Abstract
Pediatric onset multiple sclerosis (POMS) in the very young is a very rare entity and presents a difficult diagnostic challenge due to overlapping signs and symptoms with other diseases. We present a 4-year-old boy who initially presented with right-sided hemiparesis and demyelinating lesions on MRI. Follow-up MRI examinations 3 and 6 months later revealed new demyelinating lesions. Ten months after initial presentation, he presented with right-sided hemiparesis, central facial nerve palsy on the right side and new demyelinating lesions on MRI. Two clinical events and new MRI lesions on follow-up MRIs confirmed the diagnosis of POMS. He was treated with rituximab and experienced no further relapses or radiological progression during the follow-up period.

Abstract
Juvenile multiple sclerosis (JMS) is a rare but significant subtype of multiple sclerosis (MS) that affects a small percentage of patients under the age of 10 and 3-5% of all MS patients. Despite its rarity, JMS poses unique challenges in terms of diagnosis, treatment, and management, as it can significantly impact a child or adolescent's physical, cognitive, and emotional development. JMS presents with a varying spectrum of signs and symptoms such as coordination difficulties and permanent cognitive dysfunctions and may include atypical clinical features such as seizures, acute disseminated encephalomyelitis, and optic neuritis, making diagnostic evaluations challenging. Whilst the biology of JMS shares similarities with adult-onset MS, there exist notable distinctions in disease progression, clinical manifestations, and ultimate prognoses. The International Pediatric MS Study Group (IPMSSG) was founded in 2005 to improve understanding of JMS, but there remains a lack of knowledge and guidelines on the management of this condition. This review summarizes the current knowledge on JMS, including its epidemiology, clinical presentations, diagnostic challenges, current treatment options, and outcomes. Current treatment options for JMS include disease-modifying therapies, but JMS can also result in impaired quality of life and psychiatric comorbidity, highlighting the need for comprehensive care for affected children. Through gathering and analyzing scattered studies and recent updates on JMS, the authors aim to address the gaps in current knowledge on JMS and provide an improved understanding of appropriate care for affected children. By doing so, this review hopes to contribute to improving the quality of life and outcomes for JMS patients.

Abstract
Multiple sclerosis (MS) is a debilitating autoimmune condition caused by demyelination, neurodegeneration and persistent inflammation of the central nervous system. Pediatric multiple sclerosis (PMS) is a relatively rare form of the disease that affects a significant number of individuals with MS. Environmental exposures, such as viral infections and smoking, can interact with MS-associated human leukocyte antigens (HLA) risk alleles and influence the immune response. Upregulation of immune response results in the disruption of immune balance leading to cascade of inflammatory events. It has also been established that gut microbiome dysbiosis poses a higher risk for pro-inflammation, and it is essentially argued to be the greatest environmental risk factor for MS. Dysbiosis can cause an unusual response from the adaptive immune system and significantly contribute to the development of disease in the host by activating pro-inflammatory pathways that cause immune-mediated disorders such as PMS, rendering the body more vulnerable to foreign attacks due to a weakened immune response. All these dynamic interactions between biological, environmental and genetic factors based on epigenetic study has further revealed that upregulation or downregulation of some genes/enzyme in the central nervous system white matter of MS patients produces a less stable form of myelin basic protein and ultimately leads to the loss of immune tolerance. The diagnostic criteria and treatment options for PMS are constantly evolving, making it crucial to have a better understanding of the disease burden on a global and regional scale. The findings from this review will aid in deepening the understanding of the interplay between genetic and environmental risk factors, as well as the role of the gut microbiome in the development of pediatric multiple sclerosis. As a result, healthcare professionals will be kept abreast of the early diagnostic criteria, accurately delineating other conditions that can mimic pediatric MS and to provide comprehensive care to individuals with PMS based on the knowledge gained from this research.

