Hyperhidrosis of palms and soles

Introduction Hyperhidrosis of the palm of your hand means that the patient has a significant excessive sweating. Systemic hyperhidrosis can be an abnormal physiological response, or a symptom of certain diseases. Local hyperhidrosis is most common in the palmar sac, which occurs symmetrically and is called hyperhidrosis of the palm. Most of the patients are teenagers. The cause is unknown and may be related to congenital factors. Hyperhidrosis of the palmar: It can be seen in various ethnic groups without significant gender differences. Most patients have a positive family history, often starting in infancy or childhood, and palmar sweating does not occur during sleep and quiet, nor Heat source stimulation, electrocardiogram abnormalities may occur in patients with excessive sweating, and there may be tachycardia or sharp waves, which may be related to unstable vasomotor. Generally no limitation or systemic associated disease. It is one of the symptoms and signs of hyperhidrosis. Hyperhidrosis is excessive sweating of the whole body or part of the skin. The causes of hyperhidrosis are generally classified into two types: organic diseases and functional disorders. Localized hyperhidrosis, often occurring in children or adolescence, can occur both male and female, and some have a family history that can last for several years, and there is a tendency to naturally reduce after 25 years of age. Physiological myeloid hyperhidrosis has a family genetic predisposition.

Cause

The causes of hyperhidrosis can be generally divided into organic diseases and functional disorders. The former are mainly found in endocrine disorders and systemic diseases such as diabetes, hyperthyroidism, hypertrophy, pituitary hyperfunction, congestive heart failure; neurological disorders such as concussion , hemiplegia, spinal trauma; tumors, such as metastatic tumor carcinoids; and infectious diseases such as malaria, tuberculosis, wave heat, and other functional hyperhidrosis, generally more spiritual sweating, such as high emotional stimuli such as mental stress, horror Caused by anxiety and anger.

Due to mental impairment or increased emotional impulses due to emotional impulses, increased secretion of acetylcholine and hyperhidrosis may also result in increased sweating due to increased sympathetic disturbances in sweat glands. Hyperhidrosis may occur in menstrual periods. Some genetic syndromes.

According to the clinical manifestations, the characteristics of hyperhidrosis can be diagnosed.

There is currently no uniform diagnostic criteria for hyperhidrosis. In 2004, John Hornberger of the American Dermatological Association organized a collaborative group of more than 20 unit experts to develop a diagnostic reference standard.

No obvious cause can be confirmed by visible hyperglycemia in the naked eye for more than 6 months and meet the following conditions:

(1) Symmetrical bilateral sweating sites.

(2) At least once a week.

(3) The age of onset is less than 25 years old.

(4) Have a positive family history.

(5) No sweat during sleep.

(6) Affect daily work and life.

If accompanied by fever, night sweats, weight loss, attention should be paid to the possibility of secondary hyperhidrosis.

Differential diagnosis

First, localized hyperhidrosis: often begins in children or adolescence, both men and women can have a family history, can last for several years, after 25 years of age, there is a natural relief tendency, the most common part of localized hyperhidrosis It is the palmar and rubbing surfaces such as the underarm, the groin, the perineum and the forehead nose and chest. The sweating of the palmar sputum can be sustained or transient, caused by mood fluctuations. There is no seasonal difference. The coldness of the hands and feet or even the convulsions often occur. The long-term can be accompanied by keratosis of the hands and feet. The sweating of the ankles can be induced by heat or mental activity. The excessive sweating of the underarm is caused by the excessive activity of the small sweat glands, which is not caused by the axillary odor.

Second, generalized hyperhidrosis: mainly due to other diseases caused by widespread sweating, like infectious hyperthermia, due to the regulation of the nervous system or oral antipyretic to sweat to dissipate heat. Other damages such as the central nervous system including the cortex and basal ganglia, the spinal cord or peripheral nerves can cause excessive sweating throughout the body.

According to the clinical manifestations, the characteristics of hyperhidrosis can be diagnosed.
