We have studied the frequency of human retrovirus antibody (HTLV-I, II, III) in the serum and CSF of patients with MS, matched controls, and patients with optic neuritis, idiopathic and postencephalitic Parkinson's disease, neuropathies, polymyositis, ALS, and postpoliomyelitis. Except for the postpoliomyelitis samples, all samples were collected prior to 1980. Contrary to a previous published report, no significant levels of antibody to HTLV-I, II, or III were found in the MS patients or controls. No retrovirus antibody was detected in patients with the other neurologic diseases.

To clarify the prognosis of patients with intractable diseases, a baseline survey of patients who received financial aid for intractable disease treatment between April 1984 and March 1985 was performed in Wakayama Prefecture, followed by a follow-up survey over a period of 8 years. Based on public welfare-subsidized system in Wakayama Prefecture, all patients with intractable diseases were checked up annually their certificates of financial aid for treatment. The results obtained were as follows: Parkinson's disease had the highest rate of discontinuation of medical care at 65%, followed by idiopathic thrombocytopenic purpura (ITP) at 64%, aplastic anemia at 55%, ulcerative colitis (UC) at 54%, and Behcet's disease at 50%. Systemic lupus erythematosus (SLE) had the lowest rate of discontinuation of medical care at 32%. Discontinuation was due to death in approximately 50% of the patients with SLE, scleroderma, dermatomyositis and polymyositis, and aplastic anemia. Of these, the causes of death in more than 50% were directly related to the primary diseases. However, in patients with SLE and aplastic anemia, 25% discontinued care because of cure or alleviation. Some patients remained in remission even though the prognosis for these diseases is not generally considered to be favorable. Transfer of jurisdiction to the Disabled Persons Welfare Act was seen in 28% of patients with Parkinson's disease, 24% with Behcet's disease, and 23% with ossification of posterior longitudinal ligament, diseases which are believed to cause restriction in daily activities of patients in some cases. On the other hand, cure or alleviation was the reason for discontinuation in 60-70% of patients with Buerger's disease, UC and ITP.(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of the present study was to verify the validity and potential application of oropharyngealesophageal scintigraphy in the analysis of neurogenic dysphagia. Scintigraphy was used on 36 patients divided into 2 groups: Group 1 (control) comprised 17 healthy volunteers; Group 2 included 19 patients suffering from various neurological and neuromuscular pathologies (myasthenia gravis, Parkinson's disease, polymyositis, stroke, paralysis of the last cranial nerves). In group 1 scintigraphy provided normal results both for mode of swallowing and transit, and for the values of the various parameters studied. On the other hand, scintigraphy showed that in group 2 all oral, pharyngeal and esophageal phases of swallowing were altered vs the controls with a statistically significant increase in the average values for the oral transit time (OTT) (1.45 sec., p = 0.0005), pharyngeal transit time (OTT) (3.23 sec., p = 0.044), esophageal transit time (ETT) e19.87 sec., p = 0.005) as well as in the corresponding bolus retention indexes ORU (12.95%, p = 0.0003), FIR (15.05%, p = 0.0003) and ERI (28.63%, p = 0.002). Moreover, the quality and means of swallowing also proved altered while tracheobronchial aspiration was only seen in 6 of the 19 patients (maximum value: 90%, average value; 7.66%) with a marked prevalence in the stroke subgroup (4/8). In light of these results and considering the low dose of radiation (0.00043 Gy), the lack of invasiveness and excellent tolerability, scintigraphy has confirmed its clinical validity in the functional, objective and quali-quantitative study of deglutition, even in patients suffering from neurogenic dysphagia.

p62, also known as sequestosome1, is a shuttle protein transporting polyubiquitinated proteins for both the proteasomal and lysosomal degradation. p62 is an integral component of inclusions in brains of various neurodegenerative disorders, including Alzheimer disease (AD) neurofibrillary tangles (NFTs) and Lewy bodies in Parkinson disease. In AD brain, the p62 localized in NFTs is associated with phosphorylated tau (p-tau). Sporadic inclusion-body myositis (s-IBM) is the most common progressive muscle disease associated with aging, and its muscle tissue has several phenotypic similarities to AD brain. Abnormal accumulation of intracellular multiprotein inclusions, containing p-tau in the form of paired helical filaments, amyloid-beta, and several other "Alzheimer-characteristic proteins", is a characteristic feature of the s-IBM muscle fiber phenotype. Diminished proteasomal and lysosomal protein degradation appear to play an important role in the formation of intra-muscle-fiber inclusions. We now report that: (1) in s-IBM muscle fibers, p62 protein is increased on both the protein and the mRNA levels, and it is strongly accumulated within, and as a dense peripheral shell surrounding, p-tau containing inclusions, by both the light- and electron-microscopy. Accordingly, our studies provide a new, reliable, and simple molecular marker of p-tau inclusions in s-IBM muscle fibers. The prominent p62 immunohistochemical positivity and pattern diagnostically distinguish s-IBM from polymyositis and dermatomyositis. (2) In normal cultured human muscle fibers, experimental inhibition of either proteasomal or lysosomal protein degradation caused substantial increase of p62, suggesting that similar in vivo mechanisms might contribute to the p62 increase in s-IBM muscle fibers.

Camptocormia is an abnormal truncal flexion posture that occurs while walking or standing. It is usually caused by various hypokinetic movement disorders such as Parkinson disease and multiple system atrophy. Myopathy or motor neuron disease can also be infrequent causes of camptocormia. Paraspinous muscle biopsy usually reveals focal myositis, regardless of the etiology of camptocormia. We describe the first case of generalized inflammatory myopathy with prominent camptocormia and proximal muscle weakness. Muscle biopsy of the quadriceps confirmed the diagnosis of polymyositis, and the posture showed modest improvement in response to steroid treatment.

Camptocormia (CC) is defined as a trunkal flexion which worsens while standing, sitting and walking and disappears in the supine position. CC is a well-known clinical phenomenon in patients with generalized neuromuscular disorders like polymyositis, myasthenia gravis or motor neuron diseases, and it is also described in the context of movement disorders like Parkinson's disease (PD) or multiple system atrophy. In association with PD, CC seems to be a rare symptom which occurs preferentially in late stages of the disease. Currently, there are 3 main hypotheses on the pathogenesis of CC in PD, i.e. a focal myopathy of the trunk muscles, axial dystonia and a drug-induced etiology. This review gives a synopsis and critical acclaim of these 3 etiologies and refers to the current study data and possible treatment strategies.

Camptocormia, an abnormal truncal flexion posture that occurs while walking or standing, is usually caused by various hypokinetic movement disorders, mainly Parkinson disease. We describe the case of a man with subacute onset of camptocormia. Quadriceps muscle biopsy showed significant rhabdomyolysis, few isolated inflammatory cells and mild expression of type I MHC in few fibers, a pattern usually found in immune-mediated necrotizing myopathies. Myositis was associated with Raynaud's phenomenon, mild sclerodactyly, and anti-Ku antibodies leading to the diagnosis of polymyositis/systemic sclerosis overlap myositis. The posture showed modest improvement in response to treatment.
