Paul Kaznelson (1950)

Paul Kaznelson (born April 7, 1892 in Warsaw , Russian Empire , † 1959 ) was a Czechoslovak hematologist .

Life

Kaznelson was born as a Russian citizen in what was then the Russian province of Vistula . After the death of his father, the family moved to Bohemia . Kaznelson studied medicine at the Karl Ferdinand University in Prague until 1917 . One of his teachers was Hermann Schloffer .

In 1919 Kaznelson became a Czechoslovak citizen. From 1926 he was a private lecturer for special pathology and therapy of internal diseases at the Karl Ferdinand University. The period between the world wars was the most scientifically productive period in Kaznelson's life. After the occupation of the so-called "remaining Czech Republic" by the German Reich , he fled to England via Switzerland and France in 1939/40 due to his Jewish origins . He lived and worked there until his return to Czechoslovakia after the war.

The Czechoslovak authorities, however, regarded him as a German because of his membership of the faculty of the German university in Prague and denied him recognition of his Czechoslovak citizenship . Kaznelson then returned to England in 1950 and applied for British citizenship. However, he only received a residence and work permit.

Kaznelson died in Germany in 1959.

He was married to Katerina Pazderova, the couple had no children.

Act

While still a medical student, Kaznelson suggested to his teacher Schloffer in 1916 that the spleen of a patient with thrombocytopenic purpura should be removed . This operation has long remained a standard treatment for thrombocytopenic purpura. It is still used today as an emergency measure in severe cases.

In 1922 Kaznelson was the first to describe erythroblastopenia , a form of anemia .

Other fields of work were blood coagulation , leukemia and iron deficiency anemia . Here he was the first to recognize the connection between hollow nails and iron deficiency anemia. Iron deficiency anemia, known today as Faber syndrome, as a result of reduced iron absorption in achylie and accelerated gastrointestinal passage, was sometimes also called Kaznelson's syndrome .

After his escape from Prague, Kaznelson's scientific work came to a standstill. In the literature there is only one request to speak from 1942.
