Abstract
BACKGROUND AND PURPOSE Noninvasive perfusion-weighted imaging with short scanning time could be advantageous in order to determine presumed penumbral regions and subsequent treatment strategy for acute ischemic stroke (AIS). Our aim was to evaluate interobserver agreement and the clinical utility of intravoxel incoherent motion MR imaging in patients with acute ischemic stroke. MATERIALS AND METHODS We retrospectively studied 29 patients with AIS (17 men, 12 women; mean age, 75.2 [SD, 12.0 ] years; median, 77 years). Each patient underwent intravoxel incoherent motion MR imaging using a 1.5T MR imaging scanner. Diffusion-sensitizing gradients were applied sequentially in the x, y, and z directions with 6 different b-values (0, 50, 100, 150, 200, and 1000 seconds/mm2). From the intravoxel incoherent motion MR imaging data, diffusion coefficient, perfusion fraction, and pseudodiffusion coefficient maps were obtained using a 2-step fitting algorithm based on the Levenberg-Marquardt method. The presence of decreases in the intravoxel incoherent motion perfusion fraction and pseudodiffusion coefficient values compared with the contralateral normal-appearing brain was graded on a 2-point scale by 2 independent neuroradiologists. Interobserver agreement on the rating scale was evaluated using the κ statistic. Clinical characteristics of patients with a nondecreased intravoxel incoherent motion perfusion fraction and/or pseudodiffusion coefficient rated by the 2 observers were also assessed. RESULTS Interobserver agreement was shown for the intravoxel incoherent motion perfusion fraction (κ = 0.854) and pseudodiffusion coefficient (κ = 0.789) maps, which indicated almost perfect and substantial agreement, respectively. Patients with a nondecreased intravoxel incoherent motion perfusion fraction tended to show recanalization of the occluded intracranial arteries more frequently than patients with a decreased intravoxel incoherent motion perfusion fraction. CONCLUSIONS Intravoxel incoherent motion MR imaging could be performed in < 1 minute in addition to routine DWI. Intravoxel incoherent motion parameters noninvasively provide feasible, qualitative perfusion-related information for assessing patients with acute ischemic stroke.

Abstract
Abstract
Background
There is growing awareness of polypharmacy as a global issue. Several countries have introduced policies to optimize multidrug prescriptions. In Japan, hospital prescription fee “F100” and outpatient prescription fee “F400” have been instituted to promote the correct use of drugs, the medical treatment fee is restricted when seven or more types of drugs are prescribed. However, non-polypharmacy patients who need multiple drugs are also comprehensively evaluated within the purview of the same drug insurance claim criteria. Thus, the current state of such policies is still unclear. This study identified the age group in which drug claims have changed based on drug insurance claim criteria and elucidated the relationship between policy interventions and multidrug prescriptions.
Methods
We analyzed F100 and F400 cases using open data from the National Database of Health Insurance Claims and Specific Health Checkups of Japan from April 2015 to March 2017. These sources include a population of about 69 million patients. Moreover, the growth rate of the number of patients who were prescribed seven or more types of drugs was evaluated.
Results
F100 prescription claims decreased by − 12.7% (n = 3,239,070) in 2016 as compared to 2015 (n = 3,700,396), and the number of F400 prescription claims decreased by − 7.7% (n = 28,745,468) in 2016 as compared to 2015 (n = 31,142,484), for seven or more types of drugs. The drug insurance claim rate among people over the age of 65 was 74.2% to F100 and 77.9% to F400, and this age group represented the highest proportion among all age groups.
Conclusions
The rate of health insurance claims for multidrug prescriptions clearly decreased after the institution of policy interventions to optimize the use of seven or more types of drugs. The present study suggests that the prescription fee restriction could reduce the rate of multidrug prescriptions and consequent decreases the risk of adverse drug-related events in polypharmacy patients.
Key messages
Policy interventions related to the optimization of drug prescriptions encourage behavioral factors of healthcare providers. Polypharmacy treatment must be established through prescriptions information linkage between clinical practices and community.

Abstract
A 4-year-old male Japanese Shiba Inu presented with recurrent chylothorax. The thoracic duct was successfully imaged using computed tomography after the injection of an iodine contrast agent into the subcutaneous tissue surrounding the anus. The thoracic duct was successfully ligated and pericardectomy performed via an open thoracotomy. Pleural effusion improved but relapsed a week after the surgery. A second lymphography revealed a collateral thoracic duct that was not detected during the first lymphography. The collateral duct was ligated and chylothorax was resolved after the second surgery. The lymphography applied in this study was minimally-invasive and easily provided images of the thoracic duct in a dog with chylothorax.

