Abstract
Bullous pemphigoid (BP) is a rare autoimmune blistering disease, and the prevalence of type 2 diabetes mellitus (T2DM) is relatively high in subjects with BP. It is known that dipeptidyl peptidase-4 inhibitor (DPP-4i), one kind of antidiabetic drugs, can cause BP, although precise mechanism of DPP-4i-related BP remains unclear. In this report, we showed a case with appearance of various disease-specific antibodies after the onset of DPP-4i-related BP. Furthermore, various disease-specific antibodies became positive and showed high titers two years after the onset of DPP-4i-related BP and discontinuation of DPP-4i. These data showed that it is possible for immune tolerance to be broken after the onset of DPP-4i-related BP, and it may be important to check autoimmune antibodies in DPP-4i-related BP subjects even when BP symptoms are improved.

Abstract
Many cases of bullous pemphigoid (BP) have been reported in patients taking dipeptidyl peptidase-4 inhibitors (DPP-4i), which are the most widely used antidiabetic drug for type 2 diabetes mellitus. However, no large-scale survey has been conducted in Japan. This retrospective study investigated the incidence, clinical presentation, and clinical course of DPP-4i-associated BP (DPP-4i-BP) using epidemiological data from a nationwide registry for BP. In 2016, 713 new BP patients at 94 dermatological institutes were registered, 243 (34.1%) with DPP-4i-BP and 461 (64.7%) with non-DPP-4i-BP. The male-to-female ratio was 1.9 and 0.84, respectively. Patients with DPP-4i-BP were predominantly male. Non-inflammatory BP was more common in DPP-4i-BP (33.3%) than in non-DPP-4i-BP (14.6%), while inflammatory BP was common in both. No specific subtype or difference in disease severity was evident in DPP-4i-BP. The most common gliptins administered to DPP-4i-BP patients were vildagliptin (37.2%) and linagliptin (23.8%). DPP-4i intake was discontinued in 79.9% of cases after diagnosis. Some DPP-4i-BP patients (17.6%) achieved spontaneous remission after discontinuing DPP-4i without requiring the use of systemic corticosteroids and/or adjuvant therapy. Mean duration to achieve disease control was 2.87 months. The odds ratio for non-inflammatory BP requiring systemic corticosteroids and/or adjuvant therapy was low (0.52), suggesting that remission was achieved easily with supportive care in that phenotype. Non-inflammatory and mild cases of DPP-4i-BP may resolve spontaneously with supportive care, including the discontinuation of DPP-4i and no oral corticosteroid therapy.

Abstract
Non-HIV immune reconstitution inflammatory syndrome (non-HIV IRIS) is associated with the recovery from an immunocompromised condition. It is defined as inflammatory disorders caused by antigens, including drugs or pathogenic microorganisms present prior to immune recovery, or by the exacerbation of an inflammatory disorder that was already present. Drug-induced hypersensitivity syndrome is a prototype of IRIS, and the pathophysiology of non-HIV IRIS can be recognized in several disorders treated with corticosteroids, immunosuppressants, molecular-targeted drugs, TNF-α antibody drugs, immune checkpoint inhibitors, and dipeptidyl peptidase-4 inhibitors. This review focuses on the relationship between the immune mechanism of non-HIV IRIS and drug allergies, especially severe drug eruption. The antigen recognition mechanism in drug allergy varies depending on the clinical type and the causative drug. The p-i concept is the main mechanism in severe drug eruption such as Stevens-Johnson syndrome/toxic epidermal necrolysis, and drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms. Lymphocytes activated by an antigen other than a drug, such as a virus, can also develop drug allergy by the loose binding of drugs with immune receptors of T cells or human leukocyte antigen. Therefore, fluctuations in the immune environment affect the onset of severe drug eruption. Novel agents that cause major changes in immunity have been marketed mainly for autoimmune diseases and malignant tumors; therefore, it is necessary to consider their effects when treating severe drug eruptions. Moreover, although a list of diagnostic criteria for this syndrome has been drafted, predictive and diagnostic biomarkers for this syndrome needs to be urgently developed.

