Abstract
Abstract
Background
Clinical congestion is the most dominant feature in patients with acute decompensated heart failure (HF). However, uncertainty exists due to the permutations and combinations of congestion status and decongestion strategies. We aimed to investigate the impact of congestion status and its improvement on 1-year mortality.
Methods
We prospectively included 453 consecutive patients hospitalized for acute decompensated HF between July 2015 and March 2017. Congestion was evaluated using the congestion score which consists of signs and symptoms including dyspnea, fatigue, orthopnea, jugular vein distension, rales, and edema. This score ranges from 0 to 3 for each value, and calculated by summing each score. We assessed this score at admission, day 3, and discharge.
Results
The median age was 81 (interquartile range 75–87) years, and 54.1% of the subjects were male. The 1-year mortality rate was 22.7%. The congestion scores at admission, day 3, and discharge were 10.7±3.9, 3.4±3.5, and 0.3±0.8, respectively. The rate of improvement during the first 3 days was 78% and 46.6% had residual congestion, defined as scores at day 3 ≥3. The score at day 3 and improvement rate during the first 3 days were related to 1-year all-cause mortality (P<0.001). We examined combined predictive values by calculating multivariable-adjusted hazard ratios for associations of residual congestion and improvement rate during the first 3 days (cut-off value 64%); and prognostic variables identified by univariate Cox regression model (age, body mass index, systolic blood pressure, potassium level, albumin level, the prevalence of anemia and hypertension, left ventricular ejection fraction, ischemic etiology, previous HF hospitalization). Residual congestion and lesser improvement (% improvement <64%) were associated with higher relative risk of 1-year all-cause mortality than residual congestion and higher improvement (% improvement ≥64%) [adjusted hazard ratio (aHR) 2.33, 95% CI 1.11–4.91, P=0.025], or resolved congestion (aHR 2.17, 95% CI 1.30–3.63, P=0.003). Similar analysis revealed significant relationship of the score at day 3 and the rate of improvement from admission to day 3 to cardiovascular mortality. Combined predictive values of residual congestion and lesser improvement with adjustment for prognostic variables identified by univariate Cox regression model (age, body mass index, systolic blood pressure, potassium level, albumin level, the prevalence of anemia, reduced eGFR, and hypertension, left ventricular ejection fraction, ischemic etiology, previous HF hospitalization) were higher than those with residual congestion and higher improvement (aHR 3.04, 95% CI 1.15–8.03, P=0.025), or resolved congestion (aHR 3.17, 95% CI 1.65–6.11, P<0.001).
Conclusions
This study suggested that rapid decongestion therapy after hospital admission could be prerequisite to improve 1-year mortality in acute decompensated HF.

Abstract
Abstract
Background
Along with an aging society, the global burden of heart failure (HF) is evident in Japan. Recent reports showed that malnutrition is one of the frequent comorbidity in patients with HF, and this grievous issue is related to worsening prognosis in such subjects. There are many screening tools of nutrition risks, however, feasible indexes or strategies for evaluating nutrition risk in patients with HF remain to be identified definitively.
Purpose
The purpose of the present study was to examine the effectiveness of various nutrition indexes on 3-year mortality in hospitalized acute HF patients.
Methods
The study population comprised a total of 817 individuals who were hospitalized for acute HF between November 2009 and December 2015, and was followed up for 3 years. All the previously established objective nutritional indexes [The controlling nutritional status (CONUT) score, geriatric nutritional risk index (GNRI), and subjective global assessment (SGA)] were evaluated at the time of hospital admission. Malnutrition status of each index was defined as CONUT score ≥5, GNRI <91, or SGA (B and C), respectively. We evaluated combined predictive values of these indexes for 3-year mortality by Cox regression model, and calculated the net reclassification improvement (NRI) and the integrated discrimination improvement (IDI).
Results
The median age was 79 (interquartile range 70–85) years, and 55.7% of the subjects were male. The frequency of malnutrition was 18.1% in CONUT score, 31.9% in GNRI, and 25.9% in SGA. The rate of 3-year mortality was 32.2%. All indexes were related to the occurrence of 3-year mortality by univariate analyses (P<0.001). We examined combined predictive values by calculating multivariable-adjusted hazard ratios (aHR) and 95% confidence intervals (CI) for associations of malnutrition by these 3 indexes and prognostic variables identified by multivariable Cox regression model (age, body mass index, systolic blood pressure, reduced eGFR, albumin, and prior HF hospitalization). Malnutrition of all 3 indexes (5.6% of the subjects) was associated with higher relative risk of 3-year mortality than well-nutrition (aHR 1.90; 95% CI 1.07–3.35, P=0.028), or malnutrition of any 1 index (aHR 1.95; 95% CI 1.18–3.21, P=0.009). Next, we individually included each value into a reference model (age, body mass index, reduced eGFR, albumin, prior HF hospitalization, and ischemic etiology by multivariable logistic regression analysis with P<0.05). SGA was superior according to comprehensive discrimination, calibration, and reclassification analysis (NRI 0.212, P=0.003; IDI 0.005, P=0.029). Similar analysis with other indexes (CONUT score or GNRI) revealed no improvement.
Conclusion
Our present results suggest that simultaneous addition of CONUT, GNRI, and SGA seems useful for predicting long-term mortality in acute HF. In addition, nutritional screening with SGA independently improves mortality risk stratification.

