The term Cushing's disease is applied to those cases of Cushing's syndrome in which hypercortisolism is secondary to inappropriate secretion of ACTH by the pituitary. Studies on control of ACTH secretion in these patients reveal: (a) that the episodic secretion of ACTH is similar to the normal; however, frequency and amplitude of the secretory ...

Cushing's Triad occurs when there is increased intracranial pressure (ICP), which results in irregular breathing, hypertension, and bradycardia. So let us kick this thing off with a scenario. A 40 year old male was assaulted with a metal bat. When you make contact, bystanders say he was hit in the head and is confused.

Cushing's triad usually occurs in the late stages of acute head injury. This reflex is usually a normal homeostatic response of the body to prevent brain ischemia. But, unfortunately, this triad is a late indication of increased intracranial pressure. Moreover, this triad also suggests that brainstem herniation is possible.
Cushing's triad is the manifestation of Cushing reflex (also referred to as the Cushing effect, the Cushing reaction, the Cushing's phenomenon, or Cushing's Law) – physiological nervous system response to increased intracranial pressure. Cushing's triad is also known as the brain herniation triad. It is the signs/symptoms developed by ...
The Cushing's triad is related to the degree of herniation on the pons. This area of the brain stem is where the chemoreceptors (respiratory center), baroreceptors (blood pressure), and cardiac center (heart rate) are found. At the top of this progression is the level of consciousness. As the brain stem herniates, the pressure shuts down the ...
Damage to the endothelial wall of a vessel alters the dynamics of blood flow. Endothelial disturbance can result from insults such as smoking, chronically elevated blood pressure, and atherosclerotic disease secondary to hyperlipidemia. When an insult to the wall occurs, flow disruption or "turbulence" occurs.

Cushing syndrome, first described by Harvey in 1912, refers to signs and symptoms caused by excess free plasma glucocorticoids. Excess glucocorticoids can be from increased endogenous production or...
Hence, the diagnosis of Cushing disease is a rigorous process often requiring confirmatory tests at each step and endocrine consultation. A simplified diagnostic approach is delineated in Fig. 1 ...
Diagnosis. Taking glucocorticoid medications is the most common cause of Cushing syndrome. Your doctor can review all your medications — pills, injections, creams and inhalers — to determine if you're taking medications that can cause the disorder. If you are, you probably won't need other tests. Cushing syndrome from endogenous cortisol ...
Cushing's triad, consisting of bradycardia, irregular respirations, and widened pulse pressures, is the body 's response to increased intracranial pressure (ICP). It usually indicates a severe lack of oxygen in the brain tissue. The Cushing reflex and subsequent triad are the body 's final attempts to oxygenate the brain and prevent infarction.
McCune-Albright syndrome (MAS) consists of at least two of the following three features: (1) polyostotic fibrous dysplasia (PFD), (2) café-au-lait skin pigmentation (see the image below), and (3) autonomous endocrine hyperfunction (eg, gonadotropin-independent precocious puberty).Other endocrine syndromes may be present, including hyperthyroidism, acromegaly, …

Most cases of Cushing syndrome are due to exogenous glucocorticoids. The annual incidence of endogenous Cushing syndrome has been estimated at 13 cases per million individuals. Of these cases, approximately 70% are due to Cushing disease, that is, a pituitary ACTH-producing tumor; 15% to ectopic ACTH; and 15% to a primary adrenal tumor.

Cushings isn't a condition that requires treatment. It is a set of symptoms that are a physiologic response to brain herniation secondary to increased intracranial pressure. The best thing you can do is support their respiration's and effectively alert your receiving facility of the severity of the pt and their symptoms.
This activity is intended for primary care physicians, endocrinologists, neurosurgeons, nurses, pharmacists and other specialists who care for patients with Cushing disease. The goal of this activity is to provide comprehensive, evidence based information in a readily accessible format to healthcare professionals in order to enhance patient care.

The diagnostic approach to patients with suspected Cushing's syndrome has been published in an evidence-based guideline by the Endocrine Society. Three diagnostic studies are currently recommended: late-night salivary cortisol, 24 hour urine free cortisol, low-dose dexamethasone suppression. If any of these tests is abnormal, a referral to an ...
