Abstract
Subacute sclerosing panencephalitis is a rare complication due to persistent measles infection, characterized by cognitive and motor deterioration. Because subacute sclerosing panencephalitis is considered a potentially fatal complication of measles and usually presents in young populations, particularly those with measles infection under the age of 2 years, new approaches to implement vaccination programs must be devised to help avoid the worsening of patient outcome. Until the disease is eradicated globally, children in all regions of the world remain at risk of measles infection and its respective complications, and therefore, the vaccine is considered the optimal preventative measure. The legacy of measles virus goes beyond the immediate complications. Our study, therefore, aims to provide a comprehensive review on the updated insights into subacute sclerosing panencephalitis as a complication, as well as the extent and future considerations pertaining to vaccination programs in the pediatric population.

Abstract
PURPOSE To report the fundus photographs and spectral domain optical coherence tomography (SD-OCT) findings of a patient with subacute sclerosing panencephalitis (SSPE) presenting merely with ocular symptoms. CASE REPORT A 20-year-old patient presented with sudden loss of vision in the left eye (LE). Fundus photograph showed a yellow lesion in the macula and SD-OCT showed increased reflectivity of the inner retinal layers. Disorganization of the necrotizing retinal layers in the LE gradually progressed to the atrophic retina. Then, visual complaints began in the right eye (RE) accompanied by neurological symptoms. SD-OCT revealed the inner and outer plexiform layers edema and interruption of the ellipsoid zone in RE. Fundus photographs showed macular atrophy for both eyes on the day patient died. CONCLUSION This case report demonstrates the SD-OCT findings of SSPE retinitis with close follow-up from the acute retinitis to the total atrophic macula. These unique findings may be considered as characteristical for the diagnosis.

Abstract
Objective Central nervous system infection with Theiler's murine encephalomyelitis virus (TMEV) in C57BL/6J mice can model acquired epileptogenesis. Diet alters the acute seizure incidence in TMEV-infected mice; yet it is unclear whether intestinal dysbiosis may also impact acute or chronic behavioral comorbidities. This study thus assessed the impact of diet sterilization in a specific pathogen-free vivarium on acute seizure presentation, the composition of the gut microbiome, and chronic behavioral comorbidities of epilepsy. Methods Baseline fecal samples were collected from male C57BL/6J mice (4-5 weeks-old; Jackson Labs) upon arrival. Mice were randomized to either autoclaved (AC) or irradiated (IR) diet (Prolab RMH 3000 - UU diets) or IR (Picolab 5053 - UW IR diet). Mice then underwent intracerebral TMEV or PBS injection three days later. Fecal samples were collected from a subset of mice at infection (Day 0) and Day 7 post-infection. Epilepsy-related working memory deficits and seizure threshold were assessed 6 weeks post-infection. Gut microbiome diversity was determined by 16S rRNA amplicon sequencing of fecal samples. Results TMEV-infected mice displayed acute handling-induced seizures, regardless of diet: 28/57 UW IR (49.1%), 30/41 UU IR (73.2%), and 47/77 UU AC (61%) mice displayed seizures. The number of observed seizures significantly differed: UW IR mice had 2.2±2.8 seizures (mean±standard deviation), UU IR mice had 3.5±2.9 seizures, and UU AC mice had 4.4±3.8 seizures during the 7-day monitoring period. The composition of the gut microbiome significantly differed in TMEV-infected mice fed the UU AC diet, with most measured differences occurring in Gram-positive bacteria. TMEV-infected mice fed the UU AC diet displayed worsened chronic working memory. Significance Intestinal dysbiosis evokes stark differences in acute seizure presentation in the TMEV model and vastly influences the trajectory of post-TMEV infection-induced behavioral comorbidities of epilepsy. Our study reveals a novel disease-modifying contribution of intestinal bacterial species after TMEV-induced acute seizures.

Abstract
Subacute sclerosing panencephalitis (SSPE) is a progressive, disabling, and deadly neurological disorder related to measles (rubeola) infection occurring primarily in children. The slow but persistent viral infection occurs in children or young adults and affects their central nervous system (CNS). There have been plenty of reports on SSPE throughout the world, but it is considered a rare disease in developed countries. This research focuses on comparing the current treatments available to prolong the life of patients for over three years after the onset of SSPE. The goal was to identify possible patterns or trends among the treatments in order to find the best possible method to lengthen a patient's life. The results indicated that interferon alpha, inosine pranobex, and ribavirin display the most effective treatment plan and indicate the most potential in discovering a more effective therapeutic for SSPE.

