In South Africa, the leading cause of spinal cord injuries is motor vehicle accidents, followed by violence-related injuries, including gunshot injuries and stab wounds. Controversy regarding management persists. Magnetic resonance imaging (MRI) is the gold standard to rule out surgical causes of neurological deficit.
The objective of this study was to review mortality from external causes (accidental injury) in children and adolescents in systematically selected journals. This was a systematic review of the literature on mortality from accidental injury in children and adolescents. We searched the Pubrvled, Latin-American and Caribbean Health Sciences and Excerpta Medica databases for articles published between July of 2001 and June of 2011. National data from official agencies, retrieved by manual searches, were also reviewed. We reviewed 15 journal articles, the 2011 edition of a National Safety Council publication and 2010 statistical data from the Brazilian National Ministry of Health Mortality Database. Most published data were related to high-income countries. Mortality from accidental injury was highest among children less than 1 year of age. Accidental threats to breathing (non-drowning threats) constituted the leading cause of death among this age group in the published articles. Across the pediatric age group in the surveyed studies, traffic accidents were the leading cause of death, followed by accidental drowning and submersion. Traffic accidents constitute the leading external cause of accidental death among children in the countries understudy. However, infants were vulnerable to external causes, particularly to accidental non-drowning threats to breathing, and this age group had the highest mortality rates for external causes. Actions to reduce such events are suggested. Further studies investigating the occurrence of accidental deaths in low-income countries are needed to improve the understanding of these preventable events.
A burn is an inflammatory injury to the skin or other tissue due to contact with thermal, radioactive, electric, or chemical agents. Burn injury is an important cause of disability and death worldwide. Obesity is a significant public health problem, often causing underlying systemic inflammation. Studying the combined impact of burn injuries on obese patients has become critical to the successful treatment of these patients. The aim of this paper is to highlight the effect of inflammation associated with burn injuries on several body weight group in a rat study.
Bentonite, a montmorillonite clay, has been used as a classical remedy strategy for a long time. Recently, bentonite has been used as a raw material in cosmetic products because of its antibacterial and antioxidant properties. However, the therapeutic effect of bentonite on burn injuries has not yet been identified.
Currently available ocular moisture chambers are not adequate to manage the treatment of periocular burns, corneal injuries, and infection. The purpose of these studies was to demonstrate that a flexible, semi-transparent ocular wound chamber device adapted from technology currently used on dermal wounds is safe for use on corneal epithelial injuries.
Gun violence in the United States rose continuously from 2010 to 2022, spiking during the pandemic, and peaking in 2021 at 48,830 deaths (14.8 per 100,000). Previous reports investigated health and financial burden associated with gunshot wounds (GSWs) during 2004 to 2013; however estimates related specifically to head and neck (H&N) injuries have been lacking. This population-based study aims to examine incidence, morbidity, mortality, and health resource utilization of H&N injuries utilizing the Nationwide Inpatient Sample database.
Amniotic membrane grafts have some therapeutic potential for wounds healing. Early application of amniotic membrane turned out as beneficial in healing ulcers, burns, and dermal injuries. Since the second half of the 20th century, the autotransplants of amniotic/chorion tissue have been also used for the treatment of chronic neuropathic wounds, cornea surface injuries, pterygium and conjunctivochalasis, and dental and neurosurgical applications. The aim of this publication is to prepare a coherent overview of amniotic membrane derivatives use in the field of wound healing and also its efficacy. In total 60 publications and 39 posters from 2000-2020 were examined. In these examined publications of case studies with known study results was an assemblage of 1141 patients, and from this assemblage 977 were successfully cured. In case of posters, the assemblage is 570 patients and 513 successfully cured. From the investigated data it is clear that the treatment efficacy is very high-86% and 90%, respectively. Based on this information the use of the amniotic membrane for chronic wounds can be considered highly effective.
Burn injuries are a common hazard in the military, as fire is likely to be weaponized. Thus, it is important to find an effective substance to accelerate burn wound healing. This study used chitosan and gold nanoparticles (AuNPs) as wound dressings and investigated their effectiveness in femoral artery hemorrhage swine and rat burn models. Chitosan dressing has significant hemostatic properties compared with gauze. Histological results showed that burn wounds treated with chitosan or AuNP-coated chitosan dressings exhibited more cells and a continuous structure of the epidermis and dermis than those of the control and untreated lesion groups. Furthermore, both chitosan dressings have been shown to positively regulate the expression of genes- and cytokines/chemokines-related to the wound healing process; AuNP-coated chitosan significantly lessened severe sepsis and inflammation, balanced the activities of pro-fibrotic and anti-fibrotic ligands for tissue homeostasis, regulated angiogenesis, and inhibited apoptosis activity, thereby being beneficial for the burn microenvironment. Hence, chitosan alone or in combination with AuNPs represents a prospective therapeutic substance as a burn dressing which might be helpful for burn wound care. This study provides a novel hemostasis dressing for modern warfare that is simple to use by most medical and paramedical personnel handling for burn treatment.
