    Description / Table of Contents: Summary Serum digoxin concentration and half-life were radioimmunologically determined in 9 mature newborns after 7 days medication with digoxin. The newborns were in respiratory distress treated with continuous positive airway pressure or were suspected to have serious congenital heart disease. Loading dose was 26 µg/kg body weight intravenously and 35 µg/kg body weight orally, respectively. Maintenance dose corresponded to 1/8th of the digitalization dose twice daily. The serum digoxin level 12 h after the last dose varied between 1.4 and 2.5 ng/ml (mean 2.0 ng/ml, Sx=0.4). The serum half-life of digoxin varied between 21.7 and 42.4 h (mean 30.0 h, Sx=7.7). The mean serum half-life of digoxin of 30 h attained values found in adults without renal disease. This suggests that the serum digoxin levels of newborns which are usually higher if compared with those of adults result from higher digoxin doses per unit body weight and not from diminished digoxin elimination.
    Notes: Zusammenfassung Bei 9 reifen Neugeborenen wurden nach 7tägiger Digoxin-Behandlung Serum-Spiegel und Halbwertszeit von Digoxin radioimmunologisch ermittelt. Die Behandlung erfolgte wegen eines Atemnotsyndroms, das mit kontinuierlich positivem Atemwegsdruck behandelt wurde, oder wegen Verdachts auf schwerwiegenden angeborenen Herzfehler. Die Sättigungsdosis betrug 26 µg/kg bei intravenöser bzw. 35 µg/kg bei oraler Applikation. Die Erhaltungsdosis betrug zweimal täglich 1/8 der Aufsättigungsdosis. Die Digoxin-Spiegel 12 h nach der letzten Dosis variierten zwischen 1.4 und 2.5 ng/ml (Mittelwert 2.0 ng/ml, Sx=0.4), die Halbwertszeit zwischen 21.7 und 42.4 h (Mittelwert 30.0 h, Sx=7.7). Die mittlere Halbwertszeit von 30 h liegt in einer Größenordnung, wie sie bei nierengesunden Erwachsenen gefunden wird. Man kann daher vermuten, daß die im Vergleich zum Erwachsenen gewöhnlich höheren Serum-Digoxin-Spiegel des Neugeborenen Folge einer höheren Digoxindosis pro kg Körpergewicht und nicht einer verminderten Elimination sind.

    Description / Table of Contents: Zusammenfassung Wir untersuchten die Plasma-Digoxin-Konzentrationen während der Erhaltungstherapie mit Digoxin bei unreifen und reifen Neugeborenen, Säuglingen, Kindern und Erwachsenen. Die Plasma-Digoxin-Konzentration der Neugeborenen war signifikant höher als diejenige der Erwachsenen; zusätzlich in der Gruppe der unreifen Neugeborenen auch höher als bei Säuglingen und Kindern. Diese Unterschiede in den Plasma-Digoxin-Konzentrationen erklären sich durch Unterschiede in der Dosis, dem Verteilungsraum und der Exkretionsrate von Digoxin in den einzelnen Altersgruppen.
    Notes: Summary Plasma digoxin concentration during maintenance therapy with digoxin was determined in premature and mature newborns, infants, children and adults. The plasma digoxin concentration of newborns was significantly higher than in adults; in addition, in the group of premature newborns it also was higher than in infants and children. These differences in plasma digoxin concentrations may be explained by differences in dose, volume of distribution and excretion rate of digoxin in the various age groups.

    Notes: Abstract A 12-year-old boy with aplastic anemia developed severe but reversible cardiac failure after treatment with 200 mg/kg cyclophosphamide (4×50 mg/kg on four consecutive days) given as preparation for bone marrow grafting. This and previously reported cases demonstrate the possibility of cardiotoxicity after high doses of the drug.

