Leprosy is a chronic infectious disease that has a slow evolution and is characterized by dermatoneurological involvement. The health challenges surrounding this disease are closely related to the stigma that results from the physical disabilities it causes. This is due to its high rate of late diagnosis and the peculiar deformities that occur in its advanced stage. Evaluate the clinical and epidemiological aspects of patients with plantar lesions who were treated for leprosy in a dermatology referral unit. This is a cross-sectional exploratory field study that was conducted at the Reference Center in Tropical Dermatology and Venereology Alfredo da Matta (FUHAM), in Manaus, Amazonas, Brazil. We evaluated 36 patients with disabilities as a result of leprosy and who had plantar lesions. The most common ulcer site was the medial region of the plantar surface, which presented dryness and maceration with yellowish seropurulent exudate, fibrinous tissue and grade 2 depth. The study made it possible to observe the evolution of plantar ulcers resulting from the disease process, then evaluate them and discuss recommendations regarding the treatment and prevention of this type of physical disability.

Evans Syndrome (ES) is a rare autoimmune disorder characterized by the simultaneous occurrence of immune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA). Thrombotic complications in ES patients are uncommon, particularly involving Buerger\'s Disease (BD). We report a case of a 49-year-old male with ES and a history of diabetes and heavy smoking, presenting with a necrotic wound on his right great toe. Diagnostic evaluations revealed severe stenosis and thrombosis in the lower limb arteries, diagnosed as BD. The patient underwent successful popliteal-tibioperoneal artery bypass surgery and the subsequent disarticulation and revision of the distal phalanx, followed by the application of an acellular dermal matrix (ADM) to promote healing. Post-surgery, the patient showed significant improvement in blood flow and complete epithelialization without complications. This case highlights the importance of a multidisciplinary approach to managing complex wounds in ES patients, suggesting potential treatment pathways for future cases involving BD.

Diabetes prevalence continues to increase worldwide, which has led to a rising incidence of diabetes-related foot infections (DFIs). There is significant local variation in the microbiology of DFIs, and Pseudomonas spp. is suggested to be more prevalent in subtropical climates. The aim of this study was to investigate the local microbiological findings in patients admitted to the hospital with DFIs. This retrospective study analysed data from all adult patients diagnosed with diabetes and admitted to the hospital for the treatment of a DFI between 1 January 2021 and 31 December 2022. Both superficial wound swabs and tissue cultures were included. The Infectious Diseases Society of America classification system was used to categorise the severity of the DFI. Patient characteristics and demographics were analysed using descriptive statistics. One hundred fifty-one episodes of care were included. Most of the DFIs were classified as moderate infections 101/151 (67%). The most commonly isolated microorganism was Staphylococcus aureus (33%) followed by normal skin flora (11%) and β-haemolytic streptococci (7%). P. aeruginosa was isolated more commonly in those with chronic DFIs (10%) compared to those with acute DFIs (2%). Despite the frequent identification of S. aureus, 83% of patients received an antipseudomonal antibiotic. The introduction of multidisciplinary DFI rounds should be considered.

BACKGROUND: Diabetes related foot ulcer (DFU) is a leading cause of impaired quality of life, disability, hospitalisation, amputation and mortality in people with diabetes. It is therefore critical that podiatrists across all settings, including community settings, are confident and capable of providing care for diabetes-related foot complications. This study aims to describe current practice, confidence and anxiety levels of community podiatrists in the management of patients with foot ulceration. Furthermore, current barriers to service provision and interest in future educational opportunities will also be explored.
METHODS: An online cross-sectional survey was distributed to Australian community podiatrists. Descriptive variables including gender, age, professional experience, practice location and practise setting were elicited. A modified competitive State Anxiety Inventory-2 (CSAI-2) was utilised to measure anxiety related to managing a foot ulcer. Other questions included a combination of multiple choice and open-ended free-text responses relating to assessment, confidence and referral pathways.
RESULTS: One hundred and twenty-two Australian community-based podiatrists responded to the survey. A variety of ulcer sizes and complexity were reported to be managed in community settings. Confidence in DFU management was high in most manual skill domains including: stabilisation of the foot (85.7%, standard deviation [SD] 17.42), scalpel control (83.0%, SD 20.02), debridement with a scalpel (82.7%, SD 18.19) and aseptic technique (81.0%, SD 18.62, maintaining integrity of healthy tissue (77.3%, SD 21.11), removal of appropriate tissue (75.6%, SD 22.53), depth of ulceration (73.7%, SD 23.99) and ability to manage messy wounds (69.1%, SD 26.04). Curette debridement had substantially lower levels of reported confidence (41.0%, SD 34.24). Performance anxiety was low with somatic and cognitive anxiety of 6/24 and 3/8 on the CSAI-2, respectively.
CONCLUSIONS: Community podiatrists are managing foot ulcers of varying size and complexity. Confidence and anxiety do not pose a barrier to care. Adherence to wound assessment clinical guidelines is low and confidence with the use of curette was sub-optimal. Further educational programs may overcome these barriers and support shared models of care between community and acute podiatry services.