Single trauma injuries or isolated fractures are often manageable and generally heal without complications. In contrast, high-energy trauma results in multi/poly-trauma injury patterns presenting imbalanced pro- and anti- inflammatory responses often leading to immune dysfunction. These injuries often exhibit delayed healing, leading to fibrosis of injury sites and delayed healing of fractures depending on the intensity of the compounding traumas. Immune dysfunction is accompanied by a temporal shift in the innate and adaptive immune cells distribution, triggered by the overwhelming release of an arsenal of inflammatory mediators such as complements, cytokines and damage associated molecular patterns (DAMPs) from necrotic cells. Recent studies have implicated this dysregulated inflammation in the poor prognosis of polytraumatic injuries, however, interventions focusing on immunomodulating inflammatory cellular composition and activation, if administered incorrectly, can result in immune suppression and unintended outcomes. Immunomodulation therapy is promising but should be conducted with consideration for the spatial and temporal distribution of the immune cells during impaired healing. This review describes the current state of knowledge in the spatiotemporal distribution patterns of immune cells at various stages during musculoskeletal wound healing, with a focus on recent advances in the field of Osteoimmunology, a study of the interface between the immune and skeletal systems, in long bone fractures. The goals of this review are to (1) discuss wound and fracture healing processes of normal and delayed healing in skeletal muscles and long bones; (2) provide a balanced perspective on temporal distributions of immune cells and skeletal cells during healing; and (3) highlight recent therapeutic interventions used to improve fracture healing. This review is intended to promote an understanding of the importance of inflammation during normal and delayed wound and fracture healing. Knowledge gained will be instrumental in developing novel immunomodulatory approaches for impaired healing.
For centuries, medicinal plants have been extensively used in wound healing of burn injuries. The aim of this study is to analyze comparatively the effects of curcumin and Hypericum perforatum (HP) on second-degree burn wounds in rats. Materials and Methods. This experimental study was conducted on 24 male Sprague-Dawley rats with second-degree burns. The animals were randomly divided into three groups. The burns were treated with curcumin (Group B) and Hypericum perforatum (HP) on second-degree burn wounds in rats.
The development of post-traumatic heterotopic ossification (HO) is a common, undesirable sequela in patients with high-energy (war-related) extremity injuries. While inflammatory and osteoinductive signaling pathways are known to be involved in the development and progression of post-traumatic HO, features of the structural microenvironment within which the ectopic bone begins to form remain poorly understood. Thus, increasing our knowledge of molecular and structural changes within the healing wound may help elucidate the pathogenesis of post-traumatic HO and aid in the development of specific treatment and/or prevention strategies.
Agriculture is one of the most hazardous economic sectors, and it accounts for many accidents and occupational diseases every year. In Italy, about one-third of injuries involve the upper extremity, with long-term consequences for the workers and economic damage for agricultural companies and farms. This systematic review describes upper limb injuries among farmworkers, especially hand injuries, and highlights the main dangerous risk factors. Literature review included articles published in the major databases (PubMed, Cochrane Library, Scopus), using a combination of some relevant keywords. This online search yielded 951 references; after selection, the authors analyzed 53 articles (3 narrative reviews and 50 original articles). From this analysis, it appears that younger male farmers are mostly involved, especially in the harvesting season. The upper limb and hand are often the body parts that sustain most damage as these are mostly involved in driving tractors or tools. The most frequent type of lesions are open wounds, lacerations, fractures, strains, and overexertion lesions. Sometimes, a distracting element (such as mobile phone use, quarrels, working hours load) is present; poor use of protective devices and lack of safety design in tools can also increase the risk of accidents. For these reasons, in the agricultural sector, a system of health promotion and good practices is needed to promote workers' awareness of the sources of risk, highlight more dangerous situations and apply organizational behavioral measures.
Urologic trauma is a well-known cause of urethral injury with a range of management recommendations. Retrograde urethrogram remains the preferred initial diagnostic modality to evaluate a suspected urethral injury. The management thereafter varies based on mechanism of injury. Iatrogenic urethral injury is often caused by traumatic catheterization and is best managed by an attempted catheterization performed by an experienced clinician or suprapubic catheter to maximize urinary drainage. Penetrating trauma, most commonly associated with gunshot wounds, can cause either an anterior and/or posterior urethral injury and is best treated with early operative repair. Blunt trauma, most commonly associated with straddle injuries and pelvic fractures, can be treated with either early primary endoscopic realignment or delayed urethroplasty after suprapubic cystostomy. With any of the above injury patterns and treatment options, a well thought out and regimented follow-up with a urologist is of utmost importance for accurate assessment of outcomes and appropriate management of complications.
