Penetrating abdominal injuries have been traditionally managed by routine laparotomy. New understanding of trajectories, potential for organ injury, and correlation with advanced radiographic imaging has allowed a shift towards non-operative management of appropriate cases. Although a selective approach has been established for stab wounds, the management of abdominal gunshot wounds remains a matter of controversy. In this chapter we describe the rationale and methodology of selecting patients for non-operative management. We also discuss additional controversial issues, as related to antibiotic prophylaxis, management of asymptomatic thoracoabdominal injuries, and the use of colostomy vs. primary repair for colon injuries.

MR imaging was found to be the most sensitive modality for the detection of spinal cord abnormalities in the acutely injured spine. Although it is reported that traumatic pneumomyelogram indicates a base-of-skull or middle cranial fossa fracture and is almost certainly associated with intracranial subarachnoid air, early MR imaging may demonstrate subarachnoid air in penetrating trauma of the spinal cord without head injury. We report two cervical-spine stab-wound cases, one of which had subarachnoid air on early MR findings. (orig.)

We devised a protocol to prospectively manage stab wounds to the back with the hypothesis that the triple contrast computed tomographic (CT) scan is an effective means of detecting occult injury in these patients. All wounds to the back in hemodynamically stable adults were locally explored. All patients with muscular fascial penetration underwent triple contrast CT scanning utilizing oral, rectal, and IV contrast. Patients did not undergo surgical exploration if their CT scan was interpreted as negative or if the CT scan demonstrated injuries not requiring surgical intervention. Fifty-three patients were entered into the protocol. The time to complete the triple contrast CT scan ranged from 3 to 6 hours at a cost of $1050 for each scan. In 51 patients (96%), the CT scan either had negative findings (n = 31) or showed injuries not requiring exploration (n = 20). These patients did well with nonsurgical management. Two CT scans documented significant injury and led to surgical exploration and therapeutic celiotomies. Although triple contrast CT scanning was able to detect occult injury in patients with stab wounds to the back it did so at considerable cost and the results rarely altered clinical care. Therefore, its routine use in these patients is not recommended.

The optimal management of stable patients with anterior abdominal stab wounds (AASWs) remains a matter of debate. A recent Western Trauma Association (WTA) multicenter trial found that exclusion of peritoneal penetration by local wound exploration (LWE) allowed immediate discharge (D/C) of 41% of patients with AASWs. Performance of computed tomography (CT) scanning or diagnostic peritoneal lavage (DPL) did not improve the D/C rate; however, these tests led to nontherapeutic (NONTHER) laparotomy (LAP) in 24% and 31% of cases, respectively. An algorithm was proposed that included LWE, followed by either D/C or admission for serial clinical assessments, without further imaging or invasive testing. The purpose of this study was to evaluate the safety and efficacy of the algorithm in providing timely interventions for significant injuries. A multicenter, institutional review board-approved study enrolled patients with AASWs. Management was guided by the WTA AASW algorithm. Data on the presentation, evaluation, and clinical course were recorded prospectively. Two hundred twenty-two patients (94% men, age, 34.7 years ± 0.3 years) were enrolled. Sixty-two (28%) had immediate LAP, of which 87% were therapeutic (THER). Three (1%) died and the mean length of stay (LOS) was 6.9 days. One hundred sixty patients were stable and asymptomatic, and 81 of them (51%) were managed entirely per protocol. Twenty (25%) were D/C'ed from the emergency department after (-) LWE, and 11 (14%) were taken to the operating room (OR) for LAP when their clinical condition changed. Two (2%) of the protocol group underwent NONTHER LAP, and no patient experienced morbidity or mortality related to delay in treatment. Seventy-nine (49%) patients had deviations from protocol. There were 47 CT scans, 11 DPLs, and 9 laparoscopic explorations performed. In addition to the laparoscopic procedures, 38 (48%) patients were taken to the OR based on test results rather than a change in the patient's clinical

We sought to determine the effect of postmortem ventilation in combination with a suction pump in cases showing penetrating trauma to the chest with haemo- and/or pneumothorax, for better evaluation of the lungs in postmortem computed tomography (PMCT). The study included 6 subjects (1 female, 5 male; age 32-67years) with a penetrating gunshot or stab wound to the chest and consecutive pneumo- and/or haemothorax. The pneumo- and haemothorax were evacuated by a suction pump, and postmortem ventilation was applied using a home care ventilator. PMCT images with and without postmortem ventilation were compared, as well as the autopsy results. In three cases haemo- and pneumothorax was clearly reduced. Postmortem ventilation led to distinct re-expansion of the lungs in two cases, and to re-expansion of single lung lobes in two cases with shotgun injuries. No visible effect was seen in the remaining two cases, because of extensive destruction of lung tissue and blood aspiration. In two cases the injuries sustained in the individual lung lobes were successfully located during postmortem ventilation. The bullet channel was apparent in one case; in another case, injury of the pericardium became visible by generating pneumopericardium. The present method is capable of improving evaluation of the postmortem lung in the presence of single stab or gunshot wounds and if there is no severe destruction of the respiratory system and aspiration. Forensic autopsy should still be considered as the gold standard, although in some cases the present method might be helpful, especially where no autopsy is required.

Abdominal trauma

Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

Fatalities due to attacks by tigers on humans are uncommon and are rarely described in the medico-legal literature. We herein present a forensic investigation in a unique case of a fatal tiger attack in the wild on a 35 year old female in India by an Indian Bengal tiger (Panthera tigris tigris). The attack resulted in two pairs of puncture wounds over the nape area with occult cervical spine injuries resulting from transfixing of spine due to the tiger canines; multiple puncture wounds, numerous scratches and abrasions consistent with the tiger claw injuries and injury to the right jugulocarotid vessels. This case outlines the characteristic injury pattern from such an attack along with the multiple sources of the tiger injuries. The analysis of these injuries might reveal the motivation behind the attack and the big cat species involved in the attack. A tiger injury is sometimes compared with a stab injury, as the patterned injuries due to a tiger bite are characterized by multiple penetrating, stab-like wounds. So, a special attention is paid toward establishment of the cause of death from bites by the animal teeth under unknown circumstances of trauma and to exclude the possibility of a homicide beyond reasonable doubt in such cases.

Full Text Available ABSTRACT Objective: to evaluate the epidemiological profile of deaths due to abdominal trauma at the Forensic Medicine Institute of Belo Horizonte, MG - Brazil. Methods: we conducted a retrospective study of the reports of deaths due to abdominal trauma autopsied from 2006 to 2011. Results: we analyzed 1.888 necropsy reports related to abdominal trauma. Penetrating trauma was more common than blunt one and gunshot wounds were more prevalent than stab wounds. Most of the individuals were male, brown-skinned, single and occupationally active. The median age was 34 years. The abdominal organs most injured in the penetrating trauma were the liver and the intestines, and in blunt trauma, the liver and the spleen. Homicide was the most prevalent circumstance of death, followed by traffic accidents, and almost half of the cases were referred to the Forensic Medicine Institute by a health unit. The blood alcohol test was positive in a third of the necropsies where it was performed. Cocaine and marijuana were the most commonly found substances in toxicology studies. Conclusion: in this sample. there was a predominance of penetrating abdominal trauma in young, brown and single men, the liver being the most injured organ.

This review of special literature encompasses the publications on the injuries inflicted by piercing objects. The results of analysis of these materials indicate that both the mechanisms of formation and the morphological features of stab wounds and damages to the clothes are studied perfectly well. Their shape and morphological patterns are shown to be dependent on the size, shape, and cross-section area of the great variety of the piercing objects. However, investigations carried out thus far did not take into consideration the formation of the signs of skin plastic deformation, such as edge portions of borderline thickening, stretching of epidermis over the walls, transformation of the epidermal network pattern into longitudinal folding, etc. It is concluded that further studies are necessary to better characterize injuries inflicted by piercing objects differing in the sharpness and the shape of cross section and thereby to obtain a deeper insight in the morphological features. It can be expected that such studies will provide a basis for the development of criteria for the individual and intra-group expert identification of the traumatic agents.

Stab injuries and fatalities have been reported to be the most common crimes of violence in several countries, particularly in those where access to firearms is restricted [J.M. Taupin, F.-P.

The authors analyse clinical cases of penetrating thoracic, abdominal, perineal and anorectal injury and describe the traumatic event and type of lesion, the principles of surgical treatment, the complication rate and follow up. In the last 24 months, we analyzed 10 consecutive cases of penetrating thoracic and abdominal wounds [stab wound (n=7), with evisceration (n=4), gunshot wound (n=1)], and penetrating perineal and anorectal wounds (impalement n=4). In addition, we report an unusual case of neck injury from a stab wound. All the patients underwent emergency surgery for the lesions reported. In 7 cases of perforating vulnerant thoracoabdominal trauma from stab wounds there was hemoperitoneum due to bleeding from the abdominal wall (n=3), the omentum (n=1), the vena cava (n=1) and the liver (n=2). Evisceration of the omentum was observed in 4 cases. In 2 cases laparoscopy was performed. In one case laparotomy and thoracoscopy was performed. In a patient with an abdominoperineal gunshot wound, exploration was extraperitoneal. The 4 cases of perineal and anorectal impalement were treated with primary reconstruction, while in one case a laparotomy was needed to suture the rectum and fashion a temporary colostomy. In one case of anorectal injury rehabilitation resulted in a gradual improvement of fecal continence, while in the patient with the colostomy follow up at 2 months was scheduled to plan colostomy closure. Based on the our clinical experience and the literature, in penetrating abdominal trauma laparotomy may be required if patients are hemodynamically unstable (or in hemorrhagic shock), in patients with evisceration and peritonitis, or for exploration of penetrating thoracoabdominal and epigastric lesions. In anterior injuries of the abdominal wall from gunshot or stab wounds, laparotomy is indicated when there is peritoneal violation and significant intraperitoneal damage. In patients with actively bleeding wounds of the abdominal wall muscles minimal

Introduction Vacuum-assisted closure (VAC) is useful for treating complex wounds because it promotes granulation. In the present report, a successful case of VAC used for an open abdominal wound with enterocutaneous fistulae after multiple intestinal perforations during chemotherapy is described. Presentation of case A 73-year-old man was admitted to our hospital with severe abdominal pain. He underwent surgical resection for ascending colon cancer 4 years ago and was administered chemotherapy with bevacizumab for recurrence. Physical examination and computed tomography revealed perforation of the intestine, and an emergency operation was performed. Following this procedure, other intestinal perforations occurred, resulting in an open abdominal wound at postoperative day (POD) 10. To isolate enteric contents and promote granulation, VAC was applied to the abdominal wound with enterocutaneous fistulae. Oral intake started at POD 21 and the wound size became smaller. Further, an ostomy bag was directly attached to the most oral perforation site. The patient recovered from life-threatening events without severe infection and was transferred to another hospital close to his home at POD 180. Discussion Gastrointestinal perforation is known to be one of the fatal adverse events of bevacizumab. In this case four gastrointestinal perforations were observed. Isolation of enteric contents is important to heal the wound and VAC is an effective therapy for the management of open abdominal wounds even with enterocutaneous fistulae. Conclusion Innovative VAC use for the management of open abdominal wounds can improve the nutritional status and overall wound healing of the patient. PMID:26599504

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

Introduction In light of continuing controversy surrounding the management of penetrating colonic injuries, we set out to compare the outcome of penetrating colonic trauma according to whether the mechanism of injury was a stab wound or a gunshot wound. Methods Our trauma registry was interrogated for the 5-year period from January 2012 to December 2016. All patients over the age of 18 years with penetrating trauma (stab or gunshot) and with intraoperatively proven colonic injury were reviewed. Details of the colonic and concurrent abdominal injuries were recorded, together with the operative management strategy. In-hospital morbidities were divided into colon-related and non-colon related morbidities. The length of hospital stay and mortality were recorded. Direct comparison was made between patients with stab wounds and gunshot wounds to the colon. Results During the 5-year study period, 257 patients sustained a colonic injury secondary to penetrating trauma; 95% (244/257) were male and the mean age was 30 years. A total of 113 (44%) sustained a gunshot wound and the remaining 56% (144/257) sustained a stab wound. Some 88% (226/257) of all patients sustained a single colonic injury, while 12% (31/257) sustained more than one colonic injury. A total of 294 colonic injuries were found at laparotomy. Multiple colonic injuries were less commonly encountered in stab wounds (6%, 9/144 vs. 19%, 22/113, P colonic stab wounds and colonic gunshot wounds are different in terms of severity of the injury and in terms of outcome. While primary repair is almost always applicable to the management of colonic stab wounds, the same cannot be said for colonic gunshot wounds. The management of colonic gunshot wounds should be examined separately from that of stab wounds.

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.

Objective: To observe the change of endotoxin (lipopolysaccharide, LPS), tumor necrosis factor-α (TNF-α), IL-6, IL-8 in plasma in rats with open abdominal wound and seawater immersion. Method: One hundred and sixteen adult Wistar rats were randomly divided into 2 groups, ninety-six in the group of open abdominal wound with seawater immersion and 20 in open abdominal wound group (control group). LPS, TNF-α, IL-6 and IL-8 in plasma were examined at 0.5 h, 1 h, 2 h, 3 h and 4 h after open abdominal wound and seawater immersion by rapid microorganism-testing device and gamma detectors. All data were analyzed with statistic software. Results: Compared with the control group, the LPS level in plasma increased with significantly 2-4 hours after the open abdominal wound with seawater immersion (P<0.05), the concentrations of TNF-α significantly increased 4 hours after seawater immersion, and the IL-6 concentrations significantly increased 3-4 hours after seawater immersion. There was no statistical difference in IL-8 concentrations between the two groups. Conclusion: Closely related to the injury, the marked increase in LPS, TNF-α and IL-6 in plasma is one of the main fetal causes of toxic shock. (authors)

Purpose: Abdominal scars may impair healing after abdominoplasty. We aimed to determine whether right subcostal or upper midline scars led to increased wound healing problems. Methods and Materials: Review of all patients who had abdominoplasty from March 1998 to February 2008 was performed. Variables studied included age, gender, body mass index (BMI), medical history, and postoperative complications. Statistical analysis was performed in Stata SE, version 10.

2008-02-01

Full Text Available Background:There are a large number of patients with penetrating abdominal trauma who have normal vital signs and negative abdominal examination when referred to trauma centers. Agreat deal of controversy exists between authorities about screening these patients for emergency explorative laparotomy. Many references have reported more than 90% sensitivity for DPL as a diagnostic method to determine whether intraabdominal injuries were present and emergent laparotomy is indicated or not. This study is for reassignment of this sensitivity according to our own evidence. Methods: All of the patients with abdominal stab wounds and normal vital signs plus negative abdominal examination who were referred to Shohada-e-Tajrish hospital between March 2004 to December 2005, underwent local wound exploration and those confirmed to have peritoneal penetration, underwent emergency laparotomy. In the operating room and prior to surgery, under general anesthesia, DPL was performed. Then DPL results were compared with laparotomy findings and DPL sensitivity was assigned. Results: Of the total number of 34 patients, 8 had a positive DPL and positive laparotomy; 2 had a positive DPL and negative laparotomy; 8 had negative DPL and positive laparotomy, and 16 patients had negative DPL and negative laparotomy. Conclusion: According to our study, DPL sensitivity is much less than mentioned in trauma texts (approximately 50%. So, it is not a valuable tool to discriminate between operative and conservative approaches in penetrating abdominal trauma. We suggest more sensitive modalities. Laparotomy is the most sensitive approach but at the price of a high negative laparotomy rate.

The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

Incineration or extensive burning of the body, causing changes in the content and distribution of fluids, fixation and shrinking processes of tissues, can alter the typical macroscopic and microscopic characteristics of firearm wounds, hampering or at least complicating the reconstruction of gunshot fatalities. The present study aims at evaluating the potential role of micro-computed tomography (micro-CT) for detecting and quantifying gunshot residue (GSR) particles in experimentally produced intermediate-range gunshot wounds severely damaged by fire. Eighteen experimental shootings were performed on 18 sections of human calves surgically amputated for medical reasons at three different firing distances (5, 15 and 30 cm). Six stab wounds produced with an ice pick were used as controls. Each calf section underwent a charring cycle, being placed in a wood-burning stove for 4 min at a temperature of 400 °C. At visual inspection, the charred entrance wounds could not be differentiated from the exit lesions and the stab wounds. On the contrary, micro-CT analysis showed the presence of GSR particles in all burnt entrance gunshot wounds, while GSR was absent in the exit and stab wounds. The GSR deposits of the firearm lesions inflicted at very close distance (5 cm) were mainly constituted of huge particles (diameter >150 μm) with an irregular shape and well-delineated edges; at greater distances (15 and 30 cm), agglomerates of tiny radiopaque particles scattered in the epidermis and dermis layers were evident. Statistical analysis demonstrated that also in charred firearm wounds the amount of GSR roughly correlates with the distance from which the gun was fired. The obtained results suggest that micro-CT analysis can be a valid screening tool for identifying entrance gunshot wounds and for differentiating firearm wounds from sharp-force injuries in bodies severely damaged by fire.

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

Primary stabbing headache.

Pareja, Juan A; Sjaastad, Ottar

2010-01-01

Primary stabbing headache is characterized by transient, cephalic ultrashort stabs of pain. It is a frequent complaint with a prevalence of 35.2%, a female preponderance, and a mean age of onset of 28 years (Vågå study). Attacks are generally characterized by moderate to severe, jabbing or stabbing pain, lasting from a fraction of a second to 3s. Attack frequency is generally low, with one or a few attacks per day. The paroxysms generally occur spontaneously, during daytime. Most patients exhibit a sporadic pattern, with an erratic, unpredictable alternation between symptomatic and non-symptomatic periods. Paroxysms are almost invariably unilateral. Temporal and fronto-ocular areas are most frequently affected. Attacks tend to move from one area to another, in either the same or the opposite hemicranium. Jabs may be accompanied by a shock-like feeling and even by head movement - "jolts" -or vocalization. On rare occasions, conjunctival hemorrhage and monocular vision loss have been described as associated features. Primary stabbing headache may concur, synchronously or independently, with other primary headaches. In contrast to what is the case in adults, in childhood it is not usually associated with other headaches. Treatment is rarely necessary. Indomethacin, 75-150 mg daily, may seem to be of some avail. Celecoxib, nifedipine, melatonin, and gabapentin have been reported to be effective in isolated cases and small series of patients. The drug studies need corroboration. Copyright © 2011 Elsevier B.V.

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

2011-11-01

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

Manufacturers are aiming for more flexible and lightweight protective clothing to increase wearing comfort. A cardigan with a knitted stab-resistant inlay and an alarm system is presented. The stab-resistant inlay is based on a multilayer ultra-high molecular weight poly ethylene (UHMW-PE) fabric. Stab resistance was evaluated according to the standard of the Association of Test Laboratories for Bullet, Stab or Pike Resistant Materials and Construction Standard (VPAM 2011). Furthermore sensors for the detection of cuts and pressure were integrated. Both sensors can trigger alarms if the wearer is attacked. Normal pressure occurring through leaning on a wall or sitting is filtered out and does not trigger an alarm.

Full Text Available Objective: The aim of the present work is to analyze the differences and similarities between the elements of a conventional autopsy and images obtained from postmortem computed tomography in a case of a homicide stab wound. Method: Comparison between the findings of different methods: autopsy and postmortem computed tomography. Results: In some aspects, autopsy is still superior to imaging, especially in relation to external examination and the description of lesion vitality. However, the findings of gas embolism, pneumothorax and pulmonary emphysema and the relationship between the internal path of the instrument of aggression and the entry wound are better demonstrated by postmortem computed tomography. Conclusions: Although multislice computed tomography has greater accuracy than autopsy, we believe that the conventional autopsy method is fundamental for providing evidence in criminal investigations.

A 37 year old man was found collapsed at the roadside and taken to the emergency department. Communication was difficult, as the patient could not speak English. There was a wound in the left second intercostal space on the midclavicular line, which was bleeding and was bubbling air. A drain was inserted, bleeding controlled, and his wounds sutured. Chest x ray later confirmed satisfactory placement of the drain. The following day, swelling and discharge indicated oesophageal damage, which was later confirmed by gastrografin swallow. With conservative management in hospital for 2 weeks, he made a full recovery and was discharged.

Laparoscopy in penetrating abdominal injuries is now accepted and practiced in many modern trauma centres. However its role in evaluating and managing retroperitoneal injuries is not yet well established. The aim of this study was to document our experience in using laparoscopy in a setting of penetrating abdominal injuries with suspected retroperitoneal injury in haemodynamically stable patients. A retrospective descriptive study of prospectively collected data from a trauma unit at Dr George Mukhari Academic Hospital (DGMAH) was done. All haemodynamically stable patients with penetrating abdominal injury who were offered laparoscopy from January 2012 to December 2015 were reviewed and those who met the inclusion criteria were analysed. A total of 284 patients with penetrating abdominal injuries were reviewed and 56 met the inclusion criteria and were analysed. The median age was 30.8 years (15-60 years) and males constituted 87.5% of the study population. The most common mechanism of injury was penetrating stab wounds (62.5%). Forty-five patients (80.3%) were managed laparoscopically, of these n=16 (28.5%) had retroperitoneal injuries that required surgical intervention. The most commonly injured organ was the colon (19.6%). The conversion rate was 19.6% with most common indication for conversion been active bleeding (14%). The complication rate was 7.14% (N=4) and were all Clavien-Dindo grade 3. There were no recorded missed injuries and no mortality. The positive outcomes documented in this study with no missed injuries and absence of mortality suggests that laparoscopy is a feasible option in managing stable patients with suspected retroperitoneal injuries.

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

Objective: To assess the feasibility and safety of selective nonoperative management in penetrating abdominal solid organ injuries. Background: Nonoperative management of blunt abdominal solid organ injuries has become the standard of care. However, routine surgical exploration remains the standard practice for all penetrating solid organ injuries. The present study examines the role of nonoperative management in selected patients with penetrating injuries to abdominal solid organs. Patients and Methods: Prospective, protocol-driven study, which included all penetrating abdominal solid organ (liver, spleen, kidney) injuries admitted to a level I trauma center, over a 20-month period. Patients with hemodynamic instability, peritonitis, or an unevaluable abdomen underwent an immediate laparotomy. Patients who were hemodynamically stable and had no signs of peritonitis were selected for further CT scan evaluation. In the absence of CT scan findings suggestive of hollow viscus injury, the patients were observed with serial clinical examinations, hemoglobin levels, and white cell counts. Patients with left thoracoabdominal injuries underwent elective laparoscopy to rule out diaphragmatic injury. Outcome parameters included survival, complications, need for delayed laparotomy in observed patients, and length of hospital stay. Results: During the study period, there were 152 patients with 185 penetrating solid organ injuries. Gunshot wounds accounted for 70.4% and stab wounds for 29.6% of injuries. Ninety-one patients (59.9%) met the criteria for immediate operation. The remaining 61 (40.1%) patients were selected for CT scan evaluation. Forty-three patients (28.3% of all patients) with 47 solid organ injuries who had no CT scan findings suspicious of hollow viscus injury were selected for clinical observation and additional laparoscopy in 2. Four patients with a “blush” on CT scan underwent angiographic embolization of the liver. Overall, 41 patients (27

South Africa has very high levels of accidental trauma as well as interpersonal violence. There are more admissions for trauma in South Africa than for any other disease; therefore it can be regarded as the Number 1 disease in the country. Complex abdominal injuries are common, requiring specific management techniques. The aim is to document our experience with the Modified Sandwich Vacuum Pack technique for temporary closure of abdominal wounds. After providing a short historical overview, we will demonstrate the technique which we carefully adapted over the last decade to the present Modified Sandwich Vacuum Pack technique. In the Last 5 years we utilized our Modified Sandwich Vacuum Pack technique 153 times in 69 patients. Five (5) patients were under the age of 12 years. In the patient group over 12 years the most common indication for using our technique were penetrating injuries (40), abdominal sepsis (28), visceral edema (10), abdominal compartment syndrome (9), abdominal packs (6),Abdominal wall defects (2). In the group under 12-years the 2 children had liver ruptures (posttraumatic) and 3 liver transplantations. The average cost for the materials used with our technique was ZAR 96. (10 Euro and 41 cents). In our experience the Modified Sandwich Vacuum Pack technique is an effective, cheap methodology to deal with open abdomens in the African setting.A drawback may be the technical expertise required, particular in centers dealing with low numbers of complex abdominal trauma.

Wound edge protectors in open abdominal surgery to reduce surgical site infections: a systematic review and meta-analysis.

Directory of Open Access Journals (Sweden)

André L Mihaljevic

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. Further trials are needed to

In the trauma unit of the Bloemfontein Academic Complex, the total number of stab wounds seen represents approximately 70.5% of penetrating injuries, which is 6.4% of 5004 trauma cases seen in a period of 1 year. The other cases are gunshot wounds and pedestrian or motor vehicle accidents. Specific guidelines and protocols are followed for penetrating trauma management. All imaging modalities are utilized, with chest radiography the mainstay of thoracic imaging in patients having sustained sharp penetrating chest injuries. Computed tomography (CT) is being used more frequently as the primary imaging modality in the evaluation of hemodynamically stable patients with penetrating injuries. The improved speed of data acquisition and superior image reconstruction of multidetector CT (MDCT) has further driven this change in imaging approach. Although digital subtraction angiography (DSA) has been the reference standard for the diagnosis of traumatic vascular injuries, it is giving way to faster, less invasive, and less personnel-intensive imaging techniques, e.g., MDCT angiography. Given the fact that we work in an academic environment and that we have a dedicated interventional unit, arteriography is still frequently performed and still has its place as the 'gold standard' in the diagnosis of vascular injuries. Penetrating chest injuries suspected of traversing the mediastinum or extending near the posterior mediastinal structures dictate esophageal and tracheal evaluation. Although radiology has a role to play, direct visualization (esophagoscopy, bronchoscopy) remains the most reliable method of excluding injuries to these structures. Transthoracic ultrasound (echocardiography) has become indispensable in helping to evaluate injuries to the heart and the ascending and descending aortas. More recent work has demonstrated that ultrasonography can also be used to detect hemothoraces and pneumothoraces with accuracy

Intra-abdominal hypertension and abdominal compartment syndrome in association with ruptured abdominal aortic aneurysm in the endovascular era: vigilance remains critical.

Science.gov (United States)

Bozeman, Matthew C; Ross, Charles B

2012-01-01

Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are common complications of ruptured abdominal aortoiliac aneurysms (rAAAs) and other abdominal vascular catastrophes even in the age of endovascular therapy. Morbidity and mortality due to systemic inflammatory response syndrome (SIRS) and multiple organ failure (MOF) are significant. Recognition and management of IAH are key critical care measures which may decrease morbidity and improve survival in these vascular patients. Two strategies have been utilized: expectant management with prompt decompressive laparotomy upon diagnosis of threshold levels of IAH versus prophylactic, delayed abdominal closure based upon clinical parameters at the time of initial repair. Competent management of the abdominal wound with preservation of abdominal domain is also an important component of the care of these patients. In this review, we describe published experience with IAH and ACS complicating abdominal vascular catastrophes, experience with ACS complicating endovascular repair of rAAAs, and techniques for management of the abdominal wound. Vigilance and appropriate management of IAH and ACS remains critically important in decreasing morbidity and optimizing survival following catastrophic intra-abdominal vascular events.

Bariatric surgery patients enter into a catabolic state postoperatively, which can lead to an aberrant wound healing process. To improve the future treatment of morbidly obese patients, the aim of our study was to understand the link between bariatric surgery and alterations in the wound healing processes. A total of 18 morbidly obese Zucker rats were separated into three groups and underwent one of three surgical procedures: Roux-en-Y gastric bypass (RYGB; n = 6); sleeve gastrectomy (GS; n = 6); or midline laparotomy only (n = 6). The rats were weighed on postoperative day 0, 3, 7, and 14. On day 14, the abdominal wall was harvested and underwent histologic and biomechanical evaluation. A significant difference was found in the weight gain between the laparotomy control group (LC) and bariatric surgical groups at 7 and 14 d. By postoperative day 7, the GS and RYGB rats weighed significantly less than the LC group, losing, on average, 7% and 6% of their initial body weight, respectively, and the LC gained 4% of their weight (P gained 20% of their original weight, and the two bariatric groups both weighed significantly less (P bariatric surgery negatively affects wound healing both histologically and biomechanically compared with nonbariatric models. Although obesity remains a significant factor in the wound healing process, understanding the link between bariatric surgery and alterations in wound healing is imperative before advocating simultaneous repair of ventral hernias during concomitant bariatric surgery.

1995-01-01

A randomized study of abdominal fascial closure using interrupted polyglyconate and polyglycolic acid sutures after laparotomy was carried out in 204 consecutive patients with suspected impaired wound healing. There were no statistically significant differences between the two sutures with regard...... to the development of fascial disruption and incisional hernia. Wound infection demanding surgical intervention was found in 7 per cent of patients with polyglyconate sutures and in 16 per cent of those with polyglycolic acid sutures (P = 0.04). Monofilament polyglyconate suture does not reduce the incidence...... of fascial disruption and incisional hernia after laparotomy in patients with suspected impaired wound healing but the incidence of wound infection may be reduced compared with that of multifilament polyglycolic acid suture....

Arma branca retida em aorta abdominal superior

Directory of Open Access Journals (Sweden)

Fernando Antonio C. Spencer Netto

Full Text Available Abdominal aorta wounds carries a high immediate mortality. Few patients reach hospital care alive. There are no reports on Medline (1969-2002 about aortic wounds of foreign body with retention. A case with upper abdominal aortic wound with an inlaid blade is reported. The retained blade fixed the stomach to the surgical field, difficulting the vascular control, leading to an unconventional approach and allowing extensive contamination. The patient developed multiple organ dysfunction and died at fifth postoperative day. Singularities of an inlaid knife in upper abdominal aorta and changes in traditional approach are discussed. The authors assumed that the inlaid knife decreased the bleeding, allowing the patient arrival to the hospital, but worsened the approach to the aorta wound.

