Clinical properties and rehabilitation needs of earthquake survivors in a subacute rehabilitation setting.

BACKGROUND: This descriptive analysis examines the victims of the February 6, 2023, earthquakes in Kahramanmaras and Elbistan, Türkiye. It aims to detail the injury profiles related to neuro-musculoskeletal trauma, assess the rehabilitation needs of patients, and propose a comprehensive rehabilitation approach. METHODS: The study included patients injured in the Kahramanmaras-centered earthquake on February 6, 2023, who were transported to our hospital based on their rehabilitation needs. Data from patients treated at our hospital were recorded retrospectively. This included demographic information, accompanying pathologies, laboratory findings, rehabilitation programs, and treatments received during their hospital stay. Statistical analyses were conducted to examine the data. RESULTS: A total of 141 patients with musculoskeletal injuries were admitted due to injuries sustained from the earthquake. The mean age of the participants was 39.76 years, with a slight female predominance (56.7%). The majority of patients sustained injuries while trapped under debris (90.1%), with an average duration of 10 hours under rubble. Fractures were the most common form of injury (53.2%), predominantly affecting the lower extremities. Peripheral nerve injuries were present in 41.1% of patients, and amputations were observed in 30.5%. Complications included compartment syndrome (46.1%), crush syndrome (36.2%), and various infections. Pain was prevalent among patients, with somatic pain being the most reported type. Individualized rehabilitation programs were implemented, incorporating physical therapy, wound care, pain management, and psychosocial support. CONCLUSION: This study highlights the critical rehabilitation needs of earthquake survivors and emphasizes the importance of early and comprehensive rehabilitation interventions. Multidisciplinary rehabilitation programs were crucial in addressing medical issues, functional limitations, and psychological challenges faced by the survivors. The findings contribute to a deeper understanding of earthquake-related injuries and underscore the significance of well-coordinated rehabilitation strategies in disaster responses.

Comparison of the short-term effects of the conventional motorized traction with non-surgical spinal decompression performed with a DRX9000 device on pain, functionality, depression, and quality of life in patients with low back pain associated with lumbar disc herniation: A single-blind randomized-controlled trial.

OBJECTIVES: This study aims to compare the efficiency of conventional motorized traction (CMT) with non-surgical spinal decompression (NSD) using the DRX9000™ device in patients with low back pain associated with lumbar disc herniation (LDH). PATIENTS AND METHODS: Between March 2009 and September 2009, a total of 48 patients (29 females, 19 males; mean age 43.1±9.8 years; range, 18 to 65 years) were randomized into two groups. The first group (n=24) underwent CMT and the second group (n=24) underwent NSD for a total of 20 sessions over six weeks. The patients were evaluated before and after the treatment. Pain was assessed using the Visual Analog Scale (VAS), functional status using the Oswestry Disability Index (ODI), quality of life using the Short Form-36 (SF-36), state of depression mood using the Beck Depression Inventory (BDI), and the global assessment of the illness using the Patient's Global Assessment of Response to Therapy (PGART) and Investigator's Global Assessment of Response to Therapy (IGART) scales. RESULTS: There was no significant difference in the evaluation outcomes before the treatment between the groups. However, a statistically significant decline was found in the VAS, ODI, and BDI scores after the treatment in both groups (all p<0.001). Except for two subgroups, no significant changes were observed in the SF-36 form. Assessment of "marked improvement" was globally most frequently reported one in both groups. No significant difference was observed in the evaluation outcomes after treatment between the groups. CONCLUSION: Our study results show that both CMT and NSD are effective methods in pain management and functional status and depressive mood improvement in patients with LDH, and NSD is not superior to CMT in terms of pain, functionality, depression and quality of life.

A comparison of the effects of exercises plus connective tissue massage to exercises alone in women with fibromyalgia syndrome: a randomized controlled trial.

