Despite the fact that significant contributions to the discipline of
spinal surgery have derived from the Harvard system, no prior study documents the history of the Harvard spine services in a cohesive narrative.
Methods. This historical perspective GSK3326595 cell line reviews the history of adult spine surgery within the Harvard system and outlines the significant contributions made by orthopedic and neurosurgical practitioners to the field. Literature reviews were performed from historical works, as well as scientific publications to fashion a cohesive review covering the history of spine surgery at Harvard from the early 19th century to the present.
Results. The development of the spine surgical services at the three main Harvard hospitals, and significant spine surgical personalities within the system, are discussed, including W. Jason Mixter, MD, Joseph S. Barr Sr., MD, and Marius N. Smith-Petersen, MD. Substantial developments that have arisen from the Harvard teaching hospitals include the recognition of disc herniation as the cause of radicular
symptoms in the lower extremities, the description of lumbar discectomy as a surgical treatment for radicular pain, osteotomy for the correction of spinal deformity, and the first attempt to create a systematic algorithm capable of informing treatment for cervical spine trauma.
Conclusion. Despite humble beginnings, the surgeons click here and scientists at Harvard have influenced nearly every facet of spine surgery over the course of RG-7388 research buy the last two centuries.”
“Peutz-Jeghers syndrome (PJS) is a rare, autosomal dominant inherited disease. It is clinically characterized by the development of gastrointestinal hamartomas, mainly located in the small bowel. These hamartomas are prone to complications such as intussus-ceptions, abdominal complaints and anaemia.
Furthermore, patients are at increased risk for developing small bowel cancer. Therefore, regular surveillance of the small bowel is indicated. However, the optimal strategy for surveillance has not been determined yet. This review gives an overview of the different techniques that have been described to examine the small bowel of PJS patients. First, a number of radiologic and endoscopic imaging modalities with diagnostic value are discussed. Secondly, recently developed advanced endoscopy techniques are described that can serve both as a diagnostic and therapeutic tool in the surveillance of the small bowel. Finally, a recommendation is given how to apply these individual techniques for small bowel surveillance in a step-up approach. (C) 2012 Elsevier Ltd. All rights reserved.
