Fibromyalgia (FM) is a generalized chronic pain condition that is often accompanied by symptoms such as fatigue, sleep disturbances, psychological and cognitive alterations, headache, migraine, variable bowel habits, diffuse abdominal pain, and urinary frequency. Its key assessment domains include pain, fatigue, disturbed sleep, physical and emotional functioning, and patient global satisfaction and health-related quality of life (HRQL). A number of evaluation measures have been adapted from the fields of rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis, and others such as the Fibromyalgia Assessment Status (FAS) index and the Fibromyalgia Impact Questionnaire (FIQ) have been specifically developed. ⋯ The FAS index revealed a statistically significant difference between males and females (p=0.048), analysed using the Mann-Whitney U-test for all pair wise comparisons. The FAS index is a valid three-item instrument (pain, fatigue and sleep disturbances) that performs at least as well as the FIQ in FM patients, and is simpler to administer and score. Both questionnaires may be useful when screening FM patients, with the choice of the most appropriate instrument depending on the setting.

To investigate the variability in cerebral activation according to pain intensity and the association between variability in cerebral activation and clinical features in patients with fibromyalgia syndrome (FMS) using functional magnetic resonance imaging (fMRI). ⋯ This study revealed more distinct signal variability in the ICs in FMS patients than in those of controls in response to high pressure stimuli. The IC can therefore be considered to be a region susceptible to pain perception in FMS patients.

The aim of the present study was to investigate the impact of lifetime potentially traumatic events, including losses, and of post-traumatic stress symptoms on the severity of illness and health-related quality of life in patients with fibromyalgia (FM). ⋯ Our results corroborate the presence of a relationship between the lifetime exposure to potentially traumatic events, in particular loss events, and lifetime post-traumatic stress symptoms and the severity of illness and HRQoL in patients with FM.

Multicenter Study
Patient reported outcomes in ankylosing spondylitis: development and validation of a new questionnaire for functional impairment and quality of life assessment.
To assess validity, reliability and sensitivity to change of a new questionnaire for assessment of functional disability and quality of life in ankylosing spondylitis (AS) patients. ⋯ The CASQ is a reliable and valid tool for assessment of functional impairment and quality of life in AS. The CASQ is well accepted by patients, sensitive to change, easy to administer and score. The CASQ-FI and CASQ-QoL questionnaires can either be used and scored separately to assess for functional disability as well as quality of life or in combination as tools to assess for both parameters.

Comparative Study
A comparison of utility measurement using EQ-5D and SF-6D preference-based generic instruments in patients with rheumatoid arthritis.
The purposes of this study were to analyse and compare aspects of validity (concurrent and discriminant) of the two widely used indirect utility instruments, the EuroQol-5D (EQ-5D) and the Short Form-6D (SF-6D) in a representative cohort of patients with rheumatoid arthritis (RA). ⋯ Although EQ-5D and SF-6D appeared to measure similar constructs, these instruments are quite different from each other in the assessment of RA. For worse health status the median EQ-5D scores were significantly lower than the median SF-6D scores. Moreover, EQ-5D and SF-6D appeared both significantly influenced by disease activity, radiological damage and co-morbidity. For that reason, we advise caution in the employment of these preference-based instruments, especially in RA patients with severe disease.
