    Notes: Abstract Vulvovestibular fistulas usually have a good prognosis. Most pediatric surgeons use operations such as cutback, fistula transposition without colostomy, and lately, posterior sagittal anorectoplasty with colostomy. Since 1978, the authors have been involved in the surgical treatment of 18 patients with vestibular fistulas without colostomy using a modified Santulli technique. Our results are satisfactory. We discuss voluntary bowel movements, soiling, constipation, and cosmetic effects. Comparisons are made between the three techniques with a discussion of advantages and disadvantages. We personally prefer anal transposition without colostomy.

    Notes: Abstract Urethral prolapse occurring in patients with vulvovestibular fistula has not been reported to date. We present two such cases in 7.5- and 9.2-year-old girls, respectively, in whom urethral prolapse developed after anal transposition. The relationship between the two entities is still unclear. It also remains controversial whether urethral prolapse is the result of a local anomaly, anal transposition, or some other cause. Constipation and increased intra-abdominal pressure seem to have been the most likely etiological factors in our patients.

    Description / Table of Contents: Zusammenfassung In den synaptischen Bläschen der Nervenendigungen der Epiphyse von Ratten, welche 2 und 4 Tage einer Temperatur von −6° bis −8°C ausgesetzt worden waren, hat man eine signifikante Vermehrung des Zinkjodid-Osmiumtetroxyd (ZIO) reaktiven Materials festgestellt. Der durchschnittliche Durchmesser der ZIO-positiven synaptischen Vesiculae betrug bei den Kontrollratten 234 Å und bei den Ratten, welche 2 und 4 Tage unter der Kälte gelebt hatten, 380 Å, bzw. 379 Å. Die ZIO-Reaktion war bei den Kontrollratten in 49,3% der synaptischen Vesiculae positiv, nach zweitägiger Kälteeinwirkung waren 58,7% und nach viertägiger Kälteeinwirkung 72,1% der synaptischen Vesiculae ZIO-positiv. Auf Grund der vorliegenden Arbeit war es jedoch nicht möglich zu entscheiden, ob die Vermehrung des ZIO-reaktiven Materials mit einer gleichzeitigen Zunahme der biogenen Amine verbunden ist.
    Notes: Summary In the synaptic vesicles of pineal nerve endings of Wistar rats exposed for 2 and 4 days to a temperature of −6° to −8° C, a significant increase of the zinc iodide-osmium tetroxide (ZIO) reactive material was observed. The mean diameter of ZIO reactive synaptic vesicles of control rats was 234 Å; in rats exposed to cold for 2 and 4 days it was 380 Å, respectively 379 Å. In control rats the ZIO reaction was positive in 49,3% of the synaptic vesicles. The reactivity increased to 58,7% in rats exposed to cold for 2 days, and to 72,1% in rats exposed to cold for 4 days. However, the results of the present study do not permit to conclude if an increase of ZIO reactive material is accompanied by a simultaneuos increase of biogenic amines.