Abstract
Abstract
Background
Renal dysfunction is associated with poor mortality in patients with heart failure (HF). Hepatic dysfunction, assessed by Fibrosis-4 (FIB4) index, has also prediction ability in acute decompensated HF (ADHF) patients. We investigated whether the assessment of the combination of FIB4 index and renal dysfunction improves predictability in patients with ADHF.
Methods
We retrospectively enrolled consecutive 758 patients who admitted due to ADHF from January 2011 to February 2018 and followed up for one year. FIB4 index on admission was calculated by the formula: age (yrs) × AST[U/L] / (platelets [103/μL] × (ALT[U/L])1/2). Study subjects were divided into high FIB4 index (>3.25) and low FIB4 index (≤3.25), furthermore each group were classified by the presence/absence of CKD (estimated glomerular filtration rate <60 ml/min/1.73m). We have generated four groups; low FIB4/without CKD (n=154), low FIB4/with CKD (n=294), high FIB4/without CKD (n=56), and high FIB4/with CKD (n=254). The primary outcome was defined as all-cause mortality in one year. We performed Kaplan-Meyer analysis and multivariable Cox regression models. Furthermore, we evaluated the incremental value with C-index, net reclassification improvement (NRI) and integrated discrimination improvement (IDI) when FIB4 index and renal dysfunction added to a baseline model.
Results
In total, 106 patients died in one year. High FIB4 index and CKD showed significantly higher 1-year mortality (high FIB4 index: 19.7% vs 10.3%, p<0.001, CKD: 17.0% vs 6.7%, p<0.001, respectively). Kaplan-Meyer analysis shows that high FIB4 index with CKD showed statistically higher mortality than the others (vs low FIB4/without CKD, p<0.001, vs high FIB4/without CKD, p=0.031, vs low FIB4/with CKD, p<0.001, respectively).
Multivariate Cox regression model revealed that both high FIB4 index and CKD were an independent risk predictor of 1-year mortality (FIB4 index: p<0.001, HR 1.06, 95% CI 1.035–1.087, CKD: p=0.004, HR 1.834, 95% CI 1.213–2.773, respectively) in patients with ADHF.
A baseline model for prediction of 1-year mortality was determined by multivariable logistic regression including age, body mass index, systolic blood pressure, and serum albumin (C-index: 0.688). Adding high FIB4 index and CKD to the baseline model, all of C-index (0.738, p=0.04), NRI (0.122, p=0.067), and IDI (0.024, p=0.004) were improved.
Receiver operating characteristic curves
Conclusions
Combination assessment of renal and hepatic dysfunction could improve the predictability of prognosis in patients with ADHF.

Abstract
Abstract
Background
The prognosis of heart failure remains poor similar to the terminal cancer patients, although recent progress in medical treatment. Palliative Prognostic Index (PPI) is a widely used prognostic index for terminal cancer patients (PPI includes: Palliative Performance Scale, oral intake, oedema, dyspnea at rest and delirium), suggesting the short-term prognostic marker of terminal cancer patients.
Purpose
The purpose of this study was to evaluate the impact of PPI on 30-day mortality, 1-year mortality and 1-year events (including all-cause mortality, readmission due to heart failure and new onset of cerebral infarction after hospital discharge) among acute decompensated heart failure (ADHF) patients.
Method
Study subjects comprised of consecutive 764 patients who admitted due to ADHF and followed up for 1-year. PPI were calculated at the time of hospital admission. Study subjects were divided into two groups based on the PPI: L-PPI (PPI<6) and H-PPI (6≤PPI). We calculated the C-index, net reclassification improvement (NRI) and the integrated discrimination improvement (IDI) to evaluate the improvement of prediction ability on 30-day mortality.
Result
H-PPI showed significantly higher 30-day mortality than L-PPI [7.9% vs 2.0%, log rank p<0.001, Hazard retio (HR): 1.26, 95% confidential interval(CI): 1.14–1.37, p<0.001], 1-year mortality [20.0% vs 12.7%, log rank p=0.022, HR 1.15, 95% CI 1.09–1.21, p<0.001]and 1-year events [45.5% vs 31.1%, log rank p<0.001, HR 1.13, 95% CI 1.09–1.17, p<0.001]. Multivariate cox proportional hazard models adjusted with several covariates revealed that PPI was an independent predictor of 30-day mortality (HR: 1.23, 95% CI: 1.10–1.36, p<0.001), 1-year mortality (HR: 1.10, 95% CI: 1.04–1.16, p<0.001) and 1-year events (HR: 1.11, 95% CI: 1.07–1.15, p<0.001), respectively.
A reference model for prediction of 30-day mortality was determined including left ventricular ejection fraction and serum albumin concentration by multivariable logistic regression analysis. (P<0.05) (C-index: 0.720) Adding PPI to the reference model (C-index: 0.773) significantly improved both NRI (0.458, p=0.038) and IDI (0.046, p=0.007), respectively.
Conclusion
We suggest that assessment of PPI showed good prognostic ability for 30-day and 1-year outcome, while PPI provided additional prognostic information in patients with ADHF.

