Autoimmune liver diseases (AILD) are a group of immunologically induced hepatic disorders that can lead to liver cirrhosis and end-stage liver disease. Extra-hepatic involvement and association with rheumatic diseases (such as Sjögren's syndrome, systemic sclerosis and rheumatoid arthritis) are well known, whereas the coexistence of AILD with small-vessel vasculitis in the same patients have been only occasionally reported. In the present paper we report four such cases and an extensive review of the literature. Clinical features of autoimmune-liver diseases associated with small-vessel vasculitis are discussed, as well as possible common pathogenic pathways including HLA genomics, costimulatory molecules and autoantibodies. In conclusion, knowledge about this association can help physicians in recognising and treating an aggressive disease which could otherwise result in severe and multiple organ damage, compromising the overall prognosis and the indication to liver transplantation.

The activity of residual nuclides dictates the radiation fields in periodic inspections/repairs (maintenance periods) and dismantling operations (decommissioning phase) of accelerator facilities (i.e., medical, industrial, research) and nuclear reactors. Therefore, the correct prediction of the material activation allows for a more accurate planning of the activities, in line with the ALARA (As Low As Reasonably Achievable) principles. The scope of the present work is to show the results of a comparison between residual total specific activity versus a set of cooling time instants (from zero up to 10 years after irradiation) as obtained by two analytical (FISPACT and ANITA) and two Monte Carlo (FLUKA and PHITS) codes, making use of their default nuclear data libraries. A set of ~40 irradiating scenarios is considered, i.e. neutron and proton particles of different energies, ranging from zero to many hundreds MeV, impinging on pure elements or materials of standard composition typically used in industrial applications (namely, AISI SS316 and Portland concrete). In some cases, experimental results were also available for a more thorough benchmark.

OBJECTIVES: Fibromyalgia (FM) association with autoimmune diseases has been widely reported in literature. Coeliac disease (CD) is a small intestine immune-mediated disorder triggered by gluten ingestion in genetically predisposed patients. In recent years, the Internet and the non-medical press have reported a correlation between gluten-related disorders and fibromyalgia-like symptoms. The aim of our study was to verify a possible association between FM and CD, by assessing the prevalence of CD in a cohort of FM patients and vice versa. METHODS: 90 consecutive subjects from our Rheumatologic outpatient clinic who had been diagnosed with FM were serologically tested for CD and positive patients underwent esophagogastroduodenoscopy to obtain duodenal biopsies. A second group of 114 consecutive subjects from our Coeliac Disease outpatient clinic were investigated for the presence of FM-like symptoms through a questionnaire. Patients reporting chronic widespread pain were addressed to a rheumatologist for further evaluation. RESULTS: The overall prevalence of CD in our FM patients was identical to that expected in general population (around 1%). In our CD group 17 patients (14.9%) reported chronic widespread pain at the questionnaire and 13 (11.4%) satisfied ACR 1990 criteria for FM. Their symptoms had not been modified by GFD. CONCLUSIONS: A serological screening for CD is not recommended in FM patients but rather a case-finding strategy should be performed. At the same time, proposals of GFD in FM patients, in absence of a well-established diagnosis of CD, should be rigorously avoided.
