| neoplastic syndromes, hereditary | The condition of a pattern of malignancies within a family, but not every individual's necessarily having the same neoplasm. Characteristically the tumour tends to occur at an earlier than average age, individuals may have more than one primary tumour, the tumours may be multicentric, usually more than 25 percent of the individuals in direct lineal descent from the proband are affected, and the cancer predisposition in these families behaves as an autosomal dominant trait with about 60 percent penetrance.

| nerve compression syndromes | Repeated or prolonged pressure on a nerve root or peripheral nerve leading to ischemia, the response to which is oedema above and below the source of pressure. If the pressure is not relieved, fibrosis tends to develop. Types of nerve compression syndromes are the neuropathy caused by intervertebral disk herniation, compression of the median nerve in the carpal tunnel, compression of the ulnar nerve in the elbow, and compression of the lateral cutaneous nerve of the thigh in meralgia paresthetica. This is also called pressure neuropathy. (12 Dec 1998) |
| syndromes of paranasal sinuses | <radiology> Gardner: osteomas, Kartagener: chronic infection, basal cell-nevoid, neurofibromatosis, Down (trisomy 21): hypoplastic frontal, sphenoid, with or without ethmoid, progeria: absent frontal sinuses; dwarf, immature, cleidocranial dysostosis: all sinuses absent/small (12 Dec 1998) |
| dry eye syndromes | Corneal and conjunctival dryness due to deficient tear production, predominantly in menopausal and post-menopausal women. Filamentary keratitis or erosion of the conjunctival and corneal epithelium may be caused by these disorders. Sensation of the presence of a foreign body in the eye and burning of the eyes may occur. (12 Dec 1998) |
| immunologic deficiency syndromes | Syndromes in which there is a deficiency or defect in the mechanisms of immunity, either cellular or humoral. (12 Dec 1998) |
| overgrowth syndromes | Conditions with multiple abnormalities including excessive growth. Early overgrowth syndromes that affecting children include the fragile x and beckwith-wiedemannn syndromes. Overactivity of the pituitary gland with overproductiuon of growth hormone causes overgrowth before adolescence and a distinctive pattern of overgrowth called acromegaly. (12 Dec 1998) |
| euthyroid sick syndromes | Abnormalities in thyroid hormone and thyroid-stimulating hormone levels, often simulating hypothyroidism, in euthyroid patients suffering some other illness, such as diabetes mellitus or liver cirrhosis. (12 Dec 1998) |
| 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) |
