Diabetic footfoot ulcer (DFU) is a serious complication of diabetes mellitus, and possibly the major morbidity of the diabetic foot. It is the most common foot injury in diabetic patients and can lead to lower-extremity amputation. Management of DFU requires a systematic knowledge of the major risk factors for amputation, frequent routine evaluation, scrupulous preventive maintenance, and correction of peripheral arterial insufficiency. Carboxytherapy refers to the subcutaneous injection of CO2 to improve the microcirculation and promote wound-healing by stimulating the microcirculation...

BACKGROUND Intracardiac abscesses are an unusual occurrence in developed countries. With the increase in use of implantable cardiac devices, the increase use of and advancements in antibiotics, and the longevity of patients with cardiac devices, one may expect an increase in such infections; however, case reports are rare. We are presenting a case in which hematogenous dissemination of methicillin-sensitive Staphylococcus aureus (MSSA) infection from a lower extremity diabetic ulcer propagated into an infected pacemaker lead and ultimately an intracardiac abscess of the right atrium...

Diabetic patients are more prone to the development of foot ulcers, because their underlying tissues are exposed to colonization by various pathogenic organisms. Hence, biofilm formation plays a vital role in disease progression by antibiotic resistance to the pathogen found in foot infections. The present study has demonstrated the correlation of biofilm assay with the clinical characteristics of diabetic foot infection. The clinical characteristics such as the ulcer duration, size, nature, and grade were associated with biofilm production...

Diabetic foot ulcers may result in loss of an extremity and may even lead to mortality. The use of comprehensive foot care programs which include early screening and evaluation of problems, foot care education, preventive therapy and referral to specialists has been shown to reduce amputation rates by 49-85 [percent]. A 51-year-old woman with Type 2 diabetes under surveillance for nine months was referred from the emergency department. She presented with an entirely inflamed right foot with ulcer covering two-thirds proximal of the foot for 30 days' duration...

Diabetic foot ulcer treatment currently focuses on targeting bacterial biofilms, while dismissing fungi. To investigate this, we used an in vitro biofilm model containing bacteria and fungi, reflective of the wound environment, to test the impact of antimicrobials. Here we showed that while monotreatment approaches influenced biofilm composition, this had no discernible effect on overall quantity. Only by combining bacterium- and fungus-specific antibiotics were we able to decrease the biofilm bioburden, irrespective of composition...

Diabetic foot ulcers (DFUs) are a serious and common problem in patients with diabetes mellitus and constitute one of the major causes of lower extremity amputation. The microbiological profile of DFUs depends on the acute or chronic character of the wound. Aerobic gram-positive cocci are the predominant organisms isolated from DFUs. Diabetic foot biopsies from patients admitted to the Angiology and Vascular Surgery Hospital of the Northeast, in Reynosa, Tamaulipas from December 2011 to April 2016 were analyzed...
