LncRNA AGAP2-AS1 stabilizes ATG9A to promote autophagy in endothelial cells - Implications for burn wound healing

Deep second- or mixed-degree burn lesions are difficult to heal due to the impaired dermis supporting of epidermis renewal and nutrition delivery. Early dermis debridement and preservation speed healing and enhance results, emphasizing the need of knowing processes that promote burn-denatured dermis recovery, notably endothelial cell angiogenesis and autophagy. Integrative bioinformatics investigations identified AGAP2-AS1 as a highly elevated lncRNA in burn tissues. Pearson's correlation study connected AGAP2-AS1 to 112 differently co-expressed protein-coding genes involved in burn healing processes such cell cycle and TGF-beta receptor signaling. Experimental validation showed that heat damage elevated AGAP2-AS1 in HUVECs and HDMECs. Functionally, AGAP2-AS1 overexpression in heat-denatured HUVECs and HDMECs increased cell survival, migration, invasion, and angiogenesis. In addition, AGAP2-AS1 overexpression increased endothelial cell autophagy. Additional investigation showed AGAP2-AS1's association with ATG9A, stabilizing it. Post-heat damage, ATG9A knockdown drastically reduced HUVEC and HDMEC survival, migration, invasion, angiogenesis, and autophagy. More notably, ATG9A knockdown drastically reduced the benefits of AGAP2-AS1 overexpression on endothelial cell functions and autophagy. The positive association between AGAP2-AS1 and ATG9A expression in burn tissue samples highlights their crucial roles in endothelial cell response to heat injury, indicating that targeting this axis may aid burn wound healing. The research found that lncRNA AGAP2-AS1 stabilizes ATG9A and promotes autophagy in endothelial cells. These results imply that targeting the AGAP2-AS1/ATG9A axis may improve angiogenesis and tissue regeneration in burn injuries, revealing burn wound healing molecular pathways.

Necrotizing fasciitis: treatment concepts & clinical outcomes – an institutional experience

BackgroundA severe infection of the skin and soft tissues, Necrotizing Fasciitis (NF), spreads quickly along the deep fascia. This study aimed to characterize the clinicopathological features, analyze the implicated bacteria’s antibiotic sensitivity, evaluate surgical management, and assess the diagnostic accuracy of the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score in Necrotizing Soft Tissue Infection (NST).MethodsThis single-center prospective observational study was conducted in the Department of General Surgery, Kasturba Medical College, Manipal, with 171 proven cases of NSTI between 2019 and 2021. Clinico-demographic data and laboratory investigation values were collected at two-time points (at admission and 72 h after admission). Imaging data, LRINEC score, culture results, and antibiotic sensitivity were recorded. Appropriate descriptive and analytical statistics were used for the statistical analysis.ResultsOf the 171 patients, 150 were male (87.7%). The mean age was 57.6 ± 13.1 years. The presenting features in all the cases were pain, swelling, and fever. Diabetes mellitus (DM) is the most common comorbidity. The lower extremities were the most commonly affected sites. Streptococcus pyogenes showed significant growth in 25.41% of the samples. Ceftriaxone sensitivity was seen in 41/141. A score of ≥ 8 was obtained in 118/171 (69%) patients, suggesting a higher severity and significant risk for NSTI. The Area Under the Curve of Receiver Operating characteristic Curve (ROC) for establishing diagnostic accuracy for LRINEC was 0.694. Mortality was significantly higher in the patients with higher LRINEC scores and elevated procalcitonin. The mortality rate was higher in patients who underwent surgery within 12 h.ConclusionNecrotizing fasciitis is a soft tissue infection with a high mortality rate. The clinical features and determinants of mortality in patients with NF are highlighted in this study. At the outset, a high index of suspicion was critical. Using prognostic evaluation techniques in daily clinical practice will assist medical professionals in providing adequate on-time care and significantly lowering mortality. The AUC for LRINEC score, although significant, is low. LRINEC score is not to be used to determine whether surgical intervention should be expedited or anticipated. Its role is to aid in prognosticating the outcome of the individual patient. Our study concludes that early extensive surgical debridement remains the single most crucial intervention in patients diagnosed with necrotizing fasciitis (NF), regardless of disease severity and the LRINEC score.

