Background: There is a need to improve the performance of urine cytology in bladder cancer diagnosis. We assessed the diagnostic performance of (i) telomerase activity detected by telomeric repeat amplification protocol (TRAP) assay, (ii) cytology and TRAP assay in parallel, (iii) cytology in parallel with the in-series combination of TRAP assay and FISH analysis, and (iv) the in-series combination of TRAP assay and FISH analysis. Patients and methods: Cross-sectional study of 289 consecutive patients who presented with urinary symptoms at a north Italian hospital between 2007 and 2008. All underwent cystoscopy and cytology evaluation, and conclusive results were available for TRAP assay and FISH analysis. Results: Sensitivity and specificity were 0.39 and 0.83, respectively, for cytology; 0.66 and 0.72 for TRAP; 0.78 and 0.60 for the combination of cytology and TRAP; 0.78 and 0.78 for the combination of cytology, TRAP, and FISH; and 0.65 and 0.93 for the combination of TRAP and FISH. All differences versus cytology alone were significant (P £ 0.011). Conclusion: Compared with cytology alone, the combination of cytology, TRAP, and FISH provided the best tradeoff between increase in sensitivity and loss in specificity, especially among non-bleeding patients, low-grade cancers, and early-stage cancers. © The Author 2011.

Background: Although non muscle invasive bladder cancer (NMIBC) generally has a good long-term prognosis, up to 80% of patients will nevertheless experience local recurrence after the primary tumor resection. The search for markers capable of accurately identifying patients at high risk of recurrence is ongoing. We retrospectively evaluated the methylation status of a panel of 24 tumor suppressor genes (TIMP3, APC, CDKN2A, MLH1, ATM, RARB, CDKN2B, HIC1, CHFR, BRCA1, CASP8, CDKN1B, PTEN, BRCA2, CD44, RASSF1, DAPK1, FHIT, VHL, ESR1, TP73, IGSF4, GSTP1 and CDH13) in primary lesions to obtain information about their role in predicting local recurrence in NMIBC. Methods. Formaldehyde-fixed paraffin-embedded (FFPE) samples from 74 patients operated on for bladder cancer were analyzed by methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA): 36 patients had relapsed and 38 were disease-free at the 5-year follow up. Methylation status was considered as a dichotomous variable and genes showing methylation ≥20% were defined as "positive". Results: Methylation frequencies were higher in non recurring than recurring tumors. A statistically significant difference was observed for HIC1 (P = 0.03), GSTP1 (P = 0.02) and RASSF1 (P = 0.03). The combination of the three genes showed 78% sensitivity and 66% specificity in identifying recurrent patients, with an overall accuracy of 72%. Conclusions: Our preliminary data suggest a potential role of HIC1, GSTP1 and RASSF1 in predicting local recurrence in NMIBC. Such information could help clinicians to identify patients at high risk of recurrence who require close monitoring during follow up. © 2013 Casadio et al.; licensee BioMed Central Ltd.

Background and aims: Severe hypoglycemia is not rare in diabetes and markedly impacts on health resource use. We aimed to describe the characteristics of patients attending emergency departments (EDs) following a severe episode of hypoglycemia, the factors associated with the management of events and the final outcome. Methods and results: We carried out a retrospective analysis of cases attending 46 Italian EDs for hypoglycemia from January 2011 to June 2012. A total of 3753 records were retrieved from the databases of the participating centers, part of a network repeatedly involved in collaborative studies; 3516 episodes occurred in subjects with diabetes (median age, 76 years; range, 1-102). Comorbidities were recorded in 2320 (65.9%) diabetes cases; association with trauma or road accidents in 287 (8.2%) and 47 (1.3%), respectively. Patients were treated with insulin (49.8%), oral agents (31.4%), or combination treatment (15.1%). The event required assistance by the out-of-hospital Emergency services in 1821 cases (51.8%). Following the ED visit, admission to hospital departments was deemed necessary in 1161 cases (33.1%). Diabetes treatment (oral agents: OR, 1.63; 95% confidence interval (CI), 1.37-1.94), increasing age (OR, 1.39; 95% CI, 1.31-1.48) and the number of comorbidities (OR, 1.51; 95% CI, 1.38-1.66) were the main drivers of admission. The in-hospital death rate was 10%, associated with the number of comorbidities (OR, 1.28; 95%CI, 1.01-1.63). Conclusion: Severe hypoglycemia requiring referral to EDs is associated with a significant work-up of the Emergency services and a remarkable in-hospital death rate in frail individuals with diabetes. © 2014 Elsevier B.V.

Oncological follow-up after radical gastrectomy for cancer still represents a discrepancy in the field, with many retrospective series demonstrating that early diagnosis of recurrence does not result in an improvement in patient survival; yet, many centers with high quality of care still provide routine patient follow-up after surgery by clinical and instrumental controls. This was the topic for a web round table entitled "Rationale and limits of oncological follow-up after gastrectomy for cancer" that was launched one year before the 10th International Gastric Cancer Congress. Authors having specific expertise were invited to comment on their previous publications to provide the subject for an open debate. During a three-month-long discussion, 32 authors from 12 countries participated, and 2299 people visited the dedicated web page. Substantial differences emerged between the participants: authors from Japan, South Korea, Italy, Brazil, Germany and France currently engage in instrumental follow-up, whereas authors from Eastern Europe, Peru and India do not, and British and American surgeons practice it in a rather limited manner or in the context of experimental studies. Although endoscopy is still considered useful by most authors, all the authors recognized that computed tomography scanning is the method of choice to detect recurrence; however, many limit follow-up to clinical and biochemical examinations, and acknowledge the lack of improved survival with early detection. © 2014 Baishideng Publishing Group Inc.

The purpose of this document is to develop recommendations on the use of the latest generation of cardiac troponins in emergency room settings for the diagnosis of myocardial infarction in patients with suspected acute coronary syndrome (ACS) without persistent ST- segment elevation (NSTE-ACS). The main points which have been addressed reaching a consensus are represented by: 1. Suitability and appropriateness of the terminology. 2. Appropriateness of the request. 3. Confirmation of the diagnosis of myocardial infarction (rule-in). 4. Exclusion of the diagnosis of myocardial infarction (rule-out). Work method: Each point has been analyzed by taking into account the evidence presented in medical publications. Recommendations were developed using the criteria adopted by the European Society of Cardiology and the American Heart Association/American College of Cardiology (www.escardio.org/guidelines). Each point of the recommendation was submitted for validation to an external audit by a Group of Experts (named above).
