    Notes: Abstract  The contamination of cereals with field-growing Fusarium species can be a health hazard since Fusarium are known for their ability to produce mycotoxins like zearalenone (ZON) and deoxynivalenol (DON). For this study the formation of ZON was investigated under controlled growth conditions. Ergosterol, as an indicator of fungal growth, and ZON were analysed by HPLC with UV and fluorescence detection respectively. It is shown that ZON is synthesised in the late growth phase of the fungi, which is typical for secondary metabolites. Milling of contaminated wheat shows a reduced content of ZON in fractions of low ash content. Consequently the concentration of ZON in bran, which has a high ash content, was much higher.

    Notes: Abstract Sacral insufficiency fractures develop over a period of time and show time-dependent changes. We report on 15 CT examinations of 5 patients with early-stage insufficiency fractures of the sacrum. In 4 patients only irregular sclerosis without distinct fracture lines was present in 7 of 8 fractures. Of these 4 patients; 3 exhibited intraosseous gas inclusions in a ventral part of a lateral mass; 5 of 8 fractures disclosed a ventral cortical break. When distinct fracture lines had developed in 1 patient, intraosseous vacuum phenomenon had disappeared. Fracture lines evolve over weeks to months and show central bone absorption. The fractures can heal as demonstrated in 4 of 6 fractures in 3 patients, can persist over 1 year without significant changes or can progress to pseudoarthrosis with bone destruction similar to neuropathic joint disease. Intraosseous vacuum phenomena can persist to this stage. Intraosseous vacuum phenomenon is recognized as a potential finding in the early stage of sacral insufficiency fracture, which also is true for irregular sclerosis and ventral cortical disruption.

    Description / Table of Contents: Summary Purpose: Bronchial and arterial anastomotic stenoses are major complications after lung transplantation. Interventional techniques provide a definitive cure in certain cases. Material and methods: Three out of four patients had ischemia-related stenoses of the bronchial anastomoses postoperatively; one patient developed malacia of the bronchus main stem 1 year after transplantation. Four patients had stenoses of the arterial anastomoses, which resulted in hemodynamic instability and reduced perfusion of the graft. Results: Stent implantation in the bronchial anastomoses (n = 3) and in the main stem (n = 1) improved ventilation and oxygen saturation in all patients. The stents were incorporated by mucosal overgrowth, as demonstrated by endoscopy, as early as 6 weeks after implantation. Balloon dilatation (n = 3) and stent implantation (n = 1) were successfully performed in 4 patients with stenoses of the arterial anastomoses. The mean transstenotic pressure gradient of 9.5 mm Hg was reduced to 2.2 mm Hg after angioplasty. Lung perfusion shifted towards the grafts, as shown by 99mTc perfusion scans. Conclusion: The minimally invasive techniques of interventional radiology are very effective in the treatment of anastomotic complications after lung transplantation and may avoid surgery in certain cases.
    Notes: Zusammenfassung Komplikationen nach Lungentransplantation betreffen in erster Linie die Bronchusanastomose und die Pulmonalarterienanastomose. Sie sind ischämieinduziert oder auf chirurgisch-technische Probleme zurückzuführen. Bei 8 von 66 transplantierten Patienten traten postoperative Stenosen an der arteriellen Anastomose (n = 4) und an der Bronchusanastomose (n = 4) auf, die jeweils zu einem organ- bzw. lebensbedrohlichen Zustand der Patienten geführt hatten. Die interventionelle Behandlung war bei allen Patienten erfolgreich; 4 Patienten wurden bei Anastomosenstenose bzw. Malazie der Bronchusanastomose mit Metallstent versorgt, 4 Patienten mit Stenosierung an der Pulmonalarterienanastomose wurden einer Ballondilatation bzw. zusätzlicher Stentimplantation zugeführt. Die Indikation zur Behandlung und die Überprüfung des Dilatationsergebnisses wurde anhand der Stenosegradienten ermittelt, zur ausreichenden Erweiterung war eine Ballonkaliberstärke von 15 bis 20 mm erforderlich. Indikation zur Stentimplantation war eine elastische Instabilität bei einem Patienten. Der minimal-invasive Eingriff bei schwerkranken Patienten, die effiziente und komplikationslose Therapie und der erfolgreiche Langzeitverlauf sprechen dafür, bei Anastomosenproblemen nach Lungentransplantation interventionelle radiologische Verfahren primär einzusetzen.