Abstract
OBJECTIVES Due to a lack of data on pediatric multiple sclerosis (MS) epidemiology in Iran, this study aimed to determine the incidence rate of pediatric MS in Iran. MATERIALS & METHODS All the data of the patients with MS registered in the Ministry of Health and Medical Education of Iran for 20 years were collected in this study; those born in 1982 and diagnosed with the disease and treated since 2000 were included in this study. Therefor The collected variables were patients' age at the time of diagnosis, gender, year of diagnosis, urban or rural residency, and province of residence. Additionally, age-specific incidence rates per 100,000 of the population were calculated. RESULTS This study was performed on 4544 cases of pediatric MS within 2000-2019, of which 997 patients (21.9%) were male. The mean age of the patients with MS at the time of diagnosis was 14.3±4.6 years, and 4414 children (97.1%) lived in urban areas. The incidence rate of pediatric MS in Iran during 20 years increased from 0.26 per 100,000 of the population in 2000 to 1.53 in 2019. CONCLUSION The incidence of pediatric MS in Iran is high, and the development of diagnostic practices in the past decade in Iran has contributed to the detection of this high incidence.

Abstract
Purpose Multiple sclerosis (MS) is one of the most common neurological disorders and a cause of disability in young adults. Adequate stress management in MS patients may merit the benefits of both physical and psychological well-being. This study aimed to evaluate the quality of life in MS patients and its correlation with stress levels and coping strategies. Methods This descriptive and correlational study was conducted among 109 patients diagnosed with relapsing-remitting MS (RRMS). The study was based on a questionnaire designed by the authors and the following standardized questionnaires: the Perceived Stress Scale (PSS-10), the Inventory for Measuring Coping with Stress (Mini-COPE), and the Multiple Sclerosis International Quality of Life Questionnaire (MusiQoL). Results Data analysis showed that 47.71% of the patients experienced a high level of stress, and the most often used strategies under challenging situations included seeking emotional support (2.11) and active coping (1.96). Also, it showed that when the level of stress is higher, the QOL in all domains is lower. Coping strategies such as sense of humor, turning to religion, self-distraction, denial, venting, substance use, behavioral disengagement, and self-blame are negatively correlated with the quality of life of MS. Conclusion Quality of life in MS patients is negatively affected by a higher level of perceived stress. The use of coping strategies such as active coping, positive reframing, acceptance, and seeking emotional and instrumental support is positively correlated with the quality of life of MS patients.

Abstract
Objective The present study represents one of the largest series of pediatric multiple sclerosis (PedMS) in Western Balkan region. This is the first study aimed to evaluate the characteristics of PedMS in the Serbian population. Methods This retrospective study on 54 PedMS, aged 7–17 years, was performed at the Clinic of Neurology and Psychiatry for Children and Youth in Belgrade, Serbia, a tertiary center for the diagnosis and treatment of children with neurological and psychiatric diseases. Results Female to male ratio was 37 (68.5%): 17 (31.5%). Family history of MS was noted in 9.3% and autoimmune diseases in 24.1% patients. Co-occurring migraine was in 7,4%. Monofocal onset of disease was present in 77.8% patients. The most common initial symptoms were optic neuritis (37%), sensory disturbances (31.5%), motor deficit (24.1%), cerebellar (18.5%) and brainstem lesions (16.7%), pain (9.3%), acute disseminated encephalomyelitis like symptoms (1.9%), and hearing loss (3.7%). Visual evoked potentials were pathological in 75.9% of patients. Oligoclonal bands were positive in 68.5% of patients. Magnetic resonance imaging showed periventricular (94.4%), infratentorial (77.8%), juxtacortical and cortical changes (55.6%) and changes in the cervical spinal cord (33.3%). The median EDSS score was 2.0. Conclusion Our cohort significantly differs from the literature data regarding more frequent occurrence of optic neuritis, hearing loss as a first symptom, the relapsing-remitting course of the disease, higher proportion of early onset of disease, presence of co-occurring migraine and the frequent occurrence of epilepsy and other autoimmune diseases in the family.

