抄録 We report the case of a 58-year-old Japanese man with bilateral synchronous renal cell carcinoma (RCC). The diameters of the right and left tumors were 56 and 69 mm, respectively. Both tumors were endophytic. Cryoablation with prophylactic embolization was performed for the left tumor, and 1 month later, a right open partial nephrectomy was performed. No recurrence was observed during a 16-month follow-up, and the serum creatinine level has been stable. The prognosis of bilateral synchronous RCC is better than that of dialysis patients. The novel approach of combining cryoablation and partial nephrectomy can achieve good cancer control and renal function in bilateral RCC.

抄録 We experienced a case of advanced maternal age in which a fetus was found to be positive for trisomy 18 at re-examination following indeterminate non-invasive prenatal genetic testing (NIPT), the amniotic fluid chromosomal test revealed a normal karyotype, and confined placental mosaicism (CPM) was observed in an SNP microarray analysis of the placenta. The child was born with no defects or complications. In the present case, the result of the original NIPT at week 15 of pregnancy was indeterminate and the subsequent re-examination result was positive; since the definitive normal diagnosis was not reported until the latter half of week 21, the pregnant patient was subjected to psychological stress for a long period of time. The problem with NIPT is that most of the fetus-derived cell-free DNA in the maternal blood is not derived directly from the fetus but from the villus cells of the placenta, leading to indefinite diagnoses; for that reason, the pregnant patient was subjected to psychological stress for a long period of time. Of the 18,251 cases undergoing NIPT in the past 2 years in Japan, 51 had indeterminate results; this was the second case in which a subsequent re-examination gave a positive result for trisomy 18.

抄録 Newly published clinical practice guidelines recommend intracranial pressure (ICP) monitoring in critical care for the management of pediatric acute encephalopathy (pAE), but the utility of ICP monitoring for pAE has been poorly studied. We recently performed direct ICP monitoring for two patients. We observed that although the direct ICP monitoring had clinical benefits with less body weight gain and no vasopressor use in both cases, this monitoring technique is still invasive. Future studies should determine the utility of non-invasive ICP monitoring systems in pAE to further improve the quality of intensive-care management.

抄録 As a new trial, we used interstitial computed tomography-lymphography (CT-LG) in 10 patients with lower extremity lymphedema (n=20 limbs) at stage 0, 1, 2, or 3 under the International Society of Lymphology (ISL) classification. In all cases, CT-LG, lymphoscintigraphy, and indocyanine green fluorescence-lymphography (ICG-LG) were performed. In the examination of the ascending level of depicted lymphatic vessels, we measured the diameters of lymphatic vessels detected with CT-LG and conducted an image analysis of dermal backflow of lymph (DB). CT-LG had better resolution than lymphoscintigraphy and enabled the clear visualization of lymphatic vessels with a minimum lumen size of 0.7 mm. CT-LG also showed the three-dimensional architecture of the DB, which originated from deep lymphatic collectors via branched small lymphatic vessels. Our findings are quite valuable not only for detailed examinations of lymphedematous sites and for the lymphedema surgery, but also for investigations of the pathogenesis of lymphedema which has not yet been established. We observed that lymphoscintigraphy could show the lymphatic vessels up to the thigh level in all cases, whereas CT-LG enabled the vessels’ visualization up to the leg level at maximum. In conclusion, CT-LG provided adequate and detailed three-dimensional imaging of the lymphatic system in lymphedema patients.

