Abstract
OBJECTIVES To investigate the influence of filler type/loading on the micro-tensile fracture strength (μTFS) of adhesive resins, as measured 'immediately' upon preparation and after 1-week water storage ('water-stored'). METHODS The morphology and particle-size distribution of three filler particles, referred to as 'Glass-S' (Esschem Europe), 'BioUnion' (GC), and 'CPC_Mont', were correlatively characterized by SEM, TEM, and particle-size analysis. These filler particles were incorporated into an unfilled adhesive resin ('BZF-29unfilled', GC) in different concentrations to measure the 'immediate' μTFS. After 1-week water storage, the 'water-stored' μTFS of the experimental particle-filled adhesive resins with the most optimum filler loading, specific for each filler type, was measured. In addition, the immediate and water-stored μTFS of the adhesive resins of three experimental two-step universal adhesives based on the same resin matrix but varying for filler type/loading, coded as 'BZF-21' (containing silica and bioglass), 'BZF-29' (containing solely silica), and 'BZF-29_hv' (highly viscous with a higher silica loading than BZF-29), and of the adhesive resins of the gold-standard adhesives OptiBond FL ('Opti-FL', Kerr) and Clearfil SE Bond 2 ('C-SE2', Kuraray Noritake) was measured along with that of BZF-29unfilled (GC) serving as control/reference. Statistics involved one-way and two-way ANOVA followed by post-hoc multiple comparisons (α<0.05). RESULTS Glass-S, BioUnion, and CPC_Mont represent irregular fillers with an average particle size of 8.5-9.9 μm. Adding filler to BZF-29unfilled decreased μTFS regardless of filler type/loading. One-week water storage reduced μTFS of all adhesive resins except BZF-21, with the largest reduction in μTFS recorded for BZF-29unfilled. Among the three filler types, the μTFS of the 30 wt% Glass-S and 20 wt% BioUnion filled adhesive resin was not significantly different from the μTFS of BZF-29unfilled upon water storage. CONCLUSIONS Adding filler particles into adhesive resin did not enhance its micro-tensile fracture strength but appeared to render it less sensitive to water storage as compared to the unfilled adhesive resin investigated.

Abstract
The selection of anticoagulant therapy and appropriate duration of treatment for central venous (CV) catheter-associated internal jugular vein thrombosis in patients with malignant lymphoma remain unclear. Two cases of aggressive B-cell lymphomas treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone), in which apixaban administered for less than three months was effective against CV catheter-associated internal jugular vein thrombosis, are reported. In one case, the right internal jugular vein thrombosis developed after eight courses of R-CHOP; when apixaban was orally administered for 37 days after the CV catheter was removed, the thrombus completely dissolved and did not recur for 27 months. In the other case, right internal jugular vein thrombosis developed after four courses of R-CHOP; two additional courses of the R-CHOP were administered alongside oral apixaban administration without catheter removal. After 66 days of oral apixaban, the thrombus completely dissolved, the CV catheter was removed, and no recurrence was observed for 8.5 months.

Abstract
AIM To evaluate the efficacy of using the central venous (CV) port compared with peripheral intravenous access for contrast-material injection for contrast enhancement during the portal venous phase. MATERIALS AND METHODS Patients were divided into three groups: CV delay, CV routine, and peripheral access (PA) groups. Patients in the CV delay group underwent injection in the arm-down position with an additional delay, while those in the CV routine and PA groups underwent injections with the routine injection protocol for portal venous phase imaging. Contrast enhancement was evaluated by measuring the mean radiodensity (Hounsfield units) values for the aortic arch, abdominal aorta, inferior vena cava, portal vein, and spleen. The peak injection pressure was recorded and compared among the three groups. RESULTS No complications related to power injection were observed during 119 contrast-material injections performed using the CV port device. The CV delay group showed significantly lower radiodensity values than the PA group (165.7 ± 20.1 versus 181 ± 19 HU [p<0.01] for the portal vein); however, no significant differences in mean radiodensity values were observed between the CV routine and PA groups (p>0.05). The median peak injection pressure was 73.5, 67, and 47 psi in the CV delay, CV routine, and PA groups, respectively (p<0.01). CONCLUSION The CV port can be used for safe contrast-material injection while maintaining contrast enhancement on portal venous phase comparable to that achieved with peripheral intravenous access.

