Abstract
BACKGROUND The appropriate usage of an adrenaline auto-injector (AAI, Epipen®) is a key aspect of patient and social education in the management of anaphylaxis. However, although AAIs are being prescribed increasingly frequently, there are few reports on their actual use. METHODS The Anaphylaxis Working Group of the Japanese Society of Pediatric Allergy and Clinical Immunology requested that society members register cases in which AAIs were used. Two hundred and sixty-six cases were collected from March 2014 to March 2016. RESULTS The cases included 240 events of immediate-type food allergies caused by cow's milk (n = 100), hen's egg (n = 42), wheat (n = 40), and peanuts (n = 11). Exercise-related events were reported in 19 cases; however, the diagnosis of food-dependent exercise-induced anaphylaxis with a specific causative food was only made in 4 cases (wheat, n = 2; fish, n = 1; squid, n = 1). The frequent reasons for the causative intake included programmed intake (n = 48), failure to check the food labeling (n = 43), and consuming an inappropriate food (n = 26). AAIs were used at schools or nurseries in 67 cases, with school or nursery staff members administering the AAI in 39 cases (58%). On arriving at the hospital, the symptom grade was improved in 71% of the cases, while grade 4 symptoms remained in 20% of the cases. No lethal cases or sequelae were reported. CONCLUSIONS AAIs were used effectively, even by school teachers. The need to visit a hospital after the use of an AAI should be emphasized because additional treatment might be required.

Abstract
This study investigated a case of spindle cell carcinoma (SpCC) in tongue pathological lesions. The patient experienced a local recurrence and distant metastasis after surgical intervention. Although standard chemotherapy was administered, a granulomatous mass continued to develop. This aggressive growth led to survival of the tumor. Secondary debulking surgery was performed to improve the patient's quality of life at the request of the patient. Using a tissue sample derived from the secondary debulking surgery, we performed an analysis of the tumor's cell surface antigens, differentiation potential, metastatic ability, and inhibition potential by anticancer reagents. In vitro analysis revealed that the cell population grown under adherent culture conditions expressed the mesenchymal stem cell (MSC) markers CD73, CD90, and CD105. The cell line established from this SpCC contained colony-forming unit fibroblasts (CFU-Fs) and exhibited multipotent differentiation into several mesenchymal lineages, including bone, cartilage, and fat. The SpCC cells also displayed vigorous mobilization. These characteristics suggested that they had the differentiation potential of mesenchymal cells, especially MSCs, rather than that of epithelial cells. The surgical specimen analyzed in this study resisted the molecular target reagent cetuximab, which is an epidermal growth factor receptor inhibitor. This clinical insight revealed that chemotherapy-resistant SpCC cells have different characteristics compared to most other cancer cells, which are sensitive to cetuximab. Our cell death assay revealed that SpCC cell death was induced by the anticancer drug imatinib, which is known to inhibit protein tyrosine kinase activity of ABL, platelet-derived growth factor receptor α (PDGFRα), and KIT. Here, we report recurrent SpCC with characteristics of MSCs and potential for treatment with imatinib.

Abstract
BACKGROUND This study aimed to evaluate the clinical accuracy of specific IgE (sIgE) to Ara h 2 in the diagnosis of peanut allergy (PA). We also investigated the prevalence of complications with other nut allergies in PA patients. METHODS The Ara h 2-sIgE titer was examined in patients with positive results for sIgE to peanut from April 2014 to March 2015. The presence or absence of PA was diagnosed based on an oral food challenge or a convincing clinical history. The characteristics of 217 patients (including 90 PA patients) were retrospectively evaluated. RESULTS At ≥0.35UA/mL, Ara h 2 showed 85.6% sensitivity in the diagnosis of PA. At the clinically-designated positive cut-off value (≥4.0UA/mL), the positive predictive value was 93.1% and the specificity was 96.9%. However, the Ara h 2-sIgE levels were not correlated with the threshold dose or the severity of the symptoms that were provoked in the peanut challenge (n=42). Nine (10%) of the PA patients also had allergies to other tree nuts. CONCLUSION The re-evaluation of the clinically-designated positive Ara h 2-sIgE cut-off value revealed that the cut-off value was appropriate. The differential diagnosis of tree nut allergies was suggested to be important in PA patients.

