Abstract
The immediately postbirth extra uterine adaptation is the most important cause of death in the first two hours of life. In all risky cases, it is necessary to effect efficient and on time techniques of newborn resuscitation, because dubitation or delay may be very dangerous for the infant. In Italy courses of equipment in newborn resuscitation are regularly performed, but an excellent level of technique can be obtained only with continuous daily practice. Then, particularly in little hospitals where it is unusually necessary to act resuscitation on a newborn, courses of simulation for medical and nursering staff would be opportune to prevent neonatal handicap and to deal with the professional liability in the best way. The Italian current jurisprudence, in fact, has slowly confined the application of 2236 article of Civil code about professional liability in particularly difficult efforts. The Italian law asserts that a professional specialist is trained to be able resolve any type of problem among those of his specialistic competence, even if technically very difficult. It should be opportune to train health staff with practical exercises, in order to obtain complete technical skills in all neonatal centers.

Abstract
Simultaneous bilateral plantar sympathetic skin response (SSR) was studied in 25 patients with early stage idiopathic Parkinson's disease (IPD), characterized by monolateral motor involvement (Hoehn and Yahr, stage <2) and without clinical evidence of autonomic dysfunctions. Thirteen (mean age: 68.69 +/- 7.70, range 55-76) had extrapyramidal clinical signs only at the left body side, 12 (mean age 66.60 +/- 7.43, range 51-73) at the right body side. A group of 25 healthy, age-matched, subjects were also evaluated. To evoke the responses, trains of 10 electrical pulses were applied at different intensities and frequencies. Only intensities of stimulation > or = 5 times the sensory electrical threshold always assured bilateral plantar responses in all the examined subjects. Amplitude asymmetry between left and right responses was found only in the IPD patients (P < 0.05). The amplitude reduction corresponded to the motor affected side. No analogue latency variation was observed in any group. Independently from the peripheral or central origins of such phenomena, these findings suggest that simultaneous bilateral SSR amplitude evaluation could be useful, in early IPD patients, to demonstrate and to monitor the sympathetic cholinergic dysfunction, despite the lack of autonomic symptoms.

Abstract
We present a patient with benign IgM-gamma anti-Sulfatide (SUL) whose neuropathy was transferred in newborn rabbits. The patient's clinico-pathological picture of anti-SUL-associated demyelinating neuropathy is reported. The monoclonal IgM antibodies prepared by Tatum's method, that retained their biological activity, were passively transferred to newborn rabbits. The passive transfer produced demyelinating nerve lesions very similar to the donor antibody neuropathy. In experimental lesions we observed the human IgM anti-SUL antibodies binding to Schmidt-Lanterman incisures and nodes of Ranvier. We postulate that the myelin-specific and complement-dependent lesions observed in the peripheral nerve support the potential demyelinating role of anti-SUL antibodies. Moreover, the pattern of the antibody binding to the perineuronal sheath of satellite cells in dorsal root ganglia strengthen the hypothesis that anti-SUL antibodies may have a pathogenetic role in this sensorimotor syndrome.

Abstract
Sera from 3 patients with breast or ovarian tumors and paraneoplastic cerebellar degeneration (PCD) contained anti-Purkinje cell antibodies (PCAbs) which also bind to other neurons on frozen sections of adult rodent brain. PCAbs tested on new-born rodent (rabbit, rat, mouse) brain tissue detected only oligodendrocyte-like cells (ODLC) in the white matter and allowed us to speculate on the nature of the antigenic structure in the neuronal cytoplasm. All these PCAbs appear histochemically identical and recognize antigens which belong to so-called "Yo" proteins.

