1/105. amyotrophic lateral sclerosis in an adult following acute paralytic poliomyelitis in early childhood.About 30% of polio survivors develop a post-polio syndrome. Some of these patients develop slowly progressive muscle weakness known as post-poliomyelitis muscular atrophy (PPMA). We describe an unusual form of amyotrophic lateral sclerosis (ALS) in a patient with acute poliomyelitis in childhood. An 80-year-old woman had acute poliomyelitis at 2 years of age and developed weakness limited to the lower extremities. Residual weakness was stable until the age of 75 when she developed rapidly progressive weakness that first affected her left arm and subsequently the right arm. Neurological examination revealed both upper and lower motor neuron signs. These clinical features were more consistent with ALS than PPMA. At autopsy, there was marked atrophy of the precentral gyrus. Microscopic examination revealed a severe loss of all nerve cells and pronounced fibrillary astrocytosis of the lumbar ventral horns in the spinal cord, presumably a result of poliomyelitis. Superimposed on these spinal cord alterations were the pathological features of ALS, consisting of loss of Betz cells, corticospinal tract degeneration and loss of motor neurons of other levels of the spinal cord. The findings included some atypical features for ALS, namely, sparing of the hypoglossal nucleus, absence of Bunina bodies and absence of ubiquitin-immunoreactive inclusions. Although poliomyelitis and ALS may be coincidental, the unusual pathological expression of ALS raise the possibility that it is related to the antecedent poliomyelitis.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
2/105. Sporadic amyotrophic lateral sclerosis of long duration mimicking spinal progressive muscular atrophy: a clinicopathological study.We report an autopsy case of amyotrophic lateral sclerosis (ALS) clinically diagnosed as spinal progressive muscular atrophy (SPMA). The patient was a Japanese woman without hereditary burden. She developed muscle weakness of the distal part of the left lower extremity at age 42, followed by muscle weakness and atrophy of the right lower extremity and upper extremities. At age 57, she needed transient ventilatory support. Slight weakness in the facial muscles and fasciculation of the tongue appeared at age 60. At age 61, she died of sudden respiratory arrest. During the clinical course, neurological examination revealed neither Babinski signs nor hyperreflexia. The neuropathological examination revealed not only neuronal loss with gliosis in the facial nucleus, hypoglossal nucleus, and anterior horns of the spinal cord, but also loss of Betz cells and degeneration of the pyramidal tracts. Based on these clinicopathological findings and review of literature, we conclude that sporadic ALS mimicking SPMA is present.- - - - - - - - - - ranking = 1.5keywords = spinal (Clic here for more details about this article) |
3/105. amyotrophic lateral sclerosis with dementia. Case report.A patient is described in whom a profound and rapidly progressive dementia occurred in association with clinical features of amyotrophic lateral sclerosis. A magnetic resonance imaging showed signs of frontal and especially left temporal atrophy. The pattern of dementia indicated impaired frontotemporal lobe functions, evidenced by reduced tracer uptake in the frontotemporal lobes on brain single photon emission computed tomography. Neuropathological examination in this patient revealed mild frontotemporal atrophy with spongiform changes and neuronal loss affecting mainly layers II and III of the frontotemporal cortices. There was atrophy of the hypoglossal nuclei. The spinal cord changes were consistent with motor neuron disease. The patient showed an irreversible and progressive course. A review of the relevant literature was made.- - - - - - - - - - ranking = 0.25keywords = spinal (Clic here for more details about this article) |
