A survey of the members of the American Society of Pediatric Neurosurgeons and factors associated with well-being.

OBJECTIVE: The goal of this study was to survey the members of the American Society of Pediatric Neurosurgeons (ASPN) to assess the prevalence and associated risks of burnout among pediatric neurosurgeons. The authors aimed to identify the factors that most significantly contributed to this risk to provide a baseline group of characteristics to improve physician well-being. METHODS: Institutional Review Board approval from the University of Arizona was obtained, and the 7-question and 9-question Mayo Physician Well-Being Index (WBI) was distributed to members of the ASPN (n = 275). This index screens for many different aspects of distress for physicians, including burnout risk, stress, depression, fatigue, suicidal ideation, and low career satisfaction. RESULTS: An analysis of 111 pediatric neurosurgeons (111/275 [40% response rate]) was completed. Respondent ages were distributed, with those aged 56-60 years representing the highest proportion (20%). University practice represented a majority (72%). One-third (32%) of respondents reported practicing greater than 25 years, and most physicians in the survey were married (76%). One-third of surgeons spend 61-70 hours working per week (33%), and a plurality are on call between 6 and 10 days per month (42%). Most surgeons reported treating fewer than 200 cases per year (37% reported 100-150 cases; 23%, 151-200). Most pediatric neurosurgeons (63%) stated their annual salary was sufficient. Analysis of each WBI question was performed to identify which factors specifically contributed to the risk of burnout. An overwhelming majority of respondents reported that they make significant efforts to do at least one thing each week that brings them joy (97%), and they either agree or strongly agree that they perform meaningful work (98% of all participants, 97% of females, and 98% of men, p = 0.010). Nearly half of all respondents (49%) reported feelings of burnout and a majority of them were female (67% of women and 42% of men, p = 0.021). Time, environment, case volumes, and quality-of-life concerns are all factors that significantly contribute to the overall risk of burnout and well-being. CONCLUSIONS: This survey study of the ASPN membership revealed a 49% rate of burnout with females at higher risk (67%). Factors associated with burnout were salary, more than 10 days on call per month, electronic medical record stressors, and work-life incongruity. The aforementioned notwithstanding, respondents believe pediatric neurosurgery is a meaningful career. This study provides evidence supporting a moral imperative toward recognition of burnout symptoms and a pivot point toward implementing change.

Missed radiographic and clinical findings in a case of non-idiopathic scoliosis resulting from chondroblastoma.

PURPOSE: Chondroblastoma is a cartilaginous neoplasm which rarely presents in the spine, where it has been shown to exhibit aggressive behavior. We present a case of a late diagnosis of a T12 chondroblastoma causing paraparesis in an 11-year-old girl. Several missed classical radiographic and clinical features are highlighted. METHODS: We reviewed clinical, imaging, and pathology data from the time of transfer to our institution, followed by review of all outside clinical records and imaging data from 14 months prior to admission until onset of paraplegia. RESULTS: The patient was transferred to our center for emergent treatment of a large, expansile, exophytic lesion compressing the spinal cord at T12. Intravenous steroids improved her neurologic status to ASIA Grade B, and an en bloc posterior element resection was performed emergently within 24 h. She rapidly improved to an ASIA Grade E. After obtaining all prior imaging during detailed histopathologic work-up, the final diagnosis was that of spinal chondroblastoma. Subsequent anterior en bloc resection was performed. The patient remains disease-free with a stable, residual scoliosis 7 years postoperatively. CONCLUSIONS: Detailed review of radiographs is essential for scoliosis patients. Earlier recognition of the "winking owl" sign, a kyphotic sagittal alignment, and more concern about a child with a painful curve may have resulted in earlier diagnosis before the onset of neurologic deficits.

Bandages, dressings, and cranial neurosurgery.

OBJECT: Bandages and dressings are commonly applied to incisional scalp wounds to prevent complications, particularly infection, during the early stages of wound healing. Bandaging cranial incisional wounds requires resources, consumes healthcare workers' time, and incurs expense; it is therefore important to examine its efficacy. METHODS: All cranial operations (excluding shunt placements, procedures on the scalp alone, and bur hole procedures) performed between June 30, 2001 and January 1, 2006, by two neurosurgeons at either of two hospitals, one adult and one pediatric institution, were reviewed. Surgical site infections (SSIs) and other postoperative complications were investigated with respect to the use of bandaging for incisional wounds and other aspects of postoperative wound management. The operations were classified into four categories based on wound type: "clean," "clean-contaminated," "contaminated," and "dirty," according to the criteria of the Centers for Disease Control and Prevention. CONCLUSIONS: A total of 702 operations were performed in 577 patients; only five patients received any type of surgical bandaging. There were four SSIs (0.57%; 95% confidence interval [CI] 0.16-1.45). The postoperative infection rate in the 626 clean cases was 0.48% (95% CI 0.10-1.39) and was 2.63% (95% CI 0.07-13.81) in the 38 clean-contaminated cases. The data obtained in this investigation is consistent with the position that bandaging incisional scalp wounds after cranial surgery adds little if any benefit beyond the easier, simpler, and cheaper practice of using antibiotic ointment as a dressing without bandaging.

