Introducción: La diabetes mellitus tipo 2 (DM2) constituye un problema de salud pública. Objetivos: Determinar la frecuencia de los desbridamientos quirúrgicos y amputaciones de miembros inferiores en pacientes diabéticos tipo 2 y su impacto económico. Materiales y métodos: Se realizó un estudio Observacional descriptivo de corte transversal. Se estimaron los costos médicos directos tanto de desbridamientos quirúrgicos como de amputaciones de miembros inferiores en pacientes diabéticos en el Hospital de Clínicas San Lorenzo, durante el año 2019. Resultados: El total de desbridamientos quirúrgicos y amputaciones de miembros inferiores en el año 2019 representan el 1,9% (314/16.484) de los procedimientos quirúrgicos realizados en el Hospital de Clínicas. El monto total de gastos es de 1.804.185.116 (262.541 USD), de los cuales 172.514.000 (38.857 USD) constituyen gastos de bolsillo y 1.631.671.116 (237.437 USD) constituyen gastos erogados al Estado Paraguayo a través del Hospital de Clínicas de San Lorenzo. Conclusión: Las complicaciones de la diabetes imponen considerables costos tanto en el gasto de bolsillo, al sector de la salud como a la economía en general en el Paraguay, por lo que es necesario re evaluar el manejo de esta problemática teniendo en cuenta el gran impacto que tienen dichos procedimientos producen en la vida de los pacientes a nivel físico, emocional, familiar y social, así como la carga económica que conlleva el tratamiento para el Sistema de Salud.

Introduction: Type 2 diabetes mellitus (T2DM) constitutes a public health problem. Objectives: Determine the frequency of surgical debridement and lower limb amputations in type 2 diabetic patients and their economic impact. Materials and methods: A descriptive cross-sectional observational study was carried out. The direct medical costs of both surgical debridement and lower limb amputations in diabetic patients at the Hospital de Clínicas, San Lorenzo were estimated during 2019. Results: The total of surgical debridement and lower limb amputations in 2019 represents the 1.9% (314/16,484) of surgical procedures performed at the Hospital de Clínicas. The total amount of expenses is 1,804,185,116 (262,541 USD), of which 172,514,000 (38,857 USD) constitute out-of-pocket expenses and 1,631,671,116 (237,437 USD) constitute expenses disbursed to the Paraguayan State through the Hospital de Clínicas de San Lorenzo. Conclusion: The complications of diabetes impose considerable costs both in out-of-pocket spending, on the health sector and on the economy in general in Paraguay, so it is necessary to re-evaluate the management of this problem taking into account the great impact that these procedures have on the lives of patients on a physical, emotional, family and social level, as well as the economic burden that the treatment entails for the Health System.

Mucormycosis of left maxilla: A case report and review

Mucormycosis is an angioinvasive infection caused by fungi of the Zygomycetes order. Rhizopus is the main pathogen responsible for 90% of cases of cerebral mucormycosis. The term rhinocerebral mucormycosis should be used only in the face, palatal, orbital, paranasal sinus, or brain area. Here, we present the case of a 42-year-old man who presented with complaints of pain and swelling in relation to the left upper back tooth region for the past 20 days. In this case, the patient was immunocompromised due to type II diabetes, as well as COVID hospitalization. This case enlightens the investigation, as well as the management protocol followed by post-operative rehabilitation. Early diagnosis and prompt treatment can significantly reduce the morbidity and mortality of these deadly fungal infections.