4/105. Problems and pitfalls in the diagnosis of ALS.Although misdiagnosis of amyotrophic lateral sclerosis (ALS) is rare, it may be more difficult to make a diagnosis in some groups of patients than in others. If a patient presents in the later stages of the disease, only a small number of alternative diagnoses need to be considered. These include spinal muscular atrophies of adult onset, inclusion body myositis and motor neuropathies with conduction block. The latter group in particular may present a serious diagnostic problem, as several groups have recently reported patients suffering from lower motor neuron syndrome without detectable conduction block, who responded unexpectedly to treatment with immunoglobulins. As recent laboratory results suggest that a lengthy pre-clinical period may precede clinical ALS, there is increased pressure for clinicians to make an early diagnosis so that the maximum effect can be achieved from neuroprotective drugs. Thus, diseases such as distal motor amyotrophies, pressure palsies of motor branches of hand nerves, and cervical myelopathies, which can be differentiated mainly by their time-course, may be relevant in the differential diagnosis of ALS in some patients. During recent years, a few patients have been seen in our clinic who presented with pure motor deficits but later developed a more complex pattern of vulnerability suggestive of multisystem degeneration. The existence of patients with a disease that borders the spectrum of motor neuron diseases cannot be disputed. These patients include those carrying the Huntington mutation and those suffering from guam and new guinea disease ('ALS/PD'). From our experience, however, these 'difficult' diagnoses represent less than 10% of the patients seen in our clinic.- - - - - - - - - - ranking = 0.25keywords = spinal (Clic here for more details about this article) |
5/105. Numerous conglomerate inclusions in slowly progressive familial amyotrophic lateral sclerosis with posterior column involvement.A 59-year-old woman with slow progression of the loss of motor function and predominant lower motor manifestation during a 14-year period showed familial amyotrophic lateral sclerosis (fALS) with posterior column involvement, neuropathologically. Conglomerate inclusions (CIs) were observed in the remaining neurons in various areas, including the spinal anterior horn, posterior horn, Clark's column, accessory cuneate nucleus, tegmental reticular formation, motor nucleus of the trigeminal nerve, nucleus of the facial nerve, hypoglossal nucleus, medial nucleus of the thalamus, dentate nucleus, and motor cortex (Betz cells). Immunohistochemically, it was newly identified that the CIs showed marked immunoreactions with antibodies to phosphorylated and non-phosphorylated neurofilaments and to 64, 120, and 200 kD neurofilaments. The CIs were partially immunoreactive with the anti-ubiquitin antibody, although they reacted only weakly (or not at all) with anti-Cu/Zn superoxide dismutase (SOD1) antibody. Ultrastructurally, the CIs were comprised of neurofilaments. These data suggest that this case might have been different from an example of fALS with Ile 113 Thr mutation in the SOD1 gene.- - - - - - - - - - ranking = 0.25keywords = spinal (Clic here for more details about this article) |
6/105. Mother with amyotrophic lateral sclerosis and daughter with Creutzfeldt-Jakob disease.OBJECTIVE: To describe a mother who had autopsy-proved amyotrophic lateral sclerosis and her daughter who had clinically diagnosed Creutzfeldt-Jakob disease. DESIGN: case reports with molecular genetic analyses. SETTING: A tertiary care center. patients: The mother had progressive upper and lower motor neuron symptoms and signs starting at the age of 54 years. Electrophysiological testing supported the diagnosis of amyotrophic lateral sclerosis. autopsy results confirmed the diagnosis. Her daughter had received injections of human growth hormone prepared from pooled human pituitary glands as a child. At the age of 31 years, she experienced the onset of gait ataxia and dysarthria. cerebrospinal fluid showed the 14-3-3 protein. Cognitive difficulties ensued. She progressed to a nearly akinetic and mute state. She had overt visible fasciculations and muscle atrophy in the legs. MAIN OUTCOME MEASURES AND RESULTS: Neither patient carried a mutation in the prion protein gene. Both were homozygous for methionine at the polymorphic codon 129. Neither patient carried a deletion of the 5 exons of the superoxide dismutase 1 gene. CONCLUSIONS: It is uncertain whether the 2 cases occurred in the same family by chance or whether the patients shared genetic risk factors for the 2 diseases. The possibility that homozygosity at codon 129 is a risk factor for amyotrophic lateral sclerosis is being tested in a case-control study.- - - - - - - - - - ranking = 0.25keywords = spinal (Clic here for more details about this article) |
