Increased intrathecal inflammatory activity in frontotemporal dementia: pathophysiological implications.
Immunological mechanisms may be part of the pathophysiological mechanisms in frontotemporal dementia (FTD), but hitherto only vague evidence of such mechanisms has been presented. The aim of this study was to compare the cerebrospinal fluid (CSF) levels of the pro-inflammatory cytokines interleukin (IL)-1beta and tumour necrosis factor (TNF)-alpha, and the anti-inflammatory cytokine transforming growth factor (TGF)-beta in patients with FTD and normal controls. Furthermore, serum levels of TNF-alpha, TGF-beta, and IL-1beta were measured in FTD patients. ⋯ The results suggest an increased intrathecal production of both pro- and anti-inflammatory cytokines in FTD. As no correlations were found with the albumin ratio, and no correlations between CSF and serum levels of the cytokines were found, these changes in the CSF cannot be explained by a systemic overproduction of cytokines.

Case ReportsTwo families with autosomal dominant progressive external ophthalmoplegia.
We report here the clinical and genetic features of two new families with autosomal dominant progressive external ophthalmoplegia (adPEO). ⋯ Our cases illustrate the clinical variability of adPEO, add a novel pathogenic mutation in Twinkle (F485L) to the growing list of genetic abnormalities in adPEO, and reinforce the relevance of other yet unidentified genes in mtDNA maintenance and pathogenesis of adPEO.

Effects of surgery on the sensory deficits of syringomyelia and predictors of outcome: a long term prospective study.
To quantify the effects of surgery on the thermal deficits of syringomyelia and assess the predictors for such effects. ⋯ The duration of sensory deficits is the best predictive factor of the efficacy of surgery for the thermal symptoms of syringomyelia. Early surgery is required if these deficits are to be minimised.
