僵人综合征的临床及电生理特点 总被引:1,自引:0,他引:1
目的探讨僵人综合征的临床及电生理特点。方法分析3例患者的临床资料,并结合文献阐述该病的临床表现、电生理特点、治疗及预后。结果僵人综合征以进行性波动的肌肉僵直和肌痉挛为特点,易由内外刺激诱发,醒时出现,入睡后减轻或消火。肌电图均特征性地表现为持续性运动单位发放。僵肢综合征为僵人综合征的变异型,多表现为肢体远端强直及痛性痉挛,躯干相对较少累及。僵人综合征患者血和脑脊液中存在谷氨酸脱羧酶抗体。结论僵人综合征是一种自身免疫疾病。诊断僵人综合征需结合临床表现及特征性的肌电图改变。用丙种球蛋白及安定类药物治疗有效。 相似文献

We present the case of an 81-year-old female with severe rigidity, stiffness and superimposed muscle spasms that represents the oldest reported patient with progressive encephalomyelitis with rigidity and myoclonus. Two associated autoimmune disorders (diabetes mellitus and Hashimoto's thyoiditis) were recently diagnosed. A paraneoplastic origin was excluded. The spectrum of differential diagnoses including classic Stiff-Person syndrome and paraneoplastic Stiff-Person syndrome is discussed. 相似文献

The stiff man and stiff man plus syndromes 总被引:7,自引:0,他引:7
Rigidity in the setting of continuous motor unit activity at rest can be caused by a variety of central and peripheral conditions.
A central origin is suggested by the presence of painful reflex spasms. Focal spinal lesions and infective causes are relatively
easily excluded through imaging, microbiological and serological studies. There then remain a group of patients who may have
the classical ‘stiff-man syndrome’ or a related syndrome. When strict diagnostic criteria are used, patients with the stiff
man syndrome uniformly have axial rigidity, and about 90% are found to have antibodies against glutamic acid decarboxylase.
Treatment response and prognosis are excellent. Stiff persons with ‘plus’ signs, particularly those with rigidity of a distal
limb, are unlikely to have the classical stiff man syndrome. They have a poorer treatment response and prognosis. Some have
a paraneoplastic aetiology, while a non-malignant autoimmune basis seems likely in others. Those in whom post-mortem pathology
findings are available usually are seen to have had an encephalomyelitis with prominent involvement of the grey matter. Clinically,
stiff persons with ‘plus’ signs may be divided into three groups according to the aggressiveness of the pathology and its
relative distribution. Encephalomyelitis with rigidity follows a relentless subacute course, leading to death within 3 years.
Chronic cases may present with predominantly brainstem involvement, including generalised myoclonus (the ‘jerking stiff person
syndrome’) or spinal cord involvement, dominated by stiffness and spasm in one or more limbs (the ‘stiff limb syndrome’).

The anti-Hu antibody (HuAb) is directed against RNA-associated neuronal proteins and is known to cause paraneoplastic encephalomyelitis/sensory
neuronopathy syndrome mostly when associated with small cell lung cancer (SCLC). Paraneoplastic encephalomyelitis/sensory
neuronopathy syndrome with concurrent autonomic neuropathy has been reported to occur in paraneoplastic syndromes, although
its occurrence concomitant with acute pandysautonomia is less frequent. The authors describe the clinical, neuropathologic,
and serologic features of two cases with an anti-Hu-related paraneoplastic syndrome presenting with progressive autonomic
neuropathy. Both patients showed features of dysautonomia, including postural dizziness, abdominal pain, and diarrhea, and
symptoms of sensory neuropathy. Investigations disclosed severe sensory and autonomic neuropathy and positive HuAb titers.
The disease of patient 1 had a very rapid progression, and the patient died of cardiac arrest within 2 months of the onset
of symptoms. The autopsy revealed SCLC. In contrast, the disease of patient 2 had a less aggressive course. An extensive tumor
search disclosed SCLC only 28 months after onset of symptoms, and the patient died 1 month later of cardiorespiratory arrest.
Autopsies in both cases showed inflammation involving the intermediolateral columns and the dorsal root ganglia. These two
cases illustrate the association of early dysautonomia with HuAb-related paraneoplastic syndrome and the variations of clinical,
neuropathologic, and serologic findings in these types of cases. 相似文献

Multiple nerve enlargements at non-entrapment sites are usually caused by hereditary or acquired immune-mediated neuropathies.We describe a case of multifocal hypertrophic mononeuropathies detected by nerve sonography with a clinical picture of progressive mononeuritis multiplex caused by a paraneoplastic syndrome associated with anti-Hu antibodies. This case illustrates an unusual but important paraneoplastic differential diagnosis of progressive multifocal hypertrophic neuropathies. It emphasizes the role of nerve ultrasound in the diagnostic work-up of peripheral nervous system disorders. 相似文献

Symptomatic paraneoplastic neurological syndromes are rare manifestations of cancers. Recently, a new type of encephalitis associated with antibodies against NMDA-glutamate receptors (A-NMDAR) was defined. The patients, usually young women, present with acute onset of psychiatric symptoms and decreased consciousness. We describe the case of a patient who presented with acute onset of delirium alternating with sub-comatose state. Blood analyses were within normal range. Lumbar puncture showed lymphocytic pleiocytosis. Brain gadolinium injected MRI, brain and full body PET scans were normal. Investigations led to suspect a paraneoplastic syndrome and a right ovarian teratoma and A-NMDAR were found and the teratoma removed. The remaining sequellae included a cerebellar syndrome seldom described before. As cerebellar and cortical neurons share the same excitatory pathway through NMDA-glutamate receptors, the cerebellar function impairment observed in our patient could be explained by a disabling action on glutamate NMDAR by the A-NMDAR. 相似文献
