[Erythrocyte filterability and relative viscosity in liver cirrhosis and chronic hepatitis].

Fifty patients with liver disease, of whom twenty-four had chronic active hepatitis and twenty-three had liver cirrhosis, were studied and compared with thirty-nine age- and sex-matched controls. Whole blood, plasma and their relative viscosities and the main factors capable of influencing these parameters (Ht, fibrinogen, triglycerides, cholesterol, plasma glucose, total proteins and gamma-globulins) were tested. Whole blood filterability time and velocity of red blood cells (VRBC) were also determined. In ten patients deformability of erythrocytes was determined both in whole blood and in suspensions of RBC in buffer at a Ht of 10%. Whole blood filterability time was significantly increased in all subjects with liver disease. Corrected filterability time was increased only in the cirrhotic group associated with a significant decrease of Ht and fibrinogen and a slight increase in gamma globulins and plasma viscosity. Whole blood viscosity was in the normal range while relative viscosity was decreased in all patients. These findings suggest that both shape alterations of red cells (such as echinocytic shape) and modifications of plasma proteins probably lead to a decrease of red cell filtration in cirrhotic patients.

Myelodysplastic syndrome and thrombocytosis: a random association?

We describe a case characterized by the onset of bone marrow hypoplasia. After treatment with steroid and anabolic compounds, it evolved into a myelodysplastic syndrome (MDS) as demonstrated by morphological and karyotypic analysis. Despite the dysplastic nature of the disorder, a unique feature was its association with a high platelet count. The pathogenesis of the thrombocytosis could not be clearly identified. In fact, the course of the disease was complicated by severe infections that, together with therapy, could have played some role in stimulating thrombopoiesis. However, since MDS can precede or follow a chronic myeloproliferative disease, it is also possible that the platelet elevation in our patient could have been sustained by a primitive thrombocyte disorder.

Primary breast lymphoma.

Breast involvement by non-Hodgkin lymphoma is uncommon. Differences between primary and secondary breast lymphoma have been well-defined. However, histopathological features, therapeutic approach and outcome are still debated. We report the clinical and pathological features of 5 cases of malignant lymphoma primarily involving the breast. The literature is extensively reviewed paying particular attention to pathological features, therapeutic approach and survival analysis. All patients were women; the median age was 63.2 yr. The clinical course was indistinguishable from that of breast carcinoma. High-grade lymphoma was found in 4 cases; T cell lineage antigens were expressed in one case. All patients were in stage I or II. Treatment consisted of chemotherapy and/or radiotherapy. The follow-up period ranged from 20 to 54 months (mean, 33.2). All patients are still in complete clinical remission. Analysis of the literature showed that about 80% of cases are high grade lymphoma. In this group, stage I at presentation statistically gives the best survival rate; surgery does not appear to have a role in high-grade lymphoma treatment.
