Enzyme-linked immunosorbent assay (ELISA) for streptokinase antibodies.

A micro plate Enzyme-linked immunosorbent assay (ELISA), developed for detection of antibodies to Streptokinase, was used to analyze 80 human sera. The aim was to provide a simple method for antibody screening that required neither sophisticated equipment nor a high degree of technological skill. Preliminary results show that ELISA is specific, reproducible and sensitive. Comparative evaluation of the ELISA and the coagulum lysis test for antibodies against streptokinase show excellent correlation. We also evaluated the anti-Streptolysin O titer either by conventional method or ELISA. The sensitivity of ELISA for detecting anti-Streptolysin O antibodies was 3-4-fold higher than that of the hemolytic test. The sensitivity of ELISA for detecting anti-streptokinase antibodies was 10-20-fold higher than that of the coagulum lysis. The Enzyme-linked immunosorbent assay seems to offer some advantages over the more commonly used coagulum lysis test as far as sensitivity is concerned and potentially it is suggested that this method could be usefully employed clinically in human streptococcal infections.

[Radiological aspects of viral respiratory diseases].

The importance of radiological examination in viral diseases of the respiratory apparatus depends on the site and the type of alterations caused, since the evidence of damage it provides is closely linked to the anatomical and pathological of such alterations. In the case of the upper airways, trachea, and large bronchi, little radiological evidence of the mostly mucosal lesions will be obtained, except in laryngeal forms in children with considerable oedema. Generally speaking, the chances of demonstration are greater in diseases affecting the lung parenchyma, with direct or indirect ventilation changes. Interstitial involvement, which is characteristic of such diseases, will be less easy to demonstrate, especially in the initial stages, on account of the absence of distinct gross evidence of the alteration, irrespective of the clinical picture.

[Radiological aspects of viral respiratory diseases in adults].

Adults present few radiological signs of damage to the air ways caused by viral agents whereas the importance of such study is much greater in lung pathology, particularly in the course of pneumonia and bronchopneumonia. Typical of this group of disease is the involvement of the interstice which is normally great enough to be detected in X-rays. The different causal agents generally present in their own preferential ways, but specific diagnosis using X-rays signs alone is in practice impossible. At best, some suspicion might be advanced regarding a non-bacterial form as the notable morphological resemblances in fact prevent differential diagnosis among the different virosis forms as well as their distinction from pneumopathies due to Mycoplasma pneumoniae.

[Post-traumatic pulmonary hematoma].

Pulmonary haematoma is relatively rare. Though on the increase as a consequence of a rise in the number of road accidents, it is not necessarily traumatic in origin. Three cases (two post-traumatic, out of 250 serious chest trauma cases examined) observed at the University of Turin chest and lung surgery centre over the last three years are presented. Data from the literature are also cited. A description is given of the typical radiological features: roundish opacity with distinct edges, homogeneous, in the site the pulmonary or subpleural ligament, slow involution. This picture may be sufficient for diagnosis when the history is not clear.

[Abnormal pulmonary vein outlet. Radiological aspects (author's transl)].

6 cases of abnormal pulmonary venous outlet, 5 of them partial anomalies without cardiocirculatory symptoms, are reported. Diagnosis was formulated by means of angiocardiography resorted to on the basis of the radiographic picture: retraction of the right hemithorax (left in 1 case), heart attraction, pulmonary veiling, tomographic pictures of anomalous vessels.

Effect of preoperative radiological treatment of hepatocellular carcinoma before liver transplantation: a retrospective study.

PURPOSE: To assess the results of radiological treatment of patients with hepatocellular carcinoma (HCC) performed before orthotopic liver transplantation (OLT). METHODS: Sixty-two transplanted patients with a total of 89 HCC nodules were studied; 50 lesions in 38 patients had been treated prior to OLT with transcatheter arterial chemoembolization (TACE; n = 29), percutaneous ethanol injection (PEI; n = 10), or combined therapy (TACE + PEI; n = 11). The induced necrosis was pathologically evaluated. The recurrence rate after OLT in the treated group of patients (n = 38) was compared with that in the non-treated group (n = 24). RESULTS: After TACE, necrosis was complete in 7 of 29 lesions (24.1%), partial in 11 of 29 (37.9%), and absent in 11 of 29 (37.9%). After PEI, necrosis was complete in 8 of 10 lesions (80%), and partial in 2 of 10 (20%). Using combined therapy, necrosis was complete in 11 of 11 lesions (100%). Four of 24 untreated and 4 of 38 treated patients did not survive OLT from causes not related to the HCC; 3 of 20 non-treated patients (15%) and 4 of 34 treated patients (11.8%) had post-OLT recurrence (these last four patients had undergone only TACE and did not have tumor necrosis at pathological examination). CONCLUSION: TACE of HCC prior to OLT had no influence on the recurrence rate. PEI and combined therapy (TACE + PEI) may be recommended in patients awaiting OLT.

[The transcatheter recanalization of occluded portosystemic shunts].

UNLABELLED: The authors present their personal experience in percutaneous treatment of portosystemic shunt occlusion and stenosis by percutaneous transluminal angioplasty (PTA) and fibrinolytic local infusion. Twelve patients with portosystemic shunt stenosis or occlusion were percutaneously treated. In 8 patients only PTA was performed, 4 were treated with local fibrinolytic infusion, in 3 of the latter cases this treatment was followed by PTA. In all 12 patients recanalization was successful and non complications arose. Six patients died in the following 15 months, none due to rebleeding. In 5 of these patients the shunt was patent at post-mortem examination. In the 6 patients still alive in the follow-up period (2 to 25 months, mean 14.5 months) the shunt was patent in 4 and occluded in 2. IN CONCLUSION: percutaneous treatment with PTA or fibrinolytic local infusion is preferable in non-functioning portosystemic shunt; further surgery is always extremely risky in such patients.

[Hemobilia following biliary drainage: percutaneous treatment with arterial embolization and biliary fibrinolysis].

The Authors report a case of haemobilia following the performance of biliary drainage. Angiography of the celiac tripod and superior mesenteric artery was carried out in order to evidence the lesion and to perform, during the same session, embolization of the leaking vessel by means of fibrin sponge particles (Spongostan). Subsequent cholangiographic controls demonstrated the presence of bile ducts clots then treated by loco-regional infusion of urokinase. On the basis of the Authors' personal experience, the combination of loco-regional biliary fibrinolytic treatment and embolisation leads to the resolution of the cause of hematobilia and of retention jaundice.
