Abstract
BACKGROUND AND AIMS Data from an all-cases post-marketing study were used to evaluate the safety and effectiveness of adalimumab in Japanese patients with Crohn's disease [CD]. METHODS Patients received adalimumab for 24 weeks. Data from all patients [n = 1693] were used for the safety assessment. Data from patients with CD activity index [CDAI] ≥ 150 at baseline were used for the effectiveness assessment. RESULTS The most frequent serious adverse drug reaction [ADR] was infection and infestations [6.6 events/100 patient-years]. The risk of serious infections increased in patients who had a history of malignancy and those with concomitant corticosteroid use. Of 415 patients who had switched from another anti-tumour necrosis factor alpha [TNFα] agent to adalimumab due to ADRs, 7.2% discontinued due to ADRs to adalimumab. Ten of 13 patients with a history of tuberculosis [TB] received prophylactic medication, and none developed TB. TB developed in one patient with no history of TB or anti-TB prophylaxis. Remission rates were 41.3% and 32.4% at 4 and 24 weeks, respectively. Remission rates did not differ between patients with and without concomitant use of immunomodulators. Predictive variables for increased effectiveness were CDAI ≤ 220 and disease duration of ≤ 2 years. Perianal lesions and loss of response to previous anti-TNFα agents affected effectiveness. CONCLUSIONS The most frequent serious ADR was infection. Adalimumab significantly reduced disease activity, without any unexpected ADRs. Development of active TB during adalimumab therapy can be prevented through TB screening and prophylaxis. In patients who switched from another anti-TNFα agent to adalimumab due to ADRs, adalimumab was well tolerated.

Abstract
The safety and efficacy of adalimumab were evaluated over 24 weeks in Japanese patients with psoriasis in routine clinical practice. In this multicenter, observational, open‐label, postmarketing study, primary efficacy measures included the Psoriasis Area and Severity Index (PASI) and the Dermatology Life Quality Index (DLQI) in all patients with psoriasis. In patients with psoriatic arthritis (PsA), the 28‐joint Disease Activity Score (DAS28) and the visual analog scale (VAS) pain were also evaluated. Safety was assessed based on the frequency of adverse drug reactions (ADR). Among patients with psoriasis evaluated for efficacy (n = 604), significant improvements from baseline were observed in mean PASI and DLQI scores at weeks 16 and 24 (all P < 0.0001). Furthermore, in psoriasis patients without PsA, the PASI 75/90 response rates were 55.9%/28.4% at week 16 (n = 306) and 65.6%/43.3% at week 24 (n = 270), respectively. In patients with PsA evaluable for effectiveness, significant improvements from baseline were observed in PASI, DAS28 erythrocyte sedimentation rate, DAS28 C‐reactive protein and VAS pain at weeks 16 and 24 (all P < 0.0001). ADR and serious ADR were reported by 26.1% and 3.3%, respectively, of 731 safety evaluable patients with psoriasis; no unexpected safety findings were noted. The safety profile and effectiveness of adalimumab for the treatment of psoriasis in a routine clinical setting were as expected in Japanese patients.

Abstract
While adjuvant chemotherapy is preferable for colon cancer, treatment duration is controversial. This phase III trial is investigated optimal duration of adjuvant chemotherapy for Stage IIB/III colon cancer. Eighteen-month treatment with UFT/LV did not improve DFS compared with 6-month UFT/LV treatment. This study suggests that 6 months treatment duration is enough for Stage IIB/III colon cancer. Background While adjuvant chemotherapy is preferable for high-risk colon cancer, treatment duration is controversial. Oral uracil and tegafur (UFT)/leucovorin (LV) is widely used as a standard adjuvant chemotherapy for colon cancer in Japan. We conducted a phase III trial to investigate the optimal duration of adjuvant chemotherapy for stage IIB/III colon cancer. Patients and methods Patients with curatively resected stage IIB/III colon cancer were eligible for enrollment in this trial. Patients were registered within 6 weeks after surgery and were randomly assigned to receive UFT/LV for 28 of 35 days for 6 months in the control group or for 5 consecutive days per week for 18 months in the study group. The primary end point was the disease-free survival (DFS), and the secondary end points were overall survival (OS) and safety. Result A total of 1071 patients were registered from 233 centers. A statistically significant difference in DFS was not observed between the study group and the control group; the 5-year DFS was 69% in the study group and 69% in the control group. The 5-year OS was 85% in the study group and 85% in the control group. Conclusion Eighteen-month treatment with UFT/LV did not improve DFS or OS compared with 6-month UFT/LV treatment in patients with stage IIB/III colon cancer. The important finding from this study is that not 18 months but 6 months of treatment is enough for postoperative UFT/LV for stage IIB/III colon cancer. Clinical trial number UMIN-CTR C000000245.

