RESUMO
BACKGROUND: The aim of this study was to investigate the frequency of sleep problems in adolescents with epilepsy and their caregivers. We also examined the behavioural difficulties in adolescents with epilepsy and compared these behaviors with healthy controls. METHODS: This observational case-control study included 37 adolescents with epilepsy and their caregivers, and 43 healthy age-matched adolescents and their caregivers. The Children`s Sleep Habits Questionnaire (CSHQ), DSM-5 Level 2 Sleep Disorders Scale for Children, and Strengths & Difficulties Questionnaire (SDQ) were used to evaluate sleep habits, sleep problems, and behavioural difficulties in adolescents. The DSM-5 sleep disorder scale for adults was used to evaluate the caregivers` sleep problems. RESULTS: Adolescents with epilepsy had higher sleep problem scores such as daytime sleepiness and overall sleep problems compared with healthy controls. The psychopathological symptoms such as conduct problems, hyperactivity/inattention, and total behavior were also more frequent in adolescents with epilepsy. There was a nonsignificant increase in DSM-5 sleep disturbance score in caregivers of adolescents with epilepsy. Sleep onset delay had a significant negative correlation with total behavioral difficulties (r = -0.44, p < 0.01), and emotional problems (r = -0.47, p < 0.05) in adolescents with epilepsy. Sleep duration was negatively correlated with conduct problems (r = -0.33, p < 0.05), but positively correlated with prosocial score (r = 0.46, p < 0.01) in adolescents with epilepsy. Night waking was positively correlated with total behavioral difficulties (r = 0.35, p < 0.05) and hyperactivity score (r = 0.38, p < 0.05) in adolescents with epilepsy. CONCLUSIONS: Adolescents with epilepsy have more frequent sleep disturbances and maladaptive behaviors such as hyperactivity/inattention, and conduct problems compared with healthy controls, and their caregivers are more vulnerable to sleep problems. Moreover, we also demonstrated a strong association between sleep disturbances and behavioral problems in adolescents with epilepsy.

PURPOSE: Brain monoamine vesicular transport disease is an infantile-onset movement disorder that mimics cerebral palsy. In 2013, the homozygous SLC18A2 variant, p.Pro387Leu, was first reported as a cause of this rare disorder, and dopamine agonists were efficient for treating affected individuals from a single large family. To date, only 6 variants have been reported. In this study, we evaluated genotype-phenotype correlations in individuals with biallelic SLC18A2 variants. METHODS: A total of 42 affected individuals with homozygous SLC18A2 variant alleles were identified. We evaluated genotype-phenotype correlations and the missense variants in the affected individuals based on the structural modeling of rat VMAT2 encoded by Slc18a2, with cytoplasm- and lumen-facing conformations. A Caenorhabditis elegans model was created for functional studies. RESULTS: A total of 19 homozygous SLC18A2 variants, including 3 recurrent variants, were identified using exome sequencing. The affected individuals typically showed global developmental delay, hypotonia, dystonia, oculogyric crisis, and autonomic nervous system involvement (temperature dysregulation/sweating, hypersalivation, and gastrointestinal dysmotility). Among the 58 affected individuals described to date, 16 (28%) died before the age of 13 years. Of the 17 patients with p.Pro237His, 9 died, whereas all 14 patients with p.Pro387Leu survived. Although a dopamine agonist mildly improved the disease symptoms in 18 of 21 patients (86%), some affected individuals with p.Ile43Phe and p.Pro387Leu showed milder phenotypes and presented prolonged survival even without treatment. The C. elegans model showed behavioral abnormalities. CONCLUSION: These data expand the phenotypic and genotypic spectra of SLC18A2-related disorders.

BACKGROUND: Many studies evaluating the nutritional status of children with cerebral palsy (CP) have focused on energy requirements and protein intake. The present work aimed to assess nutritional status and micronutrient levels of children with (CP). METHODS: This multicenter, cross-sectional and observational study was conducted in 10 different cities in Turkey. Data were available for 398 participants. Anthropometric measurements, feeding mode, nutritional status, and micronutrient levels were evaluated. RESULTS: The study was conducted with 398 participants (303 patients and 95 healthy controls). Statistical analysis showed that according to the Gomez Classification, weight-for-age (WFA) revealed malnutrition in 92.6% of children with CP, based on Centers for Disease Control and Prevention percentiles. Measurements of micronutrient levels showed that zinc levels were low in patients, whereas vitamin A levels were low in controls. Phosphorous and manganese levels were significantly lower in malnourished children than in typical children. The results revealed that children consuming enteral nutrition solutions had higher selenium and lower zinc levels than non-consumers. CONCLUSIONS: Malnutrition is not only a protein- or calorie-based problem; micronutrient deficiencies might cause severe health problems. Children with chronic neurological disabilities must be carefully evaluated for these issues. Therefore, nutritional interventions should be adapted to nutrition.

