Background: Herpes zoster is one of the most common diseases in middle and old ages, and the incidence rate is constantly increasing. Long-term, severe neuropathological pain continues to afflict the patients, causing trouble and even the inability to live a normal life. Since the occurrence and development of herpes zoster are related to many mechanisms, there is no uniform conclusion and specific treatment method, and only a limited number of people are currently vaccinated against HZ.
Objective: This study aimed at exploring the potential mechanism or biomarkers for Herpes zoster.
Methods: In this study, a data set GSE165112 containing 12 samples was downloaded, out of which, 6 samples were treated with interferon, and 6 samples were not treated. Differentially expressed genes (DEG) analysis, KEGG, GO enrichment analysis, and GSEA were carried out.
Results: A total of 264 DEGs were identified, including 32 uP-regulated DEGs and 232 downregulated DEGs. DEGs are mainly enriched in immune response, inflammatory response, chemotaxis, etc. Four key pathways were found to be related to HZ, including IL2-STAT5 signaling, inflammatory response, TNF-a signaling via NF-κB, and IFN-α. Moreover, ten hub genes were also identified.
Conclusion: This study shows that exploring DEGs and pathways through bioinformatics analysis is of great significance for understanding the molecular mechanism of HZ, especially the defect of the IFN pathway. It may be helpful in improving the treatment for HZ.

The Société de Pathologie Infectieuse de Langue Française released in 2024 a new national recommendation for clinical practice on the prevention and management of varicella zoster virus (VZV) infection during pregnancy and the perinatal period. The previous recommendation was issued in 1998, at a time of anti-VZV immunoglobulins shortage; it has hence become obsolete. This recommendation is a formalized expert consensus focusing on infectious diseases management; it is drawn up by a multidisciplinary working group (infectiologists, obstetricians, pediatricians, microbiologists, midwives, hygienists).

Aim: Some countries are hesitant to implement routine varicella vaccination for children because of concerns over the exogenous boosting hypothesis, which suggests that vaccinating children may increase herpes zoster cases in adults. However, substantial evidence supporting this hypothesis is lacking. This study assessed the association between a child's varicella vaccination status and herpes zoster occurrence in adults in the same household.

Shingles, also known as herpes zoster, is a reactivation of the chickenpox virus that causes a painful, blistering rash. After a chickenpox infection, the virus lies dormant in nerve cells. When reactivated, usually in older adults or those with weakened immune systems, it travels along nerves, typically affecting a single strip of skin called a dermatome.

Introduction: The erector spinae plane block (ESPB) is a relatively new regional anesthetic procedure that provides analgesia below the erector spinae muscles in an interfascial plane. The indications for its use continue to expand as we learn more about this block.
Case: We report a case of a 60 year old woman presenting to the emergency department (ED) with severe intractable pain after recent onset of herpes zoster infection.
