Background The aim of this study was to evaluate sleep quality and the related variables in patients with rheumatoid arthritis (RA). Methods Ninety-four patients diagnosed with RA and fifty two healthy controls were enrolled in the study. Disease activity was assessed through the Disease Activity Score (DAS) 28 scale. All patients were assessed using the Rheumatoid Arthritis Quality of Life and Health Assessment Questionnaire scales, together with the Beck Depression Inventory. Radiological damage was calculated with the modified Larsen method. The Pittsburgh Sleep Quality Index (PSQI) was used for the evaluation of the sleep disturbance. Results The patients with RA had significantly higher scores in the subjective sleep quality, sleep latency, habitual sleep efficiency, sleep disturbance domains and the total PSQI score compared to the healthy control group. According to the results of Spearman’s analysis, there was a significantly correlation between the age, disease activity, CRP, pain, fatigue, depression, functional disability, quality of life, radiological damage, menopause status, duration of morning stiffness, ESR levels and the sleep disturbance. The logistic regression analysis indicated that depression and DAS 28 scores were predictors for poor sleep quality. Conclusion The sleep quality is disturbed in patients with RA. The poor sleep quality is especially associated with the disease activity and depression.

BACKGROUND The loss of cervical lordosis is associated with some negative clinical outcomes. No previous study has examined cervical muscle strength, specifically in patients with the loss of cervical lordosis. This study aims to investigate whether there is weakness of the cervical muscles or an imbalance between cervical flexor and extensor muscle strength in patients with the loss of cervical lordosis compared with healthy controls matched by age, gender, body mass index (BMI), and employment status. METHODS Thirty-two patients with the loss of cervical lordosis (23 F, 9 M) and 31 healthy volunteers (23 F, 8 M) were included in the study. Maximal isometric neck extension and flexion strength, and the strength ratio between extension and flexion were used as evaluation parameters. All measurements were conducted by a blinded assessor using a digital force gauge. The participants were positioned on a chair in a neutral cervical position and without the trunk inclined during measurements. FINDINGS Maximal isometric neck extension and flexion strength values were significantly lower in the patients versus healthy controls (P<0.001 and P=0.040, respectively). The mean (SD) values of the extension/flexion ratio were 1.21 (0.34) in the patients and 1.46 ± 0.33 in the controls (P=0.004). INTERPRETATION According to our results, patients with the loss of cervical lordosis have reduced neck muscle strength, especially in the extensors. These findings may be beneficial for optimizing cervical exercise prescriptions.

Objective: To investigate the efficacy of intermittent and continuous traction in the treatment of knee osteoarthritis. Design: A randomized, controlled, observer-blind seven-week trial. Setting: Hospital-based outpatient practice. Subjects: Ninety-eight patients with stage 3 knee osteoarthritis according to Kellgren–Lawrence radiological rating scale. Interventions: All 98 patients were randomly assigned to three treatment groups, for three weeks (weekends excluded). The control group (n=30, mean age: 59.30±8.16) received hot pack and short wave diathermy; the intermittent group (n=30, mean age: 58.20±7.78) received hot pack, short wave diathermy and intermittent traction; and the continuous group (n=30, mean age: 57.97±9.53) received hot pack, short wave diathermy and continuous traction. Outcome measurements: The values of the Turkish version of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale, and knee passive range of motion were measured at baseline, three-week and seven-week follow-up. Results: Compared with baseline at weeks 3 and 7, all the outcome measures, except range of motion, were significantly reduced in all groups (all P≤0.001). In terms of the change data from baseline to week 3, both traction groups were significantly superior to the control in the WOMAC physical function scores. Considering the change data from baseline to week 7, both traction groups were significantly superior to the control in the pain scores, physical function and total scores, while only the continuous group was significantly better than the control in the stiffness scores (control: 1.17 ± 1.64; continuous: 2.38 ± 1.44) (P=0.014). Compared with baseline at weeks 3 and 7, range of motion values significantly increased in both traction groups (P<0.05) but not in the control (P>0.05). However, there were no significant differences among the three groups considering the change data from baseline to week 7 in range of motion values (P=0.300). Conclusions: Joint traction was found to be beneficial for the improvement of pain and physical function loss related to knee osteoarthritis.

ABSTRACT Purpose: To evaluate corneal parameters of scleroderma (SC) patients by Pentacam-HR. Methods: Twenty-two eyes of 22 SC patients and 33 eyes of 33 control subjects were enrolled. All participants underwent Pentacam (Pentacam-HR, Oculus, Germany) evaluation. Both SC and control groups were divided into two subgroups as dry eye (DE) (Schirmer test with topical anesthesia (STA) ˂5 mm) and without DE (STA ˃5 mm). Results: Pachymetric measurements and mean corneal volume (CV) were significantly lower in the SC group than in the control group (p<0.001). Pachymetric measurements and CV of SC patients with DE were significantly lower than all the other subgroups. Control subgroups with or without DE were similar in pachymetric measurements and CV. Conclusions: The results suggest that SC patients have thinner corneas compared with control subjects. Additionally, coexistence of DE seems to have an additional impact in the thinning of cornea in SC patients.

