Sero-epidemiological survey for alveolar echinococcosis (by Em2-ELISA) of blood donors in an endemic area of Switzerland.

Sera from 17,166 blood donors living in 10 cantons of northern Switzerland in an area endemic for Echinococcus multilocularis were investigated by serological survey for alveolar echinococcosis (AE). A highly species-specific antigen (Em2) and a commonly used E. granulosus hydatid fluid antigen (EgHF) were compared for their suitability in seroepidemiology. EgHF showed a degree of nonspecificity which did not allow direct detection of AE cases. Antibody reaction with Em2 resulted in the detection of 2 asymptomatic clinical cases of AE (seroprevalence 0.01%) within this population of blood donors. A further 4 persons were positive in Em2-ELISA. These 4 persons had negative imaging studies and will be followed serologically and clinically.

[Prognostic factors of survival and tumor recurrence following surgery and radiotherapy for breast cancer with positive axillary nodes. La Chaux-de-Fonds, 1968-1975].

Survival and treatment failure are analyzed in a homogeneous group of 70 pre- or post-menopausal patients with operable breast cancer and histologically involved axillary nodes. From March 1968 to December 1975, all patients underwent simple or radical mastectomy, followed by radiotherapy in 67. The period of observation varied from 11 months to 10 years. Treatment failures were observed on 34 patients: 10 loco-regional relapses, 21 distant metastatizations, and 3 tumors in the other breast. Analysis of actuarial survival curves shows a statistically significant difference between patients with 1 to 3 positive axillary nodes and patients with 4 or more, but no difference with regard to the volume of the tumor and the patient's age. Comparison of disease-free period curves shows statistically significant differences between patients aged below and over 55 years, tumor of less or more than 2 cm, and 4 or fewer axillary nodes. These results are comparable to those in the literature and form a contribution to a Swiss study of post-operative adjuvant chemotherapy in breast cancer with positive axillary nodes.

[Integrating the blood transfusion service into hospital activities].

The traditional and present activities of a regional transfusion center catering for the blood product requirements of a population of some 250 000 are reviewed. It is suggested that the work of a blood bank should be extended to the laboratory sector and cover immunohematology, hematology and coagulation. Through the laboratory the transfusion center would thus be in close liaison with hospital clinical departments. It is of advantage for the staff of the enlarged blood bank to perform some degree of clinical activity, to facilitate discussion of clinical and technical problems relating to hematological disorders in general.
