    This paper presents a conceptual framework which outlines the risk factors associated with surgical wound dehiscence (SWD) as identified in the literature. The purpose for the development of the conceptual framework was to derive an evidence-based, informed understanding of factors associated with SWD, in order to inform a programme of research on the aetiology and potential risk factors of SWD. Incorporated within the patient-centric conceptual framework are patient related comorbidities, intraoperative and postoperative risk factors related to SWD. These are categorised as either 'mechanical' or 'physiological mechanisms' posited to influence these relationships. The use of the conceptual model for assessment of patients has particular clinical relevance for identification of risk and the management of patients in the pre-, intra- and postoperative period.

    Surgical wound dehiscence (SWD) increases the length of hospital stay and impacts on patient wellbeing and health-care costs. Globally, the health-care costs associated with SWD are poorly reported and those reported are frequently associated with surgical site infection (SSI), rather than dehiscence of non-microbial cause. This retrospective study describes and reports on the costs and time to healing associated with a number of surgical patients who were referred to a community nursing service for treatment of an SWD following discharge from a metropolitan hospital, in Perth, Western Australia. Descriptive statistical analysis was carried out to describe the patient, wound and treatment characteristics. A costing analysis was conducted to investigate the cost of healing these wounds. Among the 70 patients referred with a SWD, 55% were treated for an infected wound dehiscence which was a significant factor (p=0.001). Overall, the cost of treating the 70 patients with a SWD in a community nursing service was in excess of $56,000 Australian dollars (AUD) (£28,705) and did not include organisational overheads or travel costs for nurse visits. The management of infection contributed to 67% of the overall cost. SWD remains an unquantified aspect of wound care from a prevalence and fiscal point of view. Further work needs to be done in the identification of SWD and which patients may be 'at risk'. The authors declare they have no competing interests.

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

    Full Text Available BACKGROUND The aim of the study is to- 1. Assess the association and prevalence of risk factors involved in causing post laparotomy wound dehiscence. 2. Identify the type of disease involved in causing abdominal wound dehiscence. 3. Effectively manage cases of wound dehiscence. MATERIALS AND METHODS Total 50 cases clinically presenting as gaping of abdominal wound and discharge from the site during the period of October 2014 to April 2016 were taken for study. Patients presenting with abdominal wound dehiscence after undergoing elective or emergency operation Each case was examined clinically and properly in systematic manner and an elaborative study of history based on chief complaints, significant risk factors, investigations, time and type of surgery performed and postoperative events and day of onset of wound dehiscence. RESULTS Males outnumbered females with 64% males and 36% females. Patients in the age group of 41-50 years and 51-60 years found to have highest incidence of abdominal wound dehiscence. Mean age of the patients affected was 48.02 years. Incidence of abdominal wound dehiscence is more common in patients with peritonitis due to duodenal and appendicular perforation than in case of intestinal obstruction. Incidence of abdominal wound dehiscence is more common in patients who are operated in emergency than elective (35:15. Surgical procedures, which included perforation closure carried higher incidence of wound dehiscence. Patients operated with midline incision carried higher risk for wound dehiscence than those operated with paramedian incisions. Incidence of abdominal wound dehiscence is more common in patients having their BMI >25 and anaemia (Hb% <10 g%. Average stay was 22 days, which increased both economic burden on patient and hospital. Out of 50 cases, 48 survivals and 2 were mortals. Partial wound dehiscence was conservative management, i.e. healing by secondary intention was observed in 32 patients and 8 patients had

    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.

    Full Text Available INTRODUCTION: Wound dehiscence is described as partial or complete disruption of an abdominal wound closure with or without protrusion and evisceration of abdominal contents. It is a very serious postopera tive complication associated with high mortality and morbidity. This study is aimed , to identify significant risk factors in patients developing abdominal wound dehiscence . T o identify the diseases involved in the development of wound dehiscence. To study the type of incision leading to wound dehiscence. To study the incidence of wound dehiscence in elective and emergency operation. MATERIALS & METHODS: A Clinical Study has been conducted at Department of General Surgery, MVJ Medical College and Research Ho spital, Bangalore, India. On patients admitted from November 2012 to May 2015, who underwent routine and emergency laparotomies and developed abdominal wound dehiscence. 57 consecutive patients undergoing laparotomy were included. RESULTS: A total of 57 pa tients who developed wound dehiscence were included in the study. In them 40(70% cases had the disaster occurring in emergency procedures (p<0.0001 (Table no 3 in subgroup of emergency laparotomies incidence was highest in cases of midline incision (P<0 .001, it was the commonly used incision. CONCLUSION: Wound sepsis associated with intra - abdominal abscess is the single most important risk factor for wound dehiscence. Factors like anemia, malnutrition, obesity, emergency surgeries for peritonitis due to bowel perforation add on to it, as factors which helped in developing wound dehiscence

    Full Text Available Spontaneous wound separation may be developed even months after suture removal especially in the context of long-term corticosteroid therapy. A 68-year-old 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.

    To report the frequency of lateral wound dehiscence (LWD) after upper blepharoplasty (UB), a technique and its outcome to prevent LWD. A retrospective review was performed for cases of LWD after UB presenting between 2003 and 2009, and then a prospective comparative study was performed between February 2009 and March 2013. For the comparison, subjects were divided into two groups based on intraoperative assessment of lateral wound tension (same technique and surgeon). Group 1 received 1-3 orbicularis/subcutaneous buried sutures (6-0 polyglactin) before interrupted 6-0 nylon skin closure. Group 2 underwent skin closure only. Subjects, who had re-operation, skin healing disorders, and incomplete follow-up (LWD with a mean age of 36.2 years in the audit (2003-2009). The prospective study included 68 subjects (68/293, 23.2%) in Group 1 and 225 in Group 2. Gender and simultaneous forehead and eyebrow procedures were similar between groups (P = 0.3 and P = 0.4 respectively). Group 1 was statistically significantly younger at mean age of 41.4 years, compared to Group 2 at 56.1 years (P = 0.000). The frequency of LWD significantly (P = 0.04) decreased to 0.3% (1/293). In the presence of wound tension on skin closure (intraoperative assessment), tension relieving buried orbicularis/subcutaneous 6-0 polyglactin suturing of the lateral UB incision could prevent LWD.

    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.

    Full Text Available We present a rare case with gossypiboma following cesarean section which led to uterine wound dehiscence. A 30-year-old woman had been submitted to an emergency cesarean section 4 months previously at another hospital. Clinical and ultrasound findings revealed a large intra-abdominal mass and diffuse peritonitis. At laparotomy, a gossypiboma causing an abscess and uterine wound dehiscence with necrosis of the margins was detected. We performed repetitive wound debridements under broad-spectrum antibiotic cover and eventually resutured the incision. Although hysterectomy has so far been the choice of treatment in the literature once a uterine wound dehiscence had occurred, it was possible in this case to preserve the uterus.

    The results achieved on the clinical assay, which took place on the 'Miguel Enrique' Surgical and Clinical Hospital, are presented. The main objective is to evaluate the therapeutic efficacy of the equipment for laser physiotherapy Fisser 21, over the healing of dehiscent wounds after the aesthetic surgery, comparing them with the most common treatment with antibiotics. All data obtained between two groups were analyzed, the first one with laser therapy (21 patients), and the other one with conventional treatment (18 patients). Taking into account such comparison, the dependence of the speed of reduction of the dehiscence width from the time of healing of this kind of wounds is proposed. (Author)

    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.

    Objective: To find out the frequency of abdominal wound dehiscence (AWD) in a tertiary care hospital and the assessment of associated risk factors. Subjects and Methods: This study was carried out on 406 patients who underwent laparotomy for intra peritoneal procedure and complied with inclusion criteria. Demographic features were recorded and any complications documented. Results: Out of a total of 406 patients, 32 showed wound dehiscence giving an over all frequency of 7.8%. The male to female ratio was 2.8:1. The frequency was greater in males than in females. Majority patients suffered from an underlying malignancy. Malignant intestinal obstruction was the leading cause of wound dehiscence. Forty three patients had hypoalbuminemia(serum albumin <35 gm/l) and 09 of them had AWD. Emergency surgery showed a higher frequency of AWD(12.5%), as compared to elective surgery (18/143 and 14/263 respectively). Wound infection was a major contributor to AWD as out of 406, 76 patients developed infection and then 21 manifested AWD. Older age was also associated with greater frequency. The overall mortality of AWD in this study was 28.1 %. Conclusion: AWD still continues to be major post operative complication, with a high morbidity and mortality. The significant risk factors in this study were age more than 55 years, male gender, underlying malignancy, wound infection, jaundice, use of steroids, emergency surgery, uraemia and technique of closure.

    To report a complication pertaining to subconjunctival bevacizumab injection as an adjunct to Ahmed Glaucoma Valve (AGV) implantation. A 54-year-old woman with history of complicated cataract surgery was referred for advanced intractable glaucoma. AGV implantation with adjunctive subconjunctival bevacizumab (1.25 mg) was performed with satisfactory results during the first postoperative week. However, 10 days after surgery, she developed wound dehiscence and tube exposure. The second case was a 33-year-old man with history of congenital glaucoma and uncontrolled IOP who developed AGV exposure and wound dehiscence after surgery. In both cases, for prevention of endophthalmitis and corneal damage by the unstable tube, the shunt was removed and the conjunctiva was re-sutured. The potential adverse effect of subconjunctival bevacizumab injection on wound healing should be considered in AGV surgery.

    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.

    The objectives of this study were to: (1) document the incidence of surgical site dehiscence after full-thickness gastrointestinal biopsy in dogs and cats and (2) identify potential risk factors. Data relating to dogs and cats undergoing full-thickness gastrointestinal biopsy were reviewed retrospectively following submission of a completed questionnaire by 12 referral institutions. Outcome measures were definite dehiscence, possible dehiscence (clinical records suggestive of dehiscence but not confirmed), suspected dehiscence (definite and possible combined) and death within 14 days. Logistic regression was planned for analysis of association of dehiscence with low preoperative serum albumin, biopsy through neoplastic tissue, biopsy alongside another major abdominal surgical procedure and biopsy of the colon. Of 172 cats, two (1·2%) had definite dehiscence, and four (2·3%) had possible dehiscence. Low preoperative serum albumin was significantly associated with definite dehiscence in univariable analysis and with suspected dehiscence and death within 14 days in univariable analysis, but all odds ratios had wide 95% confidence intervals. A histopathological diagnosis of neoplasia was significantly associated with death within 14 days in univariable analysis. Of 195 dogs, two (1·0%) had definite dehiscence, and three (1·5%) had possible dehiscence. In dogs, there was no association between any outcome measure and the putative risk factors. Incidence of dehiscence following full-thickness gastrointestinal biopsy was low in this study. When determining the appropriateness of biopsy in individual cases, this information should be balanced against the potentially life-threatening consequences of dehiscence. © 2017 British Small Animal Veterinary Association.

    We describe a case of recipient bed melt and wound dehiscence after uneventful penetrating keratoplasty and subconjunctival injection of bevacizumab. Three weeks postoperatively, the patient presented with limbal ischemia, recipient bed melt, and wound dehiscence corresponding to the area of bevacizumab injection. The melt was managed by application of cyanoacrylate glue along with bandage contact lens. Although the graft survived, there was a problem in re-epithelization. This case highlights the need for further studies to elucidate the therapeutic dose, side effects, and correct timing of using bevacizumab with respect to corneal transplant surgery.

    The purpose of this study was to investigate the periodontal healing pattern of dehiscence-type defects following different chemical root conditioning modalities. Buccal osseous dehiscence defects were created on six teeth of seven dogs. After dental plaque accumulation, defects were treated with sterile saline solution (control group) or one chemical conditioning modality: citric acid (CA group), ethylenediaminetetraacetic acid (EDTA group), tetracycline (TTC group), citric acid + tetracycline (CA + TTC group), or tetracycline + citric acid (TTC + CA group). After 3 months of healing, clinical parameters were evaluated, and the animals were killed. Histological sections were processed, and a computer-assisted histometric analysis was used to evaluate the formation of new cementum, new bone, and epithelial apical migration. All treatments yielded significant improvements in terms of probing depth decrease and clinical attachment level gain compared to baseline values; however, without significant differences among the groups (p > 0.05; one-way ANOVA). The highest amount of new cementum was noted in the EDTA group (3.72 ± 0.83 mm, 77.6 %), while the lowest amount of new bone was observed in the TTC group (0.7 ± 0.94 mm, 14.3 %). However, no statistically significant differences could be observed among the groups regarding epithelial apical migration, new cementum, and alveolar bone formation (p > 0.05). Chemical root surface conditioning did not promote any significant improvement in periodontal healing pattern of dehiscence-type defects in dogs. Chemical root surface conditioning after surgical debridement did not promote positive or negative effects on periodontal healing pattern of dehiscence-type defects.

    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.

    Increasing age has traditionally been associated with impairment in wound healing after operative interventions. This is based mostly on hearsay and anecdotal information. This idea fits with the authors’ understanding of biology in older organisms. This dictum has not been rigorously tested in clinical practice. The American College of Surgeons National Surgical Quality Improvement Program database was retrospectively queried for all patients undergoing plastic surgery from 2005 to 2010. Variables extracted included basic demographics, comorbidities, previous steroid and tobacco use, wound classification at the end of the surgery, and development of postoperative surgical-site infections. Multivariate analyses were used to investigate the impact of aging in wound dehiscence. A total of 25,967 patients were identified. Overall, the incidence of wound dehiscence was 0.75 percent (n = 196). When patients younger than 30 years were compared to older patient groups, no difference in the probability of developing wound dehiscence was noted. Specifically, the groups of patients aged 61 to 70 years and older than 70 years did not have statistically significant wound healing deficiencies [adjusted OR, 0.63 (95 percent CI, 0.11 to 3.63), adjusted p = 0.609; 2.79 (0.55 to 14.18), adjusted p = 0.217, for 61 to 70 years and older than 70 years, respectively]. Factors independently associated with wound dehiscence included postoperative abscess development, paraplegia, quadriplegia, steroid and tobacco use, deep surgical-site infection development, increasing body mass index, and wound classification at the end of surgery. In patients undergoing plastic surgery, wound dehiscence is a rare complication (0.75 percent). Aging is not associated with an increased incidence of wound dehiscence. Risk, III.

    Low-velocity gunshot wounds cause most civilian duodenal injuries. The objective of this study was to describe a simplified surgical algorithm currently in use in a South African civilian trauma center and to verify its validity by measuring morbidity and mortality. A retrospective chart review of patients with duodenal gunshot injuries during the study period January 1999 to December 2003 was performed. Data points accrued included patient demographics, admission hemodynamic status and resuscitative measures, laparotomy damage control procedures, methods of surgical repair of the duodenal injury, associated injuries, length of intensive care and hospital stays, complications, and mortality. A total of 75 consecutive patients with gunshot injuries to the duodenum were reviewed. Primary repair was performed in 54 patients (87%), resection and reanastomosis in 7 (11%), and pancreatoduodenectomy in 1 (2%) during the initial phases. The overall morbidity and mortality were 58% and 28%, respectively. Duodenum-related complications were recorded in nine (15%) patients: two duodenal fistulas, one duodenal obstruction, and six cases of suture-line dehiscence. Overall and duodenum-related morbidity rates in patients with combined pancreatoduodenal injuries were 83% and 17%, respectively. Duodenum-related mortality occurred in three (4.8%) patients. Most civilian low-velocity duodenal gunshot injuries treated with simple primary repair result in overall morbidity, mortality, and duodenum-related complication rates comparable to those in reports where more complex surgical procedures were employed. Primary repair is also applicable for most combined pancreatic and duodenal gunshot injuries.

    During the period between January 1996 and July 1998 in our department 1920 patients were operated on account of heart disease from median sternotomy. In 17 patients, i.e. in 0.9% during the early postoperative period the surgical wound disintegrated incl. dehiscence of the sternum and the development of postoperative mediastinitis. In 14 of these patients the authors reconstructed the defect of the thoracic wall by their own modification of Jurkiewicz plastic operation using the pectoral muscles. One patient from this group died, in the remaining 13 patients the wound healed without deformity of the chest and without signs of instability, without restriction of movement and function.

    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.

    Full Text Available BACKGROUND AND OBJECTIVE: It is an established fact now that the normal skin of healthy human beings harbours a rich bacterial fl ora. Normally considered non - pathogenic , these organisms way be a potential source of infection of the surgical wound. Approximately 20% of the resident flora is beyond the reach of surgical scrubs and antiseptics. The goal of surgical preparation of the skin with antiseptics is to remove transient and pathogenic microorganisms on the skin surface and to reduce the resident flora to a low level. Povidone iodine (I odophors and chlorhexidine are most often used antiseptics for pre - operative skin preparation. OBJECTIVES : To evaluate the efficacy of povidone iodine alone and in combination with antiseptic agent containing alcoholic chlorhexidine in preoperative skin p reparation by taking swab culture. (2 To compare the rate of postoperative wound infection in both the groups. METHODS: One hundred patients (fifty in each group undergoing clean elective surgery with no focus of infection on the body were included in th e study. The pre - operative skin preparation in each group is done with the respective antiseptic regimen. In both the groups after application of antiseptics , sterile saline swab culture was taken immediately from site of incision. In cases which showed gr owth of organisms , the bacteria isolated were identified by their morphological and cultural characteristics. Grams staining , coagulase test and antibiotic sensitivity test were done wherever necessary and difference in colonization rates was determined as a measure of efficacy of antiseptic regimen. RESULTS: The results of the study showed that when compared to povidone iodine alone , using a combination of povidone iodine and alcoholic solution of chlorhexidine , the colonization rates of the site of incisi on were reduced significantly. As for the rate of post - operative wound infection , it is also proven that wound infections are also

    . RESULTS: Ten studies met the inclusion criteria, reporting on 1311 incisions in 1089 patients. NPWT was associated with a significant reduction in wound infection (relative risk (RR) 0·54, 95 per cent c.i. 0·33 to 0·89) and seroma formation (RR 0·48, 0·27 to 0·84) compared with standard care....... The reduction in wound dehiscence was not significant. The numbers needed to treat were three (seroma), 17 (dehiscence) and 25 (infection). Methodological heterogeneity across studies led to downgrading of the quality of evidence to moderate for infection and seroma, and low for dehiscence. CONCLUSION: Compared...

    Full Text Available Objectives The aim of the study was to investigate the effects of age and/or surgical approach on perioperative wound complication following ovariohysterectomy (OHE. Methods A retrospective search of perioperative monitoring records from a shelter desexing program was conducted to identify cats that underwent OHE between 1 June 2010 and 31 December 2012 inclusive. A wound complication was defined as gross observation of inflammation or wound dehiscence at the surgical site in the 5 day postoperative period. Cases were grouped according to age (≤12 weeks or >12 weeks and surgical approach (flank or midline. Stratified analyses were conducted to evaluate the association between surgical approach and wound complications, after adjusting for age. Mantel–Haenszel adjusted risk ratio, Cochran–Mantel–Haenszel test statistic and their 95% confidence intervals were presented. Results A total of 312 cases met the study criteria. The overall wound complication risk was low (6.09% and was not related to age. A midline approach was associated with a 4.59-times increased risk of wound complication, compared with a flank approach in cats up to 12 weeks of age ( P = 0.015 but not in older cats. Conclusions and relevance These findings support the practice of prepubertal desexing for cats.

    early versus delayed dressing removal. We excluded trials that included people with contaminated or dirty wounds. We also excluded quasi-randomised studies, and other study designs. Two review authors independently extracted data on the characteristics of the trial participants, risk of bias in the trials and outcomes for each trial. We calculated risk ratios (RR) with 95% confidence intervals (CI) for binary outcomes and mean difference (MD) with 95% CI for continuous outcomes. We used RevMan 5 software to perform these calculations. Four trials were identified for inclusion in this review. All the trials were at high risk of bias. Three trials provided information for this review. Overall, this review included 280 people undergoing planned surgery. Participants were randomised to early dressing removal (removal of the wound dressing within the 48 hours following surgery) (n = 140) or delayed dressing removal (continued dressing of the wound beyond 48 hours) (n = 140) in the three trials. There were no statistically significant differences between the early dressing removal group and delayed dressing removal group in the proportion of people who developed superficial surgical site infection within 30 days (RR 0.64; 95% CI 0.32 to 1.28), superficial wound dehiscence within 30 days (RR 2.00; 95% CI 0.19 to 21.16) or serious adverse events within 30 days (RR 0.83; 95% CI 0.28 to 2.51). No deep wound infection or deep wound dehiscence occurred in any of the participants in the trials that reported this outcome. None of the trials reported quality of life. The hospital stay was significantly shorter (MD -2.00 days; 95% CI -2.82 to -1.18) and the total cost of treatment significantly less (MD EUR -36.00; 95% CI -59.81 to -12.19) in the early dressing removal group than in the delayed dressing removal group in the only trial that reported these outcomes. The early removal of dressings from clean or clean contaminated surgical wounds appears to have no detrimental effect on

    The incidence of fascial dehiscence and incisional hernia after two methods for abdominal wound closure (rectus sheath relaxation incisions and conventional mass closure) was studied in a randomized prospective clinical trial in a consecutive series of 100 patients undergoing midline laparotomy for peritonitis. The two groups were well matched for etiologies of peritonitis, the surgical procedures performed, and the presence of known risk factors for fascial dehiscence. Fifty patients each were randomized either to the conventional continuous mass closure procedure or the rectus sheath relaxation incision technique (designed to increase wound elasticity and decrease tension in the suture line) using identical polypropylene sutures. The incidence of postoperative complications such as duration of ileus, chest infection, and wound infection were not statistically different between the two groups. The intensity of postoperative pain in the rectus sheath relaxation incision group was significantly less. The incidence of wound hematoma was significantly increased in the rectus sheath relaxation incision group. The incidences of fascial dehiscence (16% vs,28%; p cases of peritonitis using the rectus sheath relaxation technique is safe and less painful, provides increased wound elasticity and decreased tension on the suture line, and significantly decreases the incidence of wound dehiscence.

    Discussion: The design of the herein-described modified surgical wound dressing is based on a butterfly shaped adhesive and mirrors the advantages of a modern surgical wound dressing. Its shape is suitable for the physiological structure of the neck, making it more comfortable to use. Aseptic packaging and a high degree of adhesiveness guarantee continuous fixation and pulling. At the same time, the design of the dressing decreases the chance of infection.

    Full Text Available Non-healing wounds continue to be a clinical challenge for patients and medical staff. These wounds have a heterogeneous etiology, including diabetes and surgical trauma wounds. It is therefore important to decipher molecular signatures that reflect the macroscopic process of wound healing. To this end, we collected wound sponge dressings routinely used in vacuum assisted therapy after surgical trauma to generate wound-derived protein profiles via global mass spectrometry. We confidently identified 311 proteins in exudates. Among them were expected targets belonging to the immunoglobulin superfamily, complement, and skin-derived proteins, such as keratins. Next to several S100 proteins, chaperones, heat shock proteins, and immune modulators, the exudates presented a number of redox proteins as well as a discrete neutrophil proteomic signature, including for example cathepsin G, elastase, myeloperoxidase, CD66c, and lipocalin 2. We mapped over 200 post-translational modifications (PTMs; cysteine/methionine oxidation, tyrosine nitration, cysteine trioxidation to the proteomic profile, for example, in peroxiredoxin 1. Investigating manually collected exudates, we confirmed presence of neutrophils and their products, such as microparticles and fragments containing myeloperoxidase and DNA. These data confirmed known and identified less known wound proteins and their PTMs, which may serve as resource for future studies on human wound healing.

    Background Surgical site infections (SSIs) are wound infections that occur after an operative procedure. A preventable complication, they are costly and associated with poorer patient outcomes, increased mortality, morbidity and reoperation rates. Surgical wound irrigation is an intraoperative technique, which may reduce the rate of SSIs through removal of dead or damaged tissue, metabolic waste, and wound exudate. Irrigation can be undertaken prior to wound closure or postoperatively. Intracavity lavage is a similar technique used in operations that expose a bodily cavity; such as procedures on the abdominal cavity and during joint replacement surgery. Objectives To assess the effects of wound irrigation and intracavity lavage on the prevention of surgical site infection (SSI). Search methods In February 2017 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE; Ovid Embase and EBSCO CINAHL Plus. We also searched three clinical trials registries and references of included studies and relevant systematic reviews. There were no restrictions on language, date of publication or study setting. Selection criteria We included all randomised controlled trials (RCTs) of participants undergoing surgical procedures in which the use of a particular type of intraoperative washout (irrigation or lavage) was the only systematic difference between groups, and in which wounds underwent primary closure. The primary outcomes were SSI and wound dehiscence. Secondary outcomes were mortality, use of systemic antibiotics, antibiotic resistance, adverse events, re-intervention, length of hospital stay, and readmissions. Data collection and analysis Two review authors independently assessed studies for inclusion at each stage. Two review authors also undertook data extraction, assessment of risk of bias and GRADE assessment. We calculated risk ratios or differences in means with 95% confidence intervals where

    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.

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.

    Chronic wounds may occur or persist due to arterial insufficiency. Despite the high prevalence of arterial occlusive disease, a search of the literature has yielded a paucity of data on the benefit of interventions to recanalise lower extremity arteries prior to surgical closure of chronic wounds. To investigate the correlation of simple clinical examinations and apparative diagnostics for the detection of arterial occlusive disease of the lower extremity in patients with chronic wounds, and to evaluate the benefit of vascular procedures to optimise wound perfusion before surgical closure. During a 6-year period, 150 patients with chronic lower extremity wounds (no healing for more than 30 days) were included into this prospective study. All patients underwent palpation of foot pulses, Doppler sonography and measurement of occlusive pressures. Positive clinical findings were re-evaluated by angiography. All patients with peripheral extremity vessel occlusions underwent vascular interventions (percutaneous transluminal angioplasty with stenting, open thrombectomy or vascular bypass surgery) prior to surgical wound closure. In all 34 patients (21%) with missing foot pulses, suspicious Doppler signals or pathological occlusive pressure measurements, the clinical diagnosis of arterial occlusion was confirmed by angiography. An arterial pathology had previously been diagnosed in merely two of those patients. Nineteen patients underwent percutaneous transluminal angioplasty and 21 stents were implanted; in 10 cases, open thrombectomy or vascular bypasses were performed. In all 34 patients, sufficient peripheral recanalisation and improved wound perfusion were successfully achieved. For definitive wound closure, microsurgical tissue transplantation was performed in 15 patients. Angiography was performed prior to surgery. In 11 patients, regional or local flaps were used. Six patients received split skin grafting only; two wounds healed conservatively following vascular

    Introduction: In Brazil, the main cause of death is the coronary heart disease and the surgical treatment applied in such cases is the Myocardial Revascularization (MR). Patients undergoing to MR through saphenous vein bypass development dehiscence in 10% of the cases. Dehiscence of surgical incision through Biomodulation treatment with Low Level Laser Therapy (LLLT) in patients who underwent to MR seems to be an unprecedented new therapy and a less invasive technique, which can benefit patients and Institutions, reducing costs. Methodology: It was analyzed 7 diabetic patients, mean age 51, 8 years old that post MR surgery presented dehiscence of the saphenectomy incision on lower limb with erithema, edema and pain. The wounds area varies from 2,2 until 34,8 cm and deep from 0,1 until 1,1 cm. It was used only Diode Laser C.W. (655 nm wavelength), Power = 25 mW, Time = 30 s, Fluence = 4 J/cm2 applied punctually around surgical wound's sore, by 2 cm distance. Results: It was observed granulated tissue all around the incision, as well as decreased inflammatory process, reduction fibrin and wound's size, besides analgesic effect since the first application. It was required in superficial wounds only 3 applications, while in the extensive wounds 8-10 applications were necessary. The LLLT has shown a remarkable role as a wound healing facilitated agent, reflecting the reduction of inflammatory process and improving analgesia. Conclusion: LLLT assisted dehiscence post saphenectomy showed a substantial improvement to the patient's quality of life, with a cost-effectiveness treatment that can benefit both patients and Institutions as an effective and less invasive therapy.

    Full Text Available Objective: To evaluate the correlation between wound cosmesis and pet owner satisfaction, to determine the agreement among vet surgeons, and pet owners evaluating a surgical wound with a visual assessment score (VAS, and to determine the agreement between the VAS, a semi-quantitative score of wound inflammation, and wound width.Background: Perception of post-surgical cosmesis by human patients has been found to influence their satisfaction and perceived adequacy of vet surgeons. Due to the trend of owners anthropomorphising pets, this logic can be extended to veterinary patients. Also, there is a lack of consistent, reliable methods to evaluate cosmesis have been developed, creating the need for a scoring system that is accurate and reproducible.Evidentiary value: This was a prospective cohort study with one hundred and seven patients. This study may not change day-to-day practices, but it will bring to light for practitioners the discordance between pet owners and vet surgeons concerning attractiveness of an incision as well as overall satisfaction with a procedure.Methods: Photographs of surgical wounds were taken immediately, 2 weeks, and 8 weeks after surgery in dogs. Owners were asked to evaluate satisfaction with the procedure and attractiveness of the incision using the VAS. Photos were evaluated for cosmetic outcome by pet owner and vet surgeon evaluators with different scoring systems. The reliability of the scoring systems was evaluated using intraclass correlations and kappa statistics as appropriate.Results:  Owners’ evaluation of cosmetic outcome correlated with their overall satisfaction. (r2=0.37, where r2 is the coefficient of determination, and can be used to determine what proportion of variance in one variable is predictable from the other variableThere was generally poor reliability of the subjective scoring between both vet surgeons and pet owners, and the less subjective scoring systems.Conclusion: The cosmetic outcome

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

    Directory of Open Access Journals (Sweden)

    Allyson Lipp

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

    Endogenous JA production is not necessary for wound-induced expression of JA-biosynthetic lipase genes such as DAD1 in Arabidopsis. However, the JA-Ile receptor COI1 is often required for their JA-independent induction. Wounding is a serious event in plants that may result from insect feeding and increase the risk of pathogen infection. Wounded plants produce high amounts of jasmonic acid (JA), which triggers the expression of insect and pathogen resistance genes. We focused on the transcriptional regulation of DEFECTIVE IN ANTHER DEHISCENCE1 and six of its homologs including DONGLE (DGL) in Arabidopsis, which encode lipases involved in JA biosynthesis. Plants constitutively expressing DAD1 accumulated a higher amount of JA than control plants after wounding, indicating that the expression of these lipase genes contributes to determining JA levels. We found that the expression of DAD1, DGL, and other DAD1-LIKE LIPASE (DALL) genes is induced upon wounding. Some DALLs were also expressed in unwounded leaves. Further experiments using JA-biosynthetic and JA-response mutants revealed that the wound induction of these genes is regulated by several distinct pathways. DAD1 and most of its homologs other than DALL4 were fully induced without relying on endogenous JA-Ile production and were only partly affected by JA deficiency, indicating that positive feedback by JA is not necessary for induction of these genes. However, DAD1 and DGL required CORONATINE INSENSITIVE1 (COI1) for their expression, suggesting that a molecule other than JA might act as a regulator of COI1. Wound induction of DALL1, DALL2, and DALL3 did not require COI1. This differential regulation of DAD1 and its homologs might explain their functions at different time points after wounding.

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

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

    Vacuum-assisted closure (VAC) therapy is a new emerging non-invasive system in wound care, which speeds up wound healing by causing vacuum, improving tissue perfusion and suctioning the exudates, and facilitating the removal of bacteria from the wound. The application of sub-atmospheric pressure on the lesions seems to alter the cytoskeleton of the cells on the wound bed, triggering a cascade of intracellular signals that increase the rate of cell division and subsequent formation of granulation tissue. The aim of this study is to analyse the results of VAC therapy used as an adjuvant therapy for the treatment of foot wounds in patients affected by critical limb ischaemia (CLI) (Rutherford 6 class) after distal surgical revascularisation, to promote and accelerate the healing of ulcers. Twenty-nine patients (20 males, 9 females; mean age 68·4) affected by CLI of Rutherford 6 class, after surgical revascularisation of the lower limb, underwent VAC therapy in order to speed up wound healing. Complete wound healing was achieved in 19 patients (65·51%), in an average period of 45·4 ± 25·6 days. VAC therapy is a valid aid, after surgical revascularisation, to achieve rapid healing of foot lesions in patients with CLI. © 2014 The Authors.

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

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

  20. Traffic in the operating room: a review of factors influencing air flow and surgical wound contamination.

    Science.gov (United States)

    Pokrywka, Marian; Byers, Karin

    2013-06-01

    Surgical wound contamination leading to surgical site infection can result from disruption of the intended airflow in the operating room (OR). When personnel enter and exit the OR, or create unnecessary movement and traffic during the procedure, the intended airflow in the vicinity of the open wound becomes disrupted and does not adequately remove airborne contaminants from the sterile field. An increase in the bacterial counts of airborne microorganisms is noted during increased activity levels within the OR. Researchers have studied OR traffic and door openings as a determinant of air contamination. During a surgical procedure the door to the operating room may be open as long as 20 minutes out of each surgical hour during critical procedures involving implants. Interventions into limiting excessive movement and traffic in the OR may lead to reductions in surgical site infections in select populations.

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

    Directory of Open Access Journals (Sweden)

    Ann Katharin Reckhenrich

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

    Deep sternal wound infections (DSWIs) are a rare but serious complication after median sternotomy, and treatment success depends mainly on surgical experience. We compared treatment outcomes after conventional sternal rewiring and reconstruction with no sternal rewiring in patients with a sternal wound infection. We retrospectively enrolled patients who developed a DSWI after an open-heart procedure with median sternotomy at the Department of Cardiac Surgery, at the St. Rafael Hospital, Zalaegerszeg, Hungary, between 2012 and 2016. All patients received negative pressure wound and antibiotic therapy before surgical reconstruction. Patients were divided into groups determined by the reconstruction technique and compared. Subjects were followed up for 12 months, and the primary end-points were readmission and 90-day mortality. Among 3,177 median sternotomy cases, 60 patients developed a DSWI, 4 of whom died of sepsis before surgical treatment. Fifty-six patients underwent surgical reconstruction with conventional sternal rewiring (23 cases, 41%) or another interventions with no sternal refixation (33 cases, 59%). Eighty-one percent of sternal wound infections followed coronary bypass surgery (alone or combinated with another procedures), and 60% were diagnosed after hospital discharge. Staphylococcus aureus was cultured in 30% of all wounds and, 56.5% of cases reconstructed by sternal rewiring vs. 26.5% with no sternal rewiring, (P=0.022). Hospital readmission occurred in 63.6% of the sternal rewiring group vs. 14.7% of the no sternal rewiring group. The rate of death before wound healing or the 90 th postoperative day was 21.7% in the sternal rewiring group vs. 0% in the no sternal rewiring group. The median hospital stay was longer in the sternal rewiring group than in the other group (51 vs. 30 days, P=0.006). Sternal rewiring may be associated with a higher rate of treatment failure than other forms of treatment for sternal wound infections.

