Abstract
This paper reports the results of the active pharmaceutical ingredient (API) fingerprint study, organised by the General European Official Medicines Control Laboratory Network (GEON), on tadalafil. A classical market surveillance study, evaluating compliance to the European Pharmacopoeia, was combined with a fingerprint study, the latter to obtain characteristic data for the different manufacturers, allowing the network laboratories to conduct authenticity tests for future samples, as well as to detect substandard and falsified samples. In total, 46 tadalafil API samples from 13 different manufacturers were collected. For all samples fingerprint data was collected through analysis of impurities and residual solvents, mass spectrometric screening, X-ray powder diffraction and proton nuclear magnetic resonance (1H-NMR). Chemometric analysis revealed that all manufacturers could be characterised based on the impurity, residual solvent and 1H-NMR data. Future suspicious samples in the network will therefore be analysed with these techniques in order to attribute the sample to one of the manufacturers. If the sample cannot be attributed, a more profound investigation will be necessary to reveal the origin of the sample. In cases where the suspect sample is claimed to be from one of the manufacturers included in this study, analysis can be limited to the test distinguishing that manufacturer.

Abstract
Rheumatic musculoskeletal diseases or RMD [rheumatoid arthritis (RA) and spondyloarthritis (SpA)] are systemic inflammatory diseases for which there are no biomarkers capable of predicting treatments with a higher likelihood of response in naive patients. In addition, the expiration of the anti-TNF blocking drugs' patents has resulted in the availability of anti-TNF biosimilar drugs with the same efficacy and safety than originators but at significantly reduced prices. To guarantee a personalized therapeutic approach to RMD treatment, a board of rheumatologists and stakeholders from the Campania region, Italy, developed a clinically applicable arthritis therapeutic algorithm to guide rheumatologists (DATA project). The general methodology relied on a Delphi technique forecast to produce a set of statements that summarized the experts' consensus. Selected clinical scenarios were discussed in light of the available evidence, and there were two rounds of voting on the therapeutic approaches. Separate discussions were held regarding rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis. The decision-making factors for each disease were clinical presentation, demographics, and comorbidities. In this paper, we describe a virtuous process between rheumatologists and healthcare system stakeholders that resulted in the development of a shared therapeutic algorithm for RMD patients naive to bDMARDs.

Abstract
Through its Active Pharmaceutical Ingredient Working Group (API-WG) the General European Official Medicines Control Laboratory (OMCL) Network (GEON), co-ordinated by the European Directorate for the Quality of Medicines & HealthCare (EDQM), regularly organises market surveillance studies for specific APIs for conformity to their monograph in the European Pharmacopoeia. During the past years some studies were combined with a fingerprint study of the APIs. The idea is to obtain a fingerprint for each manufacturer of the API under investigation, allowing the OMCL network to identify future samples as well as to detect substandard and falsified APIs. This paper reports the results of the latest fingerprint study, organised on sildenafil citrate API samples. Seventy-nine samples from 14 different manufacturers were collected throughout the Network. Fingerprint data was collected through Mid-Infrared spectroscopy, Raman spectroscopy, liquid chromatography for related substances, gas chromatography for residual solvents, X-ray diffraction and Nuclear Magnetic Resonance (NMR) spectroscopy. Chemometrics applied to the collected data showed that all manufacturers could be discriminated based on the data of only three of these tests, i.e. gas chromatography for residual solvents, X-ray diffraction and proton NMR. Suspicious API samples for sildenafil citrate will therefore be analysed in the future with the selected techniques in order to link the sample to a manufacturer or demonstrate the absence of such link. If the sample cannot be attributed to one of the manufacturers, further analysis and research on provenance and identity will be required. Of course, if the suspected sample claims to originate from one of the manufacturers included in the study, analysis can be limited to the test distinguishing this manufacturer.

