Abstract
Spiroplasma (Mycoplasmatales: Spiroplasmataceae) is one of the most widely distributed symbionts of arthropods. Spiroplasma species can infect their hosts via vertical or horizontal transmission. However, the mode of transmission of Spiroplasma between different arthropod taxa has not been elucidated. In this study, we investigated the potential for the transmission of Spiroplasma to non-native arthropod species, using 2 Spiroplasma spp. isolated from ticks, namely Spiroplasma ixodetis and Spiroplasma mirum, and 3 species of mosquito laboratory colonies, namely Aedes albopictus, Aedes aegypti, and Culex pipiens pallens (Diptera: Culicidae). After feeding the adult mosquitoes with Spiroplasma-containing artificial meals, they were kept at 25 °C for 10 days. Homogenates prepared from Spiroplasma-fed mosquitoes were used to re-isolate Spiroplasma using the in vitro culture method. Nine weeks after culture initiation, the presence of Spiroplasma was tested using the polymerase chain reaction (PCR). The results revealed that only S. ixodetis was detected from all 3 species of mosquitoes and re-isolated from 2 of them. The differences in the infection ability of different Spirolasma species could be attributed to several factors, including environmental effects. Nevertheless, this is the first experimental demonstration of Spiroplasma transmission among different arthropod taxa. Further studies are needed to elucidate the evolutionary mechanism that supports the survival of Spiroplasma in nature.

Abstract
Many arthropods harbour bacterial symbionts, which are maintained by vertical and/or horizontal transmission. Spiroplasma is one of the most well-known symbionts of ticks and other arthropods. It is still unclear how Spiroplasma infections have spread in tick populations despite its high prevalence in some tick species. In this study, Ixodes ovatus, which has been reported to harbour Spiroplasma ixodetis at high frequencies, was examined for its vertical transmission potential under experimental conditions. Next, two isolates of tick-derived Spiroplasma, S. ixodetis and Spiroplasma mirum, were experimentally inoculated into Spiroplasma-free Haemaphysalis longicornis colonies and the presence of Spiroplasma in their eggs and larvae was tested. Our experimental data confirmed that S. ixodetis was transmitted to eggs and larvae in a vertical manner in the original host I. ovatus. In the second experiment, there was no significant difference in engorged weight, egg weight, and hatching rate between Spiroplasma-inoculated and control H. longicornis groups. This suggested that Spiroplasma infection does not affect tick reproduction. Spiroplasma DNA was only detected in the eggs and larvae derived from some individuals of S. ixodetis-inoculated groups. This has demonstrated the potential of horizontal transmission between different tick species. These findings may help understand the transmission dynamics of Spiroplasma in nature and its adaptation mechanism to host arthropod species.

Abstract
OBJECTIVES The hospitalisation rate for work-related injuries among older workers is double that of younger workers; however, the risk factors for same-level fall fractures sustained during industrial accidents remain unclear. This study aimed to estimate the influence of worker age, time of day and weather conditions on the risk of same-level fall fractures in all industrial sectors in Japan. STUDY DESIGN This was a cross-sectional study. METHODS This study used the population-based national open database of worker death and injury reports in Japan. In total, 34,580 reports of occupational same-level falls between 2012 and 2016 were used in this study. Multiple logistic regression analysis was performed. RESULTS In primary industries, workers aged ≥55 years had a 1.684 times greater risk of fracture (95% confidence interval [CI]: 1.167-2.430) compared with workers aged ≤54 years. In tertiary industries, relative to the odds ratio (OR) of injuries recorded at 0:00-2:59 a.m., the ORs recorded at 6:00-8:59 p.m., 6:00-8:59 a.m., 9:00-11:59 p.m. and 0:00-2:59 p.m. were 1.516 (95% CI: 1.202, 1.912), 1.502 (95% CI: 1.203-1.876), 1.348 (95% CI: 1.043-1.741) and 1.295 (95% CI: 1.039-1.614), respectively. The risk of fracture increased with a 1-day increase in the number of snowfall days were per month in secondary (OR = 1.056, 95% CI: 1.011-1.103) and tertiary (OR = 1.034, 95% CI: 1.009-1.061) industries. The risk of fracture decreased with every 1-degree increase in the lowest temperature in primary (OR = 0.967, 95% CI: 0.935-0.999) and tertiary (OR = 0.993, 95% CI: 0.988-0.999) industries. CONCLUSIONS With the increasing number of older workers and changing environmental conditions, the risk of falls in the tertiary sector industries is increasing, particularly just before and just after shift change hours. These risks may be associated with environmental obstacles during work migration. It is also important to consider the weather-associated risks of fracture.

