4Intraductal papillary neoplasm of the bile ducts: A case report and literature review显示文摘Intraductal papillary neoplasm of the bile duct(IPNB) is a rare bile duct neoplasm mostly found in far eastern nations where hepatolithiasis and clonorchiasis infections are endemic. In western countries,it is very rare and the etiology is unknown. In this article,we report the first IPNB patient we encountered in our clinic and a literature review. The patient is a 38-yearold female with a history of choledocholithiasis who presented with obstructive jaundice. She was found to have a papillary mass at the junction of the right hepatic duct and common hepatic duct with six masses in the liver parenchyma. The immunophenotypic and histologic features of the tumor are consistent with IPNB,gastric subtype. The patient had a partial hepatectomy and has been receiving palliative chemotherapy. In a search of Pub Med database,we collected 354 IPNB patients reported in 22 articles. In these patients,52.8% were from Japan and 27.7% were from western countries including the United States(11.0%). The age of the patients ranged from 35 to 80 years old with an average of 64.6. Male/female ratio was 1.5. Macroscopically,57.5% of the tumors were in the left lobe and 29.5% were in the right lobe. The average size of the tumor were 4.2 cm at the time of diagnosis. Histologically,pancreato-biliary subtype accounted for 41.8%,intestinal 28.0%,gastric 13.5% and oncocytic 16%. An invasive component is most often present in the pancreato-biliary and gastric subtypes. Despite recent advanced technologies,diagnosis of IPNB is still challenging,especially in western countries due to its rarity. Defined clinicopathologic features are in demand for the accurate diagnosis and proper treatment.Yaohong Tan Clara Milikowski Yanelba Toribio Adam Singer Claudia P Rojas Monica T Garcia-Buitrago 2015World Journal of Gastroenterology2015,21,43:19
5Some Suggested Future Directions ofQuantitative Resource Assessments显示文摘Future quantitative assessments will be expected to estimate quantities, values, and locations of undiscovered mineral resources in a form that conveys both economic viability and uncertainty associated with the resources. Historically, declining metal prices point to the need for larger deposits over time. Sensitivity analysis demonstrates that the greatest opportunity for reducing uncertainty in assessments lies in lowering uncertainty associated with tonnage estimates. Of all errors possible in assessments, these affecting tonnage estimates are by far the most important. Selecting the correct deposit model is the most important way of controlling errors because of the dominance of tonnage-deposit models are the best known predictors of tonnage. Much of the surface is covered with apparently barren rocks and sediments in many large regions. Because many exposed mineral deposits are believed to have been found, a prime concern is the presence of possible mineralized rock under cover. Assessments of areas with resources under cover must rely on extrapolation from surrounding areas, new geologic maps of rocks under cover, or analogy with other well-explored areas that can be considered training tracts. Cover has a profound effect on uncertainty and on methods and procedures of assessments because geology is seldom known and geophysical methods typically have attenuated responses. Many earlier assessment methods were based on relationships of geochemical and geophysical variables to deposits learned from deposits exposed on the surface-these will need to be relearned based on covered deposits. Mineral-deposit models are important in quantitative resource assessments for two reasons: (1) grades and tonnages of most deposit types are significantly different, and (2) deposit types are present in different geologic settings that can be identified from geologic maps. Mineral-deposit models are the keystone in combining the diverse geoscience information on geology, mineral occurrences, geophysics, and geochemistry used in resource assessments and mineral exploration. Grade and tonnage models and development of quantitative descriptive, economic, and deposit density models will help reduce the uncertainty of these new assessments.Singer Donald A U. S.

