Plexiform Schwannoma of the Eyelid.

Plexiform schwannoma of the lacrimal gland of the palpebral lobe has not been previously described. This 41-year-old male presented with a 2-year history of a left upper eyelid mass and associated regional irritation. MRI of the head and orbits confirmed a left superolateral multinodular mass centered on the palpebral lobe of the left lacrimal gland. Excision revealed a schwannoma of the plexiform subtype.

Sinonasal Chondrosarcoma With Unusual Orbital Invasion.

A case is presented of a 43-year-old male with a chronic history of progressive nasal obstruction and epiphora. MRI confirmed a heterogeneous mass involving the middle and superior turbinates with T2 hyperintense and calcified components, with extension into the inferomedial orbit. Tissue biopsy revealed a grade 2 chondrosarcoma of the conventional subtype. Endonasal wide local resection of the lesion was performed with clear margins. The patient had no functional sequelae and will undergo routine surveillance.

Imaging Features of Invasive Fungal Rhinosinusitis: A Systematic Review.

Fungal rhinosinusitis (FRS) includes non-invasive and invasive subtypes with the latter having significant morbidity and mortality. This systematic review aims to identify the imaging features most correlated with invasive fungal rhinosinusitis (IFRS) and present a checklist of these features to aid diagnosis. PubMed, Embase, CENTRAL, and Science Direct were searched from inception to May 2023, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Primary research articles published in English describing the imaging features of IFRS were included. The systematic review was conducted in accordance with the PRISMA guidelines. Forty-eight articles were identified for inclusion. Six studies examined radiological features in acute invasive fungal rhinosinusitis (AIFRS), and 9 studies of chronic invasive fungal rhinosinusitis (CIFRS). A majority of studies did not specify whether IFRS cases were acute or chronic. On CT, bony erosion and mucosal thickening were the most common features. Other features include nasal soft tissue thickening, nasal cavity opacification, opacification of the affected sinus, and perisinus soft tissue infiltration. Extra-sinus extension was commonly observed on MRI, most often invading intraorbitally and intracranially. Other sites of extra-sinus extension included the cavernous sinus, pterygopalatine fossa, infratemporal fossa, masticator space, and facial soft tissue. IFRS is a condition with potential for high morbidity and mortality. Several radiological features are highly suggestive of IFRS. Early identification of high-risk radiological features using a checklist may aid prompt diagnosis and early treatment. Future research investigating the radiological differentiation between IFRS and other significant pathology including bacterial orbital cellulitis would be beneficial.

One-Year Outcomes of Preserflo Microshunt for Primary Open Angle Glaucoma: A Systematic Review and Meta-Analysis.

PRCIS: This systematic review and meta-analysis concludes that the PreserFlo Microshunt glaucoma drainage device significantly reduces intraocular pressure in primary open angle glaucoma patients at 12 months postinsertion. PURPOSE: A systematic review and meta-analysis on the effect of the PRESERFLO MicroShunt (PF-MS) on intraocular pressure (IOP) at 12 months has been conducted. METHOD: The PubMed/MEDLINE, Embase, CENTRAL, Google Scholar, Scopus, and Web of Science databases were searched. Inclusion criteria required a diagnosis of open angle glaucoma, PF-MS insertion, and examination of IOP over time. Meta-analyses were conducted on the primary outcome of IOP and the secondary outcome of glaucoma medication regime. Adverse events were also noted. RESULTS: Fourteen studies were identified for inclusion in the meta-analyses, of which none had a high risk of bias. The meta-analyses found a significant mean reduction in IOP of 9.07 mm Hg (95% CI: 7.88-10.25; P <0.0001) and a significant mean reduction in mean glaucoma medication requirement of 2.37 medications (95% CI: 2.15-2.60; P <0.0001). Hypotony and hyphaema are common early complications. CONCLUSIONS: The PF-MS device significantly reduced both IOP and glaucoma medication requirement at 12 months postinsertion in individuals with open angle glaucoma without a significant adverse event burden. Further research is required to determine the economic and environmental effects of widely implementing the PF-MS device into clinical practice.

