Ocular Surface Adverse Events are not Associated with Dupilumab use in Nasal Polyp Treatment.

Objectives: Ocular surface reactions (OSR) have been associated with dupilumab for atopic dermatitis (AD) treatment. However, the association of dupilumab-associated OSR (DA-OSR) for nasal polyps (CRSwNP) treatment has not been studied. We evaluated DA-OSR for CRSwNP treatment using the FDA Adverse Event Reporting System (FAERS).

A Patient With Myelin Oligodendrocyte Glycoprotein Positive Encephalitis With Ring Enhancing Lesions on Magnetic Resonance Imaging (MRI) After COVID-19 Exposure.

Myelin oligodendrocyte glycoprotein (MOG) antibody has been associated with a wide range of neurological diseases, from neuromyelitis optica spectrum disorder to acute disseminated encephalomyelitis. However, MOG positivity with isolated encephalitis has been infrequently reported. MRI findings are usually of the demyelination type.

Opioid Use After Orbital, Eyelid, or Lacrimal Surgery.

Purpose: Opioids may be indicated to mitigate pain after oculofacial surgery. The opioid crisis prompted attention to how these medications are dispensed and disposed. This study aims to characterize opioid usage and handling of patients undergoing oculofacial plastic surgery.

Comparison of Intraocular Pressure, Usage of Topical Steroids, Need for Intraocular Pressure Lowering Drops, and Incidence of Glaucoma Surgery Up to 2 Years After Penetrating Keratoplasty and Endothelial Keratoplasty.

Precis: A retrospective review of 239 eyes comparing intraocular pressure (IOP), steroid needs, IOP-lowering drop needs, and incidence of glaucoma surgery between endothelial keratoplasty and penetrating keratoplasties (PKP) at multiple timepoints postoperatively up to 2 years.

Purpose: The purpose of this study was to compare postoperative IOP, steroid use, IOP-lowering drop use, and need for glaucoma surgery between PKP, Descemet membrane endothelial keratoplasty (DMEK) and Descemet stripping automated endothelial keratoplasty (DSEK).

Materials And Methods: A retrospective chart review of all PKP, DMEK, and DSEK surgeries was performed between July 1, 2012 and July 1, 2017 at the University of California, Irvine.

Endoscopic versus external dacryocystorhinostomy: temporal and regional trends in the United States Medicare population.

: Endoscopic surgeries, such as dacryocystorhinostomy (DCR), are increasingly performed for orbital and lacrimal conditions. This study describes and compares recent trends in endoscopic DCR with open, or external, DCR in the United States (US). : Medicare-Part-B National Summary data files were analyzed from 2000 to 2015 for temporal and geographic trends in endoscopic and external DCR.

Reduced Uteroplacental Perfusion Pressure (RUPP) causes altered trophoblast differentiation and pericyte reduction in the mouse placenta labyrinth.

This study characterized the effect of the reduced utero-placental perfusion pressure (RUPP) model of placental insufficiency on placental morphology and trophoblast differentiation at mid-late gestation (E14.5). Altered trophoblast proliferation, reduced syncytiotrophoblast gene expression, increased numbers of sinusoidal trophoblast giant cells, decreased Vegfa and decreased pericyte presence in the labyrinth were observed in addition to changes in maternal blood spaces, the fetal capillary network and reduced fetal weight.

Light Perception Vision Recovery After Treatment for Calcium Hydroxylapatite Cosmetic Filler-Induced Blindness.

A 51-year-old woman presented with no light perception vision of the right eye 12 hours after another provider injected calcium hydroxylapatite into the glabella and dorsum of the nose. Exam and fluorescein angiography demonstrated optic nerve edema and choroidal hypoperfusion consistent with ischemia of the posterior ciliary circulation. The central retinal circulation appeared intact.

Reversible Venting Stitch for Fenestrating Valve-less Glaucoma Shunts.

Purpose: The purpose of this is to describe a venting stitch modification for valveless glaucoma aqueous shunts and characterize early postoperative intraocular pressure (IOP) and glaucoma medication use following the modification.

Materials And Methods: Retrospective chart review of 61 sequential patients undergoing Baerveldt glaucoma implant (BGI)-350 implantation at the Doheny Eye Institute. Twenty-four patients received a glaucoma shunt with venting stitch modification (modified BGI) and 37 patients received an unmodified shunt (BGI-only).

Sca-1 identifies a trophoblast population with multipotent potential in the mid-gestation mouse placenta.

Trophoblast stem (TS) cells in the mouse derive from the polar trophectoderm of the blastocyst and persist through early gestation (to E8.5) to support placental development. Further development and growth is proposed to rely on layer-restricted progenitor cells.

Evaluating Didactic Methods for Training Medical Students in the Use of Bedside Ultrasound for Clinical Practice at a Faculty of Medicine in Romania.

Objectives: Medical students' time is limited, so efficiency in medical education is valued. This research project aimed to determine the most effective means to teach bedside ultrasound to medical students in a 1-week training course. We hypothesized that the best method would include a combination of podcasts and hands-on teaching; therefore, there would be a statistically significant difference among the various methods of teaching.

Olanzapine-Induced Neutropenia.

Olanzapine-induced neutropenia is a rare adverse effect that is currently poorly described in literature. Although neutropenia is a known adverse effect of clozapine, it has been associated with the use of other antipsychotic medications like olanzapine. This case report describes and reviews a case of olanzapine-induced neutropenia in a schizophrenic patient.

Novel molecular and nanosensors for in vivo sensing.

In vivo sensors are an emerging field with the potential to revolutionize our understanding of basic biology and our treatment of disease. In this review, we highlight recent advances in the fields of in vivo electrochemical, optical, and magnetic resonance biosensors with a focus on recent developments that have been validated in rodent models or human subjects. In addition, we discuss major challenges in the development and translation of in vivo biosensors and present potential solutions to these problems.