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

    The aim of this study was to compare the efficacy of vacuum assisted closure (VAC) with standard moist wound care (SMWC) in surgical site infection after ankle surgery. A prospective cohort was performed among patients with surgical site infection after ankle surgery between 2012 and 2013. The follow-up period was three month, and the efficacy end point was complete wound closure rate. Ninety-four patients were analyzed, with 61 patients in the VAC group and 33 in the SMWC group. The complete wound closure rate in the VAC group was higher than that in the SMWC group at 3 month follow up (90.2% Vs. 72.7%, p = 0.028). The median time to complete wound closure was 31 days (95% CI 20.2-41.8) for VAC, and 63 days (95% CI 46.9-79.1) for SMWC (χ(2) = 4.023, p = 0.045). In the superficial infection subgroup, the median times to complete wound closure were 20 days (95% CI 14.2-35.1) in the VAC group and 42 days (95% CI 35.4-69.4) in SMWC group (χ(2) = 4.331, p = 0.041). In the deep subgroup, the median times to complete wound closure were 46 days (95% CI 28.2-65.9) in the VAC group and 75 days (95% CI 43.2-79.6) in SMWC group (χ(2) = 6.475, p = 0.026). Our result showed that vacuum assisted closure was more effective than standard moist wound care in surgical site infection after ankle surgery. Copyright © 2015 IJS Publishing Group Limited.

    Surgical wounds in diabetic patients still remain a problem till the present day. As a common plant found around the world, Hypericum perforatum L. (Hypericaceae) is traditionally prepared as an oily extract and used as a folk remedy for various diseases such as wounds, burns, cuts, etc. This study aims to evaluate the effect of St. John's wort (Hypericum perforatum) on problematic wounds while comparing oral and topical applications. Incisional and excisional wound models were made on the dorsal regions of 54 diabetic Spraque-Dawley rats. The rats were divided into the following six groups (n = 9): Group 1: control, Group 2: diabetic, Group 3: diabetic oral Hypericum perforatum, Group 4: diabetic topical Hypericum perforatum, Group 5: diabetic oral olive oil, and Group 6: diabetic topical olive oil. Groups 3 and 4 had significantly higher tensile strength, tissue hydroxyproline concentration, and collagen density compared with Group 2. Inflammatory cell density and collagen density on day 3 were significantly higher in Groups 3 and 6 compared with Group 2. On day 21, Groups 3 and 6 had significantly higher fibroblastic activity compared with Group 2. This study has proved that oral St. John's wort has more positive effects on problematic wounds compared with topical St. John's wort and olive oil, which is a vehicle. Hypericum perforatum results with faster inflammatory response and better healing. These results could be an addition to literature about the clinical usage of Hypericum perforatum on diabetic wounds.

    Full Text Available Introduction. The advantages of laparoscopic removal of a myoma over classical surgical technique are shorter hospital stay, rapid recovery and less pain after surgery, as well as a lower frequency of ileus and thromboembolic complications. The surgical technique of laparoscopic removal of myoma involves four basic stages: incision on the wall of the uterus, separation of the myoma from the healthy uterine tissue, to stop bleeding and removal of the myoma from the abdomen. Apart from these four basic stages, it is also necessary to establish a new integrity of the uterine wall, especially in women planning pregnancy. Objective. The aim of the paper is to present the procedures used in the treatment of uterine wall defect during the laparoscopic removal of the myoma. Methods. We analyzed 96 patients who were indicated for laparoscopic myomectomy. All patients were divided into four groups according to the type of the technique of haemostasis and treatment of the defect on the uterine wall: electrocoagulation, electrocoagulation with application of argon plasma, a single suture and extended suture. Results. In order to stop bleeding, we most often used electrocoagulation by monopolar electricity, i.e. in 39.6% of the patients. To stop bleeding and treat the defect of the uterine wall, we used a single suture in 21.9% and in 11.4% patients we used the extended suture. The manner of uterine wall treatment did not have a statistically significant influence on the results of haematological parameters (p>0.05, consumption of carbon dioxide (p>0.05 and the duration of surgical procedure (p>0.05. The increased use of antibiotics (p<0.05 in the group of patients in whom we treated the defect by sutures on the uterus, the length of postsurgical hospitalization and absence from work (p<0.01 was statistically significant. Conclusion. To achieve a better reconstruction of the uterus, it is recommended to use sutures with laparoscopic removal of myoma.

    To investigate the effect of a baking soda-hydrogen peroxide (0.75%) dentifrice on wound healing, plaque formation, gingival inflammation, patient comfort, probing depth, and clinical attachment level following gingival flap surgery. A randomized, double-blind crossover study involving 25 patients requiring bilateral maxillary gingival flap surgery was completed. The effects of twice daily brushing with a baking soda-hydrogen peroxide dentifrice (Mentadent) or a placebo dentifrice (Crest) were observed over a 28-day post-surgical period. Gingival Index (GI), plaque index (PI), probing depth (PD), clinical attachment level (CAL) and gingival bleeding index (BI) were recorded pre-surgically and at day 28 for each surgical sextant. At days 7 and 14, soft tissue appearance/wound healing (STA) was assessed based on color and edema, PIs were determined and patient comfort was ascertained by report. Post-surgical wound healing was statistically significantly improved at day 7 with the trend continuing to day 14 when Mentadent dentifrice was used as compared to Crest dentifrice. However, there was no statistical difference in the PI values between the test and control dentifrice throughout the study. Use of Mentadent may be an effective aid in the early phase of healing following gingival flap surgery.

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

    Surgical drain tube readings can influence the clinical management of the post-operative patient. The accuracy of these readings has not been documented in the current literature and this experimental study aims to address this paucity. Aliquots (10, 25, 40 and 90 mL) of black tea solution prepared to mimic haemoserous fluid were injected into UnoVac, RedoVac and Jackson-Pratt drain tubes. Nursing and medical staff from a tertiary hospital were asked to estimate drain volumes by direct observation; analysis of variance was performed on the results and significance level was set at 0.05. Doctors and nurses are equally accurate in estimating drain tube volumes. Jackson-Pratt systems were found to be the most accurate for intermediate volumes of 25 and 40 mL. For extreme of volumes (both high and low), all drainage systems were inaccurate. This study suggests that for intermediate volumes (25 and 40 mL), Jackson-Pratt is the drainage system of choice. The accuracy of volume measurement is diminished at the extremes of drain volumes; emptying of drainage systems is recommended to avoid overfilling of drainage systems. © 2014 Royal Australasian College of Surgeons.

    Post-operative cognitive dysfunction (POCD) is associated with morbidity, mortality and increased cost of medical care. However, the neuropathogenesis and targeted interventions of POCD remain largely to be determined. We have found that the peripheral surgical wounding induces an age-dependent A? accumulation, neuroinflammation and cognitive impairment in aged mice. Pro-inflammatory cytokine interlukin-6 (IL-6) has been reported to be associated with cognitive impairment in rodents and human...

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

    Most surgical wounds heal by primary intention, that is to say, the edges of the wound are brought together with sutures, staples, adhesive glue or clips. However, some wounds may be left open to heal (if there is a risk of infection, or if there has been significant tissue loss), and are known as 'surgical wounds healing by secondary intention'. They are estimated to comprise approximately 28% of all surgical wounds and are frequently complex to manage. However, they are under researched and little is known of their impact on patients' lives. To explore patients' views and experiences of living with a surgical wound healing by secondary intention. A qualitative, descriptive approach. Participants were recruited from acute and community nursing services in two locations in the North of England characterised by high levels of deprivation and diverse populations. Participants were aged 18 years or older and had at least one surgical wound healing by secondary intention, which was slow to heal. Purposeful sampling was used to include patients of different gender, age, wound duration and type of surgery (general, vascular and orthopaedic). Twenty people were interviewed between January and July 2012. Semi-structured interviews were conducted, guided by use of a topic guide developed with input from patient advisors. Data were thematically analysed using steps integral to the 'Framework' approach to analysis, including familiarisation with data; development of a coding scheme; coding, charting and cross comparison of data; interpretation of identified themes. Alarm, shock and disbelief were frequently expressed initial reactions, particularly to "unexpected" surgical wounds healing by secondary intention. Wound associated factors almost universally had a profound negative impact on daily life, physical and psychosocial functioning, and wellbeing. Feelings of frustration, powerlessness and guilt were common and debilitating. Patients' hopes for healing were often

    The SHAM Insurance Company in Lyon, France, estimated that inadequate hand wound exploration in the emergency room (ER) accounted for 10% of all ER-related personal injury claims in 2013. The objective of this study was to conduct a critical analysis of 80 claims that were related to hand wound management in the ER and led to compensation by SHAM. Eighty claims filed between 2007 and 2010 were anonymised then included into the study. To be eligible, claims had to be filed with SHAM, related to the ER management of a hand wound in an adult, and closed at the time of the study. Claims related to surgery were excluded. For each claim, we recorded 104 items (e.g., epidemiology, treatments offered, and impact on social and occupational activities) and analysed. Of the 70 patients, 60% were manual workers. The advice of a surgeon was sought in 16% of cases. The most common wound sites were the thumb (33%) and index finger (17%). Among the missed lesions, most involved tendons (74%) or nerves (29%). Many patients had more than one reason for filing a claim. The main reasons were inadequate wound exploration (97%), stiffness (49%), and dysaesthesia (41%). One third of patients were unable to return to their previous job. Mean sick-leave duration was 148 days and mean time from discharge to best outcome was 4.19%. Most claims (79%) were settled directly with the insurance company, 16% after involvement of a public mediator, and 12% in court. The mean compensatory damages award was 4595Euros. Inadequate surgical exploration of hand wounds is common in the ER, carries a risk of lasting and sometimes severe residual impairment, and generates considerable societal costs. IV.

    To investigate the efficacy of a 10% gel of unripe banana (Musa sapientum) peel in treating surgical wounds in rats. A longitudinal, prospective, randomized triple-blind study was conducted with 60 Wistar rats (Rattus norvegicus albinus) weighing approximately 400g. The animals were randomly divided into: control group (treated with gel containing no active ingredient) and study group (treated with 10% gel of unripe banana peel). The gel was applied every three days to a 4x4-cm surgical wound created on the back of each animal (day 0) in both groups. Tissue samples were collected for histological analysis on days 14, 21 and 28. On day 14, more extensive vascular proliferation (p=0.023), presence of mononuclear cells (p=0.000), fibroblast proliferation (p=0.012), re-epithelialization (p=0.000), and decreased presence of polymorphonuclear cells (p=0.010) were observed in the study group than in controls. No significant between-group difference in the presence of polymorphonuclear cells was found on day 21. Fibroblast proliferation was significantly greater (p=0.006) in the study group than in the control group on day 28. The 10% gel of unripe banana peel showed anti-inflammatory activity and stimulated wound healing in rat skin when compared with a gel containing no active ingredient.

    Full Text Available The replacement of single anterior teeth by means of endosseous implants implies the achievement of success in restoring both aesthetic and function. However, the presence of wide endoperiodontal lesions can lead to horizontal hard and soft tissues defects after tooth extraction, making it impossible to correctly place an implant in the compromised alveolar socket. Vertical augmentation procedures have been proposed to solve these clinical situations, but the amount of new regenerated bone is still not predictable. Furthermore, bone augmentation can be complicated by the presence of adjacent teeth, especially if they bring with them periodontal defects. Therefore, it is used to restore periodontal health of adjacent teeth before making any augmentation procedures and to wait a certain healing period before placing an implant in vertically augmented sites, otherwise risking to obtain a nonsatisfactory aesthetic result. All of these procedures, however, lead to an expansion of treatment time which should affect patient compliance. For this reason, this case report suggests a surgical technique to perform vertical bone augmentation at a single gap left by a central upper incisor while placing an implant and simultaneously to regenerate the periodontal attachment of an adjacent lateral incisor, without compromising the aesthetic result.

    Non surgical wounds include chronic ulcers (pressure or decubitus ulcers, venous ulcers, diabetic ulcers, ischaemic ulcers), burns and traumatic wounds. The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) colonisation (i.e. presence of MRSA in the absence of clinical features of infection such as redness or pus discharge) or infection in chronic ulcers varies between 7% and 30%. MRSA colonisation or infection of non surgical wounds can result in MRSA bacteraemia (infection of the blood) which is associated with a 30-day mortality of about 28% to 38% and a one-year mortality of about 55%. People with non surgical wounds colonised or infected with MRSA may be reservoirs of MRSA, so it is important to treat them, however, we do not know the optimal antibiotic regimen to use in these cases. To compare the benefits (such as decreased mortality and improved quality of life) and harms (such as adverse events related to antibiotic use) of all antibiotic treatments in people with non surgical wounds with established colonisation or infection caused by MRSA. We searched the following databases: The Cochrane Wounds Group Specialised Register (searched 13 March 2013); The Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2); Database of Abstracts of Reviews of Effects (2013, Issue 2); NHS Economic Evaluation Database (2013, Issue 2); Ovid MEDLINE (1946 to February Week 4 2013); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, March 12, 2013); Ovid EMBASE (1974 to 2013 Week 10); EBSCO CINAHL (1982 to 8 March 2013). We included only randomised controlled trials (RCTs) comparing antibiotic treatment with no antibiotic treatment or with another antibiotic regimen for the treatment of MRSA-infected non surgical wounds. We included all relevant RCTs in the analysis, irrespective of language, publication status, publication year, or sample size. Two review authors independently identified the trials, and extracted data from the trial reports. We

    Surgical management of gunshot wounds of the head has remained a controversial issue in the care of civilian patients. In an attempt to determine who might benefit from aggressive surgical intervention, we examined 89 patients over a 3-year period who had suffered cranial gunshot wounds and had at least one computed tomographic scan of the head after admission. Patients were divided into those receiving early (less than 24 hours) surgical intervention (ES, n = 27), late (greater than 24 hours) surgical intervention (LS, n = 6) or no surgical intervention (NS, n = 56). Overall mortality was 63%. Ten of 27 patients (37%) in the ES group died compared with 46 of 56 patients (82%) in the NS group (p less than 0.0001). Glasgow Coma Scale (GCS) scores in the ES group averaged 7.86 +/- 4.72 and in the NS group 5.59 +/- 4.42 (p less than 0.05). The GCS scores in the LS group (all of whom survived) were significantly higher than those of the other two groups, 12.17 +/- 4.10. The number of patients with GCS scores of 3 or 4 on admission was significantly less in the ES (41%) than in the NS group (66%, p = 0.035) and survival was better with surgery (36%) than without (3%, p = 0.007). Patients with mass lesions (clot, ventricular blood) were more often found in the ES group (17/27) than in the NS group (18/56) (p = 0.008). Patients with bihemispheric injuries fared better with surgery (7 of 14 survivors) than without (2 of 33 survivors, p = 0.0003). Only one infectious complication (brain abscess) was encountered in the LS group. No delayed intracranial complications in survivors in the NS group were seen.(ABSTRACT TRUNCATED AT 250 WORDS)

    Previous studies have shown that surgical castration wounds take between 10 and 61 d to heal. The objectives of this work were to describe healing, inflammation, lying behavior, and serum concentration of substance P after surgical castration in beef calves and to evaluate the effect of a possible intervention, a single injection of flunixin meglumine (1.1 mg/kg IV, a NSAID), on the healing process. Calves (mean±SE: 25±2.0 d of age; 54±1.4 kg BW) were surgically castrated with or without an injection of flunixin immediately before the procedure (n=24/treatment). Healing was measured with a 5-point scale (1=fresh wound, 5=no visible incision or inflammation) as well as weight gain, scrotal size, and scrotal surface temperature, on d 1, 2, 3, 7, 14, 21, 28, 35, 49, and 63 after castration. Serum concentration of substance P was recorded on all d, including d 0, but not d 63. Lying behavior was recorded with loggers from 2 d before to 29 d after castration. Inflammation, as measured by scrotal size, peaked on d 2 and 3 after the procedure (e.g., 51±1.0 mm on d 2 versus 28±1.3 mm before castration) and then declined with time (Pcastration (41±1.2 pg/mL), possibly because the sample was collected after the lidocaine ring block was administered, which was likely painful, and because of separation from the dam and restraint. Values began to drop by d 3 (34±1.2 pg/mL) and leveled out by d 21 (30±1.2 pg/mL; Pcastration caused inflammation in the days that followed, and the wounds required a minimum of 4 wk to heal. Provision of an NSAID had no effect on these outcomes.

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

    2015-01-01

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

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

    Obese women have a high incidence of wound separation after gynecologic surgery. We explored the effect of a prospective care pathway on the incidence of wound complications. Women with a body mass index (BMI) ≥30 kg/m(2) undergoing a gynecologic procedure by a gynecologic oncologist via a vertical abdominal incision were eligible. The surgical protocol required: skin and subcutaneous tissues to be incised using a scalpel or cutting electrocautery, fascial closure using #1 polydioxanone suture, placement of a 7 mm Jackson-Pratt drain below Camper's fascia, closure of Camper's fascia with 3-0 plain catgut suture and skin closure with staples. Wound complication was defined as the presence of either a wound infection or any separation. Demographic and perioperative data were analyzed using contingency tables. Univariable and multivariable regression models were used to identify predictors of wound complications. Patients were compared using a multivariable model to a historical group of obese patients to assess the efficacy of the care pathway. 105 women were enrolled with a median BMI of 38.1. Overall, 39 (37%) had a wound complication. Women with a BMI of 30-39.9 kg/m(2) had a significantly lower risk of wound complication as compared to those with a BMI >40 kg/m(2) (23% vs 59%, pcontrolling for factors associated with wound complications the prospective care pathway was associated with a significantly decreased wound complication rate in women with BMI <40 kg/m(2) (OR 0.40, 95% C.I.: 0.18-0.89). This surgical protocol leads to a decreased rate of wound complications among women with a BMI of 30-39.9 kg/m(2). Copyright © 2014 Elsevier Inc. All rights reserved.

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

    We sought to examine whether vacuum-assisted closure (VAC) is associated with fewer surgical site infections (SSIs) or infections of chronic wounds than other management procedures for surgical wounds. The PubMed and Scopus databases were searched systematically. Randomized controlled trials (RCTs) comparing the development of SSIs or infections of chronic wounds between patients treated with VAC for acute or chronic wounds and those whose wounds were treated without VAC were considered eligible for inclusion in the study. Eight RCTs met the inclusion criteria for the study. Four of the studies included chronic or diabetic lower extremity wounds and four included fractures. In three of four studies reporting on fractures, the wounds were not closed post-operatively, whereas in one study primary closure of the wound was performed. With regard to wounds left open after the stabilization of fractures, patients whose wounds were treated with VAC developed fewer SSIs than those whose wounds were treated without VAC ([367 patients (196 with VAC; 171 without VAC) relative risk [RR], 0.47; 95% CI 0.28-0.81]). On the contrary, no difference in the development of SSIs occurred among patients with chronic or diabetic lower-extremity wounds treated with VAC and those whose wounds were treated without VAC ([638 patients (320 with VAC; 318 without VAC) RR 1.67; 95% CI: 0.71-3.94]). The available evidence suggests that the development of infections in wounds treated with VAC depends on the type of wound being treated.

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

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

Participants were frequently at pains not to blame healthcare personnel or hospitals, often discounting the infection's severity, and attributing it to chance, to 'germs' or to their own failure to buy and apply wound care products. The participants' stoicism was thus partly afforded by their refusal to blame healthcare institutions or personnel. Where anger was described, this was either defused or expressed on behalf of another person. Emotional capital is associated with deflecting the possibility of complaint and sustaining a deferential and grateful position in relation to the healthcare system. © 2014 The Authors.

    Vogt, Katja C; Uhlyarik, M; Schroeder, Torben V

    2007-01-01

    This study was a randomized-controlled trial comparing the standard type of dry dressing, Mepore, with moist wound healing, using a hydrofiber dressing, Aquacel, in primary closed wounds after vascular surgery. The endpoints were patient comfort, cost-effectiveness, infections, wound complications......, and length of hospital stay. One hundred and sixty patients were randomized to receive either Mepore or Aquacel dressing. There was no significant difference in patient comfort between the two groups, but a higher cost in the Aquacel group despite significantly fewer changes of dressings in these patients...

    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.

    The global push to combat the problem of antimicrobial resistance has led to the development of antimicrobial stewardship programs (ASPs), which were recently mandated by The Joint Commission and the Centers for Medicare and Medicaid Services. However, the use of topical antibiotics in the open surgical wound is often not monitored by these programs nor is it subject to any evidence-based standardization of care. Survey results indicate that the practice of using topical antibiotics intraoperatively, in both irrigation fluids and powders, is widespread. Given the risks inherent in their use and the lack of evidence supporting it, the practice should be monitored as a core part of ASPs, and alternative agents, such as antiseptics, should be considered.

    Surgical site infections (SSIs) occur at an average rate of 21.1 per cent after Whipple procedures per NSQIP data. In the setting of adherence to standard National Surgery Quality Improvement Program (NSQIP) Hepatopancreatobiliary recommendations including wound protector use and glove change before closing, this study seeks to evaluate the efficacy of using negative pressure wound treatment (NPWT) over closed incision sites after a Whipple procedure to prevent SSI formation. We retrospectively examined consecutive patients from January 2014 to July 2016 who met criteria of completing Whipple procedures with full primary incision closure performed by a single surgeon at a single institution. Sixty-one patients were included in the study between two cohorts: traditional dressing (TD) (n = 36) and NPWT dressing (n = 25). There was a statistically significant difference (P = 0.01) in SSI formation between the TD cohort (n = 15, SSI rate = 0.41) and the NPWT cohort (n = 3, SSI rate = 0.12). The adjusted odds ratio (OR) of SSI formation was significant for NPWT use [OR = 0.15, P = 0.036] and for hospital length of stay [OR = 1.21, P = 0.024]. Operative length, operative blood loss, units of perioperative blood transfusion, intraoperative gastrojejunal tube placement, preoperative stent placement, and postoperative antibiotic duration did not significantly impact SSI formation (P > 0.05).

    Full Text Available Background & Objectives: Wounds healing especially as to surgical wounds is considered clinical problem. Kombucha is used as a food and adminstarted for wound healing. The aim of this study was to assess histopathological and histomorphometrical effect of Kombucha on surgical wound healing process in stomach of rat. Methods: Thirty adult male Wistar rats with 10-week-old and weighted between 200-250 g were randomly divided into two groups (Control and Experimenral. After anesthesia, rats’ stomach was removed and a gastrotomy incision with the length of 1 cm was made in greater curvature, thereafter, sutured in 2 layers. Experimental group received Kombucha extract (1 ml/100gbw and control group received normal saline (1 ml/100gbw daily for 14 days through the gavage. In 3, 7 and 14 days after operation, five rats of each group were euthanized and stomach tissue specimens were collected for histopatholocical study by H&E and Masson's trichrome staining. Histopathological and histomorphometrical studies of wound healing among the groups were carried out considering more effective agents on wound healing including proliferation of fibroblasts, angiogenesis, re-epithelialization and collagen organization in healing tissue. Results: The numbers of fibroblasts, capillary buds and organized collagen content in healing site of experimental group were significantly more than control group (p<0.05. The size of epithelial gap in experimental group was significantly lesser than control group (p<0.05. Conclusion: Based on the results, Kombucha extract possesses beneficial effects on healing of stomach surgical wounds in rats.

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

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

  5. Modelling the cost implications of using carboxymethylcellulose dressing compared with gauze in the management of surgical wounds healing by secondary intention in the US and UK.

    To estimate the costs of using carboxymethyl cellulose dressing (CMCD; Aquacel* Hydrofiber) compared to gauze in managing surgical wounds healing by secondary intention in the US and UK. This was a modelling study performed from the perspective of payers (i.e. the hospital and community sector in the US and the National Health Service (NHS) in the UK). Clinical outcomes attributable to managing surgical wounds healing by secondary intention with gauze were obtained from the published literature in the English language. There were no published studies on wounds healing by secondary intention with CMCD. Hence, the analysis conservatively assumed that wound healing rates associated with gauze would be the same for CMCD. These data were combined with resource utilisation estimates derived from a panel of clinicians enabling us to perform decision modelling. The models were used to determine the expected direct healthcare costs eight weeks after the surgical wounds were dressed by CMCD or gauze and left to heal by secondary intention in the US and UK. All wounds are expected to heal within eight weeks, irrespective of dressing. Managing abscesses and other surgical wounds with CMCD instead of gauze in the US is expected to reduce costs by 4% in both wound types (i.e. $247 and $507 respectively) per patient over eight weeks. In the UK, managing abscesses and other surgical wounds with CMCD instead of gauze is expected to reduce costs by 30% (574 pounds) and 12% (581 pounds) respectively per patient over eight weeks. The lower cost of managing CMCD-treated patients is due to decreased nursing costs associated with a lower frequency of CMCD changes compared to gauze dressing changes. Dressing surgical wounds healing by secondary intention with CMCD instead of gauze is expected to lead to a reduction in healthcare costs in both the US and UK. Hence, the purchase price of a dressing is not indicative of the cost effectiveness of a given method of surgical wound care.

    The resistance demonstrated by many microorganisms towards conventional antibiotics has stimulated the interest in alternative antimicrobial agents and in novel approaches for prevention of infections. Silver, a natural braod-spectrum antimicrobial agent known since antiquity, has been widely employed in biomedical field due to its recognized antibacterial, antifungal and antiviral properties. In this work, antibacterial silver coatings were deposited on absorbable surgical sutures through the in situ photo-chemical deposition of silver clusters. Scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDX) and thermo-gravimetric analysis (TGA) were performed in order to investigate the presence and distribution of the silver clusters on the substrate. The amounts of silver deposited and released by the silver treated sutures were calculated through Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS), and the results were related to the biodegradation of the material. The microbiological properties and the potential cytotoxicity of the silver-treated sutures were investigated in relation with hydrolysis experiments, in order to determine the effect of the degradation on antibacterial properties and biocompatibility. - Highlights: • The in situ photo-deposition of silver nano-coatings was used to develop silver treated PGLA sutures. • The silver particles deposited had good distribution and strong adhesion to the substrate. • The silver treated sutures demonstrated good biocompatibility and antibacterial capability. • The presence of silver promoted cell migration and proliferation in the wound area.

    Full Text Available Surgical site infections remain one of the most frequent complications following abdominal surgery and cause substantial costs, morbidity and mortality.To assess the effectiveness of wound edge protectors in open abdominal surgery in reducing surgical site infections.A systematic literature search was conducted according to a prespecified review protocol in a variety of data-bases combined with hand-searches for randomized controlled trials on wound edge protectors in patients undergoing laparotomy. A qualitative and quantitative analysis of included trials was conducted.We identified 16 randomized controlled trials including 3695 patients investigating wound edge protectors published between 1972 and 2014. Critical appraisal uncovered a number of methodological flaws, predominantly in the older trials. Wound edge protectors significantly reduced the rate of surgical site infections (risk ratio 0.65; 95%CI, 0.51-0.83; p = 0.0007; I2 = 52%. The results were robust in a number of sensitivity analyses. A similar effect size was found in the subgroup of patients undergoing colorectal surgery (risk ratio 0.65; 95%CI, 0.44-0.97; p = 0.04; I2 = 56%. Of the two common types of wound protectors double ring devices were found to exhibit a greater protective effect (risk ratio 0.29; 95%CI, 0.15-0.55 than single-ring devices (risk ratio 0.71; 95%CI, 0.54-0.92, but this might largely be due to the lower quality of available data for double-ring devices. Exploratory subgroup analyses for the degree of contamination showed a larger protective effect in contaminated cases (0.44; 95%CI, 0.28-0.67; p = 0.0002, I2 = 23% than in clean-contaminated surgeries (0.72, 95%CI, 0.57-0.91; p = 0.005; I2 = 46% and a strong effect on the reduction of superficial surgical site infections (risk ratio 0.45; 95%CI, 0.24-0.82; p = 0.001; I2 = 72%.Wound edge protectors significantly reduce the rate of surgical site infections in open abdominal surgery.

    Surgical wound classification (SWC) is used for risk stratification of surgical site infection (SSI) and serves as the basis for measuring quality of care. The objective was to examine the accuracy and reliability of SWC. This study was purposed to evaluate the discrepancies in SWC as assessed by three groups: surgeons, an infection control nurse, and histopathologic evaluation. The secondary aim was to compare the risk-stratified SSI rates using the different SWC methods for 30 d postoperatively. An analysis was performed of the appendectomies from January 2013 to June 2014 in the Cantonal Hospital of Schaffhausen. SWC was assigned by the operating surgeon at the end of the procedure and retrospectively reviewed by a Swissnoso-trained infection control nurse after reading the operative and pathology report. The level of agreement among the three different SWC assessment groups was determined using kappa statistic. SSI rates were analyzed using a chi-square test. In 246 evaluated cases, the kappa scores for interrater reliability among the SWC assessments across the three groups ranged from 0.05 to 0.2 signifying slight agreement between the groups. SSIs were more frequently associated with trained infection control nurse-assigned SWC than with surgeons based SWC. Our study demonstrated a considerable discordance in the SWC assessments performed by the three groups. Unfortunately, the currently practiced SWC system suffers from ambiguity in definition and/or implementation of these definitions is not clearly stated. This lack of reliability is problematic and may lead to inappropriate comparisons within and between hospitals and surgeons. Copyright © 2017 The Author(s). Published by Elsevier Inc.

    2017-04-01

    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.

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

    2011-03-01

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

    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.)

    Soft tissue sarcomas occur most commonly in the lower and upper extremities. The standard treatment is limb salvage surgery combined with radiotherapy. Postoperative radiotherapy is associated with wound complications. This systematic review aims to summarise the available evidence and review the literature of the last 10 years regarding postoperative wound complications in patients who had limb salvage surgical excision followed by direct closure vs flap coverage together with postoperative radiotherapy and to define the optimal timeframe for adjuvant radiotherapy after soft tissue sarcomas resection and flap reconstruction. A literature search was performed using PubMed. The following keywords were searched: limb salvage, limb-sparing, flaps, radiation therapy, radiation, irradiation, adjuvant radiotherapy, postoperative radiotherapy, radiation effects, wound healing, surgical wound infection, surgical wound dehiscence, wound healing, soft tissue sarcoma and neoplasms. In total, 1045 papers were retrieved. Thirty-seven articles were finally selected after screening of abstracts and applying dates and language filters and inclusion and exclusion criteria. Plastic surgery provides a vast number of reconstructive flap procedures that are directly linked to decreasing wound complications, especially with the expectant postoperative radiotherapy. This adjuvant radiotherapy is better administered in the first 3-6 weeks after reconstruction to allow timely wound healing and avoid local recurrence. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    The risk of a wound dehiscence requiring chest wall port explant in patients treated with bevacizumab is inversely proportional to the interval between bevacizumab administration and port placement. There is significantly higher risk of wound dehiscence when the interval between bevacizumab administration and chest wall port placement is less than 14 days.

    To determine the optimum concentration of a gel obtained from unripe banana (Musa sapientum) peel for wound treatment in rats. A randomized triple blind study was conducted with 40 Wistar rats, which were divided into 4 groups: CG, control group; G2%, 2% gel concentration group; G4%, 4% gel concentration group; and G10%, 10 % gel concentration group. The banana peel gel was applied daily, for 7 days, to a 4-cm(2) wound created on the back of each animal of all groups. After this period, the wounds were biopsied. Statistical analysis was carried out using the Kruskal-Wallis test complemented by the Student-Newman-Keuls test. Macroscopic examination revealed that partial epithelialization occurred in all groups. Wound contraction was also observed in all groups and ranged from 1.38 to 1.57 mm in the study groups, and from 1.03 to 1.10 mm in the control group, with significant differences (p banana peel (G4%) resulted in better epithelialization of wounds healed by secondary intention compared with other gel concentrations.

    A clinical audit was performed to evaluate whether Acapsil micropore particle technology (MPPT) powder could improve the management of acute wounds to heal by secondary intention. Wounds, which could be characterised as sloughy, wet and probably infected, normally managed by debridement followed by negative pressure wound therapy (NPWT), were included in the evaluation. The MPPT powder was applied topically to the wound surface either once daily or on alternate days, with each wound receiving a total of two to five applications. Most patients had NPWT after the MPPT powder treatment had finished to assist healing. The study included nine patients with dehisced surgical wounds and one with a category IV pressure ulcer (PU). The wounds were generally covered in slough, exudate and showing signs of local infection. The topical MPPT powder rapidly desloughed the wounds, controlled exudate levels, promoted granulation and was well tolerated. All wounds proceeded towards closure. Comparison of the present data with MPPT powder to standard treatment suggests that the speed of healing using MPPT was improved. Further examination is required to determine if this reduces dressing changes, nursing time, and financial cost.

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

    Superior canal dehiscence syndrome (SCDS) is an increasingly recognized cause of hearing loss and vestibular symptoms, but the etiology of this condition remains unknown. To describe 7 cases of SCDS across 3 families. This retrospective case series included 7 patients from 3 different families treated at a neurotology clinic at a tertiary academic medical center from 2010 to 2014. Patients were referred by other otolaryngologists or were self-referred. Each patient demonstrated unilateral or bilateral SCDS or near dehiscence. Clinical evaluation involved body mass index calculation, audiometry, cervical vestibular evoked myogenic potential testing, electrocochleography, and multiplanar computed tomographic (CT) scan of the temporal bones. Zygosity testing was performed on twin siblings. The diagnosis of SCDS was made if bone was absent over the superior semicircular canal on 2 consecutive CT images, in addition to 1 physiologic sign consistent with labyrinthine dehiscence. Near dehiscence was defined as absent bone on only 1 CT image but with symptoms and at least 1 physiologic sign of labyrinthine dehiscence. A total of 7 patients (5 female and 2 male; age range, 8-49 years) from 3 families underwent evaluation. Family A consisted of 3 adult first-degree relatives, of whom 2 were diagnosed with SCDS and 1 with near dehiscence. Family B included a mother and her child, both of whom were diagnosed with unilateral SCDS. Family C consisted of adult monozygotic twins, each of whom was diagnosed with unilateral SCDS. For all cases, dehiscence was located at the arcuate eminence. Obesity alone did not explain the occurrence of SCDS because 5 of the 7 cases had a body mass index (calculated as weight in kilograms divided by height in meters squared) less than 30.0. Superior canal dehiscence syndrome is a rare, often unrecognized condition. This report of 3 multiplex families with SCDS provides evidence in support of a potential genetic contribution to the etiology

    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.