Singh, Swati; Prasad, Chandrakant

2017-01-01

Background and Aims: Local infiltration of the surgical wound is one of the important components of multimodal analgesia for post-operative pain relief. This study determines the post-operative analgesic effect of addition of dexmedetomidine to bupivacaine for local infiltration of the surgical wound. Methods: Sixty women belonging to American Society of Anesthesiologists’ Grade 1 or 2 posted for abdominal hysterectomy were randomly allocated to Group I (control group) where patients received wound infiltration with 30 mL 0.25% bupivacaine at the end of surgery, or Group II, where patients received wound infiltration with 1.0 μg/kg dexmedetomidine diluted in 30 mL 0.25% bupivacaine. The primary objective of the study was to assess post-operative pain scores. Number of patients requiring rescue analgesia and total morphine consumption during 24 h after surgery were also recorded. Statistical significance for analgesic requirement was determined by one-way analysis of variance. Results: Pain scores were lower at rest for 12 h and on cough for 6 h in Group II (<0.01). All patients in Group I required supplemental morphine compared to only 3 patients in Group II (P < 0.003). Post-operative analgesia requirement was significantly less in patients receiving dexmedetomidine in wound infiltration compared to patients receiving bupivacaine alone (P < 0.001). Conclusions: Wound infiltration of dexmedetomidine with bupivacaine provides superior pain relief compared to bupivacaine alone. PMID:28655956

Full Text Available Effect of Altitude and Wounding on Blood Disease Progress of Plantain. In the latest decade, the blood disease of banana has spread in almost all provinces in Indonesia and caused wilting of millions banana clusters in several provinces.  It is very difficult to control the disease due  to the base data about ecology and epidemiology of the pathogen are still poorly understood. This research aimed to evaluate the effect of  wounding of inoculation site on blood disease progress of plantain. The experiment was arranged using randomized completely block design It was conducted at three locations with altitude of 100, 1000, and 1600 m above sea levels as replication block. The treatments were wounding, unwounding inoculation site, inoculation, and uninoculation of plantain cv. Kepok Kuning Wounding was applied by stabbing with an injection pin around the corm of 15 stabs/seedling. The seedlings were planted singly in one liter of non sterile soil in plastic bag.  Each treatment consisted of 5 seedlings which was replicated 3 times. Inoculation was done  by soil drenching of 20 ml bacterial suspension at  concentration of 108 cfu/ml two week after planting.  The pathogen used for inoculation originated from low land area (about 100 m above sea level.  Observation was done weekly for 5 weeks. The variables observed were wilt intensity and area under disease progress (AUDPC. The results showed that blood disease was able to establish at altitude of 1600 m above sea level. The disease progress however was slower that those at 100 and 1000 m above sea level. On wounded seedling, the disease progress was more aggressive than those on unwounded one.

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.

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

The purpose of this research was to enhance the stab resistance of protective clothing material by developing a new high-density nonwoven structure. Ice picks often injure Japanese police officers due to the strict regulation of swords in the country. Consequently, this study was designed to improve stab resistance against ice picks. Most existing anti-stab protective clothing research has focused on various fabrics impregnated with resin, an approach that brings with it problems of high cost and complicated processing. Seldom has research addressed the potential for improving stab resistance by using nonwoven structures, which exhibit better stab resistance than fabric. In this research, we prepared a series of nonwoven structures with densities ranging from about 0.14 g/cm 3 to 0.46 g/cm 3 by varying the number of stacked layers of Kevlar/polyester nonwoven under a hot press. We then proposed two methods for producing such hot-press nonwovens: the multilayer hot-press method and the monolayer hot-press method. Stab resistance was evaluated according to NIJ Standard-0115.00. We also investigated the relationship among nonwoven density, stab resistance, and flexural rigidity, and here we discuss the respective properties of the two proposed methods. Our results show that stab resistance and flexural rigidity increase with nonwoven density, but flexural rigidity of nonwovens prepared using the monolayer hot-press method only shows a slight change as nonwoven density increases. Though the two methods exhibit little difference in maximum load, the flexural rigidity of nonwovens prepared using the monolayer hot-press method is much lower, which contributes to superior wear comfort. Finally, we investigated the mechanism behind the stabbing process. Stabbing with an ice pick is a complicated process that involves many factors. Our findings indicate that nonwovens stop penetration primarily in two ways: nonwoven deformation and fiber fractures.

A Retrospective Study of Blade Wound Characteristics in Suicide and Homicide.

Krywanczyk, Alison; Shapiro, Steven

2015-12-01

The distinction between self-inflicted blade wounds and blade wounds inflicted by another can be difficult in situations where there is little available history or context. We reviewed homicides and suicides in the past 10 years at the Vermont Office of the Chief Medical Examiner to define the characteristics of homicidal and suicidal blade wounds. All homicides and suicides involving blade wounds, not just those in which blade wounds were the cause of death, were included. Information regarding victim demographics, location and type of injuries, toxicology, and evidence of suicidality was gathered. Blade wounds were the cause of death in 85.7% of homicides but only in 36% of suicides. Hanging and gunshot wounds were the cause of death in 28% and 24% of suicides, respectively. Multiple stab wounds were found in 10% of homicides and in 0% of suicides, whereas multiple incised wounds were found in 60% of suicides and only 10% of homicides. However, several unusual instances of suicide were found, including suicides with clothing damage or bone or cartilage injury from blade wounds. No characteristics of blade wounds were definitive for homicide or suicide. History and circumstances of the scene are thus crucial in determining the manner of death.

Conclusion: Abdominal wall endometriosis may be caused by iatrogenic inoculation of the endometrium into the surgical wound. It is strongly recommended that, at the conclusion of the surgical procedure, the abdominal wound be cleaned thoroughly, particularly at both corner sites (especially the operator's side. If an abdominal wall endometriosis is encountered after CS but the patient plans to have future pregnancy and the symptoms are mild, excision of the endometrioma may be deferred until the next indicated CS.

The use of etoricoxib to treat an idiopathic stabbing headache: a case report

Directory of Open Access Journals (Sweden)

O'Connor Mortimer B

2007-09-01

Full Text Available Abstract According to the International Headache Society, idiopathic stabbing headache (ISH, an indomethacin-responsive headache syndrome, is a paroxysmal disorder of short duration manifested as head pain occurring as a single stab or a series of stabs involving the area supplied in the distribution of the first division of the trigeminal nerve. Stabs last for approximately a few seconds, occurring and recurring from once to multiple times per day in an irregular frequency, with no underlying attributable disorder. Previously indomethacin was the principle treatment option for ISH, despite therapeutic failure in up to 35% of cases, until reports showed gabapentin, melatonin and selective cyclo-oxygenase-2 (COX-2 inhibitors were also possibly effective. In this report we present the full case report of an 88 year old lady with a history of untreated ISH where etoricoxib, a selective COX-2 inhibitor, was used to effectively treat her ISH.

Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. We will report the clinical and radiological findings of our personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. We will also try to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. In the last seven years we retrospectively reviewed 31 cases of penetrating liver trauma. The patients were 19 men and 12 women, ranging in age 18 to 73 (mean 42), with penetrating liver injuries from firearms (16 patients) and stab (9 cases) wounds; 6 patients had injuries from different causes. Abdominal CT was carried out in emergency with the CT Angiography (CTA) technique in all patients. In the patients with suspected chest and abdomen involvement CT was performed from the mid-chest for accurate assessment of diaphragm and lung bases and to exclude associated pleuropulmonary damage. Penetrating liver wounds were caused by firearms in 70% of cases, by stabbing in 12% and, in the extant 18%, by other causes such as home accidents, road and work traumas, and liver biopsy. In our series, the liver was most frequently involved, especially by firearms wounds; in our 16 cases the most frequent injuries were hemorrhagic tears. We found bullets in the liver in 6 cases. In one case of home accident the patient wounded himself while slicing bread with a long knife, which cut into the anterior abdominal wall and tore the anterior liver capsule, as seen at CTA. Penetrating wounds to liver and abdomen are less frequent than those to the chest. In the past decade the use of CT has changed the diagnostic and therapeutic approach to such injuries completely, decreasing the resort to explorative laparotomy and hepatorrhaphy. Indeed, CT provides a clear picture of the extent and

Colon trauma is frequent and its prevalence is difficult to establish because of the different factors that intervene in its origin. In Mexico, traumatic colon injuries, albeit stab wounds or gunshot wounds, are on the rise. Our objective was to evaluate the most appropriate management for traumatic colon injuries. We conducted a retrospective study of 178 case files of patients with abdominal trauma and colon lesions during a 5-year period from January 2003 to June 2008 from the General Hospital of Balbuena, Mexico City. The study compared the use of primary closure vs. colostomy, analyzing variables such as sex, age, type of wound, severity of lesion and mortality. There were a total of 178 patients; 156 were male (87.6%) and 22 were female (12.4%). The most affected age group was between 21 and 30 years; 74 patients (41.6%) had stab wounds and 104 patients (58.4%) had gunshot wounds. Management consisted mainly of primary closure in 92 cases (51.7%) vs. colostomy in 86 patients (48.3%). However, 64% of gunshot wounds were treated with colostomy. Reported mortality was 9.55% and this was due to different factors such as multiple organ injury. Treatment of traumatic colon injury should be case specific, taking into account the mechanism of the lesion, its severity and associated injuries.

Laparoscopy is increasingly utilised in the trauma setting. However, its safety and reliability in evaluating and managing retroperitoneal injuries are not known. The aim of this study was to analyse our experience with laparoscopic management of retroperitoneal injuries due to penetrating abdominal trauma (PAT) and to investigate its feasibility, safety and accuracy in haemodynamically stable patients. Over a 4-year period, patients approached laparoscopically with retroperitoneal injuries were analysed. Mechanism, location and severity of injuries were recorded. Surgical procedures, conversion rate and reasons for conversion and outcomes were described. Of the 284 patients with PAT, 56 patients had involvement of retroperitoneum. Stab wounds accounted 62.5% of patients. The mean Injury Severity Score was 7.4 (4-20). Among retroperitoneal injuries, the colon (27%) was the most commonly involved hollow viscera followed by duodenum (5%). The kidney (5%) and the pancreas (4%) were the injured solid organs. The conversion rate was 19.6% and was mainly due to active bleeding (73%). Significantly more patients with gunshot wound were converted to laparotomy (38% vs. 9%). Therapeutic laparoscopy was performed in 36% of patients. There were no recorded missed injuries or mortality. Five (9%) patients developed the Clavien-Dindo Grade 3 complications, three were managed with reoperation, one with drainage/debridement and one with endovascular technique. Laparoscopic management of retroperitoneal injuries is safe and feasible in haemodynamically stable patients with PAT. However, a high conversion rate indicates difficulties in managing these injuries. The requirements are the dexterity in laparoscopy and readiness to convert in the event of bleeding.

The Hidden Story of Innovation: Charity Hospital, Angola Prison, and the Challenging of Surgical Dogma.

Science.gov (United States)

Greiffenstein, Patrick; Hastings, Paul R

2017-02-01

The late 1960s was a period of significant upheaval of social, cultural, and scientific norms. The generally accepted notion of mandatory laparotomy for all penetrating abdominal injuries was among those norms being called into question across the country and many advocated expectant management of selected patients presenting with this type of injury. Leaders of the surgical community published opinions on either side of the argument. The house staff at Charity Hospital during this period was among the busiest in the nation in treating these injuries, many of them inmates of the Louisiana State Penitentiary who used self-inflicted stab wounds to the abdomen as a means of temporary respite from the inhumane conditions in the prison. Inspired, in part, by the overabundance of negative laparotomies among this group, F. Carter Nance went on to systematically challenge the standard of care. This effort constitutes one of the major forces for change of the surgical dogma of mandatory laparotomy for all abdominal stab wounds. It is the first major study to show conclusively that delayed laparotomy for perforated viscous was not significantly detrimental and posed less of a risk than unnecessary laparotomy. The circumstances surrounding this initiative constitute a powerful and heretofore unknown chapter in the history of surgical innovation.

Penetrating chest wound of the foetus

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.

Full Text Available In this study we review our experience in using laparoscopy as a diagnostic and therapeutic tool in dealing with penetrating diaphragmatic injuries due to stab wounds and look at the feasibility of using this procedure in other similar institutions.Thirty patients, all of whom were males 20-30 years of age, presented to the surgical emergency unit of our hospital with upper abdominal and lower chest wall stab wounds between 01-05-1998 and 30-11-2006. Diagnosis of the diaphragm injury was either obvious with omentum herniating through the chest wall, or occult with confirmation of the injury at laparoscopy.All patients underwent diagnostic laparoscopy, which resulted in identification and efficient treatment of eight patients with diaphragmatic injury, and thereby laparotomy was avoided. The procedure converted to open surgery in one patient because of a small left-sided colonic tear. Laparoscopy is an efficient tool for the diagnosis and management of diaphragmatic injuries. It should be used routinely instead of exploratory laparotomy in haemodynamically stable patients with penetrating lower chest injuries.

Full Text Available Background: This study was designed to evaluate the postoperative analgesic efficacy of levobupivacaine (L alone and its combination with clonidine (C or dexmedetomidine (D in wound infiltration technique for abdominal surgeries. Materials and Methods: After ethical committee approval, a double-blind randomized controlled study was conducted on 90 patients (power of study 80%, physical status American Society of Anesthesiologists Grade I and II, aged 18–60 years scheduled for abdominal surgeries over 1 year duration. A standard general anesthetic technique was used. Patients were randomly allocated into three groups, by computer-generated random number table. Patients received wound infiltration during wound closure. Group L received 29 ml of 0.25% levobupivacaine plus 1 ml 0.9% normal saline, Group LC received 29 ml of 0.25% levobupivacaine with 1 ml (3 mcg/kg clonidine, and Group LD received 29 ml of 0.25% levobupivacaine with 1 ml (2 mcg/kg dexmedetomidine. Postoperative rescue analgesia was provided with injection tramadol. Statistical analysis for duration of analgesia was determined by one-way analysis of variance and side effects by Chi-square test. Results: The total duration of analgesia in LD group was 23.4 h, when compared to LC group 20.9 h and L group 11.65 h (P = 0.0001 with excellent to good quality of analgesia in adjuvant group (P < 0.001 and incidence of minimal side effects such as sedation, nausea, and vomiting. Conclusion: Clonidine and dexmedetomidine were the effective adjuvants to levobupivacaine for single shot wound infiltration analgesic technique; however, dexmedetomidine was found to be superior to clonidine.

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

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.

Penetrating injuries to the chest present a frequent and challenging problem, but the majority of these injuries can be managed non-\\operatively. The aim of this study was to describe the incidence of penetrating chest trauma and the ultimate techniques used for operative management, as well as the diagnosis, complications, morbidity and mortality. A retrospective 9-year review of patients who underwent an operative procedure following penetrating chest trauma was performed. The mechanism of injury, gender, age, physiological and outcome parameters, including injury severity score (ISS), chest abbreviated injury scale (AIS) score, lung injury scale score, concomitant injuries, time from admission to operating room, transfusion requirement, indications for thoracotomy, intra-operative findings, operative procedures, length of hospital stay (LOS) and rate of mortality were recorded. A total of 1123 patients who were admitted with penetrating thoracic trauma were investigated. Of these, 158 patients (93 stabbings, 65 gunshots) underwent a thoracotomy within 24 h after the penetrating trauma. There were 146 (92.4%) male and 12 (7.6%) female patients, and their mean age was 25.72 9.33 (range, 15–54) years. The mean LOS was 10.65 8.30 (range, 5–65) days. Patients admitted after a gunshot had a significantly longer LOS than those admitted with a stab wound (gunshot, 13.53 9.92 days; stab wound, 8.76 6.42 days, p chest AIS score (p chest requiring a thoracotomy are uncommon, and lung-sparing techniques have become the most frequently used procedures for lung injuries. The presence of associated abdominal injuries increased the mortality five-fold. Factors that affected mortality were ISS, chest AIS score, SBP, ongoing chest output, blood transfusion volume, diaphragmatic injury and associated abdominal injury.

Actinomyces are gram-positive aerobic-growing bacteria that are part of human bacterial flora. Actinomyces infections, which are more prevalent among men than among women (3:1), usually affect patients in their fourth decade and most often involve A. israelli (85%). thoracic, abdominal or pelvic actinomycosis is uncommon. Pulmonary infections result more from aspiration of oral secretions than from direct extension. We report one case of necrotizing pneumonia of a patient with previous stab wound injury in the affected hemi thorax and an unusual aggressive behavior

The surgical site infection (SSI) is a common complication of abdominal operation. It relates to increased hospital stay, increased healthcare cost, and decreased patient's quality of life. Obesity, usually defined by BMI, is known as one of the risks of SSI. However, the thickness of subcutaneous layers of abdominal wall might be an important local factor affecting the rate of SSI after the abdominal operations. The objective of this study is to assess the importance of the abdominal wall thickness on incisional SSI rate. The subjects of the present study were patients who had undergone major abdominal operations at Thammasat University Hospital between June 2013 and May 2014, and had been investigated with CT scans before their operations. The demographic data and clinical information of these patients were recorded. The thickness ofsubcutaneous fatty tissue from skin down to the most superficial layer of abdominal wall muscle at the surgical site was measured on CT images. The wound infectious complication was reviewed and categorized as superficial and deep incisional SSIfollowing the definition from Centersfor Disease Control and Prevention (CDC) guidelines. The significance ofeach potentialfactors on SSI rates was determined separately with student t-test for quantitative data and χ2-test for categorical data. Then all factors, which had p operative CTscans. Post-operative SSI was 25.2% (35/139), superficial and deep types in 27 and 8 patients, respectively. The comparison of abdominal wall thickness between patients with and without infection was significantly different (20.0 ± 8.4 mm and 16.0 ± 7.2 mm, respectively). When the thickness at 20 mm was used as the cut-off value, 43 of 139 patients had abdominal wall thickness ≥ 20 mm. The incidence of SSI of the thickness ±20 mm group was 37.2% (16/43) and of the less thickness group was 19.8% (19/96), with p operation. However, only abdominal wall thickness and wound classification were still significant

Herpes simplex virus infection following surgery is an unusual postoperative phenomenon. Many mechanisms have been suggested, with the most likely explanation related to latent virus reactivation due to a proinflammatory response in the setting of local trauma. Here, we present a case of herpes simplex virus reactivation in an immunocompetent female following a conventional right lower extremity stab phlebectomy. Salient clinical and physical examination findings are described, and management strategies for herpes simplex virus reactivation are outlined. This is the first known case report of herpes simplex virus reactivation following lower extremity phlebectomy.

Full Text Available In order to achieve enhanced protective and wear (flexibility, less bulkiness properties of ballistic and stab protecting panels the investigation of chemical surface modification of woven p-aramid fabrics was performed applying different chemical composition shear thickening fluid (STF which improves friction inside fabric structure. For the chemical treatment silicic acid and acrylic dispersion water solutions were used and influence of their different concentrations on panels’ protective properties were investigated. Results of ballistic tests of multilayer protective panel have revealed that shear thickening effect was negligible when shooting at high energy range (E > 440 J. Determination of stab resistance of p-aramid panels has shown that different chemical composition of STFs had different influence on protective properties of the panels. Application of low concentrations of silicic acid determined higher stab resistance values comparing to higher concentrations of acrylic dispersion water solutions. At this stage of research stab tests results as ballistic ones determined that STF application for multilayer p-aramid fabrics protective panels is more efficient at low strike energy levels.

Radiographic evaluation of hepatic trauma

The incidence of significant abdominal trauma continues to rise and accounts currently for approximately 10 percent of the annual 130,000 trauma-related deaths in the United States. Over 60 percent of patients are from 10 to 40 years of age, with a striking predominance of males. Children are mostly victims of blunt trauma, while some large reviews of liver trauma in adults show a prevalence of penetrating injuries. Injury to the liver is second only to the spleen in incidence of intraperitoneal injuries. Morbidity and mortality from hepatic trauma are related to the mechanism and extent of injury. Penetrating injuries generally have a lower mortality, about 5 percent, especially if they are due to stab wounds or low velocity gunshot wounds. Shotgun and high velocity gunshot wounds may cause massive fragmentation of the liver and are associated with proportionately greater mortality. The mortality from blunt trauma is from 15 to 45 percent in many large series. Death from isolated liver injury is uncommon, but is usually due to uncontrolled hemorrhage. Injury to other abdominal organs is associated in many cases, as are injuries to the head, chest, and limbs. The extraabdominal injuries are frequently more apparent clinically, but may mask potentially life-threatening abdominal visceral injuries

Despite the numerous advances in recent years, severe abdominal sepsis (with associated organ failure associated with infection) remains a serious, life-threatening condition with a high mortality rate. OA is a viable alternative to the previously used scheduled repeat laparotomy or continuous peritoneal lavage. The use of Negative Pressure Wound Therapy (NPWT) has been described as a successful method of management of the open abdomen. Adding instillation of saline solution to NPWT in a programmed and controlled manner, could offer the clinician an additional tool for the management of complex septic abdomen. To explore if the concept of active two-way therapy (Negative pressure wound therapy with instillation or NPWT-I) yields superior control of underlying, life-threatening abdominal infections and its effects on survival and morbidity in patients with severe abdominal sepsis when management with an open abdomen is required. A retrospective review of 48 patients with severe abdominal sepsis, who were managed with and open abdomen and NPWT-I was performed. NPWT-I was initiated utilizing the same parameters on all patients, this consisted of cycles of instillation of saline solution, which was removed through negative pressure after a short dwell period. We observed the effects on primary fascia closure rate, mortality, hospital and SICU length of stay and associated complications. Our patient group consisted of 20 (42%) males and 28 (58%) females. Average age was 48 years. Mortality in these patients was attributed to pulmonary embolism (n=1), acute renal failure (n=2) and cardiopulmonary arrest (n=1). Average total hospital stay was 24days, and stay in the SICU (n=26) averaged 7.5days. No acute complications related to the NPWT-I. All patients presenting with abdominal compartment syndrome resolved after initiation of the NPWT-I. A total of 46 patients (96%) patients achieved fascia closure after NPWT-I therapy after an average of 6days. Four patients (8%) died

Since its discovery and initial description in the 1960s, the penetrating lesion to the left ninth rib of the Shanidar 3 Neandertal has been a focus for discussion about interpersonal violence and weapon technology in the Middle Paleolithic. Recent experimental studies using lithic points on animal targets suggest that aspects of weapon system dynamics can be inferred from the form of the bony lesions they produce. Thus, to better understand the circumstances surrounding the traumatic injury suffered by Shanidar 3, we conducted controlled stabbing experiments with replicas of Mousterian and Levallois points directed against the thoraces of pig carcasses. Stabs were conducted under both high and low kinetic energy conditions, in an effort to replicate the usual impact forces associated with thrusting spear vs. long-range projectile weapon systems, respectively. Analysis of the lesions produced in the pig ribs, along with examination of goat ribs subjected primarily to high kinetic energy stabs from an independent experiment, revealed consistent differences in damage patterns between the two conditions. In the case of Shanidar 3, the lack of major involvement of more than one rib, the lack of fracturing of the affected and adjacent ribs, and the lack of bony defects associated with the lesion (such as wastage, hinging, and radiating fracture lines) suggests that the weapon that wounded him was carrying relatively low kinetic energy. While accidental injury or attack with a thrusting spear or knife cannot absolutely be ruled out, the position, angulation, and morphology of the lesion is most consistent with injury by a low-mass, low-kinetic energy projectile weapon. Given the potential temporal overlap of Shanidar 3 with early modern humans in western Asia, and the possibility that the latter were armed with projectile weapon systems, this case carries more than simple paleoforensic interest.

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

Edivaldo Massazo Utiyama

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

Lower abdominal wall reconstructions with pedicled rectus femoris flaps

Arashiro, Ken; Nishizeki, Osamu; Ishida, Kunihiro

2003-01-01

During the past 10 years, seven pedicled rectus femoris muscle or musculocutaneous flaps were used to repair lower abdominal defects; three recalcitrant incisional hernias with previous radiotherapy, two long-standing wound infections after synthetic mesh reconstruction, one posttraumatic wall defect and one metastatic tumor. There were two flap complications, one skin paddle necrosis and one wound infection. There was no significant disability of the donor limb encountered. During the two-year and seven month average follow-up, there was no recurrence of the problems except for one minor fascial dehiscence in the patient with metastatic abdominal wall tumor. Easy approach, rapid harvest, relatively large and reliable overlying fascia lata, a single dominant neurovascular pedicle, easy primary closure of the donor site, and minimal donor site morbidity all make the rectus femoris flap a good alternative flap for lower abdominal wall reconstruction. It is especially useful in a condition where synthetic mesh would be unsuitable for defects with infection or recurrent incisional hernia after radiotherapy. (author)

Surgical site infections (SSIs) are frequent complications in colorectal surgery and may lead to burst abdomen, incisional hernia, and increased perioperative costs. Plastic wound ring drapes (RD) were introduced some decades ago to protect the abdominal wound from bacteria and reduce SSIs. There have been no controlled trials examining the benefit of RD in laparoscopic colorectal surgery. The Reduction of wound infections in laparoscopic assisted colorectal resections by plastic wound ring drapes (REDWIL) trial was thus designed to assess their effectiveness in preventing SSIs after elective laparoscopic colorectal resections. REDWIL is a randomized controlled monocenter trial with two parallel groups (experimental group with RD and control group without RD). Patients undergoing elective laparoscopic colorectal resection were included. The primary endpoint was SSIs. Secondary outcomes were colonization of the abdominal wall with bacteria, reoperations/readmissions, early/late postoperative complications, and cost of hospital stay. The duration of follow-up was 6 months. Between January 2008 and October 2010, 109 patients were randomly assigned to the experimental or control group (with or without RD). Forty-six patients in the RD group and 47 patients in the control group completed follow-up. SSIs developed in ten patients with RD (21.7 %) and six patients without RD (12.8 %) (p = 0.28). An intraoperative swab taken from the abdominal wall was positive in 66.7 % of patients with RD and 57.5 % without RD (p = 0.46). The number of species cultured within one swab was significantly higher in those without RD (p = 0.03). The median total inpatient costs including emergency readmissions were 3,402 ± 4,038 in the RD group and 3,563 ± 1,735 in the control group (p = 0.869). RD do not reduce the rate of SSIs in laparoscopic colorectal surgery. The inpatient costs are similar with and without RD.

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.

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

Preoperative povidone-iodine vaginal gel in abdominal hysterectomy: a randomized clinical trial

2007-09-01

Full Text Available Background: Infectious complications of hysterectomy remain common despite the use of antibiotic. The usual existing methods of preoperative antisepsis do not control the vaginal bacteria that are the primary cause of contamination at the surgical site. Our goal was to assess whether febrile morbidity after total abdominal hysterectomy is decreased by the addition of povidone-iodine gel at the vaginal apex after the routine vaginal preparation with povidone-iodine solution.Methods: We carried out a prospective randomized trial on women admitted for elective abdominal hysterectomy. Inclusion criteria included planned abdominal hysterectomy for benign or malignant gynecologic conditions. Exclusion criteria consisted of emergency surgery, current treatment for pelvic infection, and known povidone-iodine allergy. A total of 168 patients were randomized to either the control group or the intervention group, who received 20 cc povidone-iodine gel placed at the vaginal apex immediately before the operation. Both groups received the routine preoperative preparation of antimicrobial prophylaxis, abdominal and vaginal scrubbing with povidone-iodine solution prior to the operation. The primary outcome was post-operative febrile morbidity. Other outcomes included abdominal wound infection, vaginal cuff cellulitis or pelvic abscess. Data was analyzed using Fisher's exact test. p<0.05 was considered statistically significant.Results: The overall rate of febrile morbidity was 20.5%. Febrile morbidity occurred in ten of 80 (12.5% women receiving the povidone-iodine gel preparation and 24 of 86 (27.9% women not receiving the gel (p<0.05. The rate of abdominal wound infection was 18.6% (16 in the control group, and 5% (4 in the gel group (p<0.05. Vaginal cuff cellulitis was seen in three patients from the control group versus one woman from the gel group (p>0.05. Pelvic abscess was diagnosed in one patient from the control group and in no patients from the

1987-05-01

We have led over a four year period, from 1981 to 1985, a prospective study on all cases of penetrating chest wounds (77 cases) in the intensive Care unit and the Department of Thoracic Surgery at the Avicenne Hospital. These wounds, involving young males, are fortunately mostly benign. Their seriousness is based on the abdominal or mediastinal hemorrhage as well as lesions to the vital organs which need an emergency intervention. The latter, nevertheless, with the help of the mobile reanimation service for transfering the patient, has diminished the mortality rate to 2.6 per cent. Following their experiment and after a review of the literature, the authors expose their method of management of the penetrating chest wounds.

This audit examines our total experience with penetrating thoracic trauma. It reviews all the patients who were brought alive to our surgical service and all who were taken directly to the mortuary. The group of patients who underwent emergency operation for penetrating thoracic trauma is examined in detail. A prospective trauma registry is maintained by the Pietermaritzburg Metropolitan Complex. This database was retrospectively interrogated for all patients requiring an emergency thoracic operation for penetrating injury from July 2006 till July 2009. A retrospective review of mortuary data for the same period was undertaken to identify patients with penetrating thoracic trauma who had been taken to the forensic mortuary. Over the 3-year period July 2006 to July 2009, a total of 1186 patients, 77 of whom were female, were admitted to the surgical services in Pietermaritzburg with penetrating thoracic trauma. There were 124 gunshot wounds and 1062 stab wounds. A total of 108 (9%) patients required emergency operation during the period under review. The mechanism of trauma in the operative group was stab wounds (n = 102), gunshot wound (n = 4), stab with compass (n = 1), and impalement by falling on an arrow (n = 1). Over the same period 676 persons with penetrating thoracic trauma were taken to the mortuary. There were 135 (20%) gunshot wounds of the chest in the mortuary cohort. The overall mortality for penetrating thoracic trauma was 541 (33%) of 1603 for stab wounds and 135 (52%) of 259 for gunshot wounds of the chest. Among the 541 subjects with stab wounds from the mortuary cohort, there were 206 (38%) with cardiac injuries. In the emergency operation group there were 11 (10%) deaths. In 76 patients a cardiac injury was identified. The other injuries identified were lung parenchyma bleeding (n = 12) intercostal vessels (n = 10), great vessels of the chest (n = 6), internal thoracic vessel (n = 2), and pericardial injury with no myocardial injury (n = 2

Laparoscopic Bullet Removal in a Penetrating Abdominal Gunshot

2016-01-01

Full Text Available Penetrating abdominal trauma has been traditionally treated by exploratory laparotomy. Nowadays laparoscopy has become an accepted practice in hemodynamically stable patient without signs of peritonitis. We report a case of a lower anterior abdominal gunshot patient treated laparoscopically. A 32-year-old male presented to the Emergency Department with complaint of gunshot penetrating injury at left lower anterior abdominal wall. The patient had no symptoms or obvious bleeding and was vitally stable. On examination we identified 1 cm diameter entry wound at the left lower abdominal wall. The imaging studies showed the bullet in the peritoneal cavity but no injured intraperitoneal and retroperitoneal viscera. We decided to remove the bullet laparoscopically. Twenty-four hours after the intervention the patient was discharged. The decision for managing gunshot patients should be based on clinical and diagnostic findings. Anterior abdominal injuries in a stable patient without other health problems can be managed laparoscopically.

The authors report the first known case of a penetrating spinal injury from a swordfish, in which the patient presented with a small stab wound and hemiparesis. The presentation of a fisherman with hemiparesis and a harmless-looking stab wound must alert clinicians to the possibility of penetrating swordfish injuries to the spine.

