Geophysical investigations of a geothermal anomaly at Wadi Ghadir, eastern Egypt

During regional heat flow studies a geothermal anomaly was discovered approximately 2 km from the Red Sea coast at Wadi Ghadir, in the Red Sea Hills of Eastern Egypt. A temperature gradient of 55 C/km was measured in a 150 m drillhole at this location, indicating a heat flow of approximately 175 mw/sqm, approximately four times the regional background heat flow for Egypt. Gravity and magnetic data were collected along Wadi Ghadir, and combined with offshore gravity data, to investigate the source of the thermal anomaly. Magnetic anomalies in the profile do not coincide with the thermal anomaly, but were observed to correlate with outcrops of basic rocks. Other regional heat flow and gravity data indicate that the transition from continental to oceanic type lithosphere occurs close to the Red Sea margin, and that the regional thermal anomaly is possibly related to the formation of the Red Sea

Implementation of a bowel management program in the treatment of incontinence in children for primary healthcare providers

Objectives: Our surgical team has devised a bowel management program (BMP) as a basic approach for primary healthcare providers with the least use of resources.Background: Soiling in children is a major problem that has a serious impact on the child’s social and psychological life. Causes vary from idiopathic constipation to postoperative or neuropathic causes as meningomyelocele.Participants and methods: Seventy five children suffering from fecal incontinence were assessed and divided into true incontinence and pseudoincontinence groups. The BMP was applied to both categories in the form of proper diet control, enemas, drugs, and bowel habit alteration. The program was fashioned according to the age, type, severity, and response of each case. A fecal incontinence scoring system was used to assess the results.Results: All cases with pseudoincontinence attained 50% or more improvement in incontinence score whereas the true incontinence cases attained excellent results except in post high anorectal malformation repairs and neurologic groups.Conclusion: Most of the cases suffering from constipation with pseudoincontinence can be treated properly by BMPs, whereas the minority suffering from true incontinence need multidisciplinary work to achieve acceptable results.Keywords: anorectal malformations, bowel management program, chronic idiopathic constipation, fecal incontinence, Hirschsprung’s disea

EVALUATION OF FOOD TYPE INTRODUCED TO THE HONEYBEE COLONIES ON CONTAMINATION OF EXTRACTED HONEY WITH MICROORGANISMS

The aim of the present work to study the effect of foodtypes (sugar syrup fortified with Garlic (Allium sativum), Lemon (Citrus limon), Garlic plus Lemon), pollen grains and plain sugar syrup (1:1)) on contamination of honey with bacteria, fungi and yeasts. The data indicated that application of sugar syrup plus extracts of garlic, lemon, garlic plus lemon or bee pollen led to decrease population of bacteria, fungi and yeasts compared with control treatment (plain sugar syrup 1:1). The fungi were the least population in all the treatments compared with bacteria and yeasts, meanwhile population of bacteria were moderately and the yeasts were the most occurrence. Garlic plus lemon treatment was the most effective against population of microorganisms, but garlic and lemon separate were moderately effective and bee pollen treatment was the least effective compared with other treatments. According to isolation and identification procedures, three bacterial species (Bacillus brevis, Bacillus cereus and Clostridium botulism), four fungal species (Aspergillus apis, Aspergillus niger, Cladosporium sp. and Penicillium sp.) and three yeasts species (Debaromyces sp., Lipomyces sp. and Saccharomyces sp.) were determined according to cultural, morphological and physiological characters. Cladosporium botulism bacterium was the most frequency compared with other bacteria species, but Aspergillus apis fungus was the most frequency compared with other fungi species and Lipomyces sp. was the most frequency compared with other yeasts

Islamophobia and Proximities to Whiteness: Organizing Outside of the Brown Muslim Subject

The existing Islamophobia 1 literature has come to illustrate how the Muslim subject “can at a moment’s notice be erected as [an] object of supervision and discipline” ( Morey and Yaqin 2011 : 5–6). In the popular imagination, Muslimhood 2 has come to stand for an undifferentiated culturally alien oriental subject defined through the prism of racialized violence and irrationality. Although much of the anti-Islamophobia efforts – academic and community-based – work to combat the reductiveness of a universalized Muslim figure , these efforts tend to uncritically take up the brown Muslim figure as the starting point of inquiry, thereby further reifying the homogenizing racialization of dominant discourses. This article opens up the possibilities to expand thinking on the lifeworld of Islamophobia by addressing the erasure that happens with this homogenizing approach to Islamophobia. In particular, we consider the dialogical nature between the operational life of Islamophobia and the differing proximities to whiteness our intersectional subject positions make available. And in turn, how these availabilities come to shape the experience of Islamophobia is a prime focus of analysis. The authors ask: how does the systemic demarcation of Muslim subjectivity, across racial, ethnic, class, regional, and ideological lines, interact with how Islamophobia is experienced and operationalized? Leveraging an auto-ethnographic approach, we provide first-person narratives of Islamophobic encounters from our respective geopolitical and social locations to deconstruct and delineate an intersectional understanding of Islamophobia

