Abstract Insufficient labeling information regarding the appropriate age for prescribing drugs to pediatric population is challenging. This study aimed analyze off‐label prescription of age‐related patients using claims data from South Korea and assess consistency approved in Korea, United States, Europe, Japan. In 2020, 1004 unique were prescribed Korea. We found that 641 (63.8%, p < 0.0001) related prescriptions use at least once, total number was 2,236,669 (62.2%, 0.0001)....
Objective:We wanted to assess the trends of CT examinations that were conducted in an adult emergency department (ED). Materials and Methods:We searched medical database identify patients (≥ 18 years) who had visited ED number during period from January 2001 December 2010.We also analyzed types scans performed terms body parts, they as follows; head CTs, facial bone neckl chest abdominal miscellaneous CTs.Further, CTs subdivided angiography others.Results: A total 113656 examined for 409439...
Colorectal cancer is a leading cause of morbidity and mortality worldwide. Knowledge colorectal tumor growth importance for basic understanding biology the clinical handling disease.To conduct retrospective evaluation pattern by multidetector computed tomography (MDCT).Pathologically proven adenocarcinomas colon rectum in 44 patients were examined MDCT on at least two separate occasions with an interval >1 month not receiving therapy. Maximal longitudinal diameters, wall thicknesses, volume...
Abstract Background Little information is available on the use of chest computed tomography (CT) to predict breast tumor size in cancer, despite fact that CT examinations are being increasingly used. The purpose this study was evaluate value for predicting using pathology measurements as reference standards. Methods Tumor sizes (defined greatest diameter) were retrospectively measured preoperative images 285 patients with surgically proven unifocal, invasive carcinoma. Greatest diameters...
Objectives The purpose of this study was to evaluate the interpretation criteria, such as size ratio, stain and elasticity score, assess diagnostic performance sonographic elastography by using an advanced breast tissue‐specific imaging preset compared with that conventional sonography for differentiation benign malignant masses. Methods Conventional were performed in 104 patients (age range, 17–76 years; mean age, 47.7 years) 110 lesions (67 43 malignant; size, 1.69 cm). data from criteria...
Background Reliable magnetic resonance imaging (MRI) diagnosis is important in cases of posterolateral corner (PLC) injury due to the limitations physical examination patients with multi-ligament injury. Purpose To document appearance PLC knee on three-dimensional (3D) isotropic MR images, and determine significance MRI findings confirmed rotatory instability. Material Methods Twenty-five that underwent surgery for instability, 25 individuals normal constituted study cohort. The appearances...
Objective:We wanted to assess the trends of computed tomography (CT) examinations in a pediatric emergency department (ED). Materials and Methods:We searched medical database identify patients who had visited ED, number CTs conducted from January 2001 December 2010.We analyzed types CTs, according anatomic region, underwent CT for multiple regions.Data were stratified, patient age (< 13 years ≤ ages < 18 years). Results:The performed per 1000 increased by 92% during 10-year period (per...
This study aimed to retrospectively evaluate the radiological features between rapid- and slow-growing renal cell carcinoma (RCC).Twenty-five pathologically proven RCCs were reviewed with computed tomography (CT). Each tumor underwent at least 2 CT sessions. Growth rate was evaluated in terms of its maximal diameter volume change serial scan. We 8 reports from single-institution series world literature regarding growth determined mean rate. Slow- rapid-growing compared relation several...
To evaluate morphologic variations at the aortic isthmus with particular attention to ductus diverticulum, a mimicker of traumatic pseudoaneurysm, and describe differences using Computed Tomography (CT) images.From December 2013 2014, patients who underwent chest CT examination after blunt trauma our emergency department were included. Aortic morphologies evaluated multiplanar reconstruction (MPR) maximum intensity projection (MIP) images as follows. Type I -concave contour, type II...
To evaluate sonographic findings in ischemic enterocolitis (IEC) and correlate with pathologic an experimental study.Ischemic was induced ligation of the superior mesenteric artery 20 rabbits. Plain radiography ultrasonography (US) were performed. US done hourly after using 10 MHz linear probe. categorized into 2 groups according to bowel wall echogenicity; echogenic dots (ED) group circumferential granular echogenicity (CGE) group. compared specimen histopathology.On US, ED seen all rabbits...
Abstract Background The Korean regulatory authority has enacted legislation to expedite the new drug approval (NDA) process. However, effectiveness of such efforts in reducing review time and delays between Korea USA/EU remains be evaluated. Methods We investigated NDA trends from 2011 2020 using information pharmaceutical companies. compared changes actual duration according active ingredient (chemical vs. biological), orphan status, therapeutic class, estimated submission gaps drugs US EU...
The aims of this study were to analyze cumulative effective dose (cED) and assess lifetime attributable risk (LAR) cancer due radiation exposure during computed tomography (CT) examinations in adolescent trauma patients.Between January 2010 May 2011, the patients with enrolled study. Numbers CT body regions examined collated, cEDs calculated using dose-length product values conversion factors. Lifetime for incidence cancer-associated mortality quantified based on studies survivors atomic...
Fibroadenomas are among the most common benign breast tumors in which carcinomas rarely develop. We report imaging findings of a microinvasive ductal carcinoma arising within fibroadenoma 51-year-old woman. This mass showed coarse heterogeneous microcalcifications circumscribed on mammography, hypoechoic ultrasound, and an early enhancing magnetic resonance imaging. Although older woman appears benign-looking, presence any unusual signs should raise concerns about malignancy.
본 연구는 장기간 주변 도시 조직과 단절되었던 용산 미8군 기지를 공원으로 조성함에 있어 도시와 상생할 수 있는 공원의 경계부 전략을 제안하고자 하였다. 정부 주도의 국가 도시공원으로 추진되고 용산공원을 대상으로 삼았으며 2012년 국제 설계 공모 이후 당선작에서 발전시킨 기본설계 및 공원조성계획안 중 출입 중심으로 살펴보았다. 약 11킬로미터에 달하는 공원 경계와 접한 도시의 물리적 특성과 성격을 분석하여 여덟 개의 유형으로 구분하고 각 유형에 적합한 경계부를 제안했다. 주요 보행로가 공원과 만나는 결절점에는 위계가 다양한 상징적, 기능적 나들문을 두었다. 또한 도시에 부족한 주민프로그램 공간이 마당의 형태로 제공되어 공원을 비물리적으로 연결하기도 한다. 계획안은 복잡성과 불확실성이 높은 대형 조성 과정에서, 변화해 나가는 서울시 도시계획 주변부 관리 계획과의 정합성 향상을 위해 성장과 재생을 견인하는 자기장으로써의 공원이라는 개념을 유지하되 확정적이기 보다 유연하고...
