lesions) but was of no utility in 46 cases (31.5% of blind laparotomies for the total series). The elevated proportion of useless laparotomies (30% in the literature), the result of a dogmatic attitude, or the risk of a delayed intervention (5 to 8%) in the series practising the selective method, led to a modification in the authors' attitude. The existence of serious signs should obviously result in a laparotomy. In their absence, and when confronted with a penetrating or doubtful (frontier region) wound, an exploratory celioscopy is proposed to ensure complete abdominal exploration, to confirm the presence or absence of penetration, to treat minimal lesions and to perform a classical laparotomy in case of evident necessity.

  20. Reconstruction of Abdominal Wall of a Chronically Infected Postoperative Wound with a Rectus Abdominis Myofascial Splitting Flap

    Sung Kyu Bae


    Full Text Available BackgroundIf a chronically infected abdominal wound develops, complications such as peritonitis and an abdominal wall defect could occur. This could prolong the patient's hospital stay and increase the possibility of re-operation or another infection as well. For this reason, a solution for infection control is necessary. In this study, surgery using a rectus abdominis muscle myofascial splitting flap was performed on an abdominal wall defect.MethodsFrom 2009 to 2012, 5 patients who underwent surgery due to ovarian rupture, cesarean section, or uterine myoma were chosen. In each case, during the first week after operation, the wound showed signs of infection. Surgery was chosen because the wounds did not resolve with dressing. Debridement was performed along the previous operation wound and dissection of the skin was performed to separate the skin and subcutaneous tissue from the attenuated rectus muscle and Scarpa's fascial layers. Once the anterior rectus sheath and muscle were adequately mobilized, the fascia and muscle flap were advanced medially so that the skin defect could be covered for reconstruction.ResultsUpon 3-week follow-up after a rectus abdominis myofascial splitting flap operation, no major complication occurred. In addition, all of the patients showed satisfaction in terms of function and esthetics at 3 to 6 months post-surgery.ConclusionsUsing a rectus abdominis myofascial splitting flap has many esthetic and functional benefits over previous methods of abdominal defect treatment, and notably, it enabled infection control by reconstruction using muscle.

SSIs increase postoperative morbidity and mortality, and may require hospital admission, intravenous antibiotics, and even surgical reintervention. Risks associated with SSIs are related to both host and perioperative factors. However, a vast majority of these infections are preventable. More recently, quality initiative programs such as American College of Surgeons National Surgical Quality Improvement Program are expanding their roles to help better monitor adherence to improvement measures. Indeed, standardizing preoperative antibiotic prophylaxis timing is perhaps the most persuasive example and this has been integral to reducing postoperative SSI rates. Herein, the authors provide an update on the epidemiology, risk factors, identification, and management of wound infections following abdominal surgery.

  2. The spectrum of injuries resulting from posterior abdominal stab wounds: a South African experience.

    Kong, V Y; Oosthuizen, G V; Clarke, D L


    The spectrum of injury associated with anterior abdominal stab wounds (SWs) is well established. The literature on the spectrum of organ injury associated with SWs to the posterior abdomen, however, is limited. We reviewed our experience of 105 consecutive patients who had established indications for laparotomy managed over a 4-year period in a high volume trauma service in South Africa. Of the 105 patients, 97 (92%) were male and the overall mean age was 24 years. Fifty-seven patients (54%) had immediate indications for laparotomy. The remaining 48 patients (46%) initially underwent active clinical observation and the indications for laparotomy became apparent during the observation period. Of the 105 laparotomies performed, 94 (90%) were positive and 11 (10%) were negative. Of the 94 positive laparotomies, 92 were therapeutic and 2 were non-therapeutic. A total of 176 organ injuries were identified: 50 (53%) of the 94 patients sustained a single organ injury while the remaining 44 (47%) sustained multiple organ injuries. The most commonly injured organs were the colon (n=63), spleen (n=21) and kidney (n=19). The pattern of intra-abdominal injuries secondary to SWs to the posterior abdomen is different to that seen with the anterior abdomen. Colonic injury is most commonly encountered, followed by injuries to the spleen and kidney. Clinicians must remain vigilant because of the potential for occult injuries.

    Buszewska-Forajta, M; Siluk, D; Daghir-Wojtkowiak, E; Sejda, A; Staśkowiak, D; Biernat, W; Kaliszan, R


    Grasshopper, belonging to Chorthippus sp., is a widespread insect inhabiting Polish territory. According to folk knowledge and folk tales, the grasshopper abdominal secretion was used by villagers of Central and South-West Poland as a natural drug accelerating the wound healing process. In the reported study the hypothesis about beneficial properties of grasshopper abdominal secretion on hard to heal wounds was verified. The study was carried out with the use of a murine model (mice C57BL/6). In order to verify the beneficial properties of grasshopper abdominal secretion, the wounds of 8mm in diameter were formed on one side of each tested mouse. The influence of ethanolic extract of insects' secretion on healing process was evaluated in comparison to ethanolic solution of allantoin and 30% aqueous solution of ethanol (medium). The observation was carried out over a 14 day period. Finally the statistical analysis (ANOVA) was carried out to highlight the differences in wound healing rate between applied preparations. Moreover, qualitative composition of grasshoppers' secretion was studied with the use of GC/MS technique. During the first three days of observation, wounds treated with allantoin were healed with higher efficiency in comparison to ethanol and insect secretion preparations. The trend of healing changed from the 4th day of observation. Wounds treated with grasshoppers' abdominal secretion were closuring faster than wounds treated with allantoin or ethanol. In this part of observation, in the case of allantoin and ethanol application, the wound healing efficiency was similar. Since the 9th day of experiment the measurement of wounds size was problematic, due to crust formation. Finally at the 14th day of the study, wounds were totally healed. Morphological study enabled to observe all the phases of healing. In the 5th and 8th day, the infiltration of neutrophils and mononuclear cells in dermis was observed, which is characteristic for inflammatory phase

    Jiang PU


    Full Text Available Objective  To investigate the effects of progesterone on gastric mucosal inflammatory response, changes in mucosa structure, and cell apoptosis in rats with open abdominal wound and seawater immersion. Methods  Thirty male Wistar rats were randomly divided into 3 groups (10 each. The rats in group A were subjected to open abdominal wound + subcutaneous injection of sterile water, and rats in group B to open abdominal wound + seawater immersion + subcutaneous injection of sterile water, and rats in group C to open abdominal wound + seawater immersion + progesterone treatment. The animal model of open abdominal wound and seawater immersion was reproduced, and the rats in groups B and C were given subcutaneous injection of sterile water or progesterone (16mg/kg at 1, 6 and 12h after immersion. All rats were executed at 16h after immersion. The ulcer index (UI of gastric mucosa was calculated in the three groups. The pathological changes in gastric mucosa were observed under light microscope. The concentrations of tumor necrosis factor-alpha (TNF-α and interleukin-6 (IL -6 in gastric mucosa were measured by enzyme-linked immunoassay, the expression of caspase-3 in gastric mucosa was detected by immunohistochemistry, and the cell apoptosis of gastric mucosa was determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling staining. Results  The UI, concentrations of TNF-α and IL-6, and injury score of gastric mucosa in group B were all significantly higher than those in group A (P<0.01 and group C (P<0.05. The expression of caspase-3 (23.8%±3.5% and apoptosis index (26.4%±2.8% of the gastric mucosa in group B were higher than those in group A (10.2%±1.6% and 8.5%±1.5% respectively, P<0.01 and group C (17.1%±2.3% and 19.8%±2.4% respectively, P<0.05. Conclusion  Progesterone administration could suppress gastric mucosa inflammation, protect gastric mucosal structure, and reduce mucosal cell apoptosis in the rats

  6. Tacrolimus does not affect early wound healing in a rodent model of bowel anastomoses and abdominal wall closure.

    Martine C M Willems

    Full Text Available BACKGROUND: Use of immunosuppressant drugs has been associated with complications in wound healing. The calcineurin inhibitor tacrolimus is thought to have a relatively low complication rate, but preclinical research has yielded contradictory data, prompting the current comprehensive study. METHODS: Three groups of 33 male Wistar rats received a daily subcutaneous dose of 0,5, 2 or 5 mg/kg tacrolimus. A control group received saline. On day 0 a resection of 1 cm ileum and 1 cm colon was performed, and end-to-end anastomoses were constructed. Ten rats of each group were killed on day 3 and day 5 and the remaining animals on day 7. Both anastomoses and the wound in the abdominal wall were analyzed. Wound strength was the primary outcome parameter. RESULTS: Mean strength of the abdominal wall increased significantly over time in all groups (p<0.0001. Both the breaking strength and the bursting pressure of the ileum and colon anastomoses followed the same pattern. No differences were observed between control and experimental groups. In addition, no consistent differences were found between groups regarding wound hydroxyproline content and the activities of matrix metalloproteinase-2 and -9. CONCLUSION: Tacrolimus does not affect early wound healing.

  7. A comparative study of outcome of the absorbable suture polydioxanone and nonabsorbable suture polypropylene in laparotomy wound closure

    Kiran Shankar H.


    Full Text Available Background: Abdominal wound closure is one of the common operations for a general surgeon. Prevention of complications is important to reduce post-operative morbidity and mortality. Post-operative wound pain, wound infection, wound dehiscence, suture sinus formation; palpable knots and incisional hernia are the parameters are to be studied. Therefore, the present study was undertaken to compare polydioxanone and polypropylene suture material for abdominal fascial closure regarding morbidity in terms of post-operative wound complications. Methods: Patients admitted in the department of surgery, who undergo laparotomy operations, with midline abdominal incisions were included in the study. The recruited subjects were divided into Group-A, whom abdominal incisions are closed with non-absorbable suture material polypropylene and Group-B whom abdominal incisions are closed with absorbable suture material polydioxanone. Data was expressed as percentages. Results: The incidence of wound pain was observed in all the patients in both immediate and delayed post-operative period in the polypropylene suture material compared to polydioxanone. The incidence of wound infection was higher in polypropylene (24% compared to PDS (2%. There were 4% cases of wound dehiscence in the present study. The incidence of suture sinus formation was higher in the polypropylene suture material (9% compared to the polydioxanone suture material (2% in the delayed postoperative period. The incidence of palpable knots was higher in the polypropylene suture material (23% compared to the polydioxanone suture material. No cases of incisional hernia were reported with polydioxanone suture material. Conclusions: The overall morbidity from abdominal closure was considerably reduced in the Polydioxanone group. We encountered reduction in wound complications like burst abdomen, wound infection, wound pain, suture sinus formation, palpable knots and incisional hernia. Therefore

    Turnock, Adam R; Fleischer, Brian P; Carney, Martin J; Vanderlan, Wesley B


    Abdominal compartment syndrome (ACS) is a known complication of laparotomy; however, the literature is lacking in regards to treatment of this entity in pregnant patients. We present a case of acute perforated appendicitis in a second trimester primagravida, complicated by gangrenous necrosis of the contiguous bowel with subsequent development of ACS and intra-abdominal sepsis. This was treated with a novel approach, using non-commercial negative pressure wound therapy and open abdomen technique. Gestational integrity was preserved and the patient went on to experience a normal spontaneous vaginal delivery. At 5 years post-delivery the patient has had no surgical complications and her baby has met all developmental milestones.

  10. A new classification of post-sternotomy dehiscence

    Jaime Anger


    Full Text Available The dehiscence after median transesternal sternotomy used as surgical access for cardiac surgery is one of its complications and it increases the patient's morbidity and mortality. A variety of surgical techniques were recently described resulting to the need of a classification bringing a measure of objectivity to the management of these complex and dangerous wounds. The different related classifications are based in the primary causal infection, but recently the anatomical description of the wound including the deepness and the vertical extension showed to be more useful. We propose a new classification based only on the anatomical changes following sternotomy dehiscence and chronic wound formation separating it in four types according to the deepness and in two sub-groups according to the vertical extension based on the inferior insertion of the pectoralis major muscle.

  11. A modified parasternal wire technique for prevention and treatment of sternal dehiscence.

    Sharma, Rajeev; Puri, Deepak; Panigrahi, Bishnu P; Virdi, Inderjeet S


    Sternal dehiscence with or without mediastinitis is a devastating complication of median sternotomy. Various techniques of sternotomy closure including 'figure of eight' wire sutures, nylon bands, and custom-made titanium-H plates have been described. We have devised and tested a new method of sternal closure to prevent sternal wound complications in patients at high risk of sternal dehiscence. 1336 patients underwent sternotomy for various cardiac operations from January 1996 to January 2002. Patients were divided into two groups. Group I consisted of 560 patients who did not have any high risk factors for sternal dehiscence and received a standard six wire closure. Group II comprised of patients at high risk of sternal dehiscence and were divided randomly into subgroup II A (n = 390), which included patients who had conventional sternal closure. While in subgroup II B (n = 386) patients had a modified parasternal wire closure according to the finalized protocol. Sternal instability was noticed in 1/560 and none had sternal dehiscence in group I, but 16/390 patients had sternal instability and 3/390 had sternal dehiscence in subgroup II A, whereas only one patient in high risk subgroup II B developed sternal dehiscence with mediastinitis and required a pectoral flap advancement for sternal closure. Use of modified parasternal wire closure in patients with a high risk of sternal dehiscence is a safe, effective, technically easily reproducible, as well as economical, method of preventing and treating sternal dehiscence.

  12. The correlation between stabbing-related upper extremity wounds and survival of stabbing victims with abdominal and thoracic injuries.

    Rozenfeld, Michael; Peleg, Kobi; Givon, Adi; Kessel, Boris


    When treating patients with stab injuries of the torso, clinicians often lack timely information about the degree and nature of internal organ damage. An externally observable sign significantly associated with characteristics of torso injuries may therefore be useful for practitioners. One such potential sign is the presence of wounds to the hands, sometimes sustained during victims' attempt to defend themselves during the violent altercation. Thus, the primary aim of this study was to evaluate the association between presence of upper extremity wounds and the severity of the thoracic and intra-abdominal injuries due to stabbing. This study was carried out retrospectively using data on 8714 patients with stabbing-related injuries from 19 trauma centers that participated in the Israeli National Trauma Registry (INTR) between January 1st1997 and December 31st 2013. Patients with wounds of upper extremities in addition to torso injuries (UE group) were compared to other patients with torso injuries (TO group) in terms of demographics, injury characteristics and clinical outcome. The compared groups were found to be homogeneous in terms of age and systolic blood pressure; the number of sustained torso injuries was also identical. The UE group comprised a slightly greater percentage of females, however both groups were predominantly male. Patients with upper extremity injuries had a lower proportion of internal organ damage (36% vs. 38.5%) and lower mortality (0.9% vs. 2%). The higher mortality of patients without upper extremity wounds remained significantly different even when adjusted by other epidemiological parameters (OR 2.46, 95% CI 1.33-5.08).The number of sustained upper extremity injuries was positively associated with deeper penetration of the torso by the stabbing instrument. Patients with stabbing-related upper extremity wounds had a significant survival advantage over patients without such injuries. However, a greater number of sustained upper extremity

  13. The Effect of Honey Gel on Abdominal Wound Healing in Cesarean Section: A Triple Blind Randomized Clinical Trial

    Maryam Nikpour


    Full Text Available Objective: To assess whether honey can accelerate the wound healing in women undergoing cesarean section. Methods: This was a triple blinded randomized prospective clinical trial. Women with cesarean section were randomly designated as drug (37 cases and placebo (38 cases groups. The drug group received local honey gel 25% while the placebo group received similar free-honey gel on abdominal cesarean incision twice a day for 14 days. REEDA scale (Redness, Edema, Ecchymosis, Discharge and Approximation of wound edges was used to assess wound healing. Results: The mean REEDA was 2.27 ± 2.46 and 3.91 ± 2.74 (p=0.008 on the 7th day and 0.47 ± 0.84 and 1.59± 1.95 (p=0.002 on the 14th day for the drug and placebo groups, respectively. Redness, edema and hematoma in the drug group were significantly lower on the 7th and 14th days. Conclusion: Honey was effective in healing the cesarean section incision. Using topical honey is suggested as a natural product with rare side effects in order to reduce the complications of cesarean wounds.

  14. Application of a Silicone Sheet in Negative-Pressure Wound Therapy to Treat an Abdominal Wall Defect after Necrotizing Fasciitis

    Shin, Jin Su


    Necrotizing fasciitis (NF) is an aggressive soft-tissue infection involving the deep fascia and is characterized by extensive deterioration of the surrounding tissue. Immediate diagnosis and intensive treatment, including debridement and systemic antibiotics, represent the most important factors influencing the survival of NF patients. In this report, we present a case of NF in the abdomen due to an infection caused by a perforated small bowel after abdominal liposuction. It was successfully treated using negative-pressure wound therapy, in which a silicone sheet functioned as a barrier between the sponge and internal organs to protect the small bowel. PMID:28194352

  15. Abdominal Cavity Eventration Treated by Means of the "Open Abdomen" Technique Using the Negative Pressure Therapy System--Case Report and Literature Review.

    Trzeciak, Piotr W; Porzeżyńska, Joanna; Ptasińska, Karolina; Walczak, Dominik A


    Wound dehiscence is a surgical complication in which the wound ruptures along the surgical suture with abdominal cavity bowel displacement. It is observed in 0.2-6% of operated patients. The extensive wound is a gateway for infection. Moreover, increased secretion of serous fluid induces a hygienic problem and may lead to secondary skin infections or bedsores. The negative pressure wound therapy (NPWT) system is an innovative therapeutic method. It perfectly executes the TIME strategy, receiving more and more recognition. The study presented a case of a 62-year old male patient after several consecutive wound dehiscence episodes who was primarily treated for rectal cancer by means of low anterior resection of the rectum. Due to acute respiratory insufficiency after several operations, wound necrosis with dehiscence was observed. Considering the high risk of perioperative death we abandoned surgical treatment and introduced conservative management using negative pressure wound therapy until the patient's health improved. Literature regarding the above-mentioned issue was also reviewed.

  17. The Dehiscent Facial Nerve Canal

    Sertac Yetiser


    Full Text Available Accidental injury to the facial nerve where the bony canal defects are present may result with facial nerve dysfunction during otological surgery. Therefore, it is critical to know the incidence and the type of facial nerve dehiscences in the presence of normal development of the facial canal. The aim of this study is to review the site and the type of such bony defects in 144 patients operated for facial paralysis, myringoplasty, stapedotomy, middle ear exploration for sudden hearing loss, and so forth, other than chronic suppurative otitis media with or without cholesteatoma, middle ear tumors, and anomaly. Correlation of intraoperative findings with preoperative computerized tomography was also analyzed in 35 patients. Conclusively, one out of every 10 surgical cases may have dehiscence of the facial canal which has to be always borne in mind during surgical manipulation of the middle ear. Computerized tomography has some limitations to evaluate the dehiscent facial canal due to high false negative and positive rates.

  18. Postoperative infection of an abdominal mesh due to methicillin resistant Staphylococcus Aureus - A case report

    Ashok R


    Full Text Available Methicillin resistant Stephylococcus aureus (MRSA infection has now become a major problem in hospitals. We present a case of postoperative infection MRSA where the primary source of the infection was found to be an abdominal mesh that was used to reinforce the abdominal wall. After one year of surgery, the patient developed wound dehiscence and discharge. MRSA was isolated from the wound, mesh, external nares, throat and axilla. Initially she was started on clindamycin and discharged from the hospital. After 5 months, patient came back to the hospital with infection at the same site. The patient was then treated with vancomycin and MRSA clearance. She responded to the treatment with complete healing of the wound and clearance of MRSA.

    Highlights: • CT with multiplanar reformations can accurately display the sigmoid platet dehiscence. • The prevalence of sigmoid plate dehiscence was no significant difference among different age groups. • The size of sigmoid plate bony defects were not statistically different among different age groups. • The sigmoid plate dehiscence is more commonly a congenital than an acquired condition. - Abstract: Background and purpose: The imaging features of sigmoid plate dehiscence-induced pulsatile tinnitus have been presented. The origin of the sigmoid plate dehiscence, however, remains unclear. Our aim was to assess the prevalence and extent of sigmoid plate dehiscence on computed tomography (CT) images in multiple age groups to determine whether this condition is more likely to be congenital or acquired. Materials and methods: We retrospectively reviewed contrast-enhanced CT images of sigmoid plates of temporal bones in 504 patients. Each temporal bone was characterized as normal or dehiscent. Patients were then subcategorized into four age groups, and the prevalence and extent of dehiscent sigmoid plates in each group were calculated and compared. Results: Overall, 80 patients had sigmoid plate dehiscence, nine of whom had it bilaterally. In successively older age groups, the prevalences of sigmoid plate dehiscence were 18.9%, 20.1%, 14.5%, and 12.7%, respectively. Respective average anteroposterior bony defect diameters were 3.7 ± 1.7, 3.0 ± 1.3, 3.1 ± 1.5, and 3.0 ± 1.1 mm. Respective average vertical bony defect diameters were 3.6 ± 2.3, 2.6 ± 1.2, 3.2 ± 1.5, and 3.0 ± 1.7 mm. The prevalence and extent of sigmoid plate dehiscence were not statistically different among the four age groups. Conclusions: The similar radiologic prevalence and extent of dehiscent sigmoid plates among the age groups suggest that the dehiscence is more commonly a congenital than an acquired condition.

  20. Otic capsule dehiscence syndrome: Superior semicircular canal dehiscence syndrome with no radiographically visible dehiscence.

    Wackym, P Ashley; Wood, Scott J; Siker, David A; Carter, Dale M


    We conducted a prospective longitudinal study of two cohorts of patients who had superior semicircular canal dehiscence syndrome (SSCDS); one group had radiographically confirmed superior canal dehiscence (SCD), and the other exhibited no identified otic capsule dehiscence on imaging (no-iOCD). We compiled data obtained from prospective structured symptomatology interviews; diagnostic studies; three-dimensional, high-resolution, temporal bone computed tomography; and a retrospective case review from our tertiary care referral center. Eleven adults and 1 child with SSCDS were identified, surgically managed, and followed. Six of these patients-1 man and 5 women, aged 29 to 54 years at first surgery (mean: 41.8)-had radiologically confirmed SCD. The other 6 patients-1 man, 4 women, and 1 girl, aged 1 to 51 years (mean: 32.2)-had no-iOCD. The 6 adults with SCD underwent surgery via a middle cranial fossa approach with plugging procedures. The 5 adults and 1 child with no-iOCD underwent round window reinforcement (RWR) surgery. One SCD patient developed no-iOCD 1.5 years after SCD surgery, and she subsequently underwent RWR surgery. Our main outcome measures were patient symptomatology (with video documentation) and the results of diagnostic studies. Other than the character of migraine headaches, there was no difference in preoperative symptomatology between the two groups. Postoperatively, resolution of SSCDS symptoms ultimately occurred in all patients. Both the SCD and the no-iOCD groups experienced a highly significant improvement in postural control following treatment (Wilcoxon signed rank test, p syndrome more accurately reflects the clinical syndrome of SSCDS since it includes both superior semicircular canal dehiscence and no-iOCD, as well as posterior and lateral semicircular canal dehiscence, all of which can manifest as SSCDS. We have also included links to videos in which 4 of the SSCDS patients with no-iOCD in this study discussed their symptoms and the

  4. Comparative study of the microvascular blood flow in the intestinal wall, wound contraction and fluid evacuation during negative pressure wound therapy in laparostomy using the V.A.C. abdominal dressing and the ABThera open abdomen negative pressure therapy system.

    Lindstedt, Sandra; Malmsjö, Malin; Hlebowicz, Joanna; Ingemansson, Richard


    This study aimed to compare the changes in microvascular blood flow in the small intestinal wall, wound contraction and fluid evacuation, using the established V.A.C. abdominal dressing (VAC dressing) and a new abdominal dressing, the ABThera open abdomen negative pressure therapy system (ABThera dressing), in negative pressure wound therapy (NPWT). Midline incisions were made in 12 pigs that were subjected to treatment with NPWT using the VAC or ABThera dressing. The microvascular blood flow in the intestinal wall was measured before and after the application of topical negative pressures of −50, −75 and −125mmHg using laser Doppler velocimetry. Wound contraction and fluid evacuation were also measured. Baseline blood flow was defined as 100% in all settings. The blood flow was significantly reduced to 64·6±6·7% (P blood flow was significantly reduced to 39·6±6·7% (P blood flow could be observed between the two groups. The ABThera system afforded significantly better fluid evacuation from the wound, better drainage of the abdomen and better wound contraction than the VAC dressing.

  5. Our experience with pectoralis major flap for management of sternal dehiscence: A review of 25 cases

    Parag Sahasrabudhe


    Full Text Available Objective: To report our experience of the pectoralis major flap as the treatment modality for post coronary artery bypass sternal wound dehiscence. Materials and Methods: A retrospective study of 25 open heart surgery cases, performed between January 2006 and December 2010 at Deenanath Mangeshkar Hospital, Pune, was carried out. Unilateral or bilateral pectoralis major muscle flap by the double breasting technique using rectus extension was used in the management of these patients. The outcome was assessed on the basis of efficacy of flap surgery in achieving wound healing and post-surgery shoulder joint movements to evaluate donor site morbidity. The follow-up ranged from 5 months to 3.5 years. Results: Twenty-three (92% patients were discharged with complete wound closure. One patient (4% had wound dehiscence after flap surgery. One patient (4% died in the hospital in the immediate postoperative period due to mediastinitis. No recurrent sternum infection has occurred till date in 24 patients (96%. For one patient (4% who had wound dehiscence, daily dressing was done and wound healing was achieved with secondary intension. At follow-up, shoulder joint movements were normal in all the patients. Conclusions: The double breasting technique of the pectoralis major muscle flaps with rectus sheath extension is efficient in covering the entire length of the defect and can reduce the morbidity, without affecting the function of the shoulder joint.

  8. Modern management of complex open abdominal wounds of war: a 5-year experience.

    Vertrees, Amy; Greer, Lauren; Pickett, Chris; Nelson, Jeffery; Wakefield, Matthew; Stojadinovic, Alexander; Shriver, Craig


    Optimal management of the open abdomen remains controversial. Retrospective review of patients injured during Operations Enduring Freedom and Iraqi Freedom returning to Walter Reed Army Medical Center (WRAMC) from January 2003 to October 2007 for treatment of open abdomen. Three hundred fifty-four patients were evacuated to WRAMC after laparotomy, including 86 patients (24%) with open abdomen. Three transferred patients were excluded. Eighty-three patients, mean age 26 years (range 18 to 54 years), sustaining injury from secondary blast (n = 47), gunshot (n = 29), and blunt trauma (n = 7) were studied. Surgical management included early definitive abdominal closure (EDAC, n = 56; 67%), primary fascial closure (n = 15; 18%), planned ventral hernia (PVH, n = 9; 11%) and vacuum-assisted closure with AlloDerm (n = 3; 4%). EDAC closure involves serial closure with Gore-Tex Dualmesh and final closure supplemented with polypropylene mesh (62%) or AlloDerm (31%). There was no substantial difference in injury mechanism, age, length of evacuation to WRAMC, or Injury Severity Score (average 30) according to closure type. Complications included removal of infected prosthetic mesh in 4 EDAC closure patients (5%). Overall morbidity was lowest (60%) in primary repair patients (p = 0.01). Rates of deep venous thrombosis, pulmonary embolism, abdominal wall hematoma, and infection did not differ between groups. Fistula rate was increased with PVH (20%). Two patients with PVH died. PVH and EDAC mesh complications have been minimized in the last 2 years of the study. Primary closure of fascia is ideal but not always possible. Early definitive closure has avoided PVH. Mesh-related complications have decreased with time.

  9. Risk Factors for Wound Complications Following Abdominoplasty

    Samir K. Jabaiti


    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

  10. Case report: management of persistent dural anastomotic dehiscence in a patient treated with bevacizumab.

    Elstner, Kristen E; Clarke, Frederick K; Turner, Scott J


    A 55-year-old woman with recurrent glioblastoma multiforme on palliative chemotherapy including Avastin, an angiogenesis inhibitor, presents with several episodes of bacterial meningitis secondary to a persistent cerebrospinal fluid (CSF) leak. Anastomotic dehiscence of the dura mater in the region of the previous craniotomy sites was evident. Attempts to repair the cranial CSF leak with external ventricular drain and ventriculoperitoneal shunt were unsuccessful. This patient underwent repair of the dural defects with a radial forearm free fascial flap, with consequent resolution of the CSF leak.A literature search was performed, and the available data on angiogenesis inhibitors and anastomotic dehiscence was reviewed, specifically focusing on delayed anastomotic dehiscence in patients receiving Avastin (bevacizumab). Although the potential complications of anastomotic dehiscence in patients receiving angiogenesis inhibitors are well documented, there is comparatively little documentation in the literature regarding delayed wound or anastomotic dehiscence. Twenty such cases were found cited in the literature; however, only one study was found which specifically considered angiogenesis inhibitors within the context of central nervous system malignancies.

  11. Posterior semicircular canal dehiscence: a morphologic cause of vertigo similar to superior semicircular canal dehiscence

    Krombach, G.A.; Schmitz-Rode, T.; Haage, P.; Guenther, R.W. [Department of Diagnostic Radiology, University of Technology, Pauwelstrasse 30, 52057, Aachen (Germany); DiMartino, E.

[Department of Experimental Veterinarian Medicine, University of Technology, Pauwelstrasse 30, 52057, Aachen (Germany)


    Heading Abstract.The aim of this study was to assess imaging findings of posterior semicircular dehiscence on computed tomography and to evaluate incidence of posterior and superior semicircular canal dehiscence in patients presenting with vertigo, sensorineuronal hearing loss or in a control group without symptoms related to the inner ear. Computed tomography was performed in 507 patients presenting either with vertigo (n=128; 23 of these patients suffered also from sensorineuronal hearing loss), other symptoms related to the inner ear, such as hearing loss or tinnitus (n=183) or symptoms unrelated to the labyrinth (n=196). All images were reviewed for presence of dehiscence of the bone, overlying the semicircular canals. Twenty-nine patients had superior semicircular canal dehiscence. Of these patients, 83% presented with vertigo, 10% with hearing loss or tinnitus and the remaining 7% with symptoms unrelated to the inner ear. In 23 patients dehiscence of the posterior semicircular canal was encountered. Of these patients, 86% presented with vertigo, 9% with hearing loss or tinnitus and 5% with symptoms unrelated to the inner ear. Defects of the bony overly are found at the posterior semicircular canal, in addition to the recently introduced superior canal dehiscence syndrome. Significant prevalence of vertigo in these patients suggests that posterior semicircular canal dehiscence can cause vertigo, similar to superior semicircular canal dehiscence. (orig.)

  12. Incisional Negative Pressure Wound Therapy

    Hyldig, Nana; Birke-Sorensen, Hanne; Kruse, Marie;

    Aim: Postoperative wound complications make many surgical procedures unnecessarily complex, particularly in high-risk patients. Negative Pressure Wound Therapy is well recognized in the management of open wounds. In recent years, it has been introduced as well in the management of closed surgical...... incisions to reduce postoperative wound complications, though the evidence base to support this intervention is limited. The aim of this study was to assess if Negative Pressure Wound Therapy (NPWT) reduces postoperative complications when applied on closed surgical incisions. Method: A systematic review...... formation (52%) compared to standard care. The reduction in wound dehiscence was not statistically significant. The numbers needed to treat were 3 (seroma), 17 (dehiscence), and 25 (infection). Methodical heterogeneity across studies led to downgrading quality of evidence to moderate for infection...

    Jurandir Marcondes Ribas-Filho


    increasing, and severity is determined by injury to vital structures in the abdomen and associated injuries. AIM: To identify the causes of abdominal trauma, the most frequently injured digestive viscera, the presence of injuries in other anatomic regions and the relationship of abdominal trauma to sex and age group. METHOD: Thirty-four patients from the Sistema Único de Saúde [the public healthcare system] were selected, all diagnosed with abdominal trauma and seen from January 2005 through September 2005 at the Hospital Universitário Evangélico de Curitiba. Data collection was performed with the aid of a previously formulated protocol. RESULTS: It was found that 91% of the victims were males. The most affected age group was in its third decade of life. Regarding the classification of traumatic injuries, 58.82% presented with open trauma wounds and 41.18% with contusions. Falls accounted for 44 % of contusions, followed by traffic accidents with 35%. The most common open wounds were caused by firearms in 56% of cases and by knives in 44%. Small intestine injury occurred in 31% of the open wounds, followed by liver, colon and kidney injury, with 23% each. In contusions, 60% of the patients sustained spleen injuries. The thorax was the region most frequently associated with abdominal trauma (31%. CONCLUSION: The leading causes of abdominal trauma were gunshot wounds (penetrating trauma and falls (blunt trauma. The most frequently injured viscera in blunt trauma were the parenchymatous ones (spleen and liver, and intestines, liver and kidneys in penetrating trauma. Most patients were males, predominantly in their third decade of life.

  17. Abdominal wall repair with human acellular dermal autograft

    Roel E. Genders


    Full Text Available Repair of abdominal wall defects in the presence of contamination or infection is a significant problem. The loss of tissue warrants enforcement of the abdominal wall, preferably by autologous material. However, autologous repair often requires extensive surgery. This paper presents a review of available literature of placement of an acellular human dermis to repair an abdominal fascia defect, in contaminated as well as in non-contaminated surgical fields. It is illustrated with a case report that describes the successful reconstruction of an infected abdominal wall defect with a human acellular dermis allograft. A systematic literature review was undertaken with searches performed in the Pubmed and Cochrane databases for the period up till March 2009, using the search terms Alloderm [Substance Name], Hernia [Mesh] and the key words acellular dermis, acellular dermal matrix, human acellular dermal allograft and abdominal wall defect. To assess methodological quality, each article was subjected to a modification of the methodological index for non-randomized studies (MINORS according to Slim et al. Two items from the original index were not included because none of the studies selected had an unbiased assessment of the study end points and in none of the studies was a prospective calculation of the study size performed. Seventeen studies were included in the review. Data were extracted regarding study design, number of patients, surgical technique, followup period, contaminated or non-contaminated area of the fascia defect, mortality and morbidity (hemorrhage, seroma, wound dehiscence, infection of the operative procedure, the longterm results (removal of the graft, reherniation and bulging and level of evidencey. A total of 169 short-term complications and 151 longterm complications occurred after 643 surgical procedures reconstructing both contaminated and clean abdominal wall defects by implantation of an HADA.

  18. Double jeopardy revisited: clinical decision making in unstable patients with, thoraco-abdominal stab wounds and, potential injuries in multiple body cavities.

