Abstract
Only a few years have passed since the discovery of polar nematics, and now they are becoming the most actively studied liquid-crystal materials. Despite numerous breakthrough findings made recently, a theoretical systematization is still lacking. In the present paper, we take a step toward systematization. The powerful technique of molecular-statistical physics has been applied to an assembly of polar molecules influenced by electric field. Three polar nematic phases were found to be stable at various conditions: the double-splay ferroelectric nematic N_{F}^{2D} (observed in the lower-temperature range in the absence of or at low electric field), the double-splay antiferroelectric nematic N_{AF} (observed at intermediate temperature in the absence of or at low electric field), and the single-splay ferroelectric nematic N_{F}^{1D} (observed at moderate electric field at any temperature below transition into paraelectric nematic N and in the higher-temperature range (also below N) at low electric field or without it. A paradoxical transition from N_{F}^{1D} to N induced by application of higher electric field has been found and explained. A transformation of the structure of polar nematic phases at the application of electric field has also been investigated by Monte Carlo simulations and experimentally by observation of polarizing optical microscope images. In particular, it has been realized that, at planar anchoring, N_{AF} in the presence of a moderate out-of-plane electric field exhibits twofold splay modulation: antiferroelectric in the plane of the substrate and ferroelectric in the plane normal to the substrate. Several additional subtransitions related to fitting the confined geometry of the cell by the structure of polar phases were detected.

Emergence of paraelectric, improper antiferroelectric, and proper ferroelectric nematic phases in a liquid crystal composed of polar molecules. Phys Rev E 2022; 105:064701.

Abstract
We have elaborated a theoretical approach for the description of polar nematic phases observed by Nishikawa et al. [Adv. Mater. 29, 1702354 (2017)0935-964810.1002/adma.201702354], their structures, and transitions between them. Specific symmetry contributions to the pair molecular potentials provide the molecular mechanisms responsible for the formation of proper and improper polarity on the macroscopic level. An improper antiferroelectric nematic M2 phase can arise between paraelectric nematic M1 and proper ferroelectric nematic MP in the temperature scale. The local polarization in M2 arises mostly due to the local splay deformation. The director distribution in M2 represents the conjugation of cylindrical waves with opposite splay and polarization signs. The director and polarization are parallel to the cylindrical domain axes in the middle of each cylinder but exhibit considerable (mostly radial) deformation on the periphery of each cylinder. Polarization vectors are mostly stacked antiparallel on the borders between the domains without the director disruption. The domain size decreases with the decreasing temperature, the percentage of the antiferroelectric decouplings increases, and M2 exhibits the first-order phase transition into proper ferroelectric MP. With the increasing temperature the domain size in the M2 phase increases, the domination of particular polar orientation of molecules reduces, and finally, the domain size diverges at particular temperature corresponding to the second-order phase transition from M2 to paraelectric M1. Variations of the polar and nonpolar orientational order parameters are estimated within each phase and between the phases. Our experimental and computer simulation results (also presented in the paper) fully support our theoretical findings.

