PURPOSE: To determine serial changes in hepatocellular carcinomas (HCCs) treated with percutaneous radio-frequency (RF) ablation at long-term follow-up multiphase helical computed tomography (CT). MATERIALS AND METHODS: There were 43 nodular HCCs 40 patients CT performed not less than 12 months after RF ablation. All underwent immediately, 1 month, and then every 3 The attenuation, enhancement pattern, shape, other findings, volume of the ablated lesions analyzed CT. RESULTS: Thirty-eight...
PURPOSE: To compare ferumoxides-enhanced magnetic resonance (MR) imaging with triple-phase helical computed tomography (CT) for the preoperative depiction of hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Seventy consecutive patients a total 79 HCC nodules underwent MR and CT before surgery. The diagnosis was established by means pathologic examination after surgical resection in all patients. images obtained sequences were reviewed independently three radiologists on...
OBJECTIVE. The purpose of this study was to evaluate the doubling time, frequency, and features on dynamic CT extrahepatic needle tract implantation malignant neoplasms after sonographically guided percutaneous biopsy for hepatocellular carcinoma (HCC).
Purpose Mutation-specific antibodies have recently been developed for identification of epidermal growth factor receptor (EGFR) mutations by immunohistochemistry (IHC). This study was designed to investigate whether the type specimen (biopsy vs. resection) would make a difference in determining mutation status IHC, and evaluate biopsies are suitable detection mutant EGFR protein. Materials Methods IHC performed using mutation-specific E746-A750 deletion (DEL) L858R point (L858R) tissue...
It is unclear whether the presence of minimal lung function impairment an independent risk factor for development cancer in general populations.We conducted a population-based cohort study using nationally representative data from Korean National Health and Nutrition Examination Survey Insurance Service.Of 20,553 participants, 169 were diagnosed with during follow-up (median, 6.5 years). Participants obstructive had increased (aHR: 2.51; 95% CI: 1.729-3.629) compared those normal function....

An emergence of drug-resistant tuberculosis (DR-TB) in settings affected by human immunodeficiency virus (HIV) and (TB) has been observed. We investigated the prevalence DR-TB P1041, a multicentered, randomised, double-blind trial which compared administration isoniazid (INH) to placebo, HIV-exposed, non-infected -infected African infants absence any documented TB exposure. The multidrug-resistant (MDR-TB) was 22.2% (95%CI 8.5-45.8) INH monoresistance 5.6% 0.1-27.6) among culture-confirmed...
Abstract Background: The purpose of the present study was to define differential diagnostic markers benign and malignant bile duct strictures without demonstrable mass on ultrasonography (US) or computed tomography (CT) using aspects clinical, laboratory imaging findings. Methods: Between February 1995 2001, 24 patients who underwent surgical resection for dilations (peripheral hilar) visible lesion US CT were included in our study. Hospital records, results, findings studies pathological...
Although influenza A (H1N1) virus leads to self-limiting illness, co-infection with bacteria may result in cases of severe respiratory failure due inflammation and necrosis intra-airway, as pseudomembranous tracheobronchitis. Pseudomembranous tracheobronchitis is usually developed immunocompromised patients, but it can also occur immunocompetent patients on a very rare basis. We report case complicated by inflenaza Staphylococcus aureus, causing acute patients.
To assess the value of computer-aided tissue echo quantification in differentiating small hyperechoic renal cell carcinomas from angiomyolipomas, we studied ultrasonographic images 15 and 20 angiomyolipomas. After digitizing images, measured absolute gray scale values cortex, central complex, mass. The relative (%) mass was calculated by setting cortex as 0% complex 100%. range 12 to 73% (mean, 28%), whereas that angiomyolipomas 30 204% 130%). differentiation between can be facilitated...
Abstract Oxidative stress plays important roles in inflammatory responses during acute lung injury (ALI). Recently, nanoconstruct (Nano)-based drug-delivery systems have shown promise many models of inflammation. In this study, we evaluated the anti-inflammatory effects N-acetylcysteine (NAC) loaded a biocompatible Nano using rat model ALI. We synthesized with good NAC-releasing capacity porous silica Nano, which was used to produce Nano/NAC complexes. For vivo experiments, Sprague–Dawley...
The purpose of our study was to assess whether a review multiphasic helical CT combined with the previous serial images could be helpful depict viable tumor in hepatocellular carcinoma treated transarterial chemoembolization.Twenty-four consecutive patients 35 carcinomas underwent chemoembolization followed by hepatic resection. First, three radiologists independently analyzed last taken before resection for presence tumor. A second analysis then performed using images. analyses were...
Standardized clinical case definitions represent the best option for pediatric tuberculosis (TB) disease diagnosis and classification.
International Maternal Pediatric Adolescent AIDS Clinical Trials (IMPAACT) P1041, a tuberculosis (TB) prevention trial conducted among children enrolled from 2004 to 2008 during South Africa's roll-out of combination antiretroviral therapy (ART).To estimate TB incidence and mortality the effect ART.Children were pre-screened exclude disease exposure, actively screened 3-monthly for exposure symptoms, provided post-exposure isoniazid prophylaxis (IPT). diagnoses definite, probable, or...
Bronchiectasis has long been neglected, unlike chronic obstructive pulmonary disease (COPD) and asthma. Recent clinical trials have shown that long-term use of azithromycin or erythromycin reduce exacerbations non-cystic fibrosis (non-CF) bronchiectasis. Because this, we should actively try to treat patients susceptible severe status.We enrolled who had diagnosed with bronchiectasis at five branches the Catholic Medical Center between January 2015 December 2017. We retrospectively analyzed...
Direct hemoperfusion with polymyxin B-immobilized fiber column in a patient acute exacerbation of idiopathic pulmonary fibrosisIdiopathic fibrosis (IPF) is progressive fibrosing interstitial lung disease characterized by dyspnea and worsening the function.Acute exacerbations (AE-IPF) are defined clinically significant respiratory deterioration, that typically develops less than 1 month, accompanied new radiologic abnormalities on high-resolution computed tomography, including diffused...
Isoniazid-monoresistant tuberculosis (Hr-TB) has emerged as a global challenge, necessitating detailed guidelines for its diagnosis and treatment. We aim to consolidate the Korean Hr-TB management by gathering expert opinions reaching consensus.A conventional Delphi method involving two rounds of surveys was conducted with 96 experts selected based on their clinical research experience involvement in nationwide studies development tuberculosis. The survey consisted three sections...
<b>Introduction:</b> The clinical outcome of acute respiratory failure (ARF) treated with high flow nasal cannula (HFNC) may be favorable, but sometimes ARF deteriorates and requires invasive mechanical ventilation (IMV). However, little is known about the factors affecting this difference. <b>Objective:</b> aim study to investigate predicting for HFNC in patients HFNC. <b>Methods:</b> A cohort consecutive was studied. defined as requiring IMV or death following <b>Results:</b> 212 were...
<b>Backgrounds:</b> Although left ventricular diastolic dysfunction (LVDD) is a frequent condition in COPD, there little study about this. <b>Methods:</b> A cohort of consecutive COPD outpatients who underwent echocardiography were reviewed. Patients with cardiovascular disease, cor pulmonale, or any disease need to take diuretics except LVDD excluded. The remaining patients divided into two groups based on prescription over 1 year: suspecting group (patients receiving diuretics) and...
