Conventional and quantitative EEG in the diagnosis of delirium among the elderly.
This study was performed to determine whether an admission quantitative EEG (QEEG) could assist in the differential diagnosis of encephalopathy among a group of elderly subjects with delirium, dementia, and delirium coexistent with dementia. Thirty four subjects from 57 to 93 years had standard 17-channel EEG and quantitative EEG studies, using a linked-ear reference. EEGs were independently rated by two electroencephalographers blind to clinical diagnosis, using conventional criteria to assess the degree of encephalopathy. ⋯ Variables which collectively distinguished normal from encephalopathic records were Mini-Mental State Examination scores and relative power in the alpha frequency band. Variables which collectively distinguished delirium from dementia were EEG theta activity, relative power in delta, and brain map rating. The results suggest that cross-sectional QEEG study is potentially useful in the early differential diagnosis of encephalopathy, and that the variables which distinguish normal from encephalopathic patients might differ from the variables which distinguish delirium from dementia.

ReviewTreatment of lower urinary tract dysfunction in patients with multiple sclerosis. Committee of the European Study Group of SUDIMS (Sexual and Urological Disorders in Multiple Sclerosis)
Bladder symptoms in patients with multiple sclerosis (MS) are common and usually arise as a result of spinal lesions which interrupt the neural pathways connecting the pontine micturition centre to the sacral spinal cord. Thus these symptoms are particularly likely to occur in those with lower limb neurological deficits. Fortunately bladder dysfunction in MS is rarely associated with serious upper tract disease so that the problem is usually one of symptomatic management. ⋯ Treatment is aimed at minimising both these effects. Oral anticholinergic medication can be effective in reducing detrusor hyperreflexia and intermittent catheterisation is used to reduce abnormally high post micturition residual volumes. With this simple treatment, often used in combination, many less severely affected patients with MS can gain considerable improvement in controlling urinary continence.

Two clinical forms of multiple sclerosis (MS), primarily chronic progressive MS (PCP MS) and relapsing/remitting MS (R/R MS) have been shown to differ in several respects. The results of genomic HLA class II typing with restriction fragment length polymorphism analysis of 62 MS patients from Western Norway, 42 with R/R MS and 20 PCP MS, are reported on here. ⋯ This finding supports the hypothesis that R/R and PCP MS are immunogenetically separate entities. In contrast with a previous investigation of Norwegian MS patients, no association of MS with glutamine at position 34 of the HLA-DQ alpha chain or with defined sequences of the HLA-DQB1 gene was found.
