RESUMO
PURPOSE: To develop and validate a CT diagnostic algorithm for bicuspid aortic valve (BAV) classification. MATERIALS AND METHODS: This retrospective study included 212 consecutive patients with severe aortic stenosis who underwent CT followed by aortic valve replacement (mean age, 71 years [range, 27-93 years]; 125 women; 37% with a BAV) from 2012 to 2017. BAV diagnosis and BAV category were determined by using the CT diagnostic algorithm developed and were compared with those attained through surgical diagnosis. Reproducibility and agreement were assessed using the Cohen kappa (κ) coefficient. The value of adding CT to age, aortic diameter index, and transthoracic echocardiography (TTE) was evaluated by using the area under the receiver operating characteristic curve (AUC), net reclassification improvement (NRI), and decision-curve analysis. RESULTS: Intra- and interobserver reproducibility were good or excellent for all CT diagnoses (κ ≥ 0.6 for all). Agreement between CT and surgical diagnoses was excellent (κ = 0.90) for BAV detection and good (κ = 0.69) for BAV categorization. Sixteen percent (five of 31) of patients with functional BAV diagnosed by using CT received a diagnosis of congenital BAV at surgery. The addition of CT to age, aortic diameter, and TTE showed a higher AUC (with CT, 0.97 [95% CI: 0.91, 0.99] vs without CT, 0.91 [95% CI: 0.85, 0.95]; P = .003) and NRI (1.79 [95% CI: 1.65, 1.92], P < .001) and a higher net benefit among all BAV probabilities. CONCLUSION: CT diagnosis was consistent with surgical diagnosis and had an additive value over traditional diagnostic methods; however, there was a risk of overlooking congenital BAV in patients with functional BAV diagnosed by using CT.Supplemental material is available for this article.© RSNA, 2021.

RESUMO
OBJECTIVE: The aim of this prospective multicenter randomized controlled trial was to compare the efficacy of silver nitrate cauterization against that of topical steroid ointment in the treatment of neonatal umbilical granuloma. METHODS: An open-label, non-inferiority randomized controlled trial was conducted from January 2013 to January 2016. The primary endpoint for the silver nitrate cauterization and topical steroid ointment groups was the healing rate after 2 weeks of treatment, applying a non-inferiority margin of 10%. The healing rate was evaluated until completion of 3 weeks of treatment. RESULTS: Participants comprised 207 neonates with newly diagnosed umbilical granuloma, randomized to receive silver nitrate cauterization (n = 104) or topical steroid ointment (n = 103). Healing rates after 2 weeks of treatment were 87.5% (91/104) in the silver nitrate cauterization and 82% (82/100) in the topical steroid ointment group group. The difference between groups was -5.5% (95% confidence interval, -19.1%, 8.4%), indicating that the non-inferiority criterion was not met. After 3 weeks of treatment, the healing rate with topical steroid ointment treatment was almost identical to that of silver nitrate cauterization (94/104 [90.4%] vs. 91/100 [91.0%]; 0.6% [-13.2 to 14.3]). No major complications occurred in either group. CONCLUSIONS: This study did not establish non-inferiority of topical steroid ointment treatment relative to silver nitrate cauterization, presumably due to lower healing rates than expected leading to an underpowered trial. However, considering that silver nitrate cauterization carries a distinct risk of chemical burns and that the overall efficacy of topical steroid ointment treatment is similar to that of silver nitrate cauterization, topical steroid ointment might be considered as a good alternative in the treatment of neonatal umbilical granuloma due to its safety and simplicity. To clarify non-inferiority, a larger study is needed.

ObjectivesãPersonal income affects dental status in older people. However, the impact of income inequality on dental status at the community level (junior high school district) is unclear. The purpose of this study was to examine the association between dental status and community level income inequity after adjust for individual socio-economic status in Japanese older adults, and to verify the relative income hypothesis, also known as the Wilkinson hypothesis.MethodsãWe used data from the Japan Gerontological Evaluation Study (JAGES) conducted in Niigata city. JAGES is a postal survey of functionally independent adults aged 65 years or older. We enrolled 4,983 respondents (response rate 62.3%) and used data on 3,980 of them after excluding incomplete data. We evaluated health condition and socio-economic status using questionnaires. The Gini coefficient, as an indicator of income inequality, was calculated by junior high school district (57 districts) based on the data from the questionnaire. Additionally, the Pearson's coefficient of correlation was calculated to evaluate the association between the mean number of remaining teeth and the community level Gini coefficient. Then we evaluated the mean number of remaining teeth among the groups stratified by the Gini coefficient conditions. Next, we conducted a multilevel analysis using an ordinal logistic regression model. The number of remaining teeth was set as the dependent variable, while sex, age, household size, education, smoking status, diabetes treatment, current living conditions, and equivalent income were used as independent variables at the individual level. The Gini coefficient and average equivalent income in the junior high school district were used as independent variables at the community level.ResultsãThe Pearson's correlation coefficient for the relationship between the Gini coefficient and the mean number of remaining teeth in the junior high school district was -0.44 (P<0.01). Wider income disparity area (Gini coefficientâ§0.35) revealed a significantly small number of remaining teeth (P<0.001). The multilevel analysis showed that a higher Gini coefficient and a lower average equivalent income at the community level were significantly associated with a lower number of remaining teeth, and with educational attainment, smoking status, current living conditions, and equivalent income at the individual level, after adjusting for sex and age. On the other hand, educational attainment at the individual level, and average equivalent income at the community level were not significant factors after adjusting for all individual level variables.ConclusionãThis study showed that, in addition to individual socio-economic status, income inequality at the community level was significantly associated with number of remaining teeth in Japanese older adults. Although the precise mechanism of this association is still unclear, our result supports the relative income hypothesis.