Abstract
Abstract
Background/Introduction
New-onset of atrial fibrillation (AF) portends poor prognosis in patients with primary mitral regurgitation (MR). However less is known about prognostic indicator for new-onset AF.
Purpose
The purpose of this study was to identify the prognostic relevance of exercise pulmonary hypertension for the new-onset AF in patients with primary MR.
Methods
Total of 114 consecutive patients with primary MR who underwent symptom-limited exercise echocardiography using supine-cycle ergometer were followed for new-onset AF over mean follow-up time of 3.6±2.6 years. Those with prevalent AF and pulmonary hypertension (estimated systolic pulmonary artery pressure ≥50mmHg) prior to exercise echocardiography were excluded from our analysis. We defined exercise-induced pulmonary hypertension (ExPHT) as those with peak estimated systolic pulmonary artery pressure (SPAP) ≥60mmHg or delta SPAP defined as differences between rest and peak SPAP ≥20mmHg.
Results
The mean age was 61±15 years old and 70 (61%) were male. Of those, 8 (7.8%) had mild MR, 32 (31.1%) had moderate MR, and 63 (61.2%) had severe MR. 60 (52.2%) patients had ExPHT. A total of 27 cases of new-onset AF were found during follow-up where the ExPHT group had higher prevalence of new-onset AF than the non-ExPHT group (35% vs. 11%, p=0.002). Those with ExPHT had significantly stronger association with shorter event-free survival time of new-onset AF (log-rank p<0.001, Figure). When adjusted for age, sex, body surface area, the American Society of Echocardiography MR grade, left atrial dimension, peak systolic blood pressure and heart rate, the multivariable Cox regression analysis showed that those with ExPHT had a hazard risk of 3.1 ([95% CI 1.1–9.1], p=0.039) for new-onset of AF.
Conclusions
Exercise-induced pulmonary hypertension predicted incident of new-onset AF in those with primary MR. Exercise echocardiography is expected to play an important role in decision making with regards to the optimal timing for surgical intervention in primary MR.

Abstract
Objectives:To assess the clinical implications of ultrasonography (US) in monitoring disease activity and diagnosis of relapsing polychondritis (RP).Methods:Firstly, auricular (n=5) and nasal (n=1) chondritis of six patients with RP were assessed by US before and after treatments. The relationship between US findings and serum markers were evaluated. Moreover, the comparisons of US findings between the auricle of patients with RP (n=5), repeated trauma (n=5), cellulitis (n=2) and healthy subjects (n=5) were also assessed.Results:US finding before treatment showed low-echoic swollen auricular and nasal cartilage with increased power Doppler signals (PDS) in all cases of RP. US findings corresponded to biopsy findings. After treatment, the swollen ear and nose completely resolved. Then, US findings also showed dramatic reductions in swollen cartilage with the decrease in PDS. Although serum markers completely improved, US finding remained in 1 of 6 cases, and this case showed flare due to PSL tapering. Finally, RP could be differentiated from the damage of repeated trauma and cellulitis by the presence or absence of PDS and subperichondrial serous effusion.Conclusion:US of auricular and nasal cartilage in RP possibly facilitates evaluation of auricular lesions and monitoring of disease activity, especially when we consider the treatment response and the timing of drug tapering.Disclosure of Interests:None declared

Abstract
Background:Adult-onset Still’s disease (AOSD), a systemic inflammatory disorder, is characterized by high fever, evanescent rash, arthritis, and hyperferritinaemia. AOSD is also reported to be associated with other skin lesions, including persistent pruritic papules and plaques.Objectives:This study aimed to assess the significance of dyskeratotic skin lesions in Japanese AOSD patients.Methods:We retrospectively assessed the histology of persistent pruritic skin lesions and evanescent rashes and the relationship between dyskeratotic cells, serum markers, and outcomes in 20 Japanese AOSD patients, comparing AOSD histology with that of dermatomyositis (DM), drug eruptions, and graft-versus-host disease (GVHD).Results:Persistent pruritic lesions were characterized by scattered single keratinocytes with an apoptotic appearance confined to the upper layer of the epidermis and horny layer without inflammatory infiltrate. In contrast to AOSD, the histology of DM, drug eruption, and GVHD demonstrated dyskeratotic cells in all layers of the epidermis with inflammatory infiltrate. AOSD with evanescent rash showed no dyskeratotic cells. The dyskeratotic cells in pruritic AOSD lesions stained positive for ssDNA and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling, indicating apoptosis. Serum IL-18 was significantly higher in AOSD patients with dyskeratotic cells than those without, and generally required higher doses of glucocorticoids, immunosuppressants, and biologic agents. Two of ten AOSD patients with dyskeratotic cells died from haemophagocytic lymphohistiocytosis.Conclusion:Persistent pruritic AOSD skin lesions are characterized by dyskeratotic cells with apoptotic features, involving the upper layers of the epidermis. There may be a link to elevated IL-18. This dyskeratosis may be a negative prognostic indicator.Disclosure of Interests:None declared