    Clarke, Damian L; Gall, Tamara M H; Thomson, Sandie R


    In the setting of the hypovolaemic patient with a thoraco-abdominal stab wound and potential injuries in both the chest and abdomen, deciding which cavity to explore first may be difficult.Opening the incorrect body cavity can delay control of tamponade or haemorrhage and exacerbate hypothermia and fluid shifts. This situation has been described as one of double jeopardy. All stab victims from July 2007 to July 2009 requiring a thoracotomy and laparotomy at the same operation were identified from a database. Demographics, site and nature of injuries, admission observations and investigations as well as operative sequence were recorded. Correct sequencing was defined as first opening the cavity with most lethal injury. Incorrect sequencing was defined as opening a cavity and finding either no injury or an injury of less severity than a simultaneous injury in the unopened cavity. The primary outcome was survival or death. Sixteen stab victims underwent thoracotomy and laparotomy during the same operation. All were male with an age range of 18–40 (mean/median 27). Median systolic blood pressure on presentation was 90 mm Hg. (quartile range 80–90 mm Hg). Median base excess was 6.5 (quartile range 12 to 2.2). All the deaths were the result of cardiac injuries. Incorrect sequencing occurred in four patients (25%). In this group there were four negative abdominal explorations prior to thoracotomy with two deaths. There was one death in the correct sequencing group. Incorrect sequencing in stab victims who require both thoracotomy and laparotomy at the same sitting is associated with a high mortality. This is especially true when the abdomen is incorrectly entered first whilst the life threatening pathology is in the chest. Clinical signs may be confusing, leading to incorrect sequencing of exploration. The common causes for confusion include failure to appreciate that cardiac tamponade does not present with bleeding and difficulty in assessing peritonism in an

  1. Avaliação fitoterápica da Jatropha gossypiifolia L. na cicatrização de suturas na parede abdominal ventral de ratos Phytotherapic evaluation of Jatropha gossypiifolia L. on rats ventral abdominal wall wound healing

    José Ulcijara Aquino


    L., which is used in popular medicine is considered to have good diuretic effect in hypertension and is also used as a laxative drug. It seems to have a healing effect, although not proved till now. PURPOSE: To evaluate the influence of intraperitoneum administration of Jatropha Gossypiifolia L., in suture healing of ventral abdominal wall of rats, through tensiometric measurement, macro and microscopic aspect of post-operative period. METHODS: Forty wistar male rates were allocated in two groups of 20 animals . After the incision and exposure of abdominal cavity 1 ml/kg/weight of 0,9% sodium chloride solution was injected in control group, and in the other one the injection was of 1 ml/kg/weight of a gross ethanol extract of Jatropha gossypiifolia L. The suture of the abdominal wall was than performed with polypropylene separated stitches. The animals were followed-up and killed in the third and seventh days. The ventral abdominal wall was macroscopically analyzed, the resistance strength to strain was measured and it was also studied the histological aspects. RESULTS: On macroscopic examination more intense adhesion was found on the group of Jatropha in both third and seventh post-operative days. The strain evaluation was meanly greater on Jatropha group also in third and seventh days. CONCLUSION: The histological comparative analysis between the different groups showed that the acute inflammatory process was meanly greater for the Jatropha group in third and seventh post-operative days. The vascular neoformation was significantly greater in third pos-operative day of Jathopha group; the other histological parameters were just alike. The intraperitoneum injection of Jatropha extract did not have any significant improvement for the wound healing on ventral abdominal wall on the evaluated animals in this study, no matter if analyzed at the third or seventh pos-operative days.

  2. Ethylene: Role in Fruit Abscission and Dehiscence Processes 12

    Lipe, John A.; Morgan, Page W.


    Two peaks of ethylene production occur during the development of cotton fruitz (Gossypium hirsutum L.). These periods precede the occurrence of young fruit shedding and mature fruit dehiscence, both of which are abscission phenomena and the latter is generally assumed to be part of the total ripening process. Detailed study of the dehiscence process revealed that ethylene production of individual, attached cotton fruits goes through a rising, cyclic pattern which reaches a maximum prior to dehiscence. With detached pecan fruits (Carya illinoensis [Wang.] K. Koch), ethylene production measured on alternate days rose above 1 microliter per kilogram fresh weight per hour before dehiscence began and reached a peak several days prior to complete dehiscence. Ethylene production by cotton and pecan fruits was measured just prior to dehiscence and then the internal concentration of the gas near the center of the fruit was determined. From these data a ratio of production rate to internal concentration was determined which allowed calculation of the approximate ethylene concentration in the intact fruit prior to dehiscence and selection of appropriate levels to apply to fruits. Ethylene at 10 microliters per liter of air appears to saturate dehiscence of cotton, pecan, and okra (Hibiscus esculentus L.) fruits and the process is completed in 3 to 4 days. In all cases some hastening of dehiscence was observed with as little as 0.1 microliter of exogenous ethylene per liter of air. The time required for response to different levels of ethylene was determined and compared to the time course of ethylene production and dehiscence. We concluded that internal levels of ethylene rose to dehiscence-stimulating levels a sufficience time before dehiscence for the gas to have initiated the process. Since our data and calculations indicate that enough ethylene is made a sufficient time before dehiscence, to account for the process, we propose that ethylene is one of the regulators of

  4. Rejection of Permacol(R) mesh used in abdominal wall repair: A case report

    Franchesca T Wotton; Jacob A Akoh


    Permacol(R) mesh has shown promise when used in abdominal wall repair, especially in the presence of a contaminated surgical field. This biomaterial, derived from porcine dermis collagen, has proposed advantages over synthetic materials due to increased biocompatibility and reduced foreign body reaction within human tissues. However, we present a case report describing a patient who displayed rejection to a Permacol(R) mesh when used in the repair of abdominal wound dehiscence following an emergency laparotomy. Review of the English language literature using PubMed and Medline, showed only two previously published cases of explantation of Permacol(R) due to sepsis or wound breakdown. The authors believe this is the first case of severe foreign body reaction leading to rejection of Permacol(R). Both animal and human studies show conflicting evidence of biocompatibility. There are several reports of successful use of Permacol(R) to repair complex incisional herniae or abdominal walls in the presence of significant contamination. It appears from the literature that Permacol(R) is a promising material, but as we have demonstrated, it has the potential to evoke a foreign body reaction and rejection in certain subjects.

  6. Risk factors for anastomotic dehiscence in colon cancer surgery

    Gessler, Bodil; Bock, David; Pommergaard, Hans-Christian


    PURPOSE: The aim of this was to assess potential risk factors for anastomotic dehiscence in colon cancer surgery in a national cohort. METHODS: All patients, who had undergone a resection of a large bowel segment with an anastomosis between 2008 and 2011, were identified in the Swedish Colon Cancer...... Registry. Patient factors, socioeconomic factors, surgical factors, and medication and hospital data were combined to evaluate risk factors for anastomotic dehiscence. RESULTS: The prevalence of anastomotic dehiscence was 4.3 % (497/11 565). Male sex, ASA classification III-IV, prescribed medications......, bleeding more than 300 mL, and uncommon colorectal resections were associated with a higher risk of anastomotic dehiscence. Hospital stay was increased with 14.5 days, and 30-day mortality as well as long-term mortality was higher in the anastomotic dehiscence group. CONCLUSIONS: There are several factors...

    目的探讨水胶体拉合免缝法在老年患者二期愈合切口中的应用效果.方法 将40例老年腹部手术后二期愈合切口患者随机分为观察组与对照组各20例,于二期愈合切口换药处理至红色期创面后,分别采用水胶体拉合免缝法和传统缝合处理,比较两组切口愈合时间、疼痛程度、换药费用.结果 两组愈合时间比较,差异无统计学意义(P>0.05),但观察组在切口处理过程中的疼痛程度及医疗费用显著低于对照组(均P<0.01).结论 水胶体拉合免缝法应用于老年患者腹部二期愈合切口效果优于传统缝合法,能减轻患者的疼痛,降低医疗费用,且切口更美观.%Objective To reveal effect of hydrocolloid on phase Ⅱ abdominal wound closure without suture for elderly patients.Methods Forty elderly patients with phase Ⅱ abdominal wound were randomly divided into two groups, with 20 cases in each group. When the wound surface became red after dressing change, they were treated either by hydrocolloid for closure without suture (the observation group) or traditional suture (the control group). Wound healing time, degree of pain, and expense of dressing change were compared between the two groups. Results There was no significant difference in wound healing time between the two groups (P>0.05) ; degree of pain during wound dressing and medical expense in the observation group were significantly lower than those in the control group (P<0.01 for both). Conclusion Hydrocolloid used in phase Ⅱ abdominal wound closure without suture for elderly patients is superior to traditional suture, which could relieve pain, decrease medical expense, and make the wound artistic.

  9. Genetic analysis of pod dehiscence in pea (Pisum sativum L.).

    Weeden, Norman F; Brauner, Soren; Przyborowski, Jerzy A


    The inheritance of the dehiscent pod character was investigated in two recombinant inbred populations using a simplified correlation analysis. The approach identified three regions on the pea genome that affect the expression of pod dehiscence. The region on linkage group III corresponded to the expected position of Dpo, a gene known to influence pod dehiscence. A locus on linkage group V appeared to have a slightly smaller effect on expression of the phenotype. The third region was observed only in one cross, had a greater effect than Dpo, and was postulated to be yellow pod allele at the Gp locus

    总结了28例腹腔开放患者自体皮肤移植后的创面护理.分阶段评估植皮后第3天、第7天、第21天的创面恢复情况,采用不同的创面护理措施.对创面合并肠瘘的患者,保持引流的有效性,并采取主动引流,避免肠液侵蚀.同时,做好头部供皮区的护理,加强功能锻炼和心理支持.本组27例患者腹壁创面植皮后第21天,皮片覆盖面积超过90%,只有1例未达90%,经过积极的创面护理,最终创面得到修复.%This paper summarizes the nursing care of abdominal wall wounds for 28 patients with open abdomen after autologous skin transplantation. Targeted wound care was provided for the patients based on the wound assessment at 3 days, 7 days and 21 days after skin transplantation. For patients complicated by intestinal fistula, active drainage was important to avoid corrosion from intestinal fluid. Moreover,nursing care focused on proper nursing of head skin donor site,functional exercises and psychological support. As a result,the covered size of the abdominal wall wounds by blade of thick skin was over 90% in 27 cases at 21 days after skin transplantation. Only one case was under 90%,but healed ultimately after active wound care.

  11. EWMA Document: Negative Pressure Wound Therapy.

    Apelqvist, Jan; Willy, Christian; Fagerdahl, Ann-Mari; Fraccalvieri, Marco; Malmsjö, Malin; Piaggesi, Alberto; Probst, Astrid; Vowden, Peter


    1. Introduction Since its introduction in clinical practice in the early 1990's negative pressure wounds therapy (NPWT) has become widely used in the management of complex wounds in both inpatient and outpatient care.(1) NPWT has been described as a effective treatment for wounds of many different aetiologies(2,3) and suggested as a gold standard for treatment of wounds such as open abdominal wounds,(4-6) dehisced sternal wounds following cardiac surgery(7,8) and as a valuable agent in complex non-healing wounds.(9,10) Increasingly, NPWT is being applied in the primary and home-care setting, where it is described as having the potential to improve the efficacy of wound management and help reduce the reliance on hospital-based care.(11) While the potential of NPWT is promising and the clinical use of the treatment is widespread, highlevel evidence of its effectiveness and economic benefits remain sparse.(12-14) The ongoing controversy regarding high-level evidence in wound care in general is well known. There is a consensus that clinical practice should be evidence-based, which can be difficult to achieve due to confusion about the value of the various approaches to wound management; however, we have to rely on the best available evidence. The need to review wound strategies and treatments in order to reduce the burden of care in an efficient way is urgent. If patients at risk of delayed wound healing are identified earlier and aggressive interventions are taken before the wound deteriorates and complications occur, both patient morbidity and health-care costs can be significantly reduced. There is further a fundamental confusion over the best way to evaluate the effectiveness of interventions in this complex patient population. This is illustrated by reviews of the value of various treatment strategies for non-healing wounds, which have highlighted methodological inconsistencies in primary research. This situation is confounded by differences in the advice given by

  13. Association of body mass index and morbidity after abdominal, vaginal, and laparoscopic hysterectomy.

    Shah, Divya Kelath; Vitonis, Allison F; Missmer, Stacey A


    To examine the association of body mass index (BMI) and operative time and perioperative morbidity after hysterectomy and determine whether the association varies among abdominal, laparoscopic, and vaginal approaches. Data abstracted from the American College of Surgeons National Safety and Quality Improvement Project registry included 55,409 women who underwent hysterectomy for benign conditions between January 2005 and December 2012. The relationships among BMI, operative time, and morbidity were examined, adjusting for age, race, ethnicity, year of surgery, smoking, diabetes, and American Society for Anesthesiologists physical classification. Adjusted means, incidence rate ratios, or odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using linear, Poisson, or logistic regression, respectively. Body mass index was positively correlated with risk of wound complications and infection in women undergoing abdominal hysterectomy. Compared with those of normal BMI, women with BMIs 40 or higher had five times the odds of wound dehiscence (2.1% compared with 0.3%, crude OR 7.35, CI 3.78-14.30; adjusted OR 5.33, CI 2.63-10.8), five times the odds of wound infection (8.9% compared with 1.4%, crude OR 6.81, CI 5.00-9.27; adjusted OR 5.34, CI 3.85-7.41), and 89% higher odds of sepsis (1.3% compared with 0.6%, crude OR 2.39, CI 1.35-4.24; adjusted OR 1.89, CI 1.01-3.52). The magnitude of the association between wound infection and BMI was smaller after vaginal hysterectomy, and no increased odds of wound complications or sepsis were noted with a laparoscopic approach despite longer operative times. Operative time increased with BMI regardless of surgical approach. No associations were noted between BMI and hospital stay or thromboembolism. Obesity is associated with increased wound complications and infection in women undergoing abdominal hysterectomy and with longer operative times regardless of surgical approach. Vaginal or laparoscopic hysterectomy

    Objective: Surgical access to repair a superior canal dehiscence (SCD) is influenced by the location of the bony defect and its relationship to surrounding tegmen topography as seen on computed tomography. There are currently no agreed-upon methods of characterizing these radiologic findings. We

  15. Superior Semicircular Canal Dehiscence Syndrome – Diagnosis and Surgical Management

    Palma Diaz, Marite; Cisneros Lesser, Juan Carlos; Vega Alarcón, Alfredo


    Introduction Superior semicircular canal dehiscence syndrome was described by Minor et al in 1998. It is a troublesome syndrome that results in vertigo and oscillopsia induced by loud sounds or changes in the pressure of the external auditory canal or middle ear. Patients may present with autophony, hyperacusis, pulsatile tinnitus and hearing loss. When symptoms are mild, they are usually managed conservatively, but surgical intervention may be needed for patients with debilitating symptoms. Objective The aim of this manuscript is to review the different surgical techniques used to repair the superior semicircular canal dehiscence. Data Sources PubMed and Ovid-SP databases. Data Synthesis The different approaches are described and discussed, as well as their limitations. We also review the advantages and disadvantages of the plugging, capping and resurfacing techniques to repair the dehiscence. Conclusions Each of the surgical approaches has advantages and disadvantages. The middle fossa approach gives a better view of the dehiscence, but comes with a higher morbidity than the transmastoid approach. Endoscopic assistance may be advantageous during the middle cranial fossa approach for better visualization. The plugging and capping techniques are associated with higher success rates than resurfacing, with no added risk of hearing loss. PMID:28382131

  16. The final split: the regulation of anther dehiscence.

    Wilson, Zoe A; Song, Jie; Taylor, Benjamin; Yang, Caiyun


    Controlling male fertility is an important goal for plant reproduction and selective breeding. Hybrid vigour results in superior growth rates and increased yields of hybrids compared with inbred lines; however, hybrid generation is costly and time consuming. A better understanding of anther development and pollen release will provide effective mechanisms for the control of male fertility and for hybrid generation. Male sterility is associated not only with the lack of viable pollen, but also with the failure of pollen release. In such instances a failure of anther dehiscence has the advantage that viable pollen is produced, which can be used for subsequent rescue of fertility. Anther dehiscence is a multistage process involving localized cellular differentiation and degeneration, combined with changes to the structure and water status of the anther to facilitate complete opening and pollen release. After microspore release the anther endothecium undergoes expansion and deposition of ligno-cellulosic secondary thickening. The septum separating the two locules is then enzymatically lysed and undergoes a programmed cell death-like breakdown. The stomium subsequently splits as a consequence of the stresses associated with pollen swelling and anther dehydration. The physical constraints imposed by the thickening in the endothecium limit expansion, placing additional stress on the anther, so as it dehydrates it opens and the pollen is released. Jasmonic acid has been shown to be a critical signal for dehiscence, although other hormones, particularly auxin, are also involved. The key regulators and physical constraints of anther dehiscence are discussed.

  17. Symptomatic intercostal lung hernia secondary to sternal dehiscence surgery.

    Celik, Sezai; Aydemir, Cüneyt; Gürer, Onur; Işık, Omer


    Patient: Male, 60Final Diagnosis: Iatrogenic intercostal lung herniaSymptoms: -Medication: No medicationClinical Procedure: Surgically cerrectedSpecialty: Thoracic surgery. Unusual clinical course. Iatrogenic intercostal lung hernia is a rare thoracic pathology. Injury of intercostal muscles and costocondral separation during median sternotomy and sternal dehiscence surgery are important factors in the development of hernia. We report for the first time a case of a 60-year-old man with acquired lung hernia after sternal dehiscence surgery, presenting as chest pain and exertional dyspnea. A 60-year-old man presented with a 6-week history of progressive exertional dyspnea, particularly following vigorous coughing. Past medical history included slight chronic obstructive pulmonary disease and coronary artery bypass grafting surgery 8 weeks previously, using the left internal mammary artery for the left anterior descending artery via median sternotomy and sternal dehiscence by the Robicsek method. A chest X-ray showed intact sternal and parasternal wires, but the bilateral lung parenchyma appeared normal. A spiral computed tomography scan of the chest found intercostal herniation of the anterior segment of the left upper lobe. The lung hernia was repaired surgically to relieve exertional dyspnea and incarceration, and to improve respiratory function. The postoperative course was uneventful and the patient recovered well. Intercostal lung hernia after median sternotomy and sternal dehiscence surgery is rare, and it has been previously reported on. Preventive techniques include gentle manipulation of the sternal retractor, avoidance of rib fractures, and using a protective method of intercostal arteries and nerves such as Sharma technique. Thoracic surgeons should be aware of this rare complication in sternal dehiscence surgery.

  18. Effects of prokinetic drugs on the abdominal wall wound healing of rats submitted to segmental colectomy and colonic anastomosis Efeitos de drogas procinéticas na cicatrização da parede abdominal de ratos submetidos à colectomia segmentar e anastomose no cólon esquerdo

    Pedro Henrique Alves de Morais


    Full Text Available PURPOSE: To assess the effect of prokinetic agents on abdominal wall wound healing in rats submitted to segmental colectomy and colonic anastomosis. METHODS: Sixty rats were randomly allocated into three groups according to the agents they would receive in the postoperative period: M (metoclopramide; B (bromopride; and C (control, saline 0.9%. Surgical procedures were performed identically in all animals, and consisted of a midline laparotomy followed by resection of a 1-cm segment of large bowel with end-to-end anastomosis. The abdominal wall was closed in two layers with running stitches. Abdominal wall samples were collected on the 3rd or 7th postoperative day for measurement of breaking (tensile strength and histopathological assessment. RESULTS: There were no statistically significant differences in tensile strength of the abdominal wall scar between groups M, B, and C, nor between the three and seven days after surgery subgroups. On histopathological assessment, there were no statistically significant between-group differences in collagen deposition or number of fibroblasts at the wound site CONCLUSION: Use of the prokinetic drugs metoclopramide or bromopride had no effect on abdominal wall healing in rats submitted to segmental colectomy and colonic anastomosis.OBJETIVO: Avaliar os efeitos do uso de drogas prócinéticas na cicatrização da parede abdominal de ratos submetidos à colectomia segmentar e anastomose no cólon esquerdo. MÉTODOS: Foram utilizados 60 ratos, alocados aleatoriamente em três grupos para receberem as seguintes medicações no período pós-operatório: M (metoclopramida; B (bromoprida e C (solução salina a 0,9%. Os procedimentos cirúrgicos foram idênticos em todos os animais. Foi realizada laparotomia mediana, seguida de colectomia segmentar de 1-cm e anastomose colônica. O fechamento da parede abdominal foi feito em dois planos de sutura contínua. No 3° ou no 7° dia pós-operatório foram coletadas

    Full Text Available The aim of this study was to evaluate the incidence of postoperative wound dehiscence and"ninfection after early closure of evulsive facial wounds. This treatment was conducted on 28 male patients"nwith evulsive facial wounds. The formation of these evulsive wounds was due to the rupture of"ntemporary cavitation caused by high and extra high velocity messiles. All patients with average age of 18"nyears old were treated 24-48 hrs afire accidents at base hospitals (1988-1990."nPrimary healing was achieved in 24 subjects from 7 tO 15 days after the standard operation. Wound"ndehiscences and bacterial infections were observed in 4 subjects."nThe conclusion can be made from the results is that the early closure of evulsive facial wounds may"nreduce the rate of wound dehiscence and infection because of high vascularity in this area.




    Full Text Available Generalized peritonitis following lower segment caesarean section with uterine incision necrosis and dehiscence presenting as genitourinary fistula is very unusual. Herein we report a case of 28 years old woman who was received in emergency hours as a referred case from a private nursing home with history of caesarean section done 11 days back for premature rupture of membranes and pregnancy induced hypertension.

    This animal was presented with a large-sized infiltrative lipoma in the abdominal wall that had been noted for 4 years. This lipoma was confirmed by histological examination from a previous biopsy, and the infiltrative features were identified by a computerized tomography scan. The surgical removal created a large-sized abdominal defect that was closed by a combination of latissimus dorsi and external abdominal oblique muscle flaps in a pedicle pattern. A small dehiscence at the most distal e...

  3. Ethylene: Response of Fruit Dehiscence to CO2 and Reduced Pressure 1

    Lipe, John A.; Morgan, Page W.


    These studies were conducted to determine whether ethylene serves as a natural regulator of fruit wall dehiscence, a major visible feature of ripening in some fruits. We employed treatments to inhibit ethylene action or remove ethylene and observed their effect on fruit dehiscence. CO2 (13%), a competitive inhibitor of ethylene action in many systems, readily delayed dehiscence of detached fruits of cotton (Gossypium hirsutum L.), pecan (Carya illinoensis [Wang.] K. Koch), and okra (Hibiscus esculentus L.). The CO2 effect was duplicated by placing fruits under reduced pressure (200 millimeters mercury), to promote the escape of ethylene from the tissue. Dehiscence of detached fruits of these species as well as attached cotton fruits was delayed. The delay of dehiscence of cotton and okra by both treatments was achieved with fruit harvested at intervals from shortly after anthesis until shortly before natural dehiscence. Pecan fruits would not dehisce until approximately 1 month before natural dehiscence, and during that time, CO2 and reduced pressure delayed dehiscence. CO2 and ethylene were competitive in their effects on cotton fruit dehiscence. All of the results are compatible with a hypothetical role of ethylene as a natural regulator of dehiscence, a dominant aspect of ripening of cotton, pecan, and some other fruits. PMID:16658260

  6. Tullio phenomenon in superior semicircular canal dehiscence syndrome.

    Basura, Gregory J; Cronin, Scott J; Heidenreich, Katherine D


    Tullio phenomenon refers to eye movements induced by sound.(1) This unusual examination finding may be seen in superior semicircular canal dehiscence (SSCD) syndrome.(2) This disorder is due to absent bone over the superior semicircular canal (figure). Patients complain of dizziness triggered by loud sound, aural fullness, autophony, and pulsatile tinnitus. When Tullio phenomenon exists in SSCD syndrome, the patient develops a mixed vertical-torsional nystagmus in which the slow phase rotates up and away from the affected ear (video on the Neurology® Web site at This pattern of nystagmus aligns in the plane of the dehiscent semicircular canal and is due to excitation of its afferent nerves.

  7. Carotid artery protrusion and dehiscence in patients with acromegaly.

    Sasagawa, Yasuo; Tachibana, Osamu; Doai, Mariko; Hayashi, Yasuhiko; Tonami, Hisao; Iizuka, Hideaki; Nakada, Mitsutoshi


    Acromegaly is a systemic disease which causes multiple bony alterations. Some authors reported that acromegalic patients have risk factors for an intraoperative vascular injury due to the specific anatomical features of their sphenoid sinus. The objective of our study was to analyze the anatomic characteristics of sphenoid sinus in acromegalic patients compared with controls, by evaluation of computed tomography (CT) findings. We examined 45 acromegalic (acromegaly group) and 45 non-acromegalic patients (control group) with pituitary adenomas who were matched for sex, age, height, tumor size, and cavernous sinus invasion (Knosp grade). Preoperative CT of the pituitary region including the sphenoid sinus was used to evaluate the following anatomic characteristics: type of sphenoid sinus (sellar or pre-sellar/conchal); intrasphenoid septa (non/single or multiple); carotid artery protrusion; carotid artery dehiscence; intercarotid distance. Sixteen acromegalic patients (35.5 %) and 6 controls (13.3 %) had carotid artery protrusion. Additionally, 10 acromegalic patients (22.2 %) and 3 controls (6.6 %) had carotid artery dehiscence. Carotid artery protrusion and dehiscence were more frequent in the acromegaly group than in control group (p = 0.013 and 0.035, respectively). Other anatomic characteristics (type of sphenoid sinus, intrasphenoid septa, and intracarotid distance) showed no significant differences between acromegaly and control groups. Our study suggests that carotid artery protrusion and dehiscence occur more frequently among acromegalic patients, compared with non-acromegalic patients. It is important for surgeons to be aware of these anatomic variations to avoid vital complications, such as carotid injuries, during surgery.

  8. Raman spectroscopy and the spectral correlation index for predicting wound healing outcome: towards in vivo application

    Berger, Adam G.; Crane, Nicole J.; Elster, Eric A.


    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.

  9. Superior Canal Dehiscence Syndrome: Lessons from the First 20 Years

    Bryan K. Ward


    Full Text Available Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone conduction hyperacusis, and pulsatile tinnitus. The initial series of patients were diagnosed based on common symptoms, a physical examination finding of eye movements in the plane of the superior semicircular canal when ear canal pressure or loud tones were applied to the ear, and high-resolution computed tomography imaging demonstrating a dehiscence in the bone over the superior semicircular canal. Research productivity directed at understanding better methods for diagnosing and treating this condition has substantially increased over the last two decades. We now have a sound understanding of the pathophysiology of third mobile window syndromes, higher resolution imaging protocols, and several sensitive and specific diagnostic tests. Furthermore, we have a treatment (surgical occlusion of the superior semicircular canal that has demonstrated efficacy. This review will highlight some of the fundamental insights gained in SCDS, propose diagnostic criteria, and discuss future research directions.

  11. Wound Care.

    Balsa, Ingrid M; Culp, William T N


    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.




    period was between 11-20 hours. Majority of patients (40% were taken for surgery between 11-15 hours of latent period. Associated extra abdominal injuries were found in 61 cases. Apart from routine investigations, abdomen x ray was done in 96 cases. 81 patients under went four quadrant aspiration. 21 patients under went diagnostic peritoneal lavage. DPL was done in patients who had equivocal signs or obscured by adjacent soft tissue injury. Ultrasound of abdomen was done in 62 cases. CT scan was done in 8 cases. CONCLUSION: Road traffic accidents form the most common mode of injury. Males are predominantly affected. A through and repeated clinical examination leads to successful treatment in these patients. Plain X ray abdomen, ultrasound scan, four quadrant aspiration and diagnostic peritoneal lavage are valuable investigations. Multiple organs are usually involved in most of the cases rather than an isolated organ injury. Associated extra abdominal injuries greatly influence the morbidity and mortality. Post-operative complications like wound infection, dehiscence and respiratory complications are common in blunt abdominal trauma. The present study shows a mortality of 16%.

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


    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

  14. [Prevention of the anastomosis dehiscence following low anterior rectal resections].

    Hut'an, M; Lukác, I; Poticný, V


    Authors analyse 106 patients that were operated in their department by Dixon's method, in retrospective study. They analyse indications for operations, lesions distance in rectum, endosonographic and CT findings. Basic principles of the operation technique are adequate blood flow, sufficient colon mobilization and tightness of the anastomosis being supplemented with transanal pertubation. Out of early complications anastomosis dehiscence appeared in 6 patients (e.g. 5.6%) out of which 4 were treated conservatively and 2 were being reoperated on (by axial ileostomia and drainage). In discussion different opinions on preoperative preparation, neoadjuvant therapy, presacral drainage, transanal pertubation and other decompressive techniques are anticipated.

  15. Standard abdominal wound edge protection with surgical dressings vs coverage with a sterile circular polyethylene drape for prevention of surgical site infections (BaFO: study protocol for a randomized controlled trial

    Mihaljevic André L


    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 NCT01181206.

  16. Facial Canal Dehiscence in Patients with Chronic Otitis Surgery

    Ahmet Uluat


    Full Text Available Aim: To examine facial canal status in patients with chronic otitis media (COM surgery and to detect the relation between facial canals dehiscence (FCD with middle ear pathology in these patients. Material and Method: The surgery data of patients who were subjected to tympanoplasty with or without mastoidectomy and radical mastoidectomy due to COM were analyzed retrospectively from January 2006 to December 2012. In addition to demonstrative data of the patients, status of facial canal and preoperative diagnoses of patients, type of the operation performed, status of middle ear, number of surgeries, existence of cholesteatoma, existence of ossicular chain defect, lateral canal defect and dura defect were assessed and the relation thereof with facial canal dehiscence (FCD was analyzed statistically. Results: Seven hundred ninety six patients were included in the study. FCD was detected in 10.05% of the patients. FCD was most frequently observed in the tympanic segment. It was found out that there was a statistically significant relationship of middle ear pathology, cholesteatoma, revision surgery, lateral semicircular canal and ossicular chain defect with FCD. Discussion: COM diagnosed patients may have defect in facial canal according to their preoperative diagnoses, middle ear pathologies, number of operations and ossicular chain defects. These patients should be applied a more careful surgery and closely followed up in postoperative periods.

  17. Postoperative Interleukin-6 Level and Early Detection of Complications After Elective Major Abdominal Surgery.

    Rettig, Thijs C D; Verwijmeren, Lisa; Dijkstra, Ineke M; Boerma, Djamila; van de Garde, Ewoudt M W; Noordzij, Peter G


    To assess the association of systemic inflammation and outcome after major abdominal surgery. Major abdominal surgery carries a high postoperative morbidity and mortality rate. Studies suggest that inflammation is associated with unfavorable outcome. Levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α and the systemic inflammatory response syndrome (SIRS) were assessed in 137 patients undergoing major abdominal surgery. Blood samples were drawn on days 0, 1, 3, and 7, and SIRS was scored during 48 hours after surgery. Primary outcome was a composite of mortality, pneumonia, sepsis, anastomotic dehiscence, wound infection, noncardiac respiratory failure, atrial fibrillation, congestive heart failure, myocardial infarction, and reoperation within 30 days of surgery. An IL-6 level more than 432 pg/mL on day 1 was associated with an increased risk of complications (adjusted odds ratio: 3.3; 95% confidence interval [CI]: 1.3-8.5) and a longer median length of hospital stay (7 vs 12 days, P < 0.001). As a single test, an IL-6 cut-off level of 432 pg/mL on day 1 yielded a specificity of 70% and a sensitivity of 64% for the prediction of complications (area under the curve: 0.67; 95% CI: 0.56-0.77). Levels of CRP started to discriminate from day 3 onward with a specificity of 87% and a sensitivity of 58% for a cut-off level of 203 mg/L (AUC: 0.73; 95% CI: 0.63-0.83). A high IL-6 level on day 1 is associated with postoperative complications. Levels of IL-6 help distinguish between patients at low and high risk for complications before changes in levels of CRP.

  18. Obesity and older age as protective factors for vaginal cuff dehiscence following total hysterectomy.

    Donnellan, Nicole M; Mansuria, Suketu; Aguwa, Nancy; Lum, Deirdre; Meyn, Leslie; Lee, Ted

    Studies have shown an increased risk of vaginal cuff dehiscence following total laparoscopic hysterectomy (TLH). Patient variables associated with dehiscence have not been well described. This study aims to identify factors associated with dehiscence following varying routes of total hysterectomy. This is a retrospective, matched, case-control study of women who underwent a total hysterectomy at a large, urban, university-based teaching hospital from January 2000 to December 2011. Women who underwent a total hysterectomy and had a dehiscence (n = 31) were matched by surgical mode to the next five total hysterectomies (n = 155). Summary statistics and conditional logistic regression were performed to compare cases to controls. Obese women (BMI ≥ 30) were 70 % less likely than normal weight women (BMI hysterectomy route, obese women were 86 % less likely to have a dehiscence following robotic-assisted total hysterectomy (RAH) and TLH than normal weight women (p = 0.04). Further, increasing age was protective of dehiscence in this subgroup of women (p = 0.02). Older age and obesity were associated with a decreased risk of dehiscence following RAH and TLH but not following other routes. Increased risk of dehiscence following TLH observed in previous studies may be partially due to patient characteristics.

  19. Intra-Abdominal Hypertension and Abdominal Compartment Syndrome in Association with Ruptured Abdominal Aortic Aneurysm in the Endovascular Era: Vigilance Remains Critical

    Matthew C. Bozeman


    In this review, we describe published experience with IAH and ACS complicating abdominal vascular catastrophes, experience with ACS complicating endovascular repair of rAAAs, and techniques for management of the abdominal wound. Vigilance and appropriate management of IAH and ACS remains critically important in decreasing morbidity and optimizing survival following catastrophic intra-abdominal vascular events.

    We assessed the value of MRI for delineation of dehiscence of the superior or posterior semicircular canal, as compared with CT, the current standard study for this entity. We reviewed heavily T2-weighted fast spin-echo images and high-resolution CT of the temporal bones of 185 patients independently semicircular canal dehiscence and its extent. In 30 patients (19 men, 11 women) we identified dehiscence of the bone over the superior and/or posterior semicircular canal on MRI. In 27 of these cases CT also showed circumscribed bone defects. In one patient dehiscence of the superior semicircular canal was initially overlooked on MRI, but seen on CT. MRI imaging thus had a sensitivity of 96% and specificity of 98%. Knowledge of the appearances of this entity on MRI may contribute to early diagnosis in patients with vertigo due to semicircular canal dehiscence. (orig.)

