We studied 88 patients with isolated idiopathic optic neuritis (IION) in order to evaluate the rate of progression to multiple sclerosis (MS) in Brazil. The patients were reassessed from one month to nine years after the development of the HON (mean follow-up was 4.6 years). There were 52 men and 36 women with ages ranging from three to 59 years (mean 24.3 years). Bilateral optic neuritis occurred in 19 patients whereas sequential involvement of the fellow eye after an interval longer than four weeks occurred in other 19 patients. Recurrences in the same eye occurred in seven cases. Nine patients (10.8%) developed clinically definitive MS - 13.9% of the women and 7.7% of the men with IION. The median age at the time of diagnosis of MS was 25 years. The mean interval between HON and the emergence of other MS signs varied from one month to five years - median one year. Sixty-seven percent of these, patients developed signs of spinal cord involvement. Our findings when compared to published series in different countries are closer to figures reported in Japan than those in the West.

The timed performances of the 10-m timed walk (TMTW) and the nine-ho le peg test (NHPT) of 881 consecutive patients with multiple sclerosis (MS) undergoing a rehabilitation stay, were expressed as a logarithmic function of time in two subscores to form a composite score called the Short and G raphic A bility Score (SaGA S). The subscores (sS) were constructed in such a way that any interval of 0.5 unit corresponds to a change of 25% in the tests. The SaGA S was computed as the mean of four subscores: SaGAS=(2×2-TMTWsS+NHPTsS right hand+NHPTsS left hand). With the aid of a nomogram, the timed values of the tests are easily transformed into the corresponding subscores, which are then displayed graphically to facilitate follow-up over time. The correlation coefficients between the SaGA S and the two motor components of the MS Functional C omposite (MSFC) (r =0.987), the Expanded Disability Status Scale (EDSS)(r = -0.83), the Nottingham EADL Index (r =0.80) and the Rivermead Mobility Index (RMI) (r =0.90) were all statistically significant (P B-0.001), supporting the validity of the measure. SaGA S had a similar sensitivity to the RMI, but was significantly more sensitive than the EDSS in detecting changes occurring during the rehabilitation stay (14.9% versus 5.0%; P B-0.001) and over a one-year follow-up (35.3% versus 19.7%; P B-0.001). C ompared with the motor components of the MSFC, with which it shares several features, SaGA S has several advantages: it does not depend on the stratification of the study population; it does not skew the results of the NHPT towards improvement at the lower end; and it offers an independent assessment of both hands. SaGA S is a simple, intuitive, nonphysician-based measure, which could provide consistent scoring in future clinical trials.

PURPOSE: To report the clinical features and outcome of a series of children with optic neuritis. METHODS: We reviewed the medical records of patients up to 16 years old with optic neuritis. Group 1 comprised children seen up to two weeks after the onset of visual loss; Group 2 comprised patients already harboring optic atrophy. RESULTS: There were 15 boys and 12 girls. The mean age was 10.9 years. Bilateral optic neuritis occurred in 10. Optic disc pallor was found in 35%, edema in 46%, and 19% had normal fundus. During follow-up visual acuity improved in all but one eye in Group 1, and in six of seven eyes in children in Group 2. Just one child converted to multiple sclerosis. CONCLUSIONS: This study shows that the clinical features of childhood optic neuritis differ from those observed in adults. In children it has a better visual outcome and a lower conversion rate to multiple sclerosis than in adults.

