Systematic review of methods to diagnose infection in foot ulcers in diabetes.

AIM: To undertake a systematic review of the diagnostic performance of clinical examination, sample acquisition and sample analysis in infected foot ulcers in diabetes. METHODS: Nineteen electronic databases plus other sources were searched. To be included, studies had to fulfil the following criteria: (i) compare a method of clinical assessment, sample collection or sample analysis with a reference standard; (ii) recruit diabetic individuals with foot ulcers; (ii) present 2 x 2 diagnostic data. Studies were critically appraised using a 12-item checklist. RESULTS: Three eligible studies were identified, one each on clinical examination, sample collection and sample analysis. For all three, study groups were heterogeneous with respect to wound type and a small proportion of participants had foot ulcers due to diabetes. No studies identified an optimum reference standard. Other methodological problems included non-blind interpretation of tests and the time lag between index and reference tests. Individual signs or symptoms of infection did not prove to be useful tests when assessed against punch biopsy as the reference standard. The wound swab did not perform well when assessed against tissue biopsy. Semiquantitative analysis of wound swab might be a useful alternative to quantitative analysis. The limitations of these findings and their impact on recommendations from relevant clinical guidelines are discussed. CONCLUSION: Given the importance of this topic, it is surprising that only three eligible studies were identified. It was not possible to describe the optimal methods of diagnosing infection in diabetic patients with foot ulceration from the evidence identified in this systematic review.

冠心病心绞痛中医证候规律研究的比较分析

对冠心病心绞痛中医证候规律研究类的文献，从证候要素分布的差异、主要证候分类的差异、证候要素与理化指标的相关研究等方面进行比较分析，初步认为本病的证候要素应证组合是以气虚、血瘀为中心，阴虚、痰浊为次中心，气滞、阳虚、热蕴为外围所组成的多层次的证候体系。

智力残疾的适应性行为评估

适应性行为评估是智力残疾诊断与干预的必要依据。适应性行为的概念至今仍未有统一的观点，AAMR（2002）认为，适应性行为指的是概念、社会和应用3方面的技能，它的限制会影响个体的日常生活运作，进而影响其生活适应。对适应性行为进行评估的方法主要有测验法、行为观察法、功能性评估、生活质量评估和社会技能测量。无论使用什么方法进行评估，都应当以改善智力残疾个体现有状况为目的，考虑到各种评估方法的局限性，对智力残疾个体宜进行全面评估。     

Kluver-Bucy综合征

Kluver-Bucy综合征是一种较罕见的神经精神障碍引起的综合征，其特征为视觉失认、口部探索、饮食习惯改变、对视觉刺激过度注意、平静淡漠、性欲增强等，此外还有一些表现如失语、遗忘、痴呆和癫痫可能是人类所特有的。Kluver-Bucy综合征常由双侧颞叶病变引起。     

'This isn't very typical I'm afraid': observing community care complaints procedures

The new complaints procedures which local authority social services departments have been required to introduce represent an important mechanism for managing the change of culture associated with recent community care reforms. They also represent a new genre in mechanisms of redress for welfare recipients. This paper reports the findings of a study which has observed considerable diversity in the ways in which local authorities are interpreting the nature and purposes of the new procedures and, in particular, the functions of review panels established under those procedures. Variations in the composition of panels, in the style of review panel proceedings, in perceptions of the panels' powers, and in the ways that complaints and complainants are constituted are all discussed. Attention is drawn to four competing interpretations of the review panels' role and to the need for these to be clarified and prioritised.
