The purpose of this study is to adapt the Hip disability and Osteoarthritis Outcome Score-Physical function Short-form (HOOS-PS) to Turkish language and to evaluate the psychometric properties of the Turkish version in patients with primary hip osteoarthritis. After the translation from the source language (English) to the target language (Turkish), synthesis, back translation, revision, and pretest stages were done. Next, 50 patients with primary hip osteoarthritis were asked to fill out the Turkish version of the HOOS-PS two times with one week interval. ⋯ Both scores verify that the Turkish HOOS-PS is a reliable tool. Spearman's rank correlation coefficients between the HOOS-PS and overall WOMAC (r = 0.653), WOMAC physical functions (r = 0.626), WOMAC pain (r = 0.629) subscales, overall Lequesne (r = 0.650), and Lequesne daily living activities (r = 0.620) subscales were high (r > 0.6), and moderate correlations were found between the HOOS-PS and WOMAC stiffness (r = 0.511), Lequesne pain (r = 0.569), and Lequesne-walking distance (r = 0.578) subscales (0.6 > r > 0.2), thus providing proof for the validity of the Turkish form. The Turkish HOOS-PS was found to be reliable and valid for patients with primary hip osteoarthritis.

Case Reports
Cryoglobulinemic vasculitis in systemic sclerosis successfully treated with mycophenolate mofetil.
Cryoglobulinemic vasculitis is extremely rare in patients with systemic sclerosis (SSc). So far, only two cases of cryoglobulinemic vasculitis in SSc were described in the literature. This report is about a patient with SSc and secondary Sjőgren's syndrome, who developed typical clinical features of small-vessel vasculitis, including arthritis, purpura, microhaematuria, gangrene of fingers, and toes and myocardial ischemia, in the presence of mixed cryoglobulinemia, ANA, rheumatoid factor, and anti-SSA/Ro antibodies. Symptoms and signs of vasculitis worsened despite initial treatment with corticosteroids and cyclophosphamide, but improved significantly when mycophenolate mofetil was used instead cyclophosphamide.

Multicenter Study
Validation of the 2010 American College of Rheumatology preliminary diagnostic criteria for fibromyalgia in an Iranian population.
The aim of this study was to validate the 2010 American College of Rheumatology (ACR) preliminary criteria for fibromyalgia (FM) in an Iranian population. In this multicenter prospective study, we enrolled 168 FM patients and 110 controls. All participants underwent dolorimetry examination by study assessors and completed a questionnaire containing variables of both the ACR 2010 preliminary and ACR 1990 criteria. ⋯ Optimal test characteristics were achieved for WPI ≥6 and SS scale score ≥4 and improved sensitivity and accuracy of ACR 2010 criteria when compared to expert, 76.1 and 81.7, respectively. The preliminary ACR 2010 criteria performed less desirably in terms of sensitivity in our set of Iranian patients. Selecting lower cutoff points as WPI ≥6 and SS scale score ≥4 improved the diagnostic values of the criteria.

Comparative Study Observational Study
A comparison of impact of fatigue on cognitive, physical, and psychosocial status in patients with fibromyalgia and rheumatoid arthritis.
This study was performed to compare the impact of fatigue on different aspects of quality of life in patients with rheumatoid arthritis (RA) and fibromyalgia syndrome (FM). This study involved subjects with FM (n = 45) and RA (n = 44). Impact of fatigue on physical, cognitive, and psychosocial status was measured with Fatigue Impact Scale (FIS) and health-related quality of life (HRQoL) with the Medical Outcome Study Short Form 36 (SF-36). ⋯ Regarding all the clinical symptoms and disease activity scores, multiple regression models showed that fatigue together with pain affected the HRQoL (SF-36) in both patient groups. Fatigue has different impacts on QoL in FM and RA, respectively. Together with pain, fatigue lead FM patients to see disease as having worse health in terms of mental function, whereas it leads to poor health in terms of physical function in RA.

Prognostic factors of sciatica in the Canon of Avicenna.
Prognosis studies are fast developing and very practical types of medical research. Sciatica is one of the common types of low back pain and identifying prognostic factors of the illness can help physicians and patients to choose best method of practice. The prognostic factors of sciatica are presented from the Canon of Avicenna, one of the most famous physicians in the history of medicine.
