Duration of effectiveness of coblation for recurrent epistaxis in hereditary hemorrhagic telangiectasia.

INTRODUCTION: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease leading to recurrent epistaxis, telangiectasias, and/or visceral arteriovenous malformations. Multiple treatment methods, including both pharmacologic and surgical, are described to be effective in managing symptomatic HHT. Few report the duration of symptom improvement for each of these treatment methods. This study aims to analyze the duration of effectiveness of coblation treatment for recurrent epistaxis in those with HHT. METHODS: Retrospective single-center chart review was completed for patients diagnosed with HHT who underwent coblation treatment by the same otolaryngologist from December 2009 to November 2021. Demographic information was collected along with whether local Bevacizumab was used during each treatment. Months between treatment coblation sessions was used as a surrogate for duration of treatment effectiveness. Descriptive statistics were used for analysis alongside quantitative statistical analysis. RESULTS: Over the course of 12 years, 57 patients (24 female, 42.11%) with HHT underwent a total number of 150 coblation treatments. The average age at initial coblation was 59 years (29-88) with an average follow-up time of 5 years (1-12 years). Of the 150 coblations, 30 treatments (20%) included bevacizumab injections into the nasal cavity. The average duration of treatment effectiveness across all 150 treatment sessions was 24.5 months (1-87 months). Of the 26 patients (46%) that underwent multiple coblation treatments, the overall average duration of coblation effectiveness was 16.4 months (1-72 mos). When Bevacizumab was utilized, the average duration of effectiveness was 18.3 months (3-62 mos), while the average duration of effectiveness for treatments without Bevacizumab was 15.7 months (1-87 mos, p > 0.251). Further, there was no correlation between duration of treatment effectiveness and age, sex, and race; yet,there was a significant negative correlation between the use of tobacco and duration of coblation effectiveness (p = 0.0202). CONCLUSIONS: Coblation is an effective treatment option for the management of epistaxis in patients with HHT with duration of benefit lasting approximately 2 years. The use of Bevacizumab did not add to the duration of treatment benefit. Further, the duration of benefit was negatively impacted by smoking history.

Chiari Malformation Type 1 and Syringomyelia in a Patient With Prior Surgically-Treated Sagittal Synostosis Effectively Treated With Posterior Cranial Vault Distraction Osteogenesis.

ABSTRACT: The presenting report describes the use of a posterior cranial vault distraction procedure in resolving a Chiari malformation with associated syringomyelia following a surgically-treated nonsyndromic craniosynostosis. Chiari malformations are typically treated with posterior fossa decompression with or without expansion duraplasty. The objective of this report is to describe the effectiveness in resolving both Chiari malformation and secondary syringomyelia with posterior cranial vault distraction osteogenesis. A 5-year-old male, with a history of surgery for sagittal synostosis during infancy, presented with daily severe headaches and dysesthesias in the hands and feet. Imaging demonstrated a copper-beaten calvarium and a Chiari 1 malformation with a 7 mm diameter C4-T1 syrinx. He underwent posterior cranial vault distraction osteogenesis over 3 months to increase his intracranial volume. The patients' headaches improved significantly, and his dysesthesias resolved postoperatively. A magnetic resonance imaging performed 7 months after completion of distraction demonstrated resolution of the Chiari malformation and decompression of his syrinx. A computed tomography scan at 9 months postdistraction showed resolution of the copper-beaten calvarium. Patients with a history of craniosynostosis can develop inadequate cranial volume over time due to abnormal skull growth, leading to secondary Chiari malformation with or without syringomyelia. Posterior vault distraction is an effective strategy to address these conditions and can be employed later in childhood to treat the underlying pathology. The mechanism potentially expands both calvarium and dura, which in turn addresses both the Chiari malformation and secondary syringomyelia.

Low Rate of Intrathecal Baclofen Pump Catheter-Related Complications: Long-Term Study in Over 100 Adult Patients Associated With Reinforced Catheter.

