William H. Lewis has been associated with North African affairs since 1952. He conducted his doctoral research in the area under Ford Foundation sponsorship and has since held appointments in the Department of State and in the academic communityUniversity of Michigan, Georgetown University, and Johns Hopkins. Dr. Lewis has coauthored a number of books on Middle Eastern and African affairs and i...
We prospectively studied 478 patients with megaloblastic anemia living in Tunisia. Overall, 98% of patients had vitamin B12 deficiency. Pernicious anemia accounted for most of these cases, and median age at presentation was 45 years. Megaloblastic anemia occurred in 19 subjects under 15 years of age, and of these, nine had the Immerslund-Graesbeck syndrome.
UNLABELLED Of the three foot-and-mouth-disease virus SAT serotypes mainly confined to sub-Saharan Africa, SAT 2 is the strain most often recorded in domestic animals and has caused outbreaks in North Africa and the Middle East six times in the last 25 years, with three apparently separate events occurring in 2012. This study updates the picture of SAT 2 phylogenetics by using all available sequ...
We present the first speleothem-derived central North Africa rainfall record for the last glacial period. The record reveals three main wet periods at 65-61 ka, 52.5-50.5 ka and 37.5-33 ka that lead obliquity maxima and precession minima. We find additional minor wet episodes that are synchronous with Greenland interstadials. Our results demonstrate that sub-tropical hydrology is forced by both...
A fully coupled meteorology-chemistry-aerosol model (WRF-Chem) is applied to simulate mineral dust and its shortwave (SW) radiative forcing over North Africa. Two dust emission schemes (GOCART and DUSTRAN) and two aerosol models (MADE/SORGAM and MOSAIC) are adopted in simulations to investigate the modeling sensitivities to dust emissions and aerosol size treatments. The modeled size distributi...
Hydatid cyst is a parasitic disease that is endemic in Mediterranean areas, South America, North Africa, Australia, and Iran. Although the liver and lung are the most common involved organs, but the other organs in human body also can be involved by hydatid cyst. Chest wall involvement by hydatid cyst is a rare condition, which may be misdiagnosed as chest wall tumor in the endemic areas. Herei...
