Peripheral total parenteral nutrition employing a lipid emulsion (Intralipid): complications encountered in pediatric patients.

The clinical records of 180 pediatric patients who received Intralipid via peripheral veins at a single institution (1964-1977) were retrospectively analyzed, with particular reference to the complications of this form of therapy. Intralipid was used in a dose range of 2--4 g/kg/day in order to supply 40% of the daily calorie requirements. The patients were neonates, infants, children, and adolescents with a wide range of clinical diagnoses. Local complications associated with Intralipid therapy were minimal. Transient elevations in serum enzyme levels (SGOT, SGPT, and LDH) were observed in 4% of patients, but all of these returned to the normal range after cessation of therapy. Ten patients had histologic evidence of cholestasis, the significance of which is discussed. The lipid emulsion was employed in patients with preexisting hyperbilirubinemia with concomitant resolution of jaundice. Intralipid was administered to patients with known severe thrombocytopenia (secondary to sepsis or myelosuppression) with return of the platelet counts to normal levels during the course of infusion therapy. The use of Intralipid in patients with established sepsis did not delay its response to conventional surgical or antibiotic therapy. There were no instances of the "overloading" syndrome observed.     

Three-dimensional imaging of mitral and tricuspid annuli for total artificial heart implantation

The establishment of a method to clarify the three-dimensional interrelations among the mitral annulus, tricuspid annulus, ascending aorta, and main pulmonary artery, which constitute the interface between the human and total artificial heart (TAH), is essential to the design of the TAH. In a previous study based on transverse magnetic resonance (MR) images of a live human heart, reconstructed images of mitral and tricuspid annuli were found to be deformed. The present study of cadaver and beating hearts revealed that the optimal conditions for atrioventricular annular reconstruction of a beating heart with electrocardiogram-gated MR imaging include use of four-chamber imaging, 5 mm slice thickness, and a slice interval ranging from 5 to 7 mm. Under these conditions, the mitral and tricuspid annuli of 3 beating hearts were reconstructed successfully. It was recognized that during the systolic phase the mitral and tricuspid annuli move anteriorly, leftward and downward, and that in late systole the right lateral margin of the tricuspid annulus is close to the sternum.     

Stoffwechseluntersuchungen unter ergometrischer Belastung bei total duodenopankreatektomierten Patienten

Zusammenfassung Ein Jahr nach totaler Duodenopankmatektomie wurde bei 6 Patienten die exokrine Pankreainsuffizienz geprüft. Diese kann durch orale Gabe von wenigstens 10 g Pankreatin kompensiert werden. Gegenüber 7 Normalpersonen und 6 Typ 1-Diabetikern hatten die Duodenopankreatektomierten unter körperlicher Belastung höhere arterielle Spiegel von Lactat und freiem Glycerin als Ausdruck einer gestörten hepatischen Gluconeogenese bei fehlendem pankreatischem Glucagon. Ihre körperliche Leistungsfähigkeit war auffallend schlecht. Catecholamine stiegen unter körperlicher Belastung nur gering an, Wachstumshormone gar nicht. Diese Resultate sprechen gegen die totale Duodenopankreatektomie als Therapie der chronischen Pankreatitis.

Metabolic investigations under ergometric strain in patients with total duodenopancreatectomy

Summary One year after total duodenopancreatectomy a clinical and laboratory evaluation including exhaustive bicycle ergometry was performed in 6 male patients. The insufficiency of the exocrine pancreas can be compensated by at least 10 g pankreatin per day. During physical exercise patients had higher arterial values of lactate and free glycerol after duodenopancreatectomy than 7 healthy individuals and 6 diabetic patients type 1. This metabolic overreaction was due to a deficiency of pancreatic glucagon and resulted in an impaired hepatic gluconeogenesis. There was no detectable increase in growth hormones and only a small one in catecholamines. The physical condition of patients after duodenopancreatectomy was clearly worse.

Subjective and functional results after total gastrectomy: prospective study for longterm comparison of reconstruction procedures

Background: Many reconstruction procedures have been developed in efforts to resolve patients' complaints after total gastrectomy. However, there have been few reports of longterm comparisons between reconstruction procedures, especially with regard to the prevention of duodenal food passage. This study was undertaken to compare the longterm subjective and functional results among Roux-en-Y esophagojejunostomy (R-Y), R-Y with pouch (P-Y), and jejunal interposition with pouch (P-I) after total gastrectomy. Methods: Consecutive patients requiring curative total gastrectomy were enrolled in this prospective study by the envelope method. Results: Hospital stay was longer following a P-I than an R-Y or a P-Y. Over 50% of R-Y patients complained of heartburn, and 20% of R-Y patients showed dumping syndrome throughout the postoperative period, with this rate being significantly different from rates in the other two groups. P-Y patients complained of early satiety in the late postoperative period, while P-I patients complained of early satiety in the early postoperative period. The nutritional index in P-I patients was higher than those in patients with the other two procedures. Gastrointestinal and hepatobiliary dual scintigraphy (GHDS) showed that the rate of bile reflux with an R-Y was relatively high after surgery. Food reflux with a P-Y was increased (9.4% to 11.1%), but with a P-I food reflux was decreased at 3 years after surgery (13.3% to 9.9%). Patients with a P-Y had a faster recovery of body, weight in the early postoperative period; however, at 5 years after operation, body weight recovery with a P-I was greatest. Conclusion: Reconstruction should be performed with pouch formation after total gastrectomy with curative intent.
