This paper aims to study the prevalence of total knee and hip replacements in Greek patients with rheumatoid arthritis (RA) and to identify possible predictive factors for future total hip or knee replacement. ⋯ The identification of factors associated with total joint hip or knee replacement can improve pharmacological treatment to maintain function and prevent destruction of the affected joints. Longer disease duration and inadequate response to treatment after the first year of follow-up increases the likelihood ratio for total joint replacement during the course of disease in Greek RA patients.

Case Reports
Stiff skin syndrome and myeloma successfully treated with autologous haematopoietic stem cell transplantation (HSCT).
Stiff skin syndrome (SSS) is a rare scleroderma-like syndrome characterised by stone hard skin, joint limitation and progressive restriction of chest that may lead to death. We describe the efficacy of haematopoietic autologous stem cell transplantation (HSCT) in a case of SSS secondary to a smouldering myeloma (SM), with severe joint disability, lung interstitial disease and oesophageal dysfunction. The patient was evaluated at 1, 12 and 18 months after HSCT, clinically (joint motility, HAQ and NYHA for dyspnoea) and instrumentally (DLCO, chest HRCT, oesophagus x-ray). After 18 months since HSCT, we observed a high improvement, contemporaneously to SM remission, of HAQ, joint motility, lung (at DLCO and HRCT) and oesophageal abnormalities.

The risk of activation of latent tuberculosis infection (LTBI) is increased in patients treated with anti-TNF-α drugs. Tuberculin skin test (TST) and Quantiferon-TB Gold test (QFT) are used to detect LTBI before and during anti-TNF-α treatment. We describe here a relation of these tests at various timepoints and also longitudinal QFT data. ⋯ Poor correlation between the QFT and TST renders the TST non-specific for LTBI. QFT is more specific to detect LTBI and conversion to a positive result may predict active TB. An increase in IFN-γ production in response to mycobacterial antigens is seen when the TST is performed before the QFT. Mitogen-induced IFN-γ production increases after initiation of anti-TNF-α therapy.

The aim of this study was to evaluate the aetiology of 'unexplained' cytopenias in patients with autoimmune disorders, as well as to identify parameters that should alert clinicians to the need for bone marrow examination. ⋯ Clonal haematologic disorders and toxicity are frequent findings in patients with autoimmunity referred for haematologic consultation, owing to otherwise unexplained cytopenias. Patients with high serum iron, high MCV and presence of serum monoclonal band should undergo bone marrow examination to exclude haematologic malignancy or bone marrow toxicity.

Randomized Controlled Trial
The effect of dietary glutamate on fibromyalgia and irritable bowel symptoms.
To examine the effects of a challenge with monosodium glutamate (MSG) as compared to placebo on the symptoms of fibromyalgia (FM), in participants who initially experienced >30% remission of symptoms on an excitotoxin elimination diet. ⋯ These findings suggest that dietary glutamate may be contributing to FM symptoms in some patients. Future research on the role of dietary excitotoxins in FM is warranted.