Short-to-Mid-Term Outcomes of Ipsilateral Femoral Head Autograft Combined with Uncemented Total Hip Replacement for Partial Periacetabular Defects Following Tumor Resection.

Periacetabular tumors, especially in young to middle-aged patients with invasive benign tumors or low-grade malignant tumors involving type II or II + III, present significant challenges due to their rarity and the complexity of the anatomical and biomechanical structures involved. The primary difficulty lies in balancing the need to avoid unfavorable oncological outcomes while maintaining postoperative hip joint function during surgical resection. This study aimed to evaluate the effectiveness and reliability of a surgical method involving partial weight-bearing acetabular preservation combined with the use of an uncontaminated femoral head autograft to reconstruct the segmental bone defect after intra-articular resection of the tumorous joint, providing a solution that ensures both oncological safety and functional preservation of the hip joint in these patients. We conducted a retrospective study with a follow-up period of at least 36 months. From January 2010 to October 2020, we reviewed 20 cases of patients under 60 year of age with periacetabular invasive benign tumors or primary low-grade malignant tumors. All patients underwent reconstruction of the tumorous joint using autologous femoral head grafts. Data collected included patient age, gender, tumor type, preoperative and postoperative visual analog scale (VAS) scores, Musculoskeletal Tumor Society (MSTS) scores, Harris Hip Scores (HHS), patient survival rates, postoperative tumor recurrence, and surgical complications. To analyze the data, we utilized various statistical methods, including descriptive statistics to summarize patient demographics and clinical characteristics, and paired sample t-tests to compare preoperative and postoperative scores. The study included 20 patients, and a total median follow-up was 83 months. Their pathologic diagnoses comprised 13 giant cell tumors (GCTs), 5 chondrosarcomas, one chondroblastoma, and 1 leiomyosarcoma. Postoperatively, the median differences in vertical and horizontal center of rotation (COR) were 3.8 and 4.0 mm. Median limb length discrepancy (LLD) postoperatively was 5.7 mm (range, 2.3-17.8 mm). Two patients (10%) experienced delayed wound healing, resolved with antibiotics and early surgical debridement. One patient experienced dislocation 3 months postoperatively, which was promptly addressed under general anesthesia without further dislocation. Through multiplanar osteotomy with limited margins, femoral head autograft, and uncemented total hip replacement for pelvic segmental bone defects in selected patients in type II or II + III appears to be an encouraging limb-sparing surgery worthy of consideration for carefully selected patients.

Comparison of Early Versus Late Debridement Outcomes in the Management of Open Distal Radius Fractures

The optimal timing for surgical treatment of open distal radius fractures remains an area of debate. The purpose of this study was to examine the outcomes of open distal radius fractures treated surgically before or after 24 hours. A multicenter retrospective review was performed on all open distal radius fractures treated over 11 years. Patient demographics, injury mechanism, and initial treatment were recorded. Fracture severity was graded by the Gustilo-Anderson classification. Comparisons were made between those treated surgically within and after 24 hours. Outcomes examined included infection, revision surgery, osteomyelitis, and nonunion. A total of 230 cases met the inclusion criteria. The cohorts of early and delayed surgical intervention were similar with regard to preoperative demographics. The most common mechanism of injury was motor vehicle accident. Approximately 40% of cases were graded as type I, 40% as type II, and 20% as type III. Mean time to debridement in the group treated after 24 hours was 5 days. A mean postoperative follow-up of greater than 6 months was obtained in both cohorts. Similar outcomes were found between cohorts with respect to postoperative infection, revision surgery, osteomyelitis, and nonunion. Similar outcomes with regards to infection, revision, osteomyelitis, and nonunion were found between open distal radius fractures treated emergently versus those managed in a delayed fashion. Patient- and injury-specific factors are important in dictating care. Prognostic IIB.