    To identify risk factors for dehiscence in stapled functional end-to-end anastomoses (SFEEA) in dogs. Retrospective case series. Dogs (n = 53) requiring an enterectomy. Medical records from a single institution for all dogs undergoing an enterectomy (2001-2012) were reviewed. Surgeries were included when gastrointestinal (GIA) and thoracoabdominal (TA) stapling equipment was used to create a functional end-to-end anastomosis between segments of small intestine or small and large intestine in dogs. Information regarding preoperative, surgical, and postoperative factors was recorded. Anastomotic dehiscence was noted in 6 of 53 cases (11%), with a mortality rate of 83%. The only preoperative factor significantly associated with dehiscence was the presence of inflammatory bowel disease (IBD). Surgical factors significantly associated with dehiscence included the presence, duration, and number of intraoperative hypotensive periods, and location of anastomosis, with greater odds of dehiscence in anastomoses involving the large intestine. IBD, location of anastomosis, and intraoperative hypotension are risk factors for intestinal anastomotic dehiscence after SFEEA in dogs. Previously suggested risk factors (low serum albumin concentration, preoperative septic peritonitis, and intestinal foreign body) were not confirmed in this study. © Copyright 2015 by The American College of Veterinary Surgeons.

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

    The rabbit is one of the most widely used models for studying bone remodeling or dental implant osseointegration but very few data are available about the rabbit's mandible. The aim of this work was to describe the anatomy of the rabbit mandible and to estimate the available bone volume for experimental studies. First, with a dissection, the morphology of the mandible was described and the mental foramen, the position of the main salivary glands and muscular insertions were located. Then, by X-ray imaging, the position of the inferior alveolar canal, the dental root courses and volume and bone density were described. Finally, with frontal sections of the mandible body, the rabbit's dental and alveolar bone histological structure were assessed. Thus, the relevance of the rabbit mandible as an experimental model for wound healing or surgical therapies was discussed. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

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

    Although vacuum-assisted closure (VAC) is a well-established technique in other surgical specialties, its use has not been established in the foot and ankle. The aims of this study were to determine if vacuum-assisted closure therapy (VAC) helps assist closure in diabetic foot ulcers and wounds secondary to peripheral vascular disease, if it helps debride wounds, and if it prevents the need for further surgery. We retrospectively reviewed 15 patients (18 wounds or ulcers) with primary diagnoses of diabetes (10 patients), chronic osteomyelitis (two patients), peripheral vascular disease (two patients), and spina bifida (one patient). Eleven of the 15 patients had serious comorbidities, such as peripheral neuropathy, renal failure, and wound dehiscence. All wounds were surgically debrided before VAC therapy was applied according to the manufacturer's instructions. The main outcome measures were time to satisfactory wound closure, changes in the wound surface area, and the need for further surgery. Satisfactory healing was achieved in 13 of the 18 wounds or ulcers at an average of 2.5 months. VAC therapy failed in five patients (five class III ulcers), three of whom required below-knee amputations. Wound or ulcer size decreased from an average of 7.41 cm(2) before treatment to an average of 1.58 cm(2) after treatment. VAC therapy is a useful adjunct to the standard treatment of chronic wound or ulcers in patients with diabetes or peripheral vascular disease. Its use in foot and ankle surgery leads to a quicker wound closure and, in most patients, avoids the need for further surgery.

    2015-10-01

    The treatment of deep pressure ulcer with a wide wound edge undermining (pocket) is challenging, especially when conservative treatments are ineffective. As most patients with a pressure ulcer suffer from systemic comorbidities, invasive surgery cannot be performed on all patients, and less invasive treatment is required. Less invasive surgical intervention to a deep pressure ulcer, parallel pocket incision (PPI), was performed on 10 patients with intractable pressure ulcers with a pocket formation. In PPI procedures, two parallel skin incisions were made to open up the deepest fold of the pocket and to preserve the skin overlying the pocket lesion; through the created incisions, the necrotic tissues around the deepest fold of the undermining could be easily removed, which facilitated spontaneous wound healing. Postoperative results and complications were evaluated. All PPI procedures were safely performed under local infiltration anesthesia without major postoperative complication; minor bleeding was seen intraoperatively in three patients, which could be easily controlled with electric cautery coagulation. Nine of 10 ulcers were cured after PPI, and one could not be followed up due to the patient's death non-related to the pressure ulcer. For the nine cured patients, the average time for cure was 14.9 weeks, and no recurrence was observed at postoperative 6 months. PPI is a simple, technically easy, and less invasive surgical intervention to an intractable pressure ulcer with a pocket, which can be safely performed under local infiltration anesthesia even on a patient with severe systemic comorbidities.

    We prospectively analyzed our experience with operative videothoracoscopy (OVT) performed in a field military hospital in cases of penetrating firearms wounds of the thorax (PFAWT) sustained in Chechnya. From February to April 1996, we treated 206 wounded patients, of whom 37 (18.0%) had sustained chest injuries. PFAWT were present in 23 soldiers, accounting for 62.2% of all chest injuries. Twelve injuries were confined to the thorax, eight patients had associated injuries, and three soldiers had thoracoabdominal injuries. Nineteen patients had pleural drainage performed during medical evacuation. The thoracic injuries were right-sided (17), involved bullets or shell splinters (23); were through and through (16), represented solitary wounds (19), and were associated with internal organ injuries (21). Fifteen patients had indications for OVT when they were delivered from the battle-field 1.5 to 22 hours after injury. All patients manifested signs of hemorrhagic shock and hemodynamic instability. Indications for OVT were ongoing intrapleural bleeding (6), clotted hemothorax (6), or marked air leakage (3) preventing lung inflation with the OP-02 apparatus (field modification). OVT revealed 12 lung wounds, nine of which were multiple wounds, pleural bleeding in 6 patients, clotted hemothorax in 11 patients, and foreign bodies in 5 patients. Two patients underwent thoracotomy, one for suspicion of heart injury and the second because we could not adequately visualize and control bleeding revealed at OVT to be from the intercostal artery in the left costovertebral angle. Eight of 23 patients had no indication for operative videothoracoscopy and were managed with continued pleural aspiration and drug therapy. Wedge resection of the lung using an Endo-GIA-30 stapler was necessary in two patients because of parenchymal destruction and bleeding. Evacuation of clotted blood by fragmentation and aspiration was satisfactory in all cases. Satisfactory manual suturing of selected

    The aim of the present study was to evaluate and compare the wound-healing process following osteotomies performed with either conventional rotary burs or piezoelectric surgery in a rabbit model. Two types of osteotomy window defects of the nasal cavities were prepared on the nasal bone of 16 adult New Zealand white rabbits with either a conventional rotary bur or piezo surgery. The defects were covered with a resorbable membrane. Four animals were killed at 1, 2, 3, and 5 weeks after the surgical procedure, respectively. Histological and morphometric evaluations were performed to assess the volumetric density of various tissue components: the blood clot, vascularized structures, provisional matrix, osteoid, mineralized bone, bone debris, residual tissue, and old bone. Significantly more bone debris was found at 1 week in the conventionally-prepared defects compared to the piezo surgically-prepared defects. At 2 and 3 weeks, a newly-formed hard tissue bridge, mainly composed of woven bone, was seen; however, no statistically-significant differences were observed. At 5 weeks, the defects were completely filled with newly-formed bone. The defects prepared by piezo surgery showed a significantly decreased proportion of bone debris at 1 week, compared to conventional rotary bur defect. © 2014 Wiley Publishing Asia Pty Ltd.

    To determine the frequency of dehiscence of hand-sutured and stapled intestinal anastomoses in the dog and compare the surgery duration for the methods of anastomosis. Historical cohort study. Two hundred fourteen client-owned dogs undergoing hand-sutured (n = 142) or stapled (n = 72) intestinal anastomoses. Medical records from 5 referral institutions were searched for dogs undergoing intestinal resection and anastomosis between March 2006 and February 2014. Demographic data, presence of septic peritonitis before surgery, surgical technique (hand-sutured or stapled), surgery duration, surgeon (resident versus faculty member), indication for surgical intervention, anatomic location of resection and anastomosis, and if dehiscence was noted postoperatively were retrieved. Estimated frequencies were summarized and presented as proportions and 95% confidence intervals (CI) and continuous outcomes as mean (95% CI). Comparisons were made across methods of anastomosis. Overall, 29/205 dogs (0.14, 95% CI 0.10-00.19) had dehiscence, including 21/134 dogs (0.16, 0.11-0.23) undergoing hand-sutured anastomosis and 8/71 dogs (0.11, 0.06-0.21) undergoing stapled anastomosis. There was no significant difference in the frequency of dehiscence across anastomosis methods (χ(2), P = .389). The mean (95% CI) surgery duration of 140 minutes (132-147) for hand- sutured anastomoses and 108 minutes (99-119) for stapled anastomoses was significantly different (t-test, P < .001). No significant difference in frequency of dehiscence was noted between hand- sutured and stapled anastomoses in dogs but surgery duration is significantly reduced by the use of staples for intestinal closure. © Copyright 2015 by The American College of Veterinary Surgeons.

  4. Buried chip skin grafting in neuropathic diabetic foot ulcers following vacuum-assisted wound bed preparation: enhancing a classic surgical tool with novel technologies.

    In patients with diabetes mellitus, complications such as polyneuropathy and peripheral angiopathy inevitably lead to diabetic foot complications including foot ulcers, gangrene, and osteoarthropathy. These conditions necessitate minor or major amputation as part of treatment. In patients with Charcot's arthropathy and predominant neuropathy, recurrent foot ulcers are common in areas of high pressure. Such high pressure is caused by the degrading of the architecture of the foot and inadequate footwear. These patients are a clinical challenge. A select group of such patients may benefit from free surgical tissue transfer, though free or local flap surgery is often difficult or even impossible owing to an impaired arterial circulation. In such wounds, surgical debridement followed by skin grafts often fail due to bacterial burden in the wounds. To circumvent these problems, the authors developed a therapeutic approach using buried chip skin grafting to close granulation wound beds in diabetic feet. Locally applied vacuum therapy (VAC) for wound bed preparation of chronic, nonresponsive foot ulcers and subsequent grafting using the burying technique with a minute fraction of skin was used. Firm closure was achieved. The closed wound was resistant to mechanical irritation.

    Full Text Available Introduction: Vaginal cuff dehiscence is a rare complication following hysterectomy. The condition coexisting with intraabdominal organ evisceration occurs even rarer. Nevertheless this should not be neglected owing to high morbidity and mortality. Case presentation: The reported case is a 48-year-old widow presenting with vaginal cuff dehiscence and small bowel evisceration after undergoing a total abdominal hysterectomy (TAH in the past 14 months due to myoma uteri. She denied having a history of sexual intercourse after the operation. The exposed bowel, 60 cm in length, appeared viable and no peritoneal sign was observed. There was a vaginal cuff defect approximately 3 cm in length. An exploratory laparotomy was then carried out. Eviscerated bowel was reduced back in the abdominal cavity and the vaginal cuff defect was repaired. No complications such as recurrent dehiscence were observed during one year follow-up. Conclusion: To minimize the incidence of vaginal cuff dehiscence after hysterectomy, surgical techniques should be of concern. Patient instructions, including delaying sexual intercourse and avoiding all possible causes of increased intra-abdominal pressure should be provided postoperatively.

    The objective of this study is to determine the role of ne needle aspiration microbiology (FNAM) in detecting the causative organisms of postoperative surgical site infections (SSIs) in comparison with the standard technique of surface swabbing. Ma- terials and Methods. In this study, 150 patients with SSIs following elective and emergency operations were included. In all patients, FNAM was performed along with conventional surface swabbing to identify the causative microorganism. Sensitivity of surface swab and FNAM was calculated as the number of samples collected from the diagnosed case of SSI. A total of 115 positive cultures were obtained from the 150 patients with SSIs; surface swab was positive in 110 cases and FNAM was positive in 94 cases. The mean number of organisms isolated by surface swab, and FNAM was 0.95 and 0.8, respectively. The sensitivity of surface swab was 94.3% in elective cases and 96.25% in emergency cases. The sensitivity of FNAM was 82.8% in elective cases and 82.5% in emergency cases. The sensitivity and negative predictive value of FNAM and surface swab did not signi cantly differ in clean elective cases. The overall sensitivity of surface swab and FNAM was 95.65% and 81.7%, respectively. Comparing the antibiotic suscep- tibility pattern, no difference was observed when the same organ- ism was isolated by both methods, indicating that FNAM does not offer bene t over the conventional wound surface swab in detecting microorganisms in SSI in both elective and emergency surgeries. In certain cases with unexplained wound infections, FNAM can be used as an investigation to identify speci c pathogens not detected by conventional surface swab.

    Surgical site infection (SSI) remains to be one of the most frequent infectious complications following abdominal surgery. Prophylactic intra-operative wound irrigation (IOWI) before skin closure has been proposed to reduce bacterial wound contamination and the risk of SSI. However, current recommendations on its use are conflicting especially concerning antibiotic and antiseptic solutions because of their potential tissue toxicity and enhancement of bacterial drug resistances. To analyze the existing evidence for the effect of IOWI with topical antibiotics, povidone-iodine (PVP-I) solutions or saline on the incidence of SSI following open abdominal surgery, a systematic review and meta-analysis of randomized controlled trials (RCTs) was carried out according to the recommendations of the Cochrane Collaboration. Forty-one RCTs reporting primary data of over 9000 patients were analyzed. Meta-analysis on the effect of IOWI with any solution compared to no irrigation revealed a significant benefit in the reduction of SSI rates (OR = 0.54, 95 % confidence Interval (CI) [0.42; 0.69], p < 0.0001). Subgroup analyses showed that this effect was strongest in colorectal surgery and that IOWI with antibiotic solutions had a stronger effect than irrigation with PVP-I or saline. However, all of the included trials were at considerable risk of bias according to the quality assessment. These results suggest that IOWI before skin closure represents a pragmatic and economical approach to reduce postoperative SSI after abdominal surgery and that antibiotic solutions seem to be more effective than PVP-I solutions or simple saline, and it might be worth to re-evaluate their use for specific indications.

    Wound dehiscence after chemo-port placement is a rare but potentially significant complication. We hypothesize that by using a simple running skin closure technique during chemo-port placement the rate of wound dehiscence and overall wound complications can be significantly decreased. IRB approval was obtained and patients port from June 2012 to April 2016 were analyzed. Data collected on patients included patient demographics, skin closure type, and wound complications within 30days. Chi-square was performed to examine the univariate association with skin closure technique and wound dehiscence. Logistic regression was performed to examine the multivariable association between skin closure type and wound dehiscence and to compute odds ratios. There were 259 ports placed in this cohort: 125 used simple running skin closure technique, and 134 used the subcuticular skin closure. Patients were found to not have any difference in rate of dehiscence or overall wound complications based on gender, age, location of port, or use of steroids or chemotherapy within 1week of port placement. When compared, only 1 case (0.80%) in the simple running group vs 10 cases (7.46%) in the subcuticular group experienced a wound dehiscence [unadjusted OR=14.07 (1.69, 116.99) p=0.0144]. When comparing overall wound complications the simple running group had 3 (2.4%) versus 12 (8.96%) in the subcuticular group [unadjusted OR=4.78 (1.27, 17.94) p=0.0203]. When adjusting for port-number both dehiscence and overall wound complications remained statistically significant. We conclude that the simple running skin closure for chemo-port placement in children has superior outcomes in regards to prevention of dehiscence and overall wound related complications when compared to the subcuticular technique.

    Full Text Available The aim of present study to analyze the occurrence and in-vitro antimicrobial susceptibility of bacterial pathogens isolated from surgical wound infections. Specimens from a total of 129 patients undergoing either emergency or elective surgery were collected from infected sites or stitch lines and inoculated onto appropriate media. The bacterial cultures were identified utilizing standard microbiological and biochemical methods. Isolates were tested for susceptibility to antimicrobials using the Kirby Bauer disk diffusion method. Statistical analysis was performed using the chi-square test. Of 129 patients investigated (62 emergency and 67 elective surgery cases, bacterial isolates were isolated with almost equal frequency both from emergency and elective surgery cases. Of 108 (83.72% culture positive samples, 62 (57.41% were Gram negative, 39 (36.11% Gram positive, and 7 (6.48% showed multiple organisms.

    The purpose of this study was to examine the recurrence rate of wound rupture in primary pilonidal sinus disease (PSD) after median closure. A total of 583 patients from the German military cohort were interviewed. We compared the choice of surgical therapy, wound dehiscence (if present) and long-term recurrence-free survival for patients with primary open treatment, marsupialization and primary median treatment (closed vs. secondary open, respectively). Actuarial recurrence rate was determined using the Kaplan-Meier calculation with a follow-up of up to 20 years after primary PSD surgery. Patients with excision followed by primary open wound treatment showed a significantly lower 5- than 10-year recurrence rate (8.3 vs. 11.2%) compared to the patients with primary midline closure (17.4 vs. 20.5%, p = 0.03). The 20-year recurrence rate was 28% in primary open wound treatment versus 44% in primary midline closure without wound rupture. In contrast to these findings, long-term recurrence rates following secondary open wound treatment (12.2% at 5 years vs. 17.1% at 10 years) tended to be higher (although not significantly, p = 0.57) compared to primary open treatment (8.3% at 5 years vs. 11.2% at 10 years). There was no statistical difference in long-term recurrence rates between secondary open and primary midline closure (p = 0.7). Hence, despite only a short wound closure time experienced before wound rupture, the patient does not fully benefit from an open wound treatment in terms of recurrence rate. The postoperative pilonidal sinus wound rupture of primary midline closures did not significantly increase the 5- and 10-year long-term recurrence rates compared to uneventfully healing primary midline closures. © 2015 S.

    To determine the influence of preoperative septic peritonitis (PSP) and stapled versus hand-sewn anastomoses on the dehiscence of intestinal resection and anastomosis (IRA). We hypothesized that the incidence of IRA dehiscence would be greater (1) when performed with PSP and (2) for hand-sewn anastomoses. Retrospective. Client-owned dogs at Michigan State University Veterinary Teaching Hospital. Records of dogs surviving 72 hours after IRAs between 2003 and 2013 were reviewed for age, gender, neuter status, weight, presence of PSP, preoperative albumin, IRA indication and location, anastomotic technique, suture type, postoperative dehiscence and timing, duration of hospitalization, last follow-up, and other complications. Univariate logistic regression and chi-square analysis were used to screen prognostic factors; factors with P dogs fulfilled the inclusion criteria. Dehiscence was diagnosed in 11.4% cases, 6.6% without PSP, and 21.1% with PSP (P = .01). Indication for IRA did not influence the risk of dehiscence. No association was detected between anastomotic technique and IRA dehiscence in dogs without PSP (stapled 4.2%, hand-sewn 8.1%); however, stapled anastomoses were less likely to dehisce in dogs with PSP (stapled 9.7%, hand-sewn 28.9%). Risk factors for dehiscence included PSP (P = .005) and hand-sewn technique (P = .02). Our results confirmed that PSP is a risk factor for dehiscence of IRA and suggest that patients with PSP may be a unique surgical population, in which stapling may be preferred over hand-sewn anastomoses after enterectomies. © 2017 The American College of Veterinary Surgeons.

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

    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

    To determine if there is gender or laterality predilection in patients with semicircular canal dehiscence syndrome. A multi-institutional chart review was performed to identify patients diagnosed with semicircular canal dehiscence between 2000 and 2015. A systematic literature search was conducted using PubMed to further identify patients with semicircular canal dehiscence. Age, gender and laterality data were collected. Statistical analysis was performed to evaluate for gender or laterality preponderance. A total of 682 patients with semicircular canal dehiscence were identified by literature and chart review. Mean age of diagnosis was 49.75 years (standard deviation = 15.33). Semicircular canal dehiscence was associated with a statistically significant female predominance (chi-square = 7.185, p = 0.007); the female-to-male ratio was 1.2 to 1. Left-sided semicircular canal dehiscence was most common, followed by right-sided then bilateral (chi-square = 23.457, p < 0.001). Semicircular canal dehiscence syndrome is most commonly left-sided and exhibits a female predominance. This may be secondary to morphological cerebral hemisphere asymmetries in both sexes and a predilection of women to seek more medical care than men.

    Surgical site infections (SSIs) are one of the most common hospital-acquired infections. To reduce SSIs, prophylactic intra-operative wound irrigation (pIOWI) has been advocated, although the results to date are equivocal. To develop recommendations for the new World Health Organization (WHO) SSI prevention guidelines, a systematic literature review and a meta-analysis were conducted on the effectiveness of pIOWI using different agents as a means of reducing SSI. The PUBMED, Embase, CENTRAL, CINAHL, and WHO databases were searched. Randomized controlled trials (RCTs) comparing either pIOWI with no pIOWI or with pIOWI using different solutions and techniques were retrieved with SSI as the primary outcome. Meta-analyses were performed, and odds ratios (OR) and the mean difference with 95% confidence intervals (CI) were extracted and pooled with a random effects model. Twenty-one studies were suitable for analysis, and a distinction was made between intra-peritoneal, mediastinal, and incisional wound irrigation. A low quality of evidence demonstrated a statistically significant benefit for incisional wound irrigation with an aqueous povidone-iodine (PVP-I) solution in clean and clean contaminated wounds (OR 0.31; 95% CI 0.13-0.73; p = 0.007); 50 fewer SSIs per 1,000 procedures (from 19 fewer to 64 fewer)). Antibiotic irrigation had no significant effect in reducing SSIs (OR 1.16; 95% CI 0.64-2.12; p = 0.63). Low-quality evidence suggests considering the use of prophylactic incisional wound irrigation to prevent SSI with an aqueous povidone-iodine solution. Antibiotic irrigation does not show a benefit and therefore is discouraged.

    Abstract Background: This meta-analysis aims to evaluate the efficacy and safety of hip arthroscopy versus open surgical dislocation for treating femoroacetabular impingement (FAI) through published clinical trials. Methods: We conducted a comprehensive literature search using PUBMED, EMBASE, and the Cochrane Central Register of Controlled Trials databases for relevant studies on hip arthroscopy and open surgical dislocation as treatment options for FAI. Results: Compared with open surgical dislocation, hip arthroscopy resulted in significantly higher Nonarthritic Hip Scores (NAHS) at 3- and 12-month follow-ups, a significant improvement in NAHS from preoperation to 3 months postoperation, and a significantly lower reoperation rate. Open surgical dislocation resulted in a significantly improved alpha angle by the Dunn view in patients with cam osteoplasty from preoperation to postoperation, compared with hip arthroscopy. This meta-analysis demonstrated no significant differences in the modified Harris Hip Score, Hip Outcome Score-Activities of Daily Living, or Hip Outcome Score-Sport Specific Subscale at 12 months of follow-up, or in complications (including nerve damage, wound infection, and wound dehiscence). Conclusion: Hip arthroscopy resulted in higher NAHS and lower reoperation rates, but had less improvement in alpha angle in patients with cam osteoplasty, than open surgical dislocation.

    We herein report a case of posterior semicircular canal dehiscence (SCD) syndrome who had been audiologically followed up for eight years. The patient originally had sensorineural hearing loss. The audiogram had gradually transformed to pure conductive hearing loss. The posterior SCD was identified in CT scan. The reported case showed the possibility to distinguish the mechanism at play underlying the typical conductive hearing loss in SCD patients by tracing the transition of the hearing loss pattern. This information is of much help to predict the hearing outcomes if surgical intervention were chosen for the treatment. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

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

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

    To describe the outcomes of vitrectomy for optic disc pit-related maculopathy with central outer retinal dehiscence. This prospective interventional case series included seven patients with optic disc pit with macular schisis and central outer retinal dehiscence who underwent vitrectomy with internal limiting membrane peeling, barrage laser photocoagulation, and gas tamponade and were followed for at least 6 months. The surgical outcomes in terms of restoration of macular anatomy and visual improvement were recorded at each visit by fundus photography and optical coherence tomography. The mean age of the patients was 21.3 ± 8.6 years (range, 10-35 years), and the mean duration of defective vision was 6.7 ± 8.5 months (range, 1-24 months). Preoperatively, the median best-corrected visual acuity (BCVA) was 20/60 (range, 20/40 to 20/120). Full-thickness macular holes were noticed in 4 patients 1 month postoperatively. Gas tamponade was repeated in two patients with large macular holes. By the final follow-up, macular holes had closed and BCVA improved in all patients except one. Final mean central macular thickness was 176.83 ± 55.74 μ, the range being 109 μ to 256 μ. The median postoperative BCVA was 20/30 (range, 20/20 to 20/80). Six of 7 patients (85.7%) had improvement in BCVA postoperatively (mean, +2 lines; range, 1-4 lines). Five patients (71%) achieved a postoperative BCVA of ≥20/30. Best-corrected visual acuity dropped by one line in the patient with persistent macular hole. Vitrectomy with internal limiting membrane peeling can achieve excellent final surgical outcomes in optic pit maculopathy with outer retinal dehiscence despite the potential for macular hole formation.

    We investigated the involvement of ethylene signaling in the development of the reproductive structures in tobacco ( Nicotiana tabacum L.) by studying flowers that were insensitive to ethylene. Ethylene-insensitivity was generated either by expression of the mutant etr1-1 ethylene-receptor allele from Arabidopsis thaliana or by treatment with the ethylene-perception inhibitor 1-methylcyclopropene (MCP). Development of ovaries and ovules was unaffected by ethylene-insensitivity. Anther development was also unaffected, but the final event of dehiscence was delayed and was no longer synchronous with flower opening. We showed that in these anthers degeneration of the stomium cells and dehydration were delayed. In addition, we found that MCP-treatment of detached flowers and isolated, almost mature anthers delayed dehiscence whereas ethylene-treatment accelerated dehiscence. This indicated that ethylene has a direct effect on a process that takes place in the anthers just before dehiscence. Because a similar function has been described for jasmonic acid in Arabidopsis, we suggest that ethylene acts similarly to or perhaps even in concurrence with jasmonic acid as a signaling molecule controlling the processes that lead to anther dehiscence in tobacco.

    Full Text Available Light and electron microscopic studies were undertaken on the flower structure and anther dehiscence of Wolffia arrhiza L. The anthesis is protogynous. The pistil and the stamen were located in dorsal flower cavity and the pistil protrude first. The inner structure of the pistil and the stamen described with special notes on the anther dehiscence line and the septal cells. The pistil is comprised of a concave stigma, a style and a unilocular ovary with one orthotropous ovule. The bitegumic ovule is covered with a secretary substance within the ovary. The stamen has a filament and bilobed monothecous anther. The tannin body in the stomial cells as well as stigma and style may act as a deterrent. Meanwhile, the uneven thickening of the septal walls and the massive central vacuole of the septal cells probably aid the dehiscence of the anther sac.

    Biological disease-modifying antirheumatic drugs (bDMARDs) have become more popular for treating rheumatoid arthritis (RA). Whether or not bDMARDs increase the postoperative risk of surgical site infection (SSI) has remained controversial. We aimed to clarify the effects of bDMARDs on the outcomes of elective orthopedic surgery. We used multivariate logistic regression analysis to analyze risk factors for SSI and delayed wound healing among 227 patients with RA (mean age, 65.0 years; disease duration, 16.9 years) after 332 elective orthopedic surgeries. We also attempted to evaluate the effects of individual medications on infection. Rates of bDMARD and conventional synthetic DMARD (csDMARD) administration were 30.4 and 91.0 %, respectively. Risk factors for SSI were advanced age (odds ratio [OR], 1.11; P = 0.045), prolonged surgery (OR, 1.02; P = 0.03), and preoperative white blood cell count >10,000/μL (OR, 3.66; P = 0.003). Those for delayed wound healing were advanced age (OR, 1.16; P = 0.001), prolonged surgery (OR, 1.02; P = 0.007), preoperative white blood cell count >10,000/μL (OR, 4.56; P = 0.02), and foot surgery (OR, 6.60; P = 0.001). Risk factors for SSI and medications did not significantly differ. No DMARDs were risk factors for any outcome examined. Biological DMARDs were not risk factors for postoperative SSI. Foot surgery was a risk factor for delayed wound healing.

    To compare the effect of application of manuka honey with unique manuka factor (UMF) 5 or 20 with a generic multifloral honey on equine wound healing variables. Two full-thickness skin wounds (2.5 × 2.5 cm) were created on the metatarsus of both hindlimbs of eight Standardbred horses. The wounds on each horse were assigned to 1 of 4 treatments: UMF20 (UMF20) and UMF5 (UMF5) manuka honey; generic multifloral honey (GH); and a saline control. Bandages were changed daily for 12 days, after which treatment was stopped and the bandages were removed. Wound area was measured on day 1, then weekly until day 42. Overall wound healing rate (cm 2 /day) and time to complete healing were recorded. There was no difference in wound area for any of the treatments on any measurement day except for day 21, where the mean wound area for wounds treated with UMF20 was smaller than the mean wound area for the UMF5-treated wounds (P = 0.031). There was no difference in mean (± SE) overall healing rate (cm 2 /day) among the treatment groups. There were differences in mean (± SE) days to complete healing. Wounds treated with UMF20 healed faster than wounds treated with GH (P = 0.02) and control wounds (P = 0.01). Treatment of wounds with UMF20 reduced overall wound healing time compared with wounds treated with GH and control wounds. However, using this model the difference in the overall time to complete healing was small. © 2017 Australian Veterinary Association.

    We present a new approach which aims to translate freeform biofabrication into the surgical field, while staying true to the practical constraints of the operating theatre. Herein we describe the development of a handheld biofabrication tool, dubbed the ‘biopen’, which enables the deposition of living cells and biomaterials in a manual, direct-write fashion. A gelatin–methacrylamide/hyaluronic acid–methacrylate (GelMa/HAMa) hydrogel was printed and UV crosslinked during the deposition process to generate surgically sculpted 3D structures. Custom titanium nozzles were fabricated to allow printing of multiple ink formulations in a collinear (side-by-side) geometry. Independently applied extrusion pressure for both chambers allows for geometric control of the printed structure and for the creation of compositional gradients. In vitro experiments demonstrated that human adipose stem cells maintain high viability (>97%) one week after biopen printing in GelMa/HAMa hydrogels. The biopen described in this study paves the way for the use of 3D bioprinting during the surgical process. The ability to directly control the deposition of regenerative scaffolds with or without the presence of live cells during the surgical process presents an exciting advance not only in the fields of cartilage and bone regeneration but also in other fields where tissue regeneration and replacement are critical.

    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. © American Academy of Otolaryngology-Head and Neck Surgery Foundation 2015.

  12. Negative pressure therapy for the treatment of complex wounds

    RENAN VICTOR KÜMPEL SCHMIDT LIMA

    Full Text Available ABSTRACT The objective of this study is to evaluate the effectiveness of negative pressure therapy (NPT in the treatment of complex wounds, with emphasis on its mechanisms of action and main therapeutic indications. We searched the Pubmed / Medline database for articles published from 1997 to 2016, and selected the most relevant ones. The mechanisms of action of NPT involveboth physical effects, such as increased perfusion, control of edema and exudate, reduction of wound dimensions and bacterial clearance, and biological ones, such as the stimulation of granulation tissue formation, microdeformations and reduction of Inflammatory response. The main indications of NPT are complex wounds, such as pressure ulcers, traumatic wounds, operative wound dehiscences, burns, necrotizing wounds, venous ulcers, diabetic wounds, skin grafts, open abdomen, prevention of complications in closed incisions and in the association with instillation of solutions in infected wounds.

    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

    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. CO(2) (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 CO(2) 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, CO(2) and reduced pressure delayed dehiscence. CO(2) 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.

    Otitic meningitis in the postantibiotic era is still a serious condition, requiring intensive treatment and prolonged rehabilitation. In view of the significant morbidity and mortality rate, conditions that may increase the likelihood of otitic meningitis developing should be treated promptly. The incidence of meningitis after asymptomatic encephaloceles of the middle cranial fossa varies greatly, and the management differs between elective surgical repair and expectant careful observation. Superior semicircular canal dehiscences (SSCDs) are postulated to have a congenital origin and are associated with a thin or dehiscent tegmen. Several cases of simultaneous SCCD and tegmen defects have been reported, but the findings of otitic meningitis, SCCD, and encephaloceles has, to the best of our knowledge, not been previously explored in the literature. We reviewed a series of 4 patients who all presented with a combination of otitic meningitis, encephaloceles, and SSCD. All the 4 patients we reviewed had meningitis secondary to otitis media with computed tomographic scans confirming the presence of SCCD with ipsilateral tegmen tympani defects and associated cephaloceles. All patients were treated with intravenous antibiotics and underwent surgery that ranged from myringotomy and ventilation tube insertions, mastoidectomy, and burr hole drainage for temporal lobe abscess. They were all associated with intensive care unit admission, significant morbidity, and prolonged hospital stays. There were no mortalities. We propose that in all SSCD patients, a careful computed tomographic examination of the cranial base should be undertaken to exclude other associated tegmen tympani defects. In cases of SSCD requiring surgery, we support the view that elective surgical repair be recommended where asymptomatic ipsilateral encephaloceles are found, to reduce the risk of otitic meningitis.

    An employee of the Valduc Centre (France) suffered an injury to his right thumb when working in a glove-box on a pipeline which had contained a solution of 239 Pu and Am. The lesion was slight but attempts at decontamination were fruitless. The contamination was deep-seated (activity of not less than 18nCi). DTPA was injected intravenously, and it was decided to excise the lesion surgically. Thanks to the quality of its physical facilities and the professional quality of its radiation medicine and surgery team, the Valduc Centre was able to carry out the operation successfully. The result was excellent, and the contamination was eliminated to the satisfaction of both the patient and the physician. (author)

    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 Neurology.org). This pattern of nystagmus aligns in the plane of the dehiscent semicircular canal and is due to excitation of its afferent nerves.

    Superior semicircular canal dehiscence is a newly described syndrome of sound and/or pressure induced vertigo. Computed tomography (CT) imaging plays an important role in confirmation of a defect in the bone overlying the canal. A high resolution CT technique utilising 0.5 mm or thinner slices and multi-planar reconstructions parallel to the superior semicircular canal is required. Placement of a histogram over a suspected defect can assist CT diagnosis

    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.

