Nephrotic Syndrome Revealing of a Squamous Cell Bronchial Carcinoma
No full textMalignant broncho-pulmonary tumors are the principal cause of the paraneoplastic nephrotic syndrome. These tumors are most often small cell or squamous bronchial carcinomas. In 75% of cases, the nephrotic syndrome is due to membranous glomerulonephritis. We report the case of a 67 years old patient, a chronic tobacco user, followed since June 2019 for a nephrotic syndrome caused by extra-membranous glomerulonephritis. A chest computed tomography revealed a mass of the left lower lobe. Trans-parietal biopsy of this process revealed a squamous bronchial carcinoma. PET scan detected no other fixations. The proteinemia was at 39g/l with albuminemia at 14 g/l. Surgical resection was then indicated and the patient underwent a left lower lobectomy with radical lymph adenectomy. Outcomes were simple with complete resolution of paraneoplastic nephrotic syndrome
The Endobronchial Inflammatory Myofibroblastic Tumor
No full textThe inflammatory myofibroblastic tumor is a rare tumor described in the literature as a type of inflammatory pseudotumor. It mainly has a pulmonary location but can appear at endobronchial or mediastinal sites rarely. While it is a benign tumor, it can sometimes be unpredictable due to its invasive characteristic as well as its resurgence after complete excision. We report the case of a patient presenting hemoptysis. The bronchoscopy revealed a bud in the left upper lobe bronchus, and the biopsy pointed to a myofibroblastic tumor. In one month, interval, the bud extended to the left main bronchus, hence the indication of a left pneumonectomy, performed by posterolateral thoracotomy. The study of the operative specimen confirmed the biopsy diagnosis. The particularity of our case is the endobronchial presentation and the fast evolution of this inflammatory myofibroblastic tumor, which requires a pneumonectomy
Narrative Dimension in Multimedia Inter-connected Narrative Stories A Semiotic-Cultural Reading in (Chambers and Mirrors)
No full textMultimedia narration is the one that uses the screen, makes use of informational media, and uses hyperlinks to make the reading process random, and allows the reader to use more than one sense and more than one response and reach more than one end. The research aims to provide a semiocultural reading in the interconnected stories collection (Chambers and Mirrors) by the Moroccan writer (Labiba Khammar). Its importance is to reveal the ability of the multimedia narration to dislodge the cultural repressed, to practice the act of rejection, to resist with the magic of writing, and to invoke the digital medium. The research concludes that the hyperlink was clear evidence of the quality of technical plot, that the author appealed to interconnected stories to write the novel, that her narrative characters had become social strata and human patterns, and that some components acquired microcosm from Arab society in general, and Moroccan in particular
Unexpected Preoperative Regression of a Thymoma: A Case Report
No full textWe report a case of unexpected spontaneous regression of thymoma in a 44-year-old patient, referred with clinical, biological, and electrophysiological findings of Myasthenia gravis. The patient was stable on synthetic Acetylcholesterase inhibitors, immunosuppressants, and corticosteroids. A chest computed tomography (January 2020) revealed a well-defined tumor in the anterior mediastinum. Surgical removal was decided. Unfortunately, because of the covid 19 pandemic, the surgical activity of the department of thoracic surgery was suspended. The patient was discharged and re-admitted nine months later. A new chest computed tomography (September 2020) was performed, revealing a net regression of the anterior mediastinal tumor. The long axis of the tumor decreased from 97mm to 28mm. A Video-assisted thoracoscopic thymothymectomy was performed. The histopathological study of the specimen revealed a Thymoma B3, according to the world health organization (WHO) classification, without any necrosis, hemorrhagic or sclerotic cells. The spontaneous regression of thymic epithelial tumors is reported as rare. Surgical excision should be performed, even if tumor volume regression is observed. After surgical resection, the anatomopathological studies of the specimens could sometimes find some elements that explain the regression of these tumors. In our case, we suppose that the intake of corticosteroids by our patient could have played a role in this tumor regression
Superabsorbent Cellulose Fibers for Reducing Shrinkage and Micro-Cracking in Concrete
No full textOne of the major durability issues in concrete structures is the cracking resulting from shrinkage. Drying shrinkage contributes a major portion of shrinkage strain in conventional concrete. Controlling the drying shrinkage of concrete can lower the total shrinkage strain and subsequently reduce the extent of cracking and enhance the durability of concrete structures. The objective of this study is to develop a pulp fiber-based concrete to reduce the drying shrinkage and micro-cracks in concrete. Using superabsorbent cellulose fibers (SCF) in the concrete mix, this study intends to develop a concrete mix with acceptable properties with reduced shrinkage strain and cracking. Using Scanning Electron Microscope images, crack growth in different concrete specimens with and without SCF is observed. Free shrinkage tests are conducted to investigate the efficiency of SCF in controlling concrete shrinkage. The test results indicated significantly reduced crack widths and a lower shrinkage strain in concrete containing SCFs.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Challenging Surgery of a Large Chest Wall Chondrosarcoma - A Case Report
No full textChondrosarcoma of a rib is a very rare malignant tumor of the bone. Most patients are present with an enlarging painful anterior chest wall tumor. We present a case of 32-years old female with a thoracoabdominal tumor size of 20 cm × 16cm involving the left 9th rib. Since chondrosarcoma is less sensitive to chemotherapy and radiotherapy, surgical treatment with extensive resection with a sufficient margin is considered first-line treatment. Sufficient soft-tissue reconstruction of the thoracic wall after extensive resection represents a formidable challenge. This article aims to illustrate the possibility of resection of the six last ribs with no complicated reconstruction technique
