Subacute thyroiditis after COVID-19.

Background: Since the beginning of the pandemic we have learned much about acute organ complications due to COVID-19, but we are still only beginning to understand the post-infection complications.

This is an important differential diagnosis to consider if after a period of improvement, an infected patient develops fever, pain around the region of the thyroid (throat/neck) and/or symptoms of hyperthyroidism.

Psychometric testing of the Norwegian Diabetes Health Profile (DHP-18) in patients with type 1 diabetes.

Fatigue in type 1 diabetes, prevalence, predictors and comparison with the background population.

Aim: Fatigue is scarcely studied in type 1 diabetes (T1D), and the aims were to investigate its prevalence compared to the background population, potential associations, and to validate the Fatigue Questionnaire (FQ) in type 1 diabetes.

Methods: Persons with T1D were recruited from three outpatient clinics in Norway. Fatigue was measured using the FQ, and FQ data from the Norwegian background population were used for comparison.
