RESUMO

AIM: The purpose of this study was to examine the protective and therapeutic effects of okra (Abelmoschus esculentus [AE]) seed extract, with its known antioxidant, immunomodulatory, and anti-inflammatory properties, in an acetaminophen (paracetamol, N-acetyl- para-aminophenol)-induced model of hepatotoxicity and subsequent acute non-traumatic brain damage. MATERIAL AND METHOD: Forty male Wistar rats were randomly divided into five equal groups, control, paracetamol (P), okra seed extract (AE), okra seed extract + paracetamol (P + AE), and okra seed extract + paracetamol + N-acetyl cysteine (NAC) (P + AE + N). AE was administered by oral gavage through a gastric tube at 600 mg/kg/day for seven days. On the eighth day of the procedure, a single 1 g/kg dose of paracetamol and 300 mg/kg NAC were injected via the intraperitoneal route 1.5 h after AE administration. Rat tissue specimens were subsequently subjected to biochemical and histopathological analyses. Levels of markers such as S100 calcium-binding protein B (S100B), neuron-specific enolase (NSE), and matrix membrane metalloproteinase-9 (MMP-9) were investigated from rat serum specimens. Malondialdehyde (MDA) and superoxide dismutase (SOD) were also measured to determine oxidant-antioxidant status. RESULTS: S100B, NSE, MMP-9, MDA levels, and SOD enzyme activities were examined using biochemical methods. MDA levels were significantly lower in the P + AE group and MMP-9 levels in the AE, P + AE, and P + AE + N groups compared to the P group. Histopathological examination results supported the biochemical findings. CONCLUSION: Okra seed extract exhibits a protective and therapeutic effect against non-traumatic brain damage resulting from acute paracetamol intoxication. We think that this benefit of AE derives from its antioxidant property.

RESUMO

Aim The purpose of this study was to evaluate the effects of obesity and overweight on the oral/dental health and blood biochemistry parameters in children.Methods A total of 87 children (29 boys, 58 girls) aged 1-18 presenting to our paediatric endocrinology outpatient clinic were included in the study. The patient group consisted of children with obesity/overweight and the control group consisted of children with normal weight. Paediatric patients were examined simultaneously by a paediatrician and a paediatric dentist. Oral/dental health examinations of all children included in the study were performed by a specialist paediatric dentist and dmft/DMFT (decayed, missing and filled teeth) values were calculated separately in the mixed dentition period. The Community Periodontal Index of Treatment Needs 23 index and the dental plaque 35 index were evaluated at oral/dental health examinations. Oral and dental health examination findings and blood biochemistry parameters were compared between the two groups.Results While DMFT, dental plaque index, blood c-reactive protein (CRP) and parathyroid hormone (PTH) levels were significantly increased in children with overweight/obesity compared to children with normal weight, there was no difference in terms of daily toothbrushing habits and last dental examination times. Overweight/obesity was found to be associated with the dental plaque and DMFT/dmft index, and elevation in the blood biochemistry parameters CRP and PTH among the children in this study.Conclusion The observation of significant elevation in DMFT and dental plaque indices and numbers of filled deciduous teeth showed that oral/dental health problems and dental decay may emerge more frequently in children with overweight/obesity. Children with overweight should be routinely provided with dental care as part of a multidisciplinary team that includes paediatricians and dentists.