IntroductionOptic neuritis (ON) results in acute loss of vision with pain on eye movement. It may be the first manifestation of multiple sclerosis (MS) and usually follows a resolving course. Here we describe five patients with MS who developed severe unilateral ON resulting in persistent visual loss without significant resolution.MethodsA retrospective clinical review of five cases identified from a database of 550 patients with MS.ResultsAll patients were female and the mean age was 30 years at onset (range 25–40). All patients had no light perception at diagnosis, and received treatment with high dose intravenous methylprednisolone. Two patients also had plasma exchange. All of the patients were subsequently treated with immunomodulatory therapy. The patients were followed for a mean period of 13.3 years (range 2 months to 31 years). None of the patients had significant improvement in their visual acuity, with most achieving vision of 6/60. The mean retinal nerve fibre layer thickness was 66.33 microns (range 46–98 microns) in the affected eye, compared to 86.7 microns (69–105 microns) in the unaffected eye. All patients were aquaporin-4 antibody negative and oligoclonal band positive, with the MRI brain and spine being diagnostic for MS. Interestingly, none of the patients developed significant symptoms in the contralateral eye with vision of 6/5. All patients had an EDSS score of 4.0 predominantly due to visual impairment.ConclusionSevere unilateral ON is rarely seen in MS. This case series highlights a phenotypically distinct group of female MS patients with severe unilateral ON, and no improvement in visual acuity after prolonged follow-up and despite treatment with steroids and potent immune therapies. In such patients, where the diagnosis of MS is confirmed by MRI and CSF analysis, the patient might be reassured that visual loss in the fellow eye is unlikely.References. Wilhelm H, Schabet M.

Background: The visual evoked potentials (VEP) is a valuable tool to document occult lesions of the central visual channels especially within the optic nerve. Objectives: The purpose of the present study was to observe the findings of first few cases of VEP done in the neurophysiology department of the National Institute of Neurosciences (NINS), Dhaka, Bangladesh. Methodology: This cross-sectional study was conducted in the Department of Neurophysiology at the National Institute of Neurosciences and Hospital, Dhaka, Bangladesh from September 2017 to March 2020. All patients referred to the Neurophysiology Department of NINS for VEP were included. Pattern reversal VEPs were done using standard protocol set by International Federation of Clinical Neurophysiology (IFCN). Results: The mean age of the study population was 30.70 (±12.11) years (6-68 years) with 31 (46.3%) male and 36 (53.7%) female patients. The mean duration of illness was 8.71 (±1.78) months (3 days- 120 months). Most common presenting symptom was blurring of vision (37.3%) and dimness of vision (32.8%). Patterned VEP revealed mixed type (both demyelinating and axonal) of abnormality in most cases [29(43.35)]. The most common clinical diagnosis was multiple sclerosis (29.85%) and optic neuropathy (26.87%). In the clinically suspected cases of multiple sclerosis, optic neuropathy and optic neuritis most of the cases of VEP were abnormal and the p value is 0.04 in optic neuropathy and optic neuritis. Conclusion: The commonest presentation of the patients in this series were blurring of vision and dimness of vision. The most common clinical diagnosis for which VEP was asked for, was optic neuritis and multiple sclerosis. Most abnormalities were of mixed pattern (demyelinating and axonal).

OBJECT High-grade malignant spinal cord compression is commonly managed with a combination of surgery aimed at removing the epidural tumor, followed by spinal stereotactic radiosurgery (SSRS) aimed at local tumor control. The authors here introduce the use of spinal laser interstitial thermotherapy (SLITT) as an alternative to surgery prior to SSRS. METHODS Patients with a high degree of epidural malignant compression due to radioresistant tumors were selected for study. Visual analog scale (VAS) scores for pain and quality of life were obtained before and within 30 and 60 days after treatment. A laser probe was percutaneously placed in the epidural space. Real-time thermal MRI was used to monitor tissue damage in the region of interest. All patients received postoperative SSRS. The maximum thickness of the epidural tumor was measured, and the degree of epidural spinal cord compression (ESCC) was scored in pre- and postprocedure MRI. RESULTS In the 11 patients eligible for study, the mean VAS score for pain decreased from 6.18 in the preoperative period to 4.27 within 30 days and 2.8 within 60 days after the procedure. A similar VAS interrogating the percentage of quality of life demonstrated improvement from 60% preoperatively to 70% within both 30 and 60 days after treatment. Imaging follow-up 2 months after the procedure demonstrated a significant reduction in the mean thickness of the epidural tumor from 8.82 mm (95% CI 7.38–10.25) before treatment to 6.36 mm (95% CI 4.65–8.07) after SLITT and SSRS (p = 0.0001). The median preoperative ESCC Grade 2 was scored as 4, which was significantly higher than the score of 2 for Grade 1b (p = 0.04) on imaging follow-up 2 months after the procedure. CONCLUTIONS The authors present the first report on an innovative minimally invasive alternative to surgery in the management of spinal metastasis. In their early experience, SLITT has provided local control with low morbidity and improvement in both pain and the quality of life of patients.

