[Clinico-electroneuromyographic characteristics of myelodysplasia in children].

Myelodysplasia is a topical problem of childhood neurology. The early diagnosis and treatment of myelodysplasia prevents the development of severe neurological symptomatology. Twenty patients with myelodysplasia were investigated using clinical, electroneuromyographic, and thermographic methods of examination. Electroneuromyography included determination of the bulbocavernous reflex which served as an objective criterion of the status of the lumbosacral portion of the spinal cord. Early diagnosis of myelodysplasia makes it possible to conduct preventive therapy including electrostimulation of the spinal cord or perform surgical intervention when indicated in children with this pathology.

[Effectiveness of the therapeutic use of complexones in various diseases of the extrapyramidal system in children].

The article is devoted to therapy of some extrapyramidal diseases related to accumulation of biomicroelements in the basal ganglia. Two clinical observations (Fahr's disease and Hallervodren-Spatz' disease) in children are described. In both cases therapy with complexones (xydifon, penicillamine, deferoxamine) combined with antioxidants, calcium antagonists, drugs improving the microcirculation, etc., produced a marked positive effect. This was the first case of using complexones for treating Fahr's disease. Possible ways of correcting the metabolism of trace elements in diseases affecting the central nervous system, in particular perspectives of wider application of complexones are discussed.

[Prospective and retrospective analysis of prognosis in perinatal hypoxic lesions of the brain].

The article presents data on the prospective and retrospective analysis of the dynamic structure of neurological syndromes in 211 children with perinatal hypoxic lesions of the brain in the preschool period. The complex of examinations included electroencephalography, echoencephalography, psychological examination, as well as measurement of lipid peroxidation products and immunoglobulin levels in the cerebrospinal fluid. It has been demonstrated that transformation of neurological symptom complexes at the most important stages of postnatal ontogenesis plays the decisive diagnostic and prognostic role. On the basis of the findings the authors consider optimal terms for screening children with a history of perinatal hypoxic impairment of the nervous system.

[Electroneuromyographic evaluation of the efficacy of vibrotraction treatment of patients with vertebrogenic lumbosacral radiculitis].

The authors compared the results of the treatment in patients with the neurologic manifestations of lumbar osteochondritis using vibrotraction with and without electrostimulation and in control patients treated without vibrotraction and electrostimulation. The electroneuromyographic examinations showed the best normalization of the electroneuromyographic parameters in patients receiving a multimodality treatment including the employment of medicamentous means of physiotherapy and also vibrotraction and electrostimulation. The use of the multimodality treatment reduced the period of the patients' work fitness recovery to a greater degree than other methods of therapy.

[Determination of the rate of spike conduction along sensory fibers of the proximal segment of the sciatic nerve by the technic of correlating the latency periods of the H-reflex, F-wave and M-response].

The author substantiates the possibility of calculating the speed of impulse conduction along the sensitive fibers of the sciatic nerve in the segment "the popliteal fossa- the spinal anterior horn" by recording over the musculus soleus the evoked H-reflex, F-wave and M-response and by measuring their latent periods. A formula to calculate the speed is offered. The results of examining clinically healthy people are presented.

[Clinical systematization and diagnosis of polyneuropathies].

The authors proposed a working scheme for the clinical classification of polyneuropathies according to which the latter ones are divided into primary idiopathic and combined hereditary forms, and secondary ones resulting from infectious, toxic, vascular, metabolic, and physical factors. The authors also worked out the clinical and electroneuromyographic criteria for the diagnosis (including the differential one) of the following disorders: Charcot-Marie's neural amyotrophy, the Roussy-Levy syndrome, sensory polyneuropathy with acroosteolysis, toxic vegetative polyneuropathies, and secondary lesions of the peripheral nervous system in patients with diabetes mellitus and collagenous diseases.

[Problem of amyotrophy].

Clinical and electroneuromyographic studies of 1771 patients with diseases of the nervous and neuromuscular systems revealed disruption of the trophic supply to the skeletal muscles in cases of damage to both the segmento-peripheral neuromotor apparatus and vegetative and somatic segmental and suprasegmental formations. Electroneuromyographic indicators of the amyotrophic process include a decrease in the amplitude of the maximal M-response and a reduced number of functional motor units. In hyperkinetic syndromes, a paradoxical elevation of these indices is observed, which seems to be associated with "an alleviating trophotropic effect" exerted by striatal system impairment.

[Clinicoelectroneuromyographic study of neuromuscular syndromes combined with connective tissue pathology].

An electroneuromyographic examination of 132 patients with pseudohypertrophic and myosclerotic forms of myodystrophies, collagenoses, mucopolysaccharidoses, Marfan's disease, and Chernogubov-Ehlers-Danlos' disease was carried out. A relationship between the duration of the M-response potential and the state of the interstitial connective tissue of the skeletal muscles was revealed. This duration appeared to be longer in cases of proliferation, sclerosis, and fibrosis of the interstitial tissue, and shorter in cases of a deficiency of the collagen fibres and increase of their elasticity.

[Hereditary areflexic dysstasia (Roussy-Lévy syndrome)].

Clinical and electroneurographic investigations of 22 cases of hereditary areflectory dysstasia (Roussy-Levy's syndrome). 20 cases of Charcot-Marie's neural amyotrophy and 8 cases of Friedreich's familial ataxia were carried out. In the patients with Roussy-Levy's syndrome, the speed of the impulse conduction along the peripheral nerves of the extremities, as well as the amplitudes of evoked potentials were lowered to the greatest extent: this was an evidence of nosological independence of the disease.

[Electroneuromyography in pediatric clinical neurology].

The diagnostic effectiveness of electroneuromyography in nervous and neuromuscular diseases at various periods of childhood is analyzed. The electroneuromyographic characteristics of the "floppy child" syndrome, natal traumatic humeral plexitis, syndromes of the strio-pallidar system affection and neuromuscular diseases are presented with reference to age.
