    Notes: Aggregation and gelation of whey proteins induced by a specific protease from Bacillus licheniformis was revealed by turbidimetry, size exclusion chromatography, dynamic light scattering and rheology. The microstructure of the gel was examined by transmission electron microscopy. During incubation of 12% whey protein isolate solutions at 40°C and pH 7, the major whey proteins were partly hydrolyzed and the solution gradually became turbid due to formation of aggregates of increasing size. The viscosity of the hydrolysate simultaneously increased and eventually a gel formed. The gel had a particulate type of microstructure. We hypothesized that the aggregates forming the gel were held together by noncovalent interactions.

    Notes: To obtain information on forces important for maintenance of the structure of heat-set β-lactoglobulin gels, gels set from pure β-lactoglobulin at pH 3.0, 5.0, and 7.0 were solubilized in dissociating buffers, and solubilized material was characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and size exclusion high performance liquid chromatography. The gel formed at pH 7.0 was largely soluble in urea (or SDS), and this gel seemed to be built from covalently linked soluble aggregates, associating into a gel network mainly by strong noncovalent interactions. The gel set at pH 5.0 was solubilized only in the presence of a reducing agent, indicating that this gel structure was supported mainly by covalent disulfide bonds. The gel set at pH 3.0 was almost completely solubilized in SDS or urea without a reducing agent, showing the importance of noncovalent interactions in maintaining the gel structure.

    Notes: Until recently, hypoxaemia was considered as a relative contraindication for liver transplantation. The hepatopulmonary syndrome associated with a right to left shunt of blood through the lungs is reversible in adults and children after correction of the cirrhosis by liver transplantation. However, concerns have been raised regarding the risks of anaesthesia in such hypoxaemic patients. Since the peroperative management of children undergoing liver transplantation and suffering from hepatopulmonary syndrome and severe hypoxemia has never been described, we report here our experience in seven children. Despite the fact that severe arterial desaturation was recorded throughout the procedure, no major complications were recorded peroperatively. The postoperative intubation time was 58 ± 21 h, five children being extubated while still hypoxaemic. All seven patients reversed their hepatopulmonary syndrome after a mean postoperative period of 24±10 weeks. This shows that liver transplantation can be successfully achieved in severely hypoxaemic children and that postoperative correction of the right to left shunt is then obtained.

    Notes: Summary Mortality and long-term neurologic sequelae are still frequent complications of meningitis despite effective antibiotic treatment. This suggests that pathogen-independent inflammatory mechanisms may play an important role in the course of this illness. Neutrophil granulocytes form the primary immune defense in meningitis. Once activated, these cells release elastase into the cerebrospinal fluid (CSF). Elastase may induce tissue damage if local antiproteinase capacity is low as under normal conditions. To define the relevance of this mechanism we studied 22 patients with meningitis. Concentrations of elastase in complex with the main antiproteinaseα 1-proteinase inhibitor (elastase-α 1PI),α 1-proteinase inhibitor (α 1PI), and elastase inhibition capacity (EIC) were measured in CSF of 9 patients with bacterial meningitis (BM), aged 1 month-214 years; 13 patients with non-bacterial meningitis (NBM), aged 1 month–15 years; and 20 patients in whom meningitis was excluded after spinal tap (control group), aged 6 months–15 years. The concentration of elastase-α 1PI in the BM group (median 552 μg/l) was significantly higher than in either the NBM group (median 30 μg/l,p〈0.01) or the control group (median 30 μg/l,p〈0.01). Similarly, theα 1PI-concentration in the BM group was significantly higher (median 113 mg/l) than either the NBM group (median 13.7 mg/l,p〈0.025) or the control group (median 6.3 mg/l,p〈0.001). The concentration of elastase-α 1PI shows a significant correlation with the duration of the infectious symptoms before admission to the hospital (r=0.51,p〈0.02), but not with the number of neutrophil granulocytesr=0.23, p=0.21). Free elastolytic capacity in CSF could be demonstrated in 4 patients: 1 with BM, 2 with NBM, and 1 with pertussis pneumonia and enzephalitis. The measured insufficiency of the proteinase-antiproteinase system may indicate high-risk patients in need of additional anti-inflammatory therapy, e.g., with corticosteroids, during the initial phase of meningitis.

