Current Concepts in Diagnosis and Management of Hand Infections.

Hand and upper-extremity infections span a broad spectrum of presentations for the hand surgeon, primary care provider, and emergency medicine practitioner. As many hand infections arise from penetrating trauma, knowledge of the offending pathogen, location, and mode of spread allows the clinician to determine the appropriate intervention. Along with a thorough history and physical examination, patient factors such as age, occupation, medical comorbidities, and surgical history should be noted. Timely diagnosis and appropriate management allow for optimal recovery and outcomes. In this article, we describe the ongoing debate regarding the timing and influence of preoperative antibiotics on culture yield, timing of debridement for open fractures as it relates to infection risk, and strategies for obtaining adequate cultures to guide antibiotic therapy for complex infections such as periprosthetic joint and hardware infections. Given the changing epidemiological landscape and increased rates of antibiotic resistance, it is critical to promote antibiotic stewardship. We provide updated treatment recommendations and antibiotic profiles for the treatment of common hand infections. Finally, we discuss newer technologies such as next-generation sequencing and development of promising diagnostic and treatment strategies that will enhance the hand surgeon's ability to treat complex hand infections.

CONSENSUS ON THE APPLICATION AND CARE OF BROMELAIN-BASED ENZYMATIC DEBRIDEMENT ON BURNS.

Treatment of burned patients involves early excision of the burn. The approach to this excision has changed since bromelain-based enzymatic debridement was introduced. This treatment option reduces complications from the surgical procedure and improves scar quality. It is indicated for partial and full thickness burns. It is important to agree on the nursing care before, during and after enzymatic debridement treatment to ensure an optimal preparation and maintenance of the wound bed for later treatment to be most successful. A multi-centre Delphi study was conducted with enzymatic debridement nursing care on burned patient experts. A coordinating group developed a 29-item questionnaire based on clinical guidelines and experience. Two question rounds were asked, reaching consensus on answers > 70%. Nine panellists from nine leading burns centres in Spain participated. The aim was to develop a national consensus on enzymatic debridement treatment based on clinical practice and evidence from almost 1500 cases. The experts reached 29 agreements on different aspects of treatment and patient condition: general considerations about the treatment, burned patient admission, treatment prior to enzymatic debridement, applying debridement, removing enzymatic debridement and the post-enzymatic debridement phase. The expert consensus on nursing care of the burn patient and application of bromelain-based enzymatic debridement includes general recommendations for the patient before, during and after application and the planning of localised care after debridement. This consensus document supports knowledge on enzymatic debridement technique, increasing safety in clinical nursing practice and ensuring successful treatment for the patient.

L'excision précoce est la référence dans le traitement des brûlures. Sa technique a été transformée par le débridement enzymatique à la bromélaïne. Cette technique, indiquée dans les brûlures intermédiaires et profondes, réduit les complications chirurgicales et améliore la qualité cicatricielle. La qualité des soins locaux, avant, pendant et après l'application de bromélaïne, est un paramètre important d'efficacité. Nous avons organisé une étude basée sur la méthode Delphi auprès de 9 experts de 9 CTB espagnols. Le groupe de coordination a réalisé un questionnaire à 29 items à partir des recommandations et de leur expérience (quasiment 1 500 cas au total). Deux séances ont été organisées, dans le but d'obtenir les agréments de plus de 70% des participants. Un consensus a été obtenu sur les 29 questions posées, se rapportant aux généralités, aux critères d'admission, au traitement avant bromélaïne, à son application, à son retrait et aux soins ultérieurs. Les recommandations de soins locaux consécutives recouvrent les phases avant, pendant et après utilisation. Elles permettent une amélioration de l'efficacité et de la sécurité du débridement enzymatique.

Higher Morbidity and Mortality in Females With Fournier's Gangrene Compared to Males: Insights From National Inpatient Sample Data.

