Bell's Palsy: Diagnosis and Management - Article
ABSTRACT: Bell's palsy is a peripheral palsy of the facial nerve that results in muscle weakness on one side of the face. Affected patients develop unilateral facial paralysis over one to three days with forehead involvement and no other neurologic abnormalities. Symptoms typically peak in the first week and then gradually resolve over three weeks to three months. Bell's palsy is more common in patients with diabetes, and although it can affect persons of any age, incidence peaks in the 40s. Bell's palsy has been traditionally defined as idiopathic; however, one possible etiology is infection with herpes simplex virus type 1. Laboratory evaluation, when indicated by history or risk factors, may include testing for diabetes mellitus and Lyme disease. A common short-term complication of Bell's palsy is incomplete eyelid closure with resultant dry eye. A less common long-term complication is permanent facial weakness with muscle contractures. Approximately 70 to 80 percent of patients will recover spontaneously; however, treatment with a seven-day course of acyclovir or valacyclovir and a tapering course of prednisone, initiated within three days of the onset of symptoms, is recommended to reduce the time to full recovery and increase the likelihood of complete recuperation.
ABSTRACT: The sixth report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-VI) includes recommendations for the assessment of overall cardiovascular risk and the need for active antihypertensive drug therapy. Once the decision to initiate antihypertensive drug therapy has been made, JNC-VI recommends one of three paths for the choice of initial therapy: one path for patients with uncomplicated hypertension, another for those with well-defined indications for certain drugs and a third path for patients with various concomitant conditions in which one or another drug has favorable effects. At this time, the place for the newest class of antihypertensive drugs, the angiotensin II receptor antagonists, remains uncertain. Currently, they are considered reasonable alternatives for patients who have a compelling need for an angiotensin-converting enzyme (ACE) inhibitor but develop a cough while taking this medication. When data from ongoing trials become available, angiotensin II receptor antagonists may prove to be a good choice for initial therapy in many patients because of the favorable side effect profile of this class of drugs.
ABSTRACT: Angiotensin-II receptor antagonists (or blockers) are a newer class of antihypertensive agents. These drugs are selective for angiotensin II (type 1 receptor); unlike angiotensin-converting enzyme inhibitors, they do not inhibit bradykinin metabolism or enhance prostaglandin synthesis. Angiotensin-II receptor antagonists are well tolerated. Cough occurs much less often with these agents than with angiotensin-converting enzyme inhibitors, and they do not adversely affect lipid profiles or cause rebound hypertension after discontinuation. Clinical trials indicate that angiotensin-II receptor antagonists are effective and safe in the treatment of hypertension. Their use in congestive heart failure and renal disease is under investigation.