    Notes: Abstract Calcification within active post-transplantation lymphoproliferative disorders has, to our knowledge, never been described. We report the case of a 14-monthold boy who presented 4 months after orthotopic liver transplantation with a primary calcification in a lymphoproliferative nodule involving the hepatic graft. This calcification was detected by routine ultrasonography, visible on plain radiographs, and the post-transplantation lymphoproliferative disorder was histologically proved.

    Notes: Abstract Between 1984 and 1996, the authors performed 499 liver transplants in 416 children less than 15 years old. The overall patient survival at 10 years was 76.5%. It was 71.3% for the 209 children grafted in 1984–1990; 78.5% for biliary atresia (n = 286), 87.3% for metabolic diseases (n = 59), and 72.7% for acute liver failure (n = 22). The 5-year survival was 73.6% for the 209 children grafted in 1984–1990 and 85% for the 206 grafted in 1991–1996. Scarcity of size-matched donors led to the development of innovative techniques: 174 children who electively received a reduced liver as a first graft in our center had a 5-year survival of 76% while 168 who received a full-size graft had a survival of 85% (NS). Results of the European Split Liver Registry showed 6-month graft survival similar to results obtained with full-size grafts collected by the European Liver Transplant Registry. Extensive use of these techniques allowed the mortality while waiting to be reduced from 16.5% in 1984–1990 to 10% in 1991–1992. It rose again to 17% in 1993, leading the authors to develop a program of living related liver transplantation (LRLT). The legal and ethical aspects are analyzed. Between July 1993 and October 1997, the authors performed 53 LRLTs with 90% survival. In elective cases, a detailed analysis was made of the 45 children listed for LRLT between July 1993 and March 1997 and the 79 registered on the cadaveric waiting list during the same period. Mortality while waiting was 2% and 14.5% for the LRLT and cadaveric lists, respectively. The retransplantation rate was 4.6% and 16.1% for LRLT and cadaveric transplants, respectively. Overall post-transplant survival was 88% and 82% for children who received a LRLT or a cadaveric graft, respectively. Overall survival from the date of registration was 86% and 70% (P 〈 0.05) for LRLT or cadaveric LT respectively. The 2-year post-transplant survival in children less than 1 year of age at transplantation was 88.8% and 80.3% with a LRLT or cadaveric graft, respectively; patient survival after 3 months post-transplant was 95.8% and 91.9% for stable children waiting at home, 93.7% and 93.7% in children hospitalized for complications of their disease, and 89.5% and 77.7% for children hospitalized in an intensive care unit at the time of transplantation for children who received a LRLT or cadaveric graft, respectively. It is concluded that LRLT seems to be justified for multidisciplinary teams having a large experience with reduced and split liver grafting.