Abstract
The long-term survival rate of hematological malignancy patients with Global Leadership Initiative on Malnutrition (GLIM)-defined malnutrition and sarcopenia is poor, but nutritional rehabilitation effects in such patients are unknown. Here, two cases of older hematological malignancy patients in whom nutritional rehabilitation was effective against GLIM-defined malnutrition and sarcopenia are reported. By undergoing nutritional rehabilitation, the myeloma patient increased her six-meter walking speed and her maintained body mass index (BMI), appendicular skeletal muscle mass (ASM), and hand grip strength, whereas the Hodgkin lymphoma patient regained his hand grip strength and maintained his BMI, ASM, and six-meter walking speed.

Abstract
Abstract
Background
Obesity carries independent risk for incident atrial fibrillation (AF), although the impact of abdominal fat distribution on LA morphological and functional remodeling is not fully elucidated. Speckle-tracking echocardiography is a novel and sensitive tool that allows quantification and detection of subtle alterations in left atrial (LA) phasic function.
Purpose
This study aimed to investigate whether increased visceral adiposity is independently associated with impaired LA phasic function in a community-based cohort.
Methods
We included 527 participants without overt cardiac disease who underwent laboratory testing, abdominal computed tomographic examination and speckle-tracking echocardiography. Abdominal adiposity was quantitatively assessed as visceral fat area (VFA) and subcutaneous fat area (SFA) at the level of the umbilicus. Speckle-tracking echocardiography was performed to assess LA phasic function including reservoir, conduit and pump strain as well as left ventricular global longitudinal strain (LVGLS).
Results
Mean age was 57±10 years and 362 of the participants (69%) were men. LA reservoir and conduit strain were decreased according to the VFA quartiles (both p<0.05), whereas there was no significant difference in LA volume index and LA pump strain. When stratified by SFA, there was no significant differences in LA volume index and all LA phasic strain across the quartiles. In multivariable analysis, VFA as continuous variable was significantly associated with LA conduit strain, independent of traditional cardiovascular risk factors, pertinent laboratory parameters and LV morphology and function including LVGLS (standardized b=−0.146, p=0.011). Representative cases are shown in the Figure.
Conclusion
In a sample of the general population, VFA accumulation was independently associated with worse LA conduit strain, which may be involved in the pathophysiological mechanism of obesity-related AF.

Abstract
Abstract
Background
Although carotid intima-media thickness (IMT) is an established marker of atherosclerosis and carries independent risk for cardiovascular disease, its possible association with subclinical cardiac dysfunction has not been extensively evaluated. Left ventricular global longitudinal strain (LVGLS) and peak left atrial longitudinal systolic strain (PALS) can detect subclinical left heart dysfunction.
Purpose
This study aimed to investigate the association between carotid IMT and subclinical left heart dysfunction in a large sample of the general population without overt cardiac disease.
Methods
We examined 1,161 participants who underwent extensive cardiovascular examination. Ultrasonography of common carotid artery was performed for the measurement of maximal carotid IMT. LVGLS and PALS were assessed by 2-dimensional speckle-tracking echocardiography.
Results
Mean age was 62±12 years, and 56% were male. The prevalence of abnormal LVGLS (>−18.6%) and PALS (<31.4%) was greatest in the upper quartile of carotid IMT (both p<0.001; Figure). In multivariable analyses, carotid IMT was associated with abnormal LVGLS (adjusted odds ratio = 1.33 per 1SD increase of IMT, p=0.003) as well as PALS (adjusted odds ratio = 1.33 per 1SD increase of IMT, p=0.005) independent of traditional cardiovascular risk factors, echocardiographic parameters including LV ejection fraction, LV mass index and diastolic dysfunction, and pertinent laboratory parameters. The independent association between carotid IMT and PALS persisted even after adjustment for LVGLS. When carotid IMT was examined as a categorical variable, the upper quartile of carotid IMT carried a significant risk of abnormal LVGLS and PALS in a fully-adjusted model including echocardiographic and laboratory parameters (adjusted odds ratio 2.27 and 3.03 vs. lower quartile, both p<0.01).
Conclusion
Participants with increased IMT had significantly impaired LV and LA function in an unselected community-based cohort. This association may be involved in the higher incidence of cardiovascular disease in individuals with increased carotid IMT.

