Abstract: Background: Acute pancreatitis is one of the most serious complications of ERCP. Early diagnosis of post ERCP pancreatitis helps physicians to provide intensive care and possible medical treatment as early as possible. Trypsinogen-2 in urine is a good diagnostic and prognostic marker of acute pancreatitis. Objectives: To evaluate the diagnostic value of urinary trypsinogen-2 dipstick test for early diagnosis of post ERCP pancreatitis. Methods: A total of 37 patients with obstructive jaundice were tested with the urinary trypsinogen-2 dipstick test and serum levels of amylase and lipase before ERCP and 6 hours after ERCP. Results: Post ERCP pancreatitis was diagnosed in 6 (16%) of 37 patients. The sensitivity, specificity, positive predictive value and negative predictive value of urinary trypsinogen-2 dipstick test at 6 hours after ERCP were 100%, 97%, 86%, 100% respectively. At the cutoff level (130 U/L) for lipase, the positive predictive value and negative predictive value all were (100%), however, the positive predictive value and negative predictive value for amylase levels at cutoff (122 U/L) were 60%, 100% respectively. Serum lipase level was the best test for diagnosing post ERCP pancreatitis followed by the urinary trypsinogen-2 dipstick test. Conclusions: The urinary trypsinogen-2 dipstick test can be used as a rapid and easy test for early diagnosis of post ERCP pancreatitis with high sensitivity and specificity.

Open Journal of Rheumatology and Autoimmune Diseases (OJRA) , 2012, DOI: 10.4236/ojra.2012.22002
Abstract: Adult Still’s disease is a relatively rare form of rheumatoid arthritis with systemic inflammatory features. The prevalence is around 1.5 cases per 100,000 - 1000,000. In the current case we display a 30-year-old male patient with refractory adult still’s disease who suffered recurrent attacks of fever 39.5°C, arthritis in proximal interphalangeal joints (PIPs), wrists, tempromandibular joints (TMJs), knees and ankles, stitching chest pain, dyspnea, erythematous rash over the trunk, sore throat, weight loss (15 Kilograms in 4 months). The patients’ disease remained uncontrolled despite of synthetic disease modifying anti-rheumatic drugs and repeated intramuscular corticosteroid injections. Laboratory workup revealed erythrocyte sedimentation rate (ESR) of 95, C-reactive protein (CRP) of 100 mg/L, hemoglobin 10.5 gm%, leukocytosis 12,000/microlitre, mild elevation of liver function tests and dyslipidemia. Serology revealed negative rheumatoid factor, anti-nuclear antibody titre of 1:80, elevated serum ferritin 4000 micrograms/litre. The patient was started on rituximab (375 mg/m2), prednisolone 20 mg/day and selective Cox-2 inhibitor. Follow up for over three months following the completion of his pulse therapy, revealed no relapse of fever or fatigue, with morning stiffness of 5 - 10 minutes, VAS of 3, DAS28 of 3.8, HAQDI of 0.62, ESR 23, CRP 4.9, Hb 12.5 gm%, leucocytic count 9000/microlitre, the dose of prednisolone was successfully reduced to a dose of 5 mg/day orally. Conclusion: Anti-CD20 therapy successfully controlled systemic and articular refractory disease with sustained efficacy over a follow up period of up to 24 weeks.

Abstract: The northern Egyptian continental margin is characterized by interesting tectonic settings as well as trade and industry district in Egypt. In the current study, the contribution role of satellite altimetry gravity data in the Environmental geophysical investigation is presented to give a complete view of the marine gravity field of the study area. The satellite data showed only minor deviations in some partial regions of the area investigated such as Nile Deep Sea Fan, Levant Basin, Eratosthenes Seamount and Herodotus basin. The interpretations of the entire data illustrated that the differences between the satellite and the shipboard data were small in some regions particularly near to land. Furthermore, a number of strong deviations in some regions were spatially correlated with bathymetric depth together with the appearance of geological structures.
Immersive Learning Design (ILD): A New Model to Assure the Quality of Learning through Flipped Classrooms  [PDF]
Hamdy A. Abdelaziz
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.211027
Abstract: The objective of this paper was to develop an immersive Web-based learning model to assure the quality of learning through the flipped classrooms. The proposed model was guided theoretically by the flipped classroom as a new Web-based learning trend/system. It was also guided pedagogically by active and reflective learning principles that support transforming of the teaching and learning practices from content engagement to cognitive engagement. The targeted immersive learning model encompasses four reciprocal phases: Pro-act, Act, Reflect, and Re-act (PARR). To validate the suggested model, a convenience sample of graduate students studying an advanced statistics course was selected from the Distance Teaching and Training Program at Arabian Gulf University. After designing and applying this new immersive Web-based learning model (PARR), findings revealed that using the flipped classroom through this immersive Web-based learning model has a statistical and practical impact on developing achievement and self-study skills among graduate students. The contribution of this research is that it qualifies the Web-based instructional practices to shift from content acquisition act to knowledge expression and creation act. In addition, the paper will be of benefit to people looking for pedagogical applications of virtual and blended learning environments for developing multiple ways to express what learners know and be able to do.

