This book covers interesting and yet often challenging cases among adult patients in a unique Question-Answer format. Simulating the bed-side case discussions during the ward rounds, one question logically leads to another question thereby generating curiosity and promoting evidence-based medicine. Taking the readers through the entire spectrum starting from etiology and pathophysiology to clinical presentation to management principles, each question addresses one key aspect of the disorder. Described in a very simple and lucid narrative, this book ensures sound conceptual understanding while covering each topic comprehensively. This volume covers important topics such as acromegaly, Cushing syndrome, osteoporosis, hypercalcemia, pheochromocytoma, hyperaldosteronism, thyroid disorders and diabetes in adult patients. These cases are not only seen by endocrinologists, but are also managed by internists, orthopedic surgeons, obstetricians and gynecologists. Less common disorders such as adrenal disorders and androgen excess have also been covered.
