Background: Coronary sinus (CS) has been shown to be larger in patients with atrioventricular nodal reentrant tachycardia (AVNRT (AUC 0.89, or tachycardia rate (AUC 0.60,. Conclusions: Echocardiographic measurement of the diameter of CS ostium can help in identifying the mechanism of the tachycardia before the invasive electrophysiology study.

ABI and CIMT are simple noninvasive tools providing insight into coronary atherosclerosis. They can be done at bedside and easily repeated than coronary angiography. ABI < 0.9 is a better surrogate marker of significant coronary atherosclerosis than CIMT > 0.63 mm in South Indians with CAD.

Congenital epulis is a rare benign lesion of new-born and occurs mostly as a single tumor. A new-born infant with congenital epulis is a striking sight for both parents and health care professionals involved in neonatal care. The tumor has a female predilection with the female to male ratio being 10:1. These tumors in the infant's mouth are remarkably large, occupying much of the oral cavity and posing a risk of airway obstruction and it can interfere with the feeding. Although the clinical presentation of the congenital tumor is rather distressing, owing to its size and aggressive appearance, it is very much necessary that the attending pediatricians, pediatric surgeon be cognizant of the nature of this rare yet benign congenital tumor. The purpose of this article is to present a case report documenting the clinical presentation and management of Congenital Epulis on the anterior maxillary alveolus in a three-day old female patient.

The electrocardiac abnormalities following acute stroke are frequent and seen in both ischemic and hemorrhagic stroke. The changes seen in electrocardiogram (ECG) consist of repolarization abnormalities such as ST elevation, ST depression, negative T waves, and QT prolongation. Among tachyarrhythmias, atrial fibrillation is the most common and occurrence of focal atrial tachycardia is very rare though any cardiac arrhythmias can follow acute stroke. We report a case of focal atrial tachycardia following acute ischemic stroke in 50-year-old female without structural heart disease, and their mechanisms and clinical implications.
<p>Compositional NOx changes caused by energetic electron precipitation (EEP) at a specific altitude are called the EEP direct effect. Changes co-dependent on vertical transport are referred to as the EEP indirect effect. The relative importance of EEP&#8217;s direct and indirect effect on NO and its subsequent impact on ozone and dynamic changes remain unresolved. The challenges are partly due to inadequate particle measurement and the relative scarcity of NO observations over the polar MLT region. Moreover, lower production rates in the mesosphere make it challenging to determine EEP&#8217;s direct impact on NO since small in-situ enhancements cannot be easily distinguished from the descending NO-rich air masses in the winter hemisphere. In this study, the uncertainty of the EEP observations is bypassed by exclusively identifying events applying NO-observations from the SOFIE instrument on board the AIM satellite. SOFIE daily averaged data from 2007 to 2014 is used to create a climatology based on the mean of the lower half of the data (lower 50 percentile mean). A direct EEP-produced NO-event at 90 km (&#8220;90km-event&#8221;) is identified when the NO density surpasses the climatology by 100%. If the NO density exceeds 25% above the climatology at 80, 70, 60, and 50 km, the event qualifies as a &#8220;50km-event&#8221;. By contrasting the 90km and 50km events, the characteristics of the solar wind and geomagnetic indices, as well as observed electron fluxes from POES, are studied. The goal is to unravel when EEP can produce NO directly in the upper stratosphere. The result will contribute to developing a parameterization of EEP from the radiation belt that includes both the direct and indirect impact of EEP to decipher the total EEP effect on the ozone and atmospheric dynamics.</p>
