A 38-year-old female patient experienced recurrent episodes of neurological deterioration during febrile illness at the age of 7 and 8 months, and 2, 4, and 37 years. Acute symptoms comprised unconsciousness, headache, abnormal ocular movements, flaccid paralysis with areflexia, ataxia, dysphagia, and movement disorders. Each episode of neurological deterioration was followed by partial recovery with residual symptoms of progressive disturbance of visual acuity with optic atrophy and hearing loss, moderate intellectual disability, strabismus, ophthalmoplegia, as well as fluctuating degree of gait ataxia, chorea, tremor, and myoclonus...

A 4-year-old girl presented with acute left visual loss 4 weeks after uneventful chickenpox. She was found to have left necrotising retinitis and profound retinal vasculitis and vitritis. Aqueous humour was PCR positive for varicella-zoster virus. Combined intravenous and intravitreal antiviral treatment led to rapid improvement with settled retinitis, no vascular occlusion and good recovery of vision. Her recent coinfection with Epstein-Barr virus may have acted to provoke the retinitis.

BACKGROUND: A variety of cast options are available for the non-surgical treatment of distal radius fractures (DRF) in adults. However, the literature is inconclusive regarding the need to immobilize the elbow joint after reduction in order to prevent rotation of the forearm in order to maintain the reduction of DRF. This study aimed to evaluate the best method of immobilization between above-elbow (AE) and below-elbow (BE) cast groups at the end of six-month follow-up. METHODS: This is a randomized clinical trial with parallel groups and a blinded evaluator...

BACKGROUND: Socio-emotional development is the expression and management of emotions, which in non-human primates can be examined using responses toward increasing levels of threat. Damage to the limbic system alters socio-emotional development in primates. Thus, neuronal and glial cell loss caused by exposure to general anaesthesia early in infancy might also impact socio-emotional development. We recently reported that repeated sevoflurane exposure in the first month of life alters emotional behaviours at 6 months of age and impairs visual recognition memory after the first year of life in rhesus monkeys...

A 49-year-old previously healthy woman presented with acute painless visual loss in the right eye, a right relative afferent pupillary defect, and a normal fundus examination. She was diagnosed with retrobulbar "optic neuritis" and given a course of intravenous steroids. Despite treatment, however, she continued to lose vision and serial visual field testing confirmed a junctional scotoma in the fellow eye. Cranial magnetic resonance imaging (MRI) showed a mass at the junction between the right optic nerve and the anterior aspect of the chiasm and a right frontal lesion that proved to be multicentric glioblastoma multiforme...

Cytomegalovirus (CMV) retinitis is one of the rare but debilitating presentations of the CMV infection in children with leukemia. Herein, we report a 12-year-old boy with acute myeloid leukemia complicated by rapid progressive visual loss during relapse of leukemia. The definite diagnosis of CMV retinitis was made after vitreous aspiration. Despite prompt treatment and ophthalmologic intervention, he died because of AML relapse. Viral infections, especially cytomegalovirus infection, may present with vague clinical pictures during any time of chemotherapy, which may not be easily distinguishable from bacterial or fungal retinitis and also chemotherapy-induced retinopathies...

BACKGROUND: We present a case of orbital compartment syndrome (OCS) leading to monocular irreversible blindness following a pterional craniotomy for clipping of an anterior communicating artery (ACoA) aneurysm. OCS is an uncommon but vision-threatening entity requiring urgent decompression to reduce the risk of permanent visual loss. Iatrogenic orbital roof defects are a common finding following pterional craniotomies. However, complications related to these defects are rarely reported...

Craniopharyngiomas are benign tumors and account for approximately 5.6-13% of all intracranial tumors in children. Diagnosis of pediatric craniopharyngioma is often delayed until the tumor becomes relatively large and manifests severe visual and/or endocrine disturbance. Endoscopic endonasal approaches have recently been introduced to surgery for craniopharyngioma. These techniques, however, have rarely been utilized in patients affected with craniopharyngioma as young as 1 year old. This report documents a 12-month-old male infant with sellar craniopharyngioma who presented with acute total vision loss...

BACKGROUND: Intraarticular steroid injections are a common first-line therapy for severe osteoarthritis, which affects an estimated 27 million people in the United States. Although topical, oral, intranasal, and inhalational steroids are known to increase intraocular pressure in some patients, the effect of intraarticular steroid injections on intraocular pressure has not been investigated, to the best of our knowledge. If elevated intraocular pressure is sustained for long periods of time or is of sufficient magnitude acutely, permanent loss of the visual field can occur...

Optic neuritis is an acute inflammatory demyelinating disorder of the optic nerve (ON) and is an initial symptom of multiple sclerosis (MS). Optic neuritis is characterized by ON degeneration and retinal ganglion cell (RGC) loss that contributes to permanent visual disability and lacks a reliable treatment. Here, we used the experimental autoimmune encephalomyelitis (EAE) mouse model of MS, a well-established model also for optic neuritis. In this model, C57BL6 mice, intraperitoneally injected with a fragment of the myelin oligodendrocyte glycoprotein (MOG), were found to develop inflammation, Müller cell gliosis, and infiltration of macrophages with increased production of oncomodulin (OCM), a calcium binding protein that acts as an atypical trophic factor for neurons enabling RGC axon regeneration...

BACKGROUND: Inotuzumab ozogamicin (InO), an anti-CD22 antibody-calicheamicin conjugate, demonstrated superior clinical activity versus standard-of-care (SOC) chemotherapies for relapsed/refractory B-cell acute lymphoblastic leukemia in the phase 3 randomized controlled INO-VATE trial. The authors assessed patient-reported outcomes (PROs) from that study. METHODS: Patients were randomized to receive either InO (1.8 mg/m2 per cycle for ≤6 cycles) or SOC (fludarabine/cytarabine [ara-C]/granulocyte colony-stimulating factor, or ara-C plus mitoxantrone, or high-dose ara-C for ≤4 cycles) and completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and the EuroQoL 5 Dimensions Questionnaires at baseline, on day 1 of each cycle, and at the end of treatment...