Abstract
Aim We developed and psychometrically tested the Japanese version of the Professional Attitude Scale for Nurses (PASN‐J). Background Nurses must recognize the importance of their professionalism; therefore, it is critical to quantitatively measure nurses’ professional attitudes. Introduction This instrument validation study was designed to generate an itemized scale and examine its content validity/psychometric testing using a sample of Japanese nurses. Methods Based on a trait approach focusing on the characteristic traits of the nursing profession, a 59‐item draft scale was generated. During November 2017, 2657 nurses from 29 facilities in Japan were surveyed. The questionnaire included demographics, the 59‐item draft scale, and a self‐report scale of nurses’ professional behaviour and nursing practice ability. Using exploratory and confirmatory factor analyses, we evaluated the construct, criterion‐related, concurrent, and known‐groups validity, and reliability of the PASN‐J. Results Data from 1716 participants were analysed. The analyses yielded a 38‐item, 3‐factor scale that adequately fit the data. PASN‐J scores were positively correlated with nurses’ professional behaviour and nursing practice ability. Conclusion The 38‐item PASN‐J has good reliability and validity, making it useful for measuring the current condition of nursing professionalism and evaluating nursing education. Implications for Nursing and Health Policy: This scale can evaluate nursing education and promote nurses’ professionalism. The PASN‐J will help identifying the elements of undergraduate nursing education that require further emphasis. Additionally, the PASN‐J could facilitate the development of nursing policies to promote professional development in nurses. Ultimately, evaluating nursing education with the PASN‐J enhances nurses’ professional attitudes and subsequently improves their quality of nursing, nursing efficiency and patient outcomes.

Abstract
Programmed death 1 (PD-1) inhibitors are increasingly used for the treatment of malignancies. Despite the clinical benefits, unpredictable and potentially fatal side-effects may occur. We report a psoriatic patient who developed systemic capillary leak syndrome (SCLS) after starting a PD-1 checkpoint inhibitor. In order to determine which factors could trigger the development of SCLS in a patient with stable psoriasis after starting anti-PD-1 therapy, serum cytokines were serially measured before and after the development of SCLS in this patient. We also retrospectively reviewed 28 previously reported patients presenting clinical exacerbations of pre-existing psoriasis or the de novo induction of psoriasis after anti-PD-1 therapy. In 16 of the 28 patients (57.1%), the interval between last anti-PD-1 therapy and exacerbations of pre-existing psoriasis or the de novo induction of psoriasis was less than 28 days. The timing of the onset of SCLS in this patient was coincident with the increase in lymphocyte counts and at 22 days after last anti-PD-1 therapy. In 75%, however, anti-PD-1 therapy was able to be restarted and was tolerated well. Increased levels of interleukin (IL)-2, IL-6, interferon-γ and tumor necrosis factor-α, in addition to a persistent increase in vascular endothelial growth factor (VEGF), were detected at onset of SCLS. An increase in pro-inflammatory cytokines and VEGF, when combined with a rapid and sequential recovery of neutrophils and lymphocytes after anti-PD-1 therapy, would predict the development of SCLS. Clinicians need to be aware that patients with psoriasis are at risk of a potentially fatal disease, SCLS, when anti-PD-1 therapy is started.

Abstract
Little attention has been given to the involvement of sweat glands/ducts in the pathogenesis of prurigo nodularis (PN). According to recent studies, PN is likely to develop under conditions characterized by dry skin, such as atopic dermatitis (AD), suggesting a strong impact of skin dryness on PN development. No therapeutic modalities produced complete resolution of PN without exacerbations. We previously reported that increases in skin dryness by sweating disturbance could initiate the development of AD. We investigated whether sweating responses were impaired in refractory PN lesions; and, if so, we asked whether the PN lesions could resolve by restoring sweating disturbance. Using the impression mold technique, which allows an accurate quantification of individual sweat gland/duct activity, we examined basal sweating under quiescent conditions and inducible sweating responses to thermal stimulus in PN lesions and normal-appearing skin in the same patients before and after treatment with a moisturizer or topical corticosteroids. Sweating disturbance, either basal or inducible, was most profoundly detected in the "hub" structure corresponding to the center of PN papule before the treatment. This sweating disturbance was immunohistochemically associated with the leakage of sweat into the dermis. This disturbance was restored by treatment with a moisturizer. Our limitations include a relatively small patient cohort and lack of blinding. Sweating disturbance could be one of the aggravating factors of PN development. Refractory PN with low skin hydration may resolve by restoring sweating disturbance.