PROSPECTIVE COMPARATIVE STUDY OF CONSERVATIVE VERSUS OPERATIVE MANAGEMENT AMONG PATIENT WITH CELLULITIS

INTRODUCTION: Cellulitis is a bacterial infection of the skin and subcutaneous tissuethat is more generalized than erysipelas and associated with broken skin and pre-existingulceration. Mild cases of cellulitis are generally treated with oral antibiotics, GlycerinMgSO4 dressing & affected part elevation and severe cases required admission & higherantibiotics, skin & blood culture & sensitivity & in case of systemic symptoms & abscessoperative management is required.AIMS AND OBJECTIVES:• To observe the outcome of conservative and operative patients in view ofcomorbidity and after treatment complications.• Following factors are accounting before conclusive outcome.• To understand the patients characteristics, comorbidity and mode of presentation.• To study spectrum of organism isolated from patient undergoing conservative oroperative management.• To compare treatment modality and outcome in management of cellulitis.MATERIAL & METHODS: Data consists of primary data collected by the principalinvestigator directly from the patients who were admitted from OPD in the GCS medicalcollege and hospital. It was observational study for a period of six months from April2022 to September 2022 under sample size was 50 cases.CONCLUSION: We recommended Operative management over Conservativemanagement in cellulitis because single operative incision can release toxic fluid fromaffected part and can promote faster healing and better recovery and less hospital stay.Patient has less mental trauma, less pain and more economical benefits in Operativemanagement therefore study concludes Operative management is superior Compared toConservative management. However, conservative management is preferable in earlystages of cellulitis.

Nasal Crust-Related Morbidity and Debridement After Endoscopic Skull Base Surgery

Abstract Introduction: Nasal crust after endoscopic skull base surgery can cause nasal congestion, obstruction, and pain, which can affect quality of life. The use of debridement aims to provide symptomatic relief and improve quality of life. Generally, most adult patients tolerate office-based debridement, except in a few select patients that require further sedation in the operating room for a debridement. The study sought to determine the rate of symptomatic crust-related morbidity and the rate of debridement in both the office and the operating room. Methods: Premorbid, operative, and postoperative data of adult patients who had endoscopic skull base surgery in our institution from 2014 to 2018 were reviewed retrospectively. The characteristics of nasal symptoms in the postoperative period were determined and the numberofdebridementsin theoffice and the operatingroomwere analyzed. Results: Two hundred and thirty-four (234) patients with 244 surgeries were included in the study. The majority, 68.9%, had a sellar lesion and a free mucosa graft (FMG) was the most common skull base reconstruction at 53.5%. One hundred and twenty (49.0%) had crust-related symptoms during the postoperative period and 11 patients (4.5%) required the operating room for debridement. The use of a pedicled flap, anxiety, and preoperative radiotherapy were significantly associated with intolerance to in-office debridement (p-value=0.05). Conclusions: The use of a pedicled flap or anxiety may predispose patients to require an OR debridement. Previous radiotherapy also influenced the tolerance to the in-office debridement.

Absceso en dedo por Escherichia vulneris tras traumatismo con una rama

Introducción: Es importante considerar la posible implicación de microorganismos poco frecuentes en infecciones de piel y partes blandas si la muestra obtenida para cultivo es de buena calidad, y además se aísla en cultivo puro, como ocurre con Escherichia vulneris. Caso Clínico: Presentamos en caso de una mujer de 34 años, sin antecedentes mórbidos, quien desarrolló un absceso en el 4° dedo de la mano tras un traumatismo con una rama y que requirió drenaje quirúrgico y tratamiento antibiótico para su resolución. En el contenido del absceso, se aisló E. vulneris en cultivo puro, con un perfil antibiótico multisensible. Discusión y Conclusión: E. vulneris es una enterobacteria cuya patogenicidad ha estado clásicamente discutida, pero que se ha visto que puede tener participación en infección de heridas, especialmente aquellas relacionadas con material vegetal. Este microorganismo, muy relacionado con E. harmannii, presenta buena sensibilidad a los aminoglucósidos, con excepción a la penicilina y al cotrimoxazol. En las infecciones de piel y tejidos blandos causadas por E. vulneris y que cursen como un absceso, es importante realizar desbridamiento quirúrgico, si es necesario para la resolución completa del cuadro, además del tratamiento con amoxicilina/ácido clavulánico que parece adecuado.

Introduction: It is important to assess the possible involvement of rare microorganisms in skin and soft tissue infections if the sample obtained for culture is of good quality, and is isolated in pure culture, as occurs with Escherichia vulneris. Case Report: We present the case of a 34-year-old woman, with no history of morbidity, who developed an abscess in the 4th finger of the hand after trauma with a branch and which required surgical drainage and antibiotic treatment for its resolution. In the content of the abscess, E. vulneris was isolated in pure culture, with a multisensitive antibiotic profile. Discusion: E. vulneris is an Enterobacteriaceae whose pathogenicity has been classically discussed, but it has been seen that it may have participated in the infection of wounds, especially those related to plant material. This organism, closely related to E. harmannii, shows good sensitivity to aminoglycosides, with the exception of penicillin, and cotrimoxazole. In skin and soft tissue infections caused by E. vulneris and that present as an abscess, it is important to perform surgical debridement if necessary for complete resolution of the condition, in addition to treatment with amoxicillin/clavulanic acid, which seems appropriate.