  1. Superior semicircular canal dehiscence in East Asian women with osteoporosis

    Yu Alexander


    Full Text Available Abstract Background Superior semicircular canal dehiscence (SSCD may cause Tullio phenomenon (sound-induced vertigo or Hennebert sign (valsalva-induced vertigo due to the absence of bone overlying the SSC. We document a case series of elderly East Asian women with atypical SSCD symptoms, radiologically confirmed dehiscence and concurrent osteoporosis. Methods A retrospective record review was performed on patients with dizziness, vertigo, and/or imbalance from a neurology clinic in a community health center serving the East Asian population in Boston. SSCD was confirmed by multi-detector, high-resolution CT of the temporal bone (with Pöschl and Stenvers reformations and osteoporosis was documented by bone mineral density (BMD scans. Results Of the 496 patients seen in the neurology clinic of a community health center from 2008 to 2010, 76 (17.3% had symptoms of dizziness, vertigo, and/or imbalance. Five (6.6% had confirmed SSCD by multi-detector, high-resolution CT of the temporal bone with longitudinal areas of dehiscence along the long axis of SSC, ranging from 0.4 to 3.0 mm, as seen on the Pöschl view. Two of the 5 patients experienced motion-induced vertigo, two fell due to disequilibrium, and one had chronic dizziness. None had a history of head trauma, otologic surgery, or active intracerebral disease. On neurological examination, two patients had inducible vertigo on Dix-Hallpike maneuver and none experienced cerebellar deficit, Tullio phenomenon, or Hennebert sign. All had documented osteoporosis or osteopenia by BMD scans. Three of them had definite osteoporosis, with T-scores  Conclusions We describe an unusual presentation of SSCD without Tullio phenomenon or Hennebert sign in a population of elderly, East Asian women. There may be an association of SSCD and osteoporosis in this population. Further research is needed to determine the incidence and prevalence of this disorder, as well as the relationship of age, race

  2. Temporal Bone Fracture Causing Superior Semicircular Canal Dehiscence

    Kevin A. Peng


    Full Text Available Importance. Superior semicircular canal dehiscence (SCD is a third window lesion of the inner ear causing symptoms of vertigo, autophony, tinnitus, and hearing loss. A “two-hit” hypothesis has traditionally been proposed, whereby thinly developed bone overlying the superior canal is disrupted by a sudden change in intracranial pressure. Although the symptoms of SCD may be precipitated by head injury, no previous reports have described a temporal bone fracture directly causing SCD. Observations. Two patients sustained temporal bone fractures after closed head trauma, and developed unilateral otologic symptoms consistent with SCD. In each instance, computed tomography imaging revealed fractures extending through the bony roof of the superior semicircular canal. Conclusions and Relevance. Temporal bone fractures, which are largely treated nonoperatively, have not previously been reported to cause SCD. As it is a potentially treatable entity, SCD resulting from temporal bone fracture must be recognized as a possibility and diagnosed promptly if present.

  3. Laparoscopic Repair of Vaginal Evisceration after Abdominal Hysterectomy for Uterine Corpus Cancer: A Case Report and Literature Review.

    Matsuhashi, Tomohiko; Nakanishi, Kazuho; Hamano, Eri; Kamoi, Seiryu; Takeshita, Toshiyuki


    Vaginal cuff dehiscence is a rare but serious complication that can develop after hysterectomy. Emergent surgical intervention is required for vaginal cuff dehiscence due to the potential subsequent vaginal evisceration, which may lead to necrosis of the small bowel. A 62-year-old nulliparous woman with a 30-year history of smoking, diabetes mellitus, and rheumatoid arthritis (treated with oral steroids) presented with a vaginal cuff dehiscence. Thirty-eight days before the admission, she had undergone a radical operation including total abdominal hysterectomy for uterine corpus cancer at another hospital. We performed emergent laparoscopic surgery to reduce the prolapsed small bowel into the abdominal cavity and repaired the vaginal cuff with a two-layer continuous closure using absorbable barbed sutures. The patient experienced no postoperative complications, and no recurrence of the vaginal cuff dehiscence occurred. Vaginal cuff dehiscence and evisceration can be surgically managed using an abdominal, vaginal, or laparoscopic approach, and the choice of method should be based on patient characteristics and the surgeon's skills. Laparoscopic vaginal cuff repair with a two-layer continuous closure using absorbable barbed sutures is a minimally invasive technique that is safe and effective for medically stable patients with no small bowel injury or vascular compromise and no pelvic abscess.

  4. [Dehiscence of the anterior semicircular canal and otosclerosis: a case report].

    Nguyen, D Q; Morel, N; Dumas, G; Boubagra, K; Schmerber, S


    The dehiscence of the anterior semicircular canal is a new clinical entity, it is necessary to consider this when a gusher occurs during stapedial surgery. We report a rare case of dehiscence of the anterior canal associated with otosclerosis. This was revealed by a gusher during the initial stapedectomy. At 3 months, an obliteration of the dehiscence was necessary by middle cranial fossa approach (persistant vestibular symptoms), seven months later. Revision stapedial surgery resulted in complete closure of the air-bone-gap. High resolution CT scans of the temporal bone are the key to diagnosis. It is necessary to appreciate this pathology with advances in canal and vestibular surgery.

  5. A concomitant review of the effects of diabetes mellitus and hypothyroidism in wound healing

    Konstantinos A Ekmektzoglou; Georgios C Zografos


    This paper reviews the negative impact of diabetes mellitus or hypothyroidism on wound healing, both in experimental and clinical settings. Since both are metabolic disorders of great clinical importance, special attention is given, not only to their pathophysiology,but also to their biochemical and histological effects on tissue integrity and regeneration. Also, special focus is awarded on wound healing of the gastrointestinal tract,i.e. in intestinal anastomosis, and how these disorders can lead to wound dehiscence. Since diabetes mellitus and hypothyroidism can coexist in clinical settings, more research must be directed on their influence on wound healing, considering them as one clinical entity.

  6. Influence of surgical sutures on wound healing

    Mirković Siniša


    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.

  7. The effect of superior semicircular canal dehiscence on intracochlear sound pressures.

    Pisano, Dominic V; Niesten, Marlien E F; Merchant, Saumil N; Nakajima, Hideko Heidi


    Semicircular canal dehiscence (SCD) is a pathological opening in the bony wall of the inner ear that can result in conductive hearing loss. The hearing loss is variable across patients, and the precise mechanism and source of variability are not fully understood. Simultaneous measurements of basal intracochlear sound pressures in scala vestibuli (SV) and scala tympani (ST) enable quantification of the differential pressure across the cochlear partition, the stimulus that excites the cochlear partition. We used intracochlear sound pressure measurements in cadaveric preparations to study the effects of SCD size. Sound-induced pressures in SV and ST, as well as stapes velocity and ear canal pressure were measured simultaneously for various sizes of SCD followed by SCD patching. Our results showed that at low frequencies (pressure in both SV and ST, as well as differential pressure, and these effects became more pronounced as dehiscence size was increased. Near 100 Hz, SV decreased by about 10 dB for a 0.5-mm dehiscence and by 20 dB for a 2-mm dehiscence, while ST decreased by about 8 dB for a 0.5-mm dehiscence and by 18 dB for a 2-mm dehiscence. Differential pressure decreased by about 10 dB for a 0.5-mm dehiscence and by about 20 dB for a 2-mm dehiscence at 100 Hz. In some ears, for frequencies above 1 kHz, the smallest pinpoint dehiscence had bigger effects on the differential pressure (10-dB decrease) than larger dehiscences (less than 10-dB decrease), suggesting larger hearing losses in this frequency range. These effects due to SCD were reversible by patching the dehiscence. We also showed that under certain circumstances such as SCD, stapes velocity is not related to how the ear can transduce sound across the cochlear partition because it is not directly related to the differential pressure, emphasizing that certain pathologies cannot be fully assessed by measurements such as stapes velocity.

    Introduction: The main purpose of this study is to determine the radiological incidence of Superior (SSCD) and Posterior Semicircular Canal Dehiscence (PSCD) and to compare radiologic SSCD to the incidence of this condition on cadaver specimen. We have also analysed the relation between the ossification state of the semicircular canals and the degree of mastoid pneumatization and integrity of Tegmen Tympani. Material and methods: Temporal bones have been investigated by means of CT scan on patients and direct observation on cadaver specimen, respectively. Results: 604 ears and 160 cadaver temporal bones have been investigated by means of CT scan and direct observation, respectively. 3.6% and 0.3% of the studied ears had SSCD and PSCD, respectively, on CT scan. Only 0.6% of the cadaver specimen ears did have anatomical SSCD. Degree of pneumatization of the mastoid bone is related to the mean thickness of bone overlying the Superior and Posterior Semicircular Canal. Radiological absence of Tegmen Tympani is more frequent in ears that also have radiologic SSCD. Conclusion: CT scanning gives higher incidence figures of SSCD than anatomical studies, 3.6% vs. 0.6%. We also found a 0.6% incidence of radiological PSCD in the studied ears. There is a direct relation between the degree of ossification of Superior and Posterior Semicircular Canal and certain temporal bone anatomic features: temporal bone pneumatization and absence/presence of Tegmen Tympani or Antri.

    To evaluate the characteristics of sigmoid plate dehiscence (SPD) causing pulsatile tinnitus (PT) on CT arteriography and venography (CTA + V). Thirty PT patients treated successfully with SPD reconstruction were enrolled. Sixty asymptomatic patients were matched. The location, extent, number of SPD cases and concomitant signs, including venous outflow dominance, transverse sinus stenosis, high jugular bulb, temporal bone pneumatization, height of pituitary gland and pituitary fossa, abnormal mastoid emissary vein, were detected and compared using CTA + V. More than one SPD was found on the symptomatic side in 13/30 PT patients (43.3 %). The upper segment of the sigmoid plate was involved in 29/44 SPDs in the vertical direction (65.9 %); the lateral wall was involved in 38/44 SPDs in the horizontal direction (86.4 %). Singular SPD was detected in 3/60 asymptomatic patients (1.67 ± 0.35 mm{sup 2}), less so in PT patients (7.97 ± 5.17 mm{sup 2}). Compared with the control group, ipsilateral venous outflow dominance, high jugular bulb and bilateral transverse sinus stenosis were more common in the PT group, together with deeper pituitary fossa and flatter pituitary glands. SPD causing PT has characteristic CT findings. It may be generated by vascular or intracranial pressure abnormalities and act as a common key to triggering PT's perception. (orig.)

  10. Is there a role of abdominal drainage in primarily repaired perforated peptic ulcers?

    Musharraf Husain


    Full Text Available Objective: To compare the survival and post-op complications following primary closure of perforated peptic ulcer by omental patch technique in 4 groups of patients as follows: two-drain group, one-drain subhepatic group, one-drain pelvic group and no-drain group. Methods: This is a prospective case-controlled clinical study performed in the Jawaharlal Nehru Medical College Hospital, Aligarh Muslim University, Aligarh, India. A total of 114 patients with perforated peptic ulcer who underwent emergency laparotomy with primary closure by omental patch technique were studied in 4 groups as mentioned above. Tube drains were used throughout the study. Results: Mean age of patients was 45±12.7 years (range 15- 75 with M:F ratio of 5:1. Clinical profile of patients matched in the 4 groups. Post-operative fever, vomiting, laparotomy wound infection, wound dehiscence and intraperitoneal collection were significantly lower in the no-drain group as compared to drain groups. There was found no significant difference between the no-drain and drain groups with respect to the post-operative abdominal distension, pain, intraabdominal sepsis, gastro-intestinal leak, adult respiratory distress syndrome and mortality. Drain-related complications were recorded in 36.8% of patients with tube drain(s. Conclusion: Peptic perforation closure with omental patch technique is safe without prophylactic drainage and a high rate of drain-related morbidity negates the concept of the routine drainage after this procedure. One drain placement is as good as the two drain placement and sub-hepatic drain is more useful than the pelvic drain. [J Exp Integr Med 2012; 2(1.000: 47-54

  11. Using vacuum in the treatment of surgical wounds complications

    Drašković Miroljub


    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.

  12. Semicircular canal dehiscence among idiopathic intracranial hypertension patients.

    Kuo, Phoebe; Bagwell, Kenneth A; Mongelluzzo, Gino; Schutt, Christopher A; Malhotra, Ajay; Khokhar, Babar; Kveton, John F


    The cause of superior semicircular canal dehiscence (SSCD) is unknown. Because of a demonstrated association with tegmental defects and obesity, some have suggested idiopathic intracranial hypertension (IIH) could contribute by eroding the bone over the canal and resulting in SSCD. However, an association between IIH and SSCD has not previously been evaluated. Our objective was to evaluate an association between IIH and SSCD. Retrospective cohort. A retrospective study was performed of opening pressures for consecutive patients presenting at a lumbar puncture clinic between August 2012 and October 2015. Imaging for patients who also had thin-sectioned computed tomography (CT) imaging was reviewed for the presence of radiographic SSCD. Association between IIH and SSCD was evaluated using the Student t test and multivariate logistic regression. One hundred twenty-one patients had both a lumbar puncture performed and thin-sectioned CT imaging available, of which 24 patients (19.8%) met the criteria for IIH with an opening pressure >25 cm H2 O. The remaining 97 patients (80.2%) did not have elevated opening pressures and served as the control cohort. None of the 24 patients with IIH had radiographic SSCD, whereas eight of the 97 patients (8.2%) without IIH had radiographic SSCD. The average opening pressure in patients without radiographic SSCD was 20.2 cm H2 O compared to 19.3 cm H2 O in patients with radiographic SSCD (P = .521). In multivariate logistic regression controlling for age, body mass index, gender, and comorbidities (hypertension, diabetes, hyperlipidemia), opening pressure was not a significant predictor of radiographic SSCD. The results of this retrospective pilot study do not suggest an association between IIH and SSCD. 3b Laryngoscope, 2017. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

  14. Abdominal actinomycosis.

    Wagenlehner, F M E; Mohren, B; Naber, K G; Männl, H F K


    Intra-abdominal and extraperitoneal actinomycosis are rare infections, caused by different Actinomyces species. However, they have been diagnosed more frequently in the last ten years. We report three cases of abdominal actinomycosis and a literature review of the last eight years. All three patients were diagnosed by means of histopathologic examination only. In one case, an intrauterine device (IUD) was associated with the infection. Therapy consisted of surgical resection of the inflammatory, infected tissue, and long-term antibiotic therapy. All patients are free of recurrence. Abdominal actinomycosis should be included in the differential diagnosis of an abdominal pathology of insidious onset, especially when an IUD is in place. Even when infection had spread extensively, combined operative and antibiotic therapy cured most of the cases.

  15. Treatment of postoperative lower extremity wounds using human fibroblast-derived dermis: a retrospective analysis.

    Carlson, Russell M; Smith, Nicholas C; Dux, Katherine; Stuck, Rodney M


    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.

  16. Negative Pressure Wound Therapy with Instillation in a Chronic Non-Healing Right Hip Trochanteric Pressure Ulcer

    Broder, Kevin W; Bodor, Richard M


    Complex pressure ulcer wound sites often present with a wide scope of barriers to healing ranging from high colonization of multi-drug-resistant pathogens to tortuous internal anatomy which make the wound recalcitrant to traditional wound care including standard negative pressure wound therapy (NPWT). Negative pressure wound therapy with instillation (NPWTi-d) provides an opportunity to manage and heal wounds with indications not met by standard NPWT such as cavitating wounds with complex undermining and tunneling. In this clinical case report, a patient who presented with a chronic, non-healing Stage IV pressure ulcer underwent a tensor fascia lata flap reconstruction that was complicated by a partial flap-tip nonadherence with associated partial dehiscence of the flap incision that proved unresolvable until application of adjunctive NPWTi-d which allowed the wound to experience a robust rate of granulation, contraction, and closure.

  17. Underreporting of complete uterine rupture and uterine dehiscence in women with previous cesarean section.

    Fogelberg, Maria; Baranov, Anton; Herbst, Andreas; Vikhareva, Olga


    To determine the true incidence of complete uterine rupture and uterine dehiscence among women delivered by cesarean section after a previous cesarean section. Medical records of all women who delivered at University Hospital in Malmö, Sweden, during 2005-2009 (n = 21 420) were retrieved from the electronic patient record system (EPRS). After adjustment for inaccuracies, 716 women who had undergone repeat cesarean section were identified and their operation reports were reviewed. Descriptions of complete uterine rupture or uterine dehiscence in operation reports were compared with diagnoses registered in EPRS with International Classification of Diseases codes version 10 (ICD-10). Sensitivity and specificity of complete uterine rupture registration were calculated. There were 13 women with a registered diagnosis of uterine rupture. After reviewing medical records of women with repeat cesarean section, seven additional cases of complete uterine rupture, 33 cases of uterine dehiscence and 39 cases of extremely thin myometrium were identified. The incidence of complete uterine rupture and uterine dehiscence for women who delivered by repeat cesarean section was 2.8% and 10.1%, respectively. Diagnosis of complete uterine rupture was underreported in the EPRS by 35% and diagnosis of uterine dehiscence was missing in 100% of cases.

  18. Abdominal Sepsis.

    De Waele, Jan J


    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

  19. Aquaporins of the PIP2 Class Are Required for Efficient Anther Dehiscence in Tobacco

    Bots, Marc; Vergeldt, Frank; Wolters-Arts, Mieke; Weterings, Koen; van As, Henk; Mariani, Celestina


    Several processes during sexual reproduction in higher plants involve the movement of water between cells or tissues. Before flower anthesis, anther and pollen dehydration takes place before the release of mature pollen at dehiscence. Aquaporins represent a class of proteins that mediates the movement of water over cellular membranes. Aquaporins of the plasmamembrane PIP2 family are expressed in tobacco (Nicotiana tabacum) anthers and may therefore be involved in the movement of water in this organ. To gain more insight into the role these proteins may play in this process, we have analyzed their localization using immunolocalizations and generated plants displaying RNA interference of PIP2 aquaporins. Our results indicate that PIP2 protein expression is modulated during anther development. Furthermore, in tobacco PIP2 RNA interference plants, anther dehydration was slower, and dehiscence occurred later when compared with control plants. Together, our results suggest that aquaporins of the PIP2 class are required for efficient anther dehydration prior to dehiscence. PMID:15734911

  1. Vibrational spectroscopy: a tool being developed for the noninvasive monitoring of wound healing

    Crane, Nicole J.; Elster, Eric A.


    Wound care and management accounted for over 1.8 million hospital discharges in 2009. The complex nature of wound physiology involves hundreds of overlapping processes that we have only begun to understand over the past three decades. The management of wounds remains a significant challenge for inexperienced clinicians. The ensuing inflammatory response ultimately dictates the pace of wound healing and tissue regeneration. Consequently, the eventual timing of wound closure or definitive coverage is often subjective. Some wounds fail to close, or dehisce, despite the use and application of novel wound-specific treatment modalities. An understanding of the molecular environment of acute and chronic wounds throughout the wound-healing process can provide valuable insight into the mechanisms associated with the patient's outcome. Pathologic alterations of wounds are accompanied by fundamental changes in the molecular environment that can be analyzed by vibrational spectroscopy. Vibrational spectroscopy, specifically Raman and Fourier transform infrared spectroscopy, offers the capability to accurately detect and identify the various molecules that compose the extracellular matrix during wound healing in their native state. The identified changes might provide the objective markers of wound healing, which can then be integrated with clinical characteristics to guide the management of wounds.

  2. Superior canal dehiscence in a patient with three failed stapedectomy operations for otosclerosis: a case report

    Sudhoff Holger H


    Full Text Available Abstract Introduction This case illustrates that superior semicircular canal dehiscence syndrome can be associated with a "pseudo"-conductive hearing loss, a symptom that overlaps with the clinical appearance of otosclerosis. Case presentation We present the case of a 48-year-old German Caucasian woman presenting with hearing loss on the left side and vertigo. She had undergone three previous stapedectomies for hearing improvement. Reformatted high-resolution computed tomographic scanning and the patient's history confirmed the diagnosis of concurrent canal dehiscence syndrome. Conclusion Failure of hearing improvement after otosclerosis surgery may indicate an alternative underlying diagnosis which should be explored by further appropriate evaluation.

  7. [Wound healing and wound dressing].

    Eitel, F; Sklarek, J


    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

  9. Computerized Assessment of Superior Semicircular Canal Dehiscence Size using Advanced Morphological Imaging Operators.

    Beckett, Joel S; Lagman, Carlito; Chung, Lawrance K; Bui, Timothy T; Lee, Seung J; Voth, Brittany L; Gaonkar, Bilwaj; Gopen, Quinton; Yang, Isaac


    Superior semicircular canal dehiscence (SSCD) describes a pathological aperture at the level of the arcuate eminence. Techniques for quantifying defect size are described with most studies using two-dimensional lengths that underestimate the pathology. The objective of this study is to describe a novel method of measurement that combines manual segmentation of high-resolution computed tomography (HRCT) images of the temporal bone and a morphological skeletonization transform to calculate dehiscence volume. Images were imported into a freely available image segmentation tool: ITK-SNAP (version 3.4.0; available at: software. Coronal and sagittal planes were used to outline the dehiscence in all slices demonstrating the defect using the paintbrush tool. A morphological skeletonization transform derived a single-pixel thick representation of the original delineation. This "sheet" of voxels overlaid the dehiscence. Volume was calculated by counting the number of nonzero image voxels within this "sheet" and multiplying this number by the volume (mm(3)) of each voxel. A total of 70 cases of SSCD were identified. Overall, mean volume was 0.88 mm(3) (standard deviation: 0.57, range: 0.11-2.27). We present a novel technique for measuring SSCD, which we believe provides a more accurate representation of the pathology, and has the potential to standardize measurement of SSCD.

  12. Three-dimensional vibration-induced vestibulo-ocular reflex identifies vertical semicircular canal dehiscence.

    Aw, Swee Tin; Aw, Grace Elizabeth; Todd, Michael John; Bradshaw, Andrew Philip; Halmagyi, Gabor Michael


    Vertical semicircular canal dehiscence (VSCD) due to superior canal dehiscence (SCD) or posterior canal dehiscence (PCD) of the temporal bone causes vestibular and cochlear hypersensitivity to sound. This study aimed to characterize the vibration-induced vestibulo-ocular reflex (ViVOR) in VSCD. ViVORs in one PCD and 17 SCD patients, confirmed by CT imaging reformatted in semicircular canal planes, were measured with dual-search coils as binocular three-dimensional eye rotations induced by skull vibrations from a bone oscillator (B71-10 ohms) at 7 ms, 500 Hz, 135-dB peak-force level (re: 1 μN). The ViVOR eye rotation axes were computed by vector analysis and referenced to known semicircular canal planes. Onset latency of the ViVOR was 11 ms. ViVOR from VSCD was up to nine times greater than normal. The ViVOR's torsional rotation was always contraversive-torsional (the eye's upper pole rotated away from the stimulated ear), i.e. its direction was clockwise from a left and counterclockwise from a right VSCD, thereby lateralizing the side of the VSCD. The ViVORs vertical component distinguishes PCD from SCD, being downwards in PCD and upwards in SCD. In unilateral VSCD, the ViVOR eye rotation axis aligned closest to the dehiscent vertical semicircular canal axis from either ipsilateral or contralateral mastoid vibrations. However, in bilateral VSCDs, the ViVOR eye rotation axis lateralized to the ipsilateral dehiscent vertical semicircular canal axis. ViVOR was evoked in ossicular chain dysfunction, even when air-conducted click vestibulo-ocular reflex (VOR) was absent or markedly reduced. Hence, ViVOR could be a useful measurement to identify unilateral or bilateral VSCD even in the presence of ossicular chain dysfunction.

  13. Enhancement of Seed Dehiscence by Seed Treatment with Talaromyces flavus GG01 and GG04 in Ginseng (Panax ginseng)

    Kim, Min-Jeong; Shim, Chang-Ki; Kim, Yong-Ki; Hong, Sung-Jun; Park, Jong-Ho; Han, Eun-Jung; Kim, Seok-Cheol


    Seed dehiscence of ginseng (Panax ginseng C. A. Mayer) is affected by moisture, temperature, storage conditions and microbes. Several microbes were isolated from completely dehisced seed coat of ginseng cultivars, Chunpoong and Younpoong at Gumsan, Korea. We investigated the potential of five Talaromyces flavus isolates from the dehiscence of ginseng seed in four traditional stratification facilities. The isolates showed antagonistic activities against fungal plant pathogens, such as Cylindrocarpon destructans, Fusarium oxysporum, Rhizoctonia solani, Sclerotinia nivalis, Botrytis cinerea, and Phytophthora capsici. The dehiscence ratios of ginseng seed increased more than 33% by treatment of T. flavus GG01, GG02, GG04, GG12, and GG23 in comparison to control (28%). Among the treatments, the reformulating treatment of T. flavus isolates GG01 and GG04 showed the highest of stratification ratio of ginseng seed. After 16 weeks, the reformulating treatment of T. flavus isolates GG01 and GG04 significantly enhanced dehiscence of ginseng seed by about 81% compared to the untreated control. The candidate’s treatment of T. flavus GG01 and GG04 showed the highest decreasing rate of 93% in seed coat hardness for 112 days in dehiscence period. The results suggested that the pre-inoculation of T. flavus GG01 and GG04 found to be very effective applications in improving dehiscence and germination of ginseng seed. PMID:28167883

  14. Pectoralis myocutaneous flap for salvage of necrotic wounds

    Price, J.C.; Davis, R.K.; Koltai, P.J.


    The authors have utilized six pectoralis major myocutaneous flaps in attempts to salvage extensive necrotic wounds of the pharynx and neck. The flap was employed in the following situations: massive necrosis of the entire neck skin with both carotid artery systems exposed, radiation necrosis of the neck skin with exposure of carotid artery, dehiscence of gastric pull-up from pharynx with resultant carotid exposure, failed trapezius flap in a radionecrotic oral cavity, and two cases of pharyngocutaneous fistula with extensive soft tissue necrosis. These flaps achieved healing in all cases. One death occurred 3 weeks following complete cutaneous healing secondary to a ruptured carotid pseudoaneurysm. One flap underwent total skin loss but the entirety of the muscle survived and the fistula was successfully closed with the back of the muscle being subsequently skin grafted. One case of dehiscence of the flap from oral mucosa resulted in a minor exposure of mandible with limited osteoradionecrosis controlled by topical means. This flap has performed extremely well in these precarious and difficult situations that previously may not have been salvageable. It has also been effective in abbreviating the required hospitalization and wound care. The authors conclude that the pectoralis myocutaneous flap should be the primary choice for the management of extensive postsurgical wound necrosis.

  15. An unusual stab wound to the buttock

    Ashraf F Hefny


    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.

  16. Wound Disruption after Lower Extremity Bypass Surgery is a Predictor of Subsequent Development of Wound Infection.

    Aziz, Faisal; Bohr, Tiffany; Lehman, Erik B


    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

  17. Complicated sternal dehiscence treated with the strasbourg thoracic osteosyntheses system (STRATOS and the transposition of greater omentum: a case report

    Casablanca Giuseppe


    Full Text Available Abstract Sternal dehiscence is a serious complication after cardiac surgery. Sternal refixation, performed by simple rewiring or techniqual modification of rewiring as described by Robicsek, can fail, overall when the bone quality is poor or the sternum is completely destroyed. The sternal closure systems, consisting of plates, screws or rib clips and titanium bars, have been recently introduced to treat the complicated sternal dehiscence. We describe for the first time the use of the Strasbourg Thoracic Osteosyntheses System (STRATOS and the greater omentum, to treat a complicated sternal dehiscence, causing chest pain and respiratory failure.

    FANG Guo-en; LUO Tian-hang; DU Cheng-hui; BI Jian-wei; XUE Xu-chao; WEI Guo; WENG Zhao-zhang; MA Li-ye; HUA Ji-de


    Objective: To improve the prognosis of patients with abdominal trauma. Methods: Between January 1993 and December 2005, 415 patients were enrolled in this research. The patients consisted of 347 males and 68 females with mean age of 36 years ranging from 3-82 years. All abdominal traumas consisted of closed traumas 360 cases, 86.7% and open traumas 55 cases, 13.3%. Results: Atotal of 407 cases 98.1% were fully recovered from trauma and the other 8 cases 1.9% died of multiple injuries. The mean injury severity score ISS of all patients was 22 while the mean ISS of the patients who died in hospital was 42. Postoperative complications were seen in 9 patients such as infection of incisional wounds 6 cases, pancreatic fistula 2 cases and intestinal fistula 1 case. All these postoperative complications were cured by the conservative treatment. Conclusion: Careful case history inquisition and physical examination are the basic methods to diagnose abdomi- nal trauma. Focused abdominal ultrasonography is always the initial imaging examination because it is non-invasive and can be performed repeatedly with high accuracy. The doctors should consider the severity of local injuries and the general status of patients during the assessment of abdominal trauma. The principle of treatment is to save lives at first, then to cure the injuries. Unnecessary laparotomy should be avoided to reduce additional surgical trauma.

    Carolina Giordani Silva


    .The aim of this study was to identify the dressings used to treat abdominal surgical wounds with complications, in order to look for evidence that supports the development of an institutional protocol for handling these wounds. Methodology: a Systematic Review was developed, which had as a guiding question: What is the prevalent dressing in the treatment of patients with complications in abdominal surgical wounds? The MeSH database was used to search for the largest possible number of studies in seven electronic databases. Results: The search in the databases resulted in 6,107 articles, after being tested for relevance, the result was 33 studies that comprised the sample. The use of the VAC dressing was the best suited to treat abdominal surgical wounds with complications. Conclusion: Further research is suggested, so that the effectiveness and feasibility of VAC therapy in our reality can be assessed.

  3. Three-Dimensional Printed Prosthesis for Repair of Superior Canal Dehiscence.

    Kozin, Elliott D; Remenschneider, Aaron K; Cheng, Song; Nakajima, Hideko Heidi; Lee, Daniel J


    Outcomes following repair of superior canal dehiscence (SCD) are variable, and surgery carries a risk of persistent or recurrent SCD symptoms, as well as a risk of hearing loss and vestibulopathy. Poor outcomes may occur from inadequate repair of the SCD or mechanical insult to the membranous labyrinth. Repair of SCD using a customized, fixed-length prosthesis may address current operative limitations and improve surgical outcomes. We aim to 3-dimensionally print customized prostheses to resurface or occlude bony SCD defects. Dehiscences were created along the arcuate eminence of superior semicircular canals in cadaveric temporal bones. Prostheses were designed and created using computed tomography and a 3-dimensional printer. The prostheses occupied the superior semicircular canal defect, reflected in postrepair computed tomography scans. This novel approach to SCD repair could have advantages over current techniques. Refinement of prosthesis design and materials will be important if this approach is translated into clinical use.

    Iris Soberón Varela


    such wounds. In present paper authors showed the results of colonic primary suture in penetrating abdominal wounds in patients seen by a surgery working basic team from the "Joaquín Albarrán Domínguez" Clinical Surgical Hospital (La Habana. METHODS. A prospective study was performed in all patients presenting with abdominal penetrating wounds and colonic lesions who underwent colon primary suture seen by our working basic team between January, 2005 and May, 2008. The exclusion criteria included only the hypovolemic shock status, delay for more than 6 hours from the moment of lesion and surgery as well as the severe fecal contamination. RESULTS. During the above period 17 male patients aged 16 and 43 were operated on the 76,4% with associated intra-abdominal lesions. The causal agent of wound was a steel in the 100% of cases. Left colon was the more involved site (53%. The 100% of patients received antibiotics and the more used were third-generation cephalosporins associated always with the Metrodinazole. There were re-surgical interventions without dehiscence suture. No death occurred and man stay was of 6,9 days. CONCLUSIONS. The suture of colonic wounds produced by steel safe even though these be located in the left colon and there are lesions associated with other organs.

  5. Characterization and mapping of a new male sterility mutant of anther advanced dehiscence (t) in rice

    Yi Zhang; Yunfeng Li; Jian Zhang; Fucheng Shen; Yuanxin Huang; Zhiwei Wu


    Anther dehiscence is very important for pollen maturation and release.The mutants of anther dehiscence in rice (Oryza sativa L.) arefew,and related research remains poor.A male sterility mutant of anther dehiscence in advance,add(t),has been found in Minghui 63 and its sterility is not sensitive to thermo-photo.To learn the character of sterilization and the function of the add(t) gene,the morphological and cytological studies on the anther and pollen,the ability of the pistil being fertilized,inheritance of the mutant,and mapping of add(t)gene have been conducted.The anther size is normal but the color is white in the mutant against the natural yellow in the wild-type.The pollen is malformed,unstained,and small in the KI-I2 solution.The anther dehiscence is in advance at the bicellular pollen stage.A crossing test indicated that the grain setting ratio of the add(t) is significantly lower than that of the CMS line 2085A.The ability of the pistil being fertilized is most probably decreased by the add(t) gene.The male sterility is controlled by a single recessive gene of add(t).This gene is mapped between the markers of R02004 (InDel) and RM300 (SSR) on chromosome 2,and the genetic distance from the add(t) gene to these markers is 0.78 cM and 4.66 cM,respectively.

  6. Minimizing incisional dehiscence following 2-stage prosthetic breast reconstruction in the setting of radiation therapy

    Nahabedian, Maurice Y.


    Incisional dehiscence is a potential complication following prosthetic breast reconstruction. This is exacerbated in the setting of previous radiation therapy (RT) at the time of exchange of the tissue expander to a permanent implant. A technical modification is described that has successfully minimized this adverse event. Twenty-nine patients that had tissue expanders and RT underwent exchange of the device through a laterally based incision along the inframammary fold (IMF) rather than thro...

  7. Superior semicircular canal dehiscence associated with external, middle, and inner ear abnormalities.

    Wang, Jenny R; Parnes, Lorne S


    We report a case of bilateral superior semicircular canal dehiscence (SSCD) in a 38-year-old man who presented with congenital hearing loss without vestibular symptoms. This case is unusual due to the association of SSCD with multiple congenital anomalies of the external, middle, and inner ears, but without any other craniofacial or systemic developmental anomalies. Findings of multiple malformations of temporal bone structures in this case lend support to the theory that SSCD may have an underlying developmental or congenital etiology.

Considering the chemical and physical properties as well as the function of the dressings, standardized dressing techniques can be performed with relatively few materials. This saves both time and money.

