Introduction: Trigeminal neuralgia (TGN) poses a therapeutic challenge, particularly within the context of multiple sclerosis (MS). This study aimed to conduct a comprehensive meta-analysis and systematic review of four less-invasive treatment modalities for TGN in MS patients, namely, gamma knife radiosurgery (GKRS), glycerol rhizotomy (GR), balloon compression (BC), and radiofrequency ablation (RFA).

Methods: Single-armed meta-analyses were employed to assess the overall efficacy of each treatment, while double-armed analyses compared the efficacy between different treatment options in double-armed studies.

Objective: Sleep disturbances commonly reported among epilepsy patients have a reciprocal relationship with the condition; While epilepsy and anti-seizure medications (ASMs) can disrupt sleep structure, disturbed sleep can also exacerbate the frequency of seizures. This study explored subjective sleep disturbances and compared sleep profiles in patients who underwent ASM monotherapy and polytherapy.

Methods: We enrolled 176 epilepsy patients who completed a structured questionnaire containing demographic and clinical information and the Persian versions of the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), and Patient Health Questionnaire-9 (PHQ-9) to evaluate sleep quality, insomnia, excessive daytime sleepiness (EDS), and depressive symptoms, respectively.

Development of novel low-cost readout electronics for large field-of-view gamma camera detectors.

Phys Med

May 2024

Research Center for Molecular and Cellular Imaging (RCMCI), Advanced Medical Technologies and Equipment Institute (AMTEI), Tehran University of Medical Sciences (TUMS), Tehran, Iran; Department of Medical Physics and Biomedical Engineering, Tehran University of Medical Sciences, Tehran, Iran. Electronic address:

Purpose: Large scintillation crystals-based gamma cameras play a crucial role in nuclear medicine imaging. In this study, a large field-of-view (FOV) gamma detector consisting of 48 square PMTs developed using a new readout electronics, reducing 48 (6 × 8) analog signals to 14 (6 + 8) analog sums of each row and column, with reduced complexity and cost while preserving image quality.

Methods: All 14 analog signals were converted to digital signals using AD9257 high-speed analog to digital (ADC) converters driven by the SPARTAN-6 family of field-programmable gate arrays (FPGA) in order to calculate the signal integrals.

Glycogen storage diseases (GSDs) are a group of rare inherited metabolic disorders characterized by clinical, locus, and allele heterogeneity. This study aims to investigate the phenotype and genotype spectrum of GSDs in a cohort of 14 families from Iran using whole-exome sequencing (WES) and variant analysis. WES was performed on 14 patients clinically suspected of GSDs.

Telovelar vs. Transvermian approach for the fourth ventricle tumors: A systematic review and meta-analysis.

Clin Neurol Neurosurg

May 2024

Centre for Minimally Invasive Neurosurgery, Sydney, Australia; Department of Neurosurgery, NUH, Singapore, Singapore; Department of Neurosurgery, FJD University Hospital, Madrid, Spain; Department of Neurosurgery, Hanoi Medical University, Viet Nam. Electronic address:

Background: Tumors in the fourth ventricle can be critical due to the small size of the fourth ventricle, which causes symptoms to be detected even in the presence of lesser mass effects. A proper surgical approach to the fourth ventricle poses challenges due to its deep location and proximity to vital compartments within the brainstem. The two commonly used approaches to these tumors are the transvermian and telovelar approaches.

Background: There is controversial data on the effects of prebiotic, probiotic, or synbiotic supplementations on overweight/obesity indicators. Thus, we aimed to clarify this role of biotics through an umbrella review of the trials' meta-analyses.

Methods: All meta-analyses of the clinical trials conducted on the impact of biotics on overweight/obesity indicators in general populations, pregnant women, and infants published until June 2023 in PubMed, Web of Sciences, Scopus, Embase, and Cochrane Library web databases included.

Background: Given the limited specificity of D-dimer, there is a perceived need to discover a more precise marker for diagnosing individuals who are suspected of having pulmonary embolism (PE). In this study, by evaluating the increase in the serum level of Apelin-13 and D-dimer, we found valuable findings about Apelin-13, which can be suggested as an auxiliary and non-invasive diagnostic biomarker in individuals with suspected PE, based on the obtained results.

Methods: In this case-control study, 52 Iranian individuals were included, all of whom were suspected to have PE.

  • The study investigated the prevalence and effects of Caffeine Use Disorder (CUD) and caffeine consumption among 1,228 adults in Iran, finding significant rates of both conditions.
  • Results revealed that 19.5% of participants had CUD and 46.62% experienced caffeine withdrawal, with higher prevalence in men compared to women.
  • The study highlighted common caffeine-related harms such as cravings for sugar, insomnia, and dependence, indicating a need for evidence-based treatments for managing caffeine use issues in the Iranian population.

One of the goals of the HORIZON 2020 project PoCOsteo was to develop a medical device, which would measure and/or quantify proteomic as well as genomic factors as present in whole blood samples collected through finger prick. After validating the tool in the clinical setting, the next step would be its clinical validation based on the existing guidelines. This article presents the protocol of a validation study to be carried out independently at two different centers (Division of Endocrinology and Diabetology at the Medical University of Graz as a clinic-based cohort, and the Endocrinology and Metabolism Research Institute at the Tehran University of Medical Sciences as a population-based cohort).

Background: Among neurological diseases, multiple sclerosis (MS) affects mostly young adults and can cause long-term disability. While most medications with approval from regulatory agencies are very effective in treating MS disease, they are unable to repair the tissue damage found in the central nervous system (CNS). Consequently, Cell-based therapy particularly using mesenchymal stem/stromal cells (MSCs), holds promise for neuroprotection and tissue repair in MS treatment.

Article Synopsis
  • The study addresses the issue of partial volume effects in PET imaging, which significantly impact image quality and accuracy due to the technology's limited resolution.
  • Researchers developed a deep learning framework using a modified U-Net model to predict partial volume corrected full-dose images from standard or low-dose PET images, without needing anatomical data.
  • Evaluation of their method showed varying error levels among different correction techniques, with the proposed framework successfully improving the denoising and correction processes for both low and full-dose PET images.

Major depressive disorder (MDD) is an increasingly common psychiatric illness associated with a high risk of insufficient physical activity, which in turn is associated with negative mental and physical health outcomes. Theory-based, individually tailored, in-person and remote physical activity counseling has the potential to increase physical activity levels in various populations. Given this, the present study investigated the effect of such a physical activity intervention on the physical activity behavior of in-patients with MDD.

Background And Aims: The occurrence of thiamine metabolism dysfunction syndrome (THMD), a rare autosomal recessive condition, may be linked to various mutations found in the and genes. The disease chiefly manifests through ataxia, muscle hypotonia, abrupt or subacute onset encephalopathy, and a decline in developmental milestones achieved during the early stages of infancy. We present findings from an investigation that involved two individuals from Iran, both of whom experienced seizures along with ataxia and hypotonia.

Acute lymphoblastic leukemia (ALL) is a life-threatening disease that commonly affects children and is classified into three subtypes: L1, L2, and L3. Traditionally, ALL is diagnosed through morphological analysis, involving the examination of blood and bone marrow smears by pathologists. However, this manual process is time-consuming, laborious, and prone to errors.