Direct cord implantation in brachial plexus avulsions: revised technique using a single stage combined anterior (first) posterior (second) approach and end-to-side side-to-side grafting neurorrhaphy

<p>Abstract</p> <p>Background</p> <p>The superiority of a single stage combined anterior (first) posterior (second) approach and end-to-side side-to-side grafting neurorrhaphy in direct cord implantation was investigated as to providing adequate exposure to both the cervical cord and the brachial plexus, as to causing less tissue damage and as to being more extensible than current surgical approaches.</p> <p>Methods</p> <p>The front and back of the neck, the front and back of the chest up to the midline and the whole affected upper limb were sterilized while the patient was in the lateral position; the patient was next turned into the supine position, the plexus explored anteriorly and the grafts were placed; the patient was then turned again into the lateral position, and a posterior cervical laminectomy was done. The grafts were retrieved posteriorly and side grafted to the anterior cord. Using this approach, 5 patients suffering from complete traumatic brachial plexus palsy, 4 adults and 1 obstetric case were operated upon and followed up for 2 years. 2 were C5,6 ruptures and C7,8T1 avulsions. 3 were C5,6,7,8T1 avulsions. C5,6 ruptures were grafted and all avulsions were cord implanted.</p> <p>Results</p> <p>Surgery in complete avulsions led to Grade 4 improvement in shoulder abduction/flexion and elbow flexion. Cocontractions occurred between the lateral deltoid and biceps on active shoulder abduction. No cocontractions occurred after surgery in C5,6 ruptures and C7,8T1 avulsions, muscle power improvement extended into the forearm and hand; pain disappeared.</p> <p>Limitations include</p> <p>spontaneous recovery despite MRI appearance of avulsions, fallacies in determining intraoperative avulsions (wrong diagnosis, wrong level); small sample size; no controls rule out superiority of this technique versus other direct cord reimplantation techniques or other neurotization procedures; intra- and interobserver variability in testing muscle power and cocontractions.</p> <p>Conclusion</p> <p>Through providing proper exposure to the brachial plexus and to the cervical cord, the single stage combined anterior (first) and posterior (second) approach might stimulate brachial plexus surgeons to go more for direct cord implantation. In this study, it allowed for placing side grafts along an extensive donor recipient area by end-to-side, side-to-side grafting neurorrhaphy and thus improved results.</p> <p>Level of evidence</p> <p>Level IV, prospective case series.</p

Hepatitis C-Associated Chronic Lymphoproliferative Disorders: A Single Center Experience

Hepatitis C virus (HCV) infection is a major public health concern in Egypt with its unique genotype. Besides liver disease, HCV is a lymphotropic virus involved in the pathogenesis of various extrahepatic diseases. A causative role of HCV in the generation of chronic lymphoproliferative diseases as well as its impact on disease behavior in HCV chronic carriers are not fully understood. We investigated the prevalence of HCV among cohort of Egyptian patients (n:84) with chronic lymphoproliferative diseases, the relation between HCV infection and the immunological state of this opulation and also their clinical and laboratory characteristics. High prevalence of HCV (40%) among Egyptian patients with chronic lymphoproliferative diseases with following subtype frequency was revealed; CLL (38.2%) followed by DLBCL (20.6%), and LPL (17.6%). We found significant correlation between HCV and platelet count (P=0.014), Albumin (P=0.02), LDH (P=0.014) and B2M (P=0.05). Otherwise, there were no significant correlations with other parameters especially the immunological assessment; serum immunoglobulins, Coombs test, and cryoglobulinemia. HCV prevalence among patients with chronic lymphoproliferative diseases is higher than that estimated in the general population. Those patients should be tested for HCV during the assessment. Our observations suggest that HCV may have an oncogenic role in Egyptian patients with chronic lymphoproliferative diseases and it may affect the prognostic markers in those populations

Fatal bilateral pneumonitis after locoregional thoracic chemoradiation in a transplanted patient under immunosuppressive therapy

Background: After thoracic radiotherapy a pneumonitis may occur, mostly confined to the irradiated volume of the lung. In general, it resolves spontaneously without long-term effects. Case Report: A 68-year-old man was diagnosed with a stage IIIA adenocarcinoma of the lung and was treated with sequential chemoradiation. He had a heart and kidney transplant for which an immunosuppressant was taken. During the fourth week of radiotherapy, he developed a bilateral interstitial pneumonia. Despite antibiotics and steroids, the patient died twelve days after the onset of complaints due to respiratory failure. Autopsy showed in all pulmonary lobes extensive diffuse alveolar damage, probably leading to respiratory insufficiency and death. Literature and Conclusion: Bilateral pneumonitis after radiotherapy is thought to be an immunologically-mediated response, which usually resolves without long-term effects. Since in radiation pneumonitis an increase in T-cells is described, the suppression of these cells by an immunosuppressant might have exaggerated the pulmonary toxicity
