Herpes Zoster Ophthalmicus Discovered During Pain Consult Possibly Complicated With Dural Sinus Thrombosis and Refractory Headache Managed With Ketamine: A Case Report
In this report, we present the case of a 51-year-old male with severe headache and imaging findings of dural sinus thrombosis. He was later diagnosed with herpes zoster ophthalmicus and required aggressive inpatient management of neuropathic pain. Despite appropriate treatment, acute herpes zoster can progress to post-herpetic neuralgia, requiring long-term pain management.PMID:37593290 | PMC:PMC10430885 | DOI:10.7759/cureus.42018

Investigation of Neurological Complications after COVID-19 Vaccination: Report of the Clinical Scenarios and Review of the Literature
Vaccines (Basel). 2023 Feb 13;11(2):425. doi: 10.3390/vaccines11020425.ABSTRACTCoronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), broke out in 2019 and became a pandemic in 2020. Since then, vaccines have been approved to prevent severe illness. However, vaccines are associated with the risk of neurological complications ranging from mild to severe. Severe complications such as vaccine-induced immune thrombotic thrombocytopenia (VITT) associated with acute ischaemic stroke have been reported as rare complications post-COVID-19 vaccination. During the pandemic era, V...

Zoster-associated Prothrombotic Plasma Exosomes and Increased Stroke Risk
J Infect Dis. 2022 Oct 6:jiac405. doi: 10.1093/infdis/jiac405. Online ahead of print.ABSTRACTHerpes zoster (HZ, shingles) caused by varicella zoster virus (VZV) reactivation increases stroke risk for up to one-year post-HZ. The underlying mechanisms are unclear, however, the development of stroke distant from the site of zoster (e.g. thoracic, lumbar, sacral) that can occur months after resolution of rash points to a long-lasting, virus-induced soluble factor(s) that can trigger thrombosis and/or vasculitis. Herein, we investigated the content and contributions of circulating plasma exosomes from HZ and non-HZ patient samp...

What Causes Microcephaly?
Discussion Microcephaly is usually defined as an occipitofrontal head circumference (OFC) more than 2 standard deviations (SD) below the mean for sex, age and ethnicity. Severe microcephaly is used for OFC < 3 standard deviations. Rates of microcephaly range from 0.5-12 patients/10,000 live births. The OFC should be measured at every well child visit and at other opportunities and plotted on standard growth charts. The OFC is measured using a nonelastic tape measure around the largest part of the head with the tape measure held above the eyebrows and ears. It is a highly reproducible measurement. There are several diff...

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54] Hippocampus relays information about contextual information based on past experiences and the current situat...
