As the initial problems of trauma have been resolved, patients may survive the immediate period following critical injury only to succumb later to the effects of sepsis. We previously noted a correlation between multiple organ failure and intravascular clotting. The present study evaluated the incidence of infection complications following proven disseminated intravascular coagulation. Detailed analysis of multiple clotting factor changes following critical surgical illness (Factors I, II, V, VIII, IX, X, XI, and platelets, fibrin degradation products and plasminogen) were carried out prospectively in 48 patients. Twenty-one of the 48 were classified as having a severe degree of intravascular coagulation on the basis of hematologic evidence. Only one survived without evidence of infection; 16 showed changes consistent with a moderate degree of intravascular coagulation, and ten subsequently developed evidence of infection. Of the 11 patients with minimal evidence of intravascular coagulation, infection developed in only one.

After a brief survey of some physiologic properties of Von Willebrand factor activity (VIII r WF) the numerous clinical states with an increase of this activity are described. The authors report their own results concerning sepsis, chronic arteritis of lower limbs, diabetes, toxemia of pregnancy. In most cases the increase of VIII r WF activity appears as a sign of vascular injury and/or the consequence of tissular damage.

Amongst the 4,500 strains of our collection of Yersinia enterocolitica usually non-pathogenic for laboratory animals, 5 or 6 strains appeared to be naturally pathogenic for mice. Using these strains and non-pathogenic strains representing more than 90 per cent of human isolates in the world (biotype 4, serotype 0:3, phagocyte VIII; biotype 2, serotype 0:9, phagotype X3), the pathogenicity for cyclophosphamid treated mice and athymic Nude mice has been tested. Highly pathogenic strains killed conventional as well as cyclophosphamid treated mice. Non-pathogenic strains for conventional mice did not show any pathogenicity for cyclophosphamid treated mice (strain IP161 excepted) but killed 30 athymic Nude mice inoculated with 5 x 10(8) and 5 x 10(5) organisms by the oral or intraperitoneal routes. Nude mice infected intragastrically or intraperitoneally showed signs of enteritis and bronchopneumonia followed by a septicemia. Abscesses were found in the liver, the spleen and the ileal wall. The infection of Nude mice with Y. enterocolitica resembles naturally acquired human infection where 2/3 of the cases are enteritis among under 4-year-old children and where septicemia occurs among immunologically deficient adults. The role of T-lymphocytes and of immune functions in Y. enterocolitica infection is discussed through our model.

Primary liver cancer (PLC) of the hepatic hilus was designated as a tumor situated at the main branch of the portal vein or pedicle of the hepatic veins in contact with the intrahepatic vena cava. That is, the main tumor located at segment I, IV, V, or VIII and concentrating on the central part of the liver was called "the central type of PLC," which differed from a tumor located at segment II, III, VI, or VII; the latter was called "the peripheral type of PLC." Surgical treatment of the PLC has been significantly improved in the past two decades, but the resection of the central type of PLC is difficult and hazardous. This institution admitted 903 PLC from January 1970 to April 1988, of which 118 cases were the central type; 65 cases were resected successfully, a resectability of 55.1%. One patient died from sepsis within 1 month of operation (mortality 1.53%). The modes of operation for the different segments are described, and suggestions for improvements are presented. The survival rates were compared with a similar number of patients with the peripheral type of tumor in the same period and treated by the same surgeons. The results show noticeable differences. The one-year, three-year, and five-year survival rates after resection were 70.9%, 43.2%, and 39.2% in the central type of PLC; they were 98.3%, 85.0%, and 76.4% in the peripheral type of PLC (P less than 0.001). Further discussion of improvements in surgical techniques and mental awareness are suggested.

Seven hundred fifty-eight unselected children entered into the United Kingdom Medical Research Council acute lymphoblastic leukaemia UKALL VIII Study and Trial were studied for differences in early treatment-related toxicity according to the type of intramuscular L-asparaginase received. Two hundred seventy-five received a product obtained from Escherichia coli and 483 the enzyme from Erwinia chrysanthemi. The E. coli patients had a significantly higher incidence of neurotoxicity, pancreatitis, and life-threatening sepsis (4%, 2%, and 20%, respectively) when compared with the Erwinia group (2%, 0%, and 18%). Severe hypersensitivity was seen in one patient from both groups and the incidence of glucose intolerance was not significantly different. These findings indicate that E. coli asparaginase may be more toxic. With a minimum follow up of 4 1/2 years there is no evidence that either product has made a significantly different contribution to disease-free survival.

