Peripheral nerve involvement in chronic liver disease. Clinical and electrophysiological study.

A clinical and electrophysiological study was carried out on 19 selected patients with chronic liver disease. Clinical signs of peripheral nerve involvement were found in 4 patients (21%); while electrophysiological impairment was present in 11 patients (57.8%). These abnormalities were mostly limited to the sensory and motor fibers of the tibialis posterior nerve. Our data confirm the presence of peripheral nerve involvement in chronic liver disease, and that it may be evidenced by careful electrophysiological examination.

F-wave study in patients with chronic renal failure on regular haemodialysis.

Motor nerve conduction along the entire length of ulnar and tibialis posterior nerves was studied in 30 uraemic patients and in 20 control subjects. The M and F latencies, MNCV (between the stimulus sites), FWCV (between the spinal cord and the stimulus sites) and F-ratio (conduction time ratio of proximal to distal segment) were assessed to evaluate the conduction in the proximal versus the distal nerve segment. In the uraemic patients, the slowing of nerve conduction involved both segments of the tested nerves to the same extent. In fact, the F-ratio did not show any significant difference between the two groups; in only one patient was its value lower than the normal limit in the tibialis posterior nerve.

[Hemorrheological survey in dystrophia myotonica and other muscular dystrophies].

We have determined the main hemorheological parameters in a group of patients suffering from myotonic dystrophy and in another group with oculopharyngeal or limb-girdle myopathy. From the results we have obtained it is evident that of all the rheological parameters considered only hematocrit, fibrinogen and fibrinogen/albumin ratio are different in patients with myotonic dystrophy when compared to that of normal controls. There were no variations in blood, plasma and serum viscosities and in erythrocyte filterability. In addition, hemorheological alterations were not present in patients with oculopharyngeal or limb-girdle myopathy.

[Velocity of nerve conduction in children and adolescents with type I diabetes mellitus: clinical, metabolic and immunologic correlations].

Clinical, metabolic, neurophysiologic and immunological data were obtained in a group of 50 patients with type I diabetes mellitus Results were compared with those obtained in 30 healthy subjects of comparable age. M.N.C. (median nerve conduction) velocities and sensitive latency were observed to be significant lower in the diabetic patients rather than in the controls. These abnormalities were correlated with the duration of diabetes rather than with the glucose control. The positivity for circulating immune complexes was found to be associated with a significant reduction of median sensory nerve conduction velocity. There results suggest that in addition to metabolic, genetic, vascular and hormonal abnormalities also immunologic factors may play a role in the pathogenesis of diabetic neuropathy.

[Description of a case of multiple sclerosis with psychotic disorders at the onset].

The authors report on the case of a woman, aged 29, who was suffering for 15 years from an unipolar manic psychosis and for 5 years from ataxia, speech troubles and urine incontinence. The diagnosis of MS was supported by the presence of a marked increase of liquoral IgG as well as Link's and Tourtelotte's index. CT scan, EEG and VEPs were normal. The relationships between the two clinical conditions are briefly discussed on the view of data of the literature.