Pediatric facial trauma management: Emergency case in a toddler

Background: Facial soft tissue trauma cases are often encountered in the emergency room. Soft tissue trauma, especially to the face, is rarely life threatening. It varies in shape, size, and depth and can also affect surrounding organs. The treatment of soft tissue trauma can be complicated and may have a significant impact on facial function and, especially, facial aesthetics. Children are easily injured due to their active nature. Soft tissue trauma to the faces of toddlers is challenging even for experienced surgeons; however, wound debridement and suture management under general anesthesia should be considered. Purpose: The aim of this article is to deliver a thorough overview of the evaluation and treatment of soft tissue injuries in children, covering initial assessments, physical examinations, the application of antimicrobial therapies, and preparation for surgical procedures. Case: An 11-month-old girl went to the emergency department of Hasan Sadikin General Hospital, Bandung, with injuries to her left cheek and upper left lip sustained when she fell, and her face hit the edge of a cement pot at home. There was no history of unconsciousness, nausea and vomiting. The injury was diagnosed as vulnus laceratum of the left face and upper lip region. Case management: Emergency management was carried out by triage, Tetagam injection, and early wound debridement and suture under general anesthesia because the patient was uncooperative. Wounds on the face and lips were primary sutured layer by layer, returning the wound edges to their normal anatomical position. Conclusion: The management of facial soft tissue injuries in toddlers requires general anesthesia for adequate and accurate wound debridement and suture, so that functional and aesthetic effects can be satisfactorily obtained.

Early arthroscopic debridement of posterior cruciate ligament calcification after symptom presentation led to immediate recovery: a case report

BackgroundWe report a rare case of posterior cruciate ligament (PCL) calcification, which has only been reported in two case studies on PubMed.Case presentationA 71-year-old man developed left popliteal pain in the morning without any history of trauma and the pain became severe that night. On the following day, he presented to our department. The patient could not flex his left knee at all due to pain and swelling. CT and MRI scans showed calcification behind the PCL with mild osteoarthritic changes and accumulation of synovial fluid in the joint. Synovial fluid analysis did not reveal any crystals. Blood tests at first admission showed inflammation, hyperglycemia, and low blood uric acid levels. Although the patient’s knee joint was injected with steroids, his symptoms did not improve. Thus, we performed arthroscopic surgery two days after symptoms had appeared. Intraoperatively, we observed a white, soft tissue in the synovial membrane behind the PCL. Part of this tissue was collected for histological analysis, which revealed sparse fibers with calcium deposits. Immediately after surgery, the patient’s symptoms were completely gone. Afterward, the patient remained asymptomatic one month after surgery.ConclusionThis is the first reported case of debridement of PCL calcification and ossification that was performed soon after symptoms appeared. In addition, we demonstrated that early debridement led to complete recovery.

Impact of Candidemia on Survival Rates in Major Burn Patients: A Retrospective Study from the South of Türkiye

Abstract Objective In severely burned patients, fungal infections are among the most devastating complications. Candidemia is an important cause of mortality with an increasing incidence despite advances in burn care management. Higher affected body surface area, long intensive care unit (ICU) stay, flame burn, third-degree burn, and previous bacterial infections were associated with the development of candidemia. Candidemia in patients with major burns admitted to an ICU of a tertiary burns center is investigated. Methods Patients hospitalized in the ICU of Adana City Training and Research Hospital from July 1, 2017, to November 10, 2020, were included. The demographic and clinical variables, the Candida species isolated from blood cultures and their antifungal susceptibilities, need for grafting, complications, and rate of mortality are evaluated retrospectively. Patients were grouped as “candidemia” or “noncandidemia” according to whether or not they experienced Candida bloodstream infection. Results A total of 371 patients were included; the mean age was 22.02 ± 20.9 years. Most patients were male (69.5%). The percentage of burned surface area was 25.93 ± 17.6. The mean ICU stay was 16.95 ± 16.3 days. There were 90 candidemia episodes in 69 patients. The most commonly isolated Candida species were C. parapsilosis, C. tropicalis, and C. albicans. The mortality rates in the candidemia and noncandidemia groups were 24.6 and 5.6%, respectively (p < 0.001). Conclusion Adhering to isolation rules, early wound debridement and closure, avoidance of catheters where possible, and avoidance of the early use of broad-spectrum antibiotics are important measures in reducing candidemia in patients with major burns. Candidemia was associated with greater burn surface areas, duration of hospital stay, and larger numbers of interventional procedures. However, previous bacterial infection receiving prolonged antibiotic therapy was the greatest risk factor of candidemia. Culture results are important to select the antifungal agent with high susceptibility, but results are not rapidly available. There is need for early clinical prediction measures to inform early and effective antifungal treatment.

