Assessment of the Clinical Use of Vestibular Evoked Myogenic Potentials and the Video Head Impulse Test in the Diagnosis of Early-Stage Parkinson's Disease.

OBJECTIVES: To explore the usefulness of vestibular tests including "vestibular evoked myogenic potentials" (VEMPs) and the video head impulse test (vHIT) in the early diagnosis of "idiopathic Parkinson's disease" (PD). MATERIALS AND METHODS: The study involved 80 participants including 40 patients (24 males, 16 females; age average 63.20 ± 7.94 years) with PD and 40 healthy individuals (18 males and 22 females; age average of 60.36 ± 7.68 years). The Modified Hoehn and Yahr (H&Y) scale was used to measure how Parkinson's symptoms progress and the level of disability. Patients with PD underwent cVEMPs, oVEMPs, and vHIT and the results were compared with those of 40 age-matched healthy control (HC) subjects. vHIT results and VEMP responses were registered in all patients and HCs. RESULTS: One-sided absent cVEMP responses were found in 6 (15%) patients with PD and 8 (20%) patients had bilaterally absent responses. Five (12.5%) patients had 1-sided absent oVEMP responses and it was bilateral in 6 (15%). Patients with PD had significantly shorter cVEMP P1, N1 latency, lower cVEMP amplitudes, and oVEMP amplitudes than the HC group. The cVEMP and oVEMP amplitude asymmetry ratio was significantly higher in the PD group (P < .05). Evaluation of vHIT results and vestibular-ocular reflex (VOR) gain between the groups revealed that anterior canal and posterior canal VOR gains results were remarkably lower in the PD group than in the HCs (P < .05). There was no difference in right and left lateral canal VOR gains between the groups (P > .05). CONCLUSION: The results of this study suggest that cVEMP and vHIT can be used to evaluate the vestibular system in patients with early-stage Parkinson's disease.

The efficacy of Kinesio taping on lymphedema following head and neck cancer therapy: a randomized, double blind, sham-controlled trial.

OBJECTIVE: The aim was to investigate the effectiveness of Kinesio taping for lymphedema following head and neck cancer therapy and its effect on patient compliance and quality of life. METHODS: A total of 66 patients with lymphedema following head and neck cancer therapy were randomly allocated to the therapeutic Kinesio taping group (n = 33) and the sham Kinesio taping group (n = 33). All participants received manual lymphatic drainage, Kinesio taping, and home exercises for the first four weeks, and only home exercises for the second four weeks. The tape measurements, a scale of external lymphedema, a scale of the internal lymphedema, and quality of life were evaluated in both groups. The perceived discomfort consisting of limitation of daily living activities, pain, tightness, stiffness, and heaviness were also recorded. RESULTS: When the group x time effect was evaluated, it was observed that external lymphedema was significantly reduced in both groups according to neck and face composite measurements (p < .001). However, in these measurements, a significant difference was found between the groups in favor of the KT group (p = .001, p = .032, respectively). At the end of the study, there was no significant difference in terms of internal lymphedema in both groups (p = .860). The quality of life parameters such as global health status and swallowing were significantly better in the Kinesio taping group (p < .001). There was no significant difference in the parameters of perceived discomfort between the two groups (p = .282, p = .225, p = .090, p = .155, p = .183, respectively). CONCLUSION: Kinesio taping is effective in tape measurements and positively affects the quality of life in lymphedema following head and neck cancer therapy.

Efficacy of Kinesio taping on Mutational Falsetto: A Double Blind, Randomized, Sham-controlled Trial.