BACKGROUND: Approximately one-third of the patients undergoing cardiovascular surgery reportedly experience paroxysmal atrial fibrillation (AF) during the postoperative period. However, the usefulness of antiarrhythmic drugs for preventing postoperative AF recurrence in the Japanese population has not been extensively studied. METHODS: From a total of 118 patients who developed postoperative paroxysmal AF between April 2009 and March 2011, 72 patients (45 men, mean age 68±8 years) requiring treatment for postoperative AF due to symptoms lasting ≥30 min were enrolled to prospectively investigate the efficacy of oral bepridil (100 mg/day, n=37) or aprindine (40 mg/day, n=35). RESULT: The AF recurrence-free survival rates at 1, 3, 7, and 14 days were 100%, 94%, 57%, and 49%, respectively, in the aprindine group, and 100%, 97%, 86%, and 76%, respectively, in the bepridil group (P=0.028, aprindine vs. bepridil). CONCLUSION: Bepridil, at a fixed dose of 100 mg/day, was considered to be more effective than a routine dose of aprindine for the prevention of postoperative AF recurrence.
RESUMO
A 59-year-old woman visited a local hospital for fever and was diagnosed as having infective endocarditis (IE) on the basis of blood cultures and transthoracic echocardiography. Based on clinical episodes of subarachnoid hemorrhage after admission, it was judged that she was not a good candidate for urgent open heart surgery, and it was decided to treat her with conservative medical therapy for the acute phase. We explored the optimum timing for surgery by employing gadolinium (Gd) contrast medium-enhanced magnetic resonance imaging (MRI) T2* weighted image (black dots) due to her high risk of perioperative cerebral hemorrhage. After the disappearance of the contrast media enhancement effect around the black dots, open heart surgery was performed successfully on the 103rd hospitalization day. The patient was discharged 22 days after the surgery with no clinical complications. This case suggests that disappearance of the contrast media enhancement effect around the black dots may be a useful marker for optimal timing of surgery to minimize the risk of perioperative cerebral hemorrhage in patients with IE. Learning Objective. The MRI T2* weighted images including those with Gd contrast medium enhancement effect may be useful for evaluating the risk of perioperative intracranial hemorrhage in IE.
RESUMO
Little is known about the risk factors for long-term poor outcome in pediatric renal transplantation. Between 1973 and 2010, 111 renal transplants (92 living donations) were performed in 104 children (56 males, mean age, 12.5 yr) at the Social Insurance Chukyo Hospital, and followed-up for a mean period of 13.6 yr. The patient survival at 1, 5, 10, 15, 20 (living- and deceased-donor transplants), and 30 yr (living-donor transplants only) was 98.1%, 92.8%, 87.8%, 84.9%, 82.6%, and 79.3%. The graft survival at 1, 5, 10, 15, 20, and 30 yr was 92.0%, 77.3%, 58.4%, 50.8%, 38.5%, and 33.3%. The most common cause of graft loss was CAI, AR, death with functioning, recurrent primary disease, ATN, and malignancy. Donor gender, ATN, malignancy/cardiovascular events, and eras affected patient survival. AR and CAI were the risk factors for graft loss. The evolved immunosuppression protocols improved the outcome by reducing AR episodes and ATN but not CAI, suggesting CAI as the major risk factor for graft loss. CAI was correlated with AR episodes, CMV infection, and post-transplant hypertension. Strategies for preventing the risk factors for malignancy/cardiovascular events and CAI, including hypertension/infection, are crucial for better outcomes.