Abstract
Malawi has an estimated cattle population of 1,884,803 heads, the indigenous Malawi zebu breed accounts for 91.2%, while the exotic and crossbred accounts for the remaining 8.8%. Although ticks and tick-borne diseases are widespread in Malawi, no molecular study has been conducted to investigate the tick-borne Anaplasmataceae and piroplasms infecting cattle. To provide an insight into the current status of tick-borne pathogens (TBPs) of cattle, a molecular survey was conducted in the central and southern regions of Malawi. A total of 191 cattle of which 132 were Malawi zebu, 44 were Holstein Friesian and 15 were Holstein-Friesian/ Malawi zebu crosses were screened for Anaplasmataceae and piroplasms using the heat shock protein groEL gene and 18S rDNA, respectively. A new 18S rDNA multiplex PCR assay was designed for Babesia and Theileria species identification without sequencing. Overall, 92.3% (n = 177) of the examined animals were infected with at least one TBP. Anaplasmataceae-positive rate was 57.6% (n = 110) while for piroplasms it was 80.1% (n = 153). The detected Anaplasmataceae were Anaplasma bovis 2.6% (n = 5), Anaplasma marginale 24.6% (n = 47), Anaplasma platys-like 13.6% (n = 26), uncharacterized Anaplasma sp. 14.1% (n = 27), and uncharacterized Ehrlichia sp. 16.2% (n = 31). The detected piroplasms were Babesia bigemina 2.6% (n = 5), Theileria mutans 73.8% (n = 141), Theileria parva 33.0% (n = 63), Theileria taurotragi 12.6% (n = 24), and Theileria velifera 53.4% (n = 102). Mixed infection rate was found in 79.6% (n = 152) of the samples analyzed. This study has shown a high burden of TBPs among cattle in Malawi which highlights the need to conceive new methods to control ticks and TBPs in order to improve animal health and productivity. The newly developed multiplex PCR assay would be a useful tool especially in resource limited settings where sequencing is not available and when mixed infections are expected.

Abstract
Ticks are the second most important vector capable of transmitting diseases affecting the health of both humans and animals. Amblyomma testudinarium Koch 1844 (Acari: Ixodidae), is a hard tick species having a wide geographic distribution in Asia. In this study, we analyzed the composition of A. testudinarium whole mitogenomes from various geographical regions in Japan and investigated the population structure, demographic patterns, and phylogeographic relationship with other ixodid species. In addition, we characterized a potentially novel tick species closely related to A. testudinarium from Myanmar. Phylogeographic inference and evolutionary dynamics based on the 15 mitochondrial coding genes supported that A. testudinarium population in Japan is resolved into a star‐like haplogroup and suggested a distinct population structure of A. testudinarium from Amami island in Kyushu region. Correlation analysis using Mantel test statistics showed that no significant correlation was observed between the genetic and geographic distances calculated between the A. testudinarium population from different localities in Japan. Finally, demographic analyses, including mismatch analysis and Tajima’s D test, suggested a possibility of recent population expansion occurred within Japanese haplogroup after a bottleneck event. Although A. testudinarium has been considered widespread and common in East and Southeast Asia, the current study suggested that potentially several cryptic Amblyomma spp. closely related to A. testudinarium are present in Asia.

Abstract
Latin American countries produce more than a quarter of the world's beef and are a major global supplier of livestock protein. Tick-borne diseases (TBDs) are a major constraint to the livestock industry worldwide, including in Latin America. The aim of this study was to detect and characterise tick-borne pathogens in cattle from Santa Cruz, Bolivia, where no detailed epidemiological data are available. Blood samples were collected from 104 cattle. Apicomplexan parasites were detected by nested PCR amplification of the 18S ribosomal RNA gene (rDNA), and Anaplasmataceae was screened by the PCR amplification of 16S rDNA, followed by characterisation based on the heat shock protein and citrate synthase gene sequences. Babesia infection was observed in nine cattle (one Babesia bovis and eight Babesia bigemina), while Anaplasmataceae infection was detected in thirty-two cattle. A sequencing analysis confirmed the presence of Anaplasma marginale and Anaplasma platys-like. These results provide the first molecular evidence for the four above-mentioned tick-borne pathogens in cattle in Bolivia. This information improves our understanding of the epidemiology of TBDs and will help in formulating appropriate and improved pathogen control strategies.

Abstract
Haploinsufficiency of A20 (HA20) causes inflammatory disease resembling Behçet's disease; many cases have been reported, including some that are complicated with autoimmune diseases. This study aims to clarify the immunophenotype of patients with HA20 by analyzing lymphocyte subsets using multicolor flow cytometry. The patients with HA20 previously diagnosed in a nationwide survey were compared by their cell subpopulations. In total, 27 parameters including regulatory T cells (Tregs), double-negative T cells (DNTs), and follicular helper T cells (TFHs) were analyzed and compared with the reference values in four age groups: 0-1, 2-6, 7-19, and ≥20 years. The Tregs of patients with HA20 tended to increase in tandem with age-matched controls at all ages. In addition, patients ≥20 years had increased DNTs compared with controls, whereas TFHs significantly increased in younger patients. In HA20 patients, the increase in DNTs and TFHs may contribute to the development of autoimmune diseases.

