Assessment of corneal parameters in patients with rheumatoid arthritis.

PURPOSE: To assess the corneal parameters in rheumatoid arthritis (RA) patients. METHODS: We enrolled 64 patients with RA (32 receiving biologic and 32 receiving conventional drugs) and 32 healthy subjects. Keratometric values (anterior flat [K1], steep [K2], and mean keratometry [Km]), corneal thickness from the pupil center (CCT), apex (ACT), and the thinnest point (TCT), and corneal volume (CV) were measured and compared between the groups. RESULTS: K1, K2, and Km values were significantly higher in the RA group (P = 0.013, P = 0.048, P = 0.027, respectively). The means of CCT, ACT, TCT, and CV were significantly lower in RA patients (P < 0.001, P < 0.001, P < 0.001, P = 0.011, respectively). When we divided RA patients into two groups according to the treatment and compared them to controls, the differences in K1, CCT, ACT, TCT and CV were significant (P = 0.030, P = 0.005, P = 0.001, P = 0.001, P = 0.034, respectively). K1 and CV values of RA-biologic group were similar to the control group (P = 0.205 and P = 0.127, respectively). CONCLUSION: Biologic agents contribute to the improvement of K1 and CV values in patients with RA.

Acute effect of kinesiotaping on pain, balance and gait performance in patients with knee osteoarthritis: A randomized controlled study.

BACKGROUND: Kinesiotape application is one of the non-pharmacological methods frequently used in patients with knee OA. Guidelines do not have a consensus on its use in knee osteoarthritis (OA). OBJECTIVE: In this study, we aimed to investigate the acute effect of kinesiotape application on pain, balance, and gait performance in patients with knee OA. METHODS: We included 164 patients with grade 1-3 knee OA according to the Kellgren-Lawrence staging system in the study. Patients were evaluated with visual analog scale (VAS), 10-meter walking test (10MeWT), timed-up and go test (TUG-T), single leg stance test (SLST), and functional reach test (FRT) before and after taping. RESULTS: There was a significant improvement in the post-taping scores of all evaluation parameters in the kinesiotaping group compared with pre-taping scores. Statistically significant improvement was found in all scores of evaluated parameters except FRT scores in the placebo taping group. We found a significant superiority in the mean recovery scores of the kinesiotaping group compared to the placebo-taping group in all parameters except for 10MeWT. CONCLUSIONS: We found significant improvements in both groups. The mean improvement levels in pain and balance scores were better in the KT group than in the PT group.

Hand injuries with mole gun: A hidden danger.

BACKGROUND: Mole guns are handmade destructive tools used in the fight against harmful rodents in agricultural areas. Acciden-tal triggering of these tools at the wrong time can result in major hand injuries that impair hand functionality and cause permanent hand disability. This study aims to draw attention to the fact that mole gun injuries cause severe loss of hand functionality and that these tools should be considered within the scope of firearms. METHODS: Our study is a retrospective, observational cohort study. The demographic characteristics of the patients, the clinical features of the injury, and the surgical methods applied were recorded. The severity of the hand injury was assessed by the Modified Hand Injury Severity Score. The Disabilities of Arm, Shoulder, and Hand Questionnaire was used to evaluate the upper extremity-re-lated disability of the patient. The patients' hand grip strength and palmar and lateral pinch strengths, and functional disability scores were compared with healthy controls. RESULTS: Twenty-two patients with mole gun hand injuries were included in the study. The mean age of the patients was 63.0±16.9 (22-86), and all but one were male. Dominant hand injury was found in more than half of the patients (63.6%). More than half of the patients had major hand injuries (59.1%). The functional disability scores of the patients were significantly higher than the controls, and the grip strengths and palmar pinch strengths were significantly lower. CONCLUSION: Even after years from the injury, our patients had hand disabilities, and their hand strengths were lower than that of the controls. Public awareness should be raised on this issue, and mole guns should be prohibited and considered in the scope of firearms.

Antioxidant profile in patients with complex regional pain syndrome type I.

OBJECTIVE: Complex regional pain syndrome (CRPS) type I is one of the most important problems with regard to physical medicine and rehabilitation. CRPS may cause not only higher therapeutic costs but also greater work time loss. The mechanism and pathogenesis of CRPS still remains unknown. Some findings indicating oxidative stress have been reported. This study was carried out to determine the role of oxidative stress in patients with CRPS. MATERIALS AND METHODS: Twenty patients (13 women and seven men) with CRPS and 20 age- and sex-matched healthy controls were enrolled in this study. Complex regional pain syndrome was diagnosed according to the modified International Association for the Study of Pain (IASP) criteria. We evaluated demographic, clinical and laboratory characteristics of the patients. Antioxidant enzymatic activities consisting of serum superoxide dismutase (SOD), glutathion peroxidase (GPX) and glutathione S-transferase (GST) activities were measured using appropriate methods and compared with healthy controls. RESULTS: The mean age of the patients was 39.5 years and the mean duration of symptoms was 5.5 months. Complex regional pain syndrome devoleped after a traumatic event in 90% of patients. In 10% of patients there were no traumatic events. SOD, GPX and GST levels were significantly higher in patients with CRPS than healthy controls (P = 0.012, P = 0.036 and P = 0.016, respectively). CONCLUSION: Our findings suggest a possible role of oxidative stress in the pathogenesis of CRPS.

