The effect of several viper venoms on prothrombin Padua.

The effect of four viper venoms (Oxyuranus scutellatus, Notechis scutatus scutatus, Echis carinatus, Naja nigricollis) on prothrombin Padua has been studied. Using Oxyuranus scutellatus venom and Notechis scutatus scutatus venom, prothrombin activity resulted to be moderately decreased similarly to what observed with other one-stage and two-stage methods. On the contrary, using Echis carinatus venom a normal level was obtained. No clotting was observed using the Naja nigricollis venom, regardless of the concentration used. The normal level of factor II obtained with Echis carinatus venom as compared with the low levels obtained with the other venoms, suggests that it acts on a different site of the prothrombin molecule.

Laparoscopic splenectomy in the management of hematological diseases.

The indications for splenectomy in hematological diseases are well known. In particular, they include idiopathic thrombocytopenic purpura (ITP), hereditary spherocytosis (HS) and Hodgkin's disease (HD) (as a part of subdiaphragmatic staging). We present here our initial experience of 10 cases (6 ITP, 2 HS and 2 HD) managed with a laparoscopic approach as opposed to the traditional laparotomy. Advantages over the open operation include decrease of post-operative pain, pulmonary sequelae and infections, cosmetic advantages, faster recovery and reduced hospitalization.

Development of autoimmune thyroid diseases during long-term treatment of hematological malignancies with alpha-interferons.

In recent years recombinant alpha-interferons (alpha-IFNs) have been widely used in the treatment of several hematological malignancies. Prolonged courses of IFN have been shown to induce autoantibodies and to support the exacerbation or even the development of autoimmune diseases. In this report we describe the development of symptomatic autoimmune thyroid diseases in 4 (7.4%) out of 54 patients in chronic treatment with recombinant alpha-IFNs in our department. Two patients developed a disease resembling Hashimoto's thyroiditis after 17 and 49 months of continuous IFN treatment, while the other two developed a typical Graves' disease after 41 and 52 months of therapy. The mechanism by which IFN induces autoimmune thyroid diseases, the choice of searching for anti-thyroid autoantibodies before starting long-term IFN treatment, the option of discontinuing IFN therapy in the presence of overt thyroid diseases, and the management of these diseases are discussed.