  9. Ricinosomes predict programmed cell death leading to anther dehiscence in tomato.

    Senatore, Adriano; Trobacher, Christopher P; Greenwood, John S


    Successful development and dehiscence of the anther and release of pollen are dependent upon the programmed cell death (PCD) of the tapetum and other sporophytic tissues. Ultrastructural examination of the developing and dehiscing anther of tomato (Solanum lycopersicum) revealed that cells of the interlocular septum, the connective tissue, the middle layer/endothecium, and the epidermal cells surrounding the stomium all exhibit features consistent with progression through PCD. Ricinosomes, a subset of precursor protease vesicles that are unique to some incidents of plant PCD, were also present in all of these cell types. These novel organelles are known to harbor KDEL-tailed cysteine proteinases that act in the final stages of corpse processing following cell death. Indeed, a tomato KDEL-tailed cysteine proteinase, SlCysEP, was identified and its gene was cloned, sequenced, and characterized. SlCysEP transcript and protein were restricted to the anthers of the senescing tomato flower. Present in the interlocular septum and in the epidermal cells surrounding the stomium relatively early in development, SlCysEP accumulates later in the sporophytic tissues surrounding the locules as dehiscence ensues. At the ultrastuctural level, immunogold labeling localized SlCysEP to the ricinosomes within the cells of these tissues, but not in the tapetum. It is suggested that the accumulation of SlCysEP and the appearance of ricinosomes act as very early predictors of cell death in the tomato anther.

  10. Risk analysis and outcome of mediastinal wound and deep mediastinal wound infections with specific emphasis to omental transposition

    Parissis, Haralabos


    Abstract Background To report our experience, with Deep mediastinal wound infections (DMWI). Emphasis was given to the management of deep infections with omental flaps Methods From February 2000 to October 2007, out of 3896 cardiac surgery patients (prospective data collection) 120 pts (3.02%) developed sternal wound infections. There were 104 males & 16 females; (73.7%) CABG, (13.5%) Valves & (9.32%) CABG and Valve. Results Superficial sternal wound infection detected in 68 patients (1.75%) and fifty-two patients (1.34%) developed DMWI. The incremental risk factors for development of DMWI were: Diabetes (OR = 3.62, CI = 1.2-10.98), Pre Op Creatinine > 200 μmol\\/l (OR = 3.33, CI = 1.14-9.7) and Prolong ventilation (OR = 4.16, CI = 1.73-9.98). Overall mortality for the DMWI was 9.3% and the specific mortality of the omental flap group was 8.3%. 19% of the "DMWI group", developed complications: hematoma 6%, partial flap loss 3.0%, wound dehiscence 5.3%. Mean Hospital Stay: 59 ± 21.5 days. Conclusion Post cardiac surgery sternal wound complications remain challenging. The role of multidisciplinary approach is fundamental, as is the importance of an aggressive early wound exploration especially for deep sternal infections.

  11. The Study of Wound Infection Rate Due to Midsternatomy after Heart Surgeries

    R. Safiarian


    Full Text Available Introduction & Objective: Sternal wound infection and dehiscence are feared complications observed in 0.4-5% of cardiac operations. Even nowadays the mortality remains as high as 20-40%. The aim of the current study was to determine the rate of sternal wound infection. Material and Methods: The outcomes of 388 patients undergoing cardiac surgery during a 7 month follow up were analyzed and their risk factors such as obesity, diabetes, cigarette smoking, blood transfusion, renal failure, hypertension, COPD, preoperative ejection fraction, aortic clamping time, and time of cardio pulmonary bypass were evaluated. The data was analyzed by t-test & 2 statistical tests. Results: The present study revealed that 3 patients developed wound infection and dehiscence and its incidence was 0.74% (P=0.042. There was not any significant relationship between wound infection and the other risk factors (P>0.05. Conclusions: Our results indicate that ejection fraction preoperatively is very important in sternal wound infection. (Sci J Hamadan Univ Med Sci 2011;17(4:39-42

  12. Risk Stratification for Major Postoperative Complications in Patients Undergoing Intra-abdominal General Surgery Using Latent Class Analysis.

    Kim, Minjae; Wall, Melanie M; Li, Guohua


    Preoperative risk stratification is a critical element in assessing the risks and benefits of surgery. Prior work has demonstrated that intra-abdominal general surgery patients can be classified based on their comorbidities and risk factors using latent class analysis (LCA), a model-based clustering technique designed to find groups of patients that are similar with respect to characteristics entered into the model. Moreover, the latent risk classes were predictive of 30-day mortality. We evaluated the use of latent risk classes to predict the risk of major postoperative complications. An observational, retrospective cohort of patients undergoing intra-abdominal general surgery in the 2005 to 2010 American College of Surgeons National Surgical Quality Improvement Program was obtained. Known preoperative comorbidity and risk factor data were entered into LCA models to identify the latent risk classes. Complications were defined as: acute kidney injury, acute respiratory failure, cardiac arrest, deep vein thrombosis, myocardial infarction, organ space infection, pneumonia, postoperative bleeding, pulmonary embolism, sepsis/septic shock, stroke, unplanned reintubation, and/or wound dehiscence. Relative risk regression determined the associations between the latent classes and the 30-day complication risks, with adjustments for the surgical procedure. The area under the curve (AUC) of the receiver operator characteristic curve assessed model performance. LCA fit a 9-class model on 466,177 observations. The composite complication risk was 18.4% but varied from 7.7% in the lowest risk class to 56.7% in the highest risk class. After adjusting for procedure, the latent risk classes were significantly associated with complications, with risk ratios (95% confidence intervals) (compared to the class with the average risk) varying from 0.56 (0.54-0.58) in the lowest risk class to 2.15 (2.11-2.20) in the highest risk class, a 4-fold difference.

  13. Bilayered negative-pressure wound therapy preventing leg incision morbidity in coronary artery bypass graft patients

    Yu, Yongchao; Song, Zhigang; Xu, Zhiyun; Ye, Xiaofei; Xue, Chunyu; Li, Junhui; Bi, Hongda


    Abstract Backgrounds: The harvesting of great saphenous veins for coronary artery bypass graft (CABG) patients may result in significant complications, including lymphorrhagia, lymphoedema, incision infection, wound dehiscence, and skin flap necrosis. We investigated the function of a self-designed bilayered negative pressure wound therapy (b-NPWT) for reducing the above-mentioned complications using a clinical randomized controlled trial. Methods: A single-center, pilot randomized controlled trial was conducted. From December 2013 to March 2014, a total of 72 coronary heart disease patients (48 men and 24 women) received CABG therapy, with great saphenous veins were selected as grafts. Patients were equally randomized into a treatment and a control group. After the harvesting of the great saphenous veins and direct closure of the wound with sutures, b-NPWT was used for the thigh incision in the treatment group for 5 days (treatment thigh). Traditional surgical pads were applied to both the shank incisions of the treatment group patients (treatment shank) and the entire incisions of the control group (control thigh, control shank). Postoperative complications were recorded and statistically analyzed based on outcomes of thigh treatment, shank treatment, thigh control, and shank control groups. Results: The incidence rates of early complications, such as lymphorrhagia, lymphoedema, infection, wound dehiscence, and skin flap necrosis, of the vascular donor site in the thigh treatment group was significantly lower than those in the 3 other groups. Conclusions: The self-designed b-NPWT can effectively reduce postoperative complications, such as lymphedema, incision infection, wound dehiscence, and skin flap necrosis, in CABG patients who underwent great saphenous veins harvesting. Trial registration: The unique registration number is NCT02010996. PMID:28099357

  14. Comparative analysis of collagen membranes for the treatment of implant dehiscence defects.

    Oh, Tae-Ju; Meraw, Stephen J; Lee, Eun-Ju; Giannobile, William V; Wang, Hom-Lay


    Guided bone regeneration (GBR) evolved from the concept of guided tissue regeneration (GTR) and has been used for reconstructing sites with bone deficiencies associated with dental implants. For GBR, the use of absorbable collagen membranes has been increasing, but, at present, scientific information on the use of collagen membranes for GBR is limited. This study was aimed to clinically and histomorphometrically compare two collagen membranes, Bio-Gide(R) and BioMend ExtendTM, for the treatment of implant dehiscence defects in eight mongrel dogs. Implant dehiscence defects were surgically created in edentulous ridges, followed by the placement of three endosseous implants bilaterally in the mandible. Each implant dehiscence defect was randomly assigned to one of three treatment groups: (1) control (no membrane), (2) porcine dermis collagen barrier (Bio-Gide) or (3) bovine tendon collagen barrier (BioMend Extend). Dogs were sacrificed at 4 and 16 weeks (four dogs each) after treatment. Histomorphometric analysis included percentage linear bone fill (LF), new bone-to-implant contact (BIC) and area of new bone fill (BF). The results of the study revealed no significant differences among groups for any parameter at 4 weeks. However, at 16 weeks, more LF, BIC, and BF were noted in the membrane-treated groups than controls. BioMend Extend-treated defects demonstrated significantly greater BIC than control (P Membrane exposure occurred in 9 out of 15 sites examined, resulting in significantly less LF and BIC than the sites without membrane exposure (P collagen membranes may significantly enhance bone regeneration, manifested at late stage (16 weeks) of healing; and (2) space maintenance and membrane coverage were the two most important factors affecting GBR using bioabsorbable collagen membranes.

  16. The effect of increased intracranial pressure on vestibular evoked myogenic potentials in superior canal dehiscence syndrome.

    Janky, Kristen L; Zuniga, M Geraldine; Schubert, Michael C; Carey, John P


    To determine if vestibular evoked myogenic potential (VEMP) responses change during inversion in patients with superior canal dehiscence syndrome (SCDS) compared to controls. Sixteen subjects with SCDS (mean: 43, range 30-57 years) and 15 age-matched, healthy subjects (mean: 41, range 22-57 years) completed cervical VEMP (cVEMP) in response to air conduction click stimuli and ocular VEMP (oVEMP) in response to air conduction 500 Hz tone burst stimuli and midline tap stimulation. All VEMP testing was completed in semi-recumbent and inverted conditions. SCDS ears demonstrated significantly larger oVEMP peak-to-peak amplitudes in comparison to normal ears in semi-recumbency. While corrected cVEMP peak-to-peak amplitudes were larger in SCDS ears; this did not reach significance in our sample. Overall, there was not a differential change in o- or cVEMP amplitude with inversion between SCDS and normal subjects. Postural-induced changes in o- and cVEMP responses were measured in the steady state regardless of whether the labyrinth was intact or dehiscent. VEMP responses are blunted during inversion. Although steady-state measurements of VEMPs during inversion do not increase diagnostic accuracy for SCDS, the findings suggest that inversion may provide more general insights into the equilibration of pressures between intracranial and intralabyrinthine fluids.

  17. Functional monoecy due to delayed anther dehiscence: a novel mechanism in Pseuduvaria mulgraveana (Annonaceae).

    Pang, Chun-Chiu; Scharaschkin, Tanya; Su, Yvonne C F; Saunders, Richard M K


    Unlike most genera in the early-divergent angiosperm family Annonaceae, Pseuduvaria exhibits a diversity of floral sex expression. Most species are structurally andromonoecious (or possibly androdioecious), although the hermaphroditic flowers have been inferred to be functionally pistillate, with sterile staminodes. Pseuduvaria presents an ideal model for investigating the evolution of floral sex in early-divergent angiosperms, although detailed empirical studies are currently lacking. The phenology and pollination ecology of the Australian endemic species Pseuduvaria mulgraveana are studied in detail, including evaluations of floral scent chemistry, pollen viability, and floral visitors. Results showed that the flowers are pollinated by small diurnal nitidulid beetles and are protogynous. Pollen from both hermaphroditic and staminate flowers are shown to be equally viable. The structurally hermaphroditic flowers are nevertheless functionally pistillate as anther dehiscence is delayed until after petal abscission and hence after the departure of pollinators. This mechanism to achieve functional unisexuality of flowers has not previously been reported in angiosperms. It is known that protogyny is widespread amongst early-divergent angiosperms, including the Annonaceae, and is effective in preventing autogamy. Delayed anther dehiscence represents a further elaboration of this, and is effective in preventing geitonogamy since very few sexually mature flowers occur simultaneously in an individual. We highlight the necessity for field-based empirical interpretations of functional floral sex expression prior to evaluations of evolutionary processes.

  18. Impaired corneal wound healing associated with ketorolac 0.5% after uncomplicated extracapsular cataract extraction.

    Arey, Mark L; Sullivan, Brian R; Reinert, Carol G; McCulley, James P


    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.

    Lou Xiaoli; Zhang Mingli; Cui Ying; Song Jianxing


    Objective: Uterus-to-abdominal-wall fistula is a very rare complication after uterine-incision delivery over the last decades. It can even lead to death. Mainly, the fistula occurs when big tension and critical infection exist within the incision of uterus and abdominal wall. Methods: The authors described the clinical presentation, pathology of uterus-to-abdominal-wall fistula, and reported their experience in 6 cases who underwent Z-plasty operation for this rare complication from January 1998 to January 2008. Results: All flaps survived completely and all the wounds in abdominal walls healed very well. The six cases were followed up for 1 to 5 years, and no fistula recurrence occurred. Conclusion: Z-plasty technique is a very simple and efficient approach to repair uterus to abdominal fistula after uterine-incision delivery.

    James, Garth A; Swogger, Ellen; Wolcott, Randall; Pulcini, Elinor deLancey; Secor, Patrick; Sestrich, Jennifer; Costerton, John W; Stewart, Philip S


    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.

    Gastric perforation is one of the most serious complications that can occur during endoscopic submucosal dissection (ESD).In terms of the treatment of such perforations,we previously reported that perforations immediately observed and successfully closed with endoclips during endoscopic resection could be managed conservatively.We now report the first case in our medical facility of a gastric perforation during ESD that was ineffectively treated conservatively even after successful endoscopic closure.In December 2006,we performed ESD on a recurrent early gastric cancer in an 81-year-old man with a medical history of laparotomy for cholelithiasis.A perforation occurred during ESD that was immediately observed and successfully closed with endoclips so that ESD could be continued resulting in an en-bloc resection.Intensive conservative management was conducted following ESD,however,an endoscopic examination five days after ESD revealed dehiscence of the perforation requiring an emergency laparotomy.

    To determine whether cervical vestibular evoked myogenic potential (cVEMP) thresholds or ocular VEMP (oVEMP) amplitudes are more sensitive and specific in the diagnosis of superior semicircular canal dehiscence syndrome (SCDS). Prospective case-control study. Tertiary referral center. Twenty-nine patients with SCDS (mean age 48 yr; range, 31-66 yr) and 25 age-matched controls (mean age 48 yr; range, 30-66 yr). cVEMP and oVEMP in response to air-conducted sound. All patients underwent surgery for repair of SCDS. cVEMP thresholds; oVEMP n10 and peak-to-peak amplitudes. cVEMP threshold results showed sensitivity and specificity ranging from 80% to 100% for the diagnosis of SCDS. In contrast, oVEMP amplitudes demonstrated sensitivity and specificity greater than 90%. oVEMP amplitudes are superior to cVEMP thresholds in the diagnosis of SCDS.

    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

  17. Prediction of uterine dehiscence using ultrasonographic parameters of cesarean section scar in the nonpregnant uterus: a prospective observational study.

    Pomorski, Michal; Fuchs, Tomasz; Zimmer, Mariusz


    Every year 1.5 million cesarean section procedures are performed worldwide. As many women decide to get pregnant again, the population of pregnant women with a history of cesarean section is growing rapidly. For these women prediction of cesarean section scar performance is still a serious clinical problem. Starting in 2005, the study included 308 nonpregnant women with a history of low transverse cesarean section. The following ultrasonographic parameters of the cesarean section scar in the nonpregnant uterus were assessed: the residual myometrial thickness (RMT) and the width (W) and the depth (D) of the triangular hypoechoic scar niche. During 8 years of follow-up, 41 of these women were referred to our department for delivery. In all cases, a repeat cesarean section was performed and the lower uterine segment was assessed. Two independent statistical methods namely the logit model and Decision Tree analysis were used to determine the relation between the appearance of the cesarean section scar in the nonpregnat state and the performance of the scar in the next pregnancy. The logit model revealed that the D/RMT ratio showed significant correlation with cesarean section scar dehiscence (P-value of 0.007). Specifically, a D/RMT ratio value greater than 1.3035 indicated that the likelihood of dehiscence was greater than 50%. The Decision Tree analysis revealed that a diagnosis of dehiscence versus non-dehiscence could be based solely on one criterion, a D/RMT ratio of at least 0.785. The sensitivity of this method was 71%, and the specificity was 94%. Assessment of the cesarean section scar in the nonpregant uterus can be used to predict the occurrence of scar dehiscence in the next pregnancy.

  18. Abdominal epilepsy in chronic recurrent abdominal pain

    V Y Kshirsagar


    Full Text Available Background: Abdominal epilepsy (AE is an uncommon cause for chronic recurrent abdominal pain in children and adults. It is characterized by paroxysmal episode of abdominal pain, diverse abdominal complaints, definite electroencephalogram (EEG abnormalities and favorable response to the introduction of anti-epileptic drugs (AED. We studied 150 children with chronic recurrent abdominal pain and after exclusion of more common etiologies for the presenting complaints; workup proceeded with an EEG. We found 111 (74% children with an abnormal EEG and 39 (26% children with normal EEG. All children were subjected to AED (Oxcarbazepine and 139 (92% children responded to AED out of which 111 (74% children had an abnormal EEG and 27 (18% had a normal EEG. On further follow-up the patients were symptom free, which helped us to confirm the clinical diagnosis. Context: Recurrent chronic abdominal pain is a common problem encountered by pediatricians. Variety of investigations are done to come to a diagnosis but a cause is rarely found. In such children diagnosis of AE should be considered and an EEG will confirm the diagnosis and treated with AED. Aims: To find the incidence of AE in children presenting with chronic recurrent abdominal pain and to correlate EEG findings and their clinical response to empirical AEDs in both cases and control. Settings and Design: Krishna Institute of Medical Sciences University, Karad, Maharashtra, India. Prospective analytical study. Materials and Methods: A total of 150 children with chronic recurrent abdominal pain were studied by investigations to rule out common causes of abdominal pain and an EEG. All children were then started with AED oxycarbamezepine and their response to the treatment was noted. Results: 111 (74% of the total 150 children showed a positive EEG change suggestive of epileptogenic activity and of which 75 (67.56% were females and 36 (32.43% were male, majority of children were in the age of group of 9

  19. [Gunshot wounds: forensic pathology].

    Lorin de la Grandmaison, Geoffroy


    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.

  1. Abdominal Decompression in Children

    J. Chiaka Ejike


    Full Text Available Abdominal compartment syndrome (ACS increases the risk for mortality in critically ill children. It occurs in association with a wide variety of medical and surgical diagnoses. Management of ACS involves recognizing the development of intra-abdominal hypertension (IAH by intra-abdominal pressure (IAP monitoring, treating the underlying cause, and preventing progression to ACS by lowering IAP. When ACS is already present, supporting dysfunctional organs and decreasing IAP to prevent new organ involvement become an additional focus of therapy. Medical management strategies to achieve these goals should be employed but when medical management fails, timely abdominal decompression is essential to reduce the risk of mortality. A literature review was performed to understand the role and outcomes of abdominal decompression among children with ACS. Abdominal decompression appears to have a positive effect on patient survival. However, prospective randomized studies are needed to fully understand the indications and impact of these therapies on survival in children.

    Gravity of abdominal vessels traumatisms is secondary to multiple factors. It depends on the type of injured vessels, aetiology and associated lesions. Between September 1984 and March 1995, 22 abdominal vessel traumatisms in 16 patients (mean age: 39 years) were treated. At surgical exploration, 4 aortic and 2 renal vein lesions, 7 iliac artery and 3 renal artery contusions, 2 superior mesenteric artery dissections; 3 infra-renal vena cava ruptures and 1 superior mesenteric vein dilaceration were found. All lesions were caused by penetrant wounds secondary to firearm or blade injury or secondary to injuries due to ski or traffic accidents. In 5 cases, lesions were iatrogenic. There was no mortality in the post-operative period, 14 patients out of the 16 patients operated on have been followed during a period from 1 to 120 months.

    Objective: A retrospective study to determine the success and complications of abdominal sacral colpopexy in correcting massive genital prolapse over an 8-year period between September 1989 and January 1997.Methods: The charts were reviewed for 3 patients with massive procidentia and 15 patients with symptomatic posthysterectomy vaginal vault prolapse, who desired preservation of sexual function and underwent abdominal sacral colpopexy with Marlex mesh at two community teaching hospitals.Results: In 16 of the 18 patients, one or more concurrent procedures were performed at the same time, including three Burch colpocystourethropexies and one Raz bladder neck suspension, which successfully controlled urinary stress incontinence. In three cases, staging procedures were done for ovarian neoplasia. There were no intraoperative complications. One patient developed a superficial abdominal wound infection, one patient had a deep venous thrombosis in her left leg 7 days postoperatively, and one patient experienced a 1 cm area of graft erosion 10 months postoperative requiring partial resection. Duration of follow-up has varied from 8 months to 5 years. One patient died 43 months after surgery of unrelated causes. No patients developed recurrent prolapse.Conclusions: Abdominal sacral colpopexy is a successful operation for the correction of prolapse. Serious complications are infrequent. Photographs of the technique and a review of the literature are presented.

  8. [Perioperative pain management for abdominal and thoracic surgery].

    Englbrecht, J S; Pogatzki-Zahn, E M


    Abdominal and thoracic surgical procedures can result in significant acute postoperative pain. Present evidence shows that postoperative pain management remains inadequate especially after "minor" surgical procedures. Various therapeutic options including regional anesthesia techniques and systemic pharmacotherapy are available for effective treatment of postoperative pain. This work summarizes the pathophysiological background of postoperative pain after abdominal and thoracic surgery and discusses the indication, effectiveness, risks, and benefits of the different therapeutic options. Special focus is given to the controversial debate about the indication for epidural analgesia, as well as various alternative therapeutic options, including transversus abdominis plane (TAP) block, paravertebral block (PVB), wound infiltration with local anesthetics, and intravenous lidocaine. In additional, indications and contraindications of nonopioid analgesics after abdominal and thoracic surgery are discussed and recommendations based on scientific evidence and individual risk and benefit analysis are made. All therapeutic options discussed are eligible for clinical use and may contribute to improve postoperative pain outcome after abdominal and thoracic surgical procedures.

  9. Prosthetics and Techniques in Repair of Animal's Abdominal Wall.

    Karrouf, Gamal; Zaghloul, Adel; Abou-Alsaud, Mohamed; Barbour, Elie; Abouelnasr, Khaled


    The management of abdominal wall repair continues to present a challenging problem, especially in the repair of major defects. Many abdominal wall defects can be repaired by primary closure; however, if the defect is large and there is a tension on the closure of the wound, the use of prosthetic materials becomes indispensable. Many studies have been performed with various materials and implant techniques, without the comparison of their degrees of success, based on sound meta-analysis and/or inclusive epidemiologic studies. This review covered the effectiveness of recent advances in prosthetic materials and implant procedures used in repair of abdominal wall, based on biomechanical properties and economic aspects of reconstructed large abdominal wall defects and hernias in animals. The presented results in this review helped to reach treatment algorithms that could maximize outcomes and minimize morbidity.

  10. Intra-Abdominal Hypertension and Abdominal Compartment Syndrome after Abdominal Wall Reconstruction: Quaternary Syndromes?

    Kirkpatrick, A W; Nickerson, D; Roberts, D J; Rosen, M J; McBeth, P B; Petro, C C; Berrevoet, Frederik; Sugrue, M; Xiao, Jimmy; Ball, C G


    Reconstruction with reconstitution of the container function of the abdominal compartment is increasingly being performed in patients with massive ventral hernia previously deemed inoperable. This situation places patients at great risk of severe intra-abdominal hypertension and abdominal compartment syndrome if organ failure ensues. Intra-abdominal hypertension and especially abdominal compartment syndrome may be devastating systemic complications with systematic and progressive organ failure and death. We thus reviewed the pathophysiology and reported clinical experiences with abnormalities of intra-abdominal pressure in the context of abdominal wall reconstruction. Bibliographic databases (1950-2015), websites, textbooks, and the bibliographies of previously recovered articles for reports or data relating to intra-abdominal pressure, intra-abdominal hypertension, and the abdominal compartment syndrome in relation to ventral, incisional, or abdominal hernia repair or abdominal wall reconstruction. Surgeons should thus consider and carefully measure intra-abdominal pressure and its resultant effects on respiratory parameters and function during abdominal wall reconstruction. The intra-abdominal pressure post-operatively will be a result of the new intra-peritoneal volume and the abdominal wall compliance. Strategies surgeons may utilize to ameliorate intra-abdominal pressure rise after abdominal wall reconstruction including temporizing paralysis of the musculature either temporarily or semi-permanently, pre-operative progressive pneumoperitoneum, permanently removing visceral contents, or surgically releasing the musculature to increase the abdominal container volume. In patients without complicating shock and inflammation, and in whom the abdominal wall anatomy has been so functionally adapted to maximize compliance, intra-abdominal hypertension may be transient and tolerable. Intra-abdominal hypertension/abdominal compartment syndrome in the specific setting of

    Mahgoub, Sara; Gabriele, Victor; Faller, Emilie; Langer, Bruno; Wattiez, Arnaud; Lecointre, Lise; Akladios, Cherif


    stabilisation of HCG to 300 IU/L and the persistence of a residual image next to the cesarean scar, surgical treatment was considered. This video presents a laparoscopic resection of cesarean scar ectopic pregnancy associated with isthmocele repair. Originality of this video is that, for the first time, we illustrate the laparoscopic treatment of total caesarean scar dehiscence. Operative time was 180 minutes. Initially, a hysteroscopic evaluation was realised showing the cesarean scar dehiscence and the posterior pole of the ectopic pregnancy. The second step of the intervention confirms laparoscopically the diagnosis of cesarean scar ectopic pregnancy. Utero-ombilical truncs are bilaterally clamped. Complete enucleation of pregnancy is achieved after dissection of the vesico-uterine peritoneum. Isthmocele treatment is carried out with a closure in two plans. Blue dye test confirms the tightness of the stitches. Utero-ombilical truncs are declamped. Antiadhesion gel is applied next to the new uterine scar. Operation was performed successfully without complication. Intraoperative blood loss was less than 100 mL. The patient was discharged on day 3. No immediate complications were noticed. One month after intervention, US control was normal. Surgical management of caesarean scar ectopic pregnancy with total dehiscence of hysterotomy could be realised safely and efficiently under laparoscopy. Copyright © 2017. Published by Elsevier Inc.

    Bonfante Ramírez, E; Bolaños Ancona, R; Simón Pereyra, L; Juárez García, L; García-Benitez, C Q


    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy.

  18. Wound healing: a new approach to the topical wound care.

    Öztürk, Ferdi; Ermertcan, Aylin Türel


    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.

  19. Abdominal hernias: Radiological features

    Lassandro, Francesco; Iasiello, Francesca; Pizza, Nunzia Luisa; Valente, Tullio; Stefano, Maria Luisa Mangoni di Santo; Grassi, Roberto; Muto, Roberto


    Abdominal wall hernias are common diseases of the abdomen with a global incidence approximately 4%-5%. They are distinguished in external, diaphragmatic and internal hernias on the basis of their localisation. Groin hernias are the most common with a prevalence of 75%, followed by femoral (15%) and umbilical (8%). There is a higher prevalence in males (M:F, 8:1). Diagnosis is usually made on physical examination. However, clinical diagnosis may be difficult, especially in patients with obesity, pain or abdominal wall scarring. In these cases, abdominal imaging may be the first clue to the correct diagnosis and to confirm suspected complications. Different imaging modalities are used: conventional radiographs or barium studies, ultrasonography and Computed Tomography. Imaging modalities can aid in the differential diagnosis of palpable abdominal wall masses and can help to define hernial contents such as fatty tissue, bowel, other organs or fluid. This work focuses on the main radiological findings of abdominal herniations. PMID:21860678

  20. Gastrointestinal causes of abdominal pain.

    Marsicano, Elizabeth; Vuong, Giao Michael; Prather, Charlene M


    Gastrointestinal causes of abdominal pain are numerous. These causes are reviewed in brief here, divided into 2 categories: acute abdominal pain and chronic abdominal pain. They are further subcategorized by location of pain as it pertains to the abdomen.

  1. First evidence of sternal wound biofilm following cardiac surgery.

    Haytham Elgharably

    Full Text Available Management of deep sternal wound infection (SWI, a serious complication after cardiac surgery with high morbidity and mortality incidence, requires invasive procedures such as, debridement with primary closure or myocutaneous flap reconstruction along with use of broad spectrum antibiotics. The purpose of this clinical series is to investigate the presence of biofilm in patients with deep SWI. A biofilm is a complex microbial community in which bacteria attach to a biological or non-biological surface and are embedded in a self-produced extracellular polymeric substance. Biofilm related infections represent a major clinical challenge due to their resistance to both host immune defenses and standard antimicrobial therapies. Candidates for this clinical series were patients scheduled for a debridement procedure of an infected sternal wound after a cardiac surgery. Six patients with SWI were recruited in the study. All cases had marked dehiscence of all layers of the wound down to the sternum with no signs of healing after receiving broad spectrum antibiotics post-surgery. After consenting patients, tissue and/or extracted stainless steel wires were collected during the debridement procedure. Debrided tissues examined by Gram stain showed large aggregations of Gram positive cocci. Immuno-fluorescent staining of the debrided tissues using a specific antibody against staphylococci demonstrated the presence of thick clumps of staphylococci colonizing the wound bed. Evaluation of tissue samples with scanning electron microscope (SEM imaging showed three-dimensional aggregates of these cocci attached to the wound surface. More interestingly, SEM imaging of the extracted wires showed attachment of cocci aggregations to the wire metal surface. These observations along with the clinical presentation of the patients provide the first evidence that supports the presence of biofilm in such cases. Clinical introduction of the biofilm infection concept in deep

  2. Dynamics of parameters of ultrasonic, microbiological and cytological investigations in the treatment of postoperative wound complications using magnesium containing minerals in the elderly patients

    Muntyan S.O.


    Full Text Available 57 patients aged over 60 years with various types of wound complications after surgery for abdominal and anterior abdominal wall were treated. Treatment of wound complications included both traditional methods and the use of packs of bishofit. Оn the third day after the start of treatment there was a significant decrease in almost all computing performance indices as compared with treatment using bishofit. On the day 7 a noticeable difference of wound cavity width by 62.88%, the volume of the wound cavity by 85.76% in patients of the second group as compared with patients of the first was noted. So, bishofit use in the form of compresses in the treatment of postoperative wound complications such as hematoma, seroma and infiltration leads to a significant reduction in wound exudation, rapid decline in the concentration of microorganisms in the wound; this reduces time of wounds healing and patients’ recovery.

  3. Lead poisoning after gunshot wound

    Paulo Roberto de Madureira


    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.

  4. Biofilm in wound care.

    Rajpaul, Kumal


    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.

  5. Periodontal regeneration in experimentally-induced alveolar bone dehiscence by an improved porous biphasic calcium phosphate ceramic in beagle dogs.

    Shi, Han; Ma, Jia; Zhao, Ning; Chen, Yangxi; Liao, Yunmao


    Regeneration of lost periodontium is the focus of periodontal therapy. To achieve the effective regeneration, a number of bone graft substitute materials have been developed. This study aimed to investigate the histological response in alveolar bone dehiscences which were filled with an improved biphasic calcium phosphate (BCP) ceramic with more reasonable pore diameter, pore wall thickness and porosity. Twenty-four alveolar bone dehiscences were made surgically in twelve beagle dogs by reflecting mucoperiosteal flaps on the buccal aspect of bilateral lower second premolars and removing alveolar bone. The left dehiscences were treated with BCP ceramic and the contralaterals were cured with the open flap debridement (OFD) as controls. Three dogs were used at week 4, 12, and 24 respectively. Histological observations were processed through three-dimensional micro-computed tomographic imaging, fluorescence and light microscopy. The histological study indicated that the biphasic ceramic was biocompatible, and regeneration was achieved more effectively through the BCP treatment. There were also arrest of epithelial migration apically and formation of new bone and cementum, as well as proliferation of fibrous connective tissues that became attached to the newly formed cementum at week 24, while there was no significant periodontal regeneration in the OFD group only with epithelial tissue migrating into the dehiscence regions. Clinically speaking, though the surgical location formed a limitation to the application of the improved BCP on the periodontal regeneration, the actual result was positive. It proved that the BCP had biocompatibility and was able to act as a stable scaffold to induce periodontal regeneration effectively.

  6. Carbohydrate metabolism before and after dehiscence in the recalcitrant pollen of pumpkin (Cucurbita pepo L.).

    Carrizo García, C; Guarnieri, M; Pacini, E


    Pumpkin (Cucurbita pepo L.) pollen is starchy, sucrose-poor and recalcitrant, features opposite to those of several model species; therefore, some differences in carbohydrate metabolism could be expected in this species. By studying pumpkin recalcitrant pollen, the objective was to provide new biochemical evidence to improve understanding of how carbohydrate metabolism might be involved in pollen functioning in advanced stages. Four stages were analysed: immature pollen from 1 day before anthesis, mature pollen, mature pollen exposed to the environment for 7 h, and pollen rehydrated in a culture medium. Pollen viability, water and carbohydrate content and activity of enzymes involved in carbohydrate metabolism were quantified in each stage. Pollen viability and water content dropped quickly after dehiscence, as expected. The slight changes in carbohydrate concentration and enzyme activity during pollen maturation contrast with major changes recorded with ageing and rehydration. Pumpkin pollen seems highly active and closely related to its surrounding environment in all the stages analysed; the latter is particularly evident among insoluble sucrolytic enzymes, mainly wall-bound acid invertase, which would be the most relevant for sucrose cleavage. Each stage was characterised by a particular metabolic/enzymatic profile; some particular features, such as the minor changes during maturation, fast sucrolysis upon rehydration or sharp decrease in insoluble sucrolytic activity with ageing seem to be related to the lack of dormancy and recalcitrant nature of pumpkin pollen.

  7. An indicator of probable semicircular canal dehiscence: ocular vestibular evoked myogenic potentials to high frequencies.

    Manzari, Leonardo; Burgess, Ann M; McGarvie, Leigh A; Curthoys, Ian S


    The n10 component of the ocular vestibular evoked myogenic potential (oVEMP) to sound and vibration stimuli is a crossed response that has enhanced amplitude and decreased threshold in patients with CT-verified superior semicircular canal dehiscence (SSCD). However, demonstrating enhanced VEMP amplitude and reduced VEMP thresholds requires multiple trials and can be very time consuming and tiring for patients, so a specific indicator of probable SCD that is fast and not tiring would be preferred. Here we report a 1-trial indicator: that the oVEMP n10 in response to a very high frequency stimulus (4000 Hz), either air-conducted sound (ACS) or bone conducted vibration (BCV), is such a fast indicator of probable SCD. In 22 healthy subjects, oVEMP n10 at 4000 Hz was not detectable; however, in all 22 CT-verified SSCD patients tested, oVEMP n10 responses were clearly present to 4000 Hz to either ACS or BCV stimuli.

