RESUMO
The International Working Group on the Diabetic Foot (IWGDF) has published evidence-based guidelines on the management and prevention of diabetes-related foot diseases since 1999. The present guideline is an update of the 2019 IWGDF guideline on the diagnosis and management of foot infections in persons with diabetes mellitus. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework was used for the development of this guideline. This was structured around identifying clinically relevant questions in the P(A)ICO format, determining patient-important outcomes, systematically reviewing the evidence, assessing the certainty of the evidence, and finally moving from evidence to the recommendation. This guideline was developed for healthcare professionals involved in diabetes-related foot care to inform clinical care around patient-important outcomes. Two systematic reviews from 2019 were updated to inform this guideline, and a total of 149 studies (62 new) meeting inclusion criteria were identified from the updated search and incorporated in this guideline. Updated recommendations are derived from these systematic reviews, and best practice statements made where evidence was not available. Evidence was weighed in light of benefits and harms to arrive at a recommendation. The certainty of the evidence for some recommendations was modified in this update with a more refined application of the GRADE framework centred around patient important outcomes. This is highlighted in the rationale section of this update. A note is also made where the newly identified evidence did not alter the strength or certainty of evidence for previous recommendations. The recommendations presented here continue to cover various aspects of diagnosing soft tissue and bone infections, including the classification scheme for diagnosing infection and its severity. Guidance on how to collect microbiological samples, and how to process them to identify causative pathogens, is also outlined. Finally, we present the approach to treating foot infections in persons with diabetes, including selecting appropriate empiric and definitive antimicrobial therapy for soft tissue and bone infections; when and how to approach surgical treatment; and which adjunctive treatments may or may not affect the infectious outcomes of diabetes-related foot problems. We believe that following these recommendations will help healthcare professionals provide better care for persons with diabetes and foot infections, prevent the number of foot and limb amputations, and reduce the patient and healthcare burden of diabetes-related foot disease.

BACKGROUND: Securing an early accurate diagnosis of diabetic foot infections and assessment of their severity are of paramount importance since these infections can cause great morbidity and potential mortality and present formidable challenges in surgical and antimicrobial treatment. METHODS: In June 2022, we searched the literature using PubMed and EMBASE for published studies on the diagnosis of diabetic foot infection (DFI). On the basis of pre-determined criteria, we reviewed prospective controlled, as well as non-controlled, studies in English. We then developed evidence statements based on the included papers. RESULTS: We selected a total of 64 papers that met our inclusion criteria. The certainty of the majority of the evidence statements was low because of the weak methodology of nearly all of the studies. The available data suggest that diagnosing diabetic foot infections on the basis of clinical signs and symptoms and classified according to the International Working Group of the Diabetic Foot/Infectious Diseases Society of America scheme correlates with the patient's likelihood of the need for hospitalisation, lower extremity amputation, and risk of death. Elevated levels of selected serum inflammatory markers such as erythrocyte sedimentation rate (ESR), C-reactive protein and procalcitonin are supportive, but not diagnostic, of soft tissue infection. Culturing tissue samples of soft tissues or bone, when care is taken to avoid contamination, provides more accurate microbiological information than culturing superficial (swab) samples. Although non-culture techniques, especially next-generation sequencing, are likely to identify more bacteria from tissue samples including bone than standard cultures, no studies have established a significant impact on the management of patients with DFIs. In patients with suspected diabetic foot osteomyelitis, the combination of a positive probe-to-bone test and elevated ESR supports this diagnosis. Plain X-ray remains the first-line imaging examination when there is suspicion of diabetic foot osteomyelitis (DFO), but advanced imaging methods including magnetic resonance imaging (MRI) and nuclear imaging when MRI is not feasible help in cases when either the diagnosis or the localisation of infection is uncertain. Intra-operative or non-per-wound percutaneous biopsy is the best method to accurately identify bone pathogens in case of a suspicion of a DFO. Bedside percutaneous biopsies are effective and safe and are an option to obtain bone culture data when conventional (i.e. surgical or radiological) procedures are not feasible. CONCLUSIONS: The results of this systematic review of the diagnosis of diabetic foot infections provide some guidance for clinicians, but there is still a need for more prospective controlled studies of high quality.

