PURPOSE To test the hypothesis that the presence of bacteria and/or histologic inflammation in the placenta of infants born preterm is associated with an increased risk for severe retinopathy of prematurity (ROP). METHODS This was a prospective cohort study. Exploratory and multivariable data analyses were used, including logistic regression models with interaction terms. Main outcomes were f...

BACKGROUND Limited data are available to describe the spectrum of severity of neonatal chronic lung disease. In the multicenter Supplemental Therapeutic Oxygen for Prethreshold Retinopathy of Prematurity trial, all infants had some degree of pulmonary dysfunction, because eligibility required a median oxygen saturation of < or =94% with room air. Infants randomized to the supplemental oxygen gr...

Many environmental stimuli contain temporal regularities, a feature that can help predict forthcoming input. Phase locking (entrainment) of ongoing low-frequency neuronal oscillations to rhythmic stimuli is proposed as a potential mechanism for enhancing neuronal responses and perceptual sensitivity, by aligning high-excitability phases to events within a stimulus stream. Previous experiments s...

OBJECTIVES To evaluate one-year structural outcomes of bedside diode laser photocoagulation with remifentanil analgesia for retinopathy of prematurity (ROP) and discuss clinical and demographic characteristics of infants and other possible risk factors that may affect the outcome. MATERIALS AND METHODS The medical records of premature infants who were treated with bedside transpupillary diode...

AIM To determine if a non-ophthalmologist can accurately screen for retinopathy of prematurity (ROP) by evaluating the posterior pole blood vessels of the retina. ROP is a common ocular disorder of premature infants and may require multiple screening examinations by an ophthalmologist to allow for timely intervention. Since there is a strong correlation between posterior pole vascular abnormali...

It has been well established that laser treatment for type 1 prethreshold retinopathy of prematurity is effective in approximately 90 percent of treated eyes, avoiding retinal detachment.1 Transpupillary laser therapy is certainly the standard; however, there are circumstances in which transpupillary treatment may be difficult or impossible to perform thus allowing progression of retinopathy of...

BACKGROUND The Early Treatment for Retinopathy of Prematurity study (ETROP), published in 2003, established new guidelines for treatment of retinopathy of prematurity (ROP) and demonstrated improved outcomes compared to previous guidelines. We examined outcomes before and after implementing the ETROP recommendations. METHODS A retrospective chart review was performed using records of infants ...

PURPOSE To determine whether a multivariate risk model can select infants with low-risk eyes for an alternative protocol that reduces retinopathy of prematurity (ROP) screening without loss of effectiveness. METHODS This was a retrospective, nonrandomized, comparative study. We assigned 712 eyes of 357 premature infants of 401-1,250 g birth weights as high or low risk for prethreshold or thre...

To cite: Bello Z. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014206826 DESCRIPTION A female baby was born at 24 weeks gestation, weighing less than 600 g. Owing to the extremely low birth weight and gestation age, she was at risk of developing sight threatening retinopathy of prematurity (ROP) 2 and therefore eligible for screening, which subsequently demons...

We show that differences in parameter values of the Anderson model obtained from an analysis of the Ce 3d core level spectra between CeRhs and CeO2 well explain a remarkable difference in the Ce 4d core photoabsorption spectrum between the two by introducing interactions given by the Slater integrals and spin-orbit ones. The purpose of this work is t o present an interpretation for the Ce 4d-co...
