    Notes: Summary Previous study have reported a significant improvement of peripheral neuropathy following combined pancreas and kidney transplantation attributed to improvement of blood glucose control by some authors and to elimination of uraemia by others. To asses the specific role of uraemia and hyperglycaemia in neuropathy, 16 diabetic uraemic patients with combined pancreas and kidney transplantation were compared to 9 diabetic patients with a renal graft only. Neurophysiological studies of peripheral neuropathy included ulnar and deep peroneal nerve motor conduction velocity, median and sural nerve sensory conduction velocity were performed at baseline and 1 and 2 years after transplantation. One year after transplantation mean nerve conduction velocity significantly improved in both groups. However, changes were statistically significant in the kidney-pancreas group only. At the 2 year follow-up nerve conduction velocity had increased further in the pancreas-kidney group only. These data suggest that improvement of nerve conduction velocity following pancreas and kidney transplantation is predominantly due to the long-term euglycaemic state.

    Notes: Summary Diabetic polyneuropathy is a common, disabling chronic complication of diabetes mellitus. Previous studies have suggested that combined pancreas-kidney transplantation can ameliorate nerve conduction. The relative contribution of the correction of hyperglycaemia and uraemia on nerve function is still a matter of debate. Nerve conduction velocity (NCV) was assessed before and after simultaneous pancreas and kidney transplantation, and before and after pancreas graft failure in five insulin-dependent diabetic (IDDM) patients affected by severe diabetic polyneuropathy. Sensory and motor NCV were recorded in five nerves and expressed as a cumulative index for each patient. Metabolic control was evaluated by fasting blood glucose and glycosylated haemoglobin levels. NCV index was below normal values before transplant: –3.8 ± 0.7 (normal value: 0.89), improved 1 and 2 years after transplant: –3.1 ± 1.3 and –2.6 ± 0.9 (p = 0.0019), stabilised until pancreas failure and deteriorated to pre-transplant values 2 years after pancreas graft failure: –3.6 ± 1.0 (p = 0.034). Fasting blood glucose levels worsened after pancreas graft failure. HbA1 c levels, in the normal range during functioning pancreas graft (6.6 ± 0.6 %), deteriorated after its failure (8.0 ± 0.6 %, p = 0.04). Kidney function was preserved. These data support a positive effect of pancreas transplantation per se on NCV in IDDM subjects with diabetic polyneuropathy, thus demonstrating that metabolic control provided by a self-regulated source of insulin not only halts but also ameliorates nerve function, even if polyneuropathy is advanced.

    Notes: Abstract Brain and spinal cord magnetic resonance imaging (MRI), multimodal evoked potentials (EPs) and cerebrospinal fluid (CSF) analysis were performed in 27 patients with acute myelopathy of unknown aetiology (AMUA), to detect the diagnostic and prognostic values of paraclinical tests at presentation. Spinal cord MRI was abnormal in 56% and brain MRI in 33% of the patients. Visual EPs were abnormal in 7%, median somatosensory EPs in 17%, tibial somatosensory EPs in 56% and motor EPs in 35% of the cases examined. Brain-stem acoustic EPs were normal in all the patients. CSF oligoclonal bands (OBs) were detected in 30% of cases. The patients were divided into subgroups according to the short-term clinical outcome (complete, partial or absent recovery). There were no significant differences among the three groups as regards MRI findings. Patients with complete recovery showed a significantly lower frequency of tibial somatosensory EP and motor EP abnormalities. According to the paraclinical findings at onset and on the basis of a long-term clinical follow-up (mean duration 24 months), 6 patients were diagnosed as having clinically definite multiple sclerosis, while 21 did not develop further neurological disturbances. Only the presence of CSF OBs was significantly more frequent in patients with definite multiple sclerosis. Our study indicates that EPs exploring spinal cord function are more powerful than spinal MRI for predicting the short-term outcome of AMUA, while the combined use of brain MRI and CSF OBs has the highest negative predictive value for the subsequent development of clinically definite multiple sclerosis.

    Notes: Abstract We evaluated the risk of developing clinically definite multiple sclerosis (CDMS) after an acute attack of isolated optic neuritis (ON) in 112 patients, in relation to demographic and paraclinical findings. Patients were examined by brain MRI, CSF analysis, and multiple evoked potentials (EPs); 10 were lost to follow-up, and the other 102 were enrolled in a prospective study (follow-up duration 6.3 ± 2.2 years). Of these, 37 (36.3%) developed CDMS after a mean interval of 2.3 ± 1.6 years. The risk of developing CDMS was 13% after 2 years, 30% after 4, 37% after 6, and 42% after 8 and 10 years. Gender, age, and season of ON onset did not affect the risk. MS occurred in 37 of 71 patients (52.1%) with one MRI lesion or more; no patient with a normal MRI developed the disease. MS developed more frequently in patients with intrathecal IgG synthesis than in those without (43% vs. 28%), but the difference was not statistically significant. Multiple EPs showed a slight predictive value only including somatosensory EPs of the lower limb. Multiple sclerosis was mild in most cases (EDSS 2.2 ± 1.9). The EDSS was less than 4 in 32 cases (86%), between 4 and 6 in 2 (5%), higher than 6.5 in 3 (8%).

