Abstract
We demonstrated that an IgM M-protein from a patient with motor neuron syndrome had antibody activity against gangliosides GM1, GD1b, and asialo GM1. Studies with a sugar-binding lectin suggested that the epitope in the patient's M-IgM involved the Gal(beta 1-3) GalNAc moiety. Immunohistological techniques demonstrated staining of axons in the lumbar roots, granular cells, and white matter in the cerebellum by the patient's M-IgM. We propose that, in this case, an autoimmune mechanism of motor neuron syndrome associated with a monoclonal protein is most likely.

Abstract
We investigated two patients with the idiopathic hypereosinophilic syndrome and peripheral neuropathy. Clinical, EMG, and pathological findings were consistent with axonal polyneuropathy. Morphologic changes of the nerve biopsies suggested axonal damage secondary to increased endoneurial pressure from leakage of capillaries. We postulate that endothelial cell damage, followed by nerve edema, is the first step in the pathogenesis of peripheral neuropathy in these patients.

Abstract
An adult with clinically and neuroradiologically occult diastematomyelia is described. The neuropathological study revealed an unusual duplication of the spinal cord not associated with osteocartilagineous anomalies. This anomaly probably occurs early in fetal life as an isolated lesion of the neural tube. The embryological mechanism is discussed.

Abstract
Neuropathological features of a case of ataxia-telangiectasia are reported. The main findings were the presence of Lewy bodies, cytoplasmic inclusions and axonal spheroids in the brainstem nuclei; pathological changes of spinal cord closely resembled those reported in the familial form of amyotrophic lateral sclerosis. In immunocytochemical studies, filamentous inclusions and axonal spheroids strongly reacted with monoclonal antibodies against neurofilament subunits. The results show that disorganization and accumulation of neurofilament proteins occur in ataxia-telangiectasia.

Abstract
This is a retrospective analysis of marrow function in 171 recipients of an HLA-matched bone marrow transplant (BMT). Only patients with detectable hemopoiesis as indicated by leukocyte counts greater than 1.0 x 10(9)/l and platelet counts greater than 25 x 10(9)/l who were alive on day 30 were entered in the study. Poor marrow function was detected in 24 (14%) patients as indicated by a decrease in the peripheral blood counts to less than 40% of the maximal preceding values post-transplant in association with reduced marrow cellularity. Leukopenia (n = 4), thrombocytopenia (n = 3) or a combination of the two (n = 17) occurred 62 +/- 23 (SEM) days post-transplant and was associated with acute graft-versus-host disease (AGVHD) grade II or more and infection (n = 19) in the absence of clear rejection or persistence/recurrence of malignant disease. A multivariate analysis showed that AGVHD was the major risk factor (p = 0.001) for developing poor graft function. In the 24 patients with poor graft function, hemopoietic recovery was strongly associated with resolution of AGVHD and of infections. Their survival (27%) was the same as survival for other patients matched for GVHD who had no pancytopenia. The causes of death were GVHD (n = 13), pneumonia (n = 3) and infections (n = 1). This study draws attention to a particular type of poor graft function following allogeneic BMT that is characterized by (1) normal timing and quality of engraftment, (2) AGVHD of grade II or greater, (3) progressive and severe pancytopenia, and (4) multiple infections with poor clinical condition.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Dorsal root ganglion cells, obtained from 8-10-week human foetuses, were isolated by enzymatic procedure and grown on poly-L-lysine-coated coverslips. Most of the cultured cells showed the ultrastructural and immunological features of normal peripheral neurons. By immunocytochemistry neurons reacted with IgM antibodies with specificity for myelin-associated glycoprotein (MAG) from patients affected with IgM k gammopathy and peripheral neuropathy. The antigen was located on the plasmalemma of both perikarion and axon. We suggest that anti-MAG antibodies do not recognize neuronal MAG, but rather an epitope shared with different glycoproteins.

