Cerano is a municipality of the Province of Novara (North-West Italy). To assess the morbidity associated to its proximity to a petrochemical plant, standardized incidence ratios (SIRs) of oncological pathologies in the period 2003–2009 were calculated based on age-sex specific rates for the district of the Local Health Authority of Novara (ASL13) and the main regional city of Turin. For all cancers combined, men showed a significant higher risk (SIR: 1.21; 95% CI: 1.02–1.40) compared to the ASL13 population; significantly lower risks for both men and women were observed in comparison to the Turin population. Among women, a significant excess of mesothelioma cancers was reported; a significantly higher risk for lympho-haematopoietic pathologies was also observed compared to the Turin population only. Several other cancers have significantly lower rates in Cerano for both men and women. Despite some studies’ limitations, these findings could suggest potential chemical risk factors and need further investigation. 相似文献

The autosomal recessive disease cystic fibrosis (CF) was once untreatable and deadly in childhood, but now most patients survive to adulthood. Many countries have instituted CF newborn screening because early diagnosis improves outcome. CF research has greatly intensified following the discovery of the CF transmembrane conductance regulator (CFTR) gene, which has more than 2000 different mutations. For patients with common mutations like F508del, CFTR modulators are life transforming and may even prevent major complications if started early in childhood. For some patients with rare CFTR mutations, a treatment path still needs to be developed. Conclusion: This review provides a general update on CF, including screening and current and future treatment. 相似文献

Alcohol is a known hepatotoxic agent, which may exacerbate liver injury caused by other agents. The wide prevalence of alcohol use and abuse in society makes it an important cofactor in many other liver diseases. Examples of liver diseases that are significantly influenced by ingestion of alcohol include chronic viral hepatitis, disorders of iron overload, and obesity-related liver disease. 相似文献

Prognostic factors in acute pancreatitis. 总被引:25,自引:0,他引:25
The assessment of the severity of acute pancreatitis (AP) is a critical early step in its management, as severity of AP predicts prognosis. A range of options are available for assessment of severity in AP, including clinical evaluation, standardized prognostic criteria, computed tomography (CT), and biochemical markers. Clinical assessment has limited accuracy for predicting severity early in the course of AP. Therefore, additional assessment using biochemical and radiologic criteria in combination with standardized criteria is appropriate to determine severity and prognosis in AP; a strategy emphasizing daily assessment of severity should be used. The APACHE II is the scoring system of choice for evaluating severity in AP, although it remains an imperfect tool. Computed tomographic grading of AP and the development of the CT severity index allow for heightened accuracy in the prediction of severity. C-Reactive protein is the standard for serum marker assessment of severity and prognosis in AP; other markers, including interleukin-6, polymorphonuclear elastase, and trypsinogen activation peptide, hold promise. The focus of this review is to examine the role of diagnostic tests in evaluating severity and predicting prognosis among patients with AP and to provide a diagnostic algorithm for initial management. 相似文献