Abstract
Abstract
Background
Increased arterial stiffness has been proposed as one of the key mechanisms of incident heart failure with preserved ejection fraction (HFpEF). However, the possible association between arterial stiffness and subclinical left ventricular (LV) dysfunction and possible sex-specific differences remain unclarified. LV strain is emerging as a highly sensitive tool to unmask early LV abnormalities.
Purpose
We investigated whether increased arterial stiffness is independently associated with subclinical LV dysfunction in a large community-based cohort without overt cardiovascular disease.
Methods
We examined 1,155 participants who underwent extensive cardiovascular examination. Speckle-tracking echocardiography was employed to assess LV global longitudinal strain (LVGLS) and circumferential strain (GCS), and arterial stiffness was assessed by cardio-ankle vascular index (CAVI).
Results
Mean age was 62±12 years, and 56% were male. CAVI as continuous variable was associated with abnormal LVGLS (>−18.6%), independent of cardiovascular risk factors and pertinent laboratory and echocardiographic parameters (adjusted odds ratio [OR] 1.23, p=0.034), whereas there was no relationship with LVGCS. In sex-stratified analysis, more pronounced association between quartiles of CAVI and abnormal LVGLS was observed in women than in men (unadjusted OR = 6.43 in women and 2.46 in men for upper quartile vs. lower quartile, both p<0.01; Figure). Multivariable analyses demonstrated that CAVI was significantly associated with abnormal LVGLS independent of cardiovascular risk factors in both sexes. However, after further adjustment for LV mass index and diastolic parameters, the independent association persisted in women (adjusted OR 1.49, p=0.041), but not in men (adjusted OR 1.15, p=0.209).
Conclusion
Increased arterial stiffness was independently associated with decreased LVGLS even in the absence of overt cardiovascular disease; a sex-specific pattern exists in the alteration of vascular-ventricular coupling, which might partially explain the greater susceptibility to HFpEF in women.

Abstract
Abstract
BACKGROUND
Left ventricular function has been shown to be an important prognostic indicator in patients with repaired tetralogy of Fallot (rTOF) and tends to decrease with age. In recent years, left atrial (LA) function was reported to be a useful prognostic indicator more than or equal to left ventricular function in acquired heart diseases. However, atrial function in rTOF has not yet been sufficiently examined.
PURPOSE
The aim of this study was to investigate the relationship between LA dysfunction and age in rTOF using strain analysis.
METHODS
In order to assess the relationship between LA function and age, we recruited 59 patients with rTOF ranging in age from 5-40 years. We stratified the patients into 3 groups (T1: 5-10 years, T2: 11-20 years, T3: 21-40 years) and divided 54 controls of similar age into 3 corresponding groups (N1, N2, and N3). Two-dimensional speckle tracking images (2D-STI) obtained from four- and two-chamber views were used to assess LA functions by measuring reservoir, conduit, and pump strain. Additionally, we measured the strain rate (SR) in the systole, early diastole, and late diastole.
RESULTS
LA reservoir strain (37.4 ± 2.2% vs. 47.9 ± 1.7%, P= 0.004), LA pump strain (8.3 ± 1.4% vs. 14.1 ± 2.7%, p <.001), atrial systolic LA-SR (1.5 ± 0.4% vs. 2.4 ± 0.6%, p <.001), and systolic LA-SR (1.5 ± 0.3% vs. 2.1 ± 0.4%, p = 0.003) were significantly decreased in T3 compared with N3. Although only LA conduit strain decreased with aging (r = -0.3204, p = 0011) in controls, all of the LA reservoir (r = -0.325, p = 0.020), conduit (r = -0.314, p = 0.025), and pump strain (r = -0.481, p < 0.001) in rTOF decreased with aging.
Early diastole SR was significantly decreased in the T1 and T3 groups compared with the N1 and N3 groups (T1 vs N1, 3.00 ± 0.63% vs. 4.03 ± 0.0.80%, p <.0.001, T3 vs N3, 2.31 ± 0.57% vs.3.31 ± 0.47%, p < 0.001). Both systolic SR and late diastole SR decreased in T3 group compared with the N3 (1.54 ± 0.32% vs. 2.08 ± 0.42%, p = 0.003, 1.42 ± 0.32% vs.2.42 ± 0.61%, p < 0.001), respectively. Although only early diastole SR decreased with aging (r = -0.415, p < 0.001) in controls, all of the systole (r = -0.287, p = 0.041), early diastole (r = -0.337, p = 0.019), and late diastole SR (r = -0.407, p = 0.003) in rTOF decreased with aging.
CONCLUSIONS
In rTOF, most of the LA functions assessed by strain analysis decreased compared to normal controls in over 20 years old age. Furthermore, all measured functions decreased with age in rTOF while only two parameters decreased with age in normal controls. These results suggest that LA function may be an important indicator in long-term rTOF follow-up. These are new insights into LA function in patients with rTOF.

