Tamay-Cach, O.L. Valenzuela-Limón, E.A. García-Montalvo, A. Hernández-ZavalaAbstractArsenic, a metalloid and naturally occurring element, is one of the most abundant elements in the earth's crust. Water is contaminated by arsenic through natural sources (underground water, minerals and geothermal processes) and anthropogenic sources such as mining, industrial processes, and the production and use of pesticides. Humans are exposed to arsenic mainly by drinking contaminated water, and secondarily through inhalation and skin contact. Arsenic exposure is associated with the development of vascular disease, including stroke, ischemic heart disease and peripheral vascular disease. Also, arsenic increases the risk of tumors of bladder, lungs, kidneys and liver, according to the International Agency for Research on Cancer and the Food and Drug Administration. Once ingested, an estimated 70–90% of inorganic arsenic is absorbed by the gastrointestinal tract and widely distributed through the blood to different organs, primarily to the liver, kidneys, lungs and bladder and secondarily to muscle and nerve tissue. Arsenic accumulates in the organs, especially in the liver. Its excretion mostly takes place through urination. The toxicokinetics of arsenic depend...

AbstractNeuropathic pain (NeP) is an intractable pain caused by a lesion or disease of the somatosensory nervous system. NeP is often challenging to manage because most of the mechanisms remain to be elucidated. Recent investigations in the field of autoimmune neurology have demonstrated that specific autoantibodies against antigens in the somatosensory pathway can cause NeP. Detection of pathogenic autoantibodies in NeP adds to the understanding of the mechanism of pain, which might aid in the development of novel immunotherapies. Therefore, it is necessary to explore novel NeP ‐related autoantibodies to improve the man...

This study evaluated the distribution of the crizotinib patient information brochure (PIB) in Europe and patient knowledge of the key messages in the PIB. A cross‐sectional survey was conducted in 10 European countries among pa tients who received crizotinib to ascertain whether each patient received and read the PIB, and his/her knowledge of its key messages on hepatotoxicity, interstitial lung disease/pneumonitis, QTc prolongation, bradycardia, and vision disorders. Of the 341 patients contacted, 40 responded (11.7%), an d 39 patients were eligible. A total of 77% of respondents acknowledged receiving the PIB, of which...
