[Peripheral autonomic nervous system function in patients with hypothalamic insufficiency].

Peripheral vegetative nervous system state was estimated in 61 patients with constitutional acquired hypothalamic insufficiency by using non-invasive methods. Control group consisted of 10 healthy individuals. Cardiovascular tests application led to the evaluation of subclinical parasympathetic vegetative insufficiency. In was more prominent in patients with early neuroendocrine disorders debut as well as in those with more protracted disease durations. The authors suggest that these findings testify the constitutional acquired character of disturbances. Besides it was also found the conductivity velocity fall in sudomotor preganglionic fibers in arms and legs and the prevalence of such disorders in patients with expressed dysraphic status. The last observation may testify the defect in laying of these peripheral vegetative fibers. The study carried out permits to suppose that subclinical peripheral insufficiency occur to be one of the factors evoking rise either of permanent (tachycardia, arterial pressure elevation, hyperhidrosis) or of paroxysmal vegetative disturbances (panic attacks, migraine) in patients with hypothalamic insufficiency.

[The clinical picture, diagnosis and therapy of headaches in patients with a hypothalamic syndrome].

190 patients with hypothalamic insufficiency were investigated. The character, frequency of various forms of headache as well as its correlation with neuroendocrine emotional motivation and vegetative disorders were analysed. It was found that headache occurred more frequently in patients with hypothalamic insufficiency (66%) than in the whole population (5-20%). This confirms the role of diencephalic disfunction in its genesis. Psychovegetative disturbances were expressed most of all in tension-type headache (TTH). Very likely that some psychoendocrine mechanisms (particularly depression and idiopathic edema) play important role in pathogenesis of TTH. Clinical effect of Lerivon confirms the pathogenetic role of depression in these cases.

State of the peripheral nervous system in patients with hypothalamic insufficiency.

An investigation was carried out by non-invasive techniques of the state of the peripheral nervous system in patients with a constitutional-acquired form of hypothalamic insufficiency. Ten healthy individuals were included in the control group. The presence of subclinical parasympathetic vegetative insufficiency was identified by cardiovascular tests. It was more marked in patients with an early onset of the neuroendocrine disturbances and longer course of the disease. In the opinion of the authors, this suggests the constitutional-acquired character of the vegetative disturbances. In addition, a slowing of the speed of conduction through the sudomotor preganglionic sympathetic fibers in the upper and lower extremities and the predominance of these disturbances in the group of patients with pronounced dysraphic status were identified. The latter suggests a defect of the laying down of these peripheral vegetative fibers. This investigation makes it possible to hypothesize that subclinical peripheral insufficiency is one of the factors governing the occurrence of both permanent (tachycardia, elevations of AP, hyperhidrosis) and paroxysmal vegetative disturbances (panic attacks, migraine) in hypothalamic insufficiency.
