Cartoon versus traditional self-study handouts for medical students: CARTOON randomized controlled trial.

Objective: The objective of this study is to compare the effectiveness of a "cartoon-style" handout with a "traditional-style" handout in a self-study assignment for preclinical medical students.

Methods: Third-year medical students (n = 93) at the Faculty of Medicine Ramathibodi Hospital, Mahidol University, took a pre-learning assessment of their knowledge of intercostal chest drainage. They were then randomly allocated to receive either a "cartoon-style" or a "traditional-style" handout on the same topic.

Evaluation of real-time polymerase chain reaction for detection of the 16S ribosomal RNA gene of Mycobacterium tuberculosis and the diagnosis of cervical tuberculous lymphadenitis in a country with a high tuberculosis incidence.

Background: Tuberculous lymphadenitis (TBL) is the most common form of extrapulmonary tuberculosis. Currently, the standard diagnostic test for TBL is culture, which takes more than several weeks to yield results. We studied a real-time polymerase chain reaction (PCR) for rapid detection of Mycobacterium tuberculosis in cervical lymph node specimens obtained from patients in a country where the tuberculosis incidence is high.
