RESUMEN
Complete rectal prolapse or procidentia is an uncommon condition long recognized but of uncertain pathogenesis. We report two patients, seen a decade apart, both of whom developed complete rectal prolapse after ingestion of oral cathartics in preparation for diagnostic studies. To our knowledge, cathartic-induced complete rectal prolapse has not been reported previously in the current medical literature, despite the thousands of bowel preparations performed annually. These two cases address the implications of such an occurrence, and we discuss the pertinent management issues.

Mycotoxicosis due to ingestion of zearalenone was detected on 2 pig farms on the Atherton Tableland in northern Queensland. In one herd of 200 pigs, this resulted from feeding maize which had been stored with a high moisture content. In the other herd of 1400 pigs, it resulted from feeding sorghum grain which was rain affected before harvest. Concentrations of zearalenone in the feeds ranged up to 8 mg/kg. Most prepubertal gilts in the herds displayed enlarged teats and signs of oestrus such as having red, swollen vulvas. In several cases both rectal and vaginal prolapses occurred. On one of the farms, 25 pigs died as a direct result of prolapses. Autopsy of a 3-month-old gilt revealed apparently enlarged ovaries and uterine horns. Sows and boars seemed to be unaffected. Four gilts failed to conceive following mating during the period of zearalenone ingestion, but apart from this and the deaths from prolapses, production of the herds appeared to be unaffected.
