RESUMO

INTRODUCTION: Brain cancer is the leading cause of cancer-related deaths in children and the majority of childhood brain tumors are diagnosed without determination of their underlying etiology. Little is known about risk factors for childhood brain tumors in Vietnam. The objective of this case-control study was to identify maternal and perinatal factors associated with brain tumors occurring in young Vietnamese children and adolescents. METHODS: We conducted a hospital-based case-control study at Viet Duc University Hospital in Hanoi, Vietnam. Cases consisted of children with brain tumors aged 0-14 years old admitted to the hospital from January 2020 to July 2022 while the controls were age and sex-matched hospitalized children diagnosed with head trauma. Perinatal characteristics were abstracted from hospital medical records and maternal medical, behavioral, and sociodemographic factors were collected through in-person interviews. Conditional logistic regression models were used to examine maternal and perinatal factors associated with childhood brain tumors. RESULTS: The study sample included 220 children (110 cases and 110 controls) whose average age was 8.9 years and 41.8% were girls. Children born to mothers aged greater than 30 years at the time of the child's birth had a higher risk of childhood brain tumors compared to those born to mothers aged from 18 to 30 years old (OR = 2.55; 95% CI: 1.13-5.75). Additionally low maternal body mass index prior to the current pregnancy of <18.5 kg/m2 significantly increased the odds of having a child with a brain tumor in relation to normal maternal body mass index from 18.5-22.9 kg/m2 (OR = 3.19; 95% CI: 1.36 - 7.50). CONCLUSION: Advanced maternal age and being markedly underweight were associated with an increased odds of having a child with a brain tumor. A population-based study with larger sample size is needed to confirm and extend the present findings.

RESUMO

An important question is what genes govern the differentiation of plant embryos into suspensor and embryo proper regions following fertilization and division of the zygote. We compared embryo proper and suspensor transcriptomes of four plants that vary in embryo morphology within the suspensor region. We determined that genes encoding enzymes in several metabolic pathways leading to the formation of hormones, such as gibberellic acid, and other metabolites are up-regulated in giant scarlet runner bean and common bean suspensors. Genes involved in transport and Golgi body organization are up-regulated within the suspensors of these plants as well, strengthening the view that giant specialized suspensors serve as a hormone factory and a conduit for transferring substances to the developing embryo proper. By contrast, genes controlling transcriptional regulation, development, and cell division are up-regulated primarily within the embryo proper. Transcriptomes from less specialized soybean and Arabidopsis suspensors demonstrated that fewer genes encoding metabolic enzymes and hormones are up-regulated. Genes active in the embryo proper, however, are functionally similar to those active in scarlet runner bean and common bean embryo proper regions. We uncovered a set of suspensor- and embryo proper-specific transcription factors (TFs) that are shared by all embryos irrespective of morphology, suggesting that they are involved in early differentiation processes common to all plants. Chromatin immunoprecipitation sequencing (ChIP-Seq) experiments with scarlet runner bean and soybean WOX9, an up-regulated suspensor TF, gained entry into a regulatory network important for suspensor development irrespective of morphology.

RESUMO

PURPOSE: The purpose of this article and accompanying video is to demonstrate a transorbital endoscopic approach for accessing the pterygopalatine fossa (PPF). This technique does not require a skin incision, avoids dissection of critical neurovascular structures, and utilizes a comparatively small osteotomy. The 2 cases presented in this article highlight the utility of a transorbital endoscopic approach for accessing an anatomic region that has traditionally required more invasive techniques to reach. METHODS: Description of surgical technique with 2 illustrative clinical cases and accompanying surgical video. RESULTS: Surgical technique: A trans-conjunctival approach is taken to the inferior orbital rim, and a subperiosteal dissection is propagated posteriorly. The bone of the posterior orbital floor is then deroofed, and the superior portion of the posterior wall of the maxillary sinus is removed, allowing access to the PPF for an incisional biopsy. CASE: A 76-year-old male with a history of left cheek squamous cell carcinoma presented with progressive V2 paresthesia and an abnormally enhancing lesion in the left PPF on MRI. CASE: A 58-year-old male with no significant medical history presented with left facial numbness (V1-V3), ptosis, an abduction deficit, and decreased hearing. Contrast-enhanced MRI demonstrated an abnormally enhanced lesion in the left PPF extending to Meckel's cave.The transorbital approach described was used to successfully obtain a diagnostic biopsy in both cases. CONCLUSIONS: These cases highlight the utility of a transorbital endoscopic approach to the PPF as a less morbid alternative to traditional access. Patient selection is key to identifying appropriate cases.

