Cryopyrinopathies are a subgroup of autoinflammatory syndromes. Most cases have mutations in the CIAS1/NLRL3 gene, encoding the cryopyrin/NLRP3 protein. Cryopyrin, together with other proteins, is involved in the assembly of the cryopyrin/NLRP3 inflammasome. ⋯ FCAS results in cold-induced cytokine dysregulation and systemic inflammation. Symptoms can be treated, using IL-1β antagonists. Further research is warranted, particularly in order to investigate pathophysiological mechanisms in "mutation negative" individuals.

It is recommended to evaluate the presence of latent tuberculosis infection (LTBI) prior to the use of antitumor necrosis factor α. The aim of this study is to assess the presence of LTBI in patients with rheumatic diseases undergoing treatment with infliximab in an endemic area for tuberculosis (TB). LTBI was searched through the contact history, chest X-ray and tuberculin skin test with purified protein derivative (PPD) ≥5 mm. ⋯ No significant difference between the reactivity of the PPD and the use of immunosuppressive drugs (P = 0.81) is observed. The immunoprophylaxis with INH showed an efficacy of 95% (20/21); three (1.9%) patients developed active TB (spondylodiscitis, meningitis and lymphadenopathy) after the use of infliximab, reaffirming extrapulmonary involvement. These results suggest that PPD has a low sensitivity for detection of LTBI in RA and that the previous use of immunosuppressive drugs does not affect the response to PPD.

Case Reports
Posterior reversible encephalopathy syndrome in a patient with ANCA-associated vasculitis.
Posterior reversible encephalopathy syndrome (PRES) is a clinical syndrome that manifests with the onset of headache, confusion or decreased level of consciousness, visual changes, and seizures in conjunction with the typical neuroimaging features of posterior cerebral white matter changes, which are usually reversible. This syndrome has been associated with hypertension, eclampsia, renal insufficiency, immunosuppressive drugs, and connective-tissue diseases. To our knowledge, only four cases of PRES associated with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis have been reported in the literature. Here, we present a patient with ANCA-associated vasculitis complicated by PRES.

Randomized Controlled Trial Comparative Study
The effect of oral and parenteral vitamin D supplementation in the elderly: a prospective, double-blinded, randomized, placebo-controlled study.
Hypovitaminosis D in the elderly causes falls and fractures as a result of impaired neuromuscular functions and also may be a reason for nonspecific musculosceletal pain. The aim of this study is to investigate the benefits of a single dose per os or parenterally administrated vitamin D on increasing the quality of life and functional mobility and decreasing the pain in the elderly. The community-dwelling elderly subjects over 65 years age were included in the study. ⋯ When the pain, the functional mobility, and the quality of life were evaluated, in the first group, the TUG (P = 0.0001) and the VAS (P = 0.0001) decreased significantly, whereas the SF-36 subtitles: physical functioning (P = 0.0001), role physical (0.006), bodily pain (P = 0.0001), general health (P = 0.007), social functioning (P = 0.05), and mental health (P = 0.048) increased significantly. In group two, the VAS (P = 0.001) decreased, the role physical (P = 0.009), and role emotional (P = 0.034) increased significantly; In group three, the TUG (P = 0.0001) and the VAS (P = 0.002) decreased, whereas the physical function (P = 0.0001) and role physical (0.001) increased significantly; In group four, the VAS (P = 0.007) decreased significantly. The megadose vitamin D administration increases quality of life, decreases pain, and improves functional mobility via po or im route in the elderly.

Review Meta Analysis
Cyclophosphamide for scleroderma lung disease: a systematic review and meta-analysis.
To assess the effectiveness of cyclophosphamide in the management of scleroderma-related interstitial lung disease (ILD). In this systematic review study, the primary outcome measures were change in forced vital capacity (FVC) and diffusing capacity of the lung for carbon monoxide (D(L)CO) of the patients after 6 and 12 months. To assess the effect of cyclophosphamide on early stage of ILD, alveolitis, in SSc patients, we selected the studies that used the BAL findings or HRCT or recent deterioration of PFT with minimal chest X-ray finding in early stage of disease as diagnosis of alveolitis. ⋯ The summary WMD (random effects) was 2.45 (95% CI, 0.760-4.149 P = 0.005), which means that cyclophosphamide was able to prevent deterioration of FVC after 12 months. In pooled data of 13 studies, about DLCO after 12 months WMD (random effects) was 2.003 2.96 (95% CI, -0.228 to 6.159 P = 0.069), which means that cyclophosphamide was not able to prevent deterioration of D(L)CO after 12 months. If we considered clinically sensible improvement as absolute value ≥10% in DLCO and VC, then result of treatment with cyclophosphamide treatment in scleroderma patients with ILD was not significant.