OBJECTIVES: This study aimed to assess the efficacy of Kinesio taping on male patients with mutational falsetto undergoing voice therapy. DESIGN: Double blind, randomized, sham-controlled clinical trial. PARTICIPANTS: Interviews were conducted with thirty seven mutational falsetto patients. Included 32 participants were randomized and divided into two groups. Two were dropped out due to irregular attendance, 30 participants were included in final analysis. INTERVENTIONS: The study group was treated with voice therapy and applications of three different therapeutic Kinesio taping techniques with seven Kinesio tapes four times over two weeks, and the control group was treated with voice therapy, and applied to sham Kinesio taping. OUTCOME MEASURES: The values of fundamental frequency, jitter, shimmer, noise-harmonic ratio, maximum phonation time, Voice Handicap Index-10 scores, and Grade-Roughness-Breathiness-Asthenia-Strain Scale scores were recorded at the baseline and after the two weeks. RESULTS: There were significant differences between the study group and the control group with respect to the values of fundamental frequency (P = 0.011), jitter (P = 0.041), shimmer (P = 0.036), noise-harmonic ratio (P = 0.003), maximum phonation time (P ≤ 0.001), Voice Handicap Index-10 scores (P = 0.036), and Grade-Roughness-Breathiness-Asthenia-Strain Scale scores (P = 0.007; P ≤ 0.021; P = 0.022; P = 0.002; P = 0.021, respectively) at the end of the study. CONCLUSIONS: The study demonstrated that Kinesio taping with voice therapy is an efficient and effective technique for treating mutational falsetto patients.

Does forearm position matter in subpectoral biceps tenodesis? A randomised controlled trial.

INTRODUCTION: The optimal position of the elbow and forearm during biceps tenodesis is a debated topic. The aim of our study was to compare two different forearm positions, pronation-extension (PE) or neutral, for fixation of the long head of the biceps tendon (LHB) in biceps tenodesis. MATERIALS AND METHODS: Fifty patients who underwent shoulder arthroscopy between February 2016 and January 2019 were included in our study. After diagnostic arthroscopy, the LHB was cut from its origin with a thermal ablator. The LHB was then tenodesed beneath the inferior border of the pectoralis major tendon for 25 patients in the PE position and for 25 patients in the neutral position. Patients were evaluated preoperatively and 3rd, 6th and 12th months postoperatively according to the visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) shoulder and Constant scores. Flexion and supination force measurements were made with a digital dynamometer device, compared to the healthy side for both groups. RESULTS: ASES and VAS scores were statistically better in the PE group compared with the neutral group (p < 0.05), but there was no statistically significant difference between Constant scores at 3 and 6 months (p > 0.05). No significant difference was found in both groups for 3 scores at 12 months. Comparison of the PE group with the contralateral extremity and comparing the neutral group with the contralateral extremity in terms of flexion strength showed no statistically significant difference. No statistically significant difference was found between the supination powers of both comparative groups. CONCLUSION: Functional scoring in the PE position is better at 3 and 6 months because patients experience less pain at 3 and 6 months. The simple change of the fixation position causes patients to feel less pain in the early period.

Shoulder Proprioception Following Reverse Total Shoulder Arthroplasty for Unreconstructable Upper Third Fractures of the Humerus: 2-Year Outcomes.

Background: Proximal humerus fractures may be comminuted in the elderly or after injury with high-energy mechanisms. Reverse total shoulder arthroplasty that may affect shoulder proprioception (rTSA) has also begun to play a part in treating acute proximal humeral fractures. In this study, the authors aimed to evaluate joint position sense (JPS) after rTSA. Methods: Humac Norm II isokinetic device was used to evaluate the joint position sense. A joint angle was determined and the ability of the patient to create the same value of the angle by the active movement was evaluated. The difference between the pre-determined angle and the patient's measured angle was recorded. For proprioceptive sense, the initial position was 0° and the determination position was 30°, 60°, and 90° for flexion and abduction, and 15° and 30° for internal rotation and external rotation. Results: While both the mean Constant and ADLEIR scores did not differ between non-operated and operated sides, the mean proprioception differences in all flexion (30°, 60°, and 90°), abduction (30°, 60°, and 90°), internal rotation (15° and 30°), and external rotation (15° and 30°) were significantly higher in the operated side than that in non-operated side (p < 0.01 for each pairwise comparison). Conclusion: Reverse total shoulder arthroplasty (rTSA) treatment, which has increasingly become a surgical option in un-reconstructable proximal humeral fractures has significant adverse effects on proprioception on the operated side and may pose a risk for long-term instability, premature loosening, and prosthesis mechanical complications, in this context, well-designed prospective controlled studies are required.

