Surgery for hyperhidrosis abolished 6-sulphatoxymelatonin excretion

The amount of 6-sulphatoxymelatonin, the chief metabolite of melatonin, in the urine was measured in nine patients, who were subjected to bilateral sympathectomy at the second thoracic ganglionic level for treatment of hyperhidrosis of the palms.
All patients showed before surgery a normal 6-sulphatoxymelatonin excretion with a peak in the excretion during the night time. After the sympathectomy, the high night time excretion was clearly abolished in five patients but remained high in four patients. This indicates that the segmental locations of the preganglionic sympathetic perikarya in the spinal cord, stimulating the melatonin secretion in the pineal gland in humans, vary between individuals. An increase in daytime melatonin excretion was observed in the patients responding to the sympathectomy with an abolished 6-sulphatoxymelatonin rhythm. This increase could indicate that the final sympathetic neurons innervating the pineal gland might have a both stimulatory and inhibitory function.

Since melatonin, the hormone secreted from the pineal gland has a remarkable anti-oxidant property and whose rate of production declines with increase in age, has prompted many to suggest that this hormone plays a crucial role in the genesis of neurodegenerative diseases. Melatonin cannot only scavenges oxygen free radicals like super oxide radical (O2-), hydroxyl radical (*OH), peroxyl radical (LOO*) and peroxynitrite anion (ONOO-), but can also enhance the antioxidative potential of the cell by stimulating the synthesis of antioxidative enzymes like super oxide dismutase (SOD), glutathione peroxidase (GPX), and also the enzymes that are involved in the synthesis of glutathione. In many instances, melatonin increases the expression of m RNA's of the antioxidative enzymes. Melatonin administration has been shown to be effective in counteracting the neurodegenerative conditions both in experimental models of neurodegenerative diseases and in patients suffering from such diseases. A disturbance of melatonin rhythm and secretion also has been noted in patients suffering from certain neurodegenerative diseases. From all these, it is evident that melatonin has a neuroprotective role.

Parallels between effects of spinal cord injury and sympathectomy on cardiac function

Cardiac dysfunctions are common complications following SCI. Cardiovascular disturbances are the leading causes of morbidity and mortality in both acute and chronic stages of SCI. We reviewed epidemiology of cardiac disturbances after SCI, and neuroanatomy and pathophysiology of autonomic nervous system, sympathetic and parasympathetic. SCI causes disruption of descendent pathways from central control centers to spinal sympathetic neurons, originating into intermediolateral nuclei of T1-L2 spinal cord segments. Loss of supraspinal control over sympathetic nervous system results in reduced overall sympathetic activity below the level of injury and unopposed parasympathetic outflow through intact vagal nerve. SCI associates significant cardiac dysfunction. Impairment of autonomic nervous control system, mostly in patients with cervical or high thoracic SCI, causes cardiac dysrrhythmias, especially bradycardia and, rarely, cardiac arrest, or tachyarrhytmias and hypotension. Specific complication dependent on the period of time after trauma like spinal shock and autonomic dysreflexia are also reviewed. Spinal shock occurs during the acute phase following SCI and is a transitory suspension of function and reflexes below the level of the injury. Neurogenic shock, part of spinal shock, consists of severe bradycardia and hypotension. Autonomic dysreflexia appears during the chronic phase, after spinal shock resolution, and it is a life-threatening syndrome of massive imbalanced reflex sympathetic discharge occurring in patients with SCI above the splanchnic sympathetic outflow (T5-T6). Besides all this, additional cardiac complications, such as cardiac deconditioning and coronary heart disease may also occur.

Neurogenic shock is shock caused by the sudden loss of the autonomic nervous system signals to the smooth muscle in vessel walls. This can result from severe central nervous system (brain and spinal cord) damage. With the sudden loss of background sympathetic stimulation, the vessels suddenly relax resulting in a sudden decrease in peripheral vascular resistance (vasodilation)^[1] and decreased blood pressure.

Signs and symptoms

• hypotension
• bradycardia
• warm, dry extremities
• peripheral vasodilation
• venous pooling
• Poikilothermia
• Priapism Due to PNS stimulation
• decreased cardiac output (with cervical or high thoracic injury)

Mayo Clinic investigates the same disorder as the one resulting from the elective surgical sympathectomy

Autoimmune autonomic ganglionopathy is characterized by impairment of multiple autonomic domains of which sudomotor function is among the most common. Many patients with this disorder have difficulties with thermoregulation and anhidrosis.

Other alternative more selective methods, rather than cutting the main trunk should be studied

Compensatory sweating remains the most common, and most disabling complication of video-assisted thoracoscopic sympathectomy. Other alternative more selective methods, rather than cutting the main trunk should be studied thoroughly to assess their efficacy in reducing the complication of compensatory sweating.

