SABATÉ, X., et al. : Washing Machine Associated 50 Hz Detected As Ventricular Fibrillation by An Implanted Cardioverter Defibrillator. This case report describes a patient with an automatic ICD who suffered a defibrillation shock without warning symptoms. An electrical interference can be observed in the stored EGM of the episode. The patient explained that the moment he felt the shock he was touching a washing machine. After correct grounding of this machine the patient did not suffer more inappropriate shocks. 相似文献

The effect of two peptide derivatives of the rat SV-IV (SV-IV/A: 1–70 fragment; SV-IV/B: 71–90 fragment) on human blood coagulation was investigated. The SV-IV/A fragment was found to possess the same procoagulant activity of the native protein, whereas SV-IV/B retained only a very small fraction of the activity. The results obtained strongly suggest that the procoagulant activity of SV-IV/A is due, like SV-IV, to a selective inhibition of the antithrombin III (AT III) activation process induced by heparin, an essential cofactor of AT III. The main data supporting this hypothesis are the following: I) the concentration of active serum AT III decreases when SV-IV/A is present in the clotting system; 2) the plasma treatment with SV-IV/A reduces the concentration of AT III, but not that of other plasma serine protease inhibitors; 3) the recalcification time (RT) of the plasma treated with a rabbit anti-AT III polyclonal antiserum is not modified by SV-IV/A; 4) the presence of SV-IV/A in a reaction mixture containing pure fibrinogen, α-thrombin, heparin. and AT III neutralizes the thrombin inhibition induced by AT III; 5) the concentration of the thrombin-AT III complexes, occurring in sera obtained from CaCl2-coagulated plasma, is markedly reduced in the presence of SV-IV/A; 6) appropriate concentrations of heparin neutralize the inhibitory effect of either SV-IV/A or SV-IV on the AT III activity in vitro. 相似文献

27 cases of primary malignant and benign rib tumours are reported. The most common malignant rib tumour in childhood is Ewing sarcoma (20 cases). Some other rare bone tumours and tumorous conditions (reticulosarcoma, aneurysmal bone cyst, monostotic rib eosinophilic granuloma, osteoid osteoma and lymphangioma) are also described. In the authors' opinion Ewing sarcoma presents with characteristic clinico-radiographic findings in most of the cases. Other monostotic, primary rib tumours and tumorous conditions in childhood — with the exception of exchondroma and enchondroma — rarely show diagnostic radiographic features. 相似文献
