Assessment of hand function and disability in fibromyalgia.

OBJECTIVE: Fibromyalgia, a potentially debilitating chronic pain syndrome, is a chronic disease. We aimed to compare the hand function of fibromyalgia (FM) patients and healthy individuals and to demonstrate the relationship between hand disability and FM. PATIENTS AND METHODS: The study was consisted of 40 female patients with FM and 30 healthy controls. All participants were evaluated for pain threshold measurements, handgrip strength, and pinch strength. Functional states, hand disability, and hand skills and coordination were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) form, the Disability of Arm-Shoulder-Hand (DASH) questionnaire and the Purdue Pegboard Test, respectively. RESULTS: Handgrip strength values, DASH score, lateral pinch strength test, Pegboard placement time, and Pegboard collection time of the patient group were significantly lower than those of the control group (all p < 0.05). A negative correlation was found between FIQ score and handgrip strength, two-point pinch strength test, three-point pinch strength test, and lateral pinch strength test in patients with moderate FM (all p < 0.05). Furthermore, a correlation was observed between DASH score and handgrip strength, lateral pinch strength test, Purdue Pegboard placement time, and Purdue Pegboard collection time in patients with moderate FM (all p < 0.05). CONCLUSIONS: Our results show that hand function was decreased in patients with FM compared to healthy controls and decreasing hand function was influenced by FIQ score. As a result, the evaluation of hand function should be taken into consideration in the management of FM.

The effect of gadolinium-based contrast agents on rat testis.

Previous studies have reported that repeated administrations of linear gadolinium-based contrast agents lead to their accumulation in the brain and other tissues in individuals with normal renal functions. The purpose of this prospective animal study was to investigate the effect of multiple administrations of macrocyclic ionic (gadoteric acid) and linear nonionic (gadodiamide) gadolinium-based contrast agents (GBCAs) on rat testis tissue and to compare these molecules in terms of tissue damage. Thirty-two male Sprague-Dawley rats were kept without drugs for 5 weeks after administration of 0.1 mmol mg-1 kg-1 (0.2 ml/kg) gadodiamide and gadoteric acid for 4 days over 5 weeks. Biochemical, histopathological and immunohistochemical changes in testis tissue were evaluated at the end of 10 weeks. When used in repeated clinical doses, gadolinium was observed to increase apoptosis in the Leydig cells of the rat testis, and to increase serum Ca+2 levels and reduce testosterone levels (p < .05). Although the difference was not statistically significant, a greater loss of spermatozoa and immature germinal cell accumulation were observed in the seminiferous tubule lumen in the GBCA groups compared with the control and saline groups (p > .05). Both linear and macrocyclic contrast agents have toxic effects on testis tissue, irrespective of the type of drug.

Squamous cell carcinoma arising from teratoma of the ovary: magnetic resonance, computed tomography, and pathological findings.

In the present case report, the authors investigated the clinicopathological characteristics of squamous cell carcinoma (SCC) arising from teratoma of the ovary and intended to report their clinical experience. Malignant transformation of ovarian teratoma is a quite rare condition with SCC observed to be the most common form of transformation. The present case was a 43-year-old female patient and her clinical presentation was abdominal pain, abdominal distension, and abdominal mass sensation. The patient underwent ultrasonography. After detection of a mass, magnetic resonance imaging (MRI) was performed. Surgery was performed on the patient and the pathological report revealed SCC arising from teratoma. The patient was evaluated retrospectively in terms of demographic characteristics, MRI, surgical findings, and prognosis.

Medial olivocochlear reflex in ankylosing spondylitis patients.

