This study aimed to assess the diagnostic accuracy of symptoms, signs and diagnostic tests in patients with rectal bleeding in relation to risk of colorectal cancer in primary care. METHODS Diagnostic accuracy systematic review. Medline (1966 to May 2009), Embase (1988 to May(More)
Until now, positive effects of assessment at a medical curriculum level have not been demonstrated. This study was performed to determine whether an interim assessment, taken during a small group work session of an ongoing biomedical course, results in students' increased performance at the formal course examination. A randomized controlled trial was set(More)
In a previous study we demonstrated by a prospective controlled design that an interim assessment during an ongoing small group work (SGW) session resulted in a higher score in the course examination. As this reflects the so-called testing effect, which is supposed to be enhanced by feedback, we investigated whether feedback following an interim assessment(More)
BACKGROUND Underutilization of dialogue among students during small-group work is a threat to active meaningful learning. To encourage small-group learning, we challenged students to generate written questions during a small-group work session. As gender differences have been shown to affect learning, these were also inventoried. METHODS Prospective(More)
Among patients with systemic lupus erythematosus (SLE) there is an increased risk of haematological malignancies, especially non-Hodgkin lymphoma. However, the association of SLE with aggressive CD3 negative natural killer (NK)-cell leukaemia has not been reported so far. We present a case of a 39-year-old woman with SLE, aggressive NK-cell leukaemia and(More)
BACKGROUND Misconceptions are ideas that are inconsistent with current scientific views. They are difficult to detect and refractory to change. Misconceptions can negatively influence how new concepts in science are learned, but are rarely measured in biomedical courses. Early identification of misconceptions is of critical relevance for effective teaching,(More)
