In this study, it has been shown that foot deformities are frequent in patients with RA and that there is slight deterioration in foot functions related to RA. Our results indicated that foot deformities have small, but clinically important changes on foot functions. There is a need for more studies, which evaluates the foot deformities, to further explore the relationship between the foot deformities and foot function in patients with RA.

Objectives To adapt and validate the OAKHQOL for using in osteoarthritis patients of Turkish population. Methods The cross-cultural adaptation of OAKHQOL according to guideline used forward and backward translations from French to Turkish, with an emphasis on expert committee informed decision making. Patients with knee and hip osteoarthritis were recruited into the study. Systemic inflammatory rheumatic diseases were in exclusion criteria. Internal consistency of OAKHQOL subgroups were assessed. Face and content validity were assessed via cognitive debriefing interviews with OA patients. The OAKHQOL subgroups were correlated with SF36, Lequesnes index, Nothingam Health Profile (NHP), WOMAC and VASpain to evaluate construct validity. Spearman correlation coefficient managed to compare qualitative parameters. p<0.05 was significant. Results Eighty two patients (63 female) with aged 56,31 (SD:11,12) years were recruited. Sixtynine patients had osteoarthritis at knees, 11 had at hips and 2 patients had both. The Body Mass Index (BMI) was 27,19 (SD:3,90) and the disease duration was 4,77 years (range: 0,5 – 30). The internal consistency of OAKHQOL subgroups (1 to5) were 0,80; 0,51; 0,87; 0,77 and 0,31. The mean scores of subgroups were 47,19 (SD: 19,77); 42,46 (SD: 34,58); 56,47 (SD: 22,96); 59,92 (24,89) and 49,75 (34,32). According to expert and patient desicions the Turkish version of OAKHQOL had good face and content vaidity. The physical activity, pain and mental health subgroups of OAKHQOL had significant correlation with all subgroups of SF36. The social support and social activities subgroups had not significant correlation with SF36 scores. Lequesnes index had good correlation only with physical activity (p=0,001) and pain (p<0,0001) subgroups of OAKHQOL. The total score of WOMAC had significant correlation with the physical activity (p=0,001), pain (p=0,001) and mental health (p=0,001) subgroups of OAKHQOL. Physical activity and pain subgroups of NHP had significant correlation only with the physical activity, pain and mental health subgroups of OAKHQOL. There was not any significant correlation with social support and social activities subgroups of OAKHQOL with other quality of life scales. Conclusions The psychometric properties of Turkish version of OAKHQOL show that it is useful scale to assess the quality of life of patients with knee and hip osteoarthritis in our population.

Background Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis (1). PsA and its associated psoriatic skin lesions have been found to lower the health-related quality of life, effecting physical functioning and psychosocial well-being (2). Impairment of sleep and quality of life are important symptoms in PsA. Objectives Assesment of sleep quality and its relation with quality of life in PsA patients. Methods 40 patients fulfilling Caspar criteria for psoriatic arthritis were selected for this study. Patients with malignancy, fibromyalgia syndrome and other systemic inflammatory rheumatic diseases were excluded. Various clinical data including patients’ general health and pain assesment with visual analog scale (VAS), morning stiffness, duration of psoriasis and psoriatic arthritis were recorded. Sleep disturbance was evaluated with Pittsburgh Sleep Quality Index (PSQI). Quality of life was assessed with Psoriatic Arthritis Quality of Life (PSAQol) and Notthingham Health Profile (NHP). Maastricht Ankylosing Spondylitis EnthesitisScore (MASES) was used for evaluation of enthesitis. Results 40 patients (14 men, 26 women) were recruited into this study. The mean age of patients was 46,06 years and the median disease duration was 9 months. Mean score for PSOI was 5,66±3,66. 44,8 % of patient were calssified to be poor sleepers (PSOI>5). No significant correlations could be found between PSQI and VAS for pain, VAS for general health, disaese duration, morning stiffness, PASI and MASES scores. Howewer, there was a significant correlation between PSQI scores and NHP total score (p=0,001, r=0,610) and PsAQoL score (p=0,029, r=0,477). There was a statistically significant positive correlation between PsAQoL score and VAS for pain scores (p=0,002, r=0,552); with VAS for general health scores (p=0,010, r=0,471) and with MASES (p=0,001, r=0,653). There was no significant correlation between PSAQoL and erytrhocyte sedimentation rate, PASI, duration of psoriatic arthritis, duration of psoriasis Conclusions Sleep quality in PsA patients has good correlation with quality of life. Disease duration, severity of pain, skin leisons and entesitis did not seem to interfere with sleep quality for PsA. Treatment strategies in PsA should includes not only arhritis and skin lesions but also sleep therapies to increase the quality of life of patients.

