ReviewAre psoriasis and psoriatic arthritis the same disease? The IL-23/IL-17 axis data.
Psoriatic arthritis (PsA) is a psoriasis (Ps)-associated inflammatory joint disease that affects peripheral joints, entheses, spine, and eyes. PsA and Ps are likely to be the same disease. PsA develops in nearly 70% of patients with Ps, and the hallmark of the disease is bone erosions and bone formation. ⋯ IL-22 is highly expressed in skin lesions and entheses, not peripheral joints, and cause bone formation. Finally, mannan from baker's yeast caused PsA-like arthritis and Ps-like skin lesions that were blocked by IL-17 treatment. These data suggest that PsA and Ps are likely to be the same disease exhibiting different manifestations depending on the local cytokine production.

ReviewThe clinical relevance of complex regional pain syndrome type I: The Emperor's New Clothes.
The management of patients with chronic pain is a nearly daily challenge to rheumatologists, neurologists, orthopedic surgeons, pain specialists and indeed a issue in nearly every clinical practice. Among the myriad of causes of pain are often included a unique syndrome, generally referred to as complex regional pain syndrome type I (CRPS). Unfortunately CRPS I has become a catch all phase and there are serious questions on whether it exists at all; this has led to an extraordinary number of poorly defined diagnostic criteria. ⋯ This observation is underscored by the diversity of responses among "CRPS I" patients to essentially all treatment modalities. It has even led to the concept that the signs and symptoms of CRPS can spread throughout the body, as if it is an infectious disease, without any medical plausible explanation. If true progress is to be made in helping patients with pain, it will require entirely new and different concepts and abandoning CRPS I as a legitimate diagnosis.

Multicenter StudyInterstitial lung disease in primary Sjögren's syndrome.
Interstitial lung disease (ILD) has been reported in 3 to 11% of patients with primary Sjögren's syndrome (pSS). The aims of this retrospective multicenter study were to: 1) analyze characteristics and outcome of ILD in pSS; and 2) evaluate predictive factors associated with ILD onset and deterioration. Twenty-one of 263 patients with pSS (8%) developed ILD. ⋯ Factors associated with ILD deterioration were: older age (p=0.038) and esophageal involvement (p=0.038). Thus, this study underscores the poor outcome of ILD during pSS; thus, systematic screening of pulmonary involvement is required in pSS patients, resulting in both diagnosis and management at early stage of ILD. We also suggest that patients presenting predictive factors of ILD deterioration may need a closer follow-up and a more aggressive therapy.

Revisiting the systemic vasculitis in eosinophilic granulomatosis with polyangiitis (Churg-Strauss): A study of 157 patients by the Groupe d'Etudes et de Recherche sur les Maladies Orphelines Pulmonaires and the European Respiratory Society Taskforce on eosinophilic granulomatosis with polyangiitis (Churg-Strauss).
To guide nosology and classification of patients with eosinophilic granulomatosis with polyangiitis (EGPA) based on phenotype and presence or absence of ANCA. ⋯ We suggest a revised nomenclature and definition for EGPA and a new proposed entity referred to as hypereosinophilic asthma with systemic (non vasculitic) manifestations.
