Addisonian Crisis: From 1 Different Sources
an acute medical emergency due to a lack of corticosteroid production by the body, caused by disease of the adrenal glands or long-term suppression of production by steroid medication. It manifests as low blood pressure and collapse, biochemical abnormalities, hypoglycaemia, and (if untreated) coma and death. Treatment is with steroids, administered initially intravenously in high doses and later orally. In patients with poor adrenal function an Addisonian crisis is usually brought on by an acute illness, such as an infection. [T. Addison (1793–1860), British physician]
Crisis is a word used with several distinct meanings. (1) The traditional meaning is that of a rapid loss of fever and return to comparative health in certain acute diseases. For example, PNEUMONIA, if allowed to run its natural course, ends by a crisis usually on the eighth day, the temperature falling in 24 hours to normal, the pulse and breathing becoming slow and regular and the patient passing from a partly delirious state into natural sleep. In this sense of the word, the opposite of crisis is lysis: for example, in typhoid fever (see ENTERIC FEVER), where the patient slowly improves during a period of a week or more, without any sudden change. (2) A current use of the word crisis, and still more frequently of critical, is to signify a dangerous state of illness in which it is uncertain whether the sufferer will recover or not.... crisis

acute obstruction of a kidney causing severe pain in the loins. The obstruction usually occurs at the junction of the renal pelvis and the ureter, causing the kidney to become distended with accumulated urine (see hydronephrosis). Sometimes the pelvis drains spontaneously, with relief of pain, but acute decompression of the kidney may be required with surgical relief of the obstruction (*pyeloplasty). [J. Dietl (1804–78), Polish physician]... dietl’s crisis
(thyroid storm) a life-threatening condition due to an acute and severe exacerbation of previously undiagnosed or inadequately treated *thyrotoxicosis. It often follows infections, childbirth, nonthyroid surgery, or trauma but can occur without an obvious cause. The presenting features are a fever, severe agitation, nausea and vomiting, diarrhoea, and abdominal pains. An accelerated heart rate and irregularity of the heart rhythm can cause heart failure, and psychotic episodes or coma can result. Blood tests will reveal hyperthyroidism and may also show altered liver function, high blood sugar, high calcium levels, a high white blood cell count, and often anaemia. Treatment is with intravenous fluids, oxygen, antithyroid drugs (such as *carbimazole or *propylthiouracil), high-dose iodide solution (see Lugol’s solution), high-dose steroids, and beta blockers. The patient must be cooled and given antipyretics, such as paracetamol. Any underlying cause must also be treated.... thyroid crisis
