If you are a long-time reader of this journal, you may rememberthe photographs of authors that once gracedthe cover of every issue of Consultant. The May 1979issue of Consultant featured the picture of Donald Vidtyou see here; for that issue, Dr Vidt wrote “FiveMajor Vasodilators: How They Work” and advised readersabout the cardiovascular and renal hemodynamics ofhydralazine, prazosin, diazoxide, nitroprusside, and (atthat time the investigational agent) minoxidil. A quarter of a century later,Dr Vidt is still writing on the treatment of hypertension for readers of thisjournal-and it is with real pleasure that we introduce him here as a memberof our editorial board.
A 12-year-old black girl is hospitalized because of increasinglysevere dyspnea and sore throat. The sorethroat started about a week earlier and was accompaniedby fever and chills.

Heart failure statistics are daunting:550,000 new cases each year, a 1-yearmortality rate of nearly 20%, and annualdirect and indirect costs that total $24.3billion.1 The diverse etiology of heartfailure and the complex, progressivecourse of the disease can make treatmentdecisions daunting as well.
The US Preventive Services Task Force (USPSTF) recentlydetermined that there is insufficient evidence (Table) toeither recommend or discourage the use of vitamin supplementsto prevent cancer or cardiovascular disease.1 The useof supplements for other purposes was not included in theanalysis.

Twenty-four-hour ambulatory blood pressure (BP) monitoringis a more accurate predictor of stroke and myocardialinfarction than office BP measurement, according tothe results of the recent Office Versus Ambulatory BloodPressure Study. This prospective trial followed 1963 patientswith treated hypertension for 5 years.
Prolonged exposure to coldtemperatures can have a profoundeffect on the skin.When tissues are exposed toabove-freezing temperatures,localized vasoconstriction and increasedblood viscosity reduce bloodflow and decrease the amount ofoxygen available to tissues. Whentissues are exposed to freezing temperatures,water within those tissueschanges into ice crystals; this resultsin either intracellular or extracellulardamage and tissue necrosis.
