There are four sections in this book. First, we approach some general antifungal agent
issuesfromthehistoryofantifungal,fungalepidemiology,antifungalagentpreclinicaldevel-
opmenttodrugresistance.Second,weexamineindepththeantifungalclassesofdrugs,Third,
thereisanattempttoprovideclinicalmanagementissuesandstrategiesaroundspecificfungal

tionintheirpractice.Inthesesectionsthereareinsightsprovidedintodosing,choiceofdrugs,
concerns about complications and outcome which are both evidence—based but mixed with
personal opinions and experiences. Fungal infections are treated “one patient at a time” and
thereisno“cookbookrecipe”thatfitsallpatientsallthetime.Infact,theunderlyingdisease
simplygetsinthewaytoooftenorourevidence-basedmaterialiseitherweakornon-existent.
Finally, we conclude with management of several risk groups or unique patient populations
or infection sites and their fungal infections. It is not an exhaustive list but provides illustra-
tiveexposuretothesepatientsbutalsolaysthegroundwork/foundationfortheprinciplesof

Fungaldiseaseshaverisentoprominenceoverthelast50years.Theyhaveparalleledthe

exposed to millions of them. During health they are rarely a problem for us and after death
they degrade us. Many of our critical exposures for health and fungi come between these
stations of life. It is in this arena as a “human petri dish” that fungal disease raises its ugly
consequences. It is the hope of these authors that this book reveals the tools, strategies, and
insightstomanagetheseirritating,costlyandlife-threateninginfections.Attimes,itmayseem