Open Journal of Modern Neurosurgery (OJMN) , 2018, DOI: 10.4236/ojmn.2018.81008
Abstract: An aggressive separation and prolonged overstretching of the paraspinal muscles in the posterior midline approach during lumbar non fusion dynamic stabilization in cases of spondylolisthesis resulting from pars interarticularis fracture may result in postoperative flat back deformity and intractable chronic pain. It is hypothesized that utilizing Wiltse paraspinal inter-muscular approach for this purpose may result in reduction of operative time, protection of integrity, vascularity, nerve supply and strength of paraspinal muscles, shortening of hospitalization and minimizing development of chronic postoperative back pain. So, I have performed this prospective descriptive study that involved 24 patients having single level lumbar instability at L4-5 or L5-S1 levels. All patients were operated upon using Wiltse minimal access posterolateral surgical technique for non-fusion dynamic stabilization. The final results revealed that males were 66%, females were 33% and ages were 42 ± 6 years. Trauma was reported in 12%. Low back pain and tenderness were reported in 100% and root affection reported in 25%. Plain X-ray and MRI were done in 100% and C.T. was done in 8% of cases. Level L4-5 was affected in 17% while level L5-S1 was affected in 83%. Anterolisthesis grades 0 was found in 8%, grades 1 in 88% and retrolisthesis in 4% of cases. Operative time was 1 hour ± 10 min., blood loss was 60 ± 20 ml., patients ambulation was after 6 - 8 hours, hospital stay was 12 - 24 hours. None of cases were complicated with infection, screw loosening, or fixation system break. Back pain VAS diminished from 7 preoperative to 5 in 2nd day, then became 4 by 1 week, 3 by 1 month and 0 by 6 months. It was concluded that utilizing Wiltse approach for posterolateral lumbar stabilization minimizes tissue damage and improves the speed of recovery and outcome.

Abstract: Chronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions occurring mostly in elderly and ideally treated with surgical drainage. Many surgical techniques of different degrees of invasiveness have been proposed for its treatment with controversy about the best surgical procedure. The study aims to evaluate the efficacy of the minimal access technique of single burr-hole craniostomy and massive irrigation for treatment of unilateral CSDH. The study is a prospective descriptive study involved all patients with symptomatic radiologically proven unilateral CSDH admitted and treated surgically in department of Neurosurgery, Al-Hussein University hospital, Al-Azhar University, Cairo, Egypt, over 3 years, from January 2013 to January 2016. In the results we found that total 64 patients of CSDH, treated surgically by this procedure. Men formed 72% and women 28%. Age range was 51 to 82 years; the mean age was 65 years. Clinical presentation was impaired consciousness in 7%, headache (59%), right hemiparesis in 56% and left hemiparesis in 37%. CT was done for 91% and MRI 27% patients. The hematoma was left in 61% and right in 39%. Surgical evacuation utilizing this procedure was done in all patients. Complete recovery was obtained in 82% of patients and partial recovery in 11% of patients. Follow up for 4 months was done. Recurrence was detected in 6% of patients. We concluded that unilateral CSDH can be treated effectively by single nondependent burr-hole craniostomy and massive irrigation with excellent outcome.