Abstract
We studied 135 hands in 77 Japanese patients to assess the frequency of radial involvement and its association with recurrence and the Dupuytren’s diathesis. The radial aspect of the hand was affected in 22% of the hands. Diseased cords were observed in ten patients who underwent surgery on the radial aspect of the hand. Longitudinal cords on the radial side of thenar eminence and distal transverse interdigital cords were common. The radial aspect of the hand was the most common site of disease extension, though recurrence never occurred after excision of a radial lesion. Ectopic lesions, bilateral hand involvement, and recurrence were significantly more frequent in patients with the radial side involvement. Thus the results of this study suggest that radial side disease is associated with the Dupuytren’s diathesis and is a risk factor of recurrence.

Abstract
Introduction Therapeutic strategies for intramural hematoma (IMH) involving the ascending aorta remain controversial. Report The patient was a 72 year old woman with a history of chest pain. Multidetector computed tomography (MDCT) showed an IMH involving the ascending aorta. Because virtual angioscopy revealed a punctate intimal tear in the ascending aorta, acute aortic dissection with an intimal tear and not IMH was diagnosed, and emergency surgery was performed. The post-operative course was uneventful. Discussion Virtual angioscopy allows the vascular lumen to be examined minimally invasively on the basis of images reconstructed from MDCT data. Even if MDCT does not clearly show an intimal tear associated with aortic dissection in a general view, virtual angioscopy can show the exact location and size of the tear before surgery. Virtual angioscopy is very useful for distinguishing thrombosed-type acute aortic dissection without clear ulcer like projections from an IMH, which may facilitate therapeutic planning.

Abstract
BACKGROUND The purpose of this study was to investigate the usefulness of a hydrocolloid dressing containing ceramide for hand-foot skin reaction (HFSR) on the soles of the feet in metastatic renal cell carcinoma (RCC) patients treated with sorafenib. PATIENTS AND METHODS Patients with grade 1 HFSR on the soles of the feet were randomly assigned in to two groups. One group received a hydrocolloid dressing containing ceramide (arm A) and the other received 10% urea cream (arm B). Patients in both groups applied treatment to the affected sites on the soles of the feet, but not to the hands. The primary end point was the incidence of grade 2 or 3 HFSR on the soles of the feet in the first 4 weeks. RESULTS Thirty-three patients were assessed (17 in arm A and 16 in arm B), and there were no significant differences in baseline characteristics between the two groups. During the observation period of this study, grade 2 or 3 HFSR on the soles of the feet was found in 29% of patients in arm A and was significantly less than the 69% in arm B (P=0.03). The incidence of HFSR on the hands, however, was similar in both arms. The median time to grade 2 or 3 HFSR on the soles of the feet was also significantly longer in arm A than in arm B (P=0.03). CONCLUSIONS These results indicate that a hydrocolloid dressing containing ceramide prevented the worsening of HFSR caused by sorafenib in metastatic RCC patients.

Abstract
OBJECTIVES The aim of this study was to evaluate the characteristic power Doppler sonographic images of buccal space tumorous and non-tumorous lesions. METHODS 48 patients with buccal space lesions were evaluated with greyscale sonography followed by power Doppler sonography with a 12 MHz linear transducer. On greyscale sonography, buccal space lesions were assessed for the boundary (clear or unclear), echogenicity (hypoechoic or isoechoic) and internal architecture (homogeneous or heterogeneous). Power Doppler sonography was performed to evaluate the vascular signals within the buccal space lesions. RESULTS 48 lesions were found in the 48 patients; of these 48 lesions, 28 were tumourous and 20 were non-tumourous. In the 28 tumours, 15 cases showed clear boundaries, 15 cases were hypoechoic relative to adjacent tissues and 22 cases presented with a heterogeneous appearance on greyscale sonography. The internal vascularity of 19 tumours was shown using power Doppler sonography. In the 20 non-tumorous lesions, 11 cases showed clear boundaries, 17 cases were hypoechoic relative to adjacent tissues and 13 cases presented with a homogeneous appearance on greyscale sonography. 18 non-tumorous lesions showed no internal vascularity using power Doppler sonography. Logistic multivariate regression analysis between the tumour group and the non-tumorous lesions group demonstrated that the internal architecture (odds ratio = 8.270, p = 0.029) and vascular signals (odds ratio = 17.533, p = 0.003) were significant variables. CONCLUSIONS Power Doppler sonography is a useful technique for the differential diagnosis of tumorous and non-tumorous buccal space lesions.