Fifty-four subjects (36 females and 18 males) affected by clinically definite multiple sclerosis (MS) and with onset of the disease at 15 years of age or before were prospectively studied in five Italian MS centres. Female/male ratio was 4.7 in subjects with age ≥12 years, suggesting a role of hormonal changes in triggering MS onset. The mean follow-up duration was 10.9-5.6 years. The functional systems more frequently involved at onset were the pyramidal and brainstem (both in 28% of cases). The onset was monosymptomatic in 31 subjects (57%). The course was relapsing-remitting in 39 subjects (72%) and relapsing-progressive in 15 (28%). Disability was assessed by the Expanded Disability Status Scale (EDSS): the mean score after 8 years of follow up was 3.5 (-2.5). The score was <4 in 68% of cases, between 4 and 6 in 8% of cases, > 6 in 24% of cases. Disability after 8 years was highly predicted by disability in the first year (p=0.008). There was a tendency to a worse prognosis in relation to the number of relapses in the first 2 years (p=0.08). The outcome was not influenced by the characteristics of symptoms at onset, age and gender.

We aimed to assess the efficacy of biologic therapy in refractory non-Multiple Sclerosis (MS) Optic Neuritis (ON), a condition more infrequent, chronic and severe than MS ON. This was an open-label multicenter study of patients with non-MS ON refractory to systemic corticosteroids and at least one conventional immunosuppressive drug. The main outcomes were Best Corrected Visual Acuity (BCVA) and both Macular Thickness (MT) and Retinal Nerve Fiber Layer (RNFL) using Optical Coherence Tomography (OCT). These outcome variables were assessed at baseline, 1 week, and 1, 3, 6 and 12 months after biologic therapy initiation. Remission was defined as the absence of ON symptoms and signs that lasted longer than 24 h, with or without an associated new lesion on magnetic resonance imaging with gadolinium contrast agents for at least 3 months. We studied 19 patients (11 women/8 men; mean age, 34.8 ± 13.9 years). The underlying diseases were Bechet’s disease (n = 5), neuromyelitis optica (n = 3), systemic lupus erythematosus (n = 2), sarcoidosis (n = 1), relapsing polychondritis (n = 1) and anti-neutrophil cytoplasmic antibody -associated vasculitis (n = 1). It was idiopathic in 6 patients. The first biologic agent used in each patient was: adalimumab (n = 6), rituximab (n = 6), infliximab (n = 5) and tocilizumab (n = 2). A second immunosuppressive drug was simultaneously used in 11 patients: methotrexate (n = 11), azathioprine (n = 2), mycophenolate mofetil (n = 1) and hydroxychloroquine (n = 1). Improvement of the main outcomes was observed after 1 year of therapy when compared with baseline data: mean ± SD BCVA (0.8 ± 0.3 LogMAR vs. 0.6 ± 0.3 LogMAR; p = 0.03), mean ± SD RNFL (190.5 ± 175.4 μm vs. 183.4 ± 139.5 μm; p = 0.02), mean ± SD MT (270.7 ± 23.2 μm vs. 369.6 ± 137.4 μm; p = 0.03). Besides, the median (IQR) prednisone-dose was also reduced from 40 (10–61.5) mg/day at baseline to. 2.5 (0–5) mg/day after one year of follow-up; p = 0.001. After a mean ± SD follow-up of 35 months, 15 patients (78.9%) achieved ocular remission, and 2 (10.5%) experienced severe adverse events. Biologic therapy is effective in patients with refractory non-MS ON.
