I have NEVER had a more useful text in my office!! Gives a clear approach to common and often complex problems faced in outpatient and inpatient medicine. Includes topics such as thyroid nodule, hyponatremia (and other electrolyte abnormalities), elevated transaminases, fatigue, chronic diarrhea, constipation, solitary pulmonary nodule, mediastinal adenopathy, and really anything else you can think of!! I have never not been able to find what I needed quickly and easily. A must have for an busy office when you need to know what to do without all the peripheral talk!! I wish they had continue this series in Peds and OB/Gyn (there are old ones in these fields)as they were just as valuable!! An investment you won't regret. Great for residents!!
