Fast versus gradual adaptation of soft daily disposable contact lenses in neophyte wearers.

Cont Lens Anterior Eye 2020 Jun 20;43(3):268-273. Epub 2019 Sep 20.

Faculty of Biology, Medicine and Health, The University of Manchester, Manchester, UK. Electronic address:

Purpose: Despite the widespread practice of gradually adapting all new soft contact lens wearers (neophytes), there is little evidence-based research underpinning such practice. This work determined if a gradual adaptation period is necessary for neophytes when fitted with modern hydrogel or silicone-hydrogel daily disposable contact lenses.

Method: At four sites, neophytes (19-32 years) were randomly assigned to an adaptation schedule: fast (10 h wear from the first day) or gradual (4 h on the first day, increasing their wear-time by 2 h on each subsequent day until they had reached 10 h) with hydrogel (n = 24 fast; n = 21 gradual) or silicone-hydrogel (n = 10 fast; n = 10 gradual) contact lenses.

Corneal ectasia following cataract extraction surgery in a patient with keratoconus: a case report.

J Med Case Rep 2019 Sep 19;13(1):296. Epub 2019 Sep 19.

Department of Ophthalmology, University Hospital of Alexandroupolis, Dragana, 68100, Alexandroupolis, Greece.

Background: According to experimental and clinical published studies, patients with keratoconus have a genetic predisposition to corneal ectasia; however, ectasia might not be activated or reactivated unless an additional stressful event triggers the disease. Triggering factors are sources of reactive oxidative stress; among them, mechanical trauma (vigorous eye rubbing, poorly fit contact lenses), exposure to ultraviolet light, and atopy/allergies. The aim of this case report is to present for the first time a case of rapidly progressive corneal ectasia in a patient with keratoconus following uncomplicated phacoemulsification surgery for cataract removal.

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.
