Use of deep convolutional neural network-based features for detection of cardiac sarcoidosis from polar map

Conclusions: The classification performance of DCNN-based features outperformed the CoV-based classification performance. Experimental results suggested that DCNN-based high-dimensional features have a potential of semi-automated diagnosis of CS.

The objective of this study was to evaluate screw choices for three-dimensional (3D) digital pre-operative planning of osteosynthesis of distal radius fractures and to compare with the screw choices for the conventional method. METHODS: Distal radius fracture patients who underwent osteosynthesis using volar locking plates were evaluated. Thirty wrists in the plan group utilized 3D preoperative planning, and nineteen wrists in the control group utilized conventional preoperative assessment. In the plan group, the 3D preoperative planning was performed prior to surgery. The reduction was simulated with 3D image, and th...

The objective of this study was to clarify the difference in thumb deformity between our case with ring chromosome 4 and thumb polydactyly, in which ulnar side was small and had no active motion, and other cases of ring chromosome 4, by analyzing previous reports. Our case had bilateral atypical thumb polydactyly, which was classified as type 4 on the right side and type 5 on the left side, according to the Japanese Society for Surgery of the Hand: Modified International Federation of Societies for Surgery of the Hand classification. Of the 39 cases in previous reports, 20 (51.3%) had thumb deformities. Among them, 19 case...

This study aims to evaluate the accuracy of patient-specific computed tomography (CT)-based rapid prototype drill guide templates for the CBT technique. CT scanning was performed in 7 cadaveric thoracolumbar spines, and a 3-dimensional reconstruction model was generated. By using computer software, we constructed drill templates that fit onto the posterior surface of thoracolumbar vertebrae with drill guides to match the CBT. In total, 80 guide templates from T11 to L5 were created from the computer models by using rapid prototyping. The drill templates were used to guide the drilling of CBT screws without any fluoroscopic...

Purpose: To compare foveal vascular anatomy between patients with and without disorganization of retinal inner layers (DRILs) after resolved diabetic macular edema using optical coherence tomography angiography (OCTA). Methods: Twenty-four eyes of 21 age- and sex-matched patients with resolved diabetic macular edema were included in this retrospective, cross-sectional study. All eyes were imaged with enhanced high-definition line or cross-line structural B scans and 3 × 3-mm OCTA scans. Optical coherence tomography B scans were analyzed for the presence of DRIL, and based on this, eyes were classified as either ...

Purpose: To evaluate structural changes in the choroid of patients with Stargardt disease using swept source optical coherence tomography scans. Methods: A retrospective comparison cohort study was conducted on 39 patients with Stargardt disease, and on 25 age and gender matched-healthy controls. Subfoveal choroidal thickness (SFCT) was computed from the swept source optical coherence tomography machine, and the scans were binarized into luminal area and stromal areas, which were then used to derive choroidal vascularity index (CVI). Choroidal vascularity index and SFCT were analyzed independently using linear mixed e...

Abstract Sarcoidosis is a systemic disease characterized by noncaseating granulomas and is often a diagnosis of exclusion. The actual prevalence of cardiac sarcoidosis (CS) is unknown, as studies have demonstrated mixed data. CS may be asymptomatic and is likely more frequently encountered than previously thought. Sudden death may often be the presenting feature of CS. Most deaths attributed to CS are caused by arrhythmias or conduction system disease, and congestive heart failure may occur. Current expert consensus on diagnosis of CS continues to rely on endomyocardial biopsy, in the absence of which, histologic ...

Conclusions CS patients showed higher FDG uptake and lower RI than non-CS patients. The regional analysis demonstrated the significant correlation between FDG uptake and SNS dysfunction. The FDG uptake region was larger than SNS dysfunction region in the patients without a history of steroid therapy. SNS dysfunction may persist even the FDG uptake was decreased after steroid therapy. $$graphic_688B7EA9-8D3C-4175-A919-8B09C8328477$$ $$graphic_45523217-7CD7-486C-990B-B1B4CFABCC3A$$

Conclusions Holter monitoring provides a useful, convenient and inexpensive mean of non-invasive screening for cardiac involvement in sarcoidosis especially in patients without cardiac symptoms. Extended holter should be a part of the routine work-up of any patient with sarcoidosis. The exact effect of steroid therapy on the arrhythmia burden remains a matter of debate. Cardiac MRI should be done to all patients with sarcoidosis having either abnormal symptoms or abnormal basic screening tools especially abnormal holter.
