Delayed Complications

OBJECTIVESkull fractures represent a common source of morbidity in the pediatric trauma population. This study characterizes the type of follow-up that these patients receive and discusses predictive factors for follow-up.METHODSThe authors reviewed cases of nonoperative pediatric skull fractures at a single academic hospital between 2007 and 2017. Clinical patient and radiological fractures were recorded. Recommended neurosurgical follow-up, follow-up appointments, imaging studies, and fracture-related complications were recorded. Statistical analyses were performed to identify predictors for outpatient follow-up and imaging.RESULTSThe study included 414 patients, whose mean age was 5.2 years; 37.2% were female, and the median length of stay was 1 day (IQR 0.9–4 days). During 438 clinic visits and a median follow-up period of 8 weeks (IQR 4–12, range 1–144 weeks), 231 imaging studies were obtained, mostly head CT scans (55%). A total of 283 patients were given recommendations to attend follow-up in the clinic, and 86% were seen. Only 12 complications were detected, including 7 growing skull fractures, 2 traumatic encephaloceles, and 3 cases of hearing loss. Primary care physician (PCP) status and insurance status were associated with a recommendation of follow-up, actual follow-up compliance, and the decision to order outpatient imaging in patients both with and without intracranial hemorrhage. PCP status remained an independent predictor in each of these analyses. Follow-up compliance was not associated with a patient’s distance from home. Among patients without intracranial hemorrhage, a follow-up recommendation and actual follow-up compliance were associated with pneumocephalus and other polytraumatic injuries, and outpatient imaging was associated with a bilateral fracture. No complications were found in patients with linear fractures above the skull base in those without an intracranial hemorrhage.CONCLUSIONSPediatric nonoperative skull fractures drive a large expenditure of clinic and imaging resources to detect a relatively small profile of complications. Understanding the factors underlying the decision for clinic follow-up and additional imaging can decrease future costs, resource utilization, and radiation exposure. Factors related to injury severity and socioeconomic indicators were associated with outpatient imaging, the decision to follow up patients in the clinic, and patients’ subsequent attendance. Socioeconomic status (PCP and insurance) may affect access to appropriate neurosurgical follow-up and deserves future research attention. Patients with no intracranial hemorrhage and with a linear fracture above the skull base do not appear to be at risk for delayed complications and could be candidates for reduced follow-up and imaging.

Abstract Direct oral anticoagulants (DOACs) are increasingly prescribed in treatment of cancer-associated thrombosis, but limited data exist regarding safety of DOACs in patients with brain metastases. We aimed to determine the incidence of intracranial hemorrhage (ICH) in patients with brain metastases receiving DOACs or low-molecular-weight heparin (LMWH) for venous thromboembolism or atrial fibrillation. An international 2-center retrospective cohort study was designed. Follow-up started on the first day of concomitant anticoagulation and brain tumor diagnosis. At least 2 brain imaging studies were mandated. The primary outcome was the cumulative incidence of any spontaneous ICH at 12-month follow-up with death as a competing risk. Major ICH was defined as spontaneous, ≥10 mL in volume, symptomatic, or requiring surgical intervention. Imaging studies were centrally reviewed by a neuroradiologist blinded for anticoagulant type. PANWARDS (platelets, albumin, no congestive heart failure, warfarin, age, race, diastolic blood pressure, stroke) score for prediction of ICH was calculated. We included 96 patients with brain metastases (41 DOAC, 55 LMWH). The 12-month cumulative incidence of major ICH was 5.1% in DOAC-treated patients and 11.1% in those treated with LMWH (hazard ratio [HR], 0.45; 95% confidence interval [CI], 0.09-2.21). When anticoagulation was analyzed as a time-varying covariate, the risk of any ICH did not differ between DOAC- and LMWH-treated patients (HR, 0.98; 95% CI, 0.28-3.40). PANWARDS score was not associated with ICH risk. This international 2-center study suggests comparable safety of LMWH and DOACs in patients with brain metastases.

