Abstract
INTRODUCTION Every dental provider needs to be educated about medical emergencies to provide safe dental care. Simulation training is available with simulators such as advanced life support manikins and robot patients. However, the purchase and development costs of these simulators are high. We have developed a simulation training course on medical emergencies using an inexpensive software application. The purpose of this study was to evaluate the educational effectiveness of this course. MATERIALS AND METHODS Fifty-one dental providers participated in this study from December 2014 to March 2015. Medical simulation software was used to simulate a patient's vital signs. We evaluated participants' ability to diagnose and treat vasovagal syncope or anaphylaxis with an evaluation sheet and conducted a questionnaire before and after the scenario-based simulation training. RESULTS The median evaluation sheet score for vasovagal syncope increased significantly from 7/9 before to 9/9 after simulation training. The median score for anaphylaxis also increased significantly from 8/12 to 12/12 (P < .01). For the item "I can treat vasovagal syncope/anaphylaxis adequately," the percentage responding "Strongly agree" or "Agree" increased from 14% to 56% for vasovagal syncope and from 6% to 42% for anaphylaxis with simulation training. CONCLUSIONS This simulation course improved participants' ability to diagnose and treat medical emergencies and improved their confidence. This course can be offered inexpensively using a software application.

Abstract
An 83-year-old woman was admitted to our hospital because of a space-occupying lesion (SOL) in the liver. Enhanced computed tomography (CT) showed a nodule measuring 20mm in size in the posterosuperior segment of the right hepatic lobe (S7) and another nodule measuring 14mm in size in the anterosuperior segment of the right hepatic lobe (S8). The margins of these nodules showed faint enhancement in the arterial phase and presented as low-density areas in the equilibrium phase. The S8 SOL could not be easily identified using ultrasonography (US). However, the S7 SOL could be clearly identified as a nodule accompanying the marginal enhancement in the early vascular phase and a defect in the late vascular phase using contrast-enhanced US. On gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging, both nodules were described as low-intensity lesions in the T1 phase, high-intensity lesions in the T2 phase, faint high-intensity diffusion-weighted images, and clear low-intensity lesions in the hepatobiliary phase. On positron-emission CT, there was no uptake of 18F-fluorodeoxyglucose in these nodules. Hepatectomy was performed because we were unable to rule out a malignant tumor. Histopathologically, these lesions demonstrated collapsed vascular spaces against a background of rich paucicellular fibrous stroma and were diagnosed as sclerosed hemangiomas. The occurrence of multiple sclerosed hemangiomas is rare and often difficult to diagnose because of variable findings on imaging studies. We report a case of multiple hepatic sclerosed hemangiomas, which was difficult to diagnose preoperatively. Moreover, we have reviewed the literature, particularly with respect to the relevant imaging findings.

Abstract
Tissue engineering is a promising method for the regeneration of oral and maxillofacial tissues. Proper selection of a cell source is important for the desired application. This review describes the discovery and usefulness of dedifferentiated fat (DFAT) cells as a cell source for tissue engineering. Dedifferentiated Fat cells are a highly homogeneous cell population (high purity), highly proliferative, and possess a multilineage potential for differentiation into various cell types under proper in vitro inducing conditions and in vivo. Moreover, DFAT cells have a higher differentiation capability of becoming osteoblasts, chondrocytes, and adipocytes than do bone marrow-derived mesenchymal stem cells and/or adipose tissue-derived stem cells. The usefulness of DFAT cells in vivo for periodontal tissue, bone, peripheral nerve, muscle, cartilage, and fat tissue regeneration was reported. Dedifferentiated Fat cells obtained from the human buccal fat pad (BFP) are a minimally invasive procedure with limited esthetic complications for patients. The BFP is a convenient and accessible anatomical site to harvest DFAT cells for dentists and oral surgeons, and thus is a promising cell source for oral and maxillofacial tissue engineering.