Abstract
BACKGROUND Subacute sclerosing panencephalitis (SSPE) is a rare, non-treatable and fatal neurological complication of measles, still present due to the return of the epidemic linked to the loosening of vaccination policies. Its mechanism remains unexplained. OBJECTIVE The main objective was to investigate explanatory variables relating to the risk of developing SSPE and its pathophysiology. METHODS Literature analysis was focused on different varieties of SSPE: perinatal forms, short-incubation forms similar to acute measles inclusion body encephalitis (MIBE), rapidly evolving forms, forms occurring in the immunosuppressed, adult forms, and family forms. In addition, several studies on the parameters of innate immunity and interferon responses of patients were analyzed. RESULTS Two main data were highlighted: a relationship between the so-called fulminant forms and the prescription of corticosteroids was established. In familial SSPE, two groups were individualized according to the duration of the latency period, prompting an analysis of patient exomes. CONCLUSION Treatment with corticosteroids should be banned. Knowledge of the genes involved and epigenetics should be useful for understanding the pathophysiology of SSPE and other late-onset neurological infections with RNA viruses.

Abstract
BACKGROUND The clinical features and outcomes of subacute sclerosing panencephalitis (SSPE) in younger children are different from those of adults, leading easily to misdiagnosis during the early stage. So far, there are limited data related to SSPE in preschool children. METHODS In order to summarize the clinical data and evolution of SSPE in preschool children and to expand the phenotypes of SSPE, the medical charts of preschool patients diagnosed with SSPE were retrospectively reviewed and analyzed; the clinical outcomes of the enrolled cases were evaluated and followed up. RESULTS Overall, we included three cases in the study. Their onset age was 5 years and 2 months, 4 years and 3 months, and 4 years and 2 months, respectively. All patients presented drop attacks or jerks as the onset symptom, and one patient had concurrent gait disturbance. Atypical periodic complexes on electroencephalography (EEG) were recorded in all patients. The brain magnetic resonance imaging (MRI) findings of two cases showed demyelinating lesions predominantly on the white matter. The neurological conditions of all cases deteriorated rapidly. Two children died at 21 months and 6 months after onset, respectively. The other case progressively developed vegetative status and akinetic mutism within 4 months. CONCLUSIONS In younger children, the characteristic features of SSPE may be seizures and gait instability as onset manifestations, atypical periodic complexes on EEG, and rapid worsening of neurological conditions.

Abstract
Background Subacute sclerosing panencephalitis (SSPE) is a potentially lethal complication of measles infection. Neurological complications take years to manifest after primary viral infection of brain and can lead to blindness in some individuals. Findings A 13-year-old female patient with history of Bell’s palsy 2 months prior, presented with rapidly progressing necrotizing retinitis in both eyes. Soon after, she was unable to walk, developed myoclonic jerks, altered sensorium and loss of bowel and bladder control. Her clinical history, CSF IgG measles antibody analysis, MRI brain and EEG findings confirmed the diagnosis of SSPE. Conclusion SSPE in our case presented as Bell’s palsy and sudden painless diminution of vision due to ocular involvement, and developed full blown disease within 2 months. SSPE can present as a diagnostic challenge and warrants early identification and referral for timely diagnosis and management.

Abstract
PURPOSE/AIM OF THE STUDY Subacute sclerosing panencephalitis (SSPE) is a degenerative disease of the brain caused by a persistent measles virus infection occurring mostly in childhood or early adolescence. The spectrum of epileptic phenomena associated with SSPE is wide, varying from partial or generalized tonic-clonic seizures and atypical absences to myoclonic-atonic attacks. Tonic seizures are very rare in SSPE. MATERIALS AND METHODS Herein, we discuss a case of 25 years old male that presented with adult-onset SSPE with tonic seizures accompanying myoclonic seizures. RESULTS Patient was treated with clonazepam 5 mg/day and an isoprinosine regimen with a dose of 70 mg/kg/day. This is the fourth case of SSPE presenting with myoclonic and tonic seizures and the first case of SSPE with myoclonic and tonic seizures reported in an adult-onset case in the English literature. CONCLUSIONS Adult-onset SSPE with tonic seizures is rare and may be confusing, thus, it is important to recognize the presence of this type of tonic motor seizures in SSPE patients.