    To evaluate the safety of electrocautery for coagulation during Caesarean sections. 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. 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). 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.

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

    The surgical closure of orofacial clefts is considered to impair maxillary growth and dento-alveolar development. Wound contraction and subsequent scar tissue formation, during healing of these surgical wounds, contribute largely to these growth disturbances. The potential to minimize wound

    The purpose of this study is to assess the effectiveness of the topical application of cacicol regenerating agent (RGTA) in an experimental model of corneal ulcer after photorefractive keratectomy (PRK) in mice. Mice were subjected to PRK surgery with a 2.0mm ablation zone on the central cornea and 45mm of depth on a VISX Star S2 excimer laser. Corneas were treated topically with cacicol drops 1hour and 48hours after injury. Control groups received balanced salt solution (BSS) in the same dosage. Clinical and histopathological events were evaluated at 1, 2, 3 and 7 days after surgery. Sections obtained through the central region of the corneas were used to analyze the histopathological events of injured and healed corneas. αSMA (myofibroblast transformation), E cadherin (assembly of epithelial cells) and neuronal class III β-tubulin (innervation) were performed. Corneas treated topically with cacicol for 7 days showed a greater degree of transparency compared to controls. cacicol treated corneas showed improved epithelial cytoarchitecture. Analysis of αSMA profiles in the stroma showed that cacicol reduced or delayed the presence of myofibroblasts in the stroma compared to BSS (P<0.001). Finally, a putative neuroregenerative effect of cacicol was found in corneas subjected to an experimental PRK lesion. In some cases some interindividual variability could be observed due to the design of the experimental model. This is a limitation to consider, despite the statistical significance of the data. In a model of laser induced surgical lesions in the cornea, topical application of an RGTA (i.e. cacicol) could be involved in avoiding myofibroblast scarring formation and promoting nerve regeneration.

    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 U.S.A. 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. 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. 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 VAC therapy in the group with exposed graft. VAC therapy is the effective method for care of complicated wounds in vascular surgery.

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

    From 1990 to 1994 at Clinical Hospital Center, Zagreb, 1904 median sternotomies were performed for cardiac operations. Patients shared the same intensive care unit (ICU) with the wounded persons, admitted to the hospital from battlefield. Infection developed in 124 patients, an incidence of 6.51%. Methicillin resistant Staphylococcus aureus (MRSA) was isolated from 90, methicillin resistant Staphylococcus epidermidis (MRSE) from 19, and gram negative bacilli (GNB) from 56 patients, Pseudomonas aeruginosa in 2, and Clostridium pneumoniae in 1 case. Ninety-six patients (5.04%) developed superficial localized infection of subcutaneous tissues and they were treated with frequent dressing changes with antibiotic-soaked gauze in combination with systemic antibiotics. Twenty-eight patients (1.47%) developed mediastinitis and sternal dehiscence. They were treated by operative debridement followed by reclosure of the sternum with continuous antibiotic irrigation. We obtained satisfactory results with our method of closure of sternum which is a modification of Robicsek's technique. Nine of them required further operation. In seven cases we performed muscle flaps and in two omentoplasty. One hundred and twenty patients were discharged in satisfactory condition. The uncontrolled mediastinal sepsis caused death in 4 patients. Higher infection rate after median sternotomy during 1991 and 1992 could be possibly explained with the war circumstances in Croatia, and especially with MRSA strain becoming endemic in surgical ICU.

    Full Text Available PURPOSE: To establish a low-cost method to prepare platelet-rich plasma (PRP and evaluates the potential of platelet derived factors to enhance wound healing in the surgical wounds in equine. METHODS: To obtain a PRP gel, calcium gluconate and autologous thrombin were added to platelet-rich plasma. For the tests six saddle horses were used and two surgical incisions were made in each animal. Wounds were treated with PRP gel or untreated. Sequential wound biopsies collected at Treatment 1: at days 5 and 30 and Treatment 2: at days 15 and 45 post wounding permitted comparison of differentiation markers and wound repair. RESULTS: The optimal platelets enrichment over 4.0 time's baseline values was obtained using 300 g for 10 min on the first centrifugation and 640 g for 10 min on the second centrifugation. CONCLUSION: Wounds treated with PRP gel exhibit more rapid epithelial differentiation and enhanced organization of dermal collagen compared to controls in equineOBJETIVO: Estabelecer um método econômico na preparação de plasma rico em plaquetas (PRP e avaliar se os fatores derivados destas plaquetas aceleram a cicatrização de feridas cirúrgicas em cavalos.

    2016-09-01

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

    Stimulation to bronchial mucosa is one of the major risk factor of asthma attack. When patients receive surgical intervention and general anesthesia, they are always exposed to stimulation to bronchial mucosa. Prevention method of bronchial asthma attack during surgical intervention is not established yet. We investigated that clinical course of patients with bronchial asthma who received general anesthesia and surgical intervention. Seventy-six patients with bronchial asthma were received general anesthesia and surgical intervention from 1993 to 1998. Twenty-four patients were mild asthmatic patients, 39 were moderate asthmatic patients and 13 were severe asthmatic patients. Preoperative treatment for preventing asthma attack was as follows; Eight patients were given intravenous infusion of aminophylline before operation. Fifty-two patients were given intravenous infusion of aminophylline and hydrocortisone before operation. Three patients were given intravenous infusion of hydrocortisone for consecutive 3 days before operation. Thirteen patients were given no treatment for preventing asthma attack. One patient was suffered from asthma attack during operation. She was given no preventing treatment for asthma attack before operation. Three patients were suffered from asthma attack after operation. No wound dehiscence was observed in all patients. To prevent asthma attack during operation, intravenous infusion of steroid before operation is recommended, when patients with asthma receive general anesthesia and surgical intervention.

    persisted next to the cesarean scar, and thus surgical treatment was considered. This video illustrates the laparoscopic resection of a cesarean scar ectopic pregnancy associated with isthmocele repair. The originality of this video lies in the fact that it is the first demonstration of the laparoscopic treatment of total caesarean scar dehiscence. The total operative time was 180 minutes. First, hysteroscopic evaluation revealed the cesarean scar dehiscence and the posterior pole of the ectopic pregnancy. Then the diagnosis of cesarean scar ectopic pregnancy was confirmed laparoscopically. The utero-ombilical truncs were clamped bilaterally. Complete enucleation of pregnancy was achieved after dissection of the vesicouterine peritoneum. Isthmocele repair was performed with closure in 2 planes. A blue dye test confirmed the tightness of the stitches. The utero-ombilical truncs were unclamped, and antiadhesion gel was applied to the new uterine scar [1]. The operation was performed successfully without complications. Intraoperative blood loss was <100 mL. The patient was discharged on postoperative day 3. No immediate complications were noticed. At 1 month after the intervention, ultrasound was normal. Surgical management of caesarean scar ectopic pregnancy with total dehiscence of hysterotomy can be performed safely and efficiently under laparoscopy. Copyright © 2017 AAGL.

    The aim of the present study was to compare bone regeneration in dehiscence-type defects at titanium implants with chemically modified sandblasted/acid-etched (modSLA) or dual acid-etched surfaces with a calcium phosphate nanometre particle modification (DCD/CaP). Buccal dehiscence-type defects were surgically created following implant site preparation in both the upper and the lower jaws of 12 fox hounds. Both types of implants were randomly allocated in a split-mouth design and left to heal in a submerged position for 2 and 8 weeks. Dissected blocks were processed for histomorphometrical analysis [e.g. new bone height (NBH), percentage of bone-to-implant contact (BIC), area of new bone fill (BF), and area of mineralized tissue (MT) within BF]. At 2 and 8 weeks, both groups revealed comparable mean BF (2.3+/-0.6 to 2.5+/-0.6 mm(2)versus 2.0+/-0.6 to 1.4+/-0.5 mm(2)) and MT (31.1+/-14.3-83.2+/-8.2%versus 38.9+/-15.9-84.4+/-6.3%) values. However, modSLA implants revealed significantly higher mean NBH (2.4+/-0.8 to 3.6+/-0.3 mm versus 0.9+/-0.8 to 1.8+/-1.4 mm) and BIC (53.3+/-11.3-79.5+/-6.6%versus 19.3+/-16.4-47.2+/-30.7%) values than DCD/CaP implants. ModSLA implants may have a higher potential to support osseointegration in dehiscence-type defects than DCD/CaP implants.

  17. Incidence of dehiscence of the bony roof of the superior semicircular canal by CT imaging

    Dehiscence of the bony roof of the superior semicircular canal (SSCC) is rare, but it has been recognized by otologists since Minor et al first described superior canal dehiscence syndrome (SCDS). In this study, dehiscence of the bony roof of SSCC was incidentally detected in three patients with benign paroxysmal positional vertigo out of 49 serial patients with vertigo and dizziness by multi-slice computed tomography. Although detection of dehiscence of the SSCC by ultra-high-resolution CT imaging of the temporal bones has been required for a diagnosis of SCDS, this study showed that dehiscence of the bony roof of the SSCC can be an incidental finding and therefore is not specific for SCDS.

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.)

    Postoperative wound disruption is associated with high morbidity and mortality. We sought to identify the risk factors and outcomes of wound disruption following colorectal resection. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was used to examine the clinical data of patients who underwent colorectal resection from 2005 to 2013. Multivariate regression analysis was performed to identify risk factors of wound disruption. We sampled a total of 164,297 patients who underwent colorectal resection. Of these, 2073 (1.3 %) had wound disruption. Patients with wound disruption had significantly higher mortality (5.1 vs. 1.9 %, AOR: 1.46, P = 0.01). The highest risk of wound disruption was seen in patients with wound infection (4.8 vs. 0.9 %, AOR: 4.11, P disruption such as chronic steroid use (AOR: 1.71, P disruption compared to open surgery (AOR: 0.61, P disruption occurs in 1.3 % of colorectal resections, and it correlates with mortality of patients. Wound infection is the strongest predictor of wound disruption. Chronic steroid use, obesity, severe COPD, prolonged operation, non-elective admission, and serum albumin level are strongly associated with wound disruption. Utilization of the laparoscopic approach may decrease the risk of wound disruption when possible.

  1. Temporal Bone Fracture Causing Superior Semicircular Canal Dehiscence

    2014-01-01

    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.

    Preterm, critically ill neonates represent a challenge in wound healing. Many factors predispose infants to skin injuries, including decreased epidermal-dermal cohesion, deficient stratum corneum, relatively alkaline pH of skin surface, impaired nutrition and presence of multiple devices on the skin. We present a case series describing the use of medical-grade honey-Leptospermum honey (Medihoney), for successful treatment of slowly healing neonatal wounds, specifically stage 3 pressure ulcer, dehiscent and infected sternal wound, and full-thickness wound from an extravasation injury.

    Osteomyelitis is common in diabetic foot infections and medical management can lead to poor outcomes. Surgical management involves sending histopathologic and microbiologic specimens which guides future intervention. We examined the effect of obtainment of surgical margins in patients undergoing forefoot amputations to identify patient characteristics associated with outcomes. Secondary aims included evaluating interobserver reliability of histopathologic data at both the distal-to and proximal-to surgical bone margin. Data were prospectively collected on 72 individuals and was pooled for analysis. Standardized method to retrieve intraoperative bone margins was established. A univariate analysis was performed. Negative outcomes, including major lower extremity amputation, wound dehiscence, reulceration, reamputation, or death were recorded. Viable proximal margins were obtained in 63 out of 72 cases (87.5%). Strong interobserver reliability of histopathology was recorded. Univariate analysis demonstrated preoperative platelets, albumin, probe-to-bone testing, absolute toe pressures, smaller wound surface area were associated with obtaining viable margins. Residual osteomyelitis resulted in readmission 2.6 times more often and more postoperative complications. Certain patients were significantly different in the viable margin group versus dirty margin group. High interobserver reliability was demonstrated. Obtainment of viable margins resulted in reduced rates of readmission and negative outcomes. Prognostic, Level I: Prospective.

    Bevacizumab (BEV) is commonly used for treating recurrent glioblastoma (GBM), and wound healing is a well-established adverse event. Retrospective analysis of GBM patients with and without wound healing complications while on BEV treatment is reported. 287 patients identified, majority were males (60 %) with median age of 52.5 years. 14 cases identified with wound healing problems, related to either craniotomy (n = 8) or other soft tissue wounds (n = 6). Median duration of BEV treatment to complication was 62 days (range 6-559). Majority received 10 mg/kg (n = 11) and nine (64.3 %) were on corticosteroids, with median daily dose of 6 mg (range 1-16 mg) for median of 473 days before starting BEV. For dehisced craniotomy wounds, median time for starting BEV from last surgery was 29 days (range 27-345). Median time from starting BEV to developing wound complication was 47 days (range 16-173). Seven (87.5 %) had infected wounds requiring antibiotics, hospitalization. Four (50 %) required plastic surgery. BEV stopped and safely resumed in 6 (75 %) patients; median delay was 70 days (range 34-346). Soft tissue wounds included decubitus ulcer, dehisced striae, herpes simplex, trauma to hand and back, and abscess. Median time from starting BEV to wound issues was 72 days (range 6-559). Five (83.3 %) were infected, requiring antibiotics. While three (50 %) required hospitalization, none required plastic surgery. Treatment stopped in five (83.3 %) and restarted in two (median delay 48 days, range 26-69). Wound healing complications are uncommon but associated with significant morbidity. Identifying those at risk and contributing factors warrants further investigation.

    Full Text Available OBJECTIVE: To evaluate the results of subcostal incisional hernia repair using polypropylene mesh, the technical aspects of musculo-aponeurotic reconstruction, routine fixation of supra-aponeurotic mesh and follow-up for five years.METHODS: We conducted a retrospective study that assessed 24 patients undergoing subcostal incisional hernia repair with use of polypropylene mesh; 15 patients (62.5% were female; ages ranged from 33 to 82, and 79.1% had comorbidities.RESULTS: Early complications: three cases (12.5% of wound infection, three cases (12.5% of seroma, one case (4.1% of hematoma; and one case (4.1% of wound dehiscence. Late complications occurred in one case (4.1% of hernia recurrence attributed to technical failure in the fixation of the mesh and in one case (4.1% of chronic pain. There were no cases of exposure or rejection of the mesh.CONCLUSION: The subcostal incisional hernia, though not very relevant, requires adequate surgical treatment. Its surgical correction involves rebuilding the muscle-aponeurotic defect, supra-aponeurotic fixation of polypropylene mesh, with less complexity and lower rates of complications and recurrences.

    Patients with anophthalmic or phthisis socket suffer from cosmetic problems. To resolve those problems, the authors present the surgical outcomes of deep superior sulcus (DSS) augmentation using acellular dermal matrix in patients with anophthalmic or phthisis socket. The authors retrospectively reviewed anophthalmic or phthisis patients who underwent surgery for DSS augmentation using acellular dermal matrix. To evaluate surgical outcomes, the authors focused on 3 aspects: the possibility of wearing contact prosthesis, the degree of correction of the DSS, and any surgical complications. The degree of correction of DSS was classified as excellent: restoration of superior sulcus enough to remove sunken sulcus shadow; fair: gain of correction effect but sunken shadow remained; or fail: no effect of correction at all. Ten eyes of 10 patients were included. There was a mean 21.3 ± 37.1-month period from evisceration or enucleation to the operation for DSS augmentation. All patients could wear contact prosthesis after the operation (100%). The degree of correction was excellent in 8 patients (80%) and fair in 2. Three of 10 (30%) showed complications: eyelid entropion, upper eyelid multiple creases, and spontaneous wound dehiscence followed by inflammation after stitch removal. Uneven skin surface and paresthesia in the forehead area of the affected eye may be observed after surgery. The overall surgical outcomes were favorable, showing an excellent degree of correction of DSS and low surgical complication rates. This procedure is effective for patients who have DSS in the absence or atrophy of the eyeball.

    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.

    Full Text Available Objective: The dehiscent facial nerve canal has been well documented in histopathological studies of temporal bones as well as in clinical setting. We describe clinical and radiologic features of a child with recurrent facial nerve palsy and dehiscent facial nerve canal. Methods: Retrospective chart review. Results: A 5-year-old male was referred to the otolaryngology clinic for evaluation of recurrent acute otitis media and hearing loss. He also developed recurrent left peripheral FN palsy associated with episodes of bilateral acute otitis media. High resolution computed tomography of the temporal bones revealed incomplete bony coverage of the tympanic segment of the left facial nerve. Conclusions: Recurrent peripheral FN palsy may occur in children with recurrent acute otitis media in the presence of a dehiscent facial nerve canal. Facial nerve canal dehiscence should be considered in the differential diagnosis of children with recurrent peripheral FN palsy.

    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.)

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

    Full Text Available 'Taishanzaoxia' fruit rapid softening and dehiscence during ripening stage and this process is very sensitive to endogenous ethylene. In this study, we cloned five ethylene signal transcription factors (ZMdEIL1, ZMdEIL2, ZMdEIL3, ZMdERF1 and ZMdERF2 and one functional gene, ZMdPG1, encoding polygalacturonase that could loose the cell connection which associated with fruit firmness decrease and fruit dehiscence to illustrate the reasons for this specific fruit phenotypic and physiological changes. Expression analysis showed that ZMdERF1 and ZMdEIL2 transcription were more abundant in 'Taishanzaoxia' softening fruit and dehiscent fruit and their expression was inhibited by an ethylene inhibitor 1-methylcyclopropene. Therefore, ZMdERF1 and ZMdEIL2 expression were responses to endogenous ethylene and associated with fruit softening and dehiscence. ZMdPG1 expression was induced when fruit softening and dehiscence but this induction can be blocked by 1-MCP, indicating that ZMdPG1 was essential for fruit softening and dehiscence and its expression was mediated by the endogenously occurred ethylene. ZMdPG1 overexpression in Arabidopsis led to silique early dehiscence while suppressing ZMdPG1 expression by antisense ZMdPG1 prevented silique naturally opening. The result also suggested that ZMdPG1 related with the connection between cells that contributed to fruit softening and dehiscence. ZMdERF1 was more closely related with ethylene signaling but it was not directly regulated the ZMdPG1, which might be regulated by the synergic pattern of ethylene transcription factors because of both the ZMdERF1 and ZMdERF2 could interact with ZMdEIL2.

    Eagle syndrome (ES) is an uncommon complication of styloid process elongation with stylohyoideal complex symptomatic calcification. It is an uncommon condition (4% of the population) that is symptomatic in only 4% of the cases. Eagle syndrome is usually an acquired condition that can be related to tonsillectomy or to a neck trauma. A type of ES is the styloid-carotid syndrome, a consequence of the irritation of pericarotid sympathetic fibers and compression on the carotid artery. Clinical manifestations are found most frequently after head turning and neck compression. Although conservative treatment (analgesics, anticonvulsants, antidepressants, local infiltration with steroids, or anesthetic agents) have been used, surgical treatment is often the only effective treatment in symptomatic cases. We present the case of a 55-year-old patient, successfully treated under endotracheal anesthesia. The cranial portion of the calcified styloid process was shortened through an external approach, using a piezoelectric cutting device (Piezosurgery Medical II; Mectron Medical Technology, Carasco, Italy) with MT1-10 insert, pump level 4, vibration level 7. No major postoperative complications such as nerve damage, hematoma, or wound dehiscence occurred. After 6 months, the patient was completely recovered. Two years after the surgery, the patient did not refer any symptoms related to ES. The transcervical surgical approach in patients with ES seems to be safe and effective, despite the remarkable risk for transient marginal mandibular nerve palsy. This risk can be decreased by the use of the piezoelectric device for its distinctive characteristics--such as precision, selective cut action, and bloodless cut.

    to evaluate the return to sport after surgical treatment for pubalgia among 30 professional soccer players and describe the surgical technique used. this case series was evaluated by means of a questionnaire and physical examination on 30 male professional soccer players of mean age 24.4 years (range: 18-30). The mean duration of the symptoms was 18.6 months (range: 13-28). The diagnosis was made through clinical investigation, special maneuvers and complementary examinations, by the same examiner. All the patients underwent surgical treatment after conservative treatment failed; all procedures were performed by the same surgeon using the same technique. Nonparametric comparisons were made to investigate the time taken to recover after the surgery, for the patients to return to their sport. five patients evolved with hematoma, with the need to remove the stitches three weeks after the operation because of a small dehiscence at the site of the operative wound. The wound healed completely in all these cases by five weeks after the surgery. Four patients presented dysuria in the first week, but improved in the second postoperative week. The mean time taken to return to training was around eight weeks (range: seven-nine). All the players returned to competitive soccer practice within 16 weeks. When asked about their degree of satisfaction after the operation (satisfied or dissatisfied), taking into consideration their return to the sport, there was 100% satisfaction, and they returned to professional practice at the same competitive level as before the injury. This degree of satisfaction continued to the last assessment, which was made after 36 months of postoperative follow-up. the surgical technique presented in this case series, with trapezoidal resection of the pubic symphysis in association with bilateral partial tenotomy of the long adductor, was a fast and effective procedure with a low rate of postoperative complications. It was shown to be an excellent

    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.

    Objective: To compare the Vacuum Assisted Closure (Vac) wound therapy with Conventional Gauze Therapy (CGT) in management of acute traumatic wounds on the basis of time taken to achieve a vital red wound ready for definitive surgical closure. Study Design: Randomized control trial. Place and Duration of Study: Department of Surgery Combined Military Hospital Rawalpindi from Mar 2009 to Sep 2009. Patients and Methods: This study included 82 patients of acute traumatic wounds. Patients were randomly allotted to group A, in which wound was treated with new method of vacuum assisted closure (VAC) wound therapy and to group B, in which wound was managed by conventional gauze therapy (CGT). Outcomes were measured by the presence of vital red wound ready to be closed by surgical intervention. Patients with concomitant systemic pathology were not included in study. Results: Comparison between the two groups revealed mean time for wound healing 13 days in group A and 16.9 days in group B with significant difference (p value =0.029). Conclusion: Vacuum assisted closure wound therapy is an effective method in reducing time of wound healing for definitive surgical closure. (author)

    Full Text Available Wound healing and reduction of its recovery time is one of the most important issues in medicine. Wound is defined as disruption of anatomy and function of normal skin. This injury could be the result of physical elements such as  surgical incision, hit or pressure cut of the skin and gunshot wound. Chemical or caustic burn is another category of wound causes that can be induced by acid or base contact irritation. Healing is a process of cellular and extracellular matrix interactions that occur in the damaged tissue. Wound healing consists of several stages including hemostasis, inflammatory phase, proliferative phase and new tissue formation which reconstructs by new collagen formation. Wounds are divided into acute and chronic types based on their healing time. Acute wounds have sudden onset and in normal individuals usually have healing process of less than 4 weeks without any residual side effects. In contrast, chronic wounds have gradual onset. Their inflammatory phase is prolonged and the healing process is stopped due to some background factors like diabetes, ischemia or local pressure. If the healing process lasts more than 4 weeks it will be classified as chronic wound. Despite major advances in the treatment of wounds, still finding effective modalities for healing wounds in the shortest possible time with the fewest side effects is a current challenge. In this review different phases of wound healing and clinical types of wound such as venous leg ulcer, diabetic foot ulcer and pressure ulcer are discussed. Also acute wound models (i.e burn wounds or incisional wound and chronic wound models (such as venous leg ulcers, diabetic foot ulcer, pressure ulcers or bedsore in laboratory animals are presented. This summary can be considered as a preliminary step to facilitate designing of more targeted and applied research in this area.

    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.

    2013-06-01

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

She presented with a painful ulcer on her right lower abdomen. She also presented with multiple scars, skin grafts on the extremities, and a missing left lower leg, the causes for all of which were unexplained. The results of her blood test were normal, except for the hemoglobin level. Histology of the skin biopsy specimen from the ulcer did not show any specific findings. The previous surgeon who had performed the laparoscopic cholecystectomy revealed that surgical wound dehiscence had occurred during her admission. After a body restraint had been applied, the ulcer improved. Medical records indicated that she had been admitted to the department of plastic surgery at our hospital for skin grafting of a leg ulcer. During that admission, she refused to consult with the department of psychiatry, although the staff suspected mental disorders. Therefore, we diagnosed her with cutaneous Munchausen syndrome. After vacuum-assisted closure (VAC therapy had been performed to prevent her from traumatizing the ulcer again, it rapidly became granulated and reepithelialized.

    Cotton gauze with alpha cyanoacrylate was used for alveolopalatal wound dressing after alveolar bone grafting to treat 93 alveolar clefts in 74 cleft patients to reduce mechanical injuries, tension for wound dehiscence, and adhesion of food remnants. T-shaped cotton gauze was put on the gingivoperiosteal flaps and was impregnated with cyanoacrylate. The procedure required no preoperative preparation and its intraoperative execution took less than 5 minutes. The gauze with cyanoacrylate was removed approximately 1 week after surgery. No infection was observed at any of the operational sites, but tiny fistulas developed at four of them. The mean bone graft score was 1.4 point. No complications such as thermal injury resulted from the use of cyanoacrylate. Gauze impregnated with cyanoacrylate proved to be a convenient and dependable dressing for alveolopalatal wounds resulting from gingivoperiosteoplasty for alveolar bone grafting.

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

    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.

    Humanitarian organisations commonly provide reconstructive treatment for patients with cleft lip within developing countries, but follow-up is often non-existent, particularly for those living in rural areas. This study aimed to assess whether a single surgical intervention was sufficient to produce an observable change to the life of a patient with cleft lip living in rural Hararghe in eastern Ethiopia. 356 patients with isolated cleft lips, who received a single surgical treatment at least 6 months previously, were evaluated in 21 rural health centres. Patients and their families expressed unhappiness before treatment, mainly because the society reacted negatively towards the deformities, isolating the patients from community activities. Postoperatively, the percentage of school-aged children participating in education increased from 46% to 79%, some older patients were able to marry, but employment was unaffected. The prevalence of wound dehiscence in the lip repair was 3% and occurred more frequently in patients with a bilateral cleft lip compared to a unilateral cleft lip (p charitable organisations treating rural patients and that the majority of patients report a positive impact following surgical intervention.

    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.

    The objective of this study is to report the surgical outcome after middle fossa approach (MFA) plugging in patients suffering from a superior semi-circular canal dehiscence (SCD) syndrome. This is a retrospective case review. Tertiary referral center. Sixteen ears in 13 patients with a SCD syndrome suffering from severe and disabling vestibular symptoms with a bony dehiscence on CT scan >3 mm and decreased threshold of cervical vestibular evoked potentials (cVEMPs). We assessed preoperatively: clinical symptoms, hearing, cVEMPs threshold, size of dehiscence and videonystagmography (VNG) with caloric and 100 Hz vibratory tests. Postoperatively, we noted occurrences of neurosurgical complication, evolution of audiological and vestibular symptoms, and evaluation of cVEMP data. Tullio's phenomenon was observed in 13 cases (81.3 %) and subjectively reported hearing loss in seven (43.7 %). All patients were so disabled that they had to stop working. No neurosurgical complications were observed in the postoperative course. In three cases (16.6 %), an ipsilateral and transitory immediate postoperative vestibular deficit associated with a sensorineural hearing loss (SNHL) was noted, which totally resolved with steroids and bed rest. All patients were relieved of audiological and vestibular symptoms and could return to normal activity with a mean follow-up of 31.1 months (range 3-95). No patient had residual SNHL. cVEMPs were performed in 14 ears postoperatively and were normalized in 12 (85.7 %). Two of the three patients operated on both sides kept some degree of unsteadiness and oscillopsia. MFA plugging of the superior semi-circular canal is an efficient and non-hearing deteriorating procedure.

    Surgery in combination with radiotherapy (RT) has become the standard of care for most soft tissue sarcomas. The choice between pre- and postoperative RT is controversial. Preoperative RT is associated with a 32-35% rate of major wound complications (MWC) and 16-25% rate of reoperation. The role of vascularized soft tissue "flaps" in reducing complications is unclear. We report the outcomes of patients treated with preoperative RT, resection, and flap reconstruction. 122 treatment episodes involving 117 patients were retrospectively reviewed. All patients were treated with 50.4 Gy of external beam radiation. Surgery was performed at 4-8 weeks after completion of RT by the same combination of orthopedic oncology and plastic reconstructive surgeon. Defects were reconstructed with 64 free and 59 pedicled/local flaps. 30 (25%) patients experienced a MWC and 17 (14%) required further surgery. 20% of complications were exclusively related to the donor site. There was complete or partial loss of three flaps. There was no difference in the rate of MWC or reoperation for complications with respect to age, sex, tumor site, previous unplanned excision, tumor grade, depth, and type of flap. Tumor size ≥8 cm was associated with a higher rate of reoperation (11/44 vs 6/78; P  = 0.008) but the rate of MWC was not significant (16/44 vs 14/78; P  = 0.066). The use of soft tissue flaps is associated with a low rate of MWC and reoperation. Our results suggest that a high rate of flap usage may be required to observe a reduction in complication rates.

    Treatment of soft tissue defects with exposed bones and joints, resulting from trauma, infection, and surgical complications, represents a major challenge. The introduction of negative pressure wound therapy has changed many wound management practices. Negative pressure wound therapy has recently been used in the orthopedic field for management of traumatic or open wounds with exposed bone, nerve, tendon, and orthopedic implants. This article describes a case of a patient with a large soft tissue defect and exposed knee joint, in which negative pressure wound therapy markedly improved wound healing. A 50-year-old man presented with an ulceration of his left knee with exposed joint, caused by severe wound infections after open reduction and internal fixation of a patellar fracture. After 20 days of negative pressure wound therapy, a granulated wound bed covered the exposed bones and joint.To our knowledge, this is the first report of negative pressure wound therapy used in a patient with a large soft tissue defect with exposed knee joint. Despite the chronic wound secondary to infection, healing was achieved through the use of the negative pressure wound therapy, thus promoting granulation tissue formation and closing the joint. We suggest negative pressure wound therapy as an alternative option for patients with lower limb wounds containing exposed bones and joints when free flap transfer is contraindicated. Our result added to the growing evidence that negative pressure wound therapy is a useful adjunctive treatment for open wounds around the knee joint. Copyright 2011, SLACK Incorporated.

    Conclusion: Cochlear-facial dehiscence can predispose patients to post-implant FNS. Prior temporal bone irradiation may carry a higher risk of FNS. We recommend scrutiny for CFD in CTs of CI candidates and appropriate risk counseling for FNS if CFD is discovered and more frequent monitoring for FNS by audiology.

  18. The Effect of Superior Semicircular Canal Dehiscence on Intracochlear Sound Pressures

    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 is not fully understood. We use intracochlear sound pressure measurements in cadaveric preparations to study the effects of SCD size. Simultaneous measurement of basal intracochlear sound pressures in scala vestibuli (SV) and scala tympani (ST) quantifies the complex differential pressure across the cochlear partition, the stimulus that excites the partition. Sound-induced pressures in SV and ST, as well as stapes velocity and ear-canal pressure are measured simultaneously for various sizes of SCD followed by SCD patching. At low frequencies (<600 Hz) our results show that SCD decreases the pressure in both SV and ST, as well as differential pressure, and these effects become more pronounced as dehiscence size is increased. For frequencies above 1 kHz, the smallest pinpoint dehiscence can have the larger effect on the differential pressure in some ears. These effects due to SCD are reversible by patching the dehiscence.

    Immediate implant therapy involving implants placed into intact Type 1 extraction sockets has become a consistent clinical technique. The classification of Type 2 extraction sockets, where the mucosal tissues are present but there is a midfacial osseous dehiscence defect, has been described according to the extent of the buccal bone plate absence. The literature has offered different techniques in the treatment of Type 2 sockets; however, the extent of the defect has never been defined or delineated. In this article, the authors describe a subclassification of Type 2 sockets: Type 2A presents with a dehiscence defect roughly 5 mm to 6 mm from the free gingival margin (FGM) involving the coronal one-third of the labial bone plate; Type 2B presents with a dehiscence defect involving the middle one-third of the labial plate, approximately 7 mm to 9 mm from the FGM; and in Type 2C the dehiscence defect involves the apical one-third of the labial osseous plate roughly 10 mm or greater from the FGM. The authors also offer a protocol and technique employing immediate implant placement, guided bone regeneration, and bone graft containment with a custom two-piece healing abutment that can lead to consistent and satisfactory clinical outcomes in low-smile-line patients. The treatment protocol and sequence is outlined in a clinical case presentation involving a Type 2B socket.

    To measure the buccal plate reconstruction of extraction sockets with labial plate dehiscence defects using a bone allograft in combination with an absorbable collagen membrane and a custom-healing abutment at the time of tooth removal. Ten patients underwent immediate implant placement and reconstruction of the buccal plate. Cone beam computed tomography (CBCT) was performed preextraction, immediately after bone grafting and implant placement (day 0), and between 6 and 9 months following implant surgery. Measurements were taken at three levels: coronal (L1), middle (L2), and apical (L3) level. Implants placed into sockets with labial plate dehiscence defects demonstrated radiographic reformation of the labial plate dehiscence defect at 6 to 9 months posttreatment. The net gain in labial plate on cone beam computerized tomography (CBCT) in L1 and L2 was 3.0 mm, where 0 mm existed at pretreatment. The minimum amount of labial plate thickness of 2.0 mm was achieved in all treated sites, evaluated radiographically at 6 to 9 months postoperatively, in a single procedure, without flap elevation and maintaining the gingival architecture and satisfactory esthetics. Placing an absorbable membrane, bone graft, and custom-healing abutment at the time of flapless anterior tooth extraction and immediate implant placement into a socket with a labial osseous dehiscence is a viable clinical technique to reconstitute the absence of the labial bone plate. © 2015 Wiley Periodicals, Inc.

    Patients with posterior semicircular canal dehiscence (PSCD) have low frequency conductive hearing loss similar to patients with superior semicircular canal dehiscence (SSCD) secondary to a pathologic third window. PSCD can result in conductive hearing loss, but the magnitude of this hearing loss remains to be quantified. Patients with SSCD have been shown to have low frequency conductive hearing loss. The underlying pathophysiology of hearing loss from PSCD and SSCD is similar and related to a pathologic third window. A PubMed search was completed for a meta-analysis of patients with PSCD. Articles with quality audiograms were obtained. Air conduction thresholds for ears with posterior semicircular canal dehiscence were compared to the opposite ear as well as normal control data. Eight articles with 21 patients with PSCD and quality audiograms were included. Two patients had bilateral PSCD and one of those was excluded because hearing thresholds were at the limit of the audiometer. Patients with posterior semicircular canal dehiscence have statistically significant lower air conduction thresholds in frequencies at and below 2000 Hz.

