Purpose: The aim of this study is to assess the value of adaptive statistical iterative reconstruction (ASIR) and model-based iterative reconstruction (MBIR) for reduction of metal artifacts due to dental hardware in carotid CT angiography (CTA). Methods: Thirty-seven patients with dental hardware who underwent carotid CTA were included. CTA was performed with a GE Discovery CT750 HD scanner and reconstructed with filtered back projection (FBP), ASIR, and MBIR. We measured the standard deviation at the cervical segment of the internal carotid artery that was affected most by dental metal artifacts (SD1) and the standard deviation at the common carotid artery that was not affected by the artifact (SD2). We calculated the artifact index (AI) as follows: AI = [(SD1)2 − (SD2)2]1/2 and compared each AI for FBP, ASIR, and MBIR. Visual assessment of the internal carotid artery was also performed by two neuroradiologists using a five-point scale for each axial and reconstructed sagittal image. The inter-observer agreement was analyzed using weighted kappa analysis. Results: MBIR significantly improved AI compared with FBP and ASIR (p < 0.001, each). We found no significant difference in AI between FBP and ASIR (p = 0.502). The visual score of MBIR was significantly better than those of FBP and ASIR (p < 0.001, each), whereas the scores of ASIR were the same as those of FBP. Kappa values indicated good inter-observer agreements in all reconstructed images (0.747–0.778). Conclusions: MBIR resulted in a significant reduction in artifact from dental hardware in carotid CTA. © 2017, Springer-Verlag Berlin Heidelberg.

Background & Aims Roles of alcohol consumption in non-alcoholic fatty liver disease are still controversial, although several cross-sectional studies have suggested the beneficial effect of light to moderate drinking on fatty liver. We analyzed the longitudinal relationship between drinking pattern and fatty liver. Methods We included 5297 Japanese individuals (3773 men and 1524 women) who underwent a baseline study in 2003 and follow-up at least once from 2004 to 2006. Generalized estimating equation was used to estimate any association between drinking pattern and fatty liver assessed by ultrasonography. Results At baseline, 1179 men (31.2%) and 235 women (15.4%) had fatty liver; 2802 men (74.2%) and 436 women (28.6%) reported alcohol consumption. At the latest follow-up, 348 of 2594 men (13.4%) and 101 of 1289 women (7.8%) had newly developed fatty liver; 285 of 1179 men (24.2%) and 70 of 235 women (29.8%) demonstrated a remission of fatty liver. In men, drinking 0.1-69.9 g/week (odds ratio, 0.79 [95% confidence interval, 0.68-0.90]), drinking 70.0-139.9 g/week (0.73 [0.63-0.84]), drinking 140.0-279.9 g/week (0.69 [0.60-0.79]), and drinking ≥280.0 g/week (0.68 [0.58-0.79]) were inversely associated with fatty liver after adjusting for obesity, exercise, and smoking. In women, drinking 0.1-69.9 g/week (0.71 [0.52-0.96]) and drinking 70.0-139.9 g/week (0.67 [0.45-0.98]) were inversely associated with fatty liver after the adjustment. Conclusions Light to moderate alcohol consumption, or even somewhat excessive amounts especially in men, was likely to protect most individuals against fatty liver over time.

Early predictors of status epilepticus (SE)-associated mortality and morbidity have not been systematically studied in children, considerably impeding the identification of patients at risk.To determine reliable early predictors of SE-associated mortality and morbidity and identify the etiology of SE-associated sequelae in Japanese children.We conducted a prospective multicenter study of clinical findings and initial laboratory data acquired at SE onset, and assessed outcomes at the last follow-up examination. In-hospital death during the acute period and neurological sequelae were classified as poor outcomes.Of the 201 children who experienced their first SE episode, 16 exhibited poor outcome that was most commonly associated with acute encephalopathy. Univariate analysis revealed that the following were associated with poor outcomes: young age (24 months); seizure duration >90 min; seizure intractability (failure of the second anticonvulsive drug); biphasic seizures; abnormal blood glucose levels (<61 or >250 mg/dL); serum aspartate aminotransferase (AST) 56 U/L; and C-reactive protein (CRP) levels >2.00 mg/dL. Multivariate analysis revealed that young age, seizure intractability, abnormal blood glucose levels, and elevated AST and CRP levels were statistically significant.Young age and seizure intractability were highly predictive of poor outcomes in pediatric SE. Moreover, abnormal blood glucose levels and elevated AST and CRP levels were predictors that might be closely associated with the etiology, especially acute encephalopathy and severe bacterial infection (sepsis and meningitis) in Japanese children.