Escalating Surgical Treatment for Left Ventricular Assist Device Infection and Expected Mortality: Clinical Risk Prediction Score.

Left ventricular assist devices (LVAD) improve survival for patients with cardiac failure, but LVAD-specific infection (VSI) remains a challenge with poorly understood predictive risk factors. The indications and use of escalating medical treatment to surgical debridement and potential flap reconstruction are not well characterized. A retrospective review of consecutive patients undergoing primary LVAD implantation at a tertiary academic center was performed. The primary outcome measures were 90-day and overall mortality after VSI. Cox proportional hazards regression was used to generate a risk prediction score for mortality. Of the 760 patients undergoing primary LVAD implantation, 255 (34%) developed VSI; of these patients, 91 (36%) were managed medically, 134 (52%) with surgical debridement, and 30 (12%) with surgical debridement and flap reconstruction. One-year survival after infection was 85% with median survival of 2.40 years. Factors independently associated with increased mortality were diabetes (hazard ratio [HR] 1.44, p = 0.04), MRSA infection (HR 1.64, p = 0.03), deep space (pump pocket or outflow cannula) involvement (HR 2.26, p < 0.001), and extracorporeal membrane oxygenation after LVAD (HR 2.52, p < 0.01). Factors independently associated with decreased mortality were flap reconstruction (HR 0.49, p = 0.02) and methicillin-sensitive Staphylococcus aureus infection (HR 0.63, p = 0.03). A clinical risk prediction score was developed using these factors and showed significant differences in median survival, which was 5.67 years for low-risk (score 0 to 1), 3.62 years for intermediate-risk (score 2), and 1.48 years for high-risk (score ≥3; p < 0.001) patients. We developed a clinical risk prediction score to stratify patients with VSI. In selected cases, escalating surgical treatment was associated with increased survival. Future work is needed to determine whether early surgical debridement and flap reconstruction can alter outcomes in select cases of VSI.

CLINICAL COMPLICATIONS OF MALIGNANT OTITIS EXTERNA AND SURGICAL TREATMENT

For clinical complications of malignant otitis externa and its surgical treatment, the introduction addresses a rare and serious condition, characterized by necrotizing infection of the external auditory canal, often associated with comorbidities such as decompensated diabetes mellitus. This condition requires rapid intervention due to the potential for spread to adjacent structures such as the skull and skull base, resulting in serious complications such as facial paralysis, osteomyelitis, and meningitis. Management includes broad-spectrum intravenous antibiotic therapy and, in many cases, surgical intervention to debride necrotic tissue and control infection. Objective: to synthesize recent evidence on the effectiveness of surgical treatments in malignant otitis externa, highlighting clinical outcomes and associated mortality. Methodology: it was structured according to the PRISMA checklist, using PubMed, Scielo and Web of Science databases to search for articles published in the last 10 years. Descriptors included "malignant otitis externa", "surgical treatment", "complications", "mortality" and "intervention". Inclusion criteria were clinical studies and systematic reviews that addressed surgical treatment and clinical outcomes. Exclusion criteria were studies focusing exclusively on non-surgical treatments, isolated case reports and studies with fewer than 10 participants. Results: highlighted the effectiveness of early surgical debridement in reducing mortality and serious neurological complications. The analysis revealed that adjuvant antibiotic therapy and intensive surveillance are crucial for successful management. Conclusion: the importance of a multidisciplinary approach and timely surgical intervention is emphasized to improve outcomes in patients with malignant otitis externa, highlighting the need for further studies to elucidate ideal therapeutic protocols and prevention strategies

The Different Surgical Approaches to Maxillofacial Reconstruction after Ballistic Trauma.

