Psoriatic arthritis in patients with psoriasis: A clinical-epidemiological study at a dermatology center in western Mexico.

Background/objective: Psoriatic arthritis (PsA) is a chronic inflammatory illness. Approximately, 15% of psoriasis patients have undiagnosed PsA. In Mexico, we found no related studies.

Catastrophic health expenses and impoverishment of households of patients with rheumatoid arthritis.

Background: The cost of certain diseases may lead to catastrophic expenses and impoverishment of households without full financial support by the state and other organizations.

Objective: To determine the socioeconomic impact of the rheumatoid arthritis (RA) cost in the context of catastrophic expenses and impoverishment.

Patients And Methods: This is a cohort-nested cross-sectional multicenter study on the cost of RA in Mexican households with partial, full, or private health care coverage.

[Appropriate use of non-steroidal anti-inflammatory drugs in rheumatology: guidelines from the Spanish Society of Rheumatology and the Mexican College of Rheumatology].

Objective: To develop guidelines for the appropriate use of NSAIDs in rheumatology.

[Cardiovascular risk of cyclooxygenase selective inhibitors].

It has been estimated that 30 million people worldwide take an nonsteroidal antiinflammatory drug (NSAID) daily. The main clinical objectives of these drugs are both to reduce joint pain and to improve joint function. However, gastrointestinal adverse events lead to the development of cyclooxygenase selective inhibitors (COXIB) with a better gastrointestinal safety profile.

[Social costs of the most common inflammatory rheumatic diseases in Mexico from the patient's perspective].

Objective: To estimate the social costs of rheumatoid arthritis (RA), ankylosing spondylitis (AS), and gout from the patient's perspective.

Methods: We carried out a cross-sectional analysis of the cost and resource utilization of 690 RA, AS, and gout patients from 10 medical centers and private facilities in five cities of Mexico. The information was obtained from the baseline of a dynamic cohort.

Validation of the Health Assessment Questionnaire disability index in patients with gout.

Objective: To assess the psychometric properties of the Health Assessment Questionnaire (HAQ) disability index (DI) in patients with gout.

Methods: This study was conducted in a multicenter cohort of patients with gout whose data were collected at baseline (time 0) and 6 months later (time 6). Reliability was assessed by test-retest reliability (intraclass correlation coefficient [ICC]) and internal consistency (Cronbach's alpha coefficient).
