Use of Direct Intracranial Pressure and Brain Tissue Oxygen Monitoring in Perioperative Management of Patients with Moyamoya Disease.

Intracranial pressure monitoring and brain tissue oxygen monitoring are commonly used in head injury for goal-directed therapies, but there may be more indications for its use. Moyamoya disease involves progressive stenosis of the arterial circulation and formation of collateral vessels that are at risk of hemorrhage. The risk of ischemic events during revascularization surgery and postoperatively is high. Impaired cerebral autoregulation may be one of the factors that are implicated. We present our experience with monitoring of cerebral oxygenation and autoregulation in the pathological hemisphere during the perioperative period in four patients with moyamoya disease.

Traumatic atlanto-occipital dislocation in children: is external immobilization an option?

OBJECT: Traumatic atlanto-occipital dislocation (AOD) is a relatively uncommon traumatic cervical spine injury characterized by disruption and instability of the atlanto-occipital joint. At many centers, management of pediatric AOD includes occipitocervical arthrodesis, but whether external immobilization without surgery is a viable treatment option for some pediatric patients is unknown. To answer this question, we analyzed our outcomes of pediatric AOD at the Hospital for Sick Children. METHODS: We performed a retrospective chart review of all children with clinical and radiographic evidence of traumatic AOD. A total of 10 patients met criteria for traumatic AOD: 8 were treated with external immobilization alone and 2 were treated with occipitocervical arthrodesis. RESULTS: Eight patients were treated exclusively with 3 months of halo immobilization. Two patients were treated with occipitocervical instrumentation and arthrodesis. No patient undergoing halo immobilization required subsequent operative fusion. CONCLUSION: Halo immobilization is a safe, viable, and definitive treatment option for the selected children with AOD.

The role of social media in selective dorsal rhizotomy for children: information sharing and social support.

PURPOSE: Selective dorsal rhizotomy (SDR) is a surgical treatment for spasticity, primarily in cerebral palsy (CP). There is a growing trend for patients to seek medical information from their peers on social media platforms. This study qualitatively and quantitatively assessed the use of social media as an information-sharing and support-seeking tool by patients and caregivers. METHODS: A search was performed on Facebook, Twitter, and YouTube. Public information was quantitatively assessed by category, users, year of creation, and country of origin. Representative samples of comments and posts were then qualitatively assessed by thematic analysis. RESULTS: One hundred eighty-five Facebook groups and pages, 97 YouTube videos, and 14 Twitter accounts were identified, based in 13 countries. SDR and CP groups had a mean membership of 3063 and 2339, respectively; SDR and CP pages had a mean number of "likes" of 1650 and 10,711, respectively. Total YouTube video views were 593,135 (mean 6115). Total Twitter followers were 62,609 (mean 2160). Qualitative analysis identified seven categories of comments: emotional support and forming connections (22.34%), sharing information and advice (15.96%), appreciation and successes (31.91%), challenges and difficulties (8.51%), advertising/offering services (4.79%), inequities and access (4.79%), and social media as a second opinion (11.7%). CONCLUSIONS: This study outlines the use of social media platforms in the distribution of information regarding SDR. We highlight the importance placed by patients and caregivers on the advice of their peers. The current report should inform healthcare providers' interactions with patients with respect to information seeking and provision of support.
