Our aim was to investigate the risk of specific cancer types in individuals with dermatomyositis and polymyositis. METHODS We did a pooled analysis of(More)
The objective of this study was to assess the long-term outcome of polymyositis (PM) and dermatomyositis (DM) and the factors predictive of this outcome in a nationwide series in Finland. One hundred and seventy-six patients with PM and 72 patients with DM diagnosed in Finland in 1969–1985 were selected from the national hospital discharge register(More)
OBJECTIVE To study the relationship of polymositis (PM) and dermatomyositis (DM) and cancer in Finland. METHODS The medical records of 175 patients with PM and 71 with DM diagnosed between 1969 and 1985 were reviewed.

The purpose of this study was to evaluate 1/T1rho in relation to 1/T1 and 1/T2 in characterizing normal and diseased muscle. We measured the muscle relaxation rates 1/T1 and 1/T2 at 0.1 T and 1/T1rho at on-resonance locking fields B1 between 10 and 160 microT in myositis patients and normal volunteers. 1/T2 and 1/T1rho of muscle were lower in the patients(More)
