How expensive? Study results show that families with children who are allergic to staple food items pay out thousands of extra dollars each year in direct and indirect costs.

Earlier this year, a skin patch designed to reduce the risk of anaphylaxis and other severe reactions to peanuts became the first allergy treatment ever granted a Breakthrough Therapy Designation by the FDA.

A clinical trial with a choline-rich structured lipid found that daily intake can significantly reduce choline depletion in cystic fibrosis patients with exocrine pancreatic insufficiency.

A large retrospective analysis from Canada suggests that dabigatran is about as safe and effective as warfarin in elderly patients with atrial fibrillation.

A new study from Korea indicates that children who undergo pylorus-preserving pancreaticoduodenectomy (PPPD, aka the Whipple Procedure) generally avoid problems such as exocrine pancreatic insufficiency and lead relatively normal lives.

Over the past year, school officials in several of the nation's largest states have implemented new policies to address the growing prevalence and severity of pediatric allergies by increasing access to epinephrine auto-injectors.

New research into distal pancreatectomies indicates that women and overweight patients have an elevated risk of suffering endocrine function impairment that leads to glucose intolerance and diabetes mellitus.

New research suggests that cold weather may be an underappreciated hazard for patients with atrial fibrillation.

New research on the link between diabetes and pancreatitis has shown a strong association between the severity of pancreatic dysfunction and subsequent risk of developing type 2 diabetes mellitus.

New research concludes that the association between celiac disease and exocrine pancreatic insufficiency (EPI) is strong enough that physicians should check for EPI when celiac patients suffer malnutrition or gastric distress despite adherence to prescribed diets.

At least 5 studies indicating that testosterone replacement therapy either has no effect on cardiovascular health -- or tends to improve it -- appeared during the 3-week period immediately after the US Food and Drug Administration's controversial decision to mandate warnings about the potential cardiovascular risks of such treatment.

Researchers have long known that single men tend to have more testosterone than comparable men in long-term relationships, but what about men in new relationships? A new study finds that testosterone generally remains at "single-man" levels until couples have been dating for more than a year.

The increasing prevalence of food allergies (along with increasing awareness of the dangers associated with those allergies) has famously led to food restrictions in schools and on commercial airlines. The trend has now spread to a venue that's strongly associated with the enjoyment of fresh roasted peanuts: baseball stadiums.

The US Food and Drug Administration has warned physicians that it may be dangerous to use a device known as the Lariat to close the left atrial appendage in patients with heart arrhythmias.

Research using mouse models may offer clues to potential prophylactic approaches for patients with venom sensitivity.

New research may help explain the connection between exocrine pancreatic insufficiency, gastric bypass surgery, and oxalate nephropathy in humans.

Recent studies of anaphylaxis and other allergic reactions induced by medications have informed a new set of guidelines for the diagnosis and treatment drug hypersensitivity.

Data from two observational registries indicated that long-term testosterone replacement therapy in diabetic men was associated not only with better sexual function and weight loss, but also significant reductions in blood sugar.

A small study of children with cystic fibrosis found ghrelin and leptin levels correlate with nutritional status and can be an early marker of exocrine pancreatic insufficiency.

Researchers have shown that the tendency of atrial fibrillation to impair cognitive function stems, at least in part, from a reduction in blood flow to the brain.

New research finds that low testosterone levels are strongly associated with low bone density (BMD) - even in relatively young men.

A new analysis has found that low levels of vitamin D are independently associated with low levels of testosterone in healthy middle-aged men.

Results from a Japanese study show that testosterone replacement therapy may improve nocturia, sleep conditions, and quality of life among men with hypogonadism and nocturia.

Results from 2 trials presented at the recent Heart Rhythm Society meeting suggest that 2 alternative ablation technologies work about as well as those that are commonly used on patients with atrial fibrillation.

A new review of existing research on hypogonadism suggested that testosterone replacement therapy can ameliorate the morbidity associated with renal failure in many men.

Exposure to electromagnetic fields had been recently found to reduce the amount of testosterone men produce, potentially reducing their fertility.

New research indicated adolescents are twice as likely as younger kids to suffer from anaphylaxis and other severe allergic reactions while they are in school.

A study of men with borderline testosterone levels found that half of them suffered either depressive symptoms or overt depression.

Analysis of a large patient cohort indicates that "isolated" events of atrial fibrillation precipitated by temporary secondary conditions tend to become chronic long-term cases of atrial fibrillation.

FDA approval of the left atrial appendage closure device after a long review process provides a potentially useful alternative to warfarin.