Abstract
Abstract
Background Five-year adjuvant treatment with aromatase inhibitors is a standard treatment for postmenopausal women with estrogen receptor-positive breast cancer. However, aromatase inhibitor-related adverse events, including joint and vasomotor symptoms, have a strong impact on patient quality of life and sometimes cause the discontinuation of treatment. The aim of this prospective cohort study based on patient-reported outcomes (PROs) was to examine the influence of adverse events on prognosis in Japanese postmenopausal patients with breast cancer treated with adjuvant anastrozole. Patients and Methods A total of 391 postmenopausal Japanese women with estrogen receptor-positive breast cancer who were treated with adjuvant anastrozole were enrolled from 28 centers in this prospective cohort study (SAVS-JP, UMIN000002455). PRO assessments of adverse events, which included joint and vasomotor symptoms, were obtained at baseline and 3, 6, 9, and 12 months. Symptoms were assessed and assigned to one of four categories: none (G0), mild (G1), moderate (G2), and severe (G3). The questionnaires covered joint symptoms (arthralgia, decrease in range of joint motion, and joint stiffness), vasomotor symptoms (hot flashes, night sweats, and cold sweats), and adherence to anastrozole. The median follow-up was 82 months, and we analyzed the prognosis in patients, focusing on the occurrence of joint and vasomotor symptoms induced by treatment. Results Of the 391 patients, 204 (52.2%) completed 5-year treatment, 75 (19.2%) discontinued (adverse events (n=35), recurrence (n=19), secondary malignancies (n=4), death from non-breast cancer (n=4), and other reasons (n=13)), 48 (12.3%) are receiving treatment, and 64 (16.4%) were unknown. Patients who experienced G2+3 joint symptoms had significantly better disease-free survival (DFS) compared with patients with G0+1 joint symptoms (5-year DFS, 96.1% vs. 83.3%, p=0.002). Similarly, the DFS in patients with G2+3 vasomotor symptoms was significantly better than that in those with G0+1 vasomotor symptoms (5-year DFS, 93.5% vs. 86.3%, p=0.049). Joint symptoms were marginally associated with overall survival (OS) (p=0.062), but no significant association was found with vasomotor symptoms. The DFS was superior in patients with G2+3 joint and vasomotor symptoms (5-year DFS, 100%), inferior in those with G0+1 joint and vasomotor symptoms (5-year DFS, 82.6%), and intermediate in others (5-year DFS, 93.3%; p=0.0024). By multivariable analysis including tumor size and grade, G2+3 joint symptoms were a significant and independent predictive factor for DFS (hazard ratio, 0.298, 95% confidence interval 0.122-0.621, p=0.0007). Conclusion Although adverse events might make patients uncomfortable and reduce their quality of life, it is suggested that worse or new vasomotor symptoms and severe joint symptoms, especially if they are grade 2 or 3, seem to associate with better prognosis.

