RESUMO
This is a case of a 13-year-old male with frequent premature ventricular contractions with QRS configurations of the left superior axis and left bundle branch block, which originated from the posterior-superior process of the left ventricle. Premature ventricular contractions were successfully eliminated by delivering radiofrequency energy to the inferior wall of the right atrium without causing either junctional rhythm or atrioventricular block. Ventricular arrhythmias originating from this site have been sporadically reported in adults; however, this is the first report in a child.
RESUMO
INTRODUCTION: Total anomalous pulmonary venous connection (TAPVC) has a low prenatal diagnostic rate. Therefore, we investigated whether Doppler waveforms with a low pulsatility in the pulmonary veins can indicate fetal TAPVC. METHODS: This retrospective study included 16 fetuses with TAPVC, including 10 with complex congenital heart disease and 104 healthy fetuses that underwent fetal echocardiography. Pulmonary venous S and D wave flow velocities and the valley (representing the lowest velocity between the S and D waves) were measured. Valley indices I and II were then calculated as (velocity of valley/greater of the S and D wave velocities) and (velocity of valley/lesser of the S and D wave velocities), respectively. RESULTS: Supra/infracardiac TAPVC cases exhibited significantly greater valley indices than that of the healthy group. After adjusting for gestational age at fetal echocardiography, valley indices I (odds ratio [OR] 7.26, p < 0.01) and II (OR: 9.23, p < 0.01) were significant predictors of supra/infracardiac TAPVC. Furthermore, valley indices I and II exhibited a high area under the curve for detecting supra/infracardiac TAPVC, regardless of the presence of pulmonary venous obstruction. CONCLUSION: The valley index may be a useful tool for the detection of fetal TAPVC.
RESUMO
PURPOSE: To create an equation for identifying post-myopic laser vision correction (M-LVC) eyes by using corneal shape parameters in swept-source optical coherence tomography (SS-OCT) biometer and verify its accuracy. SETTING: Nagoya eye clinic, Nagoya, Japan. DESIGN: Retrospective evaluation of a screening approach. METHODS: The control participants were selected retrospectively from patients who visited our clinic for cataract surgery or refractive surgery. M-LVC patients were selected retrospectively from patients who visited our clinic for cataract surgery or M-LVC postoperative checkups. The control and post-M-LVC patients with keratometric values between 39 diopters (D) and 43 D were included in the final analysis. Patients were randomly assigned to equation-creation and validation groups in a 2:1 ratio. To discriminate post-M-LVC patients from control participants, multiple logistic regression analysis was performed with the corneal shape parameters from the optical biometer as independent variables. RESULTS: The M-LVC and control groups consisted of 90 eyes from 90 patients and 97 eyes from 97 patients, respectively. The average keratometry (Ave-K) values did not differ significantly between the control and M-LVC groups (p=0.187). The multiple logistic analysis identified the asymmetry component (regression coefficient, 5.357; odds ratio, 212.158) and corneal eccentricity index (regression coefficient, -5.088; odds ratio, 0.006) as explanatory variables. The area under the receiver operating characteristic curve in the predictive equation-creation group was 0.946. The sensitivity and specificity in the validation group were 93.3% and 87.5%, respectively. CONCLUSIONS: The M-LVC discriminant prediction equation with the topography-equipped SS-OCT biometer was effective in detecting post-M-LVC eyes with high accuracy.
RESUMO
AIM: The present study aimed to determine whether decreased masticatory performance and tongue-lip motor function are associated with an increased incidence of adverse health events in patients with metabolic disease. METHODS: One thousand patients with metabolic diseases including diabetes, dyslipidemia, hypertension, and hyperuricemia were recruited. Masticatory performance was assessed using a gummy jelly test, wherein glucose elution from chewed gummy jelly was measured. The tongue-lip motor function was measured using repeatedly pronounced syllables per second. Their association with the incidence of adverse health events (a composite of all-cause death, cardiovascular disease, bone fracture, malignant neoplasm, pneumonia, and dementia) was investigated using the generalized propensity score (GPS) method. RESULTS: During a median follow-up period of 36.6 (interquartile range, 35.0-37.7) months, adverse health events were observed in 191 patients. The GPS adjusted dose-response function demonstrated that masticatory performance was inversely associated with the incidence of adverse health events. The 3-year incidence rate was 22.8% (95% confidence interval, 19.0-26.4%) for the lower quartile versus 13.6% (10.5-16.7%) for the upper quartile (Pï¼0.001). Similarly, the tongue-lip motor function was inversely associated with the incidence of adverse health events, with a 3-year incidence rate of 23.6% (20.0-27.0%) for the lower quartile versus 13.2% (10.4-15.9%) for the upper quartile (Pï¼0.001). CONCLUSIONS: Decreased masticatory performance and tongue-lip motor function were associated with an increased incidence of adverse health events in patients with metabolic disease.
RESUMO
PURPOSE: Although the rate of diabetic retinopathy (DR)-related blindness has decreased in developed countries in recent years, the reasons for this decrease have remained unclear. The prevalence/severity trends of DR at the first visit in patients with untreated type 2 diabetes mellitus (T2DM) patients seen between the1986s and 2018s were assessed. METHODS: A total of 1979 Japanese T2DM patients diagnosed between 1986 and 2018 were divided into four groups by the decade of their first visit: the 1986 years (1986-1987), the 1996 years (1996-1997), the 2006 years (2006-2008), the 2016 years (2016-2018). The DR prevalence/severity trends were assessed. RESULTS: A significant decrease in the rate of prevalence of DR from the 1986s to 2016s was observed among previously untreated T2DM patients visiting our hospital for the first time (1986s: 25.5%; 1996s: 26.2%; 2006s: 22.2%; and 2016s: 15.6%). The prevalence was significantly higher in females (30.2%) than in males (21.3%). Although the severity trend of DR did not differ significantly among the four measurement years, the rate of simple DR was the highest in the 2016s. CONCLUSION: We found, for the first time, a significant decrease in the rate of prevalence of DR from the 1986s to 2016s in patients with untreated T2DM visiting our hospital for the first time. A decrease in the rate of DR prevalence could explain, at least in part, the observed reduction in the rate of blindness in patients with T2DM.