Abstract
BACKGROUND AND OBJECTIVES Despite the procedures adopted for the selection of blood donors, in Italy the HIV prevalence per 100 000 repeat tested donors (RTD) and first-time tested donors (FTD) is high compared to most other Council of Europe member states. To evaluate the effectiveness of predonation procedures, we studied both the characteristics and the undisclosed risk behaviours of HIV-positive donors. MATERIALS AND METHODS We analysed the data from the Italian blood donor surveillance system in 2009, 2010 and 2011. Based on the postdonation interview, HIV-positive donors were classified by risk behaviour (heterosexual, MSM, 'non-sexual' and 'not determined') and by time elapsed from risk behaviour to donation. In Italy, the temporary deferral for exposure to behaviour at risk is 4 months. RESULTS In the postdonation interview, 113 HIV-positive donors (32·4%), who denied at-risk behaviours in the predonation selection, reported sexual risk behaviours <4 months prior to donation; they were predominantly males (84·1%) and RTD (63·7%). The main reason for not having reported the risk behaviour in the predonation selection was 'not realizing having engaged in at-risk behaviour' (66·4%). CONCLUSION These findings underline the need for more comprehensible educational material, a clearer predonation questionnaire, and effective information campaigns to improve the awareness of HIV sexual risk behaviours among blood donors.

Abstract
Aberrant expression of a zinc transporter ZIP4 in pancreatic ductal adenocarcinoma (PDAC) has been shown to contribute to tumor progression and is a potential target for individualized therapy. The overall objective of this study was to determine whether ZIP4 could serve as a novel diagnostic and prognostic marker in human PDAC, and if it can be assessed by minimally invasive sampling using endoscopic ultrasound guided fine needle aspiration (EUS-FNA). Immunohistochemistry was performed to compare ZIP4 expression in the PDAC samples obtained from EUS-FNA and matched surgical tumors (parallel control). Samples were reported by sensitivity, specificity, and predictive values, all with 95% confidence intervals (CI). A total of 23 cases with both FNA and surgical specimens were evaluated. We found that ZIP4 was significantly overexpressed in tumor cells from both sets of samples. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ZIP4 for the diagnosis of PDAC were 72.9%, 72.5%, 76.1%, and 69.0% in EUS-FNA samples, and were 97.9%, 65.4%, 83.9%, and 94.4% in surgical specimens, respectively. The association between the positive rate of ZIP4 expression in FNA and surgical samples is statistically significant (P=0.0216). Both the intensity and percentage of ZIP4 positive cells from the surgical samples correlated significantly with tumor stage (P=0.0025 and P=0.0002). ZIP4 intensity level in FNA samples was significantly associated with tumor differentiation and patient survival. These results indicate that EUS-FNA is capable of non-operative detection of ZIP4, thus offering the potential to direct pre-operative detection and targeted therapy of PDAC.

Abstract
BACKGROUND Numerous laboratories in Italy use radioimmunoassay to determine concentrations of sex hormones (FSH, LH, testosterone). A comparison of assay methods is thus an important starting point for the achievement of universally accepted reference values. AIM To carry out an external quality assessment for FSH, LH, and testosterone. MATERIALS AND METHODS Fifteen aliquots from 5 serum pools were assayed in multiple replicates by 16 Italian laboratories with 5 automated immunoassays (Abbott Architect, DiaSorin Liaison, Perkin-Elmer AutoDelfia, Roche Elecsys, Siemens Immulite 2000), and 1 radioimmunoassay (Adaltis). RESULTS The variance was below 12% for FSH, between 11.61% and 14.76% for LH, and between 9.57% and 12.48% for testosterone. Assay precision was good, except for Elecsys at low concentrations of FSH and for Immulite at low concentrations of LH and testosterone. ARCHITECT showed a negative bias for FSH and LH and a positive bias for testosterone; Liaison a positive bias for LH; Elecsys a positive bias for FSH and a negative bias for testosterone; Immulite a positive bias for FSH; AutoDelfia a negative bias for FSH and a positive bias for testosterone. Reference ranges at the low end varied widely, even among laboratories using the same assay. CONCLUSIONS The analytical performances of widely used immunoassays for FSH, LH, and testosterone show a fair to strong degree of consistency. A careful evaluation of reference ranges by clinical and laboratory experts needs to be carried out, in order to reach a consensus.