Effect of adenoid hypertrophy and adenoidectomy on bite force in children: Twelve month follow-up, case-control study.

OBJECTIVE: The effects of adenoid hypertrophy (AH) and adenoidectomy on maximal bite force (MBF) in patients were evaluated by comparing them with healthy controls. METHODS: A total of 118 children diagnosed with AH and undergoing adenoidectomy (Group A), and healthy controls (Group B) were included. The MBF and nasopharyngeal airway passage distance (NAPD) were recorded. RESULTS: There was a correlation between NAPD and MBF at the beginning of the study (r = -0.675 and p < 0.001). The initial mean MBF of Groups A and B were 318.37 ± 70.76 N and 344.04 ± 64.14 N, respectively (p = 0.041). However, there was no significant difference between the groups due to the increase in the MBF of Group A at 12 months (p = 0.165). CONCLUSION: The MBF may be negatively affected in proportion to decreased NAPD, and it could also be an indicator for monitoring the status of children with AH.

Validity and Reliability of the Turkish Version of the Sydney Swallow Questionnaire.

PURPOSE: This study aimed to assess the validity and reliability of the Turkish version of the Sydney Swallow Questionnaire (SSQ-T) and calculate a cutoff value to help clinicians to suspect/predict oropharyngeal dysphagia (OPD). METHOD: The original questionnaire was translated into Turkish by two bilingual English Turkish translators. The study included 170 Turkish adult subjects. Half of the participants were patients presenting with OPD, and half were healthy controls. Fiberoptic endoscopic evaluation of swallowing (FEES) was administered to all subjects. Patients were evaluated using the Turkish Penetration Aspiration Scale and the Yale Pharyngeal Residue Severity Rating Scale. Additionally, the final version of the SSQ-T questionnaire and the Turkish Eating Assessment Tool were administered to all subjects. RESULTS: Internal consistency was high on all questions (Cronbach's α = .974). Test-retest reliability was also high (intraclass correlation coefficient = .975, p < .001; 95% confidence interval [.948-.988]). The SSQ-T score range was 0-1,240 for all participants, 57-1,240 for the patients with OPD, and 0-152 for the healthy controls. The cutoff value was 174 with 85.96% sensitivity and 99.12% specificity. CONCLUSION: The SSQ-T was demonstrated to be a valid and reliable assessment to assess the self-perceived severity of OPD.

Kinesiotaping therapy for midshaft clavicular fractures: a randomised trial study.

Midshaft clavicle fractures with shortening by less than 2 cm or minimal displacement without neurovascular injury can be treated conservatively. We hypothesized that kinesiotaping reduces the disadvantages of conservative treatment, such as early-phase pain, high nonunion rates, and a prolonged time to return to work, and yields better clinical and functional outcomes. Forty patients were randomly divided into the arm slings only (group S) or arm sling with kinesiotaping therapy group (group K). The outcome measures included the visual analog scale (VAS) score, Constant score, American Shoulder and Elbow Surgeons (ASES) score, union time, magnitude of shortening, and time to return to work. The mean follow-up period of the study was 8.5 (6- 10) months. The ASES and Constant scores were significantly better in group K than in group S in the 3rd month. The mean union time was 8.60 (8-12) weeks in group S and 8.25 (6-12) weeks in group K. The mean time to return to work was 7.23 (4-12) weeks in group S and 5.37 (2-10) weeks in group K, and the difference was statistically significant (p <0.05). There was no significant difference in terms of shortening between the two groups. Compared with an arm sling only, an arm sling with kinesiotaping can yield better clinical functional results, higher union rates, and a shorter the time to return to work due to the early control of pain and edema.

Comparison of Pain, Muscle Strength, and Functional Status Following Unicompartmental Knee Arthroplasty, Total Knee Arthroplasty, and Conservative Management of Gonarthrosis.