An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique (version 2023) / 中华创伤杂志

Infectious bone defect is bone defect with infection or as a result of treatment of bone infection. It requires surgical intervention, and the treatment processes are complex and long, which include bone infection control,bone defect repair and even complex soft tissue reconstructions in some cases. Failure to achieve the goals in any step may lead to the failure of the overall treatment. Therefore, infectious bone defect has been a worldwide challenge in the field of orthopedics. Conventionally, sequestrectomy, bone grafting, bone transport, and systemic/local antibiotic treatment are standard therapies. Radical debridement remains one of the cornerstones for the management of bone infection. However, the scale of debridement and the timing and method of bone defect reconstruction remain controversial. With the clinical application of induced membrane technique, effective infection control and rapid bone reconstruction have been achieved in the management of infectious bone defect. The induced membrane technique has attracted more interests and attention, but the lack of understanding the basic principles of infection control and technical details may hamper the clinical outcomes of induced membrane technique and complications can possibly occur. Therefore, the Chinese Orthopedic Association organized domestic orthopedic experts to formulate An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique ( version 2023) according to the evidence-based method and put forward recommendations on infectious bone defect from the aspects of precise diagnosis, preoperative evaluation, operation procedure, postoperative management and rehabilitation, so as to provide useful references for the treatment of infectious bone defect with induced membrane technique.

Osteonecrosis of the jaw induced by arsenic trioxide therapy in acute promyelocytic leukemia patient: a case report and literature review / 口腔疾病防治

Objective @#To investigate the etiology, clinical manifestations, treatment and prevention of jaw necrosis caused by arsenic trioxide to provide a reference for clinical diagnosis and treatment. @*Methods@#To analyze the clinical data and related literature of patients with jaw necrosis caused by acute promyelocytic leukemia treated with arsenic trioxide@*Results@#We report a case of jaw necrosis caused by the use of arsenic trioxide (10 mg once a day for one month) during the treatment of acute promyelocytic leukemia. About 20 days after treatment, the patient developed right maxillary pain accompanied by gingival redness and swelling and mucosal ulcer, 14-17 teeth had buccal and palatal alveolar bone exposed, gingival mucosa was missing, gingival tissue was damaged to the bottom of vestibular groove, and palatal soft tissue was damaged to 5-8 mm of palatal suture. Due to the unstable condition of acute promyelocytic leukemia, the patient was given conservative treatment such as oral vitamin and Kangfuxin liquid gargle to keep his mouth clean. Drug induced jaw necrosis reported in the literature can be caused by bisphosphonates. Arsenic trioxide can also cause local jaw necrosis. Clinically, it is often manifested as long-term wound nonunion, pus, alveolar bone or jaw bone exposure, dead bone formation, accompanied by pain, loose teeth, facial swelling and other symptoms. Anti inflammation, debridement and surgical removal of dead bone are commonly used treatment methods.@*Conclusion @# In clinical practice, we should be alert to drug-induced jaw necrosis and strengthen prevention.

Effect evaluation of peroneal osteotomy combined with arthroscopic knee debridement in patients with knee osteoarthritis / 中国医师进修杂志

