In this work, we examine the strength of deep learning approaches for pathology detection in chest radiographs. Convolutional neural networks (CNN) deep architecture classification approaches have gained popularity due to their ability to learn mid and high level image representations. We explore the ability of CNN learned from a non-medical dataset to(More)
We report a case of hemimegalencephaly diagnosed by prenatal MRI with an emphasis on its appearance on diffusion-weighted images. This case shows that in this condition the enlarged hemisphere may show restricted diffusion on prenatal MRI. In our opinion, this finding may result from a combination of increased cellularity and advanced myelination in the(More)
A gradual increase in blood pressure (BP), often attaining hypertensive levels, is common during aging--"age-related hypertension." Therefore, means to prevent or ameliorate this elevated BP safely are important. Although oral B-nicotinamide adenine dinucleotide (NADH), a natural coenzyme, is used principally to treat various neurologic disorders, we wished(More)
BACKGROUND An outbreak of respiratory illness caused by a novel swine-origin influenza virus (influenza A/H1N1 2009) that began in Mexico was declared a global pandemic by the World Health Organization in June 2009. The pandemic affected many countries, including Israel. OBJECTIVES To compare the course of chest radiographic and computed tomography(More)
We hypothesize that children with fusional and/or accommodative abnormalities will tend to tire more readily when reading than will children with normal vision and that, consequently, they will show a greater decrement in reading proficiency over time on a task requiring reading. Forty-five subjects who passed the New York State Optometric Association(More)
Daily turnover of cholesterol obtained by the balance method was compared to daily input rates calculated by input-output analysis in 43 experiments. The mean value of input rates for kinetic data of 10.1-16.4 weeks' duration (14 experiments) was 1.05 g/day vs. the chemical turnover of 0.94 g/day (difference 10.9 percent). For decay curves of 4.8-9.9 weeks'(More)

Data on the prevalence of visual disorders in special populations as well as in normal populations is sparse. Fifty-five students in a special education school were given a comprehensive screening for pathology, acuity, refractive error, fusion, oculomotor, and perceptual motor skills. This group had a very high prevalence of visual disorders especially(More)
BACKGROUND In a recent multicenter study, percent free prostate-specific antigen (PSA) enhanced the specificity of PSA testing in prostate cancer screening. OBJECTIVE To determine whether the percent free PSA could be as effective in reducing the need for biopsy in a managed care setting as in an academic setting. SETTING Kaiser Permanente Northwest(More)
