Objectives. To investigate insulin-like growth factor I (IGF-1) levels in response to hyperbaric oxygen therapy (HBOT) for diabetic foot ulcers and to determine whether IGF-1 is a predictive indicator of wound healing in patients with diabetic foot ulcers. Design and Methods. We treated 48 consecutive patients with diabetic foot ulcers with HBOT. Alterations of IGF-1 levels in patients whose wound healed with HBOT were compared with those in patients who did not benefit from HBOT. Results. There was no significant difference in initial IGF-1 levels between the two groups (P = 0.399). The mean IGF-1 level increased with HBOT (P < 0.05). In the healed group, the mean IGF-1 increase and the final values were significantly higher (P < 0.05). In the nonhealed group, the mean IGF-1 increase was minus and the final values were not significantly different (P < 0.05). The increase in IGF-1 level with HBOT was significantly higher in the healed group (P < 0.001). Conclusions. IGF-1 increased significantly in the healed group. We believe that HBOT is effective in the treatment of diabetic foot ulcers, with an elevation of IGF-1. This alteration seems to be a predictive factor for wound healing in diabetic foot ulcers treated with HBOT.
The treatment of implant-related infections is troublesome. This study was conducted to compare the effectiveness of three different surgical modalities in the treatment of implant-related infection. A total of 32 Wistar albino rats were randomised into four groups after the establishment of implant-related infection: no treatment, surgical débridement, antibiotic-loaded bone cement and antibiotic-loaded autogenous bone. Microbiological colony counts were made at the sixth week in order to evaluate the effectiveness of of the treatments. The antibiotic-loaded bone cement group revealed superior results compared with the other groups in terms of reduction of microbiological colonies. Three animals in the bone cement group revealed extensive infection. Although antibiotic-loaded bone cement showed superiority over other treatment modalities, it should be employed after an unsuccessful trial of débride-ment because of the risk of extensive infection.
The Ilizarov fixator may be an alternative and effective means for neuropathic ankle arthrodesis, especially when the usage of internal fixation methods have some limitations.
Four-cortex fixation for diastasis after an ankle fracture should not be a routine procedure. We advocate three-cortex fixation because the clinical results are no different and there is less syndesmotic space obliteration postoperatively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