Abstract
AIM To characterize the clinical picture, infectious etiology and MRI results of panencephalitis (PANE) in children, depending on the duration of the disease. MATERIAL AND METHODS Children (n=32) with PANE at the age from 3 months up to 17 years were examined for a group of actual viral and bacterial infections. The inclusion criterion was a diffuse lesion of white matter hemispheres on MRI. MRI of the brain and spinal cord, CSF study (pleocytosis, oligoclonal IgG, the main myelin protein (MBP) were performed. The follow-up was 5-10 years. The complex therapy included etiotropic (antiviral) and pathogenetic agents, with priority given to cytoflavin as a drug with a multimodal effect. RESULTS In 84.4% of cases, PANE in children are recorded under the age of 3 years and in 71.9% of cases, are associated with congenital infections with the prevalence of herpes viruses, especially cytomegalovirus (37,8%) and herpes type 6 (21.9%). In 78.3% of cases, PANE have chronic gradual development more often with a delay in the formation of motor and speech/prespeech skills, and manifested with pyramidal, cerebellar and other symptoms in the future. PANE is accompanied by a lesion of the white matter of the hemispheres in 1/2 cases with periventricular localization, less often in infratentorial structures (46.9%) and spinal cord (21.9%). With the duration of symptoms up to 3 months (n=22) PANE are characterized by inflammatory-demyelinating changes, signs of mass effect, contrast+, pleocytosis in CSF and the increase in MBP (average 4.2±0.8 ng/ml), and, with the duration of more than 3 months, by degenerative-sclerosing changes (n=10) and CSF oligoclonal IgG in 90% of cases. CONCLUSION In almost 2/3 of cases, PANE are associated with congenital infections, accompanied by extensive symmetrical foci of demyelination in the CNS, and their clinical and laboratory parameters and outcomes depend on the start of treatment, with the positive dynamics in 75% of cases.

Abstract
Any infectious illness presenting with an eruption in a pregnant patient may be associated with an increased risk of fetal loss. The viruses that can infect the placenta during maternal infection and can be transmitted to the fetus and cause congenital disease include the rubella virus, the measles virus, the varicella zoster virus, parvovirus B19, human cytomegalovirus, arboviruses, and hepatitis E virus type 1. In addition, some bacteria responsible for exanthematous diseases, like Treponema pallidum, can be transmitted during pregnancy from the mother to the fetus and cause fetal loss. All these infectious agents can cause typical and/or atypical exanthems whose etiologic diagnosis is sometimes difficult but important to determine, especially in pregnant women because of the potential risk to the fetus. In the last 20 years, we have extensively studied pityriasis rosea from the clinical and laboratory perspectives, demonstrating the pathogenic role of human herpesvirus (HHV)-6 and -7. We synthesize the available evidence that PR may be associated with active HHV-6/7 infection and therefore with complications during pregnancy and fetal loss. We have also summarized the emerging infectious illnesses of dermatologic interest that may represent life-threatening health conditions for the fetus: measles, rubella, arbovirus infection, and syphilis.

Abstract
Subacute sclerosing panencephalitis is a progressive neurodegenerative disease. It usually occurs 7–10 years after measles infection. The clinical course is characterized by progressive cognitive decline and behavior changes followed by focal or generalized seizures as well as myoclonus, ataxia, visual disturbance, and later vegetative state, eventually leading to death. It is diagnosed on the basis of Dyken’s criteria. There is no known cure for subacute sclerosing panencephalitis to date, but it is preventable by ensuring that an effective vaccine program for measles is made compulsory for all children younger than 5 years in endemic countries.