Abstract
Abstract
Background
Several studies have proved that both poor nutrition (PN) and Frail are associated with poor prognosis among heart failure patients. However, it has not been fully revealed whether PN and frail could have impact on prognosis accumulatively.
Purpose
The purpose of the present study was to evaluate the impact of nutritional and Frailty status on 1-year mortality among hospitalized patients with acute decompensated heart failure (ADHF).
Methods
Study subjects comprised of 315 hospitalized patients with ADHF. To evaluate the nutritional and Frailty status, we calculated the controlling nutritional status (CONUT) score and the Study of Osteoporotic Fractures (SOF) index at hospital admission. PN and Frailty were defined as the CONUT score ≥5 and SOF index ≥2, respectively.
Results
z Sixty-nine subjects (21.9%) were died within 1-year. PN and Frailty were observed in 33.3% and 55.6% of study subjects, respectively. Both PN and Frailty were similarly related to the 1-year mortality by univariate cox regression analysis (Hazard Ratio (HR) 2.43, 95% confidence interval (CI) 1.51–3.91, p=0.0003: HR 3.13, 95% CI 1.83–5.66, p<0.0001, respectively).
Study subjects were classified into 4 groups according to the nutritional and frailty status: control (normal nutrition without Frailty, n=110), PN alone (PN without Frailty, n=30), Frailty alone (Frailty without PN, n=100), and PN + Frailty (PN with Frailty, n=75). The Kaplan-Meier event curves for 1-year all-cause mortality illustrated that subjects with PN + Frailty had a significantly higher mortality than in subjects with control, PN alone and Frailty alone (log rank p=0.0001, 0.0180, 0.0070, respectively).
As well as, cox regression analysis revealed that PN + Frailty showed significantly higher mortality than control, PN alone and Frailty alone. (HR 5.33, 95% CI 2.75–11.1, p<0.0001: HR 2.99, 95% CI 1.26–8.78, p=0.011: HR 2.07, 95% CI 1.21–3.61, p=0.008, respectively). Moreover, multivariate cox regression analysis also revealed that PN with Frailty was independently associated with 1-year mortality even after adjustment for age, body mass index, systolic blood pressure, and chronic kidney disease. (HR 3.40, 95% CI 1.69–7.32, adjusted p<0.001)
Kaplan-Meier curve for 1year mortality
Conclusions
The combination assessment consisted with nutrition and frailty could identify poor prognosis patients with ADHF.

Abstract
Abstract
Background
Interventional cardiology is gaining greater popularity worldwide with each passing year. Reduction of exposure dose is a very imminent and an important issue in cardiology procedure. Although a newer radiation reduction technique, device and procedure are very valuable and expected, we should consider about therapy technique, radiation technique, devices, and the way to protection. Digital zoom digitally enlarges images in real time by up to 2.5-fold at lower doses than those used with traditional field of view changes. In our phantom examination the average dose reduction of digital zoom was 27%.
Methods and results
This study is designated as single-center, retrospective, not-randomized, observation study. 2101 eligible cases were collected. We assigned the cases of PCI without the use of Digital zoom to the Conventional group and those involving the use of Digital zoom to the Digital zoom group. There were 806 patients in the Conventional group and 1195 in the Digital zoom group. Because we had begun using Digital zoom from January 2015 onwards, all patients in the Conventional group had undergone PCI from January 2013 to December 2014 and all patients in the Digital zoom group had undergone PCI from January 2015 to December 2016. In addition, we calculated the RAK/minute and DAP/minute for an accurate assessment. To minimize the difference of characteristics between two groups, propensity score including all baseline variables was performed. Furthermore, Predictors of radiation exposure were investigated using multivariable least square methods. Inter group differences were observed in DAP, RAK, DAP/min, and RAK/min (Digital zoom group vs conventional group: DAP, 16000 cGy cm2 [from 1st quartile to 3rd quartile; 10300–24400] vs 20700 [13400–29500], p<0.001; DAP/min, 557 cGy cm2/min [392–737] vs 782 [571–1010], p<0.01; RAK, 1590 Gy [990–2410] vs 1850 [1220–2720], p<0.01; RAK/min, 54.7 Gy/min [38.5–73.2] vs 71.2 [51.5–93.0], p<0.01). Even after propensity score matching, intergroup differences in DAP (810 cases), DAP/min (811 cases), RAK (746 cases), and RAK/min (744 cases) persisted. Furthermore, the least squares method showed that Digital zoom is an important predictor of DAP (β=0.17, p<0.01) and RAK (β=0.12, p<0.01).
Conclusion
Digital zoom is an old and cost-free technique, but one of most powerful reduction of exposure method. Propensity score adjustment and least square methods show that digital zoom is one of independent effective method.