Abstract
INTRODUCTION We report herein a new method of transumbilical laparoscopic surgery using a GelPort through an umbilical zigzag skin incision. The method involves collaborating with plastic surgeons to ensure the procedure was minimally invasive. MATERIALS AND SURGICAL TECHNIQUE After marking a zigzag skin incision in the umbilical region, the skin was incised along this line. Then, a GelPort double-ring wound retractor was inserted through the incision, which enlarged the diameter of the fascial opening to 6 cm. The Gelport was latched on the wound retractor ring, following the inflation of the pneumoperitoneum by CO (2). One or more additional ports were inserted as necessary. All operations were performed in the standard fashion. The specimen was easily extracted from the abdomen through the umbilical incision, and anastomosis was performed. Using the above method, we performed the following procedures: one total gastrectomy, one distal gastrectomy, three gastric local resections, five right hemicolectomies, two high anterior resections, three cholecystectomies, and seven transabdominal preperitoneal hernioplasties. All cases were accomplished without any complications using this method. The wounds of the umbilical region were almost "scarless" in all cases. DISCUSSION We developed an umbilical zigzag skin incision technique to perform abdominal laparoscopic operations using a GelPort, with a minimal number of skin incisions. We consider that our method reduces the technical difficulties associated with laparoscopic surgery and maintains cosmesis.

Abstract
OBJECTIVE To identify a new genetic cause of distal hereditary motor neuropathy (dHMN), which is also known as a variant of Charcot-Marie-Tooth disease (CMT), in a Chinese family. METHODS We investigated a Chinese family with dHMN clinically, electrophysiologically, and genetically. We screened for the mutations of 28 CMT or related pathogenic genes using an originally designed microarray resequencing DNA chip. RESULTS Investigation of the family history revealed an autosomal dominant transmission pattern. The clinical features of the family included mild weakness and wasting of the distal muscles of the lower limb and foot deformity, without clinical sensory involvement. Electrophysiologic studies revealed motor neuropathy. MRI of the lower limbs showed accentuated fatty infiltration of the gastrocnemius and vastus lateralis muscles. All 4 affected family members had a heterozygous missense mutation c.2677G>A (p.D893N) of alanyl-tRNA synthetase (AARS), which was not found in the 4 unaffected members and control subjects. CONCLUSION An AARS mutation caused dHMN in a Chinese family. AARS mutations result in not only a CMT phenotype but also a dHMN phenotype.

Abstract
OBJECTIVE To investigate the outcome of Japanese anorexia nervosa (AN) patients who were treated with the standard Japanese inpatient therapy. METHOD Of the 88 female AN patients treated with our inpatient therapy between January 1997 and December 2002, 67 (76.1%) who agreed to cooperate in this study were assessed by the Global Clinical Score (GCS) at admission and follow-up, 6.3±1.8 years after discharge. Their clinical characteristics at admission and discharge were also examined. RESULTS Four (6.0%) patients had died before follow-up. BMI was significantly increased during inpatient therapy. At follow-up, excellent, much improved, symptomatic, and poor outcomes on GCS were 57.1%, 14.3%, 14.3% and 14.3%, respectively. Younger age at admission and larger BMI at discharge were significantly associated with a better outcome. DISCUSSION This study shows the potential for the use of this method for the treatment of AN patients in countries without specialized eating disorder units.

Abstract
INTRODUCTION We report herein a new method of transumbilical laparoscopic surgery using a GelPort through an umbilical zigzag skin incision. The method involves collaborating with plastic surgeons to ensure the procedure was minimally invasive. MATERIALS AND SURGICAL TECHNIQUE After marking a zigzag skin incision in the umbilical region, the skin was incised along this line. Then, a GelPort double-ring wound retractor was inserted through the incision, which enlarged the diameter of the fascial opening to 6 cm. The Gelport was latched on the wound retractor ring, following the inflation of the pneumoperitoneum by CO (2). One or more additional ports were inserted as necessary. All operations were performed in the standard fashion. The specimen was easily extracted from the abdomen through the umbilical incision, and anastomosis was performed. Using the above method, we performed the following procedures: one total gastrectomy, one distal gastrectomy, three gastric local resections, five right hemicolectomies, two high anterior resections, three cholecystectomies, and seven transabdominal preperitoneal hernioplasties. All cases were accomplished without any complications using this method. The wounds of the umbilical region were almost "scarless" in all cases. DISCUSSION We developed an umbilical zigzag skin incision technique to perform abdominal laparoscopic operations using a GelPort, with a minimal number of skin incisions. We consider that our method reduces the technical difficulties associated with laparoscopic surgery and maintains cosmesis.

