| 1 | Preoperative evaluation of colorectal cancer using CT colonography, MRI, and PET/CT显示文摘Imaging studies are a major component in the evaluation of patients for the screening,staging and surveillance of colorectal cancer.This review presents commonly encountered findings in the diagnosis and staging of patients with colorectal cancer using computed tomography(CT)colonography,magnetic resonance imaging(MRI),and positron emission tomography(PET)/CT colonography.CT colonography provides important information for the preoperative assessment of T staging.Wall deformities are associated with muscular or subserosal invasion.Lymph node metastases from colorectal cancer often present with calcifications.CT is superior to detect calcified metastases.Three-dimensional CT to image the vascular anatomy facilitates laparoscopic surgery.T staging of rectal cancer by MRI is an established modality because MRI can diagnose rectal wall laminar structure.N staging in patients with colorectal cancer is still challenging using any imaging modality.MRI is more accurate than CT for the evaluation of liver metastases.PET/CT colonography isvaluable in the evaluation of extra-colonic and hepatic disease.PET/CT colonography is useful for obstructing colorectal cancers that cannot be traversed colonoscopically.PET/CT colonography is able to localize synchronous colon cancers proximal to the obstruction precisely.However,there is no definite evidence to support the routine clinical use of PET/CT colonography. | Shigeyoshi Kijima Takahiro Sasaki Koichi Nagata Kenichi Utano Alan T Lefor Hideharu Sugimoto | 2014 | World Journal of Gastroenterology2014,20,45: | 46 |
| 2 | Deep-learning classifier with ultrawide-field fundus ophthalmoscopy for detecting branch retinal vein occlusion显示文摘AIM: To investigate and compare the efficacy of two machine-learning technologies with deep-learning(DL) and support vector machine(SVM) for the detection of branch retinal vein occlusion(BRVO) using ultrawide-field fundus images. METHODS: This study included 237 images from 236 patients with BRVO with a mean±standard deviation of age 66.3±10.6 y and 229 images from 176 non-BRVO healthy subjects with a mean age of 64.9±9.4 y. Training was conducted using a deep convolutional neural network using ultrawide-field fundus images to construct the DL model. The sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV) and area under the curve(AUC) were calculated to compare the diagnostic abilities of the DL and SVM models. RESULTS: For the DL model, the sensitivity, specificity, PPV, NPV and AUC for diagnosing BRVO was 94.0%(95%CI: 93.8%-98.8%), 97.0%(95%CI: 89.7%-96.4%), 96.5%(95%CI: 94.3%-98.7%), 93.2%(95%CI: 90.5%-96.0%) and 0.976(95%CI: 0.960-0.993), respectively. In contrast, for the SVM model, these values were 80.5%(95%CI: 77.8%-87.9%), 84.3%(95%CI: 75.8%-86.1%), 83.5%(95%CI: 78.4%-88.6%), 75.2%(95%CI: 72.1%-78.3%) and 0.857(95%CI: 0.811-0.903), respectively. The DL model outperformed the SVM model in all the aforementioned parameters(P<0.001). CONCLUSION: These results indicate that the combination of the DL model and ultrawide-field fundus ophthalmoscopy may distinguish between healthy and BRVO eyes with a high level of accuracy. The proposed combination may be used for automatically diagnosing BRVO in patients residing in remote areas lacking access to an ophthalmic medical center. | Daisuke Nagasato Hitoshi Tabuchi Hideharu Ohsugi Hiroki Masumoto Hiroki Enno Naofumi Ishitobi Tomoaki Sonobe Masahiro Kameoka Masanori Niki Yoshinori Mitamura | 2019 | International Journal of Ophthalmology(English edition)2019,12,1: | 16 |
| 3 | Distribution of late gadolinium enhancement in various types of cardiomyopathies:Significance in differential diagnosis, clinical features and prognosis显示文摘The recent development of cardiac magnetic resonance(CMR)techniques has allowed detailed analyses of cardiac function and tissue characterization with high spatial resolution.We review characteristic CMR features in ischemic and non-ischemic cardiomyopathies(ICM and NICM),especially in terms of the location and distribution of late gadolinium enhancement(LGE).CMR in ICM shows segmental wall motion abnormalities or wall thinning in a particular coronary arterial territory,and the subendocardial or transmural LGE.LGE in NICM generally does not correspond to any particular coronary artery distribution and is located mostly in the mid-wall to subepicardial