"Differential Diagnosis in Internal Medicine," by Dr. R. Hegglin, sees its aim in the selection and organization of medical knowledge for the practical purpose of bedside diagnosis.
Scientific completeness is not its object, since it cannot be realized by the physician in the sick-room.
The elements of the various branches of internal medicine, which are of importance in the diagnostic endeavors of the physician, are selected and presented in such a systematic manner that they can be utilized easily for the clinical problem at hand.
The general plan of the book is to start with the dominating symptom and, by integrations of additional manifestations and pathophysiological considerations, to arrive at the disease entity.
Reflections on the comparative "values" of symptoms and on the elements of the diagnostic process make for interesting and stimulating reading and show the philosophical inclinations and orientation of the European schools.
