Recent investigations described a personal best marathon time as a predictor variable for an Ironman race time in recreational male Ironman triathletes. Similarities and differences in anthropometry and training were investigated between 83 recreational male Ironman triathletes and 81 recreational male marathoners. Ironman triathletes were significantly taller and had a higher body mass and a higher skin-fold thickness of the calf compared to the marathoners. Weekly training volume in hours was higher in Ironman triathletes. In the Ironman triathletes, percent body fat was related to overall race time and both the split time in cycling and running. The weekly swim kilometres were related to the split time in swimming, and the speed in cycling was related to the bike split time. For the marathoners, the calf skin-fold thickness and running speed during training were related to marathon race time. Although personal best marathon time was a predictor of Ironman race time in male triathletes, anthropometric and training characteristics of male marathoners were different from those of male Ironman triathletes, probably due to training of different muscle groups and metabolic endurance beyond marathon running, as the triathletes are also training for high-level performance in swimming and cycling. Future studies should compare Olympic distance triathletes and road cyclists with Ironman triathletes.
Objectives: The management of pilon fractures is a challenge and the outcome depends on multiple factors, one of which is the quality of reduction. In the literature, there is no assessment of anatomical reduction in pilon fractures. We also lack standard radiological parameters in large patient groups to measure the reduction. The main aim of this analysis was to define normal standard radiological values and identify potential specific types of ankle joint morphology (morphotypes) that might deserve special attention intraoperatively. Methods: We analyzed data of 103 healthy contralateral ankles collected within an observational and prospective multicenter study about tibial pilon fractures. We divided the patients according to their height into two groups, measured 11 radiological parameters, and compared them with each other and the literature. In addition, using cluster analysis, we could identify three morphotypes. Results: There is a statistically significant difference between the two groups in the lengths of three parameters: Mortise width, medial clear space, and length of the lateral malleolus, but not in the angles. The three morphotypes differ only in body mass index and the length of the lateral malleolus. Conclusion: Reference values from the literature are insufficient to assess a reduction after open reduction and internal fixation of tibial pilon fractures because they depend on the height. This does not apply to angles because they are independent of height. For clinical practice, a radiological control of the contralateral healthy ankle gives the best information about the reduction quality and should always be done, especially in normal weight males.
Background: While pyogenic spondylodiscitis due to Gram-positive aerobic bacteria and its treatment is well known, spondylodiscitis caused by anaerobic Gram-negative pathogen is rare. In particular, the spondylodiscitis caused by Veillonella species is an absolute rarity. Thus no established management recommendations exist. Case Description: A case report of a 79-year-old man with spondylodiscitis caused by Veillonella parvula with intramuscular abscess collection managed conservatively with stand-alone antibiotic therapy without a spinal stabilization procedure. A review of literature of all reported spondylodiscitis caused by Veillonella species was performed. After 3 week-intravenous therapy with the ceftriaxone in combination with the metronidazole followed by 3 weeks per oral therapy with amoxicillin/clavulanate, the complete recovery of the patient with the V. parvula infection was achieved. Conclusion: Treatment of the spondylodiscitis caused by Veillonella species should contain a beta-lactam with beta-lactamase inhibitor or third-generation cephalosporine. Six weeks of treatment seem to be sufficient for the complete recovery of the patient.
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.