Full Text Available Abstract Introduction Most trauma patients are drunk at the time of injury. Up to 2% of traumatized patients develop sepsis, which considerably increases their mortality. Inadequate wound healing of the colonic repair can lead to postoperative complications such as leakage and sepsis. Objective To assess the effects of acute alcohol intoxication on colonic anastomosis wound healing in septic rats. Methods Thirty six Wistar rats were allocated into two groups: S (induction of sepsis and AS (alcohol intake before sepsis induction. A colonic anastomosis was performed in all groups. After 1, 3 or 7 days the animals were killed. Weight variations, mortality rate, histopathology and tensile breaking strength of the colonic anastomosis were evaluated. Results There was an overall mortality of 4 animals (11.1%, three in the group AS (16.6% and one in the S group (5.5%. Weight loss occurred in all groups. The colon anastomosis of the AS group didn’t gain strength from the first to the seventh postoperative day. On the histopathological analysis there were no differences in the deposition of collagen or fibroblasts between the groups AS and S. Conclusion Alcohol intake increased the mortality rate three times in septic animals. Acute alcohol intoxication delays the acquisition of tensile strength of colonic anastomosis in septic rats. Therefore, acute alcohol intoxication before sepsis leads to worse prognosis in animal models of the abdominal trauma patients.

Fuentes-Ramírez, Alejandra

2017-06-01

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.

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

Diaphragmatic injuries include wounds and diaphragm ruptures, due to a thoracoabdominal blunt or penetrating traumas. Their incidence ranges between 0.8 and 15 %. The diagnosis is often delayed, despite several medical imaging techniques. The surgical management remains controversal, particularly for the choice of the surgical approach and technique. The mortality is mainly related to associated injuries. The aim of our study was to evaluate the incidence of diaphragmatic injuries occuring in thoraco-abdominal traumas, and to discuss their epidemiology, diagnosis and treatment. We performed a retrospective study over a period of 21 years, between January 1994 and June 2015 at the Department of General Surgery of the Aristide Le Dantec hospital in Dakar, Senegal. All patients diagnosed with diaphragmatic injuries were included in the study. Over the study period, 1535 patients had a thoraco-abdominal trauma. There were 859 cases of blunt trauma, and 676 penetrating chest or abdominal trauma. Our study involved 20 cases of diaphragmatic injuries (1.3 %). The sex-ratio was 4. The mean age was 33 years. Brawls represented 83.3 % (17 cases). Stab attacks represented 60 % (12 cases). The incidence of diaphragmatic injury was 2.6 %. The wound was in the thorax in 60 % (seven cases). Chest radiography was contributory in 45 % (nine cases). The diagnosis of wounds or ruptures of the diaphragm was done preoperatively in 45 % (nine cases). The diaphragmatic wound was on the left side in 90 % (18 cases) and its mean size was 4.3 cm. The surgical procedure involved a reduction of herniated viscera and a suture of the diaphragm by "X" non absorbable points in 85 % (17 cases). A thoracic aspiration was performed in all patients. Morbidity rate was 10 % and mortality rate 5 %. The diagnosis of diaphragmatic rupture and wounds remains difficult and often delayed. They should be kept in mind in any blunt or penetrating thoraco-abdominal trauma. Diaphragmatic lesions

Total colectomy with ileorectal anastomosis (IRA) is the most widely adopted procedure. The aim of this study was to introduce a minimally invasive procedure, i.e., minilaparotomy with laparoscopic-assisted procedure, by abdominal wall lifting for IRA in patients with slow transit constipation (STC). Six STC patients (6 women, aged 40-69 years, mean age 56.3 years) underwent minilaparotomy with gasless laparoscopic-assisted approach by abdominal wall lifting for IRA. The present procedure involved a 7-cm lower abdominal median incision made at the beginning of the operation. 12 mm ports were also placed in the right and left upper abdominal quadrant positions. The upper abdominal wall was lifted by a subcutaneous Kirshner wire. The small wound was pulled upward and/or laterally by retractors (abdominal lifting) and conventional surgical instruments were used through the wound. Occasionally laparoscopic assistance was employed. The terminal ileum with total colon was brought out through the small wound and transected, approximately 5 cm from the ileocecal valve. The colon was also resected at the level of promontrium. Then, IRA was performed in the instruments. The total surgical time was 197.7 +/- 33.9 min and the mean estimated blood loss was 176.8 +/- 42.2 ml. There was no surgical mortality. Post-operative hospitalization was 8.1 +/- 2.1 days. Six months after surgery, they defecated 1.8 +/- 2.1 times daily, have no abdominal distension, pain, and incontinence. The patients also take no laxatives. All subjects were satisfied with this procedure. Minilaparotomy with gasless laparoscopic-assisted IRA by abdominal wall lifting could be a safe and efficient technique in the treatment of STC.

Full Text Available Abdominal pocketing is one of the most useful methods in salvation of compromised replanted fingertips. Abdominal pocketing has generally been performed in the ipsilateral lower abdominal quadrant, but we have also performed contralateral pocketing at our institute. To determine which approach is more beneficial, a total of 40 patients underwent an abdominal pocketing procedure in either the ipsilateral or contralateral lower abdominal quadrant after fingertip replantation. Dates of abdominal pocketing after initial replantation, detachment after abdominal pocketing, range of motion (ROM before abdominal pocketing, and sequential ROM after the detachment operation and date of full ROM recovery and Disabilities of Arm, Shoulder, and Hand questionnaire (DASH score were recorded through medical chart review. Mean detachment date, mean abduction of shoulder after the detachment operation, and mean days to return to full ROM were not significantly different between the ipsilateral and contralateral pocketing groups. However, the mean DASH score was significantly lower in the contralateral group than the ipsilateral group. There were also fewer postoperative wound complications in the contralateral group than in the ipsilateral group. We, therefore, recommend contralateral abdominal pocketing rather than ipsilateral abdominal pocketing to increase patient comfort and reduce pain and complications.

To determine history, signalment, physical examination findings, treatment, complications, outcome, and prognostic indicators of dogs and cats treated for gunshot wounds at an urban veterinary referral hospital. Retrospective study. 82 dogs and 2 cats. Young (exploratory laparotomy. Animals with thoracic injuries usually could be managed with conservative treatment or thoracocentesis. Only 1 animal underwent thoracotomy. Wound infection developed in 4 animals. Initial treatment of animals with gunshot wounds should include administration of antibiotics effective against gram-positive and -negative bacteria. Most dogs with gunshot wounds that receive adequate treatment can be expected to survive. However, dogs with vertebral column or abdominal wounds may have a worse prognosis than dogs with thoracic or limb injuries.

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.

Full Text Available BACKGROUND Blunt abdominal trauma is an emergency and is associated with significant morbidity and mortality. The aim of the study is to study incidence, demographic profile, epidemiological factors, mechanism of trauma, treatment modalities, associated injuries, postoperative complications and morbidity and mortality. MATERIALS AND METHODS A retrospective analysis of 72 patients of blunt abdominal trauma who were admitted in government general hospital between May 2013 to April 2015 in Department of General Surgery, Government General Hospital, Guntur, with in a span of 24 months were studied. Demographic data, mechanism of trauma, management and outcome were studied. RESULTS Most of the patients in our study were in the age group of 21-30 years. Spleen was the commonest organ involved and most common procedure performed was splenectomy. Most common extra-abdominal injury was rib fractures. Wound infection was the commonest complication. CONCLUSION Initial resuscitative measures, thorough clinical examination and correct diagnosis forms the vital part of the management. FAST is more useful in blunt abdominal trauma patients who are unstable. X-ray revealed 100% accuracy in hollow viscous perforation in blunt abdominal trauma patients. CT abdomen is more useful in stable patients. Definitive indication for laparotomy was haemodynamic instability and peritonitis. Associated injuries influenced morbidity and mortality. Early diagnosis and prompt treatment can save many lives.

An open abdomen complicated with small-bowel fistulae becomes a complex wound for local infection, systemic sepsis and persistent soiling irritation by intestinal content. While controlling the fistulae drainage, protecting surrounding skin, healing the wound maybe a challenge. In this paper we described a 68-year-old female was admitted to emergency surgery in general surgery department with severe abdomen pain. Resection part of the injured small bowel, drainage of the intra-abdominal abscess, and fashioning of a colostomy were performed. She failed to improve and ultimately there was tenderness and lot of pus under the skin around the fistulae. The wound started as a 3-cm lesion and progressed to a 6 ×13  (78 cm) around the stoma. In our case we present a novel device for managing colostomy wound combination with negative pressure wound therapy. This tube allows for an effective drainage of small-bowel secretion and a safe build-up of granulation tissue. Also it could be a barrier between the bowel suction point and foam. Management of open abdomen wound involves initial dressing changes, antibiotic use and cutaneous closure. When compared with traditional dressing changes, the NPWT offers several advantages including increased granulation tissue formation, reduction in bacterial colonization, decreased of bowel edema and wound size, and enhanced neovascularization.

To describe the clinical features, diagnostic findings, treatment, and outcome of a dog with acute abdominal pain and hemoperitoneum secondary to a presumptive intraperitoneal (IP) snakebite. A 10-month-old castrated male mixed-breed dog was evaluated for suspected snake envenomation. The dog presented recumbent and tachycardic with signs of severe abdominal pain. Two cutaneous puncture wounds and hemoperitoneum were discovered during evaluation. Ultrasonographic examination revealed communication of the wounds with the peritoneal cavity. The dog was treated with supportive care, parenteral analgesia, packed red blood cell and fresh frozen plasma transfusions, crotalid antivenom, and placement of an IP catheter to provide local analgesia. The dog recovered fully and was discharged 5 days after initial presentation. To our knowledge, this is the first report of IP envenomation accompanied by hemorrhage treated with continuous IP analgesia in the veterinary literature. © Veterinary Emergency and Critical Care Society 2015.

The authors' earlier retrospective report of surgical complications after abdominal contouring surgery provided evidence that post-bariatric surgery patients are at increased risk of developing wound complications compared with a normal population. This prospective pilot study was designed as a comparative analysis of both surgical and wound healing characteristics between massive weight loss and normal patients who present for abdominal contouring surgery. Excisional wounds were created and polytetrafluoroethylene tubing was inserted during the preoperative period for later harvesting in patients undergoing abdominal contouring following Roux-en-Y gastric bypass for weight loss (n = 16) or abdominoplasty (n = 17). Wound fluids were sequentially collected from drains and subjected to matrix metalloproteinase (MMP) analysis. Standard postsurgical complications were documented. Surgical complications were more common in weight loss patients (47 percent) than in control patients (25 percent). MMP analyses showed that MMP-9 levels remained significantly elevated at postoperative day 4 in patients who subsequently experienced complications in either the weight loss group (p = 0.02) or the control group (p = 0.03). Other parameters showed no significant differences between massive weight loss patients and controls. Although many markers were examined, the ratio of MMP-9 to albumin was the only predictor of postsurgical complications in any group. This lends further support to growing evidence that MMP-9 may be a useful biomarker of postsurgical complications. This pilot work showed no causal factors that explain the higher rates of postsurgical complications in the post-bariatric surgery patient population. Risk, II.

Negative pressure wound therapy (NPWT) has been widely adopted to treat laparostomy, abdominal compartment syndrome (ACS) and complicated wounds associated with tissue loss. The method presents specific aspects, advantages and indications in Pediatrics. Our aim is to review the evidence available about NPWT in children. Active search for papers about NPWT in Pediatric patients. Papers referring to orthopedic problems, wound complications after Cardiac Surgery or burns were excluded. The method shows good results to treat ACS, complicated wounds and abdominal wall malformations in neonates, including prematures. Periwound skin protection, monitoring of fluid losses and fine tuning of negative pressure levels according to age are necessary. Less pain, quicker recovery, less frequent dressing changes, possible recovery of exposed surgical hardware, granulation and shrinkage of the wound are advantages of the method over other kinds of dressing. NPWT is contraindicated over blood vessels and exposed nerves. Debridement is needed before usage over necrotic areas. Enteric fistulae are not contraindications. Complications are rare, mainly foam retention and dermatitis/skin maceration. The possibility of fistulae being caused by NPWT remains debatable. NPWT is widely used in Pediatrics, including neonates and premature, but the evidence available about the method is scarce and low quality. Complications are uncommon and mostly manageable. A possible causal relationship between NPWY and enteric fistula remains unclear. Adult devices and parameters have been adapted to children's use. Extra care is needed to protect the delicate tissues of Pediatric patients. Comparative research to define differential costs, indications and advantages of the method, specific indications and limits of NWTP in Pediatrics is needed. Review. IV.

Penetrating spinal cord injuries (SCIs) are an uncommon injury and not reported very frequently. SCIs cause sensory, motor and genitourinary system problems or a combination of sensorimotor dysfunctions. These are among the most debilitating kinds of disorders and negatively affect quality of life, not only for the patient, but also for their family members. Therefore, the present study aims to evaluate complete or incomplete SCIs and the course of the injury and the prognosis for SCIs caused by stab wounds. This case-series design study was performed on 57 patients attending the emergency department of Taleqani Trauma Center (Kermanshah, Iran) due to SCIs caused by violent encounters involving sharp objects such as a knife, dagger, whittle and Bowie-knife between 1999 and 2011. An assessment of sensory and motor functions was performed as part of the neurological examination on admission, and during the treatment, using the Frankel Classification grading system, and the results were recorded. The average age of patients was 27 years (SD= 7.9, Range=17 to 46 years). The results of the study showed a proportion of cervical, thoracic and lumbar injuries of 23 (40%), 24 (42%) and 10 (18%), respectively. There was no case of cerebrospinal fluid leakage (CSF) or infection at the wound site in the subjects. Regarding the extent of the SCI, the combined neurological assessment showed that several patients (43%) had a complete SCI with no sensory and motor functions in the sacral segments and the segments below the site of injury. In 32 patients (57%) incomplete injuries were observed; i.e. they showed only some degrees of sensory-motor functions that were below the neurological level. Both complete and incomplete SCIs are of great importance because the prognosis of SCI is directly associated with the location and extent of injury. It should be considered that partial recovery from SCIs is possible in few cases of complete injuries. Therefore, all the patients should be

Stab injury and device implantation within the brain results in inversely multiphasic neuroinflammatory and neurodegenerative responses

An estimated 25 million people in the US alone rely on implanted medical devices, ˜2.5 million implanted within the nervous system. Even though many devices perform adequately for years, the host response to medical devices often severely limits tissue integration and long-term performance. This host response is believed to be particularly limiting in the case of intracortical microelectrodes, where it has been shown that glial cell encapsulation and localized neuronal cell loss accompany intracortical microelectrode implantation. Since neuronal ensembles must be within ˜50 µm of the electrode to obtain neuronal spikes and local field potentials, developing a better understanding of the molecular and cellular environment at the device-tissue interface has been the subject of significant research. Unfortunately, immunohistochemical studies of scar maturation in correlation to device function have been inconclusive. Therefore, here we present a detailed quantitative study of the cellular events and the stability of the blood-brain barrier (BBB) following intracortical microelectrode implantation and cortical stab injury in a chronic survival model. We found two distinctly inverse multiphasic profiles for neuronal survival in device-implanted tissue compared to stab-injured animals. For chronically implanted animals, we observed a biphasic paradigm between blood-derived/trauma-induced and CNS-derived inflammatory markers driving neurodegeneration at the interface. In contrast, stab injured animals demonstrated a CNS-mediated neurodegenerative environment. Collectively these data provide valuable insight to the possibility of multiple roles of chronic neuroinflammatory events on BBB disruption and localized neurodegeneration, while also suggesting the importance to consider multiphasic neuroinflammatory kinetics in the design of therapeutic strategies for stabilizing neural interfaces.

Previous abdominal wall surgery is viewed as a contraindication to abdominal free tissue transfer. We present two patients who underwent multiple abdominal liposuction procedures, followed by successful free deep inferior epigastric artery perforator flap. We review the literature pertaining to reliability of abdominal free flaps in those with previous abdominal surgery. Review of case notes and radiological investigations of two patients, and a PubMed search using the terms "DIEP", "deep inferior epigastric", "TRAM", "transverse rectus abdominis", "perforator" and "laparotomy", "abdominal wall", "liposuction", "liposculpture", "fat graft", "pfannenstiel", with subsequent appraisal of relevant papers by the first and second authors. Patient 1 had 3 episodes of liposuction from the abdomen for fat grafting to a reconstructed breast. Subsequent revision reconstruction of the same breast with DIEP flap was preceded by CT angiography, which demonstrated normal perforator anatomy. The reconstruction healed well with no ischaemic complications. Patient 2 had 5 liposuction procedures from the abdomen to graft fat to a wide local excision defect. Recurrence of cancer led to mastectomy and immediate reconstruction with free DIEP flap. Preoperative MR angiography demonstrated a large perforator right of the umbilicus, with which the intraoperative findings were consistent. The patient had an uneventful recovery and good healing with no fat necrosis or wound dehiscence. We demonstrate that DIEP flaps can safely be raised without perfusion-related complications following multiple liposuction procedures to the abdomen. The safe interval between procedures is difficult to quantify, but we demonstrate successful free flap after 16 months.

In the field of protective gear, developers always aim for lighter and more flexible material in order to increase the wearing comfort. Suppliers now work on knitted garments in the sports-sector as well as in workwear and protective gear for policemen or security-agents. In a recent project different knitted structures made of a poly(p-phenylene-2,6-benzobisoxazole) (PBO)-multifilament were compared to their counterparts made of para-aramid. In focus of the comparison stood the stab-resistance linked to either the mass per unit area or the stitch density. The tested fabrics were produced on hand flat knitting machines as well as on electronical flat knitting machines of the type Stoll CMS 330TC4, in order to analyse fabrics with different tightness factor and machine gauges. The stab resistance of the different knitted fabrics was examined according to the standard of the Association of Test Laboratories for Bullet, Stab or Pike Resistant Materials and Construction Standards. The presentation includes the depiction of the results of the test series and their interpretation. Furthermore it will give an outlook on most suitable combinations of materials and structures to be used in protective gear.

The management of complex pancreatic injuries.

Krige, J E J; Beningfield, S J; Nicol, A J; Navsaria, P

2005-08-01

Major injuries of the pancreas are uncommon, but may result in considerable morbidity and mortality because of the magnitude of associated vascular and duodenal injuries or underestimation of the extent of the pancreatic injury. Prognosis is influenced by the cause and complexity of the pancreatic injury, the amount of blood lost, duration of shock, speed of resuscitation and quality and nature of surgical intervention. Early mortality usually results from uncontrolled or massive bleeding due to associated vascular and adjacent organ injuries. Late mortality is a consequence of infection or multiple organ failure. Neglect of major pancreatic duct injury may lead to life-threatening complications including pseudocysts, fistulas, pancreatitis, sepsis and secondary haemorrhage. Careful operative assessment to determine the extent of gland damage and the likelihood of duct injury is usually sufficient to allow planning of further management. This strategy provides a simple approach to the management of pancreatic injuries regardless of the cause. Four situations are defined by the extent and site of injury: (i) minor lacerations, stabs or gunshot wounds of the superior or inferior border of the body or tail of the pancreas (i.e. remote from the main pancreatic duct), without visible duct involvement, are best managed by external drainage; (ii) major lacerations or gunshot or stab wounds in the body or tail with visible duct involvement or transection of more than half the width of the pancreas are treated by distal pancreatectomy; (iii) stab wounds, gunshot wounds and contusions of the head of the pancreas without devitalisation of pancreatic tissue are managed by external drainage, provided that any associated duodenal injury is amenable to simple repair; and (iv) non-reconstructable injuries with disruption of the ampullary-biliary-pancreatic union or major devitalising injuries of the pancreatic head and duodenum in stable patients are best treated by

Most abdominal wall incisional hernias can be repaired by primary closure. However, where the defect is large or there is tension on the closure, the use of a prosthetic material is indicated. Expanded polytetrafluoroethylene (PTFE) patches were used to repair incisional hernias in 28 patients between November 1983 and December 1986. Twelve of these patients (43%) had a prior failure of a primary repair. Reherniation occurred in three patients (10.7%). Wound infections developed in two patients (7.1%), both of whom had existing intestinal stomas, one with an intercurrent pelvic abscess. The prosthetic patch was removed in the patient with the abscess, but the infection was resolved in the other without sequelae. Septic complications did not occur after any operations performed in uncontaminated fields. None of the patients exhibited any undue discomfort, wound pain, erythema, or induration. Complications related to adhesions, erosion of the patch material into the viscera, bowel obstruction, or fistula formation did not occur. Based on this clinical experience, the authors believe that the PTFE patch appears to represent an advance in synthetic abdominal wall substitutes. Images Fig. 1. Fig. 2(left)., Fig. 3(right).

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.

The selective conservative management of small pneumothoraces (PTXs) following stab injuries is controversial. We reviewed a cohort of patients managed conservatively in a high volume trauma service in South Africa. A retrospective review over a 2-year period identified 125 asymptomatic patients with small PTXs measuring chest radiograph who were managed conservatively. Of the 125 patients included in the study, 92% were male (115/125), and the median age for all patients was 21 years (19-24). Ninety-seven per cent (121/125) of the weapons involved were knives, and 3% (4/125) were screwdrivers. Sixty-one per cent of all injuries were on the left side. Eighty-two per cent (102/125) sustained a single stab, and 18% (23/125) had multiple stabs. Thirty-nine per cent (49/125) had a PTX <0.5 cm (Group A), 26% (32/125) were ≥ 0.5 to <1 cm (Group B), 19% (24/125) were ≥ 1 to <1.5 cm (Group C) and 15% (20/125) were ≥ 1.5 to <2 cm (Group D). Three per cent of all patients (4/125) eventually required ICDs (one in Group C, three in Group D). All four patients had ICDs in situ for 24 h. The remaining 97% (121/125) were all managed successfully by active clinical observation alone. There were no subsequent readmissions, morbidity or mortality as a direct result of our conservative approach. The selective conservative management of asymptomatic small PTXs from stab injuries is safe if undertaken in the appropriate setting.

Prophylactic antibiotics for penetrating abdominal trauma.

Penetrating abdominal trauma occurs when the peritoneal cavity is breached. Routine laparotomy for penetrating abdominal injuries began in the 1800s, with antibiotics first being used in World War II to combat septic complications associated with these injuries. This practice was marked with a reduction in sepsis-related mortality and morbidity. Whether prophylactic antibiotics are required in the prevention of infective complications following penetrating abdominal trauma is controversial, however, as no randomised placebo controlled trials have been published to date. There has also been debate about the timing of antibiotic prophylaxis. In 1972 Fullen noted a 7% to 11% post-surgical infection rate with pre-operative antibiotics, a 33% to 57% infection rate with intra-operative antibiotic administration and 30% to 70% infection rate with only post-operative antibiotic administration. Current guidelines state there is sufficient class I evidence to support the use of a single pre-operative broad spectrum antibiotic dose, with aerobic and anaerobic cover, and continuation (up to 24 hours) only in the event of a hollow viscus perforation found at exploratory laparotomy. To assess the benefits and harms of prophylactic antibiotics administered for penetrating abdominal injuries for the reduction of the incidence of septic complications, such as septicaemia, intra-abdominal abscesses and wound infections. Searches were not restricted by date, language or publication status. We searched the following electronic databases: the Cochrane Injuries Group Specialised Register, CENTRAL (The Cochrane Library 2013, issue 12 of 12), MEDLINE (OvidSP), Embase (OvidSP), ISI Web of Science: Science Citation Index Expanded (SCI-EXPANDED), ISI Web of Science: Conference Proceedings Citation Index- Science (CPCI-S) and PubMed.

Full Text Available BACKGROUND In the recent times there has been increased incidence of abdominal trauma cases due to several causes. Quick and prompt intervention is needed to decrease the mortality of the patients. So we conducted a study to assess the cause and the management of abdominal trauma cases in our institution. The aim of this study was to know the incidence of blunt and penetrating injuries and their causes, age and sex incidence, importance of various investigations, mode of treatment offered and post-operative complications. To study the cause of death and evolve better management. MATERIALS AND METHODS The present study comprises of patients admitted to and operated in various surgical units in the Department of Surgery at Government General Hospital, attached to Guntur Medical College Guntur, from August 2014 to October 2016. RESULTS Increase incidence seen in age group 20-29 years (30%. Male predominance 77.5%. Mechanism of injury–road traffic accidents 65%. Isolated organ injury–colon and rectum 40%. Other associated injuries–chest injuries with rib fractures 7.5%. Complications–wound infection 17.5%. Duration of hospital stay 8–14 days. Bowel injury management–closure of perforation 84.6%. Resection anastomosis 15.38%. CONCLUSION Thorough clinical examination, diagnostic paracentesis, plain X-ray erect abdomen and ultrasound proved to be very helpful in the diagnosis of intra-abdominal injuries. Spleen is the commonest organ involved in blunt trauma and colon is the commonly injured organ in penetrating abdominal trauma, many patients have associated extremity and axial skeleton injuries. With advances in diagnosis and intensive care technologies, most patients of solid visceral injuries with hemodynamic stability can be managed conservatively. Surgical site infection is the most common complication following surgery. The mortality is high; reason might be patient reaching the hospital late, high incidence of postoperative septic

Open injuries to the face involving the external carotid artery are uncommon. These injuries are normally associated with laceration of the facial nerve because this nerve is more superficial than the external carotid artery. Hence, external carotid artery lesions are usually associated with facial nerve dysfunction. We present an unusual case report in which the patient had an injury to this artery with no facial nerve compromise. A 25-year-old Portuguese man sustained a stab wound injury to his right preauricular region with a broken glass. Immediate profuse bleeding ensued. Provisory tamponade of the wound was achieved at the place of aggression by two off-duty doctors. He was initially transferred to a district hospital, where a large arterial bleeding was observed and a temporary compressive dressing was applied. Subsequently, the patient was transferred to a tertiary hospital. At admission in the emergency room, he presented a pulsating lesion in the right preauricular region and slight weakness in the territory of the inferior buccal branch of the facial nerve. The physical examination suggested an arterial lesion superficial to the facial nerve. However, in the operating theater, a section of the posterior and lateral flanks of the external carotid artery inside the parotid gland was identified. No lesion of the facial nerve was observed, and the external carotid artery was repaired. To better understand the anatomical rationale of this uncommon clinical case, we dissected the preauricular region of six cadavers previously injected with colored latex solutions in the vascular system. A small triangular space between the two main branches of division of the facial nerve in which the external carotid artery was not covered by the facial nerve was observed bilaterally in all cases. This clinical case illustrates that, in a preauricular wound, the external carotid artery can be injured without facial nerve damage. However, no similar description was found in

Scarless abdominal fat graft harvest for neurosurgical procedures: technical note.

Trinh, Victoria T; Duckworth, Edward A M

2015-02-01

Background Abdominal fat grafts are often harvested for use in skull base reconstruction and cerebrospinal fluid (CSF) leak repairs, and for operations traversing the nasal sinuses or mastoid bone. Although the endoscopic transnasal surgery has gained significant popularity, in part because it is considered "scarless," a common adjunct, the abdominal fat graft, can result in a disfiguring scar across the abdomen. Objective This is the first report of a scarless abdominal fat graft technique for skull base reconstruction. Methods Ten patients with a median age of 56.5 years (range: 45-73 years) underwent endoscopic transsphenoidal tumor resection with intraumbilical fat graft harvest. Careful circumferential fat dissection at the umbilicus, with progressive retraction of the graft, was crucial to ensure maximal visualization and to prevent injury to the subcutaneous vessels and rectus fascia. Results Following reconstruction of the sellar skull base, all patients did well postoperatively with no evidence of CSF leak. At 12-week follow-up for all patients, there was no evidence of scar, intracavity hematoma, or wound infection. Conclusions Fat graft harvest through an intraumbilical incision results in a scar-free abdominal harvest, and is a useful procedural adjunct to complement "scarless" brain surgery.

Colon injury has been associated with a high risk of septic complications and mortality. We prospectively studied the pattern, management, outcome, and prognostic factors in patients who sustained penetrating colon injuries. Sixty patients who presented to our hospital with penetrating colon injuries over a ten-year period (1992 to 2001) were studied. Colon wounds were caused by gunshots in 55 (91.7 percent) patients and knife stabs in 5 (8.3 percent). There was a delay of more than 12 hours before laparotomy in 30 (50 percent) patients. Moderate or major fecal contamination of the peritoneal cavity occurred in 58 (96.7 percent) patients. The average penetrating abdominal trauma index score was 25.9 and 20 (33.3 percent) patients sustained Flint Grade 3 colon injury. Associated intra-abdominal injuries occurred in the small bowel (73.3 percent), liver (25 percent), stomach (23.3 percent), and mesentery (16.7 percent). Right colon wounds (35) were managed by primary repair in 24 (68.6 percent) patients and proximal diverting colostomy in 11 (31.4 percent), whereas left colon wounds (25) were managed by diverting colostomy in 22 (88.0 percent) patients and primary repair in 3 (12.0 percent) patients. Common complications included wound infection (56.7 percent), septicemia (31.7 percent), and enterocutaneous fistula (16.7 percent). The overall mortality rate was 33.3 percent and colon injury-related mortality was 21.7 percent. Presence of destructive colon injury was associated with a greater than fourfold increased incidence of death. Other significant risk factors included shock on admission, major fecal contamination, duration of operation more than four hours, penetrating abdominal trauma index score >25, and more than two postoperative complications. There was no difference in outcome between patients who had primary repair and those undergoing diverting colostomy. Colostomy closure-related morbidity was 21 percent and mortality was 5.3 percent.

To compare the electrocautery incision with scalpel incision in patients undergoing abdominal surgery using a midline incision with respect to incision time, blood loss during incision, postoperative incision site pain and wound infection. Patients undergoing midline abdominal surgery were randomized into electrocautery and scalpel groups. The incision dimensions, incision time and blood loss during incision were noted intraoperatively. Postoperative pain and wound infection were recorded on every postoperative day for one week. 41 patients in each of the two groups were analyzed. Gender and age distribution was similar in both the groups. The mean incision time per unit wound area in the electrocautery group and scalpel group was 9.40 ± 3.37 s/cm(2) and 9.07 ± 3.40 s/cm(2) (p = 0.87) respectively. The mean blood loss per unit wound area was significantly lower in the electrocautery group at 6.46 ± 3.94 ml when compared to that of 23.40 ± 15.28 ml in the scalpel group (p= electrocautery and scalpel groups (14.63% vs. 12.19%; p = 0.347). With a comparable Postoperative incision site pain, wound infection rate and significantly lower blood loss with the equal time taken for the incision, electrocautery can be considered safe and effective in making skin incision in midline laparotomy compared to scalpel incision.

Recent studies report the safety and feasibility of performing delayed anastomosis (DA) in patients undergoing damage control laparotomy (DCL) for destructive colon injuries (DCIs). Despite accumulating experience in both civilian and military trauma, questions regarding how to best identify high-risk patients and minimize the number of anastomosis-associated complications remain. Our current practice is to perform a definitive closure of the colon during DCL, unless there is persistent acidosis, bowel wall edema, or evidence of intra-abdominal abscess. In this study, we evaluated the safety of this approach by comparing outcomes of patients with DCI who underwent definitive closure of the colon during DCL versus patients managed with colostomy with or without DCL. We performed a retrospective chart review of patients with penetrating DCI during 2003 to 2009. Severity of injury, surgical management, and clinical outcome were assessed. Sixty patients with severe gunshot wounds and three patients with stab wounds were included in the analysis. DCL was required in 30 patients, all with gunshot wounds. Three patients died within the first 48 hours, three underwent colostomy, and 24 were managed with DA. Thirty-three patients were managed with standard laparotomy: 26 patients with primary anastomosis and 7 with colostomy. Overall mortality rate was 9.5%. Three late deaths occurred in the DCL group, and only one death was associated with an anastomotic leak. Performing a DA in DCI during DCL is a reliable and feasible approach as long as severe acidosis, bowel wall edema, and/or persistent intra-abdominal infections are not present.