Abstract
BACKGROUND In Japan, daclatasvir (DCV) and asunaprevir (ASV) therapy was the first IFN-free treatment to be approved, and thousands of patients have since been successfully treated, with an SVR rate of around 90%. The converse, however, is that around 10% of patients fail to achieve viral eradication and must be retreated using a different approach. This study is to evaluate treatment efficacy of ledipasvir/sofosbuvir and ribavirin in patients who failed to respond to DCV and ASV therapy. METHODS Thirty patients were treated with 12 weeks of ledipasvir/sofosbuvir and ribavirin. We evaluated the rate of sustained virological response 12 weeks after the end of treatment (SVR12) and examined the incidence of adverse events during ledipasvir/sofosbuvir and ribavirin treatment. NS5A and NS5B resistance-associated variants (RAVs) in treatment failure cases were examined. RESULTS The overall SVR12 rate was 86.7% (26/30). Large decreases in mean log10 HCV RNA levels were observed in patients without cirrhosis, and the SVR12 rate for these patients was 100% (12/12). In cases of cirrhosis, SVR12 rate was 72.2% (13/18). The common factors in treatment failure cases were the presence of liver cirrhosis and both NS5A L31M/I and Y93H RAVs. The frequency of RAVs did not change before and after treatment among patients who relapsed. CONCLUSION Ledipasvir/sofosbuvir with ribavirin is an effective retreatment option for patients with chronic hepatitis C who failed to respond to prior daclatasvir and asunaprevir therapy.

Abstract
Abstract
Background:
When multiple radioactive sentinel lymph nodes (SLNs) are present during sentinel lymph node biopsy (SLNB), excision of those SLNs with >10% radioactive count per minute (high-CPM) of the most radioactive node (“10% rule”) has been proposed. Although this “10% rule” may avoid excessive removal of SLNs,the risk of false negative and remnant positive SLNs in the patients who have SLNs with <10% CPM (low-CPM) remain unclear. The purpose of this analysis is to determine the clinical validity of this “10% rule” for early breast cancer patients.
Method:
We reviewed the records of successful SLNBs using the radioisotope (RI) method performed between January 2001 and December 2016 in our institution. The radioactive count from each excised SLN was measured. Non-radioactive lymph nodes were excluded from this analysis. All SLNs were pathologically assessed by 2mm serial section with hematoxylin and eosin staining.
Results:
In the 3,043 patients with successful SLNB,the median number of radioactive SLNs removed was 2 (mean, 1.8; range, 1-10) and 599 patients (19.7%) had SLNs with low-CPM. The total number of radioactive SLNs was 5,472, and 875 (16.0%) out of 5,472 SLNs were low-CPM. Sixty-one (7.0%) out of these 875 SLNs with low CPM in 56 patients (1.8%) had metastatic disease by pathological assessment. The number of metastatic SLN with low-CPM was one in 51 patients and two in 5 patients. Nineteen patients (0.6%) had no metastatic lesion in SLNs with high-CPM.
Discussion and Conclusions:
If SLNB was performed by RI method alone with “10% rule”, false negative rate increased by 0.6% and underestimation increased up to 1.8%. Furthermore, 19.7% of the patients have the benefit of avoiding excessive removal of SLNs.Considering the risk and benefit, “10% rule” is a high validitymethod to capture metastatic SLNs even in the setting that ALND will not be performed.

Abstract
BACKGROUND Previously, the mucosal histology in achalasia has only been investigated using superficial biopsy or surgically resected esophageal specimens in end-stage cases. We investigated the histology of the full-layer mucosa in early and advanced achalasia. METHODS Endoscopy was performed for the pinstripe pattern (PSP) (an early achalasia indicator) and dilation and thickening of the mucosa (advanced achalasia indicators). A mucosal entry site for peroral endoscopic myotomy was created using cap-fitted endoscopic mucosal resection to access the full-layer mucosa and the submucosa. KEY RESULTS Mucosal histology was compared between 32 patients with achalasia and 15 controls. Histological esophagitis with findings of inflammatory cell infiltration and dilated intercellular spaces was observed more in patients with achalasia than in controls (87.5% vs 13.3%, P<.001; 84.4% vs 46.7%, P=.049). Muscularis mucosae (MM) atrophy and epithelial wave were only observed in achalasia (40.6% vs 0%, P=.005; 28.1% vs 0%, P=.043). Fibrosis was more common in achalasia, but without statistical significance (31.3% vs 20.0%, P=.503). In achalasia with endoscopic dilation and thickening of the mucosa, MM atrophy was observed histologically, and in cases involving endoscopic PSP, the histological epithelial wave was observed. CONCLUSIONS & INFERENCES Histological findings of esophagitis were observed endoscopically even in early achalasia. Pinstripe pattern corresponds to the epithelial wave observed histologically in achalasia, whereas endoscopic findings in advanced achalasia correspond to MM atrophy. Appropriate management is necessary during early achalasia to prevent progression to advanced achalasia with more severe histological changes.

