Patients who have high-grade tumours, are symptomatic, or have poor life expectancy can also be maintained on dexamethasone 0.5–1.0 mg daily after radiotherapy. All patients should be observed for symptoms of adrenal insufficiency if dexamethasone is discontinued abruptly or used for a prolonged time, and advice from an endocrinologist should be sought if needed.

Diagnosing high blood pressure Your blood pressure varies from day to day, even from moment to moment. Generally, if a person has a blood pressure reading taken on 3 separate occasions that is greater than 140/90, they have high blood pressure.
Conversely, measuring blood pressure 5 mm Hg too high would falsely classify 27 million persons as having [hypertension]. At the cost of $1,000 per year to treat a patient, this would add $27 billion to the Nation’s health care bill to treat a nondisease” (3).

Pressure-treated luer is ideal for outdoor construction as it has a long, useful life span and is much less expensive than alternatives. Treated wood can last more than 40 years. The treatment process involves placing a load of luer in a huge cylindrical chaer called a retort with a door on one end that can be sealed airtight, and then forcing waterborne chemicals into the wood under

While newer high-strength concretes can resist higher levels of pressure than older mixtures, they still can be susceptible if cracks form or hydrostatic pressure builds high enough. Hydrostatic pressure is a natural force that can move rocks, buckle walls, and cause havoc with your concrete, but it does not explain every instance of water intrusion in concrete.
