Management for hydatid cysts of the lung ruptured in the pleural cavity.

Abstract: Introduction Our purpose is to report our experience in the management of pulmonary hydatid cysts ruptured in the pleura. Materiel and methods: We collected all records of patients with a ruptured hydatid cyst of the lung in the pleura who underwent surgery for this in the department of thoracic surgery of the CHU Hassan II of Fes during the 6-year period that started in 2010. Results The study included 20 men and 14 women with an average age of 30.44 ± 18.4 years. Radiological findings showed a hydropneumothorax in 21 cases, hydrothorax in 10, pachypleuritis in 29, and a floating membrane in 13 cases. In all cases, pleuropulmonary decortication was associated with pericystectomy in 20 cases and parenchymal resection in 3 cases. A hydatid membrane bathing in the pleural cavity was found in 32 cases. The postoperative course was uneventful in 28 cases. Conclusion Long-term follow-up should be established to detect possible recurrences or pleural dissemination, which appear to be prevented by long-term use of anthelmintic agents.

Global research trend in the treatment of the new Coronavirus diseases (COVID-19): bibliometric analysis

Abstract: The Coronavirus 2019 (COVID-19) pandemic has caused worldwide concern and has become a major medical problem. Vaccines and therapeutics are important interventions for the management of this outbreak. This study aims to used bibliometric methods to identify research trends in the domain of therapeutics and vaccines to cure patients with COVID-19 since the beginning of the pandemic. The Web of Science Core Collection database was retrieved for articles on therapeutic approaches to coronavirus disease management published between January 1, 2020 and May 20, 2020. Identified and analyzed the data included title, corresponding author, language, publication time, publication type, research focus. A total of 1569 articles on coronavirus therapeutic means from 84 countries were published in 620 journals. We note the remarkable progressive increase in the number of publications related to research on therapies and vaccines for COVID-19. The United States provided the largest number of articles (405), followed by China (364). Journal of Medical Virology published most of them (n=40). 1005 (64.05%) were articles, 286 (18.23%) were letters, 230 (14.66%) were reviews. The terms "COVID- 19" or "SARS-CoV-2" or "Coronavirus" or "hydroxychloroquine" or "chloroquine" or "2019-nCOV" or "ACE2" or "treatment" or "remdesivir" or "pneumonia" were most frequently used, as shown in the density visualization map. A network analysis based on keyword co-occurrence revealed five distinct types of studies: clinical, biological, epidemiological, pandemic management, and therapeutics (vaccines and treatments). COVID-19 is a major disease that has had an impact on international public health at the global level. Several avenues for treatment and vaccines have been explored. Most of them focus on older drugs used to treat other diseases that have been effective for other types of coronaviruses. There is a discrepancy in the results obtained from the studies of the drugs included in this study. Randomized clinical trials are needed to evaluate older drugs and develop new treatment options.

Use of Endostemon tereticaulis (Pear.) M.Ashby and Hyptis spicigera Lam. Plant Extracts as Corrosion Green Inhibitors for Mild Steel in 1M HCl: Electrochemical and Surface Morphological Studies

Abstract: In the present study, we evaluated the effect of corrosion inhibition of ethanol extracts from Endostemon tereticaulis and Hyptis spicigera plants on mild steel in 1M HCl solution, using potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS). Also surface characterization techniques, namely scanning electron microscopy and X-ray energy dispersive spectroscopy (EDX), UV-visible spectroscopy, Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy were used. These plants extracts showed a good corrosion inhibitory efficiency. The inhibition efficiency increased with increasing of the concentration of the extracts. The potentiodynamic polarization studies showed that these extracts were mixed inhibitors, affecting both anodic and cathodic processes. Electrochemical impedance spectroscopy revealed that the corrosion phenomenon is controlled by the charge transfer process. The adsorption of organic molecules from these extracts onto the surface of mild steel followed the Langmuir isotherm. The study of the morphology of the steel surface before and after immersion showed the adsorption of the molecules of these extracts onto the surface of the steel. Analyses by UV-visible spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy confirmed the adsorption of these extracts by the formation of a protective film onto the steel surface.

Evaluation de l'impact de la mise en ligne d'un programme d'histologie-embryologie sur les performances aux examens d'étudiants en première année d'études médicales au Niger

Abstract: Contexte : Sous certaines conditions, les technologies de l’information et de la communication (TIC) peuvent apporter une valeur ajoutee a l’apprentissage des etudiants et apporter des solutions dans les milieux ou les ressources professorales sont limitees. But : Evaluer l’impact de la mise en ligne d’un module d’histologie-embryologie consacre a l’etude de l’estomac, sur les performances a l’examen d’etudiants de premiere annee de medecine a faculte des sciences de la sante (FSS) de l’Universite Abdou Moumouni (UAM) de Niamey. Materiel et methodes : 50 etudiants ont ete selectionnes au hasard et repartis en deux groupes : un groupe experimental de 25 etudiants a utilise les ressources mises en ligne du module d’histologie-embryologie, dans une demarche d’auto-formation ; un groupe temoin de 25 etudiants de la meme promotion a suivi le meme cours, dispense traditionnellement de facon magistrale. Les deux groupes ont ete evalues ensemble sur une meme epreuve de type traditionnel. Resultats : Les etudiants du groupe « experimental » ont obtenu des resultats superieurs en termes de scores aux epreuves. En revanche, la proportion d’etudiants ayant obtenu le score d’au moins 10 sur 20 n’est pas differente d’un groupe a l’autre. Conclusion : Nos resultats suggerent que l’inscription des etudiants dans un dispositif d’auto-formation associe a la mise en ligne des ressources didactiques ne les penalise pas quant a leurs chances de reussite lors d’epreuves d’evaluation sommative des apprentissages.
