Pyrexia: A Clinical Perspective by Dr. Munish Rastogi is a concise yet comprehensive guide that explores fever as a vital clinical symptom and diagnostic clue. The book emphasizes the importance of understanding pyrexia not merely as an elevation in temperature but as a complex physiological response reflecting underlying pathology. Dr. Rastogi systematically explains the mechanisms of fever, including the role of pyrogens, cytokines, and thermoregulatory centers, making the content accessible to students and clinicians alike.
A significant strength of the book is its structured approach to differential diagnosis. It categorizes pyrexia based on duration, pattern, and associated clinical features, helping readers develop a logical framework for evaluating febrile patients. The sections on Pyrexia of Unknown Origin (PUO) are particularly valuable, offering practical algorithms, case-based examples, and current investigative strategies.
Dr. Rastogi also highlights common pitfalls in fever evaluation, rational use of antibiotics, and the importance of clinical judgment over unnecessary investigations. The text integrates recent advances and evidence-based guidelines, making it relevant for modern clinical practice.
Overall, the book serves as an essential reference for medical students, residents, and practicing clinicians, providing clear insights into one of the most common yet diagnostically challenging symptoms encountered in medicine.
