Cytological techniques have greatly improved in the last twenty years, largely as a result of further development of the microscope. Electron microscopy, in particular, has opened up great prospects for the study of cell morphology, while the develop- ment of radio-immuno-assay has brought great progress in endocrinology. The applica- tion of these two techniques, which are complementary to each other and provide mutually supporting evidence, is the subject of this monograph. The work is divided into two parts. The first deals with the ultrastructure of normal testicular development,...

Ferment, a sign of progress in any scientific field, has previously been lacking in the area of cryptorchidism, where the only activity has been in improving operative methods. Now, however, profound changes in the care of boys with cryptorchidism are being brought about; ideas are arising from a fresh look at comparative anatomy, and histological and experimental observa tions are being supplemented by clinical tests made possible by new hormonal agents. The treatment of cryptorchidism begins with its recognition by the pediatri cian, who until now has shown little interest because of...

Despite significant progress in modern gastroenterology, the aetiology of inflammatory bowel disease as well as coeliac disease is still to a great extent unknown and poorly understood. The principles of treatment - particularly of IBD - emphasize the importance of a combined medical and surgical approach. This book is the proceedings of an international symposium that brought together workers from many disciplines involved in the treatment of IBD and coeliac disease, and is a useful update on recent advances in paediatric and paediatric-surgical gastroenterology.
