| regional granulomatous lymphadenitis | <disease> A self-limiting bacterial infection of the regional lymph nodes (lymphadenitis) caused by afipia felis, a gram-negative bacterium recently identified as bartonella henselae. It usually arises one or more weeks following a feline scratch, with raised inflammatory nodules at the site of the scratch being the primary symptom. It results in tender and enlarged lymph glands above the site of injury. A chronic benign adenopathy, especially in children and young adults, commonly associated with a recent cat scratch or bite and caused by bacteria including Bartonella henselae and Alipia felis; the lymphadenopathy usually resolves spontaneously within a period of several months, but complications involving central nervous system, liver, spleen, lung, and skin have been seen. Synonym: benign inoculation lymphoreticulosis, benign inoculation reticulosis, cat-scratch fever, regional granulomatous lymphadenitis. (05 Mar 2000) |

| enteritis, regional | Crohn's disease by another name, a chronic inflammatory disease of the intestine primarily in the small and large intestines but which can occur anywhere in the digestive system between the mouth and the anus. Named after Burrill Crohn who described the disease in 1932. The disease usually affects persons in their teens or early twenties. It tends to be a chronic, recurrent condition with periods of remission and exacerbation. In the early stages, Crohn's disease causes small scattered shallow crater-like areas (erosions) called apthous ulcers in the inner surface of the bowel. With time, deeper and larger ulcers develop, causing scarring and stiffness of the bowel and the bowel becomes increasingly narrowed, leading to obstruction. Deep ulcers can puncture holes in the bowel wall, leading to infection in the abdominal cavity (peritonitis) and in adjacent organs. When only the large intestine (colon) is involved, the condition is called Crohn's colitis. When only the small intestine is involved, the condition is called Crohn's enteritis. When only the end of the small intestine (the terminal ileum) is involved, it is termed terminal ileitis. When both the small intestine and the large intestine are involved, the condition is called Crohn's enterocolitis (or ileocolitis). Abdominal pain, diarrhoea, vomiting, fever, and weight loss can be symptoms. Crohn's disease can be associated with reddish tender skin nodules, and inflammation of the joints, spine, eyes, and liver. Diagnosis is by barium enema, barium X-ray of the small bowel, and colonoscopy. Treatment includes medications for inflammation, immune suppression, antibiotics, or surgery. (The disease is also called granulomatous enteritis). (12 Dec 1998) |