Abstract
IMPORTANCE Few studies with sufficient statistical power have shown the association of the z score of the coronary arterial internal diameter with coronary events (CE) in patients with Kawasaki disease (KD) with coronary artery aneurysms (CAA). OBJECTIVE To clarify the association of the z score with time-dependent CE occurrence in patients with KD with CAA. DESIGN, SETTING, AND PARTICIPANTS This multicenter, collaborative retrospective cohort study of 44 participating institutions included 1006 patients with KD younger than 19 years who received a coronary angiography between 1992 and 2011. MAIN OUTCOMES AND MEASURES The time-dependent occurrence of CE, including thrombosis, stenosis, obstruction, acute ischemic events, and coronary interventions, was analyzed for small (z score, <5), medium (z score, ≥5 to <10; actual internal diameter, <8 mm), and large (z score, ≥10 or ≥8 mm) CAA by the Kaplan-Meier method. The Cox proportional hazard regression model was used to identify risk factors for CE after adjusting for age, sex, size, morphology, number of CAA, resistance to initial intravenous immunoglobulin (IVIG) therapy, and antithrombotic medications. RESULTS Of 1006 patients, 714 (71%) were male, 341 (34%) received a diagnosis before age 1 year, 501 (50%) received a diagnosis between age 1 and 5 years, and 157 (16%) received a diagnosis at age 5 years or older. The 10-year event-free survival rate for CE was 100%, 94%, and 52% in men (P < .001) and 100%, 100%, and 75% in women (P < .001) for small, medium, and large CAA, respectively. The CE-free rate was 100%, 96%, and 79% in patients who were not resistant to IVIG therapy (P < .001) and 100%, 96%, and 51% in patients who were resistant to IVIG therapy (P < .001), respectively. Cox regression analysis revealed that large CAA (hazard ratio, 8.9; 95% CI, 5.1-15.4), male sex (hazard ratio, 2.8; 95% CI, 1.7-4.8), and resistance to IVIG therapy (hazard ratio, 2.2; 95% CI, 1.4-3.6) were significantly associated with CE. CONCLUSIONS AND RELEVANCE Classification using the internal diameter z score is useful for assessing the severity of CAA in relation to the time-dependent occurrence of CE and associated factors in patients with KD. Careful management of CE is necessary for all patients with KD with CAA, especially men and IVIG-resistant patients with a large CAA.

Abstract
BACKGROUND While genetic influences on chronic pain have been repeatedly demonstrated, we do not know whether these effects are stable or dynamic over time. AIMS To determine the temporal pattern of genetic and environmental effects to individual differences in chronic pain over 12 years, we use a sample of n = 961 female twins. METHODS Data on chronic pain were collected in 2004 (T1) and 2016 (T2) using the same comprehensive body map which divides the body into 31 distinct anatomical areas. Multivariate twin analyses for repeated measures were conducted to track changes in genetic and environmental influences. RESULTS Heritability for chronic pain was 63% at baseline and 55% at follow-up. The best-fitting AE Cholesky model revealed one genetic factor explaining 62% of variance in chronic pain at T1 and 11% at T2. No additional genetic factors explaining the variance in chronic pain at T2 could be detected. Furthermore, a unique environmental factor (E1) explaining 37% of the variance in chronic pain at T1 and 12% at T2 and an additional environmental factor (E2) explaining 77% of the variance at T2 were found. CONCLUSION We demonstrate for the first time that the same genetic influences are operative over time and that novel environmental factors are important in pain maintenance. The findings highlight the value of more in depth exploration of these non-shared environmental influences that could provide clues to the mechanisms behind remittance and/or maintenance of chronic pain. The identification of important environmental influences could point to novel therapeutic interventions in future. SIGNIFICANCE The variability in chronic pain is mainly explained by new environmental factors influencing incidence, aggravation and/or chronic pain remission. Integration of these findings may provide a useful conceptual framework for the treatment and prevention of pain and pain chronification.

Abstract
OBJECTIVE To assess the clinical utility and safety of a strategy for refractory Kawasaki disease, defined by Egami score ≥3. STUDY DESIGN First-line treatment was with intravenous methylprednisolone (30 mg/kg, 2 hours, 1 dose) plus intravenous immunoglobulin (2 g/kg, 24 hours) treatment. Patients resistant to first-line treatment received additional intravenous immunoglobulin as a second-line treatment. Patients resistant to second-line treatment who had received Bacillus Calmette-Guérin vaccination 6 months earlier were treated with infliximab; otherwise, plasma exchange was performed. A total of 71 refractory patients with Kawasaki disease (median age: 2.4 years) of 365 patients with Kawasaki disease were treated according to our strategy from April 2007 to April 2016. Treatment resistance was defined as a persistent fever at 36 hours after treatment. We evaluated coronary artery lesions at the time of the diagnosis, at 1 month, and at 1 year after the diagnosis in accordance with the American Heart Association guidelines and the criteria of the Japanese Ministry of Health, Labour, and Welfare. RESULTS First-line therapy was effective for 58 of 71 patients (81.6%), and second-line therapy was effective for 9 of 13 patients (69.2%). At third line, 3 patients were treated by infliximab, and 1 was treated with plasma exchange. Of the 18 patients with coronary artery abnormalities at diagnosis, 13 patients at 1 month and 6 patients at 1 year had coronary artery dilatation (median z score 3.0, 2.6, and 1.4, respectively). There were no patients with coronary artery aneurysm (CAA). CONCLUSIONS Our strategy for refractory Kawasaki disease was safe and effective in preventing CAA.

Abstract
BACKGROUND A Japanese nationwide survey has reported that Down syndrome (DS) is a less-frequently occurring comorbidity in Kawasaki disease (KD). Although altered immune responses are frequently observed in DS, no studies have focused on the treatment response and risk for coronary artery abnormalities (CAA) in DS patients with KD. The aim of this study was therefore to evaluate the clinical manifestations, treatment response and prevalence of CAA in DS with KD. METHODS We retrospectively reviewed the medical records of DS patients with KD from 2005 through 2012. The survey questionnaires were sent to facilities nationwide, and clinical data regarding KD in DS were collected. A control group consisted of non-DS patients with KD who were managed at Toho University. RESULTS Of the 94 233 children diagnosed with acute KD from 2005 to 2012, 16 children with acute KD also had DS (0.017%). The DS-KD patients were significantly older than the non-DS patients (median, 8 years vs 1 year, P < 0.05, respectively). Half of the DS patients had incomplete KD. Although 50% of the DS children were at high risk of immunoglobulin resistance, all children responded to initial treatment and none had CAA. CONCLUSIONS All DS-KD patients responded to initial i.v. immunoglobulin (IVIG) or aspirin despite having a high risk of IVIG resistance, and none of the DS patients had CAA. This suggests that the risk of treatment resistance and development of CAA may be not higher in DS patients with acute KD.

