    Description / Table of Contents: Summary A 10-year old boy developed an arteriocavernosal fistula with a permanent penile erection (high-flow priapism) after a blunt perineal trauma. The diagnosis was established by Doppler ultrasound, blood gas analysis and angiography. A conservative treatment attempt with penile cooling and puncture of the cavernosal corpera with blood aspiration and etilefrine instillation failed to resolve the priapism. An embolization of both bulbocavernosal arteries was followed by an immediate detumescence. Normal functional erection was preserved. No recurrence was observed during a follow-up of 6 months.
    Notes: Zusammenfassung Bei einem 10jährigen Jungen kam es nach einem stumpfen perinealen Trauma zu einer Dauererektion durch eine arteriokavernöse Fistel (High-flow-Priapismus), die durch Doppler-Sonographie, Blutgasanalyse und Angiographie nachgewiesen wurde. Nach Versagen einer Behandlung mit Kühlung, Dekompression der Corpora cavernosa durch Punktion und Etilefrin-Instillationen wurde eine endovasale Verschlußbehandlung der die Fistel speisenden Aa. bulbourethrales mit Mikrocoils vorgenommen. Die Behandlung führte zu einer sofortigen Detumeszenz bei erhaltener Erektionsfähigkeit. Während einer Nachbeobachtungszeit von 6 Monaten trat kein Rezidiv des Priapismus auf.

    Notes: An automated system for preparative gas chromatography with capillary columns is described. The effluet from the capillary column is switched to the FID detector or to the traps by means of a Live-T switching device. The pneumatics is controlled by a microprocessor so that repetitive sampling can be performed over a period of days in order to enrich sufficient amount of material for NMR or other spectroscopic methods. The effluent containing the compounds is collected in glass tubes filled with column packing material (e.g. Chromosorb coated with 3% OV - 101, crosslinked). The trap temperatue can be adjusted from + 20°C to - 80°C, depending on the trapping material and volatility of trapped substances. The analysis of enriched substances or chromatographic fractions can be performed by thermal desorption of the same traps or by solven elution. The recovery of enriched substances is higher than 90%. High capacity and resolution for enrichment of trace components are obtained with the aid of a double column-double oven system. Examples of such applications are given.
