Prenatal three-dimensional sonographic findings associated with fetal defecation. Case Report.

Routine ultrasonography examination may miss fetal defecation and if seen it can be a source of misinterpretation which can lead to a wrong diagnose and management of pregnancy. We report two rare cases of fetal defecation in the second trimester and we describe 3D sonographic findings associated with this condition.

An SEM-EDX and Raman spectroscopic study of the fibrous arsenate mineral liskeardite and in comparison with other arsenates kaňkite, scorodite and yvonite.

The mineral liskeardite, an arsenate mineral with major cations of iron and aluminium, has been studied by a combination of scanning electron microscopy with energy dispersive spectroscopy and Raman spectroscopy. The mineral shows a fibrous nature. Semi-quantitative chemical analysis shows an Al and Fe arsenate phase with minor amounts of K, Cu, S and Si.

[Validity of the oncological cytodiagnostics and colposcopy examination versus biopsy in cervical carcinoma prevention].

The Aim Of The Study: The basic praebioptic methods detecting the precancerous lesions of the uterine cervix are oncologic cytology (PAP smears) and colposcopy. However in the Czech Republic the incidence of the invasive carcinomas during the last 10 years did not considerably decrease. Therefore the goal of our study is to estimate the validity of the prebioptic methods and compare the results of praebioptic methods (procedures) versus biopsy.

[Prevention of the invasion of malignant cells of gynecologic tumors during surgery].

Objective: In experiments performed on Vistar rats with Walker tumors, F. Luksch observed transfer of malignant cells during different manipulations into the blood circulation of the animals. During gynecologic surgery of a choriocarcinoma and of an ovarian carcinoma Luksch and Cernoch prooved trace of malignant cells within the blood circulation related to the manipulation of tumors during surgery.
