Szemészeti Klinika, Semmelweis Egyetem, Általános Orvostudományi Kar Budapest, Üllői út 26., 1085.

Since 2017, the nomenclature of Fusarium, Acremonium and Sarocladium species have changed, as these morphologically homogeneous, but phylogenetically heterogeneous species and species complexes may be differentiated using MALDI-TOF MS examination, analyzing nucleotic sequences. This resulted in taxonomical changes. We summarize the clinical course, diagnostic and therapeutic options of keratitis caused by Fusarium and Sarocladium. Read More

Childhood Lead Poisoning: A Perpetual Environmental Justice Issue?

J Public Health Manag Pract 2019 Jan/Feb;25 Suppl 1, Lead Poisoning Prevention:S115-S120

Lead Poisoning Prevention and Environmental Health Tracking Branch, Division of Environmental Health Science and Practice (Dr Whitehead) and Office of Priority Projects and Innovation (Dr Buchanan), National Center for Environmental Health, Centers for Disease Control and Prevention, Atlanta, Georgia.

As the amount of lead in the environment has significantly decreased with the removal of lead in gasoline and paint, the United States has made great strides in preventing lead poisoning or reducing levels of lead in young children's blood. Even so, lead exposure is not equal for all children-low-income and minority children continue to bear a disproportionate burden of exposure primarily through contact with deteriorating lead-based paint from older housing and potentially through drinking contaminated water resulting from failing leaded pipes, as evidenced by the recent events in Flint, Michigan. These facts suggest that childhood lead poisoning is an environmental justice issue worthy of public health consideration and action; "environmental justice" is focused on identifying and addressing disproportionately high and adverse effects of environmental hazards on low-income and minority communities.

An Amplifying Cascade of Contact Lens-Related End-of-Day Hyperaemia and Dryness Symptoms.

Curr Eye Res 2018 Jul 9;43(7):839-847. Epub 2018 Apr 9.

a School of Optometry and Vision Science , University of New South Wales , Kensington , Australia.

End-of-day (EOD) symptoms of dryness are too often the cause of poor soft contact lens (SCL) tolerance and abandonment of wear. This review examines an amplifying cascade model for these symptoms, which involve thin tear layers on contact lens (CL) front surfaces being susceptible to evaporation-related short tear breakup (TBU) times. Susceptibility to faster tear loss by evaporation may be exacerbated by other forms of tear instability, such as lipid and mucin deficiencies as well as lens surface soiling. Read More

Formation, growth and applications of femtoliter droplets on a microlens.

Phys Chem Chem Phys 2018 Feb;20(6):4226-4237

School of Electrical and Power Engineering, China University of Mining and Technology, Xuzhou, Jiangsu Province 221000, China.

Formation and growth of femtoliter droplets on surface microstructures are important in many fundamental and practical interfacial processes, such as water collection, vapour condensation in cooling devices, drop self-removal on anti-icing surfaces and fabrication of droplet-templated functional microstructures. In this work, we experimentally and theoretically investigate the growth of femtoliter oil-like liquid on the microlens surrounded by a hydrophilic planar area. The droplets were produced by solvent exchange, a process where the droplets nucleate and grow from an oversaturation created by displacing a good solvent by a poor solvent of the droplet liquid.

a Paediatric Ophthalmology and Strabismus , Moorfields Eye Hospital , London , UK.

Purpose: The optimal management of infantile nystagmus syndrome (INS) is still unclear. Contact lenses (CL) may be superior to glasses in improving visual function in INS but it is not known whether their beneficial effects are due to optical correction alone, or to an additional proprioceptive effect, and whether soft CLs would be as effective as rigid CLs. There is little data on feasibility and and the present study aimed to provide this information. Read More

Open Ophthalmol J 2017 31;11:241-251. Epub 2017 Jul 31.

Institute of Ophthalmology and Ocular Microsurgery 'Ophthalmica', Thessaloniki, Greece.

Background: Keratoconus is a chronic, bilateral, usuallly asymmetrical, non-inflammatory, ectatic disorder, being characterized by progressive steepening, thinning and apical scarring of the cornea. Initially, the patient is asymptomatic, but the visual acuity gradually decreases, resulting in significant vision loss due to the development of irregular astigmatism, myopia, corneal thinning and scarring. The classic treatment of visual rehabilitation in keratoconus is based on spectacles and contact lenses (CLs). Read More