This study aimed to compare the effectiveness of a 6-week combined exercise program with and without connective tissue massage (CTM) on pain, fatigue, sleep problem, health status, and quality of life in patients with fibromyalgia syndrome (FMS). Patients were randomly allocated into Exercise (n = 20) and Exercise + CTM (n = 20) groups. The exercise program with and without CTM was carried out 2 days a week for 6 weeks. Pain, fatigue, sleep problem with Visual Analog Scales, health status with Fibromyalgia Impact Questionnaire (FIQ), and quality of life with Short Form-36 were evaluated. After the program, pain, fatigue and sleep problem reduced, health status (except of the scores of FIQ-1 and FIQ-10), physical functioning, role limitations due to physical health, bodily pain, role limitations due to emotional health, vitality, and general health perceptions parameters related to quality of life improved in the Exercise group, (P < 0.05). In the Exercise + CTM group, pain, fatigue and sleep problem decreased, health status and quality of life improved (P < 0.05). Pain, fatigue, sleep problem, and role limitations due to physical health improved in the Exercise + CTM group in comparison to the Exercise group (P < 0.05). The study suggested that exercises with and without CTM might be effective for decreasing pain, fatigue and sleep problem whereas increasing health status and quality of life in patients with FMS. However, exercises with CTM might be superior in improving pain, fatigue, sleep problem, and role limitations due to physical health compared to exercise alone.

Ultrasonographic Evaluation of Acupuncture Effect on Common Extensor Tendon Thickness in Patients with Lateral Epicondylitis: A Randomized Controlled Study.

OBJECTIVE: To explore the effect of acupuncture on common extensor tendon (CET) thickness in patients with lateral epicondylitis (LE). Additionally, to identify whether clinical and ultrasonographic changes showed any correlation. METHODS: Forty-one patients were randomly assigned to acupuncture and control groups. Conventional treatment (rest, NSAII, bracing, exercise) methods for LE were applied to all patients. In addition to this, the acupuncture treatment was applied to the acupuncture group. The visual analog scale (VAS) for pain, the Duruoz Hand Index (DHI) for functioning of the affected limb, the pressure pain threshold, and CET thickness (via ultrasound imaging) were assessed before and end of the treatment in both groups. RESULTS: The VAS and DHI scores in both groups decreased. The pressure pain threshold and CET thickness only demonstrated improvement in the acupuncture group. CONCLUSION: These findings show that the CET thickness was reduced after 10 sessions of acupuncture treatment in LE patients.

The effects of acupuncture versus sham acupuncture in the treatment of fibromyalgia: a randomized controlled clinical trial.

OBJECTIVE: The aim of this manuscript is to determine and to compare the efficacy of real acupuncture with sham acupuncture on fibromyalgia (FM) treatment. METHODS: 50 women with FM were randomized into 2 groups to receive either true acupuncture or sham acupuncture. Subjects were evaluated with VAS (at night, at rest, during activity), SF-36, Fibromyalgia Impact Questionnaire (FIQ), Beck Depression scale (BDI), Fatigue Severity Scale (FSS) at baseline, 1 month and 2 months after the 1st session. Patients in both groups received 3 sessions in the 1st week, 2 sessions/week during 2 weeks and 1 session/week in the following 5 weeks (totally 12 sessions). RESULTS: 25 subjects with a mean age of 47,28±7,86 years were enrolled in true acupuncture group and 25 subjects with a mean age of 43,60±8,18 years were enrolled in sham acupuncture group. Both groups improved significantly in all parameters 1 month after the 1st session and this improvement persisted 2 months after the 1st session (p<0,05). However, real acupuncture group had better scores than sham acupuncture score in terms of all VAS scores, BDI and FIQ scores either 1 or 2 months after the 1st session (all p<0,05). CONCLUSION: Acupuncture significantly improved pain and symptoms of FM. Although sham effect was important, real acupuncture treatment seems to be effective in treatment of FM.

An Unusual Cause of Myelopathy: Ochronotic Spondyloarthropathy With Positive HLA B27.