BACKGROUND: Treatment options and surgical decision for grade 3-4 gonarthrosis remains controversial. We aimed to compare the pain level, muscle strength, physical performance, lower extremity functions, and other physical activity levels between patients who underwent arthroplasty and those who received conservative management for grade 3-4 gonarthrosis. METHODS: This prospective analytical observational study was conducted in a tertiary referral hospital. A total of 30 unicompartmental knee arthroplasty (UKA) and 30 total knee arthroplasty (TKA) patients as two different study groups and 30 patients were treated conservatively as the control group were included. The rehabilitation and complication rates were recorded. The values of the range of motion, quadriceps diameter, were measured and also the isokinetic muscle strength, pick-up, repeated sit-to-stand, stair ascending and descending, straight-line walking, timed up and go, and 20-m walk tests, the knee injury and osteoarthritis-outcome-score (KOOS), the hospital for special-surgery-knee-score (HSS), and Oxford-Knee-Score (OKS) were performed. RESULTS: Postoperative rehabilitation and complication rates were significantly higher in the TKA group compared to the UKA group (p = 0.029 and p = 0.026, respectively). Six months after the treatment, the knee extension muscle strength value at 180°/s, knee flexion degree, total work flexion, stair ascending, VAS at night, all KOOS symptom, pain and daily function and total scores in the UKA group was significantly different than the TKA and the control groups (p < 0.001). Total work extension values, knee flexion degree, in the control group were found to be significantly higher than the TKA group (p = 0.033, p < 0.001, respectively). CONCLUSIONS: The UKA was significantly superior to TKA and conservative treatment concerning pain, muscle strength, and quality of life. LEVEL OF EVIDENCE: IIa.

Evaluation of the physical and emotional effects of the COVID-19 pandemic on patients with fibromyalgia and chronic low back pain: A multicenter cross-sectional controlled study.

Objectives: This study aimed to investigate the physical and emotional effects of the coronavirus disease 2019 pandemic in patients with fibromyalgia syndrome (FMS) and chronic low back pain (CLBP) patients. Patients and methods: The cross-sectional controlled study was performed with 1,360 participants (332 males, 1,028 females; mean age: 42.3±12.5 years; range, 18 to 65 years) between September 2020 and February 2021. The participants were evaluated in three groups: the FMS group (n=465), the CLBP group (n=455), and the healthy control group (n=440). Physical activity, pain levels, and general health status before and during the pandemic were evaluated in all participants. Stress levels were analyzed with the perceived stress scale (PSS) in all groups, and disease activity was analyzed with the fibromyalgia impact questionnaire (FIQ) in patients with FMS. Results: Patients with FMS had worsened general health status and pain levels during the pandemic compared to the other groups (p<0.01). The FMS group showed significantly higher PSS scores than those in other groups (p<0.01). There was a weak-positive correlation between FIQ and PSS parameters in patients with FMS (p<0.05, r=0.385). Conclusion: The general health status, pain, and stress levels of the patients with FMS and CLBP tended to worsen during the pandemic. This high-stress level appeared to affect disease activity in patients with FMS.

Validity and Reliability of the Turkish Translation of the Yale Pharyngeal Residue Severity Rating Scale.

This study aimed to assess the validity and reliability of the Turkish translation of the Yale pharyngeal residue severity rating scale. The scale measures the severity of residue in the vallecula and pyriform sinus. The original scale was translated into Turkish by two bilingual English-Turkish translators, and the Turkish version was translated back into English by two qualified professional translators to assess accuracy. The evaluators were divided into two groups (training and no-training) and two subgroups according to their experience. Intra-rater, inter-rater, and intra-class correlation coefficient measurements were analyzed by calculating agreement rates, kappa, and p values. In the analysis of the reliability, intra-class correlation coefficient values in the overall ratings for both the vallecula and the pyriform sinus were 0.9996 (95% CI 0.9992-0.9998) and 0.9997 (95% CI 0.9995-0.9999), respectively (p < 0.01). High agreement (> 95%) and perfect Fleiss kappa values were obtained for the vallecula and pyriform sinus ratings in the inter-rater initial assessments (κ = 0.959 and κ = 0.967, respectively). Perfect kappa values were found in the intra-rater results for both the vallecula and pyriform sinus (α = 0.9959 and κ = 0.9959, respectively). In the inter-rater secondary analysis, the vallecula and pyriform sinus kappa values were perfect (κ = 0.959 and κ = 0.967, respectively). In the intra-rater analysis, perfect kappa values were obtained for the vallecula and pyriform sinus in the no-training group and less-experience subgroup (κ = 0.9918 and κ = 1.0 for the vallecula, and κ = 1.0 and κ = 0.9902 for the pyriform sinus, respectively) In the inter-rater analysis, perfect kappa values were obtained for the vallecula and pyriform sinus in the no-training group and less-experience subgroup (κ = 0.9507 and κ = 0.9606 for the vallecula, and κ = 0.9836 and κ = 1.0 for the pyriform sinus, respectively). The Turkish translation of the Yale pharyngeal residue severity rating scale demonstrated high validity and reliability scores in determining pharyngeal residue location and value in the fiberoptic endoscopic evaluation of swallowing.