Abstract
BACKGROUND Increased tender spots and lowered general pain thresholds have been observed in patients with dyspareunia. Based on this, the aim of the study was to compare the co-occurrence of female sexual pain across various pain populations and to further explore the aetiological structure underlying sexual pain by dissecting the genetic and environmental covariation among sexual pain, chronic widespread pain (CWP) and the previously reported psychological correlates of anxiety sensitivity and depression. METHODS A multivariate twin study including 1489 female twin individuals (246 full MZ pairs, 187 full DZ pairs and 623 whose co-twin did not participate). Main outcomes measures included self-reported diagnosis of osteoarthritis and rheumatoid arthritis, and validated questionnaires for the assessment of sexual pain, CWP, depression and anxiety sensitivity. RESULTS Sexual pain showed a small but statistically significant correlation with CWP (r = 0.08; p < 0.05), anxiety sensitivity (r = 0.15, p < 0.001) and depression (r = 0.09, p < 0.01). The heritability of sexual pain was found to be 31%. Multivariate variance component analysis revealed a genetic factor common among CWP, depression, anxiety sensitivity and sexual pain, and a second genetic factor shared between anxiety sensitivity and sexual pain only. We further detected genetic and environmental factors unique to sexual pain, explaining 24.01% and 67.24%, respectively, of the phenotypic variance. CONCLUSIONS Our findings suggest some overlap between sexual pain and CWP and point towards a shared but complex psychophysiological aetiology underlying sexual pain. Results further highlight the influence of specific environmental and contextual stressors in the development and maintenance of sexual pain. SIGNIFICANCE Sexual pain shares a common genetic aetiology with chronic widespread pain and the frequently reported psychological comorbidities of depression and anxiety. Overall this suggests a complex psychophysiological aetiology underlying chronic pain conditions. The high proportion of variance in sexual pain explained by environmental factors further highlights the importance of specific environmental and contextual stressors in the development and maintenance of the condition.

Abstract
Interleukin-1α(IL-1α) stimulates the production of prostaglandin E2 (PGE2) in odontogenic keratocyst fibroblasts. However, the signaling pathways remain obscure. In this study, we investigated IL-1αsignaling pathways that regulate cyclooxygenase-2 (COX-2) expression in odontogenic keratocyst fibroblasts. IL-1αincreased the expression of COX-2 mRNA and protein, and PGE2 secretion in the fibroblasts. IL-1αincreased the phosphorylation of extracellular signal-regulated protein kinase-1/2 (ERK1/2), p38 mitogen-activated protein kinase (MAPK), and c-Jun N-terminal kinase (JNK). PD-98059, SB-203580, SP-600125, and PDTC—which are inhibitors of ERK1/2, p38, JNK, and nuclear factor-κB (NF-κB), respectively—attenuated the IL-1α-induced COX-2 mRNA expression and activated protein kinase C PGE2 secretion. IL-1α(PKC), and PKC inhibitor staurosporine inhibited IL-1α-induced phosphorylation of ERK1/2, p38, and JNK, and decreased IL-1α-induced COX-2 mRNA expression. Thus, in odontogenic keratocyst fibroblasts, IL-1αmay stimulate COX-2 expression both through the PKC-dependent activation of ERK1/2, p38, and JNK signaling pathways, and through the NF-κB cascade.

Abstract
Intracystic fluid pressure is thought to be involved in odontogenic cyst growth. In this study, we investigated the effects of positive pressure on the expression of interleukin-1α (IL-1α), matrix metalloproteinases (MMPs), and prostaglandin E2 (PGE2) in odontogenic keratocysts to determine whether this pressure stimulates inflammatory cytokine production and signaling of osteoclastogenic events. Positive pressure enhanced the expression of IL-1α mRNA and protein in odontogenic keratocyst epithelial cells, and increased the secretion of MMP-1, MMP-2, MMP-3, and PGE2 in a co-culture of odontogenic keratocyst fibroblasts and the epithelial cells. The pressure-induced secretions were inhibited by an interleukin-1 receptor antagonist. Recombinant human interleukin-1α (rhIL-1α) increased the secretion of MMP-1, MMP-2, MMP-3, and PGE2 in the fibroblasts. Furthermore, in the fibroblasts, rhIL-1α enhanced the expression of macrophage colony-stimulating factor (M-CSF) mRNA, and rhIL-1α-induced PGE2 increased the expression of nuclear factor κB ligand (RANKL) mRNA. Thus, positive pressure may play a crucial role in odontogenic keratocyst growth via stimulating the expression of IL-1α in epithelial cells.