    Chronic wounds such as diabetic foot wounds are a tremendous burden to the health care system and often require a multidisciplinary approach to prevent amputations. Advanced technologies such as negative pressure wound therapy (NPWT) and bioengineered tissues have been successfully used in the treatment of these types of complex wounds. However, the introduction of NPWT with instillation (NPWTi) has provided an alternative treatment for treating complex and difficult-to-heal wounds. This article provides an overview of NPWT and the new NPWTi system and describes preliminary experience using NPWTi on patients with complicated infected diabetic foot wounds after surgical debridement and in a multidisciplinary setting. © 2013 The Author.

    Wound care is a classic example of a surgical realm with a great variation in care. The diversity in wounds and wound treatments, the limited amount of convincing evidence, and the diverging opinions among doctors and nurses involved in wound care contribute to this undesirable variation in care.

  5. SONOGRAPHIC PREDICTION OF SCAR DEHISCENCE IN WOMEN WITH PREVIOUS CAESAREAN SECTION

    Full Text Available BACKGROUND Caesarean section (Sectio Caesarea is a surgical method for the completion of delivery. After various historical modifications of operative techniques, modern approach consists in the transverse dissection of the anterior wall of the uterus. The rate of vaginal birth after caesarean section was significantly reduced from year to year and the rate of repeated caesarean section is increased during the past 10 years. Evaluation of scar thickness is done by ultrasound, but it is still debatable size of thick scar that would be guiding “cut-off value” for the completion of the delivery method. To better assess the risk of uterine rupture, some authors have proposed sonographic measurement of lower uterine segment thickness near term assuming that there is an inverse correlation between LUS thickness and the risk of uterine scar defect. Therefore, this assessment for the management of women with prior CS may increase safety during labour by selecting women with the lowest risk of uterine rupture. The aim of the study is to study the diagnostic accuracy of sonographic measurements of the Lower Uterine Segment (LUS thickness near term in predicting uterine scar defects in women with prior Caesarean Section (CS. We aim to ascertain the best cut-off values for predicting uterine rupture. MATERIALS AND METHODS 100 antenatal women with history of previous one LSCS who come to attend antenatal clinic will be assessed for scar thickness by transabdominal ultrasonography and its correlation with intraoperative findings. This prospective longitudinal study was conducted for 1 year after IEC approval with inclusion criteria previous one LSCS. Exclusion criteria- 1 Previous myomectomy scar; 2 Previous 2 LSCS; 3 Previous hysterotomy scar. RESULTS Our findings indicate that there is a strong association between degree of LUS thinning measured near term and the risk of uterine scar defect at birth. In our study, optimal cut-off value for predicting

    The aim of this study is to appreciate the incidence of patients with isolated conductive hearing loss with normal drum due to superior semicircular canal dehiscence (SCD). It is a prospective radiological study. Two hundred and seventy-two patients with a normal drum suffering from isolated unilateral or bilateral conductive or mixed hearing loss were included in a prospective radiological study. A high resolution computerized tomography (HRCT) was performed in all the patients. Those who were found to have a unilateral or bilateral SCD underwent further etiological, clinical, audiologic evaluation. Ten patients with conductive or mixed hearing loss were found to have a unilateral or bilateral SCD. The disease was bilateral in five cases, and most often associated with a dehiscence of the tegmen tympani on both sides, supporting the theory of the congenital nature of the disease. There was no clear correlation between symptoms and the size of the SCD. Because patients were not suffering from incapacitating vestibular symptoms, they were not operated for surgical occlusion of the SCD, and were referred to a hearing aid specialist to improve hearing. Conductive or mixed hearing loss due to SCD is relatively frequent, justifying in our opinion that a systematic HRCT be carried out before surgery of any patient with conductive hearing loss.

    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.

    The aim of the study was to update the clinical database of chronic wounds in order to derive an evidence based understanding of the condition and hence to guide future clinical management in China. A total of 241 patients from January 1, 2011 to April 30, 2016 with chronic wounds of more than 2 weeks' duration were studied in wound healing department in Shanghai. Results revealed that among all the patients the mean age was 52.5 ± 20.2 years (range 2-92 years). The mean initial area of wounds was 30.3 ± 63.0 cm 2 (range 0.25-468 cm 2 ). The mean duration of wounds was 68.5 ± 175.2 months (range 0.5-840 months). The previously reported causes of chronic wounds were traumatic or surgical wounds (n = 82, 34.0%), followed by pressure ulcers (n = 59, 24.5%). To study the effects of age, patients were divided into 2 groups: less than 60 years (wounds etiology between the 2 age groups was analyzed, and there was significant statistical difference ( P wounds, chi-square test was used. There were significant differences in the factor of wound infection. ( P = .035, 95% CI = 0.031-0.038) Regarding therapies, 72.6% (n = 175) of the patients were treated with negative pressure wound therapy. Among all the patients, 29.9% (n = 72) of them were completely healed when discharged while 62.7% (n = 150) of them improved. The mean treatment cost was 12055.4 ± 9206.3 Chinese Yuan (range 891-63626 Chinese Yuan). In conclusion, traumatic or surgical wounds have recently become the leading cause of chronic wounds in Shanghai, China. Etiology of the 2 age groups was different. Infection could significantly influence the wound outcome.

    To investigate the aesthetic effect of wound repair with flaps. One thousand nine hundred and ninety-six patients with 2082 wounds hospitalized from January 2004 to December 2011. These wounds included 503 deep burn wounds, 268 pressure sores, 392 soft tissue defects caused by trauma, 479 soft tissue defects due to resection of skin cancer and mole removal, 314 soft tissue defects caused by scar excision, and 126 other wounds. Wound area ranged from 1.5 cm x 1.0 cm to 30.0 cm x 22.0 cm. Sliding flaps, expanded flaps, pedicle flaps, and free flaps were used to repair the wounds in accordance with the principle and timing of wound repair with flaps. Five flaps showed venous congestion within 48 hours post-operation, 2 flaps of them improved after local massage. One flap survived after local heparin wet packing and venous bloodletting. One flap survived after emergency surgical embolectomy and bridging with saphenous vein graft. One flap showed partial necrosis and healed after skin grafting. The other flaps survived well. One thousand three hundred and twenty-one patients were followed up for 3 months to 2 years, and flaps of them were satisfactory in shape, color, and elasticity, similar to that of normal skin. Some patients underwent scar revision later with good results. Application of suitable flaps in wound repair will result in quick wound healing, good function recovery, and satisfactory aesthetic effect.

    Full Text Available Abstract Background Median sternotomy infection and bony nonunion are two commonly described complications which occur in 0.4 - 5.1% of cardiac procedures. Although relatively infrequent, these complications can lead to significant morbidity and mortality. The aim of this retrospective study is to evaluate the initial experience of a transverse plate fixation system following wound complications associated with sternal dehiscence with or without infection following cardiac surgery. Methods A retrospective chart review of 40 consecutive patients who required sternal wound reconstruction post sternotomy was performed. Soft tissue debridement with removal of all compromised tissue was performed. Sternal debridement was carried using ronguers to healthy bleeding bone. All patients underwent sternal fixation using three rib plates combined with a single manubrial plate (Titanium Sternal Fixation System®, Synthes. Incisions were closed in a layered fashion with the pectoral muscles being advanced to the midline. Data were expressed as mean ± SD, Median (range or number (%. Statistical analyses were made by using Excel 2003 for Windows (Microsoft, Redmond, WA, USA. Results There were 40 consecutive patients, 31 males and 9 females. Twenty two patients (55% were diagnosed with sternal dehiscence alone and 18 patients (45% with associated wound discharge. Thirty eight patients went on to heal their wounds. Two patients developed recurrent wound infection and required VAC therapy. Both were immunocompromised. Median post-op ICU stay was one day with the median hospital stay of 18 days after plating. Conclusion Sternal plating appears to be an effective option for the treatment of sternal wound dehiscence associated with sternal instability. Long-term follow-up and further larger studies are needed to address the indications, benefits and complications of sternal plating.

    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.

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

    To evaluate the incidence and CT findings of the medial depression and bony dehiscence of lamina papyracea as an anatomic variation. 1472 PNS CTs of the patients with symptoms of chronic sinusitis were retrospectively evaluated. The total incidence of depressed lamina papyracea as an anatomic variation was 3.5%(52/1472) on PNS CT. There was a statistically significant correlation between the increasing age and the incidence of depressed lamina papyracea. Depression of lamina papyracea anterior to the basal lamella were more common than those of the posterior depression. Associated findings were herniation of adjacent fatty tissue in all cases and the medial bowing and hypertrophied configuration of the medial rectus muscle without significant herniation in 19 cases(34%). Nontraumatic, asymptomatic depression with bony dehiscence of lamina papyracea as an anatomic variation is not uncommon with the incidence of 3.5%. Recognition of its existence and degree may be helpful in avoiding various ocular complication during ethmoid surgery

    2006-05-01

    In 2003, it was reported that superior semicircular canal dehiscence can mimic otosclerosis because of low-frequency bone conduction hearing gain and dissipation of air-conducted acoustic energy through the dehiscence. We report the case of a 17-year-old girl with left-sided combined hearing loss thought to be due to otosclerosis. Bone conduction thresholds were -10 dB at 250 and 500 Hz and she had a 40 dB air-bone gap at 250 Hz. When a tuning fork was placed at her ankle she heard it in her left ear. Acoustic reflexes and vestibular evoked myogenic potentials could be elicited bilaterally. Imaging of the temporal bones showed no otosclerosis, superior semicircular canal dehiscence or large vestibular aqueduct, but a left-sided, Mondini-like dysplasia of the cochlea with a modiolar deficiency could be seen. Mondini-like cochlear dysplasia should be added to the causes of inner-ear conductive hearing loss.

    Pulsatile tinnitus is experienced by most patients with idiopathic intracranial hypertension. The pathophysiology remains uncertain; however, transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence have been proposed as potential etiologies. We aimed to determine whether the prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence was increased in patients with idiopathic intracranial hypertension and pulsatile tinnitus relative to those without pulsatile tinnitus and a control group. CT vascular studies of patients with idiopathic intracranial hypertension with pulsatile tinnitus ( n = 42), without pulsatile tinnitus ( n = 37), and controls ( n = 75) were independently reviewed for the presence of severe transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence according to published criteria. The prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence in patients with idiopathic intracranial hypertension with pulsatile tinnitus was compared with that in the nonpulsatile tinnitus idiopathic intracranial hypertension group and the control group. Further comparisons included differing degrees of transverse sinus stenosis (50% and 75%), laterality of transverse sinus stenosis/sigmoid sinus diverticulum/dehiscence, and ipsilateral transverse sinus stenosis combined with sigmoid sinus diverticulum/dehiscence. Severe bilateral transverse sinus stenoses were more frequent in patients with idiopathic intracranial hypertension than in controls ( P tinnitus within the idiopathic intracranial hypertension group. Sigmoid sinus dehiscence (right- or left-sided) was also more common in patients with idiopathic intracranial hypertension compared with controls ( P = .01), but there was no significant association with pulsatile tinnitus within the idiopathic intracranial hypertension group. While our data corroborate previous studies demonstrating increased prevalence of sigmoid sinus diverticulum/dehiscence

    Risk factors for post-cesarean wound infection, but not disruption, are well-described in the literature. The primary objective of this study was to identify risk factors for non-infectious post-cesarean wound disruption. Secondary analysis was conducted using data from a single-center randomized controlled trial of staple versus suture skin closure in women ≥24 weeks' gestation undergoing cesarean delivery. Wound disruption was defined as subcutaneous skin or fascial dehiscence excluding primary wound infections. Composite wound morbidity (disruption or infection) was examined as a secondary outcome. Patient demographics, medical co-morbidities, and intrapartum characteristics were evaluated as potential risk factors using multivariable logistic regression. Of the 398 randomized patients, 340, including 26 with disruptions (7.6%) met inclusion criteria and were analyzed. After multivariable adjustments, African-American race (aOR 3.9, 95% CI 1.1-13.8) and staple - as opposed to suture - wound closure (aOR 5.4, 95% CI 1.8-16.1) remained significant risk factors for disruption; non-significant increases were observed for body mass index ≥30 (aOR 2.1, 95% CI 0.6-7.5), but not for diabetes mellitus (aOR 0.9, 95% CI 0.3-2.9). RESULTS for composite wound morbidity were similar. Skin closure with staples, African-American race, and considering the relatively small sample size, potentially obesity are associated with increased risk of non-infectious post-cesarean wound disruption.

  1. Disinfecting wounds with radiation

    Infection with clostridium bacteria, which live in the soil, is most often associated with war wounds, car accidents, complicated abortions, etc. The incidence is highest in areas with poor access to proper wound care. Such infections lead to gas gangrene, a deadly disease that spreads very quickly in the body and causes rapid death. Present-day treatment consists of administering antibiotics and surgical removal of dead, damaged and infected tissue. Amputation is usually necessary to control the spread of the infection, which can advance at the rate of six inches per hour. Before the 1940s, this disease was treated successfully with low doses (50 rad) of radiation (X-rays) in the area of infection. A review of 364 cases treated in this manner, from 1928 until 1940, indicated that patient mortality would be reduced from 50 percent (or higher) to ∼5 percent if patients were treated reasonably early and with the correct technique. X-ray therapy stopped the infection without the need for amputation to control its spread. Low-dose irradiation (LDI) therapy, given immediately, acted as a prophylaxis to prevent the onset of gas gangrene. This is but one example of the extensive use of radiation treatment of many types of infections, before the advent of antibiotics. Low doses are inadequate to kill invading bacteria directly, however, they will stimulate our defences to destroy the infection. The observed beneficial effects are consistent with the large amount of scientific evidence of radiation hormesis - the stimulation of an organism's own defences by low doses of radiation (to destroy invaders and heal wounds). In view of the ineffectiveness of antibiotics in many cases and the evolution of antibiotic-resistant strains of bacteria, physicians should start to use LDI therapies again. Many patients would benefit greatly. (author)

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

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

    Asynchronous flowering of Brassica napus (canola) leads to seeds and siliques at varying stages of maturity as harvest approaches. This range of maturation can result in premature silique dehiscence (pod shattering), resulting in yield losses, which may be worsened by environmental stresses. Therefore, a goal for canola crop improvement is to reduce shattering in order to maximize yield. We performed a comprehensive transcriptome analysis on the dehiscence zone (DZ) and valve of Arabidopsis and Brassica siliques in shatter resistant and sensitive genotypes at several developmental stages. Among known Arabidopsis dehiscence genes, we confirmed that homologs of SHP1/2, FUL, ADPG1, NST1/3 and IND were associated with shattering in B. juncea and B. napus. We noted a correlation between reduced pectin degradation genes and shatter-resistance. Tension between lignified and non-lignified cells in the silique DZ plays a major role in dehiscence. Light microscopy revealed a smaller non-lignified separation layer in relatively shatter-resistant B. juncea relative to B. napus and this corresponded to increased expression of peroxidases involved in monolignol polymerization. Sustained repression of auxin biosynthesis, transport and signaling in B. juncea relative to B. napus may cause differences in dehiscence zone structure and cell wall constituents. Tension on the dehiscence zone is a consequence of shrinkage and loss of flexibility in the valves, which is caused by senescence and desiccation. Reduced shattering was generally associated with upregulation of ABA signaling and down-regulation of ethylene and jasmonate signaling, corresponding to more pronounced stress responses and reduced senescence and photosynthesis. Overall, we identified 124 cell wall related genes and 103 transcription factors potentially involved in silique dehiscence. PMID:25523176

    Wound infection in the setting of immunosuppressed state such as renal transplantation (RT) causes significant morbidity from sepsis, prolongs hospital stay and is expensive. Vacuum-assisted closure (VAC) therapy is a new technique of management of wound based on the principle of application of controlled negative pressure. The aim of this study was to assess the efficacy of VAC therapy in the management of wound infection following RT. This is a prospective study of a cohort of 180 consecutive RTs performed over a period of 4 years, where the data were retrieved from a prospectively maintained computerised database and case-notes. 9 of 180 (5%) patients developed wound infection following RT which led to cavitations and dehiscence with copious discharge, and refused to heal with conventional treatment. All 9 cases were treated with VAC therapy. The VAC system was removed after a median of 9 (range 3-30) days when discharge from the wound ceased. Four patients were discharged home with portable VAC device and managed on an outpatient basis, where the system was removed after a median 5.5 (range 3-7) days. The median hospital stay after initiation of VAC therapy was significantly shorter (5, range 2-12 days) than on conventional treatment prior to VAC therapy (11, range, 5-20 days) (p=0.003). Complete healing was achieved in all cases. The use of VAC therapy is an effective and safe adjunct to conventional and established treatment modalities for the management of wound infection and dehiscence following RT. Key words: Renal transplantation, wound infection, vacuum-assisted closure therapy.

    The majority of war wounds are caused by antipersonnel fragments from munitions such as mortars and bomblets. Modern munitions aim to incapacitate soldiers with multiple wounds from very small fragments of low available kinetic energy. Many of these fragments may be stopped by helmets and body armour and this has led to a predominance of multiple wounds to limbs in those casualties requiring surgery. The development of an appropriate management strategy for these multiple wounds requires knowledge of the contamination and extent of soft tissue injury; conservative management may be appropriate. The extent of skin and muscle damage associated with a small fragment wound, the way in which these wounds may progress without intervention and their colonisation by bacteria has been determined in an experimental animal model. Results from 12 animals are presented. There was a very small (approximately 1 mm) margin of nonviable skin around the entrance wound. The amount of devitalised muscle in the wound tract was a few hundred milligrams. Some muscles peripheral to the wound track also showed signs of damage 1 h after wounding, but this improved over 24 h; the proportion of fragmented muscle fibres in the tissue around the track decreased as time went on. There was no clinical sign or bacteriological evidence of the track becoming infected up to 24 h after wounding. This preliminary work suggests that, in the absence of infection, the amount of muscle damage caused by small fragment wounds begins to resolve in the first 24 h after injury, even without surgical intervention.

    Full Text Available Postoperative wound infection in an instrumented spine patient is often disastrous. Management includes implant removal leading to spine instability. Negative pressure wound therapy (NPWT applied to the spine surgical wound is one of the wound care technique with successful results. We report a case of a man who sustained Chance fracture of Lumbar 1 (L1 vertebra treated with long segment posterior instrumentation, who unfortunately developed Extended-spectrum beta-lactamase (ESBL positive E. coli infection one month after the operation. After careful debridement of the wound, the implant became exposed. Three cycles of NPWT were applied and the wound healed with granulation tissue completely covering the implant, and thus negating the need to remove the implant. In conclusion, the NPWT is a good alternative in postoperative wound management especially in an instrumented spine patient.

    Full Text Available OBJECTIVE: to evaluate the return to sport after surgical treatment for pubalgia among 30 professional soccer players and describe the surgical technique used.METHOD: this case series was evaluated by means of a questionnaire and physical examination on 30 male professional soccer players of mean age 24.4 years (range: 18-30. The mean duration of the symptoms was 18.6 months (range: 13-28. The diagnosis was made through clinical investigation, special maneuvers and complementary examinations, by the same examiner. All the patients underwent surgical treatment after conservative treatment failed; all procedures were performed by the same surgeon using the same technique. Nonparametric comparisons were made to investigate the time taken to recover after the surgery, for the patients to return to their sport.RESULTS: five patients evolved with hematoma, with the need to remove the stitches three weeks after the operation because of a small dehiscence at the site of the operative wound. The wound healed completely in all these cases by five weeks after the surgery. Four patients presented dysuria in the first week, but improved in the second postoperative week. The mean time taken to return to training was around eight weeks (range: seven-nine. All the players returned to competitive soccer practice within 16 weeks. When asked about their degree of satisfaction after the operation (satisfied or dissatisfied, taking into consideration their return to the sport, there was 100% satisfaction, and they returned to professional practice at the same competitive level as before the injury. This degree of satisfaction continued to the last assessment, which was made after 36 months of postoperative follow-up.CONCLUSION: the surgical technique presented in this case series, with trapezoidal resection of the pubic symphysis in association with bilateral partial tenotomy of the long adductor, was a fast and effective procedure with a low rate of postoperative

    Objective to evaluate the return to sport after surgical treatment for pubalgia among 30 professional soccer players and describe the surgical technique used. Method this case series was evaluated by means of a questionnaire and physical examination on 30 male professional soccer players of mean age 24.4 years (range: 18–30). The mean duration of the symptoms was 18.6 months (range: 13–28). The diagnosis was made through clinical investigation, special maneuvers and complementary examinations, by the same examiner. All the patients underwent surgical treatment after conservative treatment failed; all procedures were performed by the same surgeon using the same technique. Nonparametric comparisons were made to investigate the time taken to recover after the surgery, for the patients to return to their sport. Results five patients evolved with hematoma, with the need to remove the stitches three weeks after the operation because of a small dehiscence at the site of the operative wound. The wound healed completely in all these cases by five weeks after the surgery. Four patients presented dysuria in the first week, but improved in the second postoperative week. The mean time taken to return to training was around eight weeks (range: seven–nine). All the players returned to competitive soccer practice within 16 weeks. When asked about their degree of satisfaction after the operation (satisfied or dissatisfied), taking into consideration their return to the sport, there was 100% satisfaction, and they returned to professional practice at the same competitive level as before the injury. This degree of satisfaction continued to the last assessment, which was made after 36 months of postoperative follow-up. Conclusion the surgical technique presented in this case series, with trapezoidal resection of the pubic symphysis in association with bilateral partial tenotomy of the long adductor, was a fast and effective procedure with a low rate of postoperative

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

    Improvement of the healing process to provide better aesthetical and functional results continues to be a surgical challenge. This study compared the treatment of skin wounds by means of conducted healing (an original method of treatment by secondary healing) and by the use of autogenous skin grafts. Two skin segments, one on each side of the dorsum,were removed from 17 rabbits. The side that served as a graft donor site was left open as to undergo conducted healing (A)and was submitted only to debridement and local care with dressings. The skin removed from the side mentioned above was implanted as a graft (B) to cover the wound on the other side. Thus, each animal received the two types of treatment on its dorsum (A and B). The rabbits were divided into two groups according to the size of the wounds: Group 1 - A and B (4 cm2)and Group 2 - A and B (25 cm2). The healing time was 19 days for Group 1 and 35 days for Group 2. The final macro- and microscopic aspects of the healing process were analysed comparatively among all subgroups. The presence of inflammatory cells, epidermal cysts and of giant cells was evaluated. No macro- or microscopic differences were observed while comparing the wounds that underwent conducted healing and those in which grafting was employed, although the wounds submitted to conducted healing healed more rapidly. Conducted wound healing was effective for the treatment of skin wounds. Celsius.

    To study the effect of hyperthermia on the inhibition of healing by radiation, the authors used 2 models of wound tensile strength in mice. In one, tensile strength of 1 cm strips of wounded skin was measured. In the other, strength was measured on 2 by 1 by .3 cm surgical prosthetic sponges of polyvinyl alcohol which has been cut, resutured, and implanted subcutaneously. Granulation tissue grows into the pores of the sponges which gradually fill with collagen. Tensile strength in both models was measured on day 14 using a constant strain extensiometer. The wounds were given graduated doses of ortho-voltage radiation with or without hyperthermia. Maximum radiation sensitivity occurred during the period of rapid neovascularization in the first 5 days after wounding, when a loss of 80% in wound strength occurred with doses less than 20 gray. For single radiation doses given 48 hours after wounding, the authors found a steep dose-response curve with half maximum reduction in strength occurring in both models at approximately 10 gray. Hyperthermia was produced in two ways. Skin wounds were heated in a circulating water bath. In the sponge model, more uniform heating occurs with an RF generator scaled to the mouse. At a dose of 43 C for 30 minutes, no inhibition of healing by heat alone was found. However the combination of heat and radiation produced definite enhancement of radiation damage, with thermal enhancement ratios of up to 1.9 being observed

    In colorectal cancer surgery, surgical site infection (SSI) is a common complication, and especially, perineal wound complications after abdominoperineal resection (APR) remain to be serious clinical problems. Vacuum-assisted closure (VAC) therapy was first reported in another surgical field in 1997, and it is useful for treating complex wounds because it promotes granulation. VAC therapy has been recently used for open abdominal wounds. We introduced VAC for treating open perineal wound of APR and report the usefulness of it. We treated four patients. Firstly, in cases 1 and 2, we introduced VAC therapy to the management of SSI of the perineal wound after APR, and it was useful to control postoperative perineal wound infection. And also, in cases 3 and 4, we introduced VAC therapy to prevent perineal wound infection. Perineal wound infection did not happen. A vertical rectus abdominis myocutaneous flap has been reported to decrease perineal wound complications including pelvic abscess and open perineal wound; however it results in significant operative blood loss, increased operative time, and additional surgical complications. In our cases, there were no complications relating to VAC therapy and it promoted rapid wound healing. Our results suggested that it is an effective treatment for APR in a high-risk case of an open perineal wound. VAC therapy is a less invasive method and a useful treatment for open perineal wound of APR. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

  2. Vaginal Cuff Dehiscence Presenting with Free Air 60 Days after Robotic-Assisted Hysterectomy

    Full Text Available Introduction. The vast majority of patients presenting with pneumoperitoneum have visceral organ perforation and require urgent diagnostic laparoscopy. Nonsurgical causes are relatively rare and may be attributed to multiple etiologies. Case Presentation. Here we describe the case of a 38-year-old Caucasian female who presented to the emergency department with three days of cramping, epigastric abdominal pain. Her physical exam was notable for tenderness to palpation in the epigastric area and abdominal and chest X-rays showed free air under the diaphragm. Free air around the porta hepatis was verified on CT scan. Approximately 90% of pneumoperitoneum cases are due to perforation of visceral organs and therefore require operative management. An urgent exploratory laparoscopy revealed no clear source of free air, but postoperatively the patient developed a large volume of watery discharge from her vagina. Subsequent workup revealed a 1 cm vaginal cuff dehiscence which was later repaired with no postoperative complications. Conclusion. Although the majority of patients with pneumoperitoneum require urgent exploratory laparoscopy, a careful diagnostic workup may reveal sources of free air that are not related to hollow viscous perforation. Vaginal cuff dehiscence represents a rare yet nonurgent source of pneumoperitoneum. This differential should be considered in light of the possible intra- and postoperative complications of surgery.

  3. Exploding a myth: the capsule dehiscence mechanism and the function of pseudostomata in Sphagnum.

    The nineteenth century air-gun explanation for explosive spore discharge in Sphagnum has never been tested experimentally. Similarly, the function of the numerous stomata ubiquitous in the capsule walls has never been investigated. Both intact and pricked Sphagnum capsules, that were allowed to dry out, all dehisced over an 8-12 h period during which time the stomatal guard cells gradually collapsed and their potassium content, measured by X-ray microanalysis in a cryoscanning electron microscope, gradually increased. By contrast, guard cell potassium fell in water-stressed Arabidopsis. The pricking experiments demonstrate that the air-gun notion for explosive spore discharge in Sphagnum is inaccurate; differential shrinkage of the capsule walls causes popping off the rigid operculum. The absence of evidence for a potassium-regulating mechanism in the stomatal guard cells and their gradual collapse before spore discharge indicates that their sole role is facilitation of sporophyte desiccation that ultimately leads to capsule dehiscence. Our novel functional data on Sphagnum, when considered in relation to bryophyte phylogeny, suggest the possibility that stomata first appeared in land plants as structures that facilitated sporophyte drying out before spore discharge and only subsequently acquired their role in the regulation of gaseous exchange.

    The objectives of this study were to evaluate blood and abdominal fluid lactate and glucose, fluid cytology, culture, and volume 24 and 48 hr following intestinal resection and anastomosis in dogs with and without closed-suction drains and to correlate findings with survival. Thirty-five client-owned dogs that underwent intestinal resection and anastomosis were prospectively enrolled in the study. Abdominal fluid was submitted for culture at surgery and again 24 hr postoperatively. Twenty-four and 48 hr postoperatively, blood and abdominal fluid glucose and lactate were measured and fluid was submitted for cytology. Abdominal fluid was collected either from a closed-suction drain or by abdominocentesis. Patients were followed either for 14 days or until death. Comparisons were made based on development of dehiscence and presence or absence of a drain. Patients with dehiscence were more likely to have positive cultures at 24 hr and to have had more bowel resected. Surviving patients without drains had significantly smaller differences in blood and fluid glucose and lactate both 24 and 48 hr postoperatively than surviving patients with drains. The significant differences identified between patients with and without drains suggests a need for further research into the effect of drains on abdominal fluid values.

    To evaluate bone reconstruction and soft tissue reactions at immediate implants placed into intact sockets and those with buccal bone dehiscence defects. Fifty-nine internal connection implants from four different manufacturers were immediately placed in intact sockets(non-dehiscence group, n=40), and in alveoli with buccal bone dehiscence defects: 1) Group 1(n= N10), the defect depth measured 3-5 mm from the gingival margin. 2) Group 2(n=9), the depth ranged from 5mm to 7mm. The surrounding bony voids were grafted with deproteinized bovine bone mineral (DBBM) particles. Cone beam computed tomography(CBCT) was performed immediately after surgery (T1), and at 6 months later(T2). Radiographs were taken at prosthesis placement and one year postloading(T3). Soft tissue parameters were measured at baseline (T0), prosthesis placement and T3. No implants were lost during the observation period. For the dehiscence groups, the buccal bone plates were radiographically reconstructed to comparable horizontal and vertical bone volumes compared with the non-dehiscence group. Marginal bone loss occurred between the time of final restoration and 1-year postloading was not statistically different(P=0.732) between groups. Soft tissue parameters did not reveal inferior results for the dehiscence groups. Within the limitations of this study, flapless implant placement into compromised sockets in combination with DBBM grafting may be a viable technique to reconstitute the defected buccal bone plates due to space maintenance and primary socket closure provided by healing abutments and bone grafts. Immediate implants and DBBM grafting without using membranes may be indicated for sockets with buccal bone defects. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The pulmonary and cardiovascular ramifications of smoking are well documented and this also applies to increased wound healing complications in smokers. The aim of this study was to ascertain whether preoperatively refraining from smoking would affect the incidence of wound healing disorders. Between 2006 and 2008 a total of 295 patients underwent aesthetic (n = 167) or reconstructive surgery (n = 128). They were divided into three groups: A (n = 98) non-smokers for at least 2 years, B (n = 99) patients who refrained from smoking 6 weeks prior to surgery and C (n = 98) smokers. Smoking abstinence was verified by cotinine tests. Wound healing complications were defined as dehiscent wounds, wound infections, atypical scar formation and adiponecrosis. Smokers developed wound healing complications in 48.2% of cases, non-smokers in 21.0% and patients who had stopped smoking for 6 weeks in 30.8% of cases (p = 0.006). Elective surgery should only be performed on non-smokers and smokers who had refrained from smoking for at least 6 weeks to reduce wound healing complications as far as possible.

    Wound healing is considered to be particularly important after surgical procedures, and the most important wounds related to surgical procedures are incisional, excisional, and punch wounds. Research is ongoing to identify methods to heal non-closed wounds or to accelerate wound healing; however, wound healing is a complex process that includes many biological and physiological events, and it is affected by various local and systemic factors, including diabetes mellitus, infection, ischemia, and aging. Different cell types (such as platelets, macrophages, and neutrophils) release growth factors during the healing process, and platelet-derived growth factor is a particularly important mediator in most stages of wound healing. This review explores the relationship between platelet-derived growth factor and wound healing. © 2014 The International Society of Dermatology.

    Intramuscular ketorolac is a commonly used nonsteroidal anti-inflammatory (NSAI) agent for analgesia in surgical patients. Increasing numbers of surgical patients are chronically taking some form of an NSAI drug. We examined the effects of "chronic" intramuscular ketorolac on the healing of a closed linear surgical wound in the rat. Wistar rats were pretreated with 4 mg per kilogram per day ketorolac intramuscularly prior to receiving dorsal incisional wounds. The ketorolac treatment was continued and after 2 weeks the wounds were excised and separated with a tensiometer to measure mechanical properties. Breaking strength was directly measured, tensile strength was calculated, and collagen concentrations at the wound site were determined. A significant decrease in the mean breaking strength was seen in the ketorolac-treated animals when compared to controls. The ketorolac-treated animals had a mean tensile strength less than the controls, although this difference did not reach statistical significance. The mean collagen concentration of the ketorolac-treated wounds was significantly less than the untreated wounds. Use of ketorolac for just 1 week prior to surgery in rats produced a significant decrease in the breaking strength of their wounds. With the increasing use of ketorolac in surgical patients as well as the increasing use of oral NSAI drugs, more study of this effect is warranted.

