Optic neuritis presents as an acute or subacute inflammatory episode. Objective: Describe the clinical-epidemiological characteristics in 7 cases with unilateral optic neuritis and evaluate the therapeutic results obtained. Material and method: A series of cases with a diagnosis of unilateral optic neuritis who attended the Neurophthalmology consultation at the Hermanos Ameijeiras Hospital in Havana, Cuba, from August 6 to November 16, 2018, from Havana and Matanzas, were studied. An unusual increase in the incidence of NO was recorded in the period analyzed. Results: An unusual increase in the incidence of unilateral optic neuritis was recorded. The average age was 33.5 years. All reported unilateral painless visual loss. Four patients reported general signs and symptoms suggestive of having suffered a respiratory disease of viral origin, between 7 and 15 days before optic neuritis. In the examination carried out, great impairment of visual acuity (≤0.05) and colors (0/21) was found. The centro-caecal scotoma was the most frequent campimetric defect. Optical Coherence Tomography (OCT) in the affected eye showed increased neuroretinal thickness, decreased nerve fiber layer, and ganglion cell damage. Treatment was with intravenous methylprednisolone and B vitamins. Conclusions: An unusual increase in patients with unilateral optic neuritis was observed. The OCT revealed damage to the structures at the level of the retina and the optic nerve. The therapeutic effectiveness was conditioned by the time of evolution of the neuritis.

Scorpion Stings

Introduction. Scorpion stings occur mainly in spring and summer, with an estimate of 1.2 million cases per year worldwide. About 300,000 poisonings occur within a year, primarily affecting children and adults older than 65 years. In 2019, Guanajuato (Mexico) ranked third in poisoning by scorpion sting with a total of 43,913 cases. The intoxication grades are three where the signs and symptoms are varied. There are two types of antivenom in the Mexican market, and we use Alacramyn® in our case. Case presentation. A 70-year-old female —with grade 1 scorpion sting poisoning, 30 minutes of evolution, with type 2 diabetes and high blood pressure— received two vials of antivenom according to current regulations. She presented transient vagal reaction and subsequent transient pain in the cervical region that radiates to the sacral region. At discharge, there are no data compatible with scorpion sting poisoning. Conclusions. Transient pain in the cervical region to the sacral region may be secondary to an anxiety crisis, hypersensitivity to IgG, or secondary reaction to administration in less time than recommended by the provider. The benefit was greater than the reactions that occurred.

Abstract Background Manifestations of intractable hyponatremia and hypokalemia in autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy have been rarely reported. Case presentation A 75-year-old male patient presented as the case of syndrome of inappropriate antidiuretic hormone secretion (SIADH) and intractable hypokalemia, showed fever, fatigue, and mental disorders. Signs and symptoms of meningoencephalitis, ataxia, and cognitive abnormalities. Magnetic resonance imaging (MRI) revealed multiple white matter lesions of the central nervous system. He had GFAP-IgG in the cerebrospinal fluid (CSF). After treatment with corticosteroids, his symptoms were alleviated gradually, and the level of electrolytes was normal. However, head contrast-enhanced MRI + susceptibility-weighted imaging (SWI) showed a wide afflicted region, and the serum GFAP-IgG turned positive. Considering the relapse of the disease, ha was treated with immunoglobulin and mycophenolate mofetil (MMF) to stabilize his condition. Conclusion This case showed a rare disease with uncommon manifestations, suggesting that careful examination and timely diagnosis are essential for disease management and satisfactory prognosis.

Abstract Background A hip joint ganglion is a rare cause of lower-extremity swelling. Case presentation We report a case of a Japanese patient with ganglion of the hip with compression of the external iliac/femoral vein that produced signs and symptoms mimicking those of deep vein thrombosis. Conclusions Needle aspiration of the ganglion was performed, and swelling of the lower extremity promptly decreased. At 7.5 years after aspiration, there was no recurrence of swelling of the leg. Although the recurrence rate for ganglions after needle aspiration is high, it is worthwhile trying aspiration first.

Introduction Optic neuritis causes retinal nerve fiber layer damage, which can be quantified with optical coherence tomography. Optical coherence tomography may be used to track nerve fiber layer changes and to establish a time-dependent relationship between retinal nerve fiber layer thickness and visual function after optic neuritis. Methods This prospective case series included 78 patients with optic neuritis, who underwent optical coherence tomography and visual testing over a mean period of 28 months. The main outcome measures included comparing inter-eye differences in retinal nerve fiber layer thickness between clinically affected and non-affected eyes over time; establishing when RNFL thinning stabilized after optic neuritis; and correlating retinal nerve fiber layer thickness and visual function. Results The earliest significant inter-eye differences manifested 2-months after optic neuritis, in the temporal retinal nerve fiber layer. Inter-eye comparisons revealed significant retinal nerve fiber layer thinning in clinically affected eyes, which persisted for greater than 24 months. Retinal nerve fiber thinning manifested within 6 months and then stabilized from 7 to 12 months after optic neuritis. Regression analyses demonstrated a threshold of nerve fiber layer thickness (75μm), which predicted visual recovery after optic neuritis. Conclusions Retinal nerve fiber layer changes may be tracked and correlated with visual function within 12 months of an optic neuritis event.

