Pilates therapy improves core muscle function and axial stability but its effects on balance in idiopathic Parkinson’s disease (IPD) have not been evaluated. The objective of this study was to evaluate the effects of a Pilates exercise program on postural stability and balance confidence in people with IPD. Ten IPD patients (Hoehn & Yahr Stage 1-3) with a history of falls or nearfalls had the following assessments before and after completion of a 6-week supervised Pilates exercise program: Activities-Specific Balance Confidence Scale (ABC);Berg Balance Scale (BBS);Schwab and England Scale (SES);Unified Parkinson’s Disease Rating Scale (UPDRS);pull-test;timed-up-and-go (TUG);5-metre walk;static and dynamic posturography. There were significant improvements in BBS score, 5-metre walk time and TUG after the training program, as well as improvement trends in some posturographic measures. Participants also reported improved balance confidence with Activities of Daily Living (ADLs). Our findings suggest that Pilates therapy can be beneficial in IPD and warrants further evaluation in a larger study.

Stepping up to meet the challenge of freezing of gait in Parkinson’s disease

There has been a growing appreciation for freezing of gait as a disabling symptom that causes a significant burden in Parkinson’s disease. Previous research has highlighted some of the key components that underlie the phenomenon, but these reductionist approaches have yet to lead to a paradigm shift resulting in the development of novel treatment strategies. Addressing this issue will require greater integration of multi-modal data with complex computational modeling, but there are a number of critical aspects that need to be considered before embarking on such an approach. This paper highlights where the field needs to address current gaps and shortcomings including the standardization of definitions and measurement, phenomenology and pathophysiology, as well as considering what available data exist and how future studies should be constructed to achieve the greatest potential to better understand and treat this devastating symptom.

Diagnosis of spontaneous bacterial peritonitis: An update on leucocyte esterase reagent strips

引用

World Journal of Gastroenterology 2011年第9期17卷 1091-1094页

作者： Anastasios Koulaouzidis centre for Liver and Digestive disorders Royal Infirmary of Edinburgh 51 Little France Crescent Edinburgh EH164SA United Kingdom

Ascites remain the commonest complication of decompensated cirrhosis. Spontaneous bacterial peritonitis (SBP) is defined as the infection of ascitic fluid (AF) in the absence of a contiguous source of infection and/or an intraabdominal inflammatory focus. An AF polymorphonuclear (PMN) leucocyte count ≥ 250/mm 3 -irrespective of the AF culture resultis universally accepted nowadays as the best surrogate marker for diagnosing SBP. Frequently the results of the manual or automated PMN count do not reach the hands of the responsible medical personnel in a timely manner. However, this is a crucial step in SBP management. Since 2000, 26 studies (most of them published as full papers) have checked the validity of using leukocyte esterase reagent strips (LERS) in SBP diagnosis. LERS appear to have low sensitivity for SBP, some LERS types more than others. On the other hand, though, LERS have consistently given a high negative predictive value (> 95% in the majority of the studies) and this supports the use of LERS as a preliminary screening tool for SBP diagnosis. Finally, an AF-tailored dipstick has been developed. Within the proper setting, it is set to become the mainstream process for handling AF samples.
