Trachoma And Its Complications In Egypt

Scientific Foundations of Ophthalmology focuses on scientific grounds of ophthalmology, including anatomy, genetics, pathology, and epidemiology of blindness and blinding diseases. The selection first offers information on aqueous outflow pathway in vertebrate eyes; retinal receptors and pigment epithelium; and vascular supply of the optic disc. Discussions focus on glaucomatous cupping of the optic disc, venous drainage, receptor synapses, outer plexiform layer, primates, and lower mammals. The book then ponders on anatomical and neurophysiological review of cerebral control of ocular movements and the structure and transparency of the cornea. The publication elaborates on the biochemistry of lens, regulation of retinal blood flow, and biochemical basis of toxic amblyopias. The text also takes a look at the hereditary aspects of glaucoma, inborn errors of metabolism, retinal dystrophies, and gyrate atrophy of the choroid and retina with hyperornithinaemia. Vitreoretinal degenerations in myopia, retinitis pigmentosa, albinism, lens dislocation, and storage disorders involving complex lipids and carbohydrates are discussed. The selection is highly recommended for ophthalmologists and readers interested in ophthalmology.

This book explains why Islamist parties have dominated the politics of Egypt for the better part of fifty years. Analyzing Islamist electoral performance and behavior before and after the 2011 revolution that unseated former dictator Hosni Mubarak, this book argues that Islamists win elections not because Egyptians are fundamentalists, but because these parties have more organizational resources to call on than their secular rivals.

The struggle against deadly microbes is endless. Diseases that have plagued human beings since ancient times still exist, new maladies make their way into the headlines, we are faced with vaccine shortages, and the threat of germ warfare has reemerged as a worldwide threat. In this riveting account, medical historian Howard Markel takes an eye-opening look at the fragility of the American public health system. He tells the distinctive stories of six epidemics–tuberculosis, bubonic plague, trachoma, typhus, cholera, and AIDS–to show how our chief defense against diseases from outside the United States has been to attempt to deny entry to carriers. He explains why this approach never worked, and makes clear that it is useless in today’s world of bustling international travel and porous borders. Illuminating our foolhardy attempts at isolation and showing that globalization renders us all potential inhabitants of the so-called Hot Zone, Markel makes a compelling case for a globally funded public health program that could stop the spread of epidemics and safeguard the health of everyone on the planet.
