Objective: The Pharmaceuticals and Medical Devices Agency (PMDA) discloses reports with accumulated side effect information in comma-separated value (CSV) format. It is difficult to use the information in this type of text file because the amount of data is large and composed of multiple fields. Therefore, we developed an application that presents the data in a way that is easier to read and understand.
Methods: The application can display the whole dataset, or the search results of certain medicines and side effects within the database in Microsoft Access 2013. It exports data from search results into an Excel spreadsheet organized by medicine and side effect.
Results: This application makes it possible to understand statistics contained in the side effect dataset, such as the number of cases, the medicines, and the side effects themselves. Moreover, the application allows the totaled search results for the medicines and the side effects to be graphed. It also makes it possible to understand the sex and age distribution of patients, as well as the days elapsed before developing a side effect.
Conclusions: Recently, the importance of information concerning the safety of medicine has increased. This system could facilitate the effective use of side effect information and the creation of medicine risk management plans in medical institutions.

BACKGROUND: The canonical Wnt/β-catenin signaling pathway is a fundamental regulatory system involved in various biological events. ICG-001 selectively blocks the interaction of β-catenin with its transcriptional co-activator cyclic AMP response element-binding protein (CBP). Recent studies have provided convincing evidence of the inhibitory effects of ICG-001 on Wnt-driven disease models, such as organ fibrosis, cancer, acute lymphoblastic leukemia, and asthma. However, the effects of ICG-001 in atopic dermatitis (AD) have not been investigated. OBJECTIVE: To investigate whether β-catenin/CBP-dependent signaling was contributed in the pathogenesis of AD and ICG-001 could be a therapeutic agent for AD. METHODS: We examined the effects of ICG-001 in an AD-like murine model generated by repeated topical application of the hapten, oxazolone (Ox). ICG-001 or vehicle alone was injected intraperitoneally every day during the development of AD-like dermatitis arising from once-daily Ox treatment. RESULTS: Ox-induced AD-like dermatitis characterized by increases in transepidermal water loss, epidermal thickness, dermal thickness accompanied by increased myofibroblast and mast cell counts, and serum levels of thymic stromal lymphopoietin and thymus and activation-regulated chemokine, and decreases in stratum corneum hydration, were virtually normalized by the treatment with ICG-001. Elevated serum levels of periostin tended to be downregulated, without statistical significance. CONCLUSION: These results suggest that β-catenin/CBP-dependent signaling might be involved in the pathogenesis of AD and could be a therapeutic target.