Ballistic trauma to the face is a challenge, combining complex bone injury with severe soft tissue loss. The various surgical methods available are influenced by the extent of injuries. This study compares different operative modalities and their outcomes with different variables, aiming to define the ideal therapeutic approach. We retrospectively compared reconstructive modalities used to treat facial ballistic trauma cases at Hôtel-Dieu de France Hospital, Beirut, Lebanon, for a 12-year span. Statistical analysis was used to determine correlation between several factors and satisfactory results. Eighteen patients were included, with varying degrees of bone and soft tissue loss. After conservative debridement, fractures were treated by different modalities: open reduction and internal fixation, maxillomandibular fixation, and osteosynthesis with a reconstruction plate. Although primary closure was sufficient in 10 cases, severe loss of tissues was reconstructed with a fibular free flap in five cases, radial free forearm flap in two cases, and free parascapular flap in one case. Two others received an iliac bone graft as secondary reconstruction. The average follow-up was 2.45 years. Most cases achieved good aesthetic and functional results after several secondary operations, with few late complications. Early reconstruction and younger patients were associated with better outcomes. We favor early debridement and reconstruction. Free flaps were ideal for extensive tissue loss. Bone grafting was needed secondarily. A single surgical procedure seldom led to satisfactory functional and aesthetic outcomes, and secondary operations were inevitable.

Is Prompt Hyperbaric Oxygen Adjunctive Therapy Able to Reduce Mortality and Amputation in Management of Necrotizing Soft-Tissue Infection?

Background: Necrotizing soft-tissue infection (NSTI) is a rare and serious disease with high morbidity and mortality. Standard therapeutic concepts have included urgent surgical intervention, broad-spectrum antibiotic treatment, and intensive care. Hyperbaric oxygen therapy (HBOT) is used as adjuvant therapy in some centers, but its benefits remain controversial. Methods: A retrospective analysis was conducted in which 98 patients with a clinical diagnosis of NSTI were treated with standard treatments plus HBOT. The clinical outcomes were wound healing, performance status, hospital length, complication rate, recurrence rate, morbidity (amputation rate), and mortality. Primary or secondary outcomes were compared between the time interval of HBOT and the clinical outcomes. Results: The average times from diagnosis of NSTI to initial HBO treatment and from initial surgery to initial HBO treatment were both significantly longer in dead patients than in surviving patients (P = 0.031; P = 0.020). These two time intervals were both significantly longer in amputated patients than in preserved patients (P = 0.031; P = 0.037). Conclusions: Using combined treatment with early surgical debridement combined with HBOT, it is possible to reduce hospital stay, intensive care unit stay, number of debridements, improve complete wound healing rate, and lower amputation and mortality rates among patients with NSTI. The early onset of HBOT soon after diagnosis, especially during critical conditions, is proved to be associated with higher survival and preservation rates.

Fournier's Gangrene Surgical Reconstruction: A Systematic Review.