Evidence: sympathectomy created imbalance of autonomic activity and functional changes of the intrathoracic organs

Surgical thoracic sympathectomy such as ESD or heart transplantation can result in an imbalance between the sympathetic and parasympathetic activities and result in functional changes
in the intrathoracic organs.
Therefore, the procedures affecting sympathetic nerve functions, such as epidural anesthesia, ESD, and heart transplantation, may cause an imbalance between sympathetic and parasympa-
thetic activities (1, 6, 16, 17). Recently, it has been reported that ESD results in functional changes of the intrathoracic organs.


In conclusion, our study demonstrated that ESD adversely affected lung function early after surgery and the BHR was affected by an imbalance of autonomic activity created by bilateral ESD in patients with primary focal hyperhidrosis.

sympathectomy significantly increased the ratio of patients exhibiting a positive response to methacholine

Of 46 patients who had a negative result for methacholine challenge preoperatively, 12 (26%) became positive after surgery. In terms of the level of sympathectomy, T3 sympathectomy significantly increased the ratio of patients exhibiting a positive response to methacholine (from 19% to 34%, respectively) (p < 0.005).
Conclusions. Thoracic sympathectomy can adversely affect lung function early after surgery, although the clinical significance is uncertain. It may also exert an influence on the development of bronchial hyperresponsiveness, especially when performed at the T3 level.

Compensatory Hyperhidrosis is a result of a lack of negative feedback to the hypothalamus after sympathectomy

"CH (compensatory hyperhidrosis) is a result of a lack of negative feedback to the hypothalamus after sympathectomy"

J. bras. pneumol. vol.34 no.11 São Paulo Nov. 2008

The authors of the article consider this to be more evident after T2 sympathectomy, but members of this forum (http://etsandreversals.yuku.com/directory) who have had the surgery performed at a lower level(s) have also experienced thermoregulatory dysfunction and severe/disabling lower body hyperhidrosis.
The article is important because it states clearly that sympathectomy will change the function of the hypothalamus, - part of the brain responsible for much more than thermoregulation. It also refers to the abnormal sweating as hyperhidrosis, indicating that it will be more that what the body needs for thermoregulation.

"The hypothalamus affects the endocrine system and governs emotional behavior, such as anger and sexual activity. Most of the hypothalamic hormones generated are distributed to the pituitary via the hypophyseal portal system.^[10] The hypothalamus maintains homeostasis; this includes a regulation of blood pressure, heart rate, and temperature."
http://en.wikipedia.org/wiki/Hypothalamus

When you sign the 'informed consent' document, you are not told that the surgeon is going to interfere with the system that maintains the body's homeostasis, and that loss of homeostasis leads to pathology. If you are not told this by your surgeon, then he/she is withholding information that would allow you to understand the nature and scope of the irreversible procedure your are agreeing to.
You are also told that the amount of sweat you will have on other parts of the body after surgery equals the amount of sweat on the palms before surgery. There is not truth to this claim, and no surgeon can substantiate this. The doctors KNOW that this is a lie, yet they tell this to the patients in order to make the surgery appear as a simple and safe and ...predictable.

If you have a procedure that is distinctly different than what you agreed to, your consent based on the information provided by your surgeon is void, meaning that you can argue your case in court that the procedure was performed WITHOUT consent, which constitutes 'trespass to a person' and battery. In this case (if you win), the court can bring a much harsher sentence on the (fraudulent) surgeon, and can award exemplary/aggravated damages in addition to your loss of earnings etc.

Cutaneous vasodilator responses induced by activation of hypothalamic heat loss mechanisms are completely abolished by sympathectomy

Effects of Sympathectomy on the mean decrease in HBF (Hypothalamic blood flow)

Intrahypothalamic injection of 0.1 mug of tyramine caused a mean decrease in HBF of 15.6 ml/100 g per min (P less than 0.001). This effect of intrahypothalamic injection of tyramine was abolished by bilateral cervical sympathectomy but not by chemical sympathectomy of the upper brainstem. These results support the idea that local CBF, at least in the hypothalamus, is mediated by two distinct pathways. The first consists of the sympathetic nerves which arise in the cervical ganglia, and which activate intrahypothalamic alpha-receptors to cause constriction. The second is an entirely intracerebral noradrenergic pathway which stimulates beta-receptors to cause vasodilation.

Cervical sympathectomy inhibits axonal transport of gonadotropin-releasing hormone during continuous exposure to light in male rats

Considering the action of colchicine, which inhibits axonal transport, it is suggested that cervical sympathectomy also inhibits axonal transports of GnRH between the GnRH neurons and the median eminence during continuous exposure to light.

Sympathectomy and parasympathectomy leads to the hyperfunction of the serotoninergic system and pathology

We studied the balance of activity of sympathetic, parasympathetic, and serotoninergic divisions of the autonomic nervous system in the regulation of the heart function in rabbits. High activities of the sympathetic and parasympathetic system are associated with antagonistic interactions between them. Moderation of activity of these systems could be accompanied by activation of the serotoninergic system. Physiological sympathectomy and parasympathectomy lead to hyperfunction of the serotoninergic system and pathology.
