`
`
`
`
`In the second edition of this introductory text,_]. T. R. Clarke
`
`
`
`
`
`
`again masterfully succeeds in summarizing inherited meta-
`
`
`
`
`
`
`
`
`bolic diseases for the non-metabolic specialist. The new
`
`
`
`
`
`
`
`
`
`edition updates the latest research as well as diagnostic and
`
`
`therapeutic tools, while
`expanding the discussion of
`
`
`
`
`
`
`mitochondrial and genetic contributions to disease. Despite
`
`
`
`
`
`
`
`
`
`
`
`the significant expansion of the field in the last six years, A
`
`
`
`
`
`
`
`
`C'lz'm"ml Guide to In/ierited Metabolic Direarer retains its readily
`accessible format, making it suitable for reference in a clinical
`
`
`
`
`
`
`
`
`setting or as a review text.
`
`
`
`
`
`
`
`
`
`
`
`
`
`This book consists of 10 concise chapters and 288 pages,
`
`
`
`
`
`
`
`
`only minimally longer than the first edition. Undoubtedly, for
`
`
`
`
`
`
`
`most clinicians and trainees,
`the patient with a potential
`
`
`
`
`
`
`inborn error of metabolism remains quite intimidating,
`
`
`
`
`
`
`
`
`
`
`a situation not helped by flashbacks to the all-too-quickly-
`
`
`
`
`
`
`
`forgotten principles of biochemistry and physiology. The goal
`
`
`
`
`
`
`
`
`
`
`of the book is to calm those fears by introducing basic
`
`
`
`
`
`concepts within a clinically oriented framework. Clarke
`
`
`
`
`
`
`
`
`succeeds in this goal, distilling a very broad, complex, and
`ever-expanding field into a usable, well-written text that
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`contains extensive clinical examples and a multitude of
`
`
`
`
`
`
`
`
`
`diagrams and tables to facilitate rapid reference. As was the
`
`
`
`
`
`
`
`
`
`first edition, the second edition is a necessity for all trainees
`
`
`
`
`
`
`
`
`and professionals who care forinfants and children, especially
`in inpatient settings.
`
`
`
`
`
`
`
`
`
`An author writing a review is faced with a dilemma:
`
`
`
`
`
`
`
`whether to write a “cookbook” with only algorithms and
`
`
`
`
`
`
`
`
`
`
`tables that can be carried around—-but that might miss the
`
`
`
`
`
`
`
`opportunity to provide basic concepts and thereby enable
`
`
`
`
`
`
`
`long-term understanding of mechanisms-—or to provide
`
`
`
`
`
`
`
`
`
`
`a review of all knowledge in the field in encyclopedic form,
`risking that the text will remain on the shelf, unavailable to
`
`
`
`
`
`
`
`
`
`
`the clinician. Clarke is able to address this dilemma and
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`balance the short—term need for readily available diagnostic
`
`
`
`
`
`
`
`
`and treatment guidelines, yet he provides enough theory and
`
`
`
`
`
`
`explanation to provide a groundwork for understanding the
`mechanisms.
`
`
`
`
`
`
`
`
`
`The second edition begins with an excellent review of
`
`
`
`
`
`basic principles, covering metabolism, genetics (including
`
`
`
`
`
`mitochondrial
`inheritance), and a brief introduction to
`
`
`
`
`
`
`
`diagnosis and diagnostic dilemmas. The next six chapters
`
`
`
`
`
`
`
`are arranged according to clinical presentation, allowing for
`
`
`
`
`
`
`
`
`rapid review of a topic. Each chapter is introduced with
`
`
`
`
`
`
`
`
`
`a concise summary of the physiology of the normal and
`
`
`
`
`
`
`
`disease states, and well-constructed cartoons and simplified
`
`
`
`
`
`
`pathways further facilitate understanding of the underlying
`
`Page 1 of 1
`
`
`
`
`
`
`
`
`
`physiology of the derangement. Clarke does not attempt to
`
`
`
`
`
`
`
`provide a laundry list of diagnoses associated with a de-
`rangement; rather, he presents and discusses several detailed
`
`
`
`
`
`
`
`
`
`
`
`
`
`examples of specific diseases, utilizing extensive clinical
`
`
`
`
`
`
`information provided in tables, charts,
`illustrations, and
`
`
`
`
`
`
`photographs. Each chapter closes with a discussion of
`
`
`
`
`
`
`diagnosis and treatment options. Throughout
`the book,
`
`
`
`
`
`
`chapters have multiple subtitles,
`further enabling rapid
`
`
`
`
`
`
`
`reference, and are followed by a brief bibliography of
`essential references, selected so as not to overwhelm those
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`who desire a more in-depth investigation. The text has
`
`
`
`
`
`
`
`
`
`
`a thorough, easy-to-use index as well as a comprehensive list
`
`
`
`
`
`
`
`
`of Web sites
`for parents and for
`further
`reading or
`investigation.
`
`
`
`
`
`
`
`
`New to this edition is a chapter on newborn screening,
`
`
`
`
`
`
`which includes a discussion of tandem mass spectrometry,
`
`
`
`
`
`
`
`
`
`
`a very timely topic for those who care for neonates and
`
`
`
`
`
`
`
`
`
`children or for those who formulate public policy. The final
`
`
`
`
`
`
`
`
`
`two chapters of the text address diagnosis and treatment in
`
`
`
`
`
`
`
`greater detail, again covering the treatment of specific
`diseases in more detail.
`
`
`
`
`
`
`
`
`
`
`This book is compact, portable, and very reasonably
`
`
`
`
`
`
`
`
`
`priced at 1540. Because it is arranged by clinical presentation
`
`
`
`
`
`
`
`
`rather than specific disease, and contains a myriad of tables,
`
`
`
`
`
`
`cartoons, photographs, and charts, it successfully balances
`
`
`
`
`
`
`
`
`
`the clinical need for expediency and the long-term desire
`
`
`
`
`
`
`
`
`for understanding concepts. The text is an excellent value
`
`
`
`
`
`
`
`
`
`
`and would be most useful to all pediatric and genetic resi
`
`
`
`
`
`
`
`
`
`dency libraries, as well as to any student or professional
`
`
`
`
`
`
`
`
`interested in the diagnosis and care of patients with
`metabolic diseases.