Full Text Available OBJECTIVE: The purpose of this series is to report our experience in managing ureteral trauma, focusing on the importance of early diagnosis, correct treatment, and the impact of associated injuries on the management and morbid-mortality. MATERIALS AND METHODS: From January 1994 to December 2002, 1487 laparotomies for abdominal trauma were performed and 20 patients with ureteral lesions were identified, all of them secondary to penetrating injury. Medical charts were analyzed as well as information about trauma mechanisms, diagnostic routine, treatment and outcome. RESULTS: All patients were men. Mean age was 27 years. The mechanisms of injury were gunshot wounds in 18 cases (90% and stab wounds in two (10%. All penetrating abdominal injuries had primary indication of laparotomy, and neither excretory urography nor computed tomography were used in any case before surgery. The diagnosis of ureteric injury was made intra-operatively in 17 cases (85%. Two ureteral injuries (10% were initially missed. All patients had associated injuries. The treatment was dictated by the location, extension and time necessary to identify the injury. The overall incidence of complications was 55%. The presence of shock on admission, delayed diagnosis, Abdominal Trauma Index > 25, Injury Severity Score > 25 and colon injuries were associated to a high complication rate, however, there was no statistically significant difference. There were no mortalities in this group. CONCLUSIONS: A high index of suspicion is required for diagnosis of ureteral injuries. A thorough exploration of all retroperitoneal hematoma after penetrating trauma should be an accurate method of diagnosis; even though it failed in 10% of our cases.

The individual chapters reflect ongoing research conducted by the STAB members in the field of numerical and experimental fluid mechanics and aerodynamics, mainly for (but not limited to) aerospace applications, and cover both nationally and EC-funded projects. Special emphasis is given to collaborative research projects conducted by German scientists and engineers from universities, research-establishments and industries. By addressing a number of cutting-edge applications, together with the relevant physical and mathematics fundamentals, the book provides readers with a comprehensive overview of the current research work in the field. Though the book’s primary emphasis is on the aerospace context, it also addresses further important applications, e.g. in ground transportation and energy. .

Polyploidization and cell fusion contribute to wound healing in the adult Drosophila epithelium.

Losick, Vicki P; Fox, Donald T; Spradling, Allan C

2013-11-18

Reestablishing epithelial integrity and biosynthetic capacity is critically important following tissue damage. The adult Drosophila abdominal epithelium provides an attractive new system to address how postmitotic diploid cells contribute to repair. Puncture wounds to the adult Drosophila epidermis close initially by forming a melanized scab. We found that epithelial cells near the wound site fuse to form a giant syncytium, which sends lamellae under the scab to re-epithelialize the damaged site. Other large cells arise more peripherally by initiating endocycles and becoming polyploid, or by cell fusion. Rac GTPase activity is needed for syncytium formation, while the Hippo signaling effector Yorkie modulates both polyploidization and cell fusion. Large cell formation is functionally important because when both polyploidization and fusion are blocked, wounds do not re-epithelialize. Our observations indicate that cell mass lost upon wounding can be replaced by polyploidization instead of mitotic proliferation. We propose that large cells generated by polyploidization or cell fusion are essential because they are better able than diploid cells to mechanically stabilize wounds, especially those containing permanent acellular structures, such as scar tissue.

Peripheral surgical wounding and age-dependent neuroinflammation in mice.

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.

During laparoscopic cholecystectomy, perforation of the gallbladder can occurs in extraction of the gallbladder. The fate of such lost gallstones, which can lead to the formation of an abscess, an abdominal wall mass, or a persistent sinus, has not been studied adequately. Herein we report the case of a persistent sinus of the abdominal wall after an emergent laparoscopic cholecystectomy in an 82-year-old woman with gangrenous cholecystitis and perforation of the friable wall in association with an empyema of the gallbladder. The culture of the obtained pus was positive for Escherichia coli. After a small leak of dirty fluid from the wound of the epigastric port site of 4 months' duration, surgical exploration under local anesthesia revealed that the sinus was caused by spilled gallstones impacting into the abdominal wall between the posterior sheath and left rectus abdominalis muscle. The removal of the stones resulted in complete healing. Long-term complications after laparoscopic cholecystectomy involving the abdominal wall are rare but important possible consequences that could be avoided.

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

Gunshot wounds are rare events in European countries, but stab and impalement injuries occur more frequently and are often spectacular. The aim of the study was to describe several types of penetrating abdomino-thoracic injuries as well as the appropriate surgical interventions, including complex wound management. The representative case series includes four patients with abdomino-thoracic penetrating trauma (two impalements and two stabbings), who were treated in a surgical university hospital (tertiary) centre during a 12-month period. 1. A man was impaled on a steel pipe, which entered the body above the right kidney and behind the liver through the mediastinum via the right thorax, passing the heart and aortic arch up to the left clavicle. The rod was removed via sternotomy and median laparotomy. Only the left subclavian vein required repair. Postoperatively, a residual lesion of the left brachial plexus caused temporary pneumonia. 2. A leg of a collapsing chair drilled into a woman's left foramen obturatorium and exited the body at the right anterior iliac spine. At a regional hospital, the chair leg was removed and the canal caused by gluteal penetration was excised. Exploratory laparotomy revealed peritonitis resulting from a perforated ileum. The injury was repaired with segmental resection and anastomosis. Postoperative right inguinal wound necrosis necessitated excision and vacuum-assisted closure sealing. The patient has residual paresthesia in her left leg resulting from a sacral plexus lesion. 3. During an altercation, a man was stabbed twice in the right thorax. The right pulmonary lobe, the diaphragm, and the liver dome between segment VIII and V were injured. The patient also had a large scalp avulsion at the left and right parietooccipital site and transection of the biceps muscle at the middle third of the right humerus. The chest injuries, approached via right subcostal incision and right anterior thoracotomy were managed with liver packing (two

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

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

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.

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

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

LENUS (Irish Health Repository)

Birindelli, Arianna

2017-01-01

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

Infection of pancreatic necrosis, although present in less than 10% of acute pancreatitis, carries a high risk of mortality; debridment and drainage of necrosis is the treatment of choice, followed by 'open' or 'close' abdomen management. We recently introduced the use of intra-abdominal vacuum sealing after a classic necrosectomy and laparostomy. Two patients admitted to ICU for respiratory insufficiency and a diagnosis of severe acute pancreatitis developed pancreatic necrosis and were treated by necrosectomy, lesser sac marsupialisation and posterior lumbotomic opening. Both of the patients recovered from pancreatitis and a good healing of laparostomic wounds was obtained with the use of the VAC system. Most relevant advantages of this technique seem to be: the prevention of abdominal compartment syndrome, the simplified nursing of patients and the reduction of time to definitive abdominal closure. © 2010 The Authors.

Gash, A E

2006-07-07

The coupling of energetic metallic multilayers (a.k.a. flash metal) with energetic sol-gel synthesis and processing is an entirely new approach to forming energetic devices for several DoD and DOE needs. They are also practical and commercially viable manufacturing techniques. Improved occupational safety and health, performance, reliability, reproducibility, and environmentally acceptable processing can be achieved using these methodologies and materials. The development and fielding of this technology will enhance mission readiness and reduce the costs, environmental risks and the necessity of resolving environmental concerns related to maintaining military readiness while simultaneously enhancing safety and health. Without sacrificing current performance, we will formulate new impact initiated device (IID) compositions to replace materials from the current composition that pose significant environmental, health, and safety problems associated with functions such as synthesis, material receipt, storage, handling, processing into the composition, reaction products from testing, and safe disposal. To do this, we will advance the use of nanocomposite preparation via the use of multilayer flash metal and sol-gel technologies and apply it to new small IIDs. This work will also serve to demonstrate that these technologies and resultant materials are relevant and practical to a variety of energetic needs of DoD and DOE. The goal will be to produce an IID whose composition is acceptable by OSHA, EPA, the Clean Air Act, Clean Water Act, Resource Recovery Act, etc. standards, without sacrificing current performance. The development of environmentally benign stab detonators and igniters will result in the removal of hazardous and toxic components associated with their manufacturing, handling, and use. This will lead to improved worker safety during manufacturing as well as reduced exposure of Service personnel during their storage and or use in operations. 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.

Our aim was to define the epidemiological profile of acute generalized peritonitis in N'Djamena, Chad. This retrospective study, conducted in the general surgery department of the National Reference General Hospital, examined the files of 492 patients who underwent surgery for acute generalized peritonitis from June 2007 to December 2012. Epidemiological, clinical, paraclinical, and therapeutic characteristics were described. Acute generalized peritonitis accounted for 35.2 % of all visceral surgical emergencies. Male patients were at highest risk (sex-ratio 6.5). The patients' mean age was 25.8 years (range 1 to 70 years). All patients had abdominal pain. The leading cause was traumatic visceral perforation by stabbing or a firearm in 226 cases (46 %), followed by diffuse appendiceal peritonitis. Primary peritonitis was rare. The principal procedure was surgical excision and suture. The mean time to consultation was 3 days and the mean hospital stay 8.5 days. The morbidity rate was 16.8 %, dominated by wound infection. The mortality rate was 6.8 %. Abdominal trauma is the major cause of acute generalized peritonitis in N'Djamena. Prognosis depends on time to surgical management.

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.

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.

The objective of this study was to determinate the reliability of 3-dimensional wound analyzer (3-DWMD) in the wound area measurement for animal small area in the process of wound healing. Seven Sprague-Dawley rats were used to establish the skin defect model. And the wound area and time consumption were measured on days 0, 5, 10, 15 using 3-DWMD, investigators, and planimetry method. The measurement results using 3-DWMD and investigators were analyzed comparative with that using planimetry method separately. A total 46 wounds, including 32 irregular wounds and regular 14 wounds, were measured. No matter calculating the irregular wounds or the regular wounds, there was no significant difference between 3-DWMD group and planimetry group in measuring wound area (P > 0.05). However, a statistically significant difference was found in time-consuming for measuring wound area between 3-DWMD group and planimetry group (P area, and its measurement results were consistent with planimetry method. Therefore, such measuring equipment has clinical reference value for measuring precision area of the wound in the process of wound healing.

To evaluate the challenges and outcome of management of large abdominal wall hernias in a resource limited environment and highlight the options available to surgeons in similar conditions. A review of prospectively collected data on large abdominal wall hernias managed between 2003 and 2009. University of Nigeria Teaching Hospital, Enugu, Nigeria and surrounding hospitals. Patients with hernias more than 4 cm in their largest diameter, patients with closely sited multiple hernias or failed previous repairs and in whom the surgeon considers direct repair inappropriate. Demographics of patients with large hernias, methods of hernia repair, recurrences, early and late complications following the repair. There were 41 patients, comprising 28 females and 13 males with ages 14 - 73 years. Most (53.7%) were incisional hernias. Gynecological surgeries (66.7%) were the most common initiating surgeries. Fifteen of the patients (36.6%) have had failed previous repairs, 41.5% were obese, five patients presented with intestinal obstruction. Thirty nine of the hernias were repaired with prolene mesh, one with composite mesh and one by danning technique. Most of the patients had extra peritoneal mesh placement. Three patients needed ventilator support. After a mean follow up of 18.6 months, there was a single failed repair. Two post op deaths were related to respiratory distress. There were 12 wound infection and 8 superficial wound dehiscence, all of which except one resolved with dressing. One reoperation was done following mesh infection and extrusion. Large abdominal wall hernia repair in resource limited environments present several challenges with wound infection and respiratory distress being the most notable. Surgeons who embark on it in these environments must be prepared t o secure the proper tissue replacement materials and have adequate ventilation support.

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.

With the dramatic increase in the aging population, the study and care of wounds in the elderly have become priority topics for both researchers and clinicians. The effects of aging on wound healing in humans have remained controversial. The study was a 5-year epidemiological evaluation of standardized data collected regularly during patients' visits at a specialized Wound Care Center with the aim to determine the key factors influencing the healing of chronic lower extremity wounds. In this analysis of 1,158 chronic wounds, the frequency of wound closure was statistically significantly lower in older patients compared with younger patients. The share of closed wounds decreased by nearly 25% in the elderly patients (>or=70 years). The relationship between the patient's age and the proportion of wound closure was nonlinear. The effect of aging on the frequency of wound closure of chronic wounds became clinically apparent after age 60. The chronicity of the wounds was illustrated by their recurrent nature, their long duration, the presence of multiple wounds, and the frequency of concurrent infection. Comorbidity was documented by the coprevalence of up to three underlying diseases related to impaired wound healing. The present study clearly showed that aging affects chronic wound healing negatively.

Several techniques for temporary abdominal closure have been developed. We systematically review the literature on temporary abdominal closure to ascertain whether the method can be tailored to the indication. Medline, Embase, the Cochrane Central Register of Controlled Trials and relevant meeting abstracts until December 2009 were searched using the following headings: open abdomen, laparostomy, VAC (vacuum assisted closure), TNP (topical negative pressure), fascial closure, temporary abdominal closure, fascial dehiscence and deep wound dehiscence. The data were analysed by closure technique and aetiology. The primary end-points included delayed fascial closure and in-hospital mortality. The secondary end-points were intra-abdominal complications. The search identified 106 papers for inclusion. The techniques described were VAC (38 series), mesh/sheet (30 series), packing (15 series), Wittmann patch (eight series), Bogotá bag (six series), dynamic retention sutures (three series), zipper (15 series), skin only and locking device (one series each). The highest facial closure rates were seen with the Wittmann patch (78%), dynamic retention sutures (71%) and VAC (61%). Temporary abdominal closure has evolved from simple packing to VAC based systems. In the absence of sepsis Wittmann patch and VAC offered the best outcome. In its presence VAC had the highest delayed primary closure and the lowest mortality rates. However, due to data heterogeneity only limited conclusions can be drawn from this analysis. © 2012 The Authors.

Nontraumatic abdominal emergencies: acute abdominal pain: diagnostic strategies

2002-01-01

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

The book demonstrates the potential of this speciality: It has become evident that the combination of diagnostic imaging and forensic medicine solves more cases of death of unknown cause than each alone, and that a radiograph can be read like a document describing forces of modern time and its effects on current society. The posters of 6 exhibitions demonstrate the actual cause of death and its preceding violence. They aim at the medical as well as the interested lay-public: Causes of natural and of violent death become visible. For instance, stab- and gunshot wounds into a person's rear are contradictory of self-defence. Stab wounds with penetration of ribs indicate great force and, therefore, intentional homicide. The same is valid for multiple stabs, stabs through silicon prosthesis of a mammoplasty, and stabs into the breast cage of a defenceless toddler. X-rays of the living can indicate preceding torture. X-rays are part of the security technology employed at airports and countries' borders. They help to detect drugs, explosives, and human stow-aways. The x-ray examination of the deceased visualises success and failure of the preceding therapy. After reanimation, the position of a tracheal tube, the effects of a vascular puncture, and potential fractures of the breast cage can be evaluated. After cardiac and aortic interventions, the procedure of choice and its effects can be seen. Concerning general or intensive care, diagnostic imaging shows the position of urinary catheters, gastric tubes and vascular catheters. Prenatal diagnostic imaging can determine the sex of the foetus and possible malformations; and in peri- and postnatal death, it may show the effects of iatrogenic actions, and later on, of child-abuse.

After reanimation, the position of a tracheal tube, the effects of a vascular puncture, and potential fractures of the breast cage can be evaluated. After cardiac and aortic interventions, the procedure of choice and its effects can be seen. Concerning general or intensive care, diagnostic imaging shows the position of urinary catheters, gastric tubes and vascular catheters. Prenatal diagnostic imaging can determine the sex of the foetus and possible malformations; and in peri- and postnatal death, it may show the effects of iatrogenic actions, and later on, of child-abuse.

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

Randomized controlled trials in wound care generalize poorly because they exclude patients with significant comorbid conditions. Research using real-world wound care patients is hindered by lack of validated methods to stratify patients according to severity of underlying illnesses. We developed a comprehensive stratification system for patients with wounds that predicts healing likelihood. Complete medical record data on 50,967 wounds from the United States Wound Registry were assigned a clear outcome (healed, amputated, etc.). Factors known to be associated with healing were evaluated using logistic regression models. Significant variables (p healing for each wound type. Some variables predicted significantly in nearly all models: wound size, wound age, number of wounds, evidence of bioburden, tissue type exposed (Wagner grade or stage), being nonambulatory, and requiring hospitalization during the course of care. Variables significant in some models included renal failure, renal transplant, malnutrition, autoimmune disease, and cardiovascular disease. All models validated well when applied to the holdout sample. The "Wound Healing Index" can validly predict likelihood of wound healing among real-world patients and can facilitate comparative effectiveness research to identify patients needing advanced therapeutics. © 2013 by the Wound Healing Society.

Obesity is associated to a delayed wound healing and prolonged inflammatory phase. Laser light has shown positive results in the photobiomodulation of tissue repair; however, its use associated with systemic disorders such as obesity is still little explored in the literature. The aim of this study was to validate an experimental system for studying weight gaining by consuming a high fat diet called "cafeteria diet" (CD) for the induction of obesity. Forty-eight rats were weaned, divided into two experimental groups: standard diet (SD) and Cafeteria Diet (CD). Free feeding was carried out during 20 weeks and the mass gaining was accompanied. After general anesthesia standardized surgical wounds were created (1cm2) in the dorsal midline region of each animal. Both groups (SD; CD) were divided into 2 subgroups of 12 animals, G1 and G3 (non-irradiated) and G2 and G4 (irradiated). The irradiation protocols (λ660 nm, 40 mW, CW; 24 J/cm2) started immediately after surgery and were repeated every other day during 14 days. The rats were killed at the 8th or 15th days after surgery. The abdominal fat was removed and weighed to verify the success of the induction technique. The specimens were taken and routinely processed histology (hematoxylin/eosin) was performed. It was concluded that the ingestion of fast-food increased abdominal fat in rats and modified the inflammatory pattern of the healing. Laser phototherapy in the parameters employed decreased inflammatory intensity quickening wound healing in obese rats.

Full Text Available Burn injuries are a leading cause of morbidity including prolonged hospitalization, disfigurement, and disability. Currently there is no Food and Drug Administration-approved burn therapeutics. A clinical distinction of burn injuries from other acute wounds is the event of the so-called secondary burn wound progression within the first week of the injury, in which a burn expands horizontally and vertically from its initial boundary to a larger area. Therefore, an effective therapeutics for burns should show dual abilities to prevent the burn wound progression and thereafter promote burn wound healing. Herein we report that topically applied F-5 fragment of heat shock protein-90α is a dual functional agent to promote burn wound healing in pigs. First, F-5 prevents burn wound progression by protecting the surrounding cells from undergoing heat-induced caspase 3 activation and apoptosis with increased Akt activation. Accordingly, F-5–treated burn and excision wounds show a marked decline in inflammation. Thereafter, F-5 accelerates burn wound healing by stimulating the keratinocyte migration-led reepithelialization, leading to wound closure. This study addresses a topical agent that is capable of preventing burn wound progression and accelerating burn wound healing.

Previous investigations of short-term outcomes after preoperative exposure to biological therapy in inflammatory bowel disease (IBD) were conflicting. The authors aimed to assess postoperative outcomes in patients who underwent abdominal surgery with recent exposure to anti-tumour necrosis factor therapy. A retrospective case-control study with detailed matching was performed for subjects with IBD with and without exposure to biologics within 180 days of abdominal surgery. Postoperative outcomes were compared between the groups. 473 procedures were reviewed consisting of 195 patients with exposure to biologics and 278 matched controls. There were no significant differences in most postoperative outcomes such as: length of stay, fever (≥ 38.5°C), urinary tract infection, pneumonia, bacteraemia, readmission, reoperations and mortality. On univariate analysis, procedures on biologics had more wound infections compared with controls (19% vs 11%; p=0.008), but this was not significant in multivariate analysis. Concomitant therapy with biologics and thiopurines was associated with increased frequencies of urinary tract infections (p=0.0007) and wound infections (p=0.0045). Operations performed ≤ 14 days from last biologic dose had similar rates of infections and other outcomes when compared with those performed within 15-30 days or 31-180 days. Patients with detectable preoperative infliximab levels had similar rates of wound infection compared with those with undetectable levels (3/10 vs 0/9; p=0.21). Preoperative treatment with TNF-α antagonists in patients with IBD is not associated with most early postoperative complications. A shorter time interval from last biological dose is not associated with increased postoperative complications. In most cases, surgery should not be delayed, and appropriate biological therapy may be continued perioperatively.

The abdominal wall is often neglected as a cause of chronic abdominal pain. The aim of this study was to identify chronic abdominal wall pain syndromes, such as anterior cutaneous nerve entrapment syndrome (ACNES), in a patient population diagnosed with functional abdominal pain, including irritable bowel syndrome, using a validated 18-item questionnaire as an identification tool. In this cross-sectional analysis, 4 Dutch primary care practices employing physicians who were unaware of the existence of ACNES were selected. A total of 535 patients ≥18 years old who were registered with a functional abdominal pain diagnosis were approached when they were symptomatic to complete the questionnaire (maximum 18 points). Responders who scored at least the 10-point cutoff value (sensitivity, 0.94; specificity, 0.92) underwent a diagnostic evaluation to establish their final diagnosis. The main outcome was the presence and prevalence of ACNES in a group of symptomatic patients diagnosed with functional abdominal pain. Of 535 patients, 304 (57%) responded; 167 subjects (31%) recently reporting symptoms completed the questionnaire. Of 23 patients who scored above the 10-point cutoff value, 18 were available for a diagnostic evaluation. In half of these subjects (n = 9) functional abdominal pain (including IBS) was confirmed. However, the other 9 patients were suffering from abdominal wall pain syndrome, 6 of whom were diagnosed with ACNES (3.6% prevalence rate of symptomatic subjects; 95% confidence interval, 1.7-7.6), whereas the remaining 3 harbored a painful lipoma, an abdominal herniation, and a painful scar. A clinically relevant portion of patients previously diagnosed with functional abdominal pain syndrome in a primary care environment suffers from an abdominal wall pain syndrome such as ACNES.

Full Text Available The presence of a contaminated surgical field in abdominal wall defects caused by trauma presents a challenge for surgeons. Both primary suture and synthetic meshes are strongly discouraged as surgical treatments in such cases. We describe the use of a porcine dermal collagen (Permacol implant in an eight-year-old patient with multiple injuries. Three months after discharge, the child remains well with good cosmetic results. He is free of pain and has returned to full activity levels with complete wound closure and without any evidence of residual hernia. In conclusion, our experience indicates that the use of Permacol can be considered an efficient technique for reconstructing an infected abdominal wall defect of a pediatric multitrauma patient.

A prospective, randomized and controlled study of prophylactic A.B. was made in 100 patients prior to abdominal surgery. Fifty patients received 3 x 2 g of cefamandole I.V. within 24 hrs, the first dose being given at the time of anesthetic induction. Postoperative infections occurred in 2% of this group. Fifty patients received the association Clindamycin-Tobramycin (clindamycin 600 mg - tobramycin 80 mg/8 hrs) for 24 hrs, the first dose also at the induction of anesthesia. The complication rate in this group was 18%. The difference between those 2 groups is statistically significant (p less than 0.01). Cefamandole used as a prophylactic antibiotic in abdominal surgery reduces the incidence of postoperative wound infections when compared to the association clindamycin-tobramycin.

Chest trauma in childhood is relatively uncommon in clinical practice andhas been the subject of few reports in literature. This study was undertakento examine our experience in dealing with chest trauma in children. This wasa retrospective study of 74 children who sustained chest trauma and werereferred to King Fahd Hospital in Medina over a two-year period. The age,cause of injury, severity of injury, associated extrathoracic injuries,treatment and outcome were analyzed. The median age of patients was nineyears. Fifty-nine of them (80%) sustained blunt trauma in 62% of thechildren, gun shot wounds were seen in five and stab wounds in 10 children.Head injury was the most common injury associated with thoracic trauma andwas seen in 14 patients (19%) and associated intra-abdominal injuries wereseen in nine patients. Chest x-ray of the blunt trauma patients revealedfractured ribs in 24 children, pneumothorax in six, hemothorax in four,hemoneumothorax in three, and pulmonary contusions in 22 patients. Fifty onepercent of children were managed conservatively, 37% required tubethoracostomy, 8% were mechanically ventilated and 4% underwent thoractomy.The prevalence of chest trauma in children due to road traffic accidents ishigh in Saudi Arabia. Head injury is thought to be the most common associatedextrathoracic injuries, however, most of these patients can be managedconservatively. (author)

All over the world, liver trauma occurs as a result of blunt or penetrating abdominal injury. To review the management, morbidity and mortality of liver trauma in our resource-deprived centre, and to see how we can improve these outcomes, our poor facilities notwithstanding. This is a descriptive epidemiology. Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria. Patients who were treated for liver trauma in our centre between 2004 and 2010 were reviewed for aetiology of injury, management, morbidity and mortality. Of the 162 patients who were treated for liver trauma during the period, only 156 patients were recruited into the study. One hundred and nineteen (119) were males and 37 were females. Majority were blunt injuries while others were penetrating injuries. The blunt injuries were usually solitary, affecting only the liver whereas the penetrating injuries occasionally involved both the liver and some other organ(s). The commonest cause of blunt injuries was road traffic accident followed by fall from height. The commonest cause of penetrating injury was gunshot wound, followed by stab wound. Morbidity and mortality following liver trauma can be reduced by applying prompt and appropriate management modalities within the ambit of available resources. However, outcome will improve if adequate facilities are available.

Diabetes insipidus (DI) is a well documented complication observed after traumatic head injuries. We report a case of hyperacute onset DI in a 19-year-old male who sustained a hypothalamic-pituitary injury when he was stabbed in the head with a 30-cm long thin-bladed knife. At CT, our patient showed significant hemorrhagic contusions of the lower hypothalamus. He developed polydipsia, polyuria, and mild hypernatremia in the Emergency Department. Diagnostic digital subtraction angiography showed a hypervascular congestive pituitary gland with prominent draining veins. On the third day his hypernatremia became severe (183mEq/L). He was managed with parenteral fluids and a regimen of intranasal DDAVP (1-desamino 8-d-arginine vasopressin), leading to improved plasmatic sodium levels, urine output, and urinary specific gravity. In patients presenting with hyperacute posttraumatic DI, emergency room physicians and neurosurgeons should rule out direct injury to the hypothalamus and/or the posterior lobe of the pituitary, and initiate early pharmacological treatment.

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

An aortodigestive fistula can be revealed by a peripheral septic wound when patient have aortic endovascular prosthesis. Our clinical case is about a 69-year-old patient with an abscess of the lateral aspect of his left lower limb. He has been treated few years ago for an aorto-abdominal anevrysm by an aortobifemoral prosthesis. In spite of a negative initial assessment for an aortodigestive fistula, anaerobic germs were found into the abscess. The initial treatment associated debridement, negative pressure therapy, dermal substitute and a split thickness skin graft for the loss of cutaneous substance. Months later, in front of an unexplained skin healing delay and fever, we realised new assessment bringing to light an aortodigestive fistula. Furthermore, the local bacterial samples from the wound and the hemocultures found both a lot of Escherichia Coli. The change of the aorto-bifemoral prosthesis and the cure of the aortodigestive fistula allowed the complete healing of the loss of cutaneous substance of the leg. The aortodigestive fistulas have a very high mortality. Because of their difficult diagnosis, their clinical suspicion has to start a complete medical assessment. Every septic wound when patients have vascular prosthesis is suggestive of an aortodigestive fistula. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

Surgical site infections (SSIs), such as wound infection, fascial dehiscence, and intraabdominal abscess, commonly occur following penetrating abdominal trauma. However, most of the literature involves penetrating colon injuries. There are few reports describing complications following penetrating stomach and small bowel injuries. Based on the hypothesis that SSIs are commonly found following penetrating stomach and small bowel trauma, a prospective observational study was performed at an academic Level I trauma center from March 1, 2004 until August 31, 2006. The subjects were patients who had sustained a penetrating injury to the stomach or small bowel. Patients were followed for the development of an SSI, defined as wound infection, fascial dehiscence, or intraabdominal abscess. A total of 178 patients were admitted with penetrating stomach or small bowel injuries over the 29-month period. There were 121 (68%) gunshot injuries and 57 (32%) stab wounds. Associated intraabdominal injuries occurred in 74% of patients. Overall, SSIs occurred in 20% of cases. Risk factors for SSI included associated duodenal or colon injury, whereas time to operating room, blood loss, and type and duration of antibiotic use were not. When associated colon injuries were excluded, SSIs occurred in 16% of patients with gastric injuries and 13% of those with small bowel injuries. SSIs commonly follow penetrating stomach and small bowel trauma. Risk factors for SSI include associated duodenal or colon injury. Delay to operating room, blood loss, and type and length of antibiotic prophylaxis were not associated with an increased risk of SSI.

Post-operative peritoneal adhesions are serious consequences of abdominal or pelvic surgery and cause severe bowel obstruction, chronic pelvic pain and infertility. In this study, a novel nano-hydrogel system based on a monomethoxy poly(ethylene glycol)-poly(lactic acid) (MPEG-PLA) di-block copolymer was studied for its ability to prevent abdominal adhesion in rats. The MPEG-PLA hydrogel at a concentration of 40% (w/v) was injected and was able to adhere to defect sites at body temperature. The ability of the hydrogel to inhibit adhesion of post-operative tissues was evaluated by utilizing a rat model of abdominal sidewall-cecum abrasion. It was possible to heal wounded tissue through regeneration of neo-peritoneal tissues ten days after surgery. Our data showed that this hydrogel system is equally as effective as current commercialized anti-adhesive products.

