Background Herpes zoster is a common viral infection caused by reactivation of the varicella-zoster virus (VZV) characterized by the presence of a segmental distribution of painful grouped vesicles on an erythematous base. It is associated with several complications like zoster-associated pain (ZAP), postherpetic neuralgia (PHN), pigmentary changes, scarring, secondary infections, and dermatosis as well as severe systemic complications. Aims/objectives The aim of the study was to analyze the various clinical and epidemiological patterns of herpes zoster and post-herpetic complications. Materials and methods We conducted a single-center observational cross-sectional study on 72 patients with herpes zoster and post-herpetic complications attending the dermatology outpatient department (OPD) to understand its various clinical and epidemiological patterns. A detailed history taking regarding the onset, progression, and complications of the disease, as well as the type, duration, and severity of pain, was taken, followed by a general physical, systemic, and cutaneous examination, along with investigations wherever needed. Results A total of 72 patients were included in the study, comprising 32 (44.4%) patients suffering from herpes zoster and 40 (55.5%) patients suffering from post-herpetic complaints. The minimum age was 14 years, the maximum age was 83 years, and the mean age in our study was 52 ± 17 years. The most commonly affected age group was 41-60 years. A total of 52 males and 22 females were included in the study, resulting in a male-to-female ratio of 2.3:1. The thoracic dermatome was the most commonly involved dermatome, observed in 43 (59.7%) patients, and the left side was more commonly affected, seen in 41 (56.9%) patients. Among the total 72 patients, 26 (36.1%) had co-morbidities, with hypertension (18%) being the most common, followed by diabetes mellitus (12.5%). Regarding the post-herpetic complaints encountered in our study, the most common was post-herpetic neuralgia, seen in 31 (77.5%) patients, followed by post-herpetic pigmentation (macular), observed in 22 (55%) patients, and scarring (papules, plaques, hypertrophic scar, and keloid), observed in 17 (42.5%) patients. Conclusion A broader understanding of the clinical and epidemiological factors of herpes zoster and post-herpetic complications is important as this disease constitutes a considerable burden in a tertiary care center and if not treated adequately, the after-effects might last for many years altogether. Hence, early diagnosis and initiation of adequate antiviral therapy as well as pain management is the key aspect of management.

Introduction Herpes zoster (HZ) is a viral infection that occurs due to the reactivation of the varicella-zoster virus. The vaccination against herpes zoster to prevent its complications has been approved for individuals 50 years of age and older. This study aims to evaluate the knowledge, attitudes, and habits of at-risk populations about the varicella-zoster virus and its vaccination. Methodology A quantitative, observational, cross-sectional study was conducted among 500 adults over 50 years of age. Participants were selected by non-probability, convenience sampling from public places. RStudio (R version 4.1.1) was used to analyze the data. Result Eighty-three percent (n = 416) of participants had heard of herpes zoster (HZ). Seventy-four percent of respondents (n = 368) did not recognize the link between varicella and herpes zoster. Multiple linear regression showed that individuals who had varicella and heard about herpes zoster were the only positive predictors of herpes zoster knowledge. Out of all the respondents, 55.8% (n = 279) had heard of the herpes zoster vaccine, but 94.6% (n = 473) had not taken it. Among the respondents, 28.1% (n = 118) were unwilling to take optional vaccines; 77.4% (n = 387) agreed to take the HZ vaccine if recommended by a healthcare professional. Conclusion The general Saudi population had a good understanding of HZ and its vaccine. Their attitudes toward the HZ vaccine were generally positive; however, poor practices were observed. We recommend that arranging national campaigns targeting at-risk populations can enhance awareness about herpes zoster and its vaccine, subsequently increasing the rate of HZ immunization.

UNASSIGNED: The aim of the UVHER project is to evaluate the risk of development of optic nerve damage in patients with herpetic anterior uveitis (AU) prospectively followed over 2 years. Herein, we described the baseline characteristics.
UNASSIGNED: This is a multicentre, prospective study. An aqueous humour tap was performed. Only patients with a positive PCR were included. Clinical characteristics, optical coherence tomography (OCT) parameters and visual field (VF) abnormalities were registered.
UNASSIGNED: 27 patients were included: 18 Herpes Simplex (HSV), one Varicella Zoster (VVZ), and 8Cytomegalovirus (CMV). Patients with HSV-AU had severe inflammation, iris atrophy and corneal involvement. In patients with CMV-AU, less inflammation and medium-to-large keratic precipitates were observed. OCT showed a thinner RNFL and GCL in CMV-AU patients in comparison to HSV patients. VF showed abnormalities in six cases.
UNASSIGNED: Patients in the UVHER cohort showed the typical clinical manifestations of herpetic AU. In CMV patients, optic nerve damage was observed at baseline, and in HSV patients, inflammation was more severe.