Abstract
The aim of this study was to investigate the probability of facial nerve injury (FNI) in the treatment of condylar neck and subcondylar fractures (CN/SCFs) with percutaneous approaches and to identify factors predicting FNI. The data of 80 patients with 87 CN/SCFs were evaluated retrospectively. The primary outcome was FNI occurrence. The predictor variables were age, sex, aetiology, alcohol consumption, fracture site and pattern (dislocation or not), concomitant fractures, time interval to surgery, surgeon experience, plate type, and the dual classification of percutaneous approaches. The approaches were classified based on whether subcutaneous dissection traversed the marginal mandibular branch (MMB) deeply (deep group: submandibular and retroparotid approaches) or superficially (superficial group: transparotid, transmasseteric anteroparotid (TMAP), and high cervical-TMAP approaches). Twenty-two patients (27.5%) suffered FNI, of whom two in the deep group had permanent paralysis of the MMB. In the multivariate logistic regression model, deeply traversing surgery approaches (odds ratio 12.4, P=0.025) and the presence of a dislocated fracture (odds ratio 6.66, P=0.012) were associated with an increased risk of FNI. These results suggest that percutaneous approaches in the superficial group should be recommended for the treatment of CN/SCFs to reduce the risk of FNI.

Abstract
BACKGROUND No potential tumour markers have been validated for prognosis in endometrial cancer. However, carcinoembryonic antigen (cea) is one of the most widely used tumour markers in various types of cancer. Although cea expression in endometrial cancer has been investigated, its prognostic value remains controversial, and no studies have investigated serum cea levels in large case series. In the present study, we investigated diagnostic and prognostic applications of serum cea for endometrial cancer. METHODS This prospective study was approved by our Institutional Review Board. Between January 2006 and December 2012, serum cea was measured prospectively in 215 patients with endometrial cancer and was subsequently measured during treatment and at scheduled follow-up examinations in patients with elevated baseline serum cea. RESULTS During the study period, 215 patients (142 stage i, 19 stage ii, 32 stage iii, 22 stage iv) were treated for endometrial cancer. By the time of last follow-up, 52 had relapsed (24.2%), and the median follow-up duration was 45 months (range: 1-95 months). Elevated serum cea was identified in 25 patients (11.6%) and was associated with histologic type (p = 0.04), histologic grade (p = 0.03), and myometrial invasion depth (p = 0.01). Elevated serum cea was not related to clinical stage, lymph node metastasis, distant metastasis, age, menopausal status, or body mass index. Relapse of disease was related to elevated serum cea (p = 0.006). CONCLUSIONS Serum cea is a potential prognostic indicator for endometrial cancer.

Abstract
We present a statistical analysis of the first four seasons from a "second-generation" microlensing survey for extrasolar planets, consisting of near-continuous time coverage of 8 deg2 of the Galactic bulge by the OGLE, MOA, and Wise microlensing surveys. During this period, 224 microlensing events were observed by all three groups. Over 12% of the events showed a deviation from single-lens microlensing, and for ~1/3 of those the anomaly is likely caused by a planetary companion. For each of the 224 events we have performed numerical ray-tracing simulations to calculate the detection efficiency of possible companions as a function of companion-to-host mass ratio and separation. Accounting for the detection efficiency, we find that 55 - 22 + 34 % of microlensed stars host a snowline planet. Moreover, we find that Neptunes-mass planets are ~ 10 times more common than Jupiter-mass planets. The companion-to-host mass ratio distribution shows a deficit at q ~ 10-2, separating the distribution into two companion populations, analogous to the stellar-companion and planet populations, seen in radial-velocity surveys around solar-like stars. Our survey, however, which probes mainly lower-mass stars, suggests a minimum in the distribution in the super-Jupiter mass range, and a relatively high occurrence of brown-dwarf companions.

