As atherosclerosis starts in early childhood, the process of risk evaluation must start quite early. The present review addresses the issue of cutaneous markers associated with atherosclerosis, and the strengths and weaknesses of the markers in identifying early coronary atherosclerosis. A diligent search for such clinical markers, namely xanthelasma, xanthoma, arcus juvenilis, acanthosis nigricans, skin tags, ear lobe crease, nicotine stains, premature graying in smokers, hyperpigmented hands in betel quid sellers, central obesity, and signs of peripheral vascular disease may prove to be a rewarding exercise in identifying asymptomatic CAD in high risk individuals.展开更多

Methods: A total of 137 children born after ICSI and 159 control children were examined at the age of 5 years in a blinded study. The two groups were matched for age, gender and maternal age. The children underwent a detailed ophthalmological investigation by an ophthalmologist and an orthoptist. Results: A total of 90.4% of the ICSI children had a visual acuity (VA) in the better eye of ≥ 0.8, compared with 93.7% of the controls (NS). No significant differences were found between ICSI children and controls with regard to hyperopia, myopia, astigmatism, heterotropia, stereoscopic vision and convergence. One child with Goldenhar syndrome and one with Marcus Gunn syndrome were observed in the ICSI group. One child in the ICSI group was treated for retinopathy of prematurity. Conclusion: In this limited study group, no significant differences in visual function and/or ocular morphology were found between children born after ICSI and matched control children at the age of 5 years.展开更多