Evaluation of the Swallowing and Voice Functions in Ankylosing Spondylitis Patients.

This study aimed to evaluate the swallowing and voice functions in patients with ankylosing spondylitis. Thirty patients with ankylosing spondylitis (Group 1) and 30 healthy individuals (Group 2) were included in the study. Following the laryngoscopic evaluation of the patients, the fiberoptic endoscopic evaluation of swallowing was performed, and then, the penetration-aspiration score was determined. The participants were asked to fill the eating assessment tool form. Voice recordings obtained to evaluate sound disorders were measured acoustically and analyzed using the PRAAT program. In terms of swallowing, the penetration-aspiration score obtained as a result of the flexible endoscopic swallowing assessment and eating assessment tool score was found to be higher in Group 1 than in Group 2, and a statistically significant difference was noted (p ≤ 0.001). When analyzing the maximum phonation time (p < 0.001) and fundamental frequency (p = 0.408) values in phonation evaluation, a statistically significant difference was found between the two groups. Group 1 showed a deterioration in terms of jitter (p = 0.040) and shimmer (p = 0.007) compared to Group 2, and a statistically significant difference was noted. There was no statistically significant difference in the harmonic/noise ratio (mean ± standard deviation) between the two groups (p = 0.051). Swallowing and voice functions significantly affect quality of life. Therefore, approaches aimed to improve the associated symptoms have become increasingly important. In patients with ankylosing spondylitis, swallowing quality and phonation ability may be negatively affected. These patients should be monitored for hidden or overt food aspiration.Trial Registry: https://clinicaltrials.gov/ct2/show/NCT04437394.

The effect of gluteus maximus tenotomy in primary total hip arthroplasty with posterior approach: Kinematic analysis of hip extensor strength.

BACKGROUND: The posterior approach (PA) is the most commonly used surgical approach for total hip arthroplasty (THA), but the proximity of the sciatic nerve may increase the likelihood of sciatic nerve injury (SNI). Gluteus maximus tenotomy can be performed to prevent SNI because tenotomy increases the distance between the femoral neck and sciatic nerve and prevents compression of the sciatic nerve by the gluteus maximus tendon (GMT) during hip movements. We aimed to kinematically compare the postoperative hip extensor forces of patients who have and have not undergone gluteus maximus tenotomy to determine whether there is a difference in hip extensor strength. METHODS: Seventy-two patients who underwent gluteus maximus tenotomy during THA were included in the group 1, and 86 patients who did not undergo tenotomy were included in group 2. The Harris hip score, body mass index and hip extensor forces were measured both preoperatively, and 6 months after surgery with an isokinetic dynamometer and compared. RESULTS: The mean age was 64.6 ± 2.3 years in group 1 and 63.8 ± 2.1 in group 2. Mean body mass index was 25.7 ± 1.1 in group 1, and 25.5 ± 1.3 in group 2. Baseline Harris hip score (HHS) was 42.36 ± 12 in group 1 and 44.07 ± 9.4 in group 2 (p = 0.31), whereas it was 89.1 ± 7.8 and 88.4 ± 8.1 at 6 months after surgery, respectively. Baseline hip extensor force (HEF) was 2 ± 0.4 Nm/kg in group 1, and 2.1 ± 0.7 Nm/kg in group 2 (p = 0.28), while it was 2.4 ± 0.6 Nm/kg, and 2.5 ± 0.5 Nm/kg, respectively at 6 month follow-up (p = 0.87). Both groups had significantly improved HHS and HEF when comparing baseline and postoperative measurements (p < 0.0001). No cases of sciatic nerve palsy were noted in group 1, whereas there were two (2.32%) cases in group 2, postoperatively. CONCLUSION: The release of the GMT during primary hip arthroplasty performed with the PA did not lead to significant decrease in hip extension forces. Hip extensor strength improves after THA regardless of tenotomy. Gluteus maximus tenotomy with repair does not reduce muscle strength and may offer better visualization.

