OBJECTIVES: Graves' ophthalmopathy occurs in 50% of Graves' disease cases. Treatment is based on smoking cessation, and control of the euthyroidism and ocular repercussions associated with the disease. The active orbital forms are treated with glucocorticoids. Non-validated therapies have also been recently tested. Rituximab has been effectively used several times to treat corticosteroid-resistant Graves' ophthalmopathy associated with an optic neuropathy, but its use could be proposed only in inflammatory ophthalmopathies after failure of the corticosteroids...

Tumid lupus is an uncommon variant of lupus erythematosus. Patients present with subcutaneous lesions. Ophthalmic literature reports disease manifestation as orbital inflammation. Autoimmune serology is often negative. Without a high index of suspicion, the diagnosis is easily overlooked delaying treatment. Tumid lupus is not significantly discussed in the Otolaryngologic literature. Here we present a Case Report of a male who initially presented to Ophthalmology with unilateral orbital complaint of eyelid puffiness...

Sinonasal infections and nasal polyps can be taken as 2 components of a disease. Polyps due to chronic inflammations of nasal cavity and sinuses are not rare. They may present with various clinical signs and symptoms, while the secondary complications may cause serious problems. They are most commonly treated medically, although surgery is the therapy of choice in some conditions. The complications can be listed as mucocele formation, orbital inflammation, intracranial extension by erosion of the boney structures...

The success of rituximab for the treatment of active Graves' orbitopathy (GO) suggests that B cells play a critical role in intraorbital inflammation. B cell activating factor (BAFF) and its homolog a proliferation-inducing ligand (APRIL) are critical for B cell survival. However, the contribution of BAFF/APRIL to GO remains unclear. We sought to determine the role of BAFF/APRIL in the orbits of GO, and found that BAFF was markedly upregulated, while APRIL was not. Additionally, cultured GO orbital fibroblasts (GO-OFs)(2) expressing BAFF were induced to produce a large amount of BAFF...

Cluster headache is a relatively rare headache disorder, typically characterized by multiple daily, short-lasting attacks of excruciating, unilateral (peri-)orbital or temporal pain associated with autonomic symptoms and restlessness. To better understand the pathophysiology of cluster headache, we used RNA sequencing to identify differentially expressed genes and pathways in whole blood of patients with episodic (n = 19) or chronic (n = 20) cluster headache in comparison with headache-free controls (n = 20)...

Viral myocarditis is the inflammation caused by myocardial virus infection, and the coxsackievirus group B3 virus (CVB3) is the most common pathogen. An efficient therapeutic agent against viral myocarditis is currently unavailable. IL-33, a new member of the IL-1 cytokine superfamily, exhibits potential immunotherapeutic effect against inflammatory and autoimmune diseases. However, the functional role of IL-33 in viral myocarditis has not been investigated. To examine the therapeutic role of IL-33 in viral myocarditis, an IL-33 overexpression plasmid (pDisplay-IL-33) and IL-33 knockdown plasmid (pLL3...

A 55-year-old woman developed no light perception vision in her right eye 5 days after an injection of polylactic acid cosmetic filler into her right forehead. Diffuse corneal edema and anterior chamber inflammation prohibited any view to the posterior segment to identify the cause of her profound vision loss. MRI of the orbits with diffusion-weighted imaging showed hyperintensity of the right optic nerve with signal reduction on apparent diffusion coefficient mapping, consistent with ischemia. Our patient also was found to have acute infarctions in the distribution of the right anterior cerebral artery on MRI of the brain despite having no permanent focal neurologic deficits aside from vision loss...

The Th1- and Treg cell-related immune responses play key roles in the modulation of Th2 cell-related allergic disorders. The aim was to evaluate the effects of CPG, MPLA, and BCG on the number of Th1-, Th2-, and Treg cell-related parameters in an animal model of asthma. BALB/c mice were divided into five groups and immunized subcutaneously (SC) on days 1, 15, and 22 with allergen Derp2. Three groups of mice were pretreated SC on days 0, 14, and 21 with CPG, CPG + MPLA, or CPG + BCG. All mice were then challenged intranasally with Derp2 on days 28-37...

An 8-year-old boy initially presented with an orbitopalpebral mass diagnosed clinically and radiologically as a low-flow diffuse venous lymphatic malformation involving the left upper eyelid and orbit. Over 8 months of follow up, he had 2 acute episodes of severe orbital inflammation that warranted hospitalization and treatment with intravenous antibiotic, steroids and surgical debulking. After a third surgical excision, the lesion remained clinically stable.

A 6-month-old boy presented with a unilateral motility deficit of the right eye in all fields of gaze. Neuroimaging revealed unilateral enlargement of the medial, lateral, and inferior rectus muscles with sparing of the tendons. An evaluation for thyroid eye disease, idiopathic orbital inflammation, myositis, inflammatory and neoplastic infiltration of the muscle, vascular anomalies, and metastatic neuroblastoma was unrevealing. Biopsy of the muscle revealed normal architecture with an absence of inflammation, infiltration, or fibrosis...

Pheochromocytoma multisystem crisis is the most severe presentation of pheochromocytoma. We report on a 68-year-old survivor of pheochromocytoma multisystem crisis, whose clinical course was triggered inadvertently by a short innocuous course of oral dexamethasone to suppress inflammation and swelling after a left orbital floor fracture repair. He presented first with severe epigastric pain and headache, and subsequently experienced insults to neurological, cardiac, respiratory, hepatobiliary, renal, and immune system in his prolonged intensive care unit stay...

Orbital biopsy of nonspecific orbital inflammation, commonly referred to as "orbital pseudotumor," typically shows a combination of polyclonal lymphocytes, plasmocytes, leukocytes, macrophages, and variable degrees of collagen deposition. Herein, we report a patient with a positive history of mucocutaneous leishmaniasis who presented with an orbital mass with a histological profile of idiopathic orbital inflammation. Immunohistochemical and molecular analysis of the orbital specimens demonstrated that the orbital inflammation was associated with the presence of antigens of Leishmania braziliensis and DNA from the parasite...

A 68-year-old immunocompromised man with rhino-orbital-cerebral mucormycosis was treated with retrobulbar injections of amphotericin B deoxycholate in conjunction with intravenous antifungals and endoscopic sinus debridement. Transient episodes of orbital inflammation were noted after retrobulbar injections, but progression of orbital infection was halted and visual acuity restored with eventual hospital discharge. To the authors' knowledge, clearance of orbital mucormycosis with retrobulbar amphotericin B injections has not been previously reported...

A dog presented with a retrobulbar mass, diagnosed histopathologically as malignant spindle cell neoplasia. Emergence of analogous findings in the contralateral orbit prompted extended immunohistochemistry of the original mass and reassignment to idiopathic sclerosing orbital inflammation. Early incisional biopsy with extended immunohistochemical analysis should be considered for canine orbital tumors.

BACKGROUND: Sleep is integral to biologic function, and sleep disruption can result in both physiological and psychologic dysfunction including cognitive decline. Surgery activates the innate immune system, inducing neuroinflammatory changes that interfere with cognition. Because surgical patients with sleep disorders have an increased likelihood of exhibiting postoperative delirium, an acute form of cognitive decline, we investigated the contribution of perioperative sleep fragmentation (SF) to the neuroinflammatory and cognitive responses of surgery...
