1Cerebral sinus thrombosis in patients with inflammatory bowel disease: A case report显示文摘Inflammatory bowel disease (IBD) is an idiopathic inflammatory disease of the gastrointestinal tract. The pathophysiology of IBD is probably the result of the complex interaction of genetic susceptibility and environmental influences. There is a well-known risk of thrombosis in patients with IBD. We present the case of a 53-year-old man with ulcerative colitis, who spontaneously developed intracranial sinus thrombosis that was treated with low molecular weight heparin. Literature was searched to assess the frequency and characteristics of cerebral sinus thrombosis in IBD and the role of certain etiopathological factors in such thrombotic patients.Hasan Umit Talip Asil Yahya Celik Ahmet Tezel Gulbin Dokmeci Nermin Tuncbilek Ufuk Utku Ali Riza Soylu 2005World Journal of Gastroenterology2005,11,34:6

4Adipokines and ghrelin in gastric cancer cachexia显示文摘AIM:To investigate the roles of the adipocytokines,ghrelin and leptin in gastric cancer cachexia. METHODS:Resistin,ghrelin,leptin,adiponectin,insulin and insulin-like growth factor(IGF-Ⅰ),were measured in 30 healthy subjects,and 60 gastric cancer patients of which 30 suffered from cancer-induced cachexia and 30 served as a control group. The relationships between hormones,body mass index(BMI) loss ratio,age,gender,and Glasgow Prognostic Score(GPS) were investigated. RESULTS:Cachexia patients had higher tumor stage and GPS when compared with non-cachexia patients(P < 0.05). Ghrelin,resistin,leptin,adiponectin and IGF-Ⅰ,showed a significant correlation with BMI loss ratio and GPS(P < 0.05). A strong correlation was seen between GPS and BMI loss(R = -0.570,P < 0.0001). Multivariate analysis indicated that BMI loss was significantly independent as a predictor of ghrelin,resistin,leptin and IGF-Ⅰ(P < 0.05). Existence of an important significant relationship between resistin and insulin resistance was also noted. CONCLUSION:These results showed that serum ghrelin,leptin,adiponectin,and IGF-Ⅰ play important roles in cachexia-related gastric cancers. No relationshipwas found between resistin and cancer cachexia. Also,because of the correlation between these parameters and GPS,these parameters might be used as a predictor factor.Mustafa Kerem Zafer Ferahkose Utku Tonguc Yilmaz Hatice Pasaoglu Ebru Ofluoglu Abdulkadir Bedirli Bulent Salman Tevfik Tolga Sahin Murat Akin 2008World Journal of Gastroenterology2008,14,23:4
5Treatment of chronic hepatitis B patients with tyrosinemethionine-aspartate-aspartate mutations显示文摘Lamivudine is an antiviral used for the treatment of chronic hepatitis B. Several studies have reported various mutations that are induced by lamivudine therapy. These mutations in the tyrosine-methionineaspartate-aspartate(YMDD) motif are necessary and sufficient to confer high-level lamivudine resistance. During treatment with lamivudine, mutations develop in the YMDD motif of the hepatitis B virus(HBV) polymerase gene and lamivudine cannot prevent the replication of the mutant form. The virulence strain of developed mutation in the polymerase gene is lower than the original virus and they are susceptible to treatment with some other nucleoside analogs except lamivudine. Entecavir and tenofovir are potent HBV inhibitors and they can be confidently used as first line monotherapies. We read the article written by Tan et al that lamivudine therapy improved the clinical course in HBV patients with natural YMDD mutations. We think that lamivudine use for this patient group is not appropriate. These patients should use YMDD mutant form-effective drugs such as adefovir, tenofovir.Aylin Calica Utku Oguz Karabay 2016World Journal of Gastroenterology2016,22,4:4

