BackgroundTotal Knee Arthroplasty (TKA) is offered to patients with knee osteoarthritis (OA) in the oil-rich countries in the Gulf region without adequate understanding of their perceptions, preferences or pain experiences. This study aimed to explore the pain experience and mobility limitation as well as the patient’s decision making process to undertake TKA among women with knee pain in the waiting list for surgery.MethodsFive focus group discussions were conducted comprised of 39 women with severe knee OA from the waiting list for TKA in the only orthopaedic hospital in Kuwait. Discussions were recorded, transcribed and coded for themes to identify the factors considered to be important in decision-making for TKA.ResultsExperiencing knee pain was central to daily living and affected patients and their families. Mobility limitation was shaped by a strong sense of expected obligation to take care of the family. Two major sources of TKA delay were identified; one was due to late clinical advice to undergo TKA which was the result of receiving several consultations from different clinicians each of whom tried the medical management for OA. The second delay occurred after the clinical advice for TKA and was mainly due to ambivalence of patients because of fear of the operation and the lack of information about TKA that resulted in unclear expectations of the surgery.ConclusionsBoth verbal and written information about TKA should be provided as part of preoperative rehabilitation. This is critical to improve doctor-patient interactions and facilitate informed decision about the procedure and thus achieve patient-centered healthcare.

Objective: We aimed to assess the efficacy of short-term oral vitamin D supplementation on peripheral neuropathy in patients with type 2 diabetes. Materials and Methods: This prospective, placebo-controlled trial included 112 type 2 diabetic patients with diabetic peripheral neuropathy (DPN) and vitamin D [25(OH)D] deficiency. Patients were sequentially assigned to a treatment group (n = 57) and a placebo group (n = 55). DPN was assessed using a neuropathy symptom score (NSS), a neuropathy disability score (NDS) and a nerve conduction study (NCS). Vitamin D status was determined by measuring the serum total 25(OH)D concentration. Patients received either oral vitamin D₃ capsules or starch capsules once weekly for 8 weeks. The primary outcome was changes in NSS and NDS from baseline. The secondary outcome was changes in the NCS result. Results: Serum 25(OH)D concentrations significantly improved after oral vitamin D supplementation in the treatment group when compared to the placebo group (32.8 ± 23.7 vs. 1.1 ± 3.6, p < 0.0001). Similarly, the improvement in NSS values was significantly greater in the treatment group than in the placebo group (-1.49 ± 1.37 vs. -0.20 ± 0.59, p < 0.001). No improvement was observed for NDS and NCS between the 2 groups after treatment. Conclusion: Short-term oral vitamin D₃ supplementation improved vitamin D status and the symptoms of neuropathy in patients with type 2 diabetes.

BACKGROUNDThe WHO-ILAR Community Oriented Program for Control of Rheumatic Diseases (COPCORD) primarily aims to estimate the burden of musculoskeletal symptoms/disorders. We estimated the incidence of musculoskeletal pain in the first community-based COPCORD study in Kuwait.SUBJECTS AND METHODSThe validated Arabic version of the WHO-ILAR COPCORD Core Questionnaire was used in a survey of 2500 randomly selected Kuwaiti households to assess the frequency of musculoskeletal pain, disability, and health-seeking behavior in adult Kuwaitis. Those subjects reporting no musculoskeletal pain were identified and followed-up for a period of one year by contacting them every 2 weeks. Once a respondent reported pain, an appointment to report to hospital was offered and the subject was examined by a rheumatologist using American College of Rheumatology (ACR) criteria.RESULTSOf 5159 adults who were non-complainers in an earlier prevalence phase of the study, 3341 responded to phone calls (response rate of 65%). The incidence of musculoskeletal pain was 6.6% (95%CI, 3.4%-9.7%). Age- and sex-adjusted incidence rates were 7.2% (95%CI, 3.4%-10.5%) for females and 6.1% (95%CI, 3.1%-9.2%) for males. The incidence rate increased with increasing age, body mass index, and with being married. The common sites of pain were knee, low back and shoulder.CONCLUSIONThe incidence of musculoskeletal pain among Kuwaiti adults is reported for the first time. Further studies adopting the same instrument in other communities are warranted to compare with our findings.

