Occurrence of woman cervical cancer in South Bohemian Region.
NĚMCOVÁ, Eva
Cervical cancer represents an enormous health, psychological and social stress for every woman. The most important risk factor in the development of cervical carcinoma, which the second most common malignant cancer in women, is infection with a high-risk strain of human papillomavirus - a very frequent sexually transmitted disease. More than 100 types of HPV are acknowledged to exist, with HPV 16 and 18 being classified as high-risk types in particular. Worldwide, 500,000 new cases of cervical cancer are diagnosed every year. In the Czech Republic, there are 1,000 new cases of cervical cancer each year, out of which up to 400 women die. It is estimated that there will be up to 1,000,000 new cases of cervical cancer by 2050 unless the prevention is improved. Every woman is at risk of developing cervical cancer. HPV is sexually transmitted, however not only by sexual intercourse but also by skin-to-skin-contact with infected areas. Other risk factors in the development of the disease are: first sexual intercourse at early age, the number of sexual partners, smoking, other sexually transmitted diseases and a long term use of hormonal contraception. Use of condoms, which protects against sexually transmitted diseases, reduces the transmission of HPV by up to 70%. Having regular gynaecological check-ups with Pap smears is crucial for cervical cancer screening, as the screening suggests the presence of cytological abnormalities and pre-cancer. However, it cannot detect all types of premalignant changes and early stages of the carcinoma. Two vaccines have recently been developed, effective against the most frequent oncogenic strains of HPV (16 and 18), which currently cause about 70% of cervical cancer cases. Active immunisation against human papillomavirus is the first vaccination against carcinoma. Together with screening, it represents the best prevention method against cervical carcinoma. Based on the research of technical literature, the first part of the dissertation gives an overall view of the issue of cervical carcinoma. The second part of the dissertation deals with the research, eliciting the knowledge and attitude of women from Southern Bohemian towns in the field of cervical carcinoma prevention in the period of December 2008 - March 2009 and comparing it to technical literature.

Incidence of Blood-Born and Sexually Transmitted Infectious Diseases with Focus on HBV and HCV in the Central Bohemia Region.
VELEKOVÁ, Petra
Viral hepatitides B and C are among the most widespread and at the same time most serious blood-born and sexually transmitted infectious diseases. The World Health Organisation considers the incidence of both infections to be an epidemic and, according to its estimates, there are 2 billion of people infected by hepatitis B virus and over 170 million of people infected by hepatitis C virus worldwide. Viral hepatitides B and C are diseases infecting the liver frequently becoming chronic and presenting a major factor in hepatocellular carcinoma development. Acute hepatitis C allegedly develops into chronic condition in approximately 85 % of CASE, and around one third of chronic hepatitis C patiens develop cirrhosis and many of them a liver carcinoma. There is a direct correlation between the incidence of acute hepatitis B developing into a chronic condition and possibly leading to cirrhosis or a hepatocellular carcinoma and the patientś age, it is indicated at 90 {--} 95 % in neonates, at 25 {--} 50 % in 1 to 5-year-olds, at 5 {--} 10 % in older children and adults. These diseases also have considerable socioeconomic impacts. Vaccination has been the most effective preventive measure agains viral hepatitis B, so far, no effective vaccine has been found for hepatitis C virus. The fundamental precautions against both types of viral hepatis consist in non-specific prevention related to the means of transmission of infection, namely avoiding contact with blood and other body fluids of any infected person. Both hepatitis B and C are most frequently trasmitted parenterally, by means of sexual intercourse, vertical transmission is less common. Before the introduction of screening tests for blood donors, viral hepatitides B and C were most frequently transferred via blood transfusion. At present, intravenous administration of illicit drugs presents a major risk factor due to sharing needles, syringes and other instruments among users. The theoretical part of the thesis summarizes present day knowledge on viral hepatitides B and C. The practical part focuses on the incidence and means of transmission of viral hepatitis B and viral hepatitis C in the Central Bohemia Region within a 10-year period. I also aimed to examine viral hepatitides B and C transmission risks awareness, and safe-sex rules observation among a selected group of the Central Bohemia population.