Abstract
Animal models have provided a wealth of information on mechanisms of epileptogenesis and comorbidogenesis, and have significantly advanced our ability to investigate the potential of new therapies. Processes implicating brain inflammation have been increasingly observed in epilepsy research. Herein we discuss the progress on animal models of epilepsy and comorbidities that inform us on the potential role of inflammation in epileptogenesis and comorbidity pathogenesis in rodent models of West syndrome and the Theiler's murine encephalomyelitis virus (TMEV) mouse model of viral encephalitis-induced epilepsy. Rat models of infantile spasms were generated in rat pups after right intracerebral injections of proinflammatory compounds (lipopolysaccharides with or without doxorubicin, or cytokines) and were longitudinally monitored for epileptic spasms and neurodevelopmental and cognitive deficits. Anti-inflammatory treatments were tested after the onset of spasms. The TMEV mouse model was induced with intracerebral administration of TMEV and prospective monitoring for handling-induced seizures or seizure susceptibility, as well as long-term evaluations of behavioral comorbidities of epilepsy. Inflammatory processes are evident in both models and are implicated in the pathogenesis of the observed seizures and comorbidities. A common feature of these models, based on the data so far available, is their pharmacoresistant profile. The presented data support the role of inflammatory pathways in epileptogenesis and comorbidities in two distinct epilepsy models. Pharmacoresistance is a common feature of both inflammation-based models. Utilization of these models may facilitate the identification of age-specific, syndrome- or etiology-specific therapies for the epilepsies and attendant comorbidities, including the drug-resistant forms.

Abstract
Central nervous system infections can underlie the development of epilepsy, and Theiler's murine encephalomyelitis virus (TMEV) infection in C57BL/6J mice provides a novel model of infection-induced epilepsy. Approximately 50-65% of infected mice develop acute, handling-induced seizures during the infection. Brains display acute neuropathology, and a high number of mice develop spontaneous, recurrent seizures and behavioral comorbidities weeks later. This study characterized the utility of this model for drug testing by assessing whether antiseizure drug treatment during the acute infection period attenuates handling-induced seizures, and whether such treatment modifies associated comorbidities. Male C57BL/6J mice infected with TMEV received twice-daily valproic acid (VPA; 200 mg/kg), carbamazepine (CBZ; 20 mg/kg), or vehicle during the infection (days 0-7). Mice were assessed twice daily during the infection period for handling-induced seizures. Relative to vehicle-treated mice, more CBZ-treated mice presented with acute seizures; VPA conferred no change. In mice displaying seizures, VPA, but not CBZ, reduced seizure burden. Animals were then randomly assigned to acute and long-term follow-up. VPA was associated with significant elevations in acute (day 8) glial fibrillary acidic protein (astrocytes) immunoreactivity, but did not affect NeuN (neurons) immunoreactivity. Additionally, VPA-treated mice showed improved motor performance 15 days postinfection (DPI). At 36 DPI, CBZ-treated mice traveled significantly less distance through the center of an open field, indicative of anxiety-like behavior. CBZ-treated mice also presented with significant astrogliosis 36 DPI. Neither CBZ nor VPA prevented long-term reductions in NeuN immunoreactivity. The TMEV model thus provides an etiologically relevant platform to evaluate potential treatments for acute seizures and disease modification.

Abstract
Vaccination against influenza is recommended during the vaccination period in pregnant women regardless of trimester. In contrast, administration of live vaccines, such as the vaccine against varicella, MMR (measles-mumps-rubella) is contraindicated in pregnant women. Vaccinations against hepatitis B, diphtheria, tetanus, poliomyelitis, hepatitis A can be made as indicated. Vaccination against yellow fever may be considered in pregnant women travelling to endemic countries. In post-partum period, live vaccines may be administered if necessary, especially vaccination against whooping cough for women not to date with their vaccinations. Vaccination against yellow fever is contraindicated in case of breast feeding. Prevention of pertussis in newborns is based in France on vaccination of the mothers in the post-partum period, and the close contacts of the newborn during the pregnancy ("cocooning").

Abstract
Because of insufficient vaccine coverage, there is an outbreak of measles since 2008 in France with an increasing incidence of cases, most of them among children less than 1 year old or young adults. When measles occurs during pregnancy, maternal and fetal morbidity is increased. Particularly pregnant women are exposed to a higher risk of severe respiratory distress that might cause death. Measles virus can be detected in the placenta. Placental infection appears to be involved in some cases of fetal death. The virus is not responsible for congenital defects but can induce histologic damages inside the placenta which may lead to fetal death. Major perinatal risks are also miscarriage and prematurity. When measles occurs in late pregnancy, congenital infection is possible with variable expression and a risk of subacute sclerosing panencephalitis. Non immune pregnant women or neonates exposed to measles should receive an immunoglobulin prophylaxis within 6 days after contact in order to reduce the risk of infection and severe morbidity. In case of declared measles infection, symptomatic treatment can be proposed and tocolysis can be used if preterm labor is associated. Daily fetal monitoring during the 14 days following the beginning of the eruption can be offered when the fetus is viable. Vaccination is recommended for the people born in France after 1980 with 2 doses of vaccine against measles, rubeola and mumps. Measles vaccine, an attenuated living vaccine, should not be administered during pregnancy but must be proposed before pregnancy or during the post-partum period.

