| 1 | Endoscopic ultrasound guided radiofrequency ablation,for pancreatic cystic neoplasms and neuroendocrine tumors显示文摘AIM: To outline the feasibility, safety, adverse events and early results of endoscopic ultrasound(EUS)-radiofrequency ablation(RFA) in pancreatic neoplasms using a novel probe. METHODS: This is a multi-center, pilot safety feasibility study. The intervention described was radiofrequency ablation(RF) which was applied with an innovative monopolar RF probe(1.2 mm Habib EUS-RFA catheter) placed through a 19 or 22 gauge fine needle aspiration(FNA) needle once FNA was performed in patients with a tumor in the head of the pancreas. The HabibTM EUSRFA is a 1 Fr wire(0.33 mm, 0.013') with a working length of 190 cm, which can be inserted through the biopsy channel of an echoendoscope. RF power is applied to the electrode at the end of the wire to coagulate tissue in the liver and pancreas.RESULTS: Eight patients [median age of 65(range 27-82) years; 7 female and 1 male] were recruited in a prospective multicenter trial. Six had a pancreatic cysticneoplasm(four a mucinous cyst, one had intraductal papillary mucinous neoplasm and one a microcystic adenoma) and two had a neuroendocrine tumors(NET) in the head of pancreas. The mean size of the cystic neoplasm and NET were 36.5 mm(SD ± 17.9 mm) and 27.5 mm(SD ± 17.7 mm) respectively. The EUSRFA was successfully completed in all cases. Among the 6 patients with a cystic neoplasm, post procedure imaging in 3-6 mo showed complete resolution of the cysts in 2 cases, whilst in three more there was a 48.4% reduction [mean pre RF 38.8 mm(SD ± 21.7 mm) vs mean post RF 20 mm(SD ± 17.1 mm)] in size. In regards to the NET patients, there was a change in vascularity and central necrosis after EUS-RFA. No major complications were observed within 48 h of the procedure. Two patients had mild abdominal pain that resolved within 3 d. CONCLUSION: EUS-RFA of pancreatic neoplasms with a novel monopolar RF probe was well tolerated in all cases. Our preliminary data suggest that the procedure is straightforward and safe. The response ranged from complete resolution to a 50% reduction in size. | Madhava Pai Nagy Habib Hakan Senturk Sundeep Lakhtakia Nageshwar Reddy Vito R Cicinnati Iyad Kaba Susanne Beckebaum Panagiotis Drymousis Michel Kahaleh William Brugge | 2015 | World Journal of Gastrointestinal Surgery2015，7，4： | 23 |
| 2 | Contrast-enhanced ultrasound of histologically proven hepatic epithelioid hemangioendothelioma显示文摘AIM: To analyze contrast-enhanced ultrasound(CEUS) features of histologically proven hepatic epithelioid hemangioendothelioma(HEHE) in comparison to other multilocular benign focal liver lesions(FLL).METHODS: Twenty-five patients with histologically proven HEHE and 45 patients with histologically proven multilocular benign FLL were retrospectively reviewed. Four radiologists assessed the CEUS enhancement pattern in consensus.RESULTS: HEHE manifested as a single(n = 3) or multinodular(n = 22) FLL. On CEUS, HEHE showed rim-like(18/25, 72%) or heterogeneous hyperenhancement(7/25, 28%) in the arterial phase and hypoenhancement(25/25, 100%) in the portal venous and late phases(PVLP), a sign of malignancy. Eighteen patients showed central unenhanced areas(18/25, 72%); in seven patients(7/25, 28%), more lesions were detected in the PVLP. In contrast, all patients with hemangioma and focal nodular hyperplasia showed hyperenhancement as the most distinctive feature(P < 0.01).CONCLUSION: CEUS allows for characterization of unequivocal FLL. By analyzing the hypoenhancement in the PVLP, CEUS can determine the malignant nature of HEHE. | Yi Dong Wen-Ping Wang Vito Cantisani Mirko D'Onofrio Andre Ignee Lorenzo Mulazzani Adrian Saftoiu Zeno Sparchez Ioan Sporea Christoph F Dietrich | 2016 | World Journal of Gastroenterology2016，22，19： | 21 |