layer.The analysis of LGE distribution is valuable to differentiate NICM with diffusely impaired systolic function,including dilated cardiomyopathy,end-stage hypertrophic cardiomyopathy(HCM),cardiac sarcoidosis,and myocarditis,and those with diffuse left ventricular(LV)hypertrophy including HCM,cardiac amyloidosis and Anderson-Fabry disease.A transient low signal intensity LGE in regions of severe LV dysfunction is a particular feature of stress cardiomyopathy.In arrhythmogenic right ventricular cardiomyopathy/dysplasia,an enhancement of right ventricular(RV)wall with functional and morphological changes of RV becomes apparent.Finally,the analyses of LGE distribution have potentials to predict cardiac outcomes and response to treatments. | Hiroshi Satoh Makoto Sano Kenichiro Suwa Takeji Saitoh Mamoru Nobuhara Masao Saotome Tsuyoshi Urushida Hideki Katoh Hideharu Hayashi | 2014 | World Journal of Cardiology2014,6,7: | 8 |
| 4 | Transnasal endoscopic retrograde chalangiopancreatography using an ultrathin endoscope: A prospective comparison with a routine oral procedure显示文摘AIM: To investigate if transnasal endoscopic retrograde cholangiopancreatography (n-ERCP) using an ultrathin forward-viewing scope may overcome the disadvantages of conventional oral ERCP (o-ERCP) related to the large- caliber side-viewing duodenoscope. METHODS: The study involved 50 patients in whom 25 cases each were assigned to the o-ERCP and n-ERCP groups. We compared the requirements of esophagogastroduodenoscopy (EGD) prior to ERCP, rates and times required for successful cannulation into the pancreatobiliary ducts, incidence of post-procedure hyperamylasemia, cardiovascular parameters during the procedure, the dose of a sedative drug, and successful rates of endoscopic naso-biliary drainage (ENBD). RESULTS: Screening gastrointestinal observations were easily performed by the forward-viewing scope and thus no prior EGD was required in the n-ERCP group. There was no significant difference in the rates or times for cannulation, or incidence of hyperamylasemia between the groups. However, the cannulation was relatively difficult in n-ERCP when the scope appeared U-shape under fluoroscopy. Increments of blood pressure and the amount of a sedative drug were significantly lower in the n-ERCP group. ENBD was successfully performed succeeding to the n-ERCP in which mouth-to-nose transfer of the drainage tube was not required. CONCLUSION: n-ERCP is likely a well-tolerable methodwith less cardiovascular stress and no need of prior EGD or mouth-to-nose transfer of the ENBD tube. However, a deliberate application is needed since its performance is difficult in some cases and is not feasible for some endoscopic treatments such as stenting. | Akihiro Mori Noritsugu Ohashi Takako Maruyama Hideharu Tatebe Katsuhisa Sakai Takashi Shibuya Hiroshi Inoue Shoudou Takegoshi Masataka Okuno | 2008 | World Journal of Gastroenterology2008,14,10: | 6 |

| 6 | Laterally spreading tumors:Limitations of computed tomography colonography显示文摘AIM:To prospectively investigate the detection rate of laterally spreading tumors(LSTs)of the colorectum by computed tomography(CT)colonography(CTC).METHODS:Patients with LSTs measuring≥20 mm detected during colonoscopy were prospectively enrolled in the study.All patients underwent colonoscopy and subsequent CTC on the same day.CTC was performed using multi-detector CT without contrast in the prone and supine positions.Two radiologists blinded to the existence of LSTs read the virtual endoscopic images as well as 2-D images.LSTs were classified into granular and non-granular types based on colonoscopic appearance.RESULTS:Forty-seven pathologically proven LSTs were evaluated prospectively.Histology included adenomas in 19,mucosal cancers in 19 and T1 cancers in 9.The mean diameter of the LSTs was 35.1 mm.Twenty-eight(60%)LSTs were correctly identified by CTC,and the configuration was similar to the colonoscopic appearance in most cases.Detection rate for the granular type was significantly higher than that for the nongranular type(71%vs 31%,P=0.013).Detection rate of adenomas was significantly lower than mucosal cancers(32%vs 79%,P=0.008)and T1 cancers(32%vs 78%,P=0.042).CONCLUSION:The detection rate of LSTs by CTC,particularly the non-granular type was not acceptable.Practitioners should be aware of the relatively low detection rate when using CTC. | Kazutomo Togashi Kenichi Utano Shigeyoshi Kijima Yosuke Sato Hisanaga Horie Keijirou Sunada Alan T Lefor Hideharu Sugimoto Yoshikazu Yasuda | 2014 | World Journal of Gastroenterology2014,20,46: | 4 |
