[Proctomucosectomy and colo-anal anastomosis in rectovaginal fistula following the use of suppositories containing ergotamine]. / Proktomucosektomie und coloanale Anastomose bei recto-vaginaler Fistel nach Anwendung ergotaminhaltiger Suppositorien.

We observed a rectovaginal fistula in 2 patients who had applied ergotamine suppositories against migraine headaches. The local effect of ergotamine on the rectum mucosa as well as the higher systemic concentration after rectal application seem to promote the development of a rectovaginal fistula. Different methods for the surgical fistula repair are discussed, depending on location and diameter of the fistula. In our patients we have carried out the abdomino-transanal resection of the rectum with sutured colo-anal anastomosis.

[Breeding strategies to increase fitness in poultry]. / Zuchtstrategien zur Fitnesssteigerung beim Geflügel.

The performance of the meat type hybrids of today is much higher than at the beginning of the century. Antagonistic relations between the polygenic performance traits and fitness are the reason why modern hybrids need optimal management conditions, their susceptibility to stress increased and their immunocompetence decreased. There will be discussed, how modern genetics is counteracting by using new selection techniques.
