RESUMO

PURPOSE: This study aims to comprehensively delineate the phenotypic spectrum of ACTL6B-related disorders, previously associated with both autosomal recessive and autosomal dominant neurodevelopmental disorders. Molecularly, the role of the nucleolar protein ACTL6B in contributing to the disease has remained unclear. METHODS: We identified 105 affected individuals, including 39 previously reported cases, and systematically analysed detailed clinical and genetic data for all individuals. Additionally, we conducted knockdown experiments in neuronal cells to investigate the role of ACTL6B in ribosome biogenesis. RESULTS: Biallelic variants in ACTL6B are associated with severe-to-profound global developmental delay/intellectual disability (GDD/ID), infantile intractable seizures, absent speech, autistic features, dystonia, and increased lethality. De novo monoallelic variants result in moderate-to-severe GDD/ID, absent speech, and autistic features, while seizures and dystonia were less frequently observed. Dysmorphic facial features and brain abnormalities, including hypoplastic corpus callosum, parenchymal volume loss/atrophy, are common findings in both groups. We reveal that in the nucleolus, ACTL6B plays a crucial role in ribosome biogenesis, in particular in pre-rRNA processing. CONCLUSION: This study provides a comprehensive characterization of the clinical spectrum of both autosomal recessive and dominant forms of ACTL6B-associated disorders. It offers a comparative analysis of their respective phenotypes provides a plausible molecular explanation and suggests their inclusion within the expanding category of 'ribosomopathies'.

RESUMO

This study aims to assess the neurodevelopmental progress of high-risk infants 2 years post implementation of the Neurodevelopmental Follow-Up Unit (NFU) program at our hospital and explore implementation challenges for insights. Infants were assessed using the Hammersmith Infant Neurological Examination (HINE), The Alberta Infant Motor Scale (AIMS), and Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III). A multidisciplinary team provided comprehensive parent education covering neurologic cues, postural advice, and developmental instructions in accordance with the children's assessment findings. In addition, a pediatric physical therapist provided motor development training emphasizing age-appropriate milestones and functional independence, while child development specialists addressed delays identified through BSID-III assessments. A total of 121 high-risk babies were enrolled during a 2-year period. Results revealed that 9 infants exhibited suboptimal HINE scores at 3-4 months, with only 2 maintaining suboptimal scores at 12-15 months. Similarly, 2 infants with suboptimal AIMS scores at 3-4 months reached normal values at 12-15 months. Comparable improvements were observed in BSID-III scores. While no correlation between HINE and AIMS scores was found at the 3-4-month mark, a significant correlation emerged between AIMS and HINE scores at 6-9 months (r = 0.643, P < .001) and 12-15 months (r = 0.820, P < .001). Encouraging early family education alongside regular monitoring of high-risk newborns appears to have a positive impact on their motor and cognitive development. Consideration of clinical recommendations, such as tailored interventions and periodic assessments, may contribute to optimizing developmental outcomes.

RESUMO

OBJECTIVES: This study aimed to evaluate seizure semiology, electroencephalogram (EEG), magnetic resonance imaging (MRI), and genetic findings, as well as treatment choices in Rett syndrome (RTT). METHODS: A retrospective analysis was conducted on one hundred and twenty cases diagnosed with RTT with a genetic mutation. Data were obtained from nine participating centers. RESULTS: In this study, 93.3 % of patients were female, with typical RTT found in 70 % of cases. Genetic etiology revealed MECP2, FoxG1, and CDKL5 in 93.8 %, 2.7 %, and 1.8 % of cases, respectively. Atypical RTT clinics were observed in 50 % of male cases, with the first EEG being normal in atypical RTT cases (p = 0.01). Generalized tonic-clonic and myoclonic epilepsy were the most common seizure semiologies, while absence and focal epilepsy were less prevalent. Valproate, levetiracetam, lamotrigine, and clobazam were the most commonly used antiepileptic drugs, affecting the severity and frequency of seizures (p = 0.015, p=<0.001, p = 0.022, and p=<0.001, respectively). No significant differences were observed in EEG findings. The initiation of anti-seizure medications significantly altered seizure characteristics (Table 4). A ketogenic diet and vagal nerve stimulation (VNS) correlated with a 50 % improvement in cognitive function, while steroid treatment showed a 60 % improvement. Remarkably, seizures were substantially reduced after VNS application. CONCLUSION: This study underscores the importance of genetic diagnosis in RTT cases with a clinical diagnosis. These preliminary results will be further validated with the inclusion of clinically diagnosed RTT cases in our ongoing study.

