Case presentation: The case concerns an 11-year-old boy who presented with simple and complex vocal tics, motor tics, obsessive-compulsive traits and irritability from the age of 6 years, in addition to a positive result for streptococcal infection. The course of symptoms followed a relapsing-remitting trend with acute phases that were contingent on the infectious episodes. Conclusions: Following eight sessions of EMDR, preceded by training sessions with the parents, the child showed a significant reduction in symptoms and disappearance of the exacerbation. These results indicate the possibility of improving the treatment outcomes of patients with PANDAS by a combined approach using both antibiotic and EMDR therapies.

Although many reports have detailed a range of neurological symptoms in SARS-CoV-2-infected patients, studies of neuro-ophthalmological manifestations are still scarce. Case presentation: We report a 9-year-old girl with abducens nerve palsy after COVID-19 with no evidence of other neurological disease on neuroimaging. At 2-month follow-up clinical conditions were improved. Conclusions: The palsy may have occurred due to a possible post-infectious immune-mediated mechanism underlying the neuropathy, as opposed to direct viral infiltration. Despite being rare, this complication must be taken into account.

Despite what was known about the benignity of this syndrome, there is always more evidence about the involvement of the cognitive functions with different deficits in several domains to be investigated. Aim of the study: The aim of our study was to describe prognostic electroencephalogram (EEG) pattern of an adverse cognitive development to recognize patients at higher risk of lasting cognitive deficits that could need antiepileptic drugs (AEDs) or an improved neurocognitive therapy. In addition, we wanted to investigate the existence of a possible linkage between the number of interictal epileptiform discharges (IEDs) in the EEG and the more pronounced cognitive deficits. Material and methods: We performed a case-control study on a cohort of 16 patients (10 male and 6 female) aged 4-14, diagnosed with BECTS who underwent EEG, magnetic resonance imaging (MRI), and neurocognitive assessment at the Pediatric Neurology Unit at the Umberto I Hospital, Sapienza University of Rome. Patients were divided into two groups according to the percentage of IEDs evaluated based on their sleep EEG: group A with less than 50% of the entire EEG invaded by discharges in more than 70% of the total number of EEG performed, so-called with low or intermediate activation. On the contrary, group B had a high activation, with more than 50% of the entire EEG invaded by discharges in the same percentage of the EEG performed. All children were assessed based on a protocol designed to study neuropsychological functions with specific tests chosen depending on age (Wechsler Intelligence Scale for Children IV: WISC IV; Wechsler Preschool and Primary Scale of Intelligence III: WPPSI III). Groups were compared for cognitive outcomes achieved by each patient through Student's t-test with a significance level of p b 0.05 (two-tailed). Results: There is no statistically significant difference in the cognitive outcomes of these patients: Student's t-test showed a statistical significance (p) for each cognitive index always higher than 0.05, demonstrating that the intellectual quotient (IQ) and all other indexes analyzed (verbal comprehension index (VCI), perceptual reasoning index (PRI), working memory index (WMI), and processing speed index (PSI)) are not affected by the difference in EEG anomalies presented by our patients. Interestingly, all patients had an IQ equal to or greater than the Italian average (12 out of 16 patients showed an IQ N 100), with selective drops, particularly significant in the WMI and also in the PSI. Conclusions: Our results clearly demonstrate the importance of a proper evaluation of patients with this kind of epilepsy, without paying attention only to those with the greatest number of IEDs or seizures because all of them had a neurocognitive impairment, especially in memory. These data may be reinforced by a larger sample for an even more significant statistical value. These results also highlight the importance of a neurocognitive therapy for these children to treat for their specific needs.

During the first part of the pandemic, adults showed mild to severe respiratory symptoms. Children seemed initially exempt, both from acute and subsequent complications. Hyposmia or anosmia were promptly identified as the main symptoms of acute infection, so neurotropism of SARS-CoV-2 was immediately suspected. (1, 2). As the emergency progressed, post infectious neurological complications were described also in pediatric population (3). Cases of cranial neuropathy in connection with acute SARS-CoV-2 infection have been reported in pediatric patients, as an isolate post infectious complication or in the context of the multisystem inflammatory syndrome in children (MIS-C) (4–6). Neuroinflammation is thought to be caused by several mechanisms, among which immune/autoimmune reactions (7), but s...

Its pathogenesis is unknown but it seems triggered by infections, metabolic disturbances, and other inflammatory reactions. PANS represents a neurodevelopmental problem and infant feeding can play a role. Breast milk is the ideal food for infants and influences children's brain, cognitive, and socio-emotional development.Methods:We enrolled 52 children diagnosed with PANS. We interviewed their parents in order to investigate perinatal history, infant feeding, neurologic development, and confounding factors like socio-economic status and region of origin. We subgrouped PANS patients into three subsets: those who only received human milk (HMO), those who only received infant formula, and those who received mixed feeding.Results:The co...