    Some experiences in medical treatment of plutonium-contaminated wound gained through the animal experiments and clinical practices were described. For the treatment of plutonium-contaminated wound, much attention should be devoted to the early emergency measure at accident site. In some case when the surgical interference is needed, radioactivity in local wound and in regional lympho-nodes of wound, firstly, must be determined and the contaminated area must be demonstrated before operation. Selecting a proper approach for anaesthesia is one of the critical factors for successfulness of operation. The operation should be performed under the coordination of monitoring workers. During operation, the rules for decontamination should be followed to avoid recontamination. In addition to conventional administration of chelating agents, the local application of such agents during and after operation is a better supplementary therapeutic procedure for some cases when the residual amount of plutonium in wound is less and any other surgical procedures will not be performed further

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

    For intensive care unit (ICU) patients with gastrointestinal dysfunction and in need of total parenteral nutrition (TPN) support, the benefit of additional enteral feeding is not clear. This study aimed to investigate whether combined TPN with enteral feeding is associated with better outcomes in surgical intensive care unit (SICU) patients. Clinical data of 88 patients in SICU were retrospectively collected. Variables used for analysis included route and percentage of nutritional support, total caloric intake, age, gender, body weight, body mass index, admission diagnosis, surgical procedure, Acute Physiology and Chronic Health Evaluation (APACHE) II score, comorbidities, length of hospital stay, postoperative complications, blood glucose values and hospital mortality. Wound dehiscence and central catheter infection were observed more frequently in the group of patients receiving TPN calories less than 90% of total calorie intake (p = 0.004 and 0.043, respectively). APACHE II scores were higher in nonsurvivors than in survivors (p = 0.001). More nonsurvivors received TPN calories exceeding 90% of total calorie intake and were in need of dialysis during ICU admission (p = 0.005 and 0.013, respectively). Multivariate analysis revealed that the percentage of TPN calories over total calories and APACHE II scores were independent predictors of ICU mortality in patients receiving supplementary TPN after surgery. In SICU patients receiving TPN, patients who could be fed enterally more than 10% of total calories had better clinical outcomes than patients receiving less than 10% of total calorie intake from enteral feeding. Enteral feeding should be given whenever possible in severely ill patients. 2012 Published by Elsevier B.V

    Surgical therapy of perineal hernia in dogs by using Small Intestinal Submucosa (SIS™). Retrospective evaluation of pre-, intra-, and postoperative data of 15 dogs for which a total of 21 perineal hernias were surgically treated by implantation of SIS™ between July 2003 to January 2005 at the Hospital for Small Animals, Surgery, Justus Liebig University of Giessen. Eleven of the 15 dogs showed a large sized perineal hernia, whereas in four dogs the defect was of medium size. Preoperatively, 86.7% of the patients showed defecation problems and 40% had perineal swelling. Retroflexion of the bladder was observed in four dogs. Average operation time was 58.1 minutes (50-70 minutes). No intraoperative complications were observed. Postoperative complications were minor (seroma formation in six patients, minor wound dehiscence in three dogs), and only three cases required local therapy. Implant intolerance was not observed. Long-term results were obtained 6-36 months postoperatively (mean 25.2 months) by rectal examination and owner telephone questionnaire. The recurrence rate, based on clinical signs of perineal hernia, was 9.5% (two of 21 perineal hernias). Results were rated excellent to good in 19 of the 21 surgically treated perineal hernias. Implantation of SIS™ in the treatment of perineal hernia in dogs is an easy and safe treatment option. Long-term implant tolerance appears to be excellent. Recurrence rate of clinical signs is low. In cases where the defect can not be closed with endogenous tissue, either due to atrophic tissue or dimensions of perineal hernia do not allow such closure, the use of Small Intestinal Submucosa should be considered. The additional costs for the implant are however a disadvantage of this method.

    Full Text Available PURPOSE: To evaluate the inflammatory response of potentially infected wounds treated with isotonic saline solution, chlorhexidine and PVP-I, seven days after surgery. METHODS: Thirty-two male rats were used, divided into 4 groups. All animals had their surgical wounds infected with a standard bacterial inoculum. Control group (A: animals had their surgical wounds sutured without any kind of cleaning. Saline solution group (B: animals had their wounds cleaned with saline solution. Chlorhexidine group (C: animals had their wounds cleaned with chlorhexidine. PVP-I group (D: animals had their wounds cleaned with PVP-I. Seven days after surgery, all the animals had their skin submitted to microscopic and macroscopic evaluation. RESULTS: Edema was found on all histological slices analyzed, as well as vascular proliferation and congestion. Groups A and D showed presence of mild neutrophilic infiltrate, and moderate lymphocytic and macrophage infiltrate. Group B showed severe neutrophilic, macrophage, and lymphocytic infiltrate. Group C showed moderate neutrophilic, macrophage, and lymphocytic infiltrate. CONCLUSION: Group D was the group which showed inflammatory infiltrate most similar to the group that was not submitted to treatment.

    Renal impairment has long been known to affect wound healing. However, information on differences in the spectrum of wound healing depending on the type of renal insufficiency is limited. Acute kidney injury (AKI) may be observed with different wound types. On one hand, it follows acute traumatic conditions such as crush injury, burns, and post-surgical wounds, and on the other hand, it arises as simultaneous targeting of skin and kidneys by autoimmune-mediated vasculitis. Chronic kidney disease (CKD) and end-stage renal disease (ESRD) often occur in older people, who have limited physical mobility and predisposition for developing pressure-related wounds. The common risk factors for poor wound healing, generally observed in patients with CKD and ESRD, include poorly controlled diabetes mellitus, neuropathy, peripheral vascular disease, chronic venous insufficiency, and aging. ESRD patients have a unique spectrum of wounds related to impaired calcium-phosphorus metabolism, including calciphylaxis, in addition to having the risk factors presented by CKD patients. Overall, there is a wide range of uremic toxins: they may affect local mechanisms of wound healing and also adversely affect the functioning of multiple systems. In the present literature review, we discuss the association between different types of renal impairments and their effects on wound healing and examine this association from different aspects related to the management of wounds in renal impairment patients.

    Ocular imaging can enhance our understanding of wound healing. We report anterior segment optical coherence tomography (ASOCT) findings in penetrating corneal injury. Serial ASOCT was performed after repair of penetrating corneal injury. Internal aberrations of wound edges were labeled as "steps" or "gaps" on ASOCT images. The wound type was characterized as: type 1: continuous inner wound edge or step height ≤ 80 µm; type 2: step height > 80 µm; type 3: gap between wound edges; and type 4: intraocular tissue adherent to wound. Surgical outcomes of different wound types were compared. 50 consecutive patients were included (6 females, 44 males; mean age 33 ± 12 years). The average size of wound was 4.2 ± 2.6 mm (type 1, 8 eyes; type 2, 27 eyes; type 3, 12 eyes; type 4, 3 eyes). At the end of 3 months, 70% (n = 35) of the wounds were type 1. At the end of 6 months, all type 1 wounds had healed completely, whereas about half of type 2 (48.1%) and type 3 (50%) wounds had recovered to type 1 configuration. The wound type at baseline affected the height of step (p = 0.047) and corneal thickness at 6 months (p = 0.035). ASOCT is a useful tool for monitoring wound healing in cases with penetrating corneal injury. Majority of the wound edges appose between 3 and 6 months after trauma. In our study, baseline wound configuration affected the healing pattern.

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

    As we have emphasized, the diagnosis of burn wound infections in the high-risk burned child can be difficult and depends on a very high degree of suspicion and daily clinical evaluation of the burn wound site by consistent observers. Appropriate precautions include meticulous hand-washing and the use of gloves when handling the wound site and prophylactic application of a topical antibacterial agent such as SSD cream. Wound therapy should include routine vigorous surgical débridement. Surveillance wound cultures should be done weekly to determine the emergency of colonization and aid in the selection of empiric antimicrobial regimens when these are appropriate. Wound biopsy for histological examination and quantitative culture is highly recommended in the severely ill child with an unclear etiology or site of infection. If, despite these measures, sepsis ensues, then systemic antibiotics must be started empirically as an adjuctive therapy to surgical débridement. Knowledge of the organisms colonizing a wound will prove useful in choosing an antibiotic regimen while awaiting definitive results of blood and wound biopsy cultures. Without this information, early burn sepsis therapy should focus on gram-positive organisms, while infection later in the course should raise suspicion of nosocomial pathogens such as P. aeruginosa, other enteric bacilli, and C. albicans. An initial regimen might include nafcillin plus ceftazidime or an aminoglycoside, with anaerobic coverage depending on considerations noted previously. Once the causative agent is identified, therapy must be modified accordingly. Amphotericin B and acyclovir use should be guided by positive cultures from the burn wound site along with systemic evidence of dissemination. Available studies do not yet make clear the role of empiric immunotherapy with intravenous gamma globulin in the burned child. Therefore, its use cannot be recommended at the present time, although the development of specific

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

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

    Chronic ulcers have adverse effects on the patient quality of life and productivity, thus posing financial burden upon the healthcare system. Chronic wound healing is a complex process resulting from the interaction of the patient general health status, wound related factors, medical personnel skill and competence, and therapy related products. In clinical practice, considerable improvement has been made in the treatment of chronic wounds, which is evident in the reduced rate of the severe forms of chronic wounds in outpatient clinics. However, in spite of all the modern approaches, efforts invested by medical personnel and agents available for wound care, numerous problems are still encountered in daily practice. Most frequently, the problems arise from inappropriate education, of young personnel in particular, absence of multidisciplinary approach, and inadequate communication among the personnel directly involved in wound treatment. To perceive them more clearly, the potential problems or complications in the management of chronic wounds can be classified into the following groups: problems mostly related to the use of wound coverage and other etiology related specificities of wound treatment; problems related to incompatibility of the agents used in wound treatment; and problems arising from failure to ensure aseptic and antiseptic performance conditions.

    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

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

    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.

    2012-10-01

    Debridement is the process of removing dead tissue from the wound bed. Since devitalized tissue can obstruct or completely stop healing of the wound, it is indicated to debride wound bed as part of the treatment process. The aim of debridement is to transform a chronic wound into an acute wound and to initiate the process of healing. Debridement is the foundation of each wound treatment and it has to be repeated, depending on the necrotic tissue formation. There are several types of debridement: surgical, autolytic, chemical, enzymatic, mechanical, and biological. Using previous knowledge and advances in technology, new types of debridement have been introduced. Besides standard methods, methods of pulsed lavage debridement (hydro-surgery, water-jet) and ultrasound-assisted wound treatment (UAW) are ever more widely introduced. The method of debridement the clinician will choose depends on the amount of necrotic (devitalized) tissue in the wound bed, the size and depth of the wound, the underlying disease, the possible comorbidity, as well as on the general condition of the patient. Frequently, the methods of debridement are combined in order to achieve better removal of devitalized tissue. Debridement in addition significantly reduces bacterial burden. Regardless of the method of debridement, it is essential to take pain to the lowest point.

    A worker noted a small wound to his thumb when leaving a work site that was undergoing decontamination because of past operations with plutonium (Pu) and americium (Am). Direct surveys of the wound site confirmed the presence of contamination. The chelating agent Ca-DTPA was administered via a nebulizer within an hour after discovery of the wound. External measurements were made of the wound site and wound dressings; 24-h urinary excretion data were collected periodically and the Pu and Am urine content was determined. Zn-DTPA was administered on three occasions. The ICRP Pu systemic model was modified to consider the enhanced urinary excretion following administration of the chelating agents. The analysis indicated that the wound resulted in an initial deposition of 400 Bq 238 Pu, 2240 Bq 239 / 240 Pu and 1060 Bq 241 Am. About 70% of the initial wound activity was removed by surgical procedures and less than 1% of the wound activity was removed by chelation therapy. This paper compares the observed urinary excretion data with that indicated by a simulation of the kinetics of the transfer from the wound site and the kinetics of the chelating agent and Pu.

    Full Text Available Traumas of the foetus caused by stabbings are rare but actually life-threatening for both the foetus and the mother. We report a case of penetrating chest wound on a baby taken from the obstetrics unit to the paediatric surgical department. His mother was assaulted by his father, a mentally sick person with no appropriate follow-up. The foetus did not show any sign of vital distress. Surgical exploration of the wound has revealed a section of the 10 th rib, a laceration of the pleura and a tearing of the diaphragm. A phrenorraphy and a pleural drainage were performed. The new-born and its mother were released from hospital after 5 days and the clinical control and X-ray checks 6 months later showed nothing abnormal. We insisted a medical, psychiatric follow-up be initiated for the father. As regards pregnant women with penetrating wounds, the mortality rate of the foetus is 80%. The odds are good for our newborn due to the mild injuries and good professional collaboration of the medical staff. Penetrating transuterine wounds of the foetus can be very serious. The health care needed should include many fields due to the mother and the foetus′ lesions extreme polymorphism. In our case, it could have prevented by a good psychiatric followed up of the offender.

    Topical negative pressure (TNP) therapy is widely used in the treatment of acute wounds in vascular patients on the basis of proposed multifactorial benefits. However, numerous recent systematic reviews have concluded that there is inadequate evidence to support its benefits at a scientific level. This study evaluated the changes in wound volume, surface area, depth, collagen deposition, and tissue oxygenation when using TNP therapy compared with traditional dressings in patients with acute high-risk foot wounds. This study was performed with hospitalized vascular patients. Forty-eight patients were selected with an acute lower extremity wound after surgical débridement or minor amputation that had an adequate blood supply without requiring further surgical revascularization and were deemed suitable for TNP therapy. The 22 patients who completed the study were randomly allocated to a treatment group receiving TNP or to a control group receiving regular topical dressings. Wound volume and wound oxygenation were analyzed using a modern stereophotographic wound measurement system and a hyperspectral transcutaneous oxygenation measurement system, respectively. Laboratory analysis was conducted on wound biopsy samples to determine hydroxyproline levels, a surrogate marker to collagen. Differences in clinical or demographic characteristics or in the location of the foot wounds were not significant between the two groups. All patients, with the exception of two, had diabetes. The two patients who did not have diabetes had end-stage renal failure. There was no significance in the primary outcome of wound volume reduction between TNP and control patients on day 14 (44.2% and 20.9%, respectively; P = .15). Analyses of secondary outcomes showed a significant result of better healing rates in the TNP group by demonstrating a reduction in maximum wound depth at day 14 (36.0% TNP vs 17.6% control; P = .03). No significant findings were found for the other outcomes of changes

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

    Irradiation of normal tissues at the dose/time factor employed in the treatment of solid tumors impairs the subsequent healing of surgical wounds made in those tissues. Irreversible radiation damage to regional fibroblasts is one cause of impared healing. This study was conducted to determine whether syngeneic guinea pig fibroblasts is one cause of impared healing. This study was conducted to determine whether syngeneic guinea pig fibroblasts, harvested from tissue culture when injected into irradiated guinea pig skin at the time of wound closure, could improve wound healing. Breaking strength determinations indicate that irradiated wounds demonstrate enhanced wound healing if implanted with fibroblasts.

    Full Text Available Enteric perforation is a serious complication of typhoid fever. Depending upon the bowel condition, primary closure of perforation is the treatment of choice. Development of fecal fistula is the key apprehension in primary closure. The purpose of this study is to find out the benefit of an omental patch when used over primary closure. It is a small study of 60 patients, which were divided into two groups: Group I - Primary closure with omental patch, and Group II - only primary closure. The outcomes were measured in relation to wound infection, fecal fistula, wound dehiscence, and intra-abdominal abscess. The incidence of complications including fecal fistula and mortality is significantly lower in the group-I patients. Fecal fistula occurs in 13.33% in group II, while in only 3.3% in group I. There was no significant difference in the incidence of wound infection and wound dehiscence. Primary closure with an omental patch is a better option compared with only primary closure in enteric perforation patients. It can be suggested as an alternative method to primary closure only in selective enteric perforation patients. [Arch Clin Exp Surg 2013; 2(2.000: 80-84

    Full Text Available OBJECTIVE: To demonstrate the main aspects of diagnosis, treatment and follow-up of 43 patients with gunshot wounds to the penis. MATERIALS AND METHODS: The location of the lesion, the presence of associated lesions, the performance of complementary exams, surgical treatment, postoperative complications and long term follow-up of 43 patients with penile lesions from gunshot wounds were retrospectively analyzed. RESULTS: Of 43 cases assessed, 41 were submitted to surgical exploration (95.3% and 2 were submitted to conservative treatment (4.7%. We found penile lesions involving the corpus cavernosum in 37 cases; the remaining 4 patients presented no lesions involving the corpus cavernosum, urethra or testicles but did in the superficial structures. Ten cases presented an association with testicular lesions and 14 cases association with anterior urethral lesions. CONCLUSION: Penile lesions from gunshot wounds should be treated with immediate surgical intervention. In exceptional situations featuring superficial lesions only conservative treatment may be applied.

    Full Text Available Com o objetivo de avaliar e comparar clínica e histologicamente o uso do adesivo metil-2-cianoacrilato e do fio de náilon na reparação de feridas cirúrgicas de pele, foram utilizados cinco cães e cinco gatos adultos, clinicamente sadios. Seguindo o protocolo anestésico e cirúrgico habitual para cada espécie, foram feitas cinco incisões na pele da região costal do lado esquerdo e cinco do lado direito, com aproximadamente dois centímetros de comprimento. As feridas cirúrgicas do lado direito foram suturadas com fio de náilon cirúrgico 3-0 e as do lado esquerdo foram aproximadas e fixadas com o metil-2-cianoacrilato em ambas as espécies. Os animais foram submetidos a avaliações clínicas a cada três dias. Foram retirados fragmentos de pele para realização de biopsias aos três, seis, nove, doze e quinze dias após a cirurgia. Os resultados obtidos, tanto em cães quanto em gatos, não revelaram diferença clínica ou histológica entre os tratamentos utilizados.The purpose of this study is to evaluate and compare clinically and histologically the use of methyl-2-cyanoacrylate adhesive versus the nylon's suture in skin wounds closure. There were five adult mongrel dogs and cats, clinically healthy used. Following anaesthetical routine and surgical protocol, five incisions were made in the left costal region, and other five in right costal region, about 2cm in length, in both especies. The right side costal wounds were sutured with surgical nylon 3-0, and in the left side costal wounds methyl-2-cyanoacrylate was applied, in both species. The animals were submitted to clinical evaluation every three days, and a biopsy was realized at three, six, nine, twelve and fifteen days after the surgery. In both species, the results did not show any clinical or histologic difference when comparing the used treatments.

    Radiation therapy is a major therapeutic modality in the management of cancer patients. Over 60% of these patients receive radiotherapy at some point during their course of treatment and over 90% will develop skin reactions after therapy. Problematic wound healing in radiation-damaged tissue constitutes a major surgical difficulty and despite all efforts, irradiated skin remains a therapeutic challenge. This review provides an overview of the fundamental principles of radiation therapy with regards to the wound healing in normal and irradiated skin. Furthermore, it presents techniques that describe how to prevent and manage skin side effects as well as prospects that may improve cutaneous wound repair in general and in irradiated skin.

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

    Aim: To examine the association between superior semicircular canal dehiscence (SSCD) and pulsatile tinnitus (PT). Materials and methods: Two SSCD groups included 408 unilateral persistent PT patients, and 511 controls undergoing head and neck dual-phase contrast-enhanced computed tomography (DP-CECT) for reasons other than PT. The prevalence of type I (no the superior petrosal sinus running through the dehiscence) and type II (superior semicircular canal dehiscence in relation to the superior petrosal sinus) SSCD was analysed using chi-square test. Results: SSCD was identified in 5.1% (21/408) of PT ears, significantly different from 2% (8/408) of non-PT ears and 0.7% (7/1022) of controls. There was no significant difference in SSCD prevalence between non-PT ears in the PT group and controls. In the PT group, 15/21 ears were type II SSCD; 6/21 ears were type I. Fifteen combined non-PT and control ears with SSCD included two type II and 13 type I SSCD. The prevalence of type II SSCD in PT ears was significantly higher than that of non-PT ears in both groups, and the prevalence of type I SSCD in PT ears was similar to that of non-PT ears in both groups. Conclusion: Compared with type I SSCD, there may be a causal relationship between type II SSCD and PT. -- Highlights: •The prevalence of type II SSCD in PT ears was significantly higher than that in non-PT ears in both the PT group and controls. •The prevalence of type I SSCD was similar among the PT ears and non-PT ears. •The superior petrosal sinus running through the dehiscence may be essential for SSCD to induce PT. •Venous phase CT images with bone window settings is the modality method to differentiate type II from type I SSCD

    Aim: To assess the extent of sigmoid sinus dehiscence (SSD) on high-resolution computed tomography venography (HRCTV) or high-resolution computed tomography (HRCT) images in pulsatile tinnitus (PT) and non-PT groups to determine whether there is an association between the extent of SSD and occurrence of PT. Materials and methods: Twenty-eight SSD patients with ipsilateral PT and 28 age- and gender-matched SSD patients without PT who underwent HRCTV or HRCT were enrolled in this study and categorised into two groups: “PT group” and “non-PT group”. The extent of SSD in each group was calculated and compared. Results: The largest transverse diameter and largest vertical diameter of SSD in the PT group were 6.21±1.7 and 6.15±2.19 mm, respectively. The largest transverse diameter and largest vertical diameter of SSD in the non-PT group were 3.06±1.38 and 2.51±1.03 mm, respectively. The extent of SSD was statistically different between the two groups (p<0.001; p<0.001). Conclusions: As a cause of PT, SSD can also occur in individuals without PT symptoms. Preliminary findings suggest that there may be a potential correlation between the extent of SSD and an occurrence of PT. - Highlights: • We compared the extent of sigmoid sinus dehiscence in pulsatile tinnitus and non-pulsatile tinnitus groups. • The sigmoid sinus dehiscence in the pulsatile tinnitus patients was larger than those in non-pulsatile tinnitus patients. • There may be a potential correlation between the extent of sigmoid sinus dehiscence and an occurrence of pulsatile tinnitus.

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

    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. © 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.

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

    During military conflicts, surviving victims traditionally underwent large enough craniectomy or craniotomy to achieve extensive debridement of the in-driven bone, shell fragments, and debris. Meanwhile, the completely as well as the partially devitalized adjacent brain tissue would also be debrided. This might have led to additional neurologic deficit or lesser degree of recovery of functions. We studied the efficacy and safety of much more limited or even absence of surgical intervention in a selected group of wartime head-wounded patients. Among 1,150 war victims with penetrating head wounds referred to two major centers affiliated with Tehran University of Medical Sciences during the 8-year period spanning the Iran-Iraq conflict, there were 191 head-wounded patients who underwent either no surgical intervention or a very limited debridement. We have attempted to follow up as closely as possible for more than 8 years. Ninety-nine of them fulfilled the criteria to be included in this series. Close follow-up for development of cerebral infections, functional recovery, or development of new neurologic deficits and epilepsy were performed. At least 3 contrast-enhanced CT scans were taken for each patient. All patients were victims of the battle-field areas with low- to moderate-velocity missile or shell fragment injury. The Glasgow Coma Scale (GCS) scores of the patients were between 8-14 when visited by the first attending neurosurgery staff. The factors considered to be effective in the outcome analysis were the entry point, the number of the in-driven bone fragments, the retained shell fragments, the brain compartments affected, and the paranasal sinus or skull base involvement with or without cerebrospinal fluid (CSF) fistula. There were 13 unilobar, 44 bilobar, 4 trilobar, 38 transventricular, and 3 skull base lesions. The number of retained metal fragments varied between 1 to 6. The number of retained bone fragments varied between 1 to 5 in 73 victims and more

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

    Objectives (1) Compare lateral skull base (LSB) height/thickness in patients with spontaneous cerebrospinal fluid otorrhea (CSF), superior canal dehiscence (SCD), acoustic neuromas (AN), and otosclerosis (OTO). (2) Perform correlations between age, body mass index (BMI), sex, and LSB height/thickness. Study Design Case series with chart review. Setting Tertiary referral center. Subjects and Methods Patients with CSF, SCD, AN, and OTO diagnosed from 2006 to 2016 were included if they had high-definition temporal bone computed tomography (CT) and absence of trauma, radiation, chronic ear disease, and/or congenital anomaly. CT-based measurements included LSB height/thickness and pneumatization rates overlaying the external auditory canal (EAC), tegmen tympani (TgT), perigeniculate region (PG), and internal auditory canal (IAC). LSB height/thickness, age, sex, and BMI were statistically correlated. In total, 256 patients and 493 ears (109 CSF, 115 SCD, 269 AN/OTO) were measured. Results Patients with CSF had significantly higher BMIs than the other groups ( P CSF and SCD had similar radiographic LSB phenotypes at most measured locations. Both groups exhibited a significantly lower LSB height compared to the AN and OTO groups (mean, 3.9-4.2 mm vs 4.9-5.6 mm; P CSF and SCD also demonstrated significantly lower pneumatization rates, as low as 17% to 23% overlaying the PG and IAC ( P CSF and SCD exhibit similar radiographic LSB phenotypes. Age, sex, and BMI do not significantly correlate with LSB height/thickness. These data support the theory that CSF and SCD arise via similar congenital pathoetiologic mechanisms.

    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.

    Acute traumatic wounds are contaminated with bacteria and therefore an infection risk. Antiseptic wound irrigation before surgical intervention is routinely performed for contaminated wounds. However, a broad variety of different irrigation solutions are in use. The aim of this retrospective, non-randomised, controlled longitudinal cohort study was to assess the preventive effect of four different irrigation solutions before surgical treatment, on wound infection in traumatic soft tissue wounds. Over a period of three decades, the prophylactic application of wound irrigation was studied in patients with contaminated traumatic wounds requiring surgical treatment, with or without primary wound closure. The main outcome measure was development of wound infection. From 1974-1983, either 0.04 % polihexanide (PHMB), 1 % povidone-iodine (PVP-I), 4 % hydrogen peroxide, or undiluted Ringer's solution were concurrently in use. From 1984-1996, only 0.04 % PHMB or 1 % PVP-I were applied. From 1997, 0.04 % PHMB was used until the end of the study period in 2005. The combined rate for superficial and deep wound infection was 1.7 % in the 0.04 % PHMB group (n=3264), 4.8 % in the 1 % PVP-I group (n=2552), 5.9 % in the Ringer's group (n=645), and 11.7 % in the 4 % hydrogen peroxide group (n=643). Compared with all other treatment arms, PHMB showed the highest efficacy in preventing infection in traumatic soft tissue wounds (p<0.001). However, compared with PVP-I, the difference was only significant for superficial infections. The large patient numbers in this study demonstrated a robust superiority of 0.04 % PHMB to prevent infection in traumatic soft tissue wounds. These retrospective results may further provide important information as the basis for power calculations for the urgently needed prospective clinical trials in the evolving field of wound antisepsis.

    2003-10-01

    Missed diaphragmatic perforation caused by penetrating trauma can lead to subsequent strangulation of a hollow viscus, which has prompted the use of invasive diagnostic procedures to exclude occult diaphragmatic injuries in asymptomatic, high-risk patients. The objective of this study was to determine the incidence of occult diaphragmatic injuries caused by stab wounds of the lower chest and upper abdomen, and to examine the natural history and consequences of missed diaphragmatic injuries. On the basis of patient data from two previous randomized studies from our institution, a retrospective analysis was performed on 97 patients treated for anterior stab wounds located between the nipple line, the umbilical level, and the posterior axillary lines not having indications for immediate surgical exploration. The patients were divided into two groups on the basis of their initial randomized management (open or laparoscopic exploration vs. expectant observation). In the exploration group (n = 47), four diaphragmatic injuries (9%) were detected (three left-sided and one right-sided). Excluding patients with associated injuries requiring surgical repair, the incidence of occult diaphragmatic injuries was 3 of 43 (7%). In the observation group (n = 50), there were two patients (4%) with delayed presentation of missed left-sided diaphragmatic injury 2 and 23 months later, respectively. Both injuries resulted from stab wounds of the left flank and presented with herniation of the stomach or small bowel and colon. The overall incidence of occult diaphragmatic injuries in left-sided thoracoabdominal stab wounds was 4 of 24 (17%), and was much lower after stab wounds of left epigastrium (0%), right lower chest (0%), and right epigastrium (4%). In asymptomatic patients with anterior or flank stab wounds of the lower chest or upper abdominal area, the risk of an occult diaphragmatic injury is approximately 7% which, if undetected, is associated with a high risk of subsequent

    The aim of this study was to evaluate bone regeneration at surgically created dehiscence buccal defects at implants placed immediately into extraction sockets (IPIES) of small dimensions filled with autogenous bone or deproteinized bovine bone mineral (DBBM) associated with a collagen membrane. Eight Labrador dogs were used and implants were placed immediately into the extraction sockets of the second premolar. The buccal wall was subsequently removed to create a standardized defect, 4 mm wide coronally, 2 mm wide apically, and 6 mm high. Autogenous bone particles (AB) or DBBM granules were used to fill the defects. All surgical sites were subsequently covered by a resorbable collagen membrane and a non-submerged healing was allowed. After 4 months, the animals were euthanized and bone blocks harvested and processed for histomorphometric analysis. The bony crest at the buccal aspect (C) was located 2.3 ± 0.8 mm and 1.7 ± 0.7 mm apically to the implant shoulder (IS) at the AB and DBBM sites, respectively. The coronal levels of osseointegration at the buccal aspect (B) were located 2.7 ± 0.7 mm and 2.2 ± 1.0 mm apically to IS at the AB and DBBM sites, respectively. At the AB sites, the peri-implant mucosa was located 4.3 ± 0.9 mm, 4.7 ± 0.9 mm, and 2.0 ± 1.6 mm coronally to C, B, and IS, respectively. The corresponding values at the DBBM sites were 4.3 ± 0.6 mm, 4.8 ± 0.6 mm, and 2.5 ± 0.8 mm, respectively. No statistically significant differences were found. The treatment of surgically created buccal defects at IPIES sites using Bio-Oss® (Geistlich Biomaterials, Wolhusen, LU, Switzerland) or autogenous bone, concomitantly with a collagen membrane, engenders bone regeneration to a similar extent after 4 months of healing. © 2015 Wiley Periodicals, Inc.

    Full Text Available Model experimental studies focused on the intestinal suture techniques in relation to healing, postoperative narrowing of the intestinal lumen or adhesion formation can not comprise a number of clinical factors (foreign body presence in the intestine, haematological abnormalities, septic peritonitis, different age of patients, etc. that under clinical practice conditions may have an effect on the healing of the intestinal suture. The aim of this clinical study was to confirm in a group of dogs surgically treated for small bowel obstruction, whether different techniques of its wall suture may affect the frequency of possible dehiscence occurrence. This study compares two different techniques of intestinal wall suture in relation to postoperative dehiscence of the intestinal wall closure. Based on the clinical observation with regard to the risk of postoperative dehiscence and possible complications in form of adhesions, also the importance of omentalisation in the suture of small bowel was evaluated. No significant difference was demonstrated (p > 0.05 in the frequency of postoperative dehiscence at the site of the intestinal wall closure between the two-layer inverting and singlelayer appositional techniques of suture. Likewise, no significant difference was demonstrated (p > 0.05 in the frequency of dehiscence of intestinal wall suture between patients that underwent intestinal suture omentalisation and those whose intestinal wall suture was not complemented with omentalisation. Based on the results of this clinical study it may be stated that both manual single-layer approximation technique and two-layer inverting technique of the intestinal wall suture are equally safe from the viewpoint of possible dehiscence, and it depends on the surgeon's preference, which one of the said techniques he or she chooses. Concurrently it may be assumed that an exactly performed suture of the intestinal wall does not necessarily require omentalisation.

    The Combat Wound Initiative (CWI) program is a collaborative, multidisciplinary, and interservice public-private partnership that provides personalized, state-of-the-art, and complex wound care via targeted clinical and translational research. The CWI uses a bench-to-bedside approach to translational research, including the rapid development of a human extracorporeal shock wave therapy (ESWT) study in complex wounds after establishing the potential efficacy, biologic mechanisms, and safety of this treatment modality in a murine model. Additional clinical trials include the prospective use of clinical data, serum and wound biomarkers, and wound gene expression profiles to predict wound healing/failure and additional clinical patient outcomes following combat-related trauma. These clinical research data are analyzed using machine-based learning algorithms to develop predictive treatment models to guide clinical decision-making. Future CWI directions include additional clinical trials and study centers and the refinement and deployment of our genetically driven, personalized medicine initiative to provide patient-specific care across multiple medical disciplines, with an emphasis on combat casualty care.

    Corneal wound healing is an enormously complex process that requires the simultaneous cellular integration of multiple soluble biochemical cues, as well as cellular responses to the intrinsic chemistry and biophysical attributes associated with the matrix of the wound space. Here, we document how the biomechanics of the corneal stroma are altered through the course of wound repair following keratoablative procedures in rabbits. Further we documented the influence that substrate stiffness has on stromal cell mechanics. Following corneal epithelial debridement, New Zealand white rabbits underwent phototherapeutic keratectomy (PTK) on the right eye (OD). Wound healing was monitored using advanced imaging modalities. Rabbits were euthanized and corneas were harvested at various time points following PTK. Tissues were characterized for biomechanics with atomic force microscopy and with histology to assess inflammation and fibrosis. Factor analysis was performed to determine any discernable patterns in wound healing parameters. The matrix associated with the wound space was stiffest at 7days post PTK. The greatest number of inflammatory cells were observed 3days after wounding. The highest number of myofibroblasts and the greatest degree of fibrosis occurred 21days after wounding. While all clinical parameters returned to normal values 400days after wounding, the elastic modulus remained greater than pre-surgical values. Factor analysis demonstrated dynamic remodeling of stroma occurs between days 10 and 42 during corneal stromal wound repair. Elastic modulus of the anterior corneal stroma is dramatically altered following PTK and its changes coincide initially with the development of edema and inflammation, and later with formation of stromal haze and population of the wound space with myofibroblasts. Factor analysis demonstrates strongest correlation between elastic modulus, myofibroblasts, fibrosis and stromal haze thickness, and between edema and central corneal

    To evaluate the effectiveness of superoxidized water (MicrocynTM) in diabetic patients with different wounds. One hundred known diabetic patients were enrolled. Half were randomized to the intervention group (those whose wounds were managed with superoxidized water) and half to the control group (whose wounds were treated with normal saline) using a table of random numbers. The two groups were matched for age, gender, duration of diabetes and category of wound. All patients received appropriate surgical treatment for their wounds as required. Local wound treatment was carried out daily using superoxidized water soaked gauzes on twice daily basis in the intervention group and normal saline in the control group. The treatment was continued until wound healing. The main outcome measures were duration of hospital stay, downgrading of the wound category, wound healing time and need for interventions such as amputation. Statistically significant differences were found in favour of the superoxidized water group with respect to duration of hospital stay, downgrading of the wound category and wound healing time. Although the initial results of employing superoxidized water for the management of infected diabetic wounds are encouraging, further multicentre clinical trials are warranted before this antiseptic is recommended for general use. It may offer an economical alternative to other expensive antiseptics with positive impact on the prevailing infection rates, patient outcomes and patient satisfaction. (author)

    Telemedicine is widely considered as an efficient approach to manage the growing problem of chronic wounds. However, to date, there is no convincing evidence to support the clinical efficacy of telemedicine in wound management. In this prospective cluster controlled study, we tested the hypothesis that advice on wound management provided by a team of wound-care specialists through telemedicine would significantly improve the likelihood of wound healing compared with the best available conventional practice. A total of 90 chronic wound patients in home care met all study criteria and were included: 50 in the telemedicine group and 40 in the conventional group. Patients with pressure ulcers, surgical wounds, and cancer wounds were excluded. During the 1-year follow-up, complete wound healing was achieved in 35 patients (70%) in the telemedicine group compared with 18 patients (45%) in the conventional group. After adjusting for important covariates, offering advice on wound management through telemedicine was associated with significantly increased healing compared with the best available conventional practice (telemedicine vs. conventional practice: adjusted hazard ratio 2.19; 95% confidence interval: 1.15-4.17; P=0.017). This study strongly supports the use of telemedicine to connect home-care nurses to a team of wound experts in order to improve the management of chronic wounds.

