sweating is preserved and becomes exaggerated in some instances
FACIAL FLUSHING AND SWEATING MEDIATED BY THE SYMPATHETIC NERVOUS SYSTEM
Department of Neurology,Prince Henry Hospital Sydney, New South Wales, Australia
It is concluded that the cervical sympathetic outflow is the main pathway for thermoregulatory flushing and emotional blushing and that diminution or absence of such vasodilator reactions is a usual component of Homer's syndrome unless the responsible lesion is confined to the first thoracic root. Gustatory vasodilatation and sweating is preserved and becomes exaggerated in some instances.

• No systematic reviews, meta-analyses, or clinical trials that evaluated the
effectiveness of endoscopic thoracic sympathectomy for treating facial
blushing were identified. However, we have identified four case series
related to the request.
• The four case series were not critically appraised because they are prone
to bias and have significant methodological problems. These studies
represent level IV evidence according to the NHMRC criteria and one
should not draw firm conclusions from their findings.
• To date, the benefits or side effects associated with endoscopic thoracic
sympathectomy for treating facial blushing have not been properly
evaluated and reported. (Mia: there has been no evaluation since this report was completed in 2001, and the surgery is being performed without clinical evidence regarding safety and effectiveness! In Australia, it is listed on MBS, nobody is able to explain on the basis of what or which finding has it been included.)
• Further research using a well-designed controlled trial is warranted to
assess the efficacy of endoscopic thoracic sympathectomy for treating
facial blushing.

Received 1 February 1999; revised 17 May 1999; accepted 21 May 1999. Available online 30 November 1999.
Background: Several epidemiologic and clinical factors have been shown to predict long term outcome in major depressive disorder (MDD). The value of biological predictors has not been extensively studied. This study examined whether plasma norepinephrine may be useful in predicting outcome in MDD.
Methods: Forty patients were followed up 8 years after an index major depressive episode. Three outcome variables were assessed: time to first recurrence (the primary outcome measure), the Lee and Murray criteria and the Depression Outcome Scale (DOS). The results were examined against plasma norepinephrine value, at the index episode, using survival analysis and linear regression.
Results: High plasma norepinephrine at the index episode was positively and significantly associated with time to first recurrence for patients with nonpsychotic MDD (n = 31, χ2 = 8.38, on 1 df, p < .01). Similarly, plasma norepinephrine was significantly associated with good global outcome, both using Lee and Murray criteria (n = 34, adjusted R2 = .24, p < .01) and DOS criteria (n = 31, adjusted R2 = .17, p < .01) for this group of patients. In contrast, plasma norepinephrine was not significantly related to outcome for MDD with psychotic features.
Conclusions: Plasma norepinephrine at index episode seems to be a predictor of outcome in MDD.

ABSTRACT. Sympathetic hyperactivity plays an important and distinct role in hypertension associated with chronic renal failure (CRF). Renal ischemia, elevated angiotensin II, and suppressed brain nitric oxide (NO) all stimulate sympathetic activity. Evidence is accumulating for a role of sympathetic hyperactivity in renal and cardiac damage in patients with CRF.Carotid distensibility, baroreflex sensitivity, and orthostatic stress

Carotid distensibility, baroreflex sensitivity, and orthostatic stress

Submitted 5 November 2004 ; accepted in final form 22 February 2005
In this study, we tested the hypothesis that carotid arteries undergo rapid changes in distensibility on moving from the supine to head-up tilt (HUT) postures and, subsequently, that this change in carotid distensibility (cDa) might be associated with concurrent reductions in cardiovagal baroreflex sensitivity (BRS). Thus the effect of posture on carotid vascular mechanics and cardiovagal BRS with consideration for altered central hemodynamics (i.e., stroke volume; Doppler ultrasound) was examined. Carotid pulse pressure (cPP; Millar transducer) and contralateral B-mode ultrasound images were assessed at the carotid artery during supine and 60° HUT postures. From these measures, cDa was calculated at 5-mmHg pressure increments experienced during the cardiac cycle (n = 6). cPP (n = 9) was not different in the two postures. A smaller stroke volume being ejected into a smaller carotid artery in HUT explained the maintenance of cPP in HUT. Also, compared with supine, cDa was reset to a lower level in HUT (main effect of posture; P <> BRS (sequence method) was diminished in HUT vs. supine (P < 0.05). A positive correlation was observed between the tilt-induced changes in maximal cDa (in early systole) and cardiovagal BRS (r2 = 0.75; P <> between changes in cPP, systolic vessel dimensions, or average cDa and the corresponding change in BRS. The present results indicate that HUT elicits rapid changes in carotid artery mechanics and further suggest that reductions in the maximal cDa measured in early systole contribute to reduced cardiovagal BRS with HUT.
Patients with a history of sympathectomy were also excluded.