The exact prevalence and pathogenesis of allergy in SIgAD have not yet been defined. We aimed to describe the prevalence and the characteristics of allergy in pediatric SIgAD subjects, evaluate the association between allergy and other comorbidities, and define the immune phenotype of allergic and non-allergic patients. Methods: Clinical and immunological data from 67 SIgAD patients were collected over a 13-year period at a single center. Patients’ characteristics were analyzed according to the presence of allergy. Results: Allergy was diagnosed in 34% of SIgAD patients, with a median age at allergy diagnosis of 8 years. Allergy was the second-most-common clinical manifestation, following recurrent respiratory infections. Among the allergic group, 74% had rhinitis, 30% asthma, 30% atopic dermatitis, and 22% food allergy; one out of three had more than one allergic manifestation. SIgAD patients ...

We hypothesized that there are similar symptoms to those that have been described in adults and children and that pediatric patients with neurophysiologic symptoms still present 3–5 months after infection have psychological consequences that interfere with their adaptive functioning.MethodWe recruited 322 COVID-19-positive pediatric patients, between 1.5 and 17 years old, from the outpatient clinic for COVID-19 follow-up. Neurological symptoms were analyzed at onset, after 1 month, and after 3–5 months. A psychological assessment with standardized questionnaires was also conducted to determine the impact of the disease.ResultsAt the onset of COVID-19, 60% of the total sample exhibited symptoms; this decreased after 1 month (20%) but stabilized 3–5 months after disease onset (22%). Prevailing long-COVID neurological symptoms were headache, fatigue, and anosmia. In the 1.5–5-year-o...

In addition, the child showed speech delay, tremors, and lack of motor coordination. Next Generation Sequencing analysis (NGS) performed in trio revealed in the proband the c.889C>T de novo missense variant in the KCNA2 gene in heterozygous state. This is the first case of myoclonic epilepsy in a toddler due to a c.889C>T KCNA2 missense variant. The patient was treated with valproic acid and ethosuximide with a good clinical response. At 6 years old, follow-up revealed that the proband was seizure-free with tremors and clumsiness in movements. According to the literature, this case supports the correlation between myoclonic epilepsy and KCNA2 alterations. This evidence suggests that performing genomic testing including the KCNA2 gene in preschool patients affected by myoclonic epil...

Clinical manifestations, neurological and psychiatric, laboratory investigations, and familiar history were collected to evaluate the differences between the two groups. The effects of various therapeutic approaches were examined. Descriptive and comparative statistical analyses were performed.Results: The mean age at onset of PANDAS/PANS symptoms was 6.2 ± 1.2 years. The most common di...

The objective of this study was to assess NOX2 activity, as well as serum 8-iso-prostaglandin F2α (iso-PGF2α) and lipopolysaccharide (LPS) derived from Gram-negative bacteria in the gut of patients with PANDAS. Methodsa cross sectional study was performed to compare serum activity of soluble NOX-2-dp (sNOX-2-dp), blood levels of isoprostanes and LPS in 60 consecutive subjects, including 30 children affected by PANDAS and 30 controls (CT) matched for age and gender. Serum zonulin was used to assess gut permeability. Resultscompared with CT, PANDAS children had higher values of sNOX-2-dp, 8-iso-PGF2-alpha and LPS. Simple linear regression analysis showed that sNOX2-dp was significantly correlated with serum LPS (Rs=0.359; p=0.005), zonulin (Rs=0.444; p<0.001) and iso-PGF2α (Rs=0.704; p<...

It is known that streptococcal infections play a role in the etiology of a great number of diseases including Sydenham chorea and rheumatic fever, among others. Based on the suspected pathogenesis of PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections) reported in the medical literature, we decided to investigate the cardiologic involvement in children with a recent PANS/PANDAS diagnosis. Methods: The study population satisfies PANS (1) and PANDAS (2) criteria of diagnoses. Cardiologic assessment was performed through clinical examination, electrocardiography, and echocardiography. Results: In the selected pediatric population, a significant number of children presented mitral valve involvement, systolic murmurs and electrocardiographic abnormalities. High ASLOT levels did not seem to be associated to a cardiac involvement. Conclusions: Often PANS is difficult to diagnose because it is little known by physicians and most of the cardiologic findings described in this study are common among the healthy pediatric population. Also, ASLOT levels seems not to be predictive of cardiac involvement. Furthermore, the existence of PANDAS as a clinical entity is associated with a group of anti-neuronal autoantibodies found in Sydenham chorea is still controversial. We recommend a complete cardiologic evaluation in those children who meet the PANS/PANDAS diagnostic criteria.
