Stereotactic radiosurgery for cerebellopontine meningiomas: a systematic review and meta-analysis.

OBJECTIVE: To (1) measure surgical outcomes associated with stereotactic radiosurgery treatment of cerebellopontine angle meningiomas, and (2) determine if differences in radiation dosages or preoperative tumor volumes affect surgical outcomes. METHODS: A systematic search was performed on the PubMed, Medline, Embase and Cochrane Library databases searching for patients under stereotactic radiosurgery for meningiomas of the cerebellopontine angle. After data extraction and Newcastle-Ottawa scale quality assessment, meta-analysis of the data was performed with Review Manager 3.4.5. RESULTS: In total, 6 studies including 406 patients were included. Postprocedure, patients had minimal cranial nerve complications while having an overall tumor control rate of 95.6%. Complications were minimal with facial nerve deficits occurring in 2.4%, sensation deficits of the trigeminal nerve in 4.0%, hearing loss in 5.9%, hydrocephalus in 2.0% and diplopia in 2.6% of all patients. Individuals with tumors extending into the internal auditory canal extension did not have significantly increases in hearing loss. There was a higher likelihood of tumor regression on postprocedure imaging in studies with a median prescription dose of >13 Gy (RR 1.27 [95% CI 1.04-1.56, p = 0.0225). There was no evidence of publication bias detected. CONCLUSIONS: Radiosurgery is an effective modality for offering excellent tumor control of CPA meningiomas while allowing for only minimal complications postprocedure. A higher prescription dose may achieve higher tumor regression at follow up. Future studies should aim at establishing and optimizing accurate dosimetric guidelines for this patient population.

The Potential Impact of Food Insecurity in an Urban Trauma Population.

BACKGROUND: Food insecurity (FI) has been defined as a lack of consistent access to enough food for a healthy active lifestyle. As of 12.7% of the United States are suffering from FI, which has been correlated with increased hospital costs and poorer health outcomes. Currently, limited data exists examining the relationship between trauma populations and FI despite both having similar root causes. We sought to determine this and validate a screening tool for FI in this population. METHODS: A cross-sectional survey study of trauma patients was conducted at a level 1 trauma center in Atlanta, Georgia. Survey questions included the first two items of the Core Food Security Module. Zip codes were used to determine FI, defined by the USDA Food Access Research and compared to individual participant survey responses. Binary classification test metrics were calculated to validate the two items as a screening tool in this population. RESULTS: The cohort included 136 patients, of which the majority were black (60.3%) and male (60.3%). Thirty-one respondents affirmed food security (22.8%) despite over half (51.5%) living in a food insecure community. The sensitivity and specificity for this screening to predict FI were 25 and 80%, respectively. CONCLUSION: Although the specificity is high, this screening tool has a low sensitivity, accuracy, NPV, and PPV to determine food insecurity in this population. Community-level statistics suggests that food insecurity is a significant public problem amongst trauma patients. Prevention efforts should, therefore, aim to address both issues simultaneously.

Ergonomics and Work-Related Musculoskeletal Disorders: Characteristics Among Female Interventionists.

Interventional radiology is a procedural specialty that performs minimally invasive operations under image guidance. Currently, there are inadequate ergonomic protocols for work-related musculoskeletal disorder (WMSD) prevention in interventional radiology (IR), and there is a paucity of information discerning gender differences in WMSDs. This article reviews current literature that addresses WMSDs in female physicians practicing interventional and fluoroscopic procedures, including interventional radiology, interventional cardiology, electrophysiology, vascular surgery, orthopedic surgery, neurosurgery, and gastroenterology. We searched PubMed and EBSCOhost databases for ergonomic studies that reported female physician WMSDs in the specialties listed above. After a thorough evaluation for inclusion based on eligibility criteria, 11 studies were included. From this search, there was poor female representation, averaging 25.7% of respondents. Several characteristics identified across the studies were that women were generally shorter, wore smaller glove sizes, and were younger than their male colleagues. Seventy-two percent of female proceduralists reported WMSDs versus 46.6% of their male colleagues. Additionally, women may experience more upper extremity pain than lumbar pain, which men commonly reported. Potential contributing factors to WMSDs are the size and design of procedural tools and the possible predisposition of female physicians to experience upper extremity WMSDs while performing the same operations as men. As more women enter medicine and pursue careers in procedural fields like interventional radiology, it is essential to address these discrepancies and develop ergonomically sound solutions for women.

High Frequency 10 kHz Spinal Cord Stimulation as a First Line Programming Option for Patients With Chronic Pain: A Retrospective Study and Review of the Current Evidence.