Abstract
This study examined the aging effect on disuse muscle atrophy prevention using heat stress. Wistar rats aged 7 and 60 weeks were divided into three groups as follows: control, immobilized (Im), and immobilized and heat stressed (ImH). Heat stress was given by immersing the hindlimbs in hot water (42 °C) for 60 min, once in every 3 days and the gastrocnemius (GAS) and soleus (SOL) muscles were extracted after 14 days. Muscle-fiber types were classified using ATPase staining. Heat shock protein 70 (HSP70) was assessed through Western blotting. In GAS muscle of both groups and SOL muscle of 7-week-old rats, the fiber diameter of each muscle type in the ImH group significantly increased compared with that in the Im group. However, this could not be observed in the SOL muscle of the 60-week-old rats. The increased percentage of type-I fibers and variability of types I and II muscle-fiber diameter were evident in the SOL muscle of the 60-week rats. HSP70 was significantly elevated in the ImH group compared with in the Im group in both muscle types of both age groups. Thus, effectiveness of heat stress in the prevention of disuse muscle atrophy appears unsatisfactory in aging muscle fibers.

Abstract
The effect of endoscopic submucosal dissection (ESD) on esophageal motility remains unknown. Therefore, the aim of this study is to elucidate changes in esophageal motility after ESD along with the cause of dysphagia using high-resolution manometry (HRM). This is a before-and-after trial of the effect of ESD on the esophageal motility. Twenty patients who underwent ESD for superficial esophageal carcinoma were enrolled in this study. Patients filled out a questionnaire about dysphagia and underwent HRM before and after ESD. Results before and after ESD were compared. Data were obtained from 19 patients. The number of patients who complained of dysphagia before and after ESD was 1/19 (5.3%) and 6/19 (31.6%), respectively (P = 0.131). Scores from the five-point Likert scale before and after ESD were 0.1 ± 0.5 and 1.0 ± 1.6, respectively (P = 0.043). The distal contractile integral (DCI) before and after ESD and the number of failed, weak, or fragmented contractions were not significantly different. However, in five patients with circumferential ESD, DCI was remarkably decreased and the frequency of fail, weak, or fragmented contractions increased. Univariate regression analysis showed a relatively strong inverse correlation of ΔDCI with the circumferential mucosal defect ratio {P < 0.01, standardized regression coefficient (r) = -0.65}, the number of stricture preventions (P < 0.01, r = -0.601), and the number of stricture resolutions (P < 0.01, r = -0.77). This HRM study showed that impairment of esophageal motility could be caused by ESD. The impairment of esophageal motility was conspicuous, especially in patients with circumferential ESD and subsequent procedures such as endoscopic triamcinolone injection and endoscopic balloon dilatation. Impaired esophageal motility after ESD might explain dysphagia.

Abstract
AIMS We retrospectively analyzed the clinical outcome and prognostic parameters in patients with hepatocellular carcinoma (HCC) and bone metastases who had received treatment with zoledronic acid (ZOL). METHODS Ninety-nine HCC patients with bone metastases who had been treated with ZOL were enrolled in this retrospective cohort study. We analyzed the prognostic factors, including serum N-telopeptide of type I collagen (NTX) levels, as bone metabolism markers. RESULTS The median overall survival (OS) time was 11.5 months. Child-Pugh grade A (P = 0.004) and intrahepatic tumor stage (IHTS) T0-3 (P = 0.010) correlated significantly with favorable OS. In 46 patients with grade A and T0-3, receiver operating characteristic curve analysis defined 16 nmol BCE/L serum NTX as the cut-off level for median OS. Multivariate analysis identified baseline serum NTX <16 nmol BCE/L (P = 0.045) as the only significant and independent determinant of OS. CONCLUSION Low baseline serum NTX level correlated with favorable outcome in bone metastatic HCC patients with Child-Pugh grade A and IHTS T0-3 treated with ZOL.