Abstract
Abstract
Background
American College of Cardiology (ACC) and American Heart Association (AHA) revised their guideline for hypertension in 2017, and the threshold of normal blood pressure (BP) was lowered, in the perspective of the prevention of optimal prevention of cardiovascular diseases. On the other hand European Society of Cardiology and European Society of Hypertension updated their guideline in 2018. However, the cut off value of blood pressure for hypertension was not changed (sBP ≥ 140 mmHg or dBP ≥ 90 mmHg). Therefore, the validity of the updated guideline of ACC/AHA still remains controversial, and there is so far no evidence regarding the BP category according to the ACC/AHA guidelines in general population.
Purpose
We aimed to clarify the association between the updated BP classification and carotid intima-media thickness (IMT), as a marker of subclinical atherosclerosis, in general population using a community-based cohort.
Methods
We analyzed 1,241 subjects undergoing medical check-ups at the University of Tokyo Hospital. Study subjects were categorized into 3 groups based on their BP levels: normal pressure (sBP < 130 mmHg and dBP < 80 mmHg); stage 1 hypertension (130 mmHg ≤ sBP < 140 mmHg or 80 mmHg ≤ dBP< 90 mmHg); and stage 2 hypertension (sBP ≥ 140 mmHg or dBP ≥ 90 mmHg, including subjects prescribed with antihypertensive agents). We defined carotid plaque as IMT ≥ 1.1 mm.
Results
Out of 1,241 subjects, 556 patients (44.8%) were categorized in the normal BP group, whereas 236 subjects (19.0%) and 449 subjects (36.2%) were categorized in the stage 1 and stage 2 hypertension groups, respectively. Among subjects categorized in the stage 2 hypertension group, 348 subjects (77.5%) patients were taking antihypertensive medications. Percentage of male gender, and age increased with BP category. Classical CVD risk factors such as diabetes mellitus and hypercholesterolemia were common in subjects in the hypertension groups. IMT increased as the BP category progressed from normal BP to stage 2 hypertension. The prevalence of carotid plaque also increased with an increase in BP. Univariate regression analysis showed the linear association between the BP category and prevalence of carotid plaque. Multivariable logistic regression analysis demonstrated that BP category as well as age ≥60 years, male gender, body mass index ≥25 kg/m2, and diabetes mellitus were independently associated with carotid plaque formation. BP category was associated with the prevalence of carotid plaque formation in any subgroup divided by age (< 60 years old, and ≥60 years old) or gender.
Conclusions
Thickening of IMT developed in stage 1 hypertension, and further increased in stage 2 hypertension even in general population, indicating the importance of the therapeutic intervention according to the updated ACC/AHA guideline for hypertension.

Abstract
Abstract
Background
Increased arterial stiffness is recognized as an independent risk factor for atrial fibrillation, although the pathophysiological mechanisms remain unclear. Cardio-ankle vascular index (CAVI) is emerging as an important tool to assess arterial stiffness noninvasively which is derived from the concept of stiffness β index and is less dependent on blood pressure at the time of measurement than pulse wave velocity.
Purpose
This study aimed to investigate the association of arterial stiffness with left atrial (LA) volume and phasic function in a community-based cohort.
Methods
We included 1,156 participants without overt cardiovascular disease who underwent extensive cardiovascular examination. Arterial stiffness was evaluated by CAVI. Speckle-tracking echocardiography was employed to evaluate LA phasic function including reservoir, conduit and pump strain as well as left ventricular global longitudinal strain (LVGLS).
Results
CAVI was negatively correlated with reservoir and conduit strain (r=−0.37 and −0.45, both p<0.001; Figure), whereas weakly, but positively correlated with LA volume index and pump strain (r=0.12 and 0.09, both p<0.01). In multivariable analysis, CAVI was significantly associated with reservoir and conduit strain independent of traditional cardiovascular risk factors, pertinent laboratory parameters and LV morphology and function including LVGLS (standardized β=−0.22 and −0.26, respectively, both p<0.001), whereas there was no independent association with LA volume index and pump strain. In the categorical analysis, the abnormal CAVI (≥9.0) carried the significant risk of impaired reservoir (<31.4%) and conduit (<12.4%) strain (adjusted odds ratio = 2.63 and 3.71 vs. normal CAVI, both p<0.01) in a fully-adjusted model including laboratory and echocardiographic parameters.
Figure 1
Conclusion
Arterial stiffness was independently associated with LA reservoir and conduit function, even in the absence of overt cardiovascular disease. This association may explain the higher incidence of atrial fibrillation in individuals with increased arterial stiffness.