Introduction Neuromodulation is an evolving and increasingly popular therapy for chronic pain management. Recent data suggest that novel waveforms have demonstrated greater benefit over traditional spinal cord stimulation (SCS). The authors conducted a retrospective review of patients undergoing high-frequency 10 kHz SCS at a single tertiary medical center for the purpose of contributing further evidence to this growing body of data. The literature of high-frequency SCS published to date was also reviewed. Methods A retrospective chart review was performed for patients with chronic pain syndrome, including failed back surgery syndrome and sciatica alone, who underwent high-frequency SCS at 10 kHz. This data was analyzed using R software (R Foundation for Statistical Computing, Vienna, Austria) for statistical analysis. The PubMed database was searched for relevant articles using the search terms "high frequency," "10 kHz," and "spinal cord stimulation." All relevant studies conducted to date were included in this literature review. Results Twenty-one patients had complete follow-up data and were included in this study. Of the 21 patients, 85.7% subjectively reported post-operative pain relief while 71.4% of the total patients reported pain relief by ≥ 50%. There was a statistically significant decrease in mean VAS scores from pre-operative to 12-months post-operative (8.52 vs 4.37, p < 0.001). Additionally, 76.5% of patients subjectively reported improvements in sleep and activities of daily living. Recent studies indicate that high-frequency SCS appears to be a viable option for delivering quality pain relief in patients for chronic regional pain syndrome, failed back surgery syndrome, sciatica, and also pain in the upper cervical region of the spine. Conclusion This article provides evidence both with the authors' own institutional data and from the currently published literature for the efficacy of using high-frequency SCS at 10 kHz as a first-line programming option for patients undergoing SCS.

Hemothorax and Pneumothorax Secondary to Costal Involvement in Hereditary Multiple Exostoses: A Systematic Review of Reported Cases in the Literature.

Hereditary multiple exostoses (HME) are an autosomal dominant skeletal disorder characterized by the development of multiple benign osteochondromas (exostoses) that frequently involve long bones of the body. Less commonly, the ribs are a site of involvement, and long-term friction between an exostosis and pleura can produce a hemothorax or pneumothorax. The purpose of this study is to provide a comprehensive review of existing literature on pneumothorax or hemothorax secondary to costal exostosis in HME patients. We reviewed the databases of PubMed and Embase and included data as current as of February 15, 2021. All case reports included cases of hemothorax or pneumothorax in patients with a known personal or family history of HME. After evaluation for inclusion based on eligibility criteria, 18 cases were included. The average age at presentation was 11.7 years (range: 3-32), and most patients were male (83%). Hemothoraces occurred in 15 cases, while pneumothoraces occurred in three cases. All cases were evaluated using chest X-ray and CT scan, and the majority of the cases were treated with surgical resection of the exostosis, either with video-assisted thoracoscopic surgery (VATS; 61%) or thoracotomy (22%). Outcomes were successful with no cases of recurrence after surgical intervention. Although rare, costal exostosis should be considered as a differential in patients presenting with pneumothorax or hemothorax and past medical history or physical exam findings suggestive of HME. Immediate evaluation and surgical intervention to resect costal exostosis are essential to reduce the risk of recurrent life-threatening injury.

Timing of Surgical Intervention for Dysphagia in Patients With Diffuse Idiopathic Skeletal Hyperostosis: A Systematic Review and Meta-Analysis.

STUDY DESIGN: This was a systematic review and meta-analysis. OBJECTIVE: The objective was (1) to measure rates of successful resolution of dysphagia in patients after undergoing surgical intervention for diffuse idiopathic skeletal hyperostosis (DISH); and (2) to determine if older age, longer duration of preoperative symptoms, or increased severity of disease was correlated with unsuccessful surgical intervention. SUMMARY OF BACKGROUND DATA: DISH, also known as Forestier disease, is an enthesopathy affecting up to 35% of the elderly population. Many patients develop osteophytes of the anterior cervical spine, which contribute to chronic symptoms of dysphagia causing debilitating weight loss and possibly resulting in the placement of a permanent gastrostomy feeding tube. For patients that fail conservative medical management, an increase in surgical interventions have been reported in the literature in the last 2 decades. MATERIALS AND METHODS: A systematic search was performed on PubMed, Medline, Cochrane Library, and Embase. Studies measuring outcomes after surgical intervention for patients with dysphagia from DISH were selected for inclusion. Two independent reviewers screened and assessed all literature in accordance with Cochrane systematic reviewing standards. RESULTS: In total, 22 studies reporting 119 patients were selected for inclusion. Successful relief of dysphagia was obtained in 89% of patients after surgical intervention. Failure to relieve dysphagia was associated with increased length of symptoms preoperatively (P<0.01) using logistic regression. Patients with more severe preoperative symptoms also seem to have an increased risk for treatment failure (risk ratio, 2.86; 95% confidence interval, 1.19-6.85; P=0.02). Treatment failure was not associated with patient age, use of intraoperative tracheostomy, implementation of additional fusion procedures, level of involved segments, or number of involved segments. CONCLUSIONS: Patients undergoing surgical intervention have a higher likelihood of failing surgery with increasing preoperative symptom length and increased preoperative symptom severity. LEVEL OF EVIDENCE: Level III.