RESUMO

PURPOSE: To report a case of a globular primary optic nerve sheath meningioma managed surgically with improvement in vision and review the literature for outcomes of purely intraorbital exophytic-globular primary optic nerve sheath meningiomas managed surgically. METHODS: A literature review was conducted using Google Scholar and PubMed with the search terms "primary optic nerve sheath meningioma," "surgery," "exophytic," and "globular." Articles were included if they were available in English. Individual cases from the reviewed articles were included if the tumor was purely intraorbital with a globular or exophytic morphology, was managed with total or subtotal surgical excision, and visual outcomes were reported. Cases were excluded if the tumor extended intracanalicularly or intracranially, tumor morphology was unknown, or surgical management consisted of biopsy, optic nerve sheath decompression, or optic canal decompression rather than tumor debulking. RESULTS: A total of 28 patients with intraorbital globular-exophytic primary optic nerve sheath meningiomas managed surgically have been reported in the literature. Vision improved in 29% (n = 8/28) and remained stable in 43% (n = 12/28) of patients. Furthermore, patients with good (Snellen notation ≥ 0.5) vision (n = 10) typically retained good vision postoperatively and at follow-up, with 1 patient experiencing a decline to poor (Snellen ≤0.1) vision at the last follow-up (92 months postoperatively). Similarly, patients with fair (Snellen notation >0.1 and <0.5) vision (n = 5) often improved to good vision (n = 3) or stayed at fair vision (n = 1), with 1 declining to poor vision at postoperative hospital discharge. CONCLUSIONS: Surgical management of exophytic or globular optic nerve meningiomas does not universally lead to vision loss and may be appropriate in select patients.

RESUMO

PURPOSE: To delineate specific imaging characteristics of solitary fibrous tumors, schwannomas, cavernous venous malformations, and well-circumscribed orbital lymphoma. METHODS: Patients undergoing excisional biopsy of solitary fibrous tumor, schwannomas, cavernous venous malformations, or well-circumscribed orbital lymphoma with preoperative MRIs available for review were identified at 3 academic centers in the United States and Australia. An exploratory statistical analysis was performed to identify important radiologic features, which were subsequently included in a random forest model. Histopathologic correlates were evaluated in representative cases. RESULTS: A total of 91 cases were included with a mean age of 52.9 ± 17.2 years. Nearly all solitary fibrous tumors were located in the anterior or mid orbit (87.5%) and they more commonly demonstrated intralesional heterogeneity on T2-weighted imaging (45.5%) ( p < 0.01). Compared with the other tumors, schwannomas tended to be intraconal (66.7%) and were often in the mid or posterior orbit (83.4%) ( p < 0.01). Cavernous venous malformations characteristically demonstrated progressive contrast enhancement (93.9%; p < 0.01). Most lesions in all 4 groups were hypointense on T1-weighted imaging (80%-100%; p = 0.14) and only well-circumscribed orbital lymphoma tended to also be hypointense on T2 (81.8%) ( p < 0.01). Finally, cases of lymphoma had significantly lower apparent diffusion coefficient ratios (0.9 ± 0.2) ( p < 0.001), while the other 3 groups were not significantly different from one another (cavernous venous malformations: 1.8 ± 0.4; schwannomas: 1.8 ± 0.5; and solitary fibrous tumor: 1.6 ± 0.6) ( p = 0.739). CONCLUSIONS: Key features that aid in the differentiation of these 4 tumors from one another include T2 intensity and homogeneity, early contrast-enhancement pattern, and ADC ratio.

