Von Willebrand Factor Multimeric Assay in Acquired von Willebrand Disease Diagnosis: A Report of Experience from North Estonia Medical Centre.

Acquired von Willebrand syndrome (AVWS) is a rare and frequently underdiagnosed bleeding disorder with an unknown prevalence. The diagnosis of AVWS is made based on laboratory investigations and the presence of clinical symptoms. Evaluation and management of affected patients are complex due to the need for multiple laboratory assays.

Sequential population-based studies over 25 years on the incidence and survival of acute de novo leukemias in Estonia and in a well-defined region of western Sweden during 1982-2006: a survey of patients aged ≥65 years.

Estonia regained independence in 1991 after five decades of occupation by the Soviet Union. The present population-based survey was carried out over five consecutive 5-year study periods (1982-2006) on the incidence and survival of de novo acute leukemia patients aged ≥65 years at diagnosis in Estonia and in a well-defined area in western Sweden. During the study period of retrospective work (1982-1996), the first 10 years were carried out while Estonia was still under the mentorship of the Soviet Union.

The incidence and survival of acute de novo leukemias in Estonia and in a well-defined region of western Sweden during 1997-2001: a survey of patients aged 16-64 years.

Background: In a recent retrospective study, we investigated the incidence and survival of de novo acute leukemia (AL) patients aged 16-64 years over three 5-year periods (1982-1996) in Estonia and in the Western Swedish Health Care Region. The incidence rates were similar in the two countries, but the survival data were highly different. Thus, relative survival at 5 years for de novo AL patients in Estonia was virtually negligible, whereas the corresponding figures for the Swedish patients increased from 20.

The incidence and survival of acute de novo leukemias in Estonia and in a well-defined region of western Sweden during 1997-2001: a survey of patients aged >or=65 years.

Background: In a recently published retrospective population-based study over three 5-year periods (1982-1996) we investigated the outcome for de novo acute leukemia (AL) patients aged >or=65 years at diagnosis in Estonia (a country that had been occupied by the Soviet Union over 5 decades) and in the so-called Western Swedish Health Care Region. The age-standardized yearly incidence rates regarding the total number of de novo AL was 5.3/100000 inhabitant for Estonia and 8.

The incidence and survival of acute de novo leukaemias in Estonia and in a well defined region of Western Sweden during 1982-1996: a survey of patients aged 16-64 years.

In the present work the incidence and survival of acute de novo leukaemias in two neighbouring countries, were studied retrospectively over three 5-year periods, 1982-1996. The aim was to compare the above variables, particularly with respect to political/socio-economic and environmental factors, in a well defined area of Sweden, the so-called Western Swedish Health Care Region, with Estonia. Population-wise the Western Swedish Region and Estonia are very similar; area-wise they are also well comparable.
