    Description / Table of Contents: Summary Introduction: Orthotopic liver transplantation (OLT) has become an accepted treatment for end-stage liver disease. However, postoperative complications result in significant patient morbidity and mortality. Early detection and treatment of these complications is therefore of utmost importance. Materials and methods: We retrospectively reviewed the postoperative complications of the patients who underwent OLT at our institution. Duplex Doppler sonography and cholangiography were the primary imaging modalities in postoperative evaluation of the transplanted liver. Other important techniques were CT, MRI, and angiography, which may contribute to a reliable diagnosis of vascular or biliary complications. Results: Second to primary organ dysfunction, vascular complications are the most frequent cause of graft loss. Thrombosis of the hepatic artery is the most common and most serious vascular complication, with a reported incidence from 4 to 42 %. Bile duct sludge, leaks and strictures are frequent complications after liver transplantation, which can contribute to graft dysfunction. Biliary tract complications usually occur within the first 3 months and require interventional radiological or surgical therapy. Since liver transplant recipients undergo immunosuppressive therapy, they are at increased risk of developing late post-transplant malignancies, which are best depicted by US, CT or MRI. However, radiological diagnosis of lymphoproliferative disorder has to be confirmed by liver biopsy. Conclusion: Cholangiography and Duplex sonography are routinely used in the postoperative evaluation of patients with OLT. CT, MRI, and angiography are problem-solving tools in equivocal cases.
    Notes: Zusammenfassung Einleitung: Die orthotope Lebertransplantation hat sich zu einer etablierten Therapie bei Lebererkrankungen im Endstadium entwickelt. Der frühe Nachweis und die prompte Therapie eventueller Komplikationen sind für das Überleben des Patienten und des Organs entscheidend. Material und Methode: Es wurden im eigenen Krankengut die postoperativen Komplikationen nach OLT retrospektiv ausgewertet. Die Duplexsonographie und die Cholangiographie erwiesen sich als die primären Untersuchungsmethoden der Wahl zum Nachweis vaskulärer oder biliärer Komplikationen. CT, MRI und die Angiographie waren in Problemfällen wertvolle additive bildgebende Verfahren zur Diagnosesicherung. Ergebnisse: Nach der primären Organdysfunktion sind die vaskulären Komplikationen als häufigste Ursache für den Verlust des Spendeorgans anzuführen. Die Thrombose der A. hepatica ist die häufigste vaskuläre Komplikationen mit einer Inzidenz von 4–42 %. Galleleaks, -sludge und -strikturen sind häufige Komplikationen, die letztlich zu einer Dysfunktion des transplantierten Organs führen können. Biliäre Komplikationen treten gehäuft in den ersten 3 Monaten auf und erfordern eine interventionelle oder chirurgische Therapie. Da Patienten nach OLT einer immunsuppressiven Therapie unterliegen, sind sie einem erhöhten Risiko einen lymphoproliferativen Tumor zu entwickeln ausgesetzt. Diese Posttransplant-Tumore können mit US, CT und MRI ausgezeichnet abgegrenzt werden, erfordern jedoch eine Sicherung der Diagnose durch eine Feinnadelpunktion. Schlußfolgerung: Die postoperative Verlaufskontrolle und der Nachweis von Komplikationen nach OLT ist eine Domäne von Cholangiographie und Duplexsonographie. In Problemfällen kommen CT, MRI und Angiographie zum Einsatz.

    Notes: Abstract We compared the results of a computerized attention test (TOVA) in 38 children with insulin dependent diabetes mellitus in relation to various spontaneously occurring blood glucose levels. Testing was performed at the following blood glucose levels: 〈3.3 mmol/l (hypoglycaemia), 3.3–8.3 mmol/l (normoglycaemia) and 〉8.3 mmol/l (hyperglycaemia) . The attention (sum of errors and response time) varied significantly with the blood glucose level (P=0.002). The highest number of errors of omission and the longest response time was observed during the test run with hypoglycaemia. Age, sex, age at manifestation of the disease, metabolic control and the results of the intelligence test had no significant influence on these results. We found that attention in children with diabetes was significantly reduced compared to TOVA norms especially during mild hypoglycaemia (P〈0.001). Irrespective of the blood glucose levels, reaction time and the variability of the reaction time differed significantly between TOVA norms and diabetic children (P〈0.01). Conclusion In children with diabetes mellitus a significant reduction in attention was found at mild hypoglycaemia but as well at low normal blood glucose levels. Attention deficits due to transient lowering of blood glucose may therefore occur in diabetic children even before they are aware of hypoglycaemic symptoms.

    Notes: Abstract A 15-year-old boy with achalasia of the oesophagus is described in whom growth retardation was the presenting and misleading symptom. Growth hormone (GH) and insulin-like growth factor-I secretion were decreased but GH therapy was unsuccessful. After pneumatic dilatation of the oesophageal sphincter catch up growth occurred.
