This comparative-effectiveness study provides evidence for major practice variation in surgical management of severe TBI. Although ages differed between the 2 cohorts, the results suggest that a more aggressive approach, including earlier surgery, larger craniotomy, and removal of bone flap, may reduce ICP, prevent cortical spreading depolarizations, and improve outcomes. In particular, patients requiring evacuation of subdural hematomas and contusions may benefit from decompressive craniectomy in conjunction with lesion evacuation, even when elevated ICP is not a factor in the decision to perform surgery.
OBJECTIVENeurosurgical services are increasingly recognized as essential components of surgical care worldwide. The degree of interest among neurosurgeons regarding international work, and the barriers to involvement in global neurosurgical outreach, are largely unexplored. The authors distributed a survey to members of the American Association of Neurological Surgeons/Congress of Neurological Surgeons (AANS/CNS) Joint Section on Pediatric Neurosurgery to assess the state of global outreach among its members and to identify barriers to involvement.METHODSAn internet-based questionnaire was developed by the International Education Subcommittee of the AANS/CNS Joint Section on Pediatric Neurosurgery and distributed to pediatric neurosurgeons via the AANS/CNS Joint Section email contact list. Participants were surveyed on their involvement in global neurosurgical outreach, geographic location, nature of the participation, and barriers to further involvement.RESULTSA 35.3% response rate was obtained, with 116 respondents completing the survey. Sixty-one percent have performed or taught neurosurgery in a developing country, and 49% travel at least annually. Africa was the most common region (54%), followed by South America (30%), through 29 separate organizing entities. Hydrocephalus was the most commonly treated condition (88%), followed by spinal dysraphism (74%), and tumor (68%). Most respondents obtained follow-up through communications from local surgeons (77%). Seventy-one percent believed the international experience improved their practice, and 74% were very or extremely interested in working elsewhere. Interference with current practice (61%), cost (44%), and difficulty identifying international partners (43%) were the most commonly cited barriers to participation.CONCLUSIONSAny coordinated effort to expand global neurosurgical capacity begins with appreciation for the current state of outreach efforts. Increasing participation in global outreach will require addressing both real and perceived barriers to involvement. Creation and curation of a centralized online database of ongoing projects to facilitate coordination and involvement may be beneficial.
Geniculate neuralgia or nervus intermedius (NI) neuralgia is a rare condition characterized by intermittent, severe, stabbing deep ear pain. The pain can be triggered by stimulation of the external ear and is sometimes accompanied by facial pain. The condition is thought to result, in part, from vascular compression of the NI, although other etiologies exist. To date, fewer than 150 cases have been described in the English-language literature, and only 1 case of surgically treated geniculate neuralgia with microvascular decompression (MVD) of cranial nerves VIII, IX, and X has been described in a pediatric patient. Here, the authors present the case of an adolescent boy with bilateral geniculate neuralgia treated at two different time points with sectioning of the NI and MVD.
OBJECTGanglioglioma (GG) is commonly recognized as a low-grade tumor located in the temporal lobe, often presenting with seizures. Most are amenable to complete resection and are associated with excellent oncological outcome. The authors encountered several GGs in various locations, which seem to have a less favorable clinical course than GGs in the temporal lobe.METHODSThe authors performed a single-center retrospective review of all children with a histological diagnosis of GG who were treated at Children’s Hospital Colorado between 1997 and 2013. Each tumor was categorized by 2 pediatric neuroradiologists as typical or atypical based on preoperative MRI appearance. Typical lesions were cortically based, within a single cerebral lobe, well-circumscribed, and solid or mixed solid/cystic. The treatment and clinical course of each patient was analyzed.RESULTSThirty-seven children were identified, with a median age at presentation of 8.2 years and median follow-up of 38.0 months. Eighteen tumors (48.6%) were typical and 19 (51.4%) were atypical. All typical lesions presented with seizures, whereas no atypical lesions did so. Sixteen (88.9%) typical lesions were located in the temporal lobe. In the atypical group, tumor location was variable, including 11 (57.9%) in the brainstem. Death during follow-up was statistically more common in the atypical group (31.6% vs 0%, p = 0.02). Gross-total resection (GTR) was achieved for 15 of 16 typical tumors (93.8%), compared with 3 atypical tumors (15.8%, p < 0.0001). Presentation with seizure or non-brainstem location were each associated with survival (p = 0.02 and 0.004, respectively). The presence of mutation in BRAF exon 15 did not differ between the 2 groups.CONCLUSIONSPediatric GG with typical imaging features is associated with excellent rates of GTR and overall survival. Atypical GG is commonly encountered, less amenable to GTR, and associated with a worse outcome. This may relate to anatomical or biological characteristics and merits further investigation.
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.