Introduction: Intracranial dermoid cysts are rare, congenital and, benign lesions. The etiology of these lesions is related to an embryonic defect during neurulation. Case presentation: The present study describes a case of a 3-year-old girl with a giant cerebellar dermoid cyst, which initially manifested as hydrocephalus. Discussion: We discuss its epidemiological characteristics as well as diagnostic and therapeutic management. The combination of high clinical suspicion, anamnesis, thorough physical examination, and adequate interpretation of neuroimaging data is crucial for the early diagnosis and timely therapeutic intervention for such cysts. Conclusion: Surgical approach involving complete lesion resection considerably improves prognosis.

AbstractThis study investigated the factors influencing intravenous methylprednisolone pulse (IVMP) therapy for recovering visual acuity in Chinese patients with aquaporin-4 (AQP4) antibody-seropositive neuromyelitis optica-related optic neuritis (NMO-ON). This retrospective case series included 243 affected eyes of 182 patients (36 male, 146 female) diagnosed with NMO-ON in the Neuro-Ophthalmology Clinic of Beijing Tongren Hospital from September 2012 to September 2020. All patients with AQP4-antibody seropositivity had clinical manifestations of acute ON, excluding other diagnoses and received IVMP treatment at 500 mg/day or 1000 mg/day for 3 days. Primary outcome was the extent of improvement in logMAR visual acuity after IVMP treatment. The therapeutic influences of sex, age, baseline visual acuity, therapeutic intervals, and IVMP dose on acute NMO-ON were analysed. Chi-square tests, Mann–Whitney U-tests, Kruskal–Wallis tests, Spearman’s correlation coefficients, and multiple linear regression were used for statistical analysis. Age ranged between 7 and 80 years (median age, 44; interquartile range [IQR], 29–52) years. Among the 243 eyes, the median improvement in logMAR visual acuity was 0.3 (IQR, 0–0.9). Therapeutic efficacy of IVMP was significantly higher in female than in male patients (Z = 2.117, P = 0.034). The treatment effect gradually decreased with increase in age at onset (Rs = 0.157, P = 0.015), and visual improvement was significantly lower in patients aged > 50 years than in those ≤ 50 years (Z = 2.571, P = 0.010). When patients had low visual acuity at onset, improvements were more obvious (rho =  − 0.317, P < 0.001); however, final visual acuity was still low (rho = 0.688, P < 0.001). Therapeutic effect was negatively correlated with therapeutic intervals (rho = 0.228, P = 0.001). Dosage of methylprednisolone (1000 mg/day or 500 mg/day) did not significantly influence treatment efficacy (Z = 0.951 P = 0.342). Therefore, IVMP therapy can improve visual acuity in the affected eyes of patients with AQP4 antibody-seropositive NMO-ON with similar effect at 500 mg/day and 1000 mg/day doses. Sex, age at onset, and therapeutic intervals may influence the efficacy of IVMP in patients with NMO-ON.

Eye Pain

A 51-year-old White woman sought care for vision loss 1 week after a nonspecific upper respiratory tract infection. She reported pain in both eyes exacerbated by eye movement, which lasted for several days, followed by bilateral vision loss to the level of counting fingers–only vision. Optic neuritis was diagnosed, and she was treated with 1 g intravenous methylprednisolone for 3 days. Her vision improved substantially, and the pain resolved during the corticosteroid treatment. However, 1 week later, she woke up with right eye pain and vision loss. She was again treated with 5 days of intravenous methylprednisolone, with visual improvement nearly back to baseline. Two weeks later, she had recurrence of painful vision loss in both eyes. A diagnosis of chronic relapsing inflammatory optic neuropathy was made. Tests for serum angiotensin-converting enzyme, antineutrophil cytoplasmic antibody, antinuclear antibody, Lyme disease, syphilis, tuberculosis, and aquaporin-4-immunoglobulin G antibodies were negative. Serum was definitively positive for myelin oligodendrocyte glycoprotein-immunoglobulin G antibodies at a titer of 1:1,000. Myelin oligodendrocyte glycoprotein-immunoglobulin G–associated recurrent optic neuritis was diagnosed. After her diagnosis of recurrent corticosteroid-dependent optic neuritis associated with myelin oligodendrocyte glycoprotein-immunoglobulin G positivity, the patient was treated with 5 days of intravenous methylprednisolone. The eye pain resolved, and her vision returned to normal. At follow-up evaluation, the patient’s visual acuity, color vision, and visual fields were normal in both eyes, but there was mild bilateral optic disc pallor. She has not had recurrent demyelinating episodes while on chronic immunotherapy. Optic neuritis is an inflammatory demyelination of the optic nerve manifesting as acute to subacute vision loss, classically associated with pain with eye movement. The long-term prevention and prognosis depend on the cause of the optic neuritis.
