Insulin secretion in women with polycystic ovary syndrome
Grimmichová, Tereza ; Haluzík, Martin (advisor) ; Marešová, Dana (referee) ; Rešlová, Taťána (referee)
Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies occuring in 5-10% women in their fertile years. The incidence of impaired glucose tolerance and diabetes mellitus type 2 is significantly increased in PCOS. Hyperinsulinaemia and insulin resistance are present in a relevant number of PCOS women. In our projects we therefore concentrated on various aspects of insulin secretion in PCOS women. We used different approaches and calculations, which are complementary to each other and provide a more detailed insight into possible beta cell dysfunction. Aims of our studies were 1) examine how the beta cell function is influenced by the family history of DM 2, 2) examine the insulin pulsatile secretion, 3) examine the secretion of incretins and 4) examine the prevalence of glucose intolerance and its potential prediction in PCOS women. 1) Decreased insulin sensitivity was observed only in PCOS women with the positive family history of DM 2 in comparison to healthy controls. If these women have normal glucose tolerance, they compensate the decreased insulin sensititivity by the increased insulin secretion. 2) Lean PCOS women had similar insulin pulsatile secretion patterns with the exception of broader insulin peaks in comparison to healthy controls. Insulin sensitivity was not associated...

Possible use of doppler flowmetry in the detection of discordant growth of twins
Musilová, Ivana ; Rešlová, Taťána (advisor) ; Měchurová, Alena (referee) ; Ľubušký, Marek (referee)
Objective: To evaluate the efficiency of selected doppler parameters as a test for the prediction of twin growth discordancy (GD) and to compare it with the efficiency of routinely used ultrasound biometrical parameters. Design: Prospective clinical study. Methods: Set was formed by 63 twin pregancies. Intertwin differences in Doppler parameters (umbilical artery - AU, middle cerebral artery - MCA, cerebroplacental ratio - CPR) and biometrical parameters (biparietal diameter - BPD, abdominal circumference - AC, femur length - FL, estimated fetal weight - EFW) were studied. Simultaneously, uterine arteries impedance was assessed. GD was identified by the birth weight difference from 20%. The efficiency of intertwin differences in studied parameters were evaluated using ROC analysis. Results: Biometrical measurements performed within three weeks antepartum were in prediction of GD more accurate than doppler parameters (AUC for EFW 0.99; for AU 0.56; for CPR 0.71). Three to six weeks antepartum, the efficiency of biometrical and doppler parameters was comparable (AUC for EFW 0.79; for AU 0.81; for CPR 0.81). In interval more than six weeks antepartum, biometrical parameters were not effective, DG was predictable only using CPR (AUC for EFW 0.62; for AU 0.56; for CPR 0.77). No significant differences...

Ultrazvukem navigovaná biopsie silnou jehlou je bezpečná, rychlá a spolehlivá metoda k histologické verifikaci pokročilého nebo recidivujícího abdominopelvického nádoru. Výkon lze provést ambulantně, bez nutnosti celkové anestézie, při minimálním dyskomfortu pro pacienta ve srovnání s laparoskopií nebo laparotomií. Riziko komplikací je nízké a hlavní výhodou je získání adekvátního histologického vzorku s možností následného imunohistochemického vyšetření, které je nezbytným předpokladem pro volbu optimální onkologické léčby.