Fournier's gangrene (FG) is a rare form of necrotizing fasciitis of the perineal, genital, or perianal region. It is characterized by an aggressive course and high mortality rate, over 20%. FG demands immediate treatment including resuscitation maneuvers, intravenous antibiotic therapy and early surgical debridement. Background/Objectives: The gold-standard treatment for FG is surgical reconstruction. However, up to date, no precise guidelines exist. Thus, we decided to systematically review the literature, focusing on FG contemporary approaches to reconstructive surgery, aiming to analyze the various reconstructive strategies and their specific indications. Methods: A systematic review was carried out according to the PRISMA statement by searching various databases from April 2014 to April 2024, using the terms ''Fournier Gangrene OR Fournier Gangrene Reconstruction OR Fournier Gangrene Treatment OR Fournier Gangrene Plastic Surgery OR Necrotizing Fasciitis OR Necrotizing Fasciitis AND Reconstruction". The eligibility criteria included original studies aimed at discussing FG reconstruction with at least three clinical cases. Results: The final synthesis included 38 articles, and 576 reconstructions were described. Of these, 77.6% were minimally invasive strategies (direct closure, secondary healing, grafts, and local random flaps), while more invasive reconstructions (loco-regional flaps based on known vascular anatomy) were adopted in 22.4%. No free flaps were reported. Conclusions: FG requires immediate medical interventions including broad-spectrum antibiotic therapy, surgical debridement, adjuvant therapies, and reconstructive surgeries. Taking into account the anatomical characteristics of the inguinal-crural region, skin grafts and local random flaps could offer versatile and effective reconstructions for most FG cases, while the more invasive strategies should be reserved for very few cases. Future research is warranted to define an FG dedicated reconstruction protocol.

Necrotising fasciitis of the upper limb: a review of the literature.

Necrotising fasciitis is an uncommon life-threatening surgical emergency. While most commonly seen in the lower limb it can also affect the upper limb. This article reviews and summarises the current literature on necrotising fasciitis in the upper limb, covering common predisposing factors, clinical presentations, scoring systems, common organism types and the timing of surgical treatment. The key to managing this condition continues to be early clinical diagnosis and aggressive surgical debridement to attempt to reduce the morbidity and mortality of this condition.

Outcomes of early versus late irrigation and debridement of pediatric open long bone fractures.

Open long bone fractures are a major concern for pediatric patients due to the risk of surgical site infection (SSI). Early studies have recommended irrigation and debridement of open fractures within 6 hours-8 hours for the prevention of SSI. According to the American College of Surgeons (ACS) Best Practice Guidelines, in 2015, irrigation and debridement should be done within 24 hours. To identify whether early irrigation and debridement, within 8 hours, vs late, between 8 hours and 24 hours, for pediatric open long bone fractures impacts rate of SSI. Using retrospective data review from the National Trauma Data Bank, Trauma Quality Improvement Project (TQIP) of 2019. TQIP database is own by the ACS and it is the largest database for trauma quality program in the world. Propensity matching analysis was performed for the study. There were 390 pediatric patients with open long bone fractures who were included in the study. After completing propensity score matching, we had 176 patients in each category, irrigation and debridement within 8 hours and irrigation and debridement between 8 hours and 24 hours. We found no significant differences between each group for the rate of deep SSI which was 0.6% for patients who received surgical irrigation and debridement within 8 hours and 1.1% for those who received it after 8 hours [adjusted odd ratio (AOR): 0.5, 95%CI: 0.268-30.909, P > 0.99]. For the secondary outcomes studied, in terms of length of hospital stay, patients who received irrigation and debridement within 8 hours stayed for an average of 3.5 days, and those who received it after 8 hours stayed for an average of 3 days, with no significant difference found, and there were also no significant differences found between the discharge dispositions of the patients. Our findings support the recommendation for managing open long bone fractures from the ACS: Complete surgical irrigation and debridement within 24 hours.

Acute and post-acute soft tissue reconstruction

The precise analysis of the injured structures requiring reconstruction in complex wound defects is aprerequisite for successful restoration. The fundamental reconstructive strategies for soft tissue defects of the extremities including injuries to vessels, nerves and burn wounds in the context of the acute and post-acute trauma phases are presented. The different phases of soft tissue reconstruction are described. Recommendations for action with respect to the reconstruction of the functional structures are described. Two clinical case examples illustrate the approach. The acute reconstruction phase is defined as the period 0-72 h after the traumatic event and includes surgical debridement, primary reconstruction of nerves and vessels using interpositional grafts if necessary and temporary soft tissue reconstruction. Combined thermomechanical trauma requires early debridement combined with internal fixation of open fractures. In the post-acute reconstruction phase, which is generally defined as aperiod of up to 6weeks after the traumatic event, definitive soft tissue reconstruction is performed. In the case of long reinnervation distances, nerve transfer or motor replacement plastic surgery is performed in the post-acute phase. The reconstruction of soft tissue after trauma necessitates a stage-dependent approach. In the acute phase procedures aim at the immediate preservation of the limb. In the post-acute phase, definitive soft tissue reconstruction is performed to enable maximum functional preservation. Combined thermomechanical injuries require early surgical treatment in order to prevent infections.

