Article Synopsis
  • The study aimed to determine how common rheumatoid arthritis (RA) and spondyloarthritis (SpA) are in Turkey using a phone questionnaire previously tested in other countries.
  • In the research, a Turkish version of the questionnaire was validated with 200 rheumatology patients, then used to survey 4,012 randomly selected individuals to identify potential cases.
  • Results showed a RA prevalence of 0.56% and an SpA prevalence of 0.46% in the general population of Turkey, with significant differences based on region, particularly higher rates in the Northern and Central regions for RA and SpA, respectively.

The aims of this study were to investigate the relationship between magnesium levels and fibromyalgia symptoms and to determine the effect of magnesium citrate treatment on these symptoms. Sixty premenopausal women diagnosed with fibromyalgia according to the ACR criteria and 20 healthy women whose age and weight matched the premenopausal women were evaluated. Pain intensity, pain threshold, the number of tender points, the tender point index, the fibromyalgia impact questionnaire (FIQ), the Beck depression and Beck anxiety scores and patient symptoms were evaluated in all the women.

Objectives: The aim of this study was to develop a Turkish version of the Boston Questionnaire and assess its reliability and validity.

Methods: Sixty-seven patients with idiopathic carpal tunnel syndrome were included in the study. The Turkish version of Boston Questionnaire was obtained after translation process, and was then administered to subjects twice within seven days.

Aim: To investigate the relationship between the major depression and bone mineral density (BMD) in premenopausal women.

Material And Methods: We compared BMD, plasma cortisol level, osteocalcin and C-telopeptide levels of 35 premenopausal women with major depression with those of 30 healthy women who were matched for age and body mass index. Major depression was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders (fourth edition) criteria.

Objectives: The objective of this study was to test whether a Turkish version of the Neck Pain and Disability Scale retains its reliability and validity of the original English version.

Methods: Sixty-one patients with chronic neck pain were enrolled in the study. The Neck Pain and Disability Scale (NPDS), the Pain Disability Index (PDI) and The Hospital Anxiety and Depression Scale (HADS) were filled by all subjects.

Article Synopsis
  • The study investigates the link between body mass index (BMI) and joint space in the knees of female patients with osteoarthritis, aiming to better understand how obesity affects knee health.
  • Fifty-five female osteoarthritis patients participated, with measurements taken of joint space widths and various body composition metrics, including fat and lean mass.
  • Results showed that obese patients (BMI >30) had significantly narrower knee joint spaces compared to non-obese patients, indicating a negative correlation between BMI and joint space width in those with osteoarthritis.

Objective: To examine the possible relationship between chest expansion and pulmonary muscle strength in patients with primary fibromyalgia (PFM).

Methods: Forty-one consecutive women with PFM were compared with age and body mass index matched 40 healthy women concerning pulmonary function tests, chest expansion, and maximum respiratory pressures indicating pulmonary muscle strength, and endurance (MVV). Pain was scored according to a visual analog scale (VAS).

Objective: It has been reported that patients with fibromyalgia syndrome (FMS) have lower maximal respiratory pressures than healthy subjects, indicating reduced pulmonary muscle strength. It has also been reported that patients with FMS have reduced grip strength. In this study, we aimed to examine the possible relationship between handgrip strength as a determinant of peripheral muscle strength and pulmonary muscle strength in patients with FMS by comparing them with healthy controls.

The role of free radicals in fibromyalgia is controversial. In this study, 85 female patients with primary fibromyalgia and 80 age-, height-, and weight-matched healthy women were evaluated for oxidant/antioxidant balance. Malondialdehyde is a toxic metabolite of lipid peroxidation used as a marker of free radical damage.

The aim of the study was to investigate the effect of osteoarthritis on hand function in postmenopausal women. One hundred patients with hand OA and 70 healthy volunteers as controls were evaluated. Grip and pinch strength measurements and Dreiser's functional index were used for hand function.

Behçet's disease is a complex, multisystemic, inflammatory disorder characterized clinically by recurrent oral and genital ulcerations as well as uveitis, sometimes leading to blindness. The etiology and pathogenesis of this syndrome remain obscure. However, various factors are suspected, including genetic propensity, infectious precipitants, and immunological abnormalities.

One of the major groups of chemical mediators involved in the inflammatory response is the prostaglandins, which are synthesized from arachidonic acid by the enzyme cyclooxygenase. The aim of this study is to compare the in vivo effects of celecoxib, meloxicam, and ibuprofen on the activities of catalase (CAT), glutathione peroxidase (GSHPx), superoxide dismutase (SOD) as well as malondialdehyde (MDA), and antioxidant potential levels (AOP) in human erythrocytes. Patients diagnosed as osteoarthritis were included in the study.

Background: It has been shown that patients with thoracic kyphosis due to osteoporosis have diminished pulmonary function. The aim of this study was to determine the pulmonary function, respiratory muscle strength, and endurance of patients with osteoporosis who did not have compression fractures.

Methods: The patient group consisted of 88 recently diagnosed postmenopausal osteoporotic women without spinal fractures.

Cytokine has been postulated to play a role in the pathogenesis of post-menopausal osteoporosis. To test this hypothesis we measured circulating levels of IL-1, IL-6,IL-8 and TNF-alpha in 98 post-menopausal women (30 age matched normal and 68 osteoporotic) with no vertebral fractures. Although the cytokine levels of patients were found in normal cut off values, the difference in cytokine levels between patients and controls was statistically significant for IL-1 and IL-8 (p < 0.

Objective: The association of bone mineral density (BMD) with diffuse idiopathic skeletal hyperostosis (DISH) related to diabetes mellitus was studied.

Methods: We measured BMD and elevated known determinants of BMD (bone markers) in 35 patients with DISH-related type 2 diabetes mellitus, 47 type 2 female diabetics, and 52 female controls with no systemic disease and no drug administration. All subjects were matched for age and body mass index (BMI).

Objective: The prevalence of dermatophytic infections in rheumatoid arthritis is unknown. This study investigated the prevalence of dermatophytosis in patients with rheumatoid arthritis and the relationship between sulfasalazine, low-dose methotrexate and steroid therapy.

Methods: We examined 53 consecutive patients with rheumatoid arthritis for evidence of dermatophytosis and compared them 55 with age- and sex-matched, nonimmunocompromised controls recruited from the low back pain population.

Objective: To assess the relationship of grip strength to site-specific bone mineral density of the metacarpal bone and also axial bone mineral density. The bone mineral density of the lumbar spine, femoral neck and the nondominant hand were measured by DEXA.

Subjects: A total of 187 postmenopausal women were included in the study.

The case of a 36-year old man with Behçet's disease (BS) for 16 years had low back pain and stiffness in the cervical and lumbar spine. He was diagnosed as having ankylosing spondylitis (AS). In this report we wish to emphasize the clinically occult co-existence of AS in BS and revelation of AS after a long time of BS diagnose.