Abstract
BACKGROUND Krukenberg tumors mostly occur after 40 years. Metastatic ovarian tumors in young age are very rare. CASE A 18-year-old female presented with colon cancer which was accompanied by Krukenberg tumor. The present case was a very rare case of metastatic ovarian tumor in very young age. The present patient presented with abdominal pain. On examination, colon tumor was detected and bilateral ovary were almost normal with only slight swelling. During the operation for colon tumor, biopsy of bilateral ovary was performed for histopathological evaluation. Although there were no specific findings in bilateral ovary, microscopic examination revealed poorly differentiated adenocarcinoma, diffusely invading the ovarian parenchyma. Diagnosis of colon cancer was made postoperatively and ovarian Krukenberg tumor was confirmed. CONCLUSION In case of suspecting colon cancer even in very young patient with normal ovary, biopsy of ovary should be considered for the diagnosis of Krukenberg tumor.

Abstract
Nongestational choriocarcinoma is very rare and carries a poor prognosis in female patients. In this report, the authors present a case of nongestational choriocarcinoma with brain metastasis in a female. A 58-year-old female with intermittent back pain was referred to a private hospital. On examination, a mediastinal tumor and a pancreatic tumor were detected. Endoscopic ultrasound-guided fine needle aspiration biopsy of the tumor was performed for histological evaluation. Pathological diagnosis was difficult because only a small amount of tissue was collected. Head MRI showed multiple metastatic tumors in the brain. The patient was diagnosed with primary mediastinal choriocarcinoma with brain metastasis. She was treated with one course of an etoposide, methotrexate, dactinomycin, cyclophosphamide, and vincristine regimen, but her general condition gradually deteriorated, and she died on day 41. Nongestational choriocarcinoma is drug resistant, whereas gestational choriocarcinoma has better chemotherapeutic sensitivity.

Abstract
BACKGROUND Anti-N-methyl D-aspartate (anti-NMDA) receptor encephalitis is often accompanied by ovarian teratoma. Early tumor resection is reported to be effective as a treatment. CASE A 21-year-old woman presented with anti-NMDA receptor encephalitis which was accompanied by ovarian teratoma. The present case was a very rare case of an early stage of anti-NMDA receptor encephalitis receiving operative treatment before confirming the presence of anti-NMDA receptor antibody. The diagnosis was established postoperatively by identifying anti-NMDA receptor antibody. CONCLUSION In case of suspecting anti-NMDA receptor encephalitis in a patient with ovarian teratoma, early operative treatment should be considered even before confirming the presence of anti-NMDA receptor antibody.

Abstract
PURPOSE OF INVESTIGATION Primary peritoneal carcinoma (PPC) is histologically similar to ovarian serous carcinoma, but its biochemical features remain obscure. The authors investigated and compared clinical findings, treatments, and outcomes of patients with PPS and those with epithelial ovarian cancer (EOC) patients. MATERIALS AND METHODS The authors retrospectively reviewed data from 14 patients with PPC and 219 patients with EOC treated at the present hospital from January 2005 to December 2012, including demographic data, pathologic findings, treatments, and outcomes. RESULTS Patients with PPC were significantly older (62.6 ± 8.4 years) than those with EOC (56.3 ± 11.3 years) (p = 0.045). There was no significant difference in serum CA-125 levels. The five-year survival rates did not differ significantly between patients with PPC (61.1%) and those with EOC (60.3%; p = 0.78); nor between patients with PPC and those with Stage III serous EOC (43.8%; p = 0.40). CONCLUSIONS Treatment strategies for EOC applied to PPC apparently led to similar survival patterns among the two patient groups. Cytoreductive surgery combined with pre/postoperative platinum-containing chemotherapy may be effective for PPC patients.

Abstract
OBJECTIVES Chemotherapy-induced thrombocytopenia seems to be a relevant problem and the risk or clinical bleeding in patients wim gynecologic malignancy is reported to be higher than other malignancy. In this study, the authors investigated chemotherapy-induced thrombocytopenia recently performed in all patients with gynecologic malignancy. MATERIALS AND METHODS Between January 2009 and December 2011, the authors examined reported chemotherapy-induced thrombocytopenia using the Common Terminology Criteria for Adverse Events (CTCAE) v.4.0. They analyzed the incidence and clinical features of chemotherapy-induced thrombocytopenia in patients with gynecologic malignancy. RESULTS During this period they administered over 1,614 infusions (29 regimens) to 291 patients. Chemotherapy-induced thrombocytopenia occurred in 43 (14.8%) patients over 56 (3.5%) chemotherapy cycles. Bleeding occurred in 13 (4.5%) patients over 14 (0.9%) cycles. Platelet transfusions were administered for eight (2.7%) patients over eight (0.5%) cycles. Median platelet count at platelet transfusions was 17,000 /μl. Chemotherapy-induced thrombocytopenia was associated with more than five previous chemotherapy cycles, previous radiotherapy, disseminated disease, distant metastatic disease, poor performance status, and taxane-including regimens. Clinical bleeding was associated with previous radiotherapy, distant metastatic disease, poor performance status, and taxane-including regimens. CONCLUSIONS Estimating bleeding risk factor such as previous radiotherapy, distant metastatic disease, poor performance status, and taxane-including regimens seem to be important for safe management of chemotherapy-induced thrombocytopenia.

