Genetic and environmental factors are thought to play roles in the etiopathology of fibromyalgia syndrome (FMS). The objective of this study was to determine the potential effects of single nucleotide polymorphisms (SNPs) in catechol-O-methyltransferase (COMT) (rs4680) and 5-hydroxytryptamine (serotonin) 2A (5-HT2A) receptor (rs6313 and rs6311) genes on susceptibility to FMS. One hundred seventy-one women (80 FMS, 91 control) were enrolled in the study. ⋯ Beck depression inventory, state and trait anxiety inventory and symptom checklist-90 revised (SCL-90-R) tests were applied to both patients and controls. There were no observed differences in the frequencies of alleles and genotypes between patients and controls for the COMT, and the two 5-HT2A receptor gene polymorphisms (P>0.05). Our results suggest that the investigated polymorphisms seem not to be the susceptibility factors in etiology of FMS.

To analyze coping styles of fibromyalgia (FM) patients with specific emphasis on differences in coping styles between fibromyalgia patients with and without post traumatic stress disorder (PTSD). Seventy-seven consecutive patients (40 women and 37 men) who fulfilled ACR criteria for FM, and 48 healthy controls, completed questionnaires measuring prevalence and severity of PTSD symptoms, including the structured clinical interview for DSM-III-R-non-patient edition (SCID-NP) and the clinician administered PTSD scale (CAPS). Subjects were divided into two groups based on the presence or absence of PTSD symptoms. ⋯ Our results have delineated coping patterns of FM patients, identifying suppression, help-seeking, replacement, substitution and replacement as strategies more common among these patients. We further identified suppression as the only coping style significantly more common among FM patients with co-morbid PTSD then among FM patients without such a diagnosis. Our results may serve to further characterize cognitive and behavioral aspects of FM patients and subsequently guide therapeutic interventions.

The aim of this study is to assess the reliability and validity of the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) in Moroccan patients with knee osteoarthritis. The WOMAC was translated and back translated to and from dialectal Arabic, pre-tested and reviewed by a committee following the Guillemin criteria. The Moroccan version of the WOMAC was administered twice during a 24-48 h interval to 71 Moroccan patients with symptomatic knee osteoarthritis, fulfilling the revised criteria of the American College of Rheumatology. ⋯ Correlation between VAS handicap (rho=0.38 P<0.001) and maximum distance walked (rho=-0.40, P<0.01) was observed with physical function subscale. There was no correlation between age, duration of disease, BMI and severity of pain and physical function in knee OA. The Moroccan version of the WOMAC is a comprehensible, reliable, and valid instrument to measure outcome in patients with knee OA.