| 3 | Minimally invasive surgery for gastric cancer: A comparison between robotic, laparoscopic and open surgery显示文摘AIM To investigate the role of minimally invasive surgery for gastric cancer and determine surgical, clinical, and oncological outcomes.METHODS This is a propensity score-matched case-control study, comparing three treatment arms: robotic gastrectomy(RG), laparoscopic gastrectomy(LG), open gastrectomy(OG). Data collection started after sharing a specific study protocol. Data were recorded through a tailored and protected web-based system. Primary outcomes: harvested lymph nodes, estimated blood loss, hospital stay, complications rate. Among the secondary outcomes, there are: operative time, R0 resections, POD of mobilization, POD of starting liquid diet and soft solid diet. The analysis includes the evaluation of type and grade of postoperative complications. Detailed information of anastomotic leakages is also provided.RESULTS The present analysis was carried out of 1026 gastrectomies. To guarantee homogenous distribution of cases, patients in the RG, LG and OG groups were 1:1:2 matched using a propensity score analysis with a caliper = 0.2. The successful matching resulted in a total sample of 604 patients(RG = 151; LG = 151; OG = 302). The three groups showed no differences in all baseline patients characteristics, type of surgery(P = 0.42) and stage of the disease(P = 0.16). Intraoperative blood loss was significantly lower in the LG(95.93 ± 119.22) and RG(117.91 ± 68.11) groups compared to the OG(127.26 ± 79.50, P = 0.002). The mean number of retrieved lymph nodes was similar between the RG(27.78 ± 11.45), LG(24.58 ± 13.56) and OG(25.82 ± 12.07) approach. A benefit in favor of the minimally invasive approaches was found in the length of hospital stay(P < 0.0001). A similar complications rate was found(P = 0.13). The leakage rate was not different(P = 0.78) between groups.CONCLUSION Laparoscopic and robotic surgery can be safely performed and proposed as possible alternative to open surgery. The main highlighted benefit is a faster postoperative functional recovery. | Amilcare Parisi Daniel Reim Felice Borghi Ninh T Nguyen Feng Qi Andrea Coratti Fabio Cianchi Maurizio Cesari Francesca Bazzocchi Orhan Alimoglu Johan Gagnière Graziano Pernazza Simone D'Imporzano Yan-Bing Zhou Juan-Santiago Azagra Olivier Facy Steven T Brower Zhi-Wei Jiang Lu Zang Arda Isik Alessandro Gemini Stefano Trastulli Alexander Novotny Alessandra Marano Tong Liu Mario Annecchiarico Benedetta Badii Giacomo Arcuri Andrea Avanzolini Metin Leblebici Denis Pezet Shou-Gen Cao Martine Goergen Shu Zhang Giorgio Palazzini Vito D'Andrea Jacopo Desiderio | 2017 | World Journal of Gastroenterology2017，23，13： | 17 |
| 4 | Non-surgical treatment of esophageal achalasia显示文摘Esophageal achalasia is an infrequent motility disorder characterized by a progressive stasis and dilation of the oesophagus; with subsequent risk of aspiration, weight loss, and malnutrition. Although the treatment of achalasia has been traditionally based on a surgical approach, especially with the introduction of laparoscopic techniques, there is still some space for a medical approach. The present article reviews the non-surgical therapeutic options for achalasia. | Vito Annese Gabrio Bassotti | 2006 | World Journal of Gastroenterology2006，12，36： | 16 |
| 5 | Liver metastases:Contrast-enhanced ultrasound compared with computed tomography and magnetic resonance显示文摘The development of ultrasound contrast agents with excellent tolerance and safety profiles has notably improved liver evaluation with ultrasound(US)for several applications,especially for the detection of metastases.In particular,contrast enhanced ultrasonography(CEUS)allows the display of the parenchymal microvasculature,enabling the study and visualization of the enhancement patterns of liver lesions in real time and in a continuous manner in all vascular phases,which is similar to contrast-enhanced computed tomography(CT)and contrast-enhanced magnetic resonance imaging.Clinical studies have reported that the use of a contrast agent enables the visualization of more metastases with significantly improved sensitivity and specificity compared to baseline-US.Furthermore,studies have shown that CEUS yields sensitivities comparable to CT.In this