    Description / Table of Contents: Résumé L'analyse rétrospective de 22 cas d'insulinomes pancréatiques colligés par les auteurs dans leur service leur a permis d'apprécier la valeur diagnostique des différentes méthodes d'exploration pré-opératoires et per opératoires. Dans 18 malades, les insulinomes uniques ont été localisés dans 55.5% des cas par l'artériographie sélective, dans 64% des cas par le cathétérisme transhépatique avec prélèvement étagé de sang veineux, et seulement dans 11% des cas par l'ultfasonographie et la tomodensitométrie. La combinaison de l'artériographie sélective et du cathétérisme transhepatique permit de définir le siège de la tumeur dans 83% des cas. La palpation chirurgicale, l'ultrasonographie au cours de l'intervention, le dosage peropératoire du glucose sanguin permirent dans tous les cas de découvrir une tumeur unique. Lorsque les insulinomes sont multiples les diverses méthodes pré-opératoires d'exploration ne sont pas fiables. Dans 4 cas d'insulinomes multiples les différentes explorations preoperatoires permirent de découvrir seulement 8 (28%) tumeurs sur un total de 28 existantes. On ne peut se fier à la palpation pour les decouvrir. Seuls l'échographie peropératoire et le dosage peropératoire du glucose sanguin décèlèrenttoutes les tumeurs multiples (le diamétre de la plus petite tumeur était de 4 mm). Ces 2 méthodes d'exploration opératoire constituent actuellement les procédés de choix pour mettre en évidence les petits insulinomes pancréatiques.
    Abstract: Resumen Se ha hecho la determinación del valor diagnóstico de diversos procedimientos de localización pre- e intraoperatoria mediante el anâlisis retrospectivo de 22 casos de insulinoma pancreáticos operados en nuestro centra médico. En los 18 pacientes, los insulinomas solitarios pudieron ser localizados por arteriografía selectiva (AS) en 55.5% de los casos, por cateterismo transhepático para muestreo venoso esplénico (MVET) en 64% de los casos, pero por ultrasonografía (US) y tomografía computadorizada (TC) apenas en 11% de los casos. La combinación de AS y MVET logró la localización preoperatoria del tumor en 83% de los casos. La palpación intraoperatoria, la ultrasonografía, y la monitoría de la glicemia logró la localización del tumor en la totalidad de los otros casos que poseían un tumor único. Cuando los insulinomas eran multiples, los diversos exámenes preoperatorios demostraron no ser confiables. En los 4 casos con insulinomas múltiples, varios exámenes (AS, US, TC, MVET) lograron localizar solo 8 (28%) tumores entre 28. La palpación intraoperatoria fue igualmente inadecuada. Sólo la US intraoperatoria y la monitoría continuada de la glicemia lograron la localización de latotalidad de los tumores multiples, siendo 4 mm el diámetro del más pequeño de los tumores. Estos 2 tipos de examen intraoperatorio representan actualmente los procedimientos de elección para detectar pequenos insulinomas pancreáticos.
    Notes: Abstract From a retrospective analysis of 22 cases of pancreatic insulinoma operated in our center, we have determined the predictive value of various pre- and intraoperative localization procedures. In 18 patients, solitary insulinomas were localized by selective arteriography (SA) in 55.5% of cases, by transhepatic catheterization with pancreatic venous sampling (THVS) in 64% of cases, but by ultrasonography (US) and computed tomography (CT) in only 11% of cases. The combination of SA and THVS allowed the preoperative localization of the tumor in 83% of cases. Intraoperative palpation, ultrasonography, and blood glucose monitoring localized a single tumor in all cases. When the insulinomas were multiple, the various preoperative investigations were not reliable. In the 4 cases of multiple insulinoma, various investigations (SA, US, CT, THVS) localized only 8 (28%) tumors of 28. Intraoperative palpation was also unreliable. Only intraoperative ultrasonography and continuous blood glucose monitoring localizeall multiple tumors (the diameter of the smallest tumor was 4 mm). These 2 intraoperative investigations are now the procedures of choice for the detection of small pancreatic insulinomas.

    Notes: Abstract In this study, 8 years experience of early percutaneous peritoneal dialysis (PPD) in the treatment of acute necrotic hemorrhagic pancreatitis (ANHP) are presented. The introduction of methemalbuminemia and the presence of specific ascites rich in amylase, lipase and methemalbumin as early indicators of the presence of ANHP enabled us to confirm the diagnosis in 53 patients, after which early institution of PPD was possible. Thirty patients survived by PPD alone and 9 patients survived by the combination of PPD and surgery, giving an overall mortality rate of 26.4%. A better survival rate of patients having a high Ranson prognostic score was obtained. The introduction of computerized axial tomography (CAT), in 1980 into our hospital allowed us to use this technique for followup. This change and the fact that we were more experienced with PPD, divided our study into two periods: 1976 to 1979, 22 patients; 1980 to 1983, 31 patients. A more aggressive medical approach to treating ANHP was observed during the second period. Surgery was delayed compared to the first period and confined to treating late complications, such as infections, by drainage procedures. Despite the fact that the results were not statistically different, a trend towards a lower mortality rate (19.3%) in the second period compared to the first period (36%) was obtained.