OBJECTIVE: To determine whether the cause of sympathetic dysfunction is due to increased regional sympathetic outflow or receptor supersensitivity to circulating catecholamines in the pathogenesis of reflex sympathetic dystrophy in hemiplegia. METHOD: Ten hemiplegic patients with reflex sympathetic dystrophy were instructed to refrain from smoking or using caffeine and alcohol, and medications that influence catecholamine metabolism were witheld for 24 hours before blood sampling. Patients with cardiovascular disease, diabetes or abnormal liver and renal function tests were excluded from the study. Patients with a history of sympathectomy were also excluded.

We observed an increased blood flow but an unchanged vasoconstrictor response in the affected hand in stage 1 of the disorder, but in stage 2 there was a decreased blood flow and a stronger vasoconstriction following an inspiratory gasp. These results suggest that in RSD patients the sympathetic nervous system function is altered and is different in the various stages.

rhinitis significantly affect nasal airflow
During sleep there is a discrete fall in minute ventilation and an associated increase in upper airway resistance. In normal subjects, the nasal part of the upper airway contributes only little to the elevation of the total resistance, which is mainly the consequence of pharyngeal narrowing. Yet, swelling of the nasal mucosa due to congestion of the submucosal capacitance vessels may significantly affect nasal airflow. In many healthy subjects an alternating pattern of congestion and decongestion of the nasal passages is observed. Some individuals demonstrate congestion of the ipsilateral half of the nasal cavity when lying down on the side. Nasal diseases, including structural anomalies and various forms of rhinitis, tend to increase nasal resistance, which typically impairs breathing via the nasal route in recumbency and during sleep. A role of nasal obstruction in the pathogenesis of sleep-disordered breathing has been implicated by many authors.

Loosing Nerves - article in Time Magazine, 1947
Sympathectomy, cutting of the sympathetic nerves, is causing the most violent arguments of all. The operation is now prescribed for a wide variety of ailments, from excessive sweating to high blood pressure. Nobody knows how many thousands of sympathectomies surgeons perform each year; there are an estimated 1,000 in Manhattan alone. Admittedly the operation is a life-saver in many cases of gangrene, angina pectoris, hypertension. But some sympathectomies may make men sterile. And because a sympathectomy reduces pain, some doctors consider it insidiously dangerous, e.g., a patient could have a perforating ulcer without pain. The experts agree that sympathectomy, like the other nerve-cutting operations, is getting out of hand.

Rhinitis - relative nasal sympathetic hyposensitivity
The exact pathophysiology of intrinsic rhinitis is not fully understood. The generally held belief is that it is due to an imbalance between the outflow of the nasal sympathetic and parasympathetic nervous systems, perhaps due to excessive parasympathetic or reduced sympathetic activity. In this study the nasal airway response to a predominantly sympathetic stimulus, isometric exercise, was studied in 19 patients with intrinsic rhinitis and compared with 16 normal patients.
The study shows that there is an abnormal response to isometric exercise in intrinsic rhinitis, perhaps due to relative nasal sympathetic hyposensitivity.

unavoidable consequence of sympathectomy
Pathological gustatory sweating and flushing can develop after injury to preganglionic cervico-thoracic sympathetic fibres, an unavoidable consequence of resecting that part of the sympathetic chain. The mechanism of this abnormal response is uncertain; conceivably, though, regeneration of injured salivatory fibres or collateral sprouting from nearby intact fibres creates aberrant connections between salivatory fibres and denervated vasomotor and sudomotor neurons in the superior cervical ganglion.(7) Commands to salivate would then be translated into commands to sweat and flush in the distribution of sympathetic denervation. Cross-innervation lower down in the stellate ganglion can also produce unusual and potentially distressing autonomic disturbances in the sympathetically-denervated arm (e.g., piloerection while eating).(8)

Sweating = supersensitivity to neurotransmitters and not sympathetic overactivity
These findings do not support the widely held view that autonomic disturbances in reflex sympathetic dystrophy are due to sympathetic overactivity. Rather, they suggest that sweating and changes in peripheral blood flow result from supersensitivity to sympathetic neurotransmitters. After injury, supersensitivity to noradrenaline may also contribute to spontaneous pain and allodynia by disrupting efferent sympathetic modulation of sensation. This would explain why pain and allodynia are relieved by sympathetic blockade, and why noradrenaline rekindles pain in sympathectomized skin.

We aimed to confirm whether a significant bradycardia was constant and only dependent on the right side. METHODS: We performed 24-hour Holter electrocardiographic recordings in 12 patients referred for bilateral sympathectomy. Surgery was performed at two distinct times allowing for the study of the consequences of unilateral right and bilateral sympathectomy. RESULTS: Heart rate was 77 +/- 8 beats per minute before surgery on the 24-hour recording and significantly decreased after bilateral (67.8 +/- 6.5 beats per minute; p < size="5">Patients should be informed of the bradycardia resulting from sympathectomy.

