Assessment of rheumatoid arthritis patients' knowledge about foot problems related to their illness and foot care practice.

INTRODUCTION: Foot problems are very common in rheumatoid arthritis (RA). Podiatric intervention through therapeutic education of RA patients on the different potential foot problems could improve patients' knowledge and management of their foot problems. This study aimed to evaluate the knowledge of RA patients on podiatric problems related to their illness and foot care practices. METHODS: This was a cross-sectional study including patients diagnosed with RA and aged older than 18 years. Sociodemographic data, disease characteristics, and therapeutic data were collected. RA foot problems knowledge and foot care practice were assessed using a questionnaire combining questions developed from the literature search and a pretested validated questionnaire. RESULTS: Overall, 103 patients were included of whom 94 were female. The mean age was 56 years (±10 years) and the mean disease duration was 15 years (±10 years). Over 77% of patients reported never having received foot-health-related education. With regard to their knowledge about RA foot involvement, patients were aware that RA can affect the feet similarly to the hands (83%), lead to deformation of the foot (86%), lead to walking difficulties and falling (68%), and produce skin lesions of the foot (31%). Regarding participant's knowledge of appropriate footwear, 65% agreed that it would be beneficial to wear quality standard sports shoes. However, less than one-third of patients know the podiatrist's skills. CONCLUSION: Our study showed an awareness of the repercussions of RA on feet but a lack of knowledge on proper foot care, thus identifying a need for foot health therapeutic education.

Burden of disease, pain catastrophizing, and central sensitization in relation to work-related issues in young spondyloarthritis patients.

Introduction: Spondyloarthritis (SpA) is a common rheumatic inflammatory disease and can impact patients' work productivity. We aimed to evaluate the impact of pain catastrophizing and central sensitization on work outcomes in young SpA patients and determine the predictive factors of work productivity loss. Material and methods: We performed a cross-sectional study over 6 months. We included patients aged between 18 and 50 years old, diagnosed with axial or peripheral SpA. Pain catastrophizing and central sensitization were assessed using the Pain Catastrophizing Scale (PCS) and Central Sensitization Inventory (CSI) questionnaire, respectively. Impact of SpA on work productivity and activity impairment during and outside of work was measured with the Work Productivity and Activity Impairment Questionnaire (WPAI: Spondyloarthritis). Results: A total of 72 patients were enrolled, with a median age of 39 years (28.3-46), 65.3% men, and 54.4% working patients. Median scores of activity impairment outside of work, and work productivity loss were 50% (40-70), and 50% (40-60), respectively. Median absenteeism and presenteeism scores were 0% (IQR 0-7), and 100% (IQR 86.5-100), respectively. Regarding work-related outcomes: activity impairment was positively correlated with CSI and PCS; presenteeism was significantly associated with male sex (p = 0.009); and work productivity loss was positively associated with anxiety, depression, and poor quality of life. Multivariate regression analysis identified predictive factors of work productivity loss: male sex, poor quality of life, and prolonged morning stiffness. Conclusions: Assessment of the impact of pain catastrophizing and central sensitization on work-related outcomes in patients with SpA is important to understand the burden of illness and to identify early those in need of interventions in clinical practice.

Ultrasound Assessment of Psoriatic Arthritis Patients With Clinically Normal Nails and Evaluation of its Correlation with the Disease Activity: A Case-Control Study.

OBJECTIVES: Nail unit is one of the targets of ultrasound (US) assessment. We aimed to compare ultrasound parameters of clinically normal nail unit in psoriatic arthritis (PsA) patients with healthy controls (HC) and evaluate their correlations with disease activity. METHODS: This was a cross-sectional study including patients with PsA and matched HC. Tender (TJC) and swollen joint count (SJC), Psoriasis Area and Severity Index (PASI), and Disease Activity in Psoriatic Arthritis (DAPSA) were collected in PsA patients. Patients underwent US assessment of fingernails with a study of morphological changes and measurement of the thickness of nail bed (NBT), nail plate (NPT), and adjacent skin (ST). Correlation between nail unit parameters and disease activity was studied. RESULTS: We evaluated 22 PsA patients (219 nails) and 21 HC (210 nails). Mean DAPSA was 21.56 ± 14.36 and mean PASI was 2.19 ± 3.8. PsA patients had more US morphological changes than HC (16.89 vs 3.33%, P = .03). NPT comparison between identical fingernails of PsA and HC did not reveal significant difference. However, NBT was significantly higher in HC (1.77 vs 2.07 mm, P = .027) as well as ST (2.26 vs 2.59 mm, P = .003). TJC and ST were positively correlated (r = .46, P = .03). No correlation was noted between disease activity scores and NPT, NBT, or ST in PsA patients. In biologic parameters, ESR was negatively correlated with ST (r = -.41, P = .05). CONCLUSIONS: Nail bed and adjacent skin US morphological changes were contributive to distinguish psoriatic from healthy nails. Adjacent skin thickness measurement was positively correlated with TJC and ESR, suggesting that it could be used as an indicator of disease activity in PsA.

Acroparesthesias: An Overview.