Abstract
We investigated the role of anti-myelin-associated glycoprotein (MAG) IgM and complement (C) in the pathogenesis of myelin alterations occurring in patients with anti-MAG-associated polyneuropathy. For this purpose, we separately studied the effects of anti-MAG antibodies and terminal C complex (TCC) after injection into the rabbit sciatic nerve. The two different local treatments produced identical ultrastructural abnormalities such as intramyelinic edema, myelin vesiculation and, in particular, separation of the major dense lines with the formation of widely spaced myelin, a peculiar feature encountered in human peripheral nerve disorders with circulating anti-myelin monoclonal IgM. In nerves treated with anti-MAG IgM ultrastructural myelin alterations were concurrent with activation of the rabbit's own C to the formation of TCC. Contrary to the immunological and ultrastructural findings obtained in C-sufficient animals, in C6-deficient rabbits injected with anti-MAG IgM no myelin alterations nor C completion were observed. This study identifies anti-MAG IgM as the mediator and the C as the effector of myelin changes observed in the present model and, for extension, in human neuropathies associated with anti-MAG IgM.

Abstract
Immunostaining of human, bovine and rodent unfixed nervous tissue sections was performed in order to characterize the structures recognized by anti-glycolipid antibodies. Four human sera from patients, two with M-IgM and motor neuron syndrome or motor neuropathy and two with motor neuropathy and polyclonal IgG antibody activity against gangliosides (GL; i.e. GM1, GD1b, GD1a), were utilized. Serum from a patient with sensory neuropathy and M-IgM immunoglobulins with antibody activity against sulfatide (SUL) was included in this series. This study shows that polyclonal and monoclonal anti-glycolipid antibodies give three different patterns of staining. The first is cholera toxin-like showing a more restricted neuronal pattern of staining. The second is peanut agglutinin-like, which includes the carbohydrate epitope shared by a group of glycoproteins in the gray and white matter. The third (anti-SUL) gives a preferential myelin staining. However, sera with anti-GM1 and anti-SUL antibodies recognize a number of closely situated determinants in the gray matter of the spinal cord and in the granule cells, while in peripheral nerves or in neuronal cells in culture their binding produces a different pattern (nodes of Ranvier for anti-GL; myelin for anti-SUL). These findings indicate that immunohistochemistry with anti-GL and anti-SUL antibodies may provide information regarding the glycolipid-bearing anatomical structures as target antigens and further substantiate the role of these molecules in the pathogenesis of autoimmune neurological disorders.

Abstract
We report the occurrence of a progressive neurological syndrome clinically characterized by subacute motor neuropathy in offspring of C6 deficient rabbits. On the basis of the pedigree analysis, the disease appears to be genetically transmitted, most probably with an autosomal recessive mode of inheritance. Pathological studies of affected animals revealed: transmitted, most probably with an autosomal recessive mode of inheritance. Pathological studies of affected animals revealed: 1) severe axonal degeneration in the sciatic nerve system involving mainly motor fibers; 2) occasional peripheral axonal enlargement closely associated with axonal degeneration; 3) presence of structured abnormal material in normal-size myelinated fibers of central nervous system (CNS) and peripheral nervous system (PNS); and 4) widespread occurrence of dystrophic axons and axonal spheroids in the gray matter of CNS. By ultrastructural examination, dystrophic axons are filled with tubulovesicular material, stalks of parallel membranes and dense bodies similar to what is described in human neuroaxonal dystrophies (NAD). The disease manifested by C6 deficient rabbits may represent an animal model of primary human NAD.

Abstract
We investigated the role of complement in the pathogenesis of the demyelinating polyneuropathy that occurs in some patients with IgM monoclonal gammopathy. Seven patients with chronic sensorimotor polyneuropathy and IgM monoclonal gammopathy were examined. In six patients, the monoclonal protein recognized an epitope shared by myelin-associated glycoprotein and two peripheral-nerve glycolipids, whereas in one patient, IgM bound to an unidentified myelin antigen. Direct and indirect immunofluorescence and immunoperoxidase assays showed colocalization along the myelin sheaths of peripheral-nerve fibers of monoclonal protein with complement components C1q, C3d, and C5. In addition, terminal-complement complex that was not associated with S protein was detected in myelin sheaths. It appeared that alterations in myelin geometry caused by the separation of myelin lamellae corresponded to sites at which terminal-complement complex was deposited. We conclude that demyelination in polyneuropathy associated with IgM monoclonal gammopathy may be mediated by complement.

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.

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.
