To retrospectively investigate clinical and computed tomographic (CT) features of transient part-solid nodules (PSNs) initially detected at screening thin-section CT for lung cancer to determine predictive factors that may differentiate PSNs from persistent PSNs.This study was approved by the institutional review board. From January 2006 August 2008, 93 individuals with 126 were identified among 16777 who underwent chest CT. Clinical characteristics reviewed, compared between PSNs. identify...
PURPOSE: To retrospectively evaluate computed tomographic (CT) features of pleomorphic carcinoma the lung and to compare these with pathologic findings. MATERIALS AND METHODS: Ten patients (10 men, three women; mean age at diagnosis, 64.1 years; range, 43–75 years) treated from June 2000 January 2003 were selected two institutions. Two radiologists reviewed CT features, which included size location tumor, presence calcification, attenuation values internal architecture mass, invasion pleura...
Although the incidence of colorectal cancer is rising in Asian countries, there are no guidelines for its screening this region due part to lack epidemiological data regarding neoplasms. This study aimed evaluate prevalence neoplasms average-risk Koreans and assess effectiveness colonoscopy Korea.The was assessed by primary 5,086 consecutive asymptomatic adults (males 70.5%; age 20-84 years) with risk factors cancer.The overall subjects 21.9% increased linearly age. Among 2,435 aged >or=50...
PURPOSE: To examine the combined effects of monitor luminance and ambient light on observer performance for detecting abnormalities in a soft-copy interpretation digital chest radiographs. MATERIALS AND METHODS: A total 254 radiographs were displayed high-resolution cathode ray tube at three levels (25, 50, 100 foot-lamberts) under (0, 460 lux). Six radiologists reviewed each image nine modes light. The observers allowed to adjust window width level images. included nodule, pneumothorax,...
Objectives: To evaluate the efficacy of computer-aided detection (CAD) system and thin-slab maximum intensity projection (MIP) technique in pulmonary nodules at multidetector computed tomography (CT) patients who underwent metastatectomy. Materials Methods: This retrospective study was approved by institutional review board patients’ informed consent waived. Forty-nine consecutive metastatectomy were enrolled. Four chest radiologists analyzed preoperative 1-mm section CT images recorded...
To investigate the effect of saline chase injected at 2 different rates on computed tomography (CT) angiography.This study was approved by our institutional animal committee. Three injection protocols were used; contrast (24 mL, 0.8 mL/s) without (protocol A), with same rate as medium B), and half (0.4 C). In 3 dogs used in study, each applied twice for every dog resulting a total 18 sessions monitoring scans. CT images acquired second fixed level aorta pulmonary artery (PA). The duration...
Characteristic clinical features of melasma are symmetry hyperpigmentation and distribution related to trigeminal nerves, which suggest that the neural involvement could play a part in pathogenic mechanisms pigmentation.To evaluate whether some neuropeptides neurotrophins their receptors were associated with pathogenesis melasma.To investigate neuronal system melasma, we examined expression nerve growth factor receptor (NGFR) endopeptidase (NEP) lesional nonlesional skin. Skin biopsies...
To compare the computed tomography (CT) features of patients with multidrug-resistant tuberculosis those drug-sensitive in a country not associated human immunodeficiency virus (HIV) epidemic.The CT images 47 were compared as control group. Each patient was age (decade) and gender matched to patient. All seronegative HIV. This study evaluated presence centrilobular nodules, consolidation, emphysema, bronchiectasis, lung destruction, calcified granuloma, cavitation, pleural effusion,...
Objective: Uterine leiomyosarcoma (LMS) is a rare and aggressive disease with poor outcome.Due to its rarity conflict of data, investigation on finding prognostic factor challenging.The aim the study was investigate significance preoperative 18 F-fluorodeoxyglucose ( F-FDG) positron emission tomography/computed tomography (PET/CT) in uterine LMS.Methods: This retrospective observational cohort 3 tertiary referral hospitals.We retrospectively evaluated data from patients pathologically proven...
Objective: To evaluate the prognostic value of metabolic parameters measured by preoperative 18 F-fluorodeoxyglucose ( F-FDG) positron emission tomography (PET)/ computed (CT) in patients with uterine carcinosarcoma (UCS).Methods: Data 55 eligible UCS who underwent F-FDG PET/ CT and surgical staging were analyzed retrospectively.Maximum standardized uptake (SUV max ), tumor volume (MTV 2.5 total lesion glycolysis (TLG ) primary tumors using a SUV threshold 2.5.The optimal cutoff each...
Lymphoma is a rare malignancy of the breast, comprising approximately 0.04 to 0.5% breast malignancies. Because clinical findings lymphoma are nonspecific and similar those carcinoma, it important distinguish from other disease on basis radiologic findings. Elastography an interesting imaging tool that reflects tissue stiffness, increasingly being used in evaluation tumours. However, only limited number studies have focused elastographic lymphoma. In this report, we review characteristics...
UDP-glucose dehydrogenase (UGDH) catalyzes the synthesis of UDP-glucuronic acid from resulting in formation proteoglycans that are involved promoting normal cellular growth and migration. Overproduction has been implicated progression certain epithelial cancers. Here, human UGDH (hUGDH) was purified crystallized a solution 0.2 M ammonium sulfate, 0.1 Na cacodylate, pH 6.5, 21% PEG 8000. Diffraction data were collected to resolution 2.8 Å . The crystal belongs orthorhombic space group P212121...
A phyllodes tumor of the breast is a rare fibroepithelial tumor, accounting for 0.3% to 0.5% all tumors. The clinical presentation this unilateral, and behavior management are unclear. In addition, only few reports ectopic tumors currently available in literature. We report 29-year-old woman with palpable mass right axilla. She was diagnosed as having either fibroadenomatoid changes or benign according results core needle biopsy. Wide local excision performed 1 cm surgical border....
Convulsions with Noroviral Gastroenteritis in Children at a Single Center KoreaPurpose: Viral gastroenteritis is common disease infants and children.Seizures can be associated viral as benign convulsions mild (CwG).After the development of rotavirus vaccination, norovirus has become inreasingly significant children.We retrospectively analyzed clinical features pediatric population presenting seizures confirmed enteral infections, especially infections.Methods: We reviewed medical records...

Merkel cell carcinoma is a rare aggressive primary cutaneous neuroendocrine skin cancer arising from the basal epidermis.Although majority of patients with non-melanoma are cured by local treatment, have poor outcome characterized locoregional and distant relapse.No standard treatment protocol for exists.But, there mounting evidence that combined incorporating adjuvant radiotherapy, improves (locoregional control disease-free survival) compared surgery alone in most patients.Herein we report...
