It is estimated that the functionally significant body of knowledge for a given medical specialty changes radically every 8 years. New specialties and "sub-specialization" are occurring at approximately an equal rate. Historically, established journals have not been able either to absorb this increase in publishable material or to extend their readership to the new specialists. International and national meetings, symposia and seminars, workshops, and newsletters suc cessfully bring to the attention of physicians within developing spe cialties what is occurring, but generally only in demonstration form without providing historical perspective, pathoanatomical corre lates, or extensive discussion. Page and time limitations oblige the authors to present only the essence of their material. Pediatric neurosurgery is an example of a specialty that has de veloped during the past 15 years. Over this period neurosurgeons have obtained special training in pediatric neurosurgery and then dedicated themselves primarily to its practice. Centers, Chairs, and educational programs have been established as groups of neuro in different countries throughout the world organized surgeons themselves respectively into national and international societies for pediatric neurosurgery. These events were both preceded and fol lowed by specialized courses, national and international journals, and ever-increasing clinical and investigative studies into all aspects of surgically treatable diseases of the child's nervous system.

I have a dog. An inconvenient dog. When I wake up, my dog is inconvenient. When I'm getting dressed, my dog is inconvenient. And when I'm making tunnels, my dog is SUPER inconvenient. But sometimes, an inconvenient dog can be big and warm and cuddly. Sometimes, an inconvenient dog can be the most comforting friend in the whole wide world.