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

Early osteopathic theory and practice, and the work of the medical intuitive Edgar Cayce suggested that the abdominal areas of individuals with epilepsy would manifest "cold spots." The etiology for this phenomenon was thought to be abdominal adhesions caused by inflammation and viscero-somatic reflexes caused by adhesions or injury to visceral or musculoskeletal system structures. Indeed, until that advent of electroencephalography in the 1930s, medical practice regarding epilepsy focused on abdominal neural and visceral structures. Following two hypotheses were formulated to evaluate any abdominal temperature phenomena: (1) an abdominal quadrant division analysis would find one or more quadrants "colder" in the focal-onset epilepsy group (ICD9-CM 345.4 and 345.5) compared to controls. (2) Total abdominal areas of individuals with focal-onset epilepsy wound be colder than a control group. Overall, 50 patients with the diagnosis of focal-onset epilepsy were recruited from the office of the Epilepsy Foundation of Florida and 50 control subjects with no history of epilepsy were recruited through advertising to the public. Under controlled room conditions all subjects had infrared thermographic images made and recorded by Med-Hot Model MH-731 FLIR equipment. There were no significant demographic difference between experimental patients and control subjects, though the control group tended to be younger and more often male; however, these were controlled for in all analyses. In the quadrant analysis, there were significant differences in that more epileptic patients had colder left upper abdominal quadrant temperatures than the control group (66.8% versus 44.9%; P = .030). In the total abdominal analysis, however, there were no significant differences. The results support the hypothesis that individuals with focal-onset epilepsy have colder abdominal areas. If substantiated in further research, present study results will require further examination of the mechanisms of

Time to definitive care following injury is important to the outcomes of trauma patients. Prehospital trauma care is provided based on policies developed by individual trauma systems and is an important component of the care of injured patients. Given a paucity of systems-level trauma research, considerable variability exists in prehospital care policies across trauma systems, potentially affecting patient outcomes. To evaluate whether private vehicle prehospital transport confers a survival advantage vs ground emergency medical services (EMS) transport following penetrating injuries in urban trauma systems. Retrospective cohort study of data included in the National Trauma Data Bank from January 1, 2010, through December 31, 2012, comprising 298 level 1 and level 2 trauma centers that contribute data to the National Trauma Data Bank that are located within the 100 most populous metropolitan areas in the United States. Of 2 329 446 patients assessed for eligibility, 103 029 were included in this study. All patients were 16 years or older, had a gunshot wound or stab wound, and were transported by ground EMS or private vehicle. In-hospital mortality. Of the 2 329 446 records assessed for eligibility, 103 029 individuals at 298 urban level 1 and level 2 trauma centers were included in the analysis. The study population was predominantly male (87.6%), with a mean age of 32.3 years. Among those included, 47.9% were black, 26.3% were white, and 18.4% were Hispanic. Following risk adjustment, individuals with penetrating injuries transported by private vehicle were less likely to die than patients transported by ground EMS (odds ratio [OR], 0.38; 95% CI, 0.31-0.47). This association remained statistically significant on stratified analysis of the gunshot wound (OR,  0.45; 95% CI, 0.36-0.56) and stab wound (OR,  0.32; 95% CI, 0.20-0.52) subgroups. Private vehicle transport is associated with a significantly lower likelihood of death when compared with

In line with advances in diagnostic methods and expectation of a decrease in the number of negative laparotomies, selective non-operative management of abdominal gunshot wounds has been increasingly used over the last three decades. We aim to detect the possibility of treatment without surgery and present our experience in selected cases referred from Syria to a hospital at the Turkish-Syrian border. Between February 2012 and June 2014, patients admitted with abdominal gunshot wounds were analyzed. Computed tomography was performed for all patients on admission. Patients who were hemodynamically stable and did not have symptoms of peritonitis at the time of presentation were included in the study. The primary outcome parameters were mortality and morbidity. Successful selective non-operative management (Group 1) and unsuccessful selective non-operative management (Group 2) groups were compared in terms of complications, blood transfusion, injury site, injury severity score (ISS), and hospital stay. Of 158 truncal injury patients, 18 were considered feasible for selective non-operative management. Of these, 14 (78%) patients were treated without surgery. Other Four patients were operated upon progressively increasing abdominal pain and tenderness during follow-up. On diagnostic exploration, all of these cases had intestinal perforations. No mortality was observed in selective non-operative management. There was no statistically significant difference between Group 1 and Group 2, in terms of length of hospital stay (96 and 127 h, respectively). Also, there was no difference between groups in terms of blood transfusion necessity, injury site, complication rate, and injury severity score (p>0.05). Decision making on patient selection for selective non-operative management is critical to ensure favorable outcomes. It is not possible to predict the success of selective non-operative management in advance. Cautious clinical examination and close monitoring of these

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

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.

Physicochemical properties of radiation-sterilized honey alginate wound dressing for exudating wounds

Honey is a well-known natural cure in promoting healing of wounds. Alginate, on the other hand, is a polysaccharide with pharmaceutical applications such as wound dressing and control release drugs. Calcium-alginate wound dressings have a gel-forming capability. in that, upon ion exchange between calcium ions in the dressing, and sodium ions in wound fluid, the dressing transforms into a gel. Cross-linked alginate gels can absorb would fluid, and also maintain a moist environment to the wound area. Combined with anti-microbial properties of honey and absorption and gelling properties of alginate, a honey alginate wound dressing is developed and irradiated for sterility. Its physicochemical properties are then analyzed. The honey-alginate wound dressing has lower pH (4.40±0.02) than alginate alone dressings (5.40±0.04) which is more favorable for wound healing. The dressing also has low moisture content (10.25±1.11%). Analysis of moisture vapour transmission rate shows a general increase with time for 48 hours. The wound dressing also has an absorbency of 19.00±1.80 g/100 cm 2 with a gel fraction of 18.44±0.63%. The rate of absorption analysis, meanwhile, shows a very rapid absorption rate upon exposure to wound fluid. After some time, a decrease in rate is observed which is accounted to the release of honey to the wound environment. For tensile strength, irradiation causes an effect in tensile strength in machine direction but is insignificant for cross machine direction. Physicochemical properties of the radiation-sterilized honey alginate wound dressing e.g. acidic pH, absorbency, moisture vapor permeability and absorption rate ascertain its characteristic as a good wound dressing for exudating wounds. Its low moisture content, meanwhile, allows for longer shelf-life of the developed product. (author)

Full Text Available Introduction. Surgery for cardiac trauma is considered fatal and for wounds of the colon by associated sepsis is normally considered; however, conservative management of many traumatic lesions of different injured organs has progressed over the years. Presentation of the Case. A 65-year-old male patient presented with multiple shotgun wounds on the left upper limb, thorax, and abdomen. On evaluation, he was hemodynamically stable with normal sinus rhythm and normal blood pressure, no dyspnea, or abdominal pain. Computed tomography (CT scan of the chest shows hematoma around the aorta without injury to the blood vessel wall with an intramyocardial projectile without pericardial effusion. CT scan of the abdomen showed pellets in the transverse colon and descending colon endoluminal without extravasation of contrast medium or intra-abdominal fluid. The patient remains hemodynamically stable, and nonsurgical procedure was established. Discussion. Patients with asymptomatic intramyocardial projectiles can be safely managed without surgery. Nonsurgical management is only possible in asymptomatic patients with trauma of the colon through close surveillance and with very selective patients since standard management is surgery. Conclusion. Nonsurgical management of cardiac trauma, as well as colon penetrating trauma, can be performed in carefully selected patients with proper clinical follow-up, imaging, and laboratory studies.

Full Text Available Wound healing represents a complex biological repair process. Established 2D monolayers and wounding techniques investigate cell migration, but do not represent coordinated multi-cellular systems. We aim to use wound surface area measurements obtained from image acquisition and planimetry systems to establish our wounding technique and in vitro organotypic tissue. These systems will be used in our future wound healing treatment studies to assess the rate of wound closure in response to wound healing treatment with light therapy (photobiomodulation. The image acquisition and planimetry systems were developed, calibrated, and verified to measure wound surface area in vitro. The system consists of a recording system (Sony DSC HX60, 20.4 M Pixel, 1/2.3″ CMOS sensor and calibrated with 1mm scale paper. Macro photography with an optical zoom magnification of 2:1 achieves sufficient resolution to evaluate the 3mm wound size and healing growth. The camera system was leveled with an aluminum construction to ensure constant distance and orientation of the images. The JPG-format images were processed with a planimetry system in MATLAB. Edge detection enables definition of the wounded area. Wound area can be calculated with surface integrals. To separate the wounded area from the background, the image was filtered in several steps. Agar models, injured through several test persons with different levels of experience, were used as pilot data to test the planimetry software. These image acquisition and planimetry systems support the development of our wound healing research. The reproducibility of our wounding technique can be assessed by the variability in initial wound surface area. Also, wound healing treatment effects can be assessed by the change in rate of wound closure. These techniques represent the foundations of our wound model, wounding technique, and analysis systems in our ongoing studies in wound healing and therapy.

Gastrectomy remains the primary therapeutic method for resectable gastric cancer. Thought of as an important measure to reduce post-operative complications and mortality, abdominal drainage has been used widely after gastrectomy for gastric cancer in previous decades. The benefits of abdominal drainage have been questioned by researchers in recent years. The objectives of this review were to assess the benefits and harms of routine abdominal drainage post-gastrectomy for gastric cancer. We searched the Cochrane Upper Gastrointestinal and Pancreatic Diseases (UGPD) Group Specialised Register and the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2014, Issue 11); MEDLINE (via PubMed) (1950 to November 2014); EMBASE (1980 to November 2014); and the Chinese National Knowledge Infrastructure (CNKI) Database (1979 to November 2014). We included randomised controlled trials (RCTs) comparing an abdominal drain versus no drain in patients who had undergone gastrectomy (not considering the scale of gastrectomy and the extent of lymphadenectomy); irrespective of language, publication status, and the type of drain. We excluded RCTs comparing one drain with another. We adhered to the standard methodological procedures of The Cochrane Collaboration. From each included trial, we extracted the data on the methodological quality and characteristics of the participants, mortality (30-day mortality), re-operations, post-operative complications (pneumonia, wound infection, intra-abdominal abscess, anastomotic leak, drain-related complications), operation time, length of post-operative hospital stay, and initiation of a soft diet. For dichotomous data, we calculated the risk ratio (RR) and 95% confidence interval (CI). For continuous data, we calculated mean difference (MD) and 95% CI. We tested heterogeneity using the Chi(2) test. We used a fixed-effect model for data analysis with RevMan software, but we used a random-effects model if the P value of

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.

Following confirmation of the presence of biofilms in chronic wounds, the term biofilm became a buzzword within the wound healing community. For more than a century pathogens have been successfully isolated and identified from wound specimens using techniques that were devised in the nineteenth...... extracellular polymeric substances (EPS). Cells within such aggregations (or biofilms) display varying physiological and metabolic properties that are distinct from those of planktonic cells, and which contribute to their persistence. There are many factors that influence healing in wounds and the discovery...... of biofilms in chronic wounds has provided new insight into the reasons why. Increased tolerance of biofilms to antimicrobial agents explains the limited efficacy of antimicrobial agents in chronic wounds and illustrates the need to develop new management strategies.

Optimal treatment for large diabetic foot wounds is ill defined. The purpose of this study was to compare the rate of wound healing with the Vacuum Assisted Closure device trade mark (VAC) to conventional moist dressings in the treatment of large diabetic foot wounds. Diabetics with significant soft tissue defects of the foot were considered for enrollment. Patients were randomized to receive either moist gauze dressings or VAC treatments for 2 weeks, after which they were treated with the alternative dressing for an additional 2 weeks. Wounds were photographed weekly and wound dimensions calculated in a blinded fashion with spatial analysis software. Percent change in wound dimensions were calculated and compared for each weekly assessment and over 2 weeks of therapy with each dressing type. Ten patients were enrolled in the trial, but two were lost to follow-up and two were withdrawn. Complete data were available for analysis on seven wounds in six patients. Average length, width, and depth of the wounds at initiation of the trial was 7.7, 3.5, and 3.1 cm, respectively. Only the wound depth was significantly decreased over the weeks of the trial to 1.2 cm ( p VAC dressings decreased the wound volume and depth significantly more than moist gauze dressings (59% vs. 0% and 49% vs. 8%, respectively). VAC dressings were associated with a decrease in all wound dimensions while wound length and width increased with moist dressings. In summary, over the first several weeks of therapy, VAC dressings decreased wound depth and volume more effectively than moist gauze dressings. Negative-pressure wound treatment may accelerate closure of large foot wounds in the diabetic patient.

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.

Innate defense regulator peptide 1018 in wound healing and wound infection.

Directory of Open Access Journals (Sweden)

Lars Steinstraesser

Full Text Available Innate defense regulators (IDRs are synthetic immunomodulatory versions of natural host defense peptides (HDP. IDRs mediate protection against bacterial challenge in the absence of direct antimicrobial activity, representing a novel approach to anti-infective and anti-inflammatory therapy. Previously, we reported that IDR-1018 selectively induced chemokine responses and suppressed pro-inflammatory responses. As there has been an increasing appreciation for the ability of HDPs to modulate complex immune processes, including wound healing, we characterized the wound healing activities of IDR-1018 in vitro. Further, we investigated the efficacy of IDR-1018 in diabetic and non-diabetic wound healing models. In all experiments, IDR-1018 was compared to the human HDP LL-37 and HDP-derived wound healing peptide HB-107. IDR-1018 was significantly less cytotoxic in vitro as compared to either LL-37 or HB-107. Furthermore, administration of IDR-1018 resulted in a dose-dependent increase in fibroblast cellular respiration. In vivo, IDR-1018 demonstrated significantly accelerated wound healing in S. aureus infected porcine and non-diabetic but not in diabetic murine wounds. However, no significant differences in bacterial colonization were observed. Our investigation demonstrates that in addition to previously reported immunomodulatory activities IDR-1018 promotes wound healing independent of direct antibacterial activity. Interestingly, these effects were not observed in diabetic wounds. It is anticipated that the wound healing activities of IDR-1018 can be attributed to modulation of host immune pathways that are suppressed in diabetic wounds and provide further evidence of the multiple immunomodulatory activities of IDR-1018.

Bullet embolization to the external iliac artery after gunshot injury to the abdominal aorta: a case report

Directory of Open Access Journals (Sweden)

Jaha Luan

2011-08-01

Full Text Available Abstract Introduction Abdominal vascular trauma is fairly common in modern civilian life and is a highly lethal injury. However, if the projectile is small enough, if its energy is diminished when passing through the tissue and if the arterial system is elastic enough, the entry wound into the artery may close without exsanguination and therefore may not be fatal. A projectile captured may even travel downstream until it is arrested by the smaller distal vasculature. The occurrence of this phenomenon is rare and was first described by Trimble in 1968. Case presentation Here we present a case of a 29-year-old Albanian man who, due to a gunshot injury to the back, suffered fracture of his twelfth thoracic and first lumbar vertebra, injury to the posterior wall of his abdominal aorta and then bullet embolism to his left external iliac artery. It is interesting that the signs of distal ischemia developed several hours after the exploratory surgery, raising the possibility that the bullet migrated in the interim or that there was a failure to recognize it during the exploratory surgery. Conclusion In all cases where there is a gunshot injury to the abdomen or chest without an exit wound and with no projectile in the area, there should be a high index of suspicion for possible bullet embolism, particularly in the presence of the distal ischemia.

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.

Profiling wound healing with wound effluent: Raman spectroscopic indicators of infection

The care of modern traumatic war wounds remains a significant challenge for clinicians. Many of the extremity wounds inflicted during Operation Enduring Freedom and Operation Iraqi Freedom are colonized or infected with multi-drug resistant organisms, particularly Acinetobacter baumannii. Biofilm formation and resistance to current treatments can significantly confound the wound healing process. Accurate strain identification and targeted drug administration for the treatment of wound bioburden has become a priority for combat casualty care. In this study, we use vibrational spectroscopy to examine wound exudates for bacterial load. Inherent chemical differences in different bacterial species and strains make possible the high specificity of vibrational spectroscopy.

Morel-Lavallee lesions (MLLs) are rare internal degloving injuries typically caused by blunt traumatic injuries and most commonly occur around the hips and in association with pelvic or acetabular fractures. MLL is often overlooked in the setting of poly-trauma; therefore, clinicians must maintain a high degree of suspicion and be familiar with the management of such injuries, especially in obese poly-trauma patients. We present a 30-year-old female pedestrian struck by a motor vehicle who sustained multiple long bone fractures, a mesenteric hematoma, and full-thickness abdominal skin friction burn which masked a significant underlying abdominal MLL. The internal degloving caused significant devascularization of the overlying soft tissue and skin which required surgical drainage of hematoma, abdominal wall reconstruction with tangential excision, allografting, negative pressure wound therapy, and ultimately autografting. MLL is a rare, often overlooked, internal degloving injury. Surgeons must maintain a high index of suspicion when dealing with third degree friction burns as they may mask underlying injuries such as MLL, and a delay in diagnosis can lead to increased morbidity.

High-energy non-missile penetrating injuries (stab injuries) account for a small percentage of penetrating head injuries and they present a series of special features. A 35-year-old man suffered orbito-frontal? and trans-cranial injuries after falling five meters from a terrace onto a rod iron fence. The removal of the metal rod was performed outside the operating room. The orbital roof was exposed and repaired through a bifrontal craniotomy and the frontal sinuses were cranialised. The orbital floor and zygoma were plated with micro-screws. The patient recovered without significant complications, apart from a slight paresis of the right superior rectus; the ocular globe remained intact.The positive outcome obtained in this very challenging case is attributable to the competency of the Neurotrauma Unit and to the use of a synergistic approach which involved the contribution of neurosurgeons, maxillo-facial surgeons, radiologists and anaesthesiologists.

Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. In this report are examined the clinical and radiological findings of personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. It will also tried to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. In the last seven years it was retrospectively reviewed 31 cases of penetrating liver trauma. The patients were 19 men and 12 women, ranging in age 18 to 73 (mean 42), with penetrating liver injuries from firearms (16 patients) and stab (9 cases) wounds; 6 patients had injuries from different cases. Abdominal CT was carried out in emergency with the CT Angiography (CTA) technique in all patients. In the patients with suspected chest and abdomen involvement CT was performed from the mid-chest for accurate assessment of diaphragm and lung bases and to exclude associated pleuropulmonary damage. Penetrating liver wounds were caused by firearms in 70% of cases, by stabbing in 12% and, in the extant 18%, by other cases such as home accidents, road and work traumas, and liver biopsy. In this series, the liver was most frequently involved, especially by firearms wounds; in the 16 cases the most frequent injuries were hemorrhagic tears. It was found bullets in the liver in 6 cases. In one case of home accident the patient wounded himself while slicing bread with a long knife, which cut into the anterior abdominal wall and tore the anterior liver capsule, as seen at CTA. Penetrating wounds to liver and abdomen are less frequent than those to the chest. In the past decade the use of CT has changed the diagnostic and therapeutic approach to such injuries completely, decreasing the resort to explorative laparotomy and hepatorrhaphy. Indeed, CT provides a clear picture of

Since its discovery approximately 200 years ago, chitosan, as a cationic natural polymer, has been widely used as a topical dressing in wound management owing to its hemostatic, stimulation of healing, antimicrobial, nontoxic, biocompatible and biodegradable properties. This article covers the antimicrobial and wound-healing effects of chitosan, as well as its derivatives and complexes, and its use as a vehicle to deliver biopharmaceuticals, antimicrobials and growth factors into tissue. Studies covering applications of chitosan in wounds and burns can be classified into in vitro, animal and clinical studies. Chitosan preparations are classified into native chitosan, chitosan formulations, complexes and derivatives with other substances. Chitosan can be used to prevent or treat wound and burn infections not only because of its intrinsic antimicrobial properties, but also by virtue of its ability to deliver extrinsic antimicrobial agents to wounds and burns. It can also be used as a slow-release drug-delivery vehicle for growth factors to improve wound healing. The large number of publications in this area suggests that chitosan will continue to be an important agent in the management of wounds and burns. PMID:21810057

Saliva and wound healing.

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.

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.

A novel rapid hemostatic and mild polyurethane-urea foam (PUUF) wound dressing was prepared by the particle leaching method and vacuum freeze-drying method using 4, 4-Methylenebis(cyclohexyl isocyanate), 4,4-diaminodicyclohexylmethane and poly (ethylene glycol) as raw materials. And X-ray diffraction (XRD), tensile test, differential scanning calorimetry (DSC) and thermogravimetry (TG) were used to its crystallinity, stress and strain behavior, and thermal properties, respectively. Platelet adhesion, fibrinogen adhesion and blood clotting were performed to evaluate its hemostatic effect. And H&E staining and Masson Trichrome staining were used to its wound healing efficacy. The results revealed the pore size of PUUF is 50–130 μm, and its porosity is 71.01%. Porous PUUF exhibited good water uptake that was benefit to adsorb abundant wound exudates to build a regional moist environment beneficial for wound healing. The PUUF wound dressing exhibit better blood coagulation effect than commercial polyurethane dressing (CaduMedi). Though both PUUF and CaduMedi facilitated wound healing generating full re-epithelialization within 13 days, PUUF was milder and lead to more slight inflammatory response than CaduMedi. In addition, PUUF wound dressing exhibited lower cytotoxicity than CaduMedi against NIH3T3 cells. Overall, porous PUUF represents a novel mild wound dressing with excellent water uptake, hemostatic effect and low toxicity, and it can promote wound healing and enhance re-epithelialization. - Highlights: • Rapid hemostatic and mild PUUF wound dressing was fabricated. • Low-toxic PUUF exhibited good water uptake that could build a regional moist environment beneficial for wound healing. • PUUF could promote wound healing and enhance re-epithelialization.

This article reports the outcomes of the use of Surgihoney RO (SHRO), topical wound dressing in a multi-centre, international setting. The aims were to explore the clinical effects of SHRO, including a reduction in bacterial load and biofilm and improvement in healing in a variety of challenging non-healing and clinically infected wounds. This was a non-comparative evaluation, where both acute and chronic wounds with established delayed healing were treated with the dressing. Clinicians prospectively recorded wound improvement or deterioration, level of wound exudate, presence of pain, and presence of slough and necrosis. Analysis of this data provided information on clinical performance of the dressing. Semi-quantitative culture to assess bacterial bioburden was performed where possible. We recruited 104 patients, mean age 61 years old, with 114 wounds. The mean duration of wounds before treatment was 3.7 months and the mean duration of treatment was 25.7 days. During treatment 24 wounds (21%) healed and the remaining 90 (79%) wounds improved following application of the dressing. No deterioration in any wound was observed. A reduction in patient pain, level of wound exudate and in devitalised tissue were consistently reported. These positive improvements in wound progress were reflected in the wound cultures that showed a reduction in bacterial load in 39 out of the 40 swabs taken. There were two adverse events recorded: a stinging sensation following application of the dressing was experienced by 2 patients, and 2 elderly patients died of causes unrelated to the dressing or to the chronic wound. These patients' wounds and their response to SHRO have been included in the analysis. SHRO was well tolerated and shows great promise as an effective potent topical antimicrobial in the healing of challenging wounds. Matthew Dryden has become a shareholder in Matoke Holdings, the manufacturer of Surgihoney RO, since the completion of this study. Keith Cutting is a

Little is known about wound healing in psoriasis. We performed a cohort study examining differences in wound healing complications between patients with and without psoriasis. Psoriasis patients with traumatic wounds were matched 1:3 to non-psoriasis patients with traumatic wounds based on age, gender, and body mass index (BMI). We examined theincidence of wound complications including infection, necrosis, and hematoma as well as incident antibiotic use within three months following diagnosis of a traumatic wound. The study included 164 patients with traumatic wounds, comprised of 41 patients with psoriasis matched to 123 patients without psoriasis. No statistically significant differences were detected in the incidence of overall wound complications between wound patients with psoriasis and wound patients without psoriasis (14.6% versus. 13.0%, HR 1.18, CI 0.39-3.56). After adjustment for diabetes, peripheral vascular disease, and smoking, no statistically significant differences were detected in the incidence of overall wound complications between patients with and without psoriasis (HR 1.11, CI 0.34-3.58). Specifically, the adjusted rates of antibiotic use were not significantly different between those with and without psoriasis (HR 0.65, CI 0.29-1.46). The incidence of wound complications following traumatic wounds of the skin was found to be similar between patients with and without psoriasis.

We report on our experience with routine abdominal ultrasonography in 120 children (aged 3-15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n...... = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. CONCLUSION: The diagnostic value of abdominal ultrasonography in unselected children with recurrent abdominal pain is low. However, the direct visualization...... of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain....

The plain abdominal x-ray is still the first imaging modality in diagnosis of acute abdomen. The aim of this study was to find the value of plain abdominal x-ray in the management of abdominal emergencies seen in Lagos university teaching hospital. The accurate diagnosis of the cause of acute abdominal pain is one of the most challenging undertakings in emergency medicine. This is due to overlapping of clinical presentation and non-specific findings of physical and even laboratory data of the multifarious causes. Plain abdominal radiography is one investigation that can be obtained readily and within a short period of time to help the physician arrive at a correct diagnosis The relevance of plain abdominal radiography was therefore evaluated in the management of abdominal emergencies seen in Lagos over a 12 month period (April 2002 to March 2003). A prospective study of 100 consecutively presenting patients with acute abdominal conditions treated by the general surgical unit of Lagos University Teaching Hospital was undertaken. All patients had supine and erect abdominal x-ray before any therapeutic intervention was undertaken. The diagnostic features of the plain films were compared with final diagnosis to determine the usefulness of the plain x-ray There were 54 males and 46 females (M:F 1.2:1). Twenty-four percent of the patients had intestinal obstruction, 20% perforated typhoid enteritis; gunshot injuries and generalized peritonitis each occurred in 13%, blunt abdominal trauma in 12%, while 8% and 10% had acute appendicitis and perforated peptic ulcer disease respectively. Of 100 patients studied, 54% had plain abdominal radiographs that showed positive diagnostic features. Plain abdominal radiograph showed high sensitivity in patients with intestinal obstruction 100% and perforated peptic ulcer 90% but was less sensitive in patients with perforated typhoid, acute appendicitis, and blunt abdominal trauma and generalized peritonitis. In conclusion, this study

Abdominal aortic aneurysms and abdominal hernias become an important health problems of our times. Abdominal aortic aneurysm and its rupture is one of the most dangerous fact in vascular surgery. There are some theories pointing to a multifactoral genesis of these kinds of diseases, all of them assume the attenuation of abdominal fascia and abdominal aortic wall. The density and continuity of these structures depend on collagen and elastic fibers structure. Reducing the strength of the fibers may be due to changes in the extracellular matrix (ECM) by the proteolytic enzymes-matrix metalloproteinases (MMPs) that degrade extracellular matrix proteins. These enzymes play an important role in the development of many disease: malignant tumors (colon, breast, lung, pancreas), cardiovascular disease (myocardial infarction, ischemia-reperfusion injury), connective tissue diseases (Ehler-Danlos Syndrome, Marfan's Syndrome), complications of diabetes (retinopathy, nephropathy). One of the most important is matrix metalloproteinase-2 (MMP-2). The aim of the study was an estimation of the MMP-2 blood levels in patients with abdominal aortic aneurysm and primary abdominal hernia, and in patients with only abdominal aortic aneurysm. The study involved 88 patients aged 42 to 89 years, including 75 men and 13 women. Patients were divided into two groups: patients with abdominal aortic aneurysm and primary abdominal hernia (45 persons, representing 51.1% of all group) and patients with only abdominal aortic aneurysm (43 persons, representing 48,9% of all group). It was a statistically significant increase in MMP-2 blood levels in patients with abdominal aortic aneurysm and primary abdominal hernia compared to patients with only abdominal aortic aneurysm. It was a statistically significant increase in the prevalence of POCHP in patients with only abdominal aortic aneurysm compared to patients with abdominal aortic aneurysm and primary abdominal hernia. Statistically significant

The management of colon injuries has distinctly evolved over the last three decades. However, trauma surgeons often find themselves in a dilemma, whether to perform a diversion or to perform a primary repair. The purpose of this study is to evaluate risk factors in colon injury management and their influence on abdominal complications. This is a prospective study conducted at a national level I trauma center in Tirana, Albania from January 2009 to December 2012. The data with respect to demographics, physiological risk factors, intraoperative findings, and surgical procedures were collected. Colonic injury-related morbidity and mortality were analyzed. Multivariate logistic regression analysis was performed by assessing the influence of risk factors on abdominal complications. Of the 157 patients treated with colon injury, was performed a primary repair in 107 (68.15%) of the patients and a diversion in the remaining 50 (31.85%). The mean PATI was 18.6, while 37 (23.6%) of patients had PATI greater than 25. The complications and their frequencies according to the surgical technique used (primay repair vs diversion respectively) includes: wound infections (9.3% vs 50%), anastomotic leak (1.8% vs 8.7%), and intra-abdominal abscess (1.8% vs 6.5%). The multivariate analysis identified two independent risk factors for abdominal complications: transfusions of 4 units of blood within the first 24 hours (OR = 1.2 95% CI (1.03 - 1.57) p =0.02), and diversion (OR = 9.6, 95% CI 4.4 - 21.3, pcolon injuries are both independent risk factors for abdominal complications. The socioeconomic impact and the need for a subsequent operation in colostomy patients are strong reasons to consider primary repair in the management of colon injuries.

Full Text Available Abstract Background Abdominal surgical site infections are among the most common complications of inpatient admissions and have serious consequences for outcomes and costs. Different risk factors may be involved, including age, sex, nutrition and immunity, prophylactic antibiotics, operation type and duration, type of shaving, and secondary infections. This study aimed to determine the risk factors affecting abdominal surgical site infections and their incidence at Imam Khomeini, a major referral teaching hospital in Iran. Methods Patients (n = 802 who had undergone abdominal surgery were studied and the relationships among variables were analyzed by Student's t and Chi-square tests. The subjects were followed for 30 days and by a 20-item questionnaire. Data were collected through pre- and post-operative examinations and telephone follow-ups. Results Of the 802 patients, 139 suffered from SSI (17.4%. In 40.8% of the cases, the wound was dirty infected. The average age for the patients was 46.7 years. The operations were elective in 75.7% of the cases and 24.7% were urgent. The average duration of the operation was 2.24 hours, the average duration of pre-operative hospital stay 4.31 days and the average length of (pre- and post-operation hospital stay 11.2 days. Three quarters of the cases were shaved 12 hours before the operation. The increased operation time, increased bed stay, electivity of the operation, septicity of the wound, type of incision, the administration of prophylactic antibiotic, type of operation, background disease, and the increased time lapse between shaving and operation all significantly associated with SSI with a p-value less than 0.001. Conclusion In view of the high rate of SSI reported here (17.4% compared with the 14% quoted in literature, this study suggests that by reducing the average operation time to less than 2 hours, the average preoperative stay to 4 days and the overall stay to less than 11 days, and

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.

Since 2007, Ciudad Juárez, Chihuahua has been considered as one of the most violent cities in the world. The General Hospital in this city is the main facility where patients with gunshot wounds are taken. The increased number of admissions of patients with these injuries to many hospitals in the country deserves special attention, as it has an impact on hospital resources and management protocols. To disseminate the epidemiology of fractures caused by gunshot wounds and the hospital care of these patients. A retrospective, observational cohort study was conducted of patients admitted to the Traumatology and Orthopedics Service, Cd. Juárez General Hospital, in Chihuahua, Mexico, from January 2008 to December 2010. All of them sustained fractures resulting from gunshot wounds. A total of 1281 patients with a diagnosis of gunshot wounds were admitted to the hospital; 402 of them were included in this study with 559 fractures; 329 were males and 73 females. Of the 559 fractures, 257 involved the upper limb, 294 the lower limb, and 8 the pelvis. Gunshot wounds-related fractures were classified according to the Gustilo classification. Seventy-nine patients had grade I fractures, 302 grade III, and 21 patients had both grades. Conservative treatment was used in 44.3% of fractures and osteosynthesis in 55%. One patient underwent amputation upon admission. The most widely used osteosynthesis methods were external fixator (37%), straight plates (21%) and intramedullary nail (17%). Five patients (1.3%) underwent amputation: two with femur fracture and 3 with humeral fracture. There were 27 deep infections (6%); one of them resulted in late amputation of the pelvic limb. The most common associated injuries included: chest injuries in 20 patients and abdominal injuries in 17. The range of hospital stay was 1-18 days, with a mean stay of 11 days. The overall mortality rate considering the total number of patients admitted (1,281) was 99 patients (7.72%). From 2006 to 2010 the

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)

Factors Affecting Wound Healing

Guo, S.; DiPietro, L.A.