| 7 | Clinical and molecular characteristics of East Asian patients with von Hippel–Lindau syndrome显示文摘Background: Von Hippel–Lindau(VHL) syndrome is a dominantly inherited multisystem cancer syndrome caused by a heterozygous mutation in the VHL tumor suppressor gene. Previous studies suggested that similar populations of Caucasian and Japanese patients have similar genotype or phenotype characteristics. In this comprehensive study of East Asian patients, we investigated the genetic and clinical characteristics of patients with VHL syndrome.Methods: To create a registry of clinical characteristics and mutations reported in East Asian patients with VHL syndrome, we conducted a comprehensive review of English language and non?English language articles identi?fied through a literature search. Publications in Japanese or Chinese language were read by native speakers of the language, who then performed the data extraction.Results: Of 237 East Asian patients with VHL syndrome, 154 unique kindreds were identified for analysis. Analyzed by kindred, missense mutations were the most common(40.9%, 63/154), followed by large/complete deletions(32.5%, 50/154) and nonsense mutations(11.7%, 18/154). Compared with a previously reported study of both East Asian and non?East Asian patients, we found several key differences. First, missense and frameshift mutations in the VHL gene occurred less commonly in our population of East Asian patients(40.9% vs. 52.0%; P = 0.012 and 8.4% vs. 13.0%; P < 0.001, respectively). Second, large/complete deletions were more common in our population of East Asian patients(32.5% vs. 10.5%; P < 0.001). Third, phenotypically, we observed that, in our population of East Asian patients with VHL syndrome, the incidence of retinal capillary hemangioblastoma was lower, whereas the incidence of renal cell carcinoma was higher.Conclusions: Evidence suggests that the genotypic and phenotypic characteristics of East Asian patients with VHL syndrome differ from other populations. This should be considered when making screening recommendations for VHL syndrome in Asia. | Meihua Wong Ying-Hsia Chu Hwei Ling Tan Hideharu Bessho Joanne Ngeow Tiffany Tang Min-Han Tan | 2016 | Chinese Journal of Cancer2016,35,9: | 3 |
| 8 | Long-lasting responses after discontinuation of nivolumab treatment for reasons other than tumor progression in patients with previously treated,advanced non-small cell lung cancer显示文摘Dear Editor,Nivolumab,an inhibitor of programmed cell death 1(PD-1),is an immune checkpoint inhibitor(ICI)that enhances T cell functions by preventing negative regulation of cancer immunity,and it has shown clinically significant efficacy and tolerability in various types of cancer.Based on the results of randomized phase III trials comparing nivolumab with docetaxel[1,2],nivolumab is now used in clinical practice for patients with previously treated advanced non-small cell lung cancer(NSCLC).Fur-thermore,the most recent Japan Lung Cancer Society guidelines include nivolumab monotherapy in the sys-temic treatment strategy for previously treated,locally advanced or metastatic NSCLC[3].However,ICIs induce characteristic immune-related adverse events(irAEs),which are not seen with conventional cytotoxic agents or molecular targeted agents.IrAEs can occur in any organ system,most typically the skin,lung,and gastrointesti-nal,hepatic,and endocrine systems. | Hideharu Kimura Tomoyuki Araya Taro Yoneda Hiroki Shirasaki Koji Kurokawa Tamami Sakai Hayato Koba Yuichi Tambo Shingo Nishikawa Takashi Sone Kazuo Kasahara | 2019 | Cancer Communications2019,39,1: | 3 |

| 11 | Randomized study of lafutidine vs lansoprazole in patients with mild gastroesophageal reflux disease显示文摘AIM: To compare the clinical efficacy of the secondgeneration H2 RA lafutidine with that of lansoprazole in Japanese patients with mild gastroesophageal reflux disease(GERD). METHODS: Patients with symptoms of GERD and a diagnosis of grade A reflux esophagitis(according to the Los Angeles classification) were randomized to receive lafutidine(10 mg, twice daily) or lansoprazole(30 mg, once daily) for an initial 8 wk, followed by maintenance treatment comprising half-doses of the assigned drug for 24 wk. The primary endpoint was the frequency and severity of heartburn during initial