Common Features Between Stroke Following Varicella in Children and Stroke Following Herpes Zoster in Adults : Varicella-Zoster Virus in Trigeminal Ganglion
Curr Top Microbiol Immunol. 2021 Jul 6. doi: 10.1007/82_2021_236. Online ahead of print.ABSTRACTThe cerebral arteries are innervated by afferent fibers from the trigeminal ganglia. Varicella-zoster virus (VZV) frequently resides in the trigeminal ganglion. Reports of arterial ischemic stroke due to VZV cerebral vasculopathy in adults after herpes zoster have been described for decades. Reports of arterial ischemic stroke due to post-varicella cerebral arteriopathy in children have also been described for decades. One rationale for this review has been post-licensure studies that have shown an apparent protective effect fro...

Herpes simplex virus 2 vasculitis as cause of ischemic stroke in a young immunocompromised patient
We report a case of a young woman with a left middle cerebral artery (MCA) ischemic stroke. The patient had history of HIV-1 infection, with periods of therapeutic non-compliance. Initial computed tomography (CT) imaging studies showed stenosis of the M1 segment of the left MCA, and magnetic resonance imaging (MRI) confirmed infarction of the MCA territory. Serial transcranial Doppler ultrasound revealed progressive occlusion of the MCA and stenosis of the left anterior cerebral artery. Systemic investigation for other causes of stroke was normal. Lumbar puncture revealed a mildly inflammatory cerebrospinal fluid, and HSV-...

Zoster sine herpete: a review.
Authors: Zhou J, Li J, Ma L, Cao S Abstract Zoster sine herpete (ZSH) is one of the atypical clinical manifestations of herpes zoster (HZ), which stems from infection and reactivation of the varicella-zoster virus (VZV) in the cranial nerve, spinal nerve, viscera, or autonomic nerve. Patients with ZSH display variable symptoms, such as neuralgia, however, different from HZ, ZSH show no zoster, which makes clinical diagnosis difficult. ZSH not only causes initial symptoms, such as neuropathic pain in the affected nerve, Bell palsy, and Ramsay Hunt syndrome, but also postherpetic neuralgia and fatal complications suc...

Mediation effect of herpes zoster derived by statin use on cardiovascular disease risk.
Conclusions: This study showed that statin use reduced CVD by 10%, but the protective effect of statin use against CVD was mitigated by approximately 10% through the development of HZ caused by statin use. PMID: 32550721 [PubMed - as supplied by publisher]

Unusual Symptoms of Coronavirus: What We Know So Far
While most people are familiar with the hallmark symptoms of COVID-19 by now—cough, fever, muscle aches, headaches and difficulty breathing—a new crop of medical conditions are emerging from the more than 4 million confirmed cases of the disease around the world. These include skin rashes, diarrhea, kidney abnormalities and potentially life-threatening blood clots. It’s not unusual for viruses to directly infect and affect different tissues and organs in the body, but it is a bit unusual for a primarily respiratory virus like SARS-CoV-2, which is responsible for COVID-19, to have such a wide-ranging reach...

Prevalence of herpesviruses in periodontal disease of the North Indian population: A pilot study
Conclusions: Within the limitation of this study, EBV was found in cases of periodontitis patients. Its role in disease initiation and progression is not clear. Further studies are required to ascertain EBV as risk factor in periodontal disease.

Transcutaneous Electrical Nerve Stimulation in Relieving Neuropathic Pain: Basic Mechanisms and Clinical Applications
AbstractPurpose of ReviewTranscutaneous electrical nerve stimulation (TENS) is widely used as a non-pharmacological approach for pain relief in a variety of clinical conditions. This manuscript aimed to review the basic mechanisms and clinical applications regarding the use of TENS for alleviating the peripheral (PNP) and central neuropathic pain (CNP).Recent FindingsBasic studies on animal models showed that TENS could alleviate pain by modulating neurotransmitters and receptors in the stimulation site and its upper levels, including the spinal cord, brainstem, and brain. Besides, many clinical studies have investigated t...

Adult onset MELAS Syndrome Presenting as A Mimic of Herpes Simplex Encephalitis.
CONCLUSION: The clinical presentation and imaging studies of MELAS in adults are variable and may mimic those of HSE. Antiviral therapy should be administered until the diagnosis of MELAS is definitive. Infection and metformin may have also precipitated MELAS manifestation in this patient. Clinicians should avoid potential mitochondrial-toxic drugs in these patients. PMID: 31867706 [PubMed - in process]

Bihemisphere Ischemia Due to a Unilateral Lesion: A Case Report
We present the case of a 70-year-old man with multiple acute/subacute bilateral infarcts. The patient was found to have stenosis of the left internal carotid artery secondary to herpes zoster ophthalmicus vasculopathy, with involvement of the left proximal middle and anterior cerebral arteries. Angiographic studies also revealed A1 segment aplasia of the right anterior cerebral artery (ACA), thus indicating dependence on the left-sided circulation for perfusion of the bilateral ACA vascular territory.

Vascular Event Risk After Herpes Zoster
We have read the article by Patterson et  al1 published in the April 2019 issue of Mayo Clinic Proceedings. The authors performed an interesting study using propensity score to evaluate the cardiovascular disease risk during the prodromal period and aggregate period of herpes zoster (HZ) infection. The incidence rate calculated according to the time line before and after the index date also provided valuable information on the following cardiovascular risk. Evidence from large population-based studies suggests a transiently increased risk of stroke after HZ.
