The radio-fibrinogen test is a simple and sensitive method for diagnosing deep vein thrombosis. Intravenously administered radioactive labelled fibrinogen is incorporated as radioactive fibrin in freshly developing thrombi, and such labelled thrombi may be detected on the body surface with nuclear medical equipment. Homologous iodine 125 labelled fibrinogen is chiefly used since it is known not to transmit viral hepatitis. The weak gamma emittor 125-I allows the use of a portable scintillation detector rate meter with an easily moved measuring device. This bedside method does not involve discomfort for the patient. The correlation between ascending phlebography and the radioactive fibrinogen test is more than 90 percent. The radiofibrinogen test may be used to study thromboembolic diseases, to evaluate drugs for prevention of thromboembolic complications and to confirm clinically suspected fresh deep vein thrombi. Details of the method as used in several thousand measurements are given.

1. The purpose of fluid administration is not only the restoration of blood volume but also the normalization of impaired nutritive flow. 2. Plasma oncotic (colloid osmotic) pressure is the only force which can draw water into the circulation. In shock the infusion of colloid solutions is able to normalize nutritive flow and peripheral resistance almost at once. 3. Five per cent solutions of pasteurized plasma protein or albumin and 6 per cent dextran 70 yield a volume expansion corresponding to the amount infused. 4. The decrease in hematocrit produced by the infusion of these three colloidal solutions is accompanied by a decrease in whole blood viscosity resulting in a rise in cardiac output as well as in nutritional tissue flow. 5. Hemodilution improves oxygen supply as long as the hematocrit does not fall below 30 per cent, although normovolemia is the critical requirement. 6. Transmission of viral hepatitis is still the greatest danger of blood transfusion. 7. The use of large amounts of Ringer's lactate is not advised, as this solution does not reduce the total number of units of blood which need to be given. Pulmonary edema may become a problem. 8. Dextrans are best suited to initial volume replacement in shock. They increase plasma volume, improve blood flow, have antithrombotic properties, and are easily available and relatively cheap. Anaphylactoid reactions are rare. 9. Every third patient undergoing general surgery and every other patient having hip surgery develops a deep venous thrombosis. Widespread prophylaxis to prevent thromboembolic complications is mandatory. 10. The antithrombotic properties of dextran are due to a reduction in platelet adhesiveness, a change in fibrin clot structure, and the increased lysability of thrombi and the improvement of blood flow. 11. In a personal controlled, prospective, randomezed trial comparing subcutaneous heparin and intravenous dextran 40, 35.8 per cent of the controls (n=95), 13.2 per cent of the 83 patients in the heparin group, and 20.5 per cent in the dextran group (n=83) developed deep venous thrombosis. The difference between dextran and heparin is not significant; however, both treatment groups show a statistically significant effect compared to the controls.

Serum specimens for anti-nuclear fluorescence tests are routinely received in our laboratory. Four specimens were spotted to be negative for anti-nuclear fluorescence but positive for fluorescence characteristic of that caused by anti-golgi antibodies. (a) Patient A had acute glomerulonephritis; (b) Patient B had acute viral hepatitis; (c) Patient C had deep vein thrombosis; and (d) Patient D had non-Hodgkin's lymphoma. The relevance and possible aetiology of anti-golgi antibodies are also discussed.

Hepatocellular carcinoma has a tendency to invade vascular structures. However, extension into the hepatic veins or heart is uncommon. We describe the case of a 68 years old man with chronic viral hepatitis type C, consulting about edema and pain in his left leg. Doppler scan showed deep venous thrombosis in that level and computed tomography of thorax and abdomen showed complete thrombosis of the inferior cava vein, thrombosis of the left suprahepatic vein, a voluminous thrombus in the right atrium and an irregular mass in the liver. Alpha-fetoprotein was 77,046 ng/ml The biopsy of the rigth atrium thrombus demonstrated diseminated hepatocellular carcinoma. We comment the patient progress after surgery, the incidence, clinical symptoms, and therapy options for these patients.

