Saker Z, Rizk M, Merie D, Nabha RH, Pariseau NJ, Nabha SM, Makki MI. Insight into brain sex differences of typically developed infants and brain pathologies: A systematic review. Eur J Neurosci 2024. [PMID: 38693604 DOI: 10.1111/ejn.16364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 03/12/2024] [Accepted: 04/02/2024] [Indexed: 05/03/2024]
Abstract
The continually advancing landscape of neuroscientific and imaging research has broadened our comprehension of sex differences encoded in the human brain, expanding from the hypothalamus and sexual behaviour to encompass the entire brain, including its diverse lobes, structures, and functions. However, less is known about sex differences in the brains of neonates and infants, despite their relevance to various sex-linked diseases that develop early in life. In this review, we provide a synopsis of the literature evidence on sex differences in the brains of neonates and infants at the morphological, structural and network levels. We also briefly overview the present evidence on the sex bias in some brain disorders affecting infants and neonates.

Abstract
BACKGROUND While generally self-limited, febrile seizures result in significant familial distress. Ambulatory pediatric care providers must be prepared to counsel families on the causes, risk factors, management principles, and prognosis of children with febrile seizures. OBJECTIVE To provide an updated, evidence-based review of febrile seizures focused on the needs of an ambulatory pediatric care provider. METHODS A narrative review of the literature prioritizing landmark articles, metanalyses, longitudinal population longitudinal cohort studies and national level guidelines. RESULTS Febrile seizures are aberrant physiological responses to fever in children caused by complex interactions of cytokine mediated neuroinflammation, environmental triggers, and genetic predisposition. Other than investigations to determine fever etiology, routine bloodwork, lumbar punctures, neuroimaging and electroencephalograms are low yield. The general prognosis is excellent, however, clinicians should be aware of long-term outcomes including: cognitive impairment with non-simple febrile seizures; neuropsychiatric associations; recurrent febrile seizure and epilepsy risk factors; and the association between complex febrile seizures and sudden unexpected death. Children with a high risk of recurrence, complex febrile seizures, limited access to care, or extreme parental anxiety may benefit from intermittent oral diazepam prophylaxis. CONCLUSION Clinicians should consider four management priorities: 1) terminating the seizure; 2) excluding critical differential diagnoses; 3) investigating fever etiology; and 4) providing adequate counselling to families. The clinical approach and prognosis of febrile seizure can be based on subtype. Children with non-simple (i.e. complex or febrile status epilepticus) febrile seizures require closer care than the vast majority of children with simple febrile seizures, who have excellent outcomes.

Abstract
INTRODUCTION Febrile seizures are the most common type of seizure in children under the age of 5, and a number of risk factors for this condition have been identified. Several studies have examined the connection between iron deficiency anemia and febrile seizures in children, with inconsistent results. As a result, the authors sought to determine the precise link between iron deficiency anemia and its indices (mean corpuscular volume, serum iron, total iron-binding capacity, and ferritin) in conjunction to febrile seizures. Methods: A systematic literature search from several databases (PubMed, Europe PMC, ScienceDirect) was conducted from database inception until November 30, 2022. Studies were eligible if they investigated the relationship of the iron deficiency anemia and the aforementioned indices with the likelihood of febrile seizures. Results: This meta-analysis comprised 20 case-control studies with a total of 3856 participants. Our study revealed that iron deficiency anemia, low mean corpuscular volume, low serum iron, high total iron-binding capacity, and low ferritin were associated with the incremental risk of developing febrile seizures, with the odds ratios ranging from 1.24 to 1.59. Moreover, diagnostic test accuracy meta-analysis indicated that low serum ferritin level had the highest overall area under the curve value amid other iron deficiency anemia indices regarding our outcomes of interest. Conclusion: This study suggest that iron deficiency anemia and poor iron indices are associated with increased risk of febrile seizures in children.

