Eur J Clin Invest 2012; 42 (10): 1068-1078 ABSTRACT: Background In many countries, the introduction of generic proton pump inhibitors (PPIs) onto the pharmaceutical market increased the phenomenon of therapeutic substitution in acid-related disorders (ARDs). Aim To investigate the treatment of ARDs in an Italian primary care setting from 2005 to 2008 by verifying: (i) dynamics of PPI prescribing; (ii) predictors of PPI switching; and (iii) healthcare resource consumption costs. Methods This was a retrospective cohort study of 102 general practitioners (GPs) who managed an average of 150?000 inhabitants in Naples. Multilevel logistic regression was used to assess the potential predictors of both PPI switching and termination. Primary care costs were expressed as the cost of ARD management per PPI user year. Results The percentage of PPI users with ARD increased from 5·5% (2005) to 7·0% (2008) (P?0·0001), especially for dyspepsia (from 9·5% to 13·7%; P?0·0001) and chronic treatments (from 23·4% to 29·4%; P?0·0001). PPI switching rose from 13·0% to 16·7% during the period observed (P?0·0001). Calendar years, long-term treatments and gastroesophageal reflux disease were positive predictors of PPI switching. Primary care costs relating to PPI switchers increased by 61·14€ compared with nonswitchers (P?0·0001). Conclusions The introduction of generic PPIs onto the Italian market was associated with an increasing amount of PPI prescribing related to chronic treatments, unlicensed indications (e.g. dyspespsia) and therapeutic substitutions. Growing overall costs linked to the phenomenon of PPI switching was also found. Our data support the need to assess the effects of the introduction of generic drugs on both clinical outcomes and the cost management of ARDs. 相似文献

Background
Intestinal inflammation is partly driven by enteroglial-derived S100B protein. The antiprotozoal drug pentamidine directly blocks S100B activity. We aimed to investigate the effect of pentamidine on intestinal inflammation using an animal model of dextran sodium sulphate (DSS)-induced acute colitis.Methods
Mice were divided into: control group, colitis group (4% DSS for four days) and two pentamidine-treated colitis groups (0.8?mg/kg and 4?mg/kg). Anti-inflammatory effect of pentamidine was assessed in colonic tissue by evaluating the disease activity index and the severity of histological changes. Colonic tissue were also used to evaluate cyclooxigenase-2, inducible nitric oxide synthase, S100B, glial fibrillary acidic protein, phosphorylated-p38 MAPkinase, p50, p65 protein expression, malondyaldheyde production, mieloperoxidase activity, and macrophage infiltration. Nitric oxide, prostaglandin E2, interleukin-1 beta, tumor necrosis factor alpha, and S100B levels were detected in plasma samples. Parallel measurements were performed in vitro on dissected mucosa and longitudinal muscle myenteric plexus (LMMP) preparations after challenge with LPS?+?DSS or exogenous S100B protein in the presence or absence of pentamidine.Results
Pentamidine treatment significantly ameliorated the severity of acute colitis in mice, as showed by macroscopic evaluation and histological/biochemical assays in colonic tissues and in plasma. Pentamidine effect on inflammatory mediators was almost completely abrogated in dissected mucosa but not in LMMP.Conclusions
Pentamidine exerts a marked anti-inflammatory effect in a mice model of acute colitis, likely targeting S100B activity. Pentamidine might be an innovative molecule to broaden pharmacological tools against colitis.83.
Breakthrough Pain in Patients Referred to Pain Clinics: The Italian Pain Network Retrospective Study

Introduction
Despite breakthrough pain (BTP) being one of the most severe forms of pain, there are no definitive data on its prevalence.Methods
The authors performed a retrospective survey of the prevalence of BTP in consecutive patients in four Italian pain clinics, subsequent to application of an Italian law mandating detailed clinical records on pain characteristics, treatment, and results. Mean pain intensity was assessed with a numerical rating scale from 0 to 10.Results
The authors analyzed records of 1,401 patients (58% women, 33.1% patients with cancer). Transient episodes of severe pain or BTP were referred by 790 patients (56.4%), including 58.2% of the men (342 of 588) and 55.1% of the women (448 of 813). Among the 464 patients with cancer, 70.3% reported daily exacerbation of pain. The mean BTP intensity was 8.31 ± 1.58 and 31.1% of patients reported experiencing three episodes per day.Conclusion
Despite some limitations of the study, the authors show that transient episodes of severe pain or BTP are significantly present both in cancer and other diseases, and that many patients are not yet receiving appropriate opioid therapy. The authors need validated tools at international level for the diagnosis and treatment of BTP in patients with cancer and for transitory and patients with severe non-cancer pain. A survey at national level is needed to estimate the prevalence of BTP in different settings, to plan specific medical education. 相似文献84.

With anesthesia awareness as a model of study we debate the both fascinating and dangerous phenomenon called consciousness fluctuation that takes place during surgical anesthesia. In accordance with current scientific knowledge this paradox is the consequence of our limits in both precise knowledge of anesthesia mechanisms and our inability to accurately assess the level of anesthesia with brain monitoring. We also focus on the relationships between memory and anesthesia, as well as the possibility of interfering with memory during general anesthesia. 相似文献

To determine whether abnormal left ventricular diastolic function is present at an early stage of non-insulin-dependent diabetes mellitus (NIDDM), left ventricular diastolic filling was evaluated by pulsed doppler echocardiography in 16 normotensive patients with NIDDM of short duration (1.8 ± 1 years, mean ± SD) and no evidence of microangiopathy, and in 16 healthy volunteers comparable for age, body mass index, and sex distribution. All patients showed normal systolic function. The interventricular septum thickness, left atrial diameter, and left ventricular mass index were increased in the diabetic as compared with the control group (p < 0.01, p < 0.01, and p < 0.02, respectively). Isovolumic relaxation time and atrial peak filling velocity were greater in diabetic patients (p < 0.001, and p < 0.01, respectively), whereas early to atrial peak filling velocity ratio was significantly reduced (p < 0.05). This study demonstrates that an impairment of left ventricular diastolic function occurs early in the natural history of NIDDM, and that this abnormality is unlikely to be related to clinical evidence of microangiopathic complications. 相似文献