Ochronosis is a late developing complication of alkaptonuria, a black brownish pigment in the fibrous and cartilaginous tissues. Although most previous studies reported alkaptonuria and back pain due to ochronosis, thoracic myelopathy is an extremely rare complication. In this report, a paraparetic patient who has ochronotic spondiloarthropathy with the presence of HLA B27 antigen is described. He had low back and leg pain and morning stiffness for 5 yrs. Last year, these were followed by tingling, numbness, and weakness the in lower extremities and he was operated on with preliminary diagnosis of prolapsed disc herniation and cord compression. Surgery is suggested for disc herniations related to ochronotic spondyloarthropathy if it is necessary or neurologic symptoms are present. However, his pain and weakness have partially recovered after the operation. After medical and physical treatment, he showed clinically significant improvements. This case report demonstrates that the management of ochronosis needs a multidisciplinary approach with physiologic, neurologic, and psychologic effects and proper treatment may significantly improve functional outcomes in these patients.

Dynamic Thiol/Disulphide Homeostasis in Patients With Fibromyalgia.

OBJECTIVES: This study aims to investigate dynamic thiol/disulphide homeostasis in patients with fibromyalgia syndrome (FMS). PATIENTS AND METHODS: Fifty female patients with FMS (mean age 40.5±7.2 years; range 21 to 55 years) and 40 healthy female controls (mean age 39±9.4 years, range 22 to 55 years) were included in the study. Pain visual analog scale, tender points, Fibromyalgia Impact Questionnaire, and Beck Depression Inventory were evaluated. Age, body mass index (BMI), and symptom durations were also recorded. Native thiol, disulphide and total thiol levels were measured with a novel automated method. RESULTS: Serum disulphide levels were 14.7±3.4 µmol/L and 22.2±3.6 µmol/L in the FMS and control groups, respectively (p<0.001). Native thiol levels were 452.1±33.8 µmol/L and 433.5±37.6 µmol/L in the FMS and control groups, (p=0.015), while total thiol levels were 481.7±35.6 µmol/L and 477.5±38.9 µmol/L in the FMS and control groups, respectively (p=0.593). In the FMS group, disulphide/native thiol percent ratios and disulphide/ total thiol percent ratios were statistically significantly lower and native/total thiol percent ratios were statistically significantly higher than those of the control group. There were no correlations between serum thiol/disulphide profiles and pain scores & clinical variables in patients with FMS. CONCLUSION: Because of the decreased disulphide and increased native thiol levels, the thiol/disulphide balance has shifted to the reductive side. This metabolic disturbance may have a role in the pathogenesis of FMS.

The prevalence and risk factors for osteoporosis among 18- to 49-year-old Turkish women.

The aim of this study was to determine the prevalence of osteoporosis and associated risk factors in Turkish women aged 18-49 years. A population-based, cross-sectional study was conducted between January and April 2014. The sample (n = 1,792) was comprised of women aged 18-49 years, who resided in Cubuk, Ankara, Turkey, and were selected by simple random sampling. The data were collected in face-to-face interviews using an Individual Information Form and an Osteoporosis Risk Estimation Scale. Bone mineral density was assessed using standard dual-energy X-ray absorptiometry. Multiple logistic regression and chi-square analyses were used for analyses. Most participants (80.1%) were at low risk of developing osteoporosis, while 6.9% were at medium to high risk of developing the disease. From bone mineral density levels, 33.3% were osteopenic; 4.0% were osteoporotic; 33.3% were osteopenic at the femoral neck; and 6.7% were osteoporotic at the lumbar vertebra L1-L4. Further, results of multiple logistic regression analyses showed that osteoporosis risk was significantly associated with smoking, having light skin, multiparity, and having a family history of osteoporosis (p < .05). These results indicated that public health screening strategies for protecting women's bone health at earlier ages than previously thought might be beneficial.

Physiological parameters as a tool in the diagnosis of fibromyalgia syndrome in females: A preliminary study.