7/105. Accumulation of neurofilaments and SOD1-immunoreactive products in a patient with familial amyotrophic lateral sclerosis with I113T SOD1 mutation.OBJECTIVE: To report neuropathologic features of argyrophilic inclusions in the anterior horn cells, motor cortex Betz cells, and neurons of the medullary reticular formation, spinal posterior horn, and Clarke column in a Japanese case of familial amyotrophic lateral sclerosis with I113T substitution in exon 4 of the copper-zinc superoxide dismutase (SOD1) gene. methods AND RESULTS: These inclusions were stained pale pink on the hematoxylin-eosin stain and dark on the Bielschowsky stain. They were positive for antibodies to phosphorylated neurofilaments, ubiquitin, and SOD1. On electron microscopy, they consisted of abundant intermediate filaments of 10 to 20 nm in diameter with disordered array indicating neurofilaments. CONCLUSION: These findings suggest that the I113T mutation induces accumulation of neurofilaments and SOD1 in the central nervous system neurons.- - - - - - - - - - ranking = 0.25keywords = spinal (Clic here for more details about this article) |
8/105. motor neuron disease with predominantly upper extremity involvement: a clinicopathological study.We report two autopsy cases of motor neuron disease (MND) patients with an unusual type of muscular atrophy predominantly affecting the shoulder girdle and the upper extremities with proximal dominance. Both patients are considered to be clinically categorized into the El Escorial suspected form of amyotrophic lateral sclerosis (ALS). At autopsy, they showed marked loss of spinal anterior horn cells accompanied by astrogliosis positively immunostained with anti-glial fibrillary acidic protein antibody at the cervical level. At the lumbosacral level, anterior horn neurons were relatively well preserved and Bunina bodies, ubiquitin-positive skein-like inclusions and Lewy body-like inclusions were observed in the remaining neurons. In one patient, brain stem motor neurons (nerves V, VII, XII) and motor cortex, including Betz cells, were also affected and the corticospinal tracts were degenerated at the level of the thoracic and lumbar spinal cord. Pathological findings of this patient are consistent with those of ALS. In the other patient, the motor cortex, brain stem motor nuclei and the corticospinal tracts were well preserved, which is pathologically compatible with progressive spinal muscular atrophy. These patients with such a peculiar pattern of progressive muscular atrophy should be placed in a subgroup of ALS.- - - - - - - - - - ranking = 1.25keywords = spinal (Clic here for more details about this article) |
9/105. Autonomic failure in ALS with a novel SOD1 gene mutation.ARTICLE ABSTRACT: The authors report a patient with ALS and a novel SOD1 gene mutation who was in the totally locked-in state and developed autonomic failure followed by sudden cardiac arrest. A neuropathologic study showed widespread multisystem degeneration, including involvement of the autonomic nuclei in the medulla and spinal cord. SOD1 gene analysis detected a missense mutation of V118L in exon 4. These findings show notable phenotypic heterogeneity for SOD1-associated ALS.- - - - - - - - - - ranking = 0.25keywords = spinal (Clic here for more details about this article) |
10/105. amyotrophic lateral sclerosis with a 'pseudo-infarction' pattern on the electrocardiograph. A case report.amyotrophic lateral sclerosis (ALS) is a motor neuron disease involving both the upper and lower motor neurons in the brain stem and spinal cord. Although it is well known that various central nervous system disorders can produce a 'pseudo-infarction' pattern on the electrocardiogram, there have been no reports of this particular pattern in ALS patients. This report concerns an ALS patient who presented with an ECG pattern of S-T elevation followed by biphasic T and inverted T without any detectable myocardial abnormality. Data from the present case suggest that this pattern may be an inherent characteristic of ALS.- - - - - - - - - - ranking = 0.25keywords = spinal (Clic here for more details about this article) |