  8. Cervical and Ocular VEMP Testing in Diagnosing Superior Semicircular Canal Dehiscence.

    Hunter, Jacob B; Patel, Neil S; O'Connell, Brendan P; Carlson, Matthew L; Shepard, Neil T; McCaslin, Devin L; Wanna, George B


    Objective To determine the sensitivity and specificity of ocular and cervical vestibular evoked myogenic potentials (VEMPs) in the diagnosis of superior semicircular canal dehiscence (SCD) and to describe the VEMP response characteristics that are most sensitive to SCD and compare the findings to previous reports. Study Design Case series with chart review. Setting Two tertiary neurotologic referral centers. Subjects and Methods Cervical and ocular VEMP peak-to-peak amplitudes and thresholds from 39 adult patients older than 18 years with surgically confirmed SCD were compared with 84 age-matched controls. Results Using receiver operating characteristic (ROC) curves, cervical VEMP (cVEMP) amplitudes, cVEMP thresholds, and ocular VEMP (oVEMP) amplitudes had areas under the curve of 0.731, 0.912, and 0.856, respectively, all of which were statistically significant ( P 12.0 µV, the sensitivity and specificity were 78.6% and 81.7%, respectively. Conclusion Data from this multicenter study suggest that both cVEMP thresholds and oVEMP amplitudes remain good diagnostic tests for identifying SCD, with each test dependent on a number of factors. The sensitivity and specificity of these individual tests may vary slightly between centers depending on testing parameters used.

  9. Ocular vs. Cervical VEMPs in the Diagnosis of Superior Semicircular Canal Dehiscence Syndrome

    Zuniga, M. Geraldine; Janky, Kristen L.; Nguyen, Kimanh D.; Welgampola, Miriam S.; Carey, John P.


    Objectives To determine whether cervical vestibular evoked myogenic potential (cVEMP) thresholds or ocular VEMP amplitudes are more sensitive and specific in the diagnosis of superior semicircular canal dehiscence syndrome (SCDS). Study design Prospective case-control study Setting Tertiary referral center Subjects and Methods 29 patients with SCDS (mean age 48y; range 31–66y) and 25 age-matched controls (mean age 48y; range 30–66y). Intervention(s) cVEMP and oVEMP in response to air-conducted sound (ACS). All patients underwent surgery for repair of SCDS. Main outcome measure(s) cVEMP thresholds; oVEMP n10 and peak-to-peak amplitudes. Results cVEMP threshold results showed sensitivity and specificity ranging from 80–100% for the diagnosis of SCDS. In contrast, oVEMP amplitudes demonstrated sensitivity and specificity >90%. Conclusions oVEMP amplitudes are superior to cVEMP thresholds in the diagnosis of SCDS. PMID:23183641

  10. Temporal Bone Pneumatization and Pulsatile Tinnitus Caused by Sigmoid Sinus Diverticulum and/or Dehiscence

    Liu Wenjuan


    Full Text Available Background. Although air cells within temporal bone may play an important role in the transmission of pulsatile tinnitus (PT noise, it has not been studied systematically. Purpose. To evaluate the difference in temporal bone pneumatization between PT patients with sigmoid sinus diverticulum and/or dehiscence (SSDD and healthy people. Material and Methods. A total of 199 unilateral persistent PT patients with SSDD and 302 control subjects underwent dual-phase contrast-enhanced CT (DP-CECT, to assess the grade of temporal bone pneumatization in each ear. Results. In the bilateral temporal bone of 302 controls, 16 ears were grade I, 53 were grade II, 141 were grade III, and 394 were grade IV. Among the affected ears of 199 PT cases, 1 ear was grade I, 18 were grade II, 53 were grade III, and 127 were grade IV. There was no significant difference in the pneumatization grade between the affected PT ear and either ear in the healthy subjects (p>0.05.  Conclusion. Although air cells within the temporal bone are an important factor in the occurrence of PT, its severity does not differ significantly from the pneumatization of healthy people.

  11. Airway complications and management after lung transplantation: ischemia, dehiscence, and stenosis.

    Santacruz, Jose Fernando; Mehta, Atul C


    Overall survival rates of lung transplantation have improved since the first human lung transplantation was performed. A decline in the incidence of airway complications (AC) had been a key feature to achieve the current outcomes. Several proposed risk factors to the development of airway complications have been identified, ranging from the surgical technique to the immunosuppressive regimen. There are essentially six different airway complications post-lung transplantation. The most frequently reported complication is bronchial stenosis. Other complications include bronchial dehiscence, exophytic excessive granulation tissue formation, tracheo-bronchomalacia, bronchial fistulas, and endobronchial infections. The management of post-transplant bronchial complications needs a multispecialty team approach. Prevention of some complications may be possible by early and aggressive medical management as well as by using certain surgical techniques for transplantation. Interventional bronchoscopic procedures, including balloon bronchoplasty, cryotherapy, laser photoresection, electrocautery, high-dose endobronchial brachytherapy, and bronchial stents are among the armamentarium. Also, medical management, like antibiotic prophylaxis and therapy for endobronchial infections, or noninvasive positive-pressure ventilation in case of bronchomalacia, are used to treat an AC. In some cases, different surgical approaches are occasionally required. In this article we review the risk factors, the clinical presentation, the diagnostic methods, as well as the management options of the most common AC after lung transplantation.

  12. Autogenous bone graft combined with polylactic polyglycolic acid polymer for treatment of dehiscence around immediate dental implants.

    Hassan, Khalid S


    The use of composite bone grafts in dehiscence defects around immediate dental implants are aimed at improving the outcome of the regenerative process. The present study was designed to evaluate the efficacy of combinations of autogenous bone graft with a synthetic copolymer polylactic and polyglycolic acid (Fisiograft) on bone healing of buccal dehiscence defects around immediate dental implants. Sixteen adult male patients who each received an immediate implant for a single tooth replacement at a maxillary anterior or premolar site were included in this study. Patients were divided into 2 groups. One group received immediate dental implants augmented with autogenous bone graft combined with Fisiograft. The other group received immediate dental implants augmented with autogenous bone graft alone. The results revealed that both treatment modalities led to significant improvements for the primary outcome regarding bone fill as well as a significant reduction of probing pocket depth and gain of attachment level. Moreover, there were slightly statistically significant differences between the groups. In conclusion, the combination of autogenous bone graft and Fisiograft showed a slight superiority to autogenous bone graft alone, suggesting that it could be an optimum bone substitute for treatment of dehiscence around immediate dental implant.

    To correlate objective measures of vestibular and audiometric function as well as subjective measures of dizziness handicap with the surface area of the superior canal dehiscence (SCD). Retrospective chart review and radiological analysis. Single tertiary academic referral center. Preoperative computed tomography imaging, patient survey, audiometric thresholds, and vestibular evoked myogenic potential (VEMP) testing in patients with confirmed SCD. Image analysis techniques were developed to measure the surface area of each SCD in computed tomography imaging. Preoperative ocular and cervical VEMPs, air and bone conduction thresholds, air-bone gap, dizziness handicap inventory scores, and surface area of the SCD. Fifty-three patients (mean age 52.7 yr) with 84 SCD were analyzed. The median surface area of dehiscence was 1.44 mm (0.068-8.23 mm). Ocular VEMP amplitudes (r = 0.61, p cervical VEMP amplitudes (r = 0.62, p cervical VEMP thresholds (r = -0.56, p ocular and cervical VEMP amplitudes, cervical VEMP thresholds, and air conduction thresholds at 250 Hz are significantly correlated with the surface area of the dehiscence.

  14. [Inflammatory abdominal aortic aneurysm].

    Ziaja, K; Sedlak, L; Urbanek, T; Kostyra, J; Ludyga, T


    The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.75% cases, back pain in 31.25%, fever in 12.5% and weight loss in 6.25% of the operated patients. In all the patients ultrasound examination was performed, in 4 patients CT and in 3 cases urography. All the patients were operated on and characteristic signs of inflammatory abdominal aortic aneurysm like: thickened aortic wall, perianeurysmal infiltration or retroperitoneal fibrosis with involvement of retroperitoneal structures were found. In all cases surgery was performed using transperitoneal approach; in three cases intraoperatively contiguous abdominal organs were injured, which was connected with their involvement into periaortic inflammation. In 4 cases clamping of the aorta was done at the level of the diaphragmatic hiatus. 3 patients (9.37%) died (one patient with ruptured abdominal aortic aneurysm). Authors present diagnostic procedures and the differences in the surgical tactic, emphasizing the necessity of the surgical therapy in patients with inflammatory abdominal aortic aneurysm.

  16. Abdominal wall endometriosis.

    Upadhyaya, P; Karak, A K; Sinha, A K; Kumar, B; Karki, S; Agarwal, C S


    Endometriosis of abdominal wall scar following operation on uterus and tubes is extremely rare. The late onset of symptoms after surgery is the usual cause of misdiagnosis. Scar endometriosis is a rare disease which is difficult to diagnose and should always be considered as a differential diagnosis of painful abdominal masses in women. The diagnosis is made only after excision and histopathology of the lesion. Preoperative differentials include hernia, lipoma, suture granuloma or abscess. Hence an awareness of the entity avoids delay in diagnosis, helps clinicians to a more tailored treatment and also avoids unnecessary referrals. We report a case of abdominal endometriosis. The definitive diagnosis of which was established by histopathological studies.

  17. Wound care in horses.

    Caston, Stephanie S


    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.

  18. Current concepts in wound management and wound healing products.

    Davidson, Jacqueline R


    Current concepts in wound management are summarized. The emphasis is on selection of the contact layer of the bandage to promote a moist wound environment. Selection of an appropriate contact layer is based on the stage of wound healing and the amount of wound exudate. The contact layer can be used to promote autolytic debridement and enhance wound healing.

  19. Improving wound healing and preventing surgical site complications of closed surgical incisions: a possible role of Incisional Negative Pressure Wound Therapy. A systematic review of the literature.

    Scalise, Alessandro; Calamita, Roberto; Tartaglione, Caterina; Pierangeli, Marina; Bolletta, Elisa; Gioacchini, Matteo; Gesuita, Rosaria; Di Benedetto, Giovanni


    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

  20. Abdominal tuberculosis: Imaging features

    Pereira, Jose M. [Department of Radiology, Hospital de S. Joao, Porto (Portugal)]. E-mail:; Madureira, Antonio J. [Department of Radiology, Hospital de S. Joao, Porto (Portugal); Vieira, Alberto [Department of Radiology, Hospital de S. Joao, Porto (Portugal); Ramos, Isabel [Department of Radiology, Hospital de S. Joao, Porto (Portugal)


    Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis.

  1. [The abdominal catastrophe].

    Seiler, Christian A


    Patients with an abdominal catastrophe are in urgent need of early, interdisciplinary medical help. The treatment plan should be based on medical priorities and clear leadership. First priority should be given to achieve optimal oxygenation of blood and stabilization of circulation during all treatment-phases. The sicker the patient, the less invasive the (surgical) treatment should to be, which means "damage control only". This short article describes 7 important, pragmatic rules that will help to increase the survival of a patient with an abdominal catastrophe. Preexisting morbidity and risk factors must be included in the overall risk-evaluation for every therapeutic intervention. The challenge in patients with an abdominal catastrophe is to carefully balance the therapeutic stress and the existing resistance of the individual patient. The best way to avoid abdominal disaster, however, is its prevention.

    Three cases of blunt abdominal trauma are presented to exemplify the mechanism of trauma and the problems of diagnosis associated with any linear blow to the abdomen. The mechanisms of visceral injury are reviewed, and special attention is directed to the abdominal wall injury that can be present in these patients. This injury has special implications in directing the operative approach and repair. An unusual aortic occlusion is described which is peculiar to this type of injury.

  10. Factors Affecting Wound Healing

    Guo, S.; DiPietro, L.A.


    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

  11. Diabetes and Wound Angiogenesis

    Okonkwo, Uzoagu A.; DiPietro, Luisa A.


    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

  13. Compromised wounds in Canada.

    Denny, Keith; Lawand, Christina; Perry, Sheril D


    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.

  14. Ventral Abdominal Hernia

    Georgi Tchernev


    Full Text Available A 63-year-old Caucasian female patient presented with redness of the both foot and lower legs, as well as edema of the left lower leg, accompanied by subjective complaints of burning. Fever was not reported. Well-circumscribed oval shaped tumor formation was revealed also on the abdominal wall, with hyperpigmented and depigmented areas on its ulcerated surface, measuring approximately 10/10cm in diameter, with soft-elastic texture on palpation.  The lesion occurred in 2011, according to the patient’s history. No subjective complaints were reported in association. The performed ultrasonography revealed intestinal loops in the hernial sac, without incarceration. The diagnosis of ventral abdominal hernia without mechanical ileus was made. The patient was referred for planned surgical procedure, because of her refusal on this stage.The clinical manifestation of the tumor formation on the abdominal wall, required wide spectrum of differential diagnosis, including aneurysm of the abdominal aorta, abdominal tumor, subcutaneous tumor or metastasis or hernia. In the presented cases, the abdominal wall mass was a sporadic clinical finding in the framework of the total-body skin examination in patient with erysipelas. The lack of subjective symptoms, as well as the reported history for hysterectomy and previously abscessus were not enough indicative symptoms for the correct diagnosis. The diagnosis of non-complicated hernia was made via ultrasonography, while the clinical differentiation between hernia and other life-threatening conditions as aneurysms or tumor was not possible.

  15. Thermography Examination of Abdominal Area Skin Temperatures in Individuals With and Without Focal-Onset Epilepsy.

    King, Hollis H; Cayce, Charles Thomas; Herrin, Jeph

    Early osteopathic theory and practice, and the work of the medical intuitive Edgar Cayce suggested that the abdominal areas of individuals with epilepsy would manifest "cold spots." The etiology for this phenomenon was thought to be abdominal adhesions caused by inflammation and viscero-somatic reflexes caused by adhesions or injury to visceral or musculoskeletal system structures. Indeed, until that advent of electroencephalography in the 1930s, medical practice regarding epilepsy focused on abdominal neural and visceral structures. Following two hypotheses were formulated to evaluate any abdominal temperature phenomena: (1) an abdominal quadrant division analysis would find one or more quadrants "colder" in the focal-onset epilepsy group (ICD9-CM 345.4 and 345.5) compared to controls. (2) Total abdominal areas of individuals with focal-onset epilepsy wound be colder than a control group.

  17. Wound Assessment: Made Easy

    Ousey, Karen; Cook, Leanne


    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.




    Wound healing is a basic, highly complex, logical and well orchestrated physiologic process of interaction of various speciic molecules and cells in normal tissue function and structure restoration. In essence, genetically deined and by reined physical and chemical forces driven process, in most living beings wound healing leads to imperfect but suficient tissue repair. Some rare exceptions in wound healing, like salamander or human fetus, that can achieve complete and perfect regeneration pr...

  19. Factors Affecting Wound Healing

    Guo, S.; DiPietro, L A


    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 cutane...

  20. Diabetes and wound healing

    Svendsen, Rikke; Irakunda, Gloire; Knudsen List, Karoline Cecilie; Sønderstup-Jensen, Marie; Hölmich Rosca, Mette Maria


    Diabetes is a disease where the glucose level in the blood is high, due to either insulin resistance, impaired insulin sensitivity or no insulin production. The high glucose level causes several complications, one of them being an impaired wound healing process, which might lead to chronic wounds, ulcers. Several factors play a role in the development of ulcers, and recent research indicates that microRNA might play a significant role in skin development and wound healing. The purpose of this...

  1. Modality of wound closure after total knee replacement: are staples as safe as sutures? A retrospective study of 181 patients

    Hammerberg E Mark


    Full Text Available Abstract Background Surgical site wound closure plays a vital role in post-operative success. This effect is magnified in regard to commonly performed elective procedures such as total knee arthroplasty. The use of either sutures or staples for skin re-approximation remains a contested subject, which may have a significant impact on both patient safety and surgical outcome. The literature remains divided on this topic. Methods Two cohorts of patients at a level one trauma and regional referral center were reviewed. Cohorts consisted of consecutive total knee arthroplasties performed by two surgeons who achieved surgical wound re-approximation by either staples or absorbable subcuticular sutures. Outcome variables included time of surgery, wound dehiscence, surgical site infection per Center for Disease Control criteria and repeat procedures for debridement and re-closure. Results 181 patients qualified for study inclusion. Staples were employed in 82 cases (45.3% of total and sutures in 99 cases (54.7%. The staples group had no complications while the sutures group had 9 (9.1%. These consisted of: 4 infections (2 superficial, one deep, one organ/space; three patients required re-suturing for dehiscence; one allergic type reaction to suture material; and one gout flare resulting in dehiscence. The mean surgical time with sutures was 122.3 minutes (sd = 33.4 and with staples was 114 minutes (sd = 24.4. Conclusion This study demonstrated significantly fewer complications with staple use than with suture use. While all complications found in this study cannot be directly attributed to skin re-approximation method, the need for further prospective, randomized trials is established.

  2. Risk of progressive hearing loss in untreated superior semicircular canal dehiscence.

    Patel, Neil S; Hunter, Jacob B; O'Connell, Brendan P; Bertrand, Natalie M; Wanna, George B; Carlson, Matthew L


    Patients with incidental or minimally symptomatic superior semicircular canal dehiscence (SSCD) are usually observed, without surgical repair. However, it remains unknown whether a labyrinthine fistula of the superior semicircular canal is associated with progressive conductive or sensorineural hearing loss over time. Retrospective review at two tertiary care academic referral centers. Adults analyzed were diagnosed with SSCD by high-resolution temporal bone computed tomography and vestibular evoked myogenic potential testing and observed with a minimum of two sequential audiograms. Patients with other potential causes of hearing impairment were excluded. A total of 40 ears in 30 adult patients (median age: 59 years; 63% female) were analyzed. Median audiometric follow-up was 23 months (range 1-136 months). None experienced a sudden hearing loss over the follow-up period. In patients with audiometric follow-up of at least 20 months (median 34 months), the median change in air-conduction pure tone average and air-bone gap was 0.9 decibels (dB) per year (interquartile range [IQR] 0-2.1) and 0.7 dB per year (IQR 0-2.0), respectively. Speech discrimination scores did not differ when comparing median initial (100%) and median final (98%) scores (P = 0.77). There was no statistically significant change in bone-conduction thresholds at 0.5, 1, 2, and 4 kHz over the period of observation. The risk of progressive hearing loss with observed SSCD is low during short- and intermediate-term follow-up. Further studies are necessary to determine whether late hearing loss occurs. Such information may be critical toward patient counseling regarding the need for and timing of surgery. 4.

  3. Síndrome de Deiscência de Canal Semicircular Superior Superior Canal Dehiscence Syndrome

    Suzane da Cunha Ferreira


    Full Text Available A Síndrome de Deiscência de Canal Semicircular Superior (SDCSS, primeiramente descrita em 1998 por Minor et al., caracteriza-se por vertigem associada à presença de nistagmo, relacionados à exposição a estímulos sonoros intensos ou a modificações de pressão dentro da orelha média ou intracraniana. Disacusia, em sua maioria de padrão condutivo à audiometria tonal, também pode estar presente. Nesta revisão da literatura objetivou-se abordar a SDCSS, com seus principais sinais e sintomas, achados diagnósticos e tratamento, assim como enfatizar a importância de sua inclusão dentre as causas de vertigem, visto tratar-se de acometimento ainda pouco conhecido até mesmo entre especialistas. O diagnóstico correto, além de possibilitar seu tratamento, impede que abordagens diagnósticas e terapêuticas inapropriadas sejam realizadas.The Superior Canal Dehiscence Syndrome (SCDS was first reported by Minor at. Al. (1998, and has been characterized by vertigo and vertical-torsional eye movements related to loud sounds or stimuli that change middle ear or intracranial pressure. Hearing loss, for the most part with conductive patterns on audiometry, may be present in this syndrome. We performed a literature survey in order to to present symptoms, signs, diagnostic and therapeutic approaches to the SCDS, also aiming at stressing the great importance of including this syndrome among the tractable cause of vertigo. We should emphasize that this is a recent issue, still unknown by some specialists. The Correct SCDS diagnosis, besides enabling patient treatment, precludes misdiagnosis and inadequate therapeutic approaches.

  4. Transmastoid Approach for Resurfacing the Superior Semicircular Canal Dehiscence with a Dumpling Structure

    Xiao-Bo Ma


    Full Text Available Background: Superior semicircular canal dehiscence (SSCD is gradually recognized by otologists in recent years. The patients with SSCD have a syndrome comprising a series of vestibular symptoms and hearing function disorders which can be cured by the operation. In this study, we evaluated the characteristics of patients with SSCD and determined the effectiveness of treating this syndrome by resurfacing the canal via the transmastoid approach using a dumpling structure. Methods: Patients with SSCD, confirmed by high-resolution computed tomography and hospitalized at Beijing Tongren Hospital between November 2009 and October 2012, were included in the study. All of the patients underwent the unilateral transmastoid approach for resurfacing the canal, and received regular follow-up after surgery. Data from preoperative medical records and postoperative follow-up were comparatively analyzed to evaluate the effect of surgery. Results: In total, 10 patients and 13 ears (three left ears, four right ears, three bilateral ears were evaluated in the study, which included 7 men and 3 women. Different symptoms and distinctive manifestations of vestibular evoked myogenic potential were found in these patients. After surgery, 4 patients had complete resolution, 5 had partial resolution, and 1 patient, with bilateral SSCD, had aggravation. None of the patients suffered from serious complications such as sensorineural hearing loss, facial paralysis, cerebrospinal fluid leakage, or intracranial hypertension. Conclusions: In patients with unilateral SSCD, resurfacing the canal via the transmastoid approach using a dumpling structure is an effective and safe technique. However, more consideration is needed for patients with bilateral SSCD.

  6. Evaluation of selective treatment of penetrating abdominal trauma.

    Schmelzer, Thomas M; Mostafa, Gamal; Gunter, Oliver L; Norton, H James; Sing, Ronald F


    In penetrating abdominal trauma, diagnostic imaging and the application of selective clinical management may avoid negative celiotomy and improve outcome. We prospectively observed patients with penetrating abdominal trauma over 15 months and recorded demographics, presentation, imaging, surgical procedure, and outcome. Patients who underwent immediate laparotomy were compared with patients who were observed and/or had a computed tomography (CT) scan. Outcomes of negative versus positive and immediate versus delayed celiotomy were compared. Chi-square and Student t tests were used. A p value of less than 0.05 was considered significant. A level 1 trauma center. Adult patients who presented with penetrating abdominal injury. In all, 100 consecutive patients (mean age, 32 years) were included (male:female, 91:9; gunshot wound:stab wound, 65:35). Overall, 60 immediate and 10 delayed laparotomies were performed; 30 patients did not undergo surgery. Predictors of immediate celiotomy were hypotension (p = 0.03), anteriorly located entrance wounds (p = 0.0005), and transaxial wounds (p = 0.03). Overall morbidity and mortality was 32% and 2%, respectively. The negative celiotomy rate was 25%. Patients with a positive celiotomy had higher morbidity (p = 0.006) and longer hospital length of stay (p = 0.003) compared with negative celiotomy. A CT scan was employed in 32% of patients, with 100% sensitivity and 94% specificity. Delayed celiotomy (10%) did not adversely impact morbidity (p = 0.70) and was 100% therapeutic, with no deaths. Nonselective immediate celiotomy for penetrating abdominal trauma results in a high rate of unnecessary surgery. Hemodynamically stable patients can safely be observed and/or have contrast CT scans and undergo delayed celiotomy, if indicated. This selective treatment had no adverse effect on patient outcomes and can potentially improve overall outcome.

    A prospective trial to assess the effect of suction in an abdominal drain following cholecystectomy was carried out. Three types of closed drainage system were compared: a simple tube drain, a low negative pressure drain, and a high negative pressure drain: 120 consecutive patients undergoing cholecystectomy were randomly allocated to one of the three drainage groups. There was no significant difference in postoperative pyrexia, wound infection, chest infection, or hospital stay. This study f...

  8. Innovation and wound healing.

    Harding, Keith


    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.

  9. Wound healing in urology.

    Ninan, Neethu; Thomas, Sabu; Grohens, Yves


    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.

  10. Telemedicine for wound management

    Ravi K Chittoria


    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.

  11. Inflammation in Chronic Wounds.

    Zhao, Ruilong; Liang, Helena; Clarke, Elizabeth; Jackson, Christopher; Xue, Meilang


    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.

  12. Saliva and wound healing.

    Brand, Henk S; Ligtenberg, Antoon J M; Veerman, Enno C I


    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.

  13. Temporary abdominal closure with zipper-mesh device for management of intra-abdominal sepsis

    Edivaldo Massazo Utiyama

    Full Text Available OBJECTIVE: to present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. METHODS: we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years; 11 patients were male, and four were female. RESULTS: forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. CONCLUSION: the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.

  14. Abdominal injuries in communal crises: The Jos experience

    Emmanuel Olorundare Ojo


    Full Text Available Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7% males and 20 (18.3% females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years. The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%, colon 48 (44%, and liver 41 (37.6%. Forty-four (40.4% patients had extra-abdominal injuries involving the chest in 17 (15.6%, musculoskeletal 12 (11%, and the head in 9 (8.3%. The most prevalent weapon injuries were gunshot 76 (69.7%, explosives 12 (11%, stab injuries 11 (10.1%, and blunt abdominal trauma 10 (9.2%. The injury severity score varied from 8 to 52 (mean: 20.8 with a fatality rate of 11 (10.1% and morbidity rate of 29 (26.6%. Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems.

  15. Understanding methods of wound debridement.

    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.

  16. Abdominal emergencies in pediatrics.

    Coca Robinot, D; Liébana de Rojas, C; Aguirre Pascual, E


    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition.

  18. Microdeformation in wound healing.

    Wiegand, Cornelia; White, Richard


    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.

  20. [The role of laparoscopy in emergency abdominal surgery].

    Balén, E; Herrera, J; Miranda, C; Tarifa, A; Zazpe, C; Lera, J M


    Abdominal emergencies can also be operated on through the laparoscopic approach: the approach can be diagnostic laparoscopy, surgery assisted by laparoscopy or laparotomy directed according to the findings of the laparoscopy. The general contraindications refer above all to the state of haemodynamic instability of the patient and to seriously ill patients (ASA IV). In the absence of any specific counter-indications for the specific laparoscopic procedure to be carried out, many abdominal diseases requiring emergency surgery can be performed with the laparoscopic approach. The most frequent indications are appendicitis, acute colecistitis, gastroduodenal perforation, occlusion of the small intestine, and some abdominal traumas. With a correct selection of patients and the appropriate experience of the surgeon, the results are excellent and better than open surgery (less infection of the wound, complications, hospital stay and postoperative pain). A detailed explanation is given of the basic aspects of the surgical technique in the most frequent procedures of emergency laparoscopy.

  1. Acquired Abdominal Intercostal Hernia: A Case Report and Literature Review

    Tripodi, Giuseppe


    Acquired abdominal intercostal hernia (AAIH) is a rare disease phenomenon where intra-abdominal contents reach the intercostal space directly from the peritoneal cavity through an acquired defect in the abdominal wall musculature and fascia. We discuss a case of a 51-year-old obese female who arrived to the emergency room with a painful swelling between her left 10th rib and 11th rib. She gave a history of a stab wound to the area 15 years earlier. A CT scan revealed a fat containing intercostal hernia with no diaphragmatic defect. An open operative approach with a hernia patch was used to repair this hernia. These hernias are difficult to diagnose, so a high clinical suspicion and thorough history and physical exam are important. This review discusses pathogenesis, clinical presentation, complications, and appropriate treatment strategies of AAIH. PMID:25197605

  3. Evidence that an evolutionary transition from dehiscent to indehiscent fruits in Lepidium (Brassicaceae) was caused by a change in the control of valve margin identity genes.

    Mühlhausen, Andreas; Lenser, Teresa; Mummenhoff, Klaus; Theißen, Günter


    In the Brassicaceae, indehiscent fruits evolved from dehiscent fruits several times independently. Here we use closely related wild species of the genus Lepidium as a model system to analyse the underlying developmental genetic mechanisms in a candidate gene approach. ALCATRAZ (ALC), INDEHISCENT (IND), SHATTERPROOF1 (SHP1) and SHATTERPROOF2 (SHP2) are known fruit developmental genes of Arabidopsis thaliana that are expressed in the fruit valve margin governing dehiscence zone formation. Comparative expression analysis by quantitative RT-PCR, Northern blot and in situ hybridization show that their orthologues from Lepidium campestre (dehiscent fruits) are similarly expressed at valve margins. In sharp contrast, expression of the respective orthologues is abolished in the corresponding tissue of indehiscent Lepidium appelianum fruits, indicating that changes in the genetic pathway identified in A. thaliana caused the transition from dehiscent to indehiscent fruits in the investigated species. As parallel mutations in different genes are quite unlikely, we conclude that the changes in gene expression patterns are probably caused by changes in upstream regulators of ALC, IND and SHP1/2, possible candidates from A. thaliana being FRUITFULL (FUL), REPLUMLESS (RPL) and APETALA2 (AP2). However, neither expression analyses nor functional tests in transgenic plants provided any evidence that the FUL or RPL orthologues of Lepidium were involved in evolution of fruit indehiscence in Lepidium. In contrast, stronger expression of AP2 in indehiscent compared to dehiscent fruits identifies AP2 as a candidate gene that deserves further investigation.

  4. Does Laparoscopic Hysterectomy Increase the Risk of Vaginal Cuff Dehiscence? An Analysis of Outcomes from Multiple Academic Centers and a Review of the Literature.

    Mikhail, Emad; Cain, Mary Ashley; Shah, Madhvi; Solnik, M Jonathon; Sobolewski, Craig J; Hart, Stuart


    Vaginal cuff dehiscence represents a serious, but infrequent complication after hysterectomy, with a reported increased incidence following a laparoscopic approach. Various risk factors have been proposed including laparoscopically placed suture, surgical experience, use of electrosurgery, surgical indication, and obesity. Technical aspects of the procedure itself have also been questioned such as the variable use of monopolar electrosurgery during colpotomy and the suture type or number of layers chosen to reapproximate the vaginal cuff. Nothwithstanding the tendency for cuff dehiscence to occur following laparoscopic approach, there remains a paucity of high-quality data that supports or refutes this finding or clearly defines the mechanism(s) by which this event occurs allowing for the proposal of objective guidelines for reducing risk. Various techniques have been proposed to decrease the risk of vaginal cuff dehiscence during endoscopic hysterectomy, including use of monopolar current on cutting mode, achievement of cuff hemostasis with sutures rather than electrocoagulation, use of a two-layer cuff closure with polydioxanone suture, and use of bidirectional barbed suture for cuff closure. The authors experience at three university-based minimally invasive gynecologic surgery programs showed a low rate of vaginal cuff dehiscence in their own practices. Large randomized controlled trials are needed to truly determine whether there is a difference in vaginal cuff dehiscence between surgical modalities for hysterectomy as well as to determine the true risk factors.

  5. Greater omentum in reconstruction of refractory wounds

    沈余明; 沈祖尧


    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.

  6. Abdominal paracentesis and thoracocentesis.

    Lee, Ser Yee; Pormento, James G; Koong, Heng Nung


    Abdominal paracentesis and thoracocentesis are common bedside procedures with diagnostic, therapeutic and palliative roles. We describe a useful and familiar a useful and familiar technique with the use of a multiple lumen catheter commonly used for central venous line insertion for drainage of ascites or moderate to large pleural effusions. The use of a multiple lumen catheter allows easier and more rapid aspiration of fluid with a smaller probability of the side holes being blocked as compared to the standard needle or single catheter methods. This is particularly useful in situations where the dedicated commercial kits for thoracocentesis and abdominal paracentesis are not readily available.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

  8. [Abdominal actinomycosis with IUD].

    Kamprath, S; Merker, A; Kühne-Heid, R; Schneider, A


    We report a case of abdominal actinomycosis in a 54 year old woman using an intrauterine device for a period of 8 years. The most important finding was a tuboovarialabscess at the left pelvic side with involvement of the serosa of the jejunum, ileum, sigma, and omentum majus. Intraoperative exploration showed a solid retroperitoneal infiltration between the pelvic side wall and sigma. Another infiltration was found on the left side of the abdominal wall. The diagnosis was confirmed by histopathological examination and the patient was treated by a combination of Aminopenicillin and Metronidazol. After a period of three months we observed a complete regression of the clinical and the MRI findings.

  9. Early Healing Events after Periodontal Surgery: Observations on Soft Tissue Healing, Microcirculation, and Wound Fluid Cytokine Levels

    Kaner, Doğan; Soudan, Mouaz; Zhao, Han; Gaßmann, Georg; Schönhauser, Anna; Friedmann, Anton


    Early wound healing after periodontal surgery with or without enamel matrix derivative/biphasic calcium phosphate (EMD/BCP) was characterized in terms of soft tissue closure, changes of microcirculation, and expression of pro- and anti-inflammatory cytokines in gingival crevicular fluid/wound fluid (GCF/WF). Periodontal surgery was carried out in 30 patients (18 patients: application of EMD/BCP for regeneration of bony defects; 12 patients: surgical crown lengthening (SCL)). Healthy sites were observed as untreated controls. GCF/WF samples were collected during two post-surgical weeks. Flap microcirculation was measured using laser Doppler flowmetry (LDF). Soft tissue healing was evaluated after two weeks. GCF/WF levels of interleukin 1β (IL-1β), tumour necrosis factor (TNF-α), IL-6, and IL-10 were determined using a multiplex immunoassay. Surgery caused similar reductions of flap microcirculation followed by recovery within two weeks in both EMD/BCP and SCL groups. GCF/WF and pro-inflammatory cytokine levels were immediately increased after surgery, and returned only partially to baseline levels within the two-week observation period. Levels of IL-10 were temporarily reduced in all surgical sites. Flap dehiscence caused prolonged elevated levels of GCF/WF, IL-1β, and TNF-α. These findings show that periodontal surgery triggers an immediate inflammatory reaction corresponding to the early inflammatory phase of wound healing, and these inflammation measures are temporary in case of maintained closure of the flap. However, flap dehiscence causes prolonged inflammatory exudation from the periodontal wound. If the biological pre-conditions for periodontal wound healing are considered important for the clinical outcome, care should be taken to maintain primary closure of the flap. PMID:28134829

  11. Adult abdominal hernias.

    Murphy, Kevin P


    Educational Objectives and Key Points. 1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both elective and acute circumstances because of rapid acquisition, capability of multiplanar reconstruction, good spatial resolution, and anatomic depiction with excellent sensitivity for most complications. 3. Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment, whereas MRI is beneficial when there is reasonable concern that a patient\\'s symptoms could be attributable to a hernia or a musculoskeletal source. 4. Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination. 5. The diagnosis of an internal hernia not only is a challenging clinical diagnosis but also can be difficult to diagnose with imaging: Closed-loop small-bowel obstruction and abnormally located bowel loops relative to normally located small bowel or colon should prompt assessment for an internal hernia.

