Crow-Fukase syndrome associated with high-output heart failure

金沢大学医薬保健研究域医学系A 64-year-old woman was admitted with systemic edema and exertional dyspnea. High-output heart failure was diagnosed by right heart catheterization and she was treated with diuretics. After 3 weeks, her symptoms disappeared but a high cardiac output state persisted. A diagnosis of Crow-Fukase syndrome was made based on the presence of polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes. Her serum vascular endothelial growth factor (VEGF) level was markedly elevated after recovery from heart failure. We suspect that an elevated VEGF level and a high cardiac output state may play a role in the pathogenesis of heart failure in Crow-Fukase syndrome

Fatal or not? Finding errors that lead to dialogue breakdowns in chat-oriented dialogue systems

This paper aims to find errors that lead to dialogue breakdowns in chat-oriented dia-logue systems. We collected chat dialogue data, annotated them with dialogue break-down labels, and collected comments de-scribing the error that led to the break-down. By mining the comments, we first identified error types. Then, we calculated the correlation between an error type and the degree of dialogue breakdown it in-curred, quantifying its impact on dialogue breakdown. This is the first study to quan-titatively analyze error types and their ef-fect in chat-oriented dialogue systems.

What Are Possible Contributors to Associated Dental Injury in Mandibular Fractures?

PURPOSE Among previous reports on dental injuries associated with mandibular fractures, there are few investigating the conditions under which dental injuries commonly occur. The aim of this study was to determine specific characteristics of mandibular fractures accompanied by dental injuries. METHODS This retrospective cohort study included dentate patients with mandibular fractures treated at a tertiary trauma center between 2011 and 2019. The data were analyzed according to 2 outcome variables: patients with additional dental injuries and patients without. The predictor variables were patient age, sex, accident mechanism, number and location of mandibular fractures, and presence of submental lacerations. Odds ratios for the risk factors for dental injury were calculated in conjunction with descriptive statistics. Binary logistic regression analysis was also performed to identify the factors associated with dental injuries as dependent variables. RESULTS Of 252 patients who had only mandibular fractures, 95 (37.7%) had associated dental injuries. In the group with dental injuries, 55.8% of mandibular fractures were caused by a fall (P = .003). Condyle fractures (77.9%) with dislocation (67.6%) and bilateral involvement (41.9%) were more common than in the group without dental injuries (P < .001). In patients with dental injuries, the incidence of 3 or more fractures (29.5%) was significantly higher than in the group without dental injuries. Dental injuries were more likely to occur in patients with concomitant submental lacerations (confidence interval (CI) 1.135-4.983, P = .02), and the risk of dental injury was significantly lower in the presence of angle fractures (CI 0.113-0.999, P = .045). CONCLUSIONS A frontal impact involving the anterior part of the mandible is often associated with condyle and multiple mandibular fractures. This seems to be the typical mechanism for concomitant dental injuries. Submental laceration can be considered a prime sign of associated dental injuries

The usefulness of wire-guided endoscopic snare papillectomy for tumors of the major duodenal papilla.

ObjectivesAlthough endoscopic papillectomy is useful for treating papillary tumors, it is associated with a high rate of complications including pancreatitis; therefore, safer treatment options are needed. We examined the utility of wire-guided endoscopic papillectomy by comparing the pancreatic duct stenting and pancreatitis rates before and after wire-guided endoscopic papillectomy was introduced at our institution.MethodsWe retrospectively examined the data from 16 consecutive patients who underwent conventional endoscopic papillectomy between November 1995 and July 2005 and the data from 33 patients in whom wire-guided endoscopic papillectomy was first attempted at our institution between August 2005 and April 2017. We compared the pancreatic duct stenting and pancreatitis rates between the two groups.ResultsOf the 33 patients in whom wire-guided endoscopic papillectomy was first attempted, the procedure was completed in 21. Pancreatic duct stenting was possible in 30 of the 33 patients in whom wire-guided endoscopic papillectomy was attempted (91%), and this rate was significantly higher than that before the introduction of wire-guided endoscopic papillectomy (68.8%). The incidence of pancreatitis before the introduction of wire-guided endoscopic papillectomy was 12.5%, but after August 2005, the incidence was reduced by half to 6.1%, which includes those patients in whom wire-guided endoscopic papillectomy could not be completed.ConclusionsAlthough wire-guided endoscopic papillectomy cannot be completed in some patients, we believe that this method shows some potential for reducing the total incidence of post-endoscopic papillectomy pancreatitis owing to more successful pancreatic duct stenting