Abstract
BACKGROUND Autoimmune diseases in children are rare and can be difficult to diagnose. Autoimmune lymphoproliferative syndrome (ALPS) is a well-characterized pediatric autoimmune disease caused by mutations in genes associated with the FAS-dependent apoptosis pathway. In addition, various genetic alterations are associated with the ALPS-like phenotype. OBJECTIVE The aim of the present study was to elucidate the genetic cause of the ALPS-like phenotype. METHODS Candidate genes associated with the ALPS-like phenotype were screened by using whole-exome sequencing. The functional effect of the identified mutations was examined by analyzing the activity of related signaling pathways. RESULTS A de novo heterozygous frameshift mutation of TNF-α-induced protein 3 (TNFAIP3, A20), a negative regulator of the nuclear factor κB pathway, was identified in one of the patients exhibiting the ALPS-like phenotype. Increased activity of the nuclear factor κB pathway was associated with haploinsufficiency of TNFAIP3 (A20). CONCLUSION Haploinsufficiency of TNFAIP3 (A20) by a germline heterozygous mutation leads to the ALPS phenotype.

Abstract
Severe combined immunodeficiency (SCID) is the most severe form of primary immunodeficiency disease, and it is characterized by marked impairment in cellular and humoral immunity. Mutations in several genes cause SCID, one of which is Janus kinase 3 (JAK3), resulting in autosomal recessive T(-)B(+)NK(-) SCID. Only three patients with JAK3-deficient SCID have been reported in Japan. We herein describe the case of a 6-month-old girl with pneumocystis pneumonia, who was diagnosed with SCID with compound heterozygous JAK3 mutations (c.1568G>A + c.421-10G>A). One of the mutations was previously reported in another Japanese patient. The other mutation was a novel and de novo relatively deep intronic mutation causing aberrant RNA splicing. The patient was successfully treated with bone marrow transplantation from a haploidentical donor.

Abstract
BACKGROUND The best time for vaccination in infants with congenital heart disease (CHD) after cardiopulmonary bypass (CPB) surgery is unclear, but it is important to prevent Haemophilus influenzae type b (Hib) infection in infants with CHD after CPB surgery. To identify the best time for Hib vaccination in infants with CHD after CPB surgery, we investigated the immunological status, and the efficacy and safety of Hib vaccination after CPB surgery. METHODS Sixteen subjects who underwent surgical correction of ventricular septal defect with CPB were investigated. Immunological status and cytokines were analyzed before surgery, 2 months after surgery, and before Hib booster vaccination. Hib-specific IgG was also measured to evaluate the effectiveness of vaccination. RESULTS Immunological status before and 2 months after surgery (e.g. whole blood cells and lymphocyte subset profile) was within the normal range and no subjects had hypercytokinemia. Additionally, all subjects who received Hib vaccination at 2-3 months after CPB surgery had effective serum Hib-specific IgG level for protection against Hib infection without any side-effects. CONCLUSIONS CPB surgery does not influence acquired immunity and Hib vaccination may be immunologically safe to perform at 2 months after CPB surgery. Hib vaccination at 2-3 months after CPB surgery was effective in achieving immunization for infants with simple left-right shunt-type CHD.

Abstract
This study was conducted to quantify the genetic and environmental contributions to oral disease and function in twins. Participants were middle-aged and old twins, 116 monozygotic and 16 dizygotic pairs whose mean age was 66·1 ± 10·3 (SD) years. Number of teeth, percentage of decayed, filled and missing teeth and periodontal status were recorded as indicators of oral disease. The widths of upper and lower dental arch served as indicators of morphological figures. Furthermore, stimulated salivary flow rate, occlusal force and masticatory performance were measured as indicators of oral function. Univariate genetic analysis with monozygotic and dizygotic twin pairs was conducted to detect the fittest structural equation model of each outcome. Both number of teeth and periodontal status fitted the model composed of common environmental factor and unique environmental factor. Decayed, filled and missing teeth, morphological figures and measurements of oral function fitted the model composed of additive genetic factor and unique environmental factor. The model fitting of each measurement suggested that periodontal disease was mainly affected by environmental factors, while morphological figures and oral functions were influenced by both genetic and environmental factors.

Abstract
Kawasaki disease(KD) is an acute, self-limited vasculitis of unknown etiology that predominantly affects infants and children. Coronary artery(CA) aneurysms, the most severe complication, occur in 25 % of untreated children and may lead to ischemic heart disease, myocardial infarction, or sudden death. While a single high dose of intravenous immunoglobulin (IVIG) terminates the fever and acute inflammation in most subjects and dramatically reduces the incidence of CA aneurysms, 10 to 20 % of KD patients are IVIG- resistant and these subjects are at higher risk of developing CA abnormalities. Several mechanisms have been reported for the anti-inflammatory activity of IVIG in different disease states. In this review, we describe the clinical utility and these mechanisms of IVIG in KD.

Abstract
BACKGROUND Infliximab (IFX), a known monoclonal antibody against tumor necrosis factor-α (TNF-α), is used to treat Kawasaki disease (KD) patients with intravenous immunoglobulin (IVIG) resistance. The transcriptional modulation of inflammation following IFX therapy has not been reported in KD patients. METHODS We investigated the transcript abundance profiles in whole blood obtained from eight IVIG-resistant KD subjects treated with IFX therapy using microarray platforms and compared them with those in initially IVIG-responsive subjects. A pathway analysis was performed using WikiPathways to search for the biological pathways of the transcript profiles. Four transcripts changed by IFX therapy were subsequently validated using quantitative real-time polymerase chain reaction. RESULTS The pathway analysis showed the reduced abundance of transcripts in the nucleotide-binding oligomerization domain, matrix metalloproteinase (MMP), and inflammatory cytokine pathways and the increased abundance of transcripts in the T-cell receptor, apoptosis, TGF-β, and interleukin-2 pathways. Additionally, the levels of four transcripts (peptidase inhibitor-3, MMP-8, chemokine receptor-2, and pentraxin-3) related to KD vasculitis and IVIG resistance decreased after IFX therapy. CONCLUSION The administration of IFX was associated with both the signaling pathways of KD inflammation and several transcripts related to IVIG resistance factors. These findings provide strong theoretical support for the use of IFX in KD patients with IVIG resistance.

