1. [Early diagnosis of bacterial brain abscesses: interest of diffusion-weighted MRI]

Author

Abstract

Three cases of bacterial brain abscesses, in immunocompetent patients, are reported. In all these cases, the diffusion-weighted magnetic resonance (MRI) with apparent diffusion coefficient (ADC) map has permitted an early diagnosis and a rapid treatment. This emergency MRI showed in the three cases a low signal on TI-weighted images, a high signal on T2-weighted and echo-planar images, and a decrease of ADC (0.36- 0.49 x 10(-3) mm2/s). So, this new MRI technique provides an available and rapid element in the brain abscess diagnosis which often remains a complex clinical and radiological diagnosis.

Abstract

Botulinum toxin produces a transient presynaptic focal block at the neuromuscular junction. Thus it induces muscle weakness which has a significant beneficial effect on hemifacial spasm. Fifty-four patients were treated and received at least 2 and at the most 22 consecutive injections over a 5-year period. Injections were repeated every 9 weeks on average. The interval between injections corresponded to the time elapsed between the last injection and the re-emergence of spasms. Nineteen patients abandoned the treatment for various reasons. The most frequent side-effect was a ptosis which was observed in 1 out of 6 injections. Ptosis is due to diffusion of the botulinum toxin over a territory larger than expected. The results obtained in 42 patients were analyzed: there was no effect in 7 patients (17%); 11 patients improved by less than 50%; 13 by 50 to 70% and 11 more than 75%.

Abstract

Introduction: The aims of this study were to validate the French version of the SCales for Outcomes in Parkinson's Disease-PsychoSocial (SCOPA-PS) in individuals with Parkinson's disease (PD) who underwent deep brain stimulation of the subthalamic nucleus (DBS-STN), to confirm the unifactorial structure of this questionnaire, and to establish its psychometric properties., Methods: Routinely used psychological questionnaires (BDI-II, STAI-Y, PDQ-39, UPDRS III) and the SCOPA-PS were used for a cross-sectional observational study of 154 PD patients. SCOPA-PS acceptability, scaling assumption, reliability, ordinal confirmatory factor analysis and validity were assessed., Results: The ICC for two-week test-retest reliability was 0.88. SEM was 8.42. In confirmatory factor analysis, the one-factor model showed an acceptable fit to the data (Chi(2)/df=2.130; CFI=0.976; RMSEA=0.086). No floor or ceiling effects were observed. Skewness was 0.33. Item-total correlation coefficients ranged from 0.47 to 0.71. Cronbach's alpha was 0.86. SCOPA-PS SI correlated with PDQ-39 SI (rs=0.83) and with state-anxiety and depression (rs=0.56 and 0.69 respectively). The SCOPA-PS SI was higher in more depressed patients and in those with the most severe PD motor symptoms., Conclusion and Discussion: SCOPA-PS French version is a one-factor scale with satisfactory psychometric properties consistent with other language versions. This short scale can be used to evaluate the psychosocial component of QoL in PD patients treated with DBS-STN., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)
