A priori quality assurance using a benchmark case of the randomized phase 2 GORTEC 2014-14 in oligometastatic head and neck cancer patients.

Purpose: A Benchmark Case (BC) was performed as part of the quality assurance process of the randomized phase 2 GORTEC 2014-14 OMET study, testing the possibility of multisite stereotactic radiation therapy (SBRT) alone in oligometastatic head and neck squamous cell carcinoma (HNSCC) as an alternative to systemic treatment and SBRT.

Material And Methods: Compliance of the investigating centers with the prescription, delineation, planning and evaluation recommendations available in the research protocol was assessed. In addition, classical dosimetric analysis was supplemented by quantitative geometric analysis using conformation indices.

[Screening contacts for latent tuberculosis infection (LTBI) using an interferon test in Paris in 2009].

There are two reasons for screening contacts: one is to identify cases of secondary tuberculosis disease (TB) and the other is to identify new cases of latent tuberculosis infection (LTBI). The tuberculin skin test (TST) and the interferon-gamma-release assay (IGRA) have their limitations when used for the detection of LTBI. They neither allow a definite diagnosis of LTBI nor provide information as to the date of onset.

[Student's use of illicit drugs: a survey in a preventive health service].

Aim Of The Study: To carry out a quantitative and qualitative epidemiological investigation of substance use within a student population seen during their mandatory preventive health visit at the University medical facility.
