    Description / Table of Contents: Zusammenfassung Radiushalsfrakturen sind typische Verletzungen des Kindesalters. Bei geringer Dislokation des Radiusköpfchens ist die konservative Behandlung ausreichend. Bei Abkippwinkeln caber 30° wird die operative Aufrichtung empfohlen and Unterfütterung mit einem Spongiosakeil zur Fixation. Anschließend für 6 Wochen Oberarmgipsverband. In allen Fällen kam es zur vollen Funktionsrückkehr des Ellenbogengelenkes.
    Notes: Summary Fractures of the neck of the radius are typical childhood injuries. Minimal displacement requires only conservative treatment. In cases with more severe dislocation of the head of the radius (more than 30°) operative reduction followed by fixation with a wedge of spongiosa is recommended. Full function of the elbow joint is recovered.

    Notes: Abstract The ion currentI i to a Langmuir probe was measured in a Cs-plasma which was produced by contact ionization and for which the neutral densityn g is known and the plasma density is given by the Saha equation. Using the theory of Self and Shih the collision cross section σ(Cs+→Cs) was calculated from the measured ion currentI i .

    Description / Table of Contents: Abstract Background: The detection or ruling out of a patent foramen ovale (PFO) can be determined noninvasively by contrast echocardiography (CE). The transesophageal technique is superior to the transthoracic technique regarding sensitivity, whereas the specificity of both methods is equally high. This prospective study shows the rational use of transesophageal CE for the detection of a PFO, in patients without cardiovascular disorders. Methods: 165 patients (92 female, 73 male, age 48±18 years) with planned neuro-surgery in a sitting position, underwent CE to rule out a PFO. If the CE was positive, an alternative position was selected in order to avoid a paradoxical air embolism. Results: Initially, a transthoracic CE was performed in all patients resulting in 21 patients (13%) being positive and 39 patients (24%) being negative by sufficient image quality. A transesophageal CE was performed in 96 of the remaining 105 patients (63%). Here, further 25 patients showed a positive CE in the sense of a PFO. The combined use of transthoracic and transesophagel CE revealed a PFO in 46 of 165 patients (28%). Conclusion: The use of both, transthoracic and transesophageal CE is an efficient approach to the preoperative detection of a PFO in the sense of quality and economics. Depending upon the image quality, the use of a transesophageal examination could be avoided in one third of the cases.
    Notes: Zusammenfassung Die präoperative Kontrastechokardiographie (KE) wird zum Ausschluß eines offenen Foramen ovale (PFO) bei Patienten, die einer neurochirurgischen Intervention in sitzender Position unterzogen werden, eingesetzt. Die transösophageale (TEE) KE weist eine höhere Sensitivität in der Diagnostik eines PFO als die transthorakale (TTE) KE auf, während die Spezifität gleich hoch ist. Die Frage der vorliegenden prospektiven Studie war, in wie vielen Fällen die TEE-KE notwendig ist und von welchen Faktoren die Indikation beeinflußt wird. Patienten und Methodik: 165 Patienten (92 Frauen, 73 Männer, Alter 48±18 a) ohne kardiovaskuläre Erkrankungen, die einer neurochirurgischen Operation in sitzender Position unterzogen werden sollten, wurden einer präoperativen KE zum Ausschluß eines PFO zugeführt. Bei allen Patienten wurde zuerst eine TTE-KE durchgeführt. Bei einem positiven Ergebnis wurde auf eine TEE-KE verzichtet. Eine negative TTE-KE wurde lediglich akzeptiert, wenn eine ausreichende transthorakale Schallqualität vorhanden war. In allen anderen Fällen wurde eine TEE-KE angeschlossen. Ergebnisse: Die TTE-KE verlief bei 21 (13%) Patienten positiv und bei 39 (24%) negativ. Bei 105 (63%) mußte aufgrund der insuffizienten Schallqualität eine TEE-KE angeschlossen werden. Dabei wiesen weitere 25 Patienten ein PFO auf. Insgesamt wurden unter der kombinierten Anwendung der TTE-KE und TEE-KE bei 46 Patienten (28%) ein PFO diagnostiziert. In 30% der Fälle konnte auf eine TEE-KE verzichtet werden, wobei der limitierende Faktor der TTE-KE die mangelnde Schallqualität war. Schlußfolgerung: Bei der präoperativen KE zur Diagnostik eines PFO kann in Abhängigkeit von der transthorakalen Schallqualität in 30% auf eine TEE verzichtet werden. Durch einen rationalen Einsatz der TEE-KE können Kosten und unnötige Belastungen des Patienten vermieden werden.