Abstract
Using gravitational microlensing, we detected a cold terrestrial planet orbiting one member of a binary star system. The planet has low mass (twice Earth's) and lies projected at ~0.8 astronomical units (AU) from its host star, about the distance between Earth and the Sun. However, the planet's temperature is much lower, <60 Kelvin, because the host star is only 0.10 to 0.15 solar masses and therefore more than 400 times less luminous than the Sun. The host itself orbits a slightly more massive companion with projected separation of 10 to 15 AU. This detection is consistent with such systems being very common. Straightforward modification of current microlensing search strategies could increase sensitivity to planets in binary systems. With more detections, such binary-star planetary systems could constrain models of planet formation and evolution.

Abstract
BACKGROUND Malignant melanoma is an extremely malignant tumor with an unpredictable metastatic profile with variable periods of remission. CASE A 41-year-old woman presented with recurrent malignant melanoma which had clinical features of an acute state mimicking primary peritoneal cancer. The case was an unusual recurrence of malignant melanoma occurring seven years after diagnosis and treatment of malignant melanoma in the patient's arm. The diagnosis was established postoperatively by immunohistochemistry. CONCLUSION A variety of imaging methods and pathological methods, including an exploratory laparotomy, may be necessary in cases of patients suspecting primary peritoneal cancer with a previous history of melanoma with possible metastatic dissemination. Urgent diagnosis and treatment of these patients seems to be critical.

Abstract
PURPOSE Sjögren's syndrome (SS) is an auto-immune disease presenting with dry eyes and mouth (keratoconjunctivitis sicca and xerostomia). Ultrasonography is used for the initial and non-invasive investigation of the parotid gland in the disease. The purpose of this study is to develop an image processing for diagnosis of SS by applying wavelet analysis to ultrasound image. METHODS Ultrasound B-mode images of the parotid gland were captured and analyzed by a personal computer. A square region of interest (ROI) was set on the image and two-dimensional discrete wavelet transform was performed within the ROI. As a Result, the image was decomposed into an approximate image and three detailed images in vertical, horizontal and diagonal directions in different scales. A feature quantity for image classification was defined by calculating from the wavelet coefficients of detailed images within selected scales. The ultrasound images of 80 patients who had been referred to Nagasaki University Hospital because of suspicion of SS were analyzed. A total of 37 patients fulfilled the criteria for SS, whereas the remaining 43 patients did not. The severity of SS was graded into four degrees by sialography. The images with each feature quantity were classified by statistical cluster analysis. RESULTS In this method, the images can be divided into two groups which mainly contained SS and non-SS. The sensitivity and specificity in the detection of SS was 78% and 95%, respectively. It was also found that the defined feature quantity tended to change with the severity of SS. CONCLUSIONS In ultrasonography, the image analysis based on wavelet transform was useful for the diagnosis of Sjögren's syndrome.

Abstract
BACKGROUND AND PURPOSE ADCs may help distinguish benign from malignant head and neck diseases. We sought to evaluate the effectiveness of ADC for differentiating between carcinomas and lymphomas of the nasopharynx and oropharynx. MATERIALS AND METHODS We retrospectively compared the ADCs between 24 histologically proved lymphomas and 32 carcinomas, including 8 NPCs and 7 lymphomas of the nasopharynx, and 24 SCCs and 17 lymphomas of the oropharynx. ADCs were determined on tumor-by-tumor (overall ADCs) and pixel-by-pixel (ADC mapping) bases by using 2 b-values (500 and 1000 s/mm(2)). RESULTS Lymphomas and oropharyngeal SCCs had unique histologic features in terms of keratinization, cell attenuation, stromal areas, and necrosis and had distinctive ADCs (0.503 ± 0.099 × 10(-3) mm(2)/s for lymphomas and 0.842 ± 0.164 × 10(-3) mm(2)/s for SCCs). However, NPCs and lymphomas were similar in terms of these histologic features, exhibiting comparable ADCs (0.567 ± 0.057 × 10(-3) mm(2)/s for NPCs and 0.528 ± 0.094 × 10(-3) mm(2)/s for lymphomas). Poorly and moderately differentiated SCCs with homogeneous T2 signals were indistinguishable from lymphomas on conventional MR images; however, ADCs of these SCC subtypes were significantly larger than those of lymphomas. ADC mapping profiles with respect to percentage of tumor areas of extremely low, intermediate, and high ADC levels were well-correlated with the histologic features of lymphomas, NPCs, and different types of SCCs. CONCLUSIONS The effectiveness of ADC-based differentiation between lymphomas and carcinomas of the nasopharynx and oropharynx depends on their histologic characteristics.