Abstract
Magnesium oxide has been experimentally and computationally investigated in the warm-dense solid and liquid ranges from 200 GPa to 1 TPa along the principal Hugoniot. The linear approximation between shock velocity and particle velocity is validated up to a shock velocity of 15 km/s from the experimental data, this suggesting that the MgO B1 structure is stable up to the corresponding shock pressure of ∼350 GPa. Moreover, our Hugoniot data, combined with ab initio simulations, show two crossovers between MgO Hugoniot and the extrapolation of the linear approximation line, occurring at a shock pressures of approximately 350 and 650 GPa, with shock temperatures of 8000 and 14,000 K, respectively. These crossover regions are consistent with the solid-solid (B1-B2) and the solid-liquid (B2-melt) phase boundaries predicted by the ab initio calculations.

Abstract
Dipyridamole was used in 30 cases of nephrotic syndrome, mostly of intractable type. The results indicate that the drug therapy proved to be effective in decreasing urinary protein and controlling nephrotic condition in 40% of the cases after an initial period of treatment. Long-term results of the drug on urinary protein and on nephrotic condition were rated as good in 36.7 and 53.3%, respectively, of the cases treated. The exact mechanism of action of dipyridamole in the nephrotic syndrome is still obscure in many respects. However, the fact that the drug shares its anti-platelet action with the non-steroid anti-inflammatory drugs, e.g. aspirin and indomethacin, and the rapidity with which it produces its urinary protein-decreasing effect, strongly suggests that it inhibits the release of vasoactive amines and other chemical mediators from blood platelets. As far as the present study is concerned, adverse side effects of dipyridamole were few or minimal, even when the drug used in large doses over a prolonged period of time. From these results it is considered that dipyridamole provides a new remedy which is worthy of trying in nephrotic syndrome as a means of reducing the requirement of steroids and immunosuppressive drugs.

Abstract
BACKGROUND/OBJECTIVES Fall accidents may reduce an individual's quality of life and ability to perform the activities of daily life, and may delay recovery from illness. Consequently, medical institutions need to take measures to prevent falls. There are various risk factors for falls, including advanced age, illness and medication effects. Although hyponatremia and hypokalemia have been reported to increase the rate of falls, how they affect falls is not fully understood. SUBJECTS/METHODS We retrospectively examined 2948 patients, ⩾18 years old who had been hospitalized for ⩾3 days at Gifu (Japan) Municipal Hospital between May 2012 and April 2013 to determine the effects of hyponatremia and hypokalemia on the risk of falls. After the patients had been divided into fall and non-fall groups, their data were subjected to univariate and multiple regression analysis to identify significant differences. RESULTS The univariate analysis results revealed significant differences between the groups in terms of age (⩾65 years); the presence of hyponatremia, hypokalemia, central nervous system disease, cardiovascular disease and/or peripheral nerve/muscular disease; intake of medications that increase the risk of falls; and increased sedative dosage. The multivariate analysis results revealed significant differences between the groups in terms of the presence of hyponatremia (odds ratio (OR), 1.751; 95% confidence interval (CI), 1.020-3.005), hypokalemia (OR, 2.209; 95% CI, 1.280-3.813), central nervous system disease (OR, 2.492; 95% CI, 1.629-3.814) and/or age ⩾65 years (OR, 2.180; 95% CI, 1.242-3.826). CONCLUSIONS The results indicated that the presence of hyponatremia or hypokalemia increases the risk of falls.

Abstract
Abstract The purpose of this study was to demonstrate the radiological features of long bones in synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome and to correlate these with the clinical findings. Eleven long bone lesions in seven cases of SAPHO syndrome were examined. The patients ranged in age from 6 to 63 years, with a mean of 47 years. In all seven cases, radiography, (99m)technetium bone scintigraphy, CT scan, and magnetic resonance imaging (MRI) were performed. In six of the cases, bone biopsy and bone culture were carried out for 7 long bones. Seven of the involved lesions were from the shaft of the femur, one each was from the neck and the shaft of the humerus, and one was from the proximal tibia. These lesions showed radiologically hyperostosis, osteolysis, and bone infarction-like lesion. Osteolysis was occasionally accompanied by sclerotic change. Hyperostosis usually showed diaphyseal involvement, presenting low signal intensity on T1- and T2-weighted MR images. Histologically, these findings corresponded to massive bone necrosis, new bone formation, fibrosis, or a mixture of these associated with mild inflammatory cell infiltration. Osteolysis involved dyaphysis, metaphysis, or epiphysis associated with arthritis, and presented low signal intensity on T1-weighted images, nonhomogeneous signal intensity lower than fat on T2-weighted images, and high signal intensity on fat suppression images. These findings corresponded to fibrosis, granulation, and inflammatory cell infiltration with lymphocyte aggregation. Bone infarction-like lesion was observed in the shaft or neck of the femur and the humerus and accompanied by calcification and cystic change. Bone cultures were negative in all cases in which bone biopsy was performed. Although hyperostosis is thought to be a characteristic bone lesion in SAPHO syndrome, the long bone lesion can occasionally show not only hyperostosis but also osteolytsis and bone infarction-like lesions.

