    Notes: Abstract The value of automated DNA cytometry for differentiation of testis cancer was evaluated in 54 seminomas, 13 HCG-positive seminomas, and 48 embryonal carcinomas. Slices of paraffin embedded tissue were enzymatically digested and stained with Feulgen SITS after fixation on glass slides. Automated DNA cytometry was performed with a Modular Image Analysis Computer (MIAC). DNA histogram phenotpye and computed DNA indices were correlated with the different tumor types. The ratio of hypertriploid to hypotriploid increased from HCG-positive seminoma over embryonal carcinoma to seminoma. The following mathematical DNA indices were found to correlate with tumor type: mean ploidy, 2c deviation index, 5c exceeding rate, variation coefficient of the GO/1 fraction and DNA nucleus diameter correlation.

    Notes: Abstract The formation of a bowel reservoir of large capacity at low pressure by using small and large bowel (ileocaecal segment) has proved reliable for achieving continent urinary diversion (n=80), for bladder augmentation (n=42) as well as for total bladder replacement (n=24). Encouraged by the results we obtained in our adult patients, we have used this technique during the last 3.5 years in 29 children. Indications for urinary diversions in children have been: neurogenic bladder with diplegia (n=8), bladder exstrophy (n=2), traumatic loss of the bladder (n=1), urogenital sinus (n=1) and rhabdomyosarcoma of the prostate or bladder (n=2). Bladder augmentation was indicated in 6 children with iatrogenic bladder loss, in 5 children with neurogenic bladder without diplegia and in 4 boys with incontinent epispadias or exstrophy. In children with bladder exstrophy or incontinent epispadias, continence was achieved using a modified Young-Dees technique with formation of a long intra-abdominal muscular tube made out of the bladder plate or the low-capacity bladder. The capacity of the urinary reservoir was guaranteed by bladder augmentation or bladder replacement with an ileocaecal pouch. During a mean follow-up period of 26 months (bladder augmentation) and 21 months (continent diversion) there was only one postoperative complication (intussusception ileus) which required operative revision. Two children had to undergo reoperation because of nipple problems. Follow-up, with monitoring of biochemical and metabolic parameters, is necessary to show whether this technique will provide a long-term successful solution for these problems.