    Description / Table of Contents: Zusammenfassung Die PHLA des Plasmas wurde bei 10 gesunden freiwilligen Versuchspersonen vor und während einer oralen Belastung mit 0,5 g Äthylalkohol/kg Körpergewicht als Initialdosis und 0,1 g Äthylalkohol/kg Körpergewicht und Stunde über 5 Stunden gemessen. Diese Äthanolbelastung führt zu einem Anstieg der Plasmatriglyceride auf etwa 170% des Ausgangswertes. Die PHLA des Plasmas wurde bestimmt vor, 15 Minuten, 1 und 5 Stunden nach Einnahme der Initialdosis. Sie änderte sich während der Alkoholbelastung gegenüber dem Ausgangswert wie gegenüber einer Kontrollserie mit Mineralwasser nicht signifikant. Dieser Befund wird verglichen mit früheren Untersuchungsergebnissen. Es wird die Schlußfolgerung gezogen, daß die akute äthanolinduzierte Hyperlipoproteinämie im gesunden Menschen vorwiegend durch eine Steigerung der Triglyceridsynthese in der Leber und Ausschleusung von VLDL und nicht durch eine verminderte Metabolisierung triglyceridreicher Lipoproteine bedingt zu sein scheint.
    Notes: Summary Post-heparin lipolytic-activity (PHLA) was studied in 10 healthy volunteers ingesting 0.5 g of ethanol/kg body weight initially and 0.1 g/kg body weight and hour over 5 hours. This dose led to enhancement in plasma triglycerides to about 170% of the pre-ethanol values. PHLA was determined before, 15 min, 1 and 5 hours after intake of the initial dose and showed no significant changes. These findings are compared with the results of earlier investigations. It is concluded that acute ethanol induced hyperlipoproteinemia in healthy man seems to be due mainly to enhanced hepatic synthesis of triglycerides and release of very low density lipoproteins and not to decreased catabolism of triglyceride rich lipoproteins.

    Notes: Summary An attempt was made to establish a decision algorithm for the treatment of idiopathic Parkinson's disease at various stages and in different subgroups such as akinetic-rigid or tremor dominance type. We suggest treating young patients with selegiline and a dopamine agonist. In the tremor dominance type we use either budipine or a dopamine agonist. Due to levodopa-induced dyskinesia, we try to avoid levodopa in the early stages of the disease and use it only later in more advanced situations in a combination therapy with dopamine agonists. Since IPS is not only based upon dopamine deficiency but also on resulting glutamatergic overstimulation, we advocate the use of a glutamate antagonist such as amantadine or budipine. Catechol-O-methyl inhibitors are very helpful when wearing-off occurs. Anticholinergics are only used in the early stages of tremor-dominant IPS because we fear enhancing the risk of dementia.

    Notes: Abstract The fractionation of carbon isotopes by Methanobacterium thermoautotrophicum was studied during growth of the bacterium on H2 plus CO2 as sole carbon and energy sources. A 80% H2/20% CO2 gas mixture was continuously bubbled through the culture. At high gassing rates, in the absence of a “closed system effect”, cells and methane were found to be depleted in 13C relative to CO2 in the gas mixture by 2.4% and 3.4%, respectively. At low gassing rates, when more than 90% of the CO2 was converted to methane, the cells were enriched in 13C by 1.3% and methane was depleted in 13C by 0.5%; residual CO2 was enriched in 13C by 3.4%. The magnitude of isotope fractionation suggests that CO2 rather than bicarbonate is the active species of CO2 mainly utilized in both CO2 assimilation and CO2 reduction to methane. The apparent positive 13C-discrimination in cell carbon synthesis, which was observed at low gassing rates, indicates that most of the CO2 assimilated into cell material is not incorporated via reactions involved in CO2 reduction to methane.