PURPOSE: To compare Fournier's gangrene in female and male patients, and identify mortality-associated characteristics in both. MATERIALS AND METHODS: We employed National Inpatient Sample data (2016-2020) to identify Fournier's gangrene cases and extracted demographic, comorbidity, and procedural variables. Multivariable regression models were utilized to identify mortality risk factors for both cohorts. RESULTS: We identified 2875 females (31%) and 6451 males (69%) with Fournier's gangrene corresponding to an estimated 14,375 (95% CI 13,784-14,966) and 32,255 (95% CI 31,390-33,120) cases, respectively. Females were more likely to die than males (7.1% vs 5.7%, P < .0001, respectively). Median incidence rates were 1.7 (IQR 1.5-1.8) and 4 (IQR 3.6-4.3) cases per 100,000 person-years for females and males, respectively. Females had higher median age, longer hospital stays, more charges, procedures, and fecal diversion rates, but lower routine discharges than males (P < .05). Non-White females had increased mortality odds compared to White females (odds ratio [OR] 1.49, 95% CI 1.07-2.07, P = .019). Prolonged interval until initial perineal debridement correlated with higher mortality odds in both females and males (OR 1.02, 95% CI 1-1.04, P = .034 vs OR 1.03, 95% CI 1.01-1.05, P < .0001). Diabetes lowered mortality odds in females and males (OR 0.68, 95% CI 0.47-0.99, P = .046 vs OR 0.54, 95% CI 0.41-0.7, P < .0001). CONCLUSIONS: In females, Fournier's gangrene incidence surpasses previous reports, with slightly worse outcomes compared to males, emphasizing the need for precise clinical assessment and early intensive interventions.

Comparison of Clinical Outcomes of Posterior-Only Transforaminal Debridement and Interbody Fusion With Preservation of Posterior Ligamentous Complex Versus Conventional Posterior-Only Debridement and Interbody Fusion for Thoracic Spine Tuberculosis: A Prospective, Randomized, Controlled, Clinical Trial - A Pilot Study.

OBJECTIVE: The main objective of this study was to analyze the efficacy and feasibility of surgical management for patients with thoracic spinal tuberculous spondylitis (STB) by using posterior-only transforaminal debridement and interbody fusion (PTDIF) with preservation of posterior ligamentous complex (PLC) and noninferior of PTDIF compared with conventional posterior-only debridement and interbody fusion (CPDIF). METHODS: From January 2019 to January 2022, a prospective, randomized, controlled trial was conducted in which patients with thoracic STB were enrolled and assigned to undergo either the PTDIF group (group A) or CPDIF group (group B) in a 1:1 ratio. The clinical efficacy was evaluated on average operation time, blood loss, hospitalization durations, visual analogue scale, Oswestry Disability Index scores, erythrocyte sedimentation rate (ESR), C-Reactive protein (CRP), and neurological function recovery using the American Spinal Injury Association's impairment scale and operative complications. Radiological measurements included kyphosis correction, loss of correction. The outcomes were compared between the groups at preoperation, postoperaion, and final follow-up. RESULTS: All 65 patients were completely cured during the follow-up. The intraoperative blood loss and operation time in group B were more than that in group A. All patients were pain-free at the final follow-up visit. ESR, CRP returned to normal limits in all patients 3 months after surgery. All patients had improved neurological signs. No significant difference was found in kyphosis angle correction, loss of correction between the 2 groups. CONCLUSION: PTDIF, with preservation of PLC, achieved debridement, decompression, and reconstruction of the spine's stability, similar to CPDIF in the surgical treatment of thoracic STB. PTDIF has less surgical trauma with less intraoperative blood loss and operation time.

Do Post-debridement Cultures have a Role in Reduction of Infection in Open Fractures? Report of 166 Cases and Literature Review.

Objective: To evaluate the role of post-debridement cultures in the prevention of future infection following open fractures. Design: Retrospective Cohort Study and Literature Review. Setting: Division of Orthopaedic Surgery, Sultan Qaboos University Hospital, Academic and tertiary health care, Muscat, Oman. Participants: A total of 166 patients from a cohort study and 539 patients from the literature review with open fractures. There were 640 cumulative patients fit the inclusion and exclusion criteria. Intervention: Using predetermined inclusion and exclusion criteria, data on all open fractures were gathered from the electronic health system of a single institution between 2010 and 2019. PubMed and Embase electronic databases were also searched for relevant articles relating to post-surgical debridement culture and its correlation with future infection. Main outcome measures: Assessing the benefit, role of post-debridement cultures in the prevention of future infection following open fractures. Results: Combining the results of this retrospective cohort study and previously published data, there were 640 Gustilo-Anderson grades II and III open fractures which had post-debridement screening. Eighty-eight patients (13.8%) developed an infection, out of which 16 had positive post- debridement cultures (18.2%). Only four grew similar organisms at screening and infection stages, two of which had different antibiotic resistance patterns at the infection stage. Seventy-two fractures had negative post-debridement screening swabs (81.8%). Of the 59 (9.2%) fractures with positive screening only four (6.8% of the infected fractures) developed later deep infection. All these 59 cases had culture-guided antibiotic treatment, with or without surgical debridement. Conclusion: Although the bacterial growth of post-debridement cultures is low, post-debridement screening as part of a comprehensive management protocol may have a role in reducing deep infection in open fractures. This is particularly the case in Gustilo and Anderson type 3 open fractures, the risk of infection is high. The poor association between organisms isolated from screening and those from subsequent deep infection may mean that the later infective organisms have been acquired from a secondary colonisation source after the debridement. Level of evidence: III. How to cite this article: Kindi NA, Abri FA, Yaseen A, et al. Do Post-debridement Cultures have a Role in Reduction of Infection in Open Fractures?