Abstract
Background Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory and demyelinating disorder of the central nervous system, with a distinct tendency to a perivenous localization of pathological changes. Children are the most affected population and frequently presented after exanthematous viral infections or vaccination. Due to the rarity of this disease, the annual incidence rate in the population is not precisely known. Case Presentation. Here, we present a 28-year-old male HIV-1 positive patient with an acute confusional state, a diminished alert status characterized by somnolence, hypoprosexia, and complex visual hallucinations. Neuroimages reported white matter demyelinating lesions, mainly affecting the semioval centers, the frontal lobe, and the left parietal lobe; hypointense on T1-weighted images, hyperintense on T2-weighted images and fluid-attenuated inversion recovery weighted images, DWI with restricted diffusion, and a parietal ring-enhancing lesion after IV gadolinium administration. Discussion. In HIV positive patients, the demyelinating disorders have a broader clinical spectrum that could be explained by the immunosuppressed state of the patients, the evolution of the disease, the use of medications, the opportunistic infections, and the environment. Due to this highly variable clinical spectrum, ADEM is a significant challenge for the physicians in HIV positive patients, causing a delay in the diagnosis and treatment. Conclusion We suggest that ADEM should be considered among the differential diagnosis in HIV-infected patients with focal or multifocal neurological symptoms, particularly in encephalopathies with multifocal central nervous system involvement without severe immunosuppression.

Abstract
INTRODUCTION Although the frequency of pediatric-onset multiple sclerosis (POMS) has increased in recent decades, it is still highly uncommon, which creates a need for the involvement of more registries from various clinical centers. OBJECTIVE To characterize the demographic, clinical, and paraclinical features of Egyptian patients with POMS. PATIENTS AND METHODS A retrospective chart review study was undertaken on 237 Egyptian patients with demyelinating events which started before the age of 18 years who attended one of five tertiary referral centers in Cairo, Egypt. RESULTS Multiple sclerosis was diagnosed in 186 patients, 47 (25.27%) patients had disease onset before the age of 12 years; "early-onset pediatric multiple sclerosis (EOPMS)". The mean age of disease onset was (14.13±2.49 years), with a female:male ratio of 1.62:1, none of the enrolled patients had a primary progressive course (PPMS), whereas 10 patients (5.38%) had a secondary progressive form. Approximately two-thirds of the patients had monofocal disease onset, and less than 10% presented with encephalopathy; most of them had EOPMS. Motor weakness was the presenting symptom in half of the patients, whereas cerebellar presentation was detected in 34.95%, mainly in EOPMS. Seizures (not related to encephalopathy) were more frequent in those with EOPMS. Initial brain magnetic resonance images were positive in all patients, with detected atypical lesions in 29.03%, enhanced lesions in 35.48%, black holes in 13.98%, and infratentorial in 34.41%. Cervical cord involvement was found in 68.28%. More than two-thirds of the patients received either immunomodulatory or immunosuppressant (IS) treatment throughout their disease course, and about half of them received their treatment within the first year from symptoms onset, with a more favorable outcome, and patients with highly active disease received natalizumab, fingolimod, or other IS. CONCLUSION The results from this registry - the largest for MS in the Arab region to date - are comparable to other registries. Immunomodulatory therapies in POMS are well tolerated and efficacious and they can improve the long-term outcome in children.

Abstract
Introduction Pediatric multiple sclerosis (pMS) is a rare demyelinating disorder with an onset before the age of 18 years. In this study, we aimed to investigate the characteristics of pMS in Tunisian children. Patients and Methods We conducted a retrospective study over 11 years (2005–2016) including all patients diagnosed with pMS according to the International Pediatric Multiple Sclerosis Study Group (IPMSSG) criteria of 2012 and followed up in a tertiary care research center. Epidemiological, clinical, neuroimaging, laboratory, and therapeutic data were collected and analyzed. Results There were 21 patients. The male-female ratio was 1 : 3. Mean age at onset was 11 years (range: 3–17 years). Three patients had type 1 diabetes. Polyfocal presentation was preponderant (81%) with motor dysfunction in 57% of patients. Paroxysmal dystonia was noticed in 24%. All patients were diagnosed with relapsing-remitting form. Interferon beta was prescribed in 80% with a reduction of annual relapse rate. Conclusion The annual incidence of pMS in Tunisian children aged below 18 years could be estimated as 0.05 per 100,000. Singular features in our cohort were the frequent association with type 1 diabetes and the increased occurrence of dystonia. Greater awareness of pMS may be helpful to improve management strategies of children and their families.

