those at N/C terminus) (HR = 1.42; 95%CI = 1.08-1.88; p = 0.01), C-loop (vs. N/C terminus) (HR = 1.52; 95%CI = 1.06-2.16; p = 0.02), and P variants [(vs. LP) (HR = 1.72; 95%CI = 1.32-2.26; p less then 0.0001), (vs. VUS) (HR = 1.81; 95%CI = 1.15-2.99; p = 0.009)] were significantly associated with syncopal events. Acetylcholine Chloride manufacturer The ACMG/AMP-based KCNQ1 evaluation was useful for risk stratification not only in family members but also in probands. A clinical score (0~4) based on proband, QTc (≥500ms), variant location (MS or C-loop) and P variant by ACMG/AMP guidelines allowed identification of patients more likely to have arrhythmic events. Conclusions - Comprehensive evaluation of clinical findings and pathogenicity of KCNQ1 variants based on the ACMG/AMP-based evaluation may stratify arrhythmic risk of congenital long-QT syndrome type 1.Background Hepatic attenuation at unenhanced CT is linearly correlated with MR proton density fat fraction (PDFF). Liver fat quantification at contrast-enhanced CT is more challenging. Objective To evaluate liver steatosis categorization on contrast-enhanced CT using a fully-automated deep learning volumetric hepatosplenic segmentation algorithm and unenhanced CT as the reference standard. Materials and Methods A fully-automated volumetric hepatosplenic segmentation algorithm using 3D convolutional neural networks was applied to unenhanced and contrast-enhanced series from a sample of 1204 healthy adults (mean age, 45.2 years; 726 women, 478 men) undergoing CT evaluation for renal donation. The mean volumetric attenuation was computed from all designated liver and spleen voxels. PDFF was estimated from unenhanced CT attenuation and served as the reference standard. Contrast-enhanced attenuations were evaluated for detecting PDFF thresholds of 5% (mild steatosis), 10%, and 15% (moderate); PDFF less then 5% wasy 91.4% and specificity 95.0% for moderate steatosis. Liver-spleen difference less then 10 HU achieved sensitivity 29.5% and specificity 95.5% for any steatosis (PDFF≥5%). Conclusion Contrast-enhanced volumetric hepatosplenic attenuation derived using a fully-automated deep-learning CT tool may allow objective categorical assessment of hepatic steatosis. Accuracy was better for moderate than mild steatosis. Further confirmation using different scanning protocols and vendors is warranted. Clinical Impact If these results are confirmed in independent patient samples, this automated approach could prove useful for both individualized and population-based steatosis assessment.Background Tearing of the superior peroneal retinaculum (SPR) is a known cause of peroneal tendon subluxation/dislocation (PTS). However, with the exception of cortical avulsions at its fibular attachment, SPR injury and subsequent PTS are typically radiographically occult. Objective Evaluate the previously undescribed association between radiographic fibular tip periostitis and MRI evidence of PTS, in patients with hindfoot valgus. Methods 35 patients with radiographic fibular tip periostitis and 35 age- and sex-matched controls without periostitis, were selected out of 220 consecutive patients with hindfoot valgus and both ankle radiographs and MRIs. Studies were retrospectively assessed by two musculoskeletal radiologists in consensus, and two additional blinded, independent radiologists for presence of PTS, sub-fibular impingement, and hindfoot valgus angle measurement. Inter-observer agreement and accuracy, sensitivity, and specificity for detecting fibular periostitis, PTS, and sub-fibular impingement wf PTS, and may also suggest advanced hindfoot valgus and sub-fibular impingement. These radiographic associations should be recognized by the radiologist and MRI may be recommended as clinically indicated. Clinical Impact Chronic, undiagnosed PTS can be a persistent cause of lateral ankle pain, leading to further degeneration and the possibility of complete peroneal tendon tears. Distal fibular periostitis in patients with hindfoot valgus can be a reliable radiographic indicator of this entity and may suggest the presence of sub-fibular impingement.Background Transthoracic echocardiography (TTE) is the standard of care for initial evaluation of patients with suspected cardioembolic stroke. While TTE is useful for assessing certain sources of cardiac emboli, its diagnostic capability is limited in the detection of other sources, including left atrial thrombus and aortic plaques. Objectives To investigate sensitivity, specificity and predictive value of cardiac CT angigography (cCTA), cardiac MRI (CMR), and TTE for recurrence in patients with suspected cardioembolic stroke. Methods We retrospectively included 151 patients with suspected cardioembolic stroke who underwent TTE and either CMR (n=75) or cCTA (n=76) between January 2013 and May 2017. We evaluated for presence of left atrial thrombus, left ventricular thrombus, vulnerable aortic plaque, cardiac tumors, and valvular vegetation as causes of cardioembolic stroke. The end-point was stroke recurrence. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for eferred given potentially better detection of atrial and ventricular thrombus. Clinical impact cCTA and CMR have similar clinical performance as TTE for predicting cardioembolic stroke recurrence. This observation may be especially important when TTE provides equivocal findings.Clinical evaluation of patients with trauma is challenging, especially in the presence of neurological injuries. Visual loss after trauma is a harmful and usually overlooked consequence that may be avoided with a prompt and accurate intervention. Head CT is commonly performed in patients with trauma. However, radiologists may be unfamiliar with the CT findings associated with injuries that may affect eyesight. Understanding the visual pathway anatomy and its critical landmarks is paramount for recognizing these findings. This article describes the use of head CT to evaluate the visual pathway to help avoid visual loss in patients with trauma. Injuries are presented in terms of those affecting the globe (rupture, haemorrhage, and lens trauma), optic nerve (direct and indirect traumatic optic neuropathy), orbit (orbital compression syndrome), and vasculature (carotid-cavernous sinus traumatic fistula and posterior cerebral artery injury or ischemia). Techniques for measuring the globe on CT to assess for injury are illustrated.Acetylcholine Chloride manufacturer
