The calcium-sensing receptor (CaSR) has been detected in human antral gastrin-secreting cells, where, upon calcium and/or amino acid allosteric activation, it stimulates gastrin secretion. Patients with absorptive hypercalciuria (AH) display an enhanced gastric acid output; therefore, we evaluated the secretion of gastrin in subjects with AH (30 subjects(More)
We here present an unusual case of hypokaliemic rhabdomyolysis, characterised by a sthenic deficit exclusively involving the distal muscles of the upper limbs and secondary to chronic glycyrrhizic acid intoxication, and by the absence of even ictal arterial hypertension. We discuss the etiopathogenetic bases and the risks related to the development of this(More)
In their work Gilio et al. (2008) investigate the mechanisms involved in the regulation of excitability of the cortex in epileptic subjects, and in particular their epileptogenic threshold. Authors propose an experimental strategy established on the following assumptions: 1) Most of the authors consider that epileptogenic foci are expression of cortex(More)
Absorptive hypercalciuria (AH) is associated with elevated levels of 1,25-dihydroxyvitamin D (1,25(OH)(2)D). While no increase of 1,25(OH)(2)D after oral administration of 25-hydroxyvitamin D (25OHD) at high doses has been claimed in normal subjects, a substrate-product relationship has been reported in normal children, young people after UV irradiation,(More)