RESUMO

OBJECTIVE: The purpose of this study was to investigate the serum levels of mitochondrial metabolism/reactive oxygen species (ROS)-related peptides (hypoxia inducible factor-1α [HIF-1α], fibroblast growth factor-21 [FGF-21], growth differentiation factor-15 [GDF-15]) and key migraine-related neuropeptides (calcitonin gene-related peptide [CGRP], pituitary adenylate cyclase-activating peptide-38 [PACAP-38], substance P [SP], and vasoactive intestinal peptide [VIP]) during migraine attacks and to evaluate their diagnostic value in pediatric migraine. BACKGROUND: There is increasing evidence for the important role of impairment in oxidative mitochondrial metabolism in the pathophysiology of migraine. Potential biomarkers that may reflect the relationship between migraine and mitochondrial dysfunction are unclear. METHODS: A total of 68 female pediatric migraine patients without aura and 20 female healthy controls aged 8-18 years, admitted to the hospital, were enrolled in this cross-sectional study. Serum concentrations of these molecules were determined by enzyme-linked immunosorbent assays, and clinical features and their possible diagnostic value were analyzed. RESULTS: Serum levels of HIF-1α (252.4 ± 51.9 [mean ± standard deviation]) pg/mL), GDF-15 (233.7 ± 24.7 pg/mL), FGF-21 (96.1 ± 13.1 pg/mL), CGRP (44.5 ± 11.3), and PACAP-38 (504.7 ± 128.9) were significantly higher in migraine patients compared to healthy controls (199.8 ± 26.8, 192.8 ± 20.7, 79.3 ± 4.1, 34.1 ± 3.5 and 361.2 ± 86.3 pg/mL, respectively). The serum levels of these peptides were also higher in patients with chronic migraine than in patients with episodic migraine, and higher in the ictal period than in the interictal period. A positive correlation was found between attack frequency and both HIF-1α and FGF-21 levels in migraine patients. Serum levels of VIP and SP were not different between the migraine patients and healthy controls. CONCLUSION: Migraine attacks are accompanied by elevated HIF-1α, FGF-21, GDF-15, CGRP, and PACAP-38 in medication-naive pediatric patients with migraine. Elevated circulating mitochondrial metabolism/ROS-related peptides suggest a mitochondrial stress in pediatric migraine attacks and may have potential diagnostic value in monitoring disease progression and treatment response in children. Novel approaches intervening with mitochondrial metabolism need to be investigated.

RESUMO

AIMS: To investigate the effects of different doses of esculetin on epileptiform activity, behavioral seizures, memory impairment, and cortical and hippocampal NF-κB, as a mediator of pro-inflammatory gene induction, and pro-inflammatory cytokines in penicillin- and pentylenetetrazole(PTZ)-induced seizure models in rats. MAIN METHODS: Different doses of esculetin (5, 10, and 20 mg/kg), and diazepam (5 mg/kg) as a positive control, were tested in penicillin- and pentylenetetrazole(PTZ)-induced seizure models. In the PTZ model, cognitive function, behavioral seizures, and cortical and hippocampal pro-inflammatory biomarkers and survival factor was evaluated. In the penicillin model, the frequency and amplitude of electrophysiological epileptiform activity were assessed. KEY FINDINGS: In the PTZ model, the 10 mg/kg esculetin displayed anticonvulsant effects by extending onset-times of myoclonic-jerk and generalized tonic-clonic seizure, and by diminishing seizure severity and duration of generalized tonic-clonic seizure. It also ameliorated PTZ-induced cognitive impairment, and cortical and hippocampal activin-A, IL-1ß, IL-6 and NF-κB levels. In the penicillin model, the 10 mg/kg esculetin decreased the frequency of spikes without changing the amplitude of spikes. As a positive-control, diazepam reversed all changes induced by both PTZ and penicillin. SIGNIFICANCE: Esculetin exhibits anticonvulsant and memory-improving effects by alleviating the behavioral and electrophysiological characteristics of epileptic seizures. Additionally, esculetin exerts anti-neuroinflammatory actions in the PTZ-induced seizures model. Thus, esculetin may be a multi-targeted promising agent with anticonvulsant and anti-neuroinflammatory effects in the treatment of epilepsy.

RESUMO

Background/aim: Acute necrotizing encephalopathy is a rare type of acute encephalopathy characterized by multi-ocal brain lesions and associated severe neurological findings and various organ dysfunctions may accompany it. Materials and Methods: Patients with acute necrotizing encephalopathy of childhood diagnosed by pediatric neurology and pediatric intensive care at Sami Ulus Maternity, Child Health and Diseases Training and Research Hospital between 2007 and 2020 were included in this study. Results: Nine patients (six females, three males) with a mean age of 4.05 ± 1.94 years (age range 1­6.5) were included in this study. The interval range between fever and encephalopathy in patients was 1­4 days. Influenza A (3H1N1, one untyped) was detected in four patients, influenza B in three patients, and no cause was found in two patients. Major clinical findings other than febrile encephalopathy in all patients were a hemodynamic shock in seven patients, seizures in six patients, vomiting in five patients, dystonia in three patients, and flaccid paralysis in the upper extremity in one patient. Despite all our treatment approaches, including plasmapheresis, moderate to severe neurological sequelae was observed in all of our patients, who survived even with significant radiological improvement. Three patients for whom we could not perform plasmapheresis died. Conclusion: Our study revealed that thalamic involvement increased as the interval shortened, and brainstem involvement increased in patients over four years of age. The presence of persistent vomiting accompanying encephalopathy during the parainfectious period and plasmapheresis treatment being a treatment option that could prevent mortality were cautionary for our study.

