    Description / Table of Contents: Zusammenfassung. Bei einer 57 jährigen dialysepflichtigen Patientin mit generalisierter Arteriosklerose trat ein 3-Etagen-Verschluß der Mesenterialarterien mit schnell progredienter Symptomatik auf. Die arteriographische Diagnostik zeigte, daß der gesamte Magen-Darm-Trakt über eine Collaterale aus der A. rectalis superior über die Dick- und Dünndarmarkaden und weiter über die Bühler-Anastomose (pancreaticoduodenale Arkaden) versorgt wurde. Die Revascularisierung erfolgte über die A. mesenterica superior mit Hilfe eines Gore-Tex®-Interponates. Der postoperative Verlauf war durch die schweren internistischen Begleiterkrankungen der Patientin verlängert; chirurgische Komplikationen traten nicht auf, die Symptomatik der Angina abdominalis besserte sich innerhalb weniger Tage. Der Fallbericht zeigt, daß auch bei Patienten mit einem erhöhten Risiko eine Revascularisierung der Mesenterialgefäße durchgeführt werden kann. Eine Einzelgefäßrevascularisation scheint bei der bestehenden Collateralisierung ausreichend.
    Notes: Summary. A 57-year-old patient with general arteriosclerosis and end-stage renal failure was found to be suffering from occlusion of the mesenteric arteries. The symptoms were rapidly progressive. The aortogram showed that nutrition of the whole intestine took place via a collateral vessel that originated at both internal iliac arteries. Revascularization of the superior mesenteric artery with interposition of Gore-Tex prosthesis and transposition to the aorta were performed. The postoperative course was uncomplicated, but prolonged due to the accompanying diseases. In conclusion, single-vessel revascularization for chronic intestinal ischemia is a safe and sufficient procedure. Interpositioning of a graft and transposition to the aorta have the advantages of infrarenal access with an antegrade blood flow and no kinking of the prosthesis.

    Notes: Abstract Objective: We investigated whether a treatment according to a clinical algorithm could improve the low survival rates in acute respiratory distress syndrome (ARDS). Design: Uncontrolled prospective trial. Setting: One university hospital intensive care department. Patients and participants: 122 patients with ARDS, consecutively admitted to the ICU. Interventions: ARDS was treated according to a criteria-defined clinical algorithm. The algorithm distinguished two main treatment groups: The AT-sine-ECMO (advanced treatment without extracorporeal membrane oxygenation) group (n = 73) received a treatment consisting of a set of advanced non-invasive treatment options, the ECMO treatment group (n = 49) received additional extracorporeal membrane oxygenation (ECMO) using heparin-coated systems. Measurements and results: The groups differed in both APACHE II (16 ± 5 vs 18 ± 5 points, p = 0.01) and Murray scores (3.2 ± 0.3 vs 3.4 ± 0.3 points, p = 0.0001), the duration of mechanical ventilation prior to admission (10 ± 9 vs 13 ± 9 days, p = 0.0151), and length of ICU stay in Berlin (31 ± 17 vs 50 ± 36 days, p = 0.0016). Initial PaO2/FIO2 was 86 ± 27 mm Hg in AT-sine-ECMO patients that improved to 165 ± 107 mm Hg on ICU day 1, while ECMO patients showed an initial PaO2/FIO2 of 67 ± 28 mm Hg and improvement to 160 ± 102 mm Hg was not reached until ICU day 13. Q˙S/Q˙T was significantly higher in the ECMO-treated group and exceeded 50 % during the first 14 ICU days. The overall survival rate in our 122 ARDS patients was 75 %. Survival rates were 89 % in the AT-sine ECMO group and 55 % in the ECMO treatment group (p = 0.0000). Conclusions: We conclude that patients with ARDS can be successfully treated with the clinical algorithm and high survival rates can be achieved.

    Notes: Summary A test procedure for PSTVd is described based on immobilisation of plant sap on filter paper, by dotting or tissue printing followed by RT-PCR. Tests were carried out using primarily and secondarily infected potato plants, primarily infected in vitro plants, and potato tubers. Print PCR was shown to be suitable for testing large samples of potato plants whereas dot PCR is recommended for in vitro plantlets and tuber tissue. Bulking one infected plant to 4 or 9 healthy plants gave reliable results with secondarily infected potato plants, but sometimes the test failed to detect PSTVd in primarily infected in vitro plants. Dotted and printed paper squares could be stored at 4°C for at least 2 weeks in Triton X-100 solution or under dry conditions. Storing at room temperature can lead to unreliable results.