Prevalence, etiology, and biopsychosocial risk factors of cervicogenic dizziness in patients with neck pain: A multi-center, cross-sectional study.

OBJECTIVES: This study aims to investigate the prevalence, etiology, and risk factors of cervicogenic dizziness in patients with neck pain. PATIENTS AND METHODS: Between June 2016 and April 2018, a total of 2,361 patients (526 males, 1,835 females; mean age: 45.0±13.3 years; range, 18 to 75 years) who presented with the complaint of neck pain lasting for at least one month were included in this prospective, cross-sectional study. Data including concomitant dizziness, severity, and quality of life (QoL) impact of vertigo (via Numeric Dizziness Scale [NDS]), QoL (via Dizziness Handicap Inventory [DHI]), mobility (via Timed Up-and-Go [TUG] test), balance performance [via Berg Balance Scale [BBS]), and emotional status (via Hospital Anxiety- Depression Scale [HADS]) were recorded. RESULTS: Dizziness was evident in 40.1% of the patients. Myofascial pain syndrome (MPS) was the most common etiology for neck pain (58.5%) and accompanied with cervicogenic dizziness in 59.7% of the patients. Female versus male sex (odds ratio [OR]: 1.641, 95% CI: 1.241 to 2.171, p=0.001), housewifery versus other occupations (OR: 1.285, 95% CI: 1.006 to 1.642, p=0.045), and lower versus higher education (OR: 1.649-2.564, p<0.001) significantly predicted the increased risk of dizziness in neck pain patients. Patient with dizziness due to MPS had lower dizziness severity scores (p=0.034) and milder impact of dizziness on QoL (p=0.005), lower DHI scores (p=0.004), shorter time to complete the TUG test (p=0.001) and higher BBS scores (p=0.001). CONCLUSION: Our findings suggest a significant impact of biopsychosocial factors on the likelihood and severity of dizziness and association of dizziness due to MPS with better clinical status.

The effect of transcutaneous electrical nerve stimulation (TENS) on chronic subjective tinnitus.

OBJECTIVES: Chronic Subjective Tinnitus is a very highly prevalent disorder worldwide. There is no definitive treatment. The aim of this study is to investigate the efficacy of transcutaneous electrical nerve stimulation (TENS) applied to the auricula for treating tinnitus using the Depression Anxiety Stress Scales (DASS) and Tinnitus Handicap Inventory (THI). METHODS: The 60 patients were randomly divided into 3 groups of 20 patients. The first group (A) had one ear stimulated with TENS, and the second group (B) had both ears stimulated. Group C (placebo group) received no electrical or sound stimulation. All group patients received total of 10 sessions with a maximum of 4 days between the sessions. RESULTS: The THI and DASS scores decreased significantly after the treatment (p < 0.05). A significant difference was also observed between the groups after treatment (p < 0.05). While there was no difference between group A and B, it was shown that group C's post-treatment score was significantly higher than those of both groups (p < 0.05.) CONCLUSION: It is important to note that TENS has a therapeutic effect on subjective chronic tinnitus as well as a placebo effect.

Evaluation of the Relation Between Omentin-1 and Vitamin D in Postmenopausal Women With or Without Osteoporosis.

