| salt-depletion crisis | Severe illness resulting from loss of sodium chloride, usually in urine (i.e., salt-losing nephritis), in sweat following severe exercise in hot weather, or in intestinal secretions, as in cholera. Can occur as result of Addison's disease or Addisonian crisis; characterised by hypovolaemia, hypotension. (05 Mar 2000) |

| sickle cell crisis | <haematology> Disease common in races of people from areas in which malaria is endemic. The cause is a point mutation in the allele that codes for the beta chain of haemoglobin with a substitution of (valine for glutamic acid at position 6. The defective haemoglobin (HbS) crystallizes readily at low oxygen tension. In consequence, erythrocytes from homozygotes change from the normal discoid shape to a sickled shape when the oxygen tension is low and these sickled cells become trapped in capillaries or damaged in transit, leading to severe anaemia. In heterozygotes, the disadvantages of the abnormal haemoglobin are apparently outweighed by increased resistance to Plasmodium falciparum malaria, probably because parasitised cells tend to sickle and are then removed from circulation. Symptoms include joint pain, acute abdominal pain, and ulcerations of the lower extremities. Origin: Gr. Haima = blood (18 Nov 1997) |
| Dietl's crisis | Intermittent pain, sometimes with nausea and emesis, caused by intermittent proximal obstruction of ureter. Originally believed due to a mobile kidney that caused ureter to kink with positional changes. Synonym: incarceration symptom. (05 Mar 2000) |
| identity crisis | <psychology> Chaotic concept of self wherein one's role in life appears to be an insoluble dilemma often expressed by isolation, withdrawal, rebellion and extremism. (12 Dec 1998) |
| ocular crisis | Sudden and severe pain in the eyes. (05 Mar 2000) |
| tabetic crisis | A sudden paroxysmal intensification of symptoms in the course of a disease. Origin: L., Gr. Krisis (18 Nov 1997) |
| therapeutic crisis | A turning point leading to positive or negative change in psychiatric treatment. (05 Mar 2000) |
| thyrotoxic crisis | Thyroid crisis, the exacerbation of symptoms that occurs in severe thyrotoxicosis; can follow shock or injury or thyroidectomy; marked by rapid pulse (140 to 170 per minute), nausea, diarrhoea, fever, loss of weight, extreme nervousness, and a sudden rise in the metabolic rate; coma and death may occur; occasionally the entire clinical picture is that of profound prostration, weakness, and collapse, without the phase of muscular overactivity and tachycardia. Synonym: thyroid storm. (05 Mar 2000) |
| febrile crisis | The stage in a febrile disease when spontaneous defervescence occurs. (05 Mar 2000) |
| laryngeal crisis | An attack of paralysis of the abductor, or spasm of the adductor, muscles of the larynx with dyspnea and noisy respiration, occurring in tabetic neurosyphilis. (05 Mar 2000) |
| accessory thyroid | An isolated mass, or one of several such masses, of thyroid tissue, sometimes present in the side of the neck, or just above the hyoid bone (suprahyoid accessory thyroid gland), or even as low as the arch of the aorta. Synonym: glandula thyroidea accessoria, accessory thyroid, prehyoid gland, suprahyoid gland, thyroidea accessoria, thyroidea ima, Wolfler's gland. (05 Mar 2000) |
| accessory thyroid gland | An isolated mass, or one of several such masses, of thyroid tissue, sometimes present in the side of the neck, or just above the hyoid bone (suprahyoid accessory thyroid gland), or even as low as the arch of the aorta. Synonym: glandula thyroidea accessoria, accessory thyroid, prehyoid gland, suprahyoid gland, thyroidea accessoria, thyroidea ima, Wolfler's gland. (05 Mar 2000) |
| anaplastic carcinoma of the thyroid | <oncology, tumour> An aggressive form and rare form of thyroid cancer that is one of the most rapidly growing and invasive types of thyroid cancer. It commonly occurs in people over 60 years of age and may cause obstruction of the trachea. The cause is unknown but exposure to radiation may be a factor. Thyroid function tests are usually normal. Hoarse voice, cough and coughing up blood are common symptoms. Examination may reveal nodules in the thyroid gland. Diagnosis is made via biopsy. Treatment is surgical with or without radiation therapy. (27 Sep 1997) |
| cancer, thyroid | Cancer of the gland in front of the neck that normally produces thyroid hormone which is important to the normal regulation of the metabolism of the body. There are four major types of cancer of the thyroid gland. Persons who received radiation to the head or neck in childhood should be examined by a doctor every 1 to 2 years. The most common symptom of thyroid cancer is a lump, or nodule, that can be felt in the neck. The only certain way to tell whether a thyroid lump is cancer is by examining the thyroid tissue obtained using a needle or surgery for biopsy. (12 Dec 1998) |
| receptors, thyroid hormone | Proteins, usually found in the nucleus, that specifically bind thyroid hormones and regulate DNA transcription. These proteins, termed c-erba, are activated by hormones and cause differentiation of erythroid progenitor cells which irreversibly lose proliferative potential. Thus c-erba proteins act as growth suppressors. The c-erba proteins are encoded by at least two genes, c-erba alpha and c-erba beta. Each of these has two isoforms. Mutations in the ligand-binding domain of the beta form causes thyroid hormone resistance syndrome. (12 Dec 1998) |
