The autism spectrum disorder (ASD) registry program presents a unique opportunity to facilitate advanced research in various aspects of ASD, particularly in low-resource countries like Iran. Given the international significance of autism research, registry programs play a critical role in data sharing. ASD registry programs have been effectively established in high-income countries over a few decades; however, there are limited examples from low- and middle-income countries.

Objectives: Given that deficiency in B vitamins can lead to the accumulation of homocysteine (Hcy), and hyperhomocysteinemia may have a role in migraine pathogenesis, the present prospective randomized double-blinded placebo-controlled trial aimed to evaluate the effect of vitamin B-complex supplementation on the alleviation of migraine in children through a possible reduction in Hcy levels.

Materials & Methods: Ninety children under 15 years of age suffering from typical migraine were included in the present trial. They were randomly assigned into two groups (forty-five patients in each group) to receive either vitamin B-complex or a matching placebo for six months.

Article Synopsis
  • Leukodystrophies (LDs) are neurological disorders affecting the white matter of the brain, and this study focuses on creating an Iranian LD Registry to analyze the clinical and genetic data of Persian patients.
  • From 680 patients registered between 2016-2019, 342 underwent diagnostic evaluations, with 245 ultimately diagnosed—24.5% in a hypomyelinating LD group and the rest in other categories.
  • Genetic testing revealed causal variants in 228 patients, with whole-exome sequencing (WES) being more effective (60.7% diagnostic rate) than single gene testing; lysosomal disorders were the most prevalent diagnoses.

Congenital fibre-type disproportion (CFTD) with myopathy, is a genetically heterogeneous disease in which there is relative hypotrophy of type-1-muscle-fibres compared to type-2-fibres on skeletal muscle biopsy. The classical characteristics of CFTD are infantile hypotonia and nonprogressive muscle weakness with a broad range of clinical manifestations. Pathogenic mutations in the gene encoding 3-hydroxyacyl-CoA-dehydratase-1 have recently been reported to be associated with this disease.

In recent years, massively parallel sequencing or next generation sequencing (NGS) has considerably changed both the research and diagnostic fields, and rapid developments have led to the combination of NGS techniques in clinical practice, ease of analysis, and detection of genetic mutations. This article aimed at reviewing the economic evaluation studies of the NGS techniques in the diagnosis of genetic diseases. In this systematic review, scientific databases (PubMed, EMBASE, Web of Science, Cochrane, Scopus, and CEA registry) were searched from 2005 to 2022 to identify the related literature on the economic evaluation of NGS techniques in the diagnosis of genetic diseases.

The exact mechanism of a ketogenic diet (KD) as a suitable alternative therapeutic approach for drug-resistant epilepsy (DRE) in alleviating seizures is not yet fully understood. The present study aimed to evaluate the role of the KD in reducing oxidative stress (OS) by increasing the ketone body beta-hydroxybutyrate (BHB) and Arachidonic acid (ARA), an essential polyunsaturated fatty acid, as a possible mechanism in relieving seizure attacks in children with DRE. Forty children with refractory epilepsy were included in the present study.

Introduction: Dapagliflozin, a new treatment option for heart failure, leads to a significant reduction in the hospitalization of patients with heart failure. We aimed to review studies on the economic evaluation of adding dapagliflozin to standard care compared with standard care alone in heart failure patients with reduced ejection fraction (HFrEF).

Methods: For this systematic review, the PubMed, EMBASE, Web of Science, Cochrane, Scopus, and CEA Registry scientific databases were searched from 1 January 2020 to 25 March 2022.

Background: The implementation of follow-up programs for high-risk infants and toddlers aimed to promptly diagnose developmental delays and disorders and initiate early intervention to help improve their developmental status, reduce their care costs in the future, as well as improve their productivity as members of society. There is a lack of qualified specialists in the infant and toddler development field in Iran. To compensate for the lack of training in this area, for the first time, Tabriz University of Medical Sciences has designed a short-term supplementary course of "Developmental Care for Infants and Toddlers".

Acute flaccid myelitis (AFM) is an acute condition occurring mostly in children. Although affected patients can show a broad spectrum of symptoms, it is mainly characterized by the progressive onset of focal limb weakness, presenting over a period of hours to a week, with or without pain, and spinal cord gray matter involvement on magnetic resonance imaging (MRI). There is compelling evidence to support the role of viruses, in particular enteroviruses.

Objective: Subependymal Giant Cell Astrocytomas (SEGAs) are slow-growing glioneuronal tumors typically found around the ventricles of the brain, particularly near the foramen of Monro in 15%-20% of patients with tuberous sclerosis complex (TSC). Surgical resection is the standard treatment for these symptomatic tumors. The mTOR inhibitor everolimus can be regarded as an alternative treatment for SEGAs due to the complications of surgery.