Objective:To evaluate the effects of peroneal osteotomy combined with arthroscopic knee debridement on perioperative indexes, X-ray indexes, Japanese Orthopaedic Association Assessment score (JOA score), American Hospital for Special Surgery knee score (HSS score) and complication rate of patients with knee osteoarthritis.Methods:A prospective research method was adopted. A total of 110 patients with knee osteoarthritis who were admitted to Chengde Central Hospital from April 2016 to April 2021 were selected as the research objects and divided into the control group (55 cases), the combined group (55 cases) by random number table method. The control group underwent arthroscopic debridement of the knee joint. On the basis of the control group, the combined group was combined with fibula osteotomy. The control group and the combined group were followed up for 6 months after operation. The perioperative indicators, score of JOA before and after 1 month of treatment, X-ray indicators, score of HSS before and after 6 months of treatment, and the incidence of complications during the follow-up period were compared between the control group and the combined group.Results:The operation time of the combined group was longer than that of the control group: (84.36 ± 14.64) min vs. (75.88 ± 12.86) min; compared with before operation, 1 month after operation, the scores of swelling, pain while up and down stairs, walking pain, joint range of motion were increased in the control group and the combined group, and the combined group was higher than the control group: (8.35 ± 0.73) points vs. (6.74 ± 0.67) points, (15.05 ± 1.74) points vs. (13.96±1.66) points, (21.75 ± 2.07) points vs. (18.58 ± 1.73) points, (27.59 ± 3.25) points vs. (25.74 ± 2.83) points; the femoral tibial angle and the range of motion of the knee joint in the control group and the combined group were increased, and the combined group was greater than the control group: (1.94 ± 0.60)° vs. (3.02 ± 0.67)°; the scores of stability, flexion deformity, muscle strength, range of motion, function, and pain in the control group and the combined group increased, and the combined group was higher than the control group: (8.62 ± 0.86) points vs. (6.89 ± 0.78) points, (7.86 ± 0.96) points vs. (6.27 ± 0.68) points, (7.79 ± 0.62) points vs. (6.95 ± 0.57) points, (14.95 ± 2.60) points vs. (12.48 ± 2.33) points, (17.46 ± 2.21) points vs. (14.59 ± 1.76) points, (24.83 ± 3.25) points vs. (18.59 ± 2.57) points, the difference was statistically significant ( P<0.05). During the following up period, there were no significant differences in the incidences of osteofascial compartment syndrome, neurovascular injury, intraarticular adhesion and incision infection between the two groups ( P>0.05). Conclusions:The operation time of fibular osteotomy combined with arthroscopic debridement of knee joint in patients with knee osteoarthritis was longer, but fibular osteotomy combined with arthroscopic debridement of the knee joint can reduce the valgus of the patient and improve the range of motion of the joint. It could effectively reduce the degree of pain and improve the function of knee joint, and the safety was good, with good therapeutic effect.

A reflection on medical treatment of radionuclide-contaminated wounds during medical response to nuclear emergencies / 中国辐射卫生

Radionuclide-contaminated wounds are common in medical response to nuclear emergencies, which have different manifestations in different types of accidents. Medical treatment is the key part of the response. Based on the drill experience gained from medical response to nuclear emergencies, the authors summarize the research advances in radionuclide-contaminated wounds in recent years, mainly involving the biokinetic characteristics, medical response, surgical debridement, and prevention and treatment of internal contamination of radionuclide-contaminated wounds; the authors summarize the key points of technical operations and provide suggestions on improvements in the drills. The authors believe that medical treatment of radionuclide-contaminated wounds requires highly compatible integration of the practical skills from clinical medicine and radiological knowledge; emergency response, surgical debridement, and prevention and treatment of internal contamination all together constitute an integrated rescue and treatment strategy with internal logic correlations. However, targeted improvements are needed to achieve desired effects in the drills.

Debridement， Antibiotics and Implant Retention for the Treatment of Periprosthetic Joint Infection After Arthroplasty： A Narrative Review / 中山大学学报(医学科学版)

Periprosthetic joint infection （PJI） following joint arthroplasty is devastating and technique-demanding. At present， the surgical treatment for PJI includes debridement， antibiotics， and implant retention （DAIR）， single- or two-stage revision， arthrodesis， and amputation. DAIR is appealing to both surgeons and patients as it can avoid unnecessary implants removal， making it less time-consuming and less invasive. In this article， we review the current knowledge in surgical timing， intraoperative details and antibiotics strategy of DAIR.