The optimal approaches to managing diabetic foot infections remain a challenge for clinicians. Despite an exponential rise in publications investigating different treatment strategies, the various agents studied generally produce comparable results, and high-quality data are scarce. In this systematic review, we searched the medical literature using the PubMed and Embase databases for published studies on the treatment of diabetic foot infections from 30 June 2018 to 30 June 2022. We combined this search with our previous literature search of a systematic review performed in 2020, in which the infection committee of the International Working Group on the Diabetic Foot searched the literature until June 2018. We defined the context of the literature by formulating clinical questions of interest, then developing structured clinical questions (Patients-Intervention-Control-Outcomes) to address these. We only included data from controlled studies of an intervention to prevent or cure a diabetic foot infection. Two independent reviewers selected articles for inclusion and then assessed their relevant outcomes and methodological quality. Our literature search identified a total of 5,418 articles, of which we selected 32 for full-text review. Overall, the newly available studies we identified since 2018 do not significantly modify the body of the 2020 statements for the interventions in the management of diabetes-related foot infections. The recent data confirm that outcomes in patients treated with the different antibiotic regimens for both skin and soft tissue infection and osteomyelitis of the diabetes-related foot are broadly equivalent across studies, with a few exceptions (tigecycline not non-inferior to ertapenem [±vancomycin]). The newly available data suggest that antibiotic therapy following surgical debridement for moderate or severe infections could be reduced to 10 days and to 3 weeks for osteomyelitis following surgical debridement of bone. Similar outcomes were reported in studies comparing primarily surgical and predominantly antibiotic treatment strategies in selected patients with diabetic foot osteomyelitis. There is insufficient high-quality evidence to assess the effect of various recent adjunctive therapies, such as cold plasma for infected foot ulcers and bioactive glass for osteomyelitis. Our updated systematic review confirms a trend to a better quality of the most recent trials and the need for further well-designed trials to produce higher quality evidence to underpin our recommendations.

RESUMO
BACKGROUND: Community physicians may not encounter Charcot arthropathy frequently, and its symptoms and signs may be nonspecific. Patients often have a delay of several months before receiving a formal diagnosis and referral for specialty care. However, limited Canadian data are available. We evaluated the clinical history, treatment and outcomes of patients treated for Charcot arthropathy after prompt referral and diagnosis. METHODS: We performed a retrospective chart review of 76 patients with diabetes (78 feet) who received nonoperative treatment for Charcot arthropathy in a specialty foot clinic between Jan. 20, 2009, and Mar. 26, 2018. Patients were referred to the foot clinic by community physicians for evaluation or were pre-existing patients at the foot clinic with new-onset Charcot arthropathy. RESULTS: Of the 78 feet included in our analyses, 52 feet (67%) were evaluated initially by a community physician and referred to the foot clinic, where they were seen within 3 ± 5 weeks. The remaining 26 feet (33%) were already being treated at the foot clinic. Most feet had swelling, erythema, warmth, a palpable pulse and loss of protective sensation. Ulcers were present initially in 23 feet (29%). Sixty-four feet (82%) with Charcot arthropathy were in Eichenholtz classification stage 1 and most had midfoot involvement. Nonoperative treatment included total contact casting (60 feet, 77%). Mean duration of nonoperative treatment until resolution for 55 feet (71%) was 6 ± 5 months. Surgery was performed on 20 feet (26%) for the treatment of infection and recurrent ulcer associated with deformity, including 6 (8%) lower limb amputations. CONCLUSION: Charcot arthropathy may resolve in most feet with early referral and nonoperative treatment, but remains a limb-threatening condition.