Abstract
A review of published literature was undertaken to investigate the maternal and fetal effects of measles infection in pregnancy and to inform the need for post-exposure prophylaxis. There is no evidence to support an association between measles in pregnancy and congenital defects. However, the need for effective post-exposure protection is supported by studies suggesting a high risk of severe maternal morbidity, fetal loss and prematurity. Measles in late pregnancy can also lead to perinatal infection in the infant, which may be associated with a high mortality and the risk of subacute sclerosing panencephalitis. UK guidance recommends using human normal immunoglobulin for susceptible pregnant women exposed to measles. Although there is no direct evidence that this will reduce the complications of measles in pregnancy, it may attenuate disease and therefore reduce the rate of complications. Measures to identify women likely to be susceptible include assessment of age, vaccination history, and/or antibody testing.

Abstract
Subacute sclerosing panencephalitis (SSPE) typically presents with progressive mental deterioration, behavioral changes, and myoclonic jerks. Atypical presentations are not unknown and may result in diagnostic delays. A 9-year-old girl presented with poor balance and ataxia following an episode of upper respiratory tract infection. Neurological examination revealed mild hemiparesis and ataxia. Brain magnetic resonance imaging revealed scattered areas of T2 and fluid-attenuated inversion recovery hyperintensities in the white matter consistent with acute disseminated encephalomyelitis. Despite treatment with intravenous methylprednisolone, intravenous immunoglobulins, and plasmapheresis, progressive neurological worsening occurred. Later during the course of her illness, subacute sclerosing panencephalitis was suspected from the appearance of burst-suppression pattern on electroencephalogram, and the diagnosis confirmed by elevated titers of measles antibodies in cerebrospinal fluid. Physicians taking care of children need to be aware of atypical presentations of subacute sclerosing panencephalitis and must have a high index of suspicion to prevent diagnostic delays and avoid unnecessary diagnostic and therapeutic interventions.

Abstract
Subacute sclerosing panencephalitis is a rare, slow viral infection caused by a defective measles virus. Although it is a rare disease, it is still important in developing countries. The onset is generally between the ages of 5-15 years. We reported the clinical and laboratory profile and nature of 9 patients under the age of 4 years with SSPE. Although it is known that a few patients with SSPE have an acute and rapidly fulminating course, in this study rate of progression was rapidly progressive in 6 patients and progressive in 3 of them on admission. Unfortunately, 4 of them were lost to follow up because of address and/or telephone number alterations. Although the number of patients in this study is not sufficient, we suggest that SSPE patients under the age of 4 years have a poor prognosis as a result of progressive or rapidly progressive course despite medical treatment.

Abstract
We report a 24-month-old male who developed rapidly progressive subacute sclerosing panencephalitis 17 months after measles infection. This patient had a history of measles infection at the age of 7 months and manifested acute encephalitis 1 month later. Developmental delay observed after encephalitis began to improve after a few months. His control electroencephalogram was normal at the age of 14 months. He was admitted to the hospital with flexor spasms and sudden head drops at the age of 24 months. His electroencephalogram revealed slow waves in the posterior regions of the brain. Vigabatrin was begun; his seizures increased with vigabatrin, and adrenocorticotropic hormone was added to the therapy. After five doses of adrenocorticotropic hormone, his clinical findings deteriorated rapidly. His second electroencephalogram revealed periodic discharges synchronized with myoclonias. He was diagnosed as having subacute sclerosing panencephalitis on the basis of clinical and laboratory findings. He lapsed into a vegetative state within a week and died at the age of 25 months. We report this rapidly progressive case to emphasize the importance of recognition of subacute sclerosing panencephalitis before applying steroids in children with myoclonic seizures.
