Background: Inflammatory demyelinating diseases of the central nervous system represent a wide spectrum of entities and their classification cannot currently be regarded complete. Objective: Our aim is to describe a series of patients presenting with progressive myelopathy associated to a single demyelinating lesion of the spinal cord. Methods: We identified the patients affected by chronic progressive spinal cord dysfunction related to a single spinal cord lesion not satisfying the diagnostic criteria for any of the currently defined diseases. Results: Seven females and one male were included. The median age at onset of symptoms was 53 years (range 42–68) and the median follow-up was 8 years (range 5–12). Brain and spinal magnetic resonance imaging (MRI) scans detected only one single, circumscribed, T2 hyperintense, non-longitudinally extensive lesion at level of cervico-medullary junction or cervical cord, in the absence of Gadolinium enhancement or swelling. Cerebrospinal fluid (CSF) examination displayed neither oligoclonal bands nor raised IgG index. A response to immunosuppressive agents was observed in some of the patients. Serial control brain and spinal MRI did not reveal accumulation of new lesions. Conclusion: New entities or variants should be included among the inflammatory demyelinating diseases of the central nervous system, and their characterization may have relevant prognostic and treatment implications.

Objective: To evaluate whether balance deficit in patients with multiple sclerosis (MS), as assessed with eyes opened (EO) and closed (EC), is associated with damage of different structures of the central nervous system (CNS). Methods: Fifty patients with MS and 20 healthy controls (HCs) underwent static posturography to calculate the body’s center of pressure displacement (COP path) with EO and EC. They were scanned using a 3.0T magnet to obtain PD/T2 and 3D-T1-weighted images of the brain and spinal cord. We determined the mid-sagittal cerebellum area (MSCA) and upper cervical cord cross-sectional area (UCCA). We also measured the patients’ lesion volumes (T2-LVs) on the whole brain and at different infratentorial levels. Results: MS patients had wider COP paths with both EO and EC ( p < 0.001), and lower values in both MSCA ( p = 0.01) and UCCA ( p = 0.008) than HCs. The COP path with EO was associated with MSCA (Beta = − 0.58; p = 0.004) and T2-LV on middle cerebellar peduncles (Beta = 0.59; p = 0.002). The COP path with EC was associated with UCCA (Beta= − 22.74; p = 0.003) and brainstem T2-LV (Beta = 0.52; p = 0.01). Conclusions: Balance deficit in MS was related to atrophy of both the cerebellum and spinal cord, but the extent of COP path under the two different conditions (EO or EC) implied different patterns of damage in the CNS.

The widespread occurrence of the demyelinating diseases of the central nervous system makes the study of the events that accompany normal myelin formation one of major significance in neuropathology. In the latter part of the last century the earlier stages in the development of the nervous system in embryos were studied in detail by many investigators, but since then, in spite of its evident importance, this aspect of embryogenesis has attracted little attention from embryologists and neurohistologists. In view of the advances now being made in the chemistry of the nervous system, the time seems opportune to return to the problem of myelinogenesis with the hope of bringing together some of the many important relevant observations in neural morphology and biochemistry. In contrast to most earlier studies, the present one is restricted to some of the more outstanding features in the development of the neuroglia and myelin in the cervical spinal cord of the chicken embryo during the later stages of incubation.

Abstract Injuries that affect the central nervous system (CNS) can be catastrophic because they involve the brain or spinal cord, and determining the underlying clinical cause of impairment is essential in using the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), in part because the AMA Guides addresses neurological impairment in several chapters. Unlike the musculoskeletal chapters, Chapter 13, The Central and Peripheral Nervous System, does not use grades, grade modifiers, and a net adjustment formula; rather the chapter uses an approach that is similar to that in prior editions of the AMA Guides. The following steps can be used to perform a CNS rating: 1) evaluate all four major categories of cerebral impairment, and choose the one that is most severe; 2) rate the single most severe cerebral impairment of the four major categories; 3) rate all other impairments that are due to neurogenic problems; and 4) combine the rating of the single most severe category of cerebral impairment with the ratings of all other impairments. Because some neurological dysfunctions are rated elsewhere in the AMA Guides, Sixth Edition, the evaluator may consult Table 13-1 to verify the appropriate chapter to use.

ABSTRACT Radiologically thyroidectomized female Swiss mice were injected intraperitoneally with 131I-labeled thyroxine (T4*), and were studied at time intervals of 30 minutes and 4, 28, 48 and 72 hours after injection, 10 mice for each time interval. The organs of the central nervous system and the pituitary glands were chromatographed, and likewise serum from the same animal. The chromatographic studies revealed a compound with the same mobility as 131I-labeled triiodothyronine in the organs of the CNS and in the pituitary gland, but this compound was not present in the serum. In most of the chromatographic studies, the peaks for I, T4 and T3 coincided with those for the standards. In several instances, however, such an exact coincidence was lacking. A tentative explanation for the presence of T3* in the pituitary gland following the injection of T4* is a deiodinating system in the pituitary gland or else the capacity of the pituitary gland to concentrate T3* formed in other organs. The presence of T3* is apparently a characteristic of most of the CNS (brain, midbrain, medulla and spinal cord); but in the case of the optic nerve, the compound is not present under the conditions of this study.

