| chromosomal instability syndromes | A group of mendelian conditions associated with chromosomal instability and breakage in vitro, they often manifest an increased tendency to certain types of malignancies. See: Bloom's syndrome, fragile X syndrome, xeroderma pigmentosum. (05 Mar 2000) |
|---|---|
| compartment syndromes | Conditions in which increased pressure within a limited space compromises the circulation and function of tissue within that space. Compartmentation involves mainly the leg but also involved are the forearm, arm, thigh, shoulder, and buttock. Some of the causes of increased pressure are trauma, tight dressings, haemorrhage, and exercise. Sequelae include nerve compression, paralysis, and contracture. (12 Dec 1998) |
| myelodysplastic syndromes | Conditions in which the bone marrow shows qualitative and quantitative changes suggestive of a preleukaemic process, but having a chronic course that does not necessarily terminate as acute leukaemia. (12 Dec 1998) |
| myeloproliferative syndromes | A group of conditions that result from a disorder in the rate of formation of cells of the bone marrow, including chronic granulocytic leukaemia, erythraemia, myelosclerosis, panmyelosis, and erythraemic myelosis and erythroleukaemia. (05 Mar 2000) |
| myofascial pain syndromes | Muscular pain in numerous body regions that can be reproduced by pressure on trigger points, localised hardenings in skeletal muscle tissue. Pain is referred to a location distant from the trigger points. A prime example is the temporomandibular joint dysfunction syndrome. (12 Dec 1998) |
| postgastrectomy syndromes | Sequelae of gastrectomy from the second week after operation on. Include recurrent or anastomotic ulcer, postprandial syndromes (dumping syndrome and late postprandial hypoglycaemia), disordered bowel action, and nutritional deficiencies. (12 Dec 1998) |
| pre-excitation syndromes | Conditions characterised by activation of the whole or some part of the ventricle by the atrial impulse earlier than would be expected if the impulse reached the ventricle by way of the normal specific conduction system only. (12 Dec 1998) |
| sleep apnea syndromes | Disorders involving apneic episodes during sleep. They may be due to cessation of diaphragmatic movement, obstruction of upper airway air flow, or a combination of these, and may be associated with hypersomnolence, insomnia, or obesity. (12 Dec 1998) |
| neoplastic endocrine-like syndromes | Endocrine syndromes due to hormone production by neoplasms of non-endocrine tissue, or by other than the usual endocrine tissues. They are often the first indication of a previously undetected neoplasm. (12 Dec 1998) |
| 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. (12 Dec 1998) |
| 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) |