Meleney's Gangrene of the Abdomen Managed With Serial Debridement and Negative Pressure Wound Therapy: A Case Report.

Meleney's gangrene (necrotizing fasciitis (NF)), also known as progressive bacterial synergistic gangrene, is a potentially fatal subcutaneous tissue infection with abdominal wall necrosis that progresses rapidly and systematically. It has been observed to exhibit the cultural characteristics of a symbiotic organism. Due to its rarity and high mortality rate, this infection needs to be diagnosed promptly and treated aggressively with antibiotics and rigorous debridement. There are several approaches to management, which include intravenous antibiotics, aggressive debridement, and dressings, along with the application of negative pressure wound therapy (NPWT). Herein, we report the case of a 45-year-old male patient with type 2 diabetes mellitus who presented to our facility after being bitten by an insect and exhibiting symptoms of Meleney's gangrene of the abdomen.

Modular component exchange has no advantage in Debridement, Antibiotics and Implant Retention (DAIR) for early onset hip and knee prosthetic joint infection.

INTRODUCTION: Debridement, Antibiotics and Implant Retention (DAIR) has been the mainstay of treatment for early onset periprosthetic joint infection in spite of variable results. Modular component exchange is a widely recommended strategy to improve success rates with DAIR though very strong evidence to support its practice is still lacking. MATERIALS AND METHODS: Eighty six patients underwent DAIR for early onset PJI following primary hip and knee arthroplasty were divided into two groups for this retrospective review. 45 patients (group 1) underwent DAIR with modular component exchange and 41 patients without exchange (group 2). We compared success rates based on infection eradication (primary outcome variable) and need for revision surgical procedures between these two groups. We also assessed differences in primary outcome based on type of arthroplasty, timing of DAIR and addition of local antibiotics. RESULTS: The overall success rate after DAIR was 71%. The outcome was similar in both groups (69% vs 74%, P = 0.66). The need for revision surgical procedures was 27% which was similar in both groups (P = 0.98) with 23% needing revision of prosthetic components. Type of arthroplasty (hip or knee) and addition of local antibiotics had no bearing on infection eradication after DAIR with or without modular component exchange. DAIR with in 45 days of primary arthroplasty had significantly higher success rate compared to DAIR after 45 days in both groups. CONCLUSIONS: We observed that modular component exchange did not improve infection eradication after DAIR for early onset PJI following hip and knee arthroplasty. Reasonable success rates can be expected after DAIR especially if the patient develops early clinical signs and the procedure is carried out as early as possible.

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

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IIB.

The adjunctive use of Leukocyte-Platelet Rich Fibrin (L-PRF) in the management of Medication Related Osteonecrosis of the Jaw (MRONJ): a retrospective observational study.

PURPOSE: Medication related osteonecrosis of the jaw (MRONJ) is a risk for patients taking anti-resorptive or anti-angiogenic medications. The American Association of Oral and Maxillofacial Surgeons (AAMOS) has classified MRONJ in stages to reflect the severity of the disease and allows implementation of suitable treatment pathways. MRONJ risk is < 5% in cancer patients and < 0.05% in osteoporosis patients. Management is subdivided into operative and non-operative, with advances in the literature investigating adjuvants. Leukocyte-Platelet Rich Fibrin (L-PRF) is an autologous biomaterial consisting of leukocytes and platelets embedded within a fibrin matrix with the ability to release growth factors enabling angiogenesis, bone regeneration and soft tissue healing. This paper's aim is to investigate the effects of L-PRF in conjuction with surgical debridement for management of MRONJ. METHODS: Twenty-two cases with established MRONJ were treated with either surgical intervention (Group A) or with surgical intervention and L-PRF (Group B), from 2016 to 2023 at Edinburgh Dental Institute (EDI). Treatments were deemed successful when the patients were asymptomatic, displayed complete soft tissue healing with the absence of infection/inflammation, fistula, or exposed bone. RESULTS: All cases in Group B had healed in contrast to 54.5% not healed in Group A; p value < 0.05 indicating statistical significance. CONCLUSION: The use of L-PRF as an adjuvant to surgical management of MRONJ is promising with its favourable functional capacity, simple application, and success of treatment outcomes.

