Transabdominal punction of follicular fluid in IVF cyclus in a patient after ovarian transposition.

OBJECTIVE: Description of punction of follicular fluid in a patient after ovarian transposition. DESIGN: Case report. SETTING: Department of Obstetrics and Gynaecology, 1st Faculty of Medicine, Charles University and the General Faculty Hospital, Prague. CASE REPORT: We present a case of IVF treatment in a patient with ovarian transposition undergoing punction of follicular fluid and difficulties during this procedure acording to transabdominal route. CONCLUSION: Transabdominal punction od follicular fluid is possible, but with technical difficulities and smaller amount of obtained oocytes. We recomend to aplicate IVF procedures prior to surgical solution.

Clinical impact of PAI 1 4G/5G gene polymorphism in colorectal carcinoma patients.

Plasminogen activator ihnibitor (PAI 1) belongs to the plasminogen activator system, which is part of the metastatic cascade and significantly contributes to invasive growth and angiogenesis of malignant tumors. Its plasma level is normally low but 4G/4G homozygotes have higher concentrations of PAI 1. This genotype may be associated with worse prognosis and proximal location of colorectal cancer than 5G/5G homozygotes. In our prospective evaluation we examined plasma level PAI 1 (using photometric microplate method ELISA) pre-surgery and, subsequently, 6-8 weeks later, from 80 patients. For the PAI 1 rs1799889 -675 4G/5G polymorphism test the PCR amplification was used.Analysis of collected data was confirmed that significantly higher plasma levels of PAI 1 were found in patients before starting therapy, which decreased (p=0.004) after initiation of treatment. Patients with higher plasma level PAI 1 before (p=0.013) and after therapy (p=0.004) had significantly shorter survival. We found no relationship between polymorphisms of PAI 1 (-675 4G/5G) in relation to stage, survival or tumor location. PAI 1 is useful as a negative marker of prognosis and could be advantageous when planning adjuvant treatment of patients with colorectal carcinoma. Although opinions on the importance of polymorphisms of PAI 1 in relation to the prognosis are not uniform, it does seem that their role in the prognosis of patients with colorectal cancer is not essential.