RESUMO

Spastic paraplegia type 3A (SPG3A) is the second most common form of hereditary spastic paraplegia (HSP). This autosomal-dominant-inherited motor disorder is caused by heterozygous variants in the ATL1 gene which usually presents as a pure childhood-onset spastic paraplegia. Affected individuals present muscle weakness and spasticity in the lower limbs, with symptom onset in the first decade of life. Individuals with SPG3A typically present a slow progression and remain ambulatory throughout their life. Here we report three unrelated individuals presenting with very-early-onset (before 7 months) complex, and severe HSP phenotypes (axial hypotonia, spastic quadriplegia, dystonia, seizures and intellectual disability). For 2 of the 3 patients, these phenotypes led to the initial diagnosis of cerebral palsy (CP). These individuals carried novel ATL1 pathogenic variants (a de novo ATL1 missense p.(Lys406Glu), a homozygous frameshift p.(Arg403Glufs*3) and a homozygous missense variant (p.Tyr367His)). The parents carrying the heterozygous frameshift and missense variants were asymptomatic. Through these observations, we increase the knowledge on genotype-phenotype correlations in SPG3A and offer additional proof for possible autosomal recessive forms of SPG3A, while raising awareness on these exceptional phenotypes. Their ability to mimic CP also implies that genetic testing should be considered for patients with atypical forms of CP, given the implications for genetic counseling.

RESUMO

BACKGROUND: Various etiologies may underlie optic neuritis, including autoantibody-mediated disorders described in the last decade. We re-examined demographic, clinical, laboratory features and prognostic factors in pediatric patients with autoimmune optic neuritis according to current knowledge. METHODS: Cases of pediatric ON from 27 centers in Türkiye diagnosed between 2009 and 2022 were included for retrospective evaluation. RESULTS: The study included 279 patients, 174 females and 105 males, with a female-to-male ratio of 1.65. The average age at onset was 12.8 ± 3.4 years, and mean follow-up, 2.1 years (range: 1-12.1 years). Patients <10 years old were grouped as "prepubertal" and those ≥10 years old as "others". The diagnoses made at the end of follow-up were multiple sclerosis associated optic neuritis (n = 90, 32.3 %), single isolated optic neuritis (n = 86, 31 %), clinically isolated syndrome (n = 41, 14.7 %), myelin oligodendrocyte glycoprotein antibody associated optic neuritis (n = 22, 7.9 %), and relapsing isolated optic neuritis (n = 18, 6.5 %). Predominant diagnoses were myelin oligodendrocyte glycoprotein antibody associated optic neuritis and acute disseminated encephalomyelitis associated optic neuritis in the prepubertal group and multiple sclerosis associated optic neuritis in the older group. Recurrences were observed in 67 (24 %) patients, including 28 with multiple sclerosis associated optic neuritis, 18 with relapsing isolated optic neuritis, 11 with myelin oligodendrocyte glycoprotein antibody associated optic neuritis, 8 with aquaporin-4 antibody related optic neuritis, and 2 with chronic relapsing inflammatory optic neuropathy. Recurrences were more common among female patients. Findings supporting the diagnosis of multiple sclerosis included age of onset ≥ 10 years (OR=1.24, p = 0.027), the presence of cranial MRI lesions (OR=26.92, p<0.001), and oligoclonal bands (OR=9.7, p = 0.001). Treatment in the acute phase consisted of intravenous pulse methylprednisolone (n = 46, 16.5 %), pulse methylprednisolone with an oral taper (n = 212, 76 %), and combinations of pulse methylprednisolone, plasmapheresis, or intravenous immunoglobulin (n = 21, 7.5 %). Outcome at 12 months was satisfactory, with 247 out of 279 patients (88.5 %) demonstrating complete recovery. Thirty-two patients exhibited incomplete recovery and further combination treatments were applied. Specifically, patients with relapsing isolated optic neuritis and aquaporin-4 antibody related optic neuritis displayed a less favorable prognosis. CONCLUSION: Our results suggest optic neuritis is frequently bilateral in prepubertal and unilateral in peri­ or postpubertal patients. Age of onset 10 or older, presence of oligoclonal bands, and brain MRI findings reliably predict the development of multiple sclerosis. The risk of developing multiple sclerosis increases mostly during the second and third years of follow-up. Relapsing isolated optic neuritis remains a separate group where the pathogenesis and outcome remain unclear. Investigation of predisposing and diagnostic biomarkers and long follow-up could help to define this group.