The degree to which perceptual awareness of threat stimuli and bodily states of arousal modulates neural activity associated with fear conditioning is unknown. We used functional magnetic neuroimaging (fMRI) to study healthy subjects and patients with peripheral autonomic denervation to examine how the expression of conditioning-related activity is modulated by stimulus awareness and autonomic arousal. In controls, enhanced amygdala activity was evident during conditioning to both "seen" (unmasked) and "unseen" (backward masked) stimuli, whereas insula activity was modulated by perceptual awareness of a threat stimulus. Absent peripheral autonomic arousal, in patients with autonomic denervation, was associated with decreased conditioning-related activity in insula and amygdala. The findings indicate that the expression of conditioning-related neural activity is modulated by both awareness and representations of bodily states of autonomic arousal.
Neuroendocrine regulation of autoimmune/inflammatory disease
- J Endocrinol. 2001 Jun;169(3):429-35.
Neuroendocrine regulation of autoimmune/inflammatory disease.- Recent studies indicate that physiological levels of glucocorticoids are immunomodulatory rather than solely immunosuppressive, causing a shift in patterns of cytokine production from a TH1- to a TH2-type pattern. Interruptions of this loop at any level and through multiple mechanisms, whether genetic, or through surgical or pharmacological interventions, can render an inflammatory resistant host susceptible to inflammatory disease.
- These interactions have been clearly demonstrated in many animal models, across species, strains and diseases, and are also relevant to human inflammatory, autoimmune and allergic illnesses, including rheumatoid arthritis, systemic lupus erythematosus, Sjogren's syndrome, allergic asthma and atopic skin disease.

the australian story
of ETS in Australia. Morgan and FFSO have researched continually for evidence of side-effects
with ETS/ESB. Patients have shared their personal and private stories on this site and the boards.
Surgeons such as Dr T and Dr Lin have admitted there are side-effects. Together we have worked as
a team and finally there is promising news. I have just received a letter from the 'Australian Safety
and Efficacy Register of New Interventional Procedures - Surgical' and they will "undertake a
systematic review of [ETS]" and "warrant it urgent attention".
note: ASERNIP-s did not review Sympathectomy and even after repeated letters and complaints from affected patients, failed to inform the Health Minister or initiate the review. Sympathectomy is listed on the MBS, even though there has been no study into the effects or the side-effect of the surgery - ever done and doctors admit, that they do not know how the patient will be affected. Sadly this admission always comes after they have performed the surgery.

In these studies, 26.3% or one quarter of patients with compensatory hyperhidrosis considered the complication major and disabling. The average time between surgical sympathectomy and the appearance of compensatory hyperhidrosis was 4 months (range 1-6 months). (82;93;118) The incidence of compensatory hyperhidrosis did not seem to be different after open or endoscopic approach. Irrespective of approach, two or more levels of denervation and removal of the stellate ganglion produced noticeably higher incidence.
We suggest that the
possibility of central contribution to the deregulation of sweat gland activity may be a substantial one and should constitute the subject of future research. Furthermore, our data suggest that the presence of a dysfunctional nervous system may constitute "vulnerability" to develop further neuropathic pain syndromes. Could this vulnerability be centrally mediated as well? What is the true nature of all other phenomena observed after sympathectomy (pathological gustatory sweating and what seems to be a rather innocuous complication, phantom sweating)? These and many other questions remain currently unanswered and should constitute similarly the focus of future
The study indicates that surgical sympathectomy, irrespective of operative approach and indication, may be associated with many and potentially serious complications.
note: There is no way for the surgeons who will end up with the disabling side-effect. Some of them attempt to guess, that it will be male and most of the time overweight. But there has been no research and there is no proof in the literature to support this claim. So who is a good candidate for ETS? There has been also no study into the severity of the side-effects, it is often the doctors or the patients who define. There is no objective study to establish the before and after state of these patients.

Chemical sympathectomy (CSX) reduced the corticosterone concentration slightly but the ACTH level increased significantly. When sympathectomy was combined with vagotomy (CSX+VGX) an increase in both corticosterone and ACTH levels was observed. Chemical sympathectomy and adrenalectomy (CSX+ADX) also produced a maximum decrease in corticosterone level and a maximum level of ACTH. Vagotomy (VGX) alone or together with CSX or ADX produced hyperglycaemia while chemical sympathectomy alone or together with adrenalectomy produced hypoglycaemia. In conclusion it could be stated that in rats in which vagotomy was performed singly and in combination with sympathectomy, glucocorticoid secretion increased along with increased corticosterone. Chemical sympathectomy alone or together with adrenalectomy reduced the corticosterone concentration in blood together with hypoglycaemic condition. ACTH concentration by and large was more when corticosterone secretion was decreased.

Substance P: In the central nervous system, substance P has been associated in the regulation of mood disorders, anxiety, stress, reinforcement, neurogenesis, respiratory rhythm, neurotoxicity, nausea / emesis and pain.
It also has effects as a potent vasodilator. This is caused by the release of nitric oxide from the endothelium. Its release can cause hypotension.

sympathetic nerves on early embryonic development and immune modulation of uterus
Role of sympathetic nerves on early embryonic development and immune modulation of uterus in pregnant mice
the CD4+/CD8+ T cells ratio significantly decreased, while the IL-2/IL-4 ratio significantly increased. These findings indicated that the activation of sympathetic nerves might be favorable to fetal survival and development during early pregnancy through influencing on immune function and decidua formation of uterus.
