OBJECTIVE To describe developmental characteristics, morphological aspects and incidence of temporal sharp transients (TST) in normal preterm and term newborns at matched conceptional ages (CA). METHOD Neonatal EEGs from two groups of normal newborns were evaluated in order to identify and characterize TST. Group I (n=40) consisted of newborns from 34 to 40 weeks of gestational age (GA) that ...
BACKGROUND Reactivation of latent Mycobacterium tuberculosis infection (LTBI) is a health concern for patients on dialysis or receiving a kidney transplant, as these patients are often immunosuppressed. The most frequently used test for LTBI screening in this population is the tuberculin skin test (TST). The diagnostic accuracy (sensitivity and specificity) of the TST in a contemporary North Am...
BACKGROUND Immunologic tests such as the tuberculin skin test (TST) and QuantiFERON®-TB Gold In-Tube test (QFT-GIT) are designed to detect Mycobacterium tuberculosis infection, both latent M. tuberculosis infection (LTBI) and infection manifesting as active tuberculosis disease (TB). These tests need high specificity to minimize unnecessary treatment and high sensitivity to allow maximum detect...
OBJECTIVE In Fukujuji Hospital, we have been conducting TST to tuberculosis (TB) non-infected staffs to find new latent TB Infection (LTBI) every year, although almost of them were BCG vaccinated, and the reliability of TST is controversial in BCG vaccinated group. Recently, a new technique, QFT-2G, is evaluated highly to detect TB infection, especially in BCG vaccinated individuals. We examine...
BACKGROUND Bovine tuberculosis (TB) control programs generally rely on the tuberculin skin test (TST) for ante-mortem detection of Mycobacterium bovis-infected cattle. RESULTS Present findings demonstrate that a rapid antibody test based on Dual-Path Platform (DPP®) technology, when applied 1-3 weeks after TST, detected 9 of 11 and 34 of 52 TST non-reactive yet M. bovis-infected cattle from t...
This study accesses the development of Taedok Science Town(TST) with regards to its potential for regional development. After reviewing the potential of TST as engines of regional innovation, it analyzes the growth of R&D activities and spin-off’s from the field of high-tech venture business. The innovative activities of universities in TST are examined in detail and evaluated in relation to se...
BACKGROUND Reexamining the prevalence of persons infected with tuberculosis (TB) is important to determine trends over time. In 2011-2012 a TB component was included in the National Health and Nutrition Examination Survey (NHANES) to estimate the reservoir of persons infected with TB. METHODS Civilian, noninstitutionalized U.S. population survey participants aged 6 years and older were interv...
BACKGROUND BCG-vaccination can confound tuberculin skin test (TST) reactions in the diagnosis of latent tuberculosis infection. METHODS We compared the TST with a Mycobacterium tuberculosis specific whole blood interferon-gamma assay (QuantiFERON-TB-Gold In Tube; QFT-G) during ongoing investigations among close contacts of sputum smear positive source cases in Hamburg, Germany. RESULTS Duri...
BACKGROUND There are limited data comparing the performance of the two commercially available interferon gamma (IFN-gamma) release assays (IGRAs) for the diagnosis of tuberculosis (TB) in children. We compared QuantiFERON-TB gold In Tube (QFT-IT), T-SPOT.TB and the tuberculin skin test (TST) in children at risk for latent TB infection or TB disease. METHODS AND FINDINGS The results of both IG...