review,we describe the state of the art of CEUS for detecting colorectal liver metastases,the imaging features,the literature reports of metastases in CEUS as well as its technique,its clinical role and its potential applications.Additionally,the updated international consensus panel guidelines are reported in this review with the inherent limitations of this technique and best practice experiences. | Vito Cantisani Hektor Grazhdani Cristina Fioravanti Maria Rosignuolo Fabrizio Calliada Daniela Messineo Maria Giulia Bernieri Adriano Redler Carlo Catalano Ferdinando D’Ambrosio | 2014 | World Journal of Gastroenterology2014，20，29： | 16 |
| 6 | Molecular targeting agents associated with transarterial chemoembolization or radiofrequency ablation in hepatocarcinoma treatment显示文摘Hepatocellular carcinoma(HCC)is the fifth most common cause of cancer in the world.According to Barcelona Clinic Liver Cancer modified criteria,patients with early stage disease are candidate to radiofrequency ablation(RFA),while patients with intermediate stage HCC are usually treated by transarterial chemoembolization(TACE).TACE and RFA induce a transient devascularisation effect followed by strong neoangiogenic stimulus.In fact,after these procedures,it has been demonstrated an up-regulation of pro-angiogenic and growth factors such as vascular endothelial growth factor-A,which might contribute to accelerated progression in patients with incomplete response.Several studies have demonstrated that MAP-kinase and AKT pathways,in addition to neo-angiogenesis,have an important role in the development of HCC.In advanced HCC,anti-angiogenic therapy and tyrosine kinases inhibitors showed potential clinical benefit.Actually,a number of clinical studies are ongoing testing these agents in combination with TACE or RFA.In this paper,we have reviewed the most recent preclinical and clinical results of such trials. | Girolamo Ranieri Ilaria Marech Vito Lorusso Veronica Goffredo Angelo Paradiso Domenico Ribatti Cosmo Damiano Gadaleta | 2014 | World Journal of Gastroenterology2014，20，2： | 14 |
| 7 | Innovative surgical approaches for hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is the sixth most common cancer worldwide,with an increasing diffusion in Europe and the United States.The management of such a cancer is continuously progressing and the objective of this paper is to evaluate innovation in the surgical treatment of HCC.In this review,we will analyze the modern concept of preoperative management,the role of laparoscopic and robotic surgery,the intraoperative use of three dimensional models and augmented reality,as well as the potential application of fluorescence. | Riccardo Memeo Nicola de’Angelis Vito de Blasi Zineb Cherkaoui Oronzo Brunetti Vito Longo Tullio Piardi Daniele Sommacale Jacques Marescaux Didier Mutter Patrick Pessaux | 2016 | World Journal of Hepatology2016，8，13： | 13 |
| 8 | Role of blood AFP mRNA and tumor grade in the preoperative prognostic evaluation of patients with hepatoceiluiar carcinoma显示文摘AIM: To explore the potential prognostic role of preoperative tumor grade and blood AFP mRNA in a cohort of patients with hepatocellular carcinoma (HCC)eligible for radical therapies according to a well-defined treatment algorithm not including nodule size and number as absolute selection criteria.METHODS: Fifty patients with a diagnosis of HCC were prospectively enrolled in the study. Inclusion criteria were: (1) histological assessment of tumor grade by means of percutaneous biopsies; (2) determination of AFP mRNA status in the blood; (3) patient's eligibility for radical therapies.RESULTS: At preoperative evaluation, 54% of the study group had a well-differentiated HCC, 42% had AFP mRNA in the blood, 40% had a tumor larger than 5 cm and 56% had more than one nodule. Surgery (resection or liver transplantation) was performed in 29 patients,while 21 had percutaneous ablation procedures. After a median follow-up of 28 mo, 12-, 24-, and 36-mo survival rates were 78%, 58%, and 51%, respectively. Surgical therapy, performance status and three