Morphological and Immunohistochemical Analysis of Melanocytic Lesions
Důra, Miroslav ; Dundr, Pavel (advisor) ; Mandys, Václav (referee) ; Pock, Lumír (referee)
This doctoral thesis deals with morphological and immunohistochemical analysis of melanocytic lesions. Melanoma is the most dangerous malignant skin tumor with its potential occurrence outside the skin. Its early diagnosis is the basic aspect of a favorable disease prognosis. Distant metastases development occurring several years after the initial diagnosis is a typical feature of melanoma. Histopathological differential diagnostics of melanocytic lesions is extremely difficult because of the diversity of melanocytic lesions. Contemporary research is focused on the identification of new surrogate markers based on immunohistochemistry or molecular genetics, which would be enable to estimate the behavior of a certain lesion and clarify the gray zone of melanocytic lesions of uncertain biological behavior. The doctoral thesis is focused on the immunohistochemical analysis of GLUT-1 protein expression in 400 cases of benign and malignant melanocytic lesions. Significant expression of this marker was identified in the group of melanomas, it was not identified in melanocytic nevi. Expression of GLUT-1 corresponded to the worse prognosis of the disease. The doctoral thesis also deals with the issue of TILs. The analysis of TILs (tumor infiltrating lymphocytes) in 213 melanomas compared the prognostic...

Charles University First Medical Faculty Study programme: History of Medicine Summary of dissertation The Spanish Flu Pandemic 1918/19 with particular reference to the Bohemian Lands and Central European relations Dr. med. univ. Harald Salfellner Prague, 2017 Summary Towards the end of the First World War, in 1918 and 1919, humanity faced a previously unparalleled flu pandemic; within a few months, more people had been killed than in all the battles of the 1914-18 war put together. The precise number of victims is unknown but is today generally reckoned at between 20 and 50 million. The whole world was affected by the Spanish flu, with the exception of a few remote islands, and Europe, already bled to death by industrialised warfare, was particularly hard hit. In summer 1918, the pandemic reached Bohemia in an early, relatively benign wave. A few weeks later, thousands were struck down in Prague in a second and far more deadly phase of the illness. In October 1918, as the First Czechoslovakian Republic arose from the ashes of the multiethnic Austrian state, and the masses celebrated in the cities, thousands of feverish patients were coughing behind drawn curtains, and facing an uncertain fate. In the USA, the flu pandemic - the greatest health disaster of the 20th century - has been the subject of many...