Abstract
OBJECTIVE The aim of this study was to assess the genetic effects of the vascular endothelial growth factor (VEGF) pathway on retinopathy of prematurity (ROP). STUDY DESIGN A prospective study from a tertiary center that enrolled 204 Japanese infants (<35 weeks of gestational age (GA)) having no anomalies. ROP developed in 127, but not in 77 infants. The relative severity was defined as non-severe, moderate and severe ROP for GA, based on the staging criteria. VEGF (g.-634G>C, g.+13553C>T) and VEGF-receptor (KDR g.+4422(AC)11 to 14, Flt-1 c.+6724(TG)13 to 23) gene polymorphisms and clinical variables were assessed by uni/multivariate analyses. RESULT The frequency of polymorphisms did not differ between ROP and non-ROP patients. The TT genotype of g.+13553 showed a higher odds ratio for non-severe ROP than CC genotype (P=0.006). Multivariate analyses indicated that low birth weight, blood transfusion and respiratory distress syndrome, but not polymorphisms, were the risk factors of advanced ROP (≥ stage 3). CONCLUSION A genotype of the VEGF pathway weakly affects the severity of ROP compared with other clinical factors.

Abstract
OBJECTIVES Our aim was to determine whether ablated liver parenchyma surrounding a tumour can be assessed by MRI with ferucarbotran administered prior to radiofrequency ablation (RFA) compared with enhanced CT. METHODS 55 hepatocellular carcinomas (HCCs) in 42 patients and 5 metastatic liver cancers in 3 patients were treated by RFA after ferucarbotran administration. We then performed T(2)* weighted MRI after 1 week and enhanced CT after 1 month. T(2)* weighted MRI demonstrated the ablated parenchyma as a low-intensity rim around the high intensity of the ablated tumour in these cases. The assessment was allocated to one of three grades: margin (+), high-intensity area with continuous low-intensity rim; margin zero, high-intensity area with discontinuous low-intensity rim; and margin (-), high-intensity area extending beyond the low-intensity rim. RESULTS Margin (+), margin zero and margin (-) were found in 17, 35 and 5 nodules, respectively. All 17 nodules with margin (+) and 13 of those with margin zero were assessed as having sufficient ablative margins on CT. The remaining 22 nodules with margin zero had insufficient margins on CT. The overall agreement between MRI and CT for the diagnosis of the ablative margin was moderate (κ = 0.507, p < 0.001). No local recurrence was found in 15 HCC nodules with margin (+), whereas local recurrence was found in 4 (11.8%) out of 34 HCC nodules with margin zero. CONCLUSION Administration of ferucarbotran before RFA enables the ablative margin to be visualised as a low-intensity rim, and also enables the evaluation of the ablative margin to be made earlier and more easily than with enhanced CT.

Abstract
571 Background: Capecitabine was approved in Japan in 2007 for the adjuvant treatment of stage III colon cancer based on Japanese clinical trial data in advanced and recurrent colorectal and breast cancers as well as data from the Phase III X-ACT trial. For the current study, we aimed to clarify compliance and tolerability of adjuvant treatment with capecitabine in Japanese patients. The study was entered in the UMIN clinical trial registry (UMIN000001444) by the Kyushu Study Group of Clinical Cancer (KSCC). Ethical approval was granted by the institutional review board of each hospital involved. Methods: Based on completion rates from the X-ACT trial we enrolled 97 patients with R0 stage III colon cancer who had histologically confirmed disease and had undergone curative resection (3D2 lymph node dissection). Patients were given oral capecitabine therapy (2,500 mg/m2/day; days 1–14 q3w; eight cycles) within 8 weeks of surgery. The proportion of patients completing eight cycles of treatment per protocol was the primary endpoint, and adverse event (AE) rate was analyzed as a secondary endpoint. Results: Treatment completion in the total patient population was 66.0% (64/97 patients; 95% CI: 55.7–75.3%) and in the per protocol population (PPP) was 70.3% (64/91; 95% CI: 59.8–79.5%). AEs leading to treatment discontinuation included hand-foot syndrome (HFS; n=7), hematotoxicity (n=5) and increased hepatic activity (n=4). Grade 3/4 AEs of note included HFS (22.7%), neutropenia (7.2%), diarrhea (2.1%), and increased bilirubin (0.0%). Of note, any treatment delay >3 weeks in the current trial was considered a withdrawal. In the X-ACT trial, delays of any duration were permitted. Using the X-ACT criteria the completion rate for the PPP in this study was 80.2%, comparable to the figure reported in X-ACT. Conclusions: Our results confirm those of previous global phase III studies and show that capecitabine is well tolerated in both global and Japanese-only populations, with similar high completion rates in both.
