Selected AbstractsSystematic review of methods to diagnose infection in foot ulcers in diabetesDIABETIC MEDICINE, Issue 4 2006S. O'Meara Abstract Aim, To undertake a systematic review of the diagnostic performance of clinical examination, sample acquisition and sample analysis in infected foot ulcers in diabetes. Methods, Nineteen electronic databases plus other sources were searched. To be included, studies had to fulfil the following criteria: (i) compare a method of clinical assessment, sample collection or sample analysis with a reference standard; (ii) recruit diabetic individuals with foot ulcers; (ii) present 2 × 2 diagnostic data. Studies were critically appraised using a 12-item checklist. Results Three eligible studies were identified, one each on clinical examination, sample collection and sample analysis. For all three, study groups were heterogeneous with respect to wound type and a small proportion of participants had foot ulcers due to diabetes. No studies identified an optimum reference standard. Other methodological problems included non-blind interpretation of tests and the time lag between index and reference tests. Individual signs or symptoms of infection did not prove to be useful tests when assessed against punch biopsy as the reference standard. The wound swab did not perform well when assessed against tissue biopsy. Semiquantitative analysis of wound swab might be a useful alternative to quantitative analysis. The limitations of these findings and their impact on recommendations from relevant clinical guidelines are discussed. Conclusion, Given the importance of this topic, it is surprising that only three eligible studies were identified. It was not possible to describe the optimal methods of diagnosing infection in diabetic patients with foot ulceration from the evidence identified in this systematic review. Diabet. Med. 23, 341,347 (2006) [source] Diabetic foot ulcer and multidrug-resistant organisms: risk factors and impactDIABETIC MEDICINE, Issue 7 2004A. Hartemann-Heurtier Abstract Aims The primary objective was to characterize factors allowing the colonization of diabetic foot wounds by multidrug-resistant organisms (MDRO), and the secondary objective was to evaluate the influence of MDRO colonization/infection on wound healing. Methods In 180 patients admitted to a specialized diabetic foot unit, microbiological specimens were taken on admission. Potential risk factors for MDRO-positive specimens were examined using univariate and multivariate analyses. Prospective follow-up data from 75 patients were used to evaluate the influence of MDRO colonization/infection on time to healing. Results Eighteen per cent of admission specimens were positive for MDRO. MDRO-positive status was not associated with patient characteristics (age, sex, type of diabetes, complications of diabetes), wound duration, or wound type (neuropathic or ischaemic). In the multivariate analysis, the only factors significantly associated with positive MDRO status on admission were a history of previous hospitalization for the same wound (21/32 compared with 48/148; P = 0.0008) or the presence of osteomyelitis (22/32 compared with 71/148; P = 0.025). In the longitudinal study of 75 wounds, MDRO-positive status on admission or during follow-up (6 months at least or until healing, mean 9 ± 7 months) was not associated with time to healing (P = 0.71). Conclusion MDROs are often present in severe diabetic foot wounds. About one-third of patients with a history of previous hospitalization for the same wound, and 25% of patients with osteomyelitis, had MDRO-positive specimens. This suggests that hygiene measures, or isolation precautions in the case of admission of patients presenting with these characteristics, should be aggressively implemented to prevent cross-transmission. Positive MDRO status is not associated with a longer time to healing.

To investigate the clinical course and epidemiology of V. vulnificus infection in Japan, we performed a retrospective questionnaire survey in which 1693 hospitals from all over Japan were surveyed, including advanced life saving emergency centers and dermatology institutions. Of the 1693 hospitals, we received answers from 1045. Ninety-four cases were confirmed as V. vulnificus infections during 1999 and 2003. Sixty-eight (72.3%) of the 94 patients had the septic type infection with a mortality rate of 75.0% (51/68 patients died). The prognosis of patients with the septic type was worse than that of the wound type (P < 0.001). V. vulnificus infections occurred from June to November and none occurred in winter. Many infections occurred in western Japan with the majority of infections (50/94) occurring in Kyushu. In particular, 43 infections occurred in marine coastal areas of the Ariake and Yatsushiro Seas, which have many tidelands. Seventy-seven of 89 patients (86.5%) had liver function impairment as an underlying disease, and 53 (59.6%) had liver cirrhosis, of whom nine (10.1%) suffered from liver cancer. The incidence of V. vulnificus infection was different according to districts. Geographic and climatic factors also contributed to the occurrence of V. vulnificus infection. [source] A Clinical Review of Infected Wound Treatment with Vacuum Assisted Closure® (V.A.C.®) Therapy: Experience and Case SeriesINTERNATIONAL WOUND JOURNAL, Issue 2009Allen Gabriel ABSTRACT Over the last decade Vacuum Assisted Closure® (KCI Licensing, Inc., San Antonio, TX) has been established as an effective wound care modality for managing complex acute and chronic wounds. The therapy has been widely adopted by many institutions to treat a variety of wound types. Increasingly, the therapy is being used to manage infected and critically colonized, difficult-to-treat wounds. This growing interest coupled with practitioner uncertainty in using the therapy in the presence of infection prompted the convening of an interprofessional expert advisory panel to determine appropriate use of the different modalities of negative pressure wound therapy (NPWT) as delivered by V.A.C.® Therapy and V.A.C. Instill® with either GranuFoamÔ or GranuFoam SilverÔ Dressings. The panel reviewed infected wound treatment methods within the context of evidence-based medicine coupled with experiential insight using V.A.C.® Therapy Systems to manage a variety of infected wounds. The primary objectives of the panel were 1) to exchange state-of-practice evidence, 2) to review and evaluate the strength of existing data, and 3) to develop practice recommendations based on published evidence and clinical experience regarding use of the V.A.C.® Therapy Systems in infected wounds. These recommendations are meant to identify which infected wounds will benefit from the most appropriate V.A.C.® Therapy System modality and provide an infected wound treatment algorithm that may lead to a better understanding of optimal treatment strategies.