BACKGROUND: Colorectal injury from an intrauterine device (IUD) is rare but may lead to major complications. CASE: A 55-year-old woman presented to a tertiary care hospital with 4 days of generalized weakness, confusion, dysuria, and lower back pain. She provided a vague history of an unsuccessful attempt to remove an IUD 30 years prior. A computed tomography scan demonstrated an IUD in the rectal lumen, with gluteal and pelvic gas and fluid collections. Emergency surgery found necrotizing fasciitis. Despite multiple debridements, sigmoidoscopic IUD removal, and long-term intravenous antibiotics, the patient died from sepsis and multiorgan failure. CONCLUSION: IUDs require proper monitoring and timely removal to prevent potential complications associated with organ perforation.

RATIONALE & OBJECTIVES: Chronic kidney disease (CKD) is a potent risk factor for macrovascular disease and death. Peripheral artery disease (PAD) is more common in patients with CKD and is associated with lower-limb complications and mortality. We sought to compare the prevalence of PAD in and outside the setting of kidney disease and examine how PAD affects the risk for adverse health outcomes, specifically lower-limb complications, cardiovascular events, and survival. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: 453,573 adult residents of Manitoba with at least 1 serum creatinine measurement between 2007 and 2014. EXPOSURE: PAD defined by hospital discharge diagnosis codes and medical claims. OUTCOMES: All-cause mortality, cardiovascular events, and lower-limb complications, including foot ulcers and nontraumatic amputations. ANALYTICAL APPROACH: Survival analysis using Cox proportional hazards models. RESULTS: The prevalence of PAD in our study population was 4.5%, and patients with PAD were older, were more likely to be male, and had a higher burden of comorbid conditions, including diabetes and CKD. PAD was associated with higher risks for all-cause mortality, cardiovascular events, and lower-limb complications in patients with estimated glomerular filtration rate (eGFR) ≥ 60mL/min/1.73m2, those with CKD GFR categories 3 to 5 (G3-G5), and those treated by dialysis (CKD G5D). Although HRs for PAD were lower in the CKD population, event rates were higher as compared with those with eGFR≥60mL/min/1.73m2. In particular, compared with patients with eGFR≥60mL/min/1.73m2 and without PAD, patients with CKD G5D had 10- and 12-fold higher risks for lower-limb complications, respectively (adjusted HRs of 10.36 [95% CI, 8.83-12.16] and 12.02 [95% CI, 9.58-15.08] for those without and with PAD, respectively), and an event rate of 75/1,000 patient-years. LIMITATIONS: Potential undercounting of PAD and complications using administrative codes and the limited ability to examine quality-of-care indicators for PAD. CONCLUSIONS: PAD is more common in patients with CKD G3-G5 and G5D compared with those with eGFR≥60mL/min/1.73m2 and frequently leads to lower-limb complications. Medical interventions and care pathways specifically designed to slow or prevent the development of lower-limb complications in this population are urgently needed.

The optimal approaches to managing diabetic foot infections remain a challenge for clinicians. Despite an exponential rise in publications investigating different treatment strategies, the various agents studied generally produce comparable results, and high-quality data are scarce. In this systematic review, we searched the medical literature using the PubMed and Embase databases for published studies on the treatment of diabetic foot infections as of June 2018. This systematic review is an update of previous reviews, the first of which was undertaken in 2010 and the most recent in 2014, by the infection committee of the International Working Group of the Diabetic Foot. We defined the context of literature by formulating clinical questions of interest, then developing structured clinical questions (PICOs) to address these. We only included data from controlled studies of an intervention to prevent or cure a diabetic foot infection. Two independent reviewers selected articles for inclusion and then assessed their relevant outcomes and the methodological quality. Our literature search identified a total of 15 327 articles, of which we selected 48 for full-text review; we added five more studies discovered by means other than the systematic literature search. Among these selected articles were 11 high-quality studies published in the last 4 years and two Cochrane systematic reviews. Overall, the outcomes in patients treated with the different antibiotic regimens for both skin and soft tissue infection and osteomyelitis of the diabetic foot were broadly equivalent across studies, except that treatment with tigecycline was inferior to ertapenem (±vancomycin). Similar outcomes were also reported in studies comparing primarily surgical and predominantly antibiotic treatment strategies in selected patients with diabetic foot osteomyelitis. There is insufficient high-quality evidence to assess the effect of various adjunctive therapies, such as negative pressure wound therapy, topical ointments or hyperbaric oxygen, on infection related outcomes of the diabetic foot. In general, the quality of more recent trial designs are better in past years, but there is still a great need for further well-designed trials to produce higher quality evidence to underpin our recommendations.