Abstract
INTRODUCTION The objective of our study was to present model-based estimates and projections on current and future health and economic impacts of multiple sclerosis (MS) in Canada over a 20-year time horizon (2011-2031). METHODS Using Statistics Canada's Population Health Microsimulation Model (POHEM) framework, specifically the population-based longitudinal, microsimulation model named POHEM-Neurological, we identified people with MS from health administrative data sources and derived incidence and mortality rate parameters from a British Columbia population-based cohort for future MS incidence and mortality projections. We also included a utility-based measure (Health Utilities Index Mark 3) reflecting states of functional health to allow projections of health-related quality of life. Finally, we estimated caregiving parameters and health care costs from Canadian national surveys and health administrative data and included them as model parameters to assess the health and economic impact of the neurological conditions. RESULTS The number of incident MS cases is expected to rise slightly from 4051 cases in 2011 to 4794 cases per 100 000 population in 2031, and the number of Canadians affected by MS will increase from 98 385 in 2011 to 133 635 in 2031. The total per capita health care cost (excluding out-of-pocket expenses) for adults aged 20 and older in 2011 was about $16 800 for individuals with MS, and approximately $2500 for individuals without a neurological condition. Thus, after accounting for additional expenditures due to MS (excluding out-of-pocket expenses), total annual health sector costs for MS are expected to reach $2.0 billion by 2031. As well, the average out-of-pocket expenditure for people with MS was around $1300 annually throughout the projection period. CONCLUSION MS is associated with a significant economic burden on society, since it usually affects young adults during prime career- and family-building years. Canada has a particularly high prevalence of MS, so research such as the present study is essential to provide a better understanding of the current and future negative impacts of MS on the Canadian population, so that health care system policymakers can best plan how to meet the needs of patients who are affected by MS. These findings also suggest that identifying strategies to prevent MS and more effectively treat the disease are needed to mitigate these future impacts.

Abstract
Multiple sclerosis (MS) is a chronic, autoimmune, inflammatory, demyelinating disease of the central nervous system. MS is increasingly recognized in the pediatric population, and it is usually diagnosed around 15 years of age. The exact etiology of MS is still not known, although autoimmune, genetic, and environmental factors play important roles in its development, making it a multifactorial disease. The disease in children almost always presents in the relapsing-remittent form. The therapy involves treatment of relapses, and immunomodulatory and symptomatic treatment. The treatment of children with MS has to be multidisciplinary and include pediatric neurologists, ophthalmologists, psychologists, physiotherapists, and if necessary, pediatric psychiatrists and pharmacologists. The basis of MS therapy should rely on drugs that are able to modify the course of the disease, i.e. immunomodulatory drugs. These drugs can be subdivided into two general categories: first-line immunomodulatory therapy (interferon beta-1a, interferon beta-1b, glatiramer acetate) and second-line immunomodulatory therapy (natalizumab, mitoxantrone, fingolimod, teriflunomide, azathioprine, rituximab, dimethyl fumarate, daclizumab). Treatment of relapses involves the use of high intravenous doses of corticosteroids, administration of intravenous immunoglobulins, and plasmapheresis. We summarize here the current available information related to the etiology and treatment options in MS. Early administration of immunomodulatory therapy is beneficial in adults, while more studies are needed to prove their effectiveness in pediatric populations. Therefore, pediatric MS still represents a great challenge for both, the early and correct diagnosis, as well as its treatment.