Outcome of Fournier's gangrene in relation to Fournier Gangrene Severity Index (FGSI) score.

Introduction: Fournier's gangrene is a rapidly progressive necrotizing fasciitis, involving perineum mainly. The purpose of the study is to evaluate etiology, treatment, and outcome of Fournier's gangrene so that such type patient's management can be done by primary care physicians with best outcomes. Method: This was a retrospective study including 156 patients, treated for Fournier's gangrene, between Jan 2012 and Dec 2018. The outcome and prognosis of Fournier's gangrene were reviewed. Result: The mean age and mode among survival patients were 47.94 ± 14.9 and 60 years, and the mean age and mode in nonsurvival patients was 47.64 ± 15.9 and 65 years. The most common predisposing factor was diabetes mellitus (n = 49, 31.4%) having mortality rate was 9% (n = 14). Most common causative bacteria were E. coli. In the study, the survival rate was 100% in patients having Fournier Gangrene Severity Index (FGSI)≤3. As FGSI increased from 3, the mortality rate increased. Conclusion: Fournier gangrene is a surgical emergency. Early diagnosis, serial surgical debridement, and broad-spectrum antibiotics decrease the mortality and morbidity of patients. The sensitivity and specificity of FGSI determine the prognosis of Fournier's gangrene. FGSI is a simple method to know the severity and prognosis.

Revision of the Wolford protocol for managing infections in temporomandibular joint prostheses: an updated surgical approach.

The management of infected temporomandibular joint prostheses presents a surgical challenge. In certain instances, an intermediate approach involving biofilm debridement and local antibiotic instillation may obviate the need for prosthesis removal. This technical note describes an update of the technique outlined by Wolford for managing infections, in which improved materials are used to implement the technique.

Bromelain-Based Enzymatic Debridement Versus Standard of Care in Deep Burn Injuries: A Systematic Review and Meta-Analysis.

Deep burn injuries necessitate effective debridement to promote healing and reduce complications. Traditional surgical debridement is the standard of care; however, it can lead to significant tissue loss, excessive bleeding and delayed healing. Bromelain-based enzymatic debridement offers a potential less invasive alternative that aims to selectively remove necrotic tissue while preserving viable ones. Therefore, this systematic review and meta-analysis comprehensively compares bromelain debridement versus standard care in the management of partial and full-thickness burns. Cochrane Library, Embase, and Medline were searched until May 30th, 2024 for studies comparing bromelain debridement versus standard care. R version 4.4.0 was used to pooled risk ratio and mean difference in a random-effects model. We included seven studies, comprising 484 participants, of whom 238 (49%) were treated with enzymatic debridement. Bromelain significantly reduced time to eschar removal (MD - 7.60 days 95% CI [-9.76, -5.44]; I² = 70%) in comparison with standard care. Additionally, bromelain group presented a significant reduction in the risk of surgical excision (RR 0.17; 95% CI [0.06, 0.47]; I² = 79%) and need for autografts (RR 0.40; 95% CI [0.18, 0.93]; I² = 76%) in comparison with standard group. No differences were found in behalf of time to wound closure (MD -7.64; 95% CI [-18.46]-[3.18]; I2 = 86%), nor in Modified Vancouver Scar Scale (MD -0.36; 95% CI [-0.96]-[0.23]; I2 = 0%). Bromelain-based enzymatic debridement may accelerate eschar removal and reduce the need for surgical excision and autografts, without adversely affecting wound closure time or long-term scar quality.

Assessing the role of wound debridement in pyoderma gangrenosum-A retrospective cohort study.