METHODS: In June 2018, we searched the literature using PuEbMed and EMBASE for published studies on the diagnosis of diabetic foot infection. On the basis of predetermined criteria, we reviewed prospective controlled, as well as noncontrolled, studies in any language, seeking translations for those not in English. We then developed evidence statements on the basis of the included papers. RESULTS: From the 4242 records screened, we selected 35 papers that met our inclusion criteria. The quality of all but one of the evidence statements was low because of the weak methodology of nearly all of the studies. The available data suggest that diagnosing diabetic foot infections on the basis of clinical signs and symptoms and classified according to the International Working Group of the Diabetic Foot scheme correlates with the patient's likelihood of ulcer healing, of lower extremity amputation, and risk of death. Elevated levels of selected serum inflammatory markers are supportive, but not diagnostic, of soft tissue or bone infection. In patients with suspected diabetic foot osteomyelitis, both a positive probe-to-bone test and an elevated erythrocyte sedimentation rate are strongly associated with its presence.

Plain X-ray remains the first-line imaging examination when there is suspicion of diabetic foot osteomyelitis, but advanced imaging methods help in cases when either the diagnosis or the localization of infection is uncertain. CONCLUSION: The results of this first reported systematic review on the diagnosis of diabetic foot infections provide some guidance for clinicians, but there is a need for more prospective controlled studies of high quality.

The International Working Group on the Diabetic Foot (IWGDF) has published evidence-based guidelines on the prevention and management of diabetic foot disease since 1999. This guideline is on the diagnosis and treatment of foot infection in persons with diabetes and updates the 2015 IWGDF infection guideline. On the basis of patient, intervention, comparison, outcomes (PICOs) developed by the infection committee, in conjunction with internal and external reviewers and consultants, and on systematic reviews the committee conducted on the diagnosis of infection (new) and treatment of infection (updated from 2015), we offer 27 recommendations. These cover various aspects of diagnosing soft tissue and bone infection, including the classification scheme for diagnosing infection and its severity. Of note, we have updated this scheme for the first time since we developed it 15 years ago. We also review the microbiology of diabetic foot infections, including how to collect samples and to process them to identify causative pathogens. Finally, we discuss the approach to treating diabetic foot infections, including selecting appropriate empiric and definitive antimicrobial therapy for soft tissue and for bone infections, when and how to approach surgical treatment, and which adjunctive treatments we think are or are not useful for the infectious aspects of diabetic foot problems. For this version of the guideline, we also updated four tables and one figure from the 2016 guideline. We think that following the principles of diagnosing and treating diabetic foot infections outlined in this guideline can help clinicians to provide better care for these patients.

