Subacute onset of oculogyric crises and generalized dystonia following intranasal administration of heroin 总被引:3,自引:0,他引:3
A case is reported of a patient who experienced sudden onset of severe respiratory failure, shock and coma after first-time intranasal heroin abuse. During the following days full consciousness was restored, revealing persistent oculogyric crises, axial retropulsive dystonia and ataxia. Initially computer tomography (CT) scans of the brain were normal and cerebral spinal fluid examination showed a slight elevation of lactate. Magnetic resonance imaging (MRI) scans of the brain demonstrated diffuse bilateral subcortical white matter hyperintensities, with sparing of the U-fibres, symmetric bilateral hyperintensities of the globus pallidum and very hyperintensive subcortical foci in the right hemisphere. Differential diagnostic assessment, treatment, clinical and MRI course of a 6-month follow-up are discussed. 相似文献

Multiple sclerosis (MS) is widely accepted as a systemic T- cell-mediated autoimmune disease with a T-helper type-1 (TH-1) profile of cytokine production. We addressed the question whether interleukin-12 (IL-12), as a central mediator of TH-1-cell activities, is detectable in sera of MS patients, and if there is any association with disease activity. We analysed 171 sera of patients with MS and meningitis, and healthy controls. IL-12 p40 protein was detectable at low levels in MS patients (median 43 pg/ml) and controls (median 49 pg/ml). Analysing different disease courses and activities, a significant elevation in stable primary progressive MS cases compared with controls (median 66 pg/ml) was found. IL-12 p40 protein was not detectable in cerebrospinal fluid probes of 10 patients. We conclude that the function of IL-12 in MS depends on expression and degradation of the different proteins. These could act proinflammatory as well as limiting the disease process. Copyright Lippincott Williams & Wilkins 相似文献

To describe the clinical and neurophysiological spectrum and prognosis in a large cohort of biochemically and genetically proven late onset Pompe patients. Thirty-eight diagnosed with late onset Pompe disease at our neuromuscular department during 1985 and 2006 are described in detail. The mean delay from onset of symptoms or first medical consultation until diagnosis was 10.4 and 7.1 years, respectively. A different diagnosis was suggested in 11 of 38 patients. Ten patients underwent repeated muscle biopsies before diagnosis of Pompe disease was established. Limb girdle weakness was the most frequent presenting sign. Six patients complained of myalgia. Wolf-Parkinson-White syndrome was found in 3 of 38 patients. Respiratory failure preceded the onset of overt limb muscle weakness in three patients. The course of the patients was progressive in all, but there was a wide variety of progression, which did not correlate with the age of disease onset. In 71% of the patients, neurophysiological investigations revealed a myopathic EMG pattern, half of the patients had spontaneous activity including complex repetitive discharges. A normal EMG was found in 9% of the patients. Nerve conduction studies were normal in all. Pompe disease should be taken into consideration in patients with unexplained limb girdle muscular weakness with respiratory failure. Cardiac manifestations may not be restricted to infantile Pompe disease. 相似文献

We investigated the possible effect of age on the metabolism of androgens in muscle biopsies from patients with neuromuscular diseases. The conversion of testosterone, dihydrotestosterone (DHT) and 5-alpha-androstane-3-alpha-17-beta-diol (3-alpha-androstanediol) was measured in muscle biopsies from 24 patients with neuromuscular diseases and seven controls. The reductive metabolism of 3-alpha-HSDH was significantly higher than the oxidative metabolism. Significant metabolism of testosterone to DHT was not found. Only the age of the patients emerged as a significant negative predictor in a stepwise multiple linear regression model for V(max) and K(m) (Lineweaver-Burke plots) of the reductive metabolism of 3-alpha-HSDH. Therefore, altered metabolism of anabolic androgens in skeletal muscles could be demonstrated. We conclude that this could alter the androgenic catabolic/anabolic balance in the (androgenic target organ) skeletal muscle. 相似文献

The diagnosis of mitochondrial myopathy depends upon a constellation of findings, family history, type of muscle involvement, specific laboratory abnormalities, and the results of histological, pathobiochemical and genetic analysis. In the present paper, the authors describe the diagnostic approach to mitochondrial myopathies manifesting as extraocular muscle disease. The most common ocular manifestation of mitochondrial myopathy is progressive external ophthalmoplegia (PEO). To exclude myasthenia gravis, ocular myositis, thyroid associated orbitopathy, oculopharyngeal muscular dystrophy, and congenital fibrosis of the extraocular muscles in patients with an early onset or long-lasting very slowly progressive ptosis and external ophthalmoplegia, almost without any diplopia, and normal to mildly elevated serum creatine kinase and lactate, electromyography, nerve conduction studies and MRI of the orbits should be performed. A PEO phenotype forces one to look comprehensively for other multisystemic mitochondrial features (e.g., exercise induced weakness, encephalopathy, polyneuropathy, diabetes, heart disease). Thereafter, and presently even in familiar PEO, a diagnostic muscle biopsy should be taken. Histological and ultrastructural hallmarks are mitochondrial proliferations and structural abnormalities, lipid storage, ragged-red fibers, or cytochrome-C negative myofibers. In addition, Southern blotting may reveal the common deletion, or molecular analysis may verify specific mutations of distinct mitochondrial or nuclear genes. 相似文献

We monitored serum levels of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) before and during intravenously applied immunoglobulin (IVIG) therapy in 33 patients with chronic immune-mediated neuropathies and myopathies and 15 controls. Baseline MMP-2 and TIMP-2 serum levels were lower and MMP-9 and TIMP-1 serum levels higher in all patients compared to age-matched controls. Eight days after IVIG treatment, MMP-2, TIMP-2, and TIMP-1 serum levels increased, while MMP-9 serum levels decreased, indicating tissue repair. After 60 days, MMP-9 levels increased, MMP-2 approached normal levels, while TIMP-1 and TIMP-2 serum levels were below day 8 levels, indicating relapsing tissue damage. Comparing the MMP/TIMP results with the clinical courses, IVIG treatment tended to change MMP/TIMP levels in a way that paralleled clinical improvement and relapse. In sum, during a distinct time period, IVIG therapy seems to be able to modulate MMP-mediated tissue repair. 相似文献
