Havinghad the pleasureto teach and train students for many years,andthe privilegeofhaving patients referred to
me by ex-student General Practitioners,one realizesthat medical school training can only impart but a general
overview of knowledge.lt is impossibleand unfair to expect of any medical student to "know it all".
For this reason continuing medical education,or Continuing ProfessionalDevelopment (CPD) as it is now known
in South Africa, is imperative.
This post-graduatetraining should however, be presented in such a way that the busy practitioner readily has
accessto the relevant information in a succinct form and in an understandablejargon.
Communication between the referring doctor and the specialistshould not only include information regarding
that particular patient, but should also contain some informative detail on the pathology and management.
This continuing education is part of the responsibilitiesof a consultant specialist.
It is sincerelyhoped that this edited collection of selectedcasereports will promote a well-informedcommunication
between the practitioner and his/her "hand patient".