RESUMO

Objective: Immaturity of the digestive tract and enteric nervous system is a widely accepted theory for infantile colic (IC) etiopathogenesis. The study aimed to show whether neurotrophins that are necessary for normal functioning and development of the gastrointestinal system have a role in the pathogenesis of IC. Materials and Methods: The IC group (n = 75) comprising the mothers of infants with IC and the control group (n = 75) were included to this cross-sectional case-control study. Brain-derived neurotrophic factor (BDNF), glial cell-derived neurotrophic factor (GDNF), ciliary neurotrophic factor (CNTF), and nerve growth factor (NGF) levels of breast milk samples were evaluated by immunosorbent analysis method. Results: The mean age of infants with IC was 7.3 ± 2.8 weeks, while the mean age of the control group was 8.1 ± 2.9 weeks (p = 0.110). No significant difference was found between the breast milk BDNF, GDNF, CNTF, and NGF levels of two groups (p = 0.941, p = 0.510, p = 0.533, p = 0.839, respectively). Conclusions: This is the first report comparing the neurotrophin levels of the breast milk samples taken from the mothers of infants with and without IC. The study demonstrated that breast milk neurotrophin levels of the mothers did not differ significantly between the infants with and without IC.

RESUMO

BACKGROUND: We aimed to analyze pediatric patients with coronavirus disease 2019 (COVID-19) with a diverse spectrum of neurological manifestations in a single center since neurological involvement in children is still poorly understood. METHODS: We performed a retrospective study on 912 children aged between zero and 18 years who had a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test result and symptoms of COVID-19 from March 2020 to March 2021 in a single center. RESULTS: Among 912 patients, 37.5% (n = 342) had neurological symptoms and 62.5% (n = 570) had no neurological symptoms. The mean age of patients with neurological symptoms was significantly higher (14.2 ± 3.7 vs 9.9 ± 5.7; P < 0.001). Three hundred and twenty-two patients had nonspecific symptoms (ageusia, anosmia, parosmia, headache, vertigo, myalgia), whereas 20 patients had specific involvement (seizures/febrile infection-related epilepsy syndrome, cranial nerve palsy, Guillain-Barré syndrome and variants, acute disseminated encephalomyelitis, central nervous system vasculitis). The mean age of the patients with nonspecific neurological symptoms was significantly higher (14.6 ± 3.1 vs 7.7 ± 5.7; P < 0.001). CONCLUSION: This study presents a large number of patients with a diverse spectrum of neurological manifestations. The rare neurological manifestations reported in our study will contribute to better understanding the neurological involvement of SARS-CoV-2 in children. The study also points out the differences of SARS-CoV-2-related neurological manifestations between patients at different ages. Physicians should be alert about recognizing the early neurological manifestations of the SARS-CoV-2 in children.

RESUMO

BACKGROUND: To evaluate the clinical features, demographic features, and treatment modalities of pediatric-onset chronic inflammatory demyelinating polyneuropathy (CIDP) in Turkey. METHODS: The clinical data of patients between January 2010 and December 2021 were reviewed retrospectively. The patients were evaluated according to the Joint Task Force of the European Federation of Neurological Societies and the Peripheral Nerve Society Guideline on the management of CIDP (2021). In addition, patients with typical CIDP were divided into two groups according to the first-line treatment modalities (group 1: IVIg only, group 2: IVIg + steroid). The patients were further divided into two separate groups based on their magnetic resonance imaging (MRI) characteristics. RESULTS: A total of 43 patients, 22 (51.2%) males and 21 (48.8%) females, were included in the study. There was a significant difference between pretreatment and post-treatment modified Rankin scale (mRS) scores (P < 0.05) of all patients. First-line treatments include intravenous immunoglobulin (IVIg) (n = 19, 44.2%), IVIg + steroids (n = 20, 46.5%), steroids (n = 1, 2.3%), IVIg + steroids + plasmapheresis (n = 1, 2.3%), and IVIg + plasmapheresis (n = 1, 2.3%). Alternative agent therapy consisted of azathioprine (n = 5), rituximab (n = 1), and azathioprine + mycophenolate mofetil + methotrexate (n = 1). There was no difference between the pretreatment and post-treatment mRS scores of groups 1 and 2 (P > 0.05); however, a significant decrease was found in the mRS scores of both groups with treatment (P < 0.05). The patients with abnormal MRI had significantly higher pretreatment mRS scores compared with the group with normal MRI (P < 0.05). CONCLUSIONS: This multicenter study demonstrated that first-line immunotherapy modalities (IVIg vs IVIg + steroids) had equal efficacy for the treatment of patients with CIDP. We also determined that MRI features might be associated with profound clinical features, but did not affect treatment response.