2010-01-01

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

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.

Disabling Orthostatic Headache after Penetrating Stonemason Pencil Injury to the Sacral Region

2015-01-01

Full Text Available Penetrating injuries to the spine, although less common than motor vehicle accidents and falls, are important causes of injury to the spinal cord. They are essentially of two varieties: gunshot or stab wounds. Gunshot injuries to the spine are more commonly described. Stab wounds are usually inflicted by knife or other sharp objects. Rarer objects causing incidental spinal injuries include glass fragments, wood pieces, chopsticks, nailguns, and injection needles. Just few cases of penetrating vertebral injuries caused by pencil are described. The current case concerns a 42-year-old man with an accidental penetrating stonemason pencil injury into the vertebral canal without neurological deficit. After the self-removal of the foreign object the patient complained of a disabling orthostatic headache. The early identification and treatment of the intracranial hypotension due to the posttraumatic cerebrospinal fluid (CSF sacral fistulae were mandatory to avoid further neurological complications. In the current literature acute pattern of intracranial hypotension immediately after a penetrating injury of the vertebral column has never been reported.

Intra-abdominal surgical intervention can cause the development of intra-peritoneal adhesions. To reduce this problem, different agents have been tested to minimize abdominal adhesions; however, the optimal adhesion prophylaxis has not been found so far. Therefore, the A-Part(®) Gel was developed as a barrier to diminish postsurgical adhesions; the aim of this randomized controlled study was a first evaluation of its safety and efficacy. In this prospective, controlled, randomized, patient-blinded, monocenter phase I-II study, 62 patients received either the hydrogel A-Part-Gel(®) as an anti-adhesive barrier or were untreated after primary elective median laparotomy. Primary endpoint was the occurrence of peritonitis and/or wound healing impairment 28 ± 10 days postoperatively. As secondary endpoints anastomotic leakage until 28 days after surgery, adverse events and adhesions were assessed until 3 months postoperatively. A lower rate of wound healing impairment and/or peritonitis was observed in the A-Part Gel(®) group compared to the control group: (6.5 vs. 13.8 %). The difference between the two groups was -7.3%, 90 % confidence interval [-20.1, 5.4 %]. Both treatment groups showed similar frequency of anastomotic leakage but incidence of adverse events and serious adverse events were slightly lower in the A-Part Gel(®) group compared to the control. Adhesion rates were comparable in both groups. A-Part Gel(®) is safe as an adhesion prophylaxis after abdominal wall surgery but no reduction of postoperative peritoneal adhesion could be found in comparison to the control group. This may at least in part be due to the small sample size as well as to the incomplete coverage of the incision due to the used application. NCT00646412.

It is important for caregivers and patients to know which wounds are at risk of prolonged wound healing to enable timely communication and treatment. Available prognostic models predict wound healing in chronic ulcers, but not in acute wounds, that is, originating after trauma or surgery. We developed a model to detect which factors can predict (prolonged) healing of complex acute wounds in patients treated in a large wound expertise centre (WEC). Using Cox and linear regression analyses, we determined which patient- and wound-related characteristics best predict time to complete wound healing and derived a prediction formula to estimate how long this may take. We selected 563 patients with acute wounds, documented in the WEC registry between 2007 and 2012. Wounds had existed for a median of 19 days (range 6-46 days). The majority of these were located on the leg (52%). Five significant independent predictors of prolonged wound healing were identified: wound location on the trunk [hazard ratio (HR) 0·565, 95% confidence interval (CI) 0·405-0·788; P = 0·001], wound infection (HR 0·728, 95% CI 0·534-0·991; P = 0·044), wound size (HR 0·993, 95% CI 0·988-0·997; P = 0·001), wound duration (HR 0·998, 95% CI 0·996-0·999; P = 0·005) and patient's age (HR 1·009, 95% CI 1·001-1·018; P = 0·020), but not diabetes. Awareness of the five factors predicting the healing of complex acute wounds, particularly wound infection and location on the trunk, may help caregivers to predict wound healing time and to detect, refer and focus on patients who need additional attention. © 2013 The Authors.

Objective: To evaluate the role of focussed abdominal sonography for trauma in blunt paediatric abdominal trauma patients, and to see if the role of computed tomography scan could be limited to only those cases in which sonography was positive. Methods: The retrospective study covered 10 years, from January 1, 2000 to December 31, 2009, and was conducted at the Department of Radiology and Department of Emergency Medicine, Aga Khan University Hospital, Karachi. It comprised cases of 174 children from birth to 14 years who had presented with blunt abdominal trauma and had focussed abdominal sonography for trauma done at the hospital. The findings were correlated with computed tomography scan of the abdomen and clinical follow-up. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of focussed abdominal sonography for trauma were calculated for blunt abdominal trauma. SPSS 17 was used for statistical analysis. Results: Of the total 174 cases, 31 (17.81%) were later confirmed by abdominal scan. Of these 31 children, sonography had been positive in 29 (93.54%) children. In 21 (67.74%) of the 31 children, sonography had been true positive; 8 (25%) (8/31) were false positive; and 2 (6%) (2/31) were false negative. There were 6 (19.3%) children in which sonography was positive and converted to laparotomy. There was no significant difference on account of gender (p>0.356). Focussed abdominal sonography for trauma in the study had sensitivity of 91%, specificity of 95%, positive predictive value of 73%, and negative predictive value of 73% with accuracy of 94%. All patients who had negative sonography were discharged later, and had no complication on clinical follow-up. Conclusions: Focussed abdominal sonography for trauma is a fairly reliable mode to assess blunt abdominal trauma in children. It is a useful tool to pick high-grade solid and hollow viscous injury. The results suggest that the role of computed tomography scan can be

Full Text Available Abdominal elephantiasis is a rare entity. Abdominal elephantiasis is an uncommon, but deformative and progressive cutaneous disease caused by chronic lymphedema and recurrent streptococcal or Staphylococcus infections of the abdominal wall. We present 3 cases of patients with morbid obesity who presented to our hospital with abdominal wall swelling, thickening, erythema, and pain. The abdominal wall and legs were edematous, with cobblestone-like, thickened, hyperpigmented, and fissured plaques on the abdomen. Two patients had localised areas of skin erythema, tenderness, and increased warmth. There was purulent drainage from the abdominal wall in one patient. They were managed with antibiotics with some initial improvement. Meticulous skin care and local keratolytic treatment for the lesions were initiated with limited success due to their late presentation. All three patients refused surgical therapy. Conclusion. Early diagnosis is important for the treatment of abdominal elephantiasis and prevention of complications.

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

Child with Abdominal Pain.

Abdominal pain is one of the common symptoms reported by children in urgent care clinics. While most children tend to have self-limiting conditions, the treating pediatrician should watch out for underlying serious causes like intestinal obstruction and perforation peritonitis, which require immediate referral to an emergency department (ED). Abdominal pain may be secondary to surgical or non-surgical causes, and will differ as per the age of the child. The common etiologies for abdominal pain presenting to an urgent care clinic are acute gastro-enteritis, constipation and functional abdominal pain; however, a variety of extra-abdominal conditions may also present as abdominal pain. Meticulous history taking and physical examination are the best tools for diagnosis, while investigations have a limited role in treating benign etiologies.

Colostomy and drainage for civilian rectal injuries: is that all?

Burch, J M; Feliciano, D V; Mattox, K L

One hundred consecutive patients with injuries to the extraperitoneal rectum were treated over a ten-year period at an urban trauma center. The mechanisms of injury included firearms in 82 patients, stab wounds in 3 patients, a variety of other penetrating injuries in 10 patients, and in 5 patients the injuries resulted from blunt trauma. Treatment of the rectal injury was determined by the bias of the operating surgeon, the condition of the patient, and the magnitude of the rectal injury. Proximal loop colostomies were performed in 44 patients, diverting colostomies in 51 patients, Hartmann's procedure in 4 patients, and an abdominoperineal resection in 1 patient. Extraperitoneal rectal perforations were closed in 21 patients and the rectum was irrigated free of feces in 46 patients. Transperineal, presacral drainage was used in 93 patients. Infectious complications potentially related to the management of the rectal wound occurred in 11 patients (11%) and included abdominal or pelvic abscesses (4 patients), wound infections (6 patients), rectocutaneous fistulas (3 patients), and missile tract infections (2 patients). Four patients (4%) died as a result of their injuries. Of the therapeutic options available, statistical analysis revealed that only the failure to drain the presacral space increased the likelihood of infectious complications (p = 0.03); however, as it could not be determined with certainty that the use of, or failure to use, any particular therapeutic option had an effect on the risk of death. It is concluded that colostomy and drainage are the foundations of the successful treatment of civilian injuries to the extraperitoneal rectum. The use of adjuncts such as diverting colostomies, repair of the rectal wound, and irrigation of the rectum has little effect on mortality and morbidity. PMID:2705824

Erythropoietin interacts with vascular endothelial growth factor (VEGF) and stimulates endothelial cell mitosis and motility; thus it may be of importance in the complex phenomenon of wound healing. The purpose of this study was to investigate the effect of recombinant human erythropoietin (rHuEPO) on experimental burn wounds. Randomized experiment. Research laboratory. C57BL/6 male mice weighing 25-30 g. Mice were immersed in 80 degrees C water for 10 secs to achieve a deep-dermal second degree burn. Animals were randomized to receive either rHuEPO (400 units/kg/day for 14 days in 100 microL subcutaneously) or its vehicle alone (100 microl/day distilled water for 14 days subcutaneously). On day 14 the animals were killed. Burn areas were used for histologic examination, evaluation of neoangiogenesis by immunohistochemistry, and expression (Western blot) of the specific endothelial marker CD31 as well as quantification of microvessel density, measurement of VEGF wound content (enzyme-linked immunosorbent assay), expression (Western blot) of endothelial and inducible nitric oxide synthases, and determination of wound nitric oxide (NO) products. rHuEPO increased burn wound reepithelialization and reduced the time to final wound closure. These effects were completely abated by a passive immunization with specific antibodies against erythropoietin. rHuEPO improved healing of burn wound through increased epithelial proliferation, maturation of the extracellular matrix, and angiogenesis. The hematopoietic factor augmented neoangiogenesis as suggested by the marked increase in microvessel density and by the robust expression of the specific endothelial marker CD31. Furthermore, rHuEPO enhanced the wound content of VEGF caused a marked expression of endothelial and inducible nitric oxide synthases and increased wound content of nitric oxide products. Our study suggests that rHuEPO may be an effective therapeutic approach to improve clinical outcomes after thermal injury.

To determine the accuracy of complaints of abdominal pain and findings of abdominal tenderness for identifying children with intra-abdominal injury (IAI) stratified by Glasgow Coma Scale (GCS) score. This was a prospective, multicenter observational study of children with blunt torso trauma and a GCS score ≥13. We calculated the sensitivity of abdominal findings for IAI with 95% CI stratified by GCS score. We examined the association of isolated abdominal pain or tenderness with IAI and that undergoing acute intervention (therapeutic laparotomy, angiographic embolization, blood transfusion, or ≥2 nights of intravenous fluid therapy). Among the 12 044 patients evaluated, 11 277 (94%) had a GCS score of ≥13 and were included in this analysis. Sensitivity of abdominal pain for IAI was 79% (95% CI, 76%-83%) for patients with a GCS score of 15, 51% (95% CI, 37%-65%) for patients with a GCS score of 14, and 32% (95% CI, 14%-55%) for patients with a GCS score of 13. Sensitivity of abdominal tenderness for IAI also decreased with decreasing GCS score: 79% (95% CI, 75%-82%) for a GCS score of 15, 57% (95% CI, 42%-70%) for a GCS score of 14, and 37% (95% CI, 19%-58%) for a GCS score of 13. Among patients with isolated abdominal pain and/or tenderness, the rate of IAI was 8% (95% CI, 6%-9%) and the rate of IAI undergoing acute intervention was 1% (95% CI, 1%-2%). The sensitivity of abdominal findings for IAI decreases as GCS score decreases. Although abdominal computed tomography is not mandatory, the risk of IAI is sufficiently high that diagnostic evaluation is warranted in children with isolated abdominal pain or tenderness.

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.

Polymeric hydrogels for burn wound care: Advanced skin wound dressings and regenerative templates.

Wound closure represents a primary goal in the treatment of very deep and/or large wounds, for which the mortality rate is particularly high. However, the spontaneous healing of adult skin eventually results in the formation of epithelialized scar and scar contracture (repair), which might distort the tissues and cause lifelong deformities and disabilities. This clinical evidence suggests that wound closure attained by means of skin regeneration, instead of repair, should be the true goal of burn wound management. The traditional concept of temporary wound dressings, able to stimulate skin healing by repair, is thus being increasingly replaced by the idea of temporary scaffolds, or regenerative templates, able to promote healing by regeneration. As wound dressings, polymeric hydrogels provide an ideal moisture environment for healing while protecting the wound, with the additional advantage of being comfortable to the patient, due to their cooling effect and non-adhesiveness to the wound tissue. More importantly, recent advances in regenerative medicine demonstrate that bioactive hydrogels can be properly designed to induce at least partial skin regeneration in vivo. The aim of this review is to provide a concise insight on the key properties of hydrogels for skin healing and regeneration, particularly highlighting the emerging role of hydrogels as next generation skin substitutes for the treatment of full-thickness burns.

To form a wound information management scheme with objectivity, standardization, and convenience by means of wound information management system. A wound information management system was set up with the acquisition terminal, the defined wound description, the data bank, and related softwares. The efficacy of this system was evaluated in clinical practice. The acquisition terminal was composed of the third generation mobile phone and the software. It was feasible to get access to the wound information, including description, image, and therapeutic plan from the data bank by mobile phone. During 4 months, a collection of a total of 232 wound treatment information was entered, and accordingly standardized data of 38 patients were formed automatically. This system can provide standardized wound information management by standardized techniques of acquisition, transmission, and storage of wound information. It can be used widely in hospitals, especially primary medical institutions. Data resource of the system makes it possible for epidemiological study with large sample size in future.

A filament wound spherical structure is described comprising a plurality of filament band sets disposed about the surface of a mandrel with each band of each set formed of a continuous filament circumferentially wound about the mandrel a selected number of circuits and with each circuit of filament being wound parallel to and contiguous with an immediate previously wound circuit. 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

Trace metal analysis by laser ablation-inductively coupled plasmamass spectrometry and x-ray K-edge densitometry of forensic samples

Energy Technology Data Exchange (ETDEWEB)

Berry, Jonna Elizabeth [Iowa State Univ., Ames, IA (United States)

This dissertation describes a variety of studies on the determination of trace elements in samples with forensic importance. Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) was used to determine the trace element composition of numerous lipstick samples. Lipstick samples were determined to be homogeneous. Most lipstick samples of similar colors were readily distinguishable at a 95% confidence interval based on trace element composition. Numerous strands of a multi-strand speaker cable were analyzed by LA-ICP-MS. The strands in this study are spatially heterogeneous in trace element composition. In actual forensic applications, the possibility of spatial heterogeneity must be considered, especially in cases where only small samples (e.g., copper wire fragments after an explosion) are available. The effects of many unpredictable variables, such as weather, temperature, and human activity, on the retention of gunshot residue (GSR) around projectile wounds were assessed with LAICP- MS. Skin samples around gunshot and stab wounds and larvae feeding in and around the wounds on decomposing pig carcasses were analyzed for elements consistent with GSR (Sb, Pb, Ba, and Cu). These elements were detected at higher levels in skin and larvae samples around the gunshot wounds compared to the stab wounds for an extended period of time throughout decomposition in both a winter and summer study. After decomposition, radiographic images of the pig bones containing possible damage from bullets revealed metallic particles embedded within a number of bones. Metallic particles within the bones were analyzed with x-ray, K-edge densitometry and determined to contain lead, indicating that bullet residue can be retained throughout decomposition and detected within bones containing projectile trauma.

Don't Forget the Abdominal Wall: Imaging Spectrum of Abdominal Wall Injuries after Nonpenetrating Trauma.

Abdominal wall injuries occur in nearly one of 10 patients coming to the emergency department after nonpenetrating trauma. Injuries range from minor, such as abdominal wall contusion, to severe, such as abdominal wall rupture with evisceration of abdominal contents. Examples of specific injuries that can be detected at cross-sectional imaging include abdominal muscle strain, tear, or hematoma, including rectus sheath hematoma (RSH); traumatic abdominal wall hernia (TAWH); and Morel-Lavallée lesion (MLL) (closed degloving injury). These injuries are often overlooked clinically because of (a) a lack of findings at physical examination or (b) distraction by more-severe associated injuries. However, these injuries are important to detect because they are highly associated with potentially grave visceral and vascular injuries, such as aortic injury, and because their detection can lead to the diagnosis of these more clinically important grave traumatic injuries. Failure to make a timely diagnosis can result in delayed complications, such as bowel hernia with potential for obstruction or strangulation, or misdiagnosis of an abdominal wall neoplasm. Groin injuries, such as athletic pubalgia, and inferior costochondral injuries should also be considered in patients with abdominal pain after nonpenetrating trauma, because these conditions may manifest with referred abdominal pain and are often included within the field of view at cross-sectional abdominal imaging. Radiologists must recognize and report acute abdominal wall injuries and their associated intra-abdominal pathologic conditions to allow appropriate and timely treatment. © RSNA, 2017.

Correlation between intra-abdominal pressure and pulmonary volumes after superior and inferior abdominal surgery

Full Text Available OBJECTIVE:Patients undergoing abdominal surgery are at risk for pulmonary complications. The principal cause of postoperative pulmonary complications is a significant reduction in pulmonary volumes (FEV1 and FVC to approximately 65-70% of the predicted value. Another frequent occurrence after abdominal surgery is increased intra-abdominal pressure. The aim of this study was to correlate changes in pulmonary volumes with the values of intra-abdominal pressure after abdominal surgery, according to the surgical incision in the abdomen (superior or inferior.METHODS:We prospectively evaluated 60 patients who underwent elective open abdominal surgery with a surgical time greater than 240 minutes. Patients were evaluated before surgery and on the 3rd postoperative day. Spirometry was assessed by maximal respiratory maneuvers and flow-volume curves. Intra-abdominal pressure was measured in the postoperative period using the bladder technique.RESULTS:The mean age of the patients was 56±13 years, and 41.6% 25 were female; 50 patients (83.3% had malignant disease. The patients were divided into two groups according to the surgical incision (superior or inferior. The lung volumes in the preoperative period showed no abnormalities. After surgery, there was a significant reduction in both FEV1 (1.6±0.6 L and FVC (2.0±0.7 L with maintenance of FEV1/FVC of 0.8±0.2 in both groups. The maximum intra-abdominal pressure values were similar (p= 0.59 for the two groups. There was no association between pulmonary volumes and intra-abdominal pressure measured in any of the groups analyzed.CONCLUSIONS:Our results show that superior and inferior abdominal surgery determines hypoventilation, unrelated to increased intra-abdominal pressure. Patients at high risk of pulmonary complications should receive respiratory care even if undergoing inferior abdominal surgery.

The maximum intra-abdominal pressure values were similar (p=0.59) for the two groups. There was no association between pulmonary volumes and intra-abdominal pressure measured in any of the groups analyzed. Our results show that superior and inferior abdominal surgery determines hypoventilation, unrelated to increased intra-abdominal pressure. Patients at high risk of pulmonary complications should receive respiratory care even if undergoing inferior abdominal surgery.

Advertisements targeted at the elderly population suggest that antioxidant therapy will reduce free radicals and promote wound healing, yet few scientific studies substantiate these claims. To better understand the potential utility of supplemental antioxidant therapy for wound healing, we tested the hypothesis that age and tissue ischemia alter the balance of endogenous antioxidant enzymes. Using a bipedicled skin flap model, ischemic and non-ischemic wounds were created on young and aged rats. Wound closure and the balance of the critical antioxidants superoxide dismutase and glutathione in the wound bed were determined. Ischemia delayed wound closure significantly more in aged rats. Lower superoxide dismutase 2 and glutathione in non-ischemic wounds of aged rats indicate a basal deficit due to age alone. Ischemic wounds from aged rats had lower superoxide dismutase 2 protein and activity initially, coupled with decreased ratios of reduced/oxidized glutathione and lower glutathione peroxidase activity. De novo glutathione synthesis, to restore redox balance in aged ischemic wounds, was initiated as evidenced by increased glutamate cysteine ligase. Results demonstrate deficiencies in two antioxidant pathways in aged rats that become exaggerated in ischemic tissue, culminating in profoundly impaired wound healing and prolonged inflammation.

Lonicera japonica Thunb. (Caprifoliaceae), a widely used traditional Chinese medicinal plant, is used to treat some infectious diseases and it may have uses as a healthy food and applications in cosmetics and as an ornamental groundcover. The ethanol extract of the flowering aerial parts of L. japonica (LJEE) was investigated for its healing efficiency in a rat excision wound model. Excision wounds were inflicted upon three groups of eight rats each. Healing was assessed by the rate of wound contraction in skin wound sites in rats treated with simple ointment base, 10% (w/w) LJEE ointment, or the reference standard drug, 0.2% (w/w) nitrofurazone ointment. The effects of LJEE on the contents of hydroxyproline and hexosamine during healing were estimated. The antimicrobial activity of LJEE against microorganisms was also assessed. The in vivo anti-inflammatory activity of LJEE was investigated to understand the mechanism of wound healing. LJEE exhibited significant antimicrobial activity against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Candida albicans, and Candida tropicalis. The ointment formulation prepared with 10% (w/w) LJEE exhibited potent wound healing capacity as evidenced by the wound contraction in the excision wound model. The contents of hydroxyproline and hexosamine also correlated with the observed healing pattern. These findings were supported by the histopathological characteristics of healed wound sections, as greater tissue regeneration, more fibroblasts, and angiogenesis were observed in the 10% (w/w) LJEE ointment-treated group. The results also indicated that LJEE possesses potent anti-inflammatory activity, as it enhanced the production of anti-inflammatory cytokines that suppress proinflammatory cytokine production. The results suggest that the antimicrobial and anti-inflammatory activities of LJEE act synergistically to accelerate wound repair.

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.

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'.

Develop green wound dressings which exhibit enhanced wound-healing ability and potent antibacterial effects. Honey, polyvinyl alcohol, chitosan nanofibers were electrospun and loaded with bee venom, propolis and/or bacteriophage against the multidrug-resistant Pseudomonas aeruginosa and examined for their antibacterial, wound-healing ability and cytotoxicity. Among different formulations of nanofibers, honey, polyvinyl alcohol, chitosan-bee venom/bacteriophage exhibited the most potent antibacterial activity against all tested bacterial strains (Gram-positive and -negative strains) and achieved nearly complete killing of multidrug-resistant P. aeruginosa. In vivo testing revealed enhanced wound-healing results and cytotoxicity testing proved improved biocompatibility. The developed biocompatible nanofibers represent competitive wound-healing dressings with potent antibacterial and wound-healing activity.

AIM: The technical performance of abdominal ultrasound in the investigation of acute abdominal pain has been thoroughly investigated but its therapeutic effects are less well understood. We aimed to determine the therapeutic effect of abdominal ultrasound in the investigation of acute abdominal pain. MATERIAL AND METHODS: A pre- and post-intervention observational study design was used to determine the diagnostic and therapeutic effects of abdominal ultrasound for acute abdominal pain. Referring clinicians completed a pre-ultrasound questionnaire that detailed their leading diagnosis, confidence in this and intended management in 100 consecutive adult patients. Following ultrasound a second questionnaire was completed. This again detailed the leading diagnosis, confidence in this and their intended management. Clinicians quantified the management contribution of ultrasound both for the individual case in question and in their clinical experience generally. RESULTS: The leading diagnosis was either confirmed or rejected in 72 patients and a new diagnosis provided where no prior differential diagnosis existed in 10. Diagnostic confidence increased significantly following ultrasound (mean score 6·5 pre-ultrasound vs 7·6 post-ultrasound, P < 0·001). Intended management changed following ultrasound in 22 patients; 15 intended laparotomies were halted and a further seven patients underwent surgery where this was not originally intended. Ultrasound was rated either 'very' or 'moderately' helpful in 87% of patients, with 99% of clinicians finding it either 'very' or 'moderately' helpful generally. CONCLUSION: Abdominal ultrasound has considerable diagnostic and therapeutic effect in the setting of acute abdominal pain. Dhillon, S. et al. (2002)

The management of perineal wounds

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.

2007-03-01

Randomised clinical trials (RCTs) to evaluate diabetic foot wound therapies have systematically eliminated large acute wounds from evaluation, focusing only on smaller chronic wounds. The purpose of this study was to evaluate the proportion and rate of wound healing in acute and chronic wounds after partial foot amputation in individuals with diabetes treated with negative pressure wound therapy (NPWT) delivered by the vacuum-assisted closure (VAC) device or with standard wound therapy (SWT). This study constitutes a secondary analysis of patients enrolled in a 16-week RCT of NPWT: 162 open foot amputation wounds (mean wound size = 20.7 cm(2)) were included. Acute wounds were defined as the wounds less than 30 days after amputation, whereas chronic wounds as the wounds greater than 30 days. Inclusion criteria consisted of individuals older than 18 years, presence of a diabetic foot amputation wound up to the transmetatarsal level and adequate perfusion. Wound size and healing were confirmed by independent, blinded wound evaluators. Analyses were done on an intent-to-treat basis. There was a significantly higher proportion of acute wounds (SWT = 59; NPWT = 63) than chronic wounds (SWT = 26; NPWT = 14), evaluated in this clinical trial (P = 0.001). There was no significant difference in the proportion of acute and chronic wounds achieving complete wound closure in either treatment group. Despite this finding, the Kaplan-Meier curves demonstrated statistically significantly faster healing in the NPWT group in both acute (P = 0.030) and chronic wounds (P = 0.033). Among the patients treated with NPWT via the VAC, there was not a significant difference in healing as a function of chronicity. In both the acute and the chronic wound groups, results for patients treated with NPWT were superior to those for the patients treated with SWT. These results appear to indicate that wound duration should not deter the clinician from using this modality to treat complex wounds.

Atypical stab injury suggesting ritual suicide

Full Text Available Sharp weapons have been one of the most common deadly tools in cases of homicide and suicide for a long time. Tentative incisions accompany the majority of suicides by sharp force and the absence of hesitation marks provokes questions about the manner of death. We present the bizarre fatality of a 41-year-old male with an isolated circumscribed incision on the right neck, where the body was found lying in a pool of blood in the shower of his apartment. The internal examination revealed a 4-cm-long channel-like defect running inwardly and downwardly along the right sternocleidomastoid region. The cause of death was external bleeding from an injured right carotid artery and internal jugular vein. The wound had clean non-contused margins without any conspicuous hesitation injuries. A fragment of a razor blade, found in blood splatters, was identified as the only potential injuring tool. The case was classified as a suicide.

Exploring the concept of a team approach to wound care: Managing wounds as a team.

Moore, Zena; Butcher, Gillian; Corbett, Lisa Q; McGuiness, William; Snyder, Robert J; van Acker, Kristien

2014-05-01

Background - The growing prevalence and incidence of nonhealing acute and chronic wounds is a worrying concern. A major challenge is the lack of united services aimed at addressing the complex needs of individuals with wounds. However, the WHO argues that interprofessional collaboration in education and practice is key to providing the best patient care, enhancing clinical and health-related outcomes and strengthening the health system. It is based on this background that the team approach to wound care project was conceptualised. The project was jointly initiated and realised by the Association for the Advancement of Wound Care (AAWC-USA), the Australian Wound Management Association (AWMA) and the European Wound Management Association (EWMA). Aim - The aim of this project was to develop a universal model for the adoption of a team approach to wound care. Objective The overarching objective of this project was to provide recommendations for implementing a team approach to wound care within all clinical settings and through this to develop a model for advocating the team approach toward decision makers in national government levels. Method An integrative literature review was conducted. Using this knowledge, the authors arrived at a consensus on the most appropriate model to adopt and realise a team approach to wound care. Results - Eighty four articles met the inclusion criteria. Following data extraction, it was evident that none of the articles provided a definition for the terms multidisciplinary, interdisciplinary or transdisciplinary in the context of wound care. Given this lack of clarity within the wound care literature, the authors have here developed a Universal Model for the Team Approach to Wound Care to fill this gap in our current understanding. Conclusion - We advocate that the patient should be at the heart of all decision-making, as working with the Universal Model for the Team Approach to Wound Care begins with the needs of the patient.

Full Text Available ABSTRACT OBJECTIVE: To evaluate the results and benefits obtained from the topical use of negative pressure wound therapy (NPWT in patients with infected wounds. METHODS: This was a retrospective study of 20 patients (17 males and three females, mean age 42 years with infected wounds treated using NPWT. The infected wounds were caused by trauma. The treatment system used was VAC.(r (Vacuum Assisted Closure, KCI, San Antonio, United States applied to the wound in continuous mode from 100 to 125 mmHg. The parameters related to the wounds (location, number of VAC changes, the size of the defects in the soft parts, and the evolution of the state of the wound, length of hospital stay, length of intravenous antibiotic therapy, and complications related to the use of this therapy were evaluated. RESULTS: The mean length of the hospital stay, use of NPWT, and antibacterial therapy were 41 days, 22.5 days, and 20 days respectively. The use of the VAC led to a mean reduction of 29% in the wound area (95.65-68.1 cm2; p < 0.05. Only one patient did not show any improvement in the final appearance of the wound with complete eradication of the infection. No complication directly caused by NPWT was observed. CONCLUSION: NPWT stimulates infection-free scar tissue formation in a short time, and is a quick and comfortable alternative to conventional infected wounds treatment methods.

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

Chronic abdominal wall pain is a poorly recognized clinical problem despite being an important element in the differential diagnosis of abdominal pain. This review is based on pertinent articles that were retrieved by a selective search in PubMed and EMBASE employing the terms "abdominal wall pain" and "cutaneous nerve entrapment syndrome," as well as on the authors' clinical experience. In 2% to 3% of patients with chronic abdominal pain, the pain arises from the abdominal wall; in patients with previously diagnosed chronic abdominal pain who have no demonstrable pathological abnormality, this likelihood can rise as high as 30% . There have only been a small number of clinical trials of treatment for this condition. The diagnosis is made on clinical grounds, with the aid of Carnett's test. The characteristic clinical feature is strictly localized pain in the anterior abdominal wall, which is often mischaracterized as a "functional" complaint. In one study, injection of local anesthesia combined with steroids into the painful area was found to relieve pain for 4 weeks in 95% of patients. The injection of lidocaine alone brought about improvement in 83-91% of patients. Long-term pain relief ensued after a single lidocaine injection in 20-30% of patients, after repeated injections in 40-50% , and after combined lidocaine and steroid injections in up to 80% . Pain that persists despite these treatments can be treated with surgery (neurectomy). Chronic abdominal wall pain is easily diagnosed on physical examination and can often be rapidly treated. Any physician treating patients with abdominal pain should be aware of this condition. Further comparative treatment trials will be needed before a validated treatment algorithm can be established.