OBJECTIVES: Intrathecal baclofen (ITB) is a cost-effective therapy for patients with severe spasticity. The most common complications are catheter-related complications (CRCs) including kinking/occlusion, blockage, migration, fracture, disconnection, and CSF leak. Our objective was to determine the CRC rate in a large cohort of adults with newly implanted ITB pump systems with polymer reinforced silicone catheters. MATERIALS AND METHODS: This is a retrospective study of a prospectively maintained database consisting of patients who had undergone implantation of ITB pump systems with Ascenda (Medtronic, Minneapolis) catheters from 2013 to 2020. Over this seven-year period, 141 patients underwent ITB pump system implantations; 126 of which had a minimum of one-year follow-up. RESULTS: The 126 patients with a minimum of one year follow-up (average 43 month; range 12-89), had an average age of 51 years (63% male). Severe spasticity was due to spinal cord injury (38%), traumatic brain injury (15%), cerebral palsy (13%), multiple sclerosis (11%), stroke (10%), and other (13%). Nine (7.1%) CRCs occurred in 7 (5.6%) patients (median 6 mo. post-implant): 5 intrathecal catheter occlusions (range 3-52 months post-implant), two fractures in one patient (6 months), one disconnection at the catheter pump interface (2 months), and one due to kinking at 84 months No migrations occurred. CONCLUSIONS: Reported CRCs have been high for ITB pump systems. Ours is the first large cohort, long-term study of CRCs related to reinforced catheters; additionally, our low CRC rate compares favorably to previously published data. Thus, implantation of reinforced catheters may be associated with a low CRC rate.

Impacts of Socioeconomic Status on Dentoalveolar Trauma.

INTRODUCTION: Children sustain dentoalveolar trauma and lose teeth at the same rate regardless of socioeconomic status; however, debate surrounds these rates in adults. It is known socioeconomic status plays a major role in access and treatment in health care. This study aims to clarify the role of socioeconomic status as a risk factor for dentoalveolar trauma in adults. METHODS: A single center retrospective chart review took place from January 2011 through December 2020 for patients requiring oral maxillofacial surgery consultation in the emergency department, due to either dentoalveolar trauma (Group 1) or other dental condition (Group 2). Demographic information including age, sex, race, marital status, employment status, and type of insurance were collected. Odds ratios were calculated by chi-square analysis with significance set at P < 0.05. RESULTS: Over the course of 10 years, 247 patients (53% female) required an oral maxillofacial surgery consultation, with 65 (26%) sustaining dentoalveolar trauma. Within this group, there were significantly more subjects who were Black, single, insured with Medicaid, unemployed, and 18 - 39 years old. In the nontraumatic control group, there were significantly more subjects who were White, married, insured with Medicare, and 40 - 59 years old. CONCLUSIONS: Among those seen in the emergency department requiring an oral maxillofacial surgery consultation, those with dentoalveolar trauma have an increased likelihood of being single, Black, insured with Medicaid, unemployed, and 18 - 39 years old. Further research is needed to determine causality and the most critical/influential socioeconomic status factor in sustaining dentoalveolar trauma. Identifying these factors can assist in developing future community-based prevention and educational programs.

MedCDI: A technology-based documentation and quality improvement initiative in neurosurgery.

Background: Clinical documentation of patient care alters coding accuracy of Medicare Severity Diagnosis-Related Groups (MS-DRGs), expected mortality, and expected length of stay (LOS) which impact quality metrics. We aimed to determine if neurosurgical quality metrics could be improved by facilitating accurate documentation and subsequently developed a mobile application and educational video to target areas of opportunity. Methods: Vizient software was used to analyze MS-DRGs and expected LOS for sample of patients requiring surgery for spinal pathology, brain tumors, and subarachnoid hemorrhage (SAH) between January 2019 and August 2021. Chart reviews were conducted to discover variables missed by documenting provider and/or coder. Results: Review of 114 spinal surgeries, 20 brain tumors, and 53 SAH patients revealed at least one additional variable impacting LOS in 43% of spine, 75% of brain tumor, and 92% of SAH patients, with an average of 1 (1.25), 2 (1.75), and 3 (2.89) new variables, respectively. Recalculated expected LOS increased by an average of 0.86 days for spine, 3.08 for brain tumor, and 6.46 for SAH cases. Conclusion: Efforts to accurately document patient care can improve quality metrics such as expected LOS, mortality, and cost estimates. We determined several missing variables which impact quality metrics, showing opportunity exists in neurosurgical documentation improvement. Subsequently, we developed an educational video and mobile-supported application to specifically target these variables. To the best of our knowledge, this represents the first initiative to utilize the proven powers of mobile phones in health care toward the novel application of specifically improving neurosurgical quality metrics.

Pediatric middle meningeal artery embolization for chronic subdural hematoma: A case report.