Abstract
Background This in vitro study aimed to clarify the combined effect of electric toothbrushing and dentifrice on the removal of artificial stain. Material and Methods Twenty-five bovine incisors were cut at the cervix and the crown was embedded in auto-cured acrylic resin. Specimens were abraded using #240 SiC paper to obtain a flat enamel surface, and 20 specimens were treated with 10% citric acid / 3% ferric chloride solution followed by 1% tannic acid solution to produce surface staining. They were divided into four groups: 1) brushing with an electric toothbrush and whitening dentifrice (group S+B); 2) brushing with an electric toothbrush and fluoride dentifrice (group S+C); 3) brushing with an electric toothbrush and no dentifrice (group S); and 4) no brushing (control group). The remaining five specimens were used as a baseline. Color values (L*, a*, and b* were measured before brushing (0 min), and at 1 min, 5 min, 10 min, and 20 min using a microscopic area spectrophotometer. The color change (ΔE) was calculated by subtracting the baseline values from the final color values obtained at each time point. The data were statistically analyzed using two-way repeated-measures analysis of variance and Tukey’s honest significant difference test as a post hoc test (p<0.05). Results The L* values of groups S+B and S+C increased over time (p<0.05), but no significant differences were observed in group S and the control group at any of the time points (p>0.05). Groups S+B and S+C demonstrated greater ΔE values than group S. Conclusions The combination of electric toothbrushing and dentifrice removed the artificial stain more effectively than brushing without dentifrice. However, the stain removal was limited. The two dentifrices evaluated in this study exhibited similar stain removal effects. Key words:Color change, stain removal, dentifrice, electric toothbrush, whitening effect.

Abstract
BACKGROUND AND AIMS Fish consumption is a recognized risk factor for elevated serum uric acid (UA) levels, hyperuricemia, and gout. However, the relationship between the consumption of fish cooked by different methods and the risk of hyperuricemia is unclear. Therefore, we aimed to investigate the relationship between the consumption of fish cooked by different methods and the risk of hyperuricemia in Japanese adults. METHODS AND RESULTS A 3-year follow-up study was conducted with 424 Japanese adults aged 29-74 years. Fish consumption was assessed using a validated self-administered dietary history questionnaire, and hyperuricemia was defined as serum UA ≥7 mg/dL in men and ≥6 mg/dL in women or the use of any anti-gout treatment. During the 3-year follow-up period, we documented 30 newly diagnosed cases of hyperuricemia. After adjusting for potential confounders, multivariate logistic regressions analysis revealed a significant positive relationship between the risk of hyperuricemia and raw (sashimi and sushi) or roasted fish consumption, but not boiled or fried fish consumption. The odds ratios (95% CI) for hyperuricemia with increasing raw fish consumption were 1.00 (reference), 2.51 (0.85, 7.39), and 3.46 (1.07, 11.14) (P for trend: 0.036). Similarly, the odds ratios (95% CI) with increasing roasted fish consumption were 1.00 (reference), 3.00 (0.75, 11.89), and 5.17 (1.30, 20.62) (P for trend: 0.018). CONCLUSION This 3-year follow-up study showed that the consumption of raw or roasted fish, but not boiled or fried fish, was related with a higher risk of hyperuricemia in Japanese adults.

Abstract
BACKGROUND Optimal design of stents for a cerebral aneurysm is desired for efficient flow reduction in the aneurysm. OBJECTIVE In this study, we aimed to optimize stent design at several porosities, estimate the influence of stent design on aneurysm flow, and evaluate the ability of stents to reduce flow. METHODS Stent models were constructed as sets of squares or rectangles in the necks of a two-dimensional (2D) and realistic aneurysm. Then, automated optimization was performed using a combination of simulated annealing and lattice Boltzmann flow simulation. RESULTS By simulated annealing, stents were gradually modified to reduce the average velocity in an aneurysm. As a result of optimization, stents of all porosities demonstrated an inhomogeneous distribution with dense struts in the inflow area. Flow reduction was increased compared with the initial stent. Under the condition of high porosity, flow reduction by the stent drastically increased as porosity decreased. Under low porosity, the increase of velocity reduction was moderate even as porosity decreased. CONCLUSIONS Optimization can enhance flow reduction by stents. However, the increase in reduction associated with decreasing porosity is moderate under lower-porosity conditions. This threshold may help in the choice of stent porosity for each specific aneurysm.

Abstract
Administering 15N-labelled glycine, 15 N incorporation into serum albumin and its excretion into urine and feces, together with nitrogen balance were investigated in 3 nephrotic and 2 normal adults. Furthermore, 15N-labelled urea was injected into a nephrotic adult and a glomerulonephritic adult, both advanced in azotemia and treated on low protein diet, and a normal subject on a normal diet, to examine the amounts of 15N incorporation into serum albumin. In the 3 nephrotic patients whose nitrogen balance was almost maintained, incorporation of 15N-glycine into serum albumin has been proved greater than in the normal subjects. In any of the above patients, 15N excretion into urine was less than in the normal subjects. Fecal 15N excretion was 2.0--2.5 % of the doses, indicating that approximately 98 % of 15N-glycine was absorbed. In the nephrotic patients, 15N incorporation into serum albumin examined by 15N-labelled urea administration was more accelerated than in the glomerulonephritic patients and was negligible in the control subject on a normal diet.