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

    Wound contraction of both traumatic and surgical origin may reduce or limit the function of the tissue. Myofibroblasts are cells involved on the process of wound contraction, which is smaller on CO2 Laser wounds. The aims of this study were to quantitative and statistically assess the presence of myofibroblasts on both conventional and CO2 Laser wounds. Thirty-two animals (rattus norvegicus) were divided into four groups and operated using either the CO2 Laser (groups A1 and A2) or conventional scalpel (groups B1 and B2). The animals were sacrificed eight days post-operatively (groups: A1 and B1) and 14th days after surgery (groups: A2 and B2). The spec imens we re routinely processed to wax and stained with a-Smooth Muscle Actin (aSMA) and analyzed under light microscopy (40X). Two standard areas around the wound of each slide were selected and used to count the number of myofribroblasts present using a calibrated eyepiece and a graticule. The number of myofibroblasts at day eight was significantly higher than at day 14th. Comparison of the two techniques at day eight showed significant differences between the two groups (Laser, p=0.007 and scalpel, p=0.001). The number of cells present on group B1 was significantly higher than group A1 (p=0.001). However at the 14th day there was no such difference (p=0,072). It is concluded that the small number of myofibroblasts at day eight after wounding with the CO2 Lasermay be the reason why contraction on this wound is smaller than the one observed in conventional surgery.

    This study retrospectively reviewed spine surgical procedures complicated by wound infection and managed by a protocol including the use of vacuum-assisted wound closure (VAC). To define factors influencing the number of debridements needed before the final wound closure by applying VAC for patients with postoperative spinal wound infections. VAC has been suggested as a safe and probably effective method for the treatment of spinal wound infections. The risk factors for infection resistance and need for debridement revisions after VAC placement are unknown. Seventy-three consecutive patients with 79 wound infections after undergoing spine surgery were studied (6 of them had recurrence of infection). All patients were taken to the operating room for irrigation and debridement under general anesthesia followed by placement of the VAC with subsequent delayed closure of the wound. Linear regression and t test were used to identify if the following variables were risk factors for the resistance of infection to VAC treatment: timing of clinical appearance of infection, depth of infection (deep or superficial), presence of instrumentation, positive culture for methicillin-resistant Staphylococcus aureus (MRSA) or more than 1 microorganism, age of the patient, and presence of other comorbidities. There were 34 males and 39 females with an average age of 58.4 years (21 to 82). Once the VAC was initiated, there was an average of 1.4 procedures until and including closure of the wound. The wound was closed an average of 7 days (range 5 to 14) after the placement of the initial VAC on the wound. The average follow-up was 14 months (range 12 to 28). All of the patients but 2 achieved a clean, closed wound without removal of instrumentation at a minimum follow-up of 1 year. Sixty patients had implants (instrumentation or allograft) within the site of wound infection. Thirteen patients had a decompression with exposed dura. Sixty-four infections (81%) presented with a draining

    Hearing of eyeball movements has been reported in superior semicircular canal dehiscence (SSCD), but not hearing of eyelid movements. Our main objective was to report the hearing of eyeball and/or eyelid movements in unilateral SSCD. Our secondary objective was to access its specificity to SSCD and discuss the underlying mechanism. Six patients with SSCD who could hear their eyeball and/or eyelid movements were retrospectively reviewed. With the aim of comparisons, eight patients with an enlarged vestibular aqueduct (EVA), who share the same mechanism of an abnormal third window, were questioned on their ability to hear their eyeball and/or eyelid movements. Three patients with SSCD could hear both their eyeball and eyelid movements as a soft low-pitch friction sound. Two patients with SSCD could hear only their eyelid movements, one of whom after the surgery of a traumatic chronic subdural hematoma. The latter remarked that every gently tapping on the skin covering the burr-hole was heard in his dehiscent ear as the sound produced when banging on a drum, in keeping with a direct transmission of the sound to the inner ear via the cerebrospinal fluid. One patient with SSCD, who could hear only his eyeball movements, had other disabling symptoms deserving operation through a middle fossa approach with an immediate relief of his symptoms. None of the eight patients with EVA could hear his/her eyeball or eyelid movements. Hearing of eyeball and/or eyelid movements is highly suggestive of a SSCD and do not seem to occur in EVA. In case of radiological SSCD, clinicians should search for hearing of eyeball and/or eyelid movements providing arguments for a symptomatic dehiscence. The underlying mechanism is discussed particularly the role of a cerebrospinal fluid transmission.

    Full Text Available Introduction: Vaginal cuff dehiscence after hysterectomy is a rare complication and occurs in less than 1% of patients. It can present with serious complications, such as bowel evisceration and peritonitis. Presentation of case: A 51-year-old multigravida Korean woman underwent total laparoscopic hysterectomy for leiomyoma. Six months later, she reported lower abdominal pain and vaginal bleeding. Physical examination revealed rebound tenderness in the lower abdomen, and pelvic examination showed a small amount of vaginal bleeding with an evisceration of the small intestine through the vagina that exhibited healthy peristalsis. The eviscerated bowel, which seemed to be a part of the ileum, was carefully manually reduced transvaginally into the abdominal cavity. Laparoscopic observation revealed adhesions between the omentum, small intestine, and the peritoneum. Specifically, the small intestine was adhered around the vaginal cuff. An abdominal abscess was found in the left lower abdominal cavity. An adhesiotomy was performed and the abdominal abscess was removed and irrigated. Complete separation of the anterior and posterior vaginal cuff edges was obtained. The vaginal cuff was closed with interrupted 0-polydioxanone absorbable sutures without bowel injury. A 6-month follow-up examination revealed complete healing of the vaginal cuff. Discussion: In this case, we were able to make use of both laparoscopic and transvaginal methods to perform a successful repair with a minimally invasive and safe technique. Conclusion: Laparoscopically assisted vaginal cuff suturing for vaginal cuff dehiscence after total laparoscopic hysterectomy was found to be effective, safe, and minimally invasive.

    2009-10-01

    Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown.

  4. Bidirectional Barbed Sutures for Wound Closure: Evolution and Applications

    Science.gov (United States)

    Paul, Malcolm D.

    2009-01-01

    Traditionally, wound closure sutures have in common the need to tie knots with the inherent risk of extrusion, palpability, microinfarcts, breakage, and slippage. Bidirectional barbed sutures have barbs arrayed in a helical fashion in opposing directions on either side of an unbarbed midsegment. This suture is inserted at the midpoint of a wound and pulled through till resistance is encountered from the opposing barbs; each half of the suture is then advanced to the lateral ends of the wound. This design provides a method of evenly distributing tension along the incision line, a faster suture placement and closure time with no need to tie knots, and the possibility of improved cosmesis. Bidirectional barbed sutures, which are available in both absorbable and nonabsorbable forms, can be used for simple closures, multilayered closures, and closure of high-tension wounds in a variety of surgical settings.

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

  8. Triterpenes for Well-Balanced Scar Formation in Superficial Wounds

    2016-08-01

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

    To examine the correlation between mean arterial pressure (MAP) and wound healing indices and describe an analytical process that can be used accurately and prospectively when evaluating all types of skin ulcerations. A correlational study in a long-term-care facility.Participants (N = 230) were adults residing in a long-term-care facility with an average age of 77.8 years (range, 35-105). Assessment through both an index of wound healing and wound surface area. Signs of wound healing included a reduction of surface area and surface necrosis and increased granulation or epithelialization. Aggregate analyses for all wound locations revealed a positive correlation between the MAP and index of wound healing (r = 0.86, n = 501, P wound healing was noted for all wound locations in this data set when MAP values were 80 mm Hg or less (r = 0.95, n = 141, P wounds and MAP of less than 80 mm Hg yielded a very strong positive correlation. The data indicated that as perfusion decreased, wounds within the sample population declined (r = 0.93, n = 102, P wound healing or worsened wounds. A predictability of wounds stalling or declining related to the MAP was observed, regardless of topical treatment or standard-of-care interventions. Therefore, the data also suggest that remediating states of low perfusion should take precedence in making treatment decisions.

    2015-02-01

    The aim of this article was to identify the literature that examined and explored physical and psychological morbidity and patient and family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. A systematic review of the literature using the databases MEDLINE, CINAHL and EMBASE was undertaken. The papers were examined using title and abstract for relevance to the primary and secondary outcomes. The primary outcome of interest was family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. The search yielded 275 records after removing any duplicates; eight studies were considered eligible and were reviewed as full text. Following full review, none of the studies was included in this article. To conclude, there were no papers that investigated or examined the concept of resilience in relation to the management of acute post-surgical orthopaedic wounds. Four of the papers identified, following the review process, did discuss quality of life outcomes and how these may be improved following wound development; most papers focused on the management of chronic wounds. It is apparent from the review that there is no evidence currently available that explores patient and family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. © 2013 The Authors.

    The development of molecular biology and other new biotechnologies helps us to recognize the wound healing and non-healing wound of skin in the past 30 years. This review mainly focuses on the molecular biology of many cytokines (including growth factors) and other molecular factors such as extracellular matrix (ECM) on wound healing. The molecular biology in cell movement such as epidermal cells in wound healing was also discussed. Moreover many common chronic wounds such as pressure ulcers, leg ulcers, diabetic foot wounds, venous stasis ulcers, etc. usually deteriorate into non-healing wounds. Therefore the molecular biology such as advanced glycation end products (AGEs) and other molecular factors in diabetes non-healing wounds were also reviewed.

    The current trend in minimally invasive surgery is to make a small surgical incision. However, the excessive tensile stress applied by the retractors to the skin surrounding the incision often results in a long wound healing time and extensive scarring. To minimize these types of wound problems, the authors evaluated a simple and cost-effective method to minimize surgical incision scars based on the use of a latex surgical glove. The tunnel-shaped part of a powder-free latex surgical glove was applied to the incision and the dissection plane. It was fixed to the full layer of the dissection plane with sutures. The glove on the skin surface then was sealed with Ioban (3 M Health Care, St. Paul, MN, USA) to prevent movement. The operation proceeded as usual, with the retractor running through the tunnel of the latex glove. It was possible to complete the operation without any disturbance of the visual field by the surgical glove, and the glove was neither torn nor separated by the retractors. The retractors caused traction and friction during the operation, but the extent of damage to the postoperative skin incision margin was remarkably less than when the operation was performed without a glove. This simple and cost-effective method is based on the use of a latex surgical glove to protect the surgical skin incision site and improve the appearance of the postoperative scar.

    To explore ocular vestibular evoked myogenic potentials (oVEMP) to low-frequency vertex vibration (125 Hz) as a diagnostic test for superior canal dehiscence (SCD) syndrome. The oVEMP using 125 Hz single cycle bone-conducted vertex vibration were tested in 15 patients with unilateral superior canal dehiscence (SCD) syndrome, 15 healthy controls and in 20 patients with unilateral vestibular loss due to vestibular neuritis. Amplitude, amplitude asymmetry ratio, latency and interaural latency difference were parameters of interest. The oVEMP amplitude was significantly larger in SCD patients when affected sides (53 μVolts) were compared to non-affected (17.2 μVolts) or compared to healthy controls (13.6 μVolts). Amplitude larger than 33.8 μVolts separates effectively the SCD ears from the healthy ones with sensitivity of 87% and specificity of 93%. The other three parameters showed an overlap between affected SCD ears and non-affected as well as between SCD ears and those in the two control groups. oVEMP amplitude distinguishes SCD ears from healthy ones using low-frequency vibration stimuli at vertex. Amplitude analysis of oVEMP evoked by low-frequency vertex bone vibration stimulation is an additional indicator of SCD syndrome and might serve for diagnosing SCD patients with coexistent conductive middle ear problems.

    2010-12-15

    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.

    Full Text Available Background. Snakebites can produce severe local and systemic septic complications as well as being associated with significant overall morbidity and even mortality. Objective. A prospective audit was undertaken to determine the bacterial causation of wound infection secondary to snakebite, and attempt to quantify the burden of disease. Methods. The audit was undertaken at Ngwelezane Hospital, which provides both regional and tertiary services for north-eastern KwaZulu-Natal Province, South Africa, over a 4-month period. Records of patients who required surgical debridement for extensive skin and soft-tissue necrosis were analysed. At the time of debridement, tissue samples of necrotic or infected tissue were sent for bacteriological analysis as standard of care. Microbiology results were analysed. Results. A total of 164 patients were admitted to hospital for management of snakebite, of whom 57 required surgical debridement and 42 were included in the final microbiological analysis. Children were found to be the most frequent victims of snakebite; 57.8% of patients in this study were aged ≤10 years and 73.7% ≤15 years. Culture showed a single organism in 32/42 cases, two organisms in 8 and no growth in 2. Eight different types of organisms were cultured, five of them more than once. Thirty-five specimens (83.3% grew Gram-negative Enterobacteriaceae, the most frequent being Morganella morganii and Proteus species. Thirteen specimens (31.0% grew Enterococcus faecalis.

    The study goal was to evaluate the impact of the telemedicine consult on patients with chronic wounds. Thirty patients from long-term care skilled nursing facilities, referred to the ambulatory wound care program for wound assessment and preparation of management plans, were the subject of this prospective, randomized trial. To facilitate communication with a surgical wound care specialist, telemedicine feedback was provided prior to face-to-face consultation to 15 patients. The telemedicine consult included (1) wound assessment, (2) rationale for the suggested wound management with emphasis on wound risk projections, and (3) prevention and benefits of surgical intervention. This was communicated to the patient by the field wound care nurse. The telemedicine impact was measured by assessing the duration of the subsequent face-to-face consultation and patient satisfaction with further care decisions as well as by validation of a decisional conflict scale. The average duration of the face-to-face consultation was 50 +/- 12 minutes versus 35 +/- 6 (p face-to-face evaluation improved patient satisfaction and understanding of their care as well as increased the perception of shared decision making regarding the wound care.

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

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

    To investigate the role of mast cells and vascular endothelial growth factor (VEGF) as a mediator of angiogenesis to promote wound healing in surgical and pathological scars. The study was carried out on 40 patients who presented with active scar lesions. They were subdivided into 4 groups. They included granulation tissue (10 cases), surgical scar (10 cases), hypertrophic scar (10 cases), and keloid scar (10 cases). Also 10 healthy volunteers of the same age and sex were selected as a control group. Skin biopsies were taken from the patients and the control group. Skin biopsies from clinically assessed studied groups were processed for routine histology and embedded in paraffin. Four sections were prepared from each paraffin block. The first section was stained with hematoxylin and eosin for histological evaluation. The second and third sections were processed for immunostaining of mast cells that contain chymase (MCCs) and mast cells that contain tryptase (MCTs). The fourth section was processed for immunostaining of VEGF. MCCs exhibited mild expression in normal tissue, granulation tissue, and surgical, hypertrophic and keloid scars. MCTs exhibited mild expression in normal tissue, granulation tissue and keloid, whereas moderate expression was exhibited in hypertrophic and surgical scars. VEGF expression was absent in normal tissue, mild in keloid, surgical and hypertrophic scars, and moderate in keloids and granulation tissue. Mast cell expression variation among different scar types signals the pathological evolution of the lesion, and hence may guide the need for therapeutic intervention.

    When traumatic wounds are quickly and accurately treated, morbidity and costs can be significantly decreased. Several factors, such as time delay between injury and treatment, the degree of contamination, extension and depth of the wound, and the mechanism of injury, influence the treatment and prognosis and stress the importance of a patient-specific approach. Although all traumatic wounds are contaminated, antibiotic therapy is seldom required if correct wound management is installed. Copyright © 2017 Elsevier Inc. All rights reserved.

    The objective of this study was to evaluate the effect of a novel recombinant human GDF-5 (rhGDF-5) construct intended for onlay and inlay indications on periodontal wound healing/regeneration. Contralateral, surgically created, critical-size, 6-mm, supra-alveolar periodontal defects in five adult Hound Labrador mongrel dogs received rhGDF-5 coated onto beta-tricalcium phosphate (beta-TCP) particles and immersed in a bioresorbable poly(lactic-co-glycolic acid) (PLGA) composite or the beta-TCP/PLGA carrier alone (control). The rhGDF-5 and control constructs were moulded around the teeth and allowed to set. The gingival flaps were then advanced; flap margins were adapted 3-4 mm coronal to the teeth and sutured. The animals were euthanized at 8 weeks post-surgery when block biopsies were collected for histometric analysis. Healing was generally uneventful. A few sites exhibited minor exposures. Three control sites and one rhGDF-5 site (in separate animals) experienced more extensive wound dehiscencies. The rhGDF-5 and control constructs were easy to apply and exhibited adequate structural integrity to support the mucoperiosteal flaps in this challenging onlay model. Limited residual beta-TCP particles were observed at 8 weeks for both rhGDF-5/beta-TCP/PLGA and beta-TCP/PLGA control sites. The rhGDF-5/beta-TCP/PLGA sites showed significantly greater cementum (2.34 +/- 0.44 versus 1.13 +/- 0.25 mm, p=0.02) and bone (2.92 +/- 0.66 versus 1.21 +/- 0.30 mm, p=0.02) formation compared with the carrier control. Limited ankylosis was observed in four of five rhGDF-5/beta-TCP/PLGA sites but not in control sites. Within the limitations of this study, the results suggest that rhGDF-5 is a promising candidate technology in support of periodontal wound healing/regeneration. Carrier and rhGDF-5 dose optimization are necessary before further advancement of the technology towards clinical evaluation.

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

    Frank J. Lebeda

    2012-01-01

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

    Recent advances in bioengineering have introduced materials that enhance wound healing. Even with such new tools, some deep ulcers surrounded by avascular tissues, including bone, tendon, and fascia, are resistant to various therapies and easily form deep cavities with loss of subcutaneous tissue. Atelocollagen sponges have been used as an artificial dermis to cover full-thickness skin defects. Topical recombinant human basic fibroblast growth factor has been introduced as a growth factor to induce fibroblast proliferation in skin ulcers. We applied these materials in combination in two patients with deep resistant wounds: one with a cavity reaching the mediastinum through a divided sternum and one with deep necrotic wounds caused by electric burns. These wounds did not respond to the topical basic fibroblast growth factor alone. In contrast, the combination therapy closed the wounds rapidly without further surgical treatment. This combination therapy is a potent treatment for resistant wounds with deep cavities.

The study used twelve (12 adult male albino rats (130 ± 20 g, randomly grouped into Electro-cautery (n = 6 and Cold scalpel (n = 6. Each rat had three full thickness (6 mm diameter skin wounds (a, b and c created on its dorsum with either Electroscalpel (ES or Cold blade scalpel (CS, and treated topically with Silver sulphadiazine (SSD, wound a, untreated (control, wound b and Bee honey (H, wound c. The wounds were evaluated for gross (exudation, edema, hyperemia, contraction, histologic (granulation, angiogenesis, fibroplasia, epithelialization and immunologic healing indices using standard techniques. Data were analyzed with Chi-square, Two-way Analysis of Variance (ANOVA and Duncan Multiple Range tests (DMRT at α = 0.05. Wound hyperemia and edge edema were prominent in the ES group from day 4 to 6 (P = .000. Percentage wound contraction was higher in the CS than ES group from days 5 to 7 (P = .006 and in the CS treated with honey than ES treated with honey from days 7 to 14 (P = .000. Granulation tissue reduced in ES group treated with SSD than in honey and control wounds. Fibroelastic tissue increased in SSD and honey treated wounds of ES group, and higher in honey treated wounds of CS group (P < .05. Fibroplasia was sustained in honey and SSD treated wounds than control. Honey can be applied to electroscalpel surgical wound to facilitate rapid healing during surgical management of tumours having vascular network.

    Impaired wound healing in the elderly represents a major clinical problem that is growing as our population ages. Wound healing is affected by age and by co-morbid conditions, particularly diabetes and obesity. This is particularly important in Rhode Island as the state has a very high percentage of vulnerable older adults. A multi- disciplinary approach that incorporates the skills of a comprehensive wound center with specialized nursing, geriatric medicine and palliative care will facilitate rapid wound healing, reduce costs and improve outcomes for our older adults that suffer from 'problem wounds'.

  14. Clinically relevant doses of lidocaine and bupivacaine do not impair cutaneous wound healing in mice.

    Lidocaine and bupivacaine are commonly infiltrated into surgical cutaneous wounds to provide local anaesthesia after surgical procedures. However, very little is known about their effects on cutaneous wound healing. If an inhibitory effect is demonstrated, then the balance between the benefits of postoperative local anaesthesia and the negatives of impaired cutaneous wound healing may affect the decision to use local anaesthesia or not. Furthermore, if a difference in the rate of healing of lidocaine- and bupivacaine-treated cutaneous wounds is revealed, or if an inhibitory effect is found to be dose-dependent, then this may well influence the choice of agent and its concentration for clinical use. Immediately before incisional wounding, we administered lidocaine and bupivacaine intradermally to adult female mice, some of which had been ovariectomized to act as a model of post-menopausal women (like post-menopausal women, ovariectomized mice heal wounds poorly, with increased proteolysis and inflammation). Day 3 wound tissue was analysed histologically and tested for expression of inflammatory and proteolytic factors. On day 3 post-wounding, wound areas and extent of re-epithelialization were comparable between the control and local anaesthetic-treated animals, in both intact and ovariectomized groups. Both tested drugs significantly increased wound activity of the degradative enzyme matrix metalloproteinase-2 relative to controls, while lidocaine also increased wound neutrophil numbers. Although lidocaine and bupivacaine influenced local inflammatory and proteolytic factors, they did not impair the rate of healing in either of two well-established models (mimicking normal human wound healing and impaired age-related healing).

    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.

Each filament band in each band set is wound at the same helix angle from the axis of revolution of the mandrel and all of the bands of each set are uniformly distributed about the mandrel circumference. The pole-to-equator wall thickness taper associated with each band set, as several contiguous band sets are wound about the mandrel starting at the poles, is accumulative as the band sets are nested to provide a complete filament wound sphere of essentially uniform thickness

    Full Text Available Flavonoids represent one of the main groups of substances with pharmacological activities in plants. They are used to increase the effectiveness of the healing process in wounds and ulcers. Propolis and green tea (Camellia sinensis are two products rich in flavonoids that present indications as: anti-inflammatory antibacterial, antioxidant and healing ones. The present study aims to evaluate the action of propolis and green tea on the healing process in clean wounds. The wounds were produced in 20 Wistar rats. In each rat two symmetrical lesions of 11 mm diameter were induced using a surgical punch. The lesions were located on the left and right sides of the lateral thoracic region. Later the rats were divided in 2 groups. Group 1 – treated with 0.9% physiologic solution (left side, and with green teabased cream (Camellia sinensis at 20% (right side; Group 2 – treated with base cream (left side and treated with propolis-based cream at 20% (right side. The lesions diameters were measured every three days. The lesions healing was observed after 15 days, and there was no significant difference among the treatments, despite groups treated with green tea and propolis cream presenting better evolution during the treatment.

    The objective of this study is to compare the frequency of post circumcision complications like bleeding and infection along with wound healing in infants by conventional open method and the bone-cutter method. Study Design: Randomized controlled trial. Place and Duration of Study: Combined Military Hospital and Military Hospital Rawalpindi, from March 2009 to March 2010. Patients and Methods: A total of 400 patients were included in the study that underwent circumcision. Patients were randomly allotted to either group A in whom the circumcision was done with conventional open technique (n = 200) or to group B, in whom circumcision was done with bone-cutter (n = 200). Patients were followed up in the surgical OPD after 5 days for assessment and earlier in case of any complication. Outcomes were measured by absence or presence of infection, post operative bleeding and cosmetic acceptance by the parents. Results: Comparison between the two groups showed that the bleeding rate was 8% in group A and 7% in group B (p = 0.704). Infection rate was 6% in group A and 5% in group B (p = 0.661). Delayed wound healing was seen in 4% of circumcisions in group A as opposed to 2% in group B ( p = 0.241). Conclusion: Complication is a part of any surgical procedure. So is the case with circumcision however no significant difference was found between the two procedures in terms of bleeding, infection, trauma to the glans and the cosmetic outcome. (author)

    Idiopathic esophageal achalasia is an inflammatory disease of unknown origin, characterized by aperistalsis of the esophageal body and failure of the lower esophageal sphincter in response to swallowing, with consequent dysphagia. To demonstrate the results of surgical therapy in these patients, evaluating the occurred local and systemic complications. Were studied retrospectively 32 patients, 22 of whom presented non-advanced stage of the disease (Stage I/II) and 10 with advanced disease (Stage III/IV). All of them had the clinical conditions to be submitted to surgery. The diagnoses were done by clinical, endoscopic, cardiological, radiological and esophageal manometry analysis. Pre-surgical evaluation was done with a questionnaire based on the most predisposing factors in the development of the disease and the surgical indication was based on the stage of the disease. The patients with non-advanced stages were submitted to cardiomyotomy with fundoplication, wherein in the post-surgical early assessment, only one (4,4%) presented pulmonary infection, but had a good outcome. In patients with advanced disease, seven were submitted to esophageal mucosectomy preserving the muscular layer, wherein one patient (14,2%) presented dehiscence of gastric cervical esophagus anastomosis as well as pulmonary infection; all of these complications were resolved with proper specific treatment; the other three patients with advanced stage were submitted to transmediastinal esophagectomy; two of them presented hydropneumothorax with good evolution, and one of them also presented fistula of the cervical esophagogastric anastomosis, but with spontaneous healing after conservative treatment and nutritional support. The two patients with fistula of the cervical anastomosis progressed to stenosis, with good results after endoscopic dilations. In the medium and long term assessment done in 23 patients, all of them reported improvement in life quality, with return to swallowing. The

    Full Text Available 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.

    Vascular groin wounds have higher than expected surgical site infection (SSI) rates and some patients are at enhanced risk. The Wiseman et al. paper suggests an objective scoring system that identifies patients at enhanced risk of postdischarge SSI. We hypothesize that prophylactic groin wound vacuum-assisted closure (VAC) therapy in enhanced risk patients will decrease SSI and readmission and the Wiseman model provides potential evidence that enhanced risk patients can be objectively identified. A single institution, retrospective analysis was conducted from January 2013 to September 2016 utilizing procedure codes to identify patients with wound VACs placed in the operating room. Two distinct groups were identified. The first was a wound complication patient group with 15 limbs (13 patients) with a groin wound VAC placed within 45 days postoperatively for groin wound complications. Eleven of these limbs had the VAC placed at readmission. The second group was a prophylactic patient group that included 8 limbs (7 patients) who received a VAC prophylactically placed in the enhanced risk wounds. These wounds were determined to be enhanced risk based on clinical criteria judged by the operating surgeon such as a large overhanging panniculus and/or one of several ongoing medical issues. We calculated a Wiseman score for all patients, determined total cost of the readmissions, and determined 30-day postsurgical SSI incidence for the prophylactic VAC group. Per the Wiseman scores, 9 limbs with postoperative complications were high risk and 3 limbs were moderate/high risk. Eleven limbs had a VAC placed at readmission with an average readmission cost of $8876.77. For the prophylactic group, 8 limbs were high risk with no observed postdischarge SSI in the first 30 days from surgery. The Wiseman scores showed close correlation between the retrospective high and moderate/high risk groups versus the prophylactic VAC group (31.5 ± 7.3 vs. 32 ± 5.5, P = 0.87). The Wiseman

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

    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.)

    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

Multicenter retrospective chart review (Canadian Task Force classification II-3). Nine US academic medical centers participating in the Fellows' Pelvic Research Network (FPRN). One hundred twenty-seven women with premenopausal breast cancer undergoing oophorectomy between January 2013 and March 2016. Surgical castration. The mean patient age was 45.8 years. Fourteen patients (11%) carried a BRCA mutations, and 22 (17%) carried another germline or acquired mutation, including multiple variants of uncertain significance. There was wide variation in surgical approach. Sixty-five patients (51%) underwent pelvic washings, and 43 (35%) underwent concurrent hysterectomy. Other concomitant procedures included midurethral sling placement, appendectomy, and hysteroscopy. Three patients experienced complications (transfusion, wound cellulitis, and vaginal cuff dehiscence). Thirteen patients (10%) had ovarian pathology detected on analysis of the surgical specimen, including metastatic tumor, serous cystadenomas, endometriomas, and Brenner tumor. Eight patients (6%) had Fallopian tube pathology, including 3 serous tubal intraepithelial cancers. Among the 44 uterine specimens, 1 endometrial adenocarcinoma and 1 multifocal endometrial intraepithelial neoplasia were noted. Regarding the entire study population, the number of patients meeting our study criteria and seen by gynecologic surgeons in the FPRN for oophorectomy increased by nearly 400% from 2013 to 2015. Since publication of the Suppression of Ovarian Function Trial data, bilateral oophorectomy has been recommended for some women with premenopausal breast cancer to facilitate breast cancer treatment with aromatase inhibitors. These women may be at elevated risk for occult abdominal pathology compared with the general population. Gynecologic surgeons

    The article reviews some commonly used orthodontic treatments as well as new strategies to assist in the correction of malocclusion. Many techniques are used in conjunction with surgical intervention and are a necessary compliment to orthognathic surgery. Basic knowledge of these practices will aid in the surgeon's ability to adequately treat the patient. Many orthodontists and surgeons are eliminating presurgical orthodontics to adopt a strategy of 'surgery first' orthodontics in orthognathic surgery. This has the benefit of immediate improvement in facial aesthetics and shorter treatment times. The advent of virtual surgical planning has helped facilitate the development of this new paradigm by making surgical planning faster and easier. Furthermore, using intraoperative surgical navigation is improving overall precision and outcomes. A variety of surgical and nonsurgical treatments may be employed in the treatment of malocclusion. It is important to be familiar with all options available and tailor the patient's treatment plan accordingly. Surgery-first orthodontics, intraoperative surgical navigation, virtual surgical planning, and 3D printing are evolving new techniques that are producing shorter treatment times and subsequently improving patient satisfaction without sacrificing long-term stability.

    Neonatal ostomies, either temporary or permanent, are created for numerous reasons. Limited attention has been given to understanding what factors might place infants at risk for surgical wound complications. The purpose of the study is to identify factors associated with risk of significant abdominal wound complications (wound dehiscence and wound infection) following neonatal ostomy creation. This is a retrospective chart review of infants undergoing ostomy between January 2009 and December 2013 at the University of Alberta Hospital. 66 infants were identified of which 18.2% (12/66) had wound complications. Variables associated with wound dehiscence included: findings of bowel necrosis during laparotomy (7/9 wound dehiscence, 18/57 none, p=0.008), perioperative sepsis (3/9 wound dehiscence, 3/57 none, p=0.006), and perioperative blood transfusion (9/9 wound dehiscence, 30/57 none, p=0.007). Wound infection was not predicted by any variables collected. Neonates undergoing creation of an ostomy appear to be at substantial risk for wound complications. As wound complications are significant issues for infants undergoing surgery, emerging strategies should be explored to either avoid ostomy creation or promote wound healing.

    Penetrating cardiothoracic war wounds are very common among war casualties. Those injuries require prompt and specific treatment in an aim to decrease mortality and late morbidity. There are a few controversies about the best modality of treatment for such injuries, and there are not many large series of such patients in recent literature. We analysed a group of 259 patients with penetrating cardiothoracic war wounds admitted to our institutions between May 1991 and October 1992. There were 235 (90.7%) patients with thoracic wounds, 14 (5.4%) patients with cardiac, wounds and in 10 (3.7%) patients both heart and lungs were injured. The cause of injury was shrapnel in 174 patients (67%), bullets in 25 patients (9.7%), cluster bomb particles in 45 patients (17.3%) and other (blast etc.) in 15 patients (6%). Patients, 69, had concomitant injuries of various organs. The initial treatment in 164 operated patients was chest drainage in 76 (46.3%) patients, thoracotomy and suture of the lung in 71 (43.2%) patients, lobectomy in 12 (7.3%) patients and pneumonectomy in 5 (3%) patients. Complications include pleural empyema and/or lung abscess in 20 patients (8.4%), incomplete reexpansion of the lung in 10 patients (4.2%), osteomyelitis of the rib in 5 patients (2.1%) and bronchopleural fistula in 1 patient (0.4%). Secondary procedures were decortication in 12 patients, rib resection in 5 patients, lobectomy in 2 patients, pneumonectomy in 4 patients, reconstruction of the chest wall in 2 patients and closure of the bronchopleural fistula in 1 patient. The cardiac chamber involved was right ventricle in 12 patients, left ventricular in 6 patients, right atrium in 7 patients, left atrium in 3 patients, ascending aorta in 2 patients and 1 patient which involved descending aorta, right ventricle and coronary artery (left anterior descending) and inferior vena cava, respectively. The primary procedure was suture in 17 patients (in 10 patients with the additional suture of the

    Surgical resection of many tumours following radiotherapy is well established as the preferred approach to eradicating the disease. However, prior irradiation compromises the healing of surgical wounds in 30-60% of cases, depending on the site of treatment. There is a need therefore, to understand the deficit in the repair process and to develop therapeutic interventions that may help address this problem. To this end, the aims of this thesis were to characterise a wound healing model in irradiated murine skin and to investigate the effects of topical- compounds and therapeutic modalities upon this wound healing model. Full-thickness dorsal skin excisions were made within a pre-irradiated area (20Gy) in male Balb/c mice and wounds were made in a corresponding area in control animals. Biopsies were removed for histological and immunohistochemical analysis, whilst wound closure experiments were used to determine effects of topical compounds and therapeutic modalities (Low Intensity Laser Therapy, Therapeutic Ultrasound and Transcutaneous Electrical Nerve Stimulation) upon the rate of repair. X-ray irradiation (20Gy) caused a significant delay in the rate of wound closure, whilst histological results indicated that prior irradiation delays the influx of inflammatory cells, delays wound reepithelialisation and reduces granulation tissue formation and collagen deposition. Macrophage and endothelial cell numbers were found to be significantly lower in the irradiated wounds when compared to unirradiated control wounds. Furthermore, apoptosis was affected by irradiation. Although results failed to support any claimed stimulatory effects of various therapeutic modalities upon wound healing, topical application of glucans were shown to have a slight beneficial effect upon the rate of repair. In conclusion, the observed cellular effects caused by irradiation may be a result of permanent damage to stem cells and their ability to replicate and reproduce. Furthermore, the

    Results of surgical treatment of 61 patients with injuries of the duodenum are analyzed. The causes of injuries were stab-incised wounds in 24 patients, missile wound -- in 7, closed abdominal trauma -- in 26, trauma of the duodenum during endoscopic papillosphincterotomy -- in 4. All the patients underwent surgery. Complications were seen in 32 (52.5%) patients, 21 patients died, lethality was 34.4%. Within the first 24 hours since the trauma 7 patients died due to severe combined trauma, blood loss, 54 patients survived acute period of trauma, including 28 patients after open trauma, 26 -- after closed and 4 -- after trauma of the duodenum during endoscopic papillosphincterotomy. Diagnostic and surgical policies are discussed. Results of treatment depending on kind and time of surgery are regarded. It is demonstrated that purulent complications due to retroperitoneal phlegmona, traumatic pancreatitis, pneumonia are the causes of significant number of unfavorable outcomes. Therefore, it is important to adequately incise and drainage infected parts of retroperitoneal fat tissue with two-lumen drainages. Decompression through duodenal tube is the effective procedure for prophylaxis of suture insufficiency and traumatic pancreatitis. Suppression of pancreatic and duodenal secretion with octreotid improves significantly surgical treatment results.

