Cervical spine surgery in the ancient and medieval worlds.
The early historical literature on cervical spine surgery lacks printed material for review, and we can rely only on pathological material from the prehistoric period that has survived as a result of anthropological investigations. After the introduction of Egyptian and early Hellenic medicine, some written material became available. This paper reviews these materials, from both books and manuscripts, in an effort to understand the development of cervical spine surgery from the perspectives of the personalities involved and the early surgical practices used. The review thus considers the following five eras of medicine: 1) prehistoric; 2) Egyptian and Babylonian; 3) Greek and early Byzantine; 4) Middle Eastern; and 5) medieval.

Hippocrates' influence on the origins of neurosurgery.
Hippocrates is widely considered the father of medicine. His contributions revolutionized the practice of medicine and laid the foundation for modern-day neurosurgery. He inspired several generations to follow his vision, by pioneering the rigorous clinical evaluation of cranial and spinal disorders and combining this approach with a humanistic and ethical perspective focused on the individuality of the patient. His legacy has forever shaped the field of medicine and his cumulative works on head injuries and spinal deformities led to the basic understanding of many of the fundamental neurosurgical principles in use today.

Decision making in head injury management in the Edwin Smith Papyrus.
The Edwin Smith Papyrus (circa 1650-1550 BC) is a didactic trauma treatise of major interest to neurosurgery, as it deals primarily with cranial and spine injuries. Information regarding the patient's condition is conveyed in the papyrus with sufficient clarity to allow a clinical assessment of each injury. ⋯ Factors identified as determinant for the third verdict in head injuries are depressed skull fragments, dura laceration with exposed brain, infected cranial wounds/tetanus, major craniofacial fractures, deep skull-penetrating stab wounds, and aphasia. This study describes three case sequences of head injuries.

The management of cranial injuries in antiquity and beyond.
Cranial injuries were among the earliest neurosurgical problems faced by ancient physicians and surgeons. In this review, the authors trace the development of neurosurgical theory and practice for the treatment of cranial injuries beginning from the earliest ancient evidence available to the collapse of the Greco-Roman civilizations. The earliest neurosurgical procedure was trephination, which modern scientists believe was used to treat skull fractures in some civilizations. ⋯ Finally, Galen of Pergamon, a physician to fallen gladiators, substantially contributed to the understanding of the neuroanatomy and physiology. He also described his own classification system for skull fractures and further refined the surgical technique of trephination. From the study of these important ancient figures, it is clearly evident that the knowledge and experience gained from the management of cranial injuries has laid the foundation not only for how these injuries are managed today, but also for the development of the field of neurosurgery.

Meningiomas are slow growing, extraaxial tumors that derive from the arachnoidal cap cells of the meninges. Resection remains the main modality of treatment and can be curative in some cases. External-beam radiotherapy and radiosurgery can benefit selected patients. ⋯ Results of preliminary clinical studies suggest that hydroxyurea has modest activity against recurrent and inoperable meningiomas, and can induce long term stabilization in some patients. However, the results are conflicting and a few clinical trials did not show positive results. Further clinical trials with larger patient cohorts and longer follow-up periods will be necessary to confirm the activity of hydroxyurea.
