Recommendations of the Mexican College of Rheumatology for the management of psoriatic arthritis.

Unlabelled: Psoriatic arthritis is a chronic systemic inflammatory disease that affects the skin, musculoskeletal structures and other organs and systems compromising functionality, quality of life and reducing the life expectancy of patients. It is a complex disease that requires specialist and timely care and management. The alternatives for treating the manifestations of psoriatic arthritis have increased and the effect of the different agents on specific manifestations has been clarified in recent studies.

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.

Nevoid acanthosis nigricans: Report of four cases localized to the umbilicus.

Nevoid acanthosis nigricans is a rare, benign form of acanthosis nigricans. Of the 24 cases documented in the literature, only two are exclusively localized to the umbilicus. We present four cases of nevoid acanthosis nigricans localized to the umbilicus; in patients less than 25 years of age, with no known co-morbidities, three of whom were females.

A potential inflammatory role of IL-31 in psoriatic arthritis: A correlation with Th17 cytokine profile.

The goals of our study were to determine the possible association of interleukin (IL)-31 with Th17 cytokine profile in serum and to quantify retinoic acid-related orphan receptor C () mRNA expression in psoriatic arthritis (PsA) patients. This cross-sectional study was conducted in 50 patients with PsA and 30 control subjects (CS) matched by age and gender. The cytokine serum levels were quantified by magnetic bead-based assay using the Bio-Plex MAGPIX system, and mRNA expression was determined by quantitative polymerase chain reaction (qPCR).
