Open Journal of Stomatology 2017年第3期7卷 169-179页

作者： Sachio Tamaoki Hiroyuki Ishikawa Kyoko Oka Masao Ozaki Akiko Abe shunsuke takata Shozaburo Hata Section of Orthodontics Department of Oral Growth & Development Division of Clinical Dentistry Fukuoka Dental College Fu-kuoka Japan Fukuoka Dental College Fukuoka Japan Section of Pediatric Dentistry Department of Oral Growth & Development Division of Clinical Dentistry Fukuoka Dental College Fukuoka Japan

Purpose: To establish a new coordinate system using the incisive canal and incisive foramen in cases confirmed to have root resorption in the maxillary incisor region by cone beam computed tomography (CBCT) to investigate the positions of the central and lateral incisor roots and erupting maxillary canine tooth crowns in the horizontal plane. Methods: Nine patients (two males;mean age: 10.5 years old) with suspected incisor root resorption due to erupting maxillary canines on panoramic X-ray images and in whom incisor root resorption was confirmed on CBCT images were evaluated. A control group of 12 patients with a supernumerary tooth on one side (three males;mean age: 8.6 years old) was also examined. X, Y, and Z-axes were defined, and the positions of the centers of the central incisor root (U1) and lateral incisor root (U2) and the canine cusp (U3) were examined, along with alveolar process width and length. Results: In the control group, U1, U2, and U3 were located within a certain range without overlap, while, in the incisor root resorption group, U3 overlapped with U1 and U2 and tended to deviate centrally. U2 tended to be located further posteriorly than U3. The anteroposterior diameter of the alveolar process was 1.2 mm shorter in the incisor root resorption group (p < 0.05). Conclusions: The risk of incisor root resorption accompanying canine eruption can be evaluated early by investigating the canine position on a horizontal plane established on the upper anterior tooth dentition CT images with a coordinate system using the incisive canal and incisive foramen.

Background Following on from an earlier study published in 2008 about left pulmonary artery(LPA)flow measured on serial echocardiography being strongly prognostic in left-sided congenital diaphragmatic hernia(CDH)and the ratio of LPA to right pulmonary artery(RPA)diameters being a simple and reliable indicator for commencing nitric oxide(NO)therapy,the ratio of LPA:RPA diameters(PA ratio orPAR)was hypothesized to possibly reflect cardiopulmonary stresses accompanying CDH *** Subjects with isolated left-sided CDH treated between 2007 and 2020 at a single pediatric surgical center were recruited and classified according to *** obtained retrospectively for subject demographics,clinical course,LPA/RPA diameters,and PAR were compared between survivors and *** value of PAR for optimizing the prognostic value of PA diameter data in CDH were analyzed with receiver operating characteristic(ROC)curve *** Of 65 subjects,there were 54 survivors(82.3%)and 11 non-survivors(17.7%);7 of 11 non-survivors died before surgical repair could be *** PAR for survivors(0.851±0.152)was significantly higher than for non-survivors(0.672±0.108)(p=0.0003).Mean PAR for non-survivors was not affected by surgical *** of survivors were:LPA≥2 mm(n=52 of 54;mean PAR=0.866±0.146)and RPA≥3mm(n=46 of 54;mean PAR=0.857±0.152).Non-survivors with similar LPA and RPA diameters to survivors had significantly lower mean *** curve cut-off for PAR was *** with high PAR(≥0.762)required high-frequency oscillatory ventilation/NO less than subjects with low PAR(<0.762)(p=0.0244 and p=0.0485,respectively)and subjects with high PAR stabilized significantly earlier than subjects with low PAR(1.71±0.68 days vs 3.20±0.87 days)(p<0.0001).Conclusions PAR would appear to be strongly correlated with clinical outcome in CDH and be useful for planning management of cardiopulmonary instability in CDH.

Clinicopathological characteristics of human epidermal growth factor receptor 2-positive Barrett's adenocarcinoma

作者： Takehiro Tanaka Atsushi Fujimura Koichi Ichimura Hiroyuki Yanai Yasuharu Sato Katsuyohi takata Hiroyuki Okada Seiji Kawano shunsuke Tanabe Tadashi Yoshino Department of Pathology Okayama University Hospital Okayama 700-8558 Japan Department of Physiology Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences Okayama 700-8558 Japan Department of Pathology Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences Okayama 700-8558 Japan Department of Endoscopy Okayama University Hospital Okayama 700-8558 Japan Department of Gastroenterological Surgery Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences Okayama 700-8558 Japan

AIM:To compare the clinicopathological characteristics of human epidermal growth factor receptor 2 (HER2)-positive and HER2-negative Barrett's adenocarcinoma in Japan. METHODS:We performed immunohistochemical analysis of HER2 in 30 samples taken from patients with Barrett's adenocarcinoma and dual color in situ hybridization in cases showing 2+ reactions. We compared the clinicopathological characteristics of HER2-positive and HER2-negative ***:HER2 positivity was identified in 8 (27%) carcinoma samples. We found that HER2 expression was associated with p53 overexpression (100% vs 52.6% in pT1 tumor; 100% vs 54.5% in all stage tumor, P < 0.05) and protruding lesions at the early disease stage. There was no association between the mucin phenotype of the carcinomas and prognosis. HER2 expression and low clinical stage were unexpectedly different between Barrett's adenocarcinoma patients and gastric cancer patients, but the macroscopic features may be associated with earlier diagnosis in these patients. CONCLUSION:Our results suggest that HER2-positive Barrett's adenocarcinomas are associated with p53 overexpression and lesion protrusion at the early disease stage.