Abstract
Abstract
Introduction
Obesity is a common and independent risk factor for all-cause mortality. More specifically, obesity is a major component of atherosclerosis in association with metabolic disorders including metabolic syndrome (MetS), resulting in various cardiovascular diseases (CVD). Alternatively, obese subjects without MetS are prevalent, also referred to as metabolically healthy obesity (MHO). However, most preceding studies regarding MHO have been limited by small cohorts. Therefore, the effect of MHO on atherosclerosis in the general population remains unclear.
Purpose
In this study, we sought to clarify the effect of MHO on carotid intima-media thickness (IMT) as a marker of early stage atherosclerosis using a community-based cohort in general population.
Methods
We examined subjects who underwent medical check-up at our University Hospital. We defined obesity as body mass index ≥25.0 kg/m2. Abdominal obesity, defined as waist circumstance at umbilical level ≥85 cm in men and ≥90 cm in women, was obligatory for the diagnosis of MetS. In addition to abdominal obesity, any two of the following three abnormalities should be observed for the diagnosis of MetS, [1] Dyslipidemia: triglyceride ≥150 mg/dL, HDL-C <40 mg/dL, or use of lipid lowering medication, [2] Hypertension: systolic blood pressure ≥130 mmHg, diastolic blood pressure ≥85 mmHg, or use of antihypertensive medication, and [3] Hyperglycemia: fasting plasma glucose ≥110 mg/dL or use of hypoglycemic medication. MHO was defined as obese subjects without MetS, whereas we defined metabolically unhealthy obesity (MUO) as obese subjects with MetS. We defined carotid plaque as IMT ≥1.1 mm.
Results
Among 1,241 subjects, 857 subjects (69%) were categorized in the normal body weight group, whereas 275 subjects (22%) were categorized as MHO, and 109 subjects (9%) were categorized as MUO. Compared to non-obese subjects, prevalence of classical cardiovascular risk factors including hypertension, diabetes mellitus, and dyslipidemia increased in subjects with MHO, and further increased in those with MUO. IMT was higher in obese subjects compared to those without obesity. Similarly, the prevalence of carotid plaque formation was also higher in obese subjects. Multivariable logistic regression analysis demonstrated that age ≥60 years, male sex, hypertension, diabetes mellitus, MHO subjects (Odds ratio [OR]; 1.6, p=0.005), and MUO subjects (OR 1.7, p=0.04) were independently associated with carotid plaque formation. There was no statistical difference in the risk of carotid plaque formation between subjects with MHO and MUO.
IMT and Carotid Plaque
Conclusions
IMT and the prevalence of carotid plaque are higher in both subjects with MHO and MUO compared to non-obese subjects in the general population. We need to take obesity regardless of the presence of MetS into consideration as high-risk subjects for subsequent CVD.

Abstract
Abstract
Background
Cigarette smoking is closely associated with the development of cardiovascular diseases (CVD), and the European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) guidelines recommend smoking bans.On the other hand, the relationship between cigarette smoking and subclinical atherosclerosis has not been fully studied. Carotid intima-media thickness (cIMT) is commonly used as a subclinical atherosclerosis marker, and a carotid plaque feature is also known to be an important predictor of cardiovascular diseases.
Purpose
We sought to clarify the association between cigarette smoking and subclinical atherosclerosis by evaluating carotid plaque including cIMT and carotid plaque features in general population.
Methods and results
Among 1,209 participants with no prior coronary artery disease who received a medical check-up with cardiovascular examination at our institution, 450 participants (37.2%) were smokers (including both past and current smokers). We defined carotid plaque as cIMT ≥1.1 mm and high-risk plaque as carotid plaque with hypoechoic dominant and/or plaque ulceration. The value of cIMT and the rate of carotid plaque were not different between smokers and never smokers (Figure A & B). However, the rate of carotid high-risk plaque was significantly higher in participants with smokers than those with never smokers (29.7%, vs 23.5%, p=0.011) (Figure C). Even after adjustment with covariates including age, gender and traditional cardiovascular risk factors, cigarette smoking was independently associated with high-risk plaque formation (odds ratio 1.384, 95% CI 1.020–1.877; p=0.037). According to the subgroup analysis classified by age, cigarette smoking was associated with not only the development of high-risk plaque but also the increased value of cIMT in the subgroup over 60 years old, whereas only the rate of high-risk plaque was higher in smokers than never smokers in the subgroup under 60 years old.
Carotid plaque and smoking
Conclusion
The development of high-risk carotid artery plaque may precede thickening of cIMT in cigarette smokers, suggesting that the novel insight for the pathological mechanism underlying cardiovascular events and cigarette smoking.

Abstract
We report a case of malignant triton tumor of the duodenum, which is extremely rare. A submucosal malignant tumor was detected in the duodenum of a 49-year-old woman. The tumor was completely resected by performing pancreaticoduodenectomy. Pathological examination revealed that the lesion was a malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation, i.e., a malignant triton tumor. Long-term survival has been achieved with no recurrence at 8.5 years after surgery.

