| nodular headache | Radiating pain in the head accompanied by nodular swellings in the splenius, frontalis, trapezius, and other muscles. (05 Mar 2000) |
| symptomatic headache | A headache secondary to another organic condition. Synonym: reflex headache. (05 Mar 2000) |
| organic headache | Headache due to intracranial disease. (05 Mar 2000) |
| tension headache | <neurology> 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. (13 Jan 1998) |
| fibrositic headache | Headache centreed in the occipital region due to fibrositis of the occipital muscles; tender areas are present and, commonly, tender nodules are found in the scalp in the lower occipital region. (05 Mar 2000) |
| anaemia of chronic disease | <disease> A form of anaemia which develops as the result of a long-term infection or illness. Chronic diseases can interfere with red blood cell production in addition to shortening red blood cell life span in the body. Symptoms are largely due to the underlying disease. Haemoglobin and haematocrit are generally low. Iron studies may be low to normal. Red blood cell indices may usually normal. (27 Sep 1997) |
| benign familial chronic pemphigus | Recurrent eruption of vesicles and bullae that become scaling and crusted lesions with vesicular borders, predominantly of the neck, groin, and axillary regions; autosomal dominant inheritance, presenting in late adolescence or early adult life. Synonym: Hailey-Hailey disease. (05 Mar 2000) |
| candidiasis, chronic mucocutaneous | A clinical syndrome characterised by development, usually in infancy or childhood, of a chronic, often widespread candidiasis of skin, nails, and mucous membranes. It may be secondary to one of the immunodeficiency syndromes, inherited as an autosomal recessive trait, or associated with defects in cell-mediated immunity, endocrine disorders, dental stomatitis, or malignancy. (12 Dec 1998) |
| granulomatous disease, chronic | A recessive x-linked defect of leukocyte function in which phagocytic cells ingest but fail to digest bacteria, resulting in recurring bacterial infections with granuloma formation. (12 Dec 1998) |
| persistent chronic hepatitis | A benign chronic hepatitis that may follow acute viral hepatitis A or B, or complicate bowel diseases; after six months, liver biopsy changes are mild, unlike active chronic hepatitis; rarely, if ever, progresses to cirrhosis, portal hypertension, or liver failure. (05 Mar 2000) |
| chronic | Persisting over a long period of time. Origin: L. Chronicus, Gr. Chronos = time (18 Nov 1997) |
| chronic abscess | A long-standing collection of pus surrounded by fibrous tissue. (05 Mar 2000) |
| chronic absorptive arthritis | Arthritis accompanied by pronounced resorption of bone with shortening and deformity, especially of the hands; when the deformity is extreme, the condition has also been termed arthritis mutilans. (05 Mar 2000) |
| chronic acholuric jaundice | <haematology> A hereditary disorder that leads to a chronic haemolytic anaemia due to an abnormality in the red blood cell membrane. This disorder is caused by a defective gene. Red cells are resistant to stress and rupture easily. Infants may appear jaundiced and pale. Fatigue, weakness and shortness of breath are other symptoms that may be seen in older patients. The spleen may also be enlarged. Treatment includes splenectomy (removal of the spleen). After this is accomplished the life-span of the red blood cells returns to normal. (27 Sep 1997) |