Abstract
BACKGROUND Significance of monitoring adalimumab trough levels and anti-adalimumab antibodies (AAA) for disease outcome in Crohn's disease (CD) patients remained unclear. AIM To evaluate the association of adalimumab trough levels and AAA at week 26 with clinical remission at week 52, the effect of azathiopurine on AAA and factors influencing trough levels in CD patients in the DIAMOND trial. METHODS We performed this study using adalimumab trough levels, AAA at week 26 and 6-thioguanine nucleotide (TGN) in red blood cells at week 12. A multiple regression model and receiver operating analysis was performed to identify factors influencing adalimumab trough levels and AAA, and adalimumab thresholds for predicting disease activity. RESULTS There was a significant difference of adalimumab trough level at week 26 between patients with disease remission and without at week 52 (7.7 ± 3.3 μg/mL vs 5.4 ± 4.3 μg/mL: P <.001). Adalimumab trough level of 5.0 μg/mL yielded optimal sensitivity and specificity for remission prediction (80.2% and 55.6%, respectively). AAA development at week 26 significantly affected remission at week 52 (P = .021), which was strongly associated with adalimumab trough levels. Female gender and increasing body weight were independently associated with low adalimumab trough levels, and female gender was associated with AAA development. A cut-off 6TGN level of >222.5 p mol/8 ×108 RBCs yielded sensitivity (100%) and specificity (60.6%) for AAA negativity. CONCLUSION Adalimumab trough levels and AAA occurrence were significantly associated with clinical remission. Higher 6TGN affected AAA negativity. The combination therapy is beneficial in some relevant aspects for CD patients. (UMIN Registration No. 000005146).

Abstract
Osteosarcoma (OSA) in dogs is locally invasive and highly malignant. Distant metastasis is the most common cause of death. To date, the survival rate in dogs with OSA remains poor. The cytotoxic effects of etoposide against canine OSA cell lines, either alone or in combination with piroxicam, have been previously demonstrated in vitro. The aim of this study was to evaluate the anti-tumour effect of etoposide alone and in combination with piroxicam on canine OSA using murine models. Etoposide single agent treatment significantly delayed tumour progression with a marked reduction in Ki-67 immunoreactivity in tumour tissue. Concomitant treatment with piroxicam did not enhance the anti-tumour efficacy of etoposide. Etoposide single agent treatment and combination treatment with piroxicam down-regulated survivin expression, but was not followed by increased apoptotic activity. These findings indicate that etoposide might be a promising novel therapeutic for canine OSA. Further investigations into its potential for clinical application in veterinary oncology are warranted.

Abstract
BACKGROUND The diagnosis of the progression of periodontitis presently depends on the use of clinical symptoms (such as attachment loss) and radiographic imaging. The aim of the multicenter study described here was to evaluate the diagnostic use of the bacterial content of subgingival plaque recovered from the deepest pockets in assessing disease progression in chronic periodontitis patients. METHODS This study consisted of a 24-month investigation of a total of 163 patients with chronic periodontitis who received trimonthly follow-up care. Subgingival plaque from the deepest pockets was recovered and assessed for bacterial content of Porphyromonas gingivalis, Prevotella intermedia, and Aggregatibacter actinomycetemcomitans using the modified Invader PLUS assay. The corresponding serum IgG titers were measured using ELISA. Changes in clinical parameters were evaluated over the course of 24 months. The sensitivity, specificity, and prediction values were calculated and used to determine cutoff points for prediction of the progression of chronic periodontitis. RESULTS Of the 124 individuals who completed the 24-month monitoring phase, 62 exhibited progression of periodontitis, whereas 62 demonstrated stable disease. The P. gingivalis counts of subgingival plaque from the deepest pockets was significantly associated with the progression of periodontitis (p < 0.001, positive predictive value = 0.708). CONCLUSIONS The P. gingivalis counts of subgingival plaque from the deepest pockets may be associated with the progression of periodontitis.