Abstract
BACKGROUND AND STUDY AIMS There have been concerns regarding tumor cell seeding along the needle track or within the peritoneum caused by preoperative endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). The aim of this study was to evaluate whether preoperative EUS-FNA is associated with increased risk of stomach/peritoneal recurrence and whether the procedure affects long term survival. METHODS The records of patients diagnosed with malignant solid and cystic pancreatic neoplasms who underwent surgery with curative intent between 1996 and 2012 were reviewed. RESULTS A total of 256 patients with similar baseline characteristics were included: 48 patients in the non-EUS-FNA group and 208 in the EUS-FNA group. Recurrence data were available for 207 patients. Median length of follow-up was 23 months (range 0 - 111 months). A total of 19 patients had gastric or peritoneal recurrence; 6 (15.4 %) in the non-EUS-FNA group vs. 13 (7.7 %) in the EUS-FNA group (P = 0.21). Three patients had recurrence in the stomach wall: one (2.6 %) patient in the non-EUS-FNA group vs. two patients (1.2 %) in EUS-FNA group (P = 0.46). A total of 16 patients had peritoneal recurrence: 5 patients (12.8 %) in the non-EUS-FNA group and 11 patients (6.5 %) in the EUS-FNA group (P = 0.19). In a multivariate analysis, undergoing EUS-FNA was not associated with increased cancer recurrence or decreased overall survival. CONCLUSION Pre-operative EUS-FNA was not associated with an increased rate of gastric or peritoneal cancer recurrence in patients with resected pancreatic cancer. Two patients had gastric wall recurrence following the procedure, but this may be explained by direct tumor extension. This suggests that EUS-FNA is not associated with an increased risk of needle track seeding.

Abstract
BACKGROUND AND STUDY AIMS Probe-based confocal laser endomicroscopy (pCLE) is a new imaging modality that enables histological examination of gastrointestinal mucosa during endoscopic procedures. Most studies have evaluated offline interpretation of pCLE images. In clinical practice, real-time interpretation is necessary to assist decision-making during the procedure. The aim of this pilot study was to compare the accuracy of real-time pCLE diagnosis made during the procedure with that of blinded offline interpretation to provide accuracy estimates that will aid the planning of future studies. PATIENTS AND METHODS pCLE was performed in patients undergoing screening and surveillance colonoscopy. Once a polyp had been identified, one endoscopist analyzed pCLE images during the procedure and made a provisional "real-time" diagnosis. Saved video recordings were de-identified, randomized, and reviewed "offline" 1 month later by the same endoscopist, who was blinded to the original diagnoses. RESULTS Images from a total of 154 polyps were recorded (80 neoplastic, 74 non-neoplastic). The overall accuracy of real-time pCLE diagnosis (accuracy 79%, sensitivity 81%, specificity 76%) and offline pCLE diagnosis (83%, 88%, and 77%, respectively) for all 154 polyps were similar. Among polyps < 10 mm in size, the accuracy of real-time interpretation was significantly lower (accuracy 78%, sensitivity 71%, specificity 83%) than that of offline pCLE interpretation (81%, 86%, 78%, respectively). For polyps ≥ 10 mm, the accuracy of pCLE diagnosis in real-time was better (accuracy 85%, sensitivity 90%, specificity 75%) than offline pCLE diagnosis (81%, 97%, and 50%, respectively). CONCLUSIONS These results suggest that real-time and offline interpretations of pCLE images are moderately accurate. Real-time interpretation is slightly less accurate than offline diagnosis, but overall both are comparable. Additionally, there was contrasting accuracy between the two methods for small and large polyps.

