To investigate the reliability and validity of the Spanish version of the Fibromyalgia Rapid Screening Tool (FiRST), a brief questionnaire for the detection of fibromyalgia (FM) in patients with diffuse chronic pain seen at primary care health centres. ⋯ FiRST questionnaire is a useful tool for the detection of FM in primary care health centres.

Clinical features of primary Sjögren's syndrome (pSS) overlap with those of fibromyalgia (FM). This cross-sectional study was conducted to investigate the prevalence of FM in pSS patients and to compare the clinical features of pSS patients with FM to those without FM. ⋯ Our study showed that FM was prevalent in pSS. FM was associated with higher ESSPRI and more severe depression.

To investigate the reliability and validity of the Spanish version of the 2010 American College of Rheumatology (ACR) Preliminary Diagnostic Criteria for Fibromyalgia (FM) in patients with chronic pain. ⋯ Our results indicate that the 2010 ACR Preliminary Diagnostic Criteria for FM may be useful to establish a diagnosis of FM in Spanish individuals with chronic pain.

Emerging evidence associates chronic pain syndrome, such as fibromyalgia, with endogenous pain modulatory system dysfunction, leading to an impaired descending pain inhibition. In this study, using resting-state functional magnetic resonance imaging (fMRI), we aimed at seeking possible functional connectivity changes of the periaqueductal gray (PAG), a brainstem area that belongs to the endogenous pain modulatory system, in patients with fibromyalgia. ⋯ Our fMRI study showing abnormal resting state functional connectivity of the PAG suggests that patients with fibromyalgia have an endogenous pain modulatory system dysfunction, possibly causing an impaired descending pain inhibition. This abnormal PAG functioning might underlay the chronic pain these patients suffer from.