  15. The Potential of Honey to Promote Wound Healing in Periodontology: a Pilot Randomized Clinical Trial

    Seyed-Mohammad Fereshtehnejad


    Full Text Available Background & Objectives: Honey has been used as a nutraceutical in many traditional and ancient remedies. Considering well documented benefits of honey to accelerate wound healing, for the first time we aimed to assess intra oral surgical wound healing process with honey. Methods: We designed a pilot randomized placebo controlled cross-over clinical trial. Patients who required bilateral Modified Widman Flap (MWF surgery randomly assigned to receive either 15 cc topical Persian Thymus Vulgaris concentrated honey three times a day or normal saline as placebo with the same amount at the site of the surgery for seven consecutive days. After a 35-day wash-out period the study groups were crossed. The primary efficacy outcome was changes in healing index (Landry index and the secondary efficacy outcome were changes in gingival and plaque indices (Loe & Sillness, Sillness & Loe indices. It also includes safety issues consisting of any allergic reaction, delayed healing or wound dehiscence. Results: Ten patients enrolled with the mean age of 36 (±1.5 ranged between 35-40 yrs. There was a significant improvement in wound healing considering time and treatment effects in both groups, although faster wound healing observed in honey treated patients (P<0.001. In both groups gingival indices were noticed to be improved by the time during the first phase of the study. Both groups displayed aggravated Plaque formation; nevertheless it was merely statistically significant in the control group [F (3, 27 =12.88, P value < 0.001]. All wounds healed normally and no adverse events recorded. Conclusion: Our study established the safety, efficacy and feasibility of topical honey to promote periodontal surgical wound healing.

  1. bHLH142 regulates various metabolic pathway-related genes to affect pollen development and anther dehiscence in rice

    Ranjan, Rajeev; Khurana, Reema; Malik, Naveen; Badoni, Saurabh; Parida, Swarup K.; Kapoor, Sanjay; Tyagi, Akhilesh K.


    Apposite development of anther and its dehiscence are important for the reproductive success of the flowering plants. Recently, bHLH142, a bHLH transcription factor encoding gene of rice has been found to show anther-specific expression and mutant analyses suggest its functions in regulating tapetum differentiation and degeneration during anther development. However, our study on protein level expression and gain-of-function phenotype revealed novel aspects of its regulation and function during anther development. Temporally dissimilar pattern of bHLH142 transcript and polypeptide accumulation suggested regulation of its expression beyond transcriptional level. Overexpression of bHLH142 in transgenic rice resulted in indehiscent anthers and aborted pollen grains. Defects in septum and stomium rupture caused anther indehiscence while pollen abortion phenotype attributed to abnormal degeneration of the tapetum. Furthermore, RNA-Seq-based transcriptome analysis of tetrad and mature pollen stage anthers of wild type and bHLH142OEplants suggested that it might regulate carbohydrate and lipid metabolism, cell wall modification, reactive oxygen species (ROS) homeostasis and cell death-related genes during rice anther development. Thus, bHLH142 is an anther-specific gene whose expression is regulated at transcriptional and post-transcriptional/translational levels. It plays a role in pollen maturation and anther dehiscence by regulating expression of various metabolic pathways-related genes. PMID:28262713

  2. Cuspal dehiscence at a post and along the stent cloth in a bovine pericardium heart valve implanted for seven years.

    Guidoin, Robert; Bes, Taniela Marli; Cianciulli, Tomas Francisco; Klein, Julianne; Li, Bin; Gauvin, Robert; Guzman, Randolph; Rochette-Drouin, Olivier; Germain, Lucie; Zhang, Ze


    A failing mitral valve prosthesis made from bovine pericardium was explanted from a 50-year-old patient. Preoperative transthoracic-echocardiography had confirmed severe mitral regurgitation due to structural failure of this HP Bio bovine pericardium heart valve prosthesis. The explanted device was examined macroscopically, by scanning electron microscopy (SEM), by light microscopy, and by transmission electron microscopy (TEM). Samples of unassembled patches of bovine pericardium were used as a pre-implantation control to better understand the changes that occurred in the structure of the pericardium following the 7 years of implantation. Examination confirmed complete dehiscence of a cusp along a valve post and the stent: This detached cusp was observed floating in the bloodstream at echocardiography. The fibrous pannus overgrowth was well developed along the stent and extended to the bottom of the cusps both on the inflow and the outflow sides. The fibrous panni were found to be poorly adhesive to the pericardium cusps and had become stiff, thus impairing the opening and closure of the valve. The structure of the pericardium cusps was severely deteriorated compared to the control bovine pericardium tissue samples. The collagen bundles were frequently broken and more stretched in the explanted device, lacking the wavy histological pattern of normal collagen fibers. However, the tissues were devoid of any calcification. In conclusion, the failure mode of this valve was the dehiscence of a cusp from a valve post and along the stent cloth in the absence calcification.

  5. Surface enhanced Raman spectroscopy as a point-of-care diagnostic for infection in wound effluent

    Ghebremedhin, Meron; Yesupriya, Shubha; Crane, Nicole J.


    In military medicine, one of the challenges in dealing with large combat-related injuries is the prevalence of bacterial infection, including multidrug resistant organisms. This can prolong the wound healing process and lead to wound dehiscence. Current methods of identifying bacterial infection rely on culturing microbes from patient material and performing biochemical tests, which together can take 2-3 days to complete. Surface Enhanced Raman Spectroscopy (SERS) is a powerful vibrational spectroscopy technique that allows for highly sensitive structural detection of analytes adsorbed onto specially prepared metal surfaces. In the past, we have been able to discriminate between bacterial isolates grown on solid culture media using standard Raman spectroscopic methods. Here, SERS is utilized to assess the presence of bacteria in wound effluent samples taken directly from patients. To our knowledge, this is the first attempt for the application of SERS directly to wound effluent. The utilization of SERS as a point-of-care diagnostic tool would enable physicians to determine course of treatment and drug administration in a matter of hours.

  6. A clinical study on the influence of suturing material on oral wound healing

    Gazivoda Dragan


    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.

  13. Debridement for surgical wounds.

    Dryburgh, Nancy; Smith, Fiona; Donaldson, Jayne; Mitchell, Melloney


    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

  14. Fibronectin and wound healing.

    Grinnell, F


    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.

  15. Arginine metabolism in wounds

    Albina, J.E.; Mills, C.D.; Barbul, A.; Thirkill, C.E.; Henry, W.L. Jr.; Mastrofrancesco, B.; Caldwell, M.D.


    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.

  16. 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.

  17. Vacuum-assisted wound closure in vascular surgery - clinical and cost benefits in a developing country

    Končar Igor


    Full Text Available Background/Aim. Surgical and chronic wounds in vascular patients might contribute to limb loss and death. Vacuum-assisted closure (VAC - Kinetic Concepts, Inc. (KCI, has been increasingly used in Western Europe and the USA clinical practice for 15 years. Advantages of this method are faster wound healing, wound approximation, lower wound related treatment costs and improved quality of life during treatment. Evidence related to the usage of VAC therapy in vascular patients and cost effectiveness of VAC therapy in a developing country are lacking. The aim of this study was to explore results of VAC therapy in vascular surgery comparing to conventional methods and to test cost effects in a developing country like Serbia. Methods. All patients with wound infection or dehiscence operated at the tertiary vascular university clinic in the period from January 2011 - January 2012, were treated with VAC therapy. The primary endpoint was wound closure, while secondary endpoints were hospital stay, the number of weekly dressings, costs of wound care, working time of medical personnel. The patients were divided into groups according to the wound type and location: wound with exposed synthetic vascular implant (25%, laparotomy (13%, foot amputation (29%, major limb amputation (21%, fasciotomy (13%. The results of primary and secondary endpoint were compared with the results of conventional treatment during the previous year. Results. There was one death (1/42, 2.38% and one limb loss (1/12, 2.38% in the VAC group, and 8 deaths (8/38, 21.05% and 5 (5/38, 13.15% limb losses in the patients treated with conventional therapy. In the VAC group there was one groin bleeding (1/12, 2.38%, one groin reinfection (1/12, 2.38% and one resistance to therapy with a consequent limb loss. Costs of hospital stay (p < 0.001 and nursing time (p < 0.001 were reduced with VAC therapy in the group with exposed graft. Conclusion. VAC therapy is the effective method for care of

  19. Experience with irrigation analgesia after abdominal hysterectomy

    R. V. Garyaev


    Full Text Available A prospective randomized clinical trial was performed in 100 patients who underwent abdominal hysterectomy under endotracheal anesthesia based on sevoflurane and fentanyl. Intraoperatively, ketorolac 30 mg was administered intramuscularly after induction of anesthesia and paracetamol 1 g was injected intravenously 30–40 minutes prior to surgical termination in a control group (n = 25. For postoperative anal- gesia, promedol, tramadol, and ketorolac were used intramuscularly and paracetamol was given intravenously. Three study groups (n = 2 in each differed from the control group in that during wound suturing a multiperforated catheter was placed above the peritoneum over a length of 15 cm, through which a 10-ml bolus of 0.75 % ropivacaine was first administered, followed by continuous infusion of 0.2 % ropivacaine at a rate of 8 ml/hour for 36 hours. In one irrigation group, ketorolac 30 mg was injected intramuscularly t.i.d. for 2 days; in another group, the agent was added to a ropivacaine solution calculated with reference to 180 mg for 2 days; in the third group, ketoprofen 100 mg instead of ketorolac was used b.i.d. for 2 days. Pain level (by digital rating scale, 0–10 and the need for analgesics were measured. There was no sta- tistical significant difference in the level of pain and the need for analgesics between the wound irrigation and control groups.

  20. Unexpected multiple intra-abdominal injuries after projectile fragmentation: report of three cases.

    Unlü, Aytekin; Petrone, Patrizio; Karşıdağ, Tamer; Asensio, Juan A


    Explosives create and energize particles that act as projectiles prone to further fragmentation or create other secondary missiles in the body. These fragments may result in secondary injuries. This has been repeatedly described in the orthopedic and neurosurgical literature. We report the same process for abdominal injuries after fascial penetration in the military setting. This is an observational case series study. Local wound exploration as a standard approach was performed in conscious patients who sustained abdominal wall injuries. Patients with negative physical examination were excluded from the study. An intraperitoneal injury was assumed in those with a full-thickness fascial defect, and laparotomy was performed. Twenty patients met the study eligibility criteria. Of those 20 patients, 12 had negative wound exploration and were excluded from the study, while abdominal organ injuries were found in eight (40%) patients. During laparotomy, projectile-induced injuries in a sprayed distribution were found in three (38%) of these patients. These injuries were far from the predictable trajectory and in the absence of bone fragmentation. The overall mean number of peritoneal defects was 1.7, and a mean 6.8 intra-abdominal injuries for each peritoneal defect were found when through-and-through injuries were excluded.Despite a single peritoneal defect, there may be multiple intraperitoneal injuries due to further fragmentation of the projectile. Under mass casualties, wound exploration with a full-thickness fascial defect could serve as an indicator of possible intra-abdominal injuries, and consequently indicate exploratory laparotomy.

  1. Physicians' Abdominal Auscultation

    John, Gade; Peter, Kruse; Andersen, Ole Trier


    Background: Abdominal auscultation has an important position in the physical examination of the abdomen. Little is known about rater agreement. The aim of this study was to describe rater agreement and thus, indirectly, the value of the examination. Methods: In a semi-virtual setup 12 recordings...... of the intestinal sounds from 8 patients with acute abdominal pain and 4 healthy volunteers were presented to 100 physicians. The physicians were asked to characterize the intestinal sounds as normal or pathologic. Fisher's exact test was used for comparison between groups of physicians. Results: Overall, 72......% of the answers with regard to healthy volunteers concluded that the sounds were normal (equalling agreement), whereas 64% of answers with regard to intestinal obstruction concluded that the sounds were pathologic (but agreement was higher due to agreement on wrong diagnosis in one case). Bowel sounds from...

  3. Ruptured abdominal aortic aneurysm.

    Sachs, T; Schermerhorn, M


    Ruptured abdominal aortic aneurysm (AAA) continues to be one of the most lethal vascular pathologies we encounter. Its management demands prompt and efficient evaluation and repair. Open repair has traditionally been the mainstay of treatment. However, the introduction of endovascular techniques has altered the treatment algorithm for ruptured AAA in most major medical centers. We present recent literature and techniques for ruptured AAA and its surgical management.

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

  5. Wound pH depends on actual wound size

    Sirkka, T; Apell, S P


    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.

  6. Principles of Wound Management and Wound Healing in Exotic Pets.

    Mickelson, Megan A; Mans, Christoph; Colopy, Sara A


    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. Emphasis is placed on novel methods of treating wounds and species differences in wound management and healing. Copyright © 2016 Elsevier Inc. All rights reserved.




    Full Text Available Purpose: A prospective study of incisional surgical site infection in abdominal surgeries was conducted to find out incidence, common predisposing factors and microbiological profile. METHODS: 375 patients who underwent abdominal surgeries were studied in a span of 1 year. They were divided into two groups – group 1 – 316 cases who did not develop Surgical Site Infection (SSI, the 2nd group – 59 cases that developed SSI. These patients were studied by interviewing and examination according to a set proforma. The results were statistically analyzed by comparing averages using Chi square chart for finding significance of difference where applicable. RESULT: The overall SSI incidence was 15.7 % (59/375. In elective surgeries, the SSI rate was 5.7% and in emergency surgeries, it was 28.6%. It was found that SSI increased with increasing age linearly. Other significant factors involved were increasing class of wound (dirty > clean wound class, increased preoperative stay, presence of remote site infection, increased duration of surgery and use of drains. E. coli was found to be the most common organism causing SSI in abdominal operations. CONCLUSION: SSI can be reduced by decreasing the preoperative hospital stay, appropriate antibiotic administration policies, preoperative control of remote site infections, adequate preoperative patient preparation, reducing the duration of surgery to minimum, judicious use of drains and intraoperative maintenance of asepsis and following operation theatre discipline properly.

  8. Reduced dermis thickness and AGE accumulation in diabetic abdominal skin.

    Niu, Yiwen; Cao, Xiaozan; Song, Fei; Xie, Ting; Ji, Xiaoyun; Miao, Mingyuan; Dong, Jiaoyun; Tian, Ming; Lin, Yuan; Lu, Shuliang


    Dermatological problems in diabetes might play an important role in the spontaneous ulcers and impaired wound healing that are seen in diabetic patients. Investigation of the cause of diabetic skin disorders is critical for identifying effective treatment. The abdominal full-thickness skin tissues of 33 patients (14 nondiabetic and 19 diabetic) were analyzed. The cell viability and malondialdehyde (MDA) production of fibroblasts were measured after advanced glycosylation end product (AGE)-bovine serum albumin (BSA) exposure. Cutaneous histological observation showed reduced thickness of the diabetic abdominal dermis with morphological characteristics of obscured multilayer epithelium and shortened, thinned, and disorganized collagen fibrils with focal chronic inflammatory cell infiltration when compared with controls of the same age. Accumulation of AGEs in diabetic skin was prominent. Less hydroxyproline, higher myeloperoxidase activity, and increased MDA content were detected in diabetic skin. In vitro, the time- and dose-dependent inhibitory effects of AGE-BSA on fibroblast viability as well as the fact that AGE-BSA could promote MDA production of fibroblasts were shown. It is shown that the accumulation of AGEs in diabetic skin tissue induces an oxidative damage of fibroblasts and acts as an important contributor to the thinner diabetic abdominal dermis. The authors believe that diabetic cutaneous properties at baseline may increase the susceptibility to injury, and diabetic wounds possess atypical origin in the repair process.

  9. Evaluating clinical abdominal scoring system in predict- ing the necessity of laparotomy in blunt abdominal trauma

    Erfantalab-Avini Peyman


    Full Text Available 【Abstract】 Objectives: Trauma is among the lead- ing causes of death. Medical management of blunt abdomi- nal trauma (BAT relies on judging patients for whom lap- arotomy is mandatory. This study aimed to determine BAT patients’ signs, as well as paraclinical data, and to clarify the accuracy, sensitivity, specificity, positive and negative predictive value of clinical abdominal scoring system (CASS, a new scoring system based on clinical signs, in predicting whether a BAT patient needs laparotomy or not. Methods: Totally 400 patients suspected of BAT that arrived at the emergency department of two university hos- pitals in Tehran from March 20, 2007 to March 19, 2009 were included in this study. They were evaluated for age, sex, type of trauma, systolic blood pressure, Glasgow coma scale (GCS, pulse rate, time of presentation after trauma, abdomi- nal clinical findings, respiratory rate, temperature, hemoglo- bin (Hb concentration, focused abdominal sonography in trauma (FAST and CASS. Results: Our measurements showed that CASS had an accuracy of 94%, sensitivity of 100%, specificity of 88%, positive predictive value of 90% and negative predictive value of 100% in determining the necessity of laparotomy in BAT patients. Moreover, in our analysis, systolic blood pressure, GCS, pulse rate, Hb concentration, time of presen- tation after trauma, abdominal clinical findings and FAST were also shown to be helpful in confirming the need for laparotomy (P<0.05. Conclusion: CASS is a promising scoring system in rapid detection of the need for laparotomy as well as in minimizing auxiliary expense for further evaluation in BAT patients, thus to promote the cost-benefit ratio and accu- racy of diagnosis.

  10. Vacuum-assisted closure for complex cranial wounds involving the loss of dura mater.

    Powers, Alexander K; Neal, Matthew T; Argenta, Louis C; Wilson, John A; DeFranzo, Anthony J; Tatter, Stephen B


    The aim in this study was to describe the safety and efficacy of vacuum-assisted closure (VAC) in patients with complex cranial wounds with extensive scalp, bone, and dural defects who were not candidates for immediate free tissue transfer. Five patients (4 men and 1 woman) ages 24-73 years with complex cranial wounds were treated with VAC at Wake Forest Baptist Medical Center. Etiologies included trauma, squamous cell carcinoma, and malignant meningioma. Cutaneous wound defects measured as large as 15 cm in diameter. Four of the 5 patients had open skull defects with concomitant dural defects, and 1 patient had dural dehiscence. After surgical debridement, all 5 patients were treated with the direct application of a VAC device to a reapproximated dura mater (1 patient), to a pericranial flap (1 patient), or to a regenerative tissue matrix overlying CNS tissue (3 patients). In all cases involving open cranial wounds, the VAC device promoted granulation tissue formation over the dural substitute, prevented CSF leakage, and kept the wounds free from local infection. The duration of VAC therapy ranged from 16 to 91 days. Although VAC therapy was intended as a temporary measure until these patients could be stabilized for larger tissue transfer procedures or they succumbed to their primary pathology, 1 patient had a successful skin graft following VAC therapy. Hydrocephalus requiring shunt placement developed in 2 patients during VAC therapy. The VAC dressings applied to a tissue matrix or other barrier over brain tissue in extensive cranial wounds are safe and well tolerated, providing a functional barrier and preventing infection.

  14. [Stab wounds in emergency department].

    Bège, T; Berdah, S V; Brunet, C


    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.

  15. Sagging Eye Syndrome or Nemaline Rod Myopathy? Divergence Insufficiency with Levator Dehiscence as an Overlapping Symptom between Two Diagnoses

    Ghadiali, Larissa K.; Brannagan III, Thomas H.; Moonis, Gul; Faust, Phyllis L.; Odel, Jeffrey G.


    A 78-year-old woman complained of gradual, painless onset of horizontal binocular diplopia associated with progressive axial weakness. Physical examination revealed esotropia that was greater at distance than at near vision, bilateral levator dehiscence, and normal abducting saccadic speeds. Given the age of the patient and compatible clinical findings, the diagnosis of Sagging Eye Syndrome (SES) was made. However, further work-up with a muscle biopsy suggested Sporadic Late-Onset Nemaline Myopathy (SLONM) as the cause of her progressive muscle weakness. Although rare, external ophthalmoplegia has been described in the literature as a presenting symptom in SLONM. To elucidate the pathological mechanism for the patient's diplopia, an MRI of the orbits was performed, which revealed findings consistent with SES. This case aims to highlight the importance of integrating clinical findings during the diagnostic process and serves as a reminder that diplopia can be a common symptom for an uncommon diagnosis.

    Purpose: In this study, we aimed to investigate the frequency of SCD and its distribution and relationship with clinical outcomes on thin-section CT of the temporal bone. Materials and methods: Digital temporal bone CT images of 850 consecutive patients (1700 temporal bone CTs, 5100 SCs) who presented with a range of complaints such as vertigo, deafness, ear pain, fullness, and discharge between January 2008 and December 2011 were re-evaluated. Axial and oblique coronal reconstruction images of the temporal bone were made with a reconstruction thickness of 0.5 mm. Additionally, superior SC was evaluated in two perpendicular planes. Results: Out of 850 patients, 70 had completely normal temporal bone CT. Ninety-three patients had at least one SCD. In the temporal bone-based evaluation, 119 (26 bilateral, 67 unilateral) of 1700 temporal bones (7%) showed dehiscence. The SC-based evaluation revealed 125 SCD (2.5%) in 5100 SCs. The total number and rates of SCD were as follows: superior 103 (82.4%), posterior 13 (10.4%), and lateral nine (7.2%). Twenty of the 93 patients with SCD (21.5%) revealed no other findings on their temporal bone CTs. We determined a significant correlation between vestibular complaints, conductive hearing loss and SCD but there was no correlation between mixed, sensorineural hearing loss and SCD. Conclusion: We determined the frequency of SCD in 11% of patients and 7% of temporal bones. With regards to the distribution, the superior SC showed the highest dehiscence rate (82.4%). We found a significant correlation between vestibular symptoms, conductive hearing loss and SCD.

  19. Association between idiopathic intracranial hypertension and sigmoid sinus dehiscence/diverticulum with pulsatile tinnitus: a retrospective imaging study

    Zhaohui, Liu; Qing, Li [Capital Medical University, Beijing Tongren Hospital, Department of Radiology, Beijing (China); Cheng, Dong; Xiao, Wang; Xiaoyi, Han; Pengfei, Zhao; Han, Lv; Zhenchang, Wang [Capital Medical University, Beijing Friendship Hospital, Department of Radiology, Beijing (China)


    The mechanism of occurrence of sigmoid sinus dehiscence/diverticulum (SSDD) in pulsatile tinnitus (PT) patients remains under debate. Its association with idiopathic intracranial hypertension (IIH) lacks evidence, which is important for therapeutic planning and improving the clinical outcome. This study aimed to evaluate the association between SSDD and IIH by comparing the prevalence of several established imaging features of IIH between PT patients with SSDD and healthy volunteers. Thirty-three unilateral PT patients with SSDD identified on CT images and 33 age- and sex-matched healthy volunteers underwent T1-weighted volumetric magnetic resonance imaging (MRI). The optic nerve, pituitary gland, transverse sinus, and ventricles were assessed. The prevalence of established IIH imaging features was compared between the two groups. Furthermore, the PT patients were divided into two subgroups: PT patients with dehiscence only and PT patients with diverticulum. The same statistical analysis was performed on each pathophysiologic entity respectively. The PT patients with SSDD showed a significantly higher prevalence of empty sella (P < 0.001), flattened posterior sclera (P = 0.001), vertical tortuosity of the optic nerve (P = 0.001), protrusion of the optic nerve (P = 0.006), transverse sinus stenosis (P = 0.011), and distension of the optic nerve sheath (P = 0.000). There were no significant differences between the PT and control groups in the maximum widths of the third and fourth ventricles and the lateral ventricle size. In contrast to controls, the imaging findings persisted in both of pathophysiologic entities, except for transverse sinus stenosis. Several IIH imaging features occur more frequently in PT patients with SSDD than in healthy individuals, which suggests a potential correlation between SSDD with PT and IIH. (orig.)

  20. Sutures versus staples for wound closure in orthopaedic surgery: a randomized controlled trial

    Shantz Jesse A


    Full Text Available Abstract Background A recently published meta-analysis comparing metallic staples to sutures in orthopaedic procedures revealed three fold increase in risk for infection in stapled wounds. The studies included in the meta-analysis are at risk of bias due to experimental design limitations. A large randomized controlled trial is proposed to direct orthopaedic surgeons in their choice of wound closure material. Methods/Design A parallel group randomized controlled trial with institutional review board approval will be conducted. Patients will be randomized intraoperatively to have skin wounds closed with sutures or staples. Dressings will be used to maintain blinding outcome assessors. The primary outcome measure will be a composite all-cause wound complication outcome measure composed of: infection, wound drainage, wound necrosis, blistering, dehiscence, suture abscess and material sensitivity reaction. An independent review board blinded to treatment assignment will adjudicate suspected complications based on clinical data. All deceased patients will also be reviewed. An interim analysis of complications will take place after half of the patients have been recruited. All data will be analyzed by a blinded statistician. Dichotomous primary and secondary outcome measures will be analyzed using the Chi-squared statistic. Continuous outcome measures will be analyzed using Student's t-test. Subgroup analysis will compare infection rates using sutures versus staples in each anatomic area (upper extremity, pelvis/acetabulum, hip/femur, knee, ankle. A further subgroup analysis will be conducted comparing trauma patients to elective surgery patients. Non-infected revision surgery will also be compared to primary surgery. Discussion Wound closure material is an afterthought for many orthopaedic surgeons. The combined results of several comparative trials suggests that the choice of wound closure materials may have an impact on the rate of surgical site

  2. Effects of aging on abdominal wall healing in rats

    Biondo-Simões Maria de Lourdes Pessole


    Full Text Available PURPOSE: The aim of this study was to assess abdominal wall healing in old and young adult rats. METHODS: On average, young animals were 110 days old and old animals were 762 days old. A 4.0 cm median laparotomy was performed under anesthesia, followed by laparorrhaphy on two synthesis planes, i.e. peritoneum-muscle-aponeurosis and skin, using continuous 5.0 nylon sutures. The animals were evaluated on the 3rd, 7th, 14th and 21st postoperative days. The resistance of the two planes was studied separately and a histopathologic analysis was performed on sections stained with hematoxylin-eosin and Sirius Red. Immunohistochemical analysis was also carried out using PCNA, LCA and CD34. RESULTS: The skin scars gained resistance in a similar manner at the initial time points, but those of young rats were more resistant on the 21st day (p=0.0029. Total and type III collagen content was similar in the two groups and type I collagen content was higher in young animals on the 14th day. Inflammatory cell infiltration was more marked in the skin wounds of young animals on the 3rd day (p=0.0190. Reepithelialization was similar and angiogenesis was more intense in the skin wounds of young animals on the 14th day (p=0.0062. The peritoneum-muscle-aponeurosis wounds gained similar resistance during the early phases, but were more resistant on the 14th day (p=0.0005 and on the 21st day (p=0.0023 in old rats Collagen concentration was higher in the wounds of old animals on the 3rd day (p=0.0112 and in the wounds of young animals on the 21st day (p=0.0348. The inflammatory reaction was more intense in the wounds of old animals on the 3rd day (p=0.0060 and angiogenesis was more intense on the 14th day (0.0432. CONCLUSION: Although there are some differences in the healing course between young and old animals, age, of itself, does not impair the healing of abdominal wall wounds in rats.

    The purpose of this article is to provide an up to date review on the spectrum of applications of perfusion computed tomography (CT) in the abdomen. New imaging techniques have been developed with the objective of obtaining a structural and functional analysis of different organs. Recently, perfusion CT has aroused the interest of many researchers who are studying the applicability of imaging modalities in the evaluation of abdominal organs and diseases. Per-fusion CT enables fast, non-invasive imaging of the tumor vascular physiology. Moreover, it can act as an in vivo biomarker of tumor-related angiogenesis.

    Although most frequently presenting with lower abdominal pain, appendicitis, colitis, and diverticulitis can cause pain throughout the abdomen and can cause peritoneal and retroperitoneal symptoms. Evaluation and management of lower intestinal disease requires a nuanced approach by the emergency physician, sometimes requiring computed tomography, ultrasonography, MRI, layered imaging, shared decision making, serial examination, and/or close follow-up. Once a presumed or confirmed diagnosis is made, appropriate treatment is initiated, and may include surgery, antibiotics, and/or steroids. Appendicitis patients should be admitted. Diverticulitis and inflammatory bowel disease can frequently be managed on an outpatient basis, but may require admission and surgical consultation.

  7. [Differential diagnosis of abdominal pain].

    Frei, Pascal


    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain.

  9. Wound healing and treating wounds: Differential diagnosis and evaluation of chronic wounds.

    Morton, Laurel M; Phillips, Tania J


    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.

  10. Burn wound: How it differs from other wounds?

    V K Tiwari


    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.

    Wake, Sarah; Abhyankar, Aruna; Hutton, Kim


    A cystic lymphangioma arising within the abdomen is a rare entity in children. It may present with an abdominal mass and symptoms of abdominal pain, vomiting, and anorexia. These nonspecific clinical symptoms are often attributed to more common acute pediatric conditions. In this report, we describe two pediatric cases of intra-abdominal cystic lymphangioma that were initially diagnosed and treated as appendicitis. True diagnosis was only achieved on surgical excision and pathological investigation of cystic material.

  15. Molecular pathology of wound healing.

    Kondo, Toshikazu; Ishida, Yuko


    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.

  19. Superficial fascial system repair: an abdominoplasty technique to reduce local complications after caesarean delivery.

    Al-Benna, Sammy; Al-Ajam, Yazan; Tzakas, Elias


    Abdominal incision complications are a major source of morbidity after caesarean delivery. Repair of the superficial fascial system may avert local complications after caesarean delivery by minimising tension to the skin and increasing the initial biomechanical strength of wound which has the potential to decrease early wound dehiscence and as a by-product correct suprapubic bulging.

  20. Post-operative Abdominal Wall Mucormycosis-a Case Series.

    Nain, Prabhdeep Singh; Matta, Harish; Singh, Kuldip; Chhina, Deepinder; Trehan, Munish; Batta, Nishant


    Mucormycosis is caused by saprophtytic fungi which cause acute invasive zygomycosis. It clinically presents with necrosis, and on histopathology, acute and chronic infiltrates are seen. It rarely infects a healthy host, but is devastating in an immunocompromised host. We studied five cases with post-operative abdominal wall mucormycosis, three females and two males. Three patients were post-operative while the other two had mucormycosis following trauma and infection was found in sutured wound. All were initially diagnosed as cases of necrotizing fasciitis. Two patients eventually survived after intensive medical therapy and extensive debridements.

  4. Cell therapy for wound healing.

    You, Hi-Jin; Han, Seung-Kyu


    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.

  5. Nontraumatic abdominal emergencies: acute abdominal pain: diagnostic strategies

    Marincek, B. [Institute of Diagnostic Radiology, University Hospital Zurich, Raemistrasse 100, 8091 Zurich (Switzerland)


    Common causes of acute abdominal pain include appendicitis, cholecystitis, bowel obstruction, urinary colic, perforated peptic ulcer, pancreatitis, diverticulitis, and nonspecific, nonsurgical abdominal pain. The topographic classification of acute abdominal pain (pain in one of the four abdominal quadrants, diffuse abdominal pain, flank or epigastric pain) facilitates the choice of the imaging technique. The initial radiological evaluation often consists of plain abdominal radiography, despite significant diagnostic limitations. The traditional indications for plain films - bowel obstruction, pneumoperitoneum, and the search of ureteral calculi - are questioned by helical computed tomography (CT). Although ultrasonography (US) is in many centers the modality of choice for imaging the gallbladder and the pelvis in children and women of reproductive age, CT is considered to be one of the most valued tools for triaging patients with acute abdominal pain. CT is particularly beneficial in patients with marked obesity, unclear US findings, bowel obstruction, and multiple lesions. The introduction of multidetector row CT (MDCT) has further enhanced the utility of CT in imaging patients with acute abdominal pain. (orig.)

    Burke A. Cunha


    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.

    OBJECTIVES: Healing is an event that is fundamental to the success of total knee arthroplasty. The aims of the present study were to compare the rates of complications related to wound healing between two groups of volunteers submitted to total knee arthroplasty and to evaluate the effects of postoperative oxygen supplementation by means of a nasal catheter. METHOD: A total of 109 patients who underwent total knee arthroplasty were randomized into two groups, namely, groups that did and did not receive postoperative oxygen supplementation via a nasal catheter. The surgical wound was monitored every day during the hospital stay and on the 7th, 14th, 21st, 30th and 42nd postoperative days. Characteristics related to healing were observed, including hyperemia, dehiscence, necrosis, phlyctenules and deep and superficial infection. RESULTS: There were no cases of deep infection. Hyperemia was statistically correlated with the total number of complications in the groups, with oxygen demonstrated to be a protective factor against hyperemia. Approximately 30% of the patients who exhibited hyperemia had other complications, independent of oxygen supplementation. CONCLUSION: Oxygen supplementation following total knee arthroplasty was shown to be effective in diminishing hyperemia around the operative wound. The development of hyperemia was a precursor to other complications, irrespective of whether oxygen supplementation was used. PMID:25518030

  14. [Physiology and pathophysiology of wound healing of wound defects].

    Mutschler, W


    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.

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.

  16. Complex wounds Feridas complexas

    Marcus Castro Ferreira


    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.

  17. Mechanics of cutaneous wound rupture.

    Swain, Digendranath; Gupta, Anurag


    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.

    Although the number of elective operations for abdominal aortic aneurysms (AAA) is increasing, the sex- and age-standardised mortality rate of AAAs continues to rise, especially among men aged 65 years or more. The lethality of ruptured AAA continues to be 80-95%, compared with 5-7% by elective...... inhibit further AAA progression. All 4 existing RCTs point in the same direction, viz. in favour of screening of men aged 65 and above. We found that screening significantly reduced AAA-related mortality by 67% within the first five years (NNT = 352). Restriction of screening to men with previous...... year gained was 157 euro [1,170 DKK] and the cost per QALY at 178 euro [1,326 DKK]. In all, the ethical dilemma of the prophylactic operation, and the limited psychological side effects seem not to outweigh the benefits of screening. Conclusively, we found that offering men aged 65-73 years screening...