A Rare Case of Primary Posterior Mediastinal Hydatid Cyst with False Aortic Aneurysm
No full textHydatid cystic disease caused by the parasite Echinococcus granulosus is one of the major health problems in underdeveloped countries. Mediastinal localization is very rare. We report a rare case of hydatid disease in the posterior mediastinum with an enormous aorta defect. The patient underwent vascular graft placement without shunting or bypass
The Arizona Civics Education Project: Providing a one-stop Source for non-partisan Civic Education Learning Resources Focused on Arizona State Government
No full textabstract: The Arizona Civic Education Project is a cross-college collaboration supported by the Maricopa County Community College District to design, develop, and distribute publicly available, interactive, and engaging multimedia modules about Arizona State Government and the justice system. The modules aim to consist of high quality, professionally produced, value- neutral, fact-based, and bias-free videos, lesson plans, printable materials and activities that explain how Arizona state government is structured and how the justice system works in Arizona. The modules also identify and teach the audience how to deal with encounters within the justice system through lessons about the courts and dealing with the police. In addition to the resources we create, links are provided with attribution to other free resources that have been developed by other organizations. The targeted audience for this project is high school and college students attending public high schools and community colleges. In 2015, Arizona legislature passed the American Civics Act (House Bill 2064). This bill requires students to pass a civics test based on the United States Immigration and Naturalization civics questions. Students are required to score 60% or higher in order to graduate from high school or obtain a high school equivalency certificate. The Arizona Department of Education along with help from the Maricopa County Education Service Agency and Arizona educators have developed a mostly multiple-choice version of the required test. The modules provide helpful information that pertains to the civic test along with additional informational useful to students and educators alike.
There were a few goals kept in mind when assembling the modules and collecting information to put them together. The most important thing is to fairly and effectively educate students about their rights and the place they can hold in their own government. The youth in America, and specifically Arizona, with one of the lowest rated public education systems in the country1, needs to better understand the justice system and the way it works in order to really be able to better understand and decide the role they play in it as they grow into the adult population. We also aimed to teach students, mostly young adults, how to navigate being involved with the law and situations they may find themselves in like being arrested or having to go to court. The videos included in the related modules teach students what to do if they’re ever arrested and go over important legal actions that could affect their outcome. It was also important to provide instructors with a fair and trusted curriculum that can be taught across the state. With a shortage of qualified teacher in the state, it is impossible to provide students from all different districts and background with the same content. With the mandated civics test required to graduate from high school, it’s important that students get a fair chance at passing despite their living conditions or resources. With the modules we provide, passing the civics test along with managing other issues that pertain to young Americans, become attainable and don’t require as much additional time spent outside of school hours. The additional topics covered within our modules also provide information regarding resources that students will find useful for their families and loved ones. Students in compromised neighborhoods may have family and loved ones dealing with court cases and the justice system. Overall, we wanted to provide an unbiased, all-inclusive curriculum that can be used across the state to help students learn about all aspects of the government in Arizona. (abstract
Non-communicable diseases household survey
No full text<p><strong> </strong></p><p><strong>*Corresponding Author:</strong></p><p>Ghamdan Gamal Alkholidy ([email protected])</p><p> </p><p><strong>Abstract</strong></p><p>Non-communicable diseases (NCDs) claim 41 million lives annually, accounting for 71% of global mortality. The Middle East sees a rapid increase in NCD cases, yet Yemen remains underexplored in this context. This study aims to investigate NCD epidemiology in Sana'a City, Yemen, for 2017. Raw data from a 2017 house-to-house survey conducted by the Ministry of Public Health and Population was analyzed. Household heads reported any of the following five NCDs in the household: hypertension (HTN), diabetes mellitus (DM), bronchial asthma (BA), mental disorders (MD), and epilepsy. Data were entered and analyzed using Epi info 7.2, using 2017 projections from the 2004 census. The study encompassed 241,310 households, housing 1,592,646 individuals. Among these, 59,061 households (24.48%) included 70,178 individuals with at least one NCD. The overall NCD prevalence was 4.4%, with specific prevalence: HTN 2.3%, DM 2.2%, BA 0.4%, MD 0.27, and epilepsy 0.19%. NCD prevalence was significantly higher among females than males (5.1% vs. 3.8%; odds ratio [OR] 1.35, 95% confidence intervals [CI] 1.33–1.35), a trend mirrored in HTN (3.1% vs 1.6%; OR 1.94, 95% CI 1.90–1.98), DM (2.3% vs 2.1%; OR 1.11, 95% CI 1.09–1.13), and BA (0.5% vs 0.3%; OR 1.56, 95% CI 1.49–1.65). Conversely, MD was more prevalent among males than females (0.35% vs. 0.16%; OR 2.2, 95% CI 2.06–2.31). NCD prevalence increased with age, with nearly 18% of patients having more than one NCD, including 35.2% of HTN patients also having DM. One-quarter of surveyed households had at least one member with one or more of the five NCDs, emphasizing an overall NCD prevalence of 4.4%. These findings rely only on self-reported diagnosed cases, lacking standardized measures. In light of these findings, it is crucial to increase focus on NCDs, enhance healthcare provision, improve data collection, implement an NCDs stepwise survey, and establish an NCD surveillance system.</p><p> </p><p><i><strong>Keywords:</strong></i></p><p> Non-communicable diseases; Hypertension; Diabetes; Bronchial asthma</p>
