| benign headache | A benign form of headache that results from the painful spasm (muscle tightness) and inflammation of muscles of the head and neck. Tension headache is one of the most common forms of headache. Spasm and contraction of the head and neck muscles may occur in response to fatigue, overuse, eye strain, excessive smoking, stress, anxiety or depression. Sleeping in an abnormal position or prolonged work involving immobilisation of the neck in one position (typing, computers, etc.) are considered common triggers. Exercising and stretching the muscles of the head and neck can reduce the occurrence of muscle tension headaches. (27 Sep 1997) |
| benign hypertension | Hypertension that runs a relatively long and symptomless course. (05 Mar 2000) |
| benign inoculation lymphoreticulosis | <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) |
