Background and objective:Optic neuritis (ON) is associated with a 38% ten-year risk of developing multiple sclerosis (MS) in Western populations, but the corresponding risk in non-Western populations is unclear. We conducted this study to estimate the risk of progression to MS after an episode of ON in a South Asian population.Methods:Two hundred and fifty-three patients with idiopathic ON were identified by reviewing records of visual evoked potentials and chart notes from a single academic center spanning the years 1990-2007. A structured telephone interview was then conducted to identify patients who had subsequently received a diagnosis of MS. The diagnosis was corroborated from chart notes, where possible. Cumulative probability of conversion to MS was calculated using Kaplan-Meier survival analysis.Results:The five-year risk of developing MS was 14.6% and the ten-year risk was 24%. Patients (N=218) who had one or more typical demyelinating lesions on baseline brain magnetic resonance imaging (MRI) had a 68% 10-year risk; those with no lesions or non-typical lesions had a 14% risk (p<0.001). Female gender, recurrent ON, and occurrence of ON in winter months were also associated with increased risk (p≤ 0.001). Severity of ON and likelihood of detecting cerebrospinal fluid (CSF) oligoclonal bands were higher in patients who developed MS.Conclusion:Idiopathic ON in Pakistan carries a lower risk of progression to MS compared with Western data. As in Western populations, however, presence of abnormal baseline brain MRI and CSF oligoclonal bands correlate with increased MS risk.

Optic neuritis (ON) patients can be divided into two groups based on the presence or absence of asymptomatic demyelinating lesions (ADLs) on brain MRI. The presence of ADLs is associated with an increased risk of progression to clinically definite multiple sclerosis (CDMS). The clinical data and brain MRI of 110 patients with acute unilateral ON were analyzed. Patients with ADLs had a significantly higher incidence of ON in spring months as compared with patients with no ADLs (p = 0.0024). Increased incidence of ON in spring months was seen in patients with ADLs whether or not they were diagnosed with CDMS on follow-up.

Individual Probability

Using multivariate analyses, individual risk of clinically definite multiple sclerosis (C DMS) after monosymptomatic optic neuritis (MO N) was quantified in a prospective study with clinical MO N onset during 1990 -95 in Stockholm, Sweden. During a mean follow-up time of 3.8 years, the presence of MS-like brain magnetic resonance imaging (MRI) lesions and oligoclonal immunoglobulin (Ig) G bands in cerebrospinal fluid (CSF) were strong prognostic markers of C DMS, with relative hazard ratios of 4.68 {95% confidence interval (CI) 2.21 -9.91} and 5.39 (95% C I 1.56 -18.61), respectively. Age and season of clinical onset were also significant predictors, with relative hazard ratios of 1.76 (95% C I 1.02 -3.04) and 2.21 (95% C I 1.13 -3.98), respectively. Based on the above two strong predicto rs, individual probability of C DMS development after MO N was calculated in a three-quarter sample drawn from a cohort, with completion of follow-up at three years. The highest probability, 0.66 (95% C I 0.48 -0.80), was obtained for individuals presenting with three or more brain MRI lesions and oligoclonal bands in the C SF, and the lowest, 0.09 (95% C I 0.02 -0.32), for those not presenting with these traits. Medium values, 0.29 (95% C I 0.13 -0.53) and 0.32 (95% C I 0.07 -0.73), were obtained for individuals discordant for the presence of brain MRI lesions and oligoclonal bands in the C SF. These predictions were validated in an external one-quarter sample.

Foreign Accent Syndrome

Background Foreign accent syndrome (FAS) consists of a speech rhythm disorder different from dysarthia or aphasia. It is unusually met in multiple sclerosis (MS). Objective We report a case of FAS as an initial symptom of a MS. Methods A right-handed French woman developed an isolated German foreign accent. Brain magnetic resonance imaging (MRI), SPECT and analysis of CSF were performed. Results Brain MRI revealed a large hypersignal on T2-weighted images in the left prerolandic white matter. Single photon emission computed tomography showed a right prerolandic hypoperfusion. Unmatched oligoclonal bands in cerebrospinal fluid and occurrence of new abnormal hypersignals on the following MRI led us to diagnose MS. Conclusion FAS may be the first symptom of MS. It could result from extensive disturbances of brain function involving the right hemisphere.