AIMS: Although fibromyalgia (FM) syndrome is associated with many symptoms, there is as yet no specific finding or laboratory test diagnostic of this syndrome. The physical examination and laboratory tests may be helpful in figuring out this syndrome. MATERIALS AND METHODS: The heart rate, respiration rate, body temperature (TEMP), height, body weight, hemoglobin level, erythrocyte sedimentation rate, white blood cell count, platelet count (PLT), rheumatoid factor and C-reactive protein levels and electrocardiograms (ECG) of FM patients were compared with those of control individuals. In addition, the predictive value of these tests was evaluated via receiver operating characteristic (ROC) analysis. KEY FINDINGS: The results showed that the TEMP and the PLT were higher in the FM group compared with the control group. Also, ST heights in ECGs which corresponds to a period of ventricle systolic depolarization, showed evidence of a difference between the FM and the control groups. There was no difference observed in terms of the other parameters. According to the ROC analysis, PLT, TEMP and ST height have predictive capacities in FM. SIGNIFICANCE: Changes in hormonal factors, peripheral blood circulation, autonomous system activity disorders, inflammatory incidents, etc., may explain the increased TEMP in the FM patients. The high PLT level may signify a thromboproliferation or a possible compensation caused by a PLT functional disorder. ST depression in FM patients may interrelate with coronary pathology. Elucidating the pathophysiology underlying the increases in TEMP and PLT and the decreases in ST height may help to explain the etiology of FM.

Isokinetic muscle performance of the hip and ankle muscles in women with fibromyalgia.

OBJECTIVE: To compare isokinetic muscle performances of a proximal (hip) and a distal (ankle) muscle of fibromyalgia syndrome (FMS) patients with those of age- and body mass index (BMI)-matched healthy subjects. METHODS: Thirty female patients with FMS (mean age: 41.5 ± 6.7 years [range, 27-54]) and 30 age- (mean age: 40.6 ± 6.0 years [range, 27-54]) and BMI-matched female healthy controls were consecutively enrolled. Demographic and clinical characteristics of the subjects were recorded. Isokinetic measurements of hip and ankle flexion and extension at angular velocities of 60°/s and 180°/s, peak torques, flexor-extensor torque ratios, muscle fatigue resistance values and average power were obtained. RESULTS: Mean disease duration of FMS patients was 2.4 ± 1.9 years. Mean weight, height and BMI values were 70.4 ± 12.5 kg, 159.5 ± 6.0 cm and 27.7 ± 4.7 kg/m² (FMS patients) and 69.3 ± 10.1 kg, 161.7 ± 6.2 cm and 26.6 ± 4.3 kg/m² (control subjects), respectively (all P > 0.05). All isokinetic values were statistically decreased in the FMS group when compared with the control group, except for the peak torques at angular velocity of 180°/s on flexion of the hip and extension of the ankle and the total work and average power on extension of the ankle. We did not find any correlation between isokinetic values and disease related parameters of FMS patients. CONCLUSIONS: In the light of our results, we may conclude that muscle strength and muscle fatigue seem to decrease in FMS patients' both proximal and distal lower extremity muscles.

A Study on the Effects of Sympathetic Skin Response Parameters in Diagnosis of Fibromyalgia Using Artificial Neural Networks.

Fibromyalgia syndrome (FMS), usually observed commonly in females over age 30, is a rheumatic disease accompanied by extensive chronic pain. In the diagnosis of the disease non-objective psychological tests and physiological tests and laboratory test results are evaluated and clinical experiences stand out. However, these tests are insufficient in differentiating FMS with similar diseases that demonstrate symptoms of extensive pain. Thus, objective tests that would help the diagnosis are needed. This study analyzes the effect of sympathetic skin response (SSR) parameters on the auxiliary tests used in FMS diagnosis, the laboratory tests and physiological tests. The study was conducted in Suleyman Demirel University, Faculty of Medicine, Physical Medicine and Rehabilitation Clinic in Turkey with 60 patients diagnosed with FMS for the first time and a control group of 30 healthy individuals. In the study all participants underwent laboratory tests (blood tests), certain physiological tests (pulsation, skin temperature, respiration) and SSR measurements. The test data and SSR parameters obtained were classified using artificial neural network (ANN). Finally, in the ANN framework, where only laboratory and physiological test results were used as input, a simulation result of 96.51 % was obtained, which demonstrated diagnostic accuracy. This data, with the addition of SSR parameter values obtained increased to 97.67 %. This result including SSR parameters - meaning a higher diagnostic accuracy - demonstrated that SSR could be a new auxillary diagnostic method that could be used in the diagnosis of FMS.