The role of wound debridement in pyoderma gangrenosum (PG) is controversial, largely due to concerns regarding pathergy. This study sought to evaluate the clinical outcomes and utility of wound debridement in PG management. We conducted a retrospective cohort study of 104 patients diagnosed with PG at a single tertiary referral centre, stratified into two treatment groups: those receiving debridement in conjunction with immunosuppressive therapy (n = 38) and those treated with immunosuppression alone (control group, n = 66). The primary outcomes measured were remission (absence of active PG lesions without necessitating additional treatment), time to remission and disease progression (new lesions or expansion of existing ones). Remission was achieved by 60.53% (n = 23) in the debridement group versus 87.88% (n = 58) in the control group (p = 0.003). The mean time to remission was 12.3 months for the debridement group versus 8.67 months for the control group (p = 0.2). Multivariate Cox regression analysis indicated that debridement significantly decreased the likelihood of disease remission (adjusted hazards ratio [HR]: 0.45, 95% confidence interval [CI]: 0.26-0.78, p = 0.005). Disease progression was significantly higher in the debridement group (68.42%, n = 26) compared to the control group (15.15%, n = 10) (p < 0.001). Additionally, 28.95% (n = 11) of patients in the debridement group required repeated procedures, and 10.53% (n = 4) underwent amputations due to deteriorating conditions. The timing and duration of immunosuppressive therapy relative to the procedure did not mitigate the risk of post-surgical exacerbations. These findings suggest that debridement is associated with poorer healing outcomes in PG, advocating for its contraindication in the management of this condition.

Long-term inflammatory outcome after placement of a novel two-piece dental implant in a dog model experimental peri-implantitis.

PURPOSE: Evaluate the inflammatory outcome of a two-piece novel titanium dental implant (test article) vs. a one- piece titanium dental implant (control article) inducing experimental peri-implantitis in a dog model. MATERIALS & METHODS: A novel, two-piece pre-assembled implant with a 0.2-thickness sleeve in its coronal 4.2 mm part was developed (Test article). Ligature-induced experimental periimplantitis model was applied, followed by decontamination and bone grafting in seven dogs. Four groups were assessed according to decontamination and resurfacing protocol: E1 (Experimental 1): test article- sleeve removed, mechanical and chemical decontamination, new rough surface non-threaded sleeve was inserted; E2 (Experimental 2): test article- sleeve removed, mechanical and chemical decontamination, test article remained denuded presenting a turned non-threaded surface; C1 (Control 1): sleeve remained, mechanical and chemical decontamination in test article, original rough surface, non-threaded sleeve; C2 (Control 2): control article cleaning, mechanical and chemical decontamination of original rough surface, threaded implant. Buccolingual and mesiodistal sections were prepared for each site. Resin qualitative and semi-quantitative histopathologic inflammatory parameters were analyzed. RESULTS: Group C1 showed statistically significant highest signs of residual long-term inflammation, followed by groups E1, and C2. Group E2 displayed the lowest local inflammation. Mesio/Distal aspects displayed increased long-term inflammatory infiltrate albeit not statistically significant. CONCLUSIONS: Within the limits of the present study, it may be concluded that - (1) The decontamination procedure is more effective in a commercial one-piece vs. a two-piece dental implant. (2) Mechanical and chemical decontamination outcome is insufficient. Resurfacing improves the decontamination outcome. (3) Decontamination of the turned surface is superior to the rough surface. CLINICAL RELEVANCE: When choosing the most appropriate dental implant for individuals with a high risk for peri-implant disease, a one-piece dental implant with a turned crestal surface is preferable. Once occurring, the control of peri-implant disease inflammation may be more successful. Decontamination is usually not enough. Resurfacing is highly recommended if possible.

Case report of minimally invasive spinal endoscopic debridement and pedicle screw fixation for severe spinal infection of the lumbosacral spine.

Background: Surgical treatment of spinal infections, refractory to medical treatments, is increasing in incidence. Here, we present a unique case of discitis secondary to an iatrogenic cause, spinal steroid injection, that resulted in acute neurology, ventral phlegmon, and osteomyelitis requiring multiple surgical interventions for treatment. Case Description: With the adoption of minimally invasive spinal surgery, the patient underwent full endoscopic debridement and decompression at our hospital. The endoscopic technique offers a unique avenue to the anatomically difficult ventral phlegmon for surgical excision, cultures, and pathogen identification. The endoscopic debridement was paired with percutaneous pedicle screw fixation to stabilize the spine from the worsening bone destruction. Outcome: The patient recovered well postoperatively, with the resolution of her neurological symptoms and improved mobility. Conclusions: Full endoscopic spinal debridement and decompression is a powerful tool to manage severe spinal discitis and preliminary studies encourage its adoption in surgical practices.

