[Muscle problems due to statins: underestimated].

Statin-associated muscle problems are more common than the 1-5% prevalence reported in large clinical trials. Observational studies show a prevalence of about 10%. Muscle problems can occur anytime during statin treatment, but usually occur in the first 6 months.

Giant cell arteritis: heterogeneity in clinical presentation and imaging results.

Objective: Giant cell arteritis (GCA) is commonly known for its clinical presentation of temporal arteritis. However, GCA affects large arteries, predominantly the aorta and its proximal branches, in up to 75% of cases. We describe the clinical presentation and diagnostic test results of patients with large-vessel GCA.