tumor-related variables (AFP mRNA, HCC grade and gross vascular invasion) resulted as significant survival predictors at univariate analysis. Nodule size and number did not perform as significant prognosticators. Multivariate study selected only surgical therapy and a biologically early HCC profile (AFP mRNA negative and well-differentiated tumor without gross vascular invasion) as independent survival variables.CONCLUSION: The preoperative determination of tumor grade and blood AFP mRNA status may potentially refine the prognostic evaluation of HCC patients and improve the selection process for radical therapies. | Umberto Cillo Alessandro Vitale Filippo Navaglia Daniela Basso Umberto Montin Marco Bassanello Francesco D'Amico Francesco Antonio Ciarleglio Alberto Brolese Giacomo Zanus Vito De Pascale Mario Plebani Davide Francesco D'Amico | 2005 | World Journal of Gastroenterology2005，11，44： | 12 |
| 9 | Comparison of the diagnostic yield and outcomes between standard 8 h capsule endoscopy and the new 12 h capsule endoscopy for investigating small bowel pathology显示文摘AIM: To evaluate the completion rate and diagnostic yield of the Pill Cam SB2-ex in comparison to the Pill Cam SB2.METHODS:Two hundred cases using the 8-h Pill Cam SB2 were retrospectively compared to 200 cases using the 12 h Pill Cam SB2-ex at a tertiary academic center.Endoscopically placed capsules were excluded from the study.Demographic information,indications for capsule endoscopy,capsule type,study length,completion of exam,clinically significant findings,timestamp of most distant finding,and significant findings beyond 8 h were recorded.RESULTS:The 8 and 12 h capsule groups were well matched respectively for both age(70.90±14.19vs 71.93±13.80,P=0.46)and gender(45.5%vs48%male,P=0.69).The most common indications for the procedure in both groups were anemia and obscure gastrointestinal bleeding.Pill Cam SB2-ex had a significantly higher completion rate than Pill Cam SB2(88%vs 79.5%,P=0.03).Overall,the diagnostic yield was greater for the 8 h capsule(48.5%for SB2vs 35%for SB2-ex,P=0.01).In 4/70(5.7%)of abnormal SB2-ex exams the clinically significant findingwas noted in the small bowel beyond the 8 h mark.CONCLUSION:In our study,we found the Pill Cam SB2-ex to have a significantly increased completion rate,though without any improvement in diagnostic yield compared to the Pill Cam SB2. | Merajur Rahman Stuart Akerman Bethany De Vito Larry Miller Meredith Akerman Keith Sultan | 2015 | World Journal of Gastroenterology2015，21，18： | 12 |
| 10 | untreatable hepatocellular 癌的自然历史: 回顾的队研究显示文摘 AIM:To investigate the clinical course of untreatable hepatocellular carcinoma(HCC) identified at any stage and to identify factors associated with mortality.METHODS:From January 1999 to December 2010,320 out of 825 consecutive patients with a diagnosis of HCC and not appropriate for curative or palliative treatments were followed and managed with supportive therapy.Cirrhosis was diagnosed by histological or clinical features and liver function was evaluated according to Child-Pugh score.The diagnosis of HCC was performed by Ultra-Sound guided biopsy or by multiphasic contrast-enhanced computed tomography or gadolinium-enhanced magnetic resonance imaging.Data were collected for each patient including all clinical,laboratory and imaging variables necessary for the outcome prediction staging systems considered.HCC staging was performed according Barcelona Clinic Liver Cancer(BCLC) and Cancer of the Liver Italian Program scores.Follow-up time was defined as the number of months from the diagnosis of HCC to death.Prognostic baseline variables were analyzed by multivariate Cox analysis to identify the independent predictors of survival.RESULTS:Seventy-five per cent of patients had hepatitis C.Ascites was present in 169 patients(53%),while hepatic encephalopathy was present in 49 patients(15%).The Child-Pugh score was class A in 105 patients(33%),class B in 142 patients(44%),and class C in 73 patients(23%).One hundred patients(31%) had macroscopic vascular invasion and/or