Adenosine-sensitive perinodal atrial tachycardia. What is the mechanism?

Termination of focal atrial tachycardia with adenosine is considered a defining feature for triggered activity. Recent evidence, however, suggests that the perinodal adenosine-sensitive AT has reentry as the mechanism of tachycardia. In this report, we were able to confirm the mechanism of AT as reentry by observing the response to programmed electrical stimulation and demonstrating the fallacy of traditional teaching that the adenosine responsiveness of AT is a criterion for labeling the mechanism as triggered activity.

The applicability of the Demirjian, Willems and Chaillet standards to age estimation of 5-15 year old Indian children.

Background: Demirjian's method of age estimation has been reported to overestimate age and Willems' method to give consistently more accurate results. Not enough, however, is known about the applicability of Chaillet's standards.

Aim: The present study aimed to compare the accuracy of Demirjian's, Willems' and Chaillet's standards in age estimation of 5 to 15 year-old Indian children.

Posterior Reversible Encephalopathy Syndrome in a Patient of Sepsis-induced Cardiomyopathy, Successfully Managed with Intra-aortic Balloon Pump.

In patients with septic shock refractory to pharmacological agents, mechanical devices have been used successfully, although the reports are scarce. We report a case of septic shock where intra-aortic balloon pump (IABP) initiation leads to drastic improvement and survival from severe septic cardiomyopathy when conventional therapy was not effective. A 19-year-old male patient underwent surgery for adenocarcinoma descending colon.

The applicability of the original and revised Demirjian standards to age estimations of 5-15 year old Indian children.

Background: The Demirjian method has been the most widely tested method for the estimation of the dental age of children and adolescents. However, only three studies have compared Demirjian's original and revised seven-tooth methods, four-tooth method and alternate four-tooth method, none of them conducted on an Indian population.

Aim: The present study aimed to compare the applicability of the original and revised seven-tooth and four-tooth and alternate four-tooth standards for age estimation of 1200 Indian children aged 5-15 years old.