  1. Common questions about wound care.

    Worster, Brooke; Zawora, Michelle Q; Hsieh, Christine


    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.

  2. Abdominal migraine in the differential diagnosis of acute abdominal pain.

    Cervellin, Gianfranco; Lippi, Giuseppe


    Although traditionally regarded as a specific pediatric disease, abdominal migraine may also be observed in adults. Unfortunately, however, this condition is frequently overlooked in the differential diagnosis of abdominal pain in the emergency department (ED). A 30-year-old woman presented to our ED complaining of abdominal pain and vomiting, lasting for 12 hours. The pain was periumbilical, continuous, and not associated with fever or diarrhea. The physical examination and the results of conventional blood tests were normal. The patient was treated with intravenous ketoprofen, metoclopramide, and ranitidine, obtaining a prompt relief of symptoms. She had a history of similar episodes in the last 15 years, with several ED visits, blood test examinations, ultrasonography of the abdomen, and upper gastrointestinal endoscopies. Celiac disease, porphyry, sickle cell disease, and inflammatory bowel disease were all excluded. In July 2012, she became pregnant, and she delivered a healthy baby on April 2013. Until November 2014, she has remained asymptomatic. Based on the clinical characteristics of the abdominal pain episodes, the exclusion of any alternative diagnosis, and the relief of symptoms during and after pregnancy, a final diagnosis of abdominal migraine could be established. A skilled emergency physician should always consider abdominal migraine in the differential diagnosis of patients admitted to the ED with abdominal pain, especially when the attacks are recurrent and no alternative diagnosis can be clearly established.

  3. Stone formation in peach fruit exhibits spatial coordination of the lignin and flavonoid pathways and similarity to Arabidopsis dehiscence

    Piagnani M Claudia


    Full Text Available Abstract Background Lignification of the fruit endocarp layer occurs in many angiosperms and plays a critical role in seed protection and dispersal. This process has been extensively studied with relationship to pod shatter or dehiscence in Arabidopsis. Dehiscence is controlled by a set of transcription factors that define the fruit tissue layers and whether or not they lignify. In contrast, relatively little is known about similar processes in other plants such as stone fruits which contain an extremely hard lignified endocarp or stone surrounding a single seed. Results Here we show that lignin deposition in peach initiates near the blossom end within the endocarp layer and proceeds in a distinct spatial-temporal pattern. Microarray studies using a developmental series from young fruits identified a sharp and transient induction of phenylpropanoid, lignin and flavonoid pathway genes concurrent with lignification and subsequent stone hardening. Quantitative polymerase chain reaction studies revealed that specific phenylpropanoid (phenylalanine ammonia-lyase and cinnamate 4-hydroxylase and lignin (caffeoyl-CoA O-methyltransferase, peroxidase and laccase pathway genes were induced in the endocarp layer over a 10 day time period, while two lignin genes (p-coumarate 3-hydroxylase and cinnamoyl CoA reductase were co-regulated with flavonoid pathway genes (chalcone synthase, dihydroflavanol 4-reductase, leucoanthocyanidin dioxygen-ase and flavanone-3-hydrosylase which were mesocarp and exocarp specific. Analysis of other fruit development expression studies revealed that flavonoid pathway induction is conserved in the related Rosaceae species apple while lignin pathway induction is not. The transcription factor expression of peach genes homologous to known endocarp determinant genes in Arabidopsis including SHATTERPROOF, SEEDSTCK and NAC SECONDARY WALL THICENING PROMOTING FACTOR 1 were found to be specifically expressed in the endocarp while the

  4. Identifying wound prevalence using the Mobile Wound Care program.

    Walker, Judi; Cullen, Marianne; Chambers, Helen; Mitchell, Eleanor; Steers, Nicole; Khalil, Hanan


    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.

    Full Text Available Background: Obesity is a medical condition that may adversely affect wellbeing and leading to increased incidence of many health problems. Abdominal obesity tends to be associated with weight gain and obesity and it is significantly connected with different disorders like coronary heart disease and type II diabetes mellitus.This study was conducted to investigate the efficacy of vacuum therapy as compared to abdominal exercises on abdominal obesity in overweight and obese women. Methods: Thirtyoverweight and obese women participated in this study with body mass index > 25 kg/m2andwaist circumference ≥ 85 cm. Their ages ranged from 28 - 40 years old.The subjects were excluded if they have diabetes, abdominal infection diseases or any physical limitation restricting exercise ability. They were randomly allocated into two equal groups; group I and group II. Group I received vacuum therapy sessions (by the use of LPG device in addition to aerobic exercise training. Group II received abdominal exercises in addition to the same aerobic exercisesgiven to group I. This study was extended for successive 8 weeks (3 sessions/ week. All subjects were assessed for thickness ofnthe abdominal skin fold, waist circumference and body mass index. Results: The results of this study showeda significant difference between group I and group II post-interventionas regarding to the mean values of waist circumference and abdominal skin fold thickness (p<0.05. Conclusion: It can be concluded that aerobic exercises combined with vacuum therapy (for three sessions/week for successive 8 weeks have a positive effect on women with abdominal obesity in terms of reducing waist circumference and abdominal skin fold thickness.

    Systematic review. To identify risk factors and preventive methods for wound complications and instrumentation failure after metastatic spine surgery. We focused on two postoperative complications of metastatic spine tumor surgery: wound complications and instrumentation failure and preventive measures. We performed a systematic review of the literature from 1980 to 2015. The articles were analyzed for the presence of documented infection and/or wound complications and instrumentation failure. Forty articles met our inclusion criteria for wound complications and prevention. There is very low level of evidence that preoperative radiation, preoperative neurological deficit, revision procedures, and posterior approaches can contribute to wound complications (infections, wound dehiscence). There is very low level of evidence that plastic surgery soft tissue reconstruction, intrawound vancomycin powder, and percutaneous pedicle screws may prevent postoperative wound complications. Fourteen articles met our inclusion criteria for instrumentation failure. There is very low level of evidence that constructs greater than six levels, positive sagittal balance, preoperative radiation, and history of chest wall resection can contribute to implant failures. • For patients undergoing revision metastatic spine tumor surgery, plastic surgery should perform the soft tissue reconstruction (strong recommendation/very low quality of evidence).• For patients undergoing metastatic spine tumor surgery, plastic surgery may perform immediate soft tissue reconstruction (weak recommendation/very low quality of evidence).• For patients undergoing metastatic spine tumor surgery, intrawound vancomycin can be applied to decrease the risk of postoperative wound infections (weak recommendation/very low quality of evidence).• For patients undergoing metastatic spine tumor surgery, percutaneous pedicle screws can be placed to decrease the risk of postoperative wound complications (weak

  8. [Using Acupressure to Improve Abdominal Bloating in a Hemicolectomy Patient: A Nursing Experience].

    Tseng, Yi-Ling; Hsu, Chun-Hung; Tseng, Hui-Chen


    This article describes a nursing experience applying the protocol of bilateral Zusanli (ST-36) acupressure to reduce abdominal bloating in a colon cancer patient who had undergone a right hemicolectomy. The period of care was between November 13 and November 23, 2014. Data were collected through direct care, interviews, observation, and physical assessment. The main health problems of the patient included anxiety, surgical wound pain, and abdominal bloating. We provided pre- and postoperative routine nursing care, wound pain management, and the protocol of Zusanli (ST-36) acupressure for reducing abdominal bloating. Results of care recorded the first passage of flatus and intestinal motility during the second postoperative day, with no complaints of bloating from the fourth postoperative day. The subject exhibited a relaxed mood and slept soundly following each acupressure session. Furthermore, the subject reported experiencing no abdominal bloating during the week following discharge, during which he continued to follow the acupressure protocol. This article provides support via an instance of nursing care for the effectiveness of the Zusanli (ST-36) acupressure in improving abdominal bloating and thus reducing the complications of hemicolectomy surgery.

  9. Transarterial coil embolization in treatment of gross hematuria following self-inflicted stab wound in a horse-shoe kidney

    Pezeshki Rad Masoud


    Full Text Available 【Abstract】Horseshoe kidney is an uncommon anomaly of the urinary system with an increased risk of injury during penetrating and blunt abdominal traumas. Self-inflicted abdominal stab wound, a rare type of abdominal injury, accounts for only a small percentage of suicidal at-tempts and may be infrequently encountered by physicians in trauma centers. Psychiatric disorders and alcohol or drug abuse are common risk factors in cases of self-stabbing. Here we report a rare case of self-stabbing of a horseshoe kidney. The case was a 19-year-old man with self-inflicted abdominal stab wound who was referred to our department of radiology due to re-occurred gross hematuria three days after exploratory laparotomy and surgical repair of injured abdominal organs. A horseshoe kidney was incidentally found in the patient’s abdominal computed tomography. Renal angiography revealed active contrast extravasation from one of the segmental arteries. Selective transarterial embolization with a coil was successfully performed to con-trol the hematuria. Key words: Embolization, therapeutic; Kidney; Wounds, stab

    A 50-year-old man was admitted with fever and chill sensation 6 months ago. Transthoracic echocardiography (TTE) showed left and right coronary cusp prolapses and a thickened tissue of the aortic curtain. Congestive heart failure due to active infective aortic valve endocarditis was diagnosed, and he underwent aortic valve replacement. The aortic annulus was reconstructed using a glutaraldehydetreated autologous pericardium. Six months after surgery, TTE showed severe aortic regurgitation and saccular change in the aortic annulus. Transesophageal echocargiography showed some echo free space from left to noncoronary cusp and abnormal movement of the prosthetic valve annulus. Intraoperative examination showed dehiscence of the pericardial patch from the aortic wall, but no finding of infection. Aortic valve rereplacement was performed with reconstruction of the aortic annulus using a bovine pericardium. To prevent the dehiscence of the pericardial patch from the aortic wall, sutures fixing the prosthetic valve were passed from outside of the aortic wall.

  11. Recent advances in topical wound care

    Sarabahi, Sujata


    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,...

  12. Wound healing: part II. Clinical applications.

    Janis, Jeffrey; Harrison, Bridget


    Treatment of all wounds requires adequate wound bed preparation, beginning with irrigation and débridement. Complicated or chronic wounds may also require treatment adjuncts or specialized wound healing products. An extensive body of research and development has introduced novel wound healing therapies and scar management options. In this second of a two-part continuing medical education series on wound healing, the reader is offered an update on current wound healing technologies and recommendations for obtaining optimal outcomes.

    Wound biology is complex. Wounds which were until recently seen only as defects in tissues are now increasingly interpreted in cellular and molecular terms. Growth factors, cytokines, proteases and adhesion molecules which participate in wound healing are discussed in this article. From a clinical perspective, conceptual shifts of importance, including moist wound healing, wound bed preparation and wound assessment, are presented. The frontiers of therapeutics employed in wound healing contin...

  14. The wound hormone jasmonate

    Koo, Abraham J. K.; Howe, Gregg A.


    Plant tissues are highly vulnerable to injury by herbivores, pathogens, mechanical stress, and other environmental insults. Optimal plant fitness in the face of these threats relies on complex signal transduction networks that link damage-associated signals to appropriate changes in metabolism, growth, and development. Many of these wound-induced adaptive responses are triggered by de novo synthesis of the plant hormone jasmonate (JA). Recent studies provide evidence that JA mediates systemic...

  15. Telemedicine in wound care.

    Chanussot-Deprez, Caroline; Contreras-Ruiz, José


    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.

  16. Social facilitation of wound healing.

    Detillion, Courtney E; Craft, Tara K S; Glasper, Erica R; Prendergast, Brian J; DeVries, A Courtney


    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.

  17. Use of biological meshes for abdominal wall reconstruction in highly contaminated fields

    Andrea; Cavallaro; Emanuele; Lo; Menzo; Maria; Di; Vita; Antonio; Zanghì; Vincenzo; Cavallaro; Pier; Francesco; Veroux; Alessandro; Cappellani


    Abdominal wall defects and incisional hernias represent a challenging problem. In particular, when a synthetic mesh is applied to contaminated wounds, its removal is required in 50%-90% of cases. Biosynthetic meshes are the newest tool available to surgeons and they could have a role in ventral hernia repair in a potential-ly contaminated field. We describe the use of a sheet of bovine pericardium graft in the reconstruction of abdominal wall defect in two patients. Bovine pericardium graft was placed in th...

  18. Síndrome compartimental abdominal

    Misael Guzmán Nápoles

    Full Text Available Desde el siglo XIX se conocen los efectos negativos del aumento de la presión intraabdominal, pero no se le prestó la debida atención a este trastorno hasta la última década del pasado siglo y la primera del actual. En este artículo exponemos las definiciones de los términos presión intrabdominal, hipertensión intrabdominal y síndrome compartimental abdominal, que fueron tomadas por consenso y aprobadas por la World Society of the Abdominal Compartment Syndrome. En nuestro medio, para el diagnóstico de la hipertensión intrabdominal y del síndrome compartimental abdominal se requiere medir la presión intrabdominal, secundariamente la presión de perfusión abdominal y se deben correlacionar estos datos con signos de deterioro clínico en el paciente. Las medidas terapéuticas médicas en relación con el síndrome compartimental abdominal son limitadas; cuando este es sintomático la descompresión abdominal es el tratamiento ya establecido. Enfatizamos en que el diagnóstico temprano de la hipertensión intrabdominal y del síndrome compartimental abdominal contribuyen a disminuir el desarrollo de un síndrome de disfunción múltiple de órganos y por tanto a reducir la mortalidad en estos pacientes. Con el objetivo de actualizar los conocimientos sobre hipertensión intrabdominal y síndrome compartimental abdominal, su diagnóstico y tratamiento, realizamos una minuciosa revisión actualizada de diversos artículos referentes al síndrome compartimental abdominal, tanto en el ámbito nacional como internacional.

  19. Skull vibration-induced nystagmus test in unilateral superior canal dehiscence and otosclerosis: a vestibular Weber test.

    Dumas, Georges; Lion, Alexis; Karkas, Alexandre; Perrin, Philippe; Perottino, Flavio; Schmerber, Sébastien


    The skull vibration-induced nystagmus test (SVINT) acts as a vestibular Weber test and reveals a vibration-induced nystagmus (VIN), elicited mainly on the vertex location, with a horizontal or torsional component beating more often toward the side of the lesion in superior canal dehiscence (SCD) than in otosclerosis (OS). In SCD, the VIN vertical component is most often up-beating. These results suggest more a global vestibular contribution than the sole stimulation of the superior semicircular canal. This study aimed to evaluate the possible occurrence of nystagmus during SVINT in unilateral conductive hearing loss related to SCD or OS. The slow-phase velocities (SPVs) of the VIN horizontal, torsional, and vertical components were recorded in patients with a unilateral otologic lesion (17 SCD, 38 OS) and 12 control subjects. Vibratory stimulations (60 Hz, 100 Hz) were applied on the vertex and on each mastoid. In SCD, VIN was observed in 82% of patients with a primarily torsional, horizontal, and vertical (up-beating) component in 40%, 30%, and 30%, respectively. Horizontal and torsional components beat toward the side of the lesion more often than in OS. Higher SPVs were observed after vertex stimulation. In OS, VIN was sparse with low amplitude and was not systematically lateralized to a specific side.

  1. Economics of abdominal wall reconstruction.

    Bower, Curtis; Roth, J Scott


    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

  2. 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.

  3. The arterial supply of the cervical and thoracic spinal muscles and overlying skin: Anatomical study with implications for surgical wound complications.

    Yue, Brian Yin Ting; le Roux, Cara Michelle; Corlett, Russell; De La Harpe, David; Richardson, Martin; Ashton, Mark


    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.

  4. Abdominal aortic feminism.

    Mortimer, Alice Emily


    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer. 2014 BMJ Publishing Group Ltd.

  5. Micromanaging Abdominal Aortic Aneurysms

    Lars Maegdefessel


    Full Text Available The contribution of abdominal aortic aneurysm (AAA disease to human morbidity and mortality has increased in the aging, industrialized world. In response, extraordinary efforts have been launched to determine the molecular and pathophysiological characteristics of the diseased aorta. This work aims to develop novel diagnostic and therapeutic strategies to limit AAA expansion and, ultimately, rupture. Contributions from multiple research groups have uncovered a complex transcriptional and post-transcriptional regulatory milieu, which is believed to be essential for maintaining aortic vascular homeostasis. Recently, novel small noncoding RNAs, called microRNAs, have been identified as important transcriptional and post-transcriptional inhibitors of gene expression. MicroRNAs are thought to “fine tune” the translational output of their target messenger RNAs (mRNAs by promoting mRNA degradation or inhibiting translation. With the discovery that microRNAs act as powerful regulators in the context of a wide variety of diseases, it is only logical that microRNAs be thoroughly explored as potential therapeutic entities. This current review summarizes interesting findings regarding the intriguing roles and benefits of microRNA expression modulation during AAA initiation and propagation. These studies utilize disease-relevant murine models, as well as human tissue from patients undergoing surgical aortic aneurysm repair. Furthermore, we critically examine future therapeutic strategies with regard to their clinical and translational feasibility.

  6. [Gunshot wound to the kidney: case report and therapeutic management].

    Maruschke, M; Hakenberg, O W


    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.

  7. The management of perineal wounds

    Ramesh k Sharma


    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.

  8. [Monitoring of intra-abdominal pressure and abdominal perfusion pressure in urgent abdominal surgery].

    Raĭbuzhis, E N; Fot, E V; Gaĭdukov, K M; Kirov, M Iu


    To evaluate the changes in intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) during perioperative period in urgent abdominal surgery and to assess the relationship of these parameters with gas exchange and tissue perfusion. Twenty-four patients undergoing emergency abdominal surgery were enrolled into a prospective observational study. We recorded IAP APP, mean arterial pressure, arterial and venous blood gases after induction of anesthesia, at the end of surgery, and 6, 12, 48 and 72 h postoperatively. LAP was measured by nasogastric tube using CiMON monitor (Pulsion Medical Systems, Germany). In addition, we studied the relationship of IAP and APP with blood gases parameters. We observed perioperative increase of IAP (> 12 mm Hg) in 75% of enrolled patients, tendency to postoperative rise of IAP and transient increase of arterial lactate at 6 h after surgery. APP remained within normal values. We found positive correlation of APP with PaO2/FiO2 and ScvO2 at 72 hours after surgery. Transient perioperative increase of IAP was observed in 75% patients undergoing urgent abdominal surgery; however in parallel with intensive care the abdominal perfusion pressure remained within normal values. Abdominal perfusion is related with arterial oxygenation and central venous saturation.

    We report the case of a 15-year-old boy suffering from progressive dyspnea on exertion and painful abdominal protrusion. Final diagnosis of intra-abdominal tuberculosis (TB), including lymphadenopathy and abdominal abscess formation, was made following elective laparotomy. This type of disease is a rare manifestation of extrapulmonary tuberculosis. The imaging findings in unenhanced and contrast-enhanced MRI and laparoscopic images are presented. Differential diagnosis of abdominal abscess formation and other fungal or bacteriological infections, as well as the imaging findings of this type of lesion, are discussed. This case demonstrates that atypical manifestation of TB may remain unrecognized; thus, awareness of this kind of manifestation of tuberculosis may prevent patients from being subjected to inappropriate therapies.

  3. A Combined Comparative Transcriptomic, Metabolomic, and Anatomical Analyses of Two Key Domestication Traits: Pod Dehiscence and Seed Dormancy in Pea (Pisum sp.

    Petr Smýkal


    Full Text Available The origin of the agriculture was one of the turning points in human history, and a central part of this was the evolution of new plant forms, domesticated crops. Seed dispersal and germination are two key traits which have been selected to facilitate cultivation and harvesting of crops. The objective of this study was to analyze anatomical structure of seed coat and pod, identify metabolic compounds associated with water-impermeable seed coat and differentially expressed genes involved in pea seed dormancy and pod dehiscence. Comparative anatomical, metabolomics, and transcriptomic analyses were carried out on wild dormant, dehiscent Pisum elatius (JI64, VIR320 and cultivated, indehiscent Pisum sativum non-dormant (JI92, Cameor and recombinant inbred lines (RILs. Considerable differences were found in texture of testa surface, length of macrosclereids, and seed coat thickness. Histochemical and biochemical analyses indicated genotype related variation in composition and heterogeneity of seed coat cell walls within macrosclereids. Liquid chromatography–electrospray ionization/mass spectrometry and Laser desorption/ionization–mass spectrometry of separated seed coats revealed significantly higher contents of proanthocyanidins (dimer and trimer of gallocatechin, quercetin, and myricetin rhamnosides and hydroxylated fatty acids in dormant compared to non-dormant genotypes. Bulk Segregant Analysis coupled to high throughput RNA sequencing resulted in identification of 770 and 148 differentially expressed genes between dormant and non-dormant seeds or dehiscent and indehiscent pods, respectively. The expression of 14 selected dormancy-related genes was studied by qRT-PCR. Of these, expression pattern of four genes: porin (MACE-S082, peroxisomal membrane PEX14-like protein (MACE-S108, 4-coumarate CoA ligase (MACE-S131, and UDP-glucosyl transferase (MACE-S139 was in agreement in all four genotypes with Massive analysis of cDNA Ends (MACE data.

    Téot, Luc


    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.

    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.

    Tapish, Sahu; Taha, Mustafa; Naresh, Garg; Neeraj, Dhamija; Malik Vinod, K


    Mucormycosis of the anterior abdominal wall is an uncommon disease and it is very rare to find this disease in immunocompetent, non-diabetic patients which usually affects patients with trauma, with contaminated wounds, patients with underlying malignancies or patients with immunocompromised state, e.g., diabetics. We herein report a case of primary cutaneous mucormycosis in an immunocompetent and non-diabetic patient. Our patient was a 48-year-old female, executive by profession. She was diagnosed to have cutaneous mucormycosis of the anterior abdominal wall, and was managed with multiple debridements of the wound and intravenous amphotericin B therapy. She was administered a total of 1500 mg of liposomal amphotericin B and when fully healed, split skin grafting was done. We would like to emphasize the importance of high index of suspicion and early start of therapy in a condition with high rate of mortality.

  7. Updates on abdominal desmoid tumors


    Desmoid tumor is a monoclonal, fibroblastic proliferation arising in musculoaponeurotic structures. This connective tissue hyperplasia infiltrates locally, recurs frequentiy after resection but does not metastasize. Abdominal desmoid occurs sporadically, in association with some familial syndromes and often represents a clinical dilemma for surgeons. The enigmatic biology and anatomical location of abdominal desmoids make treatment recommendations difficult. This distinct pathological entity is reviewed with a specific focus on aetiology and management.

  8. Development of a wound dressing composed of hyaluronic acid sponge containing arginine and epidermal growth factor.

    Matsumoto, Yasuhiro; Kuroyanagi, Yoshimitsu


    Hyaluronic acid (HA) has the ability to promote wound healing. Epidermal growth factor (EGF) is able to promote the proliferation of various cell types, in addition to epidermal cells. A novel wound dressing was designed using high-molecular-weight hyaluronic acid (HMW-HA) and low-molecular-weight hyaluronic acid (LMW-HA). Spongy sheets composed of cross-linked high-molecular-weight hyaluronic acid (c-HMW-HA) were prepared by freeze-drying an aqueous solution of HMW-HA containing a crosslinking agent. Each spongy sheet was immersed into an aqueous solution of LMW-HA containing arginine (Arg) alone or both Arg and epidermal growth factor (EGF), and were then freeze-dried to prepare two types of product. One was a wound dressing composed of c-HMW-HA sponge containing LMW-HA and Arg (c-HMW-HA/LMW-HA + Arg; Group I). The other was a wound dressing composed of c-HMW-HA sponge containing LMW-HA, Arg and EGF (c-HMW-HA/LMW-HA + Arg + EGF; Group II). The efficacy of these products was evaluated in animal tests using rats. In the first experiment, each wound dressing was applied to a full-thickness skin defect with a diameter of 35 mm in the abdominal region of Sprague-Dawley (SD) rats, leaving an intact skin island measuring 15 mm in diameter in the central area of this skin defect. Commercially available polyurethane film dressing was then applied to each wound dressing as a covering material. In the control group, the wound surface was covered with polyurethane film dressing alone. Both wound dressings (Group I and Group II) potently decreased the size of the full-thickness skin defect and increased the size of the intact skin island, when compared with the control group. The wound dressing in Group II showed particularly potent activity in increasing the distance of epithelization from the intact skin island. This suggests that EGF release from the spongy sheet serves to promote epithelization. The wound dressing in Group II enhanced early-stage inflammation after 1 week

    Karaca, Mehmet Ali; Kartal, Nil Deniz; Erbil, Bülent; Öztürk, Elif; Kunt, Mehmet Mahir; Şahin, Tevfik Tolga; Özmen, Mehmet Mahir


    This study aimed to evaluate injury patterns of patients admitted to the emergency department with gunshot wounds, results of imaging studies, treatment modalities, outcomes, mortality ratios, and complications. A retrospective descriptive study was carried out including a total number of one hundred and forty-two patients admitted to Hacettepe University Emergency Department with gunshot injuries between January 1, 1999 and December 31, 2013. The Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), Injury Severity Score (ISS), and the Trauma and Injury Severity Score (TRISS) probability of survival for penetrating trauma were calculated for all patients. Among the one hundred and forty-two patients in the study, one hundred and twenty-eight (90.1%) were male. Mean age was 36 years. On admission, the average GCS score was 13, mean RTS was 6.64, median ISS was 5 and median TRISS probability for survival was 99.4% for penetrating trauma. Fluid was detected in three (13%) patients in FAST, whereas intra-abdominal solid organ injury and bowel injury were detected in 11 (58%) patients in abdominal CT. The pneumothorax, hemothorax and lung injuries were detected in 10 (40%) patients, whereas hemothorax was detected only in one patient with thoracic injury by chest X-ray. Twenty four (16.9%) patients died; eighteen patients (75%) had isolated severe intracranial injuries, two (8.3%) had thoracic injuries with head and neck injuries, and four (16.7%) patients had intra-abdominal organ injuries (one with concomitant head injury). Ten patients were brought to the ED in cardiopulmonary arrest. In dead patients, GCS, RTS and TRISS were significantly lower, and ISS were significantly higher than in surviving patients. Twenty three (95.8%) patients were in critical injury level (ISS 25-75, actually ISS >50) in the exitus group. Mortality rates in gunshot wound patients with cranial injuries are very high. Spontaneous return is not seen in patients brought to the ED in arrest

  10. Wound healing complications and the use of mammalian target of rapamycin inhibitors in kidney transplantation: a critical review of the literature.

    Nashan, Björn; Citterio, Franco


    Surgical complications, including events such as lymphocele and urological complications that affect wound healing, are reported with an incidence of 15% to 32% after kidney transplantation. The experience of the surgeon and comorbidities play an important role in determining the risk of such complications occurring. Since the introduction of the inosine 5'-monophosphate dehydrogenase inhibitors (mycophenolate mofetil) to the immunosuppressive armamentarium, replacing the antimetabolite prodrug azathioprine, reports have associated certain forms of wound healing complications (wound dehiscence, impaired healing, lymphocele, and incisional hernia) with the use of these agents. When mammalian target of rapamycin (mTOR) inhibitors (sirolimus, everolimus) became available, these findings were observed increasingly, particularly in direct comparisons with inosine 5'-monophosphate dehydrogenase inhibitors. The purpose of this article was to review the reported incidence of wound healing complications from randomized clinical trials that investigated the use of sirolimus- and everolimus-based treatment regimens in de novo kidney transplantation and the information available from the U.S. Food and Drug Administration database. The clinical trials included were primarily identified using biomedical literature database searches, with additional studies added at the authors' discretion. This review summarizes these studies to consider whether modern mTOR inhibitor-based immunosuppressive regimens exert and affect wound healing after kidney transplantation.

  11. Preliminary results from 28 cases of pilonidal cyst treated by excision and primary closure of the wound, reinforced with support suturing

    Nelson de Souza Liboni


    Full Text Available Objectives: To describe the results of the surgical technique of pilonidalcyst excision with margins and primary closure of the operative woundwith support suturing. Methods: Twenty-eight patients with pilonidaldisease admitted to a private clinic between 1999 and 2006 underwentsurgical treatment by means of an elliptical longitudinal medial incisionproportional to the palpable tumor size and excision of cyst with 2-cmmargins above, below and laterally, and primary closure of the wound.To reduce the tension in the operative wound, suturing was performed,with a single support stitch of horizontal U-shape. The patients werefollowed up for periods ranging from 6 months to 3 years. Results:Two patients developed abscesses at the surgical site (7.1%, andone required complete opening of the operative wound for drainage.Both underwent excision and primary closure again. The pathologicalexamination demonstrated that these were not cases of relapse, butof recurrent abscess. No cases of non-infected collection (seroma andhematoma, spontaneous dehiscence of the operative wound or diseaserecurrence were recorded. Conclusions: The technique of pilonidal cystexcision with margins and primary closure of the wound reinforcedwith support suturing seems to be attractive, since it is characterizedby low complexity and low infection rate. Studies with larger samplesare needed to validate this surgical technique.

  12. Common abdominal emergencies in children.

    D'Agostino, James


    Because young children often present to EDs with abdominal complaints, emergency physicians must have a high index of suspicion for the common abdominal emergencies that have serious sequelae. At the same time, they must realize that less serious causes of abdominal symptoms (e.g., constipation or gastroenteritis) are also seen. A gentle yet thorough and complete history and physical examination are the most important diagnostic tools for the emergency physician. Repeated examinations and observation are useful tools. Physicians should listen carefully to parents and their children, respect their concerns, and honor their complaints. Ancillary tests are inconsistent in their value in assessing these complaints. Abdominal radiographs can be normal in children with intussusception and even malrotation and early volvulus. Unlike the classic symptoms seen in adults, young children can display only lethargy or poor feeding in cases of appendicitis or can appear happy and playful between paroxysmal bouts of intussusception. The emergency physician therefore, must maintain a high index of suspicion for serious pathology in pediatric patients with abdominal complaints. Eventually, all significant abdominal emergencies reveal their true nature, and if one can be patient with the child and repeat the examinations when the child is quiet, one will be rewarded with the correct diagnosis.

  13. Staged abdominal closure with intramuscular tissue expanders and modified components separation technique of a giant incisional hernia after repair of a ruptured omphalocele

    Yukihiro Tatekawa


    Full Text Available In patients with omphalocele, several different techniques are performed for repair of the abdominal wall defect. We present the case of a staged abdominal closure of a giant incisional hernia after repair of a ruptured omphalocele. At birth, skin flap coverage associated with silo formation occurred, but the abdominal wall defect remained, resulting in a giant abdominal hernia. To expand the layers of the abdominal wall, tissue expanders were placed between the bilateral internal oblique and transverses abdominis muscles. Postoperatively, a modified components separation technique was performed. The abdominal wall was closed in the midline. Upon closure of the skin in the midline, bilateral relaxing incisions were performed, covering the remaining defect with artificial dermis. At the age of one year and 7 months, the patient had no recurrent incisional hernia nor any wound complications.

    Full Text Available The present report describes a catastrophic penetrating abdominal injury associated with a roadside accident in a draught donkey. Though repair of the eviscerated, damaged portion of the small intestine was accomplished successfully, the animal could not be saved. After postmortem it was concluded that hypovolemia and respiratory distress resulted in the death of the wounded donkey before any resuscitating attempt could be made.

  15. Increased long-term mortality after a high perioperative inspiratory oxygen fraction during abdominal surgery

    Meyhoff, Christian Sylvest; Jorgensen, Lars N; Wetterslev, Jørn;


    A high perioperative inspiratory oxygen fraction (80%) has been recommended to prevent postoperative wound infections. However, the most recent and one of the largest trials, the PROXI trial, found no reduction in surgical site infection, and 30-day mortality was higher in patients given 80% oxygen....... In this follow-up study of the PROXI trial we assessed the association between long-term mortality and perioperative oxygen fraction in patients undergoing abdominal surgery....

  16. Dystrophies of the abdominal wall in adults: Surgical treatment

    Jayme Fortunato Athias


    Full Text Available The authors present a retrospective study of 60 patients with abdominal dystrophies, both with and without hernias, operated on in the period between 01 June 1994 and 30 January 1996. Their average age was 47 years. The incision at hernia itself and the dystrophic abdomen were the principal objects of the study. The authors show the importance of abdominal dermolipectomy for the complete recovery of the patient as well as demonstrate how it facilitates the technical manipulation of hernias. The technique of bilateral, longitudinal peritonio-aponeurotic transposition {the technique of Alcíno Lázaro da Silva was used for large incisional hernias. A variation of this technique, for hernias with a hernial ring of up to 10 cm, is proposed by the authors, which consists in the closing of the ring and the reinforcement of the suture with the hernial sac. A revision is made of the results of these procedures realized in isolation and accompanied with abdominal dermolipectomy. Forty-nine recovered without complications (81.66%, three relapsed (5%, one necrosis of the midline with respiratory failure (1.67%, one little stitch gap (1,67%, two umbilical stenosis (3,33%, two wound abscess (3.33%, one cutaneous fistula (1,67% and one death from pulmonary embolism (1.66%.

  17. Antinociceptive and wound healing activities of Croton adamantinus Müll. Arg. essential oil.

    Ximenes, Rafael Matos; de Morais Nogueira, Lenise; Cassundé, Nathalia Maria Rodrigues; Jorge, Roberta Jeane Bezerra; dos Santos, Simone Maria; Magalhães, Lucimere Paulino Machado; Silva, Monalisa Ribeiro; de Barros Viana, Glauce Socorro; Araújo, Renata Mendonça; de Sena, Kêsia Xisto da Fonseca Ribeiro; de Albuquerque, Julianna Ferreira Cavalcanti; Martins, René Duarte


    Leaves of Croton adamantinus have been used to treat inflammation and skin wounds in the semi-arid area of the Northeast of Brazil. In order to evaluate if the essential oil (EO) was responsible for the claimed activities; antinociceptive, wound healing and antimicrobial tests were carried out. Twenty constituents were identified in C. adamantinus EO by GC-MS, ¹H-NMR and ¹³C-NMR, the major compounds being methyl-eugenol (14.81%) and 1,8-cineol (13.74%). Antinociceptive activity was evaluated by the formalin test and the abdominal contortion assay in mice. The EO (50 and 100 mg/kg) decreased the licking time of both phases of the formalin test when compared to the vehicle, but not to morphine (7.5 mg/kg). In the abdominal contortion assay, the EO (50 and 100 mg/kg) reduced the number of contortions compared to the vehicle and to indometacin (10 mg/kg). The wound healing activity was verified also using two experimental models: excisional wound and dead space. Topical treatment with the EO (1%) increased the wound contraction from the third day of treatment (compared with nitrofurazone 0.2%), while systemic treatment (50 mg/kg/day) increased granulation tissue formation and reduced the water content. C. adamantinus EO also showed antimicrobial activity against Staphylococcus aureus in disk diffusion method. These results corroborate the ethnobotanical use of this specie by Brazilian population.

