Challenged by the jaw - an interview study on patients' experiences of temporomandibular disorders in rheumatic inflammatory diseases.

Purpose: Rheumatic inflammatory diseases affecting the temporomandibular joint and the masticatory system (TMD) have been described as painful and limiting. However, the condition is often overlooked in primary care. The objective of this qualitative study was to explore and describe TMD-related experiences and perceptions of persons with rheumatic inflammatory disease, and to put this into a rehabilitation perspective.

Effect of respirators equipped with particle or particle-and-gas filters during exposure in a pig confinement building.

Objectives: This study compared the protective effect of two respiratory protection devices during exposure in a pig confinement building.

Methods: Thirty-six healthy persons were exposed for 3 hours in the building, 12 without any protection, 12 with a particle-filter mask, and 12 with a mask filtering both particles and gases. Symptoms, body temperature, nasal lavage fluid, exhaled nitric oxide, and bronchial responsiveness to methacholine were assessed before and after the exposure.
