A Cohort Study of the Natural History of Odontoid Pseudoarthrosis Managed Nonoperatively in Elderly Patients.

OBJECTIVE: Although the primary goal of treatment of type II odontoid fracture is bony union, some advocate continued nonsurgical management of minimally symptomatic older patients who have fibrous union or minimal fracture motion. The risk of this strategy is unknown. We reviewed our long-term outcomes after dens nonunion to define the natural history of Type II odontoid fractures in elderly patients managed nonoperatively. METHODS: A retrospective chart review of 50 consecutive adults aged 65 or older with Type II odontoid fracture initially managed nonsurgically from 1998 to 2012 at a single tertiary care institution was conducted. Particular attention was paid to patients who had orthosis removal despite absent bony fusion. Patients were contacted prospectively by telephone and followed until death, surgical intervention, or last known contact. RESULTS: Fifty patients initially were managed nonsurgically; of these, 21 (42.0%) proceeded to bony fusion, 3 (6%) underwent delayed surgery for persistent instability, and 26 (52%) had orthosis removal despite the lack of solid arthrodesis on imaging. The last group had a median follow-up of 25 months (range 4-158 months), with 20 of 26 (76.9%) followed until death. Of these patients, 1 patient developed progressive quadriplegia and dysphagia 11 months after initial injury. Compared with patients with spontaneous union, patients with nonunion had shorter life expectancy, despite no significant differences between the groups with respect to age, sex, injury mechanism, radiographic variables, or follow-up duration. CONCLUSIONS: Orthosis removal despite fracture nonunion may be reasonable in elderly patients with Type II dens fractures.

Parental satisfaction with being present in the operating room during the induction of anesthesia prior to pediatric neurosurgical intervention: a qualitative analysis.

OBJECTIVE Parental presence in the operating room during the induction of anesthesia (PPIA) has been shown to decrease parent and child anxiety and increase satisfaction with patient experience in outpatient otolaryngological procedures, such as tympanostomy tube placement. PPIA for other procedures, such as a major neurosurgical intervention, has been a practice at the authors' institutions for many years. This practice is not universally accepted across the United States, and the potential benefits for patients and families have not been formally evaluated. The aim of this study is to provide a qualitative analysis of parental and patient satisfaction with PPIA at the authors' institution. METHODS All patients younger than 18 years who underwent surgical intervention at the authors' institution between August 2013 and December 2015 were identified. All surgeries were performed by a single neurosurgeon. A random sample of 96 parents were contacted by telephone for a qualitative, semiscripted interview; 42 parents completed the interviews. The interview consisted of a validated satisfaction assessment in addition to a standardized open-ended questionnaire. Thematic analysis was performed until saturation was achieved, and responses were coded into the predominant themes. Member checking was performed, and a thick description was created. RESULTS The predominant themes identified with PPIA were 1) perception of induction as traumatizing or distressing to witness, 2) positive feelings regarding having been present, 3) satisfaction regarding the overall experience with surgery, 4) variable feelings in parents who decided not to attend induction, and 5) mixed feelings in the interactions with the care team. Parents expressed an array of positive, negative, and neutral impressions of the experience; however, overall, most experiences were positive. Most parents would choose PPIA again if their child required additional surgery. CONCLUSIONS This is the first study to evaluate the benefit of PPIA for pediatric neurosurgical patients. The results show a unique insight into medical communication and patient satisfaction with high-risk surgeries. PPIA may be able to help shape an environment of trust and increase satisfaction with perioperative care.

Anti-cytokine autoantibodies are associated with opportunistic infection in patients with thymic neoplasia.

Patients with thymic malignancy have high rates of autoimmunity leading to a variety of autoimmune diseases, most commonly myasthenia gravis caused by anti-acetylcholine receptor autoantibodies. High rates of autoantibodies to cytokines have also been described, although prevalence, spectrum, and functionality of these anti-cytokine autoantibodies are poorly defined. To better understand the presence and function of anti-cytokine autoantibodies, we created a luciferase immunoprecipitation system panel to search for autoantibodies against 39 different cytokines and examined plasma from controls (n = 30) and patients with thymic neoplasia (n = 17). In this screen, our patients showed statistically elevated, but highly heterogeneous immunoreactivity against 16 of the 39 cytokines. Some patients showed autoantibodies to multiple cytokines. Functional testing proved that autoantibodies directed against interferon-α, interferon-ß, interleukin-1α (IL-1α), IL-12p35, IL-12p40, and IL-17A had biologic blocking activity in vitro. All patients with opportunistic infection showed multiple anti-cytokine autoantibodies (range 3-11), suggesting that anti-cytokine autoantibodies may be important in the pathogenesis of opportunistic infections in patients with thymic malignancy.
