OBJECTIVES Patients diagnosed with axillary hyperhidrosis can face psychosocial issues that can ultimately hinder their quality of life both privately and socially. The routine treatment for axillary hyperhidrosis is T3-T4 sympathectomy, but compensatory sweating is a serious side effect that is commonly seen with this approach. This study was designed to evaluate whether a T3 sympathectomy was...

Accepted, May 29, 2002. OBJECTIVE: We sought to determine the long-term outcome of percutaneous stereotactic thermocoagulation for upper thoracic ganglionectomy and sympathectomy in patients with palmar and craniofacial hyperhidrosis with the use of a threedimensional system of coordinates for the location of the T2 and T3 ganglia on the basis of the findings in a cadaveric study. METHODS: From...

Kitchen, Amy M., Tadeusz J. Scislo, and Donal S. O’Leary. NTS A2a purinoceptor activation elicits hindlimb vasodilation primarily via a b-adrenergic mechanism. Am J Physiol Heart Circ Physiol 278: H1775–H1782, 2000.— Previously, we have shown that activation of adenosine A2a receptors in the subpostremal nucleus tractus solitarii (NTS) via microinjection of the selective A2a receptor agonist CG...

Guanethidine, a chemical that selectively blocks sympathetic noradrenergic neurons, was used to investigate the role of sympathetic innervation in the fertility of rat epididymal sperm, using both natural mating and in utero insemination protocols. This animal model correlates, at least in part, with spinal cord injury (SCI) in men. Adult male rats were treated daily by i.p. injections, for 21 ...

The role of endothelium-related factors in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage (SAH) has gained interest since the discovery of EDRF and of endothelin-1 (ET-1). The effect of SAH and both treatment of deferoxamine (DFO) and sympathectomy on endothelium-dependent vasodilation and ET-1-induced vasoconstriction of isolated rabbit carotid artery was examined using a...

We have attempted to evaluate the role of adrenergic nerves which arise from the superior cervical ganglia or which are intracerebral throughout their course, in the control of local cerebral blood flow (CBF). Hypothalamic blood flow (HBF) was measured in the conscious rabbit by the 133Xe-clearance technique. Stimulation of the upper brainstem, using 5-Hz, 3-V, 1-msec, square wave pulses, incre...

1. The pathogenesis of hypertension in spontaneously hypertensive rats (SHR) is considered to consist of neurogenic and non-neurogenic factors, both of which contribute to initiation and maintenance mechanisms. 2. Neurogenic factors have been demonstrated by the destruction of the central nervous system, sympathectomy, recording of sympathetic discharge, hind-limb perfusion and study of noradre...

The aim of the present study was to test the hypothesis that 3, 4-dihydroxyphenylalanine (DOPA) and dopamine (DA) in the gastrointestinal tract are to a large extent of exogenous origin and derived from food. Tissue concentrations of norepinephrine (NE), epinephrine (Epi), DA, DOPA, and 3,4-dihydroxyphenylacetic acid (DOPAC), as measured by reverse-phase HPLC with electrochemical detection, wer...

INTRODUCTION Primary hyperhidrosis is characterized by excessive sweating of the palms, soles, and axillae due to overactivity of the sympathetic nervous system at the level of the second and third sympathetic thoracic ganglia. The treatment of choice is bilateral dorsal sympathectomy performed using video-assisted thoracic surgery (VATS). The objective of our study was to determine whether lun...
