Acquiring clinical reasoning skills in lectures may be difficult, but it can learnt through problem-solving the context of practice. Problem finding and solving are required for reasoning; however, students who underwent problem-based learning (PBL) still have difficulty acquiring skills. We hypothesized that team-based (TBL), a strategy provides opportunity to solve problems by repeatedly taking tests, enhance ability medical with PBL experiences during pre-clinical years. TBL courses were...

Abstract Introduction We used data from MOBI-Kids, a 14-country international collaborative case–control study of brain tumors (BTs), to clinical characteristics the in older children (10 years or older), adolescents and young adults (up age 24). Methods Information records was obtained for 899 BT cases, including signs symptoms, symptom onset, diagnosis date, tumor type location. Results Overall, 64% all were low-grade, 76% neuroepithelial 62% gliomas. There more males than females among...