ABSTRACTNeural prostheses which are commercially available include cochlear implants for treating certain forms of deafness and urinary bladder evacuation prostheses for individuals with spinal cord disorders. In the future we can anticipate improvements in bioelectrodes and biomaterials which should permit more sophisticated devices such as visual prostheses for the blind and auditory prostheses for the deaf based on microstimulation of the central nervous system.

Acute disseminated encephalomyelitis (ADEM) is a rare immune-mediated inflammatory and demyelinating disorder of the central nervous system. Its characteristic perivenular demyelination and inflammation aid in the differential diagnosis with other inflammatory demyelinating diseases. Here, we present a clinical case of ADEM, summarize its histological hallmarks, and discuss pitfalls concerning the most important neuropathological differential diagnoses.

At a quarterly meeting of this Association held last year at Nottingham, we showed the results of our experiments with toxins upon the spinal cord and brain of rabbits. Our main conclusion was, that the central nervous system could be infected by toxins passing up along the lymph channels of the perineural sheath. The method we employed in our experiments consisted in placing a celloidin capsule filled with a broth culture of an organism under the sciatic nerve or under the skin of the cheek; and we invariably found a resulting degeneration in the spinal cord or brain, according to the situation of the capsule. These lesions we found to be identical in morphological type and anatomical distribution with those found in the cord of early tabes dorsalis and in the brain and cord of general paralysis of the insane. The conclusion suggested by our work was that these two diseases, if toxic, were most probably infections of lymphogenous origin.

1. The Golgi material of the pyramidal cells of the cerebral cortex, the Purkinje cells of the cerebellum, and the multipolar cells of the medulla oblongata and ventral horns of the spinal cord of the sheep is present as filaments and as irregularly shaped bodies. In some of the cells, particularly in the lamb (Sheep V), the Golgi material has the appearance of a network. As it is frequently present as separate bodies it is suggested that it may always consist of discrete Golgi elements which are sometimes situated in close proximity or in contact with one another. Filamentous Golgi elements are present in the basal part of the cell processes. 2. An examination of neurones from the corresponding regions of the central nervous system of sheep infected experimentally with louping-ill showed that the Golgi material undergoes changes consequent upon the invasion of the cells by the virus. The Golgi material undergoes hypertrophy, and at the same time there is a reduction in the number of filamentous Golgi elements and a reduction in the amount of Golgi substance present in the cell processes. These changes are followed by fragmentation. All the neurones of a particular region are not affected equally at the same time. The Golgi material of the Purkinje cells tends to form groups in the cytoplasm prior to fragmentation. In the multipolar cells of the medulla oblongata the hypertrophy of the Golgi material is not as great as in the other regions of the central nervous system. The Golgi material of the motor nerve-cells of the ventral horns of the spinal cord undergoes considerable hypertrophy which is followed by a grouping of the Golgi elements and fragmentation.

ABSTRACT: This study describes suppurative infectious diseases of the central nervous system (CNS) in domestic ruminants of southern Brazil. Reports from 3.274 cattle, 596 sheep and 391 goats were reviewed, of which 219 cattle, 21 sheep and 7 goats were diagnosed with central nervous system inflammatory diseases. Suppurative infectious diseases of the CNS corresponded to 54 cases (28 cattle, 19 sheep and 7 goats). The conditions observed consisted of listerial meningoencephalitis (8 sheep, 5 goats and 4 cattle), suppurative leptomeningitis and meningoencephalitis (14 cattle, 2 goats and 1 sheep), cerebral (6 cattle and 2 sheep), and spinal cord (7 sheep) abscesses, and basilar empyema (4 cattle and 1 sheep). Bacterial culture identified Listeria monocytogenes (9/54 cases), Escherichia coli (7/54 cases), Trueperella pyogenes (6/54 cases) and Proteus mirabilis (1/54 cases). All cases diagnosed as listeriosis through histopathology yielded positive immunostaining on immunohistochemistry, while 12/17 of the cases of suppurative leptomeningitis and meningoencephalitis presented positive immunostaining for Escherichia coli. Meningoencephalitis by L. monocytogenes was the main neurological disease in sheep and goats, followed by spinal cord abscesses in sheep. In cattle, leptomeningitis and suppurative meningoencephalitis was the most frequent neurological disease for the species, and E. coli was the main cause of these lesions. Basilar empyema, mainly diagnosed in cattle, is related to traumatic injuries, mainly in the nasal cavity, and the main etiologic agent was T. pyogenes.
