The Seventh Prevention of Syncope Trial (POST VII)-A randomized clinical trial of atomoxetine for the prevention of vasovagal syncope: Rationale and study design.

Background: Vasovagal syncope (VVS) is common, recurs, and is associated with markedly reduced quality of life, anxiety, and frequent injuries. The few pharmacological therapies for VVS proven to have a moderate benefit in reducing recurrences are limited to patients without coexisting conditions such as hypertension or heart failure. Although there is some data to suggest Atomoxetine, a norepinephrine reuptake transport inhibitor (NET), may be a promising treatment option, an adequately powered randomized placebo-controlled trial is needed.

Atomoxetine for suppression of vasovagal syncope.

Objective: Vasovagal syncope (VVS) is a common clinical condition with few effective medical therapies. The study aimed to evaluate the effectiveness of atomoxetine in suppressing syncope in patients with recurrent VVS.

Methods: This was a retrospective, open-label, observational case series of 12 patients taking atomoxetine for suppression of recurrent vasovagal syncope.

Variations in IgG antibody subclass responses to oral bacteria: Effects of periodontal disease and modifying factors.

Background And Objective: Local and systemic IgG antibodies or oral bacteria have been described with periodontitis. We extended these observations by assessing the impact of a range of intrinsic factors on serum IgG subclass antibodies to both commensal and pathogenic oral bacteria that would contribute to variations in immune protection or disease susceptibility in periodontitis have not been described.

Methods: Subjects (n = 278) were classified as healthy, gingivitis, or periodontitis and categorized as mild, moderate, and severe periodontitis.

Successful use of calcium channel blocker for management of arterio-venous malformations following Fontan procedure.

In diffuse forms of arteriovenous malformation following Fontan procedure, "classical" medical therapy, inhaled nitric oxide and sildenafil, may play a role, until re-direction of hepatic flow to pulmonary circulation cures it. However, in refractory cases, as reported in our 2-year-old patient, unusual medications such as calcium channel blockers can be tried and continued if patients respond adequately.

Modified Senning Procedure for Correction of Atrioventricular Discordance With Total Anomalous Pulmonary Venous Return, Atrial Situs Inversus, Dextrocardia, and Bilateral Superior Venae Cavae.

The Senning and Mustard baffles remain important techniques for the treatment of congenitally corrected transposition (cc-TGA), isolated ventricular inversion, and D-transposition of the great arteries with delayed presentation. We describe the treatment of an 8-month old infant with atrioventricular discordance, ventriculoarterial concordance, and dextrocardia with atrial situs inversus. A modified Senning procedure was performed through the "left-sided" atrium.
