Kříž, Jaroslav Thierry ; Košťál, Milan (advisor) ; Kudela, Milan (referee) ; Bouda, Jiří (referee)
Summary: Impact of Chlamydia trachomatis infection on chronic pelvic pain. The aim of the study was to determine whether women with chronic pelvic pain and Chlamydia infection differ from women with chronic pelvic pain without Chlamydia infection in respect of findings on laparoscopy and sexual behaviour. In a study conducted from April 2006 to December 2009, we monitored a group of 129 female patients suffering from chronic pelvic pain of more than 6 months duration. All monitored patients underwent laparoscopy, and during the procedure, swabs were taken from their Fallopian tubes and cervix, which were immunofluorescensed for the presence of Chlamydia trachomatis antigen. The patients were divided into two groups (Chlamydia positive and Chlamydia negative) according to the presence of Chlamydia antigen. The patients completed questionnaires covering the age at first sexual intercourse, number of lifetime and current sexual partners, frequency of sexual intercourse and the method of contraception. The differences in findings on laparoscopy and questionnaire results of women with positive and negative proof of Chlamydia infection were studied. Fisher's exact test was used for data description and group differences analysis. We observed that 30,2% (n=39) of a cohort of 129 women with chronic pelvic pain were...

Topographical anatomy of the retroperitoneum and its blood vessels and lymphatics
Turyna, Radovan ; Kachlík, David (advisor) ; Bouda, Jiří (referee) ; Naňka, Ondřej (referee)
The purpose of this study was to describe the distribution and structure
of ventral tributaries leading into the inferior vena cava where right-sided paraaortic lymphadenectomy is performed. The study examined
21 retroperitoneal specimens by graphic reconstruction, statistical evaluation, and histological examination of ventral tributaries (VTs). Seventy VTs were identified. The average number per specimen was 3.33. There were 20, 40, and 40% of VTs found in Levels I, II, and III, respectively. During the preparation, we observed an unusual arrangement of the IVC wall, into which VTs were led through a preformed sleeve-like channel and anchored near the lumen. This finding is a key mechanism that explains the ease with which VTs are extracted during surgery. Due to the lack of uniformity concerning the moniker for VTs in the literature, and due to the typical anatomical position and distribution of VTs within retroperitoneum, we propose that these veins should be called venae retroperitoneales anteriores. The second aim of the study was to gain a thorough knowledge of the topography and distribution of until now officially unnamed minute direct branches from abdominal aorta, stemming from its ventral and lateral aspects, supplying surrounding tissue, and to comprise it to the existing studies. Due to the...

Biological behavior of ovarian carcinoma and its relation to therapy
Bartáková, Alena ; Bouda, Jiří (advisor) ; Špaček, Jiří (referee) ; Svoboda, Tomáš (referee)
Structured abstract Hypothesis Cancer stem cells (CSCs) are subpopulations of cells which could contribute to tumor growth, metastasis formation and chemoresistance. CSCs can be detected by surface markers assessed by immunohistochemistry methods. A typical surface marker for CSCs is CD44 (standard form). We assumed, that CD44(s) could serve as a prognostic factor and marker of chemoresistance in patients with epithelial ovarian cancer. The aim of study 1. To recruit group of patients with histologically verified epithelial ovarian carcinoma. 2. To evaluate prognostic significance of known prognostic factors in our series of patients. 3. To assess the expression of CD44 in specimens of primary tumors and specimens of implantation metastasis using immnunohistochemistry and analyze their correlation. 4. To evaluate the expression of CD44 in relation to known prognostic factors. To analyze the significance of CD44 expression evaluation for overall survival, disease-free interval and chemoresistance. To find CD44 positivity cut-off by using statistical methods Materials and Methods A retrospective study was performed on 87 patients with histologically verified EOC. All patients were tested for primary tumor specimens, 48 of them were tested with regard to both specimens of primary tumor and implantation...

The prevalence of anal HPV infection in women with high grade cervical intraepithelial neoplasia and its relation to sexual behavior
Sehnal, Borek ; Sláma, Jiří (advisor) ; Bouda, Jiří (referee) ; Prausová, Jana (referee)
Background: More than 90 % of anal cancers are caused by high-risk human papillomavirus (HR HPV) infection and a history of cervical intraepithelial neoplasia (CIN) and cervical cancer is established as possible risk factor. The aim of this study was to demonstrate relationship between anal and cervical HPV infection in women with different grades of CIN and microinvasive cervical cancer and to determinate potential risk factors for concurrent cervical-anal HPV infection. Methods: A total of 272 women were enrolled in the study. The study group included 172 women who underwent conization for high-grade CIN or microinvasive cervical cancer. The control group consisted of 100 women with non-neoplastic gynecologic diseases or biopsy- confirmed CIN 1. All participants completed a questionnaire detailing their medical history and sexual risk factors and were subjected to anal and cervical HPV genotyping using Lynear array test (Roche). Results: Cervical, anal, and concurrent cervical-anal HPV infections were detected in 82.6 %, 48.3 % and 42.4 % of women in the study group, and in 28.0 %, 26.0 % and 8.0 % of women in the control group, respectively. The prevalence of the HR HPV genotypes was higher in the study group and significantly increased with the severity of cervical lesion. Concurrent infections...

DNA methylation changes in ovarian cancer patients
Chmelařová, Marcela ; Palička, Vladimír (advisor) ; Vávrová, Jiřina (referee) ; Bouda, Jiří (referee)
DNA methylation changes in ovarian cancer patients. In our work we studied DNA methylation changes in ovarian cancer. Due to the aggressive nature of this disease, it is very important to obtain detailed mapping of molecular parameters including epigenetics. These parameters could potentially be used in the diagnostics and treatment of ovarian cancer. To begin with, we focused on establishing and optimizing techniques which are suitable for methylation analysis of DNA isolated from paraffin blocks. The next step was to analyze selected CpG loci primarily of tumor suppressor genes. Formalin-fixed, paraffin-embedded tissue samples from both ovarian adenocarcinomas and normal ovarian tissue were obtained from 109 women (69 patients with ovarian cancer, 40 patients with normal ovarium) treated at the Department of Obstetrics and Gynecology, University Hospital Hradec Kralove. The samples of normal ovary were obtained from patients surgically treated for non-malignant diagnosis. DNA was extracted using a Qiagen DNA extraction kit. We established and optimized two techniques - MSP (Methylation specific PCR) and MS-MLPA (Methylation Specific Multiplex Ligation-dependent Probe Amplification). We discovered that for methylation analysis of poor quality DNA isolated from paraffin blocks MS-MLPA is more...
