1Land desertification and restoration in Middle East and North Africa(MENA) region显示文摘The Middle East and North Africa(MENA) region is characterized by high population growth, degraded and fragile natural ecosystems, and a limited amount of arable lands. It is one of the most water-scarce regions in the world. The region is heterogeneous in terms of the countries' economies, but because it includes some of the richest and some of the poorest countries in the world, regional average economic performance statistics are misleading. The region is mostly semi-arid and arid, with significant areas of extreme aridity. These areas are further challenged by extreme temperatures, frequent drought, land degradation, and desertification. Recent changes in climate patterns, such as prolonged droughts, record temperatures, and increased rainfall irregularity, intensity and distribution, have all further negatively impacted the natural and agro-ecosystems in the region. Such changes have led to increased vulnerability of the people dependent on such resources for their livelihood. This article focuses on the impact of land desertification due to climate changes on the prevailing natural resources, and discusses several approaches for mitigating or alleviating desertification. It is clear that water shortage is a problem in many countries of this predominantly arid region, and is unlikely to be reduced and may be exacerbated by climate change. Proposed adaptation strategies might include more efficient organization of water supplies, treatment, and delivery systems, and increased use of groundwater. It is necessary to develop alternative production and management systems appropriate to the socioeconomic and environmental conditions in order to prevent further degradation of the prevailing agro-ecosystems and sustain the livelihoods of farmers living in marginal conditions. Grasslands, livestock, and water resources are likely to be most vulnerable to climate change in the region because they are located mostly in marginal areas. Changes in cropping practices and improved irrigation practices, and introducing proper livestock-fodder crop production integrated systems, could significantly enhance water use efficiency, eliminate the impact of desertification, and improve local livelihoods.Hassan M.El Shaer 2015Research in Cold and Arid Regions2015,7,1:3

12Childhood glaucoma profile in Dakahelia, Egypt: a retrospective study显示文摘AIM: To analyze childhood glaucoma regarding its demographics, presentations, different causes and surgical modalities used among patients in Dakahelia and to apply the Childhood Glaucoma Research Network(CGRN) classification retrospectively to evaluate its convenience.METHODS: A retrospective study in which the medical files of all glaucoma patients <16 years old presented to Mansoura Ophthalmic Center, Mansoura University from 2014 to 2017, were retrieved and analyzed. Collected data included: age, gender, laterality, visual acuity(VA), refraction, intraocular pressure(IOP), corneal diameter, cup-disc ratio, types and number of surgeries and antiglaucomatous drugs(AGD) at the first and last visit. Prevalence of different subtypes was calculated and means of clinical features were compared.RESULTS: A total of 305 eyes of 207 patients were included classified into 6 groups: primary congenital glaucoma(PCG), juvenile open angle glaucoma(JOAG), glaucoma associated with systemic disease, glaucoma associated with ocular anomalies, acquired glaucoma and glaucoma following cataract surgery. PCG was the predominant type(55.1%) followed by acquired glaucoma(29.5%). Males represented 63.8% of the whole studied patients. Glaucoma associated with ocular anomaly group showed the youngest age at diagnosis(21.9±30.0 mo). The shortest corneal diameter was recorded in post cataract group(10.4±0.5 mm). Highest cup-disc ratio was found in the PCG group(P<0.0005). Glaucoma associated with systemic disease presented with the highest baseline IOP(34.5±5.0 mm Hg). All the cases with PCG were treated surgically with 21.8% required more than one surgery. The majority of the patients(74.2%) in the acquired group were treated medically. Combined trabeculotomy-trabeculectomy was the most frequent operation done, accounting for 34.5% of all primary surgeries. Ahmed valve implantation comprised 87% of the secondary surgeries. Acquired glaucoma group had the highest percent of eyes with good final Snellen's VA(69.4%), while glaucoma associated with ocular anomaly group had poorest final VA. CONCLUSION: PCG is the most prevalent type of childhood glaucoma, followed by acquired glaucoma especially traumatic hyphema. Combined trabeculotomytrabeculectomy and Ahmed valve implantation are the most common surgical interventions. CGRN classification is found to provide a consensus skeleton and is recommended to be integrated in our routine ongoing clinical practice.Tharwat H.Mokbel Eman M.El Hefney Sherein M.Hagras Ahmed A.ALNagdy Amani E.Badawi Manal A.Kasem Shereen M.El Shaer 2018International Journal of Ophthalmology(English edition)2018,11,4:1
