WAlcohol flush reaction (AFR) is a condition in which a person develops flushes or blotches associated with erythema on the face, neck, shoulders, and in some cases, the entire body after consuming alcoholic beverages. The reaction is the result of an accumulation of acetaldehyde, a metabolic byproduct of the catabolic metabolism of alcohol, and is caused by an aldehyde dehydrogenase 2 deficiency.
WGastrointestinal diseases refer to diseases involving the gastrointestinal tract, namely the oesophagus, stomach, small intestine, large intestine and rectum, and the accessory organs of digestion, the liver, gallbladder, and pancreas.
WHemorrhoids, also spelled haemorrhoids, are vascular structures in the anal canal. In their normal state, they are cushions that help with stool control. They become a disease when swollen or inflamed; the unqualified term "hemorrhoid" is often used to refer to the disease. The signs and symptoms of hemorrhoids depend on the type present. Internal hemorrhoids often result in painless, bright red rectal bleeding when defecating. External hemorrhoids often result in pain and swelling in the area of the anus. If bleeding occurs it is usually darker. Symptoms frequently get better after a few days. A skin tag may remain after the healing of an external hemorrhoid.
WHeyde's syndrome is a syndrome of gastrointestinal bleeding from angiodysplasia in the presence of aortic stenosis.
WLymphocytic esophagitis is a rare and poorly understood medical disorder involving inflammation in the esophagus. The disease is named from the primary inflammatory process, wherein lymphocytes are seen within the esophageal mucosa. Symptoms of the condition include difficulty swallowing, heartburn and food bolus obstruction. The condition was first described in 2006 by Rubio and colleagues. Initial reports questioned whether this was a true medical disorder, or whether the inflammation was secondary to another condition, such as gastroesophageal reflux disease.
WA rectus sheath hematoma is an accumulation of blood in the sheath of the rectus abdominis muscle. It causes abdominal pain with or without a mass.
WReynolds syndrome is a rare secondary laminopathy, consisting of the combination of primary biliary cirrhosis and progressive systemic sclerosis. In some patients this syndrome has also been associated with Sjögren's syndrome and hemolytic anemia. Typical clinical features include jaundice, elevated blood levels of alkaline phosphatase, calcinosis cutis, telangiectasias, and pruritus. This disease may cause white or yellow-ish spots on the arms or legs. The syndrome, a special case of scleroderma, is named after the American physician, Telfer B. Reynolds, MD (1921–2004), who first described it. He is also known for creating one of the world's first hepatology programs at the University of Southern California.