Surgical management of chronic osteomyelitis: Organisms, recurrence and treatment outcome / 中华创伤杂志(英文版)

PURPOSE@#The study aimed to identify the risk factors of recurrence in chronic osteomyelitis (COM) and to document the microbiological patterns pre- and intra-operatively and at recurrence, if any.@*METHODS@#We performed retrospective review on COM patients treated with surgical debridement and a 6-week course of antibiotics. The patients with symptoms of osteomyelitis for at least 6 weeks, present or past episodes of discharging sinus, documentation of bone sequestration in operative notes or preoperative images were included in the study. Patients with symptoms of osteomyelitis < 6 weeks, lack of history of discharging sinus or lack of evidence of sequestration in preoperative images or intraoperative notes were excluded. Logistic regression models were used to assess the impact of risk factors of recurrence. Cohen-Kappa scores were derived to see the concordance between pre-operative and intra-operative isolates and at recurrence.@*RESULTS@#Totally, 147 COM patients (115 males and 32 females, mean age (33 ± 19) years) were included in this study. Recurrence was noted in 28 patients (19.0%). Polymicrobial growth and extended spectrum beta-lactamase producing Enterobacteriaceae increased the chance of recurrence. Cierny-Mader stage-1, hematogenous aetiology and negative intraoperative culture reduced the chance of recurrence. Concordance between pre-operative and intra-operative cultures was 59.85% (Kappa score 0.526, p < 0.001) and between index surgery and at recurrence was 23.81% (Kappa score 0.155, p < 0.001). Lack of knowledge of causative organism preoperatively did not affect outcome. At mean follow-up (42 ± 15) months, all patients were apparently infection free for at least 1 year.@*CONCLUSION@#Polymicrobial growth and multi-drug resistant organisms increase the risk of recurrence in COM. Patients' age, gender, diabetes mellitus, previous failed treatment, duration of symptoms, haemoglobin, white cell count, C-reactive protein and erythrocyte sedimentation rate at presentation did not have any impact on the recurrence of infection. Pre-operative isolation of organism is of questionable value. Recurrences of infections do occur and are more of re-infections than relapses. Diligent isolation of organism must be attempted even in re-debridements. Even patients with recurrences do well with appropriate debridement and antibiotic therapy.

Administração de Lactobacillus para casei 28.4 como terapia adjuvante no tratamento da periodontite: desenvolvimento in vitro de formulação probiótica usando gellan gum e ensaio clínico randomizado placebo controlado / Administration of Lactobacillus paracasei 28.4 as adjuvant therapy in the treatment of periodontitis: in vitro development of the probiotic formulation using gellan gum and placebo-controlled randomized clinical trial

A periodontite é uma doença inflamatória do periodonto associada ao acúmulo de biofilme dental, com consequente disbiose da microbiota oral e alteração da resposta imuno-inflamatória. O controle da periodontite realizado por meio do tratamento periodontal não-cirúrgico altera o ambiente subgengival e pode ser associado a terapias adjuntas. O uso de probióticos como terapia adjuvante a esse tratamento parece favorecer a modificação do biofilme bacteriano e resposta imuno-inflamatória. Entretanto, os probióticos empregados até o momento não são próprios da cavidade oral e, por isso, a busca por cepas originadas da microbiota oral tem ganhado espaço na tentativa de favorecer a aderência e colonização permanente dessas bactérias. Recentemente, a cepa de Lactobacillus paracasei 28.4 foi isolada da cavidade oral, exibindo atividades antimicrobianas promissoras sobre o controle de patógenos orais. O presente estudo teve como objetivos o desenvolvimento de uma formulação probiótica de L. paracasei 28.4 incorporado em gellan gum para uso humano, bem como a avaliação dos efeitos clínicos da administração desta formulação como adjuvante no tratamento periodontal. Para tal, o trabalho foi dividido em 2 etapas, contemplando uma etapa laboratorial (parte A), para desenvolvimento da formulação probiótica; e um ensaio clínico randomizado (parte B, n=40), envolvendo um protocolo de tratamento periodontal não cirúrgico associado à terapia adjunta probiótica ou placebo. Os resultados da parte A permitiram encontrar a melhor forma de apresentação e armazenamento da formulação de gellan gum. Na parte B, aos 3 e 6 meses de acompanhamento, os dois grupos apresentaram melhoras significativas dos parâmetros periodontais (índice de sangramento, índice gengival, profundidade de sondagem e ganho de nível de inserção) em relação ao baseline, sem diferença estatística na comparação intergrupo. Como conclusão, uma formulação probiótica segura e possível de ser aplicada na prática clínica foi obtida; no entanto, sua administração não promoveu efeitos clínicos adicionais ao tratamento de pacientes com periodontite generalizada estágios III/IV e graus B/C (AU)

