Plain film radiography often underestimates the extent of injury in children with epiphyseal fracture. Especially Salter-Harris V fractures (crush fracture of the epiphyseal plate) are often primarily not detected. MRI of the ankle was performed in 10 children aged 9-17 (mean 14) years with suspected epiphyseal injury using 1.0-T Magnetom Expert. The fractures were classified according to the Salter-Harris-Rang-Odgen classification and compared with the results of plain radiography. In one case MRI could exclude epiphyseal injury; in four cases the MRI findings changed the therapeutic management. The visualisation of the fracture in three orthogonal planes and the possibility of detection of cartilage and ligamentous injury in MR imaging makes this method superior to conventional radiography and CT. With respect to radiation exposure MRI instead of CT should be used for the diagnosis of epiphyseal injuries in children.

During episodes of trauma carnitine-free total parenteral nutrition (TPN) may result in a reduction of the total body carnitine pool, leading to a diminished rate of fat oxidation. Sixteen patients undergoing esophagectomy were equally and randomly divided and received isonitrogenous (0.2 gN/kg.day) and isocaloric (35 kcal/kg.day TPN over 11 days without and with L-carnitine supplementation (12 mg/kg.day). Compared with healthy controls, the total body carnitine pool was significantly reduced in both groups prior to the operation. Without supplementation carnitine concentrations were maintained, while daily provision of carnitine resulted in an elevation of total carnitine mainly due to an increase of the free fraction. Without supplementation the cumulative urinary carnitine losses were 11.5 +/- 6.3 mmol corresponding to 15.5% +/- 8.5% of the estimated total body carnitine pool. Patients receiving carnitine revealed a positive carnitine balance in the immediate postoperative phase, 11.1% +/- 19.0% of the infused carnitine being retained. After 11 days of treatment comparable values for respiratory quotient, plasma triglycerides, free fatty acids, ketone bodies, and cumulative nitrogen balance were observed. It is concluded that in the patient population studied here carnitine supplementation during postoperative TPN did not improve fat oxidation or nitrogen balance.

Die Bestrebungen für eine Regierungsreform in der Schweiz lassen sich weit zurückverfolgen, sie führten aber zu keinen weitreichenden Ände-rungen betreffend das Regierungsorgan. Hauptsächliche Folgen waren Verwaltungsreformen. Schrittweise oder inkrementalistische Änderungen sind feststellbar. Sie betreffen die sogenannte Organisationsgewalt, die Bundeskanzlei, die Führungsstäbe, vor allem aber die Staatssekretärinnen und Staatssekre-täre. Die Leitplanken und die Zusatzbotschaft aus dem Jahr 2010 des Bun-desrates für eine Regierungsreform richten sich nach den Ergebnissen des Beitrages nach inkrementalistischen Entwicklungen aus. Mit der Verlängerung der Amtsdauer der Bundespräsidentin oder des Bundes-präsidenten könnte zudem ein neuer Entwicklungspfad begründet wer-den. Dem aktuellen Reformanstoss werden auf Grund der verwendeten Erklärungsansätze erhöhte Chancen zugemessen. Les efforts pour une réforme du gouvernement en Suisse remontent loin, mais ils n'ont pas abouti à des modifications de longue portée concernant l'organe gouvernemental. Les résultats principaux étaient des réformes de l'administration. Des modifications graduelles ou incrémentales sont détectables. Elles concernent le pouvoir d'organisation, la Chancellerie fédérale, les états-majors, mais surtout les secrétaires d'État. Les axes principaux et le message additionnel pour une réforme du gouvernement sont orientés vers les développements incrémentales constatés selon les recherches effectuées. L'allongement de la durée de fonction du président de la Confédération pourrait en plus constituer un nouveau chemin du développement. L'impulsion actuelle pour une réforme a des chances élevées d'aboutir selon les essais d'explication.

Eosinophilic esophagitis is characterized by symptoms of esophageal dysfunction and eosinophil-predominant esophageal inflammation. Eosinophilic inflammation in other parts of the gastrointestinal tract is absent and several differential diagnoses for esophageal eosinophilia have to be excluded before diagnosing eosinophilic esophagitis. Most patients are male and have concomitant atopic disorders. Therapeutic options are based on drugs, diet and dilation.