Vancomycin disposition and penetration into ventricular fluid of the central nervous system following intravenous therapy in patients with cerebrospinal devices.

OBJECTIVE/AIMS: To determine the cerebrospinal fluid concentrations and percent CNS penetration of intravenous vancomycin in patients with cerebrospinal devices at a pediatric institution. METHODS: We performed a prospective evaluation of intravenous (IV) vancomycin in patients who received a single prophylactic dose of vancomycin (15-20 mg/, maximum dose 1 g) prior to insertion of a CNS shunt (group I) or a therapeutic regimen (a dose of 10-20 mg/kg every 6-12 h) for a documented/suspected shunt infection (group II). Ventricular cerebrospinal fluid (VCSF) samples were taken during the procedure in group I and multiple serum and VCSF samples were collected in group II. Pharmacokinetic parameters were calculated using a one-compartment model, and percent CNS penetration was estimated using area-under-the-curve methodology. RESULTS: Group I: 21 VCSF samples were analyzed from 19 patients (mean age 7.2 +/- 6.4 years). Over 40% of samples failed to have detectable vancomycin concentrations (range 0-2 microg/ml). Group II: 6 patients (mean age 11 +/- 8.7 years) had VCSF concentrations ranging from nondetectable to 6.59 microg/ml (mean 2.48 +/- 0.52 microg/ml). Percent penetration ranged from 0.77 to 18%. CONCLUSIONS: Single-dose, pre-operative vancomycin results in low VCSF vancomycin concentrations and repeated dosing in patients with documented/presumed device infections yields variable CNS penetration.

Cerebrospinal fluid shunt operations without cranial bandaging. Clinical article.

OBJECT: Cranial bandages are commonly applied over scalp incisions immediately after cerebrospinal fluid (CSF) shunt surgery, putatively to prevent complications, particularly infection. These bandages require resources, consume the time of healthcare workers, and incur non-negligible expenses. It is therefore both reasonable and important to examine the efficacy of cranial bandaging. METHODS: The combined experience of 3 neurosurgeons over 6.75 years with using no cranial bandaging after operations for implantation or revision of CSF shunts is the basis of this report. These data were prospectively accrued and retrospectively analyzed. RESULTS: The infection rate was 4.2% (95% CI 3.1-5.6%) for 1064 operations performed without postoperative cranial bandaging after either shunt insertion or revision surgery through clean or clean-contaminated wounds. The age distribution extended from premature infants through adults 77 years of age. CONCLUSIONS: The results of this investigation support the position that bandaging scalp wounds after CSF shunt implantation or revision surgery adds no benefit beyond the easier, simpler, faster, and cheaper practice of using antibiotic ointment as a dressing without bandaging.

Cystoventricular shunting of intracranial arachnoid cysts.

Ten patients with intracranial arachnoid cysts were treated with direct shunting of the cyst to a lateral ventricle. The strategic goal of cystoventricular shunting is to establish physiologically normal intracranial pressure relationships, rather than cyst obliteration. Cystoventricular shunts were successful in treating single and multiple intracranial cysts in supratentorial and infratentorial locations and in patients with normal and enlarged lateral ventricles. Cystoventricular shunting is conceptually simple as well as effective and reliable.

Variability in brain death declaration practices in pediatric head trauma patients.

The American Academy of Pediatrics' 'Guidelines for the determination of brain death in children' [Pediatrics 1987;80: 298-300] has been cited since its publication as the definitive reference for all cases of pediatric brain death. As these guidelines appear to have been designed for use in patients where the etiology of coma is unclear, they often seem inappropriate in cases of severe head trauma. We questioned whether these guidelines were truly the national standard of practice, particularly in instances of brain death secondary to head trauma. We conducted a survey of pediatric hospitals and pediatric neurosurgeons across the country regarding this matter, and found that their brain death declaration practices varied widely. The majority of hospitals and neurosurgeons in our survey do not follow the guidelines exactly. We feel that these guidelines should be reevaluated and perhaps revised, especially in the setting of severe head trauma.