Abstract
Abstract
Background
Grading the severity of aortic stenosis (AS) is challenging, since there is a discrepancy between aortic valve area (AVA) and mean pressure gradient (mPG). Arotic valve resistance (RES) has been proposed as a usuful descriptor of AS severity, but it is not commonly used for clinical decision-making, because its robust validation of clinical-outcome efficacy is lacking. This study aimed to investigate whether RES holds an incremental value for risk-stratifying AS.
Methods
This study recuited 565 AS patients (AVA < 1.5cm²) referred to echocardiography for valve assessment. The patients were divided into three different groups, according to the guidelines: high-gradient AS (HG-AS, mPG≥40mmHg, n = 157), low-gradient AS (LG-AS, mPG < 40mmHg + AVA ≤ 1.0cm², n = 155) and moderate AS (Mod-AS, mPG < 40mmHg + AVA > 1.0cm², n = 253). RES was calculated from Doppler measurement of mPG and stoke volume. The diagnositic cutoff point for RES was determined at 190 dynes × s×cm-5 by substituting AVA = 1.0cm² and mPG = 40mmHg into the definition formula of RES and Gorlin formula. The patients were followed up for 2 years. The endpoint was a composite of cardiac death, hospitalization for heart failure and aortic valve replacement necessitated by the development of AS-related symptoms.
Result
Kaplan-Meier analyses showed that LG-AS exhibited an intermediate outcome between HG-AS and Mod-AS (event-free survival at 2 years = 20.9% for HG-AS, 59.7% for LG-AS, 89.9% for Mod-AS, p < 0.001, figure A). When LG-AS was stratified by RES, the survival curves showed a significant separation (event-free survival at 2 years = 35.3% for high RES, 70.7% for low RES, p < 0.001, figure B). This trend persisted even when analysed separately for norml (stroke volume index > 35ml/m²) and low (stroke volume index ≤ 35ml/m²) flow state ((normal flow) event-free survival at 2 years = 38.7% for high RES, 70.4% for low RES, p = 0.023, figure C; (low flow) event-free survival at 2 years = 26.7% for high RES, 74.6% for low RES, p < 0.001, figure D).
Conclusion
This study confirmed the clinical efficacy of RES for risk-stratifying LG-AS patients.

Abstract
Transverse fractures of the spinous process of the 7th cervical vertebra were noted in 2 patients and of the 1st thoracic vertebra in 1 patient on maintenance hemodialysis. Two patients with aluminum (AI)- and/or iron-related bone disease complained of bone pain, relieved by deferoxamine therapy. In all three cases, the bone fractures had occurred suddenly while the patients were going about their daily work. These observations indicate that AI- or iron-related bone disease with secondary hyperparathyroidism can induce bone fracture by only slight stress in patients maintained on hemodialysis.

Abstract
Sea surface temperature (SST) fronts in mid- to high-latitude oceans have significant impacts on extratropical atmospheric circulations and climate. In the western subarctic Pacific, sharp SST fronts form between the cold subarctic water and the recently found quasi-stationary jets that advect warm waters originating in the Kuroshio northeastward. Here we present a new mechanism of the jet formation paying attention to the propagation of baroclinic Rossby waves that is deflected by eddy-driven barotropic flows over bottom rises, although their height is low (~500 m) compared with the depth of the North Pacific Ocean (~6000 m). Steered by the barotropic flows, Rossby waves bring a thicker upper layer from the subtropical gyre and a thinner upper layer from the subarctic gyre, thereby creating a thickness jump, hence a surface jet, where they converge. This study reveals an overlooked role of low-rise bottom topography in regulating SST anomalies in subpolar oceans. Sea surface temperature fronts in mid-and-high latitudes give significant impacts on atmospheric circulations and climate. Here, the authors uncover a new mechanism on the sea surface front genesis in the subpolar oceans in which small-amplitude bottom topography is surprisingly effective.

Abstract
We compared Wisteria floribunda agglutinin-positive Mac-2-binding protein (WFA+ -M2BP) levels between patients with chronic hepatitis B (n=249) and chronic hepatitis C (n=386) based on the degree of liver fibrosis. We examined WFA+ -M2BP levels in patients with F4 (cirrhosis), F3 or more (advanced fibrosis) and F2 or more (significant fibrosis) in the two groups. We further examined the relationship between five fibrosis markers and the degree of fibrosis. The WFA+ -M2BP values ranged from 0.25 cut-off index (COI) to 12.9 COI in patients with hepatitis B and 0.34-20.0 COI in patients with hepatitis C (P<.0001). The median WFA+ -M2BP values in F4 in the two groups were 2.83 COI in patients with hepatitis B and 5.03 COI in patients with hepatitis C (P=.0046). The median WFA+ -M2BP values in F3 or more in the two groups were 1.79 COI in patients with hepatitis B and 3.79 COI in patients with hepatitis C (P<.0001). The median WFA+ -M2BP values in F2 or more in the two groups were 1.49 COI in the hepatitis B cohort and 3.19 COI in the hepatitis C group (P<.0001). Among five liver fibrosis markers, WFA+ -M2BP had the highest correlation coefficient (rs =.629) in terms of correlation with the degree of fibrosis in the patients with hepatitis C and had the second highest rs value (.415) in the hepatitis B group. Although WFA+ -M2BP could be a useful indicator of liver fibrosis, WFA+ -M2BP levels in the two groups significantly differed even in the same degree of fibrosis. Individual cut-off values in each aetiology for the degree of fibrosis should be determined.