Seasonal Trend of Viral Prevalence and Incidence of Febrile Convulsion: A Korea Public Health Data Analysis. CHILDREN 2023; 10:children10030529. [PMID: 36980087 PMCID: PMC10047246 DOI: 10.3390/children10030529] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 03/04/2023] [Accepted: 03/08/2023] [Indexed: 03/11/2023]
Abstract
Febrile convulsion (FC) is the most common seizure disease in children, which occurs with a fever. We investigated the Korean Health Insurance Review and Assessment Service data of patients aged between 6 months and 5 years at the time of FC diagnosis. Diseases that can cause seizures with fever, such as neoplasms, metabolic disorders, nervous system disorders, cerebrovascular diseases, perinatal problems, and congenital abnormalities, were excluded. Weekly virus-positive detection rate (PDR) data were obtained from the Korea Disease Control and Prevention Agency for adenovirus, parainfluenza virus, respiratory syncytial virus (HRSV), influenza virus, coronavirus (HCoV), rhinovirus (HRV), bocavirus, metapneumovirus (HMPV), rotavirus, norovirus, and astrovirus. Using the Granger test, we then analyzed the monthly PDR and investigated the association between FC incidence and monthly PDR. We additionally identified monthly and seasonal FC incidence trends using the autoregressive integrated moving average. Between 2015 and 2019, 64,291 patients were diagnosed with FC. Annually, the incidence was the highest in May and the lowest in October. Most patients were diagnosed during the spring (26.7%). The PDRs for HRSV, HCoV, HRV, HMPV, and norovirus were associated with FC incidence after 1 month.

Abstract
BACKGROUND Patients with complex febrile seizures (CFS) often display abnormal laboratory results, unexpectedly prolonged seizures, and/or altered consciousness after admission. However, no standardized values have been established for the clinical and laboratory characteristics of CFS in the acute phase, making the management of CFS challenging. This study aimed to determine the clinical and laboratory characteristics of children with CFS during the acute phase. In particular, the duration of impaired consciousness and the detailed distribution of blood test values were focused. METHODS We retrospectively reviewed medical records of a consecutive pediatric cohort aged 6-60 months who were diagnosed with CFS and admitted to Kobe Children's Hospital between October 2002 and March 2017. During the study period, 486 seizure episodes with confirmed CFS were initially reviewed, with 317 seizure episodes included in the analysis. Detailed clinical and laboratory characteristics were summarized. RESULTS Among 317 seizure episodes (296 children with CFS), 302 required two or fewer anticonvulsants to be terminated. In 296 episodes showing convulsive seizures, median seizure duration was 30.5 min. The median time from onset to consciousness recovery was 175 min. Impaired consciousness lasting > 6, 8, and 12 h was observed in 13.9%, 7.6%, and 1.9% patients with CFS, respectively. Additionally, the distribution of aspartate aminotransferase, lactate dehydrogenase, creatinine, and glucose were clarified with 3, 10, 50, 90, and 97 percentile values. CONCLUSION This study detailed the clinical and laboratory findings of acute-phase CFS using the data of the largest 15-year consecutive cohort of children with CFS. These results provide important information for appropriate acute management of CFS.

Abstract
Two to five percent of infants and children experience febrile seizures (FS). Breastfeeding is beneficial to the health of mothers and children. Nevertheless, the benefits of breastfeeding in reducing FS remain unclear; thus, the present study aimed to evaluate this association. The case group was selected from 2010 to 2019, and the selected population was children younger than 5 years (i.e., children born from 2005−2019). The control group was selected from newborn infants at our hospital born between 2005 and 2019. Finally, 55 children with FS and 110 children in the control group were recruited. The results show longer breastfeeding duration is associated with an increased risk of FS (adjusted odds ratio: 1.06, 95% confidence interval: 1.01−1.11, p = 0.028). When comparing cases of FS with the control group, the percentage of inclusive breastfeeding over 12 months (32.7% vs. 9.1%, p = 0.017) and longer duration of exclusive breastfeeding were higher (10.86 ± 11.82 vs. 5.40 ± 7.17 months, p < 0.001). However, the comparison of the prevalence of FS between the different breastfeeding duration groups did not reach statistical significance. In conclusion, our study showed that a longer breastfeeding duration was associated with a higher risk of FS. Future large-scale studies evaluating the association between breastfeeding duration and febrile seizures are needed.