RESUMO

OBJECTIVE: To describe the prevalence of blood pressure (BP) screening according to the 2017 American Academy of Pediatrics (AAP) guidelines and differences according to social vulnerability indicators. STUDY DESIGN: We extracted electronic health record data from January 1, 2018, through December 31, 2018, from the largest healthcare system in Central Massachusetts. Outpatient visits for children aged 3-17 years without a prior hypertension diagnosis were included. Adherence was defined by the American Academy of Pediatrics guideline (≥1 BP screening for children with a body mass index [BMI] of <95th percentile) and at every encounter for children with a BMI of ≥95th percentile). Independent variables included social vulnerability indicators at the patient level (insurance type, language, Child Opportunity Index, race/ethnicity) and clinic level (location, Medicaid population). Covariates included child's age, sex, and BMI status, and clinic specialty, patient panel size, and number of healthcare providers. We used direct estimation to calculate prevalence estimates and multivariable mixed effects logistic regression to determine the odds of receiving guideline-adherent BP screening. RESULTS: Our sample comprised 19 695 children (median age, 11 years; 48% female) from 7 pediatric and 20 family medicine clinics. The prevalence of guideline-adherent BP screening was 89%. In our adjusted model, children with a BMI of ≥95th percentile, with public insurance, and who were patients at clinics with larger Medicaid populations and larger patient panels had a lower odds of receiving guideline-adherent BP screening. CONCLUSIONS: Despite overall high adherence to BP screening guidelines, patient- and clinic-level disparities were identified.

RESUMO

BACKGROUND: The optimal approach to classifying multimorbidity burden in assessing treatment-associated outcomes using real-world data remains uncertain. We assessed whether 2 measurement approaches to characterize multimorbidity influenced observed associations of ß-blocker use with outcomes in adults with heart failure (HF). METHODS: We conducted a retrospective study on adults with HF from 4 integrated health care delivery systems. Multimorbidity burden was characterized by either (1) simple counts of chronic conditions or (2) a weighted multiple chronic conditions score using data from electronic health records. We assessed the impact of these 2 approaches to characterizing multimorbidity on associations between exposure to ß-blockers and subsequent all-cause death, hospitalization for HF, and hospitalization for any cause. RESULTS: The study population characterized by a count of chronic conditions included 9988 adults with HF who had a mean (SD) age of 76.4 (12.5) years, with 48.7% women and 24.7% racial/ethnic minorities. The cohort characterized by weighted multiple chronic conditions included 10,082 adults with HF who had a mean (SD) age of 76.4 (12.4) years, 48.9% women, and 25.5% racial/ethnic minorities. The multivariable associations of risks of death or hospitalizations for HF or for any cause associated with incident ß-blocker use were similar regardless of how multimorbidity burden was characterized. CONCLUSIONS: Simple counts of chronic conditions performed similarly to a weighted multimorbidity score in predicting outcomes using real-world data to examine clinical outcomes associated with ß-blocker therapy in HF. Our findings challenge conventional wisdom that more complex measures of multimorbidity are always necessary to characterize patients in observational studies examining therapy-associated outcomes.

RESUMO

The aim of this study is to analyse the changing patterns in the transmission of COVID-19 in relation to changes in Vietnamese governmental policies, based on epidemiological data and policy actions in a large Vietnamese province, Bac Ninh, in 2021. Data on confirmed cases from January to December 2021 were collected, together with policy documents. There were three distinct periods of the COVID-19 pandemic in Bac Ninh province during 2021. During the first period, referred to as the 'Zero-COVID' period (01/04-07/04/2021), there was a low population vaccination rate, with less than 25% of the population receiving its first vaccine dose. Measures implemented during this period focused on domestic movement restrictions, mask mandates, and screening efforts to control the spread of the virus. The subsequent period, referred to as the 'Transition' period (07/05-10/22/2021), witnessed a significant increase in population vaccination coverage, with 80% of the population receiving their first vaccine dose. During this period, several days passed without any reported COVID-19 cases in the community. The local government implemented measures to manage domestic actions and reduce the time spent in quarantine, and encouraged home quarantining for the close contacts of cases with COVID-19. Finally, the 'New-normal' stage (10/23-12/31/2021), during which the population vaccination coverage with a second vaccine dose increased to 70%, and most of the mandates for the prevention and control of COVID-19 were reduced. In conclusion, this study highlights the importance of governmental policies in managing and controlling the transmission of COVID-19 and provides insights for developing realistic and context-specific strategies in similar settings.

