reduced sweating
Introduction
Introduction Sympathetic chain syndrome can manifest as symptoms of loss of function, such as reduced skin electrical conductivity and reduced sweating. Sympathetic chain syndrome is a clinical syndrome in which multiple causes cause long-term recessive existence. When the ganglion damage is severe and the compensatory ability is weakened, typical symptoms appear, which are often delayed in diagnosis and treatment, and are occasionally found in autopsy. Due to the different sympathetic ganglia, the clinical manifestations are not the same, but all have common clinical symptoms. Such as pain, sensory disturbances, vascular dysfunction, etc.
Cause
Cause
(1) Causes of the disease
Many causes can cause sympathetic chain syndromes, such as various acute and chronic infections, systemic or local infections, various endogenous and exogenous poisonings, as well as trauma, spinal degenerative diseases, tumors, vascular diseases and chronic Irritating lesions, etc.
(two) pathogenesis
This disease is caused by different sympathetic ganglia, which leads to the corresponding clinical manifestations. Pathological changes vary with the primary disease, caused by infectious inflammation, intracellular vacuolization and steatosis, with hyperplasia of the interstitial and surrounding tissues, edema and infiltration, poisoning and sepsis cause visible ganglion cell necrosis.

an examination
1. The disease can occur at any age, both sexes can occur, clinically not uncommon, because typical symptoms appear in the late stage, making the clinical diagnosis rate lower. Mostly subacute or chronic onset, can also be acute onset, usually have a tendency to turn to chronic prolongation, when the time is up. The basic characteristics of local sympathetic chain lesions are: segmental asymmetry and strong diffusivity and periodic aggravation. Due to different sympathetic ganglia, clinical manifestations are different, but all have common clinical symptoms. .
2. Pain and sensory disturbances: Pain is persistent or persistent, accompanied by increased seizures, heavy at night, mood swings, physical labor, weather changes and cold stimuli can all aggravate the pain, the range is more diffuse, and there is widespread spread. trend. The surface projection area of the damaged sympathetic ganglia may have tenderness. If the tender point is found, it often helps to locate the diagnosis. There may be various kinds of paresthesias, such as numbness, ant feelings, etc. The objective sensory disturbances are lighter than subjective symptoms, mostly painful abnormalities, and temperature abnormalities are less common, and tactile and deep sensory disturbances are less common.
3. Skin and appendage changes: The skin may have irritating symptoms, such as increased sweating and hyperactivity of the hair. It may also be characterized by loss of function, such as decreased skin electrical conductivity, reduced sweating, and reduced paroxysmal reflex. In addition, the skin may also have nutritional disorders, dryness and atrophy, hair loss and nails become brittle.
4. Vascular dysfunction: mainly manifested as small arteries and capillary vasospasm, but also vasotropia, even paralysis, and somatic neurological dysfunction.
According to the occurrence of paroxysmal or persistent pain in a lateral sympathetic innervation area, or obvious tenderness in the sympathetic ganglion projection area, the disease may be considered.
Diagnosis
Differential diagnosis
Sweating around the body: People's sweat glands are the most developed, and people's sweating can be divided into three types: warm sweating, spiritual sweating, and taste sweating. Sweating is a normal physiological phenomenon in the human body. Sweat can take away excess heat from the body and some metabolites such as uric acid and fatty acids. But there are also diseases that cause sweating. Excessive sweating can reduce the flow of blood circulation in the human body, and the circulation slows down, which causes the body's heat dissipation to decrease, resulting in an increase in body temperature. A lot of sweating can also cause the body's salt to be lost, and the cells are devastated by the lack of sodium.
Abnormal sweating: Sweating is the body's thermoregulation. When we feel hot, or during exercise, sweating can help the body reduce body temperature to normal levels through the evaporation of sweat. However, it is not a good thing that sweat is abnormal.