Objectives: This study aims to investigate the validity and reliability of the Turkish version of the Mini-Osteoarthritis Knee and Hip Quality of Life (Mini-OAKHQoL) scale developed to assess the quality of life (QoL) in patients with knee and/or hip osteoarthritis. Patients and methods: Between May 2018 and May 2020, a total of 83 patients (11 males, 72 females; mean age: 58.1±10.0 years; range, 39 to 81 years) with knee and/or hip osteoarthritis were included. Demographic, clinical, and survey data (Mini-OAKHQoL, Nottingham Health Profile, Short Form-36, Western Ontario and McMaster Universities Osteoarthritis Index, Lequesne Index, and Visual Analog Scale of pain intensity) were recorded. Missing data, floor effect, and ceiling effect were calculated. For reliability analysis, internal consistency and test-retest reliability were discovered. Face, content, convergent, and divergent validities were applied. Results: Among the patients, 52 (62.65%) had knee osteoarthritis, 26 (31.32%) had hip osteoarthritis, and five (6.02%) had both. Mini-OAKHQoL had a good face and content validity. The average item completion rate was 96.9%, with the time needed to perform was about 4 min. None of the subscales of Mini-OAKHQoL presented floor or ceiling effect, with a good range of responses. The Cronbach alpha coefficients and intraclass correlation coefficient (ICC) analysis of the subscales ranged from 0.927 to 0.676 and 0.987 to 0.843, respectively. Regarding convergent validity, the physical activities, mental health, and pain subscales of Mini-OAKHQoL had moderate to high correlations with the topic-related subset of the other QoL surveys. There were no or weak correlations between Mini-OAKHQoL and non-QoL parameters, indicating its divergent validity. Conclusion: The Turkish version of Mini-OAKHQoL is a valid, reliable, simple, practical, accurate, completable, comprehensive, and disease-specific self-report instrument to assess QoL in patients with knee and/or hip osteoarthritis.

Background The Duruöz Hand Index (DHI) [1] has 18 items of daily activities questions. It was developed to assess the functional disability of rheumatoid hand and cross validated for some other arthropaties of the hand (osteoarthritis, systemic sclerosis, carpal tunnel syndrome, stroke, flexor tendon rupture etc.). Objectives To assess the usefulness of the DHI to evaluate functional disability of hands in geriatri population. Methods Subjects aged more than 65 were recruited into the study. The local or systemic diseases which may affect directly the hand function were exclusion criteria. Demographic and functional characteristics of subjects were evaluated. The functional assessment was performed with DHI, Hand Functional Index (HFI), Health Assessment Questionnaire (HAQ), Purdue Pegboard (fingertip dexterity and hands coordination) and grip strength (JAMAR) and 3 kinds of pinch (tip, lateral, chuck) strengths (JAMAR). The DHI was correlated (Spearman’s correlation coefficient) with the other functional parameters to assess the convergent validity and with non-functional parameters to assess the divergent validity. p<0.05 was significant. Results Fifty patients (33 female) with mean age 72.6 (range: 65-90) were recruited. The average score of DHI was 16.32 (SD: 17.57) and 26.0% of patients had zero score (without disability). The DHI had not any significant relation with demographic data such as age, hand dominancy, alcohol consumption, smoking and DHI has poor or fair correlation with fatigue level and Pittsburg Sleep Quality Index (divergent validity). The DHI has significant and good correlation with Health Assessment Questionnaire (HAQ), Hand Functional Index, Purdue Pegboard scores, grip strength and 3 types of pinch strengths (convergent validity). The strongest relation of DHI is with HAQ (rho: 0.782; p<0.0001). Conclusions The DHI is practical scale and it is useful to assess the functional disability of hands accurately in geriatric population. References Duruöz MT et al.
