[What rheumatologists can learn from ophthalmologists]. / Was der Rheumatologe vom Augenarzt lernen kann.

Intraocular inflammation with the imprecise and broad umbrella term "uveitis" is a diagnostic and therapeutic challenge in ophthalmology. Uveitis is one of the most common causes of blindness worldwide and due to the associated costs is comparable to diabetic retinopathy. Patients can be affected by uveitis at any age. Any part of the eye may be affected. The symptoms range from complete absence of symptoms, through all types of vision deterioration up to a red and even very painful eye. Uveitis can be strictly unilateral (also alternating from the left to the right eye) or bilateral with a relapsing or chronic course. The transitions are smooth and the differential diagnoses are very broad. In addition to infectious forms and ocular syndromes restricted to the eye, it also includes those with extraocular systemic diseases, such as ankylosing spondylitis or sarcoidosis. All commonly administered immunosuppressive treatment strategies in rheumatology can be used for non-infectious forms in addition to local and regional forms of treatment. The diagnostic and therapeutic impulses of this interdisciplinary interface between rheumatology and ophthalmology is discussed in more detail in this article.

Disease evolution in systemic juvenile idiopathic arthritis: an international, observational cohort study through JIRcohort.

BACKGROUND: Systemic juvenile idiopathic arthritis (systemic JIA) is a severe disease with both systemic and joint inflammation. This study aims to identify predictors of disease evolution within the systemic JIA population enrolled in the Juvenile Inflammatory Rheumatism cohort (JIRcohort). METHODS: Observational patient cohort study with 201 recruited children from 4 countries (3 European, 1 North Africa) from 2005 until 2019, using retrospectively (2005-2015) and prospectively (2015-2019) routine care collected data. RESULTS: Sixty-five patients with complete follow-up data for 24 months after first diagnosis were classified as monophasic (n = 23), polyphasic (n = 6) or persistent group (n = 36) corresponding to their evolution (unique flare, recurrent flares, or persistent disease activity respectively). The patients of the persistent group were more likely to have an earlier disease onset, before the age of 6 (OR 2.57, 95%-CI 0.70-9.46), persistence of arthritis at 12-months post-diagnosis (OR 4.45, 95%-CI 0.58-34.20) and higher use of synthetic DMARD (sDMARD, OR 5.28, 95%-CI 1.39-20.01). Other variables like global assessment by physician and by patient and C Reactive Protein levels at 12-months post-diagnosis were assessed but without any predictive value after adjusting for confounding factors. CONCLUSIONS: Our results suggest that the earlier disease onset, the persistence of arthritis throughout the first year of disease evolution and the need of sDMARD might predict a persistent disease course.

Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome in childhood: a report of ten cases and review of the literature.

UNLABELLED: Chronic recurrent multifocal osteomyelitis is a rare chronic inflammatory musculoskeletal process observed in children and young adults. Recently, the acronym SAPHO syndrome (for synovitis, acne, pustulosis, hyperostosis, osteitis) was coined to emphasise the association between osteo-articular inflammations and different skin abnormalities which are aseptic and filled with neutrophils. In adults, chronic recurrent multifocal osteomyelitis is now a classical manifestation of SAPHO syndrome. Chronic skin disorders were seen in eight of ten children on follow-up at the University Children's Hospitals in Bern and Zurich and in 61 of 260 paediatric cases reported in the literature. The different skin lesions were palmoplantar pustulosis (n = 40), non-palmoplantar pustulosis (n = 6), psoriasis vulgaris (n = 16) or severe acne (n = 4). More rarely Sweet syndrome (n = 2) or pyoderma gangrenosum (n = 1) were reported. CONCLUSION: The synovitis, acne, pustulosis, hyperostosis, osteitis syndrome is pertinent even in paediatrics since skin involvement is frequent.
