The book "Ankylosing Spondylitis" by J. Forestier, F. Jacqueline, and J. Rotes-Querol, published in 1956, emphasizes the distinct clinical entities of ankylosing spondylitis and rheumatoid arthritis. The authors detail early symptoms such as sacroiliac syndrome and highlight the importance of a thorough clinical examination. They note that peripheral joint involvement often precedes spinal symptoms. The book discusses diagnostic challenges, including the lack of mention of crippling fluorosis and sacroiliac joint changes in traumatic paraplegia. It provides insights into laboratory tests and x-ray appearances, though it could have included more information on synovial fluid examination. The authors describe rare cases where early bony condensation near the sacroiliac joints resolves without progression to ankylosis. The treatment regimen, including rest, exercise, and the use of gold, is discussed, along with the limitations of radiotherapy and the value of cortisone and ACTH therapy for severe cases. Overall, the book offers a detailed and valuable account of ankylosing spondylitis. "Rhumatologie Clinique" by Pierre P. Ravault and Georges Vignon, published in 1956, serves as a practical guide to rheumatology, covering major diseases like osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. It includes excellent chapters on these conditions and a detailed section on scapulo-humeral periarthritis. The book is praised for its clear format, high-quality x-ray photographs, and detailed interpretations. However, it falls short in treating minor affections, such as the menopausal syndrome affecting the median nerve and trigger finger, which are not adequately addressed.The book "Ankylosing Spondylitis" by J.
