President Obama denies North Korea can make a nuclear strike against the U.S. or its allies, claiming they cannot make a nuclear weapon miniaturized (small and lightweight enough) for missile delivery. The miniaturization myth never made sense technically and is contradicted by the defense community.
Causes of Esophageal Strictures. Esophagitis is the inflammation of the lining of the esophagus which often leads to swelling. Some of the common causes include chronic acid reflux (GERD / gastroesophageal reflux disease), infections or autoimmune causes (eosinophilic esophagitis).
When contractions in the esophagus become irregular, unsynchronized or absent, the patient is said to have esophageal dysmotility. The areas of dysfunction in the esophagus may be in the upper esophageal sphincter (UES), the body of the esophagus or the lower esophageal sphincter (LES). Oropharyngeal and UES dysfunction may be caused by neurologic and neuromuscular diseases or may be of unknown cause.