抄録 Although gestational hypertension (GH) is thought to be different from preeclampsia (PE), in Japan GH and PE are usually treated as the same disease (i.e., pregnancy-induced hypertension). Here we sought to determine whether there are any differences in fetal growth and maternal kidney function between pregnancies with PE and those with GH. We retrospectively analyzed 61 GH patients and 60 PE patients with singleton pregnancies who delivered at Okayama University Hospital (2008-2015). We compared maternal and perinatal outcomes and maternal kidney function parameters between the GH and PE pregnancies. The mean values of maternal age (p=0.01), gestational age at delivery (p<0.0001), placental weight (p=0.002), birth weight and height (p<0.0001, p=0.0001), and head circumference standard deviation score (p=0.007) of newborns of the GH group were significantly higher than those of the PE group. The duration until termination of PE or GH was not significantly correlated with kidney function. The birth weight percentile was significantly correlated with kidney function in PE but not GH. However, GH patients with poor kidney function and small-for-gestational age infants showed perinatal outcomes similar to those of the PE group. Monitoring kidney function is thus important for determining the severity of PE and GH.

抄録 The three-dimensional (3D) kinematics of the scapula were analyzed in vivo in 10 patients with scapular and 10 patients with clavicular fracture. Both the injured shoulder and normal contralateral shoulder were evaluated by computed tomography in the neutral and fully elevated positions. 3D rotational and translational movements of the scapula relative to the thorax during arm elevation were analyzed. A computer simulation program was used to compare rotational elevation/depression in the coronal plane, anterior/posterior tilting in the sagittal plane and protraction/retraction in the axial plane between the normal and affected sides. Anterior/posterior translational movement along the X-axis, upward/downward movement along the Y-axis, and lateral/medial movement along the Z-axis in the Euler space during forward elevation were also compared. In scapular fracture, rotational elevation of the scapula decreased in the coronal plane and posterior tilting of the scapula increased in the sagittal plane. Anterior and superior translation were higher in scapular fracture than in the corresponding normal sides. However, no significant abnormal rotational and translational kinematic changes were observed during elevation in clavicular fracture. In vivo 3D computerized motion analysis was useful for evaluating scapular dyskinesis. Scapular fracture can cause scapular dyskinesis, but not all clavicular fractures alter scapular motion biomechanics.

抄録 We compared the toe pinch force in men with and without type 2 diabetes mellitus (T2DM). Sixty-eight male T2DM patients and 35 apparently healthy men matched for age, sex, and body mass index (BMI) were enrolled in this cross-sectional study. We compared the toe pinch force between the subjects with and without T2DM, and we evaluated the effect of diabetic polyneuropathy on toe pinch force in the patients. The toe pinch force of the T2DM patients was significantly lower than that of the subjects without diabetes (3.12±1.22 kg vs. 4.40±1.19 kg, p<0.001). Multiple regression analysis showed that T2DM was a determinant of reduced toe pinch force. In addition, the toe pinch force of patients with diabetic polyneuropathy was significantly lower than that of patients without diabetic polyneuropathy (2.31±0.93 kg vs. 3.70±1.07 kg, p<0.001). Multiple regression analysis showed that diabetic polyneuropathy was a determinant of the toe pinch force in men with T2DM, even after adjusting for age, BMI, HbA1c, and duration of diabetes. Reduced toe pinch force is a fundamental feature of motor dysfunction in men with T2DM, and diabetic polyneuropathy might be associated with toe pinch force in these patients.

抄録 The cluster of differentiation 147 (CD147), also known as EMMPRIN, is a key molecule that promotes cancer progression. We previously developed an adenoviral vector encoding a tumor suppressor REIC/Dkk-3 gene (Ad-REIC) for cancer gene therapy. The therapeutic effects are based on suppressing the growth of cancer cells, but, the underlying molecular mechanism has not been fully clarified. To elucidate this mechanism, we investigated the effects of Ad-REIC on the expression of CD147 in LNCaP prostate cancer cells. Western blotting revealed that the expression of CD147 was significantly suppressed by Ad-REIC. Ad-REIC also suppressed the cell growth of LNCaP cells. Since other researchers have demonstrated that phosphorylated mitogen-activated protein kinases (MAPKs) and c-Myc protein positively regulate the expression of CD147, we investigated the correlation between the CD147 level and the activation of MAPK and c-Myc expression. Unexpectedly, no positive correlation was observed between CD147 and its possible regulators, suggesting that another signaling pathway was involved in the downregulation of CD147. This is the first study to show the downregulation of CD147 by Ad-REIC in prostate cancer cells. At least some of the therapeutic effects of Ad-REIC may be due to the downregulation of the cancer-progression factor, CD147.