RESUMO

BACKGROUND: Although the underlying genetic causes of intellectual disability (ID) continue to be rapidly identified, the biological pathways and processes that could be targets for a potential molecular therapy are not yet known. This study aimed to identify ID-related shared pathways and processes utilizing enrichment analyses. METHODS: In this multicenter study, causative genes of patients with ID were used as input for Disease Ontology (DO), Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes enrichment analysis. RESULTS: Genetic test results of 720 patients from 27 centers were obtained. Patients with chromosomal deletion/duplication, non-ID genes, novel genes, and results with changes in more than one gene were excluded. A total of 558 patients with 341 different causative genes were included in the study. Pathway-based enrichment analysis of the ID-related genes via ClusterProfiler revealed 18 shared pathways, with lysine degradation and nicotine addiction being the most common. The most common of the 25 overrepresented DO terms was ID. The most frequently overrepresented GO biological process, cellular component, and molecular function terms were regulation of membrane potential, ion channel complex, and voltage-gated ion channel activity/voltage-gated channel activity, respectively. CONCLUSION: Lysine degradation, nicotine addiction, and thyroid hormone signaling pathways are well-suited to be research areas for the discovery of new targeted therapies in ID patients.

RESUMO

We aimed to identify nonconvulsive seizures (NCS) and nonconvulsive status epilepticus (NCSE) in a pediatric intensive care unit (PICU). A prospective cohort study on 35 patients who underwent continuous electroencephalographic monitoring in the PICU was done. The patients were evaluated to collect data of their demographics, clinical diagnoses, clinical seizures by electroencephalography, and neuroimaging findings. One case with NCSE and 4 cases with NCS were diagnosed among the 35 patients. The etiology of the patient with NCSE showed antiepileptic drug (AED) withdrawal. The etiology of the patients with NCS included electrical injury, head trauma, subarachnoid hemorrhage, and pneumonia. The findings suggest that younger age, epilepsy, acute structural brain abnormalities, abrupt cessation of AED, and clinically overt seizures before NCSE/NCS are associated with significant risk for NCS/NCSE. In addition, the electrical injury may also be considered as a risk factor for electrographic seizure though such a case has not yet been reported.

RESUMO

OBJECTIVE: Electroencephalography changes that occur during the transition from eyes-closed to the eyes-open state in resting condition are related to the early phase of sensory processing and are defined as activation. The present study aimed to reveal the potential deteriorations that may occur in the initial period of sensory processing in resting electroencephalography between children with subclinical hypothyroidism and a control group. MATERIALS AND METHODS: Electroencephalographies of 15 children with subclinical hypothyroidism and 15 healthy children aged 10 to 17 years were recorded for 2 minutes for EC and 2 minutes for eyes-open conditions in resting state. Absolute electroencephalography band powers (µV2 ) within the delta, theta, alpha, and beta frequency bands were calculated in Fz, Cz, Pz, and Oz electrodes, respectively, for eyes-closed and eyes-open conditions. RESULTS: The results show that, although there was no noteworthy difference between the powers of the electroencephalography frequency bands of children with subclinical hypothyroidism and healthy children during the eyes-open condition, the alpha powers of the control group were significantly higher in all electrodes during the eyes-closed condition. Furthermore, the powers of all frequency bands were observed to decrease in the eyes-open condition in the control group. However, the same net decrease was not observed in the frequency powers of children with subclinical hypothyroidism. CONCLUSION: According to the results of this study, children with subclinical hypothyroidism may experience information processing impairments starting in the early stages of sensory processing.

