From the outset it should be made clear that by the very nature of the title of this text being 'At a Glance', this title does not intend to give you all the information that you need to know on each of the conditions that is covered. The aim of this title as is the aim of the rest of the series, is that you should be able to get a good grounding in the knowledge that you will need to get you through and to excel in your medical student exams, most especially in the case of this title your finals.
The great advantage for the student purchasing this cases book however is the inclusion of a vast number of cases for you to walk through which are highly similar to those presented in the examination setting. The cases themselves are brief patient vignettes being up to 30 words in length in most cases but also including where relevant examination findings & a few high quality images. The questions that you are given on these cases are multiple choice ones and go through the full management of the conditions as would be the case in the exam. The answers section that follows gives you succinct answers & explanations along with a link for where to go and read some more detail in the Medicine at a Glance.
I would tend to agree that the whole of the 'at a Glance' series does use a disappointingly small amount of images in the texts, even when it would be highly appropriate to and would greatly enhance the quality of the text for it's certainly true in some cases that a 'picture can say a thousand words' in medicine. Yes there could be more differential diagnoses by some of the conditions in this title but you do have to draw a line somewhere and this title seems to do it well, if you've used another title such as above to gain your core knowledge then this should not pose a challenge.
In conclusion I would say that if you are preparing for your exams and want a book that will allow you to assess your knowledge then this title should certainly be considered. The main competitor to this; Crash Course General Medicine, 4e includes a lot of information, cases/questions to work through and so may be better but if you are looking for these then why not get the bundle Medicine at a Glance Text and Cases Bundle & if you are a visual learner then the at a Glance title certainly has far more diagrams available.
