[Conservative treatment of ectopic pregnancies and presentation of a complicated case of peritonitis due to methotrexate].

Due to the improvement of diagnostic procedures and the refinement of endoscopic methods, the treatment of ectopic pregnancy has more and more turned against salpingectomy and towards organ-preserving actions. Moreover, for some years a range of medical therapies has been offering an alternative to surgical intervention. In addition to presenting a review of conservative methods of treatment, we report on a patient with an angular pregnancy who was treated with methotrexate and developed a pronounced peritonitis.

[Possibilities and applications of pulse oximetry during labor].

Fetal pulsoxymetry gives the opportunity of constant registration of oxygen saturation in the fetus during delivery. Important changes of the utilized equipments are crucial for proper assessment of this parameter. Construction of the sensors is of special importance.

Telemedicine: application of telepathology-remote microscopy for intraoperative diagnoses on frozen sections.

Due to the time delay, intraoperative consultations result in an extension of operation times, leading to prolonged anesthesia and idle time during surgery. Using a remote controlled microscope for telepathology, transfer times between hospital and pathologist can be eliminated and pathological expertise obtained independently of the geographic location of the hospital. In cooperation with a community hospital located 100 km apart from the Institute of Pathology of the Justus Liebig University Giessen, telepathological intraoperative consultations have been performed since 1999.