Abstract
The surgical treatment of defects caused by noma is challenging for the surgeon and the patient. Local flaps are preferred, but sometimes, because of the nature of the disease, there is not enough local tissue available. We describe our experience of free tissue transfer in Ethiopia. Between 2008 and 2014, 34 microsurgical procedures were done over 11 missions with the charity Facing Africa, predominantly for the treatment of defects caused by noma (n=32). The mean duration of operation was 442 minutes (range 200 - 720). Six minor wound infections were treated conservatively and did not affect outcome, a return to theatre was required in 4 patients with wound infections and one with a haemorrhage; 2 flaps failed and 2 partially failed, one patient developed an oronasal fistula, and one had an infection at the donor site that required a repeat graft. In settings where resources are limited, free flaps can be used when local tissue is not available and they cause less morbidity than pedicled tissue transfer.

Abstract
We describe a series of 8 patients who had total reconstruction of the nose during 4 separate missions to Ethiopia. The aetiology was noma (n=3), assault (n=2), acid burn (n=1), squamous cell carcinoma (n=1), and a sequela of meningococcal septicaemia (n=1). Reconstruction was with forehead flaps when adequate tissue was available (n=6) and with radial forearm flaps when it was not (n=2). Some reconstructive approaches require procedures to be done in stages, and in settings where resources are limited, difficulties with the continuity of care and provision for the management of complications, must be overcome.

Risk factors for joint symptoms in postmenopausal Japanese breast cancer patients treated with anastrozole: a prospective multicenter cohort study of patient-reported outcomes. Int J Clin Oncol 2015; 21:262-269.

Abstract
BACKGROUND Endocrine treatment-related adverse events have a strong impact on patients' quality of life and sometimes result in treatment discontinuation. Since joint symptoms are the most frequently recognized side effect of aromatase inhibitors, evaluation of associated risk factors may yield significant findings. PATIENTS AND METHODS A total of 391 postmenopausal Japanese women with estrogen receptor-positive breast cancer and treated with adjuvant anastrozole were enrolled from 28 centers for assessment of patient-reported outcomes (PROs) in this prospective cohort study (SAVS-JP, UMIN000002455). Patients completed the self-report questionnaire at baseline and after 3, 6, 9, and 12 months of treatment for evaluation of frequency of treatment-related joint symptoms (arthralgia, decrease in range of joint motion, and joint stiffness). RESULTS We obtained PROs from 362 patients (92.6 %) at baseline and at one or more subsequent points. New or worsening from baseline of joint symptoms were reported by 260 patients (71.8 %). More than 90 % of the symptoms were mild or moderate and nearly 80 % had occurred by 6 months. Multivariate analysis showed that a short time span after menopause [odds ratio (OR) 0.95, 95 % confidence interval (CI) 0.90-0.99; P = 0.02] and adjuvant chemotherapy (OR 2.29, 95 % CI 1.06-4.95; P = 0.03) were significant independent risk factors for joint symptoms. No significant relationships between body mass index (BMI) and joint symptoms were identified. Eighteen patients discontinued treatment during the 1st year and eight of them reported joint symptoms. CONCLUSION Taking into consideration that PROs may yield higher prevalence rates than physician ratings for symptoms published in pivotal clinical trials, we found that a short time span after menopause and use of adjuvant chemotherapy, but not high BMI, were significantly associated with joint symptoms. These findings might prove useful for counseling before initiating treatment with adjuvant aromatase inhibitors in postmenopausal Japanese women.