PURPOSE: Although some drugs used in the treatment of epilepsy are known to affect body weight, the hormonal factors responsible have not been sufficiently described. The purpose of this study was to compare insulin, leptin, neuropeptide Y and ghrelin levels in children with epilepsy receiving monotherapy with topiramate (TPM) and valproic acid (VPA), the drugs whose effects on body weight have been most discussed, with those of a control group. METHOD: 48 patients (25 VPA, 23 TPM) aged between 6 and 15.5 years, presenting to the Karadeniz Technical University Medical Faculty Pediatric Neurology Clinic, diagnosed with idiopathic epilepsy or location-related idiopathic epilepsy, and receiving VPA or TPM monotherapy for at least 6 months were included in the study. Twenty-five healthy subjects with similar demographic characteristics were enrolled as the control group. Blood samples were collected from the patient and control groups after fasting for at least 10-12â¯h and again 1 and 2â¯h postprandially. Body mass index (BMI) values were calculated for all cases. VPA levels, glucose, insulin, leptin, neuropeptide Y and ghrelin were investigated in all three separate blood samples. RESULTS: Age, height, weight and BMI were similar between the patient and control groups. Significant weight gain was observed throughout treatment in the VPA group compared to the TPM group. High fasting and postprandial insulin levels were observed in the VPA group. VPA group leptin and neuropeptide Y (NPY) levels were also higher than in the TPM and control groups. No significant difference was determined in ghrelin levels in the patient groups compared to the controls. CONCLUSION: Low blood sugar not being observed, even though insulin levels are high, after fasting and in the postprandial period in epileptic children receiving VPA is indicative of insulin resistance. The elevation in leptin and neuropeptide Y levels observed in the VPA group also suggest this.

Biotinidase deficiency is characterized by severe neurological manifestations as hypotonia, lethargy, ataxia, hearing loss, seizures and developmental retardation in its classical form. Late-onset biotinidase deficiency presents distinctly from the classical form such as limb weakness and vision problems. A 14-year-old boy presented with progressive vision loss and upper limb weakness. The patient was initiated steroid therapy with a preliminary diagnosis of neuromyelitis optica spectrum disorder due to the craniospinal imaging findings demonstrating optic nerve, brainstem and longitudinally extensive spinal cord involvement. Although the patient exhibited partial clinical improvement after pulse steroid therapy, craniocervical imaging performed one month after the initiation of steroid therapy did not show any regression. The CSF IgG index was <0.8 (normal: <0.8), oligoclonal band and aquaporin-4 antibodies were negative. Metabolic investigations revealed a low biotinidase enzyme activity 8% (0.58 nmoL/min/mL; normal range: 4.4 to 12). Genetic testing showed c.98-104delinsTCC and p.V457 M mutations in biotinidase (BTD) gene. At the third month of biotin replacement therapy, control craniospinal MRI demonstrated a complete regression of the lesions. The muscle strength of the case returned to normal. His visual acuity was 7/10 in the left eye and 9/10 in the right. The late-onset form of the biotinidase deficiency should be kept in mind in all patients with myelopathy with or without vision loss, particularly in those with inadequate response to steroid therapy. The family screening is important to identify asymptomatic individuals and timely treatment.

UNLABELLED: P300 event-related potentials (ERPs), objective measures related to cognitive processing, have not been studied in Sydenham's chorea (SC) patients. PURPOSE: To assess cognitive impairment with P300 ERPs. METHOD: Seventeen patients with SC and 20 unaffected healthy children were included. Stanford-Binet test was used for psychometric assessment, and odd-ball paradigm was used for auditory ERPs. RESULTS: There was no significant difference in P300 latencies between the SC-pretreatment group, SC-posttreatment group and control group (p>0.05). Mean interpeak latencies in SC-pretreatment group and SC-posttreatment group showed significant prolongation compared with the control group (p<0.05). Mean interpeak latencies in SC-posttreatment group were significantly decreased compared with SC-pretreatment group (p<0.05). Compared to controls, patients did not show significant difference in Stanford-Binet intelligence examination. CONCLUSION: This report suggests that interpeak latencies and amplitudes of P300 ERPs could be useful for detecting and monitoring cognitive impairment in SC patients.

Os potenciais evento-relacionados à P300 (ERPs), medidas objetivas relacionadas ao processamento cognitivo, não foram ainda estudados em pacientes com Coreia de Sydenham (CS). Objetivo: avaliar o comprometimento cognitivo através dos ERPs P300. Método: foram incluídos 17 pacientes com CS e 20 crianças saudáveis. A avaliação psicométrica foi feita utilizando o teste de Stanford–Binet e, para os ERPs auditivos, foi usado o paradigma odd-ball. Resultados: Não houve diferença significativa nas latências P300 entre os grupos CS pré-tratamento, CS pós-tratamento e grupo controle. (p>0,05). A média das latências interpicos no grupo CS pré-tratamento e CS pós-tratamento apresentava aumento significativo em comparação aos pacientes do grupo controle (p<0,05). A média das latências interpicos no grupo CS pós-tratamento apresentava decréscimo significativo quando comparada àquela do grupo CS pré-tratamento (p<0,05). Comparados aos controles, os pacientes com CS não mostravam diferença significativa em relação aos controles ao teste de Stanford-Binet. Conclusão: Este estudo sugere que as latências interpicos e as amplitudes dos ERPs P300 podem ser úteis para detectar e monitorar a ocorrência de comprometimento cognitivo em pacientes com CS. .
