    Soluble P-selectin and the postoperative course following cardiopulmonary bypass in children (2001)

    Notes: Background: Cytokine-inducible leucocyte-endothelial adhesion molecules were shown to affect the postoperative inflammatory response following cardiopulmonary bypass (CPB). Soluble P-selectin (sP-selectin) is one of these molecules. We investigated the correlation between plasma sP-selectin levels and the intra- and postoperative course in children undergoing CPB. Methods: Serial blood samples of 13 patients were collected preoperatively upon initiation of CPB and seven times postoperatively. Plasma was recovered immediately and frozen at – 70°C until use. Circulating soluble selectin molecules were measured with a sandwich enzyme-linked immunoabsorbent assay technique. Results: The significant post-CPB changes in sP-selectins plasma levels were associated with patient characteristics, operative variables and postoperative course. sP-selectin levels correlated significantly with surgery time, aortic cross-clamping time and inotropic support, as well as with the postoperative Pediatric Risk of Mortality score, hypotension and tachycardia. Conclusions: A relation between CPB-induced mediators and both early and late clinical effects is suggested. The up-regulation and expression of sP-selectin indicate neutrophil activation as a possible mechanism for the increase, and inhibiting it may reduce the inflammatory response associated with CPB.

    Notes: Summary A 6-year-old child was found under a heavy bookcase that compressed her chest. On admission to the emergency room she was found to be dyspneic with a systolic murmur and complete atrioventricular (A-V) block. Her condition deteriorated rapidly, leading to cardiogenic shock and loss of consciousness. Echocardiographic Doppler evaluation demonstrated a large ventricular septal defect and tricuspid insufficiency. A pericardial patch was put over the tear in the septum, and torn chordae tendinae were reimplanted to the papillary muscles. A pacemaker was inserted. Her situation improved, but on the third day cardiogenic shock and right ventricular dysfunction ensued and the patient expired. A review of the previous 13 cases from the pediatric literature is presented.

    Notes: Zusammenfassung Natriumtripolyphosphat wird von Kaolinit und Montmorillonit aus wÄ\riger Lösung gemÄ\ einer Freundlichschen Isotherme adsorbiert. Die adsorbierte Menge steigt mit steigender Temperatur, ist also durch eine Reaktion mit Aktivierungsschwelle bedingt. Nach der Adsorption setzt eine langsame Zersetzung der Tonminerale ein, in deren Verlauf lösliche SiO2 und Al-Polyphosphat in der Lösung erscheinen. Al und SiO2 werden in der Lösung im selben VerhÄltnis wie in den Mineralen gefunden. Durch diesen Zersetzungsproze\ verlieren die Minerale die FÄhigkeit, weiterhin Polyphosphat adsorptiv zu binden.