Vaping is popular among adolescents. Previous research has explored sources of information and influence on youth vaping, including marketing, ads, family, peers, social media, and the internet. This research endeavors to expand understanding of peer influence. Our hypothesis is that friends’ influence on teen vapers’ first electronic nicotine delivery systems (ENDS) use varies by demographic variables and awareness of ENDS advertising. In August–October 2017, youth (n = 3174) aged 13–18 completed an online survey to quantify ENDS behaviors and attitudes and were invited to participate in follow-up online research in November-December 2017 to probe qualitative context around perceptions and motivations (n = 76). This analysis focused on the ENDS users, defined as having ever tried any ENDS product, from the survey (n = 1549) and the follow-up research (n = 39). Among survey respondents, friends were the most common source of vapers’ first ENDS product (60%). Most survey respondents tried their first ENDS product while “hanging out with friends” (54%). Among follow-up research participants, the theme of socializing was also prominent. ENDS advertising and marketing through social media had a strong association with friend networks; in fact, the odds of friends as source of the first vaping experience were 2 times higher for those who had seen ENDS ads on social media compared with other types of media. The influence of friends is particularly evident among non-Hispanic Whites, Hispanics/Latinos, those living in urban areas, those living in high-income households, those with higher self-esteem, and those who experiment with vaping. These findings support the premise that peer influence is a primary social influencer and reinforcer for vaping. Being included in a popular activity appears to be a strong driving force.

Abstract Objectives The purpose of this study was to assess the radiological change patterns in skull base meningiomas after conventionally fractionated stereotactic radiotherapy (CFSRT) to determine a simple and valid method to assess the tumor response. Materials and methods Forty-one patients with a benign skull base meningioma treated by CFSRT from March 2007 to August 2015 were retrospectively evaluated. We measured tumor volume (TV), long-axis diameter (LD), and short-axis diameter (SD) on both pre-treatment images and follow-up images of 1, 3, and 5 years after CFSRT, respectively. The paired t test was used to detect differences in the LD and SD change rates. Spearman’s correlation coefficients were calculated to evaluate relationships between the TV and the diameters changes. Results The number of available follow-up MRIs that was performed at 1, 3, and 5 years after the CFSRT was 41 (100%), 34 (83%), and 23 (56%), respectively. The change rates of SD were significantly higher than those of LD at every time point and more strongly correlated with the change rates of tumor volume at 3 and 5 years after CFSRT. Conclusions SD may be useful as a simple indicator of the tumor response for skull base meningioma after CFSRT. Key Points • The change rate in short-axis diameter is a useful and simple indicator of the response of skull base meningioma to conventionally fractionated stereotactic radiotherapy. • Conventionally fractionated stereotactic radiotherapy for skull base meningioma achieved excellent 5-year local control.

Abstract Background The ipsilateral olecranon with associated radial neck fractures does not include in the Bado classification of Monteggia fractures and equivalent lesions. The primary aims of this retrospective multicenter study were to characterize this type of injury and, noting its unique properties, evaluate the results of the treatment, determine the prognostic factors that influence the radiological and clinical outcome, and also give treatment strategies. Methods Between July 2011 and July 2016, forearm fracture patient charts were retrospectively reviewed from seven pediatric trauma centers. Patients diagnosed with ipsilateral olecranon with associated radial neck fractures and followed up for at least 24 months were included. Fracture characteristics, treatment, outcome, and complications were assessed. The clinical outcome of treatments was evaluated by the Mayo Elbow Performance Score (MEPS) and the Flynn criteria. Fisher’s exact test and ANOVA test were used; significance was defined as P < 0.05. Results One hundred thirty-seven consecutive patients (54 girls and 83 boys) from 8292 forearm fractures patients, the mean age of 7.5 years (1.5 to 14.8), with fractures of the ipsilateral olecranon with associated radial neck fractures were identified. One hundred twenty-five patients had radiologic and clinical follow-up. According to a simplified classification system with “operate” and “don’t operate” groups, including five subtypes proposed in this study, ipsilateral olecranon with associated radial neck fractures subtypes could be classified with significantly different characteristics and outcome in treatment and complications. Conclusions Fractures of the ipsilateral olecranon associated with the radial neck are not so rare as previously reported. Complications and poor outcomes were easy to encounter without knowing this type of fracture. Appropriate treatment strategies could be made according to a simple classification system based on the treatment result of follow-up. Level of evidence Retrospective comparative study; Level III

