Query: good concept, unfortunately not well done

After reading the other reviews and leafing through the online book pages, I thought this would be a great book to review as a medical student prior to the Shelf. However, going through just the second chapter resulted in numerous errors. The most glaring being the most likely cause of hypercalcemia, which was alleged to be familial hypercalcuria hypercalcemia (in reality it is parathyroid adenoma in the general population, malignancy in the hospital). This is a very basic question, which made me question the rest of the book. Leafing through other parts of the book, I found more errors, and have decided to return the book.Although the concept of the book is great, the author should have invested some time in fact-checking.
