Segmental Zoster Paresis: A Literature Review.

Pain Physician 2021 May;24(3):253-261

Department of Anesthesiology, Ruijin Hospital of Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Background: Herpes zoster is an acute infectious skin disease that is induced by the re-activation of the virus incubated in nerve ganglions following initial infection with varicella-zoster virus in childhood. Herpes zoster mainly affects sensory nerves, resulting in severe acute pain, which is also the most common reason for medical intervention in this patient group. The concurrent involvement of motor nerves could induce the symptoms of segmental zoster paresis, which is manifested by localized asymmetric myasthenia, whose range generally follows the distribution of myomere with skin rashes.

Efficacy of Pulsed Radiofrequency or Short-Term Spinal Cord Stimulation for Acute/Subacute Zoster-Related Pain: A Randomized, Double-Blinded, Controlled Trial.

Pain Physician 2021 May;24(3):215-222

Department of Pain Medicine, The First Affiliated Hospital of China Medical University, Shenyang City, China.

Background: Postherpetic neuralgia (PHN) is the final stage of varicella zoster infection and a severe refractory neuropathic pain. Hence preventing transition of herpes zoster-related pain to PHN is a very important therapeutic principle for patients at an early stage, especially for older patients.Both pulsed radiofrequency (PRF) and short-term spinal cord stimulation (stSCS) have been proven to be effective to relieve acute/subacute zoster-related pain.

Varicella Zoster Meningitis in Immunocompetent Hosts: A Case Series and Review of the Literature.

WMJ 2021 Apr;120(1):74-77

Department of Medicine, Medical College of Wisconsin, Milwaukee, Wisconsin.

Meningitis caused by varicella zoster virus (VZV) infection is uncommon in immunocompetent patients. We report 3 cases of VZV meningitis with rash in immunocompetent adults from a single academic institution over a 1-year period. The low prevalence of VZV meningitis in this population is attributed to lack of early recognition or underreporting. Read More

Fostering healthy aging: the interdependency of infections, immunity and frailty.

Ageing Res Rev 2021 May 7:101351. Epub 2021 May 7.

Aging Research Center, Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, Stockholm, Sweden; Stockholm Gerontology Research Center, Stockholm, Sweden.

Untangling the interdependency of infections, immunity and frailty may help to clarify their roles in the maintenance of health in aging individuals, and the recent COVID-19 pandemic has further highlighted such priority. In this scoping review we aimed to systematically collect the evidence on 1) the impact of common infections such as influenza, pneumonia and varicella zoster on frailty development, and 2) the role played by frailty in the response to immunization of older adults. Findings are discussed under a unifying framework to identify knowledge gaps and outline their clinical and public health implications to foster a healthier aging. Read More

Exp Clin Transplant 2021 May 6. Epub 2021 May 6.

From the Department of General Surgery, Post Graduate institute of Medical Education & Research, Chandigarh, India.

Guillain-Barre syndrome is an acute immune-mediated demyelinating, polyneuropathy, which is usually provoked by a preceding infection. Guillain-Barre syndrome lies within the spectrum of disimmune neuropathies and usually occurs in immunocompromised patients because it is theoretically contradictory. Guillain-Barre syndrome in liver transplant recipients has been rarely reported. Read More

Granuloma annulare - is it a paraneoplastic condition for malignant lymphoma?

J Dtsch Dermatol Ges 2021 May 5. Epub 2021 May 5.

Department of Dermatology, Allergology and Venereology, Saarland University Hospital, Homburg/Saar.

In recent years, an association between granuloma annulare and the occurrence of malignant cutaneous lymphomas in the sense of a facultative paraneoplasia has been observed several times. The aim of the present work is to provide an overview of the currently available literature on granuloma annulare as well as an analysis of its association with cutaneous lymphomas. Using the example of two patients with granuloma annulare and associated cutaneous lymphomas, we would like to sensitize clinically active dermatologists and dermatopathologists to the possible association between these two diseases.

Interplay of Anti-Viral Vaccines with Biologic Agents and Immunomodulators in Individuals with Autoimmune and Autoinflammatory Diseases.

Immunol Invest 2021 May 3:1-24. Epub 2021 May 3.

Departments of Microbiology & Immunology, Medicine and Pathology, Jacobs School of Medicine and Biomedical Sciences, SUNY at Buffalo, Buffalo, New York, USA.

Vaccines are an essential part of a preventative healthcare strategy. However, response to vaccines may be less predictable in immunocompromised people. While outcomes for individuals with autoimmune and autoinflammatory diseases have dramatically improved with treatment using immunomodulating and biologic agents, infections have caused significant morbidity in these people today often more than due to their underlying diseases.

1Institut Pasteur de Dakar, Unité de Virologie Médicale, Dakar, Sénégal.

Herpesviruses are known to cause a diversity of clinical syndromes, ranging from minor cutaneous lesions to life-threatening illnesses, especially in immunocompromised hosts. Here, we investigate retrospectively the contribution of five human herpesviruses, including herpes simplex virus Cytomegalovirus (CMV), the Epstein-Barr virus (EBV), human herpesvirus 6, and varicella zoster virus (VZV) in serum samples collected from measles suspected patients with at least fever and rash. Sera specimens were first tested for serological evidence of measles and rubella virus infection by ELISA, and DNA extracted from an aliquot of each clinical specimen for molecular detection of human herpes viruses by RT-qPCR.

Vessel wall MR imaging of central nervous system vasculitis: a systematic review.

Neuroradiology 2021 May 3. Epub 2021 May 3.

Department of Radiology, Hospital of the University of Pennsylvania, 3400 Spruce Street, Philadelphia, PA, 19104, USA.

Purpose: Beyond vessel wall enhancement, little is understood about vessel wall MR imaging (VW-MRI) features of vasculitis affecting the central nervous system (CNS). We reviewed vessel wall MR imaging patterns of inflammatory versus infectious vasculitis and also compared imaging patterns for intracranial versus extracranial arteries of the head and neck.

Methods: Studies reporting vasculitis of the CNS/head and neck and included MR imaging descriptions of vessel wall features were identified by searching PubMed, Scopus, Cochrane, Web of Science, and EMBASE up to June 10, 2020. Read More

Current Immunological and Clinical Perspective on Vaccinations in Multiple Sclerosis Patients: Are They Safe after All?

Int J Mol Sci 2021 Apr 8;22(8). Epub 2021 Apr 8.

Division of Neurochemistry and Neuropathology, Department of Neurology, Poznan University of Medical Sciences (PUMS), 60-355 Poznań, Poland.

Vaccines work by stimulating the immune system, and their immunogenicity is key in achieving protection against specific pathogens. Questions have been raised whether in Multiple Sclerosis (MS) patients they could induce disease exacerbation and whether vaccines could possibly act as a trigger in the onset of MS in susceptible populations. So far, no correlation has been found between the vaccinations against influenza, hepatitis B, tetanus, human papillomavirus, measles, mumps, rubella, varicella zoster, tuberculosis, yellow fever, or typhoid fever and the risk of MS.
