Maintenance of the body's perfusion by a total artificial heart (TAH) may result in physiological alterations to the circulatory system. Little has been said about modifications to systemic vascular resistances (SVR) during TAH assistance. This paper reports on two patients implanted with a Jarvik - 70 cc TAH, who died after 1 and 3 days, both with an irreversible drop of SVR related to a complete loss of vascular tone but not related to sepsis. Activation of multiple cascades of inflammation, triggered by the extracorporeal circulation (ECC), is maintained during TAH support. Desperately sick patients might not be able to face the vaso-active situations created by the inflammatory response. 相似文献

A t(8;21)(q22;q22) without blood and bone marrow invasion by immature myeloid precursor cells occurred in a patient previously treated for polycythemia vera. The presence of a molecular rearrangement confirmed that the chromosomal abnormality was identical to that observed in acute leukemia with t(8;21). This case shows that the translocation, t(8;21), may occur in myelodysplasia and suggests that it can precede the appearance of overt leukemia. 相似文献

SUMMARY. To investigate the clinical significance of determination of plasma tissue factor (TF) antigen, we have developed a highly sensitive enzyme-linked immunosorbent assay (ELISA) for plasma TF, using two different monoclonal antibodies against TF apoprotein, 6B4 (catching antibody) and 5G9 (detecting antibody), and tetramethyl benzidine/H2 O2 as substrates. Titration curves of recombinant human TF in buffer containing Triton X-100 were linear within the range from 50 to 2000pg/ml. The total assay time was 3h. Ultracentrifugation and immunoblot analysis indicated that human plasma and urine contained 50 000 g sedimentable and non-sedimentable forms of TF, both of which were detected by our ELISA method.
Plasma and urine concentrations of TF in healthy subjects and patients with various diseases were measured by the ELISA method. In healthy subjects, plasma and urinary TF levels were found to be 149± 72pg/ml (n = 30) and 175±60pg TF/urine creatinine mg (n = 95). respectively. TF was increased in plasma of patients with disseminated intravascular coagulation (DIC), thrombotic thrombocytopenic purpura, vasculitis associated with collagen diseases, diabetic microangiopathy and chronic renal failure receiving haemodialysis, but not in the plasma of endotoxaemic patients without DIC. The plasma TF/serum creatinine ratio did not show a positive correlation. Measurement of TF antigen in plasma may be useful for evaluating the endothelial damage and cell destruction in TF-containing tissues. 相似文献

Primary cardiogenic shock is a common condition with a high mortality rate. In this indication, mechanical assist plays an important part and has improved a lot over the last decade. The authors report their experience with the same assist device in patients with primary cardiogenic shock. Nineteen patients (9 dilated cardiomyopathies, 7 myocardial infarctions, 2 myocardities, 1 undetermined) were treated with an external mechanical ventricular assist device (Thoratec, Berkeley, U.S.). Fourteen patients received a biventricular assist and 5 had a uni-left ventricular assist device. Four of the 19 patients were completely weaned off their ventricular assist after 13, 27, 36 and 94 days, respectively. Ten patients underwent transplantation after an average of 43 days (range 8-95 days). Of the 19 patients, 7 had a portable console allowing autonomous ambulation. Five patients died under mechanical assistance (26.9%) and 3 patients died after transplantation. Three patients required temporary haemodialysis; 4 suffered embolic complications; 4 had mediastinal haemorrhages; 4 had bleeding from other sites, and 6 suffered from late tamponnade. Fourteen patients had at least one infectious episode. The authors conclude that, in patients referred for severe primary cardiogenic shock, the implantation of an external biventricular assist is a reliable option, allowing sequential weaning or being a bridge to transplantation in non-dependent patients, providing they are severely selected. 相似文献

OBJECTIVE: Our aim was to determine whether chorionicity in twin gestations can be diagnosed by use of high-frequency ultrasonography to count the layers of intraamniotic membrane. STUDY DESIGN: This prospective study of 66 twin pregnancies between 13 and 38 weeks' gestation used transabdominal ultrasonography at 10 MHz. The pregnancy was classified as monochorionic when two layers were counted and as dichorionic when three or four layers were counted. The findings of the examiner, who had no other information about chorionicity, were compared with those of the histopathologic examination of the placenta. RESULTS: Ultrasonography allowed chorionicity to be determined correctly in 60 of 63 cases (95%; 100% in the second trimester and 92% in the third). The predictive value for dichorionicity was 100% (48/48) and the sensitivity 94% (48/51). The 12 monochorionic diamniotic pregnancies in which the membrane was visualized were all correctly diagnosed. In a thirteenth case, with severe oligohydramnios, the membrane could not be seen. Two patients were lost to follow-up. In 95% of the cases (63/66) only one examination was required to diagnose chorionicity. Intraobserver variability was 0% (0/26). Interobserver variability, tested by photographs, was 3% (2/65). CONCLUSIONS: This technique should be the first-line method for determining chorionicity in the second and third trimesters because it is the most effective. Its excellent reproducibility may be attributable to the use of high-frequency ultrasonography. (Am J Obstet Gynecol 1996;175:1529-33.) 相似文献

Lupus erythematosus proliferative glomerulonephritis in fetus 总被引:1,自引:0,他引:1
We report the case of a fetus with proliferative glomerulonephritis in the context of maternal systemic lupus erythematosus (SLE). The pattern of the renal lesions correspond to the class III of revisited WHO classification of glomerulonephritis in SLE. Amniotic fluid analysis showed a high level of albumin and the presence of anti-Ro and anti-DNA antibodies that were possibly responsible for the renal injury. 相似文献

We report a case of diprosopus presenting with increased nuchal translucency of 5.3 mm at 14 weeks of gestation. Ultrasonographically, the fetus presented with micrognathia, anterior indentation of the cephalic pole, abnormal cerebral hemispheres with a cystic 4th ventricle and angulation of the spine. The fetal karyotype was normal (46,XX). Following termination of pregnancy, postmortem examination established the diagnosis of diprosopus tetraophthalmus with facial cleft of the 2 faces. 相似文献