Tuberculous Tenosynovitis

Musculoskeletal system is involved in 1-5% of extrapulmonary cases of tuberculosis. Tuberculous tenosynovitis is a rare form of musculoskeletal tuberculosis. Tuberculosis of the tendon sheath in the hand has been seen in a few cases. Involvement of the tendons of the leg is less common. Diagnosis is not easy as there are no specific clinical symptoms or signs. A 33-year-old male presented with painful swelling in the distal right lower limb that caused restriction of movement. Imaging studies showed inflammation and infection of the extensor digitorium longus and tibialis anterior tendons. Histopathological studies showed a necrotizing granulomatous inflammation in the synovial tissue. A diagnosis of tuberculosis was made and medical treatment was initiated that proved successful. Patient remained infection-free at 26-month follow-up examination.

High Cervical

BackgroundMost cervical dissections are treated with anticoagulation or antiplatelet agents with very good results; however, some patients may benefit from endovascular intervention. High cervical and skull base dissections are often more challenging to treat because of the distal location and tortuous anatomy. The Pipeline Embolization Device (PED) may be a reasonable treatment option for this indication.ObjectivesTo report a case series of patients treated with the PED for high cervical and skull base dissections, focusing on their presentation, indications for treatment, dissection revascularization success, and pseudoaneurysm obliteration evaluated by imaging, and to review available pertinent literature.MethodsWe retrospectively reviewed all cases of high cervical and skull base dissections treated with a PED at our institution. Patient clinical characteristics, presentation, procedural and follow-up imaging, and clinical course were analyzed to evaluate for procedure complications, dissection revascularization success, pseudoaneurysm obliteration, and clinical outcome.ResultsThis is a retrospective case series including 11 patients with 13 carotid dissections treated in our center. There were nine traumatic and four spontaneous dissections. The most common presentation was cerebrovascular accident/transient ischemic attack (CVA/TIA; 5 patients) and headache/face pain (4 patients). Eleven dissections were associated with pseudoaneurysms. Three patients failed medical management with anticoagulation, although flow-limiting stenosis was the main indication for endovascular intervention. Up to three PEDs per vessel were deployed. Angioplasty was used in 10 cases. Complete revascularization (<10% residual stenosis) was achieved in 91% of vessels and 50% of pseudoaneurysms were completely or near completely obliterated immediately after PED(s) deployment. Proximal iatrogenic dissection was the only intraoperative complication. Follow-up imaging was available for nine treated vessels and demonstrated patent PEDs without significant in-stent stenosis up to 9 months after intervention. 75% of pseudoaneurysms were completely obliterated at follow-up. One PED partially collapsed but had no neurological consequences. There were no new CVA/TIAs.ConclusionsOur initial experience with treatment of high cervical and skull base dissections with the PED appears to show that this technique may be a safe and viable treatment option. However, long-term results are needed to fully evaluate the efficacy of such treatment.