Objective: To determine the life and point prevalence rates and study the characteristics of work-related and non-work-related low back pain (LBP) among physical therapists in Kuwait and its effect on their regular activities. Subjects and Methods: A specially designed self-administered questionnaire was distributed to 143 physical therapists in Kuwait. The questionnaire included demographic data, history and characteristics of LBP before and after working as a physical therapist, the effect of LBP on regular activities and current LBP. A visual analogue scale was used to score the intensity of the pain. Results: One hundred (70%) of the 143 physical therapists completed the questionnaire; mean age and standard deviation of the respondents were 35.9 ± 8.45 years. The lifetime prevalence of work-related LBP was 70% (61.8% in males and 74.2% in females) and the point (current) prevalence rate was 57% (31.6% in males and 68.4% in females). All the 100 therapists were college graduates who worked full-time and 82% were employed in general hospitals and rehabilitation centers. The most common areas of specialty were orthopedics (32%) and neurology (23%). Fifty percent reported that LBP affected their regular activities, 28.6% reported limitation due to pain and 11.4% changed their work settings because of LBP. The main site of pain was at low back and buttocks. Pain intensity was scored similarly among male and female physical therapists. Conclusion: Work-related and point prevalence rates of LBP among physical therapists in Kuwait are high and affect their daily activities, necessitating changes in work settings.

Low back pain (LBP) is a common medical problem. Interaction between genetic and environmental factors predisposes individuals to LBP even at an early age. Inflammatory back pain or spondylarthropathies include ankylosing spondylitis (AS), psoriatic arthritis (PSA), reactive arthritis enteropathic and undifferentiated arthropathies. Angiotensin-converting enzyme (ACE) plays an important role in circulatory homeostasis, physiology of vasculature and inflammation. The insertion-deletion (I/D) polymorphism of the ACE gene has been shown to determine the plasma and tissue levels of ACE especially in the synovial fluid. The aim of this study was to investigate an association between ACE gene I/D polymorphism and inflammatory back pain (spondylarthropathies) secondary to ankylosing spondylitis (AS), psoriatic arthritis, inflammatory bowel disease and undifferentiated spondylarthropathies. The prevalence of ACE gene I/D polymorphism genotypes was determined in 63 patients with inflammatory back pain by polymerase chain reaction (PCR) and compared with that in 111 healthy controls. Of the 63 patients studied, 45 (71.4%) were with AS, 13 (20.6%) were with PSA, 4 (6.3%) were with reactive arthropathy and 1 (1.6%) manifested undifferentiated arthropathy. There were 43 males and 20 females. Mean age of patients was 39.0+/-11.36 years, age at onset of spondylarthropathy was 27.7+/-7.49 years and disease duration was 10.3+/-7.74 months. The controls were selected to match with the patients group in terms of gender ratio, age and ethnicity. The ACE gene polymorphism showed an overall significant difference between patients and controls (p=0.050). When the ID and II genotype frequency was combined and compared with that for DD genotype amongst patient and control groups, a considerably higher incidence was detected for ID and II genotypes than the DD genotype in spondylarthropathy patients compared to that in the controls (p=0.036). This study showed a significant association of the I-allele of ACE gene I/D polymorphism with spondylarthropathy in Kuwaiti Arabs.

The present study describes the clinical characteristics of patients with systemic lupus erythematosus (SLE), from the rheumatology service of the two main teaching hospitals in Kuwait. It was a retrospective-cum-prospective clinical study of 108 SLE patients. There were 98 females and 10 males, with a median age of 31.5y. Kuwaitis constituted 69%, while 31% were expatriates. The mean disease duration was 62 months. The main clinical features were: musculoskeletal involvement (87%), photosensitivity (48%), malar rash (43%), discoid lesions (10%), oral ulcers (33%), vasculitic skin lesions (10%), haematological features (53%), constitutional symptoms (51.4%), neuropsychiatric manifestations (23%), renal involvement (37%), serositis (29%), clinical manifestations of antiphospholipid syndrome (21%), cardiac involvement (10%) and pulmonary manifestations (19%). In conclusion, the clinical features of SLE in Kuwait were similar to most major studies from developed countries. Main differences included prominent haematological and mucocutaneous manifestations and possibly a low prevalence of anti-Sm antibodies. Whether these differences are due to the environment or genetic factors, remains to be studied.