NECROTIZING FACICIT AFTER HEMOROIDECTOMY

Necrotizing fasciitis (NF); is a progressive soft tissue infection involving the lower extremities and perianal region, extending from the skin to the fascia. Although it is frequently seen in the elderly, it can be seen in all age groups with concomitant diseases, previous surgery history, and immune system disorders. NF, which develops as a result of rapid tissue invasion, can cause serious morbidity and mortality if early diagnosis and early surgical debridement are not performed. Therefore, NF should be suspected if pain, fever, and septic markers are disproportionate to the lesion in the clinic. The most important step in the treatment of NF is early surgical debridement and initiation of appropriate antibiotics. In addition to these treatments, various wound care treatments can also be applied. We tried to explain the process from diagnosis to discharge in a patient who developed NF after hemorrhoidectomy in terms of treatment management.

Antibiotic bone cement covered reconstruction plate for infected anterior pelvic ring fractures

To explore the clinical efficacy of antibiotic bone cement covered reconstruction steel plate in the treatment of infected anterior pelvic ring fracture. From January 2017 to March 2022, 11 patients with infected anterior pelvic ring fracture were treated with antibiotic bone cement covered reconstruction steel plate including 7 males and 4 females and the age ranged from 27 to 49 years old. The pelvic fractures were classified according to the Tile typology: 4 cases of C1 type, 4 cases of C2 type, and 3 cases of C3 type. Among them, 2 cases of infected anterior ring were infected after internal fixation of anterior ring, and 9 patients were infected with infected anterior ring due to incomplete early debridement, which was classified as infected according to the injury severity score(ISS) for 24 to 38 scores. The anterior ring was internally fixed by extended debridement, irrigation, and antibiotic bone cement covered reconstruction plate, and the posterior ring fractures were all closed reduction and internally fixed with sacroiliac screws. All 11 cases obtained follow-up from 13 to 20 months. Among them, 2 patients had recurrence of postoperative infection, 1 case was re-dissected and replaced with antibiotic bone cement-coated internal fixation, and 1 case had a milder infection without accumulation of the medullary cavity, and the infection was controlled by retaining the plate and replacing the antibiotic bone cement only after dissecting. Two cases developed incisional oozing, which healed after removal of the internal fixation three months postoperatively. All patients did not show pelvic fracture redisplacement or reinfection during the follow-up period. All 11 cases eventually healed bony. At the final follow-up, according to the Matta score, the fracture reduction was excellent in 6 cases, good in 4, and possible in 1. According to the Majeed functional score, it was excellent in 6, good in 3, and possible in 2. Antibiotic bone cement covered reconstruction plate is effective in the treatment of infected anterior pelvic ring fracture, with high intraoperative safety and low recurrence rate of infection, which is conducive to the early postoperative rehabilitation and significantly shortens the course of the disease.

Current diagnosis and management of necrotizing soft tissue infections: What you need to know.

Necrotizing soft tissue infections are rare bacterial infections of the skin and soft tissues with a high morbidity and mortality rate, requiring prompt diagnosis and surgical intervention. These represent a spectrum of disease resulting in tissue necrosis that is rapidly progressive; however, they remain a diagnostic challenge because the average surgeon or emergency medicine provider may only see one or two over the course of their career. Diagnosis is largely clinical and based on subtle physical examination findings, physiologic instability, and laboratory derangements. Aids to diagnosis such as scoring systems and cross-sectional imaging may be used; however, the findings are not specific, so management should not be based on these alone. The most common cause of necrotizing soft tissue infection is polymicrobial infection; however, specific bacteria such as clostridial species, group A streptococcal, methicillin resistant Staphylococcus aureus , and aquatic bacteria may also be causative. Initial management includes broad spectrum antibiotics, fluid resuscitation for severe sepsis, and early aggressive surgical debridement. Often, these patients require multiple operative debridement to achieve source control, and a low threshold for repeat debridement should be maintained because these infections can progress rapidly. Once source control is achieved, patients may be left with extensive wounds requiring multidisciplinary care and wound management. Necrotizing infections have long been viewed based on mortality outcomes alone because of their rarity and severity. Over recent years, more reports have shown a decrease in the mortality rates from those previously reported, allowing for a focus on methods to improve morbidity of these infections.