Impaired fibrinolysis may contribute to development of adult respiratory distress syndrome (ARDS). Pathologic increases in endogenous plasminogen activator inhibitor (PAI-1) may blunt normal fibrinolysis and unmask alternate fibrinolytic mechanisms, such as elastase-induced fibrin degradation. We measured PAI-1 and elastase-induced fibrin(ogen) degradation products in 69 critically ill patients in our medical intensive care unit (MICU) and in nine healthy volunteers. Factor VIII-related antigen protein (VIII:Ag), a reported marker of acute lung injury, and alpha-1-protease inhibitor (alpha-1-PI), an acute phase reactant, were also measured. MICU patients included 24 control patients with no known risk of ARDS, 35 patients with risk factors for ARDS including sepsis, pneumonia, aspiration, and shock, and 12 patients with ARDS including two patients from at-risk groups who developed ARDS. Plasma PAI-1 was determined by chromogenic assay, elastase-induced peptides by a new radioimmunoassay, VIII:Ag by immunoelectrophoresis, and alpha-1-PI by immunodiffusion. When compared to normal volunteers, MICU control patients had elevated PAI-1, VIII:Ag, elastase-induced peptides, and alpha-1-PI. Patients with ARDS had significantly higher PAI-1 and VIII:Ag than did MICU control patients; elastase-induced peptides and alpha-1-PI were not higher. However, at-risk patients who did not develop ARDS also had high PAI-1 or VIII:Ag. Although these data cannot refute the possible role of these compounds in the pathogenesis of ARDS, they demonstrate that PAI-1 and VIII:Ag may be elevated in many critically ill patients but may not be useful markers for the subsequent development of ARDS.

A 42-year-old Factor-VIII-deficient hemophiliac developed an infected pseudocyst and subsequent clostridial sepsis. Wide surgical debridement and precise medical management provided for survival in this patient's case. The treatment of choice for this rarely encountered problem was radical excisional surgery along with antibiotics and replenishment of all necessary blood products.

Four patients with hemophilia A have undergone liver transplantation in our institution, three successfully. The first was a 21-year-old man with chronic active hepatitis (CAH) in whom the effects of previous abdominal operations prevented the satisfactory technical insertion of the new liver. He died intraoperatively. The second patient was a 15-year-old boy with CAH who began to synthesize factor VIII coagulant activity (F VIII:C) within 18 hours of successful liver transplantation and has continued to do so for almost 2 years (F VIII:C range 0.89 to 3.20 U/mL). The first 2 months of his postoperative course were complicated by infections, but since that time he has done well and has returned to school. The third patient was a 48-year-old man with portal fibrosis and severe ascites. He synthesized F VIII:C (range 0.96 to 1.50 U/mL) within six hours after reestablishment of circulation through the new liver. His postoperative course was complicated by numerous infections, and he died with sepsis and an acquired immunodeficiency-like syndrome 4 months after transplantation. The fourth patient was a 47-year-old mild hemophiliac with CAH who produced adequate factor VIII:C levels following transplantation (range 0.79 to 2.80 U/mL). These patients demonstrate that liver transplantation in hemophiliacs with end-stage liver disease may be lifesaving and results in correction of the F VIII:C deficiency and associated hemorrhagic tendency.

Life-threatening human sepsis is often treated using bolus intravenous aminoglycoside injections with transient deafness as a reported side effect. Young adult cats were given various high dosages of gentamicin in bolus injections (1 ml in 30 s). Scala vestibuli calcium and gentamicin, blood gentamicin and compound action potentials of the VIII nerve were measured shortly after the injections and 45 min later. An obvious relationship could be demonstrated between levels of gentamicin, decreased calcium content and acoustic thresholds elevation. Even after a high dose of 175 mg/kg that abolished action potentials at t = 2 min, recovery invariably occurred. It is believed that the reported transient hearing loss in humans may be partly attributable to a temporary blockage of calcium by gentamicin.

Tissue thromboplastin generation in monocytes was studied during various stages of Escherichia coli endotoxinaemia in pigs. The pigs were monitored in halothane anaesthesia and mechanically ventilated. Blood was sampled from the superior caval vein before and during endotoxin infusion and up to 6 hours after its start. Monnuclear leukocytes were harvested with Lymphoprep separation and monocyte counts were made, using TRITC-labelled sheep erythrocytes, acridine orange and a fluorescence microscope. Thromboplastin was quantified in a two-stage assay by incubating the test sample together with purified factor X, factor VII and Ca++. The generated factor Xa was thereafter assayed. There was statistically significant increase of tissue thromboplastin activity in monocytes after endotoxin infusion. Maximum level was reached at the end of the infusion and was maintained throughout the observation period. Decrease occurred in platelets, leukocytes, antithrombin III, fibrinogen and clotting factors V, VII and VIII, and clotting time was prolonged. These findings indicated significant disseminated intravascular coagulation. The endotoxin-stimulated monocytes with their elevated tissue thrombo-plastin activity thus may play an important part in development of the DIC which so often follows septicemia.
