Zahavi A, Luckman J, Ben-David GS, Toledano H, Michowiz S, Vardizer Y, Goldenberg-Cohen N. Proptosis due to intraorbital space-occupying lesions in children. Graefes Arch Clin Exp Ophthalmol 2020; 258:2541-2550. [PMID: 32676791 DOI: 10.1007/s00417-020-04840-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Revised: 07/05/2020] [Accepted: 07/10/2020] [Indexed: 10/23/2022] Open
Abstract
PURPOSE To report the 10-year experience of two tertiary medical centers with children presenting with proptosis due to an intraorbital space-occupying lesion. METHODS Patients were identified by file review. Data were collected on demographics, findings on ophthalmologic and imaging evaluations, etiology, treatment, and outcome. RESULTS Nineteen children (7 male) were included. Eleven patients had optic nerve glioma, including 9 with substantially decreased visual acuity. Treatment consisted of chemotherapy alone or with radiation, resection or anti-VEGF agents, MEK inhibitor, or observation only (n = 1). Visual and cosmetic outcomes were poor in all cases. Outcome for arteriovenous malformations was good following corticosteroid treatment (n = 1), but catheterization led to persistent proptosis and fluctuating visual acuity (n = 1). Compound capillary hemangioma (n = 1) was treated with laser and systemic beta blockers with satisfactory results. Rhabdomyosarcoma had a good prognosis in one patient treated with resection and radiation but was fatal in another even after chemotherapy. Juvenile xanthogranuloma, frontal bone osteoma, and localized hypertrophic neuropathy of the supraorbital nerve (n = 1 each) were treated by resection with good visual and cosmetic outcomes. CONCLUSIONS Proptosis accompanied by visual loss is an uncommon presentation in children and suggests an orbital tumor. We found that visual outcome was better when the nerve was not involved by tumor. Optic nerve glioma was the most common cause and failed to respond to various treatments. Catheterization for arteriovenous malformation did not prevent proptosis, and final visual acuity fluctuated. Surgery for rhabdomyosarcoma and xanthogranuloma led to remission with preservation of vision in 2 of 3 cases.

Abstract
Optic nerve diseases arise from many different etiologies including inflammatory, neoplastic, genetic, infectious, ischemic, and idiopathic. Understanding some of the characteristics of the most common optic neuropathies along with therapeutic approaches to these diseases is helpful in designing recommendations for individual patients. Although many optic neuropathies have no specific treatment, some do, and it is those potentially treatable or preventable conditions which need to be recognized in order to help patients regain their sight or develop a better understanding of their own prognosis. In this chapter several diseases are discussed including idiopathic intracranial hypertension, optic neuritis, ischemic optic neuropathies, hereditary optic neuropathies, trauma, and primary tumors of the optic nerve. For each condition there is a presentation of the signs and symptoms of the disease, in some conditions the evaluation and diagnostic criteria are highlighted, and where possible, current therapy or past trials are discussed.

Abstract
Intracranial astrocytomas are relatively uncommon in dogs and optic nerve astrocytomas even more so. This neoplasm should be considered as differential in canine patients with vision loss, retinal detachment, ocular mass, and histopathologic findings of infiltrative fusiform to polygonal glial cells possibly associated with glomeruloid vascular proliferation.

[Optic chiasm glioma in children: Endocrine disorders in 14 cases]. Med Clin (Barc) 2016; 146:446-9. [PMID: 26971985 DOI: 10.1016/j.medcli.2016.01.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2015] [Revised: 12/27/2015] [Accepted: 01/07/2016] [Indexed: 11/22/2022]
Abstract
BACKGROUND AND OBJECTIVES To describe the frequency of endocrine disorders in children with optic chiasm glioma and analyze related factors. PATIENTS AND METHODS Review of medical records by collecting sex, age, history of neurofibromatosis, clinical presentation, treatment of tumour, and presence of endocrine abnormalities. Statistical tests Wilcoxon and Fisher. RESULTS 14 patients (6 female) with age at diagnosis of 0.5 to 7.0 years (mean±standard deviation: 2.97±2.32) and follow-up of 10.64±3.30 years (range 6.0 to 16.0). 12/14 presented endocrinopathy at follow-up: 8 precocious puberty, 5 hypopituitarism, and 5 obesity. The onset of deficits was related to the neuroophthalmological symptoms under the age of five (P=.02)and treatment of the tumour was required.(P=.03). CONCLUSIONS Children with optic chiasm gliomas may present endocrine disorders from the time of diagnosis of the tumor and, in particular as they develop on. The most common of these is precocious puberty. Pituitary deficits are associated with more aggressive tumours (those presenting with neuroophthalmological signs and symptoms before the age of five and requiring treatment).

Abstract
Orbital tumors constitute a group of diverse lesions with a low incidence in the population. Tumors affecting the eye and ocular adnexa may also secondarily invade the orbit. Lack of accumulation of a sufficient number of cases with a specific diagnosis at various orbital centers, the paucity of prospective randomized studies, animal model studies, tissue bank, and genetic studies led to the development of various myths regarding the diagnosis and treatment of orbital lesions in the past. These myths continue to influence the diagnosis and treatment of orbital lesions by orbital specialists. This manuscript discusses some of the more common myths through case summaries and a review of the literature. Detailed genotypic analysis and genetic classification will provide further insight into the pathogenesis of many orbital diseases in the future. This will enable targeted treatments even for diseases with the same histopathologic diagnosis. Phenotypic variability within the same disease will be addressed using targeted treatments.

Abstract
β-catenin is a crucial oncogene that is capable of regulating cancer progression. The aim of the present study was to clarify whether β-catenin was associated with the proliferation and progress of glioma. In order to knockdown the expression of β-catenin in human U251 glioma cells, three pairs of small interfering (si)RNA were designed and synthesized and the most effective siRNA was selected and used for silencing the endogenous β-catenin, which was detected by western blot analysis and reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Proliferation was subsequently detected using a methylthiazolyl-tetrazolium bromide assay and the results demonstrated that knockdown of β-catenin significantly inhibited the proliferation of U251 cells in a time- and dose-dependent manner (P<0.01). Cell apoptosis rate was analyzed using flow cytometry and Annexin V-fluorescein isothiocyanate/propidium iodide staining demonstrated that β-catenin siRNA significantly increased the apoptosis of U251 cells (P<0.01). Furthermore, the results of an in vitro scratch assay demonstrated that β-catenin silencing suppressed the proliferation of U251 cells, as compared with the control group (P<0.01). In vivo, β-catenin expression levels in U251 cells were significantly inhibited (P<0.01) following β-catenin short hairpin (sh)RNA lentiviral-vector transfection, as detected by western blot analysis and RT-qPCR. Tumorigenicity experiments demonstrated that β-catenin inhibition significantly increased the survival rate of nude mice. The results of the present study demonstrated that knockdown of β-catenin expression significantly inhibited the progression of human glioma cancer cells, in vitro and in vivo; thus suggesting that β-catenin silencing may be a novel therapy for the treatment of human glioma.