Acroparesthesia is a symptom characterized by a subjective sensation, such as numbness, tingling, prickling, and reduced sensation, affecting the extremities (fingers and toes). Despite its frequency, data regarding its diagnostic approach and management are scarce. The etiological diagnosis of acroparesthesia is sometimes challenging since it can be due to abnormality anywhere along the sensory pathway from the peripheral nervous system to the cerebral cortex. Acroparesthesia can reveal several diseases. It can be associated with rheumatic complaints such as arthritis or myalgia. Further cautions are required when paresthesia is acute (within days) in onset, rapidly progressive, severe, asymmetric, proximal, multifocal, or associated with predominant motor signs (limb weakness) or severe dysautonomia. Acroparesthesia may reveal Guillain-Barré syndrome or vasculitis, requiring rapid management. Acroparesthesia is a predominant symptom of polyneuropathy, typically distal and symmetric, often due to diabetes. However, it can occur in other diseases such as vitamin B12 deficiency, monoclonal gammopathy of undetermined significance, or Fabry's disease. Mononeuropathy, mainly carpal tunnel syndrome, remains the most common cause of acroparesthesia. Ultrasonography contributes to the diagnosis of nerve entrapment neuropathy by showing nerve enlargement, hypoechogenic nerve, and intraneural vascularity. Besides, it can reveal its cause, such as space-occupying lesions, anatomical nerve variations, or anomalous muscle. Ultrasonography is also helpful for entrapment neuropathy treatment, such as ultrasound-guided steroid injection or carpal tunnel release. The management of acroparesthesia depends on its causes. This article aimed to review and summarize current knowledge on acroparesthesia and its causes. We also propose an algorithm for the management of acroparesthesia.

Foot function in rheumatoid arthritis: Correlation between the Rheumatoid and Arthritis Outcome Score and performance-based physical tests.

BACKGROUND: Foot function is usually assessed using self-reported outcome measures which remain subjective in patients with rheumatoid arthritis (RA). Physical performance tests were recommended for functional assessment in lower limb osteoarthritis. However, foot function assessment's guidelines in RA are lacking. We aimed to investigate the correlation between a self-reported outcome measure and two performance-based physical tests for assessing foot function in RA patients. METHODS: A cross-sectional study was performed over 7 months' period including RA patients. We used Rheumatoid and Arthritis Outcome score (RAOS) as a self-reported functional tool. Physical performance tests were 4-min walk test (4-MWT) and Timed up and go test (TUGT). RESULTS: Fifty RA patients were included with 96% females and a mean age of 54.7 ± 10.4 years. Foot involvement occurred since the diagnosis of RA in 36% of patients. Foot pain was reported by 68% of patients (48% forefoot), and foot stiffness in 46% of patients. Skin lesions of the feet were found in 78% of patients, 90% had foot deformities and 56% had inflammatory disorders of feet. Radiographic lesions were found in 94% of patients. The most impaired RAOS subscales were Sports and Recreation and Quality of life. Poor physical-based performance was found in 34% of RA patients according to 4-MWT, in 42% of RA patients according TUGT, and in 46% of patients based on at least one performance test. RAOS was negatively correlated to the 4-MWT and positively correlated in the subscales pain, other symptoms, activities of daily living, and Sport/Rec of the RAOS. Poor performance-based physical tests were significantly associated with advanced age, sedentary lifestyle, higher disease activity score and impaired functional status. Foot-related parameters significantly associated with poor performance-based physical tests were: foot pain, foot deformity and inflammatory disorders. Multivariate analysis identified foot deformities and higher functional impairment as predictive factors for lower gait speed (4-MWT) and older age and higher functional impairment for higher duration of TUGT. CONCLUSION: RAOS was significantly associated with performance-based physical function. In the era of connected technologies, these results encourage the regular assessment of rheumatoid foot function by the RAOS score through a connected programme using wearable trackers.

Cutaneous and rheumatological manifestations of reactive arthritis: A case report.

Reactive arthritis is a rare form of spondyloarthropathies occurring after genital or enteric infection. It is most often self-limited but can progress to chronic spondylarthritis. We report the case of a 30-year-old man who presented with acute arthritis occurring 2 months after an episode of urethral discharge. Physical examination revealed polyarthritis, dactylitis, sacroiliac joint involvement, and plantar papulosquamous plaques. The human leukocyte antigen B27 was positive. Detection of Chlamydia trachomatis and Gonococcus in the first catch urine specimen was negative. Hepatitis B and C, Chlamydia trachomatis, human immunodeficiency virus, and syphilis serologic test results were negative. Pelvic magnetic resonance imaging revealed left sacroiliitis. The patient was treated with antibiotics, diclofenac, and sulfasalazine. After 6 months of follow-up, a significant clinical improvement was obtained without remission, suggesting an evolution to chronic spondylarthritis. Diagnosis of Reactive arthritis is difficult since microbiologic examinations are commonly negative. This disease should be considered in patients with rheumatologic manifestations occurring after a urogenital or enteric infection, mainly when associated with skin manifestations and human leukocyte antigen B27.

Acute arthritis revealing Hashimoto's thyroiditis.

Rheumatic manifestations can reveal hypothyroidism, such as arthritis and nonspecific musculoskeletal symptoms. We report herein the case of an acute polyarthritis revealing Hashimoto's thyroiditis (HT). Hormone replacement therapy leads to the resolution of arthritis related to HT, suggesting the role of thyroid hormone in the pathogenesis of arthritis.

Fortuitous discovery of isolated tuberculosis of the tenth and eleventh costotransverse joints: A case report.

Involvement of posterior elements of the spine in spinal tuberculosis is rare. We report a case of a 56-year-old woman who presented with asymptomatic tuberculosis of the tenth and eleventh costotransverse joints. The latter was discovered with a CT scan made to look for a pulmonary embolism. Magnetic Resonance Imaging (MRI) showed liquid in the costotransverse joints with a paravertebral abscess. The patient was managed conservatively. Although rare, posterior tuberculosis of the spine should be known by spine surgeons. MRI is the key to the diagnosis. Conservative treatment is the standard treatment, and surgery is reserved for patients with neurological deficit.
