[Provider delays among patients with breast cancer in a Regional Cancer Care Network: feasibility of personal care schedule].

In order to determine the feasibility of a personal care schedule, we studied provider delays among women with breast cancer in hospitals of a French Regional Cancer Network. In 2001, 148 women have been treated by surgery in the Alexis Vautrin Comprehensive Cancer Centre (AVCCC), then by adjuvant chemotherapy and radiotherapy. Before surgery, individual variations in delays was observed: from 0 to 65 days between the appointment making and the first consultation, from 3 to 108 days to start the treatment.

In-vitro growth patterns of bone marrow erythroid progenitors from patients with post-renal transplant erythrocytosis.

Background: Erythrocytosis is relatively common after renal transplantation and is associated with a higher risk of thromboembolism. Its aetiology is unclear and there is still debate about the most frequently suggested causes. The culture in vitro of erythroid progenitors is regarded as a useful tool for the differential diagnosis of patients with unclear erythrocytosis.

Methodology for using the UMLS as a background knowledge for the description of surgical procedures.

The Unified Medical Language System (UMLS) contains and organizes a large number of terms from a variety of biomedical terminology systems. This study examines the relevance of the UMLS content and structures to the specific purpose of the conceptual representation of medical procedures. The MAOUSSC modelling is a compositional formalism with a description of elementary procedures in terms of elementary concept entities and combinations of such descriptions into more complex ones.
