Second messenger cAMP and cGMP represent a key step in the action of dopamine that modulates directly or indirectly their synthesis. We aimed to verify whether levodopa-induced dyskinesias are associated with changes of the time course of levodopa/dopamine stimulated cAMP and cGMP levels, and/or with changes of their catabolism by phosphodiesterase activity(More)
BACKGROUND & AIMS Eradication of Helicobacter pylori using empiric therapy has become difficult as a result of increasing resistance to antibiotics. We evaluated the efficacy of specific treatments, selected based on response of bacterial samples to culture with clarithromycin, levofloxacin, and metronidazole, for patients infected with resistant strains of(More)
Italy's shift to a tertiary economy has modified the working market, concentrating demand also on unqualified one, which includes most immigrants. It is also well established that low socio-economical conditions are associated with an increased prevalence of H. pylori infection. The aims of this study were to compare: (1) the efficacy of a 7 days triple(More)
In the present study, we found that PDE10A inhibitor papaverine, alone or in combination with the D1 receptor agonist SKF38393, did not change spontaneous IPSCs (sIPSCs) frequency or amplitude in the substantia nigra pars reticulata (SNpr). An increase in frequency, but not in amplitude, of sIPSCs was only observed when SKF38393 and PDE10A inhibitors were(More)
Helicobacter pylori infection remains widespread internationally, with a definite morbidity and mortality. The efficacy of standard 7-14 day triple therapies is decreasing, mainly due to increasing primary bacterial resistance to antibiotics. Currently, the most effective treatments are either the sequential regimen or the concomitant therapy. Different(More)
BACKGROUND AND AIMS H. pylori eradication with standard therapies is decreasing worldwide, mainly because of increased primary antibiotic resistance rates. We aimed to assess primary resistance in H. pylori isolates towards the most used antibiotics in clinical practice. METHODS The study enrolled consecutive, dyspeptic, adult patients, never treated for(More)
Assessment of symptoms should be one of the main outcome measures in dyspepsia clinical trials. This requires a reliable, valid and responsive questionnaire that measures the frequency and severity of dyspeptic symptoms. The Short-Form Leeds Dyspepsia Questionnaire (SF-LDQ) has been proven to fulfil these criteria in its original version in the English(More)
Rapid diagnostic tools for Helicobacter pylori are important in endoscopy. To assess the accuracy of a new 5-min rapid urease test (UFT300, ABS Cernusco, sul Naviglio, Italy) compared with the 1-h Pyloritek (Serim Laboratories, Elkhart, IN) and the 24-h CLO test (Kimberly-Clark Ballard Medical Products, Roswell, GA), consecutive dyspeptic patients referred(More)
Primary clarithromycin resistance is the main factor affecting the efficacy of Helicobacter pylori therapy. This study aimed: (i) to assess the concordance between phenotypic (culture) and genotypic (real-time PCR) tests in resistant strains; (ii) to search, in the case of disagreement between the methods, for point mutations other than those reported as(More)