Investigation of the relationship between anxiety and heart rate variability in fibromyalgia: A new quantitative approach to evaluate anxiety level in fibromyalgia syndrome.

BACKGROUND: Fibromyalgia syndrome (FMS) is identified by widespread musculoskeletal pain, sleep disturbance, nonrestorative sleep, fatigue, morning stiffness and anxiety. Anxiety is very common in Fibromyalgia and generally leads to a misdiagnosis. Self-rated Beck Anxiety Inventory (BAI) and doctor-rated Hamilton Anxiety Inventory (HAM-A) are frequently used by specialists to determine anxiety that accompanies fibromyalgia. However, these semi-quantitative anxiety tests are still subjective as the tests are scored using doctor-rated or self-rated scales. METHOD: In this study, we investigated the relationship between heart rate variability (HRV) frequency subbands and anxiety tests. The study was conducted with 56 FMS patients and 34 healthy controls. BAI and HAM-A test scores were determined for each participant. ECG signals were then recruited and 71 HRV subbands were obtained from these ECG signals using Wavelet Packet Transform (WPT). The subbands and anxiety tests scores were analyzed and compared using multilayer perceptron neural networks (MLPNN). RESULTS: The results show that a HRV high frequency (HF) subband in the range of 0.15235Hz to 0.40235Hz, is correlated with BAI scores and another HRV HF subband, frequency range of 0.15235Hz to 0.28907Hz is correlated with HAM-A scores. The overall accuracy is 91.11% for HAM-A and 90% for BAI with MLPNN analysis. CONCLUSION: Doctor-rated or self-rated anxiety tests should be supported with quantitative and more objective methods. Our results show that the HRV parameters will be able to support the anxiety tests in the clinical evaluation of fibromyalgia. In other words, HRV parameters can potentially be used as an auxiliary diagnostic method in conjunction with anxiety tests.

Chronic complications of spinal cord injury.

Spinal cord injury (SCI) is a serious medical condition that causes functional, psychological and socioeconomic disorder. Therefore, patients with SCI experience significant impairments in various aspects of their life. The goals of rehabilitation and other treatment approaches in SCI are to improve functional level, decrease secondary morbidity and enhance health-related quality of life. Acute and long-term secondary medical complications are common in patients with SCI. However, chronic complications especially further negatively impact on patients' functional independence and quality of life. Therefore, prevention, early diagnosis and treatment of chronic secondary complications in patients with SCI is critical for limiting these complications, improving survival, community participation and health-related quality of life. The management of secondary chronic complications of SCI is also important for SCI specialists, families and caregivers as well as patients. In this paper, we review data about common secondary long-term complications after SCI, including respiratory complications, cardiovascular complications, urinary and bowel complications, spasticity, pain syndromes, pressure ulcers, osteoporosis and bone fractures. The purpose of this review is to provide an overview of risk factors, signs, symptoms, prevention and treatment approaches for secondary long-term complications in patients with SCI.

Spinning-induced rhabdomyolysis: A case report and review of literature.

Rhabdomyolysis is a condition of skeletal muscle breakdown in which muscle injury causes a release of myoglobin and the muscle enzymes creatine phosphokinase (CPK), lactate dehydrogenase (LDH), and transaminases. Exertional rhabdomyolysis, which is precipitated by exercise or exertion, ranges from mild muscle injury with negligible symptoms or systemic effects to fulminant cases. Herein, we report a 26-year-old female patient who was admitted to our Physical Medicine and Rehabilitation outpatient clinics with severe bilateral thigh pain persisting for 5 days after participating in a spinning class and diagnosed with exertional rhabdomyolysis. Timely diagnosis and treatment prevented the potentially life-threatening consequences. We assume that it is essential to raise the awareness of this phenomenon not only by physicians but also by the community, since regular exercise and being physically active are increasingly encouraged in modern life.

Ultrasonographic evaluation of the median and sciatic nerves in hemiplegic patients after stroke.