Abstract
Ensuring an appropriate dosage of renally eliminated drugs for patients with renal insufficiency is important for preventing adverse drug reactions. We investigated the effectiveness of interventions by pharmacists in a hospital pharmaceutical department. The comparative study was performed at Gifu Municipal Hospital in Japan from March to August 2011, and included an intervention (142 patients) and a control group (98 patients). Upon receiving a prescription of levofloxacin for patients aged > or = 75 years, pharmacists evaluated the patients' kidney function and adjusted the appropriate dosage at the time of dispensation. In the intervention and control groups, levofloxacin-induced adverse reactions developed in 6 of 142 (4.2%) and 13 of 98 (13.3%) patients, respectively (p < 0.05). The cost of reducing levofloxacin per patient was yen 191.1 and yen 0 in the intervention and control groups, respectively. The cost per patient for adverse reaction treatments and examinations was yen 15.5 and yen 290.0 in the intervention and control groups, respectively. The intergroup difference in the total cost per patient was yen 465.6. Dose adjustment of levofloxacin at the time of dispensation by the pharmacist for patients aged > or = 75 years resulted in a decrease in the incidence of adverse reactions and cost. These findings can be applied not only to hospitals, but also to community pharmacies, because the intervention, which is a manual system, is simply performed when pharmacists are dispensing drugs.

Abstract
Dipeptidyl peptidase-4 (DPP-4) inhibitors and other incretin-related drugs have attracted attention as antidiabetic agents, but they are expensive. The Japanese government has adopted a policy of reducing healthcare costs, and medical institutions must provide medical care while considering economic efficiency. This study was a comparative survey of the usage, treatment effectiveness, and cost of DPP-4 inhibitors. The subjects were patients prescribed DPP-4 inhibitors (sitagliptin, vildagliptin, and alogliptin) at Gifu Municipal Hospital between February 2010 and August 2011. HbA1c: Japan Diabetes Society values (%) and concomitant antidiabetic agents were surveyed for 12 weeks after the start of DPP-4 inhibitors. A cost-effectiveness analysis showed that the cost required for a 0.1% decrease in HbA1c for 12 weeks was the lowest with vildagliptin (2,478 yen; decrease in HbA1c: 0.75% +/- 0.85%). In a cost analysis with a virtual cohort of 1000 patients, the number of patients who achieved the treatment target (HbA1c 6.5%) was estimated with respect to a virtual cohort created based on the HbA1c level (7.59 +/- 1.13%) at baseline of 307 patients, in cases assuming the use of each DPP-4 inhibitor. In addition, the incremental cost-effectiveness ratio (ICER) was obtained with sitagliptin 50 mg as the reference. The number of patients achieving the treatment target was the highest with vildagliptin 100 mg (413 of 1000 patients), and the estimated ICER of 28,359 yen was the lowest. Robustness was also confirmed with a sensitivity analysis. These results suggest that vildagliptin provides a superior cost-benefit.

Abstract
Ureaplasma urealyticum could be a pathogen of non-gonococcal urethritis (NGU) in men. However, ureaplasma is often detected in men without NGU, and the proportion of cases possibly attributable to this pathogen is still undefined. We attempted to determine the bacterial loads of U. urealyticum significantly associated with NGU. The 16S rRNA genes of U. urealyticum were quantified by a real-time polymerase chain reaction-based assay in first-void urine (FVU) from 26 asymptomatic and 25 symptomatic men positive for U. urealyticum. The leucocyte counts in first-void urine (FVU) were determined as an objective measure of inflammatory response to ureaplasma in the hosts by automated quantitative urine particle analysis. Positive correlations were observed between copies of the 16S rRNA genes of U. urealyticum per ml and the leucocyte counts per µl in FVU (r = 0.49, p = 0.0003). Loads of ≥10(4) copies of the 16S rRNA gene of U. urealyticum/ml, corresponding to ≥5 × 10(3) cells of U. urealyticum/ml in FVU, were significantly associated with the presence of urethritis symptoms (p < 0.0001) and with higher leukocyte counts in FVU (p < 0.0001). The bacterial load of U. urealyticum, possibly of ≥5 × 10(3) cells of U. urealyticum/ml in FVU, could be significantly associated with the development of symptomatic NGU.

Abstract
Measures for prevention of Clostridium difficile-associated diarrhea, a common nosocomial infection, in hospital settings are urgently needed. This study was conducted to identify the risk factors contributing to C. difficile-associated diarrhea and to evaluate the clinical benefit of probiotics in its prevention. The study included 2716 patients at least 20 years old who received an injected antibiotic at any time between February 2010 and February 2011; a total of 2687 patients (98.9%) were assigned to the non-C. difficile-associated diarrhea group, and 29 patients (1.1%) were assigned to the C. difficile-associated diarrhea group. Univariate analysis revealed a significant difference between the two groups for the following factors: antibiotic therapy for > or = 8 days; enteral nutrition; intravenous hyperalimentation; fasting; proton pump inhibitor use; H2 blocker use; and serum albumin < or = 2.9g/dL (p<0.05). Multivariate logistic regression analysis revealed a significant difference between the two groups for several factors. Antibiotic therapy for > or = 8 days, intravenous hyperalimentation, proton pump inhibitor use, and H2 blocker use were therefore shown to be risk factors for C. difficile-associated diarrhea. Prophylactic probiotic therapy was not shown to suppress the occurrence of C. difficile-associated diarrhea.