Background Cigarette smoking increases the risk for development of multiple sclerosis and modifies the clinical course of the disease. In this study, we determined whether smoking is a risk factor for early conversion to clinically definite multiple sclerosis after a clinically isolated syndrome. Methods We included 129 patients with a clinically isolated syndrome, disseminated white-matter lesions on brain magnetic resonance imaging, and positive oligoclonal bands in the cerebrospinal fluid. The patients’ smoking status was obtained at the time of the clinically isolated syndrome. Results During a follow-up time of 36 months, 75% of smokers but only 51% of non-smokers developed clinically definite multiple sclerosis, and smokers had a significantly shorter time interval to their first relapse. The hazard ratio for progression to clinically definite multiple sclerosis was 1.8 (95% confidence interval, 1.2–2.8) for smokers compared with non-smokers ( P = 0.008). Conclusions Smoking is associated with an increased risk for early conversion to clinically definite multiple sclerosis after a clinically isolated syndrome, and our results suggest that smoking is an independent but modifiable risk factor for disease progression of multiple sclerosis. Therefore, it should be considered in the counseling of patients with a clinically isolated syndrome.

A 13-year-old girl presented with a 5-day history of oscillopsia. On examination, ocular flutter and mild cerebellar signs were found. Brain magnetic resonance imaging (MRI) revealed four periventricular and subcortical non-enhancing lesions. Cerebrospinal fluid (CSF) oligoclonal bands were negative. Neuroblastoma or other malignancies were not found. She responded well to a corticosteroid–intravenous immunoglobulin (IVIG) combination and remained symptom-free for 3 years until presenting again with isolated ocular flutter. Brain MRI at this time remained atypical for classic multiple sclerosis (MS) with a predominance of juxtacortical demyelinating lesions. CSF was positive for oligoclonal bands. Serum myelin oligodendrocyte glycoprotein (MOG) antibodies were present. Ocular flutter can be the presenting feature of MOG antibody–associated pediatric demyelination.

Devic’S Neuromyelitis Optica

Devic's neuromyelitis optica (NMO) associates optic neuritis and myelopathy without other neurological signs. Many patients with NMO may be diagnosed as having multiple sclerosis (MS). However, there have been no previous studies comparing these two patho logies and it is still unclear if NMO is a separate entity or a subtype of MS. In the present study, we compared a series of NMO patients with a series of MS patients for whom optic neuritis or myelopathy was the presenting symptom, in order to determine the place of NMO in the spectrum of MS. We retrospectively studied 30 patients diagnosed with NMO and we compared these patients with 50 consecutive MS cases revealed by optic neuritis or acute myelopathy. MS patients were only included if a relapse occurred demonstrating time and space dissemination. We compared the two groups in terms of clinical presentatio n, laboratory findings (MRI and C SF) and clinical outcome. NMO patients were older and more frequently women than MS patients but the difference was not significant. C SF and MRI data were clearly different: oligoclonal bands (O C B) were found in 23% of NMO cases and 88% of MS (P B/0.001), abnormal brain MRI data were observed in 10% of NMO cases and 66% of MS (P B/0.001) and a large spinal cord lesion was observed in 67% of NMO cases and 7.4% of MS cases (P B/0.001). C linical outcome was evaluated as more severe in the NMO group (P B/0.001). O n the basis of clinical data, all NMO patients but three had dissemination in time and space. When we included MRI parameters, only two of the NMO patients met criteria for MS and one of the MS patients met criteria for NMO. O ur study demonstrates that NMO and MS should be considered as two different entities. The respective criteria for NMO and MS were able to distinguish these two patho logies but only when MRI data were applied. This finding could have implications for future therapeutic trials.

The revision of MEDLINE from 1966 to 2003 did not report any association between multiple sclerosis (MS) and Melkersson—Rosenthal syndrome (MRS). This is a case report of a 51-year-old woman, with history of four recurrent Bell’s palsies. In 1999 she developed a right facial paralysis due to a supranuclear pyramidal lesion with right monoparesis. The family history showed five relatives with recurrent Bell’s paralysis and plicata tongue. Physical examination: right Bell’s paralysis, left supranuclear facial paralysis, furrowed tongue, right hemiparesis with pallor of the optic disks. Brain magnetic resonance imaging (MRI) demonstrated the typical lesions of MS and CSF oligoclonal bands. This is the first observation of a patient with hereditary MRS and MS. The link between both diseases is discussed.