RESUMO

The LEAFY COTYLEDON1 (LEC1) transcription factor is a central regulator of seed development, because it controls diverse biological programs during seed development, such as embryo morphogenesis, photosynthesis, and seed maturation. To understand how LEC1 regulates different gene sets during development, we explored the possibility that LEC1 acts in combination with other transcription factors. We identified and compared genes that are directly transcriptionally regulated by ABA-RESPONSIVE ELEMENT BINDING PROTEIN3 (AREB3), BASIC LEUCINE ZIPPER67 (bZIP67), and ABA INSENSITIVE3 (ABI3) with those regulated by LEC1. We showed that LEC1 operates with specific sets of transcription factors to regulate different gene sets and, therefore, distinct developmental processes. Thus, LEC1 controls diverse processes through its combinatorial interactions with other transcription factors. DNA binding sites for the transcription factors are closely clustered in genomic regions upstream of target genes, defining cis-regulatory modules that are enriched for DNA sequence motifs that resemble sequences known to be bound by these transcription factors. Moreover, cis-regulatory modules for genes regulated by distinct transcription factor combinations are enriched for different sets of DNA motifs. Expression assays with embryo cells indicate that the enriched DNA motifs are functional cis elements that regulate transcription. Together, the results suggest that combinatorial interactions between LEC1 and other transcription factors are mediated by cis-regulatory modules containing clustered cis elements and by physical interactions that are documented to occur between the transcription factors.

RESUMO

PURPOSE: To review the advances in the surgical techniques of orbital decompression. METHODS: A literature review of orbital decompression surgery and experience-based consideration of bony areas for decompression. RESULTS: In the 100-year-plus span of orbital decompression literature, multiple incisions and multiple bone and fat removal strategies have been described. In general, bone removal has been conceptualized as consisting of 4 walls of the orbit. However, the orbital bony anatomy is more subtle than a simple box, and considering 6 areas of potential bony removal allows a more nuanced paradigm for clinical decision-making and for understanding various technique descriptions. Historical and current techniques, and surgical planning and decision-making, are described from the perspective of a 6 area paradigm. Potential complications are reviewed. CONCLUSION: A conceptual framework for orbital decompression focusing on 6 potential areas of bone removal provides a nuanced and flexible paradigm for understanding and describing surgical techniques, and for designing individualized surgery. Orbital decompression surgery should be customized to the patient's anatomy and symptoms.

RESUMO

A 28-year-old female with congenital left-sided ptosis presented after 3 prior surgeries elsewhere. Although centrally her margin to reflex distance1 was 3 mm, persistent ptosis was noted laterally. In an effort to improve the symmetry of her eyelid contour, a lateral tarsectomy was performed. As the authors worried this might worsen her dryness, the decision was made to bank the excised tarso-conjunctival tissue in case additional revision surgery is required at a later date. To accomplish this, a conjunctival incision was created at the inferior tarsal margin in the ipsilateral lower lateral eyelid and the excised upper eyelid tarso-conjunctival tissue was secured in this pocket. Four months postoperatively, the banked tissue appeared healthy and the upper eyelid contour was improved. This technique may be most helpful in multi-operated situations, where the chance of future revision is not insignificant.