BACKGROUND: Therapeutic offloading devices, including insoles, shoes, and other orthoses, are some of the most commonly used interventions to treat or prevent diabetic foot ulceration. Custom-made offloading devices are increasingly used to offset the development of foot ulcers. However, whether these devices are more effective than prefabricated standard offloading devices is uncertain. Therefore, this systematic review collates and examines evidence on the efficacy of custom-made offloading devices in preventing foot ulcer incidence and recurrence in people diagnosed with diabetes.
METHODS: Five scientific databases were searched, covering 2011-2023. Initial searches and screening were carried out independently by two researchers. Studies meeting the inclusion criteria were further examined through additional screenings, and critical appraisal. Data relevant to the review aims were extracted and analysed within a narrative synthesis.
RESULTS: Of the 1,715 articles found in the initial searches, nine papers were found to meet inclusion criteria and were included in the review. The evidence shows that custom-made offloading devices are likely to be more effective for reducing or preventing diabetic foot ulcers than standard offloading devices. However, due to a lack of data it remains uncertain whether custom-made offloading devices are more cost-effective for preventing ulceration compared to standard insoles. Likewise, due to measurement heterogeneity between studies and lack of data, it is unclear whether adherence is higher in users of custom-made offloading devices, and whether such devices deliver significantly greater reductions in peak pressure as compared to standard offloading devices.
CONCLUSIONS: Custom-made offloading devices are more effective than standard devices for preventing diabetic foot ulceration, and we recommended their use when feasible; however, there remains uncertainty regarding their cost-effectiveness compared to standard insoles and offloading devices.

Diabetic foot ulcer (DFU), characterized by high recurrence rate, amputations and mortality, poses a significant challenge in diabetes management. The complex pathology involves dysregulated glucose homeostasis leading to systemic and local microenvironmental complications, including peripheral neuropathy, micro- and macro-angiopathy, recurrent infection, persistent inflammation and dysregulated re-epithelialization. Novel approaches to accelerate DFU healing are actively pursued, with a focus on utilizing exosomes. Exosomes are natural nanovesicles mediating cellular communication and containing diverse functional molecular cargos, including DNA, mRNA, microRNA (miRNA), lncRNA, proteins, lipids and metabolites. While some exosomes show promise in modulating cellular function and promoting ulcer healing, their efficacy is limited by low yield, impurities, low loading content and inadequate targeting. Engineering exosomes to enhance their curative activity represents a potentially more efficient approach for DFUs. This could facilitate focused repair and regeneration of nerves, blood vessels and soft tissue after ulcer development. This review provides an overview of DFU pathogenesis, strategies for exosome engineering and the targeted therapeutic application of engineered exosomes in addressing critical pathological changes associated with DFUs.

Diabetic foot ulcer is the most common complication causing lots of admissions among diabetic patients. Understanding patients\' level of foot self-care knowledge, practice and associated factors is important for planning interventions to control and prevent diabetic foot complications. This study aimed to assess the level of knowledge and practice of foot self-care among diabetic patients attending diabetic clinics in The Gambia. Two hundred and seventeen patients attending diabetic clinics in two public hospitals were selected using a successive sampling technique. Data were collected using a validated interviewer-administered questionnaire. Descriptive statistics were used to summarize the demographic and clinical data. Multivariate logistic regression was used to identify factors associated with foot self-care knowledge and practice. The findings showed a poor level of foot self-care knowledge (n = 114; 52.5%) and practice (n = 149; 68.7%). Patients\' educational level was statistically significantly association with diabetic foot self-care knowledge (p = 0.02). Diabetic foot ulcer history (aOR = 0.23, 95% CI: 0.08-0.63; p < 0.001), diabetic hospitalization (aOR = 2.41, 95% CI: 1.23-4.75, p = 0.01) and diabetic foot care education (aOR = 2.65, 95% CI: 1.39-5.06, p < 0.001) were statistically significantly associated with foot self-care practice. The poor diabetic foot self-care knowledge and practice among these patients emphasize the need for a diabetic health education program in these clinics.