    The winding process is encountered frequently in manufacturing, such as winding of polymer films and paper, laminated pressure vessel construction, and the manufacture of wound capacitors. The winding of capacitors will typically involve hundreds of plies of conductor and dielectric wound over a core. Due to the large number of layers, the calculation of the mechanical studies within a wound capacitor is a significant computational task. The focus of Part II of this paper is the formulation and application of optimization techniques for the design of wound capacitors. The design criteria to be achieved is a specified uniform wound tension in a capacitor. The paper will formulate an optimization statement of the wound capacitor design problem, develop a technique for reducing the numerical calculation required to repeatedly analyze the capacitor as required by the optimization algorithm, and apply the technique to an example. 4 refs., 13 figs., 4 tabs

    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.

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

    Few studies have analysed the bacterial pathogenesis of infections associated with war-wound in the Eastern Mediterranean region. We analysed surgical wound infections of 1200 patients injured during the Libyan conflict in 2011 and admitted to the emergency services at Tripoli medical centre. Culture swabs or surgical wound debridement samples were collected and cultures were identified and tested for antimicrobial resistance. Of the 1200 patients studied, 498 (42%) were infected with at least 1 pathogen and 57 with >2 pathogens. The most common species were Acinetobacter spp. (isolated from 144 patients), coagulase-negative staphylococci (122), Escherichia coli (107), Pseudomnonas aeruginosa (92) and Klebsiella spp. (86). A high level of resistance to the antibiotics tested was found, especially among Acinetobacter spp. Multi-drug-resistant Gram-negative bacilli were an important complicating factor in wound infections associated with war injuries among injured patients in Libya. Effective policies are needed to control and treat such infections particularly in trauma and emergency services.

    Because nurses frequently participate in decisions related to wound care, learning about wounds and their care during undergraduate education is critical. A cross-sectional, descriptive, quality improvement project was conducted in an introductory baccalaureate nursing course to identify: 1) the types of patients with wounds assigned to beginning students, 2) patient wound care procedures and dressings, and 3) student level of participation in wound care. Data were collected from the weekly notes recorded about students' (N = 49) patient care experiences in 3 acute care hospitals for 9 clinical days during 1 semester. Data were recorded on a paper-and-pencil form by instructors at the end of the clinical day and included type of wound, wound irrigation, dressing, technique of care, and student's participation. Descriptive statistics were used to examine the frequency and distribution of the wound characteristics and care assessed. Of the 284 patients assigned to students, 75 (26.4%) had a wound. The most common wound was a surgical incision (49, 65%) and was closed (36, 73.5%). Twenty-six (26) patients had a pressure ulcer, most commonly Stage II. The most common dressing was dry gauze (29). Damp gauze was used on 18 wounds. Wound irrigation was recorded for 24 wound protocols and performed with a bulb syringe or by pouring the solution from a container. Generally, nonsterile wound care was performed. Twenty-five (25) students performed wound care with the instructor, 16 watched the care performed by another clinician, and 10 participated with another nurse in the wound care. For 22 patients, the wound care was neither observed nor performed because either it was not time for the dressing to be changed or it was only to be changed by a medical team. From these data, it was concluded beginning nursing students had some, but limited, clinical experience with patients with wounds. Students' wound care experiences need further examination, especially across multiple

    At beginning of 1991, the increasing necessity of emergency surgical treatment of wounded persons in Croatia led to the formation of mobile surgical teams. However, this system was abandoned due to many problems and echelon health division was formed. One of the war surgical hospitals (second echelon) was the War Surgical Hospital Garesnica. In this study, materials of the Croatian War Veterans Ministry, Ministry of Defense, Garesnica War Surgical Hospital and Garesnica Defense Office archive were used. We analyzed the number and localization of wounds, and describe the organization, work and results of the War Surgical Hospital in Garesnica. During the work of the War Surgical Hospital in Garesnica, 909 surgical examinations were performed, 521 wounded were surgically treated (45% civilians and 55% soldiers), 331 wounded were operated on, 5 lethal outcomes were recorded, 68% of wounds were localized on the extremities, 19% on the thorax and abdomen, and 13% on the head end neck. In this article the organization and work of the War Surgical Hospital in Garesnica is described, which had a major role in providing emergency medical care to people wounded in west Slavonia.

  7. Evaluation of negative pressure vacuum-assisted system in acute and chronic wounds closure: our experience.

    2012-10-01

    Negative-pressure therapy or vacuum-assisted closure (VAC) has been used in clinical applications since the 1940's and has increased in popularity over the past decade. This dressing technique consists of an open cell foam dressing put into the wound cavity, a vacuum pump produces a negative pressure and an adhesive drape. A controlled sub atmospheric pressure from 75 to 150 mmHg is applied. The vacuum-assisted closure has been applied by many clinicians to chronic wounds in humans; however it cannot be used as a replacement for surgical debridement. The initial treatment for every contaminated wound should be the necrosectomy. The VAC therapy has a complementary function and the range of its indications includes pressure sores, stasis ulcers, chronic wounds such as diabetic foot ulcers, post traumatic and post operative wounds, infected wounds such as necrotizing fasciitis or sternal wounds, soft-tissue injuries, bone exposed injuries, abdominal open wounds and for securing a skin graft. We describe our experience with the VAC dressing used to manage acute and chronic wounds in a series of 135 patients, with excellent results together with satisfaction of the patients.

  8. Negative pressure therapy (vacuum for wound bed preparation among diabetic patients: case series

    Directory of Open Access Journals (Sweden)

    Marcus Castro Ferreira

    Full Text Available CONTEXT: Complications from diabetes mellitus affecting the lower limbs occur in 40 to 70% of such patients. Neuropathy is the main cause of ulceration and may be associated with vascular impairment. The wound evolves with necrosis and infection, and if not properly treated, amputation may be the end result. Surgical treatment is preferred in complex wounds without spontaneous healing. After debridement of the necrotic tissue, the wound bed needs to be prepared to receive a transplant of either a graft or a flap. Dressings can be used to prepare the wound bed, but this usually leads to longer duration of hospitalization. Negative pressure using a vacuum system has been proposed for speeding up the treatment. This paper had the objective of analyzing the effects of this therapy on wound bed preparation among diabetic patients. CASE SERIES: Eighty-four diabetic patients with wounds in their lower limbs were studied. A commercially available vacuum system was used for all patients after adequate debridement of necrotic tissues. For 65 patients, skin grafts completed the treatment and for the other 19, skin flaps were used. Wound bed preparation was achieved over an average time of 7.51 days for 65 patients and 10 days for 12 patients, and in only one case was not achieved. CONCLUSIONS: This experience suggests that negative pressure therapy may have an important role in wound bed preparation and as part of the treatment for wounds in the lower limbs of diabetic patients.

    Full Text Available The efficient healing of a skin wound is something that most of us take for granted but is essential for surviving day-to-day knocks and cuts, and is absolutely relied on clinically whenever a patient receives surgical intervention. However, the management of a chronic wound – defined as a barrier defect that has not healed in 3 months – has become a major therapeutic challenge throughout the Western world, and it is a problem that will only escalate with the increasing incidence of conditions that impede wound healing, such as diabetes, obesity and vascular disorders. Despite being clinically and molecularly heterogeneous, all chronic wounds are generally assigned to one of three major clinical categories: leg ulcers, diabetic foot ulcers or pressure ulcers. Although we have gleaned much knowledge about the fundamental cellular and molecular mechanisms that underpin healthy, acute wound healing from various animal models, we have learned much less about chronic wound repair pathology from these models. This might largely be because the animal models being used in this field of research have failed to recapitulate the clinical features of chronic wounds. In this Clinical Puzzle article, we discuss the clinical complexity of chronic wounds and describe the best currently available models for investigating chronic wound pathology. We also assess how such models could be optimised to become more useful tools for uncovering pathological mechanisms and potential therapeutic treatments.

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

    2014-12-01

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

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

    To provide an overview on the biology and soft tissue wound healing around teeth and dental implants. This narrative review focuses on cell biology and histology of soft tissue wounds around natural teeth and dental implants. The available data indicate that: (a) Oral wounds follow a similar pattern. (b) The tissue specificities of the gingival, alveolar and palatal mucosa appear to be innately and not necessarily functionally determined. (c) The granulation tissue originating from the periodontal ligament or from connective tissue originally covered by keratinized epithelium has the potential to induce keratinization. However, it also appears that deep palatal connective tissue may not have the same potential to induce keratinization as the palatal connective tissue originating from an immediately subepithelial area. (d) Epithelial healing following non-surgical and surgical periodontal therapy appears to be completed after a period of 7–14 days. Structural integrity of a maturing wound between a denuded root surface and a soft tissue flap is achieved at approximately 14-days post-surgery. (e) The formation of the biological width and maturation of the barrier function around transmucosal implants requires 6–8 weeks of healing. (f) The established peri-implant soft connective tissue resembles a scar tissue in composition, fibre orientation, and vasculature. (g) The peri-implant junctional epithelium may reach a greater final length under certain conditions such as implants placed into fresh extraction sockets versus conventional implant procedures in healed sites. © 2014 John Wiley & Sons A/S.

    To compare and determine a credible method of measurement of wound surface area by linear, transparency, and photographic methods for monitoring progress of wound healing accurately and ascertaining whether these methods are significantly different. From April 2005 to December 2006, 40 patients (30 men, 5 women, 5 children) admitted to the surgical ward of Shree Sayaji General Hospital, Baroda, had clean as well as infected wound following trauma, debridement, pressure sore, venous ulcer, and incision and drainage. Wound surface areas were measured by these three methods (linear, transparency, and photographic methods) simultaneously on alternate days. The linear method is statistically and significantly different from transparency and photographic methods (P value transparency and photographic methods (P value >0.05). Photographic and transparency methods provided measurements of wound surface area with equivalent result and there was no statistically significant difference between these two methods.

    Recent high-profile cases have heightened the need for a formal structure to monitor achievement and maintenance of surgical competence. Logbooks, morbidity and mortality meetings, videos and direct observation of operations using a checklist, motion analysis devices, and virtual reality simulators are effective tools for teaching and evaluating surgical skills. As the operating theater is also a place for training, there must be protocols and guidelines, including mandatory standards for supervision, to ensure that patient care is not compromised. Patients appreciate frank communication and honesty from surgeons regarding their expertise and level of competence. To ensure that surgical competence is maintained and keeps pace with technologic advances, professional registration bodies have been promoting programs for recertification. They evaluate performance in practice, professional standing, and commitment to ongoing education.

    The efficacy of normal saline irrigation to prevent surgical site Infection The aim of the study was to evaluate the efficacy of normal saline irrigations to prevent surgical site infection (SSI). Study Design: A comparative study. Place and Duration of Study: The study was conducted at surgery and gynecology Dept CMH Chunian from 1st Jan 2012 to 1st Nov 2012. Patients and Methods: Two hundred clean surgical and gynecological cases were included in the study. Hundred cases which were randomly selected had their wound washed with warm normal saline for 60 sec and then mopped dry with clean swabs. Subcuticular Stitches were applied to all the 200 cases. The surgical wounds were examined on 3rd post operative day and then finally on 15th post operative day. Patients with wound infection developed pain at the operation site and fever on third post operative day. Wounds were examined for swelling, redness, discharge and stitch abscess. Routine investigations were done as per protocol. Wound swabs were taken for culture and sensitivity. Results: The study was carried out on 200 clean cases (general and gynecological). They were 130 females and 70 males. The 100 cases whose wounds were washed with normal saline only 1 patient developed wound infection while in the other group who did not had saline irrigations 8 patients out of 100 developed wound infection. The commonest infective organisms were staphylococcus aureus and the other organisms were streptococcus pyogenes, proteus, Klaebsiella, E coli and pseudomonas. No MRSA was detected. Conclusion: In our study washing the wound with warm normal saline for 60 seconds resulted in the wound being infection free. Wound infection is associated with delayed wound healing, prolonged hospital stay and increased economic pressure on the patient and on the state. (author)

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

    Directory of Open Access Journals (Sweden)

    Piagnani M Claudia

    2010-02-01

    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

    Women having cesarean section have a high risk of wound complications. Our objective was to determine whether high transverse skin incisions are associated with a reduced risk of cesarean wound complications in women with BMI greater than 40. A retrospective cohort study was undertaken of parturients ages 18-45 with BMI greater than 40 having high transverse skin incisions from January 2010 to April 2015 at a tertiary maternity hospital. Temporally matched controls had low transverse skin incisions along with a BMI greater than 40. The primary outcome, wound complication, was defined as any seroma, hematoma, dehiscence, or infection requiring opening and evacuating/debriding the wound. Secondary outcomes included rates of endometritis, number of hospital days, NICU admission, Apgar scores, birth weight, and gestational age at delivery. Analysis of outcomes was performed using two-sample t-test or Wilcoxon rank-sum test for continuous variables and Fisher's exact test for categorical variables. Thirty-two women had high transverse incisions and were temporally matched with 96 controls (low transverse incisions). The mean BMI was 49 for both groups. There was a trend toward reduced wound complications in those having high transverse skin incisions, but this did not reach statistical significance (15.63% versus 27.08%, p = .2379). Those having high transverse skin incisions had lower five minute median Apgar scores (8.0 versus 9.0, p = .0021), but no difference in umbilical artery pH values. The high transverse group also had increased NICU admissions (28.13% versus 5.21%, p = .0011), and early gestational age at delivery (36.8 versus 38.0, p = .0272). High transverse skin incisions may reduce the risk of wound complications in parturients with obesity. A study with more power should be considered.

In accordance with the TIME principles, debridement can help remove nonviable tissue, control inflammation or infection, decrease excess moisture, and stimulate a nonadvancing wound edge. There are many types of debridement, each with a set of advantages and disadvantages that must be clearly understood by the healthcare team. Failure to use the correct debridement method for a given type of wound may lead to further delays in healing, increase patient suffering, and unnecessarily increase the cost of care. This review article discusses the various methods of debridement, describes currently available debriding agents, evaluates the clinical data regarding their efficacy and safety, and describes strategies for the management of problematic nonhealing wounds.

    This article investigates the application values of Xenogenic (porcine) acellular dermal matrix (XADM) in preparation of a Fournier gangrene wound bed. Thirty-six consecutive cases of patients with Fournier gangrene between 2002 and 2012 were enrolled in our department of our hospital. The patients were divided into two groups according to different methods of wound bed preparation after surgical débridement, including the experimental group (17 cases) and the control group (19 cases). The wounds in the experimental group were covered with XADM after surgical wound débridement, whereas the wounds were cleaned with hydrogen peroxide and sodium hypochlorite solution (one time/day) in the control group. The wound bed preparation time and hospital stay were then compared in the two groups. The wound preparation time was 13.64 ± 1.46 days and hospitalization period was 26.06 ± 0.83 days in the experimental XADM group. In the control group, the wound bed preparation time and hospitalization period were 22.37 ± 1.38 and 38.11 ± 5.60 days, respectively. The results showed statistical differences between these two groups. When used in wound débridement after Fournier gangrene, XADM protects interecological organizations, promotes the growth of granulation tissues, and maximally retains function and morphology of the perineum and penis.

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

    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.

    In experiment on 30 corpses of adult people criteria of an operational wound (depth of a wound, a corner of operational action, an axis of operational action, a corner of an inclination of operational action) were studied at preauricularis, intrauricularis, intrauriculo-temporalis and posterior mandibullaris access to temporo-mandibular joint (TMJ). New surgical intrauriculo-temporalis access to the joint is substantrated. On the basis of the analysis of 289 operations at 268 patients the indications to a choice of surgical access were developed at various diseases and damages of TMJ.

    Previous studies suggest that semicircular canal dehiscences (SCDs) have a developmental origin. We hypothesized that if SCDs originate during development, incidence of radiographic SCDs in young children will be higher than in adults. Thirty-four temporal bone HRCTs of children younger than 2 years and 40 temporal bone HRCTs of patients older than 18 years were reformatted and re-evaluated for presence of SCD or canal thinning. Results were compared with indications for HRCT and clinical information. SCDs were detected in 27.3% of children younger than 2 years of age (superior, 13.8%; posterior, 20%) and in 3% of adults (P < 0.004). Of children with one radiographic dehiscence, 55.6% had multiple and 44% had bilateral SCDs on HRCT. No lateral canal SCDs were present. Thinning of bone overlying the semicircular canals was found in 44% of children younger than 2 years and 2.5% of adults (P < 0.0001). SCDs are more common on HRCTs of very young children. This supports the hypothesis that SCDs originate from discontinuation of bone deposition/maturation. However, SCDs on imaging do not necessarily correlate with canal dehiscence syndrome and should therefore be interpreted carefully. (orig.)

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

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

    Biological soft tissues exhibit non-linear complex properties, the quantification of which presents a challenge. Nevertheless, these properties, such as skin anisotropy, highly influence different processes that occur in soft tissues, for instance wound healing, and thus its correct identification and quantification is crucial to understand them. Experimental and computational works are required in order to find the most precise model to replicate the tissues' properties. In this work, we present a wound healing model focused on the proliferative stage that includes angiogenesis and wound contraction in three dimensions and which relies on the accurate representation of the mechanical behavior of the skin. Thus, an anisotropic hyperelastic model has been considered to analyze the effect of collagen fibers on the healing evolution of an ellipsoidal wound. The implemented model accounts for the contribution of the ground matrix and two mechanically equivalent families of fibers. Simulation results show the evolution of the cellular and chemical species in the wound and the wound volume evolution. Moreover, the local strain directions depend on the relative wound orientation with respect to the fibers.

    Vacuum-assisted wound closure (VAC) therapy may heal wounds faster than conventional dressings after surgical debridement of perivascular groin infections after vascular surgery. Patients with deep infected wounds (Szilagyi grade III) were surgically revised and left open for secondary healing, then randomized to either VAC or alginate (Sorbalgon) therapy, between February 2007 and November 2011. To test the hypothesis, it was calculated that 42 patients needed to be included (90% power, 5% level of significance). It was decided to perform an interim analysis after inclusion of 20 patients. Among 66 patients undergoing groin revision, 20 patients were included in this study. Patients were randomized to VAC (n = 10) or alginate (n = 10). The two groups were comparable in patient and wound characteristics. Time to full skin epithelialization was significantly shorter in the VAC group (median, 57 days) compared with the alginate group (median, 104 days; P = .026). The number of positive wound cultures of bacteria and C-reactive protein values decreased equally in both groups between surgical revision and day 21. One femur amputation was performed in each group as a consequence of the groin infection, one patient died during the in-hospital stay in the alginate group, and none died in the VAC group. VAC achieves faster healing than alginate therapy after wound debridement for deep perivascular wound infections in the groin after vascular surgery. This finding does not allow further inclusion of patients from an ethical point of view, and this study was, therefore, stopped prematurely. Copyright © 2014 Society for Vascular Surgery.

    The use of fat grafting as a reconstructive surgical option is becoming much more common. Adipose-derived stem cells found in fat grafts are believed to facilitate wound healing via differentiation into fibroblasts and keratinocytes and the release of pro-healing growth factors. Several small studies have shown a positive effect of fat grafting in healing of wounds of a variety of aetiologies. When fat is combined with autologous platelet-rich plasma (PRP), there may be enhanced healing effects. This may be due to the pro-angiogenic and anti-inflammatory effects of PRP. We aim to synthesise the current evidence on combination fat grafting and PRP for wound healing to establish the efficacy of this technique. We will conduct a comprehensive literature search in the MEDLINE, EMBASE, CENTRAL, Science Citation Index, and Google Scholar databases (up to July 2017) to identify studies on fat grafting and PRP for wound healing. All primary studies and systematic reviews of these studies will be included, except case reports and case series with fewer than three patients, to evaluate the outcome of fat grafting and PRP on wound healing either on its own or when compared to other studies. Primary outcome measures are expected to be the proportion of total wounds healed at 12 weeks and the average wound healing time (time for 100% re-epithelialisation). Expected secondary outcome measures are the proportion of wounds achieving 50% wound healing, the type of wound benefitting most from fat grafting, economic evaluation, health-related quality of life, and adverse events. Subgroup analysis will be performed for the proportions of wounds healed based on wound aetiology. This review will provide robust evidence of the efficacy of fat grafting and PRP for wound healing. This is an emerging technique, and this review is expected to guide clinical practice and ongoing research aimed at improving wound care. PROSPERO CRD42016049881.

    The open abdomen (OA) surgical technique has become an option for treating complex abdominal injuries; however, complications leading to late closure conditions might arise. In these cases the wound must be left open, which greatly impacts the patient's life. The author aims to describe the experiences of individuals with a chronic OA wound. Qualitative design using grounded theory was utilized. This study was carried out with a group of 28 adults who were treated with OA technique and whose wound had remained open for more than a month in duration and only received outpatient wound care. Data were collected through open interviews and examined under continuous comparison. The average age of the respondents was 45 years, and their wound, treated with OA due to severe abdominal infection, remained open between 2 months and 8 years. An emergent theory was developed to describe how people facing this experience undergo a process of 4 stages: 1) finding an OA wound upon waking, 2) feeling desperate about the healing process and the limitations involved, 3) regaining control of their life, and 4) taking advantage of their second chance at life with an OA wound. This study provides insight for nurses and other health care professionals into the experiences of patients with a chronic OA wound and proposes an emerging theory based on the conceptualization of these experiences.

    Psychological stress has been shown to be an influential factor on the rate of wound healing; however these findings have been demonstrated predominantly on artificially created wounds. Due to the absence of major co-morbidities, living kidney donors are a unique group in which to study this relationship. This study investigated the effect of preoperative stress and personality on surgical wound healing through the use of high-resolution ultrasound. Living kidney donors due to undergo a hand-assisted laparoscopic donor nephrectomy were asked to complete the Perceived Stress Scale, the Life Orientation Test-Revised and the Ten Item Personality Inventory prior to surgery. High-resolution ultrasound scans of surgical wounds were performed on the first three post-operative days and once following discharge (mean=15.3 days; s.d. 2.8). Two measurements from each image were obtained: wound width (size of wound) and median intensity (a marker of tissue fluid). Latent Growth Curve Models (LGCMs) were used to evaluate wound healing. 52 living kidney donors participated. Higher pre-operative life stress, lower optimism and lower conscientiousness were associated with delayed wound healing in living kidney donors for both outcomes. Increased emotional stability was associated with faster wound healing as demonstrated by a change in median intensity. Possible confounding factors, such as age, BMI, smoking status, local anaesthetic use and wound drain placement were not influential. This study, which measured wound healing in a novel patient sample using a novel technique, has demonstrated a negative association between stress and wound healing and the positive influence of optimism, conscientiousness and emotional stability.

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

    Successful wound healing depends on various factors, including exudate control, prevention of microbial contaminants, and moisture balance. We report two cases of managing burn wounds with SMARTPORE Technology polyurethane foam dressing. In Case 1, a 2-year-old Asian girl presented with a delayed (11 days) wound on her right leg. She sustained a thermal injury from a hot iron that was left idle on the floor. Clinical inspection revealed an infected wound with overlying eschar that traversed her knee joint. As her parents refused surgical debridement under general anesthesia, hydrotherapy and wound dressing using SMARTPORE Technology Polyurethane foam were used. Despite the delay in presentation of this linear thermal pediatric burn injury that crossed the knee joint, the patient's response to treatment and its outcome were highly encouraging. She was cooperative and tolerated each dressing change without the need of supplemental analgesia. Her wound was healed by 24 days post-admission. In Case 2, a 25-year-old Asian man presented with a mixed thickness thermal flame burn on his left leg. On examination, the injury was a mix of deep and superficial partial thickness burn, comprising approximately 3% of his total body surface area. SMARTPORE Technology polyurethane foam was used on his wound; his response to the treatment was very encouraging as the dressing facilitated physiotherapy and mobility. The patient rated the pain during dressing change as 2 on a scale of 10 and his pain score remained the same in every subsequent change. His wound showed evidence of epithelialization by day 7 post-burn. There were no adverse events reported. Managing burn wounds with SMARTPORE Technology polyurethane foam resulted in reduced pain during dressing changes and the successful healing of partial and mixed thickness wounds. The use of SMARTPORE Technology polyurethane foam dressings showed encouraging results and requires further research as a desirable management option in

    Sponges are commonly used in veterinary practice. Uses for sponges in the operative arena include hemostasis, retraction, protection, dissection, and general wound management. Blood loss can be quantitated by counting blood-soaked sponges. Complications may arise when sponges are retained in the patient. Sponge retention is a risk whenever sponges are used during surgery, regardless of surgical procedure. This article reviews physical characteristics and proper uses of sponges, complications of sponge retention, and techniques to avoid retained sponges.

    Restoration of tissue integrity is essential for host defense and protection of the organism. The efficacy and quality of skin repair varies significantly over a person's lifetime. Whereas prenatal wound healing is characterized by regeneration and scarless healing, scarring, fibrosis, and loss of function are features of postnatal repair. In fact, aging is the prominent risk factor for chronic wounds, skin fragility, infections, comorbidities, and decreased quality of life. Current strategies for restoration of tissue integrity and wound therapy are not sufficient and require further investigation of the underlying pathomechanisms and the development of causal-based concepts.

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

    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.

    Left ventricular outflow tract (LVOT) pseudoaneurysm is a rare but potentially lethal complication, mainly after aortic root endocarditis or surgery. Usually it originates from a dehiscence in the mitral-aortic intervalvular fibrosa and it arises posteriorly to the aortic root. Due to these anatomical features, its imaging assessment is challenging and surgical repair requires complex procedures. An unusual case of LVOT pseudoaneurysm is described. It was detected by transthoracic ecocardiography 7 months after aortic root replacement for acute endocarditis. Multidetector computed tomography (MDCT) confirmed the presence of a pouch located between the aortic root and the right atrium. Computed tomography also detected the origin of the pseudoaneurysm from the muscular interventricular septum of the LVOT, rather below the aortic valve plane. It was repaired with an extracardiac surgical approach, sparing the aortic root bioprosthesis previously implanted. The high-resolution three-dimensional details provided by the preoperative MDCT allowed us to plan a simple and effective surgical strategy.

    This aimed to evaluate the prevalence and extent of bilateral sigmoid sinus dehiscence (SSD) and to explore the presence of idiopathic intracranial hypertension (IIH) in patients with unilateral pulsatile tinnitus (PT) with CTA/V. Sixty PT patients (52 females; 40.4 ± 11.6 years [20-72]) who underwent CTA/V and 30 non-PT patients (27 females; 38.4 ± 14.7 years [12-62]) were enrolled in this study. The primary outcome measure was the radiographic presence of SSD. The index of transverse sinus stenosis (ITSS) was obtained by multiplying the stenosis scale values for each transverse sinus, and once was ≥ 4, the presence of IIH was suspected. The prevalence and extent of SSD on symptomatic side (78%; maximum transverse diameter, MTD 0.49 ± 0.23; maximum vertical diameter, MVD 0.50 ± 0.26 cm) were significantly higher and larger than those on asymptomatic side (50%, P < 0.001; MTD 0.35 ± 0.18, P = 0.006; MVD 0.30 ± 0.15 cm, P < 0.001) in the study group and those (20%, P < 0.001; MTD 0.36 ± 0.18, P = 0.073; MVD 0.30 ± 0.22 cm, P < 0.048) in the control group. The presence of SSD showed significant correlation with both PT (logistic regression analysis, OR 4.167 [1.450-11.97]; P = 0.008) and suspected IIH (OR 16.25 [1.893-139.5]; P = 0.011). In PT patients, SSD has a significant correlation with PT and a potential correlation with IIH. (orig.)

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

    Full Text Available 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.

    To determine if In-111-WBCs scintigraphy can distinguish between healing and infection in post-surgical wounds, a prospective study was performed in patients with 3-14 day old surgical incisions. Eighteen patients (11 males and 7 females) were scanned 24 hrs after injection of 0.5 mCi of In-111 labeled autologous leukocytes. The scan findings were correlated with blood and/wound cultures results and diagnosis at time of discharge. Incisional uptake of In-111-WBCs was noted in 9 patients with infected surgical wounds and was absent in those 9 patients with non-infected surgical wounds. The results of the authors' study show that In-111-WBCs do not accumulate in non-infected surgical incisions. This confirms their previous findings in rats. The high specificity of In-111 leukocytes imaging makes it a valuable study in the evaluation of post-operative patients with suspected surgical wound infections. In-111 WBCs scintigraphy can distinguish between normal healing and infection at the site of recent (3-14 days) surgical incisions

    INTRODUCTION Wound ooze is common following total knee arthroplasty (TKA) and persistent wound infection is a risk factor for infection, and increased length and cost of hospitalisation. PATIENTS AND METHODS We undertook a prospective study to assess the effect of tourniquet time, peri-articular local anaesthesia and surgical approach on wound oozing after TKA. RESULTS The medial parapatellar approach was used in 59 patients (77%) and subvastus in 18 patients (23%). Peri-articular local anaesthesia (0.25% Bupivacaine with 1:1,000,000 adrenalin) was used in 34 patients (44%). The mean tourniquet time was 83 min (range, 38–125 min). We found a significant association between cessation of oozing and peri-articular local anaesthesia (P = 0.003), length of the tourniquet time (P = 0.03) and the subvastus approach (P = 0.01). CONCLUSIONS Peri-articular local anaesthesia, the subvastus approach and shorter tourniquet time were all associated with less wound oozing after total knee arthroplasty. PMID:20836920

    Debridement is a basic necessity to induce the functional process of tissue repair, especially in chronic wounds. In this pilot study the authors used a new debrider technology with specific monofilament fibres in a unique texture to evaluate its efficacy, safety and tolerability. In eleven patients, exhibiting all types of wound-associated debris (biofilms, slough, necrotic crusts and hyperkeratotic plaques), the debrider, wetted with physiological solution, was wiped without specific force over the wound for about 2-4 minutes. This led to removal of almost all debris leaving healthy granulation tissue intact, including small epithelialized islands of vital tissue. The procedure was without pain and adverse events. Scanning electron microscopic analyses identified the majority of the removed debris tightly packed within the monofilament texture. A surgeon who blindly assessed pictures taken before and after the debridement categorized all except one wound without the need for surgical debridement and ranked all the debridement results with the new debrider as 'very good' (best category). This formulates the basic concept that the new debrider-based technology is easy, fast, highly efficient, well tolerated and cost effective.

    Deep sternal wound infection is a life-threatening complication after cardiac surgery. The aim of this study was to investigate the factors leading to mortality, and to explore wound management techniques on deep sternal wound infection after coronary artery bypass surgery. Between 2008 and 2013, 58 patients with deep sternal wound infection were analyzed. Risk factors for mortality and morbidity including age, gender, body mass index, smoking status, chronic renal failure, hypertension, diabetes, and treatment choice were investigated. In this study, 19 patients (32.7%) were treated by primary surgical closure (PSC), and 39 patients (67.3%) were treated by delayed surgical closure following a vacuum-assisted closure system (VAC). Preoperative patient characteristics were similar between the groups. Fourteen patients (24.1%) died in the postoperative first month. The mortality rate and mean duration of hospitalization in the PSC group was higher than in the VAC group (P = .026, P = .034). Significant risk factors for mortality were additional operation, diabetes mellitus, and a high level of EuroSCORE. Delayed surgical closure following VAC therapy may be associated with shorter hospitalization and lower mortality in patients with deep sternal wound infection. Additional operation, diabetes mellitus, and a high level of EuroSCORE were associated with mortality.

    The aim of the study was to assess the clinical outcomes of surgical repair of uterine cesarean scar defects with sonography (US). Seven nonpregnant women with history of cesarean section and a large uterine scar defect were enrolled. The surgical repair was performed by minilaparotomy. The US assessment of the uterine scar was performed using a standardized approach at baseline, then at a first visit 2-3 days following the surgical intervention (V1) and at a follow-up visit 3 months later (V2). Residual myometrial thickness (RMT), width, and depth of the scar defect were measured. The mean RMT increased significantly from 1.9 mm at baseline to 8.8 mm at V1 and 8.0 mm at V2. No intraoperative complications were observed. Postmenstrual spotting and abdominal pain reported preoperatively resolved after the operation. A surgical repair procedure for an incompletely healed uterine cesarean scar is effective in increasing RMT thickness, decreasing the depth of the scar, and reducing symptoms related to the cesarean section scar defect. Further studies on post-repair pregnancy outcomes are required to evaluate whether the procedure affects the rate of cesarean scar pregnancy, morbidly adherent placenta, and/or uterine scar dehiscence and rupture. The repair of a cesarean scar defect is recommended only for symptomatic women. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:455-460, 2017. © 2017 Wiley Periodicals, Inc.

    Full Text Available Background: While many patients are admitted to hospital for treatment of infections, some acquire infection during their stay in the hospital. These infections are called as nosocomial infections. Surgical site infection or post operative wound infection is one of them. It is defined as infection of previously sterile tissue incised to gain exposure for operating deeper spaces operatively exposed or organs manipulated by a surgeon. It is one of the feared complications of surgery as it increases morbidity as well as cost of medical care. Aims and Objectives: Study was conducted to find out incidence of surgical site infection rate in surgical ward, evaluate various factors contributing to infection and to identify causative pathogens and their antibiogram patterns. Material and Methods: All clean and clean contaminated operative cases admitted in surgery ward in study period of 18 months were included. Preoperative, operative and postoperative management protocols of the cases were recorded in detail. Results: A total of 1082 operated cases were studied among which 59 infected cases were found. Surgical Site Infection (SSI rate was 5.45%. E. coli and St