RESUMO

PURPOSE: The purpose of this study was to compare the efficacy of 3 resection algorithms in the management of patients with asymmetric ptosis. METHODS: Patients undergoing bilateral Muller's muscle-conjunctival resection (MMCR) were identified. Standardized preoperative clinical photographs were examined and margin reflex distance 1 (MRD1) was measured using ImageJ. Patients presenting with ≥1 mm of asymmetry in MRD1 were included. Three groups were identified: variable (4:1 ratio, with the lower side receiving a greater resection), fixed (7 mm resection bilaterally), and tarsectomy (7 mm bilaterally + 1 mm of tarsus resected on the lower preoperative side). Postoperative MRD1 was measured from photographs obtained 3 months after surgery. The primary outcome was postoperative asymmetry. RESULTS: A total of 95 patients with a mean age of 71.0 ± 11.0 years were included. There was no significant difference in age ( p = 0.277) or length of follow-up ( p = 0.782) between the groups. Although the fixed tarsectomy group had significantly greater preoperative asymmetry ( p = 0.001), there was no significant difference in postoperative asymmetry ( p = 0.166). On multivariate analysis, preoperative asymmetry was the only significant predictor of postoperative asymmetry ( p < 0.001). Specifically, the surgical group was not a predictor of the primary outcome ( p = 0.723). CONCLUSIONS: Resection amount and technique did not predict postoperative outcomes in cases of asymmetric ptosis. This may support the hypothesis that changes in eyelid position and symmetry following MMCR is due to a dynamic system, rather than as a result of purely mechanical forces.

RESUMO

Orbital involvement in acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) is well-described in children but is uncommon in adults. This series reports 2 adult patients with orbital leukemic involvement and summarizes the existing literature. A 37-year-old male with recently diagnosed AML underwent induction therapy and subsequently developed a tan-pink colored sub-conjunctival lesion in the left eye. Incisional biopsy confirmed AML. A 35-year-old male with history of ALL presented with left-sided orbital mass. Fine needle aspiration biopsy confirmed ALL. Literature review of adult-onset orbital leukemia yielded 29 cases of AML and 3 cases of ALL. Orbital involvement of acute adult-onset leukemia tends to be unilateral, presents in the extraconal space and can occur at any point during systemic leukemic disease. Chemotherapy is the mainstay of treatment, often in combination with radiation and/or hematopoietic stem cell transplant.

RESUMO

PURPOSE: To compare outcomes of patients with thyroid eye disease treated with teprotumumab or orbital decompression, or both in sequence. METHODS: Patients with thyroid eye disease and treated with decompression, teprotumumab, or both were included. Four groups were defined: decompression only, teprotumumab only, teprotumumab first with decompression later, and decompression first with teprotumumab later. The primary outcome was change in exophthalmometry. Secondary outcomes included change in extraocular muscle motility, strabismus, diplopia, and side effects. RESULTS: One hundred and thirty-nine patients were included. The mean duration for early follow-up was 1.2 months for both decompression and teprotumumab groups. The mean late follow-up was 14.4 and 8.2 months for the decompression and teprotumumab groups respectively. Mean change in exophthalmometry was significantly greater for the decompression group (3.5 mm) compared with teprotumumab (2.0 mm) at late follow-up. Improvement in total extraocular muscle restriction was significantly greater in the teprotumumab group (14.7 degrees) than in the decompression group (2.6 degrees). The teprotumumab group had a significantly higher percentage of patients with diplopia score >1 at baseline and late follow-up (p < 0.01) compared with the decompression group. Additional treatment with teprotumumab or decompression when previously treated with the opposite had similar proptosis reduction effect as that therapy alone. CONCLUSIONS: Surgical decompression has a greater proptosis reduction effect than teprotumumab, whereas teprotumumab better improves extraocular muscle motility. The addition of teprotumumab or decompression to a previous course of the opposite adds a similar effect to the supplemental treatment alone.

