Dexamethasone suppression tests are used to assess the status of the hypothalamic-pituitary-adrenal (HPA) axis and for the differential diagnosis of adrenal hyperfunction. The low-dose dexamethasone suppression tests are used to assess nonsuppressible cortisol production by adrenal incidentalomas and to differentiate patients with Cushing's syndrome of any cause from patients who do not have Cushing's syndrome. The high-dose dexamethasone suppression tests help to distinguish patients with Cushing's disease (Cushing's syndrome caused by pituitary hypersecretion of corticotropin [ACTH]) from most patients with the ectopic ACTH syndrome (Cushing's syndrome caused by nonpituitary ACTH-secreting tumors).

Fortunately, effective stress-management strategies can diminish the ill effects of stress. The presence of intact, strong, supportive social support networks among friends, family, educational and religious or other group affiliations can help reduce the subjective experience of stress during the teen years. Recognition of the problem and helping teens develop stress-management skills can also be valuable preventive measures. In severe cases, a physician or other health-care professional can recommend counseling or other treatments that can reduce the long-term risks of teen stress.

Corticosteroids are generally teratogenic in laboratory animals when administered systemical-ly at relatively low dosage levels. The more potent corticosteroids have been shown to be ter-atogenic after dermal application in laboratory animals. There are no adequate and well-controlled studies in pregnant women on teratogenic effects from topically applied corticosteroids. Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Drugs of this class should not be used extensively on pregnant patients, in large amounts, or for prolonged periods of time.

Treat infection if present; discontinue if infection persists or worsens. Do not use near eyes, or on diaper dermatitis or pre-existing skin atrophy. Do not use fluorinated steroids longer than 1 week on the face. Avoid abrupt cessation in chronic use. Systemic absorption increased by broken or inflamed skin, prolonged use, application to large surface area, or use of occlusive dressings. Occlude only if necessary; do not occlude higher potency products. Monitor adrenal function in children if a high potency product or occlusion is used, and in adults if more than 50g weekly of a high potency product is used. Discontinue or reduce dose or potency if HPA axis suppression, Cushing's syndrome, hyperglycemia, glucosuria, or irritation occurs. Use lowest effective dose and potency (esp. in children). Use caution if applying to face or body folds. Do not use continuously or for prophylaxis. Foams are flammable. Reevaluate periodically. Pregnancy (). Nursing mothers.

The hypothalamus senses low circulating levels of thyroid hormone (Triiodothyronine (T3) and Thyroxine (T4)) and responds by releasing thyrotropin-releasing hormone (TRH). The TRH stimulates the pituitary to produce thyroid-stimulating hormone (TSH). The TSH, in turn, stimulates the thyroid to produce thyroid hormone until levels in the blood return to normal. Thyroid hormone exerts negative feedback control over the hypothalamus as well as anterior pituitary, thus controlling the release of both TRH from hypothalamus and TSH from anterior pituitary gland.
