Background. The inactive stage of the diabetic Charcot arthropathy foot (CA) is characterised by fixed foot deformities and an absence of inflammation. However, it remains unclear if the shape of the foot and its biomechanics change during long-term follow-up. Aim. To evaluate changes in loading distribution of the affected foot, in patients with inactive CA, during long-term follow-up. Materials and methods. Twenty seven patients with unilateral inactive CA (19 females, 8 males) were studied. Computer pedography (emed AT, novel gmbh) was performed and baseline and the last studies were analysed. Maximal peak pressures (PP) were obtained for the first and the last studies and the percentage of the PP change was calculated for the total follow-up period and for periods: 24 months, 2448 months, 48 months. Results. PP increased: under the hallux 50%; 1st metatarsal30.7%; 2nd toe20%; 2nd toe6%; midfoot9%. PP decreased under 35 toes up to 67%. Significant changes at the first period were found under 35 toes only (62%). The increase in loading under the other parts of the foot appeared at 24 months; however, these changes became significant between 24 and 48 months and peaked after 48 months of follow-up. The maximal increase of PP was noticed under the hallux, the 2nd toe, metatarsals 13 and the midfoot. Conclusions. We revealed the gradual redistribution of PP, under the different parts of the foot, in patients with inactive CA. This redistribution reflects changes in the shape of the affected foot. The loading increased under the hallux, the 2nd toe and the corresponding metatarsals, 3rd metatarsal and midfoot, and decreased under the 35 toes. These changes increased during the follow-up, becoming more pronounced after 4 or more years. Our data may be useful for constructing custom-made footwear for patients with CA.

AIMS: To determine the prevalence of painful diabetic neuropathy (PDN), to evaluate the composition and efficacy of pharmacotherapy and to develop a differential algorithm for symptomatic treatment of PDN. MATERIALS AND METHODS: 4494 outpatient subjects participated in this study. Severity of pain syndrome was assessed with DN4 question- naire (supplemented with NTSS-9 scale) and visual analogue scale (VAS). After initial examination, a pharmacological evaluation of treatment was performed. RESULTS: Based on our data, prevalence of diabetic neuropathy was estimated at 54%, with painful form reaching 6.4%. Median age was 57.2-12.1, duration of diabetes mellitus - 16.5-10.6 years. Type 1 / type 2 ratio equaled 32.4% : 67.6%, male/female - 29.7%: 70.3%. Median HbA1c level was 8.4?1.6%. Ratio of chronic/acute forms of neuropathy was 267 : 20. Pain severity (as measured by VAS) distribution was as following: 15.6% ? severe, 40.6% ? moderate, 12.3% - mild, and 31.3% ? no pain symptoms. We did not find PDN to be associated with any parameters but sensory deficit (NTSS-9 and NDS: r=0.4; p 0.001). 21% of patients with chronic painful neuropathy (CPN) demonstrated allodynia and hyperalgesia besides typical symptoms. 97.9% of patients were previously treated with "pathogenetic" agents, 2.1% received anticonvulsants; overall efficiency was estimated at 22%. Patients with CPN and allodynia did not respond to treatment with alpha-lipoic acid (ALA), but pregabalin was efficient. After the examination treatment composition was adjusted as follows: treatment was ceased in 23% of patients, 11.9% received ALA, 53.6% - anticonvulsants, and 11.5% - antidepressants; overall efficiency was estimated at 75%. CONCLUSION: Prevalence of PDN is relatively low. 15.6% of patients suffer from severe pain. Neuropathic pain intensity correlates only with sensory deficit and is not dependent on any other parameters. CPN consists of two forms with higher and lower intensity of pain symptoms. Symptomatic therapy is indicated in acute variant of PDN, but also in chronic cases accompanied with allodynia and hyperalgesia. ALA appears to be effective as an initial stage of management of moderate or mild CPN.

Previously we elaborated software for analysis of diabetic foot outpatient clinic (DFOC) performance parameters. In this study we tested this software in 4 DFOCs in several cities. As a result, we obtained main parameters of treatment efficacy which can be base for elaboration of benchmarks for quality management in this field. This software can be helpful for administrators of the healthcare system in planning of measures for treatment results improvement and in assessment of these efforts efficacy.