Periodontitis is an inflammatory disease of the periodontium associated with the accumulation of dental biofilm, with consequent dysbiosis of the oral microbiota and alteration of the immune-inflammatory responseThe control of periodontitis carried out through non-surgical periodontal treatment alters the subgingival environment and can be associated with adjunctive therapies.The use of probiotics as an adjuvant therapy in the periodontal treatment seems to favor the modification of the bacterial biofilm and modulation of the immuneinflammatory response. However, the probiotics used so far are not specific to the oral cavity and, therefore, the search for strains originating from the oral microbiota has gained space to favor the adherence and permanent colonization of these bacteria. Recently, strain of Lactobacillus paracasei 28.4 was isolated from the oral cavity itself, showing promising antimicrobial activities in the control of oral pathogens. The present study aimed to develop and characterize a probiotic formulation of L. paracasei 28.4 incorporated into gellan gum for human use, as well as to evaluate the clinical effects of administering this formulation as an adjuvant in the treatment of periodontitis. To this end, the study was divided into 2 stages, comprising a laboratory stage (part A), for the development of the probiotic, and a randomized clinical trial (part B, n=40) contemplating a non-surgical periodontal treatment protocol associated with adjunctive probiotic therapy or placebo. The results from part A made it possible to find the best way to present and store the gellan gum formulation. In part B, at 3 and 6 months of follow-up, both groups showed significant improvements in periodontal parameters (bleeding index, gingival index, probing depth and attachment level gain) in relation to baseline, with no statistical difference in the intergroup comparison. In conclusion, a safe probiotic formulation that can be applied in clinical practice was obtained; however, its administration did not promote additional clinical effects in the treatment of patients with stage III/IV and grades B/C generalized periodontitis (AU)

Tratamiento de las fracturas por herida de arma de fuego: revisión bibliográfica sistematizada / Treatment of gunshot wound fractures: systematic review of the literature / Tratamento de fraturas por arma de fogo: revisão bibliográfica sistematizada

Introducción: Las fracturas por heridas de arma de fuego son un motivo de consulta habitual en nuestro país. Existe gran variabilidad de conductas respecto a su tratamiento. El objetivo principal de este trabajo es analizar los distintos tratamientos y sus indicaciones. Materiales: Se realizó una revisión sistematizada de la literatura en las bases de datos Pubmed y Scielo. Se incluyeron artículos con fracturas por herida de arma de fuego en miembros superiores e inferiores, excluyendo la mano. Se analizó: tratamiento (ortopédico o quirúrgico), debridamiento, antibioticoterapia y complicaciones. Resultados: Se obtuvieron 19 artículos que cumplían los criterios de inclusión y exclusión. Los artículos tuvieron un Nivel de Evidencia tipo 2b, 3 y 4. Conclusiones: Los artículos analizados tienen un bajo nivel de evidencia. La fijación quirúrgica es variable y depende de la topografía ósea, la lesión de partes blandas y las lesiones asociadas. El debridamiento profundo está relacionado con mayores índices de infección. Las fracturas estables de tratamiento ortopédico no deberían debridarse ya que aumenta los índices de infección. Debería realizarse antibioticoterapia intravenosa inicial en todos los pacientes, la terapia posterior es discutida.

Introduction: Fractures due to gunshot wounds are a common reason for consultation in our country. There is great variability of conduct regarding its treatment. The main objective of this work is to analyze the different treatments and their indications. Materials: A systematic review of the literature was carried out in the Pubmed and Scielo databases. Articles with fractures due to gunshot wounds in the upper and lower limbs (excluding the hand) were included. We analyzed: treatment (orthopedic or surgical), debridement, antibiotic therapy and complications. Results: 19 articles were obtained that met the inclusion and exclusion criteria. The articles had a Level of Evidence type 2b, 3 and 4. Conclusions: The articles analyzed have a low level of evidence. Surgical fixation is variable and depends on bone topography, soft tissue injury, and associated injuries. Deep debridement is associated with higher rates of infection. Stable orthopedically treated fractures should not be debrided as this increases infection rates. Initial intravenous antibiotic therapy should be performed in all patients, subsequent therapy is discussed.