Abstract
BACKGROUND AND STUDY AIMS Colonoscopy is widely used to detect and remove precancerous polyps, but fails to detect some polyps. Recent studies evaluating different image-enhanced methods have revealed conflicting results. The efficacy of colonoscopy imaging with simultaneous use of commercially available improvements, including high definition narrow band imaging (HD-NBI), and monochromatic charge-coupled device (CCD) video, was compared with a widely used standard definition white light (SDWL) colonoscopy system for detecting colorectal polyps. The primary aim was to determine whether the combination of image-enhanced colonoscopy systems resulted in fewer missed polyps compared with conventional colonoscopy. PATIENTS AND METHODS In a randomized controlled trial (Clinicaltrials.gov. study number NCT00825292) patients having routine screening and surveillance underwent tandem colonoscopies with SDWL and image-enhanced (HD-NBI) colonoscopy. The main outcome measurement was the per-polyp false-negative ("miss") rate. Secondary outcomes were adenoma miss rate, and per-patient polyp and adenoma miss rates. RESULTS 100 patients were randomized and 96 were included in the analysis. In total, 177 polyps were detected; of these, 72 (41 %) were adenomatous. Polyp and adenoma miss rates for SDWL colonoscopy were 57 % (60/105) and 49 % (19/39); those for image-enhanced colonoscopy were 31 % (22/72) and 27 % (9/33) (P = 0.005 and P = 0.036 for polyps and adenomas, respectively). Image-enhanced and SDWL approaches had similar per-patient miss rates for polyps (6/35 vs. 9/32, P = 0.27) and adenomas (4/22 vs. 8/20, P = 0.11). CONCLUSIONS Utilization of multiple recent improvements in image-enhanced colonoscopy was associated with a reduced miss rate for all polyps and for adenomatous polyps. It is not known which individual feature or combination of image-enhancement features led to the improvement.

Abstract
The feasibility of recycling spent foundry sand in clay bricks was assessed in laboratory, pilot line and industrial trials, using naturally occurring sand as a reference. Raw materials were analyzed by X-ray fluorescence, X-ray diffraction, particle size distribution, and leaching and combined to produce bodies containing up to 35% wt. sand. The extrusion, drying and firing behaviour (plasticity, drying sensitivity, mechanical strength, bulk density, water absorption, and shrinkage) were determined. The microstructure, phase composition, durability and leaching (EN 12457, granular materials, end-life step, European Waste Landfill Directive; NEN 7345, monolithic materials, use-life step, Dutch Building Material Decree) were evaluated for bricks manufactured at optimal firing temperature. These results demonstrate that spent foundry sand can be recycled in clay bricks. There are no relevant technological drawbacks, but the feasibility strongly depends on the properties of the raw materials. Spent foundry sand may be introduced into bricks up to 30% wt. Most of the hazardous elements from the spent foundry sand are inertized during firing and the concentrations of hazardous components in the leachates are below the standard threshold for inert waste category landfill excepting for chromium and lead; however, their environmental risk during their use-life step can be considered negligible.

Abstract
Neuroendocrine tumors are a heterogeneous group of rare tumors originating from neuroendocrine cells with secretory characteristics, and are primarily located in gastric, duodenal, pancreatic, and small and large bowel mucosa. Due to their extremely variable biologic and clinical behaviour, diagnosis is often delayed after a prolonged workup. Many advances have been made in recent years in the diagnosis, characterization, and treatment of neuroendocrine tumors. This review focuses on pancreatic neuroendocrine tumors, discussing the relatively new, multidisciplinary approach to their management. A Pubmed search was performed, limited to papers published within the last five years, using the key words NETs, pancreatic NETs, pancreatic tumors, diagnosis, imaging, nuclear imaging, endoscopy, endoscopic ultrasound, and biochemical markers.

Abstract
BACKGROUND AND STUDY AIMS Cystic pancreatic lesions (CPLs) are increasingly detected by various imaging studies. Mucinous CPLs carry a risk of malignant transformation but this is often difficult to diagnose preoperatively. In a previous report of 10 suspected mucinous CPLs, the cellular yield of endoscopic ultrasonography (EUS)-guided cytology brushings was found to be superior to the yield from standard fine-needle aspiration (FNA). The aim of this prospective and blinded study was to compare the cytology yield of mucinous epithelium from brushing with FNA in suspected mucinous CPLs. PATIENTS AND METHODS In total, 37 patients with 39 CPLs measuring at least 20 mm were enrolled between June 2006 and July 2008 for EUS-cytobrushing and EUS-FNA of CPLs. Demographic, clinical, EUS, cytopathologic, and surgical data were recorded whenever available. Yield of cytology brushings was compared with that of FNA. Procedure morbidity was evaluated after 30 days. The main outcome assessed was yield of intracellular mucin (ICM) on cytobrushing specimens compared with EUS-FNA for the diagnosis of suspected mucinous CPL. RESULTS Cytobrushings were more likely to detect ICM than the EUS-FNA method ( P = 0.001). In three patients with hypocellular FNA, dysplasia was found on cytology brushing and later confirmed by surgical pathology. Significant complications occurred in three patients (8 %): one postbrushing bleeding and two acute pancreatitis. CONCLUSIONS Cytology brushings are more likely to provide an adequate mucinous epithelium specimen than standard FNA and could aid the diagnosis of CPLs in a selective group of patients.