6Physical rehabilitation for lung transplant candidates and recipients: An evidence-informed clinical approach显示文摘Physical rehabilitation of lung transplant candidates and recipients plays an important in optimizing physical function prior to transplant and facilitating recovery of function post-transplant. As medical and surgical interventions in lung transplantation have evolved over time, there has been a demographic shift of individuals undergoing lung transplantation including older individuals, those with multiple co-morbidites, and candidates with respiratory failure requiring bridging to transplantation. These changes have an impact on the rehabilitation needs of lung transplant candidates and recipients. This review provides a practical approach to rehabilitation based on research and clinical practice at our transplant centre. It focuses on functional assessment and exercise prescription during an uncomplicated and complicated clinical course in the pre-transplant, early and late post-transplant periods. The target audience includes clinicians involved in pre- and posttransplant patient care and rehabilitation researchers.Lisa Wickerson Dmitry Rozenberg Tania Janaudis-Ferreira Robin Deliva Vincent Lo Gary Beauchamp Denise Helm Chaya Gottesman Polyana Mendes Luciana Vieira Margaret Herridge Lianne G Singer Sunita Mathur 2016World Journal of Transplantation2016,6,3:8
7ABCD^(2) risk score does not predict the presence of cerebral microemboli in patients with hyper-acute symptomatic critical carotid artery stenosis显示文摘Introduction:ABCD^(2) risk score and cerebral microemboli detected by transcranial Doppler(TCD)have been separately shown to the predict risk of recurrent acute stroke.We studied whether ABCD2 risk score predicts cerebral microemboli in patients with hyper-acute symptomatic carotid artery stenosis.Participants and methods:We studied 206 patients presenting within 2 weeks of transient ischaemic attack or minor stroke and found to have critical carotid artery stenosis(≥50% ).86 patients(age 70±1(SEM:years),58 men,83 Caucasian)had evidence of microemboli;72(84% )of these underwent carotid endarterectomy(CEA).120 patients(age 72±1 years,91 men,113 Caucasian)did not have microemboli detected;102(85% )of these underwent CEA.Data were analysed using X2 and Mann–Whitney U tests and receiver operating characteristic(ROC)curves.Results:140/206(68% :95% CI 61.63 to 74.37)patients with hyper-acute symptomatic critical carotid stenosis had an ABCD2 risk score≥4.There was no significant difference in the NICE red flag criterion for early assessment(ABCD^(2) risk score≥4)for patients with cerebral microemboli versus those without microemboli(59/86 vs 81/120 patients:OR 1.05 ABCD2 risk score≥4(95% CI 0.58 to 1.90,p=0.867)).The ABCD2 risk score was<4 in 27 of 86(31% :95% CI 21 to 41)embolising patients and in 39 of 120(31% :95% CI 23 to 39)without cerebral microemboli.After adjusting for pre-neurological event antiplatelet treatment(APT),area under the curve(AUC)of ROC for ABCD2 risk score showed no prediction of cerebral microemboli(no pre-event APT,n=57:AUC 0.45(95% CI 0.29 to 0.60,p=0.531);preevent APT,n=147:AUC 0.51(95% CI 0.42 to 0.60,p=0.804)).Conclusions:The ABCD2 score did not predict the presence of cerebral microemboli or carotid disease in over one-quarter of patients with symptomatic critical carotid artery stenosis.On the basis of NICE guidelines(refer early if ABCD2≥4),assessment of high stroke risk based on ABCD2 scoring may lead to inappropriate delay in urgent treatment in many patients.Mahmud Saedon Charles E Hutchinson Christopher H E Imray Donald R J Singer 2017Stroke & Vascular Neurology2017,2,2:6
8CT diagnosis of recurrence after pancreatic cancer:Is there a pattern?显示文摘AIM:To investigate predilection sites of recurrence of pancreatic cancer by computed tomography(CT)in follow-up after surgery. METHODS:Seventy seven patients with recurrence after pancreatic cancer surgery were retrospectively identified.The operative technique,R-status,T-stage and development of tumor markers were evaluated. Two radiologists analyzed CT scans with consensus readings.Location of local recurrence,lymph node recurrence and organ metastases were noted.Surgery and progression of findings on follow-up CT were con-sidered as reference standard. RESULTS:The mean follow-up interval was 3.9± 1.8 mo,with a mean relapse-free interval of 12.9± 10.4 mo.The predominant site of recurrence was local (65%),followed by lymph node(17%),liver metastasis (11%)and peritoneal carcinosis(7%).Local recurrence emerged at the superior mesenteric artery(n=28),the hepatic artery(n=8),in an area defined by the surrounding vessels:celiac trunk,portal vein,inferior vena cava(n=22),and in a space limited by the mesenteric artery,portal vein and inferior vena cava(n=17). Lymph node recurrence occurred in the mesenteric root and left lateral to the aorta.Recurrence was confirmed by surgery(n=22)and follow-up CT(n=55).Tumor markers[carbohydrate antigen 19-9(CA19-9),carcinoembryonic antigen(CEA)]increased in accordance with signs of recurrence in most cases(86%CA19-9;79.2% CEA). CONCLUSION:Specific changes of local and lymph node recurrence can be found in the course of the cardinal peripancreatic vessels.The superior mesenteric artery is the leading structure for recurrence.Tobias Heye Nicola Zausig Miriam Klauss Reinhard Singer Jens Werner Gtz Martin Richter Hans-Ulrich Kauczor Lars Grenacher 2011World Journal of Gastroenterology2011,17,9:6
