Distinguished clinician-scientists describe in concise studies their most difficult cases and reveal what they did, how they did it, and why. The cases cover a wide range of endocrine problems. Each case study reviews how the patient was managed, details the reasons why various tests and treatments-many only recently available-were carried out, and provides references to ensure that those novel methodologies can be easily translated into the endocrine specialist's daily practice. The authors provide practical solutions for these difficult-to-manage cases, and successfully apply knowledge fresh from the laboratory to decisions about patient management. Practical and stimulating, Challenging Cases in Endocrinology demonstrates for every clinical endocrinologist precisely how specialists approach their most challenging cases and how these approaches can be effectively applied in the daily practice of endocrinology.