Abstract
Fournier's gangrene (FG) is a fulminant infective necrotizing fasciitis, which includes the genital, perineal, and perianal regions. A 77-year-old man had previously been diagnosed as having diabetes mellitus (DM) and was treated with pioglitazone (15 mg) and miglitol (150 mg). He developed sudden perineal discomfort, fever with painful penile, and scrotal edema, subsequently leading to urinary retention. According to physical examination and CT scan results for the swollen penis and scrotum, he was diagnosed with FG. FG was eventually controlled by extensive treatment with broad spectrum antibiotics and repeated surgical debridement including penectomy and scrotectomy. He showed persistent anemia and decreased neutrophils exhibiting hypogranulation. Bone marrow aspiration revealed hypercellularity with 9% myeloblasts, micromegakaryocytes, abnormal leukocyte granulation, and erythrocytic dyspoiesis, leading to a diagnosis of myelodysplastic syndrome (MDS) RAEB-1, and he was evaluated as high risk according to IPSS-R. After 4 courses of azacitidine treatment, he achieved HI-E and had no further recurrence of FG for more than 18 months. Although DM and alcohol misuse are common systemic comorbidities in patients with FG, MDS should be considered in elderly FG cases, even when DM complications are present.

Abstract
A collateral pathway established after lymphadenectomy could play an important role in long-term lymphedema treatment. The present study investigated alterations of lymph dynamics 1 year after lymphadenectomy using indocyanine green fluorescent lymphography to determine if a collateral pathway may be used for long-term lymphedema treatment. Wistar rats were anaesthetized and lymph nodes were excised at the inguinal and popliteal fossae. The treated hind limb was evaluated by fluorescent lymphography between 10 weeks and 6 months and between 6 months and 1 year postoperatively. Fluorescent lymphography demonstrated a lymphatic pathway to the ipsilateral axillary fossa in all rats 1 year after lymphadenectomy. Some capillary branches in the paths leading to the ipsilateral axillary fossa were dilated and tortuous. In addition, areas in which a fluorescent signal was not visible were increased in the thigh. In conclusion, the collateral pathway did not appear to be only for temporary use to compensate for drainage from the edematous limb but appears more stable as a component of a compensating lymphatic system. These new dilated vessels, although functional at this point, may still be susceptible to disturbance by further alteration to the lymph vessels.

Abstract
In order to determine the value of sonography (US), in staging cancer of the mobile tongue, 57 patients were studied prospectively. Real-time sector scanners (5 and 7.5 MHz) were used with a submental approach. The findings by US were compared with those obtained by inspection and palpation and in 13 operated patients with the surgical results. US failed to visualize the tumor in 3 of the 57 patients (5%); in 30 patients (53%), the tumor was considered to be of nearly the same size by US and by palpation, but in 17 cases (30%), to be larger by US than by palpation, and in the remaining 7 cases (12%), to be smaller by US. Extension across the midline (8/8), and depth of tumor penetration, or extension to adjacent structures (5/5) were more correctly evaluated by US. We conclude that US is useful for staging work-up of tumors of the mobile tongue.

Abstract
To evaluate the effect of transcatheter arterial chemoembolization (TACE) with iodized oil for hepatocellular carcinoma (HCC), dynamic turbo-fast low angle shot (turbo-FLASH) (TR/TE/flip angle/TI, 8.5/4.6/10/200) MR imaging with gadopentetate dimeglumine was performed in 10 patients with HCC after TACE with iodized oil and before partial hepatectomy. Immediately after 0.05 mmol/kg b.w. of gadopentetate dimeglumine was administered intravenously, 10 images were obtained in the first 20 s (early phase). Then, one image every 30 s from 1 to 3 min (late phase), and images at 5 min and 7 min (delayed phase) were obtained serially. In the early phase, HCC showed no enhancement in 5 patients, partial hyperintense enhancement in 4, and total hyperintense enhancement in one. Viable regions of the tumor, evaluated at histopathology, showed hyperintense enhancement relative to the surrounding liver parenchyma in the early phase, while necrotic regions showed no enhancement. Both viable and necrotic regions showed lower signal intensities than the surrounding liver parenchyma in both late and delayed phases. By using dynamic turbo-FLASH MR imaging, we were able to accurately evaluate the effect of TACE with iodized oil for HCC in 8 of the 10 patients. In 2 patients, in whom small viable cells were seen in the HCC, viable regions could not be detected with our technique. It is concluded that turbo-FLASH dynamic MR imaging was useful for evaluating the effect of TACE for HCC.