Abstract
PURPOSE OF INVESTIGATION Chemotherapy-related hypersensitivity reaction seems to be problematic in the safe management of chemotherapy. In this study we investigated chemotherapy-related hypersensitivity reaction in patients with gynecologic malignancy. METHODS Between January 2009 and December 2010, we examined hypersensitivity reaction (> or = grade2) using the Common Terminology Criteria for Adverse Events (CTCAE) v.4.0. We analyzed the incidence, clinical features, management, and outcome. RESULTS We administered over 1,057 infusions (24 regimens) to 205 patients. We found a total of four hypersensitivity reactions (> or = grade 2) cases (carboplatin: 2; nedaplatin: 1; docetaxel: 1). Signs and symptoms were varied. In two cases, the same regimen was rechallenged by using anti-allergic drugs. The docetaxel case was successful. The carboplatin case was not successful. CONCLUSION Chemotherapy-related hypersensitivity reaction (> or = grade2) does not occur frequently. In the case of platinum, especially, carboplatin, re-administering after hypersensitivity reaction should be done carefully though platinum is a key drug in patients with gynecologic malignancies.

Abstract
BACKGROUND AND PURPOSE The sinonasal region is a platform for a broad spectrum of benign and malignant diseases, and image-based differentiation between benign and malignant diseases in this area is often difficult. Here, we evaluated multiparametric MR imaging with combined use of TICs and ADCs for the differentiation between benign and malignant sinonasal tumors and tumorlike diseases. MATERIALS AND METHODS TICs obtained from dynamic contrast-enhanced MR imaging and ADCs were analyzed on a lesion-by-lesion (overall TIC and ADC) and pixel-by-pixel (TIC and ADC mapping) basis in patients with benign (n = 21) or malignant (n = 23) sinonasal tumors and tumorlike diseases. The TICs were semiautomatically classified into 5 distinctive patterns (flat, slow uptake, rapid uptake with low washout ratio, rapid uptake with high washout ratio, and miscellaneous). ADCs were determined by using b-values of 500 and 1000 s/mm(2). RESULTS Malignant sinonasal tumors had small (<25%) areas of the type 1 flat TIC profile as determined by pixel-by-pixel TIC analysis and large (≥50%) areas of low or extremely low ADCs (≤1.2 × 10(-3) mm(2/)s) as determined by ADC mapping. Consequently, stepwise classification on the basis of TICs and ADCs successfully (at 100% accuracy) discriminated malignant from benign sinonasal diseases in the present patient cohort. CONCLUSIONS Multiparametric MR imaging by using TICs and ADCs may help differentiate benign and malignant sinonasal diseases.

Abstract
BACKGROUND Conjunctival oedema is commonly observed in patients with allergic conjunctivitis and can be induced by histamine. In animal models of allergic conjunctivitis, conjunctival oedema is generally evaluated by measuring the extravasation of Evans blue dye into the conjunctiva. A limitation of this method is that it only allows evaluation at a single time point. The aim of the present study was to investigate kinetic changes in histamine-induced bulbar oedema. METHODS Evans blue dye was injected intravenously into male guinea pigs. Histamine eye-drops were administered 30 min later. One group of animals received levocabastine (an antihistamine) eye-drops 10 min before histamine challenge. A digital camera was used to obtain images of the bulbar conjunctiva at 1 min intervals until 30 min after histamine challenge. The conjunctivas were then harvested, and the concentration of Evans blue was measured. The ImageJ software was used to analyse the images by counting the number of absolute pixel values. RESULTS The degree of conjunctival oedema increased progressively until 20 min after histamine challenge and then stabilised. Correspondingly, the number of absolute pixel values increased significantly until 5 min after histamine challenge, then increased gradually until the 20 min time point and finally plateaued. Pixel values were significantly lower in animals treated with levocabastine than in control animals. A significant correlation was observed between the pixel values of the conjunctival images and the concentration of Evans blue in the conjunctiva. CONCLUSIONS This is the first study to have quantitatively evaluated kinetic changes in histamine-induced bulbar oedema by means of image analysis.

