New Japanese diagnostic criteria were prepared for disseminated intravascular coagulation (DIC) in critically ill patients and their usefulness was compared with the criteria of the International Society of Thrombosis and Haemostasis (ISTH) and those of the Japan Ministry of Health and Welfare (JMHW). In a retrospective study of patients with platelet counts of less than 150 x10(3)/mL, 52 cases (33.3%), 66 cases (42.3%), and 101 cases (64.7%) were diagnosed as DIC by the ISTH, JMHW, and new Japanese DIC criteria, respectively. The DIC state as diagnosed by the new Japanese DIC criteria included both DIC states as diagnosed by ISTH or JMHW criteria. Some DIC states diagnosed by the JMHW criteria included those diagnosed by ISHT criteria but this was not universal. The mortality of DIC as diagnosed by the ISTH or JMHW criteria was markedly high, compared to that for DIC diagnosed by the new Japanese criteria. The mortality of patients without DIC by ISTH was also high when they were diagnosed as DIC by the new Japanese criteria. The frequency of DIC by each set of diagnostic criteria was significantly higher in patients with infection than in those without infection. The mortality of DIC by each set of diagnostic criteria was significantly higher in patients with infection than in those without infection, and the mortality of overt-DIC by ISTH diagnostic criteria was also high in patients without infection.

PGE1 suppressed the production of IL-6 and IL-8 but not IL-10, IL-1ra, sTNF RI, or sTNF RII. The change in the balance between pro-and anti-inflammatory cytokines may be one of the most important cytoprotective mechanisms of PGE1.

Severe effects following acute glufosinate poisoning were associated with two positive SIRS criteria. A low P/F ratio may be useful for predicting the occurrence of respiratory complications.

We investigated the perioperative serum procalcitonin (PCT) concentrations in 5 consecutive patients who underwent surgery for acute aortic dissection (2 men, 3 women; mean age 72 ± 9 years, age range 52–81 years). Surgery used cardiopulmonary bypass with deep hypothermic circulatory arrest. Blood samples were taken prior to surgery, upon arrival in the intensive care unit, and 6, 12, 18, 24, and 48 h after intensive care unit arrival. Prior to surgery, the PCT level was 4.2 ± 3.4 (range 0.8–8.3) ng/ml. The PCT increase was greatest at 24 h (5.8 ± 4.5 ng/ml). Preoperatively, the C-reactive protein concentration was 8.0 ± 8.3 (range 0.9–23.8) mg/dl, and the white blood cell count was 8.5 ± 3.1 × 10³. C-reactive protein continued to increase at 48 h, while the white blood cell count peaked at 24 h. In spite of no symptoms of infectious diseases or septicemia, all patients had a significant preoperative PCT elevation. This finding may have something to do with the specific preoperative condition of acute aortic dissection. However, more clinical investigation is needed to clarify the PCT changes during and after surgery for acute aortic dissection.