Abstract
Abstract
Background
Globally, febrile convulsions (FC) constitute a respected prevalence scale among pediatric population. This usually induces a high parental anxiety.
Aim
To investigate the local community diversity of perception as regards FC.
Method
A cross-sectional anonymous Arabic questionnaire-based study took place targeting the Saudi community. The study included parents with at least a child who underwent FC. Excluded, were those who have children with convulsions due to other causes rather than FC.
Results
Eight hundred participants have fulfilled the study inclusion criteria. Majority of them (84%) were mothers. While 10.9% had only one child diagnosed with FC. Participants believed that FC may induce brain damage (41.4%). Others expressed FC attacks to be life-threatening events (52.9%). They were convinced that FC is not related to epilepsy (40.2%). However, a respected percentage of participants denoted the importance of using oral protective devices during the attacks (41.4%). Overall, most study population (84%) had poor perception of the different aspects of FC.
Conclusion
Social perception of FC problems may be significantly related to the educational level and profession of the parents. The majority of the study subjects have poor perception as regards FC. Therefore, holistic socially oriented educational programs are needed to orient the population about the problem. They may be implemented via various approaches.

Abstract
Objectives Seizures are the most common neurological illness in the pediatric population and account for 1% of all emergency department (ED) visits and 2% of all visits to children's hospital EDs. Pediatric epilepsy presents with various diagnostic challenges. Neuroimaging, especially structural neuroimaging and preferably MRI brain, plays an essential role in diagnosing, managing, and guiding pediatric epilepsy treatment.The study aimed to estimate the clinical spectrum of seizures in children and examine the neuroimaging findings in children with seizures. Materials & Methods The study was a hospital-based retrospective observational study. The hospital case records of all children belonging to the age group 1 month to 12 years with 'seizures' were reviewed for 5 years from Jan 2016 to Dec 2020. Clinicodemographic profiles and neuroimaging (CT/MRI) findings were obtained, and descriptive statistics were applied. Results A total of 838(11%) children in the age group 1 to 144 months (mean±SD: 32.57±32.65) presented with seizures, of whom 515(61.5%) were boys and 323(38.5%) girls. Of 596(71.1%) children under five years, 409(68.6%) had febrile seizures. Generalized onset-motor seizures were the predominant type of seizures seen in 666(79.4%) children, of whom 434(65.1%) had febrile seizures.Neuroimaging (CT/MRI) was normal in 335(40%) and abnormal in 124(14.8%) children. Perinatal insult (7%) was the most common abnormality, followed by CNS infections (2.8%). Conclusion Neuroimaging, preferably MRI brain, is the most helpful tool for the etiological diagnosis of afebrile seizures.In our study, seizures secondary to perinatal insult/hypoxic insult followed by infections were major causes. Improvement in peripartum and perinatal care coupled with a targeted Tuberculosis control program may help in reducing these potentially preventable causes.

Abstract
We investigated the recent epidemiology and characteristics of influenza-related hospitalization in Japanese children. This study included 3741 children with influenza. Children hospitalized for febrile seizures (FS) induced by etiologies other than influenza also served as a disease control. Most outpatients (92.8%) visited our hospital with complaints of respiratory symptoms, whereas FS were the most predominant symptoms of inpatients (58/154, 37.7%). Children with influenza-induced FS were significantly older than those with FS induced by other etiologies (P <0.001). Although the characteristics of severe influenza may vary throughout the world, the analysis of influenza-induced neurological disorders is important for understanding its epidemiology.