Full Text Available BackgroundRosa damascena, a type of herb, has been used for wound healing in Eastern folk medicine. The goal of this study was to evaluate the effectiveness of rose placenta from R. damascena in a full-thickness wound model in mice.MethodsSixty six-week-old C57BL/6N mice were used. Full-thickness wounds were made with an 8-mm diameter punch. Two wounds were made on each side of the back, and wounds were assigned randomly to the control and experimental groups. Rose placenta (250 µg was injected in the experimental group, and normal saline was injected in the control group. Wound sizes were measured with digital photography, and specimens were harvested. Immunohistochemical staining was performed to assess the expression of epidermal growth factor (EGF, vascular endothelial growth factor (VEGF, transforming growth factor-β1 (TGF-β1, and CD31. Vessel density was measured. Quantitative analysis using an enzyme-linked immunosorbent assay (ELISA for EGF was performed. All evaluations were performed on postoperative days 0, 2, 4, 7, and 10. Statistical analyses were performed using the paired t-test.Results On days 4, 7, and 10, the wounds treated with rose placenta were significantly smaller. On day 2, VEGF and EGF expression increased in the experimental group. On days 7 and 10, TGF-β1 expression decreased in the experimental group. On day 10, vessel density increased in the experimental group. The increase in EGF on day 2 was confirmed with ELISA.ConclusionsRose placenta was found to be associated with improved wound healing in a mouse full-thickness wound model via increased EGF release. Rose placenta may potentially be a novel drug candidate for enhancing wound healing.

Torsion of abdominal appendages presenting with acute abdominal pain

Al-Jaberi, Tareq M.; Gharabeih, Kamal I.; Yaghan, Rami J.

2000-01-01

Diseases of abnormal appendages are rare causes of abdominal pain in all age groups. Nine patients with torsion and infraction of abdominal appendages were retrospectively reviewed. Four patients had torsion and infarction of the appendices epiploicae, four patients had torsion and infarction of the falciform ligament. The patient with falciform ligament disease represents the first reported case of primary torsion and infarction of the falciform ligament, and the patient with the transverse colon epiplocia represents the first reported case of vibration-induced appendix epiplocia torsion and infarction. The patient with the falciform ligament disease presented with a tender upper abdominal mass and the remaining patients were operated upon with the preoperative diagnosis of acute appendicitis. The presence of normal appendix with free serosanguinous fluid in the peritoneal cavity should raise the possibility of a disease and calls for further evaluation of the intra-abdominal organs. If the diagnosis is suspected preoperatively, CT scan and ultrasound may lead to a correct diagnosis and possibly conservative management. Laparoscopy is playing an increasing diagnostic and therapeutic role in such situations. (author)

In the treatment and monitoring of a diabetic or chronic wound, accurate and repeatable measurement of the wound provides indispensable data for the patient's medical record. This study aims to measure the accuracy of the laser-assisted wound measurement (LAWM) device against traditional methods in the measurement of area, depth and volume. We measured four 'healing' wounds in a Play-Doh(®) -based model over five subsequent states of wound healing progression in which the model was irregularly filled in to replicate the healing process. We evaluated the LAWM device against traditional methods including digital photograph assessment with National Institutes of Health ImageJ software, measurements of depth with a ruler and weight-to-volume assessment with dental paste. Statistical analyses included analysis of variance (ANOVA) and paired t-tests. We demonstrate that there are significantly different and nearly statistically significant differences between traditional ruler depth measurement and LAWM device measurement, but there are no statistically significant differences in area measurement. Volume measurements were found to be significantly different in two of the wounds. Rate of percentage change was analysed for volume and depth in the wound healing model, and the LAWM device was not significantly different than the traditional measurement technique. While occasionally inaccurate in its absolute measurement, the LAWM device is a useful tool in the clinician's arsenal as it reliably measures rate of percentage change in depth and volume and offers a potentially aseptic alternative to traditional measurement techniques. © 2014 The Authors.

Background Prolonged healing and persistent inflammation following surgery for rhinosinusitis impacts patient satisfaction and healthcare resources. Cytokines interleukin (IL)-4, 5, and 13 are important mediators in Th2 inflammatory rhinosinusitis. Decreased wound healing has been demonstrated with Th2 cytokine exposure, but this has not been extensively studied in sinonasal epithelium. We hypothesized that in vitro exposure of primary sinonasal epithelial cell cultures to Th2 inflammatory cytokine IL-4 and IL-13 would impair wound resealing and decrease expression of annexin A2 at the wound edge. Methods Following 24-hour exposure to IL-4, 5, or 13 versus controls, sterile linear mechanical wounds were created in primary sinonasal epithelial cultures (n = 12 wounds per condition). Wounds were followed for 36 hours or until complete closure and residual wound areas were calculated by image analysis. Group differences in annexin A2 were assessed by immunofluorescence labeling, confocal microscopy, and Western blots. Results Significant wound closure differences were identified across cytokine exposure groups (pprotein levels were decreased in IL-4 treated wounds when compared to control wounds (p<0.01). Conclusions Th2 cytokine IL-4 decreases sinonasal epithelial wound closure in vitro. Annexin A2 is also diminished with IL-4 exposure. This supports the hypothesis that IL-4 exposure impairs sinonasal epithelial wound healing and may contribute to prolonged healing in Th2 inflammatory rhinosinusitis. PMID:23468432

Wound management represents a major clinical challenge on what concerns healing enhancement and pain control. The selection of an appropriate dressing plays an important role in both recovery and esthetic appearance of the regenerated tissue. Despite the wide range of available dressings, the progress in the wound care market relies on the increasing interest in using natural-based biomedical products. Herein, a rat wound-dressing model of partial-thickness skin wounds was used to study newly developed chitosan/soy (cht/soy)-based membranes as wound-dressing materials. Healing and repair of nondressed, cht/soy membrane-dressed, and Epigard(®)-dressed wounds were followed macroscopically and histologically for 1 and 2 weeks. cht/soy membranes performed better than the controls, promoting a faster wound repair. Re-epithelialization, observed 1 week after wounding, was followed by cornification of the outermost epidermal layer at the second week of dressing, indicating repair of the wounded tissue. The use of this rodent model, although in impaired healing conditions, may enclose some drawbacks regarding the inevitable wound contraction. Moreover, being the main purpose the evaluation of cht/soy-based membranes' performance in the absence of growth factors, the choice of a clinically relevant positive control was limited to a polymeric mesh, without any growth factor influencing skin healing/repair, Epigard. These new cht/soy membranes possess the desired features regarding healing/repair stimulation, ease of handling, and final esthetic appearance-thus, valuable properties for wound dressings.

Intra-abdominal pressure and abdominal compartment syndrome in acute general surgery.

LENUS (Irish Health Repository)

Sugrue, Michael

2012-01-31

BACKGROUND: Intra-abdominal pressure (IAP) is a harbinger of intra-abdominal mischief, and its measurement is cheap, simple to perform, and reproducible. Intra-abdominal hypertension (IAH), especially grades 3 and 4 (IAP > 18 mmHg), occurs in over a third of patients and is associated with an increase in intra-abdominal sepsis, bleeding, renal failure, and death. PATIENTS AND METHODS: Increased IAP reading may provide an objective bedside stimulus for surgeons to expedite diagnostic and therapeutic work-up of critically ill patients. One of the greatest challenges surgeons and intensivists face worldwide is lack of recognition of the known association between IAH, ACS, and intra-abdominal sepsis. This lack of awareness of IAH and its progression to ACS may delay timely intervention and contribute to excessive patient resuscitation. CONCLUSIONS: All patients entering the intensive care unit (ICU) after emergency general surgery or massive fluid resuscitation should have an IAP measurement performed every 6 h. Each ICU should have guidelines relating to techniques of IAP measurement and an algorithm for management of IAH.

Aloe vera and Vitis vinifera have been traditionally used as wound healing agents. The present study aimed to investigate the effects of aloe emodin and resveratrol in the burn wound healing procedure. Burn wounds are common in developed and developing countries, however, in developing countries, the incidence of severe complications is higher and financial resources are limited. The results of the present study demonstrated that neither aloe emodin or resveratrol were cytotoxic to THP-1 macrophages at concentrations of 1, 100 and 500 ng/ml. A significant increase in wound-healing activity was observed in mice treated with the aloe emodin and resveratrol, compared with those which received control treatments. The levels of IL-1β in the exudates of the burn wound area of the treated mice increased in a time-dependent manner over 7 days following burn wound injury. At 10 days post-injury, steady and progressive wound healing was observed in the control animals. The present study confirmed that increased wound healing occurs following treatment with aloe emodin,, compared with resveratrol, providing support for the use of Aloe vera plants to improve burn wound healing.

Negative Pressure Wound Therapy in Maxillofacial Applications

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.

Scalp defects and lacerations present a reconstructive challenge to plastic surgeons. Many methods have been described from the use of skin grafting to rotation flaps. Here we present a method of closure of a contaminated scalp wound with the use of Kirschner wires. In our case, closure of scalp laceration was made possible with the use of 1.4 Kirschner wires and cable tie/ zip tie fasteners. The duration to closure of wound was 10 days. In reconstructing the scalp defect, this method was found to adhere to principles of scalp reconstruction. There were no post operative complications found from the procedure. On initial application on the edge of the wound, tension applied caused the K wires to cut through the wound edge. On replacement of K wires 1cm away from wound edge the procedure was not plagued by any further complication. In conclusion we find scalp closure with Kirschner wires are a simple and effective method for scalp wound closure.

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.

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.

Enzymatic wound debridement; role of papaya in the management of post cesarean gaped wounds

Background: Enzymatic wound debridement is an emerging concept in facilitating the wound healing process. Papaya has de-sloughing, antibacterial and wound healing properties. It has been used in African countries since centuries for different medicinal pur-poses. Apart from anecdotal reports and few studies on chronic ulcers and burns, no planned studies are available to support its action in postoperative wound infection.Objectives: To compare efficacy and safety of papaya dressing with conventional wound dressing with povidone iodine in post cesarean section gaped wounds. Setting: Gynecology Unit 3, Sir Ganga Ram Hospital Lahore - Pakistan, over a period of six months(June 2012 to Nov 2012). Study Design: Randomized, quasi experimental stu-dy. Materials and Methods: The study sample included 60 patients with post cesarean section gaped wounds. The sample was divided into two groups; thirty patients as Group A or the study group received Papaya dressing and rest of thirty patients as Group B or the control group received Povidone iodine dressing. Wounds were thoroughly washed with saline and then mashed unripe papaya was spread over the whole area of wound in the study group and povidone iodine in the control group. Wounds were covered with sterile bandage for at least 48 hours in study group and 24 hours in the control group. The process was repeated till a clean base of wound with healthy granulation tis-sue was achieved suitable for secondary suture. The efficacy parameters studied were the duration of time needed to develop healthy granulation tissue and total duration of hospital stay which were compared bet-ween the two groups. Safety factors studied were the adverse effects of medications used in the study. Results: Out of 1200 cesarean sections done during study period, sixty (5%) were gaped in the post-operative period. Out of 60, 55 (90%) were emergency and only 5 (10%) were elective cesarean sections. All the sixty patients with postoperative gaped

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.

The Use of Tensor Fascia Lata Pedicled Flap in Reconstructing Full Thickness Abdominal Wall Defects and Groin Defects Following Tumor Ablation

Rifaat, M.A.; Abdel Gawad, W.S.

2005-01-01

The tensor fascia lata is a versatile flap with many uses in reconstructive plastic surgery. As a pedicled flap its reach to the lower abdomen and groin made it an attractive option for reconstructing soft tissue defects after tumor ablation. However, debate exists on the safe dimension of the flap, as distal tip necrosis is common. Also, the adequacy of the fascia lata as a sole substitute for abdominal wall muscles has been disputable. The aim of the current study is to report our experience and clinical observations with this flap in reconstructing those challenging defects and to discuss the possible options to minimize the latter disputable issues. Patients and Methods: From April 2001 to April 2004, 12 pedicled TFL flaps were used to reconstruct 5 central abdominal wall full thickness defects and 6 groin soft tissue defects following tumor resection. ]n one case, bilateral flaps were used to reconstruct a large central abdominal wall defect. There were 4 males and 7 females. Their age ranged from 19 to 60. From the abdominal wall defects group, all repairs were enforced primarily with a prolene mesh except for one patient who was the first in this study. Patients presenting with groin defects required coverage of exposed vessels following tumor resection. All patients in the current study underwent immediate reconstruction. The resulting soft tissue defects in this study were due to resection of 4 abdominal wall desmoid tumors, a colonic carcinoma infiltrating the abdominal wall, 4 primary groin soft developed in a flap used to cover a groin defect. In the former 3 cases, The flap was simply transposed without complete islanding of the flap. In the latter case, a very large flap was harvested beyond the safe limits with its distal edge just above the knee. In addition, wound dehiscence of the flap occurred in 2 other cases from the groin group. Nevertheless, all the wounds healed spontaneously with repeated dressings. Out of the 5 cases that underwent

Objective: Nanofibers for tissue scaffolding and wound dressings hold great potential in realizing enhanced healing of wounds in comparison with conventional counterparts. Previously, we demonstrated good fibroblast adherence and growth on a newly developed scaffold, Tegaderm™-Nanofiber (TG-NF), made from poly ɛ-caprolactone (PCL)/gelatin nanofibers electrospun onto Tegaderm (TG). The purpose of this study is to evaluate the performance and safety of TG-NF dressings in partial-thickness wound in a pig healing model. Approach: To evaluate the rate of reepithelialization, control TG, human dermal fibroblast-seeded TG-NF(+) and -unseeded TG-NF(-) were randomly dressed onto 80 partial-thickness burns created on four female and four male pigs. Wound inspections and dressings were done after burns on day 7, 14, 21, and 28. On day 28, full-thickness biopsies were taken for histopathological evaluation by Masson-Trichrome staining for collagen and hematoxylin-eosin staining for cell counting. Results: No infection and severe inflammation were recorded. Wounds treated with TG-NF(+) reepithelialized significantly faster than TG-NF(-) and control. Wound site inflammatory responses to study groups were similar as total cell counts on granulation tissues show no significant differences. Most of the wounds completely reepithelialized by day 28, except for two wounds in control and TG-NF(-). A higher collagen coverage was also recorded in the granulation tissues treated with TG-NF(+). Innovation and Conclusion: With better reepithelialization achieved by TG-NF(+) and similar rates of wound closure by TG-NF(-) and control, and the absence of elevated inflammatory responses to TG-NF constructs, TG-NF constructs are safe and demonstrated good healing potentials that are comparable to Tegaderm.

Abdominal radiography and ultrasonography are commonly used as part of the initial diagnostic plan for cats with nonspecific signs of abdominal disease. This retrospective study compared the clinical usefulness of abdominal radiography and ultrasonography in 105 feline patients with signs of abdominal disease. The final diagnosis was determined more commonly with ultrasonography (59%) compared to radiography (25.7%). Ultrasonography was also able to provide additional clinically relevant information in 76% of cases, and changed or refined the diagnosis in 47% of cases. Based on these findings, ultrasonography may be sufficient as an initial diagnostic test for the investigation of feline abdominal disease. PMID:26483582

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.

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.

[Differential diagnosis of abdominal pain].

Science.gov (United States)

Frei, Pascal

2015-09-02

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

Antibiofilm Efficacy of DispersinB Wound Spray Used in Combination with a Silver Wound Dressing

2014-01-01

Full Text Available Chronic wounds including diabetic foot ulcers, pressure ulcers, and venous leg ulcers are a worldwide health problem. As the traditional methods of treatment have proven ineffective against chronic wounds involving biofilms, there is an unmet clinical need for developing products with an antibiofilm component that inhibits and/or disrupts biofilms and thus make the biofilm-embedded bacteria more susceptible to antimicrobial therapy. We developed a DispersinB® antibiofilm enzyme-based wound spray for treating chronic wounds in conjunction with an antimicrobial. Under in vitro conditions, the DispersinB® and Acticoat™ combination performed significantly better ( P < 0.05 than Acticoat™ alone, indicating the synergy between the two compounds because of DispersinB® enhancing the antimicrobial activity of Acticoat™. Furthermore, DispersinB® wound spray enhanced the antimicrobial activity of Acticoat™ in a chronic wound mouse model of methicillin-resistant Staphylococcus aureus (MRSA infection. Thus, this novel combination of DispersinB® and Acticoat™, an antimicrobial dressing, prompts clinical evaluation for potential applications in biofilm-based chronic wound management.

Meta-analysis of the effectiveness of surgical scalpel or diathermy in making abdominal skin incisions.

LENUS (Irish Health Repository)

Ahmad, Nasir Zaheer

2012-02-01

BACKGROUND: Surgical scalpels are traditionally used to make skin incisions. Diathermy incisions on contrary are less popular among the surgeons. The aim of this meta-analysis was to compare the effectiveness of both techniques and address the common fallacies about diathermy incisions. METHODS: A literature search of MEDLINE and Cochrane databases was done, using the keywords diathermy, cold scalpel, and incisions. Eleven clinical trials comparing both methods of making skin incisions were selected for meta-analysis. The end points compared included postoperative wound infection, pain in first 24 hours after surgery, time taken to complete the incisions, and incision-related blood loss. RESULTS: Postoperative wound infection rate was comparable in both techniques (P = 0.147, odds ratio = 1.257 and 95% CI = 0.923-1.711). Postoperative pain was significantly less with diathermy incisions in first 24 hours (P = 0.031, weighted mean difference = 0.852 and 95% CI = 0.076-1.628). Similarly, the time taken to complete the incision and incision-related blood loss was significantly less with diathermy incisions (95% CI = 0.245-0.502 and 0.548-1.020, respectively). CONCLUSION: Diathermy incisions are equally prone to get wound infection, as do the incisions made with scalpel. Furthermore, lower incidence of early postoperative pain, swiftness of the technique, and a reduced blood loss are the encouraging facts supporting routine use of diathermy for abdominal skin incisions after taking careful precautions.

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 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 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.

Purpose: To evaluate the natural history of children with abdominal Burkitt's lymphoma who had complete clinical remission and residual abdominal mass after treatment. Material and methods: The charts and imaging findings of all children with abdominal Burkitt's lymphoma treated and followed at our medical center between 1988 and 1999 were reviewed for the presence, management, clinical course, and prognosis of residual mass. Results: Only children who achieved complete clinical remission were included. The study group consisted of 33 children (20 boys and 13 girls) aged 2.6-17.6 years (mean 7.2 years). Of these, seven (20.6 %) were found to have a residual abdominal mass. Two underwent second-look operation with no evidence of viable tumor on histology. The remaining five were followed by imaging studies for 2.2-9.1 years (mean 6.1 years); none relapsed. Conclusion: Residual mass is not uncommon in children with abdominal Burkitt's lymphoma. The presence of residual mass in a child with complete clinical remission does not alter the long-term prognosis. Therefore, in children with Burkitt's lymphoma and residual mass with no other signs of disease activity, expectant watching may be appropriate. (orig.)

The electric field near human skin wounds declines with age and provides a noninvasive indicator of wound healing.

Due to the transepidermal potential of 15-50 mV, inside positive, an injury current is driven out of all human skin wounds. The flow of this current generates a lateral electric field within the epidermis that is more negative at the wound edge than at regions more lateral from the wound edge. Electric fields in this region could be as large as 40 mV/mm, and electric fields of this magnitude have been shown to stimulate human keratinocyte migration toward the wounded region. After flowing out of the wound, the current returns through the space between the epidermis and stratum corneum, generating a lateral field above the epidermis in the opposite direction. Here, we report the results from the first clinical trial designed to measure this lateral electric field adjacent to human skin wounds noninvasively. Using a new instrument, the Dermacorder®, we found that the mean lateral electric field in the space between the epidermis and stratum corneum adjacent to a lancet wound in 18-25-year-olds is 107-148 mV/mm, 48% larger on average than that in 65-80-year-olds. We also conducted extensive measurements of the lateral electric field adjacent to mouse wounds as they healed and compared this field with histological sections through the wound to determine the correlation between the electric field and the rate of epithelial wound closure. Immediately after wounding, the average lateral electric field was 122 ± 9 mV/mm. When the wound is filled in with a thick, disorganized epidermal layer, the mean field falls to 79 ± 4 mV/mm. Once this epidermis forms a compact structure with only three cell layers, the mean field is 59 ± 5 mV/mm. Thus, the peak-to-peak spatial variation in surface potential is largest in fresh wounds and slowly declines as the wound closes. The rate of wound healing is slightly greater when wounds are kept moist as expected, but we could find no correlation between the amplitude of the electric field and the rate of wound

Intraperitoneal And Incisional Bupivacaine Analgesia For Major Abdominal/Gynecologic Surgery: A Placebocontrolled

2006-05-01

Full Text Available Background:Postoperative pain is an important surgical problem. Recent studies in pain pathophysiology have led to the hypothesis that with perioperative administration of analgesics (pre-emptive analgesia it may be possible to prevent or reduce postoperative pain. This study was planned to investigate the efficacy of pre-emptive analgesia on postoperative pain after major gynecologic abdominal surgeries. Methods: In this prospective, double-blinded, randomized, and placebocontrolled trial, 60 ASA physical status I and II patients undergoing major abdominal gynecologic surgeries were randomized to receive 45 mL of bupivacaine 0.375% or 45mL of normal saline; 30 mL and 15 mL of the treatment solution was administered into the peritoneal cavity and incision, respectively, before wound closure. The pain score of the patients was evaluated by the visual analogue scale (VAS on awakening, and at 6, 12, and 24h after surgery. Time to first analgesia request and total analgesic requirements in the first 24h were recorded. Results: Pain scores were significantly higher in the placebo group than in the bupivacaine group on awakening (5.98±1.01 v.s 1.05±1.05; p<0.001, and at 6h after surgery (5.37±0.85 vs. 2.51±1.02; p<0.001. First request to analgesia was significantly longer in the bupivacaine patients than in the placebo group (5.87±3.04 h vs.1.35±0.36; p<0.001.Meperidine consumption over 24h was 96.00 ±17.53 mg in the placebo group compared with 23.28 ±14.89 mg in the bupivacaine patients (p<0.001.Conclusion:A combination of intraperitoneal and incisional bupivacaine infiltration at the end of abdominal gynecologic surgeries reduces postoperative pain on awakening and for 6 hours after surgery, and provides significant opioidsparing analgesia for 24 h after gynecologic abdominal surgeries.

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

New techniques for wound debridement.

Madhok, Brijesh M; Vowden, Kathryn; Vowden, Peter

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.

The increasing numbers of cases of wound disease are now posing a big challenge in China. For more convenience of wound patients, wound management in community health care centers under the supervision of a specialist at general hospitals is an ideal solution. To ensure an accurate diagnosis in community health clinics, it is important that "the same language" for wound description, which may be composed of unified format description, including wound image, must be achieved. We developed a wound information management system that was built up by acquisition terminal, wound description, data bank, and related software. In this system, a 3G mobile phone was applied as acquisition terminal, which could be used to access to the data bank. This documentation system was thought to be an appropriate proposal for community wound care because of its objectivity, uniformity, and facilitation. It also provides possibility for epidemiological study in the future. © The Author(s) 2014.

Our group has developed a bipolar bioimpedance measurement-based method for determining the state of wound healing. The objective of this study was to assess the capability of the method. To assess the performance of the method, we arranged a follow-up study of four acute wounds. The wounds were measured using the method and photographed throughout the healing process. Initially the bioimpedance of the wounds was significantly lower than the impedance of the undamaged skin, used as a baseline. Gradually, as healing progressed, the wound impedance increased and finally reached the impedance of the undamaged skin. The clinical appearance of the wounds examined in this study corresponded well with the parameters derived from the bioimpedance data. Hard-to-heal wounds are a significant and growing socioeconomic burden, especially in the developed countries, due to aging populations and to the increasing prevalence of various lifestyle related diseases. The assessment and the monitoring of chronic wounds are mainly based on visual inspection by medical professionals. The dressings covering the wound must be removed before assessment; this may disturb the wound healing process and significantly increases the work effort of the medical staff. There is a need for an objective and quantitative method for determining the status of a wound without removing the wound dressings. This study provided evidence of the capability of the bioimpedance based method for assessing the wound status. In the future measurements with the method should be extended to concern hard-to-heal wounds.

Dynamic CT in the abdominal organ, 2. Dynamics in the abdominal malignancies

The potential role of the abdominal dynamic CT in malignant tumors was evaluated. Among total of 112 cases dynamically studied included were, 22 cases of abdominal malignancies, renal cell carcinoma in 7, hepatocellular carcinoma in 7, metastatic liver tumor in 5, renal pelvic carcinoma in 2, and pancreatic cystadenocarcinoma in one. The results led to the following advantages of the abdominal dynamic CT over conventional CT. (1) The tumor thrombus and the lymphnode involvement could be better demonstrated. (2) The tumor vessels and the tumor stain could be depicted. (3) The extent of the tumor in the parenchyma could be better appreciated. The more invasive catheter angiography would likely to be replaced by the abdominal dynamic CT in the selected case.

Hanna, Dominique; Cloutier, Richard; Lapointe, Roch; Desgagné, Antoine

2004-01-01

Elephantiasis is a well-known condition in dermatology usually affecting the legs and external genitalia. It is characterized by chronic inflammation and obstruction of the lymphatic channels and by hypertrophy of the skin and subcutaneous tissues. The etiology is either idiopathic or caused by a variety of conditions such as chronic filarial disease, leprosy, leishmaniasis, and chronic recurrent cellulites. Elephantiasis of the abdominal wall is very rare. A complete review of the English and French literature showed only two cases reported in 1966 and 1973, respectively. We report a third case of abdominal elephantiasis and we briefly review this entity. We present the case of a 51-year-old woman who had progressively developed an enormous pediculated abdominal mass hanging down her knees. The skin was thickened, hyperpigmented, and fissured. She had a history of multiple abdominal cellulites. She underwent an abdominal lipectomy. Histopathology of the specimen confirmed the diagnosis of abdominal elephantiasis. Abdominal elephantiasis is a rare disease that represents end-stage failure of lymph drainage. Lipectomy should be considered in the management of this condition.

Modern collagen wound dressings: function and purpose.

Science.gov (United States)

Fleck, Cynthia Ann; Simman, Richard

2010-09-01

Collagen, which is produced by fibroblasts, is the most abundant protein in the human body. A natural structural protein, collagen is involved in all 3 phases of the wound-healing cascade. It stimulates cellular migration and contributes to new tissue development. Because of their chemotactic properties on wound fibroblasts, collagen dressings encourage the deposition and organization of newly formed collagen, creating an environment that fosters healing. Collagen-based biomaterials stimulate and recruit specific cells, such as macrophages and fibroblasts, along the healing cascade to enhance and influence wound healing. These biomaterials can provide moisture or absorption, depending on the delivery system. Collagen dressings are easy to apply and remove and are conformable. Collagen dressings are usually formulated with bovine, avian, or porcine collagen. Oxidized regenerated cellulose, a plant-based material, has been combined with collagen to produce a dressing capable of binding to and protecting growth factors by binding and inactivating matrix metalloproteinases in the wound environment. The increased understanding of the biochemical processes involved in chronic wound healing allows the design of wound care products aimed at correcting imbalances in the wound microenvironment. Traditional advanced wound care products tend to address the wound's macroenvironment, including moist wound environment control, fluid management, and controlled transpiration of wound fluids. The newer class of biomaterials and wound-healing agents, such as collagen and growth factors, targets specific defects in the chronic wound environment. In vitro laboratory data point to the possibility that these agents benefit the wound healing process at a biochemical level. Considerable evidence has indicated that collagen-based dressings may be capable of stimulating healing by manipulating wound biochemistry.

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.

Wound ballistics examines the specific effect, namely the wound profile, of bullets on the body by firing at synthetic models made of ordnance gelatine, glycerin soap and synthetic bones, validated with real cases from (battlefield) surgery and forensic pathology. Wound profile refers to the penetration depth, the bullet deformation/ fragmentation, the diameter of the permanent and the temporary wound cavity. Knowing these features and the used ammunition a surgeon can rapidly assess the amount damage within a patient. The forensic pathologist can draw conclusions as to the used ammunition based on the wound profile. By measuring of the destructive capability of different ammunition types, wound ballistics lays the foundation for guidelines concerning the maximum effect of military ammunition.

Full Text Available Beatrice Scicchitano,1 Gareth Humphreys,1 Sally G Mitton,2 Thiagarajan Jaiganesh1 1Children's Emergency Department, 2Department of Paediatric Gastroenterology, St Georges Hospital, St Georges Healthcare NHS Trust, Tooting, London, United Kingdom Abstract: The childhood condition of abdominal migraine has been described under many different synonyms, including "abdominal epilepsy", "recurrent abdominal pain", "cyclical vomiting syndrome", and "functional gastrointestinal disorder". In the early literature, abdominal migraine is included in the "childhood periodic syndrome", first described by Wyllie and Schlesinger in 1933. Abdominal migraine has emerged over the last century as a diagnostic entity in its own right thanks to the development of well defined diagnostic criteria and its recent inclusion in the International Headache Society's Classification of Headache disorders. Despite this progress, little is known about the pathophysiology of the condition, and the treatment options are poorly defined. Here we summarize the recent literature, with particular focus on establishing the diagnosis of abdominal migraine and its pathophysiology, and suggest an approach to management.

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.

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

General concept of wound healing, revisited

Theddeus O.H. Prasetyono

Full Text Available Wound healing is a transition of processes which is also recognized as one of the most complex processes in human physiology. Complex series of reactions and interactions among cells and mediators take place in the healing process of wound involving cellular and molecular events. The inflammatory phase is naturally intended to remove devitalized tissue and prevent invasive infection. The proliferative phase is characterized by the formation of granulation tissue within the wound bed, composed of new capillary network, fibroblast, and macrophages in a loose arrangement of supporting structure. This second phase lasts from day 8 to 21 after the injury is also the phase for epithelialisation. The natural period of proliferative phase is a reflection for us in treating wound to reach the goal which ultimately defines as closed wound. The final maturation phase is also characterized by the balancing between deposition of collagen and its degradation. There are at least three prerequisites which are ideal local conditions for the nature of wound to go on a normal process of healing i.e. 1 all tissue involved in the wound and surrounding should be vital, 2 no foreign bodies in the wound, and 3 free from excessive contamination/infection. The author formulated a step ladder of thinking in regards of healing intentions covering all acute and chronic wounds. Regarding the “hierarchy” of healing intention, the fi rst and ideal choice to heal wounds is by primary intention followed by tertiary intention and lastly the secondary intention.