Objective This study examined the association between sudden natural death and abdominal fat using postmortem computed tomography (CT) scans. Subjects and methods Postmortem CT images at the umbilical level of 241 subjects were used to measure abdominal areas of subcutaneous‐ and visceral fat, the rate of visceral fat and the waist circumference. Of the study subjects, 174 died of sudden natural death (130 men and 44 women), and 67 died of different causes (46 men and 21 women). All were between 40 and 75 years of age. Logistic regression analysis was performed to identify independent abdominal parameters associated with sudden natural death. Results By univariate analysis, the areas of subcutaneous and visceral fat were significantly larger in sudden natural death than who died of different causes (subcutaneous fat, odds ratio [OR] = 1.004, 95% confidence interval [CI] = 1.000–1.007, p = 0.03; visceral fat, OR = 1.008, 95% CI = 1.003–1.013, p < 0.01). Multivariate analysis showed that the area of visceral fat was an independent factor associated with the risk of sudden natural death (OR = 1.008, 95% CI = 1.002–1.015, p = 0.02). Conclusions Postmortem CT revealed that sudden natural death was related to abdominal fat deposits.

IFNL4 polymorphism effects on outcome of simeprevir, peginterferon, and ribavirin therapy for older patients with genotype 1 chronic hepatitis C. Hepatol Res 2017; 47:E5-E13. [PMID: 27027531 DOI: 10.1111/hepr.12715] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2016] [Revised: 03/09/2016] [Accepted: 03/25/2016] [Indexed: 12/17/2022]
Abstract
AIM Older patients with chronic hepatitis C have a lower virological response to interferon (IFN)-based treatments compared to younger patients. A single nucleotide polymorphism in the IFN-λ-4 (IFNL4) gene has a potent predictive effect on treatment response to IFN-based treatments. The efficacy of simeprevir (SMV) plus pegylated-IFN (PEG-IFN) and ribavirin therapy and the predictive value of IFNL4 on the outcome of therapy for older patients have not been addressed. METHODS This retrospective multicenter study included 234 consecutive Japanese patients with genotype 1 chronic hepatitis C. We assessed the predictive factors for sustained virological response (SVR) to SMV, PEG-IFN, and ribavirin triple therapy in 170 younger (<70 years) and 64 older (≥70 years) patients. IFNL4 polymorphism ss469415590 was analyzed by Invader assay. RESULTS The SVR rate for older patients was similar to that for younger patients (63.9% and 72.0%, respectively). The SVR rate for the IFNL4 TT/TT group was significantly higher than the IFNL4 TT/ΔG or ΔG/ΔG group both in younger (93.6% and 46.1%, respectively, P < 0.01) and older patients (84.4% and 33.3%, respectively, P < 0.001). In multivariate regression analysis, IFNL4 TT/TT genotype, response to previous treatment and IFNL4 TT/TT genotype were identified as independent predictive factors for SVR in older and younger patients, respectively. Decrease in hemoglobin level was similar between the two groups. CONCLUSION The virological response to SMV triple therapy in older patients was similar to that of younger patients. Analysis of IFNL4 polymorphisms is a valuable predictor in both younger and older patients.

Abstract
An 84-year-old woman was hospitalized due to consciousness disorder as hyperammonemia. She had no etiology of liver disease. Twelve months before the current admission, she had been diagnosed with dementia based on her low level of daily perception and physical activity. Abdominal computed tomography revealed a large portosystemic shunt between the medial branch of the portal vein and middle hepatic vein. After the improvement of her consciousness disturbance by medical treatment, percutaneous shunt embolization was electively performed. The patient showed a remarkable clinical improvement. Consciousness disturbance caused by hyper-ammonemia might be underlying in dementia patients. Increase of hepatopetal portal blood flow might have contributed to the improvement of her consciousness disturbance. Embolization of the portosystemic shunt might be more effective for patients without liver disease as in the present case.