Abstract
Computed tomography of the chest following endoscopic injection sclerotherapy for esophageal varices was performed in 17 procedures in 13 patients. CT scans were obtained before and within 48 hours after the procedure. CT findings included: esophageal wall thickening; a low-attenuating lesion within the wall of the esophagus with varying appearances, either laminated, localized, or inhomogeneous; a mediastinal lesion; pleural effusion; and various types of pulmonary changes such as atelectasis, pleural-based lesions, dilatation of peripheral pulmonary vessels, and nodular lesions. However, on follow-up CT they had regressed or disappeared. The changes in the mediastinum and pleural space might be caused by direct extension of inflammation from the esophagus, but those in the lungs, especially dilatation of peripheral vessels, may be caused by the sclerosing agent passing to the pulmonary vessels.

Abstract
PURPOSE The authors report on a rare case of maternal virilization during pregnancy caused by autosomal recessive P450 oxidore- ductase (POR) deficiency. MATERIALS AND METHODS A 24-year-old primigravida developed a deepening voice and hirsutism in the second trimester. Prenatal ultrasonography failed to detect any fetal abnormality and fetal growth was normal. POR deficiency was suspected, but the mother declined fetal genetic testing. A female neonate was delivered by cesarean section at 41 weeks' gestation. RESULTS The neonate had skeletal abnormalities. Mutational analysis of the POR gene demonstrated homozygosity for c.1370 G>A and p.R457H in the patient and heterozygosity in her parents. POR deficiency was confirmed in the neonate. CONCLUSION POR deficiency should be suspected in cases of maternal virilization. Maternal urinary estriol, fetal magnetic resonance imaging, and parental genetic testing should be performed. Parental consent for fetal genetic testing should be sought to ensure prompt diagnosis and early treatment.

Abstract
BACKGROUND The aim of this study was to evaluate whether MRI at 3 T with superparamagnetic iron oxide (SPIO) enhancement is an accurate and useful method for detecting metastases in sentinel nodes identified by CT-lymphography (CT-LG) in patients with breast cancer. The results were compared with those obtained using CT-LG alone and diagnosing metastasis according to size criteria. METHODS Patients with clinically node-negative breast cancer were included. Sentinel nodes identified by CT-LG were evaluated prospectively using SPIO-enhanced MRI at 3 T. Sentinel node size was measured on CT-LG, and a node larger than 5 mm in short-axis diameter was considered metastatic. Sentinel nodes localized by CT-LG were removed, and imaging results and histopathological findings were compared. RESULTS Sentinel nodes were identified successfully by CT-LG in 69 (99 per cent) of 70 patients. All 19 patients with a finding of metastasis in sentinel nodes at pathology were also shown to have metastases on MRI. Forty-eight of 50 patients with non-metastatic sentinel nodes diagnosed at pathology were classified as having non-metastatic nodes on MRI. On a patient-by-patient basis, the sensitivity, specificity and accuracy of MRI for the diagnosis of sentinel node metastases were 100, 96 and 97 per cent; respective values for CT-LG were 79, 56 and 62 per cent. The specificity and accuracy of MRI were superior to those of CT-LG (P < 0·001 and P = 0·002 respectively). CONCLUSION SPIO-enhanced MRI at 3 T is useful for accurate diagnosis of metastatic sentinel nodes, indicating that sentinel node biopsy may be avoided in patients with breast cancer who have non-metastatic sentinel nodes on imaging.

Abstract
Pazopanib, an oral tyrosine kinase inhibitor, is the first molecular-targeted agent approved for the treatment of advanced soft tissue sarcoma(STS). Rhabdomyosarcoma in adults is rare, accounting for less than 3%of all adult STS cases. A 57-year old woman presented with cervical lymphadenopathy. Computed tomography revealed a heterogeneous mass in the retroperitoneum, replacing the entire right kidney. On the basis of the above findings, the patient was diagnosed with alveolar rhabdomyosarcoma. She was first treated with 4 courses of vincristine, actinomycin D, and cyclophosphamide(VAC), which resulted in a partial response. Dose reduction and delay occurred owing to hematological toxicity and febrile neutropenia. As second-line chemotherapy, the patient was administered a single daily dose of 800 mg of pazopanib. Because of an episode of hand-foot syndrome and hepatic impairment, the 800-mg daily dose of pazopanib was reduced to a daily dose of 600 mg, which had to be further reduced to a daily dose of 400 mg owing to fatigue and anorexia. The patient maintained a partial response for a total of 4.3 months when treated with pazopanib. Therefore, this drug may be a new treatment option for patients showing metastatic STS after previous chemotherapy.