Abstract
Disposal of PC monitors and TV sets is a growing problem, with over 40% of the weight of these systems comprised of waste glasses with high Pb (funnel) or Ba-Sr concentrations (panel), making them unsuitable for recycling and manufacturing new glass. A possible way to re-use these glasses is in the manufacturing of clay bricks and roof tiles. This possibility was appraised by laboratory simulation of the brickmaking process and technological characterization of unfired and fired products. The recycling of both funnel and panel glasses into clay bodies is technologically feasible, resulting in a substantially reduced plasticity behaviour during shaping-drying (implying a reduction of mechanical strength), and a promotion of sintering during firing. No significant release of Pb, Ba, and Sr was observed during the firing and leaching test for the carbonate-poor body; in contrast, some Pb volatilization during firing and Sr leaching were observed for the carbonate-rich body. Additions of 2 wt.% appear to be practicable, while 5 wt.% glass induces unacceptable modifications of technological properties. The recommended amount is within 2 and 4 wt.%, depending on the characteristics of the clay bodies. The main constraint is that the glass must have a particle size below the limit of the pan mills used in brickmaking (<1mm).

Abstract
OBJECTIVE To evaluate efficacy of methotrexate treatment in peripheral arthritis of ulcerative colitis. METHODS We studied 18 patients (10/8 M/F; mean age: 38.90 yrs; range: 21-65 yrs), with peripheral arthritis (14 with polyarticular, 4 with oligoarticular subset) associate ulcerative colitis. Methotrexate 20 mg/week was administered in our patients, who were already receiving mesalazina for inflammatory bowel disease. At baseline, after 3 (T1), 6 (T2) and 12 months (T3) serological parameters (ESR and CRP), functional status (HAQ) and disease activity (VAS, GH, Ritchie articular index) were evaluated. RESULTS During the therapy a significant improvement was observed in disease activity, functional status and serological parameters since T1. ESR and CRP did not change at T2 and T3. Instead VAS, GH, Ritchie articular index and HAQ had a significant and gradual improvement from T1 to T3. CONCLUSION Methotrexate treatment was efficacious in the treatment of peripheral arthritis associate ulcerative colitis. This drug induced improvement in disease activity, functional status and serological parameters after 3 months of therapy.

Abstract
Barrett's esophagus (BE) with high-grade dysplasia (HGD) or early carcinoma treated with surgery or photodynamic therapy (PDT) is at risk of recurrence. The efficacy of endoscopic ultrasound (EUS) for surveillance after PDT is unknown. Our objective was to determine if EUS is superior to esophagogastroduodenoscopy (EGD) and/or CT scan for surveillance of BE neoplasia after PDT. The study was designed as a retrospective review with the setting as a tertiary referral center. Consecutive patients with BE with HGD or carcinoma in situ treated with PDT were followed with EUS, CT scan and EGD with jumbo biopsies every 1 cm at 3, 4, or 6-month intervals. Exclusion criteria was < 6 months of follow up and/or < 2 EUS procedures. Main outcome measurements were residual or recurrent disease discovered by any method. Results showed that 67/97 patients met the inclusion criteria (56 men and 11 women). Median follow-up was 16 months. Recurrent or residual adenocarcinoma (ACA) was detected in four patients during follow-up. EGD with random biopsies or targeted nodule biopsies detected three patients. EUS with endoscopic mucosal resection of the nodule confirmed T1 recurrence in one of these three. In the fourth patient, CT scan revealed perigastric lymphadenopathy and EUS-FNA (fine needle aspiration) confirmed adenocarcinoma. There were two deaths, one related to disease progression and one unrelated. The rate of recurrent/persistent ACA after PDT was 4/67 = 6%. EUS did not detect disease when EGD and CT were normal. Limitations of this study include non-blinding of results and preferential status of non-invasive imaging (CT) over EUS. Our experience suggests that EUS has little role in the surveillance of these patients, unless discrete abnormalities are found on EGD or cross-sectional imaging.