We report a case of facial diffuse large B-cell lymphoma (DLBCL) associated with recurrent metastasis in the heart and other sites in a 76-year-old Japanese woman. Initially, she developed DLBCL in her left upper eyelid that spread into the left orbit (Ann Arbor classification stage I). The lesion went into clinical regression after 4 cycles of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy followed by radiotherapy. More than 3 years later, the lymphoma recurred in her facial skin, together with metastases in the mediastinal lymph nodes and the heart; the tumor in the heart was successfully detected by PET/CT and cardiac MRI. To treat the recurrent lesions, we performed a salvage chemotherapy regimen comprising prednisone, etoposide, procarbazine, and cyclophosphamide, which successfully induced tumor regression.
RESUMO
BACKGROUND: It has been reported that approximately one-third of patients undergoing cardiovascular surgery experience paroxysmal atrial fibrillation (AF) during the postoperative period. There is, however, little information on the selection of anti-arrhythmic drugs for terminating postoperative paroxysmal AF. METHODS AND RESULTS: Between April 2007 and March 2009, 118 patients (76 men, 42 women, mean age 68+/-10 years) who had postoperative paroxysmal AF lasting > or =30 min were randomly assigned to receive either iv cibenzoline (70 mg, n=60) or disopyramide (50 mg, n=58) for terminating postoperative paroxysmal AF. The success rate of iv cibenzoline therapy (47%) was significantly greater than that of iv disopyramide therapy (24%; P<0.05). To identify clinical factors to increase the termination efficacy of iv cibenzoline, multivariate logistic regression was used to adjust for several covariates and to generate adjusted odds ratios (OR). The significant variables for the termination of paroxysmal AF after iv cibenzoline therapy were pretreatment with oral beta-adrenergic blockers (OR =8.224, P=0.030) and smaller left atrial dimensions (OR =0.879, P=0.039). CONCLUSIONS: The efficacy of iv cibenzoline for the termination of postoperative paroxysmal AF was significantly better than that of disopyramide, especially in patients with pre-administration of oral beta-adrenergic blockers and those with smaller left atrium.

OBJECTIVE: To assess the relationship between health-related quality of life domains and bone status, including bone metabolism, in postmenopausal Japanese community women. DESIGN: The study subjects were 88 women who were participants in a screening program for osteoporosis in 2003 without a history of mental disorders, metabolic disorders, smoking, bone fractures, and/or estrogen treatment. The participation rate was 75.9%. The age range was 50 to 68 years (mean, 57), and body mass index (BMI) ranged from 15.7 to 36.6 (mean, 22.4). Health-related quality of life domains were evaluated using the Medical Outcomes Study Short-Form 36 Health Survey, and bone mineral content was measured by quantitative ultrasound of the calcaneus. Serum total osteocalcin and serum N-telopeptide were measured by enzyme-linked immunosorbent assay. Multiple linear regression models were used to study the association of age, BMI, and eight health-related quality of life domains as independent variables in age-corrected bone status and markers of bone turnover as dependent ones. RESULTS: The participants' calcaneal Z scores by quantitative ultrasound ranged from -2.14 to 2.71. The mean Z score was -0.17 (-0.27, -0.07). Multiple regression analysis revealed that BMI (P < 0.05), physical function (P < 0.01), and role-emotional (role limitations caused by emotional problems) (P < 0.01) were factors in increasing bone mineral content. Also, a positive relationship was found between vitality (P < 0.01), social function (P < 0.05), and total osteocalcin. CONCLUSIONS: Although causality is not clear, in addition to low BMI, role limitations due to poor emotional status and low physical function are related to low bone mineral content in postmenopausal Japanese community women. These results imply that when we are concerned about osteoporosis in postmenopausal women, we should pay attention not only to their physical function but also to their psychological state.

AIM: To discuss the efficacy of endoscopic mass screening for gastric cancer. METHODS: The data used in this study were the results of mass screening programs for gastric cancer in Niigata City from 2002 to 2004. The number of participants was 35,089 in 2002, 34,557 in 2003 and 36,600 in 2004. The finding ratio referred to the final diagnosis of gastric cancer after a double check of endoscopic files and histological findings. The costs of identifying one case of gastric cancer were calculated based on the total expense for each screening program and additional close examinations. RESULTS: From the analysis of individual screening program with endoscopy, individual screening program with X-ray (ISX) and mass screening program with photofluorography (MSP) in reference to the finding ratio of gastric cancer, endoscopic examination was the best for detecting early gastric cancer, the finding ratio was 0.87% in 2004, approximately 2.7 and 4.6 times higher than those of the ISX and MSP groups. In addition, this novel method was the cheapest means regarding the cost of identifying one case of gastric cancer, which was estimated to be 1,608,000 Japanese yen in 2004. CONCLUSION: Endoscopic mass screening is a promising method and can be effectively applied if a sufficient number of skilled endoscopists become available to staff the system and if city offices support it.

Systemic light-chain deposition due to plasma cell dyscrasias manifests as a form of restrictive cardiomyopathy with diastolic ventricular dysfunction. Although these manifestations are likely to be cardiac amyloidosis, whether these pathological conditions are reversible after treatment of the underlying plasma cell disorders is unknown. To our knowledge, we describe the first patient with cardiac light-chain deposition due to multiple myeloma in whom echocardiographic and biochemical factors of cardiac function were ameliorated dramatically after remission of this disorder. We emphasize that restrictive cardiomyopathy due to light-chain deposition may be reversible and have a relatively better prognosis after remission of plasma cell dyscrasias.
