About 40-70% of the infections caused by Staphylococcus aureus strains are due to methicillin resistant ones. These isolates are usually multi-drug resistant and harder to treat endangering hundreds of thousands of patients worldwide and costing billions in added health care costs. Accurate numbers describing the prevalence and characteristics of these infections and the added burden they cause to developing countries in the eastern Mediterranean and African regions are lacking. Egypt is no exception. In this article that appeared in Infectious Disorders - Drug Targets, Dr. AlaaAbouelfetouh, Associate Professor of Microbiology at the Faculty of Pharmacy, Alexandria University, is gathering the published data describing methicillin resistance in S. aureus (MRSA) in Egypt. The reports described a general MRSA prevalence rate of 50-82% among hospitalized patients mainly in the largest two Egyptian cities Cairo and Alexandria and a lower rate of 24% in Minia, an important but less populated city in southern Egypt. The articles that investigated community acquired MRSA reported 19-47% prevalence. Some of these studies molecularly characterized the types of the MRSA isolates using different techniques; SCCmec typing, or spa typing and Multi-locus sequence typing (MLST). SCCmec types V, IV and its subtypes were detected in two separate studies. A different study revealed a MRSA prevalence rate among retail chickens of 38% which could act as reservoir for resistance transfer to humans. "Although the numbers point to an increasing rate of MRSA occurrence, especially in large cities such as Cairo and Alexandria, in the absence of a national surveillance program it is not possible to extrapolate these results to cover the whole country", warns Dr. Abouelfetouh. Despite these alarming levels of MRSA in hospital and community settings, awareness of MRSA control measures among the medical staff at one of the major health centers in Egypt was at the 67% level.

The scientific targets of the EUROSUNMED project are the development of new technologies in three energy field areas, namely photovoltaics (PV), concentrated solar power (CSP) and grid integration (GI), in strong collaboration with research institutes, universities and SMEs from Europe in the north side of the Mediterranean sea and from Morocco and Egypt from the south of the sea. The focus in PV will be on thin film (Si, CZTS) based solar cells and modules while the goal in CSP field is to design and test new heliostats as well as novel solutions for energy storage compatible with these technologies. The project aims at producing components that will be tested under specific conditions of MPC (hot climate, absence of water, etc.). Such investigations are complemented with studies on grid integration of energy sources from PV and CSP in Morocco and Egypt context. Additionally, the consortium envisages to train PhD students and Post-Docs in these interdisciplinary fields in a close and fruitful collaboration between academic institutions and industry from EU and MPCs. The consortium is well placed around leading academic groups in materials science and engineering devices and equipments for the development of PV and CSP, and also in the promotion of the renewable energies in general. Moreover, technology transfer and research infrastructure development in the targeted areas will be provided. Disseminating the results of the projects will be done through the organization of summer schools, workshops and conferences towards large public from universities, engineering schools and stakeholders involved in the three selected energy areas and beyond. Another outreach of the project will be the proposal for a roadmap on the technological aspects (research, industry, implementation) of the PV, CSP and grid area as well as on the best practice for the continuation of strong collaboration between the EU and MPCS partners and beyond for for mutual interest and benefits.

BACKGROUND: The modified Karydakis flap and the modified Limberg flap are commonly used in the surgical management of sacrococcygeal pilonidal sinus disease. OBJECTIVE: The study aimed to compare short- term results of these techniques. DESIGN: The modified Karydakis flap and the modified Limberg flap were compared in a randomized controlled trial. SETTINGS: The study was conducted in the day-case surgery department of a large academic teaching hospital in Alexandria, Egypt, from February 2009 through September 2011. PATIENTS: Patients undergoing surgery for chronic sacrococcygeal pilonidal sinus disease were eligible for the study. Patients with sepsis were eligible only after aggressive treatment to eliminate sepsis. INTERVENTIONS: Patients were randomly allocated to undergo surgery with either the modified Karydakis flap or the modified Limberg flap. MAIN OUTCOME MEASURES: The primary end point was operative time. Secondary endpoints included proportion of patients with postoperative complications, proportion of patients who were satisfied with the cosmetic results, and the rate of recurrence. LIMITATIONS: Follow-up times were not sufficient to evaluate long-term recurrence rates. RESULTS: Of 154 patients screened, 125 were enrolled, and 120 patients completed the study. The median operative time was significantly shorter in patients with the modified Karydakis flap than in those with the modified Limberg flap: 33 (range, 28-40) min vs 52 (range, 48-62) min; p < 0.001). No significant differences were found between study groups regarding overall complication rate (23% vs 40%, p = 0.08), wound infection (3% vs 5%, p > 0.99), subcutaneous fluid collection (5% vs 0%, p = 0.24), or hypoesthesia (10% vs 23%, p = 0.09). Full-thickness wound disruption was encountered in 9 patients (15%) in the modified Limberg group vs no patient in the modified Karydakis group (p = 0.003). The median follow-up duration was 20.5 months in each study group. One patient (2%) in the modified Karydakis group developed recurrent disease vs 2 patients (3%) in the modified Limberg group (p > 0.99). In the modified Karydakis group, 58 patients (97%) were satisfied with the cosmetic outcome and were willing to recommend the operation to others vs 43 patients (72%) in the modified Limberg group (p < 0.001). CONCLUSIONS: Both techniques provide effective treatment for pilonidal sinus disease and can be performed safely as day-case surgery. The modified Karydakis flap is associated with significantly shorter operative time, a lower full-thickness wound disruption rate, and a higher patient satisfaction rate. © The ASCRS 2013.

Purpose We sought to determine the incidence of erectile dysfunction following pelvic fracture urethral injuries in children, and to identify the related causes and risk factors. Materials and Methods All consecutive children who had undergone repair of a pelvic fracture urethral injury between 1980 and 2010 were invited to participate in the study. All responders were queried after a median of 13 years (range 3 to 28) following trauma to assess erectile function using the erectile function domain of the International Index of Erectile Function. Patients who had erectile dysfunction underwent penile duplex ultrasonography. Medical records and imaging studies were reviewed with a focus on 4 variables, ie pattern of pelvic fracture, pubic diastasis, prostatic displacement and urethral gap length. Univariate and multivariate analyses were used to identify parameters predictive of erectile dysfunction at puberty. Results A total of 60 patients participated in the study, of whom 28 (47%) had erectile dysfunction. On univariate analysis all 4 parameters were significant predictors of erectile dysfunction, while on multivariate analysis only 2 parameters remained strong and independent predictors, namely urethral gap length 2.5 cm or greater and prostatic displacement in a lateral direction. Duplex ultrasound revealed the cause of erectile dysfunction as arteriogenic in 19 patients (76%), arteriovenogenic in 2 (8%) and likely neurogenic in 4 (16%). Conclusions For every 2 children sustaining a pelvic fracture urethral injury 1 will exhibit erectile dysfunction at puberty. The risk of erectile dysfunction is appreciably increased in the presence of a long urethral gap and/or lateral prostatic displacement. The cause of erectile dysfunction is most commonly primarily arteriogenic and less commonly neurogenic. © 2014 by American Urological Association Education and Research, Inc.