Background: The characteristics of symptoms reported by elderly patients with gastroesophageal reflux disease (GERD) have not been fully investigated. We performed this study to clarify these characteristics in elderly patients with GERD. Methods: The study subjects were 340 Japanese patients with symptoms of heartburn and/or acid regurgitation. All patients were investigated by upper gastrointestinal endoscopy, and were asked about the presence of atypical GERD symptoms, such as an epigastric burning sensation, epigastralgia, epigastric discomfort, and abdominal fullness, as well as the time of day when bothersome symptoms occurred. Results: Of the 340 patients, 161 were elderly (≥65 years old) and 179 were non-elderly (age<65 years). There were 158 patients without esophageal mucosal breaks, 147 with low-grade reflux esophagitis (RE; Los Angeles classification grade A or B), and 35 with high-grade reflux esoph-agitis (LA grade C or D). Elderly patients with RE reported typical reflux symptoms at the same frequency as the non-elderly patients, whereas elderly patients without mucosal breaks reported typical symptoms more frequently than the non-elderly patients without mucosal breaks. Both elderly and non-elderly patients with different types of GERD reported that their symptoms occurred most frequently during the postprandial period. Conclusion: Elderly patients with GERD tend to show typical GERD symptoms frequently at the typical postprandial time points in a day, irrespective of the presence of esophageal mucosal breaks. © Springer 2011.

Castleman's disease, an uncommon lymphoproliferative disorder, can be difficult to differentiate from immunoglobulin (Ig) G4-related disease. The latter is typically characterized by elevated serum IgG4 levels and abundant IgG4-positive cells. However, multicentric Castleman's disease can also have elevated serum IgG4 levels and even fulfill the histological diagnostic criteria for IgG4-related disease. We present a case of cutaneous multicentric Castleman's disease mimicking IgG4-related disease. A 55-year-old Japanese woman developed erythematous and brown plaques on her back. Skin biopsy revealed regressive follicles with interfollicular plasmacytosis, and many plasma cells were positive for IgG4 (mean 263.67. ± 79.19, range 214-355 per high power field). The IgG4-/IgG-positive cell ratios were 35.6%, 36.2%, and 48.4%, respectively, with an average of 40.6%, thus fulfilling the histological diagnostic criteria for IgG4-related disease. Furthermore, serum IgG4 level was significantly elevated (1490. mg/dl; normal range: 4.8-105. mg/dl). However, laboratory findings of anemia, hypoalbuminemia, polyclonal gammaglobulinemia, high C-reactive protein level, and elevated serum interleukin-6 level were consistent with hyper-IL-6 syndrome. Hence, the diagnosis of cutaneous multicentric Castleman's disease was made. In conclusion, IgG4-related disease cannot be differentiated from hyper-IL-6 syndromes on histology alone. Instead, laboratory analyses are necessary to distinguish between the two diseases. © 2012 Elsevier GmbH.

We have reported on the clinical usefulness of human telomerase reverse transcriptase (hTERT) mRNA quantification in sera in patients with several cancers. Positron emission tomography-computed tomography (PET/CT) using F-fluorodeoxyglucose (FDG) has recently become an excellent modality for detecting cancer. We performed a diagnostic comparative study of FDG-PET/CT and hTERT mRNA quantification in patients with cancer. Four hundred seventy subjects, including 125 healthy individuals and 345 outpatients with cancer who had received medical treatments for cancer in their own or other hospitals, were enrolled. The subjects were diagnosed by FDG-PET/CT, and we measured their serum hTERT mRNA levels using real-time RT-PCR, correlating the quantified values with the clinical course. In this prospective study, we statistically assessed the sensitivity and specificity, and their clinical significance. hTERT mRNA and FDG-PET/CT were demonstrated to be correlated with the clinical parameters of metastasis and recurrence (P < 0.001), and of recurrence and tumor number in cancer compared with noncancer patients, respectively. A multivariate analysis showed a significant difference in the detection by FDG-PET/CT, F-FDG uptake, the detection by hTERT mRNA, and age. The use of both FDG-PET/CT and hTERT mRNA resulted in a positivity of 94.4% (221/234) for the detection of viable tumor cells. FDG-PET/CT is superior to hTERT mRNA quantification in the early detection of cancer and combinative use of FDG-PET/CT and hTERT mRNA may improve the diagnostic accuracy of cancer.

