RESUMO
The model core curriculum for pharmaceutical education specifies the specific behavioral objectives (SBOs) concerning adverse drug reactions, which aims to train pharmacy students to manage adverse drug reactions. Fukuoka University Hospital has developed a problem-based learning (PBL) program concerning adverse drug reactions as long-term practical training to collect adverse event information, identify adverse effects, and acquire management skills. Students' level of satisfaction with the program was high (approximately 90%), and the mean self-evaluation score for the SBOs concerning adverse reaction was 4.4 (5-grade scale), showing a high level of understanding. In addition, students' will of participation to the adverse drug reaction-reporting system was significantly improved after the PBL program, showing the usefulness of this program (p=0.02). However, the results of the PBL program revealed students' insufficient knowledge of adverse reactions and lack of reviewing skills, suggesting the need to improve the education system whereby students can learn adverse drug reactions in clinical settings.

Melanoma is commonly associated with multi-organ metastasis, and bone is a frequent metastatic site for melanoma. However, the mechanism responsible for such melanoma-induced bone metastasis is still poorly understood. In the present study, the intracardiac inoculation of leukemia inhibitory factor (LIF)-producing human melanoma-derived cells (SEKI) developed osteolytic bone destruction in male BALB/cA-nu/nu nude mice. To elucidate the role of LIF in melanoma-induced osteolysis, cells were prepared in which the expression of LIF was reduced using a siRNA technique from the parent SEKI cells. Osteoclastogenesis was induced in the co-culture of LIF and/or SEKI cells with osteoblastic stromal cells in vitro, whereas the LIF-reduced SEKI cells did not induce osteoclastogenesis. The intracardiac inoculation of LIF-reduced SEKI cells resulted in a significant reduction in the incidence and number of bone metastasis in comparison to those in the mice inoculated with the parent SEKI cells. The expression of LIF was found in seven of nine human melanoma-derived cell lines, suggesting that LIF expression is a universal event in melanoma. These findings suggest that a potential role for LIF in the melanoma-induced bone metastasis possibly through the stimulation of osteoclastogenesis. LIF might therefore be a potentially effective drug target in the treatment of bone metastasis in melanoma.
