[DNA analysis in gestational trophoblastic disease].

OBJECTIVE: DNA analysis of different forms of gestational trophoblastic disease. DESIGN: Retrospective clinical study. SETTING: Slovak Center of Trophoblastic Disease, Bratislava, Slovak Republic. METHODS: In the period of September 1993 to April 2003, eighty-nine cases of gestational trophoblastic disease were analysed. There were 22 cases of partial hydatidiform moles, 58 cases of complete hydatidiform mole, 5 cases of invasive mole and 4 cases of gestational choriocarcinomas. Southern hybridization and polymerase chain reaction were used for DNA analysis. RESULTS: From 22 analyzed cases of partial hydatidiform moles 19 (86.4%) were triploid and 3 (13.6%) diploid ones. There were 58 cases of complete hydatidiform mole and out of them 29 (50%) were homozygous, 28 (48.3%) heterozygous, and in one case (1.7%) both paternal and maternal genome was detected. In 8 cases of heterozygous and in one case of homozygous complete hydatidiform mole occurred a malignant transformation to gestational choriocarcinoma. CONCLUSIONS: Molecular analysis can determine the nuclear DNA origin of complete hydatidiform mole and allow us to define the patients with higher risk of malignant transformation usually to gestational choriocarcinoma.

Management of intracavitary left atrium tumors during pregnancy - two case reports.

OBJECTIVE: Authors documented an individual management of intracavitary left atrium tumors diagnosed during pregnancy. SUBJECT: Two case reports were presented. Brain embolisation was supposed in the case one of intracavitary left atrium tumor. An urgent cardiosurgery at 24 weeks' gestation was performed on the cardiopulmonary bypass. In case two (multiple pregnancy - twins) cardiac tumor in left atrium was detected in third trimester of pregnancy. The mother was without any serious cardiac and systemic complications during the last trimester. Surgical approach was different - removal of tumor after delivery. CONCLUSION: The surgical approach should be determined by clinical behavior of left atrial cardiac tumors.

[Fertility after chemotherapy of gestational trophoblastic disease].

OBJECTIVE: To evaluate subsequent pregnancy experience in patients following chemotherapy for malignant form of gestational trophoblastic disease. DESIGN: Retrospective clinical study. SETTING: Slovak Center of Trophoblastic Disease, Bratislava, Slovak Republic. METHODS: There were evaluated subsequent pregnancy experiences in 38 patients after chemotherapy for malignant form of gestational trophoblastic disease registered in Slovak center of gestational trophoblastic disease. Histological and cytogenetical analysis of all placentas after deliveries and material from curettage specimens after miscarriages, abortions and ectopic pregnancies were performed. RESULTS: 11 women conceived following successful chemotherapy of gestational trophoblastic disease became pregnant a total 19 times. Out of them there were 9 full-term deliveries, 2 spontaneous abortion, 1 ended in ectopic pregnancy and 7 pregnancies were terminated in therapeutic abortion. Cytogenetical analysis was successful in 7 to 10 reproductive losses with normal karyotype in all analysed cases. CONCLUSION: Patients after successful chemotherapy of gestational trophoblastic disease have a normal reproductive outcome.

[Laparoscopic findings in women with chronic pelvic pain].

Chronic pelvic pain afflicts 5-10% of women. The diagnosis of its cause is predominantly assessed by means of laparoscopy which in 60-70% reveals various organic causes of pain. The retrospective study analyses the results of 43 laparoscopic examinations indicated due to chronic pelvic pain. The average age of patients was 29.97 years. Organic findings on internal genitals were found in 36 cases (83.7%). Endometriosis was diagnosed in 11 cases (25.6%). According to the criteria of American Fertility Society, 4 patients (36.4%) suffered from stage I, 6 patients (54.5%) suffered from stage II, and only one case (9.1%) was caused by stage III. Chronic inflammatory process was diagnosed in 12 cases (18.6%), adhesions without any other pathologic findings in 8 cases (18.6%), and ovarial cysts in 3 cases (7.0%). Varicose pelvic veins and uterine myoma occurred in one case (2.3%), respectively. In 7 cases, no pathological change was revealed. Laparoscopy in coincidence with chronic pelvic pain is a significant examination which helps to reveal the organic origin of disturbance. An early decision of applying this invasive examination contributes to fast assessment of the diagnose and commencement of treatment. (Tab. 2, Fig. 1, Ref. 32.)

[Papillomavirus infection of the uterine cervix in women using contraception].

OBJECTIVE: The authors analyze the prevalence of the anogenital form of HPV infection as one of the most frequent STD, in the female population using different types of contraception. METHODS: Using the method of DNA hybridization, the authors examined for HPV infection of the uterine cervix 245 users of contraception, incl. 127 women using hormonal contraception and 118 women with IUD. 112 women of this group were examined before they started to use contraception and one year after started to use it. The control group was formed by 143 using no contraception. RESULTS: The authors found a significantly higher incidence of HPV infection of the uterine cervix in the group of women using contraception (24.1%) than in the control group (15.4%). On analysis of the group of women using contraception, as compared with the control group, they found a significantly higher incidence of HPV in women with hormonal contraception (26.0%) while the higher prevalence of HPV (by 6.6%) in women with IUD as compared with the control group was not significant. However the differences in the incidence of HPV (4%) between the two groups of women taking hormonal preparations (26.0%) or having a IUD (22%) were not significant. On examination of women before the onset of contraception and after one year of its use the authors found that candidates of contraception had as compared with the control group an insignificantly (by 3.3%) higher prevalence of HPV already before the beginning of contraception. After one year of contraception it increased by another 3.6%. CONCLUSION: With regard to the higher incidence of HPV in women using contraception and with regard to the oncogenic effect of HPV the authors emphasize the importance of regular detailed gynaecological examinations of these women focused on early diagnosis of precancerous conditions of the uterine cervix.

Flow cytometry (FCM) analysis of endometrial hyperplasia and carcinoma.

In a series of 52 biopsy specimens (31 endometrial carcinomas, 10 atypical endometrial hyperplasias, and 11 cases of normal endometrium), DNA ploidy and S-phase cell fraction were estimated in paraffin-embedded material. DNA aneuploidy was detected in 2 of the 10 atypical endometrial hyperplasias and 7 of the 31 endometrial carcinomas. The majority of aneuploidy was found to be connected with the loss of tumor differentiation. No ploidy disturbances were found in normal endometrium. The S-phase cell fraction value of normal endometrium was significantly lower when compared with that of endometrial carcinoma. The broad variation in S-phase cell fraction values of the endometrial carcinomas and atypical endometrial hyperplasias was in contrast with the low variability of S-phase cell values of normal endometrium. Very low incidence of aneuploidy in the group of well differentiated endometrial carcinomas (Grade I) enables the suggestion that the presence of aneuploidy predicts a more aggressive disease and that the detection of an aneuploid stemline in atypical endometrial hyperplasia may already indicate the neoplastic transformation.