Abstract
BACKGROUND Both the United States (US) Food and Drug Administration (FDA) and the European Union (EU) European Medicines Agency (EMA) order pediatric clinical trials as a condition for approval of new compounds. We evaluate clinical value and likelihood of sufficient recruitment for pediatric multiple sclerosis (pMS) studies and discuss US and EU pediatric legislation with pMS as a paradigm. METHODS We analyzed pMS clinical trials requested by the FDA and the EMA and industry-sponsored pMS studies registered on www.clinicaltrials.gov and www.clinicaltrialsregister.eu. RESULTS The FDA demands four and the EMA 15 pMS trials. CONCLUSIONS pMS is rare. Neither FDA nor EMA prioritize compounds for potential benefit in pMS. The EMA in particular orders multiple pMS studies, which will probably not recruit enough patients. Therefore, it is likely that the pMS trial outcomes will not be relevant for evidence-based medicine analyses, clinical practice and a pMS label for the respective drug. EMA requests for multiple pediatric studies have been described in metastasized adolescent melanoma, another very rare pediatric disease. The terms 'ghost studies' and 'therapeutic hostages' have been proposed for such trials and children whose parents are lured into permitting study participation. Clinical studies are not ethical if the probability is high that they will not provide reasonable outcomes. For now, pMS clinicians will have to continue to use new MS drugs in children off-label. They might consider a more proactive international coordinating role in prioritizing and testing new MS compounds in children.

Abstract
AIM Fatigue in children and adolescents with multiple sclerosis (caMS) is currently poorly understood. This review aimed to provide greater insight into this area and direction for future research by evaluating evidence of associations between fatigue and clinical, psychological, and social factors in caMS. METHOD Studies were identified by searching online databases, hand-searching reference lists, and requesting unpublished literature from key authors. Studies that examined fatigue in relation to at least one clinical, psychological, or social factor in caMS were included. Data on design, sample characteristics, measures of fatigue, clinical, psychological, and social variables, and key findings were extracted. Twelve studies were narratively synthesized. RESULTS Clinical factors appeared largely unrelated to fatigue, whereas associations between fatigue and tests of neurocognitive functioning, and fatigue and diagnosable psychiatric disorders, were mixed. However, fatigue and depressed mood consistently correlated. A small number of studies indicated associations between fatigue and reduced quality of life and school performance. INTERPRETATION A sufficient explanatory model of fatigue in caMS is lacking as studies in this area are few and diverse. Future research should endeavour to identify potentially modifiable clinical and psychosocial factors that are associated with fatigue in caMS so that interventions targeting such factors may be developed.

Abstract
Though the mechanisms of action of intravenous immunoglobulins (IVIG) are not completely understood, these drugs are widely used in treatment of autoimmune diseases. In this review, we have analyzed the literature on the use of IVIG in the treatment of autoimmune diseases of the nervous system in children and discuss the management of patients basing on the recommendation of the European Federation of Neurological Societies. The efficacy of IVIG in children has been shown as first line treatment in Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy, dermatomyositis as a second-line drug in the combination with prednisolone or immunosuppressors in patients refractory to treatment with corticosteroids and cytostatics, myasthenic crisis in myasthenia gravis, exacerbations and short-term treatment of severe forms, non-responsiveness to acetylcholinesterase inhibitors, multiple sclerosis as second or third line of treatment in patients with relapsing-remitting course with intolerance to standard immunomodulatory therapy, acute multiple encephalomyelitis with no response to the treatment with high doses of corticosteroids, paraneoplastic syndromes, pharmacoresistant epilepsy and autoimmune encephalitis. Because the right choice of the drug plays a key role, in particular, in children, that determines the efficacy and safety of the treatment, we present the main approaches to the choice of the drug and schemes of treatment of autoimmune diseases of the nervous system in children.

Abstract
AIM To investigate extent and nature of visual pathways involvement in children with clinically isolated syndrome (CIS). METHODS Forty-seven patients (age 11-17y) with CIS, which later proved to be multiple sclerosis (MS) onset, and 30 controls underwent visual evoked potentials (VEP) investigation within 12d from the appearance of the first signs of disease. Latency and amplitude of P100 peak were compared with normative data and between groups. RESULTS In 58% patients, including those without signs of retrobulbar neuritis, significant slowing of conduction along the central visual pathways (P100 latency lengthening) is seen. P100 amplitudes drop (signs of axonal damage) are registered less frequently (29% cases). CONCLUSION The results indicate that visual pathways are often affected in the MS onset; mostly demyelination signs are seen. Despite MRI significance for MS diagnostic, VEPs proved to be still effective in early diagnosis of MS in children.