BACKGROUND: Pasteurella species are Gram-negative coccobacilli that are a part of the normal oropharyngeal flora of numerous domestic animals. They have been recognized as a rare but significant cause of peritonitis in patients undergoing peritoneal dialysis (PD). A consensus about management strategies for PD-associated peritonitis caused by Pasteurella species currently does not exist. METHODS: The microbiological database serving the Manitoba Renal Program was searched from 1997 to 2013 for cases of Pasteurella species PD-associated peritonitis, and charts were reviewed. PubMed was searched for case reports and data were abstracted. RESULTS: Seven new local cases and 30 previously reported cases were analyzed. This infection is clinically similar to other forms of PD peritonitis, with household pet exposure appearing to be the strongest risk factor. Cats are the most commonly implicated pet. Direct contact between the pet and the equipment was commonly reported (25 of 37 patients) but was not necessary for infection to develop. The mean duration of treatment was 15 days. Complication rates were low, with only 11% of patients requiring PD catheter removal. There was no mortality reported. CONCLUSION: Pasteurella species are a rare cause of PD-associated peritonitis that can be successfully treated with a two-week course of intraperitoneal antibiotics with a high likelihood of catheter salvage.
HISTORIQUE: Les espèces de Pasteurella sont des coccobacilles à Gram négatif qui font partie de la flore oropharyngée normale de nombreux animaux domestiques. Ils constituent une cause de péritonite rare, mais importante, chez les patients sous dialyse péritonéale (DP). Il n'y a pas de consensus quant aux stratégies de prise en charge de la péritonite associée à la dialyse péritonéale causée par les espèces de Pasteurella. MÉTHODOLOGIE: Les chercheurs ont exploré la base de données microbiologiques du Programme de lutte contre la maladie du rein du Manitoba de 1997 à 2013 pour déceler les cas de péritonite associée à la DP causée par les espèces de Pasteurella et ont examiné leur dossier. Ils ont fouillé PubMed pour trouver des rapports de cas et en ont extrait des données. RÉSULTATS: Les chercheurs ont analysé sept nouveaux cas locaux et 30 anciens cas. Cette infection est similaire sur le plan clinique à d'autres formes de péritonite associée à la DP, dont le principal facteur de risque semble être l'exposition à un animal domestique. Les chats sont les plus en cause. On signale souvent un contact direct entre l'animal et le matériel (25 patients sur 37), mais il n'est pas nécessaire pour provoquer l'infection. Le traitement durait en moyenne 15 jours. Le taux de complications était faible, puisque seulement 11 % des patients ont dû faire retirer leur cathéter de DP. Aucun décès n'a été signalé. CONCLUSION: Les espèces de Pasteurella sont de rares causes de péritonite associée à la DP qu'on peut soigner par un traitement de deux semaines aux antibiotiques intrapéritonéaux. Ce traitement s'associe à une forte probabilité de sauvegarder le cathéter.
RESUMO
BACKGROUND: The purpose of this study was to evaluate the effect of foot problems on mental health in diabetic patients and their caregivers. METHODS: Diabetic patients (47 patients with and 49 patients without foot problems), and 21 caregivers of patients with foot problems, completed outcome surveys. Foot problems included ulcers (41 patients [87%]), osteomyelitis (9 patients [19%]), and Charcot foot (8 patients [17%]). RESULTS: In contrast with diabetic patients having no foot problems, diabetic patients with foot problems had, on average, significantly greater symptoms of diabetes (Diabetes Symptom Checklist-2 score), greater depression symptoms (Hospital Anxiety and Depression Scale [HADS]-Depression score), worse health-related quality of life (Medical Outcome Study Short Form 36 [SF-36]: Physical Component Summary score and 6 of 8 subscales), greater pain (Short-Form McGill Pain Questionnaire), and greater suicidal behavior (Suicidal Behaviors Questionnaire-Revised). There were no significant differences in alcohol use (mean Alcohol Use Disorder Identification Test score), anxiety (HADS-Anxiety score), or SF-36 Mental Component Summary score between patients with and without foot problems. Caregivers had marked caregiver burden (average Montgomery Caregiver Burden Assessment score) and frequently had mild to moderate depression and anxiety. CONCLUSIONS: Foot problems are significantly associated with mental health symptoms in diabetic patients and caregivers. This may affect treatment in the foot clinic, outcome, and quality of life.