BACKGROUND: The most common neuroradiological finding in pediatric nonaccidental trauma (NAT) is subdural hematoma (SDH). Management options for pediatric SDH range from conservative clinical surveillance to craniotomy or decompressive craniectomy. The middle meningeal artery (MMA) indirectly feeds the hematoma; thus, MMA embolization is an alternative or adjunct to current surgical treatments in adults. Herein, we present, to the best of our knowledge, the first reported case of successful MMA embolization in a pediatric patient as an adjunct to current standard treatment for chronic SDH (cSDH). CASE DESCRIPTION: An 18-month-old male with a history of NAT presented at 5 months of age with an acute right parietal skull fracture and bilateral SDH treated with burr hole drainage. He was lost to follow-up until 15 months of age with an increased head circumference and new dysconjugate gaze. Imaging revealed a right-sided cSDH and underwent craniotomy. Six-week follow-up revealed significant improvement in the SDH but cSDH remained at the periphery of the craniotomy's reach. The patient symptoms continued. The right-sided MMA embolization was offered as option to avoid repeat craniotomy. Follow-up CTs at 2 weeks, 3 months, and 6 months postprocedure revealed decrease of cSDH size and density. At 8-month follow-up, the patient continued to meet developmental milestones with near resolution of his dysconjugate gaze. CONCLUSION: This case report details the first successful use of MMA embolization in the treatment of pediatric cSDH as an adjunct to standard treatment. Further investigation of MMA embolization in pediatrics should be made to expand options available for cSDH in this patient population.

Reversal of cognitive, behavioral, and language impairments after the left frontal arachnoid cyst fenestration in a pediatric patient.

BACKGROUND: Arachnoid cysts (ACs) are cerebrospinal fluid-containing cysts located between the surface of the brain or spinal cord and arachnoid layer of the leptomeninges. ACs have been known to cause cognitive, language, and behavioral deficits and currently there is no standard treatment paradigm. Surgical indications include papilledema, increasing growth with mass effect causing neurological deficit, or rapid head growth, however, cognitive symptoms related to mass effect may not always be considered. CASE DESCRIPTION: We present a 3-year-old male with an AC of the left anterior fossa causing frontal lobe compression with resultant behavioral, language, and cognitive deficits. CONCLUSION: Surgical intervention for AC decompression may be indicated when there are cognitive, behavioral, or language delays related to the mass effect and location of the AC. Neuropsychiatric testing or more advanced imaging studies may further support surgical treatment. After craniotomy for fenestration of the left frontal AC, there was drastic improvement in cognitive, language, and behavioral symptoms in our pediatric patient.

Classification of Comprehensive Neuro-Ophthalmologic Measures of Postacute Concussion.

Importance: Symptom-based methods of concussion diagnosis in contact sports result in underdiagnosis and repeated head injury exposure, increasing the risk of long-term disability. Measures of neuro-ophthalmologic (NO) function have the potential to serve as objective aids, but their diagnostic utility is unknown. Objective: To identify NO measures that accurately differentiate athletes with and without concussion. Design, Setting, and Participants: This cohort study was conducted among athletes with and without concussion who were aged 17 to 22 years between 2016 and 2017. Eye movements and cognitive function were measured a median of 19 days after injury among patients who had an injury meeting the study definition of concussion while playing a sport (retrospectively selected from a concussion clinic), then compared with a control group of participants without concussion (enrolled from 104 noncontact collegiate athlete volunteers without prior head injury). Data analysis was conducted from November 2019 through May 2020. Exposure: Concussion. Main Outcomes and Measures: Classification accuracy of clinically important discriminator eye-tracking (ET) metrics. Participants' eye movements were evaluated with a 12-minute ET procedure, yielding 42 metrics related to smooth pursuit eye movement (SPEM), saccades, dynamic visual acuity, and reaction time. Clinically important discriminator metrics were defined as those with significantly different group differences and area under the receiver operator characteristic curves (AUROCs) of at least 0.70. Results: A total of 34 participants with concussions (mean [SD] age, 19.7 [2.4] years; 20 [63%] men) and 54 participants without concussions (mean [SD] age, 20.8 [2.2] years; 31 [57%] men) completed the study. Six ET metrics (ie, simple reaction time, discriminate reaction time, discriminate visual reaction speed, choice visual reaction speed, and reaction time on 2 measures of dynamic visual acuity 2) were found to be clinically important; all were measures of reaction time, and none were related to SPEM. Combined, these 6 metrics had an AUROC of 0.90 (95% CI, 0.80-0.99), a sensitivity of 77.8%, and a specificity of 92.6%. The 6 metrics remained significant on sensitivity testing. Conclusions and Relevance: In this study, ET measures of slowed visual reaction time had high classification accuracy for concussion. Accurate, objective measures of NO function have the potential to improve concussion recognition and reduce the disability associated with underdiagnosis.