抄録 Currently, chemoradiation is the most widely used nonsurgical treatment for esophageal cancer. However, some patients, particularly the very elderly or those with severe vital organ dysfunction, face difficulty with the chemotherapy component. We therefore examined the outcome of radiation therapy (RT) alone for patients with esophageal cancer at our facility. Between January 2005 and December 2014, 84 patients underwent RT at our hospital, and 78 of these patients received concomitant chemotherapy. The remaining 6 patients underwent RT alone; these patients were considered to be high-risk and to have no lymph node metastasis (stage I). Five of them received irradiation up to a curative dose: 4 showed a complete response (CR) and 1 showed a partial response (PR). Of the patients exhibiting CR, 3 are currently living recurrence-free, whereas 1 patient underwent endoscopic submucosal dissection (ESD) as salvage therapy for local recurrence, with no subsequent recurrence. High-risk stage I esophageal cancer patients can be treated radically with RT alone under certain conditions. In the future, to broaden the indications for RT monotherapy to include some degree of advanced cancers, a novel concurrent therapy should be identified.

抄録 Patients with cerebral palsy (CP) frequently present with scoliosis; however, the pattern of curve progression is difficult to predict. We aimed to clarify the natural course of the progression of scoliosis and to identify scoliosis predictors. This was a retrospective, single-center, observational study. Total of 92 CP patients from Asahikawasou Ryouiku Iryou Center in Okayama, Japan were retrospectively analyzed. Cobb angle, presence of hip dislocation and pelvic obliquity, and Gross Motor Function Classification System (GMFCS) were investigated. Severe CP was defined as GMFCS level IV or V. The mean observation period was 10.7 years. Thirtyfour severe CP patients presented with scoliosis and were divided into 3 groups based on their clinical courses: severe, moderate and mild. The mean Cobb angles at the final follow-up were 129°, 53°, and 13° in the severe, moderate, and mild groups, respectively. The average progressions from 18 to 25 years were 2.7°/year, 0.7°/year, and 0.1°/year in the severe, moderate, and mild curve groups, respectively. We observed the natural course of scoliosis and identified 3 courses based on the Cobb angle at 15 and 18 years of age. This method of classification may help clinicians predict the patients’ disease progression.

抄録 Some clinicians have proposed a relationship between gallbladder (GB) cancer and adenomyomatosis (ADM) of the gallbladder, although the latter condition is not considered to have malignant potential. We retrospectively reviewed the surgical pathology database of patients who underwent resection for ADM of the gallbladder at our institution from March 2005 to May 2015. In total, 624 patients underwent surgical resection of the gallbladder with Rokitansky-Aschoff sinuses. Of these cases, 93 were pathologically diagnosed with ADM of the gallbladder, with 44 (47.3%) classified macroscopically as fundal-type ADM, 26 (28.0%) as segmental type, and 23 (24.7%) as diffuse-type ADM. In 3 of the 93 (3.2%) resected specimens, early-stage GB carcinoma was detected, although preoperative imaging did not suggest a malignant neoplasm of the gallbladder in any of these patients. GB cancer subsequently developed in the mucosa of the fundal compartment distal to the annular stricture of the segmental-type ADM in 2 of these patients and against the background of the fundal-type ADM in 1 patient. This study revealed the difficulty of early diagnosis of primary GB cancer in the setting of concurrent ADM, and clinicians should be aware of this frequent coexistence.

