Balloon-mounted versus self-expandable stent in failed neurothrombectomy: a post hoc analysis of the SAINT study.

Background: Previous studies have shown that when thrombectomy has failed, rescue intracranial stenting is associated with better clinical outcomes compared with failed reperfusion. However, comparative data regarding stent type are lacking.

Objective: To compare the procedural and clinical outcomes of balloon-mounted stents (BMS) with those of self-expandable stents (SES).

Polydipsia Induced Acute Angle-Closure Crisis.

We present a case of Acute Angle-Closure Crisis (AACC) precipitated by primary transient psychogenic polydipsia; we believe that our case is the first of its kind to be reported. A 74-year-old male presented to the emergency department with altered mental status due to acute-onset hyponatremia. Six days after admission, the patient noticed painful loss of vision in his right eye and an ipsilateral headache lasting 10-15 minutes.

The hypercapnic environment on the International Space Station (ISS): A potential contributing factor to ocular surface symptoms in astronauts.

With increasing advancements and efforts towards space exploration, there is a pressing need to understand the impacts of spaceflight on astronauts' health. Astronauts have reported signs and symptoms of dry eye disease upon traveling to the International Space Station (ISS), thus necessitating an evaluation of the factors that contribute to the onset of spaceflight associated dry eye disease. Prior literature describes the hypercapnic environment of the ISS; however, the link between the high CO levels and astronauts' symptoms of dry eye disease remains unexplored.

A multifactorial, evidence-based analysis of pathophysiology in Spaceflight Associated Neuro-Ocular Syndrome (SANS).

The National Aeronautics and Space Administration (NASA) in the United States has been studying a fascinating and unique constellation of neuro-ophthalmic findings collectively known as Spaceflight Associated Neuro-Ocular Syndrome (SANS). SANS is unique to the space environment of microgravity and produces novel physiological and pathological findings that have no direct terrestrial equivalent. The neuro-ophthalmic phenomenon is a major physiologic barrier to future planetary spaceflight.

Necrosis of pleomorphic adenoma of the lacrimal gland with acute and chronic arteriolar occlusion.

Pleomorphic adenoma of the lacrimal gland (PALG) is a benign neoplasm typically presenting with gradual, painless globe displacement and/or lid swelling. We report an atypical case of PALG in a 53-year old male presenting acutely, mimicking orbital cellulitis. Imaging demonstrated an extraconal rim-enhancing soft-tissue lesion medial to the left lacrimal gland, involving superior rectus and levator palpebrae superioris.

Assessing the Risk of Kidney Stone Development in Patients With Idiopathic Intracranial Hypertension Treated With Carbonic Anhydrase Inhibitors.

Background: The prevalence of idiopathic intracranial hypertension (IIH) is rising with the global obesity epidemic. Carbonic anhydrase inhibitors (CAIs), such as acetazolamide, have been shown to be effective in IIH but can also lead to kidney stone formation. This study evaluates the risk of kidney stone development in patients with IIH treated with CAIs.

Herpes zoster ophthalmicus temporally after COVID-19 vaccination: a systematic review of uncontrolled case reports and case series.

Purpose: Herpes zoster ophthalmicus (HZO) following COVID-19 vaccination has been reported previously but the clinical characteristics, onset, treatment, and outcomes of these cases have not been previously systematically reviewed.

Methods: A systematic review, guided by PRISMA guidelines, surveyed PubMed and Embase databases from April 2021 to June 2023 for case reports and series detailing HZO following COVID-19 vaccination. Studies excluded were abstracts, reviews, and clinical trials.

Influence of Common Medications on Diabetic Macular Edema in Type 2 Diabetes Mellitus.

Purpose: This study aimed to assess the impact of systemic medications, including glucagon-like peptide-1 receptor agonists (GLP-1 RAs), fenofibrates, thiazolidinediones (TZDs), and calcium channel blockers (CCBs), on the risk of developing diabetic macular edema (DME) in patients with type 2 diabetes mellitus (T2DM).

Design: A retrospective cohort study was conducted using electronic medical records (EMR) data from the TriNetX health research network, covering a period from October 2004 to 2024.

Participants: The study population comprised patients diagnosed with T2DM who were newly initiated on GLP-1 RAs, fenofibrates, TZDs, or CCBs.

The potential role of retinal slip in National Football League (NFL) officiating and its effect on on-field decision making: mechanisms and countermeasures.

Visual processing involves numerous neuro-ophthalmic pathways that enable humans to perceive and interact with the world. These visual pathways can negatively impact visual perception and decision-making. The Vestibulo-Ocular Reflex (VOR) is a compensatory mechanism that stabilizes gaze on a target during head movement, such as running or turning.

The optic nerve in spaceflight: novel concepts in the pathogenesis of optic disc edema in microgravity.

Purpose Of Review: Spaceflight-associated neuro-ocular syndrome (SANS) encompasses a unique constellation of neuro-ocular findings in astronauts, including optic disc edema (ODE), globe flattening, chorioretinal folds, and hyperopic refractive shift. Although there are numerous neuro-ocular findings in SANS, the purpose of this review is to describe the novel, emerging concepts of the pathogenesis for the ODE specifically in SANS.

Recent Findings: While the initial hypotheses on the pathogenesis of ODE in SANS focused on possible elevated intracranial pressures (i.

Dural arteriovenous fistula (DAVF) after venous sinus stent (VSS) for presumed idiopathic intracranial hypertension (IIH): A case report and literature review.

Dural arteriovenous fistulas (DAVFs) are rare but significant intracranial vascular malformations that are usually idiopathic and can lead to severe complications like venous hypertension and intracranial hemorrhage. We present 2 cases of DAVF occurring after venous sinus stenting (VSS) for presumed idiopathic intracranial hypertension (IIH) in a 51-year-old and a 52-year-old female. In both patients, Cognard type 1 DAVF was detected by Catheter angiography and successfully obliterated with Onyx™ embolization.

Esophagitis in a Post-Liver Transplant Patient: A Case of Cytomegalovirus and Herpes Simplex Virus-1 Coinfection.

In post-liver transplant patients, esophagitis presents a diagnostic and management challenge due to the potential for opportunistic infections. This case describes a 59-year-old female with primary sclerosing cholangitis who underwent orthotopic liver transplantation six years prior. She presented with dysphagia, and her medical history included immunosuppression with prednisone, tacrolimus, and mycophenolate and a history of achalasia treated with esophageal peroral endoscopic myotomy.

Could DTI Unlock the Mystery of Subjective Tinnitus: It's Time for Parameters That Go A Little Out of the Routine.

In this study, it was aimed to assess the microstructural changes in the main central auditory pathway in cases with subjective tinnitus. In total, 101 subjects (52 cases with bilateral subjective non-pulsatile tinnitus and 49 healthy cases as the control group) were included in the study.
