Results from a small trial indicate that radiofrequency ablation can be an effective treatment for atrial fibrillation in patients with atrial septal defects.

Yet another large study has found that testosterone replacement therapy is more likely to reduce than increase the risk of major adverse cardiac events.

A white paper from the American Urological Association warns physicians about significant problems with existing testosterone evaluation practices and outlines strategies for ensuring the right patients receive the right replacement therapy.

Research shows that a follow-up strategy designed specifically for patients who visit the hospital with atrial fibrillation reduces future admissions and patient deaths more than a general follow-up plan.

In the first documented instance of its kind, a child was recently successfully treated for severe anaphylaxis triggered by eating an orange.

New research contradicts earlier findings that race is a risk factor for atrial fibrillation but finds that excess body fat may be riskier than anyone realized if that fat is stored around the heart.

According to the Pharmacovigilance Risk Assessment Committee, there is no consistent evidence showing that the use of testosterone replacement therapy increases the risk of heart problems in men with low testosterone.

Researchers from Vanderbilt University have developed a new tool for deciding when hospitals should admit patients with symptomatic atrial fibrillation and when they should send them home.

New research bolsters the case that testosterone plays a vital role in brain function and that age-related declines in testosterone are associated with age-related declines in cognitive ability.

Researchers report a nearly 25% increase in the number of emergency room vistis for atrial fibrillation.

A survey of more than 400 pediatricians and internists revealed a surprising lack of knowledge about current allergy treatment guidelines.

New research casts doubt upon the fear that testosterone replacement therapy increases the risk that men will develop prostate cancer, even if men use such therapy for years.

Sublingual immunotherapy was developed nearly 30 years ago as an alternative to subcutaneous immunotherapy, an alternative that might trigger fewer systematic reactions such as anaphylaxis.

Research indicates that patients with type 2 diabetics mellitus and low testosterone levels are 6 times more likely than those with normal testosterone levels to have increased carotid artery intima media thickness (CIMT) and decreased endothelial function.

Researchers from Germany believe they have improved upon current methods for diagnosing wheat-dependent exercise-induced anaphylaxis (WDEIA) - and demonstrated that the condition isn't necessarily induced by exercise.

Researchers have shown that testosterone replacement therapy reduces the complications associated with type 2 diabetes mellitus in androgen-deficient, overweight men.

Despite much evidence that atrial fibrillation (AF) greatly increases the risk of cognitive decline, a review of research to date finds little compelling support for any particular strategies to minimize that risk.

Why do some allergic reactions produce only relatively mild symptoms while others trigger anaphylaxis and eventual death?

Guidelines from the Endocrine Society report that postmenopausal women with hypoactive sexual desire disorder may benefit from up to 6 months of testosterone replacement therapy but recommend against its use in otherwise healthy women.

Analysis of insurance claims and medical records indicates that people with mitral annular calcification may face a greatly elevated risk of incident atrial fibrillation.

More than a dozen studies over the past few decades have undermined the once common fear that influenza vaccines containing egg proteins could induce reactions such as anaphylaxis in people with egg allergies.

A meta-analysis of many older studies may explain the recent observation that patients with atrial fibrillation (AF) frequently suffered cognitive impairment without suffering from any signs of stroke.

New research suggested that men with the sort of wider faces that indicate higher testosterone levels show greater dominance and fare better than narrow-faced men in negotiations.

New research suggests that a simple blood test could identify people with a genetic predisposition towards atrial fibrillation and justify prophylactic treatment to cost-effectively prevent strokes.

A new study indicates that medications produce far more fatal cases of anaphylaxis than either venom or food.

New research indicates that children who receive epinephrine injections before they go to the emergency room for food-related anaphylaxis are less than half as likely to require hospitalization as those who first receive such treatment at the hospital.

Analysis of a dozen phase III trials indicates that patients with atrial fibrillation face significantly less risk of major, fatal, and intracranial bleeding if they take target-specific oral anticoagulants rather than vitamin K antagonists.

New research provides some of the first concrete support for a treatment guideline that has long been recommended on grounds of common sense alone: Patients who suffer severe allergic reactions such as anaphylaxis should follow up on their emergency room care by seeing an allergist or immunologist.

New research into food-induced anaphylaxis concludes that hospitalization rates among American children roughly doubled between 2000 and 2009.

The American Association for Thoracic Surgery (AATS) has released new guidelines designed to prevent the occurrence of atrial fibrillation (AF) in thousands of patients who undergo lung surgery in the United States each year.
