Belsky: history of discovery and significance of the sign

Belsky's spot, also known as Filatova-Koplica spot or Filatova spot, is one of the early signs of measles disease. It was first described by the Russian pediatrician A.P. Belsky in 1884 and later independently confirmed by the American pediatrician N. Koplik and the Russian pediatrician N.F. Filatov.

Belsky is small whitish papules on the mucous membrane of the cheeks against the second lower molars. They appear in the initial stages of measles and can remain on the mucous membrane for several days after other symptoms have disappeared.

The discovery of Belsky's sign was of great importance for the diagnosis of measles, as it allows treatment to begin earlier and possible complications to be prevented. In addition, the Belsky sign helps distinguish measles from other infectious diseases that have similar symptoms.

Today, the Belsky remains an important diagnostic tool for pediatricians, used throughout the world. It is also an example of how collaboration between different countries and cultures can lead to significant medical discoveries.

In conclusion, Belsky's sign is a major discovery in the history of medicine and continues to play an important role in the diagnosis of measles. Its discovery and confirmation was the result of the work of several distinguished pediatricians from different countries, highlighting the importance of collaboration in science and medicine.

Belsky - these are Filatova - Koplik spots - these are small papules on the mucous membrane of the cheeks opposite the second molars in the initial period of measles.

Belsky-Filatov-Koplik spot (synonymous with Bell's spot) are small pale yellow nodules on the inner surface of the cheeks, localized near the molars of the lower jaw. Often these elements are confused with measles rashes. But in fact, the measles rash has a yellow tint and does not correspond to the location. Reference: M. Yu.
