影响糖尿病足坏疽愈合的因素及针对性护理研究

目的探讨针对影响糖尿病肢端坏疽患者愈合因素进行针对性的护理。方法在600例糖尿病足坏疽住院患者中随机抽取168例分成2组,根据2组患者血浆蛋白、动脉硬化下肢血流量、微循环障碍程度、患足骨质破坏情况、缺乏糖尿病足坏疽的防治知识进行分析,找出影响愈合的因素,并做好针对性的护理工作。结果168例糖尿病足坏疽患者,下肢血流量、足背动脉搏动及甲襞微循环比较,2组差异有显著性意义(P<0.05);2组足坏疽合并肾病、骨质破坏和血红蛋白改变情况比较,2组差异有显著性意义(P<0.05)。结论根据糖尿病足坏疽患者影响愈合的因素,进行针对性的护理,加快了糖尿病足坏疽患者的愈合速度,同时综合治疗有利于糖尿病足坏疽的早日愈合,可以减少截肢,提高了糖尿病足坏疽患者的生活质量。     

更昔洛韦治疗婴幼儿手足口病的疗效观察

目的 探讨更昔洛韦对婴幼儿手足口病（HFMD）的临床疗效。方法 将65例婴幼儿HFMD患儿随机分为治疗组和对照组，治疗组加用更昔洛韦，观察临床有效率及不良反应率，并对结果进行统计学分析。结果 临床有效率治疗组为90．91地，对照组56．25％，引起白细胞下降，血小板下降治疗组为33．33％、27．27％，对照组为9．38％、3．13％，差异均有显著性。结论 治疗组疗效优于对照组，但须随访对白细胞和血小板的影响。     

Biliopancreatic diversion with duodenal switch vs. gastric bypass for severe obesity

Conclusion In the year 2003 there is no “one best bariatric operation” for every severely obese patient. The choice of operation must be tailored to each individual patient’s needs and wishes. For the superobese patient, the patient diagnosed with intestinal metaplasia of the stomach, and for those patients who do not wish to undergo the severe dietary restrictions imposed by the RNY-GB, the BPD-DS is a valuable surgical option.     

Mortality in patients with diabetic neuropathic osteoarthropathy (Charcot foot).

OBJECTIVE: To determine the mortality of a population of patients diagnosed with Charcot neuropathic osteoarthropathy managed by a single specialist unit and to compare the results with a control population. METHODS: We have undertaken a retrospective analysis of all cases of Charcot foot on the comprehensive database which has been maintained at the specialist diabetic foot clinic at the City Hospital, Nottingham since 1982. Survival and the incidence of amputation (major and minor) was compared with a control population referred with uncomplicated neuropathic ulceration. Controls were individually matched for gender, age (+/-2 years), disease type, disease duration (+/-2 years) and year of referral (+/-3 years). RESULTS: Forty-seven cases (21 female, 26 male) of Charcot foot were identified, of whom 18 (38.3%) had Type 1 diabetes. Mean age and disease duration at presentation were 59.2 +/- 13.4 (sd) and 16.2 +/- 11.2 years, compared with 59.7 +/- 12.6 and 16.3 +/- 11.2 years, respectively, in the controls. Twenty-one (44.7%) of those with Charcot had died, after a mean interval of 3.7 +/- 2.8 years. This compared with 16 (34.0%) after a mean 3.1 +/- 2.7 years in the control group. Mean duration of follow-up in the survivors was 4.7 +/- 4.9 years (Charcot) and 5.3 +/- 3.9 years (controls). A total of 11 (23.4%) Charcot patients had had a major amputation on the side of the index lesion, compared with five (10.6%) controls. There was no difference between the two groups (P > 0.05, Chi-square). CONCLUSIONS: The mortality in this group of patients with Charcot foot was higher than expected. Nevertheless, there was no difference between those with Charcot and those with uncomplicated neuropathic ulceration. It is possible that it is neuropathy, rather than Charcot osteoarthropathy, which is independently associated with increased mortality in diabetes. The mechanism underlying any such association is not known. There is a need for a formal, prospective, multicentre study to investigate the life expectancy and cardiovascular risk of those with Charcot osteoarthropathy.

A review of the effects of external pressure on skin blood flow

The human foot is a complex mechanical structure consisting of bones, ligaments and joints. They act together to provide a robust system capable of absorbing and dissipating the intermitted pressure that is subjected to its plantar surface during walking to prevent soft tissue breakdown. Current studies suggest that plantar foot pressure may lead to soft tissue breakdown (e.g. neuropathic ulceration) and hence research has so far concentrated on investigating the mechanical effects of plantar foot pressure on the foot’s integrity. This has been possible through the widely available pressure and force platforms as well as in-shoe pressure systems. However, to understand how plantar foot pressure causes soft tissue breakdown it is vital to investigate both the physiological–mechanical interactions between the skin and plantar foot pressure. This review suggests that with the current advances in technology, the physiological response of skin blood flow to mechanical plantar foot pressure should be investigated and correlated further, both during static and dynamic loading, by developing a new system capable of either measuring both variables simultaneously or by synchronising two systems in real time.
