Impact of a cancer registry-based genealogy service to support clinical genetics services.

In collaboration with the network of genetics clinics in Scotland, a brief questionnaire was designed to gather data prospectively about the impact of information arising from pedigree research provided by Scottish Cancer Registry personnel. Pedigree research in Scotland is facilitated by access to public records of births, deaths, marriages, and historic census returns up to 1901, and enables the construction of accurate and extensive family pedigrees encompassing generations beyond the detailed knowledge of the proband. Subject to existing confidentiality guidelines, linkage of these pedigrees to cancer registration records results in a more comprehensive family history including the age at diagnosis of any cancer, multiple primary cancers, and cancers unreported from death certificates.

National study of cause-specific mortality in rheumatoid arthritis, juvenile chronic arthritis, and other rheumatic conditions: a 20 year followup study.

Objective: To quantify risks for cause-specific mortality among hospitalized patients with rheumatoid arthritis (RA), juvenile chronic arthritis (JCA), and 4 other rheumatic conditions in a nationwide, population based cohort over a 20 year period.

Methods: All subjects were identified from Scottish hospital inpatient records from 1981 to 2000 and were followed up by computer linkage to the national registry of deaths. Expected mortality was calculated from national mortality rates and was related to the observed incidence by the standardized mortality ratio (SMR) and the corresponding 95% confidence interval (95% CI).