Abstract
The structure of a 1.6-kb SphI-HindIII DNA sequence necessary and sufficient for the replication of a 8.6-kb plasmid pLS11 of Bacillus subtilis IFO 3022, which is responsible for gamma-polyglutamate production, has been characterized by using a trimethoprim (Tmp)-resistance gene derived form B. subtilis TTK24 chromosomal DNA as a selective marker. The 1.6-kb DNA sequence contains a rep gene encoding the protein (333 amino acids) essential for initiation of replication and a possible origin of replication. The predicted REP protein of pLS11 has an overall homology with the REP proteins of pUH1 (74.8% identity), pBAA1 (92.8%), and pFTB14 (78.7%) in Bacillus spp., pLP1 (42.1%) and pLAB1000 (36.3%) in Lactobacillus spp., and pUB110 (35.3%) and pC194 (37.4%) in Staphylococcus aureus, but has not any similarity with the REP protein of the staphylococcal plasmid pT181.

Abstract
Objectives Although intravenous immunoglobulin (IVIG) is highly effective in Kawasaki disease (KD), mechanisms are not understood and 10-20% of patients are treatment-resistant, manifesting a higher rate of coronary artery aneurysms. Murine models suggest that α2-6-linked sialic acid (α2-6Sia) content of IVIG is critical for suppressing inflammation. However, pro-inflammatory states also up-regulate endogenous levels of β-galactoside:α2-6 sialyltransferase-I (ST6Gal-I), the enzyme that catalyzes addition of α2-6Sias to N-glycans. We asked whether IVIG failures correlated with levels of α2-6Sia on infused IVIG or on the patient’s own endogenous IgG. Methods We quantified levels of α2-6Sia in infused IVIG and endogenous IgG from 10 IVIG-responsive and 10 resistant KD subjects using multiple approaches. Transcript levels of ST6GAL1, in patient whole blood and B cell lines were evaluated by RT-PCR. Plasma soluble (s)ST6Gal-I levels were measured by ELISA. Results There was no consistent difference in median sialylation levels of infused IVIG between groups. However, α2-6Sia levels in endogenous IgG, ST6GAL1 transcript levels, and ST6Gal-I protein in serum from IVIG-resistant KD subjects were lower than in responsive subjects at both pre-treatment and one-year time points (p <0.001, respectively). Conclusions Our data indicate sialylation levels of therapeutic IVIG are unrelated to treatment response in KD. Rather, lower sialylation of endogenous IgG and lower blood levels of ST6GALI mRNA and ST6Gal-I enzyme predict therapy resistance. These differences were stable over time, suggesting a genetic basis. Because IVIG-resistance increases risk of coronary artery aneurysms, our findings have important implications for the identification and treatment of such individuals.

Abstract
Severe dull pain on the side of tourniquet application and marked rises in blood pressure and heart rate associated with that pain are often observed even under adequate regional analgesia. The purpose of this study was to evaluate the effect of epidural fentanyl on the suppression of tourniquet pain during orthopedic surgical procedures. Forty-five patients undergoing orthopedic surgery of the lower extremities with a tourniquet were maintained by continuous epidural anesthesia with 2% lidocaine through an epidural indwelling polyethylene catheter (L3-4). The patients were randomly allocated to the following three groups: epidural fentanyl (100μg) (epidural group,n=15); intravenous fentanyl (100μg) (intravenous group,n=15); control (no fentanyl) (control group,n=15). The epidural or intravenous fentanyl was administered at the time of the second lidocaine injection. The severity of tourniquet pain based on the patient's level of complaint and the total dose of supplemental analgesics requested in the epidural group were significantly lower than those in the control group. Blood pressure during tourniquet application in the epidural group was more stable than in the other two groups. No severe side-effects were observed in any patient. Prophylactic epidural administration of fentanyl might be useful in the suppression of tourniquet pain.

Abstract
OBJECTIVE It has been claimed that the aneurysm rate for Kawasaki disease (KD) patients in Japan is lower than in the U.S. However it has been difficult to compare coronary artery (CA) outcomes between the two countries because of different definitions for CA abnormalities. Therefore, we compared CA internal diameters between Japanese and U.S. KD patients using standard definitions and methods. STUDY DESIGN We retrospectively reviewed CA outcomes in 1082 KD patients from 2 centers in the U.S. and 3 centers in Japan and compared Z-max scores (maximum internal diameter for the left anterior descending or right coronary artery expressed as standard deviation units from the mean (Z-score) normalized for body surface area) obtained within 12 weeks after onset and calculated using two different regression equations from Canada (Dallaire) and Japan (Fuse). We defined a Z-max of < 2.5 as normal and a Z-max of ≥ 10 as giant aneurysm. RESULT The median Z-max for the U.S. and Japanese subjects was 1.9 and 2.3 SD units, respectively (p < 0.001). There was no significant difference in rates of patients with Z-max ≥ 5.0 between the countries. In a multivariable model adjusting for age, sex, and treatment response, being Japanese was still associated with a higher Z-max score. CONCLUSION Previously reported differences in aneurysm rates between Japan and the U.S. likely resulted from use of different definitions and nomenclature. Adoption of Z-scores as a standard for reporting CA internal diameters will allow meaningful comparisons among different countries and will facilitate international, collaborative clinical trials.