and maintenance treatment. The secondary endpoints were the sum score of questions 2 and 3 in the Gastrointestinal Symptom Rating Scale(GSRS), and the satisfaction score.RESULTS: Between April 2012 and March 2013, a total of 53 patients were enrolled, of whom 24 and 29 received lafutidine and lansoprazole, respectively. After 8 wk, the frequency and severity of heartburn was significantly reduced in both groups. However, lafutidine was significantly inferior to lansoprazole with regard to the severity of heartburn during initial and maintenance treatment(P = 0.016). The sum score of questions 2 and 3 in the GSRS, and satisfaction scores were also significantly worse in the lafutidine group than the lansoprazole group(P = 0.0068 and P = 0.0048, respectively).CONCLUSION: The clinical efficacy of lafutidine was inferior to that of lansoprazole, even in Japanese patients with mild GERD. | Ryuta Takenaka Hiroyuki Okada Seiji Kawano Yoshinori Komazawa Fumiya Yoshinaga Shinji Nagata Masafumi Inoue Hirohisa Komatsu Seiji Onogawa Yoshinori Kushiyama Shinichi Mukai Hiroko Todo Hideharu Okanobu Noriaki Manabe Shinji Tanaka Ken Haruma Yoshikazu Kinoshita | 2016 | World Journal of Gastroenterology2016,22,23: | 2 |

| 15 | Microstructural evolution and mechanical properties of a low-carbon quenching and partitioning steel after partial and full austenitization显示文摘In this work, low-carbon steel specimens were subjected to the quenching and partitioning process after being partially or fully austenitized to investigate their microstructural evolution and mechanical properties. According to the results of scanning electron microscopy and transmission electron microscopy observations, X-ray diffraction analysis, and tensile tests, upper bainite or tempered martensite appears successively in the microstructure with increasing austenitization temperature or increasing partitioning time. In the partially austenitized specimens, the retained austenite grains are carbon-enriched twice during the heat treatment, which can significantly stabilize the phases at room temperature. Furthermore, after partial austenitization, the specimen exhibits excellent elongation, with a maximum elongation of 37.1%. By contrast, after full austenitization, the specimens exhibit good ultimate tensile strength and high yield strength. In the case of a specimen with a yield strength of 969 MPa, the maximum value of the ultimate tensile strength reaches 1222 MPa. During the partitioning process, carbon partitioning and carbon homogenization within austenite affect interface migration. In addition, the volume fraction and grain size of retained austenite observed in the final microstructure will also be affected. | Wan-song Li Hong-ye Gao Hideharu Nakashima Satoshi Hata Wen-huai Tian | 2016 | International Journal of Minerals,Metallurgy and Materials2016,23,8: | 2 |
| 16 | Intra-cardiac distribution of late gadolinium enhancement in cardiac sarcoidosis and dilated cardiomyopathy显示文摘Cardiac involvement of sarcoid lesions is diagnosed by myocardial biopsy which is frequently false-negative,and patients with cardiac sarcoidosis(CS) who have impaired left ventricular(LV) systolic function are sometimes diagnosed with dilated cardiomyopathy(DCM).Late gadolinium enhancement(LE) in magnetic resonance imaging is now a critical finding in diagnosing CS,and the novel Japanese guideline considers myocardial LE to be a major criterion of CS.This article describes the value of LE in patients with CS who have impaired LV systolic function,particularly the diagnostic and clinical significance of LE distribution in comparison with DCM.LE existed at all LV segments and myocardial layers in patients with CS,whereas it was localized predominantly in the midwall of basal to mid septum in those with DCM.Transmural(nodular),circumferential,and subepicardial and subendocardial LE distribution were highly specific in patients with CS,whereas the prevalence of striated midwall LE were high both in patients with CS and with DCM.Since sarcoidosis patients with LE have higher incidences of heart failure symptoms,ventricular tachyarrhythmia and sudden cardiac death,the analyses of extent and distribution of LE are crucial in early diagnosis and therapeutic approach for patients with CS. | Makoto Sano Hiroshi Satoh Kenichiro Suwa Masao Saotome Tsuyoshi Urushida Hideki Katoh Hideharu Hayashi Takeji Saitoh | 2016 | World Journal of Cardiology2016,8,9: | 2 |