Primary Dacryocystorhinostomy for Acute Dacryocystitis: A Systematic Review.

INTRODUCTION: Acute dacryocystitis is a common condition occurring secondary to nasolacrimal duct obstruction. We aim to assess the efficacy of primary dacryocystorhinostomy for the management of acute dacryocystitis. METHODS: A systematic search of the databases PubMed/MEDLINE, Embase, and CENTRAL was performed to December 2023. Data extraction and risk of bias analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS: Fourteen articles fulfilled inclusion criteria. The results demonstrated that for the treatment of acute dacryocystitis, primary dacryocystorhinostomy (DCR) is anatomically and functionally efficacious, with low complication rates and minimal risk of recurrence. The anatomical success rates for primary endonasal DCR (EnDCR) were 81.8-100%, 83.8-87.5% in delayed EnDCR and 66-100% in delayed external DCR (ExDCR). Functional success was generally defined as a subjective absence of epiphora, which was achieved in 86.4-92.0% of primary EnDCR, and 0-89.5% of the delayed ExDCR cohorts. Two randomized controlled trials established equivalent rates of functional success between primary versus delayed EnDCR (87.5% vs 87.5% and 91.3% vs 92.3%). Increased perioperative bleeding was recorded in 27.8% of primary EnDCR cases in 1 study. ExDCR was infrequently associated with postoperative fistula and scar formation and cicatricial punctal ectropion. The mean length of admission trended to be shorter when the procedure was performed closer to the acute presentation. The admission time for all primary EnDCR cases varied between 1 and 7 days. CONCLUSION: Primary dacryocystorhinostomy is an efficacious and safe management option for acute dacryocystitis. Further analyses of health-economics are required.

Current management options for the treatment of refractory postoperative cystoid macular edema: A systematic review.

Post-operative cystoid macular edema (PCME) is an important complication following intraocular surgery that often resolves spontaneously without treatment. In some cases, PCME may persist despite initial medical therapy, which can adversely impact visual outcomes. Various topical, intraocular and systemic treatments exist for the prevention and management of cystoid macular edema; however, there is no consensus on treatment of refractory cases in the postoperative setting. In accordance with the PRISMA guidelines, we systematically reviewed 68 articles describing management options and their outcomes for treatment-resistant cases of PCME. The most commonly reported treatments included steroid (39 studies) and biological-based (17 studies) therapies. We provide an overview of the treatment options for refractory PCME.

Near-death experiences after cardiac arrest: a scoping review.

BACKGROUND: This scoping review aimed to characterise near-death experiences in the setting of cardiac arrest, a phenomenon that is poorly understood and may have clinical consequences. METHOD: PubMed/MEDLINE was searched to 23 July 2023 for prospective studies describing near-death experiences in cardiac arrest. PRISMA-ScR guidelines were adhered to. Qualitative and quantitative data were synthesised. Meta-analysis was precluded due to data heterogeneity. RESULTS: 60 records were identified, of which 11 studies involving interviews were included from various countries. Sample size ranged from 28-344, and proportion of female patients (when reported) was 0-50%, with mean age (when reported) ranging 54-64 years. Comorbidities and reasons for cardiac arrest were heterogeneously reported. Incidence of near-death experiences in the included studies varied from 6.3% to 39.3%; with variation between in-hospital (6.3-39.3%) versus out-of-hospital (18.9-21.2%) cardiac arrest. Individual variables regarding patient characteristics demonstrated statistically significant association with propensity for near-death experiences. Reported content of near-death experiences tended to reflect the language of the questionnaires used, rather than the true language used by individual study participants. Three studies conducted follow-up, and all suggested a positive life attitude change, however one found significantly higher 30-day all-cause mortality in patients with near-death experiences versus those without, in non-controlled analysis. CONCLUSIONS: From prospective studies that have investigated the phenomenon, near-death experiences may occur in as frequent as over one-third of patients with cardiac arrest. Lasting effects may follow these events, however these could also be confounded by clinical characteristics.