Investigating the impact of virtual simulation experiment and massive open online course (MOOC) on medical students' wound debridement training: a quasi-experimental study.

OBJECTIVE: This study aims to evaluate the impact of virtual simulation experiment teaching model and Massive Open Online Course (MOOC) teaching model on the teaching effect in debridement teaching. METHODS: The study adopted a quasi-experimental design and used virtual simulation technology to construct a virtual simulation experimental teaching platform for debridement. This study was conducted at the Second Clinical College of Wuhan University. The experimental group was composed of 135 third-year clinical medicine students in the 2020 grade, who received the virtual simulation experimental teaching model; the control group was 122 third-year students in the same major in the 2019 grade, who used the MOOC teaching model. The performance of the two groups of students was evaluated through theoretical tests and animal experiment operation. In addition, the effectiveness of the experimental teaching model and student satisfaction were evaluated through questionnaire surveys. RESULTS: The theoretical test scores and animal experiment report scores of the experimental group were significantly higher than those of the control group, and the debridement animal experiment operation time of the experimental group was shorter than that of the control group, and the difference was statistically significant (P < 0.05). The post-class questionnaire survey of the experimental group showed that most students were satisfied with the virtual simulation experimental teaching model and believed that it represented the future teaching trend. CONCLUSIONS: In the teaching of debridement, virtual simulation experiment is an effective t teaching model, which not only helps to improve student performance, but also significantly reduces skill operation time and is recognized by students.

Risk factors for fracture-related infections after low-velocity gunshot fractures to the pelvis.

BACKGROUND: Although treatments have improved dramatically in recent years, mortality following gunshot wounds (GSW) to the pelvis continue to range between 3 and 20 %. This project was designed to determine the incidence and risk factors associated with pelvic fracture-related infection (FRI) following GSWs to the pelvis given the paucity of evidence regarding this complication. METHODS: A retrospective review of 13 years (1/2010-12/2022) of patients with GSW to the pelvis was performed. Patients meeting inclusion criteria underwent chart review for the development of pelvic FRI and the following additional data elements were extracted: demographics, presence and type of bowel injury, operations performed, complications, use of postoperative antibiotics (≤24 h vs. >24 h), surgical osseous debridement, presence of retained bullet fragments, and bullet trajectory. Discrete variables were analyzed using Wilcoxon rank-sum test, chi-square, and Fischer's exact test. Pearson correlation coefficients were calculated for continuous variables. RESULTS: 242 patients were included in the study. Concomitant bowel injury was present in 108 patients (45 %). Eleven patients (4.5 %) developed FRI, all of whom had a concomitant bowel injury (p < 0.001). Neither the presence of retained bullet fragments nor the bullet trajectory (through bowel before the bone) was associated with FRI. Antibiotic duration >24 h was not associated with a lower rate of pelvic FRI. CONCLUSION: Development of FRI after a GSW to the pelvis occurs in 4.5 % of patients and is significantly associated with concomitant bowel injury, specifically colonic injury. These findings can be used to help guide further studies on the role of prophylactic antibiotics or other strategies to prevent pelvic FRI.

One-Stage Surgical Management for Cervical Pyogenic Spondylodiscitis by Anterior Debridement, Reconstruction, and Instrumentation: A Single-Center Experience.

