A coordinated community response to cardiac arrest can be successful if the response time to administration of cardiopulmonary resuscitation (CPR) is less than four minutes and to administration of advanced cardiac life support (ACLS) is less than eight minutes. Elements needed to achieve this goal include rapid access to the emergency medical system; widespread CPR training; rapid response of first responders trained in basic life support; rapid response time to ACLS, including resuscitation at the scene; and an evaluation system to determine the effectiveness of the response and then implementation of changes to prevent future mistakes. ⋯ Most communities already have the necessary elements and simply need to coordinate the effort into a reasonable approach. Perhaps with such an approach, 80% of deaths from sudden cardiac arrest could be prevented.

Case Reports'Essential' hypertension with hypokalemia. Caused by aldosterone-secreting adrenal adenoma.
Primary aldosteronism is a potentially curable cause of hypertension; it occurs in about 1% of hypertensive patients. In the case reported here, persistent hypokalemia developed in a 72-year-old man who had been treated for 13 years for essential hypertension. ⋯ Aldosterone-secreting adenoma of the adrenal gland was diagnosed, and right adrenalectomy was performed. At a six-month follow-up examination, the patient's blood pressure and potassium level were normal.

Imported fire ant allergy. Perspectives on diagnosis and treatment.
As the imported fire ant relentlessly expands its territory, more and more people are at risk of the insects' discomforting and sometimes dangerous stings. Thus, all primary care physicians in fire ant-infested areas should be familiar with diagnosis and treatment of fire ant stings and of allergic reactions to the stings. ⋯ Diagnosis of fire ant allergy can be readily made by the radioallergosorbent test (RAST) or by skin testing using fire ant wholebody extract. Immunotherapy with fire ant whole-body extract in allergic individuals can prevent serious recurrent systemic reactions.