INTRODUCTION: Crosstalk between bone and adipose tissues is implicated in several pathologic conditions related to bone metabolism. Omentin-1, a 34-kD protein, is released from omental adipose tissue. A few studies indicated the effect of omentin-1 on bone health and bone mineral density (BMD) and the interaction of omentin-1 with vitamin D. Therefore, this study aimed to investigate the relationship between omentin-1, vitamin D, and BMD in postmenopausal women with osteoporosis compared with non-osteoporotic counterparts. MATERIALS AND METHODS: Forty postmenopausal women with osteoporosis (OP), 40 counterparts without OP, and 30 premenopausal women were enrolled. Dual-energy X-ray Absorptiometry results, body mass index, and some demographic and biochemical data were recorded. Vitamin D (25-hydroxyvitamin D3) levels were measured using liquid chromatography-tandem mass spectrometry. Serum omentin-1 was determined using an enzyme-linked immunosorbent assay. RESULTS: Omentin-1 levels tended to increase in both postmenopausal women groups compared with the control group, but this increase was significant only in women with osteoporosis. Vitamin D levels were not different between the groups. When women were categorized according to vitamin D levels, women with normal vitamin D levels had significantly higher omentin-1 levels. A positive correlation was found between omentin-1 and vitamin D levels in all groups (r=0.197, p=0.041, n=110). CONCLUSION: The tendency to an increase in omentin-1 levels in postmenopausal women with osteoporosis may be due to a physiologic compensation against bone loss after menopause. The linear relationship between omentin-1 and vitamin D suggests that adipose tissue is one of the target tissues for the vitamin D effect.

The reliability and validity of the Turkish version of fibromyalgia survey diagnostic criteria and symptom severity scale.

BACKGROUND: The fibromyalgia survey diagnostic criteria and severity scale (FSDC) is a self-reported version of 2010 preliminary diagnostic criteria for fibromyalgia syndrome (FMS). FSDC not only facilitates to diagnose FMS, it measures pain (the Widespread Pain Index (WPI)/FSDC Section 3), the Symptom Severity (SS)/FSDC Sections 1 and 2, and provides a score, polysymptomatic distress (PSD)/FSDC Total score in patients with FMS. The purpose of our study is to evaluate the reliability and validity of Turkish version of FSDC in Turkish patients with FMS. METHODS: The Turkish version FSDC was obtained by two forward translations of the instrument into Turkish by two bilingual Turkish individuals, one of them was a physician. They were then back translated into English by two different bilingual individuals; another Turkish physician and a backtranslator whose mother tongue was English. The original version of FSDC, the two Turkish forward translations, and English back translations were then reviewed by the individuals involved in translations, and the last experimental Turkish version was created. This last version of Turkish FSDC studied on patients with newly diagnosed FMS by using American College of Rheumatology (ACR) 1990 classification criteria. Patients filled validated Turkish revised fibromyalgia impact questionnaire (rFIQ), our nonvalidated experimental Turkish FSDC; marked Visual Analog Scale (VAS) for pain and the disease severity. In 7 to 15 days, they have filled the nonvalidated Turkish FSDC for the second time. RESULTS: In 132 patients, by the test to retest reliability analysis of nonvalidated Turkish FSDC, for the 25 single items, correlation coefficients ranged 0.383 to 0.818 (all p< 0.01). There were significant correlations between nonvalidated Turkish FSDC assessment 1 and assessment 2 for Section 1+2 (SS) (r = 0.748), Section 3 (WPI) (r = 0.775), and the total scores (PSD) (r = 0.821) (all p< 0.01). Cronbach alpha was 0.766 for the nonvalidated Turkish FSDC assessment 1 total score, and 0.77 for the Turkish FSDC assessment 2 total score. There were significant correlations between nonvalidated Turkish FSDC assessment 1 total score and total rFIQ (r= 0.576), VAS pain (r= 0.443), VAS disease severity (r= 0.342) (all p< 0.01). Our results indicated that 94.7 % to 96 % of our patients satisfying 1990 FMS criteria also satisfied 2010 modified diagnostic criteria. CONCLUSIONS: The Turkish experimental version of FSDC is a reliable and valid instrument in Turkish FMS patients. It is easily completed, simple to score providing valuable instrument to diagnose and follow FMS.