Abstract
Clinical, neuropathological, and immunohistochemical (PAP) findings are reported in a 7 month-old girl with Tuberous sclerosis (TS). Polycystic kidneys and massive cardiomegaly constituted the prominent pathological features. The neuropathology of the syndrome was characterized by Megalencephaly, Subependymal giant cell astrocytoma, Very large protoplasmic astrocytes in Golgi-rapid method preparations of cortical tubers and Glial fibrillary acidic protein (GFAP)-negative giant cells in the subependymal nodules as well as in the cortical tubers. The identity of these giant cells is discussed.

Abstract
A case of congenital toxoplasmosis is reported in which the patient died at 32 days following seizures, coma and respiratory disturbances. Neuropathological examination showed numerous foci of softening throughout the brain. Histological examination disclosed widespread areas of inflammatory necrosis. Circumscribed areas of granulomatous inflammation were also found. Cysts containing a variable number of microorganisms and toxoplasmas free in the damaged areas were frequently observed. Small calcifications were scattered in the cerebral cortex and basal ganglia. Electron microscopy of postmortem brain specimens demonstrated toxoplasmas at various stages of development. The microorganism is enveloped by a two-layered membrane, the pellicle. Replication occurs in a vacuole inside the host cell. Following replication the newly formed parasites, the trophozoites, are released. Several replications without release may also occur with consequent cyst formation. The motile form of the toxoplasma, the tachyzoite, is fusiform with truncated cone shape of the anterior ending which is the presenting surface modified for host cell penetration. The modality of transplacental transmission and the clinical syndromes associated with toxoplasma infection are discussed. EM even of post mortem material contributes to knowledge of the structure of the parasite and of its life cycles.

Abstract
The clinicopathological findings are reported in a child with congenital oculofacial diplegia, paresis of pharyngeal and laryngeal muscles, and concomitant tetraparesis. The constellation of signs and symptoms correlates with a complex picture of maldevelopment, including absence of olfactory bulbs, hippocampal abnormalities, hypoplasia of the corpus callosum and of the cerebellum, and severe hypoplysia of the descending pathways. We stress the role played by the hypoplasia of the descending fibres, with consequent denervation of the cranial nerve nuclei, in producing the Möbius-like picture.

Abstract
4 patients with prosopagnosia are described. They presented associated neuropsychological deficits (achromatopsia, topographical disorientation) and visual field defects. In 1 case, gross pathological examination revealed bilateral symmetrical infero-medial occipito-temporal infarcts. In 2 other cases, computer tomography (CT) demonstrated bilateral inferior temporo-occipital infarction. In 1 case CT showed only occipital infarctions in the occipital lobes. This brings to 16 the number of anatomically studied cases of prosopagnosia (8 by necropsy, 8 by CT). In contrast to clinical localization, which often indicates only a right cerebral lesion, all anatomically verified cases of prosopagnosia exhibit bilateral lesions in the posterior cerebral artery distribution.

Abstract
Light-, electron microscopic and immunopathological findings in a nerve biopsy of a patient with peripheral neuropathy associated with monoclonal gammopathy are reported. Loss of fibers, Wallerian-like degeneration and segmental demyelination were the most important features observed in light microscopy. In E.M. widening of the peripheral lamellae of myelin sheaths and occasional aspects of hypermyelination were seen. Immunoperoxidase study showed binding of IgM (k light chain) on the myelin sheath. The possible pathogenetic implications of these findings are discussed.

Abstract
Repeated neurophysiological investigations over a six year period are reported in two children with histologically proven Alexander's leucodystrophy. The EEG alterations were already detectable at an early stage of the disease with subsequent progressive deterioration in both cases. There was no definite abnormality in the ERG-VEP studies which were only carried out in the younger patient. The EEG features in the course of the illness are different from those seen in most of the identified genetically determined neurometabolic diseases as well as in the group of so-called leucodystrophies of similar age groups. However, the EEG-ERG-VEP features are not sufficiently characteristic to be diagnostic.
