Automated Capsular Decompression to Avoid Argentinian Flag Sign in Intumescent Cataract.
Clin Ophthalmol
July 2024
Department of Ophthalmology and Visual Sciences, Federal University of São Paulo (UNIFESP), São Paulo, São Paulo, Brazil.
Article Synopsis
- The study presents a new automated technique for cataract surgery to prevent the "Argentinian Flag sign," which can occur during capsulorhexis in intumescent cataracts, by using an insulin needle for simultaneous puncture and decompression of the capsular bag.
- Conducted at two medical facilities in São Paulo, Brazil, the prospective interventional study involved 88 patients with white or intumescent cataracts, utilizing standard surgical procedures and equipment.
- Results showed no complications, with a perfect 100% success rate for achieving a continuous and well-centered capsulorhexis in all cases.
Maximizing Performance and Stability of Organic Solar Cells at Low Driving Force for Charge Separation.

Thanks to the development of novel electron acceptor materials, the power conversion efficiencies (PCE) of organic photovoltaic (OPV) devices are now approaching 20%. Further improvement of PCE is complicated by the need for a driving force to split strongly bound excitons into free charges, causing voltage losses. This review discusses recent approaches to finding efficient OPV systems with minimal driving force, combining near unity quantum efficiency (maximum short circuit currents) with optimal energy efficiency (maximum open circuit voltages).

JAMA Ophthalmol
November 2023
Retinal Diagnostic Center, Campbell, California.
Importance: Recently, intravitreal pegcetacoplan became the first drug to gain US Food and Drug Administration approval for the treatment of geographic atrophy associated with nonexudative age-related macular degeneration, but the administration of this medication may be associated with unanticipated posttreatment complications.
Objective: To assess the prevalence of presumed silicone oil droplets in the vitreous cavity after intravitreal injection of pegcetacoplan.
Design, Setting, And Participants: This case series study involved a retrospective record review of all 55 patients treated with intravitreal pegcetacoplan, 0.
Surgical airway approaches are, at times, last resort options in difficult airway management. In Special Operations these interventions confront distorted anatomy from combat trauma, extreme conditions, and may be performed by non-medically trained personnel. Under these circumstances, needle cricothyroidotomy using a large bore intravenous catheter can be considered.

J Foot Ankle Surg
March 2022
Resident, Foot & Ankle Surgery, Regions Hospital/HealthPartners Institute for Education and Research, Saint Paul, MN.
Article Synopsis
- There are no clear treatment guidelines for amputations due to forefoot gangrene, leading to high rates of poor outcomes related to infection.
- A study involving 100 patients undergoing various types of forefoot amputation revealed that a significant majority had underlying osteomyelitis, with a worse prognosis for those infected at the time of surgery.
- Earlier amputations for stable gangrene may reduce the risk of acute infections and osteomyelitis, potentially improving post-surgical outcomes, indicating a need for further research in this area.
