Disulfiram and calcium carbimide are two alcohol deterrants widely used in alcoholism treatment, however, there exist great concerns over their safety. Reports on hepatotoxicity, mainly related to disulfiram therapy, have been published. The hepatotoxic potential of calcium carbimide is less well characterized. Here, we describe four cases of liver damage related to this therapeutic group that were submitted to a Registry of hepatotoxicity and point out the limitations that we face when prescribing these compounds. A reassessment of the role of these compounds in the management of alcohol dependence is clearly needed.

This perspective shows an attempt to obtain synergy effects to fight ischemic stroke by combining agents acting on two different homeostatic mechanisms:inflammation and unfolded protein response (Anuncibay-Soto et al.,2018).Different pharmacological approaches have been assayed to alleviate cerebrovascular accident (stroke), which represents one of the most devastating diseases in the elderly.

Necroptosis has been reported in the last years as a type of regulated cell death that can be ignited by a number of specific death receptors,such as FAS,tumor necrosis factor receptor 1(TNFR1),or pathogen recognition *** cell death subroutine is involved in the response to stress and in homeostatic functions,such as the maintenance of adult T-cell balance(Galluzzi et al.,2018).Dead receptor activation leads to the recruitment of protein complexes that act as nodes of signaling that can elicit different pathways driving to death or survival,depending on the cell conditions.

AIM: To determine the hypothesis that inflating the balloons in the duodenal papilla determines changes in the biochemical markers of ***: Four groups of pigs were used: Group papilla(GP), the overtube's balloon was inflated in the area of the papilla; GP + double balloon enteroscopy(GP + DBE), the overtube's balloon was kept inflated in the area of the papilla for 20 min before a DBE; Group DBE(GDBE), DBE was carried out after insuring the balloon's inflation far from the pancreatic papilla; and Group control(GC). Serum concentrations of amylase, lipase and C-reactive protein(CRP) were evaluated. Pancreases were processed for histopathology ***: Main changes occurred 24 h after the procedure compared with baseline levels. Amylase levels increased significantly in GP(59.2% higher) and were moderately higher in groups GP + DBE and GDBE(22.7% and 20%, respectively). lipase increased in GP and GP + DBE, whereas it hardly changed in GDBE and in GC. CRP increased significantly in GP, GP + DBE and GDBE, while no changes were reported for GC. No statistically significant difference between groups GP and GP + DBE was found for the histopathological findings, except for vacuolization and necrosis of the pancreatic parenchyma that was higher in GP than in GP + ***: The manipulation of the duodenal papilla by the inflated overtube's balloon during DBE causes pancreatic structural damage and increased biochemical markers associated with pancreatitis.