To determine whether fluorodeoxyglucose positron emission tomography (FDG-PET) before and after palliative radiation therapy (RT) can predict long-term pain control in patients with painful bone metastases.Thirty-one patients with bone metastases who received RT were prospectively included. Forty painful metastatic treatment fields were evaluated. All patients had undergone pre-RT and post-RT PET/CT scanning. We evaluated the relationships between the pre-RT, post-RT, and changes in maximum standardized uptake value (SUVmax) and the pain response, and between SUVmax and pain relapse of the bone metastases in the treatment field. In addition, we compared the SUVmax according to the length of time from the completion of RT to pain relapse of the bone metastases.Regarding the pain response at 4 weeks after the completion of RT, there were 36 lesions of 27 patients in the responder group and 4 lesions of 4 patients in the nonresponder group. Changes in the SUVmax differed significantly between the responder and nonresponder groups in both the early and delayed phases (P=.0292 and P=.0139, respectively), but no relationship was observed between the pre-RT and post-RT SUVmax relative to the pain response. The responder group was evaluated for the rate of relapse. Thirty-five lesions of 26 patients in the responder group were evaluated, because 1 patient died of acute renal failure at 2 months after RT. Twelve lesions (34%) showed pain relapse, and 23 lesions (66%) did not. There were significant differences between the relapse and nonrelapse patients in terms of the pre-RT (early/delayed phases: P<.0001/P<.0001), post-RT (P=.0199/P=.0261), and changes in SUVmax (P=.0004/P=.004).FDG-PET may help predict the outcome of pain control in the treatment field after palliative RT for painful bone metastases.

Background : Early operation for hip fracture patients is considered to have better outcome. Therefore, early operation was performed even if patients had been treated with antiplatelet and/or anticoagulating drugs (AP/AC) in our hospital for the past two years. This retrospective study was undertaken as excessive blood loss is expected in patients treated with AP/AC. Methods : Elderly patients for hip fracture surgery were retrospectively studied in our hospital for the past two years. Perioperative decrease in hemoglobin level and the incidence of transfusion were compared between patients treated with AP/AC and those not treated. Results : Sixty-four patients were treated with AP/AC and one hundred ninety-nine patients were not treated. Patients treated with AP/AC had more preoperative complications and worse ASA-PS scores. General anesthesia was used more frequently for patients with AP/AC. In the perioperative decrease in hemoglobin level and the incidence of transfusion, there were no significant differences between the groups. Conclusions : Perioperative bleeding for hip fracture surgery was compared between patients treated with and without AP/AC. No significant difference was observed, and, discontinuation of AP/AC might not be necessary for hip fracture surgery.

A 55-year-old male had complained of melena.Colonoscopy revealed a type 2 tumor at the rectum.CT demonstrated hepatic lymph nodes and multiple liver metastases(stage IV).Low anterior resection was performed(tub2, RsRa, circ, type 2, pSS, pN1, sH3, cHN1, sP0, cM0: fstage IV).The patient was treated with mFOLFOX6 and sLV5FU2 after operation.CT revealed a partial response after 14 courses of systemic chemotherapy.sLV5 FU2 therapy was converted to capecitabine because he experienced bone marrow suppression.CT showed that the liver metastases had enlarged but the hepatic lymph nodes disappeared.Right portal vein embolization was performed.After 4 weeks, right hepatectomy and hepatic lymph node dissection were performed.Preoperative chemotherapy with mFOLFOX6 seems beneficial as a neoadjuvant chemotherapy for hepatic lymph node-positive advanced colorectal cancer.

An 80-year-old woman with a history of chronic hepatitis B was referred to our hospital because of upper gastrointestinal bleeding of unknown origin. Dynamic computed tomography revealed liver cirrhosis and hepatofugal collateral vessels around the duodenum. Emergency esophagogastroduodenoscopy showed duodenal varices with an erosive spot, highly suggestive of a variceal rupture site. We immediately performed endoscopic clipping of the ruptured site to achieve temporary hemostasis. Ten days later, elective balloon-occluded retrograde transvenous obliteration (B-RTO) was performed to prevent recurrence. We describe a successfully treated case of duodenal variceal rupture managed by combination therapy with endoscopic clipping and B-RTO.