extrahepatic spread of the tumor.A single lesion > 10 cm was observed in 34 patients(11%),while multinodular HCC was present in 189 patients(59%).Thirty nine patients(12%) were BCLC early(A) stage,55(17%) were BCLC intermediate(B) stage,124(39%) were BCLC advanced(C) stage,and 102(32%) were endstage BCLC(D).At the time of this analysis(July 2011),28(9%) patients were still alive.Six(2%) patients who were lost during follow-up were censored at the last visit.The overall median survival was 6.8 mo,and the 1-year survival was 32%.The 1-year survival according to BCLC classes was 100%,79%,12% and 0%,for BCLC A,B,C and D,respectively.There was a significant difference in survival between each BCLC class.The median survival of patients of BCLC stages A,B,C and D was 33,17.4,6.9,and 1.8 mo,respectively(P < 0.05 for comparison between stages).The median survival of Child-Pugh A,B and C classes were 9.8 mo(range 6.4-13),6.1(range 4.9-7.3),and 3.7(range 1.5-6),respectively(P < 0.05 for comparison between stages).By univariate analysis,the variables significantly associated to an increased liklihood of mortality were Eastern Cooperative Oncology Group performance status(PS),presence of ascites,low level of albumin,elevated level of bilirubin,international normalized ratio(INR) and Log-[(α fetoprotein(AFP)].At multivariate analysis,mortality was independently predicted by bad PS(P < 0.0001),high INR values(P = 0.0001) and elevated Log-(AFP) levels(P = 0.009).CONCLUSION:This study confirms the heterogeneous behavior of untreated HCC.BCLC staging remains an important prognostic guide and may be important in decision-making for palliative treatment. | Giuseppe Cabibbo Marcello Maida Chiara Genco Pietro Parisi Marco Peralta Michela Antonucci Giuseppe Brancatelli Calogero Cammà Antonio Craxì Vito Di Marco | 2012 | World Journal of Hepatology2012，4，9： | 11 |
| 11 | Gastrointestinal motility disorders in inflammatory bowel diseases显示文摘The relationship between motility and inflammatory gastrointestinal disorders is at the same time complex and intriguing since these conditions might share some genetic,environmental,immunological and microbial predisposing factors.In addition,significant symptom overlapping may occur,muddling the waters within the clinical context.Although on one hand this represents a challenge for the clinician for a potential under-or over-treatment and diagnostic delay,on the other hand it possibly represents an opportunity for the researcher to better disclose the intimate relationship between chronic(often low-grade)inflammation,motor disorders and deranged sensory function.The best example is probably represented by Crohn’s disease and ulcerative colitis.In fact,a number of gastrointestinal motor disorders have been described in association with these diseases,disorders which span from the esophagus to the anorectum,and which will be extensively covered in this review.It is conceivable that at least part of this derangement is strictly related to inflammatory cytokine trafficking and neuromuscular changes;however,given the high prevalence of functional gastrointestinal disorders in the general population,this overlap might also be serendipitous.However,it is worth noting that literature data on this topic are relatively scarce,sometimes quite outdated,and mostly focused on the interplay between irritable bowel syndrome and inflammatory bowel disease.Nevertheless,both researchers and clinicians must be aware that symptoms related to gastrointestinal motility disorders may be highly prevalent in both active and inactive inflammatory bowel disease,correlate with greater psychological comorbidity and poorer quality of life,and may negatively influence the therapeutic approaches. | Gabrio Bassotti Elisabetta Antonelli Vincenzo Villanacci Marianna Salemme Manuela Coppola Vito Annese | 2014 | World Journal of Gastroenterology2014，20，1： | 11 |