RESUMO

BACKGROUND: Folate metabolism disorders can affect various organ systems, including the nervous system. 5,10-methenyltetrahydrofolate synthetase deficiency is a rare cerebral folate deficiency in which MTHFS activity is disrupted with low-normal cerebrospinal fluid (CSF) 5,10-methenyltetrahydrofolate levels, while peripheral folate levels are normal. CASE REPORT: We present here a female patient with developmental delay, microcephaly, hypotonia, nystagmus, and seizure in which a distinct brain MRI and CT showed restricted diffusion in the bilateral parietal and occipital lobes, and calcifications of the bilateral putamen, globus pallidus, and caudate nucleus, and the bilateral parietal and occipital lobes. Laboratory tests revealed macrocytic anemia, increased homocysteine, low-normal CSF 5,10-methenyltetrahydrofolate, and low CSF folate, but normal serum vitamin B12 and folate levels. A whole exome sequencing analysis verified the diagnosis of 5,10-methenyltetrahydrofolate synthetase deficiency. CONCLUSIONS: We have added novel knowledge which is nystagmus and hypotonia in the clinical findings, the involvement and restriction of bilateral putamen, globus pallidus, parietal and occipital lobes, and calcification of the bilateral putamen, globus pallidus, caudate nucleus, and parietal and occipital lobes in neuroimaging images and also low CSF folate in the metabolic investigation with the patient in 5,10-methenyltetrahydrofolate synthetase deficiency.

RESUMO

OBJECTIVE: To evaluate the effectiveness and tolerability of clobazam therapy in the pediatric population in terms of seizure semiology, epileptic syndromes, and etiological subgroups. METHODS: A retrospective cohort study was conducted consisting of 1710 epileptic children from eight centers in seven geographic regions of Turkey. The initial efficacy of clobazam therapy was evaluated after three months of treatment. The long-term effectiveness of the drug, overall seizure outcomes, and overall therapeutic outcomes were evaluated during 12 months of therapy. RESULTS: Analysis of initial efficacy after the first three months of clobazam therapy showed that 320 (18.7 %) patients were seizure-free, 683 (39.9 %) had > 50 % seizure reductions, and 297 (17.4 %) had < 50 % seizure reductions. A positive response (seizure-free and >50 % seizure reduction) was determined for focal-onset (62.3 %) seizures, epileptic spasms (61.5 %), and generalized onset seisures (57.4). The highest positive response rate among the epileptic syndromes was for self-limited epilepsy with centrotemporal spikes (SeLECTS). The highest negative response rate was for developmental and/or epileptic encephalopathies (DEEs). Magnetic resonance imaging (MRI) revealed a structural etiological diagnosis in 25.8 % of the cohort. A higher positive response rate was observed at MRI in patients with sequelae lesions than in those with congenital lesions. The seizure recurrence rate was higher in the patient group with epilepsy with genetic and metabolic causes, in individuals with more than one seizure type, and in those using three or more antiseizure drugs. CONCLUSIONS: This cohort study provides additional evidence that clobazam is an effective and well-tolerable drug with a high seizure-free rate (18.7 %), a significant seizure reduction rate (57.3 %), and with excellent overall therapeutic outcomes with a low seizure relapse rate and considerable reversible benefits in the pediatric population.

RESUMO

Calpainopathy is mainly characterized by symmetric and progressive weakness of proximal muscles. Several reports showed that the most common LGMD subtype is LGMDR1 or calpainopathy, which had previously been defined as LGMD2A. Until now, more than 500 likely pathogenic/pathogenic variants in the CAPN3 gene have been reported. However, a clear genotype-phenotype association had not yet been established and this causes major difficulties in predicting the prognosis in asymptomatic patients and in providing genetic counseling for prenatal diagnosis. In this report, we aimed to add new data to the literature by evaluating 37 patients with likely pathogenic/pathogenic variants for the detected variants' nature, patients' phenotypes, and histopathological features. As a result, the general clinical presentation of the 23 different variants was presented, the high frequency of NM_000070.3:c.550delA mutation in Exon 4 was discussed, and some novel genotype-phenotype associations were suggested. We have underlined that calpainopathy can be misdiagnosed with inflammatory myopathies histopathologically. We have also emphasized that, in young or adult patients with mild to moderate proximal muscle weakness and elevated CK levels, calpainopathy should be the first suspected diagnosis.

RESUMO

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.