Neuroscience & Medicine (NM) , 2018, DOI: 10.4236/nm.2018.91001
Abstract: Carpal tunnel syndrome is one of the commonest entrapment neuropathies. Hand pain and numbness are mostly the presenting symptoms. Endoscopic carpal tunnel release (ECTR) has been demonstrated to reduce recovery time and allow faster return to the work. The purpose of this prospective descriptive study was to evaluate the efficacy and advantages of (ECTR) through single proximal incision. In this study, the procedure was done for 36 hands in 36 patients. The results showed that females:male = 9:1, mean age was 42 years. Right hand dominance was 90% and affected in 67%. Preoperatively, the condition was moderate in 61% and severe in 39%. The average operating time was 10 minutes and the mean follow up period was 6 months with no major postoperative complications. In 8%, transient neurapraxia was found and resolved in 1 week and tenderness was found in 70% and resolved in 4 weeks. we concluded that endoscopic carpal tunnel release is an effective minimal incisional safe procedure with a high success rate, rapid return to work.
Microstructure, Corrosion, and Fatigue Properties of Alumina-Titania Nanostructured Coatings  [PDF]
Ahmed Ibrahim, Abdel Salam Hamdy
Journal of Surface Engineered Materials and Advanced Technology (JSEMAT) , 2011, DOI: 10.4236/jsemat.2011.13015
Abstract: Air Plasma spray process was used to deposit a conventional and nanostructured Al2O3-13 wt% TiO2 coatings on a stainless steel substrates. Morphology of the powder particles, microstructure and phase composition of the coatings were characterized by XRD and SEM. Potentiodynamic polarization tests and Electrochemical Impedance Spectro- scopy (EIS) were used to analyze the corrosion of the coated substrate in 3.5% NaCl solutions to determine the opti-mum conditions for corrosion protection. The fatigue strength and hardness of the coatings were investigated. The experimental data indicated that the nanostructured coated samples exhibited higher hardness and fatigue strength compared to the conventional coated samples. On the other hand, the conventional coatings showed a better localized corrosion resistance than the nanostructured coatings.
Stroke volume estimation by thoracocardiography is better when glottis is closed
Enas Abdulhay,Pierre Baconnier
Quantitative Biology , 2008, DOI: 10.1109/IEMBS.2007.4352481
Abstract: Thoracocardiography approach pretends to non-invasively monitor stroke volume by inductive plethysmographic recording of ventricular volume curves by a transducer placed on the chest. The purpose of this study was to investigate the potential of thoracocardiography to estimate stroke volumes while apnea with open glottis. We hypothesized that, when glottis is open, stroke volumes would be better estimated if airways flow curves were taken into account.
The Organ Transplant Debate in Egypt: a Social Anthropological Analysis Le débat sur les greffes d’organe en égypte : analyse anthropologique
Sherine Hamdy
Droit et Cultures , 2010,
Abstract: In this paper, I take the heated debate about the ethics of organ transplantation in Egypt, to ask why Egypt is the only Muslim country in the world that has, for the past three decades, been unable to pass legislation for a national organ transplant program. Why is it that patients and even physicians articulate their antipathy to organ transplantation in terms of “Islam” when most Muslim scholars of Islamic law have argued that the donation of organs is permissible? I argue that we cannot reduce the question of the ethics of organ donation in Egypt to abstract Islamic legal categories (permissible (mubah) or impermissible (haram) – as analysts both within and outside the Muslim world are apt to do. Doing so overlooks the pervasive problem of social inequalities that persist in the Egyptian medical system. In the context of vast discrepancies in health status and health care delivery, ordinary Egyptians are wary of medical institutions’ claims of re-using body parts for the common good. Cet article traite du débat sensible sur l’éthique de la greffe d’organe en égypte et s’interroge sur la question du pourquoi l’égypte est le seul pays musulman dans le monde qui a, durant ces trois décennies, été incapable de faire passer une législation pour un programme de transplantation nationale. Pourquoi les patients et même les médecins formulent-ils leur antipathie à la transplantation d’organes en termes d’ islam quand la plupart des érudits musulmans ont établi que le don d’organe était possible ? Je soutiens qu’on ne peut réduire la question de l’éthique du don d’organe en égypte à des catégories juridiques islamiques abstraites comme le licite (mubah) ou l’illicite (haram) – ainsi que le font des analyses provenant à la fois de l’intérieur et de l’extérieur du monde musulman. Ce faisant, on néglige le problème majeur des inégalités sociales qui persistent dans le système médical égyptien. Dans un contexte de dépenses de santé déficitaires, les égyptiens hésitent beaucoup face aux demandes des institutions médicales à utiliser des parties de leur corps pour l’intérêt commun.