OBJECTIVE: The aim of this study was to evaluate morphologically and electrophysiologically the peripheral nerves of hemiplegic patients. DESIGN: Thirty-three (18 women and 15 men) stroke patients were recruited. The mean (SD) age was 55.6 (11.3) yrs, and the mean (SD) disease duration was 14.2 (16.0) mos. Motor nerve conduction study of the median, ulnar, fibular, and tibial nerves as well as sensory nerve conduction study of the median, ulnar, and sural nerves were performed. Diameters and cross-sectional area (CSA) measurements of the median (wrist/midarm levels) and sciatic nerves (midthigh level) were acquired using a 7- to 12-MHz linear probe. The values of the nonparetic limbs were taken as controls. RESULTS: Prolonged distal latency and slowed motor conduction velocity of the tibial nerve as well as reduced amplitudes of the median and ulnar nerves were observed on the paretic sides when compared with those of the nonparetic sides (all P < 0.05). The median and sciatic nerve cross-sectional area values were found to be smaller on the paretic sides when compared with the nonparetic sides (all P < 0.05). The median and ulnar nerve compound muscle action potential amplitudes (paretic side) were positively correlated with arm/hand Brunnstrom Motor Recovery Stage, disease duration, motor Functional Independence Measure score, and Functional Ambulation Category. CONCLUSIONS: The peripheral nerves of stroke patients seem to be affected--morphologically and electrophysiologically--on the paretic side.

Doppler ultrasonographic evaluation of the radial and ulnar arteries in hemiparetic patients after stroke.

BACKGROUND: To evaluate blood flow of hand arteries (using Doppler ultrasonography) and sympathetic skin response (SSR) in patients with hemiparesis. METHODS: Fifty-six stroke patients (30 M, 26 F) with unilateral hemiparesis (age 53.5 ± 10.8 years, mean disease duration 12.0 ± 19.1 months) were included. The patients' arm and hand motor functions were assessed according to Brunnstrom's stages. SSR was evaluated bilaterally from median nerves at the wrist level. Radial and ulnar artery blood flow was measured at the wrist in the neutral position. RESULTS: Both radial and ulnar artery volume flow and end diastolic velocity, and radial artery diameter were smaller on the paretic side (all p < 0.0125). Radial artery resistance and pulsatility index were greater on the paretic side (both p < 0.0125). SSR amplitude was lower on the paretic side of patients with right-sided hemiparesis patients (p = 0.009). Hand Brunnstrom's stage was negatively correlated with nonparetic-paretic difference in radial artery volume flow and SSR amplitudes (all p < 0.025). CONCLUSIONS: Hand blood flow was lower on the paretic side and was accompanied by a similar decrease in SSR amplitudes in patients with right-sided hemiparesis.

Risk factors for developing heterotopic ossification in patients with traumatic brain injury.

OBJECTIVE: To evaluate the possible risk factors of heterotopic ossification (HO) in traumatic brain injury (TBI) patients. METHODS: A total of 151 patients with TBI were included. Demographical variables, laboratory investigations and risk factors for HO including spasticity, walking ability (using Functional Ambulation Category (FAC)), pressure ulcer, neurogenic bladder and systemic infection were recorded. RESULTS: Fifty-six patients (37.1%) had HO. Time since injury and serum ALP and ESR levels were significantly higher in HO patients than in non-HO patients. Hip (73.2%) and knee (44.6%) were the most commonly involved joints. This study has detected significant associations between FAC scores (FAC 0-1-2 vs. FAC 3-4-5, p < 0.001), degree of spasticity (p = 0.01), pressure ulcer (Absent/Grade 1 vs. Grade 2, 3 and 4, p = 0.001), presence of neurogenic bladder (p < 0.001) and systemic infection (p = 0.002) with the development of HO. According to the final logistical regression analysis, only lower FAC score was independently associated with HO development (p = 0.006). CONCLUSION: As lower scores of FAC is an independent risk factor for HO formation and is related to the severity and consequences of injury, ambulation and regular/cautious mobilization of the joints are of paramount importance in the early period of the rehabilitation in TBI patients.

