To investigate the seroprevalence of Herpes Simplex Viruses (HSV1 and HSV2), Ebstein-Barr Virus (EBV) and Hepatitis B Virus (HBV) in children with acute lymphoblastic leukemia (ALL) in southern Iran. 90 patients with ALL and 90 age-sex matched healthy participants were enrolled in this study. Antibodies (IgG) against HBsAg, HSV1, HSV2, EBV different antigens including Epstein-Barr nuclear antigen-1 (EBNA-1), viral capsid antigen (VCA) and early antigen (EA) were measured by enzyme-linked immunosorbent assay (ELISA). There were 54 (60%) male and 36 (40%) female in both study groups with mean age of 8.47 ± 3.61 and 8.61 ± 2.84 years in case and control group respectively (P = 0.812). The prevalence of antibodies against HBsAg (P = 0.002), HSV1 (P < 0.0001), VCA (P = 0.021) and EA (P < 0.0001) antigens of EBV were significantly higher in ALL patients. With the results of this study, we could not exclude a connection between these viral infections and later leukemogenesis in childhood ALL, although nor latent infection nor congenital infection cannot be excluded by this method.

Background: Neurologic symptoms seen in patients receiving immune checkpoint inhibitors (ICI) may not be entirely caused by immunotoxicity. We aim to highlight these confounding conditions through clinical cases to encourage early recognition and management.

Methods: We describe a series of seven cases from our institution that were treated with ICI and presented with Neurologic symptoms and were diagnosed with superimposed conditions beyond immunotoxicity.

Background: Human papillomavirus (HPV) is a leading cause of cervical cancer, with 14 subtypes classified as high-risk human papillomavirus (HR-HPV). Despite the availability of vaccines, certain regions still experience limited access. Herpes simplex virus type II (HSV-II), a common sexually transmitted infection, is hypothesized to increase the risk of HR-HPV infections.

Introduction: The Behçet's Disease Current Activity Form (BDCAF) is crucial for monitoring the progression and treatment efficacy of Behçet's Disease (BD), an autoimmune disorder that can be triggered or exacerbated by viral infections. Herpes simplex virus type 1 (HSV-1) has long been recognized as a potential trigger for BD, as it can induce systemic inflammation and exacerbate symptoms. In contrast, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has recently emerged and may also initiate or worsen BD symptoms.

Department of Psychology, Neuroscience Program, University of Nebraska Omaha, Omaha, NE 68182-0001, USA.

Supplementing textbooks with primary literature in teaching neuroscience is a growing practice associated with several positive outcomes, such as increased content knowledge, research and data skills, and critical thinking. This pedagogical approach, however, still needs further development to make it accessible to instructors and valuable to students. This article describes a series of published articles we used in an undergraduate neuroimmunology course.
