To effectively combat an infection, the body first has to sense it’s been invaded, then the affected tissue must send out signals to corral resources to fight the intruder. Knowing more about these early stages of pathogen recognition and response may provide scientists with crucial clues when it comes to preventing infections or treating inflammatory
About one in 100 children has a common brain disorder called Chiari 1 malformation, but most of the time such children grow up normally and no one suspects a problem. But in about one in 10 of those children, the condition causes headaches, neck pain, hearing, vision and balance disturbances, or other neurological symptoms. In

Gastroesophageal Reflux Disease, or GERD, is often the result of a hiatal hernia or weakness of the valve called the lower esophageal sphincter. Over time, reflux can lead to Barretts esophagus, dysplasia and even esophagus cancer (adenocarcinoma.) This video shows how an operation called fundoplication can help prevent acid from splashing into the esophagus. Mayo