Abstract
Long-duration γ-ray bursts are associated with the explosions of massive stars and are accordingly expected to reside in star-forming regions with molecular gas (the fuel for star formation). Previous searches for carbon monoxide (CO), a tracer of molecular gas, in burst host galaxies did not detect any emission. Molecules have been detected as absorption in the spectra of γ-ray burst afterglows, and the molecular gas is similar to the translucent or diffuse molecular clouds of the Milky Way. Absorption lines probe the interstellar medium only along the line of sight, so it is not clear whether the molecular gas represents the general properties of the regions where the bursts occur. Here we report spatially resolved observations of CO line emission and millimetre-wavelength continuum emission in two galaxies hosting γ-ray bursts. The bursts happened in regions rich in dust, but not particularly rich in molecular gas. The ratio of molecular gas to dust (<9-14) is significantly lower than in star-forming regions of the Milky Way and nearby star-forming galaxies, suggesting that much of the dense gas where stars form has been dissipated by other massive stars.

Abstract
BACKGROUND The pathophysiology of intra-abdominal adhesions has not been studied extensively. The aim of this study was to elucidate the molecular mechanisms underlying adhesion formation in a murine model and in patients undergoing hepatectomy. METHODS Partial hepatectomy was performed using bipolar forceps in mice. Wild-type mice, antibodies to CD4 and interferon (IFN) γ, IFN-γ, natural killer T (NKT) cells and plasminogen activator inhibitor (PAI) 1 knockout (KO) mice were used. Recombinant hepatocyte growth factor (HGF) was tested for its ability to prevent adhesions. Liver specimens were obtained during surgery from patients undergoing hepatectomy. Adhesion formation was evaluated using a scoring system that ranged from 0 (no adhesions) to 5 (severe adhesions). Levels of IFN-γ and PAI-1 mRNA, and protein concentration of PAI-I were measured, and fluorescence immunostaining was performed. RESULTS Adhesion formation depended on IFN-γ produced by NKT cells, and NKT KO mice developed few adhesions (mean(s.d.) 1·7(0·3) versus 4·6(0·4) in wild-type mice; P = 0·037). In wild-type mice, the level of PAI-1 mRNA increased after hepatectomy, followed by a decrease in the tissue plasminogen activator (tPA) mRNA level. Adhesion formation was inhibited completely in PAI-1 KO mice (0(0) versus 4·1(0·8) in wild-type mice; P = 0·002). HGF inhibited formation of abdominal adhesions after hepatectomy by reducing IFN-γ and PAI-1 levels, and increasing tPA levels compared with those in mice treated with phosphate-buffered saline (P < 0·001, P = 0·002 and P = 0·035 respectively). In human liver specimens, NKT cells accumulated in the liver after hepatectomy, and PAI-1 expression was increased 5·25-fold (P = 0·030). CONCLUSION IFN-γ is a key molecule for abdominal adhesion formation after hepatectomy, acting via the reciprocal balance of PAI-1 and tPA. This molecular mechanism may also regulate adhesion formation in patients following hepatectomy. HGF inhibited formation of adhesions by regulating IFN-γ and PAI-1, suggesting that it may be an important target for prevention of adhesions after hepatectomy. SURGICAL RELEVANCE: Postoperative intra-abdominal adhesions can be asymptomatic or cause significant morbidity and mortality. Adhesion formation after hepatectomy has not been studied extensively. In the present study, the molecular mechanisms underlying intra-abdominal adhesions after hepatectomy were investigated in a murine model and in patients. Interferon (IFN) γ produced by natural killer T cells is a key molecule for adhesion formation after hepatectomy in mice, acting via the reciprocal balance between plasminogen activator inhibitor (PAI) 1 and tissue plasminogen activator, the pivotal factors in fibrinolytic activity. This mechanism was also involved in the regulation of adhesions in human tissue samples. Hepatocyte growth factor (HGF) strongly inhibited adhesion formation by regulating IFN-γ and PAI-1. These results indicate that IFN-γ and PAI-1 are possible therapeutic targets, and HGF could prevent postoperative adhesion formation after hepatectomy.

Abstract
Gamow-Teller (GT) transitions in atomic nuclei are sensitive to both nuclear shell structure and effective residual interactions. The nuclear GT excitations were studied for the mass number A = 42, 46, 50, and 54 "f-shell" nuclei in ((3)He, t) charge-exchange reactions. In the (42)Ca → (42)Sc reaction, most of the GT strength is concentrated in the lowest excited state at 0.6 MeV, suggesting the existence of a low-energy GT phonon excitation. As A increases, a high-energy GT phonon excitation develops in the 6-11 MeV region. In the (54)Fe → (54)Co reaction, the high-energy GT phonon excitation mainly carries the GT strength. The existence of these two GT phonon excitations are attributed to the 2 fermionic degrees of freedom in nuclei.
