[Lens injury as a complication of intravitreal medication injection].

Background: Intravitreal medication injections are an efficient and low-risk delivery technique for treating various retinal diseases. Rare serious complications include increased intraocular pressure, vitreous hemorrhage, retinal tears and detachment, intraocular inflammation and endophthalmitis. In the case series presented here, we report iatrogenic lens injuries caused by inadequate performance of intravitreal injections.

[Iatrogenic retinal defects after intravitreal operative drug injections].

Background: Intravitreal operative drug injections represent one of the most frequently performed medical interventions. The risk profile is low. In addition to intraocular pressure elevation, the most frequent complications include exogenous endophthalmitis, vitreous hemorrhage and rhegmatogenous retinal detachment.

Long-Term Outcome and Complications of IOL-Exchange.

Purpose: To describe the long-term outcome after intraocular lens (IOL) exchange for IOL-opacification with a focus on any occurring complications.

Patients And Methods: Patients with an IOL exchange for opacified IOLs (Lentis LS-502-1) were identified. Medical records and information from the treating ophthalmologists were reviewed.

Jewish Community Studies in the Twenty-First Century.

Periodic measurement of the size and behaviors of the Jewish population is of vital importance to Jewish communal planners, both nationally and in communities throughout the United States. Methodological design decisions, such as the choice of a sampling frame, mode of data collection, nonresponse follow-up protocols, and definition of eligibility can have significant impacts on population estimates. This paper demonstrates how two studies, one national and one for the Jewish Federation of Greater Philadelphia used the current state-of-the-art address-based sampling methodology and other methodological improvements to significantly increase coverage and reduce bias in the survey results compared to other methodologies.

Serial opacification of a hydrophilic-hydrophobic acrylic intraocular lens: analysis of potential risk factors.

Purpose: To identify potential risk factors related to the opacification of a hydrophilic-hydrophobic acrylic intraocular lens (IOL) model.

Setting: University Hospital Regensburg, Department of Ophthalmology, Regensburg, Germany.

Design: Cross-sectional study.

State-level estimation of diabetes and prediabetes prevalence: Combining national and local survey data and clinical data.

Many statisticians and policy researchers are interested in using data generated through the normal delivery of health care services, rather than carefully designed and implemented population-representative surveys, to estimate disease prevalence. These larger databases allow for the estimation of smaller geographies, for example, states, at potentially lower expense. However, these health care records frequently do not cover all of the population of interest and may not collect some covariates that are important for accurate estimation.

Spectral Domain Optical Coherence Tomography Allows the Unification of Clinical Decision Making for the Evaluation of Choroidal Neovascularization Activity.

Purpose: This prospective observational clinical study investigated the benefits of spectral domain optical coherence tomography for specialists and residents in the management of neovascular age-related macular degeneration (AMD).

Procedures: The study involved 49 eyes of 44 patients. Patients were advised to present for reevaluation 4 weeks after the administration of the loading dose of vascular endothelial growth factor (VEGF)-inhibitors (3 intravitreal injections every 4 weeks after diagnosis).

Macular hole surgery: an analysis of risk factors for the anatomical and functional outcomes with a special emphasis on the experience of the surgeon.

Purpose: The aim of this study was to evaluate risk factors for the anatomical and functional outcomes of macular hole (MH) surgery with special emphasis on the experience of the surgeon.

Methods: A total of 225 surgeries on idiopathic MHs (IMHs) performed by 6 surgeons with a mean follow-up period of 20.5 months were reviewed in this retrospective study.

Atraumatic osteonecrosis of the distal radius and ulna: case series and review.

Purpose: Atraumatic multifocal osteonecrosis is defined as the occurrence of atraumatic osteonecrosis in 3 or more anatomic locations, and it is rare. We identified 6 patients with osteonecrotic lesions in the distal ulna, radius, or both. The purposes of this study were to describe the clinical manifestations of atraumatic multifocal osteonecrosis affecting these bones, to identify risk factors for developing the disease in these locations, and to evaluate the success of treatment by percutaneous drilling.

Comparison of wipe materials and wetting agents for pesticide residue collection from hard surfaces.

Different wipe materials and wetting agents have been used to collect pesticide residues from surfaces, but little is known about their comparability. To inform the selection of a wipe for the National Children's Study, the analytical feasibility, collection efficiency, and precision of Twillwipes wetted with isopropanol (TI), Ghost Wipes (GW), and Twillwipes wetted with water (TW), were evaluated. Wipe samples were collected from stainless steel surfaces spiked with high and low concentrations of 27 insecticides, including organochlorines, organophosphates, and pyrethroids.

Informed consent: interpretations and practice on social surveys.

This paper discusses interpretations and practical requirements for fulfilling informed consent on social surveys, particularly in the health field, in order to achieve a balance between two competing principles: the public good of carrying out high-quality survey research which requires unbiased representative participation; and respect for individuals' rights to refuse to participate. It examines the appropriateness of different practical procedures aimed at getting agreement to voluntary participation consistent with the requirements of informed consent. It seeks to raise awareness of the principles and practicalities of carrying out social surveys in the health field, which can inform judgements of what is appropriate ethical practice, which in turn can inform judgements of ethical review committees.

The prevalence of lead-based paint hazards in U.S. housing.

In this study we estimated the number of housing units in the United States with lead-based paint and lead-based paint hazards. We included measurements of lead in intact and deteriorated paint, interior dust, and bare soil. A nationally representative, random sample of 831 housing units was evaluated in a survey between 1998 and 2000; the units and their occupants did not differ significantly from nationwide characteristics.

First National Survey of Lead and Allergens in Housing: survey design and methods for the allergen and endotoxin components.

From July 1998 to August 1999, the U.S. Department of Housing and Urban Development and the National Institute of Environmental Health Sciences conducted the first National Survey of Lead and Allergens in Housing.
