Article Abstract
Leukodystrophies are a number of rare genetic disorders that influence the white matter of the brain. The current study aimed to identify the underlying genetic cause of leukodystrophy in 14 Iranian cases, mainly presented by hypomyelinating leukodystrophies. Whole exome sequencing was used for this purpose. Notably, a certain RARS1 variant (c.2T > C) was found in six cases. In addition, six cases carried homozygote variants in the GJC2, PLEKHG2, RNF220, POLR1C, DEGS1 and ACER3 genes, respectively. Finally, two patients carried a heterozygote variant in TMEM63A or TUBB4A, respectively. Taken together, the current study shows high prevalence of a certain RARS1 variant among Iranian patients with leukodystrophy. Moreover, a list of other genes was suggested as underlying causes of leukodystrophy in this population. Further studies are needed to elaborate the spectrum of genetic mutations in Iranian cases with leukodystrophy.

Background: Healthcare-associated infections (HCAIs) pose a serious threat to healthcare systems. Accurately determining the incidence of HCAIs is crucial for planning and implementing efficient interventions, as they are associated with a wide range of challenges. The objective of this study was to assess and update the incidence rates of HCAIs in Iran in 2023, using data from the Iranian Nosocomial Infection Surveillance (INIS) system, a nationwide hospital-based surveillance program.

Background: In Iran, efforts have been made to integrate medical education and the health system with the aim of promoting social responsiveness. Despite these efforts, there is still room for improvement in this process. To gain a better understanding of this topic, a study was carried out to gather insights from experts on the integration of medical education in the Iranian health system.

The purpose of this study was to evaluate the effect of local anesthesia (LA) for dental treatment of children under general anesthesia (GA) on physiologic parameters of patients and recovery of the patients. This information is important because currently, no guidelines exist to define the usage of local anesthetics in dental cases under GA. This study was designed as a double-blinded randomized clinical trial.

This study compares three hereditary colorectal cancer (CRC) registries-the Iranian Hereditary Colorectal Cancer Registry (IHCCR), the Singapore Polyposis Registry (SPR), and the University of Cape Town Familial CRC Registry-to illuminate diverse approaches to identification, management, and research across different healthcare systems. Each registry, while emphasizing patient diversity, employed unique strategies reflecting available resources and epidemiological contexts. The IHCCR, leveraging WES, revealed considerable genetic heterogeneity, including novel mutations.
