Abdominal pain is one of the most common presenting chief complaints in the emergency department (ED). Erector spinae plane block (ESPB) is an ultrasound-guided nerve block with proven effectiveness in treating visceral and somatic abdominal pain. Despite the increasing popularity of ESPB, its role in the management of non-surgical abdominal pain has not yet been characterized. Our scoping review aims to review the current literature on the safety and efficacy of ESPB in the management of patients experiencing intractable, non-surgical abdominal pain...

PURPOSE: To assess the risk of gonioscopy-assisted transluminal trabeculotomy (GATT) inducing an uveitic flare-up in patients with uveitic glaucoma (UG). METHODS: This retrospective study included consecutive UG patients who underwent GATT at a single medical center between June 2020 and September 2022. The main outcome measure was the occurrence of a surgery-related uveitic complication defined as either an uveitic flare-up defined by the Standardization of Uveitis Nomenclature (SUN) criteria, or the appearance of cystoid macular edema (CME) from 2 weeks to 3 months after surgery...

INTRODUCTION: Infectious Keratitis is one of the most common ocular emergencies seen by ophthalmologists. Our aim is to identify the risk factors and clinical features of Acanthamoeba Keratitis (AK). METHODS: This retrospective chart review study was conducted at King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia, and included all the microbial keratitis cases, male and female patients of all ages. The main outcome is the differentiation between various microbial keratitis types...

BACKGROUND: Herpes zoster (HZ) is a reactivation of the varicella-zoster virus (VZV) that can occur in people with weakened immune systems. Chronic obstructive pulmonary disease (COPD) is a chronic lung disease that can also impair the immune system.6-8. CASE PRESENTATION: The authors present the case of a 65-year-old male with COPD who developed HZ. The patient was initially admitted to the hospital for an acute exacerbation of COPD. After his condition stabilized, he developed vesicular rashes on the medial aspect of his left leg...

PURPOSE: This article presents the first clinical results of intravital morphological verification of epithelial and stromal keratitis associated with betaherpesviruses. MATERIAL AND METHODS: The study group included 12 patients (12 eyes) diagnosed with herpetic keratitis. During the initial visit to the clinic, each patient underwent a standard ophthalmological examination, as well as a number of laboratory tests: immunochemical analysis of blood, molecular diagnostics, and confocal microscopy...

Herpetic uveitis is an easy diagnosis to miss, which can lead to devastating consequences. The aim of this report is to create awareness of how this disease can present, appropriate clues to the diagnosis, and how it should be managed. We report a case of a 70-year-old female who presented with redness and painless blurry vision in her right eye and was treated with topical corticosteroid drops for presumed idiopathic anterior uveitis. Despite initial symptomatic improvement, she reattended with a significant deterioration in vision and was found to have a large corneal infiltrate and associated perforation...

PURPOSE: Uveitis-Glaucoma-Hyphema (UGH) syndrome results from contact between the intraocular lens (IOL) and the iris or ciliary body, leading to uveal structure erosion and blood-aqueous barrier breakdown. Treatment involves various drugs, with IOL removal often being necessary. Diagnosis relies on clinical signs, but imaging techniques like ultrasound biomicroscopy (UBM) or anterior segment optical coherence tomography (AS-OCT) are crucial. AS-OCT accurately depicts IOL position and potential contact, emerging as a primary alternative to UBM in the diagnosis...

PURPOSE: Chronic inflammation is a predisposing factor for metaplastic changes and ultimately dysplasia. We describe cases of OSSN occurring in the setting of chronic ocular surface inflammation. METHODS: Sixteen eyes from 14 individuals were included from one ocular oncology clinic between 2010 and 2023. Patients presented with ocular surface squamous neoplasia (OSSN) in the setting of chronic inflammation. The diagnosis of OSSN was made using anterior segment high-resolution optical coherence tomography (HR-OCT) and confirmed by histopathological analysis in all cases...

Postherpetic neuralgia (PHN) is a notorious neuropathic pain featuring persistent profound mechanical hyperalgesia with significant negative impact on patients' life quality. CDDO can regulate inflammatory response and programmed cell death. Its derivative also protects neurons from damages by modulating microglia activities. As a consequence of central and peripheral sensitization, applying neural blocks may benefit to minimize the risk of PHN. This study aimed to explore whether CDDO could generate analgesic action in a PHN-rats' model...

INTRODUCTION: Herpes zoster (HZ; shingles) is a painful, cutaneous disease caused by reactivation of the varicella zoster virus, which causes varicella (chickenpox) typically during childhood. The considerable healthcare burden of HZ is relatively well documented, with approximately one in three individuals experiencing at least one episode during their lifetime, debilitating symptoms including neuropathic pain, and complications such as post-herpetic neuralgia, vision loss, and rarely, stroke, and increased severity in immunocompromised individuals...

