Accuracy of laparoscopic diagnosis of endometriosis.

Background And Objective: Laparoscopy is the standard method to visually identify endometriotic lesions under magnification within and outside the minor pelvis. The aim of this study was to analyze the accuracy of laparoscopic visualization in diagnosing the various endometriotic sites as confirmed histologically.

Method: Presumed endometriotic sites were observed in 164 patients operated on under the clinical suspicion of endometriosis.

Effect of water stress on cell division and cell-division-cycle 2-like cell-cycle kinase activity in wheat leaves.

In wheat (Triticum aestivum) seedlings subjected to a mild water stress (water potential of -0.3 MPa), the leaf-elongation rate was reduced by one-half and the mitotic activity of mesophyll cells was reduced to 42% of well-watered controls within 1 d. There was also a reduction in the length of the zone of mesophyll cell division to within 4 mm from the base compared with 8 mm in control leaves.

Critical evaluation of the specificity of MRI and TVUS for differentiation of malignant from benign adnexal lesions.

The aim of our work was to study the specificity of MRI in comparison with transvaginal US for differentiation of malignant from benign adnexal lesions. A total of 67 patients with clinically suspicious adnexal lesions were evaluated by MRI. Transaxial and coronal images were acquired using T1-weighted sequences before and following IV contrast and T2-weighted sequences.

[Acute and chronic fetofetal transfusion syndrome].

Background: In the fetofetal transfusion syndrome we can discriminate between a chronic form with severe difference in weight and an acute form with a difference in haemoglobin between the twins. The aim of the retrospective study was to investigate the influence of both forms regarding infant morbidity and mortality.

Patients: Of the 135 twins treated from 1.

[Preoperative differential diagnosis of cystic adnexal tumors: double-contrast MRT].

Purpose: Preoperative assessment of adnexal lesions as benign or malignant by MRI with gastrointestinal and intravenous contrast.

Methods: 46 patients with benign (n = 42) and malignant (n = 4) cystic adnexal tumours underwent MRI of the pelvis. Transaxial and coronal images were acquired using conventional T1- and T2-weighted SE-sequences after oral administration of superparamagnetic iron oxide particles (Ferristene).