Twenty-seven patients with acute monosymptomatic optic neuritis were randomly selected from a population-based cohort of patients extensively screened for known etiologies of ON. Paired serum and CSF obtained median 20 days from onset were examined for oligoclonal IgG, free kappa and free lambda chains, and virus-specific oligoclonal IgG antibodies by an affinity-mediated capillary blot technique. CSF-restricted oligoclonal IgG bands, free kappa and free lambda chain bands were observed in 17, 15 and nine patients, respectively. In addition, 16 patients showed a polyspecific intrathecal synthesis of oligoclonal IgG antibodies against one or more viruses (12 measles, nine varicella zoster, six rubella, six mumps) compared to all the 18 examined patients with definite multiple sclerosis (P=0.0014). The presence of virus-specific oligoclonal IgG was significantly related to the results of oligoclonal IgG (P=0.0034), free kappa chain bands (P=0.0020), and brain MRI abnormalities (P=0.0402). At 1 year follow-up five patients had developed clinically definite multiple sclerosis; all had virus-specific oligoclonal IgG antibodies, oligoclonal IgG and abnormal MRI at onset.

The Relationship

Background: Some environmental factors have been already associated to increased risk of multiple sclerosis (MS), but it is plausible that additional factors might play a role. Objective: To investigate in MS patients the relationship between inflammatory activity, detected by brain magnetic resonance imaging (MRI) with gadolinium (Gd), and air pollution, namely, particulate matters with diameter less than 10 μm (PM10). Methods: We analyzed from 52 remitting MS patients 226 brain MRIs, 34% with (Gd+MRI) and 66% without (Gd-MRI) T1-Gd-enhancing lesions. Daily recording of PM10 in the 30 days before MRI examination was obtained by monitors depending on the residence of subjects. Results: PM10 levels in the 5, 10, 15, 20, and 25 days before brain MRIs were higher (plus 16%, 21%, 24%, 25%, and 21%, respectively) with reference to Gd+MRI versus Gd-MRI. There was a significant association between Gd+MRI and PM10 levels ( p = 0.013), independent of immune therapies, smoker status, and season. In patients who had two repeated MRIs with opposite outcomes (Gd-MRI and Gd+MRI), PM10 levels were strongly higher in concurrence with Gd+MRI ( p < 0.0001). Conclusion: Our findings suggest that air pollution may be a risk factor for MS favoring inflammatory exacerbations.

Background:Optic Neuritis (ON) is one of the most common clinically isolated syndromes which develops into clinically diagnosed Multiple Sclerosis (CDMS) over time.Objective:To assess the conversion rate of Iranian patients presenting with idiopathic ON to CDMS as well as monitoring potential demographic and clinical risk factors.Methods:Atotal of 219 patients' medical records of idiopathic ON from March 2001 to May 2009 were reviewed. Demographic findings, ophthalmologic characteristics on admission and discharge, diagnostic approaches, type and dosage of therapy were retrospectively reviewed. A structured telephone interview was then conducted to identify patients who had subsequently been diagnosed with MS. Survival analysis was used to evaluate the cumulative probability of MS conversion and contributory risk factors.Results:From the 219 ON patients, 109 [age 11-51, female: 81%] were followed up. Among the male gender the mean age of patients developing MS was significantly lower (P=0.01). In cox regression model, female sex (p=0.07), bilateral ON (p=0.003), MRI abnormalities (p <0.001) and high dose (5g) corticosteroid therapy (p<0.001) were identified as risk factors for the development of MS. The two and five year cumulative probability of developing MS were 27% and 45%, respectively.Conclusions:Idiopathic ON in Iranian patients carries higher risk of progression to MS compared to other Asian countries. MRI lesions are the strongest independent risk factor of developing CDMS. Bilateral ON, female gender and high dose corticosteroid therapy are also important factors in predicting CDMS development.
