1)Palliative care education by means e–learning was performed from December 3 to 25, 2009, for 1256 hospital medical staff. We used the same true–or–false questions to assess their understanding before and after the e–learning course.
2)Regardless of the staff member’s experience, the total scores on the test were higher after the course than before the course. Therefore, this e–learning course had an effect on basic knowledge for multiple types of medical staff.
3)The percentage of correct answers was particularly improved for questions about topics we had emphasized: drug dependence and side effects.

STUDY DESIGN: Preliminary clinical trial. PURPOSE: To determine the safety and initial efficacy of intradiscal injection of autologous platelet-rich plasma (PRP) releasate in patients with discogenic low back pain. OVERVIEW OF LITERATURE: PRP, which is comprised of autologous growth factors and cytokines, has been widely used in the clinical setting for tissue regeneration and repair. PRP has been shown in vitro and in vivo to potentially stimulate intervertebral disc matrix metabolism. METHODS: Inclusion criteria for this study included chronic low back pain without leg pain for more than 3 months; one or more lumbar discs (L3/L4 to L5/S1) with evidence of degeneration, as indicated via magnetic resonance imaging (MRI); and at least one symptomatic disc, confirmed using standardized provocative discography. PRP releasate, isolated from clotted PRP, was injected into the center of the nucleus pulposus. Outcome measures included the use of a visual analog scale (VAS) and the Roland-Morris Disability Questionnaire (RDQ), as well as X-ray and MRI (T2-quantification). RESULTS: Data were analyzed from 14 patients (8 men and 6 women; mean age, 33.8 years). The average follow-up period was 10 months. Following treatment, no patient experienced adverse events or significant narrowing of disc height. The mean pain scores before treatment (VAS, 7.5±1.3; RDQ, 12.6±4.1) were significantly decreased at one month, and this was generally sustained throughout the observation period (6 months after treatment: VAS, 3.2±2.4, RDQ; 3.6±4.5 and 12 months: VAS, 2.9±2.8; RDQ, 2.8±3.9; p<0.01, respectively). The mean T2 values did not significantly change after treatment. CONCLUSIONS: We demonstrated that intradiscal injection of autologous PRP releasate in patients with low back pain was safe, with no adverse events observed during follow-up. Future randomized controlled clinical studies should be performed to systematically evaluate the effects of this therapy.

Objective: Prolonged use of Kampo medicines containing Gardenia fruit can cause mesenteric phlebosclerosis. A cumulative dose exceeding 5,000 g of Gardenia fruit may trigger this condition. However, the Japanese Pharmacopoeia 18th edition only specifies the minimum geniposide content in Gardenia fruits, making it difficult to assess the risk based solely on the cumulative Gardenia fruit dose. Hence, we evaluated mesenteric phlebosclerosis risk concerning cumulative geniposide intake in the current study. Quantitative analyses were conducted on ethical Kampo extract formulations containing Gardenia fruit. Methods: Ethical Kampo extract formulations containing Gardenia fruit were separately extracted using an H2O/methanol (1:1) solution and the resulting extracts underwent filtration. Each filtrate underwent quantitative, high-performance liquid chromatography analysis. Results: Significant variation was observed in the geniposide quantities among various ethical Kampo extract formulations containing identical amounts of Gardenia fruit in each daily dose. Additionally, the extracts of orengedokuto, kamishoyosan, and bofutsushosan obtained from various companies exhibited maximum differences in geniposide quantities ranging from 1.5- to 2.7-fold. Conclusion: This study highlights the challenges in accurately assessing geniposide levels in ethical Kampo extract formulations containing Gardenia fruit solely based on the daily dose of Gardenia fruit. The potential development of mesenteric phlebosclerosis should be considered based on the cumulative intake of geniposide rather than the cumulative dose of Gardenia fruit. Additionally, the study offers recommendations regarding the optimal geniposide quantities in ethical Kampo extract formulations containing Gardenia fruits.

BACKGROUND/AIMS: Tacrolimus is effective for refractory ulcerative colitis in adults, while data for children is sparse. We aimed to evaluate the effectiveness and safety of tacrolimus for induction and maintenance therapy in Japanese children with ulcerative colitis.METHODS: We retrospectively reviewed the multicenter survey data of 67 patients with ulcerative colitis aged < 17 years treated with tacrolimus between 2000 and 2012. Patients’ characteristics, disease activity, Pediatric Ulcerative Colitis Activity Index (PUCAI) score, initial oral tacrolimus dose, short-term (2-week) and long-term (1-year) outcomes, steroid-sparing effects, and adverse events were evaluated. Clinical remission was defined as a PUCAI score < 10; treatment response was defined as a PUCAI score reduction of ≥ 20 points compared with baseline.RESULTS: Patients included 35 boys and 32 girls (median [interquartile range] at admission: 13 [11–15] years). Thirty-nine patients were steroid-dependent and 26 were steroidrefractory; 20 had severe colitis and 43 had moderate colitis. The initial tacrolimus dose was 0.09 mg/kg/day (range, 0.05–0.12 mg/kg/day). The short-term clinical remission rate was 47.8%, and the clinical response rate was 37.3%. The mean prednisolone dose was reduced from 19.2 mg/day at tacrolimus initiation to 5.7 mg/day at week 8 (P< 0.001). The adverse event rate was 53.7%; 6 patients required discontinuation of tacrolimus therapy.CONCLUSIONS: Tacrolimus was a safe and effective second-line induction therapy for steroid-dependent and steroid-refractory ulcerative colitis in Japanese children.