OBJECTIVE The objective of this study was to identify the natural history and clinical predictors of postoperative recurrence of skull base and non–skull base meningiomas. METHODS The authors performed a retrospective hospital-based study of all patients with meningioma referred to their institution from September 1993 to January 2014. The cohort constituted both patients with a first-time presentation and those with evidence of recurrence. Kaplan-Meier curves were constructed for analysis of recurrence and differences were assessed using the log-rank test. Cox proportional hazard regression was used to identify potential predictors of recurrence. RESULTS Overall, 398 intracranial meningiomas were reviewed, including 269 (68%) non–skull base and 129 (32%) skull base meningiomas (median follow-up 30.2 months, interquartile range [IQR] 8.5–76 months). The 10-year recurrence-free survival rates for patients with gross-total resection (GTR) and subtotal resection (STR) were 90% and 43%, respectively. Skull base tumors were associated with a lower proliferation index (0.041 vs 0.062, p = 0.001), higher likelihood of WHO Grade I (85.3% vs 69.1%, p = 0.003), and younger patient age (55.2 vs 58.3 years, p = 0.01). Meningiomas in all locations demonstrated an average recurrence rate of 30% at 100 months of follow-up. Subsequently, the recurrence of skull base meningiomas plateaued whereas non–skull base lesions had an 80% recurrence rate at 230 months follow-up (p = 0.02). On univariate analysis, a prior history of recurrence (p < 0.001), initial WHO grade following resection (p < 0.001), and the inability to obtain GTR (p < 0.001) were predictors of future recurrence. On multivariate analysis a prior history of recurrence (p = 0.02) and an STR (p < 0.01) were independent predictors of a recurrence. Assessing only patients with primary presentations, STR and WHO Grades II and III were independent predictors of recurrence (p < 0.001 for both). CONCLUSIONS Patients with skull base meningiomas present at a younger age and have less aggressive lesions overall. Extent of resection is a key predictor of recurrence and long-term follow-up of meningiomas is necessary, especially for non–skull base tumors. In skull base meningiomas, recurrence risk plateaus approximately 100 months after surgery, suggesting that for this specific cohort, follow-up after 100 months can be less frequent.

Background Pediatric pituitary adenoma is a rare skull base neoplasm, accounting for 3% of all intracranial neoplasms in children and 5% of pituitary adenomas. Compared with pituitary tumors in adults, secreting tumors predominate and longer disease trajectories are expected due to the patient age resulting in a natural history and treatment paradigm that is complex and controversial. Objectives The aims of this study were to describe a large, single-institution series of pediatric pituitary adenomas with extensive long-term follow-up and to conduct a systematic review examining outcomes after pituitary adenoma surgery in the pediatric population. Methods The study cohort was compiled by searching institutional pathology and operative reports using diagnosis and site codes for pituitary and sellar pathology, from 1956 to 2016. Systematic review of the English language literature since 1970 was conducted using PubMed, MEDLINE, Embase, and Google Scholar. Results Thirty-nine surgically managed pediatric pituitary adenomas were identified, including 15 prolactinomas, 14 corticotrophs, 7 somatotrophs, and 4 non-secreting adenomas. All patients underwent transsphenoidal resection (TSR) as the initial surgical treatment. Surgical cure was achieved in 18 (46%); 21 experienced recurrent/persistent disease, with secondary treatments including repeat surgery in 10, radiation in 14, adjuvant pharmacotherapy in 11, and bilateral adrenalectomy in 3. At the last follow-up (median 87 months, range 3–581), nine remained with recurrent/persistent disease (23%).Thirty-seven publications reporting surgical series of pediatric pituitary adenomas were included, containing 1,284 patients. Adrenocorticotropic hormone (ACTH)-secreting tumors were most prevalent (43%), followed by prolactin (PRL)-secreting (37%), growth hormone (GH)-secreting (12%), and nonsecreting (7%). Surgical cure was reported in 65%. Complications included pituitary insufficiency (23%), permanent visual dysfunction (6%), chronic diabetes insipidus (DI) (3%), and postoperative cerebrospinal fluid (CSF) leak (4%). Mean follow-up was 63 months (range 0–240), with recurrent/persistent disease reported in 18% at the time of last follow-up. Conclusion Pediatric pituitary adenomas are diverse and challenging tumors with complexities far beyond those encountered in the management of routine adult pituitary disease, including nuanced decision-making, a technically demanding operative environment, high propensity for recurrence, and the potentially serious consequences of hypopituitarism with respect to fertility and growth potential in a pediatric population. Optimal treatment requires a high degree of individualization, and patients are most likely to benefit from consolidated, multidisciplinary care in highly experienced centers.
