The objective of this study is to validate a translated Hebrew version of the FibroFatigue Scale (FFS). The Hebrew version of the FFS was administered to 100 patients fulfilling ACR criteria for classification of FM together with the validated Hebrew version of the Fibromyalgia Impact Questionnaire (FIQ), the validated Hebrew version of the Short Form-36 (SF-36) and a Visual Analogue Scale (VAS) measurement of pain, anxiety, depression, morning stiffness and global well being. Test-retest reliability was assessed using Spearman correlations. ⋯ Internal consistency was 0.89 for the overall FFS. Significant correlations were obtained between the FFS items and the SF-36. These results support the reliability and validity of the data obtained with the Hebrew version of the FSS for detecting and measuring symptom severity in Hebrew speaking patients with FM.

Comparative Study
The effects of bone turnover rate on subchondral trabecular bone structure and cartilage damage in the osteoarthritis rat model.
The effects of bone turnover rate on subchondral trabecular changes and cartilage destruction were evaluated in an iodoacetate-induced osteoarthritis rat model. Thirty female rats were randomly divided into three groups as the ovariectomized group, the no-treatment group and the bisphosphonate medication group. Arthritis was induced by a single intra-articular iodoacetate injection into the right tibiofemoral joint. ⋯ Articular cartilage destruction and severity of arthritis increased significantly in the order: ovariectomized group < no-treatment group < bisphosphonate medication group (p < 0.05). After osteoarthritis development, severities of subchondral trabecular changes appeared to be strongly affected by bone turnover rate. Furthermore, a correlation was found between cartilage destruction severity and subchondral trabecular change in the intra-articular iodoacetate-injected osteoarthritis rat model.
