On pelvic magnetic resonance imaging (MRI), round masses showing peripheral rim enhancement with gadolinium were observed in iliopsoas and iliacus muscles of both inguinal areas. The same lesions were also observed in gluteus(More)

BACKGROUND Although polymorphisms of the catechol-O-methyl transferase (COMT) gene have been implicated in altered pain sensitivity, results concerning the association between COMT gene polymorphisms and fibromyalgia (FM) are equivocal. We assessed the associations between COMT single-nucleotide polymorphisms (SNP) and FM risk and symptom severity. (More)
BACKGROUND Patients with fibromyalgia (FM) exhibit significant clinical heterogeneity, in terms of physical, social and psychological functions, as well as therapeutic responses. Here, we examined FM patients in terms of pain, physical, social and psychological variables to identify clinical subgroups that may be predictive of treatment patterns. METHODS(More)