RESUMO

Children with chronic neurological diseases, including cerebral palsy (CP), are especially susceptible to vaccine-preventable infections and face an increased risk of severe respiratory infections and decompensation of their disease. This study aims to examine age-appropriate immunization status and related factors in the CP population of our country. This cross-sectional prospective multicentered survey study included 18 pediatric neurology clinics around Turkey, wherein outpatient children with CP were included in the study. Data on patient and CP characteristics, concomitant disorders, vaccination status included in the National Immunization Program (NIP), administration, and influenza vaccine recommendation were collected at a single visit. A total of 1194 patients were enrolled. Regarding immunization records, the most frequently administrated and schedule completed vaccines were BCG (90.8%), hepatitis B (88.9%), and oral poliovirus vaccine (88.5%). MMR was administered to 77.3%, and DTaP-IPV-HiB was administered to 60.5% of patients. For the pneumococcal vaccines, 54.1% of children received PCV in the scope of the NIP, and 15.2% of children were not fully vaccinated for their age. The influenza vaccine was administered only to 3.4% of the patients at any time and was never recommended to 1122 parents (93.9%). In the patients with severe (grades 4 and 5) motor dysfunction, the frequency of incomplete/none vaccination of hepatitis B, BCG, DTaP-IPV-HiB, OPV, and MMR was statistically more common than mild to moderate (grades 1-3) motor dysfunction (p = 0.003, p < 0.001, p < 0.001, p < 0.00, and p < 0.001, respectively). Physicians' influenza vaccine recommendation was higher in the severe motor dysfunction group, and the difference was statistically significant (p = 0.029).Conclusion: Children with CP had lower immunization rates and incomplete immunization programs. Clinicians must ensure children with CP receive the same preventative health measures as healthy children, including vaccines. What is Known: • Health authorities have defined chronic neurological diseases as high-risk conditions for influenza and pneumococcal infections, and they recommend vaccines against these infections. • Children with CP have a high risk of incomplete and delayed immunization, a significant concern given to their increased healthcare needs and vulnerability to infectious diseases. What is New: • Influenza vaccination was recommended for patients hospitalized due to pneumonia at a higher rate, and patients were administered influenza vaccine more commonly. • Children with CP who had higher levels of motor dysfunction (levels 4 and 5) were more likely to be overdue immunizations.

RESUMO

AIM: To examine the regional spinal curvatures and movements in the sagittal and frontal planes during sitting position, and the ability to act independently in patients with CP and to compare the differences between children and adolescents with minimal-to-moderate functional limitations. METHOD: Twenty-one participants diagnosed with CP aged 5-16 years were included. The participants' Gross Motor Function Classification System (GMFCS) levels were determined and those at levels I (minimal functional limitation group: minFLG) or II-III (moderate functional limitation group: modFLG) were included. Spinal curvatures, mobilities, and inclinations in the sagittal and frontal planes were evaluated in the sitting position using a hand-held, computer-assisted non-invasive electromechanical device. Participants' functional independence levels were assessed with the Functional Independence Measure (WeeFIM). RESULTS: In the sagittal plane, there were no differences in terms of spinal curvatures between the minFLG and modFLG (p > 0.05). Spinal mobility degrees for flexion (thoracic and lumbar regions and total spine), extension (sacral region), and total spine mobility scores were significantly greater in the minFLG (p < 0.05). In the frontal plane, lumbar spinal curvature significantly increased, and total spine mobility in the right/left lateral motions and functional independence decreased in the modFLG (p < 0.05). INTERPRETATION: The children/adolescents with minimal functional limitations had greater spinal mobility during flexion, extension, and lateral flexions. Spinal curvatures were similar between groups in the sagittal plane. The lumbar region posture scores in the frontal plane observed as lordoscoliosis were higher, and functional independence was lower in the modFLG.

RESUMO

The chromosome 22q11.2 region is highly susceptible to both microdeletions and microduplications that have been known to be responsible for multiple congenital anomaly disorders. We describe a patient of 22q11.2 duplication syndrome presenting with bilateral ptosis who has normal psychomotor development. Cranial magnetic resonance imaging and electromyography with repetitive nerve stimulation were normal. Chromosome microarray analysis was performed, and the patient was found to have a de novo 2.8 Mb duplication at 22q11.21. To our knowledge, bilateral ptosis and normal psychomotor development with 22q11.2 duplication syndrome has not been described. The 22q11.2 duplication syndrome should be considered in the differential diagnosis of ptosis. This case report contributes to an expanding clinical spectrum of patients with 22q11.2 duplication syndrome.

RESUMO

Electrical status epilepticus during slow-wave sleep (ESES) is an epilepsy syndrome with sleep-induced epileptic discharges and acquired impairment of cognition or behavior. Since the disease's original description in 1971, no clear consensus has emerged on diagnostic criteria or optimal treatment. The treatment of ESES can be challenging, often including numerous antiepileptic drugs, immunomodulatory agents, and even surgical interventions. There is little evidence to guide treatment because only retrospective studies and case reports on the efficacy of treatment of ESES are present in literature. In this paper, we aim to analyze the etiopathogenesis of ESES in the new genetic era and to evaluate the treatment modalities in accordance with the genetic data and electroclinic spectrum of ESES.
