The advent of the microscope in the operating room revolutionized neurosurgery. We traced the origin and evolution of this important invention from the first magnifying lens to its practical application in neurosurgery. The concept of magnification evolved from unexplained observations in ancient times to the invention of the microscope by the late 16th century. In the subsequent 3 centuries, scientists made technical advances that greatly improved the power and utility of the microscope. By the early 20th century, otolaryngologists became the first surgeons to use the microscope in clinical surgery. After World War II, ophthalmologists and vascular and plastic surgeons began using the microscope in the operating room, making further technical improvements. It was a relatively small group of pioneering neurosurgeons in the late 1950s and 1960s who transformed microneurosurgery from a revolutionary and unorthodox "experiment" into the standard of care in much of modern neurosurgery.
Infectious mononucleosis (IM) is a common medical condition that afflicts thousands of young athletes each year. Despite the self-limited nature of this disorder, the variability of the clinical presentation and the rare risk of splenic rupture routinely present sports medicine clinicians with difficult return-to-play decisions. Currently there are no evidence-based guidelines regarding the management of the athlete with IM. This review discusses the available research data pertaining to the management of IM in young athletes and develops questions for future clinical research.
Inflammatory myofibroblastic tumor (IMT) is a tumor composed of myofibroblasts and a mixed inflammatory infiltrate that rarely undergoes malignant transformation. The authors present the case of a 7-year-old boy with an abdominal mass diagnosed as IMT with malignant transformation. The tumor recurred twice after attempts at resection and was initially treated with vincristine and etoposide. After a third recurrence and incomplete resection, he was treated with cisplatin, Adriamycin, and methotrexate. He is disease-free after 2 years, representing successful combined surgery and chemotherapy in the treatment of malignant IMT. The use of chemotherapy for aggressive myofibroblastic tumors is reviewed.
OBJECTIVE. In thisstudy, we evaluated theincidence of dorsal cutaneous stigmata in a healthy neonate population; we also assessed whether specific types of cutaneous stigmata are associated with underlying spinal dysraphism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
