Febrile seizure (FS) is a common pediatric neurological disorder, which may be associated with hypoxia and kidney injury. We aimed to investigate serum levels of neutrophil gelatinase-associated lipocalin (NGAL) in children with FS. This case-control study included 50 children with FS, 50 febrile controls (FCs), and 50 healthy controls (HCs).

Background: The residual burden of coronary artery disease (CAD) after percutaneous coronary intervention (PCI) drew a growing interest. The residual SYNTAX Score (rSS) was a strong prognostic factor of adverse events and all-cause mortality in patients who underwent PCI. In addition, the SYNTAX Revascularization Index (SRI), a derivative of rSS, was used to figure out the treated proportion of CAD and could be used as a prognostic utility in PCI for patients with multi-vessel disease (MVD).

Spring-assisted cranioplasty (SAC) for the treatment of craniosynostosis uses internal springs to produce dynamic changes in cranial shape over several months before its removal. The purpose of this study was to report the first Egyptian experiences with SAC in the treatment of children with sagittal synostosis and evaluate the preliminary outcome. A total of 17 consecutive patients with scaphocephaly underwent SAC with a midline osteotomy along the fused sagittal suture and insertion of 3 springs with bayonet-shaped ends across the opened suture.

Megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a rare genetic form of cerebral white matter disease whose clinicoradiologic correlation has not been completely understood. In this study, we investigated the association between clinical and brain magnetic resonance imaging (MRI) features in 22 Egyptian children (median age 7 years) with MLC. Gross motor function was assessed using the Gross Motor Function Classification System, and evaluation of brain MRI followed a consistent scoring system.

Optimal treatment of cancer requires diagnostic methods to facilitate therapy choice and prevent ineffective treatments. Direct assessment of therapy response in viable tumor specimens could fill this diagnostic gap. Therefore, we designed a microfluidic platform for assessment of patient treatment response using tumor tissue slices under precisely controlled growth conditions.

Nephropathic cystinosis is a severe, monogenic systemic disorder that presents early in life and leads to progressive organ damage, particularly affecting the kidneys. It is caused by mutations in the CTNS gene, which encodes the lysosomal transporter cystinosin, resulting in intralysosomal accumulation of cystine. Recent studies demonstrated that the loss of cystinosin is associated with disrupted autophagy dynamics, accumulation of distorted mitochondria, and increased oxidative stress, leading to abnormal proliferation and dysfunction of kidney cells.

Background: Glutaric acidemia type 1 (GA1) is an inherited neurometabolic disease with significant morbidity. However, neuro-radiological correlation is not completely understood.

Objective: The study aimed to characterize the neuroimaging findings and their association with neurological phenotype in GA1 children.

Membrane transporters and receptors are responsible for balancing nutrient and metabolite levels to aid body homeostasis. Here, we report that proximal tubule cells in kidneys sense elevated endogenous, gut microbiome-derived, metabolite levels through EGF receptors and downstream signaling to induce their secretion by up-regulating the organic anion transporter-1 (OAT1). Remote metabolite sensing and signaling was observed in kidneys from healthy volunteers and rats in vivo, leading to induced OAT1 expression and increased removal of indoxyl sulfate, a prototypical microbiome-derived metabolite and uremic toxin.

Self-inflicted eye trauma is a serious form of self-harm as it may lead to irreversible visual disability. Diagnosing self-inflicted ocular injuries, in all its forms, can be quite challenging. In this report, we are presenting a 5-year-old girl presented to Sohag University Outpatient Clinic with a history of repeated attacks of bilateral eye redness with blood-tinged strands removed from her eyes.

Background: Autism is currently known as "a behaviorally defined syndrome" manifested as impairment in social communication, repetitive routines and restricted interests. There is an increased risk of ASDs associated with common mutations affecting the folate/methylation cycle.

Aim: The aim of this study was to identify C677T and 1298AC polymorphic genotypes of MTHFR gene among a sample of Egyptian children with autism and to make a phenotype-genotype correlation for the autistic patients.

Background: Resveratrol is a potential treatment option for management of non-alcoholic fatty liver disease (NAFLD) due to its anti-inflammatory, antioxidant properties, and calorie restriction-like effects. We aimed to synthesise evidence from published randomized clinical trials (RCTs) about the efficacy of resveratrol in the management of NAFLD.

Methods: A computer literature search of PubMed, Scopus, Web of Science, and Cochrane Central was conducted using relevant keywords.