Bacteria belonging to the Streptococcus anginosus group (Streptococcus intermedius, Streptococcus constellatus and Streptococcus anginosus) are capable of causing serious pyogenic infections, with a tendency for abscess formation. The present article reports a case of S anginosus group pyomyositis in a 47-year-old man. The pathogen was recovered from one of two blood cultures obtained from the patient, but speciation was initially not performed because the organism was considered to be a contaminant (viridans streptococci group). The diagnosis was ultimately confirmed using 16S ribosomal DNA sequencing of purulent fluid obtained from a muscle abscess aspirate. The present case serves to emphasize that finding even a single positive blood culture of an organism belonging to the S anginosus group should prompt careful evaluation of the patient for a pyogenic focus of infection. It also highlights the potential utility of 16S ribosomal DNA amplification and sequencing in direct pathogen detection from aspirated fluid in cases of pyomyositis in which antimicrobial therapy was initiated before specimen collection.
Les bactéries qui appartiennent au groupe Streptococcus anginosus (streptocoques intermedius, constellatus et anginosus) peuvent causer de graves infections à pyogènes qui ont tendance à former des abcès. Le présent article contient un cas de pyomyosite du groupe S anginosus chez un homme de 47 ans. Le pathogène a été décelé récupéré dans une des deux cultures sanguines prélevées sur le patient, mais au départ, la spéciation n'a pas été effectuée parce que l'organisme était considéré comme un contaminant (groupe de streptocoques viridians). Le diagnostic a finalement été confirmé au moyen du séquençage de l'ADN ribosomal 16S du fluide purulent obtenu dans l'aspirat d'un abcès musculaire. Le présent cas fait ressortir le fait que la détection d'une seule culture sanguine positive dans un organisme appartenant au groupe S anginosus devrait susciter une évaluation attentive du patient afin de trouver un foyer d'infection à pyogènes. Il fait également ressortir l'utilité potentielle de l'amplification et du séquençage de l'ADN ribosomal 16S pour la détection directe d'un pathogène dans le fluide aspiré en cas de pyomyosite lorsque le traitement aux antibiotiques a commencé à être administré avant le prélèvement.
RESUMO
Foot infections are a common and serious problem in persons with diabetes. Diabetic foot infections (DFIs) typically begin in a wound, most often a neuropathic ulceration. While all wounds are colonized with microorganisms, the presence of infection is defined by ≥2 classic findings of inflammation or purulence. Infections are then classified into mild (superficial and limited in size and depth), moderate (deeper or more extensive), or severe (accompanied by systemic signs or metabolic perturbations). This classification system, along with a vascular assessment, helps determine which patients should be hospitalized, which may require special imaging procedures or surgical interventions, and which will require amputation. Most DFIs are polymicrobial, with aerobic gram-positive cocci (GPC), and especially staphylococci, the most common causative organisms. Aerobic gram-negative bacilli are frequently copathogens in infections that are chronic or follow antibiotic treatment, and obligate anaerobes may be copathogens in ischemic or necrotic wounds. Wounds without evidence of soft tissue or bone infection do not require antibiotic therapy. For infected wounds, obtain a post-debridement specimen (preferably of tissue) for aerobic and anaerobic culture. Empiric antibiotic therapy can be narrowly targeted at GPC in many acutely infected patients, but those at risk for infection with antibiotic-resistant organisms or with chronic, previously treated, or severe infections usually require broader spectrum regimens. Imaging is helpful in most DFIs; plain radiographs may be sufficient, but magnetic resonance imaging is far more sensitive and specific. Osteomyelitis occurs in many diabetic patients with a foot wound and can be difficult to diagnose (optimally defined by bone culture and histology) and treat (often requiring surgical debridement or resection, and/or prolonged antibiotic therapy). Most DFIs require some surgical intervention, ranging from minor (debridement) to major (resection, amputation). Wounds must also be properly dressed and off-loaded of pressure, and patients need regular follow-up. An ischemic foot may require revascularization, and some nonresponding patients may benefit from selected adjunctive measures. Employing multidisciplinary foot teams improves outcomes. Clinicians and healthcare organizations should attempt to monitor, and thereby improve, their outcomes and processes in caring for DFIs.

