We tried to characterize the frequency and significance of manifestations of peripheral autonomic insufficiency (PAI) in clinical cases of acute inflammatory demyelinating neuropathies (AIDN). Forty patients with the above diagnosis (21 men and 19 women, 16 to 72 years old) were examined. To detect symptoms attributable to PAI, we used Birkmayer–Vein tables; these data were compared with the results of electroneuromyographic (ENMG) examinations. In 38 and 2 cases, clinical manifestations of AIDN corresponded to the Guillain–Barre and Miller–Fisher syndromes, respectively. According to ENMG data, changes in the peripheral nerves and neuromuscular junctions corresponded to axonopathy, myelinopathy, and a mixed damage (myelinoaxonopathy) in 18 (45%), 14 (35%), and 8 (20%) patients, respectively. The following disturbances in the sphere of autonomic control were observed: orthostatic hypotension, in 28 cases (70%); tachycardia in the resting state, in 24 cases (60%); hypertension in the reclining position, in 16 cases (40%); hypohydrosis of the skin on the limbs, in 18 cases (45%); dyspepsia, in 8 cases (20%), and enuresis, in 3 cases (7.5%). Manifestations of PAI began to be observed in the earliest stage of the disease and were preserved within the period of recovery of the motor functions; they were more intensive in the cases of a severe clinical course of polyneuropathies. The severity of autonomic disorders strictly correlated with the level of axonal degeneration (characterized according to the ENMG data). The treatment used (i.v. injections of immunoglobulin, plasmapheresis, use of vasoactive and neurometabolic drugs) not only improved the state of the motor sphere but also decreased the intensity of PAI symptoms. Thus, in the cases of AIDN not only thick myelinated fibers of the peripheral nerves but also a significant proportion of thin fibers responsible for the control of automatic functions are subjected to damage. PAI is rather frequently observed in patients suffering from AIDN, and the level of its manifestation reflects the severity of the disease and intensity of damage to the peripheral nerves. 相似文献

Thirty patients with various extrapyramidal movement disorders were treated for prolonged periods with 75 to 225 mg. daily of tetrabenazine. In patients with choreiform and hemiballistic motor activity the involuntary movements were diminished or abolished. In patients with cerebellar or Parkinsonian tremor the tremor was aggravated in moderately severe cases, but was uninfluenced in severe cases. In all cases the dyskinesia returned when- the drug was stopped.Side-effects were inconsiderable and disappeared on reducing the dose slightly. Hence the drug may be an important alternative to neurosurgical treatment of hyperkinesias and especially suitable for severely disabled patients. 相似文献

Knowledge on the genetics of movement disorders has advanced significantly in recent years. It is now recognized that disorders of the basal ganglia have genetic basis and it is suggested that molecular genetic data will provide clues to the pathophysiology of normal and abnormal motor control. Progress in molecular genetic studies, leading to the detection of genetic mutations and loci, has contributed to the understanding of mechanisms of neurodegeneration and has helped clarify the pathogenesis of some neurodegenerative diseases. Molecular studies have also found application in the diagnosis of neurodegenerative diseases, increasing the range of genetic counseling and enabling a more accurate diagno-sis. It seems that understanding pathogenic processes and the significant role of genetics has led to many experiments that may in the future will result in more effective treatment of such diseases as Parkinson’s or Huntington’s. Currently used molecular diagnostics based on DNA analysis can identify 9 neurodegenerative diseases, including spinal cerebellar ataxia inherited in an autosomal dominant manner, dentate-rubro-pallido-luysian atrophy, Friedreich’s disease, ataxia with ocu-lomotorapraxia, Huntington''s disease, dystonia type 1, Wilson’s disease, and some cases of Parkinson''s disease. 相似文献

Six male volunteers assumed either relaxed or unrelaxed postures, as defined by a Behavioral Relaxation Scale, in seven areas of the body. Electromyographic (EMG) levels in the muscle groups associated with each area were determined for both categories of postures. In all instances, the relaxed postures produced significantly lower EMG levels than the unrelaxed postures. This indicates that the Behavioral Relaxation Scale is a valid behavioral measure of relaxation. Also, it supports other studies which have shown that direct training in emitting relaxed postures is an effective means of achieving relaxation.This study was conducted in partial fulfillment of the M.A. degree by Jerry P. Maurer. Appreciation is expressed to Tz-Yi Jiang, Dr. Robert Lehr, and Jim Rice for their assistance. 相似文献

The electromyographic study of the subclavius muscle (SM) was performed in 31 different movements, in 12 subjects (10 male and 2 female) aged from 17 to 28 years. The action potentials were obtained with an electromyograph Teca TE 4. Our findings suggest that the SM acts mainly on the stability of the sternoclavicular joint; with more or less intensity according to the degree of the clavicular interaction with the movements of the peripheral parts of the superior limb. The SM seems to act as a substitute for the ligaments of the sternoclavicular joint. 相似文献

Extrapyramidal symptoms developed a variable time after the start of treatment with oral diazoxide in 15% of a series of 100 severely hypertensive patients. Six illustrative cases are described. Treatment with diazoxide could be continued in four of these. The symptoms are usually controllable either by dosage adjustment or by the use of diazepam or procyclidine. There was no evidence of irreversibility of the extrapyramidal syndromes observed. 相似文献

Clinical syndromes occasionally associated with or heralding cancer are summarized and classified.Some tumours present with manifestations of an endocrine or endocrine-like action; included in this group are thymomas, non-beta-cell tumours of the pancreas and carcinoids. Cushing''s syndrome, hypoglycemia, hypercalcemia, polycythemia and gynecomastia have been produced by a wide variety of tumours. Tumour emboli, non-bacterial thromboendocarditis and thrombophlebitis occasionally occur, but thrombophlebitis is not so frequent as was previously considered. Neurological syndromes are rare and show a great variety of presentations. Other occult manifestations of cancer include hypertrophic pulmonary osteoarthropathy, various skin diseases, obscure pyrexias and, in Hodgkin''s disease, pain secondary to alcohol consumption. 相似文献
