Tarnovsky Sign

Tarnovsky sign: history and description

Tarnow sign is a term used in dermatology to describe the characteristic clinical picture that appears in certain skin diseases. This sign was described by the Russian dermatovenerologist Vladimir Mikhailovich Tarnovsky in the 19th century.

Vladimir Mikhailovich Tarnovsky (1837-1906) was a famous Russian dermatovenerologist and histologist. He has devoted his career to studying skin diseases and developing methods for diagnosing and treating them. In 1876, he published his observations of a characteristic clinical picture, which he called “Tarnovsky's sign.”

Tarnovsky's sign is a set of symptoms that appear in certain dermatological diseases. Characteristic features are:

1. Swelling and redness of the skin in the face and neck;
2. Itching and burning of the skin;
3. Formation of blisters and crusts on the skin;
4. Increased body temperature;
5. Weakness and fatigue.

Such symptoms can appear in various skin diseases, such as eczema, psoriasis, contact dermatitis and others. However, for an accurate diagnosis of the disease it is necessary to conduct additional studies and tests.

Thus, the Tarnowski sign is an important diagnostic criterion for some skin diseases. It allows doctors to quickly and accurately determine the cause of symptoms and prescribe appropriate treatment.

Tarnovsky sign (Vasily Mikhailovich Tarnovsky, 01.29.[02.10].1838 - 08/05/1915) is a differential diagnostic criterion for combined damage to the genital organs by tuberculosis and syphilis, as well as for suspected neurosyphilis. It was first described in 1876 by the Russian dermatologist V.M. Tarnovsky. The testes are predominantly affected - in half of the cases, the prostate gland - about one third of all cases, and less often - the seminal vesicles. Neurosyphilis can affect the mucous membranes of the oral cavity, salivary glands, eyes, skin and soft tissues.

Most patients with neurosyphilis experience neurological symptoms of varying severity. Neurological symptoms are most typical for extraspinal manifestations of neurosyphilis. It is registered in 46-84% of patients. Headache resembling a migraine pattern is observed in 30% of patients, vegetative crises - in 9%, epileptiform seizures - in 7%, progressive paralysis of the lower extremities - in 5-8% of patients.

Tarnovsky sign

**Tarnovsky sign** - test for the presence of parasites of the trematode family (flukes) in dogs and cats. This method was proposed by **V. M. Tarnovsky** in 1954. It is based on the fact that in this disease the enzyme teniidase is actively secreted, and it is proposed to check for this using traces of vomiting. If the feces, including vomit, are very smelly, then this sign is negative. If there is nothing on the stool, then one cannot draw conclusions about a parasitic disease. A negative result is not proof of denial of the presence of worms! A positive sign is a decrease in enzyme activity with corresponding changes in the bowel movement itself. This means that either the owner himself did not feed the animal and the enzymes are very low, or the disease is in the stage of “exhaustion” and the activity of the digestive system remains low.

__It is important to note that this method is popularly known as **“cat behavior after eating”**__. But in fact, it is aimed at determining the activity of intestinal enzymes secreted by parasites and allows one to predict the presence or absence of possible infection with parasites, and also allows one to decide on the initiation or continuation of treatment for parasites. In case of a disease that affects the intestinal microflora, enzyme activity is reduced.

Factors that increase the likelihood of animals becoming infected with parasites if their presence is suspected: - damage to the fur; - general exhaustion of the body; - bad feeling; - liquid stool.