BACKGROUND: Lower extremity complications are a major cause of morbidity and mortality in patients with end-stage renal disease (ESRD) and diabetes mellitus. Patient education programs may decrease the risk of diabetic foot complications. METHODS: A preventive program was instituted, consisting of regular assessments by a foot care nurse with expertise in foot care and wound management and patient education about foot care practices and footwear selection. Medical records were reviewed and patients were examined. A comparison was made with data about patients from a previous study done from this institution prior to development of the foot care program. RESULTS: Diabetic subjects more frequently had weakness of the left tibialis anterior, left tibialis posterior, and left peroneal muscles than non-diabetic subjects. A smaller percentage of diabetic subjects had sensory neuropathy compared with the previous study from 5years earlier, but a greater percentage of diabetic subjects had absent pedal pulses in the current study. The frequency of inadequate or poor quality footwear was less in the current study compared with the previous study. CONCLUSIONS: The current data suggest that a foot care program consisting of nursing assessments and patient education may be associated with a decrease in frequency of neuropathy and improved footwear adequacy in diabetic patients with ESRD.

Infection prevention and control measures are used to contain outbreaks of carbapenemase-producing Enterobacteriaceae. We report the absence of transmission of Klebsiella pneumoniae carrying New Delhi metallo-ß-lactamase and oxacillinase-48 genes among 19 screened contacts of an index case after 14 months of routine practices in a long-term care facility.
RESUMO
INTRODUCTION: Healing time for neuropathic planter foot ulcers (NPFUs) in persons with diabetes may be reduced through use of non-removable fiberglass total contact casting (F-TCC) compared with removable cast walkers (RCWs), although the evidence base is still growing. RESEARCH DESIGN AND METHODS: We conducted a rapid review and systematically searched for, and critically assessed, randomized controlled trials (RCTs) that compared the efficacy of F-TCC versus RCW, focusing on the time to ulcer healing in adult persons (18+ years) with NPFUs and type 1 or type 2 diabetes. We meta-analysed the mean differences and associated 95% CIs using an inverse variance, random-effects model. We also conducted a trial sequential analysis (TSA) to assess if the available evidence is up to the required information size for a robust conclusion. We assessed and quantified statistical heterogeneity between the included studies using the I2 statistic. RESULTS: Out of 102 retrieved citations, five RCTs met the eligibility criteria. Participants' inclusion in relation to stage of ulcer was highly variable as was peripheral neuropathy complicating comparisons. F-TCC appeared to present a shorter ulcer healing time (-5.42 days, 95% CI -9.66 days to -1.17 days; I2 9.9%; 5 RCTs; 169 participants) compared with RCW. This finding was supported by the TSA. CONCLUSIONS: There is limited evidence from RCTs to suggest that F-TCC has a shorter ulcer healing time compared with RCW among adults with diabetic NPFUs. Properly designed and conducted RCTs are still required for a stronger evidence base.

Blastomyces dermatitidis, a thermally dimorphic fungus endemic to areas of North America, causes a granulomatous infection which may affect any organ system. Since limited clinical data exist about pediatric blastomycosis, we conducted a retrospective review of medical records of pediatric patients with a laboratory-confirmed diagnosis of blastomycosis treated during a 30-year period at a tertiary care center. Thirty-four pediatric patients with blastomycosis were identified (20 [59%] male), with a mean age at diagnosis of 10 ± 5 years. Two patients were immunocompromised. Pulmonary disease was noted in 27 (79%) patients, and extrapulmonary disease was found in 13 (38%) patients (concurrent pulmonary and extrapulmonary disease, six patients), including five cases of central nervous system (CNS) disease. Delay in diagnosis was greater with extrapulmonary or central nervous system infections as compared with pulmonary blastomycosis. All patients received antifungal chemotherapy, with 19 (56%) patients receiving amphotericin B as initial therapy for 27.5 ± 17 days. Five patients required treatment in the intensive care unit. One patient died of non-Hodgkins lymphoma. Blastomycosis may occur in healthy children, including very young infants. Due to the frequency of extra-pulmonary disease, diagnosis may be difficult and frequently delayed, especially in cases of CNS infection.
