Background and Objectives: Recently, continuous veno-venous hemodiafiltration (CVVHDF) has received increased attention in the treatment of congestive heart failure (CHF). The aim of this study is to assess the safety and efficacy of CVVHDF compared with intravenous furosemide in patients with CHF. Methods: Forty patients having CHF were included in this prospective, randomized, comparative trial. We randomized patients to treatment for 72 hours with CVVHDF or intravenous furosemide. Outcomes assessed were weight loss, total fluid output, length of stay (LOS) in the intensive care unit (ICU), 30-day mortality, and cardiovascular stability. Results: Demographic data were comparable in both groups. Weight loss (P ≤ .05) and total fluid output (P ≤ .01) were greater in the CVVHDF group. Length of stay in the ICU was significantly reduced in the CVVHDF group (P ≤ .05). The mortality rates were comparable in both groups. The cardiac output and the stroke volume significantly increased, whereas the pulmonary capillary wedge pressure significantly decreased (P ≤ .05) in both groups compared with the baseline. A transient attack of hypotension occurred in 1 patient in the CVVHDF group. Conclusion: In CHF, the use of CVVHDF effectively and safely produced greater weight and fluid loss and decreased LOS in the ICU more than the intravenous furosemide with no hemodynamic instability. © 2012 Elsevier Inc.

The mining work at El-Gedida iron mine, El-Bahariya Oasis, in the Western Desert of Egypt extracts commercial iron ore deposits without attention paid to the large glauconite deposits overlying these iron ore deposits. For this reason, the present paper aims at evaluating and attracting the attention to these glauconite deposits as alternative potassium fertilizers. The study was achieved by investigating mineralogical, physical and chemical properties of the green deposits. Mineralogical and physical properties involved the determination of glauconite pellets content in different grain size fractions relative to impurities and the analysis of the percentage of clay matrix and grain size distribution. Different pre-treatment strategies and methods including comminution, sieving, magnetic separation, and X-ray diffraction were used for investigating those mineralogical and physical properties. On the other hand, chemical analyses included potassium content, heavy metal concentrations, and pH and salinity measurements. The major elements and trace elements were measured using ICP-OES and the pH was measured using a pH conductometer. Moreover, this study investigated the nature of grain boundaries and the effect of sieving on glauconite beneficiation. Results of this study suggest that El-Gedida glauconite deposits are mineralogically, physically and chemically suitable for exploitation and can be beneficiated for use as an alternative potassium fertilizer. © 2016 Elsevier Ltd.

Background Trigeminal neuralgia or tic douloureux is sometimes described as the most excruciating pain known to humanity. Objectives To estimate the prevalence of trigeminal neuralgia among the population of Al-Quseir city. Methods This study forms a part of door to door survey of major neurological disorders in Al-Quseir city, Red sea governorate, Egypt. The total population (33,285 persons) were screened through door to door (every door) by three specialists of Neurology and fifteen female social workers. Then, positive cases were subjected to clinical and neurological examination by other three staff members of neurology. Cases were identified as suffering from trigeminal neuralgia according to the diagnostic criteria of the International headache society (IHS). Results We identified 4 female patients out of 13,541 persons (aged 30 years and more) suffering from trigeminal neuralgia with age specific prevalence rate of 29.5/100,000. Co-morbid depression and hypertension were observed among the affected persons. © 2013 Elsevier B.V.

Objectives: Febrile neutropenia (FN) is a common adverse effect of chemotherapy. Current management of FN is expensive and may induce side effects. Honey, as a natural honeybee product, has antioxidant, antimicrobial, immunomodulator and anticancer effects. Additionally, honey is not expensive. The aim of this study is to test the effects of a 12-week honey consumption on children with acute lymphoblastic leukemia (ALL) particularly with regard to FN. Design: A randomized crossover clinical trial. Forty patients of both sexes, aged 2.5-10 years, were randomized into two equal groups [intervention to control (I/C) and control to intervention (C/I)]. Setting: Children Hospital of Ain Shams University-Cairo-Egypt. The dietary intervention consisted of honey in a dose of 2.5 g//kg body weight per dose twice weekly for 12 weeks. Main outcome measure: Febrile neutropenia in terms of frequency and duration of hospital admission. Results: The intervention resulted in a significant decrease of FN episodes, the number of patients admitted with FN and the duration of hospital stay. Also, honey consumption improved the levels of hemoglobin and did not produce any serious side effect. As a possible effect of honey withdrawal in the I/C group, the Hb%, the absolute neutrophil count and the platelet count decreased. Conclusion: Honey intervention in a group of children with ALL resulted in positive effects on FN and hematologic parameters. Further studies that include a larger number of patients are recommended to confirm that honey, has beneficial effects, as a complementary agent, in children with ALL. © 2016 Elsevier Ltd.

All IP networks become increasingly visible. The various communication networks are aimed to be connected with each other through a common IP core, so that the user will stay always online, anytime and anywhere. However a lot of challenges remain unsolved until today. One of the major challenges is how to achieve a seamless and fast handoff while moving from one point off attachment to another. In this paper we propose a new fast and smooth handoff approach called Pre-MIFA (pre registration mobile IP fast authentication protocol). Pre-MIFA uses the layer 2 trigger to eliminate the latency resulting from the agent discovery procedure (pre-registration method), and the MIFA procedures to eliminate the latency resulting from the communication between the foreign agent and the home agent especially when the home gent is far a way from the foreign agent. Our approach minimizes the handoff latency without introducing intermediate node and without making any restriction on network topology.we also present a simple program analysis comparing the hand off latency of MIP, MIFA, Pre-Registration and our approach. Our results have shown that Pre-MIFA outperforms Pre-Registration method, MIP and MIFA with respect to handoff latency.
