Every disease can be diagnosed.due to the manifestation of certain symptoms. Some of the illnesses known to mankind are named after the scientists who first discovered certain patterns. An example is the symptom of the tail. For the first time, he was described by the Austrian military therapist Franz (according to other sources Frantisek) Sr. Tailstock, who collaborated with other German neurologist Friedrich Schulz. It happened in 1876. A little later, a doctor from Austria, Nathan Weiss, came to the same description. That is why the symptom of Khvostek has the names-synonyms: the symptom Schulze - Hvostek, the symptom of Weiss.
The presence of manifestations of this disease in humans can be an indicator that in his body there is increased muscular excitability.
Features of the phenomenon
This spasmophilic symptom lies infairly rapid contractions of the muscles of the face, which occur when you hit a special hammer in the area of the so-called goose foot (in front of the trestle). Action data is produced in the area between the cheekbone arc and the corner of the mouth. This is where the facial nerve passes. When tapping with a hammer in this place, instantaneous contractions of the muscles of the mouth, nose, and the outer corner of the eye occur.
A symptom is not always considered positive, but onlyin the case when the contraction is involuntary and concerns the muscles of the eyelid (in some cases, twitching of the muscles of the upper lip can also be observed). To clarify the presence of a symptom, the procedure is repeated sequentially on both sides of the face.
The degree of manifestation of the symptom
There are three degrees of manifestation, in other words intensity, of a given symptom, which depend on the area of its spread.
- I degree or Hvostek-I. This degree is characterized by twitching of all the facial muscles, which are innervated by the facial nerve.
- II degree or tail of II. In this case, only the musculature of the lips, the area around the mouth and the nose is reduced.
- III degree or tail of III. It is considered the easiest degree at which you can see only the contraction of the muscles that are located in the corners of the mouth.
Under what diseases is the symptom positive?
This symptom can be decisive in the diagnosis of many diseases. For example, in combination with Trusso's symptom, it indicates the development of spasmophilia.
Tail Symptom can be positive in many diseases.
- Tetany - a clinical syndrome thatcharacterized by increased excitability of the neuromuscular system, which is expressed by periodic convulsions. With this disease, the symptom of the first degree of the first degree, that is the most severe, is most often observed.
- Tuberculosis is an infectious disease caused by mycobacteria.
- Epilepsy is a disorder of the nervous system that is chronic.
- Anemia is a condition of the body characterized by a low level of hemoglobin in the blood.
- Functional disorders of the nervous system.
- Bell's palsy (neuritis of the facial nerve).During its recovery period, there is a symptom of the Tailgate, a photo of which can be seen in this article. At this time, it is not recommended to carry out procedures that are aimed at stimulating the NA.
Symptom Chvostek spasmophilia
Spasmophilia, or tetany, is a disease withwhich symptom Khvostek expressed in its most severe form. This disease is characterized by carpopedal spasms, that is, when the hand is bent, and the thumb is almost completely brought to the palm. The facial muscles are very tense (the so-called titanic face). Cramps can last for several hours. In severe forms, they last 2 to 3 days, and are accompanied by rather painful sensations. Convulsions from the face can go to the larynx, which leads to the development of laryngospasm. With its prolonged continuation, loss of consciousness may follow.
In addition, there are increased excitability,emotional lability, sleep disorders, disorders of the cardiovascular system, gastrointestinal dyskinesia (violation of the tone and motility of the gastrointestinal tract).
The main indicator, after the determination of which the diagnosis is made, is a reduced level of calcium in the blood.
Symptom Chvostek thyrotoxicosis
This disease is associated with an increase in the amount of thyroid hormones in the blood. The reason, as a rule, are disorders of the thyroid gland, namely the enhancement of its functions.
Symptom Chvostek characteristic of thyrotoxicosismoderate severity, in other words, with its manifest form. The peculiarity of this stage lies in the expanded clinical picture, that is, symptoms can arise from almost all organs and systems, since the hormones produced by the thyroid gland are directly involved in all processes.
In complicated thyrotoxicosis, the symptom may be more pronounced, and irreversible changes are possible.
