A 6-month-old male Ragdoll cat presented with exercise intolerance. On physical examination, there was a grade 2/6 systolic murmur at the right apex. Diagnostic tests, including SpO2 measurement, blood tests, radiography, echocardiography, contrast echocardiography, and electrocardiography, were performed. Severe right atrial dilation, tricuspid valve leaflets and orifice displacement, right ventricular atrialization, septal leaflet adherence, anterior leaflet tethering, and right atrioventricular junction dilation were noted on echocardiography, alongside a right-to-left atrial septal defect. Cor triatriatum dexter and left ventricular aneurysm were observed. We diagnosed this case as having Ebstein anomaly with rare congenital heart deformities; which is rare in cats.

Over the past decades, ultrasound imaging technology has made tremendous progress in obtaining important diagnostic information from patients in a rapid, noninvasive manner. Although the technology has benefited from sophisticated signal processing technology and imaging system integration, much of this progress has been derived from the development of ultrasonic transducers that are in direct contact with patients. An overview of medical ultrasonic imaging transducers is presented in this review that describes their structure, types, and application fields. The structural components of a typical transducer are presented in detail including an active layer, acoustic matching layers, a backing block, an acoustic lens, and kerfs. The types of transducers are classified according to the dimensions of ultrasound images: one-dimensional array, mechanical wobbling, and two-dimensional array transducers. Advantages of each transducer over the other and the technical issues for further performance enhancement are described. Application of the transducers to various clinical imaging fields is also reviewed.

Objectives: Recently, the clinical importance of attention deficit hyperactivity disorder (ADHD) and problem/pathological gambling has been increasing. Studies on the relationship between ADHD and problem/pathological gambling are ongoing worldwide but few are conducted. This study examined the relationship between adult ADHD symptoms and problem/pathological gambling. Methods: Data from 500 adults aged 20 to 59 who took part in a community survey were analyzed. All participants completed self-report questionnaires in which demographic variables and ADHD symptoms were assessed using the Adult ADHD Self-Report Scale. Problem/pathological gambling was assessed using a Korean version of the Diagnostic Interview Schedule. Results: The prevalence of adult ADHD symptoms was 15.2%. The association between ADHD symptoms and problem/pathological gambling was significant (p<0.001). Additionally, subjects with ADHD symptoms showed a more positive attitude toward gambling than subjects without symptoms. Multivariate analysis revealed a significant relationship between ADHD symptoms and problem/pathological gambling (odds ratio, 2.394; 95% confidence interval, 1.104–5.191;p=0.027). Conclusion Problem/pathological gambling is associated with ADHD symptoms. Therefore, clinicians should provide education and intervention on gambling behavior to subjects with ADHD symptoms.

The purpose of this study was to compare the color of maxillary primary central incisors, lateral incisors, canines with the color of various composite resins using a spectrophotometer VITA Easyshade®V.One researcher measured the color of sound maxillary primary anterior teeth of 100 children aged 1 to 6 and specimens which were made by composite resins with a total of 10 types and 31 shades, and CIE L*, a*, b* values were obtained.There was no clinically recognizable color difference between the maxillary primary central and lateral incisors. However, the maxillary primary canines showed difference in color above the clinical acceptability threshold with the primary central and lateral incisors. These findings showed no significant color differences between men and women, and no significant color changes with age. A1 shade is the most common in all maxillary primary anterior teeth.Composite resins, which are thought to be similar to the color of maxillary primary anterior teeth were selected from 9 types of maxillary primary central incisors, 6 types of primary lateral incisors, 6 types of primary canines.

The objective of this study is to analyze the shear bond strength of orthodontic buttons according to light tip distance and optic fiber diameter when an extended optic fiber was applied to the tip of a curing light unit.
In this study, 315 extracted premolar teeth were divided into 3 groups. Orthodontic buttons were attached using no optic fibers (Group I), 3.0 mm diameter optic fibers (Group II), or 5.0 mm diameter optic fibers (Group III). Each group was divided into subgroups A - C (5.0, 10.0, and 15.0 mm light tip distance), respectively. Shear bond strength was then measured while varying the light tip distance.
In group I, shear bond strength significantly decreased as the light tip distance increased. When the shear bond strength was evaluated according to the optic fiber diameter, no statistical significance was observed in group of 5.0 mm light tip distance. Compared with group IB, group IIIB showed significantly greater shear bond strength. Compared with group IC, all groups using 3.0 or 5.0 mm diameter optic fibers showed significantly greater shear bond strength.
Therefore, when a curing light unit has poor accessibility, optic fibers with a large diameter should be considered.

Many packages for a meta-analysis of genome-wide association studies (GWAS) have beendeveloped to discover genetic variants. Although variations across studies must be considered, there are not many currently-accessible packages that estimate between-study heterogeneity. Thus, we propose a python based application called Beta-Meta which can easilyprocess a meta-analysis by automatically selecting between a fixed effects and a randomeffects model based on heterogeneity. Beta-Meta implements flexible input data manipulation to allow multiple meta-analyses of different genotype-phenotype associations in asingle process. It provides a step-by-step meta-analysis of GWAS for each association inthe following order: heterogeneity test, two different calculations of an effect size and ap-value based on heterogeneity, and the Benjamini-Hochberg p-value adjustment. Thesemethods enable users to validate the results of individual studies with greater statisticalpower and better estimation precision. We elaborate on these and illustrate them with examples from several studies of infertility-related disorders.

Kummell's disease is a spinal disorder characterized by delayed post-traumatic collapse of a vertebral body with avascular necrosis. Although definitive treatment for Kummell's disease has not been established, it has been reported that percutaneous vertebroplasty or kyphoplasty has shown good results. However, these procedures are not recommended for severely collapsed vertebral bodies because of the risk of cement leakage or technical difficulties. Authors report a rare case of spontaneous reduction in vertebral height by the insertion of a working cannula into the vertebral body in Kummell's disease.