    Notes: Abstract Recent reports suggest the possible beneficial effects of haemopoietic stem cell transplantation (HSCT) in autoimmune diseases such as multiple sclerosis (MS). The definition of the risk/benefit ratio for such a treatment is perceived as a major issue for the neurological community worldwide. The First Consensus Conference on Bone Marrow Transplantation in Patients with Multiple Sclerosis was held in Milan, Italy on 21 February 1998. Participants from 16 European, North American, and South American countries discussed the guidelines form performing HSCT in MS. This conference was organized in order to : (a) define criteria for patient selection; (b) define transplantation procedures to maximize efficacy of the treatment and minimize its toxicity; (c) standardize patient outcome evaluation; and (d) establish an international working group to evaluate the efficacy and safety of HSCT in MS and to study the immunological changes related to HSCT in MS patients. During the meeting in Milan agreement was reached on: (a) the preparation and distribution of a consensus report on HSCT in MS and (b) the design of an open trial for an initial assessment of the safety and efficacy of HSCT in MS. The consensus reached during the meeting and the design of the clinical trial are summarized in this contribution.

    Fatigue and magnetic resonance imaging activity in multiple sclerosis (1999)

    Notes: Abstract Fatigue is a frequent and often severe symptom in multiple sclerosis. Pathogenic mechanisms proposed for fatigue include the release of proinflammatory cytokines, which is thought to have an important effect on changes in the blood-brain barrier (BBB). To investigate whether fatigue is related to BBB disruption we studied 11 relapsing-remitting MS patients participating in a multicenter longitudinal study comparing the sensitivity of monthly enhanced magnetic resonance imaging (MRI) after standard-dose and triple-dose injection of gadolinium-diethylene triaminopentoacetic acid (Gd-DTPA). Serial Gd-enhanced MRI studies were performed in two separate sessions every 4 weeks for 3 months. An expanded version of the Fatigue Severity Scale, including 29 items, was administered 24 h before each MRI examination. No relationship was found between the number and volume of Gd-enhancing lesions and fatigue scores at any monthly examination over the study period. Furthermore changes in MRI activity were not significantly related to changes in fatigue scores. These results were obtained on triple-dose delayed scanning, which is more sensitive than standard-dose scanning in detecting areas of BBB disruption. Our preliminary results thus do not support the hypothesis of a relationship between BBB alterations and fatigue severity in multiple sclerosis.

    Neurophysiological imaging techniques in dementia (1999)

    Notes: Abstract Neurophysiological methods, such as electroencephalography (EEG) and event-related potentials, are useful tools in the investigation of brain cognitive function in normal and pathological conditions, with an excellent time resolution when compared to that of other functional imaging techniques. Advanced techniques using a high number of EEG channels also enable a good spatial resolution to be achieved. This, together with the possibility of integration with other anatomical and functional images, may increase the ability to localize brain functions. Spectral analysis of the resting EEG, which gives information on the integrity of the cortical and subcortical networks involved in the generation of cortical rhythms, has the limitation of low sensitivity and specificity for the type of cognitive impairment. In almost all types of dementia, decreased power of the high frequencies is indeed observed in mild stages, accompanied by increased power of the slow rhythms in the more advanced phases. The sensitivity for the detection of spectral abnormalities is improved by studying centroid modifications. More specific information on the type of dementia can be provided by coherence analysis of the resting EEG, a measure of functional cortico-cortical connections, which has different abnormal patterns in Alzheimer's disease, cerebrovascular dementia and dementia associated with multiple sclerosis. Another tool for improving the assessment of demented patients is the study of EEG activity related to particular tasks, such as event-related potentials and event-related desynchronization/synchronization of the EEG, which allow the study of brain activation during cognitive and motor tasks.

    Notes: A rapid and reliable PCR-RFLP method was optimized to identify marine fish fillets. Seabass, seabream, umbrine, and dentex were considered in the study. After DNA extraction and PCR, the 359 bp amplification products, obtained from gene encoding the cytochrome b, were subjected to restriction enzyme analysis. All the enzymes tested were not able to distinguish all the 5 species at the same time, but the combination of the results obtained from the digestion HaeIII and NlaIII can be used to differentiate the fish fillets considered. The method described is sensitive, rapid, and reliable, and it could be used to expose fraudulent substitutions with less valuable fish.
