Rationale: Myasthenia gravis (MG) is an uncommon autoimmune disease mediated by antibodies that attack the postsynaptic acetylcholine receptors (AchRs) at the neuromuscular junction, causing fluctuating muscle weakness, aggravated with use, and relieved with rest.
Patient Concerns: A 32-year-old woman with a diagnosis of MG based on clinical findings, eletroneuromyography, and brain magnetic resonance imaging (MRI) was admitted to our hospital with dysphagia, dysphonia, diplopia, and intense weakness, associated with a 2-day viral gastroenteritis.
Diagnoses: Physical examination revealed globally reduced deep tendon reflexes, and tetraparesis, with muscle strength grade 4 in the left limbs and grade 2 in the right limbs. Read More

Importance: The peeling of an epiretinal membrane (ERM) is commonly performed for poor visual acuity and/or metamorphopsia, but to our knowledge, its influence on central-peripheral rivalry (CPR)-type diplopia has not been rigorously studied.
Objective: To evaluate the occurrence of either resolution or new-onset CPR-type diplopia in patients undergoing ERM peeling.
Design, Setting, And Participants: This prospective cohort study was conducted from July 2014 to April 2018 at a tertiary referral medical center and included 33 adults with ERM who were undergoing peeling surgery with planned preoperative to postoperative analysis. Read More

Background: Metastases to the orbit occur rarely in midgut neuroendocrine tumor (NET) patients with only 20 cases reported to date. Patients typically present with bilateral involvement of the recti muscles and experience symptoms such as diplopia, proptosis, and decreased vision. Although orbital MRI remains the gold standard for imaging orbital disease, many orbital lesions are now detected on somatostatin-receptor (SSTR) based imaging such as 68Ga-DOTATATE PET-CT. Read More

The reconstruction of orbital-maxillary-zygomatic complex (OMZC) on patients suffering from trauma and space-occupying lesions is challenging due to the irregularity of craniomaxillofacial bones. To overcome the challenge in precise OMZC reconstruction, individual three-dimensional (3D) disease models and mirror-imaged 3D reconstruction models were printed on the basis of the computer tomography. Preoperative planning by rehearsing surgical procedures was made on the 3D disease models and the scaffolds including titanium and absorbable meshes or plates were anatomically premolded using the mirror-imaged 3D models as guide.

The combined transpetrosal approach enables wide exposure around the petroclival region by lifting of the middle fossa dura and cutting of the tentorium. However, interruption of the venous drainage on the middle skull base during the transpetrosal approach has been reported to lead to temporal lobe damage.(1,2) This video (Video 1) demonstrates a microsurgical technique for the preservation of various venous drainage in the middle fossa, including the sphenobasal and sphenopetrosal veins, during the combined transpetrosal approach for treatment of a petroclival meningioma.

Graves' orbitopathy (GO) and pre-tibial mixedema (PTM) are autoimmune manifestation sharing the same etiology and histopathology, a chronic course and a frustrating treatment. Current management include topical and systemic corticosteroid as first line therapy, whereas cyclosporine, surgery and orbital radiotherapy are indicated for severe GO with variable results and mostly temporary remissions. In particular, keratopath and photophobia, due to exophthalmos and eyelid retraction, impaired eye mobility and diplopia due to the compression of optic nerve and extra-ocular muscles are usually minimally modified, as well as leg plaques/nodules and lymphoedema.

Ann Plast Surg 2019 Jan;82(1S Suppl 1):S77-S85
Background And Purpose: Extensive orbital floor and medial wall fractures compared with isolated orbital wall fractures are more likely to require surgical correction because of a higher possibility of complications like diplopia, enophthalmos, or numbness. The unique and complex contours of the orbital anatomy limit the intraoperative view of the intraorbital anatomy, and complex orbital fractures involving the buttress of the transition zone area all make orbital reconstruction surgery more challenging. The aim of this study was to describe our experience with surgical approaches using navigation- and endoscope-assisted guidance for extensive orbital floor and medial wall fracture reconstruction.

Background: The ancient Greek term "apoplexy" as is repeatedly mentioned by the Hippocratic School of Medicine, included a cluster of diseases, mainly those concerning the central nervous system.

Objective: While in "Corpus Hippocraticum" the definition of the stroke was rather ambiguous; our study aims to unveil those fragments referring to it, in order to compose the Hippocratic theory of what it stood for "Acute Brain Suffering" (Greek: Οξείες Οδύνες του Εγκεφάλου) during the Classical era of ancient Greece.