Abstract
We report the formation of a nonmagnetic band insulator at the isopolar interface between the antiferromagnetic Mott-Hubbard insulator LaTiO_{3} and the antiferromagnetic charge transfer insulator LaFeO_{3}. By density-functional theory calculations, we find that the formation of this interface state is driven by the combination of O band alignment and crystal field splitting energy of the t_{2g} and e_{g} bands. As a result of these two driving forces, the Fe 3d bands rearrange and electrons are transferred from Ti to Fe. This picture is supported by x-ray photoelectron spectroscopy, which confirms the rearrangement of the Fe 3d bands and reveals an unprecedented charge transfer up to 1.2±0.2 e^{-}/interface unit cell in our LaTiO_{3}/LaFeO_{3} heterostructures.

Biological activity of Helicobacter pylori components in mammalian cells: is it independent of proteinase-activated receptors?

Abstract
To clarify the relationship between Helicobacter pylori (H. pylori), a risk factor for gastritis, peptic ulcer and gastric cancer, and proteinase-activated receptors (PARs) that contribute to inflammatory responses, we determined and characterized the biological activity of H. pylori components in the mammalian cells that express PARs. The activity of H. pylori extracts was assessed in distinct cell lines with high expression of PAR1 (RGM1 cells), PAR2 (A549 cells), or PAR2 and PAR4 (HCT-15 cells). A PAR1-activating peptide (AP), but not H. pylori extracts, caused prostaglandin E₂ (PGE₂) release in RGM1 cells. On the other hand, H. pylori extracts produced release of PGE2 and interleukin-8 (IL-8) in A549 and HCT-15 cells, respectively, as a PAR2-AP did. The activity of H. pylori extracts in A549 cells was not affected by a proteinase inhibitor or exposure to boiling, but abolished by inhibitors of lipopolysaccharide (LPS), IRAK-1/4 or NF-κB. The activity of H. pylori extracts in HCT-15 cells was partially suppressed by boiling or the proteinase inhibitor. In rat platelets that express PAR4 and PAR3, like a PAR4-AP, H. pylori extracts induced aggregation when assessed in platelet rich plasma, an effect unaffected by the proteinase inhibitor, but did not cause aggregation of washed rat platelets that responded to the PAR4-AP or thrombin. The present study thus shows the biological activities of H. pylori extracts in A549 and HCT-15 cells or rat platelets, and suggests that they are not mediated by any PAR-activating proteinases, but may involve the other pathogenic factors including LPS.

Abstract
Several factors have been reported as risk factors for the development of osteoporosis. In this study, we aimed to examine the relationship among lifestyle factors, biologic factors, and bone mineral density (BMD) using structural equation modeling (SEM). The subjects in the present study consisted of 866 postmenopausal Japanese women aged between 40 and 80 years old. In the analysis by the SEM, we employed a multiple basic model. As the structural variables, lifestyle factors and biologic factors were selected.The goodness of fit index (GFI) of the final model was 0.991 and the Akaike's information criteria (AIC) showed the lowest value in the peripheral models. The degree of association between biologic factors and BMD was -0.576 (direct association), 0.012 (indirect association), and -0.564 (total association). With regard to the correlation between lifestyle factors and BMD, the degrees of association were 0.085, -0.084, and 0.001, respectively.This study defined a pilot model for factors influencing BMD. Although is remains necessary to conduct further analyses with more valid measurements and constructs, this model indicated that the correlation between BMD and lifestyle factors was lower than that between BMD and biologic factors.