Abstract
BACKGROUND AND STUDY AIMS Fine-needle aspiration (FNA) is commonly performed in conjunction with endoscopic ultrasound (EUS) procedures. The complication rate associated with FNA is considered to be low but requires further evaluation with prospective studies. PATIENTS AND METHODS A total of 483 consecutive patients who underwent EUS-guided FNA over a 12-month period were prospectively enrolled in the study. The patients were screened for postprocedural complications, including abdominal pain, nausea, vomiting, and gastrointestinal bleeding. Complications were assessed immediately after EUS-FNA and 30 days later with a telephone call, when inquiries were made about emergency room and physician's office visits or hospitalizations during this 30-day period. RESULTS Complete information was obtained from 414 patients (86 %). Complications occurred in seven patients during the first day. Five of these patients had unplanned admissions to hospital: two patients were observed because they had abdominal pain after FNA of pancreatic cysts; one patient was observed because they developed chest pain after mediastinal lymph node FNA; and two patients were monitored after celiac node FNA, one with a transient fever and one with self-limited melena. All five of these patients were discharged within 24 hours of admission, none required blood transfusion, and none showed any evidence of pancreatitis or infection. Two other patients visited the emergency department but were discharged on oral analgesics after appropriate evaluation. By day 30 six patients had died as a result of their primary disease process. There was no unexpected morbidity or mortality attributable to the EUS-FNA. CONCLUSIONS FNA is a safe intervention in patients undergoing EUS in a high-volume academic center, with a low postprocedural complication rate.

Abstract
BACKGROUND AND STUDY AIMS Advances in endoscope design have allowed high-quality imaging using small-caliber endoscopes (< 6 mm), and these have been proposed as providing an accurate modality for evaluating esophageal varices in several small studies. We aimed to evaluate the accuracy and interobserver agreement of small-caliber esophagogastroduodenoscopy (EGD) compared with conventional EGD for evaluating esophageal varices in a large prospective cohort. PATIENTS AND METHODS A total of 115 patients with end-stage liver disease and/or portal hypertension were prospectively enrolled into the study. EGD procedures were performed using conventional (8.6-mm) and small-caliber (4.9-mm) endoscopes, back to back and under standard sedation, by two different endoscopists. Esophageal varices were graded at the time of EGD (the "real-time" grade); and by retrospective review of photographs by three endoscopists, when a "consensus" grade (i. e. a grading agreed by two out of the three endoscopists) was used as the final result. RESULTS Of the 115 patients, 33 patients (29 %) were classified as Child's class A, 47 patients (41 %) as Child's class B, and 35 patients (30 %) as Child's class C. The mean model for end-stage liver disease (MELD) score was 13.6. Thirty-six patients (31 %) had undergone previous ligation of esophageal varices. Compared with conventional EGD, the accuracy of small-caliber EGD for esophageal varices grading was 94 % (consensus grade) and 95 % (real-time grade). Excellent concordance was demonstrated between real-time grade and consensus grade, with a kappa of 0.95 for both types of EGD. There was excellent interobserver agreement between endoscopists, regardless of the type of EGD. The severity of hepatic dysfunction and the presence or absence of a history of previous esophageal varices ligation did not have any impact on the accuracy or interobserver agreement. CONCLUSIONS Small-caliber EGD performed under sedation via oral intubation is a highly accurate and reliable modality for evaluating esophageal varices in patients with end-stage liver disease and/or portal hypertension, regardless of the degree of hepatic dysfunction or history of previous esophageal varices ligation.

Abstract
Confocal laser scanning microscopy (CLSM) was used to examine molecules related to the cholinergic neurotransmission system and detected at all the larval stages of Paracentrotus lividus, by histochemical and immunohistochemical methods. CLSM, providing spatial resolution of the cells located both at the larval surface and at depth, allows a complete mapping in a three-dimensional volumetric frame. At early larval stages acetylcholinesterase- as well as choline acetyltransferase-like molecules were found mainly in the gut wall cells, and along the ciliary bands of the arms, together with muscarinic acetylcholine receptors. At perimetamorphic stages, cholinergic molecules were present in the ciliate strands along the arms, in the larval body and in the rudiment. At metamorphosis, positivity to cholinergic molecules translocated to the juvenile, where a high frequency of mAChR- and ChAT-like positive cells was found.