Abstract
BACKGROUND AND PURPOSE Rupture risk assessment for intracranial aneurysms remains challenging, and risk factors, including wall shear stress, are discussed controversially. The primary purpose of the presented challenge was to determine how consistently aneurysm rupture status and rupture site could be identified on the basis of computational fluid dynamics. MATERIALS AND METHODS Two geometrically similar MCA aneurysms were selected, 1 ruptured, 1 unruptured. Participating computational fluid dynamics groups were blinded as to which case was ruptured. Participants were provided with digitally segmented lumen geometries and, for this phase of the challenge, were free to choose their own flow rates, blood rheologies, and so forth. Participants were asked to report which case had ruptured and the likely site of rupture. In parallel, lumen geometries were provided to a group of neurosurgeons for their predictions of rupture status and site. RESULTS Of 26 participating computational fluid dynamics groups, 21 (81%) correctly identified the ruptured case. Although the known rupture site was associated with low and oscillatory wall shear stress, most groups identified other sites, some of which also experienced low and oscillatory shear. Of the 43 participating neurosurgeons, 39 (91%) identified the ruptured case. None correctly identified the rupture site. CONCLUSIONS Geometric or hemodynamic considerations favor identification of rupture status; however, retrospective identification of the rupture site remains a challenge for both engineers and clinicians. A more precise understanding of the hemodynamic factors involved in aneurysm wall pathology is likely required for computational fluid dynamics to add value to current clinical decision-making regarding rupture risk.

Abstract
BACKGROUND The serum Krebs von der Lungen-6 (KL-6) level is a useful marker correlated with the severity of various interstitial lung diseases. There have been few reports about the clinical characteristics of organizing pneumonia (OP) associated with the serum KL-6 levels. OBJECTIVE This study was performed to determine whether the serum KL-6 levels can help determine the optimal treatment for OP. DESIGNS Patients diagnosed with OP by clinical, radiological and histopathological findings were retrospectively reviewed. The OP patients were classified into two groups based on their serum KL-6 levels: normal KL-6 and high KL-6 groups. The two groups were compared with regard to their clinical and radiological data and therapeutic response one month after the start of treatment. RESULTS The clinical records of twenty-two patients diagnosed with OP were reviewed. The serum KL-6 level was elevated in 11 of the 22 patients. There were no obvious differences in the clinical data between the two groups, although patients in the normal KL-6 group tended to have a fever. There were no significant differences in the chest X-ray (CXR) score or computed tomography (CT) score between the two groups. The CXR scores were correlated with the serum KL-6 levels. At 1 month after the diagnosis, 11 patients who needed treatment with prednisolone were included in the high KL-6 group. CONCLUSIONS Patients with normal KL-6 levels showed lower CXR and CT scores. The serum KL-6 level on admission is a useful marker to judge the need for corticosteroid treatment in OP patients.

Abstract
BACKGROUND AND PURPOSE The prevalence and topography of small hypointense foci suggesting microbleeds on 3T SWI in various types of dementia have not been systematically investigated. The purpose of this study was to determine the prevalence and topography of SHF on 3T SWI in patients with different dementia subtypes. MATERIALS AND METHODS We included 347 consecutive patients (217 women, 130 men; age range, 42-93 years; mean age, 74 years) who attended our memory clinic and underwent 3T SWI. They were divided into 6 groups: subjective complaints, MCI, AD, DLB, VaD, and FTLD. Two neuroradiologists evaluated the number and location of SHF on SWIs. Statistical analyses were performed to evaluate inter- and intragroup differences. RESULTS Of the 347 patients, 160 (46.1%) exhibited at least 1 small hypointense focus. This was true in 86% with VaD, 54% with DLB, 48% with AD, 41% with MCI, 27% with FTLD, and 22% with subjective complaints. With the subjective complaints group as a reference, the odds ratio adjusted by age, sex, and arterial hypertension was 9.2 (95% CI, 2.0-43.6) for VaD; 5.4 (95% CI, 1.2-24.3) for AD; 3.1 for DLB (95% CI, 1.1-8.8); 2.0 for MCI (95% CI, 0.5-8.1); and 1.5 for FTLD (95% CI, 0.4-5.4). There was a significant lobar predilection for AD, DLB, and FTLD groups (P < .05). CONCLUSIONS On 3T SWI, patients with VaD, AD, and DLB manifested a high SHF prevalence. In patients with AD, DLB, and FTLD, the SHF exhibited a lobar predilection.