Abstract
Hemolytic uremic syndrome (HUS) is a life-threatening infectious disease in childhood for which there is no confirmed therapeutic strategy. Endothelial inflammation leading to microthrombosis formation via complement activation is the main pathology of HUS. Thrombomodulin is an endothelial membrane protein that has anticoagulation and anti-inflammatory effects, including the suppression of complement activity. Recombinant human soluble thrombomodulin (rTM) is a novel therapeutic medicine for disseminated intravascular coagulation. We administered rTM to 3 patients with HUS for 7 days and investigated the outcomes in view of the patients' prognoses, changes in biochemical markers, complications, and adverse effects of rTM. Symptoms and laboratory data improved after initiation of rTM in all 3 patients. Abnormal activation of complements was also dramatically suppressed in 1 patient. The patients recovered without any complications or adverse effects of rTM. They were discharged having normal neurologic status and with no renal dysfunction. To our knowledge, this is the first report of rTM being used to treat HUS. These case reports show the positive effect of rTM in patients with HUS. Randomized controlled studies should be performed to assess the efficacy and safety of rTM for children with HUS.

Abstract
AIMS/HYPOTHESIS Medical nutrition therapy plays a critical role in the prevention and treatment of type 2 diabetes. However, appropriate measures of eating behaviours, such as eating rate, have not yet been clearly established. The aim of the present study was to examine the associations among eating rate, obesity and cardiovascular risk factors. METHODS A total of 7,275 Japanese individuals aged ≥40 years who had normal fasting glucose levels, impaired fasting glucose or diabetes were divided into four groups according to self-reported eating rate: slow, medium, relatively fast and very fast. The associations between eating rate and various cardiovascular risk factors were investigated cross-sectionally. RESULTS The proportions of participants who were obese or who had elevated waist circumference levels increased progressively with increases in eating rate (p for trend <0.001), regardless of glucose tolerance status. These associations remained significant after adjustment for potential confounders, namely, age, sex, total energy intake, dietary fibre intake, current smoking, current drinking and regular exercise (p for trend <0.001). Blood pressure and lipid levels also tended to increase in association with eating rate. HbA(1c) rose significantly as eating rate increased, even after multivariate adjustment, including BMI, in diabetic patients on insulin therapy (p = 0.02), whereas fasting plasma glucose did not increase significantly. CONCLUSIONS/INTERPRETATION Our findings suggest that eating rate is associated with obesity and other cardiovascular risk factors and therefore may be a modifiable risk factor in the management of cardiovascular risk factors and diabetes.

Abstract
An increased risk of testicular cancer in men with infertility and poor semen quality has been reported. In view of the high cure rates for testicular germ cell tumours, increasing clinical importance is being placed on the protection of fertility. High-dose cytostatic therapy may be expected to cause long-term infertility. Thus, the standard procedure for fertility protection is the cryopreservation of ejaculated spermatozoa or testicular tissue before therapy. Four male patients with azoospermia and two patients with very severe oligozoospermia underwent onco-testicular sperm extraction (TESE). We attempted onco-TESE in patients with azoospermia and very severe oligozoospermia after orchiectomy. Of the patients with testicular germ cell tumours, four had spermatozoa in their testicular tissues. Sertoli cell-only syndrome was found in one patient, and one patient showed maturation arrest without the detection of spermatozoa. Three of six showed seminomatous germ cell tumour, two of six had nonseminomatous germ cell tumour and one patient showed no malignancy. Two patients achieved clinical pregnancy. Fertility challenges in men with cancer are the most straightforward because of the relative ease of obtaining and cryopreserving sperm. Testicular sperm extraction is a useful technique for obtaining spermatozoa before cytotoxic therapy in azoospermic and very severely oligozoospermic cancer patients.

Abstract
OBJECTIVE This study examined the clinical efficacy and safety of intravenous methylprednisolone-pulse plus intravenous immunoglobulin (IVIG) combination therapy (IVMP+IVIG) for the initial treatment of patients predicted to have refractory Kawasaki disease (KD). METHODS One hundred twenty-two patients with KD were studied at Kitasato University. Refractory KD was predicted at diagnosis using the Egami score, and the patients were randomly divided to receive either IVMP+IVIG or IVIG alone. The Egami score is used to predict refractory KD patients before treatment using the patient's age, days of illness, platelet count, C-reactive protein, and alanine aminotransferase level (cutoff: ≥3 points; 78% sensitivity and 76% specificity). RESULTS Forty-eight patients (39.3%) were predicted to have refractory KD on the basis of the Egami score. The predicted IVIG responders (n = 74) received the standard therapy. The 48 predicted refractory KD patients were randomly assigned to a single-IVIG group (n = 26) or an IVMP+IVIG group (n = 22). Nineteen of the 22 patients (86.4%) in the IVMP+IVIG group had a prompt defervescence compared with 6 of the 26 patients (23.1%) in the single-IVIG group. The number of patients who had a z score ≥2.5 at 1 month was significantly higher in the single-IVIG group than in the IVMP+IVIG group. No serious adverse events were observed in either treatment group. CONCLUSION This study demonstrated that IVMP+IVIG therapy is safe and effective for KD patients predicted as refractory.