Sonographic evaluation of sciatic nerves in patients with unilateral sciatica.

OBJECTIVES: To evaluate the sciatic nerves of patients with unilateral sciatica by using an ultrasound, and to determine whether ultrasonographic findings were related to clinical and electrophysiologic parameters. DESIGN: Cross-sectional study. SETTING: Physical medicine and rehabilitation departments of a university hospital and a rehabilitation hospital. PARTICIPANTS: Consecutive patients (N=30; 10 men, 20 women) with complaints of low back pain and unilateral sciatica of more than 1 month of duration were enrolled. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: All patients underwent a substantial clinical assessment, and they were also evaluated by electromyogram and magnetic resonance imaging. Pain was evaluated by a visual analog scale and the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Scale. A linear array probe (7.5-12MHz) was used to scan sciatic nerves bilaterally in the prone position. Sciatic nerve diameters-thickness (short axis) and width (long axis)-and cross-sectional areas were measured bilaterally at the same levels, proximal to the bifurcation and midthigh. The values pertaining to the unaffected limbs were taken as controls. RESULTS: When compared with the unaffected sides, mean values for sciatic nerve measurements-long axis at bifurcation level (P=.017) and cross-sectional area at midthigh level (P=.005)-were significantly larger on the affected sides. Swelling ratios negatively correlated with symptom duration (r=-.394, P=.038) and LANSS scores (r=-.451, P=.016) at only midthigh level. CONCLUSIONS: Sciatic nerves seem to be enlarged on the side of sciatica in patients with low back pain. Our preliminary results may provide insight into better understanding the lower limb radiating pain in this group of patients.

Levels of lipid peroxidation and antioxidant vitamins in plasma and erythrocytes of patients with ankylosing spondylitis.

OBJECTIVES: The aim of this study was to investigate plasma and erythrocytes antioxidant vitamins and lipid peroxidation (LP) levels in patients with ankylosing spondylitis (AS) and controls. METHODS: The study was performed on the blood of 13 AS patients and 13 controls. Plasma and erythrocyte samples were obtained from blood of the patients and controls. RESULTS: Erythrocyte sedimentation ratio, C-reactive protein level, Bath AS disease activity index and bath AS functional index were higher in patients with AS than in controls. Vitamins A, C, E and ß-carotene concentrations in plasma, reduced glutathione (GSH) and glutathione peroxidase values in erythrocyte were lower in patients with AS than in controls. LP concentrations were higher in the plasma and erythrocyte of the patients than in controls. CONCLUSION: These results provide some evidence for a potential role of increased lipid peroxidation and decreased antioxidant vitamins in ankylosing spondylitis.

Vitamins C and E treatment combined with exercise modulates oxidative stress markers in blood of patients with fibromyalgia: a controlled clinical pilot study.

We aimed to investigate effects of vitamins C and E (VCE) supplementation with exercise (EX) on antioxidant vitamin and lipid peroxidation (LP) levels in blood of patients with fibromyalgia (FM). A controlled study was performed on blood samples from 32 female FM patients and 30 age-matched controls. The patients were divided into three groups namely EX (n = 10), VCE (n = 11), and EX plus VCE (n = 11) after taking basal blood samples. After 12 weeks of EX and VCE supplementation, blood samples were taken once more from the patients. LP levels in plasma and erythrocytes were higher in the patients at baseline than those in controls, whereas LP levels were lower in the VCE and EX groups at the end of 12 weeks than those at baseline. Plasma concentrations of vitamins A and E and reduced glutathione were lower in the patients than those in controls and their concentrations were increased by VCE and EX. Glutathione peroxidase activity in erythrocytes was increased by VCE supplementation, with or without EX. Concentrations of ß-carotene in the groups did not change with treatment. Despite the measured effects on anti-oxidative mechanisms, FM symptoms were not improved by the treatments. In conclusion, VCE with EX may protect against FM-induced oxidative stress by up-regulation of an antioxidant redox system in the plasma and erythrocytes of patients with FM. Such protective effects of VCE in the patients seemed to be greater in combination with EX than EX alone.