| 12 | Label-free sensing of ultralow-weight molecules with all-dielectric metasurfaces supporting bound states in the continuum显示文摘The realization of an efficient optical sensor based on a photonic crystal metasurface supporting bound states in the continuum is reported. Liquids with different refractive indices, ranging from 1.4000 to 1.4480, are infiltrated in a microfluidic chamber bonded to the sensing dielectric metasurface. A bulk liquid sensitivity of 178 nm/RIU is achieved, while a Q-factor of about 2000 gives a sensor figure of merit up to 445 in air at both visible and infrared excitations. Furthermore, the detection of ultralow-molecular-weight(186 Da) molecules is demonstrated with a record resonance shift of 6 nm per less than a 1 nm thick single molecular layer. The system exploits a normal-to-the-surface optical launching scheme, with excellent interrogation stability and demonstrates alignment-free performances, overcoming the limits of standard photonic crystals and plasmonic resonant configurations. | SILVIA ROMANO GIANLUIGI ZITO STEFANIA TORINO GIUSEPPE CALAFIORE ERIKA PENZO GIUSEPPE COPPOLA STEFANO CABRINI IVO RENDINA VITO MOCELLA | 2018 | Photonics Research2018，6，7： | 9 |
| 13 | Food allergy in gastroenterologic diseases:Review of literature显示文摘Food allergy is a common and increasing problem worldwide. The newly-found knowledge might provide novel experimental strategies, especially for laboratory diagnosis. Approximately 20% of the population alters their diet for a perceived adverse reaction to food, but the application of double-blind placebo-controlled oral food challenge, the “gold standard” for diagnosis of food allergy, shows that questionnaire-based studies over- estimate the prevalence of food allergies. The clinical disorders determined by adverse reactions to food can be classified on the basis of immunologic or nonimmu- nologic mechanisms and the organ system or systems affected. Diagnosis of food allergy is based on clinical history, skin prick tests, and laboratory tests to detect serum-food specific IgE, elimination diets and challeng- es. The primary therapy for food allergy is to avoid the responsible food. Antihistamines might partially relieve oral allergy syndrome and IgE-mediated skin symptoms, but they do not block systemic reactions. Systemic cor- ticosteroids are generally effective in treating chronic IgE-mediated disorders. Epinephrine is the mainstay of treatment for anaphylaxis. Experimental therapies for IgE-mediated food allergy have been evaluated, such as humanized IgG anti-IgE antibodies and allergen specific immunotherapy. | Pasquale Mansueto Giuseppe Montalto Maria Luisa Pacor Maria Esposito-Pellitteri Vito Ditta Claudia Lo Bianco Stefania Maria Leto-Barone Gabriele Di Lorenzo | 2006 | World Journal of Gastroenterology2006，12，48： | 7 |

| 15 | Aetiology of Legg-Calvé-Perthes disease:A systematic review显示文摘BACKGROUND Legg-Calvé-Perthes disease(LCPD) is a clinical condition affecting the femoral head of children during their growth. Its prevalence is set to be between 0.4/100000 to 29.0/100000 children less than 15 years of age with a peak of incidence in children aged from 4 years to 8 years. LCPD aetiology has been widely studied, but it is still poorly understood.AIM To analyse the available literature to document the up-to-date evidence on LCPD aetiology.METHODS A systematic review of the literature was performed regarding LCPD aetiology,using the following inclusion criteria: studies of any level of evidence, reporting clinical or preclinical results and dealing with the aetiology or pathogenesis of LCPD. Two reviewers searched the PubMed and Science Direct databases from their date of inception to the 20th of May 2018 in accordance with the Preferred Reporting Items for Systemic Reviews and Meta-Analyses guidelines. To achieve the maximum sensitivity of the search strategy, we combined the terms: ‘‘Perthes disease OR LCPD OR children avascular femoral head necrosis' with 'pathology OR aetiology OR biomechanics OR genetics' as either key words or MeSH terms.RESULTS We include 64 articles in this review. The available evidence on LCPD aetiology is still debated. Several hypotheses have been researched, but none of them was found decisive. While