BACKGROUND: The field of medical grade footwear is dynamic. Originally, a field where individual knowledge, expertise and skills determined the footwear and its outcomes, now becoming a more evidence-based and data-driven field with protocols and systems in place to create appropriate footwear. However, scientific evidence concerning medical grade footwear is still limited. Evidently, all stakeholders, from patients to pedorthists to rehabilitation physicians, will profit from a larger evidence-base in this field. A widely supported research agenda is an essential first step to advance and facilitate new knowledge.
METHODS: We formed a multidisciplinary team and followed the methodology from Dutch medical societies for the development of a research agenda on medical grade footwear. This consisted of seven steps: (1) inventory of relevant questions with users and professionals; (2) analyses of responses; (3) analyses of existing knowledge and evidence; (4) formulating research questions; (5) prioritising research questions by users and professionals; (6) finalising the research agenda and (7) implementing the research agenda.
RESULTS: In phase 1, 109 participants completed a survey, including 50% pedorthists, 6% rehabilitation physicians and 3% users. Participants provided 228 potential research questions. In phases 2-4, these were condensed to 65 research questions. In phase 5, 152 participants prioritised these 65 research questions, including 50% pedorthists, 13% rehabilitation physicians and 9% users. In phase 6, the final research agenda was created, with 26 research questions, categorised based on the International Classification of Functioning Disability and Health \'process description assistive devices\'. In phase 7, an implementation meeting was held with over 50 stakeholders (including users and professionals), resulting in seven applications for research projects based on one or more research questions from the research agenda.
CONCLUSIONS: This research agenda structures and guides knowledge development within the field of medical grade footwear in the Netherlands and elsewhere. We expect that this will help to stimulate the field to tackle the research questions prioritised and with that to advance scientific knowledge in this field.

Objective: This prospective cohort study aimed to determine the relationship between serum vitamin C, D, and zinc on foot wound healing and compare time to healing in individuals who are deficient versus those who have adequate levels. Approach: One hundred adults with foot wounds were recruited from Blacktown high-risk foot service with a follow-up period of 12 months. Serum vitamin C, D, and zinc as well as routine baseline blood testing was undertaken. Wounds were measured using a three-dimensional wound camera and classified using the Wound Ischemia and Foot Infection system at regular intervals. Results: Vitamin C deficiency was present in 75% of participants, 50% had vitamin D deficiency, and 38% had zinc deficiency. Diabetes was present in 91% of participants, and 50% had a history of previous amputation. Wound chronicity (p = 0.03) and toe pressures (p = 0.04) were predictive of wound healing. Serum vitamin C, D, and zinc were not associated with significant differences in wound healing or time to wound healing. Innovation: Deficiencies in vitamin C, D, and zinc were highly prevalent in participants with active foot ulceration. Wound chronicity was predictive of healing outcomes, highlighting the importance of rapid access to best practice care. Conclusion: This cohort had high deficiency rates of vitamin C, D, and zinc consistent with previous literature; however, there was no relationship between these deficiencies and wound healing or time to heal. Large randomized controlled trials are required to comprehensively determine if adequate levels of these nutrients improve wound healing outcomes.

AIMSWERNER SYNDROME IS A RARE PREMATURE AGEING AUTOSOMAL RECESSIVE DISORDER CAUSED BY PATHOGENIC VARIANTS IN THE WRN GENE. PEOPLE WITH WERNER SYNDROME MAY DEVELOP DIABETES MELLITUS. CHRONIC FOOT ULCERATION IS SEEN, WITH SOME CHARACTERISTICS OVERLAPPING WITH DIABETIC FOOT DISEASE. HOWEVER, THE CLINICAL COURSE OF THE ULCERATION IS ATYPICAL OF DIABETIC FOOT DISEASE. WE PRESENT FOUR SIBLINGS FROM AN IRISH TRAVELLER FAMILY WITH WERNER SYNDROME TO HIGHLIGHT THE COMPLEXITY OF THIS CONDITION. THE IRISH TRAVELLER POPULATION ARE AN INDIGENOUS, ENDOGAMOUS POPULATION IN WHICH CONSANGUINITY IS COMMON. AS A RESULT, RARE AUTOSOMAL RECESSIVE DISORDERS ARE PREVALENT AMONG THIS POPULATION: .
METHODS: We describe our experience managing the complex foot disease seen in all four siblings. Foot complications present in the siblings include painful peripheral neuropathy, chronic foor ulceration, underlying osteomyelitis and acral melanoma.
RESULTS: The cases are described individually, with a particular focus on the complex foot disease associated with the condition.
CONCLUSIONS: Although the siblings attend a diabetic foot clinic, we suggest that the combination of clinical features seen in these cases is unique to Werner syndrome and warrants the title \'Werner Syndrome\' (rather than \'Diabetic\') foot.