RESUMO

BACKGROUND: As patient prices for many medications have risen steeply in the United States, patients may engage in cost-reducing behaviors (CRBs) such as asking for generic medications or purchasing medication from the Internet. OBJECTIVE: The objective of this study is to describe patterns of CRB, cost-related medication nonadherence, and spending less on basic needs to afford medications among older adults with atrial fibrillation (AF) and examine participant characteristics associated with CRB. METHODS: Data were from a prospective cohort study of older adults at least 65 years with AF and a high stroke risk (CHA2DS2VASc ≥ 2). CRB, cost-related medication nonadherence, and spending less on basic needs to afford medications were evaluated using validated measures. Chi-square and t tests were used to evaluate differences in characteristics across CRB, and statistically significant characteristics (P < 0.05) were entered into a multivariable logistic regression to examine factors associated with CRB. RESULTS: Among participants (N = 1224; mean age 76 years; 49% female), 69% reported engaging in CRB, 4% reported cost-related medication nonadherence, and 6% reported spending less on basic needs. Participants who were cognitively impaired (adjusted odds ratio 0.69 [95% CI 0.52-0.91]) and those who did not identify as non-Hispanic white (0.66 [0.46-0.95]) were less likely to engage in CRB. Participants who were married (1.88 [1.30-2.72]), had a household income of $20,000-$49,999 (1.52 [1.02-2.27]), had Medicare insurance (1.38 [1.04-1.83]), and had 4-6 comorbidities (1.43 [1.01-2.01]) had significantly higher odds of engaging in CRB. CONCLUSION: Although CRBs were common among older adults with AF, few reported cost-related medication nonadherence and spending less on basic needs. Patients with cognitive impairment may benefit from pharmacist intervention to provide support in CRB and patient assistance programs.

RESUMO

PURPOSE: One of the most devastating complications of facial filler injection is sudden ischemic blindness. However, its mechanisms and predisposing factors are poorly understood. The purpose of this study was to investigate the prevalence of external carotid artery (ECA) to ophthalmic artery (OA) anterograde flow in patients with internal carotid artery (ICA) stenosis and in a control population without carotid disease. METHODS: In this cross-sectional cohort study, two groups of patients who underwent catheter cerebral angiography over a 5-year period were identified: patients with symptomatic ICA stenosis and a control group of patients with refractory epistaxis undergoing embolization. Angiograms were reviewed by an interventional neuroradiologist. The primary outcome measure was the presence of ECA to OA flow, defined as choroidal blush before filling of the circle of Willis. Secondary outcome measures included the percentage and location of ICA stenosis and ECA anastomotic branches involved. RESULTS: The study included 149 patients with ICA stenosis and 69 control patients. ECA to OA flow was more prevalent in patients with ICA stenosis (34.9%) compared to controls (2.9%) (p < .001). Logistic regression demonstrated that for each 10% increase in ICA stenosis over 70%, there was 2.8 times increased risk of ECA to OA flow (p < .001). CONCLUSIONS: ECA to ICA anterograde flow can be demonstrated in approximately 3% of control patients and in over 1/3 of patients with symptomatic carotid stenosis. This provides a plausible pathway for small filler particles to pass with blood flow from the facial to the ophthalmic circulation.

RESUMO

The measurement of values of apparent equilibrium constants K' for enzyme-catalyzed reactions involve a substantial number of critical details, neglect of which could lead to systematic errors. Here, interferences, impurities in the substances used, and failure to achieve equilibrium are matters of substantial consequence. Careful reporting of results is of great importance if the results are to have archival value. Thus, attention must be paid to the identification of the substances, specification of the reaction(s), the conditions of reaction, the definition of the equilibrium constant(s) and standard states, the use of standard nomenclature, symbols, and units, and uncertainties. This document contains a general discussion of various aspects of these equilibrium measurements as well as STRENDA (Standards for Reporting Enzymology Data) recommendations regarding the measurements and the reporting of results.