Abstract
PURPOSE OF INVESTIGATION To assess the clinical relevance of serum growth-regulated oncogene alpha (GROalpha) levels in gynecological cancer, we investigated its concentration in distinguishing patients with cervical cancer, endometrial cancer, ovarian cancer, benign ovarian tumor and control. METHODS Preoperative serum GROalpha levels were measured in women with cervical cancer (n=46), endometrial cancer (n=39), ovarian cancer (n=124), benign ovarian tumors (n=52), and normal controls (n=38) using an enzyme-linked immunosorbent assay. RESULTS Statistical analyses showed that the serum GROalpha concentration was significantly elevated in the cervical cancer, endometrial cancer and ovarian cancer patients compared with controls. Using GROalpha levels, the receiver operating characteristic (ROC) of cervical cancer (AUC approximately 0.775), endometrial cancer (AUC approximately 0.799), ovarian cancer (AUC approximately 0.749) and benign ovarian tumors (AUC approximately 0.568) vs. controls were identified. CONCLUSION Our findings suggest that serum GROalpha measurement as a molecular marker might contribute to detection and diagnosis of gynecological cancer.

Abstract
Despite its potential for use in large-scale analyses, previous attempts to utilise administrative data to identify healthcare-associated infections (HAI) have been shown to be unsuccessful. In this study, we validate the accuracy of a novel method of HAI identification based on antibiotic utilisation patterns derived from administrative data. We contemporaneously and independently identified HAIs using both chart review analysis and our method from four Japanese hospitals (N=584). The accuracy of our method was quantified using sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) relative to chart review analysis. We also analysed the inter-rater agreement between both identification methods using Cohen's kappa coefficient. Our method showed a sensitivity of 0.93 (95% CI: 0.87-0.96), specificity of 0.91 (0.89-0.94), PPV of 0.75 (0.68-0.81) and NPV of 0.98 (0.96-0.99). A kappa coefficient of 0.78 indicated a relatively high level of agreement between the two methods. Our results show that our method has sufficient validity for identification of HAIs in large groups of patients, though the relatively lower PPV may imply limited utilisation in the pinpointing of individual infections. Our method may have applications in large-scale HAI identification, risk-adjusted multicentre studies involving cost of illness, or even as the starting point of future cost-effectiveness analyses of HAI control measures.

Abstract
Metastasis of malignant tumors to the oral cavity is rare. The authors report a case of thyroid carcinoma with mandibular osteoblastic metastasis. An 83-year-old female presented with lower jaw swelling and pain. An elastic hard subcutaneous mass was observed in the median mandible. X-ray images confirmed a tumor lesion with periosteal reaction spreading radially from the mandible. A biopsy revealed nests of large, polygonal tumor cells growing in a supporting fibrovascular framework. The patient's anamnesis included thyroid carcinoma with lung metastasis, 2 years ago, treated by total enucleation of the thyroid and excision of the superior lobe of the left lung. Biopsy, primary and metastatic tumor samples all tested positive for thyroglobulin, suggesting a thyroid follicular epithelial origin. Mandibular metastasis of poorly differentiated carcinoma of the thyroid gland was diagnosed. Consent for further treatment was not obtained. The patient died 1 year and 7 months later.

Abstract
A 77-year-old female with abdominal pain and ascites was admitted to our hospital. She had a past history of the postoperative pelvic irradiation for uterine cancer and subsequently suffered from neurogenic bladder. On admission, serum creatinine (s-Cr) and blood urea nitrogen (BUN) were elevated to 9.9 mg/dl and 131 mg/dl, respectively. However, both the ratio of BUN/s-Cr and creatinine in ascites/s-Cr were significantly elevated. The clinical manifestations of the present case were not typical for acute kidney injury. Furthermore, 2 days after urethral catheterization, both s-Cr and BUN were normalized (0.69 mg/dl and 10 mg/dl, respectively) and her symptoms had improved immediately. Therefore, we diagnosed her disease as spontaneous bladder rupture. We report a case with spontaneous bladder rupture mimicking acute kidney injury forty years after postoperative pelvic irradiation for uterine cancer.
