    Notes: Abstract Eleven patients with chronic progressive sensory ataxic neuropathy were examined clinicopathologically. Three cases were associated with primary Sjögren's syndrome (SS-SAN) and the others were considered to be idiopathic (ISAN). The major clinical symptom in both was loss of proprioceptive and kinesthetic sensation with some impairment of superficial sensation, with multifocal and asymmetrical distribution and progression. The truncal and trigeminal nerves were frequently involved. The motor system was substantially preserved. These somatic sensory and motor symptoms did not differ between ISAN and SS-SAN, but autonomic nervous system signs were more frequent in SS-SAN. Polyclonal elevations of serum IgG and/or IgA were seen in 8 patients. One autopsied case with ISAN combined with previous reports suggested that systemic T-and B-cell infiltration into the nervous tissues, as well as a wide variety of the visceral organs, may be a common finding in ISAN and SS-SAN, and could participate in the cause of this neuropathy and polyclonal hypergammaglobulinaemia.

    Notes: Abstract A quantitative analysis was made of the myelinated fibers in the lateral corticospinal tract (LCST) at the levels of the 6th cervical, 7th thoracic and 4th lumbar spinal segments in 20 patients between 19 and 90 years old, and who died of non-neurological diseases. The diameter frequency histograms of myelinated fibers of LCST showed a bimodal pattern with a sharp peak of the small myelinated fibers and broad slope of the large myelinated fibers. The ratio of small fiber to large fiber densities was significantly higher in the 6th cervical (P〈0.05) and 4th lumbar segments (P〈0.01) than in the 7th thoracic segments. The density of small myelinated fibers was significantly lowered with advancing age (P〈0.05∼0.001), while that of large myelinated fibers was not significantly decreased in the aged patients, although it showed a slight age-dependent declining tendency. Age-dependent decline of small fiber density was more prominent in the cervical and lumbar segments. Retraction of the axon-collaterals from large-diameter myelinated fibers, which are abundant in the cervical and lumbar segments, may contribute to the age-related diminution of the small myelinated fibers in the LCST.

    Notes: Abstract Spinal cord sarcoidosis is a rare disorder whose natural history and therapeutic outcome are not fully known. We examined four patients with spinal cord sarcoidosis both clinically and radiologically, particularly in relation to corticosteroid treatment. The initial manifestation was cervical myelopathy in three and uveitis in one. All four patients progressed slowly until corticosteroid therapy was initiated. The cervial spine was involved in all patients. Magnetic resonance imaging (MRI) showed spinal cord swelling with T2-weighted high intensity and linear leptomeningeal and patchy or diffuse intramedullary enhancement with gadolinium diethylene triaminepentaacetic acid. With corticosteroid therapy, dramatic improvement was seen on MRI, including disappearance or marked reduction of swelling and enhancement. Plasma levels of angiotensin-converting enzyme (ACE) were also markedly improved. In contrast, the clinical symptoms were little improved in one patient, unchanged in two, and rather worsened in one patient. Recurrence was seen on MRI at the maintenance dose in all four patients, without any dramatic change in clinical manifestation. MRI findings and plasma ACE are well correlated with active leasion of the spinal cord sarcoidosis, providing a useful marker for recurrence, but do not parallel the clinical manifestations.