RESUMO

Although cerebral palsy (CP), which affects the quality of life of many children and their families, is the most common cause of motor dysfunction in children, no comprehensive bibliometric study has holistically evaluated the publications on CP. This study aimed to analyze the scientific outputs published on CP in pediatrics research between 1980 and 2019 using bibliometric and statistical methods, and reveal new study trends in this field. The literature search was performed in the Web of Science database using the keyword cerebral palsy in the title section of the articles published only in the pediatrics research field. Four-thousand seventy-five publications were obtained in the field of pediatrics research on CP, 3027 of which were articles. We shared abstract information of 3027 articles published between 1980 and 2019 with this comprehensive bibliometric study, which will be a useful guide for physicians and scientists on the global outcomes of CP, and we discussed new trends in this topic. We think that comprehensive bibliometric analyzes on subjects that we frequently encounter in clinics and which are widely researched will contribute to the field.

RESUMO

BACKGROUND/OBJECTIVE: Childhood epilepsy is one of the disease groups with the highest disease burden in society. This study aimed to guide researchers for new studies by determining the most compelling studies and current issues through a bibliometric analysis of scientific outputs about childhood epilepsy between 1980 and 2018. METHODS: The literature review was conducted using the Web of Science (WoS) database. Epilepsy and status epilepticus were used as search keywords in WoS, and the search was performed only in the title section of the publications. Only publications in the research field of pediatrics were included in the study and were analyzed bibliometrically. Linear regression analysis was used to estimate the number of publications in the coming years. RESULTS: It was seen that the number of articles on pediatric epilepsy has been increasing with a linear trend. A total of 3424 publications were found. Of these publications, 2197 (64.2%) articles were analyzed bibliometrically. The top two most productive countries were the USA(654) and Italy (199). The first two most active institutions were The Hospital for Sick Children (40, 1.8%) and Tel Aviv University (38, 1.7%). The top three journals that published the most were Journal of Child Neurology (422, 19.2%), Pediatric Neurology (335, 15.2%), and Developmental Medicine and Child Neurology (201, 9.1%). CONCLUSION: In this bibliometric study on childhood epilepsies, a data summary of 2197 articles published between 1980 and 2018 is presented. We hope that this article will be a useful literature review and guide researchers working on pediatric epilepsy.

RESUMO

BACKGROUND: Symptoms and findings called orange or red flags may indicate the etiology of pediatric headaches and may point to a life-threatening situation requiring urgent treatment and thus can alter patient management. These findings can be either misleading or prognostic for clinicians. We aimed to identify the etiology and prognostic value of orange/red flags in pediatric patients. METHODS: This study included 810 children with headaches who underwent neuroimaging due to the existence of orange/red flags. Their hospital records were examined to obtain demographical, clinical, laboratory data, and re-classify the headaches and determine orange/red flags on admission. RESULTS: Secondary causes were identified in 17.0% (n: 138) of patients, however, those who were diagnosed with a life-threatening headache that required emergency treatment were 5.2% of all patients and 30.4% of the patients diagnosed with a secondary headache. Those with secondary headaches and with life threatening secondary headaches which required urgent treatment were younger (p = 0,018, p = 0,022), had more emergency department visits (p < 0,001), and acute onsets (p < 0,001). Red flags, like systemic symptoms (p < 0,001), sudden onset (p = 0,023, p = 0.039), papilledema (p < 0,001), and progressive headaches (p = 0,048, p = 0.006), were more common with secondary headaches and its subgroup, while headache awakening from sleep (p = 0.009) and family history of primary headache (P > 0,001) were more common in primary headaches. No correlation existed between the number of red flags and etiology. However, older age (p = 0,001) and a shorter duration between symptoms and admission (p = 0,032), and the number of emergency service visits (p = 0,020) increased with increasing red flags. CONCLUSIONS: Physicians always look for flags when they encounter patients with headaches, which is a common symptom, so as not to overlook anything. However, red flags do not always mean that the underlying cause requires emergency treatment and the severity of the cause is not correlated with the number of flags.