Abstract
BACKGROUND Plaque erosion is a cause of atherothrombosis that preferentially occurs on smooth muscle cell (SMC)- and proteoglycan-rich rather than lipid-rich plaques. However, its underlying mechanisms remain unknown. OBJECTIVE To determine whether disturbed blood flow induces erosive injury and thrombus formation on SMC-rich neointima. METHODS Three weeks after balloon injury, SMC-rich neointima with increased tissue factor (TF) activity developed in rabbit femoral arteries that were narrowed with a vascular occluder to disturb blood flow after stenosis. Neointimal injury and thrombus formation were assessed at 15, 30, and 180 min after the vascular narrowing. RESULTS Endothelial detachment, platelet adhesion and neointimal cell apoptosis became evident at the post-stenotic regions of all femoral arteries (n = 5) within 15 min of narrowing. Mural thrombi composed of platelet and fibrin developed after 30 min, and then occlusive thrombi were generated in three out of five vessels after 180 min. The identical vascular narrowing of normal femoral arteries also induced endothelial detachment with small platelet thrombi at post-stenotic regions, but fibrin and occlusive thrombi did not develop. Computational simulation analysis indicated that oscillatory shear stress contributes to the development of erosive damage to the neointima. CONCLUSIONS These results suggest that disturbed post-stenotic blood flow can induce erosive injury in SMC-rich plaques and promote thrombus formation that results in vascular events.

Abstract
Paclitaxel and carboplatin combination chemotherapy (TC) is increasingly performed in ovarian cancer patients undergoing hemodialysis. However, appropriate dosage and time interval between the end of carboplatin administration and the initiation of hemodialysis remain unclear. We performed TC in a hemodialysis patient with ovarian cancer. Paclitaxel was administered at 150 mg/m2 for 3 h, followed by administration of 125 mg of carboplatin within 30 min to achieve a target area under the concentration/time curve (AUC) of 5.0 mg/ml x min by Calvert's formula. At 1 h after completing carboplatin administration, hemodialysis was performed for 4 h. Pharmacokinetic analysis showed we had achieved the desired serum concentration of paclitaxel. However, AUC of free platinum was very low (AUC = 0.98 mg/ml x min). Although the appropriate time interval between the end of carboplatin administration and the initiation of hemodialysis remains a controversial issue, our findings suggest that an interval of at least 1 h is required.

Abstract
BACKGROUND/AIMS Tumour-necrosis-factor-related apoptosis-inducing ligand (TRAIL) plays a role in the development of allergic asthma. The study aimed to determine whether TRAIL also participates in the development of experimental allergic conjunctivitis (EC), another allergic disease model. METHODS EC was induced in BALB/c mice by active immunisation with ragweed (RW) followed by RW challenge. To investigate whether TRAIL in the conjunctiva plays a role in the development of EC, conjunctival TRAIL expression in EC-developing mice was evaluated by immunohistochemistry. Additionally, the effect of subconjunctival injection of recombinant TRAIL on conjunctival inflammation was examined. To investigate whether TRAIL expressed in systemic immunocompetent cells plays a role in the development of EC, anti-TRAIL blocking Ab or anti-TRAIL receptor agonistic Ab was intraperitoneally injected into EC-developing mice, and conjunctival eosinophil infiltration was evaluated. RESULTS Conjunctival TRAIL expression was not increased by EC induction. Moreover, subconjunctival injection of TRAIL protein in naive mice did not induce conjunctival inflammation. Thus, TRAIL in the conjunctiva is less likely to participate in the development of EC. Systemic treatment with anti-TRAIL blocking Ab in EC-developing mice did not affect the severity of EC. However, systemic treatment during the induction phase of EC with an agonistic Ab for the TRAIL receptor significantly augmented the severity of EC and increased Ag-recall splenocyte IFN-gamma production in vitro. CONCLUSIONS These results indicate that TRAIL receptor-expressing cells in lymphoid organ participate in the development of EC.

Abstract
OBJECTIVES Matrix metalloproteinases (MMPs) regulated by ets transcription factors facilitate carcinoma cell invasion. An ets family member, ESE-1, is expressed specifically in epithelial tissues, but its association with MMPs is obscure. In this study, we investigated whether ESE-1 regulates invasion of oral squamous cell carcinoma (SCC) via transcriptional activity of MMP-9. METHODS HSC-3 and KB were used as human oral SCC lines. The expression of ESE-1 and MMP-9 was detected by in situ hybridization and immunohistochemistry. Invasion assay, gelatin zymography and Northern blotting were used to detect the invasion activity, the gelatinolytic activity and the expression of MMP-9 in the ESE-1 transfectants. Luciferase assays and mutation analysis were used for the transcriptional analysis of MMP-9 promoter region by ESE-1. RESULTS ESE-1 was expressed in the intermediate layer but not in the invasive area, in which MMP-9 was expressed, in the oral SCC tissues. ESE-1 suppressed invasion activity and 92 kDa gelatinolytic activity in HSC-3 as a result of transfection. ESE-1 regulates MMP-9 expression in a negative manner and the ets binding site on the MMP-9 promoter contributed to suppression by ESE-1. CONCLUSIONS These findings indicate that ESE-1 negatively regulates the invasion of oral SCC via transcriptional suppression of MMP-9.