Necrotizing fasciitis and fatal septic shock associated with Streptococcus constellatus

ABSTRACT Streptococcus constellatus is usually a benign, commensal bacteria but has increased incidence in blood cultures and abscesses. This pathogenic involvement is most prevalent in individuals with underlying medical conditions, such as solid tumors and type 2 diabetes mellitus, as well as in cases of community-acquired infections. We report a 43-year-old male with a right medial thigh ulcer and necrotic scrotal skin. The wound culture from surgical debridement grew Streptococcus constellatus, and histology was consistent with stage III necrotizing fasciitis. Regardless of etiology, the mortality rate of patients with necrotizing fasciitis is greatly decreased with early intervention and thorough surgical debridement.

Macroporous latex biomembrane from Hancornia speciosa modulates the inflammatory process and has a debridement effect on wound healing in rats

Purpose: The angiogenic, osteogenic and anti-inflammatory activity of latex of Hancornia speciosa has been evidenced and indicates pharmacological potential with great applicability in the health area, especially in the wound healing process. The present work aimed to compare the effects of the H. speciosa macroporous latex biomembrane with saline on wound healing. Methods: Forty-three Wistar rats were submitted to excisional wound induction procedure and divided into groups according to treatment: saline (G1), and macroporous biomembrane (G2). The animals were euthanized at three, seven, 14, and 21 days after injury induction (DAI), and three animals were used for the debridement test. Morphometric, macroscopic, and microscopic analyses of general pathological processes were performed. Results: The macroporous biomembrane minimized necrosis and inflammation during the inflammatory and proliferative phases of the healing process, confirmed by the lower intensity of the crust and the debridement effect. In addition, the wounds treated with the macroporous biomembrane presented greater contraction rates in all the experimental periods analyzed. Conclusions: The macroporous biomembrane presents angiogenic, anti-inflammatory and debridement effects, contributing to the healing process, and can be considered a potentially promising new biomaterial to be used as a dressing.

Manuka Honey as an Adjunct to Nonsurgical Periodontal Treatment: A Pilot Study

@#This pilot study evaluated the effect of manuka honey as a subgingival adjunct to scaling and root surface debridement in the treatment of periodontitis. This study used a split-mouth design with a 3-month follow-up in seven participants diagnosed with periodontitis Stage III Grade B or C. Root surface debridement was performed on one side of the mouth (control); the other side received debridement plus manuka honey application (test). Clinical parameters were recorded at baseline, 6- and 12-weeks. Gingival crevicular fluid and subgingival plaque were sampled. Microbiological outcomes were analysed using benzoylarginine pnitroanilide assay and polymerase chain reaction assay. Single application of manuka honey to periodontal pockets did not result in additional reduction of pocket depth, improvement of attachment levels or changes in p-nitroaniline enzymes when compared with root surface debridement alone. However, test sites exhibited greater reduction in bleeding than control sites, mean differences 1.3 (95%CI 1.2-1.5) and 1.7 (95%CI 1.5-1.9) at 6-weeks and 12-weeks, respectively. The proportion of mutans streptococci decreased at 6-weeks in test sites but increased at 12-weeks in control sites. Adjunctive application of manuka honey to periodontal pockets improved gingival inflammation but did not demonstrate significant clinical benefits compared with root surface debridement alone.