Circulating vascular endothelial growth factor concentrations in patients with postmenopausal osteoporosis.

INTRODUCTION: The role of vascular endothelial growth factor (VEGF) in osteoporosis has not yet been clearly established. Vascular endothelial growth factor is an important part of bone formation. In the literature, although the effects of VEGF on bone metabolism were investigated by different studies, there are very rare studies analysing the association between osteoporosis and VEGF. In the present study, our objective was to investigate serum VEGF concentrations in patients with postmenopausal osteoporosis (PMO) and the correlation of serum VEGF levels and bone mineral density (BMD). MATERIAL AND METHODS: This study was performed on 35 PMO patients, and 30 age-matched healthy controls. Serum VEGF concentrations were measured using a quantitative sandwich enzyme immunoassay technique according to the manufacturer's instructions. Bone mineral density values were determined by dual energy X-ray absorptiometry (DEXA). RESULTS: Serum VEGF concentrations were statistically significantly lower in PMO patients than in controls (150 ±65 pg/ml, 260 ±135 pg/ml respectively; p = 0.005). A positive correlation was found between serum VEGF concentrations and BMD values (r = 0.63, p = 0.001). CONCLUSIONS: Vascular endothelial growth factor concentrations were decreased in PMO patients and VEGF may play an important role in bone health.

Melatonin levels in premenopausal women with fibromyalgia syndrome.

The fibromyalgia syndrome (FMS) is a chronic, widespread pain disorder of unknown etiology. It has been suggest that familial component, environmental factors, endocrine and neurotransmitter alterations, and psychological factors may contribute to the development of FMS. The role of melatonin in FMS is unclear. Some studies describe a lower nocturnal peak and a decreased secretion of melatonin in women with FMS when compared with healthy matched controls. The aim of the present study was to determine the possible role of melatonin in FMS patients. We examined the characteristics and levels of melatonin in 25 consecutive premenopausal women with FMS. Serum blood samples were collected from 25 patients and 20 the age and gender matched healthy controls. Melatonin levels were measured by enzyme-linked immunosorbent assay. Then, the results were compared with those from healthy subjects. Serum melatonin levels of FMS patients were not statistically different from those of controls (P > 0.05). No association was observed between melatonin levels of patients with FMS and disease duration, sleep disturbances, fatigue, and pain scores. Our results demonstrate that melatonin levels were similar in patients with FMS and healthy controls. Further studies are needed to determine the possible role of melatonin.

Spastic paraparesis and sensorineural hearing loss in a patient with neurobrucellosis.

OBJECTIVE: Brucellosis is a zoonotic disease and still a major public health problem in many geographic areas including Mediterranean basin and Middle East. Brucellosis causes multisystemic involvement and although rare central nervous system involvement causes serious manifestations. Neurobrucellosis occurs less than 5% of patients and presents with meningitis,encephalitis, myelitis, myelopathy, stroke, paraplegia, radiculoneuritis, intracerebral abscess, epidural abscess, demyelination and cranial nerve involvement or any combination of these manifestations. Spastic paraparesis and the sensorineural involvement are rarely reported in the literature. METHODS: Herein we present a 28 years-old man with spastic paraparesis and sensorineural hearing loss due to neurobrucellosis. RESULTS: The patient was treated with antibiotics combination for 6 months and underwent rehabilitation program. CONCLUSIONS: Neurobrucellosis should be ruled out in patients with unexplained neurological symptoms and/or sensorineuralhearing loss particularly in those living in endemic areas.

Serum melatonin levels in ankylosing spondilitis: correlation with disease activity.

This study was carried out to determine the serum levels of melatonin (MLT) in patients with ankylosing spondilitis (AS) and to evaluate its correlation with disease activity. We assessed clinical characteristics and labaratory parameters. Serum samples from 36 patients (25 males, 11 females) with active AS and 25 healthy subjects (18 males, 7 females) were collected. MLT levels were measured by enzyme-linked immunosorbent assay, and disease activity of AS was assessed according to the Bath AS disease activity index (BASDAI), the erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). Then, the results were compared with those from 25 healty controls. The serum levels of MLT were significantly increased in AS patients as compared to healthy controls (p < 0.05). MLT levels were correlated with BASDAI (r = 0.871, p < 0.001) and CRP levels (r = 0.691, p < 0.001), but not with ESR, in patients with AS. Our results suggest a possible role for this immunoregulatory hormone in the disease activity in AS patients.

Protracted febrile myalgia syndrome in familial Mediterranean fever.

Familial Mediterranean fever (FMF) is an autosomal, recessively inherited multisystem disease that affects various groups of people originating from the Mediterranean Sea region, most specifically those of Jewish, Turkish, Armenian, and Arabic ethnicity. Recurrent attacks of fever and sterile polyserositis of the peritoneum, synovial membranes, and pleura are the main clinical features, although the clinical features of FMF have been expanded in recent years to also include severe myalgia, scrotal swelling, cardiac involvement, and protracted febrile myalgia syndrome (PFMS). PFMS is seen in only a small percentage of FMF patients and is characterized by severe debilitating myalgia of the upper and lower extremities and high fever, occasionally accompanied by abdominal pain, diarrhea, arthritis/arthralgia, and transient vasculitic purpura mimicking Henoch-Schönlein purpura (HSP). Here, we report on a patient with FMF who also presents with PFMS, which is an uncommon and severe manifestation of the disease.