Abstract
Japanese paddy rice systems commonly adopt the rotation of vegetables, wheat and soybeans with paddy rice. Crop rotation may, however, increase the nutrient load in effluent discharged from the district because more fertilizer is applied to the rotation crops than is applied to paddy crops. We investigated a paddy-field district subject to collective crop rotation and quantified the annual nutrient load of effluent from the district in three consecutive years. The total annual exports of nitrogen and phosphorus over the investigation period ranged from 30.3 to 40.6 kg N ha(-1) and 2.62 to 3.13 kg P ha(-1). The results suggest that rotation cropping increases the effluent nutrient load because applied fertilizer is converted to nitrate, and surface runoff is increased due to the absence of shuttering boards at the field outlets.

Abstract
BACKGROUND/AIMS Rapid removal of plasma amyloid-β (Aβ) by blood purification may serve as a peripheral Aβ sink from the brain for Alzheimer's disease therapy. We investigated the reduction of plasma Aβ during hemodialysis and cognitive states. METHODS Aβ concentrations and Mini-Mental State Examinations (MMSE) were investigated in 37 hemodialysis patients (68.9 ± 4.1 years). RESULTS The dialyzers effectively removed Aβ(1-40) and Aβ(1-42), 63.9 ± 14.4 and 51.6 ± 17.0% at 4 h dialysis, resulting in the reduction of Aβs in whole-body circulation by 51.1 ± 8.9 and 32.7 ± 12.0%, respectively. Although the plasma Aβs before dialysis (750.8 ± 171.3 pg/ml for Aβ(1-40)) were higher than those reported for Alzheimer's disease patients, the cognitive states of hemodialysis patients were relatively normal, especially of longer dialysis vintages. CONCLUSIONS Dialyzers effectively reduced Aβs in whole-body circulation. Repeated rapid decrease of plasma Aβs might maintain cognitive state.

Abstract
A complementary DNA (cDNA) macroarray was developed for simultaneous detection of 12 different potato viruses. A suitable region in the viral genome for each was selected for Alfalfa mosaic virus, Cucumber mosaic virus, Potato aucuba mosaic virus, Potato leafroll virus, Potato mop-top virus, Potato virus A, Potato virus M, Potato virus S, Potato virus X, Potato virus Y, Tomato ringspot virus, and Tomato spotted wilt virus, and their respective cDNAs were cloned into plasmid vectors. Capture probes for each virus ranging from 290 to 577 bp were generated by polymerase chain reaction (PCR) and immobilized on a nylon membrane. Total RNAs were extracted from each of these virus infected-plants, and cDNAs were synthesized from the RNA extracts using a random 9-mer primer. Subsequently, PCR reactions were performed using one primer pair for each of the 12 viruses. During PCR, amplified cDNAs were labeled with biotin and used as a target for hybridization analyses on a macroarray membrane. Hybridization signals between capture probes for the 12 viruses and their respective target cDNAs were observed using chemiluminescent or colorimetric detection. In all viruses, hybridization signals with capture probes were detected only when homologous virus targets were examined, and no hybridization to healthy plant extract was observed, facilitating identification of each virus. The results by colorimetric detection agreed with those obtained using chemiluminescence. The macroarray method developed was 5 × 102 to 4 × 106 times more sensitive than enzyme-linked immunosorbent assay and 5 to 5 × 104 times more sensitive than reverse-transcription PCR, except for Alfalfa mosaic virus. Colorimetric detection and substantial reduction in cross-hybridization signals much improved the method compared with other array-based detection methods for practical use.

Purpose: Spontaneous hemopneumothorax (SHP) is a rare life threatening disorder. We retrospectively investigated patients with SHP who were treated with video- assisted thoracic surgery (VATS), and report our results. Methods: From January 1993 to July 2006, 239 patients with spontaneous pneumothorax were treated, among whom 11 (4.6%) were diagnosed with SHP. Results: All 11 patients had a collapsed lung condition worse than moderate and a chest tube inserted, of whom 10 underwent an emergency operation. The points of hemorrhaging, each of which were in the apical portion of the lung, were easily revealed during VATS, and we were able to distinguish between brisk flow and seepage. Hemostasis was acquired using VATS in all surgery cases, while the other was treated with tube drainage. The single patient who did not undergo surgical treatment had recurrent spontaneous pneumothorax 3 months later. Conclusion: It is important to perform surgery for SHP at the appropriate time. VATS was found to be an easily performed and safe procedure for initial treatment in patients with active hemorrhaging and massive blood clotting in the thorax. The long-term outcome of our patients with early surgical indication was excellent and we recommend early surgical treatment for SHP.