Abstract
BACKGROUND & AIMS Islet amyloid polypeptide (IAPP) levels are elevated in pancreatic cancer and may be a useful marker of pancreatic cancer-associated diabetes. The aim of this study was to compare the sensitivity and specificity for pancreatic cancer of IAPP with that of CA19-9, examine clinical characteristics of diabetes in pancreatic cancer, and define the relationship of IAPP to diabetes of pancreatic cancer. METHODS Fasting serum glucose, IAPP, and CA 19-9 were measured in 130 subjects with pancreatic cancer, 250 subjects with other pancreatic and peripancreatic diseases, and 116 controls. In pancreatic cancer patients, we noted tumor stage and the presence and duration of diabetes. RESULTS IAPP was markedly elevated in pancreatic cancer, especially in patients with diabetes. However, the sensitivity of IAPP for pancreatic cancer was less than that of CA 19-9 (40% vs. 75%; P < 0.001). Diabetes was present in 46% of pancreatic cancers and 55% of resectable tumors. In pancreatic cancer with diabetes, the sensitivity of IAPP was only 50%. In resectable cancer it was 27%. CONCLUSIONS IAPP is elevated in pancreatic cancer but is not sensitive enough to replace or complement existing tests. Diabetes occurs early and frequently in pancreatic cancer. Development of a sensitive and specific marker for pancreatic-associated diabetes might lead to diagnosis of resectable pancreatic cancer.

Abstract
The treatment of NIDDM patients with secondary failure to sulphonylurea is a common problem. We performed a crossover study in 50 NIDDM patients with secondary failure to glibenclamide by comparing the addition to sulphonylurea of either a low-dose bedtime NPH insulin or a t.i.d. oral metformin and by analyzing treatment efficacy in relation to patient and disease characteristics. Both combined therapies clearly improved glycaemic control. HbA1 c were similarly reduced by the addition of either bedtime NPH insulin (7.6+/-0.34 vs 8.7+/-0.35, p<0.01) or metformin (7.6+/-0.22 vs 8.6+/-0.31, p<0.01). Also fasting plasma glucose (FPG) and post-prandial plasma glucose (PPPG) significantly decreased (p<0.01) with both treatments. Bed-time NPH insulin was more effective on FPG reduction than metformin (-36+/-2% vs -25+/-2%, p<0.01); in contrast, metformin addition was more effective on PPPG reduction than bedtime NPH insulin addition (-30+/-2% vs 20+/-3%, p<0.01). Serum cholesterol was marginally but significantly decreased after metformin (5.49+/-0.19 vs 5.91 +/-0.18 mM, p<0.05) but not after NPH insulin. Body weight increase was significantly greater after insulin addition than after metformin (1.47+/-0.25 Kg vs 0.64+/-0.17 p=0.02). All patients preferred the addition of metformin rather than NPH insulin. None of the measured clinical and metabolic variables (before treatment FPG and PPPG, HbA1 c, post-glucagon C-peptide levels, insulin sensitivity, patient age, BMI and diabetes duration) significantly correlated to the efficacy of the two combined treatments studied. In conclusion, in NIDDM patients with secondary failure to sulphonylureas the addition of either low-dose bedtime NPH insulin or t.i.d. metformin is similarly effective in improving glycaemic control. Metformin is better accepted by patients and provides a modest advantage in terms of body weight and cholesterol levels. The most common clinical and metabolic variables are not useful for predicting the efficacy of these two combined treatments.

