RESUMO
AIMS: To conduct a multicentre observational study to describe management of foot infections in diabetes in the out-patient setting in Italy. PATIENTS AND METHODS: Ten centres equally distributed nationwide were asked to collect, by means of a spreadsheet (Access/Excel Microsoft program), data concerning 30 consecutive diabetic patients with foot infections deemed suitable for antibiotic treatment in the out-patient setting. Centres with > or = 5 years' experience of out-patient management were selected. Data from 271 consecutive patients treated as out-patients were collected and analysed by the central coordinator. Statistical analysis was performed using the SPSS statistical software package. RESULTS: Lesions were mainly located at the toes and midfoot (33.6 and 30.2%, respectively); 63 (23.2%) patients had multiple ulcers. Seventy (25.8%) patients also had concomitant osteomyelitis. Three hundred and four pathogens, including Gram-positive and Gram-negative aerobes and anaerobes, were isolated in 219/271 patients (80.8%) by culturing debrided tissue (71.2%) or purulent material (28.8%). Infections were polymicrobial in 33.8% of patients. The most common pathogens were Staphylococcus aureus (27.3%) and Pseudomonas spp. (20.4%); enterobacteriaceae, enterococci, streptococci and anaerobes accounted for 11.5, 7.6, 6.9 and 1.9%, respectively. Antibiotics were frequently administered by parenteral route and frequently in combination. Piperacillin/tazobactam was the parenteral antibiotic most frequently utilized (21.1%). Cure/improvement was observed in 93.4% of patients. CONCLUSIONS: Foot ulcers in diabetes are common and serious; the aetiology is often polymicrobial, often including S. aureus and Pseudomonas spp. Treatment in the out-patient setting is safe and effective, and penicillins together with beta-lactamase inhibitors and fluoroquinolones are the most frequent choice.

OBJECTIVE: To assess the relationship of waist circumference and weight/height ratio with height, and their association with components of the metabolic syndrome, in Type 2 diabetic patients. DESIGN: multicenter cross-sectional survey on a cohort enrolled in a prospective observational study. SUBJECTS: 13,232 patients (6816 women and 6416 men) with Type 2 diabetes, not currently affected by macrovascular complications. MEASUREMENTS: height, weight, waist and hip circumference, waist/hip and waist/height ratios. RESULTS: waist circumference was significantly correlated with height after adjustment for potential confounders (adjusted r=0.19 and 0.23 in women and men, respectively), while waist/height ratio showed an inverse correlation with height (r=-0.14 and -0.15, respectively). Elevated waist/height ratio was more predictive of hypertension and hypertriglyceridemia, than waist circumference or waist/hip ratio. CONCLUSIONS: Waist circumference is correlated with height; thresholds for waist circumference could need adjustment for height. Waist/height ratio, although inversely correlated with height, could be a better predictor of abnormalities associated with abdominal adiposity than waist circumference alone.
