SER recommendations on treatment of refractory Behçet's syndrome.

Objective: To develop multidisciplinary recommendations based on available evidence and expert consensus for the therapeutic management of patients with refractory Behçet's syndrome (BS) (difficult to treat, severe resistant, severe relapse) to conventional treatment.

Methods: A group of experts identified clinical research questions relevant to the objective of the document. These questions were reformulated in PICO format (patient, intervention, comparison and outcome).

SER recommendations on the use of biological drugs in primary Sjögren's syndrome.

Objective: To formulate SER recommendations for the use of biological agents in primary Sjögren's syndrome (pSS).

Methods: Relevant clinical research questions were identified on the use of biological agents in pSS. The clinical questions were reformulated into 4PICO questions.

Adult-onset Still's disease with atypical cutaneous manifestations.

The diagnosis of adult-onset Still's disease (AOSD) can be very difficult. There are no specific tests available, and diagnosis is usually based on a symptom complex and the well-described typical evanescent rash seen in the majority of patients. However, in recent years, other atypical cutaneous manifestations of AOSD have been reported.

[Treating undifferentiated arthritis. What, when, how and how long?].

With the establishment of early arthritis clinics, patients can now be increasingly attended early in the course of their disease. This means that a significant proportion of these patients cannot be classified into a specific diagnosis using the traditional American College of Rheumatology (ACR) classification criteria. In these patients with undifferentiated arthritis (UA), even more important than assigning a diagnosis is the need to distinguish between patients who will develop a persistent and/or erosive disease and will be candidates for prompt treatment with disease-modifying antirheumatic drugs (DMARD), and patients in whom the disease is self limiting.