OBJECTIVES: The aim of this study was to investigate the shape of the time-varying relationship between herpes zoster infection, nominally shingles, and the occurrence of stroke. STUDY DESIGN: Retrospective cohort study. METHODS: Using the Italian Health Search Database, a cohort of patients aged ≥18 years who were registered between 2002 and 2021 was selected. In this cohort, a nested case-control analysis was used to model the time-varying distance (in months) between the dates of shingles and post-herpetic stroke, using a regression cubic spline, based on the odds of the occurrence of stroke compared with those without shingles...

BACKGROUND: Herpes Zoster Neuralgia (HZN) and Post-Herpetic Neuralgia (PHN) are neuropathic pain conditions following Varicella Zoster Virus infection. PHN primarily affects individuals aged 60 and above and the pervasive and severe neuropathic pain in PHN leads to significant emotional and psychological distress in approximately 80%-90% of patients, precipitating a decline in their overall quality of life and that of their families. Galectin-3, a pro-inflammatory factor, is implicated in inflammatory responses, potentially influencing neuronal damage and pain signal transmission...

Background and Objectives : The COVID-19 pandemic affects various populations worldwide. The discovery of vaccinations was necessary for the prevention and elimination of the disease. Despite the high importance of these vaccinations, they may cause some complications, such as ocular complications. This study aims to draw attention to the possible complications of the vaccination and highlight its importance. Materials and Methods : Systematic review of the literature from January 2021 to January 2023. A total of 20 published articles were included and reported cases of ocular complications in patients who received COVID-19 vaccines...

PURPOSE: To report a rare case of dematiaceous fungal keratitis caused by Cladophialophora boppii ( C. boppii ) in an immunocompromised patient. OBSERVATIONS: An 83-year-old male with chronic renal failure was referred to the Department of Ophthalmology, Kyoto Prefectural University of Medicine, Kyoto, Japan due to persistent corneal epithelial defects (PEDs) in his left eye. Initial examination revealed decreased central corneal sensitivity and decreased tear secretion in that eye, both thought to be associated with herpetic keratitis...

Chronic varicella zoster virus (VZV) infection induced neuroinflammatory condition is the critical pathology of postherpetic neuralgia (PHN). The immune escape mechanism of VZV remains to be elusive. Due to mice have no VZV infection receptor, herpes simplex virus type 1 (HSV-1) infection is a well-established PHN mice model. Transcriptional expression analysis identified that the protein arginine methyltransferases 6 (Prmt6) was upregulated upon HSV-1 infection, which was further confirmed by immunofluorescence staining in spinal dorsal horn...

Herpes simplex virus 1 (HSV-1) causes necrotizing encephalitis, usually located in the temporal lobes and with a high mortality rate if not diagnosed and treated early. Cranial computed tomography (CT) scan, although not very sensitive, can help by highlighting hemorrhagic foci and edema in the frontotemporal lobes, given the tropism of the virus for these areas. We present the case of a 70-year-old male who came to the emergency department (ED) with fever and confusion. Despite an unclear cerebrospinal fluid (CSF) result, the CT scan showed a spot of hypodensity in the mesial aspect of the left temporal lobe...

PURPOSE: The objective of this study is to report a case of unilateral acute retinal necrosis (ARN) with contralateral eye presenting as non-necrotizing herpetic uveitis. CASE REPORTS: Case 1: A 48-year-old female presented at our clinic with blurred vision in the right eye for 7 days. She was diagnosed with ARN in the left eye 2 weeks ago. Ophthalmic examination revealed reduced visual acuity in the right eye (20/33) with the presence of optic disc swelling and macular exudation without peripheral necrotic lesions...

The varicella-zoster virus reactivates to cause herpes zoster, commonly referred to as shingles. Shingles traditionally manifest as itchy vesicles in a dermatomal distribution, accompanied by related constitutional symptoms in immunocompetent patients. Usually, the rash resolves completely in seven to ten days. Herpetic neuralgia is the most typical herpes zoster consequence. Around 1% to 5% of individuals have motor impairments, with Ramsay-Hunt syndrome being the most prevalent ailment. Additional problems encompass abdominal pseudohernia, paralytic ileus/colonic pseudo-obstruction, hemidiaphragm paralysis, bladder dysfunction, localized paresis, constipation, and visceral neuropathy...

BACKGROUND: Herpes zoster (HZ) is a prevalent disease caused by the reactivation of the varicella-zoster virus (VZV) and associated with chronic morbidity, particularly with post-herpetic neuralgia (PHN). Inflammatory bowel disease (IBD) has been associated with an increased risk of HZ, mainly when immunosuppressive treatment (IMT) is used. However, studies assessing the risk of HZ in IBD are scarce. AIMS: To evaluate the incidence rate and risk factors of HZ in IBD...
