Skin and soft tissue infections (SSTIs), and particularly diabetic-related foot infections (DFI), present diagnostic and therapeutic complexities, often leading to severe complications. This study aims to evaluate the in vitro efficacy of cefditoren and amoxicillin/clavulanic acid against typical DFI pathogens. Clinical samples from 40 patients with mild SSTIs were analyzed, revealing a predominance of Staphylococcus spp. and Streptococcus spp. species. Cefditoren exhibited activity against 90% of isolates, with superior potency over amoxicillin/clavulanic acid. These findings underscore the utility of cefditoren in empirical treatment of DFI, although a larger sample size would be desirable for further validation.

AIMS: To analyse the risk of reulceration caused by the transfer of lesions in patients with diabetes, undergoing resection of at least one metatarsal head. METHODS: A total of 119 patients with diabetes from the Diabetic Foot Unit (Complutense University, Madrid, Spain), who underwent resection of at least one metatarsal head were analysed prospectively from November 2006 to December 2011 to assess reulceration in the other metatarsal head. RESULTS: Seven patients were excluded for being subjected to a pan-metatarsal head resection and 11 patients dropped out. During a median follow-up period of 13.1 months (interquartile range 6.1-22.8 months), 41% of patients suffered from reulcerations. Reulceration frequency in patients operated on the 1st, 2nd, 3rd, 4th, 5th and several metatarsal heads was 9 (69%), 8 (44%), 12 (52%), 2 (25%), 6 (19%) and 4 (50%) events, respectively. The Cox regression model showed hazard ratios that were significant for the location of the metatarsal resection. The first metatarsal showed the highest risk for reulceration (hazard ratio 3.307; 1.472-7.430) and the fifth metatarsal showed the lowest risk (hazard ratio 0.339; 0.138-0.832). CONCLUSIONS: Reulceration is a frequent event following resection of a metatarsal head and should be regarded as an implicit complication of the intervention. The location of the resection determines the risk of reulceration, which is highest for patients operated on the first metatarsal head and lowest for patients operated on the fifth metatarsal head.

BACKGROUND: Charcot neuroarthropathy is a severe complication in the feet of patients with diabetes, which can lead to a major amputation. Osteomyelitis and surgery for osteomyelitis have been reported as trigger mechanisms of developing Charcot neuroarthropathy. However, the development of acute Charcot neuroarthropathy triggered by osteomyelitis during conservative antibiotic treatment is not well outlined in the medical literature. CASE REPORTS: Two patients apparently developed mid and rear foot Charcot neuroarthropathy, which was clinically suspected while being treated with antibiotics for osteomyelitis. One of them presented osteomyelitis of the navicular bone and subsequently developed acute Charcot neuroarthropathy of the tarsometatarsal joints. The other presented calcaneal osteomyelitis with pathological fracture and developed Charcot neuroarthropathy of the transverse tarsal joint. No offloading had been implemented in either case. A major amputation had been indicated in both cases in their teaching hospitals. Limb salvage was achieved in both cases by means of surgery, culture-guided post-operative antibiotics, intraosseus instillation of super-oxidized solution, bed rest before placing a total contact cast and stabilization of the unstable foot with a total contact cast with an opening for checking the healing course and to detect any complications. The mechanisms of the development of acute Charcot neuroarthropathy in a patient with osteomyelitis are discussed. CONCLUSIONS: Osteomyelitis in the feet of patients with diabetes and neuropathy may trigger the development of acute Charcot neuroarthropathy. Fractures and dislocated joints may subsequently become infected from the index focus, producing a severe infected and unstable foot that may require a major amputation. Limb salvage can be achieved in specialized departments.

We aimed to identify if any differences existed in spatiotemporal parameters during gait among different densities of rocker soles in patients with a history of neuropathic ulcerations and the differences in comfort between shoe conditions. This study was a cross-sectional study of 24 patients with diabetes and a history of neuropathic diabetic foot ulcers (DFUs). Spatiotemporal parameters (duration of stance phase (ms), stride length (cm), and step velocity (m/s)) were analyzed in barefoot, semirigid outsole, and rigid outsole footwear conditions. A dynamic pressure measurement system (Footscan® system, RSscan International, Belgium) was used to assess shoe conditions. We also analyzed differences in comfort between the shoe conditions using a visual analog scale. A Wilcoxon test for paired samples was used to assess gait differences. Result showed that a rigid outsole causes changes in the subphases of the stance phase (p < 0.001; Cohen d = 0.6) compared to a semirigid outsole. Stride length (p < 0.001; Cohen d = 0.66) and step velocity were significantly longer (p < 0.001; Cohen d = 2.03) with the use of rigid outsole footwear. A rigid rocker sole reduces the time of the stance phase, in addition to increasing the stride length and velocity of step in patients with a previous history of DFUs.

AIMS: To evaluate the factors that predict reulceration beneath the hallux in people with a history of diabetic foot ulceration. METHODS: A prospective study conducted between January 2012 and December 2014 was performed in a diabetic foot unit to assess the risk factors associated with hallux reulceration. Sixty patients with diabetic neuropathy and a history of previous ulcer were consecutively included. Sociodemographic factors and comorbidities plus the biomechanical and radiographic factors were obtained. Follow-up on participants was conducted every month, and they wore offloading therapeutic footwear and custom-made insoles. Hallux reulceration during the follow-up period was assessed as the main outcome measure in the study. RESULTS: Patients were followed up during 29 (14.2-64.4) months. Twenty-nine patients (52%) developed a new ulceration: 9 patients (31%) in the hallux and 20 (69%) in other locations. Functional hallux limitus (p = 0.005, 95% CI (2.097-73.128), HR 12.384) and increased body mass index (p = 0.044, 95% CI (1.003-1.272), HR 1.129) were associated with the hallux ulceration-free survival time in the multivariate Cox model. CONCLUSIONS: Obesity and the presence of functional hallux limitus increase the probability of developing hallux reulceration in patients with diabetic neuropathy and a history of ulcers.

AIMS: To stratify the ulceration risk according to the foot morphology in people with diabetes and a history of forefoot neuropathic ulceration. METHODS: A cross-sectional study was performed on 139 neuropathic individuals with diabetes and previous forefoot ulcers between January 2012 and February 2014. Foot position of the participants was evaluated by using the foot-posture index. A multivariate analysis adjusted for confounding variables was performed with the ulceration risk factors that were found in the univariate analysis. RESULTS: Two hundred and fifty-eight feet were analysed, 104 (40.3%) feet had a history of ulceration on the forefoot and 154 (59.7%) feet had no previous ulceration. Two positive tests of neuropathy (p<0.001; CI[1.961-6.249] OR 3.500), presence of deformities (p=0.043; CI[1.020-3.599] OR 1.916) and foot type (p=0.039) showed an association with ulceration risk in multivariate analyses. Pronated feet showed a higher risk of ulceration than supinated feet (p=0.011; CI[1.253-5.708] OR 2.675), while significant differences between neutral and supinated feet were not found (p=0.221; CI[0.719-2.753] OR 1.476). CONCLUSIONS: A pronated foot has a higher risk of ulceration on the forefoot in neuropathic people with deformities and diabetes mellitus. Foot type should be evaluated in people at risk of ulceration.