emerging evidence showed the role of environmental risk factors and evidence from twin studies did not support a major role for genetic factors, a congenital or acquired predisposition cannot be excluded in disease pathogenesis. One of the most supported theories involved mechanical induced ischemia that evolved into avascular necrosis of the femoral head in sensible patients.CONCLUSION The literature available on the aetiology of LCPD presents major limitations in terms of great heterogeneity and a lack of high-profile studies. Although a lot of studies focused on the genetic, biomechanical and radiological background of the disease, there is a lack of consensus on one or multiple major actors of the etiopathogenesis. More studies are needed to understand the complex and multifactorial genesis of the avascular necrosis characterizing the disease. | Vito Pavone Emanuele Chisari Andrea Vescio Claudio Lizzio Giuseppe Sessa Gianluca Testa | 2019 | World Journal of Orthopedics2019，10，3： | 7 |
| 16 | Hyperferritinemia is a risk factor for steatosis in chronic liver disease显示文摘AIM: To investigate the relationship between ferritin and steatosis in patients with chronically abnormal liver function tests (LFTs) and high ferritin level. METHODS: One hundred and twenty-four consecutive patients with hyperferritinemia (male > 300 ng/mL, female > 200 ng/mL) were evaluated; clinical, biochemical and serological data, iron status parameters, HFE gene mutations and homeostasis model assessment score were obtained. Steatosis was graded by ultrasound as absent or present. Histology was available in 53 patients only. RESULTS: Mean level of ferritin was 881 ± 77 ng/mL in men and 549 ± 82 ng/mL in women. The diagnosis was chronic hepatitis C in 53 (42.7%), non-alcoholic fatty liver disease/non-alcoholic steatohepatitis in 57 (45.9%), and cryptogenic liver damage in 14 (11.3%). None was diagnosed as hereditary hemochromatosis (HH). Hepatic siderosis on liver biopsy was present in 17 of 54 (32%) patients; grade 1 in eight and grade 2 in nine. Overall, 92 patients (74.2%) had steatosis. By logistic regression, ferritin and γ-glutamyltransferase were independent predictors of steatosis. Ferritin levels were signifi cantly related to low platelet count, steatosis and hepatitis C virus infection. CONCLUSION: In a non-obese cohort of non-alcoholic patients with chronically abnormal LFTs without HH, high serum ferritin level is a risk factor for steatosis. | Anna Licata Maria Elena Nebbia Giuseppe Cabibbo Giovanna Lo Iacono Francesco Barbaria Virna Brucato Nicola Alessi Salvatore Porrovecchio Vito Di Marco Antonio Craxì Calogero Cammà | 2009 | World Journal of Gastroenterology2009，15，17： | 6 |

| 18 | Pediatric nonalcoholic fatty liver disease:A clinical and laboratory challenge显示文摘The true prevalence of pediatric nonalcoholic fatty liver disease (NAFLD) is unknown. Challenges in determin ing the population prevalence of NAFLD include the type of test (and the reference intervals used to define normal and abnormal), the type of population (general population, hospital series), the demographic characteristics of the population sampled, and the nat ure of the study design. The natural history of pediat ric NAFLD remains uncertain. The issue of when to perform a liver biopsy in children with suspected NAFLD remains controversial. Children with NAFLD but normal alanine aminotransferase are rarely investigated. However, evidence of alterations in glucose metabolism parameters should prompt a better understanding of the natural history of pediatric NAFLD not only in terms of the progression of liver disease but also regarding its potential relationship with other health outcomes such as type 2 diabetes mellitus and cardiovascular disease. This evidence could make liver biopsy mandatory in the majority of cases at risk of progressive and severe hepatic and extrahepatic disease. This conclusion, however, raises the question of the feasibility of liver biopsy assessment in an extremely large at risk popul ation, and of the cost/effectiveness of this policy. There is a considerable, continuous interest in reliable, noninv asive alternatives that will allow the prognosis of pediat ric NAFLD to be followed in large community or populat ionbased studies. | Lucia Pacifico Eleonora Poggiogalle Vito Cantisani Guendalina Menichini Paolo Ricci Flavia Ferraro Claudio Chiesa | 2010 | World Journal of Hepatology2010，2，7： | 6 |