IVIg products may be applied for the provision of antibodies in patients with primary or secondary antibody deficiency syndromes or with the aim of immune modulation in patients with autoimmune diseases. The average dose for the provision of antibodies is 400 mg/kg per month while much higher doses are needed 1 to 2 g/kg in a single or in repeated occasions in the treatment of autoimmune diseases e. g. neurological diseases. Indications for treatment have been specified at two consensus meetings (1990 and 1999) and by different groups of experts but off-label use highly exceeds the recommended indications. For this reason risk benefit assessment is of great importance. Adverse events can be categorized as (1) early inflammatory, (2) infectious, (3) rare complications of (mainly) high dose treatment. Early inflammatory reactions are known since the initiation of immunoglobulin treatment, the rate varies greatly 10%-85% and reactions can usually be dealt with by lowering the infusion rate. Viral infections e. g. transmission of viral hepatitis by IVIg have been a problem in certain products until the mid-1990s and industry responded in a fast and efficient manner. Viral safety has been achieved and all IVIg products licensed are considered to be safe in this respect. Rare complications mainly of high dose treatment: renal complications were described already in the mid-1980s they were mainly but not only linked to products containing sucrose, maltose and glucose with or without glycine. These complications are rare (88 patients reported in 30 years) and older patients and patients with conditions predisposing to renal disease were at increased risk. Thromboembolic events were another rare but severe complication of high dose treatment also associated with rapid infusion, deep venous thrombosis, pulmonary embolism, myocardial infarction and stroke have been reported. Possible mechanisms have been discussed.

Since the association between antiphospholipid antibodies and syphilis was first described, many other viral, bacterial and parasitic infections have been shown to induce antiphospholipid antibodies, notably anticardiolipin antibodies. These aPL are usually associated neither with anti-beta2 glycoprotein I antibodies (anti-beta2-GPI) nor with thrombotic events, even if cases of arterial and deep venous thrombosis have been reported in such circumstances. A literature review shows that anticardiolipin antibodies occur frequently in viral infections, particularly in HIV (49.8%), HBV (24%) and HCV (20%). The prevalence of anti-beta2 glycoprotein I antibodies (anti-beta2GPI) is lower (HCV: 1.7%, HIV: 5.6%, HBV: 3.3%) and there is no demonstrated association with a risk of thrombotic events or hematological manifestations defining antiphospholipid syndrome (APS). Regarding other viral infections, including viral hepatitis A, herpes virus (CMV, EBV, VZV), parvovirus B19 and HTLV-1 infections, only a few studies are available but data confirm the high prevalence of antiphospholipid antibodies at the acute phase. Finally, antiphospholipid antibodies, mainly anticardiolipin, are frequently associated with viral infections. Their presence may probably reflect an intense or chronic antigenic stimulation of the immune system. However, their evolution under antiviral therapy and correlation with the quality of the virological control and/or the immune restoration remain to be determined.

Hepatocellular carcinoma is the most common, malignant tumor of liver. Most cases of hepatocellular carcinoma are associated with either viral hepatitis or cirrhosis. But major risk factor for hepatocellular carcinoma in developing countries is mainly chronic hepatitis B. Sorafenib is one of the first-line drug which has been extensively used in metastatic and inoperable hepatocellular carcinoma. We report a rare case of spontaneous deep venous thrombosis of bilateral lower limbs as an important unrecognized side effect of sorafenib.

Acute lymphoblastic leukemia (ALL) in adults is a relatively rare malignancy. The typical presentation includes signs and symptoms associated with bone marrow failure, including fevers, infections, fatigue, and excessive bruising. In this article, we report an unusual systemic presentation of ALL in a previously healthy 18-year-old man. He initially presented with several-day history of nausea and vomiting, 10-pound weight loss, and right upper quadrant abdominal pain with evidence of acute hepatocellular liver injury (elevations in aspartate aminotransferase/alanine aminotransferase) and elevation in serum creatinine. Further history revealed that he just joined the Marine Corp; in preparation, he had been lifting weights and taking protein and creatine supplements. A complete serological evaluation for liver disease was negative and creatine phosphokinase was normal. His aspartate aminotransferase and alanine aminotransferase declined, and he was discharged with expected improvement. However, he returned one week later with continued symptoms and greater elevation of aminotransferases. Liver biopsy was nondiagnostic, revealing scattered portal and lobular inflammatory cells (primarily lymphocytes) felt to be consistent with drug-induced liver injury or viral hepatitis. Given his elevated creatinine, unresponsive to aggressive volume expansion, a kidney biopsy was performed, revealing normal histology. He subsequently developed an extensive left lower extremity deep venous thrombosis. Given his deep venous thrombosis, his peripheral blood was sent for flow cytometry, which revealed lymphoblasts. Bone marrow biopsy revealed 78% blasts with markers consistent with acute B-cell lymphoblastic leukemia. This report emphasizes that right upper quadrant abdominal pain with liver test abnormalities may be the initial presentation of a systemic illness such as ALL.