Abstract
OBJECTIVE Ameloblastoma (AM) shows locally invasive behaviour. However, biological investigations regarding regulation of gene expression associated with AM pathological features are difficult to perform, because AM cells can be passaged for a few generations due to senescence. We report a newly established immortalized AM cell line, AMB cells, by transfection with human telomerase reverse transcriptase (hTERT). Furthermore, we examined whether TNF-α modulates bone resorption-related genes, IL-6 and MMP-9 in cooperation with TGF-β or IFN-γ. MATERIALS AND METHODS Following transfection of an hTERT expression vector into AM cells using a non-viral method, the effects of cytokines on the expressions of IL-6 and MMP-9 mRNA were examined using real-time PCR. TNF-α-induced NF-κB activity was examined by western blotting and transcription factor assays. RESULTS AMB cells continued to grow for more than 100 population doublings. Stimulation with TNF-α increased IL-6 and MMP-9 mRNA expressions, as well as NF-κB activation. Furthermore, TGF-β and IFN-γ dramatically increased TNF-α-mediated expressions of MMP-9 and IL-6 mRNA, respectively, while those responses were suppressed by NF-κB inhibitor. CONCLUSION We established an immortalized AM cell line by hTERT transfection. TNF-α-mediated regulation of MMP-9 and IL-6 via NF-κB may play an important role in the pathological behaviour of AMs, such as bone resorption.

Abstract
Osteosarcoma (OSA) is the most common primary bone tumour in dogs. The poor survival rate in dogs with OSA highlights the need for new therapeutic approaches. This study evaluated the cytotoxic effects of etoposide, alone and in combination with piroxicam, on canine OSA cell cultures. Etoposide alone significantly suppressed cell growth and viability, whereas etoposide in combination with piroxicam exhibited concentration dependent cytotoxicity. The anti-proliferative effect was a result of inactivity of the Cdc2-cyclin B1 complex, which correlated with an increase in the G2/M fraction. This subsequently activated the apoptosis cascade, as indicated by elevated apoptosis levels and up-regulation of poly (ADP-ribose) polymerase proteolytic cleavage. Down-regulation of survivin expression induced by the combination treatment may have contributed to the enhanced cytotoxicity. The results of this study suggest that further investigation of etoposide and piroxicam as a therapeutic combination for canine OSA is warranted.

Abstract
BACKGROUND The number of reported cases of allergic reactions to sesame seeds (Sesamum indicum) has increased significantly. The specific IgE tests and skin prick tests presently available for diagnosis of sesame allergy are all based on crude sesame extract and are limited by their low clinical specificity. Thus, oral food challenge (OFC) is still the gold standard in the diagnosis. OBJECTIVE The aim was to identify the allergen components useful to diagnose sesame-allergic children with the goal to reduce the number of OFCs needed. METHODS Ninety-two sesame-sensitized children were consecutively enrolled and diagnosed based on OFC or convincing history. Specific IgE to purified native 11S globulin (nSes i 11S), 7S globulin (nSes i 7S), 2S albumin (nSes i 2S), and two recombinant 2S albumins (rSes i 1 and rSes i 2) was measured by ELISA and/or ImmunoCAP (rSes i 1/streptavidin application). RESULTS Based on area under curve (AUC) values from receiver operating characteristic (ROC) analysis, rSes i 1 was shown to have the best diagnostic performance of the allergen components in ELISA. The experimental rSes i 1 ImmunoCAP test had larger AUC (0.891; 95% CI, 0.826-0.955) compared to the commercially available sesame ImmunoCAP (0.697; 95% CI, 0.589-0.805). The clinical sensitivity and specificity for the rSes i 1 ImmunoCAP test at optimal cut-off (3.96 kUA /L) were 86.1% and 85.7%, respectively. CONCLUSION AND CLINICAL RELEVANCE Sensitization to Ses i 1 is strongly associated with clinical sesame allergy. Measurement of specific IgE to rSes i 1 could reduce the numbers of OFCs needed.

Abstract
Råde considered a parallel system with n components in a random environment. The shocks cause the components to fail with certain probabilities. This paper considers the replacement policy for the above system in which it is exchanged before failure if the total number of failed components is more than k, and it is replaced if all of n components have failed. An optimum number of k which will minimize the expected cost is obtained. A numerical example is finally presented.
