OBJECTIVE: To evaluate the role of the tuberculin test in the diagnosis of tuberculosis in children. METHODS: Test diagnosis study; Tuberculin test with PPD Rt 23 (2 UT) was performed in 158 children, distributed in 2 groups: 101 no tuberculous, BCG vaccinated children and 57 tuberculous ones (diagnosis by clinical-radiological and epidemiological features). The interpretation of the tuberculin...

easily differentiated from the BY normal contour and color of the A. R. MASTEN, M.D. s]dn Specific because without wheatridge, Colo. a pl.ece(]jng infection with tubercle bacilli no reaction will occur. Accurate because no other known combination of factors will give the same result. That is, a person cannot become sensitive to tuberculin by any means except a previous infection with tubercle b...

OBJECTIVE The purpose of this study was to explore the association between tuberculin reaction size in contacts with positive tuberculin skin test results and a variety of contact and index patient variables. PATIENTS AND METHODS We reviewed the contact investigation records for tuberculosis patients identified by the Tuberculosis Prevention and Control Center of Lleida, Spain, over a period ...

Until some time ago, the tuberculin skin test was the only available screening test for the diagnosis of tubercular infection. Now the new interferon-? release assay QuantiFERON-TB Gold shows promise of greater accuracy in the detection of Mycobacterium tuberculosis-infected subjects. The aim of our study was to evaluate the use of QuantiFERONTB Gold in children and to verify its agreement with...

It is well known that after Bacille Calmette-Gue'rin (B.C.G.) vaccination the degree of allergy as shown by the tuberculin test is of a lesser order than that after infection with virulent tubercle bacilli. For this reason it may be necessary to perform several successively stronger tuberculin tests up to 100 units of old tuberculin (Mantoux 1/100) before a positive post-vaccination test is obt...

In the present study, T-Spot.TB and the tuberculin skin test (TST) were compared in the screening of latent tuberculosis infection among silicotic patients. A conditional probability model was used to compare the potential clinical utilities of T-Spot.TB and TST performed on 134 silicotic subjects from December 1, 2004 to January 31, 2007. Data from a historical cohort were also reanalysed for ...

The study was carried out in zoo animals at Islamabad Zoo, Pakistan to know the prevalence of bovinetuberculosis. An overall prevalence of 3.3% was recorded in zoo animals with 3.6% in Bovidae, 3.2% inCervidae and 0% in Equidae families. The positive animals included spotted deer (1/3; 95% CI = 0.84,90.57), Chinkara gazella (1/5; 95% CI = 0.51, 71.64) and Blackbuck gazelle (1/30; 95% CI = 0.08,...

The value of tuberculin skin testing in the diagnosis of active tuberculosis remains uncertain. Interpretation of tuberculin tests would be easier if the tuberculin test profiles in different communities were accurately known. We reviewed 468 Mantoux test reactions in patients coming to Hospital Universiti Sains Malaysia with suspected tuberculosis. Eighty six percent of patients with active tu...

In response to a difference in pricing, the San Diego Veterans Administration Medical Center changed its tuberculin preparation from Tubersol to Aplisol in the fall of 2006. Following the change, an increased number of employee skin test conversions was noted. Employee tuberculin skin test converters from 2006 were screened with the QuantiFERON Gold (QFT-G) gamma interferon release assay. Those...
