[The diagnostic significance of evoked cutaneous sympathetic potentials].

A study was made of evoked cutaneous sympathetic potentials in healthy persons, in simulation of emotional stress, in physical and orthostatic loads as well as during administration of 40 mg anapriline, 120 mg gangleron, and 15 mg diazepam. The purpose of the study was to identify factors that influence evoked cutaneous sympathetic potentials (ECSP). The mechanisms are reviewed of cutaneogalvanic reaction underlying ECSP. The data obtained were compared to those in patients with diabetes mellitus, Charcot-Marie amyotrophy, Guillain-Barré syndrome, Raynaud's disease, essential hyperhidrosis, panic attacks, and spinal amyotrophy. Analysis of ECSP makes it possible to reveal both brain function and primarily the presence of pathological alterations in the peripheral (segmental) autonomic nervous system.

[Cardiovascular tests in various forms of pathology].

Quantitative estimation of the status of the autonomic nervous system is a research priority in neurology. One of the approaches to its solving lies in the use of cardiovascular tests. The authors brief the mechanisms of the tests, provide their standards. Show the characteristic patterns of the cardiovascular tests in different diseases of both organic and psychogenic nature. Taking into consideration the simplicity, accessibility, and noninvasive nature of the tests, it is recommended that the cardiovascular tests may be employed for estimating the status of the autonomic nervous system in a wide range of diseases of both neurological and somatic origin.

[Electrophysiological analysis of the functions of the sweat gland fibers in various diseases].

The authors relate the data on vegetative sweating fibers studied by the method of evoked skin sympathetic potentials in patients with diabetes mellitus, Charcot-Marie atrophy, spinal amyotrophy, Guillain-Barre syndrome, essential hyperhidrosis, and in those with Raynaud's phenomenon and thyrotoxicosis. A remarkable decrease of conduction by sweating fibers was revealed in patients with diabetes mellitus, Charcot-Marie atrophy and Raynaud's phenomenon; a moderate decrease was shown by the patients with Guillain-Barre syndrome and by those with spinal amyotrophy. The conclusion is made about the high information content of the method.

[Evaluation of the autonomic innervation of the pupil].

The purpose of the study was to examine vegetative innervation of the pupil in different diseases associated and not associated with vegetative disorders. In addition to the ++clinico-neurological method, the main method of examination was to study the pupillary cycle (determination of the time of the pupillary cycle (TPC) with the aid of a slit lamp). Fifty healthy test subjects and 262 patients suffering from different somatic and neurologic diseases were examined. The patients were divided in 9 clinical groups: spinal amyotrophy, neural Charcot-Marie amyotrophy, Guillain-Barre syndrome, diabetes mellitus, thyrotoxicosis, hemicrania, Raynaud's disease, idiopathic hyperhidrosis, vegetative crises. The data obtained demonstrate varying grades of the rise of the TPC in the indicated diseases, which reflects varying degrees of vegetative innervation of the pupil insufficiency. However, no well-defined correlation was obtained between the intensity of the psychovegetative syndrome and the TPC. Therefore, it has been shown that the method of determining the TPC is unsophisticated and noninvasive and can be successfully used in different forms of pathology to identify vegetative insufficiency at different stages of the disease.

[The concept of "ganglionitis" in the modern science of the autonomic nervous system].

The authors review the concept of vegetative "ganglionitis" formed in the Soviet literature in the 40-60s. Consider the etiological, clinical and diagnostic aspects thereof. Provide the modern concepts of the clinical manifestations related to the lesions of the paravertebral sympathetic ganglia. Relate some hypotheses concerning the origin of painful phenomena within the framework of the syndrome of reflex sympathetic dystrophy. Indicate that verified lesions of the sympathetic ganglia are associated with well-defined clinical symptoms which absolutely differ in their appearance from the reported descriptions of "ganglionitis", which are unjustifiedly widely used in the Soviet literature over the recent decades. The conclusion is made about the necessity of reviewing the outdated concepts of the pathology of the vegetative sympathetic ganglia from the standpoint of the modern concept of peripheral vegetative insufficiency.
