The role of Pap test screening against cervical cancer: a systematic review and meta-analysis.

OBJECTIVE: The first aim of this article is to quantify the role of Pap test in cervical cancer prevention, updating the pool of available studies included in a previous meta-analysis. Potential sources of meta-analysis heterogeneity were investigated as second aim. Further evidence of cost-effectiveness has been provided about age and best time interval to perform Pap test screening. DATA SOURCES: The articles' search was conducted using four medical electronic databases: PubMed, Google Scholar, ISI Web, and Scopus. Papers published until the 30th November 2013 were included. The research on Google Scholar was limited to the first 10 pages of web for each study design. METOD OF STUDY SELECTION: A systematic review/meta-analysis was performed according to PRISMA Statement. New-Castle-Ottawa Scale and Jadad have been adopted for articles quality assessment. From 4143 screened articles, 34 met eligibility criteria and 30 case-control studies were included in meta-analysis. Meta-analysis was carried out using StatsDirect2.8.0. Heterogeneity was investigated with qualitative and quantitative approaches in sensitivity-analysis. TABULATION, INTEGRATION AND RESULTS: Despite a great heterogeneity (Cochran Q=504.466, df=29, p<0.0001; I²=94.3%; 95%CI=93.1%-95.1%), a significant protective effect of Pap test has been identified (OR=0.33; 95%CI=0.268-0.408, P <0.00011) through the meta-analysis. Sensitivity analysis did not provide significant results (R=0.358 R2=0.128 p<0.469). CONCLUSIONS: The protective role of Pap test against cervical cancer has been confirmed especially among women <40 years. Annual screening still remains the most cost-effective preventive strategy.

[The role of D-dimer in aortic dissection]. / Il D-dimero nella dissezione aortica.

OBJECTIVES: The aim of this retrospective study is to indicate the correlation between the grade of the extent of the aortic pathology, the presence of complications, the evolution of the pathology value of the D-dimer in all the patients with aortic dissection in order to know a prognostic role a short-long time of this test. MATERIALS AND METHODS: Only in 40 patients were possible to determine the value of D-dimer priol of these patients were not received invasive cares. The patients are divided into 4 classes in accordance with the extent of the aortic pathology valued TAC images and after we have taken in observation the presence of clinical complications shown and the positive history for chronic aortic dissection. RESULTS: The elevation of D-dimer is strictly associated with the extent of the aortic dissection. The value of D-dimer is more elevated during the progress of the pathology and in the presence of clinical complications than during chronic aortic dissection. CONCLUSIONS: The D-dimer is considered a diagnostic marker by the clinicians during the acute setting of the aortic dissection. A lot of points of view should be valued and cleared, its possible to attribute a prognostic role at the D-dimer during the acute aortic dissection.