Analysis of risk factors for failure in the treatment of early periprosthetic joint infection by debridement, antibioticsand implant retention combined with intra-articular injection of antibiotics / 中华骨科杂志

Objective:To analyze the risk factors leading to the failure of early periprosthetic joint infection (PJI) treated by debridement, antibiotics and implant retention (DAIR) combined with intra-articular injection of antibiotics.Methods:A total of 100 patients who received DAIR combined with intra-articular injection of antibiotics between January 2010 and October 2020 in the Department of Orthopaedics, First Affiliated Hospital of Xinjiang Medical University, were retrospectively analyzed. There were 47 males and 53 females, with an average age of 62.8±13.0 years (26-84 years). 75 patients were diagnosed as PJI after primary surgery while 25 PJI after revision or debridement, involving 41 hips and 59 knees. According to the clinical outcomes, the patients were divided into the cured group (78 cases) and the uncured group (22 cases). Risk factors were screened by univariate analysis on their gender, age, body mass index, site of infection (hip/knee), synovial white blood cell count, erythrocyte sedimentation rate (ESR), C reactive protein (CRP), time of infection, types of pathogenic bacteria (gram-positive bacteria, gram-negative bacteria or fungi), preoperative sinus tract and previous surgical history. For the factors with P<0.20, multivariate binary logistic regression analysis was performed to determine the independent risk factors. Kaplan-Meier survival curve was drawn and any cause that led to treatment failure was seen as the end point event. Calculate prosthetic survival time and 10-year survival rate. Results:The average follow-up was 59.8±40.6 months (0.3-129.0 months). The infection control rate of DAIR combined with intra-articular injection of antibiotics in the treatment of early PJI was 78% (78/100). The univariate analysis showed that the successful rate of non-fungal infection group (81%, 77/95) was significantly higher than the fungal infection group (20%, 1/5) and the successful rate of the group without previous surgical history (85.3%, 64/75) was significantly higher than that with previous surgical history (56.0%, 14/25, χ 2=7.07, P=0.008; χ 2=9.40, P=0.002). The multivariate binary Logistic regression analysis showed that fungal infection [ OR=0.08, 95% CI(0.01, 0.79), P=0.031] and history of previous surgical intervention [ OR=0.25, 95% CI(0.09, 0.73), P=0.001] were independent risk factors for treatment failure. Kaplan-Meier survival curves showed that the survival time of the prosthesis was 96.83±5.30 months, and the 10-year survival rate was 68.1%. Meanwhile, the survival rate of patients with fungal infection and previous surgical history was significantly lower than that of patients without fungal infection or previous surgical history, the difference was statistically significant (χ 2=15.49, P<0.001; χ 2=8.91, P=0.030). Conclusion:The time of PJI, bacterial virulence and species, and preoperative inflammatory indicators had no effect on the outcome of DAIR combined with intra-articular injection of antibiotics in the treatment of early PJI. However, DAIR was not recommended for patients with a history of surgical intervention and fungal infection.

A case report of suppurative acromioclavicular arthritis and literature review / 中华骨科杂志

One case of suppurative acromioclavicular arthritis caused by Staphylococcus aureuswas reported. The patient was admitted to hospital due to swelling and pain in the right shoulder, limited mobility without no obvious cause.Through medical history, physical examination, imaging examination, and local tissue bacterial culture, it was confirmed that the infection was caused by Staphylococcus aureus. After surgery and anti infection treatment, satisfactory treatment results were achieved. Through literature review, 95 cases of suppurative acromioclavicular arthritis were retrieved and analyzed from 57 articles.Among them, 26 cases (27%) were infected with Staphylococcus aureus, including 3 cases of clearly identified methicillin-resistant Staphylococcus aureus, 2 cases of methicillin-sensitive Staphylococcus aureus, and 1 case of methicillin-resistant Staphylococcus epidermidis; 13 cases (14%) of Streptococcus; There were 6 cases (6%) of special pathogens, including 2 cases of Haemophilus parainfluenzae, 1 case of Candida, 1 case of Bacillus pallidum, 1 case of Mycobacterium avium, and 1 case of Pasteurella multocida; 50 cases (53%) of specific infections with pathogens were not clearly reported. Suppurative acromioclavicular arthritis has the characteristics of difficult early diagnosis, rapid disease progression, and strong destructiveness. MRI and ultrasound have high specificity and sensitivity in the diagnosis of this disease, and ultrasound can assist in obtaining joint fluid for examination. Early identification of the pathogen is the key to the treatment of this disease. Before identifying the pathogen, antibiotics should not be used arbitrarily. After diagnosis, timely anti infection treatment should be carried out, and if necessary, surgical debridement should be performed. The vast majority of patients can achieve satisfactory and accurate treatment results after active and standardized treatment.