RESUMO

BACKGROUND: In older patients with atrial fibrillation (AF), physical, cognitive, and psychosocial limitations are prevalent. The prognostic value of these conditions for major bleeding is unclear. OBJECTIVE: To determine whether geriatric conditions are prospectively associated with major bleeding in older patients with AF on anticoagulation. DESIGN: Multicenter cohort study with 2-year follow-up from 2016 to 2020 in Massachusetts and Georgia from cardiology, electrophysiology, and primary care clinics. PARTICIPANTS: Diagnosed with AF, age 65 years or older, CHA2DS2-VASc score of 2 or higher, and taking oral anticoagulant (n=1,064). A total of 6507 individuals were screened. MAIN MEASURES: A six-component geriatric assessment of frailty, cognitive function, social support, depressive symptoms, vision, and hearing. Main outcome was major bleeding adjudicated by a physician panel. KEY RESULTS: At baseline, participants were, on average, 75.5 years old and 49% were women. Mean CHA2DS2-VASc score was 4.5 and the mean HAS-BLED score was 3.3. During 2.0 (± 0.4) years of follow-up, 95 (8.9%) participants developed an episode of major bleeding. After adjusting for key covariates and accounting for competing risk from death, cognitive impairment (hazard ratio [HR] 1.62, 95% confidence interval [CI]: 1.02-2.56) and frailty (HR 2.77, 95% CI 1.38-5.58) were significantly associated with the development of major bleeding. CONCLUSIONS: In older patients with AF taking anticoagulants, cognitive impairment and frailty were independently associated with major bleeding.

RESUMO

PURPOSE: Spheno-orbital meningiomas are rare tumors, accounting for up to 9% of all intracranial meningiomas. Patients commonly present with proptosis, and visual deficits. These slow growing tumors are hard to resect due to extension into several anatomical compartments, resulting in recurrence rates as high as 35-50%. Although open surgical approaches have been historically used for resection, a handful of endoscopic approaches have been reported in recent years. We aimed to review the literature and describe a case of spheno-orbital meningioma with severe vision loss which was resected with an endoscopic endonasal approach achieving complete resolution of visual symptoms. METHODS: A systematic review of literature was conducted in accordance with the PRISMA guidelines. PubMed, Cochrane, and Web of Science databases were queried for spheno-orbital meningiomas resected via an endoscopic endonasal approach. Furthermore, the presentation, surgical management, and post-operative outcomes of a 53-year-old female with a recurrent spheno-orbital meningioma are described. RESULTS: The search yielded 26 articles, of which 8 were included, yielding 19 cases. Average age at presentation was 60.5 years (range: 44-82), and 68.4% of patients were female. More than half of the cases achieved subtotal resection. Common complications associated with endoscopic endonasal surgery included CN V2 or CN V2/V3 hypoesthesia. Following surgical intervention, visual acuity and visual field remained stable or improved in the majority of the patients. CONCLUSION: Endoscopic approaches are slowly gaining momentum for treatment of spheno-orbital meningiomas. Further studies on the clinical benefits of this approach on patient outcomes and post-operative complications is warranted.

RESUMO

PURPOSE: Treatment for orbital venolymphatic malformations (VLMs) commonly includes 3 major options: sclerotherapy, surgery, and embolization followed by surgical excision. Each has certain advantages, although it is not clear whether all are effective. The authors characterize the clinical course for a series of patients with distensible orbital venous-dominant VLM treated with sclerotherapy and/or embolization with excision. METHODS: In this cross-sectional cohort study, patients affected by distensible orbital venous-dominant VLM presenting to the orbital and ophthalmic plastic surgery service from 2014 to 2020 were identified. Patients were included if they presented with a moderate-flow, distensible venous-dominant malformation associated with Valsalva-related symptoms (e.g., pain, proptosis, and diplopia). RESULTS: Six cases were treated with sclerotherapy. Four underwent multiple treatments, with a mean ± SD of 3.5 ± 2.3 (range 1-7). All patients in this group failed to improve or experienced recurrence of symptoms after sclerotherapy. Twelve cases were treated with embolization and excision. Resolution of symptoms in all 12 cases was noted and maintained for a mean of 3.4 ± 2.1 years. There have been no cases of recurrence. Patients treated with sclerotherapy were more likely to experience recurrence of symptoms compared to those treated with embolization and excision (p < 0.001). CONCLUSIONS: Treatment of distensible venous-dominant moderate-flow orbital VLM with sclerotherapy may provide temporary improvement in some cases. However, in the medium to long term, recurrence was universal in this series. Embolization with excision appears to provide more definitive management, avoiding recurrence in all cases for a mean follow-up of 3 years.