OBJECTIVE: Ankylosing spondylitis (AS) is a chronic systemic inflammatory disease. Via autoimmune mediators, AS can damage the auditory system similar to other systems. Otoacoustic emission studies in AS patients showed that the damage that causes hearing loss was in the outer hair cells. The medial olivocochlear (MOC) reflex is used to evaluate the MOC efferent system (MOES), which includes the outer hair cells. The aim of this study was to evaluate the presence of subclinical damage in the inner ear with the aid of the MOC reflex test in AS patients with no hearing complaints. PATIENTS AND METHODS: Thirty-four patients with AS and a control group of 30 healthy volunteers with similar demographic characteristics were evaluated in the study. Otoacoustic emission responses, MOC reflex results, and frequency-specific and total suppression findings were compared between the groups. The relationship between clinical and laboratory findings for the AS patients, and the MOC reflex data were also investigated. RESULTS: Reduced MOC reflex response (p = 0.04) and suppression (p = 0.019) were detected in AS patients. When the clinical and laboratory findings for the AS patients and the MOC reflex test results were compared, a significant correlation was found only between the MOC reflex and the erythrocyte sedimentation rate. CONCLUSION: The results showed that AS can damage the inner ear, especially the MOES, and can reduce the MOC reflex response without clinical hearing loss.

Relationship of osteoprotegerin to pulse wave velocity and carotid intima-media thickness in rheumatoid arthritis patients.

OBJECTIVE: Osteoprotegerin (OPG) is considered an important biomarker in cardiovascular (CV) disease. CV disease is the most common cause of mortality in patients with rheumatoid arthritis (RA), a consequence of accelerated atherosclerosis. The present study aimed to evaluate the relationship of serum OPG levels to arterial stiffness, carotid intima-media thickness (CIMT), and clinical and laboratory indices in RA patients. PATIENTS AND METHODS: Included in the study were 68 RA patients with no history or signs of CV disease and 48 healthy subjects Disease activity was assessed by the 28-joint disease activity score (DAS28) in RA patients. Serum OPG level was measured using enzyme-linked immunosorbent assay (ELISA). Carotid femoral pulse wave velocity (PWV) was measured as an index of arterial stiffness and CIMT was evaluated by carotid ultrasonography. RESULTS: The mean serum OPG level was significantly higher in RA patients than controls (p < 0.001). Mean PWV and CIMT were also significantly increased in RA patients compared to controls (both p < 0.001). In RA patients, serum OPG level was significantly correlated with PWV and CIMT, as well as rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibody; but not with DAS28, high-sensitivity C-reactive protein (hsCRP), or erythrocyte sedimentation rate. CONCLUSION: Serum OPG levels were increased and correlated with CIMT and PWV in RA patients. In addition to PWV and CIMT, OPG may be a useful biomarker for CV risk management in RA patients.

Endovenous laser ablation treatment with 980 nm diode laser for saphenous vein insufficiency: 6 months follow up results.

OBJECTIVE: Superficial venous insufficiency is a common problem associated with varicose veins which, if untreated, may progress to venous ulceration. Endovenous laser ablation (EVLA) is a new, minimally invasive method for management of superficial venous insufficiency and varicose veins. The aim of this study was to demonstrate the effectiveness of 980 nm EVLA for treatment of symptomatic saphenous venous insufficiency and to present its early outcomes. METHODS: Thirty-eight great saphenous veins and 5 small saphenous veins in 40 patients with saphenofemoral reflux were treated with 980 nm diode endovenous laser equipment. The diameter and length of the vein treated, total laser energy and energy density (Joules/cm) delivered were recorded. To determine the severity of the venous disease Venous Clinical Severity Score (VCSS) and Visual Analogue Scale (VAS) were used. Patients were followed up for 6 months after the procedure. Complications were recorded prospectively. RESULTS: Forty-three saphenous veins in 40 patients were treated. The mean age of the patients was 39.9 (range 21-72) years. The mean diameter and length of the veins were 4.9 mm (range, 3.5 to 8.5 mm) and 30.2 cm (range, 16 to 50 cm), respectively. At 6 months follow-up, total occlusion rate was 95.4% (41/43), and recanalization rate was 4.6%. Significant decrease was observed for VCSS and VAS scores after the procedure. No major complication was detected. CONCLUSION: EVLA treatment for superficial venous insufficiency is safe and can be carried out under local anaesthesia in an outpatient setting with good patient satisfaction and low complication rates.