| 19 | Endowing a plain fluidic chip with micro-optics: a holographic microscope slide显示文摘Lab-on-a-Chip(LoC)devices are extremely promising in that they enable diagnostic functions at the point-of-care.Within this scope,an important goal is to design imaging schemes that can be used out of the laboratory.In this paper,we introduce and test a pocket holographic slide that allows digital holography microscopy to be performed without an interferometer setup.Instead,a commercial off-the-shelf plastic chip is engineered and functionalized with this aim.The microfluidic chip is endowed with micro-optics,that is,a diffraction grating and polymeric lenses,to build an interferometer directly on the chip,avoiding the need for a reference arm and external bulky optical components.Thanks to the single-beam scheme,the system is completely integrated and robust against vibrations,sharing the useful features of any common path interferometer.Hence,it becomes possible to bring holographic functionalities out of the lab,moving complexity from the external optical apparatus to the chip itself.Label-free imaging and quantitative phase contrast mapping of live samples are demonstrated,along with flexible refocusing capabilities.Thus,a liquid volume can be analyzed in one single shot with no need for mechanical scanning systems. | Vittorio Bianco Biagio Mandracchia Valentina Marchesano Vito Pagliarulo Federico Olivieri Sara Coppola Melania Paturzo Pietro Ferraro | 2017 | Light(Science & Applications)2017，6，1： | 6 |
| 20 | Comparison of four proton pump inhibitors for the short-term treatment of esophagitis in elderly patients显示文摘AIM: To compare efficacy and tolerability of four proton pump inhibitors (PPIs) commonly used in the short-term therapy of esophagitis in elderly patients.METHODS: A total of 320 patients over 65 years with endoscopically diagnosed esophagitis were randomly assigned to one of the following treatments for 8 wk: (1) omeprazole 20 mg/d; (2) lansoprazole 30 mg/d; (3) pantoprazole 40 mg/d, or (4) rabeprazole 20 mg/d. Major symptoms, compliance, and adverse events were recorded. After 8 wk, endoscopy and clinical evaluation were repeated.RESULTS: Per protocol and intention to treat healing rates of esophagitis were: omeprazole = 81.0% and 75.0%, lansoprazole = 90.7% (P = 0.143 vs omeprazole) and 85.0%, pantoprazole = 93.5% (P = 0.04 vs omeprazole) and 90.0% (P = 0.02 vs omeprazole), rabeprazole = 94.6% (P = 0.02 vs omeprazole) and 88.8% (P = 0.04 vs omeprazole). Dividing patients according to the grades of esophagitis, omeprazole was significantly less effective than the three other PPIs in healing grade 1 esophagitis (healing rates: 81.8% vs 100%, 100% and 100%, respectively, P = 0.012). Pantoprazole and rabeprazole (100%) were more effective vs omeprazole (89.6%, P = 0.0001)and lansoprazole (82.4%, P = 0.0001) in decreasing heartburn. Pantoprazole and rabeprazole (92.2% and 90.1%, respectively) were also more effective vs lansoprazole (75.0%, P < 0.05) in decreasing acid regurgitation. Finally, pantoprazole and rabeprazole (95.2% and 100%) were also more effective vs lansoprazole (82.6%, P < 0.05) in decreasing epigastric pain.CONCLUSION: In elderly patients, pantoprazole and rabeprazole were significantly more effective than omeprazole in healing esophagitis and than omeprazole or lansoprazole in improving symptoms. H pylori infection did not influence the healing rates of esophagitis after a short-term treatment with PPI. | Alberto Pilotto Marilisa Franceschi Gioacchino Leandro Carlo Scarcelli Luigi Piero D'Ambrosio Francesco Paris Vito Annese Davide Seripa Angelo Andriulli Francesco Di Mario | 2007 | World Journal of Gastroenterology2007，13，33： | 5 |