OBJECTIVE: Surgical treatment is an effective strategy for cervical pyogenic spondylodiscitis (CPS). However, the optimal surgical approach is uncertain. This study was conducted to evaluate the clinical efficacy of debridement, reconstruction, and instrumentation via the anterior-only approach for CPS. METHODS: We retrospectively collected the data of patients with CPS who underwent one-stage anterior debridement, reconstruction, and instrumentation from January 2013 to December 2022. The surgical duration and blood loss volume were analyzed. The Frankel grading classification was used to evaluate the improvement in neurological function. The visual analog scale and Japanese Orthopaedic Association scores were used to evaluate neck pain and functional recovery. The radiological parameters of regional lordosis angle and C2-C7 Cobb angle were used to evaluate the recovery of cervical alignment. C-reactive protein and erythrocyte sedimentation rate were evaluated to assess the control of infection. RESULTS: Totally, 32 patients were eligible. The surgical duration was 118.9 ± 14.3 minutes, and the blood loss volume was 88.4 ± 42.7 mL. Significant improvements in the Frankel grading were observed in patients with neurological deficits. The visual analog scale and Japanese Orthopaedic Association scores significantly improved postoperatively and during follow-up (P < 0.01). The regional lordosis angle significantly increased from 4.0° ± 6.6° preoperatively to 8.4° ± 5.8° at the final follow-up (P < 0.01). The C2-C7 Cobb angle increased from 11.1° ± 7.1° preoperatively to 13.8° ± 7.2° at the final follow-up (P < 0.01). Bony fusion occurred in all patients. C-reactive protein and erythrocyte sedimentation rate significantly decreased postoperatively and returned to normal during follow-up. CONCLUSIONS: One-stage debridement, reconstruction, and instrumentation via the anterior approach is an effective surgical strategy for CPS. In addition to surgery, targeted and prolonged antibiotic therapy is of crucial importance.

Patient-Reported Outcomes After Periodontal Surgical Procedures.

Background Patient satisfaction is the primary focus of the healthcare system. Patient-reported outcome measures (PROMs) are standardized and valid measures obtained directly from the patients and are used to assess and compare the efficacy of healthcare services. This can help improve the service provided by the healthcare system. Therefore, this study aimed to assess PROMs during the first week post-surgery across different periodontal surgical procedures and explore their correlation with surgical duration. Furthermore, the study sought to evaluate the occurrence of postoperative complications. Methodology A total of 30 healthy patients with no systemic history, requiring periodontal surgical procedures such as crown lengthening (CLP), open flap debridement (OFD), and soft tissue grafting (STG) were included in the study. The Visual Analog Scale (VAS) was utilized for gathering PROMs concerning bleeding, swelling, bruising, and pain at intervals of days zero, three, five, and seven after the surgical procedure. Results On the surgical day and over seven days, VAS scores were the lowest for CLP and highest for STG procedures. This result is in accordance with the duration required for surgery. VAS scores for OFD were intermediate. Prevalence of 20% soft tissue graft dehiscence and 40% tenderness on palpation was observed. Swelling and bleeding were noticed in 10% and 20% of OFD cases. Conclusions One week post-surgically, the mean VAS scores were minimum for CLP, whereas maximum for STG procedures. As CLP and OFD require less duration compared to STG, duration plays a significant role in post-surgical outcomes. Prevalence of the post-surgical complications is also related to the duration of the surgery.

Comparison of CT-Guided needle biopsy versus percutaneous endoscopic debridement and drainage in pathogen identification and pain outcomes for spondylodiscitis patients: A systematic review and literature review.

Introduction: Spondylodiscitis (SD) is an infection of the intervertebral disc with involvement of the adjacent vertebral bodies. Diagnostic tests with CT-guided biopsy only provide a positive yield in 14%-48% of cases. Percutaneous endoscopic debridement and drainage (PEDD) has recently shown promise in the treatment of spondylodiscitis. Research question: The purpose of this study is to determine differences in pathogen identification and clinical outcomes for PEDD versus CT-guided needle biopsy in SD patients. Materials and methods: We conducted a systematic review of the literature using PRISMA guidelines to determine differences in positive microbiology results, perioperative complications, pain control, and long-term clinical outcomes for PEDD vs. CT-guided needle biopsy in SD patients. Results: 1078 studies were evaluated, 87 of which underwent full review. 15 studies met the inclusion and exclusion criteria, including 7 PEDD, 7 CT-guided biopsy, and 1 CT-guided biopsy vs. PEDD article, for a total of 192 PEDD patients and 604 CT-guided biopsy patients. We found 36.59% of CT-guided biopsy patients had positive microbiology results, compared to 84.38% of PEDD patients. No major perioperative complications occurred as a result of the PEDD procedure. Of the five PEDD studies that reported pain outcomes, greater than 80% of patients experienced relief after intervention. Discussion and conclusion: These results suggest that PEDD may improve pathogen identification while simultaneously reducing pain compared to CT-guided needle biopsy in SD. Although current treatment guidelines recommend CT-guided biopsy, in patients with severe back pain and suspected SD, PEDD can be considered an alternative intervention.