    Notes: Abstract Postmortem tissue and plasma concentrations of digoxin were studied in 13 premature newborns, 6 mature newborns, and 5 older infants (age 1 to 14 months). The pertinent results of our study are as follows: The tissue digoxin concentrations tend to be higher in premature and mature newborns than in infants. This difference is statistically significant with respect to the concentration in myocardium and skeletal muscle. The renal digoxin concentration of premature newborns is significantly lower than that of mature newborns, the tissue concentrations in the other organs examined being essentially equal. In all age groups examined, skeletal muscle contains the greatest portion of digoxin, followed by the liver. The relation of myocardial to plasma digoxin concentration shows no significant difference between the various age groups. Within the groups, the variation is relatively large.

    Description / Table of Contents: Summary An Ivalon-plug (PDA-plug) has been developed for transvenous closure of patent ductus arteriosus. It can be introduced into the ductus through standard venous sheaths with a diameter von 8–16 French. The plug is fixed in its target position by means of four distal (aortal) and two proximal (pulmonary) nitinol struts. In case of malpositioning the system can be pulled back into and retrieved through the sheath. In animal experiments endothelialization of the implanted material was demonstrated. PDA-closure was attempted in 58 patients; the procedure was successful in 57 cases; a residual ductal flow was present in eight patients. During a follow-up of up to 24 months there were no complications.
    Notes: Zusammenfassung Es wurde ein Ivalonpfropf (PDA-Plug) zum transvenösen Verschluiß des persistierenden Ductus arteriosus entwickelt. Er kann durch Standardschleusen vom Kaliber 8–16 French in den Ductus eingeführt werden. Mit 4 distalen (aortalen) und 2 proximalen (pulmonalen) Nitinol-Federbeinchen wird das System im Ductus fixiert. Bei Fehlplazierung kann der Propf in die Schleuse zurückgezogen und entfernt werden. In Tierexperimenten wurde eine Endothelialisierung des implantierten Materials nachgewiesen. Bisher wurde bei 58 Patienten ein Ductusverschluß versucht; in 57 Fällen gelang der Eingriff, ein Residualshunt war bei 8 Patienten nachweisbar. Im Verlauf von bis zu 24 Monaten traten keine Komplikationen auf.

    Notes: Abstract A new computer-based navigation system for spinal surgery has been designed. This was achieved by combining intraoperative fluoroscopy-based imaging using conventional C-arm technology with freehand surgical navigation principles. Modules were developed to automate digital X-ray image registration. This is in contrast to existing computed tomography- (CT) based spinal navigation systems, which require a vertebra-based registration procedure. Cross-referencing of the image intensifier with the surgical object allows the real-time image-interactive navigation of surgical tools based on one single registered X-ray image, with no further image updates. Furthermore, the system allows the acquisition and real-time use of multiple registered images, which provides an advanced multi-directional control (pseudo 3D) during surgical action. Stereotactic instruments and graphical user interfaces for image-interactive transpedicular screw insertion have been developed. A detailed validation of the system was performed in the laboratory setting and throughout an early clinical trial including eight patients in two spine centers. Based on the resulting data, the new technique promises improved accuracy and safety in open and percutaneous spinal surgery.

    Notes: Abstract 127 Latino adults responded to a survey concerning physical activity. Respondents over-represented well educated and middle class Latinos. Subjects reported a mean of 48 minutes/week of walking for exercise. This sample reported less than two episodes per week of vigorous physical activity, again below the recommended 3/wk needed to insure cardiovascular fitness. We expect more representative samples to engage in less physical activity. Stepwise multiple regression analyses were conducted using 24 variables based on Social Learning Theory. A multiple R of 0.66 accounted for over 27% of the variance in walking for exercise (p〈0.001). Older adults, those with a history of childhood injury, and those who reported friend support were more likely to walk for exercise. Respondents who participated in physical activity during childhood and adolescence (including formal physical education in school) and, paradoxically, those who had models for exercise in childhood were less likely to walk for exercise. A multiple R of 0.75 accounted for 43% of the variance in vigorous physical activity and reached significance (p〈0.001). Self-efficacy, friends' support, childhood physical activity, and eating a heart healthy diet were positively related to vigorous activity. These results suggest that different correlates influence walking versus vigorous activity, and that correlates of physical activity are different for Latinos compared to Anglos. The findings emphasize the need for larger scale investigations of the determinants of activity within the Latino population.
