Online access to the Oxford Textbook of Medicine in low and middle income countries is available through the World Health Organization-led HINARI Access to Research in Health programme. 

Latest update

The November 2012 update sees updates to over 70 chapters, focusing on Neurology and Gastroenterology. This update also incorporates a selection of 29 Case Histories taken from related titles in the Oxford Case Histories series, linked to from related chapters. Each case includes several questions followed by detailed answers and discussion to enhance diagnostic and clinical understanding.

Neurology updates include substantial updates to key chapters and new material on a wide range of topics including spinal cord injury, autonomic nervous system disorders, and inherited neurodegenerative diseases. 

Gastroenterology updates include extensive revisions of key chapters on liver failure and acute pancreatitis and new material on a wide range of matters, ranging from the common to the rare: including surgical treatments for colonic diverticular disease, antibody tests for immune disorders, and a revised treatment algorithm for small bowel bacterial overgrowth.

This section outlines the general principles of intracellular signalling. Focusing on cell surface receptors, the requirements for effective transmission of information across the plasma membrane are outlined. The principal mechanisms utilized in mammalian signal transduction are described. For each, the pathological consequences of aberrant signalling and means by which pathways can be pharmacologically targeted are described in molecular terms.

Intracellular signalling pathways permit the transmission and integration of information within cells. Mammalian receptor signalling relies on only a small number of distinct molecular processes which interact to determine cellular responses. Rapid advances in our knowledge of the mechanisms of intracellular signalling has greatly increased understanding of how cells function physiologically, how they malfunction pathologically and how their behaviour might be manipulated therapeutically.