Growth differentiation factor‐15 (GDF‐15), a member of the transforming growth factor‐β superfamily of cytokines, plays an important role in cell growth, signal transduction, and apoptosis regulation. The aim of this study was to evaluate serum GDF‐15 levels and their relationships with disease‐related variables in patients with Behçets disease (BD). Forty‐six patients diagnosed with BD and 30 demographically matched healthy control subjects participated in the study. GDF‐15 levels were measured in blood samples from patients and controls. The Behçets Disease Current Activity Form (BDCAF) was used to evaluate the disease activity of BD. There were no significant differences between the two groups in C‐reactive protein (CRP) level, mean erythrocyte sedimentation rate (ESR), age, body mass index, and mean GDF‐15 levels (P > 0.05). Serum GDF‐15 levels were positively correlated with findings for peripheral arthritis and CRP, and with BDCAF erythema nodosum, BDCAF arthralgia, and BDCAF arthritis scores. Patients with BD were divided into two groups according to the presence of peripheral arthritis; nine subjects (20%) were positive for peripheral arthritis. Serum ESR, CRP, white blood cell counts, and GDF‐15 levels were significantly higher in the group that was positive for peripheral arthritis (P < 0.05). GDF‐15 may play a role in the progression and pathway of Behçets joint involvement and erythema nodosum that is independent of classic inflammatory response measures.

Background Because loss of cervical lordosis leads to disrupted biomechanics, the natural lordotic curvature is considered to be an ideal posture for the cervical spine. The vertebral arteries proceed in the transverse foramen of each cervical vertebra. Considering that the vertebral arteries travel in close anatomical relationship to the cervical spine, we speculated that the loss of cervical lordosis may affect vertebral artery hemodynamics. The aim of this study was to compare the vertebral artery values between subjects with and without loss of cervical lordosis. Material/Methods Thirty patients with loss of cervical lordosis and 30 controls matched for age, sex, and body mass index were included in the study. Sixty vertebral arteries in patients with loss of cervical lordosis and 60 in controls without loss of cervical lordosis were evaluated by Doppler ultrasonography. Vertebral artery hemodynamics, including lumen diameter, flow volume, peak systolic velocity, end-diastolic velocity, and resistive index, were measured, and determined values were statistically compared between the patient and the control groups. Results The means of diameter (p=0.003), flow volume (p=0.002), and peak systolic velocity (p=0.014) in patients were significantly lower as compared to controls. However, there was no significant difference between the 2 groups in terms of the end-diastolic velocity (p=0.276) and resistive index (p=0.536) parameters. Conclusions The present study revealed a significant association between loss of cervical lordosis and decreased vertebral artery hemodynamics, including diameter, flow volume, and peak systolic velocity. Further studies are required to confirm these findings and to investigate their possible clinical implications.

Objectives This study aims to investigate the frequency of fibromyalgia syndrome and to specify fibromyalgia syndrome-associated clinical symptoms in patients with acne vulgaris. Patients and methods Eighty-eight patients (28 males, 60 females; mean age 23.2±5.1 years; range 18 to 40 years) with acne vulgaris and age, sex- and body mass index-similar 76 healthy controls (14 males, 62 females; mean age 24.5±2.9 years; range 18 to 35 years) were included. Acne vulgaris was evaluated by using the Global Acne Scale, while Hospital Anxiety and Depression Scale was used to evaluate anxiety. Results Fibromyalgia-associated pain, sleep disturbance, anxiety, and menstrual cycle disturbance were significantly more frequent in patients with acne vulgaris than controls. Also, the severity of anxiety and the number of tender points were significantly higher in the acne vulgaris patients than controls. Conclusion This study indicates that patients with acne vulgaris have increased frequency of fibromyalgia syndrome than healthy controls (21.6% versus 5.3%, respectively).

BACKGROUND Subacromial impingement syndrome (SIS) is characterized by pain and disability of shoulder. Various treatment methods have been used for SIS. OBJECTIVES The aim of our study was to evaluate efficacy of therapeutic ultrasound (US) on pain, disability, anxiety, depression, sleep quality and quality of life in patients with SIS. METHODS Patients with SIS were randomly divided into two groups, including the group 1 (continuous US group; 3 MHz, 1.5 W/cm2, n = 26) and group 2 (sham US group, n = 24). Additionally, transcutaneous electrical nerve stimulation (TENS) + exercise program were added in both groups. Pain and disability of the shoulder were assessed by the Shoulder Pain and Disability Index (SPADI), while anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality. Quality of life was evalutaed by the Nottingham Health Profile (NHP). Patients were evaluated at baseline and after end of three weeks. RESULTS Both groups had significantly improvements in terms of SPADI-pain, SPADI-disability, SPADI-total, NHP-pain and NHP-sleep scores after the three weeks interventions. There were significantly improvements in the Group 1 in terms of PSQI-total, and NHP-physical activity. Group 2 had significantly improvements in terms of anxiety-HADS, depression-HADS and NHP-emotional reaction scores. In the inter-group comparison, there were no significantly differences in the change scores were observed in any domains of SPADI scores, anxiety, depression and sleep scores, or any NHP scores. CONCLUSIONS Our study showed that US does not have any benefits on SIS. TENS + exercise program are not effective on anxiety, depression and fatigue, however TENS +