Abstract
BACKGROUND/AIMS Treatment of pancreatic steatorrhea with porcine lipase is unsatisfactory because it is rapidly denatured by acidic intraluminal conditions. The aim of this study was to determine if bacterial lipase is resistant to acid denaturation and is active in the presence of bile acids by comparing its stability with that of porcine lipase in gastric and duodenal juice obtained from six patients undergoing a cholecystokinin octapeptide pancreatic function test. METHODS After inactivating native lipolytic activity, both juices were altered to simulate fasting and postprandial conditions in normal patients and patients with pancreatic insufficiency. Gastric juice was adjusted to pH 2, 3, 4, or 6, duodenal juice to pH 4 or 6, and bile acid concentrations to 4 or 12 mmol/L. Nutrients were added to one half of the samples. Initial bacterial or porcine lipolytic concentrations were 25 or 250 U/mL. After a 1-hour incubation at 37 degrees C, lipolytic activity was remeasured. RESULTS In gastric juice, more bacterial lipolytic activity survived than porcine lipolytic activity at both concentrations in the absence of nutrients and at a concentration of 25 U/mL with nutrients (P < 0.05). In duodenal juice, more bacterial lipolytic activity survived than porcine activity at pH 4 under all test conditions (P < 0.05). CONCLUSIONS Bacterial lipolytic activity should survive better within the gastrointestinal lumen than porcine lipolytic activity and be more effective to treat steatorrhea.

Abstract
The incidence of type I (insulin-dependent) diabetes was determined in the district of Catania (eastern Sicily) in children under 15 years of age over a 3-year period (1 January 1989 to 31 December 1991). Two independent sources of information were used. The primary source was contact with all medical services in the province, and the secondary source was the personal identification cards issued to all diabetic patients by the National Health System necessary for obtaining free medical care. The information obtained was 99.6% complete. The overall incidence was 10.2/10(5) per year. This study provides the first standardized data on the incidence of type I diabetes in Sicily and is consistent with the possibility of regional deviations from the proposed north to south gradient.

Abstract
OBJECTIVE To evaluate the incidence and symptoms of and risk factors for biliary sludge and gallstones during pregnancy and to assess the natural history of these conditions in the first year after delivery. DESIGN Cohort study. PATIENTS A total of 272 pregnant women recruited in the first trimester. MEASUREMENTS Biliary sludge and gallstones were diagnosed using ultrasonography, both during pregnancy and after delivery. Predictors of the presence or disappearance of sludge and stones were examined. MAIN RESULTS Overall, from the first trimester of pregnancy until the immediate postpartum period, 67 women were newly diagnosed with biliary sludge, and 6 women were newly diagnosed with gallstones. The respective incidence rates were 31% (95% Cl, 25% to 37%) and 2% (95% Cl, 0.2% to 4%). During pregnancy, 28% of women experienced biliary pain, which was associated only with presence of stones. After delivery, 92 women had sludge and 23 had stones. Sludge disappeared in 61% of these women (Cl, 50% to 73%) after a mean follow-up of 5 months, and stones disappeared in 28% of women (Cl, 10% to 46%) after 9.7 months of follow-up. CONCLUSIONS Biliary sludge occurred frequently during pregnancy but was generally asymptomatic and often disappeared spontaneously after delivery. Gallstones were much less frequent and were more likely to be associated with biliary pain.

Abstract
One thousand twenty patients consecutively admitted because of a clinical suspicion of pancreatic cancer were investigated to evaluate the accuracy of simple clinical, laboratory, and ultrasonographic data in the diagnosis of pancreatic cancer. Age, weight loss, recent-onset diabetes mellitus, palpable abdominal mass or gallbladder, elevated serum bilirubin or alkaline phosphatase levels, and ultrasonography were significant criteria in discriminating 80 pancreatic cancers from 940 controls. The most sensitive criteria were ultrasonography (83%), weight loss (66%), and bilirubin level of > 3 mg/dl (61%); the most specific were ultrasonography (99%), recent-onset diabetes (97%), and a distended palpable gallbladder (94%). Only ultrasonography demonstrated an elevated positive predictive value (86%), while weight loss, elevated bilirubin and alkaline phosphatase, besides ultrasonography had an elevated negative predictive value (95%). These results show that advanced pancreatic cancer may be excluded with simple clinical and laboratory data; ultrasonography can confirm the diagnosis with a high degree of accuracy. We suggest that the results of any new diagnostic tests for pancreatic cancer be compared with these clinical findings.
