Our aim in this study was to compare the depression and anxiety risk in patients with AS and healthy controls and also to determine the relationship between disease activity, quality of life and psychological well-being. Two hundred and forty-three patients with ankylosing spondylitis (AS) and 118 age-, sex- and education-matched healthy controls were enroled into the study. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Functional Index, and Metrology Index, Health Assessment Questionnaire for Spondyloarthropathies (HAQ-S), Hospital Anxiety and Depression Scale (HADS) including depression subscale (HADS-D) and anxiety subscale (HADS-A), Ankylosing Spondylitis Quality of Life (ASQoL) Scale, duration of morning stiffness, pain-visual analogue scale (VAS), patient and physician's global assessment of disease activity (100 mm VAS) were used to assess clinical and psychological status. Patients had similar HADS-D but higher HADS-A than healthy controls. Patients with high risk for depression and anxiety had higher scores in BASDAI, BASFI and also poorer scores in VAS pain, patient global assessment, physician global assessment, HAQ-S and ASQoL. There was a negative correlation of HADS-D and HADS-A scores with educational level of the patients. Higher scores in HADS-D and HADS-A indicated poorer functional outcome and quality of life. Multivariate logistic regression analysis revealed that the HADS-D (OR=6.84), HAQ-S (OR=1.76), VAS pain score (OR=1.03) and ESR (OR=1.02) were independent risk factors for higher anxiety scores whereas HADS-A (OR=1.36) and ASQoL (OR=1.24) were independent risk factors for higher depression scores. The psychological status had close interaction with disease activity and quality of life in patients with AS.

We concluded that the pneumatic compression pump did not contribute to the reduction of lymphedema. In addition, gauging dermal thickness using USG may prove to be a useful measurement method in the evaluation of lymphedema.

JOAS and AOAS had distinctive courses and Turkish patients with AS had similar features compared to other Caucasian patient populations.

Rheumatoid arthritis (RA) is the most common form of inflammatory arthritis, a systemic autoimmune disease characterized by chronic inflammation of the synovial joints, ultimately leading to joint destruction and permanent disability, affecting 1% of the world population. Oxidative stress in rheumatoid inflammation, due to the fact that antioxidant systems are impaired in RA and caused by fee radicals, might have an essential role in etiology of RA. This review includes the interrelation of antioxidants against free radicals in RA patients. There is much evidence that antioxidant team that covers glutathione reductase, catalase, glutathione peroxidase, superoxide dismutase, and glucose-6-phopshate destroy reactive oxygen species and other free radicals through enzymatic as well as nonenzymatic means. The change in relative levels of antioxidants vis-à-vis free radical formation and level could be used as indicators for effective and earlier diagnosis of RA.

Further data pertaining to other countries would be interesting to uncover whether ethnic differences also affect cartilage thickness. Collaborative use of MSUS seems to be promising in this regard.

Osteoporosis has recently been recognized as a major public health problem by some governments and health care providers. Despite significant progress in knowledge about osteoporosis, public awareness is required for effective management if precautions are to be taken. The aim of this study was to evaluate the educational status of osteoporotic individuals, and their awareness about the disease and sources of information. We also aimed to compare the variables between the geographical regions of the country, since significant differences exist in socioeconomic status and lifestyle within the same cultural context. This multicenter study was carried out in eight cities located in six different geographical regions between September 2001 and January 2002. To our knowledge, this is the first multicenter study in Turkey evaluating the relationship between awareness of osteoporotic patients and other variables such as educational level and economic factors. Ten centers took part in this study and consecutive patients with either femoral or lumbar T-scores below -2.5 SD were enrolled into the study group. Bone mineral density was measured using dual energy X-ray absorptiometry (DXA). Patients were interviewed using a questionnaire on past medical history, education, awareness about their disease and risk factors for osteoporosis. A total of 540 women (93.8%) and 36 men (6.3%) were included in the study. Fifty-four percent of patients declared that they were aware of osteoporosis. With regard to sources of information, 56.8% of patients reported physicians as the main source of information. Awareness of the patients was negatively correlated with age (P=0.025, r=-0,94) but positively correlated with education (P=0.0001, r=0.327), level of physical activity (P=0.001, r=143), calcium intake (P=0.005, r=119) and modern clothing style (P=0.0001, r=309). Educational status of the patients was negatively correlated with BMI (P=0.0001, r=-283) and positively correlated with physical activity (P=0.0001, r=268), modern clothing style (P=0.0001, r=600) and smoking (P=0.0001, r=273). Regional comparison of female patients demonstrated that significant differences exist in terms of educational status, clothing style, smoking, level of physical activity, calcium intake, and knowledge about osteoporosis. As a result, education has profound effects on awareness about osteoporosis and many aspects of human behavior, such as calcium intake, physical activity, clothing style and smoking. Significant disparities may be observed between the geographical regions of the same country.

The aim of the present study was to evaluate the effects of different hyaluronic acid forms on synovial fluid nitric oxide (NO) levels and glutathione peroxidase (GSHPx) activities in the treatment of patients with knee osteoarthritis (OA). Forty patients were equally randomized into two groups and treated with native sodium hyaluronate (group I) or with cross-linked hylan G-F 20 (group II). Clinical evaluations and synovial fluid aspirations were performed before the first (baseline), the second (week 1), and third injections (week 2), and a week after the third injection (week 3). NO levels were reduced at the end of the study in both groups (p<0.01 in group I, p=0.001 in group II), while no significant change was found in GSHPx activity. Also, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores and WOMAC physical function scores were gradually improved at all follow-ups in the two groups. No significant differences between the two groups of NO levels, GSHPx activity, WOMAC pain scores, WOMAC stiffness scores, and WOMAC physical function scores were recorded during the study. Intra-articular hyaluronic acid therapy may reduce synovial fluid NO levels. These effects do not seem to be dependent on the molecular weight and various structural changes of hyaluronan products.