7Application of scoring systems with point-of-care ultrasonography for bedside diagnosis of appendicitis显示文摘BACKGROUND: Appendicitis is a common disease requiring surgery. Bedside ultrasound(BUS) is a core technique for emergency medicine(EM). The Alvarado score is a well-studied diagnostic tool for appendicitis. This study aimed to investigate the relationship between patients' symptoms, Alvarado score and ultrasound(US) findings, as performed by emergency physicians(EPs) and radiologists, of patients with suspected appendicitis.METHODS: Three EM specialists underwent the BUS course and core course for appendicitis assessment. Patients suspected of having appendicitis were selected and their Alvarado and modif ied(m) Alvarado scores calculated. The specialists performed the BUS. Then, patients were given a formal US and surgery consultation if necessary. Preliminary diagnoses, admission or discharge from the emergency department(ED) and fi nal diagnosis were documented. The patients were also followed up after discharge from the hospital.RESULTS: The determined cut-off value was 2 for Alvarado and 3 for m Alvarado scores. The sensitivities of the two scores were 100%. Each score was used to rule out appendicitis. The results of EP-performed BUS were as follows: accuracy 70%, sensitivity 0.733, specifi city 0.673, + LR 2.24, and – LR 0.40(95%CI). Radiologists were better than EPs at diagnosing appendicitis and radiologists and EPs were equally strong at ruling out appendicitis by US. When US was combined with Alvarado and m Alvarado scores, EP US+Alvarado/m Alvarado scores ≤3 and radiology US+Alvarado/m Alvarado scores ≤4 perfectly ruled out appendicitis.CONCLUSION: BUS performed by EPs is moderately useful in detecting appendicitis. Combined with scoring systems, BUS may be a perfect tool for ruling out decisions in EDs.Erden Erol Unluer Rifat Urnal Utku Eser Serkan Bilgin Mehmet Haciyanh Orhan Oyar Haldun Akoglu Arif Karagoz 2016World Journal of Emergency Medicine2016,7,2:2
8X-linked juvenile retinoschisis: phenotypic and genetic characterization显示文摘Juvenile X-linked retinoschisis(XLRS, MIM#312700) belongs to a group of the vitreoretinal dystrophies. We aimed to describe the phenotype-genotype correlation of three XLRS cases in juveniles with different novel mutations from the Lithuanian population. The patients demonstrated macular retinoschisis and typical cyst-like cavities on spectral-domain optical coherence tomography(SD-OCT) images. The mean central foveal thickness was 569.7 μm. Two patients presented with peripheral retinoschisis. Flash electroretinogram demonstrated a reduced b/a ratio(<1.0) in all patients. RS1(NM_000330.3) gene coding exons Sanger sequencing was performed. RS1 c.599 G>T(p.R200 L) mutation was detected in one case, showing to be pathogenic in silico analysis. c.(92_97) ins C(p.W33 fs) mutation was identified for another patient, indicating the variant is possibly damaging in silico analysis. The third case was identified with a pathogenic mutation c.422 C>G(p.R141 H), HGMD CM981753. These are the first cases of XLRS in the Lithuanian population confirmed by molecular genotyping. Presented patients had a different genotype but similar phenotypic traits.Rasa Strupaite Laima Ambrozaityte Loreta Cimbalistiene Rimvydas Asoklis Algirdas Utkus 2018International Journal of Ophthalmology(English edition)2018,11,11:2
9A Comparison Study of Moving Object Index Structures显示文摘The task of selecting the most appropriate method for indexing the data according to application requires a careful comparison study of indices of interests. In particular, we consider object movements by tracing their trajectories within a predefined road network. MV3DR-tree and 3DR-tree constitute our first group indexing the objects moving in free movement scenarios. Besides, Mapping and MON-tree are the second group indexing the locations of objects moving over a network of road. Those access methods mainly organize a group of R-tree in order to index the underlying road network and the object movements. Our goal in this study is to evaluate existing proposals under fair circumstances with respect to storage consumption and spatio-temporal query execution performance. In our comparisons, we discuss the structure's sensibility to query's spatial and/or temporal extent as well as the tradeoff arising between two groups in terms of reliability and disk access performance. We believe that revealing the vulnerabilities of the selected structures, especially Mapping and MON-tree motivates us to design more robust organizations.Utku Kalay Oya Kalipsiz 2009Journal of Computer Science & Technology2009,24,6:2
