Histamine and Delirium: Current Opinion

This study indicated that switch from H2 blockers to PPIs reduced delirium and, thus, providing an appropriate strategy to combat drug-induced delirium using antiulcer drugs (Fujii et al., 2012). The ventrolateral preoptic nucleus is a sleep-promoting nucleus located in the basal forebrain. A commonly used intravenous anesthetic, propofol, had been reported to induce sleep and augment the firing rate of neurons in ventrolateral GABAergic preoptic nucleus, but the underlining mechanism is yet to be clearly determined. Interestingly, the propofol-induced inhibition of inhibitory postsynaptic currents on noradrenalin-inhibited neurons have been shown to be mediated by histaminergic H1 and H2 receptors (Liu et al., 2017). Opioids and Histamine Interactions An interaction between histaminergic and opioidergic systems within the CNS was proposed three decades ago, suggesting that analgesia produced by opioids may be associated with release of histamine and the stimulation of histamine receptors at the supraspinal (central) level (Nishibori et al., 1985). Many more recent studies have shown that histamine receptor antagonists can modulate the analgesic action of opioids, however, the site and mode of action of this interaction differs between the spinal or supraspinal level, and depends on the subtype of histamine receptor (Mobarakeh et al., 2002, 2006, 2009; Stein et al., 2016). A series of studies have also shown than in H1R and H2R KO mice, morphine-induced antinociception was ...

We describe a contiguous gene deletion of the ATM locus in a multi-generation family of Italian descent with a strong family history of pancreatic cancer. A deletion of one copy of the entire ATM gene was identified by routine panel testing and further characterized by chromosomal microarray analysis. An 11q22.3 microdeletion of approximately 960kb was identified that is predicted to result in loss of 10 genes including ATM. The deletion was identified in two additional family members including a presymptomatic daughter and an affected sibling. A normal disomic complement of the 11q22.3 region was detected in a third famil...

ConclusionsBronchodilator dose responsiveness may be useful for phenotyping and may be of utility in practice and future studies focused on asthma outcomes or quantification of treatment responses. In children and adolescents, this phenotype of poor bronchodilator responsiveness may be associated with periods of relatively stable disease yet marked airway constriction in response to triggers, including tobacco smoke, respiratory infections/pneumonia, and aeroallergens.
