Fibrin sealant augmentation with autologous pericranium for duraplasty after suboccipital decompression in Chiari 1 patients: A case series.

BACKGROUND: The Chiari 1 malformation (CM1) involves decent of the tonsils of the cerebellum through the foramen magnum. Symptomatic disease requires a posterior fossa decompression with or without an expansile duraplasty. To date, the optimal surgical treatment for CM1 has not been delineated. The extent of bony removal, size of the dural opening, necessity for expansion of the dural space, choice of materials for the duraplasty, and possible need for augmentation with dural sealant are all factors that continue to be debated amongst neurological surgeons worldwide. We herein evaluate the use of fibrin sealant augmentation in combination with locally harvested autologous pericranium for duraplasty in adult CM1 decompression. METHODS: Retrospective data collected from January 2006 to December 2011. Data were reviewed for surgical site infection or meningitis, cerebrospinal fluid leak, symptomatic pseudomeningocele, radiographic improvement of hindbrain compression, and postoperative recurrence of symptoms at a minimum of 1 year of follow-up. Outcomes were studied clinically, radiographically, as well as by using a patient-specific questionnaire. RESULTS: Twenty-two consecutive patients were included. One patient required a revision for a delayed graft dehiscence in the setting of a rare form of aseptic meningitis with cerebrospinal fluid (CSF) pleocytosis due to a nonsteroidal anti-inflammatory drug (NSAID) allergy. All remaining patients had successful decompressions with full resolution of their symptoms except for one patient who had persistent headaches. CONCLUSION: Autologous pericranium with dural sealant augmentation is an effective technique for expansile duraplasty in CM1 decompressions.

Quo vadis, academia? Can academic neurosurgery be resurrected?

Clinical neurosurgery is an endangered academic discipline. Neurosurgeons have competition from many directions: orthopedists, ear, nose and throat surgeons, plastic surgeons, radio-oncologists, and interventional radiologists, among others. Academic centers are no longer the only sites of neurosurgical education at the attending level, and neurosurgery is not felt to be an indispensible part of an undergraduate medical curriculum. There are insufficient data to determine if neurosurgical services for the general population are adequate or appropriate. The traditional strengths of academic neurosurgery are gathering data, analysis, research, innovation, and teaching within a context of understanding and tradition. Future healthy development of neurosurgery ideally requires multidisciplinary teams in specialized referral centers. When this consideration is combined with the existing shortage of neurosurgeons across the country, academic neurosurgery departments must logically focus on how best to allocate resources between "routine" clinical services and research objectives. We suggest here that new relationships may be required between university centers and community health care providers. Restructuring of the neurosurgical workforce may be necessary if academic neurosurgery is to develop as a specialty of comprehensive expertise in the challenging neurological disease entities that are its research objectives.

Injury and illness at the Newport-Bermuda race 1998- 2006.

OBJECTIVE: To describe the relative frequency and types of injury and illness in the Newport-Bermuda off-shore yachting race. METHODS: At the end of each race held in even numbered years from 1998-2006, the captain of each boat was asked to complete a survey detailing any injury or illness among his/her crew. RESULTS: There was an overall 87% response rate to the survey. During the study period, 38 injuries and 57 illnesses were reported for an estimated 8105 sailors, yielding rate of injury or illness of 12 per 1000 races per sailor. Most common were injuries to the upper extremity (47%), and lacerations were the most common type of injury (45%). Sea sickness was the most common illness, and the rate of illness and injury increased in races that took place in heavy weather. Radio consultations were used 4 times, and 3 sailors required transport to a hospital. CONCLUSIONS: The rate of injury and illness was relatively low in the Newport-Bermuda race. Injuries to the upper extremities and lacerations were most common, and sea sickness was the most common illness. The majority of illness and injury can be initially managed onboard.
