Congenital basilar impression: correlated neurological syndromes.

A series of 8 cases operated on for symptomatic basilar impression associated with occipitalization of the atlas is reported (with or without atlantoaxial dislocation). Symptoms of onset (such as the frequent association between nuchal pain and vertigo) are emphasized and analyzed in relation to the pathogenetic mechanism that underlies the multiform symptomatology of the basilar impression. The diagnostic workup for basilar impression foresees X-rays, magnetic resonance imaging and computed tomography. The most important diagnostic problem is that of considering the possible existence of such a pathology in the presence of very common symptoms such as nuchal pain and vertigo. The surgical treatment has certainly been useful both to improve and to stabilize the symptomatology mainly when there is atlantoaxial dislocation. In fact in these cases the symptomatology is more severe and progressive for the alteration of the transverse ligament of the atlas secondary to abnormal mechanical stimuli.

Interobserver reliability between neurologists in training of Parkinson's disease rating scales. A multicenter study.

A multicenter study has been conducted to determine the interobserver reproducibility of four of the most frequently used rating scales for Parkinson's disease: the Columbia University Rating Scale (CURS) and the Webster Rating Scale (WRS), both for assessing clinical signs; the Northwestern University Disability Scale (NUDS); and the Hoehn and Yahr staging. Four resident neurologists, inexperienced in the use of the four scales, independently examined 48 parkinsonian patients. The extent to which their assessments agreed was determined by calculating the Cohen k index after the scores had been recodified. The physicians' scores agreed substantially for the CURS and the Hoehn and Yahr scale, while those for the NUDS and the WRS agreed only moderately. Analysis of individual item scores within the scales suggests improvements that would offer greater interobserver consistency.

Cerebral complications of coronary by-pass surgery. A prospective study.

A prospective study was undertaken of cerebral complications in 91 patients undergoing coronary by-pass surgery. Patients showing clinically relevant neurological complications had longer pump-times but did not differ in pre-operative variables. Worsening of neurological state correlated with duration of pump-time but not with pre-operative variables. Duration of pump-time appears to be the main predictor of neurological complications after coronary by-pass surgery.