The purpose of this study was to investigate the influence of different hydrophilic polymers on the swelling, bioadhesion and mechanical strength of hydrocolloid wound dressings (HCDs) in order to provide an appropriate composition for a hydrocolloid wound dressing system. In this study, the HCDs were prepared with styrene-isoprene-styrene copolymer (SIS) and polyisobutylene (PIB) as the base using a hot melting method. Additionally, numerous SIS/PIB-based HCDs were prepared with six hydrophilic polymers, and their wound dressing properties were assessed. Finally, the wound healing efficacy of the selected formulations was compared to a commercial wound dressing. The swelling ratio, bioadhesive force and mechanical strengths of HCDs were increased in the order of sodium alginate>sodium CMC=poloxamer=HPMC>PVA=PVP, sodium alginate>sodium CMC=poloxamer>PVA>HPMC=PVP and sodium alginate≥PVA>PVP=HPMC=sodium CMC>poloxamer, respectively. Among the hydrophilic polymers tested, sodium alginate most enhanced the swelling capacity, bioadhesive force and mechanical strengths. Thus, the hydrophilic polymers played great role in the swelling, bioadhesion and mechanical strength of SIS/PIB-based HCDs. The HCD formulation composed of PIB, SIS, liquid paraffin and sodium alginate at the weight ratio of 20/25/12/43 gave better wound dressing properties and more excellent wound healing efficacy than the commercial wound dressing. Therefore, the novel HCD formulation could be a promising hydrocolloid system for wound dressings. Copyright © 2016 Elsevier B.V. All rights reserved.

Debridement and wound bed preparation.

Falabella, Anna F

2006-01-01

Debridement can play a vital role in wound bed preparation and the removal of barriers that impair wound healing. 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.

To provide information about a study using a new process for continuous monitoring to improve chronic wound care quality.This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care.After completing this continuing education activity, you should be better able to:1. Recognize problems associated with chronic wound care.2. Identify methods used in this project to improve care.3. Illustrate the findings from this and similar projects and implications for providing improved wound care.Patients with chronic wounds require complex care because of comorbidities that can affect healing. Therefore, the goal of this project was to develop a system of reviewing all hospitalized patients seen by the study authors' wound care service on a weekly basis to decrease readmissions, morbidity, and mortality. Weekly multidisciplinary conferences were conducted to evaluate patient data and systematically assess for adherence to wound care protocols, as well as to create and modify patient care plans. This review of pathology and the performance of root-cause analyses often led to improved patient care.

Changing patterns in the management of splenic trauma: the impact of nonoperative management.

Pachter, H L; Guth, A A; Hofstetter, S R; Spencer, F C

1998-01-01

OBJECTIVE: The recognition that splenectomy renders patients susceptible to lifelong risks of septic complications has led to routine attempts at splenic conservation after trauma. In 1990, the authors reported that over an 11-year study period involving 193 patients, splenorrhaphy was the most common splenic salvage method (66% overall) noted, with nonoperative management employed in only 13% of blunt splenic injuries. This report describes changing patterns of therapy in 190 consecutive patients with splenic injuries seen during a subsequent 6-year period (1990 to 1996). An algorithmic approach for patient management and pitfalls to be avoided to ensure safe nonoperative management are detailed. METHODS: Nonoperative management criteria included hemodynamic stability and computed tomographic examination without shattered spleen or other injuries requiring celiotomy. RESULTS: Of 190 consecutive patients, 102 (54%) were managed nonoperatively: 96 (65%) of 147 patients with blunt splenic injuries, which included 15 patients with intrinsic splenic pathology, and 6 hemodynamically stable patients with isolated stab wounds (24% of all splenic stab wounds). Fifty-six patients underwent splenectomy (29%) and 32 splenorrhaphy (17%). The mean transfusion requirement was 6 units for splenectomy survivors and 0.8 units for nonoperative therapy (85% received no transfusions). Fifteen of the 16 major infectious complications that occurred followed splenectomy. Two patients failed nonoperative therapy (2%) and underwent splenectomy, and one patient required splenectomy after partial splenic resection. There no missed enteric injuries in patients managed nonoperatively. The overall mortality rate was 5.2%, with no deaths following nonoperative management. CONCLUSIONS: Nonoperative management of blunt splenic injuries has replaced splenorrhaphy as the most common method of splenic conservation. The criteria have been extended to include patients previously excluded from this form

During the last four years 102 patients with abdominal trauma were examined by CT for preoperative evaluation in our hospital. In 35 patients (34 %), the CT scans revealed no abnormal findings. They were all managed conservatively except for one case of perforated small bowel. In 67 patients (66 %) CT revealed evidences of substantial abdominal or retroperitoneal trauma. In 30 of them CT findings were confirmed by surgery. Hepatic injury is usually easily recognized by CT. CT is also useful for the detection of renal or splenic injuries. The majority of those parenchymatous organ injuries were successfully managed with conservative therapy, despite apparent traumatic lesions revealed by CT. Repeat CT scans is proved to be very useful to follow the changes of these traumatic lesions. In conclusion, application of abdominal CT is extremely useful for the initial decision making in treatment of patients with abdominal trauma and for the follow-up observation of injured lesions.

A multiscale mechanics approach to the characterization of murine excisional wounds subjected to uniaxial tensile loading is presented. Local strain analysis at a physiological level of tension uncovers the presence of two distinct regions within the wound: i) a very compliant peripheral cushion and ii) a core area undergoing modest deformation. Microstructural visualizations of stretched wound specimens show negligible engagement of the collagen located in the center of a 7-day old wound; fibers remain coiled despite the applied tension, confirming the existence of a mechanically isolated wound core. The compliant cushion located at the wound periphery appears to protect the newly-formed tissue from excessive deformation during the phase of new tissue formation. The early remodeling phase (day 14) is characterized by a restored mechanical connection between far field and wound center. The latter remains less deformable, a characteristic possibly required for cell activities during tissue remodeling. The distribution of fibrillary collagens at these two time points corresponds well to the identified heterogeneity of mechanical properties of the wound region. This novel approach provides new insight into the mechanical properties of wounded skin and will be applicable to the analysis of compound-treated wounds or wounds in genetically modified tissue. Biophysical characterization of healing wounds is crucial to assess the recovery of the skin barrier function and the associated mechanobiological processes. For the first time, we performed highly resolved local deformation analysis to identify mechanical characteristics of the wound and its periphery. Our results reveal the presence of a compliant cushion surrounding a stiffer wound core; we refer to this heterogeneous mechanical behavior as "mechanical fingerprint" of the wound. The mechanical response is shown to progress towards that of the intact skin as healing takes place. Histology and multiphoton microscopy

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.

Here, we define dynamic reciprocity (DR) as an ongoing, bidirectional interaction amongst cells and their surrounding microenvironment. In the review, we posit that DR is especially meaningful during wound healing as the DR-driven biochemical, biophysical and cellular responses to injury play pivotal roles in regulating tissue regenerative responses. Such cell-extracellular matrix interactions not only guide and regulate cellular morphology, but cellular differentiation, migration, proliferation, and survival during tissue development, including e.g. embryogenesis, angiogenesis, as well as during pathologic processes including cancer diabetes, hypertension and chronic wound healing. Herein, we examine DR within the wound microenvironment while considering specific examples across acute and chronic wound healing. This review also considers how a number of hypotheses that attempt to explain chronic wound pathophysiology, which may be understood within the DR framework. The implications of applying the principles of dynamic reciprocity to optimize wound care practice and future development of innovative wound healing therapeutics are also briefly considered.

Wound healing is an intricate process that requires complex coordination between many cell types and an appropriate extracellular microenvironment. Chronic wounds often suffer from high protease activity, persistent infection, excess inflammation, and hypoxia. While there has been intense investigation to find new methods to improve cutaneous wound care, the management of chronic wounds, burns, and skin wound infection remain challenging clinical problems. Ideally, advanced wound dressings can provide enhanced healing and bridge the gaps in the healing processes that prevent chronic wounds from healing. These technologies have great potential for improving outcomes in patients with poorly healing wounds but face significant barriers in addressing the heterogeneity and clinical complexity of chronic or severe wounds. Active wound dressings aim to enhance the natural healing process and work to counter many aspects that plague poorly healing wounds, including excessive inflammation, ischemia, scarring, and wound infection. This review paper discusses recent advances in the development of biomaterials and nanoparticle therapeutics to enhance wound healing. In particular, this review focuses on the novel cutaneous wound treatments that have undergone significant preclinical development or are currently used in clinical practice. PMID:27843895

Abdominal epilepsy (AE) is a rather uncommon clinical entity in children that might create diagnostic confusion especially when it lacks the typical manifestations of an epileptic seizure. We report the case of a young boy having apparently unexplained episodes of paroxysmal abdominal symptoms with no other suggestion of an underlying epileptic disorder. The case also explains how the clinical presentation can be misleading unless a high index of suspicion is maintained to reach the ultimate diagnosis. (author)

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.

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

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.

Honey: an immunomodulator in wound healing.

Science.gov (United States)

Majtan, Juraj

2014-01-01

Honey is a popular natural product that is used in the treatment of burns and a broad spectrum of injuries, in particular chronic wounds. The antibacterial potential of honey has been considered the exclusive criterion for its wound healing properties. The antibacterial activity of honey has recently been fully characterized in medical-grade honeys. Recently, the multifunctional immunomodulatory properties of honey have attracted much attention. The aim of this review is to provide closer insight into the potential immunomodulatory effects of honey in wound healing. Honey and its components are able to either stimulate or inhibit the release of certain cytokines (tumor necrosis factor-α, interleukin-1β, interleukin-6) from human monocytes and macrophages, depending on wound condition. Similarly, honey seems to either reduce or activate the production of reactive oxygen species from neutrophils, also depending on the wound microenvironment. The honey-induced activation of both types of immune cells could promote debridement of a wound and speed up the repair process. Similarly, human keratinocytes, fibroblasts, and endothelial cell responses (e.g., cell migration and proliferation, collagen matrix production, chemotaxis) are positively affected in the presence of honey; thus, honey may accelerate reepithelization and wound closure. The immunomodulatory activity of honey is highly complex because of the involvement of multiple quantitatively variable compounds among honeys of different origins. The identification of these individual compounds and their contributions to wound healing is crucial for a better understanding of the mechanisms behind honey-mediated healing of chronic wounds. © 2014 by the Wound Healing Society.

Cationic antimicrobial peptides are multifunctional molecules that have a high potential as therapeutic agents. We have identified a histone H1-derived peptide from the Komodo dragon ( Varanus komodoensis) , called VK25. Using this peptide as inspiration, we designed a synthetic peptide called DRGN-1. We evaluated the antimicrobial and anti-biofilm activity of both peptides against Pseudomonas aeruginosa and Staphylococcus aureus . DRGN-1, more than VK25, exhibited potent antimicrobial and anti-biofilm activity, and permeabilized bacterial membranes. Wound healing was significantly enhanced by DRGN-1 in both uninfected and mixed biofilm ( Pseudomonas aeruginosa and Staphylococcus aureus )-infected murine wounds. In a scratch wound closure assay used to elucidate the wound healing mechanism, the peptide promoted the migration of HEKa keratinocyte cells, which was inhibited by mitomycin C (proliferation inhibitor) and AG1478 (epidermal growth factor receptor inhibitor). DRGN-1 also activated the EGFR-STAT1/3 pathway. Thus, DRGN-1 is a candidate for use as a topical wound treatment. Wound infections are a major concern; made increasingly complicated by the emerging, rapid spread of bacterial resistance. The novel synthetic peptide DRGN-1 (inspired by a peptide identified from Komodo dragon) exhibits pathogen-directed and host-directed activities in promoting the clearance and healing of polymicrobial ( Pseudomonas aeruginosa & Staphylococcus aureus ) biofilm infected wounds. The effectiveness of this peptide cannot be attributed solely to its ability to act upon the bacteria and disrupt the biofilm, but also reflects the peptide's ability to promsote keratinocyte migration. When applied in a murine model, infected wounds treated with DRGN-1 healed significantly faster than did untreated wounds, or wounds treated with other peptides. The host-directed mechanism of action was determined to be via the EGFR-STAT1/3 pathway. The pathogen-directed mechanism of action was

Injectable scaffolds present compelling opportunities for wound repair and regeneration due to their ability to fill irregularly shaped defects and deliver biologics such as growth factors. In this study, we investigated the properties of injectable polyurethane biocomposite scaffolds and their application in cutaneous wound repair using a rat excisional model. The scaffolds have a minimal reaction exotherm and clinically relevant working and setting times. Moreover, the biocomposites have mechanical and thermal properties consistent with rubbery elastomers. In the rat excisional wound model, injection of settable biocomposite scaffolds stented the wounds at early time points, resulting in a regenerative rather than a scarring phenotype at later time points. Measurements of wound width and thickness revealed that the treated wounds were less contracted at day 7 compared to blank wounds. Analysis of cell proliferation and apoptosis showed that the scaffolds were biocompatible and supported tissue ingrowth. Myofibroblast formation and collagen fiber organization provided evidence that the scaffolds have a positive effect on extracellular matrix remodeling by disrupting the formation of an aligned matrix under elevated tension. In summary, we have developed an injectable biodegradable polyurethane biocomposite scaffold that enhances cutaneous wound healing in a rat model. PMID:22105887

[Chronic wounds as a public health problem].

Chronic wounds represent a significant burden to patients, health care professionals and the entire health care system. Regarding the healing process, wounds can be classified as acute or chronic wounds. A wound is considered chronic if healing does not occur within the expected period according to the wound etiology and localization. Chronic wounds can be classified as typical and atypical. The majority of wounds (95 percent) are typical ones, which include ischemic, neurotrophic and hypostatic ulcers and two separate entities: diabetic foot and decubital ulcers. Eighty percent of chronic wounds localized on lower leg are the result of chronic venous insufficiency, in 5-10 percent the cause is of arterial etiology, whereas the rest are mostly neuropathic ulcers. Chronic wounds significantly decrease the quality of life of patients by requiring continuous topical treatment, causing immobility and pain in a high percentage of patients. Chronic wounds affect elderly population. Chronic leg ulcers affect 0.6-3 percent of those aged over 60, increasing to over 5 percent of those aged over 80. Emergence of chronic wounds is a substantial socioeconomic problem as 1-2 percent of western population will suffer from it. This estimate is expected to rise due to the increasing proportion of elderly population along with the diabetic and obesity epidemic. It has been proved that chronic wounds account for the large proportion of costs in the health care system, even in rich societies. Socioeconomically, the management of chronic wounds reaches a total of 2-4 percent of the health budget in western countries. Treatment costs for some other diseases are not irrelevant, nor are the method and materials used for treating these wounds. Considering etiologic factors, a chronic wound demands a multidisciplinary approach with great efforts of health care professionals to treat it more efficiently, more simply and more painlessly for the patient, as well as more inexpensively for

Functional abdominal pain.

Science.gov (United States)

Grover, Madhusudan; Drossman, Douglas A

2010-10-01

Functional abdominal pain syndrome (FAPS) is a relatively less common functional gastrointestinal (GI) disorder defined by the presence of constant or frequently recurring abdominal pain that is not associated with eating, change in bowel habits, or menstrual periods (Drossman Gastroenterology 130:1377-1390, 2006), which points to a more centrally targeted (spinal and supraspinal) basis for the symptoms. However, FAPS is frequently confused with irritable bowel syndrome and other functional GI disorders in which abdominal pain is associated with eating and bowel movements. FAPS also differs from chronic abdominal pain associated with entities such as chronic pancreatitis or chronic inflammatory bowel disease, in which the pain is associated with peripherally acting factors (eg, gut inflammation or injury). Given the central contribution to the pain experience, concomitant psychosocial disturbances are common and strongly influence the clinical expression of FAPS, which also by definition is associated with loss of daily functioning. These factors make it critical to use a biopsychosocial construct to understand and manage FAPS, because gut-directed treatments are usually not successful in managing this condition.

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

Full Text Available Effective assessment and management of wound pain can facilitate both improvements in healing rates and overall quality of life. From a pharmacological perspective, topical application of nonsteroidal anti-inflammatory drugs in the form of film wound dressings may be a good choice. Thus, the aim of this work was to develop novel layered film wound dressings containing ibuprofen based on partially substituted fibrous sodium carboxymethylcellulose (nonwoven textile Hcel NaT. To this end, an innovative solvent casting method using a sequential coating technique has been applied. The concentration of ibuprofen which was incorporated as an acetone solution or as a suspension in a sodium carboxymethylcellulose dispersion was 0.5 mg/cm2 and 1.0 mg/cm2 of film. Results showed that developed films had adequate mechanical and swelling properties and an advantageous acidic surface pH for wound application. An in vitro drug release study implied that layered films retained the drug for a longer period of time and thus could minimize the frequency of changing the dressing. Films with suspended ibuprofen demonstrated higher drug content uniformity and superior in vitro drug release characteristics in comparison with ibuprofen incorporation as an acetone solution. Prepared films could be potential wound dressings for the effective treatment of wound pain in low exuding wounds.

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

The level of inter-observer agreement of abdominal computed tomography (CT) in unselected patients presenting with acute abdominal pain at the Emergency Department (ED) was evaluated. Two hundred consecutive patients with acute abdominal pain were prospectively included. Multi-slice CT was performed in all patients with intravenous contrast medium only. Three radiologists independently read all CT examinations. They recorded specific radiological features and a final diagnosis on a case record form. We calculated the proportion of agreement and kappa values, for overall, urgent and frequently occurring diagnoses. The mean age of the evaluated patients was 46 years (range 19-94), of which 54% were women. Overall agreement on diagnoses was good, with a median kappa of 0.66.

Hiebert, John M; Robson, Martin C

2016-01-01

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

Abdominal emergencies

Full text: There are numerous conditions that affect mainly or exclusively the pediatric population. These constitute true emergencies, related to patient's health. Delay in diagnosis and treatment of abdominal non-traumatic emergencies may result in rapid deterioration, peritonitis, sepsis, even death or in severe complications with subsequent morbidity. Abdominal emergencies in children mostly present with pain, tenderness, occasionally coupled by vomiting, fever, abdominal distension, and failure to pass meconium or stools. Diarrhea, blood per rectum, abnormal laboratory tests and lethargy may also be manifestations of acute abdominal conditions. Abdominal emergencies have a different aetiology, depending on age and whether the pain is acute or chronic. Symptoms have to be matched with age and gender. Newborns up to 1 months of age may have congenital diseases: atresia, low obstruction including Hirschsprung's disease, meconium ileus. Meconium plug is one of the commonest cause of low obstruction in newborns that may also develop necrotizing enterocolitis, incarcerated inguinal hernia and mid-gut volvulus. Past the immediate postnatal period, any duodenal obstruction should be considered midgut volvulus until proven otherwise and patients should undergo ultrasonography and/or properly performed upper GI contrast study that records the exact position of the deduno-jejunal junction. Infants 6 months-2 years carry the risk of intussusception, mid-gut volvulus, perforation, acute pyelonephritis. Preschool and school-aged children 2-12 years carry the risk of appendicitis, genito-urinary abnormalities including torsion, urachal abnormalities, haemolytic uremic syndrome and Henoch-Schonlein purpura. Children above 12 years suffer from the same conditions as in adults. Most conditions may affect any age despite age predilection. Abdominal solid organ ultrasonography (US) coupled with gastrointestinal ultrasonography is the principle imaging modality in radiosensitive

Cytokines play important roles in the wound healing process through various signalling pathways. The JAK-STAT pathway is utilised by most cytokines for signal transduction and is regulated by a variety of molecules, including suppressor of cytokine signalling (SOCS) proteins. SOCS are associated with inflammatory diseases and have an impact on cytokines, growth factors and key cell types involved in the wound-healing process. SOCS, a negative regulator of cytokine signalling, may hold the potential to regulate cytokine-induced signalling in the chronic wound-healing process. Wound edge tissues were collected from chronic venous leg ulcer patients and classified as non-healing and healing wounds. The expression pattern of seven SOCSs members, at the transcript and protein level, were examined in these tissues using qPCR and immunohistochemistry. Significantly higher levels of SOCS3 (P=0.0284) and SOCS4 (P=0.0376) in non-healing chronic wounds compared to the healing/healed chronic wounds were observed at the transcript level. Relocalisation of SOCS3 protein in the non-healing wound environment was evident in the investigated chronic biopsies. Thus, the results show that the expression of SOCS transcript indicated that SOCS members may act as a prognostic biomarker of chronic wounds. PMID:27635428

Full Text Available BACKGROUND Delayed wound healing is a significant health problem, particularly in patients with compound fractures. It still remains a challenging task in orthopaedic surgery, which in addition to the pain and suffering, failure of the wound to heal, also imposes social and financial burdens. The aim of the study is to evaluate the results of vacuum-assisted wound therapy in patients with open musculoskeletal injuries. MATERIALS AND METHODS 30 patients of open musculoskeletal injuries underwent randomised trial of vacuum-assisted closure therapy versus standard wound therapy around the upper limb and lower limb. Mean patient age was 39 ± 18 years necrotic tissues were debrided before applying VAC therapy. Dressings were changed every 3 or 4 days. For standard wound therapy, debridement followed by daily dressings was done. Data Management and Statistical Analysis- The results obtained were subjected to statistical analysis. RESULTS Granulation tissue status and skin healing is better in patients undergoing VAC therapy. Hospital stay of patients undergoing VAC therapy was also less. CONCLUSION Vacuum-assisted wound therapy was better method of wound management.

Wound healing consists of a complex series of convoluted processes which involve renewal of the skin after injury. ROS are involved in all phases of wound healing. A balance between oxidative and antioxidative forces is necessary for a favorable healing outcome. Astaxanthin, a member of the xanthophyll group, is considered a powerful antioxidant. In this study, we investigated the effect of topical astaxanthin on cutaneous wound healing. Full-thickness dermal wounds were created in 36 healthy female mice, which were divided into a control group and a group receiving 78.9 µM topical astaxanthin treatment twice daily for 15 days. Astaxanthin-treated wounds showed noticeable contraction by day 3 of treatment and complete wound closure by day 9, whereas the wounds of control mice revealed only partial epithelialization and still carried scabs. Wound healing biological markers including Col1A1 and bFGF were significantly increased in the astaxanthin-treated group since day 1. Interestingly, the oxidative stress marker iNOS showed a significantly lower expression in the study. The results indicate that astaxanthin is an effective compound for accelerating wound healing.

Full Text Available "Peritonitis fibrosa incapsulata", first described in 1907, is a condition characterized by encasement of the bowel with a thick fibrous membrane. This condition was renamed as "abdominal cocoon" in 1978. It presents as small bowel obstruction clinically. 35 cases of abdominal cocoon have been reported in the literature over the last three decades. Abdominal cocoon is more common in adolescent girls from tropical countries. Various etiologies have been described, including tubercular. It is treated surgically by releasing the entrapped bowel. We report a laparoscopic experience of tubercular abdominal cocoon and review the literature.

Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition. Copyright © 2016 SERAM.

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

Prophylactic Groin Wound Vacuum-assisted Therapy in Vascular Surgery Patients at Enhanced Risk for Postoperative Wound Infection.

Pesonen, Luke O; Halloran, Brian G; Aziz, Abdulhameed

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

Primary care health professionals, especially family physicians, see a variety of wounds, and yet-despite the frequency of providing wound care-many family physicians do not feel confident in wound care management. This is partly due to a lack of formal wound education in Family Medicine programs. While there are numerous electronic wound care resources available in the UK and North America, none were identified that address the specific need in supporting clinical decision-making in wound dressing selection. At the same time, healthcare providers are increasingly using technology in personal and professional contexts, and a logical extension is to use technology for knowledge translation strategies. This work developed a prototype mobile health software application named WounDS, designed to support clinical decision-making in selecting wound dressings. This article presents the development and evaluation plan for the WounDS app. WounDS has been developed on the iOS platform. The primary specification included ease of use, in that one of the primary influences in user adoption would be the ability to receive a wound dressing recommendation in under 30 seconds and under 5 taps on the screen. The WounDS app guides users through a series of binary decisions for assessing the wound and provides a wound dressing recommendation. The selection algorithm is based in best practices using the Wound Bed Preparation Paradigm. Current work is underway to examine the implementation needs for WounDS to be most effectively utilized and to pilot test its feasibility and use in clinical care. Data will be collected through user trials, focus groups, and user metadata will be collected within the app. Optimizing these preconditions will enable a subsequent phase of study to determine effects on clinical decision-making and clinical outcomes. WounDS is designed for knowledge translation, use of technology in clinical decision-making, and continuity of care. The benefits of WounDS

Anthropometric measurements can be used to define pediatric malnutrition. Our study aims to: (1) characterize the preoperative nutritional status of children undergoing abdominal or thoracic surgery, and (2) describe the associations between WHO-defined acute (stunting) and chronic (wasting) undernutrition (Z-scores +2) with 30-day postoperative outcomes. We queried the Pediatric NSQIP Participant Use File and extracted data on patients' age 29days to 18years who underwent abdominal or thoracic procedures. Normalized anthropometric measures were calculated, including weight-for-height for nutritional outlier status as an independent predictor of postoperative outcome. 23,714 children (88% ≥2y) were evaluated. 4272 (18%) were obese, while 2640 (11.1%) and 904 (3.8%) were stunted and wasted, respectively, after controlling for gender, ASA/procedure/wound classification, preoperative steroid use, need for preoperative nutritional support, and obese children had higher odds of SSIs (OR 1.29, 95% CI 1.1-1.5, p=0.001), while stunted children were at increased risk of any 30-day postoperative complication (OR 1.16, 95% CI 1.0-1.3, p=0.036). Children who are stunted or obese are at increased risk of adverse outcome after abdominal or thoracic surgery. III. Copyright © 2018 Elsevier Inc. All rights reserved.

Jasmonic acid (JA) and its methyl ester, methyl jasmonate (MeJA), are plant lipid derivatives that resemble mammalian eicosanoids in structure and biosynthesis. These compounds are proposed to play a role in plant wound and pathogen responses. Here we report the quantitative determination of JA/MeJA in planta by a procedure based on the use of [13C,2H3]MeJA as an internal standard. Wounded soybean (Glycine max [L] Merr. cv. Williams) stems rapidly accumulated MeJA and JA. Addition of MeJA to soybean suspension cultures also increased mRNA levels for three wound-responsive genes (chalcone synthase, vegetative storage protein, and proline-rich cell wall protein) suggesting a role for MeJA/JA in the mediation of several changes in gene expression associated with the plants' response to wounding.

Anterior gradient 2 (AGR2), a member of protein disulfide isomerase (PDI) family, is both located in cytoplasm and secreted into extracellular matrix. The orthologs of AGR2 have been linked to limb regeneration in newt and wound healing in zebrafish. In mammals, AGR2 influences multiple cell signaling pathways in tumor formation and in normal cell functions related to new tissue formation like angiogenesis. However, the function of AGR2 in mammalian wound healing remains unknown. This study aimed to investigate AGR2 expression and its function during skin wound healing and the possible application of external AGR2 in cutaneous wound to accelerate the healing process. Our results showed that AGR2 expression was induced in the migrating epidermal tongue and hyperplastic epidermis after skin excision. Topical application of recombinant AGR2 significantly accelerated wound-healing process by increasing the migration of keratinocytes (Kera.) and the recruitment of fibroblasts (Fibro.) near the wounded area. External AGR2 also promoted the migration of Kera. and Fibro. in vitro in a dose-dependent manner. The adhesion domain of AGR2 was required for the formation of focal adhesions in migrating Fibro., leading to the directional migration along AGR2 gradient. These results indicate that recombinant AGR2 accelerates skin wound healing through regulation of Kera. and Fibro. migration, thus demonstrating its potential utility as an alternative strategy of the therapeutics to accelerate the healing of acute or chronic skin wounds. © 2017 Federation of European Biochemical Societies.

Blunt abdominal trauma in children.

Schonfeld, Deborah; Lee, Lois K

2012-06-01

This review will examine the current evidence regarding pediatric blunt abdominal trauma and the physical exam findings, laboratory values, and radiographic imaging associated with the diagnosis of intra-abdominal injuries (IAI), as well as review the current literature on pediatric hollow viscus injuries and emergency department disposition after diagnosis. The importance of the seat belt sign on physical examination and screening laboratory data remains controversial, although screening hepatic enzymes are recommended in the evaluation of nonaccidental trauma to identify occult abdominal organ injuries. Focused Assessment with Sonography for Trauma (FAST) has modest sensitivity for hemoperitoneum and IAI in the pediatric trauma patient. Patients with concern for undiagnosed IAI, including bowel injury, may be considered for hospital admission and serial abdominal exams without an increased risk of complications, if an exploratory laparotomy is not performed emergently. Although the FAST exam is not recommended as the sole screening tool to rule out IAI in hemodynamically stable trauma patients, it may be used in conjunction with the physical exam and laboratory findings to identify children at risk for IAI. Children with a normal physical exam and normal abdominal CT may not require routine hospitalization after blunt abdominal trauma.

Negative Pressure Wound Therapy in Infected Wound following Posterior Spinal Instrumentation using Simple Self-assembled System: A Case Report

2014-07-01

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.

Wound healing studies, which have chiefly examined dermal tissues, have reported a female advantage in healing rates. In contrast, our laboratory recently demonstrated women heal mucosal wounds more slowly than men. We hypothesized sex hormones influence wound healing rates, possibly through their modulating effects on inflammation. This study involved 329 younger subjects aged 18-43 (165 women, 164 men) and 93 older subjects aged 50-88 (60 women, 33 men). A 3.5mm diameter wound was created on the hard oral palate and videographed daily to assess wound closure. Blood collected at the time of wounding was used to assess circulating testosterone, progesterone and estradiol levels, and in vitro cytokine production in response to LPS. No strong associations were observed between healing times and estradiol or progesterone levels. However, in younger subjects, lower testosterone levels related to faster wound closure. Conversely, in older women higher testosterone levels related to (1) lower inflammatory responses; and (2) faster healing times. No such relationships were seen in older men, or in women taking oral contraceptives or hormone replacement therapy [HRT]. Older women (50-54 years) not yet experiencing menopause healed similarly to younger women and dissimilarly from age-matched post-menopausal women. This suggests that the deleterious effects of aging on wound healing occur secondary to the effects of menopause. Supporting this, there was evidence in post-menopausal women that HRT augmented wound closure. Overall, this study suggests that human mucosal healing rates are modulated by testosterone levels. Based upon when between-group differences were observed, testosterone may impact upon the proliferative phase of healing which involves immune processes such as re-epithelialization and angiogenesis.

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.

Abdominal fat, and in particular, visceral adipose tissue (VAT), is the critical fat depot associated with metabolic aberrations. At present VAT can only be accurately measured by computed tomography (CT) or magnetic resonance imaging (MRI). This study was designed to compare a new abdominal bioelectrical impedance device against total abdominal adipose tissue (TAAT) and VAT area measurements made from an abdominal MRI scan, and to assess it’s reliability and accuracy.