    HUANG Xian-kai; ZHU Yu-jun; ZHANG Lian-yang


    Objective: To investigate the application of damage control surgery in treatment of patients with severe thoracic and abdominal injuries.Methods: A retrospective study was done on 37 patients with severe thoracic and abdominal injuries who underwent damage control surgery from January 2000 to October 2006 in our department. There were 8 cases of polytrauma ( with thoracic injury most commonly seen), 21 of polytrauma (with abdominal injury most commonly seen) and 8 of single abdominal trauma. Main organ damage included smashed hepatic injuries in 17 cases,posterior hepatic veins injuries in 8, pancreaticoduodenal injuries in 7, epidural or subdural hemorrhage in 4,contusion and laceration of brain in 5, severe lung and bronchus injuries in 4, pelvis and one smashed lower limb wound in 3 and pelvic fractures and retroperitoneal hemorrhage in 6. Injury severity score (ISS) was 28-45 scores (38.4 scores on average), abbreviated injury scale (ALS) ≥ 4.13. The patients underwent arteriography and arterial embolization including arteria hepatica embolization in 4 patients, arteria renalis embolization in 2 and pelvic arteria retroperitoneal embolization in 7. Once abbreviated operation finished, the patients were sent to ICU for resuscitation. Twenty-four cases underwent definitive operation within 48 hours after initial operation, 5 underwent definitive operation within 72 hours after initial operation, 2 cases underwent definitive operation postponed to 96 hours after initial operation for secondary operation to control bleeding because of abdominal cavity hemorrhea.Two cases underwent urgent laparotomy and decompression because of abdominal compartment syndrome and 2 cases underwent secondary operation because of intestinal fistulae (1 case of small intestinal fistula and 1 colon fistula) and gangrene of gallbladder.Results: A total of 28 patients survived, with a survival rate of 75.68%, and 9 died (4 died within 24 hours and 5 died 3-9 days after injury).

  19. Development of a functional wound dressing composed of hyaluronic acid spongy sheet containing bioactive components: evaluation of wound healing potential in animal tests.

    Shimizu, Nahoko; Ishida, Daiki; Yamamoto, Akiko; Kuroyanagi, Misato; Kuroyanagi, Yoshimitsu


    This study aimed to develop a novel wound dressing composed of hyaluronic acid (HA) spongy sheet containing bioactive components. The wound dressing prepared by the freeze-drying method has a two-layered structure: an upper layer composed of cross-linked high-molecular-weight HA (HMW-HA) and a lower layer composed of low-molecular-weight HA (LMW-HA) containing arginine (Arg), magnesium ascorbyl phosphate (vitamin C derivative: VC), and epidermal growth factor (EGF) (referred to as EGF-dressing). A wound dressing containing only Arg and VC was prepared in a similar manner (referred to as EGF-free-dressing). The potential of each wound dressing was evaluated in animal tests using Sprague Dawley (SD) rats and diabetic mice. In the first experiment, each wound dressing was applied to a full-thickness skin defect in the abdominal region of SD rats. Wound conditions after 1 week and 2 weeks of treatment were evaluated based on macroscopic and histological appearance. A commercially available non-woven alginate wound dressing (Alg-dressing) was used in a control group. Both EGF-free-dressing and EGF-dressing decreased wound size and promoted granulation tissue formation associated with angiogenesis more effectively when compared with Alg-dressing. In particular, EGF-dressing promoted re-epithelialization. In the second experiment, each wound dressing was applied to a full-thickness skin defect in the dorsal region of diabetic mice. Wound conditions after 1 week and 2 weeks of treatment were evaluated based on macroscopic and histological appearance. A commercially available Alg-dressing was used in a control group. Both EGF-free-dressing and EGF-dressing decreased wound size and promoted granulation tissue formation associated with angiogenesis more effectively when compared with Alg-dressing. These findings indicate that EGF-free-dressing and EGF-dressing have the potential for more effective wound healing when compared with Alg-dressing. In particular, EGF-dressing has

    Chen, Jerry S; Longaker, Michael T; Gurtner, Geoffrey C


    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.

  6. Multimodal imaging of ischemic wounds

    Zhang, Shiwu; Gnyawali, Surya; Huang, Jiwei; Liu, Peng; Gordillo, Gayle; Sen, Chandan K.; Xu, Ronald


    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.

  7. Vasculogenic Cytokines in Wound Healing

    Victor W. Wong


    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.

  8. Microbial Biofilms and Chronic Wounds

    Omar, Amin; Wright, J. Barry; Schultz, Gregory; Burrell, Robert; Nadworny, Patricia


    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.

    Oya Uygur-Bayramicli; G(u)l Dabak; Resat Dabak


    AIM: To evaluate the clinical, radiological and microbiological properties of abdominal tuberculosis (TB) and to discuss methods needed to get the diagnosis.METHODS: Thirty-one patients diagnosed as abdominal TB between March 1998 and December 2001 at the Gastroenterology Department of Kartal State Hospital,Istanbul, Turkey were evaluated prospectively. Complete physical examination, medical and family history, blood count erythrocyte sedimentation rate, routine biochemical tests,Mantoux skin test, chest X-ray and abdominal ultrasonography (USG) were performed in all cases, whereas microbiological examination of ascites, upper gastrointestinal endoscopy, colonoscopy or barium enema, abdominal tomography, mediastinoscopy, laparoscopy or laparotomy were done when needed.RESULTS: The median age of patients (14 females, 17males) was 34.2 years (range 15-65 years). The most frequent symptoms were abdominal pain and weight loss.Eleven patients had active pulmonary TB. The most common abdominal USG findings were ascites and hepatomegaly. Ascitic fluid analysis performed in 13 patients was found to be exudative and acid resistant bacilli were present in smear and cultured only in one patient with BacTec (3.2 %). Upper gastrointestinal endoscopy yielded nonspecific findings in 16 patients. Colonoscopy performed in 20 patients showed ulcers in 9 (45 %), nodules in 2 (10 %)and, stricture, polypoid lesions, granulomatous findings in terminal ileum and rectal fistula each in one patient (5 %).Laparoscopy on 4 patients showed dilated bowel loops,thickening in the mesentery, multiple ulcers and tubercles on the peritoneum. Patients with abdominal TB were divided into three groups according to the type of involvement.Fifteen patients (48 %) had intestinal TB, L1 patients (35.2 %) had tuberculous peritonitis and 5 (16.8 %)tuberculous lymphadenitis. The diagnosis of abdominal TB was confirmed microbiologically in 5 (16 %) and histopathologically in 19 patients (60.8 %). The

  10. Use of Electrocautery for Coagulation and Wound Complications in Caesarean Sections

    Cristiane M. Moreira


    Full Text Available Objective. To evaluate the safety of electrocautery for coagulation during Caesarean sections. Study Design. A randomized, controlled, clinical pilot study was performed at a university maternity hospital. After admission for delivery and decision to perform a C-section, volunteers were randomized to either the intervention group (use of electrocautery for coagulation or nonintervention group. The women were examined at the time of postpartum discharge (day 3, at days 7 to 10, and again at days 30 to 40 for signs of infection, hematoma, seroma, or dehiscence. Data were analyzed using an intention-to-treat analysis, and risk ratios were calculated. Results. No significant differences were found between the two groups. Only 2.8% of patients in the intervention group developed surgical wound complications during hospitalization. However, 7 to 10 days following discharge, these rates reached 23.0% and 15.4% in the intervention and nonintervention groups, respectively (RR = 1.50, 95% CI = 0.84–2.60. Conclusion. Further studies should confirm whether the use of electrocautery for coagulation does not increase the risk of surgical wound complications in patients undergoing Caesarean sections.

  11. Trauma abdominal em grávidas Abdominal trauma in pregnant women

    Gustavo Pereira Fraga


    abdominal trauma and surgical treatment, from 1990 to 2002. Thirteen pregnant women with abdominal injury were identified. All cases were registered in the Epi-Info 6.04 protocol and data were analyzed statistically by the Fisher exact test, with confidence interval of 95%. RESULTS: ages ranged from 13 to 34 years (mean of 22.5. Six women (46.2% were in the third trimester of pregnancy. Penetrating trauma accounted for 53.8% of injuries and in six of these patients the mechanism of trauma was gunshot wounds. Three patients had uterine injuries associated with fetal death. There were no maternal deaths and fetal mortality was 30.7%. The use of trauma scores was not associated with maternal and fetal mortality. Uterine injury was the only predictive risk factor for fetal loss (p=0.014. CONCLUSIONS: this is a retrospective study analyzing a small number of pregnant women victims of severe trauma. However, the results show that there are no predictive accuracy scores to evaluate maternal and fetal outcomes.

    Morales Hernández, Sara; Díaz Velázquez, Mary Flor; Puello Tamara, Edgardo; Morales Hernández, Jorge; Basavilvazo Rodríguez, Maria Antonia; Cruz Cruz, Polita del Rocío; Hernández Valencia, Marcelino


    Abdominal pregnancies are the implantation of gestation in some of the abdominal structures. This kind of pregnancies represents sevenfold maternal death risk than tubarian ectopic pregnancies, and 90-fold death risk than normal ones. Previous cases have erroneously reported as abscess in Douglas punch, and frequently result in obitus or postnatal deaths. We report a case of a patient with 27 years old, and diagnosis of 25.2 weeks of pregnancy, prior placenta and anhidramnios, referred due to difficult in uterine contour delimitation, easy palpation of fetal parts, cephalic pole in left hypochondrious and presence of mass in hypogastria, no delimitations, pain with mobilization, no transvaginal bleed and fetal movements. Interruption of pregnancy is decided by virtue of severe oligohidramnios, retardation in fetal intrabdominal growth, and recurrent maternal abdominal pain. Surgical intervention was carried out for resolution of the obstetrical event, in which was found ectopic abdominal pregnancy with bed placental in right uterine horn that corresponded to a pregnancy of 30 weeks of gestation. Abdominal pregnancy is still a challenge for obstetrics due to its diagnosis and treatment. Early diagnosis is oriented to prevent an intrabdominal hemorrhage that is the main maternal cause of mortality.

  13. Evidence-based surgical wound care on surgical wound infection.

    Reilly, Jaqueline


    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.

    Hsu, Jui-Tse; Ho, Te-Wei; Shih, Hsueh-Fu; Chang, Chun-Che; Lai, Feipei; Wu, Jin-Ming


    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.

  15. 2017 update of the WSES guidelines for emergency repair of complicated abdominal wall hernias.

    Birindelli, Arianna


    Emergency repair of complicated abdominal wall hernias may be associated with worsen outcome and a significant rate of postoperative complications. There is no consensus on management of complicated abdominal hernias. The main matter of debate is about the use of mesh in case of intestinal resection and the type of mesh to be used. Wound infection is the most common complication encountered and represents an immense burden especially in the presence of a mesh. The recurrence rate is an important topic that influences the final outcome. A World Society of Emergency Surgery (WSES) Consensus Conference was held in Bergamo in July 2013 with the aim to define recommendations for emergency repair of abdominal wall hernias in adults. This document represents the executive summary of the consensus conference approved by a WSES expert panel. In 2016, the guidelines have been revised and updated according to the most recent available literature.

  16. The external microenvironment of healing skin wounds.

    Kruse, Carla R; Nuutila, Kristo; Lee, Cameron C Y; Kiwanuka, Elizabeth; Singh, Mansher; Caterson, Edward J; Eriksson, Elof; Sørensen, Jens A


    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.

  17. Abdominal wall hernia and pregnancy

    Jensen, K K; Henriksen, N A; Jorgensen, L N


    PURPOSE: There is no consensus as to the treatment strategy for abdominal wall hernias in fertile women. This study was undertaken to review the current literature on treatment of abdominal wall hernias in fertile women before or during pregnancy. METHODS: A literature search was undertaken in Pub......Med and Embase in combination with a cross-reference search of eligible papers. RESULTS: We included 31 papers of which 23 were case reports.

No major complications were reported following hernia repair before or during pregnancy. The combined procedure of elective cesarean section and abdominal wall hernia repair was reported...

  18. Abdominal actinomycosis mimicking acute appendicitis.

    Conrad, Robert Joseph; Riela, Steven; Patel, Ravi; Misra, Subhasis


    A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

  19. Comparison of silver nylon wound dressing and silver sulfadiazine in partial burn wound therapy.

    Abedini, Fereydoon; Ahmadi, Abdollah; Yavari, Akram; Hosseini, Vahid; Mousavi, Sarah


    The study aims to perform a comparative assessment of two types of burn wound treatment. 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.

  20. Wound repair in Pocillopora

    Rodríguez-Villalobos, Jenny Carolina; Work, Thierry M.; Calderon-Aguileraa, Luis Eduardo


    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.

  1. Recent advances in topical wound care.

    Sarabahi, Sujata


    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.

  2. Effects of platelet-poor plasma, platelet-rich plasma, and platelet-rich fibrin on healing of extraction sockets with buccal dehiscence in dogs.

    Hatakeyama, Ichiro; Marukawa, Eriko; Takahashi, Yukinobu; Omura, Ken


    Alveolar bone resorption generally occurs during healing after tooth extraction. This study aimed to evaluate the effects of platelet-poor plasma (PPP), platelet-rich plasma (PRP), and platelet-rich fibrin (PRF) on healing in a ridge-augmentation model of the canine socket with dehiscence of the buccal wall. The third mandibular premolars of 12 beagle dogs were extracted and a 3 mm buccal dehiscence from the alveolar crest to the buccal wall of the extraction socket was created. These sockets were then divided into four groups on the basis of the material used to fill the sockets: PPP, PRP, PRF, and control (no graft material) groups. Results were evaluated at 4 and 8 weeks after surgery. The ultrastructural morphology and constructs of each blood product were studied by a scanning electron microscope (SEM) or calculating concentrations of platelets, fibrinogen, platelet-derived growth factor, and transforming growth factor-β. A total of five microcomputed tomography images of specimens were selected for measurement, and the area occupied by the newly formed bone as well as the horizontal bone width were measured. Moreover, decalcified tissue specimens from each defect were analyzed histologically. The median area of new bone at 4 and 8 weeks and median horizontal bone width at 8 weeks were the highest in the PPP group. However, bone maturation in the PRF and the PRP groups was more progressed than that in the PPP and control groups. By SEM findings, the PRF group showed a more highly condensed fibrin fiber network that was regularly arranged when compared with the PPP and PRP groups. The growth factors released from platelets in PRP indicated higher concentrations than that in PRF. Under more severe conditions for bone formation, as in this experiment, the growth factors released from platelets had a negative effect on bone formation. This study showed that PPP is an effective material for the preservation of sockets with buccal dehiscence.

  3. A comparision of two types of decalcified freeze-dried bone allograft in treatment of dehiscence defects around implants in dogs

    Ahmad Moghareh Abed


    Full Text Available Background: Decalcified freeze-dried bone allograft (DFDBA may have the potential to enhance bone formation around dental implants. Our aim in this study was the evaluation and comparison of two types of DFDBA in treatment of dehiscence defects around Euroteknika® implants in dogs. Methods : In this prospective clinical trial animal study, all mandibular premolars of three Iranian dogs were extracted. After 3 months of healing, fifteen SLA type Euroteknika® dental implants (Natea with 4.1mm diameter and 10mm length were placed in osteotomy sites with dehiscence defects of 5mm length, 4 mm width, and 3mm depth. Guided bone regeneration (GBR procedures were performed using Cenobone and collagen membrane for six implants, the other six implants received Dembone and collagen membrane and the final three implants received only collagen membrane. All implants were submerged. After 4 months of healing, implants were uncovered and stability (Implant Stability Quotient of all implants was measured. Then, block biopsies of each implant site were taken and processed for ground sectioning and histomorphometric analysis. The data was analyzed by ANOVA and Pearson tests. P value less than 0.05 was considered to be significant. Results: All implants osseointegrated after 4 months. The mean values of bone to implant contact for histomorphometric measurements of Cenobone, Denobone, and control groups were 77.36 ± 9.96%, 78.91 ± 11.9% and 71.56 ± 5.61% respectively, with no significant differences among the various treatment groups. The correlation of Implant Stability Quotient and histomorphometric techniques was 0.692. Conclusion: In treating of dehiscence defects with GBR technique in this study, adding DFDBA did not significantly enhance the percentages of bone-to-implant contact measurements; and Implant Stability Quotient Resonance Frequency Analysis appeared to be a precise technique.

  4. CT appearances of abdominal tuberculosis

    Lee, W.-K., E-mail: [Department of Medical Imaging, St Vincent' s Hospital, University of Melbourne, Fitzroy, Victoria (Australia); Van Tonder, F.; Tartaglia, C.J.; Dagia, C.

[Department of Radiology, Norris Comprehensive Cancer Center, University of Southern California, Los Angeles, California (United States); Chang, S.D. [Department of Medical Imaging, Vancouver General Hospital, University of British Columbia, British Columbia (Canada)


    The purpose of this article is to review and illustrate the spectrum of computed tomography (CT) appearances of abdominal tuberculosis. Tuberculosis can affect any organ or tissue in the abdomen, and can be mistaken for other inflammatory or neoplastic conditions. The most common sites of tuberculosis in the abdomen include lymph nodes, genitourinary tract, peritoneal cavity and gastrointestinal tract. The liver, spleen, biliary tract, pancreas and adrenals are rarely affected, but are more likely in HIV-seropositive patients and in miliary tuberculosis. This article should alert the radiologist to consider abdominal tuberculosis in the correct clinical setting to ensure timely diagnosis and enable appropriate treatment.

  5. Blunt abdominal trauma in sports.

    Rifat, Sami F; Gilvydis, Rimas P


    Abdominal injuries are rare in sports, but when they do occur it is important that the physician recognize the warning signs of potentially life-threatening injury to the liver, spleen, or hollow abdominal viscera. Though the sports medicine physician may not always provide definitive treatment of many of these conditions, he or she should be familiar with the preferred diagnostic modalities and latest treatment options. This information is not only essential to appropriately participate in treatment decisions, but is also important in order to make return-to-play determinations.

  6. [Gallstone ileus. Abdominal CT usefulness].

    Sukkarieh, F; Brasseur, P; Bissen, L


    The authors report the case of a 93-year old woman referred to the emergency department and presenting with an intestinal obstruction. Abdominal CT reveals a biliary ileus caused by the migration and the impaction of a 3 cm gallstone in the small bowel. Surgical treatment by enterolithotomy was successful. In over 90% of cases, gallstone ileus is a complication of cholelithiasis and accounts for 25% of intestinal obstruction in patients over 65 years. To reduce morbidity and mortality, early diagnosis and prompt treatment are essential. Abdominal CT-scan is the gold standard technique.

  7. Forces driving epithelial wound healing

    Brugués, Agustí; Anon, Ester; Conte, Vito; Veldhuis, Jim H.; Gupta, Mukund; Colombelli, Julien; Muñoz, José J.; Brodland, G. Wayne; Ladoux, Benoit; Trepat, Xavier


    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.

  9. Gunshot wounds to the lower urinary tract: A single-institution experience

    Cinman, Nadya M.; McAninch, Jack W.; Porten, Sima P.; Myers, Jeremy B.; Blaschko, Sarah D.; Bagga, Herman S.; Breyer, Benjamin N.


    BACKGROUND This study aimed to analyze characteristics and outcomes of gunshot wounds to the lower urinary tract at our Level I trauma center. Our hypothesis is that gunshot wounds to the lower urinary tract have characteristic bullet trajectories, injury patterns, and associated injuries. METHODS Our prospective trauma database was composed of reviewed gunshot wounds to the lower urinary tract including the pelvic ureter, bladder, or urethra from 1989 through 2011. RESULTS We identified 50 patients (median age, 25 years; range, 3–53 years) with lower urinary tract injury. There was a mean of 2.3 bullets per patient (range, 1–8), with 26 patients injured from a single bullet. Urologic injury involving only the bladder occurred in 72% (36 of 50) of the patients. Ureteral injury was diagnosed in 20% (10 of 50) of the patients. Bullet trajectory was known in the majority of multiple bullet injuries and all cases involving a single bullet. All patients but one were managed operatively. During exploration, 90% (34 of 38) with transmural bladder injury had recognized bladder entry and exit wounds. Overall, 80% (40 of 50) had concurrent gastrointestinal injury. In patients with a single gunshot wound to the lower urinary tract, 58% (15 of 26) sustained concomitant intestinal injury, and 23% (6 of 26) sustained rectal injury. Of 20 posteroanterior gunshot wounds, 80% had buttock entry. All 10 single-bullet buttock-entry gunshot wounds injured the bladder. Isolated ureteral injury was associated with lower abdominal entry and anteroposterior trajectory. Urethral injury occurred in 4, with 75% upper-thigh entry. CONCLUSION Penetrating injuries to the lower urinary tract most commonly involve the bladder. During exploration for gunshot wounds to the bladder, two injury sites should be expected because failure to close may lead to complications. Gunshot wounds to the lower urinary tract often occur with concomitant bowel injury, with buttock entry. A multidisciplinary

  10. 浅谈正畸与骨开窗骨开裂%Preliminary recognition of orthodontics and bony dehiscences and fenestrations

    刘怡; 李小彤; 韩劼


    Orthodontic treatment is based on the teeth root movement in aveolar bone,the ability and scope of movement affect treatment results.Traditionally,there is no method to evaluate aveolar bone three dimensionally,and no orthodontic requirement to evaluate bony dehiscences and fenestrations.In recent years,CBCT gives opportunity to examine alveolar bone three dimensionally,more and more orthodontic researches focused on bony dehiscences and fenestrations,which cause much attention and doubtfulness.There is no exact definition of bony dehiscences and fenestrations,also no 3D diagnostic criteria were established by now.Orthodontists need to recognize bony dehiscences and fenestrations comprehensively.We should establish orthodontic diagnostic standard and,at the same time,improve our treatment accuracy to avoid periodontal impairment.%正畸治疗基于牙根在牙槽骨内的移动来完成,牙根的移动能力与范围决定了正畸治疗效果.传统正畸诊断与评价手段不能对牙槽骨的三维完整性做出准确的评价,也不要求在正畸治疗前去评价和诊断骨开窗骨开裂.随着近些年三维影像技术的发展,尤其是锥形束CT在口腔科的广泛应用,三维评价牙槽骨成为可能,越来越多的正畸研究开始报告正畸患者治疗前后均有骨开窗骨开裂的发生,引起许多质疑和担心.本文希望向读者阐明,骨开窗与骨开裂影像诊断仍缺少标准,需要区别认识解剖发育异常与组织缺陷的骨开窗与骨开裂.三维正畸诊断技术需要不断提高,最终建立骨开窗与骨开裂的正畸诊断标准,同时正畸治疗也需要更精确规范,避免不必要的牙周损害.

  11. Gunshot wounds: epidemiology, wound ballistics, and soft-tissue treatment.

    Dougherty, Paul J; Najibi, Soheil; Silverton, Craig; Vaidya, Rahul


    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.

    Background The techniques of resection and repair of large lesions in the abdominal wall are very challenging in the area of gynecology.We explored the techniques of resection and plastic surgical repair of large abdominal wall lesions in gynecologic patients.Methods Twenty-six patients with large lesions in the abdominal wall underwent resection by the gynecologists and repair through abdominal plasty and V-Y plasty with or without fascia patch grafting by the gynecologists or plastic surgeons from March 2003 to October 2010.Results All patients had a history of cesarean section.One patient had an infected sinus tract after cesarean section,one patient had an inflammatory nodule,and the others had lesions of endometriosis,including one cancer.The average largest lesion diameter was (4.79 ± 4.18) cm according to the ultrasonography results.The lesions of all patients were completely resected with pretty abdominal contour.A polypropylene biological mesh was added to the fascia in 20 patients.One patient underwent groin flap repair,and one underwent V-Y advanced skin flap repair on the left of the incision to relieve the suture tension.Conclusions Multi-department cooperation involving the gynecology and plastic surgery departments,and even the general surgery department,is essential for patients with large lesions in the abdominal wall.This cooperative effort enabled surgeons to completely resect large lesions.Abdominal wall plastic surgical repair can ameliorate large wounds of the abdominal wall.

  13. Transarterial coil embolization in treatment of gross hematuria following self-inflicted stab wound in a horseshoe kidney

    Masoud Pezeshki Rad; Hassan Ahmadnia; Mahboobeh Abedi; Mohammad Sadegh Abedi


    Horseshoe kidney is an uncommon anomaly of the urinary system with an increased risk of injury during penetrating and blunt abdominal traumas.Selfinflicted abdominal stab wound,a rare type of abdominal injury,accounts for only a small percentage of suicidal attempts and may be infrequently encountered by physicians in trauma centers.Psychiatric disorders and alcohol or drug abuse are common risk factors in cases of self-stabbing.Here we report a rare case of self-stabbing of a horseshoe kidney.The case was a 19-year-old man with self-inflicted abdominal stab wound who was referred to our department of radiology due to re-occurred gross hematuria three days after exploratory laparotomy and surgical repair of injured abdominal organs.A horseshoe kidney was incidentally found in the patient's abdominal computed tomography.Renal angiography revealed active contrast extravasation from one of the segmental arteries.Selective transarterial embolization with a coil was successfully performed to control the hematuria.

    The natural history of typhoid fever poses both a diagnostic and a therapeutic challenge. Awareness of the clinical features of the primary presentation and of the complications are pivotal to early diagnosis. Typically, aggressive supportive care is all that is needed. However abdominal complications do occur and proper surgical care is required to lower morbidity and mortality.

    Fraccalvieri, Doménico; Kreisler Moreno, Esther; Flor Lorente, Blas; Torres García, Antonio; Muñoz Calero, Alberto; Mateo Vallejo, Francisco; Biondo, Sebastiano


    The aim of this study is to evaluate the usefulness of Vicryl Plus(®) suture in reducing the rate of postoperative wound infection in elective colorectal surgery. A prospective case-control multicenter study with 480 patients undergoing elective colorectal surgery was performed between 2006 and 2007. Patients were divided in 2 groups of equal sample size: group 1, closure of the abdominal wall using Vicryl Plus(®) and group 2 where PDS II(®) was used. The study involved 5 hospitals in the Spanish State. Wound infection was classified into superficial and deep. All patients diagnosed of wound infection during the hospital stay and up to 30 days after discharge were studied. For the statistical analysis Chi-square test and Fisher exact were used for bivariate analysis and logistic regression model for multivariate analysis. Wound infection rates were significantly lower in group 1: 14.6 vs. 29.2. Multivariate analysis showed that risk of wound infection was higher in patients with cancer, lung disease, anemia, operative time greater than 2 h, lack of second dose intra-operative prophylactic antibiotic and laparotomy closure with PDS suture II(®). The use of suture coated with triclosan can be an effective prophylactic tool in reducing wound infection rate in patients undergoing elective colorectal surgery. Copyright © 2013 AEC.

  18. Photobiomodulation in promoting wound healing: a review.

    Kuffler, Damien P


    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.

  19. [Nursing management of wound care pain].

    Chin, Yen-Fan


    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.

  20. Determining injuries from posterior and flank stab wounds using computed tomography tractography.

    Bansal, Vishal; Reid, Chris M; Fortlage, Dale; Lee, Jeanne; Kobayashi, Leslie; Doucet, Jay; Coimbra, Raul


    Unlike anterior stab wounds (SW), in which local exploration may direct management, posterior SW can be challenging to evaluate. Traditional triple contrast computed tomography (CT) imaging is cumbersome and technician-dependent. The present study examines the role of CT tractography as a strategy to manage select patients with back and flank SW. Hemodynamically stable patients with back and flank SW were studied. After resuscitation, Betadine- or Visipaque®-soaked sterile sponges were inserted into each SW for the estimated depth of the wound. Patients underwent abdominal helical CT scanning, including intravenous contrast, as the sole abdominal imaging study. Images were reviewed by an attending radiologist and trauma surgeon. The tractogram was evaluated to determine SW trajectory and injury to intra- or retroperitoneal organs, vascular structures, the diaphragm, and the urinary tract. Complete patient demographics including operative management and injuries were collected. Forty-one patients underwent CT tractography. In 11 patients, tractography detected violation of the intra- or retroperitoneal cavity leading to operative exploration. Injuries detected included: the spleen (two), colon (one), colonic mesentery (one), kidney (kidney), diaphragm (kidney), pneumothorax (seven), hemothorax (two), iliac artery (one), and traumatic abdominal wall hernia (two). In all patients, none had negative CT findings that failed observation. In this series, CT tractography is a safe and effective imaging strategy to evaluate posterior torso SW. It is unknown whether CT tractography is superior to traditional imaging modalities. Other uses for CT tractography may include determining trajectory from missile wounds and tangential penetrating injuries.

  1. Negative Pressure Wound Therapy in Maxillofacial Applications

    Adam J. Mellott


    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.

    Scalise, Alessandro; Tartaglione, Caterina; Bolletta, Elisa; Calamita, Roberto; Nicoletti, Giovanni; Pierangeli, Marina; Grassetti, Luca; Di Benedetto, Giovanni


    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.

  7. Postoperative washing of sutured wounds

    Conrad Harrison


    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.

  8. A prospective, controlled evaluation of the abdominal reapproximation anchor abdominal wall closure system in combination with VAC therapy compared with VAC alone in the management of an open abdomen.

    Long, Kristin L; Hamilton, David A; Davenport, Daniel L; Bernard, Andrew C; Kearney, Paul A; Chang, Phillip K


    Dramatic increases in damage control and decompressive laparotomies and a significant increase in patients with open abdominal cavities have resulted in numerous techniques to facilitate fascial closure. We hypothesized addition of the abdominal reapproximation anchor system (ABRA) to the KCI Abdominal Wound Vac™ (VAC) or KCI ABThera™ would increase successful primary closure rates and reduce operative costs. Fourteen patients with open abdomens were prospectively randomized into a control group using VAC alone (control) or a study group using VAC plus ABRA (VAC-ABRA). All patients underwent regular VAC changes; patients receiving VAC-ABRA also underwent concomitant daily elastomer adjustment of the ABRA system. Primary end points included abdominal closure, number of operating room (OR) visits, and OR time use. Eight patients were included in the VAC-ABRA group and six patients in the control group. Primary closure rates between groups were not statistically different; however, the number of trips to the OR and OR time use were different. Despite higher Acute Physiology and Chronic Health Evaluation II scores, larger starting wound size, and higher rates of abdominal compartment syndrome, closure rates in the VAC-ABRA group were similar to VAC alone. Importantly, however, fewer OR trips and less OR time were required for the VAC-ABRA group.

  9. Abdominal Compartment Syndrome: pathophysiology and definitions

    Cheatham Michael L


    Abstract "Intra-abdominal hypertension", the presence of elevated intra-abdominal pressure, and "abdominal compartment syndrome", the development of pressure-induced organ-dysfunction and failure, have been increasingly recognized over the past decade as causes of significant morbidity and mortality among critically ill surgical and medical patients. Elevated intra-abdominal pressure can cause significant impairment of cardiac, pulmonary, renal, gastrointestinal, hepatic, and central nervous ...

  11. A Primer on Wound Bed Preparation

    Gokoo, Chuck


    Successful wound closure and healing are a major concern for today's clinician. Determining if the wound will progress or not relies on a comprehensive assessment, recognition of wound characteristics that will promote or impede the healing process and preparing the wound bed such that pathological features are removed allowing the healing cascade to occur. When complications are no longer a roadblock the wound will achieve a stable microenvironment and progress through the normal repairative...

  12. Hyperbaric oxygen and wound healing

    Sourabh Bhutani


    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.

  13. Overexpression of rice black-streaked dwarf virus p7-1 in Arabidopsis results in male sterility due to non-dehiscent anthers.

    Feng Sun

    Full Text Available Rice black-streaked dwarf virus (RBSDV, a member of the genus Fijivirus in the family Reoviridae, is propagatively transmitted by the small brown planthopper (Laodelphax striatellus Fallén. RBSDV causes rice black-streaked dwarf and maize rough dwarf diseases, which lead to severe yield losses in crops in China. Although several RBSDV proteins have been studied in detail, the functions of the nonstructural protein P7-1 are still largely unknown. To investigate the role of the P7-1 protein in virus pathogenicity, transgenic Arabidopsis thaliana plants were generated in which the P7-1 gene was expressed under the control of the 35S promoter. The RBSDV P7-1-transgenic Arabidopsis plants (named P7-1-OE were male sterility. Flowers and pollen from P7-1-transgenic plants were of normal size and shape, and anthers developed to the normal size but failed to dehisce. The non-dehiscent anthers observed in P7-1-OE were attributed to decreased lignin content in the anthers. Furthermore, the reactive oxygen species levels were quite low in the transgenic plants compared with the wild type. These results indicate that ectopic expression of the RBSDV P7-1 protein in A. thaliana causes male sterility, possibly through the disruption of the lignin biosynthesis and H2O2-dependent polymerization pathways.

  14. Delayed dehiscence of the pericarp: role in germination and retention of viability of seeds of two cold desert annual Brassicaceae species.

    Lu, J J; Tan, D Y; Baskin, C C; Baskin, J M


    Considerable variation occurs in post-maturity timing of dehiscence in fruits of Brassicaceae species, and several studies have shown that the pericarp plays an important role in seed germination and retention of viability in species with indehiscent fruits. However, little is known about the significance to seed biology of delay in pericarp dehiscence for seed germination and retention of seed viability. We compared dormancy-break via after-ripening in the laboratory and germination phenology and retention of seed viability in intact siliques and isolated seeds buried in an experimental garden. Seeds of both species have Type 6 non-deep physiological dormancy, which is enhanced by the pericarp. Seeds of both species after-ripened during summer 2013, and some of them germinated in autumn and some in the following spring in watered and non-watered soil. Germination percentages of seeds in siliques increased in soil in spring 2014, after the pericarps had opened. Most isolated seeds of L. filifolium and N. korolkovii had germinated or were dead by spring 2014 and summer 2015, respectively, whereas 60% of the seeds of both species in the (opened) pericarps were viable after 24 months. Thus, although the pericarp opened 9-10 months after burial, its presence had a significant effect on seed dormancy, germination phenology and retention of viability of seeds of L. filifolium and N. korolkovii. © 2016 German Botanical Society and The Royal Botanical Society of the Netherlands.

    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.

  20. Topical oxygen wound therapies for chronic wounds: a review.

    Dissemond, J; Kröger, K; Storck, M; Risse, A; Engels, P


    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.