9Prospective evaluation of small bowel preparation with bisacodyl and sodium phosphate for capsule endoscopy显示文摘AIM: To determine the effect of Prepacol?, a com- bination of sodium phosphate and bisacodyl, on transit and quality of capsule endoscopy (CE). METHODS: Fivety two consecutive patients were included in this prospective study. CE was performed following a 12 h fasting period. Twenty six patients were randomized for additional preparation with Prepacol?. The quality of CE was assessed separately for the proximal and the distal small bowel by 3 experienced endoscopists on the basis of a graduation which was initially developed with 20 previous CE. RESULTS: Preparation with Prepacol? accelerated small bowel transit time (262 ± 55 min vs 287 ± 97 min), but had no effect on the quality of CE. Visibility was significantly reduced in the distal compared to the proximal small bowel. CONCLUSION: The significantly reduced visibility of CE in the distal small bowel allocates the need for a good preparation. Since Prepacol? has no beneficial effect on CE the modality of preparation and the ideal time of application remains unclear. Further standardized examinations are necessary to identify sufficient preparation procedures and to determine the impact of the volume of the preparation solution.Andreas Franke Frank Hummel Phillip Knebel Christoph Antoni Ulrich Bcker Manfred V Singer Matthias Lhr 2008World Journal of Gastroenterology2008,14,13:5

11Enhanced expression of interleukin-18 in serum and pancreas of patients with chronic pancreatitis显示文摘AIM: To investigate interleukin-18 (IL-18) in patients with chronic panreatitis (CP). METHODS: We studied 29 patients with CP and 30 healthy controls. Peripheral blood mononuclear cells (PBMC) were isolated and incubated with 50 mmol/L ethanol, lipopolysaccharide (LPS) (doses 25 g/L, 250 g/L, 2500 g/L) and both agents for 24 h. Levels of IL-18 in the supernatants, and levels of IL-18, IL-12, interferon (IFN)-γ and soluble CD14 in the serum were analysed by ELISA technique. Expression of IL-18 in PBMC was investigated by reverse-transcription (RT)-PCR. IL-18 protein levels in CP tissue and in normal pancreas were studied by ELISA technique. IL-18 levels in PBMC and pancreatic tissue were determined by Westernblot. Im-munohistochemistry for pancreatic IL-18 expression was performed. RESULTS: In patients, IL-18 serum levels were signifi-cantly enhanced by 76% (mean: 289.9 ± 167.7 ng/L) compared with controls (mean: 165.2 ± 43.6 ng/L; P < 0.0005). IL-12 levels were enhanced by 25% in patients (18.3 ± 7.3 ng/L) compared with controls (14.7 ± 6.8ng/L, P = 0.0576) although not reaching the statistical significance. IFN-γ and soluble CD14 levels were not in-creased. In vitro, LPS stimulated significantly and dose-dependently IL-18 secretion from PBMC. Incubation with ethanol reduced LPS-stimulated IL-18 secretion by about 50%. The mRNA expression of IL-18 in PBMC and the response of PBMC to ethanol and LPS was similar in CP patients and controls. In PBMC, no significant differences in IL-18 protein levels were detected between patients and controls. IL-18 protein levels were increased in CP tissues compared to normal pancreatic tissues. IL-18 was expressed by pancreatic acinar cells and by infiltrating inflammatory cells within the pancreas. CONCLUSION: IL-18 originates from the chronically inflammed pancreas and appears to be involved in the fibrotic destruction of the organ.Alexander Schneider Stephan L Haas Ralf Hildenbrand Sren Siegmund Iris Reinhard Helmut Nakovics Manfred V Singer Peter Feick 2006World Journal of Gastroenterology2006,12,40:4

18Fractal analysis of retinal vasculature in normal subjects on ultra-wide field fluorescein angiography显示文摘AIM: To evaluate the fractal feature of the retinal vasculature of normal eyes on a stereographic projected and montaged ultra-wide field(UWF) fluorescein angiography(FA).METHODS: Prospective, observational, cross-sectional study. Totally 59 eyes of 31 normal subjects were imaged using the Optos 200 Tx. Images obtained at different gaze angles stereographically projected and montaged. The early-phase UWF FA frames were processed to segment the retinal vasculature and the results were exported as binary masks. The fractal dimension(FD) was calculated using the box-counting method.RESULTS: The global FD for the entire retina was 1.6±0.04, with no difference between males and females(1.59±0.04 vs 1.61±0.04, P=0.084) or between right and left eyes(1.6±0.04 vs 1.6±0.05, P=0.61). FD was nonuniformly distributed among four quadrants(P<0.001) and decreased as the distance from the fovea increased(P<0.001). A negative association was observed between FD and age(R=-0.37, P=0.006), and this relationship was observed in the posterior and mid-peripheral retina(P<0.05) but absent in far-periphery(P>0.05).CONCLUSION: Fractal geometry is non-uniformly distributed across the retina in normal eyes and decreases from the fovea to the far-periphery. Subjects with an older age tend to have a smaller FD, however, the FD in the farperiphery does not appear to be influenced by age.Wen-Ying Fan Alan Fleming Gavin Robertson Akihito Uji Jano van Hemert Michael Singer Min Sagong Michael Ip SriniVas R.Sadda 2020International Journal of Ophthalmology(English edition)2020,13,7:3