DO ORTHOPAEDIC TRAUMA SOCIETY (OTS) SIMPLE FRACTURES RECEIVE A DIFFERENT STANDARD OF TREATMENT TO OTS COMPLEX FRACTURES?

IntroductionOpen fractures of the tibia are disabling injuries with a significant risk of deep infection. Treatment involves early antibiotic administration, early and aggressive surgical debridement, and may require complex soft tissue coverage techniques. The extent of disruption to the skin and soft-tissue envelope often varies, with ‘simple’ open fractures (defined by the Orthopaedic Trauma Society (OTS) open fracture severity classification) able to be closed primarily, whilst others may require shortening or soft-tissue reconstruction. This study aimed to determine whether OTS simple tibial open fractures received different rates of adequate debridement and plastic surgical presence at initial debridement, compared with OTS complex injuries, and whether rates of fracture-related infection, nonunion, or reoperation differed between the groups.Materials &amp; MethodsA consecutive series of open tibia fractures managed at a tertiary UK Major Trauma Centre between January 2021 and November 2022 were included. Patient demographics, injury characteristics, timing of antibiotic delivery, timing and method of definitive fixation, and frequency of plastic surgical presence at initial debridement were retrospectively collected. The delivery of bone ends at initial debridement was used as a proxy for adequacy of surgical debridement. The primary outcome measure was rate of fracture-related infection, secondary outcomes included rates of reoperation, nonunion, and amputation. Chi2 Tests and independent samples T-tests were used to assess nominal and continuous outcomes respectively between simple and complex injuries. Ordinal data was assessed using nonparametric equivalent tests.Results79 patients with open fractures of the tibia were included. 70.8% of patients were male, with mean age 50.4 years (SD 19.2) and BMI 26.4 Kg/m2 (SD 6.0). Injuries were mostly sustained by low-energy falls (n = 28, 35.4%) and from road traffic accidents (n = 26, 32.9%). 27 (34.2%) were OTS simple open fractures. Simple open fractures were most commonly Gustillo-Anderson grade 1 (38.5%), or 2 (30.8%), whilst complex open fractures were mostly grade 3B (66.7%) (p &lt; 0.001). Fracture-related infection rates in OTS simple and complex open fractures were 25.9% and 25.5% respectively (p = 0.967), and nonunion rates were 32% and 37.8% (p = 0.637). Primary amputation was less common in simple (0%) than in complex open fractures (20%, p = 0.012), there were no differences in delayed amputation rates (7.4% and 6% respectively, p = 0.811). Simple open fractures were less likely to have plastic surgeons present at initial debridement compared to complex open fractures (18.5% and 44%, p = 0.025), and less likely to have bone ends delivered through the skin at initial debridement (25.9% and 61.2%, p = 0.003). There were no differences in patient age, delays to antibiotic administration, or reoperation rates between OTS simple and OTS complex fractures (p &gt; 0.05).ConclusionsDespite involving less significant soft tissue injury, OTS simple open tibia fractures had comparable deep infection and nonunion rates to complex fractures and received early plastic surgical input and adequate debridement less frequently. The severity of open fractures with less significant soft tissue injury may be underrecognized and therefore undertreated, although further prospective study is needed.

Effects of early debridement and conservative eschar removal followed by wound coverage with acellular dermal matrix in the treatment of children with deep burns

Effects of early debridement and conservative eschar removal followed by wound coverage with acellular dermal matrix in the treatment of children with deep burns