抄録 We retrospectively assessed the dual-time-point (DTP) F-18 FDG PET/CT findings of thymic epithelial neoplasms (TENs) and investigated the diagnostic capacity of PET/CT compared to that of CT for predicting carcinoma. We calculated the ratio of the standardized uptake value of the tumor and that of the aortic arch (T/M ratio) for both the 90-min early scan and the 2-h delayed scan in 56 TEN patients. We used a multivariate logistic regression (MLR) analysis to estimate the CT features of carcinoma. We compared the diagnostic capacities of PET/CT and chest CT using receiver operating characteristic (ROC) analyses. The ROC curve revealed that the appropriate cut-off T/M ratio value for the highest accuracy was 2.39 with 75.0% accuracy. The area under the curve (AUC) was 0.855. The statistical analyses for DTP scans of 35 TEN patients demonstrated 74.3% accuracy and 0.838 AUC for the early scan versus 82.9% and 0.825 for the delayed scan. The MLR analysis indicated that mediastinal fat infiltration was a predictor of carcinoma. The ROC curve obtained for the model yielded an AUC of 0.853. Delayed scanning could improve the diagnostic capacity for carcinoma. The T/M ratio and mediastinal fat infiltration are predictive of carcinoma with moderate diagnostic accuracy.

抄録 We retrospectively analyzed the cases of 14 patients (9 women, 5 men, mean age: 51.6 years) with cytomegalovirus (CMV) involvement in the esophagus, stomach, and/or duodenum diagnosed at a single center, to determine their endoscopic features and clinical backgrounds. Thirteen patients (92.9%) had hematologic disease; the other had rheumatoid arthritis. Of the former, 12 patients underwent allogeneic hematopoietic stem cell transplantation, and 9 of these patients had graft-versus-host disease (GVHD) before undergoing esophagogastroduodenoscopy (EGD). All 14 patients had been taking one or more immunosuppressive agents including cyclosporine (n=10), corticosteroids (n=9), mycophenolic acid (n=6), tacrolimus (n=3), and methotrexate (n=1). Tests for CMV antigenemia were positive in 11 patients (78.6%). EGD examinations revealed esophageal (n=3), gastric (n=9), and duodenal involvement (n=6). Macroscopically, esophageal lesions by CMV infection presented as redness (n=1), erosions (n=1), and ulcers (n=1). Gastric lesions manifested as redness (n=7), erosions (n=3), exfoliated mucosa (n=2), and verrucous erosions (n=1). Mucosal appearances in the duodenum varied: redness (n=2), ulcers (n=2), multiple erosions (n=2), single erosion (n=1), edema (n=1). CMV was detected even in the intact duodenal mucosa (n=1). In conclusion, physicians must recall the relevance of CMV infection when any mucosal alterations exist in the upper gastrointestinal tract of immunosuppressed patients.

抄録 The aim of this study was to investigate the utility of single-source dual-energy computed tomography (SS-DECT) composition analysis in characterizing different types of urinary stones and differentiating them from phleboliths. This study included 29 patients with urinary stones who were scheduled for surgery. All patients were scanned, first using single-energy computed tomography acquisition and then DECT acquisition on SS-DECT. Dual-energy data were archived to a Gemstone spectral imaging (GSI) viewer (GE Healthcare, Milwaukee, WI, USA). Hounsfield units (HU) and effective atomic numbers (Zeff) were estimated using the GSI viewer. The results of dual-energy analysis were compared with the biochemical constitution of the stones. The chemical analysis determined that the stones included 32 calcium-based, 6 cystine and 1 struvite stone. Both HU and Zeff values were helpful in differentiating calcium-based stones from cystine and struvite stones and phleboliths. The Zeff values of phleboliths were significantly higher than those for struvite and cystine stones, whereas it was difficult to distinguish phleboliths from struvite and cystine stones using the HU values. Composition analysis using SS-DECT is helpful for distinguishing urinary stone types and discriminating phleboliths from urinary stones. Zeff values may be more useful than HU values for differentiating urinary stones from phleboliths.
