Ageing process is associated with changes to the aspect, biomechanics, structure and function of the foot, it may be related with a marked presence of foot conditions, pain, disability and other overall health problems that constitute a major public health concern.Also, the prevalence of epidemiologic research found an incidence of foot problems which is even higher as a consequence of increasing life expectation. Several studies have also suggested that such foot disorders currently affect between 71 and 87% of older patients and are a frequent cause of medical and foot care.Thus, these kind problems are extremely common conditions in the general population, especially in the elderly who are associated with poor quality of life, balance impairment, increase the risk of falls, dificulty on putting shoes, fractures, restrict mobility and performance of activities of daily living that turn can produce serious physical, mental and social consequences in the older people.The role of the physician in the assessment, evaluation, and examination of foot problems is very important, yet it is often an overlooked and undervalued component of geriatric health care.The purpose of this article is to review and to provide an overview of the most common foot deformities precipitating factors, clinical presentation, evidence-based diagnostic evaluation, and treatment recommendations with a view to preventing medical conditions or deformities affecting the feet that may alter foot condition and general health amongst the elderly. 相似文献

The purpose of the present study was to quantify the learning curve for arthroscopic os trigonum excision using the log-linear model. Twenty-three consecutive feet underwent arthroscopic os trigonum excision and release of the flexor hallucis longus. The required time from the beginning of shaving of the soft tissue until completion of os trigonum excision and release of the flexor hallucis longus (van Dijk time) was recorded. Regression analysis was applied to predict the required time on the basis of the cumulative case volume after logarithmic transformation of both statistics. The mean required time was 35.2 (range 9 to 90) minutes. After logarithmic transformation, a significant linear correlation was observed between the required time and the cumulative case volume (p?=?.0043). The best-fit linear equation was calculated as log (y, estimated required time)? = ?0.41 log (x, case volume) + 1.86, resulting in an estimated learning rate of 75.3% (= 2?0.41). The results showed an overall time reduction in arthroscopic os trigonum excision in support of a learning curve effect with an ~75% learning rate, indicating that the required time for arthroscopic os trigonum excision can decrease by ≤25% when the cumulative volume of cases has doubled. 相似文献

Background
McArdle disease (glycogen storage disease type V) is an inborn error of skeletal muscle metabolism, which affects glycogen phosphorylase (myophosphorylase) activity leading to an inability to break down glycogen. Patients with McArdle disease are exercise intolerant, as muscle glycogen-derived glucose is unavailable during exercise. Metabolic adaptation to blocked muscle glycogenolysis occurs at rest in the McArdle mouse model, but only in highly glycolytic muscle. However, it is unknown what compensatory metabolic adaptations occur during exercise in McArdle disease.Methods
In this study, 8-week old McArdle and wild-type mice were exercised on a treadmill until exhausted. Dissected muscles were compared with non-exercised, age-matched McArdle and wild-type mice for histology and activation and expression of proteins involved in glucose uptake and glycogenolysis.Results
Investigation of expression and activation of proteins involved in glycolytic flux revealed that in glycolytic, but not oxidative muscle from exercised McArdle mice, the glycolytic flux had changed compared to that in wild-type mice. Specifically, exercise triggered in glycolytic muscle a differentiated activation of insulin receptor, 5′ adenosine monophosphate-activated protein kinase, Akt and hexokinase II expression, while inhibiting glycogen synthase, suggesting that the need and adapted ability to take up blood glucose and use it for metabolism or glycogen storage is different among the investigated muscles.Conclusion
The main finding of the study is that McArdle mouse muscles appear to adapt to the energy crisis by increasing expression and activation of proteins involved in blood glucose metabolism in response to exercise in the same directional way across the investigated muscles. 相似文献56.

拇短屈肌重建拇对掌功能在断腕再植术后的应用 总被引:1,自引:0,他引:1
目的 探讨断腕再植术后的拇对掌功能重建的临床效果。方法 腕关节活动受限是断腕再植术后常见的并发症,也使晚期对掌功能重建受到制约。临床上,对8例断腕再植术后成活尺神经深支功能恢复较佳者,采用拇短屈肌移位重建拇对掌功能,弥补了不足。结果 术后随访1—6个月,疗效满意,达到最佳功能,能从事原有工作。结论 断腕再植后,对拇对掌功能丧失或恢复不足者,采用拇短屈肌移位重建拇对掌功能是一种较为理想的方法。 相似文献