Abstract
BACKGROUND The accurate evaluation of pulmonary vascular resistance (PVR) and mean pulmonary artery pressure is important to determine the optimal management and therapeutic strategy for patients with congenital heart disease (CHD). We evaluated the PVR and mean pulmonary artery pressure in 46 patients with several CHD types using the interventricular septum (IVS) motion determined by M-mode echocardiography. METHODS We divided the patients into 2 groups according to the different IVS motions. We measured the maximum anterior displacement from the baseline during early systole (a) and the maximum posterior displacement from the baseline during early diastole (b). We defined type A to be a/b greater than or equal to 1.0, and type B to be a/b less than 1.0. RESULTS The PVR and mean pulmonary artery pressure in type A patients were significantly higher than those in type B patients (p < 0.05). Type A IVS motion predicted patients with high PVR (>2.5 unit/m(2)) and high mean pulmonary artery pressure (>25 mmHg) (sensitivity 89%, specificity 89% and sensitivity 70%, specificity 91%, respectively). CONCLUSIONS Our method can noninvasively separate high and low PVR among patients with CHD. This noninvasive method is therefore considered to be useful in the management of patients with CHD in a clinical setting.

Abstract
Slope (or plate) cultures of thiostrepton-producing Streptomyces azureus (ATCC 14921) often showed spontaneously developing plaques. Plaques increased in number during serial subcultures. The production of aerial mycelia and sporulating aerial hyphae was interrupted by the overlapping plaques, whereas the growth of substrate mycelia continued in the plaques. These abnormal (eroded) cultures were easily restored to their normal conditions once they were passed through liquid cultures under shaking conditions. A few phage particles were found in the plaques, together with some headless tails and numerous tail tips which formed a hexagonal crystal or a large crystal mass when viewed in an electron microscope. No lytic phenomenon and no phage production were found in the liquid cultures, although all mycelia and spores harbored phage-producing abilities. It was also found that the propagation of phages was successful in solid culture, but not in liquid culture. The whole phage was named SAt2, which belongs to group B of Bradley's morphological classification. From these results, it is considered that S. azureus is lysogenic with temperate phage SAt2, of which virulent mutants are able to infect the aerial mycelia and sporulating hyphae of their lysogenic host.

Abstract
Plate (or slope) cultures of endomycin-producing Streptomyces endus (KCC S-0213) showed spontaneously developing pocks which increased in number during subculturing. Neither spore formation nor typical aerial hyphae formation was observed in the pocks, whereas formation of substrate hyphase was not inhibited. Almost all of the hyphae were broken or lysed in the pocks, and many phage tail tiplike particles were observed in the pocks. No self-replication activity was associated with the particles. The particles often formed a hexagonal crystal or a large crystal mass. The production of these particles did not occur in the liquid culture or in young or normal plate cultures having no pocks. These results were similar to those obtained from the plaque-making phenomenon, except for active phage production, in thiostrepton-producing Streptomyces azureus (ATCC 14921), which has been described previously.

Abstract
AIM Protein kinase C (PKC), cloned as a serine/threonine kinase, plays key roles in diverse intracellular signalling processes and in cardiovascular remodelling during pressure overload or volume overload. We looked for correlations between changes in PKC isoforms (levels and/or subcellular distributions) and cardiac remodelling during experimental hypobaric hypoxic environment (HHE)-induced pulmonary hypertension. METHODS To study the PKC system in the heart during HHE, 148 male Wistar rats were housed for up to 21 days in a chamber at the equivalent of 5500 m altitude level (10% O(2)). RESULTS At 14 or more days of exposure to HHE, pulmonary arterial pressure (PAP) was significantly increased. In the right ventricle (RV): (1) the expression of PKC-alpha protein in the cytosolic and membrane fractions was increased at 3-14 days and at 5-7 days of exposure respectively; (ii) the cytosolic expression of PKC-delta protein was increased at 1-5, 14 and 21 days of exposure; (3) the membrane expressions of the proteins were decreased at 14-21 (PKC-betaII), 14-21 (PKC-gamma), and 0.5-5 and 21 (PKC-epsilon) days of exposure; (4) the expression of the active form of PKC-alpha protein on the plasma membrane was increased at 3 days of exposure (based on semiquantitative analysis of the immunohistochemistry). In the left ventricle, the expressions of the PKC mRNAs, and of their cytosolic and membrane proteins, were almost unchanged. The above changes in PKC-alpha, which were strongly evident in the RV, occurred alongside the increase in PAP. CONCLUSION PKC-alpha may help to modulate the right ventricular hypertrophy caused by pulmonary hypertension in HHE.

Abstract
We report herein the pathological findings and clinical courses of two cases of Kikuchi-Fujimoto disease (KFD) that developed into autoimmune diseases. The patients are currently undergoing treatment for a disease similar to Sjogren's syndrome and systemic lupus erythematosus/mixed connective tissue disease. KFD is not an independent condition and most likely develops due to an autoimmune mechanism. Pediatricians should pay careful attention to KFD and encourage long-term follow-up in patients with this condition.