Nursing home residents are at a greater risk of developing pressure injuries that develop into an open wound, which can become colonized with bacteria. Understanding the factors that influence microbial colonization of open wounds can lead to the prevention of infections. The relationship between bacteria found in urine and those in open wounds is currently unknown. To determine if bacterial species colonizing open wounds are also found in the urine, we conducted a pilot study with nursing home residents, comparing bacterial species present in the urine with those present in wounds between the umbilicus and mid-thigh. To identify microbial species that were present in both urine and open wound at one time point in one patient, standard clinical bacteriologic culture techniques followed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) were used, as well as 16S rRNA-encoding gene amplicon sequencing. We found some bacterial species detected in urine were also detected in open wounds in one individual at one time point, using both culture-dependent and -independent techniques. Bacterial species that were more often detected, using culture-dependent and -independent methods, at both sites included Enterococcus faecalis, Proteus mirabilis, Escherichia coli, and Providencia stuartii This pilot study provides evidence that bacterial species identified within the urine can also be identified in open wounds in the same patient at one point in time. Further studies are needed to investigate if these species are of the same lineage and if the urinary microbiota are able to seed colonization of open wounds below the umbilicus.IMPORTANCE Older adults, specifically those in nursing facilities, are more susceptible to developing chronic open nonhealing wounds. Chronic open nonhealing wounds severely impact an individual's quality of life and can lead to other comorbidities, such as infection. Recent evidence suggests that the open wound bacterial community can influence wound healing and repair. It is important to understand all sources of open wound contamination to improve preventative infection measures and treatment protocols. In this pilot study, we investigated if bacterial species isolated from urine can also be isolated from open wounds located between the levels of the umbilicus and mid-thigh in the same patient at the same point in time. A growing body of evidence suggests that urine can harbor a microbial community, even in asymptomatic individuals, and older adults are more prone to urinary incontinence. This is the first study to investigate bacterial species concordance between these two anatomical sites. We found, using both culture-dependent and -independent methods, that the same bacterial species can colonize both the urine and wound in one patient at one point in time. Further studies are needed to investigate if these species are of the same lineage and if the urinary microbiota are able to seed colonization of these types of open wounds.
Microbial contamination in combat wounds can lead to opportunistic infections and adverse outcomes. However, current microbiological detection has a limited ability to capture microbial functional genes. This work describes the application of targeted metagenomic sequencing to profile wound bioburden and capture relevant wound-associated signatures for clinical utility. Ultimately, the ability to detect such signatures will help guide clinical decisions regarding wound care and management and aid in the prediction of wound outcomes.
Burns and other skin injuries are growing concerns as well as challenges in an era of antimicrobial resistance. Novel treatment options to improve the prevention and eradication of infectious skin biofilm-producing pathogens, while enhancing wound healing, are urgently needed for the timely treatment of infection-prone injuries. Treatment of acute skin injuries requires tailoring of formulation to assure both proper skin retention and the appropriate release of incorporated antimicrobials. The challenge remains to formulate antimicrobials with low water solubility, which often requires carriers as the primary vehicle, followed by a secondary skin-friendly vehicle. We focused on widely used chlorhexidine formulated in the chitosan-infused nanocarriers, chitosomes, incorporated into chitosan hydrogel for improved treatment of skin injuries. To prove our hypothesis, lipid nanocarriers and chitosan-comprising nanocarriers (≈250 nm) with membrane-active antimicrobial chlorhexidine were optimized and incorporated into chitosan hydrogel. The biological and antibacterial effects of both vesicles and a vesicles-in-hydrogel system were evaluated. The chitosomes-in-chitosan hydrogel formulation demonstrated promising physical properties and were proven safe. Additionally, the chitosan-based systems, both chitosomes and chitosan hydrogel, showed an improved antimicrobial effect against S. aureus and S. epidermidis compared to the formulations without chitosan. The novel formulation could serve as a foundation for infection prevention and bacterial eradication in acute wounds.
Blood flow is a major regulator of hemostasis and arterial thrombosis. The current view is that low and intermediate flows occur in intact healthy vessels, whereas high shear levels (>2000 s-1) are reached in stenosed arteries, notably during thrombosis. To date, the shear rates occurring at the edge of a lesion in an otherwise healthy vessel are nevertheless unknown. The aim of this work was to measure the shear rates prevailing in wounds in a context relevant to hemostasis. Three models of vessel puncture and transection were developed and characterized for a study that was implemented in mice and humans. Doppler probe measurements supplemented by a computational model revealed that shear rates at the edge of a wound reached high values, with medians of 22 000 s-1, 25 000 s-1, and 7000 s-1 after puncture of the murine carotid artery, aorta, or saphenous vein, respectively. Similar shear levels were observed after transection of the mouse spermatic artery. These results were confirmed in a human venous puncture model, where shear rates in a catheter implanted in the cubital vein reached 2000 to 27 000 s-1. In all models, the high shear conditions were accompanied by elevated levels of elongational flow exceeding 1000 s-1. In the puncture model, the shear rates decreased steeply with increasing injury size. This phenomenon could be explained by the low hydrodynamic resistance of the injuries as compared with that of the downstream vessel network. These findings show that high shear rates (>3000 s-1) are relevant to hemostasis and not exclusive to arterial thrombosis.
Planning for management of bleeding in trauma injuries is very important. The initial purpose in emergency situations should be immediate establishment of an efficient hemostasis, principally in its topical application. In this study, we aimed to review the major relevant articles in the case of application of cellulose hemostatic agent on trauma injuries.
